Description

Technical Field

[0001] This invention relates to the field of server storage device technology, and more specifically, to a multi-specification hard drive direct-plug module and server. Background Technology

[0002] As the demand for server storage capacity and configuration flexibility increases, servers typically require the installation of multiple hard drives. Hard drives come in various sizes, and the length, width, and thickness of hard drives of different sizes may vary.

[0003] Existing servers typically require a separate hard drive enclosure for each hard drive, compatible with its specifications. During installation, the hard drive is first secured to the enclosure, and then both the hard drive and enclosure are inserted into the corresponding slot in the server. This method increases the number of steps involved in installing and removing the hard drive enclosure, as well as the quantity of materials required. When a server needs to be compatible with multiple hard drive sizes, separate hard drive enclosures of different sizes must be prepared and managed, which can easily lead to mismatches or loss, causing inconvenience for server assembly, expansion, and maintenance.

[0004] If the independent hard drive frame is removed, due to the different dimensions of hard drives of different sizes, it is difficult for the hard drives to be stably supported and positioned within the slot, and it is also difficult to share a single direct-insertion slot. During the hard drive insertion process, its connection interface may not be accurately aligned with the connector inside the server; after insertion, there may be shaking, disengagement, or loosening of the connection.

[0005] Therefore, it is urgent to solve the problem that hard drives of different specifications rely on their own independent hard drive frames, so that at least two different types of hard drives can share the same direct-insertion slot and reliably complete positioning, connection and retention. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a multi-specification hard drive direct insertion module, which enables at least two types of hard drives to share the same direct insertion slot and reliably complete positioning, connection and retention.

[0007] Another objective of this invention is to provide a server that includes the above-mentioned multi-specification hard drive direct-plug modules, so as to improve the convenience of hard drive configuration and maintenance.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A multi-size hard drive through-hole module includes: a module frame for mounting in a chassis and forming a guide channel extending along the insertion direction F of the hard drive, the guide channel having an insertion port end and a connection end, and for accommodating at least two different sizes of hard drives; a connector disposed at the connection end for plugging into the connection interface of the hard drive; a positioning structure disposed in the guide channel, including a supporting reference portion for supporting the hard drive housing and a lateral reference portion for one side of the hard drive housing to abut against; a size adaptation component disposed in the guide channel, the size adaptation component including a lateral pressing member disposed opposite to the lateral reference portion, the lateral pressing member being movable relative to the module frame for abutting against the other side of the hard drive housing, and correspondingly making room when different sizes of hard drives are inserted, so as to press the hard drive towards the lateral reference portion and align the connection interface of the hard drive with the connector; and a locking component disposed in the module frame, which can engage with the locking part of the hard drive when the connection interface of the hard drive is in the plugged-in state with the connector, so as to restrict the movement of the hard drive in a direction opposite to the insertion direction F.

[0009] Preferably, there are at least two supporting reference parts, which are spaced apart along the width direction of the guide channel. Each supporting reference part is a strip extending along the insertion direction F and has a supporting surface for supporting the bottom surface of the hard disk housing. The lateral reference part is a fixed reference guide rail extending along the insertion direction F and is used for one side of the hard disk housing to abut against.

[0010] Preferably, there are at least two lateral holding members, which are spaced apart along the insertion direction F. Each lateral holding member is movable independently relative to the module frame and is used to abut against the other side of the hard disk housing under an elastic force toward the lateral reference portion.

[0011] Preferably, each of the lateral holding members includes an adapter rocker arm, a first rotating shaft, a lateral roller, and a first torsion spring. One end of the adapter rocker arm is rotatably connected to the module frame via the first rotating shaft. The lateral roller is rotatably disposed at the other end of the adapter rocker arm and is used to abut against the hard disk housing. The first torsion spring is sleeved on the first rotating shaft and acts on the adapter rocker arm and the module frame respectively to drive the lateral roller to move towards the lateral reference portion. The module frame is provided with a limiting block that cooperates with the adapter rocker arm. The limiting block is used to limit the rotational position of the adapter rocker arm under the action of the first torsion spring.

[0012] Preferably, the specification adapter component further includes an upper pressing member disposed opposite to the support reference portion. At least a portion of the upper pressing member is movable relative to the module frame in a direction close to or away from the support reference portion, and is used to abut against the side of the hard disk housing away from the support reference portion under an elastic force toward the support reference portion, so as to make corresponding clearance when hard disks of different thicknesses are inserted, and to press the hard disk toward the support reference portion.

[0013] Preferably, the upper holding member includes an upper rocker arm, a second rotating shaft, an upper roller, and a second torsion spring. One end of the upper rocker arm is rotatably connected to the module frame via the second rotating shaft. The upper roller is rotatably disposed at the other end of the upper rocker arm and is used to abut against the hard disk housing. The second torsion spring is sleeved on the second rotating shaft and acts on the upper rocker arm and the module frame respectively to drive the upper roller to move toward the support reference part.

[0014] Preferably, the module frame has a terminal guide at the connection end, the terminal guide having a guide surface that gradually inclines towards the inside of the guide channel along the insertion direction F towards the connection end; the connector is a hot-plug connector and is mounted on a floating connector seat, the floating connector seat being buoyantly disposed at the connection end by means of an elastic sleeve, the elastic sleeve being capable of elastic deformation in a plane perpendicular to the insertion direction F, so that the connector can float in the plane.

[0015] Preferably, the locking assembly includes a locking pin and a locking spring. The locking pin is movably disposed on the module frame and can extend into or retract from the guide channel. The locking spring applies a force to the locking pin toward the guide channel. The locking mating part includes a side mounting hole on the side of the hard disk housing. When the connection interface of the hard disk is in the plugged-in state with the connector, the locking pin can extend into the side mounting hole under the action of the locking spring. The end of the locking pin extending into the guide channel has a guide slope toward the insertion port end and a stop surface toward the connection end.

[0016] Preferably, the locking pins are at least two and spaced apart along the insertion direction F. The locking assembly further includes a common unlocking plate, an unlocking transmission rod, and an unlocking button. The locking springs are arranged in a one-to-one correspondence with the locking pins, each locking spring acting on the corresponding locking pin and the module frame to independently apply a force toward the guide channel to the corresponding locking pin. The common unlocking plate is movably disposed on the module frame along the direction approaching or away from the guide channel. Each locking pin forms a traction connection with the common unlocking plate and can move independently relative to the common unlocking plate along the direction of insertion or withdrawal from the guide channel. The unlocking transmission rod moves along the insertion direction... The direction F is movably disposed on the module frame, the unlock button is disposed at the insertion port end and connected to the unlock transmission rod; the common unlock plate is provided with a cam groove inclined relative to the insertion direction F, and the unlock transmission rod is provided with a follower part that cooperates with the cam groove, so as to drive the common unlock plate away from the guide channel when the unlock transmission rod moves, and the common unlock plate pulls each of the locking pins to overcome the force of the corresponding locking springs and move synchronously in the direction of exiting the guide channel; after the common unlock plate releases the pull on each of the locking pins, each of the locking pins moves in the direction of extending into the guide channel under the action of the corresponding locking springs.

[0017] Preferably, the assembly further includes an ejection component, which comprises an ejection plate, a guide rod, and an ejection spring. The guide rod is disposed on the module frame along the insertion direction F. The ejection plate is slidably disposed on the guide rod and near the connection end. The ejection spring is disposed between the ejection plate and the module frame. The ejection plate includes two abutting portions spaced apart along the thickness direction of the hard disk. A connector clearance area is formed between the two abutting portions, and at least one of the two abutting portions is used to abut against the end face of the hard disk housing facing the connection end. When the hard disk moves toward the connection end, it pushes the ejection plate and causes the ejection spring to store energy. The ejection spring is used to drive the ejection plate to eject the hard disk toward the insertion port end after the locking assembly separates from the locking engagement portion.

[0018] Preferably, the ejection plate has a travel groove extending along the insertion direction F, and the module frame has a first travel stop, a second travel stop, and a travel selector. The first travel stop and the second travel stop are spaced apart along the insertion direction F. The travel selector can switch between a first selection state and a second selection state. In the first selection state, only the first travel stop engages with the travel groove stop, and in the second selection state, only the second travel stop engages with the travel groove stop, so as to respectively limit the ejection travel corresponding to hard drives of different specifications.

[0019] Preferably, the system further includes a support slide, which is slidably disposed in the guide channel along the insertion direction F. The hard disk is detachably supported on the support slide and is limited to cooperate with the support slide along the insertion direction F. The support reference portion is disposed on the support slide. An operating portion is provided at one end of the support slide near the insertion port. The operating portion is used to drive the support slide and the hard disk to move along the insertion direction F, so that the connection interface is inserted into or separated from the connector. One of the module frame and the support slide is provided with an anti-detachment groove extending along the insertion direction F, and the other is provided with an anti-detachment pin extending into the anti-detachment groove. The anti-detachment pin can move along the anti-detachment groove and cooperate with the end stop of the anti-detachment groove to prevent the support slide from disengaging from the guide channel.

[0020] Preferably, it further includes an in-situ detection component, which is configured correspondingly to the guide channel and is triggered by the hard disk when the hard disk reaches a predetermined insertion depth to output an in-situ signal of the hard disk.

[0021] A server includes a chassis and at least one of the above-mentioned multi-specification hard drive through-hole modules, the module frame being mounted on the chassis, the insertion port end corresponding to the hard drive insertion port of the chassis, and the connector being mounted on the chassis and located at the connection end.

[0022] Preferably, there are multiple multi-specification hard drive through-hole modules, and each multi-specification hard drive through-hole module is provided with an presence detection component for outputting the presence signal of the corresponding hard drive; the server also includes a control unit and multiple display units disposed outside the chassis, each display unit corresponding to each multi-specification hard drive through-hole module, and the control unit is used to control the corresponding display unit to indicate whether the corresponding hard drive is present according to the presence signal output by each presence detection component.

[0023] In the multi-specification hard drive through-hole module provided by this invention, the guide channel provides a common insertion path for hard drives of different specifications. The supporting reference part supports the hard drive from one side to determine its position in the corresponding direction, while the lateral reference part establishes a common lateral positioning reference from the other side of the hard drive. The lateral pressing member is located on the side opposite to the lateral reference part and can move relative to the module frame according to the specifications of the inserted hard drive. When hard drives of different dimensions are inserted, the lateral pressing member can make different degrees of clearance and continuously press the hard drive against the lateral reference part. Thus, the size difference between hard drives of different specifications is mainly compensated by the movement of the lateral pressing member, while the position of the hard drive relative to the supporting reference part and the lateral reference part remains stable, allowing the connection interface of hard drives of different specifications to be aligned with the connector located at the connection end and complete the insertion.

[0024] After the hard drive and connector are in the plugged-in state, the locking component engages with the locking part on the hard drive, restricting the hard drive from moving in the opposite direction to the insertion direction. This keeps the hard drive in the plugged-in position, reducing the risk of shaking, dislodgement, or loosening of the connection when the server is subjected to vibration or external force. Based on this engagement, the same multi-size hard drive through-hole module can install any of at least two different sizes of hard drives, eliminating the need for pre-assembling a separate hard drive frame corresponding to each size for each hard drive. This reduces hard drive installation steps and separate materials, lowers the risk of hard drive frame mismatch or loss, and improves the convenience of server delivery, expansion, and maintenance.

[0025] The server provided by this invention enables the server to directly install hard drives of different specifications by setting the above-mentioned multi-specification hard drive direct-plug modules in the chassis, thereby improving the flexibility of server storage configuration and simplifying the hard drive installation and maintenance process.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The core of this invention is to provide a multi-specification hard drive direct-insertion module, enabling at least two types of hard drives to be directly inserted into the same guide channel, and completing the positioning of the connection interface through a common support reference and lateral reference. Another core aspect of this invention is to provide a server including the aforementioned multi-specification hard drive direct-insertion module.

[0031] It should be noted that the insertion direction F referred to in this document is the direction in which the hard disk 3 moves from the insertion port 211 of the module frame 21 towards the connection end 212. The supporting surface referred to in this document is the surface of the supporting base 41 facing the guide channel 213 and used to directly support the hard disk housing 33; the module frame 21 has a base plate located below the guide channel 213, and the supporting surface and the base plate are not of the same structure. The width direction of the guide channel 213 is perpendicular or substantially perpendicular to the insertion direction F in the plane containing the supporting surface; the thickness direction of the hard disk 3 is perpendicular or substantially perpendicular to the supporting surface. The front or front end referred to in this document generally refers to the side closer to the insertion port 211, and the rear or rear end generally refers to the side closer to the connection end 212. The above orientations are only used to illustrate the relative relationships of the components and do not constitute a limitation on the actual installation direction of multi-specification hard disk through-hole modules.

[0032] It should also be noted that the terms "first," "second," etc., are only used to distinguish identical or similar structures and do not indicate the order or importance of the corresponding structures. This embodiment uses a first-specification hard drive 31 and a second-specification hard drive 32 as two hard drives 3 with different external dimensions, and these two hard drives 3 use the same or mutually compatible connection interface reference. Specifically, the first-specification hard drive 31 is wider and thicker, while the second-specification hard drive 32 is narrower and thinner. For example, the first-specification hard drive 31 can be a 3.5-inch hard drive, and the second-specification hard drive 32 can be a 2.5-inch hard drive. This application does not limit the specific dimensions of the two hard drives 3 when the interface form and positioning reference are compatible.

[0033] Please refer to Figures 2 to 6 The multi-specification hard drive through-hole module 2 includes a module frame 21, a connector 6, a positioning structure 4, a specification adapter component 5, and a locking component 7.

[0034] The module frame 21 is used for installation within the chassis 11 of the server 1. In this embodiment, the module frame 21 can be formed by connecting a base plate located below the guide channel 213, side walls located on both sides of the guide channel 213, and a connection end support structure located at the connection end 212, and forming a guide channel 213 extending from the insertion port end 211 to the connection end 212 within it. A supporting reference part 41 is provided on the side of the base plate facing the guide channel 213. The cross-sectional dimensions of the guide channel 213 are sufficient to accommodate the larger hard drives among the various hard drives 3 to be compatible, and provide a common insertion path for hard drives 3 of different specifications.

[0035] Connector 6 is located at connection end 212, and the insertion direction of connector 6 is the same as or substantially the same as the insertion direction F. Hard disk 3 includes a hard disk housing 33 and a connection interface 34 located at the end of the hard disk housing 33 facing connection end 212. When hard disk 3 moves along guide channel 213 to connection end 212, connection interface 34 engages with connector 6, thereby establishing an electrical and signal connection between hard disk 3 and server 1. Connector 6 can be a hot-swappable connector adapted to SATA, SAS, or other server hard disk interfaces, depending on the common or mutually compatible interface type used by the hard disk 3 to be compatible.

[0036] The positioning structure 4 is disposed within the guide channel 213 and includes a supporting reference portion 41 and a lateral reference portion 42. The supporting reference portion 41 supports the bottom surface of the hard disk housing 33 to establish a positional reference for the hard disk 3 in the thickness direction. The lateral reference portion 42 is disposed on one side of the guide channel 213 and is used for one side of the hard disk housing 33 to abut against, thereby establishing a positional reference for the hard disk 3 in the width direction. The installation position of the connector 6 is determined based on the interface reference of the connection interface 34 of the various hard disks 3 to be compatible with relative to the common reference side and common reference surface of the hard disk housing 33, so that the connector 6 is positioned relative to the supporting reference portion 41 and the lateral reference portion 42 in a position that allows alignment with the connection interface 34 of the various hard disks 3.

[0037] The specification adapter component 5 is disposed opposite to the lateral reference portion 42. The specification adapter component 5 includes a lateral clamping member 51 that can move relative to the module frame 21. The lateral clamping member 51 abuts against the side of the hard disk housing 33 away from the lateral reference portion 42 and applies a force toward the lateral reference portion 42 to the hard disk housing 33. When hard disks 3 of different widths enter the guide channel 213, the hard disk housing 33 pushes the lateral clamping member 51 away from the lateral reference portion 42 by different distances, while the lateral clamping member 51 continuously presses the other side of the hard disk housing 33 against the lateral reference portion 42. Thus, the lateral clamping member 51 compensates for the width differences of hard disks 3 of different specifications with different clearance amounts, so that all hard disks 3 of different specifications use the lateral reference portion 42 as a common positioning reference in the width direction, and keeps the position of the connection interface 34 consistent in the width direction.

[0038] When the hard disk 3 moves from the insertion port 211 to the connection port 212, the supporting reference part 41 provides support from the bottom side of the hard disk housing 33, the lateral reference part 42 provides a lateral positioning reference from one side of the hard disk housing 33, and the lateral pressing member 51 moves according to the width of the hard disk 3 and continuously presses the hard disk 3 against the lateral reference part 42. Thus, the width difference between hard disks 3 of different specifications is mainly compensated by the different amounts of lateral pressing members 51. Each hard disk 3 uses the supporting reference part 41 and the lateral reference part 42 as a common positioning reference, so that the connection interface 34 of hard disks 3 of different specifications can be aligned with the connector 6 provided at the connection port 212 and completed.

[0039] After the connection interface 34 is plugged into the connector 6, the locking component 7 engages with the locking part 35 of the hard disk 3 to restrict the movement of the hard disk 3 in the opposite direction to the insertion direction F, keeping the hard disk 3 in the plugged position and reducing the risk of shaking, disengagement, or loosening of the connection when the server 1 is subjected to vibration or the hard disk 3 is subjected to external force. Through the above-mentioned common insertion path, support positioning, lateral positioning, specification compensation, interface plugging, and locking relationship, the same multi-specification hard disk through-hole module 2 can selectively install at least two different specifications of hard disk 3 without pre-assembling an independent hard disk frame corresponding to each specification for each hard disk 3. This reduces the installation steps and independent materials of the hard disk 3, reduces the risk of hard disk frame mismatch or loss, and improves the convenience of server 1 delivery, expansion, and maintenance.

[0040] Please refer to Figure 2 , Figures 4 to 6 In an optional embodiment, there are at least two support bases 41, which are spaced apart along the width direction of the guide channel 213. Each support base 41 is strip-shaped extending in the insertion direction F, and its surface facing the guide channel 213 forms a support surface for supporting the bottom surface of the hard disk housing 33. The spacing between adjacent support bases 41 can reduce the contact area between the hard disk housing 33 and the module frame 21, and can also serve as space for arranging the connector 6, the ejection assembly 8, or other components.

[0041] In this embodiment, the lateral reference portion 42 is a fixed reference guide rail extending along the insertion direction F. The fixed reference guide rail can be integrally formed with the module frame 21, or it can be fixed to the module frame 21 by fastening, welding, or snap-fitting. The surface of the lateral reference portion 42 facing the guide channel 213 can be a continuous reference surface, or it can include multiple coplanar abutment areas spaced apart along the insertion direction F. The supporting reference portion 41 and the lateral reference portion 42 near the insertion port end 211 can also be provided with chamfers or rounded transitions to facilitate the entry of the hard disk 3 into the guide channel 213.

[0042] Please refer to Figures 4 to 6In one optional embodiment, there are at least two lateral clamping members 51, which are spaced apart along the insertion direction F. Each lateral clamping member 51 is movably connected to the module frame 21 and can independently make room for each other according to the width of the hard disk 3 and the assembly tolerance at its contact position. Compared to clamping the hard disk 3 at only a single position, multiple lateral clamping members 51 distributed along the insertion direction F can apply a force toward the lateral reference portion 42 at different positions before and after the hard disk 3, thereby reducing the risk of the hard disk 3 being misaligned relative to the insertion direction F.

[0043] Each lateral holding member 51 may include an adaptable rocker arm 511, a first rotating shaft 512, a lateral roller 513, and a first torsion spring 514. Figure 4 and Figure 5 In the specific arrangement shown, the first rotating shaft 512 and the limiting block 515 are both disposed on the side of the bottom plate of the module frame 21 facing the guide channel 213, and adjacent to the side wall of the module frame 21 opposite to the lateral reference part 42. One end of the adapter rocker arm 511 is rotatably connected to the module frame 21 via the first rotating shaft 512, and the lateral roller 513 is rotatably disposed at the other end of the adapter rocker arm 511 and is used to abut against the hard disk housing 33. The first torsion spring 514 is sleeved on the first rotating shaft 512, and one end of the spring acts on the adapter rocker arm 511, while the other end of the spring acts on the module frame 21 to drive the lateral roller 513 to swing toward the lateral reference part 42.

[0044] The rotation axis of the lateral roller 513 can be aligned with or substantially aligned with the thickness direction of the hard disk 3. When the hard disk 3 moves along the insertion direction F, the lateral roller 513 rolls on the side of the hard disk housing 33, which can reduce the influence of the size adapter component 5 on the insertion resistance. The module frame 21 is also provided with a limiting block 515 that cooperates with the adapter rocker arm 511. When there is no hard disk 3 in the guide channel 213, the limiting block 515 restricts the adapter rocker arm 511 from continuing to rotate into the guide channel 213 under the action of the first torsion spring 514, so that the lateral roller 513 is kept in a predetermined initial position that facilitates the reception of the hard disk 3.

[0045] like Figure 5 and Figure 6 As shown, when the wider first-size hard drive 31 is inserted, the adapter rocker arm 511 rotates further away from the lateral reference portion 42 under the push of the hard drive housing 33; when the narrower second-size hard drive 32 is inserted, the adapter rocker arm 511 rotates a small angle relative to its initial position, and the lateral roller 513 still applies a pressing force to the hard drive housing 33. In both states, the reference side of the hard drive housing 33 abuts against the lateral reference portion 42, thus the position of the connection interface 34 remains consistent in the width direction.

[0046] The lateral holding member 51 is not limited to the rocker arm and roller structure described above. For example, while maintaining force on the lateral reference portion 42 and allowing for clearance, the lateral holding member 51 can also be a combination structure of an elastic pressure block, a leaf spring, a linear slider, and a compression spring. When multiple lateral holding members 51 are used, each lateral holding member 51 can have the same structure, or it can be configured with different structures according to the space at different positions within the guide channel 213.

[0047] Please refer to Figure 7 and Figure 8 To further accommodate hard drives 3 of different thicknesses, the size adaptation component 5 may also include an upper pressing member 52 disposed opposite to the supporting reference portion 41. At least a portion of the upper pressing member 52 is movable in a direction toward or away from the supporting reference portion 41, and abuts against the upper side of the hard drive housing 33 under an elastic force toward the supporting reference portion 41. When the thicker first-size hard drive 31 is inserted, the upper pressing member 52 makes a greater concession in the direction away from the supporting reference portion 41; when the thinner second-size hard drive 32 is inserted, the upper pressing member 52 makes a smaller concession, and still presses the hard drive housing 33 toward the supporting reference portion 41. Thus, both types of hard drives 3 use the supporting reference portion 41 as a common positioning reference in the thickness direction.

[0048] In one specific embodiment, the upper holding member 52 includes an upper rocker arm 521, a second rotating shaft 522, an upper roller 523, and a second torsion spring 524. One end of the upper rocker arm 521 is rotatably connected to the module frame 21 via the second rotating shaft 522, and the upper roller 523 is rotatably disposed at the other end of the upper rocker arm 521. The second torsion spring 524 is sleeved on the second rotating shaft 522 and acts on the upper rocker arm 521 and the module frame 21 respectively to drive the upper roller 523 to swing toward the support base part 41.

[0049] Figure 7 and Figure 8 This is a schematic diagram of the transverse cross-sectional structure viewed along the length of guide channel 213, i.e., the insertion direction F. Figure 7 and Figure 8In the diagram, the horizontal direction corresponds to the width of the guide channel 213, and the vertical direction corresponds to the height of the guide channel 213. A fixed plate can be installed at the top of the module frame 21. One end of the upper rocker arm 521 is rotatably mounted on the fixed plate via a second rotating shaft 522, and the upper roller 523 is rotatably mounted at the other end of the upper rocker arm 521. The axis of the second rotating shaft 522 and the rotation axis of the upper roller 523 both extend along the length of the guide channel 213, and they are parallel to each other and spaced apart. When the hard disk 3 moves along the insertion direction F, the upper roller 523 can roll around its rotation axis on the upper surface of the hard disk housing 33 to reduce the influence of the upper holding member 52 on the insertion resistance of the hard disk 3. There can be one upper holding member 52, or multiple members can be spaced apart along the insertion direction F. The lateral pressing member 51 and the upper pressing member 52 compensate for the dimensional differences of the hard disk 3 in the width and thickness directions, respectively, so that hard disks 3 of different specifications are pressed against the common lateral reference part 42 and the supporting reference part 41.

[0050] Please refer to Figures 9 to 11 The module frame 21 has a terminal guide 214 at the connection end 212. The terminal guide 214 has a guide surface 215 that gradually slopes inward toward the guide channel 213 along the insertion direction F toward the connection end 212. The guide surface 215 can be provided at least one of the two sides, the upper side, and the lower side of the area that the connection interface 34 passes through before entering the connector 6. When the hard disk 3 approaches the connection end 212, the hard disk housing 33 or the housing area near the connection interface 34 cooperates with the guide surface 215 to gradually correct the remaining positional deviation of the hard disk 3 relative to the connector 6.

[0051] Connector 6 is a hot-pluggable connector and is mounted on a floating connector 61. The floating connector 61 is buoyantly mounted on the connection end 212 via elastic sleeves 62. Specifically, a support plate may be provided on the connection end 212, and the floating connector 61 is connected to the support plate via multiple elastic sleeves 62. Fasteners pass through the elastic sleeves 62 and the floating connector 61, with a radial clearance between the fasteners and the corresponding mounting holes of the floating connector 61. While restricting the floating connector 61 from disengaging along the insertion direction F, the fasteners allow the elastic sleeves 62 to provide a small amount of movement space for the floating connector 61 in a plane perpendicular to the insertion direction F through radial elastic deformation.

[0052] The elastic sleeve 62 can be made of rubber, elastomer, or a composite material with radial elasticity. When there is a slight lateral or vertical deviation between the connection interface 34 and the connector 6, the terminal guide 214 first guides the hard disk 3; after the connector 6 is inserted into the connection interface 34, the insertion force can also cause the elastic sleeve 62 to elastically deform, so that the floating connector 61 and the connector 6 move in a plane perpendicular to the insertion direction F. The terminal guide and the floating connector work together to reduce the risk of misalignment of the connection interface 34 due to accumulated assembly errors.

[0053] Please refer to Figures 12 to 14 The locking assembly 7 may include a locking pin 71 and a locking spring 72. The locking pin 71 passes through a guide hole in the module frame 21 and can extend into or out of the guide channel 213 along the width direction of the guide channel 213. Each locking pin 71 is respectively equipped with a locking spring 72, which is disposed between the corresponding locking pin 71 and the module frame 21, and is used to independently apply a force toward the guide channel 213 to the corresponding locking pin 71.

[0054] The locking engagement part 35 of the hard disk 3 can be formed using the existing side mounting hole 351 on the side of the hard disk housing 33. The end of the locking pin 71 that extends into the guide channel 213 has a guide slope 711 facing the insertion end 211 and a stop surface 712 facing the connection end 212. When the hard disk 3 is inserted, the side edge of the hard disk housing 33 facing the connection end 212 pushes against the guide slope 711, causing the locking pin 71 to temporarily exit the guide channel 213 against the force of the locking spring 72; when the connection interface 34 is inserted into the connector 6 and the side mounting hole 351 is aligned with the locking pin 71, the locking pin 71 extends into the side mounting hole 351 under the action of the locking spring 72.

[0055] When the hard disk 3 is subjected to a force opposite to the insertion direction F, the wall of the side mounting hole 351 facing the connection end 212 abuts against the stop surface 712. Since the stop surface 712 does not form a guide slope to facilitate the withdrawal of the locking pin 71, the locking pin 71 can restrict the movement of the hard disk 3 towards the insertion end 211. There can be one or more side mounting holes 351. When multiple locking pins 71 are provided, multiple locking pins 71 can respectively cooperate with multiple side mounting holes 351 on the same hard disk housing 33, or locking pins 71 at different positions can correspond to the side mounting holes 351 of different specifications of hard disk 3, and locking is achieved by the locking pin 71 corresponding to the current hard disk 3.

[0056] In an optional embodiment, there are at least two locking pins 71, spaced apart along the insertion direction F. The locking assembly 7 also includes a common unlocking plate 73, an unlocking transmission rod 74, and an unlocking button 75. The common unlocking plate 73 is provided with traction holes corresponding to each locking pin 71. The rod portion of each locking pin 71 passes through the corresponding traction hole, and the end of the rod portion away from the guide channel 213 is provided with a traction limiting portion that can abut against the common unlocking plate 73. The traction holes provide space for the locking pins 71 to move independently in the direction of extending into or out of the guide channel 213. The common unlocking plate 73 can move relative to the module frame 21 in the direction of approaching or moving away from the guide channel 213. When the common unlocking plate 73 moves away from the guide channel 213, it abuts against each traction limiting portion to drive each locking pin 71 to move synchronously in the direction of exiting the guide channel 213. When the common unlocking plate 73 returns to its original position near the guide channel 213, it releases the pull on each locking pin 71, allowing each locking pin 71 to move independently under the action of the corresponding locking spring 72.

[0057] The unlocking transmission rod 74 is movably mounted on the module frame 21 along the insertion direction F. The unlocking button 75 is located at the insertion port end 211 and connected to the unlocking transmission rod 74. The common unlocking plate 73 is provided with a cam groove 731 inclined relative to the insertion direction F, and the unlocking transmission rod 74 is provided with a follower part 741 extending into the cam groove 731. In specific unlocking, the operator presses the unlocking button 75, which drives the unlocking transmission rod 74 to move along the insertion direction F. The follower part 741 moves along the cam groove 731 and pushes against the groove wall of the cam groove 731, thereby converting the movement of the unlocking transmission rod 74 along the insertion direction F into the movement of the common unlocking plate 73 in a direction away from the guide channel 213. The common unlocking plate 73 further pulls the corresponding locking pins 71 simultaneously through each traction limiting part, so that each locking pin 71 overcomes the force of the corresponding locking spring 72 and simultaneously exits the side mounting hole 351. Thus, the pressing force of the unlock button 75 is transmitted sequentially through the unlock transmission rod 74, the follower part 741 and the cam groove 731, and the common unlock plate 73 to each lock stop pin 71.

[0058] After the unlocking operation is completed, the operator moves the unlocking button 75 and the unlocking transmission rod 74 to their initial positions in the opposite direction to the insertion direction F. The follower 741 moves in the opposite direction along the cam groove 731 with the unlocking transmission rod 74, causing the common unlocking plate 73 to move closer to the guide channel 213 and releasing the pull on each locking pin 71. Each locking pin 71 moves into the guide channel 213 under the action of the corresponding locking spring 72. The locking pin 71 aligned with the side mounting hole 351 of the current hard disk 3 enters the side mounting hole 351, while the locking pin 71 not aligned with the side mounting hole 351 abuts against the hard disk housing 33 and remains in a corresponding clearance state.

[0059] With the above settings, the operator only needs to operate one unlock button 75 to make at least two locking pins 71 exit simultaneously and release the lock on the hard drive 3; after the common unlocking plate 73 is released and pulled out, each locking pin 71 can independently enter or move aside depending on whether it is aligned with the corresponding side mounting hole 351, thus taking into account both unified unlocking and locking adaptation of hard drives 3 of different specifications.

[0060] Please refer to Figure 15 To facilitate the removal of the hard drive 3 after the independent hard drive frame is removed, the multi-size hard drive through-hole module 2 may also include an ejection assembly 8. The ejection assembly 8 includes an ejection plate 81, a guide rod 82, and an ejection spring 83. The guide rod 82 is fixed to the module frame 21 along the insertion direction F. The ejection plate 81 has a guide hole through which the guide rod 82 passes and can slide along the guide rod 82. The ejection plate 81 is located near the connection end 212. The ejection spring 83 is disposed between the ejection plate 81 and the module frame 21; for example, the ejection spring 83 can be sleeved on the outside of the guide rod 82, or it can be clamped between the ejection plate 81 and the connection end support structure of the module frame 21 along the extension direction of the guide rod 82.

[0061] The ejector plate 81 includes two abutment portions 811 spaced apart along the thickness direction of the hard disk 3. The two abutment portions 811 are located on opposite sides of the area traversed by the connection interface 34 and the connector 6, respectively, and a connector clearance area 812 is formed between the two abutment portions 811. During the insertion process, the connection interface 34 and the connector 6 can enter the connector clearance area 812, so that the ejector plate 81 will not obstruct the insertion of the connection interface 34 and the connector 6. Depending on the end face shape of the different hard disks 3, the two abutment portions 811 can simultaneously abut against the end face of the hard disk housing 33 facing the connection end 212, or only one of the abutment portions 811 can abut against that end face.

[0062] When the hard disk 3 moves toward the connection end 212, its end face facing the connection end 212 pushes the ejection plate 81 along the guide rod 82 through at least one pushing part 811, compressing the ejection spring 83 and causing the ejection spring 83 to store energy. Figure 15 As shown in (a). After the connection interface 34 and connector 6 are inserted into place, the locking assembly 7 holds the hard disk 3 in the connected position. The force of the push-out spring 83 is borne by the locking assembly 7, thus the hard disk 3 remains in the connected position in the locked state. When the locking assembly 7 separates from the locking engagement part 35, the push-out spring 83 drives the push-out plate 81 to move toward the insertion end 211, thereby pushing the hard disk 3 out a predetermined distance, so that the front end of the hard disk 3 forms a part that can be grasped by the operator, such as... Figure 15 As shown in (b).

[0063] With the above settings, when the hard disk 3 is inserted, it can push the ejector plate 81 to move backward and cause the ejector spring 83 to store energy synchronously. After the locking component 7 is released, the ejector spring 83 drives the ejector plate 81 to automatically return to the ejection position and pushes the hard disk 3 toward the insertion port 211 a predetermined distance, so that the hard disk 3 forms an exposed part that is easy for the operator to grasp, thereby realizing automatic ejection after the lock is released, and there is no need to manually reset the ejector plate 81 separately.

[0064] Please refer to the reference. Figures 16 to 19 To adapt the ejection distance to different specifications of hard drives 3, the ejection plate 81 includes a push plate body perpendicular to the insertion direction F and a limiting extension extending from one end of the push plate body along the insertion direction F. The limiting extension is integrally connected to the push plate body and moves synchronously with the push plate body. A stroke groove 813 is formed in the limiting extension along the insertion direction F. The module frame 21 is provided with a first stroke stop 84, a second stroke stop 85, and a stroke selection member 86. The first stroke stop 84 and the second stroke stop 85 are spaced apart along the insertion direction F and can selectively enter the stroke groove 813. When the ejection plate 81 moves towards the insertion port end 211 to the corresponding position under the action of the ejection spring 83, the selected stroke stop abuts against the end wall of the stroke groove 813 toward the connection end 212 to limit the continued movement of the ejection plate 81.

[0065] In one specific implementation, both the first stroke stop 84 and the second stroke stop 85 are stop pins, movably inserted into the base plate in a direction perpendicular to the base plate of the module frame 21. Each stop pin is provided with a return spring for driving it out of the stroke slot 813. The stroke selection member 86 includes a driver disposed on the base plate and a selection slider connected to the drive end of the driver. The driver is electrically connected to the control unit and can move the selection slider between a first selection position and a second selection position under the control of the control unit. The selection slider has two selection engagement areas corresponding to the first stroke stop 84 and the second stroke stop 85, respectively. When the selection slider is in the first selection position, the selection engagement area corresponding to the first stroke stop 84 forms a high-push position, and the selection engagement area corresponding to the second stroke stop 85 forms a low-avoidance position; when the selection slider is in the second selection position, the selection engagement area corresponding to the first stroke stop 84 forms a low-avoidance position, and the selection engagement area corresponding to the second stroke stop 85 forms a high-push position.

[0066] When the stroke selector 86 is in the first selection state, the driver moves the selection slider to the first selection position. The high-push position overcomes the force of the corresponding return spring, causing the first stroke stop 84 to extend into the stroke groove 813. The low-yield position allows the second stroke stop 85 to exit the stroke groove 813 under the action of the corresponding return spring. When the stroke selector 86 is in the second selection state, the driver moves the selection slider to the second selection position. The high-push position causes the second stroke stop 85 to extend into the stroke groove 813. The low-yield position allows the first stroke stop 84 to exit the stroke groove 813. The high-push and low-yield positions can be connected by a transition ramp to gradually push or release the corresponding stop pin during the movement of the selection slider. Thus, in any selection state, only one stroke stop engages with the stroke groove 813. Before the ejection assembly 8 begins ejecting the hard disk 3, the control unit can control the driver to switch the position of the selection slider according to the received stroke selection command, automatically selecting the ejection stroke compatible with the hard disk 3 without manual adjustment.

[0067] Because the first stroke stop 84 and the second stroke stop 85 are positioned differently along the insertion direction F, the ejector plate 81 can form different termination positions in the two selection states, thereby forming ejection strokes corresponding to the first specification hard disk 31 and the second specification hard disk 32 respectively. The stroke selection component 86 can be preset when assembling the multi-specification hard disk through-hole module 2, or it can be set in a position convenient for maintenance personnel to operate, and can be switched according to the specification of the hard disk 3 to be installed.

[0068] Please refer to Figure 20 and Figure 21 In another optional embodiment, the multi-size hard drive through-hole module 2 further includes a support slide 9 disposed within the guide channel 213. It should be noted that... Figure 20 and Figure 21 This diagram primarily illustrates the cooperation relationship between the support slide 9, the supporting reference part 41, and the anti-detachment groove 92 and the anti-detachment pin 93. For clarity, the lateral reference part 42, the lateral pressing member 51, the connector 6, and the locking assembly 7 are not shown repeatedly, although this embodiment still includes the aforementioned structures. The support slide 9 is slidably disposed in the guide channel 213 along the insertion direction F, and the hard disk 3 is detachably supported on the support slide 9. The support slide 9 may be provided with limiting edges or limiting protrusions that cooperate with the front and rear faces of the hard disk housing 33, so that the hard disk 3 and the support slide 9 are limited in the insertion direction F. After the support slide 9 moves to the loading / unloading position, the hard disk 3 can be inserted or removed along its thickness direction. The limiting edges or limiting protrusions achieve insertion direction limitation without hindering the installation and removal of the hard disk 3. The supporting reference part 41 is disposed on the support slide 9 and directly supports the hard disk housing 33.

[0069] An operating part 91 is provided at one end of the support slide 9 near the insertion port 211. The operating part 91 can be a handle, a flip handle, or a recess for applying force with fingers. The operator pushes the support slide 9 and the hard disk 3 toward the connection port 212 through the operating part 91, so that the connection interface 34 is inserted into the connector 6; when disassembly is required, the operator pulls the support slide 9 and the hard disk 3 toward the insertion port 211 through the operating part 91, so that the connection interface 34 is separated from the connector 6.

[0070] One of the module frame 21 and the support slide 9 is provided with an anti-detachment groove 92 extending along the insertion direction F, and the other is provided with an anti-detachment pin 93 extending into the anti-detachment groove 92. In this embodiment, the anti-detachment groove 92 is provided on the side of the support slide 9, and the anti-detachment pin 93 is fixed to the bottom plate of the module frame 21 and extends into the anti-detachment groove 92 from the bottom plate toward the guide channel 213. When the support slide 9 moves, the anti-detachment pin 93 can move relative to the anti-detachment groove 92, and when the support slide 9 reaches the loading / unloading position, it cooperates with the end stop of the anti-detachment groove 92 to prevent the support slide 9 from detaching from the guide channel 213.

[0071] In this embodiment, the support slide 9 is added to the lateral reference part 42, the lateral pressing member 51, the connector 6, and the locking assembly 7. The support slide 9 has clearance areas at positions corresponding to the lateral pressing member 51, the connector 6, and the locking assembly 7, so that the lateral pressing member 51 can abut against the hard disk housing 33, the connection interface 34 can be inserted into the connector 6, and the locking assembly 7 can engage with the locking mating part 35. When the locking pin 71 engages with the side mounting hole 351, the support slide 9 has clearance openings for the locking pin 71 to pass through or extend into the side mounting hole 351. The upper pressing member 52 and the in-situ detection assembly 22 can be further configured as needed, and the support slide 9 is correspondingly provided with clearance areas.

[0072] The carrier slide 9 is a modular component housed within the server 1. It is held in the guide channel 213 by the cooperation of the anti-detachment groove 92 and the anti-detachment pin 93, and does not rotate with the hard drive 3. When replacing the hard drive 3, the operator simply removes the hard drive 3 from the carrier slide 9, eliminating the need to configure and manage an independent hard drive frame that rotates with each hard drive 3. Therefore, the carrier slide 9 can provide a gripping operation unit 91 while still reducing the steps of installing individual hard drive frames one by one.

[0073] Please refer to Figure 22 and Figure 23The multi-specification hard drive through-hole module 2 may also include an in-place detection component 22. The in-place detection component 22 is correspondingly positioned to the guide channel 213, with its detection body fixed to the bottom plate of the module frame 21 on the side facing the guide channel 213 and located near the connection end 212. The in-place detection component 22 and the connector 6 are offset along the width direction of the guide channel 213. The in-place detection component 22 can be a micro-motion detector with a retractable trigger portion, the trigger portion extending towards the guide channel 213 in the direction opposite to the insertion direction F. When the hard drive 3 has not yet reached the predetermined insertion depth, a gap remains between the end face of the hard drive housing 33 facing the connection end 212 and the trigger portion; as the hard drive 3 continues to move along the insertion direction F and the connection interface 34 and connector 6 are inserted into place, the end face of the hard drive housing 33 presses against the trigger portion, causing the in-place detection component 22 to output an in-place signal for the hard drive 3.

[0074] The predetermined insertion depth preferably corresponds to the connection interface 34 and connector 6 reaching a specified insertion depth, and the locking pin 71 being able to enter the side mounting hole 351. To reduce the possibility of prematurely outputting a presence signal before the hard disk 3 is reliably inserted, the trigger position of the presence detection component 22 can be set at the end of the travel of the hard disk 3 near the final connection position. The presence detection component 22 can also employ a Hall sensor, photoelectric sensor, spring contact, or connector short-circuit detection structure, as long as it can output a presence signal when the hard disk 3 reaches the predetermined insertion depth.

[0075] Please refer to Figures 1 to 3 The server 1 includes a chassis 11 and at least one of the aforementioned multi-specification hard drive through-hole modules 2. A front window 112 is provided at the front of the chassis 11, forming hard drive insertion ports 111 corresponding to each of the multi-specification hard drive through-hole modules 2. A module frame 21 is fixed inside the chassis 11, with the insertion port end 211 corresponding to the hard drive insertion port 111, and the connection end 212 facing inwards from the chassis 11. A connector 6 can be mounted on the backplate inside the chassis 11 via a floating connector 61, or it can be mounted on a connection end support structure fixedly connected to the backplate; in both configurations, the connector 6 is located at the connection end 212 of the corresponding module frame 21.

[0076] Figure 1 and Figure 3 Taking a twelve-disk front-panel server as an example, the twelve hard drive bays 111 can be arranged in three rows and four columns, with a multi-specification hard drive direct-insertion module 2 behind each hard drive bay 111. The insertion direction F of each multi-specification hard drive direct-insertion module 2 can be parallel to each other, and each connector 6 corresponds to the corresponding connection position on the back panel inside the chassis 11. The number of disk bays in the server 1 is not limited to twelve; it can also be set to eight, sixteen, twenty-four, or other numbers depending on the height of the chassis 11 and the storage configuration.

[0077] Please refer to Figure 1In this embodiment, server 1 includes multiple multi-specification hard drive through-hole modules 2, each of which is equipped with an in-situ detection component 22. Server 1 also includes a control unit and multiple display units 12 disposed outside chassis 11. The installation location of the control unit is not limited; it can be disposed on the back panel, server motherboard, front control board, or other circuit boards inside chassis 11. Each display unit 12 corresponds one-to-one with each multi-specification hard drive through-hole module 2.

[0078] The control unit receives the presence signals output by each presence detection component 22 and controls the display unit 12 corresponding to the corresponding multi-specification hard drive through-hole module 2 according to the presence signals. The display unit 12 can be a display area of ​​a light-emitting diode, a digital display area, or a display screen. Taking a light-emitting diode as an example, when the presence detection component 22 outputs a presence signal, the corresponding display unit 12 lights up; when no presence signal is output, the corresponding display unit 12 is off. The display unit 12 can also indicate maintenance prompts through different flashing patterns, but it can at least indicate whether the corresponding hard drive 3 is in place.

[0079] The following describes the installation and removal process of the hard disk 3 using a combined embodiment that simultaneously includes a lateral holding member 51, an upper holding member 52, a terminal guide 214, a connector 6 mounted via a floating connecting seat 61 and an elastic sleeve 62, a locking assembly 7 having a common unlocking plate 73, an unlocking transmission rod 74 and an unlocking button 75, an ejection assembly 8, a first stroke stop 84, a second stroke stop 85, a stroke selection member 86, and an in-place detection assembly 22 as an example. The operator first confirms the selection status of the stroke selection member 86 according to the specifications of the hard disk 3 to be installed, and aligns the connection interface 34 of the hard disk 3 towards the connection end 212. After the hard disk 3 enters the insertion end 211 through the hard disk insertion port 111, its bottom surface is supported by the supporting reference part 41, and the side of the hard disk casing 33 facing the lateral reference part 42 gradually presses against the lateral reference part 42. The lateral holding member 51 and the upper holding member 52 are pushed aside by the hard disk housing 33, and the hard disk 3 is continuously pressed against the lateral reference part 42 and the supporting reference part 41.

[0080] The hard disk 3 continues to move along the insertion direction F, and its side edge facing the connection end 212 pushes against the guide slope 711, causing the locking pin 71 to temporarily retract from the guide channel 213. Simultaneously, the end face of the hard disk 3 facing the connection end 212 pushes the ejection plate 81 through at least one pushing part 811, causing the ejection spring 83 to store energy. As the hard disk 3 approaches the connection end 212, the terminal guide part 214 further corrects its position, and the connector 6 can also generate a slight follow-up through the floating connector 61. After the connection interface 34 and the connector 6 are fully inserted, the locking pin 71 corresponding to the side mounting hole 351 enters the side mounting hole 351, the position detection component 22 is triggered and outputs a position signal, and the control unit controls the corresponding display unit 12 to indicate that the hard disk 3 is in position.

[0081] When the hard drive 3 needs to be removed, the operator first presses the unlock button 75. The unlocking transmission rod 74 drives the follower part 741 to move along the cam groove 731, causing the common unlocking plate 73 to pull each locking pin 71 synchronously towards the exit guide channel 213. After the lock is released, the push-out spring 83 drives the push-out plate 81 to push the hard drive 3 towards the insertion end 211 a distance limited by the current stop position. The operator grabs the front end of the hard drive 3 exposed in the front window 112 and pulls it out in the opposite direction to the insertion direction F. The carrier slide 9 is another removal method; when using the carrier slide 9, the operator pulls out the carrier slide 9 through the operating part 91, and after the anti-detachment pin 93 and the anti-detachment groove 92 stop at the end, the hard drive 3 is removed from the carrier slide 9.

[0082] After hard drive 3 is removed, the presence detection component 22 is detrimentalized, and the control unit controls the corresponding display unit 12 to update to the absence state. The lateral holding member 51, the upper holding member 52, the locking pin 71, and the ejection plate 81 are reset under the action of the corresponding elastic members to allow the next hard drive 3 to be inserted.

[0083] The embodiments described in this specification are presented in a progressive manner, with each embodiment focusing on the structural differences from other embodiments. Similar or identical parts can be referred to interchangeably. The ejection assembly 8 and the support slide 9 can serve as two different removal methods for the hard disk 3. Both removal methods are used in conjunction with the aforementioned lateral reference part 42, lateral holding member 51, connector 6, and locking assembly 7. The upper holding member 52, terminal guide part 214, floating connecting seat 61 and elastic sleeve 62, common unlocking plate 73 and unlocking transmission rod 74 and unlocking button 75, as well as the in-situ detection assembly 22 and display unit 12, can be further configured according to the available structural space. During assembly, necessary clearance areas are provided between the components to ensure that the corresponding components can operate in the aforementioned manner.

[0084] In summary, the multi-specification hard drive through-hole modules and servers provided by this invention, when used in combination with corresponding optional structures, mainly have the following core advantages: First, the guide channel 213 provides a common insertion path for at least two types of hard disks 3, the supporting reference part 41 and the lateral reference part 42 establish a common positioning reference, and the lateral holding member 51 compensates for the width difference of hard disks 3 of different specifications by moving to make room, so that hard disks 3 of different specifications can share the same direct insertion slot, and reduce the assembly and management burden brought about by configuring independent hard disk frames for each disk, thereby improving the flexibility of the storage configuration of the server 1 and simplifying the installation and maintenance process of the hard disks 3.

[0085] Second, the lateral pressing member 51 and the upper pressing member 52 can press the hard disk 3 against the corresponding reference in the width direction and the thickness direction, respectively. The terminal guide 214 and the floating connector 6 further compensate for the remaining position deviation when the hard disk 3 approaches the connection end 212, which helps to stably align the connection interface 34 and the connector 6 and complete the insertion.

[0086] Third, the locking component 7 can prevent the hard disk 3 from retracting after it is inserted into the hole; the common unlocking plate 73, the unlocking transmission rod 74 and the unlocking button 75 can enable the synchronous unlocking of at least two locking pins 71; the ejection component 8 can enable elastic ejection; the first stroke stop 84, the second stroke stop 85 and the stroke selection component 86 can limit the ejection stroke according to the specifications of the hard disk 3; the support slide 9 provides another gripping and anti-dislodgement method for removing the disk, thereby improving the convenience of disassembling, installing and maintaining the hard disk 3.

[0087] Fourth, the presence detection component 22 can output a presence signal when the hard drive 3 reaches the predetermined insertion depth. The control unit controls the display unit 12 corresponding to each of the multi-size hard drive through-hole modules 2 accordingly. Thus, multiple display units 12 can form a centralized presence display corresponding to each slot outside the chassis 11, realizing visualization of the hard drive slot-level status. This allows maintenance personnel to determine whether the hard drive 3 in each slot is in place from outside the chassis 11 without disassembling the chassis 11 or plugging and unplugging the hard drives 3 one by one.
