The bionic bat flapping wing aircraft comprises a fuselage frame, the fuselage frame is provided with a power assembly, a wing assembly and a leg assembly, and wing membranes cover the wing assembly and the leg assembly; the power assembly comprises a power source and a transmission mechanism which are in transmission connection, the transmission mechanism comprises at least two stages of speed reducing mechanisms, and output shafts of the speed reducing mechanisms are connected with the wing assemblies; the wing assembly comprises a wing framework, a flapping mechanism and a folding mechanism, wherein the flapping mechanism and the folding mechanism drive the wing framework to act. The flapping mechanism comprises a crank, a middle connecting rod and a rocker which are sequentially spherically hinged, the crank is connected with the output end of the speed reducing mechanism, and the rocker is connected with the wing framework. After being input by a single motor, the wings are simultaneously output to crank rocker mechanisms on the two sides, so that the wings on the two sides flap at the same time without errors; a leg angle adjusting mechanism is provided to adjust the local attack angle of the airfoil so as to realize the high-maneuverability dive flight attitude. Therefore, the problems of the existing bionic bat flapping wing aircraft are solved.
本发明公开了一种仿生蝙蝠扑翼飞行器,包括机身框架,机身框架设置有动力组件、翅翼组件和腿部组件,翅翼组件和腿部组件上覆设有翼膜;动力组件包括传动连接的动力源和传动机构,传动机构包括至少设置两级的减速机构,减速机构的输出轴连接翅翼组件;翅翼组件包括翅翼骨架,以及带动翅翼骨架动作的扑动机构和折叠机构;扑动机构包括依次球面铰接的曲柄、中间连杆和摇杆,曲柄连接减速机构的输出端,摇杆连接翅翼骨架。本发明用单电机输入后同时输出至两侧曲柄摇杆机构,实现两侧翅翼无误差同时扇动;提出一种腿部角度调节机构实现调整翼面局部攻角,以实现高机动性俯冲飞行姿态。从而解决现有仿生蝙蝠扑翼飞行器存在的问题。
