The universal wheel (11) moves downward until it is in contact with the ground. Then, as the universal wheel (11) continues to move downward, the bottom plate (1) is lifted up away from the ground. Step 5: The solar panel (3) is flipped downward along with the mounting frame (2) to be folded. At the same time, the universal wheel (11) moves downward until it is in contact with the ground, and the bottom plate (1) is lifted up away from the ground. That is, the operation of the motor (27) can not only realize the folding and storage of the solar panel (3), but also move the universal wheel (11) downward until it is in contact with the ground, thereby facilitating the transfer of the bracket, achieving two goals at one stroke.
