Abstract

The invention relates to an obstacle detection device for an unmanned aerial vehicle (UAV). The obstacle detection device includes a body and a detection terminal. The side of the detection terminal is provided with an obstacle information acquisition module. The top of the detection terminal is provided with a hollowed connecting base. The lower end of the connecting base and the central portion at the top of the detection terminal are configured integrally. The upper end of the connecting base is provided with a second connection clamping groove. The body is provided internally with a control module and a drive motor. The control module is connected electrically with the information acquisition module and the drive motor separately. A mounting plate is disposed below the body. A first connection clamping groove is disposed below the mounting plate. A transmission shaft of the drive motor penetrates through the center of the mounting plate, and is located at the center portion of the first connection clamping groove. The first connection clamping groove matches the second connection clamping groove to configure the detection terminal as movable below the body. The device can prevent the UAV from colliding with an obstacle in the environment and avoid even large damage to a mechanical structure of the UAV that results in the loss of control and falling.

Description

technical field [0001] The invention belongs to the technical field of drones, and in particular relates to an obstacle detection device for drones. Background technique [0002] At present, the aircraft industry is in its infancy. With the maturity of UAV technology, its application in various industries is becoming more and more extensive. UAVs have been widely used in many fields such as aerial photography, rescue, forest fire prevention, and security. , which is mainly composed of a fuselage and multiple rotors. The operation process of a traditional aircraft is that the operator issues instructions to the flight control subsystem on the UAV through the controller, which sends the command to adjust the attitude to the motor regulator, and the motor regulator to To control the speed of the motor, the multi-rotor aircraft depends on the similarity and difference of the speed of the motors on each arm to change its flight attitude. There are no protective devices on the ro...
