The invention belongs to the field of spaceflight folding and unfolding mechanisms, and particularly relates to an accordion type space unfolding mechanism which is characterized in that unfolding rib rod sets are arranged on the two sides of a fixed rib rod set, the fixed rib rod set and the unfolding rib rod sets share transition rib rods A, transition rib rods B are arranged at the two ends of the outermost side, and root rib rods of the fixed rib rod and the transition rib rods A are connected through root fixing beams; root rib rods of the unfolding rib rods, the transition rib rods A and the transition rib rods B are connected through root unfolding beams, and hinges for hinging middle rib rods and end rib rods of the fixed rib rods and the transition rib rods A are connected through middle fixed beams. The hinged positions of the middle rib rods and the end rib rods of the unfolding rib rods, the transition rib rods A and the transition rib rods B are connected through middle unfolding beams, and the end rib rods of the fixed rib rods and the transition rib rods A are connected through end fixing beams. The fixing rib rod set and the unfolding rib rod set are used in a combined mode, and the requirements for light weight, high rigidity and large size can be met.

    本发明属于航天折展机构领域,具体地说是一种手风琴式空间展开机构,固定筋杆组的两侧均设有展开筋杆组,固定筋杆组与展开筋杆组共用过渡筋杆A,位于最外侧的两端为过渡筋杆B,固定筋杆及过渡筋杆A的根部筋杆通过根部固定梁相连,展开筋杆、过渡筋杆A及过渡筋杆B的根部筋杆之间通过根部展开梁相连,固定筋杆及过渡筋杆A的中部筋杆与端部筋杆铰接的铰链之间通过中部固定梁相连,展开筋杆、过渡筋杆A及过渡筋杆B的中部筋杆与端部筋杆的铰接处通过中部展开梁相连,固定筋杆及过渡筋杆A的端部筋杆之间通过端部固定梁相连。本发明将固定筋杆组与展开筋杆组组合使用,可满足轻质化、高刚度、大型化的要求。
