The folding and locking integrated aviation actuator comprises a planetary gear mechanism and shells on the two sides, motors arranged in the shells drive gear rings and planet carrier shafts to rotate, the gear rings drive paddles to rotate to achieve folding and unfolding, and the planet carrier shafts drive lock pin frames to slide through transmission assemblies. The gear ring and the lock pin frame are locked through the first locking piece and the second locking piece correspondingly, so that folding and unfolding of the paddles are limited and locked. Due to the fact that when the actuator finishes folding and unfolding, the actuator can be locked, the situation that the gear ring is reversely driven by external force loads and a transmission system and a motor are damaged is avoided, the actuator adopts a single motor, folding and unfolding and locking and unlocking can be achieved through a mechanical time sequence, and the actuator has the advantages of being small in size, light in weight and easy to control.

    本发明公开了一种折叠锁定一体的航空作动器,包括行星齿轮机构以及两侧的壳体,通过壳体内设置的电机带动齿圈与行星架轴旋转,齿圈带动桨叶进行旋转实现折叠与展开,行星架轴通过传动组件带动锁销架进行滑动,通过第一锁定件与第二锁定件分别锁定齿圈与锁销架实现对桨叶折叠与展开的限制与锁定。由于在作动器完成折叠与展开结束时,能够对作动器进行锁定,避免外力载荷反向驱动齿圈,损坏传动系统及电机,作动器采用单电机,通过机械时序即可实现折叠与展开及锁定与解锁两套动作,作动器具备体积小、重量轻、控制简单的优点。
