Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to a wing structure of a bionic seagull-type flapping-wing unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles are the research focus of the military fields of various countries today. Miniaturized unmanned aerial vehicles are playing an increasingly important role in military reconnaissance due to their small size and easy penetration.

[0003] However, the current mainstream reconnaissance-type micro-UAVs mainly have two types of wing types: fixed-wing and rotary-wing. Their special aerodynamic flight mode has poor concealment and can be easily captured by the naked eye or radar.

[0004] Therefore, it is necessary to design a bionic flapping-wing UAV structure to solve the above technical problems. Summary of the invention

[0005] Aiming at the defect of poor concealment in the existing fixed-wing and rotary-wing reconnaissance UAV technologies, the present invention provides a bionic seagull-style flapping-wing UAV wing structure to solve the problem of poor concealment.

[0006] The technical solution of the present invention is as follows:

[0007] A bionic seagull-like flapping-wing UAV wing structure comprises a main wing, an aileron, a fuselage fixed structure, a transmission rod module, and a transmission gear module. Each side of the flapping-wing UAV wing structure is composed of a main wing, an aileron, a transmission rod module, and a transmission gear module, and the two sides are symmetrical along the central hole of the fuselage fixed structure.

[0008] Furthermore, the transmission rod module is composed of two sets of main wing transmission rods and aileron transmission rods. The two sets of main wing transmission rods and aileron transmission rods are symmetrical about the left and right sides of the central hole of the fuselage fixed structure, and their function is to balance the aerodynamic force of the wings on both sides during flight.

[0009] Furthermore, the transmission gear module is composed of two gears, and the two gears are symmetrical on the left and right sides of the center hole of the fuselage fixing structure. The function of the transmission gear module is to convert the power of the UAV into mechanical energy through the transmission rod module and the transmission gear module and transmit it to the wing, so that the wing vibrates up and down to provide lift for the UAV.

[0010] Furthermore, the fuselage fixing structure has five through holes on its surface, including a central hole at the bottom, and four side holes, two on each side, which are symmetrical about the central hole. The side holes are located at an upper position, and the two holes on one side form an upper and lower array, wherein the central hole at the bottom is used to transmit the kinetic energy of the UAV to the transmission gear module; the upper two holes of the four side holes are used to connect and fix the main wings on both sides; and the lower two holes of the four side holes are used to connect and fix the main wing transmission rods.

[0011] Furthermore, the two gears included in the transmission gear module are meshed with each other and connected to the cylindrical hinge of the fuselage fixed structure. The connection positions are located in the side holes on the lower left and right sides of the fuselage fixed structure. The function of the transmission gear module is to transmit the kinetic energy of the drone to the transmission rod module and the wing.

[0012] Furthermore, the transmission rod module includes a main wing transmission rod having one end connected to the transmission gear module cylindrical hinge, and the other end connected to the main wing cylindrical hinge; the transmission rod module includes an aileron transmission rod having one end connected to the main wing cylindrical hinge, and the other end connected to the aileron cylindrical hinge. The function of the transmission rod module is to pull the wing to vibrate.

[0013] Furthermore, one end of the main wing is connected to the main wing transmission rod cylindrical hinge in the transmission rod module, and the other end is connected to the aileron cylindrical hinge.

[0014] Furthermore, the aileron end is connected to the main wing cylindrical hinge, and the aileron end is connected to the aileron transmission rod cylindrical hinge at a point where the length of the aileron end accounts for 1 / 6 of the total aileron length.

[0015] The wing composed of the main wing and the ailerons vibrates and beats the air to provide lift for the drone.

[0016] The beneficial effects of the present invention are as follows:

[0017] Compared with the existing fixed-wing and rotary-wing reconnaissance UAV technologies, the present invention provides a bionic flapping-wing UAV wing structure, which improves the concealment of the reconnaissance UAV. BRIEF DESCRIPTION OF THE DRAWINGS
