Description

Technical Field

[0001] This utility model relates to the technical field of cargo box mechanisms, and in particular to a cargo box mechanism for unmanned aerial vehicles (UAVs). Background Technology

[0002] With the deep integration of drone technology and the logistics industry, drones, with their advantages of high flexibility, fast response speed, and no restriction by ground traffic, have been widely used in short-distance transportation scenarios for small items, such as last-mile delivery in cities and emergency supplies delivery. As the core load-bearing component of the drone transportation system, the performance of the cargo box directly determines the safety, reliability and efficiency of the transportation process. It not only needs to have sufficient structural strength to accommodate and protect the items to be transported, but also needs to achieve a stable connection with the drone and reliable closure of its own opening and closing structure to prevent the items from shifting, being damaged or even falling during flight due to vibration, turbulence or airflow interference.

[0003] Most existing cargo boxes use a single locking method to secure key components, such as mechanical buckles, single electronic locks, or simple bolt connections, to achieve the closure and fixation of the opening and closing parts to the box or the connection and fixation of the box to the drone mounting structure. This single locking design is prone to fatigue and loosening of the locking structure during drone flight, when faced with continuous vibration, airflow impact, or unexpected turbulence. This can lead to the opening and closing parts opening unexpectedly, the connection between the box and the drone becoming loose, and consequently, the displacement of items inside the box, collision damage, or even serious safety accidents such as items falling off, failing to provide stable safety assurance during transportation. To solve the above problems, this application proposes a drone cargo box mechanism. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drone cargo box mechanism. This drone cargo box mechanism, through its multi-locking, precise positioning, and convenient operation structural design, comprehensively solves the core problems of existing cargo boxes, such as unsafe locking, inaccurate positioning, and low operating efficiency. It significantly improves the safety, stability, and operational efficiency of drone transportation, and has strong practical value and promotion prospects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drone cargo box mechanism includes a box body, a limiting frame, two first locking mechanisms, and two second locking mechanisms. The top of the box body is rotatably connected to a flip-top cover via a hinge. A fixing plate is fixedly connected to the top of the flip-top cover, and two first U-shaped frames are fixedly connected to the top of the fixing plate. Each first locking mechanism includes a side plate fixedly connected to the side wall of the box body. A fixing block is fixedly connected to the top of the side plate, and a second U-shaped frame is fixedly connected to the top of the fixing block. An electronic lock is fixedly connected to the bottom of the limiting frame, and the second U-shaped frame and the electronic lock are locked together. Each second locking mechanism includes a connecting rod located on one side of the box body. A rotating rod is fixedly connected to the bottom of the connecting rod, and a top plate is fixedly connected to the top of the connecting rod. A reinforcing plate is fixedly connected to the bottom of the top plate. Two limiting mechanisms are provided on the limiting frame.

[0006] Preferably, the limiting mechanism includes a mounting plate fixedly connected to the side wall of the limiting frame, an electric telescopic rod fixedly connected to the top of the mounting plate, two mounting rings fixedly connected to the top of the limiting frame, and the output shaft of the electric telescopic rod passing through the two mounting rings and the first U-shaped frame.

[0007] Preferably, the bottom of the reinforcing plate has two limiting grooves, and the top of the limiting frame is fixedly connected to two limiting blocks, with the two limiting blocks respectively abutting against the inner wall of their corresponding limiting grooves.

[0008] Preferably, a limiting opening is provided through the limiting frame, and the first U-shaped frame is arranged through the limiting opening.

[0009] Preferably, the two electronic locks are located at both ends of the flip cover and arranged above the corresponding second U-shaped frame.

[0010] Preferably, a first through-hole is provided on the first U-shaped frame, a second through-hole is provided on the mounting ring, and the output shaft of the electric telescopic rod is arranged through the first and second through-holes.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The first locking mechanism, through the cooperation of an electronic lock and a second U-shaped frame, achieves initial stable fixation between the container and the limiting frame, providing the first layer of protection for their connection. The electric telescopic rod of the limiting mechanism passes through the mounting ring and the first U-shaped frame, forming a secondary locking of the flip cover and the limiting frame, further enhancing the reliability of the closure. In the second locking mechanism, the limiting groove of the reinforcing plate and the limiting block of the limiting frame fit together, not only improving the docking accuracy but also forming a third layer of structural constraint. The synergistic effect of multiple locking structures can resist vibrations, airflow impacts, and unexpected turbulence during drone flight, avoiding problems such as accidental opening of opening and closing parts and loosening of the container and mounting structure. This fundamentally eliminates the safety hazards of displacement, damage, or falling of items inside the container, significantly improving the level of transportation safety protection.

[0012] 2. The first U-shaped frame of the flip cover cooperates with the limiting port of the limiting frame to provide an initial positioning reference for the closing of the flip cover; the limiting groove of the reinforcing plate and the limiting block of the limiting frame adopt an interlocking design, which can realize the quick and accurate docking of the reinforcing plate and the limiting frame, while driving the first U-shaped frame to accurately pass through the limiting port; the mounting ring of the limiting mechanism plays a dual guiding role for the output shaft of the electric telescopic rod, ensuring that the output shaft accurately passes through the first U-shaped frame; multiple sets of positioning structures cooperate with each other, so that the workers can complete the locking operation without repeatedly adjusting the docking position, which greatly shortens the loading and installation time and improves the work efficiency.

[0013] In summary, this drone cargo box mechanism, through its multi-locking, precise positioning, and convenient operation design, comprehensively solves the core problems of existing cargo boxes, such as unsafe locking, inaccurate positioning, and low operational efficiency. It significantly improves the safety, stability, and operational efficiency of drone transportation, and has strong practical value and promising prospects for promotion. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-5A drone cargo box mechanism includes a box body 1 for accommodating the object to be transported, a limiting frame 13 for locking and limiting a flip cover 2, two first locking mechanisms and two second locking mechanisms. The top of the box body 1 is rotatably connected to a flip cover 2 that can be flipped around the hinge to open and close the box body 1, thereby facilitating the loading and protection of the object. The top of the flip cover 2 is fixedly connected to a fixing plate 3 that provides an installation base for a first U-shaped frame 4 and ensures a stable connection between the first U-shaped frame 4 and the flip cover 2. The top of the fixing plate 3 is fixedly connected to two first U-shaped frames 4 for cooperating with the electric telescopic rods 14 in the limiting mechanism to achieve precise positioning of the flip cover 2 and the limiting frame 13.

[0018] The first locking mechanism includes a side plate 5 fixedly connected to the side wall of the housing 1 to provide installation support for the fixing block 6, so that the fixing block 6 is stably arranged on the side wall of the housing 1. The top of the side plate 5 is fixedly connected to the fixing block 6 for connecting the side plate 5 and the second U-shaped frame 7 to achieve the height fixation of the second U-shaped frame 7. The top of the fixing block 6 is fixedly connected to the second U-shaped frame 7 for cooperating with the electronic lock 18. The locking of the two achieves the initial fixation of the housing 1 and the limiting frame 13. The bottom of the limiting frame 13 is fixedly connected to the electronic lock 18, which can form a locking engagement with the second U-shaped frame 7 to provide the first locking guarantee for the fixation of the housing 1 and the limiting frame 13 (the electronic lock 18 and the electric telescopic rod 14 communicate with the UAV flight control system through a wireless module, can be remotely controlled by a ground remote controller, and the UAV will automatically detect the locking status before takeoff. Takeoff is prohibited if it is not locked). The two electronic locks 18 are located at both ends of the flip cover 2 and are arranged above the corresponding second U-shaped frames 7. The second U-shaped frames 7 and the electronic locks 18 are locked together.

[0019] The second locking mechanism includes a connecting rod 9 located on one side of the housing 1, which connects the rotating rod 8 and the top plate 10 to form a linkage structure. The bottom of the connecting rod 9 is fixedly connected to the rotating rod 8, which serves as a rotation center, allowing the connecting rod 9, the top plate 10, and the reinforcing plate 11 to rotate and adjust their positions. The rotating rod 8 is fixed to the UAV fuselage support via bearing seats, which are secured with bolts. The top of the connecting rod 9 is fixedly connected to the top plate 10, which provides an installation carrier for the reinforcing plate 11 and ensures its stable arrangement. The bottom of the top plate 10 is fixedly connected to the top plate 10. A reinforcing plate 11 is fixedly connected to the limiting frame 13 by cooperating with the limiting block 17 through the limiting groove 12 at the bottom. The bottom of the reinforcing plate 11 has two limiting grooves 12 that fit into the limiting block 17 and provide a positioning reference for the docking of the reinforcing plate 11 and the limiting frame 13. The top of the limiting frame 13 is fixedly connected to two limiting blocks 17 that are embedded in the limiting grooves 12 to ensure accurate docking of the reinforcing plate 11 and the limiting frame 13. The two limiting blocks 17 are respectively arranged to abut against the inner wall of their corresponding limiting grooves 12.

[0020] The limiting frame 13 is equipped with two limiting mechanisms. Each limiting mechanism includes a mounting plate fixedly connected to the side wall of the limiting frame 13, providing mounting support for the electric telescopic rod 14 and ensuring its stability during operation. The top of the mounting plate is fixedly connected to a telescopic mounting ring 16 that passes through the output shaft and a first U-shaped frame 4, enabling a secondary locking of the flip cover 2 with the limiting frame 13. The limiting frame 13 has a through-hole 15 providing a through-channel for the first U-shaped frame 4, ensuring precise alignment between the first U-shaped frame 4 and the limiting frame 13. The first U-shaped frame 4 passes through the limiting hole 15. Two fixed connections at the top guide the output shaft of the electric telescopic rod 14, ensuring that the output shaft accurately passes through the mounting ring 16 of the first U-shaped frame 4. The output shaft of the electric telescopic rod 14 passes through the two mounting rings 16 and the first U-shaped frame 4 in sequence. The first U-shaped frame 4 has a through-hole to provide a through-hole for the output shaft of the electric telescopic rod 14, so that the output shaft can be accurately inserted into the first through-hole of the first U-shaped frame 4. The mounting ring 16 has a through-hole that cooperates with the output shaft of the electric telescopic rod 14 to further improve the guiding accuracy of the output shaft during extension and retraction. The output shaft of the electric telescopic rod 14 passes through the first through-hole and the second through-hole.

[0021] In this invention, the operator can open the flip cover 2 to load items into the box 1, and then close the flip cover 2 to the box 1 and place the device on the drone. The operator places the limiting frame 13 on top of the flip cover 2, and locks the second U-shaped frames 7 on both sides with two electronic locks 18 to complete the fixation of the box 1 and the limiting frame 13. Finally, the operator rotates the rotating rod 8, connecting rod 9, top plate 10, and reinforcing plate 11 (rotating with the rotating rod 8 as the rotation center) until the bottom of the reinforcing plate 11 covers the top of the limiting frame 13. At this time, the limiting block 17 is inserted into the limiting groove 12 to ensure the precise docking of the two, so that the first U-shaped frame 4 passes through the limiting opening 15. The electric telescopic rod 14 is activated to extend its output shaft until the output shaft of the electric telescopic rod 14 passes through the two mounting rings 16 and the first U-shaped frame 4, completing the locking and limiting of the flip cover 2 and the limiting frame 13. This device provides a simple dual protection solution.
