The staggered shaft type fan-shaped unfolding mechanism comprises a staggered shaft supporting rod mechanism. The staggered shaft supporting rod mechanism comprises a plurality of single-hole supporting rods, fixing pieces and shaft ring type connecting assemblies. The plurality of single-hole supporting rods are assembled through the shaft ring type connecting assemblies to form a layered and staggered layout form of the plurality of single-hole supporting rods; the fixing piece is connected with an assembly of the single-hole supporting rod and the shaft ring type connecting assembly. The staggered shaft type fan-shaped unfolding mechanism disclosed by the invention has smaller folding volume and higher axial rigidity, and solves the problems of large size envelope of a supporting rod in a fan-shaped solar wing unfolding mechanism and low rigidity of a rotating shaft.
本发明的交错轴式扇形展开机构包括交错轴撑杆机构,所述交错轴撑杆机构包括若干单孔撑杆、固定件和轴环形式连接组件;若干单孔撑杆通过轴环形式连接组件组装,构成若干单孔撑杆分层交错布局的形式;固定件与单孔撑杆和轴环形式连接组件的组装体连接。本发明的交错轴式扇形展开机构具有更小的收拢体积,更高的轴向刚度,解决了扇形太阳翼展开机构内部撑杆尺寸包络大,回转轴刚度低的问题。
