Description

Technical Field

[0001] The present invention relates to the technical field of server hard disk brackets, in particular to a server hard disk bracket. Background Art

[0002] With the rapid development of information technology, the demand for data storage has exploded. As core equipment for data storage and processing, the installation, management, and maintenance of hard drives within servers have become crucial. The performance of hard drive trays, crucial components for carrying and securing hard drives, directly impacts server stability and maintainability. During ESD immunity testing of servers equipped with hard drives, static electricity is applied to the hard drives to verify their resistance to static electricity (ESD) and meet professional standards. Because the hard drive and server are connected via the hard drive tray, the design of the hard drive tray's grounding and charge dissipation is particularly critical.

[0003] Traditional hard drive trays are often large, limiting the number of hard drives that can be installed within a server. Furthermore, their single size makes it difficult to accommodate hard drives of varying models and sizes, requiring the replacement of different tray types during installation, increasing costs. Hard drives contain complex mechanical structures and electronic components, which generate high temperatures over extended periods of operation. This high temperature increases the resistance of the hard drive's internal circuitry, causing signal transmission delays. When the server receives a read or write command, the hard drive takes longer to process and respond, increasing the response time of the entire system and impacting the server's overall performance.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-13The present invention provides a technical solution: a server hard disk bracket, comprising a mounting frame 1, conductive sheets 2 are installed on both sides and the top of the mounting frame 1, a movable frame 3 is limited and slidable inside the mounting frame 1, a clamping platform 4 is limited and slidable on the inner side of the inner wall of the movable frame 3, a bidirectional screw rod 6 is installed at the bottom of the movable frame 3, an adjustment plate 7 is installed at the bottom of the clamping platform 4, a screw rod 9 and a slide platform 10 are installed at the bottom of the movable frame 3, a ventilation pipe 11 is provided on the movable frame 3, a resistance pipe 12 is limited and slidable inside the ventilation pipe 11, a locking and pop-up mechanism is installed inside the mounting frame 1, a temperature sensor 14 is installed inside the mounting frame 1, and a temperature reduction adjustment component is installed inside the ventilation pipe 11;

[0036] The locking and pop-up mechanism includes a mounting plate 151 installed at the end of the movable frame 3, a limit block 152 is installed at the end of the mounting plate 151, a convex plate 153 is installed on the inner side wall of the mounting frame 1, a hook plate 154 is rotatably connected to the inner side wall of the mounting frame 1, and a first electric push rod 155 is installed at the bottom end of the inner part of the mounting frame 1.

[0037] In one embodiment of the present invention, the conductive sheet 2 is a thin sheet made of stainless steel, and the number of clamping platforms 4 is two groups. The two groups of clamping platforms 4 are symmetrically distributed at both ends of the interior of the mobile frame 3. When the hard disk is subject to external static electricity interference, the charge can be quickly discharged through the hard disk bracket spring, so that the hard disk function on the server can still operate stably and normally under static electricity interference.

[0038] As an embodiment of the present invention, a contact plate 5 is provided inside the clamping platform 4 for limiting sliding. A spring is installed at one end of the contact plate 5 close to the clamping platform 4, and the other end of the spring is connected to the inner wall of the clamping platform 4. The adjustment plate 7 is limited and slides in the sliding groove at the bottom end of the movable frame 3. The bottom of the adjustment plate 7 is threadedly connected to the bidirectional screw 6. The contact plate 5 inside the clamping platform 4 can play a buffering role for the hard disk.

[0039] As an embodiment of the present invention, the surface of the contact plate 5 is provided with heat dissipation holes, which can cool the side ends of the hard plate. The bottom end of the mobile frame 3 is provided with a heat dissipation groove, and the bottom end of the mobile frame 3 is installed with a heat dissipation fan 8. A hose is connected between the heat dissipation fan 8 and the ventilation pipe 11. The airflow generated by the heat dissipation fan 8 can enter the ventilation pipe 11 through the hose, thereby dissipating the heat absorbed by the surface of the ventilation pipe 11.

[0040] As an embodiment of the present invention, the side end of the ventilation pipe 11 is threadedly connected to the screw 9, and the side end of the conflicting pipe 12 is limited and slides on the surface of the slide 10. There are three sets of ventilation pipes 11 and conflicting pipes 12. The bottom of the ventilation pipes 11 and conflicting pipes 12 are both provided with air outlets. The ventilation pipes 11 and conflicting pipes 12 are made of brass. The brass ventilation pipe 11 can absorb the heat generated in the hard disk. The establishment of the three sets of ventilation pipes 11 can improve the cooling effect of the hard disk.

[0041] As an embodiment of the present invention, a spring is installed at the top of the protruding plate 153, and the other end of the spring is connected to the bottom end of the hook plate 154. The limit block 152 is an "L"-shaped block, and the hook plate 154 has an inclined surface at one end close to the movable frame 3. A spring is installed inside the mounting frame 1, and the other end of the spring is connected to the mounting plate 151. When the limit block 152 loses the limit of the hook plate 154, the rebound force of the spring will pop the movable frame 3 out of the mounting frame 1.

[0042] When the hard disk bracket is not convenient for adapting to hard disks of different models and sizes, the hard disk has complex mechanical structures and electronic components inside, which will generate high temperature after long-term operation. High temperature will increase the resistance of the internal circuit of the hard disk, causing signal transmission delay. The specific implementation method is as follows: when working, first place the hard disk inside the mobile rack 3, and then rotate the bidirectional screw 6. At this time, the adjustment plate 7 slides in the slide groove at the bottom end of the mobile rack 3, so that the adjustment plate 7 drives the clamping platform 4 to move toward the center inside the mobile rack 3. At this time, the clamping platform 4 drives the contact plate 5 to clamp the hard disk. When the clamping platform 4 moves, the adjustment plate 7 will squeeze the first piston rod 132, and the oil on the inner wall of the second oil tank 133 will be transported to the second oil tank 1 33, at this time, the oil inside the second oil tank 133 increases, pulling the second piston rod 134 to recover, and the recovery of the second piston rod 134 drives the connecting bar 135 to recover together. At this time, the distance between the teeth on the surface of the connecting bar 135 and the closing plate 137 increases, and then the mounting rack 1 is inserted into the server. The heat generated by the hard disk when working is absorbed by the ventilation pipe 11 through the heat dissipation groove at the bottom of the movable rack 3. At this time, the controller drives the cooling fan 8 to work, and the air flow generated by the cooling fan 8 enters the ventilation pipe 11 through the hose, and is then discharged through the air outlet at the bottom of the friction pipe 12. Then, the screw 9 is driven by the controller to rotate back and forth, so that the screw 9 drives the ventilation pipe 11 and the friction pipe 12 to move at the bottom end of the movable rack 3;

[0043] As an embodiment of the present invention, the temperature-cooling regulating assembly includes a first oil tank 131 installed at the bottom end of the movable frame 3, a first piston rod 132 is limited and slidably provided inside the first oil tank 131, and the extended end of the first piston rod 132 is connected to the side end of the regulating plate 7, and further includes a second oil tank 133 installed inside the contact tube 12, a second piston rod 134 is limited and slidably provided inside the second oil tank 133, and a connecting strip 135 is installed at the extended end of the second piston rod 134, a vent hole is opened inside the vent pipe 11, a mounting ring 136 is installed around the vent hole inside the vent pipe 11, a closing plate 137 is limited and slidably provided inside the mounting ring 136, and a gear ring 138 is rotatably connected to the surface of the mounting ring 136. The design of the temperature-cooling regulating assembly can continuously cool the hard disk, ensure that the hard disk operates in a stable temperature environment, and improve the stability and reliability of the hard disk;

[0044] As an embodiment of the present invention, a hose is connected between the first oil tank 131 and the second oil tank 133, and teeth are installed on the surface of the connecting strip 135. The teeth on the surface of the connecting strip 135 are engaged with the connecting strip 135, and a limiting groove is provided on the surface of the gear ring 138. The protrusion on the surface of the closing plate 137 slides in the limiting groove on the surface of the gear ring 138. The slide 10 slides within the limit at the bottom end of the movable frame 3, and a second electric push rod 156 is installed at the bottom end of the movable frame 3. The protruding end of the second electric push rod 156 is connected to the side end of the slide 10. The wind force can be adjusted according to the specifications of the hard disk. Wind cooling can quickly reduce the temperature of the hard disk and reduce the damage of high temperature to the electronic components inside the hard disk.

[0045] Working principle: When working, first place the hard disk inside the mobile rack 3, then rotate the bidirectional screw 6, at this time the adjustment plate 7 slides in the slide groove at the bottom end of the mobile rack 3, so that the adjustment plate 7 drives the clamping platform 4 to move toward the center inside the mobile rack 3, at this time the clamping platform 4 drives the contact plate 5 to clamp the hard disk, when the clamping platform 4 moves, the adjustment plate 7 will squeeze the first piston rod 132, and transport the oil on the inner wall of the second oil tank 133 to the second oil tank 133, at this time the oil inside the second oil tank 133 increases, pulling the second piston rod 134 to recover, and the second piston rod 134 The recovery drives the connecting strip 135 to be recovered together. At this time, the distance between the teeth on the surface of the connecting strip 135 and the closing plate 137 increases. Then, the mounting rack 1 is inserted into the server. The heat generated by the hard disk during operation is absorbed by the ventilation pipe 11 through the heat dissipation groove at the bottom of the movable rack 3. At this time, the controller drives the cooling fan 8 to work. The airflow generated by the cooling fan 8 enters the ventilation pipe 11 through the hose and is discharged through the air outlet at the bottom of the friction pipe 12. Then, the controller drives the screw 9 to rotate back and forth, so that the screw 9 drives the ventilation pipe 11 and the friction pipe 12 to move at the bottom end of the movable rack 3.

[0046] When the temperature sensor 14 detects that the temperature inside the mounting rack 1 is gradually rising and difficult to drop, the controller drives the extended end of the first electric push rod 155 to extend and contact the bottom of the hook plate 154, causing it to rotate inside the inner side wall of the mounting rack 1, so that the hook plate 154 loses its limit on the limit block 152. Since the spring between the mounting plate 151 and the mounting rack 1 is in a compressed state, after the limit block 152 loses its limit, it receives the rebound of the spring and slides the mobile rack 3 out of the mounting rack 1. When the pop-up operation is executed, the system will first send a command to the hard disk to ensure that all ongoing read and write operations are completed and the data in the cache is written to the hard disk. When the mobile rack 3 slides and pops out inside the mounting rack 1, the controller drives the extended end of the second electric push rod 156 to return The extended end of the second electric push rod 156 is recovered to drive the slide 10 to move toward the center of the movable frame 3. When the slide 10 moves, it drives the resistance tube 12 to slide toward the inside of the vent pipe 11, so that the air outlet at the bottom of the resistance tube 12 is closed. When the resistance tube 12 moves, it pushes the second oil tank 133 and the second piston rod 134 to move together. The second piston rod 134 drives the connecting bar 135 to move in the vent pipe 11. At this time, the teeth on the surface of the connecting bar 135 drive the gear ring 138 to rotate at the bottom of the mounting ring 136. The rotation of the gear ring 138 drives the connecting bar 135 to slide to both sides inside the mounting ring 136, thereby opening the vent hole at the top of the vent pipe 11. At this time, the airflow of the cooling fan 8 can be discharged through the vent hole at the top of the vent pipe 11, continuously cooling the hard disk.
