Obstacle alarm device for unmanned aerial vehicle

Abstract

The invention discloses an obstacle alarm device for an unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles, the obstacle alarm device for the unmanned aerial vehicle comprises a machine body mechanism, the machine body mechanism further comprises a control machine body, and supporting arms are uniformly arranged at four corners of the top surface of the control machine body; an isolation mechanism used for emergency protection is arranged on the bottom face of the end, away from the control machine body, of the supporting arm, a driving motor is fixedly installed on the top face of the end, away from the control machine body, of the supporting arm, a propeller is fixedly installed at the power output end of the driving motor, and ranging radars are embedded into the centers of the four side faces of the control machine body. A storage groove is formed between the side face of the corner of the control machine body and the bottom face of the supporting arm. According to the unmanned aerial vehicle, when the unmanned aerial vehicle collides with a barrier emergently, emergency braking can be conducted, the isolation mechanism is started to avoid danger emergently, the situation that the unmanned aerial vehicle is exploded is avoided, and meanwhile the takeoff and landing support can be folded after takeoff and protect the panoramic camera in an emergency state.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, and more specifically, relates to an obstacle warning device for unmanned aerial vehicles. Background technique [0002] UAVs are often more suitable for performing tasks in some harsh environments. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, it is the real rigid demand of drones; currently, it is used in aerial photography, agriculture, plant protection, micro selfie, express transportation, disaster rescue, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting, Applications in the field of manufacturing romance have greatly expanded the use of drones themselves. Developed countries are also actively expanding t...

Problems solved by technology

[0004] When the UAV encounters obstacles such as tree branches in an emergency, when the operator cannot react, it can only drive towards the obstacle passively, and cannot avoid danger in an emergency;

[0005] The existing UAV landing brackets basically cannot be retracted, and can only be hung on the bottom of the body. It is easy to touch obstacles during the flight of the UAV, which will hinder the flight of the UAV.
