The development history of Chinese space mechanism technology was summarized in this paper. Three research hotspots such as lightweight-large deployment mechanism,high pointing accuracy position mechanism and smart operating mechanism were introduced,considering the application requirements of China space technology. According to the complexity of space mechanism and its role in spacecraft systems,the development trends of space mechanism from single devices to subsystems to mechanical systems(platform) were summarized. In the end,the technical characteristics of space mechanism development: structure-mechanism integrated simulation,material-mechanism integrated design,control-mechanism integrated design were suggested. The necessity and importance in strengthen the research on flexible structure dynamics analysis,large deformation material manufacture and forming,microdriving technique were put forward.
