The invention discloses an expandable supporting structure of a derail sail device based on Kresling paper folding. The expandable supporting structure comprises a paper folding deformation mechanism, a paper folding driver, a parallelogram rod group and a shear fork hinge rod group, the paper folding deformation mechanism comprises a crease connecting rod, an upper end plate and a lower end plate; the two ends of the paper folding driver are connected with the upper end plate and the lower end plate correspondingly, the axial extension of the paper folding driver is changed in a gas driving mode, and then the upper end plate of the paper folding deformation mechanism is driven to do spiral motion. The parallelogram rod groups and the shear fork hinge rod groups are annularly arrayed around a central shaft of the paper folding deformation mechanism; two diagonal rotating positions of the parallelogram rod group are respectively connected with the upper end plate and the lower end plate, and two rotating nodes at the end part of the shear fork hinge rod group are connected with the other two free rotating positions in the parallelogram rod group; under the transmission of the parallelogram rod group, the shear fork hinge rod group is unfolded, and finally the film sail surface of the derail sail is dragged to be unfolded. The structure has the advantages of high unfolding and folding ratio, simplicity in driving, high reliability and the like.

    本发明公开了一种基于Kresling折纸的离轨帆装置可展开支撑结构,该结构包括折纸变形机构、折纸驱动器、平行四边形杆组和剪叉铰杆组;折纸变形机构包括折痕连杆、上端板和下端板;折纸驱动器两端分别连接上端板和下端板,采用气驱的方式改变折纸驱动器的轴向伸长,进而带动折纸变形机构的上端板进行螺旋运动;平行四边形杆组和剪叉铰杆组绕着折纸变形机构的中心轴环向阵列排列;平行四边形杆组的两个对角转动位置分别与上端板和下端板连接,剪叉铰杆组端部的两个转动节点与平行四边形杆组中的另外两个自由转动位置连接;在平行四边形杆组的传动下,剪叉铰杆组展开,最终牵引离轨帆薄膜帆面的展开。本发明结构具备展收比高,驱动简单,可靠性高等优点。
