[0061] Preferably, a universal wheel fixing flange 42 is provided inside the bottom plate reinforcing frame 41, and the universal wheel is fixed inside the universal wheel fixing flange 42.

[0062] Preferably, the bottom plate 4 is provided with a bottom plate flange 43 which cooperates with the stacking fixing hole 351.

[0063] As Figures 1 - 2 shown, the energy storage module 1 is fixed inside the module frame 3 to form an energy storage stacking structure. The energy storage stacking structure can be stacked up and down according to the required quantity. The cover plate 2 is installed on the uppermost side, and the bottom plate 4 is installed on the lowermost side. A bottom plate reinforcing frame 41 is provided on the lower side of the bottom plate 4. A universal wheel fixing flange 42 is provided inside the bottom plate reinforcing frame 41. A universal wheel is provided on the lower side of the universal wheel fixing flange 42, and the universal wheel is not shown in the figure. When the universal wheel is not provided, the energy storage cabinet can be fixedly placed. The bottom plate reinforcing frame 41 has a structure similar to a well shape, so that the force is more uniform and the structural stability is improved.

[0064] As Figures 3 - 5 shown, the side guard plates 35, the upper guide rails 33, and the lower guide rails 34 are symmetrically arranged left and right, and the upper cross beam 31 and the lower cross beam 32 are symmetrically arranged front and back. Multiple energy storage stacking structures are stacked up and down, and the stacking flange plates 311 are connected to the corresponding stacking fixing holes 351 above them by screws. For the module frame 3 of the uppermost energy storage stacking structure, the stacking flange plate 311 is connected to the cover plate fixing hole 21 by screws. For the module frame 3 of the lowermost energy storage stacking structure, the stacking fixing hole 351 is connected to the bottom plate flange 43 by screws.

[0065] As Figures 5 - 6 shown, module handles 12 and module flange plates 11 are provided on both sides of the front side of the energy storage module 1. Fixing holes are provided on both the upper and lower sides of the module flange plate 11, and they are connected to the corresponding module fixing holes 352 by screws. The module flange plate 11 has an L-shaped structure.

[0066] As shown in FIGS. 7-8, side guard plate reinforcing flanges 353 are provided on both the upper and lower sides of the side guard plate 35. Upper flanging limiting walls 354 are formed on the left and right end faces of the upper side guard plate reinforcing flange 353. An upper flanging limiting step 355 is formed on the unflanged end face on the upper side of the side guard plate 35. In order to Figure 5Taking the direction as a reference, lower flanging limiting steps 356 are provided on both the front and rear sides of the side guard plate 35. The lower flanging limiting steps 356 are formed by inwards flanging the front and rear sides of the side guard plate 35 and then downwards flanging from top to bottom, which improves the structural strength. The front and rear widths of the upper crossbeam upper flanging 312 and the upper crossbeam lower flanging 313 are the same, and in cooperation with Figure 5 It can be seen that the lateral cross-section of the upper crossbeam 31 is in a U-shaped structure, which improves the structural strength. Arc-shaped extension parts are provided on both sides of the upper crossbeam upper flanging 312, and the stacking flange 311 is arranged on the arc-shaped extension parts. The end surface of the upper flanging limiting step 355 extending downwards towards the inner side of the upper crossbeam 31 is the auxiliary limiting end surface. Another example is Figures 4 - 5 As shown, for the symmetrical upper crossbeam 31, between the arc-shaped extension parts is the side guard plate strengthening flanging 353, which is in contact and limited with the upper flanging limiting wall 354. The material thickness of the upper crossbeam upper flanging 312 and the arc-shaped extension parts is the same as that of the side guard plate strengthening flanging 353, so that a unified plane is formed after the two are spliced, which is more airtight and improves the structural stability during stacking. The upper crossbeam lower flanging 313 is placed on the lower flanging limiting step 356, and the lower flanging limiting step 356 is used to limit and support the upper crossbeam lower flanging 313. The auxiliary limiting end surface of the upper flanging limiting step 355 further contacts and limits the upper crossbeam lower flanging 313, improving the structural stability.

[0067] Such as Figures 9 - 10 As shown, the lower crossbeam 32 is in a U-shaped structure, and the lower guide rail 34 is in an L-shaped structure.

[0068] Such as Figure 11 As shown, on the front and rear sides of the upper guide rail 33, lower flanging connection steps 331 extend upwards and outwards. Another example is Figure 5 、 8 As shown, the front and rear sides of the upper guide rail 33 are welded and connected to the upper crossbeam lower flanging 313 through the lower flanging connection steps 331. The lower flanging connection steps 331 make the middle part of the upper guide rail 33 flush with the plane where the upper crossbeam lower flanging 313 is located, which is more conducive to the guiding effect of the upper guide rail 33.

[0069] Such as Figure 12 As shown, on the upper side of the bottom plate 4, a bottom plate flange 43 is provided, which is connected to the stacking fixing hole 351 by screws.

[0070] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made within the scope of the patent application of the present invention shall fall within the scope covered by the present invention.
