[0028] Furthermore, the protection pad 25 can be made of rubber material. The protection pad 25 is located between the T-shaped pressure strip 26 and the battery module 1 , and plays a certain protective and anti-slip role for the battery module 1 .

[0029] The side portion of the bottom end of the stud 28 is fixedly connected to the inner ring of the limiting ring 29 , and the limiting ring 29 is located at the top position of the main beam 22 .

[0030] Furthermore, the limiting ring 29 is used to limit the length of the stud 28 entering the threaded through hole 210 .

[0031] A gasket 24 is provided between the locking nut 23 and the T-shaped pressure strip 26 , and the inner ring of the gasket 24 is slidably sleeved on the side of the stud 28 .

[0032] Furthermore, the gasket 24 is used to expand the force-bearing area of ​​the T-shaped pressure strip 26 to prevent the T-shaped pressure strip 26 from being crushed by the locking nut 23 .

[0033] The buffer protection frame 3 includes: a top mounting plate 34, an oblique support rod 35 and a sliding block 33.

[0035] Furthermore, when used in a bumpy and vibrating environment, the box body 21 will press the top mounting plate 34 downward, and the top mounting plate 34 will push the sliding block 33 to move in the direction of the support plate 31 through the oblique support rod 35, so that the sliding block 33 compresses the buffer spring 32, so that the buffer spring 32 absorbs and buffers the energy generated by the bumpy vibration, thereby achieving buffering protection for the battery module 1.
