Description

Technical Field

[0001] This application relates to the field of hard disk tray technology, and in particular to a latching mechanism for a hard disk tray and a hard disk tray. Background Technology

[0002] Server operating systems are typically installed on M.2 solid-state drives (SSDs) mounted on the motherboard. Because the M.2 SSD is on the motherboard, accidental removal is unlikely. However, some existing servers do not have M.2 SSDs; instead, the operating system is installed on hot-swappable E1S SSDs. Therefore, E1S SSDs can be accidentally removed, which can cause system errors.

[0003] In related technologies, protective covers are typically added to the outside of the server, or warning stickers are affixed, to prevent accidental removal of E1S SSDs. While protective covers on servers can prevent accidental removal of E1S SSDs, all E1S SSDs must be covered to achieve this. Furthermore, once the protective covers are opened, the user cannot determine which SSD contains the operating system. Therefore, this method still does not effectively prevent accidental removal of the SSDs. Summary of the Invention

[0004] This application provides a latching mechanism for a hard drive tray and a hard drive tray, which can lock the hard drive tray to solve the problem of the hard drive being accidentally removed.

[0005] On one hand, this application provides a latching mechanism for a hard drive tray, including: a latching member, a locking member, and a limiting member. The latching member is rotatably mounted on the hard drive tray and has a latching portion and a snap-fit ​​portion. The snap-fit ​​portion is used to cooperate with a chassis to fix the hard drive tray inside the chassis. The locking member is mounted on the hard drive tray and has a locking opening, with the latching portion located within the locking opening. The limiting member is movably mounted on the latching member. When the limiting member is in a first position, it abuts against the locking opening to lock the latching member and the locking member together. When the limiting member is in a second position, it moves away from the locking opening, the latching member is rotatable, and the snap-fit ​​portion disengages from the chassis as the latching member rotates.

[0006] In this embodiment, a latching part is provided on the latching member, which can fix the hard drive tray inside the chassis. Simultaneously, a locking opening is provided on the locking member, allowing the latching part of the latching member to be positioned within this opening. The locking member prevents rotation of the latching member, thus preventing the latching part from arbitrarily disengaging from its corresponding position within the chassis, improving the stability of the hard drive tray during installation. Furthermore, a limiting member is provided on the latching member. When the limiting member abuts against the locking opening, the latching member and the locking member are mutually locked, preventing further movement and ensuring the latching part of the latching member is stably engaged with the chassis, thereby locking the hard drive tray. When the limiting member separates from the locking opening and is in a second position away from the locking opening, the mutual locking between the latching member and the locking member is released, and the hard drive tray can be removed from the chassis by rotating the latching member. When using the latching mechanism of the hard drive tray provided in this application embodiment, when it is necessary to disassemble the hard drive tray, the limiting member must first be moved from the first position to the second position, and then the latching part of the latching member must be disengaged from the locking position of the chassis before the hard drive tray can be removed from the chassis. The hard drive tray cannot be released from the chassis by simply pressing. In this way, the latching mechanism of the hard drive tray can lock the hard drive tray, thereby solving the problem of the hard drive being accidentally removed.

[0007] In one possible implementation of this application, the locking member is rotatably disposed on the hard disk tray, and the locking opening has a hook-lock portion and an abutment portion. The hook-lock portion is located outside the latch portion, and the abutment portion is located inside the latch portion. When the limiting member is in the first position, the limiting member abuts against the abutment portion, and the hook-lock portion abuts against the latch portion. The latch member and the locking member are mutually locked. In the direction of rotation along the latch member and movement away from the locking member, the outer side is the side of the latch portion that is farther away from the locking member.

[0008] In one possible implementation of this application, the hook-lock surface of the hook-lock portion that abuts against the latch portion has a first side and a second side. The distance between the first side and the rotation center of the locking member is less than the distance between the second side and the rotation center of the locking member. The first side is the side of the hook-lock surface that is away from the locking member, and the second side is the side of the hook-lock surface that is close to the locking member. The latch surface on the latch portion that abuts against the hook-lock portion matches the hook-lock surface.

[0009] In one possible implementation of this application, a first elastic element is provided on the locking member, which is used to drive the locking member to rotate so that the hook lock part moves toward the latch member.

[0010] In one possible implementation of this application, the latch is provided with a limiting through hole, the limiting member passes through the limiting through hole, and can move along the limiting through hole in a direction away from or towards the locking member.

[0011] In one possible implementation of this application, a stop is provided at one end of the limiting member near the locking member, and the stop is used to limit the position of the limiting member in the limiting through hole.

[0012] In one possible implementation of this application, the limiting through hole is a threaded hole, and the limiting element is a screw that matches the threaded hole.

[0013] In one possible implementation of this application, a second elastic element is provided on the latch member, which is used to drive the latch member to rotate so that the latch portion moves away from the locking member.

[0014] On the other hand, this application provides a hard disk tray, including: a fixed base and a latching mechanism for the hard disk tray provided in any of the above embodiments, wherein the latching member is rotatably disposed on the fixed base and the locking member is disposed on the fixed base.

[0015] In one possible implementation of this application, a first rotating shaft is provided on the fixed base, and a first through hole corresponding to the first rotating shaft is provided on the latching member. The latching member is rotatably mounted on the fixed base through the first through hole and the first rotating shaft. A second rotating shaft is also provided on the fixed base, and a second through hole corresponding to the second rotating shaft is provided on the locking member. The locking member is rotatably mounted on the fixed base through the second through hole and the second rotating shaft.

[0016] The hard drive tray provided in this application embodiment has the same technical effect as the latching mechanism of the hard drive tray provided in any of the above embodiments. That is, the latching member can lock the hard drive tray and the chassis, and the locking member and the latching member can form an interlock, which improves the reliability of the hard drive tray installed on the chassis and solves the problem of the hard drive being accidentally removed.

[0033] This application provides a latching mechanism for a hard disk tray, referring to... Figure 1 and Figure 2 , Figure 1 and Figure 2 These are exploded views of the latching mechanism of the hard drive tray provided in the embodiments of this application. The hard drive tray is used to support and fix hard drives, allowing them to be installed on devices such as computers and servers. After the hard drive tray is installed in its mounting position, the latching mechanism secures it in place, preventing it from being easily removed. The latching mechanism of this hard drive tray includes: a latch 1, a locking member 2, and a limiting member 3. The latch 1 is rotatably mounted on the hard drive tray and has a latching part 11 and a snap-fit ​​part 12. The snap-fit ​​part 12 engages with the chassis to fix the hard drive tray inside the chassis. The locking member 2 is mounted on the hard drive tray and has a locking opening 21. The latching part 11 of the latch 1 is located within the locking opening 21. The limiting member 3 is movably mounted on the latch 1 and is positioned opposite the locking opening 21. The corresponding position; wherein, the limiting member 3 has two position states relative to the latching member 1, and the limiting member 3 can switch between these two position states. When the limiting member 3 is in the first position, the limiting member 3 abuts against the locking opening 21, so that the latching member 1 and the locking member 2 are mutually locked. When the limiting member 3 is in the second position, the limiting member 3 moves away from the locking opening 21. At this time, both the latching member 1 and the locking member 2 can rotate. After the latching member 1 rotates, the latching part 12 disengages from the chassis as the latching member 1 rotates.

[0034] In this embodiment, a latching part 12 is provided on the latching member 1, which can fix the hard drive tray inside the chassis. Simultaneously, a locking opening 21 is provided on the locking member 2, so that the latching part 11 of the latching member 1 is located within the locking opening 21. The locking member 2 can prevent the latching member 1 from rotating, thus preventing the latching part 12 from arbitrarily disengaging from its corresponding position inside the chassis, thereby improving the stability of the hard drive tray during installation inside the chassis. Furthermore, a limiting member 3 is provided on the latch 1. When the limiting member 3 abuts against the locking opening 21, the latch 1 and the locking member 2 are mutually locked together. At this time, neither the latch 1 nor the locking member 2 can move anymore, which makes the latching part 12 of the latch 1 stably locked with the chassis, thereby realizing the locking of the hard drive tray. When the limiting member 3 separates from the locking opening 21 and the limiting member 3 is in a second position away from the locking opening 21, the mutual locking between the latch 1 and the locking member 2 is released. After rotating the latch 1, the hard drive tray can be removed from the chassis. When using the latching mechanism of the hard drive tray provided in this application embodiment, when it is necessary to remove the hard drive tray, the limiting member 3 must first be moved from the first position to the second position, and then the latching part 12 of the latching member 1 must be disengaged from the locking position of the chassis before the hard drive tray can be removed from the chassis. The hard drive tray cannot be released from the chassis by simply pressing. In this way, the latching mechanism of the hard drive tray can lock the hard drive tray, thereby solving the problem of the hard drive being accidentally removed.

[0035] In one possible implementation, refer to Figure 3 , Figure 3 This is a schematic diagram of a locking member provided in an embodiment of this application. Figure 1 , Figure 2 and Figure 3 As shown, a rotation center 22 is provided on the locking member 2, and the locking member 2 is rotatably mounted on the hard disk tray through the rotation center 22; the locking opening 21 on the locking member 2 has a hook lock portion 23 and an abutment portion 24. After the latch member 1 and the locking member 2 are assembled, the hook lock portion 23 is located outside the latch portion 11 on the latch member 1, and the abutment portion 24 is located inside the latch portion 11. In the direction of rotation along the latch member 1 and movement away from the locking member 2, the outside of the latch portion 11 is the side of the latch portion 11 that is farther away from the locking member 2, and the inside of the latch portion 11 is the side of the latch portion 11 that is closer to the locking member 2. With this structural arrangement, when the limiting member 3 is in the first position, the limiting member 3 abuts against the abutting part 24 of the locking member 2, and the hook locking part 23 of the locking member 2 abuts against the locking part 11 of the latching member 1, thereby making the latching member 1 and the locking member 2 mutually locked together.

[0036] For example, such as Figure 3As shown, the rotation center 22 of the locking member 2 can be configured as a through hole, and correspondingly, a rotating shaft adapted to the through hole can be provided on the hard disk tray; alternatively, the rotation center 22 can be configured as a rotating shaft, and a hole adapted to the rotating shaft can be provided on the hard disk tray. In this way, the locking member 2 can be rotatably mounted on the hard disk tray through the cooperation of the hole and the shaft.

[0037] A pressing part 25 is provided at the end of the locking member 2 away from the hard drive tray. The pressing part 25 is a certain distance from the rotation center 22 in the vertical direction, and the pressing part 25 is higher than the rotation center 22 in the vertical direction. When the locking member 2 needs to be rotated, the user presses the pressing part 25 on the locking member 2. The locking member 2 will be subjected to a torque. Under the action of this torque, the pressing part 25 of the locking member 2 moves around the rotation center 22 in a direction away from the latch member 1. That is, the hook locking part 23 will move in a direction away from the latching part 11 of the latch member 1, until the hook locking part 23 separates from the latching part 11.

[0038] Reference Figure 4 , Figure 4 This is a schematic diagram of the locking member provided in an embodiment of this application. In another example, the hook-lock portion 23 and the abutment portion 24 can be configured as two opposing protrusions. The hook-lock portion 23 is located at the end of the locking member 2 and can be configured as a triangular cross-section. The surface of the hook-lock portion 23 that abuts against the latch portion 11 of the latch member 1 is the hook-lock surface 231, which is a plane on the hook-lock portion 23 facing the abutment portion 24. The hook-lock surface 231 can be configured as a plane with a certain angle. The plane on the abutment portion 24 facing the hook-lock portion 23 is the plane on which the limiting member 3 abuts against the abutment portion 24. The space between the hook-lock portion 23 and the abutment portion 24 is the opening position where the locking opening 21 is located.

[0039] In this embodiment, since a hook lock portion 23 is provided in the locking opening 21 on the locking member 2, the hook lock portion 23 can cooperate with the latch portion 11 of the latch member 1 to form a first locking point between the latch member 1 and the locking member 2, so that the locking member 2 locks the latch member 1, that is, the latch member 1 can no longer rotate, thereby making the latch portion 12 stably locked with the chassis; at the same time, an abutment portion 24 is provided in the locking opening 21 on the locking member 2, and the limiting member 3 provided on the latch member 1 can abut against the abutment portion 24 to form a second locking point between the latch member 1 and the locking member 2, so that the latch member 1 locks the locking member 2, that is, the locking member 2 can no longer rotate around the rotation center 22, thereby realizing the mutual locking between the locking member 2 and the latch member 1.

[0040] In another possible implementation, such as Figure 4As shown, the hook-lock surface 231 on the hook-lock portion 23 has a first side 232 and a second side 233. The first side 232 is the side of the hook-lock surface 231 away from the main body of the locking member 2, that is, the first side 232 is located on the end side of the hook-lock portion 23. The second side 233 is the side of the hook-lock surface 231 closer to the main body of the locking member 2. The distance between the first side 232 and the rotation center 22 of the locking member 2 is less than the distance between the second side 233 and the rotation center 22. In other words, compared to the root, the end of the hook-lock portion 23 is closer to the rotation center 22, giving the hook-lock portion 23 a hook-shaped structure. The end of the hook-lock portion 23 is the end away from the main body of the locking member 2, and the root of the hook-lock portion 23 is the end of the hook-lock portion 23 connected to the main body of the locking member 2.

[0041] A first sliding surface 234 is provided on the side of the hook lock portion 23 away from the abutment portion 24. The first sliding surface 234 is provided on the hook lock portion 23 at a larger angle. The first sliding surface 234 extends from the root of the hook lock portion 23 to the end of the hook lock portion 23. The distance between the side of the first sliding surface 234 located at the end of the hook lock portion 23 and the abutment portion 24 is smaller than the distance between the side of the first sliding surface 234 located at the root of the hook lock portion 23 and the abutment portion 24. That is, the first sliding surface 234 is inclined towards the abutment portion 24.

[0042] Reference Figure 5 , Figure 5 This is a schematic diagram of a latching member provided in an embodiment of this application. Figure 1 , Figure 2 and Figure 5 As shown, a rotation center 14 is provided on the latch 1. For example, the rotation center 14 can be set as a through hole, and correspondingly, a shaft corresponding to the through hole is provided on the hard disk tray; or, the rotation center 14 can be set as a shaft structure, and a shaft hole corresponding to the shaft is provided on the hard disk tray. In this way, the latch 1 can rotate around the rotation center 14 through the cooperation of the shaft and the hole, so that the latching part 12 can be engaged or disengaged from the chassis.

[0043] like Figure 5As shown, the latch portion 11 on the latch 1 can be configured to correspond to the hook lock portion 23 of the locking member 2. For example, the latch surface 111 on the latch portion 11 that abuts against the hook lock portion 23 can be configured to be concave, that is, the distance between the side of the latch surface 111 located at the end of the latch portion 11 and the rotation center 14 is greater than the distance between the side of the latch surface 111 located at the base of the latch portion 11 and the rotation center 14, so that the latch surface 111 and the hook lock surface 231 are adapted to each other. The second sliding surface 112 on the latch portion 11 that is opposite to the latch surface 111 is configured to be an inclined plane, that is, the distance between the side of the second sliding surface 112 located at the end of the latch portion 11 and the rotation center 14 is greater than the distance between the side of the second sliding surface 112 located at the base of the latch portion 11 and the rotation center 14, so that the second sliding surface 112 and the first sliding surface 234 are adapted to each other.

[0044] In this embodiment, since the hook-locking surface 231 on the hook-locking part 23 is configured as a hook-shaped structure, and the locking surface 111 of the latching part 11 is configured as a concave structure that matches the hook-locking surface 231, when the latching member 1 and the locking member 2 are locked together by the latching part 11 and the hook-locking part 23, the hook-locking part 23 can not only press against the latching part 11 to prevent the latching member 1 from rotating, but also hook-lock the latching part 11. Thus, without the user actively rotating the locking member 2, the latching member 1 is stably locked by the locking member 2 and cannot rotate, thereby improving the reliability of the latching mechanism of the hard disk tray. Meanwhile, a second sliding surface 112 and a first sliding surface 234 are respectively provided on the latching part 11 and the hook locking part 23. When it is necessary to put the latching part 12 of the latching member 1 into the latching position, by pressing the latching part 11 end of the latching member 1, the first sliding surface 234 and the second sliding surface 112 abut against each other. Under the action of the first sliding surface 234, the second sliding surface 112 causes the locking member 2 to rotate around the rotation center 22, without needing to press the locking member 2 to make the locking member 2 rotate first. This simplifies the operation of the latching mechanism of the hard drive tray and improves the convenience of operating the latching mechanism of the hard drive tray.

[0045] In another possible implementation, such as Figure 1 and Figure 2As shown, a second receiving cavity 26 can be provided on the locking member 2, and a first elastic member 5 can be provided through the second receiving cavity 26. The first elastic member 5 is used to drive the locking member 2 to rotate around the rotation center 22, so that the hook locking part 23 of the locking member 2 moves towards the latch member 1. A limiting protrusion 27 is provided on the end of the locking member 2 away from the hook locking part 23. Correspondingly, a limiting structure corresponding to the limiting protrusion 27 is provided on the hard disk tray. The limiting protrusion 27 abuts against the limiting structure on the hard disk tray, which can limit the angle of rotation of the locking member 2 around the rotation center 22, that is, it can limit the position of the hook locking part 23 when it rotates towards the latch member 1. A first receiving cavity 15 can be provided on the latch member 1, and a second elastic member 6 can be provided through the first receiving cavity 15. The second elastic member 6 is used to drive the latch member 1 to rotate around the rotation center 14, so that the latching part 11 moves away from the locking member 2.

[0046] For example, the second receiving cavity 26 can be positioned at the rotation center 22 on the locking member 2, and the first elastic member 5 can be a torsion spring, fixed in the second receiving cavity 26 to drive the locking member 2 to rotate. Alternatively, the first receiving cavity 15 can be positioned at the rotation center 14 on the latch member 1, and the second elastic member 6 can also be a torsion spring, fixed in the first receiving cavity 15 to drive the latch member 1 to rotate. The first elastic member 5 and the second elastic member 6 can also be other elastic members such as spring sheets; this embodiment does not limit the specific type of elastic member used.

[0047] In this embodiment, since both the latch 1 and the locking member 2 are provided with receiving cavities, elastic members can be provided in the receiving cavities. The first elastic member 5 can rotate the locking member 2 to the position of locking with the latch 1 and keep it in the position of locking with the latch 1. The second elastic member 6 can rotate the latch 1 to the position of unlocking and keep it in the position of unlocking, that is, keep the latching part 12 of the latch 1 in the position of being separated from the chassis.

[0048] In another possible implementation, such as Figure 1 and Figure 2 As shown, a limiting through hole 13 is provided on the latching member 1, and a limiting member 3 is disposed in the limiting through hole 13. The limiting member 3 can move away from or towards the locking member 2 along the limiting through hole 13. At the same time, a stop member 4 is provided on the end of the limiting member 3 near the locking member 2. The stop member 4 can limit the movement position of the limiting member 3 in the limiting through hole 13.

[0049] For example, the limiting through hole 13 can be configured as a threaded hole, and this threaded hole can be configured as a countersunk threaded hole. The limiting member 3 can be a screw that matches the countersunk threaded hole. A snap-fit ​​groove 31 can be provided on the limiting member 3 near the locking member 2. The snap-fit ​​groove 31 extends in the circumferential direction of the limiting member 3. The stop member 4 can be a retaining spring, such as a C-type retaining spring, an E-type retaining spring, or a U-type retaining spring. After the limiting member 3 passes through the limiting through hole 13, the stop member 4 is snapped into the snap-fit ​​groove 31 to prevent the limiting member 3 from falling out of the limiting through hole 13.

[0050] like Figure 2 As shown, a receiving groove 131 can also be provided on the end of the limiting through hole 13 near the locking member 2. The size and shape of the receiving groove 131 are adapted to the size and shape of the stop member 4, and the stop member 4 can be accommodated by the receiving groove 131. For example, the receiving groove 131 and the limiting through hole 13 can be arranged coaxially, and the receiving groove 131 can be set as a circular groove structure.

[0051] In this embodiment, since a limiting through hole 13 is provided on the latch 1, the limiting member 3 can be placed on the latch 1 through the limiting through hole 13; at the same time, a stop member 4 is provided on the limiting member 3 to restrict the movement position of the limiting member 3 in the limiting through hole 13, so as to prevent the limiting member 3 from falling off the latch 1; and the limiting through hole 13 is set as a countersunk threaded hole, and the limiting member 13 is a screw. After the screw 13 is screwed into the countersunk threaded hole, the surface of the latch 1 can be kept flat, and the screw 13 will not protrude from the latch 1. The screw abuts against the abutting part 24 on the locking member 2 to realize the mutual locking of the locking member 2 and the latch 1.

[0052] Based on this, the embodiments of this application provide a hard disk tray, referring to... Figure 6 , Figure 7 and Figure 8 , Figure 6 , Figure 7 and Figure 8 These are all cross-sectional schematic diagrams of the hard disk trays provided in the embodiments of this application. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the hard drive tray includes a fixed base 7 and a latching mechanism for the hard drive tray provided in any of the above embodiments. The latching member 1 in the latching mechanism is rotatably mounted on the fixed base 7, and the locking member 2 is mounted on the fixed base 7.

[0053] In one possible implementation, such as Figure 1As shown, a first rotating shaft 71 is provided on the fixed base 7. The rotation center 22 on the locking member 2 can be set as a through hole adapted to the first rotating shaft 71. The locking member 2 is rotatably mounted on the fixed base 7 through the first rotating shaft 71 and the through hole. A torsion spring, which serves as the first elastic member 5, is sleeved on the first rotating shaft 71. One end of the torsion spring abuts against the fixed base 7, and the other end abuts against the locking member 2, thereby placing the locking member 2 in the locked position. A second rotating shaft 72 is provided on the locking base 7. The rotation center 14 on the latch member 1 can be set as a through hole adapted to the second rotating shaft 72. The latch member 1 is rotatably mounted on the fixed base 7 through the second rotating shaft 72 and the through hole. A torsion spring, which serves as the second elastic member 6, is sleeved on the second rotating shaft 72. One end of the torsion spring abuts against the fixed base 7, and the other end abuts against the latch member 1. Under the action of the torsion spring, the latch member 1 is placed in the unlocked position.

[0054] The process of removing and installing the hard drive tray provided in this application embodiment is as follows: Figure 6 As shown, after the hard drive tray is installed on the chassis (not shown in the figure), both the latch 1 and the locking member 2 are in the locked position. The hook lock part 23 abuts against the latch part 11, and the limiting member 3 is in the first position abutting against the abutting part 24. At this time, two locking points are formed between the latch 1 and the locking member 2. Under the pressure of the limiting member 3, the locking member 2 cannot rotate counterclockwise. Under the hook lock action of the hook lock part 23, the latch 1 cannot rotate clockwise. The latching part 12 of the latch 1 is on the outside of the fixing seat 7, that is, the latching part 12 is engaged with the chassis. In this way, neither the latch 1 nor the locking member 2 can rotate, so that the latching part 12 is stably and reliably engaged with the chassis, and the hard drive tray cannot be arbitrarily removed from the chassis, thus avoiding the problem of the hard drive being accidentally removed.

[0055] like Figure 7 As shown, when the hard drive tray needs to be removed from the chassis, firstly, the limiting member 3 needs to move away from the abutment part 24 of the locking member 2 to release the locking member 2. At this time, under the action of the first elastic member 5, the locking member 2 does not rotate counterclockwise, and the hook locking part 23 is still hooked with the latching part 11. Then, by pressing the pressing part 25 on the locking member 2, under the action of the pressing force, the locking member 2 is subjected to a counterclockwise rotation torque, and the locking member 2 rotates counterclockwise around the first rotating shaft 71, that is, the hook locking part 23 moves away from the latch member 1, and the hook locking part 23 separates from the latching part 11. At this time, as Figure 8As shown, under the action of the second elastic element 6, the latch 1 rotates clockwise around the rotation center 14, and the latching part 12 moves into the fixed seat 7, that is, the latching part 12 separates from the chassis. After the user releases the pressure on the locking part 2, the locking part 2 rotates clockwise under the action of the first elastic element 5, returning to the locked position. In this way, the hard drive tray is released from the chassis, and the hard drive tray can be removed from the chassis.

[0056] When the hard drive tray needs to be installed in the corresponding position on the chassis, firstly, the hard drive tray is placed in the corresponding position on the chassis; then, one end of the latch 1 with the locking part 11 is pressed, the first sliding surface 234 abuts against the second sliding surface 112, and under the action of the two sliding surfaces, the locking part 2 rotates counterclockwise until the hook locking part 23 contacts the locking part 11. At this time, under the action of the first elastic member 5, the locking part 2 rotates clockwise, the hook locking part 23 locks against the locking part 11, and the latching part 12 moves to the outside of the fixing seat 7 and latches against the chassis, thus fixing the hard drive tray to the chassis; finally, the limiting member 3 moves towards the abutting part 24 until it abuts against the abutting part 24 to complete the locking of the locking part 2, thereby completing the mutual locking between the locking part 2 and the latch 1, and thus completing the locking and fixing of the hard drive tray to the chassis.

[0057] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
