[0041] In this way, the frame is split into three independent modules, namely the frame body 1, the front axle mounting assembly 2 and the rear axle mounting assembly 3, through split modular design. After each module is processed and manufactured separately, it is assembled as a whole. This can greatly shorten the processing cycle, improve production efficiency, simplify the processing technology, and improve product quality. Moreover, the modular design can quickly realize mass production, and is easy to maintain, and it is easy to expand and iterate products. This solves the problems of the traditional frame processing cycle being long, the production efficiency being low, the welding deformation being large, and the difficulty in controlling the dimensional accuracy.

[0042] In the embodiment of the present utility model, Figure 2 As shown, the frame body 1 includes a pair of side panels 11 arranged at intervals, and a first vertical panel 12, a second vertical panel 13 and a third vertical panel 14 arranged at intervals in sequence from the first end to the second end of the side panel 11, that is, from front to back.

In this way, the main part of the frame is formed by a pair of side panels 11 and a plurality of middle vertical panels, which is similar to a cage-type structure, has a strong load-bearing capacity and is easy to process. In addition, for vehicle bodies of similar meter segments, the product can be quickly built by increasing the width of the middle vertical panel, so that products of similar meter segments can be borrowed from each other, and the degree of commonality is high. It should be noted that, with the following configuration, Figure 2 As for the placement position of the frame shown in the figure, the direction indicated by the solid arrow in the figure is the front-rear direction, the direction indicated by the hollow arrow in the figure is the width direction, the left end in the figure is the first end of the side panel 11, and the right end in the figure is the second end of the side panel 11.

[0043] Furthermore, in the embodiment of the utility model, the frame body 1 further includes a turntable mounting plate 15, and the turntable mounting plate 15 is disposed on the top of the pair of side plates 11.

In this way, the groove-shaped reinforcement plates 24 are connected to the side plates 11 of the frame body 1, which can further strengthen the lateral strength of the front axle assembly, avoid cracking, breaking and the like, and effectively improve the overall performance of the frame.

[0048] In the embodiment of the utility model, the rear axle mounting assembly 3 includes a bending plate 31, a pair of fixing plates 32, and a reinforcing connecting plate. Figure 1 As shown, the bending plate 31 is connected to the frame body 1. Specifically, the bending plate 31 is designed as a U-shaped bending plate and is fixedly connected to the second ends of a pair of side plates 11. Figure 4 As shown, a pair of fixing plates 32 are arranged at both ends of the bending plate 31, and the fixing plates 32 are used to fix and install devices such as the travel reducer and the rear wheel. In addition, the pair of fixing plates 32 and the bending plate 31 together enclose a cavity structure with an opening. The reinforcing connecting plate is arranged on the opening side of the cavity structure, and the reinforcing connecting plate is connected to both the bending plate 31 and the fixing plate 32. Specifically, the reinforcing connecting plate includes a first reinforcing connecting plate 33 and a pair of second reinforcing connecting plates 34.
