[0044] The chassis 2 is fixedly mounted above the supporting assembly 10.

[0045] The top frame 4 is located above the chassis 2 and is used to carry the roof tent 100, and the shape and the structure of the roof tent 100 are not limited by the figures. The top frame 4 as shown in the figures is used as a bottom of the roof tent 100 to be integrated with the roof tent 100.

[0046] A lower end of the linear lifting mechanism is relatively fixed to the chassis 2, and an upper end of the linear lifting mechanism is fixed to the top frame 4. The specific shape of the linear lifting mechanism can be determined according to design requirements, and all that is needed is to raise the top frame 4 from the chassis 2 or to descend the top frame 4 on the chassis 2. The linear lifting mechanism rises and falls to drive the top frame 4 to rise to get away from the chassis 2 such that the equipment is in an unfolded state, or to drive the top frame 4 to fall to overlap the chassis 2 such that the equipment is in a folded state.

[0047] The linear lifting mechanism is a scissor type lifting frame 31 in the preferred embodiments as shown in FIG. 1 to FIG. 11. A lower end of the scissor type lifting frame 31 is pivotally connected to lower pivot points A/B of the chassis 2 such that the scissor type lifting frame 31 is fixedly mounted on the chassis 2, an upper end of the scissor type lifting frame 31 is pivotally connected to upper pivot points C/D of the top frame 4 such that the top frame 4 is fixedly mounted on the scissor type lifting frame 31, and thus the top frame 4 is mounted on the chassis 2 by means of the scissor type lifting frame 31 in a rising and falling manner. The scissor type lifting frame 31 as shown in the figures comprises a left scissor structure and a right scissor structure, which can ensure the stable rising and falling of the top frame 4.
