Description
Technical field
The utility model relates to a kind of single USB interface and discharges and recharges portable power source, is mainly used in the charging of the electronic equipments such as music player, mobile phone.
Background technology
At present, electronics technology is fast-developing, and the electronic product such as music player, mobile phone is various in style on the market, and these electronic products are extremely general in consumer's hand.Simultaneously, because these products, particularly smart mobile phone, power consumption is very big, and the capacity of monolithic battery of mobile phone is very limited.A lot of consumers are several batteries for subsequent use, to realize continuous use.Thus, various stand-by power supplies have appearred on the market.
In recent years, occur a kind of portable power source on the market to realize charging, reached continuous use.Some portable power sources have used USB interface.Because the difference of voltage request, in order to realize the function to the charging and discharging of portable power source, a kind of method is to use two USB interface, this method uses inconvenience, and easily because user's wrong interface, and portable power source is burnt out, and simultaneously more interface represents to take more space, and this volume requirement for portable power source is a disadvantageous factor.Another kind method is to use single USB interface, but discharge and recharge the function that control switch is controlled this single USB interface by one, although solved the drawback that reduces space hold, but because the function of single USB interface need to be controlled by discharging and recharging control switch, use still inconvenience, and can't avoid burning out the potential drawback of portable power source.These problem values must solve improvement.
The utility model content
The purpose of this utility model provides a kind of single USB interface and discharges and recharges portable power source, when avoiding taking up room, adopt single USB interface, realize the direct charging/discharging function of individual interface, solved and used inconvenience, burn out easily the drawback of portable power source, make the simple to operation of portable power source.
The realization the technical solution of the utility model is as follows: a kind of single USB interface discharges and recharges portable power source, comprise main control MCU, it is characterized in that, described main control MCU connecting electronic equipment inserts the sampling identification circuit, switch is carried out in discharge to electronic equipment, identification circuit internally charges, internally switch is carried out in charging, internal charge management circuit, and LED light, described electronic equipment inserts the sampling identification circuit and connects the USB interface negative pole, describedly switch is carried out in electronic equipment discharge be connected to booster circuit, and be connected to USB interface by booster circuit, described internal charging identification circuit connects USB interface, and carry out switch with the internal charging that is connected USB interface, indirectly link to each other, described internal charging is carried out the switch connection and is linked to each other with described internal charge management circuit, and described internal charge management circuit is connected to internal cell.
Realize that the technical solution of the utility model comprises that also described main control MCU connects at least one LED display lamp.
Description of drawings
Fig. 1, circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific implementation method the utility model is described further:
A kind of single USB interface discharges and recharges portable power source, comprise main control MCU, it is characterized in that, described main control MCU, respectively connecting electronic equipment insert the sampling identification circuit, to electronic equipment discharge carry out switch, internally charge identification circuit, internally switch, internal charge management circuit are carried out in charging, connect simultaneously LED light.Described electronic equipment inserts the sampling identification circuit and connects USB interface, describedly switch is carried out in electronic equipment discharge be connected to booster circuit, and be connected to USB interface by booster circuit, described internal charging identification circuit connects USB interface, and carry out switch with the internal charging that is connected USB interface, indirectly link to each other, described internal charging is carried out the switch connection and is linked to each other with described internal charge management circuit, and described internal charge management circuit is connected to internal cell.
When carrying out the discharge order, electronic equipment inserts USB interface, and described electronic equipment inserts the sampling identification circuit, recognize discharge information, after main control MCU is processed, carry out switch by the discharge to electronic equipment that connects, carry out discharge, and by booster circuit, be connected to USB interface.
When carrying out charge command, external power source inserts USB interface, described internal charging identification circuit, recognize charge information after, after main control MCU is processed, carry out switch and internal charge management circuit by internal charging, carry out charge command, internal cell is charged.
Realize the utility model, comprise that further described main control MCU connects at least one LED display lamp, jointly feed back the charging and discharging state that described single USB discharges and recharges portable power source.
The utility model adopts single USB interface, realizes the direct charging/discharging function of individual interface, and is easy to use, avoids burning out portable power source, makes the simple to operate of portable power source, safe and effective.
