Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Embodiment one
A kind of synoptic diagram of the horn of motor vehicle that Fig. 1 provides for the embodiment of the invention one.
As shown in Figure 1, the horn of motor vehicle of present embodiment comprises pick-up unit and control device.Terminal 1 connects the automobile power source positive pole among Fig. 1, terminal 2 connects the automobile steering wheel loudspeaker pushbutton switch, terminal 3 connects the automobile power source negative pole, and described horn switch button is pressed or break-make that down state does not come link (not shown) between control terminal 2 and the terminal 3 by oneself.
Wherein, pick-up unit comprises resistance 100, photodiode 102.Control device comprises resistance 104, phototriode 106.
When not pressing horn button, between terminal 1-resistance 100-photodiode 102-terminal 2, do not form effective closed-loop path, resistance 100 in the pick-up unit does not have electric current to pass through, there is not electric current to pass through in the photodiode 102 as optoelectronic switch yet, thereby can be not luminous, therefore the phototriode 106 in the control device obtains the suitable bias voltage that is used for conducting, namely between terminal 1-resistance 104-phototriode 106-terminal 3, can not form effective closed-loop path, thereby all do not have electric current to pass through in phototriode 106 and the resistance 104.And described phototriode 106 not conducting directly cause giving the grid of field effect transistor 108 that suitable bias voltage is provided, therefore field effect transistor 108 can conducting, thereby between terminal 1-loudspeaker unit 110-field effect transistor 108-terminal 3, can not form effective closed-loop path, cause not having electric current to pass through in the loudspeaker unit 110, loudspeaker unit 110 can not produce and pipe.
When horn switch button is pressed, form effective closed-loop path between the terminal 1-resistance 100-photodiode 102-terminal 2, all there is electric current to pass through in resistance 100 and the photodiode 102, photodiode 102 is luminous through resistance 100 current limlitings, phototriode 106 conducting after receiving the light signal that photodiode 102 sends, thereby for field effect transistor 108 grids provide a positive bias, field effect transistor 108 conductings, thereby between terminal 1-loudspeaker unit 110-field effect transistor 108-terminal 3, form effective closed-loop path, there is electric current to pass through in the loudspeaker unit 110, pipes thereby send.
Being noted that described loudspeaker unit 110 can be the standard machinery loudspeaker, also can be electronic horn.
The effect that is noted that in addition the electric capacity in parallel with pick-up unit 112 is to carrying out bypass at horn button to the noise pulse that produces owing to the wire harness induction between the loudspeaker unit 110, preventing that photodiode 102 is subjected to described noise pulse to disturb mistake luminous.The electric capacity 114 that is connected between phototriode 106 and field effect transistor 108 and the electric capacity 112 in parallel with field effect transistor 108 also play similar bypass effect to prevent that field effect transistor is disturbed by noise pulse and misleaded, the effect of resistance 116 is to consist of the dc partial voltage biasing circuit with resistance 104, for field effect transistor 108 grids provide suitable bias voltage.
It is worth mentioning that, if described loudspeaker unit 110 is electronic horns.Can also introduce so the audible warning generation unit to be provided for amplifying the audible warning of control for described loudspeaker unit.Below by embodiment two this horn of motor vehicle is elaborated.
