Disc cover

This creation is related to the protective cover, especially regarding a disc cover.

According to recent years, bicycles are popular, and more and more people are engaged in cycling. This has led to huge business opportunities in the bicycle industry, including one in the field of brakes. The hydraulic disc brake system is durable, has strong braking force and is not susceptible to weather. The characteristics are generally favored by consumers.

However, when the bicycle is traveling too fast and unfortunately collides or crashes, the disc may be damaged if it is hit by foreign objects, causing the brake function to malfunction, and if the disc hits the human body at high speed, the disc itself will It will become a blade with lethality and can easily open the human tissue. It will break the skin and bleed, but it will endanger the danger of life and there are defects that need to be improved.

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

The main purpose of the present invention is to provide a disc cover that can effectively shield the disc, not only to protect the disc from being damaged by collision, but also to prevent the disc from cutting the human body.

In order to achieve the above object, the present invention provides a disc protection cover which is provided on a fork tube of a bicycle, the fork tube is provided with a shaft hole, the opening direction of the shaft hole defines an axial direction, and the bicycle is further provided with a shaft. a disc drive disc, the disc protection cover includes a casing for the shaft to be pierced and the shaft rod is further disposed on the shaft hole of the fork pipe, and the casing and the brake disc are viewed along the axial direction It is located on the same side of the bicycle and the housing shields the brake disc.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to FIG. 1 to FIG. 4, a preferred embodiment of the present invention is shown. The disc protection cover of the present invention is provided on a fork (91) of a bicycle (not shown), and the fork tube 91 is provided with a shaft hole. In 911, the opening direction of the shaft hole 911 defines an axial direction, and the bicycle is further provided with a brake disc 92, and the disc protection cover includes a casing 1.

The housing 1 is provided with a shaft 93 and the shaft 93 is further disposed in the shaft hole 911 of the fork tube 91. The shaft 93 is additionally disposed on the tire of the bicycle (not shown) along the axial direction. The housing 1 and the brake disc 92 are located on the same side of the bicycle and the housing 1 shields the brake disc 92 to prevent foreign objects from contacting the brake disc 92, so the disc is protected. The cover can effectively protect the brake disc 92, which not only prevents the brake disc 92 from cutting the human body, but also prevents the disc from being damaged by the collision of foreign objects. Further, in the embodiment, the housing 1 is laterally disposed with a retaining edge 18 extending axially toward the brake disc 92 and radially shielding the brake disc 92. It is possible to more effectively prevent the foreign object from contacting the brake disc 92 via the radial direction.

Specifically, the housing 1 is formed in a three-quarter disc shape, and the housing 1 is provided with a notch portion 11 for receiving a bicycle caliper set of the bicycle. 94. The brake caliper set 94 is for braking the brake disc 92.

Preferably, the housing 1 is provided with a plurality of annular perforations 12 in an annular arrangement to increase air convection around the brake disc 92 to improve heat dissipation efficiency. Further, the housing 1 includes a first surface 131 and a second surface 132. The first surface 131 faces the brake disk 92. The center of the first surface 131 is provided with a recess 14 and a recess. The peripheral ring of the 14 is provided with a beveled section 15 , and a peripheral section 16 is disposed on the outer circumference of the inclined section 15 . The perforations 12 are disposed through the inclined section 15 for the air to flow into the recess through the axial and radial directions simultaneously. 14.

It is to be noted that in the embodiment, the plane segment 16 is provided with a plurality of convex portions 17 in the axial direction of the second surface 132. The convex portions 17 are triangular along the axial direction, and the convex portions are respectively arranged. 17 and radially opening a hole 171, when the bicycle is advanced, the radial direction of the casing 1 is in a windward state, and air can flow into the casing 1 through the opening 171 of each convex portion 17 The air convection around the brake disk 92 shielded by the casing 1 is increased to lower the temperature of the brake disk 92, so that the heat dissipation efficiency of the brake disk 92 is improved.

In summary, the disc protection cover of the present invention, the housing and the brake disc are on the same side of the bicycle and the housing shields the brake disc to prevent foreign objects from contacting the brake disc, so The disc protection cover can effectively protect the brake disc, not only avoiding the brake disc from cutting the human body, but also preventing the disc from being damaged by the collision of foreign objects.

In addition, a rim is disposed on the outer circumference of the housing, and the rib extends axially toward the brake disc and radially shields the brake disc, thereby more effectively preventing contact of the foreign object through the radial direction. Go to the brake disc.
