Claim 0:
1. An air vehicle with a double-layer rotor wing structure, comprising a cabin (1), a power device arranged in the cabin (1), and wherein the power device further comprising a drive assembly, a crankwheel (18), and a connecting link (19); wherein the connecting link (19) is fixed on the crankwheel (18); wherein the drive assembly drives the crankwheel (18) to rotate; wherein top of the cabin (1) is provided with a flying device further comprising a first flying unit and a second flying unit; wherein the first flying unit further comprising a sleeve (11), a first rotating bearing (10), and lower-layer rotor wings (7) symmetrically fixed on two sides of the first rotating bearing (10); wherein the first rotating bearing (10) is fixed to the sleeve (11) which is fixed to the cabin (1); wherein the second flying unit further comprising a transmission rod (9), a second rotating bearing (8), and upper-layer rotor wings (6) symmetrically fixed on two sides of the second rotating bearing (8); wherein the second rotating bearing (8) is fixed at the upper end of the transmission rod (9); wherein the lower end of the transmission rod (9) passes through the sleeve (11) and is hinged to the connecting link (19); wherein the transmission rod (9) and the sleeve (11) are connected through a linear bearing (24); wherein the drive assembly drives the transmission rod (9) to vertically move up and down in the sleeve (11) so that a relative opening and closing motion is generated between the upper-layer rotor wings (6) and the lower-layer rotor wings (7); and wherein the tail of the cabin (1) is provided with a propulsion device used for controlling the air vehicle to fly forwards.
