Description

Technical Field

[0001] The utility model relates to the technical field of servers, in particular to a mounting bracket and a server. Background Art

[0002] Currently, OCP cards are typically installed by plugging them into a connector welded to the motherboard using a plastic slide rail. The most common solution for this type of card is to secure it to the chassis with screws. This typically requires space for screw access, for example, if the chassis cover above the OCP is removable. However, for some models with a non-removable cover or those requiring replaceable expansion modules, this solution is not feasible from an assembly and maintenance perspective.

[0003] Furthermore, the plastic rail structure consumes space for OCP card I / O layouts and the chassis rear window. When the standard OCP card I / O configuration does not meet actual needs, it is necessary to develop a custom OCP form factor card to increase the number of rear I / O interfaces. However, the rear window layout of some high-density storage models is tight, leaving no space for screws or puller structures. Therefore, how to improve the convenience of OCP card installation while also increasing the OCP card interface space and the density of the chassis rear window is a key issue that needs to be addressed. Utility Model Content

[0004] The utility model provides a mounting bracket and a server, which can not only improve the installation convenience of the OCP card, but also effectively increase the OCP card interface space and the density of the chassis rear window.

[0005] In a first aspect, the present invention provides a mounting bracket, which is arranged in a chassis for mounting an OCP card, wherein the mounting bracket includes two side panels and a partition located between the two side panels;

[0006] The two side plates are spaced apart along the first direction, and the two opposite sides of the partition are respectively connected to the two side plates;

[0007] Along the second direction, the partition is located in the middle of the side panels, so that the partition divides the space between the two side panels into a first installation station and a second installation station that are independent of each other, and the first installation station and the second installation station are respectively used to install an OCP card, wherein the second direction is perpendicular to the first direction;

[0008] An elastic block is provided at one end of each side plate, and a protrusion is provided on the side of each elastic block facing away from the other elastic block. The protrusion is used to engage with a slot provided on the chassis to fix the mounting bracket to the chassis.

[0009] The mounting bracket provided by the present invention utilizes a partition to separate the space between the two side panels into two independent first and second installation stations, each of which can be used to install two OCP cards. The side panels also feature elastic blocks with raised portions. When the bracket, with the OCP card installed, is installed in a chassis, the raised portions engage with the chassis's slots, thereby securing the mounting bracket relative to the chassis. To remove the mounting bracket from the chassis, simply press the elastic blocks on the two side panels inward to disengage the raised portions from the slots, thereby separating the mounting bracket from the chassis. This allows tool-free installation and removal, improving assembly efficiency and maintenance convenience. By eliminating the space required for screws or extraction aids, the space available for the OCP card interface is significantly increased. Furthermore, when the mounting bracket is installed in a chassis expansion slot, one mounting bracket can accommodate two OCP cards, increasing the number of OCP cards that can be installed, thereby effectively improving the density of the chassis' rear window.

[0010] In some possible implementations, the side panel is provided with a slide rail structure for installing the OCP card at positions corresponding to the first installation station and the second installation station, respectively. The slide rail structure extends along the third direction and has a notch. The side panel is provided with a first limiting structure for limiting the position of the OCP card at a position corresponding to the notch.

[0011] The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0012] By providing a slide rail structure, the OCP card can be easily installed horizontally in the mounting bracket, so that the slide rail structure can support and fix the OCP card. By providing a first limiting structure, the OCP card and the mounting bracket can be limited in the third direction to ensure that the OCP card can be installed in place.

[0013] In some possible implementation schemes, the first limiting structure includes an elastic hook provided on the side plate, and the elastic hook is used to engage with a bayonet provided on the OCP card.

[0014] By providing an elastic hook, the deformation of the elastic hook is used to generate an elastic reset force, which drives the elastic hook to engage with the bayonet of the OCP card. Not only is the structure simple, but the fixing effect between the OCP card and the mounting bracket can also be ensured.

[0015] In some possible embodiments, the side panel is provided with an opening at a position corresponding to the notch, the elastic hook is arranged in the opening, and a protrusion is provided on the side of the elastic hook facing away from the other elastic hook, and at least a portion of the protrusion protrudes from the surface of the side panel.

[0016] By providing a protrusion on the elastic hook, when the mounting bracket is mounted on the chassis, the chassis can squeeze the protrusion, so that the elastic hook further presses inward against the OCP board, making the OCP board more firmly fixed.

[0017] In some possible implementation schemes, an elastic wall is provided on a side of each side plate facing away from the other side plate, and at least a portion of the elastic wall protrudes from a surface of the side plate.

[0018] By setting an elastic wall on the side panel, when the mounting bracket is installed in the chassis, the chassis can squeeze the elastic wall, and the elastic wall reacts to the chassis through the elastic reset force, so that the elastic wall and the chassis abut against each other, thereby achieving relative fixation of the mounting bracket and the chassis in the first direction.

[0019] In some possible implementation schemes, a second limiting structure is provided at the other end of the side plate opposite to the end where the elastic block is provided, and the second limiting structure is used to limit the position between the mounting bracket and the chassis.

[0020] By providing the second limiting structure, the mounting bracket can be limited in the third direction to ensure that the mounting bracket is installed in place.

[0021] In some possible implementations, the second limiting structure includes a U-shaped groove provided on the side plate, and the U-shaped groove extends along the third direction;

[0022] The chassis is provided with a limiting pin, which is movably arranged in the U-shaped groove along the third direction relative to the U-shaped groove, and is used to abut against the bottom of the U-shaped groove;

[0023] The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0024] The structure of the U-shaped groove and the limiting pins not only facilitates the horizontal pushing of the mounting bracket into the chassis, but also serves to limit the mounting bracket.

[0025] In some possible implementation schemes, a guide surface is provided on a side of the protrusion facing away from the elastic block.

[0026] By providing a guide surface on the protruding portion, the protruding portion can be more easily inserted into the slot of the chassis, thereby improving assembly efficiency.

[0027] In a second aspect, the present invention provides a server, comprising a chassis and a plurality of mounting brackets as described in any possible embodiment of the first aspect;

[0028] The chassis is provided with a plurality of expansion slots, and the expansion slots are respectively provided with card slots on both sides along the first direction;

[0029] The mounting bracket is located in the expansion slot, and the protrusion on the elastic block provided on the side plate is engaged in the slot.

[0030] The server in the present invention provides a card slot in each expansion slot of the chassis, and provides an elastic block on the mounting bracket. The elastic block is provided with a protrusion. When the bracket with the OCP card installed is installed in the chassis, the protrusion can be snapped into the card slot of the chassis, so that the mounting bracket and the chassis are relatively fixed. When the mounting bracket needs to be removed from the chassis, it is only necessary to squeeze the elastic blocks on the two side panels inward so that the protrusion is disengaged from the card slot, and the mounting bracket can be separated from the chassis. As a result, the mounting bracket in the present invention can be installed and disassembled without tools, improving the efficiency of assembly and the convenience of maintenance. Since the space for arranging screws or pullers is eliminated, the space for the OCP card interface can also be effectively increased. In addition, when the mounting bracket is installed in the expansion slot of the chassis, one mounting bracket can install two OCP cards, which increases the number of installable OCP cards, thereby effectively improving the density of the chassis rear window.

[0031] In some possible implementation schemes, a third limiting structure is provided in the expansion slot, and the third limiting structure is used to limit the mounting bracket in the second direction.

[0032] By providing the third limiting structure, the mounting bracket can be limited in the second direction, thereby improving the structural stability of the mounting bracket in the chassis. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Currently, there are two main ways to secure an OCP card: one is to secure the OCP card to the chassis rear window with hand screws, and the other is to clip the OCP card to the chassis rear window using a puller. Both methods require the use of plastic rails, which are typically secured to the chassis bottom or sidewalls with screws or other structures.

[0048] Because plastic rails typically require space for screw access, such as when the chassis cover above the OCP card is removable, plastic rails are not conducive to OCP card assembly and maintenance for some chassis with non-removable covers or models that require replaceable expansion modules.

[0049] Furthermore, plastic rails occupy space for OCP card I / O and the chassis rear panel. When the standard OCP card I / O configuration doesn't meet actual needs, custom OCP form factor cards are needed to increase the number of rear I / O ports. However, the limited rear panel layout of some high-density storage models leaves no room for reusing the screws or ejector locking solutions used for standard cards.

[0050] Based on this, the present invention provides a mounting bracket and server that not only facilitates the installation and removal of OCP cards, but also effectively increases the OCP card interface space and the density of the chassis rear window. The mounting bracket and server are described in detail below with reference to specific embodiments.

[0051] refer to Figure 1 Hezhi Figure 3 The server in the embodiment of the present invention may include a chassis 100 and an OCP card 200 installed in the chassis 100. The chassis 100 is provided with a plurality of expansion slots 110. Adjacent expansion slots 110 are separated by baffles 120, thereby making each expansion slot 110 independent of the others. Each expansion slot 110 has a storage space for accommodating a mounting bracket 300. The mounting bracket 300 can be used to install the OCP card 200. In other words, the OCP card 200 in this embodiment is installed in the expansion slot 110 via the mounting bracket 300.

[0052] refer to Figure 4 The mounting bracket 300 includes a partition 320 and two side panels 310. The two side panels 310 are arranged along a first direction and spaced apart. The partition 320 is located between the two side panels 310, and the two opposite sides of the partition 320 are respectively connected to the two side panels 310. Along the second direction, the partition 320 is located in the middle of the side panels 310. In this case, the partition 320 can separate the space between the two side panels 310 into independent spaces along the second direction. Specifically, the partition 320 has a first surface and a second surface opposite to each other. A first installation station for installing the OCP card 200 is formed between the first surface of the partition 320 and the two side panels 310, and a second installation station for installing the OCP card 200 is formed between the second surface of the partition 320 and the two side panels 310. That is, one mounting bracket 300 can be used to install two OCP cards 200.

[0053] It should be noted that, combined with Figure 2 In this embodiment, the first direction can be understood as the width direction of the OCP card 200 when the OCP card 200 is installed in the chassis 100. The second direction can be understood as the thickness direction of the OCP card 200 when the OCP card 200 is installed in the chassis 100, and the first direction is perpendicular to the second direction.

[0054] Slide rail structures 311 for mounting the OCP card 200 are provided at locations on the side panel 310 corresponding to the first and second installation positions, respectively. Alternatively, it can be understood that the mounting bracket 300 is provided with two slide rail structures 311, which are arranged on either side of the partition 320 along the second direction. Each slide rail structure 311 extends along a third direction, which can be understood as the length of the OCP card 200 when it is installed in the chassis 100. The third direction is perpendicular to both the first and second directions.

[0055] For reference Figure 4 and Figure 5 The OCP card 200 includes a mounting plate 210, which is used not only to carry and secure the components of the OCP card 200 but also to mount the OCP card 200 on the mounting bracket 300. Accordingly, the slide rail structure 311 may include two elongated sliders 3111 spaced apart along the second direction, with a slideway 3112 for accommodating the mounting bar defined between the two elongated sliders 3111. The mounting plate 210 may be positioned within the slideways 3112 on either side along the first direction, respectively. Furthermore, the mounting plate 210 may slide relative to the slideways 3112 along a third direction, thereby enabling the OCP card 200 to be horizontally inserted into the mounting rack.

[0056] The slide rail structure 311 has a notch 312 that separates the slide into two sections in the third direction. A first retaining structure is provided on the side panel 310 opposite the notch 312. When the OCP card 200 slides to a predetermined position within the slide rail 3112, the first retaining structure secures the OCP card 200 to the mounting bracket 300.

[0057] As an optional implementation scheme, please refer to Figure 4 、 Figure 6 and Figure 7 The first limiting structure may include an elastic hook 330 provided on the side panel 310, with a portion of the elastic hook 330 protruding from the inner wall of the side panel 310. Accordingly, the mounting plate 210 is provided with a latch 211 on both sides along the first direction. When the OCP card 200 slides within the slideway 3112, the portion of the mounting plate 210 without the latch 211 can press the elastic hook 330, allowing it to smoothly pass through the position where the elastic hook 330 is provided. When the portion of the mounting plate 210 provided with the latch 211 passes the elastic hook 330, the elastic hook 330 can enter the latch 211 and engage with the latch 211, thereby achieving relative fixation between the OCP card 200 and the mounting bracket 300.

[0058] In actual use, the first and second installation stations can be used selectively. That is, a single mounting bracket 300 can be used to mount only one OCP card 200, or it can be used to mount two OCP cards 200 simultaneously. When the mounting bracket 300 is used to mount only one OCP card 200, the OCP card 200 can be mounted at either the first or second installation station, without limitation. It will be appreciated that the provision of the mounting bracket 300 in the embodiment of the present application increases the number of available installation stations for OCP cards 200. When the rear window density of the chassis 100 needs to be increased, both installation stations on the mounting bracket 300 can be used to mount OCP cards 200.

[0059] In some embodiments, continue to refer to Figure 4 The partition 320 is provided with a plurality of through holes 321 that extend through the partition 320 in the second direction, so that the first installation station and the second installation station are connected through the through holes 321. It is understood that when an OCP card 200 is installed in one of the first and second installation stations, the through holes 321 can serve as ventilation holes. Heat generated by the operation of the OCP card 200 can flow through the through holes 321 to the space in the other installation station and then out of the mounting bracket 300, thereby improving the heat dissipation effect of the OCP card 200. Of course, when OCP cards 200 are installed in both the first and second installation stations, a certain gap can be left between the OCP card 200 and the partition 320, allowing the heat generated by the OCP card 200 to flow through the through holes 321, thereby more conducive to the high-temperature gas to flow out of the mounting bracket 300.

[0060] Further, continue to refer to Figure 4 Each side panel 310 is provided with an elastic block 340 and a second limiting structure at both ends along the third direction, wherein the second limiting structure can be used to limit the mounting bracket 300 and the chassis 100 bracket in the third direction, and the elastic block 340 is used to relatively fix the mounting bracket 300 and the chassis 100.

[0061] As an optional implementation scheme, please refer to Figure 4 and Figure 9The second retaining structure may include a U-shaped groove 350 provided on the side panel 310. When the mounting bracket 300 is installed in the expansion slot 110, the U-shaped groove 350 is positioned inward. The U-shaped groove extends along the third direction, and the notch of the U-shaped groove 350 is located at the end of the U-shaped groove 350 facing away from the elastic block 340. Correspondingly, the two baffles 120 of the expansion slot 110 are each provided with a retaining pin 122. The retaining pin 122 is disposed within the U-shaped groove 350 so as to be movable relative to the U-shaped groove 350 in the third direction. It will be appreciated that when the mounting bracket 300 is pushed into the expansion slot 110 from the outside inward along the third direction, the retaining pin 122 enters the U-shaped groove 350 from the notch of the U-shaped groove 350. When the mounting bracket 300 is moved into position, the retaining pin 122 abuts against the bottom of the U-shaped groove 350, thereby preventing the mounting bracket 300 from moving further into the expansion slot 110.

[0062] The retaining pin 122 can be, for example, an I-pin. The ends of the I-pin are larger than the middle. Based on this, the width of the U-shaped groove 350 can be designed to be larger than the middle of the I-pin, but smaller than the ends. When the mounting bracket 300 is moved, the middle of the I-pin enters the U-shaped groove 350. At this point, the I-pin also serves to limit the mounting bracket 300 in the first direction, preventing it from swaying, thereby better ensuring that the mounting bracket 300 is properly installed.

[0063] For reference Figure 4 、 Figures 8 to 10 Each elastic block 340 has a protrusion 341 on its side facing away from the other elastic block 340. Along the first direction, the protrusion 341 protrudes from the surface of the side panel 310. Each expansion slot 110 has two retaining plates 120 each with a latching slot 121. The latching slot 121 can be located near the notch of the expansion slot 110. When the mounting bracket 300 is pushed into the expansion slot 110 from the outside until the retaining pin 122 abuts the bottom of the U-shaped slot 350, the protrusion 341 can align with the latching slot 121 and snap into place within the latching slot 121, thereby securing the mounting bracket 300 relative to the chassis 100.

[0064] To remove the mounting bracket 300 from the chassis 100, simply squeeze the elastic block 340 inward from both sides of the expansion slot 110 to disengage the protrusion 341 from the slot 121, and then pull the mounting bracket 300 out from the inside. Thus, the mounting bracket 300 in this embodiment can be installed and removed without tools, improving assembly efficiency and maintenance convenience. Furthermore, compared to solutions that utilize screws or pullers, the mounting bracket 300 in this embodiment can save space for screws or pullers, thereby effectively increasing the interface space for the OCP card 200.

[0065] In some embodiments, as Figure 4 As shown, the protrusion 341 is, for example, a square structure, and accordingly, the engaging slot 121 is also a square structure. Furthermore, a guide surface 3411 is provided on the side of the protrusion 341 facing away from the elastic block 340. The guide surface 3411 can be arranged around the protrusion 341. When the protrusion 341 is inserted into the engaging slot 121, the guide surface 3411 can guide the protrusion 341, thereby making it easier for the protrusion 341 to be inserted into the engaging slot 121.

[0066] Further, continue to refer to Figure 4 The side panel 310 has an opening 313 positioned opposite the notch 312, and an elastic hook 330 is disposed within the opening 313. For example, one end of the elastic hook 330 is fixed to the opening 313, while the other end is free, allowing the elastic hook 330 to be squeezed and deformed. Each elastic hook 330 is further provided with a protrusion 360 on the side facing away from the other elastic hook 330, and at least a portion of the protrusion 360 may protrude from the surface of the side panel 310. When the mounting bracket 300 is pushed into the expansion slot 110 from the outside, the baffle 120 of the expansion slot 110 may squeeze the protrusion 360, thereby causing the elastic hook 330 to deform inwardly through the protrusion 360. When the elastic hook 330 engages with the latch 211, the elastic hook 330 and the latch 211 are more firmly abutted against each other, thereby improving the fixing effect between the OCP card 200 and the mounting bracket 300.

[0067] In some embodiments, continue to refer to Figure 4 Each side panel 310 is further provided with an elastic wall 370 on a side facing away from the other side panel 310. One end of the elastic wall 370 is connected to the side panel 310, and the other end is free. In addition, at least a portion of the elastic wall 370 protrudes from the surface of the side panel 310. For example, the side panel 310 is provided with a mounting groove 380. One end of the elastic wall 370 is connected to the inner wall of the mounting groove 380, and the other end protrudes from the surface of the side panel 310.

[0068] like Figure 4 and Figure 9 As shown, when the mounting bracket 300 is pushed into the expansion slot 110, the baffle 120 of the expansion slot 110 can squeeze the elastic wall 370, causing the elastic wall 370 to deform. At this time, the elastic wall 370 generates an elastic restoring force, causing the elastic wall 370 to press the baffle 120 in the opposite direction. In this way, when the mounting bracket 300 is located in the expansion slot 110, the elastic wall 370 abuts the baffle 120, so that the elastic walls 370 on both sides cooperate to limit the mounting bracket 300 in the first direction, preventing the mounting bracket 300 from rocking left and right relative to the chassis 100.

[0069] It is worth noting that the depth of the mounting groove 380 can be less than the thickness of the free end of the elastic wall 370. Even when the baffle 120 squeezes the elastic wall 370 and the elastic wall 370 is squeezed to contact the bottom of the mounting groove 380, it can still ensure that a portion of the free end of the elastic wall 370 is located outside the mounting groove 380. In other words, at least a portion of the free end of the elastic wall 370 can always protrude from the surface of the side panel 310. Therefore, when the mounting bracket 300 is located in the expansion slot 110, the elastic wall 370 can always remain in contact with the baffle 120, thereby improving the relative fixing effect between the mounting bracket 300 and the chassis 100 in the first direction.

[0070] There may be one or more elastic walls 370. When there is one elastic wall 370, the elastic wall 370 may be disposed in the middle of the side plate 310 along the third direction. When there are multiple elastic walls 370, the multiple elastic walls 370 may be evenly distributed along the third direction to balance the force applied to the mounting bracket 300.

[0071] For reference Figure 4 、 Figure 9 and Figure 11 To further enhance the chassis 100's ability to position the mounting bracket 300, a third limiting structure 123 is provided within the expansion slot 110. This third limiting structure 123 can be used to limit the mounting bracket 300 in the second direction. For example, the third limiting structure 123 can include a first limiting group 1231 and a second limiting group 1232 disposed on the baffle 120. The first limiting group 1231 and the second limiting group 1232 are spaced apart along the second direction, and the spacing between the first limiting group 1231 and the second limiting group 1232 is the same as the dimension of the side panel 310 along the second direction.

[0072] When the mounting bracket 300 is pushed into the expansion slot 110, the two side edges of the side plate 310 along the second direction respectively abut against the first limit group 1231 and the second limit group 1232 to ensure that the mounting bracket 300 can move along the preset direction, thereby ensuring that the mounting bracket 300 can be installed in place.

[0073] As an optional embodiment, the first retaining group 1231 may include multiple T-shaped nails 1233 arranged along the third direction, and the second retaining group 1232 may also include multiple T-shaped nails 1233 arranged along the third direction, with the upper and lower T-shaped nails 1233 arranged in a one-to-one correspondence. Multiple T-shaped nails 1233 not only provide stable support for the mounting bracket 300, but also help simplify the structure and facilitate maintenance.

[0074] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
