Abstract: Based on the new technology,new material and new structure of the in-orbit deployable mechanism of large-scale spacecraft components involved in the development of spacecraft towards large scale and long distance,the deployable mechanism of large-scale components on the existing spacecraft was analyzed statistically,and the technical parameters,structures and compositions of foldable mechanisms of in-orbit spacecraft were systematically combed.The application of new craft and materials including origami art,self-rebound materials and shape memory alloys in large-scale components,such as solar sails and antennas of spacecraft,was introduced.The characteristics and working principle of new structures including inflatable type,axial rotating type,radial expansion type,reconfigurable type,linear elongation type,etc,were analyzed and combed.Finally,in conjunction with the upcoming moon landing,construction of a lunar base,exploration of solar system and other deep space exploration missions,the trend of development about the large-scale components of in-orbit spacecraft was prospected.

Key words: spacecraft, origami art, self-rebound, shape memory alloy, deployable mechanism
