Adjustable Angle's Bicycle Seismic Isolation Device

Abstract

The utility model provides an adjustable angle's bicycle seismic isolation device, contain a buffer unit and a pivot joint, this buffer unit has a first end and a second end, this second end has a terminal surface, one by this terminal surface towards the concave depressed part of establishing of this first end, one sets up in this depressed part and along pin joint portion that a central line extends and one around this central line and set up in the indent cambered surface of this depressed part inner end, this pivot joint has one and is the circular -arc pivot face of evagination, this pivot face can rotate and laminate in this indent cambered surface. When a connecting rod parts produces the pivot for a lower fork part, utilize this pivot face can rotate and laminate in the effect of this indent cambered surface, enable the shaking force and stretch the direction corresponding to an axis edge of this buffer unit, and can produce the buffering effect of preferred.

Description

technical field [0001] The invention relates to a bicycle accessory, in particular to an angle-adjustable bicycle shock absorber. Background technique [0002] Generally, for a bicycle with a front shock absorber function, at least one front shock absorber is installed on an inverted Y-shaped front fork, so that when a front wheel vibrates due to bumps in the road surface, the front shock absorber passes through the front fork. Can reach the purpose of front wheel shock absorber and cushioning (such as the patent cases such as No. M526977, No. 525317, No. 522173 of Chinese Taiwan certificate number). [0003] Additionally, if figure 1 As shown, there is a bicycle with a front shock absorber function, which includes a main frame 1, a front fork unit 2 pivotally connected to the main frame 1, and a front shock absorber mounted on the front fork unit 2 3. The main frame 1 includes a head tube 101, the front fork unit 2 includes a top tube 201 with a shaft set on the head tube...

AI Technical Summary

Problems solved by technology

[0006] Although this front shock absorber 3 can produce the function of buffering and shock absorbing, because at the moment of shock, the top of the connecting rod 203 is a swing that produces a circular arc track relative to the lower fork 202, so that the The spring 301 will be driven to arch upwards, therefore, the shock force cannot be accurately transmitted and corresponds to the axial direction of the spring 301, and the resulting shock absorbing and buffering effect will be affected
