[0058] An embodiment of the present application provides a hard disk backplane assembly, and the hard disk backplane assembly of the present application is described in detail below with reference to the accompanying drawings.

[0059] Reference Figure 1 , showing a schematic diagram of the structure of a hard disk backplane assembly provided in an embodiment of the present application, referring to Figure 2 , shows a schematic diagram of the assembly of a backplane and a tray of a hard disk backplane assembly provided in an embodiment of the present application, with reference to Figure 3 , shows a schematic diagram of the structure of a backplane of a hard disk backplane assembly provided in an embodiment of the present application, referring to Figure 4 , showing Figure 3 A partial enlarged view of the A position in the middle, refer to Figures 5 to 7 , showing a structural schematic diagram of a tray of a hard disk backplane assembly provided in an embodiment of the present application, referring to Figure 8 , showing Figure 6 A partial enlarged view of position B in the middle, refer to Figures 9 and 10 , showing a schematic diagram of the structure of a fixing plate of a hard disk backplane assembly provided by an embodiment of the present application, referring to Fig.11 , shows a logical topology diagram of a hard disk backplane assembly provided by an embodiment of the present application. It should be noted that, for ease of understanding, the drawings of the embodiment of the present application schematically separate the first straight section 131, the second straight section 132 and the rounded section 133 with dotted lines.

[0060] like Figures 1 to 4 As shown, the present application provides a hard disk backplane assembly, comprising: a plurality of independent backplanes 1; the backplane 1 comprises a main body 11 and a plurality of hard disk connectors 12 arranged on the main body 11, the hard disk connector 12 being used to connect the hard disk; wherein the main body 11 is provided with at least one L-shaped shock absorbing hole 13 in the circumferential direction of the hard disk connector 12, the L-shaped shock absorbing hole 13 being used to absorb external vibration impact.

[0061] In the embodiment of the present application, since a plurality of independent backplanes 1 are provided, when one of the backplanes 1 fails, it will not affect other backplanes 1, thereby reducing the failure domain of the hard disk backplane assembly and improving the working reliability of the server. More importantly, when the hard disk is connected to the hard disk connector 12, an L-shaped shock absorbing hole 13 is provided around the hard disk connector 12. In this way, the rigidity of the body 11 around the hard disk connector 12 can be reduced. When the external vibration impact is transmitted to the L-shaped shock absorbing hole 13, the body 11 located around the L-shaped shock absorbing hole 13 can be partially deformed to absorb the external vibration impact, thereby greatly reducing the interference of the external vibration on the hard disk, which is beneficial to improving the working reliability of the hard disk. In addition, the L-shaped shock absorbing hole 13 can also play a role in ventilation and heat dissipation, which is beneficial to improving the heat dissipation effect of the hard disk.

[0062] It should be noted that the embodiments of the present application do not limit the number of backplanes 1 and the number of hard disk connectors 12 on a single backplane 1, and those skilled in the art can adjust them according to actual needs. In the related art, a backplane 1 is provided with 105 hard disk connectors 12, that is, the backplane 1 can simultaneously install 105 hard disks. When the backplane 1 fails, all 105 hard disks need to be unplugged from the backplane 1 before the backplane 1 can be maintained. In one embodiment, Figure 1 As shown, the hard disk backplane assembly includes three backplanes 1, that is, the backplane 1 of the related art is divided into three. The number of hard disk connectors 12 on each backplane 1 is 35, and 35 hard disks can be installed at the same time. When one of the hard disks fails, it is only necessary to unplug the 35 hard disks installed on the backplane 1 to maintain the backplane 1. In this process, the remaining backplanes 1 can work normally, thereby reducing the failure domain of the hard disk backplane assembly and improving the working reliability of the server.

[0063] In some optional embodiments of the present application, the L-shaped shock-absorbing hole 13 includes: a first straight section 131, a second straight section 132 and a rounded section 133; the first straight section 131 and the second straight section 132 are respectively arranged on two adjacent sides of the hard disk connector 12, and the rounded section 133 is arranged between the first straight section 131 and the second straight section 132 to connect the first straight section 131 and the second straight section 132.

[0064] In the embodiment of the present application, since the first straight section 131 and the second straight section 132 are arranged on two adjacent sides of the hard disk connector 12, the body 11 on the adjacent two sides of the hard disk connector 12 can be partially deformed, that is, the L-shaped shock-absorbing hole 13 can absorb vibration impacts in more directions, thereby further reducing the interference of external vibrations on the hard disk. In addition, since the rounded section 133 is provided and the rounded section 133 is arranged between the first straight section 131 and the second straight section 132, the stress can be effectively dispersed to avoid stress concentration in the area between the first straight section 131 and the second straight section 132, which is conducive to improving the overall stability of the L-shaped shock-absorbing hole 13, so that it can better play a shock-absorbing role.

[0065] It should be noted that the embodiment of the present application does not limit the number of L-shaped shock-absorbing holes 13, and those skilled in the art can adjust it according to actual needs. In one embodiment, for the hard disk connector 12 located at the edge area of ​​the back plate 1, Figure 2 As shown in the first and fifth rows of hard disk connectors 12, due to the lack of space around the hard disk backplane 1 connector, only one L-shaped shock absorbing hole 13 may be provided, and the L-shaped shock absorbing hole 13 is provided on one side of the hard disk connector 12 close to the center of the backplane 1. In another embodiment, for the hard disk connector 12 located in the middle area of ​​the backplane 1, as shown in FIG. Figure 2 As shown in the second to fourth rows of hard disk connectors 12, since there is sufficient space around the hard disk connectors 12, two L-shaped shock absorbing holes 13 can be provided, and the two L-shaped shock absorbing holes 13 are symmetrical with respect to the center line of the hard disk connector 12. In this way, the body 11 around the hard disk connector 12 can be partially deformed, so that the L-shaped shock absorbing holes 13 absorb external vibration impacts as comprehensively as possible, which is conducive to further reducing the interference of external vibration on the hard disk.

[0066] In practical applications, the hard disk connector 12 provided on the backplane 1 is usually an SFF 8639 connector. When the SFF 8639 connector is installed on the backplane 1, its projection size perpendicular to the backplane 1 is approximately 46mm×6mm. The distance between the L-shaped shock-absorbing hole 13 and the hard disk connector 12 determines the shock-absorbing effect and the structural strength of the body 11 around the hard disk connector 12. Based on this, in some optional embodiments of the present application, the first straight section 131 is extended along the length direction of the hard disk connector 12, and the first straight section 131 includes a first hole wall 1311 away from the hard disk connector 12, and the distance between the first hole wall 1311 and the center of the hard disk connector 12 is 8mm-11mm. For example, the distance between the first hole wall 1311 and the center of the hard disk connector 12 can be 8mm, 8.2mm, 9.5mm, 10.8mm, 11mm or other values. The second straight section 132 is extended along the width direction of the hard disk connector 12. The second straight section 132 includes a second hole wall 1321 away from the hard disk connector 12. The distance between the second hole wall 1321 and the center of the hard disk connector 12 is 29mm-35mm. For example, the distance between the second hole wall 1321 and the center of the hard disk connector 12 can be 29mm, 29.35mm, 32mm, 34.5mm, 35mm or other values. In this way, by limiting the distance between the first hole wall 1311 of the first straight section 131, the second hole wall 1321 of the second straight section 132 and the center of the hard disk connector 12, the rigidity of the body 11 around the hard disk connector 12 can be effectively reduced, and the vibration can be promptly responded to through the local deformation of the body 11, thereby improving the shock absorption effect.

[0067] In one embodiment, in the case where two L-shaped shock absorbing holes 13 are provided, the spacing between the first hole walls 1311 of the two L-shaped shock absorbing holes 13 is 16.4 mm, that is, the spacing between one of the first hole walls 1311 and the center of the hard disk connector 12 is 8.2 mm. The spacing between the second hole walls 1321 of the two L-shaped shock absorbing holes 13 is 58.7 mm, that is, the spacing between one of the second hole walls 1321 and the center of the hard disk connector 12 is 29.35 mm.

[0068] In practical applications, the shock absorbing effect of the L-shaped shock absorbing hole 13 is closely related to the size of the opening. Based on this, in some optional embodiments of the present application, the opening width of the L-shaped shock absorbing hole 13 is 1-2 times the thickness of the body 11. For example, the opening width of the L-shaped shock absorbing hole 13 is 1 times, 1.2 times, 1.5 times, 1.7 times, 2 times or other values ​​of the thickness of the body 11. On the one hand, the deformation degree of the body 11 around the L-shaped shock absorbing hole 13 can be increased, thereby improving the shock absorbing effect. On the other hand, the processing difficulty of the L-shaped shock absorbing hole 13 can be reduced, which is conducive to reducing the processing cost of the hard disk backplane assembly.

[0069] Since the body 11 around the hard disk connector 12 also needs to meet the wiring requirements, there is often a contradiction between the wiring and the setting of the L-shaped shock-absorbing hole 13. Based on this, in some optional embodiments of the present application, the length of the first straight section 131 is 35mm-40mm, and the length of the second straight section 132 is 2.5mm-5mm. For example, the length of the first straight section 131 can be 35mm, 36.5mm, 37.7mm, 38mm, 40mm or other values; the length of the second straight section 132 can be 2.5mm, 3mm, 3.6mm, 4.2mm, 5mm or other values. In this way, the length of the L-shaped shock-absorbing hole 13 can be increased as much as possible on the basis of meeting the wiring requirements, so that the L-shaped shock-absorbing hole 13 covers as much area as possible on the circumference of the hard disk connector 12, which is conducive to further improving the shock absorption effect. In addition, the rounded section 133 includes an arc-shaped hole wall away from the hard disk connector 12, and the radius of the arc-shaped hole wall is 5mm-10mm. For example, the radius of the arc-shaped hole wall can be 5mm, 6.5mm, 7.7mm, 9.2mm, 10mm or other values. By setting a rounded section 133 with a larger radius, not only can the first straight section 131 and the second straight section 132 have a smooth transition, which is beneficial to improving the structural stability of the L-shaped shock-absorbing hole 13. It can also reduce the internal stress generated during the processing of the back plate 1 and prevent the back plate 1 from cracking due to residual stress. In one embodiment, the total length of the L-shaped shock-absorbing hole 13 along the length direction of the hard disk connector 12 (that is, the sum of the lengths of the first straight section 131 and the rounded section 133 along the length direction of the connector) is 44.2mm, and the radius of the arc-shaped hole wall is 6.5mm.

[0070] In some optional embodiments of the present application, the hard disk backplane assembly is suitable for being installed in a chassis of a server (not shown in the drawings), and the hard disk backplane assembly further comprises: a plurality of trays 2 and a locking mechanism 3; the plurality of trays 2 are arranged at intervals along a first direction X and are suitable for being movably connected to the chassis; a backplane 1 is detachably connected to a tray 2; the locking mechanism 3 is arranged on a side of the tray 2 away from the backplane 1 and is at least partially used for connecting to the chassis, and the locking mechanism 3 has a locked state and an unlocked state, in which the tray 2 is confined in the chassis in the locked state, and in the unlocked state, the limit on the tray 2 is released so that the tray 2 can move relative to the chassis.

[0071] In the embodiment of the present application, since the back panel 1 is detachably connected to the tray 2, the back panel 1 can be conveniently disassembled and assembled, thereby improving the maintenance convenience of the back panel 1. In addition, since a locking mechanism 3 is provided, and the locking mechanism 3 has a locked state and an unlocked state. In this way, when there is no failure in the back panel 1, the locking mechanism 3 is in a locked state, so that the tray 2 is reliably confined in the chassis. In the event of a failure in the back panel 1, the corresponding locking mechanism 3 can be switched to an unlocked state, so that the tray 2 can move relative to the chassis, so that the back panel 1 can be subsequently disassembled for maintenance.

[0072] It should be noted that the backplane 1, tray 2 and locking mechanism 3 of the embodiment of the present application correspond one to one, and the three form a functionally independent unit, which can realize the disassembly, assembly and maintenance of a single backplane 1. In this way, when one of the backplanes 1 fails and needs maintenance, it is only necessary to pull out the tray 2 installed with the corresponding backplane 1 from the front window, without the need to remove it from the shelf, and it will not affect the normal operation of other backplanes 1 and the hard disks installed thereon, that is, other backplanes 1 are conducive to improving the working reliability of the server. In addition, the embodiment of the present application does not limit the detachable connection method between the tray 2 and the backplane 1, and those skilled in the art can adjust it according to actual needs. In one of the embodiments, a step I-shaped nail is provided on the side of the tray 2 close to the backplane 1, and a gourd hole is provided on the backplane 1 at the corresponding position of the step I-shaped nail, and the step I-shaped nail is connected with the gourd hole. This detachable connection method has the advantages of convenient installation, stable structure and convenient maintenance. It is a common tool-free installation structure, which is conducive to improving the efficient and convenient disassembly and assembly of the backplane 1. In addition, the hard disk backplane assembly can also be provided with nut columns, and the backplane 1 and the tray 2 are respectively provided with threaded holes at corresponding positions. The threaded cooperation between the nut columns and the threaded holes can further improve the fixing reliability of the tray 2 and the backplane 1.

[0073] In some optional embodiments of the present application, the locking mechanism 3 includes: a limit column 31, a first clamping member 32 and a second clamping member 33 arranged in sequence along a first direction X; the limit column 31 is used to be fixedly connected to the chassis; the first clamping member 32 and the second clamping member 33 are both rotatably connected to the tray 2, and the first clamping member 32 has a first end and a second end arranged away from each other, the first end is used to be connected to the limit column 31, and the second end is used to be connected to the second clamping member 33; in the locked state, the second end is connected to the second clamping member 33, and the first end is connected to the limit column 31 to limit the tray 2, and in the unlocked state, the second end is disconnected from the second clamping member 33, and the first end is disconnected from the limit column 31 to release the limitation of the tray 2.

[0074] In the embodiment of the present application, the first clamping member 32 and the second clamping member 33 are provided, and both are rotatably connected to the tray 2. Thus, in the locked state, the second end of the first clamping member 32 is connected to the second clamping member 33, so that the first end of the first clamping member 32 is reliably connected to the limiting column 31, thereby reliably limiting the position of the tray 2. In the unlocked state, the second end of the first clamping member 32 is disconnected from the second clamping member 33, and the first clamping member 32 can be rotated relative to the tray 2, so that the first end of the first clamping member 32 is disconnected from the limiting column 31, thereby releasing the limiting of the tray 2, and applying a force to the first clamping member 32 can remove the tray 2 from the chassis.

[0075] It should be noted that, in order to keep the first clamping member 32 and the second clamping member 33 connected, the locking mechanism 3 further includes a tension spring and a torsion spring.
