Problems solved by technology

[0004] Existing spatially expandable structures mainly involve folding on planes or curved surfaces, such as solar panels and satellite antennas, while folding mechanisms involving volume are mainly obtained by non-rigid deformation. The deformation process is not conducive to control and is not easy to repeat. , the existing body-like expandable structures that adopt rigid deformation are either complex in structure, such as the foldable expandable polyhedron structure driven by a regular polygon mechanism proposed by C.M.Gosselin and D.Gagnon-Lachance in 2006; or cannot be completely folded, such as Kiper and The foldable polyhedron structure proposed in 2009
Therefore, body-shaped expandable structures are still relatively seldom used at present, and there are deficiencies such as incomplete folding and small folding and unfolding ratios.

Abstract

The invention discloses a single-degree-of-freedom foldable box structure, which includes ten faces, which are the first face, the second face, the third face, the fourth face, the fifth face, the sixth face, the seventh face, The eighth, ninth, and tenth faces; the first and second faces are connected as the bottom of the foldable box structure and placed in the middle, and the third, fourth, fifth, and fourth faces The six sides, the seventh side, the eighth side, the ninth side, and the tenth side are placed above the first side and the second side and are connected end to end in sequence and form the bottom surface with the first side and the second side. The sides are connected; the structure is a combination of over-constrained mechanisms, which has good rigidity, and can be completely folded and unfolded. When folded, the volume is small and convenient for transportation. One degree of freedom, simple motion control; it has the advantages of simple production and processing, convenient motion control, and high reliability.

Description

technical field [0001] The invention relates to a foldable box structure, in particular to a single-degree-of-freedom, large fold-to-expand ratio foldable box structure based on an origami structure. Background technique [0002] Due to its good symmetry, polyhedral structures are widely used in aerospace, architectural structures, artworks and daily life. However, due to their large size and unfavorable transportation, polyhedral structures are often only used in fixed occasions. Cube small satellites, which were rated as one of the top ten scientific and technological breakthroughs in 2014 by the SCIENCE journal, are typical representatives of the aerospace field in pursuit of miniaturization and low-cost launch. However, the shortcoming of its small working space in the orbital state also restricts its further application. [0003] The space body-shaped foldable structure is a new type of structure born with the development of aerospace technology. It is in a folded stora...
