A dust-proof automobile airbag shock absorber

Abstract

The invention discloses a dustproof air-bag shock absorber for cars. The dustproof air-bag shock absorber comprises a first dustproof cover. One end of the first dustproof cover is provided with a first adapter. An outer cylinder is arranged in the first dustproof cover. One end of the outer cylinder is connected with the first adapter. A shock absorption spring is arranged between a support ring and the first dustproof cover, and a second dustproof cover is arranged outside the spring. The dustproof air-bag shock absorber has the advantages that the shock absorber is provided with a first piston cylinder, the spring, a second piston cylinder, the first dustproof cover and the second dustproof cover, primary pressure reduction is achieved through the first piston cylinder, shock can be absorbed preliminarily through the spring, secondary shock absorption can be achieved through the second piston cylinder, the first dustproof cover and the second dustproof cover completely cover the whole shock absorber and well protect the shock absorber, the shock absorber uses air pressure to absorb shock, good shock absorption effect is achieved, and the shock absorber is simple in structure, high in practicality and good in dustproof effect.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a dust-proof automobile airbag shock absorber. Background technique [0002] The shock absorber is mainly used to suppress the shock when the shock absorbing spring rebounds after absorbing the shock and the impact from the road surface. When passing through an uneven road surface, the existing shock absorber includes a working cylinder. A connecting rod is arranged in the working cylinder and protrudes from one end of the working cylinder. The working cylinder is located at the port where the connecting rod extends out of the working cylinder. The connection between the guide and the connecting rod is in a bare state relative to the outside world. After a long time of use, the functions of the guide and a part of the connecting rod will be damaged, and the service life of the shock absorber will be reduced. With the improvement of people's living standards, cars have become p...

AI Technical Summary

Problems solved by technology

When passing through an uneven road surface, although the shock-absorbing shock-absorbing spring can filter the vibration of the road surface, the shock-absorbing spring itself will have reciprocating motion, and the shock absorber is used to suppress the jump of this shock-absorbing spring. It will jump up and down, and if the shock absorber is too hard, it will bring too much resistance, which will hinder the normal work of the shock absorber. In the modification process of the suspension system, hard shock absorbers should be matched with hard shock absorbers. The hardness of the shock absorbing spring is closely related to the weight of the car, so a heavier car generally adopts a harder shock absorber. The prior art such as the Chinese invention patent of CN201220676684 discloses a kind of dustproof effect shock absorber, but this kind of shock absorber has low dust-proof effect and poor practicability. For this reason, we propose a dust-proof automobile airbag shock absorber
