Referring to fig. 1 to 2, acleaning apparatus 100 according to an embodiment of the present invention is used to move along a surface of an object to be cleaned to clean the surface of the object (e.g., a floor). The following describes the structure of thecleaning device 100 in the present application, taking thecleaning device 100 as an example of a sweeping and mopping integrated robot. The present embodiment is described as an example, and the technical scope of the present application is not limited thereto. It is understood that in other embodiments, thecleaning device 100 may also be embodied as other devices, such as a floor mopping robot, and the like, without limitation.

Thecleaning device 100 includes amain housing 20, adriving wheel assembly 40 mounted on themain housing 20, a dust suction assembly, and a power supply assembly (not shown). Thedriving wheel assembly 40 is used for driving thecleaning device 100 to move on the surface of an object, the dust collection assembly is used for adsorbing dust and sundries on the surface of the object, and the power supply assembly is used for providing working electric energy for thedriving wheel assembly 40 and the dust collection assembly. It is to be understood that the specific configuration of thecleaning device 100 is not limited and may be set as desired.

Themain housing 20 includes alower housing 21, anupper housing 22 and abottom cover 23, thelower housing 21 includes a lower housingmain body 212 and a drivinghousing 214, the lower housingmain body 212 and theupper housing 22 are mutually fastened in a second direction (i.e. Y direction in fig. 1), thebottom cover 23 is coupled to one side of the lower housingmain body 212 far away from theupper housing 22, the drivinghousing 214 is disposed on one side of the lower housingmain body 212 facing theupper housing 22 and is integrally formed with the lower housingmain body 212, and the drivinghousing 214 is enclosed to form a drivingaccommodating cavity 2141 for accommodating thedriving wheel assembly 40. The drivingaccommodating cavity 2141 includes a first open end and a second open end that are opposite to each other in the second direction and are communicated with each other, and the first open end is located at a side of the drivingaccommodating cavity 2141 facing theupper shell 22, and the second open end is located at a side of the drivingaccommodating cavity 2141 away from theupper shell 22.

So, compare in the drive wheel subassembly among the prior art accommodate in the shell withinferior valve 21 independent setting, drive casing 214 in this application forms with inferior valvemain part 212 integrated into one piece, consequently can withdrive wheel subassembly 40 direct mount ininferior valve 21, and need not additionally to set up the cladding in the outer shell ofdrive wheel subassembly 40 to save part quantity and arranged the space, improved assembly efficiency simultaneously.

Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a driving wheel unit according to an embodiment of the present invention; fig. 4 shows an exploded view of a drive wheel assembly in an embodiment of the invention.

In some embodiments, thedriving wheel assembly 40 includes adriving wheel unit 41, and thedriving wheel unit 41 is received in the drivingaccommodating cavity 2141 from the first open end along the second direction. Thedriving wheel unit 41 comprises areduction gearbox 412, adriving wheel 414 and a drivingmotor 416, wherein thereduction gearbox 412 is provided with an input end and an output end, the drivingmotor 416 is arranged on thereduction gearbox 412 and is in transmission connection with the input end of thereduction gearbox 412, and thedriving wheel 414 is arranged on thereduction gearbox 412 and is in transmission connection with the output end of thereduction gearbox 412. Thus, the drivingmotor 416 is drivingly connected to thedriving wheel 414 through thereduction box 412, and the drivingmotor 416 drives thedriving wheel 414 to rotate by means of thereduction box 412 to drive thecleaning device 100 to move.

Specifically, thereduction gear box 412 includes afirst reduction housing 4121, asecond reduction housing 4123, and a reduction gear set. Thefirst deceleration housing 4121 and thesecond deceleration housing 4123 are engaged with each other in the first direction (i.e., the X direction in fig. 1) to form a deceleration accommodating chamber. One side of thesecond decelerating housing 4123 away from thefirst decelerating housing 4121 is provided with a first limiting space and a second limiting space which are arranged at intervals in a third direction (i.e., Z direction in fig. 1) perpendicular to the second direction and the first direction, the first limiting space is used for limiting thedriving wheel 414, the second limiting space is used for limiting the drivingmotor 416, and the second limiting space is located in front of the first limiting space in the advancing direction (i.e., F direction in fig. 1) of thecleaning apparatus 100. The speed reduction gear set is accommodated in the speed reduction accommodating cavity, the output end of the speed reduction gear set extends into the first limiting space, and the input end of the speed reduction gear set extends into the second limiting space.

Thedriving wheel 414 is limited in the first limit space of thereduction box 412 along the first direction, the axial direction of thedriving wheel 414 extends along the second direction, and thedriving wheel 414 is in transmission connection with the output end of the reduction gear set. The drivingmotor 416 is limited in the second limiting space of thereduction gearbox 412 along the first direction, the axis direction of the drivingmotor 416 extends along the second direction, and the output shaft of the drivingmotor 416 is in transmission connection with the input end of the reduction gear set.

As such, the drivingmotor 416 is located on one side in the radial direction of thedriving wheel 414 and is disposed at an interval from thedriving wheel 414 in the third direction, the axial direction of the drivingmotor 416 is parallel to the axial direction of thedriving wheel 414, and the drivingmotor 416 is located in front of thedriving wheel 414 in the forward direction of thecleaning apparatus 100. The second direction, the first direction and the third direction are pairwise vertical.

Compared with the prior art, in which the drivingmotor 416 is located behind thedriving wheel 414 in the advancing direction of thecleaning device 100, the drivingmotor 416 in the present application is located in front of thedriving wheel 414 in the advancing direction of thecleaning device 100, so that the side of thedriving wheel 414 facing the drivingmotor 416 has a larger friction force with the floor under the pressure of the drivingmotor 416, and therefore, thedriving wheel 414 has a better obstacle crossing capability when facing a front obstacle during the advancing process of thecleaning device 100, thereby further improving the performance of thecleaning device 100.

Further, the radial dimension of thedriving wheel 414 is larger than that of the drivingmotor 416, and thedriving wheel 414 protrudes toward thelower case 21 in the first direction, so that a side of thedriving wheel 414 facing the drivingmotor 416 forms an accommodating space into which a portion of the brush roll assembly (or other mechanism located in front of thedriving wheel assembly 40 in the advancing direction of the cleaning apparatus 100) can protrude, the advancing direction of thecleaning apparatus 100 being the same as the direction directed toward the brush roll assembly by thedriving wheel 414.

As such, thecleaning apparatus 100 of the present application utilizes the size difference between the drivingmotor 416 and thedriving wheel 414 in the second direction to accommodate the rolling brush assembly located in front of thedriving wheel assembly 40 in the advancing direction of thecleaning apparatus 100, so that the overall structure of thecleaning apparatus 100 is more compact, and the volume of the rolling brush assembly or other mechanisms can be further increased without changing the overall volume of thecleaning apparatus 100. In the prior art, since thedriving wheel 414 is located in front of the drivingmotor 416 in the forward direction of thecleaning apparatus 100, thedriving wheel 414 occupies a space in the second direction, so that the components having a large space occupation, such as the brush roller assembly, can be located only on one side of thedriving wheel assembly 40 in the third direction, thereby increasing the size of thecleaning apparatus 100 in the second direction.

It is understood that the forward direction of thecleaning device 100 in this application refers to the direction of movement of the cleaning device during normal sweeping. And when thecleaning apparatus 100 touches an obstacle, the cleaning apparatus moves backward in a direction opposite to the forward direction to avoid the obstacle.

In some embodiments, thedrive wheel assembly 40 further includes arotating shaft 42. The central axis of therotating shaft 42 extends along the first direction, one end of therotating shaft 42 is coupled to the cavity wall of the drivingaccommodating cavity 2141, the other end of therotating shaft 42 passes through thereduction gearbox 412 along the first direction and is coupled to the cavity wall of the drivingaccommodating cavity 2141, and thereduction gearbox 412 can swing around the rotatingshaft 42 as a rotating shaft under the action of external force so as to extend out of thelower shell 21 or retract into themain shell 20 in the second direction. In this way, thedriving wheel unit 41 can automatically swing under the action of external force to adapt to different working conditions.

Preferably, therotation shaft 42 is located in an accommodating space formed between thedriving wheel 414 and the driving motor 416 (i.e., on a side of thedriving wheel 414 facing the driving motor 416) in the advancing direction of thecleaning apparatus 100, and therotation shaft 42 is located below the drivingmotor 416 in a direction in which thedriving wheel 414 protrudes out of thelower case 21.

In this way, compared to the prior art in which therotating shaft 42 is located on the side of the drivingmotor 416 away from thedriving wheel 414, the maximum rotating radius of thedriving wheel unit 41 of the present application is the maximum distance between the outer circumferential surface of thedriving wheel 414 and therotating shaft 42, and this distance is much smaller than the rotating radius of the prior art driving wheel unit (the sum of the outer diameter of the drivingmotor 416 and the outer diameter of the driving wheel 414), so that the occupied space is effectively reduced, the arrangement of the parts in thecleaning apparatus 100 is more compact, and the volume of thecleaning apparatus 100 can be further reduced.

In some embodiments, thedriving wheel assembly 40 further includes an elastic member 43 (e.g., a spring), one end of theelastic member 43 is coupled to a side of thereduction gear box 412 away from thelower case 21 and is located at an end of thereduction gear box 412 where the drivingmotor 416 is provided, and the other end of theelastic member 43 extends obliquely in the third direction to be coupled to the driving housing 24. Theelastic member 43 is used to apply a force to thereduction gear box 412 away from theupper case 22 so that thedriving wheel 414 has a certain ground contact force to maintain sufficient contact with the surface of the object.

Because the drive assembly of this application does not set up solitary shell, compare in prior art before parts such as reducinggear box 412 installelastic component 43 from bottom to top to the shell in,elastic component 43 in this application can install along the second direction from top to bottom alone installation behindmain casing body 20 atdrive wheel unit 41, consequently makeselastic component 43's installation more convenient, has effectively improved production efficiency.

Fig. 5 is a schematic view illustrating installation of a ground disconnect switch according to an embodiment of the present invention, in conjunction with fig. 5 to 8; fig. 6 shows an assembly schematic of a ground disconnect switch of an embodiment of the present invention; figure 7 shows a schematic view of the installation of a ground disconnect switch in accordance with an embodiment of the present invention; fig. 8 shows an assembly schematic of a ground disconnect switch in accordance with an embodiment of the present invention.

In some embodiments, thedrive wheel assembly 40 also includes a ground-off switch 44 for detecting the position of thedrive wheel 414. The driving housing 24 includes a switch accommodating cavity 2143, the switch accommodating cavity 2143 is located at a side of thedrive accommodating cavity 2141 close to the edge of themain housing 20 in the first direction and communicates with thedrive accommodating cavity 2141, theground switch 44 is mounted in the switch accommodating cavity 2143 in the first direction and located at a side of thedriving wheel 414 in the axial direction, and theground switch 44 has aspring piece 441 that can be compressed. Thedriving wheel unit 41 includes atrigger 4125 for abutting against theelastic piece 441 of theground switch 44, and thetrigger 4125 is protruded from one side of thereduction box 412 in the first direction.

When thecleaning device 100 is supported on the object surface, thedriving wheel unit 41 is supported by the object surface and located at a first position away from thefloor switch 44, and thetrigger 4125 is separated from thefloor switch 44, the drivingmotor 416 can normally operate to drive thedriving wheel 414 to rotate.

When thecleaning device 100 is completely removed from the surface of the object (e.g., when the cleaning device is completely lifted off the surface of the object), the support from the surface of the object under thedriving wheel 414 is lost, so that thereduction gearbox 412 swings down around the rotatingshaft 42 to the second position where theground switch 44 is triggered, thetrigger 4125 compresses theelastic piece 441 on theground switch 44 to trigger theground switch 44, and the micro switch sends a signal to control the drivingmotor 416 to stop working, thereby avoiding the idle-running idle-work state of thedriving wheel 414 to save electric energy.

In this way, compared to the prior art in which theground switch 44 is located above thedriving wheel 414 in the radial direction, theground switch 44 of the present application is located in the axial direction of thedriving wheel 414 and is separately accommodated in the switch accommodating cavity 2143 which is independent from thedrive accommodating cavity 2141, so that while the installation manner of theground switch 44 is simplified, dust and foreign objects on thedriving wheel 414 can be effectively prevented from entering other areas in themain housing 20 through the switch accommodating cavity 2143 to cause damage to other components. However, in the prior art, since the switch receiving cavity 2143 is generally located above thedrive receiving cavity 2141 to communicate with other regions in themain housing 20, dust and foreign materials on thedriving wheel 414 may enter other regions in themain housing 20 through the switch receiving cavity 2143 to damage other components. In addition, thetrigger 4125 can limit the position of thedriving wheel assembly 40, and when thecleaning device 100 is completely away from the surface of the object, thetrigger 4125 can prevent thedriving wheel assembly 40 from further swinging downward without providing an additional limiting member. In the prior art, theground switch 44 is located above thedriving wheel 414 in the radial direction, and therefore cannot function as a limit.

Preferably, in some embodiments, the axial dimension of thedrive motor 416 is greater than the axial dimension of thedrive wheel 414, such that one end of thedrive motor 416 in the first direction protrudes beyond thedrive wheel 414. Theground disconnect switch 44 is located at one end of thedrive wheel 414 in the first direction, on the side of the end of thedrive motor 416 that protrudes beyond thedrive wheel 416. In this way, theground switch 44 is provided to fully utilize the height difference between the drivingmotor 416 and thedriving wheel 414 in the second direction, so that an additional installation space for theground switch 44 is not required.

As shown in fig. 5 and 6, particularly in some embodiments, thecleaning apparatus 100 includes twopositioning posts 60, a switch mounting plate 70, and alongitudinal fastener 80. The twopositioning columns 60 are arranged at intervals in the third direction, the central axis of eachpositioning column 60 extends along the first direction, one end of eachpositioning column 60 is fixedly connected to the cavity wall of the switch accommodating cavity 2143, and the other end of eachpositioning column 60 penetrates through theground switch 44 along the first direction. The switch mounting plate 70 is abutted against the side of theground switch 44 close to the second switch end along the second direction, and thelongitudinal fastener 80 is inserted into the cavity wall of the switch accommodating cavity 2143 through the switch mounting plate 70 along the second direction and is in threaded connection with the cavity wall of the switch accommodating cavity 2143.

In this manner, thepositioning post 60, thelongitudinal fastener 80, and the switch mounting plate 70 cooperate to securely fix thegrounding switch 44 in the switch receiving cavity 2143. Further, since thefloor switch 44 is fixed in the second direction from the outside by thelongitudinal fastener 80, the efficiency of attaching and detaching thefloor switch 44 is improved.

As shown in fig. 7 and 8, particularly in other embodiments, thecleaning apparatus 100 includes apositioning post 60 and atransverse fastener 90. The central axis of thepositioning column 60 extends along the first direction, one end of thepositioning column 60 is fixedly connected to the cavity wall of the switch accommodating cavity 2143, and the other end of thepositioning column 60 penetrates through theground switch 44 along the first direction. Thetransverse fastening member 90 is spaced from thepositioning column 60 in the third direction, a central axis of thetransverse fastening member 90 extends in the first direction, and thetransverse fastening member 90 is inserted into the cavity wall of the switch accommodating cavity 2143 through theground switch 44 in the first direction. In this manner, thepositioning post 60 and thelateral fastener 90 cooperate to securely fix theground switch 44 in the switch receiving cavity 2143.

Referring to fig. 9 to fig. 11, fig. 9 is a schematic diagram of a trace according to an embodiment of the invention; FIG. 10 is a trace diagram illustrating another angle according to an embodiment of the present invention; fig. 11 shows a schematic structural diagram of a drive housing according to an embodiment of the present invention.

In some embodiments, to enable electrical connection of thedrive motor 416 and theground disconnect switch 44 to external control structures, thedrive wheel assembly 40 further includes adrive motor wire 45 and a grounddisconnect switch wire 46.

In order to guide and limit the drivingmotor line 45 and the ground-off switch line 46, thereduction box 412 is provided with a reduction box motor routing channel, one side of the driving shell 24 of themain shell 20, which is provided with the drivingaccommodating cavity 2141, is provided with a main shell motor routing channel and a switch routing channel, and the main shell motor routing channel is communicated with the reduction box motor routing channel. One end of the drivingmotor line 45 is electrically connected to one axial end of the drivingmotor 416, and the other end of the drivingmotor line 45 sequentially penetrates through the reduction gearbox motor wiring channel and the main casing motor wiring channel to be connected with an external control structure. One end of theground switch wire 46 is electrically connected to theground switch 44, and the other end of theground switch wire 46 passes through the switch wiring path and the partial main housing motor wiring path to be electrically connected to the external control structure.

Therefore, the drivingmotor line 45 and theground switch 44 are independently wired, the wiring line is simple, and the wiring efficiency is improved.

Specifically, thedriving wheel assembly 40 includes a plurality of reduction gearbox routing clips 47, the plurality of reduction gearbox routing clips 47 are sequentially arranged on one side of thereduction gearbox 412 facing the second open end along the first direction, each reductiongearbox routing clip 47 includes reduction gearbox routing clamping portions arranged at intervals in the direction perpendicular to the first direction, two reduction gearbox routing clamping portions define and form a reduction gearbox routing gap, and a plurality of reduction gearbox routing gaps are mutually communicated to jointly form a reduction gearbox motor routing channel. The gearbox motor routing channel is located on one side of thegearbox 412 facing the second open end, is located on one side of therotating shaft 42 in the radial direction, and is substantially parallel to the extending direction of therotating shaft 42.

Because the rotatingshaft 42 is located between thedriving wheel 414 and the drivingmotor 416, and the reduction gearbox motor wiring channel is arranged adjacent to therotating shaft 42, when thereduction gearbox 412 swings around the rotatingshaft 42, the drivingmotor wire 45 penetrating the reduction gearbox motor wiring channel cannot be pulled, and therefore the drivingmotor wire 45 is prevented from being broken. Compared with the driving motor wire in the prior art, the driving motor wire is bent for 180 degrees after extending along the axial direction of the drivingmotor 416, the wiring line in the application is simpler, and therefore the assembly of thedriving wheel assembly 40 is more convenient.

The main shell motor wiring channel comprises a first motor wiring section, a second motor wiring section and a third motor wiring section. One end of the first motor route segment is communicated with the reduction gearbox motor route channel, and the other end of the first motor route segment extends towards the direction far away from the drivingmotor 416 along the third direction. One end of the second motor route segment is communicated with the first motor route segment, and the other end of the second motor route segment extends towards the first opening end along the second direction. One end of the third motor route segment is communicated with the second motor route segment, and the other end of the third motor route segment extends in a direction away from thedriving wheel 414 along the third direction.

Specifically, themain housing 20 includes at least two motor routing clips 25, the at least two motor routing clips 25 are sequentially arranged on the outer sidewall of the driving housing 24 close to one side of the ground-off switch 44 in the first direction along the third direction, eachmotor routing clip 25 has a first housing routing gap extending along the third direction, and the at least two first housing routing gaps are communicated with each other to form a first motor routing segment.

Themain housing 20 includes a motortrace limiting element 26, the motortrace limiting element 26 is disposed at an outer sidewall of the driving housing 24 (i.e. an outer wall of the driving accommodating cavity) along the first direction at an interval, and is located at a side of the driving housing 24 where the switch accommodating cavity 2143 is disposed. Amotor wiring groove 261 extending along the second direction is formed on one side of the motorwiring limiting piece 26 away from the driving shell 24 to form a second motor wiring segment, and a third motor wiring segment is formed between the motorwiring limiting piece 26 and the driving shell 24.

Thus, the drivingmotor wire 45 extends from one end of the drivingmotor 416 to the other end of the drivingmotor 416 along the first direction under the guidance of the gearbox motor routing channel, then bends into the first motor route segment and extends along the third direction towards the direction away from the drivingmotor 416 under the guidance of the first motor route segment, then bends into the second motor route segment and extends along the second direction towards the direction of the first opening end under the guidance of the second motor route segment, and finally bends into the third motor route segment and extends along the third direction towards the direction away from thedriving wheel 414 under the guidance of the third motor route segment.

The switch routing channel includes a first switch routing segment and a second switch routing segment, the first switch routing segment extends along the second direction, one end of the second switch routing segment is communicated with the first switch routing segment, and the other end of the second switch routing segment extends along the third direction towards the direction away from thedriving wheel 414 until the third motor routing segment is communicated with the housing motor routing channel.

Specifically, themain housing 20 includes a switchtrace limiting element 27, and the switchtrace limiting element 27 is disposed at an interval on an outer sidewall (i.e., an outer wall of the driving accommodating cavity) of one side of the driving housing 24 close to theground switch 44 along the first direction, and is located on one side of the accommodating cavity of theground switch 44 facing the first switch end in the second direction. One side of the switchtrace limiting element 27 away from the drivingaccommodating cavity 2141 is formed with aswitch trace groove 272 extending along the second direction to form a first switch trace segment. A second switch trace segment is formed between the switchtrace limiting piece 27 and the outer sidewall of the driving shell 24. Preferably, the motortrace limiting piece 26 and the switchtrace limiting piece 27 are arranged side by side in the third direction and are formed by integral molding.

In this manner, one end of theground switch wire 46 is connected to theground switch 44, and the other end of theground switch wire 46 extends in the second direction toward the first open end under the guidance of the first switch route segment, then bends into the second switch route segment, and extends in the third direction toward thedrive motor 416 under the guidance of the second switch route segment until entering the third motor route segment to merge with thedrive motor wire 45.

In summary, the drivingmotor line 45 and theground switch line 46 are respectively led out from the drivingmotor 416 and theground switch 44, and then independently extend for a distance to be converged, so that the wiring line is simple, the problem of line breakage caused by an excessively large bending angle is avoided, and the assembly steps are simplified. It is understood that the routing manner of the drivingmotor line 45 and theground switch line 46 is not limited thereto, and in other embodiments, other routing manners may be provided to meet different requirements.

In the above-mentioneddriving wheel assembly 40 and thecleaning device 100, the driving housing 24 of thedriving wheel assembly 40 is directly integrated on themain housing 20, thereby simplifying the structure of thecleaning device 100 and optimizing the installation manner. Moreover, since the drivingmotor 416 is located in front of thedriving wheel 414 in the forward direction of thecleaning apparatus 100, the obstacle avoidance performance is better, and the components such as the rolling brush assembly can be accommodated by utilizing the radial dimension difference between thedriving wheel 414 and the drivingmotor 416, so that the internal structure of thecleaning apparatus 100 is more compact. Further, since the ground-off switch 44 is provided on one side in the axial direction of thedrive wheel assembly 40, it is possible to prevent dust and foreign matter on thedrive wheel 414 from entering the inside of themain housing 20. In addition, the wiring mode of the drivingmotor line 45 connected with the drivingmotor 416 and theground switch line 46 connected with theground switch 44 is simpler, and the drivingmotor line 45 and theground switch line 46 are effectively prevented from being broken.

The driving housing 24 in fig. 4 to 8 is only used to reflect the matching relationship between the driving housing 24 and thedriving wheel assembly 40, and actually, the driving housing 24 is always integrally formed with thebottom case 21.
