Abstract

The invention relates to the related field of unmanned aerial vehicles and discloses an unmanned aerial vehicle fan blade replacing device. The device comprises a box body, wherein a spline shaft is rotationally arranged in an upper end face of the box body, a movable spline sleeve is connected to an outer circle face of the spline shaft through a spline, and hinge rods symmetrical about the axis of the spline shaft are hinged to an outer circle face of the movable spline sleeve; an outer circle face of the spline shaft is in spline connection with a rotating spline sleeve, and the outer circle face of the rotating spline sleeve is hinged to auxiliary fan blades capable of being hinged to the rotating spline sleeve. According to the unmanned aerial vehicle fan blade replacing device, when high-altitude cutting operation is carried out through the unmanned aerial vehicle fan blades, the fan blades can be replaced in time in the process that the unmanned aerial vehicle is out of control due to the fact that the fan blades collide with foreign matter, so the unmanned aerial vehicle can fly normally, and the unmanned aerial vehicle is prevented from falling to the ground after being out of control; and a phenomenon that the unmanned aerial vehicle collides with pedestrians in the falling process is reduced.

Description

technical field [0001] The invention relates to the technical field related to drones, in particular to a fan blade replacement device for drones. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. [0003] The UAV fan blade has a certain cutting ability when it rotates at high speed, so it has the function of high-altitude cutting, but during the cutting process, the UAV fan blade is easy to collide with hard foreign objects, resulting in Damaged, so that it is easy to cause the drone to lose control. When the drone is falling, the fan blades are still rotating, which is easy to cause damage to nearby pedestrians, thereby reducing the safety of nearby pedestrians, and the drone appears Loss of control can easily cause the UAV to fall too fast, which will easily lead to the scrapping of the UAV when it collides with the ground. Contents of the invention [0004] The fan blade rep...
