Logistics unmanned aerial vehicle based on fixed wings

Abstract

The invention provides a logistics unmanned aerial vehicle based on fixed wings, and relates to the technical field of unmanned aerial vehicle logistics. The number of the fixed wings is four, the four fixed wings are installed on a machine body in an annular array shape, and a protective cover is connected to the bottoms of the fixed wings in a clamped mode. A bottom plate is mounted on the machine body, and two supporting seats are symmetrically mounted on the bottom plate. A set of clamping mechanism is installed between the two supporting seats, and a hook is installed on the clamping mechanism. Sliding seats are arranged on threaded rods, a touch switch is pressed to control a servo motor to rotate forwards, the servo motor rotates to drive the two sliding seats to move inwards at the same time, so that clamping plates clamp an object, through arrangement of the touch switch and the clamping plates, after the unmanned aerial vehicle descends, the clamping plates can move upwards under the influence of gravity, therefore, extrusion rods on the clamping plates extrude touch switches, the servo motors rotate reversely, the clamping plates move towards the outer side, conveyed objects automatically fall off between the clamping plates, and unloading of the objects is facilitated.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle logistics, and more specifically relates to a logistics unmanned aerial vehicle based on fixed wings. Background technique [0002] Unmanned aerial vehicle delivery is to carry parcels by unmanned low-altitude aircraft operated by radio remote control equipment and its own program control device, and automatically deliver them to the destination. Its advantages mainly lie in solving the distribution problems in remote areas and improving distribution efficiency. Reduce labor costs. The main disadvantage is that drones will be unable to deliver goods in bad weather. During the flight, man-made damage cannot be avoided. At present, SF Express already exists, but it has not been used on a large scale. Fixed-wing drones will be used in logistics transportation. UAVs are divided into large and small. Small fixed-wing UAVs are mostly multi-axis UAVs. Small fixed-wing UAVs are easy to op...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a logistics unmanned aerial vehicle based on a fixed wing, to solve the problem that the installation bracket at the bottom of the unmanned aerial vehicle can be adjusted poorly when the existing small fixed-wing unmanned aerial vehicle is transporting goods, and cannot Fast clamping of goods of different sizes. When the goods do not meet the best installation position of the mounting seat, the goods need to be bundled and transported. It is laborious to transport the goods. When the drone transports the goods, the goods need to be placed on the mounting bracket or fix the goods with hooks after binding them. The drone cannot realize the combination of the hook and the mounting bracket at the same time. The drone with the mounting bracket cannot quickly unload the goods when it reaches the transportation position, and the goods need to be manually unloaded. Unloading, which requires the controller to keep an eye on the unloading process of the drone, which is a troublesome problem during disassembly
