Fig. 2 is that the functional structure of the USB flash disk compatible that provided of the utility model embodiment is formed synoptic diagram.
Embodiment
Referring to Fig. 1, the entity structure synoptic diagram of the USB flash disk compatible that is provided for the utility model embodiment.It comprises the compatible joint 3 of USB flash disk compatible body 1 and USB joint or USB.
The compatible joint 3 of described USB joint or USB joins with an end face of USB flash disk compatible body 1.Wherein, be equiped with on master control borad 12, the described master control borad 12 in the described USB flash disk compatible body 1 on the card insert bowl assembly 124 that is equiped with main control chip 122, is used to put card, the master control borad 12 and be equiped with flash memory control chip 52 and flash chip 54, described main control chip 122 is electrically connected with USB joint or the compatible joint 3 of USB, card insert bowl assembly 124 and described flash memory control chip 52 respectively, and described flash memory control chip 52 is electrically connected with described flash chip 54.
Described card insert bowl assembly 124 comprises a slot 1242, slot 1242 has groove is put card as USB flash disk compatible body 1 passage, card (comprising smart card and storage card) inserts described slot 1242 backs and is electrically connected with described main control chip 122, makes the USB flash disk compatible realize the function that card reader had.
Further, the functional structure of the USB flash disk compatible that provided for the utility model embodiment of Fig. 2 is formed synoptic diagram.
As shown in Figure 2, main control chip 122 is electrically connected with the compatible joint 3 of USB joint or USB, card insert bowl assembly 124, flash memory control chip 52 respectively, and flash memory control chip 52 is electrically connected with described flash chip 54.Main control chip 122 writes data by the control to flash memory control chip 52 in flash chip 54, or reads the data of storage in the described flash chip 54, makes this USB flash disk compatible realize the function of similar USB flash disk.
Described main control chip 122 comprises: be used for main control unit 1222 that the card (comprising smart card and storage card) that inserts described draw-in groove 1242 and flash memory control chip 52 are controlled.Computing machine also can write data to controlling in flash chip 54 of flash memory control chip 52 when controlling the information content that reads in the card (comprising smart card and storage card) that inserts on the card insert bowl assembly 124 by main control unit on the main control chip 122 1222, or reads the data of storage in the described flash chip 54.
Below in conjunction with Fig. 1, Fig. 2 storage of USB flash disk compatible and the embodiment that reads informational function are described: because of connecting flash memory control chip 52 on the main control chip 122 of USB flash disk compatible master control borad 12, flash memory control chip 52 is connected with flash chip 54 again, when the USB flash disk compatible is connected with computing machine, computing machine writes data by the control of 1222 pairs of flash memory control chips 52 of main control unit on the main control chip 122 in flash chip 54, or storing data information on the flash chip 54 is read.What deserves to be explained is that flash memory control chip 52 is complementary with the type of flash chip 54, in the specific implementation, described flash memory control chip 52 can comprise the flash memory control chip of CF card, SD card, SM card, mmc card and Sony's memory stick etc.
With flash memory control chip 52 is that the flash memory control chip of SD card is an example, illustrates that the USB flash disk compatible is realized data storage and the embodiment of the function that reads.At first, USB flash disk compatible USB joint or the compatible joint 3 of USB are connected with main frame, control by 1222 pairs of flash memory control chips 52 of main control unit on the main control chip 122, computing machine can write data in flash chip 54, or read the data of storage in the described flash chip 54, and corresponding, show that on computers the USB flash disk compatible coils pair accordingly, for example: " G " dish, the user can operation such as change to the information (the both information of flash chip 54 stored) in " G " dish.
Among another embodiment of the present utility model, when needs use the USB flash disk compatible that the information of card (comprising smart card and storage card) is read, promptly realize USB flash disk compatible functions of card reader, card can be inserted in the slot 1242 on the card insert bowl assembly 124, the USB joint or the compatible joint 3 of USB that are seated behind the card the USB flash disk compatible are connected with computing machine, after setting up being electrically connected of USB flash disk compatible and computing machine, under the control of main control chip 122 main control units 1222, computing machine reads the information content in the card that inserts on the card insert bowl assembly 124, and show the corresponding drive of USB flash disk compatible on computers, for example: " H " dish, the user can change the information (both card in information) in " H " dish and wait operation, this USB flash disk compatible to realize by the card insert bowl assembly 124 on the USB flash disk compatible body 1 and the common card reader identical functions of sale on the market.
Be understandable that, when card inserts in the slot 1242 on the card insert bowl assembly 124, also can control when reading card image under the control of computing machine main control unit 1222 on main control chip 122 flash memory control chip 52, read canned data on the flash chip 54, make the USB flash disk compatible realize the function of similar USB flash disk, when computing machine reads, show corresponding two drives on computers, for example: " G " dish, " H " dish, wherein, canned data in the flash chip 54 that " G " dish is with master control borad 12 is connected, " H " dish are the interior information of card that the USB flash disk compatible inserts.
