The invention discloses a seesaw type tilt rotor and an aircraft thereof, the seesaw type tilt rotor comprises a tilt mechanism mounted at the end of a wing, a driving motor and a plurality of steering engines, the driving motor and the steering engines are mounted on the tilt mechanism, the output end of the driving motor is coaxially connected with a main shaft, and an actuator cylinder is mounted on each steering engine; the main shaft is coaxially sleeved with a first action ring, wherein the first action ring and the tilting mechanism are arranged in a spaced mode. First hinge structures on the first action ring are hinged to the ends of piston rods of the corresponding action cylinders. The part, away from the tilting mechanism, of the first action ring is coaxially and rotationally sleeved with a second action ring, the second action ring and the main shaft are connected and rotate synchronously, a second hinge structure on the second action ring is connected with a variable-torque pull rod and a variable-torque rocker arm, and the other end of the variable-torque rocker arm is fixed to a paddle assembly so that total pitch change and periodic pitch change of paddles can be achieved. The inclination angles of the blades are automatically adjusted according to different flight states, higher stability and reliability are provided, and the damage degree of waving of the blades to the central part can be reduced.
本发明公开的一种跷跷板式倾转旋翼及其飞行器,包括安装在机翼端部的倾转机构、均安装在倾转机构上的驱动电机及多个舵机,驱动电机的输出端同轴连接有主轴,舵机上安装有作动筒;主轴上同轴套设有与倾转机构间隔设置的第一动作环,第一动作环上的各第一铰接结构与对应的各作动筒的活塞杆端部相铰接;第一动作环远离倾转机构的部分上同轴转动套接有第二动作环,第二动作环与主轴相连接并同步转动,第二动作环上的第二铰接结构连接变矩拉杆及变矩摇臂,变矩摇臂的另一端固定在桨叶组件上,以实现桨叶的总距变化和周期变距,根据不同的飞行状态自动调整桨叶的倾斜角度,提供更高的稳定性和可靠性,且能够减小桨叶挥舞对中央件的破坏程度。
