Description

Technical Field

[0001] This invention relates to the field of server architecture technology, and more specifically, to a server chassis and a server. Background Technology

[0002] With the rapid development of server technology, the demand for servers is increasing day by day. In order to reduce costs and improve operational efficiency, data centers need to deploy more servers within the available space, which puts forward higher requirements for the efficient utilization of the internal space of servers.

[0003] In related technologies, servers are equipped with GPU (Graphics Processing Unit) modules. When there is no need for GPU configuration but other configuration requirements, a different chassis is needed to meet the corresponding requirements. In other words, the server configuration is limited, which increases the development and manufacturing costs of the chassis.

[0004] Therefore, how to solve the technical problem of limited server configuration in related technologies is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application provides a server chassis and a server to at least solve the problem of limited server configuration in related technologies.

[0006] This application provides a server chassis, including:

[0007] The enclosure has a rear window area, which includes a first mounting space for installing a first electronic module or a second electronic module.

[0008] The housing has mounting limit holes and fixing holes on its two side walls along its width direction. The mounting limit holes are used to cooperate with the mounting limit components of the second electronic module for limiting, and the fixing holes are used to cooperate with the locking components of the second electronic module for locking.

[0009] This application also provides a server, including the aforementioned server chassis and a second electronic module, wherein the second electronic module is provided with an installation limiting member and a locking member.

[0010] Through this application, since the enclosure has mounting limiting holes and fixing holes on its two side walls along its width direction, when installing the second electronic module, the mounting limiting holes can be used in conjunction with the mounting limiting components of the second electronic module to limit its installation, and the fixing holes can be used in conjunction with the locking components of the second electronic module to lock it in place. This allows the second electronic module to be installed in the first installation space. At the same time, the first installation space can originally be used to install the first electronic module. Therefore, the first and second electronic modules can be flexibly switched and installed within the first installation space, achieving compatibility between the first and second electronic modules. In other words, a single server enclosure can be used to meet multiple configuration requirements, allowing users to select electronic modules according to their actual needs. For example, when the server does not require a computing device module, a hard drive module or a first expansion card module can be used to utilize the first installation space, avoiding the first installation space being idle and occupying space when no computing device module is needed, and also eliminating the need to use another server enclosure to meet hard drive or expansion requirements. As can be seen, this server chassis allows for flexible configuration of the first installation space in the rear window area, enabling different electronic modules to be installed there. This diversification of module installation in the first installation space allows servers using this chassis to better meet the diverse performance requirements of different business scenarios. It is evident that this solution achieves extreme optimization in the utilization of the first installation space in the rear window area, maximizing its use. This facilitates increased hardware density within the limited server chassis space, enhances the overall performance of the server chassis, and consequently saves data center space, reduces operating costs, and fundamentally solves the current problem of needing to switch chassis when reconfiguring servers. It also reduces server reconfiguration costs and shortens reconfiguration time, bringing significant convenience to server reconfiguration.

[0011] Therefore, it can solve the problem of limited server configuration, achieve diversified server configuration, and reduce the development and manufacturing costs of server racks. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0043] It should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "installed," "connected," and "linked" should be interpreted broadly, for example, they can be fixed connections, detachable connections, or integral connections; they can be mechanical connections or electrical connections; they can be direct connections or indirect connections through an intermediate medium; they can be internal connections between two elements. The terms "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, wherein the acceptable deviation range is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where an acceptable deviation range for approximate parallelism can be, for example, within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where an acceptable deviation range for approximate perpendicularity can also be, for example, within 5°. "Equal" includes absolute equality and approximate equality, where an acceptable deviation range for approximate equality can be, for example, a difference between the two equal items being less than or equal to 5% of either one. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] 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.

[0045] It should be noted that, in this embodiment of the invention, the first direction refers to the length direction (or depth direction or front-to-back direction) of the server enclosure 1, the second direction refers to the width direction of the enclosure 1, and the third direction refers to the height direction of the enclosure 1. The first direction, the second direction, and the third direction are perpendicular to each other. For ease of understanding, as follows... Figure 1 As shown, the first direction refers to Figure 1 The Y-axis direction, the second direction refers to Figure 1 In the X-axis direction, the third direction refers to Figure 1 The Z-axis direction in the equation.

[0046] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This invention provides a server chassis, including a chassis 1. The chassis 1 has a rear window area, which includes a first mounting space for mounting a first electronic module or a second electronic module. Figure 5 As shown, the box body 1 has a first limiting hole 11 and a fixing hole 12 on its two side walls along its width direction. The first limiting hole 11 is used to cooperate with the installation limiting member 41 of the second electronic module for limiting, and the fixing hole 12 is used to cooperate with the locking member 42 of the second electronic module for locking.

[0047] In other words, in this application, a first limiting hole 11 and a fixing hole 12 are respectively provided on the two side walls of the housing 1 along its width direction. When installing the second electronic module, the first limiting hole 11 can be used to cooperate with the installation limiting member 41 of the second electronic module to limit the installation of the second electronic module, and the fixing hole 12 can be used to cooperate with the locking member 42 of the second electronic module to lock it, thus fixing the second electronic module. This allows the second electronic module to be installed in the first installation space. At the same time, the first installation space can originally be used for the installation of the first electronic module. Therefore, the installation of the first electronic module can be realized. The flexible switching between the first and second electronic modules within the first installation space ensures compatibility between them. This means a single server chassis can meet various configuration requirements, allowing users to select electronic modules based on their specific needs. For example, when the server does not require computing module 3, hard drive module 4 or the first expansion card module 5 can be used to utilize the first installation space. This avoids the first installation space being idle when computing module 3 is not needed, and also eliminates the need for a separate server chassis when hard drive or expansion requirements arise. Therefore, this server chassis allows for flexible configuration of the first installation space in the rear window area, enabling different electronic modules to be installed within this space. This diversification of module installation in the first installation space in the rear window area allows servers using this chassis to better meet the diverse performance requirements of different business scenarios. As can be seen, this solution optimizes the utilization of the primary installation space in the rear window area, maximizing its use. This allows for increased hardware density within the limited server chassis space, enhancing the overall performance of the server chassis. Consequently, it saves data center space, reduces operating costs, and fundamentally solves the current problem of needing to switch chassis when reconfiguring servers. This reduces server reconfiguration costs and shortens reconfiguration time, greatly simplifying server reconfiguration. Therefore, it can solve the problem of limited server configuration, achieving diversified server configurations and reducing chassis development and manufacturing costs.

[0048] It should be noted that the rear window area of ​​the enclosure 1 refers to the area inside the enclosure 1 near the rear window 2; the first installation space is the area at a certain height inside the rear window 2 between one inner wall in the width direction of the enclosure 1 and the other inner wall in the width direction of the enclosure 1. For example, the first installation space occupies 1U (1 Unit = 1.75 inches = 4.445 cm) of height space. For example, the server enclosure can be a 2U server enclosure, and the first installation space can be the upper 1U space of the rear window area of ​​the 2U server enclosure.

[0049] Additionally, it should be noted that the first electronic module can be a computing device module 3, which can be a GPU (Graphics Processing Unit) module. For example, the computing device module 3 includes four GPUs with a width of 3 / 4 of their length. The installation of the first electronic module can adopt a structure found in related technologies, that is, the housing 1 is provided with a support member, and when the computing device module 3 is installed in the first installation space, it is fixed to the support member, thereby realizing the installation and fixation of the computing device module 3 in the first installation space. Further details will not be elaborated here.

[0050] Furthermore, this embodiment does not specifically limit the second electronic module. For example, the second electronic module can be a hard disk module 4 or a first expansion card module 5, or other electronic device components. Those skilled in the art can configure different second electronic modules according to actual needs, as long as the second electronic module is provided with an installation limiting member 41 and a locking member 42 to correspondingly engage and limit the second electronic module with the first limiting hole 11 and fixing hole 12 provided on the housing 1, thus enabling the installation of the second electronic module within the first installation space. Exemplarily, the second electronic module includes a module base, and both side walls of the module base are provided with installation limiting members 41 and locking members 42. For example, such as... Figure 4 As shown, in some embodiments, the hard disk module 4 includes a first base 44, such as Figure 11 As shown, the first expansion card module 5 includes a second base 51. The outer side of the first base 44 and the outer side of the second base 51 are provided with a mounting limit member 41 and a locking member 42.

[0051] Additionally, it should be noted that when the second electronic module is a hard disk module 4, the hard disk module 4 can be a 3.5-inch hard disk or a 2.5-inch hard disk. For example, the hard disk module 4 includes four 3.5-inch hard disks. Furthermore, this embodiment does not limit the specific type and structure of the first expansion card module 5. For example, the first expansion card module 5 is a 3PCIe-4SSD-M.2 module, that is, the first expansion card module 5 includes three PCIe (Peripheral Component Interconnect Express) cards, four solid-state drives, and an M.2 interface.

[0052] In addition, to facilitate the setting of fixing holes 12, such as Figure 5 As shown, in some embodiments, the inner sidewall of the housing 1 is provided with a bending member 13. The bending member 13 includes a limiting plate and a fixing plate connected together. There is a gap between the limiting plate and the inner sidewall of the housing 1. The fixing plate is fixed to the inner sidewall of the housing 1. The fixing hole 12 is provided in the limiting plate.

[0053] In other words, this embodiment adds a bending member 13 to the inner side wall of the box body 1 and forms a fixing hole 12 on the bending member 13, avoiding the need to open a fixing hole 12 on the box body 1. This helps to ensure the integrity of the side wall of the box body 1 and avoids damaging the overall integrity of the side wall of the box body 1. At the same time, it helps to increase the structural strength of the side wall of the box body 1. In addition, this solution also facilitates the processing of the fixing hole 12. Additionally, it is understood that there is a gap between the limiting plate and the inner wall of the housing 1, and the fixing hole 12 is located in the limiting plate, that is, the fixing hole 12 penetrates the thickness of the limiting plate. When the locking member 42 (e.g., the locking pin 421 below) extends into the fixing hole 12, one end of the locking member 42 (e.g., the locking pin 421) can protrude from the fixing hole 12 and be located in the gap between the limiting plate and the inner wall of the housing 1. This scheme can ensure that the locking member 42 (e.g., the locking pin 421) and the fixing hole 12 have sufficient mating length, thereby ensuring the effectiveness of the mating between the locking member 42 (e.g., the locking pin 421) and the fixing hole 12. It should be noted that the specific structure of the bending member 13 is not limited in this embodiment, as long as it can be ensured that the bending member 13 can be fixed to the inner wall of the housing 1, and there is a gap between the limiting plate and the inner wall of the housing 1. For example, the limiting plate is arranged parallel to the inner wall of the housing 1. Both ends of the limiting plate are connected to fixing plates via bending portions 4331. There are two fixing plates, each connected to one end of the limiting plate via a bending connection portion. The limiting plate, bending portions 4331, and fixing plates form a U-shaped structure. It is understood that the bending connection portions are perpendicular to the limiting plate and the fixing plates, respectively, and the length of the bending connection portion determines the size of the gap between the limiting plate and the inner wall of the housing 1.

[0054] It should be noted that the presence of the bending component 13 does not affect the installation of the first electronic module. That is, the bending component 13 can be a modified structural component reserved for the server chassis, and it does not interfere with the installation of the first electronic module.

[0055] Furthermore, please combine Figure 1 , Figure 16 , Figure 26 and Figure 27In some embodiments, the rear window area of ​​the server chassis further includes a second mounting space for installing a third electronic module 6 or a fourth electronic module 7; the chassis 1 has a rear window 2 at one end of the rear window area, the rear window 2 includes two spaced second guide members 21 and a connecting plate 22 connected between the two second guide members 21, the two second guide members 21 and the connecting plate 22 form a U-shaped structure, and the U-shaped groove of the U-shaped structure corresponds to the second mounting space; the bottom edge of the second guide member 21 is provided with a beveled edge 23 and a reinforcing protrusion 24 between the bottom edge of the second guide member 21 and the connecting plate 22.

[0056] In other words, this embodiment improves the structure of the rear window 2, enabling flexible switching between the installation of the third electronic module 6 and the fourth electronic module 7 in the second mounting space. The rear window 2 has a U-shaped structure corresponding to the second mounting space, meaning that the structure of the rear window 2 is minimized at that location. This results in only the connecting plate 22 serving as a support structure along the width of the server chassis at the second mounting space, without defining a closed interface on the rear window 2. This allows sufficient space to accommodate either the third electronic module 6 or the fourth electronic module 7. Simultaneously, the structural strength of the rear window 2 is improved by incorporating the beveled edge 23 and the reinforcing protrusion 24.

[0057] As can be seen, this embodiment further enhances the diversity and flexibility of the server back window 2 configuration.

[0058] In addition to the server chassis described above, this embodiment of the invention also provides a server, which includes the server chassis disclosed in any of the above embodiments. The server also includes one of a first electronic module and a second electronic module. The second electronic module is provided with an installation limiting member 41 and a locking member 42.

[0059] In other words, the first electronic module and the second electronic module can be switched and installed in the first installation space. When the first electronic module needs to be configured, it is installed in the first installation space. When the first electronic module does not need to be configured, the second electronic module can be installed in the first installation space to meet the configuration requirements of the second electronic module. For example, the first installation space can be configured with computing device module 3, hard disk module 4, or first expansion card module 5. The first installation space supports seamless switching between these modules, ensuring compatibility. In other words, this server can use a single enclosure 1 to meet various configuration requirements, allowing users to select preset device modules as needed. For instance, when computing device module 3 is not required, hard disk module 4 or first expansion card module 5 can be used within the first installation space. This avoids the first installation space being idle when computing device module 3 is not needed, and also eliminates the need to use a different enclosure 1 (rear window 2) to meet hard disk or expansion requirements. Therefore, this server allows for flexible configuration of the first installation space in the rear window area, enabling different preset device modules to be used. This diversifies module installation within the first installation space and allows the server to better meet the diverse performance requirements of different business scenarios. As can be seen, this solution has optimized the utilization of the first installation space in the rear window area to the extreme, achieving maximum utilization of the first installation space. This is conducive to increasing the density of hardware configuration within the limited server space, enhancing the overall performance of the server, and thus saving data center space and reducing operating costs. It fundamentally solves the current problem of needing to switch chassis 1 when reconfiguring servers, reduces server reconfiguration costs, shortens reconfiguration time, and brings great convenience to server reconfiguration.

[0060] Additionally, please refer to Figure 4 and Figure 5 It is understandable that when installing the second electronic module, for example, when installing the hard disk module 4 or the first expansion card module 5, the installation limiting member 41 of the hard disk module 4 or the first expansion card module 5 is aligned and inserted with the first limiting holes 11 on both sides of the housing 1 to achieve the positioning of the hard disk module 4 or the first expansion card module 5. When the hard disk module 4 or the first expansion card module 5 is installed in place, the locking member 42 cooperates with the fixing hole 12 to achieve the fixing of the hard disk module 4 or the first expansion card module 5 to the housing 1, that is, to achieve the installation and fixing of the hard disk module 4 or the first expansion card module 5 in the first installation space.

[0061] In other words, this embodiment, while maintaining the same installation structure as related technologies for the computing device module 3, further provides first limiting holes 11 and fixing holes 12 on both side walls along the width direction of the enclosure 1, and correspondingly provides installation limiting components 41 and locking components 42 on the hard disk module 4 and the first expansion card module 5, respectively. By utilizing the cooperation between the installation limiting component 41 and the first limiting hole 11, and the cooperation between the locking component 42 and the fixing hole 12, the switching installation and fixing of the hard disk module 4 and the first expansion card module 5 within the first installation space can be achieved. That is, when switching the installation of the hard disk module 4 and the first expansion card module 5, only the first limiting holes 11 and fixing holes 12 need to be opened on the enclosure 1, simplifying the modification structure of the enclosure 1.

[0062] In addition, it should be noted that this embodiment does not limit the specific structure of the first limiting hole 11 and the mounting limiting member 41, as long as the two can cooperate to limit the hard disk module 4 or the first expansion card module 5.

[0063] like Figure 5 As shown, in some embodiments, the first limiting hole 11 is a hole with a top opening and a corner; the mounting limiting member 41 includes a mating post and a limiting stop, the mating post is used to slide with the first limiting hole 11, and the limiting stop is located at the free end of the mating post and protrudes radially from the mating post.

[0064] When installing the hard disk module 4 or the first expansion card module 5, the mating post of the installation limiting member 41 is inserted into the first limiting hole 11 from the top opening of the first limiting hole 11, and the mating post slides along the first limiting hole 11. The mating post slides past the corner of the first limiting hole 11 and finally achieves mating and limiting with the first limiting hole 11. Since the limiting stop protrudes radially from the mating post, the radial dimension of the limiting stop is greater than the radial dimension of the first limiting hole 11, so that the limiting stop cannot pass through the first limiting hole 11, that is, it can prevent the mating post from coming out of the first limiting hole 11.

[0065] It should be noted that the specific shape of the first limiting hole 11 is not limited in this embodiment. For example, the first limiting hole 11 can be an L-shaped hole or an I-shaped hole, as long as the top of the first limiting hole 11 is open to allow the mounting limiting member 41 to enter the first limiting hole 11, and the first limiting hole 11 has a corner to ensure the reliability of the fit between the mounting limiting member 41 and the first limiting hole 11, and to prevent the mounting limiting member 41 from coming out of the first limiting hole 11. Correspondingly, the mounting limiting member 41 can be an I-shaped pin or an L-shaped structure with a bent structure at the free end of the mating post, etc.

[0066] In addition, the above embodiments do not limit the specific structure of the locking member 42, as long as the locking member 42 can be connected with the fixing hole 12.

[0067] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the locking member 42 includes a locking post 421, a locking sleeve 422, and a locking cap 423. The locking post 421 is used to engage with the fixing hole 12 for fixation. The locking sleeve 422 is installed on the hard disk module 4 or the first expansion card module 5, and the locking post 421 is movably disposed inside the locking sleeve 422. The locking cap 423 is connected to the locking post 421 and is sleeved on the outside of the locking sleeve 422. When the locking cap 423 and the locking sleeve 422 have a preset axial relative position, the locking cap 423 can rotate circumferentially relative to the locking sleeve 422. When the two have a preset circumferential relative orientation, the locking cap 423 can move axially relative to the locking sleeve 422. When the locking cap 423 moves axially relative to the locking sleeve 422, it can drive the locking post 421 to extend into the fixing hole 12 or retract from the fixing hole 12.

[0068] It is understood that the locking cap 423 is connected to the locking pin 421. Therefore, when the locking cap 423 moves axially relative to the locking sleeve 422, it can drive the locking pin 421 to move axially relative to the locking sleeve 422. This allows the locking pin 421 to extend out of one end of the locking sleeve 422 or retract into the locking sleeve 422. When the locking pin 421 extends out of one end of the locking sleeve 422, it can extend into the fixing hole 12 and cooperate with the fixing hole 12 for limiting. Combined with the cooperation of the installation limiting member 41 and the first limiting hole 11, the hard disk module 4 or the first expansion card module 5 is fixed relative to the enclosure 1. When the locking pin 421 retracts into the locking sleeve 422, it exits the fixing hole 12, thereby unlocking the hard disk module 4 or the first expansion card module 5 from the enclosure 1. At this time, the hard disk module 4 or the first expansion card module 5 can be disassembled. Additionally, it should be noted that the locking cap 423 can only move axially relative to the locking sleeve 422 when the locking cap 423 and the locking sleeve 422 have a preset circumferential relative orientation, so that the locking cap 423 can drive the locking pin 421 to extend or retract. When the circumferential relative position between the locking cap 423 and the locking sleeve 422 is not a preset circumferential relative orientation, the locking cap 423 cannot move axially, thus locking the axial position of the locking cap 423 and the locking pin 421, maintaining the position of the locking pin 421 engaged with the fixing hole 12, and ensuring that the locking pin 421 and the fixing hole 12 are properly engaged. The reliability of the locking mechanism is ensured. When it is necessary to disassemble the hard drive module 4 or the first expansion card module 5, by pulling the locking cap 423 axially out to a preset position, the locking cap 423 and the locking sleeve 422 are in a preset axial relative position. This allows the locking cap 423 to rotate circumferentially relative to the locking sleeve 422, so that the locking cap 423 and the locking sleeve 422 are not in the preset circumferential relative position, making it impossible for the locking cap 423 to move axially. This ensures that the locking post 421 cannot extend when the hard drive module 4 or the first expansion card module 5 is disassembled, thereby ensuring that the hard drive module 4 or the first expansion card module 5 can be smoothly disassembled from the housing 1.

[0069] Furthermore, to ensure that the locking cap 423 can move axially relative to the locking sleeve 422 when the locking cap 423 and the locking sleeve 422 have a preset circumferential relative orientation, in some embodiments, the outer periphery of the locking sleeve 422 is provided with a first flat surface 4221, and the inner periphery of the locking cap 423 is provided with a second flat surface. When the second flat surface and the first flat surface 4221 are located in the same circumferential orientation, that is, when the second flat surface corresponds to the first flat surface 4221, the locking cap 423 can move axially relative to the locking sleeve 422 to drive the locking pin 421 to extend or retract. It should be noted that this embodiment does not limit the specific number and distribution of the first flat surface 4221 and the second flat surface, as long as the first flat surface 4221 and the second flat surface cooperate, it can limit the locking cap 423 and the locking sleeve 422 to only be able to move axially and not rotate circumferentially. For example, the outer periphery of the locking sleeve 422 is provided with two first flat surfaces 4221, and the two first flat surfaces 4221 are arranged at 180°; correspondingly, there are two second flat surfaces, and the two second flat surfaces are arranged at 180°.

[0070] Furthermore, in order to enable the locking cap 423 to rotate relative to the locking sleeve 422, in some embodiments, the locking sleeve 422 includes a first bushing portion and a second bushing portion. The outer diameter of the first bushing portion is larger than the outer diameter of the second bushing portion, so that the first bushing portion and the second bushing portion form a stepped structure. The first flat surface 4221 is provided on the outer periphery of the first bushing portion. When the locking cap 423 moves axially to the second bushing portion, the locking cap 423 can rotate circumferentially relative to the second bushing portion. When the locking cap 423 rotates circumferentially, the second flat surface and the first flat surface 4221 are circumferentially misaligned. At this time, the end of the protrusion structure where the second flat surface is located is axially limited with the end face of the first bushing portion, so that the locking cap 423 cannot move axially. When the locking cap 423 rotates to the position where the second flat surface and the first flat surface 4221 are circumferentially aligned, the locking cap 423 can move axially along the first bushing portion.

[0071] Furthermore, to ensure that the locking cap 423 can be quickly positioned to a position where it can move axially relative to the locking sleeve 422, in some embodiments, the outer periphery of the locking cap 423 is provided with a third flat surface 4231, and the side wall of the hard disk module 4 or the first expansion card module 5 used to fix the locking sleeve 422 is also provided with a mating hole for the locking cap 423 to be inserted. The inner periphery of the mating hole is provided with a fourth flat surface, that is, the mating hole is a hole with a fourth flat surface. When the locking cap 423 is rotated to the point where the third flat surface 4231 is aligned with the fourth flat surface, the second flat surface is aligned with the first flat surface 4221. At this time, the locking cap 423 can be inserted into the mating hole, and the locking cap 423 can move axially relative to the locking sleeve 422. When the locking cap 423 is pulled out from the mating hole, the locking cap 423 can rotate relative to the locking sleeve 422. In other words, this embodiment uses the alignment of the third flat surface 4231 with the fourth flat surface of the mating hole as a reference to determine the alignment of the second flat surface with the first flat surface 4221, thereby facilitating quick positioning of the alignment of the second flat surface with the first flat surface 4221.

[0072] In addition, such as Figure 9 As shown, in some embodiments, the second electronic module includes a hard disk module 4, which includes at least one hard disk tray 43. The hard disk tray 43 is used to switch between installing a first hard disk and a second hard disk. The size of the second hard disk is smaller than that of the first hard disk. The bottom of the hard disk tray 43 is provided with a locking hole 431 for locking the second hard disk.

[0073] It is understandable that the number of hard drive trays 43 determines the number of hard drives. The more hard drive trays 43 there are, the more hard drives the hard drive module 4 includes. For example, the hard drive module 4 includes four hard drive trays 43 arranged sequentially along the width direction of the housing 1, with one hard drive in each tray. Furthermore, in this embodiment, the hard drive trays 43 are used to switch between installing the first hard drive and the second hard drive. That is, the hard drive trays 43 can install both the first and second hard drives, enabling flexible switching between them. Additionally, since the second hard drive is smaller than the first hard drive, the size of the hard drive tray 43 matches the size of the first hard drive to ensure that both the first and second hard drives can be installed in the trays 43. Furthermore, this embodiment provides a locking hole 431 at the bottom of the hard drive tray 43. A locking member passes through the locking hole 431 to lock the second hard drive. That is, when switching to install the second hard drive, no additional adapter is needed; a locking member for fixing the second hard drive can be directly attached to the bottom of the hard drive tray 43. The locking member can be a screw. As can be seen, this solution allows for flexible switching between hard drives of different sizes. It supports not only the first hard drive but also the second hard drive. Furthermore, by pre-drilling a locking hole 431 at the bottom of the hard drive tray 43 for the second hard drive, the second hard drive can be directly secured using locking components. This design greatly simplifies the process of replacing hard drives of different sizes, improves the efficiency of hard drive replacement, and allows users to flexibly switch hard drive sizes according to actual storage needs. This provides great convenience for adjusting server storage configurations. Moreover, it eliminates the need for additional adapters, reducing compatibility issues and additional costs associated with using adapters. It should be noted that this embodiment does not limit the specific sizes of the first and second hard drives. For example, the first hard drive is a 3.5-inch hard drive, and the second hard drive is a 2.5-inch hard drive.

[0074] In addition, to ensure the structural strength and rigidity of the hard drive bracket 43, as well as to ensure the smooth installation of the hard drive bracket 43 and its shock absorption effect, such as Figure 9 and Figure 10 As shown, in some embodiments, the hard disk tray 43 includes a rigid base 432 and a flexible member 433. The rigid base 432 is provided with flexible members 433 on both outer side walls along the second direction. The rigid base 432 is provided with a second limiting hole 4321. The inner side of the flexible member 433 is provided with a bending portion 4331, which is used to slide with the second limiting hole 4321.

[0075] In other words, in this embodiment, the hard drive bracket 43 is formed by combining a rigid base 432 and a flexible component 433. The rigid base 432 has sufficient structural strength and rigidity to provide reliable support for the hard drive. The flexible component 433 has a certain degree of flexibility, can be deformed under pressure, and has a certain buffering effect, which is conducive to the smooth assembly of the hard drive bracket 43 to the first base 44 of the hard drive module 4, and has a certain shock absorption effect on the hard drive during use. In addition, to facilitate the assembly of the rigid base 432 and the flexible component 433, this embodiment utilizes the cooperation and positioning of the bent portion 4331 and the second limiting hole 4321 to achieve the correct assembly of the rigid base 432 and the flexible component 433, ensuring the correctness and reliability of the assembly of the rigid base 432 and the flexible component 433. That is, when assembling the rigid base 432 and the flexible component 433, the rigid base 432 is pushed between the two flexible components 433. It can be understood that one end of the two flexible components 433 is connected to an end member, and the other end of the two flexible components 433 is an open end, so that the rigid base 432 enters between the two flexible components 433 from the open end. When the second limiting hole 4321 slides to the position aligned with the bent portion 4331, the bent portion 4331 springs into the second limiting hole 4321, so that the second limiting hole 4321 slides along the bent portion 4331 until the rigid base 432 slides into place. Understandably, when the rigid base 432 slides into place, the eighth fastener locks and secures the rigid base 432 to the end components at one end of the two flexible components 433, thus connecting the rigid base 432, the flexible components 433, and the end components into a single hard drive tray 43. That is, this embodiment utilizes the guiding cooperation of the second limiting hole 4321 and the bending portion 4331 to limit the installation between the rigid base 432 and the flexible components 433, ensuring the smoothness, correctness, and reliability of the assembly of the rigid base 432 and the flexible components 433. It should be noted that this embodiment does not limit the specific materials of the rigid base 432 and the flexible components 433. For example, the rigid base 432 is a sheet metal part, and the flexible components 433 are plastic parts.

[0076] In addition, such as Figure 4 As shown, in some embodiments, the hard disk module 4 includes a first base 44 and an upper cover 45 covering the first base 44. A space for accommodating the hard disk is formed between the upper cover 45 and the first base 44. The top of the upper cover 45 is provided with a first heat dissipation hole 451, and the portion of the upper cover 45 facing the rear window 2 is provided with a second heat dissipation hole 452.

[0077] In other words, this embodiment achieves efficient heat dissipation for the entire hard drive module 4 by maximizing the arrangement of heat dissipation holes on the upper cover 45 of the hard drive module 4. It should be noted that this embodiment does not limit the specific shape, number, or distribution of the first heat dissipation hole 451 and the second heat dissipation hole 452, as long as they effectively dissipate heat from the hard drive module 4. For example, both the first heat dissipation hole 451 and the second heat dissipation hole 452 are circular holes, and each is evenly distributed in the area corresponding to a single hard drive.

[0078] In addition, such as Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the second electronic module includes a first expansion card module 5. The first expansion card module 5 includes a second base 51 and three expansion card assemblies 52 disposed on the second base 51 and a hybrid module. The hybrid module includes a solid-state drive module and an onboard through-hole interface module. The solid-state drive module can support up to four solid-state drives.

[0079] In other words, the server provided in this embodiment is compatible with three expansion card components 52, solid-state drive modules, and onboard through-hole interface modules. For example, the expansion card component 52 includes a PCIe card, and the solid-state drive module can support up to four solid-state drives. That is, the first expansion card module 5 includes four SSD modules, and the onboard through-hole interface module can be an M.2 module. It should be noted that the SSD backplane can be fixed and grounded using pressure plates. The four SSDs, along with their corresponding brackets and sheet metal slides, cooperate to achieve the sliding installation and positioning of the SSD modules with the second base 51. Specific settings for the SSD modules can be found in relevant technologies and will not be elaborated here. In addition, the M.2 module can support two M.2 cards simultaneously, with the M.2 cards located on the front and back of the M.2 Riser card respectively. The M.2 cards support 80mm and 110mm length specifications. The 110mm length M.2 card can be fixed by extending the second base 51 and adding a plastic extension. This embodiment does not limit the specific installation of the M.2 module; relevant technologies can be referenced, and details will not be repeated here. The key point of this embodiment is that the three expansion card components 52, the solid-state drive module, and the onboard through-hole interface module are integrated into a first expansion card module 5 via the second base 51. Furthermore, the three expansion card components 52 and the hybrid module are arranged sequentially along the width direction of the enclosure 1, that is, from one end of the width direction of the enclosure 1, the three expansion card components 52 are arranged in a row. The hybrid module formed by the solid-state drive module and the onboard through-hole interface module is close to one side wall of the enclosure 1. This is beneficial for the rational use of space and facilitates structural layout and installation.

[0080] In addition, such as Figure 15As shown, in some embodiments, the expansion card assembly 52 includes a first expansion card 521, a first expansion card bracket 522, and a snap-fit ​​bracket 523. The first expansion card bracket 522 is used to hold the first expansion card 521 and is fixed to the second base 51 by a third fastener. The snap-fit ​​bracket 523 is connected to the first expansion card bracket 522 and is used to snap the first expansion card 521 in place.

[0081] In other words, in this embodiment, after the first expansion card 521 is installed on the first expansion card bracket 522, the first expansion card 521 is secured by the snap-fit ​​bracket 523 to improve the reliability and stability of the first expansion card 521's fixation, ensuring the stability of the first expansion card 521 during transportation and preventing the first expansion card 521 from shaking during server transportation, thus ensuring the accuracy of the first expansion card 521's position. Furthermore, this embodiment uses a third fastener to lock and fix the first expansion card bracket 522 to the second base 51. That is, the expansion card assembly 52 is fixed to the second base 51 by the third fastener. Compared to related technologies, this embodiment does not use plastic clips to fix the expansion card assembly 52, reducing costs and the structural space occupied by the expansion card assembly 52. ​​This frees up space for the installation of the solid-state drive module and the onboard through-hole interface module, enabling the integration of three expansion card assemblies 52, the solid-state drive module, and the onboard through-hole interface module into a single first expansion card module 5 via the second base 51.

[0082] Furthermore, such as Figure 12 As shown, in some embodiments, the second base 51 is provided with a first guide member 511 and a guide post 512. The first guide member 511 is spaced apart along the second direction and is used to guide the expansion card assembly 52 for installation along a third direction, which is perpendicular to the first direction and the second direction respectively. The guide post 512 and the first guide member 511 are respectively provided at both ends of the second base 51 along the first direction. The expansion card assembly 52 is provided with a first guide portion that slides with the first guide member 511 and a guide hole that cooperates with the guide post 512.

[0083] In other words, this embodiment guides the installation of the expansion card assembly 52 by setting the first guide member 511 and the guide post 512, so that the expansion card assembly 52 is inserted into the second base 51 in a third direction, ensuring the smooth installation and correct positioning of the expansion card assembly 52. ​​It should be noted that this embodiment does not limit the specific structure of the first guide member 511. Exemplarily, the first guide member 511 forms a first guide groove, and the expansion card assembly 52 has a first guide portion, which can be a guide piece. The guide piece is inserted into the first guide groove and slides along the first guide groove, so that the sliding cooperation between the first guide groove and the guide piece limits the installation of the expansion card assembly 52. ​​In some embodiments, the first guide member 511 is a sheet metal sheet, that is, the limiting structure for installing the expansion card assembly 52 is formed by bending or welding the sheet metal sheet. Additionally, exemplaryly, the second base 51 is entirely made of sheet metal. Furthermore, at the end of the second base 51 away from the first guide member 511, the other end of the expansion card assembly 52 is limited by the guide post 512.

[0084] Additionally, it should be noted that after the expansion card assembly 52 is installed in the third direction, the ninth fastener 5221 can be used to fix the expansion card assembly 52 to the second base 51. For example, the second base 51 is provided with a second fixing part 515 near the guide post 512, and the expansion card assembly 52 (e.g., the first expansion card bracket 522) is provided with a ninth fastener 5221. The ninth fastener 5221 is fixed with the second fixing part 515 to lock the expansion card assembly 52 to the second base 51.

[0085] In addition, such as Figure 12 As shown, in some embodiments, the second base 51 is provided with an analog video interface 513 and a universal serial bus interface 514. The side of the second base 51 is provided with a cable management bend for storing and organizing the cables of the analog video interface 513 and the universal serial bus interface 514. For example, the analog video interface 513 is a VGA interface; the universal serial bus interface 514 is a USB interface.

[0086] In other words, the second base 51 in this embodiment can support analog video interface 513 and universal serial bus interface 514, realizing resource compatibility between analog video devices and universal serial bus devices; at the same time, the cable management bending edge on the side of the second base 51 is used to store cables, which is beneficial for later maintenance and repair, improves maintenance efficiency, and makes the internal structure of the server more orderly and standardized, thus improving the overall aesthetics of the first expansion card module 5.

[0087] Additionally, to make the configuration of the rear window 2 more flexible, please combine... Figure 1 and Figure 16As shown, in some embodiments, the rear window area of ​​the server chassis further includes a second mounting space for installing a third electronic module 6 or a fourth electronic module 7; the server also includes a third electronic module 6 or a fourth electronic module 7, the third electronic module 6 including a network interface card module 61 and a second expansion card module 62 stacked along the height direction of the server chassis, and the fourth electronic module 7 including a third expansion card module; the rear window 2 of the server chassis includes a second guide 21 for guiding the installation of the third electronic module or the fourth electronic module. Exemplarily, the second mounting space is located below the first mounting space and is close to one side wall of the chassis 1 along the second direction.

[0088] In other words, in this embodiment, the second installation space of the rear window 2 can be used to house either the third electronic module 6 or the fourth electronic module 7. The second installation space can support arbitrary switching between the third electronic module 6 and the fourth electronic module 7, achieving compatibility between them. The third electronic module 6 includes a network interface card module 61 and a second expansion card module 62, and the fourth electronic module 7 includes a third expansion card module. That is, the server in this embodiment can effectively achieve compatibility between the network interface card and the expansion card. In related technologies, a network interface card installation slot is usually reserved. When there is no need to configure a network interface card, the reserved slot still occupies space in the enclosure 1, which cannot achieve flexible application of this space. This also limits the number of expansion cards and prevents the server from meeting the needs of more expansion cards. The solution in this embodiment solves this technical problem well. In other words, when a network interface card is required, the third electronic module 6 can be installed in the second installation space. Since the third electronic module 6 includes a network interface card module 61 and a second expansion card module 62 stacked along a third direction, it can meet the network interface card configuration requirements and provide the second expansion card module 62 to meet expansion card requirements. When no network interface card configuration is required, the fourth electronic module 7 can be installed in the second installation space. The fourth electronic module 7 includes the third expansion card module, which can meet higher expansion card requirements. Therefore, this server allows for flexible configuration of the second installation space in the rear window area, enabling diverse module installations and allowing the server to better meet the diverse performance requirements of different business scenarios. As can be seen, this solution has optimized the utilization of the second installation space in the rear window area to the extreme, achieving maximum utilization of the second installation space. This is conducive to increasing the density of hardware configuration within the limited server space, enhancing the overall performance of the server, and thus saving data center space and reducing operating costs. It fundamentally solves the current problem of needing to switch chassis 1 when reconfiguring servers, reduces server reconfiguration costs, shortens reconfiguration time, and brings great convenience to server reconfiguration.

[0089] Furthermore, such as Figure 21 and Figure 22 As shown, in some embodiments, the third expansion card module includes two independent third expansion cards 71 ​​stacked along the height direction, or the third expansion card module includes a fourth expansion card 72, the dimension of the fourth expansion card 72 along the height direction being equal to the dimension of the two third expansion cards 71 ​​along the height direction.

[0090] In other words, the third expansion card module in this embodiment can support two third expansion cards 71 ​​or one fourth expansion card 72. For example, the third expansion card 71 is a single-width PCIe card and the fourth expansion card 72 is a double-width PCIe card. That is, this embodiment can realize the switching between two single-width PCIe cards and one double-width PCIe card.

[0091] In addition, it is understandable that, such as Figure 21 and Figure 22 As shown, the third expansion card module also includes a third expansion card bracket 73, which is used to install a third expansion card 71 or a fourth expansion card 72. Furthermore, the third expansion card bracket 73 is provided with a rotating latch 732, which secures the third expansion card 71 or the fourth expansion card 72 when it is installed in place.

[0092] Furthermore, such as Figure 16 As shown, in some embodiments, the rear window area further includes a third mounting space and a fourth mounting space, both of which are located below the first mounting space. The second, third, and fourth mounting spaces are arranged sequentially along a second direction. The third mounting space includes a first sub-region and a second sub-region divided along the height direction. The first sub-region is used to install the input / output module 8, and the second sub-region is used to install the fourth expansion card module 9. The fourth mounting space is used to install the power module 10.

[0093] In other words, in this embodiment, the rear window 2 is also equipped with an input / output module 8, a fourth expansion card module 9 and a power module 10, and the input / output module 8 and the fourth expansion card module 9 are stacked vertically, which is conducive to making reasonable and full use of the third installation space. In addition, the second, third, and fourth installation spaces are all located below the first installation space, and are arranged sequentially from one side to the other along the second direction of the enclosure 1. That is, the second, third, and fourth installation spaces can occupy the same height space of the rear window 2. For example, the second, third, and fourth installation spaces occupy 1U of space, meaning that the server can be a 2U server. The upper 1U space of the rear window area is the first installation space, used to switch between the computing device module 3, the hard disk module 4, or the first expansion card module 5. The lower 1U space of the rear window area is divided into the second, third, and fourth installation spaces along the second direction. The second installation space is used to switch between the third electronic module 6 and the fourth electronic module 7. The third installation space is used to set up the input / output module 8 and the fourth expansion card module 9. The fourth installation space is used to set up the power supply module 10, thereby realizing the layout of the rear window 2.

[0094] Additionally, it is understood that when the third electronic module 6 is installed in the second installation space, the lower 1U space of the server can support one network interface card, two single-width PCIe cards, and input / output modules 8; when the fourth electronic module 7 is installed in the second installation space, the lower 1U space of the server can support three single-width PCIe cards and input / output modules 8, or one double-width PCIe card, one single-width PCIe card, and input / output modules 8.

[0095] In addition, such as Figure 18 , Figure 21 and Figure 22 As shown, in some embodiments, the first expansion card module 5, the second expansion card module 62, the third expansion card module, and the fourth expansion card module 9 all include an expansion card bracket and a rising card 74. The expansion card bracket is used to install expansion cards, and the side wall of the expansion card bracket is provided with a clearance hole. The rising card 74 is disposed on the outside of the side wall of the expansion card bracket corresponding to the clearance hole, and the rising card 74 is provided with a card slot for inserting expansion cards. The structure and size of the rising card 74 of the first expansion card module 5, the second expansion card module 62, the third expansion card module, and the fourth expansion card module 9 are all the same.

[0096] In other words, the ascender card 74 is interchangeable among the first expansion card module 5, the second expansion card module 62, the third expansion card module, and the fourth expansion card module 9. This reduces the development of additional boards, lowers the development and maintenance costs of the ascender card 74, and allows for flexible and arbitrary switching of the positions of the expansion cards in the first expansion card module 5, the second expansion card module 62, the third expansion card module, and the fourth expansion card module 9. This improves the convenience of expansion card installation and adjustment, further enhancing the flexibility and adaptability of server configuration. It should be noted that the ascender card 74 corresponds one-to-one with the expansion card; that is, each expansion card mounting position corresponds to one ascender card 74. Furthermore, it can be understood that the specific size and other dimensions of the expansion card brackets in the first expansion card module 5, the second expansion card module 62, the third expansion card module, and the fourth expansion card module 9 can be adaptively set according to the specific configuration of each expansion card module.

[0097] It should be noted that this embodiment does not limit the specific connection method between the riser card 74 and the expansion card bracket, as long as the connection between the riser card 74 and the expansion card bracket can be achieved.

[0098] like Figure 18 , Figure 21 and Figure 22 As shown, in some embodiments, the expansion card bracket is provided with a limiting fixing member 731, the rising card 74 is provided with a through hole passing through the limiting fixing member 731, and the rising card 74 is fixed to the expansion card bracket by a second fastener 741 connected to the limiting fixing member 731.

[0099] When installing the riser 74, align the through hole of the riser 74 with the limiting fastener 731 of the expansion card bracket and insert it. Once the riser 74 is in place, connect the second fastener 741 to the limiting fastener 731 to secure the riser 74 to the expansion card bracket. This solution allows for convenient installation and removal of the riser 74 and reliable positioning.

[0100] In addition, to facilitate the switching and installation of the third electronic module 6 and the fourth electronic module 7, such as Figure 17 As shown, in some embodiments, both the third electronic module 6 and the fourth electronic module 7 are provided with a first fixing part, which is fixed to the bottom of the housing 1 by a fourth fastener.

[0101] In other words, this embodiment guides the installation of the third electronic module 6 and the fourth electronic module 7 by setting the second guide member 21, ensuring that the third electronic module 6 or the fourth electronic module 7 is installed into the rear window 2 in a third direction, thus ensuring the smooth installation and correct positioning of the third electronic module 6 or the fourth electronic module 7. It should be noted that this embodiment does not limit the specific structure of the second guide member 21. Exemplarily, the second guide member 21 forms a second guide groove, and the third electronic module 6 and the fourth electronic module 7 are respectively provided with a second guide part. The second guide part can be a guide piece, which is inserted into the second guide groove and slides along the second guide groove. The sliding cooperation between the second guide groove and the second guide part limits the installation of the third electronic module 6 or the fourth electronic module 7. After the third electronic module 6 or the fourth electronic module 7 is installed in place, the first fixing part is fixed to the bottom of the housing 1 by using the fourth fastener, thereby fixing the third electronic module 6 or the fourth electronic module 7. For example, the fourth fastener is a hand-tight lock. That is, after the third electronic module 6 or the fourth electronic module 7 is installed in place, the third electronic module 6 or the fourth electronic module 7 can be fixed by manually tightening the fourth fastener. This solution enables tool-free installation and switching between the third electronic module 6 and the fourth electronic module 7, which is convenient for operation and facilitates server reconfiguration. For example, the bottom of the housing 1 is provided with a motherboard tray 14, and the motherboard tray 14 is provided with a first locking part 143. The fourth fastener is used to fix to the first locking part 143.

[0102] In addition, considering the specific implementation structure of the third electronic module 6, such as Figure 18 , Figure 19 and Figure 20 As shown, in some embodiments, the network interface card module 61 includes a network interface card and a third base 611. The third base 611 is provided with a first slide rail 6111 and a power supply device 6112. The network interface card is slidably connected to the first slide rail 6111. The second expansion card module 62 includes a second expansion card 621 and a second expansion card bracket 622. The second expansion card bracket 622 is connected to the third base 611.

[0103] During installation, the network interface card is slidably mounted onto the third base 611 along the first slide rail 6111, with the first slide rail 6111 pointing in the first direction. The power supply device 6112 supplies power to the network interface card. The second expansion card bracket 622 is connected to the third base 611, integrating the second expansion card module 62 and the network interface card module 61 into the third electronic module 6.
