Problems solved by technology

[0006] 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

[0021] 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 turbine 4, a turbine shaft 5, 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. 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 micro-motor 2. When the turbine 4 rotates, the turbine shaft 5 drives the crank 6 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

(1) Technical field [0001] The invention relates to a drive mechanism for a wing of a micro-orthopter aircraft. (2) Background technology [0002] Miniature flapping-wing aircraft is an emerging technical field in recent years. It is usually defined as: the dimension in each direction does not exceed 150mm, and the weight is 10-100g. It has the characteristics of high aerodynamic efficiency, flexible maneuvering, wide application range, and strong concealment when performing tasks, so it has high military and civilian application value. [0003] The power of the most commonly used wing drive mechanism of a micro-orthopter is a micro DC motor. The rated operating speed of this type of motor is usually around 300-400 rpm, and the wing flapping frequency required for the flight of an orthopter is between About 10 times per second, so a reduction mechanism is required to convert the high speed of the motor into the low speed required for the flapping of the wings, and the reduc...
