[0037] In order to improve the accessibility of the cab and increase the cab space, the cab of the entire commercial vehicle is raised, and the floor structure is also raised, so there is no need to set a bulge on the floor structure, that is, the bulge on the original floor structure is eliminated. Figure 2 and Figure 4 As shown, the left floor assembly 3 and the right floor assembly 4 are symmetrically arranged at the left and right ends of the middle floor assembly 2, the middle floor middle plate assembly 22 and the middle floor rear plate assembly 23 in the middle floor assembly 2 are flat floor structures, and the left floor assembly 3 and the right floor assembly 4 are at the same height as the middle floor middle plate assembly 22 and the middle floor rear plate assembly 23 on the horizontal plane.

[0038] The above-mentioned commercial vehicle floor structure eliminates the bulge in the original floor structure, thereby realizing a nearly flat floor structure, improving the passability of the cab and increasing the space of the cab, thereby meeting the requirements of the driver and passengers for spacious and comfortable cab space. Moreover, the entire commercial vehicle floor structure is constructed in a block-by-block manner, so that the length of the middle floor rear plate assembly 23, the left floor rear plate assembly 32 and the right floor rear plate assembly 42 can be adjusted according to the cab length requirements to meet the cab space expansion requirements in the length direction. The front floor beam assembly 1, the middle floor front plate 21, the middle floor middle plate assembly 22, the left floor front plate assembly 31 and the right floor front plate assembly 41 remain unchanged before and after the expansion, greatly reducing the number of molds; and the width of the middle floor assembly 2 can be adjusted according to the cab width requirements to meet the cab space expansion requirements in the width direction.

[0039] Specifically, refer to Figure 4 As shown, two overlapping edges spaced apart from each other are provided at both ends of the middle floor assembly 2, and a concave reinforcing rib groove is formed between the two overlapping edges. The left floor assembly 3 is overlapped on the two overlapping edges at the left end of the middle floor assembly 2 and spot welded on the overlapping edges to weld the left floor assembly 3 to the middle floor assembly 2.

[0040] Similarly, the right floor assembly 4 is overlapped on two overlapping edges at the right end of the middle floor assembly 2 and spot welded on the overlapping edges to weld the right floor assembly 4 to the middle floor assembly 2 .

[0041] More specifically, the width between the two overlapping edges set at the left end of the middle floor assembly 2 and the width of the two overlapping edges set at the right end of the middle floor assembly 2 are both 20 mm, the welding points are evenly distributed along the B direction on the overlapping edges, and the spacing between adjacent welding points does not exceed 60 mm and is not less than 20 mm.

[0042] refer to Figure 5 and Figure 6 As shown, the center floor front plate 21, the center floor middle plate assembly 22 and the center floor rear plate assembly 23 of the center floor assembly 2 are overlapped in order from front to back and from low to high, and the overlap edge widths of the center floor front plate 21 and the center floor middle plate assembly 22 and the overlap edge widths of the center floor middle plate assembly 22 and the center floor rear plate assembly 23 are both not less than 20 mm and not more than 30 mm.

The welding points are evenly distributed, and the interval between two adjacent welding points does not exceed 60 mm and is not less than 20 mm.

[0044] Similarly, the right floor rear panel assembly 42 of the right floor assembly 4 is overlapped on the right floor front panel assembly 41 and connected by spot welding, which will not be described in detail here.

[0045] refer to Figure 5 and Figure 6 As shown, in order to improve the structural strength of the entire commercial vehicle floor structure, the middle floor middle plate assembly 22 includes a middle floor middle plate 221, a speed control mechanism reinforcement plate 222, and a middle floor middle reinforcement plate 223. The middle floor middle plate 221, as the main structure of the middle floor middle plate assembly 22, is connected to the middle floor front plate 21, and the speed control mechanism reinforcement plate 222 and the middle floor middle reinforcement plate 223 are welded to the lower surface of the middle floor middle plate 221 in sequence along the front and rear directions, and the front and rear ends of the speed control mechanism reinforcement plate 222 are both concave to form grooves, and the speed control mechanism reinforcement plate 222 corresponds to the position of the middle floor middle plate 221 where the speed control mechanism needs to be installed.

[0046] Continue to refer Figure 5 and Figure 6 As shown, the center floor rear panel assembly 23 includes a center floor rear panel 231 and a center floor rear reinforcement panel 232. The center floor rear panel 231 is connected to the center floor center panel 221 as the main structure of the center floor rear panel assembly 23. Two center floor rear reinforcement panels 232 are provided. The two center floor rear reinforcement panels 232 are spaced apart along the front-to-rear direction on the lower surface of the center floor rear panel 231. The center floor rear reinforcement panels 232 both adopt a U-shaped groove structure, and the front and rear ends thereof are bent to form overlapping edges.

The left floor front panel 311 is connected to the middle floor middle panel assembly 22 as the main structure of the left floor front panel assembly 31. The left front seat reinforcement panel 312 and the left rear seat reinforcement panel 313 are welded to the lower surface of the left floor front panel 311 in sequence along the front-to-back direction. The left front seat reinforcement panel 312 is convex to form an overlapping edge, and the left rear seat reinforcement panel 312 is arranged as a U-shaped groove structure, and its left and right ends are bent to form overlapping edges.

[0048] The left floor rear panel assembly 32 includes a left floor rear panel 321 and a left floor rear reinforcement panel 322.

[0050] The above reinforcement plate structure can meet the requirements of bending and torsional rigidity, pedaling rigidity and seat mounting point strength of the floor structure of commercial vehicles. It is understandable that the number of reinforcement plates on each floor assembly can be further increased according to the structural strength requirements. For example, when the length of the left floor rear plate 321 is extended, the number of the left floor rear reinforcement plates 322 can be adaptively increased.

[0051] In this embodiment, the main structures of the above-mentioned floor assemblies are all made of cold-rolled steel plates, among which the middle floor front plate 21, the middle floor middle plate 221 and the middle floor rear plate 231 in the middle floor assembly 2 are 1.0 mm thick, the left floor front plate 311 and the right floor front plate are 1.8 mm thick, and the main structures of the remaining floor assemblies and the reinforcing plates are made of 1.5 mm thick plates.
