The invention discloses a connecting rod rotor head and an unmanned aerial vehicle, and belongs to the technical field of aircrafts. Theconnecting rod rotor head comprises a main shaft, a rotor seat arranged at the upper end of the main shaft, a rotor wing assembly rotatably arranged on the rotor wing seat, a swash plate assembly movably arranged on the main shaft in a sleeving manner, and a connecting rod assembly; the swash plate assembly drives the rotor wing assembly to rotate through the connecting rod assembly, the connecting rod assembly comprises a phase connecting rod, a phase rocker arm and a screw pitch connecting rod, the phase rocker arm is rotatably arranged on the rotor wing seat, and one end of the phase rocker arm is movably connected with the swash plate assembly through the phase connecting rod; and the other end of the phase rocker arm is movably connected with the rotor wing assembly through a screw pitch connecting rod. According to the connecting rod rotor head, the oblique transmission phenomenon in the screw pitch transmission process can be avoided, the transmission precision is improved, the course stability of an unmanned aerial vehicle is conveniently improved, and the service life of parts is prolonged.
本发明公开了一种连杆旋翼头及无人机,属于飞行器技术领域,连杆旋翼头包括:主轴;旋翼座,旋翼座设置在主轴上端;旋翼组件,旋翼组件可转动地设置在旋翼座上;倾斜盘组件,倾斜盘组件可活动地套设在主轴上;以及连杆组件,倾斜盘组件通过连杆组件驱动旋翼组件转动,连杆组件包括相位连杆、相位摇臂和螺距连杆,相位摇臂可转动地设置在旋翼座上,相位摇臂的一端通过相位连杆与倾斜盘组件可活动地连接,相位摇臂的另一端通过螺距连杆与旋翼组件可活动地连接。根据本发明的连杆旋翼头,能够避免螺距传动过程中的斜向传动现象,提高传动精度,便于提升无人机航向稳定性,延长零件实用寿命。
