Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] The following detailed description of a high-density battery integrated cabinet provided by this utility model, in conjunction with the accompanying drawings and embodiments, provides a specific example.

[0025] like Figures 1 to 5The diagram shows a high-density battery integrated cabinet, including a cabinet body 1 with multiple mounting cavities inside. Each mounting cavity is equipped with a slidably connected battery tray 2, and multiple signal connectors 6 are fixedly connected to the rear side wall of the mounting cavity. A quick-connect assembly 3 is fixedly connected to one side of the battery tray 2. The quick-connect assembly 3 includes an elastic buckle 7, a plug-in plate 14, positioning holes 15, and a compression spring 16. The plug-in plate 14 is fixedly connected to one side of the battery tray 2, and multiple positioning holes 15 are provided on one side of the plug-in plate 14. An elastic buckle 7 is embedded in the inner wall of the positioning hole 15. One end of the elastic buckle 7 slides in contact with the inclined surface of the locking block 8, and the other end is fixedly connected to the compression spring 16. The other end of the compression spring 16 is fixedly connected to the plug plate 14. When the battery tray 2 is inserted into the mounting cavity, the elastic buckle 7 slides along the inclined surface of the locking block 8 and is pressed into the positioning hole 15 until the elastic buckle 7 completely passes over the locking block 8. Then, the compression spring 16 pushes the elastic buckle 7 to reset and form a locking engagement with the locking block 8.

[0026] Multiple locking grooves 17 are provided on the side wall of the mounting cavity of the cabinet 1, and a rotating shaft 18 is fixedly connected to the inner side of the locking groove 17. A locking block 8 and a torsion spring 19 are sleeved on the rotating shaft 18. One end of the locking block 8 is rotatably connected to the locking groove 17 through the rotating shaft 18, and the other end has an inclined surface that contacts the protruding end of the elastic buckle 7. One end of the torsion spring 19 is fixedly connected to the locking block 8, and the other end is fixedly connected to the inner wall of the locking groove 17. When the elastic buckle 7 disengages from the locking block 8, the torsion spring 19 drives the locking block 8 to rotate around the rotating shaft 18 and return to its initial position.

[0027] Guide rails 4 are installed at both the top and bottom of cabinet 1, and a control box 5 is fixedly connected to the top. The guide rail 4 has a U-shaped cross-section and a ball bearing groove 20 on its inner side. Multiple balls 21 are embedded in the ball bearing groove 20, and these balls 21 form rolling contact with the outer edge of the battery tray 2. The outer side of the guide rail 4 is fixedly connected to cabinet 1 by bolts. The control box 5 is connected to a signal connector 6 inside the mounting cavity via wires. The signal connector 6 has multiple metal contacts, and the signal connector 6 is electrically connected to the battery module on the battery tray 2 through these metal contacts.

[0028] In addition, the top of the cabinet 1 is equipped with an exhaust vent, and a fan 10 is fixedly connected inside the exhaust vent. The fan 10 is movably connected to the control box 5 via a wire. The bottom of the cabinet 1 is equipped with an air inlet for air circulation and heat dissipation. The bottom of the battery tray 2 is fixedly connected with heat dissipation fins 9, which are in close contact with the bottom of the battery module. The surface of the heat dissipation fins is coated with thermal grease to enhance the heat conduction effect. Ventilation holes are also provided on the outer side of the heat dissipation fins 9 to further improve the heat dissipation performance.

[0029] On the front side of cabinet 1, an access door 11 is hinged and rotated. A sealing strip 22 is fixedly connected to the inside of the access door 11 to prevent dust and water. A handle 23 is fixedly connected to the outside for easy opening of the access door. Support legs 12 are fixedly connected to the bottom of the cabinet to stabilize the cabinet. Lifting rings 13 are fixedly connected to both sides of cabinet 1 by bolts for easy handling and installation.

[0030] To ensure the stable and reliable operation of the quick-plug assembly, the bevel angle of the locking block 8 is set between 30° and 45°, and the surface of the bevel is polished to reduce frictional resistance and improve the smoothness of plugging and unplugging.

[0031] Example 2

[0032] This embodiment further illustrates Example 1. When installing the battery tray 2, the operator pushes the battery tray 2 into the mounting cavity of the cabinet 1 along the guide rail 4. The design of the guide rail 4 ensures the linear sliding of the battery tray 2, with its internal ball bearings 21 making rolling contact with the outer edge of the battery tray 2, significantly reducing sliding resistance. When the battery tray 2 approaches the bottom of the mounting cavity, the elastic latch 7 on the quick-release assembly 3 begins to contact the locking block 8. The arc-shaped surface of the elastic latch 7 slides along the inclined surface of the locking block 8 and is pressed into the positioning hole 15 by the compression spring 16. As the battery tray 2 continues to advance, the elastic latch 7 completely passes the locking block 8 and resets under the push of the compression spring 16, its protrusion forming a locking engagement with the locking block 8, completing the installation of the battery tray 2. This design utilizes the automatic locking principle of a mechanical structure, achieving rapid and stable installation through the cooperation of the elastic latch 7 and the locking block 8, reducing the complexity of manual operation.

[0033] Secondly, during battery module operation, control box 5 collects battery status information in real time. Signal connector 6 is fixed to the rear wall of the mounting cavity, and its metal contacts connect to the corresponding electrodes of the battery module on battery tray 2, ensuring stable transmission of electrical signals. Control box 5 receives data from signal connector 6 via wires and monitors the voltage, current, and temperature of the battery module in real time. This data is transmitted to external devices through a communication interface for analysis and decision-making by maintenance personnel. This intelligent management method not only improves the system's response speed but also provides a reliable basis for fault diagnosis.

[0034] Subsequently, when the battery module's temperature rises due to prolonged operation, the cooling system comes into play. The heat sink fins 9 are in close contact with the bottom of the battery module and are coated with thermal grease to enhance heat conduction. Ventilation holes are located on the outer side of the heat sink fins 9, connecting to the air inlet at the bottom of the cabinet 1 to form an airflow channel. The fan 10 at the top of the cabinet 1 adjusts its speed according to the instructions of the control box 5, accelerating airflow and expelling heat from the exhaust vent. This design, combining air cooling and thermal conductivity, effectively reduces the operating temperature of the battery module and extends battery life. Furthermore, the fan 10's speed is dynamically adjusted by the control box 5 based on real-time temperature data, thus achieving a balance between energy saving and heat dissipation.

[0035] During maintenance, if a battery tray 2 needs to be replaced, the operator only needs to pull the plug plate 14, causing the elastic buckle 7 to slide along the inclined surface of the locking block 8 and disengage from the locking block 8. At this time, the locking block 8 automatically resets under the action of the torsion spring 19, and the battery tray 2 can be easily pulled out. The entire process requires no additional tools, significantly improving maintenance efficiency. Meanwhile, the design of the inspection door 11 facilitates the operator's opening of the cabinet 1 for internal inspection. The sealing strip 22 ensures the airtightness of the cabinet 1, preventing dust and moisture from entering and affecting equipment operation.

[0036] When moving the server rack, the lifting ring 13 provides a reliable lifting point, enhancing the convenience of rack handling.
