In sum, the platform that is used for providing the charging service to equipment to be charged of the present utility model can effectively identify the non-standard charger of access by identification circuit, thereby realizes the charging operations to it.
Other aspects of the present utility model will be apparent to those skilled in the art owing to the disclosure of this paper.
Below in conjunction with accompanying drawing the utility model/utility model is elaborated.
Embodiment
See also Fig. 1, of the present utility model being used for provides the platform of charging service to comprise to equipment to be charged: connecting interface, identification circuit, charge power supply, start-up circuit.
Described connecting interface is corresponding with the charging inlet of equipment to be charged, and it comprises first data wire 11, second data wire 12, first power line 13, reaches second source line 14.Wherein, equipment to be charged can be USB charger, standard charging device or non-standard charger etc.; Described first power line 13 is generally the positive supply line, and second source line 14 is generally earth connection.Because equipment to be charged can be various dissimilar, and the charging inlet of dissimilar equipment to be charged, the connecting line that is comprised also might not be identical separately, for example, some may only have only first power line and second source etc., so being connected of first data wire 11 among Fig. 1 between employing dotted line sign connecting interface and the charging inlet and second data wire 12, being connected some situations and may not existing to show those.In addition, those skilled in the art should understand that, first data wire 11, second data wire 12, first power line 13, and the arrangement of second source line 14 be not to exceed with shown in Figure 1 yet, for example, also can be first power line 13, and second source line 14 be on first data wire 11 and second data wire 12 or the like.
Described identification circuit and described first data wire 11, second data wire 12, first power line 13, and second source line 14 be connected, be used for type, whether need the signal that charges with output according to the equipment to be charged that first power line 13 is used for, the signal identification of first data wire 11 or second data wire 12 is inserted.For example, discern the signal that described first power line 13 inserted when described identification circuit and be lower than 9v, whether the signal that then described identification circuit is discerned first data wire 11 or second data wire 12 again is interrupt signal, rising edge signal etc. for example, if, it is the standard charging device that then described identification circuit identifies equipment to be charged, thereby output needs the signal of charging.
Described start-up circuit is connected with described identification circuit, simultaneously, it is connected between charge power supply and described first power line 13 and the second source line 14, be used for signal according to the needs charging of described identification circuit output, described charge power supply is loaded between described first power line 13 and the second source line 14, so that charge power supply is charged to battery of correspondence etc. by equipment to be charged.
Above-mentioned connecting interface, identification circuit, and start-up circuit can be incorporated on the same chip, to form power management chip etc.Wherein, identification circuit can adopt microprocessor, digital signal processor etc., and start-up circuit can adopt controlled switch etc.
See also Fig. 2 again, it is the above-mentioned workflow schematic diagram that is used for providing to equipment to be charged the platform of charging service.
At first, after the charging inlet of equipment to be charged is connected to described connecting interface, whether the identification earlier of described identification circuit surpasses preset value by the signal that first power line 13 inserts, for example, 9v is not if then described identification circuit is just exported the signal that needs charging, thereby start-up circuit is not worked, and the charge power supply and first electric power connection line 13 or second source connecting line 14 are in off-state; And if identification circuit identifies the signal of first power line, 13 accesses less than 9v, then whether its signal of further discerning first data wire 11 or second data wire 12 is interrupt signal, for example, whether be the rising edge signal, if, then to identify equipment to be charged be the standard charging device to identification circuit, thereby output needs the signal of charging; And if the signal that identification circuit is discerned first data wire 11 or second data wire 12 is not interrupt signal, then its by further with the communicating by letter of first data wire 11 or second data wire 12, for example, transmission (for example meets the predetermined protocol form, the usb of USB_OTG enumerates agreement etc.) a certain signal, if the feedback signal that identification circuit is received also meets predetermined protocol form (usb that is USB_OTG enumerates agreement etc.), then to identify equipment to be charged be the USB charger to identification circuit, thereby output needs the signal of charging; If the feedback signal that identification circuit is received does not meet predetermined protocol form (usb that is USB_OTG enumerates agreement etc.), then to identify equipment to be charged be non-standard charger to identification circuit, thereby also output needs the signal of charging.Thus, start-up circuit is carried in charge power supply between described first power line 13 and the second source line 14 after receiving the signal that needs charging.
In sum, of the present utility model being used for provides the identification of the platform of charging service by identification circuit to equipment to be charged, can be to dissimilar, especially non-standard charger charges, so, have very strong practicality for the user of the non-standard charger of numerous uses provides a great convenience.
It will be understood by those skilled in the art that after having read above-mentioned instruction content of the present utility model, can make various changes or modifications that these equivalent form of values fall within the application's appended claims institute restricted portion equally to the utility model.
