The invention discloses an ornithopter capable of sweeping double crankshafts to control double-wing flapping, and belongs to the technical field of aircrafts, the ornithopter comprises a body frame, a double-crankshaft transmission flapping mechanism, a disc cam variable sweep angle mechanism, a left flapping wing, a right flapping wing and a tail vane, the double crankshafts of the double-crankshaft transmission flapping mechanism are driven by a driving motor to rotate; the double-crankshaft is in an S shape and comprises a front crankshaft section and a rear crankshaft section, the two sections are connected with the inner ends of a left bent rocker piece and a right bent rocker piece which are coupled to the left side and the right side of the machine body frame through a left connecting rod and a right connecting rod respectively, and the outer ends of the left bent rocker piece and the right bent rocker piece are connected with wing root connecting pieces and flapping wings in sequence; the disc cam variable sweep angle mechanism comprises a disc cam, a sliding piece, an elastic reset piece and a sweep connecting rod, the sliding piece can slide front and back and makes contact with the outer contour of the disc cam through the elastic reset piece, and the disc cam rotates to drive the sliding piece to slide front and back in a reciprocating mode. And the sweeping connecting rods on the two sides drive the wing root connecting pieces and the flapping wings to perform front-and-back sweeping flapping motion.

    本发明公开了一种可扫掠双曲轴控制双翼扑动的扑翼飞行器,属于飞行器技术领域,它包括:机体框架、双曲轴传动扑动机构、盘形凸轮变掠角机构、左右扑翼、尾舵,所述双曲轴传动扑动机构由驱动电机驱动双曲轴转动;所述双曲轴呈“正S形”包括前曲轴段和后曲轴段,二段分别通过左连杆和右连杆与轴接于机体框架左、右两侧的左弯摇杆件、右弯摇杆件内端连接,其外端均依次连接翼根连接件和扑翼;所述盘形凸轮变掠角机构包括盘形凸轮、滑动件、弹性复位件、扫掠连杆,所述滑动件可前后滑动,通过弹性复位件使其与盘形凸轮的外轮廓接触,盘形凸轮转动带动滑动件前后往复滑动,进而通过其两侧扫掠连杆带动翼根连接件及扑翼进行前后扫掠的扑动运动。
