Description

Technical Field

[0001] The utility model belongs to the technical field of computer accessories, in particular to a memory support structure and a server suitable for a double-layer motherboard. Background Art

[0002] A server is a specialized IT device that provides computing power and runs software applications within a network environment. It provides computing or application services to other clients (such as personal computers, smartphones, ATMs, and other terminal devices) within the network. Generally speaking, a server is capable of responding to service requests, providing services, and guaranteeing services. Compared to ordinary computers, servers possess high-speed CPU computing power, long-term reliable operation, strong I / O data throughput, and high scalability. As electronic devices, servers have a complex internal structure. Key components include a CPU, memory, chipset, I / O devices, storage, peripherals, voltage regulators, power supplies, and cooling systems.

[0003] With the rapid development of technology, server performance requirements are increasing, and server configurations and layouts are becoming increasingly compact. To meet these high-performance requirements, some 2U servers are equipped with two motherboards. This allows for the installation of more CPUs, memory, and other components, significantly improving server performance.

[0004] However, placing two motherboards in the same height space inevitably results in a tighter space, with a smaller gap between them. This is especially true for models with memory modules positioned in the middle of the motherboard. During full-machine impact testing, the upper motherboard will come into contact with the memory modules on the lower motherboard, causing stress on the memory modules, impacting their function and, in severe cases, causing them to fail. Preventing or minimizing the impact of the upper motherboard on the lower memory modules, even with a smaller gap, became a pressing design challenge.

[0005] In current dual-motherboard servers, due to the compact space, the clearance between the lower motherboard and the upper motherboard is very small, typically only 2mm. This results in significant deformation of the upper motherboard during a crash, impacting the lower motherboard's memory, causing stress on the memory and potentially causing serious failure. Utility Model Content

[0006] In order to solve the problem that in a server with a double-layer motherboard, deformation of the upper motherboard may easily cause impact or even damage to the memory on the lower motherboard during the whole-machine impact test, the utility model provides a memory support structure and server suitable for double-layer motherboards by adding a support member between the upper and lower motherboards.

[0007] The utility model is realized through the following technical solutions:

[0008] A memory support structure suitable for a double-layer motherboard includes a support block body installed between an upper motherboard and a lower motherboard. The support block body includes support plates respectively abutting the upper motherboard and the lower motherboard. Support seats are provided on both sides of the support plate close to the memory stick insertion position. The support seats extend toward the memory stick insertion position. The two support seats and the support plate form a first avoidance space of a U-shaped structure in the horizontal plane.

[0009] The support block body is supported on the bottom of the upper mainboard which is prone to deformation, to prevent the upper mainboard from deforming downward and causing damage to the components on the lower mainboard; the support plate is located on the memory stick side of the lower mainboard, and the two support seats on the support plate extend toward the memory stick side, which can protect the memory stick and ensure the operating space for plugging and unplugging the memory stick, while avoiding interference with other components on the mainboard and the hippocampus on the memory stick plug-in position.

[0010] A further improvement of the present invention is that a first reinforcing rib is provided on a side surface of the support plate close to the memory module and on a top surface of the support base, thereby increasing the strength of the connection structure between the support plate and the support base.

[0011] A further improvement of the present invention is that support feet are provided below the support base to increase the clearance between the support base and the bottom surface of the support plate and the underlying mainboard. The support feet are positioned above the mounting holes of the underlying mainboard and increase the clearance between the support base and the support plate and the mainboard, thereby preventing interference with components on the mainboard.

[0012] A further improvement of the present invention is that a bolt hole is provided on the support seat; the bolt hole passes through the support foot, and the support block body can be fixed to the main board by fasteners.

[0013] A further improvement of the present invention is that the bolt hole is a countersunk hole structure, so that the original bolt of the mainboard can be used to pass through the bolt hole, and the countersunk hole structure helps to allow an operating tool to enter the countersunk hole to tighten the bolt.

[0014] A further improvement of the present invention is that the support plate is provided with weight-reducing holes, thereby optimizing the overall structural weight of the support plate.

[0015] A further improvement of the present invention is that a second reinforcing rib is vertically provided in the middle of the weight-reducing hole, which helps to improve the structural strength of the support plate.

[0016] A further improvement of the present invention is that the corners of the support block body are all chamfered, which helps to prevent components on the mainboard from being scratched when the support block body is installed.

[0017] A server includes a tray mounted within a chassis. An upper motherboard is mounted on the tray via an upper tray. A lower motherboard is mounted on the chassis via a lower tray. A memory support structure suitable for a dual-layer motherboard is mounted between the lower motherboard and the tray. The top surface of the support plate contacts the bottom surface of the tray to provide support for the upper motherboard.

[0018] A further improvement of the present invention is that upwardly projecting support feet are provided at each end of the lengthwise direction of the top surface of the support plate; and holes are provided in the tray and / or upper tray that are adapted to accommodate and allow the support feet to pass through. The adaptability of the support feet to the holes prevents displacement between the upper portion of the support block body and the tray, thereby preventing the tray from being supported.

[0019] It can be seen from the above technical solution that the beneficial effects of the utility model are: the support block body is supported on the bottom of the upper mainboard which is prone to deformation, thereby preventing the upper mainboard from deforming downward and causing damage to the components on the lower mainboard; the support plate is located on the memory stick side of the lower mainboard, and the two support seats on the support plate extend toward the memory stick side, which can protect the memory stick and ensure the operating space for plugging and unplugging the memory stick, while avoiding interference with other components on the mainboard and the hippocampus head on the memory stick plug-in position.

Specific embodiment

[0029] In order to make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the attached drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.

[0030] Embodiment 1:

[0031] As Figure 1-2 shown, a memory support structure suitable for a double-layer main board includes a main body 100 of a support block installed between an upper main board 310 and a lower main board 210, and the main body 100 of the support block is located at the end of the length direction of the memory slot on the lower main board 210; the main body 100 of the support block includes a support plate 110 respectively abutting against the upper main board 310 and the lower main board 210, and support bases 120 are provided on both sides of the side of the support plate 110 close to the memory slot, and the support bases 120 extend towards the side of the memory slot, and a first avoidance space in a U-shaped structure is formed between the two support bases 120 and the support plate 110 in the horizontal plane.

[0032] A support foot pad 130 capable of increasing the distance between the bottom surfaces of the support base 120 and the support plate 110 and the lower main board 210 is provided below the support base 120. The support foot pad 130 is located above the installation and fixing holes of the lower main board 210, and the support foot pad 130 increases the gap between the support base 120 and the support plate 110 and the main board, avoiding interference with the components on the main board.

[0033] The support base 120 is provided with bolt holes 121 corresponding to the preset mounting holes on the lower mainboard 210; the bolt holes 121 pass through the support feet 130. Bolts are connected to the mounting holes of the mainboard through the bolt holes 121 to fix the support block body 100.

[0034] The support block body 100 is supported on the bottom of the upper main board 310 which is prone to deformation, so as to prevent the upper main board 310 from deforming downward and causing damage to the components on the lower main board 210; since the memory stick is located in the center of the main board, and the middle of the upper main board 310 is the area where the deformation is the greatest, the support block body 100 is arranged at both ends of the length direction of the memory stick plug-in position. Firstly, it can support the area of the upper main board 310 which is prone to deformation; secondly, the memory stick itself is higher and closer to the bottom surface of the upper main board 310, so arranging the support block body 100 around the memory stick plug-in position is helpful to form protection for the memory stick; thirdly, since the memory stick plug-in position is provided with a hippocampus head that can lock the memory stick after insertion, a layout structure that shines on the end of the memory stick plug-in position is formed in the horizontal plane through the first avoidance space, which forms an avoidance for the trajectory occupied by the hippocampus head to avoid interference; and since mounting fixing holes for fixing the motherboard are reserved on both sides of the length direction end of the memory stick plug-in position, the bolt hole 121 on the support base 120 corresponds to the mounting fixing hole on the motherboard, and the support base 120 can be fixed on the motherboard with the help of the original bolt parts, without the need to additionally develop adapter bolts.

[0035] The support feet 130 increase the distance between the bottom surface of the support plate 110 and the bottom surface of the support base 120 outside the support feet 130 and the mainboard, so as to avoid other components on the mainboard.

[0036] Example 2:

[0037] The support block body 100 is located on the lower motherboard 210, along the length of the memory module insertion area. The support plate 110 is parallel to the memory module, and the support base 120 extends toward the side of the support plate 110 near the memory module insertion area, and the support base 120 is located below the area where the hippocampus rotates outward. The support plate 110 and the support base 120 also form a U-shaped structure, providing stable support while preventing interference with the hippocampus.

[0038] Example 3:

[0039] like Figure 2 As shown, the bolt hole 121 is a countersunk structure. The original bolts of the mainboard can be used to pass through the bolt holes 121, and the countersunk structure helps to allow operating tools to enter the countersunk holes to tighten the bolts.

[0040] Example 4:

[0041] like Figure 1 As shown, a first reinforcing rib 140 is provided on a side of the support plate 110 close to the memory module and on the top surface of the support base 120. The first reinforcing rib 140 improves the strength of the connection structure between the support plate 110 and the support base 120.

[0042] Embodiment 5:

[0043] like Figure 1 As shown, the support block body 100 is a zinc alloy injection molding structure, which helps to improve the overall structural strength of the component and is easy to process and manufacture. A weight-reducing hole 111 is provided on the support plate 110, which optimizes the overall structural weight of the support plate 110. A second reinforcing rib 112 is vertically provided in the middle of the weight-reducing hole 111, which helps to improve the structural strength of the support plate 110. Since the support plate 110 occupies a larger volume, in consideration of saving consumables, a weight-reducing hole 111 is reserved on the support plate 110 to reduce the overall weight, and the second vertical reinforcing rib 112 is installed in the weight-reducing hole 111 to achieve structural reinforcement after weight reduction.

[0044] Example 6:

[0045] like Figure 1-2 As shown, the corners of the support block body 100 are all chamfered. After the corners are chamfered, the connection between adjacent surfaces forms a transition treatment, which can reduce the chance of the support block body 100 damaging the server components during installation.

[0046] Embodiment seven:

[0047] like Figure 3-6 As shown, a server includes a tray 300 installed in a chassis 400, an upper mainboard 310 is installed on the tray 300 through an upper tray plate 320; a lower mainboard 210 is installed on the chassis 400 through a lower tray plate 200, thereby forming an upper mainboard 310 and a lower mainboard 210 arranged in sequence from top to bottom in parallel with each other in the chassis, so as to complete the overall configuration improvement of the server and meet high configuration requirements.

[0048] The edge of the tray 300 is provided with a folded edge for fixation, and the folded edge completes the detachable installation of the tray 300 in the chassis 400 through fasteners; it not only realizes flexible matching when different configuration requirements arise, but also takes into account the operational convenience of the internal installation of the support block body 100 to ensure the installation accuracy of the support block body 100.

[0049] The support block body 100 is installed between the lower mainboard 210 and the tray 300. The top surface of the support plate 110 contacts the bottom surface of the tray 300, providing support for the upper mainboard 310. The two ends of the top surface of the support plate 110 along its length are each provided with upwardly protruding support feet 150, each with a flat top surface. The tray 300 is provided with holes 330 that are compatible with and allow the support feet 150 to pass through. By adapting the supporting top foot 150 and the hole 330, the supporting top foot 150 can form a hole 330 passing through the tray 300, which can form a limiting fixation of the tray 300 on the upper part of the support block body 100, avoiding displacement between the upper part of the support block body 100 and the tray 300, thereby affecting the supporting effect on the tray 300; at the same time, the bottom surface of the tray 300 is fitted with the top surface of the support plate 110 between the two supporting top feet 150, so as to cooperate with the enhancement of the supporting effect of the support block body 100 on the bottom surface of the tray 300 and increase the contact area.

[0050] like Figure 7 As shown, the upper tray 320 may also be provided with holes 330, and the holes 330 on the upper tray 320 correspond to the holes 330 on the tray 300, but it is necessary to ensure that the supporting top feet 150 do not interfere with the components on the bottom surface of the upper mainboard 310, so as to form the support while ensuring the normal operation of the mainboard.

[0051] The present invention describes a memory support structure and server suitable for a double-layer motherboard, in which the support block body 100 is supported on the bottom of the upper motherboard 310 which is prone to deformation, to prevent the upper motherboard 310 from deforming downward and causing damage to the components on the lower motherboard 210; the support plate 110 is located on the memory stick side of the lower motherboard 210, and the two support seats 120 on the support plate 110 extend toward the memory stick side, while being able to protect the memory stick and ensure the operating space for plugging and unplugging the memory stick. At the same time, the installation point of the support seat 120 corresponds to the installation and fixing hole of the lower motherboard 210 in the upper and lower directions, to avoid interference with other components on the motherboard and the hippocampus on the memory stick plug-in position.
