When the limiting hole 31 is set as a circle, the limiting plate translates along the first direction, and the hole wall of the limiting hole 31 applies a force along the first direction to the unlocking gun 1, so that the unlocking gun 1 can translate along the first direction. When the limiting hole 31 is set as an oblong hole extending along the second direction, the limiting plate translates along the first direction, and the hole wall of the limiting hole 31 applies a force along the first direction to the unlocking gun 1.

The two driving plates 3 are driven by the driving mechanism 4, and can move in the direction away from or close to each other, and the unlocking gun 1 is passed through the limiting hole 31 of the driving plate 3, so that the hole wall of the limiting hole 31 can exert a relative or opposite force on the unlocking gun 1, thereby moving the unlocking gun 1 to different positions to adapt to battery packs of different specifications, thereby improving the compatibility of the battery replacement mechanism 100.

[0048] Among them, the mounting plate 2 is provided with two groups of guide holes 21, and the two groups of guide holes 21 correspond to the limiting holes 31 on the two driving plates 3 respectively, that is, the two groups of limiting holes 31 can both apply a force along the first direction to the unlocking gun 1, and the two groups of correspondingly arranged guide holes 21 can guide the unlocking gun 1, so that the unlocking gun 1 moves to the desired position along the guide holes 21 under the action of the force, and the circular hole in the limiting hole 31 can cooperate with the guide hole 21 whose extension direction is the same as the first direction, so that the unlocking gun 1 can move along the first direction, and the oblong hole in the limiting hole 31 can cooperate with the guide hole 21 whose extension direction is less than 90° from the first direction, so that the unlocking gun 1 can move obliquely, so that the unlocking gun 1 can be adapted to battery packs of different specifications, thereby improving the compatibility of the battery replacement mechanism 100.
