By the adoption of the structure, the power supply system has the advantages of meeting power demands of various vehicle-mounted devices, achieving inversion between a 220 V voltage and a 12 V voltage, and making full use of city power so as to supplement automobile power supplies.
Description
Technical field
The utility model relates to the power supply of automobile and mobile unit thereof, particularly electric power system in a kind of Automobile.
Background technology
Along with improving constantly that each field requires vehicle, automobile repacking is also universal all the more, and especially various specialized equipments can be installed additional with car in car in government.Such as police vehicle, can in car, install vehicle-mounted monitoring system, vehicle-mounted cluster radio station, Vehicular water dispenser, 220v battery socket etc. additional.
Be not consider equipment electrostatic current for vehicle refitting at present, vehicle causes storage battery power shortage to light a fire after not using for a long time; And because vehicle self-carrying battery capacity is limited, the equipment period of service of installing additional does not allow long; Vehicle, without automatic reversal variable power source, can not utilize civil power by actv..
For the problems referred to above, electric power system in a kind of novel Automobile is provided, in meeting various mobile unit electricity consumptions, it is the problem that prior art need to solve that actv. utilizes civil power to supplement automobile power source.
Utility model content
Technical problem to be solved in the utility model is, electric power system in a kind of Automobile is provided, and to reach in meeting various mobile unit electricity consumptions, actv. utilizes civil power to carry out supplementary object to automobile power source.
For achieving the above object, the technical solution of the utility model is, electric power system in a kind of Automobile, is characterized in that: described electric power system is connected by disconnecting relay with additional storage battery for starting storage battery, and additional storage battery directly connects 12V DC load by general supply relay; Additional storage battery connects 220V AC load by general supply relay access inverter.
The conducting in the time receiving vehicle activation signal of described disconnecting relay, starts storage battery and additional storage battery UNICOM, simultaneously power supply.
Between described 12V DC load and general supply relay, be provided with fuse box.
In described electric power system, be provided with the adhesive of controlling main supply switch control general supply relay.
Between described 220V AC load and inverter, be provided with earth leakage protective air switch.
Electric power system in a kind of Automobile, owing to adopting above-mentioned structure, the utility model has the advantage of: 1, meet various mobile unit electricity consumption demands; 2, realize the inversion between 220V and 12V, actv. utilizes civil power to supplement automobile power source.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structural representation of electric power system in a kind of Automobile of the utility model;
In Fig. 1,1, start storage battery; 2, additional storage battery; 3, disconnecting relay; 4, general supply relay; 5, inverter; 6,12V DC load; 7,220V AC load; 8, earth leakage protective air switch; 9, fuse box; 10, control main supply switch; 11, driving engine; 12, electrical generator.
The specific embodiment
As shown in Figure 1, the utility model is connected by disconnecting relay 3 with additional storage battery 2 for starting storage battery 1, and additional storage battery 2 directly connects 12V DC load 6 by general supply relay 4; Additional storage battery 2 accesses inverter 5 by general supply relay 4 and connects 220V AC load 7.
Disconnecting relay 3 conducting in the time receiving vehicle activation signal, starts storage battery 1 and additional storage battery 2 UNICOMs, simultaneously power supply.
Between 12V DC load 6 and general supply relay 4, be provided with fuse box 9.Between 220V AC load 7 and inverter 5, be provided with earth leakage protective air switch 8.In electric power system, be provided with control main supply switch 10 and control the adhesive of general supply relay 4.
Starting storage battery 1 is former automobile battery, thereby is mainly for starter motor power supply, driving engine 11 to be lighted a fire; When driving engine 11 rear engine 11 of lighting a fire drives electrical generator 12 for starting storage battery charging.In this simple and easy electric power system, connect in civil power situation, after each switch opens, can realize commercial power charged.Engine ignition, can realize former car generator charging after each switch opens.
Disconnecting relay 3, by automobile ignition signal control, is realized the break-make that starts storage battery 1 and additional storage battery 2.In the time that ignition lock is opened, the pressurization of relay coil two ends, in coil, will flow through certain electric current, thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring and inhale to iron core under the effect of electromagnetic attracting force, thereby the moving contact with moving armature and break back contact (open contact) adhesive, starts storage battery 1 and additional storage battery 2 UNICOMs thereby drive.Can carry out like this and start storage battery 1 and additional storage battery 2 and isolate, prevent from causing after single storage battery from overusing and cannot light a fire because of power shortage.
Control main supply switch 10 and open, make the interior movable contact electricity of general supply relay 4 and break back contact adhesive, 12v power supply and inverter 5 input ends have electricity.When there being ignition signal input, when disconnecting relay 3 adhesive, start storage battery 1 and 2 parallel connections of additional storage battery, be current consumer power supply jointly; When without ignition signal input, disconnecting relay 3 can not adhesive, uses separately additional storage battery 2 power supplys, now forbids to use for a long time consumer.
When inverter 5 input ends have 12V electricity, and while opening inverse switch, 12v power inverter is 220v, and 220v mouth has electricity; When inverter 5 external source access civil powers (or 220v generating), inverter 5 is 12v by 220v inversion automatically, can realize storage battery charging and 12v power supply.In the external civil power situation of this scheme, can use continuously consumer.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
