Folding electric bicycle provided with cushioning rear frame

Abstract

The invention discloses a folding electric bicycle provided with a cushioning rear frame. The folding electric bicycle comprises a folding frame as well as a front wheel, a rear wheel, a seat cushion, a brake system and an electric drive system which are arranged on the folding wheel, wherein the folding frame comprises a middle bearing seat as well as a front frame and the rear frame which are pivotally connected to two sides of the middle bearing seat respectively; the rear frame comprises a battery holder and a rear bottom fork, the common ends of the battery holder and the rear bottom fork are connected with the middle bearing seat through third pivot points, and the tail ends are in gap connection through a cushioning mechanism formed by a locking lever and a damping spring. The folding electric bicycle provided with the cushioning rear frame is elaborate in design and simple in structure, the structure of the rear frame is changed, the cushioning mechanism is arranged on the rear frame, so that kinetic energy formed through bumping and joggling between the rear frame and the middle bearing seat is sufficiently absorbed, and the influence of the bumping on the bicycle structure is reduced; furthermore, a battery can be prevented from being in a bumping state to the greatest extent, accordingly, the influence of the bumping and the joggling on connecting reliability of the battery and a power connection plug is avoided, and the stability of overall operation is greatly improved.

Description

technical field [0001] The invention relates to a foldable electric vehicle, in particular to a foldable electric vehicle with a shock-absorbing rear frame. Background technique [0002] Electric vehicles are more and more accepted by the public because of their convenience, environmental protection and other advantages. The electric vehicle is based on the structure of the existing bicycle and is modified. By adding batteries, drive systems and electronic control systems, the vehicle can be driven by electric energy to run quickly. [0003] Most traditional electric vehicles are bulky and complex in structure, and users feel that they are not very light when using them, especially in complex environments such as going up and down stairs, elevators and subways, etc. The disadvantages of traditional electric vehicles are very obvious, while ordinary bicycles rely on manpower to provide power. It is time-consuming and laborious, and cannot meet the needs of timely and rapid t...

AI Technical Summary

Problems solved by technology

[0006] Due to the strength requirements of electric vehicles, whether it is the center bearing, or the front and rear frames, they often adopt rigid structures, and there is not enough cushioning structure between them, especially between the center bearing and the rear frame. Some electric vehicles have borrowed the cushioning technology of mountain bikes, but this kind of cushioning can only achieve the cushioning of the front and rear wheels, but cannot achieve the cushioning between the rear frame and the middle bearing.

[0007] At the same time, due to the existing electric bicycles, the battery box is basically arranged on the rear frame, and due to the lack of a shock-absorbing structure between the rear frame and the middle bearing seat, when the electric bicycle is running on a bumpy road, it is very easy to Due to the shaking of the electric vehicle, the battery and the power plug are loosened, which affects normal riding
