Abstract

The utility model relates to a shock damping structure of a bicycle. Elastic bodies are arranged on the members such as a frame, a front fork, a grip, and the like. When the bicycle generating shock beacuse of passing through a bumpy road, the elastic bodies arranged on the members can be utilized to play the role of shock damping, thereby improving the riding comfort and the ground-attaching performance of the bicycle.

Description

Shockproof structure of bicycle

[technical field]

The utility model is about a kind of Shockproof structure of bicycle, is particularly driving bicycle when jolting the road surface about a kind of, can produce shock-absorbing function to acquire traveling comfort and to paste the Shockproof structure of bicycle of ground property.

[background technology]

Bicycle not only can be used as the instrument of riding instead of walk, have the effect of sport and body-building again concurrently, especially in the surging epoch of the energy, except the raising public transportation is taken, bicycle is the short distance walking-replacing tool an of the best especially, therefore bikeway all can actively be planned in each big city, to encourage the resident to drive bicycle, please cooperate Fig. 1 to consult, the basic framework of bicycle 1 is that the front end at vehicle frame 11 is equipped with handgrip 12 and front fork 13, this front fork 13 is arranged in the wheel shaft (flower-drum) of front-wheel 14 and locates, and vehicle frame 11 rear sides then collude on the wheel shaft (flower-drum) that pawl is sheathed on trailing wheel 15 with it, and establish with cushion 16 upper end in the middle of the vehicle frame 11, what downside then was equipped with pedal tramples member 17, thereby can after step on pedal, utilize sprocket wheel 18 to drive trailing wheel 15 and promote front-wheel 14 and rotate, to reach the purpose that makes bicycle 1 advance.Field at bicycle, for overcome rugged road surface with allow drive bicycle 1 can be comparatively comfortable when advancing, therefore all can be provided with shock-absorbing member 19 at front-wheel 14 places basically, setting by these front-wheel 14 place's shock-absorbing members 19, can be when jolting the road surface, the shaking force that produces can be reduced, cause the person's of riding discomfort to reduce shaking force, but shock-absorbing member 19 is set because of only having at front fork 13, and the shaking force that road bump produces can be via front-wheel 14, trailing wheel 15 and vehicle frame 11 upwards conduct to each position, so that at vehicle frame 11, trailing wheel 15 and handgrip 12 places all can experience shaking force, cause the both hands that are gripped on handgrip 12 and be sitting in buttocks on the cushion 16 and can conduct, and can allow this two position of the person of riding feel ill, and because of the single shock-absorbing in the place ahead only, when bicycle jolts the road surface in the fast running process, make the subsides ground property reduction of whole bicycle because of the spring of trailing wheel 15, forfeiture trailing wheel 15 due and ground-surface friction force, make takeoff output and deceleration and stopping performance influenced, the essentiality that is improved is arranged in fact.

[utility model content]

A purpose is to provide a kind of Shockproof structure of bicycle first of the utility model, borrow in vehicle frame/in be provided with elastic body, and can produce a damping effectiveness, drive the traveling comfort of bicycle and paste the ground property with raising.

A purpose again of the utility model is to provide a kind of Shockproof structure of bicycle, borrow in front fork/in be provided with elastic body, and can produce a damping effectiveness, drive the traveling comfort of bicycle and paste the ground property with raising.

The another purpose of the utility model is to provide a kind of Shockproof structure of bicycle, borrow in handgrip/in be provided with elastic body, and can produce a damping effectiveness, drive the traveling comfort of bicycle and paste the ground property with raising.

Aforesaid Shockproof structure of bicycle, mainly be that parts places such as vehicle frame, handgrip and front fork at bicycle are provided with elastic body, by this elastomeric setting up, can be when producing shaking force by the road surface of jolting at bicycle, utilize elastic body to absorb to conduct to the shaking force at vehicle frame, handgrip or front fork place, and shaking force is dropped to minimum, the traveling comfort that drives with raising and paste the ground property.

[specific embodiment]

Effect for enabling to be easier to understand structure of the present utility model and can reach cooperates graphic being described as follows now.

The utility model mainly is to utilize to establish with elastic body at each parts place of bicycle, so as to absorbing vibration power, at first see also shown in Figure 2, be that the utility model is provided with elastic body 3 at vehicle frame 2 places, this elastic body 3 is provided in a side of the middle pipe 21 of vehicle frame 2 and two limits pipe, the 22 middle places at rear, because existing bicycle generally has been provided with the shock-absorbing member all at the front-wheel place, and can reduce the shaking force in the place ahead, then the utility model is increased in vehicle frame 2 places and establishes with elastic body 3, the middle pipe 21 of vehicle frame 2 and the limit of rear side especially are set manage 22 places, then the shaking force at rear is after conducting to vehicle frame 2, just can utilize elastic body 3 to be absorbed, certainly also can be located on the implementation on the limit pipe 23 in the place ahead, and can effectively reduce shaking force, and allow the person's of riding buttocks can not experience the shaking force that vehicle frame 2 is passed to cushion, can improve the traveling comfort that drives, and because of being before this simultaneously by the elastic body 3 at the shock-absorbing member of front fork and vehicle frame 2 places, the mode of the common absorbing vibration power in rear also can improve the subsides ground property of bicycle.

See also Fig. 3 again, for the utility model is provided with at handgrip 4 places with elastic body 3, its two sides that can be arranged on handgrip 4 are near handle 41 places, and can utilize setting up of elastic body 3, when consequently producing shaking force by the road surface of jolting, the shaking force that is passed to handgrip 4 can be absorbed to make by elastic body 3 to be dropped to minimumly, and the both hands that then are gripped on handgrip 4 places just can be avoided the numb situation of palm, thereby improve the traveling comfort that drives.

See also Fig. 4 again, for the utility model is provided with elastic body 3 at front fork 5 places, it is arranged on the lower beam 51 middle places of front fork 5, though existing partially self car is provided with the shock-absorbing member at front-wheel, but the utility model is in addition reinforcement of front fork 5 places that do not have this shock-absorbing member, and shaking force is dropped to minimum, the traveling comfort that drives with raising and paste the ground property.

In sum, structure of the present utility model does not see the market, and really can reach the purpose of demand.
