Description

Hidden hydraulic brake device

This invention belongs to the technical field of hydraulic brakes. Specifically, it is a concealed hydraulic brake device, which enables the oil pump body and the oil pipe to be hidden inside the handlebar tube. It is not only convenient and quick to install and assemble, but also can effectively reduce foreign matter on the handlebar surface to avoid danger caused by hooking foreign matter while riding.

According to the law, bicycles can not only be used as a means of transportation, but also can be used for sports and leisure. In recent years, people's demand for bicycles with light designs and sophisticated functions has been increasing. With the improvement of manufacturing technology and road conditions, the performance and quality of various bicycles have been continuously improved, and the driving speed has also been increased invisibly. The brake system of the above-mentioned vehicles has gradually developed from the traditional brake system using rubber to brake pads to a disc brake system. At the same time, the braking action of the disc brake system has also developed from the action method of the handle driving the caliper through the pull wire to the action method of using the handle to push the hydraulic oil, so that the hydraulic oil in the oil circuit pushes the brake caliper to achieve the braking effect;

The existing hydraulic brake system is composed of a brake device installed on the handlebar tube and a clamp device installed on the frame, wherein the brake device is provided with an oil pump base connected to the oil pipe on the handlebar tube, and a handle that can be selectively pushed is centrally provided on the oil pump base, and the handle can use a push rod to push a piston installed in the oil pump base, so that the piston acts on the hydraulic oil in the oil pipe to activate the clamp device to produce a braking effect on the wheel. The existing oil pump base in the brake device locked in the handlebar tube includes a piston group, an oil filling group and a handle, so it has a certain volume ratio and many protruding parts, which invisibly occupies a large space of the handlebar. Moreover, although the existing oil pipe can be designed to be routed inside the handlebar tube, when it is connected to the oil pump base, the connecting piece of the oil pipe still needs to pass through the outside of the handlebar tube and connect to the end of the oil pump base. Therefore, the exposed oil pump base and the connecting piece of the oil pipe not only take up space, but also the protruding components not only affect the smoothness of installation, but also easily get hooked on foreign objects during riding, causing danger.

In other words, the brake device installed on the handlebar tube in the existing hydraulic brake system is large in size and exposed, which not only takes up a lot of space and destroys the appearance, but also causes safety concerns in use. Therefore, the existing ones do need to be further improved, which is also the topic that this creation wants to explore.

Due to the above shortcomings and needs, the creator of this invention has studied the above shortcomings and needs with his many years of experience in related technologies and product design and manufacturing, and actively sought solutions. After continuous efforts in research and trial production, he finally successfully developed a hidden hydraulic brake device to overcome the inconvenience and trouble caused by the exposed brake device in the existing hydraulic brake.

Therefore, the main purpose of this invention is to provide a hidden hydraulic brake device, so that the oil pump pipe body and the oil pipe of the brake device can be hidden in the handlebar tube, which is not only convenient and quick to install and assemble, but also improves the overall neatness of use.

In addition, the second main purpose of the present invention is to provide a hidden hydraulic brake device, which has a hidden installation design, can effectively reduce foreign objects on the handlebar surface, avoid danger caused by hooking foreign objects while riding, and improve the overall safety of use.

A pressure handle assembly comprises a handle and a pressure block linked to the handle, wherein the handle is pivotally mounted on the mounting portion of the fixing seat so that the handle can be pivotally displaced between a handle braking position close to the handlebar tube and a handle release position far from the handlebar tube by a rider, and the pressure block is pivotally mounted between the handle and the tie portion of the mounting portion, and a pull portion opposite to the handle and a push portion opposite to the piston rod are formed at two ends of the pivot joint respectively, so that the pressure block can be pivotally displaced between a pressure block braking position opposite to the piston braking position and a pressure block release position opposite to the piston release position after the pressure block is actuated by the handle.

Thus, the hidden hydraulic brake device of the invention can utilize the oil pump tube body to be arranged in the handlebar tube, and the pressure handle assembly can push the piston rod of the oil pump tube body to achieve the braking action by rotating the pressure block through the handle. This is not only convenient and quick to install and assemble, but also allows the oil pump tube body and the oil pipe of the brake device to be hidden in the handlebar tube, which can effectively reduce foreign matter on the handlebar surface and avoid danger caused by hooking foreign matter when riding, greatly improving its practicality and realizing its economic benefits.

Thereby, a concealed hydraulic brake device which is easy to assemble and highly safe is formed.

As for the actual operation of the hidden hydraulic brake device of the present invention, it is as shown in the first, third and fifth figures. In operation, when the rider presses the handle (51) of the pressure handle assembly (50) from the release position of the handle (51) to the brake position of the handle (51) close to the handlebar tube (10), the handle (51) can simultaneously actuate the pressure block (58) through the adjustment block (55), so that the pressure block (58) can push the piston rod (25) of the oil pump body (20) from the piston release position (as shown in the third and fourth figures) to the piston brake position (as shown in the fifth and sixth figures), and the hydraulic oil is transported through the oil pipe (30) to produce a deceleration or braking effect;

When the rider rotates the adjusting bolt (552) on the handle (51) of the pressure handle assembly (50) counterclockwise to press the extension piece (551) of the adjustment block (55), the pressing stroke of the handle (51) in braking operation can be shortened, thereby improving the sensitivity of the brake. In addition, the adjusting block (55) of the pressure handle assembly (50) can be used to actuate the pivot of the pressure block (58) by utilizing the eccentric shaft (56). In conjunction with the design of the eccentric section (560) on the eccentric shaft (56), when the eccentric shaft (56) is rotated to change the position of the lever (581) of the pressure block (58), the braking torque of the handle (51) can be changed, thereby making the braking action more labor-saving and sensitive, and effectively improving the braking effect.

Through the above-mentioned design and description, the present invention's concealed hydraulic brake device utilizes the oil pump tube body (20) to be disposed in the handlebar tube (10), and the pressure handle assembly (50) rotates the pressure block (58) through the handle (51) to push the piston rod (25) of the oil pump tube body (20) to achieve the braking action. This is not only convenient and quick to install and assemble, but also allows the oil pump tube body (20) and the oil pipe (30) of the brake device to be hidden in the handlebar tube (10), which can effectively reduce foreign matter on the handlebar surface, avoid the danger caused by hooking foreign matter when riding, and improve its practicality.
