Foldable and unfoldable structure based on rectangular six-fold paper folding unit
The invention discloses a foldable and unfoldable structure based on a rectangular six-fold paper folding unit. The folding unit of the paper folding structure comprises six boundary points, an internal foldable and unfoldable point, six boundaries and six folds; the four boundary points are respectively positioned at four corners of a rectangular frame, and the other two boundary points are respectively positioned in two parallel sides of a rectangle; the six boundary points and the internal point are connected to form six creases, the four creases are mountain creases, and the two creases are valley creases. According to the invention, the advantages of large folding and unfolding ratio, graceful configuration and capability of realizing negative Poisson's ratio of a traditional Waterbomb folding paper are reserved. However, the axial symmetry of a traditional Waterbomb paper folding basic unit is reduced, so that the basic unit only needs to meet the rotational symmetry, and the complete rectangular six-fold paper folding structure can be formed by expanding the basic unit in parallel in the horizontal direction and expanding the basic unit in a staggered mode in the vertical direction. The constraint of the traditional Waterbomb folding paper is broken through, and the positive effect on increasing the shape diversity of the paper folding structure and promoting the application of the paper folding structure in engineering is achieved.
本发明公开了一种基于矩形六折痕折纸单元的可折展结构，该折纸结构的折叠单元包括六个边界点，一个内部可折展点，六条边界，六条折痕；四个边界点分别位于矩形框架的四个角处，另外两个边界点分别位于矩形两条相互平行的边内部；六个边界点与内部点的连接为六条折痕，其中四条为山折痕，两条为谷折痕。本发明保留了传统Waterbomb折纸折展比大，构型优美，能够实现负泊松比的优点。但降低了传统Waterbomb折纸基本单元的轴对称性，使得基本单元仅需满足旋转对称性，完整的矩形六折痕折纸构型可通过将基本单元水平方向上平行扩展、竖直方向上交错扩展而成。突破了传统Waterbomb折纸的约束，对增加折纸结构形状多样性以及推进折纸结构在工程中应用具有积极的作用。
