Description

Brake disc protection cover

technical field

The invention relates to a brake disc protection cover.

Background technique

The hydraulic disc brake system of bicycles or locomotives is generally favored by consumers because of its durability, strong braking force and not easy to be affected by weather. If the disc is hit by a foreign object, it will also be damaged and cause the braking function to fail. If the disc collides with the human body during high-speed driving, the disc itself will become a lethal blade that can easily cut through the human tissue, or even break the skin. Bleeding, it will cut tendons and bones and endanger life. Therefore, some people have developed a protective cover to cover the disc, which can not only protect the disc from being damaged by collision, but also prevent the disc from cutting the human body.

However, although the known protective cover overcomes the above-mentioned problems, it still causes the following problems. Since the disc is covered, the heat dissipation function of the disc and the brake caliper group is reduced, which will affect the operation of the brake caliper group. The efficiency of the moving disc increases the danger of riding, and there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive brake disc protection cover to solve the above problems.

Detailed ways

The following examples only illustrate possible embodiments of the present invention, but are not intended to limit the scope of protection of the present invention, and are stated in advance.

Please refer to FIGS. 1 to 5 , which show a preferred embodiment of the present invention. The brake disc protection cover of the present invention includes a casing 1 .

The casing 1 is provided with a notch portion 11, and the notch portion 11 is used to accommodate a brake caliper set 91 of a bicycle (not shown). 2. The other end is provided with an air outlet 22, the air inlet 21 faces the forward direction of the bicycle, and the air outlet 22 faces the notch 11. When the bicycle moves forward, the gas can enter the air guide passage 2 through the air inlet 21, and pass through the outlet 21. The air port 22 blows toward the notch portion 11 , which can effectively reduce the temperature of the brake caliper group 91 accommodated in the notch portion 11 , so as to prevent the braking force of the brake caliper group 91 from decreasing.

In this embodiment, the housing 1 is provided on a fork tube 92 of the bicycle, the brake caliper group 91 is provided on the fork tube 92 and a disc 93 is pivoted on a shaft 94 of the fork tube 92 . The disc 93 is located on the same side of the bicycle, and when viewed along the rotational axis of the disc 93, the housing 1 covers the disc 93 to prevent foreign objects from contacting the disc 93, so the disc 93 protection cover can effectively protect the disc 93 The disk 93 can not only prevent the disk 93 from cutting the human body, but also prevent the disk 93 from being damaged by the collision of foreign objects.

Viewed along the rotational axis of the disc 93 , the housing 1 is in the shape of a three-quarter disk, and the gas guide channel 2 extends a quarter circle along the circumferential direction to guide the gas to the notch 11 .

Preferably, the air guide channel 2 is tapered from the air inlet 21 to the air outlet 22 to increase the flow rate of the air flowing out of the air outlet 22, which can effectively reduce the temperature of the brake caliper group 91. When the bicycle moves forward, the air flows from the air inlet. 21 enters the air guide channel 2 and flows out through the air outlet 22, and blows it to a pad 911 of the brake caliper group 91, so as to avoid the temperature of the pad 911 being too high and affecting the braking force of the clamping disc 93.

Further, the brake disc protection cover also includes a set of connecting parts 3 , and the connecting parts 3 are connected to the end of the casing 1 away from the air guide channel 2 . In this embodiment, the connecting part 3 is integrated with the casing 1 . Forming, the assembly part 3 is sleeved on the fork tube 92. In this embodiment, the assembly part 3 is locked with the half ring 31 so as to be tightly sleeved on the fork tube 92, so as to prevent the shell 1 from being opposite to the fork tube 92 slides.

In this embodiment, the air guide channel 2 is protruded from a side of the casing 1 away from the disk 93 , so that the gas can smoothly enter the air guide channel 2 through the air inlet 21 . The air guide channel 2 includes a guide member 23 . The guide member 23 is a curved semi-circular tube body. The guide member 23 is integrally formed on the side of the housing 1 away from the disc 93 to save manufacturing costs.

It is worth mentioning that, in this embodiment, a concave portion 12 is provided in the center of a side surface of the housing 1 facing the disc 93 , and a baffle 15 is protruded from the periphery of the housing 1 towards the disc 93 to radially shield In the disc 93, an inclined surface section 13 is arranged around the concave portion 12, and the inclined surface section 13 is provided with a plurality of perforations 14, so that the gas can enter the concave section 12 through the plurality of perforations 14 from the side of the casing 1 away from the disc 93, so as to lower the disc. temperature of disk 93. Preferably, the brake disc protection cover includes a wheel fan 4, the wheel fan 4 is pivoted on the shaft 94, and the wheel fan 4 is accommodated in the concave portion 12. When the bicycle is moving at a high speed and the gas located in front of the bicycle flows through the casing. At 1 hour, the gas will drive the wheel fan 4 to rotate, and the wheel fan 4 will move the gas towards the disc 93 , thereby effectively reducing the temperature of the disc 93 to avoid the reduction of the braking force of the brake caliper group 91 .

To sum up, the brake disc protection cover of the present invention can effectively protect the disc, not only to prevent the disc from cutting the human body, but also to prevent the disc from being damaged by the collision of foreign objects. When the bicycle moves forward, the gas can pass through. The air inlet enters the air guide channel, and blows to the notch through the air outlet, which can effectively reduce the temperature of the brake caliper group accommodated in the notch, so as to avoid the decrease of the braking force of the brake caliper group.

The above are the preferred embodiments of the present invention and the technical principles used by them. For those skilled in the art, without departing from the spirit and scope of the present invention, any Obvious changes such as equivalent transformation, simple replacement, etc., all fall within the protection scope of the present invention.
