Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorption technology, specifically to an automotive chassis suspension shock absorber. Background Technology

[0002] With the progress of the times and the continuous development of technology, human life has become more convenient. The advent of automobiles has made travel faster. Due to the unevenness of the road surface, vibrations are often experienced during driving. In order to reduce the discomfort caused by vibrations, shock absorbers are installed at the bottom of the vehicle. Therefore, it is particularly important to propose a kind of automobile chassis suspension shock absorber.

[0003] Chinese utility model patent CN215634620U discloses a car chassis suspension shock absorber, including a base plate. A shock absorber body is fixedly mounted on the top of the base plate. A circular connecting plate is connected to the top of the shock absorber body. An auxiliary shock-absorbing mechanism is provided on the top of the connecting plate. The auxiliary shock-absorbing mechanism is connected to the car chassis via a fixing mechanism on its top. This utility model initially achieves shock absorption through the telescopic action of the telescopic rod and the elastic force of the compression spring. A sleeve rod slides onto the outer surface of the fixed rod. When the sleeve rod is under pressure, it slides downwards, compressing the buffer spring. The buffer spring further reduces the pressure on the sleeve rod, resulting in better shock absorption.

[0004] When in use, this car chassis suspension shock absorber reduces the pressure on the sleeve rod through the buffer spring to improve the shock absorption effect. However, in actual use, it still has the following defects: when facing rainy weather, the bottom is easily splashed with mud. After the mud dries inside the shock absorber, it can affect the flexibility of the shock absorber, thus affecting the shock absorption effect. Moreover, it is very inconvenient to clean, and if it is not cleaned for a long time, it can easily shorten the service life of the shock absorber. Utility Model Content

[0005] The purpose of this invention is to provide an automotive chassis suspension shock absorber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car chassis suspension shock absorber, comprising: a top cover, an oil bottle disposed at the top of the top cover, and a vent hole provided inside the top cover, the vent hole being designed in an inclined shape;

[0007] The bottom cover has an outer diameter equal to that of the top cover, and a circular groove is provided in the middle of the bottom cover.

[0017] This utility model has at least the following beneficial effects:

[0018] 1. By using the designed mud-proof structure, the top and bottom rings are installed on the outside of the buffer structure, allowing the mud-proof shell to completely cover the inside. This prevents mud splashed by the wheels from directly penetrating the interior of the buffer structure when encountering muddy roads, effectively protecting the buffer structure and extending its service life. Furthermore, when maintenance is required, the mud-proof shell can be compressed and folded by unscrewing both ends, without the need for complete removal, making it convenient and quick.
