An opening is provided at the top of the vehicle body, and the roof panel is positioned at the opening. It also includes a support device, a flexible fabric, two sets of bases, and two sets of gas springs. The top of the flexible fabric is connected to the bottom of the roof panel, and the bottom of the flexible fabric is connected to the top of the vehicle body, with the flexible fabric communicating with the opening at the top of the vehicle body. The two sets of bases are respectively installed on the left and right sides of the top of the vehicle body. The tops of the two sets of gas springs are rotatably connected to the two sets of bases, and the tops of both sets of gas springs are rotatably connected to the inner sidewall of the roof panel. The support device is symmetrically arranged on the left and right sides of the vehicle body and is used to support the roof panel. The rear lifting and moving mechanism allows personnel to manually move the top plate upwards, causing the two sets of gas springs to extend. Once extended, the gas springs support and fix the top plate in place. Simultaneously, the upward movement of the top plate causes the support device to unfold, supporting the rear of the top plate and raising it at an inclined angle. When it is necessary to lower the top plate, personnel can manually move it downwards, compressing the two sets of gas springs. This causes the gas springs to move the top plate downwards, at which point the top plate and support device fold and store, improving the reliability of the lifting and moving mechanism and reducing the complexity of the lifting structure.

The first support arm and the fourth support arm are rotatably connected in a cross configuration. After the top plate moves upward, it drives the second fixed seat to move upward, which in turn drives the top ends of the second and fourth support arms to move upward. This allows the first, second, third, and fourth support arms to work together to support the rear of the top plate, improving the stability of the top plate during lifting and lowering.

[0008] Preferably, it also includes a pull rope, which is installed on the inner wall of the roof panel; by setting up the pull rope, when personnel need to move the roof panel downward, they can pull the pull rope to move the roof panel downward, thereby improving the ease of operation of lowering the roof panel.

[0009] Preferably, it also includes a zipper, which is set on the flexible fabric; by setting the zipper, it is easy to open the lower part of the flexible fabric, thereby improving the convenience of ventilation of the flexible fabric.

[0010] Preferably, it also includes a transparent window, which is set on the outer wall of the flexible fabric; by setting the transparent window, the light transmission effect of the flexible fabric is improved.

[0011] Preferably, it also includes a first mesh and a second mesh, with the first mesh disposed on the upper part of the outer wall of the flexible fabric and the second mesh disposed on both sides of the outer wall of the flexible fabric; by setting the first mesh and the second mesh, the ventilation effect of the flexible fabric is improved.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: personnel can manually move the top plate upward, causing the top plate to drive the two sets of gas springs to extend. After the two sets of gas springs extend to their positions, they support and fix the top plate. At the same time, the upward movement of the top plate causes the support device to unfold, so that the support device supports the rear of the top plate, causing the top plate to rise at an inclined angle. When it is necessary to lower the top plate, personnel can manually move the top plate downward, causing the top plate to compress the two sets of gas springs. This causes the two sets of gas springs to drive the top plate downward. At this time, the top plate and the support device fold and store, improving the reliability of the lifting and moving of the top plate and reducing the complexity of the lifting structure.
