The invention discloses a rope-driven unfolding truss module for on-orbit assembly, belongs to the technical field of space folding and unfolding mechanisms, and can solve the problems of large-scale development of a space folding and unfolding mechanism structure and limitation of the volume of a carrying tool. The truss mechanism comprises a plurality of folding units, the adjacent folding units are arranged front and back and connected through rotating pairs, and two ropes start from the same vertex of the folding unit on the outermost side, are connected with rod pieces in the folding units in series and finally reach diagonal vertexes; one ends of the two ropes are connected with the power element, the other ends of the two ropes are fixed to the vertexes of the opposite angles, and folding and unfolding of the truss are achieved by controlling the telescopic rods through the ropes.

    本发明公开了一种用于在轨组装的绳驱展开桁架模块,属于空间折展机构技术领域,能够解决空间折展机构结构大型化发展与运载工具容积的限制的问题。本发明桁架机构包括若干个折叠单元,相邻折叠单元前后排列通过转动副连接,两条绳索从最外侧折叠单元的同一顶点出发,分别串联各折叠单元中的杆件,最后到达对角顶点;两条绳索的一端均与动力元件连接,另一端固定于对角顶点,通过绳索控制伸缩杆来实现桁架的折叠与展开。
