Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, the present invention comprises that by the electric main charging circuit holding power generation circuit that holding power generation machine, rechargeable battery pack are formed and single channel, the multichannel lighting load of being controlled by lighting switch constitute.The output of switch transformer B1 meets rechargeable battery pack EC in the holding power generation circuit through the resistance R 23 and the diode D12 of serial connection in the electric main charging circuit, and the voltage stack output of the output voltage of generator M1 and rechargeable battery pack EC connects the charging output.
The holding power generation circuit is made of rechargeable battery pack EC and the emitter follower that the holding power generation machine M1 that comprises gear train, holding power generation machine M1 output insert, and also inserts isolating diode D11 between holding power generation machine M1 output and the rechargeable battery pack EC.
Before to mobile phone or the charging of other digital products, to plug with the supporting data connecting line of this digital product earlier, the other end inserts the USB universal standard port of this charger, the remaining voltage of battery that be recharged product this moment can pass through resistance R 13, the LD1 discharge, detection indicator light LD1 on the charger should be lighted, if do not work, then be that battery polar is anti-phase, the changeable K1 of polarity reversing switch once if also do not work, then is provided with anti-reverse charge road in this product, can lead to alternating current or holding power generation, if the polarity reversing switch correct position is recharged should the be activated flicker or lighted of charged state indicator light on the product or character, can charge normal this moment.
As shown in Figure 1, the electric main charging circuit has adopted the high efficiency high frequency transformer, and adopts the voltage stabilizing circuit of being made up of diode D5, resistance R 3, has saved photoelectrical coupler that existing charger has etc., makes the more succinct economy of circuit.Behind the logical upward 220V electric main of ac power plug, through diode D1 rectification, capacitor C 1 filtering, the elementary c utmost point of delivering to switch generator triode T1 around L1 through switch transformer B1, circuital current is given starting resistor of the b utmost point of triode T1 again through resistance R 4 when giving the power supply of the triode T1c utmost point, capacitor C 4, resistance R 5, diode D4 forms anti-jamming circuit, resistance R 3 is the biasing resistor of the triode T1b utmost point, when triode T1 starts conducting, also there is electric current to flow through on the L1, be coupled through switch transformer B1, also obtain induced voltage on the L2, this voltage is by resistance R 6, capacitor C 3 is added to the b utmost point of triode T1, make and flow through bigger electric current among the L1, induce bigger electric current among the L2 again, triode T1 enters saturation condition, after this voltage on the capacitor C 2 passes through L2, resistance R 6 discharges, the triode T1b utmost point negative pressure of getting back, feed back through L2, triode T1 enters cut-off state again, triode T1 enters into the switch oscillatory regime so repeatedly, L1, the electromotive force that induces on the L2 is coupled to secondary L3, alternating voltage on the L3 is through diode D6 rectification, capacitor C 5 filtering, diode D5, capacitor C 2, the clamper voltage stabilizing of resistance R 3, obtain a direct voltage about 7.5V, give IC 8. pin charging, this voltage is through resistance R 10 simultaneously, resistance R 11 provides a bias voltage for the triode T2b utmost point, and triode T2 realizes the control to charged state for charging isolation drive triode.Composition battery protecting circuits such as IC1 and triode T2 can prevent the battery poor efficiency that over-charging of battery causes, even blast, on fire '.IC1 when charging 1. pin be low level, make triode T2 conducting, triode T2c utmost point output voltage is given behind K1 and is recharged the device charging.There is electric current to flow through in R13, LD1, resistance R 15, the resistance R 16 at this moment, 2. the voltage of pin is because the clamper of LD1, resistance R 13, be fixed in 2V, play the effect of base position, 5. 6. 7. pin and peripheral circuit are formed charging indication to IC1,7. the indication charged state of promptly glimmering of the high-low level charging indicator light about pin output 1Hz, when being recharged the pond and being full of, IC1 is when 3. pin is higher than 4.15V, when 3. 2. the pin level was higher than pin, 1. the pin level was that redirect is a high level, is full of indicator light LD3 and is lighted through resistance R 9, the charged state indicator light extinguishes, and the AC charging process finishes.In to the external connection electrical apparatus charging, resistance R 23, diode D12 gives chargeable battery group Ec with the voltage of switch transformer output and charges, M1 is a generator, the tooth bar that carries on the grip handle moves through tooth bar with grip and is delivered to driven gear, drive it and do the circumference rotation, again this is rotated through gear graduation and be delivered to the generator M1 main shaft that is positioned at the housing middle part, generator M1 obtains about 950 rev/mins rotating speed, its output produces the voltage of a 8.5V 300mA, give battery pack Ec charging through diode D7-D10, diode D11 is an isolating diode, its effect is to guarantee only to charge to Ec when AC charging, and not anti-D7-D10 and the M1 of being charged to, this voltage is given triode T3 by resistance R 19 again, the T4 base stage provides bias current, make triode T3, the T4 conducting, the voltage of generator and the stack of the voltage on the Ec are exported through the triode T4e utmost point, to the output that charges, capacitor C 7 is a delay capacitor, its effect is when holding power generation, because generator only carries out one-way movement, capacitor C 7 can continue to triode T3 when generator low speed, T4 provides bias current, and the voltage on the Ec makes charging current invariable always.When AC charging, because the triode T4b utmost point does not have bias current, triode T4 can also prevent counter filling.
The operation principle and the signal flow of emergency lighting are the operation that the voltage on the Ec can carry out single lamp, three lamps and close through K switch 2 conversion.Single lamp is that voltage is delivered to K switch 2 upper contacts and through diode D13, resistance R 21 LD5 lighted, and diode D14 ends; Three lamps are that voltage is delivered to the K2 lower contact through diode D14, D15, resistance R 20-R22, and LD4, LD5, LD6 are lighted, and LD4, LD5, LD6 are the diode of high brightness luminescent; Resistance K2 is middle for closing shelves.During battery Ec low-voltage, by the generating of holding power generation machine, all right electric energy supplement in real time, the electricity that it sends is directly delivered to K switch 2 through diode D7-D10, D11 and is realized illumination functions.
