The lower end of the front tube 22 is connected to a steering wheel assembly 4, and the upper end is equipped with a retractable T-handle 21. The T-handle 21 and the front tube 22 can only move axially, not circumferentially. This allows for adjustment of the height of the T-handle 21 during use, improving the user's riding comfort and enhancing the user experience. When the user needs to turn while riding, rotating the T-handle 21 causes the front tube 22 to rotate, which in turn rotates the steering wheel assembly 4 at the lower end of the front tube 22, thus achieving steering.

[0075] In this embodiment, the front tube 22 is disposed inside the cover 23. The front tube 22 and the cover 23 can be fixedly disposed together, or they can rotate relative to each other. When the front tube 22 and the cover 23 can rotate relative to each other, the cover 23 can be fixedly connected to the connecting frame 25. When the front tube 22 and the cover 23 are fixedly disposed, since the steering of the electric luggage case is achieved by rotating the T-handle 21 of the handle assembly 2 and the front tube 22 in conjunction with the steering wheel assembly 4, the handle assembly 2 and the connecting frame 25 need to be rotatably connected to ensure proper connection. The connection point between the handle assembly 2 and the connecting frame 25 can be located on the cover 23 or on the front tube 22, depending on the actual usage. When the front end of the handlebar assembly 2 is rotatably connected to the connecting frame 25, a hole needs to be made in the cover 23 to provide movement space for the cover 23 to rotate with the front tube 22. Moreover, this hole can also serve as a structure to limit the rotation angle of the handlebar assembly 2, thereby improving safety.

[0076] In this embodiment, preferably, the front tube 22 and the cover 23 are fixedly disposed together, which facilitates the assembly of the front tube 22 and the cover 23. However, when the cover 23 and the front tube 22 are fixedly disposed together, the connection structure between the cover 23 and / or the front tube 22 and the connecting frame 25 becomes more complex. Therefore, in this embodiment, as a further preferred implementation, the handlebar assembly 2 can be fixedly connected to the connecting frame 25 through the structure in the steering wheel assembly 4. That is, the handlebar assembly 2 is connected to the sliding member 33 through the cooperation of the steering wheel assembly 4 and the connecting frame 25. The specific implementation method is described in detail below.
