[0002] The hard drive bracket is an indispensable structural component of most servers. The hard drive bracket is combined with the hard drive and fixes the hard drive in the server chassis.

[0003] Server hard drives are the core carriers of data storage. A single server typically has 12-24 hard drives and requires frequent maintenance. To maintain a hard drive, first remove the drive tray from the server chassis, or pull out the drive tray before removing the hard drive from the tray. Currently, the hard drive and drive tray are connected using bolts, which is inconvenient to disassemble and install. Repeated disassembly and assembly can easily cause thread slippage, making the installation impossible, and can also easily scratch the hard drive surface. Summary of the Invention

[0028] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] It should be noted that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for ease of description and simplification of the present application. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present application. The terms "mounted," "connected," and "connected" should be interpreted broadly, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the described conditions and conditions similar to the described conditions, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°. "Equal" includes both absolute equality and approximate equality, where the acceptable deviation range for approximate equality may be, for example, that the difference between the two is less than or equal to 5% of either. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0030] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] In the prior art, the hard drive and the hard drive bracket are connected by bolts. When there are a large number of hard drives, disassembling and installing the hard drives multiple times during maintenance is very labor-intensive and inconvenient. The bolted connection method can easily damage the threads during repeated disassembly and installation, making it impossible to secure the installation.

[0032] like Figures 1 to 10 As shown, in order to solve the above technical problems, an embodiment of the present application provides a hard disk installation device, comprising:

[0033] An external bracket 1, wherein the external bracket 1 has a first mounting cavity 101 therein, and a first end of the external bracket 1 along a first direction is open to form a first mounting opening 11, and a second end of the external bracket 1 along the first direction is closed to form a stop wall 12;

[0034] The mounting box 2 is installed into the first mounting cavity 101 through the first mounting opening 11. The mounting box 2 has an openable second mounting cavity 210 for accommodating a hard disk. A first engaging groove 211 is provided on the outer wall of the mounting box 2.

[0035] The locking mechanism 3 is provided with a clamping portion 32 located in the first installation cavity 101, and when the installation box 2 is installed in the first installation cavity 101 and contacts the stop wall 12, the clamping portion 32 is correspondingly engaged with the first clamping groove 211;

[0036] The unlocking mechanism 4 is provided corresponding to the locking mechanism 3 and is used to drive the engaging portion 32 to disengage from the first engaging groove 211 .

[0037] Specifically, in some embodiments of the present application, the external bracket 1 is a rectangular frame as a whole, the first direction is the length direction of the external bracket 1, the first installation opening 11 is in the shape of a "mouth", and the lower end of the first installation opening 11 is flush with the bottom wall of the external bracket 1, the first installation opening 11 does not extend to the top wall of the external bracket 1, and the upper side wall of the first installation opening 11 plays a certain limiting role on the installation box 2, preventing the installation box 2 from falling out from the upper end of the first installation opening 11. The upper side wall of the external bracket 1 is hollowed out to facilitate observation of the internal situation of the external bracket 1. The shape of the installation box 2 is also rectangular, and the length of the installation box 2 along the first direction is consistent with the depth of the first installation cavity 101 along the first direction to ensure that the installation box 2 can be installed in the first installation cavity 101, and the height of the installation box 2 in the vertical direction is adapted to the height of the first installation opening 11, so that the installation box 2 can be installed in the first installation cavity 101 from the first installation opening 11 without jumping up and down. The width of the mounting box 2 along the second direction is less than the distance between the two side walls of the external bracket 1 along the second direction. That is, there is a gap between the two side walls of the mounting box 2 along the second direction and the two side walls of the external bracket 1 along the second direction, and the locking mechanism 3 and the unlocking mechanism 4 are both located within this gap. In some embodiments of the present application, there are two locking mechanisms 3, and the two locking mechanisms 3 are respectively arranged between the gap between one side wall of the mounting box 2 along the second direction and the corresponding side wall of the external bracket 1 along the second direction, and between the gap between the other side wall of the mounting box 2 along the second direction and the corresponding other side wall of the external bracket 1 along the second direction, and the two locking mechanisms 3 are symmetrically arranged. There are two unlocking mechanisms 4, and the two unlocking mechanisms 4 are arranged in a one-to-one correspondence with the two locking mechanisms 3. In order to facilitate the introduction of the structure and principle of the locking mechanism 3 and the unlocking mechanism 4, the following description will take one locking mechanism 3 and unlocking mechanism 4 that cooperate with each other as an example. It will be understood by those skilled in the art that the structure and principle of the other locking mechanism 3 and the unlocking mechanism 4 that cooperate with it are the same.

[0038] Since the hard disk (not shown) is placed in the installation box 2, the installation box 2 can be installed in the first installation cavity 101 of the external bracket 1, and the installation box 2 can be locked to the external bracket 1 by the locking mechanism 3 to achieve the installation and fixation of the hard disk, prevent the hard disk from moving during transportation and operation, and improve the stability of the hard disk; when the hard disk needs to be removed, the unlocking mechanism 4 can drive the clamping portion 32 to disengage from the first clamping groove 211 to unlock the external bracket 1 and the installation box 2, and then remove the installation box 2 from the first installation cavity 101, and then remove the hard disk from the installation box 2 to achieve the removal of the hard disk. This hard disk installation device seals the hard disk in the installation box 2, not only achieving the fixation of the hard disk, but also providing a certain degree of protection for the hard disk, preventing damage to the hard disk surface during installation and removal. It can achieve the installation and fixation of the hard disk without the need for screw locking, and is easy to remove and operate. When installing, the installation box 2 only needs to be pushed in until it contacts the stop wall 12, and the clamping portion 32 automatically aligns and locks; when unlocking, it can be completely removed by pressing the unlocking mechanism 4 with one hand.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the locking mechanism 3 further includes a first elastic member 31 and a mounting shaft 18. The mounting shaft 18 is protruding from the upper surface of the bottom wall of the external bracket 1. The clamping portion 32 is rotatably mounted on the mounting shaft 18. The external bracket 1 is provided with a first fixing portion, and the first elastic member 31 is connected between the first fixing portion and the clamping portion 32. When no external force is applied, the first elastic member 31 keeps the clamping portion 32 in a position where it can be engaged with the first clamping groove 211. When an external force is applied, the first elastic member 31 can compress and deform to store energy. When the external force disappears, the energy is released, causing the clamping portion 32 to return to its original position.

[0040] Specifically, in some embodiments of the present application, the first elastic member 31 includes a first spring, and the first fixing portion includes a fixing plate 17 formed on the inner side wall of the external bracket 1. Exemplarily, the fixing plate 17 can be provided on the bottom wall of the external bracket 1 or on the side wall of the external bracket 1 along the second direction. In some embodiments of the present application, a rectangular incision is provided on the side wall of the external bracket 1 along the second direction, and a fixing plate 17 is folded toward the inside of the first mounting cavity 101 at the rectangular incision. The fixing plate 17 is arranged parallel to the stop wall 12. The first spring is a tension spring or a compression spring, and the first spring is arranged along the first direction or is slightly inclined at a certain angle relative to the first direction. One end of the first spring is connected to the fixing plate 17, and the other end is connected to the clamping portion 32. When not affected by external force, the clamping portion 32 remains in the initial position under the action of the first spring. In the initial position, the clamping portion 32 can be clamped with the first clamping groove 211. When affected by external force, the clamping portion 32 rotates a certain angle and disengages from the first clamping groove 211. At this time, the first spring is stretched or compressed, resulting in elastic deformation. When the external force disappears, the first spring resets, thereby driving the clamping portion 32 to rotate to the initial position.

[0041] In other embodiments of the present application, the first elastic member 31 includes a first torsion spring, and the first fixing portion includes a buckle formed on the bottom wall of the external bracket 1. One end of the first torsion spring is connected to the buckle, and the other end is connected to the clamping portion 32. When not affected by external force, the clamping portion 32 remains in the initial position under the action of the first torsion spring. In the initial position, the clamping portion 32 can be clamped with the first clamping groove 211. When affected by external force, the clamping portion 32 rotates a certain angle and disengages from the first clamping groove 211. At this time, the first torsion spring is twisted and elastically deformed. When the external force disappears, the first torsion spring is reset, thereby driving the clamping portion 32 to rotate to the initial position.

[0042] Furthermore, in some embodiments of the present application, the clamping portion 32 includes a first connecting section 321, a second connecting section 322 and a hook section 323 which are arranged in sequence, and the first connecting section and the second connecting section 322 and the second connecting section 322 and the hook section 323 are all arranged in a V-shape, and the V-shaped opening formed between the first connecting section 321 and the second connecting section 322 faces one of the first mounting port 11 or the stop wall 12, and the V-shaped opening formed between the second connecting section 322 and the hook section 323 faces the other of the first mounting port 11 or the stop wall 12, and the connection between the first connecting section 321 and the second connecting section 322 is rotatably engaged with the mounting shaft 18, and the hook section 323 is used to clamp and engage with the first clamping groove 211.

[0043] Exemplarily, the V-shaped opening formed between the first connecting section 321 and the second connecting section 322 faces the first mounting port 11, and the opening formed between the second connecting section 322 and the hook section 323 faces the stop wall 12. When the hook section 323 is engaged with the first engaging groove 211, the hook section 323 provides a backward force to the mounting box 2 (the position of the first mounting port 11 is set as the front side, and the position of the stop wall 12 is set as the rear side), and then under the joint action of the stop wall 12, the mounting box 2 is fixed in the first mounting cavity 101.

[0044] In some embodiments of the present application, the side surface of the hook section 323 facing the first installation opening 11 is provided with an inclined guiding slope. When the installation box 2 is pushed into the first installation cavity 101, the rear end of the installation box 2 first contacts the hook section 323. The guiding slope is provided on the hook section 323, so that the guiding slope of the hook section 323 guides the installation box 2 during the continuous pushing process. The contact between the rear end of the installation box 2 and the guiding slope of the hook section 323 gradually changes to the contact between the side wall of the installation box 2 and the guiding slope of the hook section 323, until the end of the hook section 323 enters the first engaging groove 211 of the side wall of the installation box 2, thereby achieving the engaging and fixing of the engaging portion 32 and the installation box 2. At this time, the installation box 2 is fixed to the external bracket 1.

[0045] In some embodiments of the present application, the bottom wall of the external bracket 1 is provided with a positioning column 110, which abuts against one side of the first connecting section 321 facing the first mounting port 11, and the first elastic member 31 is connected to the side of the first connecting section 321 away from the first mounting port 11. Specifically, the positioning column 110 and the first elastic member 31 are on both sides of the first connecting section 321, which limits the first connecting section 321. When the installation box 2 is inserted into the external bracket 1, the clamping portion 32 rotates under the elastic force of the first elastic member 31, and the side of the first connecting section 321 facing the mounting port is blocked by the positioning column 110, preventing the clamping portion 32 from disengaging from the preset working position due to excessive rotation. The positioning column 110 and the mounting shaft 18 together constitute the rotation fulcrum of the clamping portion 32, so that the clamping portion 32 can be doubly constrained by the positioning column 110 and the mounting shaft 18, realizing stable lever-type rotation (similar to a "seesaw" structure). The cooperation of the positioning column 110 and the first elastic member 31 limits the rotation range of the clamping portion 32 by physical abutment, ensuring that the clamping hook section 323 can be accurately clamped into the first clamping groove 211 when the installation box 2 is inserted, avoiding clamping failure or loosening due to the deviation of the clamping portion 32. The combination of the positioning column 110 and the mounting shaft 18 restricts the degrees of freedom of the clamping portion 32, so that it can only rotate along the preset trajectory, reducing the risk of shaking or tilting, thereby improving the reliability of the locking mechanism 3 in a vibrating or impact environment. By limiting the excessive rotation of the clamping portion 32, abnormal friction and stress concentration between components are reduced, wear of key parts such as the clamping portion 32 and the first elastic member 31 is reduced, and the overall service life of the device is prolonged.

[0046] In some embodiments of the present application, the unlocking mechanism 4 includes an abutting rod 42 and a button 41. The abutting rod 42 is arranged in a first direction, one end of the abutting rod 42 abuts against the first connecting section 321, and the other end is connected to the button 41. The button 41 is installed at the first mounting port 11, and when subjected to pressure, the button 41 can drive the abutting rod 42 to drive the first connecting section 321 to rotate, so that the clamping hook section 323 is disengaged from the first clamping groove 211. When subjected to pressure, the button 41 can drive the abutting rod 42 to move to the rear side in the first direction. Since the rear end of the abutting rod 42 abuts against the first connecting section 321, the first connecting section 321 can be further driven to rotate to the rear side, and the clamping hook section 323 can be further driven to rotate forward, so that the clamping hook section 323 is disengaged from the first clamping groove 211, realizing the unlocking of the installation box 2. The button 41 is installed at the first mounting port 11 (the opening end of the installation box 2), and the position is ergonomic, so that a user can touch and operate it with one hand.

[0047] The abutment rod 42 is arranged along a first direction (the direction of insertion of the mounting box 2), with one end abutting the first connecting section 321 of the clamping portion 32 and the other end connected to the button 41. When the button 41 is pressed, the abutment rod 42 converts the vertical pressure of the button 41 into a driving force on the first connecting section 321, driving the clamping portion 32 to rotate about the mounting axis 18. The contact point between the abutment rod 42 and the first connecting section 321 deviates from the mounting axis 18 (the fulcrum), forming a lever structure. A small force applied to the button 41 is converted into a large driving force on the short lever arm of the clamping portion 32 through the long lever arm (the distance from the button 41 to the fulcrum), reducing the force required for user operation and achieving "touch-to-unlock."

[0048] In some embodiments of the present application, a positioning block 16 is provided in the first mounting cavity 101, and a positioning hole is provided on the positioning block 16, which is a transmission positioning hole through which the abutting rod 42 can move. There are multiple positioning blocks 16, and the multiple positioning blocks are arranged at intervals along the first direction. The positioning holes on the positioning blocks 16 cooperate with the abutting rod 42 to limit and guide the abutting rod 42, thereby preventing the abutting rod 42 from being deflected when the button 41 is pressed, thereby preventing the drive failure of the clamping part 32 caused by the offset of the abutting rod 42. The positioning block 16 supports the abutting rod 42 through the positioning hole, disperses the local stress generated when the button 41 is pressed, reduces the wear of the contact point between the abutting rod 42 and the clamping part 32, and extends the life of the component. As an independent module, the positioning block 16 can pre-adjust the position of the positioning hole, reduce the assembly accuracy requirements of the abutting rod 42, the clamping part 32, and the button 41, and improve production efficiency.

[0049] Furthermore, if Figure 3 As shown, the abutment rod 42 is provided with a first slot 421 extending along a first direction. A first slide bar 15 is provided at a corresponding position on the side wall of the external bracket 1. The first slide bar 15 is slidably disposed within the first slot 421. The cooperation between the first slot 421 and the first slide bar 15 limits the rotational freedom of the abutment rod 42, preventing it from twisting when the button 41 is pressed, ensuring that the driving force is always transmitted to the engaging portion 32 in a straight line. The first slide bar 15, serving as a fixing structure for the external bracket 1, cooperates with the first slot 421 to form a rigid "rod-slot" connection, reducing the shaking of the abutment rod 42 in a vibrating environment and improving the reliability of the unlocking mechanism 4 under harsh working conditions.

[0050] The positioning block 16, along with the first guide slot 421 and the first slide bar 15, together form a "dual guide system" for the abutment rod 42. The former constrains the lateral displacement of the abutment rod 42, while the latter constrains its rotational freedom. This dual guide system ensures that the abutment rod 42 can only move in a pure linear direction when the button 41 is pressed. This significantly improves the angular and displacement accuracy of the driven engaging portion 32, resulting in a more precise unlocking action.

[0051] like Figure 3As shown, in some embodiments of the present application, an elastic reset mechanism 5 is provided on the stop wall 12. The elastic reset mechanism 5 is compressed when the installation box 2 approaches the stop wall 12, and can provide a thrust to the installation box 2 toward the first installation opening 11 when the locking mechanism 3 is disengaged from the first engaging groove 211. The elastic reset mechanism 5 on the stop wall 12 cooperates with the hook section 323, and the hook section 323 cooperates with the first engaging groove 211 to provide a rearward force to the installation box 2, so that the installation box 2 is fixed in the external bracket 1. When the hook section 323 is disengaged from the first engaging groove 211, the elastic reset mechanism 5 provides a forward force to the installation box 2, driving the installation box 2 to move forward, and then can pop out of the first installation opening 11, thereby achieving separation of the installation box 2 from the external bracket 1.

[0052] An elastic reset mechanism 5 is mounted on the stop wall 12. When the installation box 2 is inserted, it compresses the mechanism 5, storing potential energy. When unlocked, this energy is released, pushing the installation box 2 toward the first installation opening 11. The user simply presses button 41 to unlock the drive; there's no need to manually pull out the installation box 2. The force of the elastic reset mechanism 5 automatically removes the hard drive, significantly simplifying the process. Traditionally, replacing a hard drive requires a two-step process: unlock and then pull it out. This design streamlines the process into a single, "press to unlock, eject" operation, improving efficiency (especially suitable for high-frequency replacement scenarios like server rooms).

[0053] The thrust of the elastic return mechanism 5 coordinates with the unlocking direction of the engaging portion 32 of the locking mechanism 3. When the hook segment 323 disengages the first engaging groove 211, the elastic thrust assists in separating the mounting box 2 from the external bracket 1. If the engaging portion 32 of the locking mechanism 3 is not fully disengaged due to friction or tolerances, the elastic thrust provides additional separation force, ensuring complete separation of the mounting box 2 from the external bracket 1 and avoiding a "half-unlocked" state. The elastic return mechanism 5 and the locking mechanism 3 form a closed "unlock-eject" functional loop. Even if the locking mechanism 3 loses its engagement force due to wear, the elastic thrust can still compensate for the separation force, ensuring reliable unlocking.

[0054] Specifically, the elastic reset mechanism 5 includes a second elastic member 53 and a crossbeam 52. A limit member 51 is formed on the inner sidewall of the stop wall 12. The limit member 51 has a second slide groove 511. The crossbeam 52 passes through the second slide groove 511 in the second direction and can slide in the first direction within the second slide groove 511. The second elastic member 53 is connected between the inner sidewall of the stop wall 12 and the crossbeam 52. A first protrusion 213 is provided on the upper surface of the installation box 2. The first protrusion 213 abuts against the side of the crossbeam 52 facing the first installation opening 11 to compress the second elastic member 53.

[0055] like Figure 6 and Figure 7As shown, the limiting member 51 is a flange structure formed on the inner side wall of the stop wall 12. The first end of the limiting member 51 is connected to the stop wall 12. The second end of the limiting member 51 first extends forward in a first direction, then bends upward, and finally bends backward, thereby forming a second chute 511. A gap is provided between the second end of the limiting member 51 and the stop wall 12. The width of the gap ensures that the crossbeam 52 can be installed in the second chute 511 from this gap. The crossbeam 52 is connected to the stop wall 12 by a second elastic member 53. When no external force is applied, the crossbeam 52 is retained at the front end of the second chute 511 under the action of the second elastic member 53. When the rear end of the installation box 2 moves to a position corresponding to the front end of the second slide 511, the upper surface of the installation box 2 is lower than the limiter 51, and the rear end of the installation box 2 enters below the limiter 51. The first protrusion 213 on the upper surface of the installation box 2 is higher than the lower surface of the crossbeam 52. The first protrusion 213 first contacts the front side of the crossbeam 52. As the installation box 2 is continuously pushed in, the first protrusion 213 abuts against the front side of the crossbeam 52, pushing the crossbeam 52 to move backward, while continuously compressing the second elastic member 53 to store potential energy. Until the hook section 323 is fully engaged with the first engaging groove 211, the second elastic member 53 is compressed to its shortest position, and the potential energy storage is completed. When the hook section 323 is disengaged from the first engaging groove 211, the force acting on the installation box 2 toward the rear disappears, and the second elastic reset releases the potential energy, driving the installation box 2 to pop forward.

[0056] Furthermore, in some embodiments of the present application, there are multiple stoppers 51, each of which is spaced apart along the second direction. There are multiple first protrusions 213, each of which is staggered with the multiple stoppers 51 in the second direction. The multiple stoppers 51 simultaneously provide support for the crossbeam 52 in the second direction, ensuring the stability of the crossbeam 52 during movement. The multiple first protrusions 213 simultaneously abut against the crossbeam 52, providing a stable and uniform backward force to the crossbeam 52, further ensuring the stability of the crossbeam 52 during movement.

[0057] The staggered design ensures that when the installation box 2 is inserted, multiple first protrusions 213 simultaneously abut the crossbeam 52, distributing the force exerted by the first protrusions 213 on the crossbeam 52 to multiple contact points, thus preventing deformation of the crossbeam 52 or fatigue of the elastic member caused by a single point of force. At the moment of unlocking, the elastic reset mechanism 5, through the linear motion of the crossbeam 52 and the dispersed transmission of the multiple protrusions, ensures that the installation box 2 receives a uniform and stable thrust, preventing ejection deflection or jamming due to uneven force. By reducing localized stress in the crossbeam 52 and the elastic member, the collaborative design significantly reduces the risk of component fatigue failure and extends the overall life of the elastic reset mechanism 5.

[0058] The second elastic member 53 is a second spring. There are multiple second springs, and the multiple second springs are spaced apart along the second direction.

[0059] Third guide slots 19 are provided on both side walls of the external bracket 1 along the second direction, with both ends of the crossbeam 52 slidingly engaging with the third guide slots 19. The third guide slots 19 restrict the crossbeam 52's freedom in the second direction (width), ensuring that it can only slide linearly along the first direction (insertion / ejection direction), thus preventing tilt or offset of the crossbeam 52 due to tolerances or vibrations of the mounting box 2. When the first protrusion 213 of the mounting box 2 abuts the crossbeam 52, the third guide slots 19 on both sides distribute the lateral force, preventing the crossbeam 52 from generating torque due to unilateral force, and ensuring that the thrust direction of the elastic reset mechanism 5 is always aligned with the first mounting opening 11.

[0060] like Figure 1 、 Figure 2 and Figure 11 As shown, in some embodiments of the present application, in order to ensure the stability of the installation box 2 when pushing in and pulling out, a fourth slide groove 13 and a fifth slide groove 14 are provided on the bottom wall of the external bracket 1, and the fourth slide groove 13 and the fifth slide groove 14 are both arranged along the first direction, and the fourth slide groove 13 is formed with a disengagement hole 131 at one end close to the first mounting port 11, and one end of the fifth slide groove 14 extends to the end surface at the first mounting port 11, and a second slide bar 24 and a third slide bar 25 are spaced apart on the bottom wall of the installation box 2 along the first direction, the second slide bar 24 and the fourth slide groove 13 are slidably matched and can be disengaged from the fourth slide groove 13 at the disengagement hole 131, and the third slide bar 25 is slidably matched with the fifth slide groove 14 and can slide out of the fifth slide groove 14 at one end where the fifth slide groove 14 extends to the first mounting port 11.

[0061] For example, there are two fourth slots 13 and two fifth slots 14. The number of second slide bars 24 corresponds to the number of fourth slots 13, and the number of third slide bars 25 corresponds to the number of fifth slots 14. The dual slots of the fourth and fifth slots 13, 14 constrain the sliding direction of the installation box 2 from different positions, ensuring that it can only move linearly in the first direction (insertion / ejection direction), avoiding tilting or jamming caused by tolerance or vibration of the installation box 2. The fourth slot 13 is provided with an escape hole 131 near the end of the installation opening, and the fifth slot 14 extends to the end surface of the installation opening. When unlocked, the second slide bar 24 disengages from the fourth slot 13 through the escape hole 131, and the third slide bar 25 slides out through the extended end of the fifth slot 14.

[0062] When installing the installation box 2, the second slide bar 24 is first matched with the escape hole 131 at the end of the fourth slide groove 13, and then the installation box 2 is pushed backward. The second slide bar 24 enters the fourth slide groove 13 to guide the movement of the installation box 2. During the movement of the installation box 2, the third slide bar 25 extends from the fifth slide groove 14 to one end of the first installation opening 11 and enters the fifth slide groove 14. The third slide bar 25 cooperates with the fifth slide groove 14, and the second slide bar 24 cooperates with the fourth slide groove 13, thereby achieving dual guidance of the installation box 2. When the installation box 2 is pulled out of the external bracket 1, the third slide bar 25 first escapes from the fifth slide groove 14, and then the second slide bar 24 continues to move forward along the fourth slide groove 13 until the second slide bar 24 moves to the escape hole 131. The installation box 2 is lifted upward, and the second slide bar 24 escapes from the escape hole 131, and the installation box 2 can escape from the external bracket 1.

[0063] In some embodiments of the present application, the spacing between the two fourth slots 13 is greater than the spacing between the two fifth slots 14, and the two fourth slots 13 and the two fifth slots 14 are symmetrically arranged about the centerline of the external bracket 1 along the first direction. The large spacing of the fourth slots 13 disperses the weight and operating force of the installation box 2 to the outer area, while the small spacing of the fifth slots 14 concentrates the force to the inner area. The differential spacing design between the fourth slots 13 and the fifth slots 14 is achieved through structural layout optimization and functional zoning, further improving the reliability of the entire process of sliding, unlocking, and ejecting the installation box 2.

[0064] The wide spacing of the outer fourth slots 13 provides primary guidance for the mounting box 2, dispersing lateral forces during sliding and preventing twisting of the mounting box 2 due to the deflection of the second slide bar 24. The narrow spacing of the inner fifth slots 14 assists in controlling sliding direction, forming a combined guidance system combining outer primary guidance with inner auxiliary positioning. In vibration or shock environments, the difference in spacing between the two slots disrupts the resonant frequency of the symmetrical structure, preventing abnormal wear or jamming due to resonance between the second slide bar 24 and the fourth slot 13, and between the third slot 19 and the fifth slot 14.

[0065] like Figures 8 to 10 As shown, in some embodiments of the present application, the installation box 2 includes a box body 21 and a cover 22. The box body 21 has a second installation opening, and the cover 22 covers the second installation opening to form a second installation cavity 210. One end of the cover 22 is rotatably connected to the cover 21, and the other end of the cover 22 is snap-fitted to the cover 22. One end of the cover 22 is rotatably connected to the box body 21, and the other end is fixed to the box body 21 via a snap-fit ​​structure, forming a composite structure of "rotary switch + snap-fit ​​fixation".

[0066] Specifically, the front end and the upper end of the box body 21 are both open to form a second mounting opening. The cover body 22 includes an upper cover 221, a side cover 222, and a connecting plate 223 connected between the upper cover 221 and the side cover 222. The upper cover 221 is provided corresponding to the upper end of the box body 21, the side cover 222 is provided corresponding to the front end of the cover body 22, and the connecting plate 223 is provided corresponding to the two side walls of the box body 21 along the second direction. The two side walls of the box body 21 along the second direction are provided with second engaging grooves 212, and corresponding positions of the connecting plate 223 are provided with elastic buckles 2231. When the cover body 22 is closed on the box body 21, the elastic buckles 2231 automatically engage with the second engaging grooves 212, thereby fixing the relative positions of the cover body 22 and the box body 21. When it is necessary to open the cover body 22, the elastic clip 2231 is bent outward to disengage the elastic clip 2231 from the second snap-fit ​​groove 212, thereby enabling the constrained contact between the cover body 22 and the box body 21. The cover body 22 can be opened relative to the box body 21 to expose the second installation port, and the hard disk can be installed or removed from the second installation cavity 210.

[0067] The rear end of the connecting plate 223 rotates with the sidewall of the box body 21 along the second direction. A third elastic member 23 is also disposed between the lid 22 and the box body 21. The third elastic member 23 is configured to elastically deform when the lid 22 and the box body 21 are closed, and is capable of resetting and opening the lid 22 when the snap fit between the lid 22 and the box body 21 is lost. When the lid 22 is closed on the box body 21, the third elastic member 23 is stretched. When the interaction between the second snap-fitting groove 212 and the elastic buckle 2231 is lost, the lid 22 automatically springs up under the action of the third elastic member 23, thereby automatically opening.

[0068] The rotating and snap-on cover 22, coupled with an elastic, assisted spring-open mechanism, achieves the multiple benefits of convenient operation, secure fixation, automatic opening, and strong anti-interference capabilities. This design not only improves hard drive replacement efficiency but also ensures data security and device durability through structural optimization. It is a core component of the hard drive installation system, enabling "tool-free, quick installation and removal" throughout the entire process. It is particularly suitable for storage devices that require frequent replacement and high reliability.

[0069] Some embodiments of the present application further provide a server, comprising a housing and a hard disk mounting device disposed in the housing.
