Description

Wireless Control Bicycle Front Fork Hydraulic Damping Suspension System

technical field

The invention is related to the shock absorption of the bicycle front fork, in particular to a wireless control bicycle front fork oil pressure damping shock absorption system capable of wirelessly controlling the oil pressure damping effect.

Background technique

The bicycle mainly relies on the shock absorber in the process of driving to reduce the shock from the road surface and reduce the fatigue and discomfort of the rider, especially in the 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.

Shock absorbers such as Taiwan's new patent M602994 bicycle air shock absorber, M536300 gas shock absorber, China's new patent CN209067742U for rebound damping of bicycles, and Taiwan's invention patent I413601 for the spring suspension of the handlebar-operated vehicle , US Patent US10668975B2 Shock device in particular forbicycles, US Patent US10337584B2 Bicycle fork having lock-out, blow-off, and adjustable blow-off threshold, from the above-mentioned front fork shock absorber, it can be understood that the use of air pressure, oil pressure, spring, etc. alone or Composite 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, making it impossible 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.
