Slot 413. One end of a locking piece 70 is inserted into the locking hole of the locking portion 35 of the operating member 30 through the through hole 254 of the groove 25 from the inner side of the fixing seat 20. Therefore, the operating member 30 is rotatably mounted on the fixing base 20, and the battery module locking device is assembled. At this time, the elastic member 50 is in the first state, and the protrusion 37 of the operating member 30 abuts against one end of the sliding slot 413 of the latching member 40 away from the receiving space 24 . In the present embodiment, the two lock fasteners 60 and 70 are screws.

When the battery module 10 is to be mounted, the slots 153 on the two sides of the battery module 10 are respectively engaged with the two ribs 231 of the fixing base 20, and the battery module 10 is pushed along the two ribs 231. Enter the accommodating space 24. The first latching portions 12 of the battery module 10 respectively abut the one end of the second latching portion 46 of the latching member 40 adjacent to the elastic member 50, thereby pushing the latching member 40 to a first direction. That is, sliding away from the direction of the elastic member 50, the elastic member 50 is stretched. When the battery module 10 is completely received in the accommodating space 24, the hook grooves 121 of the two first fastening portions 12 of the battery module 10 are respectively aligned with the two latching members 40. The hook 461 of the second latching portion 46, the elastic member 50 elastically pulls the latching member 40 to slide in a second direction opposite to the first direction, so that the two hooks 461 are respectively placed on the hooks The battery module 10 is locked by the slot 121, as shown in FIGS. 4 and 5.

Referring to FIG. 6 , when the battery module 10 is to be taken out, the operating portion 33 of the operating member 30 is rotated to rotate the protrusion 37 of the operating member 30 in the arcuate through groove 256 away from the elastic member 50. The sliding groove 413 of the locking member 40 is topped, so that the locking member 40 is pulled by the protruding portion 37 to slide in the first direction, and the elastic member 50 is stretched. The second latching portion 46 of the latching member 40 is respectively disengaged from the first latching portion 12 of the battery module 10, and the battery module 10 is unlocked.
