Description

Technical Field

[0001] This utility model relates to the field of air suspension technology, and in particular to an air suspension dust cover that is easy to maintain. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for automotive comfort, air suspension systems have gradually become standard equipment in high-end models and vehicles for specific purposes (such as commercial vehicles, buses, and luxury cars). Air suspension systems adjust the vehicle height and damping effect by regulating the air pressure in the airbags, thereby providing a smoother and more comfortable driving experience.

[0003] Traditional air suspension dust covers are prone to deformation, aging, or damage during long-term use, leading to a decline in sealing performance. Therefore, dust cover maintenance is required. However, the existing dust cover installation process is relatively complicated and requires large-scale disassembly of the entire air suspension, making the maintenance process difficult and increasing maintenance time. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of complicated and time-consuming disassembly of air suspension dust covers during maintenance. Therefore, we propose an air suspension dust cover that is easy to maintain.

[0005] To achieve the above objectives, this application adopts the following technical solution: an easy-to-maintain air suspension dust cover, comprising a dust cover body, with shafts at both ends of the dust cover body, and a first end cap and a second end cap rotatably connected to both sides of the shafts. An airbag is placed inside the dust cover body. A first housing is fixed to one end of the first end cap, and a second housing is fixed to one end of the second end cap. A knob is threadedly connected inside the second housing. A limit block is fixed to one end of the knob inside the second housing. Moving plates are slidably connected to both sides inside the second housing. A fixing block is fixed to one end of each moving plate. Fixing grooves that cooperate with the fixing blocks are opened at both ends of the first housing.

[0006] Preferably, a return spring is fixed on both sides inside the second housing, and the other end of the return spring is fixed to the moving plate.

[0007] Preferably, limit rods are fixed on both sides inside the second housing, and a limit groove is formed on the surface of the movable plate to cooperate with the limit rods.

[0008] Preferably, the limiting block is elliptical in shape.

[0009] Preferably, the surface of the knob is provided with an anti-slip pad, and the anti-slip pad is made of rubber.

[0010] Preferably, a sealing gasket is provided on the opposite surfaces of the first end cap and the second end cap.

[0011] Preferably, the dust cover body is made of thermoplastic polyester elastomer material, which has excellent aging resistance, wear resistance and corrosion resistance.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by turning the knob, the fixed limiting block is rotated, causing the limiting block to move away from the moving plate. Then, the moving plate is pushed by the return force of the reset spring, which takes the fixed block away from the inside of the fixing groove, releasing the fixation between the airbag and the first housing. At the same time, the user can rotate the first end cover or the second end cover to release the tight connection with other components, so that the dust cover body can be removed from the airbag for maintenance. There is no need to disassemble the entire air suspension on a large scale, which reduces the maintenance difficulty and time cost. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: an easy-to-maintain air suspension dust cover, including a dust cover body 1, with shafts 2 at both ends of the dust cover body 1, and a first end cap 3 and a second end cap 4 rotatably connected to both sides of the shafts 2. An airbag 5 is placed inside the dust cover body 1. A first housing 6 is fixed to one end of the first end cap 3, and a second housing 7 is fixed to one end of the second end cap 4. A knob 8 is threadedly connected inside the second housing 7, and a limit block 9 is fixed to one end of the knob 8 inside the second housing 7. Moving plates 10 are slidably connected to both sides inside the second housing 7, and a fixing block 11 is fixed to one end of the moving plate 10. Both ends of the first housing 6 are provided with openings that match the fixing blocks 11. The fixed groove 12 is used in conjunction with the second housing 7. Both sides of the second housing 7 are fixed with return springs 13. The other end of the return spring 13 is fixed with the moving plate 10. By turning the knob 8, the fixed limiting block 9 is rotated, so that the limiting block 9 moves away from the moving plate 10. Then, the moving plate 10 is pushed by the rebound force of the return spring 13 to take the fixed block 11 away from the inside of the fixed groove 12, thereby releasing the fixation between the airbag 5 and the first housing 6. At the same time, the user can rotate the first end cover 3 or the second end cover 4 to release the tight connection with other components, so that the dust cover body 1 can be removed from the airbag 5 for maintenance. There is no need to disassemble the entire air suspension on a large scale, which reduces the maintenance difficulty and time cost.

[0021] Reference Figure 4 As shown in this embodiment: Limiting rods 14 are fixed on both sides inside the second housing 7, and a limiting groove 15 is provided on the surface of the moving plate 10 to cooperate with the limiting rods 14. Through the structure of the limiting rods 14 and the limiting groove 15, the moving direction of the moving plate 10 can be restricted, so as to avoid the phenomenon of the moving plate 10 deviating during the movement and ensure the stability of the moving plate 10 when it moves.

[0022] Reference Figure 4 As shown in this embodiment: the limiting block 9 is elliptical in shape. The elliptical limiting block 9 can reduce the contact area between itself and the moving plate 10, thereby reducing the friction between the limiting block 9 and the moving plate 10 when rotating, so that the limiting block 9 can rotate more smoothly. In addition, the elliptical nature of the limiting block 9 allows the moving plate 10 to completely remove the fixing block 11 from the inside of the fixing groove 12.

[0023] Reference Figure 4 As shown in this embodiment: the surface of the knob 8 is provided with an anti-slip pad 16, which is made of rubber. By setting the anti-slip pad 16 and combining it with the characteristics of its rubber material, the firmness between the knob 8 and the second housing 7 can be further improved, and loosening can be avoided.

[0024] Reference Figure 3As shown in this embodiment, sealing gaskets 17 are provided on the opposite surfaces of the first end cover 3 and the second end cover 4. By providing sealing gaskets 17 on the opposite surfaces of the first end cover 3 and the second end cover 4, the tight connection between the dust cover body 1 and other components of the air suspension can be ensured, preventing dust, moisture and other impurities from entering the suspension system, thereby improving the stability and service life of the air suspension.

[0025] Reference Figure 1 As shown in this embodiment, the dust cover body 1 is made of thermoplastic polyester elastomer material, which has excellent aging resistance, wear resistance and corrosion resistance. By using thermoplastic polyester elastomer material for the dust cover body 1, stable performance can be maintained under harsh working conditions. It can also improve the impact resistance of the dust cover body 1 and prevent it from cracking or being damaged when subjected to external forces.

[0026] Working principle: By turning knob 8, the user rotates the fixing block 9, moving it away from the moving plate 10. The moving plate 10, pushed by the return spring 13, then pulls the fixing block 11 away from the fixing groove 12, releasing the fixation between the airbag 5 and the first housing 6. Simultaneously, the user can rotate the first end cover 3 or the second end cover 4 to release the tight connection with other components, allowing the dust cover body 1 to be removed from the airbag 5 for maintenance. This eliminates the need for extensive disassembly of the entire air suspension, reducing maintenance difficulty and time costs. The structure of the limiting rod 14 and the limiting groove 15 restricts the movement direction of the moving plate 10, preventing deviation during movement and ensuring stability. The elliptical limiting block 9 reduces the contact area with the moving plate 10, thus reducing the size of the limiting block. The friction between the limit block 9 and the moving plate 10 during rotation allows the limit block 9 to rotate more smoothly. The elliptical shape of the limit block 9 also allows the moving plate 10 to completely remove the fixed block 11 from the inside of the fixed groove 12. The anti-slip pad 16, combined with the properties of its rubber material, further enhances the firmness between the knob 8 and the second housing 7, preventing loosening. By setting a sealing gasket 17 on the opposite surfaces of the first end cover 3 and the second end cover 4, a tight connection between the dust cover body 1 and other components of the air suspension can be ensured, preventing dust, moisture, and other impurities from entering the suspension system, thereby improving the stability and service life of the air suspension. By using thermoplastic polyester elastomer material for the dust cover body 1, stable performance can be maintained under harsh working conditions, and the impact resistance of the dust cover body 1 can be improved, preventing it from cracking or being damaged when subjected to external forces.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
