The invention discloses a rotating shaft assembly of a folding empennage comprising multiple locking mechanisms, and relates to the technical field of unmanned aerial vehicles. Comprising a machine body connecting piece, an axial locking end cover, a driving rotating shaft, a wing connecting piece, a locking sleeve and a driven rotating shaft, the wing connecting piece and the driving rotating shaft rotate synchronously, the driven rotating shaft and the wing connecting piece rotate synchronously and can slide in the wing connecting piece, and the locking sleeve is fixedly connected with the machine body connecting piece and can be clamped with the driven rotating shaft in an automatic sliding manner; a driving torsion spring between the driving rotating shaft and the machine body connecting piece drives the wing connecting piece to rotate; the axial locking end cover completes primary locking on the driving rotating shaft through the first conical pin, the driving rotating shaft completes secondary locking with the machine body connecting piece through the two-way elastic pin, and the driven rotating shaft and the machine body connecting piece complete tertiary locking through the fan-shaped boss. The wing locking device is simple in structure, the locking stability after the wing is unfolded in place is improved through three times of locking, and the locking reliability index meets the requirement.
本发明公开了一种包含多锁止机构的折叠尾翼的旋转轴组件,涉及无人机技术领域。包括机体连接件、轴向锁止端盖、主动旋转轴、机翼连接件、锁止套筒、被动旋转轴;机翼连接件与主动旋转轴做同步转动,被动旋转轴与机翼连接件同步转动并可在机翼连接件内滑动移动,锁止套筒固定连接机体连接件并可与被动旋转轴自动滑动卡接;主动旋转轴与机体连接件之间的驱动扭簧驱动机翼连接件旋转;轴向锁止端盖通过第一圆锥形销对主动旋转轴完成一次锁止,主动旋转轴通过双向弹性销与机体连接件完成二次锁止,被动旋转轴与机体连接件之间通过扇形凸台完成三次锁止。本发明结构简单,通过三次锁定提高机翼展开到位后锁定的稳定性,使锁紧可靠性指标达到要求。
