The invention provides a space folding and unfolding mechanism based on a hexagonal prism folding and unfolding unit, the upper layer and the lower layer of the hexagonal prism folding and unfolding unit are the same in structure and are in mirror symmetry, the hexagonal prism folding and unfolding unit comprises an inner hexagonal prism assembly and an outer annular truss assembly, and a center faceplate of the inner hexagonal prism assembly is connected with an outer faceplate of the outer annular truss assembly through a center connecting rod; the outer disc chucks of the outer annular truss assembly are sequentially connected through the outer connecting rods and are distributed in a circumferential array mode, the center disc chuck is located at the circle center of a hexagon circumcircle of projection of the outer annular truss assembly, the outer disc chucks are located on the same plane and are parallel to the plane where the center disc chuck is located, and the six sets of outer connecting rods are arranged on the projection plane in a hexagon mode. According to the space folding and unfolding mechanism, the size of the space folding and unfolding mechanism is changed by adjusting the length of the center connecting rod and the outer connecting rod and the number of the hexagonal prism folding and unfolding units, unfolding or folding can be achieved only through one drive, and the space folding and unfolding mechanism has the advantages of being large in folding and unfolding ratio, high in stability, large in rigidity and the like and can meet various aviation task requirements.

    本发明提供一种基于六棱柱折展单元的空间折展机构,六棱柱折展单元的上下层结构相同且镜像对称,其包括内六棱柱组件和外环形桁架组件,内六棱柱组件的中心花盘通过中心连杆与外环形桁架组件的外花盘连接,外环形桁架组件的外花盘间通过外连杆依次连接并呈圆周阵列分布,中心花盘位于外环形桁架组件投影的六边形外接圆圆心,外花盘均处于同一平面且与中心花盘所在平面相互平行,六组外连杆在投影面上呈六边形布置,本发明空间折展机构通过调节中心连杆、外连杆的长度及六棱柱折展单元的数量改变构成空间折展机构的大小,仅需一个驱动即可实现展开或收拢,具有折展比大、稳定性高、和刚度大等优点,能够满足多种航空任务需求。
