Abstract
Interlock circuit is controlled the utility model discloses a kind of electric automobile air conditioner, it is characterized in that, interlock relay is connected with condensation fan relay, signal compressor relay and PTC D.C. contactors respectively by circuit, air-conditioning switch controller is connected with interlock relay, compressor is connected with signal compressor relay, heats switch and blower control is connected on PTC D.C. contactors.By arrangement above, the utility model low level signal different by giving can rationally control air-conditioning start and stop, condensation fan start and stop and PTC electric heating wind start and stop.Meanwhile, the security of air-conditioning can be greatly improved by adding interlocking structure, prevent refrigeration from starting simultaneously with heating.Whole control system is simple and practical only with three relays and a D.C. contactor, cost reduction.
Description
Technical field
The utility model is related to a kind of ac control circuit, specifically a kind of electric automobile air conditioner control interlock circuit.
Background technology
Electric automobile air conditioner control is different from orthodox car air conditioning control method, and it heats to be heated with PTC and completed.It is existing
Electric automobile air conditioner control circuit it is complicated, pursue novel and ignore essence, cause not only cost of manufacture raising, and excessively multiple
The probability that miscellaneous circuit goes wrong also becomes big therewith.
The content of the invention
The purpose of this utility model is to provide a kind of electric automobile air conditioner control interlock circuit.
To achieve these goals, the technical solution of the utility model is：Interlock relay by circuit respectively with condensation
Blower fan relay, signal compressor relay and the connection of PTC D.C. contactors, air-conditioning switch controller connect with interlock relay
Connect, compressor is connected with signal compressor relay, heat switch and blower control is connected on PTC D.C. contactors.
As preferred technical scheme, interlock relay of the present utility model is normally closed relay.
As preferred technical scheme, condensation fan relay of the present utility model is normally opened relay.
As preferred technical scheme, signal compressor relay of the present utility model is normally opened relay.
As preferred technical scheme, PTC D.C. contactors of the present utility model are normally opened D.C. contactor.
By arrangement above, the utility model low level signal different by giving can rationally control air-conditioning start and stop, cold
Solidifying blower fan start and stop and PTC electric heating wind start and stop.Meanwhile, the security of air-conditioning can be greatly improved by adding interlocking structure, prevent refrigeration
Start simultaneously with heating.Whole control system is simple and practical only with three relays and a D.C. contactor, cost drop
It is low.
Brief description of the drawings
The utility model is described further in conjunction with accompanying drawing.
Fig. 1 is circuit control principle figure of the present utility model.
In figure：1st, interlock relay, 2, condensation fan relay, 3, signal compressor relay, 4, the contact of PTC direct currents
Device, 5, air-conditioning switch controller, 6, compressor, 7, heat switch, 8, blower control, 9, condensation fan.
Embodiment
As shown in figure 1, interlock relay 1 of the present utility model by circuit respectively with condensation fan relay 2, compressor
Signal relay 3 and PTC D.C. contactors 4 are connected, and air-conditioning switch controller 5 is connected with interlock relay 1, compressor 6 and pressure
Contracting machine signal relay 3 is connected, and heats switch 7 and blower control 8 is connected on PTC D.C. contactors 4.It is described interlocking after
Electrical equipment 1 is normally closed relay.The condensation fan relay 2 is normally opened relay.The signal compressor relay 3 is normally opened
Relay.The PTC D.C. contactors 4 are normally opened D.C. contactor.
By arrangement above, condensation fan relay 2 of the present utility model is connected with condensation fan 9,
After electric automobile starts, blower control 8 opens air blower, then electricity 12V on air blower, then condensation fan after
Electrical equipment 2, signal compressor relay 3 and PTC D.C. contactors 4 also go up electricity 12V.Startup heats switch 7, then it is straight to touch PTC
The REL actions on the KM and interlock relay 1 on contactor 4 are flowed, the high-tension electricity of output acts on PTC D.C. contactors 4 and started
Heating.Its coil electricity can be made while pass to the REL on interlock relay 1 by heating the ground signalling of switch 7, then REL's touches
Point disconnects, accordingly even when air conditioner refrigerating switch is pressed, will not also make starting of air conditioner, reach protective effect.When heating, switch 7 is motionless
Make, when air-conditioning switch controller 5 works, because the REL on interlock relay 1 is normally closed relay, air-conditioning switch controller 5
Ground signalling can be transmitted to the REL on the REL on condensation fan relay 2 and signal compressor relay 3 simultaneously, make condensation fan
Relay 2 and signal compressor relay 3 are closed, and compressor 6 and condensation fan 9 work, and reach the purpose of refrigeration.
