The invention discloses a moonlet solar wing unfolding and locking mechanism. The moonlet solar wing unfolding and locking mechanism comprises a male hinge piece, a female hinge piece, a rotating shaft for connecting the male hinge piece and the female hinge piece, a microswitch installed on the female hinge piece, a power wheel installed on the male hinge piece, a constant-torque spring installed on the power wheel, a supporting shaft for preventing the constant-torque spring from being folded, a leaf spring hook playing a locking role and the like. And the unfolding locking mechanism performs folding and unfolding actions around the rotating shaft. In the unfolding process, the male hinge piece and the female hinge piece are driven by the constant-torque spring to be unfolded around the rotating shaft, the two wedge-shaped bosses on the female hinge piece are hooked by the two leaf spring hooks when the maximum unfolding angle is achieved, and the locking action of the unfolding locking mechanism is completed. When the unfolding locking mechanism is folded, the leaf spring hook needs to be unlocked in advance, and then the unfolding locking mechanism is slowly folded. The invention has the advantages of compact structure, high reliability, light weight, small volume, low cost and the like.
本发明公开了一种小卫星太阳翼展开锁定机构,包括:公铰片、母铰片,连接公铰片与母铰片的回转轴,安装在母铰片上的微动开关,安装在公铰片上的动力轮,安装在动力轮上的恒力矩弹簧,防止恒力矩弹簧收拢的支撑轴,起锁定作用片簧钩等。该展开锁定机构绕着回转轴进行收拢和展开动作。在展开过程中,公铰片和母铰片在恒力矩弹簧的驱动下绕着回转轴进行展开,达到最大展开角度时两个片簧钩将母铰片上的两个楔形凸台钩住,并完成展开锁定机构的锁定动作。展开锁定机构收拢时,需提前解锁片簧钩,再缓慢收拢。本发明具有结构紧凑,可靠性高,重量轻,体积小,成本低等优点。
