[0023] A positioning groove 3 is formed on the upper surface of the bottom plate 1 , and an energy storage battery body 13 is placed inside the positioning groove 3 . A plurality of guard bars 4 are located outside the energy storage battery body 13 .

[0024] The multiple guard bars 4 can provide good protection for the energy storage battery body 13 on the outside, and the positioning grooves 3 can prevent the energy storage battery body 13 from shifting on the upper surface of the base plate 1 .

[0025] A rubber pad 12 is fixedly connected to the lower surface of the top plate 2 .

[0026] When the top plate 2 is pressed against the upper surface of the energy storage battery body 13 , the rubber pad 12 can buffer and protect the surface of the energy storage battery body 13 .

[0027] Support legs 10 are fixed to the four corners of the lower surface of the bottom plate 1 , and slots 11 for receiving the support legs 10 are provided to the four corners of the upper surface of the top plate 2 .

[0028] When two protective devices are stacked, the upper base plate 1 can be placed on the surface of the lower top plate 2, and the support feet 10 on the lower surface of the upper base plate 1 can be inserted into the slots 11 on the surface of the lower top plate 2 to prevent the two protective devices from sliding against each other.

[0029] The plug-in assembly 5 includes a vertical rod 51 fixed to the lower surface of the top plate 2, and the docking assembly 6 includes a connecting sleeve 61 fixed to the upper surface of the bottom plate 1, and a card hole 62 is provided on the side wall of the connecting sleeve 61. The bottom end of the vertical rod 51 is inserted into the connecting sleeve 61, and a groove 52 is provided at the bottom end of the vertical rod 51 and close to the card hole 62.

The card tooth 54 is inserted into the card hole 62 at the end away from the spring 53.

[0030] When connecting the top plate 2 and the bottom plate 1, the bottom ends of the two vertical rods 51 can be inserted into the connecting sleeves 61 on both sides of the upper surface of the bottom plate 1.

[0033] Working principle: When assembling the protective device, place the energy storage battery body 13 in the positioning groove 3 on the upper surface of the bottom plate 1, then cover the top plate 2 on the upper surface of the energy storage battery body 13, and insert the bottom ends of the two vertical rods 51 on the lower surface of the top plate 2 into the two connecting sleeves 61 respectively. The teeth 54 at the bottom of the vertical rods 51 are engaged with the holes 62 on the connecting sleeves 61 to achieve a fixed connection between the vertical rods 51 and the connecting sleeves 61, thereby squeezing and fixing the energy storage battery body 13 between the bottom plate 1 and the top plate 2. At this time, the multiple guard bars 4 on the outside of the energy storage battery body 13 can protect the energy storage battery body 13 without affecting the normal wiring of the energy storage battery body 13. When multiple protective devices are arranged for transportation, the two adjacent bottom plates 1 can be fixedly connected by the connecting plate 8. The multiple protective devices are connected into a whole to ensure stability during placement.
