The invention discloses a bird-like aircraft flapping mechanism based on a double-crank rocker structure, and belongs to the technical field of bionic aircraft structure design. The power device, the speed reduction device and the two rocker arms are arranged on the machine body. The power device comprises a motor and a driving gear, the motor is fixed on the machine body, and the driving gear is connected with an output shaft of the motor; the speed reduction device comprises a driven gear, a right output gear assembly and a left output gear assembly which are in transmission connection in sequence, and the driven gear is meshed with the driving gear; the two rocker arms are arranged in one-to-one correspondence with the right output gear assembly and the left output gear assembly to form a double-crank rocker mechanism. The bird-imitating aircraft fuselage can be used as a bird-imitating aircraft fuselage to provide flight power for an aircraft, a double-crank rocker mechanism is adopted, the phase difference possibly generated during wing flapping is eliminated, meanwhile, the flight stability is improved, the whole mechanism is designed to be lightweight, and the weight and abrasion of the aircraft are reduced to a great extent.
