AI Technical Summary

Problems solved by technology

The geometric overconstraint of the mechanism makes it highly rigid, but it also has high requirements for the precision and assembly of the hinge. The error of the hinge will lead to problems such as inaccurate control of motion and large frictional resistance.
Especially for thick plate origami structures, the traditional rotating pair assembly is difficult

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention will be further described:

[0027] Such as Picture 1-1 with Figure 1-2 A foldable slab structure using rolling hinges is shown, including six slab units, respectively the first slab unit 1, the first slab unit 2, the third slab unit 3, and the fourth slab unit 4. The fifth thick plate unit 5 and the sixth thick plate unit 6. The six thick plate units are connected to each other by rolling hinges, namely the first rolling hinge R1, the second rolling hinge R2, the third rolling hinge R3, the fourth rolling hinge R4, the fifth rolling hinge R5, the sixth rolling hinge R6, the Seven rolling hinges R7.

[0028] The rolling hinge includes a connecting structure arranged on the thick plate unit, combined with Figure 2-1 to Figure 2-6 As shown, the first thick plate unit 1, the third thick plate unit 3, the fourth thick plate unit 4, and the sixth thick plate unit 6 are all provided with two connectin...

Abstract

The invention discloses a foldaway thick plate structure adopting rolling hinges. The foldaway thick plate structure adopting the rolling hinges has three symmetrical planes, namely a first symmetrical plane, a second symmetrical plane and a third symmetrical plane respectively, which are perpendicular to one another, and comprises six thick plate units which are connected with one another through the rolling hinges; each rolling hinge comprises a connecting structure arranged on the corresponding thick plate unit; each connecting structure is formed by a rounded corner which is integrally formed with the corresponding thick plate unit; a through hole and a groove which are used for connecting each connecting structure through a flexible wire are formed in the corresponding rounded corner. The invention aims to overcome the disadvantages in the prior art, and provides the foldaway thick plate structure adopting the rolling hinges. The structure has a single freedom degree, and can control the folding and unfolding processes of the structure precisely at the single freedom degree; the structure is large in flex-grow, simple in structure, and easy to install; the folding friction force and unfolding friction force are low.

Description

technical field [0001] The present invention relates to a foldable structure, and more particularly to a foldable slab structure using rolling hinges. Background technique [0002] Origami is an art with a long history, and its essence is to fold two-dimensional flat materials into three-dimensional structures. In recent years, according to the characteristics of origami folding and fast and low-cost manufacturing, a variety of foldable and unfoldable engineering structures have emerged, such as solar panels, openable roof structures, and robots. In these applications, the plate of the origami model is simplified as a rigid body with zero thickness, and the creases of the origami model are simplified as hinges for motion analysis. However, in practical applications, the thickness of the plate cannot be ignored. There are large errors in the analysis results and the problem of physical interference. Professor Chen Yan put forward the theory that the thick plate origami mode...
