The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of double cell power supply mobile phone, makes two batteries co-ordination when power supply, charging of mobile phone, and the assurance mobile phone is in use realized permanent standby.
Described a kind of double cell power supply mobile phone, comprise cell phone mainboard and annex, a dismountable main battery is housed in the hand set machine shell, it is characterized in that: described cell phone mainboard is provided with main battery circuit and the secondary cell circuit that is connected with the IO end of logic control device, plug-in secondary cell is provided with metal contact and passes hand set machine shell and be connected with the input electric contact piece that the secondary cell circuit is drawn, and cell phone mainboard detects the state of current supplying cell and carries out the switching of supply power mode, charging modes.
Described a kind of double cell power supply mobile phone is characterized in that: adopt voltage detection device, logic control device, load switch and transistor to constitute the diverter switch of main battery, secondary cell.
Described a kind of double cell power supply mobile phone is characterized in that: described supply power mode comprises main battery power supply, secondary cell power supply, three kinds of supply power modes of charger power supply.
Described a kind of double cell power supply mobile phone, it is characterized in that: described charging modes comprises that charger is that the charging of main battery and secondary cell, charger are four kinds of charging modes of main battery charging for secondary cell charging, secondary cell separately for main battery charging, charger separately simultaneously.
Described a kind of double cell power supply mobile phone, it is characterized in that: described secondary cell is the leather sheath battery.
The utility model double cell power supply mobile phone for mobile phone provides an extra secondary cell, provides unusual mobile phone flying power to the user on the basis of the existing main battery of prior art mobile phone.When the main battery electric weight depletes, it is low excessively that the mobile phone voltage detection device detects main battery voltage, logic control device switches to the secondary cell power supply with supply power mode, auxilliary simultaneously battery can also be the main battery charging of electric weight deficiency, solving at a pinch, mobile phone solves the inconvenience that mobile phone needs frequent charge simultaneously because of the puzzlement of the low shutdown of electric weight.If the cellphone subscriber is in an environment of being inconvenient to give cell-phone charging, he does not worry that mobile phone can not work because of electric weight depletes yet; Particularly in some important occasions, such as just in communication process, the user is not worrying that mobile phone can cause dropped calls because of electric weight is not enough yet.The utility model double cell power supply mobile phone can allow the relieved mobile phone of must being with of user go on a journey.
Description of drawings
Fig. 1 is the utility model main battery circuit;
Fig. 2 is the utility model secondary cell circuit.
Embodiment
The utility model double cell power supply mobile phone comprises cell phone mainboard and annex, a described cell phone mainboard of dismountable main battery is housed in the hand set machine shell is provided with main battery circuit and the secondary cell circuit that is connected with the IO end of logic control device, plug-in secondary cell is provided with metal contact and passes hand set machine shell and be connected with the input electric contact piece that the secondary cell circuit is drawn, and cell phone mainboard detects the state of current supplying cell and carries out the switching of supply power mode, charging modes.When normal use, power by main battery.Cross when low when voltage detection device detects main battery voltage, logic control device switches to the secondary cell power supply with supply power mode, and secondary cell charges for main battery simultaneously.When charging, main battery or secondary cell at first charge and finish, and the battery that logic control device is finished charging cuts off, continue as the uncharged battery charge of finishing.
As Fig. 1 is the utility model main battery circuit, R100, R113, R114, R115 are resistance, C101, C103-106, C138 are electric capacity, CR100 is a built-in capacitance resistance, VDD_IO is the operating voltage of logic control device, and MAIN_BAT is the main battery positive pole, and GND is the ground connection negative pole, VCHG is a charging voltage, and VBAT is the cell phone mainboard power access end.The signal controlling transistor Q100 of the VDRV end of logic control device switches on or off VCHG MAIN_BAT is charged.
As Fig. 2 is the utility model secondary cell circuit, R502-514 is a resistance, C501-C512 is an electric capacity, Cr500 is a built-in capacitance resistance, D500 is a diode, Rt500 is a voltage stabilizing didoe, Q501, Q502 are transistor, MA50 is that cmos switch, MA500 are that load switch, MA502 are charging management chip, VCHG is a charging voltage, BATAUX_CHG_EN end, SW_ONOFF end, ADCAUX end are held for the IO of logic control device, and VDD_IO is the operating voltage of logic control device, and VBATAUX is the secondary cell positive pole.The signal controlling MA502 of BATAUX_CHG_EN end switches on or off charging voltage VCHG secondary cell VBATAUX is charged.The signal controlling MA500 of SW_ONOFF end switches on or off being connected of secondary cell VBATAUX and cell phone mainboard power access end VBAT.The IN end signal control secondary cell VBATAUX of MA50 and the electric current between the cell phone mainboard power access end VBAT.
