[0002] As market demands for passenger vehicle ride quality diversify, more adjustable air spring stiffness is becoming a necessity. Air springs, through internal structural design, are divided into a primary and secondary chamber. In addition to all the components of a conventional single-chamber assembly, they incorporate a solenoid valve. Opening and closing the solenoid valve adjusts the volume of air involved in the spring's operation, thereby adjusting the spring's stiffness characteristics. The solenoid valve is connected to an external control system via a wiring harness connector that controls its opening and closing.

[0003] The solenoid valve wiring harness is mostly built into the undulating piston, and the solenoid valve body end is placed on the piston end face, relying on the solenoid valve body end tail and the upper mounting pad to prevent environmental mud and water from entering the piston during vehicle operation, causing the solenoid valve performance failure. However, the solenoid valve body end tail and the mounting pad make it impossible to adjust the length of the wiring harness. Utility Model Content

The wiring harness 1 passes through the dustproof pad 2, and the mounting pad 3 is used to abut the dustproof pad 2 so that the dustproof pad 2 is sealed and connected to the air spring 4.

[0023] Specifically, a wiring harness hole 201 is opened on the dustproof pad 2, and the wiring harness 1 passes through the wiring harness hole 201. The inner wall of the wiring harness hole 201 is provided with multiple circles of rib structures 202. In this embodiment, two circles of rib structures 202 are provided, and the rib structures 202 are wrapped tightly around the outer wall of the wiring harness 1.

[0024] The dustproof pad 2 is pressed tightly by the installation pad 3, and the rib structure 202 on the inner wall of the wiring harness hole 201 is in close contact with the wiring harness 1, thereby realizing a sealed connection between the dustproof pad 2 and the air spring 4. During the operation of the vehicle and on wading roads, it can also effectively prevent the infiltration of mud and sand, greatly reducing the risk of infiltration into the air spring 4 and avoiding failure of the solenoid valve performance; and the dustproof pad 2 is not integrally injection molded with the wiring harness 1, so that the dustproof pad 2 can be set at any position of the wiring harness 1 to realize the adjustment of the length of the wiring harness 1 on the solenoid valve.

[0025] The outer wall of the dustproof pad 2 is also provided with a first limiting boss 21, which is symmetrically arranged on the outer walls on both sides of the top of the dustproof pad 2, so that the dustproof pad 2 can be clamped on the air spring 4, and plays a radial limiting role on the dustproof pad 2 to prevent it from moving. The dustproof pad 2 is axially pressed against the mounting pad 3 for limitation.

[0026] The top of the dustproof pad 2 is horizontal and fits with the bottom of the mounting pad 3 . The bottom of the dustproof pad 2 is arc-shaped and fits with the air spring 4 .

Specifically, the first limiting boss 21 is clamped on the air spring 4, and then the mounting pad 3 is clamped on the air spring 4. Specifically, the second limiting boss 31 is clamped on the air spring 4, and at the same time the mounting pad 3 presses the dustproof pad 2, which not only makes the dustproof pad 2 and the air spring 4 sealed and connected, but also makes the rib structure 202 on the inner wall of the wiring harness hole 201 close to the wiring harness 1, and can effectively prevent the infiltration of mud and sand during vehicle operation and on wading roads, greatly reducing the risk of infiltration into the air spring 4 and avoiding failure of the solenoid valve performance; and the dustproof pad 2 is not integrally injection molded with the wiring harness 1, so that the dustproof pad 2 can be set at any position of the wiring harness 1 to achieve adjustment of the length of the wiring harness 1 on the solenoid valve.
