Muddy water preventing structure of air spring electromagnetic valve

Abstract

According to the muddy water prevention structure of the air spring electromagnetic valve, a sealing cover is arranged above the electromagnetic valve, and the sealing cover is matched with an upper layer structure of an upper air chamber to prevent muddy water from making contact with the electromagnetic valve; the sealing cover comprises a first tension layer and a second tension layer, the first tension layer and the second tension layer can be independently used for sealing the electromagnetic valve, so that the sealing and muddy water preventing effects are good, and the acting force of the first tension layer and the upper air chamber upper layer structure is smaller than that of the second tension layer and the upper air chamber upper layer structure. When the double-cavity air spring encounters strong vibration and contraction deformation, the first tension layer deforms earlier than the second tension layer, so that vibration and contraction caused by the upper-layer structure of the upper air chamber are absorbed through deformation, and the second tension layer is always attached to the upper-layer structure of the upper air chamber; therefore, muddy water is prevented from entering and penetrating through the second tension layer to contact with the electromagnetic valve.

[0002] Double-chamber air springs are generally used in automobiles. Their structure mainly includes two upper and lower air chambers, and a solenoid valve arranged between the upper and lower air chambers and used to control the opening and closing of the air path between the two air chambers; wherein, the upper air chamber is surrounded by the upper air chamber upper structure, the upper air chamber lower structure and the solenoid valve, and the upper end of the solenoid valve is fixed to the upper air chamber upper structure, and the lower end is fixed to the upper air chamber lower structure.

[0003] In the prior art, the mud and water prevention structure of the double-chamber air spring generally includes a sealing cover arranged on the solenoid valve, which prevents mud and water from contacting the solenoid valve through the cooperation between the sealing cover and the upper structure of the upper air chamber; but during the use of the automobile, the double-chamber air spring is often subjected to strong vibration and contraction deformation, which may cause the cooperation between the sealing cover and the upper structure of the upper air chamber to loosen and produce a gap, and the mud and water will pass through the gap between the solenoid valve and the upper structure of the upper air chamber, so that the gap between the two increases and causes the sealing failure of the upper air chamber, thereby causing the air spring to fail.

[0031] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.

[0032] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0033] See also Figure 1-6The air spring solenoid valve anti-mud and water structure shown includes an upper air chamber upper structure 1, a solenoid valve 2 and a sealing cover 4; wherein the solenoid valve 2 is fixed to the upper air chamber upper structure 1; wherein the solenoid valve block 3 is arranged on the upper air chamber upper structure 1, for fixing the solenoid valve 2; wherein the sealing cover 4 is arranged above the solenoid valve 2; the sealing cover 4 includes a first tension layer 41 and a second tension layer 42 arranged up and down; the first tension layer 41 and the second tension layer 42 are arranged to be interference fit with the upper air chamber upper structure 1 to prevent mud and water from contacting the solenoid valve 2; the force between the first tension layer 41 and the upper air chamber upper structure 1 is set to be smaller than the force between the second tension layer 42 and the upper air chamber upper structure 1, so that the first tension layer 41 is deformed before the second tension layer 42 during vibration.

[0034] In actual use, the utility model is provided with a sealing cover 4 above the solenoid valve 2, and the sealing cover 4 cooperates with the upper air chamber upper structure 1 to prevent mud and water from contacting the solenoid valve 2; wherein, the sealing cover 4 includes a first tension layer 41 and a second tension layer 42, and the first tension layer 41 and the second tension layer 42 can be used separately for sealing the solenoid valve 2, so the sealing and mud and water prevention effects are better, and the force between the first tension layer 41 and the upper air chamber upper structure 1 is less than the force between the second tension layer 42 and the upper air chamber upper structure 1. When the double-chamber air spring encounters strong vibration and contraction deformation, the first tension layer 41 deforms before the second tension layer 42, so as to absorb the vibration and contraction caused by the upper air chamber upper structure 1 through deformation, and keep the second tension layer 42 and the upper air chamber upper structure 1 always in contact, thereby preventing mud and water from entering through the second tension layer 42 and contacting the solenoid valve 2.

[0035] Please continue reading Figure 2 , Figure 3 , wherein the first tension layer 41 includes a deformable valve 411 and a radial accommodating space 412 surrounded by the deformable valve 411; the radial accommodating space 412 is used to withstand the radial deformation of the deformable valve 411.

[0036] Specifically, when the upper structure 1 of the upper air chamber vibrates or deforms along the diameter, the deformable valve 411 can be squeezed along the A direction to the radial accommodating space 412 to absorb the vibration or deformation, and the second tension layer 42 with greater tension can be protected and always fit with the upper structure 1 of the upper air chamber, so that muddy water is not easy to pass through the second tension layer 42 and contact the solenoid valve 2.

[0037] Please continue reading Figure 4 , Figure 5In other embodiments, the deformable valve 411 has an outer side surface 4111, an inner side surface 4112 and at least one axial accommodating space 4113; the axial accommodating space 4113 is arranged at at least one of the outer side surface 4111 and the inner side surface 4112, and is used to withstand the axial deformation of the deformable valve 411.

[0038] Specifically, when the upper air chamber upper structure 1 vibrates or deforms in the axial direction, the deformation valve 411 can shrink along the B direction to absorb the vibration or deformation, and the second tension layer 42 with greater tension can be protected and always fit with the upper air chamber upper structure 1, so that muddy water is not easy to pass through the second tension layer 42 and contact the solenoid valve 2.

[0039] It is understandable that the first tension layer 41 can also be set to a different material from the second tension layer 42, and the tension of the first tension layer 41 is less than that of the second tension layer 42. By setting materials with different tensions, the first tension layer 41 can also be deformed before the second tension layer 42.

[0040] Please continue reading Figure 2 In some embodiments, the first tension layer 41 is disposed above the second tension layer 42 , and the second tension layer 42 is in contact with the upper end surface of the solenoid valve 2 .

[0041] Please continue reading Figure 1 , Figure 6 , including a solenoid valve block 3 and a first sealing ring 5; wherein the solenoid valve block 3 is arranged on the upper air chamber upper structure 1, for fixing the solenoid valve 2; the second tension layer 42 has at least one annular accommodating portion 421; the first sealing ring 5 is arranged in the annular accommodating portion 421.

[0042] By setting the solenoid valve block 3, the connection between the upper end of the solenoid valve 2 and the upper air chamber upper structure 1 is made tighter. When the double-chamber air spring encounters strong vibration and contraction deformation, the solenoid valve block 3 can prevent the solenoid valve 2 from loosening, avoiding the two from loosening or lifting the sealing cover 4 to allow mud and water to enter; and the setting of the annular accommodating portion 421 and the first sealing ring 5 makes the anti-mud and water effect better.

[0043] Please continue reading Figure 6 , wherein the annular accommodating portion 421 is arranged at the bottom of the second tension layer 42; when the first sealing ring 5 is arranged in the annular accommodating portion 421, it is squeezed by the annular accommodating portion 421, the upper air chamber upper structure 1 and the solenoid valve stopper 3.

[0044] Under this arrangement, it is more conducive to exerting the sealing effect of the first sealing ring 5 so as to cover the three gaps where mud and water may penetrate, namely, the gaps between the annular accommodating portion 421 and the upper air chamber upper structure 1, the gaps between the upper air chamber upper structure 1 and the solenoid valve stopper 3, and the gaps between the solenoid valve stopper 3 and the annular accommodating portion 421.

[0045] Please continue reading Figure 6 , wherein the upper air chamber upper structure 1 includes a conical portion 11, a transition portion 12 and a covering portion 13 arranged in sequence from top to bottom; the sealing cover 4 is arranged to cooperate with the conical portion 11; the solenoid valve block 3 is arranged to cooperate with the transition portion 12; and the side wall of the solenoid valve 2 is arranged to cooperate with the covering portion 13.

[0046] Please read further Figure 6 , and also includes a second sealing ring 6; the solenoid valve 2 has a sealing groove 21; the second sealing ring 6 is arranged in the sealing groove 21; the conical portion 11 has at least one reinforcement groove 111 arranged along the axial direction, and the sealing cover 4 includes at least one reinforcement block 43 arranged along the circumferential direction; the reinforcement block 43 is arranged to be embedded in the reinforcement groove 111.

[0047] The structural design of the conical portion 11, the transition portion 12 and the covering portion 13 of the upper air chamber upper structure 1 facilitates the installation and fixation of the solenoid valve block 3 and the solenoid valve 2; a second sealing ring 6 is added to the sealing groove 21, so that the anti-mud and water effect of the utility model is further guaranteed; through the coordinated design of the fixing block 43 and the reinforcement groove 111, when the double-chamber air spring encounters strong vibration and contraction deformation, the solenoid valve block 3 is restricted and cannot rotate loose, so that mud and water are not easy to penetrate.

[0048] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
