Description

Technical Field

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

[0002] In related technologies, when installing the hard drive backplane of a server, the hard drive backplane is first installed onto the backplane bracket, and then the backplane bracket is fixed to the hard drive frame using flathead screws or captive screws.

[0003] However, this method of fixing the hard drive backplate increases the weight and cost of the entire machine on the one hand, and the screw connection between the backplate bracket and the hard drive frame makes operation and maintenance inconvenient on the other hand.

[0004] Therefore, how to reduce the weight and cost of the server and facilitate the installation of hard drive backplanes 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 that at least solves the problems of increased overall weight and cost due to backplane brackets and inconvenient hard drive backplane installation in related technologies.

[0006] This application provides a server, including:

[0007] The chassis is provided with at least two hard drive frame partitions, which are spaced apart along a first direction and extend along a second direction, the second direction being perpendicular to the first direction;

[0008] The hard drive backplate is inserted into one end of the hard drive frame partition along the second direction.

[0009] The latching device is located on the back panel of the hard drive and is latched to the chassis.

[0010] This application describes a method for installing a hard drive backplane. The backplane is aligned and inserted into the hard drive frame partition, ensuring a correct relative position. Once in place, the backplane is secured to the chassis via a snap-fit ​​mechanism. Because the backplane is directly mounted to one end of the hard drive frame partition (the rear end), the partition provides support, eliminating the need for a dedicated backplane bracket. This eliminates the need for a separate backplane bracket in related technologies, reducing the overall weight and cost of the server. In addition, the hard drive backplane is inserted into one end of the hard drive frame partition along the second direction. This insertion ensures that the hard drive backplane and the hard drive frame partition maintain the correct relative position and that the hard drive backplane is supported on the hard drive frame partition. Furthermore, the hard drive backplane is secured to the chassis via a snap-fit ​​device, ensuring the stability and reliability of the relative position between the hard drive backplane and the hard drive frame partition. This connection method enables tool-free installation of the hard drive backplane, avoiding the use of screws (such as flathead screws or non-removable screws in related technologies) to fix the hard drive backplane. This connection structure facilitates hard drive backplane installation, is simple to operate, saves manpower, and eliminates the need for screw management, thus facilitating maintenance. Therefore, it solves the technical problems of increased overall weight and cost due to backplane brackets and inconvenient hard drive backplane installation in related technologies, achieving the technical effect of saving server weight and cost while facilitating hard drive backplane installation.

Detailed Implementation

[0031] 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.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] 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.

[0034] The core of this invention is to provide a server that saves on the overall weight and cost of the server and facilitates the installation of hard drive backplanes.

[0035] It should be noted that in this embodiment of the invention, the first direction refers to the width direction of the server chassis 1, the second direction refers to the length direction (or depth direction or front-to-back direction) of the chassis 1, and the third direction refers to the height direction of the chassis 1. For ease of understanding, as follows... Figure 1 As shown, the first direction refers to Figure 1 The X-axis direction, the second direction refers to Figure 1 In the Y-axis direction, the third direction refers to Figure 1 The Z-axis direction in the equation.

[0036] Please refer to Figure 1 and Figure 2 This invention provides a server, including a chassis 1, a hard disk backplate 2, and a latching device 3. The chassis 1 is provided with at least two hard disk frame partitions 11 spaced apart along a first direction. The hard disk frame partitions 11 extend along a second direction, which is perpendicular to the first direction. The hard disk backplate 2 is inserted into one end of the hard disk frame partitions 11 along the second direction. The latching device 3 is provided on the hard disk backplate 2 and latches with the chassis 1.

[0037] It is understandable that the hard drive frame partition 11 is used to form the frame of the hard drive 5 to support the hard drive 5, and the spacing between any two adjacent hard drive frame partitions 11 forms a accommodating space for accommodating the hard drive 5. In addition, it is understandable that if the end of the hard drive frame partition 11 facing the front window of the chassis 1 is defined as the front end, and the end of the hard drive frame partition 11 facing the rear window of the chassis 1 is defined as the rear end, then the hard drive backplate 2 is located at the rear end of the hard drive frame partition 11.

[0038] When installing the hard drive backplate 2, align and insert the hard drive backplate 2 with the hard drive frame partition 11 to maintain the correct relative position between the hard drive backplate 2 and the hard drive frame partition 11. When the hard drive backplate 2 is installed in place, it is locked to the chassis 1 by the snap-fit ​​device 3.

[0039] In other words, in this embodiment of the invention, the hard disk backplane 2 is directly installed at one end of the hard disk frame partition 11 (the rear end of the hard disk frame partition 11), and the hard disk frame partition 11 supports the hard disk backplane 2, avoiding the need to set up a special hard disk backplane 2 bracket to support the hard disk backplane 2. That is, the hard disk backplane 2 bracket in the related technology is eliminated, reducing the overall weight and cost of the server. In addition, the hard drive backplate 2 is inserted into one end of the hard drive frame partition 11 along the second direction. This insertion ensures that the hard drive backplate 2 and the hard drive frame partition 11 maintain the correct relative position and that the hard drive backplate 2 is supported on the hard drive frame partition 11. Furthermore, the hard drive backplate 2 is snapped into the chassis 1 by the snap-fit ​​device 3, thereby fixing the hard drive backplate 2 and ensuring the stability and reliability of the relative position between the hard drive backplate 2 and the hard drive frame partition 11. This connection method enables tool-free installation of the hard drive backplate 2, avoiding the use of screws (such as flat-head screws or non-removable screws in related technologies) to fix the hard drive backplate 2. This connection structure facilitates the installation of the hard drive backplate 2, is simple to operate, saves manpower, and eliminates the need for screw management, making maintenance convenient.

[0040] It should be noted that the embodiments of the present invention do not limit the specific setting position of the latching device 3 or the specific implementation method of its connection with the chassis 1, as long as it can ensure that the hard disk backplate 2 can be connected to the chassis 1 through the latching device 3.

[0041] like Figure 1As shown, in some embodiments, the latching device 3 is located at the end of the hard disk backplate 2 along the first direction; the chassis 1 is provided with a latching bracket 4 on the inner side wall along the first direction, and the latching device 3 is latched with the latching bracket 4.

[0042] In other words, in this embodiment, the latching device 3 is located on the side of the hard drive backplate 2 along its length (width direction of the chassis 1). After the hard drive backplate 2 is installed in place, it is fixed from the side of its length. The latching device 3 is located on the side of the hard drive backplate 2 along its length, avoiding the occupation of space in the height direction (i.e., the third direction) of the chassis 1. When there are at least two hard drive backplates 2 along the third direction, it helps to avoid interference between the latching devices 3 on different hard drive backplates 2. Moreover, it is beneficial to set the snap-fit ​​bracket 4 at the inner edge of the chassis 1, which facilitates the setting of the snap-fit ​​bracket 4 and reduces the space occupied by the snap-fit ​​bracket 4 in the internal space of the chassis 1. The structural layout is reasonable, making the structure compact and the space utilization rate high. In addition, by setting the snap-fit ​​bracket 4 on the inner sidewall of the chassis 1 along the first direction, the latching device 3 snaps with the snap-fit ​​bracket 4 to fix the hard drive backplate 2. By setting the snap-fit ​​bracket 4, it is convenient to reasonably set the slot structure that cooperates with the latching device 3. Additionally, it should be noted that a latching device 3 can be provided at one end of the hard drive backplate 2 along the first direction, or a latching device 3 can be provided at both ends of the hard drive backplate 2 along the first direction.

[0043] It should be noted that this embodiment does not limit the specific structure of the snap-fit ​​bracket 4, as long as the snap-fit ​​bracket 4 can be snapped and fixed with the snap-fit ​​device 3.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, the snap-fit ​​bracket 4 includes a first mounting plate 41, a second mounting plate 42, a first protruding plate 43, a second protruding plate 44, and a connecting plate 45. The first mounting plate 41 and the second mounting plate 42 are spaced apart and are respectively attached and fixed to the inner wall of the chassis 1. The first protruding plate 43 is perpendicularly connected to the first mounting plate 41. The second protruding plate 44 is perpendicularly connected to the second mounting plate 42. The connecting plate 45 is connected between the end of the first protruding plate 43 away from the first mounting plate 41 and the end of the second protruding plate 44 away from the second mounting plate 42. An opening 46 is provided at the connection between the first protruding plate 43 and the first mounting plate 41, and the snap-fit ​​device 321 extends into the opening 46 and snaps into the first protruding plate 43.

[0045] That is to say, in this embodiment, the clamping bracket 4 has a "ji" - shaped structure, and the opening of the "ji" - shaped structure faces the inner wall of the chassis 1, making the "ji" - shaped structure protrude from the inner wall of the chassis 1, so as to facilitate the setting of the opening 46 at the connection of the first convex plate 43 and the first mounting plate 41. Since the first convex plate 43 is perpendicularly connected to the first mounting plate 41, the opening 46 is an L - shaped hole. That is, a part of the opening 46 is located on the first convex plate 43, and another part of the opening 46 is located on the first mounting plate 41. This is conducive to fully avoiding the buckle 321 of the buckle device 3, and is conducive to making the buckle 321 of the buckle device 3 extend into the opening 46 and be clamped with the position of the first convex plate 43 close to the opening 46. In addition, the first mounting plate 41 and the second mounting plate 42 are respectively fixedly adhered to the inner wall of the chassis 1, which is conducive to ensuring the stability and uniform stress of the fixation of the clamping bracket 4 to the inner wall of the chassis 1, thereby ensuring the reliability of the fixation of the clamping bracket 4 and ensuring the stable and reliable clamping between the clamping bracket 4 and the buckle device 3. The structural design of the clamping bracket 4 is ingenious, which can fully ensure the effective clamping of the buckle device 3 and the stable and reliable fixation of the clamping bracket 4.

[0046] Furthermore, as Figure 3 shown, in some embodiments, the clamping bracket 4 extends along the third direction, and the clamping bracket 4 is provided with at least two openings 46 along the third direction to be correspondingly clamped with at least two buckle devices 3. That is to say, the clamping bracket 4 in this embodiment is an integral bracket, and the corresponding number of openings 46 can be opened according to the number of buckle devices 3, so that at least two buckle devices 3 share the same clamping bracket 4. This structure is conducive to the overall forming and overall installation of the clamping bracket 4, and is convenient for the manufacturing and assembly of the clamping bracket 4. Of course, in some other embodiments, it can also be such a solution: along the third direction, the number of clamping brackets 4 is at least two, and each clamping bracket 4 corresponds to one buckle device 3. That is, the clamping brackets 4 and the buckle devices 3 are clamped correspondingly one by one. That is to say, in this embodiment, the clamping bracket 4 has a split - type structure, and the corresponding number of clamping brackets 4 can be set according to the number of buckle devices 3.

[0047] In addition, it should be noted that the specific number of the buckle devices 3 in the embodiments of the present invention is not limited. For example, a single hard - disk backplane 2 can be provided with one buckle device 3, or a single hard - disk backplane 2 can be provided with at least two buckle devices 3. The number of buckle devices 3 provided on the hard - disk backplane 2 can be determined according to the width dimension of the hard - disk backplane 2 (that is, the dimension of the hard - disk backplane 2 along the third direction). For example, as Figure 6 shown, for a 12 - port hard - disk backplane, its width dimension along the third direction is relatively large, so the 12 - port hard - disk backplane can be provided with two buckle devices 3; as Figure 7As shown, for a 4-port hard drive backplane, its width along the third direction is relatively small, so a latching device 3 can be installed on the 4-port hard drive backplane. It should be noted that a 12-port hard drive backplane refers to a hard drive backplane 2 with 12 connector interfaces, and a 4-port hard drive backplane refers to a hard drive backplane 2 with 4 connector interfaces.

[0048] Additionally, it should be noted that this embodiment does not limit the specific number of hard drive backplanes 2. In some embodiments, the number of hard drive backplanes 2 along the third direction is at least one, and each hard drive backplane 2 is provided with at least one latching device 3. For example, one hard drive backplane 2 can be provided inside the chassis 1, or at least two hard drive backplanes 2 can be provided along the third direction; for example, the server chassis 1 is provided with one 12-port hard drive backplane, or the server chassis 1 is provided with one 4-port hard drive backplane, two 4-port hard drive backplanes, three 4-port hard drive backplanes, or four 4-port hard drive backplanes.

[0049] To achieve compatibility between different hard drive backplanes 2, in some embodiments, the chassis 1 is provided with at least two snap-fit ​​structures along a third direction. The snap-fit ​​structures are used to snap-fit ​​with the corresponding latching devices 3. The hard drive backplane 2 includes a replaceable first hard drive backplane 26 and a second hard drive backplane 27. The latching devices 3 of the first hard drive backplane 26 and the second hard drive backplane 27 can respectively snap-fit ​​with at least one snap-fit ​​structure.

[0050] In other words, the chassis 1 is equipped with snap-fit ​​structures corresponding to the first hard drive backplane 26 and the second hard drive backplane 27, respectively. For example, the snap-fit ​​bracket 4 is equipped with openings 46 corresponding to the first hard drive backplane 26 and the second hard drive backplane 27, respectively. In this way, whether the first hard drive backplane 26 or the second hard drive backplane 27 is installed, the snap-fit ​​device 3 can be snapped into the chassis 1. That is to say, the server in this embodiment can be compatible with the installation of different hard drive backplanes 2. Since the chassis 1 is equipped with snap-fit ​​structures corresponding to the first hard drive backplane 26 and the second hard drive backplane 27, when the first hard drive backplane 26 is installed, the snap-fit ​​device 3 on the first hard drive backplane 26 can be snapped into the corresponding snap-fit ​​structure (such as the opening 46), and when the second hard drive backplane 27 is installed, the snap-fit ​​device 3 on the second hard drive backplane 27 can be snapped into the corresponding snap-fit ​​structure (such as the opening 46).

[0051] Furthermore, in some embodiments, the chassis 1 has a snap-fit ​​structure shared by the snap-fit ​​device 3 of the first hard drive backplane 26 and the snap-fit ​​device 3 of the second hard drive backplane 27. That is, this snap-fit ​​structure is used to snap-fit ​​with both the snap-fit ​​device 3 on the first hard drive backplane 26 and the snap-fit ​​device 3 on the second hard drive backplane 27. In other words, the snap-fit ​​device 3 on the first hard drive backplane 26 and the snap-fit ​​device 3 on the second hard drive backplane 27 are in the same position relative to the chassis 1. Thus, no matter how the hard drive backplane 2 is replaced, the snap-fit ​​position of the snap-fit ​​device 3 with the chassis 1 remains unchanged. While achieving compatibility between the first hard drive backplane 26 and the second hard drive backplane 27, it is beneficial to reduce the number of snap-fit ​​structures on the chassis 1. For example, the number of openings 46 on the snap-fit ​​bracket 4 can be reduced.

[0052] For example, the mounting bracket 4 has at least two openings 46 along a third direction, the first hard drive backplate 26 has two latching devices 3 along a third direction, and the second hard drive backplate 27 has one latching device 3. The two latching devices 3 on the first hard drive backplate 26 correspond to two of the openings 46, and the one latching device 3 on the second hard drive backplate 27 corresponds to any one of the openings 46. In this way, at least one first hard drive backplate 26 and at least one second hard drive backplate 27 can be installed.

[0053] Additionally, it is understood that the width dimensions of the first hard drive backplane 26 and the second hard drive backplane 27 along the third direction are different. Therefore, the first hard drive backplane 26 and the second hard drive backplane 27 can be replaced according to actual needs.

[0054] In addition, such as Figure 4 and Figure 5 As shown, in some embodiments, there is a gap between the second protrusion 44 and the hard disk frame partition 11 closest to the inner wall of the chassis 1, and one end of the hard disk backplate 2 is engaged with the gap.

[0055] In other words, in this embodiment, one end of the hard drive backplate 2 is inserted into the gap formed between the second protruding plate 44 and the hard drive frame partition 11 closest to the inner wall of the chassis 1. The second protruding plate 44 fits against the hard drive backplate 2, thereby limiting the hard drive backplate 2's freedom in the second direction and preventing it from wobbling in the front-back direction of the chassis 1. For example, the bright copper area of ​​the hard drive backplate 2 mates with the aforementioned gap.

[0056] In addition, such as Figure 3 and Figure 5As shown, in some embodiments, the hard disk frame partition 11 near the inner wall of the chassis 1 is provided with at least two first bent plates 111 spaced apart along a third direction. The first bent plates 111 are attached to the side of the hard disk backplate 2 facing the hard disk frame partition 11, and a clearance groove 112 is formed between two adjacent first bent plates 111 to avoid the preset structural components on the hard disk backplate 2.

[0057] In other words, this embodiment uses a first bending plate 111 at the end of the hard drive frame partition 11 near the inner wall of the chassis 1 to limit the hard drive backplate 2, restricting its degree of freedom in the second direction and preventing it from moving back and forth in that direction. Additionally, the first bending plate 111 can guide the sliding of the hard drive backplate 2 in the first direction. Furthermore, the gap between any two adjacent first bending plates 111 forms a clearance groove 112, which can be used to accommodate pre-set structural components on the hard drive backplate 2, such as LED lights.

[0058] It is understood that the first bending plate 111 and the snap-fit ​​bracket 4 are located on the same side of the chassis 1, with a gap formed between the first bending plate 111 and the snap-fit ​​bracket 4. For example, a gap is formed between the first bending plate 111 and the second protruding plate 44, and this gap is used for inserting one end of the hard drive backplate 2. Furthermore, it is understood that the first bending plate 111 is bent away from the second mounting plate 42, and the second mounting plate 42 can be inserted between the hard drive frame partition 11 with the first bending plate 111 and the inner wall of the chassis 1 to ensure the reliability of the second mounting plate 42's fixation.

[0059] Furthermore, in some embodiments, the free end of the first bending plate 111 is provided with an inclined curved edge that tilts away from the hard disk backplate 2. That is, the free end of the first bending plate 111 has a curved edge structure, which is beneficial for guiding the movement of the hard disk backplate 2 in the first direction, and is more conducive to allowing one end of the hard disk backplate 2 to enter the gap formed between the snap-fit ​​bracket 4 (such as the second protrusion 44) and the first bending plate 111.

[0060] In addition, such as Figure 5 and Figure 8 As shown, in some embodiments, one of the snap-fit ​​bracket 4 and the hard disk backplate 2 is provided with a protrusion 47, and the other is provided with a groove 21 that mates with the protrusion 47, so as to define the position of the hard disk backplate 2 in a third direction.

[0061] In other words, after the hard drive backplate 2 is installed in place, the protrusion 47 and the groove 21 fit together, and the mutual restraint between the protrusion 47 and the groove 21 restricts the hard drive backplate 2 along a third direction, thereby limiting the degree of freedom of the hard drive backplate 2 along the third direction and preventing changes in the position of the hard drive backplate 2 along the third direction. For example, the protrusion 47 is provided on the snap-fit ​​bracket 4, and the groove 21 is provided on the hard drive backplate 2. For example, the groove 21 is provided at one end of the hard drive backplate 2 along the first direction. Furthermore, it should be noted that this embodiment does not limit the specific shape of the protrusion 47 and the groove 21, as long as the shapes of the protrusion 47 and the groove 21 match and can fit together to limit the position of the hard drive backplate 2 along the third direction. For example, the groove 21 is an arc-shaped groove 21, and the protrusion 47 has a convex bridge structure. The middle position of the protrusion 47 is high, and the two ends are low. The protrusion 47 gradually slopes downward from the middle position to the two ends. In other words, the contour surface of the protrusion 47 is a convex arc-shaped contour surface. This structure is particularly suitable for the hard disk backplate 2 to slide along the first direction, so that the protrusion 47 and the groove 21 cooperate. It can be understood that when the hard disk backplate 2 slides along the first direction, the protrusion 47 and the groove 21 gradually approach each other. When the protrusion 47 just enters the groove 21, the size of the top of the protrusion 47 is smaller than the size of the groove 21, which is conducive to the smooth entry of the protrusion 47 into the groove 21. Moreover, the above-mentioned structure of the protrusion 47 and the groove 21 is conducive to guidance, so that the two can fit together more smoothly and reliably. It should be noted that this embodiment does not limit the specific number of protrusions 47 and grooves 21, as long as it can limit the hard disk backplate 2 along the third direction. In some embodiments, the snap-fit ​​bracket 4 has at least two protrusions 47 along a third direction, and the hard drive backplate 2 has at least one groove 21, so that the two or more protrusions 47 can be used to limit one or more hard drive backplates 2. For example, each hard drive backplate 2 has a groove 21, and one groove 21 corresponds to one protrusion 47, so that the same number of hard drive backplates 2 as the protrusions 47 can be installed. In addition, the protrusions 47 can be located at the position corresponding to the clearance grooves 112 formed between any two first bending plates 111 described above.

[0062] In addition, it should be noted that the above embodiments do not limit the specific structure of the latching device 3, as long as the latching device 3 can be latched and fixed with the chassis 1.

[0063] Please combine Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12In some embodiments, the latching device 3 includes a latching base 31 and a latching member 32. The latching base 31 is connected to the hard disk backplate 2. The latching member 32 is rotatably connected to the latching base 31. One end of the latching member 32 is provided with a latch 321, and the other end is provided with a pressing boss 322. The latch 321 is latched to the chassis 1, and the pressing boss 322 is used for the user to apply pressing pressure.

[0064] Understandably, the latching device 3 is mounted on the hard drive backplate 2 via the latching base 31. The latching device 3 reaches the position where it engages with the chassis 1 as the hard drive backplate 2 is installed. Before the hard drive backplate 2 is fully installed, for example, if the hard drive backplate 2 is installed from back to front in a second direction, and before the hard drive backplate 2 slides in a first direction, the pressing boss 322 is operated. This causes the pressing boss 322 to rotate the latching member 32 relative to the latching base 31, thereby preventing interference between the latching member 32 and the chassis 1 structure and affecting the installation of the hard drive backplate 2. After the hard drive backplate 2 slides into place in the first direction, the latching member 32 rotates in the opposite direction, thereby engaging and fixing the latch 321 with the chassis 1. For example, the latch 321 extends into the opening 46 of the latching bracket 4 and engages and fixes with the latching bracket 4. Furthermore, the outer side of the free end of the latch 321 is provided with a first chamfer. Understandably, the first chamfer design serves a guiding and clearance function to ensure that the latch 321 smoothly engages in the opening 46, preventing interference between the latch 321 and the solid structure of the latching bracket 4, which would hinder the latch 321's smooth entry into the opening 46. Alternatively, a chamfer or rounded corner can be provided on the wall of the opening 46 to guide the latch 321, ensuring that the latch 321 can smoothly enter and exit the opening 46.

[0065] Furthermore, such as Figure 11 As shown, in some embodiments, the buckle base 31 is provided with a first stop surface 311 and a second stop surface 312. The first stop surface 311 is used to limit the extreme position when the buckle 32 is rotated open; the second stop surface 312 is used to limit the extreme position when the buckle 32 is rotated and engaged.

[0066] It should be noted that in this embodiment, the rotational movement of the latch 321 when it disengages from the chassis 1 or the mounting bracket 4 is defined as rotational opening, and the rotational movement of the latch 321 when it is engaged with the chassis 1 or the mounting bracket 4 is defined as rotational locking. This embodiment defines the rotational limit positions of the latch 32 when it is rotated open and rotated locked by respectively setting a first stop surface 311 and a second stop surface 312. The first stop surface 311 prevents excessive pressing of the pressing boss 322 during operation; the second stop surface 312 limits the position of the latch 32 when it is engaged with the chassis 1 or the mounting bracket 4, ensuring the reliability of the position and the stability of the engagement.

[0067] It is understood that the first stop surface 311 and the second stop surface 312 have a certain height difference, forming a stepped surface to ensure that the fastener 32 has sufficient rotational travel. Furthermore, in some embodiments, the transition surface between the first stop surface 311 and the second stop surface 312 is an arc-shaped transition surface to fully avoid the rotation of the fastener 32 and prevent interference with the rotation of the fastener 32.

[0068] In addition, it should be noted that the above embodiments do not limit the specific rotational connection between the buckle 32 and the buckle base 31. As long as the buckle 32 can rotate relative to the buckle base 31, the buckle 32 can be fixed or separated from the chassis 1 or the buckle bracket 4.

[0069] like Figure 10 and Figure 11 As shown, in some embodiments, the buckle 32 is provided with two oppositely arranged support arms 323, and the opposite sides of the two support arms 323 are respectively provided with rotating shafts 324. The buckle base 31 is provided with rotating holes 313 that are rotatably connected to the two rotating shafts 324.

[0070] In other words, the rotating shafts 324 on the two support arms 323 of the snap fastener 32 are correspondingly installed in the two rotating holes 313 on the outside of the snap fastener base 31. The snap fastener rotates relative to the snap fastener base 31 by rotating the rotating shafts 324 relative to the rotating holes 313. This connection structure is simple, easy to implement, and ensures the stability of the snap fastener's rotation and the uniformity of the rotational force. To facilitate the assembly of the snap fastener 32 with the snap fastener base 31, in some embodiments, the support arms 323 are elastic support arms 323. Thus, when assembling the snap fastener 32 and the snap fastener base 31, the elastic support arms 323 can be deformed, for example, by moving the two oppositely arranged elastic support arms 323 away from each other, opening the space between the two elastic support arms 323, allowing the snap fastener 32 to snap into the snap fastener base 31, and the two rotating shafts 324 to snap into the corresponding rotating holes 313. For example, the snap fastener 32 is entirely made of elastic plastic, which facilitates the assembly of the snap fastener 32 with the snap fastener base 31. Furthermore, in some embodiments, the side of the rotating shaft 324 away from the buckle 32 is provided with a second chamfer. When assembling the buckle 32 and the buckle base 31, the inclined surface of the second chamfer abuts against the top of both sides of the buckle base 31. By applying external force to the buckle 32, the buckle base 31 is snapped between the two support arms 323, and finally the two rotating shafts 324 are snapped into the corresponding two rotating holes 313.

[0071] In addition, such as Figure 8 , Figure 10 and Figure 11As shown, in some embodiments, the buckle base 31 is provided with a first receiving cavity 314, the buckle member 32 is provided with a second receiving cavity 325, and the buckle device 3 further includes an elastic member 33, which is used to provide the buckle member 32 with an elastic force to clamp the housing 1. The two ends of the elastic member 33 are respectively provided in the first receiving cavity 314 and the second receiving cavity 325.

[0072] In other words, this embodiment uses an elastic element 33 between the snap fastener 32 and the snap fastener base 31. When the user presses the pressing boss 322, the snap fastener 32 compresses the elastic element 33, causing the elastic element 33 to undergo elastic deformation and store elastic force. When the user releases the pressing boss 322, the snap fastener 32 rotates under the elastic force of the elastic element 33, causing the snap fastener 32's snap fastener 321 to spring into the slot of the chassis 1, such as the opening 46 of the snap fastener bracket 4, so that the snap fastener 32's snap fastener 321 is snapped and fixed to the chassis 1 or the snap fastener bracket 4. This solution is simple to operate and facilitates the snap fastener 32 being snapped and fixed to the chassis 1 or the snap fastener bracket 4. Furthermore, the two ends of the elastic member 33 are respectively located within the first accommodating cavity 314 and the second accommodating cavity 325, which helps to conceal the elastic member 33 and ensures the stability of the two ends of the elastic member 33, thus limiting the movement of the two ends of the elastic member 33. Moreover, when the elastic member 33 extends or retracts, the two ends of the elastic member 33 extend or retract along the first accommodating cavity 314 and the second accommodating cavity 325 respectively, which helps to ensure the stability of the extension and retraction of the elastic member 33 and prevent the elastic member 33 from tilting. Further, in some embodiments, at least one of the first accommodating cavity 314 and the second accommodating cavity 325 is provided with a limiting post 326, which extends into the interior of the elastic member 33. That is, in this embodiment, the limiting post 326 further limits and guides the elastic member 33. In addition, it should be noted that the specific shape of the elastic member 33 is not limited in this embodiment; for example, the elastic member 33 is a spring.

[0073] In addition, the specific connection method between the buckle base 31 and the hard disk backplate 2 is not limited in the above embodiments, as long as the connection between the buckle base 31 and the hard disk backplate 2 can be realized, so that the buckle device 3 as a whole can be fixed on the hard disk backplate 2.

[0074] like Figure 8 and Figure 12 As shown, in some embodiments, the latching base 31 is provided with a threaded connection portion 315, and the latching device 3 further includes a threaded connector 34, which is connected to the threaded connection portion 315 to fix the latching device 3 to the hard disk backplate 2.

[0075] In other words, in this embodiment, the connection between the snap-fit ​​base 31 and the hard drive backplane 2 is achieved by connecting the threaded connector 34 to the threaded connection portion 315 of the snap-fit ​​base 31. It should be noted that the threaded connection portion 315 can be either an external thread or an internal thread. For example, the threaded connection portion 315 is a nut embedded in the snap-fit ​​base 31 facing the hard drive backplane 2. The hard drive backplane 2 has a mounting hole, and the threaded connector 34 is a screw. The screw passes through the mounting hole and connects with the nut, thus fixing the snap-fit ​​base 31 to the hard drive backplane 2. Alternatively, the threaded connection portion 315 can be a stud located on the snap-fit ​​base 31 facing the hard drive backplane 2. The hard drive backplane 2 has a mounting hole, and the stud passes through the mounting hole and extends out of the hard drive backplane 2 on the side away from the snap-fit ​​device 3. In this case, the threaded connector 34 can be a nut, and the connection between the nut and the stud achieves the fixing of the snap-fit ​​base 31 to the hard drive backplane 2.

[0076] In addition, to ensure that the latch base 31 and the hard drive backplate 2 have the correct relative position, such as Figure 8 and Figure 12 As shown, in some embodiments, one of the latch base 31 and the hard disk backplate 2 is provided with a positioning post 316, and the other is provided with a positioning hole 22.

[0077] In other words, when assembling the latching device 3 and the hard drive backplate 2, the positioning pin 316 and the positioning hole 22 are aligned and inserted to quickly position the latching base 31, ensuring that the latching base 31 and the hard drive backplate 2 have the correct relative position. Then, the threaded connector 34 is connected to the threaded connection part 315 to fix the latching device 3 and the hard drive backplate 2. It should be noted that the shape of the positioning pin 316 and the positioning hole 22 is not limited in this embodiment. For example, the positioning pin 316 can be a cylinder, and the positioning hole 22 can be a round hole. In addition, the specific number of positioning pins 316 and positioning holes 22 is not limited in this embodiment, as long as they can play a role in limiting the positioning of the positioning pins 316 and the positioning holes 22. In some embodiments, the number of positioning pins 316 and positioning holes 22 are two, and the two positioning pins 316 and the two positioning holes 22 are connected in a one-to-one correspondence. Further, the two positioning pins 316 are arranged side by side. In addition, by way of example, the free end of the positioning post 316 is provided with a third chamfer. It can be understood that the design of the third chamfer is beneficial to guide the positioning post 316 during the assembly process with the positioning hole 22, so that the positioning post 316 can be smoothly inserted into the corresponding positioning hole 22.

[0078] In addition, in some embodiments, the buckle base 31 is provided with a weight-reducing groove to reduce the weight of the buckle base 31.

[0079] Furthermore, the specific implementation method of connecting the hard drive backplane 2 and the hard drive frame partition 11 in the above embodiments is not limited, as long as the connection between the hard drive backplane 2 and the hard drive frame partition 11 can be achieved. Figure 8 and Figure 13 As shown, in some embodiments, one of the hard disk frame partition 11 and the hard disk backplate 2 is provided with a first gourd hole 23, and the other is provided with a first insertion limiting member 113 that cooperates with the first gourd hole 23. The sliding installation direction of the first insertion limiting member 113 relative to the first gourd hole 23 is a first direction. It should be noted that this embodiment does not limit the specific structure of the first insertion limiting member 113. For example, the first insertion limiting member 113 includes a middle rod and radial protrusions located at both ends of the middle rod. The radial protrusion at one end of the middle rod is connected to the hard disk frame partition 11 or the hard disk backplate 2, and the radial protrusion at the other end of the middle rod is a free end that can pass through the maximum diameter of the first gourd hole 23. The middle rod can slide along the length direction of the first gourd hole 23 so that the radial protrusion at the free end of the middle rod cooperates and limits the insertion of the first insertion limiting member 113 with the first gourd hole 23. It should be noted that this embodiment does not limit the specific formation method of the first insertion limiting member 113. For example, the first insertion limiting member 113 can be a first I-beam nail or a plate-shaped member formed by bending.

[0080] It is understood that the first gourd-shaped hole 23 refers to a hole resembling a gourd. The first gourd-shaped hole 23 includes a first arc-shaped hole, a second arc-shaped hole, and a straight channel connecting the first arc-shaped hole and the second arc-shaped hole. The first arc-shaped hole, the second arc-shaped hole, and the straight channel form a closed hole. The diameter of the first arc-shaped hole is greater than or equal to the maximum diameter of the first insertion limiting member 113, so that the first insertion limiting member 113 can pass through the first arc-shaped hole. The straight channel is used to connect the first arc-shaped hole and the second arc-shaped hole. The distance of the straight channel is equal to the diameter of the second arc-shaped hole, and the second arc-shaped hole is used to cooperate with the middle rod of the first insertion limiting member 113. The diameter of the second arc-shaped hole is less than the maximum diameter of the first insertion limiting member 113. When assembling the first insertion limiting member 113 with the first gourd hole 23, firstly, align the first insertion limiting member 113 with the first arc hole, for example, make the center of the first insertion limiting member 113 coincide with the center of the first arc hole, insert the first insertion limiting member 113 into the first arc hole, and then slide the middle rod of the first insertion limiting member 113 along the straight channel, so that the middle rod of the first insertion limiting member 113 slides into the second arc hole, realizing the mating connection between the first insertion limiting member 113 and the first gourd hole 23. In this embodiment, by setting the first gourd hole 23 on one of the hard disk frame partition 11 and the hard disk backplate 2, and setting the first insertion limiting member 113 on the other, the mating of the first gourd hole 23 and the first insertion limiting member 113 is used to realize the insertion assembly of the hard disk backplate 2 and the hard disk frame partition 11. Furthermore, since the sliding installation direction of the first insertion limiting member 113 relative to the first gourd hole 23 is the first direction, that is, the first arc hole and the second arc hole are distributed along the first direction, when installing the hard disk backplate 2, the hard disk backplate 2 is first pushed from back to front along the second direction to the rear end of the hard disk frame partition 11, so that the hard disk backplate 2 contacts the end of the hard disk frame partition 11. During this process, the first insertion limiting member 113 is aligned with the first arc hole of the first gourd hole 23, so that the first insertion limiting member 113 is inserted into the first arc hole. Then, the hard disk backplate 2 is pushed along the first direction, and the middle rod of the first insertion limiting member 113 slides into the second arc hole along the straight channel. When the hard disk backplate 2 slides into place along the first direction, the first insertion limiting member 113 and the second arc hole engage and lock together, so as to realize the insertion of the hard disk backplate 2 and the hard disk frame partition 11. For example, the first insertion limiting member 113 is provided on the hard disk frame partition 11, and the first gourd hole 23 is provided on the hard disk backplate 2. In addition, in order to facilitate the setting of the first insertion limiting member 113 or the first gourd hole 23, the end of the hard disk frame partition 11 is provided with a second bending plate 116. The second bending plate 116 is bent in a first direction so that the second bending plate 116 is in close contact with the hard disk backplate 2. In this way, it is convenient to set the first insertion limiting member 113 or the first gourd hole 23 on the second bending plate 116, so as to facilitate corresponding connection with the first gourd hole 23 or the first insertion limiting member 113 on the hard disk backplate 2.

[0081] In addition, such as Figure 14 As shown, in some embodiments, the hard disk frame partition 11 near the inner wall of the chassis 1 and away from the latching device 3 is provided with a stop part 114. The stop part 114 is used to align the first insertion limiting member 113 with the installation position of the first gourd hole 23 when the hard disk backplate 2 is disassembled or installed.

[0082] It should be noted that the installation position of the first gourd hole 23 refers to the first arc hole of the first gourd hole 23, and the second arc hole of the first gourd hole 23 is the limiting position of the first gourd hole 23. When the first insertion limiting member 113 is aligned with the installation position of the first gourd hole 23, that is, when the first insertion limiting member 113 is aligned with the first arc hole, it is convenient for the first insertion limiting member 113 to pass into or out of the first gourd hole 23. In other words, this embodiment uses the stop part 114 to limit the hard disk backplate 2, so as to ensure that the first insertion limiting member 113 can be aligned with the installation position of the first gourd hole 23, thereby facilitating the installation and removal of the hard disk backplate 2. When the hard disk backplate 2 is installed along the second direction, one end of the hard disk backplate 2 contacts the stop portion 114. At this time, it can be ensured that the center of the first insertion limiting member 113 coincides with the center of the first arc hole of the first gourd hole 23, so as to facilitate the alignment and insertion of the first insertion limiting member 113 and the first gourd hole 23. Then, the hard disk backplate 2 is slid away from the stop portion 114 along the first direction, so that the limiting position (i.e. the second arc hole) of the first insertion limiting member 113 and the first gourd hole 23 are aligned, and the first insertion limiting member 113 and the first gourd hole 23 are connected. When it is necessary to remove the hard drive backplate 2, slide the hard drive backplate 2 along the first direction toward the stop portion 114 until the hard drive backplate 2 abuts against the stop portion 114. At this time, it indicates that the center of the first insertion limiting member 113 coincides with the center of the first arc hole of the first gourd hole 23, and the hard drive backplate 2 can be smoothly removed along the second direction. This avoids the hard drive backplate 2 being unable to be removed from the hard drive frame partition 11 due to misalignment between the first insertion limiting member 113 and the first arc hole of the first gourd hole 23. In this case, it is necessary to repeatedly adjust the position of the hard drive backplate 2 along the first direction so that the center of the first insertion limiting member 113 coincides with the center of the first arc hole of the first gourd hole 23 before the hard drive backplate 2 can be removed. It can be seen that the setting of the stop portion 114 is conducive to the quick installation and removal of the hard drive backplate 2, improves the efficiency of the installation and removal of the hard drive backplate 2, and enhances the user's experience in installing and removing the hard drive backplate 2.

[0083] It should be noted that the specific structure of the stop part 114 is not limited in this embodiment, as long as the stop part 114 can limit the disassembly and assembly of the hard disk backplate 2. In some embodiments, the stop part 114 is a third bent plate provided on the hard disk frame partition 11, which is used to contact the side of the hard disk backplate 2 along the first direction. Further, the free end of the third bent plate is provided with an inclined part that bends toward the inner wall of the chassis 1. It can be understood that the inclined part has a guiding effect on the installation of the hard disk backplate 2 along the second direction, which is conducive to the smooth disassembly and assembly of the hard disk backplate 2 along the second direction.

[0084] In addition, in some embodiments, the difference between the internal dimension of the chassis 1 along the first direction and the length of the hard disk backplate 2 along the first direction is greater than or equal to the sliding stroke of the hard disk backplate 2 along the first direction.

[0085] In other words, in this embodiment, the length of the hard drive backplate 2 along the first direction is less than the internal dimension of the chassis 1 along the first direction, and the difference between the internal dimension of the chassis 1 along the first direction and the length of the hard drive backplate 2 along the first direction is sufficient to meet the sliding stroke requirements of the hard drive backplate 2 along the first direction, so as to avoid interference between the hard drive backplate 2 and the chassis 1 within the sliding stroke range of the first direction. It should be noted that by cutting off part of the material at one end of the conventional hard drive backplate 2, the dimension of the hard drive backplate 2 along the first direction can be reduced, which facilitates the sliding of the hard drive backplate 2 along the first direction. It should also be noted that the installation method of installing the hard drive backplate 2 along the second direction and sliding it into place along the first direction is beneficial to realize the independent installation and removal of each hard drive backplate 2. It is understandable that in related technologies, due to the installation orientation limitations of the hard drive backplane 2, or when the hard drive backplane 2 is installed on the backplane bracket and then on the hard drive 5 frame, resulting in at least two hard drive backplanes 2, multiple hard drive backplanes 2 must be removed simultaneously when one needs to be removed. However, with the technical solution of this embodiment, since the hard drive backplane 2 does not occupy additional space in other third directions whether it is installed or removed along the second direction or slid along the first direction, the installation and removal of the hard drive backplane 2 will not interfere with other hard drive backplanes 2 distributed along the third direction. Therefore, independent installation and removal of a single hard drive backplane 2 can be achieved, facilitating installation and maintenance. Furthermore, the reduced size of the hard drive backplane 2 along the first direction also helps save material costs. Figure 15 As shown, the server in this embodiment includes three second hard disk backplanes 27. The middle second hard disk backplane 27 is disassembled, that is, the latch 321 of the latching device 3 and the chassis 1 are released, and the middle second hard disk backplane 27 is slid to the right along the first direction. Then, the middle second hard disk backplane 27 can be taken out along the second direction. It can be seen that the disassembly of the middle second hard disk backplane 27 does not affect the upper and lower second hard disk backplanes 27, and it is not necessary to remove the upper and lower second hard disk backplanes 27 at the same time.

[0086] In addition, to improve the connection strength between the hard drive backplate 2 and the hard drive frame partition 11, such as Figure 9 and Figure 13 As shown, in some embodiments, one of the hard disk frame partition 11 and the hard disk backplate 2 is provided with a second gourd hole 115, and the other is provided with a second insertion limiting member 24 that mates with the second gourd hole 115. The sliding installation direction of the second insertion limiting member 24 relative to the second gourd hole 115 is a first direction. For example, the hard disk backplate 2 is provided with the second insertion limiting member 24, and the hard disk frame partition 11 is provided with the second gourd hole 115.

[0087] It should be noted that in this embodiment, the specific structure of the second gourd hole 115 is the same as that of the first gourd hole 23, and the structure of the second insertion limiting member 24 can be the same as that of the first insertion limiting member 113. The way the second gourd hole 115 and the second insertion limiting member 24 are assembled and disassembled is the same as the way the first gourd hole 23 and the first insertion limiting member 113 are assembled and disassembled. The principle that the sliding installation direction of the second insertion limiting member 24 relative to the second gourd hole 115 is the first direction is the same as the principle that the sliding installation direction of the first insertion limiting member 113 relative to the first gourd hole 23 is the first direction, and will not be described again here.

[0088] In this embodiment, one of the hard disk frame partition 11 and the hard disk backplate 2 is provided with a first gourd hole 23, and the other is provided with a first insertion limiting member 113 that cooperates with the first gourd hole 23. At the same time, one of the hard disk frame partition 11 and the hard disk backplate 2 is provided with a second gourd hole 115, and the other is provided with a second insertion limiting member 24 that cooperates with the second gourd hole 115. This increases the reliability of the connection between the hard disk backplate 2 and the hard disk frame partition 11 by increasing the number of insertion connection points between the hard disk backplate 2 and the hard disk frame partition 11.

[0089] It should be noted that for the 4-port hard drive backplane in related technologies, due to its slender shape and relatively weak strength, the deformation of the 4-port hard drive backplane during assembly is relatively large. This can cause the stress on the 4-port hard drive backplane to exceed the strain requirements of the capacitors on the board. In addition, when the 8639 U.2 connector is soldered onto the 4-port hard drive backplane, the large insertion and extraction force of the connector can cause the 4-port hard drive backplane to bend backward, resulting in insufficient overlap between the gold fingers of hard drive 5 and the connector of the 4-port hard drive backplane, or even detachment, causing hard drive 5 to be unreadable. Figure 16The figure shows a strain simulation diagram of a 4-port hard drive backplane in the related technology. The colored area in the figure represents the area where the strain exceeds 450με, that is, the area where the strain exceeds the standard after the 4-port hard drive backplane is installed. In order to increase the installation strength of the 4-port hard drive backplane in the related technology, a second gourd hole 115 can be provided on one of the hard drive frame partition 11 and the hard drive backplane 2, and a second insertion limiting member 24 that cooperates with the second gourd hole 115 can be provided on the other. This increases the number of connection points and the connection strength, thereby ensuring the reliability of the position of the hard drive backplane 2. It also prevents the ceramic capacitor of the hard drive backplane 2 from being damaged due to the insertion and removal of the hard drive 5, impact or vibration, etc., and prevents the hard drive 5 from being unreadable due to the small overlap between the hard drive 5 and the hard drive backplane 2 connector caused by the large insertion and removal force of the hard drive 5 and the hard drive backplane 2 connector.

[0090] Furthermore, such as Figure 8 As shown, in some embodiments, the hard disk backplate 2 is provided with a reinforcing strip 25. Exemplarily, the hard disk backplate 2 is provided with a metal strip. That is, in this embodiment, the structural strength of the hard disk backplate 2 is increased by adding a reinforcing strip 25 to the hard disk backplate 2.

[0091] like Figure 17 The figure shows a strain simulation diagram of the hard disk backplane 2 (such as the second hard disk backplane 27) in this embodiment. The colored areas in the figure represent strains exceeding 450με, that is, the areas where the strain exceeds the standard after the second hard disk backplane 27 is installed. By comparison... Figure 16 and Figure 17 It is obvious that Figure 17 The total area of ​​the strain-exceeding region of the second hard drive backplane 27 (which is a 4-port hard drive backplane) is significantly smaller than that of the second hard drive backplane 27. Figure 16 The total area of ​​the strain exceeding the limit in the four-port backplane of the related technology is shown. That is, by strengthening the structural strength of the hard drive backplane 2, the strain exceeding the limit of the hard drive backplane 2 can be reduced. In addition, by comparing the deformation cloud map of the hard drive backplane 2 after structural reinforcement with the deformation cloud map of the four-port backplane in the related technology, it can be seen that the maximum deformation of the hard drive backplane 2 after structural reinforcement in this embodiment is only 0.71mm, which reduces the deformation of the hard drive backplane 2.

[0092] In addition, such as Figure 3 and Figure 5 As shown, in some embodiments, the bottom of the chassis 1 is provided with a limiting guide portion 12, which is used to limit the installation of the hard disk backplate 2 in the second direction and guide the sliding of the hard disk backplate 2 in the first direction.

[0093] In other words, this embodiment uses a limiting guide 12 at the bottom of the chassis 1 to assist in the installation and limiting of the hard drive backplate 2. It can be understood that when the hard drive backplate 2 is installed from back to front along the second direction, when the hard drive backplate 2 moves to the limiting guide 12, it indicates that the hard drive backplate 2 has slid into place along the second direction. At this time, the hard drive backplate 2 is slid along the first direction. During this process, the hard drive backplate 2 slides along the first direction while conforming to the limiting guide 12.
