Technical Field
[0001] This utility model relates to the field of automobile shells, and in particular to a double-layer structure wheel arch for off-road vehicles. Background Technology
[0002] In the automotive market, off-road SUVs and pickup trucks are becoming increasingly personalized in their appearance. As an important part of the exterior decoration, wheel arches are also becoming wider, larger, and heavier in line with the styling. Wheel arches are installed in conjunction with many other body parts, such as bumpers, fenders, side panels, and underbody mounting brackets. They also need to be designed to fit the front bumper assembly for disassembly and repair, while meeting the overall vehicle exterior clearance requirements. This places high demands on wheel arch design and development technology. If the wheel arch structure design is not properly considered, it will directly lead to defects such as misfitting of the overall vehicle exterior clearance, product deformation, and lifting, which will seriously affect the overall appearance quality of the vehicle and the user's experience.
[0003] Currently, for wheel arches on off-road vehicles, common existing technologies include: 1. Single-fit snap-fit connection structure, which suffers from problems such as large assembly gaps and difficulty in controlling deformation and warping; 2. Inner and outer panel welded structure, which has relatively high mold and unit costs, and excessive investment in welding tooling; 3. Exposed bolt fastening structure, which results in multiple exposed bolt heads, affecting aesthetics. Furthermore, existing wheel arch structures suffer from uneven installation point distribution, weak design, large gaps in overall vehicle dimensions after assembly, gaps, poor fit, warping, and unsightly exposed bolts. To address these issues, this invention provides a double-layer wheel arch structure for off-road vehicles. Utility Model Content

[0010] Preferably, the inner plate of the wheel arch has an array of inner plate recesses, and the inner plate recesses are provided with a second insertion hole, and the fixing bolt is inserted into the second insertion hole.
[0011] The technical effects and advantages of this utility model are as follows: This type of off-road vehicle features a double-layer wheel arch structure. By using a double-layer design and quick connection via bolts between the inner wheel arch and fender, and by sliding snaps between the outer wheel arch and fender, and between the outer and inner wheel arches, the installation points are evenly distributed, resulting in a complete and seamless connection without any local warping. After assembly, there are minimal gaps, no leaks, and a perfect fit. Furthermore, the bolted connection provides a robust structure suitable for off-road use, and the bolts are not exposed. Finally, this double-layer wheel arch is simple to assemble and easy to replace; generally, only the outer wheel arch needs to be replaced. Attached Figure Description
