Description

Technical Field

[0001] The invention belongs to the field of computer hard disk transportation, and in particular relates to a computer hard disk protection and transportation device. Background Art

[0002] Mechanical hard drives, as essential data storage media, are widely used in data centers, enterprise servers, and scientific research institutions. During transportation, their delicate internal structure, including high-speed spinning platters and sensitive read / write heads, makes them susceptible to vibration, shock, static electricity, and external impact. Failure to implement effective protective measures during transportation can lead to data read / write errors and head damage at best, and even platter scratches and permanent data loss at worst, resulting in significant economic losses and safety risks.

[0003] After searching, a Chinese patent document with publication number CN214356195U was found. The patent discloses a transport rack for computer hard disks, including a fixed base plate, four first shock-absorbing components, a plurality of fixed components and a plurality of second shock-absorbing components. The top of the fixed base plate is vertically installed with a support plate, and the plurality of fixed components are slidably arranged at equal intervals along the height direction of the support plate on one side of the support plate. The four first shock-absorbing components and the plurality of second shock-absorbing components have the same structure, and the four first shock-absorbing components are spaced apart between the fixed base plate and the corresponding fixed components, and the plurality of second shock-absorbing components are spaced apart in groups of four between two adjacent fixed components. It has the advantage of reasonable structural design.

[0004] The computer hard disk transport rack disclosed in the above patent has the advantage of reasonable structural design, but has obvious shortcomings in actual use. First, when in use, the mechanical hard disk of the above patent is inserted into the placement block. When taking and placing the hard disk, it is necessary to unlock the placement block by operating the fixing component and remove the placement block as a whole from the first fixed block before the hard disk on the placement block can be taken and placed. The operation is cumbersome and inefficient, especially in scenarios where frequent access to the hard disk is required. Secondly, the transport rack disclosed in the above patent uses a static slot to insert and fix the mechanical hard disk. The mechanical hard disk is directly inserted into the placement slot. During the transportation process, it is impossible to achieve a stable wrapping of the hard disk body, and there is still a risk of the hard disk being damaged due to shaking.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and examples.

[0031] Example 1: This embodiment provides a computer hard disk protection transport device, such as Figure 1-10 As shown, it includes a cabinet frame 2 fixed on the transfer vehicle 1, and multiple layers of storage cavities are evenly arranged in the cabinet frame 2 from top to bottom. A storage unit 3 is provided on the left and right sides of each layer of storage cavity. The cabinet frame 2 is composed of a top plate, a bottom plate and front and rear side plates. The left and right ends of the cabinet frame are open to facilitate the extension and retraction of the storage unit; there are many ways to set up the storage cavity. In this embodiment, n platform plates 21 are fixed at intervals from top to bottom inside the cabinet frame, and the platform plates divide the internal space of the cabinet frame into n+1 layers of storage cavities evenly from top to bottom.

[0032] like Figure 3-9 As shown, the storage unit 3 includes a folding box 4, a hard disk baffle 5, a slide 6, a torsion spring 31, an folding drive mechanism 7 and a retraction drive mechanism 8. The slide 6 is installed on the bottom of the storage cavity along the horizontal sliding direction and is connected to the retraction drive mechanism. The retraction drive mechanism is connected to a control unit. The bottom of the folding box is hingedly installed on the slide. The control unit can drive the slide 6 to drive the folding box to slide outward along the horizontal direction through the retraction drive mechanism, and extend the cabinet frame 2 through the opening on the same side.

[0033] There are many ways to install the slide 6. For example, the bottom of the storage cavity on the inner side of the opening is provided with multiple slide rails at parallel intervals along the longitudinal direction, and an anti-slip slider is installed in the slide rail. The anti-slip slider is fixedly connected to the bottom of the slide. When the slide drives the anti-slip slider to slide outward to the end of the slide rail, the unfolding box passes through the opening and is completely extended from the cabinet frame 2.

[0034] like Figure 7As shown, the retraction and extension drive mechanism 8 includes a drive component and an active oil cylinder 83, a drive component and a control unit, and the drive component can push the slide plate 6 outward through the active oil cylinder 83; the drive component includes a screw 81, the screw 81 is arranged longitudinally, and both ends of the screw are rotatably installed in the storage cavity through bearings and bearing seats, and the front end of the screw extends forward from the storage cavity and is transmission-connected to a drive motor, which is connected to the control unit, and the control unit controls the drive motor of the corresponding storage unit to work according to demand; the front and rear sections of the screw 81 are symmetrically covered with screw sleeves 82, and the thread directions of the two screw sleeves 82 are set in opposite directions, and the inner end of the slide plate between the two screw sleeves 82 is longitudinally There are two active cylinders 83 symmetrically hinged, and the tail ends of the two active cylinders 83 are hinged to the screw sleeves on the same side respectively. A supporting top spring is matched in the active cylinder. The supporting top spring is used to support the piston in the active cylinder so that the telescopic end of the active cylinder remains in a normally extended state. When the screw is driven to rotate, the two screw sleeves will move toward each other or move away from each other in opposite directions following the rotation of the screw under the constraint of the active cylinder. In this process, when the two screw sleeves move closer, the two screw sleeves will slide outward and extend out of the cabinet frame through the active cylinder pushing the sliding plate. Conversely, when the two screw sleeves move away from each other in opposite directions, the two screw sleeves will slide inward and retract into the cabinet frame through the active cylinder pulling the sliding plate.

[0035] In the computer hard disk protection and transfer device provided in this embodiment, the screws of the two storage units in the same storage cavity are rotatably installed on the upper and lower cavity walls of the storage cavity respectively. A device box 22 is fixedly installed on the front side of the cabinet frame, and the drive motor is fixedly installed in the device box. The screw extends into the device box and is transmission-connected to the corresponding drive motor. By alternating the screws up and down, the installation space required for the two storage units can be effectively reduced.

[0036] A plurality of hard disk slots 41 are evenly spaced longitudinally inside the flip box 4 for inserting the hard disk 9. An internal protective component is provided in the hard disk slot, and the internal protective component includes a bottom air bag 42 installed at the bottom of the hard disk slot. An air bag ring group connected to the bottom air bag 42 is provided in the hard disk slot 41 above the bottom air bag 42. The air bag ring group includes a plurality of annular air bags 43 arranged at vertical intervals. The annular air bags 43 are connected to the bottom air bag 42, and the bottom air bag is in a normally expanded state. In this embodiment, the bottom air bag 42 is a bellows-shaped air bag. When the hard disk is inserted into the hard disk slot, the hard disk will pass through the annular air bags in the air bag ring group in turn and collide with the bottom air bag 42. When the hard disk is pushed, the hard disk will squeeze the bottom air bag 42, so that the bottom air bag 42 discharges part of the gas into each annular air bag 43 in the air bag ring group, so that the annular air bag 43 expands and wraps the hard disk.

[0037] A flip slot 61 is parallel to the slide plate 6 on the outside of the flip box 4. A rotating shaft 62 is rotatably mounted within the flip slot 61. The hard drive baffle 5 is fixedly mounted on the rotating shaft. The top of the hard drive baffle extends upward and is fixed with a buffer member located on the end of the hard drive baffle facing the flip box 4. In this embodiment, the buffer member includes multiple top airbags 51 spaced longitudinally. The top airbags are fixed to the end of the hard drive baffle facing the flip box above the rotating shaft, and the top airbags correspond one-to-one with the hard drive slots.

[0038] The slides 6 on the left and right sides of the flip box 4 are symmetrically provided with drive slots 63 that communicate with the flip slots. The flip drive mechanism 7 includes a slave cylinder 71 fixed transversely within the drive slots. Each drive slot 63 is fitted with a slave cylinder 71, which is connected to the master cylinder 83 via a hydraulic pipe. The telescopic ends of the slave cylinders 71 face the flip slots and are hingedly connected to support rods 72. The support rods 72 can be hinged in various ways, for example: a connecting block 73 is fixedly mounted at the telescopic end of the slave cylinder, with a fixed shaft provided on the connecting block 73, and the bottom end of the support rod 72 is rotatably mounted on the fixed shaft. The left and right end surfaces of the flip box are symmetrically and slidably mounted with slides 74. There are various ways to install the slides 74, for example: the slides 74 are matched and fitted on the guide rails 75, and the guide rails 75 are fixedly mounted on the flip box; the top of the support rod is hinged to the slide on the same side, and when the flip box is flipped around the bottom end and placed flat on the slide, the sliding trajectory of the slide is parallel to the moving trajectory of the telescopic end of the driven cylinder 71. When the control unit pushes the active cylinder 83 to push the slide 6 outward to the limit length through the drive assembly, the drive assembly continues to push the active cylinder 83, driving the active cylinder 83 to compress, and the active cylinder 83 controls the telescopic end of the driven cylinder 71 to retract through the oil pipe, thereby driving the flip box to flip and lift around the bottom end.

[0039] Specifically: the oil holes at the head end of the two active oil cylinders are connected to the oil holes at the tail end of the slave oil cylinder on the same side through oil pipes, and the oil holes at the tail end of the two active oil cylinders are connected to the oil holes at the head end of the slave oil cylinder on the same side through oil pipes. Figure 7 and Figure 10 As shown, when the two screw sleeves move toward each other and approach each other, and the push-up slide plate of the active oil cylinder slides outward to the maximum length, the screw continues to rotate to drive the two screw sleeves to move toward each other. At this time, the support top spring in the active oil cylinder will be squeezed and compressed, causing the telescopic end of the active oil cylinder to retract into the cylinder barrel for compensation. In this process, as the piston inside the active oil cylinder moves, the hydraulic oil is discharged from the piston chamber at the bottom of the active oil cylinder and flows into the piston chamber at the top of the driven oil cylinder, driving the telescopic end in the driven oil cylinder to retract, thereby driving the slide to slide toward the bottom of the flip box, and after the slide slides to the limit position, driving the flip box to flip and lift around the bottom end.

[0040] Furthermore, the oil pipe 85 between the oil hole at the head end of the active oil cylinder 83 and the oil hole at the tail end of the slave oil cylinder is connected to a negative pressure compensator 86, and the oil pipe 85 between the oil hole at the tail end of the active oil cylinder and the oil hole at the head end of the slave oil cylinder is connected to a positive pressure compensator 87. The negative pressure compensator 86 includes a negative pressure compensation cylinder body 861 connected to the oil pipe. A negative pressure piston 862 is installed in the negative pressure compensation cylinder body 861, and a top spring a863 is installed in the cylinder body above the negative pressure piston 862. In the natural state, the top spring a pushes the negative pressure piston toward the bottom of the cylinder, and hydraulic oil is stored in the cylinder body above the negative pressure piston. When the telescopic end of the active oil cylinder 83 retracts into the cylinder barrel, it draws hydraulic oil from the piston chamber at the tail end of the slave oil cylinder. The active oil cylinder 83 will simultaneously draw hydraulic oil from the negative pressure compensator to perform volume compensation. The positive pressure compensator 87 comprises a positive pressure compensator cylinder 871 connected to a hydraulic line. A positive pressure piston 872 is mounted within the positive pressure compensator cylinder, and a top spring b873 is mounted within the cylinder below the positive pressure piston. In its natural state, the top spring b pushes the negative pressure piston toward the top of the cylinder. When the telescopic end of the master cylinder 83 retracts into the barrel, the hydraulic oil in the rear piston chamber of the master cylinder 83 is pressurized into the piston chamber at the top of the slave piston. Excess hydraulic oil, due to the volume difference, is forced into the positive pressure compensator, providing volume compensation.

[0041] The torsion spring is installed between the rotating shaft and the flip groove. When the flip box rotates around the bottom end and is placed flat on the slide, the telescopic end of the driven cylinder continues to extend, which will push the hard disk baffle below the rotating shaft to flip around the rotating shaft, thereby twisting the torsion spring and driving the buffer to push the hard disk into the hard disk slot. During this process, the telescopic end of the driven cylinder will drive the slide to slide toward the top of the flip box through the support rod 72, so that after the flip box rotates around the bottom end and is placed flat on the slide, the driven cylinder still has room to extend.

[0042] Specifically: Figure 8 and Figure 9As shown, torsion springs 31 are installed in the flip grooves 61 on the left and right sides of the hard disk baffle 5. The torsion springs 31 are matched and fitted on the corresponding rotating shafts. The two ends of the torsion springs 31 respectively abut against the inner walls of the hard disk baffle 5 and the flip groove 61. In the natural state, the torsion springs 31 drive the hard disk baffle 5 to rotate toward the side away from the flip box. A support airbag 52 is provided between the hard disk baffle 5 and the driven cylinder below the rotating shaft. A cavity is provided in the slide plate 6 between the two driving grooves 63. The cavity is connected to the driving grooves 63 and the flip groove 61 on both sides. A connecting plate 84 is provided in the cavity. The two ends of the connecting plate are fixedly connected to the telescopic ends of the driven cylinders in the driving grooves on both sides. When the telescopic ends of the driven cylinders are extended or retracted, the connecting plate is driven to move synchronously along the cavity, approaching or away from the flip groove. The support airbag 52 is fixedly installed on the end surface of the connecting plate facing the flip groove and is in a normally inflated state. In this embodiment, the support airbag 52 is a bellows-shaped airbag, which is connected to each top airbag. When the flip box rotates around the bottom end and is placed flat on the slide, the telescopic end of the driven oil cylinder continues to extend and pushes the baffle to stand upright around the rotating axis through the support airbag, and squeezes the support airbag to drive each top airbag 51 to expand and push the hard disk into the hard disk slot.

[0043] The control unit includes a controller and a control panel. The controller is connected to the control motors of each retractable and extendable drive mechanism and identifies the control motors of each retractable and extendable drive mechanism. The control panel is connected to the controller and is installed on the device box 22. The control panel can be used to select and control the extension, extension, folding and retraction of the corresponding storage unit.

[0044] The computer hard drive protection and transfer device provided by this embodiment automatically extends and deploys the desired storage unit as needed via the control panel. After the storage unit's slide, carrying the flip box, is fully extended from the cabinet frame, the retraction and deployment drive mechanism engages the two slave cylinders of the flip drive mechanism. The telescopic ends of the slave cylinders retract, driving the slide toward the bottom of the flip box. After the slide reaches its limit position, the flip box is tilted and lifted around its bottom, making it easier for the operator to access the hard drive. During the movement of the slide, the hard drive baffle is unobstructed and, driven by a torsion spring, rotates around its axis, forcing the buffer member to clear the flip box. After the hard drive is inserted, the control panel automatically retracts the storage unit. At this point, the controller controls the screw of the storage unit's retraction and deployment drive mechanism to rotate in the opposite direction. The counter-rotating screw drives the two screw sleeves away from each other in opposite directions. The telescopic ends of the two active cylinders, acting on the compression spring, extend and reset first, thereby driving the telescopic ends of the two slave cylinders to extend and reset synchronously. After the slide moves to the top side of the flip box and is reset, as the screw continues to rotate, the two screw sleeves pull the slide inward through the two active oil cylinders to drive the flat flip box to retract into the cabinet frame.

[0045] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
