Description

TECHNICAL FIELD

[0001] The utility model relates to server technical field especially relates to extension card switching mechanism and device. BACKGROUND

[0002] In the field of industrial servers, especially in 2U specification servers, due to height restrictions, extension cards must be installed parallel to the mainboard. To achieve signal connection, a vertically placed adapter plate needs to be added between the mainboard and the extension card. The adapter plate is provided with 2-3 extension slots for inserting the extension card, and the lower end of the adapter plate is inserted into the extension slot of the mainboard, thereby realizing signal communication between the extension card and the mainboard, as shown in Figure 1 .

[0003] For horizontally installed extension cards, the following methods are currently used for fixation:

[0004] 1. Use extension card support 100 for fixation, as shown in Figure 2 , which includes a main body 101 and a key holder 102. The main body is used to fix the adapter plate, and the key holder is used to fix the key of the extension card. After the extension card is inserted into the adapter plate, the key is fixed on the key holder through a screw.

[0005] 2. Since full-length extension cards are only fixed by the key, there is instability, especially when the device vibrates or is impacted, which can easily cause damage. Therefore, it is usually necessary to add a fixing part at the tail of the extension card. The fixing part is first fixed on the reinforced hole at the end of the extension card, and then the tail fixing part is locked on the extension card support through a screw to prevent the extension card from vibrating too much.

[0006] 3. For half-length extension cards, since the tail does not have a reinforced hole, the above tail fixing part cannot be used for reinforcement. The existing solution is to use a shock-absorbing pad made of rubber, plastic or foam to abut and fix from the side of the extension card, but this method requires an additional support to install the shock-absorbing pad, which will occupy the space inside the case.

[0007] Therefore, how to design a fixing structure suitable for both full-length cards and half-length cards is a problem to be solved. INVENTION CONTENTS

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0048] It should also be understood that the terms used herein in the specification and the appended claims are for the purpose of describing particular embodiments and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0049] It should also be further understood that the term "and / or" as used herein in the specification and in the claims, such term is used to allow for a combination of items to be encompassed by the term, such as for example, a combination of items "a" and "b" to be encompassed by the term "a and / or b" or "a and b".

[0050] As shown in the drawings, Figures 3 to 5 The extension card switching mechanism provided by the embodiment of the present application comprises a main support 10 and a movable support 20; the main support 10 is used for connecting with a switching board 31; the movable support 20 comprises a fixed plate 21, a sliding plate 22 and a limiting plate 23; the fixed plate 21 is connected with the main support 10; the sliding plate 22 is arranged on the fixed plate 21 and can slide along the length direction of the fixed plate 21; one end of the limiting plate 23 is rotationally connected with the sliding plate 22, and the other end of the limiting plate 23 is used for connecting with the main support 10; the main support 10, the fixed plate 21 and the limiting plate 23 jointly form a clamping space for clamping the switching board 31 and an extension card 32 on the switching board 31.

[0051] In the embodiment, the main support 10 is used for mounting the switching board 31, and the switching board 31 is provided with a slot 311 for plugging the extension card 32. The movable support 20 is composed of the fixed plate 21, the sliding plate 22 and the limiting plate 23, and an adjustable connecting structure is formed between the three components. The fixed plate 21 is fixedly connected with the main support 10; the sliding plate 22 is arranged on the fixed plate 21 and can reciprocally slide along the length direction of the fixed plate 21 to realize length adjustment; one end of the limiting plate 23 is rotationally connected with the sliding plate 22 and can rotate relative to the sliding plate 22 and finally be fixed with the main support 10. Through the structure design, a clamping space for clamping the switching board 31 and the extension card 32 on the switching board 31 is formed between the movable support 20 and the main support 10.

[0052] In the embodiment, the rotation angle between the limiting plate 23 and the sliding plate 22 is relatively large, which can be 270 degrees. The angle design makes the limiting plate 23 be able to rotate from the initial position parallel to the sliding plate 22 to the working position abutting against the tail of the extension card 32.

[0053] In the embodiment, the clamping of the adapter board 31 and the expansion card 32 on the adapter board 31 refers to a mode of fixing and supporting the adapter board 31 and the expansion card 32 thereon by the space formed by the cooperation of the movable bracket 20 and the main bracket 10. When clamping, the fixed plate 21, the limiting plate 23 and the main bracket 10 abut against different sides of the expansion card 32. Specifically, the clamping is abutting against four sides of the adapter board 31 and the expansion card 32 thereon. This clamping mode not only prevents the expansion card 32 from shaking in a vibrating environment, but also adapts to expansion cards 32 of different length specifications.

[0054] Specifically, as shown in Figure 4 and Figure 5 , the formation of the clamping space is realized by the relative position of the main bracket 10 and the limiting plate 23. When the limiting plate 23 is unfolded relative to the sliding plate 22, the other end of the limiting plate 23 is connected with the main bracket 10, forming a rectangular space. The adapter board 31 and the expansion card 32 thereon are clamped in the rectangular space. The size of the rectangular space can be adjusted by adjusting the position of the sliding plate 22 on the fixed plate 21. When the limiting plate 23 gradually moves away from the end of the fixed plate 21 connected with the main bracket 10 along with the sliding plate 22, the area of the rectangular space gradually increases. This means that the clamping space formed between the main bracket 10 and the movable bracket 20 can be changed by adjusting the sliding plate 22, which can adapt to the installation requirements of expansion cards 32 of different length specifications, improving the versatility and compatibility of the adapter mechanism.

[0055] In an embodiment, as shown in Figures 6 to 9 , the fixed plate 21 is provided with a sliding groove 211; the sliding plate 22 is slidingly connected in the sliding groove 211; and the sliding groove 211 is provided with a stop structure 212 for limiting the movement of the sliding plate 22 perpendicular to the sliding direction thereof.

[0056] In the embodiment, the fixed plate 21 is provided with a sliding groove 211 extending in the length direction thereof, which is a groove structure with a certain depth. The sliding plate 22 is slidingly arranged in the sliding groove 211. To prevent the sliding plate 22 from being pulled out of the sliding groove 211 during sliding, a plurality of stop structures 212 are arranged at the edges of the fixed plate 21 on both sides of the sliding groove 211. These stop structures 212 are uniformly distributed along the length direction of the sliding groove 211, for limiting the displacement of the sliding plate 22 perpendicular to the sliding direction thereof, ensuring that the sliding plate 22 can only move linearly in the sliding groove 211.

[0057] In a specific embodiment, as shown in Figure 8As shown, the opposite edges of the fixed plate 21 extend to form a plurality of protruding structures in the direction of the sliding groove 211, and the protruding structures on the same side are distributed along the length direction of the sliding groove 211. These protruding structures constitute a separation-preventing structure 212. The distance between the opposite protruding structures is smaller than the width of the sliding plate 22, which can effectively prevent the sliding plate 22 from being separated outward during sliding. This separation-preventing structure 212 is simple in design, easy to process, and does not affect the normal sliding of the sliding plate 22 in the sliding groove 211.

[0058] In another specific embodiment, the separation-preventing structure 212 can adopt a groove design. Specifically, the two side walls of the sliding groove 211 are provided with inwardly recessed guide grooves (not shown in the drawings), and the two side surfaces of the sliding plate 22 are correspondingly provided with protruding parts (not shown in the drawings) matching the guide grooves. When the sliding plate 22 is installed in the sliding groove 211, the protruding parts on the two sides of the sliding plate 22 are embedded in the guide grooves, and during sliding, the protruding parts always slide in the guide grooves. This structure design not only prevents the sliding plate 22 from being separated outward, but also provides a guiding effect for the sliding plate 22, making its sliding more stable. The guide grooves can penetrate through the entire length of the sliding groove 211, or can be shorter than the entire length of the sliding groove 211, as long as they can reliably limit the sliding plate 22.

[0059] In an embodiment, as shown in Figure 7a , Figure 7b and Figure 8 , the side walls of the sliding groove 211 are provided with a plurality of positioning holes 213, and the positioning holes 213 are distributed along the length direction of the sliding groove 211. The side surfaces of the sliding plate 22 corresponding to the side walls are provided with elastic tabs 221, and the elastic tabs 221 can be clamped with the adjacent positioning holes 213.

[0060] In this embodiment, the opposite side walls of the sliding groove 211 are provided with a plurality of positioning holes 213, and the positioning holes 213 are distributed along the length direction of the sliding groove 211. The side surfaces of the sliding plate 22 adjacent to the side walls of the sliding groove 211 are provided with elastic tabs 221. When the sliding plate 22 slides in the sliding groove 211, the elastic tabs 221 are pressed by the side walls of the sliding groove 211 and contract inwardly; when sliding to the position of the positioning hole 213, the elastic tabs 221 are popped out outwardly under the action of their own elasticity and clamped into the positioning hole 213, thereby realizing the positioning and fixing of the sliding plate 22 at this position. When the position needs to be changed, the elastic tabs 221 can be pressed inwardly to be separated from the positioning hole 213, and then the sliding plate 22 can be continuously slid and adjusted. The number of the positioning holes 213 is not limited, and the positioning holes 213 can be opened according to actual needs to clamp different sizes of adapter plates and / or expansion cards on the adapter plates.

[0061] In a specific embodiment, as shown in Figure 7a and Figure 7bAs shown, the opposite side of the sliding plate 22 is provided with a relief hole 222. The main function of the relief hole 222 is to provide a contraction space for the elastic sheet 221. The elastic sheet 221 is fixedly connected to the relief hole 222 by a rivet 224 and is made of elastic material. The elastic sheet 221 is in an outwardly expanded state in a natural state and is contracted into the relief hole 222 when subjected to an inwardly pressing force. This design allows the elastic sheet 221 to be freely contracted when subjected to the pressing force of the side wall of the sliding groove 211 and to be timely popped out to achieve positioning when reaching the positioning hole 213.

[0062] In another specific embodiment, as shown in Figures 5 to 8 The positioning hole 213 on the opposite side wall of the sliding groove 211 includes two groups of positioning holes 213, which are respectively arranged near the front end and the rear end of the sliding groove 211. Here, the front end refers to the end portion close to the positioning pin 214, and the rear end refers to the other end portion away from the positioning pin 214. When the sliding plate 22 slides in the sliding groove 211, the elastic sheet 221 first cooperates with the front end positioning hole 213 group, at which time the position of the sliding plate 22 is suitable for installing the half-length expansion card 32; and continues to slide to the rear end positioning hole 213 group, at which time the elastic sheet 221 cooperates with the rear end positioning hole 213 group, at which time the position of the sliding plate 22 is suitable for installing the full-length expansion card 32. Through the arrangement of the front and rear two groups of positioning holes 213, the sliding plate 22 can be stopped and locked at two fixed positions of the half-length card and the full-length card, thereby realizing accurate positioning and fixing of different length specifications of the expansion card 32. This positioning structure design is simple, convenient to operate, and at the same time ensures the accuracy and consistency of the installation position of different specifications of the expansion card 32.

[0063] In an embodiment, as shown in Figure 7a and Figure 7b The outer side of the sliding plate 22 is provided with a sliding assisting rib 223, which is an elongated protruding structure. When it is necessary to adjust the position of the sliding plate 22, the user can push the sliding plate 22 to slide in the sliding groove 211 of the fixed plate 21 by applying force through the sliding assisting rib 223. The provision of the sliding assisting rib 223 provides a clear force point, making the push-pull operation of the sliding plate 22 more labor-saving and convenient.

[0064] In another embodiment, the sliding assisting rib 223 can be arranged at one end of the sliding plate 22, and its length can be designed according to actual needs, for example, it can occupy 1 / 3 to 1 / 2 of the width of one end of the sliding plate 22. The cross section of the sliding assisting rib 223 can be designed as a circular arc shape, which not only ensures sufficient structural strength, but also avoids safety hazards that may be caused by sharp corners. In addition, the surface of the sliding assisting rib 223 can also be designed with anti-slip texture, further improving the gripping effect during operation.

[0065] In an embodiment, as shown in Figures 10 to 12bAs shown, the limiting plate 23 is rotatably connected with the sliding plate 22 through the spring rotating shaft 24. The spring rotating shaft 24 is composed of the fixed shaft 241 at both ends and the spring 242 in the middle. The fixed shaft 241 is a stepped shaft as a whole, including the shaft main body 2411 with a larger diameter and the shaft front end 2412 with a smaller diameter. The shaft front end 2412 is provided with a small inclined angle. The spring 242 is sleeved on the two shaft front ends 2412 to form a complete spring rotating shaft 24. The opposite sides of the end of the sliding plate 22 connected with the limiting plate 23 are provided with cylinders, and a groove (not shown in the drawing) with a certain depth is formed in the middle of the two cylinders as a rotating shaft mounting hole 251. The end of the limiting plate 23 connected with the sliding plate 22 is provided with a cylindrical structure, and the hollow thereof forms a mounting hole 252.

[0066] During installation, the spring rotating shaft 24 is inserted through the mounting hole 252 of the limiting plate 23, and then the shaft main body 2411 at one end of the spring rotating shaft 24 is placed in the rotating shaft mounting hole 251 of the sliding plate 22. By compressing the spring 242, the shaft main body 2411 at the other end is inwardly retracted to shorten the total length of the rotating shaft, and then the shaft main body 2411 at the other end is placed in the rotating shaft mounting hole 251 at the opposite side. When the spring 242 returns to the natural state, the shaft main bodies 2411 at both ends of the rotating shaft pass through the mounting hole 252 of the limiting plate 23 and are fixed in the rotating shaft mounting holes 251 at both sides of the sliding plate 22. This rotating connection structure enables the limiting plate 23 to rotate relative to the sliding plate 22 within a range of 0-270 degrees, which is convenient for installation and operation and can ensure reliability during use.

[0067] In an embodiment, as shown in Figure 6 and Figure 16 the end of the fixed plate 21 close to the main body support 10 is provided with a positioning pin 214, and the main body support 10 is provided with an opening 11 corresponding to the positioning pin 214. The positioning pin 214 can pass through the mounting hole of the key 131 of the expansion card 32 and the opening 11 of the main body support 10 and be clamped with the key 131 and the opening 11, respectively.

[0068] In this embodiment, the end of the fixed plate 21 close to the main body support 10 is provided with a positioning pin 214 in a cylindrical shape. The main body support 10 is provided with an opening 11 corresponding to the positioning pin 214. During installation, the positioning pin 214 can pass through the mounting hole of the key 131 of the expansion card 32 and the opening 11 of the main body support 10 in sequence and be clamped with these holes, so as to stably connect the fixed plate 21, the expansion card 32 and the main body support 10 together.

[0069] In an embodiment, as shown in Figures 12a to 15 the limiting plate 23 is provided with a concave structure for abutting against the expansion card 32 in the clamping space.

[0070] In the embodiment, the limiting plate 23 is made of metal sheet, and the limiting plate 23 is provided with a concave structure for abutting against the expansion card 32, specifically, a reinforcing rib 231 formed by stamping process. The reinforcing rib 231 is in the shape of long strip, and forms a structure with one side raised and the other side recessed. When the limiting plate 23 is rotated to abut against the tail of the expansion card 32, the recessed surface of the reinforcing rib 231 can clamp the tail PCB of the expansion card 32, effectively reducing the displacement of the expansion card 32, especially the full-length card, in the vibration environment, and plays a reinforcing role. In other embodiments, the limiting plate 23 is made of other materials (such as profile or plastic), and the recess (concave structure) can be directly machined, without the corresponding protruding structure.

[0071] In an embodiment, as shown in Figure 7a , Figure 7b and Figure 8 , the limiting plate 23 is provided with a clamping assembly; the sliding plate 22 is provided with a clamping portion 43 matched with the clamping assembly; the clamping assembly and the clamping portion 43 are matched with each other to fix the limiting plate 23 and the sliding plate 22 in a stacked manner.

[0072] In the embodiment, the limiting plate 23 is provided with the clamping assembly, and the sliding plate 22 is correspondingly provided with the clamping portion 43, and the two are matched for use to fix the limiting plate 23 in the position stacked with the sliding plate 22. After being fixed in a stacked manner, the limiting plate 23 and the sliding plate 22 are folded towards each other. Specifically, when the limiting plate 23 is rotated to be parallel to the sliding plate 22, the clamping assembly and the clamping portion 43 are clamped with each other to achieve reliable fixation. When the limiting plate 23 needs to be opened, only a certain external force is needed to separate the clamping assembly and the clamping portion 43. This design not only ensures the reliability of fixation, but also facilitates disassembly and assembly.

[0073] In an embodiment, as shown in Figures 12a to 13b , the clamping assembly includes an abutting groove 41 and an elastic clamping piece 42 arranged adjacent to each other; the clamping portion 43 is in the shape of column, and the clamping portion 43 can be arranged in the abutting groove 41 and clamped by the elastic clamping piece 42.

[0074] In the embodiment, the clamping assembly includes the abutting groove 41 and the elastic clamping piece 42 arranged adjacent to each other. The abutting groove 41 is arranged in the thickness direction of the limiting plate 23. The elastic clamping piece 42 is in the shape of "J" type clamping spring structure, the upper end of which is around the mounting column 44, and the lower end of which is clamped by the clamping protrusion 45. The clamping spring is made of elastic material, and the middle part thereof is communicated with the middle part of the abutting groove 41. The clamping portion 43 on the sliding plate 22 is in the shape of circular truncated cone, and the diameter of the upper end thereof is larger than that of the lower end. When the clamping portion 43 passes through the clamping spring, the clamping spring will be elastically deformed, and then the clamping spring will clamp the clamping portion 43 in the abutting groove 41 after recovering the shape.
