Description

Bicycle anti-locking structure and bicycle front fork using the same

This creation belongs to the technical field of bicycle front forks, specifically, a bicycle anti-locking structure that can reduce the exposed components of the bicycle to improve the overall riding safety. At the same time, it can effectively save bicycle space and further enhance the aesthetics of the bicycle's appearance design.

According to the data, bicycles are the lightest means of transportation that can provide both leisure and fitness. With the advancement of technology and the improvement of road quality, the speed of bicycles has been continuously increased, which has led manufacturers to pay more attention to the requirements of bicycle brake systems in recent years and continuously improve the functions of the equipment. The current brake system has evolved from the early mechanical drum brake with pads to a hydraulic disc brake system, making the brakes more agile, reliable and effective, and even through the continuous release anti-lock brake mode to avoid the occurrence of brake overheating failure.

However, anti-lock brake units are expensive and are mostly only fixed to the side of the bicycle wheels, making them easily damaged by collisions. In addition, exposed anti-lock brake units will also affect the appearance of the bicycle, making the design lines of the bicycle less smooth.

In other words, the installation design of the existing bicycle anti-locking structure is not perfect, which makes it easy to cause accidental collisions and damage the appearance due to exposure. Therefore, the existing structural design still needs to be improved. This is not only what the industry and users are eager to explore, but also the topic that this creation wants to explore and solve.

In view of the above shortcomings and needs, the creator believes that further corrections are necessary. Therefore, with many years of experience in related technologies and product design and manufacturing, he has conducted research and creation on the above shortcomings and actively sought solutions. After continuous efforts in research and trial production, he finally successfully developed a bicycle anti-lock structure and a bicycle front fork using it, so as to overcome the inconvenience and trouble caused by the existing exposed anti-lock brake unit.

By this means, the bicycle anti-locking structure and the bicycle front fork using it are utilized

The front fork vertical tube of the bicycle front fork has a storage space design, so that the anti-lock brake unit can be set in the storage space without being exposed to the outside, so that the anti-lock brake unit is not easily damaged by collision or outlined by foreign objects, which can effectively ensure the safety of driving, and at the same time, the appearance of the bicycle front fork can be kept intact and have a beautiful appearance. In addition, it can effectively simplify the structure to save parts and increase the flexibility of space use, while not affecting the appearance of the bicycle, which can effectively improve its practicality and further realize its economic benefits.

This invention also utilizes the following technical means to further achieve the aforementioned purposes and effects; for example: preferably, one end of the hydraulic cylinder of the anti-lock brake unit has an oil inlet pipe connector and an electrical signal connector, for the oil inlet pipe and the electrical signal line set to be locked to each other.
