Abstract

The invention relates to a three-structure-state transformation space deployable mechanism based on scissor units. The three-structure-state transformation space deployable mechanism based on scissorunits is formed by scissor units, hinges and chassises, wherein the scissor units can be converted into a first structure-state, a second structure-state or a third structure-state through unfolding or furling; the first structure-state is a triangular prism structure-state; the second structure-state is a quadrangular structure-state; the third structure-state is a pentagonal prism structure-state; the hinges include a double-revolute-pair hinge and a three-revolute-pair hinge; and one end of the double-revolute-pair hinge is connected with the chassises through pins, and the other end of thedouble-revolute-pair hinge is connected to the scissor units through pins. The three-structure-state transformation space deployable mechanism based on scissor units has the advantages of being lightin weight, being single in the component type, being large in the folding ratio, being small in the furled volume, being stable in mechanism deploying, and having variable three structure states, being able to be used as a polygonal space folding unit, and being suitable for an aerospace support frame and a planar transmitting antenna.

Description

technical field [0001] The invention relates to the field of space unfolding mechanisms, in particular to a space expandable mechanism based on three-configuration transformation of a scissors unit. Background technique [0002] With the vigorous development of the aerospace industry, the exploration of outer space has gradually deepened. Some large-scale spacecraft supports such as radar antenna supports and large-diameter space antenna supports require different types of supports to meet different aerospace needs; At present, many space unfolding mechanisms and supporting frames of spacecraft can form a space unfolding mechanism with stable deployment and large folding ratio through the array or topology of the unfolding units. [0003] Chinese patent 201210464544.1 discloses a triangular prism foldable unit and a foldable support arm composed of the foldable unit. The mechanism has a triangular prism foldable unit configuration; Chinese patent 201010176640.X discloses a ...
