The corrugated sealed cabin structure with the space capable of being unfolded comprises an end frame, an inner corrugated disc and an outer corrugated disc. Wherein the end frame is of a rotary structure and is provided with two bosses, the inner side boss is in electron beam welding with the inner corrugated disc, and the outer side boss is in electron beam welding with the outer corrugated disc; the space among the end frame, the inner corrugated disc and the outer corrugated disc forms a sealing cavity, in the initial state, the inner corrugated disc and the outer corrugated disc are in a disc state, when compressed gas is inflated, gas pressure enables the inner corrugated disc to expand, and meanwhile the outer corrugated disc is driven to expand and expand to form a conical structure. The invention provides a double-layer sealing structure which is high in compression ratio, large in volume and high in sealing degree, and the double-layer sealing structure is simple in structure, reliable in inflation expansion form and capable of being inflated and expanded on orbit.

    一种空间可展开波纹密封舱结构,包括:端框、内波纹盘和外波纹盘;其中,端框为回转结构,具备两处凸台,内侧凸台与内波纹盘电子束焊接,外侧凸台与外波纹盘进行电子束焊接;端框、内波纹盘、外波纹盘之间的空间形成了密封腔,初始状态,内波纹盘和外波纹盘为圆盘状态,在充入压缩气体时,气体压力使内波纹盘膨胀,同时带动外波纹盘膨胀,展开成锥形结构。本发明提供一种高压缩比、大容积、高密封度的双层密封结构,该结构造型简单、充气展开形式可靠,可进行在轨充气展开。
