Abstract
A kind of charging device, can to portable phone in the identical time, charge and no matter the phone internal electric source in " opening " or "off" state.Inserted charging device when predicting phone, determined that the phone internal electric source is in " opening " or " pass " state, the charging current that enters phone depends on " ON/OFF " state of telephone power and changes.
Description
The present invention relates to the charging device of portable phone, particularly relate to a kind of charging device, can all in the identical time, charge at the state that opens or closes regardless of power supply in the phone to portable phone.
Power by battery or similar power supply at the current portable phone that is widely used.When power supply exhausted, phone was just received charging device and is charged by it.Charging device has a phone test section to be used to detect phone whether to have received device usually; A charging current source is used for the power supply supplying charging current to phone in addition; And have a switch to be used for that charging current source is received telephone power to get on.When phone was received charging device, this device detected this connection and makes switch motion so that charging current is presented to telephone power from charging current source with the phone test section.The conventional common way of charging device is no matter how the open/close state of telephone power all keeps charging current constant.Yet this causes following problem: the supposition telephone power needs T in "off" state
1Time is full of, and needs T in "open" state
2Time.So, when telephone power is less than the charging current of being presented by charging current source at the electric current that in fact "open" state charges into power supply,, a part of charging current consumed because being used as the operating current of phone.Time T as a result
2Than time T
1Long, promptly will be much larger than charging interval in "off" state in the "open" state charging interval.This makes that charging is unpractical to telephone power when " opening " state.
Therefore, the purpose of this invention is to provide a kind of charging device, it is no matter power supply can both charge to portable phone with the identical time at " opening " or " pass " state in the phone.
The charging device that the portable phone internal electric source is charged of the present invention comprises a support, and portable phone can be received on it; A charging current source is used for the power feed electric current to portable phone; A phone test section is used for determining whether portable phone is connected on support; An open/close state transducing part is used to determine it " ON/OFF " state of power supply of portable phone; And a Current Control part, " ON/OFF " state that is used for the power supply of the portable phone that predicts with " ON/OFF " state transducing part is controlled the charging current from charging current source.
Above and other objects of the present invention, characteristics and advantage become clearer by writing up of reference the following drawings:
Fig. 1 is the calcspar that expression is used for the normal charge device of portable phone;
Fig. 2 is that the normal charge device is for " opening " state and " pass " state charging current and the relation between the charging interval;
Fig. 3 is a calcspar of implementing charging device of the present invention;
Fig. 4 is the curve of similar Fig. 2, the charging current of expression embodiment and the relation between the charging interval;
Fig. 5 is the more detailed circuit diagram of expression embodiment.
In order to understand the present invention better, simply consult the normal charge device that is used for portable phone that is shown in Fig. 1.As shown, portable phone 10 is equipped with battery or similar power supply 10a and can be releasably received on the charging device 20.Charging device 20 has phone test section 22, is used to predict phone 10 and has been received charging device 20; Switch 24 is arranged, operate by the output result of test section 22; With charging current source 26.Connected when predicting phone 10, test section 22 makes switch 24 closures, and charging current source 26 is received on the power supply 10a of phone 10.Normal charge device 20 is presented constant charge current to phone 10 from its current source 26, and no matter " opening " or " pass " state of telephone power 10a how.
As shown in Figure 2, suppose that charging current and time are respectively I and T.When telephone power 10a disconnection, promptly it is in " pass " state when charging, and it uses time T
1Can be full of.Yet, when telephone power 10a at " opening " state, the part charging current is consumed in the operating current as phone 10, promptly power supply 10a is recharged with the electric current littler than the electric current of in fact being fed by charhing unit 20.As a result, power supply 10a will be filled needs time T

2, following equation is arranged so:

Consult Fig. 2-5, will illustrate that using charging device of the present invention does not have the problems referred to above.In Fig. 2-5, will be marked with identical label with the same or analogous constituent of Fig. 1 and 2, so that in order simply to avoid doing unnecessary explanation.
As shown in Figure 3, the charging device that mark is made 20A also has " ON/OFF " state transducing part 28 and Current Control part 30 except the constituent of normal charge device 20 with Fig. 1.Transducing part 28 determines that whether the power supply 10a of phone 10 is in "open" state.Current Control part 30 is connected between " ON/OFF " transducing part 28 and the charging current source 26.Current Control part 30 changes the charging current of charging current source 26 with the output of " ON/OFF " transducing part 28.

As shown in Figure 4, as telephone power 10a during in "off" state, the charging current that is fed to phone 10 from charging device 20A is I

1, as shown in Figure 4, no matter " ON/OFF " state of power supply 10a all can be full of phone 10 in the identical time.
Fig. 5 more at large illustrates charging device 20A and telephone power 10a.As shown in the figure, as the triode TR that constitutes phone test section 22
6During by the conducting of signal BATT institute, its indication is received on the charging device 20A as the battery Ba of power supply 10a.Then, the triode TR2 of formation switch 24 is switched on and charging current source 26 is received on the power supply 10a.Simultaneously, whether phone 10 sends signal PSON and gives the triode TR5 that constitutes " ON/OFF " state transducing part 28 to indicate power supply 10a at " opening " state, because the output of triode TR5 is coupled to the triode TR4 as Current Control part 30, control section 30 control makes at power supply 10 through the charging current I of terminal V and is greater than charging current at " pass " state for the charging current of " opening " state.
All in all, the invention provides a kind of charging device as can be known, can interiorly at one time be in " opening " or "off" state to the portable phone charging and regardless of the power supply of adorning in it.
It is possible making the various corrections that do not exceed its scope to one skilled in the art according to content disclosed by the invention.
