A flapping-wing driving mechanism of a flapping-wing aircraft for scientific and educational demonstration

Abstract

The invention discloses a flapping wing driving mechanism for science and teaching demonstration. The mechanism is composed of a rack, a speed reducing motor and an adjustable crank and rocker mechanism; and the rack is fixedly provided with the speed reducing motor by which the adjustable crank and rocker mechanism is driven to flap up and down at a certain frequency and amplitude. The flapping wing driving mechanism is compact in structure, simple in operation and capable of vividly and intuitively showing a flapping wing flapping way and greatly enriching the interestingness of science andteaching demonstration, and both the flapping frequency and flapping amplitude of the driving mechanism can be adjusted within a certain range.

Description

Technical field [0001] The invention relates to the technical field of science and education demonstration. Background technique [0002] As a new concept aircraft of bionic flight, the flapping-wing aircraft has many characteristics such as small size, light weight, flexible use and good concealment performance. It has a wide range of application prospects in national defense and civil fields. [0003] At present, as a cutting-edge technology research, flapping-wing aircraft is not well understood by the public. Although there are some flapping-wing toy models on the market, the flapping principle is still unknown to most people. The actual use of flapping-wing aircraft for scientific and technological display and teaching is even rarer. Therefore, the use of flapping-wing bionic drive mechanisms in science and education demonstrations plays an extremely important role in motivating the masses of people to actively participate in technological innovation, and can promote research ...

Problems solved by technology

[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
