Problems solved by technology

The first method needs to use additional nuts or propeller clamps, which increases the weight and complexity, and makes the work of replacing the propeller more complicated; the second method is suddenly locked due to the huge inertia of the high-speed rotating blades. It will still cause the thread to unscrew and cause the propeller to shoot

Embodiment Construction

[0018] Describe in detail below in conjunction with accompanying drawing.

[0019] As a device for locking the propeller of the drone and its control method, the present invention realizes the locking of the propeller of the drone in an emergency, and will be described below in conjunction with specific implementation examples.

[0020] Such as figure 1 Shown is the control process steps of locking the UAV propeller. The autopilot monitors the flight status of the UAV in real time. When there is a situation in the operation of the UAV, it will output the locking control command to the propeller of the UAV, start the locking early warning device, and perform friction braking on the rotating motor. The rotation speed of the rotating motor is monitored. When the speed decreases to 0, the propeller is locked and fixed; after the condition of the drone is released, the locked and fixed state of the propeller is released through the control command of the remote control, that is, ...

Abstract

A device for locking the propeller of a UAV and its control method. A propeller locking early warning mechanism is established for the UAV autopilot, and a locking device is established at the rotating electric shaft of the propeller motor. The UAV braking control program established on the UAV autopilot, through the output of instructions to the servo controller, the air pressure valve is closed, and the air pressure brake block operates and controls the brake arm. The block brakes and locks the rotating electric shaft, and at the same time locks the propeller. The speed sensor can quickly judge the locked state of the propeller according to the speed signal from the rotating electric shaft, so as to realize the control of the UAV propeller in an emergency. Lock on to avoid drone accidents or oar injuries.

Description

technical field [0001] The invention relates to a device for locking the propeller of an unmanned aerial vehicle and a control method thereof, in particular to the technical field of locking the propeller of an unmanned aerial vehicle. Background technique [0002] At present, under the working conditions of high-speed rotation and vibration of existing drones, the propellers are easy to fall off, which is called propeller shooting in the industry, which is an important reason for drone flight accidents. Users are worried about the hidden dangers brought by drones, because if they are not controlled properly, they will not only crash easily, but also cause injuries or other accidents, especially the high-speed rotating blades. Once they hit people, they will be seriously injured. The aircraft model is very powerful. Although the aircraft model is not heavy, it is fast and flies over people's heads. However, due to the lack of safety guarantee for the assembled drone propelle...
