Abstract

The utility model discloses a folding and damping bicycle. The lower end of a vertical pipe extends into a vertical sleeve of a cross sleeve, and a horizontal sleeve of the cross sleeve is hinged with a horizontal fork. The upper part of the vertical pipe is provided with a clamp ring, and a vibration damper pilot sheathed with a spring and a slide seat is hinged between an upper pipe and the clamp ring. A vertical fork is hinged with the slide seat. The utility model has the advantages of simple structure, convenient fold and obvious damping effect. The utility model is particularly suitable for the bicycle which is additionally provided with a boosting device and is convenient to transport and store.

Description

A kind of folding shockproof bicycle

The utility model relate to a kind of can fold can damping bicycle.

Traditional bicycle can not fold, and damping requires also not high, and general reaches the damping purpose by the spring under the cushion.And at present a lot of bicycles can repack mini-motorcycle into by the whole bag of tricks, such bicycle only comes damping just can not reach requirement by the spring under the cushion, if adopt the two upright V shape rear wheel shock-absorbing of similar motor bike system to seem too complicated again concerning bicycle, wasted very much.

The purpose of this utility model just is to provide a kind of damping effect rational in infrastructure good and can folding of bicycle or the bicycle of band assisting device.

The purpose of this utility model is achieved in that it comprises cross cover, clamp ring, slide, spring, vibration damper pilot, and other bicycle assembly parts, the integral body that triangle is maintained fixed before the vehicle frame that pipe, following pipe, standpipe constitute on the bicycle, concrete structure is that cross is enclosed within the standpipe lower end, standpipe stretches into the upright sleeve of cross cover, uses bolt, unclamps the bolt standpipe and can rotate in upright sleeve, horizontal bush and chain stay link, and chain stay can be done longitudinal oscillation by preceding relatively spider.Clamp ring is enclosed within outside the standpipe upper end, use bolt, unclamping bolt can rotate or up-and-down movement around standpipe, hinge joint of clamp ring and vibration damper pilot, vibration damper pilot other end and the hinge joint of last pipe, be with spring on the vibration damper pilot, the spring of close clamp ring is connected with the slide on being enclosed within vibration damper pilot, upright fork and slide hinge joint.Triangle peace is pitched, is stood to pitch and link up actively before making vehicle frame like this, when cycle wheel is subjected to road shocks, and the upper and lower swing of chain stay, the slide by on the upright fork promotion vibration damper pilot make spring generation deformation, thereby consumed energy plays buffer action.Separately the hinge joint mechanism of vibration damper pilot and last pipe makes it to separate with preceding triangle, and preceding like this spider just can rotate in clamp ring and the upright sleeve of cross cover around standpipe, can realize with the standpipe being the vehicle frame folding at center.

In order further to improve said structure, cross cover and standpipe and chain stay can adopt such connection mode: the standpipe lower end has the upright sleeve that a threaded shaft extension is gone into the cross cover, on the vehicle frame central siphon, be provided with the supporting vertical plate that two symmetries have the hole, chain stay captive joint central siphon, the supporting vertical plate on cross cover horizontal bush and the central siphon was through at symmetrical holes with bolt and was hinged together.Forked element is arranged behind the slide, and the forked element sidewall links clamp ring with bolt, porosely on the forked element roof allows the bumper conduit pass and locks end socket with nut.Being connected between vibration damper pilot and the last pipe: on manage fixedly ball cap, the termination of vibration damper pilot is installed a bulb and can be inserted in the ball cap, have nut that spring is located behind the bulb, vibration damper pilot and last pipe not only are connected and actively also can separate easily at any time like this, are convenient to fold.

The utility model is applicable to the rear wheel shock-absorbing of various bicycles, mini-motorcycle, because the bumper locus is big, available spring also can be bigger, so antidetonation, shock resistance improve, in addition, two parts grade separation combination before and after the vehicle frame, the junction is active, the good stability of vehicle frame, and can be easily the vehicle frame folding of bicycle be got up, make the front and back wheel that is contained on the vehicle frame and together, shorten the length of bicycle, be convenient to transportation, deposit and maintain.In addition, the utility model shock absorption device is simple, and newly-increased parts are few, and overall weight is lighter relatively, and original vehicle frame is changed seldom, is convenient to promote and produces.

By the following examples and accompanying drawing the utility model is described further.

Fig. 1 is the vehicle frame scheme drawing of an embodiment.Among Fig. 1, standpipe 1, on manage 2, following pipe 3 is welded into triangle before the stable vehicle frame, upright fork 4 and chain stay 5 use bolted splice, the other end of chain stay 5 is connected by central siphon 7 and cross cover 6, cross overlaps 6 belows that are installed in standpipe 1.The top of standpipe 1 is with clamp ring 8, and the other end of upright fork 4 also links on slide 9, is with spring 10 on the vibration damper pilot 11, and there is the slide 9 that is enclosed within on the guide rod 11 10 1 back of spring.

Fig. 2 is the chain stay of present embodiment and the structural representation between cross cover and the standpipe, and Fig. 3 is Fig. 2 birds-eye view.In Fig. 2 and Fig. 3, one section threaded axle 13 is inserted in the lower end of standpipe 1, and the upright sleeve 14 of cross cover 6 is enclosed within on the axle 13.Axle 13 and upright sleeve 14 usefulness nuts 15 and tightly or unclamp.Chain stay 5 is welded on the central siphon 7, and central siphon 7 has two symmetries to have the supporting vertical plate 18 in hole, passes the horizontal bush 16 of cross cover 6 and the hole of supporting vertical plate 18 with bolt 17, and the two is linked.

Fig. 4 is the structural representation of shock absorber system.Last pipe 2 front ends are being fixed ball cap 12, be with spring on the vibration damper pilot 11, guide rod one end termination is a bulb 20, on the guide rod after the bulb 20 nut 19 is arranged, bulb 20 inserts in the ball cap 12, available nut 19 is back spring 10 location, ins succession and be enclosed within slide 9 on the guide rod 11 in spring 10 other ends.21 hinge joints of upright fork 4 usefulness bolts are on slide 9.The other end of guide rod 11 is by forked element 24 and clamp ring 8 bonded assemblys.Lock bolt device 22 can firmly be fixed on clamp ring 8 on the standpipe 1.

Fig. 5 is clamp ring and guide rod 11 and clamp ring 9 bonded assembly partial top view, and clamp ring 8 puts on the two side of forked element 24, by bolt and forked element 24 hinge joints, a glance is arranged on forked element 24 roofs, can allow guide rod 11 put in, and lock end sockets with nut 23.Forked element 24 roofs are close to the slide 9 of the upright fork 4 of hinge joint outward.

In the present embodiment with after the locking of the bolt nut of various point of connection, monolithic stability, and can pass through spring 10 effective dampings, and after each point of connection unclamped, just the preceding trigonometric sum Vee formation vehicle frame folding of bicycle can being got up.
