Problems solved by technology

[0003] Polyhedral structures are widely used because of their good symmetry, but the existing polyhedral structures are either bulky when empty, which is not conducive to transportation, such as containers, etc.; or the folding process is complex, with many degrees of freedom, and difficult to control, such as foldable Tent etc.
These characteristics greatly limit the application of polyhedral structures.

Embodiment Construction

[0043]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0044] Such as Figure 1-21 As shown, an expandable foldable single-degree-of-freedom polygonal prism includes a bottom unit and a node unit. The two base units are directly connected to form a basic prism, and the two bottom units are connected to form by at least one sequentially connected node unit. extended prism;

[0045] The bottom unit includes a bottom module and a side module, and the node unit includes two side modules;

[0046] The bottom module includes two symmetrical triangular plates A and two symmetrical triangular plates B, and the side module includes two symmetrical rectangular plates A and two symmetrical rectangular plates B;

[0047] The middle part of one side of the triangular plate A is provided with a boss with the same thickness as the plate. The th...

Abstract

The invention relates to an expandable foldable single-degree-of-freedom polygonal prism which comprises bottom units and joint units, the two bottom units are directly connected to form a basic prism, and the two bottom units are connected through at least one joint unit which is connected in sequence to form an expansion prism; the bottom unit comprises a bottom module and a side module, and the section unit comprises two side modules; the bottom module comprises two triangular plates A which are symmetrically arranged and two triangular plates B which are symmetrically arranged, and the side module comprises two rectangular plates A which are symmetrically arranged and two rectangular plates B which are symmetrically arranged. The design has the advantages of single degree of freedom, large deployable ratio, foldability, infinite expansion, complete closing and self-locking after unfolding, good stability and convenience in transportation and storage.

Description

technical field [0001] The invention relates to an expandable foldable single-degree-of-freedom polygonal prism. Background technique [0002] The expandable structure can adapt to a variety of working conditions by changing its own shape. It has the advantages of large folding and expansion ratio, convenient transportation and storage, etc. It not only has broad application prospects in aerospace, civil engineering, military engineering and other fields, but also has broad application prospects in life and rescue. Has many applications. [0003] Polyhedral structures are widely used because of their good symmetry, but the existing polyhedral structures are either bulky when empty, which is not conducive to transportation, such as containers, etc.; or the folding process is complex, with many degrees of freedom, and difficult to control, such as foldable tent etc. These characteristics greatly limit the application of polyhedral structures.
