Abstract
The utility model relates to a charger indicator for a portable charging lamp, which is composed of an alarm circuit formed by resistors R1, R2, R3, a voltage stabilizing tube D1, a coms module KD and a buzzer HTD. When the lamp charging is saturated, the utility model can emit an alarm signal correctly and in time. The utility model has the advantages of simple structure, small size and low cost. The utility model can be matched with various portable charging lamp.
Description
The utility model relates to a kind of charge indication means of portable rechargeable lamp.
Existing portable rechargeable lamp is because can use by recharge, so be subjected to very much people's welcome.But the charger of this rechargeable lamp does not all have indicating device, the user often can not more correctly grasp the charging interval when charging, often cut off the electricity supply too early and cause undercharge, perhaps be in charged state for a long time, and quicken the aging and a large amount of electrolyte volatilizations of pole plate, influence the useful life of storage battery.
The purpose of this utility model is that a kind of portable rechargeable lamp charge indicator will be provided, and when storage battery was charged to saturation condition, it can correctly send alarm signal effectively.
The utility model contains resistance R as shown in Figure 1
1, voltage-stabiliser tube D
1, resistance R
2, resistance R
3, the warning circuit that constitutes of cmos module KD and buzzer HTD, the pin of described module KD (1) passes through resistance R
3Join with positive source, pin (3) is connected with power cathode, and pin (2) is connected resistance R
1With resistance R
2Between, pin (4), serial connection buzzer HTD between (5), voltage-stabiliser tube D
1One termination power negative pole, the other end are connected on KD pin (1) and resistance R
3Between, its operation principle following (rechargeable lamp with the 6V storage battery is an example); With the positive pole of the A termination storage battery of circuit, the B point connects the negative pole of storage battery, and pin (1) voltage of CMOS module KD passes through resistance R
3With voltage-stabiliser tube D
1Be stabilized in 3.6V, as the operating voltage of KD.When A point battery voltage was lower than 6V, the pin of KD (2) voltage was through resistance R
1And R
2After the dividing potential drop, less than threshold voltage, promptly KD does not work.When A point battery voltage is charged to limiting voltage 6.7V, the pin of KD (2) voltage reaches threshold voltage, make KD trigger work, by pin (4), (5) output alarm signal, and drive the buzzer sounding alarm, thus guarantee more correctly to grasp the charging interval, it is long to avoid undercharge or charging interval.
The utility model is because directly the change in voltage of employing positive and negative poles of battery is as the warning triggering signal, and is correct, reliable.And have characteristics such as simple in structure, that volume is little, cost is low, be applicable to existing various portable rechargeable lamp.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the charging indication schematic diagram of band acousto-optic amplifier.
Do further specifying of embodiment below in conjunction with accompanying drawing: the utility model comprises resistance R
1, R
2, R
3, voltage-stabiliser tube D
1, cmos module KD and buzzer HTD, the pin of described module KD (1) passes through resistance R
3Join with positive source, pin (3) links to each other with power cathode, and pin (2) is connected resistance R
1With resistance R
2Between, pin (4), serial connection buzzer HTD between (5), voltage-stabiliser tube D
1One termination power negative pole, the other end are connected on KD pin (1) and resistance R
3Between.KD can adopt KD-153H, considers that KD directly drives the warning that buzzer may send and rings inadequately, can add one again by resistance R at its output
4, R
5, R
6Triode BG
1, loud speaker Y and Light-Emitting Diode D
3The acousto-optic amplifier of forming (as shown in Figure 2), described light-emitting diode D
2And resistance R
6Be serially connected in triode BG
1Collector electrode and power cathode between, loud speaker Y and resistance R
5Be serially connected in BG
1Collector electrode and positive source between, BG
1Base stage pass through resistance R
4Be connected with the pin (4) of module KD.Alarm signal is after amplifying like this, just can be by the loud speaker bright chimes of doom that makes sound.Simultaneously, light-emitting diode D
2Also can send the index signal of flashing, make indicating effect better.
