Description

Technical Field

[0001] This utility model relates to the field of cargo drone technology, and in particular to a long-endurance cargo drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio and their own programs. Due to their advantages such as small size and no human presence, they are widely used in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, and power line inspection.

[0003] With the economic development driving demand for freight transport and the practical application of green energy, electric drones are widely used in the freight sector. However, existing electric drones are limited by the low energy density of their batteries, resulting in small payload capacity, short flight time, and long charging times.

[0004] Chinese patent CN202323117640.4 proposes a method for connecting a cargo compartment drone via a retrieval mechanism, with the aim of achieving rapid door-to-door delivery. However, this design also reduces the safety of the drone. Utility Model Content

[0005] To address the aforementioned issues, the purpose of this invention is to provide a long-endurance cargo drone with strong scalability, large cargo capacity, and high safety redundancy.

[0006] The present invention is implemented using the following scheme: a long-endurance cargo drone includes a main platform, an endurance drone and a cargo box. Several docking joints for docking / separating the endurance drone are provided on the upper part of the main platform, and a central controller for scheduling the endurance drone is provided in the middle of the main platform. The cargo box is hung on the lower part of the main platform.

[0007] Preferably, the main platform is hexagonal, with six endurance drones, and several hoisting rings are equidistantly arranged along the hexagonal edge of the main platform.

[0008] Preferably, the main platform is also equipped with a battery that is electrically connected to the central controller.

[0009] Preferably, it also includes an extension platform composed of several extension spokes, wherein the connection points of the extension spokes are provided with docking / separation connectors for the extended-range UAV, the extension platform is connected to the side of the main platform, and multiple extension platforms are connected sequentially along the side of the main platform.

[0010] Preferably, an extension plate is also installed in the middle of the extension platform, and a counterweight is set in the middle of the extension plate.

[0011] Preferably, the connector includes a base and an electromagnet, with the base locked to the edge of the main platform and the electromagnet located on the top of the base.

[0012] Preferably, the electromagnet is an inverted cone shape, and a docking rod is provided at the bottom of the drone, with an inverted cone-shaped docking part hinged to the bottom of the docking rod.

[0013] Preferably, the five extended spokes are connected in sequence to form a hexagonal outer frame with a notch, and the hexagonal outer frame is connected to both ends of the side of the main platform along the notch.

[0014] The beneficial effects of this invention are as follows: Each drone in this invention carries its own battery power, and the central controller manages the propulsion vector for flight. As the battery power of a drone is consumed, it can detach and travel to a ground station to recharge, allowing other drones to take over the flight. Furthermore, the main platform can be extended along its outer edge to provide more connection points for the drones. The solution proposed in this invention offers strong capacity expansion capabilities, a large cargo capacity, and high safety redundancy during freight transport. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1 to 5A long-endurance cargo drone includes a main platform 1, an endurance drone 2, and a cargo box 3. The main platform 1 has several docking joints 11 on its upper part for docking / separating the endurance drone 2. The main platform 1 has a central controller 12 in the middle for scheduling the endurance drone 2. The cargo box 3 is hung on the lower part of the main platform 1.

[0023] This invention provides a novel design scheme, including a main platform 1 serving as the framework of a flight platform. Several endurance drones 2 can be detached / attached to the upper part of the main platform 1, while the lower part of the main platform 1 is used for securing / lifting cargo. Each endurance drone 2 carries its own battery power, and its propulsion vector is unified by a central controller 12. As the battery power of an endurance drone 2 is depleted, it can detach and travel to a ground station to recharge, allowing other endurance drones 2 to take over the flight. Furthermore, the main platform 1 can be extended along its outer edge to provide more connection points for the endurance drones 2. The solution proposed in this invention offers strong capacity expansion capabilities, a large cargo capacity, and high safety redundancy during freight transport.

[0024] The main platform 1 is hexagonal, with six endurance drones 2, and several hoisting rings 10 are equidistantly arranged along the edge of the hexagon on the main platform 1.

[0025] The main platform 1 is designed in a hexagonal shape to facilitate the expansion of more connection points for the extended-range drones 2. The hexagonal shape makes it easier to cover the entire plane and also facilitates the overall stress distribution of the main platform 1. Furthermore, the types of extended-range drones 2 can be varied. In general freight scenarios, multi-rotor drones are sufficient, while multi-ducted drones can be used to further improve safety and flight efficiency. Moreover, different types of drones can be combined and used in a unified manner.

[0026] The main platform 1 is also equipped with a battery 13 that is electrically connected to the central controller 12.

[0027] It also includes an extension platform 4 composed of several extension spokes 40. The connection points of the extension spokes 40 are provided with docking connectors 11 for docking / separating the drone 2. The extension platform 4 is connected to the side of the main platform 1, and multiple extension platforms 4 are connected sequentially along the side of the main platform 1.

[0028] An expansion plate 41 is also installed in the middle of the expansion platform 4, and a counterweight 42 is set in the middle of the expansion plate 41.

[0029] In this utility model, the extension spokes 40 serve as the frame of the extension platform 4. Several rings are equidistantly arranged on the extension spokes 40. These rings are used to further strengthen the stability between the extension spokes 40, and they can also serve as hanging points for the cargo box 3, making it convenient to hang larger cargo boxes 3.

[0030] The connector 11 includes a base 110 and an electromagnet 111. The base 110 is locked to the edge of the main platform 1, and the electromagnet 111 is located on the top of the base 110.

[0031] The electromagnet 111 is an inverted cone shape. The bottom of the drone 2 is provided with a docking rod 20, and an inverted cone-shaped docking part 21 is hinged to the bottom of the docking rod. The docking part 21 is attracted to the electromagnet 111.

[0032] In addition to being an inverted cone shape, the shape of the connector 11 proposed in this utility model can also be a connectable shape such as a toothed shape.

[0033] The five extension spokes 40 are connected in sequence to form a hexagonal outer frame with a notch, and the hexagonal outer frame is connected to both ends of the side of the main platform 1 along the notch.
