[0034] By arranging both the battery 22 and the first circuit board 23 in the receiving cavity of the housing 21 and making the housing 21 detachably connected to the mounting bracket 1, the power supply component 2 can be detached from the bottom of the trolley separately and quickly; moreover, when detaching the battery 22 and the first circuit board 23, the housing 21 can be removed first, and then the battery 22 and the first circuit board 23 can be taken out from the housing 21, so that the disassembly of the battery 22 and the first circuit board 23 is carried out in the separately detached power supply component 2. Therefore, during later maintenance, it is not necessary to invert the device to detach the first circuit board 23, and the first circuit board 23 can be detached and the fault can be detected more conveniently.

[0035] It should be noted that the mounting bracket 1 is fixed to the side of the base 20 away from the column, that is, the mounting bracket 1 is fixed to the bottom of the base 20; the first circuit board 23 is a battery management circuit board of the battery 22. The detachable connection method between the housing 21 and the mounting bracket 1 can be screw connection, snap connection, snap-fit connection, etc., and preferably screw connection, which can make the connection between the housing 21 and the mounting bracket 1 more firm. For example, as Figure 2 and Figure 3 shown, a locking screw 7 is provided on the housing 21, and a connection hole 12 is provided on the mounting bracket 1. The locking screw 7 is installed in the connection hole 12 to realize the mutual fixation between the housing 21 and the mounting bracket 1.

The first circuit board 23 is received in the first receiving sub-cavity 2111, and the battery 22 is received in the second receiving sub-cavity 2112. Thus, the battery 22 and the first circuit board 23 are separated by the first partition 24 to prevent the heat generated during the operation of the battery 22 from affecting the normal use of the first circuit board 23.

[0037] In some embodiments, the plate surface of the first partition 24 is provided with heat dissipation holes, so that part of the heat in the second receiving sub-cavity 2112 can be conducted to the first receiving sub-cavity 2111, preventing the temperature in the second receiving sub-cavity 2112 from rising rapidly due to excessive heat accumulation. The plate surface of the mounting bracket 1 is also provided with heat dissipation holes to dissipate the heat generated by the power supply component 10.

[0038] Please refer to Figure 2 , the housing 21 includes a bottom case 211, a first upper cover 212 and a second upper cover 213.
