Abstract

The invention discloses a single-degree-of-freedom symmetric space seven-rod closed-loop mechanism and a space expanding mechanism based on same. A frame is hinged to a support rod through a frame branched rod; one end of the support rod is hinged to the frame branched rod, and the other end is hinged to a first connecting rod, and meanwhile, is hinged to a second connecting rod; one end of the first connecting rod is hinged to the support rod, and the other end is hinged to a first connection rod; one end of the first connection rod is hinged to the first connecting rod, and the other end ishinged to a second connection rod; one end of the second connection rod is hinged to the first connection rod, and the other end is hinged to the second connecting rod; and one end of the second connecting rod is hinged to the support rod, and the other end is hinged to the second connection rod. The support rod can be driven to fold and unfold the space expanding mechanism to form an umbrella shape and a plane; and the mechanism is conveniently controlled in the folding and unfolding process.

Description

technical field [0001] The invention belongs to the technical field of mechanism application, and in particular relates to a single-degree-of-freedom symmetrical space seven-bar closed-loop mechanism and a space expandable mechanism based thereon. Background technique [0002] Space expandable mechanisms have a very wide range of applications in the fields of opening and closing roofs, large space expandable antennas, space expandable support arms, and solar cell arrays. With the development of science and technology, more and more workplaces require institutions to have more work stages, and institutions should have corresponding functions in different work stages. For the umbrella-shaped space expandable mechanism, a single umbrella-shaped unfolding shape can no longer meet the multifunctional requirements of the umbrella-shaped expandable mechanism, which limits the development of the umbrella-shaped expandable mechanism and the umbrella-shaped expandable mechanism in mul...
