Description
Technical field
The utility model relates to a kind of mobile phone, refers in particular to a kind of mobile phone of power saving.
Background technology
The backlight LED of mobile phone is the parts that mobile telephone power consumption is very large, in order to extending cell phone service time, saves the power consumption of mobile phone, and everybody manages in idea the power consumption reducing mobile phone backlight.Existing mobile phone backlight is generally by timing, if a period of time does not operate, closes backlight.Certain user also can positive closing backlight by pressing screen locking key.But a lot of situation is that user is not using mobile phone now, but backlight is but lit, and as mobile phone does not use, but software message pushes, and backlight is just lit, and causes the waste of electric energy, the shortening of stand-by time.
Summary of the invention
The technical problems to be solved in the utility model, is the mobile phone providing a kind of power saving, solves the problem that existing mobile phone energy consumption is high.
The utility model is achieved in that
A kind of mobile phone of power saving, comprise body, body one side has display screen, body while be provided with HOME key, BACK key and MENU key, the another side inside of body has the support column perpendicular to display screen of a hollow, one end of described support column is embedded on the shell of body, the other end of support column is connected with the probe of human body infrared inductor, interior of mobile phone also comprises power-saving circuit, power-saving circuit comprises comparator, resistance, optocoupler, the in-phase input end of comparator is connected with the output of human body infrared inductor, the inverting input of comparator is connected with comparison reference voltage, the output of comparator is connected with one end of resistance, the other end of resistance is connected with the electrode input end of optocoupler, the negative input of optocoupler is connected with power cathode, the cathode output end of optocoupler is connected with the output of backlight drive circuit, the cathode output end of optocoupler is connected with the positive pole of backlight LED, the negative pole of backlight LED is connected with power cathode.
The utility model has the advantage of: the screen of this mobile phone is when nobody sees (namely mobile phone screen does not use), just close backlight LED, greatly reduce mobile phone energy consumption, when screen has people to see, just according to normal backlight drive state, meet the demand that user uses.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical section schematic diagram of the present utility model.
Fig. 3 is the circuit diagram of the circuit in the utility model.
Embodiment
Refer to shown in Fig. 1 to Fig. 3, a kind of mobile phone saving power consumption, comprise body 1, body 1 one side has display screen 2, body 1 while be provided with HOME key (i.e. homepage key), BACK key (i.e. return key) and MENU key (i.e. Menu key), the another side inside of body 1 has the support column 3 perpendicular to display screen of a hollow, one end of described support column 3 is embedded on the shell of body 1, the other end of support column 3 is connected with the probe 4 of human body infrared inductor, interior of mobile phone also comprises power-saving circuit, power-saving circuit comprises comparator U1, resistance R3, optocoupler U2, the in-phase input end of comparator U1 is connected with the output of human body infrared inductor, the inverting input of comparator U1 is connected with comparison reference voltage, the output of comparator U1 is connected with one end of resistance R3, the other end of resistance R3 is connected with the electrode input end of optocoupler U2, the negative input of optocoupler U2 is connected with power cathode, the cathode output end of optocoupler U2 is connected with the output of backlight drive circuit, the cathode output end of optocoupler U2 is connected with the positive pole of backlight LED L1, the negative pole of backlight LED L1 is connected with power cathode.Wherein, comparison reference voltage is made the voltage that human body infrared inductor exports for comparator and being compared, and comparison reference voltage has multiple implementation, and reference voltage chip can be used to realize, or resistance R1 and resistance R2 dividing potential drop as shown in Figure 3, can be used to realize.Comparison reference voltage should not be selected too low, generally can select more than 1V's.As in the circuit of Fig. 3, if positive source is 3.7V, then resistance R1 can select the resistance of 20K, and resistance R2 can select the resistance of 10K.The power supply of comparator U1 directly can select the power supply of lithium battery.Wherein, human body infrared inductor is existing element, and it has probe, can export high level after sensing human body infrared, and do not sense then output low level, the utility model is not repeated herein.
In certain embodiments, these elements can select following model: power supply selects the 3.7V power supply of lithium battery, and comparator U1 selects TL393, and resistance R3 selects 300 Europe, and optocoupler selects PC817.The utility model in use, when face faces display screen, human body infrared can arrive on the probe of human body infrared inductor by the hollow of support column, now human body infrared inductor exports high level, and comparator U1 exports high level, then drive the light-emitting diode of optocoupler U2 inside to light, now optocoupler rear class conducting, backlight drive circuit (namely driving the circuit of backlight LED work) can driven backlight LED L1, and namely when people sees display screen, the backlight of display screen can normally work.When face leaves display screen, namely after need not seeing display screen, the probe of human body infrared inductor then cannot sense, human body infrared inductor output low level, comparator U1 output low level, optocoupler also not conducting, now backlight LED L1 is in closed condition completely, save electricity, reach the object of power saving.Support column of the present utility model can block the infrared of other positions of human body, avoids the infrared impact on probe in other positions of human body.
In certain embodiments, mobile phone of the present utility model also includes for the telecommunication circuit with base station communication.
The above execution mode, just better embodiment of the present utility model, be not limit the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should comprise in the utility model patent claim.
