Description

Technical Field

[0001] The present invention relates to the field of hard disk installation, and in particular to a hard disk installation device, electronic equipment and a hard disk vibration reduction method. Background Art

[0002] Electronic devices, such as servers, often use large-capacity mechanical hard disk drives (HDDs) to read and write large amounts of data. The motor inside a HDD drives the platters to rotate at high speeds, enabling data reading and writing. Due to the mechanical structure of the motor, some vibration is inevitably generated during operation. This is particularly noticeable during the drive's startup and shutdown phases, where the motor's acceleration and deceleration can cause significant vibration. Furthermore, when reading and writing data, the hard disk's magnetic head moves rapidly across the platter surface to locate the data. This frequent movement of the magnetic head generates minute impact forces, which accumulate and cause vibration throughout the drive. Furthermore, during the data reading and writing process, the hard disk's electronic and mechanical components operate at high speeds, resulting in energy loss, some of which is released as heat.

[0003] In the related technology, mechanical hard disks are generally subjected to vibration reduction by rubber pads or fixed brackets. When the vibration is more severe, the precision components inside the hard disk (such as the disk and the head) are easily damaged by collision, resulting in data loss. In addition, the heat dissipation efficiency of the heat sink is low, and when the hard disk temperature is too high, it will not only reduce the reading and writing performance, but may also cause data errors and even lead to hard disk hardware failure. The maintenance and protection of mechanical hard disks mostly rely on manual operations, which are inefficient and slow to respond. They cannot respond to sudden vibrations and temperature changes in time and are prone to errors.

[0004] Therefore, how to improve the reliability of the hard disk installation device is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0005] The purpose of the present invention is to provide a hard disk installation device, an electronic device and a hard disk vibration reduction method, which can effectively reduce the vibration of the hard disk body and extend the service life of the hard disk body.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A hard disk installation device, comprising:

[0008] The housing has a cavity therein for the hard disk body to be placed;

[0009] A support and anti-vibration assembly is installed in the housing, the support and anti-vibration assembly includes symmetrically arranged support rods and a plurality of clamping plate assemblies arranged on the support rods, the clamping plate assemblies are used to clamp or release the two sides of the hard disk body;

[0010] A drive assembly includes symmetrically arranged moving plates, synchronous driving members connected to two adjacent moving plates, and a power component for driving the synchronous driving members to move, wherein the moving plates are connected to the support rods in a one-to-one correspondence, and the synchronous driving members are used to drive the two adjacent moving plates to move closer to or away from each other;

[0011] a vibration sensor, mounted on the clamping plate assembly, for acquiring vibration of the clamping plate assembly;

[0012] A controller is connected to the power component and the vibration sensor respectively, and the controller is used to control the action of the power component according to the vibration of the clamping plate assembly.

[0013] The present invention also provides an electronic device comprising any one of the hard disk mounting devices described above.

[0014] A hard disk vibration reduction method, applied to the above-mentioned hard disk installation device, comprises the following steps:

[0015] After obtaining that the hard disk body is installed in the cavity, controlling the power component to move the two adjacent movable plates to the target position;

[0016] Acquiring the vibration frequency of the splint assembly in real time through the vibration sensor;

[0017] When the vibration frequency of the clamping plate assembly is greater than or equal to the first preset frequency, the power component is controlled to move to drive two adjacent movable plates to approach each other;

[0018] When the vibration frequency of the clamping plate assembly is less than or equal to a second preset frequency, the power component is controlled to move to drive two adjacent movable plates to move away from each other, and the second preset frequency is less than the first preset frequency.

[0019] The hard disk installation device provided by the present invention has the following beneficial effects: the hard disk body is placed in the cavity of the shell by setting the shell, and an opening is also provided on one side of the shell for the hard disk body to be inserted into the cavity; by setting the support and vibration-proof component, the hard disk body is fixed and at the same time, a vibration-reducing effect is achieved. Specifically, the support and vibration-proof component includes a support rod and a plurality of clamping plate assemblies. The clamping plate assembly is arranged on the support rod, and the clamping plate assembly can move with the support rod. The extension direction of the support rod is consistent with the installation direction of the hard disk body. When the two support rods approach or move away from each other, the clamping plate assembly will be driven to clamp or release the hard disk body; by setting the driving assembly, the moving direction of the support rod can be automatically controlled. Specifically, when the power component drives the synchronous driving component to move, the synchronous driving component will drive the two adjacent moving plates to approach or move away from each other. The movable plate is installed on the support rod. When the movable plate moves, it will drive the support rod to move synchronously, and the support rod will drive the clamping plate assembly to move, thereby clamping or releasing the hard disk body. Then, a vibration sensor is installed on the clamping plate assembly, and the vibration of the clamping plate assembly is obtained as a judgment basis. The power component is controlled by the controller. When the clamping plate assembly vibrates, it means that the clamping of the hard disk body is too loose. By driving the power component, the two adjacent movable plates are brought closer to each other. When the clamping plate assembly no longer vibrates, or the vibration frequency of the clamping plate assembly is reduced to a certain level, it means that the clamping of the hard disk body does not need to be too tight. At this time, the power component can be driven in the opposite direction to make the two adjacent movable plates move away from each other, thereby avoiding the clamping of the hard disk body by the clamping plate assembly being too tight, resulting in hard disk body failure.

[0020] The hard disk installation device provided by the present invention can effectively reduce the vibration of the hard disk body by supporting the setting of the anti-vibration component. At the same time, through the setting of the vibration sensor and the controller, it can realize automatic adjustment of the clamping tightness of the hard disk body, thereby protecting the stable operation of the hard disk body, ensuring the accurate reading and writing of data in the hard disk body during the production process, saving labor costs, avoiding the risk of damage to the hard disk body due to untimely or inaccurate manual operation, effectively extending the service life of the hard disk body, and ensuring data security.

[0021] In one embodiment, it further includes a heat-conducting component, an air-collecting shell, and a heat-dissipating fan. The air-collecting shell is installed at the top and / or bottom of the shell, and the heat-dissipating fan is located at the air outlet of the air-collecting shell. The heat-conducting component extends from the cavity to the inside of the air-collecting shell, and after the hard disk body is placed in the cavity, the heat-conducting component abuts against the upper surface and / or lower surface of the hard disk body. The above arrangement, by providing a heat-conducting component, can conduct the heat of the hard disk body to the air-collecting shell, and then extract the gas in the air-collecting shell through the heat-dissipating fan, which can effectively improve the heat dissipation efficiency; at the same time, the heat-conducting component is abutted against the upper surface and / or lower surface of the hard disk body, which can play a role of pre-positioning after the hard disk body is installed in the cavity, making it convenient for the subsequent clamping plate component to clamp and fix the side of the hard disk body, and facilitating the disassembly and assembly of the hard disk body.

[0022] The electronic device provided by the present invention is provided with the above-mentioned hard disk installation device. Since the hard disk installation device has the above-mentioned technical effects, the electronic device provided with the hard disk installation device should also have corresponding technical effects.

[0023] The hard disk vibration reduction method provided by the present invention obtains the vibration frequency of the clamping plate assembly in real time through the vibration sensor, and when the vibration frequency of the clamping plate assembly is ≥ a first preset frequency, controls the clamping plate assembly to clamp the hard disk body to slow down the vibration of the hard disk body, and when the vibration frequency of the clamping plate assembly is ≤ a second preset frequency, controls the clamping plate assembly to reduce the clamping force on the hard disk body to prevent excessive squeezing of the hard disk body, avoid deformation of the hard disk body shell or internal structure due to long-term excessive squeezing, affect the normal operation of the hard disk body, and extend the service life of the hard disk body.

[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 8 In this embodiment, the hard disk installation device includes:

[0039] The housing 1 has a cavity therein for the hard disk body 24 to be placed;

[0040] The support and anti-vibration assembly is installed in the housing 1. The support and anti-vibration assembly includes symmetrically arranged support rods 16 and a plurality of clamping plate assemblies arranged on the support rods 16. The clamping plate assemblies are used to clamp or release the two sides of the hard disk body 24;

[0041] The drive assembly includes symmetrically arranged moving plates 15, synchronous drive members 26 connected to two adjacent moving plates 15, and a power component 27 for driving the synchronous drive members 26. The moving plates 15 are connected to the support rods 16 in a one-to-one correspondence. The synchronous drive members 26 are used to drive the two adjacent moving plates 15 toward or away from each other.

[0042] a vibration sensor 28 mounted on the clamping plate assembly for detecting vibration of the clamping plate assembly;

[0043] The controller is connected to the power component 27 and the vibration sensor 28 respectively. The controller is used to control the action of the power component 27 according to the vibration of the splint assembly. Specifically, the vibration frequency of the splint assembly can be obtained through the vibration sensor 28, and the magnitude of the vibration frequency can be used as a basis for judgment.

[0044] Specifically, the shell 1 can be a plastic shell 1 or a metal shell 1. The hard disk mounting device can be used in electronic equipment, such as a server. The fixed support of the anti-vibration component for the hard disk body 24 is achieved by the left and right sides of the hard disk body 24; the driving component is to realize the driving of the support rod 16, and the synchronous driving member 26 can be a double-headed screw, or the synchronous driving member 26 can also be a telescopic rod, which can pull or push the two movable plates 15 closer to or away from each other; the movable plate 15 is connected to the support rod 16; further, the thickness of the position where the movable plate 15 is connected to the support rod 16 is greater than the middle thickness of the movable plate 15, and the thickness of the position where the movable plate 15 is connected to the synchronous driving member 26 is also greater than the middle thickness of the movable plate 15, such as Figure 8 As shown, such an arrangement can reduce the material used for the moving plate 15 and reduce the weight, while also ensuring the connection stability between the moving plate 15 and the support rod 16, and between the moving plate 15 and the synchronous drive member 26.

[0045] The hard disk installation device places the hard disk body 24 into the cavity of the shell 1 through the setting of the shell 1. One side of the shell 1 is also provided with an opening for the hard disk body 24 to be inserted into the cavity; by setting a support and vibration-proof component, the hard disk body 24 is fixed and at the same time, a vibration-reducing effect is achieved. Specifically, the support and vibration-proof component includes a support rod 16 and a plurality of clamping plate assemblies. The clamping plate assembly is arranged on the support rod 16. The clamping plate assembly can move with the support rod 16. The extension direction of the support rod 16 is consistent with the installation direction of the hard disk body 24. When the two support rods 16 approach or move away from each other, the clamping plate assembly will be driven to clamp or release the hard disk body 24; by setting a driving assembly, automatic control of the moving direction of the support rod 16 is achieved. Specifically, when the power component 27 drives the synchronous driving member 26 to move, the synchronous driving member 26 will drive the two adjacent moving plates 15 to approach or move away from each other, and the moving The plate 15 is installed on the support rod 16. When the movable plate 15 moves, it will drive the support rod 16 to move synchronously, and the support rod 16 drives the clamping plate assembly to move, thereby clamping or releasing the hard disk body 24; then, by installing the vibration sensor 28 on the clamping plate assembly, the vibration of the clamping plate assembly is obtained as the basis for judgment, and the power component 27 is controlled by the controller. When the clamping plate assembly vibrates, it means that the clamping of the hard disk body 24 is too loose. By driving the power component 27, the two adjacent movable plates 15 can be brought close to each other. When the clamping plate assembly no longer vibrates, or the vibration frequency of the clamping plate assembly is reduced to a certain level, it means that the clamping of the hard disk body 24 does not need to be too tight. At this time, the power component 27 can be driven in the opposite direction to make the two adjacent movable plates 15 move away from each other, thereby avoiding the clamping of the hard disk body 24 by the clamping plate assembly being too tight, causing the hard disk body 24 to malfunction.

[0046] The hard disk installation device can effectively reduce the impact of vibration on the hard disk body 24 by supporting the setting of the anti-vibration component. At the same time, through the setting of the vibration sensor 28 and the controller, it can realize automatic adjustment of the clamping tightness of the hard disk body 24, thereby protecting the stable operation of the hard disk body 24, ensuring the accurate reading and writing of data in the hard disk body 24 during the production process, saving labor costs, avoiding the risk of damage to the hard disk body 24 due to untimely or inaccurate manual operation, effectively extending the service life of the hard disk body 24, and ensuring data security.

[0047] In some embodiments, as Figure 8As shown, the splint assembly includes a splint body 23, a first sliding frame 19-1 and a second sliding frame 19-2, the first sliding frame 19-1 and the second sliding frame 19-2 are both sleeved on the support rod 16, and a partition 17 is also provided on the support rod 16, the first sliding frame 19-1 and the second sliding frame 19-2 are respectively located on both sides of the partition 17, and a first elastic component 18 is provided between the first sliding frame 19-1 and the partition 17, and between the second sliding frame 19-2 and the partition 17, the splint body 23 and the first sliding frame 19-1, and between the splint body 23 and the second sliding frame 19-2 are hinged through a linkage plate 21; specifically, the first sliding frame 19-1 and the second sliding frame 19-2 can slide freely on the support rod 16, and the first sliding frame 19- 1 and the position of the second sliding frame 19-2 are limited by the first elastic component 18, the first elastic component 18 can be a tension spring, and the two ends of the first elastic component 18 are respectively connected to the partition 17 and the first sliding frame 19-1, or the two ends of the first elastic component 18 are respectively connected to the partition 17 and the second sliding frame 19-2; the first sliding frame 19-1 and the second sliding frame 19-2 are both provided with a first rotating block 20, and the splint body 23 is provided with two second rotating blocks 22, and the two ends of the linkage plate 21 are respectively connected to the first rotating block 20 and the second rotating block 22; the number of splint assemblies can be four, and each support rod 16 is provided with two splint assemblies, and the four splint assemblies respectively fix the four corners of the hard disk body 24 to ensure the stability of the hard disk body 24.

[0048] Furthermore, when the support rods 16 approach each other, the pressure between the splint body 23 and the hard disk body 24 increases, and the hard disk body 24 pushes the splint body 23 to move toward the support rod 16. During the movement of the splint body 23, the linkage plate 21 is pushed to swing in the opposite direction. The linkage plate 21 pushes the first sliding frame 19-1 and the second sliding frame 19-2 away from each other. Under the action of the first elastic component 18, a pulling force is provided to the first sliding frame 19-1 and the second sliding frame 19-2 until the pulling force of the first sliding frame 19-1 and the second sliding frame 19-2 are equal to the pushing force and remain stable.

[0049] In some embodiments, at least one clamping plate assembly is arranged at both ends of each support rod 16, and a recess is provided on the clamping plate body 23, which is used to abut against the edge of the hard disk body 24; specifically, a recess is provided on the clamping plate body 23, and the upper and lower sides of the recess are provided with inclined surfaces for quickly positioning with the edge of the hard disk body 24; of course, the position in the recess for abutting against the edge of the hard disk body 24 should be flat to ensure stable clamping with the hard disk body 24.

[0050] In some embodiments, the movable plate 15 is sleeved on the middle part of the support rod 16, the synchronous drive member 26 is a bidirectional screw, and the two ends of the synchronous drive member 26 are respectively threadedly connected to a corresponding movable plate 15, and the power component 27 is used to drive the synchronous drive member 26 to rotate forward or reverse to drive the two movable plates 15 to move closer to or away from each other; specifically, the movable plate 15 is sleeved on the middle part of the support rod 16, which can ensure that the movable plate 15 drives the support rod 16 to move more smoothly, and the movable plate 15 and the support rod 16 can be fixedly connected; through the setting of the bidirectional screw, the bidirectional screw can be set with threads at the positions corresponding to the movable plate 15 at both ends.

[0051] In some embodiments, as Figure 7 As shown, the drive assembly also includes a plurality of support seats 25, which are fixed on the shell 1, and the two ends of the synchronous drive member 26 are respectively hinged to a support seat 25, and the power component 27 is arranged on the support seat 25; specifically, the setting of the support seat 25 can provide good support for the two ends of the synchronous drive member 26, ensure the stable installation of the synchronous drive member 26, and thus ensure the stable driving of the movable plate 15; the support seat 25 can be integrally formed with the shell 1, or fixed inside the shell 1 by welding or the like; the power component 27 is installed on the support seat 25, thereby ensuring the stability of the power component 27.

[0052] In some embodiments, as Figure 1 and Figure 2 As shown, it also includes an extrusion frame 2 symmetrically arranged on both sides of the shell 1, and a buffer pad 4 is also provided on both sides of the shell 1, one end of the extrusion frame 2 is connected to the shell 1, and the other end is suspended and inclined in the direction away from the shell 1; a dial plate 3 is also provided at the suspended end of the extrusion frame 2, which is used to press the extrusion frame 2 in the direction close to the shell 1; specifically, the buffer pad 4 can be a rubber block; specifically, the outer wall of the shell 1 is fixedly connected with the symmetrically distributed extrusion frame 2, and the inner part of the extrusion frame 2 is against the outer wall of the rubber block, and the end of the extrusion frame 2 away from the shell 1 is fixedly connected with the dial plate 3; when the shell 1 is installed to the electronic device, the extrusion frame 2 will shrink in the direction close to the shell 1 until the extrusion frame 2 is pressed against the rubber block, and the reaction force of the rubber block fixes the extrusion frame 2 to the electronic device, thereby facilitating the fixing of the shell 1; when the shell 1 and the electronic device need to be disassembled, it is only necessary to drive the dial plate 3 to move in the direction close to the shell 1, thereby pressing the extrusion frame 2, and the pressure between the extrusion frame 2 and the electronic device is reduced, and the shell 1 can be removed from the electronic device, which is easy to operate.

[0053] In some embodiments, as Figure 5As shown, the drive assembly also includes a number of limiting heat-conducting rods 14-1, which are fixed in the shell 1, and the movable plate 15 is sleeved on the limiting heat-conducting rods 14-1; the extension direction of the support rod 16 is parallel to the installation direction of the hard disk body 24, and the extension direction of the limiting heat-conducting rod 14-1 is parallel to the extension direction of the synchronous drive member 26. Specifically, the limiting heat-conducting rod 14-1 can be selected as the limiting heat-conducting rod 14-1, which saves materials, reduces weight, and is conducive to transferring heat to the shell 1; further, the two ends of the limiting heat-conducting rod 14-1 are respectively fixed in the shell 1, and the number of limiting heat-conducting rods 14-1 can be at least two. The limiting heat-conducting rod 14-1 is located on both sides of the synchronous drive member 26, and the movable plate 15 can slide relative to the limiting heat-conducting rod 14-1. The limiting heat-conducting rod 14-1 plays the role of limiting the movable plate 15 on the one hand, and plays the role of heat conduction on the other hand, which can transfer the heat in the internal cavity of the shell 1 to the shell 1, and the heat of the shell 1 can be dissipated through the cooling fan 6.

[0054] In some embodiments, an in-place sensor is also included. The in-place sensor is installed in the cavity of the shell 1 and is used to obtain the installation status of the hard disk body 24. The in-place sensor is connected to the controller. When the in-place sensor detects that the hard disk body 24 is installed in place, it will send an installation in-place signal to the controller. After receiving the installation in-place signal, the controller will control the power component 27 to start. The power component 27 can move the clamping plate assembly to the target position according to the size and model of the hard disk body 24, so as to fix the hard disk body 24; of course, other methods can also be used to determine whether the hard disk body 24 is clamped. For example, the sliding distance between the first sliding frame 19-1 and the second sliding frame 19-2 can be determined to determine whether the clamping plate assembly clamps the hard disk body 24.

[0055] In some embodiments, as Figure 6 As shown, a heat conducting component is also included. The heat conducting component extends from the cavity to the interior of the air collecting housing 5. After the hard disk body 24 is placed in the cavity, the heat conducting component abuts the upper surface and / or lower surface of the hard disk body 24. The above arrangement, by providing the heat conducting component, can conduct the heat of the hard disk body 24 into the air collecting housing 5. At the same time, the heat conducting component abuts the upper surface and / or lower surface of the hard disk body 24, which can play a role in pre-positioning after the hard disk body 24 is installed in the cavity, making it easier for the subsequent clamping plate assembly to clamp and fix the side of the hard disk body 24, and facilitating the installation and removal of the hard disk body 24.

[0056] In some embodiments, an air collecting shell 5 and a heat dissipation fan 6 are further included. The air collecting shell 5 is installed at the top and / or bottom of the housing 1, and the heat dissipation fan 6 is located at the air outlet of the air collecting shell 5. After the heat dissipation component transfers the heat of the hard disk body 24 to the air collecting shell 5, the gas in the air collecting shell 5 is extracted through the heat dissipation fan 6, which can effectively improve the heat dissipation efficiency. Specifically, the air in the air collecting shell 5 is provided by the housing 1, and then discharged from the air outlet through the heat dissipation fan 6. Furthermore, in order to improve the heat dissipation efficiency, an air collecting shell 5 can be provided at the top and bottom of the housing 1, and a heat dissipation component can be correspondingly provided at the top and bottom of the cavity, so that the heat of the hard disk body 24 can be transferred to the corresponding air collecting shell 5 from the upper and lower directions respectively. A plurality of heat dissipation fans 6 are installed on each air collecting shell 5 to further improve the heat dissipation effect.

[0057] In some embodiments, the surface of the air collecting shell 5 is inclined from near the air outlet to away from the air outlet, toward the side close to the shell 1. In this way, the gas inside the air collecting shell 5 is drawn out by the heat dissipation fan 6, thereby increasing the air flow rate inside the air collecting shell 5.

[0058] In some embodiments, as Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the heat-conducting assembly includes a heat-conducting sheet 13, a heat sink 7 and several heat-conducting components. The heat-conducting sheet 13 is located in the cavity, the heat sink 7 is arranged in the air collecting shell 5, and the heat-conducting assembly is connected between the heat-conducting sheet 13 and the heat sink 7. The extension direction of the heat sink 7 is perpendicular to the extension direction of the heat-conducting sheet 13. The heat-conducting assembly is used to transfer the heat of the hard disk body 24 to the heat sink 7. Furthermore, the thermal conductive sheet 13 includes a first thermal conductive sheet and a second thermal conductive sheet, a plurality of first thermal conductive components are connected to the first thermal conductive sheet, a plurality of second thermal conductive components are connected to the second thermal conductive sheet, the positions of the first thermal conductive components on the first thermal conductive sheet correspond one to one with the positions of the second thermal conductive components on the second thermal conductive sheet, and the heat sink 7 is connected between the first thermal conductive component and the second thermal conductive component; the number of the first thermal conductive component and the second thermal conductive component and the number of the heat sink 7 are the same, that is, the number of the thermal conductive sheets 13 can be two, the number of the first thermal conductive component and the second thermal conductive component and the number of the heat sink 7 can be more than three. This arrangement is to ensure that the heat of the thermal conductive sheet 13 can be transferred to the heat sink 7 more quickly, thereby further improving the heat dissipation efficiency.

The second rotating block 22 is rotatably connected to the splint body 23, and the two symmetrical splint bodies 23 A hard disk body 24 is arranged between them, and a vibration sensor 28 is fixedly connected to at least one clamping plate body 23. When the hard disk body 24 is in use, the vibration sensor 28 located on the clamping plate body 23 monitors the vibration of the hard disk body 24 in real time. When vibration is detected, a signal is transmitted, and the power component 27 is started after receiving the signal from the vibration sensor 28, and rotates forward or reverse according to the received signal, thereby driving the synchronous driving component 26 to rotate forward or reverse, so as to facilitate the adjustment of the clamping degree of the clamping plate body 23, so that the clamping force of the clamping plate body 23 on the hard disk body 24 changes; specifically, under high vibration frequency, the hard disk body 24 is more likely to be displaced, and at this time it can be By increasing the clamping force, the hard disk body 24 can be firmly fixed to prevent it from shaking in the shell 1, and the collision between the magnetic head inside the hard disk body 24 and the disk and other components can be avoided, thereby reducing the risk of physical damage caused by collision and protecting the integrity of data storage; when the vibration frequency is reduced to a reasonable range, the clamping force can be appropriately reduced to prevent excessive squeezing of the hard disk body 24, and to avoid deformation of the hard disk body 24 shell or internal structure due to long-term excessive squeezing, affecting the normal operation of the hard disk body 24, and extending the service life of the hard disk body 24. The first elastic component 18 plays a role in absorbing impact force in this process, absorbing and dispersing vibration energy, and reducing the impact of vibration on the hard disk body 24.

[0062] Furthermore, the drive assembly is arranged in the shell 1, and the drive assembly cooperates with the support and vibration isolation assembly; the drive assembly includes a power component 27 fixedly connected to the shell 1, the power component 27 is a driving motor, the output end of the power component 27 is fixedly connected to the synchronous drive component 26, and the synchronous drive component 26 is threadedly connected to the movable plate 15, and the end of the synchronous drive component 26 away from the output end of the power component 27 is rotatably connected to the support base 25, and the support base 25 is fixedly connected to the shell 1, and the synchronous drive component 26 is driven to rotate by the output end of the power component 27.

[0063] Furthermore, the heat-conducting assembly includes a fixed heat-conducting rod 8 symmetrically fixedly connected to the shell 1, and the outer wall of the fixed heat-conducting rod 8 is slidably connected to a sliding heat-conducting tube 14-2, and the end of the sliding heat-conducting tube 14-2 away from the fixed heat-conducting rod 8 is fixedly connected to a heat-conducting plate 13, and the outer wall of the heat-conducting plate 13 is against the surface of the hard disk body 24, and the sliding heat-conducting tube 14-2 is fixedly connected to a bottom limit ring 12, a hollow telescopic heat-insulating tube 9 is fixedly connected to the shell 1, and the hollow telescopic heat-insulating tube 9 is fixedly connected to the bottom limit ring 12, and a second elastic component 11 is provided on the outside of the hollow telescopic heat-insulating tube 9, and the end of the second elastic component 11 away from the bottom limit ring 12 is fixed to the top limit ring 10 Fixed connection, the fixed heat-conducting rod 8 is fixedly connected to the heat sink 7 at one end away from the sliding heat-conducting tube 14-2, and the heat sink 7 is located inside the wind collecting shell 5, and the heat is transferred to the sliding heat-conducting tube 14-2 through the heat-conducting sheet 13 that is offset therefrom. Since the sliding heat-conducting tube 14-2 is slidingly connected to the fixed heat-conducting rod 8, the heat can be smoothly transferred from the sliding heat-conducting tube 14-2 to the fixed heat-conducting rod 8, and the fixed heat-conducting rod 8 transfers the heat to the heat sink 7. The heat sink 7 is located inside the wind collecting shell 5, and the cooling fan 6 at the air outlet of the wind collecting shell 5 is started to accelerate the flow of air in the wind collecting shell 5, and quickly dissipate the heat on the heat sink 7, thereby realizing heat dissipation of the hard disk body 24.

[0064] Specifically, when using the hard disk installation device, the following steps are included:

[0065] Install the hard disk body 24 in the housing 1: Place the hard disk body 24 between the symmetrical clamping plate bodies 23. The operator activates and controls the power component 27. The output end of the power component 27 drives the synchronous driving member 26 to rotate. The threaded engagement between the synchronous driving member 26 and the movable plate 15 drives the movable plate 15 to slide toward each other on the support rod 16, thereby driving the first rotating block 20, the linkage plate 21, the second rotating block 22 and the clamping plate body 23 to move, thereby clamping the hard disk body 24.

[0066] Install the hard disk body 24 and the shell 1 in the corresponding electronic device chassis: insert the shell 1 into the corresponding electronic device chassis and clamp it into the corresponding electronic device chassis through the extrusion frame 2. At this time, the extrusion frame 2 will squeeze the rubber block and react on the extrusion frame 2 to fix the shell 1. When removing, press the dial 3 hard to make the extrusion frame 2 leave the server chassis to achieve the removal of the shell 1;

[0067] When the hard disk body 24 is in use, the vibration sensor 28 monitors the vibration of the hard disk body 24 in real time. When the vibration is large, the output end of the power component 27 drives the synchronous driving component 26 to rotate, causing the movable plate 15 to slide, thereby driving the relevant components to increase the clamping force of the clamping plate body 23 on the hard disk body 24, preventing the hard disk body 24 from shaking and reducing the risk of component collision damage; when the vibration is small, the power component 27 controls the reversal of the bidirectional screw to appropriately reduce the clamping force, thereby preventing the hard disk body 24 from being deformed due to long-term excessive extrusion and affecting normal operation, thereby facilitating the adjustment of the clamping degree of the clamping plate body 23, so that the clamping force of the clamping plate body 23 on the hard disk body 24 changes;

[0068] The hard disk body 24 generates heat during operation. This heat is transferred to the sliding heat-conducting tube 14-2 through the heat-conducting sheet 13 that opposes it. Since the sliding heat-conducting tube 14-2 is slidably connected to the fixed heat-conducting rod 8, the heat can be smoothly transferred from the sliding heat-conducting tube 14-2 to the fixed heat-conducting rod 8. The fixed heat-conducting rod 8 transfers the heat to the heat sink 7. The heat sink 7 is located in the air collection housing 5. The cooling fan 6 is started, accelerating the flow of air in the air collection housing 5 and quickly dissipating the heat on the heat sink 7, thereby achieving heat dissipation for the hard disk body 24.

[0069] When the hard disk body 24 is installed or subjected to vibration, the heat conducting plate 13 will drive the sliding heat conducting tube 14-2 to slide on the fixed heat conducting rod 8. The elastic structure composed of the bottom limit ring 12, the hollow telescopic insulation tube 9, the second elastic component 11 and the top limit ring 10 can ensure that the heat conducting plate 13 is always against the outer wall of the hard disk body 24, and can also adapt to the slight movement of the hard disk body 24 to ensure the heat conduction and auxiliary fixing effect.

[0070] The hard disk installation device uses a vibration sensor 28 to monitor the vibration of the hard disk body 24 in real time. It is equipped with a drive component and a unique supporting anti-vibration component linkage structure, which can automatically adjust the clamping force of the splint component according to the vibration frequency. Through an intelligent and precise adjustment mechanism, compared with the traditional fixed anti-vibration method, the anti-vibration, heat dissipation and automatic adjustment functions are integrated into one device. The anti-vibration structure composed of the vibration sensor 28, drive motor, bidirectional screw, movable plate 15, splint body 23, tension spring, etc., and the operating mechanism of their mutual cooperation to automatically adjust the clamping force according to the vibration conditions, each component works together to realize intelligent operation, thereby improving the practicality and convenience of the device.

The hard disk vibration reduction method includes the following steps:

[0073] Step S1: After obtaining that the hard disk body 24 is installed in the cavity, the power component 27 is controlled to move the two adjacent movable plates 15 to the target position;

[0074] Step S2: obtaining the vibration frequency of the splint assembly in real time through the vibration sensor 28;

[0075] Step S3: When the vibration frequency of the clamping plate assembly is greater than or equal to the first preset frequency, the power component 27 is controlled to operate to drive two adjacent movable plates 15 to move closer to each other;

[0076] Step S4: When the vibration frequency of the clamping plate assembly is less than or equal to the second preset frequency, the power component 27 is controlled to operate to drive two adjacent movable plates 15 to move away from each other, and the second preset frequency is less than the first preset frequency.

[0077] The hard disk vibration reduction method obtains the vibration frequency of the clamping plate assembly in real time through the vibration sensor 28, and controls the clamping plate assembly to clamp the hard disk body 24 when the vibration frequency of the clamping plate assembly is greater than or equal to the first preset frequency, thereby reducing the vibration of the hard disk body 24, and controls the clamping plate assembly to reduce the clamping force on the hard disk body 24 when the vibration frequency of the clamping plate assembly is less than or equal to the second preset frequency, thereby preventing excessive squeezing of the hard disk body 24, and avoiding deformation of the hard disk body 24 shell or internal structure due to long-term excessive squeezing, thereby affecting the normal operation of the hard disk body 24, and extending the service life of the hard disk body 24; when the vibration frequency of the clamping plate assembly is between the first preset frequency and the second preset frequency, no adjustment is required to reduce the loss of the power component; when the vibration frequency of the clamping plate assembly is too large, after controlling the power component 27 to clamp the hard disk body 24, the vibration frequency of the clamping plate assembly will decrease, and when the vibration frequency of the clamping plate assembly is reduced to the second preset frequency, the power component 27 can be driven in reverse.

[0078] The hard disk mounting device and hard disk vibration reduction direction have the following beneficial effects:

[0079] 1. The vibration of the hard disk body 24 is monitored in real time through the vibration sensor 28, and the clamping force of the clamping plate body 23 on the hard disk body 24 is automatically adjusted through the driving component. The elastic characteristics of the first elastic component 18 are utilized to effectively absorb and disperse the vibration energy, reduce the damage to the hard disk body 24 caused by vibration, and extend the service life of the hard disk body 24.

[0080] 2. The heat-conducting assembly quickly transfers the heat generated by the hard disk body 24 to the air collecting shell 5 through the heat-conducting sheet 13, the sliding heat-conducting tube 14-2, the fixed heat-conducting rod 8 and the heat dissipation plate 7, and then the heat dissipation is accelerated by the heat dissipation fan 6, which can effectively reduce the operating temperature of the hard disk body 24 and ensure the stable operation of the hard disk body 24. The setting of the elastic structure ensures good contact between the heat-conducting sheet 13 and the hard disk body 24, thereby improving the heat conduction efficiency.

[0081] 3. The driving assembly and the support and anti-vibration assembly cooperate with each other to realize the function of automatically adjusting the clamping force according to the vibration of the hard disk body 24. This intelligent operation mode does not require manual intervention, which improves the convenience of using the device. In the daily operation of the server, the administrator does not need to pay attention to the vibration of the hard disk body 24 at all times. The device will automatically sense and make corresponding adjustments. This not only saves labor costs, but also avoids the risk of damage to the hard disk body 24 due to untimely or inaccurate manual operation, effectively extending the service life of the hard disk body 24 and ensuring data security.

[0082] Of course, on an industrial automation production line, a large number of devices work together through controllers and sensors, and the hard disk body 24 that stores key data and programs in these devices also faces vibration and heat dissipation problems; for example, large CNC machine tools, automated assembly robots, etc., will generate strong vibrations when the equipment is running, and the hard disk body 24 will generate heat after working for a long time; therefore, on an industrial automation production line, the hard disk installation device provided by the present invention can also be used to protect the stable operation of the hard disk body 24, ensure the accurate reading and writing of data during the production process, and avoid production interruptions or product quality problems due to failure of the hard disk body 24.
