Abstract

The invention discloses a novel variable-speed folding bicycle. The novel variable-speed folding bicycle can be folded from a central tube of a frame; a chain between a front wheel chain wheel and a rear wheel chain wheel can be tightened or loosened through regulating angles of two small chain wheels of a derailleur of a rear wheel bearing so as to prevent the chain from loosening and falling after folding the bicycle.

Description

A kind of speed-changeable folding bicycle
One, technical field: the present invention relates to a kind of speed-changeable folding bicycle, relate in particular in vehicle frame and manage folding bicycle, be equally applicable to manage in vehicle frame folding Electrical Bicycle.
Two, background technology:
Bicycle is of a great variety in the market, has imported car, domestic car, and price is etc. not various in style.Mainly there are 2 kinds of folding modes in folding bicycle, a kind of is that pipe is folding in vehicle frame, and another kind is folding at down tube, and these two kinds of modes all have use in different occasions.And speed-changeable folding bicycle generally adopts down tube folding mode, which distance between front sprocket wheel and rear change wheels in folding process can not change, and chain can be from not dropping from gear yet.And in employing vehicle frame, manage the variable speed bicycle of folding mode, and the distance in folding process between front sprocket wheel and rear change wheels will constantly diminish, and chain length is relatively long, can drop from gear.
Three, summary of the invention:
1, goal of the invention: the invention provides a kind of speed-changeable folding bicycle, this Electrical Bicycle has been realized pipe in vehicle frame and folded, and chain can not come off from gear in folding process.
2, technical scheme:
Speed-changeable folding bicycle, comprises front sprocket wheel, and rear gear shift flywheel group is dialled chain device, and chain, manages in vehicle frame, folding rotary shaft.Folding rotary shaft is arranged in vehicle frame and manages trigonum, rear, bottom, back fork of bicycle body is folding forward by folding rotary shaft, after in folding process, speed varying chain wheels are gradually near front sprocket wheel, the centre distance of rear gear shift flywheel group and front sprocket wheel diminishes, chain on gear is relatively elongated, by group chain device underarm, rotate to prop up chain it is expanded outward, chain is fastened on gear always.
3, advantage and effect: the invention provides a kind of speed-changeable folding bicycle, solved the variable speed bicycle problem that chain drops in folding process of managing folding mode in vehicle frame, folding convenient.
Four, accompanying drawing explanation
Fig. 1 speed-changeable folding bicycle structure
Structure after Fig. 2 speed-changeable folding bicycle is folding
Five, the specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Folding electric speed-variating bicycle, comprises and in vehicle frame, manages 1, down tube 2, front sprocket wheel 3, rear gear shift flywheel group 5, chain 4, dial chain device 6, back vent body 7 and dial chain device underarm 8.Bicycle battery is positioned in down tube, folding rotary shaft 21 is arranged in the trigonum that vehicle frame is managed rear, bottom, back vent body is connected by folding rotary shaft with pipe in vehicle frame, when folding, back vent body rotates forward by folding rotary shaft, and near front-wheel, also sprocket wheel is close forward gradually for rear gear shift flywheel group gradually, distance between the two diminishes, dial chain device and outwards rotate underarm, chain is outwards propped up, guarantee can not come off because of long at the folding rear chain of car.
Above-described embodiment is just to allow one of ordinary skilled in the art can understand content of the present invention and implement according to this for technical conceive of the present invention and feature being described, its objective is, can not limit the scope of the invention with this.Without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.

Claims (5)

1. a speed-changeable folding bicycle, is characterized in that, bicycle pipe place in vehicle frame is folding, and the chain device control chain degree of tightness of dialling of using by speed change realizes the folding of speed-changeable folding bicycle.
2. speed-changeable folding bicycle according to claim 1, is characterized in that, the folding rotary shaft of bicycle is arranged in the trigonum that vehicle frame is managed rear, bottom, and back fork of bicycle body rotates forward to realize by this folding rotary shaft and folds.
3. speed-changeable folding bicycle according to claim 1, is characterized in that, bicycle front wheel and rear gear shift flywheel lay respectively at the both sides of folding rotary shaft, and when bicycle is folding, the width between centers of front sprocket wheel and rear gear shift flywheel can change.
4. speed-changeable folding bicycle according to claim 1, is characterized in that, dials chain device underarm and outwards rotates with tensioning chain when bicycle is folding forward, and chain is expanded outward, guarantees that chain does not come off from gear.
5. according to right 1, require described speed-changeable folding bicycle, it is characterized in that, by speed change, use the length of group chain device underarm to adjust the degree of tightness of chain, before increase when sprocket wheel quantity, the number of teeth and rear gear shift flywheel quantity, the number of teeth, adjustment is dialled chain device length and is rotated group chain device underarm and makes chain fold front and back always in tensioning state, guarantees that chain does not come off from gear.
