[0027] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0028] See also Figure 1 , Figure 2 and Figure 4 The fender 100 of the first embodiment includes a bent connecting piece 10 and a long strip fender body 20. The cross section of the fender body 20 is as follows: Figure 4 The first fan ring shown in the figure can be used to make the contour of the fender body 20 better match the shape of the wheel, so that the mud guarding effect of the fender body 20 is better; optionally, Figure 4As an example, the central angle α occupied by the first fan ring is 80 to 90 degrees. For example, the central angle α occupied by the first fan ring is 80, 81, 82, 83, 84, 85, 86, 87, 88, 89 or 90 degrees. The purpose of this design is to prevent the central angle α occupied by the first fan ring from being too large. Obviously, according to actual needs, the central angle α occupied by the first fan ring can also be other.

[0029] At the same time, the upper side 22 of the fender body 20 is provided with a convex rib 24 protruding outwardly, and the convex rib 24 is arranged along the front-back direction of the fender body 10; Figure 1 and Figure 3 As an example, the convex rib 24 is located at the center of the upper side 22 of the fender body 20. The purpose of this design is to strengthen the structure of the fender body 20 from the center of the fender body 20, so as to further avoid the problem of serious bending deformation of the fender body 20 due to the excessive hanging length of the rear end 25. In addition, the convex rib 22 extends to the front end 21 and the rear end 25 of the fender body 20 respectively, so as to effectively extend the length of the convex rib 22, so as to strengthen the strength of the fender body 20 from the length direction of the convex rib 22.

[0030] Furthermore, the connecting piece 10 includes a front connecting portion 11 located in front of the fender body 20 and a rear connecting portion 12 connected to the front connecting portion 11. The rear connecting portion 12 is fixed to the front end 21 of the fender body 20 in a stacked manner, so that the rear connecting portion 12 and the front end 21 of the fender body 20 form a double-layer structure; the front connecting portion 11 is also bent upward relative to the rear connecting portion 12, and the state is shown in FIG. Figure 1 as shown; optionally, Figure 2 As an example, the connecting piece 10 further includes an intermediate connecting portion 13, the front connecting portion 11 is connected to the rear connecting portion 12 through the intermediate connecting portion 13, the rear connecting portion 12 extends along the left and right direction of the fender body 20 and protrudes from the intermediate connecting portion 13, and an arc transition structure 14 is provided between the intermediate connecting portion 13 and the rear connecting portion 12, so as to avoid stress concentration between the rear connecting portion 12 and the intermediate connecting portion 13 and cracks between the rear connecting portion 12 and the intermediate connecting portion 13 due to stress concentration by means of the arc transition structure 14; at the same time, by means of the rear connecting portion 12 protruding from the intermediate connecting portion 13, the matching area between the rear connecting portion 12 and the front end 21 of the fender body 20 is increased. More specifically, as follows:

[0031] like Figure 4As shown, as an example, the cross-sectional outer contour 24a of the convex rib 24 includes a central arc 241 in the middle and lateral arcs 242 tangentially distributed on both sides of the central arc 241, that is, the lateral arc 242 is arranged tangentially to the central arc 241, and the center of the lateral arc 242 and the central arc 241 are oriented in different directions. Figure 4 As an example, the center of the lateral arc 242 is arranged upward, and the center of the central arc 241 is arranged downward; the purpose of this design is to avoid stress concentration at the intersection of the rib 24 and the upper side 22 of the fender body 20, and to avoid cracking at the intersection of the rib 24 and the upper side of the fender body 20 due to stress concentration, thereby ensuring the stability and reliability of the combination of the rib 24 and the upper side 22 of the fender body 20.

[0032] Another example Figure 4 As shown, as an example, the cross section of the rear end connecting portion 12 is as follows Figure 4 The second fan ring shown is closely matched with the first fan ring, so that the rear connecting portion 12 and the front end 21 of the fender body 20 fit more closely. Figure 4 As an example, the second fan ring is arranged inside the first fan ring, and the center angle β of the second fan ring is 70 to 80 degrees. For example, the center angle β of the second fan ring is 70, 71, 72, 73, 74, 75, 76, 77, 78, 79 or 80 degrees, so as to control the second fan ring not to protrude from the first fan ring in the circumferential direction, thereby making the fender 100 of the first embodiment more concise. Figures 1 to 4 As an example, the rear end connection portion 12 is riveted to the front end 21 of the fender body 20 by means of rivets 30, so as to simplify the assembly connection relationship between the rear end connection portion 12 and the front end 21 of the fender body 20, and also make the fixation of the rear end connection portion 12 and the front end 21 of the fender body 20 more reliable; optionally, Figure 4 As an example, there are two rivets 30 arranged on the left and the right, and the two rivets 30 are symmetrical to each other with the rib 24 as the center. This design can increase the number of riveted fixing positions between the rear end connection part 12 and the front end 21 of the fender body 20, thereby making the rear end connection part 12 and the front end 21 of the fender body 20 fixed as a whole stable and reliable.

[0033] For example Figure 4As shown, as an example, the fender body 20 includes a metal inner sheet 20a and a cover 20b covering the outside of the metal inner sheet 20a, so that the metal inner sheet 20a can be used to increase the rigidity of the fender body 20, and the cover 20b can be used to prevent the metal inner sheet 20a from being corroded and damaged by muddy water; in addition, the fender body 20 includes the metal inner sheet 20a and the cover 20b, so the fender body 20 and the convex rib 24 can be formed at one time by an in-mold forming method, and since the cross-sectional profile 24a of the convex rib 24 includes a central arc 241 in the middle position and lateral arcs 242 tangentially distributed on both sides of the central arc 241, it is convenient to demould the fender body 20 and the convex rib 24. Specifically, as an example, the metal inner sheet 20a is a steel sheet, and the cover 20b is a plastic body, but it is not limited to this.

[0034] like Figures 1 to 3 As shown, the fender 100 of the first embodiment further includes a bolt 40 inserted into the front connecting portion 11 and a nut 50 threadedly connected to the bolt 40 , so that the front connecting portion 11 is fixed to the vehicle frame by the cooperation of the bolt 40 and the nut 50 .

[0035] See also Figures 5 to 7 The structures of the fender 100 of the second embodiment are substantially the same as those of the fender 100 of the first embodiment, and the difference lies in the middle connecting portion in the connecting piece, as follows:

[0036] In the fender 100 of the second embodiment, the middle connecting portion 13 of the connecting piece 10 includes a first straight segment 131, a first arc segment 132, a second arc segment 133 and a second straight segment 134. The first arc segment 132 is tangentially connected to the first straight segment 131 and the second arc segment 133 respectively, the second arc segment 133 is also tangentially connected to the second straight segment 134, the second straight segment 134 is also connected to the front connecting portion 11, and the first straight segment 131 is also connected to the rear connecting portion 12; the arc centers of the first arc segment 132 and the second arc segment 133 are oriented in different directions, for example, at Figure 7 As an example, the arc center of the first arc segment 132 is arranged downward, the arc center of the second arc segment 133 is arranged upward, and the arc diameter R2 of the second arc segment 133 is greater than the arc diameter R1 of the first arc segment 132. Figure 7 As shown. The middle connecting portion 13 is designed to include a first straight segment 131, a first arc segment 132, a second arc segment 133 and a second straight segment 134, so that the first arc segment 132, the second arc segment 133, the second straight segment 134 and the front connecting portion 11 define a avoidance space 15, and the avoidance space 15 can provide an avoidance position for the arrangement of the brake line. Therefore, the mudguard 100 of the second embodiment is suitable for mud blocking the rear wheel and is installed at a position of the frame adjacent to the rear wheel.

[0037] In the fender 100 of the first embodiment, the middle connecting portion 13 of the connecting piece 10 is a straight line segment and is much shorter than the middle connecting portion 13 of the connecting piece 10. Figure 2 As shown, the mudguard 100 of the first embodiment is suitable for protecting the front wheel from mud and is mounted on the frame at a position adjacent to the front wheel.

[0038] Apart from the above differences, the other two are the same, so I will not go into details here.

[0039] Finally, the utility model also provides a bicycle, which includes the aforementioned mudguard 100 (100'). Since the specific structure of the mudguard 100 (100') has been described above, and other structures of the bicycle are well known in the art, they will not be described here.

[0040] Compared with the prior art, the structural strength of the fender body 20 with a cross-section of the first fan ring is increased by setting the rib 24, thereby preventing the long fender body 20 from bending and deforming due to the front end 21 being supported by the connecting plate 10 and the rear end 25 being suspended; the rear end connecting part 12 is fixed together with the front end 21 of the fender body 20 in a stacked manner, saving the customer's assembly operation steps; the front end connecting part 11 is also bent upward relative to the rear end connecting part 12, so as to facilitate the assembly operation with the frame.

[0041] It is worth noting that the direction indicated by arrow A in the accompanying drawings is the direction from front to back of the fender body 20, and the direction indicated by arrow B in the accompanying drawings is the direction from left to right of the fender body 20. In addition, although the accompanying drawings show that the rib 24 is located on the upper side 22 of the fender body 20, it is obvious that according to actual needs, the rib 24 can also be located on the lower side 23 of the fender body 20, or the rib 24 can be located on the upper side 22 and the lower side 23 of the fender body 20, so it is not limited to the drawings. It is understandable that when the rib 24 is located on the lower side 23 of the fender body 20, the rib 24 can be located at the center of the fender body 20; when the rib 24 is located on the upper side 22 and the lower side 23 of the fender body 20, the rib 24 can be located at the center of the upper side 22 of the fender body 20 and the center of the lower side 23 of the fender body 20.
