[0003] In the prior art, in order to realize the highly symmetrical flapping action during the design of the flapping wing robot, transmission gears are arranged at both ends of the body, and the final main wing flapping is driven through the transmission between multiple gears to realize the flight action. However, in use, a separate steering structure needs to be used between the main wing and the aileron, such as a rudder machine. The rudder machine itself has a certain weight, and when it is installed at the free end of the main wing, it will cause uneven weight distribution of the entire wing surface, affecting the flight efficiency and maneuverability, increasing the weight of the free end of the main wing, and also increasing the angle adjustment between the main wing and the aileron, which will increase the complexity of the system, meaning that the precise control of the rudder machine is the key to realizing the coordinated movement of the main wing and the aileron.

[0030] As Figure 1 and Figure 2 shown, a transmission mechanism of an eagle-imitating flapping wing robot includes an assembly plate 2 and flapping wing mechanisms 4 symmetrically arranged on both sides of the assembly plate 2, the flapping wing mechanism 4 includes a main rod 41, a connecting rod 42 and an auxiliary rod 43, one end of the main rod 41 is rotatably connected to the assembly plate 2, one end of the connecting rod 42 is connected to the assembly plate 2 and is arranged in parallel with the main rod 41; the auxiliary rod 43 is rotatably connected to the ends of the main rod 41 and the connecting rod 42 away from the assembly plate 2; wherein the connecting rod 42 and the auxiliary rod 43 swing back and forth relative to the assembly plate 2 to drive the auxiliary rods 43 on both sides of the assembly plate 2 to expand or fold synchronously. The main rods 41 are symmetrically arranged on both sides of the assembly plate 2, and the number thereof can be adjusted as required, for example, two groups or three groups of main rods 41 are arranged on each side of the assembly plate 2, and correspondingly, the connecting rods 42 are arranged according to the number of groups of main rods 41 to achieve multiple groups of common flapping movements. In the present application, one group of main rods 41 is preferred. The connecting rod 42 is parallel to the main rod 41 and together forms a parallel movement pair, so that when the main rod 41 and the connecting rod 42 rotate together, the auxiliary rod 43 at the end thereof expands or folds, thereby realizing the flapping action of the flapping wing robot without using the original rudder motor drive, so as to avoid the different installation positions of the rudder motor, causing uneven stress on both sides of the flapping wing mechanism 4 and the assembly plate 2, affecting the overall structural stability, and the rudder motor also increases the driving complexity, requiring debugging programs and parameters, greatly improving the system difficulty of design.
[0031] Specifically, the driving assembly 1 is arranged on one side of the assembly plate 2, and is used to drive the main rod 41 or the connecting rod 42 to rotate, so as to drive the auxiliary rod 43 to unfold or fold. The driving assembly 1 comprises a motor, a circuit board and a battery. The battery supplies power for the motor and the circuit board. The circuit board adjusts the rotating speed of the motor. The output shaft of the motor can drive the main rod 41 to swing or drive the connecting rod 42 to swing, that is, the main rod 41 and the connecting rod 42 can swing synchronously, and the auxiliary rod 43 can be driven to realize the unfolding and folding beating action. In the present application, the motor is preferably used to drive the main rod 41 to swing.
[0032] As shown in Figure 1 and Figure 2 , as an embodiment of the present application, the shell of the motor is fixed to the assembly plate 2, the output shaft of the motor penetrates the assembly plate 2 and is insertedly fixed to the end of the main rod 41, so that the rotation of the output shaft of the motor can drive the main rod 41 to rotate. The circuit board adjusts the rotating angle range of the motor, so as to adjust the swing range of the main rod 41. The corresponding motor is arranged on the main rod 41 arranged symmetrically.

That is, the output shaft of the assembly plate 2 is provided with a driving gear meshing with the swing piece 33. The driving gear and the driven gear are meshed with each other to realize the swing. The connecting part 34 is fixed to one side of the swing piece 33 by a latch, or the connecting part 34 is integrally formed on one side of the swing piece 33. When the swing piece 33 swings, the connecting part 34 swings back and forth, so as to drive the main rod 41 to swing.
