Abstract

The invention discloses a regular hexahedral symmetrical deployable mechanism unit which is composed of 32 three-rod intersected connecting nodes and 48 connecting rod units, and comprises two completely same and symmetrically-arranged spatial structures, wherein the two spatial structures are connected by using a connecting rod unit 2, and each connecting node is respectively connected with three connecting rod units by using a revolute pair. Each three-rod intersected connecting node comprises 8 first-type nodes and 24 second-type nodes, the axes of three revolute pairs of the first-type nodes constitute an equilateral triangle, and the axes of three revolute pairs of the second-type nodes constitute an isosceles right triangle. The deployable mechanism unit disclosed by the invention is just composed of connecting rods and revolute pairs, so that the deployable mechanism unit is simple in structure manufacturing and beautiful in geometric modelling, and can be folded and unfolded conveniently and repeatedly.

Description

technical field [0001] The invention relates to a mechanism and an expandable structure, in particular to a regular hexahedron symmetrical expandable mechanism unit. Background technique [0002] In the 1960s, the Spanish architect Pinero successfully introduced the idea of ​​structural unfolding-folding into the design of the folding roof (US Patent No. 3185164). Subsequently, with the rapid development of large-span space structures and aerospace technology, the research on deployable structures has become a hot topic in the fields of building structures, aerospace, military engineering, etc., and deployable structures based on scissor-hinge units are widely used. , has attracted the attention of researchers at home and abroad. The existing literature and related invention patents have studied the geometric configuration, deployability, and mechanical properties of some deployable structures composed of scissor-hinge units from the perspective of mechanism. Zeiger propos...
