Electronic product annex volume is more and more little at present, but function singleness, in order to reach various purposes, must carry different electronic product annexes, such as charger, data line, USB flash disk, MP3 etc., how can effectively various products be merged, to guarantee that simultaneously it is easy to carry about with one also is the problem that consider emphatically.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of portable charged data logical, solves the charging problem of electronic product under the state of emergency; Simultaneously fused data transfer function and storage, amusement function, simple in structure, portably use conveniently.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:
A kind of portable charged data are logical, comprise charging circuit, discharge line and storage battery; Described charging circuit is provided with charging control switch or charged state checkout gear, and described discharge line is provided with discharge control switch or discharge condition detection apparatus; Described charging circuit comprises charging USB interface and charging device, and the input of described charging device connects the charging USB interface, and the output of charging device connects the input of storage battery; Described discharge line comprises discharge USB interface and electric discharge device, and the input of described electric discharge device connects the output of storage battery, and the output of electric discharge device connects the discharge USB interface; Be connected with data line between described charging USB interface and the discharge USB interface; Be connected with data storage device on the described data line.
Described charging USB interface and discharge USB interface can adopt existing on the market various USB interface, such as A type USB interface, Mini type USB interface, Micro type USB interface etc.; Simultaneously, charging USB interface or discharge USB interface can adopt that more than one veriform USB interface is in parallel to be used, and communicate by letter or charge etc. so that is connected with various electronic product.
Described charging USB interface and discharge are connected with data line between the USB interface, and two ports that the USB interface of charging this moment and discharge USB interface just can be used as data transmission device use, with data-transformation facility be fused to portable charged data logical on.
The described data storage device that is connected on the data line can be various card reader, USB flash disk, Micro SD adapter or Mini SD adapter etc., can also directly be connected on the memory member of the various amusement type electronic products of carrying, such as MP3, MP4, MP5, Radio, phonographic recorder etc.
Charging device and electric discharge device can adopt chip structure, can reduce the logical volume of whole portable charged data like this, storage battery can be selected the corresponding battery capacity as required, as using under the general state of emergency, the capacity of battery is unnecessary very big, used for 20 to three ten minutes such as the conversation of power supply words, at this moment, the respective volume of battery is also smaller.Compress the logical volume of portable charged data, can make it be designed to the suspension member form, be convenient for carrying.
During use, only need to connect the external charge power supply, just can charge, also can use indicator light indication storage battery whether to charge and finish to storage battery by the charging USB interface; When mobile phone or other electronic products need to use emergency power supply under the state of emergency, only need the discharge USB interface that portable charged data are logical be connected with the charging inlet of electronic product, promptly can charge to electronic product.
Can be used for selecting logical being in for storage battery of portable charged data to carry out charged state by charging control switch or charged state checkout gear; Can be used for selecting logical being in for electronic product of portable charged data to carry out charged state by discharge control switch or discharge condition detection apparatus.
Described charging device is the DC/DC buck converter, and storage battery is charged; Described electric discharge device is the DC/DC booster converter, and electronic product is charged.Parameters such as the operating voltage of DC/DC buck converter and DC/DC booster converter and operating current are selected to set according to the specifications parameter of storage battery, and with the storage battery specifications vary difference.
DC/DC buck converter DC/DC booster converter can constitute by devices such as chip/resolution element and peripheral capacitor and inductors, mainly realizes input voltage and output voltage conversion.Such as external input voltage is 5V, becomes voltages such as 4.2V or 3.7V through the DC/DC buck converter, and storage battery is charged; The voltage of storage battery to obtaining, promptly voltage such as 4.2V or 3.7V becomes 5V or 5.5V etc. through the DC/DC booster converter, and electronic product is charged.The input and output electric current of DC/DC buck converter DC/DC booster converter also can be regulated and be set.
Described storage battery is preferably the high rate lithium battery, and this mainly is because the high rate lithium battery has characteristics such as volume is little, discharging current is big.
The input of charging device also is connected with 2.5/3.5mm charge power supply joint; The output of electric discharge device also is connected with 2.5/3.5mm discharge power supply joint.Selecting charging USB interface and discharge USB interface for use is in order to merge existing general standard, but also has electronic product form that adopt or charge power supply joint and discharge power supply joint greatly at present, charge power supply joint and discharge power supply joint are also merged at portable charged data Tongli, make that its electronic product that can be suitable for is more extensive.
