Document Type and Number:
WIPO Patent Application WO/2020/206731
Kind Code:
A1
Abstract:
A fast-switching dual-voltage output battery pack, at least comprising two battery sets, wherein the battery sets are connected in parallel by default; the output end of multiple connected battery sets is connected with an output pin; at least two battery sets are provided with PCB protection boards; a frame (2) is arranged on the PCB protection board. The battery pack further comprises a plurality of static contact pieces (3, 4, 5, 6, 7, 8), which are each electrically connected to the positive and negative electrodes of at least two battery sets; a plurality of moving contact pieces (9, 10, 11), which are connected to a sliding assembly; and a pushing assembly connected to an electric power tool, the pushing assembly being connected to the sliding assembly to push the moving contact pieces to move, so as to switch the connected static contact pieces to realize the output of different voltages. The slider assembly is moved to control the movement of the moving contact pieces, thereby achieving fast switching and improving the universality of the battery pack.
