Problems solved by technology
In this scheme, the frictional resistance between the gears in the gear reduction group is large, and the energy loss is high. At the same time, due to the light weight and small size of the MAV, the energy of the carried power supply is limited, and the energy density of the current battery is limited. High energy loss is obviously not good for improving the endurance performance of the aircraft
In order to solve the above problems, someone proposed the design scheme of "electromagnetic drive connecting rod" and "motor driven rope transmission". In the scheme of "electromagnetic drive connecting rod", the rod structure is often in the harsh working state of friction and high-speed rotation The structure is prone to breakage, and the reliability is poor; in the "motor-driven rope transmission" scheme, although the high-speed rotating gear reduction group is removed, there are eccentric gears

The application discloses a flapping wing mechanism combining electromagnetic drive and rope transmission, which includes a rope drive mechanism, an electromagnetic drive mechanism and a pair of flapping wings. Through the technical solution of the present invention, energy absorption and energy storage can be buffered during the flapping wing movement, so as to achieve the effects of vibration reduction and energy consumption reduction, and at the same time can realize precise control of movement, avoiding the vibration caused by eccentric gear shaking in the traditional design. motion instability and asymmetry.
Description
technical field [0001] The invention relates to the field of micro-aircraft, specifically but not exclusively, to a flapping wing mechanism combining electromagnetic drive and rope drive. Background technique [0002] Since the 1990s, with the continuous maturity of traditional aircraft design technology and the great progress of microelectronics technology, the concept of micro air vehicle has been proposed and its rapid development has been promoted. Micro air vehicles are small in size, light in weight and strong in maneuverability. They have broad application prospects in national security and national economic construction, and can be used for investigation, exploration, and rescue assistance in complex environments. At the same time, as people continue to explore the flight principles of natural organisms (such as insects), bionic design is more and more applied to the field of micro-aircraft, and various bionic flapping-wing micro-aircraft that imitate the flight of i...
