The invention relates to the technical field of unmanned aerial vehicles, and discloses a rotor wing tilting mechanism which comprises a connecting shaft, a connecting seat, a first driving device, apower device, a rotor wing and a transmission assembly. On the basis, the unmanned aerial vehicle can be switched between a multi-rotor mode and a fixed-wing mode through rotation of the connecting seat, the two modes can share one rotor wing and one motor, the structure of the whole vehicle is simplified, the weight of the whole vehicle is reduced, and thus the endurance time is prolonged; besides, the transmission assembly and the connecting seat form linkage, blades can be driven to rotate, the blade angles of the blades are changed, and thus the attack angles of the blades are changed, theunmanned aerial vehicle is kept within a good attack angle range in a fixed wing mode and a multi-rotor wing mode, a good lift coefficient is obtained, power consumption is further reduced, and energy consumption is optimized. In addition, the invention further discloses an unmanned aerial vehicle, and the unmanned aerial vehicle comprises wings and the rotor wing tilting mechanism.
本发明涉及无人机技术领域,公开了一种旋翼倾转机构,其包括连接轴、连接座、第一驱动装置、动力装置、旋翼以及传动组件。基于此,无人机通过连接座的转动可实现在多旋翼模态和固定翼模态之间切换,两种模态可共用一套旋翼和电机,简化了整机结构,减少了整机的重量,从而延长了续航时间;另外,使传动组件与连接座形成联动,可带动桨叶转动并改变其桨叶角,从而改变桨叶的迎角,使得无人机在固定翼模态和多旋翼模态下均保持在较佳的迎角范围,从而获得较优的升力系数,进一步减少了耗电量,优化了能耗。另外,本发明还公开了一种包括无人机,其包括机翼和上述的旋翼倾转机构。
