[0023] In one embodiment of the present invention, a tray support 81 is fixedly installed on the inner wall of the outer casing 1, a battery support 82 is provided on the upper surface of the tray support 81, a battery pack 83 is snapped into the inside of the battery support 82, an insulating sheet 85 is fixedly installed on the inner walls of the left and right sides of the outer casing 1, and a nickel sheet 84 is provided between the insulating sheet 85 and the end of the battery pack 83.

[0024] Furthermore, the surface of the protection board 7 is fixedly equipped with a controller, converter, and connection port. The bottom and side walls of the housing 1 are provided with holes that are compatible with the connection ports on the protection board 7, so that external electrical devices can connect to the protection board 7 using different interfaces, thereby converting and supplying power through the electronic devices on the protection board 7. At the same time, the bottom of the protection board 7 is provided with a control switch and a power display, so that the user can control the power supply start and stop of the battery pack. The power display can also help the user to observe the remaining power of the battery pack in time, thereby determining whether the battery pack needs to be replaced. Specifically, the protection board 7 is the control panel of the battery module. The terminals, controller, converter, and other accessories on its surface are all existing publicly disclosed technologies in the art, so they will not be described in detail in this embodiment.

[0025] Furthermore, the nickel sheet 84 contacts the electrodes of the battery pack 83 to achieve conductivity. The nickel sheet 84 is connected to the circuit on the protection board 7 via wires, enabling the battery pack 83 to be powered through the nickel sheet 84. It is also electrically connected to external electrical equipment through the protection board 7 and its connection terminals. Simultaneously, an insulating sheet 85 is disposed on the outside of the nickel sheet 84 to provide leakage prevention and insulation protection. Moreover, two sets of tray supports 81 and battery supports 82 are provided, and the two sets of tray supports 81 and battery supports 82 are symmetrically arranged about the vertical central axis of the outer casing 1.
