The utility model relates to a correlation circuit structure of an engine and an air condition compressor. The correlation circuit structure comprises a positive electrode power supply, an air condition rocker switch, an engine EUC, an engine EUC relay, an air condition relay and the air condition compressor. The positive electrode power supply is connected with the air condition rocker switch, the air condition relay and the engine EUC relay. The air condition rocker switch is connected with a port 1 of the engine EUC. A port 2 and a port 3 of the engine EUC are connected with a control loop of the engine EUC relay and control closing and opening of the engine EUC relay which is connected in series to a control loop of the air condition relay to control turning on and off of the air condition relay. The air condition relay is connected with the air condition compressor. By controlling the air condition rocker switch, the engine controls the engine EUC relay, the engine EUC relay is connected in series to the control loop of the air condition relay, the engine EUC relay controls the air condition relay, and accordingly air condition compressor working is controlled.
Description
Technical field
The utility model relates to the interlock circuit that air condition compressor starts, particularly about the associated circuit structure of a kind of motor and air condition compressor
Background technique
Automobile air conditioner compressor starts needs larger input power, these power all need to obtain from motor, and the Main Function of motor is to provide power for automobile running, so just require air condition compressor motor when starting must make the response that improves output power, thereby produce the associated circuit demand of motor and air condition compressor.
Model utility content
The purpose of this utility model is, a kind of circuit design is provided, and sort circuit can be realized after Engine ECU (Electronic Control Unit) receives starting of air conditioner signal and improve engine output, and controls air condition compressor and start.
To achieve these goals, the utility model adopts following technological scheme.
The associated circuit structure of motor described in the utility model and air condition compressor comprises a cathode power supply, an air-conditioning rocker switch, an Engine ECU, an Engine ECU relay, an Air Conditioner Relay, an air condition compressor.
Wherein, cathode power supply connects air-conditioning rocker switch, Air Conditioner Relay, Engine ECU relay,
The port one of air-conditioning rocker switch connecting engine ECU, the port one of Engine ECU is air-conditioning request port,
Port 2, the 3 connecting engine ECU relays of Engine ECU,
Engine ECU relay connects Air Conditioner Relay,
Air Conditioner Relay connects air condition compressor.
Port 2, the 3 connecting engine ECU relays of Engine ECU, form Engine ECU relay control circuit;
Cathode power supply connecting engine ECU relay, Engine ECU relay connects Air Conditioner Relay, forms Engine ECU relay main power circuit;
Engine ECU relay connects Air Conditioner Relay, forms Air Conditioner Relay control loop;
Cathode power supply connects Air Conditioner Relay, and Air Conditioner Relay connects air condition compressor, forms Air Conditioner Relay main power circuit.
Working principle of the present utility model is: because cathode power supply connects air-conditioning rocker switch, the port one of air-conditioning rocker switch connecting engine ECU, the control loop of air-conditioning rocker switch control engine ECU relay;
The main power circuit of Engine ECU relay control circuit control engine ECU relay;
Engine ECU relay main power circuit is controlled the control loop of Air Conditioner Relay;
Air Conditioner Relay control loop is controlled the main power circuit of Air Conditioner Relay.
When air-conditioning rocker switch is closed, Engine ECU is received starting of air conditioner signal boost engine output from port one, and control engine ECU relay closes, because Engine ECU relay is connected in the control loop of Air Conditioner Relay, Air Conditioner Relay is closed, the air condition compressor normal operation being connected with Air Conditioner Relay.So just realize Engine ECU and first promoted engine output, then controlled the object that air condition compressor starts.
When air-conditioning rocker switch disconnects, Engine ECU receives that from port one air-conditioning stop signal control engine ECU relay disconnects, and reduction engine output, because Engine ECU relay is connected in the control loop of Air Conditioner Relay, Air Conditioner Relay disconnects, and the air condition compressor being connected with Air Conditioner Relay quits work.So just realize Engine ECU and first controlled air condition compressor and stop, then having reduced the object of engine output.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the circuit design of engine control air condition compressor startup
Reference numeral explanation:
1. Air Conditioner Relay
2. air condition compressor
3. Engine ECU relay
4. Engine ECU
5. air-conditioning rocker switch
6. cathode power supply
Embodiment
For the ease of persons skilled in the art, understand and realize the utility model, now describing by reference to the accompanying drawings a specific embodiment of the associated circuit structure of motor described in the utility model and air condition compressor.
As shown in Figure 1, the circuit design that engine control air condition compressor described in the utility model starts comprises a cathode power supply 6, an air-conditioning rocker switch 5, an Engine ECU 4, an Engine ECU relay 3, an Air Conditioner Relay 1, an air condition compressor 2.
Wherein, cathode power supply 6 connects air-conditioning rocker switch 5, Air Conditioner Relay 1, Engine ECU relay 3,
The port one of air-conditioning rocker switch 5 connecting engine ECU4,
Port 2, the 3 connecting engine ECU relays 3 of Engine ECU 4,
Engine ECU relay 3 connects Air Conditioner Relay 1,
Air Conditioner Relay 1 connects air condition compressor 2.
Port 2, the 3 connecting engine ECU relays 3 of Engine ECU 4, form the control loop of Engine ECU relay, can control engine ECU relay 3 closures, disconnection;
Cathode power supply 6 connecting engine ECU relays 3, Engine ECU relay 3 connects Air Conditioner Relay 1, forms the main power circuit of Engine ECU relay 3;
Engine ECU relay 3 connects Air Conditioner Relay 1, forms the control loop of Air Conditioner Relay 1, can control Air Conditioner Relay 1 closure, disconnection;
Cathode power supply 6 connects Air Conditioner Relay 1, and Air Conditioner Relay 1 connects air condition compressor 2, forms the main power circuit of Air Conditioner Relay 1.
When air-conditioning rocker switch 5 is closed, Engine ECU control engine ECU relay closes, because Engine ECU relay is connected in the control loop of Air Conditioner Relay, Air Conditioner Relay is closed, the air condition compressor normal operation being connected with Air Conditioner Relay.So just realize Engine ECU and controlled the object that air condition compressor starts.
When air-conditioning rocker switch 5 disconnects, Engine ECU control engine ECU relay disconnects, and because Engine ECU relay is connected in the control loop of Air Conditioner Relay, Air Conditioner Relay disconnects, and the air condition compressor being connected with Air Conditioner Relay quits work.So just realize Engine ECU and controlled the object that air condition compressor stops.
Although described the utility model by embodiment, but those of ordinary skills know, in the situation that not departing from spirit of the present utility model and essence, just can make the utility model have many variations and distortion, scope of the present utility model is limited to the appended claims.
