The embodiment of the invention discloses a micro bionic flapping wing mechanism, relates to the bionic flapping wing design technology, and can give consideration to both light weight and lift forceoutput. The mechanism comprises a transmission gear, a motor, a connecting rod, a rocker and a fixing frame for fixing the motor and a transmission mechanism, wherein a hollow cup motor is installed on the fixing frame, a small gear installed on a motor shaft is meshed with a large gear of the transmission mechanism, each large gear is hinged to a connecting rod, and the other end of each connecting rod is connected with a rocker. The mechanism is advantaged in that the flapping wing achieved through the crank and rocker mechanism not only can meet the high frequency requirement of the flapping wing aircraft, but also can generate enough lifting force in the vertical direction. The invention is suitable for the lightweight ornithopter.
Description
technical field [0001] The invention relates to the bionic flapping wing design technology, in particular to a miniature bionic flapping wing mechanism. Background technique [0002] Insects have perfect aerobatic technology, and their flight mechanism has always attracted the great interest of researchers. People's research on the principle of insect flapping wings provides a new idea for the design of flapping wing aircraft. Micro air vehicles are favored because of their small size, light weight, and good concealment. A more in-depth study of the flight mechanism of coleopteran insects can set a new banner for the development of future micro flapping wing aircraft. [0003] With the change of the natural environment, the long-legged bamboo elephant has evolved the optimal wing shape. During crawling, the flexible hind wings are folded under the hard forewings. When flying, the hind wings are slowly stretched out from under the forewings. During this period, it showed ext...
