The invention relates to a power device of an unmanned aerial vehicle and the unmanned aerial vehicle. A power device of the unmanned aerial vehicle comprises a main shaft, a motor, a steering engine and a rotor wing assembly. The spindle is fixed to the top of the unmanned aerial vehicle body. The motor is arranged on the main shaft, the steering engine and the rotor wing assembly are both in driving connection with the motor, and the steering engine and the rotor wing assembly can both rotate around the axial direction of the main shaft under driving of the motor. The rotor assembly comprises a propeller hub and blades, the propeller hub is in driving connection with the motor, and the blades are connected with the propeller hub. An output shaft of the steering engine is provided with a first gear, the propeller hub is provided with a second gear, when the flight direction is changed, the steering engine is started and drives the first gear to rotate, and the first gear and the second gear are in meshing transmission, so that the rotor wing assembly rotates by a certain angle, namely, the pitch angle of the propeller blades and the propeller pitch of the rotor wing assembly are adjusted. Thus, a traditional complex and heavy automatic inclinator control system can be replaced, the weight of the unmanned aerial vehicle can be reduced, the control precision of variable pitch is improved, and accurate variable pitch is achieved.
本申请涉及一种无人机的动力装置及无人机。无人机的动力装置包括主轴、电机、舵机以及旋翼组件。主轴固定于无人机本体的顶部。电机设于主轴,舵机以及旋翼组件均与电机驱动连接,在电机的驱动下,舵机以及旋翼组件均能够绕主轴的轴向转动。旋翼组件包括桨毂以及桨叶,桨毂与电机驱动连接,桨叶与桨毂连接。舵机的输出轴设有第一齿轮,桨毂设有第二齿轮,当飞行方向改变时,舵机启动并驱动第一齿轮转动,第一齿轮与第二齿轮啮合传动,使得旋翼组件转动一定角度,即调整桨叶的俯仰角,调整旋翼组件的桨距。如此,可取代传统复杂笨重的自动倾斜器操纵系统,有利于减轻无人机的重量,提高变距的控制精度,实现精准变距。
