Description
Technical field
The present invention relates to portable back-up source field, refer more particularly to portable back-up source and discern the output voltage electric current automatically.
Background technology
At present; Because products such as present various mobile phones, notebook computer, number, panel computer all need various power supplys to its power supply or charging; But because of the different required voltage electric currents differences of various device function, and make the time, need to select the voltage and current of correspondence to various device power supply or charging; Otherwise can make equipment various undesirable conditions occur, serious also can cause the equipment permanent damage.Existing each producer uses different interface modes on Different products to this problem; But because of products such as present various mobile phones, notebook computer, number, panel computer all can't use going out for a long time; Everybody brings into use portable back-up source to supply power or charge for various portable equipments; Because various device required voltage electric current is different, all uses artificial mode to remove to select required electric current and voltage on the traditional handicraft, the result causes much and takes place because of misoperation causes the device damage situation.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of simple in structure, easy to operate, discern portable back-up source output voltage electric current automatically, practical novel portable back-up source is discerned the output voltage electric current automatically.
The present invention realizes through following mode:
Portable back-up source is discerned the output voltage electric current automatically, comprises charging output line 1, public 2 of power supply out splice going splice, female 3 of power supply out splice going splice, back-up source 4, and wherein: charging output line 1 is connected with public 2 of power supply out splice going splice; The public seat 2 of described power supply out splice going splice is connected with the female seat 3 of power supply out splice going splice, and the female seat 3 of described power supply out splice going splice is connected on the back-up source 4; It is characterized in that: the public seat 2 of described power supply out splice going splice is provided with resistance recognition device RT1; Described back-up source 4 is provided with more than one out-put supply control IC, and described out-put supply control IC is connected with the female seat 3 of power supply out splice going splice.
On resistance recognition device RT1 on the public seat 2 of described different electrical power out splice going splice and the back-up source 4 accordingly the out-put supply control IC be connected.
The invention has the advantages that: the public seat of power output interface simple in structure, as to utilize various correspondences is gone up to increase resistance recognition device or the public seat of difform output interface and increase the resistance RM and is given the out-put supply control IC in the stand-by power supply signal feedback; Because of identification resistance device value difference of each public seat causes the input voltage after the dividing potential drop different; Reach the out-put supply control IC and send the voltage and current that the corresponding electric power output voltage IC of instruction controls the output correspondence, other then turn-off and do not export.

Embodiment
Combine accompanying drawing at present, the specific embodiment of the invention be detailed:
Like Fig. 1, shown in Figure 2, portable back-up source is discerned the output voltage electric current automatically, comprises charging output line 1, public 2 of power supply out splice going splice, female 3 of power supply out splice going splice, back-up source 4, and wherein: charging output line 1 is connected with public 2 of power supply out splice going splice; The public seat 2 of described power supply out splice going splice is connected with the female seat 3 of power supply out splice going splice, and the female seat 3 of described power supply out splice going splice is connected on the back-up source 4; It is characterized in that: the public seat 2 of described power supply out splice going splice is provided with resistance recognition device RT1; Described back-up source 4 is provided with more than one out-put supply control IC, and described out-put supply control IC is connected with the female seat 3 of power supply out splice going splice.
On resistance recognition device RT1 on the public seat 2 of described different electrical power out splice going splice and the back-up source 4 accordingly the out-put supply control IC be connected.
The public seat of described power supply out splice going splice can be the power source charges data wire of different mobile phones, notebook computer, number, panel computer.
The present invention utilizes to increase resistance recognition device RT1 or the public seat 2 of difform output interface on the public seat 2 of the power output interface of various correspondences and increase the resistance RM and gives the different out-put supply control IC in the stand-by power supply signal feedback; Cause the input voltage difference after the dividing potential drop because of identification resistance device RT1 value of each public seat is different; The power supply control IC that reaches output is sent the voltage and current that the corresponding electric power output voltage IC of instruction controls the output correspondence, and other then turn-off and do not export.
