Technical Field
[0001] This invention relates to the field of energy storage battery technology, specifically to a modularly assembled energy storage battery module. Background Technology
[0002] With the rapid development of the new energy industry, energy storage battery modules, as core components for energy storage and supply, are widely used in various scenarios such as residential energy storage, industrial and commercial energy storage, and grid energy storage. Modular assembly, due to its advantages such as high assembly efficiency, convenient maintenance, and flexible capacity expansion, has become the mainstream design direction for energy storage battery modules. In existing technologies, modular energy storage battery modules typically employ a dense arrangement of multiple cells. To achieve electrical isolation between adjacent cells and between cells and the casing, and to prevent safety hazards such as short circuits and leakage caused by direct contact between cells and the casing, insulating pads are usually placed between adjacent cells and between cells and the casing. However, because only insulating pads are placed between adjacent cells, and the cells are densely arranged, the heat generated between adjacent cells cannot be effectively dissipated and will accumulate between the cells. This leads to a continuous increase in the internal temperature of the energy storage battery, resulting in ineffective heat dissipation, which shortens the lifespan of the cells and may also cause safety risks such as cell bulging and thermal runaway. Summary of the Invention

[0021] The transmission mechanism includes a threaded rod 22 and a limiting rod 23.

The end of the spiral transmission frame 24 away from the threaded rod 22 is slidably sleeved on the outside of the limiting rod 23. The two ends of the spiral transmission frame 24 respectively cooperate with the two ends of the translation bracket 14. The top of the translation bracket 14 is fixedly installed with multiple evenly distributed trapezoidal blocks 25. The two sides of the multiple trapezoidal blocks 25 respectively cooperate with one end of their respective translation brackets 19.
[0022] The top of the U-shaped frame 8 has mounting slots 27 at both ends. The top of the hollow bracket 9 has mounting blocks 28 at both ends. The two mounting blocks 28 cooperate with their respective mounting slots 27. The top of the hollow bracket 9 and the top of the U-shaped frame 8 have multiple evenly distributed mounting slots 29. The top of the multiple hollow brackets 10 has mounting blocks 30 at both ends. The multiple mounting blocks 30 cooperate with the multiple mounting slots 29.
[0023] Two positioning holes 31 are opened at both ends of the bottom of the two mounting blocks 28. Positioning rods 32 are provided inside the multiple positioning holes 31. The side of the multiple positioning rods 32 away from their respective positioning holes 31 is fixedly connected to the loop transmission frame 24. One end of the multiple mounting blocks 30 is provided with a positioning groove 33.

[0024] A groove 35 is provided at one end of the top of the hollow bracket 19 and at one end of the top of the multiple hollow brackets 20. A toggle block 26 is provided inside the multiple grooves 35. The bottom of the multiple toggle blocks 26 is fixedly connected to their respective sliding brackets 13 and sliding brackets 28.
[0025] Working principle: When in use, first place an insulating pad 11 at the bottom of the mounting groove 7, then place an insulating pad 11 on each of the four walls of the mounting groove 7. Next, insert the mounting blocks 28 on both sides of the hollow bracket 9 into their respective mounting slots 27. Then push the hollow bracket 9 downwards and place an insulating pad 11 on both sides of the hollow bracket 9. Then place multiple battery cells 2 and multiple hollow brackets 2 10 in sequence inside the mounting groove 7, and place an insulating pad 11 on both sides of the multiple hollow brackets 2 10. When placing multiple hollow brackets 2 10, first insert the mounting blocks 30 on both sides of the multiple hollow brackets 2 10 into their respective mounting slots 2 29, and then push the multiple hollow brackets 2 10 downwards. Then, the threaded rod 22 is rotated, and under the action of the limiting rod 23, the loop transmission frame 24 moves, according to... Figure 5 As shown, the U-shaped transmission frame 24 moves to the left, and the two ends of the U-shaped transmission frame 24 act on the two ends of the translation bracket 14. The translation bracket 14 moves to the left synchronously with the U-shaped transmission frame 24. The translation bracket 14 slides along the two guide rods 16. While the translation bracket 14 moves, it drives multiple trapezoidal blocks 15 to move. The multiple trapezoidal blocks 15 act on the two sliding brackets 13 respectively. The two sliding brackets 13 move away from each other, which in turn drives the two hollow push plates 12 to move away from each other. The two hollow push plates 12 act on the two insulating pads 11 respectively, so that the two insulating pads 11 are tightly attached to the outer side of their respective corresponding battery cells 2. While the U-shaped transmission frame 24 moves, it drives multiple positioning rods 32 to move synchronously. The multiple positioning rods 32 are inserted into the interior of their respective positioning holes 31 to fix the hollow bracket 9 and the U-shaped frame 8, so as to prevent the hollow bracket 9 from moving during subsequent use. As the translation bracket 14 moves, its top multiple trapezoidal blocks 25 move synchronously. Each trapezoidal block 25 acts on one end of its corresponding translation bracket 2 19. The movement process of the second extrusion mechanism inside one of the hollow brackets 2 10 is as follows: The translation bracket 2 19 slides along the two guide rods 2 21. As the translation bracket 2 19 moves, it drives the multiple trapezoidal blocks 2 20 to move. The multiple trapezoidal blocks 2 20 act on the two sliding brackets 2 18, and the two sliding brackets 2 18 move away from each other, thereby driving the two hollow push plates 2 17. The two hollow push plates 17 are far apart from each other and act on the two insulating pads 11 respectively, so that the two insulating pads 11 are tightly attached to the side of their respective corresponding battery cells 2; the movement process of the second extrusion mechanism inside the other multiple hollow brackets 10 is the same as above. While the loop transmission frame 24 and the translation bracket 14 move, multiple positioning blocks 34 move synchronously. The multiple positioning blocks 34 are inserted into the interior of their respective positioning slots 33, so that the multiple hollow brackets 10 are stably fixed inside the outer shell 1, so as to prevent the multiple hollow brackets 10 from moving during subsequent use; After all the cells 2 are placed, the other accessories are fixed inside the outer casing 1 to complete the assembly of the modular energy storage battery. During the use of the energy storage battery, the heat generated between the multiple cells 2 is dissipated through the hollow bracket 1 9 and multiple hollow bracket 2 10. The heat can enter the U-shaped heat dissipation channel 3 through multiple through holes 4 and finally be discharged through the air outlet 5, ensuring that the heat between multiple adjacent cells 2 can be diffused and that the heat will not accumulate between the cells 2, thus avoiding the continuous rise in the internal temperature of the energy storage battery. This ensures that the heat in the energy storage battery can be effectively dissipated, improves the service life of the cells 2, and reduces the safety risks such as cell bulging and thermal runaway. After fixing the first hollow bracket 9 and multiple second hollow brackets 10 inside the outer casing 1, the two first hollow push plates 12 press their respective corresponding insulating pads 11, and the multiple second hollow push plates 17 press their respective corresponding insulating pads 11, thereby pressing and fixing multiple battery cells 2 inside the mounting slot 7. When replacing the insulating pads 11 later, rotate the threaded rod 22 in the opposite direction to reset the return transmission frame 24, and then push the multiple toggle blocks 26 to reset their respective translation brackets 14 and 19. At this time, the two first hollow push plates 12, the multiple second hollow push plates 17 and their respective corresponding insulating pads 11 are loosened, and the insulating pads 11 that need to be replaced can be easily removed.
