Description
Technical field
The utility model relates to technical field of electronic products, especially a kind of data line with USB flash disk function.
Background technique
It is well known that data line (data cable), acts on to connect mobile device and computer, to reach data
Transmitting is communication objective.Popular point is said, exactly connects computer and mobile device is used to transmit the files such as video, the tinkle of bells, picture
Access tool.Now, with the development that electronics industry is maked rapid progress, data line has become indispensable in our lives
Part.
But existing data line only has data-transformation facility and charge function, if desired having a single function stores one
A little files read file, require in addition to carry a USB flash disk, when so that carrying outdoors, will make troubles to user, individually
USB flash disk is carried also to be easily lost.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide a kind of with USB flash disk function
Data line.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of data line with USB flash disk function, including main body and several data terminals being connect by transmission line with main body
Mouthful and several plugs, be provided with button in the main body and be built-in with control panel, be integrated on the control panel MCU chip and
USB flash disk switching circuit, the button are connected to MCU chip, the USB flash disk switching circuit include memory module, the first MOS switch group,
Second MOS switch group, the MCU chip are connect with the first MOS switch group and the second MOS switch group respectively, the memory module
It is connected to by the first MOS switch group with transmission line, the second MOS switch group is connected to transmission line.
Preferably, the data port is USB female seat, the plug be micro USB plug or type-c plug or
Lightning plug.
Preferably, the memory module is flash storage.
As the above scheme is adopted, the utility model is by data port and plug to the logical function for realizing traditional data line
The transmission of energy, i.e. data and power source charges；Meanwhile being connected to by data port or plug with memory module, Lai Shixian USB flash disk stores function
The storage of energy, i.e. file and read functions；Also, the switching of the two functions is controlled, by button to facilitate user to carry out function
Selection removes tyre USB flash disk to meet the function of integrating USB flash disk storage under data line conventional func, and structure is simple, operates just
Victory has very strong practicability.

Fig. 2 is the operation principle schematic diagram of the utility model embodiment.
Fig. 3 is the first protocol procedures schematic diagram of the utility model embodiment.
Fig. 4 is the second scheme flow diagram of the utility model embodiment.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As shown in Figures 1 to 4, a kind of data line with USB flash disk function provided in this embodiment, including main body 1 and pass through
Several data port 3 and several plugs 4 that transmission line 2 is connect with main body 1 are provided with button 5 in main body 1 and are built-in with control
Making sheet (not shown) is integrated with MCU chip 6 and USB flash disk switching circuit on control panel, and button 5 is connected to MCU chip 6, USB flash disk
Switching circuit includes memory module 7, the first MOS switch group 8, the second MOS switch group 9, and the first MOS switch group 8, the 2nd MOS are opened
Pass group 9 is made of at least four metal-oxide-semiconductors, and MCU chip 6 is connect with the first MOS switch group 8 and the second MOS switch group 9 respectively,
Memory module 7 is connected to by the first MOS switch group 8 with transmission line 2, and the second MOS switch group 9 is connected to transmission line.
The data port 3 and plug 4 of the present embodiment can connect computer, adapter or mobile phone,
1, when data port 3 and plug 4 connect computer and mobile phone respectively, readable in computer data in mobile phone at this time, while can give
Mobile phone charging；
2, when data port 3 connects adapter, plug 4 takes over machine, and adapter can charge the phone at this time；
3, when data port 3 or plug 4 only have a termination computer, computer can read the information in memory module 7 at this time,
Realize USB flash disk reading data function.
4, machine is taken over when data port 3 and plug 4 only have one end, mobile phone can read the number in memory module 7 at this time
According to.
Specific practical realize can be divided into two schemes:
As Fig. 3 the first are as follows: after data port 3 is first inserted into, MCU chip 6 is directly powered at this time, can be with runs software journey
Sequence, program record is that data port 3 powers on, and then controls the second MOS switch group 9 by MCU chip 6 and both ends are connected, into number
According to ray mode, if data line has worked normally at this time without pressing lower button 5, lower button 5 is such as pressed, inside MCU chip 6
Data line is switched to USB flash disk mode, i.e. the first MOS switch group 8 conducting by program.
Such as second of Fig. 4 are as follows: need first plug 4 to connect mobile phone, then judge whether data port 3 connects computer, button 5 is
No to press, when data port 3 accesses computer or simultaneously button 5 is pressed, then MCU chip 6 powers on (is extracted in mobile phone by plug 4
Electric energy), into the sequence of storage electrifying timing sequence, and continue whether detection button 5 is pressed, transmission line 3 be connected if pressing
With memory module 7, into USB flash disk mode, if not press lower button 5, be normal data ray mode.
Further, data port 3 can be used USB female seat, plug 4 can be used micro USB plug or type-c plug or
Lightning plug.Further, flash storage can be used in memory module 7.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
