[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The embodiment of the present application discloses a server with an expandable hard disk module. Figure 1 and Figure 2 A server with an expandable hard disk module includes an expandable hard disk module, which is located directly above the original hard disk group. The original position of the expandable hard disk module is blocked by a front window hollowed out for heat dissipation. The expandable hardware module includes a hard disk backplane, a hard disk bracket 2 and a module cage 3 from the inside to the outside. The hard disk backplane is electrically connected to the hard disk, the hard disk bracket 2 supports the hard disk backplane and the hard disk, and the module cage 3 replaces the front window and is embedded and fixed above the original hard disk group. A plurality of slots are provided in the module cage 3, and a plurality of hard disk brackets 2 are respectively inserted into the slots of the module cage 3. This achieves the purpose of increasing the installation space for multiple expanded hard disks without changing the structure of the original server 1, thereby increasing the number of hard disks and effectively improving the storage capacity and flexibility of the server 1.

[0027] The hard drive backplane is made of high-quality aluminum alloy, designed with full compatibility with the server motherboard in mind. It integrates multiple standard interfaces, including SATA, SAS, and NVMe. These interfaces connect to the server motherboard via high-speed signal transmission lines, ensuring high data transmission speeds and stability. The backplane also features multiple pre-set hard drive interface slots, and connects to expansion hard drives via hard drive connectors.

[0028] Reference Figure 2 The main body of the hard disk bracket 2 is made of lightweight but high-strength aluminum alloy material through CNC precision processing. There are multiple hard disk brackets 2, and the hard disk brackets 2 are arranged in a multi-layer drawer layout. The hard disk backplane and hard disk are fixed in the hard disk bracket 2, and the hard disk bracket 2 itself is provided with a height adjustment mechanism 4.

[0029] Reference Figure 2 and Figure 3The hard disk bracket 2 is provided with a bracket arm 21 perpendicular to the hard disk insertion direction. There are two bracket arms 21 and they are distributed on both sides of the hard disk bracket 2. The bracket arm 21 is divided into sections along the vertical direction. The multiple sections of the bracket arm 21 are sequentially plugged in and slidably connected. The height of the bracket arm 21 can be freely adjusted according to the actual hard disk thickness, and the adaptability is strong. In this embodiment, two sections are taken as an example. The height adjustment mechanism 4 includes a limit screw 41. The limit screw 41 is arranged horizontally. One end of the limit screw 41 is passed through a section of the bracket arm 21 and is threadedly connected to the bracket arm 21. The rear end of the support arm 21 is pressed against the outer wall of the adjacent support arm 21, and the relative positions of the two adjacent sections of the support arm 21 are fixed by rotating the limit screw 41, so that the height of the support arm 21 can be quickly adjusted according to the actual size of the hard disk, which can meet the installation requirements of hard disks of different specifications; at the same time, elastic strips 6 are fixedly equipped at the top and bottom ends of the support arm 21 in the vertical direction, and the elastic strips 6 at both ends clamp the hard disk to ensure the stable installation of the hard disk. Even if the size of the hard disk is slightly smaller than the standard, it can be kept tight by the squeezing of the strips to reduce vibration.

[0030] Reference Figure 1 The modular cage 3 in this embodiment is a three-in-one module cage 3 that integrates hard drive interface conversion (e.g., SATA to PCIe), power distribution, and data transmission, greatly simplifying the hard drive access process. The modular cage 3 is designed as a plug-and-play device, docking with a dedicated port reserved on the rear of the server 1. It automatically identifies and configures hard drives, reducing the complexity and error risks of manual configuration, significantly simplifying hard drive management and maintenance, and lowering operating costs.

[0031] The module cage 3 is designed as an open frame structure with ventilation holes at the top, bottom, left and right sides to form a through-type air duct.

[0032] Reference Figure 1 and Figure 4 The outward-facing surface of the module cage 3 is flush with the outer shell of the server 1. Screws and angle plates can be used to secure the module cage 3 to the server 1. The module cage 3 is provided with multiple, neatly arranged mounting slots for inserting the hard drive tray 2. A slide rail mechanism 5 and a locking assembly are directly provided between the module cage 3 and the hard drive tray 2. The slide rail mechanism 5 includes a track 51 and a ball bearing 52. The track 51 is arranged horizontally along the direction in which the hard drive tray 2 is inserted into the module cage 3. There are two tracks 51, both fixed to the module cage 3. The ball bearings 52 are fixedly mounted at the four corners of the bottom of the hard drive tray 2. The four ball bearings 52 are divided into two groups and slideably connected to the two tracks 51. Pushing the hard drive tray 2 into the mounting slot of the module cage 3 causes the ball bearings 52 to slide along the track 51 after being inserted into it.

[0033] The latch assembly includes a spring-loaded locking pin 8 mounted on the module cage 3 and slidably connected thereto. A locking slot 9 is provided in conjunction with the locking pin 8 and is formed in the hard drive tray 2. When the hard drive tray 2 is slid into its installed position within the module cage 3, the locking slot 9 engages with the locking pin 8. To facilitate removal of the hard drive tray 2, the latch assembly also includes a release button to release the locking pin 8. Specifically, all locking pins 8 can be centrally controlled mechanically or hydraulically, or a controller system can be used to transmit a release signal using electrical components. The release button is located on the outer surface of the module cage 3 and controls the locking pins 8 on all hard drive trays 2. When the hard drive tray is properly inserted into the module cage 3, the locking pin 8 automatically drops into its pre-set locking position, emitting a distinct "click" sound, indicating that the hard drive is securely secured.

[0034] Reference Figure 3 The outer surface of the hard drive tray 2 is mounted with heat sinks 7, which are designed as thin, wavy or fin-shaped structures to increase surface area and promote air flow. Heat sinks 7 are fixedly connected to the outer surface of the hard drive tray 2. Since hard drives generate vibration and noise during high-speed operation, protective pads with integrated shock and noise reduction features are installed on the bottom and sides of the hard drive tray 2. These pads are inserted between the heat sinks 7, leaving them uncovered. This reduces the transmission of noise generated by the hard drives and improves the quietness of the server's operating environment.

[0035] The server with an expandable hard disk module in this application not only improves the hardware expansion capability of the server through the above mechanical structure setting, but also greatly optimizes the installation convenience, heat dissipation performance and noise control.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
