A box-shaped structure capable of placing a plurality of energy storage batteries 4 is formed by enclosing between the module bottom plate 1, the module baffle 2, and the module cover plate 3; wherein, limiting parts 101 are arranged at both ends of the edge of the module bottom plate 1 and are bent inwards to abut against the module baffle 2, and a module pressing plate 5 capable of pressing the module cover plate 3 against the top side of the energy storage battery 4 is arranged on the module baffle 2.

[0026] Specifically, the module baffle 2 is abutted against the upper limit portion 101 of the module bottom plate 1, and the module bottom plate 1 and the module baffle 2 can be detachably connected by bolts. The limit baffle is supported at the openings at both ends of the module bottom plate 1, connecting the two sides of the module bottom plate 1, and serving as the skeleton of the box-type structure. The limit portion 101 is a bent portion of the edge of the module bottom plate 1, which can limit and locate the position of the module baffle 2 on the module bottom plate 1, and the limit portion 101 is integrally formed with the module bottom plate 1 to ensure the strength of the connection between the module baffle 2 and the module bottom plate 1. A box-shaped structure with an opening at the top is formed between the module bottom plate 1 and the module baffle 2. Several energy storage batteries 4 can be placed in the box-shaped structure in sequence. After the module cover plate 3 blocks the opening of the box-shaped structure, the module cover plate 3 can be pressed down on the energy storage battery 4 by overlapping the two ends of the module pressure plate 5 on the two module baffles 2 and fastening the module baffles 2 with bolts, so as to limit and fix the position of the energy storage battery 4 in the box-shaped structure. The energy storage battery module structure in the present technical solution has an overall frame consisting only of the module bottom plate 1, the module baffle 2, the module cover plate 3 and the module pressure plate 5. The structure is simple and beautiful, with high space utilization, and can be fastened and disassembled by bolts. The structure is simple and has good stability. At the same time, the energy storage battery module structure and the energy storage battery module structure can also be quickly disassembled and connected by fasteners such as bolts, which is convenient for stacking multiple energy storage battery module structures and increasing the storage capacity to adapt to a variety of application environments.

[0027] The above, such as Figure 2 As shown, the module cover plate 3 is covered on a plurality of energy storage batteries 4, and the edge of the module cover plate 3 is provided with a folded edge 301 that is folded outward and can be abutted against the energy storage battery 4, and the module pressing plate 5 is pressed on the folded edge 301, so that the module pressing plate 5 fixes the position of the energy storage battery 4 in the box-shaped structure through the module cover plate 3. A gap is provided between the module cover plate 3 and the positive and negative electrodes on the energy storage battery 4 to reserve the wiring position of the energy storage battery 4, and at the same time, the positive and negative electrodes on the energy storage battery 4 are exposed for heat dissipation.

[0030] Furthermore, elastic insulating sheets 11 are provided between the module baffle 2 and the energy storage battery 4, and between the energy storage batteries 4 and the energy storage batteries 4. The elastic insulating sheets 11 are used to isolate the energy storage batteries 4 and the module baffle 2, which not only plays the role of insulation and shock absorption, but also can compensate for the dimensional deviation caused by the superposition of the thickness tolerance of the energy storage battery 4, thereby increasing the overall safety of the module.

[0031] Furthermore, both sides of the module bottom plate 1 are provided with recessed portions 102 that can be abutted against the energy storage battery 4, and the gaps between the two sides of the module bottom plate 1 and the energy storage battery 4 are filled with thermal conductive silicone, so that when the temperature of the energy storage battery 4 rises, the heat can be quickly transferred to the module bottom shell for heat dissipation.

[0032] In the present technical solution, the module bottom plate 1 is an integrally formed sheet metal structure and can be made of aluminum material. The overall module bottom shell is made of aluminum material and has high rigidity. During installation, it forms a structure that supports and protects the energy storage battery 4 with the module baffle 2, the module cover 3 and the module pressure plate 5. The structure has higher stability and strength and can reduce deformation inside the energy storage battery 4. Embodiment 2

[0035] Working principle: The module baffle 2 is supported in the U-shaped module bottom shell as the skeleton of the module bottom shell. A box-type structure with an open top is formed between the module bottom plate 1 and the module baffle 2. Several energy storage batteries 4 can be placed in the box-type structure in sequence. After the module cover 3 blocks the opening of the box-type structure, the two ends of the module pressure plate 5 are overlapped on the two module baffles 2 and fastened with the module baffles 2 by bolts. Then, the module cover 3 can be pressed down on the energy storage battery 4 to limit and fix the position of the energy storage battery 4 in the box-type structure. The overall frame is composed of only the module bottom plate 1, the module baffle 2, the module cover 3 and the module pressure plate 5. The structure is simple and beautiful, the space utilization rate is high, and it can be fastened and disassembled by bolts. The structure is simple and the stability is good.

[0036] At the same time, the energy storage battery module structures can be stacked and fixed with each other, and the series and parallel connection of the energy storage battery module structures can be achieved by connecting the copper busbars 13, and then the whole structure can be installed in the energy storage device. There is no need for a layered design of the main chassis of the energy storage device, which can simplify the structure of the main chassis, reduce weight, and meet the needs of large energy storage capacity.
