Technical Field
[0001] The utility model belongs to the field of automobile parts, and in particular relates to a fender mounting structure and an automobile. Background Art
[0002] like Figure 1 As shown, the fender mounting frame 1 in the conventional fender mounting structure is a drooping long cantilever structure that is bent downward and inward in multiple dimensions (i.e., bent in the -Z direction and simultaneously bent in the Y direction toward the inside of the vehicle body). This fender mounting structure has the following problems: (1) After being bent in multiple dimensions in two spatial directions, it is difficult to ensure its own manufacturing accuracy; (2) The lower connecting member 10 that is welded and matched with the fender mounting frame 1 needs to be made into an arc-shaped cantilever structure, and the manufacturing accuracy is also difficult to ensure, which is not conducive to achieving accuracy quickly; (3) When connecting with the front upper member 8, an upper connecting bracket 9 needs to be added as an intermediate connecting member, which is not conducive to reducing costs and leads to increased costs; (4) After a collision occurs, the force transmission path is from the lower connecting member 10 to the fender mounting frame 1, and is transmitted obliquely from bottom to top. It is a force transmission path formed by split welding, and the force transmission strength is not good.

[0039] like Figure 3 , Figure 4 , Figure 8 As shown, in some embodiments, the front cover hinge mounting reinforcement plate 6 has a horizontal portion and a vertical portion connected to each other (the front cover hinge mounting reinforcement plate 6 is approximately in the shape of a "7"), two hinge mounting holes are arranged at intervals on the vertical portion of the front cover hinge mounting reinforcement plate 6, and a first projection welding nut 61 is welded at the position corresponding to the hinge mounting holes, the horizontal portion of the front cover hinge mounting reinforcement plate 6 is welded to the rear portion of the lower side wall of the horizontal mounting plate 11, and the vertical portion of the front cover hinge mounting reinforcement plate 6 is welded to the rear portion of the inner side wall of the vertical mounting plate 12, and the two hinge mounting holes correspond to the two hinge mounting through holes 15 on the vertical mounting plate 12.

The blocking type reinforcement flange 72 increases the strength of the front cover strut mounting nut plate 7, and the front cover strut mounting nut plate 7 can be used to complete the installation function of the front cover strut.
[0041] By welding the above-mentioned fender bracket 2, headlight bracket connector 3, fender front mounting bracket 4, fender mounting front reinforcement 5, front cover hinge mounting reinforcement plate 6, front cover strut mounting nut plate 7 to the fender mounting frame 1, the corresponding functional requirements can be effectively met, and strong support can be provided for the achievement of precision and strength, thereby better helping to achieve the quality of the front face appearance.
[0042] like Fig.10As shown, since the fender mounting frame 1 is a sheet metal part with an arc that only bends toward the inside of the vehicle body in the front-to-back direction, the front reinforcement 100 of the engine side beam does not need to be made into a drooping arc structure, which reduces the difficulty of matching. The lower connecting member 10 that matches the fender mounting frame 1 can be made into a vertical structure in the up-down direction, avoiding arc overlap, reducing the difficulty of manufacturing, and reducing the operation process and manufacturing cost during manufacturing. At the same time, since the fender mounting frame 1 is only bent toward the inside of the vehicle body in the front-to-back direction, the front upper component 8 is directly connected to the front end of the fender mounting frame 1 reinforced by the fender mounting front reinforcement 5, and there is no need to add an additional upper connecting bracket for intermediate connection, which reduces parts and tooling, is conducive to lightweight and simplification of the vehicle body, and reduces costs. In the event of a collision, the force is directly transmitted in the Y direction by the integral structure of the fender mounting frame 1, which is conducive to improving strength and optimizing performance.
[0043] An embodiment of the utility model further provides a car, which comprises the above-mentioned fender mounting structure.
