Abstract
The Bluetooth adapter with flash memory consists of a blue tooth USB adapter and a flash memory, which is characterized in, the Bluetooth USB adapter and the flash memory are connected through USB ports by USB port wire concentrators, respectively, and sealed into a body. The USB port wire concentrators have the USB ports outside the shell. The function of storage is accomplished by the flash memory of the invention. Data is transmitted between the flash memory and PC, between the Bluthtooth adapter and PC by the USB port wire concentrators. The device has no complex drivers, with small volume, large memory, widely usage, etc.
Description
Technical field
The present invention relates to mobile storage technology and wireless communication technology, particularly utilize 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 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.
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 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 by this invention 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 used in the present invention is such, and promptly a kind of Bluetooth adapter with flash disk comprises bluetooth USB adapter and flash disk; It is characterized in that: suitable USB orchestration of bluetooth 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 present invention 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 invention can further specify by accompanying drawing.
Fig. 1 is a structural principle block diagram of the present invention;
Fig. 2 is the schematic appearance of structure embodiment of the present invention;
Fig. 3 is the electrical block diagram of bluetooth USB adapter.
In the accompanying drawing 1,2: 1-USB exposes interface, 2-housing, 3-suspender, 4-bluetooth USB adapter, 5-USB interface hub, 6-flash disk.
In the accompanying drawing 3: J1 is the USB joint of standard, and voltage conversion circuit chip U1 model is 7301, by it 5V power source conversion is become 3.3V, and the model of bluetooth module (U2) is the ROK10100 of Ericsson.R1, R2, R3 are resistance in an embodiment, and A1 is a microstrip antenna.
Embodiment
As shown in Figure 1, the present invention includes bluetooth USB adapter 4, flash disk 6, wherein the USB interface of bluetooth USB adapter 4 is connected with USB interface hub 5, and the USB interface that flash disk has is connected with USB interface hub 5.Flash disk in the device is mainly finished the function of storage, and bluetooth USB adapter is finished the function with bluetooth devices, USB interface hub 5 and expose usb 1 and finish between flash disk and PC, and forwarding of data between bluetooth USB adapter and PC.
As shown in Figure 2, have USB on the housing 2 of the present invention and expose interface 1 and suspender 3, encapsulation bluetooth USB adapters 4, flash disk 6 and USB interface hub 5 in the housing 2 and constitute portable (being called as the D dish).USB exposes interface 1 and is used to connect PC, and suspender 3 can adopt link and carry after being convenient to add lanyard.
Referring to accompanying drawing 3, bluetooth USB adapter comprises USB interface, microstrip antenna, bluetooth module and voltage conversion circuit among the figure; Wherein, the radio-frequency (RF) signal input end of bluetooth module is connected with microstrip antenna, the 5V power end of USB interface is connected with the input of voltage conversion circuit, the 3.3V voltage output end of voltage conversion circuit is connected with the power input of bluetooth module, and the data terminal of USB interface connects the data terminal of bluetooth module by the Signal Matching circuit.
In the accompanying drawing 3,1 pin of USB joint J1 is Vcc, and for the 5V power supply inputs to the voltage input end Vin of voltage conversion circuit chip U1, the voltage conversion circuit chip is powered to bluetooth module from voltage output end Vout output 3.3V.The D+ of USB joint J1 is the data anode, D-is the data negative terminal, give D+, the D-end of bluetooth module U2 behind the Signal Matching circuit of their signal via resistance R 1, R2, R3 formation, in bluetooth module U2, change into Bluetooth signal and give microstrip antenna A1, send to the space by it.Microstrip antenna A1 is a L shaped antenna that is arranged on the pcb board.
