The invention discloses a miniaturized high-rigidity unfolding and locking mechanism for a moonlet solar wing, which is characterized in that a male hinge and a female hinge are mainly used for providing mounting interfaces for a solar wing substrate, and connecting rods, the male hinge and the female hinge form a four-connecting-rod mechanism through a main shaft and a supporting shaft; the main shaft spring is inserted on the main shaft, and the main shaft spring and the auxiliary spring jointly act to provide driving torque for unfolding and locking; the self-locking function of the four-connecting-rod mechanism after being unfolded in place and the manual folding function after being locked can be achieved; the polyimide shaft sleeve is selected for axial limiting and friction, the size is small, the weight is light, and the driving torque is large; fine adjustment of the unfolding angle in the assembling process can be achieved, and adjustment of the tightening value of the main driving torque in the assembling process can be met. The problems that an unfolding and locking mechanism of a moonlet solar wing is small in driving torque, complex in structure, large in assembly difficulty and the like are solved.
本发明公开了一种用于小卫星太阳翼的小型化高刚度展开锁定机构,公铰和母铰主要为太阳翼基板提供安装接口,各连杆通过主轴、支撑轴和公铰、母铰组成四连杆机构;主轴弹簧穿插在主轴上,与辅助弹簧共同作用为展开锁定提供驱动力矩;可实现展开到位后的四连杆机构自锁功能及锁定后的手动收拢功能;选用聚酰亚胺轴套进行轴向限位与摩擦,本发明体积小,重量轻,驱动力矩大;可实现装配过程中的展开角度微调,能满足装配时主驱动力矩上紧值的调整。解决了小卫星太阳翼的展开锁定机构驱动力矩小、结构复杂、装配难度大等问题。
