Abstract
The utility model relates to an automatic cut-off charger, comprising an outer shell and internal circuits. The internal circuits are divided into a charging circuit, an automatic cut-off circuit and an emergency lighting circuit. One-time alternating current is used for charging an accumulator jar after depressurization and rectification. After the accumulator jar is charged fully, the forward bias value of controlled silicon SCR-[2] is conducted, the controlled silicon SCR-[1] of the charging circuit is cut off, and the aim of automatically stopping charging is obtained. The emergency lighting circuit is added in the circuits, and when the one-time alternating current is cut off suddenly, the accumulator jar supplies electricity to a lighting lamp to obtain the aim of emergency lighting. The utility model has the advantages of reasonable structure, wide application, various functions and easy production.
Description
The utility model relates to a kind of auto-cut-off type charging, lighting device, is applicable to the occasion of various storage battery chargings and emergency lighting.
In the prior art, general charger all can not cut off the power supply automatically, causes storage battery to overcharge easily and damages, and also causes energy waste easily.
Task of the present utility model is to design a kind of charging device that can cut off the power supply automatically and can open emergency light automatically, and the key that realizes above-mentioned task is to be provided with the automatic power-down circuit of being made up of controllable silicon and resistance, electric capacity and diode in circuit.
Accompanying drawing 1 is an auto-cut-off type charging device circuit diagram.Accompanying drawing 2 is outage charging automatically, emergency lighting device circuit diagram.
By reference to the accompanying drawings, narrate content of the present utility model:
The utility model is made up of shell and internal circuit, and internal circuit is by charging circuit, and power-down circuit and emergency lighting circuit three parts are formed automatically.
Show that as Fig. 1 charging circuit is mainly by controllable silicon SCR, diode D1, D2, resistance R 0 are formed, and an alternating current is through 0 pair of storage battery E charging of resistance R.Automatically power-down circuit mainly is made up of controllable silicon SCR 2 and diode D1, D2, D5, capacitor C 1, resistance R 1-R5, after storage battery E is full of electricity, pressure drop on the potentiometer R4 increases to is enough to make diode D5 to puncture, voltage on the resistance R 5 makes controllable silicon SCR 2 positively biased value conductings, through resistance R 1 and R2 dividing potential drop, it is original about 1/2 that f point current potential is reduced to, and causes controllable silicon SCR 1 to be ended, and reaches charging and finish and automatically shut down the purpose of electric current.The capacitor C 1 main cushioning effect that rises.
Fig. 2 is that outage is charged and the emergency lighting device circuit diagram automatically.This circuit adds the lighting loop of opening automatically, break in circuit shown in the accompanying drawing 1, when an alternating current charges to storage battery, lighting loop ends, after the storage battery charging finishes, if when an alternating-current power supply is still powered, still not conducting of lighting loop, have only when an alternating-current power supply is stopped power supply, the conducting of control silicon SCR5 positively biased value, Chuan Lian illuminating lamp DD is bright with it, when AC power restores electricity, controllable silicon SCR 5 produces oppositely value partially, and illuminating lamp DD goes out, and diode D4 plays rectified action, electric capacity R6 and R7 are divider resistance, 2 cushioning effects of capacitor C.
Compare with prior art, the utlity model has rational in infrastructure, can cut off the power supply automatically, thereby can not damage the advantage of storage battery because of overcharging, in charging circuit of the present utility model, also can add the emergency lighting circuit, make the utility model have charging simultaneously, cut off the power supply automatically and multiple function such as illumination.
