[0021] The lithium battery dividing airbag 501 can be used to divide multiple lithium battery bodies 4 to prevent collisions between the multiple lithium battery bodies 4. At the same time, the gas inside the lithium battery dividing airbag 501 expands due to heat, making it easier to squeeze and fix the lithium battery body 4, thereby preventing the lithium battery body 4 from shaking and expanding when heated, and can better protect the lithium battery body 4.

[0022] like Figure 1 , Figure 2 and Figure 4 A first water cooling circulation assembly 2 is installed on one side of the interior of the lithium battery pack protection box 1, and a second water cooling circulation assembly 3 is installed on the other side of the interior of the lithium battery pack protection box 1. The structure of the first water cooling circulation assembly 2 is completely consistent with the structure of the second water cooling circulation assembly 3, and the first water cooling circulation assembly 2 and the second water cooling circulation assembly 3 are symmetrical about the central axis of the lithium battery pack protection box 1;

[0023] The second water-cooling circulation component 3 has the same structure as the first water-cooling circulation component 2, thereby performing double-sided cooling on the inside of the equipment.

[0024] like Figure 4 As shown, the first water-cooling circulation assembly 2 includes a water-cooling circulation pipe 201 and a condensing unit 202, and the end of the water-cooling circulation pipe 201 is connected to the condensing unit 202;

[0025] During operation, the condensing unit 202 will cool the water inside the water-cooling circulation pipe 201, and then circulate the cold water inside the equipment through the water-cooling circulation pipe 201, thereby cooling the inside of the equipment to ensure that the lithium battery body 4 inside the lithium battery pack protection box 1 is at a suitable temperature, and prevent the temperature of the lithium battery body 4 from being too high, causing the lithium battery body 4 to spontaneously combust, etc., affecting the operation of the equipment.

[0026] like Figure 3 As shown, a battery pressing assembly 6 is provided on the lithium battery pack protection box 1, and the battery pressing assembly 6 includes a protection box upper cover plate 601, a pressing spring 602 and a pressing plate 603, the lower end of the protection box upper cover plate 601 is connected to the pressing spring 602, and the lower end of the pressing spring 602 is connected to the pressing plate 603, the pressing plate 603 forms an elastic structure through the pressing spring 602 and the protection box upper cover plate 601, and the pressing spring 602 and the pressing plate 603 are symmetrically arranged in two groups about the central axis of the protection box upper cover plate 601;
