A steering engine (10), a gear box (7), a motor mounting seat (4) and a brushless motor (3) are sequentially arranged from bottom to top, in the gear box (7), a first bevel gear (5) and a second bevel gear (6) are coaxially arranged on a shaft rod (11), the first bevel gear (5) and the second bevel gear (6) are meshed with a third bevel gear (9), and the third bevel gear (9) is connected with the steering engine (10); the motor mounting seat (4) is arranged at the arc-shaped end of the gear box (7); and the torsion plate (8) is arranged outside the motor mounting seat (4). Torsion is counteracted through cooperation between the gear set and the torsion plate, and the problem that the flying stability of double rotors is poor is solved.

Description

Technical Field

[0001] The utility model relates to an anti-torque motor seat of a transverse double-rotor UAV. Background Art

[0002] As a unique and challenging aircraft design, the mechanical characteristics of the transverse twin-rotor drone bring some inherent limitations. Due to the mechanical defects of the transverse twin-rotor drone, when performing pitching motion, that is, when the drone rotates around its left and right axis (Y axis), this design faces a significant problem: if both rotors tilt forward or backward at the same time, a torque on the Y axis is generated that is difficult to offset.

[0003] If the irreversible torque generated on the Y-axis is not properly handled, it will significantly affect the drone's flight stability and may even cause loss of control. To address this issue, existing technology uses a "V-shaped" fuselage to lower the drone's overall center of gravity, thereby mitigating the impact of torque on flight stability. This design enhances the structural stability of the aircraft and utilizes physical principles to mitigate the impact of torque on flight stability. While this can counteract the torque generated by rotor tilt, it does not completely resolve the problem of rotor tilt caused by practical principles.

[0004] In summary, the horizontal layout of the drone results in an irreversible torque on the Y-axis during pitch motion, affecting flight stability. Summary of the Invention

[0005] The purpose of the utility model is to solve the problem that the horizontal layout of the UAV may cause the two rotors to tilt forward or backward at the same time during pitch movement, generating a moment on the Y-axis that is difficult to offset and affecting the flight stability, and to provide an anti-torque motor mount for a horizontal twin-rotor UAV.

[0006] The above purpose is achieved through the following technical solutions:

[0014] Furthermore, the motor mounting base includes a horizontal plate and two side plates, and the two ends of the horizontal plate are respectively vertically connected to a side plate;
