Description

Technical Field

[0001] This utility model relates to the field of mechanical structure technology, and in particular to a locking mechanism and a hard drive bracket. Background Technology

[0002] Hard drive modules are an indispensable part of storage servers and industrial control computers. Hard drives often need to be disassembled and installed. However, most hard drives and hard drive brackets are now fixed with screws, which require tools such as screwdrivers to operate, making the disassembly and installation process cumbersome and reducing efficiency. Utility Model Content

[0003] To solve the above problems, the locking mechanism and hard drive bracket provided by this utility model can reduce the complexity of hard drive module disassembly and assembly by setting a locking module on the sliding seat.

[0004] In a first aspect, this utility model provides a locking mechanism, which includes: a support base, a sliding seat, a movable component, a swing component, and a locking module;

[0005] The sliding seat is slidably connected to the support base, the swinging component is pivotally connected to the sliding seat, and the movable component is movably connected to the sliding seat.

[0006] The locking module includes: a button assembly;

[0007] The button assembly is mounted on the sliding base and is movably connected to the swing component, which is used to push the swing component to swing between the locking station and the unlocking station;

[0008] When the swinging component is in the locked position, the swinging component abuts against the moving component, the moving component is in the locked state, and the sliding seat is fixed to the support base; when the swinging component is in the unlocked position, the swinging component separates from the moving component, the moving component is in the unlocked state, and the sliding seat can slide relative to the support base.

[0009] Optionally, the locking module further includes: a linkage and a first elastic element;

[0010] One end of the first elastic element is connected to the sliding seat, and the other end of the first elastic element is connected to the linkage element. The linkage element is slidably connected to the sliding seat. One end of the linkage element is connected to the button assembly, and the other end of the linkage element is pivotally connected to the swing element. The first elastic element is used to drive the swing element to move from the unlocking station to the locking station through the linkage element, and to lock the swing element at the locking station or the unlocking station through the linkage element and the button assembly.

[0011] Optionally, the button assembly includes: a lock button and an unlock button;

[0012] Both the locking button and the unlocking button are slidably connected to the sliding seat along the first direction. The first elastic element applies a force toward the second direction to the linkage element so as to lock the swing element in the locking position or the unlocking position through the linkage element and the locking button. The first direction is perpendicular to the second direction.

[0013] The unlock button is used to push the linkage to move in the opposite direction to the second direction, so that the lock button can drive the swinging member to switch between the unlocking station and the locking station through the linkage and the first elastic member.

[0014] Optionally, the locking button has a protrusion at the end facing the linkage, and the linkage has a groove on the side wall away from the first elastic member.

[0015] When the swinging member is in the unlocking position, the first elastic member pushes the linkage member in the second direction toward the end of the locking button to abut against the protrusion in the first direction.

[0016] When the swinging component is in the locked position, the first elastic component pushes the linkage component to insert the protrusion into the groove in a direction opposite to the second direction.

[0017] Optionally, the first direction includes an unlocking direction and a locking direction. When the swing member is in the unlocking position, the first elastic member pushes the locking part in the linkage member to abut against the protrusion in the second direction. The locking part is the part of the linkage member located on the side of the groove facing the locking direction. The end of the unlock button facing the unlocking direction forms a guiding environment with the side wall of the linkage member.

[0018] When the unlock button moves in the unlocking direction, it pushes the linkage to move in the opposite direction to the second direction through the guide environment, so that the lock button can move in the unlocking direction.

[0019] Optionally, the locking button is sleeved around the outer periphery of the unlocking button, and the guiding environment includes: a guide boss fixed to the unlocking button facing the unlocking direction, and a guide ramp located at the end of the groove facing the unlocking direction in the linkage component, with the side of the guide boss facing the guide ramp adapted to the guide ramp.

[0020] The guide boss is located on the side of the protrusion facing the unlocking direction.

[0021] Optionally, the locking module further includes: a second elastic element and a third elastic element;

[0022] The second elastic element is located on the side of the unlock button facing the unlock direction. One end of the second elastic element is connected to the unlock button, and the other end of the second elastic element is connected to the sliding seat. The second elastic element is used to apply a force to the guide boss in the locking direction so that the protrusion abuts against the side wall of the groove in the locking direction or abuts against the sliding seat in the locking direction.

[0023] The third elastic element is located on the side of the guide boss facing the locking direction. One end of the third elastic element is connected to the guide boss, and the other end of the third elastic element facing the locking direction is connected to the locking button. The third elastic element is used to apply a force to the locking button in the locking direction so that the protrusion abuts against the side wall of the groove in the locking direction or abuts against the sliding seat in the locking direction.

[0024] Optionally, the moving part is rotatably connected to the sliding seat;

[0025] When the movable part is in the locked state, the swinging part abuts against the movable part to stop the movable part from rotating relative to the sliding seat and fix the position of the sliding seat relative to the support base.

[0026] When the movable part is in the unlocked state, the swinging part separates from the movable part, thereby releasing the swinging part from fixing the sliding seat and the bracket base through the movable part.

[0027] Optionally, the moving part is a gear, and a limit rack is fixedly provided on the swinging part. When the gear is in the locked state, the swinging part meshes with the gear through the limit rack.

[0028] A transmission rack is fixedly installed on the support base. The transmission rack extends along the sliding direction between the sliding seat and the support base, and the gear meshes with the transmission rack.

[0029] Secondly, this embodiment provides a hard drive bracket, which includes: a hard drive connector, a locking box, and a locking mechanism as described in any of the first aspects. The locking box is fixedly disposed on a sliding base, and a button assembly is installed on the locking box. The hard drive connector and the locking module are arranged along the sliding direction of the sliding base and the bracket base.

[0030] The locking mechanism and hard drive bracket provided in this embodiment of the utility model utilize the characteristic that one end of the hard drive module is limited by the hard drive connector during installation. By setting a locking module on the sliding base, the locking module locks the other end of the hard drive module. In this way, hard drive modules of different sizes can be fixed in the bracket base. Moreover, in the process of installing and removing the hard drive module by the locking module, it is only necessary to operate the button assembly to push the swinging part between the locking position and the unlocking position to realize the installation and removal of the hard drive module. The operation process is simple and effectively reduces the complexity of installing and removing hard drive modules. Attached Figure Description

[0048] Firstly, one embodiment of this utility model provides a locking mechanism, see [link to relevant documentation]. Figure 1 and Figure 2The locking mechanism includes: a bracket base 1, a sliding seat 2, a movable part 31, a swinging part 32, and a locking module 4.

[0049] The sliding base 2 is slidably connected to the support base 1, the swing member 32 is pivotally connected to the sliding base 2, and the movable member 31 is movably connected to the sliding base 2. The locking module 4 includes: a button assembly 42.

[0050] The button assembly 42 is mounted on the sliding base 2 and is movably connected to the swing member 32, used to push the swing member 32 to swing between the locking position and the unlocking position. When the swing member 32 is in the locking position, the swing member 32 abuts against the movable member 31, the movable member 31 is in the locked state, and the sliding base 2 is fixed to the support base 1; when the swing member 32 is in the unlocking position, the swing member 32 is separated from the movable member 31, the movable member 31 is in the unlocked state, and the sliding base 2 can slide relative to the support base 1.

[0051] It should be noted that the sliding seat 2 can slide and connect with the support base 1 in any direction; when the sliding seat 2 slides and connects with the support base 1 in the front-back direction, the swing member 32 can also be pivotally connected with the sliding seat 2 in one of multiple directions, such as the left-right direction or the vertical direction; when the swing member 32 is in the locking position, it can be fixed to the support base 1 by pushing one end of the movable member 31 into the slot on the support base 1 in a direction perpendicular to the sliding direction of the sliding seat 2 relative to the support base 1; when the swing member 32 is in the unlocking position, it can use the elastic element provided on itself, such as a compression spring, to make the movable member 31 disengage from the slot, or make the movable member 31 always connected to the swing member 32. During the process of the swing member 32 moving from the locking position to the unlocking position, the movable member 31 disengages from the corresponding slot under the action of the swing member 32, so as to release the fixed relationship between the sliding seat 2 and the support base 1.

[0052] It is understandable that when the fixed relationship between the sliding seat 2 and the bracket base 1 is released, the sliding seat 2 can slide relative to the bracket base 1.

[0053] The locking mechanism and hard drive bracket provided in this embodiment, combined with Figure 3 and Figure 4 By utilizing the characteristic that one end of the hard disk module 52 is limited by the hard disk connector 51 during installation, and by setting a locking module 4 on the sliding base 2, the other end of the hard disk module 52 can be locked by the locking module 4. In this way, hard disk modules 52 of different sizes can be fixed in the bracket base 1. In the process of installing and removing the hard disk module 52 by locking module 4, it is only necessary to operate the button assembly 42 to push the swinging part 32 to swing between the locking position and the unlocking position to realize the installation and removal of the hard disk module 52. This operation process is simple and effectively reduces the complexity of installing and removing the hard disk module 52.

[0054] In this embodiment, the locking module 4 includes: a lock box 41, which is fixed to the sliding base 2; a button assembly 42 is movably connected to the lock box 41 and connected to the swing member 32; both the sliding base 2 and the support base 1 are U-shaped structures, with the sliding base 2 fitted inside and adapted to the support base 1; the sliding base 2 is slidably connected to the support base 1 in the front-to-back direction; the middle part of the swing member 32 is pivotally connected to the bottom plate of the sliding base 2 in the vertical direction; the rear end of the swing member 32 is used to connect to the movable member 31; and the front end of the swing member 32 is used to connect to the button assembly 42. The movable member 31 is rotatably connected to the sliding base 2. The plane in which the movable member 31 rotates relative to the sliding base 2 is parallel to or coincides with the direction in which the sliding base 2 slides relative to the support base 1.

[0055] Combination Figure 1 and Figure 5 When the movable part 31 is in the locked state, the swinging part 32 abuts against the movable part 31 to stop the movable part 31 from rotating relative to the sliding seat 2 and fix the position of the sliding seat 2 relative to the support base 1. When the movable part 31 is in the unlocked state, the swinging part 32 separates from the movable part 31 to release the fixation of the swinging part 32 on the sliding seat 2 and the support base 1 through the movable part 31.

[0056] The swinging member 32 controls the rotation state of the movable member 31 relative to the sliding seat 2, thereby fixing the sliding seat 2 to the bracket base 1 and releasing the relative fixation between the sliding seat 2 and the bracket base 1. This not only fixes the hard disk module 52, but also fixes the sliding seat 2 to any position of the bracket base 1 in the front-back direction, improving the compatibility of the locking mechanism.

[0057] It should be noted that the swing member 32 can limit the rotation of the movable member 31 relative to the sliding seat 2 at the locking position by increasing the friction between the swing member 32 and the movable member 31. If the end of the swing member 32 connected to the movable member 31 and the surface of the movable member 31 are both made of rubber, then when the swing member 32 and the movable member 31 are in contact, the friction between them can prevent the movable member 31 from rotating relative to the sliding seat 2. The support base 1 is also provided with a rubber strip extending in the front-back direction at the position where it contacts the movable member 31, so as to increase the friction between the support base 1 and the movable member 31 when the movable member 31 is stationary relative to the sliding seat 2, thereby achieving the locking of the support base 1 and the sliding seat 2.

[0058] In this embodiment, the movable component 31 is a gear that can rotate on a horizontal plane, and a limiting rack 321 is fixedly provided on the swing component 32. When the gear is in the locked state, the swing component 32 meshes with the gear through the limiting rack 321, thus preventing the gear from rotating on the horizontal plane.

[0059] Combination Figure 1 and Figure 6A transmission rack 12 is fixedly mounted on the support base 1. The transmission rack 12 extends in the front-to-back direction, and a gear meshes with the transmission rack 12. Thus, when the swinging member 32 is in the locked position, the limiting rack 321 meshes with the gear, and the sliding seat 2 can lock its relative position to the support base 1 through the engagement of the transmission rack 12 and the gear. When the swinging member 32 is in the unlocked position, the limiting rack 321 disengages from the gear, and the sliding seat 2 can slide relative to the support base 1 in the front-to-back direction through the engagement of the transmission rack 12 and the gear.

[0060] Furthermore, in combination Figure 5 and Figure 6 The locking module 4 also includes a linkage 43 and a first elastic element 44.

[0061] One end of the first elastic member 44 is connected to the lock box 41, and the other end of the first elastic member 44 is connected to the linkage member 43. The linkage member 43 is slidably connected to the lock box 41. One end of the linkage member 43 is connected to the button assembly 42, and the other end of the linkage member 43 is pivotally connected to the swing member 32. The first elastic member 44 is used to drive the swing member 32 to move from the unlocking station to the locking station through the linkage member 43, and to lock the swing member 32 in the locking station or the unlocking station through the linkage member 43 and the button assembly 42.

[0062] It should be noted that the linkage 43 and the first elastic member 44 can be entirely located within the lock box 41, or partially located within the lock box 41. In this embodiment, the lock box 41 is a cuboid structure extending in the left-right direction and is adapted to the linkage 43. Both the linkage 43 and the first elastic member 44 are located within the lock box 41. The linkage 43 is slidably connected to the lock box 41 in the left-right direction, and the first elastic member 44 is a compression spring.

[0063] By setting the first elastic element 44 to apply a force toward the button assembly 42 to the linkage element 43, the automation level of the locking mechanism is improved, and the stability of the locking module 4 in locking the swing element 32 at the unlocking or locking position is ensured.

[0064] Furthermore, the button assembly 42 includes a lock button 421 and an unlock button 422.

[0065] Both the locking button 421 and the unlocking button 422 are slidably connected to the lock box 41 along the first direction. The first elastic member 44 applies a force toward the second direction to the linkage member 43 so as to lock the swing member 32 in the locking position or the unlocking position through the linkage member 43 and the locking button 421. The first direction is perpendicular to the second direction.

[0066] The unlock button 422 is used to push the linkage 43 to move in the opposite direction to the second direction, so that the lock button 421 can drive the swing member 32 to switch between the unlock position and the lock position through the linkage 43 and the first elastic member 44.

[0067] It should be noted that the locking button 421 and the unlocking button 422 can be inserted into the lock box 41 from different or the same directions, such as the top, front, or rear, and slide to connect with the lock box 41. In this embodiment, the first direction is the up-down direction, and the second direction is the left or right direction.

[0068] Furthermore, the first direction includes an unlocking direction and a locking direction. The locking button 421 has a protrusion 4211 at its end facing the linkage member 43, and the linkage member 43 has a groove 431 on its side wall away from the first elastic member 44. When the swing member 32 is in the unlocking position, the first elastic member 44 pushes the locking part in the linkage member 43 to abut against the protrusion 4211 in the second direction. The locking part is the portion of the linkage member 43 located on the side of the groove 431 facing the locking direction; the unlocking button 422 at its end facing the unlocking direction forms a guiding environment with the side wall of the linkage member 43.

[0069] When the unlock button 422 moves in the unlocking direction, it pushes the linkage 43 to move in the opposite direction to the second direction through the guide environment, so that the lock button 421 can move in the unlocking direction.

[0070] In this embodiment, the unlocking direction is downward, and the locking direction is upward. The locking button 421 is sleeved around the periphery of the unlocking button 422. The guiding environment includes: a guide boss 4221 fixed to the unlocking button 422 facing the unlocking direction, and a guide ramp 432 disposed in the linkage 43 at the end of the groove 431 facing the unlocking direction. The side of the guide boss 4221 facing the guide ramp 432 is adapted to the guide ramp 432; the guide boss 4221 is located on the side of the protrusion 4211 facing the unlocking direction. The guide ramp 432 is the lower surface of the linkage 433 in the groove 431.

[0071] Specifically, in combination Figure 7 and Figure 8 When the swing member 32 is in the unlocking position, the first elastic member 44 pushes the linkage member 43 to abut against the protrusion 4211 in the first direction at one end facing the locking button 421 in the second direction. When the swing member 32 is in the locking position, the first elastic member 44 pushes the linkage member 43 to insert the protrusion 4211 into the groove 431 in a direction opposite to the second direction.

[0072] By setting the protrusion 4211 and the groove 431, space can be provided for the linkage 43 to move in the left and right directions when the swinging member 32 needs to be switched between the locking position and the unlocking position.

[0073] When the swing member 32 moves from the unlocking position to the locking position, pressing the locking button 421 downwards causes the protrusion 4211 to point towards the groove 431 in the opposite direction of the second direction, thus engaging... Figure 7 and Figure 9 The linkage 43, under the action of the first elastic element 44, can insert the protrusion 4211 into the groove 431. When the protrusion 4211 is inserted into the groove 431, the right end of the linkage 43 abuts against the protrusion 4211 and stops moving to the right. At this time, the swinging element 32 moves to the locking position under the drive of the linkage 43, and then... Figure 8 .

[0074] In this embodiment, the guide boss 4221 is frustum-shaped; the locking button 421 and the unlocking button 422 are coaxially arranged; the number of the swing member 32, the movable member 31, the linkage member 43 and the first elastic member 44 are all two; each swing member 32, the movable member 31, the linkage member 43 and the first elastic member 44 is a locking link; the two locking links are symmetrically arranged on the left and right sides of the button assembly 42.

[0075] When the swinging component 32 moves from the locking position to the unlocking position, the unlocking button 422 pushes the linkage 43 to move away from the locking button 421, causing the protrusion 4211 to disengage from the groove 431, thus engaging... Figure 6 When it is necessary to abut the locking button 421 against the top of the linkage 43 located above the groove 431, the locking button 421 can be moved manually or by the elastic element. During the upward movement of the locking button 421, the unlocking button 422 needs to be moved upward simultaneously, so that when the swinging element 32 moves from the locking position to the unlocking position next time, the unlocking button 422 will again push the linkage 43 to move away from the locking button 421.

[0076] Furthermore, the locking module 4 also includes a second elastic element 45 and a third elastic element 46. The second elastic element 45 is located on the side of the unlock button 422 facing the unlocking direction. One end of the second elastic element 45 is connected to the unlock button 422, and the other end of the second elastic element 45 is connected to the sliding seat 2. The second elastic element 45 is used to apply a force towards the locking direction to the guide boss 4221, so that the protrusion 4211 abuts against the side wall of the groove 431 in the locking direction or abuts against the lock box 41 in the locking direction.

[0077] The third elastic member 46 is located on the side of the guide boss 4221 facing the locking direction. One end of the third elastic member 46 is connected to the guide boss 4221, and the other end of the third elastic member 46 facing the locking direction is connected to the locking button 421. The third elastic member 46 is used to apply a force to the locking button 421 in the locking direction so that the protrusion 4211 abuts against the side wall of the groove 431 in the locking direction or abuts against the lock box 41 in the locking direction.

[0078] In this embodiment, both the second elastic element 45 and the third elastic element 46 are compression springs. The use of the second elastic element 45 and the third elastic element 46 further enhances the automation and stability of the locking mechanism. A limiting groove 4222 is formed at the lower end of the locking button 421, and the top end of the second elastic element 45 is adapted to and inserted into the limiting groove 4222. A storage groove 4212 is formed on the bottom surface of the locking button 421, and the third elastic element 46 is located above the guide boss 4221 and within the storage groove 4212, and is sleeved around the periphery of the unlocking button 422. The limiting groove 4222 ensures the stability of the force direction of the second elastic element 45, and the storage groove 4212 ensures the stability of the force direction of the third elastic element 46.

[0079] In one alternative embodiment, combined with Figure 1 and Figure 6 Two sets of pulleys 21 are provided on each of the two outer sidewalls of the sliding seat 2 along the first direction. Each set of pulleys 21 has at least one pulley. The pulleys 21 are rotatably connected to the sliding seat 2 along the second direction. Slide rails 11 are fixedly provided on the two inner sidewalls of the bracket base 1 along the front-rear direction. The two sets of pulleys 21 on the same side are located inside the corresponding slide rails 11. The upper set of pulleys 21 contacts the lower inner sidewall of the slide rail 11, and the lower set of pulleys 21 contacts the upper inner sidewall of the slide rail 11. A limiting part 4213 is fixedly provided at the end of the locking button 421 facing the locking direction. The limiting part 4213 is used to abut against the hard disk module 52 along the unlocking direction when the locking module 4 and the hard disk connector 51 cooperate to lock the hard disk module 52, so as to limit the position of the hard disk module 52 in the first direction together with the bracket base 1. The limiting part 4213 can be a rearward protrusion, or multiple protrusions arranged around the locking button 421, or an annular protrusion located around the locking button 421.

[0080] In this embodiment, each set of pulleys 21 consists of two pulleys, but is not limited to this; the limiting part 4213 is an annular protrusion located around the locking button 421. By setting the slide rail 11 and pulleys 21, not only is the smoothness of the sliding seat 2 relative to the bracket base 1 ensured, but the stability of the connection between the sliding seat 2 and the bracket base 1 is also improved. The limiting part 4213 further enhances the stability of the locking mechanism in securing the hard drive.

[0081] The locking structure provided in this embodiment is simple and easy to operate, enabling tool-free maintenance of the hard disk module 52, shortening the disassembly and maintenance time of the hard disk module 52, improving the efficiency of disassembly and maintenance of the hard disk module 52, and avoiding wear and tear on the hard disk module 52 caused by repeated tightening of screws during disassembly and assembly.

[0082] Secondly, this embodiment provides a hard drive bracket. Combined with... Figure 1 , Figure 3 and Figure 4 The hard drive bracket includes a hard drive connector 51 and a locking mechanism as described in the first aspect. The hard drive connector 51 and the locking module 4 are arranged along the sliding direction of the slide seat 2 and the bracket base 1.

[0083] The hard disk module 52 is inserted into the hard disk connector 51 along the direction away from the locking module 4; the hard disk connector 51 can be fixedly mounted on the bracket base 1 or on other carriers.

[0084] In this embodiment, both the hard disk connector 51 and the bracket base 1 are fixedly mounted on the motherboard 53. The hard disk connector 51 is located directly behind the locking module 4 and is an M.2 slot.

[0085] The hard drive bracket works as follows:

[0086] In the unlocked state, combined Figure 5 and Figure 7 The locking button 421 and unlocking button 422 are pushed to their highest points by the second elastic member 45. The annular protrusion 4211 on the locking button 421 pushes open the linkage member 43, and the end of the linkage member 43 is connected to the front end of the swing member 32. When the linkage members 43 on both sides are pressed to both sides by the guide protrusion 4221, the swing member 32 will be affected by the lever, causing the limiting rack 321 at the rear end of the swing member 32 to disengage from the movable member 31. In this way, the movable member 31 can rotate freely, so the entire locking module 4 and the sliding seat 2 can move back and forth arbitrarily on the bracket base 1.

[0087] When the hard disk module 52 needs to be installed onto the hard disk connector 51, first move the sliding seat 2 forward to leave enough space between the sliding seat 2 and the hard disk connector 51 for installing the hard disk module 52; then insert the hard disk module 52 into the hard disk connector 51 from front to back; next, move the sliding seat 2 to a suitable position so that the locking module 4 abuts against the front end of the hard disk. In this embodiment, when the sliding seat 2 moves to the suitable position, the locking button 421 presses against the groove 431 at the front end of the hard disk module 52, combined with... Figure 3 and Figure 4Finally, pressing the locking button 421 causes the swing joint to move to the locking position under the action of the first elastic element 44 and the linkage, thus fixing the position of the sliding seat 2 on the bracket base 1. At this time, the limiting part 4213 at the top of the locking button 421 abuts against the upper surface of the hard disk module 52, and the limiting part 4213 will press the hard disk module 52 onto the bracket base 1. Simultaneously, combined with... Figure 8 and Figure 9 Since the protrusion 4211 at the bottom of the locking button 421 faces the groove 431 of the linkage 43, under the action of the first elastic member 44, the linkage members 43 on both sides will move towards the middle, and at the same time drive the swing member 32 to rotate along the cylinder on the locking box until the protrusion 4211 is inserted into the groove 431 and abuts against the linkage member 43. At this time, the swing member 32 moves to the locking position, and the limiting rack 321 at the end of the swing member 32 will engage with the movable member 31. The movable member 31 cannot rotate, and the position of the sliding seat 2 on the bracket base 1 is fixed.

[0088] When it is necessary to unlock hard drive module 52, first press the unlock button 422, and then... Figure 6 At this time, the inclined surface of the guide protrusion 4221 at the bottom of the unlock button 422 will press the linkage 43, causing the linkages 43 on both sides to move away from the unlock button 422 until the protrusion 4211 disengages from the groove 431; at the same time, the locking button 421 will be popped up by the third elastic member 46, and the protrusion 4211 will be moved above the groove 431. Meanwhile, the linkage 43 drives the swing member 32 to rotate along the cylinder on the locking box, causing the limiting rack 321 to separate from the moving member 31; when the pressing of the unlock button 422 stops, the linkages 43 on both sides clamp the lower end of the locking button 421 under the action of the corresponding first elastic member 44, that is, the top of the linkage 43 abuts against the protrusion 4211, and the unlock button 422 abuts against the lower surface of the locking rod under the action of the second elastic member 45, combined Figure 7 At the same time, the swinging component 32 moves to the unlocking station. At this time, the limiting rack 321 at the end of the swinging component 32 will separate from the moving component 31, the moving component 31 will return to its free state, and the sliding seat 2 can move back and forth along the slide rail 11 again, unlocking the hard disk module 52. Finally, just move the sliding seat 2 forward to separate the sliding seat 2 from the hard disk module 52, and the hard disk module 52 can be removed.

[0089] This embodiment provides a simple and convenient hard drive bracket locking structure, enabling tool-free maintenance of the hard drive module 52, shortening the disassembly and maintenance time of the hard drive module 52, improving the efficiency of disassembly and maintenance of the hard drive module 52, and avoiding the wear problem of the hard drive module 52 caused by repeated tightening of screws during disassembly and assembly; in addition, it also realizes that one bracket can be used to accommodate the installation of solid-state hard drive modules 52 of different lengths, such as 30mm, 110mm, 42mm, 60mm and 80mm in length.
