Description

Battery of mobile telephone charging timer

The utility model relates to a kind of for the battery of mobile telephone charging timer of mobile phone with battery control charging interval when charging.

Mobile phone is extensively used it.Mostly be to adopt rechargeable battery as essential battery.All use subsidiary at random special charger to carry out to battery charge is general.But these special chargers all do not have timing architecture, and most battery has strict restriction to the charging interval, and this is had only by the Artificial Control timing, and are both inconvenient, inaccurate again, in case out-of-date charging can have a negative impact to the cycle life of battery; Though at present some electronic timers are arranged, as clock-timer, Industry Control timer etc., these products are not suitable for battery charge timing usefulness, and their complex structures, cost height, troublesome poeration.

The purpose of this utility model provides a kind of novel battery of mobile telephone charging timer, can solve the timing problem of battery of mobile telephone charging easily and effectively.

The purpose of this utility model is achieved like this, in its housing, be equipped with by pulse-generating circuit, can preset and subtract the timer circuit that counting circuit, decoding display circuit, output control circuit and power circuit constitute, switch, indicator light, charger socket, ac power plug and display window are housed on the housing.

The utility model is simple in structure, and is easy to use, can protect rechargeable battery effectively, increases the service life, and because of its cost is low, volume is little, is easy to produce and apply very much.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is an outside three-dimensional structure diagram of the present utility model.

Fig. 2 is timer circuit figure of the present utility model.

Provide by Fig. 1, the utility model is to be made of housing and its internal circuit, digital display window 2, push-button switch 4, indicator light 6 are arranged on the front of housing 1, have on one side on ac power plug 3, the other side charger socket 5 is arranged, be equipped with by pulse-generating circuit in the housing 1, can preset and subtract the timer circuit that counting circuit, decoding display circuit, output control circuit and power circuit constitute.Timer circuit is provided by Fig. 2.By shown in Figure 2, its each several part circuit is constructed as follows;

Pulse-generating circuit was by integrated circuit (IC) in 1 hour ₁, resistance R ₁, R ₂, capacitor C ₂Constitute, after circuit produces vibration, through integrated circuit (IC) ₁Export hour pulse signal by 3 pin behind the frequency division, again through triode BG ₁After anti-phase, connecing (offering) can preset and subtract counting circuit IC ₂, subtract counting circuit IC ₂Preset number by push switch 4 (being AN among Fig. 2) control, whenever press once, count value just subtracts 1, simultaneously IC ₂Export 8421 yards to decoding display circuit IC ₃, P demonstrates predetermined value by display tube.After starting working, integrated circuit (IC) ₂15 pin every 1 hour the input positive pulse, pass through integrated circuit (IC) then ₃The digital demonstration of control successively decreases 1.When charactron is decremented to 0, IC ₂7 pin export a low level, through triode BG ₂Become high level after anti-phase.Triode BG ₂, BG ₃And relay J constitutes output control circuit, relay J dead electricity after triode BG3 ends, J _1-1Disconnect, charger is stopped battery charge, simultaneously, triode BG ₂The output high level is by diode D ₂, be added in IC ₁11 pin, make IC ₁The failure of oscillations, thus whole charging control regularly finished.Power circuit is by transformer T, rectifier bridge D ₁, capacitor C ₁Constitute with three terminal regulator W, output 9V direct current uses for its each circuit.J in the circuit _1-1It is a part of relay J.

State operating circuit thereon, its structure wiring is that transformer J is through rectifier bridge D ₁Connect capacitor C ₁, three terminal regulator W ₁Pin, three terminal regulator W ₂Pin ground connection, 3 pin meet IC ₁16 pin, IC ₃18 pin, IC ₂16 pin, triode BG ₃Emitter and resistance R ₇, switch AN, integrated circuit (IC) ₁11 pin connecting resistance R ₁, diode D _2,10Pin connecting resistance R _2,9Pin connects capacitor C _2,8Pin ground connection, IC ₁Through resistance R ₄Sending and receiving optical diode D ₃, meet triode BG through resistance R 5 ₁Base stage, resistance R ₃Meet triode BG ₁Collector electrode, triode BG ₂Base stage connecting resistance R ₆, collector electrode connecting resistance R ₇, diode D ₂And triode BG ₃Base stage, integrated circuit (IC) ₂Same integrated circuit (IC) ₃And triode BG ₃Join IC ₃Output meets digital display tube P.In the present embodiment, IC ₁Be MC14060, IC ₂Be MC14510, IC ₃Be MC ₁₄₅₁₃, three terminal regulator W is 7809.

When practicality, the utility model is inserted on the AC power through plug 3, charger is inserted in the charger socket 5 and gets final product.Easy to use, simple to operate, rechargeable battery there is good protective action, have great application market, remarkable in economical benefits.
