The utility model discloses an indicator for automobile door close, which comprises a lucky speech signal generator and an alarm signal generator, wherein, the lucky speech signal generator which is connected with the live conductor controlled by an ignition switch is formed into a trigger type speech integrated piece; the power of the alarm signal generator is supplied by power supply, and the alarm signal generator is connected with a circuit which is controlled by an automobile door switch. When the automobile door is opened, the utility model can send out alarm signal. The indicator for automobile door close is used for avoiding the accidents caused by not closing automobile doors tightly when the automobiles are driven in high speed or turns particularly. The utility model has the advantages of simple structure, good beautility, and reliable performance.
Description
The utility model relates to a kind of automobile device for closing door alarming, specifically is exactly a kind of automobile warning device of closing the door.
Automobile when running at high speed, if car door do not close tight, then very dangerous.Vehicle door status speech demonstration on the minority automobile utilizes vehicle microcomputer control, and it involves great expense, and most vehicles are not equipped with.
Task of the present utility model is to provide a kind of automobile device for closing door alarming that multiple vehicle is used that is suitable for, and it can send the language alarm signal when arrangements for automotive doors is not fastened, remedied the deficiency of prior art.
Task of the present utility model is to realize like this.It is a self contained system, establishes two speech signal producers in this device, and one of them speech signal producer is connected automobile and is subjected to be the triggering form on the live wire circuit of ignition lock control; Another one speech signal producer is powered by automobile power source, is connected on automobile door switch's circuit, and the audio pulse that two speech signal producers send is delivered to loud speaker through filtering and amplification and sent the language alarm signal.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a functional block diagram of the present utility model.
Fig. 2 is schematic circuit diagram of the present utility model.
As shown in Figure 1, speech signal producer 1 is connected on the live wire circuit that is subjected to ignition lock control, and it is that a kind of language set is in blocks, be trigger-type, car engine once, it triggers once, audio pulse is delivered to filter circuit, be amplified to loud speaker through amplifying circuit and send the lucky signal of wishing; Speech signal producer 2 is that a language set is in blocks, by the automobile power source power supply, and controller control, it through filter circuit and amplifying circuit, is delivered to alerting signal loud speaker and sends the language alarm signal.
As shown in Figure 2, speech signal producer 1 is that IC1 selects for use the HD5603 language set in blocks, it is connected on the live wire circuit that is subjected to ignition lock control, R1, R3, C2 is its peripheral cell, the control intonation, once energized, just obtain triggering once, export lucky language impulse singla, deliver to C3, C4, R4, filter circuit and IC3 power amplifier that R5 constitutes, the IC3 model is LM386, send the lucky signal of wishing by loud speaker at last, " have a good trip " etc. as " may you be hapy and prosperous ", speech signal producer 2 is that IC2 selects HFC5200 for use, by the automobile power source power supply, is attempted by on the door contact interrupter circuit, K is a push type automobile door switch, as shown in the figure be the automobile door closing state, R1, C1 is its peripheral cell, and the control intonation also provides the time-delay of certain hour, this language set trigger end in blocks and positive source join, grounding leg 4 is controlled by door contact interrupter K, and as car door opening, K connects, then communicate with power cathode, constitute the loop, IC2 then has the language impulse singla to send, through filtering and IC3 amplifying circuit, send the language alarm signal through loud speaker, as " please close the door " etc.If during closing of the door, then K is in open position, and the IC2 pulse-free signal sends, i.e. the alarm free signal.
The a termination is subjected to the live wire of ignition lock control, b termination automobile negative pole.
Stabilivolt DW provides 3V operating voltage to IC1 and IC2.
It is the robot shape that the utility model can be made outward appearance, places in the operator's compartment, is aided with time display apparatus and secondary light source again, and multi-functional machine is driver and conductor's desirable articles for use.
It is specially adapted to miniature car and uses, and does not fasten to throw away because of car door in the time of can preventing automobile start or emergency brake to cause the accident, and it is handsome in appearance, and cost is low, reports to the police accurately, is easy to promote.
