The above structure proposes an improved technical solution in view of the deficiencies in the prior art. When the structure is set up, a split structure is no longer adopted, and there is no need to process the sheet metal and convex weld nuts first, and then weld them. Instead, an integrated stamping process is directly used instead of nut convex welding to form an integrated structure. Specifically, the sheet metal raw material is stamped to form an integrated reinforcing plate structure, and the reinforcing plate structure comprises the reinforcing plate body 1, the reinforcing plate nut 2, and the reinforcing plate reinforcement 3, and the above components are an integrated structure.
