The invention discloses a large-scale space folding and unfolding unit and structure based on the paper folding principle, the large-scale space folding and unfolding unit comprises four long plates and four short plates, every two long plates and every two short plates form a group to form a folding and unfolding unit, in the first folding and unfolding unit, one end of the first short plate is hinged to the middle of the first long plate, and the other end of the first short plate is hinged to the middle of the second long plate; one end of the second short plate is hinged to the lower portion of the side face of the second long plate, one end of the second short plate is hinged to the middle of the second long plate and hinged to the upper portion of the side face of the first long plate, meanwhile, the connecting line of the four hinged shafts can be located at one point, namely, the folding and unfolding center point, and the second folding and unfolding unit is the same as the first folding and unfolding unit in structure and adopts the folding and unfolding center point as the axis. Part of the plate body of the first folding and unfolding unit is rotatably connected with part of the plate body of the second folding and unfolding unit, so that the two folding and unfolding units are connected together. The invention has the technical advantages of light weight, stable structure, reliable control system, realization of folding and unfolding of the paper folding structure and realization of large-scale driving.

    本发明公开了一种基于折纸原理的大尺度空间折展单元及结构,大尺度空间折展单元,包括四个长板和四个短板,其中每两个长板和两个短板为一组组成折展元,第一折展元中,第一短板的一端与第一长板中部铰接,与第二长板侧面的下部铰接,第二短板的一端与第二长板的中部铰接,与第一长板侧面的上部铰接,同时,四个铰接轴的连线能会于一点,即折展中心点,第二折展元与第一折展元结构相同,且与第一折展元以折展中心点为轴,水平方向上翻转对称,第一折展元的部分板体与第二折展元的部分板体可旋转连接,使两个折展元连在一起。本发明具有质量轻、结构稳定、控制系统可靠,能实现折纸结构折展、实现大尺度驱动的技术优点。
