Abstract

The utility model relates to a folding electric bicycle, which belongs to the electric bicycle class. The utility model is characterized in that pipe components of a bicycle frame is fixedly connected by rotating shafts; a back support is composed of a support of an upper section and a support of a lower section which are connected by a rotating shaft; the support of an upper section is provided with a U-shaped groove; the support of a lower section is in an elliptic cylinder shape and can be clamped into the groove of the support of an upper section; elastic buckle devices are arranged inside the support of a lower section; a base seat of a battery box of the utility model is fixed on a main body pipe of the bicycle frame; the base seat of the battery box is an arc-shaped cushion block; the battery box is inserted in the base seat in an opening type. The folding electric bicycle has a small volume after folded, and the utility model has the advantages of style, portability, convenience and fashion. The folding electric bicycle can be conveniently put into a car to make long distance travel realized.

Description

A kind of folding electric bicycle

Technical field

The utility model belongs to the Electrical Bicycle class.

Background technology

Change along with lifestyle, the reinforcement of environmental protection consciousness, battery-driven car becomes the vehicle that people like day by day, and especially when going out tourism and leisure, Electrical Bicycle is because light and handy, environmental protection, characteristics easily, people's first-selection especially, but because the Electrical Bicycle volume is still bigger, camp, deposit during outing convenient inadequately, especially when travelling at a distance owing to power is limited, inconvenience is carried again, can not satisfy the demand of leisure fashion.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provide a kind of volume little, in light weight, open and easy, the portable folding electric bicycle of folding.

The technical solution of the utility model is as follows:

A kind of folding electric bicycle, mainly constitute by wheel, bicycle frame pipe, saddle, battery case, lamp box, wherein bicycle frame pipe comprises front fork, head pipe, handgrip standpipe, handgrip, main body pipe, middle pipe, goes up pipe, back support, it is characterized in that: between bicycle frame pipe by the rotating shaft captive joint, and the back is supported by epimere support and hypomere support and is constituted, and two sections support and connected by a rotating shaft.

The utility model epimere is supported with groove, and hypomere supports in the groove that can snap in the epimere support, and hypomere has an elasticity buckle device in supporting, and when folding or be deployed into the position that needs, hypomere supports interior elasticity buckle device and ejects automatically, fixes car.

The pedestal of battery case of the present utility model is fixed on the main body of vehicle frame pipe, is a circular arc cushion block, and battery case is open to be inserted on the pedestal, and circular arc allows angle inside to place and to take, and is simple and convenient.

Car of the present utility model, battery can promptly fold and decompose, and volume after folding is little, and is easy to carry, can be placed on easily in car or other car, realizes the tourism and leisure fashion of farther distance, flexible.

The specific embodiment

As Fig. 1,2,3, shown in 4, a kind of folding electric bicycle, by wheel 1, bicycle frame pipe 2, saddle 3, battery case 4, lamp box 5 constitutes, wherein bicycle frame pipe 2 comprises front fork, the head pipe, the handgrip standpipe, handgrip, the main body pipe, middle pipe, last pipe, the back is supported, it is characterized in that: 2 of bicycle frame pipes are by rotating shaft 6 captive joints, and the back is supported by epimere support 21 and hypomere support 22 and is constituted, two sections support and are connected by a rotating shaft, epimere supports 21 U-lag, it is cylindroid that hypomere supports 22, hypomere supports 22 and can snap in the groove of epimere support 21, hypomere supports flexible buckle device in 22, rotating shaft is to a lateral movement during back supported folding, in folding or expansion process, when folding or when being deployed into the position that needs, elasticity buckle device in hypomere supports ejects automatically, fix car, make folding or launch after can use at once, need not fixing in addition.

The pedestal of battery case 4 of the present utility model is fixed on the main body of vehicle frame pipe, and the pedestal of battery case is a circular-arc cushion block, is easy to the battery contraposition and fixes; Battery case is open to be inserted on the pedestal, and all can place and take in the circular arc permission angle, flexible, places back battery case concentric in pedestal allows angle in addition and moves, and contact is good.
