Technical field

The invention relates to a nautical model structure, in particular to a multi-rotor aircraft model machine and a rudder assembly structure thereof.

Background technique

The steering gear of the existing multi-rotor aircraft model is usually fixed behind the main body of the motor, that is, the tail end of the rotor supporting the carbon tube, and the main body of the motor is located between the carbon tube and the steering gear.

This assembly method has the following drawbacks: First, the steering gear system increases the size of the aircraft model machine, and the structure is cumbersome, affecting the flight performance of the aircraft model machine; second, because the metal connecting shaft of the steering gear system is disposed on the carbon tube Between the main body and the motor body, when the aircraft model machine descends rapidly, most of the impact force of the aircraft model machine bracket is directly transmitted to the metal shaft, and a strong bending force is formed, so that the metal connecting shaft is easily broken, further making the aircraft model machine The cost and the highest value of the steering gear are vulnerable to external forces.

Summary of the invention

In view of this, the present invention provides an assembly structure of a model aircraft and its steering gear, and the steering gear is assembled in front to solve the above technical problem.

Embodiments of the present invention provide a steering gear assembly structure for use on an aircraft model machine. The aircraft model machine includes a carbon tube and a rotor motor system, the steering gear assembly structure being disposed between the carbon tube and the rotor motor system. The steering gear assembly structure includes: a first bracket fixedly connected to the motor system; a metal shaft sleeved in the carbon tube and fixed on the first bracket, the metal shaft passing the first The bracket is fixedly connected to the motor system; the second bracket is fixedly connected to the carbon tube and the first bracket; and the steering gear is fixed on the second bracket and fixedly connected to the first bracket.

The embodiment of the invention further provides a model aircraft comprising the above-mentioned steering gear assembly structure.

By adopting the above structure, the steering gear assembly structure can be disposed between the carbon pipe and the motor system, and the steering gear system can reduce the volume occupied by the aircraft model machine without occupying an extra volume. In addition, when the aircraft model machine falls faster, the impact force of the second bracket is directly transmitted to the carbon tube, and is not transmitted to the metal shaft, which greatly reduces the possibility that the main body of the steering gear is damaged by external force.
