The invention discloses a rotor craft tilting structure which comprises a driving unit and a tilting unit, and the rear portion of the driving unit and the rear portion of the tilting unit are sequentially arranged in a cylindrical positioning pipe along a straight line. The tilting unit comprises a screw rod which is arranged in the positioning pipe and is linearly connected with the driving unit, a straight push rod is screwed on the screw rod through a nut, and the front end of the straight push rod extends out of the front end of the positioning pipe and is connected with a rotating base through a rotating joint; the rotating base is hinged to the upper end of a front end positioning seat located at the front end of the positioning pipe through a first rotating shaft, and the rotating base can rotate between an unfolded state and a closed state around the first rotating shaft under pushing of the straight push rod. According to the tilting structure of the rotor craft, the transmission mechanism is high in transmission precision and resistant to abrasion, and the problem that in the prior art, the transmission mechanism is poor in stability after being abraded is solved; according to the rotating base, the tilting angle can be accurately and conveniently controlled.
本发明公开了一种旋翼飞行器倾转结构,其包括驱动单元和倾转单元,驱动单元和倾转单元的后部依次沿直线布置在一个圆柱状的定位管中;倾转单元包括:设在定位管中的与所述驱动单元直线连接的丝杆,一直推杆通过螺母螺接在丝杆上,直推杆的前端伸出定位管前端并通过旋转关节与一个旋转底座连接,该旋转底座通过转轴一铰接于位于定位管前端部的前端定位座的上端,在直推杆的推动下旋转底座可以绕转轴一在展开状态和闭合状态之间旋转。本发明所述旋翼飞行器倾转结构,其传动机构传动精度高抗磨损,克服了现有技术的传动机构磨损后导致其稳定性差的问题;本发明所述旋转底座可以精准方便控制倾转角度。
