DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a new energy lithium battery installation buffer device, including a protective box 1, threaded holes 2 are opened on both sides of the protective box 1, first fixed blocks 3 are connected to the inner walls on both sides of the protective box 1, a first circular plate 4 is connected to the lower part of the interior of the protective box 1, a first inclined block 5 is connected to the first circular plate 4, a first spring 6 is connected to the first inclined block 5, a second inclined block 7 is connected to one end of the first spring 6, a second circular plate 8 is connected to the second inclined block 7, a mobile box 9 is connected to the second circular plate 8, a card slot 25 is opened on the outer wall of the mobile box 9, the card block 24 is designed as a right-angled triangle and is embedded in the card slot 25, the card slot 25 is hooked by the right-angled triangle card block 24, thereby fixing the pressure plate 13 to prevent the pressure plate 13 from falling off, so that the pressure plate 13 can press and fix the battery body 12.

[0022] A second spring 10 is connected inside the mobile box 9, and the mobile box 9 is connected to a movable plate 11 through the second spring 10. A battery main body 12 is installed in the mobile box 9, and a connecting electrode 19 is arranged above the battery main body 12. A base 20 is connected below the battery main body 12. Positioning grooves 21 are provided on both sides of the base 20, and the positioning plates 15 are inserted into the positioning grooves 21. By inserting the two positioning plates 15 into the positioning grooves 21 on both sides of the base 20, the two positioning plates 15 can lock and hook the base 20, thereby preventing the battery main body 12 from sliding in the mobile box 9.

[0023] A pressure plate 13 is clamped on the top of the moving box 9, an anti-slip pad 22 is connected to the bottom of the pressure plate 13, elastic plates 23 are connected on both sides of the pressure plate 13, and a clamping block 24 is connected to the side of the elastic plate 23 facing the moving box 9. When the pressure plate 13 presses the battery body 12, the anti-slip pad 22 will deform, thereby buffering the contact between the pressure plate 13 and the battery body 12, and increasing the friction between the pressure plate 13 and the battery body 12 to prevent the pressure plate 13 from sliding.

[0024] The inner walls on both sides of the movable box 9 are connected with fixed rods 14, and the positioning plates 15 are rotatably connected to the fixed rods 14. Inclined surfaces are arranged on both sides of the movable plate 11. The positioning plate 15 is C-shaped as a whole and the lower part is in contact with the inclined surfaces on both sides of the movable plate 11. Torsion springs 27 are connected to both sides of the positioning plate 15, and one end of the torsion spring 27 is connected to the inner wall of the movable box 9. Through the inclined surfaces on both sides of the movable plate 11, the movable plate 11 moving downward can flexibly and conveniently push the positioning plate 15 to rotate, and when the positioning plate 15 rotates, the torsion spring 27 will be twisted, so that when the battery body 12 is disassembled, the rotation of the torsion spring 27 can be used to return the positioning plate 15 to its initial position.

[0025] The mobile box 9 is connected to connecting plates 16 on both sides, and the connecting plate 16 is connected to a second fixed block 17. The second fixed block 17 is rotatably connected to a damper 18 via a pin shaft, and the damper 18 is connected to a third spring 26. The end of the damper 18 away from the second fixed block 17 is rotatably connected to the first fixed block 3 via a pin shaft. A total of four dampers 18 are distributed on the connecting plate 16 in a rectangular array. By compressing or stretching multiple dampers 18 and the third spring 26 at the same time, the buffering effect of vibration and impact force is improved, thereby avoiding damage to the battery body 12 due to excessive impact force.

[0026] The working principle of the utility model is:

[0027] The staff puts the battery body 12 into the mobile box 9. As the battery body 12 is put in, the movable plate 11 is pushed down by the battery body 12. While moving down, the movable plate 11 pushes the positioning plate 15 through the inclined surfaces on both sides, so that the positioning plate 15 rotates with the fixing rod 14 as the center, so that one end of the positioning plate 15 is inserted into the positioning groove 21, and the battery body 12 is fixed in the mobile box 9. Then, the pressing plate 13 is contacted with the battery body 12, and the elastic plate 23 is pressed at the same time to make the elastic plate 23 rotate. The force plate 23 is deformed so that the card block 24 can be inserted into the card slot 25, thereby fixing the pressure plate 13, so that the pressure plate 13 can press and fix the battery body 12. When the battery body 12 is hit, the mobile box 9 will shake, thereby compressing or stretching multiple first springs 6 to buffer the impact force of the collision. At the same time, the damper 18 will rotate, and the third spring 26 will be compressed or stretched by the mobile box 9 together with the damper 18, thereby buffering the impact force and the shaking of the mobile box 9.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
