Multi-rotor unmanned aerial vehicle

Abstract

The invention relates to a multi-rotor unmanned aerial vehicle, which belongs to the technical field of unmanned aerial vehicles, and comprises a vehiclemachine body, a motor, rotors, a rotor protection frame and a foot stand, wherein the motor is arranged on the periphery of the vehiclemachine body; the rotors are arranged on a shaft of the motor; the rotor protection frame is arranged on the peripheries of the rotors; the foot stand is connected under the vehiclemachine body. In addition, a hanging rod is also arranged on the multi-rotor unmanned aerial vehicle, a hanging ring is arranged on one end of the hanging rod, and a magnet is arranged on the other end of the hanging rod. The hanging rod is hung on the machine body of the multi-rotor unmanned aerial vehicle through the hanging ring, and can rotate around the machine body. When the multi-rotor unmanned aerial vehicle is at a hovering condition, the hanging rod is hung under the machine body. The multi-rotor unmanned aerial vehicle provided by the invention can be hung an irony advertising board, a light pole, a traffic sign cross rod, an outdoor air conditioner, an iron stand, and iron tower and the like to work through a magnetic force of the magnet on the hanging rod, so that the work time of airborne equipment at a high place is greatly prolonged, and a posture and a position of the multi-rotor unmanned aerial vehicle are stable at a hanging state.

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
