Abstract
The utility model relates to a Blue Tooth adapter with a flash memory disk, which comprises a Blue Tooth USB adapter and a flash memory disk, characterized in that the Blue Tooth USB adapter and the flash memory disk are connected with each other by an USB interface concentrator through respective USB interface, and packaging as an unit, the USB interface concentrator is provided with an USB interface exposed to a container. The utility model completes storing function through the flash memory disk, completes function of communication with a Blue Tooth device through the Blue Tooth adapter, and the USB interface concentrator (USB HUB) completes transferring data between the flash memory disk and PC, and between the Blue Tooth adapter and PC. Without complicated actuating mechanism in structure, the utility model is characterized by small volume, carried conveniently, large memory capacity, convenient utilization and wide usage and the like.
Description
Technical field
The utility model relates to mobile storage technology and wireless communication technology, particularly utilizes the Bluetooth adapter of the band flash disk that mobile storage technology that USB and PC communicate by letter and Bluetooth technology combine.
Technical background
Use flash memory device in information processor widely, a large amount of uses is the flash memory device that utilizes USB 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 1 Mbps.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.
Flash disk and Bluetooth adapter all have use widely.For data on file, need to use flash disk.And, need to use Bluetooth adapter for for bluetooth equipment and PC set up communication link.And now need to use the occasion of flash disk and bluetooth USB adapter a lot of simultaneously, but they are two separate equipment, this just gives to use and has brought inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of have simultaneously memory function and function of Bluetooth communication are provided, and have both some advantages that the two is arranged simultaneously, promptly need not the Bluetooth adapter of complex drive mechanism, volume is little, easy to carry, memory space is big, easy to use band flash disk.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is such, and promptly a kind of Bluetooth adapter with flash disk comprises bluetooth USB adapter and flash disk; It is characterized in that: bluetooth USB adapter and flash disk are connected by the USB interface hub by USB interface separately, and the encapsulation one, and the USB interface hub has the USB interface that exposes to housing.
The good effect that the utility model has owing to described structure is conspicuous, promptly finish the function of storage by flash disk, finish function with bluetooth devices by bluetooth USB adapter, the interface that exposes by USB interface hub (USB HUB) is finished between flash disk and PC, and forwarding of data between bluetooth USB adapter 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.
Description of drawings
Structure of the present utility model can further specify by accompanying drawing.
Fig. 1 is the utility model structural principle block diagram;
