Problems solved by technology
However, the defect of this patent application is that although a driving shaft and corresponding motor are omitted, the overall mechanism is too complicated, which is not conducive to miniaturization of the flapping wing aircraft, and the cost is relatively high
The defect of this patent is: the safety factor is not high when manned, and it is easy to cause accidents
The defect of this patent is: can not realize high-frequency flapping movement

Embodiment Construction
[0012] As shown in Figures 1 to 3, there is a square hole 14 in the middle of the fuselage 13 of the flapping-wing aircraft. The follower of the constant-width cam mechanism is in the shape of a rectangular frame 2; the inside of the constant-width cam mechanism is a cam 6, and the distance between any two parallel tangents on the contour of the cam 6 is equal to the width inside the rectangular frame 2. A key groove 8 is machined in the cam 6 of the constant-width cam mechanism. The engine 7 is fixed inside the fuselage 13, and the engine 7 is connected to the key 5 in the constant-width cam mechanism through the rotating shaft 15. That is, one end of the rotating shaft 15 is connected to the engine 7 and the other end is connected to the key 5. The keyway 8 is matched with the key 5, and an appropriate gap is left between the upper surface of the key 5 and the bottom surface of the keyway 8. The upper part of the constant-width cam mechanism is connected with the connecting...

The invention discloses a miniature ornithopter. The middle of a body is provided with a square hole; an aequilate cam mechanism is arranged in the square hole; a cam is arranged inside the aequilate cam mechanism; and the distance between the arbitrary two parallel tangents on a cam contour line is equal to inside width of a rectangular frame; an engine is fixed inside the body; one end of a rotating shaft is connected with the engine, while the other end is connected with a key; the upper part of the aequilate cam mechanism is connected with a connecting rod through a bolt; two sides of theconnecting rod have distance from the outer wall of the body; the tail end of the connecting rod is connected with a bearing support through a bolt; a sliding bearing passes through a round hole and is tightly combined with a wing; the upper surface on the tail end of the wing is connected with a spring, and the other end of the spring is connected with the inner wall of the bearing support; and the lower surface on the tail end of the wing is also connected with a spring, and the other end of the spring is connected with the inner wall of a bearing cover. The miniature ornithopter is integrated with functions of lift force, hovering, boosting and controlling, can carry out distant aviation with less energy, and has the advantages of high efficiency, high maneuverability, low noise and vertical take-off and landing capability.
Description
Technical field [0001] The invention relates to the technical field of aircrafts, and is specially designed for a small flapping wing aircraft, which can be widely used in military, toys, sports and entertainment activities, agriculture and forestry and other fields. Background technique [0002] At present, there are some similar products at home and abroad, each with its advantages and disadvantages. For example, the patent application with the publication number CN101249887 and the name "A kind of aileron rotating retractable flapping wing device" discloses the aileron rotating retractable flapping wing wing and the corresponding driving device. Among them, according to the wing along the wingspan The direction is divided into two parts: the main wing and the aileron. The leading edge framework of the main wing and the leading edge framework of the aileron are connected by hinges. The two can rotate relative to each other in the plane of the wing with the hinge as the axis, so...
