It will be appreciated by those skilled in the art that the configuration shown in FIG. 7 is not limiting of the in-vehicle air delivery system and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
As shown in fig. 7, an operating system, a data storage module, a network communication module, a user interface module, and a vehicle-mounted air supply system control program may be included in the memory 1005 as one type of storage medium. In the vehicle-mounted air supply system shown in fig. 7, the network interface 1004 is mainly used for data communication with other devices, the user interface 1003 is mainly used for data interaction with a user, and the processor 1001 and the memory 1005 in the vehicle-mounted air supply system can be arranged in the vehicle-mounted air supply system, and the vehicle-mounted air supply system calls the vehicle-mounted air supply system control program stored in the memory 1005 through the processor 1001 and executes the control method of the vehicle-mounted air supply system provided by the embodiment of the invention.
In the embodiment of the invention, the vehicle-mounted air supply system comprises a vehicle-mounted air conditioner and an air blower, wherein the vehicle-mounted air conditioner comprises an air conditioner shell, and the air blower, the refrigerating module and the heating module which are all arranged on the air conditioner shell, and the related structure and principle of the vehicle-mounted air conditioner belong to the mature prior art, so that the description is not repeated here.
Referring to fig. 5 and 6, in an embodiment of the present invention, a vehicle body is provided with a passenger compartment and a window opening communicating with the passenger compartment, and a blower is provided at the window opening and is capable of supplying air to the outside of the vehicle. The window opening 21 refers to a window that can be opened movably on the vehicle body, and the window opening 21 includes, but is not limited to, a window of a front door, a window of a rear door, a rear window at a front end of a rear hopper, a sunroof at a roof, and the like, taking a pick-up car type as an example. Referring to fig. 1 to 3, in particular, the blower includes:
A shell 11 provided with an air duct 11, an air inlet 12 and an air outlet 13 both communicated with the air duct 11, an air outlet 13 provided with a slit-shaped air nozzle 131, and an air flow can form a coanda effect when being blown out through the air nozzle 131, and
The fan 14 comprises a driving piece and a wind wheel connected with the driving piece in a driving way, and the wind wheel is at least partially arranged in the air duct 11.
Therefore, the air volume of the blower can be increased by utilizing the air volume multiplication effect of the coanda effect, and the exchange rate of air inside and outside the passenger cabin can be increased. Secondly, install in door window opening department through the forced draught blower of no flabellum structure, can reduce and avoid the forced draught blower to the negative influence that door window opening department field of vision led to the fact sheltering from even to the forced draught blower can not obviously influence the original molding of vehicle, is favorable to promoting the clean and tidy aesthetic property of vehicle. Of course, in other embodiments, the blower may be configured as a conventional fan structure with blades, or a conventional blower structure.
In order to enrich the functions of the blower, please refer to fig. 1 to 3, in an embodiment, the blower further includes a main control board disposed on the housing 11, the air nozzle 131 includes two opposite first air nozzle sections 131a, the two first air nozzle sections 131a are formed with an air supply cavity 132 at intervals, the blower 14 is provided with at least two fans 14, the at least two fans 14 are respectively connected to the two first air nozzle sections 131a, and the air output can be independently adjusted under the control of the main control board, so that the coanda effect degrees formed on the two first air nozzle sections 131a are the same or different.
In this way, by adjusting the air output amounts of the two fans 14 to be the same or different, the coanda effect degree formed on the two first nozzle segments 131a can be the same or different, so that the direction of the air flow flowing through the air supply chamber 132 is changed. Specifically, assuming that the air output of the two fans 14 is the same at the beginning, the coanda effect (including the airflow expansion trend and the air volume multiplication effect) on the two first air nozzle segments 131a is the same, and the airflow is not biased to supply air outwards along the axis of the air supply cavity 132 at this time, when the air output of one fan 14 is reduced and the other fan 14 is kept unchanged, the coanda effect on the first air nozzle segment 131a corresponding to one fan 14 is weakened, and the coanda effect on the first air nozzle segment 131a corresponding to the other fan 14 is kept unchanged, so that the air supply direction of the airflow in the air supply cavity 132 is biased towards the direction close to the fan 14, that is, biased towards the side close to the reduction of the air output of the fan 14, thereby realizing the function of automatically adjusting the air supply direction (that is, adjusting the air direction) of the fan 10 and improving the convenience in use of the fan 10. The outward air flow means that the air flow is sent from the air inlet side of the air supply chamber 132 to the air outlet side of the air supply chamber 132.
In the embodiment of the present invention, alternatively, two first tuyere sections 131a are respectively disposed at the left and right sides of the blower 10, so that the air flow blown out from the air supply chamber 132 can be deflected left and right, that is, the air of the blower 10 can be adjusted left and right. Of course, in some embodiments, two first tuyere sections 131a may be provided on both upper and lower sides of the blower 10, respectively, to achieve up-and-down adjustment of the wind direction of the blower 10. In other embodiments, the air nozzle 131 further includes two opposite second air nozzle segments 131b, the second air nozzle segments 131b are communicated between the two first air nozzle segments 131a, at least four fans 14 are correspondingly disposed, and at least four fans 14 are correspondingly connected with the two first air nozzle segments 131a and the two second air nozzle segments 131b, so that up-down wind direction adjustment, left-right wind direction adjustment and more complex and variable wind direction adjustment of the air blower 10 can be realized.
Specifically, there are various ways to realize the air output adjustment of the fan 14, for example, in an embodiment, the main control board adjusts the rotation speed of the fan 14 to realize the air output adjustment, that is, the air output is large when the rotation speed is high and the air output is small when the rotation speed is low, and the control logic is simple and easy to realize. That is, the air direction of the air flow in the air blowing chamber 132 is changed by the difference in the rotational speeds of the two fans 14, so that the air direction of the blower 10 is adjusted. Of course, in some embodiments, the rotation speed of the fan 14 may be kept unchanged, the air outlet side of the fan 14 is provided with a movable air door electrically connected with a main control board, and the main control board adjusts the opening degree of the movable air door to realize the adjustment of the air outlet. In other embodiments, the air output can be adjusted by adjusting the rotation speed of the fan 14 and the opening degree of the movable air door simultaneously.
It will be appreciated that when the air output of the fan 14 is determined by the opening degree of the movable damper, the fan 14 may be provided with only one and the air output flowing to the two first nozzle segments 131a may be distributed by the movable damper. For example, in another embodiment, the air duct 11 includes a first branch and a second branch both connected to the air outlet side of the fan 14, the first branch and the second branch are respectively connected to two first tuyere segments 131a, and the movable damper can move between the first branch and the second branch to partially block the inlet of the first branch and/or the inlet of the second branch. In this way, the air output of one fan 14 is equally or unevenly distributed to the first branch and the second branch under the movement of the movable air door, so that the coanda effect formed by the two first air nozzle sections 131a is the same or different. Of course, in other embodiments, two movable air doors may be provided and respectively rotatably disposed in the first branch and the second branch, where the two movable air doors may independently adjust the cross-sectional areas of the first branch and the second branch.
It should be noted that the main control board is not required to be arranged on the blower, and the rotation speed adjustment of the blower or the opening degree adjustment of the movable air door can be completed through a control chip of the vehicle-mounted central control host or the vehicle-mounted air conditioner, namely, the control function of the vehicle-mounted air supply system is integrated on the vehicle-mounted central control host or the vehicle-mounted air conditioner, so that the structure of the blower is simplified. Specifically, the blower and the vehicle-mounted central control host (or the vehicle-mounted air conditioner) can be connected by wire communication or wireless communication, and the wireless communication connection comprises but is not limited to infrared communication, bluetooth communication, wi-Fi (WIRELESS FIDELITY ) communication, 4G/5G mobile communication and the like. It should be noted that the control mode of the fan is not limited to PWM control, and lin, CAN, voltage control, or the like may be used.
Of course, the wind direction of the blower may be adjusted by a mechanical rotation structure, for example, a mechanical rotation structure for realizing a head shaking function on a general fan with blades. It can be appreciated that the technical scheme of the invention can be realized through simple air volume adjustment, and compared with the scheme adopting a mechanical rotating structure, the invention has simpler structure and more stable and reliable operation.
In order to improve the strength and stability of the air flow in the air supply cavity 132, referring to fig. 1 to 3, in an embodiment, the air outlet 13 is configured as an annular structure and encloses the air supply cavity 132, the air nozzle 131 further includes two opposite second air nozzle segments 131b, and the air flow can form a coanda effect when being blown out through the second air nozzle segments 131b, and the second air nozzle segments 131b are communicated between the two first air nozzle segments 131 a. Thus, the periphery of the air supply cavity 132 is affected by the coanda effect, but the air flow formed in the air supply cavity has stronger air volume multiplication effect, and the air flow is more condensed and the air supply direction is more stable. In addition, the annular structure can improve the structural strength of the air outlet 13, which is beneficial to prolonging the service life of the blower 10. Of course, in some embodiments, the air outlet 13 may be configured in a ring structure, but the second tuyere segment 131b is not provided, that is, the two first tuyere segments 131a are not connected but are fixed together only by a connecting bracket. In other embodiments, only one second tuyere segment 131b is provided and is connected between the two first tuyere segments 131a, that is, the air outlet 13 has a U-shaped structure.
Referring to fig. 3, in an embodiment, the air outlet 13 is provided with a first air guiding wall 13a and a second air guiding wall 13b on a side facing the air supplying cavity 132, the first air guiding wall 13a and the second air guiding wall 13b are sequentially arranged along the air supplying direction of the air supplying cavity 132 and are formed with air nozzles 131 at intervals, and in the air supplying direction of the air supplying cavity 132, the second air guiding wall 13b extends obliquely toward a direction close to an axis of the air supplying cavity 132 (a center of the air supplying cavity 132) and then extends obliquely toward a direction far away from the axis of the air supplying cavity 132. In this way, the air in the air duct 11 has a tendency of approaching the axis of the air supply cavity 132 and separating from the axis of the air supply cavity 132 when flowing out through the air nozzle 131, that is, the wall attaching effect of the air flow on the second air guide wall 13b is improved, and the air volume multiplication effect of the whole air flow in the air supply cavity 132 is further improved. Of course, in other embodiments, the first air guiding wall 13a and the second air guiding wall 13b may be sequentially arranged along the air supply direction of the air supply cavity 132 and formed with air nozzles 131 at intervals, in the air supply direction of the air supply cavity 132, the first air guiding wall 13a extends obliquely in a direction close to the axis of the air supply cavity 132, and then extends obliquely in a direction away from the axis of the air supply cavity 132, and the second air guiding wall 13b extends obliquely in a direction away from the axis of the air supply cavity 132.
Referring to fig. 1 to 3, in an embodiment, two first tuyere sections 131a are respectively disposed at two opposite sides of the air outlet 13 in the length direction thereof, and two fans 14 are respectively disposed at two opposite sides of the air outlet 13 in the length direction thereof. Thus, the center of gravity of the blower 10 can be more adjacent to or fall on the center of gravity of the blower by the symmetrical distribution, and the height of the center of gravity of the blower can be reduced, thereby being beneficial to the use stability of the blower 10. Of course, in some embodiments, two first air nozzle segments 131a may be respectively disposed on opposite sides of the air outlet 13 in the width direction thereof, and two fans 14 may be respectively disposed on opposite sides of the air outlet 13 in the length direction thereof. In other embodiments, two fans 14 may be disposed on the same side of the air outlet 13.
In an embodiment, the air duct 11 includes a cylindrical tube section 11a, the wind wheel is configured as a centrifugal wind wheel and is disposed in the cylindrical tube section 11a, and the axis of the cylindrical tube section 11a and the axis of the centrifugal wind wheel both extend along the length direction of the air outlet 13. That is, the blower 14 is configured as a centrifugal blower 14. In this way, the blower 10 can be made more compact, thereby facilitating a compact design. In this embodiment, the air inlet 12 is optionally provided on the outer peripheral surface of the cylindrical tube section 11a and configured in a grid hole structure. Therefore, the path length of the air duct 11 between the air inlet 12 and the air outlet 13 can be shortened, and the air flow can flow in the air duct 11 more smoothly, so that the along-path loss of the air flow can be reduced. Secondly, the air inlet 12 of the grid hole structure can play a certain role in preventing dust, water and mosquitoes from entering. Of course, in some embodiments, it is also possible that the fan 14 is configured as an axial fan 14, a cross-flow fan 14, or a rotary fan 14. In other embodiments, the air inlet 12 may be provided on the end face of the cylindrical pipe section 11 a.
Referring to fig. 6, in order to facilitate the user to control the functions of the blower 10, in an embodiment, the blower 10 further includes a function key 15 disposed on the housing 11, and the function key 15 is electrically connected to the main control board. Specifically, the function key 15 may be a physical button or a touch panel, and the function key 15 may include a power switch, an air volume adjustment, a wind direction adjustment, an automatic wind swinging, and the like. Of course, in other embodiments, instead of providing the function keys 15 on the housing 11, a wireless transmission module (such as an infrared receiver or a bluetooth module) may be provided on the main control board, and a remote controller may be configured to implement remote function control of the blower 10.
In an embodiment, the blower 10 further includes a power interface disposed on the housing 11, and the power interface is electrically connected to the main control board. The power interface may include a direct current interface and an alternating current interface, such as a 12V power interface and a 220V power interface. In this way, the user can conveniently select a proper power supply to supply power to the blower 10 according to the actual situation. Optionally, in this embodiment, the blower is electrically connected to the vehicle power source, i.e. the vehicle power source supplies power to the blower to support its operation. Of course, in some embodiments, the blower 10 may also be provided with a battery compartment electrically connected to the main control board, and the battery compartment is used for installing a rechargeable battery or a dry battery.
Referring to fig. 5, in an embodiment, the vehicle body 20 includes a rear bucket (e.g. a truck-type cargo bucket), an opening of the rear bucket faces upward and is used for carrying cargo, the window opening 21 includes a rear window, the rear window is disposed on a front end surface of the rear bucket, and the air outlet 13 is configured in a ring structure and is disposed on an edge of the rear window. Specifically, alternatively, the inner contour dimension of the annular air outlet 13 is adapted to the opening dimension of the rear window, for example, equal to or slightly greater than the opening dimension of the rear window, so that the normal use function of the rear window is not affected, and the normal operation of the blower 10 is not affected. In this embodiment, the window glass on the rear window is configured to be removable or liftable, and the blower 10 is not limited to blowing air to the outside of the vehicle, but may also blow air to the inside of the vehicle (i.e., in the passenger compartment), and specifically may be adjusted according to design requirements.
It will be appreciated that for example, in the case of a pick-up car type, the front face of the rear hopper is generally adjacent to or against the rear end panel of the passenger compartment, and the rear hopper may be used not only for loading but also for user activity thereon, for example, the user may rest the vehicle on the river and sit on the rear hopper for fishing, so that the blower 10 provided at the rear window provides the user with a blowing function. Further alternatively, when the vehicle-mounted air supply system is turned on to adjust the temperature in the passenger compartment, for example, when the passenger compartment is refrigerated, the other window openings 21 are closed and only the rear window is reserved, and the air blower 10 on the rear window can send the cool air in the passenger compartment out of the vehicle, so that the air blowing refrigeration outside the vehicle is realized, and the use convenience of the air supply function outside the vehicle is improved.
Of course, the blower 10 may be mounted on any structure of the vehicle body 20 as an accessory for easy assembly and disassembly, for example, referring to fig. 5 and 6, in an embodiment, the blower 10 further includes a mounting member 16 fixed to the housing 11, and the mounting member 16 is detachably connected to an edge of the window opening 21. Specifically, alternatively, the mounting member 16 includes at least two straps 16, where the at least two straps 16 are respectively disposed on opposite sides of the blower 10, so that the blower 10 can be mounted by binding the straps 16 to the edges of the window opening 21, which is simple and convenient to operate and has a simple structure. Of course, in some embodiments, the mounting member 16 may further include a magnet, where the magnet can be absorbed on the sheet metal part at the edge of the window opening 21, or the mounting member 16 may include a clamping structure, where the edge of the window opening 21 is provided with a clamping hole, and the clamping structure can be clamped in the clamping hole.
The present invention also provides a control method of a vehicle-mounted air supply system for a vehicle, referring to fig. 8, in a first embodiment of the control method of a vehicle-mounted air supply system of the present invention, the control method of a vehicle-mounted air supply system includes step S10 and step S20.
Step S10, receiving an external opening signal.
Specifically, in the embodiment of the invention, the source of the external opening signal has various modes, for example, a user can operate a function key on the blower, operate a vehicle-mounted central control screen or input a voice command in the passenger cabin, or the user can send a remote command to the vehicle by using an APP or a small program on an intelligent mobile terminal such as a mobile phone, a tablet personal computer and the like so as to start the external air supply function of the vehicle-mounted air supply system, and the external opening signal can be generated. Of course, the user can also set the time for starting the reservation to start the off-vehicle air supply function at regular time.
It should be noted that, in an embodiment, an inductor is disposed at a window opening where the blower is located, and when the window glass on the window opening descends to a preset position, the inductor can generate an external opening signal. Specifically, the sensor may be a distance sensor, a proximity switch, a tact switch, or the like. It will be appreciated that if the window opening of the blower is opened, this represents that the user may wish to turn on the off-board blower function of the blower, and particularly, when the window opening of the blower is not normally opened, such as the rear window of a pick-up car type, the high probability of the window opening being opened means that the user has a need to turn on the off-board blower function.
The external opening signals generated in any mode can be received by the processor of the vehicle-mounted air supply system, and the vehicle-mounted air supply system can respond correspondingly according to different external opening signals, and the specific situation is shown below.
And S20, starting the air feeder.
Specifically, in the embodiment of the invention, only the blower can be independently started without starting the vehicle-mounted air conditioner, after the window opening where the blower is positioned is opened, the air flow formed by the blower can be sent out of the vehicle through the window opening, so that the most basic air supply function outside the vehicle is realized, and the vehicle-mounted air supply system enters the air supply mode outside the vehicle. Of course, the blower and the vehicle-mounted air conditioner may be turned on at the same time.
It should be noted that, the window opening may be opened manually by a user, for example, the user operates the vehicle-mounted central control screen to electrically lower the window glass on the window opening, or the window opening may be opened under the control of the external opening signal, that is, in this embodiment, optionally, after step S10, the vehicle-mounted air supply system control method further includes opening the window opening where the blower is located. Therefore, the blower and the window opening where the blower is positioned are controlled to be opened simultaneously, and the operation times of giving instructions by a user can be saved, so that the use convenience of the vehicle-mounted air supply system is improved.
According to the technical scheme, the air feeder is arranged at the opening of the vehicle window, and the external opening signal is sent to the vehicle-mounted air supply system so that the vehicle-mounted air supply system enters an external air supply mode (at least the air feeder is started), so that air flow can be blown out of the vehicle, the vehicle has an external air supply function, and a user outside the vehicle can feel more comfortable under the action of the air flow. In addition, if the vehicle-mounted air conditioner supplies cool air or warm air to the passenger cabin, the cool air or warm air in the passenger cabin can be blown to a user outside the vehicle under the drive of the air flow generated by the air feeder, so that the effect of the air supply function outside the vehicle is further improved. Thus, the use functions of the vehicle can be enriched and the user experience can be improved
It should be noted that, in this embodiment, the vehicle-mounted air supply system further includes a ventilation pipe, where the ventilation pipe can be installed on the blower or the window opening, so as to guide the air flow blown by the blower to an area farther from the vehicle, and thus, the flexibility and convenience of use of the vehicle-mounted air supply system can be further improved.
In a second embodiment of the present invention, based on the first embodiment of the present invention, after the step of turning on the blower, the vehicle-mounted air supply system control method further includes:
and step S30, starting the vehicle-mounted air conditioner.
Specifically, in the embodiment of the invention, the on-vehicle air conditioner can be started by only starting the blower of the on-vehicle air conditioner without synchronously starting the refrigerating module or the heating module, or can be synchronously started by starting the blower and the refrigerating module or synchronously starting the blower and the heating module, and the specific starting mode of the on-vehicle air conditioner is determined according to different external starting signals or user setting parameters. For example, in this embodiment, alternatively, the one-button start-up on-vehicle air supply system may be set to enter a default on-mode, that is, the air volume of the blower is controlled to be 50%, the air volume of the blower of the vehicle-mounted air conditioner is controlled to be 50%, the vehicle-mounted air conditioner is in an external circulation mode, and the window opening where the blower is located is opened, that is, the vehicle-mounted air conditioner does not enter a cooling mode or a heating mode in the default on-mode, and the blower simply utilizes the coanda effect at the air nozzle to send the air in the passenger compartment out of the vehicle. It will be appreciated that if the temperature in the passenger compartment is now lower than the outside air temperature, for example, if the passenger compartment has undergone a cooling process before the blower is turned on, the flow of air from the blower to the outside of the vehicle will have a certain cooling effect, but it is apparent that the cooling effect will not last long. Of course, in other embodiments, the function parameters corresponding to the default on mode may also be configured in other forms.
In a third embodiment of the present invention, based on the second embodiment of the above-mentioned vehicle-mounted air supply system control method, step S30 includes:
step 311, if the external power on signal is a cooling mode signal or a heating mode signal.
Specifically, the air conditioning mode signal includes a cooling mode signal and a heating mode signal. If the default opening mode cannot meet the user requirement, the user can adjust the functional parameters, such as air volume, temperature, wind direction angle, and the like, through a user interaction interface (including a functional key on the blower, a vehicle-mounted central control screen, a vehicle-mounted central control key, a mobile phone APP, and the like) or a voice control instruction. In this embodiment, optionally, options of "cooling mode" and "heating mode" may be provided, or the user-set temperature may be compared with the outside air temperature, and a corresponding air conditioning mode signal may be generated according to the comparison result. For example, assuming that the outside air temperature is 28 ℃, when the user sets the temperature to 16 ℃ (lower than the outside air temperature), it is determined that the user needs a cooling function, and a cooling mode signal is generated to control the vehicle-mounted air conditioner to enter a cooling mode, so that the blower and the cooling module of the vehicle-mounted air conditioner are synchronously started. The outside air temperature of the vehicle can be directly obtained through a temperature sensor on the vehicle body, and the local air temperature of the place where the vehicle is located can also be obtained through the Internet of things or the Internet.
Step S312, opening window openings where the blower is located, and closing the rest window openings.
Specifically, the rest window openings are closed, only the window opening where the blower is located is reserved, the leakage speed of cool air or warm air in the passenger cabin can be effectively reduced, and the cool air or warm air can be sent out of the vehicle through the blower more, so that good air supply cooling or heating effects outside the vehicle are achieved.
Step S313, controlling the vehicle-mounted air conditioner to enter a refrigerating mode or a heating mode.
In this embodiment, through forced draught blower and on-vehicle air conditioner cooperation, can send out the air conditioning or the heating air that produce on-vehicle air conditioner outside the car to the local space outside the car carries out air conditioning to can improve the travelling comfort and the convenience of outdoor activities. And utilize on-vehicle air conditioner to replace independent portable outdoor air conditioner, can save portable outdoor air conditioner's acquisition cost and maintenance cost, and self simple structure, the low in production cost of forced draught blower to the realization lets the user experience the effect of air conditioning function in the open air with lower cost. It should be noted that, in this embodiment, the vehicle-mounted air supply system may further include a ventilation pipe, and the ventilation pipe may be mounted on the blower or the window opening to guide the air flow blown by the blower to an area farther from the vehicle. After a user drives to camp, picnic or fishing places, cold air prepared by the vehicle-mounted air conditioner sequentially flows through the passenger cabin, the air blower and the ventilation pipe until the place where the user is located, and therefore the use flexibility and convenience of the vehicle-mounted air supply system can be further improved. Of course, ventilation ducts may also be used to further direct the air flow into the camp tent to regulate the temperature within the tent.
Optionally, in this embodiment, after step S311, step S30 further includes:
and step S314, controlling the vehicle-mounted air conditioner to enter an external circulation mode.
In this embodiment, the external circulation mode of the vehicle-mounted air conditioner means that the air inlet of the blower is communicated with the space outside the vehicle, that is, the air entering the blower of the vehicle-mounted air conditioner is the air from outside the vehicle, and the internal circulation mode of the vehicle-mounted air conditioner means that the air inlet of the blower is communicated with the space inside the vehicle, that is, the air entering the blower is the air from inside the passenger compartment. The vehicle-mounted air conditioner is adjusted to an external circulation mode, so that air flowing through the air blower and the air feeder is air from outside the vehicle, namely outdoor fresh air, and the external blowing effect of the vehicle can be improved. Moreover, it can be understood that the air in the passenger cabin is not clear due to the closed state, and can possibly carry harmful substances volatilized by the vehicle interior trim, and the risk of injury of the harmful volatile substances in the passenger cabin to a user can be reduced by adopting the external circulation mode. Of course, in other embodiments, the on-vehicle air conditioner may also be in an on-internal circulation mode. Since the external circulation mode and the internal circulation mode of the vehicle-mounted air conditioner are both mature prior art, the description thereof is omitted herein.
In a fourth embodiment of the present invention, based on the second embodiment of the above-mentioned vehicle-mounted air supply system control method, step S30 includes:
step S321, if the external power-on signal is a strong mode signal.
In this embodiment, shortcut options with multiple functional modes can be set on the user interface for the user to select, including but not limited to a natural wind mode, a strong mode, a gentle mode, a strongest refrigeration mode (i.e. Max AC), a wind swing mode, etc., and dedicated shortcut keys for operating these functional modes will generate corresponding different external opening signals. That is, the external opening signal includes various functional mode signals, such as a corresponding natural wind mode signal, a strong mode signal, a gentle mode signal, a most forced cooling mode signal, a swinging wind mode signal, and the like, and the vehicle-mounted air supply system controls the vehicle-mounted air conditioner and the blower to execute corresponding functional parameters after receiving different functional mode signals.
And S322, adjusting the air quantity of the blower and the blower of the vehicle-mounted air conditioner to the maximum value.
Specifically, in the present embodiment, the soft mode and the strong mode are only a single element of controlling the air volume, for example, the air volume of the blower is adjusted to the maximum, the air volume of the blower of the vehicle-mounted air conditioner is adjusted to the maximum, that is, the strong mode, and the air volume of the blower is adjusted to the moderate (for example, 20% to 40% of the air volume) to be the soft mode, regardless of whether the vehicle-mounted air conditioner is in the cooling or heating mode. In particular, the functional parameters of the soft mode are suitable for use with a blower in conjunction with a tent so that a user is protected from air flow noise while resting within the tent.
In a fifth embodiment of the present invention, based on the second embodiment of the above-mentioned vehicle-mounted air supply system control method, step S30 includes:
step S331, if the external opening signal is a natural wind mode signal;
and S332, controlling the vehicle-mounted air conditioner to exit the refrigeration mode and the heating mode.
In this embodiment, the natural wind mode refers to that the temperature of the air flow sent by the blower to the outside of the vehicle tends to the ambient temperature, so as to achieve a simple blowing function. It can be understood that on the basis of controlling the vehicle-mounted air conditioner to exit the refrigerating and heating modes, the blower of the vehicle-mounted air conditioner can be synchronously turned off, the blower of the vehicle-mounted air conditioner can be kept turned on, and if the blower is kept turned on, the negative pressure resistance of the air inlet side of the blower is reduced. It should be noted that, when the blower is made to send out natural wind to the outside of the vehicle, the air volume of the blower is adjustable, that is, the natural wind mode and the air volume of the blower can be set independently.
Step S333, opening all window openings.
It will be appreciated that the amount of air provided by the blower depends not only on the rotational speed of the blower, but also on the negative pressure resistance of the blower on the intake side. If all the window openings are opened, a great amount of continuously outside air can be obtained in the passenger cabin, so that the negative pressure resistance of the air inlet side (namely) of the air blower is reduced, and the air quantity of the air blower can be improved. Of course, in other embodiments, all window openings may not be opened, and only the window opening where the blower is located may be opened.
In a sixth embodiment of the present invention, based on the second embodiment of the present invention, step S30 includes:
Step S341, if the external opening signal is the most forced cold mode signal;
step S341, controlling the refrigerating power of the refrigerating module of the vehicle-mounted air conditioner to be maximum, the air quantity of the blower of the vehicle-mounted air conditioner to be maximum and the air quantity of the blower to be maximum.
In this embodiment, the most forced cooling mode controls the air volume and the cooling mode simultaneously, that is, controls the cooling power of the cooling module of the vehicle-mounted air conditioner to the maximum, the air volume of the blower of the vehicle-mounted air conditioner to the maximum, and the air volume of the blower to the maximum, so as to optimize the cooling effect when the blower sends air outwards. Of course, the most forced heat mode signal may be set to control the heating power of the heating module of the vehicle-mounted air conditioner to the maximum, the air volume of the blower of the vehicle-mounted air conditioner to the maximum, and the air volume of the blower to the maximum.
In a seventh embodiment of the present invention, based on the first embodiment of the above-mentioned vehicle-mounted air supply system control method, after step S30, the vehicle-mounted air supply system control method further includes:
step S41, detecting the residual quantity of a power battery of the vehicle;
And S42, if the residual electric quantity is smaller than or equal to the low electric quantity threshold value, closing the vehicle-mounted air supply system.
In this embodiment, by detecting the remaining power of the power battery and stopping the air supply function outside the vehicle in time (i.e. closing the vehicle-mounted air supply system), the problem that the user cannot drive the vehicle to return due to serious shortage of the power battery is avoided. For example, when a user takes a rest in a camp tent and forgets to turn off the off-vehicle air supply function before sleeping, serious shortage of the power battery may be caused if the off-vehicle air supply function is turned on for one night. Therefore, in this embodiment, by setting a low power threshold to monitor the power battery and timely shut down the vehicle-mounted air supply system, the above technical problems can be avoided. Particularly, when the vehicle-mounted air supply system controls the vehicle-mounted air conditioner to enter a cooling mode or a heating mode, the power consumption and the power consumption rate are high, and the power shortage of the vehicle may be caused by a little attention of a user.
Specifically, the low power threshold may be a default value preset when the vehicle leaves the factory, or may be a value that is changed by the user according to the actual requirement, for example, the low power threshold may be set to be between 20% and 30%, that is, when the remaining power of the power battery is lower than 20% (or 30%), the vehicle-mounted air supply system is controlled to leave the air supply mode outside the vehicle. Further optionally, all the electric devices on the whole vehicle are deactivated, so that the vehicle enters a deep energy-saving mode, and the electric energy loss rate of the power battery is further reduced.
In an eighth embodiment of the present invention, based on the first embodiment of the above-mentioned vehicle-mounted air supply system control method, step S20 includes:
step S21, if the external opening signal is a wind swinging mode signal;
And S22, controlling the blower to enter a wind swinging mode.
In this embodiment, the wind swinging mode refers to controlling the wind direction of the blower to swing left and right and/or up and down regularly, so that the air flow sent by the blower can cover a larger space range. Particularly, when a plurality of users gather on a certain field outside the vehicle, for example, a plurality of users sit side by side and do not far away from the vehicle for fishing, the air blower can enable the air flow to take care of more users after entering the air swinging mode, so that the use flexibility and convenience of the vehicle-mounted air supply system are improved.
In a ninth embodiment of the vehicle-mounted air supply system control method according to the present invention, for example, based on the eighth embodiment of the vehicle-mounted air supply system control method and the embodiment in which the blower is provided with two first nozzle segments and two fans with independently adjustable rotational speeds, the step S22 includes:
Step S221, generating a periodic control signal;
Step S222, respectively adjusting the rotating speeds of two fans of the air feeder according to the periodical control signals.
Specifically, in the embodiment in which the coanda effect degree formed on the two first tuyere sections is the same or different by adjusting the rotation speeds of the two motors, the processor of the vehicle-mounted air supply system may generate periodic control signals to control the two motors respectively, for example, please refer to the periodic control signals in fig. 4, in which the rotation speeds of the one fan 14 and the other fan 14 are all periodically changed between 50% and 100%, and the periodic phase difference between the one fan 14 and the other fan 14 is pi. Therefore, the blower 10 can have an automatic regular air-swinging function, so that the convenience in use of the blower 10 is further improved, and the user experience is improved. Of course, in other embodiments, the periodic control signal may be in other forms.
Of course, in embodiments in which the movable damper is adjusted to achieve the same or different degree of coanda effect formed on the two first tuyere sections, it is also possible to adjust the opening position of the movable damper in accordance with the periodic control signal.
In a tenth embodiment of the present invention, based on the first embodiment of the above-mentioned vehicle-mounted air supply system control method, after step S10, the vehicle-mounted air supply system control method further includes:
step S51, detecting the running speed of the vehicle;
And step S52, if the running speed is zero, starting the air feeder.
In this embodiment, whether the external air supply start signal is triggered by mistake is determined by detecting the running speed of the vehicle to determine whether the vehicle is in a parking state, and whether the vehicle-mounted air supply system enters an external air supply mode is determined according to the determination. It can be understood that, in general, only after the vehicle is parked in an outdoor place, the user needs to use the air supply function outside the vehicle, so if the vehicle is still running and the external opening signal is received, the external opening signal can be basically determined to be caused by false triggering, for example, when the user operates the vehicle-mounted central control screen or operates the vehicle control APP on the mobile phone, the starting instruction of the air supply function outside the vehicle is triggered by false triggering. Therefore, if the traveling speed is not zero, the vehicle-mounted air supply system does not enter the outside air supply mode. Therefore, the intelligent vehicle-mounted air supply system can be improved, and the user experience is improved. Of course, in other embodiments, the vehicle-mounted air supply system may enter the external air supply mode upon receiving the external air supply start signal, regardless of whether the running speed of the vehicle is zero.
In an eleventh embodiment of the present invention, based on the first embodiment of the above-mentioned vehicle-mounted air supply system control method, after step S20, the vehicle-mounted air supply system control method further includes:
step S60, receiving an external closing signal.
Specifically, in the embodiment of the present invention, the source of the external closing signal has various modes, for example, a user may operate a function key on the blower, operate a vehicle-mounted central control screen, or input a voice command in the passenger cabin, or the user may send a remote command to the vehicle by using an APP or a applet on an intelligent mobile terminal such as a mobile phone, a tablet computer, etc., so as to close the external air supply function of the vehicle-mounted air supply system, and generate the external closing signal. Of course, the user may also set the time of the reservation closure to shut down the off-vehicle air supply function at regular time. It should be noted that, in the seventh embodiment of the present invention, the power battery remaining capacity of the vehicle is detected to generate the power-off signal, that is, the power-off signal is generated if the remaining capacity is less than or equal to the low power threshold.
In addition, in the embodiment where the sensor is provided at the window opening where the blower is located, the sensor can generate the outward closing signal when the window glass at the window opening is raised to a preset position (for example, an upper limit position). Specifically, the sensor may be a distance sensor, a proximity switch, a tact switch, or the like. It will be appreciated that if the window opening to which the blower is attached is closed, this represents an off-board blower function that the user may wish to turn off the blower.
And S70, closing the vehicle-mounted air supply system and closing all window openings.
In this embodiment, after the external closing signal is received, the vehicle-mounted air supply and all the window openings are closed, so that the passenger cabin can be restored to the safe closed state in one step, and the operation times of the user for giving instructions can be saved. Of course, in other embodiments, it is also possible to simply turn off the vehicle air supply system, and the window opening remains open to be determined by the user whether to be closed. Of course, in other embodiments, it is also possible to obtain the vehicle state of the vehicle-mounted air supply system before entering the external air supply mode (for example, the previous second or the previous three seconds), including the working condition parameters of the vehicle-mounted air conditioner, the window opening condition, and the like, and then, after receiving the external air supply closing signal, restore the vehicle to the state of the vehicle-mounted air supply system before entering the external air supply mode.
The invention also provides a storage medium, wherein the storage medium stores a vehicle-mounted air supply system control program, and when the vehicle-mounted air supply system control program is executed by a processor, the steps of the vehicle-mounted air supply system control method can be realized.
