A fixing part and a folding part are arranged in the cabin.

The hydraulic folding member includes a lifting lug 20 and a hydraulic telescopic rod 23. The inner wall of the cabin and the fixed part and the folding part are all provided with a lifting lug 20. One end of the lifting lug 20 is connected to the connecting end plate 22 of the cabin body. The connecting end plate 22 of the cabin body is connected to the inner wall of the cabin, the other end of the lifting lug 20 is connected to the connecting ring 21, the telescopic end and the fixed end of the hydraulic telescopic rod 23 are connected with installation hooks, and the telescopic end of the hydraulic telescopic rod 23 The installation hook is connected to the connecting ring 21 at the folded portion, and the installation hook at the fixed end of the hydraulic telescopic rod 23 is connected to the connecting ring 21 at the fixed portion.

The arrangement direction of the hydraulic telescopic rod 23 is parallel to the axial direction of the cabin body.

At the air-filling place of the cabin, air locks are arranged on the pipeline, and vent holes are provided on the cabin; the gas in the gas storage room will be carried from the earth to space, and considering the activity and relative molecular mass of the gas, priority is given to Nitrogen is selected; the air outlet directions of the vent holes on the same circumference of the cabin body are opposite; the vent holes on both sides of the cabin body are parallel to each other, and the outlets are opposite, which is convenient for exhausting, and secondly, it can pressurize the cabin to make the gas spray come out, create a centripetal force to drive the structure to rotate, and apply an initial rotational force;

The cabin body of the space capsule is in a folded state before reaching the predetermined orbit. Later, with the space capsule in place, the pneumatic device inside the space capsule will inflate and replenish the cabin according to its on-orbit situation. The air pump and vent hole are operated in conjunction with the pressure gauge in the cabin when inflated. As shown in Figure 1 and Figure 4 when deployed, the space capsule after inflation is approximately an ellipsoid, and the interior of the space capsule is flexible and expandable. The in-plane stress generated on the surface of the cabin is sufficient to make the cabin resist the deformation of external force;

In order to buffer the impact and reduce the stress concentration, and supplemented by the support of the hydraulic telescopic rod 23 in the cabin, it can be rigidified without additional means, and the flexible cabin body has a certain rigidity. The hydraulic telescopic rod 23 can be adjusted according to the size of the cabin.

In the past, the space capsule mainly used solar panels to supply power to the equipment. Angle adjustment undoubtedly increases the mechanical complexity of the space capsule. In the design and structure of the space capsule, since the space capsule generally has a nearly circular appearance, a flexible film is directly pasted on the surface of the space capsule to generate electricity, which can realize omnidirectional solar power generation. Improving the power generation efficiency can reduce the mechanical complexity and operation difficulty, and reduce the complexity of the mechanical structure of the solar power generation device.
