The invention provides a limitable automatic folding propeller and a working method thereof. The limitable automatic folding propeller comprises a propeller hub, propeller bodies are mounted at the two ends of the propeller hub through bearings, and an automatic folding device is mounted in the propeller hub; the propeller hub comprises a propeller hub disc structure composed of an upper propellerhub disc and a lower propeller hub disc; the automatic folding device comprises an upper mounting disc and a lower mounting disc, the upper mounting disc is fixed to the lower portion of the upper propeller hub disc, the lower mounting disc is fixed to the upper portion of the lower propeller hub disc, a fixing column is arranged at the gravity center of the lower mounting disc, and the upper mounting disc and the lower mounting disc are fixedly connected through the fixing column; and the center of a coil spring is clamped on the fixing column, a rotating disc is clamped on the outer side ofthe coil spring, the middle of a coil is limited on the rotating disc and initially in a winding state, and two ends of the coil extend outwards to be limited on the propeller bodies. According to the limitable automatic folding propeller and the working method thereof, the folding process of the propeller is changed into automatic folding, extra mechanical or manual operation is not needed, themechanical structure is simple, and a large amount of manpower and material resources are saved.

    本发明提供了一种可限位的自动折叠螺旋桨及其工作方法,该装置包括桨毂,桨毂两端通过轴承安装有螺旋桨,所述桨毂内部安装有自动折叠装置;所述桨毂包括由上桨毂盘和下桨毂盘组成的桨毂盘结构;所述自动折叠装置包括上安装盘、下安装盘,上安装盘固定在上桨毂盘的下方,下安装盘固定在下桨毂盘的上方,下安装盘重心位置设置有固定住,上安装盘和下安装盘通过固定住固定连接;卷簧中心卡在固定柱上,旋转盘卡在卷簧外侧,线圈中部束缚于旋转盘,初始为缠绕状态,线圈两端外伸而出,束缚在螺旋桨上。本发明使螺旋桨的折叠过程改为自动折叠,而不需额外的机械或者人工操纵,机械结构相比较简单,节省了大量的人力物力。
