The flow chart of the charging method of sub-device；Fig. 3 A is that two electronic installations are respectively connecting to fill
First USB port of electric adaptor and the schematic diagram of the second USB port；Fig. 3 B is figure
Two electronic installations of 3A are connected to the circuit diagram after charging adaptor.
The charging method of electronic installation comprises the steps of offer adaptor main body, turns
Adapter body comprises USB circuit, USB circuit have earth lead, power line, first
Data wire, the second data wire and ID line, earth lead, power line, the first data wire with
First end of the second data wire forms the first USB port, earth lead, power line,
One data wire, the second data wire form the second USB port with the second end of ID line, its
In the first data wire and the second data wire be electrically connected to each other and form short circuit, ID line
First end and the second end are electrically connected to power line (step S100)；USB transmission is provided
Line, USB transmission line comprises the 3rd USB port and the 4th USB port, and wherein the 3rd
Corresponding first USB port (step S110) of USB port；3rd USB port is connected
To the first USB port (step S120)；Second USB port is connected to the first electronics
Device (step S130)；4th USB port is connected to second electronic device (step
S140)；Judged whether the first data wire and the second data wire are short by the first electronic installation
Road (step S150)；As the first electronic installation judges the first data wire and the second data wire
For short circuit, then the first electronic installation determines whether that the first end of ID line and the second end are
No it is electrically connected to power line (step S160)；As the first electronic installation judges this ID
First end and second end of line are electrically connected to power line, then the first electronic installation is to this
Second electronic device is charged (step S170).
First, when the electric energy of second electronic device 32 exhausts and cannot be started up using,
User can will have the first electronic installation 31 of electric energy by charging adaptor 1 to the
Two electronic installations 32 are charged.
In this embodiment, the first electronic installation 31 and second electronic device 32 are with hands
Machine explains, and when practice, also can be tablet PC or other portable electricity
Sub-device；Additionally, the first electronic installation 31 (with second electronic device 32) also can be installed
There is Charging software or the program coordinating this charging adaptor 1, but be not limited to this.
Described charging adaptor 1 comprises adaptor main body 10 (step S100).Wherein,
About structure and the circuit feature of adaptor main body 10, explain in above-mentioned, in order to
For the sake of Jian Ming, it is not added with repeating in this.
Then, the USB that a USB transmission line 2 can be connected to charging adaptor 1 inserts
Groove 101a.Described USB transmission line 2 comprises the 3rd USB port 21 and the 4th USB
Port 22.Wherein, the corresponding first USB port 101 (step of the 3rd USB port 21
S110).That is, the 3rd USB port 21 has the most corresponding first USB port 101 (USB
Slot 101a) earth lead 100a, power line 100b, the first data wire 100c with
The circuit of the second data wire 100d.
Afterwards, the 3rd USB port 21 can be connected to the first USB port 101 (USB
Slot 101a) (step S120)；And by the second USB port 102 (micro USB plug
102a) it is connected to the first electronic installation 31 (step S130)；And by the 4th USB port
22 (the micro USB plugs of five pins (pin)) are connected to second electronic device 32 (step
S140)。
When the first electronic installation 31 and second electronic device 32 are by charging adaptor 1
After being electrically connected to each other with USB transmission line 2, the first electronic installation 31 then can judge
Whether the first data wire 100c and the second data wire 100d is short circuit (step S150),
Whether it is the adaptor through particular design to determine charging adaptor 1, so makes the
One electronic installation 31 determines whether to enter charge mode.
As the first electronic installation 31 judges the first data wire 100c and the second data wire
100d is short circuit, then the first electronic installation 31 determines whether adaptor main body 10
Whether the first end of ID line and the second end are electrically connected to power line 100b (step
S160).As the of the ID line of adaptor main body 10 judged by the first electronic installation 31
One end and the second end are electrically connected to power line 100b, then the first electronic installation 31 is right
Second electronic device 32 is charged (step S170).
Wherein, in this embodiment, due to the first of the ID line of adaptor main body 10
End and the second end have been electrically connected to power line 100b, therefore the first electronic installation 31 the most
Judge it itself is directly second electronic device 32 (by electricity side) to be entered as supplier of electricity
Row charging.Additionally, above-mentioned Charging software or program can be coordinated, the first electronic installation 31
Now enter standby mode, and the relevant information of charging can be shown (such as: set in screen
Determine the information such as electric current or output electric current).
It follows that utilize charging adaptor 1 to be available for first electronic installation with electric energy
31 pairs of second electronic devices 32 without electric energy are charged.And due to the first electronics dress
Put 31 with second electronic device 32 be all carrying convenience mobile phone (or for flat board calculating
Machine), in the life therefore generalized for current mobile phone, utilize this charging adaptor 1 to make
Directly being charged operation between mobile phone and mobile phone or mobile phone and tablet PC is the most just
Profit.
Refer to the circuit that Fig. 4, Fig. 4 are another embodiment of the present invention charging adaptor
Schematic diagram.
As shown in Figure 4, this embodiment is only that with the difference of Fig. 3 B: USB circuit is also
Comprise switching switch (not illustrating).Switching switch is in order to by first end and second of ID line
End electrically cuts off power line 100b, so that the first end of ID line and the second end electrically connect
It is connected to earth lead 100a.
After judging that the first data wire 100c and the second data wire 100d is short circuit, the
Second electronic device 32 (by electricity side) then will not be charged by one electronic installation 31.
Wherein, described switch may be provided at the hull outside of adaptor main body 10, for use
Person makees to switch and decide whether to utilize the first electronic installation 31 to second electronic device 32
It is charged.
In sum, only notebook is invented as presenting the technology hands that solution problem is used
The better embodiment of section or embodiment, be not used for limiting patent of the present invention real
The scope executed.The most all it is consistent with present patent application scope context, or according to the present invention
Equalization change and the modification that the scope of the claims is done, is all the scope of the claims of the present invention and is contained.
