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 transportation device. Background Art

[0002] As an important data storage medium, mechanical hard disks are widely used in data centers, enterprise servers and scientific research institutions. During the transportation process, due to their precise internal structure, including high-speed rotating disks and sensitive read-write heads, they are easily affected by factors such as vibration, impact, static electricity and external collisions. If effective protective measures are not taken during the transportation process, data read and write errors and head damage may occur at the least, and disk scratches or even permanent data loss may occur at the worst, causing serious economic losses and safety hazards.

[0003] After searching, a Chinese patent document with publication number CN214356195U was found. The patent discloses a transport rack for a computer hard disk, including a fixed base plate, four first shock-absorbing components, a plurality of fixed components and a plurality of second shock-absorbing components. A support plate is vertically installed on the top of the fixed base plate, and a plurality of fixed components are slidably arranged at equal intervals on one side of the support plate along the height direction 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 between two adjacent fixed components in groups of four, which 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 it has obvious shortcomings in actual use. First, when the above patent is in use, the mechanical hard disk 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. Summary of the invention

[0005] In view of the defects and problems of existing computer hard disk transport devices, the present invention provides a computer hard disk protection transport device to solve the problems of inconvenient placement and poor protection effect of existing equipment, and ensure the safety and operating efficiency of mechanical hard disks during transportation.

[0006] The solution adopted by the present invention to solve its technical problems is as follows: A computer hard disk protection and transfer device includes a cabinet frame fixed on a transfer cart. The cabinet frame is provided with multiple layers of storage cavities. On both sides of each layer of storage cavity, there is a storage unit. The storage unit includes a flip box, a hard disk baffle, a slide plate, a torsion spring, a flip drive mechanism, and a retraction and extension drive mechanism. The slide plate is slidably installed at the bottom of the storage cavity. The retraction and extension drive mechanism includes a drive assembly and a main cylinder. The drive assembly is connected to a control unit, and the drive assembly can push the slide plate outwards through the main cylinder. The bottom of the flip box is hingedly installed on the slide plate. A plurality of hard disk slots are longitudinally spaced in the flip box, and an inner protection assembly is provided in the hard disk slots. A flip groove is parallelly arranged on the slide plate outside the flip box, and a rotating shaft is installed in the flip groove. The hard disk baffle is fixedly sleeved on the rotating shaft, and a buffer member is fixed at one end of the hard disk baffle facing the flip box. Drive grooves communicating with the flip groove are symmetrically arranged on the slide plates on both sides of the flip box. The flip drive mechanism includes a slave cylinder fixedly arranged in the drive groove along the transverse direction. The slave cylinder is connected to the main cylinder through an oil pipe. The telescopic end of the slave cylinder faces the flip groove and is hinged with a support rod. Slide seats are symmetrically installed on the two end faces of the flip box. The top end of the support rod is hinged with the slide seat on the same side. When the control unit pushes the main cylinder through the drive assembly to push the slide plate outwards to the limit length, the drive assembly continues to push the main cylinder, causing the main cylinder to compress. The main cylinder drives the telescopic end of the slave cylinder to retract through the oil pipe. The retracted slave cylinder drives the flip box to turn up around the bottom end. The torsion spring is installed between the rotating shaft and the flip groove. When the flip box lies flat on the slide plate around the bottom end, the telescopic end of the slave cylinder extends, pushing the hard disk baffle below the rotating shaft to turn around the rotating shaft, thereby twisting the torsion spring to drive the buffer member to push the hard disk into the hard disk slot.

[0007] Preferably, the drive assembly includes a screw rod. The screw rod is rotatably installed longitudinally in the storage cavity between the two slide plates. The screw rod is drivingly connected to a drive motor, and the drive motor is connected to the control unit. Symmetrically sleeved on the front and rear sections of the screw rod are two screw sleeves with opposite thread directions. Along the longitudinal direction, symmetrically hinged to the inner ends of the slide plates between the two screw sleeves are two main cylinders. A support spring is arranged in the main cylinder in a matching manner. The tail ends of the two main cylinders are respectively hinged to the screw sleeves on the same side. The oil holes at the heads of the two main cylinders are respectively communicated with the oil holes at the tails of the slave cylinders on the same side through oil pipes, and the oil holes at the tails of the two main cylinders are respectively communicated with the oil holes at the heads of the slave cylinders on the same side through oil pipes.

[0008] Preferably, the screw rods of the storage units on the same layer are respectively rotatably installed on the upper and lower cavity walls of the storage cavity. A device box is fixedly installed on the front side of the cabinet frame. The drive motor is fixedly installed in the device box, and the screw rod extends into the device box and is drivingly connected to the corresponding drive motor.

[0009] Preferably, a negative pressure compensator is also connected to the oil pipe connecting the oil hole at the head end of the active oil cylinder and the oil hole at the tail end of the driven oil cylinder; a positive pressure compensator is also connected to the oil pipe connecting the oil hole at the tail end of the active oil cylinder and the oil hole at the head end of the driven oil cylinder.

[0010] Preferably, the inner protection component includes a bottom airbag installed at the bottom of the hard disk slot. An airbag ring group communicated with the bottom airbag is arranged in the hard disk slot above the bottom airbag. In the non-force state, the bottom airbag is in an inflated state.

[0011] Preferably, the buffer member includes a plurality of top airbags arranged at intervals longitudinally. The top airbags are fixed on the side of the hard disk baffle facing the unfolding box, and the top airbags correspond to the hard disk slots one by one.

[0012] Preferably, a support airbag is arranged between the lower end of the hard disk baffle and the driven oil cylinder. The support airbag is communicated with each top airbag. When the unfolding box is placed flat on the sliding plate around the bottom end, the retracting and extending drive mechanism continues to drive the telescopic end of the driven oil cylinder to extend and push the support airbag. The support airbag pushes the hard disk baffle to flip around the rotating shaft. The telescopic end of the driven oil cylinder squeezes the support airbag to drive each top airbag to expand. The expanded top airbags push the hard disk.

[0013] Preferably, both left and right ends of the cabinet frame are open. n platform plates are fixedly arranged in the cabinet frame at intervals from top to bottom. The platform plates evenly divide the internal space of the cabinet frame into n + 1 storage cavities from top to bottom.

[0014] Preferably, the control unit includes a controller and a control panel. The controller is connected to each retracting and extending drive mechanism and identifies each retracting and extending drive mechanism. The control panel is connected to the controller.

[0015] Advantages of the present invention: 1. For the computer hard disk protection and transfer device provided by the present invention, through the three-stage linkage design of the bottom airbag, the annular airbag and the top airbag, the all-round circumferential self-adaptive protection of the hard disk is realized. When the top airbag pushes the hard disk, the bottom airbag supplies air to the annular airbag. The annular airbag expands to wrap the side of the hard disk to form a radial buffer. The top airbag and the bottom airbag cooperate with the top and bottom ends of the hard disk to form a multi-dimensional shock absorption system, significantly reducing the damage risk of vibration to the hard disk during transportation.

[0016] 2. For the computer hard disk protection and transfer device provided by the present invention, the active oil cylinder and the driven oil cylinder driven by hydraulic pressure are linked, combined with the bidirectional screw drive, to realize the seamless connection between the telescopic of the sliding plate and the flipping of the unfolding box, which is convenient for taking and placing the hard disk. The single motor drives the double screw sleeves to move, which simplifies the structure while ensuring the action coherence, simplifies the operation steps, and improves the automation operation efficiency and mechanical reliability.

[0017] 3. The computer hard disk protection and transfer device provided by the present invention compresses the occupied lateral space and supports multi-layer dense arrangement through the staggered layout of screws and the centralized installation of drive motors; each layer of storage unit is independently controlled, and specific compartments can be unfolded as needed, taking into account the requirements of high-density storage and flexible access, and improving the space utilization rate by more than 30%.

[0018] 4. When the unfolding box of the computer hard disk protection and transfer device provided by the present invention is laid flat and folded, the hard disk baffle forms a dynamic sealing barrier with the top airbag through the support airbag, eliminating the shaking of the hard disk; the integrated control panel supports one-key operation, reducing the risk of manual operation, and taking into account both the protection strength and the convenience of use; the communication compensation function between airbags can automatically wrap and fix the hard disk to form an all-round protection.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment 1: This embodiment provides a computer hard disk protection transport device, such as Figures 1-10 As shown, it includes a cabinet frame 2 fixed on a 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, which is convenient for 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.

[0023] like Figures 3-9 As shown, the storage unit 3 includes a folding box 4, a hard disk baffle 5, a slide plate 6, a torsion spring 31, an folding drive mechanism 7 and a retracting drive mechanism 8. The slide plate 6 is installed on the bottom of the storage cavity along a transverse sliding manner and is connected to the retracting drive mechanism. The retracting drive mechanism is connected to a control unit. The bottom of the folding box is hingedly installed on the slide plate. The control unit can drive the slide plate 6 to drive the folding box to slide outward along the transverse direction through the retracting drive mechanism, and extend the cabinet frame 2 through the opening on the same side.

[0024] There are many ways to install the slide plate 6. For example, a plurality of slide rails are provided at longitudinal parallel intervals at the bottom of the storage cavity on the inner side of the opening. An anti-slip slider is installed in the slide rail. The anti-slip slider is fixedly connected to the bottom of the slide plate. When the slide plate 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 out of the cabinet frame 2.

[0025] like Figure 7As shown, the retracting and extending driving mechanism 8 includes a driving component and an active cylinder 83, a driving component and a control unit, and the driving component can push the slide plate 6 outward through the active cylinder 83; the driving component includes a screw 81, the screw 81 is arranged along the longitudinal direction, 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 with a driving motor, and the driving motor is connected to the control unit, and the control unit controls the driving 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 arranged in opposite directions, and the inner end of the slide plate between the two screw sleeves 82 is longitudinally Two active cylinders 83 are 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, and 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 rod is driven to rotate, the two screw sleeves will move towards each other or move away from each other in opposite directions following the rotation of the screw rod 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 top slide. 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 slide.

[0026] In the computer hard disk protection and transportation 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, and a device box 22 is fixedly installed on the front side of the cabinet frame. The drive motor is fixedly installed in the device box, and the screw extends into the device box to be transmission-connected with the corresponding drive motor. By alternately arranging the screws up and down, the installation space required for the two storage units can be effectively reduced.

[0027] A plurality of hard disk slots 41 are evenly spaced longitudinally inside the flip box 4 for inserting the hard disk 9. An inner protective component is provided in the hard disk slot, and the inner 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. The bottom air bag is in a normally expanded state. In the present embodiment, the bottom air bag 42 is a corrugated tube-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.

[0028] A flip groove 61 is parallelly arranged on the slide plate 6 outside the flip box 4, a rotating shaft 62 is rotatably installed in the flip groove 61, the hard disk baffle 5 is fixedly sleeved on the rotating shaft, the top of the hard disk baffle extends upward, and a buffer is fixed, and the buffer is located on the end surface of the hard disk baffle facing the flip box 4. In this embodiment, the buffer includes a plurality of top airbags 51 arranged at intervals in the longitudinal direction, the top airbags are fixed to one end of the hard disk baffle facing the flip box above the rotating shaft, and the top airbags correspond to the hard disk slots one by one.

[0029] The slide plates 6 on the left and right sides of the flip box 4 are symmetrically provided with driving grooves 63 connected to the flip grooves. The flip driving mechanism 7 includes a slave cylinder 71 fixed in the driving grooves in the transverse direction. The slave cylinders 71 are installed in both driving grooves 63. The slave cylinders 71 are connected to the active cylinder 83 through oil pipes. The telescopic ends of the slave cylinders 71 are arranged toward the flip grooves and are hinged with support rods 72. There are many ways to hinge the support rods 72, for example: a connecting block 73 is fixedly installed at the telescopic end of the slave cylinder, a fixed shaft is provided on the connecting block 73, and the bottom end of the support rod 72 is rotatably sleeved on the fixed shaft. The left and right end surfaces of the flip box are symmetrically and slidably installed with slides 74. There are many ways to install the slides 74, for example: the slides 74 are matched and mounted on the guide rails 75, and the guide rails 75 are fixedly installed on the flip box; the top of the support rod is hinged to the slide on the same side. When the flip box is flipped around the bottom end and laid 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 driving component, the driving component 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 linkage, thereby driving the flip box to flip and lift around the bottom end.

[0030] 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 slide outward to the limit length through the active oil cylinder push-up slide plate, 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 seat to slide toward the bottom of the flip box, and after the slide seat slides to the limit position, driving the flip box to flip and lift around the bottom end.

[0031] Further, a negative pressure compensator 86 is connected to 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 driven oil cylinder, and a positive pressure compensator 87 is connected to 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 driven oil cylinder. The negative pressure compensator 86 includes a negative pressure compensating cylinder body 861 communicated with the oil pipe. A negative pressure piston 862 is fitted and installed in the negative pressure compensating cylinder body 861, and a top spring a 863 is fitted and installed in the cylinder body above the negative pressure piston 862. In the natural state, the top spring a pushes the negative pressure piston to move towards the cylinder bottom, 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, the hydraulic oil in the piston cavity at the tail of the driven oil cylinder is sucked, and the active oil cylinder 83 will synchronously suck the hydraulic oil in the negative pressure compensator for volume compensation. The positive pressure compensator 87 includes a positive pressure compensating cylinder body 871 communicated with the oil pipe. A positive pressure piston 872 is fitted and installed in the positive pressure compensating cylinder body, and a top spring b 873 is fitted and installed in the cylinder body below the positive pressure piston. In the natural state, the top spring b pushes the negative pressure piston to move towards the cylinder top. When the telescopic end of the active oil cylinder 83 retracts into the cylinder barrel, the hydraulic oil pressure in the piston cavity at the tail of the active oil cylinder 83 is discharged into the piston cavity at the top of the driven piston. The excess hydraulic oil due to different volumes will be discharged into the positive pressure compensator for volume compensation.

[0032] The torsion spring is installed between the rotating shaft and the flipping groove. When the unfolding box rotates around the bottom end and lies flat on the sliding plate, the telescopic end of the driven oil cylinder continues to extend, which will push the hard disk baffle below the rotating shaft to flip around the rotating shaft, thus twisting the torsion spring and driving the buffer member to push the hard disk into the hard disk slot. During this process, the telescopic end of the driven oil cylinder will drive the sliding seat to slide towards the top of the unfolding box through the support rod 72, so that after the unfolding box rotates around the bottom end and lies flat on the sliding plate, the driven oil cylinder still has an extension margin.

[0033] Specifically: such as Figure 8 and Figure 9As shown, torsion springs 31 are installed in the flipping grooves 61 on the left and right sides of the hard disk baffle 5. The torsion springs 31 are sleeved on the corresponding rotating shafts in a matching manner. The two ends of the torsion springs 31 respectively abut against the inner wall of the hard disk baffle 5 and the flipping groove 61. In the natural state, the torsion springs 31 drive the hard disk baffle 5 to rotate away from the unfolding box. A support airbag 52 is provided between the hard disk baffle 5 below the rotating shaft and the driven oil cylinder. A cavity is provided in the slide plate 6 between the two driving grooves 63. The cavity is respectively communicated with the two side driving grooves 63 and the flipping groove 61. A connecting plate 84 is provided in the cavity. The two ends of the connecting plate are respectively fixedly connected to the telescopic ends of the driven oil cylinders in the two side driving grooves. When the telescopic ends of the driven oil cylinders extend and retract, the connecting plate is driven to move synchronously along the cavity, approaching or departing from the flipping groove. The support airbag 52 is fixedly installed on the end face of the connecting plate facing the flipping groove side. The support airbag 52 is in a constantly inflated state. In this embodiment, the support airbag 52 is a corrugated airbag. The support airbag is communicated with each top airbag. When the unfolding box rotates around the bottom end and lies flat on the slide plate, the continuous extension of the telescopic end of the driven oil cylinder will push the baffle to turn and stand upright around the rotating shaft through the support airbag, and squeeze the support airbag to drive each top airbag 51 to expand and push the hard disk into the hard disk slot.

[0034] The control unit includes a controller and a control panel. The controller is connected to the control motors of each unfolding and folding drive mechanism and identifies the control motors of each unfolding and folding drive mechanism. The control panel is connected to the controller. The control panel is installed on the device box 22. Through the control panel, the extension and unfolding and the folding and retraction of the corresponding storage unit can be selectively controlled.

[0035] When the computer hard disk protection and transfer device provided by this embodiment is in use, according to the requirements, the required storage unit is selected and controlled through the control panel to automatically extend and unfold. After the slide plate of the storage unit completely extends out of the frame with the flipping box, the retracting and extending drive mechanism drives the two driven oil cylinders of the flipping drive mechanism. The retraction of the telescopic ends of the driven oil cylinders drives the slide seat to move towards the bottom of the flipping box. After the slide seat moves to the limit position, it drives the flipping box to flip and lift around the bottom end, so as to facilitate the operator to take and place the hard disk. During the movement of the slide seat, the hard disk baffle will lose its block and drive the buffer member to avoid the flipping box by rotating around the rotating shaft under the drive of the torsion spring. After the hard disk is inserted, the storage unit is selected and controlled through the control panel to automatically retract and fold; at this time, the controller controls the screw of the retracting and extending drive mechanism of the storage unit to rotate in the reverse direction. The reversely rotating screw drives the two screw sleeves to move away from each other in opposite directions. The telescopic ends of the two active oil cylinders first extend and reset under the action of the compressed top spring, so as to drive the telescopic ends of the two driven oil cylinders to extend out and reset synchronously. During this process, the lifted flipping box will first rotate around the bottom end and lie flat on the slide plate; when the flipping box lies flat on the slide plate, the telescopic end of the driven oil cylinder pulls the slide seat to move and reset towards the top side of the flipping box. At the same time, the telescopic end of the driven oil cylinder will continue to extend and push the supporting airbag. The supporting airbag drives the hard disk baffle to flip around the rotating shaft; the driven oil cylinder continuously extends and squeezes the supporting airbag, driving each top airbag 51 to expand and push the hard disk into the hard disk slot; when the hard disk is pushed, the hard disk will squeeze the bottom airbag 42, causing the bottom airbag 42 to discharge part of the gas into each annular airbag 43 in the airbag ring group, causing the annular airbag 43 to expand, and realizing the all-round wrapping protection of the corresponding hard disk through the bottom airbag, annular airbag and top airbag; after the slide seat moves and resets towards the top side of the flipping box, as the screw continues to rotate, the two screw sleeves drive the slide plate to retract inward through the two active oil cylinders, driving the lying flat flipping box to retract into the frame.

[0036] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principles of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
