Description

Technical Field

[0001] This utility model relates to the field of prefabricated drone cabinet technology, specifically to a multimodal transport drone cabinet system. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. UAVs can be categorized into military and civilian applications. In the civilian sector, the combination of drones with industry applications represents a genuine necessity. 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 drones. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] Logistics drones, with their advantages of high efficiency, convenience, and energy saving, are becoming a significant driving force in the logistics industry. Through technologies such as flight control systems, navigation and positioning systems, communication systems, and battery and energy management, logistics drones achieve precise transportation and real-time monitoring of goods. For example, agricultural drones have improved operational efficiency and reduced labor costs and environmental pollution in agriculture. In the construction industry, drone hoisting technology has also played a crucial role, enabling the rapid and safe delivery of building materials to designated locations.

[0004] The application of logistics drones in the civil aviation airport sector is gradually expanding. For the transportation of goods by small and medium-sized drones, matching drone warehouses are generally used. These warehouses not only help ensure the drones have sufficient charging and battery life but also enable them to perform their tasks. For example, utility model patent application number CN202410833822.1 relates to the field of drone delivery power storage technology. It describes a vertical power storage base station for a smart hospital unmanned delivery system, including a vertical storage cabinet with lateral electric control screws mounted on both sides inside. The cabinet also contains multiple bottom lifting plates controlled by these lateral electric control screws. While this vertical power storage base station includes charging and drone delivery functions, its functionality is limited and its structure is complex, making it unsuitable for transporting a significant amount of drone cargo. Utility model patent application number CN202322183463.3 discloses a cargo transportation system for logistics drones, which fixes a transfer box to a connecting plate, preventing the transfer box from separating from the drone during transport due to airflow or other environmental factors. However, its transfer boxes cannot form a systematic logistics transfer system. Utility Model Content

[0049] Example 1

[0050] Combination Figures 1 to 3 ,

[0051] Combination Figures 1 to 7 In the initial embodiment, the present invention proposes a multimodal transport drone cabinet system, including a box-type cabinet system, a drone control system, a logistics transportation system 2, a power distribution box and a system master controller. The box-type cabinet system includes an upper cabinet mechanism 3 and a lower cabinet mechanism 4, and the drone control system includes a drone lifting mechanism 1.

[0052] The upper cabinet mechanism 3 includes multiple first cabinet units 31. Each first cabinet unit 31 can be individually equipped with a drone controller 32, or multiple first cabinet units 31 can be equipped with one drone controller 32. The first cabinet unit 31 is equipped with a drone lifting mechanism 1, and the drone controller 32 controls the drone lifting mechanism 1 to work through the circuit.

[0053] The lower cabinet mechanism 4 includes a second cabinet unit 41 disposed above the first cabinet unit 31;

[0054] The logistics transportation system 2 includes an upper item transfer mechanism 21, an item picking mechanism 22, an inclined transfer mechanism 23, and a lower item transfer mechanism 24. A transfer channel is provided on the inner side wall of the adjacent first cabinet unit 31. The upper item transfer mechanism 21 is located in multiple first cabinet units 31 and is located inside the drone lifting mechanism 1. At this time, the upper item transfer mechanism 21 passes through the transfer channel and is located in multiple first cabinet units 31.

[0055] The item picking mechanism 22 picks up the items unloaded by the drone and places them on the upper item conveying mechanism 21; the upper item conveying mechanism 21 is connected to the tilting conveying mechanism 23, which is located between the upper cabinet mechanism 3 and the lower cabinet mechanism 4.

[0056] One end of the tilting conveyor 23 is connected to the upper item conveyor 21, and the other end is connected to the lower item conveyor 24 set in the lower cabinet mechanism 4. Storage mechanisms and item transport positions are respectively set in the lower cabinet mechanisms 4 on both sides of the lower item conveyor 24.

[0057] Example 2

[0058] There are multiple first cabinet units 31 and the number is even. The number of first cabinet units 31 can be 2, 4, 6, ..., increasing sequentially. The even number of first cabinet units 31 are divided into two groups, and the first cabinet units in each group are arranged vertically.

[0059] There are multiple second cabinet units 41, and the number is even. The multiple second cabinet units 41 are divided into two groups, and the second cabinet units 41 in each group are arranged vertically.

[0060] The first cabinet unit 31 and the second cabinet unit 41 are both rectangular cabinets in the style of shipping containers, but their overall structure is different from that of shipping containers. As needed, the storage mechanism can be designed in different categories. The storage mechanism includes a large storage platform, a medium-sized storage box and a small storage shelf. The transported items are placed in different types of storage mechanisms according to their different categories.

[0061] Example 3

[0062] In this embodiment, based on the size of the space, there are four first cabinet units 31 and four second cabinet units 41. A transition positioning frame 6 is set between the four first cabinet units 31 and the four second cabinet units 41. The transition positioning frame is for better hoisting and positioning. Although the traditional container-type cabinet is a finished product, it is generally welded for positioning after hoisting. By setting the transition positioning frame 6, the connection between the first cabinet unit 31, the second cabinet unit 41 and the transition positioning frame 6 can be a prefabricated connection. When hoisting the first cabinet unit 31, position sensors and hoisting markers can be set on the outside of the transition positioning frame 6 and on the first cabinet unit 31. The markers increase the clarity of visual observation during hoisting, and the position sensors can achieve precise positioning.

[0063] The transition positioning frame 6 includes a horizontal positioning frame 61, which comprises four cabinet limiting frames. Each cabinet limiting frame is assembled by welding four first angle steel plates and is rectangular in shape. The horizontal positioning frame 61 is placed on the second cabinet unit 41 and fixed with countersunk bolts. After fixing the countersunk bolts, sealant should be used to seal the location of the countersunk bolts to prevent water seepage. The first cabinet unit 31 is placed on the second cabinet unit 41 and the cabinet limiting frames and fixed with countersunk bolts. After the first cabinet unit 31 and the second cabinet unit 41 are connected by the transition positioning frame, theoretically, they cannot be easily moved unless subjected to a large typhoon or impact, relying on the weight of the cabinet unit itself. However, according to the customer's actual vibration resistance requirements, structural reinforcing vertical plates can be welded above and below the horizontal positioning frame 6. These reinforcing vertical plates are connected to the cabinet unit with countersunk bolts to increase structural strength. The number of reinforcing vertical plates is determined according to specific requirements, with each cabinet unit compatible with 3-8 reinforcing vertical plates.

[0064] Example 4

[0065] The first cabinet unit 31 includes a first cabinet frame 33 and a first cabinet wall panel assembly 34. The first cabinet wall panel assembly 34 is connected to the first cabinet frame 33 by first cabinet positioning bolts. The first cabinet frame is welded as a whole from 100*100 carbon steel square tubes.

[0066] A first UAV flight cavity 321 is provided on the first cabinet wall panel assembly 34 located on the top of the first cabinet frame 33. A first motor track module 322 is provided inside the first UAV flight cavity 321. A first top cover 323 is provided on the first slider inside the first motor track module 322. The first slider is driven by a first servo motor inside the first motor track module 322. After the first servo motor is driven, it drives the first slider to move, thereby causing the first top cover 323 to move. The control command of the first servo motor is sent through the wireless signal module of the UAV controller 32.

[0067] The second cabinet unit 41 includes a second cabinet frame and a second cabinet wall panel assembly. The second cabinet wall panel assembly is connected to the second cabinet frame by second cabinet positioning bolts. A conveying mechanism installation cavity is provided in both the first cabinet wall panel assembly located at the bottom of the first cabinet frame and the second cabinet wall panel assembly located at the top of the second cabinet frame.

[0068] The structure of the first cabinet frame 33 is similar to that of the second cabinet frame. The structure of the first cabinet wall panel assembly is similar to that of the second cabinet wall panel assembly. However, the first cabinet wall panel assembly 34 at the top of the first cabinet unit 31 needs to be separately equipped with a first top cover for drone flight and its supporting structure.

[0069] Example 5

[0070] The first cabinet wall panel assembly 34 includes a first cabinet narrow side wall panel 341 and a first cabinet long side wall panel 342. The narrowness and width of the first cabinet narrow side wall panel 341 and the first cabinet long side wall panel 342 are only relative comparisons and do not specify one as long or the other as short.

[0071] The first long wall panel 342 is installed in the front, rear, upper and lower faces of the first container frame 33. The positions in the front, rear, upper and lower faces refer to the longer side of the container unit, not a specific face. The first narrow wall panel 341 is installed in the left and right faces of the first container frame 33.

[0072] To improve the ease of installation of the narrow wall panel 341 and the long wall panel 342 of the first cabinet, we further refined the modular design of the narrow wall panel 341 and the long wall panel 342 of the first cabinet. The aim is to improve the convenience of installation, transportation, and subsequent maintenance of the entire cabinet unit.

[0073] The first cabinet's long wall panel 342 includes four long panel units, which are connected to the first cabinet frame 33 via a first long cross-shaped bracket 343. The first long cross-shaped bracket 343 not only positions the long panel units but also increases the overall structural stability. The first cabinet's narrow wall panel 341 includes four narrow panel units, which are connected to the first cabinet frame 33 via a first narrow cross-shaped bracket 344.

[0074] The first cabinet wall panel assembly 34 has a similar structure to the second cabinet wall panel assembly. The second cabinet wall panel assembly includes a narrow wall panel and a long wall panel.

The second cabinet's narrow wall panel includes four second cabinet narrow panel units, which are connected to the second cabinet frame via a second narrow cross-shaped bracket.

[0076] The edges of the first cabinet long panel unit, the first cabinet narrow panel unit, the second cabinet long panel unit, and the second cabinet narrow panel unit are all equipped with the first cabinet sealing strip.

[0077] The first cabinet long panel unit, the first cabinet narrow panel unit, the second cabinet long panel unit, and the second cabinet narrow panel unit are all composite insulated wall panels. Each composite insulated wall panel includes an outer steel plate. The inner surface of the outer steel plate is coated with an anti-rust and waterproof coating. Multiple structural reinforcing ribs are installed on the inner side of the outer steel plate. Approximately 50mm thick flame-retardant glass wool can be added to the inner side of the outer steel plate for insulation (used in areas with low temperatures). Aluminum foil stickers are adhered to the inner surface of the flame-retardant glass wool. Structural mounting plates are installed on the inner sides of the outer steel plate and the flame-retardant glass wool. These mounting plates serve as support plates for connecting electrical equipment within the cabinet unit, preventing direct drilling and connection of electrical equipment to the outer steel plate when connecting the cabinet unit.

[0078] Example 6

[0079] The drone lifting mechanism 1 includes a platform fixing frame 11 and a lifting platform 12. The bottom of the platform fixing frame 11 is equipped with a platform adjustment slide rail assembly, which is fixed on the bottom of the first cabinet unit 31.

[0080] The lifting platform 12 is mounted on the platform fixed frame 11. The lifting platform 12 includes four lifting screws 13 and four lifting guide rails 14 mounted on the platform fixed frame 11. The upper ends of the lifting guide rails 13 and 14 are provided with UAV platform plates 15. An AC motor drive system 16 is provided between the four lifting screws 13. The AC motor drive system 16 is connected to the lifting screws 13 through a transmission gear assembly. Platform plate limit sensors are provided on the lifting guide rails 13.

[0081] The lower end of the drone platform plate 15 is provided with a gravity sensing mechanism, and the upper end of the drone platform plate 15 is provided with an electric gripper assembly 17. The gravity sensing mechanism is connected to the drone controller through a line. A laser rangefinder is also provided in the positioning recess in the middle of the drone platform plate 15. The three sets of laser rangefinders are arranged in a triangle.

[0082] When the gravity sensing mechanism senses that the drone has landed on the drone platform, and all three sets of laser rangefinders detect that there is a drone above, the electric gripper assembly 17 is energized to grab the drone's legs 18. After the electric gripper assembly 17 grabs the drone's legs 18, it prevents the drone from shaking.

[0083] Example 7

[0084] The first cabinet unit where the drone lifting mechanism 1 is located is equipped with a drone placement mechanism 7. The drone placement mechanism 7 includes two U-shaped drone positioning frames 71. Each drone positioning frame 71 includes two first electric modules 72. A synchronous moving bracket 73 and a module positioning bracket 74 are arranged between the two first electric modules 72.

[0085] The module positioning bracket 74 is connected to the ends of the two first electric modules 72. The rear end of the module positioning bracket 74 is connected to the first swing arm through the first swing arm support. The rear end of the first swing arm is connected to the left or right inner wall of the first cabinet unit through the second swing arm support. The first swing arm generally does not move. When the module positioning bracket 74 is working, it will be placed on the lifting platform 12.

[0086] The end of the synchronous moving bracket 73 is connected to the moving block of the first electric module 72. A plastic steel plate is fixed to the inner end of the synchronous moving bracket 73, and a 5 mm thick rubber pad is set on the inner end of the plastic steel plate. When the drone flies to the top of the lifting platform 12, if the three sets of laser rangefinders do not detect the position, the moving block of the first electric module 72 drives the synchronous moving bracket 73 to move, pushing the drone to the position above the three sets of laser rangefinders. The position above the three sets of laser rangefinders is a region position, not a precise position accurate to the centimeter level. As long as it is in this position, the item picking mechanism can enter the working state. The item picking mechanism uses sensors such as video image sensors and gripper sensors to pick up the goods unloaded by the drone.

[0087] The electric gripper assembly 17 is located at the upper front and upper rear ends of the UAV platform plate. The electric gripper assembly 17 is located on both sides of the UAV placement mechanism 7. The electric gripper assembly 17 includes a gripper rotating support, a rotating hook 171 and a rotating motor mounted on the gripper rotating support. The rotating hook is in the shape of a long hook.

The item picking robot 221 is equipped with a wireless signal control module and is connected to a drone controller. One end of the robot base is connected to the inner wall of the first cabinet unit via a second telescopic hydraulic cylinder and rotating supports at both ends of the second telescopic hydraulic cylinder. The extension and retraction of the rod of the second telescopic hydraulic cylinder drives the robot base to move, thereby enabling the item picking robot 221 to move within a certain linear range.

The lower transport power controller is connected to the drone controller through a wireless signal sensing module. A conveyor belt moving roller assembly is provided at the lower end of the third linear conveyor belt.

[0094] The second cabinet unit on one side of the lower item transfer mechanism 24 has a transport vehicle entrance / exit, and a roller shutter door is installed on the transport vehicle entrance / exit;

[0095] The power distribution box is located in the second cabinet unit below the third linear conveyor belt. The system's main controller is connected to the power distribution box via lines, and the power distribution box is connected to the UAV control system and the logistics transportation system via lines.

[0096] Example 10

[0097] The specific installation details of the aforementioned multimodal transport unmanned aerial vehicle (UAV) cabinet system include the following:

[0098] Determine the number of the first and second cabinet units required in the multimodal transport unmanned aerial vehicle cabinet system, and complete the individual processing of the cabinet frame and cabinet wall panel components in the prefabrication plant according to the number of the first and second cabinet units.

[0099] A flight cavity is reserved for the first cabinet unit that needs to install the drone's top cover, and the first top cover and corresponding supporting structures are installed; after the cabinet frame and cabinet wall panel components are processed, they are transported to the target site by a transport vehicle.

[0100] Determine the target site. If the target site is outdoors, a concrete foundation needs to be poured and formed. The foundation should be poured according to the structural drawings and the load-bearing capacity should be greater than 800 kg / m². If the target site is indoors or on the roof, a steel structure should be used as the base foundation. The base foundation of the steel structure is a trapezoidal structure that is wider at the top and narrower at the bottom. A large shock-absorbing spring mechanism is also set at the bottom of the steel structure.

[0101] During installation, a crane is used to first hoist the cabinet frame of the second cabinet unit at the bottom. Then, according to space requirements, install the cabinet wall panel components within the second cabinet unit. The lower material handling mechanism and electrical distribution box are pre-placed within the second cabinet unit. The cabinet wall panel components at the top of the cabinet frame are not installed initially.
