The explosion-proof valve 16 can relieve the pressure in the accommodating cavity when thermal runaway occurs in the battery module, thereby effectively preventing the battery pack from exploding.

[0077] In this embodiment, the hoisting portion 12 and the second mounting hole 14 for mounting the explosion-proof valve 16 are both arranged on the first plate body 10, which improves the structural integration and facilitates production and processing.

[0078] According to an embodiment of the utility model, the main body is provided with a third mounting hole 61 , and the third mounting hole 61 and the second mounting hole 14 are arranged diagonally on the main body.

The first end of the fire nozzle 62 is connected to the fire pipeline, and the second end of the fire nozzle 62 is located in the accommodating space. When thermal runaway occurs in the battery module, the fire pipeline can provide a fire medium to the fire nozzle 62, and the fire medium can be sprayed from the fire nozzle 62 into the accommodating cavity, thereby cooling the battery module and extinguishing the fire.

[0080] In this embodiment, the fire-fighting medium sprayed out by the fire-fighting nozzle 62 is in the form of atomization or gas. When the battery module has thermal runaway, the gas generated by the thermal runaway is sprayed out from the explosion-proof valve 16. According to Bernoulli's principle, the pressure is low where the flow rate is high. The location of the explosion-proof valve 16 will generate suction on the fire-fighting medium. In order to increase the coverage area of ​​the fire-fighting medium in the accommodation space, the distance between the fire-fighting nozzle 62 and the explosion-proof valve 16 can be increased.

[0081] Based on this, Figure 1 and Figure 3 As shown, the third mounting hole 61 and the second mounting hole 14 are arranged diagonally on the main body. For example, the third mounting hole 61 can be arranged near the upper left corner of the main body, and the second mounting hole 14 can be arranged near the lower right corner of the main body, so as to increase the distance between the fire nozzle 62 and the explosion-proof valve 16, so that the fire-fighting medium will not be sprayed out of the explosion-proof valve 16 quickly after being sprayed out of the fire nozzle 62, thereby increasing the time and space for the fire-fighting medium to pass through the accommodating cavity, so that the fire-fighting medium can cover the entire battery module as much as possible, which can effectively improve the suppression effect of thermal runaway.
