Description

Technical Field

[0001] This utility model relates to the field of computer cabinet hardware auxiliary equipment technology, specifically to a shock-absorbing structure for a cloud computer cabinet hard drive tray. Background Technology

[0002] With the rapid development of cloud computing technology, cloud computing cabinets, as the core carrier for data storage and processing, typically integrate multiple hard drives to meet large-scale data storage needs. However, cloud computing cabinets face two major problems in practical applications: First, hard drives generate continuous vibration during high-speed operation, and the vibrations can be superimposed when multiple hard drives are working simultaneously. If the vibrations cannot be effectively buffered, it can easily lead to increased friction between the hard drive heads and platters, which not only shortens the lifespan of the hard drives but may also cause data read / write errors or even data loss.

[0003] In the existing technology, some hard drive brackets are equipped with simple rubber pads for shock absorption, but the buffering capacity of the rubber pads is limited, and they are prone to aging and deformation after long-term use, resulting in a significant decrease in shock absorption effect. Other brackets use a fixed spring structure, but the preload of the spring cannot be adjusted, making it difficult to adapt to the weight of different models of hard drives and the shock absorption requirements under different operating conditions. At the same time, their assembly structure is complex, which is not convenient for the quick disassembly and maintenance of hard drives. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above in the background technology and to propose a shock-absorbing structure for a cloud computer cabinet hard drive tray.

[0005] The objective of this utility model can be achieved through the following technical solutions:

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 As shown, this utility model is a shock-absorbing structure for a cloud computer cabinet hard drive tray, including a bracket 2 and a frame 3 for supporting the hard drive. A cylindrical body 21 is recessed downward on the bracket 2. A lead screw 31 is provided on the frame 3 near the bracket 2. A ring-shaped cavity 22 is also provided between the lead screw 31 and the cylindrical body 21. A spring 33 is provided inside the cavity 22. A nut 32 is also threadedly connected to the lead screw 31 at the end of the cylindrical body 21.

[0025] A groove is provided on the inner wall of frame 3, and a hard drive fixing plate 4 is slidably engaged in the groove.

[0026] The side of the hard drive mounting plate 4 that is in contact with the hard drive protrudes outward to form a limiting protrusion 41.

[0027] The limiting protrusion 41 is made of a flexible material that can deform.

[0028] Spring 33 is a compression spring, and spring 33 is sleeved on lead screw 31.

[0029] The bracket 2 is also equipped with snap-fit ​​strips at both ends for fitting and engaging with the main frame 1.

[0030] The main frame 1 has strip grooves on both sides, and the snap-fit ​​strip can be snapped into the strip grooves.

[0031] The two strip grooves are a slide groove 11 and a slot 12. One end of the slide groove 11 has an opening, and the snap-fit ​​strip on one side of the bracket 2 can slide into the slide groove 11. The snap-fit ​​strip on the other side of the bracket 2 can be inserted horizontally into the slot 12.

[0032] The length of the slide 11 is greater than the length of the slot 12.

[0033] The bracket 2 is made of metal.

[0034] The main frame 1 can be made of 2.2mm thick cold-rolled steel plate (with electrostatic spraying anti-rust layer on the surface);

[0035] Bracket 2 can be made of 1.8mm thick 304 stainless steel;

[0036] Frame 3 can be made of 1.8mm thick 304 stainless steel;

[0037] The lead screw 31 can be made of 304 stainless steel;

[0038] Spring 33 can be made of 65Mn spring steel;

[0039] The hard drive mounting plate 4 can be made of 1.1mm thick ABS engineering plastic;

[0040] Assembly steps:

[0041] Assembly of the shock-absorbing core structure: Coaxially mount the spring 33 onto the lead screw 31 of the frame 3, push the bracket 2 so that the cylinder 21 fits into the lead screw 31 until one end of the spring 33 abuts against the bottom of the cylinder 21; screw the nut 32 into the lead screw 31, and screw it until the spring 33 is slightly compressed and the initial preload is about 8N, which is suitable for conventional hard drives, and completes the connection between the bracket 2 and the frame 3.

[0042] Hard drive mounting plate installation: Adjust the distance between the two hard drive mounting plates 4 by sliding along the strip groove on the inner wall of the frame 3 according to the width of the hard drive to ensure that the limiting protrusion 41 can fit tightly with the hard drive shell after the hard drive is placed in.

[0043] Assembly of bracket and main frame: Slide the snap-fit ​​strip on one side of bracket 2 into the opening of the slide groove 11 of main frame 1, and push bracket 2 to the preset position along the groove; insert the snap-fit ​​strip on the other side of bracket 2 horizontally into the slot 12 of main frame 1 until the end of the snap-fit ​​strip abuts against the inner wall of slot 12, and complete the overall assembly.

[0044] When the hard drive vibrates during operation or the cabinet is subjected to external impact, the vibration energy is transmitted sequentially to the frame 3 and the lead screw 31. The compression spring 33, which is sleeved on the lead screw 31, absorbs the energy through axial elastic deformation. The annular cavity 22 restricts the radial displacement of the spring 33, ensuring the stability of the shock absorption direction. At the same time, the silicone limiting protrusion 41 on the hard drive fixing plate 4 buffers the local vibration between the hard drive and the fixing plate through its own deformation, preventing the hard drive from sliding. The snap-fit ​​structure between the bracket 2 and the main frame 1 ensures that the bracket as a whole is not loose, further reducing the vibration transmission path and achieving all-round protection for the hard drive.

[0045] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent adjustments to the parameters of this embodiment, such as material replacement, size scaling, or equivalent improvements based on the structure of this utility model, within the scope of this utility model application, shall fall within the patent protection scope of this utility model.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
