Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a hard disk module and a server. Background Art

[0002] With the continuous development of information technology, the amount of data generated by data centers during operation has also grown explosively, which requires servers to provide as much storage capacity as possible within a limited space to meet the data center's needs for space and energy efficiency.

[0003] However, in the related art, in order to increase the number of hard disks to increase the total storage space of the server, it is often necessary to change the hard disk slots and hard disk backplane of the server chassis, resulting in major changes in the overall architecture of the server and high R&D costs. Summary of the invention

[0004] In view of this, the present invention provides a hard disk backplane and a hard disk module to solve the problem of high R&D cost for expanding the capacity of a hard disk system in the related art.

[0005] In a first aspect, the present invention provides a hard disk module, comprising:

[0006] Hard disk tray;

[0007] At least two hard disks are stacked along the thickness direction of the hard disks and are arranged in the hard disk bracket;

[0008] The adapter board includes a first connector, a second connector and a card body. The first connector is on one side surface of the card body. An integrated circuit is formed on the card body. The input end of the integrated circuit is connected to the first connector. The integrated circuit can convert the signal input from the hard disk backplane into at least two signals. There are at least two second connectors, which are arranged on the other side surface of the card body and connected to the output end of the integrated circuit. Each second connector is used to connect a hard disk.

[0009] Beneficial effect: The hard disk module of the embodiment of the present invention includes an adapter board, and the first connector on one side of the adapter board can receive the signal input by the hard disk backplane, and the integrated circuit on the adapter board can convert the signal input by the hard disk backplane into at least two signals. Through such a configuration, the hard disk module of the embodiment of the present invention can set two hard disks in one hard disk bracket, and realize the connection between the hard disk and the hard disk backplane through the adapter board, thereby enabling each hard disk bracket and hard disk frame to accommodate two hard disks on the basis of the original system architecture unchanged, thereby realizing the expansion of the hard disk system without changing the structure at the front window of the chassis (that is, the hard disk frame and the hard disk backplane), thereby significantly expanding the capacity of the storage system without increasing the research and development cost of the server, and greatly improving the space utilization rate in the hard disk module, so that the original server hard disk installation slot is doubled.

[0010] Furthermore, since the hard disk module of the embodiment of the present invention does not need to adjust the original architecture of the server, it can reduce the potential risks caused by the transformation and improve the stability of the system. The hard disk module of the embodiment of the present invention has good scalability and can easily add more hard disks as needed to meet the growing storage needs.

[0011] In an optional embodiment, the hard disk module also includes an adapter bracket for connecting to a hard disk bracket, the adapter bracket is provided with an installation slot and an avoidance opening, at least two hard disks are arranged in the installation slot, the adapter plate is connected to one end of the adapter bracket, and the second connector can pass through the avoidance opening to connect to the hard disk.

[0012] Beneficial effects:

[0013] By such arrangement, the adapter bracket can be used to limit the hard disk and install the adapter plate. During the assembly process, the operator can first install the adapter plate at one end of the adapter bracket, install the hard disk into the installation slot of the adapter bracket, and make the hard disk plug into the second connector of the adapter bracket, then fix the adapter plate to the adapter bracket, and finally connect the adapter bracket to the hard disk bracket.

[0014] In an optional embodiment, a first connection structure is provided on the adapter bracket, and a second connection structure is provided on the adapter plate, and the first connection structure can be detachably connected to the second connection structure.

[0015] Beneficial effect: The adapter plate is detachably connected to the adapter bracket, which makes it easy to replace the adapter plate when a failure occurs in the adapter plate, so that the adapter bracket can be reused.

[0016] In an optional embodiment, the first connection structure includes:

[0017] a first connecting hole;

[0018] The first connection hole and the limiter are respectively arranged on both sides of the avoidance opening and are spaced apart along the thickness direction of the hard disk. The limiter comprises a connection section and a clamping head which are sequentially connected in a direction away from the hard disk, and the cross-sectional area of ​​the connection section is smaller than the cross-sectional area of ​​the clamping head.

[0019] The second connection structure includes:

[0020] a second connecting hole, the second connecting hole being capable of allowing a fastener to pass through and connecting to the first connecting hole;

[0021] The third connecting hole and the second connecting hole are arranged at intervals. The third connecting hole has a first hole segment and a second hole segment. The first hole segment and the second hole segment are connected to each other. The area of ​​the first hole segment is larger than the cross-sectional area of ​​the clamping head and can allow the limiting member to pass through. The area of ​​the second hole segment is larger than the cross-sectional area of ​​the connecting segment and smaller than the cross-sectional area of ​​the clamping head. The limiting member can enter the second hole segment from the first hole segment and limit the adapter plate on the adapter bracket when it is in the second hole segment.

[0022] Beneficial effect: When the adapter plate needs to be connected to the adapter bracket, the operator can first pass the limiting member through the first hole section of the third connection hole, then move the adapter plate, snap the limiting member into the second hole section of the third connection hole, so as to pre-position the adapter plate on the limiting member, and finally pass the fastener through the second connection hole and the first connection hole, so as to lock the adapter plate on the adapter bracket. In addition, since the second connection hole and the third connection hole are diagonally distributed on the adapter plate, the left-right balance can be ensured during the process of disassembling and installing the hard disk.

[0023] In an optional embodiment, the adapter bracket includes:

[0024] A cover shell, used for connecting a hard disk bracket;

[0025] The first reinforcing rib is arranged in the cover shell and extends along the length direction of the hard disk. The mounting groove is formed between the first reinforcing rib and a side wall of the cover shell.

[0026] Beneficial effect: By such arrangement, the first reinforcing rib can not only be used to separate the installation slot capable of accommodating the hard disk in the housing, but also can improve the structural strength of the housing. When the adapter bracket is a plastic part, the first reinforcing rib can also facilitate demoulding of the adapter bracket.

[0027] In an optional embodiment, a fourth connecting hole is respectively provided on the first reinforcing rib and the first side wall of the cover shell, and the fourth connecting hole is used for a fastener to pass through and connect to the hard disk. The first side wall is the side wall of the cover shell opposite to the first reinforcing rib.

[0028] In an optional embodiment, an avoidance notch is provided on the second side wall of the cover shell, the second side wall is arranged on the side of the first reinforcing rib away from the mounting groove, and the avoidance notch is arranged opposite to the fourth connecting hole on the first reinforcing rib.

[0029] Beneficial effect: The avoidance gap allows a tool such as a screwdriver to pass through, thereby driving the fastener through the first reinforcing rib, thereby connecting the hard disk to the adapter bracket. On this basis, the avoidance gap can also save the material required for the adapter bracket, thereby reducing the weight of the adapter bracket and saving the cost of the adapter bracket.

[0030] In an optional embodiment, a ventilation hole is formed on a side of the adapter bracket away from the adapter plate.

[0031] Beneficial effects:

[0032] A hard disk generates a lot of heat when it is working. If it is not discharged in time, the temperature of the hard disk will rise, affecting the stability and life of the hard disk. The adapter bracket of the embodiment of the present invention has a vent on the side away from the adapter plate, which can effectively improve the heat dissipation performance of the hard disk. A good vent design can enable the heat generated by the hard disk during operation to be discharged in time, avoiding performance degradation or data loss due to excessive temperature.

[0033] In an optional embodiment, the adapter bracket further includes:

[0034] A ventilation groove is provided on one side surface of the cover shell along the thickness direction, and ventilation openings are provided on at least two side groove walls of the ventilation groove along the length direction of the cover shell;

[0035] The second reinforcing rib is arranged in the ventilation groove and extends along the length direction of the hard disk. The second reinforcing rib is connected between the groove walls on two opposite sides of the ventilation groove.

[0036] Beneficial effects:

[0037] Through such an arrangement, the ventilation groove is located at the end of the adapter bracket away from the adapter plate, which not only helps to increase the area of ​​the ventilation port to improve the heat dissipation effect of the hard disk, but also the groove wall of the ventilation groove can be combined with the first reinforcement rib to form an installation groove that can match and accommodate the hard disk. On this basis, the second reinforcement rib is arranged in the ventilation groove and extends along the length direction of the hard disk, which can improve the structural strength of the adapter bracket without blocking the ventilation at the ventilation port.

[0038] In an optional embodiment, the adapter bracket is provided with a fifth connection hole, and the hard disk bracket is correspondingly provided with a sixth connection hole, and the fifth connection hole and the sixth connection hole can be used for the fastener to pass through in sequence and connect the hard disk bracket and the adapter bracket, and the fifth connection hole includes:

[0039] A through hole is formed on the adapter bracket;

[0040] An annular protrusion is arranged around the through hole;

[0041] The hot melt nut is arranged in the annular convex portion and is coaxially arranged with the through hole.

[0042] Beneficial effects: The hot melt nut can be used to cooperate with the fastener to increase the connection strength between the adapter bracket and the hard disk bracket, thereby making the connection between the adapter bracket and the hard disk bracket more reliable. The annular protrusion can increase the hot melt contact part of the hot melt nut to prevent the hot melt nut from falling off.

[0043] In a second aspect, the present invention further provides a server, comprising:

[0044] A chassis, wherein a hard disk frame is provided inside the chassis;

[0045] The hard disk module provided by the second invention of the present invention is arranged in the hard disk frame.

[0046] Beneficial effects:

[0047] The server of the second aspect of the present invention includes or uses the hard disk module of the first aspect of the present invention, and thus has its beneficial effect, namely, two hard disks can be arranged in one hard disk tray, and the connection between the hard disk and the hard disk backplane can be achieved through an adapter plate, thereby enabling each hard disk tray and hard disk frame to accommodate two hard disks while maintaining the original system architecture, thereby achieving capacity expansion of the hard disk system without changing the structure at the front window of the chassis (namely, the hard disk frame and the hard disk backplane), thereby significantly expanding the capacity of the storage system without increasing the R&D cost of the server.

[0048] Since the server of the embodiment of the present invention does not need to adjust the original architecture of the server, it can reduce the potential risks caused by the transformation and improve the stability of the system. The hard disk module of the embodiment of the present invention has good scalability and can easily add more hard disks as needed to meet the growing storage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0067] like Figure 1 As shown, in the related art, when installing a 3.5-inch hard disk 102', a 3.5-inch hard disk 102' is installed in each hard disk bracket 101', and connection holes 2' are respectively provided on both sides of the hard disk bracket 101'. During the installation process, fasteners are used to pass through the connection holes 2' to connect the hard disk 102' to fix the hard disk 102' on the hard disk bracket 101'. The hard disk 102' is fixed on the adapter bracket 104', and then fasteners are used to pass through the connection holes to connect the hard disk bracket 101' and the adapter bracket 104'. Each hard disk bracket 101' can only install one hard disk 102'.

[0068] Therefore, in the related art, only one hard disk 102' can be set in each hard disk bracket 101', and only one hard disk module 1' can be installed in each hard disk 102' slot of the server chassis. Therefore, the storage capacity expansion of the hard disk 102' is often accompanied by an increase in the space occupied by the hard disk 102', and it is necessary to purchase new servers, adopt a new system architecture, and even upgrade a new computer room, resulting in an increase in R&D costs.

[0069] Combine the following Figures 1 to 10 , describing an embodiment of the present invention.

[0070] According to an embodiment of the present invention, on the one hand, a hard disk module 1 is provided, comprising a hard disk bracket 101, at least two hard disks 102 and an adapter board 103. Among them, at least two hard disks 102 are stacked along the thickness direction of the hard disk 102 and are arranged in the hard disk bracket 101. The adapter board 103 comprises a first connector 1031, a second connector 1032 and a card body 1033. The first connector 1031 is on a side surface of the card body 1033. An integrated circuit is formed on the card body 1033. The input end of the integrated circuit is connected to the first connector 1031. The integrated circuit can convert the signal input from the hard disk backplane into at least two signals. There are at least two second connectors 1032, which are arranged on the other side surface of the card body 1033 and connected to the output end of the integrated circuit. Each second connector 1032 is used to connect a hard disk 102.

[0071] The hard disk module 1 of the embodiment of the present invention includes an adapter plate 103, and a first connector 1031 on one side of the adapter plate 103 can receive a signal input from the hard disk backplane. The integrated circuit on the adapter plate 103 can convert the signal input from the hard disk backplane into at least two signals. Through such a configuration, the hard disk module of the embodiment of the present invention uses a clever internal structure design of the hard disk bracket so that each hard disk slot can accommodate two hard disks, and the connection between the hard disk 102 and the hard disk backplane is realized through the adapter plate 103, thereby enabling each hard disk bracket 101 and hard disk frame to accommodate two hard disks 102 on the basis of the original system architecture unchanged, thereby realizing the expansion of the hard disk system without changing the structure at the front window of the chassis (i.e., the hard disk frame and the hard disk backplane), thereby significantly expanding the capacity of the storage system without increasing the R&D cost of the server, and greatly improving the space utilization rate in the hard disk module 1, so that the original server hard disk 102 installation slot is doubled.

[0072] Furthermore, since the hard disk module 1 of the embodiment of the present invention does not need to adjust the original architecture of the server, it can reduce the potential risks caused by the transformation and improve the stability of the system. The hard disk module 1 of the embodiment of the present invention has good scalability and can easily add more hard disks 102 as needed to meet the growing storage needs.

[0073] In addition, by distributing data on two hard disks 102, the data reading and writing speed can be improved, and data backup can be provided when a hard disk fails.

[0074] It should be noted that in the embodiment of the present application, there is no limitation on the size of the hard disk 102 . For example, in an optional embodiment, the hard disk 102 is an ultra-thin 2.5-inch hard disk 102 , so that two hard disks 102 can be stacked in a hard disk tray 101 .

[0075] As a convertible implementation, the hard disk 102 may also be an ultra-thin 3.5-inch hard disk 102. In this case, no adapter bracket is provided in the hard disk module 1, and the ultra-thin 3.5-inch hard disk 102 is directly connected to the hard disk bracket.

[0076] In one embodiment, the board body of the adapter board 103 is preferably, but not limited to, a PCB (Printed Circuit Board). The PCB can adapt to two hard disks 102 to implement data read and write operations without making major changes to the existing system. The first connector 1031 and the second connector 1032 can be optionally connected to the board body by welding. As a convertible embodiment, the first connector 1031 and the second connector 1032 can also be optionally connected to the board body by means of crimping or bonding.

[0077] In one embodiment, the first connector 1031 is a male connector, and the second connector 1032 is a female connector.

[0078] In one embodiment, Figure 5 As shown, the hard disk module 1 further includes an adapter bracket 104 for connecting to the hard disk bracket 101, and the adapter bracket 104 is provided with a mounting slot 1041 and an escape opening 1042. At least two hard disks 102 are arranged in the mounting slot 1041, the adapter plate 103 is connected to one end of the adapter bracket 104, and the second connector 1032 can pass through the escape opening 1042 to connect to the hard disk 102.

[0079] By such arrangement, the adapter bracket 104 can be used to limit the hard disk 102 and install the adapter plate 103. During the assembly process, the operator can first install the adapter plate 103 at one end of the adapter bracket 104, install the hard disk 102 into the installation slot 1041 of the adapter bracket 104, and make the hard disk 102 plug into the second connector 1032 of the adapter bracket 104, then fix the adapter plate to the adapter bracket 104, and finally connect the adapter bracket 104 to the hard disk bracket 101.

[0080] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0081] As a convertible implementation, in an embodiment not shown in the drawings, the hard disk 102 may also be directly connected to the hard disk bracket 101 .

[0082] In one embodiment, Figure 6 As shown, the adapter bracket 104 is provided with a first connection structure 1043. Fig. 9 and Fig.10 As shown, a second connection structure 1034 is provided on the adapter plate 103 , and the first connection structure 1043 can be detachably connected to the second connection structure 1034 .

[0083] The adapter plate 103 is detachably connected to the adapter bracket 104, so that the adapter plate 103 can be easily replaced when a failure occurs in the adapter plate 103, so that the adapter bracket 104 can be reused.

[0084] As a convertible implementation, the adapter plate 103 can be fixedly connected to the adapter bracket 104. For example, the adapter plate 103 can be connected to the adapter bracket 104 by welding or bonding.

[0085] In one embodiment, Figure 6As shown, the first connection structure 1043 includes a first connection hole 10431 and a limiting member 10432 .

[0086] The first connection hole 10431 is provided at one end of the avoidance opening 1042. The stopper 10432 is provided at the other end of the avoidance opening 1042, and includes a connection section and a clamping head connected in sequence in a direction away from the hard disk 102. The stopper 10432 and the first connection hole 10431 are spaced apart in the thickness direction of the hard disk 102, and the cross-sectional area of ​​the connection section is smaller than the cross-sectional area of ​​the clamping head;

[0087] like Fig. 9 As shown, the second connection structure 1034 includes a second connection hole 10341 and a third connection hole 10342. The first connection hole 10431 and the stopper 10432 are respectively arranged on both sides of the avoidance opening 1042 and are spaced apart along the thickness direction of the hard disk 102. The stopper 10432 includes a connection section and a clamping head which are sequentially connected in a direction away from the hard disk 102.

[0088] The second connection structure 1034 includes a second connection hole 10341 and a third connection hole 10342. The second connection hole 10341 can allow a fastener to pass through and connect to the first connection hole 10431. The third connection hole 10342 and the second connection hole 10341 are arranged at intervals. The third connection hole 10342 has a first hole section and a second hole section. The first hole section and the second hole section are connected to each other. The area of ​​the first hole section is larger than the cross-sectional area of ​​the clamp head and can allow the limiter 10432 to pass through. The area of ​​the second hole section is larger than the cross-sectional area of ​​the connection section and smaller than the cross-sectional area of ​​the clamp head. The limiter 10432 can enter from the first hole section into the second hole section and limit the adapter plate 103 on the adapter bracket 104 when in the second hole section.

[0089] When the adapter plate 103 needs to be connected to the adapter bracket 104, the operator can first pass the limiting member 10432 through the first hole section of the third connection hole 10342, then move the adapter plate 103, and insert the limiting member 10432 into the second hole section of the third connection hole 10342 to pre-position the adapter plate 103 on the limiting member 10432, and finally pass the fastener through the second connection hole 10341 and the first connection hole 10431, so as to lock the adapter plate 103 on the adapter bracket 104. In addition, since the second connection hole 10341 and the third connection hole 10342 are diagonally distributed on the adapter plate 103, the left-right balance can be ensured during the process of disassembling and installing the hard disk 102.

[0090] In one embodiment, the stopper 10432 may be an I-shaped nail. The I-shaped nail may be crimped on the adapter bracket 104. As a convertible embodiment, the I-shaped nail may also be installed on the adapter bracket 104 by bonding or hot-melt connection. The fastener is preferably not limited to a bolt or a rivet. For example, in a preferred embodiment, the fastener may be an M3 screw.

[0091] As a convertible implementation, the adapter plate 103 may also be connected to the adapter bracket 104 by means of clamping, riveting or bonding.

[0092] As another convertible implementation, in an embodiment not shown in the accompanying drawings, a guide structure may be optionally provided between the adapter plate 103 and the adapter bracket 104. The adapter plate 103 can enable the second connector 1032 to be plugged into the hard disk 102 under the guidance of the guide structure. This not only avoids damage to the second connector 1032 or the hard disk 102 during the plug-in process, but the guide structure can also take on part of the torque instead of the second connector 1032 and the hard disk 102.

[0093] The guide structure preferably includes, but is not limited to, the cooperation of a guide protrusion and a guide groove.

[0094] As another convertible implementation, the adapter plate 103 can be connected to the adapter bracket 104 along the plugging direction of the second connector 1032 and the hard disk 102. By so configuring, during the assembly process, the hard disk 102 can be first installed on the adapter bracket 104, and then the operator can install the adapter plate 103 on the adapter bracket 104 along the plugging direction of the second connector 1032 and the hard disk 102, and simultaneously complete the connection between the hard disk 102 and the second connector 1032. At this time, the first connector 1031 and the second connector 1032 are preferably, but not limited to, a snap-on assembly, a riveted assembly, or a bolted assembly.

[0095] In one embodiment, Figure 8 As shown, the adapter bracket 104 includes a housing 1044 and a first reinforcing rib 1045. The housing 1044 is used to connect the hard disk bracket. The first reinforcing rib 1045 is arranged in the housing 1044 and extends along the length direction of the hard disk 102. The mounting groove 1041 is formed between the first reinforcing rib 1045 and a side wall of the housing 1044.

[0096] By so configuring, the first reinforcing rib 1045 can not only be used to separate the mounting slot 1041 in the housing 1044 for accommodating the hard disk 102, but also can improve the structural strength of the housing 1044. When the adapter bracket 104 is a plastic part, the first reinforcing rib 1045 can also facilitate demoulding of the adapter bracket 104.

[0097] In one embodiment, a fourth connection hole 1046 is respectively provided on the first reinforcing rib 1045 and the first side wall of the cover shell 1044 , and the fourth connection hole 1046 is used for fasteners to pass through and connect to the hard disk 102 . The first side wall is the side wall of the cover shell 1044 opposite to the first reinforcing rib 1045 .

[0098] The fourth connection hole 1046 is used to position the hard disk 102 on the adapter bracket 104 .

[0099] The fourth connection holes 1046 preferably include two groups, and the two groups of fourth connection holes 1046 are arranged at intervals along the thickness direction of the hard disk 102 , and each group of fourth connection holes 1046 can be used to connect to one hard disk 102 .

[0100] The fastener is preferably not limited to being a bolt or a rivet, etc. Exemplarily, in a preferred embodiment, the fastener may be an M3 screw.

[0101] As a convertible implementation, the fourth connection holes may also be selected as a group and provided at the notch of the mounting slot 1041 , and can be connected to the outer hard disk 102 to prevent the hard disk 102 from falling out.

[0102] As a convertible implementation, in an embodiment not shown, the hard disk 102 can also be optionally installed on the cover 1044 by means of snap-on, riveting or bonding.

[0103] In one embodiment, a connecting groove recessed toward the mounting groove 1041 is respectively formed on the first side wall of the cover shell 1044 and the first reinforcing rib 1045 , and the fourth connecting hole 1046 is disposed in the connecting groove.

[0104] In one embodiment, Figure 6 and Figure 8 As shown, a second side wall of the cover shell 1044 is provided with an avoidance notch 1047 . The second side wall is provided on a side of the first reinforcing rib 1045 away from the mounting groove 1041 . The avoidance notch 1047 is arranged opposite to the fourth connecting hole 1046 on the first reinforcing rib 1045 .

[0105] The avoidance gap 1047 allows a tool such as a screwdriver to pass through, thereby driving the fastener through the first reinforcing rib 1045, thereby connecting the hard disk 102 to the adapter bracket 104. On this basis, the avoidance gap can also save the material required for the adapter bracket, thereby reducing the weight of the adapter bracket and saving the cost of the adapter bracket.

[0106] The avoidance notch 1047 is preferably set to open on the same side as the installation slot, so as to facilitate demoulding of the adapter bracket 104. The fastener is preferably not limited to bolts or rivets. For example, in a preferred embodiment, the fastener can be an M3 screw.

[0107] As a convertible implementation, the avoidance gap 1047 can also be selected as a through hole formed in the middle of the second side wall.

[0108] In one embodiment, a material-reducing groove is formed between the second side wall and the reinforcing rib, and the material-reducing groove helps to simplify the material required for the adapter bracket 104 and reduce the overall weight of the hard disk module 1 .

[0109] As a convertible implementation, in an embodiment not shown in the accompanying drawings, ventilation holes 1048 may be optionally provided on the groove walls on both sides of the subtractive groove along the length direction of the hard disk 102, and heat sinking fins may be optionally provided in the subtractive groove. The heat sinking fins are preferably offset from the first reinforcement ribs 1045. The heat generated by the hard disk 102 during operation can be conducted to the heat sinking fins through the first reinforcement ribs 1045. The airflow can enter the subtractive groove from the ventilation holes 1048 at one end of the subtractive groove, and the heat carried by the heat sinking fins is discharged outward from the ventilation holes 1048 at the other end of the subtractive groove, thereby improving the heat dissipation effect of the hard disk module 1.

[0110] In a preferred embodiment, a ventilation hole 1048 is formed on a side of the adapter bracket 104 away from the adapter plate 103 .

[0111] The hard disk 102 generates a large amount of heat when working. If it is not discharged in time, the temperature of the hard disk 102 will rise, affecting the stability and life of the hard disk 102. The adapter bracket 104 of the embodiment of the present invention has a vent 1048 on the side away from the adapter plate 103, which can effectively improve the heat dissipation performance of the hard disk 102. A good design of the vent 1048 can enable the heat generated by the hard disk 102 during operation to be discharged in time, avoiding performance degradation or data loss due to excessive temperature.

[0112] In a preferred embodiment, Figure 7 As shown, the adapter bracket 104 further includes a ventilation groove 1049 and a second reinforcing rib. The ventilation groove 1049 is provided on one side surface of the housing 1044 along the thickness direction, and the ventilation groove 1049 is provided with ventilation openings 1048 on at least two side groove walls along the length direction of the housing 1044. The second reinforcing rib is provided in the ventilation groove 1049 and extends along the length direction of the hard disk 102, and the second reinforcing rib is connected between two side groove walls of the ventilation groove 1049 that are opposite to each other.

[0113] Through such a configuration, the ventilation groove 1049 is located at the end of the adapter bracket 104 away from the adapter plate 103, which not only helps to increase the area of ​​the ventilation port 1048 to enhance the heat dissipation effect of the hard disk 102, but also the groove wall of the ventilation groove 1049 can also be combined with the first reinforcement rib 1045 to form an installation groove 1041 that can match and accommodate the hard disk 102. On this basis, the second reinforcement rib is arranged in the ventilation groove 1049 and extends along the length direction of the hard disk 102, which can enhance the structural strength of the adapter bracket 104 without blocking the ventilation at the ventilation port 1048.

[0114] In one embodiment, a plurality of material reduction holes are further provided on a surface of the cover 1044 on one side along the thickness direction of the hard disk 102 .

[0115] In one embodiment, the adapter bracket 104 is provided with a fifth connection hole 10410. The hard disk bracket 101 is correspondingly provided with a sixth connection hole, and the fifth connection hole 10410 and the sixth connection hole can allow fasteners to pass through and connect the hard disk bracket 101 and the adapter bracket 104 in sequence, and the fifth connection hole 10410 includes a through hole, an annular protrusion and a hot melt nut. The hot melt nut is formed on the adapter bracket 104. The annular protrusion is arranged around the outside of the through hole. The hot melt nut is arranged in the annular protrusion and is coaxial with the through hole.

[0116] The hot melt nut can be used to cooperate with the fastener to increase the connection strength between the adapter bracket 104 and the hard disk bracket 101, thereby making the connection between the adapter bracket 104 and the hard disk bracket 101 more reliable. The annular protrusion can increase the hot melt contact portion of the hot melt nut to prevent the hot melt nut from falling off. The fastener is preferably not limited to a bolt or a rivet. For example, in a preferred embodiment, the fastener can be an M3 screw.

[0117] According to an embodiment of the present invention, on the other hand, a server is provided, comprising a chassis and a hard disk module 1. The chassis is provided with a hard disk frame. The hard disk module 1 is provided in the hard disk frame.

[0118] The hard disk enclosure is a device used to store hard disks in the server. It can be used to fix and protect hard disks. The design of the hard disk enclosure usually takes into account factors such as the size of the hard disk, the interface type, the heat dissipation performance, and the installation method. There are many types of hard disk enclosures, including but not limited to 2.5-inch and 3.5-inch specifications, and a variety of different interface types, such as SATA, USB, etc.

[0119] The server of the second aspect of the present invention includes or uses the hard disk module 1 of the first aspect of the present invention, and thus has its beneficial effect, namely, two hard disks 102 can be arranged in one hard disk bracket, and the connection between the hard disk 102 and the hard disk backplane can be realized through the adapter plate 103, thereby enabling each hard disk bracket 101 and hard disk frame to accommodate two hard disks 102 on the basis of the original system architecture unchanged, thereby realizing the expansion of the hard disk system without changing the structure at the front window of the chassis (namely the hard disk frame and the hard disk backplane), thereby significantly expanding the capacity of the storage system without increasing the research and development cost of the server.

[0120] Since the server of the embodiment of the present invention does not need to adjust the original architecture of the server, it can reduce the potential risks caused by the transformation and improve the stability of the system. The hard disk module 1 of the embodiment of the present invention has good scalability and can easily add more hard disks 102 as needed to meet the growing storage demand.

[0121] In summary, the hard disk module 1 of the first aspect and the server of the second aspect of the embodiment of the present invention have the following advantages:

[0122] The hard disk module 1 and hard disk bracket of the embodiment of the present application are suitable for meeting the growing storage demand under the original system architecture without upgrading the server room or changing the original server structure. Only the adapter bracket 104 needs to be installed on the original hard disk bracket 101.

[0123] This achieves efficient storage expansion from a single disk to a dual disk. In the related art, the storage expansion of the hard disk 102 is often achieved by purchasing new servers and adopting new system architectures to meet the needs. However, such expansion methods often require the addition of new servers, resulting in an increase in occupied space, which often requires the upgrade of the server room, and further requires more R&D costs to develop new architectures.

[0124] A hard disk module 1 and a server in the embodiment of the present application can expand a single hard disk 102 slot on the original server into two 2.5-inch hard disk 102 installation slots by using a hard disk 102 adapter bracket 104 without changing the original system architecture and the server layout of the computer room, which is conducive to the continuation of system hardware equipment. It reduces the upgrade cost of additional server equipment and has high application value.

[0125] It should be noted that in this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0126] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician in the field can easily make changes or variations within the technical scope disclosed in the present invention, and such changes or variations should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims. As long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
