[0038] Example 2

[0039] The difference between this embodiment and the first embodiment is that the buffer structure 4 includes an anti-rust coating 41, an elastic component 42 and a reinforcement layer 43. The inner wall of the steel sheet 7 is provided with the reinforcement layer 43. The inner side of the reinforcement layer 43 is provided with the anti-rust coating 41.

[0043] When this embodiment is in use, a reinforcement layer 43 is provided on the inner wall of the steel sheet 7. The reinforcement layer 43 is made of a high-strength metal material, thereby improving the strength of the steel sheet 7 and preventing the steel sheet 7 from being deformed.

The elastic component 42 composed of a rubber layer 421 and a sponge layer 422 can improve the protective performance of the polymer battery body 1.

[0044] Working principle and use process of the utility model: When the utility model is used, when the steel sheet 1 7 and the steel sheet 2 9 are installed and fixed, the fixing block 54 on the side of the mounting block 2 10 will be inserted into the fixing groove 57 inside the clamping seat 2 8, and can cooperate with the fixing component 1 56 and the fixing hole 55 to achieve the fixation of the steel sheet 1 7 and the steel sheet 2 9, and at the same time, the clamping block 53 on the side of the mounting block 3 will be inserted into the clamping groove 51 inside the clamping seat 6, and can cooperate with the fixing component 2 58 and the clamping hole 52 to reinforce the steel sheet 1 7 and the steel sheet 2 9. The fixing effect of the sheet 2 9 is that when the steel sheet 1 7 and the steel sheet 2 9 are connected and fixed, the slider 564 inside the sliding groove 563 is slid, and the slider 564 drives the fixing rod 561 to compress the spring 1 562 and embed into the inside of the clamping seat 2 8. When the fixing block 54 is inserted into the inside of the fixing groove 57, the slider 564 is released at this time, and the spring 1 562 rebounds, which can drive the fixing rod 561 to insert into the inside of the fixing hole 55, thereby realizing the fixed connection between the steel sheet 1 7 and the steel sheet 2 9. When the steel sheet 1 7 and the steel sheet 2 9 need to be connected and fixed, the fixing effect of the sheet 2 9 is that when the steel sheet 1 7 and the steel sheet 2 9 need to be connected and fixed, the fixing rod 561 is inserted into the fixing hole 55, and the fixing hole 55 is inserted into the fixing hole 55. When disassembling, slide the slider 564 in the slide groove 563 again, and the slider 564 drives the fixing rod 561 to slide out from the fixing hole 55, so that the steel sheet 1 7 and the steel sheet 2 9 can be separated. At the same time, when the steel sheet 1 7 and the steel sheet 2 9 are docked and fixed, the block 53 on the side of the mounting block 3 will be inserted into the slot 51 on the side of the holder 1 6, and drive the bayonet 581 to compress the limit plate 582 and the spring 2 583. When the bayonet hole 52 is aligned with the bayonet 581, the spring 2 583 rebounds, thereby bringing By inserting the movable latch pin 581 into the latch hole 52, the fixed connection between the steel sheet 1 7 and the steel sheet 2 9 can be achieved; by providing a reinforcement layer 43 on the inner wall of the steel sheet 7, the reinforcement layer 43 is made of a high-strength metal material, thereby improving the strength of the steel sheet 7 and preventing the steel sheet 7 from being deformed; by providing the anti-rust coating 41, the anti-rust performance of the steel sheet 7 can be reduced; and by the elastic component 42 composed of the rubber layer 421 and the sponge layer 422, the protective performance of the polymer battery body 1 can be improved.
