Wings and a transmission mechanism of an ornithopter. The wings are divided into inner wing panels, middle wing panels and outer wing panels. The transmission mechanism drives a crankshaft by means of a motor. The crankshaft drives a connecting rod. One end of a stator passes through a gap at the middle of the connecting rod, and the other end of the stator is fixed to a body. The front end of the connecting rod is connected to certain ends of inner sides of rear skeletons of the inner wing panels separately. The rear skeletons of the inner wing panels pass through the body outwards. The body serves as a pivot. The certain ends of outer sides of the rear skeletons of the inner wing panels are connected to lower end vertexes of inner sides of rectangular skeletons, which can be changed into rhombuses, of the middle wing panels. Certain ends of front skeletons of the inner wing panels are fixed to the body, and the other ends of the front skeletons of the inner wing panels are connected to upper end vertexes of the inner sides of the rectangular skeletons, which can be changed into rhombuses, of the middle wing panels. Under the combined action of the front skeletons and rear skeletons of the inner wing panels, forms can be changed continuously. Shape-preserving wings of the outer wing panels are connected to the outer sides of the middle wing panels by means of hinges, and angle limitation devices on the hinges of the outer wing panel are configured to limit oversize lifting angles of the outer wing panels. In such a way, the movement of an ornithopter can present the states of birds in a flying process. |
