[0028] The main body of the cover plate 1 has an arc-shaped structure and is a one-piece molded structure made of 6063T5 aluminum alloy. The arc-shaped design of the main body of the cover plate 1 conforms to the vehicle's exterior curves, enhancing overall harmony. Made of 6063T5 aluminum alloy in a one-piece molding process, the arc-shaped structure meets vehicle aerodynamic requirements, reducing wind resistance and noise during driving. The 6063T5 material of the main body of the cover plate 1 possesses high strength, good corrosion resistance, and machinability. The one-piece molding process avoids seams, ensuring overall structural rigidity and preventing deformation over long-term use.

[0029] The role and effect of the embodiments

[0030] The main body of the cover plate 1 is made of 6063T5 aluminum alloy in an integral arc design, which can effectively protect related parts, adapt to the vehicle's exterior curves, meet aerodynamic requirements to reduce wind resistance and noise, and also has high strength, corrosion resistance and overall rigidity, and is not easily deformed after long-term use. The fixing bracket 2 is connected to the main body of the cover plate 1 and the vehicle body by bolts through the bent bracket plate 201. The bolt heads are external for easy removal of the fixing during maintenance.
