The invention discloses a semi-rigid sleeve type inflatable unfolding sealed cabin capable of freely stretching and retracting, and belongs to the technical field of spacecraft structures. The sealed cabin comprises a rigid protective shell, a flexible bag body and an inflation system. The rigid protective shell is of a step-by-step nested multi-section sleeve structure, a flexible bag body is arranged in the rigid protective shell and can be inflated and unfolded into various shapes from a folded state according to needs, the flexible bag body is connected with the rigid protective shell through a plurality of connecting belts, and the inflation system is installed on the inner surface of the end of the rigid protective shell and inflates the flexible bag body. The problems that a rigid cabin is large in launching size, large in weight, small in internal effective space and incapable of being folded are effectively solved, and the problems that an inflatable cabin is difficult to fold due to the fact that the cabin wall is too thick, materials are prone to being folded and damaged, and unfolding control is difficult are effectively solved. The rigid sleeve structure solves the problems that a full-flexible sealed cabin structure is small in rigidity, collapsing deformation is prone to being caused after air leakage, and the like, and safety of personnel and equipment in the cabin is further guaranteed.

    一种可自由伸缩的半刚性套筒式充气展开密封舱,属于航天器结构技术领域。该密封舱,包括刚性防护外壳、柔性囊体及充气系统;刚性防护外壳采用逐级嵌套的多节套筒结构,刚性防护外壳内部设有柔性囊体,根据需要可由折叠状态充气展开为多种形状,柔性囊体通过多个连接带与刚性防护外壳连接,充气系统安装在刚性防护外壳的端部内表面上,并为柔性囊体充气。本发明有效解决了刚性舱发射体积大、重量大、内部有效空间小、不能折叠的问题,以及充气舱由于舱壁太厚造成的难以折叠、易造成材料折叠损伤、展开控制难度大等问题。刚性套筒结构解决了全柔性密封舱结构刚度小、漏气后易导致溃缩变形等问题,进一步保证其内部人员、设备的安全。
