[0005] The mounting hole of the fender bracket is an X-shaped perforation, which is used for driving a long bolt into and connecting and fixing the fender and the fender bracket.

[0006] The upper and lower ends of the curved bracket are in contact with the inner side of the fender and are provided with a through hole, and the middle part is provided with an arc surface, which is in contact with the back of the groove on the fender. The through hole cooperates with the stud on the fender to complete the positioning and is pre-installed on the inner side of the fender by tightening the nut.

[0007] The cushion block has a curved surface on one side and a flat surface on the other side, with two through holes in the middle. The curved surface fits the cylindrical surface of the fender bracket. The long bolt passes through the two through holes and is tightened, so that the cushion block can prevent loosening and rotation.

[0008] Beneficial effects: The new fender fixing structure proposed by the utility model has a reasonable assembly design and is simple to assemble. The X-shaped perforation of the fender bracket improves the versatility of the fender bracket. From pre-installation to fender positioning, and then to finally tightening the long bolts to complete the assembly of the fender, this process can be completed by one person, thereby improving assembly efficiency and accuracy.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-Figure 7As shown, the utility model provides a vehicle fender fixing structure, including a fender 1, a fender bracket 2, a curved bracket 3, a pad 4, a long bolt and a nut. The outer side of the fender 1 is provided with a semicircular groove 11 that matches the fender bracket 2. The groove 11 is provided with a group of square openings 12 that are symmetrical with respect to the center of the fender 1 and a group of cylindrical protrusions 13. The square openings 12 are used for the long bolts to pass through the fender bracket 2 through the fender 1 and match with the curved bracket 3 to fix the fender 1. The fender 1 A group of studs 14 are respectively provided on the upper and lower sides of the square openings 12 on the inner left and right sides for fixing the curved bracket; the fender bracket 2 is cylindrical, and two groups of positioning holes 21 and mounting holes 22 are provided on the cylinder. The fender bracket 2 is placed in the semicircular groove 11 on the outer side of the fender 1, and the cylindrical protrusion 13 on the fender 1 cooperates with the positioning hole 21 on the fender bracket 2 to realize the positioning of the fender 1; the long bolts pass through the gasket 4, the fender bracket 2, the fender 1, and the curved bracket 3 in turn and are tightened and fixed to complete the assembly.

[0019] The mounting hole 22 of the fender bracket 2 is an X-shaped perforation for driving a long bolt into and connecting and fixing the fender 1 and the fender bracket 2. The X-shaped perforation allows the fender bracket 2 to be used not only at the left and right ends of the frame, but also on fenders facing different directions on the same side, thus having universality.

[0020] The upper and lower ends of the curved bracket 3 are in contact with the inner side of the fender 1 and are provided with a through hole 32, and the middle part is provided with an arc surface 31, and the arc surface 31 is in contact with the back of the groove 11 on the fender 1, and the through hole 32 cooperates with the stud 14 on the fender 1 to complete the positioning, and is pre-installed on the inner side of the fender 1 by tightening the nut.

[0021] The pad 4 has a curved surface 41 on one side and a flat surface on the other side, with a second through hole 42 provided in the middle. A nut is welded on the flat surface at the second through hole 42. The curved surface 41 fits the cylindrical surface of the fender bracket 2. The long bolt passes through the second through hole 42 and is tightened. The pad 4 can prevent loosening and rotation.
