The following describes a mudguard proposed according to an embodiment of the present disclosure with reference to FIGS. 1 to 4, including: a mudguard body 11 and a brake portion 12, the mudguard body 11 is adapted to be opposed to the outer peripheral surface of the wheel 50, and the mudguard One end of the plate body 11 is formed as a pivotal end and the other end is formed as a free end. The brake part 12 is connected to the inner side of the fender body 11, and the brake part 12 is at least one boss 121 connected to the inner wall of the fender body 11 .

Specifically, the brake portion 12 may have a structure that can prevent the wheel 50 from moving, such as a structure that can generate friction after the wheel 50 contacts to decelerate the wheel 50.

One end of the fender body 11 is formed as a pivot end pivotally connected to the seat or bracket, and the free end is the other end opposite to the pivot end. The fender 10 is usually fixed to the vehicle body and installed above the wheel 50 , When stepping on the fender 10, the fender 10 rotates around the pivot end.

Therefore, the mudguard 10 not only has the basic function of mudguarding, but also integrates the braking function. When the mudguard 10 is stepped on, the mudguard body 11 can rotate in the direction close to the wheel 50 and be pressed down, thereby allowing The brake part 12 located inside the inner body of the fender 10 will preferentially interfere with the wheel 50, and then use the friction between the brake part 12 and the wheel 50 to prevent the wheel 50 from continuing to rotate, thereby completing the braking action to slow down or stop the rolling of the wheel 50 , Resulting in a better braking effect. On the other hand, when using the mudguard 10 to brake, the user can directly feel the braking force, and can adjust the pedaling depth and force in real time to achieve the purpose of real-time adjustment of the vehicle speed, and this way the brake foot It feels better, the strength of the brake can change with the change of the user's strength, and in addition, the brake structure is simplified to make the appearance more beautiful.

As shown in FIG. 1, the top surface of the boss 121 is formed as a braking surface, and the braking surface is an arc surface matching the outer peripheral surface of the wheel 50. Wherein, the boss 121 is convex compared to the inner surface of the body of the brake portion 12, and the brake surface is also the friction surface contacting the wheel 50. As a result, the curved braking surface can increase the contact area between the tire tread of the wheel 50 and the braking portion 12 during braking, and the braking response is faster, and because the friction angle is more closely aligned, it can increase the contact area between the tire tread of the wheel 50 and the braking portion 12 during braking. Reduce the wear on the tread. The brake surface is closer to the wheel 50 than the inner side of the fender body 11, so as to ensure that the wheel 50 can preferentially contact the brake portion 12 to decelerate or stop the wheel 50.

In the embodiment shown in FIG. 1, the top surface of the boss 121 is formed as a braking surface, and the braking portion 12 has a plurality of concave holes 1211 penetrating the braking surface or a plurality of protrusions formed on the braking surface. Wherein, the braking portion 12 may be a plurality of concave holes 1211 penetrating the braking surface, or a braking surface formed by a plurality of protrusions. The brake part 12 formed by the recessed hole 1211 allows the recessed hole 1211 to filter the blocked tire seam of the wheel 50 on the wheel 50, thereby enhancing the braking effect; using the brake part 12 formed by the protrusion, the protrusion will directly interact with the wheel 50 Conflict, so as to ensure that the braking effect of the wheel 50 is better. Therefore, by providing concave holes 1211 or protrusions penetrating the brake surface on the brake portion 12, on the one hand, the brake surface and the tire are in multi-point contact, which has an effect similar to "spot braking" and can avoid large-area contact. On the other hand, the arrangement of concave holes 1211 or protrusions can strengthen the structure of the brake part 12 and improve the ability of the brake part 12 to resist impact.

In the specific embodiment shown in FIG. 1, the brake portion 12 is provided with a plurality of concave holes 1211 penetrating the braking surface. The plurality of concave holes 1211 can also be formed as a muffler cavity to eliminate a part of the friction noise generated by braking, and the concave The arrangement of the holes 1211 can also save materials, reduce the weight of the mudguard 10, and reduce production costs.

Referring to FIG. 1, the inner side of the mudguard body 11 has a lower convex portion 111 protruding toward the side where the accommodation space is located, and the brake portion 12 is at least partially connected to the top surface of the lower convex portion 111. Therefore, the brake part 12 is arranged at the place where the distance between the fender body 11 and the wheel 50 is the smallest, and the brake part 12 preferentially contacts the wheel 50 during braking, so that the braking effect becomes more obvious. The fender body 11 has a lower convex portion 111 protruding toward the side where the accommodation space is located. The brake portion 12 is at least partially connected to the inner side of the lower convex portion 111, and the outer side of the lower convex portion 111 is formed opposite to the fender body 11 A recessed groove 1111 on the outer surface. In this way, the lower convex portion 111 can further improve the strength of the mudguard 10 in the area where the brake portion 12 is located, and the groove 1111 can also provide the user with an indication function. The user only needs to step on the position of the groove 1111 to achieve more accurate Brake, in addition, the groove 1111 also has an anti-skid effect, reducing the safety hazard of pedaling and slipping.

In some specific embodiments, the distance between the lower convex portion 111 and the arc-shaped outer surface of the mudguard body 11 gradually decreases from the pivotal end to the free end. In this way, as the user steps on the fender 10, the pivot end does not rotate and the free end is close to the wheel 50, so the form of reducing the distance between the lower protrusion 111 and the outer surface of the fender body 11 can allow The area where the convex portion 111 effectively contacts the wheel 50 during braking increases, thereby enhancing the braking effect of the mudguard 10. Further, from the pivotal end to the free end, the depth of the groove 1111 gradually decreases.

In some specific embodiments, the outer surface of the mudguard body 11 is provided with at least one lower protrusion 111 opposite to the lower protrusion 111. Wherein, the lower convex portion 111 and the lower convex portion 111 both extend from the pivotal end to the free end. Therefore, the lower convex portion 111 provided on the outer surface of the mudguard 10 increases the contact area of the user when stepping on the mudguard 10, and facilitates the user's braking operation.
