The invention relates to a light shield system capable of being automatically unfolded, and aims to solve the technical problem that an existing light shield only has a degree of freedom in one direction and still occupies a large space after being folded. The light shielding cover comprises a light shielding cover assembly and a light shielding cover fixing device, wherein the light shielding cover assembly comprises a light shielding cover film and N groups of extensible light shielding cover brackets; the N groups of light shield supports are arranged in the circumferential direction of the cubesat platform, each group of light shield supports comprises two extension supports, and each extension support comprises a radial supporting rod and an axial supporting rod; the radial supporting rods are telescopic rods, the fixed ends of the radial supporting rods are hinged to the bottom face in the cubesat platform, and the telescopic ends of the radial supporting rods are hinged to the axial supporting rods. The axial supporting rod is a folding rod; the light shield film is of a flexible cylindrical structure and is arranged on the axial supporting rods of the N sets of light shield supports in a sleeving mode. The light shield bracket is contracted in the cubesat platform and forms a light shield space surrounding the cubesat platform after being unfolded; the light shield assembly fixing device is used for fixing the light shield support in the contraction state.
本发明涉及一种可自动展开的遮光罩系统,目的是解决现有遮光罩只有一个方向的自由度,折叠后依旧占据很大空间的技术问题。其包括遮光罩组件和遮光罩固定装置,遮光罩组件包括遮光罩薄膜和N组可延展式遮光罩支架;N组所述遮光罩支架沿立方星平台周向布置,每组遮光罩支架包括两个延展支架,每个延展支架包括径向支撑杆和轴向支撑杆;径向支撑杆为伸缩杆,径向支撑杆的固定端铰接立方星平台内部的底面,伸缩端与轴向支撑杆铰接;轴向支撑杆为折叠杆;遮光罩薄膜为柔性筒状结构,套装在N组遮光罩支架的轴向支撑杆上;遮光罩支架收缩在立方星平台内部,展开后形成一个围绕立方星平台的遮光空间;遮光罩组件固定装置用于固定收缩状态的遮光罩支架。
