before a vehicle to be changed drives into the supporting platform 2, the image pickup device shoots a license plate of the vehicle to be changed and sends a license plate picture to the control device, the control device obtains vehicle type parameters (such as the wheel track, the wheel base, the battery model and the like of the vehicle) of the vehicle according to the license plate number, then the control device controls the front wheel positioning device to work according to the vehicle type parameters, in the front wheel positioning device, the driving mechanism 13 drives the first supporting piece 12 to move to a corresponding position along the front-back direction of the vehicle, and then the two first driving structures 141 drive the two blocking structures 142 to move back and forth to the corresponding position along the left-right direction of the vehicle; then, when the vehicle to be changed runs along the channel between the first guide mechanism 41 and the second guide mechanism 42 until the front wheels of the vehicle abut against the blocking structure 142 of the front wheel positioning device, the vehicle to be changed stops running; then, in the rear wheel positioning device, the two first driving structures 141 respectively drive the two blocking structures 142 to move back and forth to corresponding positions along the left and right directions of the vehicle, and the driving mechanism 13 drives the first support 12 to move along the front and rear directions of the vehicle to enable the blocking structures 142 to abut against the rear wheels of the vehicle, so that the electric vehicle to be replaced is positioned in the front and rear directions of the vehicle; then, the control device controls the second positioning mechanisms 15 in the two wheel positioning devices 1 to work simultaneously, and the two second driving structures 151 in each wheel positioning device 1 respectively drive the two pushing pieces 152 to move back and forth along the left and right directions of the vehicle so as to translate the vehicle to be switched to a corresponding position along the left and right directions of the vehicle, so as to position the vehicle to be switched in the left and right directions of the vehicle; the battery installation position of the vehicle to be replaced is limited right above the battery replacement window 21, and the battery of the vehicle to be replaced can be replaced through the battery replacement window 21; after the battery is replaced, in each wheel alignment device 1, the two first driving structures 141 respectively drive the two blocking structures 142 to move in opposite directions along the left and right directions of the vehicle, so that the blocking structures 142 are restored to the original positions; the two second driving structures 151 respectively drive the two pushing members 152 to move back and forth along the left and right directions of the vehicle, so that the pushing members 152 are restored to the original positions; the vehicle is released from the limit, and the vehicle can automatically run out of the supporting platform 2.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
