The cross-section of the reinforcement cavity is crescent-shaped, which further ensures the structural strength of the reinforcement plate and enhances the strength and rigidity of the front floor.

In the above-mentioned one-piece reinforcing plate structure of the central tunnel of the automobile, several beam mounting holes are opened on the reinforcing plate body. By setting the beam installation holes, the reinforcement plate is provided with beams, which further ensures the structural strength of the reinforcement plate and enhances the strength and rigidity of the front floor.

In the above-mentioned one-piece reinforcing plate structure of the central tunnel of the automobile, several positioning holes are opened on the reinforcing plate body. The design of the positioning hole can meet the needs of actual production welding positioning with only one set of fixtures, which solves the problems of inconvenient positioning of mutually independent reinforcing plates and high positioning operation costs.

Compared with the prior art, the integrated reinforced plate structure of the central passage of the automobile has the following advantages: 1. Compared with the conventional independent reinforced plate, the strength is better, and there is a larger overlapping area with the middle section of the central passage, which can be well The lateral energy received can be transmitted to avoid stress concentration, and it also effectively solves the problem that the independent reinforced plate is easy to be torn during use. 2. The gap between the surface of the reinforcement part and the inner wall of the central channel forms a reinforcement chamber, which is better in strength and rigidity than existing independent reinforcement plates. 3. On the basis of ensuring the structural function, through the reasonable arrangement of reinforcing ribs, beam installation holes, positioning holes and other structural designs, only one set of fixtures can be used to meet the needs of actual production welding positioning, and solve the problem of mutually independent reinforcing plates The positioning is inconvenient and the positioning operation cost is high.
