The invention relates to the technical field of folding structures, in particular to a modular large two-dimensional plane folding and unfolding mechanism which comprises antenna panel units, panel folding and unfolding assemblies, panel folding and unfolding linkage assemblies and panel folding and unfolding power assemblies, the multiple antenna panel units are transversely arranged at intervals, the panel folding and unfolding assemblies are arranged on the surfaces of the antenna panel units, and the panel folding and unfolding linkage assemblies are arranged on the surfaces of the panel folding and unfolding assemblies. The antenna panel units are driven by the panel folding and unfolding assemblies, the panel folding and unfolding linkage assemblies are connected between the two adjacent panel folding and unfolding assemblies, the two adjacent panel folding and unfolding assemblies conduct linkage folding and unfolding through the panel folding and unfolding linkage assemblies, and the panel folding and unfolding power assemblies are arranged on the surface of the satellite body. The other end of the panel folding and unfolding power assembly is connected with the panel folding and unfolding assembly close to the side edge of a satellite, the antenna panel unit has a large folding and unfolding ratio, the space of a rocket fairing is fully utilized, high-efficiency two-dimensional folding and unfolding of the large-size panel satellite antenna are achieved, only one-time movement is needed in the unfolding process, the folding rate is large, and the unfolding state rigidity is large.

    本发明涉及折叠结构技术领域,具体涉及一种模块化大型二维平面折展机构,包括天线面板单元、面板收展组件、面板收展联动组件和面板收展动力组件,若干组所述天线面板单元横向间隔排布,所述面板收展组件设置于天线面板单元表面,所述天线面板单元受面板收展组件的驱动,所述面板收展联动组件连接于相邻两组面板收展组件之间,相邻两组面板收展组件通过面板收展联动组件进行联动收展,所述面板收展动力组件设置于卫星主体表面,所述面板收展动力组件的另一端与靠近卫星侧边的面板收展组件连接,天线面板单元具有大的折展比,充分利用了火箭整流罩的空间,实现大尺寸平板卫星天线的高效率二维折展,展开过程只需一次运动,收拢率大展开态刚度大。
