The invention discloses a single-drive foldable coaxial propeller device which comprises a fairing, a motor, an electromagnetic clutch, a commutator, a front blade and a rear blade, the motor is of a double-output-shaft structure, a front-end output shaft of the motor is connected with the front blade, and a rear-end output shaft of the motor is connected with the driving end of the electromagnetic clutch; the driven end of the electromagnetic clutch is connected with the input end of the reverser through a transmission shaft, and the output end of the reverser is connected with the rear paddle through a propeller shaft, so that the rotation directions of the rear paddle and the front paddle are opposite; the tail end of the propeller shaft is connected with a rear propeller hub, the rear propeller blades are rotatably connected to the rear propeller hub, a rear propeller blade reset piece is arranged between the rear propeller hub and the rear propeller blades, and the two ends of the rear propeller blade reset piece are connected with the rear propeller hub and the rear propeller blades respectively. The single-drive foldable coaxial propeller device has the advantages that the structure is simple, the operation is stable, the control is easy, the propulsive force of the aircraft can be greatly improved during acceleration propulsion, the navigation resistance can be reduced during cruising, and the navigation efficiency is improved.

    本发明公开了一种单驱动可折叠共轴螺旋桨装置,包括导流罩、电机、电磁离合器、换向器、前桨叶和后桨叶,电机为双输出轴结构,电机的前端输出轴与前桨叶连接,电机的后端输出轴与电磁离合器的主动端连接,电磁离合器的从动端通过传动轴与换向器的输入端连接,换向器的输出端通过螺旋桨轴与后桨叶连接并使得后桨叶与前桨叶的旋转方向相反;螺旋桨轴的末端连接有后桨毂,后桨叶可转动地连接在后桨毂上,后桨毂与后桨叶之间设有后桨叶复位件,后桨叶复位件的两端分别与后桨毂和后桨叶相连。采用本发明,具体结构简单、运行稳定、易于控制,既能在加速推进时大大地提升航行器推进力,又能在巡航时减小航行阻力,提高航行效率的优点。
