A telescopic hinge type multi-configuration variable space folding and unfolding mechanism comprises a base, a frame connecting rod, a swing rod, a connecting hinge, a two-degree-of-freedom composite hinge I, a two-degree-of-freedom composite hinge, a secondary telescopic lever and a composite hinge connector. A plurality of configuration states such as a cuboid, a tetrahedron, a pentahedron, a rectangular pyramid, a folding state and a plane state can be obtained through motion changes of the rod pieces, and the folding mechanism has the advantages of being large in folding ratio, high in reliability, high in stability, simple in space folding and the like and can be applied to the fields of spacecraft basic frameworks, large-diameter folding and unfolding antennas, large solar panel supports and the like. And the method has relatively high adaptability and practicability.

    一种伸缩铰链式多构态可变空间折展机构,包括基座、连架杆、摆杆、连接铰链、两自由度复合铰链一、两自由度复合铰链、二级伸缩杠、复合铰链接头,本发明的多构态可变空间折展机构,能够通过杆件的运动变化得到长方体、四面体、五面体、四棱锥、折叠状态和平面状态等多个构态,具有折叠比大、可靠性高、稳定性强、空间折叠简单等特点,可应用于航天器基础骨架、大口径折展天线、大型太阳帆板支架等领域,具有较强的适应性和实用性。
