Description

Technical Field

[0001] This application relates to the field of computer equipment technology, specifically to a hard disk bracket and a server. Background Technology

[0002] Hard drives are an indispensable part of storage servers and industrial control computers, and hard drive brackets, as the load-bearing structure of hard drives, not only serve to fix the hard drives in place, but also to reduce the vibration of the hard drives.

[0003] Currently, there are many types of hard drives on the market, with varying specifications, sizes, and other parameters. The hard drive brackets provided in servers and industrial control computers typically have a simple structure and are incompatible with hard drives of different sizes, impacting user experience. Furthermore, most hard drive brackets use screws to secure the hard drive, requiring a screwdriver for both installation and removal, which is time-consuming, laborious, and inconvenient. Utility Model Content

[0004] In view of the above problems, this application provides a hard drive bracket and server, which can not only install and fix hard drives of different sizes, but also improve the efficiency and convenience of hard drive installation and removal.

[0005] According to one aspect of the embodiments of this application, a hard drive bracket is provided, the hard drive bracket comprising: a mounting base having a mounting position for placing a hard drive; an abutment side plate slidably disposed on at least one side of the mounting position along a first direction; a limiting frame disposed on the side of the abutment side plate away from the mounting position and slidably connected to the mounting base along the first direction, a first elastic member abutting between the limiting frame and the abutment side plate, the limiting frame being used to push the abutment side plate toward the mounting position by the first elastic member when sliding toward the mounting position, so that the abutment side plate abuts against one side of the hard drive; and a pressing assembly vertically and vertically disposed on the limiting frame along a second direction, used to at least partially move to the top of the mounting position when the limiting frame slides toward the mounting position, and used to press the hard drive firmly when descending relative to the limiting frame, wherein the second direction is perpendicular to the first direction; the pressing assembly is also used to allow space at the top of the mounting position when the limiting frame slides in a direction away from the mounting position.

[0006] In one alternative embodiment, the hard drive bracket further includes a drive assembly disposed on a limiting frame and drivenly connected to a pressing assembly. The drive assembly is used to drive the pressing assembly to move up and down relative to the limiting frame to press or release the hard drive placed on the mounting base in a second direction.

[0007] In one alternative approach, there are multiple crimping components arranged along a third direction, and all of the crimping components are vertically movable on the limiting frame along a second direction, wherein the third direction is perpendicular to both the first and second directions; a drive component is connected to all the crimping components and is used to drive all the crimping components to move synchronously up and down relative to the limiting frame, so as to simultaneously press or release the hard drive placed on the mounting base along the second direction at multiple positions arranged along the third direction.

[0008] In one alternative embodiment, the drive assembly includes a worm gear and a turbine, the worm gear being rotatably connected to the limit frame, the turbine being drive-connected to the worm gear, and the turbine being drive-connected to the pressing assembly. The turbine is used to rotate under the drive of the worm gear to drive the pressing assembly to move up and down relative to the limit frame.

[0009] In one alternative embodiment, the crimping assembly includes a lead screw and a pressure rod. The lead screw is vertically and vertically mounted on a limiting frame in a second direction. A worm gear is sleeved on the lead screw and threadedly connected to it. The lead screw and the pressure rod are fixedly connected. The lead screw is used to drive the pressure rod to move at least partially to the top of the mounting position when the limiting frame slides toward the mounting position. The worm gear is used to drive the lead screw and the pressure rod to move vertically and vertically in the second direction when rotating, so that the pressure rod presses or releases the hard drive. The lead screw is also used to drive the pressure rod to make way for the space at the top of the mounting position when the limiting frame slides away from the mounting position.

[0010] In one alternative embodiment, the limiting frame is provided with a first mating component, and the pressing assembly further includes a second mating component, which is fixedly connected to the lead screw and the pressure rod respectively, and the second mating component and the first mating component are slidably mated in a second direction.

[0011] In one alternative embodiment, the mounting base is provided with fixing plates at both ends along a third direction, and the limiting frame is provided with support arms extending towards the mounting position at both ends along the third direction. The support arms at both ends are slidably connected to the fixing plates at both ends along a first direction, wherein the third direction is perpendicular to both the first and second directions. At least one fixing plate is provided with a first positioning hole, and the support arm slidably connected to the fixing plate with the first positioning hole is provided with a second positioning hole. The hard drive bracket also includes a snap-fit ​​shaft, which is retractable in the first positioning hole. The snap-fit ​​shaft is used to partially extend out of the first positioning hole and insert into the second positioning hole when the limiting frame slides towards the mounting position to the locking position, so as to lock the mounting base and the limiting frame. The snap-fit ​​shaft is also used to unlock the limiting frame and the mounting base when it withdraws from the second positioning hole and retracts into the first positioning hole.

[0012] In one alternative embodiment, the support arm is connected to the side of the fixed plate opposite to the mounting position. The hard drive bracket also includes a bushing, which is fixedly mounted on the fixed plate with a first positioning hole and communicates with the first positioning hole. The snap-fit ​​shaft is telescopically disposed within the first positioning hole and the bushing, and the bushing is used to abut against the snap-fit ​​shaft to limit the maximum telescopic stroke. The end of the snap-fit ​​shaft opposite to the mounting position is provided with an inclined surface, which is used to abut against the support arm when the limiting frame slides toward the mounting position, so that the snap-fit ​​shaft is compressed back into the first positioning hole by the support arm. A second elastic element is also sleeved on the snap-fit ​​shaft, and the two ends of the second elastic element abut against the snap-fit ​​shaft and the bushing, respectively. The second elastic element is used to push the snap-fit ​​shaft part out of the first positioning hole and insert into the second positioning hole when the limiting frame slides toward the mounting position to the locking position.

[0013] In one alternative embodiment, a cable connector is installed at one end of the mounting base, which is connected to the hard drive to secure the hard drive in the mounting position; the other end of the mounting base may also be detachably provided with an abutment plate, at least one end of which is detachably connected to an abutment side plate, and the abutment plate abuts against one end of the hard drive.

[0014] According to another aspect of the embodiments of this application, a server is provided, the server including a chassis, a hard drive and a hard drive bracket provided in any of the above embodiments; the hard drive bracket is installed in the chassis and is used to support and fix the hard drive.

[0015] The hard drive bracket provided in this application embodiment, by sliding an abutment side plate to at least one side of the mounting position of the mounting base, and by sliding a limiting bracket to the side of the abutment side plate away from the mounting position, allows a first elastic member abutting between the abutment side plate and the limiting bracket to push the abutment side plate towards the mounting position when the limiting bracket slides towards the mounting position, thereby abutting the abutment side plate against the hard drive placed on the mounting position and clamping the hard drive along the width direction (horizontal direction); by lifting and lowering a pressing assembly on the limiting bracket, the pressing assembly can move to the top of the mounting position under the action of the limiting bracket, and by adjusting the pressing assembly to lower it and press the hard drive along the height direction, the hard drive is fixed. In this method, since the hard drive is clamped by horizontal sliding and lifting movement, when installing hard drives of different sizes, it is only necessary to adjust each component to the corresponding position to clamp the hard drive to achieve compatibility with hard drives of different sizes. In addition, when the limiting bracket slides away from the mounting position, it can also make the crimping component avoid the space at the top of the mounting position, so as to ensure that the hard drive can be easily put into or taken out of the mounting position, making the installation and removal of the hard drive more convenient and improving the efficiency of hard drive installation and removal. Furthermore, since no screws are needed, wear and damage to the hard drive can be avoided during the repeated use of tools to tighten screws.

[0037] Currently, there are many types of hard drives on the market, with varying specifications and dimensions. The hard drive brackets provided with most computers have a single, unreliable structure, making them incompatible with hard drives of different sizes and impacting user experience. Furthermore, most hard drive brackets use screws to secure the drives, requiring at least four screws for each drive. This necessitates the use of a screwdriver for installation and removal, which is not only inefficient and cumbersome, wasting considerable time and effort, but also increases the risk of wear and damage to the hard drive and the potential for screws to be lost due to repeated use of tools to tighten the screws.

[0038] Based on this, this application provides a hard drive bracket that clamps the hard drive horizontally using a horizontally sliding abutment side plate and vertically pressing the hard drive using a liftable pressing component, thereby achieving the installation and fixation of the hard drive. In this method, since the abutment side plate and pressing component are movable, technicians can easily operate them by hand. When installing hard drives of different sizes, simply slide the abutment side plate and pressing component to the position that matches the corresponding size of the hard drive to clamp and press it, thus achieving compatibility with hard drives of different sizes. This makes the installation and removal of hard drives more convenient and improves the efficiency of hard drive installation and removal. Furthermore, since no screws are needed, wear and damage to the hard drive can be avoided during the repeated use of tools to tighten screws.

[0039] Please see Figures 1-4 , Figure 1 A perspective view of the hard drive bracket provided in an embodiment of this application is shown. Figure 2 This paper shows a schematic diagram of the hard drive bracket provided in an embodiment of the present application. Figure 3 This paper shows a schematic diagram of the hard drive bracket provided in an embodiment of the present application. Figure 4 An exploded view of a hard disk bracket provided in an embodiment of this application is shown. As shown in the figure, the hard disk bracket 10 includes: a mounting base 100, an abutment side plate 200, a limiting bracket 300, and a pressing assembly 400.

[0040] The mounting base 100 has a mounting position 110 for placing the hard disk 20. An abutment side plate 200 is slidably disposed on at least one side of the mounting position 110 along a first direction. A limiting bracket 300 is disposed on the side of the abutment side plate 200 opposite to the mounting position 110 and is slidably connected to the mounting base 100 along the first direction. A first elastic member 310 abuts between the limiting bracket 300 and the abutment side plate 200. When the limiting bracket 300 slides toward the mounting position 110, the first elastic member 310 pushes the abutment side plate 200 toward the mounting position 110, so that the abutment side plate 200 abuts against one side of the hard disk 20.

[0041] The crimping assembly 400 is vertically and vertically mounted on the limiting frame 300 along a second direction. It is used to move at least partially to the top of the mounting position 110 when the limiting frame 300 slides towards the mounting position 110, and to press the hard disk 20 firmly when descending relative to the limiting frame 300. The second direction is perpendicular to the first direction. The crimping assembly 400 is also used to clear space above the top of the mounting position 110 when the limiting frame 300 slides away from the mounting position 110.

[0042] The first direction and the second direction are the directions indicated by the x-arrow and z-arrow in the diagram, respectively, which are the width direction and the height direction of the hard drive 20, hereinafter referred to as the width direction and the height direction. The mounting position 110 can accommodate at least 3.5-inch and 2.5-inch hard drives 20.

[0043] like Figure 4 As shown, a slidable abutment side plate 200 can be provided on one side of the mounting base 100, and a fixed side plate 101 can be provided on the other side; alternatively, slidable abutment side plates 200 can be provided on both sides of the mounting base 100. A groove 120 can be provided on the bottom plate of the mounting base 100 along a first direction, and a slider 210 adapted to the groove 120 can be provided at the bottom of the abutment side plate 200. By sliding the slider 210 into the groove 120, the abutment side plate 200 can slide on the mounting base 100 along the width direction. Furthermore, the groove 120 can be set as a T-shaped groove, which can prevent the slider 210 from disengaging from the mounting base 100 along the height direction when sliding in the groove 120, thus avoiding failure of the sliding fit between the slider 210 and the groove 120.

[0044] Specifically, it is possible to install such a device along the width direction at both ends of the mounting base 100. Figure 4 The first guide structure 130 shown is provided on both sides of the limiting frame 300 along the width direction as follows: Figure 4 The second guide structure 320 shown cooperates with the first guide structure 130. For example, the first guide structure 130 and the second guide structure 320 are a slider and a groove, or a groove and a slider, respectively. Through the sliding cooperation of the first guide structure 130 and the second guide structure 320, the limiting frame 300 can be stably slid back and forth in the width direction. Optionally, the first guide structure (not shown in the figure) can also be installed at the bottom of the mounting base 100 in the width direction, and a second guide structure (not shown in the figure) adapted to the first guide structure can be provided at the bottom of the limiting frame 300 in the width direction.

[0045] The first elastic element 310 can be a spring. Optionally, a through hole (not shown in the figure) can be opened on the abutting side plate 200, and a crossbar (not shown in the figure) can be provided on the limiting frame 300 along the width direction. By sleeved the first elastic element 310 on the crossbar, and then passing the two ends of the crossbar through the above-mentioned through hole and rotatably connected to the limiting frame 300 and the abutting side plate 200 respectively, the two ends of the first elastic element 310 can abut against the limiting frame 300 and the abutting side plate 200 respectively.

[0046] The limiting frame 300 is disposed on the side of the abutting side plate 200 away from the mounting position 110, and the first elastic member 310 abuts against the limiting frame 300 and the abutting side plate 200 respectively. When the limiting frame 300 slides towards the mounting position 110, the first elastic member 310 begins to be in a compressed state. At the same time, the elastic force of the first elastic member 310 pushes the abutting side plate 200 to slide towards the mounting position 110 until the abutting side plate 200 abuts against one side of the hard disk 20, thus fixing the hard disk 20 along the width direction.

[0047] It should be noted that when both sides of the mounting base 100 are slidably provided with abutment side plates 200, a locking structure can be provided so that the abutment side plate 200 that is not in contact with the first elastic member 310 can be locked with the mounting base 100 through the above-mentioned locking structure after sliding to the preset position. This ensures that when the limit frame 300 slides toward the mounting position 110, the first elastic member 310 can push the other abutment side plate 200 to slide toward the mounting position 110 until the two abutment side plates 200 respectively abut with the two sides of the hard disk 20.

[0048] A portion of the crimping assembly 400 extends along the width direction, such that when the limiting bracket 300 slides toward the mounting position 110, the portion of the crimping assembly 400 can... Figure 3 The assembly 400 is moved to the top of the mounting position 110 as shown. The crimping assembly 400 is raised and lowered on the limiting bracket 300, and a portion of the crimping assembly 400 is raised and lowered above the mounting position 110 accordingly. Furthermore, the portion of the crimping assembly 400 can also... Figure 1 As shown, it descends until a portion of the crimping assembly 400 abuts against the top surface of the hard disk 20, thereby pressing the hard disk 20 onto the mounting position 110 and fixing the hard disk 20 along the height direction.

[0049] Alternatively, an opening (not shown in the figure) may be made in the abutment side panel 200, or as... Figure 4 The through hole 201 is shown, wherein both the opening and the through hole 201 extend along the height direction. By placing part of the crimping assembly 400 in the opening or through the through hole 201, when the crimping assembly 400 is raised and lowered on the limit frame 300, part of the crimping assembly 400 can be raised and lowered above the mounting position 110 along the opening or through hole 201, thereby improving the stability of the raising and lowering of the crimping assembly 400.

[0050] In the above situation, the first elastic member 310 can be sleeved on the part of the crimping assembly 400 located between the limiting frame 300 and the abutting side plate 200, so that when the limiting frame 300 slides toward the mounting position 110, the two ends of the first elastic member 310 abut against the limiting frame 300 and the abutting side plate 200 respectively as the crimping assembly 400 moves toward the mounting position 110, pushing the abutting side plate 200 to slide toward the mounting position 110 until it abuts against one side of the hard disk 20, thereby simultaneously fixing the hard disk 20 in two directions through the crimping assembly 400.

[0051] In some embodiments, since the first elastic member 310 is in direct contact with the abutting side plate 200, the frictional resistance between the first elastic member 310 and the abutting side plate 200 may cause difficulty in raising and lowering the crimping assembly 400 when the first elastic member 310 moves up and down along the opening or through hole 201 above the mounting position 110. To solve this problem, it is possible to... Figure 2 and Figure 4 A guide 311 is fitted onto the portion of the crimping assembly 400 between the first elastic member 310 and the abutting side plate 200. The guide 311 can isolate the first elastic member 310 from the abutting side plate 200. When the crimping assembly 400 is raised or lowered above the mounting position 110, the guide 311 can guide the first elastic member 310 to rise or fall above the mounting position 110 along with the crimping assembly 400.

[0052] After raising the crimping assembly 400 to release the hard drive 20, the limiting bracket 300 is slid away from the mounting position 110, thus moving part of the crimping assembly 400 away from the mounting position 110. Figure 2 The space at the top of the mounting position 110 is cleared to allow the hard disk 20 to be removed from the mounting position 110.

[0053] In some embodiments, in order to improve the stability of the crimping assembly 400 in fixing the hard disk 20 along the height direction, the portion of the crimping assembly 400 located at the top of the mounting position 110 can be configured as a plate structure to increase the contact area between the crimping assembly 400 and the top surface of the hard disk 20, so that the crimping assembly 400 can more smoothly press and fix the hard disk 20 onto the mounting base 100.

[0054] The hard drive bracket 10 provided in this application embodiment achieves this by sliding the abutment side plate 200 on at least one side of the mounting position 110 of the mounting base 100, and by sliding the limiting frame 300 to the side of the abutment side plate 200 away from the mounting position 110, so that the first elastic member 310 abutting between the abutment side plate 200 and the limiting frame 300 can push the abutment side plate 200 toward the mounting position 110 when the limiting frame 300 slides toward the mounting position 110, so as to abut the abutment side plate 200 against the hard drive 20 placed on the mounting position 110, thereby clamping the hard drive 20 along the width direction (horizontal direction); by lifting and lowering the pressing assembly 400 on the limiting frame 300, the pressing assembly 400 can move to the top of the mounting position 110 under the drive of the limiting frame 300, and by adjusting the pressing assembly 400 to lower it and press the hard drive 20 along the height direction, the hard drive 20 is fixed. In this method, since the hard drive 20 is clamped by horizontal sliding and lifting movement, when installing hard drives 20 of different sizes, simply adjusting each component to the corresponding position and clamping the hard drive 20 achieves compatibility with hard drives 20 of different sizes. Furthermore, when the limiting bracket 300 slides away from the mounting position 110, it also allows the pressing component 400 to avoid space above the mounting position 110, ensuring that the hard drive 20 can be easily placed into or removed from the mounting position 110. This makes the installation and removal of the hard drive 20 more convenient and improves the efficiency of installation and removal. Moreover, since no screws are needed, wear and damage to the hard drive 20 can be avoided during repeated screw tightening with tools.

[0055] To enable the pressing assembly 400 to move vertically and horizontally on the limiting frame 300, this application further proposes an implementation method. Please refer to the following: Figures 1-4 As shown in the figure, the hard disk bracket 10 also includes a drive assembly 500, which is disposed on the limiting frame 300 and is connected to the crimping assembly 400. The drive assembly 500 is used to drive the crimping assembly 400 to move up and down relative to the limiting frame 300, so as to press or release the hard disk 20 placed on the mounting base 100 in the second direction.

[0056] Specifically, the drive assembly 500 can be a device that drives a gear with a pulley or a device that drives a worm gear.

[0057] For example, the drive assembly 500 may include a pulley (not shown) and a gear (not shown), both of which are rotatable on the limit frame 300. The pulley and gear mesh with each other, allowing the pulley to drive the gear to rotate. A thread is provided on the inner ring of the gear, and the gear is threadedly connected to the pressing assembly 400. That is, by rotating the pulley counterclockwise or clockwise, the gear can be driven to rotate counterclockwise or clockwise, thus causing the pressing assembly 400 to descend or rise along the height direction. This allows a portion of the pressing assembly 400 to press or release the hard drive 20 at different heights.

[0058] The drive assembly 500 may further include a worm gear 510 and a turbine gear 520. The two ends of the worm gear 510 are respectively fitted with through holes 301 on both sides of the limit frame 300, allowing the worm gear 510 to rotate on the limit frame 300. The turbine gear 520 meshes with the worm gear 510, allowing the turbine gear 520 to rotate as the worm gear 510 rotates. By providing threads on the inner ring of the worm gear 510 and threadedly connecting the worm gear 510 to the pressing assembly 400, the pressing assembly 400 can move up and down in the height direction as the worm wheel 520 rotates. For example, when the worm gear 510 rotates counterclockwise, it drives the worm wheel 520 to rotate counterclockwise, which in turn drives the crimping assembly 400 to descend in the height direction. When the worm gear 510 rotates clockwise, it drives the worm wheel 520 to rotate clockwise, which in turn drives the crimping assembly 400 to rise in the height direction. Of course, the worm gear 510 and worm wheel 520 can also rotate counterclockwise to drive the crimping assembly 400 to rise, and rotate clockwise to drive the crimping assembly 400 to descend. Optionally, when the worm gear 510 stops rotating, the worm gear 510 and worm wheel 520 can be self-locked, thereby enabling the crimping assembly 400 to rise or fall to any position, realizing the pressing or releasing of the hard drive 20 at different heights.

[0059] like Figure 1 and Figure 4 As shown, to rotate the worm gear 510, a knob 511 can be provided at at least one end of the worm gear 510. By threading the knob 511 to the worm gear 510, the worm gear 510 can be rotated clockwise or counterclockwise onto the limit frame 300 by rotating the knob 511. Thus, the hard disk 20 at different heights can be pressed or released by manually rotating the knob 511. Furthermore, a serrated anti-slip texture can be provided on the knob 511 to increase the friction when rotating the knob 511, making it easier to rotate the worm gear 510.

[0060] To improve the stability of the crimping assembly 400 in fixing the hard disk 20 along the height direction, this application further proposes an embodiment, please refer to the following: Figures 1-4As shown in the figure, there are multiple crimping assemblies 400, which are arranged along a third direction and are vertically movable on the limiting frame 300 along a second direction. The third direction is perpendicular to both the first and second directions. The drive assembly 500 is connected to all the crimping assemblies 400 and drives all the crimping assemblies 400 to move synchronously up and down relative to the limiting frame 300, so as to simultaneously press or release the hard disk 20 placed on the mounting base 100 along the second direction at multiple positions arranged along the third direction.

[0061] The third direction is the direction indicated by arrow y in the figure, which is the length direction of hard disk 20, hereinafter referred to as the length direction.

[0062] Specifically, it can be like Figures 1-4 As shown, multiple crimping components 400 are arranged at equal intervals along the length direction, or multiple crimping components 400 can be arranged without intervals along the length direction. By using multiple crimping components 400 to press the hard disk 20 at different positions, the ability to fix the hard disk 20 in the height direction is greatly improved.

[0063] When multiple pressing components 400 are provided, the aforementioned drive components 500 can be provided accordingly. For example, multiple gears can be threadedly connected to multiple pressing components 400 one by one, and pulleys can be meshed with multiple gears so that the pulleys can simultaneously drive multiple gears to rotate synchronously, thereby driving multiple pressing components 400 to move up and down synchronously, and simultaneously pressing or releasing the hard disk 20. Alternatively, multiple turbines 520 can be threadedly connected to multiple pressing components 400 one by one, and worm gears 510 can be meshed with multiple turbines 520 so that the worm gears 510 can simultaneously drive multiple turbines 520 to rotate synchronously, thereby driving multiple pressing components 400 to move up and down synchronously, and simultaneously pressing or releasing the hard disk 20.

[0064] Optionally, when multiple crimping components 400 are provided, multiple first elastic elements 310 can be provided, and the multiple first elastic elements 310 are respectively fitted one by one onto the portion of each crimping component 400 located between the limiting frame 300 and the abutting side plate 200. When the multiple crimping components 400 slide towards the mounting position 110 as the limiting frame 300 slides, the multiple first elastic elements 310 can simultaneously push the abutting side plate 200 to slide towards the mounting position 110 until it abuts against one side of the hard disk 20, thereby enhancing the fixing ability of the hard disk 20 in the width direction.

[0065] To achieve the clamping or releasing of the hard disk 20, this application further proposes an implementation method, please refer to [further details]. Figures 1-4 and combined Figure 5 , Figure 5A cross-sectional view of the hard drive bracket provided in an embodiment of this application is shown. As shown in the figure, the crimping assembly 400 includes a lead screw 410 and a pressure rod 420. The lead screw 410 is vertically and vertically mounted on the limiting frame 300 along a second direction. A turbine 520 is sleeved on the lead screw 410 and threadedly connected to the lead screw 410. The lead screw 410 and the pressure rod 420 are fixedly connected. The lead screw 410 is used to drive the pressure rod 420 to at least partially move to the top of the mounting position 110 when the limiting frame 300 slides toward the mounting position 110. The turbine 520 is used to drive the lead screw 410 and the pressure rod 420 to move vertically and vertically along the second direction when rotating, so that the pressure rod 420 presses or releases the hard drive 20. The lead screw 410 is also used to drive the pressure rod 420 to avoid space at the top of the mounting position 110 when the limiting frame 300 slides away from the mounting position 110.

[0066] Specifically, the compression bar 420 can be as follows: Figure 4 One end can be provided with a cylindrical structure, and the other end can be provided with a bushing. The cylindrical structure can reduce the frictional resistance generated between the pressure rod 420 and the abutting side plate 200 during the lifting process. The bushing is sleeved on one end of the lead screw 410, which can fix the pressure rod 420 and the lead screw 410 together.

[0067] like Figure 3 and 4 As shown, one end of the pressure rod 420 with a cylindrical structure passes through the through hole 201 on the abutting side plate 200. When the limiting frame 300 slides toward the mounting position 110, the lead screw 410 slides in the same direction, driving the pressure rod 420 to slide in the same direction, so that the pressure rod 420 moves to the top of the mounting position 110, until the end of the pressure rod 420 with the cylindrical structure enters or even passes through the through hole 201 on the fixed side plate 101 (or another abutting side plate 200). In this case, a first elastic member 310 can be sleeved on the part of the pressure rod 420 located between the limiting frame 300 and the abutting side plate 200, so that when the pressure rod 420 moves toward the mounting position 110, the first elastic member 310 pushes the abutting side plate 200 to slide toward the mounting position 110 until it abuts against one side of the hard disk 20.

[0068] Combination Figure 3 and Figure 4 As shown, one end of the lead screw 410 is fixedly connected to the pressure rod 420, and the other end of the lead screw 410 is threadedly connected to the turbine 520. When the turbine 520 rotates counterclockwise, it can drive the lead screw 410 and the pressure rod 420 to descend along the height direction, thereby driving the pressure rod 420 to descend until it presses the hard disk 20. When the turbine 520 rotates clockwise, it can drive the lead screw 410 and the pressure rod 420 to rise along the height direction, releasing the hard disk 20.

[0069] After the pressure lever 420 rises to release the hard drive 20, when the limit bracket 300 slides away from the mounting position 110, the lead screw 410 slides in the same direction and drives the pressure lever 420 to slide in the same direction, so that the pressure lever 420 avoids the space at the top of the mounting position 110, making it easier to remove the hard drive 20 from the mounting position 110.

[0070] In some embodiments, such as Figure 4 and Figure 5 As shown, the turbine 520 may include a first body 521 and a second body 522. A hollow column 302 is fixedly mounted on the limiting frame 300, and a bearing 303 is disposed within the hollow column 302. By fixing the inner wall of the hollow column 302 to the outer ring 303a of the bearing 303, the bearing 303 can be fixedly disposed within the hollow column 302. By interfering with the inner ring 303b of the bearing 303, the turbine 520 and the bearing 303 can be fixed together on the hollow column 302 and can rotate synchronously on the hollow column 302. Furthermore, a thread can be provided on the inner wall of the first body 521 to thread the first body 521 to one end of the lead screw 410, so that when the turbine 520 rotates on the hollow column 302, it can drive the lead screw 410 to move up and down. Optionally, a rolling element 303c can be provided between the outer ring 303a and the inner ring 303b of the bearing 303 to improve the performance and life of the bearing 303 through the lubrication effect of the rolling element 303c.

[0071] To make the lifting and lowering movement of the pressure rod 420 smoother, this application further proposes an implementation method, please refer to the following: Figure 3 and Figure 4 As shown in the figure, the limiting frame 300 is provided with a first mating part 304, and the pressing assembly 400 also includes a second mating part 430. The second mating part 430 is fixedly connected to the lead screw 410 and the pressure rod 420 respectively, and the second mating part 430 and the first mating part 304 slide in a second direction.

[0072] The first mating part 304 can be a cylinder fixedly mounted on the limit frame 300, and the second mating part 430 can be a bushing. Of course, the first mating part 304 can also be a bushing fixedly mounted on the limit frame 300, and the second mating part 430 can be a cylinder.

[0073] By fitting the first mating part 304 onto the second mating part 430, or fitting the second mating part 430 onto the first mating part 304, the second mating part 430 can slide along the first mating part 304, thereby driving the pressure rod 420 to slide along the height direction, improving the stability of the lifting and lowering movement of the lead screw 410 and the pressure rod 420.

[0074] In some embodiments, when the first mating part 304 is a cylinder and the second mating part 430 is a bushing, the inner diameter of the second mating part 430 can be slightly larger than the diameter of the first mating part 304. When the second mating part 430 is a cylinder and the first mating part 304 is a bushing, the diameter of the second mating part 430 can be slightly smaller than the inner diameter of the first mating part 304, thereby reducing the frictional force between the first mating part 304 and the second mating part 430, and further reducing the resistance when the lead screw 410 and the pressure rod 420 move up and down with the second mating part 430.

[0075] To lock or unlock the mounting base 100 and the limiting bracket 300, this application further proposes an implementation method; please refer to the following section. Figure 3 and Figure 4 and combined Figure 6 and Figure 7 , Figure 6 Another cross-sectional view of the hard drive bracket provided in an embodiment of this application is shown. Figure 7 A schematic diagram of the snap-fit ​​shaft provided in this application embodiment is shown. As shown in the figure, the mounting base 100 has fixing plates 140 at both ends along the third direction (height direction), and the limiting frame 300 has support arms 330 extending towards the mounting position 110 at both ends along the third direction. The support arms 330 at both ends are slidably connected to the fixing plates 140 at both ends along a first direction, wherein the third direction is perpendicular to both the first and second directions. At least one fixing plate 140 has a first positioning hole 141, and the support arm 330 slidably connected to the fixing plate 140 with the first positioning hole 141 has a second positioning hole 331. The hard drive bracket 10 also includes a locking shaft 600, which is telescopically retractable in the first positioning hole 141. The locking shaft 600 is used to partially extend out of the first positioning hole 141 and insert into the second positioning hole 331 when the limit bracket 300 slides to the mounting position 110 to the locking position, so as to lock the mounting base 100 and the limit bracket 300 together. The locking shaft 600 is also used to unlock the limit bracket 300 and the mounting base 101 when it exits from the second positioning hole 331 and retracts into the first positioning hole 141.

[0076] Specifically, the two fixing plates 140 can be located on opposite sides of the two support arms 330. Slide rails or sliders can be provided along the width direction on the opposite sides of the two fixing plates 140, and sliders or slide rails adapted to the slide rails or sliders can be provided along the width direction on the opposite sides of the two support arms 330, so that the fixing plates 140 and the support arms 330 are slidably connected along the width direction. Alternatively, the two fixing plates 140 can be located on opposite sides of the two support arms 330, and slide rails or sliders can be provided along the width direction on the opposite sides of the two fixing plates 140. Slide rails or slide rails adapted to the slide rails or sliders can be provided along a first direction on the opposite sides of the two support arms 330, so that the fixing plates 140 and the support arms 330 are slidably connected along the width direction.

[0077] In this embodiment of the application, a first positioning hole 141 may be provided on one of the fixing plates 140, and a second positioning hole 331 may be provided on the support arm 330 that is slidably connected to the fixing plate 140 with the first positioning hole 141. Alternatively, the first positioning hole 141 may be provided on both fixing plates 140, and the second positioning hole 331 may be provided on both support arms 330.

[0078] The number of snap-fit ​​shafts 600 corresponds to the number of first positioning holes 141.

[0079] Specifically, the locking position refers to the position where the limiting bracket 300 slides towards the mounting position 110 until the first positioning hole 141 and the second positioning hole 331 coincide. In the unlocked state, the locking shaft 600 passes through the first positioning hole 141 and is partially located outside the first positioning hole 141. When the limiting bracket 300 slides towards the mounting position 110 to install and fix the hard drive 20, the portion of the locking shaft 600 located outside the first positioning hole 141 retracts into the first positioning hole 141 under the pressure of the support arm 330. When the limiting bracket 300 slides towards the mounting position 110 to the locking position, the portion of the locking shaft 600 extends out of the first positioning hole 141 and inserts into the second positioning hole 331, locking the mounting base 100 and the limiting bracket 300 together. At this time, the side plate 200 is used to fix the hard drive 20 along the width direction. When removing the hard drive 20, the locking shaft 600 can be manually removed from the second positioning hole 331 and retracted into the first positioning hole 141 to unlock the mounting base 100 and the limiting bracket 300. Then, the limiting bracket 300 is slid away from the mounting position 110. At this time, it slides in the same direction to abut against the side plate 200 to release the fixation of the hard drive 20, and the hard drive 20 can be removed.

[0080] To enable the locking and unlocking of the locking shaft 600 and the limiting bracket 300, this application further proposes an embodiment; please refer to the following. Figure 3 , Figure 4 , Figure 6 and Figure 7As shown in the figure, the support arm 330 is connected to the side of the fixing plate 140 opposite to the mounting position 110. The hard disk bracket 10 also includes a bushing 150, which is fixedly mounted on the fixing plate 140 with a first positioning hole 141 and communicates with the first positioning hole 141. The snap-fit ​​shaft 600 is telescopically disposed within the first positioning hole 141 and the bushing 150, and the bushing 150 is used to abut against the snap-fit ​​shaft 600 to limit the maximum telescopic stroke.

[0081] The end of the snap-fit ​​shaft 600 facing away from the mounting position 110 is provided with an inclined surface 601. The inclined surface 601 is used to abut against the support arm 330 when the limit frame 300 slides toward the mounting position 110, so that the snap-fit ​​shaft 600 is squeezed and retracted into the first positioning hole 141 by the support arm 330.

[0082] A second elastic element 610 is also sleeved on the snap-fit ​​shaft 600. The two ends of the second elastic element 610 abut against the snap-fit ​​shaft 600 and the bushing 150 respectively. The second elastic element 610 is used to push the snap-fit ​​shaft 600 part out of the first positioning hole 141 and insert it into the second positioning hole 331 when the limit frame 300 slides to the mounting position 110 to the locking position.

[0083] In this embodiment, the two opposing sides of the two support arms 330 are slidably connected to the opposing sides of the two fixing plates 140. The bushing 150 can be welded and fixed to the fixing plate 140, so that the center of the bushing 150 is on the same horizontal line as the center of the first positioning hole 141, and the bushing 150 can communicate with the first positioning hole 141.

[0084] like Figure 6 and Figure 7 As shown, the snap-fit ​​shaft 600 can be a stepped shaft including a first shaft body 620 and a second shaft body 630. One end of the first shaft body 620 is provided with a bevel 601, and the other end is connected to one end of the second shaft body 630. The other end of the second shaft body 630 passes through the bushing 150 and is provided with a limiting member 160, wherein the limiting member 160 can be a nut, which is threadedly connected to the second shaft body 630. The end of the first shaft body 620 with the bevel 601 passes through the first positioning hole 141, and the other end can be located in the first positioning hole 141 or in the bushing 150. The end of the second shaft body 630 connected to the first shaft body 620 can be located in the first positioning hole 141 or in the bushing 150.

[0085] Specifically, an abutment wall with a through hole can be provided at the end of the bushing 150 facing away from the fixing plate 140. This abutment wall of the bushing 150 can prevent the first shaft 620 from completely disengaging from the bushing 150 in the direction of the mounting position 110. Furthermore, the diameter of the through hole in the abutment wall is larger than the inner diameter of the limiting member 160, so that the limiting member 160 can prevent the end of the second shaft 630 passing through the limiting member 160 from completely entering the bushing 150 in the direction away from the mounting position 110. It should be noted that the bushing 150 is clearance-fitted with the first shaft 620 and the second shaft 630.

[0086] In this embodiment, the second elastic element 610 can be a spring. The second elastic element 610 can be sleeved on the second shaft 630, wherein the inner diameter of the second elastic element 610 is larger than the diameter of the first shaft 620, the outer diameter of the second elastic element 610 is larger than the diameter of the through hole of the abutment wall of the bushing 150, and the second elastic element 610 is always in a compressed state, so that both ends of the second elastic element 610 can abut against the abutment walls of the first shaft 620 and the bushing 150 respectively.

[0087] During the sliding of the limiting frame 300 toward the mounting position 110, when the support arm 330 begins to abut against the inclined surface 601, the first shaft 620 retracts into the first positioning hole 141 under the compression of the support arm 330. During this process, the abutting wall of the bushing 150 can prevent the locking shaft 600 from disengaging from the first positioning hole 141 toward the mounting position 110. When the limiting frame 300 continues to slide to the locking position, the first shaft 620 extends out of the first positioning hole 141 under the elastic force of the second elastic member 610 and inserts into the second positioning hole 331 to lock the mounting base 100 with the limiting frame 300. During this process, the limiting member 160 can prevent the locking shaft 600 from disengaging from the bushing 150 in the direction away from the mounting position 110.

[0088] In some embodiments, a lever 161 can be provided on the limiting member 160, and a plate-like structure can be provided along the length direction on the side of the fixing plate 140 where the bushing 150 is fixed, with an L-shaped opening 142 formed in the plate-like structure. One end of the lever 161 can be threadedly connected and fixed to the limiting frame 133, and the other end passes through the L-shaped opening 142. When the mounting base 100 is locked with the limiting frame 300, the lever 161 moves as follows. Figure 8 As shown, located at one end of the L-shaped opening 142, when the mounting base 100 and the limiting frame 300 are to be unlocked, the lever 161 is moved along the L-shaped opening 142 to the other end of the L-shaped opening 142 and locked at the other end of the L-shaped opening 142. This allows the first shaft 620 to exit the second positioning hole 331 and retract back into the first positioning hole 141, thereby unlocking the mounting base 100 and the limiting frame 300.

[0089] In order to enable the hard drive bracket 10 to accommodate hard drives 20 of different lengths and sizes, this application further proposes an embodiment. Please refer to the following section. Figures 2-4 As shown in the figure, a cable plug 170 is installed at one end of the mounting base 100. The cable plug 170 is connected to the hard disk 20 to fix the hard disk 20 on the mounting position 110. The other end of the mounting base 100 is also detachably provided with an abutment plate 180. At least one end of the abutment plate 180 is detachably connected to the abutment side plate 200, and the abutment plate 180 abuts against one end of the hard disk 20.

[0090] In this mounting base 100, a notch for placing the cable connector 170 can be made on one of the fixing plates 140. Through holes 102 are made on the fixing plates 140 on both sides of the notch, and through holes 171 are made at both ends of the cable connector 170. The through holes 102 can also be U-shaped holes. When the cable connector 170 is placed in the notch and the through holes 171 are aligned with the through holes 102, fasteners 172 are used to securely connect the through holes 102 and 171, thus fixing the cable connector 170 to one end of the mounting base 100. When the hard drive 20 is installed in the mounting position 110, the cable connector 170 is inserted into the hard drive 20, thus securing the hard drive 20 to the mounting position 110. Optionally, both the through holes 102 and 171 can be threaded holes, and the fasteners 172 can be screws.

[0091] Specifically, limiting members 181 can be provided at both ends of the abutting end plate 180, and first limiting holes 202 and second limiting holes 203 can be provided on the two abutting side plates 200 or on the abutting side plate 200 and the fixed side plate 101 respectively. The positions of the first limiting holes 202 and the second limiting holes 203 can be set according to the length of the hard disk 20.

[0092] Taking the example of setting a first limiting hole 202 and a second limiting hole 203 on the abutting side plate 200 and the fixed side plate 101 respectively, after the hard disk 20 is inserted into the cable plug 170, by passing the limiting member 181 at one end of the abutting end plate 180 through the first limiting hole 202 or the second limiting hole 203 on the fixed side plate 101, during the process of the limiting bracket 300 sliding towards the mounting position 110, the abutting side plate 200 slides in the same direction under the pushing action of the first elastic member 310, so that the limiting member 181 at the other end of the abutting end plate 180 passes through the first limiting hole 202 or the second limiting hole 203 on the abutting side plate 200. Thus, through the cooperation of the limiting member 181 with the first limiting hole 202 or the second limiting hole 203, the abutting end plate 180 is fixed to the other end of the mounting base 100, and the 3.5-inch or 2.5-inch hard disk 20 is fixed along the length direction.

[0093] The limiting member 181 can be configured as a retractable structure. For example, one of the limiting members 181 can be configured as a retractable structure, or both of the limiting members 181 can be configured as retractable structures, so that the abutting end plate 180 can fix the hard disk 20 of different widths along the length direction.

[0094] According to another aspect of the embodiments of this application, a server is provided, the server including a chassis, a hard drive, and a hard drive bracket provided in any of the above embodiments. The hard drive bracket is installed inside the chassis for supporting and securing the hard drive.

[0095] By installing hard drive brackets inside the server, compared to the structure of gradually tightening hard drives with a single screw, maintenance personnel do not need to use other tools. They can simply operate by hand to lock or unlock the hard drives and fix them along the height and width directions. This not only makes it compatible with hard drives of different sizes, but also makes the installation and removal of hard drives more convenient and improves the efficiency of hard drive installation and removal. Furthermore, since no screws are used, wear and damage to the hard drives can be avoided during the repeated use of tools to tighten screws.
