By adopting the above technical solution, when installing or disassembling the battery, it is only necessary to connect or disconnect the screw rod and the threaded hole.

As an improvement of the present invention, several expansion joints are arranged on the support column.

By adopting the above technical solution, several expansion joints arranged on the support column can make the whole support column perform telescopic operation according to the size of the battery, so as to ensure that the top plate and the bottom plate are always in contact with the surface of the battery.

As an improvement of the present invention, both the top plate and the bottom plate are provided with a friction coating.

By adopting the above technical solution, the provision of the friction coating can increase the frictional force between the battery and the top plate and the bottom plate, thereby preventing the separation between the battery and the placement area.

The beneficial effects of the utility model are as follows: when the battery needs to be radiated in hot weather or during long-term driving, the water-cooling pump is started first, and the water-cooling pump flows out the liquid in the water tank, and the liquid is cooled by the water-cooling pump and then conveyed from the upper liquid pipe. In the upper interlayer, since the battery is located between the top plate and the bottom plate, the cooled liquid enters the upper interlayer and takes away part of the heat conducted by the battery. Finally, the liquid in the upper interlayer flows from the connecting pipe into the upper chamber in the lower interlayer. In order to prevent the liquid from entering the lower interlayer too fast during the falling process, the lower interlayer is divided into an upper chamber and a lower chamber. The liquid flowing into the lower interlayer first enters the upper chamber, then flows into the lower chamber through the lower liquid pipe, and finally flows into the lower chamber. It flows back into the water tank through the lower chamber; at the same time, an air-cooling mechanism is also provided, which can assist in accelerating the cooling operation of the battery. The traditional battery is placed vertically. If the battery needs to be placed in the storage area, First place the battery laterally, then fix the support column with the threaded disassembly assembly, and finally the battery is placed in the placement area.
