Abstract
The utility model discloses a night driving safety prompting device for automobiles, which is composed of a headlight circuit for automobiles, a time base circuit and a language integrated circuit. When headlights are turned on, the prompt for prompting the drivers to pay attention to the safety can be automatically carried out on time by clear and simple languages. The utility model has the advantages of compact structure and convenient installation and operation.
Description
The utility model relates to automotive safety warning device manufacturing technology field, specifically relates to a kind of safe alarm set of automobile night running.
The automobile night running, condition of road surface is clear not as daytime, and running time one is long, and the easy mental fatigue of driver unless you give your whole attention to it, can have traffic accident.
The purpose of this utility model can the clear language reminiscences of reminding the driver to drive with caution concisely when being to provide a kind of automobile night running.
The technical solution of the utility model is that a kind of automobile night running safety reminiscences is mainly become by Der Scheinwerfer mit FernlichtAbblendlichtStandlicht control circuit, time base circuit, the integrated circuit bank of language.The parallel connection of described time base circuit input end headlight power supply, described time base circuit mouth is connected with the trigger end of language integrated circuit.The mouth of language integrated circuit is by a transistor driving loudspeaker playback.
The utility model has the advantages that during night travel, when headlight one is opened, language reminiscences circuit is also connected, remind the driver to note night travel safety from employing clear clear and simple language by the time of setting, and compact conformation, easy to install.
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing 1 and embodiment.
The inventor selects the NE555 IC for use
1The multi-vibrator of forming EDM Generator of Adjustable Duty Ratio.At C
2Charge and discharge and seal in variable resistance RW in the circuit
1, RW
2, respectively as reminiscences open, fine setting between the stopping time.The power supply of reminiscences is through D

1The unidirectional protection filter circuit of forming.C
3Be time-base integrated circuit IC
1Filter capacitor.
When opening Der StandlichtScheinwerfer und Parkleuchtenschalter, also connected language reminiscences power supply simultaneously, positive supply passes through R
1, RW and D
2To C
2Charging, time-base integrated circuit IC
13 pin be in high level, trigger the language IC
2, drive the loudspeaker playback by brilliant collector T.Work as C
2Both end voltage rise to 2/3 o'clock of power line voltage, time-base integrated circuit IC
1Upset, IC
13 pin output low levels, the language circuit is closed, loudspeaker stop playback.While C
2Through D
3, R
2, RW
2Timely basic IC circuit
17 pin discharge over the ground, work as C
2Both end voltage drops to 1/3 o'clock of power line voltage, time base circuit IC
1Upset again, IC
13 pin export high level again, repeat said process.
