The invention provides a space unfolding variable configuration mechanism and a spacecraft. The space unfolding variable configuration mechanism comprises an air bag; the shape memory structure is connected with the air bag; the shape memory structure comprises a combination part and a branch part extending outwards from the combination part; the branch part comprises a connecting piece and a plurality of supporting pieces which are sequentially connected through the connecting piece; the connecting piece is made of a shape memory polymer material; the shape memory structure comprises a folded state and an unfolded state; the connecting piece can be subjected to phase change through temperature adjustment, so that the shape memory structure is in a folded state or an unfolded state; when the shape memory structure is in the storage state, the air bag is stored in a space defined by the shape memory structure; when the shape memory structure is in the unfolded state, the air bag is completely unfolded along with the shape memory structure. The space unfolding variable configuration mechanism can solve the problem that the structure, the shape and the posture of a spacecraft are difficult to regulate and control due to the fact that the unfolding speed is too high in vacuum.
本发明提供一种空间展开变构型机构及航天器,该空间展开变构型机构包括气囊;以及与气囊连接的形状记忆结构;所述形状记忆结构包括结合部以及由结合部向外延伸出的分支部;所述分支部包括连接件以及通过连接件依次连接的若干支撑件;所述连接件材质为形状记忆聚合物材料;所述形状记忆结构包括收纳状态和展开状态;通过温度调节可使得连接件发生相变使得形状记忆结构处于收纳状态或展开状态;当形状记忆结构处于收纳状态,所述气囊收纳于形状记忆结构围合形成的空间内;当形状记忆结构处于展开状态,所述气囊随形状记忆结构完全展开。该空间展开变构型机构能够解决真空中展开速度过快导致的航天器结构、形状、姿态难以调控的问题。
