The invention discloses a high-folding-unfolding-ratio cylindrical surface unfolding and folding mechanism with a solid reflecting surface. The high-folding-unfolding-ratio cylindrical surface unfolding and folding mechanism comprises a center panel unfolding and folding mechanism, a radial unfolding and folding mechanism, a left side panel unfolding and folding mechanism and a right side panel unfolding and folding mechanism. The central panel unfolding and folding mechanism is composed of shear fork type units, and axial stretching movement can be achieved. The left side panel unfolding and folding mechanism and the right side panel unfolding and folding mechanism are symmetrically distributed relative to the center panel unfolding and folding mechanism, the radial unfolding and folding mechanisms are installed at the two ends respectively, and the radial unfolding and folding mechanisms are connected with bases at the two ends of the center panel unfolding and folding mechanism. The left and right side panel unfolding and folding mechanisms have the degree of freedom of 1 and synchronously move in the radial direction and the axial direction; in the complete unfolding process, a curved surface formed by the left side panel unfolding and folding mechanism and the right side panel unfolding and folding mechanism can be an appointed paraboloid, a cylindrical surface and other cylindrical surfaces, and in the complete folding process, all the panels are compactly folded, and the size is reduced. And the designed unfolding and folding mechanism is used as a basic unit, axial expansion is carried out, and the unfolding and folding mechanism with a larger size can be expanded.
本发明公开一种具有固体反射面的高折展比柱面可展收机构,包括中心面板展收机构、径向展收机构、左侧面板展收机构、右侧面板展收机构。中心面板展收机构由剪叉式单元组成,可以实现轴向的伸展运动。左侧面板展收机构、右侧面板展收机构关于中心面板展收机构对称分布,两端分别安装径向展收机构,由径向展收机构与中心面板展收机构中两端的底座相连。左、右侧面板展收机构自由度为1,径向和轴向同步运动;完全展开时,左、右侧面板展收机构所形成的曲面可以为一指定的抛物面、圆柱面等柱面,完全收拢时各面板紧凑折叠,减少体积。且通过上述设计的展收机构为基本单元,进行轴向扩展,可拓展成为更大尺度的展收机构。
