[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. The terms "parallel", "perpendicular" and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within the acceptable deviation range, where the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement being discussed and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system).

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] In order to solve the problem in the related art that the expansion card of the server is prone to loosening, resulting in poor fixing effect, the present application provides a server expansion card fixing mechanism and a server.

[0053] like Figures 1 to 13As shown, the server expansion card fixing mechanism includes a bracket 10 and a fixing structure 40. The fixing structure 40 is connected to the bracket 10, and the fixing structure 40 has at least two card slots 431. A card accommodating space 41 is formed between the fixing structure 40, the bracket 10, and the chassis 30. The size of the card accommodating space 41 is adjustable so that the expansion card is located in the card slot 431.

[0054] By applying the technical solution of this embodiment, the connection between the fixing structure 40 and the bracket 10 ensures the stability of the expansion card 60 inside the server, and can prevent the expansion card 60 from being poorly contacted or damaged due to displacement, thereby ensuring the stable operation and data security of the server, thereby solving the problem in the related art that the expansion card of the server is prone to loosening and thus has a poor fixing effect. At the same time, the design of at least two card slots 431 on the fixing structure 40 and the adjustable characteristics of the card accommodating space 41 enable the server expansion card fixing mechanism to adapt to expansion cards 60 of different specifications, including half-height and full-height cards, thereby improving the configuration flexibility and scalability of the server and meeting the needs of different application scenarios.

[0055] Compared with the prior art that uses a planar contact fixing method to fix the expansion card, the expansion card fixing mechanism of this embodiment, through its innovative structural design, not only improves the fixing stability and compatibility of the expansion card, but also simplifies the installation and maintenance process of the expansion card, reduces the maintenance cost of the server, and improves the reliability of the equipment and user satisfaction.

[0056] In other embodiments not shown in the drawings, the fixed structure is connected to the chassis of the server. In this way, the connection between the fixed structure and the server chassis ensures the stability of the expansion card inside the server, can prevent the expansion card from being poorly contacted or damaged due to displacement, ensures the stable operation of the server and data security, and thus solves the problem in the related art that the expansion card of the server is prone to loosening and thus has a poor fixing effect. At the same time, the above-mentioned setting makes the connection position of the fixed structure more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0057] Optionally, the expansion card 60 is a PCIe card.

[0058] like Figure 2 , Figure 4 , Figure 5 , Fig. 9 as well as Fig.10As shown, the bracket 10 has a plurality of first matching portions 12 spaced apart along a preset direction, and the fixing structure 40 includes a first plate 42 and a second plate 43. The first plate 42 is slidably arranged on the bracket 10 along a preset direction, and a second matching portion 421 is arranged on the first plate 42, and the second matching portion 421 can selectively match with at least one first matching portion 12. The second plate 43 is connected to the first plate 42 and arranged at an angle, and a card slot 431 is arranged on the second plate 43. In this way, the bracket 10 is provided with a plurality of first matching portions 12 spaced apart along a preset direction, so that the first plate 42 can be stably matched with the bracket 10 at multiple positions, thereby adapting to expansion cards 60 of different lengths and positions, thereby enabling the server to flexibly support a variety of expansion card layouts, thereby expanding the configuration capabilities of the device.

[0059] Optionally, one of the first mating portion 12 and the second mating portion 421 is a protrusion, and the other of the first mating portion 12 and the second mating portion 421 is a recess; the protrusion can selectively extend into at least one recess to engage with the recess in a limited position. In this way, the mating mechanism of the protrusion and the recess provides precise positioning and a stable fixing effect, ensuring that the expansion card is firmly installed in the card slot 431 formed by the first plate body 42 and the second plate body 43, reducing the problem of poor contact or displacement of the expansion card caused by vibration, thermal expansion and contraction, and enhancing the reliability and stability of the system. At the same time, since the first plate body 42 can slide in a preset direction, the user can easily adjust the position of the fixing structure 40 to adapt to the installation or replacement of different expansion cards 60 without using any tools, simplifying the maintenance operation and improving the maintenance efficiency.

[0060] like Fig. 9 and Fig.10 As shown, the first plate body 42 includes a first plate segment 422 and a second plate segment 423. The first plate segment 422 has two grooves 4221 arranged at intervals, the second plate segment 423 is located between the two grooves 4221, and both ends of the second plate segment 423 are connected to the first plate segment 422; the second matching portion 421 is arranged on the second plate segment 423. And / or, the first plate body 42 includes a first reinforcing rib 424, which is arranged on the second plate segment 423 and is arranged at intervals from the second matching portion 421. In this way, the first plate body 42 adopts a segmented design of the first plate segment 422 and the second plate segment 423, wherein the second plate segment 423 is embedded between the two grooves 4221 of the first plate segment 422. This design can realize the deformation of the second matching portion 421 under the premise of ensuring the overall rigidity of the first plate body 42, thereby realizing the snap-fitting or separation of the first matching portion 12 and the second matching portion 421, and can also prevent unnecessary deformation during the sliding or fixing process, thereby ensuring the durability and long-term stability of the expansion card fixing mechanism.

[0061] In this embodiment, the first plate body 42 includes a first plate segment 422, a second plate segment 423 and a first reinforcing rib 424. The second matching portion 421 disposed on the second plate segment 423 forms an interlocking structure with the first matching portion 12 of the bracket 10. Through the cooperation of the first protrusion and the first recess, the position of the first plate body 42 can be accurately adjusted to ensure that the expansion card can be accurately installed in the preset position. At the same time, the design of the groove 4221 will not affect the sliding performance, thereby improving the installation accuracy and fixing efficiency of the expansion card. At the same time, the provision of the first reinforcing rib 424 further enhances the structural strength and stability of the second plate segment 423, avoiding wear or fatigue that may occur during repeated sliding. The first reinforcing rib 424 is spaced apart from the second matching portion 421, dispersing the force acting on the second plate segment 423, and ensuring the accuracy and functional integrity of the second matching portion 421 in long-term use.

[0062] Optionally, the second matching portion 421 has an inclined guide surface 4211; and / or, a second reinforcing rib 432 is provided on the second plate body 43. In this way, during the disassembly and assembly of the first convex portion and the first concave portion, the inclined guide surface 4211 provides a smooth guiding effect, effectively reducing the friction between the two, and avoiding damage to the first convex portion and the first concave portion during the installation or disassembly process. The provision of the second reinforcing rib 432 significantly enhances the structural strength and rigidity of the second plate body 43, can prevent the second plate body 43 from being deformed during the fixing process, and ensure the long-term stability and reliability of the fixing structure.

[0063] In this embodiment, the second matching portion 421 has an inclined guide surface 4211 , and the second plate body 43 is provided with a second reinforcing rib 432 .

[0064] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the server expansion card fixing mechanism further includes a locking assembly 20. The locking assembly 20 is connected to the bracket 10, and the locking assembly 20 includes a movable locking portion 22, which is used to lock or unlock with the positioning portion 31 of the chassis 30. In this way, the bracket 10 can be locked or unlocked with the chassis 30 through the locking assembly 20, so as to improve the convenience of disassembly and assembly of the two without using tools, which greatly improves the efficiency of server maintenance.

[0065] like Figures 6 to 8As shown, the bracket 10 has a third matching portion 13, and the locking assembly 20 also includes a locking body 21, a positioning structure 23 and a fourth matching portion 24. The positioning structure 23 is arranged on the locking body 21 to limit the matching with the bracket 10. The fourth matching portion 24 is arranged on the locking body 21, and the third matching portion 13 and the fourth matching portion 24 are limited and stopped; and / or, the locking body 21 has a connecting hole 211, and the locking assembly 20 also includes a fastener 25, so as to connect the bracket 10 and the locking body 21 by passing the fastener 25 through the connecting hole 211 and the bracket 10. In this way, through the design of the third matching portion 13 and the fourth matching portion 24 matching, the locking assembly 20 and the bracket 10 can be firmly locked, and the above-mentioned limit stop design can ensure that the locking assembly 20 will not be accidentally disengaged or moved in a high vibration or mobile environment, thereby protecting the stable connection of the expansion card 60 and reducing data transmission failures caused by unstable connection.

[0066] In this embodiment, one of the third matching portion 13 and the fourth matching portion 24 is a convex portion, and the other of the third matching portion 13 and the fourth matching portion 24 is a concave portion, and the convex portion extends into the concave portion and is limited by the concave portion. The connection between the locking component 20 and the bracket 10 is achieved through the fastener 25 and the connecting hole 211. This design allows the user to adjust the position of the locking component 20 as needed to adapt to expansion cards 60 of different specifications, thereby enhancing the versatility and adaptability of the server expansion card fixing mechanism. At the same time, by introducing an innovative matching and connection mechanism between the bracket 10 and the locking component 20 of the expansion card fixing mechanism, not only the structural stability and assembly efficiency of the mechanism are improved, but also the cost control is optimized and the user operation process is simplified.

[0067] Optionally, the fastener 25 is a screw or a bolt.

[0068] like Figure 7 and Figure 8 As shown, the locking body 21 includes a first handle 216. The locking portion 22 is disposed on the first end of the first handle 216; the first handle 216 is flippable to drive the locking portion 22 to engage or separate with the positioning portion 31. In this way, the flippable design of the first handle 216 allows the user to engage or separate the locking portion 22 with the positioning portion 31 through a simple flipping operation without using additional tools, which greatly simplifies the installation and removal process of the expansion card and improves maintenance efficiency and user experience.

[0069] like Figure 7 and Figure 8As shown, the locking body 21 includes a guide sleeve 212, a body 213, a second handle 214 and a connecting arm 215. The guide sleeve 212 is movably sleeved outside the positioning portion 31, the body 213 is arranged on the guide sleeve 212, and the third matching portion 13, the positioning structure 23 and / or the connecting hole 211 are arranged on the body 213. The second handle 214 is arranged on the guide sleeve 212. The two ends of the connecting arm 215 are respectively connected to the first handle 216 and the second handle 214. In the process of operating the second end of the first handle 216 to turn around the connecting arm 215, the first handle 216 drives the locking portion 22 to move. In this way, the guide sleeve 212 is movably sleeved outside the positioning portion 31, providing a smooth guide path for the locking body 21, ensuring the smooth movement of the locking body 21 during the installation and removal process, and at the same time, through the cooperation between the guide sleeve 212 and the positioning portion 31, a high-precision positioning effect is achieved, avoiding the positioning error of the expansion card during the fixing process, and improving the accuracy and efficiency of the installation.

[0070] In this embodiment, the first handle 216 and the second handle 214 are linked by the connecting arm 215, so that the user only needs to operate the second handle 214 to complete the opening and closing action of the locking assembly. The connecting arm 215 is located in the middle of the second handle 214. By setting the locking portion 22 at the end of the second handle 214, the locking and unlocking process is further simplified. The user can complete the fixing or removal of the expansion card 60 with the minimum operating force and the shortest time, which greatly improves the convenience of equipment maintenance and upgrade. At the same time, the setting of the locking portion 22 and the use of the third matching portion 13 and the fourth matching portion 24 enable the expansion card 60 to be quickly and safely fixed in a variety of configurations. The second handle 214 is linked with the first handle 216 through the connecting arm 215, and can quickly adjust the position of the locking assembly 20 so that the second protrusion accurately extends into the second recess to achieve a locked state. On the contrary, the unlocking process is also simple and fast, which significantly reduces the time cost of maintaining the expansion card 60.

[0071] Specifically, the arrangement of the third mating portion 13, the positioning structure 23 and the connecting hole 211 on the main body 213 ensures a firm connection between the locking body 21 and the bracket 10, and can keep the position of the expansion card 60 fixed even in a high vibration environment, thereby improving the stability and reliability of the system.

[0072] like Figure 3As shown, the positioning portion 31 has a flange 311, and the locking portion 22 has an extension plate 221, and the extension plate 221 is used to extend between the flange 311 and the chassis 30 to limit and stop the flange 311. In this way, the design of the extension plate 221 extending between the flange 311 of the positioning portion 31 and the chassis 30 can achieve the limiting and stopping effects in the height direction, ensure the stability of the locking portion 22 in the locked state, and avoid the displacement of the expansion card 60 during long-term use or transportation, thereby improving the stability of the signal transmission of the expansion card 60 and the reliability of the overall system.

[0073] like Figure 7 and Figure 8 As shown, the locking assembly 20 further includes a stop structure 217. The stop structure 217 is located between the second handle 214 and the first handle 216; when the first handle 216 flips around the connecting arm 215, the stop structure 217 is used to limit and stop the first handle 216. In this way, the stop structure 217 plays a role of limiting and stopping between the first handle 216 and the second handle 214, ensuring the precise control of the second handle 214 during the flipping process, preventing the second handle 214 from flipping excessively and affecting the locking effect of the locking assembly 20, preventing misoperation, ensuring the safety and stability of the expansion card 60 in a fixed state, and reducing the fixation failure or equipment damage caused by improper handle position.

[0074] like Fig.11 and Fig.12 As shown, the bracket 10 includes a bracket body 14 and a window 15 disposed on the bracket body 14, and the server expansion card fixing mechanism also includes a baffle 80. The baffle 80 is disposed on the inner side of the window 15 to limit and stop the expansion card. In this way, the baffle 80 is disposed on the inner side of the window 15 and directly acts on the expansion card, which can effectively limit the lateral displacement of the expansion card, ensure the stability of the expansion card inside the server, and maintain good electrical connection even when the server is subjected to external vibration or movement, thereby improving the reliability and stability of system operation.

[0075] like Fig.11 As shown, the window 15 is provided with a first protrusion 152, and the blocking piece 80 has a first recess, and the first protrusion 152 extends into the first recess to limit the first recess. In this way, the first protrusion 152 and the first recess are precisely engaged, so that the blocking piece 80 can be stably installed on the window 15, thereby limiting the lateral displacement of the expansion card at the physical level, and improving the accuracy and stability of the expansion card installation.

[0076] In this embodiment, the limiting stop structure of the first protrusion 152 and the first recess makes the assembly of the baffle 80 intuitive and simple, without the need for complicated alignment or additional fixing tools. The baffle 80 only needs to be placed in place, and the first protrusion 152 will automatically extend into the first recess to complete the installation of the baffle 80, thereby greatly shortening the assembly time.

[0077] like Figures 14 to 17 As shown, the server expansion card fixing mechanism further includes a pressing structure 50, which is rotatably connected to the window 15 or the bracket body 14 to press the baffle 80. In this way, the pressing function of the pressing structure 50 directly acts on the baffle 80, ensuring that the expansion card is reliably fixed in the longitudinal and lateral directions inside the server, reducing the problem of loosening or displacement of the expansion card caused by server vibration or transportation, and enhancing the stability of the operation of the entire server system and the continuity of data transmission.

[0078] In this embodiment, the rotatable connection design between the crimping structure 50 and the window 15 or the bracket body 14 enables maintenance personnel to complete the compression or release of the expansion card only by operating the crimping structure 50 without using additional tools, thereby greatly simplifying the installation and removal process of the expansion card and improving the efficiency of server maintenance and upgrades.

[0079] like Fig.17 As shown, the crimping structure 50 includes a crimping body 55 and an extension arm 56. The extension arm 56 is disposed on the crimping body 55, and extends along the width direction of the baffle 80 to press the baffle 80. In this way, the extension arm 56 extends along the width direction of the baffle 80, and can evenly distribute the pressing force, ensuring that the baffle 80 and the expansion card are stably supported inside the server, avoiding the expansion card from loosening or being damaged due to vibration during operation or transportation, and enhancing the reliability and stability of the system.

[0080] Optionally, there are one or more extension arms 56. When there are multiple extension arms 56, multiple extension arms 56 are arranged at intervals along the width direction of the baffle 80 and / or the width direction of the crimping body 55. In this way, the use of multiple extension arms 56 can distribute the pressing force more evenly, avoid deformation of the baffle 80 or the expansion card caused by single-point pressing, and ensure the stability of the expansion card inside the server and the reliability of the signal connection. At the same time, the above setting makes the number of extension arms 56 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0081] In this embodiment, there are four extending arms 56 , and the four extending arms 56 are arranged at intervals along the width direction of the blocking piece 80 and the width direction of the crimping body 55 .

[0082] It should be noted that the number of the extension arms 56 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the number of the extension arms 56 is two, three, five, six, or more.

[0083] like Fig.15 and Fig.17 As shown, when the crimping structure 50 presses the baffle 80, the surface of the crimping body 55 facing away from the baffle 80 forms a mounting surface. The crimping structure 50 also includes a metal sheet 57. The metal sheet 57 is coated on at least a portion of the mounting surface. In this way, the electromagnetic shielding effect of the metal sheet 57 can reduce the electromagnetic interference inside the server, protect sensitive electronic components from the influence of external electromagnetic fields, and ensure the accuracy of data transmission and the stability of server operation.

[0084] like Fig.11 and Fig.13 As shown, the first protrusion 152 has a mounting hole 151, and the crimping structure 50 includes a crimping body 55 and a boss 54, and the boss 54 is disposed on the crimping body 55. When the crimping structure 50 presses the baffle 80, the boss 54 extends into the mounting hole 151 and is limitedly matched with the mounting hole 151. In this way, the limited match between the boss 54 and the mounting hole 151 can provide additional physical constraints, ensuring that the position of the crimping structure 50 is accurate and unchanged when the baffle 80 is pressed, thereby ensuring the stability of the expansion card and the reliability of the signal connection.

[0085] In this embodiment, the matching design of the boss 54 and the mounting hole 151 simplifies the installation and disassembly process of the crimping structure 50. No additional fasteners or tools are required. The crimping structure 50 only needs to be aligned with the mounting hole 151 on the first protrusion 152, and the boss 54 can be automatically extended and locked, making the assembly process more intuitive and efficient.

[0086] In this embodiment, the crimping body 55 is plate-shaped, and when the crimping structure 50 presses the blocking piece 80, the two ends of the crimping body 55 are respectively stopped by the bracket body 14 and the window 15. In this way, the plate-shaped design of the crimping body 55 and the stoppers at its two ends with the bracket body 14 and the window 15 not only improve the stability and compatibility of the expansion card fixing mechanism, simplify the assembly process, enhance the heat dissipation and electromagnetic compatibility of the server, but also improve the convenience of operation, reduce the manufacturing and maintenance costs, and enhance the safety of the server.

[0087] Specifically, the plate-like design of the crimping body 55 gives it a larger contact area, thereby forming more stable limit stops at both ends, which can effectively prevent the crimping structure 50 from unexpected movement or vibration during server operation or transportation, ensure that the expansion card and the baffle 80 are fixed more stably, and reduce data errors or system failures caused by loose hardware.

[0088] like Fig.13 As shown, the crimping structure 50 includes a third plate 52 and an extension plate 53. The third plate 52 is rotatably connected to the window 15, and the extension plate 53 is connected to one end of the third plate 52 and is set at an angle with the third plate 52. Among them, the extension plate 53 includes a third plate segment 531 and a fourth plate segment 532 that are connected to each other. The fourth plate segment 532 is connected to the third plate 52 through the third plate segment 531. The third plate segment 531 and the fourth plate segment 532 are set at an obtuse angle. The third plate 52 and the fourth plate segment 532 are respectively located on both sides of the third plate segment 531; the sixth matching portion 51 is set on the third plate segment 531. In this way, the flexible rotation of the crimping structure 50 is realized through the rotatable connection design between the third plate 52 and the window 15, so that the compression and release of the expansion card can be easily realized. This design simplifies the installation and removal process of the expansion card, and improves the user's operating experience and equipment maintenance efficiency.

[0089] In this embodiment, the sixth mating portion 51 provided on the third plate segment 531 of the extension plate body 53 cooperates with the fifth mating portion 141 on the bracket 10, providing precise limit when the crimping structure 50 rotates to the locked position. This mechanical stop mechanism ensures the stability and accuracy of the crimping structure 50 in the locked state, and avoids poor contact or hardware damage caused by inaccurate positioning of the expansion card. The crimping structure 50 adopts the angle setting between the extension plate body 53 and the third plate body 52, as well as the position arrangement of the fourth plate segment 532, which cleverly utilizes the space inside the expansion card fixing device, avoids the collision of the crimping structure 50 with other internal components during rotation, and improves the compactness and rationality of the internal layout of the device.

[0090] like Fig.11 and Fig.12 As shown, the bracket body 14 has a fifth mating portion 141, and the fifth mating portion 141 and the sixth mating portion 51 are limited and stopped, thereby providing accurate limit when the crimping structure 50 is rotated to the locked position. This mechanical stop mechanism ensures the stability and accuracy of the crimping structure 50 in the locked state, and avoids poor contact or hardware damage caused by inaccurate positioning of the expansion card. The crimping structure 50 adopts the angle setting between the extension plate body 53 and the third plate body 52, as well as the position arrangement of the fourth plate segment 532, which cleverly utilizes the space inside the expansion card fixing device, avoids the collision of the crimping structure 50 with other internal components during rotation, and improves the compactness and rationality of the internal layout of the device.

[0091] like Fig.11 and Fig.12As shown, the window 15 is provided with a second protrusion 153, so that when the crimping structure 50 is in the first position, the second protrusion 153 is located outside the third plate 52 to limit and stop the third plate 52. In this way, when the crimping structure 50 is in the first position (i.e., the clamped state), the second protrusion 153 is located outside the third plate 52, and through contact with the third plate 52, an additional limit stop is formed for the expansion card, thereby preventing the expansion card from loosening due to vibration or impact during the operation of the server, ensuring the stable connection between the expansion card and the mainboard, and avoiding data transmission errors or performance degradation caused by poor connection.

[0092] In this embodiment, the second protrusion 153 is provided as a limit stop to ensure that the position of the third plate 52 will not move unnecessarily when the expansion card is crimped and fixed, thereby avoiding possible misoperation during the installation or removal of the expansion card, protecting the expansion card and related connectors from damage, and improving maintenance efficiency and server reliability.

[0093] like Figure 1 As shown, the present application also provides a server, including a chassis 30, a mainboard 70, an expansion card 60, and a server expansion card fixing mechanism. The chassis 30 includes a positioning portion 31, and the mainboard 70 is arranged in the chassis 30. The server expansion card fixing mechanism is used to install the expansion card 60 to fix the expansion card 60 on the chassis 30. Among them, the server expansion card fixing mechanism is the above-mentioned server expansion card fixing mechanism.

This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application.
