Description

Damping device for bicycle

Technical Field

The utility model relates to the field of bicycle damping devices, in particular to a bicycle damping device.

Background

At present, bicycles are widely seen in life, the bicycles with higher grade are generally provided with damping devices, the main effect of the dampers is that wheels can be attached to the road surface to move when people ride on the rugged road, and the rest parts of the bicycle can not move greatly due to the dampers (of course, the bicycle tire can fully absorb impact on the road section with little fluctuation). The shock absorber greatly reduces the effects of hollowness and jolting through compression and expansion. They also have a damping effect and will expand relatively slowly back to their original position after compression (rather than "straight in" as a spring does).

But currently the means for rear wheel shock absorption are for example: CN97210659.6, a bicycle rear wheel shock absorber, and specifically discloses a bicycle frame riser, a rear wheel fork diagonal bracing, a rear wheel and a A, B, C hinge. A shock absorber is arranged between the rear wheel fork diagonal bracing and the frame vertical pipe, so that the rear wheel moves up and down under the actions of the shock absorber and three hinges. The exposed shock absorber is easy to corrode and damage and is broken, the rear wheel diagonal brace of the wheel is directly connected with the shock absorber, and other acting forces such as impact and deflection of the rear wheel diagonal brace can directly act on the shock absorber, so that the shock absorber is easy to damage.

Disclosure of Invention

In order to solve the problems, the utility model provides a bicycle damping device which can hide a damper, avoid the impact and offset actions of other parts from being transferred to the damper, protect the damper and prevent the damper from being damaged easily.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a bicycle damping device, includes the frame, locates the well pipe on the frame, well pipe is located between seat and the footboard, be equipped with the bumper shock absorber of vertical slope in the well intraductal, well pipe left side is equipped with vertical left through-hole, well pipe right side is equipped with vertical right through-hole, the middle part of well pipe top articulated first articulated piece, right-hand member of first articulated piece wears out right through-hole upper portion articulated bumper shock absorber top, left end of first articulated piece wears out left through-hole upper portion articulated first long frame's right-hand member, the left end of first long frame downward sloping articulates the left end of second long frame, the second long frame level sets up, the bottom of bumper shock absorber wears out left through-hole to the left slope to the right-hand member of articulated second long frame. The wheel is arranged at the hinge joint of the first long frame and the second long frame, so that when the wheel receives upward vibration force, the vibration is transferred to the first long frame to push the left end of the first hinge to move upwards, the right end of the first hinge presses the shock absorber downwards, the shock-resistant power is resisted by the reset action of the shock absorber, the shock absorption effect is realized, the first long frame is connected with the shock absorber through the first hinge, the first hinge realizes the transmission of the up-down force, even if the first long frame receives other forces such as impact and offset, the shock absorber is not directly acted, the shock absorber is further protected, and the shock absorber is not easy to damage; the right end of the second hinge bracket can freely rotate, so that the connecting parts are few and the second hinge bracket is not easy to damage; the shock absorber can be hidden by the middle tube, a protection effect is achieved on the shock absorber, the shock absorber can be quickly transferred through rotation of the first long frame and the first hinge piece, the reaction time is short, no delay exists, and the stability of the rear wheel is improved by the second long frame.

Further, first long frame and second long frame all are the V-arrangement, and the one end of first long frame indent is the right-hand member, and the one end of second long frame indent is also the right-hand member, is equipped with the connecting axle that passes the wheel center between the left end both sides of first long frame, and the left end both sides below of first long frame is equipped with the extension limit respectively, and the left end both sides of second long frame are connected respectively to two extension limits, and the right-hand member of second long frame indent forms arc part, and arc part laminating frame surface, the bottom of arc part's terminal articulated bumper shock absorber. The use stability is good, and the shock attenuation effect is better.

In summary, the utility model has the following beneficial effects: the shock absorption function can be realized by only one shock absorber, the required components are few, the structure is simple, the shock can be rapidly transmitted to the shock absorber by only the first long frame and the first hinge piece, the reaction time is fast, no delay exists, the shock absorption effect is good, and the structure is firm.
