Problems solved by technology

[0002] The shock absorber is used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. It is widely used in automobiles, electric vehicles and other fields to improve the ride comfort. The use environment of the shock absorber is relatively harsh, so shock absorption is required The shock absorber has good sealing performance, and the shock absorber needs to prevent foreign matter such as impurities and sand from entering the shock absorber during the long-term use; while the existing shock absorber has poor sealing performance, and after a period of use Impurities easily enter the shock absorber, causing damage to the shock absorber and affecting the service life of the shock absorber

Embodiment Construction

[0019] The present invention includes a handle 1 and a cylinder 3 connected to the handle 1 through a lower connecting plate 2;

[0020] The cylinder body 3 includes a handle tube 4 connected to the lower connecting plate 2, and a shock absorbing sleeve 5 socketed with the handle tube 4;

[0021] The shock-absorbing sleeve 5 and the handle 4 form a sealed connection, and a dust-proof cover 6 is arranged between the shock-absorber sleeve 5 and the handle 4, and the dust-proof cover 6 is sleeved circumferentially A sealed connection is formed outside the handle tube 4, and the dust-proof cover 6 is clamped into the inner wall of the shock absorber sleeve 5 to form a sealed connection. The dust-proof cover 5 is elastic, and the inside of the dust-proof cover 5 is inlaid There are rigid reinforcements 7;

[0022] A sealing retaining ring 8 and an oil seal 9 inside the dustproof cover 5 are also arranged between the shock absorber sleeve 5 and the handle 4 .

[0023] The rigid re...

Abstract

The invention discloses an electric vehicle shock absorber. The electric vehicle shock absorber comprises a handle rod (1) and a barrel body (3) which is connected with the handle rod (1) through a lower connecting plate (2), the barrel body (3) comprises a handle pipe which is connected with the lower connecting plate (2) and a damping sleeve (5) which sleeves the handle pipe (4), and a dustproofcover is hermetically connected with the shock absorber sleeve and the handle pipe correspondingly. According to the electric vehicle shock absorber, a dustproof cover is elastically made, and a rigid reinforcing piece is arranged inside the dustproof cover, so that the dustproof cover body is elastically arranged to enable the sealing performance of the dustproof cover is fully guaranteed; and meanwhile, due to the arrangement of the rigid reinforcing part, the dustproof cover has certain strength, and then the situations that damage is caused by overlarge deformation during compression, andthen the sealing performance is influenced are avoided.
