Cylindrical cam universal joint type bird imitation flapping wing flight device

Abstract

The invention discloses a cylindrical cam universal joint type bird imitation flapping wing flight device, and belongs to the field of bird imitation robots. The bird imitation flapping wing flight device comprises a base, wing rods symmetrically distributed on the two sides of the base, and flapping wings linked with the wing rods. A cylindrical cam is arranged in the middle of the base. A largebelt wheel is fixed to the upper portion of the cylindrical cam. A driving motor is slidingly fixed to the middle of the base. An output shaft of the driving motor is connected with a small belt wheel. The large belt wheel is connected with the small belt wheel through a belt. A universal joint connecting rod, a universal joint, a first spring rod, a spring, a second spring rod and a miniature motor are sequentially arranged between the cylindrical cam and each wing rod. The cylindrical cam is driven by the driving motor rotate, then the universal joints and the wing rods are driven to move, and the flapping wings flap up and down; by rotating the miniature motors, the flapping wings turn, and the lift force borne during flight is improved. The bird imitation flapping wing flight device issimple in structure, safe, reliable, high in stability, capable of effectively improving the flapping wing flight efficiency and particularly suitable for flight under strong wind, strong breeze andother environments.

Description

technical field [0001] The invention relates to the field of flapping-wing robots, in particular to a cylindrical cam universal joint type bird-like flapping-wing flying device. Background technique [0002] The bird-like flapping wing robot can imitate the flying style of birds in nature, and achieves flight by flapping its wings periodically. During the flapping process, the wings will open or close to achieve exhaust or joyride. Most of the existing bird-like flapping-wing robots mainly adopt crank-link mechanism, crank-slider mechanism, crank-gear mechanism and the like. Although the structure of the above-mentioned bird-like flapping wing robot mechanism is simple, it often needs to rotate a circle to realize one up and down motion of the flapping wing, and its movement efficiency is low. In addition, most flapping wings do not fully consider the principle of driving and exhausting, so the resistance during the swinging process of the flapping wing is relatively large,...
