A composite structure of deployable multi-cubes

Abstract

The invention provides an unfoldable multi-cube composite structure. The composite structure comprises a plurality of unfoldable cubes and a plurality of connection pieces, and the unfoldable cubes comprise a plurality of variable unfolded surfaces; the multiple unfoldable cubes are combined and spliced in a face-to-face manner correspondingly and combined into the composite structure of the unfoldable multi-cube through connection of the connection pieces; the connection pieces are T-shaped connection pieces, or L-shaped connection pieces or connection pieces shaped like the Chinese character 'yi'; pairs of the variable unfolded surfaces, located on the same plane, of every two adjacent combined unfoldable cubes are combined in a hinged manner through the T-shaped connection pieces or / and the connection pieces shaped like the Chinese character 'yi'. The composite structure of the unfoldable multi-cube is simple in structure, fabrication materials are greatly saved, mechanism stretching and contracting resistance is small, the cost is low, installation manpower is saved, and production efficiency is high; and a stretching and contracting structure is obvious in change, the application range is broadened, the composite structure can be applied to fields of toys, buildings, bridges, spaceflight and the like, and the composite structure can be configured to large unfoldable characters of light and applied to multi-shaped storage structures.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a composite structure of a developable multi-cube. Background technique [0002] At present, the retractable and foldable structure has a wide range of applications and development. It has a large expansion ratio and can effectively reduce the occupied space when shrinking. It is often used in many industries, such as machinery and equipment, engineering construction, exhibition booth construction, as well as teaching aids and application in toys. [0003] However, the current retractable and foldable structure is often limited by its limited degree of expansion and contraction, and is often limited by isolation and singleness. In the application of high-stress structural engineering, its stability has certain defects, and the overall shape is beautiful. The degree of and abundance is single, and there is a problem of high manufacturing cost and waste of resources. Therefore, ...

Problems solved by technology

[0003] However, due to the limited degree of expansion and contraction of the current stretchable folding structure, it is often isolated and single. In the application of high-stress structural engineering, its stability has certain defects, and the aesthetics of the overall shape and the degree of richness is single, and there is a problem of high manufacturing cost, resulting in waste of resources. Therefore, further technical development is required to increase the functions and effects of the retractable folding structure, expand its application range, and achieve decorative functions. Further technical improvements should be made to add functions such as three-dimensional storage, and the production process is simpler and lower-cost devices
