Brake no-falling device of electric bicycle

Abstract

The invention relates to a brake antifalling device of an electric bicycle. The brake antifalling device comprises a supporting mechanism, a control device for the supporting mechanism, a locking device and a levelling device; the supporting mechanism comprises two parallelogram mechanisms symmetrically arranged on two sides of a vehicle frame; two front and rear linking frame levers are hinged at the front part and the rear part of the vehicle frame respectively; a hinging point between two ends of the connecting rod and the linking frame lever is hinged with a brace rod downwards; the control device comprises a drive chain wheel controlled by a drive lever, a chain and a driven chain wheel; and a set of a hydraulic spring and a pressure sensor are arranged between the bottom of the brace rod and the connecting rod. In braking, the drive lever drives the drive chain wheel to rotate through a certain device; the parallelogram mechanisms are put down; brake leathers of four brace rods are contacted with ground to realize the aim of braking; and four-point touchdown and hydraulic spring leveling realize the support of the antifalling of the vehicle and people. The brake antifalling device solves the problems that the prior electric bicycle needs to support the ground by feet to keep stable in braking, puts the supporting device down in braking so that the vehicle and people do not fall off and greatly improves stability and safety in braking and shutdown.

Description

Brake non-reversing device for electric bicycles 1. Technical field The invention relates to a braking and supporting device for an electric bicycle, in particular to a device for keeping the vehicle body and people stable and not falling down when temporary braking is required to make the vehicle speed equal to zero when a red light or traffic jam is encountered during driving. 2. Background technology Existing electric bicycles can only achieve balance by putting down the supporting legs when they are parked for a long time so that the car body does not fall down. When the brakes are needed in situations such as red lights or traffic jams, if it is inconvenient to get off the car at this time, it is best to stop before the car. Finally, one foot must be used to support the ground, which is very difficult, especially for women with smaller stature. Moreover, electric bicycles are heavy, and sometimes they will not be stable, causing unsafe factors. In addition, when mov...

Problems solved by technology

Existing electric bicycles can only achieve balance by putting down the supporting legs when they are parked for a long time so that the car body does not fall down. When the brakes are needed in situations such as red lights or traffic jams, if it is inconvenient to get off the car at this time, it is best to stop before the car. Finally, one foot must be used to support the ground, which is very difficult, especially for women with smaller stature

Moreover, electric bicycles are heavy, and sometimes they will not be stable, causing unsafe factors

In addition, when moving forward at a low speed during the starting phase, the car body is also prone to instability and falls to the ground, and it is necessary to use the feet to support it a few times, which also has the above-mentioned problems
