Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an unmanned aerial vehicle (UAV) device that can be used to carry objects in the air. Background Art

[0002] With the rapid development of logistics and distribution systems, unmanned aerial vehicles (UAVs), as an innovative aerial transport tool, are playing an increasingly important role in connecting ground and air logistics networks. However, existing aerial cargo drones (UAVs) still face numerous challenges when performing high-altitude pickup missions. This paper reviews and analyzes existing technical literature to clarify the advantages and limitations of traditional rotary-wing UAVs, fixed-wing UAVs, and their hybrid designs, and to provide theoretical support and technical background for the design of novel UAVs.

[0003] 1. Traditional Rotary-Wing UAV

[0004] 1.1 Flexibility and controllability

[0005] Traditional rotary-wing drones are known for their vertical takeoff and landing capabilities and hovering capabilities, making them suitable for precise operations in complex environments. Their simple structure and mature control algorithms have made them widely used in short-range, high-precision missions[1]. However, these characteristics have brought new challenges to high-altitude pickup missions.

[0006] 1.2 Height Limit and Load Capacity

[0007] Because the cargo compartment is located below the fuselage, traditional rotary-wing drones must lower their altitude for high-altitude cargo transfers, increasing operational difficulty and risk. Furthermore, limited by battery energy density and rotor size, payloads are limited, making it difficult to meet the demands of transporting heavy materials.

[0008] 1.3 Stability and Security

[0009] Traditional rotary-wing drones lack stability and safety in windy conditions, especially between high-rise buildings or in complex environments. This limitation severely restricts their application in high-altitude operations.

[0010] 2. Fixed-wing drones

[0011] 2.1 Endurance and Speed ​​Advantages

[0012] Compared to rotary-wing drones, fixed-wing drones have longer flight times and a larger operating radius, making them suitable for large-scale area inspections or long-distance material transportation. Their high cruising speed allows them to cover a large area in a short period of time, which is particularly important in emergency material transportation.

[0013] 2.2 Harsh takeoff and landing conditions

[0014] While fixed-wing drones offer significant advantages in speed and endurance, they require challenging takeoff and landing conditions, requiring a runway or catapults, making them unsuitable for flexible deployment within cities or in complex terrain. Furthermore, the cargo compartment is typically located internally, hindering rapid loading and unloading, especially during high-altitude pickup missions.

[0015] 3. Specific issues regarding high-altitude catching tasks

[0016] In existing technologies, both traditional rotary-wing UAVs and fixed-wing UAVs have the following common problems when performing high-altitude pickup tasks:

[0017] Insufficient height adaptability: Unable to efficiently and safely complete cargo transfers at different heights.

[0018] Increased operational complexity: High-altitude operations require higher precision and stability, which traditional drones find difficult to meet.

[0019] Safety Challenge: Ensuring the safe flight of drones and the safe loading and unloading of cargo in complex environments, especially between high-rise buildings or in strong wind conditions, is a major challenge.

[0020] In summary, existing aerial cargo drone technology has significant limitations when performing high-altitude pickup tasks. Summary of the Invention

[0021] In response to the shortcomings of the prior art, the present invention aims to provide an unmanned aerial vehicle (AAV) device for aerial loading and unloading, enabling the AAV to autonomously determine and adapt to cargo docking requirements at varying heights, achieving precise and stable aerial loading and unloading capabilities. To achieve the above-mentioned objectives and other advantages of the present invention, an AAV device for aerial loading and unloading is provided, comprising:

This arrangement positions the cargo receiving assembly above the drone's base assembly, allowing the cargo platform to be positioned above the drone. Using a variety of sensors for environmental awareness, the drone can autonomously determine and adapt to cargo docking requirements at varying heights, achieving precise and stable aerial cargo delivery.

[0024] The drone base component is equipped with a GPS RTK module to improve the drone's positioning accuracy, and the drone base component is equipped with a Jetson Xavier NX module to provide computing power support for drone flight control.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1An unmanned aerial card device that can be used to carry objects in the air includes: a drone base assembly, the drone base assembly includes an upper splint 15, a lower splint 16 spaced apart from the upper splint 15, four transverse carbon square tubes 9 fixed between the upper splint 15 and the lower splint 16, and a flight assembly fixed to one end of each transverse carbon square tube 9 away from the upper splint 15; the upper splint 15 and the lower splint 16 are circular structures, and the four transverse carbon square tubes 9 are located between the upper splint 15 and the lower splint 16 and are radially distributed.

[0034] The object connection component is fixedly connected to the drone base component, and the object connection component includes an object connection frame 6, at least two longitudinal carbon square tubes 7 that are interference fit with the object connection frame 6, and one end of the longitudinal carbon square tube 7 away from the object connection frame 6 is fixedly connected to the transverse carbon square tube 9. The object connection component is located above the drone base component. The object connection frame 6 has a circular structure, and there are 4 card slots evenly distributed and fixed on the object connection frame 6. Each card slot passes through a longitudinal carbon square tube 7, and the card slots and the longitudinal carbon square tube 7 are rigidly fitted. A through hole is provided on the top of the longitudinal carbon square tube 7, and the through hole is located above the card slot. A bolt passes through the through hole. The object connection frame 6 is prevented from falling off the longitudinal carbon square tube 7 by the bolt, thereby limiting the movement of the object connection frame 6.

[0035] Furthermore, an adapter is fixed to one end of the transverse carbon square tube 9 away from the upper splint 15, and a longitudinal carbon square tube 7 is fixed to the adapter. The adapter includes a fixed block fixed to the transverse carbon square tube 9 and two parallel and spaced lateral carbon plates 8 fixed to the fixed block. The longitudinal carbon square tube 7 is inserted between the two lateral carbon plates 8, and the longitudinal carbon square tube 7 and the lateral carbon plates 8 are fixed by bolts, and the height of the longitudinal carbon square tube 7 in the vertical direction can be adjusted by bolts. Furthermore, by setting the four longitudinal carbon square tubes 7, a placement interval is set between the receiving frame 6 and the upper splint 15, and a woven net is installed on the receiving frame 6, and the receiving frame 6 receives objects through the woven net.

[0036] The installation process of the receiving frame 6 is as follows: insert the receiving frame 6 into the longitudinal carbon square tube 7 from the card slot in an interference fit manner. In order to ensure that the receiving frame 6 does not fall off during movement or impact, a hole is opened at the top of the longitudinal carbon square tube 7, and a bolt is screwed in. The bolt head is used to limit the movement of the receiving frame 6.

[0037] Further, such as Figure 2As shown, two spaced-apart, parallel support plates 10 are fixedly attached to one end of each transverse carbon square tube 9, distal from the upper clamping plate 15. Each support plate 10 comprises a straight section fixed to the side of the transverse carbon square tube 9 and a curved section integrally connected to the section. The straight section extends along the length of the transverse carbon square tube 9, and the curved section curves toward the ground from one end of the straight section near the curved section. In other words, four support plates 10 are provided in this application, and the drone is supported by these four support plates 10 when the drone is operating at zero power.

[0038] Further, such as Figure 3 As shown, a power supply frame is fixed to the bottom of the lower clamping plate 16. The power supply frame includes a left side plate 17 and a right side plate 18 fixed to the lower clamping plate 16. A power supply mounting base plate 5 is fixed between the left and right sides. The left and right sides plates 17, 18, and the power supply mounting base plate 5 form a power supply placement area. A GPS RTK module 4 is mounted on the side of the left side plate 17 to improve the positioning accuracy of the drone. An NX module 3 is mounted on the side of the right side plate 18 to provide computing power for drone flight control.

[0039] Further, such as Figure 1 As shown, the baffle 14 is fixedly connected to the upper clamping plate 15 , and the data transmission module 19 and the PX4 flight controller 20 are fixedly connected between the upper clamping plate 15 and the baffle 14 .

[0040] Further, such as Figure 4 As shown in the figure, when cargo is dropped onto and impacts the unmanned aerial vehicle (UAV), the vehicle rapidly collects data on its posture deviation using a multi-source sensor system. A data fusion system then integrates this measurement data and provides it to the intelligent decision-making system for accurate judgment. It then transmits commands to the position, speed, and posture controllers, enabling precise control of the motors. This ensures the UAV can stably and efficiently complete the automated docking process with the cargo.

[0041] To sum up, this application moves the cargo platform above the fuselage, combines advanced sensors and intelligent control systems, and uses multiple sensors for environmental perception, so that the unmanned aerial vehicle can independently judge and adapt to the cargo docking needs at different heights, and realize accurate and stable aerial pickup functions.

[0042] The number of devices and processing scales described herein are intended to simplify the description of the present invention, and applications, modifications, and variations of the present invention will be apparent to those skilled in the art.

[0043] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented without departing from the claims and the scope of equivalents.
