Embodiment Construction

[0033] The DC motor 2 drives the crank 9 to move in a circle, and the connecting rod 10 drives the pin shaft 11 to move up and down in the vertical plane. The pin shaft is limited in the guide plate and can only move up and down along the groove in the guide plate.

[0034]The pin shaft 11 and the elastic connecting rod 7 are connected together, and when the pin shaft 11 moves up and down along the guide groove, it drives the elastic connecting rod 7 to reciprocate.

[0035] The elastic connecting rod 7 drives the flapping mechanism 3 of the wings to reciprocate around the wing rotation axis 17 to realize flapping of the wings up and down.

[0036] The cam 13 and the crank 9 rotate simultaneously under the drive of the DC motor, and both have the same rotation frequency and fixed phase difference. When the cam rotates, it drives the cam push rod 15 to reciprocate up and down, and the upper point of the cam push rod and the wing telescopic mechanism , Connected by a steel w...

Abstract

Having evolved over thousands and millions of years, birds are endowed with very excellent flying ability and their wings have terrific vehicle agility. A routine aircraft is mostly a fixed or rotor craft and cannot produce enough lift force at low Reynolds number to maintain balance. When the size is reduced to a certain level, a series of problems will appear. However, birds are outstanding flyers at low Reynolds number. Thus, an ornithopter imitating birds will certainly be the inevitable choice of future miniature air vehicles. Flight mode of bats is different from that of general birds. When bats flap their wings up and down, wingspan area is adjusted by folding and spreading wings to provide the lift force during flight. Therefore, on one hand, the single driving link flapping-wing flying robot space mechanism imitates up-down flapping of bats; and on the other hand, shrinking of bat wings is imitated. In addition, in comparison with other bat-imitating flying robots, the flapping-wing aircraft which imitates bat flight by the use of a single driving link has characteristics of light weight, strong vehicle agility and the like.

Description

technical field [0001] This patent relates to a space mechanism of a bionic flapping-wing flying robot, in which flapping and stretching of wings are simultaneously driven by an original moving part. technical background [0002] Thousands of years of natural evolution have given birds and bats the ability to fly with great dexterity. Modern aircraft with practical application performance mostly adopt fixed-wing structure or rotary-wing structure, and its movement flexibility is significantly different from the flapping flight of birds or bats. The flapping-wing aircraft has broad application prospects in modern national defense, exploration, and search and rescue, and it is also a necessary experimental platform for the development of flapping-wing flight aerodynamics. [0003] Improving the power coefficient per unit mass of the system is one of the key technical indicators for designing a flapping-wing aircraft. The invention proposes a bat-like flapping-wing flying rob...
