The multiple groups of second airbags 7 and the multiple groups of third airbags 8 are interconnected as a whole. The multiple groups of second airbags 7 and the multiple groups of third airbags 8 are arranged on the left and right sides of the side curtain 4. The first airbags 6 and the second airbags 7 are respectively connected to an external air pump, and the multiple groups of third airbags 8 are arranged in the middle of the multiple groups of second airbags 7;

[0022] In this embodiment, when it is necessary to raise the roof of the car 1, the inflatable component 5 is inflated by an external air pump, so that the inflatable component 5 is inflated and supports the top plate 3, thereby causing the front part of the top plate 3 to flip upward. After the top plate 3 is flipped upward, the side curtains 4 are unfolded upward, thereby raising the roof of the car 1. When it is necessary to lower the top plate 3, the air in the inflatable component 5 is extracted by an external air pump. After the inflatable component 5 shrinks, it loses its supporting force, causing the top plate 3 to flip downward and be installed on the top of the car 1, thereby improving the lightness of the lifting structure and reducing the space occupied by the lifting structure inside the car 1. At the same time, the side curtains 4 and the inflatable component 5 are used in conjunction to increase the warmth retention effect.
