Electric bicycle

Abstract

The invention relates to an electric bicycle, which comprises a bicycle frame forwards and backwards extending in the bicycle body direction, wherein the bicycle frame comprises a front fork, a steering post, a steering handle, a head pipe, a main pipe, a battery bracket, a pedal pipe, a fork frame pipe, a back flat fork, a back shock absorber, a seat cushion support pipe, left and right tail frame support pipes, a tail frame and a foot supporter, the front fork is arranged at the front end part of the bicycle frame, the steering post and the steering handle are arranged above the front fork, the head pipe is sheathed on the steering post, the top end of the main pipe is engaged with the back surface of the head pipe, the battery bracket is distributed at the two sides of the main pipe, the pedal pipe is arranged at the front end of the horizontal section of the main pipe, the fork frame plate is fixedly connected with the tail end of the main pipe, the tail end of the back flat fork is connected onto a back axle, the front end of the back flat fork is connected onto the fork frame plate, the back shock absorber is arranged between the back flat fork and the main pipe, the seat cushion support pipe is erected above the main pipe, the left and right tail frame support pipes extend towards the back upper side above the fork frame plate, the two sides of the tail frame are connected with the left and right tail frame support pipes, the front end of the tail frame is connected with the seat cushion support pipe, and the foot supporter is arranged under the fork frame plate. The electric bicycle has the advantages that the single main pipe and the middle single shock absorber are adopted as back shock absorption parts, the number of components is reduced, the structure of the whole bicycle body is compact, the weight is light, and the freedom of other structural design is ensured.

Description

technical field [0001] The invention relates to a land trackless transportation vehicle, in particular to a two-wheeled electric vehicle. Background technique [0002] Two-wheeled electric vehicles are popular among users because of their environmental protection and portability. Consumers want electric vehicles to have a good driving experience, and at the same time require their structures to be lightweight. The frame of an electric vehicle is the most critical factor affecting the structure. The utility model patent with the publication number CN202147792U discloses an electric vehicle frame, which consists of a main frame horizontal tube, a tube head, a tube middle, a tube tail, and a battery storage box. , frame main frame pipe vertical pipe, fixed beam, tail beam, support pipe, liner pipe, fixed iron sheet, etc. The main horizontal pipe of the frame is divided into symmetrical pipe head, pipe middle, pipe tail and other parts. After the side welding, it forms a circu...

AI Technical Summary

Problems solved by technology

This structure adopts a ring-shaped main pipe, and there are main pipes on the left and right sides of the car body. The structure is relatively complicated, which increases the weight of the car body and limits the freedom of other structural designs.
