Embodiment
Below in conjunction with Figure of description, embodiments of the present invention are described.
As shown in Figure 1, the present invention has designed a kind of portable hard drive based on expansion type, comprise housing 1 and be arranged at control circuit board 2, the memory interface 4 on housing 1, wherein said control circuit board 2 comprises memory storage 3, and memory storage 3 is controlled by control circuit board 2; Also comprise the extended interface 5 and the independent hard disk 6 that are arranged at housing 1 surface, wherein said extended interface 5 is connected with control circuit board 2; When described independent hard disk 6 is connected with extended interface 5, and the internal memory of the internal memory of independent hard disk 6 and memory storage 3 is all controlled and is stored for control circuit board 2, now control circuit board 2 can be arranged the space of the memory storage of self 3, can also arrange the space of the independent hard disk 6 inserting, prop up timing can point priority level, as being arranged to first memory storage 3 to be used, in the time that the internal memory of memory storage 3 is finished, restart the use of the internal memory to independent hard disk 6; In the time that described independent hard disk 6 disconnects with extended interface 5, control circuit board 2 can only be controlled the internal memory of memory storage 3 is used, and now the internal memory of independent hard disk 6 is independently stored, thus, make independent hard disk 6 as a storage medium independently, realize the function of itself.In force, memory size that can be as required, selects the quantity of the independent hard disk 6 of extended interface 5 quantity that arrange and connection, reaches thus the problem that expands as required portable hard drive capacity.
In addition, be provided with groove 7 on housing 1 surface, described extended interface 5 is arranged on the sidewall of groove 7, make after independent hard disk 6 inserts extended interface 5, can integrate with housing 1 less taking up space, further make the connection of independent hard disk 6 more stable, be convenient for carrying.Due to storage medium conventional be USB interface, extended interface 5 can be preferably USB interface thus, like this, can make can be general being connected into for independent hard disk 6.
And, further consider the security of portable hard drive, add fingerprint identification function, portable hard drive also comprises fingerprint capturer 8 and Fingerprint Identification Unit 9, wherein fingerprint capturer 8 is arranged at housing 1 surface; Described fingerprint capturer 8 is connected with Fingerprint Identification Unit 9; Described Fingerprint Identification Unit 9 is connected with control circuit board 2; In the time that portable hard drive utilizes the memory interface 4 of self to connect data line output or deposited data in, first identity is verified, gather fingerprint by fingerprint capturer 8, then identify fingerprint by Fingerprint Identification Unit 9 and send into control circuit board 2, control circuit board 2 and the finger print information coupling pre-depositing, the match is successful allows the transmission of data in hard disk again.Make to verify by fingerprint recognition before data are transmitted, strengthened the security of portable hard drive, ensured data transmission authentication before.
In addition, due to traditional portable hard drive cannot displaying contents service condition, therefore hard disk of the present invention also comprise connected successively power supply 10, switch 11, for showing the display screen 12 of storing consumption, wherein said display screen 12 is connected with control circuit board 2, after Push switch 11, control circuit board 2 can Real-time Obtaining self internal memory service condition, then control display screen 12 and demonstrate consumption or free memory size, be convenient to the service condition that user directly grasps hard disk, need not be connected into computer and just can know its consumption.
One embodiment of the invention are as follows, comprise that taking portable hard drive two extended interfaces 5 and independent hard disk 6 are as example, as shown in Figure 1, first, in the time that needs expand hard disk, two independent hard disks 6 are inserted respectively to extended interface 5, the now internal memory of control circuit board 2 free memory storeies 3 and the internal memory of two independent hard disks 6, and the preferably internal memory of choice for use memory storage 3, it selects the internal memory with independent hard disk 6 again after having expired, between two storage spaces, be separate, the internal memory of two independent hard disks 6 is also applied in the storing process of data thus; In the time that data are called, connect data line by memory interface 4, before data line is handed down from ancient times, user puts into fingerprint capturer 8 by finger and gathers fingerprint, Fingerprint Identification Unit 9 identifies fingerprint and sends into control circuit board 2, control circuit board 2 and the finger print information coupling pre-depositing, the match is successful allows the transmission of data in hard disk again, completes thus identification.Need to check the internal memory situation of hard disk time, can Push switch 11, display screen 12 is directly by consumption and free memory amount show.
And in the time that needs independently use independent hard disk 6, as shown in Figure 2, two independent hard disks 6 disconnect with extended interface 5 respectively, now the data of two independent hard disk 6 original storages can still be kept at wherein, and remaining internal memory can also offer storage.Make independent hard disk 6 as a storage medium independently, realize the function of itself.
Therefore, the present invention makes improvement on the whole by the portable hard drive to traditional, make improve after portable hard drive in the time possessing expandability, can also further improve the security of data transmission, thus, can offer more easily user use.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, makes a variety of changes.
