Description

Wireless Control Bicycle Front Fork Hydraulic Damping Suspension System

The present invention is related to the shock absorber of the bicycle front fork, especially the one that can wirelessly control the oil pressure damping effect.

The bicycle mainly relies on the shock absorber in the process of driving to reduce the shock from the road surface, reduce the fatigue and discomfort of the rider, especially in rough road conditions (mountain road or suburban), the effect is more significant. Many cyclists love adventure and drive on winding roads and non-paved roads, and they are bound to face more uneven roads or roads with complex roads (the road has gravel and dirt). The high-frequency vibration reduces the burden and fatigue transmitted to the rider's muscles, and can increase the driving comfort, and has sufficient spare force to keep the vehicle stable, so the shock absorber is an important part of the bicycle's driving comfort and stability.

For example, the shock absorbers include the Taiwan new patent M602994 bicycle air shock absorber, the M536300 gas shock absorber, the Chinese new patent CN209067742U for the rebound damping of the bicycle, the Taiwan invention patent I413601 for the spring suspension of the handle bar to control the vehicle, U.S. Patent US10668975B2 Shock device in particular for bicycles, U.S. Patent US10337584B2 Bicycle fork having lock-out, blow-off, and adjustable blow-off threshold, from the above front fork shock absorbers can be understood that there are separate use of air pressure, oil pressure, spring, etc. or combined use.

However, the damping adjustment of the above-mentioned shock absorber needs to be adjusted appropriately according to the model and road conditions, so the operation is quite troublesome, and even requires additional tools, which makes it difficult for ordinary bicycle enthusiasts to adjust conveniently and quickly. Moreover, in a non-competitive state, cyclists will not frequently perform fine-tuning of the front fork shock absorber in response to road conditions, so that the effect of the above shock absorber cannot be performed as expected.
