The technical scheme that its technical problem that solves the utility model adopts is: design a kind of mobile phone backup power equipment, comprise circuit conversion chip and the backup battery that is connected with this circuit conversion chip one end, and the backup battery case that is used to load backup battery, the other end of described circuit conversion chip is connected with the mobile phone main battery, the circuit conversion chip is integrated on the mobile phone main circuit board and by four communication interfaces and is connected with the mobile phone master controller, this communication connects based on the I2C universal serial bus, comprise two holding wires, one is two-way data wire SDA, and another root is clock line SCL.Increase by 2 interrupt signal lines again, be INT-IN and INT-OUT, when new informational needs transmits, send signalisation as prompting with them, 2 interrupt signal lines of this of increase also can make microcontroller be reduced to minimum power modes and dwindle the standby power consumption amount.Guarantee that system has best operating state and natural user-friendly interface.Described circuit conversion chip is used to detect battery types, electric weight; Control battery charge or discharge.
As the further improvement of above-mentioned technology, above-described a kind of mobile phone backup power equipment, described circuit conversion chip are connected to the positive pole of mobile phone main power source by a protective circuit.Provide and comprise defencive functions such as short circuit, both positive and negative polarity reversal connection, overtension, temperature be too high, overtime.
As the further improvement of above-mentioned technology, above-described a kind of mobile phone backup power equipment, described backup battery are dry cell or rechargeable battery.
As the further improvement of above-mentioned technology, above-described a kind of mobile phone backup power equipment, described backup battery are single or several No. 5 or No. 7 batteries.
As the further improvement of above-mentioned technology, the resistance of battery contact piece is less than 4 Europe in the above-described a kind of mobile phone backup power equipment, described backup battery case.
As the further improvement of above-mentioned technology, above-described a kind of mobile phone backup power equipment, mobile phone backup battery and backup battery case are arranged on bottom, back or the side of mobile phone.
In addition, can print the reserve battery icon on the described reserve battery case.Described backup power equipment can be applicable to other and moves on the portable terminal device.
Implement a kind of mobile phone backup power equipment of the present utility model, have following beneficial effect:
1, obtaining conveniently of reserve battery easily, and is easy to carry.
2, can prolong the stand-by time of mobile phone, the user is without fear of an attack from the rear.
3, structural design exquisiteness of the present utility model under the state of having kept the original volume of mobile phone substantially, has increased the function that reserve battery provides electric energy.
4, has ultralow standby power consumption.
5, when reserve battery is rechargeable battery, can make the user not need to use separately charger that reserve battery is charged simultaneously to main power source and reserve battery charging, convenient for users to use.
6, provide and comprise defencive functions such as short circuit, both positive and negative polarity reversal connection, overtension, temperature be too high, overtime.
7, have simple, natural user interface, the use stand-by power supply of nature under the user's manual situation is not being browsed at the family of guaranteeing.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the program flow diagram of a kind of mobile phone backup power equipment of the utility model;
Fig. 2 is the structural representation of a kind of mobile phone backup power equipment embodiment of the utility model.
Among the figure: 1. main battery covers, 2. mobile phone main battery, 3. main frame, 4. backup battery lid, 5. cathode spring, 6. backup battery case, 7. anode electrode film.
Embodiment
As Fig. 1, shown in Figure 2, in the embodiment of a kind of mobile phone backup power equipment of the utility model, comprise circuit conversion chip and the backup battery that is connected with this circuit conversion chip one end, and the backup battery case 6 that is used to load backup battery, the other end of described circuit conversion chip is connected with mobile phone main battery 2, the circuit conversion chip is integrated on the mobile phone main circuit board and by four ultralow energy communications interface and is connected with the mobile phone master controller, this communication connects based on the I2C universal serial bus, comprise two holding wires, one is two-way data wire SDA, and another root is clock line SCL.Increase by 2 interrupt signal lines again, be INT-IN and INT-OUT, when new informational needs transmits, send signalisation as prompting with them, 2 interrupt signal lines of this of increase also can make microcontroller be reduced to minimum power modes and dwindle the standby power consumption amount.Guarantee that system has best operating state and natural user-friendly interface.
The circuit conversion chip is used to detect battery types, electric weight; The charge or discharge of control backup battery.When the main battery electric weight is not enough, whether the circuit conversion chip at first detects backup battery is rechargeable battery, if rechargeable battery, then can directly charge to main battery, if not rechargeable battery, then point out the user, (such design is to selection of user whether to begin charging, whether need and make things convenient for buy reserve battery again) if considering, if the user selects not charge, mobile phone shuts down because of electric weight is low, and reserve battery will provide enough electric weight to mobile phone (if inner adorned a new dry cell), so that the user arbitrarily opens mobile phone automatically.The circuit conversion chip also can detect the reserve battery electric weight, so that the user in time changes battery or charging.
The circuit conversion chip is connected to the positive pole of mobile phone main power source by a protective circuit.Provide and comprise defencive functions such as short circuit, both positive and negative polarity reversal connection, overtension, temperature be too high, overtime.
Backup battery 1 is dry cell or rechargeable battery.When backup battery is rechargeable battery when mobile phone is charged, can be simultaneously to backup battery and main battery charging.When backup battery is non-rechargeable battery when mobile phone is charged, system will remind, and can not charge, and the prompting user takes out the non-rechargeable battery in the reserve battery case.
In the present embodiment, mobile phone backup battery and backup battery case 6 are arranged on the bottom of mobile phone.Backup battery in the backup battery case 6 is single No. 7 batteries.The resistance of battery contact piece is less than 4 Europe in the backup battery case 6.Resistance is more little, can make the energy of reserve battery obtain better utilization.Cathode spring 5 in the backup battery case 6 and cathode conductor together are locked on the backup battery lid 4.Cathode spring 5 can be done with having high conductivity and good pliability lead or copper, make it continue to be connected with PCB, cathode spring 5 adopts the bigger spring of backhauls, because of the spring of big backhaul can block battery in the maximum allowance scope, the scope of application of increase reserve battery case 6.
On reserve battery case 6, print the reserve battery icon, be convenient to User Recognition.
Backup power equipment described in the utility model also can be applicable to other and moves on the portable terminal device, for it is provided convenience, and the lasting reserve energy.
In sum; as those of ordinary skill is scrutable in the art; described in this specification is a preferred embodiment of the present utility model, and all change or modifications of making according to design of the present utility model all should be in claim protection range of the present utility model.
