Description

Technical Field

[0001] This utility model belongs to the field of automotive control technology, and in particular relates to a vehicle air management system and a vehicle. Background Technology

[0002] As people's living standards improve, their demands for automotive comfort are increasing, leading to a gradual increase in air-related mechanisms within vehicles, such as seat side support mechanisms, seat massage mechanisms, and camera cleaning mechanisms. If each air-related mechanism were equipped with a separate gas compression device, it would not only take up space, but the noise emitted by the gas compression devices during operation could also adversely affect the driver and passengers. Therefore, the design of the vehicle's air supply management system needs to comprehensively consider all air-related mechanisms in the vehicle to reduce the number of gas compression devices.

[0003] In some existing publicly available automotive air supply systems, the air suspension mechanism is used to supply air to other air-consuming components, eliminating the need for a separate gas compression device for each component. This saves space and reduces interior noise. For example, patent document CN221340508U discloses an air supply system and vehicle that supplies air to the seat side wing support mechanism via air suspension airbags, air suspension air tanks, or seat side wing air tanks. However, all three methods involve the air suspension system supplying air to the seat side wing support mechanism through a pressure relief valve, rather than directly supplying air to the seat via a compressor. The high-pressure air in the air suspension system needs to reach a maximum pressure of 12 bar, and the pressure in the air suspension air tank is even higher, reaching a maximum of 20 bar. The seat side wing support mechanism requires an air pressure less than 1 bar. Supplying air to the seat side wing support mechanism via the high-pressure air in the air suspension system would consume a large amount of high-pressure air through the pressure relief valve. Furthermore, most air-using mechanisms, except for the air suspension mechanism, do not have as high requirements for air dryness. If the high-pressure gas used by other air-using mechanisms also needs to be dried by the dryer provided for the air suspension mechanism, it will reduce the service life of the dryer. Another patent document, CN119872159A, discloses an integrated air supply unit for air suspension, which connects an external air supply valve in parallel with the four air spring valves of the air suspension mechanism. Although it can supply air to the outside through a compressor and the external air supply valve, when it performs the external air supply function, it closes the air spring valves corresponding to the four air springs and supplies air to the outside through the air suspension storage tank. The pressure of the external air supply is very high, and there is still a large pressure difference between the air pressure required by the air-using mechanism and the air pressure in the air suspension storage tank, resulting in the problem of high-pressure gas waste. Utility Model Content

[0004] In view of this, the present invention proposes a vehicle air management system, which at least solves the problem mentioned above that existing vehicle air management systems waste a large amount of high-pressure air due to the large pressure difference when supplying air to other air-consuming mechanisms through the high-pressure air of the air suspension system.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A vehicle air management system includes an air suspension mechanism, at least one other air-consuming mechanism, and an air supply mechanism. The air suspension mechanism is connected to a first air tank, which supplies and returns air to the air suspension mechanism, or the first air tank supplies air to the air suspension mechanism. The air supply mechanism includes a gas compression device, which is connected to the air suspension mechanism, the first air tank, and each of the other air-consuming mechanisms to directly supply air to the air suspension mechanism and the first air tank, and to directly supply air to the other air-consuming mechanisms or indirectly supply air to the other air-consuming mechanisms through the other air tanks.

[0007] In some embodiments, the other air-using mechanism is one of the following: a camera cleaning mechanism, a seat side wing support mechanism, an external inflation mechanism, and a seat massage mechanism.

[0008] In some embodiments, the other air-using mechanism is an external inflation mechanism, which is used to supply air to at least one of the tires, air mattresses, oxygen generators, pneumatic struts, and cooling mechanisms.

[0009] In some embodiments, a dryer is also connected between the gas compression device and the air suspension mechanism.

[0010] In some embodiments, the other gas-using mechanism in the vehicle air management system is a camera cleaning mechanism, and the outlet of the gas compression device is connected to the inlet of the first pressure limiting valve through a fifth switching valve, and the outlet of the first pressure limiting valve is connected to the inlet of the camera cleaning mechanism.

[0011] In some embodiments, the other gas-using mechanism in the vehicle air management system is an external inflation mechanism, and the outlet of the gas compression device is connected to the inlet of the external inflation mechanism through a sixth switching valve.

[0012] In some embodiments, the other gas-using mechanism in the vehicle air management system is a seat side wing support mechanism, the outlet of the gas compression device is connected to the inlet of the second air tank through a seventh switching valve, the outlet of the second air tank is connected to the inlet of the second pressure limiting valve through an eighth switching valve, and the outlet of the second pressure limiting valve is connected to the inlet of the seat side wing support mechanism.

[0013] In some embodiments, the outlet of the second gas tank is also connected to the inlet of the third pressure relief valve via a ninth switching valve, the outlet of the third pressure relief valve is connected to the inlet of the seat massage mechanism, and the outlet of the seat massage mechanism is also connected to the inlet of the gas compression device via a second one-way valve.

[0014] In some embodiments, the other gas-using mechanism in the vehicle air management system is a seat massage mechanism. The outlet of the gas compression device is connected to the inlet of a ninth switching valve and a third pressure limiting valve. The outlet of the third pressure limiting valve is connected to the inlet of the seat massage mechanism. The outlet of the seat massage mechanism is also connected to the inlet of the gas compression device through a second one-way valve.

[0015] This utility model also provides a vehicle, which includes the vehicle air management system described in any of the preceding claims.

[0016] Compared to existing technologies, the vehicle air management system provided by this utility model comprehensively considers the air demand of the entire vehicle during the overall vehicle design. The gas compression device in the air supply mechanism is connected to the air suspension mechanism, the first air tank, and various other air-consuming mechanisms. This is equivalent to directly supplying air to each air-consuming mechanism through the gas compression device. Compressed air can be output to each air-consuming mechanism according to its required compressed air pressure, instead of indirectly supplying air to other air-consuming mechanisms through the first air tank used to supply air to the air suspension mechanism and a pressure relief valve or pressure limiting valve. Because the pressure difference between the first air tank used for the air suspension mechanism and other air-consuming mechanisms is large, avoiding indirect air supply through the first air tank and pressure relief valve or pressure limiting valve prevents the waste of large amounts of high-pressure air, thus resulting in lower energy consumption for the vehicle air management system provided in this application. Therefore, the vehicle air management system provided in this application has the advantages of reasonable overall layout and high energy efficiency.

[0017] The vehicle provided by this utility model has the advantages of the aforementioned vehicle air management system, which will not be elaborated here. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

In actual working conditions, it is generally not the case that all gas-using mechanisms work at the same time. Except for the seat massage mechanism, the working state of other gas-using mechanisms is not continuous. When actually using this system, the control algorithm can also be used to prevent the simultaneous activation of various functions).

When actually using this system, the control algorithm can also be used to prevent the simultaneous activation of various functions). Figure 8 for Figure 2 A schematic diagram showing the first air storage tank supplying air to the air suspension mechanism.

[0031] This application provides a vehicle air management system including an air suspension mechanism, at least one other air-consuming mechanism, and an air supply mechanism. Generally, each other air-consuming mechanism has a different function; however, among multiple other air-consuming mechanisms, two with the same function can also be provided. The air suspension mechanism is connected to a first air tank 17, which supplies and returns air to the air suspension mechanism. Figure 5 The diagram shows the gas flow direction supplied by the first air tank 17 to the air suspension mechanism. Figure 6This illustrates the gas flow direction for the first air storage tank 17 to return air to the air suspension mechanism. Alternatively, the first air storage tank 17 can supply air to the air suspension mechanism. Figure 8 The diagram illustrates the gas flow direction when the first gas storage tank 17 supplies gas only to the air suspension mechanism. The gas supply mechanism includes a gas compression device 22, such as... Figure 4 and Figure 7 As shown, the gas compression device 22 is connected to the air suspension mechanism, the first air storage tank 17 and various other air-using mechanisms, respectively, to directly supply air to the air suspension mechanism and the first air storage tank 17, and to directly supply air to other air-using mechanisms or indirectly supply air to other air-using mechanisms through other air storage tanks.

[0032] Under normal circumstances, the first air tank 17, as an air tank that is only matched with the air suspension mechanism for air supply, will not supply or return air to other air-consuming mechanisms.

[0033] The vehicle air management system provided in this application comprehensively considers the air demand of the entire vehicle during the overall vehicle design. The gas compression device 22 in the air supply mechanism is connected to the air suspension mechanism, the first air tank 17, and various other air-consuming mechanisms. This is equivalent to directly supplying air to each air-consuming mechanism through the gas compression device 22. Compressed air can be output to each air-consuming mechanism according to its required compressed air pressure, instead of indirectly supplying air to other air-consuming mechanisms through the first air tank 17 (used for supplying air to the air suspension mechanism) and the pressure relief valve 21 or pressure limiting valve. Because the pressure difference between the first air tank 17 (used for air suspension mechanism) and other air-consuming mechanisms is large, the first air tank 17 can contain high-pressure gas to meet the air supply demand of the air suspension mechanism. Under normal circumstances, the first air tank 17 does not indirectly supply air to other air-consuming mechanisms through the pressure relief valve 21 or pressure limiting valve. Therefore, the waste of high-pressure gas in the first air tank 17 is effectively avoided, resulting in lower energy consumption for the vehicle air management system provided in this application embodiment.

[0034] Therefore, the vehicle air management system provided in this application has the advantages of reasonable overall layout and energy efficiency.

[0035] In some embodiments, other air-using mechanisms are one of the following: camera cleaning mechanism 28, seat side wing support mechanism 31, external inflation mechanism 29, and seat massage mechanism 33. That is, the vehicle air management system provided in this application embodiment can supply air to one or more of the following: camera cleaning mechanism 28, seat side wing support mechanism 31, external inflation mechanism 29, and seat massage mechanism 33, thus making the vehicle air management system provided in this application embodiment fully functional. Of course, in other embodiments, the air-using mechanism can also be other mechanisms that require high-pressure air.

[0036] When other air-consuming mechanisms are external inflation mechanisms 29, the external inflation mechanism 29 is used to supply air to at least one of the tires, air mattresses, oxygen generators, pneumatic struts, and cooling mechanisms. That is, the external inflation mechanism 29 can cooperate with the interfaces of the tires, air mattresses, oxygen generators, pneumatic struts, and cooling mechanisms, making the vehicle air management system provided in this application embodiment highly compatible.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, a dryer 24 is also connected between the gas compression device 22 and the air suspension mechanism. That is, a dryer 24 is first connected at the outlet of the gas compression device 22, and the outlet of the dryer 24 is then connected to the air suspension mechanism.

[0038] In a vehicle air management system provided in this application embodiment, a dryer 24 is also connected between the gas compression device 22 and the air suspension mechanism, so that the dryer 24 is only used to dry the gas entering the air suspension system. Since it does not indirectly supply gas to other gas-using mechanisms through the first air storage tank 17 and the pressure relief valve or pressure limiting valve used for the air suspension mechanism, other gas-using mechanisms no longer indirectly share the dryer 24 of the air suspension mechanism, which can increase the service life of the dryer 24 equipped for the air suspension mechanism and extend the regeneration cycle of the dryer 24.

[0039] like Figure 1 As shown, in some embodiments, the air supply method for the air suspension mechanism can be a closed system. A characteristic of a closed system is that when the air suspension mechanism descends, the high-pressure air inside is recovered into the first air storage tank 17, which has the advantage of not wasting high-pressure air. At this time, the inlet of the gas compression device 22 is connected to the air filter 18 through the first one-way valve 19. The air filter 18 is used to filter the air from the atmospheric air source 37. The inlet of the gas compression device 22 is also connected to the first air storage tank 17 through the fourth switching valve 4, allowing the air compressor to directly compress the high-pressure air in the first air storage tank 17 and deliver it to the air suspension mechanism, reducing the compression time and thus reducing the response time for delivering high-pressure air to the air suspension mechanism. The inlet of the gas compression device 22 is also connected to the air suspension mechanism through the first switching valve 2, so that the gas discharged from the air suspension mechanism can enter the gas compression device 22, be compressed, and then return to the first air storage tank 17, recovering the high-pressure air for recycling.

[0040] The outlet of the gas compression device 22 is connected to the exhaust mechanism 26 via the exhaust valve 25. This exhaust is used to vent air during the emergency descent of the air spring in the air suspension mechanism and also to vent air during the regeneration of the dryer 24. The outlet of the gas compression device 22 is also connected to the air suspension mechanism via the first switching valve 1 to directly supply air to the air suspension mechanism. The outlet of the gas compression device 22 is also connected to the first air storage tank 17 via the third switching valve 3 to replenish or return air to the first air storage tank 17 via the gas compression device 22. It can be understood that when air from the atmospheric air source 37 passes through the air filter 18 and the gas compression device 22 into the first air storage tank 17, it replenishes the first air storage tank 17. When high-pressure air from the air suspension mechanism passes through the gas compression device 22 into the first air storage tank 17, it returns air to the first air storage tank 17.

[0041] Based on the above embodiment, a dryer 24 is connected between the outlet of the gas compression device 22 and the first switching valve 1 and the third switching valve 3. Specifically, a dryer 24 is first connected to the outlet of the gas compression device 22, and the outlet of the dryer 24 is then connected to the air suspension mechanism via the first switching valve 1, and also to the first air storage tank 17 via the third switching valve 3. This allows for the drying of not only the high-pressure gas entering the air suspension mechanism from the air compressor outlet, but also the high-pressure gas entering the first air storage tank 17 from the air compressor outlet, thereby improving the service life of the air suspension mechanism.

[0042] Preferably, the outlet of the dryer 24 is connected to the inlet of the one-way throttle valve 23, and the outlet of the one-way throttle valve 23 is simultaneously connected to the manual exhaust valve 34, the first switching valve 1, and the third switching valve 3. The one-way throttle valve 23 is configured such that when the air suspension mechanism and the first air tank 17 are replenished, the gas flows forward through the one-way valve in the one-way throttle valve 23, and when the dryer 24 is regenerated, the gas flows backward through the throttle valve in the one-way throttle valve 23 at a certain rate. The manual exhaust valve 34 is provided for easy venting during maintenance.

[0043] Specifically, the air suspension mechanism includes four air springs 16 arranged in parallel. Each of the first switching valve 1 and the first switching valve 2 is connected to a first air spring valve 11, a second air spring valve 12, a third air spring valve 13, and a fourth air spring valve 14 corresponding to the four air springs 16. The four air springs 16 correspond to the four wheels of the vehicle, and the first air spring valve 11, the second air spring valve 12, the third air spring valve 13, and the fourth air spring valve 14 can control the inflation and deflation of each air spring 16. Each of the first air spring valve 11, the second air spring valve 12, the third air spring valve 13, the fourth air spring valve 14, the first switching valve 1, and the first switching valve 2 is connected to a pressure sensor 15 so that the pressure sensor 15 can detect the pressure in each air spring 16, the air supply pressure, and the pressure in the first air tank 17.

[0044] like Figure 2 As shown, in some embodiments, the air supply method for the air suspension mechanism can also be an open system. The characteristic of an open system is that when the air suspension mechanism descends, the high-pressure air inside is directly discharged to the atmosphere. Its advantages include a simpler air path layout and lower cost. In this case, the inlet of the gas compression device 22 is connected to the air filter 18 via a first one-way valve 19. The air filter 18 is used to filter the air from the atmospheric air source 37. The outlet of the gas compression device 22 is connected to the air suspension mechanism, and also to the exhaust mechanism 26 via an exhaust valve 25, and to the first air storage tank 17 via a tenth switching valve 10. Preferably, the outlet of the gas compression device 22 is provided with a third one-way valve 35 to prevent gas backflow.

[0045] In addition, regardless of whether the air supply method of the air suspension mechanism is a closed system or an open system, a pressure relief valve 21 is connected between the outlet of the gas compression device 22 and the atmospheric gas source 37 to prevent the gas pressure discharged from the outlet of the gas compression device 22 from being too high.

[0046] like Figures 1-3 As shown, in some embodiments, another gas-consuming mechanism in the vehicle air management system provided in this application is a camera cleaning mechanism 28. The outlet of the gas compression device 22 is connected to the inlet of the first pressure limiting valve 27 through the fifth switching valve 5, and the outlet of the first pressure limiting valve 27 is connected to the inlet of the camera cleaning mechanism 28. The gas compression device 22 can directly supply gas at a suitable pressure to the camera cleaning mechanism 28, and the first pressure limiting valve 27 can limit the pressure to below 5 bar to prevent excessively high air pressure from damaging the camera.

[0047] like Figures 1-3As shown, in some embodiments, another gas-using mechanism in the vehicle air management system provided in this application is an external inflation mechanism 29, and the outlet of the gas compression device 22 is connected to the inlet of the external inflation mechanism 29 through a sixth switching valve 6. The gas compression device 22 can also supply gas at a suitable pressure to the external inflation mechanism 29 according to the object being inflated.

[0048] like Figures 1-3 As shown, in some embodiments, another air-using mechanism in the vehicle air management system provided in this application is the seat side wing support mechanism 31. The outlet of the gas compression device 22 is connected to the inlet of the second air tank 36 through the seventh switching valve 7. The outlet of the second air tank 36 is connected to the inlet of the second pressure limiting valve 30 through the eighth switching valve 8. The outlet of the second pressure limiting valve 30 is connected to the inlet of the seat side wing support mechanism 31. The second pressure limiting valve 30 can limit the pressure to below 1 bar, preventing excessive air pressure from damaging the airbag of the seat side wing support mechanism 31. In addition, the second air tank 36 allows the high-pressure air in the airbag of the seat side wing support mechanism 31 to be filled more quickly, because the seat support usually requires a high response speed.

[0049] Based on the above embodiments, the outlet of the second air tank 36 is also connected to the inlet of the third pressure limiting valve 32 via the ninth switching valve 9. The outlet of the third pressure limiting valve 32 is connected to the inlet of the seat massage mechanism 33. The outlet of the seat massage mechanism 33 is also connected to the inlet of the gas compression device 22 via the second one-way valve 20. That is, the seat massage mechanism 33 can share a second air tank 36 with the seat side wing support mechanism 31. Since the pressure difference between the seat massage mechanism 33 and the seat side wing support mechanism 31 is small, sharing a second air tank 36 will not waste a lot of high-pressure air in the second air tank 36, and it can also save space.

[0050] like Figure 3 As shown, in some embodiments, another air-using mechanism in the vehicle air management system provided in this application is a seat massage mechanism 33. The gas compression device 22 is connected to the inlet of the ninth switching valve 9 and the third pressure limiting valve 32. The outlet of the third pressure limiting valve 32 is connected to the inlet of the seat massage mechanism 33. The outlet of the seat massage mechanism 33 is also connected to the inlet of the gas compression device 22 through the second one-way valve 20. The third pressure limiting valve 32 can limit the pressure to below 0.5 bar to prevent excessive air pressure from damaging the airbag of the seat massage mechanism 33. The outlet of the seat massage mechanism 33 is also connected to the inlet of the gas compression device 22 through the second one-way valve 20, which facilitates rapid inflation and deflation of the airbag in the seat massage mechanism 33, and allows the high-pressure air in the airbag of the seat massage mechanism 33 to be recycled.
