1st, operation principle explanation.

Integrated oscillating unit has been connected in an oscillator with 555 integrated circuits, it controls interface unit, makes interface unit In play interface the collector of triode generate height and convert, closed so as to which two triodes in charhing unit be controlled to be formed With open-minded, when 555 integrated circuits output for it is high-order when, trigger the triode ON that interface acts on, current collection extremely low level, The bias current passage of charhing unit is formed, charhing unit is open-minded, charges to pond is electrically charged, and when 555 integrated circuits export low level, rises The triode cut-off of interface effect, charhing unit bias current passage disappear, and charhing unit is closed, and stop charging.

And in integrated unit, add duty cycle adjustment, adjust and coordinate with frequency, can adjust its output it is high-order with it is low The time of position that is to say that the triode for having adjusted interface effect opens the time with cut-off, be applied in charhing unit, become and fill The electric time is with stopping filling the time.

Two triodes in charhing unit charge by special parallel way to pond is electrically charged.Usually there was only battery charger Make pipe work, backup pipe dormancy, after charging work pipe damages, backup pipe is substituted immediately, is filled instead of instrumentation tubes to pond is electrically charged Electricity.

When being electrically charged pond and being not in contact with, battery contact shows that the contact indicator light in branch does not work, because the part The electric current of instruction is derived only from battery when not plugging alternating current.Pond is electrically charged at this point, instruction user should be clipped.

After battery is fully charged, after the side pressure of battery is more than the starting value terminated in sampling unit, terminates sampling unit and open Mobile interface unit, charge closing unit.At the same time, the process indicator light in process indicating member（2.2 in Fig. 1）It will be formed Power channel, thus at the end of process indicator light it is bright for length, and in charging process, with the height for the triode for playing interface It is low conversion and it is glittering.

After charging, charhing unit is closed, at this time connected trickle resistance（3.8 in Fig. 1）It is carried to pond is electrically charged For the tiny stream electric current of required maintenance.

2nd, line feature is analyzed.

（1）, charhing unit work characteristics.

A, the composition of charhing unit and the main idea of formation justice.

Have maintenance statistics, be exactly to perform Push And Release in this charge circuit for most fragile elements in all chargers Triode.So having carried out emphasis processing to the point in the present invention, which also becomes the important core of the present invention The heart.

Charhing unit is managed by operating circuit, fallback circuit, compensation（3.3 in Fig. 1）Composition.

Fallback circuit is managed by backup（3.21 in Fig. 1）, backup bias current diode（3.22 in Fig. 1）, backup bias current electricity Resistance（3.23 in Fig. 1）Composition；Operating circuit is by instrumentation tubes（3.11 in Fig. 1）, work bias current diode（In Fig. 1 3.12）, work biasing resistance（3.13 in Fig. 1）, work isolating diode（3.15 in Fig. 1）Composition.

The emitter of instrumentation tubes and backup pipe all connects rectification output, and the anode of work bias current diode connects the base of instrumentation tubes Pole, the cathode of work bias current diode connect work biasing resistance to ground wire, and the anode of backup bias current diode connects the base of backup pipe Pole, the cathode of backup bias current diode connect one end of compensation pipe, compensate another termination backup biasing resistance of pipe to ground wire, work The collector of pipe connects work isolating diode to the other end of compensation pipe, and the collector of the collector and backup pipe of instrumentation tubes is connected on Together, it is the output of charhing unit.

They why a most important core in this measure.After its reason present invention devises such circuit, from logical The instrumentation tubes at the beginning of electricity back up " dormant state " that Guan Ze is in open circuit just always in the working condition opened, once When charging work pipe is damaged and is stopped, backup pipe will automatically engage work, therefore greatly improve the service life of charger.

B, the reason for generating Unit two " work works with backup formula " is analyzed.

After instrumentation tubes, which work, to be turned on, since collector has high-order output, height is at this moment become by the isolating diode that works Position, but because the base stage to backup pipe passes through compensation pipe to the cathode of work isolating diode, the cathode for the isolating diode that works It is connected to backup biasing resistance（3.23 in Fig. 1）, compensation pipe is again there are pressure difference, so can be to compensation pipe closure door.It causes to back up Pipe is without bias current, and for collector by no current, the state in idle does not generate electrical wear.After instrumentation tubes are damaged, collector It is weak without output or output, closure door will not be generated, at this moment backup pipe is there will be bias current, and outside output current, realizes normal immediately Automatic switchover.Therefore charger will not be scrapped.Thus greatly increase the reliability of charger.

It should additionally illustrate at 2 points, when since the service life of triode in theory is very high, but the life of triode in itself Production process and charger on the make to welding of triode etc. the reason for or improper factor in use, often Often be challenged the service life as triode, such requirement be not achieved, and it is such change jobs earnestly automatically, be exactly to this Kind triode is not achieved one kind of high life and makes up.Second is that since two transistor parameters are consistent, when work be at opening with The on off state of disconnection, so either instrumentation tubes work or the work of backup pipe, so entire charging will not become Change.Third, using a pipe（Backup pipe in the present invention）For dormancy shape, the power consumption of the pipe is approximately zero, and the triode service life There is very big relation with its power consumed, so be hardly damaged, and than connecting work using simple parallel relationship with two pipes Make good reliability much.

（2）, integrated oscillating unit the characteristics of illustrate.

The characteristics of unit is to be not only a clapp oscillator, is also devised with frequency and duty cycle adjustment electricity in the line Road.

Integrated effect of the oscillating unit in this measure is, by the triode for playing interface（5.1 in Fig. 1）Control Charhing unit is controlled, and the form of charging is made to become the form of pulse charge.And realize the adjusting of frequency and duty cycle.Make charging Overall process, realize again charge with stop the process filled, remain optimal distribution.

The unit is by 555 integrated circuits（6.1 in Fig. 1）, charging paths, discharge paths, integrating capacitor（In Fig. 1 6.6）Composition.

Charging paths are by charging adjustable resistance（6.2 in Fig. 1）With charge protection resistance（6.3 in Fig. 1）It is in series； Discharge paths are by electric discharge adjustable resistance（6.5 in Fig. 1）With discharge prevention resistance（6.4 in Fig. 1）It is in series.

Since the equivalent charging resistor of integrating capacitor is that charging paths the sum of are connected with discharge paths, so the charging time It is long, and discharge paths resistance value is small, so the circuit and correlation unit of the present invention match very much, while can realize fine adjustment.

Forming the principle of vibration is, after energization, because integrating capacitor（6.6 in Fig. 1）Underfill electricity, so 555 is integrated Circuit（6.1 in Fig. 1）Power end by charging of the charging paths to integrating capacitor, low triggering end is low level, becomes vibration First half cycle.After the voltage of integrating capacitor is charged to the current potential of the threshold values of high-triggering end, the discharge end output of 555 integrated circuits Low level, integrating capacitor can only be by discharge paths to 555 IC interior discharge tubes（The discharge end of 555 integrated circuits）It puts Electricity.In this measure, charge constant is big, and discharge time is small, so 555 ic outputs are in the high-order time It is long, by the triode for playing interface（5.1 in Fig. 1）Reverse phase, the reverse phase of the triode by playing interface, rise connect The time of the collector low level of the triode of mouthful effect is long, and the high-order time is short, such distributional effects into charhing unit, What is formed is that the charging time is long and stop filling the time short.Also because, charging adjustable resistance long to the integrating capacitor charging time（In Fig. 1 6.2）It is related to frequency of oscillation, and is related to duty cycle, so charging adjustable resistance becomes " big to adjust ".Otherwise integration electricity The electric discharge adjustable resistance of the discharge paths of appearance（6.5 in Fig. 1）Become frequency and " ditty " of duty cycle adjustment.Also it is because upper Reason is stated, " big to adjust " and " ditty " can be passed through, it is possible to opposite maximum is scientific to be realized to the charging for being electrically charged pond and is filled Discharge maintenance effects.

（3）, interface unit explanation.

Interface unit is by playing the triode of interface（5.1 in Fig. 1）, two charge control diodes（In Fig. 1 5.5, 5.8）, interface diac（5.9 in Fig. 1）, interface triggering resistance（5.3 in Fig. 1）Composition.

Playing the triode of interface has following effect：

First, forming the impulse form of charhing unit, when integrated oscillating unit, which exports height, to be converted, interface effect has been triggered In opening and ending, current collection extremely just converts triode, when the output of integrated oscillating unit is low level, plays interface When the current collection of triode is extremely high-order, its high pressure passes through two charge control diodes, and the base stage for making the backup pipe of instrumentation tubes is inclined Stream cut-off, can not form passage, and therefore, charhing unit is closed.When the output of integrated oscillating unit is a high position, play interface The current collection of triode extremely low level when, charhing unit normal work, charge to being electrically charged pond.

Second is that as the finishing control pipe of charhing unit, after battery is fully charged, terminates sampling unit and start, make 555 collection High-triggering end into circuit is always high pressure, integrates oscillating unit output low pressure, and the collector for playing the triode of interface has High pressure exists, charge closing unit.

Third, excitation process indicator light, when serve the current collection of triode of interface it is extremely high-order when, process indicator light without Current channel over the ground, process indicator light do not work, and when the current collection extremely low level for the triode for playing interface, process indicator light is over the ground Current channel is formed, process indicator light is bright, so process indicator light is glittering process in charging process, when charging terminates Afterwards, the triode for playing interface is triggered by sampling unit is terminated, so process indicator light length is bright.

（4）, complete charge explanation.

Terminate sampling unit by sampling the upper resistance of adjustment partially（7.1 in Fig. 1）, inclined protective resistance in sampling（In Fig. 1 7.2）, sampling lower inclined resistance（7.3 in Fig. 1）, starting diode（7.5 in Fig. 1）Composition.

Sampling branch at the end of being constituted by inclined protective resistance, sampling lower inclined resistance in the upper resistance of adjustment partially of sampling, sampling Road forms sampling value, and after battery is fully charged, the side pressure of battery is more than this sampling value, makes integrated oscillating unit failure of oscillation, output Low level, the current collection for having made the triode of interface effect is extremely high-order, charge closing unit.

Sampling adjustable resistance can adjust the sampling voltage of sampling, and it is to sampling adjustable resistance most to sample protective resistance Small value is limited, so will not generate excessive deviation in debugging process.It is thus easy to adjust, start reliable.

The present invention has the advantages of prominent after implementing：

1st, it is service life for substantially increasing charger by the present invention one, reduces the scrappage of charger, second is that being electrically charged pond Science charging is realized, maintenance is enhanced, extends the service life for being electrically charged pond, reduce scrappage.And both products, no matter It is chargeable battery or mating charger, is all the commonly used species of the modern life, so the ring of two kinds of products can be enhanced It protects.Environmental protection is without minor matter, so the present invention has positive effect.

2nd, the present invention also has important economic value, for the value of common electronic product, such as this kind of production of charger Product, under no valuable first material, main points：First is Value of Science ＆ Technology, second be manually plus expense, the 3rd be only element into This, and the increased element of present invention institute is limited.After the present invention is implemented, it can be clearly felt that after user：First, the charger service life Extension, second is that be electrically charged the pond service life extension, third, significant change will not occur for capacity, therefore society is bound to receive, and recognizes Its scientific value, therefore this excellent product can replace the product of inferior quality.Since in the modern life, the product purpose is extremely general Time, so significant economic value can be generated.

3rd, due to that using the charging modes for filling, stopping, many batteries can be carried out with the maintenance of science, particularly to acid battery Etc. a major class battery, science charging has a significant impact to the service life of battery with capacity, so it is online also have as argument, very More batteries are not damaged, but are filled this bad saying, so many advanced electrical appliances, clearly propose to used The charger of battery specialty charges.

4th, each unit is connected science, and has accomplished comprehensive utilization, thus circuit is simplified, reliability is high.

5th, easily production, easily debugs, is well suited for Micro-production.
