[0003] To improve off-road performance, certain models require increased wheel clearance. Consequently, the fenders must also create more space for the wheels to move up and down, preventing them from interfering with potholes. This requires the removal of a portion of the fender's top structure, which results in insufficient rigidity. In the event of a collision, the fender's top is prone to denting and deformation. Furthermore, gaps between the fender's top and the fender can create light leakage.

[0004] At present, an integral double-layer plate structure is usually used for installation to solve the problem of insufficient wheel arch rigidity, but this structure will increase production costs, and foam strips need to be installed between the top of the wheel arch and the fender to solve the problem of light leakage between the top of the wheel arch and the fender.

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1-5 As shown, a local reinforcement structure for a fender flare is primarily used around the wheels of a vehicle and includes a fender 100, a fender body 200, and a bracket 300. The fender body 200 is disposed on and outside the fender 100. The fender body is curved, protecting the fender 100 from damage while also decorating the side of the vehicle and adding a layered feel. The bracket 300 is disposed on the inner side of the top of the fender body 200 and is provided with support ribs 310 that can abut against the fender 100. When the fender body 200 is impacted, the support ribs 310 abut against the fender 100, thereby supporting the top of the fender body 200 and preventing it from denting or deforming. The local reinforcement structure of the automobile fender can prevent the fender body 200 from being dented or deformed in the event of a collision by installing a bracket 300 on the inner side of the fender body 200, and supporting the top of the fender body 200 with support ribs 310 on the bracket 300. Compared with the overall double-layer plate structure in the prior art, it can reduce production costs.

[0031] A plurality of support ribs 310 are provided, and the plurality of support ribs 310 are arranged along the length direction of the bracket 300. The plurality of support ribs 310 can support multiple positions on the top of the fender body 200, further preventing the fender body 200 from being dented or deformed in the event of a collision.

[0032] The bracket 300 is provided with a first positioning surface 320 and a second positioning surface 330. The top of the fender body 200 is provided with a third positioning surface 210 and a fourth positioning surface 220. The first positioning surface 320 is aligned with the third positioning surface 210, and the second positioning surface 330 is aligned with the fourth positioning surface 220. By aligning the first positioning surface 320 with the third positioning surface 210 and the second positioning surface 330 with the fourth positioning surface 220, the bracket 300 can be positioned, ensuring accurate installation of the bracket 300.

[0033] The fender bulge body 200 is provided with a connecting rib 230, and the bracket 300 is provided with a mounting hole 340. The connecting rib 230 passes through the mounting hole 340 and is fixedly connected to the bracket 300. After the connecting rib 230 passes through the mounting hole 340 and is fixedly connected to the bracket 300, it can prevent the bracket 300 from separating from the fender bulge body 200.

[0034] Multiple connecting ribs 230 and mounting holes 340 are provided, with multiple connecting ribs 230 arranged along the length of the bracket 300. The multiple connecting ribs 230 can pass through the multiple mounting holes 340 and be fixedly connected to the bracket 300. Multiple connecting ribs 230 can secure the bracket 300 at multiple locations, providing a better securing effect.

[0035] The connecting rib 230 is welded to the bracket 300. This welding connection effectively prevents deformation of the fender flare body 200 due to multiple installation positions. Preferably, hot melt welding is used to avoid surface stress marks caused by puncture welding. Furthermore, after welding, the resulting mushroom head 341 needs to be 1.5 mm thick, with a 1.5 mm margin on both sides to ensure installation strength.

[0036] A shielding plate 350 is provided at the bottom of the bracket 300 and abuts against the fender 100. The shielding plate 350 can block light and prevent light leakage. Compared with the existing technology, this fender brow reinforcement structure eliminates the foam strip on the top of the fender brow body 200, which can reduce production costs.

[0037] The fender body 200 is provided with a first clamping block 240, and the fender 100 is provided with a second clamping block 110. The first clamping block 240 is clamped with the second clamping block 110. The fender body 200 is mounted on the fender 100 by clamping, which reduces the difficulty of installing the fender body 200.

[0038] Multiple first and second clamping blocks 240 and 110 are provided; the multiple first clamping blocks 240 are arranged along the length of the fender body 200 and are respectively clamped with the multiple second clamping blocks 110. This allows the fender body 200 to be clamped to the fender 100 at multiple different positions, achieving a better fixing effect.

[0039] The bracket 300 is provided with a clearance hole 360; one of the first engaging blocks 240 passes through the clearance hole 360 ​​and engages with one of the second engaging blocks 110. The clearance hole 360 ​​allows the top of the fender bulge body 200 to be engaged with the fender 100, preventing the top of the fender bulge body 200 from tilting. Preferably, both sides of the bracket 300 are provided with notches; the two first engaging blocks 240 respectively pass through the two notches and engage with the two second engaging blocks 110, further securing the top of the fender bulge body 200 and preventing it from tilting.

[0040] This solution provides a localized fender reinforcement structure for an automobile, comprising a fender 100, a fender body 200, and a bracket 300. The bracket 300 is mounted on the inner side of the fender body 200, and the top of the fender body 200 is supported by support ribs 310 on the bracket 300, preventing the fender body 200 from denting or deforming in the event of a collision. Furthermore, a shielding plate 350 is provided on the bracket 300 to block light and prevent light leakage.
