[0051] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

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

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

[0054] 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, can prevent poor contact or damage caused by the displacement of the expansion card 60, ensures the stable operation of the server and data security, and thus solves the problem that the expansion card of the server in the related art is prone to looseness and 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 characteristic of the card accommodation space 41 enable the server expansion card fixing mechanism to adapt to different specifications of expansion cards 60, including half-height and full-height cards, improving the configuration flexibility and expandability of the server and meeting the requirements of different application scenarios.

[0055] Compared with the prior art in which the expansion card is fixed by a flat contact fixing method, the expansion card fixing mechanism of this embodiment not only improves the fixing stability and compatibility of the expansion card through its innovative structural design, 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 device and user satisfaction.

[0056] In other embodiments not shown in the drawings, the fixing structure is connected to the chassis of the server. In this way, the connection between the fixing structure and the server chassis ensures the stability of the expansion card inside the server, can prevent poor contact or damage caused by the displacement of the expansion card, ensures the stable operation of the server and data security, and thus solves the problem that the expansion card of the server in the related art is prone to looseness and has a poor fixing effect. At the same time, the above setting makes the connection position of the fixing 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] Such as Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10As shown, the bracket 10 has a plurality of first mating parts 12 arranged at intervals in a preset direction. The fixing structure 40 includes a first plate body 42 and a second plate body 43. Among them, the first plate body 42 is slidably arranged on the bracket 10 in the preset direction. A second mating part 421 is arranged on the first plate body 42, and the second mating part 421 can be selectively mated with at least one first mating part 12. The second plate body 43 is connected to the first plate body 42 and is arranged at an angle. A card slot 431 is arranged on the second plate body 43. In this way, the bracket 10 is provided with a plurality of first mating parts 12 spaced at intervals in the preset direction, which enables the first plate body 42 to stably cooperate with the bracket 10 at multiple positions, so as to adapt to expansion cards 60 of different lengths and positions. Furthermore, the server can flexibly support variable expansion card layouts, expanding the device configuration ability.

[0059] Optionally, one of the first mating part 12 and the second mating part 421 is a protrusion, and the other of the first mating part 12 and the second mating part 421 is a recess; the protrusion can be selectively inserted into at least one recess for limit mating with the recess. 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 stably installed in the card slot 431 formed by the first plate body 42 and the second plate body 43, reducing problems such as poor contact or displacement of the expansion card caused by factors such as vibration, thermal expansion and contraction, etc., and enhancing the reliability and stability of the system. At the same time, since the first plate body 42 can slide in the preset direction, without using any tools, the user can easily adjust the position of the fixing structure 40 to adapt to the installation or replacement of different expansion cards 60, simplifying the maintenance operation and improving the maintenance efficiency.

[0060] As Figure 9 and Figure 10 shown, the first plate body 42 includes a first plate segment 422 and a second plate segment 423. Among them, 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 mating part 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 an interval from the second mating part 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, where 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 mating part 421 on the premise of ensuring the overall rigidity of the first plate body 42, and then realize the snap-fit or separation of the first mating part 12 and the second mating part 421, and can also prevent unnecessary deformation during sliding or fixing, 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 engaging portion 421 provided on the second plate segment 423 and the first engaging portion 12 of the bracket 10 form an interlocking structure. 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 installed at the preset position accurately and without error. At the same time, the design of the groove 4221 does not affect the sliding performance, improving the installation accuracy and fixing efficiency of the expansion card. Meanwhile, the setting of the first reinforcing rib 424 further enhances the structural strength and stability of the second plate segment 423, avoiding possible wear or fatigue during repeated sliding. The first reinforcing rib 424 and the second engaging portion 421 are arranged at intervals, dispersing the force acting on the second plate segment 423 and ensuring the accuracy and functional integrity of the second engaging portion 421 during long-term use.

[0062] Optionally, the second engaging portion 421 has an inclined guiding 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 guiding 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 installation or disassembly. The setting of the second reinforcing rib 432 significantly enhances the structural strength and rigidity of the second plate body 43, preventing the second plate body 43 from deforming during the fixing process and ensuring the long-term stability and reliability of the fixing structure.

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

[0064] As Figure 1 、 Figure 2 、 Figure 4 and Figure 6 shown, the server expansion card fixing mechanism further includes a locking assembly 20. Among them, the locking assembly 20 is connected to the bracket 10. The locking assembly 20 includes a movable locking portion 22, and the locking portion 22 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, improving the disassembly and assembly convenience between the two without using tools and greatly improving the efficiency of server maintenance.

[0065] As Figures 6 to 8As shown, the bracket 10 has a third mating portion 13, and the locking assembly 20 further includes a locking body 21, a positioning structure 23, and a fourth mating portion 24. The positioning structure 23 is disposed on the locking body 21 to be in limiting cooperation with the bracket 10. The fourth mating portion 24 is disposed on the locking body 21, and the third mating portion 13 and the fourth mating portion 24 are in limiting stop; and / or, the locking body 21 has a connection hole 211, and the locking assembly 20 further includes a fastener 25 to connect the bracket 10 and the locking body 21 by passing the fastener 25 through the connection hole 211 and the bracket 10. In this way, through the design of the cooperation between the third mating portion 13 and the fourth mating portion 24, firm locking between the locking assembly 20 and the bracket 10 can be achieved. The above-mentioned limiting stop design can ensure that in a high-vibration or moving environment, the locking assembly 20 will not accidentally disengage or move, thereby protecting the stable connection of the expansion card 60 and reducing data transmission failures caused by unstable connections.

[0066] In this embodiment, one of the third mating portion 13 and the fourth mating portion 24 is a convex portion, and the other of the third mating portion 13 and the fourth mating portion 24 is a concave portion. The convex portion extends into the concave portion and is in limiting stop with the concave portion. The connection between the locking assembly 20 and the bracket 10 is achieved through the fastener 25 and the connection hole 211. This design allows the user to adjust the position of the locking assembly 20 as needed to adapt to different specifications of the expansion card 60, enhancing the versatility and adaptability of the server expansion card fixing mechanism. At the same time, by introducing an innovative cooperation and connection mechanism between the bracket 10 and the locking assembly 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] As Figure 7 and Figure 8 shown, the locking body 21 includes a first handle 216. Among them, the locking portion 22 is disposed at the first end of the first handle 216; the first handle 216 is flipably disposed to drive the locking portion 22 to be in limiting cooperation with or separated from the positioning portion 31. In this way, the flipable design of the first handle 216 enables the user to drive the locking portion 22 to cooperate with or separate from the positioning portion 31 through a simple flipping operation without using additional tools, greatly simplifying the installation and disassembly process of the expansion card and improving the maintenance efficiency and user experience.

[0069] As Figure 7 and Figure 8As shown, the locking body 21 includes a guide sleeve 212, a body portion 213, a second handle 214, and a connecting arm 215. Among them, the guide sleeve 212 is movably sleeved outside the positioning portion 31, the body portion 213 is provided on the guide sleeve 212, and the third mating portion 13, the positioning structure 23, and / or the connecting hole 211 are provided on the body portion 213. The second handle 214 is provided 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. Among them, during the process of the second end of the first handle 216 flipping 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 guiding path for the locking body 21, ensuring the stable movement of the locking body 21 during the installation and disassembly processes. 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 that occurs during the fixing of the expansion card, and improving the installation accuracy and efficiency.

[0070] In this embodiment, the first handle 216 and the second handle 214 are linked through the connecting arm 215, enabling the user to complete the opening and closing actions of the locking component by only operating the second handle 214. The connecting arm 215 is located in the middle of the second handle 214. By arranging the locking portion 22 at the end of the second handle 214, the locking and unlocking processes are further simplified. The user can fix or disassemble the expansion card 60 with the least operating force and the shortest time, greatly improving the convenience of equipment maintenance and upgrade. At the same time, the setting of the locking portion 22 and the cooperation with the third mating portion 13 and the fourth mating portion 24 enable the expansion card 60 to be quickly and safely fixed under various 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 component 20, enabling the second convex portion to accurately extend into the second concave portion to achieve the locked state. On the contrary, the unlocking process is also simple and fast, significantly reducing the time cost of maintaining the expansion card 60.

[0071] Specifically, the settings of the third mating portion 13, the positioning structure 23, and the connecting hole 211 on the body portion 213 ensure the firm connection between the locking body 21 and the bracket 10. Even in a high-vibration environment, the position of the expansion card 60 can be kept fixed, improving the stability and reliability of the system.

[0072] As Figure 3As shown, the positioning portion 31 has a flange 311, and the locking portion 22 has an extension plate 221. The extension plate 221 is used to extend between the flange 311 and the chassis 30 to limit and stop against 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, ensuring the stability of the locking portion 22 in the locked state, avoiding the displacement of the expansion card 60 during long-term use or handling, and thus improving the stability of the signal transmission of the expansion card 60 and the reliability of the overall system.

[0073] As Figure 7 and Figure 8 shown, the locking assembly 20 further includes a stop structure 217. Among them, the stop structure 217 is located between the second handle 214 and the first handle 216; during the process of the first handle 216 flipping 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 over-flipping and affecting the locking effect of the locking assembly 20, preventing misoperation, ensuring the safety and stability of the expansion card 60 in the fixed state, and reducing the fixing failure or equipment damage caused by improper handle position.

[0074] As Figure 11 and Figure 12 shown, the bracket 10 includes a bracket body 14 and a form 15 provided on the bracket body 14. The server expansion card fixing mechanism further includes a retaining piece 80. Among them, the retaining piece 80 is provided inside the form 15 to be used for limiting and stopping the expansion card. In this way, the retaining piece 80 is provided inside the form 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, improving the reliability and stability of the system operation.

[0075] As Figure 11 shown, the form 15 is provided with a first protrusion 152, and the retaining piece 80 has a first recess. The first protrusion 152 extends into the first recess to limit and stop against the first recess. In this way, the precise fitting of the first protrusion 152 and the first recess can stably mount the retaining piece 80 on the form 15, thereby physically restricting the lateral displacement of the expansion card and improving the installation accuracy and stability of the expansion card.

[0076] In this embodiment, the limiting and stopping structure of the first protrusion 152 and the first recess makes the assembly of the retaining piece 80 intuitive and simple. Without the need for complex alignment or additional fixing tools, only by placing the retaining piece 80 in place, the first protrusion 152 automatically extends into the first recess to complete the installation of the retaining piece 80, greatly shortening the assembly time.

[0077] As Figures 14 to 17 shown, the server expansion card fixing mechanism further includes a crimping structure 50. The crimping structure 50 is rotatably connected to the form 15 or the bracket body 14 for pressing the retaining piece 80. In this way, the pressing function of the crimping structure 50 directly acts on the retaining piece 80, ensuring reliable fixation of the expansion card both longitudinally and laterally inside the server, reducing problems such as loosening or displacement of the expansion card caused by server vibration or transportation during the process, 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 of the crimping structure 50 with the form 15 or the bracket body 14 enables maintenance personnel to complete the pressing or releasing of the expansion card only by operating the crimping structure 50 without using additional tools, greatly simplifying the installation and disassembly process of the expansion card and improving the efficiency of server maintenance and upgrade.

[0079] As Figure 17 shown, the crimping structure 50 includes a crimping body 55 and an extension arm 56. Among them, the extension arm 56 is provided on the crimping body 55, and the extension arm 56 extends along the width direction of the retaining piece 80 to press the retaining piece 80. In this way, the extension arm 56 extends along the width direction of the retaining piece 80, which can evenly distribute the pressing force, ensuring stable support of the retaining piece 80 and the expansion card inside the server, avoiding loosening or damage of the expansion card caused by vibration during operation or transportation, and enhancing the reliability and stability of the system.

[0080] Optionally, the extension arm 56 is one or more. When there are multiple extension arms 56, the multiple extension arms 56 are arranged at intervals along the width direction of the retaining piece 80 and / or the width direction of the crimping body 55. In this way, the use of multiple extension arms 56 can more evenly distribute the pressing force, avoid deformation of the retaining piece 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 signal connection. At the same time, the above setting makes the selection of 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 extension arms 56, and the four extension arms 56 are arranged at intervals along the width direction of the retaining piece 80 and the width direction of the crimping body 55.

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

[0083] As Figure 15 and Figure 17 As shown, when the crimping structure 50 presses the retaining piece 80, a mounting surface is formed on the surface of the crimping body 55 facing away from the retaining piece 80. The crimping structure 50 further includes a metal sheet 57. Among them, the metal sheet 57 is coated on at least part 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] As Figure 11 and Figure 13 As shown, the first protrusion 152 has a mounting hole 151, and the crimping structure 50 includes a crimping body 55 and a convex post 54, and the convex post 54 is arranged on the crimping body 55. Among them, when the crimping structure 50 presses the retaining piece 80, the convex post 54 extends into the mounting hole 151 and is in limit fit with the mounting hole 151. In this way, the limit fit between the convex post 54 and the mounting hole 151 can provide additional physical constraints, ensuring that the position of the crimping structure 50 remains precisely unchanged when pressing the retaining piece 80, thereby guaranteeing the stability of the expansion card and the reliability of signal connection.

[0085] In this embodiment, the matching design of the convex post 54 and the mounting hole 151 simplifies the installation and disassembly process of the crimping structure 50. Without additional fixing parts or tools, only by aligning the crimping structure 50 with the mounting hole 151 on the first protrusion 152, the convex post 54 can automatically extend and lock, making the assembly process more intuitive and efficient.

[0086] In this embodiment, the crimping body 55 is plate-shaped. When the crimping structure 50 presses the retaining piece 80, both ends of the crimping body 55 are respectively in limit stop with the bracket body 14 and the form 15. In this way, the plate-shaped design of the crimping body 55 and the limit stop of both ends with the bracket body 14 and the form 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 performance of the server, but also improve the operation convenience, reduce the manufacturing and maintenance costs, and strengthen the security of the server.

[0087] Specifically, the plate-shaped design of the crimping body 55 enables it to have a larger contact area, thereby forming a more stable limit stop at both ends. This can effectively prevent the crimping structure 50 from moving or vibrating unexpectedly during server operation or transportation, ensure the fixing of the expansion card and the retaining piece 80 is more stable, and reduce data errors or system failures caused by hardware loosening.

[0088] AsFigure 13 As shown, the crimping structure 50 includes a third plate body 52 and an extension plate body 53. The third plate body 52 is rotatably connected to the window body 15, and the extension plate body 53 is connected to one end of the third plate body 52 and is arranged at an angle with the third plate body 52. Among them, the extension plate body 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 body 52 through the third plate segment 531. An obtuse angle is provided between the third plate segment 531 and the fourth plate segment 532. The third plate body 52 and the fourth plate segment 532 are respectively located on both sides of the third plate segment 531; the sixth mating portion 51 is arranged on the third plate segment 531. In this way, through the rotatable connection design of the third plate body 52 and the window body 15, the flexible rotation of the crimping structure 50 is realized, so that the pressing and releasing of the expansion card can be easily achieved. This design simplifies the installation and disassembly process of the expansion card and improves the user operation experience and equipment maintenance efficiency.

[0089] In this embodiment, the sixth mating portion 51 arranged on the third plate segment 531 of the extension plate body 53 cooperates with the fifth mating portion 141 on the bracket 10 to provide 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 the rotation process, and improves the compactness and rationality of the internal layout of the device.

[0090] As Figure 11 and Figure 12 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 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 the rotation process, and improves the compactness and rationality of the internal layout of the device.

[0091] As Figure 11 and Figure 12As shown, a second protrusion 153 is provided on the form 15. When the crimping structure 50 is in the first position, the second protrusion 153 is located outside the third plate body 52 to limit and stop the third plate body 52. In this way, when the crimping structure 50 is in the first position (i.e., the pressing state), the second protrusion 153 is located outside the third plate body 52. By contacting the third plate body 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 motherboard, and avoiding data transmission errors or performance degradation caused by poor connection.

[0092] In this embodiment, by providing the second protrusion 153 as a limit stop, it can be ensured that the position of the third plate body 52 does not move unnecessarily when crimping and fixing the expansion card, thereby avoiding possible misoperations during the installation or disassembly of the expansion card, protecting the expansion card and related connectors from damage, and improving the maintenance efficiency and the reliability of the server.

[0093] As Figure 1 As shown, the present application also provides a server, including a chassis 30, a motherboard 70, an expansion card 60, and a server expansion card fixing mechanism. The chassis 30 includes a positioning portion 31, and the motherboard 70 is disposed within 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.

The description of the above embodiments is only used to help understand the method and its core idea of the present application.
