Description
Technical field
The utility model relates to the portable power source technology, specifically is a kind ofly in the USB system, both can make main equipment, also can make the multi-functional portable power source of slave unit.
Background technology
Along with popularizing of smart mobile phone, panel computer, the function of portable digital equipment from strength to strength; Power consumption also heightens simultaneously.In order to replenish electric power for portable digital equipment, portable power source increases thereupon, becomes a lot of users' necessary article.In the existing portable power source, some has a plurality of USB interfaces; But all only as the interface of externally supplying power.Data-signal pin or short circuit in the interface; Perhaps connecting resistance.
The interface of portable digital equipment is limited, and owing to the volume reason, mostly adopts ultra-thin low profile interface; This causes portable digital equipment very inconvenient with being connected of peripheral hardware.Simultaneously, some peripheral hardware needs bigger electric current support, and the interface of portable equipment does not possess the ability that big electric current is provided usually; Like this, these outer being located at do not have can't normally use under the additional power supply electric power thus supplied.
In digital equipments such as mobile phone, panel computer, adopt USB OTG interface to charge and data communication more; According to the high-low level state of ID pin in the USB OTG interface, digital equipment is respectively as main equipment or slave unit: when internally charging, as slave unit; Reading equipment such as external USB flash disk when digital, as main equipment.
Summary of the invention
To the problems referred to above, the utility model aims to provide a kind of USB interface that utilizes second interface of portable power source as expansion; Can be its novel digital equipment portable power source that provides electric power to support simultaneously.
For realizing this technical purpose, the scheme of the utility model is: a kind of multi-functional portable power source comprises rechargeable battery module; Also comprise first interface that docks with digital equipment, said first interface is connected with the rechargeable battery module power supply; Also comprise ID pin level control unit; This control unit and the corresponding connection of ID pin in first interface; ID pin in first interface docks with ID pin in the digital equipment USB interface, is used for controlling the high-low level state of ID pin in the digital equipment USB interface; Also comprise second interface, this interface is a USB interface, and this interface is communicated by letter with first interface data and is connected; Also comprise the DC input interface, the DC input interface is connected with the rechargeable battery module power supply.。
As improvement, the USB interface of said second interface is connected with the rechargeable battery module power supply.
As further improvement, between the USB interface of said first interface that docks with digital equipment and second interface, device has the usb signal switch, and data communication is connected this usb signal switch with second interface difference with first interface.
Wherein rechargeable battery module comprises Charge Management unit, rechargeable battery and DCDC unit; Under the DC input condition, the Charge Management unit is responsible for managing to the rechargeable battery charging and to charged state; DCDC is responsible for the unit voltage transitions of rechargeable battery is the required voltage of output.Each unit is existing mature technology.
This programme is integrated in expanding USB interface on the portable power source, both can be used as second interface of external power supply, and the ECP Extended Capabilities Port that can be used as portable digital equipment again inserts peripheral hardwares such as USB flash disk, portable hard drive; Rechargeable battery module can provide sufficient electric power for peripheral hardware, guarantees their normal use; High-low level control through to ID pin in first interface realizes the switching of digital equipment master slave mode.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
As shown in Figure 1, a kind of multi-functional portable power source of the utility model comprises rechargeable battery module 1; Also comprise first interface 2 that docks with digital equipment, said first interface 2 is connected with rechargeable battery module 1 power supply; Also comprise ID pin level control unit 3; The corresponding connection of ID pin in this control unit 3 and first interface 2; ID pin in first interface 2 docks with ID pin in the digital equipment USB interface, is used for controlling the high-low level state of ID pin in the digital equipment USB interface; Also comprise second interface 4, this interface 4 is a USB interface, and this interface 4 is connected with 2 data communication of first interface, is connected with rechargeable battery module 1 power supply; Also comprise DC input interface 5, DC input interface 5 is connected with rechargeable battery module 1 power supply.
As shown in Figure 2, in specific embodiment two, between first interface 2 that docks with digital equipment and the USB interface 4 of second interface, device has usb signal switch 6, and 4 difference data communication are connected this usb signal switch 6 with second interface with first interface 2.When second interface 4 used as the expanding USB interface of first interface 2, usb signal switch 6 was connected.
As shown in Figure 3, sketch map one is used in the utility model practical implementation; Mobile phone USB OTG interface is connected with first interface 2 through data wire, if the ID pin at this moment in first interface is a high level, then portable power source is to cell-phone charging; If the ID pin in first interface is a low level, then mobile phone can be read and write the u dish data of inserting from second interface 3; Rechargeable battery module 1 can be the u dish power supply of inserting simultaneously.Realized the switching of the master and slave different conditions of digital equipment when reading external data like this with charging.
As shown in Figure 4, sketch map two is used in the utility model practical implementation; First interface 2 adopts female mouthful of USB3.0; USB2.0 partly docks in USB2.0 part among female mouthful of the USB3.0 and the digital equipment USB interface, in other pin of USB3.0, chooses a pin as the ID pin.Adopt mass-produced USB3.0 interface like this, both with the USB2.0 interface compatibility, the ID pin that also provides the control appliance state to need.
The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection range of the utility model technical scheme.
