Description

Technical Field

[0001] This utility model belongs to the field of battery cell support technology, and in particular relates to a plastic rear integrated support for use with cylindrical battery cells. Background Technology

[0002] Cylindrical cells are a common battery cell shape, widely used in power tools, electric vehicles, and energy storage systems due to their stable structure and excellent heat dissipation characteristics. Integrated brackets are structures that arrange and secure multiple cylindrical cells together, used for battery module assembly and layout optimization. Integrated brackets not only help maintain a stable battery structure but also improve heat dissipation efficiency and simplify the cell connection process, making them widely used in electric vehicles, energy storage systems, and various power tools.

[0003] When cylindrical battery cell modules are in operation, they need to be connected to FPCs (Flexible Printed Circuits). This connection requires an integrated bracket. However, due to their structural design, existing integrated bracket structures require an additional fixing base when connecting to the FPC, increasing the number of components, reducing product integration, and making it difficult to effectively secure the FPC, leading to loosening. Therefore, this utility model provides a plastic rear integrated bracket for use with cylindrical battery cells, which is of great significance in addressing these problems. Utility Model Content

[0004] This utility model provides a plastic rear integrated bracket for use with cylindrical battery cells. The FPC can be installed and fixed by the threaded grooves on each fixing seat on one side of the bracket body and the matching bolts. The additional design of related fixing structures effectively reduces the number of parts and improves the integration of the product, so as to facilitate the installation and disassembly of related components. The limiting block can play a preliminary role in limiting the position of the FPC to prevent the position from shifting. The limiting grooves can limit the FPC interface to further improve the stability of the FPC and prevent it from loosening after installation. In summary, it solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a plastic rear integrated bracket for use with cylindrical battery cells, comprising a battery cell module and a pair of bracket bodies. The battery cell module integrates a cylindrical battery cell and an FPC (Flexible Printed Circuit). One end of the FPC extends to the outside of the battery cell module, and the FPC is provided with several FPC interfaces. The bracket bodies are installed on one side of the battery cell module, and bolts are threaded to both the top and bottom ends of the bracket bodies. A gap is left between the pair of bracket bodies. A pair of limiting blocks and several fixing seats are respectively provided on the side wall of the bracket bodies. The fixing seats are located between the pair of limiting blocks, and each fixing seat is provided with a threaded groove.

[0007] Furthermore, the spacing between the pair of limiting blocks is equal to the width of the FPC extending to the outside of the cell module.

[0008] Furthermore, the fixing seats are linearly and equidistantly distributed, and a limiting groove is provided between each pair of adjacent fixing seats. The width of the limiting groove is equal to the length of the FPC interface.

[0009] The present invention has the following advantages over the prior art:

[0010] (1) When using the plastic rear integrated bracket with cylindrical battery cells in this utility model, the FPC can be installed and fixed by the threaded grooves on each fixing seat on one side of the bracket body and the matching bolts. The additional design of related fixing structures effectively reduces the number of parts and improves the integration of the product, so as to install and disassemble the related parts.

[0011] (2) When using the plastic rear integrated bracket with cylindrical battery cells in this utility model, the limiting block can play a preliminary limiting role to prevent the position of the FPC from shifting.

[0022] Please see Figure 1-4As shown, this utility model discloses a plastic rear integrated bracket for use with cylindrical battery cells, comprising a battery cell module 1 and a pair of bracket bodies 2. The battery cell module 1 integrates a cylindrical battery cell and an FPC 3. One end of the FPC 3 extends to the outside of the battery cell module 1, and the FPC 3 is provided with several FPC interfaces 4. The bracket bodies 2 are mounted on one side of the battery cell module 1, and bolts are threaded to both their top and bottom ends. Aluminum plates are provided on the top and bottom of the battery cell module 1. The bolts can fix the top and bottom of the pair of bracket bodies 2 to the top and bottom aluminum plates of the battery cell module 1, respectively. A gap is left between the pair of bracket bodies 2 to accelerate heat dissipation from the battery cell module 1, thereby achieving a heat dissipation effect and preventing heat concentration in the battery cell. The internal structure of module 1 is prone to overheating. The bracket body 2 is made of PA66+20%GF engineering plastic, which has high strength and certain toughness, effectively meeting the assembly and fixing requirements of the battery cell module 1, while also greatly reducing the overall weight. The side walls of the bracket body 2 are provided with a pair of limiting blocks 5 and several fixing seats 6. The fixing seats 6 are located between the pair of limiting blocks 5, and each fixing seat 6 has a threaded groove 7. A bolt that matches it can be screwed into the threaded groove 7. The FPC3 can be installed and fixed by the threaded groove 7 on each fixing seat 6 and the matching bolt. The additional design of related fixing structures effectively reduces the number of parts and improves the integration of the product, so as to facilitate the installation and disassembly of related components.

[0023] The spacing between the pair of limiting blocks 5 is equal to the width of the FPC3 extending to the outside of the cell module 1. The top and bottom of the FPC3 extending to the outside of the cell module 1 can be attached to the inner walls of the pair of limiting blocks 5 to play a preliminary limiting role, thereby preventing the position of the FPC3 from shifting.

[0024] The fixing seats 6 are linearly and equidistantly distributed, and each pair of adjacent fixing seats 6 is provided with a limiting groove 8. The width of the limiting groove 8 is equal to the length of the FPC interface 4. When the FPC3 is installed, each FPC interface 4 can be aligned and fitted against the inner wall of the corresponding limiting groove 8. At this time, the FPC interface 4 can be limited by each limiting groove 8 to further improve the stability of the FPC3 and prevent it from loosening after installation.

[0027] The working principle of this utility model is as follows:

[0028] In use, this utility model allows for the bolt-fixed connection of the top and bottom of a pair of bracket bodies 2 to the top and bottom aluminum plates of the battery cell module 1, respectively. The bracket bodies 2, as structural components, serve to fix the battery cell module 1. A gap is left between the pair of bracket bodies 2 to accelerate heat dissipation from the battery cell module 1, thus preventing heat concentration inside the battery cell module 1 and overheating. The bracket bodies 2 are made of PA66+20%GF engineering plastic, possessing high strength and a certain degree of toughness, effectively meeting the assembly and fixing requirements of the battery cell module 1 while significantly reducing the overall weight. The side walls of the bracket bodies 2 are respectively provided with a pair of limiting blocks 5 and several fixing seats 6, each fixing seat 6 having a threaded groove 7. The FPC3 can be screwed into the screw 7 and the screw 7 on each fixing seat 6 can be used to install and fix the FPC3. The additional design of related fixing structure effectively reduces the number of parts and improves the integration of the product, so as to facilitate the installation and disassembly of related components. The top and bottom of the FPC3 extending to the outside of the cell module 1 can be respectively attached to the inner wall of a pair of limiting blocks 5 to play a preliminary limiting role, thereby preventing the position of the FPC3 from shifting. When the FPC3 is installed, each FPC interface 4 can be aligned and attached to the inner wall of the corresponding limiting groove 8. At this time, the FPC interface 4 can be limited by each limiting groove 8 to further improve the stability of the FPC3 and prevent it from loosening after installation.
