Further, described shell is additionally provided with the charging inlet for connecting power supply.
The circuit diagram of the present invention is as it is shown on figure 3, pocket lamp charging principle of the present invention is:
(1) piezo-electric generating charging:
Boosting part: the vibrating power-generation end of piezoelectric ceramic piece 14 is accessed by INPUT1, and through rectifier bridge U0 and diode D1, diode D1 is used for preventing voltage reversal, burns power supply.C1 is input capacitance, it is ensured that during switching transient, and input voltage will not decline too much, provides transient current for U2 chip SX13086 when switch every time simultaneously.C1 to pass through short lead so that it is near U2, because when exceeding the mutation current that can bear, has the sub-fraction solid-state electrician can be breakdown.Electric current flows to IN end and the EN Enable Pin of U2, the chip operation when Enable Pin driving voltage is more than 1.5V, quits work during less than 0.4V.NC end is vacant foot.Inductance L1 is used for controlling the size of input ripple current.Voltage is exported by SW, through bis-rectifications of Schottky diode D2.R1, R2 are divider resistance, by adjusting two resistances, determine final output voltage (0.6V is feedback voltage, by FB pin in the Voltage Feedback of outfan to closed-loop feedback circuit) according to formula VOUT=0.6* (1+R1/R2).Electric capacity C3 plays the effect of degree of stability feedback control loop compensating and increasing phase margin to improve loop, and Schottky electric capacity C2 is in order to eliminate the noise of circuit.
Blood pressure lowering part: the positive input terminal VIN pin of U3 chip LM2596 is accessed in input one end.Meanwhile, between the input other end and ground, access low equivalent capacity C4, and must flow through short lead so that it is near U3, because when exceeding the mutation current that can bear, have the sub-fraction solid-state electrician can be breakdown.As long as and electric capacity C4 meets its rms ripple electric current equal to load current it is prevented that there is excessive transient voltage at input, provide transient current for U3 when switch every time simultaneously.Thereafter electric capacity C4 connects the FB pin and the feed-forward capacitance C8 that are respectively connected to U3 after resistance R6 plays overvoltage protection effect; when the output voltage equivalent resistance more than 10V or output capacitance is only small, the feed-forward capacitance C8 in circuit plays the effect of degree of stability feedback control loop compensating and increasing phase margin to improve loop.FB pin is then the feedback end of U3, and this pin is in the Voltage Feedback of outfan to closed-loop feedback circuit.The OUT pin of U3 is respectively connected to provide the loop receiving diode D3 and inductance L2 and electric capacity C5 to form of path for inductive current (when the switch is closed), and output voltage is filtered improving the stability of loop by this partial circuit.For OUT outfan pin, the voltage on this foot can be changed between (+VIN-VSAT) and-0.5V (about).Finally, ON/OFF pin is the Enable Pin of this chip, and when being linked into low level, chip is started working, therefore is directly connected to GND herein.
(2) electromagnetic conversion TRT: adopt coil cutting magnetic induction line generating-charging, the boosting of this module is identical with piezo-electric generating principle with blood pressure lowering part, is distinctive in that input difference, and the produced electricity of coil cutting magnetic induction line is by INPUT2 input circuit.
(3) conventional power source charging: being inputted 220V exchange by INPUT3, one end is through a diode D4, and by halfwave rectifier, the other end, after protective resistance R5, is filtered by electric capacity C6.Diode D5, electric capacity C7, resistance R4, constitute a high pressure absorbing circuit, when switching tube Q1 is disconnected, being responsible for the induced voltage on absorbing coil, causing punch through thus preventing high pressure to be added on switching tube Q1.When primary side winding ceaselessly break-make, the magnetic field of change will be formed in switch transformer, thus producing induced voltage in secondary windings.R3, for starting resistance, provides the base current started to switching tube Q1.R8 resistance below Q1 is current sampling resistor, becomes voltage after electric current is sampled.Voltage, after diode D6, adds in the base stage of audion Q2.When sampling voltage is approximately greater than 1.4V, when namely switching tube electric current is more than 0.14A, audion Q2 turns on, thus the base voltage by switching tube Q1 drags down, thus collector current reduces, thus limits the electric current of switch, it is prevented that electric current is excessive and burns.The rectified diode D7 rectification of induced voltage of transformator sampling winding, forms sampling voltage after electric capacity C11 filtering.Sampling voltage, after 6.2V Zener diode D8, adds to the base stage of switching tube Q1.When output voltage is more high, so sampling voltage is more negative, when bearing after to a certain extent, 6.2V Zener diode D8 is breakdown, thus the base potential by switch Q1 drags down, this is by causing switching tube to disconnect or postponing the conducting of switch, thus controlling energy input in transformator, also the rising of output voltage is just controlled, it is achieved that the function of voltage stabilizing output.And resistance R9 is with the electric capacity C10 of series connection, then it is positive feedback branch, from sampling winding, takes out induced voltage, be added in the base stage of switching tube, to maintain vibration.Voltage, through secondary windings, by diode D9 rectification, exports the voltage of 5V after electric capacity C9 filtering.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in reader understanding's principles of the invention, it should be understood that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete deformation and combination without departing from essence of the present invention according to these technology disclosed by the invention enlightenment, and these deformation and combination remain in protection scope of the present invention.
