Problems solved by technology

[0012] The use of this technology currently has the following defects: 1. It can only realize the developability of a plane or a simple curved surface, and cannot realize the developability of a general free-form surface; 2. The scope of application is not wide enough, and it is currently used in social life less

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] The fully folded structure for realizing free-form surfaces provided by the present invention includes several bidirectionally orthogonal scissor-hinge bar units, nodes and fixing devices; the scissor-hinge bar units are connected to each other through nodes to form a whole; the The structure has one degree of freedom of movement; after the structure is completely folded into a bundle of rods, it is unfolded to form a free-form grid surface by controlling the angle between the scissor-hinge rod units; the fixing device is used to solidify the free-form grid surface, Makes a free mesh surface stable without degrees of freedom of motion.

[0043] Each scissor-hinge bar unit includes four plane scissor-hinge units, namely the first plane scissor-hinge unit A, the second plane scissor-hinge unit B, the third plane scissor-hinge unit C and the fourth plane hinge uni...

Abstract

The invention relates to a full-folding structure for implementing free-form surfaces and a method thereof. The full-folding structure comprises a plurality of two-way orthogonal scissors-type rod units, joints, and fixing devices; the scissors-type rod units are connected into a whole through the joints; the full-folding structure has one degree of freedom; after fully folded, the structure forms a rod bundle, and the structure can be unfolded into a free-form grid surface by controlling the angles of the scissors-type rod units; the fixing devices are used for fixing the free-form grid surface so that the free-form grid surface loses the degree of freedom of motion and keeps stable. The full-folding structure is novel in form, reasonable in structural stress, convenient for drive control and quick to assemble and construct, and has good application prospect.

Description

technical field [0001] The invention relates to an expandable structural system, in particular to a fully foldable structural system capable of realizing free-form surfaces. Background technique [0002] Existing technologies are mainly composed of bar system unit structures to form deployable structures or components. [0003] The bar system unit structure mainly includes: [0004] (1) A double-layer expandable grid structure is formed by a scissor hinge structure [0005] The scissor unit is composed of two or more rods whose middle parts are hinged to each other and can rotate each other. Several units are connected to each other through the hinge points at the ends to form a basic piece unit, and then form a deployable structure through hinges. [0006] The double-layer deployable grid structure based on scissor elements can be divided into a self-stabilized deployable structure and an additional support-stabilized structure. The former does not need additional support...
