Wing device of flapping machine

The invention belongs to the technical field of flatting machine preparing, and particularly relates to a wing device of a flapping machine. A main structure comprises a connecting shaft, a left support, a right support, main frameworks, ribs, films, a left wing and a right wing. The left support and the right support are fixedly arranged on the connecting shaft. The connecting shaft is fixedly connected with a power machine of the flapping machine through the left support and the right support. The left support and the right support support the rotation of the connecting shaft. Each of the left wing and the right wing is formed by connecting and combining the main frameworks, the ribs and the films in a matched manner. The main framework of the left wing and the main framework of the right wing are in mechanical transmission connection with the connecting shaft. The components are matched to form a wing structure of the flapping machine. Climbing force and advancing force are provided for flight through power generated by left-and-right swinging when a fish tail moves, and a flight mechanism of the flight state of the flapping machine is achieved. The wing device is simple in structure, scientific in principle, low in manufacturing cost, easy to regulate, good in flight effect and wide in application prospect.
