The invention discloses a single-degree-of-freedom planar two-dimensional deployable basic unit and a large-scale deployable device. The expandable basic unit is a symmetrical quadrangular prism multi-closed-loop mechanism and comprises two platforms which are arranged in parallel, and a driving branch chain is connected between the two platforms; the end faces where the two platforms are located are each provided with a plane connecting rod mechanism, and the four opposite side faces of the two platforms are each provided with a connecting mechanism. The driving branch chains are positioned on the central axes of the expandable basic units, and are provided with cylindrical pairs; the plane connecting rod mechanism is provided with four same plane connecting rods, one ends of the plane connecting rods are hinged to the platform, and the four plane connecting rods are all located in the plane where the platform is located; the connecting mechanism is connected with the two adjacent plane connecting rods in the two plane connecting mechanisms. The single-degree-of-freedom parallel mechanism has the advantages of good symmetry, high rigidity, light weight, high structural reliability, single degree of freedom and simple driving system.

    本发明公开了一种单自由度平面二维可展开基本单元及大尺度可展开装置。可展开基本单元为对称的四棱柱多闭环机构,其包括平行设置的两个平台,两个平台之间连接有驱动支链;在两个平台所在端面分别设有一组平面连杆机构,在两个平台的四个相对侧面分别设有一组连接机构;驱动支链位于可展开基本单元的中心轴线上,驱动支链具有圆柱副;平面连杆机构具有四个相同的平面连杆,平面连杆的一端与平台相铰接,且四个平面连杆均位于平台所在平面内;连接机构分别与两个平面连接机构中相邻的两个平面连杆相连接。本发明具有良好的对称性,同时具有高刚度、轻量化、结构可靠性高、单自由度和驱动系统简单诸多优点。
