Description

Technical Field

[0001] This utility model relates to the field of computer equipment technology, and in particular to a modular, easily replaceable hard drive tray. Background Technology

[0002] With the rapid development of information technology, computer hard drives, as the core component for data storage, undertake crucial functions such as operating system operation, user file storage, and application access. Traditional mechanical hard drives (HDDs) rely on the physical read / write mechanism of the disk and read / write heads, while solid-state drives (SSDs), thanks to the non-volatile storage technology of flash memory chips, have achieved significant improvements in speed, shock resistance, and energy consumption. Currently, mainstream hard drive interfaces include SATA, M.2 (NVMe protocol), and PCIe, with transfer rates ranging from hundreds of MB / s to several GB / s, fully meeting users' needs for high-performance storage.

[0003] However, existing hard drive expansion solutions for home computers still have significant drawbacks:

[0004] 1. Limited number of motherboard interfaces: Home motherboards typically only provide 1-2 hard drive slots, which is insufficient to meet users' needs for multiple hard drive expansion (such as running multiple systems in parallel, backing up large amounts of data, or storing multimedia libraries).

[0005] 2. The disassembly and assembly process is cumbersome and risky: Users need to frequently remove the side panel of the chassis, and even remove the motherboard mounting screws to connect a new hard drive. This process can easily lead to loose cables, electrostatic damage, or physical deformation of the motherboard, making it extremely unfriendly to non-professional users.

[0006] 3. Hardware compatibility limitations: Traditional hard drive brackets mostly use a fixed design, which cannot be adapted to different sizes (such as 2.5-inch SSDs and 3.5-inch HDDs) or interface types (such as SATA and M.2), further increasing the complexity of expansion.

[0007] Taking a typical application scenario as an example, if home users need to upgrade storage capacity or replace a faulty hard drive, they often need to shut down the computer, completely disconnect the power, and disassemble the chassis before connecting the new hard drive through complex wiring. This process is time-consuming and labor-intensive, and poses a high barrier to entry for users with insufficient hardware operation experience. Although external hard drive enclosures can provide temporary expansion solutions, the number of hard drives they can connect is very limited and cannot be increased or decreased according to actual needs. Therefore, there is an urgent need for a modular hard drive expansion solution that does not require disassembling the chassis and supports hot-swapping of multiple interfaces to solve the core contradiction of limited interface resources and low maintenance efficiency in existing technologies. Utility Model Content

[0009] A modular hard drive bay, wherein the modular hard drive bay is provided with multiple pull-out hard drive mounting components;

[0010] A modular bracket chassis is provided, wherein the modular hard drive bay is fixedly connected to the modular bracket chassis, and the modular bracket chassis is provided with multiple sub-hard drive interfaces corresponding to the hard drive mounting components. Each sub-hard drive interface is electrically connected to the main interface of the modular bracket chassis, and the main interface is electrically connected to the hard drive interface of the motherboard through an extension cable.

[0011] Preferably, the modular hard disk drive bay includes:

[0012] Multiple hard drive sub-bays, each hard drive sub-bay corresponding to one of the aforementioned hard drive mounting components;

[0016] Preferably, the surface of the hard drive mounting component is provided with a mounting groove, one end of which is open for extending the gold fingers of the hard drive out of the hard drive mounting component.

[0017] Preferably, the width and length of the mounting slot are greater than the length and width of the hard drive to be installed, and the depth of the mounting slot is greater than the thickness of the hard drive.

[0018] Preferably, the width of the opening is greater than the width of the gold finger and less than the width of the hard drive.

[0019] Preferably, one end of the hard disk mounting component is provided with a handle, and the handle is hinged to the hard disk mounting component;

[0020] When the handle rotates around the hinge, it abuts against the tail of the hard drive in the mounting slot, thereby pushing the hard drive toward one end of the opening.

[0021] Preferably, the modular bracket chassis has multiple insertion holes, and the clamping end has insertion blocks corresponding to the insertion holes. After the telescopic fastener clamps the multiple hard disk sub-compartments, the insertion blocks are inserted into the insertion holes to fix the modular hard disk compartments on the modular bracket chassis.

[0023] Preferably, the surface of the modular hard drive compartment is provided with multiple limiting blocks, and the limiting blocks correspond to the position of the handle after rotation.

[0024] The above technical solution has the following advantages or beneficial effects:

[0025] 1. Quick expansion without disassembly, significantly improving maintenance efficiency: With the design of the adsorption-type modular bracket chassis and pull-out hard drive mounting components, users can complete the hard drive insertion and removal without disassembling the chassis or motherboard, shortening the operation time and completely avoiding the risk of hardware damage caused by disassembly in traditional solutions (such as electrostatic damage, stripped screws), which is especially suitable for non-professional users.

[0026] 2. Break through motherboard interface limitations and achieve flexible expansion of multiple hard drives: Relying on the modular bracket chassis, a single motherboard interface (such as SATA / M.2) can be expanded into multiple sub-hard drive interfaces, supporting the simultaneous connection of multiple hard drives, solving the problem of scarce interfaces on home motherboards, and meeting advanced needs such as large-capacity storage and multi-system parallel operation.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within its scope.

[0041] In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, a modular, easily replaceable hard drive tray is provided, comprising:

[0042] Modular hard drive bay 1, which is equipped with multiple pull-out hard drive mounting components 2;

[0043] The modular bracket chassis 3 and the modular hard drive bay 1 are fixedly connected to the modular bracket chassis 3. The modular bracket chassis 3 is provided with multiple sub-hard drive interfaces 4 corresponding to the hard drive mounting parts 2. Each sub-hard drive interface 4 is electrically connected to the main interface 31 of the modular bracket chassis 3. The main interface 31 is electrically connected to the hard drive interface of the motherboard through an extension cable.

[0044] Specifically, such as Figure 1 and Figure 6 As shown, this invention innovatively proposes a modular, easily replaceable hard drive bracket system to address the problems of complex operation and poor scalability in traditional hard drive installation solutions. This system adopts a groundbreaking "dual-mode architecture + magnetic positioning + non-disassembly expansion" design concept, providing users with an unprecedented storage expansion experience through ingenious modular design and intelligent interface management.

[0045] The system consists of two core modules:

[0046] Modular hard drive bay 1: Features a drawer-style design with multiple independent hard drive mounting brackets 2. Each bracket 2 supports tool-less installation of 2.5-inch / 3.5-inch hard drives. A matrix of ventilation holes can be incorporated into the bay surface, working in conjunction with an external intelligent temperature control system to automatically adjust heat dissipation efficiency based on hard drive operating temperature, ensuring stable operation of the storage device.

[0047] Modular Chassis 3: As the core hub of the system, the chassis is crafted from high-strength alloy material with an anodized surface, combining aesthetics and durability. Its bottom integrates multiple neodymium magnetic adsorption units, generating an adsorption force of up to 1200 Gauss, ensuring stable attachment to any metal surface within the chassis (including side panels, bottom panels, back panels, etc.). The chassis internally features an intelligent interface matrix, supporting automatic switching between multiple protocols such as SAS / SATA / NVMe. Seamless protocol conversion is achieved through an FPGA chip, and with the main interface extension cable, it can flexibly connect to hard drive interfaces in different locations on the motherboard.

[0048] The innovative advantages of this system are reflected in:

[0049] Flexible deployment in three-dimensional space: Thanks to magnetic installation technology, users can freely attach the bracket base to the optimal position (such as near the heat dissipation holes or away from high-temperature areas) according to the internal space layout of the chassis, which optimizes heat dissipation efficiency and keeps the inside of the chassis clean and beautiful.

[0050] End-to-end maintenance without disassembly: From hard drive installation to interface connection, there is no need to disassemble the chassis side panel or motherboard. Users can simply insert and remove the hard drive using the drawer-type installation tool, which greatly reduces operation time compared to traditional solutions. It is especially suitable for scenarios requiring high-frequency hardware maintenance, such as e-sports hotels and edge computing devices.

[0051] Intelligent Protocol Adaptation: The chassis interface matrix supports automatic detection of hard drive protocol types (implemented using existing technologies, such as FPGA dynamic configuration technology, EEPROM information reading technology, or interface control chips that support multi-protocol auto-negotiation (such as the Marvell 88SE9485 SAS / SATA controller), automatically identifying the hard drive protocol type through physical layer signal characteristic recognition (such as voltage level and impedance characteristics) and protocol handshake packet detection (such as sending PHY layer training sequences). When replacing hard drives with different protocols, the system can automatically complete the protocol switching without manual configuration, greatly improving device compatibility.

[0052] Highly scalable: The modular design allows users to flexibly adjust the number of hard drives and interface types according to their needs. By replacing hard drive bays and interface modules of different specifications, the system can support various application scenarios from basic storage to high-performance computing, providing users with a great deal of upgrade potential.

[0053] This hard drive bay system not only solves the problems of complex operation and poor heat dissipation in traditional storage expansion solutions, but also brings unprecedented convenience and scalability to users through modular design and intelligent management. Whether for enterprise users seeking efficient operation and maintenance or individual users who value user experience, this system provides an ideal storage solution.

[0054] In a preferred embodiment of this utility model, the modular hard disk drive bay 1 includes:

[0055] Multiple hard drive sub-bays 11, each hard drive sub-bay 11 corresponds to a hard drive installation component 4;

[0056] Telescopic fastener 12 can clamp multiple hard drive sub-compartments 11 placed side by side at the same time.

[0057] Specifically, such as Figure 6 and Figure 7 The figure shows a top view and a right view of the modular hard disk compartment 1. As can be seen from the figure, the modular hard disk compartment 1 is assembled from multiple hard disk sub-compartments 11 placed side by side and clamped by a telescopic fastener 12.

[0058] In a preferred embodiment of this utility model, such as Figure 8 As shown, the telescopic fastener 12 includes a tensioning spring 121 and two clamping ends 122 disposed at both ends of the tensioning spring 121;

[0059] The distance between the two clamping ends 122 of the telescopic fastener 12 is adjustable and tightened by the tightening spring 121 to clamp different numbers of hard drive sub-compartments.

[0060] Furthermore, by tightening and stretching the tension spring 121 in the telescopic fastener 12, different numbers of hard drive sub-chambers 11 can be clamped. Through this modular design, the number of hard drive sub-chambers can be increased or decreased as needed to reduce the overall size.

[0061] In a preferred embodiment of this utility model, such as Figure 1 and Figure 8 As shown, the modular bracket chassis 3 has multiple insertion holes 32, and the clamping end 122 has insertion blocks 123 corresponding to the insertion holes 32. After the telescopic fastener 12 clamps the multiple hard disk sub-chambers 11, the insertion blocks 123 are inserted into the insertion holes 32 to fix the modular hard disk compartment 1 on the modular bracket chassis 3.

[0062] And further, such as Figures 1-5 As shown, the modular bracket chassis also adopts a modular design, which is assembled by multiple sub-chassis 33 arranged side by side. The number, position and width of the sub-chassis 33 correspond to those of the hard drive sub-chassis 11.

[0063] After the telescopic fastener 12 clamps the hard drive sub-chamber 11, the connector 123 is inserted into the connector hole to simultaneously clamp and assemble multiple sub-chambers 33 into a modular bracket chassis 3, and fix the modular hard drive chamber 1 on the modular bracket chassis 3, so as to achieve flexible modular assembly of the whole.

[0064] In a preferred embodiment of the present invention, the surface of the hard disk mounting component 2 is provided with a mounting groove 21, and one end of the mounting groove 32 is open for extending the gold fingers of the hard disk out of the hard disk mounting component 2.

[0065] In a preferred embodiment of the present invention, the width and length of the mounting slot 21 are greater than the length and width of the hard drive to be installed, and the depth of the mounting slot 21 is greater than the thickness of the hard drive.

[0066] In a preferred embodiment of this invention, the width of the opening is greater than the width of the gold finger but less than the width of the hard drive.

[0067] Specifically, such as Figure 9-11 As shown, a mounting slot 21 is provided on the surface of the hard drive mounting component 2. The hard drive is installed in the mounting slot 21. The dimensions (width, length, and depth) of the mounting slot 21 are all larger than the corresponding dimensions of the hard drive, providing ample space for the insertion and removal of the hard drive, reducing the difficulty of operation, and making it especially suitable for non-professionals to quickly complete the installation.

[0068] The opening width is greater than the gold fingers but less than the hard drive width. This ensures that the gold fingers can fully extend and contact the motherboard, while the shielding on both sides prevents physical damage to the gold fingers during installation due to collisions or friction (such as bending of the gold fingers or wear of the plating). At the same time, the opening and the hard drive can be pulled out during disassembly by abutting against each other.

[0069] The larger mounting slot can accommodate hard drives of different sizes (such as 2.5-inch and some 3.5-inch hard drives), improving device compatibility; at the same time, there is still room after the hard drive is installed, and with the limiting structure on both sides (such as adding silicone strips), the hard drive can be prevented from shifting due to vibration or impact during use.

[0070] In a preferred embodiment of the present invention, one end of the hard disk mounting component 2 is provided with a handle 22, and the handle 22 is hinged to the hard disk mounting component 2.

[0071] When the handle 22 is rotated around the hinge, it abuts against the tail of the hard drive in the mounting slot 21 to push the hard drive toward one end of the opening.

[0072] In a preferred embodiment of the present invention, the surface of the modular hard disk compartment 1 is provided with a plurality of limiting blocks 13, and the limiting blocks 13 correspond to the positions of the handle 22 after rotation.

[0073] Specifically, in this embodiment, as Figure 11-13 As shown, handle 22 is rotated around the hinge to push the hard disk toward one end of the opening.

[0074] The hinged handle allows users to push the hard drive towards the opening end directly using leverage with a simple turn. This design eliminates the need for two hands or tools in traditional installations, making it especially suitable for scenarios with limited space or where quick hard drive replacement is required.

[0075] When the handle is pushed towards the opening, the hard drive's gold fingers are precisely pushed to the deepest point of the motherboard slot. This mechanical positioning avoids poor contact problems caused by incomplete insertion of the gold fingers during manual installation, thus improving data transmission stability.

[0076] Once the handle is turned into place, its structure itself can serve as a rear securing device for the hard drive. Compared to traditional designs that rely solely on side latches, this adds... Figure 13 The convex limiting block 13 in the middle forms a three-point fixation (limiting blocks on both sides + tail handle), which effectively prevents the hard drive from shifting due to vibration or impact.

[0077] Installation can be completed without directly touching the hard drive's gold fingers, avoiding damage to sensitive electronic components caused by static electricity or accidental finger contact, making it particularly suitable for enterprise-level storage device maintenance scenarios.

[0078] In a preferred embodiment of the present invention, the bottom surface of the modular bracket chassis 3 is provided with a plurality of magnetic adsorption devices 34 for adsorbing the modular bracket chassis 3 onto any part of the computer host.

[0079] Specifically, such as Figure 2 As shown, the bottom surface of the modular bracket chassis 3 is equipped with multiple magnetic adsorption devices 34. The magnetic adsorption principle allows users to complete the installation without tools such as screwdrivers and screws, which is especially suitable for scenarios that require frequent disassembly and assembly or temporary expansion of storage devices, such as IT maintenance and e-sports equipment debugging.

[0080] Multiple magnetic adsorption devices 34 can adapt to different metal surfaces inside the host (such as the side panel of the chassis, the power supply compartment cover, etc.), breaking through the limitations of the fixed position of traditional hard drive racks and realizing flexible layout in three-dimensional space.

[0081] The portability allows users to adjust to a better heat dissipation location (such as near the heat dissipation holes) based on the internal temperature field distribution of the host, and with the modular design, it can even realize active heat dissipation path planning for hard drive arrays.

[0082] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present utility model.
