The invention relates to the technical field of logistics transportation. The invention discloses an unmanned aerial vehicle for logistics transportation. The unmanned aerial vehicle comprises an unmanned aerial vehicle body and a logistics box. The logistics box is fixedly connected to the lower portion of the unmanned aerial vehicle body. A negative pressure ring used for extracting air in an inner cavity of the logistics box is fixedly mounted at the top of the logistics box, a supporting plate is slidably connected into the inner cavity of the logistics box, a hollow pipe is fixedly connected to the bottom of the supporting plate, and a lifting mechanism used for increasing lifting force for the supporting plate is fixedly connected to the end, away from the supporting plate, of the hollow pipe. According to the invention, the lifting mechanism is connected to the lower of the supporting plate; air pressure difference of airflow on the upper surface and the lower surface of the lifting mechanism is utilized to form lifting force on the lifting mechanism; a force opposite to the gravity direction of the goods is applied to the supporting plate, the pressure of the goods and thesupporting plate on the bottom face of the logistics box is reduced, and therefore the tension of the gravity of the goods on the unmanned aerial vehicle is reduced, and the purpose of improving the weight of the goods borne by the unmanned aerial vehicle is achieved.
本发明涉及物流运输技术领域,且公开了一种物流运输用无人机,包括无人机主体和物流箱,所述物流箱固定连接在无人机主体的下方,所述物流箱的顶部固定安装有用于抽取物流箱内腔中空气的负压环,所述物流箱的内腔中滑动连接有托板,所述托板的底部固定连接有空心管,所述空心管远离托板的一端固定连接有用于给托板增加上升力的托升机构。本发明通过在托板的下方连接托升机构,利用气流在托升机构上下表面的气压差形成对托升机构的上升力,对托板施加一个与货物重力方向相反的力,降低了货物和托板对物流箱底面的压力,从而降低了货物的重力对无人机的拉力,因此达到提高无人机所能承载的货物重量的目的。
