Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical electric cores, in particular to a fixing bracket and an electric core module. Background Art

[0002] Although the existing battery holder design uses plastic materials to achieve cost-effectiveness and a certain degree of durability, its stability is still an issue that cannot be ignored in practical applications. Since the top cover and the base are independent of each other, although they can each fix the battery to a certain extent, the overall structure is prone to loosening or deformation when subjected to external impact or vibration, thus affecting the safety and stability of the battery.

[0003] Therefore, the design of future battery cell brackets needs to pay more attention to improving stability. The new direction will be committed to developing a more solid and stable battery cell bracket, which can better fix the battery cell by optimizing the structural design, using higher-strength materials or adding fixing points, and reduce looseness or deformation caused by external forces.

[0004] In addition, in order to meet the needs of different application scenarios, the newly designed battery holder should also have higher flexibility and adjustability. For example, the number of battery cells can be freely increased or decreased through modular design or adjustable fixtures to meet the needs of battery packs of different capacities and sizes.

[0005] In short, future cell bracket designs will focus more on improving stability and flexibility, and provide safer, more reliable support and protection for cell groups by optimizing design and material selection. Utility Model Content
