Adjustable multi-rotor-wing unmanned aerial vehicle

Abstract

The invention relates to an adjustable multi-rotor-wing unmanned aerial vehicle. The adjustable multi-rotor-wing unmanned aerial vehicle comprises a vehicle body, cantilevers, rotor-wing mechanisms and a bearing table. The bearing table surrounds the axis of the vehicle body and is evenly distributed on the outer side of the side surface of the vehicle body. Positioning sliding grooves are formed in the bearing table, and bearing sliding blocks are arranged on the bearing table. The tail ends of the cantilevers are hinged to the front end faces of the bearing sliding blocks through an adjusting mechanism. Each cantilever comprises a connecting section and at least two bearing sections, the tail end of each connecting section is connected with the bearing table, and the front end of each connecting section is connected with the corresponding bearing sections. The tail end of each bearing section is hinged to the corresponding connecting section through a ratchet wheel mechanism, the rotor-wing mechanisms are connected with the front end faces of the bearing sections of the cantilevers through sliding rails, and each rotor-wing mechanism comprises a bearing base, a driving mechanism and rotor wings. According to the adjustable multi-rotor-wing unmanned aerial vehicle, one the one hand, reliable and stable power output can be supplied to operation of the unmanned aerial vehicle; and on the other hand, the rotor-wing number and the rotor-wing distribution position during operation of the unmanned aerial vehicle can be flexibly adjusted, so that while operational stability and the bearing capacity of the unmanned aerial vehicle are effectively improved, the comprehensive utilization rate of power of the unmanned aerial vehicle is effectively improved, and energy consumption is reduced.

[0002] At present, multi-rotor drones have gradually become the main structural type of small drones due to their stable power output and strong carrying capacity. They have been widely used in aerial photography, geological surveys, and daily entertainment. With the in-depth application of multi-rotor UAVs, it is found in use that the rotor structure and number of current multi-rotor UAVs are fixed structures, so on the one hand, the current multi-rotor UAVs cannot operate according to the needs of use. , to flexibly adjust the body structure of the UAV, which limits the adaptability of the multi-rotor UAV to the use environment. Use the actual load conditions to flexibly adjust the power output of the UAV, especially when some multi-rotor UAVs with increased load capacity are operating under small or zero load conditions, due to the fixed number and position of the rotors, there is no When the man-machine is running, the actual power used by the rotor is relatively small when it consumes a lot of power, which causes serious energy waste and affects the endurance of the UAV, although currently such UAVs are often equipped with A special power adjustment control system is used to deal with the waste of energy consumption of UAVs, but the effect is minimal, and the number and position of UAVs due to the fixed number and position of rotors and other structures also increase the UAV's own energy consumption to a certain extent, thus It also further increases the energy waste of unmanned aerial vehicles. In view of this current situation, it is urgent to develop an inventive multi-rotor UAV structure to overcome the many deficiencies in the current multi-rotor UAV operation.
