Description

Technical Field

[0001] The utility model relates to the technical field of suspended unmanned aerial vehicle cargo carrying, in particular to a suspended unmanned aerial vehicle cargo carrying device. Background Art

[0002] Unmanned aerial vehicle (UAV) is an unmanned aerial vehicle controlled by radio remote control equipment and self-contained program control devices. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. Compared with manned aircraft, it has the advantages of small size, low cost, easy use, low requirements for the combat environment, and strong battlefield survivability. In some special usage environments, drones are needed to transport goods, which can reduce the difficulty of cargo transportation.

[0003] Suspended UAV cargo carriers have emerged as the times require. By mounting a cargo basket that can carry cargo under the UAV, some cargo can be transported, which can reduce the difficulty of transportation. However, the cargo rack and the UAV need to be frequently disassembled to replace the UAV or the cargo rack. The cargo rack and the UAV are mostly connected by bolts, which makes disassembly inconvenient. Secondly, during the UAV's cargo transportation process, the UAV's fuselage will tilt slightly when flying, and there is a lack of a self-balancing device for the cargo rack between the cargo rack and the fuselage. Balance is particularly important when transporting some special items. Finally, there is a lack of sufficient shock-absorbing devices between the cargo rack and the fuselage. When the cargo rack contacts the cargo drop platform, a large impact force will be generated between the platform. Therefore, a suspended UAV cargo carrier is proposed to address the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A suspended unmanned aerial vehicle carrying device comprises a fuselage, a block and a carrying rack, wherein a fixed block is fixedly connected to the bottom end of the fuselage, a receiving groove is provided inside the fixed block, a first spring is fixedly connected inside the receiving groove, one end of the first spring is fixedly connected to a top rod, a clamping rod is fixedly connected to the bottom end of the block, a connecting rod is fixedly connected to the bottom end of the clamping rod, an arc plate is fixedly connected to the bottom end of the connecting rod, a cross shaft is rotatably connected to the inside of the arc plate, a sleeve is fixedly connected to the bottom end of the other connecting rod, a sliding plate is slidably connected to the inside of the sleeve, a connecting rod is fixedly connected to one side of the sliding plate, a second spring is provided on the outside of the connecting rod, a pull rod is fixedly connected to the bottom end of the connecting rod, and the bottom end of the pull rod is fixedly connected to the carrying rack.
