Description

Technical Field

[0001] This utility model relates to the field of server technology, and in particular to a PCIE fixing device. Background Technology

[0002] In the era of booming cloud computing, the application scale of servers is increasing daily, placing higher demands on their performance, reliability, and ease of maintenance. Among these, the need for lightweight design, component standardization, and tool-free module installation is particularly prominent. Currently, various PCIe card mounting structures have emerged in the market. Traditional designs often use screws to secure the PCIe card after it is inserted into the slot, with the insertion and removal direction parallel to the slot opening. With this type of structure, replacing the PCIe card requires first disconnecting the server power, then pulling the card out of the rack, opening the top cover to unlock the card clamping mechanism, and then pulling it upwards. This cumbersome process fails to meet the needs of efficient maintenance. Utility Model Content

[0035] See Figures 1 to 9 As shown, this utility model discloses an embodiment of a PCIe fixing device, including an outer bracket 1, an inner bracket 2, a handle 3, a transmission plate 4, and a PCIe card 5; the PCIe card 5 is installed on the inner bracket 2; the inner bracket 2 is slidably connected to the outer bracket 1 along a first direction; the transmission plate 4 is slidably connected to the outer bracket 1 along a second direction and extends between the outer bracket 1 and the inner bracket 2; the handle 3 is connected to the transmission plate 4 and extends between the outer bracket 1 and the inner bracket 2; the transmission plate 4 is provided with at least one inclined groove 41, and the inner bracket 2 is connected to a transmission shaft 21; the transmission shaft 21 is slidably connected to the inclined groove 41.

[0036] Specifically, the PCIE fixing device of this utility model uses a handle 3 to drive the transmission plate 4, which cooperates with the transmission shaft 21 through the inclined groove 41 to convert the push-pull movement of the handle 3 in the first direction into the movement of the PCIE card 5 in the second direction, realizing tool-free quick installation and removal without disassembling the entire server; and by changing the insertion and removal direction, the operation can be completed in the original position of the rack, greatly improving maintenance efficiency.

[0037] When installing PCIe card 5, first install PCIe card 5 onto the inner bracket 2. Then, by pushing handle 3 inward, handle 3 causes the transmission plate 4 to slide in the second direction. Since the transmission plate 4 has a groove 41, the transmission shaft 21 connected to the inner bracket 2 is slidably connected to the groove 41. As the transmission plate 4 slides, the transmission shaft 21 slides within the groove 41, thereby causing the inner bracket 2 to slide in the first direction, accurately installing the PCIe card 5 into the predetermined position. For disassembly, simply reverse the operation of handle 3.

[0038] This structural design simplifies and streamlines the installation and removal of PCIe 5 cards, eliminating the need for additional tools and reducing operation time and complexity. Simultaneously, the precise transmission design ensures accurate PCIe 5 card placement, improving the stability of the connection between the PCIe 5 card and the server and reducing issues such as poor contact caused by improper installation. Furthermore, this structure allows for simple and quick removal and replacement of the PCIe 5 card without powering down the server, improving efficiency while ensuring equipment safety. It eliminates the need to remove the top cover, and within the server rack, it eliminates the need to power off or pull out the chassis, enabling direct maintenance of the PCIe 5 card from either the front or rear, and facilitating hot-swapping.

[0039] It is understood that in this embodiment, the first direction is vertical, corresponding to the insertion direction of the PCIe card 5; the second direction is horizontal, corresponding to the push-pull direction of the handle 3; the front end of the inclined groove 41 is inclined downwards, and the end is inclined upwards, and the appropriate angle can be set as needed. This orientation setting conforms to ergonomic principles, making the operator's action of pulling the handle 3 in the horizontal direction more natural and smooth, reducing the difficulty of operation and improving work efficiency. By adjusting the angle of the inclined groove 41, the vertical movement distance and speed of the inner bracket 2 can be flexibly controlled, achieving precise adjustment of the PCIe card 5 installation process and adapting to the installation requirements of different specifications of PCIe cards 5. The coordination of the horizontal and vertical directions makes the bracket structure more reasonable in spatial layout, reduces the space occupied, improves the internal space utilization of the equipment, and provides convenience for the installation and wiring of other components.

[0040] See Figure 6In one specific embodiment, the inner support 2 is provided with at least one first slide groove 22 along the first direction, and the outer support 1 is connected to a first fixed shaft 11, and the first fixed shaft 11 is slidably connected to the first slide groove 22.

[0041] Specifically, the design principle is to use the cooperation between the first sliding groove 22 and the first fixed shaft 11 to provide guidance and support for the sliding of the inner support 2 in the first direction, so as to ensure that the sliding of the inner support 2 is stable and accurate.

[0042] When the inner bracket 2 slides along the first direction, the first fixed shaft 11 slides within the first slide groove 22. The first slide groove 22 restricts and guides the first fixed shaft 11, ensuring that the inner bracket 2 can only slide along the predetermined first direction. This prevents the inner bracket 2 from shifting or shaking during the sliding process, thus ensuring the accuracy of the PCIE card 5 installation position.

[0043] This connection structure further improves the stability and precision of the sliding of the inner bracket 2, making the installation of the PCIe card 5 more reliable. At the same time, the simple design of the slide groove and fixed shaft reduces manufacturing and maintenance costs, and improves the bracket's versatility and maintainability.

[0044] See Figure 7 As shown, in one specific embodiment, the transmission plate 4 is provided with at least one second slide groove 42 along the second direction, the outer bracket 1 is connected to a second fixed shaft 12, and the second fixed shaft 12 is slidably connected to the second slide groove 42.

[0045] Specifically, its design principle is similar to the connection structure between the inner support 2 and the outer support 1. Through the cooperation between the second sliding groove 42 and the second fixed shaft 12, it provides guidance and support for the sliding of the transmission plate 4 in the second direction, ensuring the stability and accuracy of the sliding of the transmission plate 4.

[0046] When the handle 3 is pulled to slide the transmission plate 4 in the second direction, the second fixed shaft 12 slides within the second slide groove 42. The second slide groove 42 restricts and guides the second fixed shaft 12, ensuring that the transmission plate 4 can only slide along the predetermined second direction, thereby ensuring that the inclined groove 41 on the transmission plate 4 can accurately cooperate with the transmission shaft 21 on the inner bracket 2, so as to realize the accurate movement of the inner bracket 2.

[0047] This connection structure improves the stability and precision of the sliding of the transmission plate 4, thereby ensuring the reliability of the entire support transmission system. The simple structural design reduces costs and improves versatility and maintainability.

[0048] See Figures 1 to 5 As shown, in one specific embodiment, the outer bracket 1 is connected to a limiting seat 13 at one end near the handle 3, and the handle 3 is detachably connected to the limiting seat 13.

[0049] Specifically, its design purpose is to fix the handle 3 to the limit seat 13 when the PCIe card 5 is in the connected state and working normally, so as to prevent accidental movement from affecting the connection stability of the PCIe card 5; when it is necessary to install or remove the PCIe card 5, the connection between the handle 3 and the limit seat 13 can be quickly released, making it easier to operate the handle 3 to drive the transmission plate 4.

[0050] When the PCIe card 5 is working normally, the handle 3 is securely connected to the limit seat 13. The limit seat 13 provides stable support for the handle 3, ensuring that the handle 3 will not move due to external vibration or accidental contact. When it is necessary to install or remove the PCIe card 5, disconnect the handle 3 from the limit seat 13, and the operator can freely pull the handle 3 to perform the installation or removal operation. After the operation is completed, reconnect the handle 3 to the limit seat 13 to restore the stable working state of the PCIe card 5.

[0051] This detachable connection structure makes switching between the working and installed states of the PCIe 5 card more flexible and convenient. While ensuring the normal working stability of the PCIe 5 card, it reduces the difficulty of installation and removal operations, improves work efficiency, and meets the needs of different usage scenarios.

[0052] In one specific embodiment, the handle 3 is connected to a rotating member 31, and the rotating member 31 is connected to a directional locking pin 32; the limiting seat 13 is provided with a bonding channel 131; the directional locking pin 32 passes through the bonding channel 131 and extends into the inner side of the limiting seat 13; when the directional locking pin 32 rotates circumferentially to a first angle, the outer contour surface of the directional locking pin 32 matches the gap with the inner wall of the bonding channel 131.

[0053] Specifically, when it is necessary to connect or disconnect the handle 3 to the limiting seat 13, rotate the rotating component 31 to rotate the directional locking pin 32 circumferentially to the first angle. At this time, the gap between the outer surface of the directional locking pin 32 and the inner wall of the bonding channel 131 is appropriate, and the directional locking pin 32 can smoothly pass through the bonding channel 131 and extend into or out of the limiting seat 13, completing the connection or separation operation between the handle 3 and the limiting seat 13. When the PCIE card 5 is working normally and it is necessary to fix the connected handle 3 to the limiting seat 13, operate the rotating component 31 again to make the directional locking pin 32 deviate from the first angle. The outer surface of the directional locking pin 32 no longer matches the inner wall of the bonding channel 131, thereby firmly locking the handle 3 on the limiting seat 13 and preventing it from rotating accidentally.

[0054] This locking structure enables convenient control of the connection, locking, and release of the handle 3 and the limit seat 13 through a simple angle rotation operation. It is easy to operate and provides a reliable locking effect. It effectively prevents the handle 3 from accidentally rotating during normal operation of the PCIe card 5, providing a stable working environment for the PCIe card 5 and improving the safety and stability of the bracket operation.

[0055] See Figures 1 to 6 As shown, in a specific embodiment, the inner bracket 2 includes a first connecting plate 23, a support plate 24, and a support assembly 25; the support plate 24 is slidably connected to the outer bracket 1; the first connecting plate 23 and the support assembly 25 are respectively connected to both ends of the support plate 24; one end of the PCIE card 5 is connected to the first connecting plate 23, and the other end is connected to the support assembly 25.

[0056] Specifically, this embodiment innovates the structural design of the inner bracket 2, dividing it into three functional modules: a first connecting plate 23, a support plate 24, and a support assembly 25. The support plate 24 is slidably connected to the outer bracket 1, ensuring that the inner bracket 2 can move smoothly along the first direction. The first connecting plate 23 and the support assembly 25 are respectively connected to both ends of the support plate 24, forming a stable support frame. The two ends of the PCIe card 5 are respectively connected to the first connecting plate 23 and the support assembly 25. This structural design allows the PCIe card 5 to obtain more balanced support force during installation, effectively reducing the risk of damage caused by uneven force at a single point.

[0057] When installing PCIe card 5, first reliably connect one end of PCIe card 5 to the first connecting plate 23, and securely fix the other end to the support assembly 25. When the operator drives the transmission plate 4 through the handle 3, causing the support plate 24 to move in the first direction, the first connecting plate 23 and the support assembly 25 move synchronously as a whole, ensuring that PCIe card 5 can be accurately inserted into the corresponding slot. The disassembly process is the reverse of the installation process; by moving the inner bracket 2 in the opposite direction, PCIe card 5 is smoothly disengaged from the slot.

[0058] This structural design significantly improves the stability and reliability of PCIe card 5 installation. By supporting the card at both ends, the weight of the PCIe card 5 and the vibration generated during operation are effectively distributed, reducing pressure on the slot and extending the lifespan of both the PCIe card 5 and the slot.

[0059] See Figure 6 As shown, in a specific embodiment, the limiting seat 13 is provided with a horizontal positioning hole 132, and the first connecting plate 23 is connected to a positioning member 231 at one end near the limiting seat 13; when the inner bracket 2 slides along the first direction, the positioning member 231 extends into or out of the horizontal positioning hole 132.

[0060] Specifically, the design utilizes the mechanical cooperation between the horizontal positioning hole 132 and the positioning element 231 to provide a clear positional reference for the installation process of the PCIE card 5, ensuring that the PCIE card 5 can accurately reach the predetermined installation position.

[0061] When installing PCIe card 5, the operator drives the inner bracket 2 to slide along the first direction using handle 3. During this process, the positioning element 231 on the first connecting plate 23 gradually approaches the horizontal positioning hole 132 of the limiting seat 13 as the inner bracket 2 moves. When PCIe card 5 approaches the installation position, the positioning element 231 accurately extends into the horizontal positioning hole 132, forming a mechanical lock. At this time, PCIe card 5 is exactly in the correct installation position, completing precise positioning. When removing PCIe card 5, the handle 3 is operated in the opposite direction, the inner bracket 2 moves PCIe card 5, and the positioning element 231 extends out of the horizontal positioning hole 132, releasing the positioning constraint and facilitating the smooth removal of PCIe card 5.

[0062] This structure effectively improves the installation accuracy of the PCIe 5 card, reduces problems such as poor contact caused by installation deviations, and ensures a reliable connection between the PCIe 5 card and the slot. The cooperation between the positioning element 231 and the horizontal positioning hole 132 enhances the stability of the PCIe 5 card after installation, enabling it to withstand external interference such as vibration and impact during device operation, reducing the risk of the PCIe 5 card becoming loose or shifting, extending the service life of the PCIe 5 card, and also improving the reliability of the entire computer system.

[0063] See Figure 6 , Figure 8 and Figure 9 As shown, in a specific embodiment, the inner support 2 is provided with a plurality of first adjustment holes 26 along the second direction, the support component 25 is detachably connected to any of the first adjustment holes 26 through a first connector 27, and the support component 25 is slidably connected to the first connector 27 along the second direction.

[0064] Specifically, the support assembly 25 can be adjusted in the second direction position by the cooperation of the first adjustment hole 26 and the first connector 27 to adapt to the installation requirements of PCIe cards 5 of different lengths.

[0065] When installing PCIe cards 5 of different lengths, the support component 25 is connected to the first adjustment hole 26 at a suitable position on the inner bracket 2 via the first connector 27, according to the length of the PCIe card 5, to achieve the initial adjustment of the position of the support component 25; then, the support component 25 is slid relative to the first connector 27 according to the actual situation, so as to fine-tune the position of the support component 25 relative to the first connector 27, so as to accurately adjust the distance between the support component 25 and the PCIe card 5; finally, the first connector 27 is tightened again to ensure that the support component 25 stably supports the PCIe card 5.

[0066] This adjustable structure enhances the versatility and flexibility of the bracket, accommodating various PCIe cards of different lengths. Users can easily and quickly adjust the position of the support component 25 according to the actual length of the PCIe card, without needing to replace the bracket, reducing operating costs and improving device compatibility.

[0067] In one specific embodiment, the support assembly 25 includes a first support member 251 and a second support member 252. The first support member 251 is slidably connected to the first connector 27. The first support member 251 is provided with at least one second adjustment hole 2511 along a first direction. The second support member 252 is detachably connected to any of the second adjustment holes 2511 through a second connector 253, and the second support member 252 is slidably connected to the second connector 253 along the first direction. The end of the PCIE card 5 away from the first connector plate 23 is installed between the first support member 251 and the second support member 252.

[0068] Specifically, this structure addresses the varying heights of the PCIe card 5 by connecting the second support member 252 to the second adjustment holes 2511 at different positions on the first support member 251, thereby achieving an initial adjustment of the second support member 252's position in the first direction. Then, by utilizing the relative sliding of the second support member 252 relative to the second connector 253, the distance between the second support member 252 and the PCIe card 5 is finely adjusted, thus better adapting to the support requirements of the PCIe card 5 at different heights.

[0069] After adjusting the support component 25 in the second direction, based on the actual height of the PCIe card 5, the second support component 252 is connected to the second adjustment holes 2511 at different positions on the first support component 251 via the second connector 253, thereby completing the initial adjustment of the position of the second support component 252 in the first direction. Then, according to the specific installation of the PCIe card 5, the second support component 252 is slid relative to the second connector 253 to fine-tune the position of the second support component 252 relative to the second connector 253, so as to precisely control the distance between the second support component 252 and the PCIe card 5, ensuring that the second support component 252 can accurately support the PCIe card 5, and finally the second connector 253 is tightened again.

[0070] This structure further enhances the adjustability of the support component 25, enabling it to more flexibly adapt to the support needs of PCIe cards 5 of different heights. It significantly improves the versatility and applicability of the bracket, providing more precise and stable support for PCIe cards 5 and effectively reducing problems such as damage to PCIe cards 5 or unstable connections caused by improper support.

[0071] In one specific embodiment, the first support member 251 is provided with at least one third slide groove 2512 along the second direction; the first connector 27 is slidably connected to the third slide groove 2512 and detachably connected to any of the first adjustment holes 26; the second support member 252 is provided with at least one fourth slide groove 2521 along the first direction; the second connector 253 is slidably connected to the fourth slide groove 2521 and detachably connected to any of the second adjustment holes 2511.

[0072] Specifically, by adding a third slide groove 2512 and a fourth slide groove 2521, the adjustment mechanism of the support component 25 is further optimized, significantly improving the adaptability and stability of the PCIe fixing device. The third slide groove 2512 allows the first connector 27 to slide freely and be precisely positioned in the second direction. Combined with the coarse adjustment function of the first adjustment hole 26, a two-level adjustment system of "coarse adjustment + fine adjustment" is formed, which can achieve millimeter-level precision adjustment for PCIe cards 5 of different lengths, ensuring a perfect fit between the support component 25 and the end of the PCIe card 5. The fourth slide groove 2521 works similarly with the second adjustment hole 2511, creating a vertical dimension of precise adjustment capability in the first direction. It can flexibly adjust the support height according to the thickness difference of the PCIe card 5, effectively dispersing stress concentration points. This dual-dimensional slide groove-adjustment hole linkage structure maintains the core adjustment function while reducing adjustment resistance through the introduction of sliding pairs, making operation more convenient. At the same time, the detachable connection method retains maintenance flexibility. When the slide groove is worn, the connector can be replaced separately, extending the overall service life of the bracket. This design organically combines the two originally independent directional adjustments to form a synergistic optimization effect, enabling the bracket to adapt to more PCIe cards and further expanding the product's application scenarios.

[0073] More specifically, both the first support member 251 and the second support member 252 are L-shaped, which can provide stable support for the PCIe card 5, increase the contact area with the PCIe card 5, and evenly distribute the force, effectively preventing the PCIe card 5 from deforming or being damaged due to uneven force. The L-shaped structure can also make full use of space, making it easy to cooperate with other components such as the inner bracket 2 for installation, making the overall bracket structure more compact and reasonable, improving the stability and reliability of the PCIe card 5 after installation, and ensuring its normal operation.

[0074] See Figures 1 to 5 As shown, in a specific embodiment, the outer bracket 1 includes a base plate 14, a second connecting plate 15, and an isolation plate 16. The base plate 14, the second connecting plate 15, and the isolation plate 16 are connected in sequence to form a Π shape. The inner bracket 2 is slidably connected to the base plate 14, and the inner bracket 2, the handle 3, the transmission plate 4, and the PCIE card 5 are located between the base plate 14, the second connecting plate 15, and the isolation plate 16. The isolation plate 16 is provided with a plurality of elastic support portions 161.

[0075] Specifically, the outer bracket 1 is formed by sequentially connecting the base plate 14, the second connecting plate 15, and the isolation plate 16 in a Π shape. This unique structural design provides a stable installation space for the inner bracket 2, handle 3, transmission plate 4, and PCIe card 5. The inner bracket 2 is slidably connected to the base plate 14, allowing the components to be orderly distributed inside the Π-shaped structure. Several elastic support parts 161 provided on the isolation plate 16 utilize the deformation characteristics of the elastic material. When adjacent PCIe mounting devices are used side by side, they make close contact with the corresponding structures of the adjacent devices, fill the gaps, and block the electromagnetic signal propagation path, thereby preventing electromagnetic interference (EMI) between adjacent PCIe slots.

[0076] Once the PCIe card 5 is installed and secured in the inner bracket 2, the entire assembly is located within the Π-shaped space of the outer bracket 1. During operation, if similar securing devices are installed in adjacent PCIe slots, the elastic support 161 on the isolation plate 16 will abut against the adjacent PCIe securing devices. Under pressure, the elastic support 161 undergoes elastic deformation, tightly fitting against the adjacent structural surfaces, completely filling any gaps between the PCIe slots and forming a continuous electromagnetic shielding layer. In this way, even if adjacent PCIe cards 5 generate electromagnetic signals, these signals will be blocked by this shielding layer and cannot propagate to the area where other PCIe cards 5 are located, effectively preventing electromagnetic interference between adjacent slots and ensuring the normal and stable operation of each PCIe card 5.

[0077] The Π-shaped structure of the outer bracket 1 provides robust support and protection for the internal components, optimizes the overall spatial layout, and enhances the structural strength and stability of the bracket. The elastic support 161 significantly improves the PCIe mounting device's resistance to electromagnetic interference in multi-slot environments, effectively preventing signal crosstalk, ensuring the stability and reliability of PCIe card 5 signal transmission, reducing EMI-induced malfunctions and data transmission errors, improving the overall stability and reliability of the computer system, and extending the lifespan of the PCIe card 5 and related equipment.

[0078] Furthermore, the first connecting plate 23 abuts against the second connecting plate 15, and both the first connecting plate 23 and the second connecting plate 15 are provided with heat dissipation holes 232.

[0079] The abutting design of the first connecting plate 23 and the second connecting plate 15 significantly improves the overall structural stability of the PCIe fixing device by increasing the contact area, effectively reducing the risk of component loosening due to vibration or external impact. Furthermore, the presence of heat dissipation holes 232 on both the first connecting plate 23 and the second connecting plate 15 creates an efficient heat conduction path, allowing the heat generated by the PCIe card 5 during operation to be quickly dissipated into the surrounding environment, reducing performance degradation and shortened lifespan caused by excessive temperature. This structural design ensures the reliability of the device operation while improving the working efficiency of the PCIe card 5 through optimized heat dissipation, achieving synergistic optimization of mechanical stability and thermal management performance.

[0080] See Figure 6 and Figure 7 As shown, in one embodiment, a plurality of support columns 6 are provided between the support plate 24 and the substrate 14, the support columns 6 being connected to the support plate 24 and abutting against the substrate 14, and / or, the support columns 6 being connected to the substrate 14 and abutting against the support plate 24.

[0081] Specifically, in the PCIe mounting device, a multi-point support structure is formed by setting several support columns 6 between the support plate 24 and the base plate 14, which significantly enhances the mechanical stability of the structure. This design effectively disperses the vibration and stress generated during the operation of the PCIe card 5, avoids the risk of structural deformation caused by single-point stress, and ensures the smoothness of the sliding process of the inner bracket 2. The setting of the support columns 6 also optimizes the load distribution between the support plate 24 and the base plate 14, reduces material fatigue that may occur due to long-term use, and extends the service life of the device. This structural improvement enhances the overall reliability through a physical support mechanism while maintaining the original function, and is particularly suitable for high-vibration environments or industrial applications with stringent stability requirements.

[0082] See Figure 7 As shown, in a specific embodiment, the substrate 14 is further provided with an elastic protrusion 141, and the transmission plate 4 is provided with a first fixing hole 43 and a second fixing hole 44; when the transmission plate 4 is in the pulled-out state, the elastic protrusion 141 extends into the first fixing hole 43; when the transmission plate 4 is in the pushed-in state, the elastic protrusion 141 extends into the second fixing hole 44.

[0083] In this embodiment, an elastic bump 141 is added to the substrate 14, and a first fixing hole 43 and a second fixing hole 44 are provided at corresponding positions on the transmission plate 4. The elastic bump 141, in conjunction with the first fixing hole 43 and the second fixing hole 44, achieves mechanical locking of the transmission plate 4 in both the pulled-out and pushed-in states. This design is based on the principles of elastic deformation and mechanical limiting, using the elastic restoring force of the elastic bump 141 to provide a stable locking force, ensuring that the transmission plate 4 remains fixed in both the pulled-out and pushed-in positions. This locking structure significantly improves the convenience and safety of the PCIe card removal process.

[0084] In one specific embodiment, the handle 3 is provided with anti-slip holes 33 for easy gripping, to prevent the operator from slipping when gripping the handle 3 and to avoid misoperation.

[0085] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
