AI Technical Summary

Problems solved by technology

The hydraulic mechanism of this known bicycle hydraulic disc brake is mostly protruding from the vehicle body, but this method has the problems of large wind resistance, heavy weight and affecting the overall appearance
In addition, although the semi-hydraulic disc brake can be installed in the driver's vertical bar, the installation procedure of this method is complicated and the replacement is difficult
[0005] It can be seen that there is currently a lack of a hydraulic disc brake device for bicycles that can reduce wind resistance, facilitate maintenance, and have a smoother brake line on the market, so the relevant industry is looking for a solution

Abstract

A hydraulic disc brake device includes a cover, a hydraulic unit, an oil tube and a disc brake unit. The cover includes at least one accommodating space, at least one oil route, a proximal end and a distal end. The distal end towards a moving direction of the bicycle. The hydraulic unit includes a hydraulic cylinder and a piston. The hydraulic cylinder is assembled in the accommodating space. The piston is assembled in the hydraulic cylinder for controlling a pressure of the oil route. The disc brake unit is connected with the oil tube and controlled by a pressure of the oil tube.

Description

technical field [0001] The invention relates to a hydraulic brake device for a bicycle, in particular to a hydraulic brake device for a bicycle that can reduce wind resistance, facilitate maintenance, and have smoother brake lines. Background technique [0002] Nowadays, bicycle products have become environmentally friendly products popularized all over the world. Regardless of whether their sports have energy-saving features or urban transportation functions, the bicycle market continues to expand. Under this trend, bicycle hydraulic disc brakes with better braking effect appeared on the market. Compared with traditional mechanical disc brakes, hydraulic disc brakes have more advantages such as stable braking force and high power transmission efficiency. Therefore, bicycle hydraulic disc brakes have gradually become one of the representative accessories of bicycle high-quality vehicles. [0003] At present, there are two types of hydraulic disc brakes for bicycles. The fir...
