Detailed ways

The above-mentioned and other technical features and advantages of the present utility model will be described in more detail below in conjunction with the accompanying drawings.

Please refer to FIG. 2 to FIG. 4 , which are schematic diagrams of preferred embodiments of the present invention. The embodiment of the utility model is that a storage device is provided with a hard disk access device having the effect of protecting data and power failure buffering. In this embodiment, the storage device is a disk array system, which includes a housing 10, and the housing 10 is provided with a plurality of extractable hard disk extraction boxes 20, each for accommodating and fixing a hard disk 40 ; each hard disk extraction box 20 is equipped with a hard disk entry and exit device 30 . The hard disk access device 30 includes a knob 31 and a switch element 32, the knob 31 is movably and fixedly arranged on the hard disk extraction box 20, and is used to withdraw the hard disk extraction box 20 from the housing 10 to take out the hard disk; the switch element 32 , arranged on one side of the hard disk extraction box 20 in the housing 10 , and detecting whether the hard disk extraction box 20 is withdrawn.

The hard disk extraction box 20 has a chassis 21, the front end of the chassis 21 is provided with a panel 22, a hard disk is locked on the chassis 21, and the rear end of the hard disk has a SATA (Serial AT Embedded Interface) connection interface . Described knob 31 is located at an end of described panel 22, and described knob 31 has a screw rod 311; Described screw rod 311 is provided with a swivel head 312 at the front end, and described screw rod 311 is positioned at the inner side of described panel 22; 312 is located on the outer side of the panel 22 for rotation operation. The knob 31 is movably fixed on the panel 22, and can only freely rotate over 360 degrees on the panel 22, so that the hard disk extraction box 20 can be rotated into the housing 10 to complete the installation. Connect, or withdraw from the casing 10, and separate from the casing 10, so as to load and unload the hard disk. The casing 10 is provided with a sliding slot 11 for inserting the chassis 21 of the hard disk extraction box 20 . A screw hole 12 is provided at a position corresponding to the screw rod 311 of the knob 31 for the screw rod 311 to be screwed in so as to drive the hard disk extraction box 20 to withdraw slowly by turning the knob 31 .

The switch element 32 is arranged on one side of the hard disk extraction box 20 in the housing 10, and is located on the rear side of the panel 22 relative to the other end of the knob 31, and detects the movement of the panel 22, through Detect the movement of the panel 22 to detect whether the hard disk extraction box 20 is withdrawn. The switch element 32 can be a proximity switch. When the hard disk extraction box 20 withdraws from the sensing distance beyond the proximity switch by rotating the knob 31, the proximity switch sends a control signal to the control unit (not shown) of the computer to close the Hard disk power operation and data storage protection, and then the hard disk extraction box is completely withdrawn, so as to achieve the effect of perfect data protection and power-off buffering.

The panel 22 of the hard disk extraction box 20 is also provided with an indicator light 23 for status display. When the switch element 32 sends a control signal to notify the control unit of the computer to extract the hard disk, the control unit performs data storage protection and Turn off the power supply of the hard disk, and when the above actions are completed, the indicator light 23 will light up, indicating that the hard disk can be taken out safely.

At least two hard disk extraction boxes 20 are respectively provided with a plurality of in-line cooling holes 24 on the panel 22, and the rear end of the top surface of the housing 10 of the storage device is also provided with a plurality of in-line cooling holes 13, thereby enhancing air convection , so that the heat dissipation effect is better, and the temperature difference between the upper and lower hard drives can be reduced.

Through the above structure, the hard disk access device described in the embodiment of the present invention has the effect of buffering power failure. When the hard disk is to be taken out, the knob 31 on the rotating panel 22 is screwed out of the screw hole through the screw rod 311 12. Simultaneously drive the hard disk extraction box 20 to exit. This spiral rotation method makes the hard disk withdraw slowly, which can prevent the hard disk from being pulled out suddenly, which may cause transmission interruption and data loss. After the knob 31 rotates about three or four times, the panel 22 of the hard disk extraction box 20 also withdraws from the detection distance of the switch element 32. At this time, the connection interface at the rear end of the hard disk has not been completely disengaged, and is still in the connected state. , and the switch element 32 immediately sends a control signal to the control unit of the computer, notifying the control unit that the hard disk is in the exit state, so that the control unit can have a buffer time for data storage protection, and then close the hard disk. power supply. After the above-mentioned protection action is completed, the indicator light lights up to inform the user that the hard disk extraction box can be safely taken out. Afterwards, the hard disk extraction box 20 continues to withdraw, and when the screw rod 311 of the knob 31 leaves the screw hole 12 of the housing 10, the hard disk connection interface is completely disengaged.

Therefore, through the spiral withdrawal method, if the user accidentally pulls out the hard disk or pulls out the wrong hard disk, the transmission will not be interrupted due to rapid and sudden withdrawal; and when withdrawing, through the detection of the switch element, it can Protect the data first and then turn off the power to exit the hard disk, so as to perfectly protect the data, maintain the integrity of the data during the transmission process, and protect the hard disk from being damaged due to sudden power failure.

The above description is only illustrative of the present utility model, rather than restrictive. Those of ordinary skill in the art understand that many modifications and changes can be made without departing from the spirit and scope defined by the following appended claims. , or equivalent, but all will fall within the protection scope of the present utility model.
