The rotor wing structure comprises a base and two blades which are symmetrically arranged, one end of each blade is rotatably inserted into the base, the top of the base is provided with a through opening corresponding to the blade, a rotating rod is rotatably inserted into the base, the top of the rotating rod is fixedly connected with two balance rods which are symmetrically arranged, and the balance rods are fixedly connected with the rotating rod. The rotating rod is sleeved with a torsional spring, the two ends of the torsional spring are fixedly connected with the rotating rod and the base respectively, and the rotating rod is fixedly sleeved with a first bevel gear. A direction control mechanism of the unmanned helicopter is simplified, a complex swash plate linkage mechanism is omitted, and with the help of a balance rod inertia mechanism, the rotation speed periodic fluctuation is controlled through the inertia principle to achieve the direction control function; compared with a traditional swash plate linkage direction control mode, the mode has the advantages of being simple in structure, not prone to damage, light in weight, high in reliability and the like.

    本发明公开了一种无人机用旋翼结构,包括底座和对称对称设置的两个桨叶,所述桨叶的一端转动插设于底座内,所述底座的顶部设有与桨叶对应的通口,所述底座内转动插设有转杆,所述转杆的顶部固定连接有对称设置的两个平衡杆,所述转杆上套设有扭簧,所述扭簧的两端分别与转杆和底座固定连接,所述转杆上固定套接有第一锥齿轮。本发明简化了无人直升机的方向控制机构,省去了复杂的斜盘联动机构,在平衡杆惯性机构的帮助下,通过惯性原理控制转速周期性波动实现方向控制功能;相比传统的斜盘联动方向控制方式,该方式具有结构简单不容易损坏,质量轻,可靠性高等优点。
