In order to provide the battery with a heat preservation effect so that the battery can adapt to the low temperature and humid environment, a number of insulation plates for surrounding the battery are installed in the accommodating cavity. The main advantage of the design of this application lies in the design of its sealing structure. Through the combination of the sealing ring block and the sealing ring groove, and the sealing ring at the bottom of the sealing ring groove, moisture and other liquids are effectively prevented from entering the interior of the battery module. At the same time, the insulation plate in the accommodating cavity can ensure that the battery maintains a suitable temperature during operation, improve the efficiency and life of the battery, so as to solve the problem of reduced charging efficiency of the battery module in a low temperature and humid environment.

[0008] Optionally, a heating film is arranged between the battery and the insulation plate, and a temperature sensor is arranged on the battery.

This design can make the screw head be located below the surface of the second shell, ensuring the neat and flat appearance. The side wall of the receiving groove is provided with a drain port to prevent water mist or other liquids from being retained in the receiving groove. Through the drain port, any moisture or water mist accumulated in the receiving groove can be effectively discharged, avoiding corrosion, electrical failure or other problems caused by liquid accumulation.

[0016] Optionally, a sealing sleeve for sleeve-mounting the screw head is provided on the second shell, and the sealing sleeve is made of waterproof material.
