Description

Technical Field

[0001] This application relates to the technical field of network equipment, and more particularly to server racks. Background Technology

[0002] A server is a high-performance computer used to process network requests and provide services. It has a higher configuration than a regular computer, with a processor, large capacity memory and high-speed storage devices. Servers are usually set up in server racks because server racks have a standardized frame structure that can accommodate and protect servers and related network equipment. They are usually made of metal and have a sturdy shell that can provide physical protection for the equipment and prevent accidental collisions, dust intrusion, etc.

[0003] Server racks with pull-out trays have a rational internal space layout, facilitating the orderly installation of servers, switches, routers, and other equipment according to height. By stacking servers in the rack using pull-out trays, the limited space can be maximized, increasing rack density and allowing more computing devices to be accommodated in the same area. At the same time, the stacking design helps optimize airflow, and with the help of heat dissipation technologies such as hot and cold aisle sealing, it can improve heat dissipation efficiency, reduce equipment operating temperature, and ensure system stability. In addition, this layout facilitates centralized management and batch operation, simplifies cabling, and improves maintenance efficiency.

[0004] However, when servers are deployed in confined spaces, the front operating space required for the horizontal pulling out of the tray is often insufficient. Technicians may face the problem of the tray not being able to be fully pulled out, or even if it is pulled out with difficulty, the lack of front operating space may prevent the insertion and removal of hard drives, thus restricting the deployment flexibility and on-site maintenance efficiency of the server. Summary of the Invention

[0005] This application provides a server rack to at least solve the problem in related technologies where the required front operating space cannot be guaranteed when the server is deployed in a space-constrained location and the pull-out tray is pulled out horizontally.

[0006] This application provides a server rack, comprising: a cabinet having a receiving cavity; multiple sets of uprights spaced apart within the receiving cavity; multiple bracket mechanisms horizontally spaced apart in the height direction from the multiple sets of uprights, each bracket mechanism including a tray frame; and multiple tray assemblies slidably disposed on the multiple tray frames in the length direction, each tray assembly being configured to carry a hard drive and having a first state of sliding along the length direction and a second state of suspending from the outer end of the tray frame in the height direction.

[0007] This application solves the technical problem that when servers are deployed in confined spaces, the tray assembly can be slidably mounted on the tray frame along its length. By pulling the tray assembly along its length, the tray assembly can be switched from a first state to a second state where it is suspended above the outer end of the tray frame in the height direction. In the second state, no operating space needs to be reserved in front of the server rack, and technicians can easily insert and remove hard drives. Therefore, this application solves the technical problem that the required operating space in front of the tray assembly cannot be guaranteed when the server is deployed in a confined space. This improves the deployment adaptability and maintenance convenience in confined server rack environments. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0029] Existing technology provides an assembly structure for a server rack, including a rack body and a bracket. The bracket is located within the inner cavity of the rack body, and a tray is movably connected to the inner cavity of the bracket. The tray has slots on both the left and right sides inside, and movable toothed blocks are movably connected to the inner cavities of these slots. By using a combination of limiting devices, limiting shells, teeth, springs, and limiting slots, this solution addresses the problem of existing server racks, which typically include trays, power strips, casters, cable management devices, and other accessories. Typically, the bracket is located within the server rack cavity, and its surface has multiple threaded holes. The tray is bolted to the appropriate position on the bracket according to the size of the electrical components. Installing the tray requires repeatedly rotating multiple bolts to the correct position, which is time-consuming and inconvenient. However, existing server racks do not provide components for convenient tray installation.

[0030] Existing technologies also provide a server storage framework and storage server, which are horizontal tray-type layouts. This solution uses a hard drive backplane to divide the space inside the casing, and places multiple trays horizontally in the first partitioned cavity. This horizontal tray-type layout does not consider layout optimization in space-constrained scenarios, such as racks with limited depth or racks close to walls. In such cases, the server is deployed in a relatively small space, and the front operating space required to pull out the tray horizontally is often not guaranteed. Technicians may face the problem that the tray cannot be fully pulled out, or even if it is pulled out, the lack of front operating space makes it impossible to perform hard drive insertion and removal operations, which restricts the server's deployment flexibility and on-site maintenance efficiency.

[0031] To address the issue of insufficient front operating space when servers are deployed in confined spaces and the pull-out trays are horizontally extended, this application provides a server rack. The server rack has a receiving cavity within its interior, with multiple sets of uprights spaced apart within the cavity. Multiple bracket mechanisms are horizontally arranged at intervals along the height direction on the multiple sets of uprights. Each bracket mechanism includes a tray frame, and multiple tray assemblies are slidably disposed on the multiple tray frames along their length. Each tray assembly is configured to carry a hard drive, and each tray assembly has a first state of sliding along its length and a second state of suspending from the outer end of the tray frame in the height direction. Because the tray assembly can be slidably mounted on the tray frame along its length, pulling the tray assembly along its length switches it from a first state to a second state where it hangs over the outer end of the tray frame in the height direction. When the tray assembly is in the second state, there is no need to reserve operating space in front of the server rack, allowing technicians to insert and remove hard drives. Therefore, this solves the technical problem that when servers are deployed in confined spaces, the required operating space in front of the tray assembly cannot be guaranteed, thus improving the deployment adaptability and maintenance convenience in confined server rack environments.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figure 1 This is a perspective view of a server rack provided in an embodiment of this application. Figure 2 This is an exploded view of the components of a server rack provided in an embodiment of this application.

[0034] Embodiments of this application provide a server rack, such as Figure 1 and Figure 2As shown, the server rack includes a cabinet 1, multiple sets of uprights 2, multiple bracket mechanisms, and multiple tray assemblies 5. The cabinet 1 has a receiving cavity. The multiple sets of uprights 2 are spaced apart within the receiving cavity. The multiple bracket mechanisms are horizontally arranged at intervals along the height direction from the multiple sets of uprights 2, and each bracket mechanism includes a tray frame 4. The multiple tray assemblies 5 are slidably disposed on the multiple tray frames 4 along the length direction. Each tray assembly 5 is configured to carry a hard drive 11 and has a first state of sliding along the length direction and a second state of hanging from the outer end of the tray frame 4 in the height direction.

[0035] According to an embodiment of this application, the height direction is the extending direction of the column 2 (i.e., as shown in the example). Figure 1 The Z direction shown is the length direction. Figure 1 The Y direction shown has a width direction of... Figure 1 The X direction shown Figure 1 The X, Y, and Z directions are orthogonal to each other.

[0036] According to an embodiment of this application, each set of columns 2 extends along the height direction, and multiple sets of columns 2 are spaced apart in the length direction within the receiving cavity. Multiple bracket mechanisms are horizontally arranged at intervals in the height direction on the multiple sets of columns 2.

[0037] According to the embodiments of this application, since the tray assembly 5 can be slidably disposed on the tray frame 4 in the length direction, the tray assembly 5 can be pulled out along the length direction, so that the tray assembly 5 switches from the first state to the second state in the height direction, which is suspended from the outer end of the tray frame 4. When the tray assembly 5 is in the second state, the hard disk 11 is installed on the tray assembly 5. At this time, there is no need to reserve operating space in front of the server rack, and technicians can complete the insertion and removal of the hard disk 11. Therefore, it can solve the technical problem that when the server is deployed in a space with relatively small space, the tray assembly 5 cannot be fully pulled out along the length direction, or even if the tray assembly 5 can be pulled out along the length direction, the hard disk 11 cannot be inserted and removed due to insufficient operating space in front of the server rack. This achieves the technical effect of improving the deployment adaptability and maintenance convenience in a small server rack environment.

[0038] Figure 3 This is a partial perspective view of a server rack provided in an embodiment of this application, showing a tray rack and a tray assembly in a first state.

[0039] According to embodiments of this application, such as Figure 2 and Figure 3As shown, each pallet rack 4 includes a first mounting portion 41, two first support arms 42, and two slide rails 44. The first mounting portion 41 is mounted on the inner end of the rack mechanism. The two first support arms 42 extend from the first mounting portion 41 along the length direction. The two slide rails 44 are respectively mounted on the inner side of the two first support arms 42 to slidably support the pallet assembly 5.

[0040] According to an embodiment of this application, the first mounting part 41 includes a body part and a support part. The body part is mounted on the inner end of the bracket mechanism, and the support part extends from the first mounting part 41 along the length direction and is located between the two first support arms 42.

[0041] According to an embodiment of this application, two slide rails 44 are respectively installed on the inner side of two first support arms 42, and both slide rails 44 extend along the length direction to slidably support the tray assembly 5, so that the tray assembly 5 can slide along the length direction on the two slide rails 44.

[0042] According to embodiments of this application, such as Figure 3 As shown, each slide rail 44 includes a mounting plate 440 and a support plate 441. The mounting plate 440 is mounted on the first support arm 42 and extends along its length. The support plate 441 is connected to the mounting plate 440 and extends away from the first support arm 42 along its width, such that the tray assembly 5 slides on the support plate 441 along its length.

[0043] According to an embodiment of this application, a mounting plate 440 is mounted on a first support arm 42, and a support plate 441 is connected to the mounting plate 440 and extends away from the first support arm 42 in the width direction. Each slide rail 44 is configured in a generally "L" shape. The support plates 441 of the two slide rails 44 can slidably support the tray assembly 5.

[0044] According to embodiments of this application, such as Figure 3 As shown, each tray assembly 5 includes a main body 51, two hooks 52, and two reversing protrusions. Two support edges of the main body 51 in the width direction are slidably supported on two support plates 441, and the main body 51 is configured to carry the hard disk 11. The two hooks 52 are respectively mounted on the inner ends of the two support edges and extend in the width direction to slidably abut against the mounting plates 440. Each hook 52 includes a guide plate 520 extending in the length direction and spaced apart from the support plates, and a reversing plate curved from the inner end of the guide plate 520 toward the support plates 441. The two reversing protrusions are respectively mounted on the outer ends of the two mounting plates 440, and each reversing protrusion is configured to guide the main body 51 from a first state to a second state when the main body 51 slides until the guide plate 520 of the hook 52 passes over the reversing protrusion and the reversing plate abuts against the reversing protrusion.

[0045] According to an embodiment of this application, two support edges of the main body 51 in the width direction extend upward in the height direction to limit the position of the hard disk 11 carried on the main body 51, and the bottom of the two support edges are slidably supported on two support plates 441.

[0046] According to an embodiment of this application, two hooks 52 are respectively installed at the inner ends of two support edges by fasteners, such as bolts.

[0047] According to an embodiment of this application, the guide plate 520 and the support plate 441 are arranged at intervals, and one side of the guide plate 520 slides against the mounting plate 440. The support edges on both sides of the main body 51 have gaps between them and the two mounting plates 440. When the technician pulls the main body 51 to slide, the guide plate 520 with hook 52 slides against the mounting plate 440 under the action of the main body 51. The guide plate 520 first passes over the upper part of the reversing protrusion, and then the reversing plate abuts against the reversing protrusion. At this time, the gaps between the support edges on both sides of the main body 51 and the two mounting plates 440 provide accommodating space for the reversing protrusion.

[0048] According to an embodiment of this application, the surface of the main body 51 is also provided with a handle so that a technician can switch the main body 51 from the first state to the second state by holding the handle.

[0049] Figure 4 This is a partial perspective view of a server rack provided in an embodiment of this application, showing a commutator wheel, gears, drive mechanism, and lighting device. Figure 5 A partial perspective view of a server rack provided in an embodiment of this application shows a tray rack and a tray assembly in a second state.

[0050] According to embodiments of this application, such as Figure 4 As shown, each reversing protrusion is provided with a reversing wheel 53, and each reversing plate is constructed in an arc shape to cooperate with the reversing wheel 53.

[0051] According to embodiments of this application, such as Figure 3 and Figure 5 As shown, when the main body 51 slides until the guide plate 520 of the hook 52 passes over the reversing wheel 53 and the arc-shaped reversing plate abuts against the reversing wheel 53, the reversing wheel 53 can guide the main body 51 to switch more smoothly from the first state to the second state. When the main body 51 is in the second state, the arc-shaped reversing plate is hooked on the outside of the reversing wheel 53, and the arc-shaped reversing plate can limit the position of the main body 51 in the height direction when it is in the second state.

[0052] Figure 6 This is a partial perspective view of a server rack provided in an embodiment of this application, showing hooks, gears, drive mechanisms, and lighting devices.

[0053] According to embodiments of this application, such as Figure 6 As shown, each mounting plate 440 has a limiting protrusion at its outer end, and the hook 52 is located between the limiting protrusion and the reversing protrusion.

[0054] According to an embodiment of this application, when the main body 51 slides until the guide plate 520 of the hook 52 passes over the upper part of the reversing protrusion, the guide plate 520 is located between the limiting protrusion and the reversing protrusion, and the limiting protrusion can restrict the movement of the guide plate 520 in the height direction. When the reversing plate 521 abuts against the reversing protrusion and the main body 51 switches from the first state to the second state, the reversing plate 521 is located between the limiting protrusion and the reversing protrusion, and the limiting protrusion can restrict the movement of the reversing plate 521 in the height direction, thereby restricting the movement of the main body 51 in the height direction.

[0055] According to embodiments of this application, such as Figure 6 As shown, each hook 52 has a toothed portion on the outer side of its guide plate 520 and reversing plate 521. Each limiting protrusion has a gear 54 that meshes with the toothed portion, so that the gear 54 rotates under the drive of the hook 52.

[0056] According to an embodiment of this application, when the main body 51 slides until the guide plate 520 of the hook 52 passes over the upper part of the reversing protrusion, the guide plate 520 is located between the gear 54 and the reversing protrusion. The gear 54 can restrict the movement of the guide plate 520 in the height direction on the one hand, and can mesh with the toothed part on the outer side of the guide plate 520 on the other hand, and rotate under the drive of the toothed part on the outer side of the guide plate 520, thereby ensuring the stable sliding of the guide plate 520.

[0057] According to an embodiment of this application, when the reversing plate 521 abuts against the reversing protrusion and the main body 51 switches from the first state to the second state, the reversing plate 521 is located between the gear 54 and the reversing protrusion. The gear 54 can restrict the movement of the reversing plate 521 in the height direction, thereby restricting the movement of the main body 51 in the height direction. On the other hand, the gear 54 can mesh with the toothed portion on the outer side of the reversing plate 521 and rotate under the drive of the toothed portion on the outer side of the reversing plate 521, which can ensure that the main body 51 can stably switch from the first state to the second state.

[0058] According to embodiments of this application, such as Figures 1 to 6As shown, the server rack also includes one or two lighting devices 6 and one or two drive mechanisms 55. One or two lighting devices 6 are rotatably mounted above the tray assembly 5 on two mounting plates 440 or the first support arm 42. One or two drive mechanisms 55 are configured to trigger the lighting devices 6 to emit light with the rotation of gears 54, illuminating the surface of the main body 51 in the second state along the height direction.

[0059] According to an embodiment of this application, one or two lighting devices 6 are rotatably mounted on two mounting plates 440 or a first support arm 42 above the tray assembly 5 via a pivot.

[0060] According to an embodiment of this application, the drive mechanism 55 triggers the lighting device 6 to emit light as the gear 54 rotates. After being triggered to emit light, the lighting device 6 directionally illuminates the surface of the main body 51 in the second state along the height direction, which can ensure the visibility of technicians in low-light environments and significantly improve the efficiency and accuracy of maintenance work on the hard drive 11 in the server rack.

[0061] According to embodiments of this application, such as Figure 6 As shown, each drive mechanism 55 includes a movable rack 550 and a drive unit 551. The movable rack 550 is slidably mounted on the mounting plate 440 or the first support arm 42 and extends along its length. The movable rack 550 meshes with a gear 54 to move along its length toward the inner end of the mounting plate 440 while the toothed portion drives the gear 54 to rotate. The drive unit 551 extends downward from the outer end of the movable rack 550 toward the lighting device 6 to drive the lighting device 6 to rotate and trigger the lighting device 6 to emit light when the movable rack 550 moves toward the inner end of the mounting plate 440.

[0062] According to an embodiment of this application, the movable rack 550 drives the gear 54 to rotate while moving along its length toward the inner end of the mounting plate 440. When the movable rack 550 moves toward the inner end of the mounting plate 440, the drive unit 551 drives the lighting device 6 to rotate axially around the pivot axis and triggers the lighting device 6 to emit light. The automated coordinated action of the main body 51 moving along its length, the lighting device 6 rotating, and the lighting effect being triggered is achieved through the linkage design of the hook 52, the reversing wheel 53, the gear 54, and the drive mechanism 55.

[0063] According to an embodiment of this application, an electrical contact is provided within the mounting plate 440 or the first support arm 42, and the electrical contact is electrically connected to an external power supply device. When the moving rack 550 does not move along its length toward the inner end of the mounting plate 440, the contact on the rotating shaft of the lighting device 6 does not contact the electrical contact provided within the mounting plate 440 or the first support arm 42, and the lighting device 6 does not emit light. When the moving rack 550 moves along its length toward the inner end of the mounting plate 440, the drive unit 551 drives the lighting device 6 to rotate axially around the rotating shaft as the moving rack 550 moves toward the inner end of the mounting plate 440. The rotating shaft connected to the lighting device 6 rotates under the drive of the lighting device 6, and the contact on the rotating shaft rotates until it contacts the electrical contact provided within the mounting plate 440 or the first support arm 42, forming a closed circuit. At this time, the external power supply device supplies power to the lighting device 6, and the lighting device 6 emits light.

[0064] According to an embodiment of this application, the server rack further includes a magnetic chuck 7. The magnetic chuck 7 is disposed on the first mounting portion 41 to hold the main body portion 51 in a second state by magnetic force.

[0065] According to embodiments of this application, such as Figure 3 and Figure 5 As shown, the magnetic suction member 7 is constructed as a column, located at the bottom of the support portion of the first mounting portion 41, and extends from the support portion along its length. A magnet is installed at the end of the magnetic suction member 7 to magnetically attract the main body portion 51, which is suspended from the outer ends of the two support plates 441 in the height direction. This allows the main body portion 51 to be stably held in the second state, facilitating the installation of the hard drive 11 by technicians. Therefore, when the server is deployed in a relatively confined space, no operating space in front of the server rack is required, allowing technicians to easily insert and remove the hard drive 11. Furthermore, by stably holding the main body portion 51 in the second state using the magnetic suction member 7, vibrations caused by accidental shaking of the server rack or accidental closing of the server rack doors can be prevented, ensuring the safety of technicians when inserting or removing the hard drive 11.

[0066] According to embodiments of this application, such as Figure 3 and Figure 5 As shown, the server rack also includes a power supply device 8, which is installed on the side of the first mounting part 41 away from the two first support arms 42. The power supply device 8 is suitable for supplying power to the hard drives installed on the main body part 51.

[0067] According to embodiments of this application, the power supply device 8 may be selected as, for example, a power source (e.g., a battery).

[0068] According to embodiments of this application, such as Figure 3 and Figure 5As shown, the server rack also includes a cable management board 9, which is installed in the first mounting section 41 and located between the two first support arms 42. The cable management board 9 has a cable management groove that extends in the width direction to allow cables connecting the hard drive 11 and the power supply device 8 to pass through, so that the hard drive 11 and the power supply device 8 are electrically connected.

[0069] According to the embodiments of this application, a cable management board 9 is provided on the tray rack 4, which enables modular cabling management, keeps the cables inside the server rack neat and orderly, realizes the partitioned storage of cables between the hard drive 11 and the power supply device 8, avoids the impact of cable tangling on airflow organization, maintains an optimized heat dissipation channel inside the server rack, and improves the heat dissipation efficiency inside the server rack.

[0070] According to embodiments of this application, such as Figure 2 As shown, each bracket mechanism also includes a bracket 3 mounted on the column 2, and a pallet frame 4 mounted on the bracket 3.

[0071] According to an embodiment of this application, the bracket 3 can be installed on the column 2 by snap-fit, and the pallet frame 4 can be installed on the bracket 3 by snap-fit, which can limit the position of the pallet frame 4 on the bracket 3.

[0072] According to an embodiment of this application, each pallet holder 4 further includes two operating elements 43, each operating element 43 being mounted on the outer end of the first support arm 42 and the bracket 3.

[0073] According to an embodiment of this application, one end of the two operating members 43 is connected to the opposite side of the two first support arms 42, and the other end of the two operating members 43 extends in the opposite direction along the width and is connected to the outer end of the bracket 3 to fix the tray frame 4 on the bracket 3, so that when the technician pulls the tray assembly 5 along the length direction, the main body 51 can slide smoothly on the tray frame 4.

[0074] According to embodiments of this application, such as Figure 2 As shown, the multiple sets of uprights 2 include two first uprights 21, two second uprights 22, and two third uprights 23. The two first uprights 21 are connected to the inner end of each bracket 3. The two second uprights 22 are arranged parallel to the two first uprights 21 at intervals along the length direction. The two third uprights 23 are arranged parallel to the two second uprights 22 at intervals along the length direction. The outer end of each bracket 3 passes through the two second uprights 22 along the length direction and extends out through the two third uprights 23, connecting to the outer end of the tray frame 4 to restrict the position of the bracket 3.

[0075] According to an embodiment of this application, multiple through holes 210 are provided on the two first columns 21 at intervals along the height direction. The multiple through holes 210 on one first column 21 are respectively aligned with the multiple through holes 210 on the other first column 21 in the width direction. The inner end of each bracket 3 can be connected to a set of through holes 210 aligned in the width direction on the two first columns 21 by snap-fit, so as to fix the bracket 3 on the two first columns 21.

[0076] According to an embodiment of this application, each tray 3 includes a second mounting portion 31 and two second support arms 32. The second mounting portion 31 is mounted on two first columns 21, which are configured to support the second mounting portion 31. The two second support arms 32 extend from the second mounting portion 31 along the length direction, pass through the two second columns 22 respectively, extend out from the two third columns 23, and are respectively connected to two operating members 43 to fix the tray frame 4.

[0077] According to embodiments of this application, such as Figure 2 As shown, the second mounting part 31 has two first protrusions 33 spaced apart in the width direction on the side opposite to the two second support arms 32. The two first protrusions 33 are respectively aligned with and inserted into the through holes 210 on the two first columns 21, so that the second mounting part 31 can be fixed on the two first columns 21.

[0078] According to an embodiment of this application, the outer end of each second support arm 32 protrudes along its length to form a second protrusion 320. Multiple second protrusions 320 may be provided on the outer end of each second support arm 32. Multiple mounting holes 430 are provided on each operating member 43, and these mounting holes 430 respectively engage with the multiple second protrusions 320 to fix the pallet frame 4 between the two second support arms 32. Simultaneously, after the multiple mounting holes 430 engage with the multiple second protrusions 320, the movement of the pallet frame 4 in the length direction can be restricted.

[0079] According to embodiments of this application, such as Figure 2 As shown, each of the two operating components 43 is provided with a handle, so that technicians can move the pallet frame 4 by using the two handles on the two operating components 43 to install the pallet frame 4 onto the bracket 3 or to remove the pallet frame 4 from the bracket 3 along the length direction.

[0080] According to an embodiment of this application, each second column 22 is provided with a plurality of through slots 220 to allow the second support arms 32 of the plurality of brackets 3 to pass through respectively. The server rack also includes a plurality of buffer devices 10. The plurality of buffer devices 10 are disposed between the second mounting part 31 and the second column 22, and between the second support arm 32 and the through slot 220, to provide buffering for movement between the brackets 3 and the second column 22.

[0081] According to an embodiment of this application, multiple through slots 220 are provided on the two second columns 22 at intervals along the height direction. Each through slot 220 extends along the height direction, and the multiple through slots 220 on one second column 22 are respectively aligned with the multiple through slots 220 on the other second column 22 in the width direction.

[0082] According to an embodiment of this application, multiple positioning grooves 230 are provided on the two third columns 23 at intervals along the height direction. Each positioning groove 230 extends along the height direction. The multiple positioning grooves 230 on one third column 23 are respectively aligned with the multiple positioning grooves 230 on the other third column 23 in the width direction. Furthermore, a set of positioning grooves 230 aligned in the width direction on the two third columns 23 are aligned with a set of through grooves 220 aligned in the width direction on the two second columns 22 in the length direction.

[0083] According to an embodiment of this application, the outer ends of the two second support arms 32 of each bracket 3 pass through a set of through slots 220 of the two second columns 22 and extend out through a set of positioning slots 230 of the two third columns 23, and are respectively connected to the two operating members 43 to fix the pallet frame 4 on the bracket 3. Further, the plurality of second protrusions 320 at the outer ends of the two second support arms 32 can be engaged with the plurality of mounting holes 430 of the two operating members 43, thereby fixing the pallet frame 4 to the two second support arms 32 of the bracket 3.

[0084] According to the embodiments of this application, the bracket 3 and the tray frame 4 are fixed in the receiving cavity of the server rack by multiple points of support from two first columns 21, two second columns 22 and two third columns 23, so as to ensure the overall stability of the server rack.

[0085] According to embodiments of this application, such as Figure 2 As shown, multiple buffer devices 10 can be installed on one side of the second mounting part 31 facing the two second support arms 32, and one end of each buffer device 10 is connected to the second mounting part 31, and the other end of each buffer device 10 is connected to the surface of the second column 22 facing the second mounting part 31.

[0086] According to an embodiment of this application, the buffer device 10 can also be installed between the second support arm 32 and the through groove 220, which can provide buffer for the movement between the bracket 3 and the second column 22 when the technician pulls the tray assembly 5 along the length direction, and reduce the vibration between the bracket 3 and the two second columns 22.

[0087] According to embodiments of this application, the buffer device 10 may be selected as an elastic element, specifically a spring.

[0088] According to an embodiment of this application, when installing the hard drive 11, the technician first needs to adjust the relative positions of the bracket 3 and the two second uprights 22, and place the tray frame 4 and tray assembly 5 on the bracket 3. The tray frame 4 is then pushed along its length, causing the first mounting portion 41 of the tray frame 4 to engage with the second mounting portion 31 of the bracket 3, while simultaneously inserting the first protrusion 33 on the second mounting portion 31 of the bracket 3 into the through holes 210 of the two first uprights 21. At this time, the two first uprights 21, the two second uprights 22, and the two third uprights 23 together provide support for the bracket 3, ensuring the stability of the tray frame 4 and tray assembly 5 on the bracket 3 within the server rack. The technician then pulls the tray assembly 5 out of the tray frame 4 along its length. When the main body 51 slides until the guide plate 520 of the hook 52 passes over the reversing wheel 53 and the reversing plate 521 abuts against the reversing wheel 53, the reversing wheel 53 guides the main body 51 from the first state to the second state. At this time, the hook 52 is located between the reversing wheel 53 and the gear 54. The gear 54 rotates under the drive of the hook 52. The moving rack 550 of the drive mechanism 55 meshes with the gear 54, so that while the guide plate 520 and the reversing plate 521 drive the gear 54 to rotate, it moves along the length direction toward the inner end of the mounting plate 440. When the moving rack 550 moves toward the inner end of the mounting plate 440, the drive part 551 of the drive mechanism 55 drives the lighting device 6 to rotate and triggers the lighting device 6 to emit light. The main body 51 is finally attracted and fixed by the magnetic suction member 7. At this time, the main body 51 is in the second state where it is suspended from the outer end of the tray frame 4 in the height direction. It occupies less space in the length direction. And because the lighting device 6 illuminates the surface of the main body 51 in the height direction, technicians can easily install the hard drive 11 on the main body 51 and store the cable after passing it through the cable tray 9. After the technicians complete the installation of the hard drive 11, they can reset the main body 51. In deployment scenarios with limited depth or against a wall, technicians can plug and unplug hard drives 11 without reserving operating space in front of the server rack, significantly improving the deployment adaptability and maintenance convenience of small server rack environments, breaking through space limitations and improving operational flexibility.

[0089] According to the embodiments of this application, the plug-in installation structure of the bracket 3 and the two second columns 22, combined with the precise guidance of the two third columns 23, greatly shortens the installation time of the single-layer bracket mechanism and the tray assembly 5. It also cleverly integrates functions such as sliding, flipping, locking, lighting, and wiring into the tray assembly 5. The linkage design of the hook 52, the reversing wheel 53, the gear 54, and the drive mechanism 55 realizes the automated coordinated action of the main body 51 moving, the lighting device 6 rotating and locking. The structure inside the server rack is compact and efficient, taking into account both functionality and space efficiency.
