Multi-rotor unmanned aerial vehicle

Abstract

The invention relates to a multi-rotor unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises an unmanned aerial vehicle body, motors, rotors, rotor protecting frames and foot frames, wherein the motors are mounted on the periphery of the unmanned aerial vehicle body; each rotor is mounted on a rotating shaft of the corresponding motor; each rotor protecting frame is arranged on the periphery of the corresponding rotor; the foot frames are connected to a position under the unmanned aerial vehicle body; in addition, a hanging rod is also arranged on the multi-rotor unmanned aerial vehicle; a hanging ring is arranged at one end of the hanging rod, and a hanging hook is arranged at the other end of the hanging rod; the hanging rod is hung on the unmanned aerial vehicle body of the multi-rotor unmanned aerial vehicle through the hanging ring, and can rotate around the unmanned aerial vehicle body; and when the multi-rotor unmanned aerial vehicle is under the hanging condition, the hanging rod is suspended under the unmanned aerial vehicle body. Through the hanging hook on the hanging rod, the multi-rotor unmanned aerial vehicle disclosed by the invention can be hung on objects at high positions including a wire, a branch, a road lamp cross bar, a billboard, a balcony railing, a high building rooftop enclosing wall and the like to work, so that the time for airborne equipment to work at the high position can be greatly prolonged, and under the hanging condition, the attitude and the position of the multi-rotor unmanned aerial vehicle are stable.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle. Background technique [0002] Multi-rotor drones usually have 3 to 8 rotors, especially 4 rotors are the most common. Multi-rotor drones have the functions of vertical take-off and landing, hovering in the air, low-speed flight, inverted flight, and side flight. Search, search and rescue, express delivery, etc. have been applied. Existing multi-rotor UAVs mainly have the following disadvantages: due to relying on the batteries loaded on the machine to provide electrical energy when hovering in the air, the battery life is short, and most multi-rotor UAVs that rely on battery power to work can only last one time. The flight time is about 10-30 minutes, that is to say, the working time of the multi-rotor UAV in the air is generally only 10-30 minutes, which is far from satisfying people's use of multi-rotor UAVs for long-ter...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a multi-rotor unmanned aerial vehicle that can stay on high objects for a long time to work or stand by, so as to solve the shortcomings of the existing multi-rotor unmanned aerial vehicles that have a short time to stay in the air and cannot work in the air for a long time
