Brake cable for folding bicycle

Abstract

The invention relates to a brake cable for a folding bicycle. The brake cable comprises an inner tube (1), a tubular layer (2), a first protective layer (3), a reinforcing layer (4), a second protective layer (5) and a surface protective layer (6), wherein the inner tube (1) is like a spring curve in the length direction; a steel wire is arranged inside the inner tube (1); an annular belt (7) is arranged at the end part of the steel wire. As for the brake cable for the folding bicycle disclosed by the invention, the outer layer of the brake cable is low in possibility of scrape or damage by an external force, so that the steel wire in the inner tube cannot be popped up, and the driving safety can be ensured; the brake cable can be automatically retracted to bring convenience for folding the bicycle; the annular belt at the end part of the steel wire is used for fixing the steel wire with a handle, so that the steel wire cannot be detached from the handle, and the driving safety can be ensured.

Description

technical field [0001] The invention relates to a brake cable for a folding bicycle brake system. The utility model belongs to the technical field of vehicle accessories. Background technique [0002] The folding car has the advantages of being foldable, easy to control, and easy to carry. During the folding process, no external tools are needed. The car can be folded or unfolded manually. After folding, it can be stored in the trunk of the car more conveniently. Or in the boarding box, the brake system of the vehicle includes brake handles, brake lines, brake calipers and other accessories. [0003] After the existing folding bicycle is folded, the brake line cannot be folded, and its length does not change, and a longer section is bent outside. It is easy to be hooked by external objects during the transportation of the vehicle, which affects the folding function of the vehicle; the existing vehicle brake The system only pays attention to the protection of longitudinal t...

AI Technical Summary

Problems solved by technology

[0003] After the existing folding bicycle is folded, the brake line cannot be folded, and its length does not change, and a longer section is bent outside. It is easy to be hooked by external objects during the transportation of the vehicle, which affects the folding function of the vehicle; the existing vehicle brake The system only pays attention to the protection of longitudinal tensile stress and compressive stress. The outer layer of the brake line is easily scratched or damaged by external force, which will cause the steel wire in the inner tube to pop out, and the brake system will fail, which will affect driving safety; The end of the steel wire is a hook used to fix the handle. After a long time of use, the hook will be deformed, which will cause the steel wire to be disengaged from the handle, resulting in brake failure and accidents.
