The invention relates to the technical field of unmanned aerial vehicle equipment, in particular to a single-tilt control mechanism for a coaxial dual-rotor unmanned aerial vehicle. The single-tilt control mechanism comprises an adjusting assembly, a first servo motor and a second servo motor. The adjusting assembly and a main shaft of the coaxial dual-rotor unmanned aerial vehicle are coaxially arranged. A swash plate of the adjusting assembly is installed on the main shaft through a fisheye bearing. The connecting piece is installed on the side wall of the swash plate. One end of the ball head pull rod is connected with the connecting piece, and the other end is connected with the paddle. The first servo motor and the second servo motor are symmetrically arranged along the axis of the main shaft. The first servo motor and the second servo motor are installed on the main shaft through fixing frames. The output end of the first servo motor and the output end of the second servo motor are connected with the side wall of the swash plate through connecting rods. According to the single-tilt control mechanism for the coaxial dual-rotor unmanned aerial vehicle, periodic variable pitch control over the rotors is achieved, the complexity of a dynamic model of the unmanned aerial vehicle is reduced, and aerodynamic interference between the dual rotors is reduced.
本发明涉及无人机设备技术领域,具体涉及一种用于共轴双旋翼无人机的单倾斜操纵机构。该单倾斜操纵机构包括调节组件、第一伺服电机和第二伺服电机。调节组件与共轴双旋翼无人机的主轴同轴布设。调节组件的斜盘通过鱼眼轴承安装在主轴上。连接件安装在倾斜盘的侧壁上。球头拉杆的一端与连接件相连,另一端与桨叶相连。第一伺服电机和第二伺服电机沿着主轴的轴线呈对称布设。第一伺服电机和第二伺服电机均通过固定架安装在主轴上。第一伺服电机的输出端和第二伺服电机的输出端均通过连杆与倾斜盘的侧壁相连。该用于共轴双旋翼无人机的单倾斜操纵机构实现了对旋翼的周期变距控制,降低了无人机动力学模型的复杂度,减少了双旋翼之间的气动干扰。
