Description
Technical field
The utility model relates to mobile storage technology and wireless communication technology, mobile storage technology, cdma wireless login technique and the Bluetooth technology of particularly utilizing USB (universal serial bus) to communicate by letter with PC.
Technical background
Use flash memory device in signal conditioning package widely, a large amount of uses is the flash memory device that utilizes USB (universal serial bus) and memory chip technology, i.e. flash disk at present.From flash disk is born certainly, because of advantages such as it need not complex drive mechanism, volume is little, easy to carry, memory space is big, easy to use are widely used.
Bluetooth (Bluetooth) is the short distance radio communication standards of being joined together to develop by mobile operator and mobile computing company, is used for designing setting up a kind of small-sized, economic, short-range Radio Link between portable computer, mobile phone and other mobile device.The frequency range of this regulation and stipulation work is public ISM band, and peak data rate can reach 1Mbps.Utilize the equipment of Bluetooth technology communication to spread all trades and professions at present, as mobile phone, notebook etc.For these bluetooth equipments are communicated by letter with the PC of no Bluetooth function easily, a kind of Bluetooth adapter of universal serial bus technology and Bluetooth technology that utilizes arises at the historic moment.Little, the no complex drive mechanism of Bluetooth adapter volume, easy to carry can be set up communication link for other bluetooth equipments and PC easily.
CDMA (Code Division Multiple Access) is the abbreviation of CDMA.CDMA can provide the transfer rate up to 2Mbit/s.The application of getting online without being tethered to a cable by mobile phone or notebook computer in being particularly suitable for moving.The cdma wireless card of surfing Internet that is used for notebook computer at present adopts pcmcia interface mostly, and this cdma wireless card of surfing Internet is of limited application, and can not be used to not have the common desktop computer of pcmcia interface.
Flash disk, Bluetooth adapter and cdma wireless card of surfing Internet all have a wide range of applications.For data on file, need to use flash disk.In order between bluetooth equipment and PC, to set up communication link, need to use Bluetooth adapter.For mobile Internet access, need to use the cdma wireless card of surfing Internet.And now need to use the occasion of above three kinds of equipment a lot of simultaneously, but they are separate equipment, this just gives to use and has brought inconvenience.
The content of invention
Technical problem to be solved in the utility model is: flash disk, Bluetooth adapter and cdma wireless card of surfing Internet are integrated formation bluetooth CDMA USB (universal serial bus) flash disk, it is except possessing high-quality remote CDMA data-transformation facility, can also realize the near radio data transmission with other bluetooth equipment, when condition restriction can't be carried out wireless transmission, it can also pass through the flash disk temporal data.Like this, no matter under any condition, can realize data sharing between various computing machine or handheld device.And have both some advantages that the three is arranged simultaneously, as: need not complex drive mechanism, volume is little, easy to carry, memory space is big, easy to use etc.
Such on the technical solution adopted in the utility model, promptly a kind of bluetooth CDMA USB (universal serial bus) flash disk comprises bluetooth USB adapter, flash disk and cdma wireless card of surfing Internet; It is characterized in that: bluetooth USB adapter, flash disk are connected with the USB interface hub by USB interface separately, the cdma wireless card of surfing Internet is connected with the USB interface hub to the USB interface conversion chip by serial ports, bluetooth USB adapter, flash disk and cdma wireless card of surfing Internet encapsulation one, the USB interface hub has the USB interface that is used for correspondence with foreign country.
The good effect that the utility model has owing to described structure is conspicuous, being about to flash disk, Bluetooth adapter and cdma wireless card of surfing Internet integrates, by USB interface hub (USBHUB) flash disk, Bluetooth adapter and cdma wireless card of surfing Internet are coupled together, transmit the data of flash disk, Bluetooth adapter and cdma wireless card of surfing Internet then by USBHUB.By being connected between the interface finishing device that is used for correspondence with foreign country of USB interface hub (USB HUB) and PC.Do not have complex drive mechanism in the structure, have that volume is little, easy to carry, memory space is big, easy to use, characteristics such as of many uses.
