Description

Technical Field

[0001] This invention relates to the field of storage technology, specifically to a protective device for a storage server and a storage server cabinet. Background Technology

[0002] Storage servers are critical devices in data centers and cloud computing systems for storing, managing, and backing up massive amounts of data. To achieve high storage density within limited space, a large number of hard drives are typically deployed in a single storage server rack. Hard disk drives (HDDs) contain precision moving parts and are extremely sensitive to vibration. Vibrations from the external environment (including equipment resonance, high-frequency fan vibration, transportation shocks, and maintenance operations) can directly transmit to the hard drive, causing instability between the read / write head and the platter, leading to read / write errors, seek delays, and in severe cases, platter scratches, bad sectors, or even permanent damage to the hard drive, resulting in the loss of critical data. Solid-state drives (SSDs), while having no moving parts, can still experience excessive vibration that can cause fatigue at circuit board solder joints and loosening of connectors, similarly affecting system reliability.

[0003] In existing technologies, storage servers and racks are mostly installed using rigid connection schemes. Specifically, the server body is directly fixed to the rack mounting columns using bolts or other fasteners, while the hard drives are directly fixed to the hard drive backplate or cage inside the server chassis using screws or clips on the brackets, forming a multi-layered rigid vibration transmission path of "rack-server chassis-hard drive bracket-hard drive". When an external vibration source generates excitation, the vibration energy is transmitted to the hard drive body along this path with almost no attenuation. Although some designs have simple rubber feet at the bottom of the rack, they can only isolate low-frequency vibrations and have limited damping travel. They cannot effectively suppress complex vibration environments with wide frequency bands and multiple directions, especially vibrations transmitted through the sides and front and back of the rack. Therefore, the rigid fixing method of pure bolt connection, lacking necessary buffering and energy dissipation links, is difficult to isolate multi-dimensional and wide-frequency vibrations generated by the external environment, significantly increasing the hard drive failure rate and the risk of data loss, thus restricting the application of storage servers in harsh vibration environments such as mobile data centers, vehicle / shipborne servers, and industrial sites. Summary of the Invention

[0004] This invention provides a protection device for a storage server and a storage server cabinet, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A protective device for a storage server includes a fixed frame, a movable frame disposed inside the fixed frame, the movable frame being detachably connected to the chassis, both the fixed frame and the movable frame being U-shaped structures, and also includes an auxiliary fixing mechanism and a buffer support mechanism.

[0007] An auxiliary fixing mechanism is provided between the chassis and the movable frame to fix the chassis to the inside of the movable frame;

[0008] The buffer support mechanism includes an inclined guide groove disposed on the side wall of the movable frame. The movable frame has two symmetrically arranged inclined guide grooves on the same side. The lower side of the inclined guide groove is open and inclined towards the center of the movable frame. The side wall of the fixed frame is provided with a support shaft that slides along the inner side of the inclined guide groove. The outer side of the fixed frame is provided with a buffer separation component. The buffer separation component is used to drive the two support shafts on the same side of the fixed frame to move closer to each other.

[0009] As a preferred embodiment of the present invention, the buffer separation assembly includes a fixed plate fixedly connected to the outside of the fixed frame, a guide post fixedly connected to the fixed plate, a slider slidably connected to the middle of the guide post, a support shaft connected to the side of the slider, a clearance groove provided on the side wall of the fixed frame, the support shaft passing through the clearance groove and slidingly engaging with the inclined guide groove, and a return spring sleeved on the guide post, one end of the return spring abutting against the fixed plate, and the other end of the return spring abutting against the slider.

[0010] As a preferred embodiment of the present invention, a limiting frustum is provided at one end of the support shaft near the center of the fixed frame. The diameter of the limiting frustum gradually decreases towards the center of the fixed frame, and the maximum diameter of the limiting frustum is greater than the width of the inclined guide groove. The support shaft is rotatably connected to the side of the slider.

[0011] As a preferred embodiment of the present invention, both the fixed frame and the movable frame have clearance openings on their back sides, and the movable frame has locking threaded holes on its front side for engaging with the chassis.

[0012] As a preferred embodiment of the present invention, the auxiliary fixing mechanism includes a slide rail detachably connected to the side wall of the chassis, and the inner side of the movable frame is provided with a slide groove that slides in cooperation with the slide rail.

[0013] A storage server rack includes a support column detachably connected to a fixed frame. A base plate is provided at the bottom of the support column, and a top plate is provided at the top of the support column. A cabinet door is provided between the base plate and the top plate, and the cabinet door is rotatably connected to the base plate and the top plate.

[0014] As a preferred embodiment of the present invention, the base plate is provided with a walking wheel on the side closest to the ground.

[0015] As a preferred embodiment of the present invention, the side of the support column is provided with a plurality of mounting holes, and the side wall of the fixing frame is slidably connected with mounting bolts, the mounting bolts passing through the mounting holes, and the mounting bolts are threaded with locking nuts that cooperate with the support column.

[0016] The present invention has the following advantages:

[0017] 1. Multi-dimensional buffering and efficient vibration reduction: By using a slanted guide groove in conjunction with a support shaft driven by a return spring, when the movable frame is subjected to vertical vibration, the support shaft slides along the slanted guide groove, inevitably generating horizontal displacement. This converts the vertical vibration energy into the elastic potential energy of the horizontal return spring. This structure can effectively absorb external vibration energy from multiple directions and a wide frequency band, significantly reducing the vibration intensity transmitted to the chassis and its internal hard drives, and greatly reducing the risk of read / write errors, platter scratches, and data loss caused by vibration.

[0018] 2. Automatic Centering and Pre-tightening Function: The conical design of the limiting frustum works in conjunction with the inclined guide groove sidewall to automatically push the movable frame to the center position after it is installed, eliminating the misalignment problem caused by machining or assembly errors in traditional rigid connections. Simultaneously, the continuous pre-tightening force provided by the return spring ensures that the movable frame and the fixed frame maintain a tight contact, preventing free wobbling while preserving a buffer stroke.

[0019] 3. Wide assembly adaptability and convenient operation: Two installation schemes (direct push-in and step-by-step lifting) are designed for chassis of different weights, suitable for efficient batch deployment of lightweight equipment, as well as labor-saving and safe installation of heavyweight equipment. The rotating connection design of the support shaft and slider further reduces frictional resistance during assembly, making the sliding frame push-in smoother.

[0020] 4. Significantly Improved Maintenance Convenience: The clearance design allows power and signal cables to remain connected during the movement of the movable frame, eliminating the need for repeated plugging and unplugging, greatly facilitating troubleshooting and online maintenance. The independent opening design of the front and rear cabinet doors allows operators to access the chassis from the front, manage cables from the rear, and adjust the buffer components from the side, without interference between operations.

[0021] 5. Highly modular and scalable: The fixed frame is height-adjustable via mounting bolts and evenly distributed mounting holes on the support columns. Users can configure the number of chassis layers and spacing as needed to accommodate storage servers of different specifications. The introduction of wheels enables the entire rack to be mobile, making it suitable for scenarios requiring frequent relocation, such as data centers, mobile shelters, and vehicle / shipborne deployments.

[0022] 6. High safety and reliable structure: The double fixing of the locking nut and mounting bolts, and the locking design of the cabinet door and support column, ensure the stability of the overall structure in moving or vibrating environments. At the same time, the design of the support shaft being able to actively exit the inclined guide groove during disassembly avoids damage to components or personal injury that may be caused by forcibly pulling it out.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In one embodiment, see Figure 1 , Figure 2 and Figure 5 A protective device for a storage server includes a fixed frame 3, inside which a movable frame 2 is disposed. Both the fixed frame 3 and the movable frame 2 are U-shaped structures, and their openings face forward. The movable frame 2 is smaller than the fixed frame 3, allowing it to be placed directly inside the fixed frame 3. The movable frame 2 is detachably connected to the outside of a chassis 1 via an auxiliary fixing mechanism 6, while the fixed frame 3 is used to connect to a subsequent storage server rack frame to enable multi-layer stacking of the chassis 1. A buffer support mechanism 7 is also provided between the fixed frame 3 and the movable frame 2. This mechanism can partially absorb vibration energy from the external frame, thereby effectively protecting the storage units such as hard drives inside the chassis 1.

[0038] In one instance of this embodiment, please refer to Figure 1 and Figure 2 The auxiliary fixing mechanism 6 is disposed between the inner wall of the movable frame 2 and the outer wall of the chassis 1. On the one hand, this mechanism is used to reliably connect the chassis 1 and the movable frame 2; on the other hand, when the chassis 1 is relatively light, the operator can directly use this mechanism to make the chassis 1 slide inside the movable frame 2, thereby quickly completing the installation and removal of the chassis 1.

[0039] Specifically, the auxiliary fixing mechanism 6 includes slide rails 4 detachably mounted on the outer walls of the left and right sides of the chassis 1, and corresponding slide grooves 5 disposed on the inner walls of the left and right sides of the movable frame 2. The front end of the slide groove 5 is open, allowing the slide rail 4 to slide smoothly into the slide groove 5 from front to back. The slide rail 4 and the chassis 1 can be fixed by snap-fit ​​or bolt connection. For a lighter chassis 1, the movable frame 2 can be pre-placed inside the fixed frame 3, and then the chassis 1 with the slide rail 4 can be directly pushed into the slide groove 5 to complete the assembly.

[0040] In one instance of this embodiment, please refer to Figures 1-8 The buffer support mechanism 7 is the core of this invention for achieving shock absorption and protection. This mechanism includes inclined guide grooves 12 formed on the left and right side walls of the movable frame 2. Two inclined guide grooves 12 are symmetrically arranged front and back on the same side wall of the movable frame 2. The lower end of each inclined guide groove 12 is open, and the upper end is closed, with the lower ends of both inclined guide grooves 12 inclined towards the center of the movable frame 2. In other words, the lower ends of the two inclined guide grooves 12 located at the front and rear of the same side wall are close together, forming an inverted "V" shape or a converging layout.

[0041] Correspondingly, support shafts 11 are respectively provided on the left and right side walls of the fixed frame 3, with two support shafts 11 on each side, which respectively cooperate with the two inclined guide grooves 12 on the movable frame 2. The support shafts 11 can slide along the inner wall of the inclined guide grooves 12. A buffer separation assembly 26 is also provided on the outer side of the fixed frame 3, which is used to drive the two support shafts 11 on the same side of the fixed frame 3 to move closer to each other.

[0042] Its working mechanism is as follows: When the movable frame 2 moves downward relative to the fixed frame 3 due to external vibration, the support shaft 11 slides upward along the inner wall of the inclined guide groove 12. During this process, due to the inclined design of the upper ends of the inclined guide groove 12 being far apart and the lower ends being close together, the distance between the two support shafts 11 gradually increases as they slide. However, the buffer separation component 26 applies a pre-tightening force that brings the two support shafts 11 closer together. Therefore, the forced separation movement of the support shafts 11 and the tightening effect of the buffer separation component 26 counteract each other, thereby converting the vibration energy into the elastic potential energy inside the buffer separation component 26, achieving buffering and energy absorption.

[0043] The buffer separation assembly 26 includes clearance grooves 16 formed at the front and rear ends of the left and right side walls of the fixed frame 3. Fixed plates 8, fixedly connected to the fixed frame 3, are respectively provided on the front and rear sides of the clearance grooves 16. A guide post 9 extending in the front-rear direction is fixedly connected between the two fixed plates 8, and a slider 10 is slidably connected to the middle of the guide post 9. The side of the slider 10 closest to the center of the fixed frame 3 is connected to the end of the support shaft 11. A return spring 13 is sleeved on the outside of the guide post 9, with its two ends abutting against the sides of the fixed plate 8 and the slider 10, respectively. The return spring 13 constantly pushes the two sliders 10 closer together, thereby providing a continuous reset and buffering force.

[0044] In one instance of this embodiment, please refer to Figure 5 and Figure 6 A limiting frustum 15 is provided at one end of the support shaft 11 near the center of the fixed frame 3. The diameter of the limiting frustum 15 gradually decreases towards the center of the fixed frame 3, i.e., it is conical or frustum-shaped, and the maximum diameter of the limiting frustum 15 is greater than the width of the inclined guide groove 12. When the limiting frustums 15 on the left and right sides extend into the inclined guide groove 12, the inclined surface of the limiting frustum 15 will contact the side wall of the inclined guide groove 12, driving the movable frame 2 to move towards the center of the fixed frame 3, thereby achieving the effect of automatic centering. At the same time, this inclined surface engagement also ensures that the movable frame 2 always has a tendency to move towards the center, further enhancing the buffer stability.

[0045] Furthermore, the support shaft 11 and the slider 10 are rotatably connected. Therefore, during the process of placing the movable frame 2 into the fixed frame 3, the bottom side of the movable frame 2 can first rest on the support shaft 11. At this time, the support shaft 11 can be passively rotated, allowing the movable frame 2 to move back and forth more smoothly, which facilitates positioning and fixing.

[0046] In one instance of this embodiment, please refer to Figure 1 and Figure 5 Both the fixed frame 3 and the movable frame 2 have clearance openings 14 on their back sides. After both are fixed, operators can connect the power interface and signal interface at the rear of the chassis 1 through the clearance openings 14. During the movement of the chassis 1 back and forth by the movable frame 2, the power cable or signal cable can still move freely through the clearance openings 14, allowing the chassis 1 to be pulled out of the fixed frame 3, greatly facilitating maintenance and repair.

[0047] A locking threaded hole 25 is provided at the front end of the movable frame 2. A locking bolt is provided at the corresponding position at the front end of the conventional chassis 1. After the chassis 1 slides into the movable frame 2, the chassis 1 and the movable frame 2 can be fixed together by tightening the locking bolt and engaging with the locking threaded hole 25. Afterward, the chassis 1 can move together with the movable frame 2 inside the fixed frame 3.

[0048] This invention also provides a storage server rack; please refer to [link / reference]. Figures 9-11 The system includes the protective device described above, and four symmetrically arranged support columns 18. Each support column 18 has multiple mounting holes 20 evenly distributed from top to bottom on its side. Mounting bolts 21 are provided at the front and rear ends of the left and right side walls of the fixed frame 3, and the mounting bolts 21 are slidably connected to the fixed frame 3. During installation, first slide the mounting bolts 21 towards the center of the fixed frame 3 to avoid misalignment, place the fixed frame 3 at the predetermined height between the four support columns 18, then push the mounting bolts 21 outwards and insert them into the corresponding mounting holes 20, and finally tighten the locking nut 22 at the end of the mounting bolt 21 to reliably fix the fixed frame 3 to the support columns 18.

[0049] A base plate 17 is fixedly connected to the bottom of the support column 18, and a top plate 19 is fixedly connected to the top. The three together form a rectangular frame structure to support the multi-layer fixed frame 3. A cabinet door 23 is provided between the base plate 17 and the top plate 19. The upper and lower ends of the cabinet door 23 are rotatably connected to the base plate 17 and the top plate 19 through pivots. The side of the cabinet door 23 is provided with a latch, and the support column 18 is provided with a corresponding lock. The front cabinet door 23 can be rotated open to facilitate the operator to put in and take out the chassis 1; after the left and right cabinet doors 23 are opened, it is easy to manually adjust the slider 10 so that the support shaft 11 slides into the inclined guide groove 12; after the rear cabinet door 23 is opened, it is easy to connect the power cable and the signal cable.

[0050] The base plate 17 is equipped with four corners at its lower surface. The casters 24 are preferably self-locking casters, which allow the entire cabinet to move freely and lock after reaching the target position to ensure operational stability.

[0051] (a) Initial rack assembly process (without chassis 1 installed)

[0052] Step 1: Install the walking wheels 24 onto the lower surface of the base plate 17.

[0053] Step 2: Assemble the support column 18 and top plate 19 with the bottom plate 17 to form a frame structure (the cabinet door 23 is not installed at this time).

[0054] Step 3: Select an appropriate number of mounting frames 3 according to the working height requirements of chassis 1. Insert the mounting bolts 21 of each mounting frame 3 into the mounting holes 20 at the corresponding height on the support column 18, and tighten the lock nuts 22 to complete the fixing of the mounting frames 3 and the support column 18.

[0055] (II) Installation process of lightweight chassis 1

[0056] If chassis 1 is relatively lightweight, follow these steps:

[0057] Step 1: Place the movable frame 2 into the fixed frame 3 beforehand. Manually adjust the position of the sliders 10 on the left and right sides of the cabinet so that the support shafts 11 slide into the inclined guide grooves 12 on both sides of the movable frame 2.

[0058] Step 2: Install the slide rail 4 on the left and right side walls of the chassis 1.

[0059] Step 3: Lift the chassis 1, align the rear end of the slide rail 4 with the front opening of the slide groove 5 on the inner wall of the movable frame 2, and push the chassis 1 smoothly from front to back.

[0060] Step 4: After the chassis 1 is completely slid into the movable frame 2, tighten the locking bolts at the front end of the chassis 1 to fix it in place with the locking threaded hole 25 at the front end of the movable frame 2, thus completing the installation of the chassis 1.

[0061] (III) Installation process of heavy machine box 1

[0062] If chassis 1 is heavy, follow these steps:

[0063] Step 1: On the external workbench, first install the slide rails 4 on both sides of the chassis 1, then align the slide grooves 5 of the movable frame 2 with the slide rails 4, push the chassis 1 into the movable frame 2 from front to back, and tighten the locking bolts to fix the chassis 1 and the movable frame 2 into a whole component.

[0064] Step 2: Lift the entire assembly and insert it into the fixed frame 3 from front to back. Ensure the bottom side of the movable frame 2 rests on the support shaft 11 on the front side of the fixed frame 3.

[0065] Step 3: Continue to push the entire component backward, so that the active frame 2 gradually enters the depth of the fixed frame 3.

[0066] Step 4: After reaching the predetermined position, operate the rear slider 10 to move the rear support shaft 11 forward and slightly lift the front end of the chassis 1, so that the rear support shaft 11 slides into the lower end of the inclined guide groove 12 on the rear side of the movable frame 2. After confirming that the rear support shaft 11 is against the closed upper end of the inclined guide groove 12, operate the front slider 10 to make the front support shaft 11 slide into the lower end of the front inclined guide groove 12.

[0067] Step 5: Slowly release chassis 1. Under the weight of chassis 1 itself, the support shafts 11 on the front and rear sides will slide upward along the inclined guide groove 12 for a certain distance, and finally stabilize in the middle position of the inclined guide groove 12. At this time, the return spring 13 is in a pre-compressed state, providing continuous cushioning and centering force.

[0068] (iv) Finishing work after the rack installation is completed

[0069] After all chassis 1 are installed, perform the following operations:

[0070] Step 1: Connect the power cable and signal cable of chassis 1 from the rear through the clearance port 14.

[0071] Step 2: Install the cabinet doors 23 on the front, left and right sides and the back side between the bottom plate 17 and the top plate 19 respectively, and lock each cabinet door 23 to the support column 18 by using the latch and lock head.

[0072] Step 3: If you need to move the cabinet, unlock the wheels 24 and push it to the target position, then lock the wheels 24 again.

[0073] (v) Detailed steps of the disassembly process

[0074] When it is necessary to disassemble an assembled server rack:

[0075] Step 1: Open the rear cabinet door 23 and disconnect all power cables and signal cables connected to the chassis 1.

[0076] Step 2: Open the left and right cabinet doors 23 and the front cabinet door 23.

[0077] For the lightweight chassis 1: simply loosen the locking bolts at the front of chassis 1 to release chassis 1 from the movable frame 2, and then pull chassis 1 out directly through the cooperation of slide rail 4 and slide groove 5.

[0078] For heavy chassis 1:

[0079] Step 1: Slightly lift the front end of the chassis 1 to disengage the front support shaft 11 from the inclined guide groove 12. Operate the front slider 10 to pull the front support shaft 11 outward, so that it is completely removed from the inclined guide groove 12.

[0080] Step 2: Slightly press down on the front end of the housing 1 to make the rear side of the movable frame 2 tilt upwards. Operate the rear slider 10 to disengage the rear support shaft 11 from the rear inclined guide groove 12.

[0081] Step 3: Pull the chassis 1 forward. At this time, the support shaft 11 on the front side of the lower edge of the movable frame 2 will slide forward until the entire assembly is completely pulled out of the fixed frame 3.

[0082] Step 4: Separate the chassis 1 from the movable frame 2 to complete the disassembly.

[0083] This invention provides a protective device for a storage server and a storage server cabinet. Through the cooperation of the inclined guide groove 12 and the support shaft 11 driven by the return spring 13, vertical vibration is converted into horizontal elastic potential energy, achieving efficient multi-dimensional buffering and significantly reducing the risk of data loss due to hard drive vibration. The conical design of the limiting frustum 15 automatically centers the movable frame 2, and the spring preload eliminates swaying, improving operational stability. For different weight chassis 1, direct push-in or step-by-step lifting installation solutions are provided, and the rotating connection of the support shaft 11 makes assembly smooth and convenient. The clearance opening 14 allows cables to remain connected during chassis 1 movement, and the independently opening cabinet door 23 facilitates partitioned operation and online maintenance. The height of the fixed frame 3 is adjustable, and the cabinet is equipped with casters 24, providing good modular expansion capabilities and mobility flexibility. Multiple fixing structures and the active withdrawal design of the support shaft 11 further ensure operational safety and structural reliability.

[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
