Embodiment Construction
[0030] The present invention is a mobile auxiliary flapping-wing drive mechanism based on an external meshing planetary gear reducer, which includes a frame, a motor, a parallel gear reducer, a planetary gear reducer and a connecting rod rocker arm mechanism.
[0031] Frame 1 is a left-right symmetrical overall mechanism, with the direction facing the nose as the front, there is a fixed hole on the upper part of the frame front, the axis of the fixed hole is perpendicular to the surface where it is located, and frame 1 is connected to the flapping wing aircraft through the fixed hole body threaded or pinned. The frame has rocker shaft holes 1E 1E', motor mounting holes 1A, limiter block mounting holes 1B 1B', cover plate mounting holes 1C and drive shaft holes 1D through the front and rear. The holes are symmetrically arranged and the axes are parallel. Among them, the four motor installation holes 1A are distributed in a cross; there are two symmetrical rocker shaft holes 1E,...

The present invention provides a mobile auxiliary flapping wing drive mechanism based on an external meshing planetary gear reducer, including a frame, a motor, a parallel gear reducer, an external meshing planetary gear reducer, a cover plate and a moving auxiliary link rocker mechanism, wherein , the motor is installed on the frame, driving the parallel gear reducer, the external meshing planetary gear reducer is installed in the inner space formed by the lower half of the frame and the cover plate through the crank shaft hole and the transmission shaft hole, and the parallel gear reducer passes through the transmission The shaft drives the external meshing planetary gear reducer, and the external meshing planetary gear reducer drives the flapping wing by connecting the moving secondary link rocker mechanism through the crank. In the present invention, a planetary gear reducer is used for deceleration and a moving auxiliary link rocker mechanism is used for transmission, and the transmission efficiency is high and relatively stable; the design structure is compact and the parts are few, which greatly improves the flight reliability of the aircraft.
Description
technical field [0001] The invention relates to a flapping-wing driving mechanism, which can be applied to a miniature flapping-wing aircraft. Background technique [0002] Compared with fixed-wing aircraft, micro-orthopting-wing aircraft can make flight more flexible and efficient by imitating the movement of birds, and can be widely used in various military and civilian fields. Since the flapping wing aircraft mainly generates lift and forward force through the active movement of the wings, how to reasonably design the flapping wing drive mechanism to make the flight aerodynamic efficiency and reliability higher has become the focus of research. [0003] The current flapping wing drive mechanism mainly has the following types: [0004] China Patent Authorization Announcement No. CN102229359B, titled as an invention patent of a cylindrical cam flapping wing drive mechanism, discloses a cylindrical cam flapping device that realizes a preset flapping law through the trajecto...
