Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 6, an embodiment of the invention provides a charger 100, which includes a housing assembly 10 and a power transforming module 20. The housing assembly 10 includes a first electrical connection interface 11 and a battery interface 12 for connecting with a battery 1002 (shown in fig. 13 and 14) of the movable platform 1001.

In the charger 100 of the above embodiment, the power transforming module 20 can be quickly removed and replaced. Therefore, the power transforming module 20 matched with the battery 1002 to be charged can be selected to be assembled on the housing assembly 10 to assist the charging of the battery 1002 to be charged according to the capacity of the battery 1002 to be charged. Thus, the same housing assembly 10 can be compatible with different power transformation modules 20, so that the same charger 100 can assist the batteries 1002 with different capacities to charge, the power is diversified, the structure is simple, and the cost of the housing assembly 10 can be reduced.

Illustratively, when the power transformer module 20 is located on the housing assembly 10 and assembled to the predetermined position, the first electrical connection interface 11 is mechanically connected and mated with the second electrical connection interface 21, and the first electrical connection interface 11 is electrically conducted with the second electrical connection interface 21. When the first electrical connection interface 11 and the second electrical connection interface 21 are separated from mechanical engagement, the first electrical connection interface 11 and the second electrical connection interface 21 are electrically disconnected.

For example, when the charger 100 assists to charge the battery 1002, the second electrical connection interface 21 of the power transforming module 20 needs to be mechanically and electrically connected with the first electrical connection interface 11 of the housing assembly 10, the power interface 22 needs to be electrically connected with the power supply device 2001, and the battery interface 12 needs to be electrically connected with the battery 1002.
