A foldable thick plate box structure

Abstract

The invention discloses a foldable thick plate box structure, which can form a box without a cover after being folded, and two diagonal structures of the four bottom corners of the box are respectively composed of two spherical four-rotation pair structures, and the other The two diagonal structures are respectively composed of a spherical four-rotation pair structure and a spherical five-rotation pair structure. The plates are connected through the rotating pairs, and the whole meets the condition of no interference between the plates during the folding process. The present invention can realize two states of folding and unfolding. When folded, the volume is smaller for storage or transportation, and when unfolded, it has a larger working space; the whole frame has one degree of freedom, and has the advantages of simple production and processing, convenient motion control, high reliability, etc. Advantages, it has broad application prospects in aerospace, construction and other fields.

Description

technical field [0001] The invention relates to a foldable thick plate structure, in particular to a foldable thick plate box structure based on an origami structure with a single degree of freedom and a large fold-to-expand ratio. Background technique [0002] Origami is the art of folding two-dimensional materials such as paper into three-dimensional objects. In recent years, the technique has gained a lot of attention in both the scientific and engineering communities for its ability to create deformable structures. A branch of origami, rigid origami, which uses hinges to connect rigid objects into movable mechanisms, has promising applications in engineering structures -- from solar panels, space mirrors and aircraft wings to robots. As we all know, in practical engineering applications, rigid origami often cannot be folded due to thickness problems. To solve this problem, Tachi (2011) and Hoberman (2010) proposed to move the axis of rotation to the edge of the panel, ...

AI Technical Summary

Problems solved by technology

[0003] Existing spatially expandable structures mainly include hinge expandable structures, rod-like expandable structures, surface-like expandable structures, and body-like deployable structures. At present, there are still relatively few applications, and there are shortcomings such as incomplete folding and small folding and unfolding ratios. Planar expandable structures are used in solar sails, building roofs, etc.
