[0037] The driving wheel assembly includes a driving shaft 8, a driving wheel 4, a driving motor 5, a battery module 6 and a control module 7; the steering wheel group includes a steering wheel 9, a steering shaft, a vertical pole 10 and a handlebar 11; the driving wheel 4 is arranged on the side of the first long side close to the first short side, and the steering wheel 9 is arranged on the side of the first long side close to the second short side. When the luggage is placed on the ground with one side of the first long side, the luggage contacts the ground through the steering wheel 9 and the driving wheel 4 and rolls.

[0038] The driving wheel 4 is fixedly connected to the driving shaft 8, and the driving shaft 8 is freely rotatably arranged on the riding base through a shaft frame and a bearing. The driving shaft 8 is transmission-connected to the driving motor 5, and the control module 7 is connected to the driving motor 5 to control the operation of the driving motor 5. The battery module 6 supplies power to the driving motor 5.

[0039] The steering wheel 9 is freely rotatably arranged on the bottom end of the upright pole 10 through the steering shaft, bearing and shaft frame. The upright pole 10 is freely rotatably and axially limitedly connected to the riding base 3, specifically: a column tube 12 is fixedly arranged on the side of the second short side, and the upright pole 10 is matched and sleeved in the column tube 12, which can be freely rotatable and axially limited. The column tube 12 is fixedly connected to the riding base 3, and a triangular reinforcing rib 13 is also arranged between the column tube 12 and the riding base 3, which is respectively fixedly connected to the column tube 12 and the riding base 3 to ensure the stability of the riding base 3 and the upright pole 10.

[0040] A handlebar 11 is provided at the top of the vertical pole 10, and the user can rotate the vertical pole through the handlebar 11 to adjust the direction of the steering wheel 9, so that the user can flexibly control the direction of travel during electric riding.
