The invention relates to an unmanned helicopter structure, in particular to an unmanned helicopter automatic inclinator structure which comprises a spherical hinge matched with a rotor shaft and synchronously rotating with the rotor shaft. A movable ring and a fixed ring are arranged on the outer side of the spherical hinge, a transmission shaft hole used for being connected and matched with the rotor shaft is longitudinally formed in the spherical hinge, the movable ring is arranged outside the spherical hinge, an inclination angle guide structure is arranged between the movable ring and the spherical hinge to adjust the inclination angle of the movable ring relative to the spherical hinge, and the movable ring and the spherical hinge are connected through the inclination angle guide structure to rotate synchronously; the fixed ring and the movable ring coaxially sleeve the inclination angle guide structure and rotate relative to the inclination angle guide structure, the fixed ring is further connected with a plurality of driving mechanisms, and the driving mechanisms are used for applying force to the fixed ring so as to adjust the inclination angles of the fixed ring, the inclination angle guide structure and the movable ring. The rotor shaft is prevented from being damaged by impact load, synchronous rotation of the movable ring and the spherical hinge is achieved, the service life of the rotor shaft is prolonged, and the maintenance cost of the inclinator is greatly reduced.

    本发明涉及无人机结构,具体涉及一种无人直升机自动倾斜器结构,包括与旋翼轴配合且同步转动的球铰,球铰外侧设有动环和不动环,球铰上纵向设置有用于连接配合旋翼轴的传动轴孔,球铰的外部设置动环,动环与球铰之间设有倾角导向结构以调节动环相对于球铰的倾斜角度,且动环与球铰通过倾角导向结构连接以同步转动;不动环与动环同轴套设在倾角导向结构外部并与倾角导向结构相对转动,不动环还连接若干驱动机构,驱动机构用于对不动环施力以调节不动环、倾角导向结构及动环的倾斜角度。本发明避免了冲击载荷导致旋翼轴的损坏,同时实现动环与球铰的同步转动,延长了旋翼轴的使用寿命,大大减小了倾斜器的维护成本。
