AI Technical Summary

Technical Problem

The existing braking system for electric bicycles cannot achieve simultaneous braking of the front and rear wheels, nor can it guarantee that the braking force of the front and rear wheels will maintain a preset ratio, resulting in safety hazards during emergency braking.

Method used

Design an electric bicycle hydraulic-mechanical hybrid brake control device, which integrates disc brake and drum brake components into a control valve body through a connecting component. Whether the left or right hand is squeezed alone or both hands are squeezed at the same time, the front and rear wheels can be braked simultaneously, and the brake cable is prevented from coming off by a nylon retainer.

Benefits of technology

It ensures that the braking force of the front and rear wheels always maintains a preset ratio, making full use of the adhesion between the front and rear wheels and the ground, improving braking safety and reducing safety hazards.

Abstract

The utility model discloses an electric bicycle mechanical-hydraulic hybrid brake control device which comprises a control valve body, a solid body is arranged on the upper portion of the control valve body, a mounting cavity is formed in the lower portion of the control valve body, a first oil cavity of a connecting assembly is formed in one side of the interior of the solid body, a first piston is arranged in the first oil cavity, and a first piston rod on the lower portion of the first piston extends out of the first oil cavity. The disc brake assembly is arranged on the other side in the entity, the lower portion of a second oil cavity of the disc brake assembly is connected with the lower portion of the first oil cavity through an oil duct, and a second piston rod of the disc brake assembly extends out of the second oil cavity; the brake end of the drum brake assembly is connected with the lower wall of the first piston rod and the lower wall of the second piston rod; the braking device has the advantages that the front and rear wheels can be braked at the same time whether the brake wrench is held by the left and right hands or both hands at the same time, braking force obtained by the front and rear wheels is always kept in a preset proportion, adhesive force between the front and rear wheels of a vehicle and the ground is fully utilized, potential safety hazards of braking are effectively reduced, and braking safety is greatly improved.
