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.

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] Such as Figure 1a and Figure 1bAs shown, this embodiment provides a symmetrical foldable thick plate structure, including 17 plates with different shapes connected in sequence, plate 1 is a rectangular plate, placed in the middle, and the rest are plates 2 to 17, placed on the plate 1 around, and connected end to end in sequence, plate 2, plate 6, plate 10 and plate 14 are respectively connected to the four sides of plate 1, and the thick plate structure is a structure formed by connecting each other through rotating pairs. After the thick plate structure is completely folded, it becomes an approximately rectangular box without a cover. Plate 1 is the bottom plate of the box. Composition of rotating pair structure. Two plates and one revolving pair are shared between two spherical four-revolving pair structures in the same structure. Two plates and one rota...

The invention discloses a symmetrical foldable thick plate structure, which can form a box without a cover after being folded. The connection, as a whole, satisfies the condition of no interference between the plates during the folding process, and the symmetrical foldable thick plate structure can be combined side by side to form a foldable structure with a larger unfolded area. 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 symmetrical foldable thick plate 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, rigid origami often cannot be folded due to thickness problems in practical engineering applications. To solve this problem, Tachi (2011) and Hoberman (2010) proposed to move the axis of rotation to the edge of the ...
