A dragging unfolding type high-rigidity stretching arm with high spatial folding-unfolding ratio comprises a folding and unfolding unit set, an axial force bearing cable, unfolding jet engines and an end face force bearing plate. The two unfolding jet engines are fixed to the two end face force bearing plates respectively, a foldable unit set is arranged between the two end face force bearing plates, the foldable unit set comprises N foldable units hinged in series, and the two foldable units on the outermost side are fixedly connected with the two end face force bearing plates respectively. Each foldable unit is a triangular prism after being unfolded, a telescopic rod is hinged to the opposite angle of each side face of the triangular prism, the telescopic rods stretch out along with unfolding of the foldable units and retract along with folding, and the three axial force bearing cables stretch across the corresponding side faces of the N foldable units respectively and are limited in the radial direction. The two ends of each axial force bearing cable are fixed to the two end face force bearing plates respectively. According to the stretching arm, the rigidity and the tensile capacity are improved, and the dragging and unfolding driving mode is high in efficiency and can adapt to unfolding of the large-scale stretching arm.

    空间高折展比拖拽展开式高刚度伸展臂,包含可折展单元组、轴向承力索、展开喷射发动机和端面承力板;两个展开喷射发动机分别固定在两个端面承力板上,两个端面承力板之间布置有可折展单元组,所述可折展单元组包含串联铰接的N个可折展单元,最外侧的两个可折展单元分别与两个端面承力板固接;每个可折展单元展开后为三棱柱,三棱柱每个侧面的对角铰接有一根可伸缩杆,可伸缩杆随可折展单元的展开而伸长,折叠而收缩,三条轴向承力索分别横跨N个可折展单元对应的侧面,并被径向限位,三条轴向承力索两端分别固定在两个端面承力板上。本发明伸展臂提高了刚度与抗拉能力,拖拽展开驱动方式具有效率高且能适应大尺度伸展臂展开。
