[0037] The present invention provides a vehicle air supply system and a vehicle having the vehicle air supply system. The vehicle air supply system is used for a vehicle, which includes a vehicle body, and the vehicle air supply system is disposed on the vehicle body. Please refer to Figure 7 , Figure 7 FIG. is a schematic structural diagram of a vehicle air supply system for a hardware operating environment according to an embodiment of the present invention. The vehicle air supply system may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0038] Those skilled in the art can understand that Figure 7 the structure shown in does not constitute a limitation on the vehicle air supply system, and it may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0039] As Figure 7 shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a vehicle air supply system control program. In the Figure 7 vehicle air supply system shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with users; the processor 1001 and the memory 1005 in the vehicle air supply system of the present invention may be disposed in the vehicle air supply system. The vehicle air supply system calls the vehicle air supply system control program stored in the memory 1005 through the processor 1001 and executes the control method of the vehicle air supply system provided by the embodiment of the present invention.

[0040] In an embodiment of the present invention, the vehicle air supply system includes a vehicle air conditioner and a blower. The vehicle air conditioner includes an air conditioner housing, a blower, a refrigeration module, and a heating module, all of which are provided in the air conditioner housing. Since the related structures and principles of the vehicle air conditioner belong to mature prior art, they will not be elaborated herein.

[0041] Please refer to Figure 5 and 6 , in an embodiment of the present invention, the vehicle body is provided with an occupant compartment and a window opening communicating with the occupant compartment. The blower is provided at the window opening and can supply air to the outside of the vehicle. It should be noted that the window opening 21 refers to the window on the vehicle body that can be opened movably. Taking a pickup truck model as an example, the window opening 21 includes, but is not limited to, the windows of the front doors, the windows of the rear doors, the rear window at the front end of the rear cargo bed, and the sunroof on the roof, etc. Please refer to Figures 1 to 3 , specifically and optionally, the blower includes:

[0042] A housing 11, provided with an air duct 11, an air inlet 12 and an air outlet 13 both communicating with the air duct 11. The air outlet 13 is provided with a slit-shaped air nozzle 131, and when the air flow blows out through the air nozzle 131, the Coanda effect can be formed; and

[0043] A blower 14, including a driving member and a wind wheel drivingly connected to the driving member, and at least part of the wind wheel is provided in the air duct 11.

[0044] In this way, the air volume multiplication effect of the Coanda effect can be used to increase the air volume of the blower, and the air exchange rate between the inside and outside of the occupant compartment can also be increased. Secondly, by installing the bladeless blower at the window opening, the negative impact of the blower on the view at the window opening can be reduced or even avoided, and the blower will not significantly affect the original shape of the vehicle, which is beneficial to improving the neatness and beauty of the vehicle. Of course, in other embodiments, the blower can also be configured as an ordinary fan structure with blades, or an ordinary blower structure.

[0045] In order to enrich the functions of the blower, please refer to Figures 1 to 3 , in an embodiment, the blower further includes a main control board provided on the housing 11. The air nozzle 131 includes two opposite first air nozzle segments 131a, and a blowing cavity 132 is formed between the two first air nozzle segments 131a at intervals; there are at least two blowers 14, and the at least two blowers 14 are respectively communicated with the two first air nozzle segments 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 segments 131a are the same or different.

[0046] Thus, by separately adjusting the air output of the two blowers 14 to be the same or different, the Coanda effect degrees formed on the two first air nozzle segments 131a can be the same or different, so as to change the direction of the air flow flowing through the air supply chamber 132. Specifically, assuming that the air outputs of the two blowers 14 are the same initially, the Coanda effects (including the air flow outward expansion trend and the air volume multiplication effect) on the two first air nozzle segments 131a are the same. At this time, the air flow blows outward along the axis of the air supply chamber 132 without deviation; when the air output of one blower 14 decreases while the other blower 14 remains unchanged, the Coanda effect on the first air nozzle segment 131a corresponding to one blower 14 will weaken accordingly, while the Coanda effect on the first air nozzle segment 131a corresponding to the other blower 14 remains unchanged, then the air supply direction of the air flow in the air supply chamber 132 will shift towards the side close to one blower 14, that is, towards the side close to the blower 14 with the decreased air output, so as to realize the function of automatically adjusting the air supply direction (i.e., wind direction adjustment) of the air blower 10 and improve the usability of the air blower 10. It should be noted that the air flow blowing outward means that the air flow is sent from the air inlet side of the air supply chamber 132 towards the air outlet side of the air supply chamber 132.

[0047] Optionally, in the embodiment of the present invention, the two first air nozzle segments 131a are respectively arranged on the left and right sides of the air blower 10, then the air flow blown out from the air supply chamber 132 can be made to swing left and right, that is, the left and right adjustment of the wind direction of the air blower 10 is realized. Of course, in some embodiments, the two first air nozzle segments 131a can also be respectively arranged on the upper and lower sides of the air blower 10 to realize the up and down adjustment of the wind direction of the air blower 10. In other embodiments, it can also be that 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, and at least four blowers 14 are correspondingly provided. The at least four blowers 14 are respectively connected to the two first air nozzle segments 131a and the two second air nozzle segments 131b. Thus, the up and down wind direction adjustment, the left and right wind direction adjustment and more complex and changeable wind direction adjustment of the air blower 10 can be realized.

[0048] Specifically, there are various ways to realize the adjustment of the air output of the blower 14. For example, in one embodiment, the main control board adjusts the rotation speed of the blower 14 to realize the adjustment of the air output, 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. This control logic is simple and easy to implement. That is, the air supply direction of the air flow in the air supply chamber 132 is changed by the rotation speed difference of the two blowers 14 to realize the wind direction adjustment of the air blower 10. Of course, in some embodiments, it can also be that the rotation speed of the blower 14 remains unchanged, and a movable air door electrically connected to the main control board is provided on the air outlet side of the blower 14, and the main control board adjusts the opening degree of the movable air door to realize the adjustment of the air output. In other embodiments, it can also be that the air output is adjusted by simultaneously adjusting the rotation speed of the blower 14 and the opening degree of the movable air door.

[0049] It can be understood that when the air output of the blower 14 is determined by the opening degree of the movable air door, only one blower 14 can be provided, and the air output flowing to the two first air nozzle sections 131a can be distributed by the movable air door. For example, in another embodiment, the air duct 11 includes a first branch and a second branch both communicating with the air outlet side of the blower 14, the first branch and the second branch respectively communicating with the two first air nozzle sections 131a, and the movable air door 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 blower 14 is equally or unequally distributed to the first branch and the second branch under the movement of the movable air door, so that the Coanda effects formed by the two first air nozzle sections 131a are the same or different. Of course, in other embodiments, two movable air doors can also be provided and are respectively rotatably arranged in the first branch and the second branch, and the two movable air doors can independently adjust the flow cross-sectional areas of the first branch and the second branch.

[0050] It is worth mentioning that the main control board may not be provided on the air blower, and the speed adjustment of the blower or the opening degree adjustment of the movable air door can be completed by the in-vehicle central control host or the control chip of the in-vehicle air conditioner, that is, the control function of the in-vehicle air supply system is integrated on the in-vehicle central control host or the in-vehicle air conditioner, thereby simplifying the structure of the air blower. Specifically, the air blower and the in-vehicle central control host (or the in-vehicle air conditioner) can be connected by either wired communication or wireless communication, and the wireless communication connection includes but is not limited to infrared communication, Bluetooth communication, Wi-Fi (wireless fidelity) communication, and 4G / 5G mobile communication, etc. It is worth mentioning that the control method of the blower is not limited to using PWM control, and lin, CAN, or voltage control, etc. can also be used.

[0051] Of course, the air direction adjustment of the air blower can also be realized through a mechanical rotation structure, for example, referring to the mechanical rotation structure for realizing the shaking head function on a common fan with fan blades. It can be understood that the technical solution of the present invention can be realized through simple air volume adjustment, and compared with the above-mentioned solution using a mechanical rotation structure, the structure is simpler and the operation is more stable and reliable.

[0052] To improve the strength and stability of the air flow in the air supply chamber 132, please refer to Figures 1 to 3, in one embodiment, the air outlet 13 is configured as an annular structure and encloses an air supply chamber 132. The air nozzle 131 further includes two opposite second air nozzle segments 131b. When the air flow blows out through the second air nozzle segments 131b, the Coanda effect can be formed. The second air nozzle segments 131b are communicated between the two first air nozzle segments 131a. In this way, the four sides of the air supply chamber 132 can be affected by the Coanda effect, and the air volume multiplication effect of the air flow formed therein is stronger, and the air flow is more condensed and the air supply direction is more stable. Moreover, the annular structure can improve the structural strength of the air outlet 13, which is beneficial to improving the service life of the air blower 10. Of course, in some embodiments, it may also be that the air outlet 13 is configured as an annular structure, but the second air nozzle segments 131b are not provided, that is, the two first air nozzle segments 131a are not communicated but only fixed together by a connecting bracket. In other embodiments, it may also be that only one second air nozzle segment 131b is provided and communicated between the two first air nozzle segments 131a, that is, the air outlet 13 is in a U-shaped structure.

[0053] Please refer to Figure 3 , in one embodiment, on the side of the air outlet 13 facing the air supply chamber 132, there are a first air guiding wall 13a and a second air guiding wall 13b. The first air guiding wall 13a and the second air guiding wall 13b are arranged in sequence along the air supply direction of the air supply chamber 132 and are spaced apart to form an air nozzle 131. In the air supply direction of the air supply chamber 132, the second air guiding wall 13b first extends obliquely towards the direction close to the axis of the air supply chamber 132 (the center of the air supply chamber 132), and then extends obliquely away from the axis of the air supply chamber 132. In this way, the air in the air duct 11 can have a tendency to first approach the axis of the air supply chamber 132 and then move away from the axis of the air supply chamber 132 when flowing out through the air nozzle 131, that is, the wall attachment effect of the air flow on the second air guiding wall 13b is improved, and further the air volume multiplication effect of the whole air flow in the air supply chamber 132 is improved. Of course, in other embodiments, it may also be that the first air guiding wall 13a and the second air guiding wall 13b are arranged in sequence along the air supply direction of the air supply chamber 132 and are spaced apart to form an air nozzle 131. In the air supply direction of the air supply chamber 132, the first air guiding wall 13a first extends obliquely towards the direction close to the axis of the air supply chamber 132, and then extends obliquely away from the axis of the air supply chamber 132; the second air guiding wall 13b extends obliquely away from the axis of the air supply chamber 132.

[0054] Please refer to Figures 1 to 3, in one embodiment, two first air nozzle segments 131a are respectively arranged on opposite sides of the air outlet 13 in its length direction, and two blowers 14 are respectively arranged on opposite sides of the air outlet 13 in its length direction. Thus, through this symmetric distribution, the center of gravity of the blower 10 can be closer to or fall on its centroid, and the height of its center of gravity can be reduced, which is beneficial to the use stability of the blower 10. Of course, in some embodiments, it can also be that two first air nozzle segments 131a are respectively arranged on opposite sides of the air outlet 13 in its width direction, and two blowers 14 are respectively arranged on opposite sides of the air outlet 13 in its length direction. In other embodiments, it can also be that two blowers 14 are arranged on the same side of the air outlet 13.

[0055] In one embodiment, the air duct 11 includes a columnar pipe section 11a, the impeller is configured as a centrifugal impeller and is arranged in the columnar pipe section 11a, and the axis of the columnar pipe section 11a and the axis of the centrifugal impeller both extend along the length direction of the air outlet 13. That is, the blower 14 is configured as a centrifugal blower 14. Thus, the structure of the blower 10 can be made more compact, which is beneficial to miniaturization design. Optionally in this embodiment, the air inlet 12 is arranged on the outer peripheral surface of the columnar pipe section 11a and is configured as a grille hole structure. Thus, 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 more smoothly in the air duct 11, which is beneficial to reducing the frictional loss of the air flow. Secondly, the grille hole structure of the air inlet 12 can play a certain role in dust prevention, water splash prevention and preventing mosquitoes from entering by mistake. Of course, in some embodiments, the blower 14 can also be configured as an axial flow blower 14, a cross-flow blower 14 or a rotary blower 14. In other embodiments, the air inlet 12 can also be arranged on the end surface of the columnar pipe section 11a.

[0056] Please refer to Figure 6 , in order to facilitate the user to control the functions of the blower 10, in one embodiment, the blower 10 further includes a function button 15 arranged on the housing 11, and the function button 15 is electrically connected to the main control board. Specifically, the function button 15 can be a physical button or a touch panel; the function button 15 can include a power switch, air volume size adjustment, wind direction adjustment and automatic swing of the air outlet, etc. Of course, in other embodiments, it can also be that no function button 15 is arranged on the housing 11, but a wireless transmission module (such as an infrared receiver or a Bluetooth module) is arranged on the main control board, and a remote controller is configured to realize remote function control of the blower 10.

[0057] In one embodiment, the air blower 10 further includes a power interface disposed on the housing 11, and the power interface is electrically connected to the main control board. Specifically and optionally, the power interface may include a DC power interface and an AC power interface, such as a 12V power interface and a 220V power interface. In this way, it is convenient for the user to select a suitable power source to supply power to the air blower 10 according to the actual situation. Optionally in this embodiment, the air blower is electrically connected to the vehicle power supply, that is, the vehicle power supply supplies power to the air blower to support its operation. Of course, in some embodiments, the air 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 rechargeable batteries or dry batteries.

[0058] Please refer to Figure 5 , in one embodiment, the vehicle body 20 includes a rear cargo bed (such as the cargo bed of a pickup truck model), the opening of the rear cargo bed faces upward and is used for carrying goods, the window opening 21 includes a rear window, the rear window is disposed on the front end face of the rear cargo bed, and the air outlet 13 is configured as an annular structure and is disposed on the edge of the rear window. Specifically and optionally, the inner contour size of the annular air outlet 13 is adapted to the opening size of the rear window, such as being equal to or slightly larger than the opening size of the rear window. In this way, it neither affects the normal use function of the rear window nor affects the normal operation of the air blower 10. It should be noted that in this embodiment, the window glass on the rear window is configured to be removably movable or movable up and down; the air blower 10 is not limited to blowing air to the outside of the vehicle, and can also blow air to the inside of the vehicle (i.e., the passenger compartment), which can be specifically adjusted according to design requirements.

[0059] It can be understood that taking the pickup truck model as an example, the front end face of its rear cargo bed is usually adjacent to or abuts against the rear end plate of the passenger compartment. The rear cargo bed can not only be used for loading goods, but also for users to move on it. For example, the user parks the vehicle by the river and sits on the rear cargo bed for fishing. In this way, the air blower 10 disposed on the rear window can provide a blowing function for the user. Further optionally, when the vehicle-mounted air supply system is turned on to adjust the temperature in the passenger compartment, such as refrigerating the passenger compartment, other window openings 21 are closed and only the rear window is retained. The air blower 10 on the rear window can send out the cold air in the passenger compartment together outside the vehicle, so as to realize blowing and refrigerating outside the vehicle, thereby improving the convenience of using the air supply function outside the vehicle.

[0060] Of course, the air blower 10 can also be installed as a detachable accessory on any structure of the vehicle body 20. For example, please refer to Figure 5 and 6, in one embodiment, the blower 10 further includes a mounting member 16 fixed to the housing 11, and the mounting member 16 is detachably connected to the edge of the window opening 21. Specifically and optionally, the mounting member 16 includes at least two straps 16, and the at least two straps 16 are respectively arranged on opposite sides of the blower 10. In this way, the blower 10 can be installed by tying the straps 16 to the edge of the window opening 21, with simple operation and a simple structure. Of course, in some embodiments, it can also be that the mounting member 16 includes a magnet, and the magnet can be adsorbed on the sheet metal part at the edge of the window opening 21; or the mounting member 16 includes a clamping structure, and a clamping hole is provided at the edge of the window opening 21, and the clamping structure can be clamped in the clamping hole.

[0061] The present invention also provides a control method for an in-vehicle air supply system for an in-vehicle air supply system of a vehicle. Please refer to Figure 8 , in the first embodiment of the control method for the in-vehicle air supply system of the present invention, the control method for the in-vehicle air supply system includes step S10 and step S20.

[0062] Step S10: Receive a signal for external opening.

[0063] Specifically, in the embodiments of the present invention, the source of the signal for external opening has various ways. For example, it can be that the user operates the function button on the blower, operates the in-vehicle central control screen or inputs a voice command in the passenger compartment. It can also be that the user uses an APP or a small program on a smart mobile terminal such as a mobile phone or a tablet computer to send a remote command to the vehicle to activate the out-of-vehicle air supply function of the in-vehicle air supply system, and a signal for external opening will be generated. Of course, the user can also set a reservation opening time to start the out-of-vehicle air supply function regularly.

[0064] It is worth mentioning that, in one embodiment, a sensor is provided at the window opening where the blower is located. When the window glass at this window opening descends to a preset position, the sensor can generate a signal for external opening. Specifically, the sensor can be a distance sensor, a proximity switch or a touch switch, etc. It can be understood that if the window opening where the blower is located is opened, it means that the user may want to activate the out-of-vehicle air supply function of the blower; particularly, when the window opening where the blower is located is not usually opened, such as the rear window of a pickup truck model, then when this window opening is opened, it is very likely that the user has a need to activate the out-of-vehicle air supply function.

[0065] The signal for external opening generated by any of the above methods can be received by the processor of the in-vehicle air supply system, and the in-vehicle air supply system can make corresponding responses according to different signals for external opening. For specific situations, please refer to the following text.

[0066] Step S20: Turn on the blower.

[0067] Specifically, in the embodiments of the present invention, the blower can be turned on alone without turning on the vehicle air conditioner. At this time, after the window opening where the blower is located is opened, the air flow formed by the blower can be sent out of the vehicle through the window opening to achieve the most basic function of supplying air outside the vehicle. At this time, the vehicle air supply system enters the air supply mode outside the vehicle. Of course, the blower and the vehicle air conditioner can also be turned on simultaneously.

[0068] It should be noted that the window opening can be manually opened by the user. For example, the user operates the vehicle central control screen to electrically lower the window glass on the window opening. It can also be controlled by an external opening signal to open the window opening together. That is, optionally in this embodiment, after step S10, the vehicle air supply system control method further includes: opening the window opening where the blower is located. In this way, the blower and its corresponding window opening are controlled to be opened simultaneously, which can save the number of operations for the user to issue commands, thereby improving the convenience of using the vehicle air supply system.

[0069] In the technical solution of the present invention, by setting a blower at the window opening and sending an external opening signal to the vehicle air supply system to make it enter the air supply mode outside the vehicle (at least turn on the blower), it is possible to blow an air flow outside the vehicle, so that the vehicle has the function of supplying air outside the vehicle, and the users outside the vehicle can be more comfortable physically and mentally under the action of this air flow. Moreover, if the vehicle air conditioner is supplying cold air or warm air to the passenger compartment, the cold air or warm air in the passenger compartment can also be blown towards the users outside the vehicle under the drive of the air flow generated by the blower, thereby further enhancing the effect of the air supply function outside the vehicle. In this way, the use functions of the vehicle can be enriched and the user experience can be improved.

[0070] It is worth mentioning that, further optionally in this embodiment, the vehicle air supply system further includes a ventilation pipe, which can be installed on the blower or the window opening to direct the air flow blown out by the blower to an area farther away from the vehicle. In this way, the flexibility and convenience of using the vehicle air supply system can be further improved.

[0071] In the second embodiment of the vehicle air supply system control method of the present invention, based on the first embodiment of the vehicle air supply system control method described above, after the step of turning on the blower, the vehicle air supply system control method further includes:

[0072] Step S30: Turn on the vehicle air conditioner.

[0073] Specifically, in the embodiments of the present invention, turning on the vehicle air conditioner may be to only start the blower of the vehicle air conditioner without synchronously starting the refrigeration module or the heating module; or it may be to synchronously start the blower and the refrigeration module, or synchronously start the blower and the heating module. The specific turning-on mode of the vehicle air conditioner is determined according to different external opening signals or user-set parameters. For example, optionally in this embodiment, it is possible to set a one-key start for the vehicle air supply system to enter the default turning-on mode, that is, to control the air volume of the air supply fan to be 50%, the air volume of the blower of the vehicle air conditioner to be 50%, the vehicle air conditioner to be in the external circulation mode, and to open the window where the air supply fan is located. That is, in the default turning-on mode, the vehicle air conditioner does not enter the refrigeration mode or the heating mode, and the air supply fan simply uses the Coanda effect at the air nozzle to send the air in the passenger compartment out of the vehicle. It can be understood that if the temperature in the passenger compartment is lower than the outside air temperature at this time, for example, the passenger compartment has experienced a refrigeration process before the air supply fan is turned on, then the air flow sent out of the vehicle by the air supply fan has a certain refrigeration effect, but obviously this refrigeration effect will not last. Of course, in other embodiments, the functional parameters corresponding to the default turning-on mode can also be configured in other forms.

[0074] In the third embodiment of the control method for the vehicle air supply system of the present invention, based on the second embodiment of the above-mentioned control method for the vehicle air supply system, step S30 includes:

[0075] Step S311: If the external opening signal is a refrigeration mode signal or a heating mode signal.

[0076] Specifically, the air conditioner mode signal includes a refrigeration mode signal and a heating mode signal. If the above-mentioned default turning-on mode cannot meet the user's needs, the user can adjust the functional parameters through the user interface (including function buttons on the air supply fan, the vehicle central control screen, the vehicle central control buttons, and the mobile phone APP, etc.) or voice control commands, such as adjusting the air volume, temperature, and wind direction angle, etc. Optionally in this embodiment, "refrigeration mode" and "heating mode" options can be provided, or the user-set temperature can be compared with the outside air temperature, and the corresponding air conditioner mode signal can be generated according to the comparison result. For example, assuming the outside air temperature is 28°C, when the user sets the temperature at 16°C (lower than the outside air temperature), it is determined that the user needs a refrigeration function, and a refrigeration mode signal is generated to control the vehicle air conditioner to enter the refrigeration mode, so that the blower and the refrigeration module of the vehicle air conditioner are synchronously started. Among them, the outside air temperature can be directly obtained through the temperature sensor on the vehicle body, or the local temperature of the location where the vehicle is located can be obtained through the Internet of Things or the Internet.

[0077] Step S312: Open the window where the air supply fan is located and close the remaining window openings.

[0078] Specifically, closing all the other window openings and only retaining the window opening where the blower is located can effectively reduce the leakage rate of cold air or warm air in the passenger compartment, and enable more cold air or warm air to be sent out of the vehicle through the blower, thus achieving a good effect of cooling or heating the air outside the vehicle.

[0079] Step S313: Control the vehicle-mounted air conditioner to enter the cooling mode or the heating mode.

[0080] In this embodiment, by cooperating the blower with the vehicle-mounted air conditioner, the cold air or warm air generated by the vehicle-mounted air conditioner can be sent out of the vehicle to adjust the air in a local space outside the vehicle, thereby improving the comfort and convenience of outdoor activities. And using the vehicle-mounted air conditioner to replace an independent portable outdoor air conditioner can save the purchase cost and maintenance cost of the portable outdoor air conditioner, and the structure of the blower itself is simple and the production cost is low, so as to enable users to experience the air conditioning function outdoors at a lower cost. It is worth mentioning that, optionally in this embodiment, the vehicle-mounted air supply system further includes a ventilation pipe, and the ventilation pipe can be installed on the blower or the window opening to direct the airflow blown out by the blower to an area farther away from the vehicle. When the user drives to a camping, picnic or fishing site, the cold air prepared by the vehicle-mounted air conditioner flows through the passenger compartment, the blower and the ventilation pipe in sequence until the site where the user is located. In this way, the flexibility and convenience of using the vehicle-mounted air supply system can be further improved. Of course, the ventilation pipe can also be used to further introduce the airflow into the camping tent to adjust the temperature in the tent.

[0081] Optionally in this embodiment, after step S311, step S30 further includes:

[0082] Step S314: Control the vehicle-mounted air conditioner to enter the external circulation mode.

[0083] In this embodiment, the external circulation mode of the vehicle-mounted air conditioner means that the air inlet of the blower is connected to 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; the internal circulation mode of the vehicle-mounted air conditioner means that the air inlet of the blower is connected to the space inside the vehicle, that is, the air entering the blower is the air from the passenger compartment. By adjusting the vehicle-mounted air conditioner to the external circulation mode, the gas flowing through the blower and the blower is the air from outside the vehicle, that is, the fresh air outdoors, so as to improve the blowing effect outside the vehicle. And it can be understood that the air in the passenger compartment is not only unclear due to being in a closed state, but may also carry harmful substances volatilized by the vehicle interior parts. By adopting the external circulation mode, the risk of harm to users caused by harmful volatiles in the passenger compartment can be reduced. Of course, in other embodiments, the vehicle-mounted air conditioner can also be turned on in the internal circulation mode. Since the external circulation mode and the internal circulation mode of the vehicle-mounted air conditioner are both mature existing technologies, they will not be elaborated here.

[0084] In the fourth embodiment of the control method of the vehicle-mounted air supply system of the present invention, based on the second embodiment of the above-mentioned vehicle-mounted air supply system control method, step S30 includes:

[0085] Step S321: If the external supply opening signal is a strong mode signal.

[0086] In this embodiment, a variety of function mode shortcut options can be provided on the user interaction interface for the user to select, including but not limited to natural wind mode, strong mode, gentle mode, maximum cooling mode (i.e., Max AC), and swing mode, etc. Operating the exclusive shortcut keys of these function modes will generate corresponding different external supply opening signals. That is to say, the external supply opening signal includes a variety of function mode signals, such as the corresponding natural wind mode signal, strong mode signal, gentle mode signal, maximum cooling mode signal, and swing mode signal, etc. After the vehicle-mounted air supply system receives different function mode signals, it controls the vehicle-mounted air conditioner and the blower to execute corresponding function parameters.

[0087] Step S322: Adjust the air volume of the blower of the vehicle-mounted air conditioner and the blower to the maximum value.

[0088] Specifically, the gentle mode and the strong mode in this embodiment only control the single factor of air volume. For example, adjusting the air volume of the blower to the maximum and the air volume of the blower of the vehicle-mounted air conditioner to the maximum is the strong mode, and adjusting the air volume of the blower to moderate (such as 20% to 40% of the air volume) is the gentle mode, regardless of whether the vehicle-mounted air conditioner is in the cooling or heating mode. In particular, the function parameters of the gentle mode are suitable for the use of the blower in combination with the tent, so that the user can be protected from the disturbance of the air flow noise when resting in the tent.

[0089] In the fifth embodiment of the control method of the vehicle-mounted air supply system of the present invention, based on the second embodiment of the above-mentioned vehicle-mounted air supply system control method, step S30 includes:

[0090] Step S331: If the external supply opening signal is a natural wind mode signal;

[0091] Step S332: Control the vehicle-mounted air conditioner to exit the cooling mode and the heating mode.

[0092] In this embodiment, the natural wind mode means that the temperature of the air flow sent by the blower to the outside of the vehicle tends to the ambient temperature to achieve a simple blowing function. It can be understood that on the basis of controlling the vehicle-mounted air conditioner to exit the cooling and heating modes, the blower of the vehicle-mounted air conditioner can be turned off synchronously, or the blower of the vehicle-mounted air conditioner can be kept on. If the blower is kept on, it is beneficial to reduce the negative pressure resistance on the air inlet side of the blower. It is worth mentioning that when the blower sends 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.

[0093] Step S333: Open all window openings.

[0094] It can be understood that the air volume of the air blower depends not only on the rotational speed of the blower on the air blower and the rotational speed of the blower on the vehicle-mounted air conditioner, but also on the negative pressure resistance on the air inlet side of the air blower. If all window openings are opened, a continuous large amount of outdoor air can be obtained inside the passenger compartment, thereby reducing the negative pressure resistance on the air inlet side (i.e.,) of the air blower, and further improving the air volume of the air blower. Of course, in other embodiments, not all window openings need to be opened, and only the window opening where the air blower is located needs to be opened.

[0095] In the sixth embodiment of the control method of the vehicle-mounted air supply system of the present invention, based on the second embodiment of the above-mentioned control method of the vehicle-mounted air supply system, step S30 includes:

[0096] Step S341: If the external opening signal is the maximum cooling mode signal;

[0097] Step S341: Control 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 air blower to the maximum.

[0098] In this embodiment, the maximum cooling mode controls both the air volume and the cooling mode, 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 air blower to the maximum, so as to achieve the best cooling effect when the air blower blows out air. Of course, a maximum heating mode signal can also 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 air blower to the maximum.

[0099] In the seventh embodiment of the control method of the vehicle-mounted air supply system of the present invention, based on the first embodiment of the above-mentioned control method of the vehicle-mounted air supply system, after step S30, the control method of the vehicle-mounted air supply system further includes:

[0100] Step S41: Detect the remaining power of the vehicle's power battery;

[0101] Step S42: If the remaining power is less than or equal to the low power threshold, turn off the vehicle-mounted air supply system.

[0102] In this embodiment, by detecting the remaining power of the power battery and timely stopping the external air supply function (i.e., turning off the in-vehicle air supply system), it is possible to avoid the problem that the power of the power battery is severely insufficient, resulting in the user being unable to drive the vehicle back. For example, when the user is resting in the camp tent and forgets to turn off the external air supply function before going to bed, if the external air supply function is turned on all night, it may cause the power of the power battery to be severely insufficient. Therefore, in this embodiment, by setting a low power threshold to monitor the power battery and timely turn off the in-vehicle air supply system, the above technical problems can be avoided. In particular, when the in-vehicle air supply system controls the in-vehicle air conditioner to enter the cooling mode or heating mode, its power consumption and power consumption rate are relatively large, and if the user is not careful, it may cause the vehicle's power to be insufficient.

[0103] Specifically, the low power threshold can be the default value preset when the vehicle leaves the factory, or the value changed by the user according to actual needs. For example, the low power threshold can be set between 20% and 30%. That is, when the remaining power of the power battery is lower than 20% (or 30%), the in-vehicle air supply system will be controlled to exit the external air supply mode. Further optionally, all the electrical devices on the vehicle are deactivated to make the vehicle enter the deep energy-saving mode, so as to further reduce the power consumption rate of the power battery.

[0104] In the eighth embodiment of the control method of the in-vehicle air supply system of the present invention, based on the first embodiment of the above control method of the in-vehicle air supply system, step S20 includes:

[0105] Step S21: If the external air supply opening signal is a swing mode signal;

[0106] Step S22: Control the air blower to enter the swing mode.

[0107] In this embodiment, the swing mode refers to controlling the air direction of the air blower to swing left and right and / or up and down regularly, so that the air flow sent by the air blower can cover a larger space range. In particular, when multiple users gather on a certain site outside the vehicle, for example, when multiple users are sitting side by side not far outside the vehicle fishing, after the air blower enters the swing mode, the air flow can take care of more users, thereby improving the flexibility and convenience of using the in-vehicle air supply system.

[0108] There are various ways to implement the swing mode. For example, in the ninth embodiment of the control method of the in-vehicle air supply system of the present invention, based on the eighth embodiment of the above control method of the in-vehicle air supply system and the embodiment in which the air blower is provided with two first air nozzle segments and two fans with independently adjustable speeds, step S22 includes:

[0109] Step S221: Generate a periodic control signal;

[0110] Step S222: Adjust the speeds of the two fans of the air blower respectively according to the periodic control signal.

[0111] Specifically, in embodiments where the Coanda effect formed on the two first nozzle sections is made the same or different by adjusting the rotational speeds of the two motors, or in embodiments where the blower swings left and right or up and down, the processor of the vehicle-mounted air supply system can generate a periodic control signal to separately control the two motors. For example, refer to Figure 4 the periodic control signal in the figure. In the figure, the rotational speeds of one blower 14 and the other blower 14 both vary periodically between 50% and 100%, and the periodic phase difference between one blower 14 and the other blower 14 is π. In this way, the blower 10 can be made to have an automatic and regular swinging function, further enhancing the convenience of use of the blower 10 and improving the user experience. Of course, in other embodiments, the periodic control signal can also be in other forms.

[0112] Of course, in embodiments where the Coanda effect formed on the two first nozzle sections is made the same or different by adjusting the movable air damper, the opening position of the movable air damper can also be adjusted according to the periodic control signal.

[0113] In the tenth embodiment of the control method for the vehicle-mounted air supply system of the present invention, based on the first embodiment of the control method for the vehicle-mounted air supply system, after step S10, the control method for the vehicle-mounted air supply system further includes:

[0114] Step S51: Detect the driving speed of the vehicle;

[0115] Step S52: If the driving speed is zero, turn on the blower.

[0116] In this embodiment, by detecting the driving speed of the vehicle to determine whether the vehicle is in a parked state, it is confirmed whether the external supply opening signal is mis-triggered, and based on this, it is determined whether the vehicle-mounted air supply system enters the external air supply mode. It can be understood that generally, only after the vehicle is parked outdoors will the user have a need to use the external air supply function. Therefore, if the vehicle is still moving but receives the external supply opening signal, it can basically be judged that the external supply opening signal is mis-triggered. For example, when the user operates the vehicle-mounted central control screen or the vehicle control APP on the mobile phone, the start command of the external air supply function is mis-triggered. Therefore, if the driving speed is not zero, the vehicle-mounted air supply system will not enter the external air supply mode. In this way, the intelligence of the vehicle-mounted air supply system can be improved, thereby improving the user experience. Of course, in other embodiments, it can also be that regardless of whether the driving speed of the vehicle is zero, once the vehicle-mounted air supply system receives the external supply opening signal, it enters the external air supply mode.

[0117] In the eleventh embodiment of the control method for the vehicle-mounted air supply system of the present invention, based on the first embodiment of the control method for the vehicle-mounted air supply system, after step S20, the control method for the vehicle-mounted air supply system further includes:

[0118] Step S60: Receive an external shutdown signal.

[0119] Specifically, in the embodiments of the present invention, the source of the external shutdown signal has various ways. For example, it can be that the user operates the function button on the blower, operates the in-vehicle central control screen, or inputs a voice command in the passenger compartment. It can also be that the user uses an APP or a small program on a smart mobile terminal such as a mobile phone or a tablet computer to send a remote command to the vehicle to turn off the external air supply function of the in-vehicle air supply system, and an external shutdown signal will be generated in all cases. Of course, the user can also set a scheduled shutdown time to turn off the external air supply function at a fixed time. It is worth mentioning that in the seventh embodiment of the present invention, by detecting the remaining power of the vehicle's power battery, an external shutdown signal is also generated, that is, if the remaining power is less than or equal to the low power threshold, an external shutdown signal is generated.

[0120] In addition, in an embodiment where a sensor is provided at the window opening where the blower is located, when the window glass on the window opening rises to a preset position (such as the upper limit position), the sensor can generate an external shutdown signal. Specifically, the sensor can be a distance sensor, a proximity switch, or a touch switch, etc. It can be understood that if the window opening where the blower is located is closed, it means that the user may want to turn off the external air supply function of the blower.

[0121] Step S70: Turn off the in-vehicle air supply system and close all window openings.

[0122] In this embodiment, after receiving the external shutdown signal, both the in-vehicle air supply is turned off and all window openings are closed, which can directly restore the passenger compartment to a safe and enclosed state, thus saving the number of operations for the user to issue commands. Of course, in other embodiments, it can also be to only turn off the in-vehicle air supply system, and the window openings are kept open for the user to decide whether to close. Of course, in other embodiments, it can also be to obtain the vehicle state before the in-vehicle air supply system enters the external air supply mode (such as the previous second or the previous three seconds), including the operating parameters of the in-vehicle air conditioner, the window opening situation, etc., and then when receiving the external shutdown signal, the vehicle is restored to the state before the in-vehicle air supply system enters the external air supply mode.

[0123] The present invention also proposes a storage medium storing a control program for an in-vehicle air supply system. When the control program for the in-vehicle air supply system is executed by a processor, it can implement the steps of the aforementioned control method for the in-vehicle air supply system.
