When the vehicle to be switched runs to one side of the mobile switching station (namely the outer side of the mobile support plate 7), the first detection element on the mobile support plate 7 detects the vehicle to be switched and controls the switching mechanism to move along the track, and when the second detection element detects the vehicle to be switched, the switching mechanism stops moving, so that the vehicle to be switched is accurately positioned. At the moment, the supporting arm 11 of the battery replacing mechanism extends out, so that after the grabbing mechanism grabs the battery on the vehicle to be replaced, the supporting arm 11 contracts, the grabbing mechanism returns to the position above the movable supporting plate 7, then the battery replacing mechanism moves to the position of the vacant position of the battery bin, and the supporting arm 11 drives the grabbing mechanism to move to the position above the vacant position of the battery bin and move downwards, so that the old battery is placed at the vacant position of the battery bin; and continuously, moving the battery replacing mechanism to the position where the full-charge battery is arranged, grabbing the full-charge battery by the grabbing mechanism, moving the battery replacing mechanism to the position opposite to the vehicle to be replaced, moving and extending the supporting arm 11 of the battery replacing mechanism, and enabling the grabbing mechanism to drive the battery to move to the battery position of the vehicle to be replaced so as to realize the battery replacing operation.

The above-described embodiments of the apparatus are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
