The shift knob of defrost switch of the present utility model is set on bearing circle, is button form, can be also the form of stirring.As shown in Figures 2 and 3, the shift knob of this defrost switch is arranged on the turning support 2 of bearing circle bottom, by bolt 1, is fixed on turning support 2.
The signal wire (SW) of defrost switch will be connected with the air-conditioner controller on air conditioning for automobiles console, and because defrost switch is arranged on the turning support 2 of bearing circle, when rotating of steering wheel, this signal wire (SW) will rotate with bearing circle, and therefore, signal wire (SW) is flexible.In addition, for guard signal line, preferably this signal wire (SW) and clock spring are bundled, by clock spring, be connected with the air-conditioner controller on air conditioning for automobiles console.So, this signal wire (SW) equally can be with rotating of steering wheel, and can not affect other function of clock spring.
Fig. 4 has shown being connected of bearing circle and clock spring 4, and the joint of clock spring 4 is connected to the button of defrost switch through interface 3.Bearing circle and clock spring 4 are together fixed on turning support 2.Fig. 5 has shown wire harness connection diagram, and as shown in the figure, clock spring wire harness 4 is connected on dashboard cable harness 5, then is connected with the air-conditioner controller wire harness 6 on air conditioning for automobiles console by dashboard cable harness 5, and air-conditioner controller wire harness 6 is connected to air-conditioner controller.
Above-mentioned defrost switch can be front defrost switch, for controlling air-conditioning box air-out, is front defrosting mode.If air-conditioner controller is operated in the mode of operation beyond front defrosting, stir or press this front defrost switch, can be front defrosting mode by making air-conditioning box air-out.If the air-out mode of air-conditioner controller is front defrosting, and air-conditioner controller do not close, and stirs or press this front defrost switch, before switching defrosting mode to before air-out mode.
Above-mentioned defrost switch can be rear defrost switch, for controlling air-conditioning box air-out, is front defrosting mode.Correspondingly, if air-conditioner controller is operated in rear defrosting mode of operation in addition, stirring or press this rear defrost switch, can be rear defrosting mode by making air-conditioning box air-out.If the air-out mode of air-conditioner controller is rear defrosting, and air-conditioner controller do not close, and stirs or press this rear defrost switch, after switching defrosting mode to before air-out mode.
In addition, two defrost switches also can be set, one as front defrost switch, and one as rear defrost switch.
The utility model also provides a kind of defrost control system, and this system comprises the first front defrost switch being positioned on central vehicle control desk, and the second front defrost switch of foregoing switch, air-conditioner controller.
The first front defrost switch and the second front defrost switch are all connected to air-conditioner controller, all can open the front defrosting mode of operation of air-conditioner controller or close front defrosting mode of operation.Fig. 6 has shown the circuit theory that defrost control system is controlled, and air-conditioner controller for example can be realized by the S9S08LG32 chip of FREESCALE.Pattern damper motor is to realize the actuating unit that air-conditioning box switches air-out mode, by air-conditioner controller, pattern damper motor is set to different feedback voltages, and make it work in different patterns, be generally blow face, blow pin, mixed wind, demist, five patterns of front defrosting.Air-conditioner controller receives the signal input of described the first front defrost switch and the second front defrost switch, when having front defrost switch to have signal input.Air-conditioner controller reads motor current location feedback voltage, thus the position (being current air-out mode) of judgement present mode air door.If current in the position of front defrosting, motor is by attonity; If, in front defrosting position, air-conditioner controller does not read the feedback voltage of defrosting mode position, and drive pattern damper motor moves to the position of front defrosting.
As shown in Figure 7, this system comprises the first rear defrost switch being positioned on central vehicle control desk to another embodiment of defrost control system of the present utility model, and foregoing the second rear defrost switch being arranged on bearing circle, air-conditioner controller.The first rear defrost switch and the second rear defrost switch are all connected to air-conditioner controller, all can open the rear defrosting mode of operation of air-conditioner controller or close rear defrosting mode of operation.
Defrost control system also comprises rear window heating unit (not shown), and air-conditioner controller heats control relay by rear window and is connected to rear window heating unit.The first rear defrost switch and the second rear defrost switch can be used for opening or closing rear window heating unit.
Air-conditioner controller receives the signal input of described the first rear defrost switch and the second rear defrost switch, when the first or second rear defrost switch has signal input.The closed rear window heating of air-conditioner controller control relay, thereby rear window heating unit starts energising work, when described the first rear defrost switch and the second rear defrost switch are closed, air-conditioner controller disconnects rear window heating control relay, and rear window heating unit quits work.In Fig. 7, show that rear window heating control relay is Low level effective, certainly can also be chosen as high level effective.
Another embodiment of defrost control system of the present utility model is, scheme shown in Fig. 6 and Fig. 7 is merged, this defrost control system comprises: be positioned at the first front defrost switch and the first rear defrost switch on console, be positioned at the second front defrost switch and the second rear defrost switch on the turning support of bearing circle, and air-conditioner controller.Its specific works mode with reference to Fig. 6 and Fig. 7, describe identical, do not repeat them here.
Above-described embodiment is typical embodiment of the present utility model; but the utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
