Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicles (UAVs), and more specifically, to a suspended UAV cargo carrier. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. Compared to manned aircraft, UAVs are often better suited for tasks that are too "dull, dirty, or dangerous." UAVs can be categorized into military and civilian applications. In the military field, UAVs are divided into reconnaissance aircraft and target drones. In the civilian field, there is a genuine demand for UAVs; their applications in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television production, and even creating romantic scenes have greatly expanded the uses of UAVs. Developed countries are also actively expanding industry applications and developing UAV technology.

[0003] Existing drone cargo-carrying devices (e.g., patent application number CN202020525372.7, which discloses a suspended drone cargo-carrying device) directly fix the cargo-carrying device to the drone wing. During use, the load is directly applied to the wing. However, due to the small size of drones, their wings are also small, and the wing's strength and load-bearing capacity are limited, which can easily lead to the wing breaking.

[0004] Therefore, the present invention urgently needs to solve the problem of providing a suspended UAV cargo carrier that can reduce the load on the wings, prevent the wings from breaking, and improve the load capacity of the UAV cargo carrier by using the combination of the suspension body and the cargo plate during use. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this invention is to overcome the problem in the prior art where the cargo carrier is directly fixed to the wing of the drone. During use, the load is directly applied to the wing, which, due to the small size of the drone and the limited strength and load capacity of its wings, is prone to breakage. Therefore, this invention provides a suspended drone cargo carrier that, through the combined use of a suspension body and a cargo plate, reduces the load force on the wing, prevents wing breakage, and improves the load capacity of the drone cargo carrier.

[0006] To achieve the above objectives, the present invention provides a suspended drone cargo carrier, which includes: a drone body, a suspension body, a cargo plate, and a fixing rod;

[0007] The top portion of the drone body is recessed inward to form a storage groove for accommodating the levitation body. A levitation body, which can float above the drone body after being filled with a certain amount of helium gas, is fixedly installed in the storage groove. At least two fixing rods are vertically and detachably mounted on both sides of the load-bearing plate. Each wing of the drone body has a vertical through hole that corresponds to all the fixing rods and allows them to pass through. The top of each fixing rod that passes through the through hole is fixed to the levitation body, so as to reduce the load on the drone body by the levitation body.

[0008] Preferably, a number of flexible resistance tubes are uniformly and vertically fixedly arranged on the suspension body.

[0009] Preferably, the hollow loading plate is provided with a stop to limit the load, the stop comprising: a stop rod, a spring, and a stop protrusion; wherein,

[0010] The upper surface of the loading plate has a number of guide holes that are evenly and vertically connected to its interior. Each guide hole has a stop bar that is vertically inserted through it. The top of the stop bar is fixedly provided with a stop protrusion, and the bottom of the stop bar is fixedly provided with a support block. Each stop bar located inside the loading plate is fitted with a spring. The two ends of each spring are fixedly provided on the loading plate and the support block, respectively.

[0011] Preferably, a vent pipe connected to the interior of the suspension body is fixedly installed on the suspension body, and a switch valve is fixedly installed on the vent pipe.

[0012] Preferably, the two sides of the loading plate are fixedly and horizontally spaced with assembly blocks that correspond to and are adapted to all the fixing rods. Each assembly block is assembled on the corresponding assembly block by a locking member. A first limiting member is fixedly provided on the assembly block located above the wing of the UAV body, and a second limiting member is threadedly connected to the fixing rod located below the wing of the UAV body.

[0013] Preferably, each of the fixing rods extends through the corresponding through hole to its lower part and is threadedly fixed with a locking element.

[0014] Preferably, the storage groove is also fixedly provided with an air pump for connecting the levitation body and filling its interior with helium gas, and the output end of the air pump is connected to the interior of the levitation body through a one-way air inlet pipe.

[0015] Preferably, the top opening of the storage recess is detachably provided with a sealing cap that can be closed at its opening.

[0016] According to the above technical solution, the beneficial effects of the suspended UAV cargo-carrying device provided by the present invention in use are as follows:

[0017] In use, the load is placed on the load plate, and then an appropriate amount of helium or air is filled into the suspension body to make it float in the air. During the take-off and flight of the drone, the buoyancy of the suspension body can reduce the pulling force of the load on the load plate on the drone, so that part of the load force acts on the suspension body and the other part acts on the drone body, thereby improving the drone's load-bearing capacity.

[0018] Compared to existing technologies, current drones are smaller in size, and the load is limited as it is entirely concentrated on the drone's wings. Furthermore, the load force of existing drone cargo carriers is entirely applied to the wings, which can easily cause wing breakage and reduce lifespan. This also limits the drone's load capacity. Therefore, the drone cargo carrier provided by this invention, under the buoyancy of the suspension body, can reduce the pulling force of the load on the drone, allowing part of the load force to act on the suspension body and the other part on the drone body, thereby improving the drone's load-bearing capacity and enabling it to carry heavier loads.

[0019] Therefore, by using the suspension body and the cargo plate in combination, the present invention can reduce the load force on the wings, prevent the wings from breaking, and improve the load capacity of the UAV cargo carrier.

[0020] Other features and advantages of the present invention will be described in detail in the following detailed description section; and all parts not covered in the present invention are the same as or can be implemented using the prior art. Attached Figure Description

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figure 1-6 As shown, the present invention provides a suspended drone cargo carrier device, which includes: a drone body 1, a suspension body 2, a cargo carrier plate 3, and a fixing rod 4;

[0032] The top portion of the drone body 1 is recessed inward to form a storage groove for accommodating the levitation body 2. The levitation body 2, which can float above the drone body 1 after being filled with a certain amount of helium, is fixedly installed in the storage groove. At least two fixing rods 4 are vertically and detachably mounted on both sides of the load-bearing plate 3. Each wing of the drone body 1 has a vertical through hole that corresponds to all the fixing rods 4 and allows them to pass through. The top of each fixing rod 4 that passes through the through hole is fixed to the levitation body 2, so as to reduce the load-bearing force of the load-bearing plate 3 and its load on the drone body 1 through the levitation body 2.

[0033] In the above scheme, during use, the load is placed on the load plate 3, and then an appropriate amount of helium or air is filled into the suspension body 2 so that the suspension body 2 floats in the air. During the take-off and flight of the drone body 1, the buoyancy of the suspension body 2 can reduce the pulling force of the load on the load plate 3 on the drone, so that part of the load force acts on the suspension body 2 and the other part acts on the drone body 1, thereby improving the drone's load-bearing capacity.

[0034] Compared to existing technologies, current drones are smaller in size, and the load is limited as it is entirely concentrated on the drone's wings. Furthermore, the load force of existing drone cargo carriers is entirely concentrated on the wings, which can easily cause wing breakage and reduce lifespan. This also limits the drone's load capacity. Therefore, the drone cargo carrier provided by this invention, under the buoyancy of the suspension body 2, can reduce the pulling force of the items loaded on the cargo plate 3 on the drone. This allows part of the load force to act on the suspension body 2, while the other part acts on the drone body 1, thereby improving the drone's load-bearing capacity and enabling it to carry heavier loads.

[0035] In a preferred embodiment of the present invention, a plurality of flexible resistance tubes 7 are uniformly and vertically fixedly disposed on the suspension body 2.

[0036] In the above scheme, during the descent of the drone body 1, air resistance is reduced by the air passing through several flexible resistance-reducing pipes 7 on the suspension body 2 and being discharged from their top ports. The resistance-reducing pipes 7 can be made of the same material as the suspension body 2, which can be made of flexible materials such as rubber or nylon used in parachute canopies.

[0037] In a preferred embodiment of the present invention, a stop member 5 for limiting the load is provided on the hollow loading plate 3. The stop member 5 includes: a stop rod 501, a spring 502, and a stop protrusion 503; wherein...

[0038] The upper surface of the loading plate 3 has a number of guide holes that are uniformly and vertically connected to its interior. Each guide hole has a stop rod 501 that is vertically inserted through it. A stop protrusion 503 is fixedly installed at the top of the stop rod 501 and a support block is fixedly installed at the bottom of the stop rod 501. A spring 502 is fitted on each stop rod 501 located in the loading plate 3. The two ends of each spring 502 are fixedly installed on the loading plate 3 and the support block, respectively.

[0039] In the above scheme, loads of different shapes can be placed directly on the carrying plate 3. Under the weight of the load, each stop protrusion 503 pressed by the load pushes the stop rod 501 downward in the vertical direction and stretches the spring 502 sleeved on the stop rod 501. This causes the load to descend under the action of the multiple stop rods 501 pressed down until the corresponding stop protrusion 503 abuts against the carrying plate 3. Meanwhile, the remaining stop rods 501 around the load that are not pressed by the load do not descend, thus stopping and limiting the load and preventing it from falling off the carrying plate 3 during transportation. Depending on the actual use, the length of the stop rod 15 can be appropriately increased so that after the load is placed on the carrying plate 3, the height of the other remaining stop rods 15 that are not pressed by the load is not lower than the height of the load.

[0040] In a preferred embodiment of the present invention, a vent pipe 6 communicating with the interior of the suspension body 2 is fixedly provided on the suspension body 2, and a switch valve is fixedly provided on the vent pipe 6.

[0041] In the above scheme, after the drone body 1 is used and lands on the ground, the load is removed from the load plate 3 and the switch valve can be opened to connect the vent pipe 6 with the external environment so that non-toxic helium or air can be discharged from the suspension body 2. After discharge, the suspension body 2 is folded and put into the storage groove.

[0042] In a preferred embodiment of the present invention, the two sides of the carrying plate 3 are fixedly and horizontally spaced with assembly blocks 11 that correspond to and are adapted to all the fixing rods 4. Each assembly block 11 is assembled on the corresponding assembly block 11 by a locking member 14. A first limiting member 12 is fixedly provided on the assembly block 11 located above the wing of the UAV body 1, and a second limiting member 13 is threadedly connected to the fixing rod 4 located below the wing of the UAV body 1.

[0043] In the above scheme, the first limiting member 12 and the second limiting member 13 are used together to fix the load plate 3 on the drone body 1 and limit its position.

[0044] In the above scheme, the opposing surfaces of the first limiting member 12 and the second limiting member 13 (that is, the surfaces that contact the wings of the drone body 1) are respectively fixedly provided with rubber pads, which are not shown in the attached figure. When the drone body 1 is on the ground, the wings of the drone body 1 are supported by the second limiting member 13. When the drone body 1 is in flight, the suspension body 2 pulls the cargo plate 3 up to the second limiting member 13, which abuts against the wings of the drone body 1 to limit the cargo plate 3.

[0045] In a preferred embodiment of the present invention, each of the fixing rods 4 extends through the corresponding through hole to its lower part and is threadedly fixed with a locking member 14.

[0046] In the above scheme, each of the fixed rods 4 is detachably mounted on the loading plate 3 by means of the locking member 14, thereby mounting the loading plate 3 on the drone body 1.

[0047] In a preferred embodiment of the present invention, an air pump 9 for connecting to the suspension body 2 and filling its interior with helium is also fixedly provided in the storage groove. The output end of the air pump 9 is connected to the interior of the suspension body 2 through a one-way air inlet pipe 10.

[0048] In the above scheme, the air pump 9 is connected to the helium tank, and the helium stored in the helium tank is injected into the suspension body 2 to make the suspension body 2 expand and float. Of course, the air pump 9 can also be directly activated to fill the suspension body 2 with external gas to make the suspension body 2 expand and float.

[0049] In a preferred embodiment of the invention, the top opening of the storage groove is detachably provided with a sealing cap 8 that can be closed at its opening.

[0050] In the above solution, after the suspending body 3 is degassed and folded into the storage groove, the sealing cover 8 can be placed over the storage groove to reduce the space occupied by the suspending body 3.

[0051] In summary, the suspended UAV cargo carrier provided by this invention overcomes the problem in the prior art where the cargo carrier is directly fixed to the UAV wing. During use, the load is directly applied to the wing, and because UAVs are small and their wings are also small, the wing strength and load capacity are limited, which can easily lead to the wing breaking.

[0052] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0054] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
