Ornithopter flapping wing driving mechanism for science and education demonstration

Abstract

The invention discloses an ornithopter flapping wing driving mechanism for science and education demonstration, and belongs to the technical field of the science and education demonstration. The ornithopter flapping wing driving mechanism comprises a machine frame and a motional assembly mounted on the machine frame, wherein the motional assembly comprises a speed-reducing motor, a shaft coupler and an adjustable crank and rocker mechanism; the speed-reducing motor drives the adjustable crank and rocker mechanism to move through the shaft coupler; the adjustable crank and rocker mechanism comprises an adjustable crank and a pair of rocker assemblies; the adjustable crank comprises a transmission shaft, a crank, a slide block and an adjusting screw rod; the adjusting screw rod runs througha crank threaded hole and a slide block threaded hole in a screwing manner so as to limit the slide block in a strip-shaped sliding slot; each rocker assembly comprises a connecting rod and a rocker arm; the middle parts of the rocker arms are hinged to the machine frame through rotating shafts; the lower ends of the connecting rods are hinged to a short shaft of the adjustable crank; the upper ends of the connecting rod are hinged to the inner ends of the rocker arm. The ornithopter flapping wing driving mechanism has the characteristics of a long service life, convenience and safety in operation, simpleness, easy understanding, strong enlightenment, suitability for popularization and the like.

Description

technical field [0001] The invention relates to the technical field of science and education demonstration. Background technique [0002] As a new concept of bionic flight, the flapping wing aircraft has many characteristics such as small size, light weight, flexible use, and good concealment performance. It has broad application prospects in national defense and civilian fields. [0003] As far as the current situation is concerned, flapping wing aircraft, as a cutting-edge technological research, is still unknown to the public. Although there are some toy models of flapping wings on the market, the principle of flapping is still unknown to most people. However, there are very few flapping-wing aircrafts that are actually used for scientific and technological demonstration and teaching. Therefore, putting the flapping-wing bionic drive mechanism into scientific and educational demonstrations plays an extremely important role in motivating the masses to actively participate ...

[0003] As far as the current situation is concerned, flapping wing aircraft, as a cutting-edge technological research, is still unknown to the public. Although there are some toy models of flapping wings on the market, the principle of flapping is still unknown to most people. However, there are very few flapping-wing aircrafts that are actually used for scientific and technological demonstration and teaching. Therefore, putting the flapping-wing bionic drive mechanism into scientific and educational demonstrations plays an extremely important role in motivating the masses to actively participate in scientific and technological innovation, and can promote more research in related fields. go up a floor

[0004] Chinese patent publication number: CN102211667B, publication date April 3, 2013, the name of the invention is a two-stage parallel gear reduction flapping wing drive mechanism, the application discloses a two-stage parallel gear reduction flapping wing drive mechanism, Its shortcoming is that it uses two-stage transmission gears for motion transmission, which makes its mechanism life limited and the output speed is still high

However, in the prior art, there are only a handful of flapping wing drive mechanisms capable of continuously variable amplitude, and they are all relatively complicated.

Chinese Patent Publication No.: CN205098477U, open date March 23, 2016, the name of the invention is a differential amplitude flapping wing drive mechanism, the application discloses a differential amplitude variable flapping wing drive mechanism, the disadvantage of which is that the overall mechanism parts are relatively small. Many, the motion transmission is more complicated, which is not conducive to the basic science and education display equipment
