Abstract
The utility model relates to a steering voice prompt circuit in a car cab, which solves the problem of lack of obvious voice prompt signals for a driver during the steering of the automobile. The utility model mainly adopts the following structure: a relay is arranged between steering signal input terminals and a power source negative terminal, the steering signal input terminals adopt a left steering signal input terminal and a right steering signal input terminal, one diode is connected in series between the left steering signal input terminal and the relay, another diode is connected in series between the right steering signal input terminal and the relay, the two diodes are connected to one end of the relay after being connected in parallel, and two ends of the relay are connected in parallel with a capacitor and a resistor. The design with the two diodes can prevent two signals from interfering with each other, and the capacitor and the resistor connected in parallel to the two ends of the relay can enable the sound production frequency to be more uniform.
Description
Technical field
The utility model relates to a kind of cue circuit, and more particularly, the utility model relates to a kind of automobile cab and turns to auditory tone cues electric circuit.
Background technology
Traditional automobile is when turning to, can only play schillerization, do not have chaufeur motor turning in the auditory tone cues compartment, have some now and chaufeur is carried out reminding turning by visual signal, as the reminding turning on the combination instrument, but visual signal disperses the attention of driver's eyes easily, and such visual signal is often obvious inadequately, can't play the effect of prompting chaufeur.
Patent Office of the People's Republic of China discloses the CN2079135 document on December nineteen ninety 12, name is called the motor turning Der Blink und Abblendschalter, this apparatus structure is for being provided with relay between change-over swith and power supply, in the interior coil circuit in parallel of this relay with normally open contact, series diode and current-limiting resistance, and at the motor turning Der Blink und Abblendschalter of relay coil two ends parallel capacitance.This device is owing to adopt the normally open contact relay that continues more, when the normally open contact parallel connection, and when being used for a display lamp circuit, the standby contact when its multiple contact can be pitting of contacts, the service life of prolongation Der Blink und Abblendschalter.The parallel connection of contact input end, mouth connect display lamp respectively and connect fault alarm.Can satisfy and show and show the fault alarm effect.When motor turning, this device can not provide the aud. snl. of obvious prompting chaufeur.
Summary of the invention
The utility model does not have when having solved motor turning obviously to point out the problem of the aud. snl. of chaufeur, can provide the automobile cab of auditory tone cues to turn to auditory tone cues electric circuit when a kind of motor turning is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automobile cab turns to auditory tone cues electric circuit, between turn sign input end and the power supply negative terminal relay is set, described turn sign input end has two, be respectively left direction signal input end and right steering signal input part, series diode between left direction signal input end and the relay, series diode between right steering signal input part and the relay, receive an end of relay after described two diode parallel connections, the two ends parallel capacitance and the resistance of relay.Use the design of two diodes can prevent phase mutual interference between two signals, the two ends parallel capacitance of relay and resistance can make audible frequency more even.
As preferably, described relay is an electromagnetic type relay.
As preferably, the resistance of described resistance is 1.5K Ω-2.0K Ω, capacitance 4.7 μ F.
As preferably, the diode forward working current is smaller or equal to 1A, reverse withstand voltage 1000V.
The utility model beneficial effect is: relay on-off is sounded during motor turning, provides aud. snl. prompting chaufeur automobile to turn to, and makes chaufeur can obtain automobile just at diversion signal under the situation that the eyes attention is not disperseed.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model;
Among the figure: 1. relay, 2. resistance, 3. electric capacity, 4. left direction signal input end, 5. right steering signal input part, 6. diode.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of automobile cab turns to auditory tone cues electric circuit (referring to accompanying drawing 1), electromagnetic type relay 1 is set between turn sign input end and the power supply negative terminal, described turn sign input end has two, be respectively left direction signal input end 4 and right steering signal input part 5, series diode 6 between left direction signal input end 4 and the relay 1, series diode between right steering signal input part 5 and the relay 1, receive an end of electromagnetic type relay 1 after described two diode parallel connections, the electric capacity 3 of the two ends of electromagnetic type relay 1 4.7 μ F in parallel and the resistance 2 of 1.7K Ω.
Automobile is in the principle of work under each state:
1, left steering: open the left steering switch, this moment, the left steering lamp was intermittently glittering, and intermittently signal power source is charged to electric capacity 3 by diode 6 through left direction signal input end 4, treated that electric capacity 3 is full of the electricity back to relay 1 discharge, relay 1 contact adhesive; After treating that electric capacity 3 has been put electricity, relay 1 contact open is sounded.
2, right steering: open the right steering switch, this moment, the right steering lamp was intermittently glittering, and intermittently signal power source treats that through turning to relay right steering signal input part 5 and passing through diode 6 to electric capacity 3 chargings electric capacity 3 is full of the electricity back to relay 1 discharge, relay 1 contact adhesive; After treating that electric capacity 3 has been put electricity, relay 1 contact open is sounded.
3, alarm lamp: open the alarm lamp switch, this moment, left and right steering indicating light was intermittently glittering, intermittently signal power source left direction signal input end 4, right steering signal input part 5 to electric capacity 3 chargings, treat that electric capacity 3 is full of the electricity back to relay 1 discharge, relay 1 contact adhesive by diode 6; After electric capacity 3 had been put electricity, relay 1 contact open was sounded.
Increase by 1 mounting hole on relay 1, by mounting hole relay 1 is installed on combination instrument and the combined switch limit, turn to and alarm switch when opening, chaufeur can be seen indicator lamp, can hear sound simultaneously.
Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
