Abstract

The utility model discloses a USB double interface portable disc, and especially a USB interface module which can access data with a computer and peripheral equipment thereof, wherein the interface is simultaneously provided with two interfaces of a standard type USB and a mini USB and is formed from the combination of a USB control chip and single or more quick flash memory chip. Therefore, the utility model is indeed suitable for operating requirements of the size of the double interfaces and conforms with data access of transmission interfaces with different specifications.

Description

The carry-on dish of USB double nip

Technical field

The utility model relates to the carry-on dish of a kind of USB double nip, refers to especially store the device of getting in order to the funding material.

Background technology

Along with Science and Technology Day reaches increasingly, media products such as associated electrical information products such as PC, MP3, digital camera/Video Camera are universal, and the consumer is used for doing the also increase gradually of device demand of digital storage with respect to using these multimedia commodity, but these storage devices also have its different specification size device along with the difference of appropriate products.

With at present, USB interface has almost become the standard interface of computer and interfacing equipment, select for use the carry-on dish (claiming thumb again) of USB interface to we can say almost and can reach available purpose everywhere, add that USB interface also possesses plug and play, the characteristic of hot plug, concerning the user, also can save the puzzlement of repetition install driver, and because these storage devices have gently, thin, short, little, characteristics such as easy to carry, this storage device system utilizes flash memory (Flash, TaiWan, China is referred to as fast flash memory bank/card), and reach the effect that the storage of high power capacity data is got, thereby replace bulky traditional soft gradually, hard disk.

But owing to have the carry-on dish 100 (as shown in Figure 3) of single transmission interface, only can carry out data transmission (as standard form USB 200 interfaces) by the corresponding interface that is suitable for single specification, thereby can't be suitable for other form or specification interface again, cause it to use and show inconvenience when going up, though in the streets there is the dealer to utilize USB interface to combine with CF transmission interface (the CF card of 50Pin), to attempt to reach the data storage that double nip uses, as the novel patent announcement of TaiWan, China No. 572284 " improvement of memory card structure ", No. 551552 " two interface CF card ", but because the CF interface is to be the specific use of CF card, non-ly generally be applicable to general now USB interface, thereby the regret of the ideal of not attaining is arranged.

The built-in USB interface of present common computer peripheral equipment series such as Mini USB are still arranged, yet existing digital machine only is furnished with a kind of transmission interface usually except standard stencillings such as 1.1,2.0, therefore also often off-gauge takes place and the awkward situation that can't use.

The utility model content

The purpose of this utility model is to provide a kind of carry-on dish of USB double nip that has standard form USB and MiniUSB interface simultaneously, uses to be suitable for the double nip specification.

For achieving the above object, technical solution of the present utility model is: the carry-on dish of a kind of USB double nip is respectively equipped with standard form USB interface and Mini USB interface on this carry-on dish.

The circuit of this control double nip is that the USB control chip forms in conjunction with single or many fast-flash memory chip portfolios.

This standard form USB is connected on the USB control chip for design in parallel with Mini USB double nip.

This standard form USB interface and Mini USB interface are arranged at carry-on dish two ends or same end or the same side or homonymy not respectively.

After adopting such scheme, because carry-on dish described in the utility model has standard form USB and two kinds of interfaces of Mini USB simultaneously, so it has the request for utilization of suitable double nip specification really, to meet the transmission interface data access of different size.

In addition, this the utility model utilizes a USB control chip to form in conjunction with single or many fast-flash memory chip portfolios, and this USB control chip, line design are parallel telling standard form and Mini USB joint, thereby can the situation that cause another kind of interface also can't use not take place to damage because of a certain interface.

The symbolic module explanation

1 carry-on dish 2 standard form USB 3 Mini USB

4 USB control chips, 5 fast flash memory bank chips

Embodiment

Fig. 1 is the process flow diagram of the utility model one preferred embodiment, and together with reference to shown in Figure 2, from figure, can be clear that, the utlity model has standard form USB 2 and 3 two kinds of interfaces of MiniUSB, and above-mentioned two kinds of interfaces are to utilize a USB control chip 4 in conjunction with single or many fast-flash memory chips 5, have non-volatile and can smear the characteristic of writing easily by fast-flash memory chip 5, can be in a large number and store or read the archives of various forms fast, as: the store video short-movie, digital photo, MP3 music and game data etc., and utilize of the access of this USB control chip 4 with the control memory body, deletion.

And 3 two kinds of interfaces of the utility model standard form USB 2 and Mini USB are to adopt the parallel way setting with combining of USB control chip 4, thereby can the situation that cause another kind of interface also can't use not take place to damage because of a certain interface.

Owing to have standard form USB 2 and Mini USB 3 double nips, meet the interface requirements of PC, notebook computer and periphery outfit thereof at present, and be compatible with present various job platform, and because USB interface also possesses the characteristic of plug and play, hot plug, it is convenient many therefore being as good as for the user.

Fig. 2 is the structural representation of the utility model one preferred embodiment, this embodiment is located at carry-on dish 1 two ends respectively with standard form USB 2 and 3 two kinds of interfaces of Mini USB, certainly, also standard form USB 2 and 3 two kinds of interfaces of Mini USB can be assemblied in the same side or side simultaneously, and this be disposed at carry-on dish the front and back end, about end, same end ... configuration modes such as .., non-patent of the present utility model are stated and are asked so no longer superfluous statement.

By the above as can be known, the carry-on dish of the utility model USB double nip has the standard form of being applicable to USB and two kinds of interfaces of Mini USB really, to meet the transmission interface data access of different size.

The above is preferred embodiment of the present utility model only, is not to be used for limiting the scope that the utility model is implemented, and the equalization of being done according to the utility model claim changes and modifies such as, is all the utility model claim and contains.
