Description
[technical field]
The relevant a kind of hard disk converter of the present invention, especially a kind of hard switching device that when receiving the disk read-write instruction, just drives the hard disk action.
[background technology]
In the maintenance and testing process of notebook computer, the situation of hard disk corruptions often occurs, and the hard disk price of notebook computer is expensive partially, the hard disk that if can convert notebook computer with the hard disk of more cheap desktop computer to uses, and will save cost.
Existing hard disk connector, at least be provided with the interface slot of two kinds of standards, hard disk chip in order at least two kinds of standards of pegging graft, realize the mutual conversion between each hard disk, but these hard disk connectors adopt generally the ATX power supply to power to hard disk, even and when shutdown, the also thoroughly not isolated electric current output of ATX power supply itself, but kept a fainter electric current, hard disk can be worked always like this, has shortened the life-span of hard disk and has also wasted the energy.
In view of this, be necessary to provide a kind of hard disk adapting receiving apparatus in fact, realize the conversion of the hard disk of different specification, and only when receiving the disk read-write instruction, just drive the hard disk action.
[summary of the invention]
Therefore, purpose of the present invention promptly provides a kind of hard disk converter, is one to be installed in the hard disk in the electronic installation in order to change an external hard drive, and only just drives this external hard drive action when receiving the disk read-write instruction.
For reaching above-mentioned purpose, the invention provides a kind of hard disk converter, be coupled between above-mentioned external hard drive and the above-mentioned electronic installation, it is powered with an external power supply, and comprise two interfaces at least, be connected with above-mentioned external hard drive and the hard disk that is installed in the electronic installation respectively; Again, comprise that also a voltage conversion circuit connects above-mentioned external power supply, the supply voltage of changing this external power supply is for being fit to the supply voltage of this hard disk converter, and one drive circuit connect this voltage conversion circuit and above-mentioned interface one of them, down for being coupled to the external hard drive power supply of this interface, and then this external hard drive done data are read, write activity in the control of the disk read-write of this electronic installation instruction.
Compared with prior art, the present invention utilizes driving circuit to power for external hard drive in disk read-write when instruction that receives electronic installation, so this electronic installation to these external hard drive data read, write activity, reach purpose of the present invention.
[description of drawings]
Fig. 1 is the structured flowchart of a preferred embodiment of hard disk converter of the present invention.
[embodiment]
Consult Fig. 1, structured flowchart for a preferred embodiment of hard disk converter of the present invention, hard disk converter 10 of the present invention is coupled between one first hard disk 20 and the electronic installation 31, in order to this first hard disk 20 is converted to second hard disk 30 that is installed in this electronic installation 31, wherein, this hard disk converter 10 is its power supply with an external power supply 40.Again, this hard disk converter 10 comprises first at least, second interface 11,12, respectively with above-mentioned first, second hard disk 20,30 connect, in the present embodiment, this is first years old, second hard disk 20,30 is the hard disk chip of tool different specification, for example this first, second hard disk 20,30 are respectively 40 pins (Pin), the hard disk chip of the desktop computer of 44 pins and notebook computer, and this is first years old, second interface 11,12 is the slot on the printed circuit board (PCB) of corresponding above-mentioned hard disk chip, and this is first years old, second interface 11, signal lead layer by printed circuit board (PCB) between 12 carries out data transfer, and this external power supply 40 is the power supply adaptor of notebook computer, in order to civil power alternating voltage (as 220V) is converted to low-voltage DC (as 19V).
This hard disk converter 10 also comprises voltage conversion circuit 13, driving circuit 14, wherein this voltage conversion circuit 13 is connected with above-mentioned external power supply 40, its low-voltage dc voltage that this external power supply 40 is provided in the mode of width modulation (PWM) is converted to the supply voltage that is fit to this hard disk converter 10, be the 5V supply voltage of variation range about ± 2% in ± 10% 19V voltage transitions for example, promptly carry out the action of voltage stabilizing and power amplification variation range; Again, this driving circuit 14 couples the above-mentioned voltage conversion circuit 13 and first interface 11 respectively, be this first hard disk, 20 power supplies, preferably, this driving circuit 14 is coupled on the signal display unit 15 between this first, second interface 11,12, wherein this signal display unit 15 is in order to the transmission status between the display electronics assemblies 31 and first hard disk 20, and it can be embodied as corresponding to the signal testing point of each hard disk chip pin and light emitting diode (LED).When the instruction of the disk read-write of electronic installation 31 exports driving circuit 14 to by second interface 12, signal display unit 15,14 of this driving circuits are 20 power supplies of first hard disk by signal display unit 15, first interface 11, and data be read or be write to this electronic installation 31 can by second, first interface 12,11 simultaneously from this first hard disk 20.
In addition; this hard disk converter also comprises an over-voltage over-current protection circuit 16; be coupled to above-mentioned voltage conversion circuit 13, in order to limiting the supply voltage that external power supply 40 provides in order to avoid surpass rated voltage, and restriction exports the electric current of second hard disk 12 in safe range.
In the practical application, this first, second hard disk 20,30 is embodied as the different hard disk of several interfaces, as notebook computer hard disk chip, desktop computer hard disk chip, mobile hard disc box, SATA hard disk etc., correspondingly, this first, second interface 11,12 is embodied as and the slot that mates such as notebook computer hard disk chip, desktop computer hard disk chip, mobile hard disc box, SATA hard disk etc., and be connected with data line between these slots and these hard disks, and these slots couple with signal display unit 15 respectively.
Compared to prior art, it is first hard disk and signal display unit power supply when the disk read-write instruction that receives electronic installation that the present invention utilizes driving circuit, and then this electronic installation does the action of reading, write data to this first hard disk, reaches purpose of the present invention; Can be convenient to maintenance and detect by learn the break-make situation between the electronic installation and first hard disk such as the different conditions of signal display units such as signal testing point and light emitting diode simultaneously.
