Shock absorber

Abstract

A damper includes two tubular bodies (1, 2), a return controller (3), a compression controller (4) and a reset device. The two tubular bodies have an open end and a close end respectively; the second tubular body (2) is inserted into and fitted with the first tubular body (1) from the open end thereof in a relatively slidable manner. Channels filled with liquid are provided in the two tubular bodies. When the second tubular body slides toward the first tubular body and then reaches a compressed position, the liquid is compressed and thus flows in the channels. The reset device includes one or more elastic member (51), elastic force of which can make the two tubular bodies back to a release position. The two controllers each can control one position of the channels, thus changing the resistance that the liquid is subjected to when it flows in the channels and adjusting the value of damping as desired.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a shock absorber with double shock absorber and damping adjustment functions which is especially suitable for a car body with a plastic shell at the front. Background technique [0002] The outside of the frame, faucet, front fork, etc. are all covered with plastic shells for scooter motorcycles. Due to the price of scooter motorcycles, the structure of the shock absorbers is roughly like that of Taiwan Patent No. TWM366483 (below Collectively referred to as the 483 case), it mainly utilizes the inner and outer cylinders that are telescopically combined to cooperate with the spring and piston in the inner cylinder to achieve the buffering and shock-absorbing effect of the road surface reaction force. Due to the simple structure of this kind of shock absorber, it is relatively impossible to adjust the damping. Therefore, the shock absorber that comes out of the factory can exert the shock absor...

AI Technical Summary

Problems solved by technology

Due to the simple structure of this kind of shock absorber, it is relatively impossible to adjust the damping. Therefore, the shock absorber that comes with the car can exert the shock absorbing effect, which is usually flat urban roads, and for forest roads or roads with slopes or roughness. Road, the shock absorber without damping adjustment effect disclosed in No. 483 cannot cope with it, so it will lead to the prosperity of the refit market. Although the shock absorber in the refit market meets the needs of various severe road surfaces, it is expensive. The price is not affordable for every consumer
