Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) transportation technology, and in particular to a vehicle carriage structure for mounting UAVs. Background Technology

[0002] In recent years, with the rapid development of drone technology and the rise of the low-altitude economy, drone transportation has shown great potential in emergency material delivery, mountain and island transportation, and medical emergency response, thanks to its advantages such as flexibility, efficiency, and lack of ground traffic restrictions. Breakthroughs in heavy-duty drone technology, in particular, have made long-distance, high-load aerial transportation possible, providing a new solution for modern logistics systems. However, current drone transportation mainly focuses on bulk cargo handling, often limited to single, small-batch shipments. It cannot achieve rapid loading, transfer, and stacking of standardized cargo wagons, resulting in limited transportation efficiency and difficulty in meeting large-scale logistics demands. Especially in cargo / passenger scenarios, the lack of a direct docking system between drones and wagons severely restricts the coordination and flexibility of aerial transportation. Utility Model Content

[0003] The main purpose of this utility model is to provide a vehicle carriage structure for drone mounting, which aims to enable drones to directly mount and transport the carriage.

[0004] To achieve the above objectives, this utility model proposes a vehicle body structure for mounting unmanned aerial vehicles (UAVs), comprising:

[0005] The vehicle body includes a front end and a frame connected to the front end;

[0006] The carriage is placed on the frame. The carriage includes a top surface and multiple sides adjacent to the top surface. The sides are provided with mounting structures at the corners near the top surface. The mounting structures are used to connect with the drone.

[0007] In one possible implementation, a mounting element is connected to the top of the mounting structure, and the height of the mounting element does not exceed the top surface.

[0008] In one possible implementation, a suspension frame is also provided on the top of the carriage, the suspension frame is connected to the mounting member, and a connecting part is provided on the side of the suspension frame away from the top surface.

[0009] In one possible implementation, the suspension frame has two parallel connecting beams, the two ends of which are respectively connected to the mounting member, and multiple reinforcing beams are provided between the two connecting beams, with the connecting part disposed on the reinforcing beams.

[0010] In one possible implementation, the frame is provided with a limiting portion in the circumferential direction, which surrounds and limits the edge of the carriage.

[0011] In one possible implementation, the frame is further provided with a lifting structure that can lift the carriage upwards and disengage it from the limiting portion.

[0012] This utility model's technical solution utilizes a mounting structure located on the side of the carriage near the top corner. This structure not only meets the connection requirements of drones but also optimizes the layout to avoid affecting the vertical stacking of multiple carriages, significantly improving space utilization. The additional suspension frame on the top surface employs a combination design of double main beams and reinforcing beams, providing a stable connection point for high-load drones. The circumferential limiting part of the frame adopts a wrap-around structure, providing stable positioning and anti-displacement protection for the carriage, ensuring safety during transportation. The lifting structure equipped on the frame, driven hydraulically or electrically, can quickly lift the carriage away from the limiting part, greatly simplifying the loading and unloading process and allowing the carriage to freely switch between various modes such as drone lifting and forklift handling. The overall structure adopts a modular design, adapting to standard freight needs and quickly converting to a passenger-carrying configuration. Combined with the mounting components, it enables applications in multiple scenarios such as logistics transportation, emergency rescue, and military deployment. Attached Figure Description

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Reference Figures 1 to 3 This utility model proposes a vehicle body 3 structure for mounting drones, including a vehicle body and a vehicle body 3. The vehicle body includes a front end 1 and a frame 2 connected to the front end 1. The vehicle body 3 is placed on the frame 2. The vehicle body 3 includes a top surface 31 and multiple side surfaces 32 adjacent to the top surface 31. The side surfaces 32 are provided with mounting structures 4 at the corners near the top surface 31. The mounting structures 4 are used to connect with the drone.

[0022] Understandably, the vehicle body consists of a cab 1 and a frame 2, forming the basic framework of the vehicle. The cab 1 is used to provide power or control, while the frame 2 serves as a load-bearing structure, connecting the cab 1 and the cargo box 3. The cargo box 3 is an independent module placed on the frame 2, with a rectangular shape, including a top surface 31 and multiple sides 32, forming a closed or semi-closed space.

[0023] The mounting structure 4 can be a hook, connecting ring, or latch, etc., and is located on the side 32 near the corner of the top surface 31, i.e., the junction area between the side 32 and the top surface 31. The drone connects to the mounting structure 4 via ropes, robotic arms, or other devices to achieve aerial transport or movement. In this example, the mounting structure 4 is a connecting ring structure, which meets the requirements of quick assembly and disassembly, load-bearing capacity, and anti-swaying. The mounting structure 4 is located on the side 32, avoiding occupying the space on the top surface 31, and there is no interference between them, allowing multiple carriages 3 to be stacked vertically (such as saving ground space in logistics transportation). When empty carriages 3 are stacked, the bottom surface of the upper carriage 3 directly contacts the top surface 31 of the lower carriage 3 without additional adjustment; and the corner position can distribute the force on the drone during suspension, improving stability.

[0024] Furthermore, the vehicle compartment 3 can be designed as a cargo box with internal fixed supports or anti-slip layers to adapt to different cargo shapes. For example, during logistics transportation, drones can carry the cargo box to complete the "last mile" delivery, and the empty compartment can be folded, stacked, and recycled. It can also be modified into a passenger cabin, equipped with seats, safety facilities, etc., suitable for emergency rescue or special transportation scenarios. For example, during disaster relief, drones carrying passenger cabins can overcome terrain limitations and transfer trapped passengers. Through the above design, the vehicle compartment 3 achieves seamless integration with the drone system and efficient space management while maintaining functional versatility.

[0025] With the development of technology and the low-altitude economy, research and test flights of high-payload drones have also emerged. It should be noted that the mounting structure 4 can be connected to multiple drones or to a single high-payload drone.

[0026] Reference Figures 1 to 3 In one embodiment of this utility model, a mounting component 41 is connected to the top of the mounting structure 4, and the height of the mounting component 41 does not exceed the top surface 31.

[0027] Understandably, the mounting structure 4 is a connecting mechanism located at the corner of the side 32 of the carriage 3 near the top surface 31. It can be a metal bracket, a reinforcing interface, etc., used for docking with the drone. The mounting component 41 is a physical component on the mounting structure 4 that directly connects to the drone, such as a hook, a latch, a ball joint, etc., and is a key node for force transmission. The mounting component 41 is installed at the top of the mounting structure 4, that is, near the top surface 31 of the carriage 3. This has two advantages: firstly, it is mechanically reasonable, as being close to the top shortens the lever arm when the drone is suspended, reducing the swaying of the carriage 3 in the air; secondly, it is convenient to operate, as the high-positioned mounting component 41 is easier to grab or dock with when the drone approaches from above.

[0028] The highest point of the mounting piece 41 does not exceed the horizontal plane of the top surface 31 of the carriage 3. This means that the mounting piece 41 is completely embedded in the corner area of ​​the side 32, or adopts a flat design, such as a low U-shaped hook, a hidden slot, etc. In this example, the mounting piece 41 is a movable part with a rotatable hook, and its range of motion must also meet the height constraint when it is folded up.

[0029] The above settings ensure that the bottom of the upper carriage 3 is unobstructed when stacking. The protruding mounting part 41 will cause stacking gaps and make the stacking unstable. It also prevents the mounting part 41 from being bumped or damaged during transportation, as the protruding part is easily hit by other objects. It also reduces wind resistance during flight, as the protrusion may increase turbulence and affect stability.

[0030] Reference Figures 1 to 2 In one embodiment of this utility model, a suspension frame 5 is also provided on the top of the carriage 3. The suspension frame 5 is connected to the mounting member 41, and a connecting part 51 is provided on the side of the suspension frame 5 away from the top surface 31.

[0031] Understandably, the suspension frame 5 is located on the top surface 31 of the carriage 3, but it does not protrude directly. Instead, it is connected to the mounting component 41, forming a detachable structure. The suspension frame 5 has a connecting part 51 on the side away from the top surface 31, such as a hook, latch, or quick-release interface, for docking with high-load drones. Small and medium-sized drones are connected to the side mounting component 41 32, while high-load drones, such as heavy cargo drones, are connected to the suspension frame 5 on the top surface 31. Because of the better force distribution, the suspension frame 5 on the top surface 31 can provide more stable support for a single drone, reducing the torque on the side wall of the carriage 3; at the same time, it avoids swaying, and the high-position connection can reduce the risk of shaking during hoisting.

[0032] The suspension frame 5 and the mounting bracket 41 can be connected by a quick-release method. When it is necessary to stack the carriages 3, the suspension frame 5 can be removed without affecting the stacking. In this example, the suspension frame 5 is connected to the mounting bracket 41 by a hook. The connection part 51 should be as close as possible to the center of gravity of the carriage 3 to prevent tilting during hoisting.

[0033] This embodiment provides an additional stable connection point for a single high-load drone by setting up a suspension frame 5, which supports the mounting of ordinary drones and can also expand heavy transport capacity and improve system flexibility.

[0034] Reference Figures 1 to 2 In one embodiment of the present invention, the suspension frame 5 has two parallel connecting beams 52, the two ends of the two connecting beams 52 are respectively connected to the hanger 41, and multiple reinforcing beams 53 are arranged between the two connecting beams 52, with the connecting part 51 arranged on the reinforcing beams 53.

[0035] Understandably, the two connecting beams 52 are set in parallel to form the main frame of the suspension frame 5. Their two ends are fixed to the hanger 41 respectively to form a stable connection, which is used to provide the main load-bearing capacity and withstand the tension when the drone is hoisted. The parallel design can distribute the force and avoid single-point overload.

[0036] Multiple reinforcing beams 53 are horizontally arranged between the two main beams to form a structure similar to a "ladder" or "truss", which enhances rigidity and prevents the main beams from bending or deforming under stress; at the same time, it can distribute the load, making the overall stress of the suspension frame 5 more uniform and improving stability.

[0037] The connecting part 51, serving as the docking point for the UAV, is located on the reinforcing beam 53 in the central area of ​​the suspension frame 5. It can be a hook, latch, electromagnetic adsorption device, etc., used to connect with the UAV's sling or gripping mechanism. Multiple reinforcing beams 53 can provide multiple connection points, enabling multi-point fixation and adapting to the docking needs of different UAVs.

[0038] The suspension frame 5 in this example adopts a frame with double main beams and multiple reinforcing beams 53 to ensure stability and durability under high loads; the connecting part 51 is located on the reinforcing beams 53 to make the force more balanced and adaptable to different drones; it has high strength, resistance to deformation, and strong compatibility, and is suitable for heavy lifting scenarios such as logistics, rescue, and military.

[0039] Reference Figures 1 to 2 In one embodiment of this utility model, a limiting part 21 is provided around the frame 2, and the limiting part 21 surrounds and limits the edge of the carriage 3.

[0040] Understandably, the limiting part 21 is arranged around the frame 2, and can adopt a raised edge or an enclosing frame structure, with an L-shaped, U-shaped, or closed fence shape. Its inner edge contour matches the outer edge of the carriage 3, forming a close but not rigid contact wrapping relationship, maintaining an appropriate gap to accommodate thermal expansion and contraction and dynamic loads. The limiting part 21 restricts the lateral movement of the carriage 3, such as sideslip during turning, and the longitudinal displacement, such as the inertial forward lurch during sudden braking, by physically enclosing it, ensuring that the carriage 3 is stably placed on the frame 2; under bumpy or inclined road conditions, it prevents the carriage 3 from slipping off the frame 2 due to vibration or center of gravity shift, improving transportation safety. Furthermore, the limiting part 21 can be embedded with elastic materials such as rubber pads, which can absorb some impact energy and reduce the hard collision between the carriage 3 and the frame 2.

[0041] Reference Figure 2 In one embodiment of this utility model, the frame 2 is also provided with a lifting structure 22, which can lift the carriage 3 upward and disengage it from the limiting part 21.

[0042] Understandably, the power element of the lifting structure 22 can be a hydraulic cylinder, a pneumatic jack, or an electric screw lifting mechanism, respectively providing stable thrust, lightweighting, and precision control. The supporting component is a lifting arm or lifting plate, which is the load-bearing component that directly contacts the bottom of the carriage 3. In this example, it is a circular lifting plate, and it also has guide columns to ensure that vertical lifting does not deviate. By setting up the lifting structure 22 to assist in rapid loading and unloading, mechanical limit constraints are removed, making it easier for lifting equipment such as drones / forklifts to operate. After lifting the carriage 3, it is convenient to inspect the frame 2, facilitate the replacement of suspension components, and adapt to loading and unloading platforms of different heights.

[0043] This utility model's technical solution utilizes a mounting structure 4 located at the corner of the side 32 of the carriage 3 near the top 31. This structure not only meets the connection requirements of drones but also optimizes the layout to avoid affecting the vertical stacking of multiple carriages 3, significantly improving space utilization. The suspension frame 5 added to the top 31 adopts a combination design of double main beams and reinforcing beams 53, providing a stable connection point for high-load drones. The circumferential limiting part 21 of the frame 2 adopts a wrapping structure, providing stable positioning and anti-displacement protection for the carriage 3, ensuring safety during transportation. The lifting structure 22 equipped on the frame 2, driven hydraulically or electrically, can quickly lift the carriage 3 away from the limiting part 21, greatly simplifying the loading and unloading process and allowing the carriage 3 to freely switch between various modes such as drone lifting and forklift handling. The overall structure adopts a modular design, which can adapt to standard freight needs and can be quickly converted into a manned configuration. Combined with the mounting components, it can realize applications in multiple scenarios such as logistics transportation, emergency rescue, and military deployment.
