Description
Technical field
The utility model relates to charger, particularly a kind of emergent charger for cell phone that adopts dry cell.
Background technology
Conventional mobile phone all adopts the charging of AC type charger for mobile phone, and the charger volume is big, heavy, carries extremely inconvenience, and it must do the long period charging in the place that the 220V alternating current is arranged.Not having the occasion of alternating current, as on go out long journey or field work or the vehicle that travels, is very inconvenience to the more frequent people that makes a phone call.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing AC system charger for mobile phone, provides a kind of emergent charger for cell phone that adopts dry cell, to satisfy numerous cellphone subscribers' emergent charging.
This emergent charger for cell phone, comprise: housing, dry cell, voltage-frequency-conversion circuit, booster circuit, current rectifying and wave filtering circuit and the output plug that connects battery of mobile phone by dry cell power supply, the output of voltage-frequency-conversion circuit connects the input of booster circuit, the output termination current rectifying and wave filtering circuit input of booster circuit, the output voltage of current rectifying and wave filtering circuit is received the power end and the feedback input end of voltage-frequency-conversion circuit simultaneously, and the output of current rectifying and wave filtering circuit is given charging mobile phone battery by described output plug.
Invention advantage compared with the prior art is as follows, the charger for emergency circuit working is on off state, the very little conversion efficiency of circuit loss is very high, wherein because the working power of V-F translation circuit also is to be provided by capacitor C, so even the voltage of the power-supply battery end far away, is in the operating voltage of V-F translation circuit, whole charger circuit still can operate as normal, thereby excavates electric energy when minimum (can dig 0.4V) of power-supply battery to greatest extent.For example: charger uses in common No. five of two joints the retaining dry cell to give MOTOROLA 998 cell-phone chargings two hours, and mobile phone can standby more than 24 hours.
It gives cell-phone charging with one, two joint dry cells through the electronics back of boosting, thus solved the conventional charger volume big, heavy, must charge for a long time in the fixed location etc. problem.Charger volume small and exquisite (it is so big to may diminish to lighter), in light weight, it is very convenient to carry.Bring great convenience for the user who goes on business, travels, runs professional person and outlying district alternating current charging inconvenience.The charger for emergency owner only needs can solve mobile phone and not have electric worry once, two joint dry cells when mobile phone does not have electricity.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is an embodiment circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Emergent charger for cell phone is with the electronics stepup transformer voltage of one or two batteries to be raised to cell-phone charging voltage, gives the cell-phone charging of different plates then through different cell-phone charging plugs.
As shown in Figure 1, 2, emergent charger for cell phone is made up of housing 1, dry cell, voltage-frequency-conversion circuit, booster circuit, the current rectifying and wave filtering circuit by dry cell power supply and the output plug 2 that connects battery of mobile phone, the output of voltage-frequency-conversion circuit connects the input of booster circuit, the output termination current rectifying and wave filtering circuit input of booster circuit, the output voltage of current rectifying and wave filtering circuit is received the power end and the feedback input end of voltage-frequency-conversion circuit simultaneously, and the output of current rectifying and wave filtering circuit connects described output plug 2.
Its circuit diagram 2 major parts are: voltage-frequency-conversion circuit (V-F), MOSFET pipe, rectifier diode D, accumulation of energy inductance L, filter capacitor C.Booster circuit is made up of MOSFET pipe and the accumulation of energy inductance L that is connected in MOSFET pipe source electrode, between the other end that dry cell is connected the accumulation of energy inductance L and MOSFET manage and drain.Current rectifying and wave filtering circuit is made up of diode D and capacitor C.MOSFET pipe source electrode connects the positive pole of diode D, and the voltage of dry cell is 1-3.3V, can adopt two joints No. 5 or No. 7 dry cells.Dry cell is arranged in the housing 1, and the pcb board of charging circuit places a side in the housing 1, and output plug 2 is by the output of cable connection circuit.
By the conducting of V-F translation circuit control MOSFET pipe or end, energy is stored in the inductance L when the conducting of MOSFET pipe, when the MOSFET pipe by the time inductance L produce back electromotive force, D charges to capacitor C by rectifier diode, forms high pressure.Take out voltage signal from capacitor C and feed back to the V-F translation circuit, thereby the then corresponding adjustment output frequency of V-F translation circuit has been adjusted the charging interval of capacitor C, finally obtains the needed charging voltage of mobile phone.The different cell-phone charging plug of adapted and adjust the cell-phone charging that suitable output voltage just can be given different plates again.
As long as the user carries one, two joint dry cells, just can not give cell-phone charging with charger for emergency when mobile phone has electricity, the user can be sitting in the car and charge, and charges while also can walk, charging is regardless of region and time when can also make a phone call while walking.Owing to only use one or two batteries, make the charger volume small and exquisite, in light weight, it is very convenient to carry.It is so big that the charger minimum of our invention may diminish to lighter.
