A large-space four-configuration transformable expandable mechanism, including a connecting rod, a telescopic scissor unit, a hinge and a chassis, one end of the connecting rod is connected to one end of the two-degree-of-freedom hinge through a pin, and the other end is connected to the Three-degree-of-freedom hinge connection, the telescopic scissors unit includes a telescopic connecting rod and a guide rod groove, one end of the telescopic connecting rod is connected to the three-degree-of-freedom hinge through a pin shaft, and the other end is connected to the guide rod groove through a moving pair. The hinges are divided into two-degree-of-freedom hinges and three-degree-of-freedom hinges, and the other end of the two-degree-of-freedom hinges is connected to the chassis through a pin shaft. The invention can transform from a planar configuration to a triangular prism, a quadrangular prism and a pentagonal prism, and has the characteristics of simple structure, stable unfolding, large folding ratio and variable four configurations, and can be flexibly applied to aerospace vehicle support frames.
Description
technical field [0001] The invention relates to the field of space expandable mechanisms, in particular to a large space expandable mechanism with four configuration transformations. Background technique [0002] With the vigorous development of the aerospace industry, the exploration of outer space is gradually deepening. It is necessary to transport some large spacecraft support frames such as radar antenna support frames and large-diameter space antenna support frames to outer space. Some in-orbit spacecraft are selected according to different tasks. Different spacecraft support frames meet the needs of spaceflight; at present, many space folding mechanisms and spacecraft support frames can form a space folding mechanism with stable deployment and large folding ratio through the array or topology of folding units. [0003] Chinese patent 201010176640.X discloses a space scissors telescopic mechanism, which has a single configuration of triangular units; Chinese patent 201...
