The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

In the related technology, with the acceleration of modern office work rhythm and the popularization of sedentary behaviors, the problems of ischialgia, tailbone discomfort, lower limb numbness and the like caused by long-time sitting of office people are increasingly prominent. Research shows that the common office chairs mostly adopt a unified specification and a standardized structure, are difficult to consider the body shape characteristics, sitting postures and body pressure-bearing sensitive areas of different users, and easily cause local pressure concentration and support unbalance, thereby affecting the comfort and long-term health of the users.

The problem that the traditional customized office chair cushion design cannot adapt to the user comfort caused by the action and posture change of individual physiological differences in a real use scene can be solved.

The office chair cushion design method provided by the embodiment of the application can be applied to test equipment, and the test equipment is the execution main body of the office chair cushion design method provided by the embodiment of the application, and the embodiment of the application does not limit the specific type of the test equipment.

In some examples, the test device includes a seat 101, a pressure sensing layer 102, a seat cushion 103, and an information processing device 700, the pressure sensing layer is disposed on the seat cushion, the information processing device is electrically connected to the pressure sensing layer, the pressure sensing layer includes a thigh region, a ischial region, and a coccyx region, and the seat cushion correspondingly includes a thigh region, a ischial region, and a coccyx region.

The sensing element is a small pressure sensor unit and comprises a thin film resistor type sensor, a piezoelectric type sensor or a flexible capacitance type sensor which are arranged in a matrix mode. The pressure sensing layer is electrically connected with the information processing equipment and is used for collecting and transmitting pressure data.

The information processing device may be any terminal device such as a mobile phone, a tablet computer, a notebook computer, a smart television (e.g., a smart screen), an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a handheld computer, etc.

In order to better understand the design method of the office chair cushion provided by the embodiment of the application, the specific implementation process of the design method of the office chair cushion provided by the embodiment of the application is described in an exemplary manner.

Fig. 1 is a schematic flow chart of an office chair cushion design method according to an embodiment of the present application, where the office chair cushion design method includes:

And S100, detecting pressure data of a user sitting on the pressure sensing layer on the cushion through the pressure sensing layer, wherein the pressure data comprise thigh area pressure data, ischium area pressure data and coccyx area pressure data.

For example, the pressure sensing layer is arranged on the fabric substrate to ensure that the whole cushion can be bent and attached to the curved surface of the cushion, and the surface is covered with a conductive or moisture-proof surface layer to protect the sensing element. The pressure sensing layer is 50 rows and 50 columns of small pressure sensor units, such as thin film resistors, piezoelectricity or flexible capacitance sensors, and is arranged in a matrix mode and electrically connected with the information processing equipment.

For example, thigh area pressure data refers to thigh contact pressure values acquired in real time by pressure sensing layers located in the 1 st row to the 20 th row in front of the seat cushion and the 1 st column to the 50 th column area pressure dot matrix, and corresponding colors are mapped according to a preset pressure range, so as to reflect stress distribution conditions of the front edge, the inner side or the outer side of the thigh of a user.

The ischial region pressure data refers to ischial contact pressure values acquired in real time by the pressure sensing layer located in the 21 st row to the 40 th row in the front of the seat cushion and the 1 st row to the 50 th row region pressure lattice, and corresponding colors are mapped according to a preset pressure range, and the ischial region is subjected to concentrated compression, burning points or unbalanced stress characteristics.

The pressure data of the coccyx region refers to thigh contact pressure values acquired in real time by the pressure sensing layer positioned in the 41 st row to the 50 th row and the 1 st row to the 50 th row of the pressure lattice of the region in the front of the cushion, and the thigh contact pressure values are mapped into corresponding colors according to a preset pressure range so as to reflect light pressure concentration, band-shaped diffusion or pressure transfer of the coccyx region of a user.

And S200, respectively obtaining corresponding pressure heat maps according to thigh area pressure data, ischium area pressure data and coccyx area pressure data.

For example, in the pressure sensor of the 50-row 50-column small pressure sensor unit group layer, the pressure heat map refers to pressure values acquired in real time by each point on the 50×50 lattice, and the pressure values are mapped to corresponding matrix positions according to color identifications corresponding to preset pressure ranges, so that a color image visually reflecting stress distribution of each region of the cushion is generated.

It should be understood that the pressure heat map is obtained, that is, after the original pressure data is processed according to the preset mapping rule, the corresponding pressure heat map is finally generated.

S300, respectively determining design schemes of a thigh area, a ischial area and a coccyx area of the cushion according to pressure heat maps corresponding to the thigh area pressure data, the ischial area pressure data and the coccyx area pressure data;

It should be understood that by identifying the color distribution and pressure pattern of each partition in the pressure heat map, such as high pressure concentration, symmetrical imbalance or band diffusion, etc., these actual observed states are matched to predefined pressure state classes and the corresponding zoned design is selected accordingly.

It should be understood that the design scheme refers to a complete set of structure and material optimization scheme customized for a specific area of the cushion according to stress characteristics reflected by the pressure heat map, and the design scheme comprises one of geometric shapes such as grooves, binding, wedge supports and the like to be added or adjusted, and one of filler or support types such as high elastic gel, foam with different hardness, side support belts and the like to be used, and aims to improve comfort and support effects of the cushion in a targeted manner for different pressure states such as high pressure, unbalance or diffusion.

S400, synthesizing a total pressure heat map according to the pressure heat maps corresponding to thigh area pressure data, ischium area pressure data and coccyx area pressure data;

it should be understood that the synthesis refers to extracting edge lattice data between any two adjacent regions in the thigh region, the ischium region and the coccyx region from the pressure heat map corresponding to the thigh region pressure data, the ischium region pressure data and the coccyx region pressure data, overlapping and mapping each edge lattice data to the global coordinates of the cushion, deleting all other irrelevant lattice data, and synthesizing to obtain the total pressure heat map.

It should be understood that the total pressure heat map refers to a local pressure heat map generated by the thigh area, the ischium area and the coccyx area, and the total pressure heat map is a color heat map of a complete 50×50 lattice which is formed by extracting edge lattices of adjacent areas, overlapping and mapping in a global coordinate system of the cushion, removing redundant data, and is used for intuitively presenting the pressure condition of the joints of all areas of the whole cushion, so that a basis is provided for overall design adjustment.

S500, adjusting the design scheme according to the total pressure heat map.

It should be understood that adjusting is herein referred to as optimizing the local design previously established for each zone based on the overall force characteristics disclosed in the total pressure heat map to achieve a more uniform pressure distribution and better fit of the body throughout the seat cushion. Specific operations may include adding a layer of high-elasticity gel at the thigh-tail intersection zone, extending the transition zone width, or fine-tuning the individual zoned filler layout such that the zoning schemes are adjusted from individual modifications to overall synergy.

In some examples, the thigh zone pressure data, the ischial zone pressure data, and the coccyx zone pressure data each include a plurality of pressure point data, each pressure point data including a pressure value and corresponding position coordinates. S200, respectively obtaining corresponding pressure heat maps according to thigh area pressure data, ischium area pressure data and coccyx area pressure data, wherein the pressure heat maps comprise:

S210, comparing pressure values of pressure point data in thigh area pressure data, ischium area pressure data and coccyx area pressure data with preset pressure ranges to obtain identification colors corresponding to the pressure point data, wherein the preset pressure ranges comprise a plurality of different pressure intervals, and each pressure interval corresponds to one identification color.

It is understood that the preset pressure range refers to a series of pressure intervals that are defined manually before mapping the original pressure data into colors, and are used to distinguish between low pressure, medium pressure, sub-high pressure and high pressure.

For example, in order to achieve both the range of the sensor and the sitting pressure characteristics of the human body, a low pressure range of 0 to 20kPa, a medium pressure range of 20 to 40kPa, a next highest pressure range of 40 to 60kPa, and a high pressure range of 60 to 90kPa may be set.

It will be appreciated that each corresponding identification color refers to a color code in the pressure heat map for visually distinguishing between different pressure intervals, wherein the system designates a color for each pressure gear, such as low pressure, medium pressure, sub-high pressure, and high pressure, in advance, and when the real-time pressure value of a certain sensing point falls into the gear, the corresponding identification color of the gear is displayed in the heat map.

For example, a low-pressure zone of 0 to 20kPa is displayed by light blue and dark blue as the identification colors. The medium-pressure zone of 20-40kPa is displayed by taking turquoise and turquoise as the identification color. Orange is displayed in the high-pressure area of 40-60kPa, and the orange is used as a marking color. The high-pressure region of 60-90kPa is displayed by red and deep red as identification colors.

S220, generating a pressure heat map corresponding to the thigh area pressure data, the ischial area pressure data and the coccyx area pressure data according to the identification colors corresponding to the pressure point data of the thigh area pressure data, the ischial area pressure data and the coccyx area pressure data and the corresponding position coordinates, wherein the pressure heat map comprises color identification points corresponding to the pressure point data in the corresponding thigh area pressure data, the ischial area pressure data or the coccyx area pressure data.

It will be appreciated that the position coordinates refer to the relative position of each sensing point on the cushion in the mxn pressure lattice identified by a row number and a column number. Typically expressed in terms of (i, j) i represents the ith row (front to back or top to bottom) and j represents the jth column (left to right), which together determine the exact "position coordinates" of the sensing point in the global coordinate system to correspond to its pressure value and heat map pixel.

For example, in a 50×50 pressure lattice, 30 th row, 30 th column are expressed in the form of (30, 30).

It will be appreciated that the color identification points refer to the sensed pressure levels of a single sensor point, i.e., a location coordinate, represented by colors in the pressure heat maps corresponding to thigh area pressure data, ischial area pressure data, and coccyx area pressure data, each color identification point corresponding to a specific location and a specific pressure value, the relative intensity of the pressure being expressed by the shade or hue change of the color.

In some examples, S100, detecting pressure data of a user sitting on the pressure sensing layer on the seat cushion by the pressure sensing layer includes:

S110, detecting pressure data of a user sitting on the pressure sensing layer on the cushion every time when the pressure sensing layer is arranged at intervals of a first preset time, wherein the time for detecting the pressure data of the user sitting on the pressure sensing layer on the cushion every time is a second preset time, the frequency of detecting the pressure data of the user sitting on the pressure sensing layer on the cushion within the second preset time is a fixed acquisition frequency, the value range of the first preset time is 10-40 minutes, the value range of the second preset time is 5-10 minutes, and the fixed acquisition frequency is 1-2 seconds every time.

It may be understood that the detection of the first preset time period every interval means that the pressure sensing layer periodically performs pressure data acquisition at preset time intervals. The second preset time period is used for setting the time length for continuously collecting pressure data each time. The fixed acquisition frequency refers to the rate at which the sensor samples the pressure at constant time intervals.

For example, in the thigh area, the ischial area and the coccyx area, the pressure data is collected on the pressure heat map respectively with the period of 30 minutes, each time of 5 minutes, the collection frequency is collected once every 1s minutes, and then the data of 5 minutes are collected into one pressure heat map. The total measurement time of the pressure data is 8 h, and finally, the data of 16 pressure heat maps of the thigh area, the ischial area and the coccyx area for 80 minutes are respectively collected, and the data are respectively recorded as the pressure heat maps of the thigh area s1, s2 and s3...s16, the pressure heat maps of the ischial area t1, t2 and t3...t 16, and the pressure heat maps of the coccyx area m1, m2 and m 3..m16.

In some examples, determining the design of the thigh area of the seat from the pressure heat map corresponding to the thigh area pressure data in step S300 includes:

S310, determining a first thigh area design scheme under the condition that the front edge pressure concentration state of the thigh area is determined according to a pressure heat map corresponding to thigh area pressure data, wherein the first thigh area design scheme is used for indicating that a flexible circular arc edging with the radius of a is arranged at the front edge of the thigh area of the cushion, and the inner side of the flexible circular arc edging is integrally formed with a surface layer of the cushion or is fixed through hot melt bonding;

It can be understood that the concentrated state of pressure at the front edge refers to that in the pressure heat map of the thigh area, the central area of the front end of the cushion continuously and multi-frame appears a high-pressure color identification area with a lattice of 3 x 3 or more, and the high-pressure areas simultaneously and intensively appear at the bilateral symmetry positions, which indicates that the front edge of the thigh of the user bears significant and intensively distributed pressure in sitting posture. For example, in a 50×50 pressure lattice, in a thigh area formed by rows 1 to 20 and columns 1 to 50, a high-pressure color identification area appears in columns 10 to 30, and in the case that the high-pressure color identification areas appear in multiple frames continuously and intensively at symmetrical positions of the left area of the front edge of the thigh area and the right area of the front edge of the thigh area, the thigh area is determined to be in a front edge pressure concentration state;

It is understood that the flexible circular arc binding with the radius of a is arranged on the front edge of the thigh area of the cushion, and the inner side of the flexible circular arc binding is integrally formed with the surface layer of the cushion or fixed by hot melt bonding. The design scheme is used as a specific guiding instruction, when corresponding conditions occur, a production or engineering team is explicitly stated that a flexible circular arc binding with a radius of a is added at the front edge of the thigh area of the cushion, and the binding and the surface layer are fixed in an integral molding or hot melt bonding mode.

It is understood that the flexible arc edging with the radius of a arranged at the front edge refers to a section of soft edge protection strip with the arc-shaped section and the radius of curvature of a, which is additionally arranged at the edge of the flexible arc edging.

For example, on a cushion corresponding to a pressure sensitive layer of 50X 50 lattice and 5mm adjacent lattice spacing, the front edge of the thigh area corresponds to the 1 st-20 th row and 1 st-50 th column area. The design requirement of the area is that a flexible arc edging with the radius of a=10mm is arranged at the front edge of the thigh area of the cushion, namely, a section of soft TPU edging with the radius of 10mm and the width of about two lattice distances of 10mm is used for completely wrapping the front edge, the inner side surface of the edging is integrally formed with the surface layer of the cushion during injection molding, or the TPU edging is firmly combined with the surface layer by adopting hot melt adhesive in the later working procedure, so that smooth transition of the front edge is ensured, and cracking and falling are avoided.

S320, determining a second thigh area design scheme under the condition that the thigh area is in a thigh inner pressure concentrated state according to a pressure heat map corresponding to thigh area pressure data, wherein the second thigh area design scheme is used for indicating that side support belts are additionally arranged on two sides, close to a perineum, of the inner side of the thigh area of the seat cushion, and the side support belts are made of PU, TPU, TPE or high-strength composite fibers;

It is understood that the occurrence of the concentrated state of the inner thigh pressure refers to the occurrence of a high-pressure or sub-high-pressure color marking area with an area of 3×3 or more in the pressure heat map for a plurality of frames in the inner thigh area of the cushion, and the similar high-pressure color area also appears at the upstream and downstream of the area, which indicates that the inner thigh pressure of the user is concentrated and higher than other peripheral parts.

It can be understood that the side supporting belts are additionally arranged on two sides of the thigh area inside the seat cushion near the perineum, wherein the side supporting belts are PU, TPU, TPE or high-strength composite fibers, namely when the stress on the inner sides of the thighs is concentrated, namely near the root parts of the two legs and the perineum, one side supporting belt for laterally supporting is additionally arranged on the left side and the right side of the same area of the seat cushion respectively so as to disperse and support the pressure on the inner sides of the thighs, and the side supporting belts are flexible strip-shaped reinforcing pieces which are adhered or sewed along specific areas (such as the inner sides of the thighs) of the seat cushion and are generally made of PU, TPU, TPE or high-strength composite fibers and are used for providing lateral support and pressure dispersion when the local stress is concentrated, preventing discomfort caused by excessively soft or excessively hard edges of the seat cushion and enhancing the stability and the fit degree of the whole seat cushion.

For example, on a cushion corresponding to a pressure sensing layer with 50X 50 lattice and 5mm adjacent lattice spacing, the concentration area on the inner side of thigh is between the 8 th row and the 23 rd row, between the 15 th row and the 28 th row, and when in design, the positions of the 8 th row to the 15 th row in the left area, the 22 th row to the 24 th row and the 8 th row to the 15 th row in the right area are respectively attached with a TPU side supporting belt with the width of 10mm and the thickness of 2mm, and the TPU side supporting belt is fixed with the surface layer through hot melt adhesive, and is attached with the root curve of thigh, so that the internal pressure is effectively dispersed.

And S330, determining a third thigh area design scheme under the condition that the thigh area is in a thigh outside differential pressure uneven state according to a pressure heat map corresponding to thigh area pressure data, wherein the third thigh area design scheme is used for indicating a high-pressure color identification area formed by color identification points displayed based on the pressure heat map, changing a first filler with the thickness of d1 at the position of the high-pressure color identification area corresponding to the left area of the seat cushion thigh area, and adding a second filler with the thickness of d2 below the position of the high-pressure color identification area corresponding to the right area of the seat cushion thigh area, wherein the color identified in the high-pressure color identification area is a first high-pressure color, a second high-pressure color, and the pressure corresponding to the second high-pressure color is larger than the pressure corresponding to the first high-pressure color.

It is understood that the first high pressure color means that in the 60-90kPa high pressure interval, the 60-75kPa pressure interval is displayed by red as the identification color. The second high-pressure color is displayed by taking dark red as the identification color in a high-pressure interval of 60-90kPa and a pressure interval of 75-90 kPa.

It can be understood that the high-pressure color identification area refers to the color of the dot matrix on the sensor with the continuous area larger than or equal to 3×3 marked as the high-pressure gear in the pressure heat map, such as the red or deep red corresponding to the preset pressure interval 60-90kPa, so as to intuitively identify the area on the surface of the cushion, which locally bears the significantly larger pressure.

For example, for a 50×50 lattice, on a cushion corresponding to a 5mm spacing between any adjacent lattices, the 5 th to 15 th rows and 10 th to 20 th columns in a certain heat map show red, i.e., correspond to a 60-75kPa pressure interval, and the 6 th to 14 th rows and 30 th to 40 th columns show dark red, i.e., correspond to a 75-90kPa pressure interval. Then the original filling is replaced by high-resilience polyurethane foam, slow-resilience polyurethane foam or open-pore bubble-permeable foam with the thickness of 10mm at the positions from 5 th row to 15 th row and 10 th column to 20 th column on the left side of the thigh area of the cushion, and a high-elastic silica gel sheet or transparent gel block with the thickness of 15mm is additionally overlapped below the cushion positions corresponding to the deep red color identification areas from 30 th row to 14 th row and 30 th column on the right side. The middle high voltage area on the left side is uniformly buffered, and the higher high voltage point on the right side is supported in a thicker way.

It will be appreciated that in the pressure heat map corresponding to the thigh area data, two or three of the above-described thigh area leading edge pressure concentrating state, thigh inner pressure concentrating state, thigh outer pressure difference uneven state may occur simultaneously.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is an identification color dot map of a plurality of identification colors displayed in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, a distance between every two adjacent lattices in the pressure lattice is 5-10mm, and in step S310, determining that a leading edge pressure concentration state occurs in the thigh area according to the pressure heat map corresponding to the thigh area pressure data includes:

It will be appreciated that the left side region and the right side region of the front edge refer to regions of symmetrical nubs at both ends of the front edge of the thigh region of the seat cushion for monitoring whether high pressure concentrations occur at both the left and right side front edges.

For example, for a 50X 50 lattice, on a cushion corresponding to a 5mm interval between any adjacent lattices, the thigh area ranges from 1 st row to 20 th row, and 1 st column to 50 th column, the left side column ranges from 1 st row to 20 th row, and 1 st-14 th column, the right side column ranges from 1 st row to 20 th row, and 37 th-50 th column, and when the two areas respectively appear in high-voltage color identification areas with areas larger than or equal to 3X 3 lattices in 30 continuous frames, the front edge pressure concentration state can be determined. Fig. 4 is a diagram of a portion of a thigh region pressure heat map showing a concentrated state of leading edge pressure, wherein a red region is a high-pressure color identification region.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is an identification color dot map of a plurality of identification colors displayed in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, the distance between every two adjacent lattices in the pressure lattice is 5-10mm, and in step S320, determining that a thigh area has a thigh inner pressure concentration state according to the pressure heat map corresponding to thigh area pressure data includes:

S321, in a pressure heat map corresponding to detected thigh area pressure data, determining that a thigh inner pressure concentration state occurs in a thigh area formed by the 1 st row to the 2 nd M/5 th row and the 1 st column to the N th column, wherein a multi-frame continuous concentrated appearance of a secondary high-pressure color identification area appears in an area where the 8 th M/50 th row to the 15 th M/50 th row and the 23 th N/50 th column cross, the thigh area is larger than or equal to 30 frames, the secondary high-pressure color identification area represents a pressure area of 40-60kpa, the 1 st column to the 7 th M/50 th row or the 16 th M/50 th row, and the 1 st column to the 22 nd column or the 29 th N/50 th column simultaneously appear in a secondary high-pressure color identification area, the inner side of the thigh area appears in a multi-frame continuous concentrated appearance of two high-pressure color identification areas, the secondary high-pressure color identification area is larger than or equal to 3 x 3, the number of frames continuously appears in a multi-frame continuous concentrated appearance, the secondary high-pressure color identification area represents a pressure area of 40-60kpa, the secondary high-pressure color identification area corresponds to the high-pressure area of the 12 th column to the inner side of the thigh area, and the high-pressure area corresponds to the high-pressure area of the high-pressure area, and the high-pressure color identification area of the high-pressure area is in the area is more than or equal to 30M 1 st column to the area, and the high-pressure color identification area is more than the high-pressure color identification area, and the high-pressure color identification area appears in the inner area, and the high-pressure area is determined to the high-pressure color area, and appears in the thigh area, and the high-pressure color area is in the high-pressure area, and appears.

It is understood that the secondary high pressure color marking area refers to an area with a continuous area of 3x 3 lattice or more, such as yellow to orange, corresponding to the gear 40-60kPa of the secondary high pressure area in the pressure heat map, which is used to mark the area on the surface of the cushion, which is subjected to the medium upper pressure but not reaching the highest pressure level, so as to be conveniently distinguished from the medium pressure area and the high pressure area.

It will be appreciated that the first high pressure color means that in the 40-60kPa high pressure color identification interval, the color is displayed by orange as the identification color in the 40-50kPa pressure interval. The second high-pressure color is displayed by taking orange red as a marking color in a high-pressure region of 50-60 kPa.

For example, on a cushion composed of a 50×50 lattice and a pressure-sensitive layer with an arbitrary lattice spacing of 5mm, if the 8 th to 15 th rows, 23 rd to 28 th columns of small areas are continuously equal to or larger than 30 frames in the heat map, the next highest-pressure color identification area appears, and the next highest-pressure color identification or the highest-pressure color identification with an area of 3×3 lattice or more appears in the left area, 10 th to 12 rows, 24 th to 25 th columns and 10 th to 12 th rows, and 26 th to 27 th columns of areas on both sides of the next highest-pressure color identification area, respectively, then the concentrated state of the thigh internal pressure can be determined. Fig. 5 is a diagram showing a partial schematic view of the pressure heat map of the thigh, showing the concentrated state of the thigh pressure, wherein the red and dark red areas are the high-pressure color identification areas, and the orange yellow and the orange red are the secondary high-pressure color identification areas. This indicates that the medial aspect of the leg root is significantly more stressed than the other thigh areas of the periphery, and that lateral braces or softer padding are required to distribute the pressure at the medial aspect of the leg root.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is a mark color dot map of a plurality of mark colors displayed in the pressure lattice of M rows and N columns, wherein m=n=50k, k is a positive integer, the distance between every two adjacent lattices in the pressure lattice is 5-10mm, and in step S330, the thigh outside pressure difference state in the thigh area is determined according to the pressure heat map corresponding to the thigh area pressure data, including:

S331, in a pressure heat map corresponding to detected thigh area pressure data, in a thigh area formed by 1 st row to 2M/5 th row, 1 st column to N th column, a thigh outside pressure difference state is determined under the conditions that a thigh area is formed by 10M/50 th row to 12M/50 th row and 2N/50 th column to 4N/50 th column crossing area, a next high pressure color identification area multi-frame continuously and intensively appears, a thigh area right 8M/50 th row to 10M/50 th row and 47N/50 th column to 49N/50 th column crossing area continuously appears, medium pressure color identification area multi-frame continuously and appears, the rest thigh area lattice 1 st to 9M/50 th row or 13M/50 th to 2M/5 th row and 5N/50 th to 46N/50 th column are in the thigh area, wherein the medium pressure color identification area is larger than or equal to 3×3 lattice, the continuously appears, the medium pressure color identification area is equal to 30 th medium pressure frame continuously appears, the medium pressure color identification area lattice 1 st to 9M/50 th row or 13M/50 th to 2M/50 th column, and 5N/50 th to 46N/50 th column are in the thigh area, the medium pressure outside pressure difference state appears, the medium pressure color area is determined, the medium pressure color area is equal to the medium pressure color area corresponding to the medium pressure color area, and the medium pressure color area corresponds to the medium pressure color area 20 th color area, and the medium pressure color area corresponds to the medium pressure color area.

It is understood that the medium-pressure color marking area refers to an area with an area larger than or equal to 3 x 3 lattice, which is mapped to a color cyan and yellow green corresponding to the medium-pressure of 20-40kPa in the pressure heat map and appears when the areas of the color marking areas are continuously formed on the map, and is used for marking a part bearing the medium pressure on the surface of the cushion. These areas represent the contact pressure of the user at that location being both higher than the low pressure area and lower than the next highest pressure color identification area.

It is understood that the first medium pressure color means that in the medium pressure interval of 20-40kPa, the display is made by cyan as the identification color in the pressure interval of 20-40 kPa. The second medium-pressure color is displayed by taking yellow green as the identification color in the pressure interval of 30-40 kPa.

For example, on a cushion formed by a 50 x 50 lattice and a pressure sensing layer with an arbitrary lattice spacing of 5mm, a sub-high pressure color identification area appears in a 3 x 3 area of 10 th to 12 th rows and 2 nd to 4 th columns of the left side area of the thigh area in a pressure heat map, a medium pressure color identification area appears in a 3 x 3 area of 8 th to 10 th rows and 47 th to 49 th columns of the right side area of the thigh area in 30 consecutive frames, and the rest lattices of the thigh area are also medium pressure color identification areas, so that the pressure difference state outside the thigh can be judged. Fig. 6 is a diagram showing a partial schematic view of a pressure difference state outside the thigh in a pressure heat map of the thigh region, wherein a part consisting of red and dark red regions in the diagram is a high-pressure color identification region, a part consisting of orange yellow and orange red is a secondary high-pressure color identification region, and a part consisting of cyan and yellow green is a medium-pressure color identification region. This condition indicates that the outer side of one side bears significantly higher than the other side, requiring the addition of a stiffer packing or support structure under the high pressure side, and thickening the flexible packing on the low pressure side to achieve even distribution of side-to-side pressure.

In some examples, determining the design of the ischial region of the seat according to the pressure heat map corresponding to the ischial region pressure data in step S300 includes:

S340, determining a first ischial zone design scheme under the condition that ischial zone is in an ischial centralized compression state according to a pressure heat map corresponding to ischial zone pressure data, wherein the first ischial zone design scheme is used for indicating that a buffer groove with the depth d is formed in the ischial zone of the cushion;

it will be appreciated that the occurrence of ischial concentrated compression conditions means that the region is subjected to excessive compression over a prolonged period of time, possibly resulting in discomfort or tissue damage.

It can be understood that the indication of providing the cushion recess with depth d in the ischial region of the cushion means that when the pressure heat map shows that there is an obvious and continuous high-pressure region in the ischial region, a structural adjustment scheme is proposed according to the state, i.e. a concave structure with depth d is dug inside the cushion in the region so as to relieve local pressure concentration.

For example, a 50×50 lattice is formed, a cushion corresponding to a pressure sensor with a 5mm interval between any adjacent lattices is provided with high-pressure color identification points between the 25 th row and the 30 th row and between the 23 rd row and the 27 th row for continuously exceeding 30 seconds, and a cushion foam layer in the area is provided with a buffer groove corresponding to the detection area, the area is 30 mm ×25× 25 mm, and the depth is 8 mm. The concave area can enable the compression area to sink through the structure, so that pressure evacuation and distribution optimization are realized, and comfort and safety are improved.

S350, determining a second ischial zone design scheme under the condition that an ischial zone asymmetric high-pressure unbalance state occurs in the ischial zone according to a pressure heat map corresponding to pressure data of the ischial zone, wherein the second ischial zone design scheme is used for indicating that the fabric of the seat cushion in the ischial zone of the seat cushion is set to be of a multi-material layered structure, the center of the ischial zone is made of softer materials, the corresponding position of a high-pressure center point on a color mark of the ischial zone identified based on the pressure heat map is made of softer materials, the corresponding position of the center point is taken as an origin, and the hardness of the materials is gradually transited to harder materials to the position corresponding to a 6X 6 lattice coverage area of the peripheral pressure heat map on the seat cushion;

It can be understood that the asymmetric high-pressure unbalanced state of the ischial region refers to that in the left and right ischial regions of the cushion, the pressure born by one side for a long time is obviously higher than that of the other side, and the high-pressure state continuously appears, which indicates that the gravity center of the body of a user has obvious deviation, so that uneven stress on the two sides of the ischial is formed to be unbalanced, and the ischial bones on the left and right should share the body weight evenly under ideal sitting postures.

It can be understood that the cushion fabric for indicating the ischial region of the cushion is arranged into a multi-material layered structure, the center of the ischial region is made of softer material, the corresponding position of the high-pressure center point on the color mark of the ischial region identified based on the pressure heat map is made of softer material, the corresponding position of the center point is taken as the origin, the position corresponding to the 6 x 6 lattice coverage area of the peripheral pressure heat map on the cushion is used, and the hardness of the material is gradually transited to harder material;

For example, on a cushion corresponding to a pressure sensor with a space of 5mm between any two adjacent lattices, a high-pressure center point of a ischium zone identified by a pressure heat map falls on a 28 th row and a 25 th column, and the point is taken as an origin, so that gradual layering of material hardness can be realized in a6×6 lattice area, namely a 25 th row to a 30 th row and a 23 rd column to a 28 th column, a memory sponge is placed in the 28 th row and the 25 th column of the center point, a first annular range close to the center, namely a 3×3 lattice range, high-resilience polyurethane foam is selected from the 27 th row to the 29 th row and the 24 th column to the 26 th column, the density is 45kg/m3, a frame lattice of the whole 6×6 zone is adopted from the 25 th row to the 30 th row and the 23 rd column to the 28 th column, and the density is 60kg/m3. The hardness of the material is gradually increased from the high-pressure center of the ischial bones outwards, so that soft fit is provided at the most core area, and enough support is provided at the edge, thereby realizing smooth transition of local pressure.

And S360, determining a third ischial zone design scheme under the condition that the ischial zone is in a ischial zone continuous high-pressure burning point state according to a pressure heat map corresponding to the ischial zone pressure data, wherein the third ischial zone design scheme is used for indicating that a ischial zone high-pressure color identification zone identified based on the pressure heat map is replaced by a medium-hardness elastic material on a position corresponding to the ischial zone on the seat cushion ischial zone, the medium-hardness elastic material is used as a supporting transition zone, and the surface materials of the rest color identification zones adopt PU fabrics or ice silk mesh fabrics.

It will be understood that the presence of the continuous high-pressure glowing point state of the ischial region means that in the barothermogram, the ischial region as a whole presents a large-area sub-high-pressure color mark and stably appears in 30 frames or more in succession, while the high-pressure color mark is sporadically reduced in two small ranges on the left and right, respectively, but the total number of the highest-pressure points is less than three or the appearance time is shorter than 30 frames. This state indicates that the ischial region is stressed with high strength and is sustained, so that the local burning pain is easily caused, and the pressure is required to be dispersed and relieved through material or structure adjustment.

It will be appreciated that the medium durometer elastomeric material is a polyurethane elastomer having a density of 50kg/m 3. For example, on a cushion corresponding to a pressure sensor with a spacing of 5mm between any two adjacent lattices, a pressure heat map shows that high-pressure color identification areas continuously appear in the 25 th row to the 30 th row and the 22 nd row to the 27 th row in the ischial region, then original foam is replaced by polyurethane elastomer with medium hardness and density of 50kg/m3 in the area of 30mm x 30mm on the cushion corresponding to the color expression area so as to form a supporting transition area, and the rest range of the ischial region still keeps the surface material as PU fabric or ice silk screen cloth, thereby ensuring the consistency of the whole touch and the air permeability and wear resistance. The high-pressure area of the core is supported and rebounded more strongly, and the peripheral area of the high-pressure area does not generate discomfort due to abrupt change of materials.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is a mark color dot map of a plurality of mark colors displayed in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, the distance between the corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step S340, determining that the ischial zone has a ischial centralized compression state according to the pressure heat map corresponding to the ischial zone pressure data includes:

S341, in the pressure heat map corresponding to the detected ischium zone pressure data, in the ischium zone formed by the 21M/50 to 40M/50 row, the 1 st to N th columns, the ischium centralized compression state is determined under the condition that the ischium zone is detected in the crossing area of the 28M/50 to 30M/50 row and the 24N/50 to 26N/50 column, a plurality of frames of high-pressure color identification zones are continuously and intensively appeared, the sub-high-pressure color identification zones appear at more than the 27M/50 to 31M/50 row and the 22N/50 to 28N/50 column, the color identification zones appear in the 21M/50 to 27M/50 row or the 31M/50 to 40M/50 row and the 1 st to 23N/50 column, wherein the range of the high-pressure color identification zone is larger than or equal to 3 x 3 area, the sub-high-pressure color identification zones appear at a plurality of positions indicate that the color identification zones are more than three positions and accord with the sub-high-pressure color identification zone, the color identification zone appears at a range of greater than or equal to 3 x is not met, and the color identification zone appears at a five positions of the high-pressure zone is not equal to 3 x.

For example, for a 50×50 lattice, on the cushion corresponding to the pressure sensing layer with a 5mm interval between any adjacent lattices, in the ischial region formed by the 21 st to 40 th rows and the 1 st to 50 th columns, the high-voltage color identification region with 3×3 lattice is formed by the continuous multi-frame appearance surface of the small region crossing the 28 th to 30 th rows and the 24 th to 26 th columns in the center of the ischial region of the cushion, and meanwhile, the secondary high-voltage color identification region is formed by the peripheral region, namely the 27 th to 31 st rows and the 22 nd to 28 th columns, which indicates that the stress of the ischial region of the user is highly concentrated, the pressure peak is obvious, and the ischial centralized compression state is determined. Fig. 7 is a diagram showing a partial schematic view of a ischial centralized compression state in a pressure heat map of an ischial region, wherein a part consisting of red and deep red regions in the diagram is a high-pressure color identification region, a part consisting of orange yellow and orange red is a secondary high-pressure color identification region, and a part consisting of cyan and yellow green is a medium-pressure color identification region. Indicating a tendency to cause local discomfort or tissue compression, it is necessary to provide a relief groove in this area or to replace it with a softer material to distribute the pressure.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is a mark color dot map of a plurality of mark colors in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, a distance between corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step S350, it is determined that a continuous high-pressure burning state of the ischial region occurs in the ischial region according to the pressure heat map corresponding to the pressure data of the ischial region, including:

S351, in a pressure heat map corresponding to the detected ischium zone pressure data, in an ischium zone formed by 21M/50 to 40M/50 rows and 1 st to N th columns, large-area secondary high-pressure color identification zones continuously and intensively appear in the whole area, color identification zones are obviously unevenly distributed in a lattice of the pressure heat map, high-pressure color identification zones are detected in an intersecting area of the 25M/50 to 29M/50 rows and the 8N/50 to 12N/50 columns, secondary high-pressure color identification zones appear in an intersecting area of the 30M/50 to 34M/50 rows and the 38N/50 columns to 42N/50 columns, secondary high-pressure color identification zones appear in an intersecting area of the 21M/50 rows to 24M/50 rows and the 1 st to 7N/50 columns, and a lattice of the 35M/50 rows to 40M/50 rows to 37N/50 columns, the secondary high-pressure color identification zones continuously appear in the detecting area, the secondary high-pressure color identification zones appear in the local areas in the intersecting area of the lattice, the number of the high-pressure color identification zones is higher than or equal to the number of the high-pressure color identification zones in a small number of the 3 x-area of the high-pressure color identification zones, and the number of the secondary high-pressure color identification zones continuously appears in the small-area of the lattice is equal to or more than the large-area of the high-pressure color identification zones, wherein the number of the secondary high-pressure color identification zones is determined to be equal to the large-area of the high-pressure color identification zones.

For example, when the yellow region of the 50×50 lattice is formed by the pressure sensing layer with the 5mm adjacent dot spacing, in the ischial region formed by the 21 st row to the 40 th row and the 1 st column to the 50 th column, if the number of consecutive multi-frames of the 21 st to 40 th rows and the 1 st to 50 th columns is 3 or more and the area is 6×6 lattice or more, the yellow region is the next high-voltage color identification region, the left region is 25 th to 29 th rows, the 8 th to 12 th columns are listed to present the high-voltage color identification region, the right region is 30 th to 34 th rows, the 38 th to 42 th columns are present the next high-voltage color identification region, and the other regions are 21 st to 24 th and 1 st to 7 th columns, 35 th to 40 th and 13 th to 37 th columns are mainly medium-voltage color identification regions, and the sum of the number is less than three or one of the next high-voltage color identification region and the high-voltage color identification region is less than 30 frames in the detection region, the ischial region is determined to be in the continuous high-voltage ignition point state. Fig. 8 is a diagram showing a partial schematic view of an asymmetric high-pressure imbalance state in a pressure heat map of an ischial region, wherein a part consisting of red and dark red regions is a high-pressure color identification region, a part consisting of orange and red is a secondary high-pressure color identification region, and a part consisting of cyan and yellow-green is a medium-pressure color identification region.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is an identification color dot map of a plurality of identification colors displayed in the pressure lattice of M rows and N columns, wherein m=n=50k, k is a positive integer, the distance between the corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step S360, the ischial zone asymmetric high-pressure unbalanced state is determined according to the pressure heat map corresponding to the ischial zone pressure data, including:

In the pressure heat map corresponding to the detected ischium zone pressure data, in the ischium zone formed by the 21M/50 row to the 40M/50 row and the 1 st column to the N column, in the crossing area of the 29M/50 row to the 31M/50 row and the 24N/50 column to the 26N/50 column, a local small-range high-pressure color identification zone multi-frame continuous concentrated appearance is detected, in the peripheral area of the 28M/50 row to the 32M/50 row and the 22N/50 column to the 28N/50 column, a secondary high-pressure color identification zone is repeatedly appeared, in the rest area of the ischium zone, in the 21M/50 row to the 28M/50 row or the 32M/50 row to the 40M/50 row and in the 1 st column to the 23N/50 column or the 27N/50 column, the ischium zone is determined to be an asymmetric high-pressure unbalanced state under the condition that the local small-range high-pressure color identification zone multi-frame continuous concentrated appearance is detected, wherein the local small-range high-pressure color identification zone indicates that the number of the high-pressure color identification zone is greater than or equal to 3 times of the multiple high-frame concentrated appearance area, and the number of the local small-range high-pressure color identification zone is larger than or equal to the multiple high-frame number of the multiple high-color identification zone appear in the multiple-frame continuous high-pressure color zone.

For example, when a high-pressure color identification region is detected to appear continuously for 50 frames and more in the 3×3 lattice range of the 29 st to 31 st and 24 th to 26 th columns in the ischial region formed by the 21 st to 40 th rows and the 1 st to 50 th columns on the cushion composed of the pressure sensing layer with the 50×50 lattice and the 5mm adjacent point spacing, three or more sub-high-pressure color identification regions with the area not smaller than 3×3 lattice appear in the 28 th to 32 nd rows and the 22 nd to 28 th columns of the periphery, and meanwhile, when only the medium-pressure color identification region appears in the rest of the ischial region, the ischial region can be judged to appear in an asymmetric high-pressure unbalanced state, fig. 9 is a partial schematic diagram showing the continuous high-pressure burning point state of the ischial region, wherein the red and deep red regions constitute the high-pressure color identification region, the orange-yellow and orange-red constitute the sub-high-pressure color identification region, and the green and the yellow-green constitute the medium-pressure color identification region.

The sitting posture inclination of the user or unbalance of the support at two sides of the cushion is described, and the cushion structure is required to be adjusted to realize pressure balanced distribution.

It will be appreciated that in the pressure heat map corresponding to the ischial region data, two or three of the ischial region ischial concentrated compression state, ischial region asymmetric high pressure imbalance state, ischial region sustained high pressure glowing point state described above may occur simultaneously.

In some examples, in step S300, determining a design of the coccyx region of the seat according to the pressure heat map corresponding to the coccyx region pressure data includes:

S370, determining a first tailbone region design scheme under the condition that the tailbone region is in a tailbone light pressure centralized state according to a pressure heat map corresponding to pressure data of the tailbone region, wherein the first tailbone region design scheme is used for indicating a color identification region centralized position formed by color identification points displayed based on the pressure heat map on the tailbone region of the cushion, and making a buffer girdle at the edge of a hole at a position corresponding to the position where the tailbone region and the color identification region centralized position of the cushion, and filling memory cotton;

It can be understood that the method is used for indicating the concentrated position of the color identification area formed by the color identification points displayed based on the pressure heat map on the tailbone area of the cushion, the buffer endless belt is made at the edge of the hole at the corresponding position of the concentrated position of the tailbone area and the color identification area of the cushion, and the filling of the memory cotton means that when the color identification points which occur in a concentrated mode exist in a certain small range of the tailbone area through the pressure heat map, the condition that the tailbone is in a light pressure concentrated state can be judged. In order to relieve the pressure of the part, a buffer structure is arranged at a position on the cushion corresponding to the concentrated position of the color identification area.

For example, in a cushion composed of a 50 x 50 lattice, pressure sensitive layers with a 5m spacing between any adjacent lattices, the coccyx region is at rows 41-50. If a pressure value above 40kPa is continuously detected in the 45 th row, 25 th to 26 th column range, it can be considered that the color identification points appear in a concentrated manner. The cushion material at the corresponding position is perforated or provided with a hole with the diameter of about 15-20mm, a flexible buffer ring belt is arranged at the edge of the hole to form an elastic support edge, soft memory cotton material is filled in the hole to provide the adaptive deformation and decompression effects, and an annular support and center buffer structure is integrally formed, so that the pressing sense of a concentrated stress area of the coccyx is reduced, and the comfort of long-time sitting is improved.

S380, determining a second coccyx region design scheme under the condition that a coccyx band-shaped high-pressure diffusion state occurs in a coccyx region according to a pressure heat map corresponding to the coccyx region pressure data, wherein the second coccyx region design scheme is used for indicating that a softer sponge is used in the middle region of the coccyx region of the cushion, and gradually transiting to medium hardness outwards;

It will be understood that the presence of a band-shaped hyperbaric diffusion state of the coccyx refers to the presence of a linear or band-shaped hyperbaric region extending in the vertical direction in the pressure heat map and consisting of a plurality of adjacent hyperbaric color marker points, which indicates that the coccyx is continuously pressed around, and is prone to cause coccyx tenderness or discomfort.

It can be understood that the soft sponge is used in the middle area of the tailbone area of the cushion, and gradually transits to medium hardness outwards, so that the middle position of the tailbone area of the cushion is covered with a layer of low-density slow rebound memory sponge to release the pressure of the tailbone to the greatest extent, and then the polyurethane foam with faster rebound and higher density is replaced from the area outwards layer by layer, so that the hardness of the material is gradually enhanced, the softness and comfort of the center are ensured, and the periphery is provided with enough support to form a smooth transition zone from soft to hard.

For example, on a cushion composed of a 50X 50 lattice, arbitrary lattice spacing 5mm pressure sensitive layer, the coccyx region may be defined as the region of rows 42-48, 22-28 covering approximately 30X 30mm of the cushion area. Setting a slow rebound material with the density of 20-30kg/m3 at the center position by taking the center point of the area, namely the 45 th row and the 25 th column as cores, and then increasing the hardness of a bit of material to 35kg/m3 and 40kg/m3 by increasing a dot matrix unit every time when the material expands outwards for one circle, so as to realize a gradual change structure with slightly harder material from inside to outside. The buffer is provided at the central point where the user presses the coccyx greatly, and the support is provided at the peripheral area, so that coccyx pressing pain, burning sensation or ischialgia are effectively reduced.

S390, determining a third tailbone region design scheme under the condition that the tailbone region is in a tailbone band-shaped high-pressure diffusion state according to a pressure heat map corresponding to the tailbone region pressure data, wherein the third tailbone region design scheme is used for indicating that a wedge-shaped supporting region is reserved in a central lower region of the rearmost tailbone region of the cushion, the front part is high, the rear part is low, the tail end is lifted, a wedge-shaped cushion block with the front end thickness h₀ and the tail end maximum height h is arranged, and covering microfiber PU or breathable soft cloth on the surface.

It will be appreciated that the presence of a band-like high pressure diffusion state of the coccyx refers to the presence of a longitudinally extending high pressure region in the coccyx region in the pressure heat map, indicating that pressure has spread from the center of the coccyx to the surrounding band-like region, indicating that the user's coccyx is continuously compressed throughout and requires optimal relief in the design by cushioning the decompression band or material zonal transition.

It can be understood that a wedge-shaped supporting area is reserved in the area below the rearmost center of the tailbone area of the cushion, the front part is high and the rear part is low, the tail part is lifted, a wedge-shaped cushion block with the front end thickness h₀ and the tail part maximum height h is arranged, microfiber PU or breathable soft cloth is covered on the surface, and in order to relieve the pressure of the tailbone area, a wedge-shaped supporting area is reserved in the position of the rearmost part of the cushion and the right below the tailbone. The thickness of the front end of the wedge-shaped area is h₀, the highest point of the rear end is h, a supporting effect of lifting obliquely upwards can be provided, the vertical pressure of the tail bone can be relieved when the tail end is lifted, and the sitting posture stability and the comfort are improved.

For example, on a cushion formed by a pressure sensing layer with 50X 50 lattice and 5mm adjacent point spacing, the relief scheme under the tail bone band-shaped high-pressure diffusion state can be realized by arranging a wedge-shaped buffer structure with low front and high rear in the central axis area of the tail part of the cushion, wherein the structure is positioned in the range of 42 th to 49 th rows and 20 th to 30 th columns, the thickness of the front edge is 10mm, the thickness of the tail end is gradually transited to 25mm, an obliquely lifted lifting form is formed, the longitudinal band-shaped compression of the tail bone area is effectively relieved, the surface of the cushion is coated by breathable soft PU or ice silk cloth, and the fitting sense and the comfort are improved.

It will be appreciated that two or three of the above-described tailbone light pressure concentration state, tailbone band-like high pressure diffusion state, and tailbone center of pressure rearward state may occur simultaneously in the pressure heat map corresponding to the tailbone region data.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is an identification color dot map of a plurality of identification colors in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, a distance between corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step S370, determining that a tailbone light pressure concentration state occurs in the tailbone region according to the pressure heat map corresponding to the tailbone region pressure data includes:

s371, in the pressure heat map corresponding to the detected pressure data of the coccyx region, in the coccyx region formed by the 41M/50 th row to the 50M/50 th row, the whole appears as a medium-pressure color identification region or a low-pressure color identification region multiframe continuously appears, in the crossing region of the 44M/50 th to 45M/50 th row and the 24N/50 th to 26N/50 th row, the next high-pressure color identification region or the high-pressure color identification region multiframe continuously appears, and in the range of the 43M/50 th to 46M/50 th row and the 22N/50 th to 28N/50 th row, the light pressure concentration state of the coccyx is determined under the condition that the multiframe continuously appears as the medium-pressure color identification region or the low-pressure color identification region multiframe continuously, wherein the marked color in the low-pressure color identification region is the first low-pressure color, the whole appears as the medium-pressure color identification region or the low-pressure color identification region, and the range of the present color identification region is larger than or equal to 6X 6 lattice area.

It will be appreciated that the low pressure color identified region refers to the region of the cushion pressure heat map where the pressure value represented by the color identification is small.

It will be appreciated that the first low pressure color means that in the 0-20kPa low pressure interval, the 0-10kPa pressure interval is displayed by light blue as the identification color. The second low pressure color is displayed by blue as the identification color in the 10-20kPa pressure zone.

For example, on a cushion corresponding to a pressure sensor with a space of 5mm between any two adjacent lattices, the 41 st row to the 50 th row, the 1 st column to the 50 th column form a tailbone region, most lattices of the 41 st row to the 50 th row of the tailbone region of the cushion continuously show color marks of medium-pressure regions 20-40kPa or low-pressure regions 0-20kPa, but in a central small region, a region of about 10mm multiplied by 15mm, which is intersected with the 24 th to the 26 th columns, of the 44 th row to the 45 th row is larger than 30 frames, the color marks of the sub-high-pressure regions 40-60kPa or the high-pressure regions 60-90kPa appear, and the periphery of the region is still the medium-low-pressure region. And determining the tail bone light pressure concentration state of the tail bone region. Fig. 10 is a diagram showing a partial schematic view of a tailbone region in which tailbone light pressure is concentrated in a tailbone region pressure heat map, wherein a red and dark red region part is a high-pressure color identification region, an orange and red region part is a secondary high-pressure color identification region, a cyan and yellow-green region part is a medium-pressure color identification region, and a light blue and dark blue region part is a low-pressure color identification region. The whole pressure is not large but the local pressure peak is perceived, and a buffer girdle and memory cotton are added in the small range to disperse the slight compression of the area.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is an identification color dot map of a plurality of identification colors in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, a distance between corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step S380, determining that a tailbone band-shaped high-pressure diffusion state occurs in the tailbone region according to the pressure heat map corresponding to the tailbone region pressure data, including:

S381, in the pressure heat map corresponding to the detected pressure data of the coccyx region, the 46M/50 to 50M/50 rows, the 1 st to 50M/50 columns and the 1 st to N columns in the coccyx region formed by the 41M/50 to 50M/50 rows, the 1 st to N columns are in strip-shaped distribution, the next high-pressure color identification region is continuously and intensively arranged for 30 frames in the 41M/50 to 45M/50 rows, the 1 st to N columns are in the 1 st to 50M/50 rows, the 1 st to 10N/50 columns or the 40N/50 to 50N/50 columns, and the strip-shaped high-pressure expansion state of the coccyx is determined under the condition that the medium-pressure color identification region is continuously and intensively arranged for 30 frames, wherein the high-pressure color identification region is arranged in strip-shaped distribution, and the high-pressure color identification region is a rectangular lattice larger than 3 x 6 on the pressure heat map.

For example, in a cushion formed by a 50×50 lattice and a pressure sensing layer with a 5mm interval between any adjacent lattices, in a tailbone region formed by columns 41 to 50, between columns 42 to 48, a plurality of points continuously appear between columns 24 to 26, the pressure value exceeds a set high-pressure threshold value by 60 kPa or more, a high-pressure band with a longitudinal length of about 30 to 40mm and a transverse width of about 10 to 15mm is formed, three or more regions appear in a multi-frame continuous concentration in a sub-high-pressure color identification region appear in columns 41 to 45, and columns 41 to 50, columns 1 to 10 or 40 to 50, and a multi-frame continuous concentration in a medium-pressure color identification region appear, and a band-shaped high-pressure spread state of the tailbone is determined. Fig. 11 is a diagram showing a part of a tail bone band-shaped high-pressure diffusion state in a screenshot in a tail bone region pressure heat map, wherein a part consisting of red and dark red regions in the diagram is a high-pressure color identification region, a part consisting of orange and orange red is a secondary high-pressure color identification region, and a part consisting of cyan and yellow green is a medium-pressure color identification region.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is a mark color dot map of a plurality of mark colors displayed in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, a distance between corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step 390, determining that a tailbone pressure center backward movement state occurs in the tailbone region according to the pressure heat map corresponding to the tailbone pressure data includes:

S391, in the pressure heat map corresponding to the detected pressure data of the coccyx region, in the coccyx region formed by the 41M/50 to 50M/50 row and the 1 st to N th columns, the high-pressure color identification region continuously and intensively appears in the crossing region of the 44M/50 to 45M/50 row and the 24N/50 to 26N/50 th columns, the higher the high-pressure color identification region is, the darker the color identification color is, the higher the high-pressure color identification region starts to be transferred to the 46M/50 to 50M/50 row and the later region along with the time, the other regions determine that the coccyx pressure center backwardly moves, the darker the color system corresponding to the color identification point is, the higher the high-pressure color identification region starts to be transferred to the 46M/50 to 50M/50 row and the later region, the higher the high-pressure color identification region gradually disappears along with the continuous frame, and the higher-pressure color identification region starts to appear in the 46M/50 to the 50M/50 row and the later region.

For example, in a heat map of a pressure sensing layer cushion composed of 50×50 dot matrix and 5mm dot spacing, in the range of 41 st row to 50 th row, 1 st column to 50 th column, the high-pressure color identification area appears in 50 continuous frames in the crossing area of 44 th row to 45 th row and 24 th column to 26 th column, and the high-pressure dots gradually deepen in color and move to 46 th row to 50 th row further back to the cushion, namely the original area high-pressure dots are reduced and the rear high-pressure dots are increased, and meanwhile, the other areas of the cushion basically keep the medium-pressure level, so that the tailbone pressure center backward movement state can be judged. Fig. 12 is a diagram showing a part of a tailbone pressure center backward moving state in a tailbone pressure heat map, wherein a part consisting of red and dark red areas is a high-pressure color identification area, a part consisting of orange and red is a secondary high-pressure color identification area, and a part consisting of cyan and yellow-green is a medium-pressure color identification area. This means that the coccyx region is continuously pressurized and moved backwards in time, the caudal pressure distribution is improved by the structure or the filler.

In some examples, S220, the synthesizing a total pressure heat map according to the pressure heat maps corresponding to the thigh area pressure data, the ischial area pressure data and the coccyx area pressure data includes:

S221, extracting edge lattice data between any two adjacent regions in the thigh region, the ischium region and the coccyx region from the pressure heat map corresponding to the thigh region pressure data, the ischium region pressure data and the coccyx region pressure data, overlapping and mapping the edge lattice data to global coordinates of a cushion, deleting all other irrelevant lattice data, and synthesizing to obtain a total pressure heat map.

It can be understood that extracting the edge lattice data between any two adjacent regions in the thigh region, the ischial region and the coccyx region, in this sentence, "extracting" refers to screening out the part of lattice data located on the boundary edge of two functional regions from the lattice pressure data acquired by the whole pressure sensing layer, for analyzing the pressure change, the transition relationship or the partition rationality at the boundary.

It is understood that the edge lattice data refers to data of pressure sensing points located on boundary edges between two functional areas such as thigh area and ischial area or ischial area and coccyx area in a cushion sensing layer composed of a plurality of pressure sensing points arranged regularly.

For example, on a cushion composed of a 50×50 lattice and a pressure sensing layer with a 5mm interval between any adjacent points, edge lattice data refers to the border between adjacent regions such as thigh region, ischium region, coccyx region, etc. the thigh region is 1 st row to 20 th row, 1 st column to 50 th column, ischium region 21 st row to 40 th row, 1 st column to 50 th column, coccyx region 41 st row to 50 th row, 1 st column to 50 th column, the lattice between 20 th row and 21 st row, and the lattice between 40 th row and 41 st row, which are edge lattice data for reflecting the transition condition of pressure distribution between the two regions, which is helpful for identifying the location of pressure discontinuity, local abrupt change or abnormal structural connection.

It will be appreciated that the global coordinates of the overlay map to the cushion refer to the pressure data extracted from the various local functional areas in the pressure sensitive layer, such as thigh area, ischial area, coccyx area, and corresponding to a fixed, unified coordinate system throughout the cushion for overall analysis and comparison.

It can be understood that deleting all other irrelevant lattice data means that when processing pressure data, only effective pressure lattice data in the relevant areas of the analysis target such as thigh area, ischial area and coccyx area are reserved, and the rest of data in the target area not on the boundary edge are all removed so as to improve analysis efficiency and result accuracy.

In some examples, S500, adjusting the design from the total pressure heat map includes:

S510, determining an overall adjustment scheme of the seat cushion under the condition that a thigh-sitting-tail junction zone high-pressure state is formed in the whole seat cushion according to a total pressure heat map corresponding to total pressure data, wherein the overall adjustment scheme is used for indicating that a thigh zone and a ischial zone edge junction zone corresponding to the seat cushion are set to be high-elastic gel layers, arranging high-elastic gel inserts according to the center coordinates of the junction zones along the row-column orthogonal direction +/-1-2 lattice distance, and expanding the color identification zone outwards by 3-5 lattice distances to form a transition zone, wherein the high-elastic gel layers adopt edge-to-center gradual-change density foam, high-density foam is selected at the edge, and the transition is gradually carried out inwards to medium-density foam and then low-density foam.

It can be understood that the high-pressure state of the thigh-seat-tail junction zone refers to the junction area among the thigh area, the ischial area and the coccyx area of the seat cushion, and the pressure area higher than the set threshold value continuously appears on the transition zone due to uneven stress distribution or unreasonable structural design, so that the high-pressure concentration phenomenon of the junction area is formed.

It can be understood that the high-elastic gel layer adopts foam with gradually changed density from edge to center, the edge is selected from high-density foam, and the foam gradually transits to medium-density foam and then to low-density foam inwards, which means foam with gradually lower density.

For example, high density polyurethane foam (density 65kg/m 3) was used at the edges, medium density polyurethane foam (density 50kg/m 3) was used in the middle transition zone, and low density slow rebound memory sponge (density 30kg/m 3) was used in the center zone.

It can be understood that the thigh area and the ischial area corresponding to the cushion are provided with high-elastic gel layers, the high-elastic gel inserts are distributed along the dot matrix distance of + -1-2 dot matrix in the row-column orthogonal direction by the central coordinates of the connecting bands, the color mark area is outwards expanded by 3-5 dot matrix distance to form a transition band, which is the connecting band part of the pointer to the thigh area and the ischial area edge in the cushion, and the integral adjustment scheme is to design the area as a layer of high-elastic gel layers so as to relieve pressure concentration. The specific method is that a high elastic gel small block insert is inserted into the central position of the connecting belt, wherein the central coordinate of the connecting belt is determined by a pressure heat map, extends to the positions of 1 to 2 lattice distances along the row and column directions, so that a key support area is formed. And simultaneously, the high-voltage area marked by the color is outwards expanded by 3 to 5 lattice distances to form a pressure buffer transition zone area. The material density of the high-elastic gel layer is gradually changed from the edge to the center, wherein the edge is provided with high-density foam to ensure supporting force, the high-density foam is gradually changed into medium density inwards, and then the high-density foam is changed into low-density foam to realize soft transition and improve sitting comfort.

For example, in a cushion composed of a pressure-sensitive layer having a 50×50 lattice and a 5mm adjacent-dot pitch, the center coordinates of the joint strip are located in the 25 th row and the 25 th column, and the high-elastic gel inserts are inserted in the row and column directions in the ranges of the 23 rd to 27 th rows and the 23 rd to 27 th columns. The high pressure color region identified in the pressure heat map was expanded 25mm outward, i.e., from row 20 to row 30, column 20 to column 30, as the transition zone range. In the range, the high-elastic gel layer adopts foam with gradually changed density, gradually transits from the high density of the outer edge to the low-density foam, realizes buffer support with moderate hardness, reduces local pressure concentration, and improves the overall comfort and protection effect.

In some examples, the pressure sensing layer is a pressure lattice of M rows and N columns, the corresponding pressure heat map is an identification color dot map presenting a plurality of identification colors in the pressure lattice of M rows and N columns, where m=n=50k, and k is a positive integer, a distance between corresponding positions of every two adjacent sensing points on the cushion in the pressure sensing layer lattice is 5-10mm, and in step S510, determining that the cushion has a high-pressure state of a strand-sitting-tail intersection zone according to the total pressure heat map corresponding to the total pressure data, including:

In the total pressure heat map corresponding to the detected total pressure data, a high-pressure color identification area appears continuously for multiple frames in a crossing area from 20M/50 to 22M/50 row to 23N/50 to 27N/50 column at the junction of a thigh area and a ischial area, a secondary high-pressure color identification area appears in a crossing area from 40M/50 to 42M/50 row to 20N/50 to 24N/50 column or a high-pressure color identification area appears continuously for multiple frames, the secondary high-pressure color identification area and the high-pressure color identification area appear in color gradual change characteristics, a high-pressure state of a thigh-seat-tail junction zone appears in a cushion is determined, wherein the secondary high-pressure color identification area and the high-pressure color identification area appear in color gradual change characteristics, namely, the identification color corresponding to a high-pressure area is changed into the identification color corresponding to a low-pressure area from the ischial area to the coccyx area, and the identification color corresponding to the high-pressure area is changed into the identification color corresponding to the low-pressure area from the high-pressure area.

For example, on a cushion corresponding to a pressure sensing layer with 50X 50 lattice and 5mm adjacent lattice spacing, the high-voltage color identification area is large in the continuous 30 frames in the crossing area from the 20 th row to the 22 nd row and from the 23 rd column to the 27 th column at the junction of the thigh area and the ischial area, the low-voltage color identification area is formed in the crossing area from the 40 th row to the 42 th row and from the 20 th column to the 24 th column at the junction of the ischial area and the coccyx area, or the high-voltage color identification area is formed in the continuous 30 frames, the formed low-voltage color identification area and the high-voltage color identification area show color gradual change characteristics, and the high-voltage state of the strand-sitting-coccyx intersection zone of the cushion is determined. Fig. 13 is a diagram showing a part of a high-pressure state of a thigh zone, a ischium zone and a coccyx zone in a pressure heat map corresponding to overall pressure data, wherein a part consisting of red and dark red areas in the diagram is a high-pressure color identification zone, a part consisting of orange and red is a secondary high-pressure color identification zone, and a part consisting of cyan and yellow-green is a medium-pressure color identification zone.
