The invention discloses a flapping wing mechanism with a variable rotor wing attack angle. The flapping wing mechanism comprises a motor, a driving assembly, a connecting assembly and a rotor wing mechanism, the output shaft of the motor is connected with the driving assembly; the driving assembly comprises a driving disc, a first connecting rod and a second connecting rod; the main shaft of the motor is fixedly connected with one surface of the driving disc; one end of the first connecting rod is fixed to the other side face of the driving disc, and the other end of the first connecting rod is hinged to one end of the second connecting rod. The connecting assembly comprises a third connecting rod and a fourth connecting rod; one end of the third connecting rod is fixedly connected with the fuselage, the other end of the third connecting rod is hinged to one end of the fourth connecting rod through a universal joint, and the other end of the second connecting rod is fixed to the fourthconnecting rod. The mounting shaft is perpendicular to the plane where the fourth connecting rod and the fuselage are located and fixed to the other end of the fourth connecting rod, and the rotors are rotationally connected with the mounting shaft; by adopting the mechanism, flapping wings of birds are simulated, lift force exists in the whole flapping process, and a rotor wing mechanism is combined on the basis of flapping, so that the flight efficiency is higher.

    本发明公开了一种旋翼迎角可变化的扑翼机构,包括:电机、驱动组件、连接组件和旋翼机构;电机输出轴连接驱动组件;驱动组件包括驱动盘、第一连杆和第二连杆;电机主轴与驱动盘一侧面固定连接,第一连杆一端固定在驱动盘的另一侧面,另一端与第二连杆的一端铰接;连接组件包括第三连杆和第四连杆;第三连杆一端与机身固定连接,另一端通过万向节与第四连杆一端铰接,第二连杆的另一端与第四连杆固定,旋翼机构包括安装轴和旋翼;安装轴与第四连杆和机身所在平面垂直,并固定在第四连杆的另一端,旋翼与安装轴转动连接;采用此方案模仿鸟儿扑动翅膀,且在扑动的整个过程中均存在升力,并在扑动的基础上结合了旋翼机构,使飞行效率更高。
