The invention discloses a differential gear train mechanism for timely speed regulation of a multi-rotor unmanned aerial vehicle, whichbelongs to the technical field of unmanned aerial vehicles. The differential gear train mechanism capable for timely speed regulationofa direct-drive multi-rotor unmanned aerial vehiclecomprises an engine (or a motor), and differential transmission mechanisms and propellers (or rotors), wherein a power output shaft of the engine (or the motor) is connected with a power input shaft of the differential transmission mechanism, and thepropeller (or therotor) is unidirectionally or fixedly connected to the power output shaft of the differential transmission mechanism, so that pitching, rolling, yawing and other motions of the unmanned aerial vehicle can be realized under the condition that the rotating speed of the engine (or the motor) is not changed. The problem that the rotating speeds of multiple engines of an existing direct-drive multi-rotor unmanned aerial vehicle are difficult to keep consistent is effectively solved, the influence of the coupling of position changes and posture changes in an under-actuated system of the unmanned aerial vehicle on a control structure is greatly reduced, control is more accurate, and the flexibility and the wind disturbance resistance of the unmanned aerial vehicle are improved.

    一种多旋翼无人机适时调速的差动轮系机构,属于无人机技术领域。本发明的直驱多旋翼无人机可适时调的差动速轮系机构,其组成包括发动机(或电机)、差速传动机构及螺旋桨(或旋翼);所述的发动机(或电机)的动力输出轴与差速传动机构的动力输入轴连接,所述的差速传动机构的动力输出轴上单向或固定连接螺旋桨(或旋翼),可以实现在不改变发动机(或电机)的转速的情况下,实现无人机的俯仰、翻滚、偏航等运动。本发明有效解决了现有直驱多旋翼无人机存在的多台发动机转速难于保持一致的问题,大大降低了无人机的欠驱动系统中位置变化与姿态变化的耦合性对控制结构的影响,使控制更加精确,提高无人机的灵活性及抗风扰的能力。
