Abstract

The invention discloses a main frame body of an electric bicycle. The main frame body is characterized by comprising a front fork, a frame main tube assembly, a battery base assembly, a rear swing connecting assembly, a rear fork connecting pipe, a motor wheel installing assembly, a saddle assembly and a rear shock absorption assembly. The front fork is a shock absorption front fork, a triangular structure is basically formed by a rear installing pipe, a rear fork connecting pipe, the motor wheel installing assembly and the shock absorption assembly, and a firm triangular structure is also basically formed by a saddle support, a first supporting tube and a rear installing tube, so that the bearing capacity of the bicycle is greatly improved. The saddle support is directly, rigidly and fixedly connected to a corresponding component of the frame main tube assembly through other corresponding components of the saddle assembly, shock absorption is achieved by using the shock absorption assembly, and the main frame body is firm in structure and remarkable in shock absorption effect.

Description

technical field [0001] The invention relates to a main frame body of an electric bicycle, in particular to a main frame body of an electric bicycle with a shock absorbing function. Background technique [0002] The number of bicycles in our country ranks first in the world, and it has the reputation of "bicycle kingdom". An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with operating components such as a motor, a controller, a battery, a handlebar, and a display instrument system. In recent years, with the continuous improvement of people's living standards, electric bicycles have become more and more popular due to their convenience, comfort, safety, energy saving and environmental protection. According to statistics, the number of electric bicycles in China exceeded 2 by 2013. billion vehicles. [0003] Electric bicycles are generally more suitable for long-...
