Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a backplane assembly and a computing device. Background Art

[0002] In a server, a hard drive backplane connects the hard drives to the motherboard. To accommodate more hard drives and increase storage space, a standardized hard drive space design can be used. This means the server's hard drive rack can be divided into multiple compartments. Each compartment can accommodate an equal number of hard drives, for example, eight hard drives. Each backplane can connect to eight hard drives, creating an eight-drive backplane.

[0003] The size of the existing 8-disk backplane is much larger than the size of the compartment for installing 8 hard disks, which cannot fully utilize the installation space and is not conducive to achieving modular design. Summary of the Invention

[0004] The present application provides a backplane assembly and a computing device. The backplane of the backplane assembly is installed on a partition through an adapter. The backplane can correspond to the compartment formed by the two partitions, which facilitates full utilization of the backplane installation space and helps to achieve modular design.

[0005] In the first aspect, the present application provides a backplane assembly, which includes: at least two adapters arranged at intervals, each adapter including a base, two adjacent bases being used to be installed on different partitions of a hard disk rack, and at least one of the two adjacent bases is provided with a first connecting structure, and at least the other of the two adjacent bases is provided with a second connecting structure; at least one backplane, a first side of the backplane is provided with a first fixing structure, and a second side of the backplane arranged opposite to the first side is provided with a second fixing structure; wherein the first side of the backplane corresponds to one of the two adjacent bases, and the first fixing structure is connected to the first connecting structure, the second side of the backplane corresponds to the other of the two adjacent bases, and the second fixing structure is connected to the second connecting structure.

[0006] In the above scheme, adjacent adapters of the backplane assembly can be installed on different partitions of the hard disk rack, and the backplane can be connected to the adjacent adapters, so that the backplane can be installed on the partition through two adjacent adapters, and the backplane can correspond to the compartment formed by the two partitions on which the adjacent adapters are installed, that is, when the backplane is fixed to the partition through the adapter, the size of the backplane is smaller, and each backplane will not occupy too much installation space. The saved installation space can be used to install another backplane or other components, so that the installation space can be fully utilized and it helps to achieve modular design.

[0007] In one possible implementation, at least one first protrusion is provided on the first side of the backplate, the first fixing structure is provided at the first protrusion, a first mounting slot is provided on the base corresponding to the first side of the backplate, the first connecting structure is provided on the bottom wall of the first mounting slot, the first protrusion is provided within the first mounting slot, and the first fixing structure corresponds to the first connecting structure. In this way, the first side of the backplate overlaps the portion of the base provided with the first connecting structure, i.e., the first side of the backplate and the base partially overlap, which can reduce the backplate installation space occupied by the adapter / base, facilitating a miniaturized design or increasing the size of the backplate. Furthermore, the first protrusion is provided within the first mounting slot, which can reduce the thickness at the overlapping position.

[0008] In one possible implementation, the second side of the backplate is provided with at least one recessed portion, with second protrusions provided on both sides of the recessed portion, the second fixing structure is provided at the second protrusions, the base corresponding to the second side of the backplate is provided with a second mounting groove, the second connecting structure is provided on the bottom wall of the second mounting groove, the second protrusion is provided within the second mounting groove, and the second fixing structure corresponds to the second connecting structure. In this way, the second side of the backplate overlaps the portion of the base provided with the second connecting structure, i.e., the second side of the backplate and the base partially overlap, which can reduce the backplate installation space occupied by the adapter / base, facilitating a miniaturized design or increasing the size of the backplate. Furthermore, the second protrusion is provided within the second mounting groove, which can reduce the thickness at the overlapping position.

[0009] In one possible implementation, the base is further provided with a through-opening, which is used to cooperate and fix with the partition; wherein: the through-opening and at least one of the first connecting structure and the second connecting structure are spaced apart in the height direction; and / or the through-opening and at least one of the first connecting structure and the second connecting structure are spaced apart in the width direction. In this way, through the cooperation between the through-opening and the hook limiter on the partition, the adapter can be installed on the partition, and the movement of the backplane assembly in the width direction and the length direction can be limited. When the backplane assembly is installed in the chassis, the upper cover of the chassis can limit the movement of the backplane assembly in the height direction. Alternatively, a separate snap-fit ​​structure can be provided on the adapter to limit the movement of the backplane assembly in the height direction.

[0010] In one possible implementation, the through-opening includes a mounting portion and a fixing portion, the mounting portion being closer to the lower end of the base relative to the fixing portion, and the fixing portion being narrower than the mounting portion. This allows the hook on the partition to first be inserted into the mounting portion during installation, and then the back panel assembly is moved downward so that the hook is positioned within the fixing portion. Because the fixing portion is narrower than the mounting portion, movement of the back panel assembly in both the width and length directions can be better restricted.

[0011] In one possible implementation, the adapter further includes a first snap-fit ​​structure, which is disposed at at least one through-opening and includes: a first handle connected to the base and extending in a direction away from the base; an elastic portion connected to the first handle; and a wrench portion connected at an angle to the elastic portion and spaced apart from and opposite to the first handle; wherein: when the wrench portion is not subjected to force, the elastic portion is located within the mounting portion to limit movement of the back panel in the height direction; when the wrench portion is pulled toward the first handle, the portion of the elastic portion located within the mounting portion can be driven to move away from the mounting portion, allowing the back panel to move in the height direction. In this way, by providing the elastically deformable first snap-fit ​​structure and cooperating with a structure on the partition, such as a hook, the movement of the back panel in the height direction can be limited.

[0012] In one possible implementation, the adapter further includes a second latch structure and a second handle. The second latch structure is rotatably disposed at at least one through-opening of the base and is rotatable between a first position and a second position. The second handle is disposed on one side of the base along the height direction. In the first position, a portion of the second latch structure is located outside the mounting portion, enabling movement of the back panel in the height direction. In the second position, a portion of the second latch structure is located inside the mounting portion and engages with the second handle to prevent rotation of the second latch structure, thereby limiting movement of the back panel in the height direction. Thus, by providing the rotatable second latch structure and engaging with a structure on the partition, such as a hook, movement of the back panel in the height direction can be limited. Furthermore, the provision of the second handle facilitates access to and placement of the back panel assembly. Furthermore, when rotating the second latch structure, the user can press and pull the second handle toward the handle to rotate the second latch structure, thereby improving operational convenience. Furthermore, in the second position, the second handle also serves to limit the position of the second latch structure.

[0013] In one possible implementation, the base is provided with two through-openings spaced apart along the height direction, with the first connecting structure disposed between the two through-openings; wherein: the second connecting structure is disposed on one side of each through-opening along the width direction, and two second fixing structures are disposed on the second side of the back panel, with the two second fixing structures corresponding to the two second connecting structures respectively; or, the base is provided with a hook on one side along the height direction, and the second connecting structure is disposed on the other side of the base along the height direction opposite to the hook; the second side of the back panel is provided with a slot along one side along the height direction, and the second fixing structure is disposed on the other side of the back panel along the height direction, the hook engages with the slot, and the second connecting structure on the other side of the base corresponds to the second fixing structure on the second side of the back panel. In this way, the two through-openings on the base of the adapter can respectively mate with the two hooks on the partition, enabling the adapter to be securely mounted on the partition, and, through the two second connecting structures on the base or through the hook and second connecting structure on the base, adjacent back panels can be spliced ​​and connected and overlapped with the base.

[0014] In one possible implementation, the backplane assembly includes at least two backplanes, and two adjacent backplanes are spliced ​​and connected via the same base; the first connecting structure and the second connecting structure are provided on the same base between the two adjacent backplanes, and the first fixing structure of one of the two adjacent backplanes is connected to the first connecting structure on the same base, and the second fixing structure of the other of the two adjacent backplanes is connected to the second connecting structure on the same base. In this way, adjacent backplanes can be spliced ​​and connected through adapters, and adjacent backplanes correspond to adjacent compartments on the hard drive rack respectively. Without changing the hard drive rack structure, the backplanes installed on the extended hard drive rack can be spliced, which helps to achieve a modular design. In addition, adjacent backplanes can share a common adapter limiter, which helps to reduce costs and improve installation and disassembly efficiency.

[0015] In one possible implementation, the first protrusion on the first side of the backplane corresponds to the recess on the second side of the backplane along the height direction. The first protrusion on the first side of one of the two adjacent backplanes is connected to the base located between the two adjacent backplanes, and the second protrusion on the second side of the other of the two adjacent backplanes is connected to the base located between the two adjacent backplanes. At least a portion of the first protrusion of one of the two adjacent backplanes is located within the recess of the other of the two adjacent backplanes, thereby achieving splicing of the two adjacent backplanes. In this way, adjacent backplanes can be staggered and spliced ​​at the adapter, which can improve space utilization and facilitate further increasing the size of the backplanes.

[0016] In one possible implementation, the first protrusion is arranged in the middle of the first side of the back plate, and the first connecting structure is located in the middle of the base along the height direction; the recessed portion is arranged in the middle of the second side of the back plate, and the second connecting structure is located on at least one side of the first connecting structure along the height direction.

[0017] In one possible implementation, one of the first fixing structure and the first connecting structure is a first fixing hole, and the other is a first threaded hole, the first fixing hole being arranged correspondingly to the first threaded hole, and the backplate assembly further includes a first fastener, the first fastener passing through the first fixing hole and being arranged in the first threaded hole; and / or one of the second fixing structure and the second connecting structure is a second fixing hole, and the other is a second threaded hole, the second fixing hole being arranged correspondingly to the second threaded hole, and the backplate assembly further includes a second fastener, the second fastener passing through the second fixing hole and being arranged in the second threaded hole. In this way, the backplate and the base can be overlapped and connected by the fasteners.

[0018] In one possible implementation, at least one first positioning hole is provided on one of the first side of the backplate and the base, and a first positioning pin is provided on the other side corresponding to the first positioning hole, with the first positioning pin being disposed within the corresponding first positioning hole; and / or at least one second positioning hole is provided on one of the second side of the backplate and the base, and a second positioning pin is provided on the other side corresponding to the second positioning hole, with the second positioning pin being disposed within the corresponding second positioning hole. In this way, the base and backplate can be positioned and installed by cooperating with the positioning holes and positioning pins, which helps improve assembly efficiency. For example, a first positioning hole can be provided on the back panel near the first fixing structure, and correspondingly, a first positioning pin can be provided on the base near the first connecting structure. The first positioning pin and the first positioning hole can be positioned and matched to align the first fixing structure on the back panel with the first connecting structure on the base for installing the first fastener. For another example, a second positioning hole can be provided on the back panel near the second fixing structure, and correspondingly, a second positioning pin can be provided on the base near the second connecting structure. The second positioning pin and the second positioning hole can be positioned and matched to align the second fixing structure on the back panel with the second connecting structure on the base for installing the second fastener. Wherein, both the first fastener and the second fastener can be screws.

[0019] In a second aspect, an embodiment of the present application provides a computing device, comprising: a hard disk rack, comprising a bottom plate and a top plate relatively spaced apart, and a plurality of partitions spaced apart along the width direction between the bottom plate and the top plate, each of the partitions being provided with a hook on one side along the length direction, and compartments being formed between adjacent partitions; a backplane assembly provided in the first aspect above being provided on one side along the length direction of the hard disk rack, the through openings of adjacent adapters of the backplane assembly being mounted on hooks of different partitions, and each backplane corresponding to at least one compartment; a plurality of hard disks being provided in the compartments and connected to at least one backplane of the backplane assembly.

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0037] In the description of this application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting this application.

[0038] In the description of this application, unless otherwise clearly specified and limited, the terms "install", "connect" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0039] In the description of this specification, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments.

[0040] A hard drive backplane typically consists of a backplane body, multiple hard drive connectors located on a first side of the backplane body, and a motherboard signal connector located on a second side of the backplane body. The hard drive connectors connect to the hard drive interface, enabling information exchange between the backplane and the hard drive. The motherboard signal connectors connect to the motherboard's backplane signal connectors, allowing information exchange between the backplane and the motherboard. Thus, the hard drive backplane connects the hard drive to the motherboard.

[0041] In a server, multiple hard drives are typically installed in a drive rack. To ensure reliable connection between the hard drives and the drive connectors on the drive backplane, the drive backplane can be fixedly connected to the drive rack. Furthermore, to accommodate more hard drives and increase storage space, the drive space can be standardized. Specifically, the drive rack can be divided into multiple compartments, each of which can accommodate an equal number of hard drives, for example, eight hard drives. Each backplane can be connected to eight hard drives, creating an eight-drive backplane.

[0042] In order to fix the backplane to the hard drive rack, a through opening is set on the 8-disk backplane, which engages with the hooks on the hard drive rack. This makes the size of the 8-disk backplane much larger than the size of the 8 hard drives, resulting in the backplane and the compartment being unable to be set correspondingly, and the installation space cannot be fully utilized. It is also not conducive to achieving modular design.

[0043] In view of this, embodiments of the present application provide a backplane assembly and a computing device including the same. Adjacent adapters of the backplane assembly can be mounted on different partitions of a hard drive rack. The backplane is connected to the adjacent adapters and corresponds to the compartment formed by the two partitions on which the adjacent adapters are mounted. This means that when the backplane is secured to the partitions via the adapters, the backplane is smaller in size and does not occupy excessive installation space. The saved installation space can be used to install additional backplanes or other components, thereby fully utilizing the installation space and facilitating a modular design.

[0044] Figure 1A A schematic diagram of the assembly structure of a backplane assembly provided in the first embodiment of the present application. Figure 1B for Figure 1A The exploded structure diagram of the backplane assembly is shown in FIG. Figure 1A and Figure 1BAs shown, the backplane assembly includes at least two adapters 3 spaced apart and at least one backplane 2. Each adapter 3 includes a base 31, two adjacent bases 31 are used to be installed on different partitions of the hard disk rack, and at least one of the two adjacent bases 31 is provided with a first connecting structure L1, and at least the other of the two adjacent bases 31 is provided with a second connecting structure L2. A first fixing structure D1 is provided on the first side of the backplane 2, and a second fixing structure D2 is provided on the second side of the backplane 2 opposite to the first side. Exemplarily, a plurality of partitions may be spaced apart along the width direction X, in which case the first side of the backplane 2 and the second side of the backplane 2 are oppositely arranged along the width direction X, and at least one backplane 2 and at least two spaced adapters 3 may be provided on one side of the plurality of partitions of the hard disk rack along the length direction Y.

[0045] Among them, the first side of the back plate 2 corresponds to one of the two adjacent bases 31, and the first fixing structure D1 is connected to the first connecting structure L1, and the second side of the back plate 2 corresponds to the other of the two adjacent bases 31, and the second fixing structure D2 is connected to the second connecting structure L2.

[0046] In other words, the adapters connected on both sides of the backplane can be installed on different partitions of the hard drive rack, so that the first side of backplane 2 corresponds to one of the multiple partitions of the hard drive rack, and the second side of backplane 2 corresponds to another of the multiple partitions of the hard drive rack. Compartments for installing hard drives are formed between adjacent partitions, and backplane 2 can be set to correspond to at least one compartment. In this way, when the backplane is fixed to the partition via the adapter, the backplane size is smaller and does not occupy too much installation space. The saved installation space can be used to install another backplane or other components, thereby fully utilizing the installation space and facilitating the realization of a modular design.

[0047] Furthermore, the first side of the back panel 2, provided with the first fixing structure D1, can overlap the portion of one of the two adjacent bases 31 provided with the first connecting structure L1. The second side of the back panel 2, provided with the second fixing structure D2, can overlap the portion of the other of the two adjacent bases 31 provided with the second connecting structure L2. This allows the back panel 2 and base 31 to overlap in the width direction X, preventing the adapter from occupying too much space in the back panel installation. This facilitates the miniaturization of the back panel assembly in the width direction X, or increases the size of the back panel in the width direction X.

[0048] For example, Figure 1A and Figure 1BAs shown, the first side of the back panel 2 may be provided with at least one first protrusion T1, the first fixing structure D1 is provided at the first protrusion T1, the base 31 corresponding to the first side of the back panel 2 is provided with a first mounting groove C1, the first connecting structure L1 is provided on the bottom wall of the first mounting groove C1, the first protrusion T1 is provided in the first mounting groove C1, and the first fixing structure D1 corresponds to the first connecting structure L1. Disposing the first protrusion T1 in the first mounting groove C1 in this way not only enables the first side of the back panel 2 to overlap with the base 31, but also reduces the thickness at the overlapping position. At the same time, the first mounting groove C1 can also play a certain limiting role. In addition, the first side of the back panel 2 can be flush with the surface of the base 31 facing the hard disk rack, which makes the assembly more compact and avoids excessive gaps.

[0049] The second side of the back panel 2 may be provided with at least one recessed portion, with second protrusions T2 provided on both sides of the recessed portion. A second fixing structure D2 is provided at the second protrusion T2. ​​The base 31 corresponding to the second side of the back panel 2 is provided with a second mounting groove C2. The second connecting structure L2 is provided on the bottom wall of the second mounting groove C2. The second protrusion T2 is provided within the second mounting groove C2. The second fixing structure D2 corresponds to the second connecting structure L2. Placing the second protrusion T2 within the second mounting groove C2 not only enables the second side of the back panel 2 to overlap with the base 31, but also reduces the thickness at the overlapping position. At the same time, the second mounting groove C2 can also play a certain limiting role. In addition, the second side of the back panel 2 can be flush with the surface of the base 31 facing the hard disk rack, which makes the assembly more compact and avoids excessive gaps.

[0050] In some examples, the first protrusion T1 may be located in the middle of a first side of the back plate 2 along the width direction X, and the first connection structure L1 may be located in the middle of the base 31 along the height direction Z. The recessed portion may be located in the middle of a second side of the back plate 2 along the width direction X, and the second connection structure L2 may be located on at least one side of the first connection structure L1 along the height direction Z. In other examples, the first protrusion T1 may not be located in the middle of the first side of the back plate 2, and accordingly, the recessed portion may not be located in the middle of the second side of the back plate 2.

[0051] And, as Figure 1A and Figure 1BAs shown, when the first protrusion T1 has a larger dimension along the width direction X, the first fixing structure D1 can be disposed on the first protrusion T1. When the second protrusion T2 has a smaller dimension along the width direction X, the second fixing structure D2 can be disposed near the second protrusion T2. ​​In other examples, if the first protrusion T1 has a smaller dimension along the width direction X, the first fixing structure D1 can be disposed near the first protrusion T1. If the second protrusion T2 has a larger dimension along the width direction X, the second fixing structure D2 can be disposed on the second protrusion T2. ​​That is, "the first fixing structure D1 is disposed at the first protrusion T1" can mean that the first fixing structure D1 is disposed on the first protrusion T1 or that the first fixing structure D1 is disposed near the first protrusion T1; and "the second fixing structure D2 is disposed at the second protrusion T2" can mean that the second fixing structure D2 is disposed on the second protrusion T2 or that the second fixing structure D2 is disposed near the second protrusion T2.

[0052] In order to ensure that the base 31 is reliably connected to the partition of the hard disk rack, a through opening K is further provided on the base 31, and the through opening K is used to cooperate with the partition for fixation. For example, the through opening K is used to be detachably mounted on a hook provided on the side of the partition facing the back panel assembly to cooperate with the hook limit. In this way, by cooperating with the through opening K and the hook limit, the adapter can be installed on the partition, and the movement of the back panel assembly along the width direction X and the length direction Y can be limited. When the back panel assembly is installed in the chassis, the upper cover of the chassis can limit the movement of the back panel assembly along the height direction Z, or a snap-on structure to be described below can be provided on the adapter 3 to limit the movement of the back panel assembly along the height direction Z.

[0053] The through-opening K may include a mounting portion K1 and a fixing portion K2. The mounting portion K1 is located closer to the lower end of the base 31 relative to the fixing portion K2, and the width of the fixing portion K2 is smaller than that of the mounting portion K1. During installation, the hook on the partition can be first inserted into the mounting portion K1, and then the backplane assembly can be moved downward so that the hook is located in the fixing portion K2. Since the width of the fixing portion K2 is smaller than that of the mounting portion K1, the movement of the backplane assembly along the width direction X and the length direction Y can be better restricted. Furthermore, the wider mounting portion K1 makes it easier for the hook to be inserted into the through-opening K, which facilitates the installation of the backplane assembly on the hard drive rack.

[0054] In addition, Figure 1A and Figure 1BIn the embodiment, the through-opening K and the second connecting structure L2 are spaced apart along the width direction X. In this case, the second protrusion T2 has a smaller dimension along the width direction X, and the second fixing structure D2 can be positioned closer to the second protrusion T2. ​​The first protrusion T1 has a larger dimension along the width direction X, and the first fixing structure D1 can be positioned on the first protrusion T1. In other examples, the through-opening K can be spaced apart from the first connecting structure L1 along the width direction X. In this case, the dimension of the first protrusion T1 along the width direction X can be designed to be smaller, the first fixing structure D1 can be positioned closer to the first protrusion T1, the dimension of the second protrusion T2 along the width direction X can be designed to be larger, and the second fixing structure D2 can be positioned on the second protrusion T2.

[0055] That is, the through opening K may be spaced apart from at least one of the first connection structure L1 and the second connection structure L2 along the width direction X. In other examples, the through opening K may also be spaced apart from at least one of the first connection structure L1 and the second connection structure L2 along the height direction Z.

[0056] To more reliably and stably mount the back panel assembly to the shelf, the base 31 is provided with two through-openings K spaced apart along the height direction Z. For example, the two through-openings K can be removably mounted on two hooks G spaced apart along the height direction Z of the corresponding shelf. A first connecting structure L1 is disposed between the two through-openings K. A hook J is disposed on one side of the base 31 along the height direction Z, and a second connecting structure L2 is disposed on the other side, opposite the hook J. A slot C is disposed on one side of the second side of the back panel 2 along the height direction Z, and a second fixing structure D2 is disposed on the other side of the second side of the back panel 2 along the height direction Z. For example, the second fixing structure D2 is disposed on one of the two second protrusions T2 on either side of the recessed portion of the back panel 2, and a slot C is disposed on the other side of the back panel 2, away from the recessed portion. The hook J engages with the slot C, and the second connecting structure L2 on the other side of the base 31 corresponds to the second fixing structure D2 on the second side of the back panel 2.

[0057] Among them, the first mounting groove C1 can be located in the middle of the base 31 along the height direction Z, the two through openings K can be located on both sides of the first mounting groove C1 respectively, the second mounting groove C2 can be located on one side of the through opening K along the width direction X, and the first mounting groove C1 and the second mounting groove C2 are open on one side away from each other.

[0058] In this case, the second protrusion T2 has a smaller dimension along the width direction X, and the slot C can be provided near the second protrusion T2. ​​In other examples, if the second protrusion T2 has a larger dimension along the width direction X, the slot C can be located on the second protrusion T2. ​​In other words, "the other second protrusion T2 is provided with the slot C on a side away from the recessed portion" can mean that the slot C is provided on the second protrusion T2 or that the slot C is provided near the second protrusion T2.

[0059] That is, the first connecting structure L1 and the second connecting structure L2 of the base 31 can be spaced apart along the height direction Z, and the mating structure between the base 31 and the partition of the hard disk rack, namely the through-opening K, can be spaced apart from the second connecting structure along the width direction X, thereby enabling the base 31 to be reliably connected to the partition while being overlapped with the back panel 2. In other examples, a second connecting structure L2 can be provided on one side of each through-opening K along the width direction X, and two second fixing structures D2 can be provided on the second side of the back panel 2. For example, second fixing structures D2 can be provided on the second protrusions T2 on both sides of the recessed portion of the second side of the back panel 2 along the height direction Z, respectively. The two second fixing structures D2 correspond to the two second connecting structures L2, respectively.

[0060] For example, one of the first fixing structure D1 and the first connecting structure L1 may be a first fixing hole, and the other may be a first threaded hole, and the first fixing hole and the first threaded hole are arranged correspondingly. Figure 1A and Figure 1B In the figure, the first fixing structure D1 is a first fixing hole, and the first connecting structure L1 is a first threaded hole. The back panel assembly may further include a first fastener (not shown in the figure), which passes through the first fixing hole and is arranged in the first threaded hole. For example, one of the second fixing structure D2 and the second connecting structure L2 may be a second fixing hole, and the other may be a second threaded hole, and the second fixing hole and the second threaded hole are arranged correspondingly. Figure 1A and Figure 1B In the figure, the second fixing structure D2 is a second fixing hole, and the second connecting structure L2 is a second threaded hole. The back plate assembly may further include a second fastener (not shown in the figure), which passes through the second fixing hole and is disposed in the second threaded hole.

[0061] That is, the first side of the back panel 2 can overlap the portion of the base 31 of one of the two adjacent adapters 3 where the first connection structure L1 is located, so that the first fixing structure D1 is disposed correspondingly to the first connection structure L1 of one of the two adjacent adapters 3 and connected via the first fastener. The second side of the back panel 2 can overlap the portion of the base 31 of the other of the two adjacent adapters 3 where the second connection structure L2 is located, so that the second fixing structure D2 is disposed correspondingly to the second connection structure L2 and connected via the second fastener. In this way, the back panel 2 and the base 31 can be overlapped and connected via the fasteners.

[0062] like Figure 1BAs shown, in order to enable the base 31 and the back panel 2 to be positioned and installed so as to improve assembly efficiency. At least one first positioning hole H1 may be provided on the first side of the back panel 2 and one of the base 31, and a first positioning pin A1 may be provided on the other side corresponding to the first positioning hole H1. The first positioning pin A1 is set in the corresponding first positioning hole H1, that is, the first positioning pin A1 and the first positioning hole H1 can be positioned and matched. At least one second positioning hole H2 may be provided on the second side of the back panel 2 and one of the base 31, and a second positioning pin A2 may be provided on the other side corresponding to the second positioning hole H2. The second positioning pin A2 is set in the corresponding second positioning hole H2, that is, the second positioning pin A2 and the second positioning hole H2 can be positioned and matched.

[0063] In some examples, such as Figure 1B As shown, two positioning holes H1 are provided on the first protrusion T1 on the first side of the back plate 2, and the two positioning holes H1 are located on both sides of the first fixing structure D1 along the height direction Z. Thus, the two positioning holes H1 are respectively positioned and matched with the two first positioning pins A1 on the base 31, so that the first fixing structure D1 and the first connecting structure L1 can be aligned to facilitate the installation of the first fastener.

[0064] For example, a second positioning hole H2 is provided at the second protrusion T2 on one side of the recessed portion of the second side of the back panel 2 along the height direction Z. The second positioning hole H2 is elliptical and is located near the second fixing structure D2. A slot C is provided at the second protrusion T2 on the other side of the recessed portion of the second side of the back panel 2 along the height direction Z. Thus, when assembling the base 31 and the back panel 2, the second positioning pin A2 on the base 31 can be first inserted into the elliptical second positioning hole H2, and then the hook J on the base 31 can be engaged with the slot C of the back panel 2. This aligns the second fixing structure D2 with the second connecting structure L2, facilitating installation of the second fastener. In other words, the elliptical shape of the second positioning hole H2 facilitates the secure engagement of the hook J with the slot C.

[0065] In this way, accurate positioning can also be achieved through the slot C and the elliptical second positioning hole H2. In other examples, two second positioning holes H2 can also be provided on the second side of the back plate 2 to achieve positioning. In addition, when positioning is performed through the slot C and the elliptical second positioning hole H2, two second connecting structures L2 can be provided on the base 31. The second connecting structures L2 can be threaded holes, one of the second connecting structures L2 can be aligned with the second fixing structure D2 and installed with a second fastener, and the other second connecting structure L2 can be aligned with the fixing hole on the mounting portion 320 of the first snap structure 32 to be described below to install a third fastener Q, thereby achieving a fixed connection between the first snap structure 32 and the base 31. Among them, the first fastener, the second fastener, and the third fastener can all be screws.

[0066] Figure 2This is a schematic diagram of the assembly structure of a backplane assembly provided in the second embodiment of the present application. The difference from the backplane assembly shown in Figure 1 is that Figure 2 In the embodiment, a backplane 2 and an adapter 3 are added, that is, the backplane assembly includes at least two backplanes 2, and the two adjacent backplanes 2 are spliced ​​and connected through the same base 31. A first connecting structure L1 and a second connecting structure L2 are provided on the same base 31 between the two adjacent backplanes 2. The first fixing structure D1 of one of the two adjacent backplanes 2 is connected to the first connecting structure L1 on the same base 31, and the second fixing structure D2 of the other of the two adjacent backplanes 2 is connected to the second connecting structure L2 on the same base 31. In this way, the adjacent backplanes can be spliced ​​and connected through the adapter, and the adjacent backplanes correspond to the adjacent compartments on the hard disk rack respectively. Without changing the structure of the hard disk rack, the backplanes installed on the extended hard disk rack can be spliced, which helps to achieve a modular design. In addition, the adjacent backplanes 2 can share an adapter 3 for limiting, which is beneficial to reducing costs and improving installation and disassembly efficiency.

[0067] The first protrusion T1 on the first side of the back panel 2 and the recessed portion on the second side of the back panel 2 may correspond to each other along the height direction Z. The first protrusion T1 on the first side of one of the two adjacent back panels 2 is connected to the base 31 located between the two adjacent back panels 2, and the second protrusion T2 on the second side of the other of the two adjacent back panels 2 is connected to the base 31 located between the two adjacent back panels 2. At least a portion of the first protrusion T1 of one of the two adjacent back panels 2 is located within the recessed portion of the other of the two adjacent back panels 2, thereby achieving splicing of the two adjacent back panels 2. In this way, adjacent back panels can be staggered and spliced ​​at the adapter and can overlap the adapter. For example, the first connecting structure L1 on the adapter 3 can be connected to the first fixing structure D1 of one of the two adjacent back panels 2 via a first fastener, and the second connecting structure L2 on the adapter 3 can be connected to the second fixing structure D2 of the other of the two adjacent back panels 2 via a second fastener. This can improve space utilization and facilitate further increasing the size of the back panel.

[0068] Figure 3 for Figure 1A and Figure 2 The three-dimensional structure diagram of the adapter of the backplane assembly is shown in FIG. Figure 3As shown, in order to limit the movement of the back panel 2 along the height direction Z, the adapter 3 may further include a first snap-fit ​​structure 32, and the first snap-fit ​​structure 32 is provided at at least one through opening K. The first snap-fit ​​structure 32 includes a first handle 321, an elastic portion 322, and a wrench portion 323. The first handle 321 is connected to the base 31 and extends in a direction away from the base 31. The elastic portion 322 is connected to the first handle 321. The wrench portion 323 is connected to the elastic portion 322 at an angle and is opposite to and spaced from the first handle 321. When the wrench portion 323 is not subjected to force, the elastic portion 322 is located in the mounting portion K1. For example, the elastic portion 322 can cooperate with the hook limiter of the partition extending into the through opening K to limit the movement of the back panel 2 along the height direction Z. When the wrench part 323 is pulled toward the first handle 321, the part of the elastic part 322 located in the installation part K1 can be driven to move away from the installation part K1. For example, in this way, the elastic part 322 can be disengaged from the limit fit with the hook extending into the through opening K of the partition, so that the back panel 2 can move along the height direction Z.

[0069] Among them, the material of the base 31 can be the same as the material of the first snap-fit ​​structure 32, and in order to reduce costs, the material of the adapter 3 can be plastic. If necessary, the material of the base 31 can be different from the material of the first snap-fit ​​structure 32. For example, the first snap-fit ​​structure 32 can also include a mounting portion 320. The mounting portion 320 can be fixedly connected to the base 31 by, for example, the third fastener Q mentioned above. The first handle 321 is connected to the mounting portion 320 and extends along a plane away from the back plate 2. In addition, under the premise of ensuring that the free end of the elastic portion 322 can be elastically deformed, the elastic portion 322 can also be connected to at least part of the mounting portion 320, so that the connection of the elastic portion 322 is more reliable. In addition, an avoidance space is provided at the position corresponding to the elastic portion 322 and the fixed portion K2 that passes through the opening K (see the description below). Figure 10 ), in addition, the specific working principle of the first buckle structure 32 will be described in the following Figure 10 Department introduction.

[0070] Figure 4 This is a schematic diagram of the assembly structure of a backplane assembly provided in the third embodiment of the present application. Figure 4 As shown, the backplane assembly includes three backplanes 2 and four adapters 3. Among them, the adapters 3 located between adjacent backplanes 2 and the adapters 3 located on one side of the backplane assembly along the backplane arrangement direction are connected to the adapters 3 located between adjacent backplanes 2 and the adapters 3 located on the one side of the backplane assembly along the backplane arrangement direction. Figure 3 The other structures of the adapter 3 except the first buckle structure 32 and the first handle 321 can be the same, the difference is that the second buckle structure 33 and the second handle 34 are used. Figure 5A and Figure 5BIn addition, the structure of the adapter 3 located on the other side of the backplane assembly along the backplane arrangement direction can be simplified and / or changed. Figure 6A and Figure 6B Give a detailed introduction.

[0071] Figure 5A for Figure 4 The schematic diagram of the three-dimensional structure of the adapter of the backplane assembly shown is in a limited state. Figure 5B for Figure 5A The schematic diagram of the three-dimensional structure of the adapter is not in the limited state. Figure 5A and Figure 5B As shown, the adapter 3 may further include a second snap-fit ​​structure 33 and a second handle 34. The second snap-fit ​​structure 33 is rotatably disposed at at least one through-opening K of the base 31 and is rotatable between a first position and a second position. The second handle 34 is disposed on one side of the base 31 along the height direction Z.

[0072] Among them, such as Figure 5B As shown, in the first position, part of the second snap structure 33 (such as the second limiting structure 333 to be described below) is located outside the mounting portion K1. For example, in this way, part of the second snap structure 33 can cooperate with the hook of the partition extending into the through opening K to enable the back panel 2 to move along the height direction Z; Figure 5A As shown, in the second position, a portion of the second snap-fit ​​structure 33 (such as the second limiting structure 333 described below) is located within the mounting portion K1 and engages with the second handle 34 to prevent the second snap-fit ​​structure 33 from rotating. For example, a portion of the second snap-fit ​​structure 33 can engage with a hook on the partition extending through the opening K, thereby limiting movement of the back panel 2 along the height direction Z. Furthermore, the second handle 34 and the base 31 can be integrally formed or formed separately. The provision of the second handle 34 facilitates the removal and placement of the back panel. When rotating the second snap-fit ​​structure 33, the user can press the second handle 34 and pull the second snap-fit ​​structure 33 toward the second handle 34 to rotate it, thereby improving operational convenience. Furthermore, in the second position, the second handle 34 also serves to limit the position of the second snap-fit ​​structure 33.

[0073] like Figure 5A and Figure 5BAs shown, in some examples, the second locking structure 33 may include a main body 331, a first limiting structure 332, and a second limiting structure 333. A hole is provided on the base 31. A shaft is provided at one end of the main body 331 along the height direction Z. The shaft is rotatably mounted within the hole. The first limiting structure 332 is connected to the other end of the main body 331 along the height direction Z at an angle and extends in a direction away from the plane of the base 31. At least one of the first limiting structure 332 and the second handle 34 is elastic. Therefore, when the second limiting structure rotates from the first position to the second position along with the main body 331, at least one of the first limiting structure 332 and the second handle 34 can deform, thereby causing the first limiting structure 332 and the second handle 34 to cooperate with each other in a limiting manner to restrict the position of the second locking structure 33.

[0074] Illustratively, the first retaining structure 332 may include a retaining body X1 and a retaining boss X2. The retaining body X1 is connected to the main body 331, and the retaining boss X2 is disposed on the side of the retaining body X1 facing the second handle 34. In the second position, the retaining boss X2 engages with the retaining groove X2 of the second handle 34, that is, the retaining boss X2 can be retained within the retaining groove. As a result, when the second snap structure 33 is rotated from the first position to the second position, at least one of the retaining boss X2 and the second handle 34 deforms with minimal resistance, facilitating operation. This allows the retaining boss to slide into the retaining groove. Optionally, the retaining body X1 may also deform at this time.

[0075] Of course, in other embodiments, the limiting boss may be provided on the handle, and the limiting groove may be provided on the limiting body.

[0076] Additionally, the second handle 34 can be hollow, allowing for easier deformation when squeezed by the limiting boss X2, while also reducing weight. Furthermore, a notch E can be provided at the corner where the first limiting structure 332 meets the main body 331, facilitating deformation and reducing weight. Furthermore, to enhance structural strength, support plates R can be provided on either side of the notch E at the corner between the first limiting structure 332 and the main body 331. For example, the support plates R can be triangular in shape.

[0077] The second retaining structure 333 is disposed on a side of the main body 331 near the through-opening K along the width direction X. In the second position, the hook on the partition can hook onto the plate B at the top of the through-opening K. For example, the surface of the plate B facing the second latching structure 33 is lower and can be located within the through-opening K, thereby forming a latching slot within which the hook on the partition can be located. In the second position, the second retaining structure 333 can extend into the through-opening K and abut against the bottom of the hook, securely engaging the hook G with the through-opening K, thereby preventing the back panel 2 and adapter 3 from moving upward and limiting movement of the back panel 2 in the height direction Z. To remove the back panel assembly from the partition, the second latching structure 33 can be rotated from the second position to the first position. At this point, the second retaining structure 333 is located outside the through-opening K and no longer abuts against the bottom of the hook, allowing the back panel 2 and adapter 3 to move upward.

[0078] That is to say, the adapter 3 may include a plastic base and a rotating buckle (i.e., a second buckle structure). The plastic base is provided with two fixing holes (e.g., the first connecting structure L1 and / or the second connecting structure L2) and corresponding positioning pins (e.g., the first positioning pin A1 and / or the second positioning pin A2) for fixing to the back panel; the plastic base is also provided with a through opening K, which can be used to respectively cooperate with the hook limit of the hard disk rack to achieve positioning in the front-to-back direction (i.e., the length direction Y) and the left-to-right direction (i.e., the width direction X); the plastic base also has a handle (i.e., the second handle 34), which the user can hold to take and place the back panel assembly. At the same time, the handle can serve as the female end of the rotating buckle, and the handle can be pressed to pull the rotating buckle to rotate the rotating buckle. The rotating clip may include a rotating shaft and a rotating limiting structure (such as a first limiting structure 332), so that the rotating clip and the base can cooperate to achieve rotational positioning; the rotating clip may also include a vertical limiting structure (such as a second limiting structure 333), and the vertical limiting structure can cooperate with the hook of the hard disk rack to limit the up and down direction of the backplane (i.e., the height direction Z).

[0079] Figure 6A for Figure 4 A schematic structural diagram of another adapter of the backplane assembly shown in the main viewing direction. Figure 6B for Figure 6A The schematic diagram of the structure of another adapter in the rear view direction is shown in FIG. Figure 6A and Figure 6B As shown, due to the Figure 4The adapter 3 on the other side of the backplane assembly shown only needs to be connected to one backplane 2. Therefore, the structure of the adapter 3 can be simplified. For example, the base 31 can only be provided with structures that mate with the first side of the backplane 2, such as the first mounting groove C1, the first connecting structure L1, and the two first locating pins A1. In other examples, the base 31 of the adapter 3 on the other side of the backplane assembly can only be provided with structures that mate with the second side of the backplane 2, such as the second mounting groove C2, the second connecting structure L2, the second locating pin A2, etc.

[0080] Furthermore, since the structure of one side of the hard disk rack may be different from that of the other side, for example, 9 hard disks are installed in the compartments on one side of the hard disk rack and 8 hard disks are installed in the other compartments, the structure of the adapter 3 on one side or the other side of the backplane assembly can be appropriately changed to adapt to the hard disk rack. For example, Figure 6A and Figure 6B In the embodiment, the through opening K on the base 31 is not a closed structure. For example, since the second snap-fit ​​structure 33 on the other adapter 3 of the backplane assembly can well limit the movement of the backplane assembly along the height direction Z, the adapter 3 located on one side or the other side of the backplane assembly may no longer be provided with a snap-fit ​​structure, such as the first snap-fit ​​structure 32 or the second snap-fit ​​structure 33. Figure 6A As shown, a step F can also be provided on the base 31 to facilitate positioning and installation.

[0081] In addition, Figure 1A and Figure 1B In the figure, the backplane assembly includes a backplane 2 and two adapters 3. Figure 2 In the figure, the backplane assembly includes two backplanes 2 and three adapters 3. Figure 4 In the embodiment, the backplane assembly includes three backplanes 2 and four adapters 3. In other examples, the backplane assembly may include more backplanes 2 and more adapters 3.

[0082] Figure 7 This is a partial structural diagram of a computing device provided in the first embodiment of the present application. Figure 7 As shown, the computing device includes a hard disk rack 10, a plurality of hard disks (not shown) and the aforementioned backplane assembly 20. The backplane assembly 20 includes a backplane 2 and two adapters 3.

[0083] Figure 8 This is a partial structural diagram of a computing device provided in the second embodiment of the present application. Figure 8 As shown, the computing device includes a hard disk rack 10, a plurality of hard disks (not shown) and the aforementioned backplane assembly 20. The backplane assembly 20 includes two backplanes 2 and three adapters 3.

[0084] Figure 9AA schematic diagram of the partial structure of a computing device provided in the third embodiment of the present application. Figure 9B for Figure 9A An exemplary decomposition structure diagram of a computing device is shown. Figure 9A and Figure 9B As shown, the computing device includes a hard disk rack 10, a plurality of hard disks (not shown) and the aforementioned backplane assembly 20. The backplane assembly 20 includes three backplanes 2 and four adapters 3.

[0085] And, in Figure 7 、 Figure 8 、 9A and Figure 9B In the computing device shown, for example, the adapter 3 is Figure 3 Alternatively, the computing device may also be installed with the adapter shown. Figure 5A and Figure 5B The adapter shown can also be installed Figure 6A and Figure 6B The adapter shown. Furthermore, the hard disk rack 10 of these computing devices may include a bottom plate 101 and a top plate 102 that are relatively spaced apart, and a plurality of partitions 103 that are spaced apart along the width direction X between the bottom plate 101 and the top plate 102, each partition 103 is provided with a hook G on one side along the length direction Y, and illustratively, each partition 103 is provided with two hooks G along the height direction Z, and compartments are formed between adjacent partitions 103. The backplane assembly 20 is provided on one side of the hard disk rack 10 along the length direction Y, and the through openings K of adjacent adapters 3 of the backplane assembly 20 are installed on the hooks G of different partitions 103, and each backplane 2 corresponds to at least one compartment. Multiple hard disks are provided in the compartments and are connected to at least one backplane 2 of the backplane assembly. In addition, the computing device may be a server. The computing device may also include a chassis (not shown in the figure), and the hard disk rack 10 is provided in the chassis.

[0086] That is, the backplane of the backplane assembly is installed on the partition through the adapter, and the backplane can correspond to the compartment formed by the two partitions, which makes it easy to fully utilize the backplane installation space and helps to achieve modular design. In addition, the adapter allows adjacent backplanes to be spliced ​​and connected, and the adapters between adjacent backplanes will not occupy too much space for installing the backplane, so that adjacent backplanes correspond to adjacent hard disk compartments on the hard disk rack respectively. Without changing the hard disk rack structure, the backplanes installed on the extended hard disk rack can be spliced. Figure 7 As shown, a back plate 2 can be installed corresponding to each compartment, and the adapters 3 connected on both sides of the back plate are respectively installed on the two partitions forming the compartment; Figure 8 As shown, two back plates 2 are installed in correspondence with the two compartments. The back plates 2 correspond to the compartments one by one. The three partitions forming the two compartments are respectively installed with adapters 3, that is, there are three adapters in total. There is a back plate 2 connected between adjacent adapters 3. Figure 9A and Figure 9B As shown, three back panels 2 are installed corresponding to the three compartments. The back panels 2 correspond to the compartments one by one. Adapters 3 are installed on the four partitions forming the three compartments, that is, there are four adapters in total. A back panel 2 is connected between adjacent adapters 3.

[0087] Figure 10 for Figure 9A The computing device shown is a partial cross-sectional enlarged structural diagram along the MM line. Figure 10 As shown, when the wrench portion 323 is unloaded, the elastic portion 322 is located within the through-opening K, and the clearance space of the elastic portion 322 can engage with the hook G on the partition 103 to limit the movement of the backplate 2 in the height direction Z. When the wrench portion 323 is pulled toward the first handle 321, the free end of the elastic portion 322 not connected to the first handle 321 can be driven to rotate away from the through-opening K, opening one side of the clearance space and releasing the restraining engagement with the hook G. At this point, the backplate assembly 20 can be moved upward and removed from the hard drive cage.

[0088] To sum up, the existing hard disk backplane is relatively large in size. For example, after designing a fixed structure on the backplane, the size of the 8-disk backplane is larger than the sum of the sizes of the 8 hard disks, and it cannot be set corresponding to the standardized compartment for placing the hard disks. As a result, the hard disk backplane cannot be expanded and installed without changing the hard disk rack structure, which is not conducive to the modular design of the hard disk backplane. In addition, a limiting member is also provided in the middle part of the 8-disk backplane along the width direction. The limiting member can cooperate with the limiting boss on the bottom plate of the hard disk rack to limit the position of the 8-disk backplane, that is, each backplane is designed with a limiting structure separately, so that adjacent backplanes cannot share the same limiting structure for limiting, which is not conducive to reducing costs and improving installation and disassembly efficiency.

[0089] The solution of the embodiment of the present application designs a RAID (redundant array of independent disks, referred to as hard disk array) hard disk backplane, which can connect multiple hard disks. The backplane is fixed to the partition through an adapter. Each hard disk backplane is small in size and can be set corresponding to a standardized compartment. In addition, the adapter can enable adjacent hard disk backplanes to be modularly spliced. At the same time, adjacent backplanes can share an adapter limiter. The adapter can limit the hard disk backplane in the X direction, Y direction and Z direction, which is conducive to reducing costs and improving installation and disassembly efficiency.

[0090] Specifically, adapters can be connected to either side of the backplane's width. One backplane and two adapters can form an eight-drive backplane module. The adapters can be made of plastic and feature backplane stop and fix mechanisms that position the hard drive backplane in both length and width. They're also compatible with the chassis' hook-style stop features, including upper and lower stop snaps and a backplane handle.

[0091] For example, multiple hard disk backplanes can be connected through adapters to connect more hard disks at the same time. For example, if 8 hard disks can be installed in each hard disk rack compartment, Figure 1A 、 Figure 1B and Figure 7 As shown in the figure, a single hard disk backplane can connect 8 hard disks; Figure 2 and Figure 8 As shown, two hard disk backplanes can be connected to 16 hard disks; Figure 4 、 Figure 9A and Figure 9B As shown, three hard drive backplanes can be spliced ​​to connect 24 hard drives. This can simultaneously meet the needs of 8, 16, and 24 disks. The assembly process can be specifically as follows: For an 8-disk backplane, the first side of the backplane and an adapter can be fixed by two locating pins and a countersunk screw, and the second side of the backplane and another adapter can be fixed by a locating pin, a hook, and a countersunk screw. For a 16-disk backplane, add a backplane and an adapter to the 8-disk backplane assembly, and repeat the fixing scheme on both sides; for a 24-disk backplane, add a backplane and an adapter to the 16-disk backplane assembly, and repeat the fixing scheme on both sides. In this way, a modular 8-disk backplane solution is designed based on the current chassis, which meets the needs of backplane normalization and splicing expansion.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and do not limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
