The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as a limitation on the utility model.

[0033] As Figures 1-10The utility model provides a fender assembly, fender assembly can be applied to the front wheel or rear wheel of bicycle, folding bicycle, scooter, electric tricycle or electric bicycle. Fender assembly includes fender body 3 and reflector, reflector can be installed in the front end, rear end or side of fender body 3. In the embodiment, fender assembly is applied to electric bicycle, and two reflectors are arranged on the both sides of fender body 3. Fender body 3 is provided with clamping hole 31, and the hole wall of clamping hole 31 is provided with limiting groove 32 extending outward along the radial direction of clamping hole 31. The reflector includes fixedly connected reflector body 1 and plug-in part 2, and the side of reflector body 1 away from plug-in part 2 is connected with a reflecting piece. The reflecting piece can be connected with the reflector body 1 by adhesive bonding or clamping, and the specific structure is the prior art in the field, which will not be described here. The reflector body 1 and the plug-in part 2 can be integrally connected or connected by a fastener. In the embodiment, the reflector body 1 and the plug-in part 2 are integrally connected. The plug-in part 2 includes an integrally arranged connecting column 21, a clamping part 22 and a first limiting part 24. The connecting column 21 is fixedly connected or integrally formed with the reflector body 1. The clamping part 22 and the connecting column 21 form a deformation space 20 therebetween. The clamping part 22 is used for clamping connection with the clamping hole 31. During clamping of the clamping part 22 with the clamping hole 31, the clamping part 22 is elastically deformed inwardly into the deformation space 20 under the action of the side wall of the clamping hole 31, and then the clamping part 22 is restored under the elastic force, thereby achieving clamping with the fender body 3. At the same time, the first limiting part 24 can be attached to the inner side wall of the limiting groove 32, thereby avoiding rotation of the reflector after the reflector is clamped in the fender body 3. By clamping the clamping part 22 of the plug-in part 2 of the reflector with the clamping hole 31, the reflector can be installed in the fender body 3 without using bolts and nuts. At the same time, the deformation space 20 is arranged between the clamping part 22 and the connecting column 21. During clamping of the clamping part 22 with the clamping hole 31 of the fender body 3, the clamping part 22 is elastically deformed inwardly into the deformation space 20, thereby reducing the clamping resistance during installation, reducing the labor intensity of the assembly personnel, and completing the installation without tools, simplifying the assembly steps and improving the operation efficiency.

[0034] Further, the clamping part 22 is provided with a guide surface 221 and a clamping surface 222. The guide surface 221 is located on the side of the clamping part 22 away from the deformation space 20 and extends in a direction away from the deformation space 20. The guide surface 221 is provided as an inclined surface or an arc surface. During installation, the guide surface 221 first contacts the inner surface or edge of the clamping hole 31 and extrudes the clamping part 22, so that the clamping part 22 is elastically deformed inwardly into the deformation space 20. Figure 9As shown, the clamping surface 222 is provided as an inclined surface, and the distance between the clamping surface 222 and the surface of the reflector body 1 increases in the direction away from the axis of the reflector body 1. When the clamping piece passes through the clamping hole 31, the clamping portion 22 elastically deforms and restores under the elastic force of itself. At a certain moment when the clamping portion 22 restores, the clamping surface 222 contacts or adheres to the inner surface of the mudguard body 3. At this time, the clamping portion 22 still has a certain elastic force, and the clamping portion 22 abuts against the mudguard body 3 to achieve axial limiting of the reflector. The moment when the clamping surface 222 contacts or adheres to the inner surface of the mudguard body 3 depends on the thickness of the mudguard body 3. The greater the thickness, the earlier the moment of contact or adhesion. The smaller the thickness, the later the moment of contact or adhesion. By providing the clamping surface 222 as an inclined surface, the clamping requirements of the mudguard body 3 with different thicknesses are met.

[0035] Specifically, as shown in Figures 5-9 , the end of the connecting column 21 away from the reflector body 1 is formed with a flange outward in the radial direction of the reflector body 1. The clamping portion 22 is connected to the flange and extends towards the opposite direction of the reflector body 1, and the clamping portion 22 as a whole presents an arc-shaped plate structure. The clamping portion 22 is spaced apart from the connecting column 21 in a first direction, so as to form a deformation space 20 between the clamping portion 22 and the connecting column 21, as shown in Figure 5 、 Figure 8 and Figure 9 . The first limiting portion 24 is connected to the connecting column 21 in a second direction and extends away from the connecting column 21, so that the first limiting portion 24 can adhere to the inner side wall of the limiting groove 32. As shown in Figures 5-7 , the first direction is indicated by the arrow in A-A direction in Figures 5-7 , and the second direction is indicated by the arrow in B-B direction in Figures 5-7 . The first direction and the second direction are perpendicular or at an angle, and in this embodiment, the first direction and the second direction are perpendicular, so as to ensure that the reflector cannot rotate and move in the first direction after installation, and to avoid that the reflector body 1 is elastically deformed under external force to cause clamping failure.

[0036] Optionally, the clamping portion 22 is provided as two, and the two clamping portions 22 are respectively located on both sides of the connecting column 21 in the first direction, and two deformation spaces are formed between the two clamping portions 22 and the connecting column 21. The structure of the two clamping portions 22 makes the reflector more firmly clamped on the mudguard body 3.

[0037] Further, as shown in Figure 8As shown, the plug-in part 2 further comprises a reinforcing rib 23 arranged in the deformation space 20 and used for connecting the connecting column 21 and the clamping part 22, the reinforcing rib 23 is arranged at the end of the clamping part 22 away from the reflector body 1, so that when the clamping part 22 is elastically deformed, the clamping part 22 has greater elastic potential, finally making the clamping of the reflector and the fender body 3 more closely. And arranging the reinforcing rib 23 in the deformation space 20 reduces the amount of material, improves lightweight while reducing material cost.

[0038] Further, as shown, Figure 7 The plug-in part 2 further comprises a second limiting part 25, the second limiting part 25 is arranged integrally with the connecting column 21, the second limiting part 25 and the first limiting part 24 are respectively located on both sides of the connecting column 21 along the second direction, the second limiting part 25 extends away from the connecting column 21, and is used for abutting with the hole wall of the clamping hole 31. After installation, the second limiting part 25 abuts with the hole wall of the clamping hole 31, limiting the reflector from moving relative to the fender body 3 along the second direction, thereby avoiding the first limiting part 24 from being out of the limiting groove 32.

[0039] Optionally, the first limiting part 24 comprises two parallel limiting plates, and the two limiting plates are respectively used for abutting with the two inner side walls of the limiting groove 32. By arranging the first limiting part 24 as two parallel limiting plates, the amount of material of the limiting part is reduced, and the lightweight and the material cost are reduced. Similarly, the second limiting part 25 is also arranged as two parallel plate structures, which can also improve the lightweight and reduce the material cost.

[0040] Optionally, the connecting column 21 further comprises a weight-reducing hole 211, the weight-reducing hole 211 is coaxially arranged with the reflector body 1, and the weight-reducing hole 211 is arranged to improve the lightweight and reduce the material cost, and effectively disperse the stress at the connecting position of the connecting column 21 and the reflector body 1, thereby reducing the risk of fracture caused by stress concentration.

[0041] The utility model provides a kind of electric bicycle, including the fender assembly in the embodiment of the present application, by setting the fender assembly in the embodiment of the present application, assembly step is simplified, and operation efficiency is improved.
