DETAILED DESCRIPTION

[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] In the first aspect, the present application embodiment provides an air supply device, see Figure 1 , including a gas supply unit 1 and an air storage unit 3. Among them, the gas supply unit 1 can provide high-pressure gas, which is suitable for being connected to the air receiving unit in the vehicle, so that the gas supply unit 1 inflates the air receiving unit 2. Among them, the air receiving unit 2 includes a first air receiving unit 21 and a second air receiving unit 22, the first air receiving unit 21 includes an air suspension assembly, and the second air receiving unit 22 includes at least one of a seat airbag assembly 221, a tire assembly 222, an engine air supply assembly (not shown in the figure) and a pneumatic brake assembly (not shown in the figure). Through the air supply device provided in the embodiment of the present application, it is possible to supply air to the air suspension assembly through the gas supply unit 1, and at least one of the seat airbag assembly 221, the tire assembly 222, the engine air supply assembly and the pneumatic brake assembly can also be supplied with air, thereby improving the integration, saving space in the vehicle, and reducing costs.

[0059] Among them, the engine air supply components mainly include valve groups and valve transmission group parts, such as valves, valve guides, valve seats and valve springs. The pneumatic brake components mainly include front brake chambers, compound brake chambers, parking brakes and emergency brake valves.

[0060] In addition, the second air receiving unit 22 may also include a throttle valve and a fuel injector. The throttle valve is located at the engine air intake and is used to control the intake amount, thereby affecting the fuel injection amount. The fuel injector is responsible for injecting fuel into the engine intake manifold.

[0061] It can be understood that the air supply device provided in the embodiment of the present application can theoretically integrate all components in the vehicle that require air supply, realize the air supply for multiple components through a gas supply unit 1, form an air supply system for the entire vehicle, and improve the space utilization rate in the vehicle.

[0062] In some embodiments, see Figure 1 and Figure 2 The gas supply device also includes a gas storage unit 3, which is suitable for communicating with the gas supply unit 1 so that the gas supply unit 1 can inflate the gas storage unit 3. The gas storage unit 3 is also suitable for communicating with the gas receiving unit 2 so that the gas storage unit 3 can inflate the gas receiving unit 2, or the gas in the gas receiving unit 2 can be stored in the gas storage unit 3.

[0063] That is, the gas supply device provided in the embodiment of the present application can supply gas through the gas storage unit 3 in addition to directly supplying gas to the gas receiving unit 2 through the gas supply unit 1, so as to select a suitable inflation method according to the state of the vehicle, thereby improving the noise problem of the vehicle during inflation. In addition, when the gas pressure of the gas receiving unit 2 is too high and the gas is deflated, the gas can also be stored in the gas storage unit 3, reducing the energy loss caused by directly defusing the gas to the outside.

[0064] Compared with directly inflating through the gas supply unit 1, inflating through the gas storage unit 3 is more efficient and can complete inflation under harsh environmental conditions (such as high pressure and low temperature).

[0065] In some embodiments, see Figure 1 and Figure 2 A control valve is provided between the gas receiving unit 2 and the gas supply unit 1, and between the gas receiving unit 2 and the gas storage unit 3. The gas inlet end of the control valve is kept full of gas.

[0066] The control valve can control the connection between the gas receiving unit 2 and the gas supply unit 1 or the gas storage unit 3, thereby realizing the management of gas charging and discharging. By keeping the gas inlet end of the control valve in a state of rushing gas, the gas receiving unit can be quickly inflated after the control valve receives the opening signal, thereby improving the response efficiency.

[0067] See also Figure 1 and Figure 2 For example, the air suspension assembly includes a first air suspension 211, a second air suspension 212, a third air suspension 213 and a fourth air suspension 214, and is respectively provided with a tenth control valve 411, an eleventh control valve 412, a twelfth control valve 413 and a thirteenth control valve 414. The air inlet end of the control valve refers to the end away from the air suspension assembly. When the control valve is opened, since the air inlet end is in a state of being filled with gas, the gas can quickly enter the air suspension assembly, significantly shortening the response time.

[0068] The seat airbag assembly 221 and the tire assembly 222 are also configured in a similar manner and will not be described in detail herein.

[0069] In some embodiments, see Figure 1 The gas storage unit 3 includes a first gas storage tank 31. The gas supply unit 1 includes a gas outlet. The gas outlet is suitable for communicating with the interface of the first gas receiving unit 21 and the interface of the first gas storage tank 31; the interface of the first gas storage tank 31 is also suitable for communicating with the interface of the first gas receiving unit 21.

[0070] The gas outlet of the gas supply unit 1 is connected to the interface of the first gas receiving unit 21, and the first gas receiving unit 21 can be directly inflated through the gas supply unit 1. The gas outlet of the gas supply unit 1 is connected to the interface of the first gas storage tank 31, and the gas generated by the gas supply unit 1 can be stored in the first gas storage tank 31. The interface of the first gas storage tank 31 is connected to the interface of the first gas receiving unit 21. On the one hand, the first gas receiving unit 21 can be inflated through the first gas storage tank 31, and on the other hand, when the first gas receiving unit 21 is deflated, the gas can be stored in the first gas storage tank 31 for recycling.

[0071] In some embodiments, see Figure 1 , a first control valve 41 is provided between the air outlet and the interface of the first air receiving unit 21. By providing the first control valve 41 between the air outlet and the interface of the first air receiving unit 21, the on-off between the air outlet and the interface of the first air receiving unit 21 can be controlled. When it is necessary to inflate the first air receiving unit 21 through the gas supply unit 1, the first control valve 41 is opened. When the inflation is completed, or the gas supply unit 1 is not needed to inflate the first air receiving unit 21, the first control valve 41 is closed to avoid gas leakage in the first air receiving unit 21.

[0072] In some embodiments, see Figure 1 A second control valve 42 is provided between the gas outlet and the interface of the first gas storage tank 31. Similarly, by controlling the second control valve 42, the on-off between the gas outlet and the first gas storage tank 31 can be controlled.

[0073] In some embodiments, a third control valve 43 is provided between the interface of the first gas storage tank 31 and the interface of the first gas receiving unit 21. Similarly, by controlling the third control valve 43, the connection and disconnection between the first gas storage tank 31 and the first gas receiving unit 21 can be controlled.

[0074] It is understandable that the expressions "first", "second", "third" and the like in this application are used to distinguish the on-off control between different components, and can be different structures or the same structure. Figure 1 The third control valve 43 is not separately provided between the interface of the first gas storage tank 31 and the interface of the first gas receiving unit 21. When the first control valve 41 and the second control valve 42 are both opened, the interface of the first gas storage tank 31 and the interface of the first gas receiving unit 21 are connected.

[0075] In some embodiments, see Figure 1 A first dryer 51 is provided between the gas outlet and the interface of the first gas receiving unit 21. That is to say, the high-pressure gas output by the gas supply unit 1 is first dried by the first dryer 51 to remove moisture from the gas, reduce the corrosion of moisture to the first gas receiving unit 21, and improve the stability and service life of the first gas receiving unit 21.

[0076] In some embodiments, see Figure 1 A second dryer 52 is provided between the gas outlet and the interface of the first gas storage tank 31. The high-pressure gas output by the gas supply unit 1 is also dried by the second dryer 52 before entering the first gas storage tank 31. On the one hand, it prevents the moisture in the high-pressure gas from corroding the first gas storage tank 31. On the other hand, it ensures that the gas stored in the first gas storage tank 31 is in a dry state. When the first gas receiving unit 21 is inflated through the first gas storage tank 31, it can also reduce the corrosion of the moisture to the first gas receiving unit 21.

[0077] It is understandable that when the first dryer 51 and the second dryer 52 are provided at the same time, the first dryer 51 and the second dryer 52 can be different dryers or the same dryer, as long as the high-pressure gas output from the gas outlet can be dried before entering the first gas receiving unit 21 and the first gas storage tank 31. For example, refer to Figure 1 The first dryer 51 and the second dryer 52 are the same dryer.

[0078] In some embodiments, see Figure 1 The gas supply unit 1 further comprises an air inlet. A fourth control valve 44 is provided between the interface of the first gas storage tank 31 and the air inlet. The interface of the first gas storage tank 31 is adapted to be connected to the air inlet through the fourth control valve 44.

[0079] When the first gas receiving unit 21 needs to be inflated, it is necessary to ensure that the gas pressure of the gas filled is greater than the gas pressure in the first gas receiving unit 21. If the first gas storage tank 31 stores gas, but the gas pressure is lower than the gas pressure in the first gas receiving unit 21, the gas in the first gas storage tank 31 can be pressurized by the gas supply unit 1, and then the pressurized high-pressure gas is used to inflate the first gas receiving unit 21, which helps the first gas storage tank 31 to inflate the first gas receiving unit 21 under low pressure, and can make full use of the gas in the first gas storage tank 31. The fourth control valve 44 can control the connection and disconnection between the first gas storage tank 31 and the air inlet.

[0080] In some embodiments, see Figure 1 , a fifth control valve 45 is provided between the interface of the first air receiving unit 21 and the air inlet. The interface of the first air receiving unit 21 is suitable for being connected to the air inlet through the fifth control valve 45. When the first air receiving unit 21 needs to be exhausted and stored in the first air storage tank 31, if the air pressure in the first air receiving unit 21 is lower than the air pressure in the first air storage tank 31, the air first enters the gas supply unit 1 through the interface and the air inlet of the first air receiving unit 21 for pressurization, and then the pressurized gas is stored in the first air storage tank 31. The on-off between the first air receiving unit 21 and the air inlet can be controlled by the fifth control valve 45.

[0081] In some embodiments, see Figure 1 The interface of the first gas storage tank 31 is also suitable for communicating with an external interface. The first gas storage tank 31 can exhaust gas through the external interface.

[0082] In some embodiments, the interface of the first air receiving unit 21 is also suitable for communicating with an external interface. The first air receiving unit 21 can also exhaust air through the external interface.

[0083] In some embodiments, see Figure 1 A sixth control valve 46 is provided between the interface of the first gas storage tank 31 and the external interface. The sixth control valve 46 can control the on-off between the first gas storage tank 31 and the external interface, and the sixth control valve 46 is opened when exhaust is required, and closed when exhaust is not required.

[0084] In some embodiments, a seventh control valve 47 is provided between the interface of the first air receiving unit 21 and the external interface. The seventh control valve 47 can control the on-off between the first air receiving unit 21 and the external interface, and the seventh control valve 47 is opened when exhaust is required, and closed when exhaust is not required.

[0085] See also Figure 1 , the sixth control valve 46 and the seventh control valve 47 can be the same control valve.

[0086] In some embodiments, see Figure 1 The first dryer 51 is located on the connecting pipeline between the interface of the first gas storage tank 31 and the external interface, and / or the first dryer 51 is located on the connecting pipeline between the interface of the first gas receiving unit 21 and the external interface.

[0087] Since the gas in the first gas storage tank 31 and the first gas receiving unit 21 is dried gas, when the first gas storage tank 31 and / or the first gas receiving unit 21 exhausts gas to the outside, the exhausted dry gas can first pass through the first dryer 51, thereby taking out the moisture in the first dryer 51 and regenerating the first dryer 51.

[0088] In some embodiments, see Figure 1 The second dryer 52 is located on the connecting pipeline between the interface of the first gas storage tank 31 and the external interface, and / or the second dryer 52 is located on the connecting pipeline between the interface of the first gas receiving unit 21 and the external interface.

[0089] Similarly, the second dryer 52 will also be regenerated during the exhaust process. The specific principle and process are similar to those of the first dryer 51 and will not be repeated here.

[0090] In some embodiments, see Figure 1 The air receiving unit 2 further includes a second air receiving unit 22, and the air storage unit 3 further includes a second air storage tank 32. The air outlet is also suitable for communicating with the interface of the second air receiving unit 22 and the interface of the second air storage tank 32. The interface of the second air storage tank 32 is also suitable for communicating with the interface of the second air receiving unit 22.

[0091] In some embodiments, an eighth control valve 48 is provided between the air outlet and the interface of the second air receiving unit 22 .

[0092] The high-pressure gas outputted by the gas supply unit 1 is communicated with the interface of the second gas receiving unit 22 through the gas outlet. The eighth control valve 48 can control the connection and disconnection between the gas outlet and the second gas receiving unit 22.

[0093] In some embodiments, see Figure 1 A ninth control valve 49 is provided between the interface of the second gas storage tank 32 and the interface of the second gas receiving unit 22 .

[0094] The interface of the second gas storage tank 32 is connected to the interface of the second gas receiving unit 22, and the second gas receiving unit 22 can be inflated through the second gas storage tank 32, and when the second gas receiving unit 22 is exhausted, the gas can also be stored in the second gas storage tank 32. The ninth control valve 49 can control the connection and disconnection between the second gas storage tank 32 and the second gas receiving unit 22.

[0095] In some embodiments, see Figure 1A first pressure limiting valve 61 is provided between the air outlet and the interface of the second air receiving unit 22 .

[0096] By setting a first pressure-limiting valve 61 on the connecting pipeline between the air outlet and the interface of the second air receiving unit 22, when the gas supply unit 1 outputs high-pressure gas greater than the pressure limiting range of the first pressure-limiting valve 61, the first pressure-limiting valve 61 opens, and the high-pressure gas enters the second air receiving unit 22, and then the second air receiving unit 22 is inflated. The greater the pressure of the high-pressure gas, the greater the opening of the first pressure-limiting valve 61, which can increase the inflation rate and ensure inflation stability.

[0097] In some embodiments, see Figure 1 A second pressure limiting valve 62 is provided between the interface of the second gas storage tank 32 and the interface of the second gas receiving unit 22. The second pressure limiting valve 62 has substantially the same function as the first pressure limiting valve 61, and will not be described in detail herein.

[0098] It can be understood that, when the first pressure-limiting valve 61 and the second pressure-limiting valve 62 exist at the same time, the first pressure-limiting valve 61 and the second pressure-limiting valve 62 can be different pressure-limiting valves or the same pressure-limiting valve.

[0099] In some embodiments, see Figure 1 The eighth control valve 48 and the ninth control valve 49 are also disposed between the gas outlet and the interface of the second gas storage tank 32. The eighth control valve 48 and the ninth control valve 49 can control the on-off of the gas outlet and the second gas storage tank 32 to adjust the charging mode.

[0100] In some embodiments, the tire assembly 222 includes a plurality of tires, and a tire pressure sensor 20 is disposed on each tire.

[0101] The tire pressure sensor 20 can monitor the air pressure of each tire and manage the inflation and deflation of the tire as needed.

[0102] In some embodiments, the tire pressure sensor 20 is electrically connected to the vehicle controller, and the controller is electrically connected to the control valve. The tire pressure data of the tire is obtained by the tire pressure sensor 20, and the controller can open or close the corresponding control valve according to the tire pressure data, thereby managing the inflation and deflation of the tire pressure, effectively ensuring the tire life and driving safety.

[0103] In some embodiments, see Figure 2 The gas supply unit 1 includes a compressor 11. The compressor 11 can compress the gas to form high-pressure gas, and then use the high-pressure gas to inflate the gas receiving unit 2, thereby ensuring the inflation effect and inflation efficiency.

[0104] Exemplarily, the compressor 11 may be a suspended air compressor (five-element pump).

[0105] In some embodiments, see Figure 2 The gas supply unit 1 further includes a power limiting valve 12. A first end of the power limiting valve 12 is communicated with the air inlet, and a second end of the power limiting valve 12 is communicated with the air outlet. By setting the power limiting valve 12, when the pressure build-up of the compressor 11 exceeds a preset value, the power limiting valve 12 is opened to achieve pressure relief, thereby protecting the compressor 11.

[0106] For example, the preset value of the power limiting valve 12 may be set to 20 bar. It is understood that a suitable preset value may be set according to the model of the compressor 11 used.

[0107] In some embodiments, see Figure 3-Figure 5 The gas supply unit 1 and the valve body assembly are integrated to form an integrated gas supply module 100 . The valve body assembly includes at least one of a first control valve 41 , a second control valve 42 and a third control valve 43 .

[0108] That is to say, in the embodiment of the present application, the gas supply unit 1 and the valve body assembly are integrated into an integrated gas supply module 100, thereby improving the integration of the inflation device.

[0109] See also Figure 3 and Figure 5 The integrated gas supply module 100 integrates the gas supply unit 1 and the first control valve 41, the second control valve 42, the third control valve 43, the fourth control valve 44, the fifth control valve 45, the sixth control valve 46, the seventh control valve 47, the eighth control valve 48, the tenth control valve 411, the eleventh control valve 412, the twelfth control valve 413 and the thirteenth control valve 414. Please refer to Figure 4 The integrated gas supply module 100 integrating the gas supply unit 1 and the valve body assembly has a high degree of integration and a small volume, which helps to reduce the volume of the gas supply device and improve the layout flexibility.

[0110] According to the second aspect of the present application, a vehicle inflation and deflation system is also provided, comprising an air supply device and an air receiving unit 2 as described above.
