[0002] In order to position and fix the battery cells, a battery cell assembly bracket is usually used. Due to the wide application of lithium-ion batteries, including in consumer electronics, electric vehicles and energy storage systems, the design and manufacture of battery cell assembly brackets have become an important part of the battery manufacturing process. Correct bracket design is crucial to ensure the quality and efficiency of battery assembly, as well as the performance and safety of the final product. It can accurately place the battery cells in the specified position to ensure that the subsequent assembly and connection are accurate. In the process of combining multiple battery cells into a battery pack, the bracket helps manage and maintain the correct spacing and arrangement order between the battery cells.
[0003] Existing battery cells usually adopt the hard pack method. Due to the support of the metal shell, the hard pack battery cells have higher structural integrity and mechanical strength, can withstand greater external pressure and impact, and reduce the risk of physical damage. The stability of the metal shell at high temperature is usually better than that of the soft pack material, which can provide better heat dissipation performance and help the temperature management of the battery.
[0004] However, in some battery pack configurations, soft-pack cells may be easier to expand in series and parallel, while hard-pack cells may have limitations in this regard. At the same time, the shape and size of hard-pack cells are usually fixed, while soft-pack cells can be made into various shapes and sizes as needed, providing greater design flexibility to adapt to the needs of different spaces and shapes, which is not conducive to the use of cells in environments where the external dimensions of portable energy storage products are required to be miniaturized.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 - Figure 3The utility model provides an embodiment: a novel soft-pack battery cell assembly bracket, including an end fixing bracket 1, a thin plate aluminum shell 2 is fixedly connected to the bottom of the end fixing bracket 1, a rectangular array of protrusions 6 is fixedly connected to one side of the outer wall of the end fixing bracket 1, a plurality of fixing grooves 8 are opened inside the end fixing bracket 1, a battery cell 1 3 is slidably connected inside the fixing groove 8, a battery cell 2 4 is slidably connected inside the fixing groove 8, a rectangular array of grooves 12 is opened on the other side of the outer wall of the end fixing bracket 1, the outer wall of the protrusion 6 is slidably connected inside the groove 12, aluminum row card slots 5 are opened on both sides of the top of the end fixing bracket 1, and a wire groove 7 is opened on the top of the end fixing bracket 1;
[0025] Specifically, first, the battery cell 1 3 and the battery cell 2 4 can be packed into the end fixing bracket 1 and the thin aluminum shell 2 through the fixing groove 8 inside the end fixing bracket 1. Secondly, the assembly between the battery cells can be achieved through the end fixing bracket 1. The end fixing bracket 1 has the assembly function in the vertical direction. Through the aluminum card slot 5 and the wire groove 7 on the top of the bracket, the battery cells can be flexibly assembled in the vertical direction. At the same time, the protrusion 6 on one side of the end fixing bracket 1 can slide into the groove 12 on the other side of the bracket to achieve overlapping assembly.
[0026] Reference Figure 1 - Figure 3 A reinforcement component is provided inside the end fixing bracket 1, and the reinforcement component includes a card slot 13 and a card ball 10, the outer wall of the card ball 10 is slidably connected inside the protrusion 6, the card slot 13 is opened inside the groove 12, and the outer wall of the card ball 10 is slidably connected inside the card slot 13;
[0027] Specifically, the spring 11 is placed between the locking ball 10 and the protrusion 6. When the protrusion 6 slides into the groove 12, the spring 11 is compressed. Since the spring 11 has the characteristic of recovering deformation, when the protrusion 6 completely slides into the groove 12, the spring 11 will quickly return to its original state and push the locking ball 10 outward. In this way, the locking ball 10 can be smoothly inserted into the locking groove 13 inside the groove 12, thereby achieving locking between the protrusion 6 and the groove 12.
[0028] Reference Figure 3 and Figure 4A spring 11 is provided on one side of the card ball 10, and the spring 11 is arranged inside the protrusion 6. One end of the spring 11 is fixedly connected to the inner wall of the protrusion 6, and the other end of the spring 11 is fixedly connected to the outer wall of the card ball 10. The inner sides of the end fixed bracket 1 are rotatably connected with a rotating shaft 15, one end of the rotating shaft 15 is fixedly connected to a driving block 9, and the outer walls of the rotating shaft 15 are fixedly connected with worms 16. The outer walls of the end fixed bracket 1 are rotatably connected with rotating shafts 2 18, and one side of the outer wall of the rotating shaft 2 18 is fixedly connected with a worm wheel 17, and the worm wheel 17 is meshed with the worm 16. Slide grooves 21 are provided on both sides of the inner side of the end fixed bracket 1, and one end of the rotating shaft 2 18 is fixedly connected with a rotating rod 19, and both sides of the rotating rod 19 are rotatably connected with transmission rods 20, and one side of the transmission rod 20 is rotatably connected with a splint 14, and the outer wall of the splint 14 is slidably connected to the inside of the slide groove 21;
[0029] Specifically, when the driving block 9 rotates, it first drives the rotating shaft 15 to start rotating. The rotational force of the rotating shaft 15 is transmitted through the worm 16 on both sides, and then drives the worm wheel 17 to start rotating. When the worm wheel 17 rotates, the rotating shaft 2 18 will also rotate accordingly. As the rotating shaft 2 18 rotates, the rotating rod 19 starts to rotate, and transmits power to the clamping plate 14 through the transmission rods 20 on both sides thereof, so that the clamping plate 14 can move linearly along the direction of the slide groove 21. As the rotating rod 19 continues to rotate, the clamping plate 14 continues to approach the battery cell 1 3 and the battery cell 2 4, and finally clamps them fixedly.
[0030] Working principle: the battery cell 1 3 and the battery cell 2 4 can be packed into the end fixing bracket 1 and the thin aluminum shell 2 through the fixing groove 8 inside the end fixing bracket 1, and the battery cells can be assembled by the end fixing bracket 1, and the aluminum row card groove 5 and the wire groove 7 on the top of the end fixing bracket 1 can be assembled in the vertical direction, and at the same time, the protrusion 6 on one side of the end fixing bracket 1 can slide into the groove 12 on the other side of the end fixing bracket 1, so that they can be overlapped and assembled. When the protrusion 6 slides into the groove 12, the card ball 10 can be pushed out of the surface of the protrusion 6 under the action of the spring 11, so as to card When the battery cell 1 3 and the battery cell 2 4 are placed in the fixing groove 8, the driving block 9 can drive the rotating shaft 15 to rotate, and the rotating shaft 15 will drive the worm gears 16 on both sides to rotate, and the worm gears 16 will drive the worm wheel 17 to rotate, and the rotating shaft 2 18 will rotate accordingly, and the rotating rod 19 fixed on the rotating shaft 2 18 will also rotate, so that the transmission rods 20 on both sides of the rotating rod 19 drive the clamping plate 14 to slide in the sliding groove 21, so that the battery cell 1 3 and the battery cell 2 4 are clamped and fixed.
