Abstract

The utility model relates to a power supply device, particularly a two purposes apparatus for starting vehicle and charging with two functions of charging battery groups and starting engines of motor vehicles. It comprises a potential transformer, a charging circuit and a start-up circuit. The utility model is characterized in that the primary winding of the potential transformer is composed of two windings which can be mutually connected in series or in parallel. The two windings are connected in parallel on the occasion of start-up to meet the starting request of great current while the two windings are connected in series on the occasion of charging the battery to decrease no-load current and long time charging can decrease energy dissipation. The utility model has a reasonable structural design and saves electric energy.

Description

Motor vehicle starting charge dual-purpose machine

The utility model relates to a kind of electric supply installation, particularly has the motor vehicle starting charge dual-purpose machine to batteries charging and two kinds of functions of starter motor motor vehicle engine.

It is 90226814.7 motor vehicle charge initiation double-purpose electric source that China's utility model patent discloses a kind of application number, and it is made up of charging circuit unit and start-up circuit unit two parts.The charging circuit unit comprises main coil L ₄, iron core ₅, charge coil L ₁₀With diode D9; The start-up circuit unit comprises main coil L ₄, iron core ₅With actuating coil L ₆With diode D ₇Transformer main coil L as charging and start-up circuit unit ₄, the selection of its line footpath and the number of turn will take into account the needs that start and charge both, and requirement moment no-load current is big when promptly starting, and then requires no-load current little during charging, and therefore this power supply no-load current in charging process is bigger, wastes energy.The start-up circuit unit adopts diode D7 to carry out halfwave rectifier, and the direct current fluctuation of output is bigger, and motor car engine is had certain influence.

The purpose of this utility model is to provide a kind of motor vehicle starting charge dual-purpose machine of saving the energy.

The purpose of this utility model is achieved in that motor vehicle starting charge dual-purpose machine, comprise transformer, charging circuit and start-up circuit, its special character be the primary winding be by two can be connected in series mutually or and the winding that connects constitute, the line footpath of two windings, internal resistance, the number of turn are all identical, be connected with change over switch between two windings, realize and connect or be connected in series by change over switch.When being used for the starter motor motor vehicle engine, can and connect, satisfy big current start requirement two elementary windings.Be used for when charge in batteries, two windings serial connection can be reduced no-load current as far as possible, long-time charging can reduce loss, saves electric energy.The transformer secondary output winding is to constitute with the segmentation winding serial connection that has tap by starting winding, starts winding one end and is connected with the input of rectification circuit, and the other end is connected with another input of rectification circuit through circuit changing switch, constitutes start-up circuit.By starting winding and the transformer secondary output charging winding that constitutes with segmentation winding that it is connected in series mutually, it starts winding one end and is connected the charging adjusting change over switch K that links to each other with segmentation winding centre cap with rectification circuit input end ₃Through ammeter, circuit changing switch K ₂Be connected with another input of rectification circuit, constitute charging circuit.This charging circuit can be exported the magnitude of voltage of one or two or more kinds, to satisfy the requirement of dissimilar storage batterys, enlarges its scope of application.

The utility model compared with prior art has following characteristics:

1, reasonable in design is saved electric energy.Utilize two can go here and there mutually or and the primary winding that connects, when starting, with two elementary windings and connect, satisfy the requirement of big current start.During charging, with two elementary winding serial connections, can reduce no-load current, long-time charging can reduce energy loss.

2, adopt full-wave rectification, can export direct current more stably.

3, as starting power supply, not only start easily, not influenced by cryogenic conditions, and can save storage battery.

4, the voltage of charging circuit output can be regulated, and can satisfy the requirement of different capabilities storage battery.

Fig. 1 is circuit theory diagrams of the present utility model.

Be described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, the utility model mainly is made up of charging circuit (1), start-up circuit (2) and transformer B, and the elementary winding of transformer B is by two line footpaths, internal resistance, winding L that the number of turn is all identical _1-1, L _1-2Form.The two ends of winding are connected with can be with two windings in series or change over switch K in parallel ₁As change over switch K ₁Moving some D, D ' with dead point A, when A ' is communicated with, two windings connect mutually also.As change over switch K ₁Moving some D, D ' with dead point C, when C ' is connected, two windings are connected in series mutually.By the series and parallel of two windings, can change transformer-secondary voltage and electric current, make this transformer when starting, can provide big electric current, and when charging, can reduce no-load current, save electric energy.Secondary winding of transformer is to be made of the startup winding of mutual serial connection, segmentation winding.Wherein start winding L 2-1 one end and be connected with bridge rectifier one input, the other end is through change over switch K ₂Be connected with another input of bridge rectifier, constitute start-up circuit.By starting winding L _2-1With with its segmentation winding L that is connected in series mutually _2-2--L _2-6Constitute the charging winding.Start winding L _2-1An end be connected with bridge rectifier one input, with the segmentation winding L _2-2To L _2-6The charging that is connected of tap regulate change over switch K ₃Warp and its ammeter that is connected in series mutually, fuse, circuit changing switch K ₂Be connected with another input of bridge rectifier, constitute charging circuit.By changing circuit changing switch K ₂, can realize the conversion of start-up circuit and charging circuit, and change over switch K is regulated in charging ₃Can change the output voltage of charging circuit.

Claims

1, a kind of motor vehicle starting charge dual-purpose machine, comprise transformer, charging circuit and start-up circuit, it is characterized in that the primary winding be by two can be connected in series mutually or and the winding that connects constitute, be connected with change over switch between two windings, realize string and connect by change over switch.
