[0029] See also Figures 1 to 5 The present application provides a fender mounting structure for connecting a fender 100 and a side panel front connecting plate 200. Specifically, it includes a main body 10 and a reinforcement structure 20. Among them, the main body 10 includes a fender connecting portion 11 and a side panel connecting portion 12. The fender connecting portion 11 is arranged from the main body 10 in the Y direction, and is used to connect the fender 100. The side panel connecting portion 12 is arranged from the main body 10 in the Z direction. And along the Z direction, a plurality of welding portions 13 are arranged at intervals on the side panel connecting portion 12, which are used to connect the side panel front connecting plate 200. The side panel connecting portion 12 and the side panel front connecting plate 200 are fixedly connected by welding, and the fender connecting portion 11 and the fender 100 can be connected by welding or screwing.

[0030] Furthermore, the fender connecting portion 11 and the side panel connecting portion 12 are an integrated structure, and the integrated structure here refers to being obtained through integrated processing. In this embodiment, the body 10 is a sheet metal part, and the upper part of the body 10 is bent in the Y direction to form the fender connecting portion 11, and the remaining unbent part becomes the side panel connecting portion 12. Of course, it is not limited to this. In other embodiments, the fender connecting portion 11 and the side panel connecting portion 12 can also be a split structure, connected by welding, screwing, etc.

[0031] Specifically, the reinforcement structure 20 includes a reinforcement rib 21 disposed on the side enclosure connection portion 12, and the reinforcement rib 21 is extended along the Z direction. The reinforcement rib 21 is provided to strengthen the structural strength of the side enclosure connection portion 12, improve the structural stability of the side enclosure connection portion 12, and ensure that the length of the side enclosure connection portion 12 does not need to be too long to ensure that the final installation point stiffness meets the standard.

[0032] Preferably, along the Z direction, the reinforcing rib 21 penetrates the side enclosure connection portion 12 from top to bottom. Penetrating here means that the length of the reinforcing rib 21 is the same as the length of the side enclosure connection portion 12, and the two ends of the reinforcing rib 21 are just located at the upper and lower edges of the side enclosure connection portion 12, thereby maximizing the structural strength of the side enclosure connection portion 12.

[0033] Furthermore, the reinforcing rib 21 protrudes from the side of the side enclosure connecting portion 12 away from the side enclosure front connecting plate 200. That is, there is no structural protrusion on the side where the side enclosure connecting portion 12 is welded to the side enclosure front connecting plate 200, ensuring that the welding portion 13 can be firmly welded to the side enclosure front connecting plate 200. Preferably, the reinforcing rib 21 is provided at the middle position of the side enclosure connecting portion 12.

[0034] In one embodiment, the reinforcement structure 20 further includes a first flange 22 disposed on the side enclosure connection portion 12 , and the first flange 22 extends along the Y direction, so that the structural strength of the side enclosure connection portion 12 is further enhanced by the first flange 22 .

[0035] Furthermore, the first flange 22 is provided at the edge of the side enclosure connection portion 12, and is formed by directly bending the outer edge of the side enclosure connection portion 12. The processing operation is simple, and the strength of the side enclosure connection portion 12 can be strengthened in multiple directions. Preferably, the first flange 22 is bent in a direction away from the side enclosure front connection plate 200, which also ensures that there is no structural protrusion on the side where the side enclosure connection portion 12 is welded to the side enclosure front connection plate 200, thereby improving the connection strength. Preferably, the angle between the first flange 22 and the side enclosure connection portion 12 is 90°.

[0036] In one embodiment, the reinforcement structure 20 further includes a second flange 23 disposed on the fender connecting portion 11 , and the second flange 23 extends along the Z direction, so that the structural strength of the fender connecting portion 11 is further enhanced by the second flange 23 .

[0037] Furthermore, the second flange 23 is provided at the edge of the fender connecting portion 11, and is formed by directly bending the outer edge of the fender connecting portion 11, which is easy to process and can multi-directionally strengthen the strength of the fender connecting portion 11. Preferably, the angle between the second flange 23 and the fender connecting portion 11 is 90°.

[0038] In one embodiment, the reinforcement structure 20 further includes a convex rib 24 disposed on the main body 10 , and the convex rib 24 is disposed along the Y direction to further enhance the structural strength of the side enclosure connection portion 12 .

[0039] Furthermore, the body 10 is provided with an opening 14, which is located above the welding portion 13 and does not affect welding. The provision of the opening 14 reduces the weight and consumables of the body 10 to a certain extent. The opening 14 is preferably provided at the connection between the fender connecting portion 11 and the side panel connecting portion 12.

[0040] In this embodiment, the welding parts 13 can be set in two or more groups. In this embodiment, two groups are set, and the two groups of welding parts 13 are distributed up and down. Each group of welding parts 13 includes at least two welding points 131, and two are set in this embodiment. The two welding points 131 are distributed on both sides of the reinforcing rib 21, and the welding effect is more solid. The welding points 131 here can be placed in the solder welding or directly welded to ensure the welding effect.

[0041] Through the coordination of the above-mentioned reinforcement structure 20 and the weld 13, the fender mounting structure greatly solves the problem of too long cantilever while taking into account the pedestrian protection regulations, improves the dimensional stability of the fender 100 bracket, improves the compliance rate of the front connecting plate assembly, and solves the problems of large assembly error and mounting point stiffness. After CAE analysis and verification, the Y-direction stiffness of the fender 100 mounting point of this structure can be significantly improved to more than 100, and the Z-direction stiffness can be improved to more than 150 (Y-direction 105, Z-direction 153), and the optimization effect is significant.

[0042] The present application also provides an automobile, which includes a fender 100, a side panel front connecting plate 200, and a fender mounting structure of any of the above embodiments, wherein a joint 101 is provided on the fender 100, and the fender mounting structure is connected to the joint 101 via a connecting member 102. The connecting member 102 can be a screw, solder, adhesive, etc., and in this embodiment, a screw is used for easy disassembly and assembly.

[0043] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
