A central cable-stayed shock-absorbing structure of an electric bicycle

Abstract

An intermediate oblique-pulling damping structure of an electric bicycle comprises a bicycle frame, a rear rocker and a spring damper. The bicycle frame comprises a front longitudinal beam, a middle cross beam, a left cross beam, a right cross beam and a rear rocker connecting rod. The rear rocker comprises a right rear rocker body and a left rear rocker body, and the right rear rocker body and the left rear rocker body are arranged in a V shape. A bicycle frame connecting part and a damper connecting part are arranged on a top end plane of the front end of the rear rocker, and the rear end of the rear rocker is provided with pivot combining parts used for being connected with a rear wheel. The rear rocker connecting rod of the bicycle frame penetrates through the bicycle frame connecting part of the rear rocker, so that the rear rocker is connected between the left cross beam and the right cross beam of the bicycle frame in a pivoted mode. One end of the spring damper is connected to the middle cross beam of the bicycle frame in a pivoted mode, and the other end of the spring damper obliquely faces upwards to be connected to the damper connecting part of the rear rocker in a pivoted mode. The bicycle frame, the spring damper and the rear rocker are connected in the pivoted mode, and the bicycle frame has a good stable supporting effect.

Description

technical field [0001] The invention relates to a shock absorbing structure of an electric bicycle, in particular to a center cable-stayed shock absorbing structure of an electric bicycle. Background technique [0002] At present, people are using more and more electric bicycles in short-distance traffic. Compared with automobiles, electric bicycles are energy-saving, convenient, and non-congested. Compared with bicycles, they have speed advantages and save time and effort. transportation. As a result, people have put forward higher requirements for the safety and comfort of electric bicycles. The design of electric bicycle in the prior art is mainly to refer to, carry out in conjunction with the structure of bicycle and motorcycle, what have directly is to install power unit additional on the structural frame of bicycle, or is refitted as electric drive under the structural frame of motorcycle. [0003] The design of the shock absorption system of an electric bicycle play...

AI Technical Summary

Problems solved by technology

[0003] The design of the shock absorption system of an electric bicycle plays an important role in maintaining good dynamic performance of the vehicle. The suspension system of an existing electric bicycle generally refers to the design of a motorcycle, including a rear rocker connected to the frame and two separate The spring shock absorber installed on both sides of the rear wheel, the rear shock absorber of the existing electric bicycle is mostly simple bilateral micro-angle shock absorption, the result is that the shock absorption effect is not good, and the driving experience when turning is relatively poor. stiff

However, the weight and speed of ordinary electric bicycles are much lower than those of motorcycles. Therefore, the design of the shock absorption system of electric bicycles cannot completely refer to the structure of bicycles and motorcycles. It needs to be designed according to the characteristics of electric bicycles to obtain reasonable design and weight. Lightweight, shock-absorbing structure with good shock-absorbing effect
