Abstract

The invention discloses an unmanned aerial vehicle for carrying expresses, and particularly relates to the technical field of unmanned aerial vehicle transportation. The unmanned aerial vehicle comprises lifting frames and a vehicle body, four corners of the bottom end of each lifting frame are fixedly connected with the corresponding lifting frames, moving trundles are arranged at the bottom ends of the lifting frames, the bottom end of the vehicle body is fixedly connected with a placing shell, and a connecting rod is fixedly connected to the outer part of the machine body. By arranging a supporting plate, a movable roller, a lifting hook, a servo motor, a rotating shaft, a supporting rod, a lifting rope and a winding roller, an express needing to be carried is hung in the lifting hook, when the express needs to be put down, the servo motor is started, the servo motor drives the winding roller to rotate through the rotating shaft, and the lifting rope can drive the lifting hook to descend through rotation of the winding roller; and the lifting hook descends to place an express at the bottom end of the lifting hook on the ground, the carrying speed can be increased by placing the express on the ground from the high position, the practicability of the device can be improved by arranging the lifting hook, and the movable roller can facilitate winding of the lifting rope through the winding roller.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle used for handling express delivery. Background technique [0002] At present, drones can be used in fields such as aerial photography, agriculture, plant protection, micro-selfie, express transportation, disaster relief, wildlife observation and film and television shooting. With the rise of online sales and e-commerce, online shopping has become more and more popular. The choice of express delivery is followed by the rapid development of the express delivery business. The delivery speed of express delivery seriously affects the development of express delivery companies. UAVs can not only deliver express delivery but also carry it quickly. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: [0004] (1) The traditional unmanne...
