Unmanned aerial vehicle provided with auxiliary lifting mechanism

Abstract

The invention relates to an unmanned aerial vehicle provided with an auxiliary lifting mechanism. The unmanned aerial vehicle provided with the auxiliary lifting mechanism comprises a fuselage, a load mechanism and a power mechanism, wherein the fuselage comprises a rack, a plurality of wing arms arranged on the rack, rotor wing devices arranged at the two ends of the wing arms and a control mechanism arranged on the rack, and each rotor wing device comprises a rotor wing motor and a propeller; and the unmanned aerial vehicle also comprises an auxiliary lifting mechanism which is connected and fixed on the fuselage, the auxiliary lifting mechanism can produce buoyancy force for floating upwards in air and is a bladder including gas inside, and the density of the gas inside the bladder is lower than the density of the air, and the buoyancy force of the auxiliary lifting mechanism is not more than the self gravity of the fuselage. The unmanned aerial vehicle provided by the invention has the advantages that the partial gravity of the fuselage is helped to be cancelled by virtue of the auxiliary lifting mechanism connected with the fuselage, so that the unmanned aerial vehicle is easier to take off and lift off and quickly enters a working condition, the energy consumption of a power mechanism is reduced, the cruising capability of the unmanned aerial vehicle is improved, the effective utilization rate of energy is increased, and energy conservation and environmental protection are realized.

Description

[0001] 【Technical field】 [0002] The invention relates to an unmanned aerial vehicle, in particular to an unmanned aerial vehicle with an auxiliary lifting mechanism. [0003] 【Background technique】 [0004] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Due to its low cost, good cost-effectiveness, good maneuverability, and convenient use, it is currently used in aerial photography, agriculture, plant protection, selfie, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, It is widely used in power inspection, disaster relief, film and television shooting and other fields. [0005] A UAV generally includes a body part, a control part, a power part and a load part; the body part is a frame, and a plurality of wing arms arranged on the frame; The rotor; the control part is the control mechanism arr...

AI Technical Summary

Problems solved by technology

It can be seen from the above that the overall weight of the UAV is relatively large. On the premise of not calculating the weight of the load part, the energy consumed by it to overcome its own gravity during flight is not small, which greatly reduces its endurance. Not conducive to the effective use of energy, not conducive to energy conservation and environmental protection
