Eight-rotor type unmanned aerial vehicle for logistics transportation
ActiveCN111806694AIncrease transport distanceImprove transportation efficiencyFreight handlingRotocraftLogistics managementUncrewed vehicle
The invention relates to the field of logistics transportation equipment, and discloses an eight-rotor type unmanned aerial vehicle for logistics transportation, the eight-rotor type unmanned aerial vehicle comprises a vehicle body, eight rotor cross shafts which are symmetrically distributed are arranged in the outer side of the vehicle body, a rotor mechanism is arranged at the farthest end of each rotor cross shaft, and positioning rods are fixedly connected to the middles of the two symmetrical rotor cross shafts on the vehicle body. The eight-rotor type unmanned aerial vehicle for logistics transportation is provided; an upper wing plate and a lower wing plate which can rotate at the same time are arranged at the top and the bottom of the logistics box. When the rotor wing unmanned aerial vehicle flies forwards, airflow acting in the reverse direction acts on the upper wing plate, the logistics box and the lower wing plate; according to the rotor wing unmanned aerial vehicle, theupper wing plate and the lower wing plate are arranged, so that airflow passing through the upper wing plate and airflow passing through the lower wing plate form up-down pressure difference, upward buoyancy is provided for the whole logistics box, the farthest transportation distance of the rotor wing unmanned aerial vehicle is increased, heavier expresses can be conveniently transported at a time, the express transportation efficiency is improved, and energy consumption of the unmanned aerial vehicle is reduced.
