The invention relates to a single-degree-of-freedom infinitely expandable and deployable structure with quadrilateral components, which comprises a plurality of identical quadrangles with four connecting vertexes, wherein the quadrangles with the four connecting vertexes are sequentially and movably connected with other four adjacent quadrangles with the four connecting vertexes through revolute pairs. The quadrilateral unfolding device is simple in structure, the vertex of each quadrilateral is provided with one revolute pair, a plurality of quadrilateral units can be connected according to actual requirements of users, and the quadrilateral unfolding device has infinite unfolding performance and is suitable for unfolding large-scale space. The whole mechanism is in single-degree-of-freedom motion, and one axial cylindrical surface can be converted into the other axial cylindrical surface perpendicular to the axial cylindrical surface; the mechanism has the advantages of being good incontrollability, large in folding ratio and good in repeatable folding and unfolding performance.
Description
technical field [0001] The invention relates to an infinitely expandable and deployable structure, especially a single-degree-of-freedom infinitely expandable and deployable structure with a quadrilateral member and its application. Background technique [0002] The deployable structure is a new type of structure that has been rapidly developed over the past half century with the increasing area of solar arrays required on spacecraft and the support requirements of satellite antennas. The deployable structure is folded into a specific shape during transportation and storage, and when it needs to work, under the action of external force, the structure gradually unfolds to reach the working state. Deployable mechanisms are widely used in solar cell arrays, satellite antenna support frames and other fields. [0003] Common deployable structures are mainly divided into non-rigid deployable structures and rigid deployable structures. Inflatable non-rigid deployable structures...
