The invention discloses a multi-rotor structure of a manned aircraft, belongs to the technical field of rotor diameter adjustment, and aims to solve the technical problems that when mechanical parts of a transmission structure are damaged, the exposed length of paddles cannot be stably guaranteed, and the stability of the aircraft during flight can be influenced. The output end of a telescopic electric cylinder drives a first fixing block to ascend through a connecting disc, and when a second fixing block is pulled by a rotating rod, a rotary vane is driven to slide on a bottom plate, so that the rotary vane retracts into a first mounting cavity from a through groove, and the diameter of the rotary vane is shortened; a motor in a motor shell drives a threaded rod to enable an inclined surface on one side of an extrusion block to extrude an inclined surface of a triangular block through a threaded hole in the extrusion block, so that the extrusion block extrudes the triangular block to move downwards through the inclined surface of the triangular block, the triangular block drives a sliding plate to move downwards in a sliding cavity in a second fixing shell, and the sliding plate drives a rubber pad to extrude a rotary vane to prevent a transmission mechanism from being damaged; and the diameter length between the rotary blades cannot be ensured, so that the flying state of the aircraft can be more stably packaged.

    一种载人飞行器的多旋翼结构,属于旋翼直径调节技术领域,为了解决传动结构机械部件在损坏的时候,无法稳定保证桨叶露出的长度,会影响飞行器飞行时的稳定性的技术问题,本发明通过伸缩电缸的输出端通过连接盘带动第一固定块上升,第二固定块在被转动杆拉动时,带动旋叶在底板上滑动,使旋叶从通槽缩入第一安装腔内,旋叶直径变短,电机壳内电机带动螺纹杆通过挤压块上的螺纹孔使挤压块一侧的斜面挤压三角块斜面,使得挤压块通过三角块的斜面将三角块挤压向下移动,三角块带动滑板在第二固定壳内滑腔向下移动,滑板带动橡胶垫挤压旋叶,防止传动机构损坏,无法保证旋叶之间直径长度,可以更稳定的包装飞行器在飞行时的状态。
