The bicycle is characterized in that in terms of structure: A folding structure, arranged a front triangle zone positioned at a frame, is equipped with four folding shafts which include two folding shafts respectively positioned at an upper end and a lower end of a front tube, a folding dual-tube upper beam and a lower beam, a triangle beam wherein two folding shafts are respectively arranged at an upper end and a lower end, unfolding positioning pin, folding positioning hook, a folding handle comprising a T shape vertical handle tube, a left handle tube, a right handle tube, a positioning pin of handle tube, and a folding foot support comprising a long section of thigh, a connecting box, a spring thruster, a short section of thigh, a folding shaft and a foot support.

Description

Mention the folding expansion equation two-purpose electrically assisted bicycle that puts down

Affiliated technical field

The utility model relate to a kind of can fold to be easy to carry be suitable for the running vehicle that pupil, women, the elderly use most, belong to a kind of of bicycle.

Background technology

Multiple folding bicycle is arranged in the market, electric assisted bicycle, enlarged to the customer and to have chosen the space, its usability and safety all improve a lot, but also there is following obviously weak point, the one, fold or launch complicated operation, time-consuming, effort, incompatibility pupil, women, the elderly use.The 2nd, front-wheel is folding to trailing wheel, has increased width though shortened length.The 3rd, the reduction that has highly but do not shorten length.The 4th, why folding electric bicycle does not have popularization is that storage battery and electrical motor are too heavy because volume is big, not portable after folding.The 5th, because most folding bicycles can not shove along after folding, can only carry or remove, increased physical strength to people, be not easy to carry, lost folding meaning and effect.

Summary of the invention

For overcome the deficiencies in the prior art part the utility model provide make things convenient for pupil, women, physical fitness of old man and ride instead of walk need, folding and expanding is rapid, little can also the pushing away of volume after folding walked, and portablely mentions the folding expansion equation two-purpose electrically assisted bicycle that puts down.

The utility model is to adopt following scheme to realize: mainly be to be provided with foldable structure and to have realized that folding effect and function, its formation comprise folding stand, wheel part, Foldable handlebar, folding pedals, foot-operated drive part, driven by power part, brake portion, bumper, other gauge member etc. at vehicle frame, handlebar and pedal leg.Folding stand comprises: front tube, preceding folding axle, preceding face lower end folding axle, two-tube entablatrance, cross sill, triangle crossbeam, the preceding upward angle of triangle crossbeam folding axle, triangle crossbeam inferior horn folding axle, five-way, five-way elastic axis, rear crotch, bumper, the quick loading electric power driving box support held on the face fold latch hook, launch pilot pin.Vehicle frame entablatrance (two-tube) front end interconnects by front tube upper end folding axle, vehicle frame cross sill front end interconnects by front tube lower end folding axle, entablatrance (two-tube) rear end is gone up angle folding axle before by the triangle crossbeam and is interconnected, the cross sill rear end interconnects by three cantilevered corner beam forward lower comers folding axle, three cantilevered corner beam rear ends and five-way welding are fixing, Li Liang lower end and five-way are fixing by welding, the rear crotch front end interconnects by the five-way elastic axis, the bumper lower end interconnects by elastic axis and rear crotch, the bumper upper end is connected with upright beam by elastic axis, the rear crotch upper end is fixing by welding with quick loading electric power driving box support, the hand-held design Seat stay, Chain stay, back vent mouth and upright beam pipe, five-way is triangular form and interfixes by welding.Triangle crossbeam place is provided with the expansion pilot pin, and cross sill and five-way place are provided with the folding hook of self-orientation.Be provided with quick loading and unloading bracket on rear crotch, the support upper end is provided with bicycle basket location lock.Foldable handlebar is a T font handle riser, left and right folding shaft and the handle pipe knock hole of being provided with of T font handle riser upper lateral tube, handle pipe lower end is provided with folding axle sleeve and locating dowel pin, it is left and right that left and right sides handle pipe is connected T font handle riser upper lateral tube by folding shaft, inserts respectively in the left and right knock hole of T font handle riser upper lateral tube by locating dowel pin.Unload the driven by power case the foot-operated bicycle that drives, unload the driven by power case and then become portable bicycle with bumper.Structure beyond the folded part is respectively with electronic and ordinary bicycle.

The utility model compared with prior art has following advantage:

1, rapid deployment and folding unclamps the expansion pilot pin when folding, holds portable, mentions vertically upward, and folding hook self-orientation is promptly finished folding.During expansion, hold portable, move folding hook, utilize the car body deadweight to put down gently vertically downward promptly and launch automatically, remove tight pilot pin fast and can ride usefulness, only needed for three seconds.

2, its function and existing electric assisted bicycle are basic identical, and available manpower is available power again, but also manpower electric power drives simultaneously.Can be as required, unloading the driven by power case is exactly bicycle,

3, easy to carry, be suitable for that the city people are on and off duty, the student goes to school and ride usefulness, be vertical square after folding, front and back two-wheeled word order, two-wheeled land and can carry out, solved the electric assisted bicycle volume greatly, too heavy, not portative problem.
