[0031] On the basis of the above structure, front seat rear mounting beams 3 are respectively arranged on the left front floor 12 and the right front floor 13. The two front seat rear mounting beams 3 are symmetrically arranged on both sides of the front floor center channel 11, so as to support the rear parts of the seats of the main driver and the co-driver. At the same time, a front seat front mounting beam 8 is also arranged in parallel on the front side of the front seat rear mounting beam 3, and the front seat front mounting beams 8 and the front seat rear mounting beams 3 corresponding to each other are used to reliably support the same seat.

[0032] In order to ensure the structural stability of the left front floor 12 and the right front floor 13 in the rear area of ​​the seat, a floor reinforcement plate 4 is respectively provided above the two. The two floor reinforcement plates 4 can respectively strengthen the structures of the corresponding parts of the left front floor 12 and the right front floor 13, thereby improving the overall structural strength and rigidity of the front floor.

[0033] In some embodiments, the left front floor 12 and the right front floor 13 may be configured as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The left front floor 12 and the right front floor 13 are respectively provided with a reinforcing rib group 5 protruding upward, and the reinforcing rib group 5 includes a longitudinal rib 51 arranged along the X direction of the vehicle body and a transverse rib 52 arranged along the Y direction of the vehicle body.

[0035] Specifically, the reinforcing rib group 5 includes longitudinal ribs 51 extending along the X direction of the vehicle body and transverse ribs 52 extending along the Y direction of the vehicle body. The longitudinal ribs 51 and the transverse ribs 52 can form a criss-cross reinforcing structure. The two can adopt different forms of mutual intersection or mutual separation, and both can achieve effective structural reinforcement effects.

[0036] In some possible implementations, the above-mentioned characteristic floor reinforcement plate 4 is adopted as follows Figure 1 , Figure 2 and Figure 4 See the structure shown. Figure 1 , Figure 2 and Figure 4 The floor reinforcement plate 4 includes a transverse reinforcement portion 41 extending along the Y direction of the vehicle body and a longitudinal reinforcement portion 42 extending along the X direction of the vehicle body.

[0037] In this embodiment, the floor reinforcement plate 4 is in the form of a combination of a transverse reinforcement part 41 and a longitudinal reinforcement part 42, and the transverse reinforcement part 41 and the longitudinal reinforcement part 42 form a structure approximately in the shape of a T. The above design form is obtained through topological analysis. After simulation analysis, the above T-shaped structure is compared with the existing rectangular reinforcement structure, and the weight of a worker is also simulated to step on this position. Although the difference in the deformation caused by stepping on the two is not large, the T-shaped structure can achieve a lightweight design effect of 56% weight reduction, and can accurately strengthen the weak position of the left front floor 12 or the right front floor 13 to meet the stepping stiffness requirements, ensuring that the stepping stiffness meets the performance requirements while also achieving a lightweight design of the structure.

The overlapping reinforcement ribs 32 are arranged to protrude upward, and the area between two adjacent overlapping reinforcement ribs 32 is connected to the floor reinforcement plate 4. The overlapping reinforcement ribs 32 have a good structural reinforcement effect, thereby ensuring the structural strength of the overlapping portion and avoiding structural deformation of the area due to force.

[0041] In some embodiments, the above-mentioned characteristic longitudinal reinforcement portion 42 can be adopted as follows Figure 1 , Figure 2 and Figure 6 See the structure shown.

[0042] In this embodiment, in the vehicle body Y direction, the longitudinal reinforcement part 42 is overlapped at the position where the two transverse ribs 52 are disconnected, which can play a role in structural compensation and structural reinforcement. The welding boss 43 provided on the longitudinal reinforcement part 42 can not only serve as structural reinforcement, but also be welded to the top surface of the front floor body 1 through the bottom surface. The welding boss 43 can be in different shapes such as strips or blocks. Specifically, the welding boss 43 can be extended along the vehicle body Y direction, which is convenient for structural connection and reinforcement of the transverse ribs 52 disconnected on both sides.
