Description

Technical Field

[0001] The present invention relates to the field of server chassis, and in particular to a board installation component and a chassis. Background Art

[0002] With the rapid development of artificial intelligence (AI) devices, a growing number of hardware acceleration modules for machine learning, deep learning, and high-performance computing have emerged. Many hardware acceleration modules use PCIe (PCIe Express). However, facing the rapidly increasing demand for bandwidth, data, or model parallel processing, PCIe acceleration modules are no longer suitable. Multiple accelerator cards need to be integrated into a server and work in parallel.

[0003] In an AI server, if four or eight accelerator cards are required at the rear of the chassis, the accelerator cards, due to their large size, will leave no space for the InfiniBand (InfiniBand) cards originally located at the rear. In this case, the IB cards need to be placed at the front of the chassis.

[0004] For a 2U server chassis, if the IB card is placed vertically, the chassis will be partitioned, resulting in a weakened overall chassis strength. Therefore, vertical placement of the IB card is not feasible. If the IB card is placed horizontally, sufficient horizontal operating space is required to install the IB card. However, the front of the chassis is also equipped with components such as hard drives and power supplies, which does not leave sufficient operating space, making IB card installation difficult. Summary of the Invention

[0005] Based on the above problems in the prior art, the present invention aims to propose a board installation assembly and chassis, which solves the problems of insufficient operating space and difficulty in installing and removing boards while ensuring the strength of the chassis.

[0006] The present invention provides a board-card installation assembly, the board-card installation assembly comprising:

[0007] The board mounting assembly includes:

[0008] A frame is formed with a space for installing a board, the frame is provided with an opening for connecting the board to the mainboard, the frame is connected to a printed circuit board, the board is connected to the frame by being connected to the printed circuit board, the printed circuit board is provided with a female connector, and the female connector faces the opening of the frame.

[0009] The present invention further provides a chassis, wherein the front panel of the chassis body is provided with an installation slot, and the board mounting assembly is inserted into the installation slot along the length direction and installed inside the chassis body.

[0010] The length direction is consistent with the front-to-back direction of the chassis.

[0011] By adopting the above technical solution, at least one board can be connected to the frame, and the board can be installed or removed by inserting the board installation assembly into the chassis body, thereby making it possible to conveniently install or remove the board without reserving operating space in the chassis, and ensuring the strength of the chassis body.

[0035] In order to more clearly illustrate the above-mentioned objects, features and advantages of the present invention, this section describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. In addition to the various embodiments described in this section, the present invention can also be implemented in other different ways. Without violating the spirit of the present invention, those skilled in the art can make corresponding improvements, modifications and substitutions. Therefore, the present invention is not limited to the specific embodiments disclosed in this section. The scope of protection of the present invention shall be based on the claims.

[0036] In the description of this application, unless otherwise specified or limited, the terms "install," "connect," and "connect" should be understood in a broad sense, and may include, for example, welding, splicing, clamping, riveting, screwing, threading, etc. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0037] like Figures 1 to 5 As shown, the present invention provides a board mounting assembly, which includes a frame 1 having a space formed therein for mounting a board 14. For example, the frame 1 may include a base plate 11, a panel 12, and a cover plate 15. The base plate 11, the panel 12, and the cover plate 15 are fixedly connected together to form a rectangular parallelepiped box having an opening at least at one end. For example, the opening may be located at one end of the frame 1 in the longitudinal direction X.

[0038] The frame 1 can be connected to a printed circuit board 13. For example, the printed circuit board 13 and a card 14 are housed within a housing (frame). The card 14 is connected to the frame 1 by connecting to the printed circuit board 13. The printed circuit board 13 is provided with a female connector 132, which faces an opening in the frame 1. The opening is used to connect the card 14 to the motherboard 3 through the female connector 132 on the printed circuit board 13. The length direction X of the frame 1 can be consistent with the length direction X of the card mounting assembly.

[0039] like Figures 1 to 5 As shown, the base plate 11 can include two substantially perpendicular plate-shaped portions and can be formed from sheet metal. The base plate 11 can also be provided with a rivet nut 111 for mounting the printed circuit board 13. Specifically, screws 17 can be passed through the printed circuit board 13 and screwed into the rivet nut 111, thereby connecting the printed circuit board 13 to the base plate 11. The edges of the base plate 11 can be provided with a hem, which is provided with a slide groove 112. The slide groove 112 extends along the longitudinal direction X of the frame 1 and is used to mount the cover plate 15.

[0040] like Figures 1 to 4 As shown, the panel 12 can be roughly flat, and the panel 12 can be arranged at the end of the frame 1 opposite to the opening, for example, the other end of the frame 1 in the length direction X. The panel 12 can be fixedly connected to the other end of the base plate 11 in the length direction X by a rivet 16. The panel 12 can be provided with a first fixing portion 121, and the first fixing portion 121 is used to fix the wrench 2 to the panel 12. The first fixing portion 121 is away from the rotating shaft of the wrench 2, and the first fixing portion 121 includes a threaded hole. Holes for heat dissipation can also be provided on the panel 12. The panel 12 can also be provided with a positioning groove 113, and the positioning groove 113 can be used to locate the installation position of the board 14.

[0041] It is understood that the frame 1 is not limited to being formed by the base plate 11, the panel 12, and the cover plate 15. It can also be formed by fewer or more panels, as long as an opening is formed on at least one side. The shape of the frame 1 is not limited to a rectangular parallelepiped box and can be adjusted according to actual needs. For example, it can also be a cubic box.

[0042] like Figures 1 to 3 As shown, the printed circuit board 13 can be provided with a card slot 131, into which the board 14 can be inserted. The board 14 can be an IB card (InfiniBand card). It is understood that the board 14 can also be other types of boards, such as PCIe cards. The printed circuit board 13 can be provided with a female connector 132, which faces the opening of the frame 1, so that the female connector 132 can be connected to a receiving portion, such as the male connector 31 of the motherboard 3.

[0043] like Figure 2 As shown, the board 14 can be provided with a baffle 141. When the board 14 is inserted into the slot, the baffle 141 also inserts into the positioning slot 113 on the panel 12, thereby positioning the board 14 in the installation position and ensuring that the board 14 is securely installed. The printed circuit board 13 can have multiple slots 131, so that the printed circuit board 13 can accommodate multiple boards 14, for example, two boards 14. This allows multiple boards 14 to be installed or removed at once through the board installation assembly, improving operational efficiency.

[0044] It can be understood that with the help of the printed circuit board 13, the board 14 can be kept in a horizontal position, so that the strength of the chassis is guaranteed. The installation method of the board 14 is changed by relying on the connector female head 132 of the printed circuit board 13, which solves the problem of difficulty in installing and removing the board 14.

[0045] like Figure 1 As shown, the cover 15 may include two plate-like parts that are approximately perpendicular to each other. The cover 15 may be formed by sheet metal, and the cover 15 and the base plate 11 have approximately the same shape. The cover 15 may be provided with a locking portion 151 that can cooperate with the slide groove 112 on the base plate 11. For example, the locking portion 151 may be a T-pin. The T-pin is embedded in the slide groove 112 and slides along the slide groove 112 to define the installation position of the cover 15. The cover 15 and the base plate 11 are connected together. The cover 15 can be connected to the panel 12 by screws 17. The cover 15 may also be provided with an observation hole 152, through which the installation status of the board 14 can be observed. The observation hole 152 may be a strip-shaped hole extending along the length direction X of the frame 1.

[0046] like Figure 4 and Figure 5 As shown, the board mounting assembly 100 may further include a wrench 2, which is rotatably connected to the frame 1. The wrench 2 may be in the shape of an elongated strip, one end of which is rotatably connected to the base plate 11, and the other end of the wrench 2 is provided with a second fixing portion 21, which may include a through hole. The wrench 2 can be switched between a first position and a second position by rotation. When the wrench 2 is in the first position, it is attached to the frame 1. When the wrench 2 is in the second position, it may be partially separated from the frame 1 or separated at an angle, forming an angle such that the wrench 2 is in an open state. For example, when the wrench 2 is in the second position, it may be arranged at approximately 30 degrees, 45 degrees, or 60 degrees to the frame 1. Figure 4 The middle wrench 2 is in the first position. When the wrench 2 is in the second position, it can extend generally along the direction of the dotted line a. The second fixing portion 21 and the main body of the wrench 2 are generally perpendicular. When the wrench 2 is in the first position, the main body of the wrench 2 can overlap the frame 1 and be located on the lower side of the bottom plate 11, thereby cleverly storing the wrench 2.

[0047] The wrench 2 does not extend from the chassis body 200 when it is in the first position, and extends from the chassis body 200 when it is in the second position. When the wrench 2 is in the first position, the second fixing portion 21 can face the panel 12, in particular, the first fixing portion 121. The first fixing portion 121 and the second fixing portion 21 can be connected by screws. After the screws are removed, the wrench 2 can be rotated. After the wrench 2 is rotated and opened to the second position, it can form an angle of, for example, 30 degrees, 45 degrees or 60 degrees with the panel 12. By holding the wrench 2, it is convenient to operate the installation and removal of the board mounting assembly. The wrench 2 is set on the opposite side of the opening in the length direction X of the frame 1. By operating the wrench 2, the board mounting assembly can be pushed and pulled, and the opening can be kept facing the receiving portion, such as the male connector 31 of the motherboard 3.

[0048] like Figures 6 to 8 As shown, the present invention also provides a chassis, which can be a server chassis. The chassis can be a 2U chassis, where U is a commonly used unit to represent the height of a server. 1U = 1.75 inches = 44.45 mm, and 2U means the height of the chassis is 88.9 cm.

[0049] The chassis may include a board mounting assembly 100 and a chassis body 200. The chassis body 200 may be in the shape of a rectangular box, with a motherboard 3 disposed therein. Multiple accelerator cards 201 may be disposed at the rear of the chassis, and a power supply 202 and a hard disk 203 may be disposed at the front of the chassis. The front panel of the chassis body 200 may be provided with mounting slots for inserting the board mounting assembly 100. The board mounting assembly 100 may be inserted into the mounting slots and installed in the chassis body 200, for example, by connecting the female connector 132 of the printed circuit board 13 to the male connector 31 of the motherboard 3. This allows for inserting and removing boards without removing, for example, the upper cover of the chassis body 200, thereby facilitating maintenance.

[0050] The size of the frame 1 along its length direction X can be larger than the size of the frame 1 along its height direction and width direction. The frame 1 can be reasonably arranged inside the chassis body 200 without affecting other components such as the power supply 202 and the hard disk 203.

[0051] The length direction X of the board installation assembly 100 is consistent with the front-to-back direction of the chassis. The board installation assembly 100 is plugged in and out along the front-to-back direction, so that the installation slot can be set in front of the chassis body 200 and the size of the installation slot is small, ensuring the strength of the chassis body 200.

[0052] The male connector 31 and the female connector 132 may require considerable force to securely connect. When installing the board mounting assembly 100, the wrench 2 is rotated and unfolded to the second position. The wrench 2 is then used to push the board mounting assembly to connect the female connector 132 to the male connector 31. This allows for easier operation with the help of the wrench 2. After the board mounting assembly 100 is installed, the wrench 2 can be folded back to the first position and attached to the frame 1, eliminating the need for the wrench 2 to extend beyond the frame 1 and occupy additional space.

[0053] When removing the board mounting assembly 100, there is no need to disassemble the chassis body 200 or open the cover 15. Instead, the screws connecting the wrench 2 to the frame 1 can be loosened, and the wrench 2 can be rotated along the axis and extended to the second position to remove the board mounting assembly 100. After the board mounting assembly 100 is removed from the chassis body 200, the board 14 can be easily removed and replaced, solving the problem of insufficient operating space.

[0054] The installation and removal of the board mounting assembly 100 do not need to be performed inside the chassis body 200 , which can fully utilize the limited space inside the chassis body 200 without affecting the installation of other components, and the board maintenance is also more convenient.

[0055] It should be understood by those skilled in the art that the installation process shown in the above embodiment is exemplary rather than restrictive, and the installation structure involved therein is also exemplary rather than restrictive.
