An obstacle warning device for drones

Abstract

The invention discloses an obstacle alarm device for unmanned aerial vehicles, which belongs to the technical field of unmanned aerial vehicles. An obstacle alarm device for unmanned aerial vehicles includes a body mechanism, and the body mechanism also includes a control body, and the top surface of the control body is The four corners are evenly provided with support arms, and the support arm is provided with an isolation mechanism for emergency protection on the bottom surface of the end far away from the control body, and the drive motor is fixedly installed on the top surface of the support arm far from the control body. The power output end of the motor is fixedly installed with a propeller, the center of the four sides of the control body is embedded with a ranging radar, and a storage slot is opened between the corner side of the control body and the bottom surface of the support arm; it can be realized in the UAV When an emergency hits an obstacle, it will perform emergency braking and activate the isolation mechanism for emergency avoidance to avoid the occurrence of a bombing. At the same time, the landing gear can be retracted after take-off, and the panoramic camera can be protected in an emergency.

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.
