[0002] Currently, in the field of high-performance workstations and servers, M.2 hard drives have become the preferred data storage solution due to their superior transfer speeds and compact size. Compared to traditional hard drives, M.2 hard drives communicate directly with the CPU through the PCIe interface, significantly shortening the data transfer path and enabling high-speed read and write operations.

[0038] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Currently, most PCIe devices are designed based on the full-height, half-length PCIe form factor, aiming to provide a more flexible M.2 hard drive installation and removal experience. By setting a dedicated hard drive tray on the PCIe card, users can easily replace M.2 hard drives as if they were replacing regular peripherals, without having to go deep into the workstation for complex operations. However, when it comes to workstation PCs with extremely limited space, this full-height, half-length dual M.2 hard drive quick-swap PCIe card does not provide ideal compatibility.

[0040] like Figures 1 to 6As shown, this application provides a peripheral component interconnect (PCIe) device, including: a PCIe board 1, including a board body 10 and a guide member 11 mounted on the board body 10, the guide member 11 being provided with a guide groove 12; a hard disk assembly 2, which is pluggably mounted in the guide groove 12; the hard disk assembly 2 includes a carrier member 20, a light guide member 30 and an adapter card 40, at least a portion of the carrier member 20 is used to carry the hard disk, the adapter card 40 is disposed on the board body 10 and is used to connect to the hard disk, the light guide member 30 is disposed on at least a portion of the carrier member 20, the end of the light guide member 30 is disposed opposite to the indicator light 41 of the adapter card 40, and at least a portion of the light guide member 30 extends along the extension direction of the carrier member 20.

[0041] Through this application, the M.2 hard drive is first installed into the carrier 20 and connected to the adapter card 40 to form the hard drive assembly 2. Then, the hard drive assembly 2 is assembled with the guide member 11 through the guide slot 12 installed on the PCIe card 1. Finally, the assembled PCIe device is inserted into the PCIe slot of the motherboard, which can realize the quick insertion and removal and maintenance of the PCIe device.

[0042] The design of the guide component 11 and guide slot 12 in this application ensures smooth and precise insertion and removal of the hard drive assembly 2, greatly simplifying the installation and removal process of the M.2 hard drive. This is particularly suitable for work scenarios requiring frequent maintenance or data exchange, such as high-performance workstations and servers, improving system maintenance efficiency and user experience. Furthermore, the light guide component 30 transmits the indicator light 41 signal of the adapter card 40 to the outside, allowing users to directly observe the situation inside the main insertion slot through the light emitted by the light guide component, thus facilitating insertion and removal operations. Additionally, this application adopts a half-height, half-length PCIe device. Compared to the traditional full-height, half-length design, this device is more compact, making it particularly suitable for workstations or servers with limited space. It achieves quick insertion and removal of dual M.2 hard drives without sacrificing space for other components inside the chassis, solving the problem of low insertion efficiency caused by users not being able to see the insertion status inside the insertion slot when inserting hard drives in existing technologies, and improving overall layout flexibility and system integration.

[0043] In this embodiment, the guide groove 12 has a length of 73.5mm-75.5mm, a width of 52.2mm-54.2mm, and a height of 11.7mm-12.7mm; the PCIe board 1 has a length of 167.65mm, a width of 68.9mm, and a height of 14.47mm.

[0044] Specifically, the carrier 20 has a carrier cavity 21 and a hollow part 22 that are interconnected, and the hard disk, light guide 30 and adapter card 40 are all installed in the carrier cavity 21.

[0045] In this embodiment, the light guide 30 is made of a light-transmitting material.

[0046] In this way, the presence of the perforated portion 22 increases the contact area between the inner and outer surfaces of the carrier component 20, promoting air circulation and thus improving heat dissipation efficiency. Especially inside the carrier cavity 21, the heat generated by the hard drive during operation can be quickly dissipated through the perforated portion 22, avoiding the negative impact of high temperature on hard drive performance and lifespan, and ensuring data transmission speed and reliability. Furthermore, the interconnected carrier cavity 21 and the perforated portion 22 design provide space for the installation of the light guide component 30, allowing the indicator light 41 of the adapter card 40 to transmit information directly or indirectly to the user through the light guide component 30 and the perforated portion 22. Even when the device is in a closed state, the hard drive status can be intuitively monitored, improving system manageability and fault response speed.

[0047] Optionally, the cutout portion 22 includes a light-transmitting hole 220, which is positioned opposite to the light guide 30, allowing the light guide 30 to transmit light signals through the light-transmitting hole 220. This allows the light signal from the indicator light 41 of the adapter card 40 to be transmitted to the outside without obstruction, providing intuitive visual feedback. Users can directly observe the situation inside the main body's insertion slot through the light emitted by the light guide, facilitating insertion and removal operations. By directly observing the hard drive status through the light-transmitting hole 220, users can promptly detect potential faults or anomalies, facilitating rapid maintenance and management and avoiding the additional time and cost associated with internal inspections.

[0048] Optionally, the cutout portion 22 includes a heat dissipation hole 221, which is disposed opposite to the hard disk assembly 2, allowing the light guide 30 to dissipate heat through the heat dissipation hole 221. This provides an additional airflow path, aiding in heat dissipation from the hard disk assembly 2. Especially when the hard disk generates significant heat during high-intensity read / write operations, the heat dissipation hole 221 can accelerate heat exchange, maintaining the hard disk within a suitable temperature range, ensuring data transmission stability and extending the hard disk's lifespan.

[0049] It should be noted that, under different usage requirements and actual working conditions, the light guide 30 can also utilize the light-transmitting hole 220 for heat dissipation, and the light guide 30 can also utilize the heat dissipation through hole 221 to transmit light signals. Furthermore, the shapes of the light-transmitting hole 220 and the heat dissipation through hole 221 can be selected accordingly based on different usage requirements and actual working conditions.

[0050] Optionally, there are at least two light guides 30, spaced apart around the periphery of the hard drive. By placing multiple light guides 30 around or on both sides of the hard drive, 360-degree light indication can be provided, allowing users to clearly see the situation inside the host connector slot from any angle. This all-around indication improves the efficiency of monitoring and management in different environments. Furthermore, the multi-point layout of the light guides 30 can independently or in conjunction to display different information, such as the hard drive's health status, data transfer rate, and power status. Through rich changes in light signals, users can gain a more detailed understanding of the hard drive's real-time status and take timely measures to avoid data loss or system failure.

[0051] In this embodiment, there are two light guides 30, which are arranged opposite to each other on both sides of the hard disk.

[0052] Specifically, the light guide 30 has a first end face 31 and a second end face 32 disposed opposite to each other. The first end face 31 is located on the side of the second end face 32 closer to the adapter card 40, and the area of ​​the first end face 31 is larger than the area of ​​the second end face 32. Designing the first end face 31 of the light guide 30 to have a larger area than the second end face 32, and the first end face 31 being closer to the adapter card 40, effectively enhances the reception and diffusion capabilities of light signals. The large area of ​​the first end face 31 can more fully capture the light from the indicator light 41 of the adapter card 40, while the smaller second end face 32 helps to concentrate the light beam and guide it to the outside of the carrier 20, achieving clearer and longer-distance status indication. Especially in low-light environments, this design can significantly improve visibility.

[0053] In this embodiment, at least one of the light guide 30 and the hard drive is detachably mounted on the carrier 20. This arrangement improves the convenience of maintenance and upgrades to some extent. Once the light guide 30 is damaged or needs to be replaced, the user can remove it directly without disassembling the entire hard drive assembly 2. Similarly, when the hard drive reaches the end of its service life or needs to be replaced with a larger capacity hard drive, the old hard drive can simply be removed from the carrier 20 and replaced with a new hard drive without extensive disassembly and reassembly of the entire device. This not only saves maintenance time but also reduces potential damage to other components during operation.

[0054] like Figure 4 As shown, the light guide 30 includes a first guide strip 33 and a second guide strip 34 that are connected to each other along the extension direction of the light guide 30. The first guide strip 33 is located on the side of the second guide strip 34 that is closer to the indicator light 41. The guide cross-sectional area of ​​the first guide strip 33 gradually decreases along the extension direction from the first guide strip 33 to the second guide strip 34. And / or, the guide cross-section of the second guide strip 34 is a constant cross-section.

[0055] Thus, the specific structural design of the light guide 30 utilizes the principle of total internal reflection. As light travels from a large cross-section to a small cross-section, the reflection angle within the light guide 30 gradually increases due to the decreasing cross-sectional size. This ultimately results in a strong light signal output at the end or sides of the light guide 30, improving the transmission efficiency and brightness of the light signal. This ensures that even in low-light environments, users can clearly see the hard drive status indicator. The reduced cross-sectional area design of the first guide bar 33 reduces light scattering during transmission, allowing more light to be guided to the indicated location, reducing waste in the optical path and improving the accuracy and reliability of the status indicator. Simultaneously, this design also helps to focus the light beam, preventing light diffusion within the light guide 30 and ensuring the concentration and directionality of the light signal. The second guide bar 34 employs a uniform cross-section design, which not only reduces manufacturing complexity but also simplifies the installation process of the light guide 30. The uniform cross-section design ensures consistent light transmission performance of the light guide 30 at different positions, making it easy for users to understand and operate. It also facilitates maintenance and replacement of the light guide 30 without the need for complex alignment or adjustment processes.

[0056] In this embodiment, the carrier 20 is provided with a first snap-fit ​​structure, and the light guide 30 is provided with a second snap-fit ​​structure adapted to the first snap-fit ​​structure. One of the first snap-fit ​​structure and the second snap-fit ​​structure is a snap-fit ​​protrusion, and the other of the first snap-fit ​​structure and the second snap-fit ​​structure is a snap-fit ​​groove.

[0057] In the above embodiments, the first and second snap-fit ​​structures cooperate to form a stable physical connection, ensuring the secure installation of the light guide 30 on the carrier 20. Even under equipment vibration or movement, the light guide 30 can be effectively prevented from loosening or falling off, improving the overall safety of the system. Compared with traditional threaded connections or other fastening methods, this greatly simplifies the assembly and disassembly process of the light guide 30. Installation can be completed with simple alignment and pressing actions, without the need for tools, saving installation time and reducing operational difficulty. At the same time, it can be quickly disassembled when the light guide 30 needs to be replaced or maintained, improving the maintenance efficiency of the equipment.

[0058] In this embodiment, the carrier 20 is provided with a positioning groove, which is adapted to the shape of the light guide 30, and the light guide 30 is installed in the positioning groove. This adaptation design between the positioning groove and the shape of the light guide 30 not only simplifies the installation steps but also enhances the modularity of the system. As an independent component, the light guide 30 allows for adjustments to the device's indicator style or color by replacing different light guides, adapting to different usage scenarios and user preferences. Users can directly observe the situation inside the main body's insertion slot through the light emitted by the light guide, facilitating insertion and removal operations without affecting the normal operation of other hardware.

[0059] Specifically, the carrier 20 includes a first connecting plate 23 and a second connecting plate 24 connected at a preset angle. At least a portion of the light guide 30 is adapted to the connection between the first connecting plate 23 and the second connecting plate 24 and installed at the connection between the first connecting plate 23 and the second connecting plate 24. The first connecting plate 23 is provided with a first snap-fit ​​portion, and the light guide 30 is provided with a second snap-fit ​​portion 231 adapted to the first snap-fit ​​portion. One of the first snap-fit ​​portion and the second snap-fit ​​portion 231 is a snap-fit ​​protrusion, and the other of the first snap-fit ​​portion and the second snap-fit ​​portion 231 is a snap-fit ​​groove. And / or, the second connecting plate 24 is provided with a third snap-fit ​​portion 240, and the light guide 30 is provided with a fourth snap-fit ​​portion 241 adapted to the third snap-fit ​​portion 240. One of the third snap-fit ​​portion 240 and the fourth snap-fit ​​portion 241 is a snap-fit ​​protrusion, and the other of the third snap-fit ​​portion 240 and the fourth snap-fit ​​portion 241 is a snap-fit ​​groove.

[0060] In this way, the first connecting plate 23 and the second connecting plate 24 of the carrier 20 are connected perpendicularly to each other. This design provides a spatial basis for optimizing the optical path of the light guide 30. The preset angle ensures that the light propagates along the optimal path after entering the light guide 30, avoiding unnecessary refraction or absorption. This allows the light signal to be transmitted to the user more efficiently and accurately, enhancing the clarity and reliability of the status indication. Furthermore, the user can directly observe the situation inside the main body insertion slot through the light emitted by the light guide, facilitating insertion and removal operations. The light guide 30 is installed at the connection between the first connecting plate 23 and the second connecting plate 24, which is usually the most stable part of the carrier 20. The light guide 30 is tightly integrated with the two plates through a snap-fit ​​structure, which not only strengthens the stability of the light guide 30 itself but also enhances the rigidity of the overall structure through its support at the connection point. Especially when the equipment is subjected to vibration or impact, it can reduce the risk of hardware displacement and improve the durability of the equipment.

[0061] Furthermore, the snap-fit ​​design reduces assembly difficulty during production and simplifies disassembly and assembly procedures during maintenance. In mass production, automated assembly can be achieved, reducing labor costs; while during maintenance, the quick replacement of the light guide component 30 significantly shortens equipment repair time and reduces economic losses caused by downtime.

[0062] Specifically, the carrier 20 includes a carrier plate 25, which forms a carrier cavity 21. The carrier 20 also includes a positioning plate 26 disposed on the carrier plate 25. At least a portion of the positioning plate 26 protrudes from the carrier plate 25 and is located within the carrier cavity 21. The positioning plate 26 and at least a portion of the carrier plate 25 are positioned opposite each other and form a positioning groove that conforms to the shape of the light guide 30. The positioning groove formed by the positioning plate 26 and at least a portion of the inner wall of the carrier plate 25 provides a precise installation position for the light guide 30, ensuring the stability and positioning accuracy of the light guide 30 within the carrier cavity 21. This design avoids optical path deviations caused by installation errors, ensuring high efficiency in optical signal transmission and clarity of status indication.

[0063] In this embodiment, the carrier plate 25 has a mounting opening communicating with the carrier cavity 21, and at least one of the hard disk and the light guide 30 is mounted in the carrier cavity 21 through the mounting opening.

[0064] In this embodiment, the hard disk assembly 2 further includes a locking member 50, which is connected to the carrier member 20 and is positionally adjustable on the carrier member 20. The locking member 50 has a locked position and a released position that avoids the hard disk. When the locking member 50 is in the locked position, at least a portion of the locking member 50 abuts against the hard disk to limit the hard disk between at least a portion of the locking member 50 and the carrier member 20. The locking member 50 is a screw.

[0065] In the above embodiments, the use of the locking member 50 ensures the hard drive is securely fixed to the carrier 20. Especially when the device is subjected to vibration or movement, the hard drive will not loosen or fall off due to external forces, effectively preventing data loss or hardware damage and improving the overall security and reliability of the system. The adjustable position of the locking member 50 allows the hard drive to be fixed in different positions, especially in less stable locations, where it can provide enhanced fixation. Users can easily unlock or lock the hard drive by simply operating the locking member 50, greatly reducing the complex steps and time required by traditional fixing methods and improving maintenance and upgrade efficiency.

[0066] Furthermore, the carrier 20 includes a carrier plate 25 and at least two mounting portions 250 disposed on the carrier plate 25. The at least two mounting portions 250 are spaced apart along the extending direction of the carrier 20, and the locking member 50 is detachably connected to the mounting portions 250. Thus, by providing at least two spaced mounting portions 250 on the carrier plate 25, the locking member 50 can be adjusted in position among the different mounting portions 250 as needed, thereby accommodating hard drives of different sizes or with different installation requirements. This flexible positioning method ensures that the device is compatible with multiple hard drive specifications, enhancing the system's adaptability and versatility. Moreover, the detachable connection between the locking member 50 and the mounting portions 250 allows users to quickly install or remove the locking member 50 without tools. This design not only reduces installation time but also lowers the risk of hardware damage due to improper installation or removal, facilitating hard drive maintenance and upgrades.

[0067] Specifically, the mounting part 250 is provided with a mounting hole and an internal thread on the wall of the mounting hole. The locking member 50 includes a locking rod and an abutment block. The locking rod is provided with an external thread that matches the internal thread. The abutment block is located at the end of the locking rod. The outer edge of the abutment block protrudes from the outer edge of the locking rod. The abutment block is used to abut against the hard disk.

[0068] The aforementioned configuration, with the locking element 50 and mounting part 250 connected by threads, provides precise positioning and secure fixation, preventing displacement of the hard drive due to vibration during use, ensuring the security and stability of data reading and writing, and also preventing wear on the hard drive interface, thus extending the hard drive's lifespan. Furthermore, the threaded connection between the locking lever and mounting part 250 allows the position of the locking element 50 to be adjusted within a certain range. This flexibility allows the design to adapt to hard drives of different thicknesses or sizes, enhancing hardware compatibility and meeting the needs of various application scenarios. The threaded connection design makes the installation and removal of the locking element 50 convenient and quick, requiring no additional tools; simply rotating the locking lever is sufficient to lock or loosen it. This significantly saves time and labor costs for hardware maintenance and upgrades, improving operational efficiency.

[0069] In this embodiment, the guide member 11 is provided with a limiting groove 110 communicating with the guide groove 12; the carrier member 20 further includes: a carrier plate 25, on which a hard disk and a light guide member 30 are provided; a snap-fit ​​plate 27, which is positionably disposed on the carrier plate 25, and is provided with a snap hook 270. The snap-fit ​​plate 27 has a snap-fit ​​position and a clearance position; when the snap-fit ​​plate 27 is in the snap-fit ​​position, the snap hook 270 is snapped into the limiting groove 110; when the snap-fit ​​plate 27 is in the clearance position, the snap hook 270 is clearance-avoiding the limiting groove 110.

[0070] In the above embodiment, the combined use of the limiting groove 110 and the hook 270 enables the hard drive to be quickly and accurately positioned in a preset position. When the locking plate 27 is in the locking position, the hook 270 automatically engages with the limiting groove 110 of the guide member 11, forming a firm physical connection and ensuring the stable fixation of the hard drive on the carrier plate 25, reducing installation time and improving work efficiency. When the locking plate 27 is in the clearance position, the hook 270 can be directly removed from the limiting groove 110 of the guide member 11, thereby enabling the disassembly of the hard drive for easy replacement. This not only ensures the stable fixation of the hard drive inside the carrier member 20 but also effectively prevents hard drive displacement or damage caused by equipment vibration or accidental impact. The hard drive positioning and fixation can be completed without tools, greatly simplifying the user's operation process and reducing operational difficulty.

[0071] Specifically, the carrier 20 also includes a limiting plate 28, which is disposed on the carrier plate 25. The limiting plate 28 is disposed opposite to the snap-fit ​​plate 27, and is located on the side of the snap-fit ​​plate 27 away from the snap hook 270, so as to limit and abut against the snap-fit ​​plate 27. In this way, when the snap-fit ​​plate 27 switches from the snap-fit ​​position to the avoidance position, the snap-fit ​​plate 27 abuts against the limiting plate 28, at which time the snap hook 270 on the snap-fit ​​plate 27 can be completely removed from the limiting groove 110.

[0072] In this embodiment, the carrier plate 25 is provided with a latching groove 252, which is located on the side of the latching plate 27 away from the latch hook 270. This provides the user with a more convenient means to trigger the position switching of the latching plate 27. After the user presses the latching plate 27 to the avoidance position with one finger, the latch hook 270 on the latching plate 27 can be removed from the limiting groove 110. By inserting another finger into the latching groove 252, the carrier 20 can be moved, thus separating the carrier 20 from the hard drive and releasing the hard drive from its locked state. Therefore, the user only needs to use their finger or a suitable tool to hold the groove and push the latching plate 27 to the avoidance position, making hard drive removal simple and easy without the need for complicated tools.

[0073] Optionally, the snap-fit ​​plate 27 is a flexible plate.

[0074] In this embodiment, support ribs 13 are respectively provided on the two side walls of the guide member 11 in the guide groove 12. The support ribs 13 extend along the extension direction of the carrier member 20. Support grooves 251 are respectively provided on the two side walls of the carrier member 20 along its extension direction. The support ribs 13 are connected to the support grooves 251 to support the carrier member 20.

[0075] In this way, the cooperation between the support rib 13 and the support groove 251 forms a double structural support, effectively enhancing the stability and load-bearing capacity of the carrier 20. It also makes the installation and removal of the carrier 20 simpler and faster. Users only need to align the support groove 251 of the carrier 20 with the support rib 13 in the guide groove 12 to easily complete the fixation, without the need for additional fixing tools, thus improving operational efficiency. This design ensures that the carrier 20 can maintain its geometry and position when subjected to external pressure or vibration, thereby protecting the hard drive from damage and improving data storage security. It not only increases structural strength but also provides additional airflow space for the hard drive assembly 2.

[0076] Optionally, there are at least two guide slots 12. Users can flexibly select and configure the number of hard drives according to business needs, thereby improving the scalability of data storage and processing.

[0077] In this embodiment, the guide member 11 is also provided with multiple heat dissipation holes. This helps to accelerate the circulation of hot air around the hard drive, reduce the operating temperature of the hard drive, optimize overall heat dissipation performance, and extend the service life of the hard drive.

[0078] In this embodiment, the hard drive has an M.2 interface, and the adapter card 40 has a hard drive interface facing the hard drive. The M.2 interface is used to connect with the hard drive interface. Thus, the M.2 interface supports a fixed type of SSD, including hard drives of different lengths and widths. The adapter card design can adapt to corresponding M.2 interface hard drives, enhancing the system's hardware compatibility and flexibility, allowing users to replace or upgrade hard drives according to their actual needs.

[0079] This application also provides a server including the aforementioned PCIe device. The fast-swap feature of the PCIe device allows server administrators to quickly replace or upgrade hard drives without complex disassembly and assembly processes, significantly reducing the time and manpower costs required for hardware maintenance and upgrades, and improving server availability and management efficiency. Furthermore, the half-height, half-length PCIe device design is particularly suitable for space-constrained server environments. By optimizing the internal layout, the server can accommodate more storage devices within a limited space, thereby increasing server density and space utilization.

[0080] The foregoing has provided a detailed description of a PCIe device and server provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
