If the second air storage unit 12 supplies air to the first air receiving unit 50 at the same time, the fourth switching valve 24 or the connecting valve 26 is opened, and the air spring valves 20 and 21 are opened, and the first switching valve and the second switching valve are closed. The compressed gas in the second gas storage unit 12 can be input into the fifth pipeline 35 from the sixth pipeline 35 a and supplied to the air springs 5 ​​, 6 via the fourth pipeline 34 .

[0085] In this example, the first pipeline 31 of the gas utilization system 1 is connected to a gas source interface, which is suitable for connecting to an external gas source. The gas utilization system 1 can be quickly filled with compressed gas from the outside through the gas source interface to improve the charging efficiency of the gas utilization system 1.

[0086] In one example, refer to Figure 1 , the first pipeline 31 is provided with a throttling check valve 13. One side of the throttling check valve 13 is a one-way valve, and the other end is a throttling hole. The compressed gas output from the gas supply unit 3 can pass through the one-way valve and be input into the first gas storage unit 11, the gas receiving unit and the second gas storage unit 12. In addition, the gas in the first gas storage unit 11, the gas receiving unit and the second gas storage unit 12 can pass through the throttling hole and be discharged from the exhaust pipeline.

[0087] In one example, refer to Figure 1 The gas utilization system 1 further includes a filter 4, which is installed on the first pipeline 31. After the compressed gas output from the gas supply unit 3 is input into the first pipeline 31, it first flows into the filter 4 and then outputs from the filter 4. The filter 4 can filter impurities such as dust and particles in the compressed gas to improve the quality of the compressed gas.

[0088] In one example, refer to Figure 1The output end of the gas supply unit 3 is also connected to a deflation pipe, on which an outlet valve 14 is provided. The other end of the deflation pipe can be connected to the external atmospheric environment. When the gas supply unit 3 is overloaded during the process of compressing the gas, the second pressure sensors on both sides of the gas supply unit 3 detect that the pressure difference is too large, and the outlet valve 14 will be automatically opened, and the air in the gas supply unit 3 will be discharged into the atmosphere through the outlet valve 14.

[0089] According to another embodiment of the present application, a vehicle is provided. The vehicle includes the air utilization system of the above embodiment. For example, the air utilization system can be installed on the vehicle suspension to form an air suspension system, which can be used to adjust the height of the vehicle body. The gas utilization system 1 includes: a gas supply unit 3 and a recovery pipeline 35d. The gas outlet end of the gas supply unit 3 is connected to the first gas receiving unit 50 and the second gas receiving unit 29 through a gas supply pipeline, and the gas supply pipeline is provided with a fourth switching valve 24 between the first gas receiving unit 50 and the second gas receiving unit 29. One end of the recovery pipeline 35d is connected to the second gas receiving unit 29, and the other end is connected to the gas inlet end of the gas supply unit 3.

[0090] In this example, the fourth switching valve 24 is arranged on the gas transmission pipeline. When the fourth switching valve 24 is opened, the gas supply unit 3 can supply gas to the first gas receiving unit 50 and the second gas receiving unit 29 through the gas transmission pipeline. The second gas receiving unit 29 can also transport gas to the gas supply unit 3 for recovery through the recovery pipeline 35d. The recovery pipeline 35d can be connected to the part of the transmission pipeline located in the second gas receiving unit 29, so that the first gas receiving unit 50 can also transport gas to the recovery pipeline 35d through the gas transmission pipeline. When the fourth switching valve 24 is closed, the gas supply unit 3 can transport gas to the first gas receiving unit 50, and the second gas receiving unit 29 can transport gas to the gas supply unit 3 for recovery. The gas utilization system of the present application simplifies the pipeline connection and improves the stability of the entire gas utilization system.

[0091] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
