It should be understood that the first bending structure and the second bending structure are illustrated in fig. 2 for convenience of illustration, and a gap is left between the first bending structure and the second bending structure, but when actually connected, the first bending structure 11 and the second bending structure 21 should be attached, and other adjacent structures in fig. 2 are processed in a similar manner. Fig. 2 is a schematic view showing the connection between the top plate 10 and one side plate 20, and the connection between the top plate 10 and the other side plate 20 is also performed in the same manner.

During assembly, the first bending structure 11 is overlapped on the step surface, and the first bending structure 11 is in sealing connection with the step surface, so that sealing between the top plate 10 and the side plate 20 is realized, and further sealing of the top plate 10 is realized.

For the convenience of understanding the cooperation between the first bending structure and the second bending structure provided in the embodiments of the present application, a detailed description thereof will be provided below with reference to fig. 3 and 4.

Referring first to fig. 3, fig. 3 shows a schematic view of the structure of the top plate. The first bending formation 11 is located at the end of the top panel and the third bending formation 12 is located on the side of the top panel 10 adjacent the end. I.e. the first 11 and third 12 bending structures are located on adjacent sides of the top panel 10. The first bending structure is an overlapping structure applied when the top plate 10 is connected with the left side plate or the right side plate, and is positioned at the end part, close to the left side plate and the right side plate, of the top plate 10; the third bending structure 12 is also a structure in which the top plate 10 is overlapped with the left side plate or the right side plate, and is located on one side of the top plate 10 close to the rear side plate or the cabinet door.

When the bending device is arranged, the first bending structure 11 and the third bending structure 12 are integrated with the top plate, that is, the plate material is bent by the bending device to form the top plate and the first bending structure 11 and the third bending structure 12.

The first bending structure 11 may adopt different bending modes when bending specifically. Illustratively, the first bending structure 11 is an L-shaped bending structure, and the first bending structure 11 includes a first vertical portion 111 connected to the top plate and a first horizontal portion 112 connected to the first vertical portion 111, wherein the bending direction of the first vertical portion 111 faces the inside of the cabinet, and the bending direction of the first horizontal portion 112 faces a direction away from the side plate, so that the end of the top plate forms a "]" -shaped bending structure. In cooperation with the second bending structure 21, the first horizontal portion 112 may overlap the step surface of the second bending structure 21.

As an alternative, when the first bending structure 11 is provided, the length of the first bending structure 11 is smaller than that of the side thereof, so that a notch is formed at the end of the side for matching with the hoisting structure. Illustratively, the length of the first bending structure is L1, and the length of the side thereof is L2, so that: l1 < L2. The length of each notch is (L2-L1)/2.

It should be understood that the first bending structure 11 provided in the embodiments of the present application may also be formed by other modified bending structures besides the aforementioned "L" shaped bending structure, for example, the included angle between the first vertical portion 111 and the top plate is an acute angle or an obtuse angle, and the first horizontal portion 112 is parallel to the top plate, and the modified structures can be applied in the embodiments of the present application.

The third bending structure 12 is formed by bending the top plate 10 into the energy storage cabinet for multiple times when the energy storage cabinet is specifically bent. Illustratively, the third bending structure 12 includes a sixth vertical portion 121 connected to a side edge of the top plate 10 and bent toward the inside of the energy storage cabinet, a fourth horizontal portion 122 connected to the sixth vertical portion 121 and bent toward the inside of the energy storage cabinet, a seventh vertical portion 123 connected to the fourth horizontal portion 122 and bent toward the inside of the energy storage cabinet, and a fifth horizontal portion 124 connected to the seventh vertical portion 123 and bent toward the outside of the energy storage cabinet. In the specific bending process, the top plate 10 is bent downward (toward the bottom plate) to form a sixth vertical portion 121, then bent again toward the inside of the energy storage cabinet to form a fourth horizontal portion 122, bent again downward to form a seventh vertical portion 123, and then bent outward of the energy storage cabinet to form a fifth horizontal portion 124.

When the third bending structure 12 is specifically provided, the length of the third bending structure 12 is smaller than the length of the top plate. That is, the overall length of the third bending structure 12 is smaller than the length of the side where the third bending structure is located, so that a notch is formed at the end of the side to be matched with the hoisting structure. Illustratively, the length of the third bending structure 12 is L3, and the length of the side edge thereof is L4, so that L3 < L4 is satisfied.

The third bending structure 12 passes through the fifth horizontal portion 124 to overlap the fourth bending structure when overlapping the fourth bending structure.

Referring to fig. 4, fig. 4 shows a structural schematic view of the side panel. The second bending structure 21 is located at the end of the side plate close to the top plate, and the fourth bending structure 22 is located at the side of the side plate 20 adjacent to the end. I.e. the second bending structures 21 and the fourth bending structures 22 are located at adjacent sides of the side plate 20. The first bending structure is an overlapping structure applied when the side plate 20 is overlapped with the top plate, and is positioned at the end part of the side plate 20 close to the top plate; the fourth bending structure 22 is also a structure formed by overlapping the side plate 20 and the top plate, and taking the left side plate as an example, the fourth bending structure 22 is located at a side close to the rear side plate or the cabinet door.

When the plate bending device is arranged, the second bending structure 21 and the fourth bending structure 22 are integrated with the side plate, that is, the plate is bent by the bending device to form the side plate, the second bending structure 21 and the fourth bending structure 22.

The second bending structure 21 may adopt different bending modes when bending specifically. Illustratively, the second bending structure 21 is a Z-shaped bending structure, and the second bending structure 21 includes a second horizontal portion 213 connected to the side plate, a second vertical portion 212 connected to the second horizontal portion 213, and a third horizontal portion 211 connected to the second vertical portion 212. Specifically, when the second horizontal portion 213 is bent, the bending direction thereof is bent in a direction close to the top plate, the second horizontal portion 213 is bent in a downward direction, and the third horizontal portion 211 is bent in a direction close to the top plate, so that the second bending structure 21 forms a step structure, and the step surface is located on the third horizontal portion 211, and the step surface is a surface of the third horizontal portion 211 facing the first horizontal portion.

As an alternative, when the second bending structure 21 is provided, the length of the second bending structure 21 is smaller than that of the side thereof, so that a notch is formed at the end of the side for matching with the hoisting structure. Illustratively, the length of the second bending structure 21 is L5, and the length of the side thereof is L6, then: l5 < L6. The length of each notch is (L6-L5)/2.

It should be understood that the second bending structure 21 is formed to have a structure matched with the shape of the first bending structure 11, and when the shape of the first bending structure 11 is changed, the corresponding second bending structure 21 may also be changed accordingly, so as to ensure that the second bending structure 21 can support the first bending structure 11.

When the top plate is overlapped on the side plate, the first horizontal portion 112 abuts on the third horizontal portion 211, and the first bending structure 11 and the second bending structure 21 are fixedly connected by welding, and meanwhile, the sealing connection is also realized. As an optional scheme, when the first bending structure 11 overlaps the second bending structure 21, the first vertical portion 111 abuts against and is attached to the second vertical portion 212, so that the phenomenon that the appearance of the energy storage cabinet is affected due to an excessively large gap between the top plate and the side plate is avoided.

When the fourth bending structure 22 is specifically bent, the side edge of the side plate 20 is bent multiple times towards the inside of the energy storage cabinet, and because the side edge is a vertical side edge, the formed fourth bending structure 22 has multiple vertical portions. Illustratively, the fourth bending structure 22 is a zigzag structure, and the fourth bending structure 22 includes a third vertical portion 221 connected to a side edge of the side plate and bending toward the inside of the energy storage cabinet, and a fourth vertical portion 222 connected to the third vertical portion 221; wherein the fourth vertical portion 222 overlaps the third bending structure. During the specific bending, the vertical side edge of the side plate 20 is bent towards the inside of the energy storage cabinet to form a third vertical portion 221, and then is bent towards the inside of the energy storage cabinet again to form a fourth vertical portion 222, and is bent again to form a fifth vertical portion 223.

When the fourth bending structure 22 is overlapped with the third bending structure, the fifth vertical portion 223 is overlapped with the third bending structure, specifically, the fifth vertical portion 223 is overlapped with the fifth horizontal portion.

When the fifth upright portion 223 is specifically provided, the length of the fourth upright portion 222 is smaller than the length of the fourth upright portion 222. So that it is not necessary to form the fifth vertical portion 223 to be too long, and it is sufficient to form only the fifth vertical portion 223 at one end near the top plate to overlap the fifth horizontal portion.

It can be seen from the above description that, when the top plate is matched with the side plate, the bending structures (the first bending structure to the fourth bending structure) are respectively arranged on the top plate 10 and the side plate 20, and the top plate 10 and the side plate 20 are matched with each other through the bending structures to realize connection, so that the strength of the connection structure between the top plate and the side plate is enhanced, the structural strength of the energy storage cabinet is improved, the stability of the energy storage cabinet is improved, and the service life of the energy storage cabinet is also prolonged.
