[0002] As consumers' demands for car appearance become more and more diversified, OEMs have also put forward higher requirements for the aesthetic appearance of cars. The main function of wheel arches is to be used for decoration, scratch protection and the personalized needs of drivers. At the same time, they must meet aerodynamic requirements and reduce the drag coefficient. The wheel arch decorative parts in the existing technology are connected to the bumper and the outer surface of the car body by snaps. After the wheel arches are assembled, there will be a gap with the matching parts, which seriously affects the exquisite appearance of the vehicle. The usual solution is to reduce the gap with the matching parts by improving the precision of the wheel arch single piece. This method requires continuous modification of the wheel arch mold and debugging of the product to reduce the gap by tightening it with the car body. However, the wheel arch mold is generally large, and the disassembly and assembly process is time-consuming and labor-intensive, thereby increasing the cost of parts development.

DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-8 As shown, the utility model provides a wheel eyebrow transition bracket mounting structure, including a fender 1, a wheel eyebrow body 2, a transition bracket 3 and a snap nail 4. The cross-section of the fender 1 and the wheel eyebrow body 2 is an L-shaped flange structure bent toward the interior of the vehicle. The outer surface of the fender 1 is provided with a square hole 11, the inner surface of the wheel eyebrow body 2 is provided with a snap seat 21, and the outer surface of the transition bracket 3 is provided with upper and lower snap-on inclined surfaces 32. The front bottom surface is provided with a sponge block 31, the front top surface is provided with a sink 33 for accommodating the front of the snap nail 4, and the tail is provided with a recessed groove 33. 4; the transition bracket 3, with its recessed groove 34, has its beveled engaging surface 32 installed in the square hole 11 on the fender 1. The sponge block 31 fits against the outer surface of the fender 1. The sponge block 31 is compressed, creating an interference fit between the beveled engaging surface 32 and the fender 1, preventing it from coming out of the square hole 11. The front portion 41 of the clip pin 4 is clipped onto the clip seat 21 of the fender body 2, while the rear end of the clip pin 4 is clipped into the recessed groove 34 at the rear end of the transition bracket 3. This connection ensures that the fender can remain usable even after repeated disassembly.

[0022] The fender 1 is made of metal stamping, and the square holes 11 on its outer surface are punched holes for clamping the transition bracket 3.

[0023] The wheel arch body 2 is semicircular and mounted on the fender, and is provided with a sponge strip 23 and abutment ribs 22. The sponge strip 23 is pasted on the side away from the flange of the wheel arch body 2, and the abutment ribs 22 are integrally injection-molded with the wheel arch body 2, and the abutment ribs 22 abut against the outer surface of the fender 1.

[0024] The transition bracket 3 is T-shaped, and the outer part of the T is provided with upper and lower clamping inclined surfaces. The wheel eyebrow body 2 is installed into the installed transition bracket 3; multiple transition brackets 3 are respectively installed in the square holes 11 of the fender 1, and the wheel eyebrow assembly is assembled as a whole in the installed transition bracket 3 to complete the overall assembly.

[0025] The clip nail 4 includes a clip nail front part 41, a clip nail middle part 42 and a clip nail tail part 43. The clip nail front part 41 is clipped with the clip seat 21 in the cavity of the wheel eyebrow body 2, the clip nail middle part 42 is wrapped in the sink of the transition bracket 3, and the clip nail tail part 4 is clipped into the recessed groove at the tail of the transition bracket 3. Both ends of the clip nail 4 are clipped.

[0026] The transition bracket 3 is formed by integral injection molding, has a cavity inside, and a sponge block is pasted on the front bottom surface.

[0027] During assembly, first install the side of the transition bracket 3 with the recessed groove 34 into the square hole 11 on the fender 1, and the sponge block 31 of the transition bracket 3 fits the outer surface of the fender 1, and the snap-on bevel 32 is snapped into the inner surface of the fender 1. At this time, the sponge block 31 is compressed, and the snap-on bevel 32 forms an interference with the fender 1, limiting its escape from the square hole 11; then install the front part 41 of the clip nail on the clip seat 21 of the wheel eyebrow body 2, snapping it into the snap-on surface 201, and the sponge strip 23 is adhered to the wheel eyebrow body 2 to form a wheel eyebrow assembly; finally, install the wheel eyebrow assembly into the installed transition bracket 3. At this time, the middle part 42 of the clip nail is wrapped in the sink 33 of the transition bracket 3, and the tail part 43 of the clip nail is snapped into the recessed groove 34 of the transition bracket 3, and the abutment rib is in abutment contact with the outer surface of the fender.

[0028] When multiple transition brackets 3 are needed, all transition brackets 3 are first installed in the square holes 11 in the above manner, and then the snap pins 4 are installed on the snap seats 21 to form the wheel eyebrow assembly. Finally, the wheel eyebrow assembly is assembled as a whole in the installed transition brackets 3 to complete the overall assembly.

[0029] This new design utilizes a transition bracket structure to absorb manufacturing variations in matching parts, ensuring a seamless gap between the fender flare and the fender, enhancing the vehicle's refined appearance. Furthermore, it facilitates assembly and disassembly, provides reliable fixation, and eliminates the need to modify large fender flare molds. If further refinement is required during assembly, a smaller transition bracket can be added to the mold, reducing product commissioning cycles and part development costs.

[0030] The above embodiments of the present invention are merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
