Description

Wireless control bicycle front fork hydraulic damping shock absorber system

The invention relates to the shock absorber of the front fork of a bicycle, and particularly refers to the one that can wirelessly control the hydraulic damping effect.

During the bicycle driving process, it mainly relies on shock absorbers to reduce the shock from the road surface and reduce the fatigue and discomfort of the rider. The effect is more significant especially on rugged road conditions (mountain roads or suburbs). Many bicycle enthusiasts like to take risks and drive on winding roads and unpaved roads. They are bound to face more uneven roads or roads with complex roads (the road has gravel and mud). The shock absorber eliminates the small, even High-frequency vibration reduces the burden and fatigue transmitted to the muscles of the rider, and can increase the comfort of driving, and there is sufficient spare power to maintain the stability of the vehicle. Therefore, the shock absorber is an important part of the comfort and stability of the bicycle.

Shock absorbers such as Taiwan's new patent M602994 bicycle pneumatic shock absorber, M536300 gas shock absorber, China's new patent CN209067742U for rebound damping of bicycles, Taiwan invention patent I413601 for the spring suspension of handle lever control vehicles, 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-mentioned front fork shock absorbers, it can be understood that air pressure, oil pressure, springs, etc. are used separately Or combined use.

However, the damping adjustment of the above-mentioned shock absorber needs to be adjusted appropriately according to the vehicle model and road conditions, so the operation is quite troublesome and even requires additional tools, which makes it impossible for ordinary cyclists to adjust conveniently and quickly. Moreover, in the non-competitive state, cyclists will not frequently fine-tune the front fork shock absorbers according to the road conditions, so that the effectiveness of the above shock absorbers cannot be exerted as expected.

This creation provides convenient and rapid adjustment of the shock absorber effect of the hydraulic damping of the front fork of the bicycle, and adopts the technical means of wireless control of the hydraulic damping of the front fork.

In order to achieve the foregoing objectives and effects, the present invention provides a wireless control bicycle front fork hydraulic damping shock absorber system, which includes a front fork and a control device, wherein: the front fork includes a sleeve assembly and a damping adjustment unit; The sleeve assembly includes an upper tube body, a lower tube body, and an inner tube body. The upper tube body and the lower tube body are movably connected to each other, and the inner tube body is disposed between the upper tube body and the lower tube body. The damping adjustment unit is assembled in the upper tube, the damping adjustment unit includes a damping control valve and the inner tube is divided into an upper chamber and a lower chamber, the upper chamber is filled with gas, the The lower chamber is filled with hydraulic oil, the damping control valve has a flow hole and communicates with the upper chamber and the lower chamber; the damping adjustment unit includes a driving module, and a spindle of the driving module is located in the upper chamber Toward the orifice direction; the control device includes an operating interface, the operating interface includes a setting page and a home page; the setting page is configured to wirelessly link the damping adjustment unit, and a mode block of the home page includes only a comfort Suspension, a soft suspension and a strong shock, and the comfortable shock, the soft shock and the strong shock are respectively set to control the rotation of the spindle, so that the spindle drives a control of a valve stem The end systems are respectively far away, close to and closed the orifice state, so as to change the liquid The flow rate of the pressure oil flowing from the lower chamber to the upper chamber achieves the control of the compression damping of the front fork.
