Description

Technical Field

[0001] This invention relates to the field of large-scale drone transportation technology, and in particular to a large-scale drone transfer container. Background Technology

[0002] In current practices for transporting and transferring large drones, standard containers are commonly used in conjunction with simple lashing or bracket securing methods. While this approach has some versatility, it has revealed numerous shortcomings in practical applications.

[0003] First, due to the lack of a dedicated load-bearing and positioning structure, drones are extremely prone to displacement or even structural damage during transportation due to external forces such as bumps, vibrations, or sudden braking. This is especially true for fragile components such as wings, where traditional binding methods cannot provide sufficient support and protection.

[0004] Secondly, the loading and unloading process is highly dependent on external lifting equipment (such as cranes and forklifts) and a large number of manpower for coordinated operation, which not only results in low work efficiency but also poses high safety risks. Especially in field or in environments with weak infrastructure, external lifting resources are often difficult to arrive in time, which seriously restricts the rapid deployment capability of drones.

[0005] Furthermore, existing transfer devices typically lack sliding or transition structures, requiring drones to traverse elevation differences or be suspended in mid-air when moving containers from the ground. This necessitates complex operations and increases the risk of equipment collisions. More critically, most existing solutions fail to integrate transfer and lifting functions, separating loading / unloading from transportation. This prevents the realization of an integrated "loading-transportation-unloading-lifting" workflow, increasing equipment investment in intermediate stages and extending the overall operation cycle. Therefore, there is an urgent need for a dedicated transfer device with a rational structure, integrated functions, convenient operation, and a balance between transportation safety and operational efficiency to overcome the systemic deficiencies in the existing technologies.

[0012] The flip slide assembly is hinged to one end of the base; there are two sets of flip slide assemblies, and when the two sets of flip slide assemblies are opened, they are connected to the two sets of fixed slide assemblies; used to allow the two brackets to enter and exit the base.

[0013] The hoisting device is detachably connected to the bracket.

[0014] Preferably, the bracket includes:

[0015] The fixed frame is slidably connected to the corresponding fixed slide rail assembly;

[0016] The floating frame is positioned above the fixed frame.

[0017] The shock absorber is located between the fixed frame and the floating frame;

[0018] The conformal bracket is installed on the floating frame.

[0019] Preferably, both the fixed slide rail assembly and the tilting slide rail assembly are made of channel steel; and each of the four corners of the bottom of the fixed frame is equipped with a universal wheel that can be matched with the channel steel.

[0020] Preferably, the hoisting device includes:

[0021] The support frame, the bottom of which is detachably connected to the bracket;

[0022] The movable frame is horizontally slidably connected to the top of the support frame;

[0023] The guide wheel is rotatably connected to one end of the movable frame;

[0024] A winch is installed at the other end of the movable frame; the wire rope of the winch hangs down naturally after passing over the guide wheel, and a hook is installed at the end of the wire rope.

[0025] Preferably, the support frame has horizontal slide rails on both sides of its top, and the movable frame is slidably connected to the two horizontal slide rails on both sides; the horizontal slide rails include:

[0026] The fixing plate is securely connected to the support frame;

[0027] The rollers are arranged at intervals along the fixed plate, with adjacent rollers staggered vertically; the movable frame can pass between the upper and lower rollers.

[0028] Preferably, a reversing wheel is installed on the top of the movable frame, and the wire rope of the winch can be redirected through the reversing wheel; when the bracket enters the base, the movable frame is fixed on the base, and the bracket is pulled by the winch.

[0029] Preferably, one end of the bracket is hinged to a traction rod.

[0030] Preferably, the base is provided with a positioning seat for fixing the traction rod, and one end of the traction rod can be connected to the positioning seat through a pin.

[0031] Preferably, each of the four corners of the bracket is equipped with a hanging ring; a turnbuckle is installed on the base at the position corresponding to each of the four hanging rings; the turnbuckle can fix the bracket when connected to the hanging ring.

[0032] Preferably, one end of the base is equipped with three sealable packaging boxes, which are used to secure the engine, tail fin, and propeller, respectively.

[0033] By employing the technical solution described above, the present invention has the following beneficial effects:

[0034] (1) The base of this invention serves as the basic support platform for the entire transfer structure, ensuring that each functional component can be stably supported and providing a reliable fixing environment for the UAV. The brackets are set on both sides of the base and are used to fix the fuselage and wings of the UAV respectively, ensuring the stability of the main structure of the UAV during transfer. The fixed slide assembly allows the brackets to move along the slide direction, realizing convenient loading and unloading of UAV components and greatly simplifying the operation process. The hoisting device adopts a detachable connection method, which can directly hoist the UAV without relying on external equipment. This not only simplifies the assembly process and improves work efficiency, but also significantly reduces the physical burden on operators.

[0035] (2) This invention enhances stability and safety during transport by introducing a fixed frame and a floating frame design. The fixed frame serves as the lower support structure and is slidably connected to the corresponding fixed slide rail assembly; the floating frame directly supports the fuselage or wings of the UAV and is connected to the fixed frame through a shock absorber, effectively absorbing vibration and impact loads and protecting the UAV from damage. The conformal bracket is divided into two types according to the different components it supports: fuselage conformal bracket and wing conformal bracket. Its outline matches the local curved surface of the UAV, avoiding surface damage caused by local stress concentration. The design of the casters further enhances the flexibility of the bracket during on-site operations, while the tow bar enables rapid relocation within the site, improving transport efficiency.

[0036] (3) The present invention further specifies the design of the hoisting device, including components such as a support frame, a movable frame, guide wheels, and a winch. The bottom of the support frame and the bracket are detachably connected, which facilitates on-site installation and storage. The movable frame is slidably connected to the top of the support frame through a horizontal sliding structure. The wire rope released by the winch hangs down after passing over the guide wheels, and the end is connected to a hook for hoisting UAV parts. The winch is a manual-automatic integrated structure, which can be operated manually or driven by an external power source to adapt to the needs of different on-site conditions. In addition, the application of the redirecting wheel optimizes the force distribution of the hoisting device when hoisting the fuselage or wing. At the same time, the winch can also assist the bracket in automatic or semi-automatic return, reducing human intervention.

[0037] (4) The present invention further includes a positioning seat on the base for fixing the traction rod to prevent it from shaking and impacting the box or other components during transportation. The hanging rings installed at the four corners cooperate with the turnbuckles on the base to firmly lock the bracket by adjusting the tension, preventing it from shifting or shaking during transportation. In addition, three sealable packaging boxes are installed at the end of the base away from the flip slide assembly, which are used to store the key disassembly parts of the drone. The layout is reasonable, which facilitates quick access to or storage of relevant parts and improves the integration and practicality of the overall transfer system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] Example 1:

[0047] Combined with appendix Figures 1-3A large unmanned aerial vehicle (UAV) transport container includes a base 1, brackets 2, fixed slide rail assemblies 3, tilting slide rail assemblies 4, and a lifting device 5. The base 1 is fixedly installed at the bottom of the container, serving as the basic support platform for the entire transport structure, supporting and connecting the other functional components. Brackets 2 are respectively installed on the left and right sides of the base 1, supporting and securing the fuselage and wings of the UAV to ensure the stability of the UAV's main structure during transport. Fixed slide rail assemblies 3 are installed on the base 1 corresponding to the two brackets 2, each consisting of two parallel and spaced slide rails. The two brackets 2 are slidably connected to their corresponding fixed slide rail assemblies 3, allowing the brackets 2 to move back and forth between the inside and outside of the container along the slide rails, thus facilitating the loading and unloading of UAV components. Two sets of tilting slide assemblies 4 are hinged to one end of the base 1. When unfolded, these two sets of tilting slide assemblies 4 are aligned with and connected to two sets of fixed slide assemblies 3, forming a continuous sliding channel. This facilitates the smooth transition of the bracket 2 from the ground to the base 1, or its sliding out from the base 1 to the external working area. After the drone is loaded, the tilting slide assembly 4 can be flipped upwards and folded up to fit against the inner wall of the container end, thereby closing the container opening and facilitating subsequent transportation.

[0048] The lifting device 5 is detachably connected to the bracket 2. After the bracket 2 is detached from the base 1 and removed from the container, the lifting device 5 can be installed on the bracket 2. This device can be used to directly lift the fuselage or wings of the UAV without relying on external lifting vehicles or other auxiliary equipment, effectively simplifying the on-site assembly process, improving operational efficiency, and significantly reducing the physical burden on operators. Before container transfer, the lifting device 5 must be removed from the bracket 2 to avoid interference or collision with other structural components during transportation, ensuring the safety and reliability of the transfer process.

[0049] Example 2:

[0050] Combined with appendix Figures 1-3A large drone transport container is disclosed, further optimizing the structure of the bracket 2 based on Embodiment 1. The difference from Embodiment 1 lies in that the bracket 2 includes a fixed frame 2-1 and a floating frame 2-2. The fixed frame 2-1 is slidably connected to a corresponding fixed slide rail assembly 3, serving as the lower support structure of the bracket 2. The floating frame 2-2 is positioned above the fixed frame 2-1 to directly support the fuselage or wings of the drone. A vibration damper 2-3 is installed between the fixed frame 2-1 and the floating frame 2-2. This vibration damper 2-3 employs a wire rope vibration damper structure, effectively absorbing and isolating vibrations and impact loads from all directions during transport, thereby significantly improving the operational stability of the floating frame 2-2 during transport and protecting the drone structure from damage. A conformal bracket 2-4 is installed on the floating frame 2-2. The conformal bracket 2-4 is divided into two types according to the different components it supports: fuselage conformal bracket and wing conformal bracket. Its outer contour matches the local curved surface of the UAV fuselage or wing, which can fix the UAV while avoiding surface damage caused by local stress concentration, and achieve reliable clamping and protection of UAV components.

[0051] Furthermore, both the fixed slide assembly 3 and the tilting slide assembly 4 are constructed of channel steel, possessing high strength and rigidity, capable of bearing the weight of the bracket 2 and its load. At the four corners of the bottom of the fixed frame 2-1, casters 2-5 are installed. The wheel structure of these casters 2-5 is adapted to the cross-sectional shape of the channel steel slide, ensuring smooth operation of the bracket 2 on the slide. When the bracket 2 is completely detached from the base 1, it can move autonomously for short distances on the ground with the support of the casters 2-5, improving the flexibility of on-site operations. In addition, a traction rod 6 is hinged to one end of the bracket 2. This traction rod 6 can be connected to an external towing vehicle, using traction to quickly move the bracket 2 within the site, further improving transport efficiency.

[0052] Example 3:

[0053] Combined with appendix Figure 2 and 4A large unmanned aerial vehicle (UAV) transport container is disclosed, with a more detailed design of the lifting device 5 based on Embodiment 1 or Embodiment 2. The lifting device 5 includes a support frame 5-1, a movable frame 5-2, guide wheels 5-3, and a winch 5-4. The bottom of the support frame 5-1 is detachably connected to the bracket 2, specifically by bolts or by a connecting sleeve on the bracket 2, allowing for quick insertion and disassembly of the support frame 5-1 by inserting the bottom into the connecting sleeve, facilitating on-site installation and storage. The top of the support frame 5-1 has a horizontal sliding structure through which the movable frame 5-2 is slidably connected to the support frame 5-1. A guide wheel 5-3 is rotatably mounted at one end of the movable frame 5-2, and a winch 5-4 is fixedly mounted at the other end. The wire rope released by the winch 5-4 passes over the guide wheel 5-3 and hangs down naturally; a hook is connected to the end of the wire rope for attaching UAV components.

[0054] When hoisting the fuselage or wing, first install the support frame 5-1 onto the corresponding bracket 2, then assemble the movable frame 5-2 onto the top of the support frame 5-1. Lifting of the UAV component is achieved by operating the winch 5-4 to raise and lower the wire rope. After lifting, the movable frame 5-2 can be pulled horizontally along the top of the support frame 5-1 manually or with assistance, moving the lifted component laterally to accurately enter and exit the bearing area of ​​the bracket 2. The entire operation is simple and efficient. The winch 5-4 is a manual / automatic integrated structure, which can be operated manually or connected to an external power source, allowing for flexible selection of the operating mode according to site conditions.

[0055] Specifically, the support frame 5-1 has horizontal slide rails on both sides of its top, and the movable frame 5-2 slides in cooperation with these two horizontal slide rails on both sides. The horizontal slide rails consist of a fixed plate 5-5 and multiple rollers 5-6. The fixed plate 5-5 is firmly connected to the support frame 5-1 by fasteners. Multiple rollers 5-6 are installed at intervals along the length of the fixed plate 5-5. Adjacent rollers 5-6 are arranged vertically in a staggered manner, allowing the movable frame 5-2 to pass between the upper and lower rows of rollers 5-6 and slide smoothly between them, thereby driving the hoisted UAV components to move horizontally and complete the action of entering and exiting the bracket 2.

[0056] Furthermore, a deflector wheel 5-7 is installed on the top of the movable frame 5-2. After the wire rope of the winch 5-4 passes over the guide wheel 5-3, it can also be adjusted in direction via the deflector wheel 5-7, optimizing the force distribution of the entire lifting device 5 when lifting the fuselage or wing. In addition, when the bracket 2 needs to re-enter the base 1, the movable frame 5-2 can be removed from the support frame 5-1 and temporarily fixed to the base 1. At this time, the wire rope of the winch 5-4 is connected to the bracket 2, and the traction force of the winch 5-4 pulls the bracket 2 back to the base 1 along the slide, realizing automatic or semi-automatic return and reducing manual intervention.

[0057] Example 4:

[0058] Combined with appendix Figures 1-2 A large unmanned aerial vehicle (UAV) transport container, based on any one of the embodiments in Embodiments 1 to 3, further improves the fixing and auxiliary storage functions during the transport process. The base 1 is provided with a positioning seat 7 for fixing the towing rod 6. One end of the towing rod 6 can be connected to the positioning seat 7 through a pin. When the container is transported, the towing rod 6 is retracted and locked in the positioning seat 7 to prevent it from hitting the container or other components due to shaking during transportation, thus ensuring the safety of the overall structure.

[0059] In addition, hanging rings are installed at the four corners of the bracket 2; turnbuckles 8 are respectively installed on the base 1 at the positions corresponding to each hanging ring. After the bracket 2 slides into the base 1 and is in place, the turnbuckles 8 are connected to the corresponding hanging rings and tightened. By adjusting the tension of the turnbuckles 8, a preload can be applied to the bracket 2, thereby firmly locking it onto the base 1, effectively preventing the bracket 2 from shifting or shaking during transportation, and ensuring the stability and safety of the drone components during the transfer process.

[0060] Furthermore, three sealable packaging boxes 9 are installed at the end of the base 1 opposite to the tilting slide assembly 4. These three packaging boxes 9 are used to store key disassembled components of the drone, such as the engine, tail fin, and propeller. The installation positions of the packaging boxes 9 are rationally arranged to ensure that they do not interfere with the path of the bracket 2 as it moves in and out of the container along the slide, while facilitating the quick retrieval or storage of relevant components during loading and unloading operations, thus improving the integration and practicality of the overall transfer system.

[0061] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes falling within the meaning and scope of equivalents within this invention.
