The operation is simple and convenient, and it is more convenient for young children to assemble the vehicle body. The connecting shaft 40 is connected to the vehicle body 50 so that the wheel body 10 can rotate relative to the connecting shaft 40. The wheel body 10 can form a passive wheel. After the connecting shaft is plugged into the vehicle body, the vehicle body can be pushed to move, which is simple to operate.
[0044] Further, such as Figures 6 to 13As shown, the wheel hub 30 includes a hub cover and a hub shaft. The hub shaft is connected to the side of the hub cover facing the connecting shaft 40.

[0045] As one embodiment, Figure 7 and Figure 9 As shown, the hub groove and the tight-fitting shaft 41 are respectively in a cross shape, which increases the contact area between the tight-fitting shaft 41 and the hub groove and improves the connection stability between the hub groove and the tight-fitting shaft 41.
[0046] Further, such as Figures 2 to 3 and Figures 6 to 13 As shown, the wheel body 10 further includes a motor transmission member 20, with a transmission connection cavity 21 and a motor plug-in portion 24 for transmission connection with the motor 52 at each end. The inner wall of the transmission connection cavity 21 is provided with a transmission bar 22 and a first limiting portion 23. The transmission bar 22 protrudes from the inner wall of the transmission connection cavity 21. The wheel body 10 is connected to a transmission boss 11 on the side facing the motor transmission member 20. The outer peripheral wall of the transmission boss 11 is provided with a transmission groove 13 and a second limiting portion 14.

The wheel body 10 is connected to the transmission boss 11. The wheel body 10 is mounted in the transmission connection cavity 21 via the transmission boss 11 to achieve transmission connection with the motor transmission member 20. A transmission bar 22 and a first limiting portion 23 are provided within the transmission connection cavity 21. A transmission groove 13 and a second limiting portion 14 are provided on the outer peripheral wall of the transmission boss 11. The transmission bar 22 is inserted into the transmission groove 13 to limit the circumferential assembly position of the motor transmission member 20 and the wheel body 10, thereby driving the wheel body 10 to rotate. The first limiting portion 23 and the second limiting portion 14 extend circumferentially and engage with each other, limiting the axial position of the wheel body 10 and the motor transmission member 20, preventing the wheel body 10 and the motor transmission member 20 from falling off in the axial direction, improving the connection stability between the motor 52 and the wheel body 10, and ensuring the transmission reliability of the motor 52 and the wheel body 10.
[0047] As one embodiment, Figure 5 As shown, the motor plug-in portion 24 is a hole structure, and the transmission shaft is plugged into the motor plug-in portion 24. As one embodiment, the shape of the motor plug-in portion 24 corresponds to the shape of the transmission shaft of the motor 52. As one embodiment, the motor plug-in portion 24 is an elliptical hole.
[0048] Further, such as Figure 8 as well as Figures 16 and 17 As shown, the connecting shaft 40 also includes a plug-in assembly 42 for plugging into the vehicle body 50. The plug-in assembly 42 extends away from the tight-fitting shaft 41 and protrudes from the transmission boss 11.

After the connecting shaft 40 is connected to the vehicle body, the connecting shaft 40 and the wheel body 10 can rotate relative to each other, allowing the wheel body 10 to rotate and the vehicle body to move through the wheel body 10. When the wheel body 10 is connected to the motor 52 via the motor transmission member 20, the plug-in assembly 42 is inserted into the transmission connection cavity 21 and received in the receiving cavity 25, without affecting the transmission connection between the wheel body 10 and the motor 52.
[0049] As one embodiment, Figures 16 and 17 As shown, the vehicle body 50 is provided with a plug-in hole 54, and the plug-in unit 42 is plugged into the plug-in hole 54. Figures 8 to 13 As shown, the wheel body 10 includes a wheel plate and a wheel body 18. The wheel body 18 surrounds and is connected to the outer peripheral surface of the wheel plate. The transmission boss 11 is connected to the wheel plate. The center hole 15 is opened in the wheel plate. The connecting shaft 40 also includes a limiting cover 43. The tight-fitting shaft 41 is located in the limiting cover 43. At least a part of the limiting cover 43 is installed in the boss hole 12. The wheel plate is axially located between the limiting cover 43 and the hub cover to limit the axial movement space of the wheel body 10 and improve the rotational stability of the wheel body 10.

The receiving groove 17 is connected to the center hole 15, and the hub cover is mounted in the receiving groove 17. The receiving groove 17 provides a mounting space for the hub cover. The hub cover can rotate relative to the wheel body 10 within the receiving groove 17, thereby improving the assembly stability of the hub cover and the wheel body 10.
[0051] Further, such as Figure 2 and Figure 4 As shown, the transmission groove 13 and the transmission bar 22 extend in the axial direction. The transmission bar 22 is inserted into the transmission groove 13 in the axial direction. The transmission groove 13 has a guiding effect on the assembly of the transmission bar 22, thereby improving the assembly accuracy of the wheel body 10 and the motor transmission member 20.
[0052] Further, such as Figure 2 and Figure 4As shown, the first stopper 23 is located at the end of the transmission connection cavity 21 facing the wheel body 10, and the second stopper 14 is located at the end of the transmission boss 11 away from the motor transmission member 20. After the transmission bar 22 is guided and inserted for a distance through the transmission groove 13, the first stopper 23 and the second stopper 14 are then engaged, improving the accuracy of the plug-in assembly of the wheel body 10 and the motor transmission member 20.
