Description

Technical Field

[0001] This invention relates to the field of hard drive tray technology, specifically a server hard drive insertion and removal protection mechanism. Background Technology

[0002] Server hard drives are storage hard drives specifically designed for use in servers. Unlike ordinary computer hard drives, they are designed for stability and durability, and can work continuously for long periods of time. They are mainly used to store system files, data, and business files. They offer more stable read and write operations, stronger fault tolerance, and are less prone to damage. Server hard drives are typically installed in hard drive caddies during use.

[0003] Currently, traditional hard drives are mostly fixed to the hard drive rack with screws, making hard drive replacement cumbersome and unable to meet the needs of rapid server maintenance. At the same time, when manually plugging and unplugging hard drives, problems such as uneven force, oblique insertion, and forceful pulling are likely to occur, which can easily wear down the hard drive interface and server slot, reducing the lifespan of the hard drive and the entire machine. To address this, we propose a server hard drive plugging and unplugging protection mechanism. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a server hard drive insertion and removal protection mechanism. This mechanism solves the problems of traditional hard drives being fixed to the hard drive rack with screws, making hard drive replacement cumbersome and unable to meet the needs of rapid server maintenance. Furthermore, manual insertion and removal of hard drives can easily lead to uneven force, oblique insertion, or forceful pulling, which can easily wear down the hard drive interface and server slot, reducing the lifespan of the hard drive and the entire machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a server hard drive insertion / removal protection mechanism, comprising a bracket for placing a hard drive, a tray plate installed inside the bracket, a placement slot adapted to a hard drive interface opened on one side of the bracket, a protective component provided on the surface of the bracket, the protective component including a cavity, the cavity being opened inside the tray plate, two symmetrically arranged sliding rods slidably connected to the inner wall of the bracket, one end of each sliding rod extending into the cavity, a stop plate installed at the end of each sliding rod away from the cavity, the stop plate sliding inside the bracket, a piston block fixedly connected to the end of each sliding rod in the cavity, the piston block communicating with the inner wall of the cavity, and openings on both sides of the bracket. The device includes a storage slot, and a conduit is installed inside the bracket, connecting the cavity to the storage slot. A locking block is slidably connected in the storage slot to engage with a slot inside the server hard drive rack. When the hard drive is inserted into the bracket and presses against the backing plate, the sliding rod drives the piston block to compress the gas in the cavity. The gas enters the storage slot through the conduit, thereby pushing the locking block out to achieve locking with the server hard drive rack. This solution achieves automatic locking upon hard drive insertion by pressing against the backing plate during hard drive insertion and using gas transmission to drive the locking block to automatically extend and engage with the server hard drive rack, eliminating the need for additional operation. This effectively prevents the hard drive from loosening, shifting, or falling out during operation due to vibration or accidental contact, significantly improving the stability and security of server hard drive use.

[0006] Preferably, a rotating rod is rotatably connected to the inner wall of the bracket, and a rotating block is fixedly connected to one end of the rotating rod. The rotating block rotates on the inner wall of the bracket. A limiting hole is opened on the side of the cavity near the rotating rod. The limiting hole is arc-shaped. A limiting block is fixedly connected to the side of the rotating block near the cavity. One end of the limiting block is inserted into the limiting hole. The limiting block slides against the inner wall of the limiting hole. An exhaust hole is opened on the surface of the rotating block. The limiting hole is located on the movement trajectory of the exhaust hole and is used to discharge compressed air in the cavity. The locking action is achieved by a pneumatic linkage structure, which has fast transmission response, simple and reliable structure, and eliminates the need for complex components such as motors and electronic controls, reducing the risk of failure. At the same time, it reduces installation and operation steps and improves hard drive insertion and removal efficiency.

[0007] Preferably, one end of the rotating rod extends into the cavity, and a protrusion is fixedly connected to the end of the rotating rod located in the cavity. A torsion spring is fixedly connected to the side of the protrusion near the rotating rod. The torsion spring is sleeved on the rotating rod, and the end of the torsion spring away from the protrusion is fixedly connected to the inner wall of the cavity. The torsion spring, in conjunction with the limiting block, is used to restrict the rotation of the rotating block. After the venting operation is completed, the rotating block resets. The cavity can be vented and unlocked by rotating the rotating block. The automatic reset is achieved with the help of the torsion spring. The unlocking operation is simple and quick, and the cavity sealing is guaranteed, allowing the device to be used repeatedly and with a longer service life.

[0008] Preferably, the piston block is fixedly connected to two symmetrically arranged compression springs at the end away from the slide rod, and the end of the compression spring away from the piston block is fixedly connected to the inner wall of the cavity.

[0009] Preferably, a handle is installed on the side of the rotating block away from the bracket, and the handle is used to drive the rotating block to rotate.

[0010] Preferably, a tension spring is fixedly connected to one side of the card block, and the end of the tension spring away from the card block is fixedly connected to the inner wall of the storage slot. One side edge of the card block is chamfered to retract after contacting the server hard drive rack. The card block adopts a chamfered structure and works with a tension spring to automatically retract when inserted and automatically reset after being pulled out. This does not affect the normal insertion and removal of the hard drive and ensures reliable locking. The overall structure has strong compatibility.

[0011] Preferably, the corner of the abutment away from the slide bar is chamfered, and multiple equally spaced rubber blocks are installed on the side of the abutment away from the slide bar. The overall structure is reasonably laid out, highly integrated, and has complete protection functions. It is suitable for various rack-mounted server hard drive installation scenarios and has strong practicality and versatility.

[0012] Preferably, both sides of the bracket are provided with pull-out components for protecting the hard drive interface. The pull-out components, consisting of a servo motor, a screw, and a push rod, are provided on both sides of the bracket. They can push the hard drive outward smoothly and at a constant speed, avoiding manual pulling that could cause interface wear, deformation, or poor contact, thus providing effective protection for the hard drive and server interface.

[0013] Preferably, the pull-out assembly includes two guide bars, symmetrically mounted on both sides of the bracket. The lower corners of the guide bars are chamfered. A servo motor is installed inside each guide bar. A guide groove is formed on one side of each guide bar, and a push rod is slidably connected to the guide groove. A screw is fixedly connected to the drive end of the servo motor, with one end extending into the guide groove. The screw is threadedly connected to the inner wall of the push rod. A stop block is fixedly connected to the end of the push rod away from the servo motor. When the hard drive is pulled out, the servo motor drives the screw to rotate, causing the push rod and the stop block to move away from the servo motor. The stop block then abuts against the inside of the server hard drive rack, causing the bracket and hard drive to be pulled out stably. The guide bars guide the bracket insertion and removal, ensuring accurate hard drive interface connection. Combined with the sealing block, dust protection is achieved, further improving the overall durability and environmental adaptability of the device.

[0014] Preferably, both sides of the bracket are fixedly connected to sealing blocks for sealing the grooves on the server hard drive rack that accommodate the guide strip.

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] 1. In this invention, the solution uses a pressure plate when the hard drive is inserted, and a gas-driven block automatically extends and engages with the server hard drive rack, so that the hard drive is automatically locked upon insertion without additional operation. This effectively prevents the hard drive from becoming loose, shifting or falling out due to vibration or accidental contact during operation, and significantly improves the stability and security of the server hard drive.

[0017] 2. In this invention, a pneumatic linkage structure is used to achieve the locking action, which has fast transmission response, simple and reliable structure, no need for complex components such as motors and electronic controls, reduces the risk of failure, and at the same time reduces installation and operation steps, improving hard drive insertion and removal efficiency.

[0018] 3. In this invention, the cavity can be vented and unlocked by rotating the rotating block, and automatic reset can be achieved with the help of the torsion spring. The unlocking operation is simple and quick, and the cavity sealing can be guaranteed, so that the device can be used repeatedly and has a longer service life.

[0019] 4. In this invention, the card block adopts a chamfered structure and is equipped with a tension spring, which can automatically retract when inserted and automatically reset after being pulled out. This does not affect the normal insertion and removal of the hard drive, and can ensure reliable locking. The overall structure has strong compatibility.

[0020] 5. In this invention, the bracket is equipped with a pull-out assembly consisting of a servo motor, a screw, and a push rod on both sides, which can smoothly and evenly push the hard drive outward, avoiding interface wear, deformation, or poor contact caused by manual pulling, and effectively protecting the hard drive and server interface.

[0021] 6. In this invention, the guide bar can guide the insertion and removal of the bracket, ensuring accurate docking of the hard drive interface, and together with the sealing block, it can achieve dust protection, further improving the overall durability and environmental adaptability of the device.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] refer to Figures 1-7The server hard drive insertion and removal protection mechanism shown includes a bracket 1 for placing hard drives, a tray 2 installed inside the bracket 1, a placement slot 3 adapted to the hard drive interface on one side of the bracket 1, a protective component 4 on the surface of the bracket 1, the protective component 4 including a cavity 411 located inside the tray 2, two symmetrically arranged sliding rods 415 slidably connected to the inner wall of the bracket 1, one end of the sliding rod 415 extending into the cavity 411, a stop plate 416 installed at the end of the sliding rod 415 away from the cavity 411, the stop plate 416 sliding inside the bracket 1, a piston block 48 fixedly connected to the end of the sliding rod 415 in the cavity 411, the piston block 48 communicating with the inner wall of the cavity 411, and storage slots 412 on both sides of the bracket 1. A conduit 410 connects the cavity 411 and the storage slot 412. A locking block 414 is slidably connected in the storage slot 412 to engage with the slot inside the server hard drive rack. When the hard drive is inserted into the bracket 1 and the pressure plate 416 is pressed, the slide rod 415 drives the piston block 48 to compress the gas in the cavity 411. The gas enters the storage slot 412 through the conduit 410, thereby pushing the locking block 414 out to achieve locking with the server hard drive rack. This solution uses gas transmission to drive the locking block 414 to automatically extend and engage with the server hard drive rack when the hard drive is inserted and the pressure plate 416 is pressed. This achieves automatic locking upon insertion of the hard drive without additional operation, effectively preventing the hard drive from loosening, shifting, or falling out due to vibration or accidental contact during operation, and significantly improving the stability and safety of server hard drive use.

[0032] The bracket 1 has a rotating rod 47 rotatably connected to its inner wall. One end of the rotating rod 47 is fixedly connected to a rotating block 41, which rotates on the inner wall of the bracket 1. A limit hole 44 is opened on the side of the cavity 411 near the rotating rod 47. The limit hole 44 is arc-shaped. A limit block 43 is fixedly connected on the side of the rotating block 41 near the cavity 411. One end of the limit block 43 is inserted into the limit hole 44, and the limit block 43 slides against the inner wall of the limit hole 44. An exhaust hole 42 is opened on the surface of the rotating block 41. The limit hole 44 is located on the movement trajectory of the exhaust hole 42 and is used to discharge the compressed air in the cavity 411. The locking action is achieved by using a pneumatic linkage structure. The transmission response is fast, the structure is simple and reliable, and there is no need for complex components such as motors and electrical controls, which reduces the risk of failure. At the same time, it reduces the installation and operation steps and improves the efficiency of hard drive insertion and removal.

[0033] One end of the rotating rod 47 extends into the cavity 411. A protrusion 45 is fixedly connected to the end of the rotating rod 47 located in the cavity 411. A torsion spring 46 is fixedly connected to the side of the protrusion 45 near the rotating rod 47. The torsion spring 46 is sleeved on the rotating rod 47. The end of the torsion spring 46 away from the protrusion 45 is fixedly connected to the inner wall of the cavity 411. The torsion spring 46, together with the limiting block 43, is used to limit the rotation of the rotating block 41. After the venting operation is completed, the rotating block 41 resets. The cavity 411 can be vented and unlocked by rotating the rotating block 41. Automatic reset is achieved with the help of the torsion spring 46. The unlocking operation is simple and quick, and the sealing of the cavity 411 is guaranteed, so the device can be used repeatedly and has a longer service life.

[0034] Two symmetrically arranged compression springs 49 are fixedly connected to the end of the piston block 48 away from the slide rod 415. The end of the compression spring 49 away from the piston block 48 is fixedly connected to the inner wall of the cavity 411. When it is necessary to unlock and remove the hard drive, the handle 418 rotates the rotating block 41, so that the exhaust hole 42 on the rotating block 41 communicates with the limiting hole 44 on the cavity 411. The compressed air in the cavity 411 is discharged through the limiting hole 44 and the exhaust hole 42, and the internal pressure of the cavity 411 is reduced. The limiting block 43 on the rotating block 41 cooperates with the arc-shaped limiting hole 44 to limit the rotation angle of the rotating block 41. The torsion spring 46 can drive the rotating block 41 to automatically reset after the exhaust is completed, and re-close the cavity 411 to ensure that the air pressure can be normally established to drive the card block 414 when the hard drive is installed next time.

[0035] A handle 418 is installed on the side of the rotating block 41 away from the bracket 1. The handle 418 is used to drive the rotating block 41 to rotate.

[0036] The locking block 414 has a tension spring 413 fixedly connected to one side. The end of the tension spring 413 away from the locking block 414 is fixedly connected to the inner wall of the storage slot 412. One edge of the locking block 414 is chamfered to retract after contacting the server hard drive rack. The chamfered structure of the locking block 414, together with the tension spring 413, allows it to automatically retract when inserted and automatically reset after being pulled out. This does not affect the normal insertion and removal of the hard drive and ensures reliable locking. The overall structure has strong compatibility. The tension spring 413 on one side of the locking block 414 can pull the locking block 414 back into the storage slot 412 when unlocking. The chamfered structure of the edge of the locking block 414 allows it to contact the server hard drive rack and automatically retract during hard drive insertion without affecting the normal insertion of the hard drive. The compression spring 49 on one side of the piston block 48 can rotate the rotating block 41 and drive the piston block 48 to reset after the hard drive is removed, preparing for the next locking action.

[0037] Among them, the corner of the back plate 416 away from the slide bar 415 is chamfered, and multiple equally spaced rubber blocks 417 are installed on the side of the back plate 416 away from the slide bar 415. The overall structure is reasonably laid out, highly integrated, and has a complete protection function. It is suitable for various rack-mounted server hard drive installation scenarios and has strong practicality and versatility.

[0038] The bracket 1 has pull-out components 5 on both sides to protect the hard drive interface. The pull-out components 5 on both sides of the bracket 1 consist of a servo motor 52, a screw 53, and a push rod 54. They can push the hard drive out smoothly and at a constant speed, avoiding manual pulling that could cause interface wear, deformation, or poor contact, thus providing effective protection for the hard drive and server interface.

[0039] The pull-out assembly 5 includes two guide bars 51, which are symmetrically installed on both sides of the bracket 1. The lower corners of the guide bars 51 are chamfered. A servo motor 52 is installed inside the guide bar 51. A guide groove 57 is provided on one side of the guide bar 51, and a push rod 54 is slidably connected in the guide groove 57. A screw 53 is fixedly connected to the drive end of the servo motor 52. One end of the screw 53 extends into the guide groove 57, and the screw 53 is threadedly connected to the inner wall of the push rod 54. A stop block 55 is fixedly connected to the end of the push rod 54 away from the servo motor 52. When the hard drive is pulled out, the servo motor 52 drives the screw 53 to rotate, which causes the push rod 54 and the stop block 55 to move away from the servo motor 52. Then the stop block 55 abuts against the inside of the server hard drive rack, which drives the bracket 1 and the hard drive to be pulled out stably. The guide bar 51 can guide the insertion and removal of the bracket 1 to ensure accurate connection of the hard drive interface. Together with the sealing block 56, it can achieve dust protection and further improve the overall durability and environmental adaptability of the device.

[0040] Both sides of the bracket 1 are fixedly connected with sealing blocks 56, which are used to block the grooves of the server hard disk rack that are adapted to the guide strip 51.

[0041] Working principle of the invention: When the server hard drive insertion and removal protection mechanism is in use, the hard drive is inserted into the bracket 1 along the placement slot 3 of the bracket 1. During the insertion process, the hard drive will squeeze the abutment plate 416 on the inner side of the bracket 1. The abutment plate 416 is pushed by the force to move the slide rod 415 and the piston block 48 in the cavity 411, compressing the gas inside the cavity 411. The compressed gas enters the storage slots 412 on both sides of the bracket 1 through the conduit 410, pushing the locking block 414 in the storage slot 412 to extend outward, so that the locking block 414 engages with the locking slot inside the server hard drive rack, realizing automatic locking after the hard drive is inserted, preventing the hard drive from loosening or falling out due to vibration or accidental contact during use, thus achieving the effect of insertion and removal protection.

[0042] The tension spring 413 on one side of the locking block 414 can pull the locking block 414 back into the storage slot 412 when unlocking; the chamfered structure on the edge of the locking block 414 can contact the server hard drive rack and automatically retract during hard drive insertion without affecting the normal insertion of the hard drive; the compression spring 49 on one side of the piston block 48 can rotate the rotating block 41 and drive the piston block 48 to reset after the hard drive is removed, in preparation for the next locking action;

[0043] When it is necessary to unlock and remove the hard drive, the handle 418 is used to rotate the rotating block 41, so that the exhaust hole 42 on the rotating block 41 is connected to the limiting hole 44 on the cavity 411. The compressed air in the cavity 411 is discharged through the limiting hole 44 and the exhaust hole 42, and the internal pressure of the cavity 411 is reduced. The limiting block 43 on the rotating block 41 cooperates with the arc-shaped limiting hole 44 to limit the rotation angle of the rotating block 41. The torsion spring 46 can drive the rotating block 41 to automatically reset after the exhaust is completed, and re-close the cavity 411 to ensure that the air pressure can be properly established to drive the card block 414 when the hard drive is installed next time.

[0044] When the hard drive is removed, the servo motor 52 drives the screw 53 to rotate, causing the push rod 54 and the stop block 55 to move outward along the guide groove 57. The stop block 55 abuts against the inside of the server hard drive rack, and the reaction force pushes the bracket 1 and the hard drive outward smoothly, avoiding direct pulling of the hard drive and damage to the interface. The guide bar 51 guides the insertion and removal movement of the bracket 1 to ensure accurate docking between the hard drive interface and the server interface. The sealing block 56 on the bracket 1 can seal the corresponding groove on the server hard drive rack, which plays a role in dust prevention and structural protection.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
