[0026] When the RGV sorting trolley needs to move along the X-axis: by starting the first drive motor 14, the first drive motor 14 drives the first active pulley 16 to rotate, and the first active pulley 16 is connected to the first driven pulley 17 by the first belt 19, so that the first driven pulley 17 can be synchronously driven to rotate, and when the first driven pulley 17 rotates, it can drive the first transmission shaft 18 to rotate, and when the first transmission shaft 18 rotates, it can drive the first driving wheel 12 to rotate, and when the first driving wheel 12 rotates, the RGV sorting trolley can realize the need for X-axis movement.

[0027] It should be noted that when moving on both sides of the X-axis direction, the first drive motor 14 can be adjusted to rotate forward or reverse. Through the above transmission method, when the first drive motor 14 rotates forward, the first transmission shaft 18 can rotate forward, so that the first driving wheel 12 can move to one side of the X-axis direction;

[0028] Conversely, when the first driving motor 14 is reversed, the first transmission shaft 18 can be reversely rotated, so that the first driving wheel 12 can be moved to the other side of the X-axis direction, thereby realizing the movement operation on both sides of the X-axis direction.
