Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The two-stage parallel gear reduction flapping wing drive mechanism of the present invention includes a frame, a motor, a two-stage parallel gear reducer and a four-bar linkage mechanism.

[0026] Frame 1 is a left-right symmetrical overall structure, and the bottom surface and the front upper part have fixing holes with axes perpendicular to the surface respectively, and are connected with the flapping-wing aircraft fuselage frame 7 by said fixing holes, and the connection mode is a pin connection or a threaded connection. The frame 1 has a motor 2 mounting hole 1A, a transmission shaft hole 1B and a crank shaft hole 1C in the front and rear directions. There are two symmetrical rocker shaft holes 1D and 1D' above the crank shaft hole 1C, and their axes are parallel to the axes of the aforementioned three holes. In addition, the frame 1 also ha...

Abstract

The invention discloses a flapping wing driving mechanism of two-level parallel gear reduction. The mechanism comprises a rack, a motor, a two-level parallel gear reducer and a four-bar mechanism, wherein a micro motor is fixed on the rack, which drives the two-level parallel gear reducer and the two rocker arms of the four-bar mechanism and converts the high-speed rotation of the micro motor into the up-down flapping of the rocker arm of the four-bar mechanism at proper frequency. The flapping wing driving mechanism disclosed by the invention has the advantages of simple structure, light weight, small space, high reliability, long service life and the like, and is suitable for micro flapping wing aircraft.

Description

technical field [0001] The invention relates to a flapping wing drive mechanism. 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, flexible use, and high efficiency. Since the lift and thrust of the flapping-wing aircraft are provided by the flapping wings that flutter up and down, driving the flapping wings makes the flapping-wing aircraft obtain good aerodynamic efficiency, high reliability and good load characteristics. An important part of the overall performance of the flapping wing aircraft. This makes the design of the flapping-wing drive mechanism a key link in the development of the miniature flapping-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 the flapping mechanism of a mec...
