[0005] A support hole structure of adaptation 32140 electric core, including first fixed support shell and second fixed support shell, be provided with a plurality of electric core bodies between the first fixed support shell and the second fixed support shell fixedly.

[0006] Preferably, the first fixed support shell includes a plurality of fixed screws, which has the beneficial effect of fixing the support structure and improving the stability of the structure.

[0007] Preferably, the protective plate is fixed inside the first fixed support shell by the fixed screws, which has the beneficial effect of connecting the first fixed support shell together by the fixed screws, effectively protecting the electric core inside the support and improving the stability of the structure of the support.

[0008] Preferably, the first fixed support shell bottom is 18mm away from the mouth, the first fixed support shell 1 diameter is 33.5±0.1, and the height is 5mm.

[0009] Preferably, the 5mm height position is 0.5° to the first fixed support shell mouth, and the mold pulling position height is 13mm.

[0010] Preferably, the support of the above structure is assembled with the electric core, the inner wall diameter is 33.5mm±0.1, and the height is 5mm.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] This bracket hole structure, adapted for 32140 battery cells, is first used by connecting the first fixing bracket shell to the bracket using fixing screws. After installation, it is ready for use. The bottom of the bracket is 18mm from the opening, the bracket diameter is 33.5±0.1mm, and the height is 5mm. No draft treatment is performed on this section during molding. A draft of 0.5° is performed from the 5mm height position to the bracket opening, with a draft height of 13mm. The junction between the draft start line and the non-drafted section is rounded with an R100 radius to increase guidance. After the bracket with the above structure is assembled with the battery cell, the inner wall diameter is 33.5mm±0.1mm and the height is 5mm. Compared with the previous structure where the battery cell sidewall was in edge contact, the new structure ensures that the sidewall of the battery cell is in surface contact, which more effectively improves the reliable positioning effect of the battery cell in the bracket.

[0013] The advantages of this bracket hole structure adapted to 32140 battery cells are that by changing the gears in the bracket hole structure, the problem of cell shaking caused by large mating clearance in the bracket is effectively improved, and the gap between the battery cell and the bracket is reduced. Especially for brackets with multiple holes, the reduction of the mating clearance between a single battery cell hole and the bracket greatly improves the consistency and stability of the overall module, which can effectively improve the safety of the overall structure, thereby increasing the safety and service life of the battery cell during use.
