Three-dimensional flapping wing drive mechanism based on cross-axis hinge and conical rocker arm

Abstract

The invention provides a three-dimensional flapping wing driving mechanism based on a cross axis hinge and a conical rocker arm, which comprises a frame (1), a flapping driving mechanism (2) and a variable amplitude sweep servo mechanism (3). The flapping driving mechanism (2) comprises a flapping motor and a left flapping driving unit and a right flapping driving unit which are simultaneously linked with an output shaft of the flapping motor and are symmetrically arranged; the left flapping drive unit and the right flapping drive unit have the same structure and comprise gear reducers, conical sleeve rocker arms (2.4) and cross flutter shafts (2.5). The three-dimensional flapping wing driving mechanism based on the cross shaft hinge and the conical rocker arm can realize the complex motion of birds such as sweeping, varying amplitude and flapping with simple structure, and has high structural efficiency and high output power, high reliability and long service life, and is suitable forapplication in micro flapping-wing air vehicle.

Description

technical field [0001] The invention belongs to the technical field of design of a flapping-wing aircraft driving mechanism, and in particular relates to a three-dimensional flapping-wing driving mechanism based on a cross-axis hinge and a conical rocker arm. Background technique [0002] The micro flapping wing aircraft is a new concept aircraft that imitates the flight of birds. It has the advantages of small size, light weight, maneuverability and high efficiency. Since the lift and thrust of the flapping wing aircraft are provided by the flapping motion of the flapping wing, driving the flapping wing to obtain good aerodynamic efficiency, high reliability and good load characteristics has become a micro flapping wing. The key link in the development process of wing aircraft. [0003] The current flapping wing drive mechanism mainly has the following technical approaches: [0004] Chinese Patent Authorization Announcement No. CN201354146Y, a utility model patent titled ...
