Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Such as Figure 1-13 As shown, the present invention includes an airlock chamber 1, a cabin stem and a flexible shell 5, the cabin stem is set in the flexible shell 5, the airlock 1 is arranged at the upper end of the cabin stem, and the upper side of the flexible shell 5 is sleeved on the The airlock chamber 1 is connected to one end of the cabin stem, and a bottom flange 8 is provided at the lower end of the cabin stem, and the lower side of the flexible shell 5 is set on the bottom flange 8, as Figure 13 As shown, the flexible shell 5 can be folded along the core column of the cabin to reduce the volume before the cabin is launched, and can be unfolded when it is inflated. Such as Figure 1~2As shown, the cabin core column includes a core column frame 7, an upper end layer, an intermediate layer 3 and a lower end layer, and the upper end layer, t...

Abstract

The invention relates to the technical field of space capsules, in particular to a space inflatable unfolded cabin. The cabin comprises an air brake cabin, a cabin core column and a flexible shell, the cabin core column is arranged in the flexible shell, the air brake cabin is arranged at the upper end of the cabin core column and arranged on the outer side of the flexible shell, and the flexibleshell is unfolded after being inflated; the cabin core column comprises a core column frame which is provided with an upper end layer, a middle layer and a lower end layer in sequence, the upper end layer and the lower end layer are each internally provided with an end layer plate component, a middle layer plate component is arranged in the middle layer, a space expansion component is arranged onthe outer side of the cabin core column, and provided with multiple expansion boards, expansion support rods are arranged between the adjacent expansion boards, a driving unfolding mechanism is arranged in the core column frame, the expansion support rods are driven by the driving unfolding mechanism to sway and unfold or fold the expansion boards. The cabin has the advantages of being foldable, small in mass, low in manufacturing cost, good in protective property and the like, and the cabin has a wide application prospect in the field of deep space exploration.

Description

technical field [0001] The invention relates to the technical field of space capsules, in particular to a space inflatable deployment cabin section. Background technique [0002] In the existing technology, most of the orbiting spacecraft including the International Space Station are made of rigid metal cabins. Rigid metal airtight cabins have disadvantages such as heavy mass, large volume, high launch cost, and difficulty in on-orbit assembly. In addition, due to the limitation of the envelope size of the launch vehicle, the traditional rigid metal airtight cabin must be designed relatively compact, which results in a narrow effective space in the cabin, making it difficult for many scientific experiments to be carried out smoothly, and it is difficult to meet the needs of future deep space exploration development. . Contents of the invention [0003] The object of the present invention is to provide a space inflatable unfolding cabin section, which has the advantages of...
