Abstract

The utility model provides a vehicle warning device, and the integration of the vehicle warning device is composed of a radio transmitting part and a receiving part. Under a normal condition, an alarm is in a stand-by state, and the receiving part works and the transmitting part is out of service. When the vehicle has to be stopped because of failure, the alarm is actively triggered by a driver. Or when an impact accident happens, vibration can be brought on and thus a converting switch is triggered to be converted. Thus the transmitting part works to send out electromagnetic waves which are received by other alarms in an effective acting distance to alarm. Thus the driver is reminded decelerating so that a rear collision accident which is caused by that viewing distance is influenced by heavy fog can be avoided. The utility model is mainly suitable for vehicles which are running on a highway on a foggy weather.

Description

The automobile alarming device

The utility model belongs to the electronic alarm technique field.

For fogday traffic safety, existing method is that the automobile tail light of emission yellow visible light are installed at the tailstock, but this kind method obvious ranging coverage in mist is too small, for vehicle at running on expressway, it is too late that chaufeur often reacts, and causes rear-end collision, even many automobiles hit together.And because the rectilinear propagation mode of light, its sphere of action also only limits to first car thereafter, owing to block, later again vehicle just can't have been seen.

The purpose of this utility model provides a kind of automobile alarming device, and when car was collided, its can actv. send signal, warns other vehicle drivers and notes, so that take brake measure in advance, thereby avoids or alleviates vehicle damage and personal casualty.

The purpose of this utility model is realized by following technical scheme: this design is decay and the popularity of propagating in air according to electromagnetic wave, that is: under the little situation of power, because the decay that air causes, electromagnetic wave propagation distance is limited, and extensively distributes in this scope.If there is accident to take place, annunciator triggers by vibrations, and emission small power electric magnetic wave is by annunciator on all vehicles in its ranging coverage is received and amplifies and warn.This alarming device is the emission that is made of power supply, vibrations triggering change-over swith, radio transmission part, radio reception partial sum amplifier section--receive all-in-one.Vibrations trigger change-over swith and comprise vibrations binary pair and relay.Relay plays the double pole double throw effect, and the p point connects antenna, q point power connection positive potential, and acceptor circuit meets normally closed contact a, b, and transmission circuit meets open contact c, d.Vibrations binary pair system supports a hollow metal sleeve and a spring by insulating support.Spring is positioned at the metal cylinder axis, and there is a derby at the middle part, spring--derby--, and spring is good conducting, and through the metal cylinder axis.Metal socket joint high potential.Spring 1 end m point connects the relay excitation circuit, and other end n point is by a resistance eutral grounding.Relay f point ground connection.Circuit card and insulating support by screw retention on base plate.Radiating portion is by low-frequency oscillatory network, and--audio oscillator circuit--special-purpose transmitter module--antenna constitutes, and antenna is the built-in aerial close with casing length, also can install external antenna additional.Receiving unit adopts the receiver module that is complementary with transmitter module.Amplifier section is made up of amplification module and loud speaker.

The utility model is compared with background technology, and the beneficial effect that is had is:

1. ranging coverage is far away, and scope is wide, can be suitably apart from interior all car alarmings near accident site.

2. can effectively reduce express highway traffic accident incidence between mist.

3. even get into an accident, also can avoid the expansion of traffic accident, prevent many automobiles and hit one

The serious consequence that rises.

The utility model description of drawings is as follows:

Accompanying drawing 1 is the circuit diagram that the utility model adopted.

Accompanying drawing 2 triggers the change-over switch arrangement scheme drawing for the utility model vibrations.

Accompanying drawing 3 is the utility model inner structure vertical view cutaway drawing.

Accompanying drawing 4 is the utility model inner structure elevational cross-sectional view.

The utility model embodiment is as follows: by power supply, vibrations trigger change-over swith, radio transmission part,

The emission that radio reception partial sum amplifier section constitutes--receive all-in-one.Power supply 5 adopts 6V or 9V layer-built battery.Vibrations trigger change-over swith and comprise vibrations binary pair and relay.Relay plays the double pole double throw effect, and the p point connects antenna, q point power connection positive potential, and acceptor circuit meets normally closed contact a, b,

Transmission circuit meets open contact c, d.Vibrations binary pair system supports a hollow metal sleeve 3 and spring 2 by insulating support 4.Spring 2 is positioned at metal cylinder 3 axis, and there is a derby 1 at the middle part, and spring--derby--spring is good conducting, and through metal cylinder 3 axis.Metal cylinder 3 connects high potential.Spring 2 one end m points connect the relay excitation circuit, and other end n point is by a resistance eutral grounding.Relay f point ground connection.Circuit card and insulating support 4 by screw retention on base plate.Radiating portion is by low-frequency oscillatory network, and--audio oscillator circuit--special-purpose transmitter module--antenna constitutes, and antenna is the built-in aerial close with casing length, also can install external antenna additional.Receiving unit adopts the receiver module that is complementary with transmitter module.Amplifier section is made up of amplification module and loud speaker 6.Under the normal circumstances, annunciator is in readiness for action, and promptly power supply 5 and antenna are supported receiving unit, receiving unit work, and radiating portion is not worked.Shake in the relay excitation circuit that triggers change-over swith 7 or door zero setting, relay is in a, b point attracting state.If automobile clashes into, annunciator is subjected to enormous impact, because inertia, derby 1 overcomes the pulling force of spring 2 and the metal cylinder 3 formation current path that contacts, and m point current potential raises, or the door upset, the output high level also keeps, energizing circuit is connected, and the relay operating point becomes c, d point, and power supply 5 and antenna transfer the support transmission circuit to.Not gate F1, F2 produce oscillating signal, and the audio frequency oscillator through diode D1 control F3, F4 constitute makes it produce interrupted oscillating impulse, sends into CBF1 transmitter module modulated high frequency signal after F5, F6 shaping, is launched by antenna.Be in that another annunciator receiving unit in the sphere of action is received signal after demodulation, amplification, loud speaker 6 sounding alarms, or drive speech IC and report to the police.Roll sphere of action away from, then no longer report to the police.Circuit detecting method is: press switch k2, then radiating portion and receiving unit are worked simultaneously, and it is normal that loud speaker sends the sound explanation circuit of warning, and can judge power status by LED brightness simultaneously.
