Description

The storage device of tool power-off protection function and control joint

Technical field

The utility model relates to a kind of storage device, refers to a kind of storage device with a sensing cell and a switch especially, and it can promptly close the storage device of the tool power-off protection function of its power supply behind the movement value that receives this sensing cell.

Background technology

The Portable hard disk is can be by being coupled to a main frame by a connector with its content of access, and only hard disk is a kind of very accurate storage device, and casual collision or drop all might destroy its stored content, even cause nonvolatil destruction.Therefore, general existing Portable hard disk has protection mechanism usually, to protect this Portable hard disk when colliding, shaking or dropping, can alleviate suffered injury.

The for example approved U.S. the 5th; 227; (its applying date is November 26 nineteen ninety to No. 929 patents; checking and approving day is on July 13rd, 1993); promptly disclose a kind of protective reaction system of portable computer hard disk; it has a three-dimensional accelerometer (3D accelerometer); one application specific processor; one General Porcess Unit and a Winchester disk drive; sense when this three-dimensional accelerometer and to send a signal to this application specific processor when this Winchester disk drive is dropped; this application specific processor is sent the look-at-me of a high priority again to this General Porcess Unit, and this General Porcess Unit is carried out the brake (break) of read/write head to this Winchester disk drive again or stopped the action of (park).Only this patent case needs three-dimensional acceleration to take into account application specific processor, and cost is higher, and the function that has automatic brake or stop when outage of hard disk now, so this patent case and can't meet the demand of Winchester disk drive now.

(its applying date is on 02 01st, 2005 to No. 275509 novel patent in for example approved again Taiwan, the day for announcing is on 09 11st, 2005), promptly disclose a kind of read-write medium of tool external impacts sensing protection mechanism, it is the suffered external impacts of sensing device for reading-writing media, calculate the also status information of recording external force impact, it comprises at least: a sensing cell is in order to detecting an external force, and transmits the external power signal that detects to signal computing unit; One signal computing unit, be in order to calculate the numerical value of external force, when external force greater than the default critical point of mechanism, and transmit a bump signal and write down the user mode of device for reading-writing media protection mechanism to notify CPU (central processing unit), status information with external impacts is recorded in a record cell simultaneously, and send the user mode of a recovering signal with notice CPU (central processing unit) recovery device for reading-writing media protection mechanism when external force removes Shi Zehui, handle different incidents respectively and then be sent to different unit; One record cell provides this status information that this first arithmetic element record is subjected to external impacts; One read-write media units is to be the unit in order to store and to read and write data in this device for reading-writing media; One CPU (central processing unit), be that signal Processing also writes down the state that uses with reduction device for reading-writing media protection mechanism in the device for reading-writing media protection mechanism in order to handle, when receiving the bump signal, write down the state of use and force power down process, and when receiving recovering signal, the state that the device for reading-writing media protection mechanism of then reducing is used; And a sensing susceptibility adjustment unit, be in order to adjusting this machine-processed susceptibility, and can see through the susceptibility that the user adjust sensing voluntarily, make the different users adjust the sensing susceptibility that it needs, and the multiple responsive level of definable.Only this patent case needs signal computing unit, record cell and a sensing susceptibility adjustment unit, and cost is higher.

(its applying date is on 02 01st, 2005 to No. 281266 novel patent of for example approved again TaiWan, China, the day for announcing is on November 21st, 2005), promptly disclose a kind of protection mechanism of signal conditioning package application of external read-write medium, be to see through a communication interface by circumscribed read-write medium to be plugged in when operating on the signal conditioning package, in order to guarantee when being subjected to external force collision, reduce its suffered loss, wherein, these circumscribed read-write medium comprise at least: a detecting unit, be to be connected to a signal processing unit, in order to detect an external force, and the numerical value of this external force and a default critical value compared, if greater than this critical value, promptly send a bump signal, and send a recovering signal when external force removes Shi Zehui, handle different incidents respectively and then be sent to different unit; One signal processing unit, be to see through the CPU (central processing unit) that this communication interface is connected to this signal conditioning package, when receiving this bump signal, it sends a power-off signal, and when receiving this recovering signal, send a return signal, handle different incidents respectively and then be sent to different unit; One external media units is to store and the unit that reads and writes data for providing in these circumscribed read-write medium; And a power supply unit, be in order to the power supply of these read-write medium to be provided.This patent case of thought still needs signal computing unit, power supply unit, electric energy control unit and discharges and recharges the assembly of function, and cost is higher, really belongs to a fly in the ointment.In addition; its power supply unit and electric energy control unit still can provide electric power to read and write medium to this after losing power supply; it causes that easily the read-write medium still have the erroneous judgement of power supply; and then can't enter power-down mode (Non-operationMode); that is can't reach the automatic protection mechanism of outage (Auto Park mechanism or Load/Unload mechanism) of reading and writing medium, can't protect this read-write medium.
