[0002] In the field of prefabricated modular container data centers, the main functions of container stacking include improving modular deployment efficiency, reducing construction costs, optimizing data center space layout, and ensuring structural safety and stability. Among these, improving modular deployment efficiency is one of the core values ​​of container stacking. Through vertical stacking and horizontal splicing, more IT equipment modules can be integrated within a limited land area, achieving exponential expansion of data center capacity. This efficient layout mode can greatly shorten the construction cycle.

[0003] Automation and stability of connections are particularly critical during stacking. In practical applications of stacked architectures, the performance and efficiency of the connection structure remain the core bottleneck restricting the technology's implementation. Current technological improvements often focus on a single dimension; for example, Schneider Electric's early solutions used reinforced welding to increase strength, but sacrificed assembly and disassembly flexibility. Therefore, a dynamically stable connection structure is urgently needed to overcome the barriers to the large-scale deployment of prefabricated modular containers. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-6 This invention describes the connection structure for container stacking.

[0027] like Figure 1 As shown, in an embodiment of this utility model, the container stacking connection structure includes: an upper corner piece 10, a lower corner piece 20, a connector 30, and a driving mechanism 40. The upper corner piece 10 is disposed on the top surface of the container 100, and has a first cavity 11. A first strip-shaped hole 12 is provided on the surface of the upper corner piece 10 facing away from the container 100. A locking head 31 is provided at the end of the connector 30, which is disposed within the first cavity 11, and extends beyond the upper corner piece 10. The lower corner piece 20 is disposed on the bottom surface of the container 100, and has a second cavity 21. A second strip-shaped hole 22 is provided on the surface of the lower corner piece 20 facing away from the container 100, and the extending direction of the second strip-shaped hole 22 is perpendicular to the extending direction of the first strip-shaped hole 12. The driving mechanism 40 is used to drive the connector 30 to rotate after it is inserted into the second cavity 21, so that the locking head 31 engages with the lower corner piece 20.

[0028] Specifically, in this embodiment, when two containers 100 are stacked, the locking head 31 of the connector 30 is embedded into the second cavity 21 of the upper container 100. At this time, the second strip hole 22 is perpendicular to the first strip hole 12, and the length direction of the locking head 31 is consistent with the length direction of the second strip hole 22. The driving mechanism 40 drives the connector 30 to rotate, so that the length direction of the locking head 31 is perpendicular to the length direction of the second strip hole 22, thereby locking the locking head 31 with the lower corner piece 20, thus connecting one corner of the two containers 100. Further, upper corner pieces 10 can be provided at the four corners of the top surface of each container 100, and each upper corner piece 10 corresponds to a connector 30 and a driving mechanism 40. Simultaneously, lower corner pieces 20 can be provided at the four corners of the bottom surface of each container 100, such as... Figure 6 As shown, when two containers 100 are stacked, they can be securely locked together by four connecting structures to prevent them from moving after being stacked.

[0029] Furthermore, when it is necessary to separate multiple stacked containers 100, the drive mechanism can drive the connector 30 to rotate in the opposite direction so that the length direction of the lock head 31 is consistent with the length direction of the second strip hole 22, thereby realizing the separation of two containers 100.

[0030] Optionally, in an embodiment of this utility model, the driving mechanism may include: a motor, a worm gear, and a worm. When the motor rotates, it drives the worm gear to rotate. The worm is connected to the connecting member 30, thereby driving the connecting member 30 to rotate. Optionally, the driving mechanism may also be a structure of a push rod, a rack, and a gear. The rack is disposed on the push rod, and the gear is sleeved on the connecting member 30. When the push rod moves, the rack drives the gear to rotate, thereby driving the connecting member 30 to rotate.

[0031] The container stacking connection structure provided in this embodiment of the utility model, by setting up upper corner pieces, lower corner pieces, a drive mechanism and connecting pieces, allows the drive mechanism to drive the lock head to rotate so that the lock head engages with the lower corner piece, thereby achieving stable stacking of the corresponding upper and lower corner pieces, improving the stability of ultra-high-rise container stacking, and realizing the integrity of container stacking. At the same time, when the drive mechanism drives the lock head to reverse, the lock head can be released from the lower corner piece, improving the convenience of container disassembly.

[0032] like Figure 2 As shown, in an embodiment of this utility model, the surface of the lock head 31 facing the lower corner piece 20 is rectangular, and the length of the rectangle is greater than the width of the second strip hole 22, so that it can engage with the lower corner piece 20 after the lock head 31 is rotated.

[0033] Specifically, in this embodiment, the length of the rectangle is less than the length of the second strip hole 22, and the width of the rectangle is equal to the width of the second strip hole 22. After the lock head 31 passes through the second strip hole 22 and is embedded in the second cavity 21, the drive mechanism 40 drives the connector 30 to rotate, so that the lock head 31 is perpendicular to the second strip hole 22, thereby engaging the lower corner piece 20. Furthermore, the lock head 31 is away from the surface of the lower corner piece 20, and its two ends form bevels to facilitate the lock head 31 passing through the second strip hole 22.

[0034] like Figure 3 As shown, in this embodiment of the present invention, the connector 30 further includes a rod 32 and an abutment shaft 33. The rod 32 is disposed within the first cavity 11 and connected to the drive mechanism 40. The two ends of the abutment shaft 33 are respectively connected to the rod 32 and the lock head 31. When two containers 100 are stacked, the abutment shaft 33 is located within the first slot 12 and the second slot 22. In this embodiment, the diameter of the abutment shaft 33 is equal to the width of the first slot 12 and the second slot 22.

[0035] Specifically, in this embodiment of the invention, the width and length of the first strip hole 12 and the second strip hole 22 are equal. The diameter of the abutment shaft 33 is equal to the width of the first strip hole 12 and the second strip hole 22, so that when the rod 32 rotates, the abutment shaft 33 can rotate within the first strip hole 12 and the second strip hole 22, thereby causing the lock head 31 to rotate. At the same time, the inner walls of the first strip hole 12 and the second strip hole 22 can act as a locking and limiting mechanism for the abutment shaft 33, ensuring that the edges of the two stacked containers 100 are aligned. This design not only improves the stability of the containers 100 when stacked, but also prevents the two containers 100 from shifting horizontally due to vibration during transportation.

[0036] like Figure 3 As shown in the embodiment of this utility model, the container stacking connection structure further includes a sleeve 61 and a positioning plate 62. Both the sleeve 61 and the positioning plate 62 are disposed within the upper corner member 10 for fixing the rod 32. The sleeve 61 is disposed on the bottom surface of the upper corner member 10, and the positioning plate 62 is disposed within the upper corner member 10 near the top surface. One end of the rod 32 is inserted into the sleeve 61, and the other end passes through the positioning plate 62. Under the action of the driving mechanism 40, the rod 32 can rotate relative to the sleeve 61 and the positioning plate 62.

[0037] Furthermore, in an embodiment of this utility model, the container stacking connection structure further includes a washer, which is sleeved on the outside of the abutment shaft 33 and located between the lock head 31 and the bottom surface of the lower corner piece 20. Optionally, the washer can be a rubber washer.

[0038] like Figure 4 As shown, in an embodiment of this utility model, the drive mechanism 40 includes: a driver 42, a drive assembly, a rack 45, and a gear 46. The drive assembly is connected to the driver 42 and is disposed within the upper corner piece 10. The drive assembly is equipped with a rack 45. The gear 46 is sleeved on the rod body 32 of the connecting piece 30, and the gear 46 is drively connected to the rack 45.

[0039] When the actuator 42 is activated, it drives the drive assembly to move linearly. When the rack 45 moves linearly, it causes the gear 46 to rotate, which in turn drives the connecting member 30 to rotate, so that the lock head 31 engages with the lower corner piece 20. Optionally, the actuator 42 can be an electric push rod or a linear motor.

[0040] like Figure 4 As shown, the drive assembly includes a push plate 43 and a guide rod 44. The push plate 43 is connected to the driver 42, the guide rod 44 is connected to the push plate 43, and a rack 45 is disposed on the side of the guide rod 44. When the driver 42 moves in a straight line, it drives the push plate 43 and the guide rod 44 to move in a straight line, and the rack 45 meshes with the gear 46, thereby causing the gear 46 to rotate.

[0041] Furthermore, such as Figure 4 As shown, in an embodiment of this utility model, the drive mechanism 40 further includes a battery 41, which is electrically connected to the driver 42 and is used to supply power to the driver 42.

[0042] like Figure 5 As shown in the embodiment of this utility model, the container stacking connection structure also includes a guide shaft 63. One end of the guide shaft 63 is connected to the inner wall of the upper corner piece 10, and the other end of the guide shaft 63 passes through the guide rod 44. When the guide rod 44 moves linearly, the guide shaft 63 guides the guide rod 44 to ensure that the rack 45 has high stability when moving horizontally.

[0043] When stacking two containers 100, the second container 100 is hoisted above the first container 100, aligning the lower corner piece 20 of the second container 100 with the connector 30 of the first container 100. The second container 100 is lowered so that the locking head 31 of the connector 30 passes through the second slot 22 into the second cavity 21. The control actuator 42 moves towards the connector 30, causing the guide rod 44 to move linearly, which in turn causes the gear 46 to rotate. When the gear 46 rotates, it causes the locking head 31 to rotate and engage with the lower corner piece 20. When it is necessary to separate the two containers 100, the control actuator 42 moves away from the connector 30. The actuator 42 causes the guide rod 44 to move backward, and the rack 45 causes the gear 46 to reverse, causing the locking head 31 to reverse, thereby releasing the locking head 31 from the lower corner piece 20.

[0044] In embodiments of this invention, the driver 42 can be remotely operated. Multiple drivers 42 on the same container 100 are controlled by the same remote control signal, making the operation more convenient and meeting the requirements for drive control in ultra-high-rise stacking. The driver 42 can also be wirelessly controlled via WiFi. Users only need to deploy WiFi coverage in the area of ​​use and plan the IP addresses of each module. The module can be remotely controlled via the Internet cloud. Multiple drivers 42 on the same container 100 together constitute the same module, which can realize the automated stacking control of the container 100. At the same time, its automated drive operation makes its actual use more convenient and avoids the situation where the container 100 is not stacked tightly. Compared with manual operation, it avoids the situation where some corners are blocked by other containers 100 and cannot be operated.

[0045] like Figure 1 As shown in the embodiment of this utility model, the container stacking connection structure also includes a box body 50, which is connected to the upper corner piece 10. The battery 41 and the driver 42 are both disposed inside the box body 50.

[0046] The container stacking connection structure provided in this embodiment of the utility model can automatically drive the connector to engage or disengage with the lower corner piece, enabling remote operation and control when stacking containers. Compared with traditional manual operation and control, it is more convenient to operate and improves operational safety, eliminating the need for manual climbing.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
