Description

Bicycle fork

The invention relates to a front fork, in particular to a bicycle front fork.

As the public pays more and more attention to life with equal emphasis on health and entertainment, riding bicycles to achieve sports and leisure purposes is becoming more common. In order to increase the safety of riding, whether it is a high-end bicycle suitable for mountain climbing or racing, or a low-end bicycle for recreational purposes only, all models have an anti-lock brake system.

However, anti-lock brake systems are expensive to build, and are mostly fixed to the wheel of a bicycle and are easily damaged by collision. In addition, the exposed anti-lock brake system will also affect the appearance of the bicycle, making the design lines of the bicycle not smooth enough.

The present invention is to provide a bicycle front fork, so as to prevent the anti-lock brake system from being exposed, thereby preventing the anti-lock brake system from being damaged by collision and affecting the appearance of the bicycle.

A bicycle front fork disclosed in one embodiment of the present invention includes a front fork upper tube, a first fork leg, a second fork leg, and an anti-lock brake mechanism assembly. The first fork leg is disposed at one end of the upper tube of the front fork. The second fork leg is disposed on one end of the front fork provided with the first fork leg. The second fork leg has an accommodation space. The anti-lock brake mechanism assembly is at least partially disposed in the accommodation space of the second fork foot.

According to the anti-lock brake mechanism assembly disclosed in the above embodiment, the anti-lock brake mechanism assembly is at least partially disposed in the accommodation space of the second fork foot and is not exposed to the second fork foot, so that the anti-lock brake is prevented. The brake mechanism assembly is not easy to be damaged by collision, and makes the bicycle fork have a beautiful appearance.

The above description of the content of the new model and the description of the following embodiments are used to demonstrate and explain the principle of the new model, and provide further explanation of the scope of the patent application of the new model.

When the user presses the brake lever, the brake lever generates oil pressure, and this oil pressure is transmitted to the brake caliper 3 through the oil pipe 2 and the hydraulic pressure adjusting cylinder 411, so that the brake caliper 3 is clamped on the wheel of the bicycle (not shown) (Shown) brake discs (not shown) to cause the bicycle to brake.

In this embodiment and some embodiments of the present invention, the main body 41 further includes a first oil pipe assembly 412 and a second oil pipe assembly 413. The first oil pipe assembly 412 is disposed on the oil pressure adjustment cylinder 411 and communicates with the oil outlet passage 4112, and the second oil pipe assembly 413 is disposed on the oil pressure adjustment cylinder 411 and communicates with the oil inlet passage 4111. The oil pipe 2 can be easily assembled in the oil pressure adjusting cylinder 411 through the first oil pipe assembly 412 and the second oil pipe assembly 413, and the parallel oil pipe 2 is not easily bent and can be smoothly connected to the oil outlet channel 4112 and the inlet Oil channel 4111.

Please refer to FIG. 4 and FIG. 5, where FIG. 5 is an exploded perspective view of the main body 41 of FIG. 4. In this embodiment and some embodiments of the present invention, the main body 41 further includes a circuit board 414. The circuit board 414 is disposed between the oil pressure adjusting cylinder 411 and the second oil pipe assembly 413. The circuit board 414 is used to control the operation of the anti-lock brake mechanism assembly 40, and the clamping tightness of the brake caliper 3 can be adjusted to prevent the brake caliper 3 from locking and causing the wheels of the bicycle to slip.

In this embodiment and some embodiments of the present invention, the body member 41 further includes a fixing sleeve 415. The fixing sleeve 415 is disposed between the circuit board 414 and the second oil pipe assembly 413 to fix the position of the circuit board 414.

In this embodiment and some embodiments of the present invention, the main body 41 further includes a waterproof cover 416. The waterproof cover 416 is provided on a side of the oil pressure adjustment cylinder 411 away from the first oil pipe assembly 412 to prevent liquid such as rainwater from flowing into the oil pressure adjustment cylinder 411, thereby preventing the anti-lock brake mechanism assembly 40 from malfunctioning. The waterproof cover 416 abuts the side of the fixing sleeve 415 away from the circuit board 414, so that the waterproof cover 416 can avoid abutting against the circuit board 414 in a large area, thereby avoiding the circuit board 414 being injured due to overextrusion during assembly.
