SAFETY GUARD DEVICE FOR UNMANNED AERIAL VEHICLE AND SAFETY GUARD METHOD FOR UNMANNED AERIAL VEHICLE

摘要

A safety guard device for an unmanned aerial vehicle and a safety guard method for an unmanned aerial vehicle. The safety guard device for an unmanned aerial vehicle comprises: an aircraft controller device (10), one or more motors and blade devices (20) connected to the aircraft controller device (10), one or more airbags (30) mounted inside a fuselage and a sensor., The sensor is used for sensing the speed of the unmanned aerial vehicle, and enables the one or more airbags to be deployed, upon sensing that the descending speed of the unmanned aerial vehicle is greater than a predetermined descending speed threshold or upon sensing that the descending acceleration of the unmanned aerial vehicle is greater than a predetermined descending acceleration threshold. The device and method can reduce the risk of an unmanned multi-rotor aircraft crash or device damage caused by collision with any person/object, reducing potential safety risks.
