On the basis of embodiment 4, as shown in fig. 13, the automobile wheel further includes a rolling assembly 9, the rolling assembly 9 is rotatably connected to the arc-shaped frame 38, the rolling assembly 9 is used for facilitating the automobile wheel to move onto the arc-shaped frame 38, the rolling assembly 9 includes a transmission shaft 91 and an arc-shaped belt 92, the two transmission shafts 91 are rotatably connected to the arc-shaped frame 38, the arc-shaped belt 92 is jointly and drivingly connected to the two transmission shafts 91, and the arc-shaped belt 92 is used for reducing friction between the arc-shaped frame 38 and the automobile wheel.

When the automobile is moved to the arc-shaped frame 38, the automobile wheels can drive the arc-shaped belt 92 to rotate, and the arc-shaped belt 92 drives the transmission shaft 91 to rotate, so that the friction between the arc-shaped frame 38 and the automobile wheels is reduced, and the automobile wheels can be conveniently moved to the arc-shaped frame 38.

Example 6

On the basis of embodiment 5, as shown in fig. 1 and 13, the automobile seat further comprises a wedge-shaped mounting block 10, the wedge-shaped mounting block 10 is welded at the front end of the arc-shaped frame 38, and the wedge-shaped mounting block 10 is used for facilitating the automobile to be smoothly moved onto the arc-shaped frame 38.

Wedge-shaped mounting block 10 can guide the automobile wheel, helps the automobile smoothly be moved to curved frame 38.
