Description
Technical field
The utility model relates to supply unit, especially relates to a kind of charging device.Be applicable to the charging of portable electron device battery.
Background technology
In current this digital times, portable digital equipment such as digital camera, Digital Video, PDA, MP3, game machine etc. are quite universal, and brand is many, and type is assorted has made us too plenty for the eye to take it all in.Though the battery as consumptive material equally also is multifarious, but has a lot of general character.For example the electric core type of the battery of different model use is identical, and capacity is close etc.This specific character a kind of for we develop " general-purpose " charger provides foundation, allows it can be to the battery charge of most portable digital equipment.
Traditional battery charger, its charging object is a kind of battery of model often, as needing to buy several different battery chargers to the battery charge of different model.Particularly, then need a kind of charging device of special use for charging electrode and the not shared rechargeable battery of sparking electrode.
Summary of the invention
The purpose of this utility model is, provide a kind of can be for different model, electric core type, capacity is identical or the charging device of close battery charge.
For achieving the above object, the utility model adopts following technical scheme: a kind of battery charger, and it comprises the charging main body of input ac power, output low-voltage dc power supply; With the control adjustment circuit in the charging base that is electrically connected of charging main body; Be installed in the removable battery case of the contact of charging having on the charging base.
Described control is adjusted circuit and is comprised the input circuit that can insert low-voltage dc power supply, connects linear adjustment circuit and charging output circuit successively, and draws and take back the linear feedback control circuit of adjusting circuit from output circuit.Input circuit, linear adjustment circuit and output circuit, and feedback control circuit is combined on the interior circuit board of charging base.
Have a pair of when battery case and charging base combination in the described battery case, can connect control respectively and adjust the charging contact of the output circuit output of circuit, one of them charging contact is the flexible member that can contact with the charging positive pole at center, battery top that is installed in battery case one end, and another charging contact can be designed to be installed in the flexible member that can contact with the charging negative pole of outer ring, battery top of the same end of battery case.
Use the technical scheme advantage of the utility model charging device as follows:
1. use the battery of different model, then only need to buy a cover charging main body and a charging base, and the corresponding battery box, reduce expenses.
2. can be for charging anodal and charging the battery charge of negative pole at same end.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is the functional-block diagram of the utility model battery charger.
Fig. 2 is that the circuit theory schematic diagram is adjusted in the control of the charging base of the utility model battery charger.
Fig. 3 is the charging base of the utility model battery charger embodiment and the element schematic diagram of battery case combination.
Embodiment
The battery of different model just has different external forms and connecting mode, how their compatibilities are got up? we have expected solving this problem with the mode of changing battery case.The battery of different model just, the battery case that adapted is different, but its charging main body is constant with charging base, if the guest has the battery of two kinds of different models, then only needs the battery case of a charging base of purchase and two correspondences.Also saved the space when comparatively speaking, having saved spending.And for the special little or especially big battery of capacity, the electric parameter of our main body as long as change is charged, the battery case of adapted correspondence gets final product as the charger of special use then.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in Figure 1, this battery charger comprises the charging main body of input ac power, output low-voltage dc power supply; With the control adjustment circuit in the charging base that is electrically connected of charging main body; Be installed in the removable battery case of the contact of charging having on the charging base.
Control in the described charging base is adjusted circuit and is comprised the input circuit that can insert low-voltage dc power supply, connects linear adjustment circuit and charging output circuit successively, and draws and take back the linear feedback control circuit of adjusting circuit from output circuit.Its circuit theory schematic diagram is seen Fig. 2.Described input circuit, linear adjustment circuit and output circuit, and feedback control circuit are on the circuit board 3 of aggregate erection in charging base.
As shown in Figure 3, charging base also comprises: loam cake 1 and lower cover 2, and be fixed on connecing on the circuit board 3 from contact plate 5 of output circuit output etc.
In Fig. 3, have a pair ofly when the combination of battery case and charging base in the battery case, can connect the charging contact that the output circuit output of circuit is adjusted in control in the charging base respectively.One of them charging contact is the flexible member 11a that can contact with the charging positive pole at center, battery top that is installed in battery case one end, and another charging contact is the flexible member 11b that can contact with the charging negative pole of outer ring, battery top that is installed in the same end of battery case.Battery case also comprises: battery bracket 7, protective cover 8 and the protective plate 9 of carrying rechargeable battery, the spring leaf 10 that is electrically connected with the charging contact etc.
