A kind of Multifunctional portable power source

Technical field

The utility model relates to the portable power source for connecting portable equipment and computer or power supply adaptor.

Background technology

Along with science and technology and social progress, portable laptop computers, panel computer and intelligent mobile phone are popularized.All mancarried electronic aids all use rechargeable battery, carry out transfer of data and charging with data wire.Because volume limit, the portable power source as the standby electricity of mobile phone starts to popularize.

Existing portable power source only has charging/discharging function, cannot have the quick charge and data line transfer function of supporting mobile phone charge protocol simultaneously.

After mobile phone and computer connect, also to solve normally carrying out with/without data function switching; Because the software systems of some portable equipment can not be triggered in time.

Summary of the invention

For the problems referred to above, the utility model aims to provide a kind of Multifunctional portable power source.There is the quick charge and data line transfer function of supporting mobile phone charge protocol simultaneously.

For realizing this technical purpose, scheme of the present utility model is: a kind of Multifunctional portable power source, comprises the first interface for docking portable equipment and management of charging and discharging module, and the first interface of docking portable equipment is connected with management of charging and discharging module for power supply; Also comprise rechargeable battery, rechargeable battery is connected with management of charging and discharging module for power supply; Also comprise the second interface of docking computer or power supply adaptor, the second interface is connected with management of charging and discharging module for power supply; Also comprise usb data gating switch, the up going port of usb data gating switch is connected with first interface data communication; Also comprise charge protocol recognition unit, the two-way down going port of usb data gating switch is connected with the second interface and the data communication of charge protocol recognition unit difference.

The management of charging and discharging module of responsible rechargeable battery discharge and recharge wherein comprises Charge Management unit and exports DC/DC unit; There is the single-chip of a lot of integrated functionality in existing market, the ETA6082 etc. of the safe electronics of such as treasure; It is mature technology.

Charge protocol recognition unit wherein supports the identification IC of various protocols or the setting resistance of single charge protocol.The charger of Apple's product uses different resistances to set.Market there is many moneys charge protocol identification IC, such as MA5887, MA5889 of strange rock electronics; GL888, GL889M etc. of Taiwan Skyworth.

Usb data gating switch is wherein toggle switch or USB analogue data switch.USB analogue data switch is very ripe product, and there are Related product in fairchild company of the U.S., Shanghai Belling etc.; The BL1532 of such as Shanghai Belling, as long as the state of the Sel pin of control chip, can select data channel

As preferably, described a kind of Multifunctional portable power source also comprises a switch, and the two ends of switch are connected with first interface and management of charging and discharging module for power supply respectively.Switch is set up on the power line between the first interface and management of charging and discharging module of docking portable equipment.

The beneficial effect of the technical program is: realize a kind of Multifunctional portable power source, has the quick charge and data line transfer function of supporting mobile phone charge protocol simultaneously.After mobile phone and computer connect, the normal switching with/without data function can also be carried out.
