UAV (Unmanned aerial vehicle) provided with falling guard device and falling guard method thereof

Abstract

The invention discloses an unmanned aerial vehicle provided with a falling guard device and a falling guard method thereof, belonging to the field of UAV (unmanned aerial vehicle). The UAV comprises a judgment module for judging whether the UAV is in a falling state or not, a controller for sending out ejection signals when judging that the UAV is in the falling state and an ejection mechanism for separating a part of the UAV from the UAV in an ejecting manner, wherein the controller is respectively connected with the judgment module and the ejection mechanism; the ejection mechanism is connected with the part separated in the ejecting manner. According to an idea that lighter parts and heavier parts in the aerial vehicle are separated automatically, the damage of the aerial vehicle in an airplane crash can be lowered, the safety of the aerial vehicle in the air is improved from another aspect, parachutes are installed on the heavier parts with regular shapes, the damage is further reduced, and the situation that the parachutes twine the heavier parts is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle provided with a fall protection device and a fall protection method thereof. Background technique [0002] At present, the multi-rotor UAV has been greatly developed, and it is favored by both the professional market and the consumer market. The reason why the multi-rotor unmanned aerial vehicle can be developed so rapidly is that the progress of related electronic technology has made the cost of this kind of aircraft rapidly reduced, and at the same time, the safety has been rapidly improved. [0003] However, as a device flying in the air, the multi-rotor unmanned aerial vehicle has endless requirements for flight safety. Users always hope that the aircraft will not crash due to any accident. But crashes are absolute, and what manufacturers and users can do is to reduce the probability of such crashes as much as possible. [0004] ...

AI Technical Summary

Problems solved by technology

[0009] However, the problem in the above scheme is that the structure of the multi-rotor unmanned aerial vehicle is relatively complicated. If a parachute is set on it, it will pop up in the event of a crash, and sometimes the effect of the parachute will not be very good due to the winding problem. Play; since the rotor-type unmanned aerial vehicle is often in a hovering state during the operation, at this time, there is no relative speed between the fuselage and the air. If a crash occurs at this time, the parachute cannot be automatically thrown or opened, and the fall cannot be reduced. speed, no protection against falling UAVs
