A symmetrically distributed inner protective plate 18 is movably installed on the outer side of the battery body 11. One end of the first spring 17 is fixedly connected to the inner protective plate 18. A symmetrically distributed damper 19 is fixedly installed on the outer side of the protective cover 15. One end of the damper 19 is fixedly connected to the outer protective plate 20. A second spring 21 is fixedly connected to one end of the damper 19. One end of the second spring 21 is fixedly connected to the outer protective plate 20. A symmetrically distributed bonding block 22 is fixedly installed on the bottom surface of the protective cover 15. A first bolt 23 is threaded onto the opposite end of each bonding block 22.

[0020] A T-shaped plate 24 is fixedly installed at the top of the frame body 1. An array of inserted rods 25 are slidably inserted into the top of the T-shaped plate 24. One end of the inserted rods 25 is slidably inserted into the inner side of the U-shaped plate 12. A retaining ring 26 is fixedly installed at the top of each inserted rod 25. A third spring 27 is fixedly installed at one end of each retaining ring 26. One end of the third spring 27 is fixedly connected to the T-shaped plate 24. Symmetrically distributed second bolts 28 are threaded on the top surface of the T-shaped plate 24. One end of the second bolt 28 is threaded on the inner side of the U-shaped plate 12.

[0021] By adopting the above technical solution, four insertion rods 25 are inserted into the U-shaped plate 12 and positioned securely by the action of the third spring 27. Then, the second bolt 28 is used to install it into the U-shaped plate 12 to complete the installation. After removing the second bolt 28, the X-shaped plate 29 is pulled to drive the insertion rods 25 out, which makes it easy to disassemble the U-shaped plate 12 and facilitates the maintenance and inspection of the components on the U-shaped plate 12 in the later stage.

[0022] An X-shaped plate 29 is fixedly installed at the top of the fixing ring 26.

[0023] By adopting the above technical solution, the X-shaped plate 29 facilitates the movement of the fixed ring 26 and the insertion rod 25.

[0024] Symmetrically distributed limiting blocks 30 are fixedly installed on the outer side of each locking post 13, with one end of the limiting block 30 being in contact with the rotating block 14.

[0025] By adopting the above technical solution, the rotating block 14 is limited by setting a limit block 30.

[0030] Working principle: First, after the battery body 11 is assembled with the frame body 1, the protective cover 15 is pulled to rotate relative to each other, thereby covering the battery body 11. The rotating block 14 rotates on the locking post 13 to cooperate with the movement of the protective cover 15. After the protective cover 15 is in place, the first bolt 23 is used to connect and fix the two sets of bonding blocks 22. At the same time, the first spring 17 on the inner side of the protective cover 15 pushes the inner protective plate 18 to wrap the battery body 11. With the help of the damper 19, the second spring 21 and the outer protective plate 20 on the outer side of the protective cover 15, the battery body 11 is protected by both internal and external forces, which improves the impact resistance and further improves the service life. The four insert rods 25 are inserted into the U-shaped plate 12 by the action of the third spring 27 to fix and position it. Then, the second bolt 28 is used to install it into the U-shaped plate 12 to complete the installation. The second bolt 28 is removed and the X-shaped plate 29 is pulled to drive the insert rods 25 out, which makes it easy to disassemble the U-shaped plate 12 and facilitates the maintenance and inspection of the components on the U-shaped plate 12 in the later stage.
