Problems solved by technology

[0007] In order to overcome the fact that the cylindrical gear reduction mechanism used in the existing wing drive mechanism of the miniature flapping-wing aircraft has many deceleration stages, heavy weight, complex structure, no self-locking property, and the left and right asymmetric planar four-bar linkage mechanism cannot realize left and right wings. Symmetrical flapping problem, the present invention proposes a kind of miniature flapping wing aircraft wing driving mechanism

Embodiment Construction

[0022] This embodiment is a set of miniature flapping wing aircraft wing drive mechanism, which adopts a worm gear mechanism to convert the high speed of the motor into the required low speed of the wing drive mechanism. This embodiment includes a shaft frame 1, a micro motor 2, a worm screw 3, a worm gear 4, a worm gear shaft 5 and a crank 6, a spherical hinge 10, a connecting rod 7 and a rocker arm 8, and the worm gear reduction mechanism and the motor are symmetrical axes, through Pedestal 1, crank 6, connecting rod 7, and rocker 8 form a set of spatial four-bar linkages on both sides of the worm gear mechanism and the micromotor 2. When the worm gear 4 rotates, the crank 6 is driven by the worm gear shaft 5 to rotate together. Crank 6 drives rocking arm 8 to swing up and down through connecting rod 7 again, and then drives wing 11 to flutter up and down. The specific implementation process is:

Abstract

A drive mechanism for the wings of miniature ornithopter is composed of a worm-gear speed reducer and two sets of 4-connection-rod unit consisting of crank with one end fixed to the axle of worm gear, connection rod with one end linked to crank, and rocker arm linked between rocker arm and wing.

Description

technical field [0001] The invention relates to a drive mechanism for a wing of a micro-orthopter aircraft. Background technique [0002] Micro orpter is a kind of micro-aircraft. Micro-aircraft is an emerging technical field in recent years. It is generally believed that the basic indicators of micro-aircraft are: aircraft is a type of aircraft whose maximum size in all directions does not exceed 15 cm. In 20-60 minutes, the flight range reaches more than 10 kilometers, the flight speed is 30-60 kilometers per hour, it can carry 20 grams of payload and can complete the prescribed tasks. [0003] The miniature flapping-wing aircraft imitates the flight principle of birds. Through the up and down flapping of a pair of wings on both sides of the fuselage, it generates the lift required to support the weight of the body and the thrust to overcome the resistance of the forward flight. It has high aerodynamic efficiency and flexible maneuverability. It has a wide range of applic...
