Description

Hard disk tray, hard disk module and server

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 14, 2023, with application number 202311716969.4 and application name “Hard disk bracket, hard disk module and server”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of computer technology, and in particular to a hard disk bracket, a hard disk module and a server. Background Art

[0004] Hard drives are the primary storage devices in computers. To secure hard drives, a hard drive tray is required. In related technologies, hard drives are fixed inside a tray and plugged into a slot in the computer chassis. The tray is removably connected to the slot to prevent the hard drive from falling out. However, the large space occupied by the tray limits the hard drive's use and reduces the number of hard drives that can be supported by the server.

[0005] Summary of the Invention

[0006] In view of this, the present application provides a hard disk bracket, a hard disk module and a server to solve the problem in the related art that the hard disk bracket limits the use range of the hard disk width direction space, thereby reducing the number of hard disks that the server can support.

[0007] In a first aspect, the present application provides a hard disk tray, comprising:

[0008] The bracket body is adapted to be arranged at the first end of the hard disk; the hard disk is adapted to be inserted into a slot of the chassis, and the first end of the hard disk is located at the notch of the slot;

[0009] a first connecting structure, detachably connecting the bracket body and the first end of the hard disk;

[0010] The second connecting structure is detachably connected to the bracket body and the notch of the slot.

[0011] Beneficial Effects: The hard drive bracket of the present application is connected to the first end of the hard drive via a first connecting structure and is detachably connected to the notch of the chassis slot via a second connecting structure. This ensures that both the hard drive bracket and the hard drive are connected at the first end of the hard drive, as well as the hard drive bracket and the chassis slot are connected. Furthermore, because the hard drive bracket is fixed to the first end of the hard drive, when the hard drive is inserted into the slot, the hard drive bracket can be partially located outside the slot, thereby reducing the space occupied by the hard drive bracket along the length of the hard drive.

[0012] The hard drive bracket of the embodiment of the present application only needs to occupy space along the length of the hard drive and does not need to extend between the hard drive and the slot of the chassis, thereby increasing the width or thickness of the hard drive. This avoids the problem of the hard drive bracket occupying space along the width or thickness of the hard drive, which limits the usable space in the width or thickness direction of the hard drive, or restricts the layout space of components on the hard drive backplane. The hard drive bracket of the present application can solve the problem in the related art that the hard drive bracket limits the usable space along the width of the hard drive, thereby reducing the number of hard drives that can be supported by the server.

[0013] In an optional embodiment, the orthographic projection of the bracket body toward the hard disk is located within the end surface of the first end of the hard disk.

[0014] Beneficial effect: It can prevent the bracket body from increasing the thickness or width of the hard disk, resulting in limited space usage in the width or thickness direction of the hard disk, or limiting the device layout space on the hard disk backplane.

[0015] In an optional embodiment, the bracket body includes a first wall, the first wall is adapted to abut against the first end of the hard disk, and a first opening is provided on a side of the bracket body away from the hard disk;

[0016] The first connection structure includes a first connection hole and a fastener. The first connection hole is formed on the first wall. The fastener is suitable for passing through the first opening and the first connection hole in sequence and connecting to the hard disk.

[0017] Advantageous effect: Through such an arrangement, the bracket body can be reliably fixed at the first end of the hard disk, and occupies a small space.

[0018] In an optional embodiment, the second connecting structure includes: a lever structure, including a hinged end and an operating end, the hinged end is hinged to the first end of the bracket body along the length direction and is arranged in the first opening, and the operating end is detachably connected to the second end of the bracket body along the length direction, and the lever structure is suitable for assisting the hard disk to be plugged in or out of the slot.

[0019] Beneficial effect: The operator can first separate the operating end of the lever structure from the second end of the bracket body along the length direction, and then hold the operating end of the lever structure and apply force through the operating end to assist in plugging or unplugging the hard disk into or out of the slot, which can reduce the plugging and unplugging force required for disassembling the hard disk, making the disassembly and assembly process more labor-saving and reducing the labor intensity of the operator.

[0020] In an optional embodiment, the hinged end is detachably hinged to the first end of the bracket body along the length direction.

[0021] Beneficial effect: In the related art, the portion of the hard disk tray located at the first end of the hard disk is generally used to set a connecting structure connected to the slot of the chassis. There is no space for accommodating the connecting structure connecting the hard disk and the hard disk tray, resulting in the connecting structure for connecting to the hard disk and the hard disk tray being generally set on the side of the hard disk. The hard disk tray needs to be set to partially extend between the slot of the chassis and the hard disk, occupying the space on both sides of the hard disk along the width direction.

[0022] The hard disk tray of this embodiment has a hinged end disposed in the first opening and is detachably connected to the first end of the tray body along the length direction. When the hard disk tray needs to be installed on the hard disk, the operator can first pass the fastener through the first opening and the first connecting hole in sequence, connect the hard disk tray to the first end of the hard disk, and then connect the hinged end to the first opening.

[0023] When the hard drive needs to be repaired or replaced, the operator can first separate the hinged end of the lever structure from the bracket body and then remove the fastener through the first opening. This arrangement ensures that the connection between the hard drive bracket and the hard drive, as well as the connection between the hard drive bracket and the slot in the chassis, can be completed at the first end of the hard drive, and the hard drive bracket can be removed from the hard drive bracket for reuse.

[0024] In an optional embodiment, the bracket body also includes a second wall and a third wall, which are respectively connected to the two ends of the first wall along the thickness direction of the bracket body, and a second connecting hole and a threaded hole are respectively provided on the second wall and the third wall. The second connecting structure also includes a first hinge shaft, which passes through the second connecting hole and the hinge end in sequence and is threadedly connected to the threaded hole.

[0025] Beneficial effect: Through such a setting, when the lever structure needs to be installed on the bracket body, the operator can first place the hinge part into the first opening, then pass the first hinge shaft through the second connecting hole and the hinge end in sequence, and finally rotate the first hinge shaft and thread the first hinge shaft to the threaded hole to complete the assembly of the lever structure.

[0026] When the lever structure needs to be removed from the bracket body, the operator can reversely rotate the first hinge shaft to release the threaded connection between the first hinge shaft and the threaded hole, and then withdraw the first hinge shaft. Because the threaded hole is provided on the third wall, there is no need to use a nut to limit the first hinge shaft, thus avoiding the need to increase the thickness of the bracket body.

[0027] In an optional embodiment, the lever structure also includes a first abutment protrusion, which is formed at the hinge end of the lever structure, and an abutment groove is formed on the groove wall of the slot. When the operating end is connected to the second end of the bracket body, the first abutment protrusion abuts against the groove wall of the abutment groove. When the operating end moves in a direction away from the hard disk, the first abutment protrusion is suitable for disengaging from the abutment groove.

[0028] Beneficial Effect: With this arrangement, when inserting a hard drive into a slot, the operator can first place the hard drive in the slot and then rotate the operating end toward the hard drive, thereby facilitating the connection of the hard drive to the slot through the cooperation of the second abutting protrusion and the abutting groove. Once the operating end is connected to the second end of the bracket body along its length, the first abutting protrusion is constrained within the abutting groove, thereby preventing the hard drive from being dislodged from the slot due to external force or misoperation.

[0029] In an optional embodiment, the second connection structure further includes:

[0030] The second abutting protrusion is connected to the hinge end, and the second abutting protrusion abuts against the notch of the slot.

[0031] Beneficial effect: When the operator applies force to the operating end of the lever structure, forcing the operating end to rotate in the direction away from the hard disk, the hinged end of the lever structure can rotate in the opposite direction, so that the second abutting protrusion applies pressure to the notch of the slot, so that the hard disk can be disengaged from the slot under the reaction force at the notch.

[0032] In an optional embodiment, an abutment slope is formed at the first end of the bracket body along the length direction. When the operating end moves in a direction away from the hard disk, the second abutment protrusion is suitable for abutting against the notch and the abutment slope of the slot in sequence.

[0033] Beneficial effect: Through such an arrangement, when the lever structure is opened to the maximum angle, the abutting inclined surface can abut against the second abutting protrusion and limit the lever structure.

[0034] In an optional embodiment, the second connection structure further includes:

[0035] a first elastic member supported between the lever structure and the bracket body, and adapted to drive the lever structure to rotate in a direction away from the hard disk;

[0036] a lock catch movably connected to the second end of the bracket body, having a locked position in which it is locked with the operating end of the lever structure, and an unlocked position in which it is separated from the operating end;

[0037] The second elastic member is supported between the lock buckle and the bracket body, and the lock buckle is suitable for being located in a locking position under the support of the second elastic member.

[0038] Beneficial effect: Through such a setting, when the hard disk needs to be installed in the slot, the operator can drive the operating end to move toward the direction close to the hard disk and compress the first elastic member. The lock can be locked and connected with the operating end under the support of the second elastic member. At this time, the first abutment protrusion can be constrained in the abutment groove, thereby preventing the hard disk from falling out of the slot under the action of external force or due to misoperation.

[0039] When the hard drive needs to be removed from the slot, the operator applies force to the latch and compresses the second elastic member to switch the latch to an unlocked position separated from the operating end, thereby releasing the connection between the operating end and the second end of the bracket body along the length direction. The operating end can rotate away from the housing under the elastic force of the first elastic member, allowing the first abutment protrusion to disengage from the abutment groove. At the same time, the second abutment protrusion applies pressure to the slot opening, causing the hard drive to be removed from the slot due to the reaction force of the slot opening.

[0040] In an optional embodiment, a first abutment portion is formed on the bracket body, and the lever structure further comprises:

[0041] The first torsion spring groove is formed on the hinge end of the lever structure. The first elastic member is a first torsion spring. The first torsion spring is sleeved on the first hinge shaft and inserted into the first torsion spring groove. The two ends of the first torsion spring respectively abut against the groove wall of the first torsion spring groove and the first abutment portion.

[0042] Beneficial effect: Through such a setting, when the operating end is locked and connected with the lock, the groove wall of the first torsion spring groove can compress the two ends of the first torsion spring. When the lock is switched to the unlocked position, the first torsion spring can restore its original state through its own elastic restoring force and drive the operating end to rotate in the direction away from the hard disk.

[0043] In an optional embodiment, a second abutment portion is formed at the second end of the bracket body, and the lock includes:

[0044] a hinge portion hingedly connected to the second end of the bracket body;

[0045] a second hinge shaft passing through the bracket body and the hinge portion;

[0046] a third abutting protrusion connected to the hinge portion and adapted to abut against the operating end of the lever structure;

[0047] a manipulation portion connected to the hinge portion;

[0048] The second torsion spring groove is formed on the hinge part. The second elastic member is a second torsion spring. The second torsion spring is sleeved on the second hinge shaft and inserted into the second torsion spring groove. The two ends of the second torsion spring are respectively abutted against the groove wall of the second torsion spring groove and the second abutment part.

[0049] Beneficial Effect: When the operating end moves toward the hard drive under the action of an external force, the operating end first interferes with the first abutting protrusion, causing the first abutting protrusion to rotate in a direction approaching the hard drive, allowing the operating end to enter between the first abutting protrusion and the hard drive. Subsequently, the lock catch, supported by the second torsion spring, is locked in the locked position, causing the third abutting protrusion to abut against the operating end, preventing the operating end from falling out of the first opening.

[0050] When the hard drive needs to be removed from the slot, the operator can apply force to the operating part and compress the second torsion spring to make the lock rotate in the opposite direction and move to the unlocked position, allowing the operating end to rotate away from the hard drive under the elastic force of the first torsion spring.

[0051] In an optional embodiment, the first connection hole includes a second hole. The second hole is disposed at a second end of the bracket body along the length direction. The hard disk bracket further includes a cover plate that is detachably disposed over the first opening at the second end of the bracket body along the length direction, and is adapted to conceal the fastener.

[0052] Beneficial effect: The cover plate can be arranged on the first opening corresponding to the second hole to avoid exposure of the fastener, which helps to improve the aesthetics of the hard disk.

[0053] In an optional embodiment, the cover plate is inserted into the bracket body through the first opening at the second end of the bracket body in the length direction.

[0054] Beneficial effect: The bracket body can limit the cover plate by accommodating it, so as to avoid the cover plate taking up extra space.

[0055] In an optional embodiment, the cover plate includes a shielding portion and a cantilever, one end of the cantilever is connected to the shielding portion, and the other end is suspended in the direction of insertion between the cover plate and the first opening, a limiting protrusion is formed on the cantilever, and a limiting groove suitable for accommodating the limiting protrusion is formed on the inner wall of the first opening;

[0056] And / or, a stop portion is formed on the inner wall of the first opening, and the stop portion is suitable for abutting against the insertion end of the cover plate.

[0057] Beneficial Effect: When the cover is inserted into the first opening, the limiting protrusion first contacts the inner wall of the first opening and compresses the cantilever. When the cover is fully installed, the limiting protrusion enters the limiting groove and secures the cover within the first opening. The shielding portion shields the first opening from exposure, preventing fasteners from being exposed, thereby enhancing the aesthetics of the hard drive.

[0058] When the cover plate is installed in place, the stop portion can abut against the insertion end of the cover plate and prevent the cover plate from further entering the first opening, making it inconvenient for the operator to remove the cover plate from the first opening.

[0059] In an optional embodiment, the hard disk bracket further includes a light guide column, which is disposed in the bracket body and extends from the first wall of the bracket body to the first opening.

[0060] Beneficial effects: In related technologies, the hard disk bracket generally extends the side of the hard disk, and the light guide column is located between the side of the hard disk and the hard disk bracket, and extends from the second end of the hard disk to the first end of the hard disk. This not only occupies the space on the side of the hard disk, but also causes the path of the light guide column to be longer, resulting in relatively more light loss. The light guide column of this embodiment is arranged at the first end of the hard disk and extends from the first wall of the bracket body to the first opening. Not only does it not occupy the space on the side of the hard disk, but also shortens the light guide path of the light guide column, which can reduce light loss.

[0061] In an optional embodiment, a mounting hole is formed on the first wall, and the mounting hole includes a first hole segment and a second hole segment connected in sequence in a direction away from the hard disk, the inner diameter of the first hole segment is larger than the inner diameter of the second hole segment, and an abutment annular surface is formed at the connection between the first hole segment and the second hole segment, and the light guide column includes a light guide column body and a limiting boss formed at the end of the light guide column body, and the light guide column body is suitable for passing through the first hole segment and the second hole segment in sequence, and the limiting boss is clamped between the abutment annular surface and the hard disk.

[0062] Beneficial effect: During the assembly of the hard disk bracket, the operator can first pass the main body of the light guide column through the first hole section and the second hole section in sequence, and then fix the hard disk bracket to the first end of the hard disk. The limiting boss of the light guide column can be clamped between the abutting annular surface and the hard disk, thereby completing the limiting of the light guide column, so that the light guide column does not require additional structural fixings to be fixed.

[0063] In an optional embodiment, the inner diameter of the second hole segment gradually decreases in a direction away from the hard disk, and a guiding inclined surface matching the inner peripheral wall of the second hole segment is formed on the limiting boss.

[0064] Beneficial effect: The guide surface cooperates with the guide inclined surface, which can not only facilitate the light guide column body to flexibly pass through the installation hole, but also can realize the complete fixation of the light guide column in combination with the hard disk.

[0065] In an optional embodiment, a reinforcing rib extending in a direction away from the hard disk is formed in the bracket body, and a through hole extending in a direction away from the hard disk is formed on the reinforcing rib, the through hole is connected to the mounting hole, and the light guide column body is suitable for passing through the mounting hole and the through hole in sequence.

[0066] Beneficial effect: The reinforcing ribs can not only increase the strength of the bracket body, but also limit the position of the light guide column body.

[0067] In a second aspect, the present application further provides a hard disk module, comprising:

[0068] harddisk;

[0069] The hard disk bracket provided in the first aspect of the present application is connected to the first end of the hard disk.

[0070] Beneficial Effects: The hard disk module of the second aspect of the present application includes or utilizes the hard disk bracket of the first aspect of the present application, thereby achieving the beneficial effects of ensuring that the connection between the hard disk bracket and the hard disk, as well as the connection between the hard disk bracket and the slot of the chassis, can be completed at the first end of the hard disk. Furthermore, because the hard disk bracket is fixed to the first end of the hard disk, when the hard disk is inserted into the slot, the hard disk bracket can be partially located outside the slot, thereby reducing the space occupied by the hard disk bracket along the length of the hard disk.

[0071] The hard drive tray of the hard drive module in the embodiment of the present application only needs to occupy space along the length of the hard drive and does not need to extend between the hard drive and the slot in the chassis. This avoids the hard drive tray occupying space along the width or thickness of the hard drive, which could limit the usable space in the width or thickness direction of the hard drive or restrict the space for device layout on the hard drive backplane. This can solve the problem in the related art where the hard drive tray limits the usable space along the width of the hard drive, reducing the number of hard drives that can be supported by the server.

[0072] In a third aspect, the present application further provides a server, including:

[0073] A chassis, wherein a slot is formed in the chassis; a first connector is provided in the slot;

[0074] The hard disk module provided in the second aspect of the present application includes a hard disk, and a second connector is provided at the second end of the hard disk, and the second connector is suitable for plugging with the first connector.

[0075] Beneficial Effects: The server of the third aspect of the present application includes or utilizes the hard disk module of the second aspect of the present application, thereby achieving the beneficial effects of ensuring that the connection between the hard disk bracket and the hard disk, as well as the connection between the hard disk bracket and the slot of the chassis, can be completed at the first end of the hard disk. Furthermore, because the hard disk bracket is fixed to the first end of the hard disk, when the hard disk is inserted into the slot, the hard disk bracket can be partially located outside the slot, thereby reducing the space occupied by the hard disk bracket along the length of the hard disk.

[0076] The server hard drive bracket of the embodiment of the present application only needs to occupy space in the length direction of the hard drive and does not need to extend between the hard drive and the slot of the chassis, thereby increasing the width or thickness of the hard drive. This avoids the hard drive bracket occupying space in the width or thickness direction of the hard drive, thereby limiting the usable space in the width or thickness direction of the hard drive or restricting the space for device layout on the hard drive backplane. This can solve the problem in the related art where the hard drive bracket limits the usable space in the width direction of the hard drive, thereby reducing the number of hard drives that the server can support.

[0098] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0099] Currently, the most common hard drives in the server field are 3.5-inch and 2.5-inch hard drives. With the popularization of PCIe (Peripheral component interconnect express, a high-speed serial computer expansion bus standard) 5.0, a new hard drive, the E3 hard drive, has begun to appear on the market. E3 hard drives are available in different thicknesses to meet different space requirements. To secure the E3 hard drive, a hard drive bracket is required. Some areas with higher space requirements have high requirements not only for the size of the hard drive, but also for the size of the hard drive bracket. It is necessary to minimize the additional space occupied by the hard drive bracket in terms of thickness, width, and depth, while also reducing the number of structural components as much as possible to optimize cost.

[0100] To secure E3 hard drives, such as the 7.6mm-thick E3.S hard drives currently on the market, existing solutions include using drive brackets on all sides. This solution requires additional space on the left and right sides, limiting the available space along the drive's width. The rear end of the bracket also restricts component layout space on the drive backplane. Furthermore, the drive bracket's thickness extends beyond the drive, increasing the space occupied by the drive along its thickness. This not only limits the available space within the drive enclosure but also reduces the number of drives that can be supported by the server.

[0101] The following describes an embodiment of the present application in conjunction with Figures 1 to 19.

[0102] According to an embodiment of the present application, in one aspect, a hard disk tray is provided, comprising a tray body 1, a first connecting structure, and a second connecting structure. The tray body 1 is adapted to be positioned at the first end of a hard disk 7. The hard disk 7 is adapted to be inserted into a slot 6 of a computer chassis, with the first end of the hard disk 7 positioned at the notch of the slot 6. The first connecting structure detachably connects the tray body 1 to the first end of the hard disk 7. The second connecting structure detachably connects the tray body 1 to the notch of the slot 6.

[0103] As shown in FIG1 , the bracket body 1 of the hard disk bracket of the present application is connected to the first end of the hard disk 7 via a first connecting structure, and is detachably connected to the notch of the chassis slot 6 via a second connecting structure, thereby ensuring that the connection between the hard disk bracket and the hard disk 7, as well as the connection between the hard disk bracket and the chassis slot 6, can be completed at the first end of the hard disk 7. Furthermore, because the hard disk bracket is fixed to the first end of the hard disk 7, when the hard disk 7 is inserted into the slot 6, the hard disk bracket can be partially located outside the slot 6, thereby reducing the space occupied by the hard disk bracket along the length direction of the hard disk 7.

[0104] The hard disk bracket of the embodiment of the present application only needs to occupy the space in the length direction of the hard disk 7 and does not need to extend between the hard disk 7 and the slot 6 of the chassis, thereby increasing the width or thickness of the hard disk 7. This avoids the hard disk bracket occupying the space in the width or thickness direction of the hard disk 7, resulting in a limited range of space usage in the width or thickness direction of the hard disk 7, or restricting the space for device layout on the backplane of the hard disk 7. The hard disk bracket of the present application can solve the problem in the related art that the hard disk bracket limits the range of space usage in the width direction of the hard disk 7, thereby reducing the number of hard disks 7 that can be supported by the server, and helps to increase the number of hard disks 7 that can be supported by the server.

[0105] In one embodiment, the positive projection of the bracket body 1 toward the hard disk 7 is located within the end face of the first end of the hard disk 7, which can prevent the bracket body 1 from increasing the thickness or width of the hard disk 7, resulting in limited space usage in the width or thickness direction of the hard disk 7, or limiting the device layout space on the backplane of the hard disk 7.

[0106] In one embodiment, as shown in FIG17 , the bracket body 1 includes a first wall 101. The first wall 101 is adapted to abut against the first end of the hard disk 7. As shown in FIG3 , a first opening 102 is provided on a side of the bracket body 1 away from the hard disk 7. The first connection structure includes a first connection hole and a fastener 203. The first connection hole is formed on the first wall 101. The fastener 203 is adapted to sequentially pass through the first opening 102 and the first connection hole and connect to the hard disk 7. Through such an arrangement, the bracket body 1 can be reliably fixed to the first end of the hard disk 7 while occupying a small space.

[0107] The fastener 203 is preferably, but not limited to, a bolt or a rivet, and is preferably a bolt that can be repeatedly disassembled and assembled.

[0108] In one embodiment, as shown in Figures 7 and 8, the second connection structure includes a lever structure 301. The lever structure 301 includes a hinged end 3011 and an operating end 3012. The hinged end 3011 is hingedly connected to a first end of the bracket body 1 along the length direction and is disposed within the first opening 102. The operating end 3012 is detachably connected to a second end of the bracket body 1 along the length direction. The lever structure 301 is adapted to assist in plugging or unplugging the second connector 701 from the first connector 601.

[0109] The operator can first separate the operating end 3012 of the lever structure 301 from the second end of the bracket body 1 along the length direction, and then hold the operating end 3012 of the lever structure 301 and apply force through its operating end 3012 to assist in plugging or unplugging the hard disk 7 and the slot 6, which can reduce the plugging and unplugging force required for disassembling the hard disk 7, making the disassembly and assembly process more labor-saving and reducing the labor intensity of the operator.

[0110] In one embodiment, the hinged end 3011 is detachably hinged to the first end of the bracket body 1 along the length direction.

[0111] In the related art, the part of the hard disk bracket located at the first end of the hard disk 7 is generally used to set a connecting structure connected to the slot of the chassis. There is no space to accommodate the connecting structure connecting the hard disk 7 and the hard disk bracket, resulting in the connecting structure for connecting to the hard disk 7 and the hard disk bracket being generally set on the side of the hard disk 7. The hard disk bracket needs to be set to partially extend between the slot 6 of the chassis and the hard disk 7, occupying the space on both sides of the hard disk 7 along the width direction.

[0112] The hard disk bracket of this embodiment sets the hinged end 3011 in the first opening 102 and is detachably connected to the first end of the bracket body 1 along the length direction. When the hard disk bracket needs to be installed on the hard disk 7, the operator can first pass the fastener 203 through the first opening 102 and the first connecting hole in sequence, connect the hard disk bracket to the first end of the hard disk 7, and then connect the hinged end 3011 to the first opening 102.

[0113] When the hard disk 7 needs to be repaired or replaced, the operator can first separate the hinged end 3011 of the lever structure 301 from the bracket body 1, and then remove the fastener 203 through the first opening 102. This arrangement ensures that the connection between the hard disk bracket and the hard disk 7, as well as the connection between the hard disk bracket and the slot 6 of the chassis, can be completed at the first end of the hard disk 7, and the hard disk bracket can be removed from the hard disk bracket so that the hard disk bracket can be reused.

[0114] In one embodiment, the bracket body 1 further includes a second wall 103 and a third wall 104. The second wall 103 and the third wall 104 are respectively connected to both ends of the first wall 101 along the thickness direction of the bracket body 1. The second wall 103 and the third wall 104 are respectively provided with a second connecting hole 105 and a threaded hole 106. The second connecting structure further includes a first hinge shaft 3016 (see Figures 9 and 10). The first hinge shaft 3016 passes through the second connecting hole 105 and the hinge end 3011, and is threadedly connected to the threaded hole 106.

[0115] Through such an arrangement, when the lever structure 301 needs to be installed on the bracket body 1, the operator can first place the hinge part 3031 into the first opening 102, then pass the first hinge shaft 3016 through the second connecting hole 105 and the hinge end 3011 in sequence, and finally rotate the first hinge shaft 3016 to thread the first hinge shaft 3016 into the threaded hole 106 to complete the assembly of the lever structure 301.

[0116] When the lever structure 301 needs to be removed from the bracket body 1, the operator can reversely rotate the first hinge shaft 3016 to release the threaded connection between the first hinge shaft 3016 and the threaded hole 106, and then withdraw the first hinge shaft 3016. Since the threaded hole 106 is provided on the third wall 104, it is no longer necessary to use a nut to limit the first hinge shaft 3016, thereby avoiding the need to increase the thickness of the bracket body 1 due to the use of a nut.

[0117] As a convertible embodiment, a threaded hole 106 is provided on the second wall 103 , and a second connecting hole 105 is provided on the third wall 104 .

[0118] As another convertible embodiment, connecting holes are respectively provided on the second wall 103 and the third wall 104, and the first hinge shaft 3016 passes through the connecting hole on the second wall 103, the hinge end 3011 and the connecting hole on the third wall 104 in sequence, and is finally threadedly connected with the nut.

[0119] In one embodiment, the lever structure 301 further includes a first abutting protrusion 3013. The first abutting protrusion 3013 is formed at the hinge end 3011 of the lever structure 301. An abutting groove 602 is formed on the wall of the slot 6. When the operating end 3012 is connected to the second end of the bracket body 1, the first abutting protrusion 3013 abuts against the wall of the abutting groove 602. When the operating end 3012 moves in a direction away from the hard disk 7, the first abutting protrusion 3013 is adapted to disengage from the abutting groove 602.

[0120] With this arrangement, when the hard disk 7 needs to be inserted into the slot 6, the operator can first place the hard disk 7 in the slot 6, and then drive the operating end 3012 to rotate in a direction close to the hard disk 7, thereby facilitating the connection between the hard disk 7 and the slot 6 through the cooperation between the second abutting protrusion 3014 and the abutting groove 602. After the operating end 3012 is connected to the second end of the bracket body 1 along the longitudinal direction, the first abutting protrusion 3013 can be constrained in the abutting groove 602, thereby preventing the hard disk 7 from being dislodged from the slot 6 due to external force or misoperation.

[0121] As shown in Figures 5 and 6, when the hard disk 7 needs to be pulled out of the slot 6, the operator can release the connection between the operating end 3012 and the second end of the bracket body 1 along the length direction, rotate the operating end 3012 in the direction away from the outer shell, and the first abutment protrusion 3013 can disengage from the abutment groove 602 to allow the hard disk 7 to be pulled out of the slot 6.

[0122] Preferably, a label groove is formed on the lever structure 301, and the label groove is used for sticking a label.

[0123] In one embodiment, the second connection structure further includes a second abutting protrusion 3014 connected to the hinge end 3011 , and the second abutting protrusion 3014 abuts against a notch of the slot 6 .

[0124] When the operator applies force to the operating end 3012 of the lever structure 301, forcing the operating end 3012 to rotate in a direction away from the hard disk 7, the hinged end 3011 of the lever structure 301 can rotate in the opposite direction, so that the second abutting protrusion 3014 applies pressure to the notch of the slot 6, so that the hard disk 7 can be disengaged from the slot 6 under the reaction force at the notch.

[0125] Preferably, a beveled abutment surface is formed at the first end of the bracket body 1 along its length. When the operating end 3012 moves away from the hard disk 7, the second abutting protrusion 3014 is adapted to sequentially abut against the notch of the slot 6 and the beveled abutment surface. With this arrangement, when the lever structure 301 is opened to its maximum angle, the beveled abutment surface can abut against the second abutting protrusion 3014, thereby limiting the position of the lever structure 301.

[0126] In one embodiment, the second connection structure further includes a first elastic member 302, a lock 303, and a second elastic member 304. The first elastic member 302 is supported between the lever structure 301 and the bracket body 1 and is adapted to drive the lever structure 301 to rotate away from the hard disk 7. The lock 303 is movably connected to the second end of the bracket body 1 and has a locked position in which it is locked to the operating end 3012 of the lever structure 301 and an unlocked position in which it is separated from the operating end 3012. The second elastic member 304 is supported between the lock 303 and the bracket body 1 and is adapted to be in the locked position with the support of the second elastic member 304.

[0127] Through such a setting, when the hard disk 7 needs to be installed in the slot 6, the operator can drive the operating end 3012 to move in the direction close to the hard disk 7 and compress the first elastic member 302. The lock 303 can be locked and connected with the operating end 3012 under the support of the second elastic member 304. At this time, the first abutting protrusion 3013 can be constrained in the abutting groove 602, thereby preventing the hard disk 7 from escaping from the slot 6 under the action of external force or due to misoperation.

[0128] When it is necessary to remove the hard disk 7 from the slot 6, the operator can apply force to the lock catch 303 and compress the second elastic member 304 to switch the lock catch 303 to an unlocked position separated from the operating end 3012, thereby releasing the connection between the operating end 3012 and the second end along the length of the bracket body 1. Under the elastic force of the first elastic member 302, the operating end 3012 can rotate in a direction away from the housing, allowing the first abutting protrusion 3013 to disengage from the abutting groove 602. At the same time, the second abutting protrusion 3014 applies pressure to the notch of the slot 6, causing the hard disk 7 to be removed from the slot 6 due to the reaction force of the notch.

[0129] In one embodiment, as shown in Figures 14 and 15 , a first abutment portion 3017 is formed on the bracket body 1. The lever structure 301 also includes a first torsion spring slot 3015. The first torsion spring slot 3015 is formed on the hinge end 3011 of the lever structure 301. The first elastic member 302 is a first torsion spring. The first torsion spring is mounted on the first hinge shaft 3016 and inserted into the first torsion spring slot 3015. The two ends of the first torsion spring respectively abut against the groove wall of the first torsion spring slot 3015 and the first abutment portion 3017. With this arrangement, when the operating end 3012 is locked and connected to the lock catch 303, the groove wall of the first torsion spring slot 3015 can compress the two ends of the first torsion spring. When the lock catch 303 is switched to the unlocked position, the first torsion spring can return to its original state due to its own elastic restoring force, and drive the operating end 3012 to rotate in a direction away from the hard disk 7. As a convertible embodiment, the first elastic member 302 is a spring, and is supported between the hinge end 3011 of the lever structure 301 and the bracket body 1 .

[0130] In one embodiment, a second abutment portion 3019 is formed at the second end of the bracket body 1. As shown in Figures 11 and 12, the lock 303 includes a hinge portion 3031, a second hinge axis 3032, a third abutment protrusion 3036, an operating portion 3033, and a second torsion spring slot 3035. The hinge portion 3031 is hinged to the second end of the bracket body 1. The second hinge axis 3032 passes through the bracket body 1 and the hinge portion 3031. The third abutment protrusion 3036 is connected to the hinge portion 3031 and is suitable for abutting against the operating end 3012 of the lever structure 301. The operating portion 3033 is connected to the hinge portion 3031. The second torsion spring slot 3035 is formed on the hinge portion 3031. The second elastic member 304 is a second torsion spring, which is sleeved on the second hinge shaft 3032 and inserted into the second torsion spring slot 3035 . Two ends of the second torsion spring abut against the slot wall of the second torsion spring slot 3035 and the second abutting portion 3019 respectively.

[0131] With this arrangement, when the operating end 3012 is moved toward the hard disk 7 by an external force, the operating end 3012 first interferes with the first abutting protrusion 3013, causing the first abutting protrusion 3013 to rotate toward the hard disk 7, allowing the operating end 3012 to enter between the first abutting protrusion 3013 and the hard disk 7. Subsequently, the lock catch 303, supported by the second torsion spring, is locked in the locked position, causing the third abutting protrusion 3036 to abut against the operating end 3012, preventing the operating end 3012 from falling out of the first opening 102.

[0132] When it is necessary to remove the hard disk 7 from the slot 6, the operator can apply force to the operating portion 3033 and compress the second torsion spring, causing the lock 303 to rotate in the opposite direction and move to the unlocked position, allowing the operating end to rotate away from the hard disk 7 under the elastic force of the first torsion spring. Preferably, a fixing groove 3018 is formed on the operating end 3012 of the lever structure 301 for engaging and fixing with the third abutting protrusion 3036 of the lock 303.

[0133] In one embodiment, the first connection hole includes a second hole 202. The second hole 202 is disposed at the second end of the bracket body 1 along the length direction. The hard disk bracket further includes a cover plate 4. The cover plate 4 is removably disposed over the first opening 102 at the second end of the bracket body 1 along the length direction, and is adapted to conceal the fastener 203. The cover plate 4 can be disposed over the first opening 102 corresponding to the second hole 202 to prevent the fastener 203 from being exposed, thereby enhancing the aesthetics of the hard disk 7.

[0134] In one embodiment, the cover plate 4 is inserted into the bracket body 1 through the first opening 102 at the second end of the bracket body 1 along the length direction. The bracket body 1 can limit the cover plate 4 by accommodating it to avoid the cover plate 4 occupying additional space.

[0135] In one embodiment, as shown in Figure 13, the cover plate 4 includes a shielding portion 401 and a cantilever 402. One end of the cantilever 402 is connected to the shielding portion 401, and the other end is suspended along the plug-in direction of the cover plate 4 and the first opening 102. A limiting protrusion 403 is formed on the cantilever 402. A limiting groove 109 suitable for accommodating the limiting protrusion 403 is formed on the inner wall of the first opening 102. When the cover plate 4 is inserted into the first opening 102, the limiting protrusion 403 can first abut against the inner wall of the first opening 102 and compress the cantilever 402. When the cover plate 4 is installed in place, the limiting protrusion 403 can enter the limiting groove 109 and limit the cover plate 4 in the first opening. The shielding portion 401 can block the outside of the first opening 102 to prevent the fastener 203 from being exposed, which helps to improve the aesthetics of the hard disk 7.

[0136] In one embodiment, a stopper 1071 is formed on the inner wall of the first opening 102. The stopper 1071 is adapted to abut against the insertion end of the cover plate 4. When the cover plate 4 is installed, the stopper 1071 can abut against the insertion end of the cover plate 4 and prevent the cover plate 4 from further entering the first opening 102, thereby making it difficult for the operator to remove the cover plate 4 from the first opening 102. The stopper 1071 can optionally be formed on the inner wall of the first opening 102. Preferably, in this embodiment, the stopper 1071 is formed on the side wall of the bracket body 1 away from the first end.

[0137] In one embodiment, the hard disk tray further includes a light guide 5, which is disposed within the tray body 1 and extends from the first wall 101 of the tray body 1 to the first opening 102. In related art, a hard disk tray generally extends the side of the hard disk 7, and the light guide 5 is located between the side of the hard disk 7 and the hard disk tray, and extends from the second end of the hard disk 7 to the first end of the hard disk 7. This not only occupies space on the side of the hard disk 7, but also causes the path of the light guide 5 to be longer, resulting in relatively more light loss. In this embodiment, the light guide 5 is disposed at the first end of the hard disk 7 and extends from the first wall 101 of the tray body 1 to the first opening 102. This not only does not occupy space on the side of the hard disk 7, but also shortens the light guide path of the light guide 5, thereby reducing light loss.

[0138] In one embodiment, as shown in Figures 16 and 17, a mounting hole 108 is formed on the first wall 101. The mounting hole 108 includes a first hole segment 1081 and a second hole segment 1082 connected in sequence in a direction away from the hard disk 7. The inner diameter of the first hole segment 1081 is larger than the inner diameter of the second hole segment 1082, and an abutting annular surface is formed at the connection between the first hole segment 1081 and the second hole segment 1082. As shown in Figure 19, the light guide column 5 includes a light guide column body 501 and a limiting boss 502 formed at the end of the light guide column body 501. The light guide column body 501 is suitable for passing through the first hole segment 1081 and the second hole segment 1082 in sequence. The limiting boss 502 is clamped between the abutting annular surface and the hard disk 7. During the process of assembling the hard disk bracket, the operator can first pass the light guide column body 501 through the first hole section 1081 and the second hole section 1082 in sequence, and then fix the hard disk bracket to the first end of the hard disk 7. The limiting boss 502 of the light guide column 5 can be clamped between the abutting annular surface and the hard disk 7, thereby completing the limiting of the light guide column 5, so that the light guide column 5 is fixed without the need for additional structural fixings.

[0139] In one embodiment, as shown in FIG16 , the inner diameter of the second hole section 1082 gradually decreases in a direction away from the hard disk 7. A guide slope 5021 is formed on the limiting boss 502 to match the inner circumferential wall of the second hole section 1082. The inner circumference of the second hole section 1082 forms a guide surface, which cooperates with the guide slope 5021 to facilitate the flexible passage of the light guide column body 501 through the mounting hole 108 while fully securing the light guide column 5 in conjunction with the hard disk 7.

[0140] In one embodiment, as shown in FIG18 , a reinforcing rib 110 is further formed in the bracket body 1 and extends in a direction away from the hard disk 7. A through hole 111 is formed in the reinforcing rib 110 and extends in a direction away from the hard disk 7. The through hole 111 is connected to the mounting hole 108, and the light guide column body 501 is adapted to sequentially pass through the mounting hole 108 and the through hole 111. By so configuring, the reinforcing rib 110 can both increase the strength of the bracket body 1 and limit the position of the light guide column body 501.

[0141] According to an embodiment of the present application, in a second aspect, a hard disk module is further provided, comprising a hard disk 7 and a hard disk bracket, wherein the hard disk bracket is connected to a first end of the hard disk 7 .

[0142] The hard disk module of the second aspect of the present application includes or utilizes the hard disk bracket of the first aspect of the present application, thereby achieving its beneficial effect, namely, ensuring that the connection between the hard disk bracket and the hard disk 7, as well as the connection between the hard disk bracket and the slot 6 of the chassis, can be completed at the first end of the hard disk 7. Furthermore, because the hard disk bracket is fixed at the first end of the hard disk 7, when the hard disk 7 is inserted into the slot 6, the hard disk bracket can be partially located outside the slot 6, thereby reducing the space occupied by the hard disk bracket along the length direction of the hard disk 7.

[0143] The hard drive bracket of the hard drive module of the present embodiment only needs to occupy space in the length direction of the hard drive 7 and does not need to extend between the hard drive 7 and the slot 6 of the chassis. This avoids the hard drive bracket occupying space in the width or thickness direction of the hard drive 7, which would limit the usable space in the width or thickness direction of the hard drive 7 or restrict the space for device layout on the backplane of the hard drive 7. This solves the problem in the related art that the hard drive bracket limits the usable space in the width direction of the hard drive 7, thereby reducing the number of hard drives 7 that the server can support.

[0144] Next, the installation method of the hard disk module of the embodiment of the present application is described:

[0145] First, the light guide column body 501 of the light guide column 5 is sequentially passed through the first hole section 1081 and the second hole section 1082 of the installation hole 108 and the through hole 111 until the light guide column body 501 is completely installed in the through hole 111 .

[0146] Then, install the second torsion spring into the second torsion spring slot 3035 of the lock catch 303. Place the lock catch 303 into the first opening 102 at the second end of the bracket body 1 along its length, so that the two ends of the second torsion spring respectively abut against the slot wall of the second torsion spring slot 3035 and the second abutment portion 3019. Pass the second rotating shaft through the bracket body 1, lock catch 303, and torsion spring, and secure it to the bracket body 1 by riveting.

[0147] Then use the fastener 203 to pass through the first opening 102 and the first connecting hole to fix the bracket body 1 at the first end of the hard disk 7. At this time, the two indicator lights at the first end of the hard disk 7 correspond to the limiting boss 502 of the light guide column 5, and the light guide column 5 can guide the light emitted by the indicator lights.

[0148] Then install the first torsion spring into the first torsion spring groove 3015, install the hinge end 3011 into the first opening 102 at the first end of the bracket body 1 along the length direction, and pass the first hinge axis 3016 through the second connecting hole 105, the hinge end 3011 and the first torsion spring in sequence, and threadedly connect it to the threaded hole 106.

[0149] Finally, the cover plate 4 is inserted into the first opening 102 at the second end of the bracket body 1 along the length direction, so that the limiting protrusion 403 enters the limiting groove 109, and the installation is completed.

[0150] According to an embodiment of the present application, in a third aspect, a server is further provided, comprising a chassis and a hard disk module. A slot 6 is formed in the chassis; a first connector 601 is disposed in slot 6. The hard disk module is the hard disk bracket provided in the second aspect of the present application. The hard disk module includes a hard disk 7. A second connector 701 is disposed at a second end of the hard disk 7, and the second connector 701 is adapted to be plugged into the first connector 601. Specifically, a hard disk 7 frame is disposed on the chassis, and a slot 6 is formed in the hard disk 7 frame.

[0151] The server of the third aspect of the present application includes or uses the hard disk module of the second aspect of the present application, thereby achieving its beneficial effect, namely, ensuring that the connection between the hard disk bracket and the hard disk 7, and the connection between the hard disk bracket and the slot 6 of the chassis can both be completed at the first end of the hard disk 7. Moreover, because the hard disk bracket is fixed at the first end of the hard disk 7, when the hard disk 7 is inserted into the slot 6, the hard disk bracket can be partially located outside the slot 6, thereby reducing the space occupied by the hard disk bracket along the length direction of the hard disk 7.

[0152] The hard disk tray of the server in the embodiment of the present application only needs to occupy space in the length direction of the hard disk 7 and does not need to extend between the hard disk 7 and the slot 6 of the chassis, thereby increasing the width or thickness of the hard disk 7. This avoids the hard disk tray occupying space in the width or thickness direction of the hard disk 7, which limits the usable space in the width or thickness direction of the hard disk 7, or restricts the space for device layout on the backplane of the hard disk 7. This can solve the problem in the related art that the hard disk tray limits the usable space in the width direction of the hard disk 7, thereby reducing the number of hard disks 7 that the server can support.
