[0028] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0029] See also Figure 1 and Figure 2 In one embodiment, a retractable motorcycle rear fender includes: a fender body 1 and a retractable cover assembly 2.

[0030] In one embodiment, the fender body 1 as a whole matches with the motorcycle tire, is arc-shaped, and is provided with a cavity 11 and an opening 12 connected to the cavity 11, and the cavity 11 is arranged along the extension direction of the fender body 1. Preferably, the cross section of the cavity 11 near the opening 12 is trapezoidal, and gradually becomes smaller from the opening 12 inward. With this structure, not only the contact area between the telescopic cover assembly 2 and the inner wall of the cavity 11 is increased, but also the movement of the telescopic cover assembly 2 is limited. A strip groove 13 is provided on the upper outer wall of the fender body 1, and the strip groove 13 is connected to the cavity 11.

[0031] Brackets 14 are symmetrically arranged on both sides of the fender body 1, and ear plates are welded at the ends of the brackets 14. The ear plates are provided with mounting holes, which are fixedly connected to the motorcycle frame by bolts. The arrangement of the brackets 14 facilitates the fender body 1 to be fixedly installed on the motorcycle frame by bolts.

[0032] In one embodiment, the telescopic cover assembly 2 is slidably inserted into the cavity 11 , and as the telescopic cover assembly 2 slides out of the opening 12 , the telescopic cover assembly 2 expands along the extension direction of the fender body 1 .

[0033] Specifically, the telescopic cover assembly 2 includes a slide plate 21, a support rod 22, a first spring 23 and a telescopic cover body 24. The slide plate 21 is slidably installed in the cavity 11, a slide groove 212 is provided at the bottom of the slide plate 21, and a slide platform 16 corresponding to the slide groove 212 is provided in the cavity 11, and the slide plate 21 slides smoothly and directionally in the cavity 11.

[0034] The slide plate 21 is equipped with a sliding member 211, which passes through the strip groove 13 and out of the fender body 1, so as to facilitate the operation of the user. The sliding member 211 is a clamping bolt, and a threaded hole is provided on the end surface of the slide plate 21 near the strip groove 13, and one end of the clamping bolt is provided with an external thread, which is threadedly connected with the threaded hole; the other end of the clamping bolt passes through the strip groove 13 and extends out of the fender body 1, and the clamping bolt slides along the strip groove 13, driving the slide plate 21 to slide in the cavity 11.

[0035] There are two groups of support rods 22, one end of each group of support rods 22 is hingedly mounted on the slide plate 21, and the other end of the support rod 22 passes through the cavity 11 toward the opening 12. A first spring 23 is connected between the two groups of support rods 22, and the first spring 23 is close to the hinge position. Under the action of the first spring 23, the support rod 22 opens along the width direction of the cavity 11.

[0036] The two side edges of the telescopic cover 24 are respectively installed on the two groups of support rods 22. Preferably, the telescopic cover 24 is made of a rubber diaphragm, and the rubber diaphragm is wavy, so that the telescopic cover 24 can be folded or unfolded with the support rods 22.

[0037] Normally, the telescopic cover assembly 2 is retracted in the cavity 11. When it rains or in other circumstances, when the telescopic cover assembly 2 needs to be opened, loosen and pull the clamping bolt to slide along the strip groove 13, the slide plate 21 moves toward the opening 12, and the support rod 22 gradually extends out of the opening 12. The support rod 22 extending out of the opening 12 eliminates the constraint of the inner wall of the cavity 11 and opens outward along the width direction of the fender body 1 under the action of the first spring 23. At this time, the width of the telescopic cover body 24 is greater than the width of the fender body 1. The telescopic cover body 24 not only extends the length of the fender body 1, but also expands the area of ​​the fender body 1 in the width direction to block mud and water, thereby improving the performance of blocking mud and water, especially when mud or gravel flies out from the side and bottom of the fender body 1, which is more suitable for areas with poor road conditions, thereby expanding the mud blocking range and mud blocking effect of the fender body 1.

[0038] On the basis of the above embodiment, in order to increase the tension of the telescopic cover 24 and enhance the mud-blocking effect, a second spring 25 is provided between the ends of the two groups of support rods 22 away from the skateboard 21. The second spring 25 further provides a supporting force to open the two groups of support rods 22. Preferably, the free length of the second spring 25 is greater than the width of the mudguard body 1. The second spring 25 is exposed on one side of the mudguard body 1 and shrinks as the support rods 22 are retracted. When the telescopic cover 24 is unfolded, the second spring 25 is supported between the two groups of support rods 22.

[0039] In one embodiment, after the telescopic cover 24 is retracted, in order to reduce the mud, especially gravel, adhering to the telescopic cover, which is easy to wear the telescopic cover 24 during retraction, a brush 15 is attached around the opening 12 to brush off the mud or gravel.

[0040] In the telescopic rear fender of the motorcycle of the present embodiment, the telescopic cover assembly 2 is usually folded in the cavity 11. When it is needed to be used, the clamping bolt is first loosened, and the clamping bolt no longer presses against the outer wall of the fender body 1, and then the user pulls the clamping bolt to slide along the strip groove 13, and the slide plate 21 moves toward the opening 12, driving the support rod 22 to extend out of the opening, and the support rod 22 opens outward along the width direction of the fender body 1 under the supporting force of the first spring 23, and the telescopic cover body 24 is unfolded accordingly. When the telescopic cover body 24 is stretched to the required length, the user tightens the clamping bolt again to perform mud blocking. After use, the clamping bolt is loosened and pulled, and the support rod 22 and the telescopic cover body 24 are folded in the cavity 11, and the clamping bolt is tightened.

[0041] Beneficial effects of the utility model:

[0042] The telescopic rear fender of a motorcycle is provided with a telescopic cover assembly 2 on the fender body 1. The telescopic cover assembly 2 is usually folded in the fender body 1 to maintain the overall appearance of the motorcycle. When the telescopic cover assembly 2 extends from the fender body 1, the fender body 1 is extended in length and width, thereby expanding the area of ​​mud and water blocking and improving the mud and water blocking performance of the fender body 1 on the side, which is particularly suitable for areas with poor road conditions. A second spring 25 is provided between the ends of the two groups of support rods 22 away from the slide plate 21 to increase the tension of the telescopic cover body 24 and enhance the mud blocking effect.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
