The invention discloses a space deployable prism unit for on-orbit assembly. The space deployable prism unit comprises a synchronizing mechanism, an inner cross rod, an outer vertical rod and a central vertical rod, a plurality of synchronizing mechanisms are connected end to end to form an upper ring and a lower ring, the adjacent synchronizing mechanisms in the same ring are folded, unfolded andlimited through connected volute spring hinges, the two rings are connected through outer vertical rods rotationally connected with the synchronizing mechanisms to form a regular hexagonal prism unit, and a center vertical rod is arranged in the center of the regular hexagonal prism unit. The central vertical rod is rotatably connected with the synchronizing mechanisms through foldable inner transverse rods to form a regular hexagonal prism folding and unfolding unit, the three synchronizing mechanisms arranged in the upper ring at intervals are connected with the two obliquely-opposite synchronizing mechanisms in the lower ring through inhaul cables respectively, and the three synchronizing mechanisms arranged in the upper ring at intervals are connected with the lower end of the centralvertical rod through inhaul cables. The deployable prism units are large in folding-unfolding ratio, good in force bearing performance, reliable, stable and good in symmetry, and the connecting rigidity of on-orbit butt joint of the space structure assembling unit can be improved.
一种用于在轨组装的空间可展棱柱单元,它包括同步机构、内横杆、外竖杆和中心竖杆;多个同步机构首尾相接组成上下两个环,同一个环中相邻的同步机构由相连的涡簧铰链折展限位,两个环通过与同步机构转动连接的外竖杆连接组成正六棱柱单元,正六棱柱单元的中心设置有中心竖杆,中心竖杆通过可折展的内横杆与同步机构转动连接形成正六棱柱折展单元,上环中相间的设置的三个同步机构各自分别与下环中斜对的两个同步机构通过拉索连接,上环中相间设置的三个同步机构通过拉索与中心竖杆的下端连接。本发明可展棱柱单元折展比大,承力性能好,可靠稳定,对称性好,有利于提高空间结构组装单元的在轨对接的连接刚度。
