Medium-sized training unmanned aerial vehicle capable of preventing fan blades from colliding

Abstract

The utility model belongs to the technical field of medium -sized training unmanned plane, concretely relates to a medium -sized training unmanned plane of fan leaf collision prevention, including unmanned plane fuselage, the outer wall of unmanned plane fuselage is installed four connecting frames, one end of connecting frame is installed with drive motor, the output of drive motor is connected with unmanned plane fan leaf, the bottom of unmanned plane fuselage is installed with two support frames, the bottom fixed connection of drive motor has the connecting column, the bottom fixed connection of connecting column has the limit stop piece. The utility model through with the connecting ring from the threaded column bottom sleeve connection on the outer wall of threaded column, with threaded connection sleeve and threaded column outer wall threaded connection, until threaded connection sleeve will connecting ring top resist against limit stop piece, to be able to install the protective cover in unmanned plane fan leaf bottom, then utilize the rubber strip on the protective cover and its outer wall can block before unmanned plane fan leaf contacts object, further avoid unmanned plane fan leaf direct contact with object to cause unmanned plane fan leaf damage.
