Inflatable soft-body unmanned aerial vehicle

Abstract

The invention provides an inflatable soft-body unmanned aerial vehicle. The inflatable soft-body unmanned aerial vehicle comprises a power unit, an air bag, a gas valve and a carbon fiber framework. The outer surface of the carbon fiber framework is sleeved with the air bag. The gas valve is mounted on the air bag. The power unit is mounted on the carbon fiber framework. The power unit comprises a first power subunit, a second power subunit and a third power subunit which are distributed in a triangular manner. The first power subunit, the second power subunit and the third power subunit are the same in structure and each comprise a rotor, a brushless motor, a shell and a framework fixing device. Each shell is fixed to the corresponding carbon fiber framework through the corresponding framework fixing device. Each brushless motor is mounted in the corresponding shell. Each rotor is mounted on the corresponding brushless motor. Ventilation grids are arranged on the side wall of each shell at equal intervals. According to the inflatable soft-body unmanned aerial vehicle, precise cooperation between the air bag and the power unit can be used, the running time of the unmanned aerial vehicle is prolonged, and the free flight of the soft-body unmanned aerial vehicle is controlled conveniently.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an inflatable soft unmanned aerial vehicle. Background technique [0002] With the development of UAV technology, UAVs are more and more used in various industries. However, the traditional multi-rotor UAVs have short battery life and are easy to hurt people when they fall. They cannot meet the needs of large-scale outdoor activities or crowded activities. Man-machine use requirements, and balloons cannot meet the requirements of air mobility and autonomous cruise. [0003] Soft UAV is a UAV without a hard skeleton. It is formed by airbag inflation. Compared with traditional UAVs, it has a stronger load capacity and higher endurance. It can fly at ultra-low speed and ultra-low altitude. It has good elasticity and is resistant to impacts. It is not damaged and can be used for aerial photography, aerial survey, remote sensing and other purposes. [00...

AI Technical Summary

Problems solved by technology

[0004] Since the structure of the soft UAV is very different from that of the traditional UAV, its power setting is very different from that of the traditional UAV. The power supply devices such as rotors and coaxial propellers used by the traditional UAV cannot It is directly applied to soft drones. Because the soft drones are filled with gas, the existence of gas will affect the flight of soft drones. Therefore, the installation angle of the power unit of the soft drone and the cooperation between the power units are proposed. higher requirements, only when the power units cooperate properly can the free flight of the soft drone be realized
