[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] In the automobile air suspension system, the inlet and outlet of gas is generally controlled by a one-way valve, thereby controlling the height of the air suspension system. When the height of the vehicle body needs to be increased, the one-way valve allows gas to enter the suspension system, increase the air pressure, and thus raise the vehicle body. When the height of the vehicle body needs to be lowered, the one-way valve is closed to prevent the gas from flowing in, thereby reducing the air pressure and lowering the vehicle body. In the related art, the one-way valve generally includes a ball, a spring and a valve seat, wherein the ball and the spring constitute a valve mechanism, and the gas flow is controlled by opening and closing the valve mechanism, but the one-way valve has a complex structure and many parts, and is easy to damage. Compared with the prior art, the one-way valve of the automobile air suspension is simple and reliable in structure, and is easy to manufacture and maintain; at the same time, the valve seat is divided into an air inlet part and an air outlet part to ensure that the gas can only flow in one direction, thereby ensuring the normal operation of the one-way valve; in addition, the first air pipe joint and the second air pipe joint are connected to the valve seat by a snap connection method to ensure that the air pipe joint and the valve seat can be firmly connected and reduce the risk of gas leakage.

[0035] like Figures 1 to 4 As shown, an embodiment of the present application provides a one-way valve for an automobile air suspension, comprising: a valve seat 100 , a first air pipe joint 200 , a second air pipe joint 300 and a valve 400 .

[0036] The valve seat 100 includes an air inlet portion 110 and an air outlet portion 120 connected to each other, the air inlet portion 110 has a first interface channel 111 and an air inlet channel 112 connected to each other, the air outlet portion 120 has a second interface channel 121 and an air outlet channel 122 connected to each other, and the air inlet channel and the air outlet channel are configured to be connected to the valve block respectively; a first air pipe joint 200 is snap-connected to the air inlet portion 110 and penetrated in the first interface channel 111; a second air pipe joint 300 is snap-connected to the air outlet portion 120 and penetrated in the second interface channel 121; and a valve 400 is movably arranged on one side of the valve seat 100 corresponding to the air inlet channel 112.

[0037] The valve seat 100 may further include a mounting portion, which is respectively connected to the air inlet 110 and the air outlet 120, and is used to connect to the valve block. Specifically, the mounting portion has a mounting hole, and a mounting screw is inserted through the mounting hole and connected to the valve block.

[0038] The air inlet portion 110 and the air outlet portion 120 are substantially cylindrical, which makes the overall appearance of the one-way valve smooth and saves space.

[0039] like Figures 1 to 4 As shown, the valve 400 corresponds to the intake passage 112 and is located in the valve block.

[0040] like Figures 1 to 4As shown, the outer peripheral surface of the air inlet portion 110 has a first annular groove 113, and a first sealing ring 114 is disposed in the first annular groove 113. The first sealing ring 114 can increase the sealing performance of the one-way valve and prevent gas leakage.

[0041] like Figures 1 to 4 As shown, the outer circumferential surface of the air inlet portion 110 is provided with a first protrusion 115 and a second protrusion 116 at intervals, a first clamping groove is formed between the first protrusion 115 and the second protrusion 116, and the first air pipe joint 200 is clamped in the first clamping groove.

[0042] The first protrusion 115 and the second protrusion 116 are both arranged around the outer peripheral surface of the air inlet 110, and the outer edge surface of the first protrusion 115 gradually tilts outward from top to bottom, so that the connection stability between the first air pipe joint 200 and the air inlet 110 can be improved. When the first clamping portion 240 described below enters the first clamping groove, the end clamping block of the first clamping portion 240 needs to be pulled outward to make the first clamping portion 240 disengage from the first clamping groove.

[0043] like Figures 1 to 4 As shown, the first air pipe joint 200 includes a first disc portion 210, a first air pipe connecting portion 220, a first plug portion 230 and a first clamping portion 240. The first disc portion 210 abuts against the air inlet portion 110. The first air pipe connecting portion 220 is arranged on the surface of the first disc portion 210 facing away from the air inlet portion 110. The first plug portion 230 is arranged on the surface of the first disc portion 210 facing the air inlet portion 110. The first plug portion 230 is penetrated through the first interface channel 111. The first clamping portion 240 is connected to the first disc portion 210 and is located on the same side of the first plug portion 230. The end clamping block of the first clamping portion 240 is clamped in the first clamping groove.

[0044] like Figures 1 to 4 As shown, the bottom of the gas outlet portion 120 has a second annular groove 123, and a second sealing ring 124 is disposed in the second annular groove 123. The second sealing ring 124 can increase the sealing performance of the one-way valve to prevent gas leakage.

[0045] like Figures 1 to 4 As shown, the outer circumferential surface of the air outlet portion 120 is provided with a third protrusion 125 and a fourth protrusion 126 at intervals, and a second clamping groove is formed between the third protrusion 125 and the fourth protrusion 126, and the second air pipe connector 300 is clamped in the second clamping groove.

[0046] The third protrusion 125 and the fourth protrusion 126 are both arranged around the outer peripheral surface of the air inlet portion 110, and the outer edge surface of the third protrusion 125 gradually tilts outward from top to bottom, so that the connection stability between the second air pipe joint 300 and the air outlet portion 120 can be improved. When the second clamping portion 340 described below enters the second clamping groove, the end clamping block of the second clamping portion 340 needs to be pulled outward to make the second clamping portion 340 disengage from the second clamping groove.

[0047] like Figures 1 to 4 As shown, the second air pipe joint 300 includes a second disc portion 310, a second air pipe connecting portion 320, a second plug portion 330 and a second clamping portion 340. The second disc portion 310 abuts against the air outlet portion 120. The second air pipe connecting portion 320 is arranged on the surface of the second disc portion 310 facing away from the air outlet portion 120. The second plug portion 330 is arranged on the surface of the second disc portion 310 facing the air outlet portion 120. The second plug portion 330 is penetrated through the second interface channel 121. The second clamping portion 340 is connected to the second disc portion 310 and is located on the same side of the second plug portion 330. The end clamping block of the second clamping portion 340 is clamped in the second clamping groove.

[0048] See also Figure 5 When air is inhaled, the gas enters the air inlet passage through the first air pipe joint. At this time, due to the effect of air pressure, the valve opens, that is, the valve is not in contact with the air inlet part, so that the gas can smoothly enter the valve block.

[0049] See also Figure 6 When deflation or no air intake occurs, the valve is closed due to air pressure, that is, the valve contacts the air intake portion, thereby closing the air intake passage. In this way, the gas in the valve block cannot enter the air intake passage.
