The two steering sleeves 625 are spaced apart in the second direction, each steering sleeve 625 is located on the side of the corresponding positioning sleeve 621 facing away from the other positioning sleeve 621, and each steering sleeve 625 is spaced apart from the corresponding positioning sleeve 621 and the ball-head rod 623 in the second direction. Each steering sleeve 625 is sleeved on the corresponding connection sleeve 624, the connection sleeve 624 penetrates through the corresponding steering sleeve 625, and the connection sleeve 624 is rotatably connected to the corresponding steering sleeve 625. The end of the connection sleeve 624 away from the corresponding positioning sleeve 621 extends out of the corresponding steering sleeve 625 and is fixedly connected to the corresponding first wheel 20. Thus, when the first connection rod 622 and the two positioning sleeves 621 rotate, the two ball-head rods 623, the two connection sleeves 624 and the two first wheels 20 may rotate synchronously.

In some embodiments, each steering sleeve 625 may include a sleeve body 6251, a first protruding shaft 6252, a second protruding shaft 6253 and an extension rod 6254. The sleeve body 6251 is annular and is sleeved on the corresponding connection sleeve 624. The first protruding shaft 6252 and the second protruding shaft 6253 protrude from a peripheral wall of the sleeve body 6251, and the first protruding shaft 6252 is spaced apart from the second protruding shaft 6253 in a circumferential direction of the sleeve body 6251. The first protruding shaft 6252 penetrates through the first end portion 11 in the third direction and is rotatably connected to the first end portion 11. The second protruding shaft 6253 penetrates through the first end cover 41 in the third direction and is rotatably connected to the first end cover 41.

When the first wheels 20 and the driving shaft rotate around central axes of the first wheels 20, the ball-head rods 623 and the steering sleeves 625 may rotate synchronously around central axes with axial directions coinciding with the third direction. In addition, when rotation angles are large, the connection sleeves 624 may be driven to turn around synchronously to drive the first wheels 20 to turn around synchronously, thereby achieving turning of the first wheels 20.

The driving shaft formed by fitting the positioning sleeves 621, the ball-head rods 623 and the connection sleeves 624 may transmit steering power to the first wheels 20 to turn the first wheels 20 when transmitting traveling power to the first wheels 20 to rotate the first wheels 20.

Thus, the situation that the structures for turning the toy car 100 are stacked on the chassis 10 in the third direction may be avoided, the height of the toy car 100 may be reduced, and the stability of the toy car 100 during traveling may be improved. At the same time, when a worker designs the toy car 100 by scaling down a car according to the actual size of the car, the situation that the structures in the toy car 100 are stacked in the third direction is reduced, so that the lower limit of the height of the toy car 100 in the third direction may be reduced, and the worker can design the toy car 100 in the smaller scale. For example, when the worker designs the toy car 100 provided in the embodiments of the present application by scaling down the car according to the actual size of the car, the ratio of the size of the toy car 100 to the actual size of the car may be greater than or equal to 1:43.

The arch portion 731 is arranged around the first positioning platform 14, and the arch portion 731 shields a part of the first positioning platform 14 from one side in the third direction and two sides in the second direction. Outer walls of two sides of the arch portion 731 in the second direction may abut against the first positioning platform 14, and the first positioning platform 14 may limit the movement of the arch portion 731 in the second direction. The support portion 732 protrudes from the arch portion 731 in the third direction and is spaced apart from the first positioning platform 14 in the third direction.

For another example, the notch 7321 may be an O-shaped opening, and the notch 7321 does not penetrate through the support portion 732 in a direction (for example, the second direction and the third direction) perpendicular to the first direction.

It can be understood that when the second driving member 71 drives the eccentric member 72 to rotate, the end of the eccentric member 72 connected to the support portion 732 moves in a circumferential direction. The eccentric member 72 may push the steering frame 73 to move in the second direction, and at the same time, the end of the eccentric member 72 connected to the support portion 732 rotates in the notch 7321 and moves in the third direction.
