Can motor vehicle install corresponding failure safety alarm, but existing safety alarm there is：The excessively complicated installation of system
Therefore how inconvenient and expensive the problem of can not popularizing produces a kind of simple and reliable, easy for installation fast
Prompt, power consumption is low and low-cost automobile safety alarm is people's problem anxious to be resolved.
Invention content
The present invention provides a kind of automobile safety alarm, which can solve the existing system of existing safety alarm
The excessively complicated installation inconvenience of system and expensive the problem of can not popularizing.
To solve the above-mentioned problems, the technical solution adopted in the present invention is：This automobile safety alarm, including meter
When integrated chip and alarm unit；The external power supply end of the timing integrated chip is connected by dropping resistor with positive pole
It connects, the ground terminal of the timing integrated chip is connected with power cathode；Between the dropping resistor and the power cathode according to
It is secondary to be serially connected with charging resistor, charge/discharge resistance and charge/discharge capacitance；The input terminal of the timing integrated chip is connected to described
Between charge/discharge resistance and the charge/discharge capacitance；The alarm unit, which has, to be detected and transmits the more of vehicle trouble signal
A detection switch；The output end of the timing integrated chip is connected by the alarm unit with the power cathode.
In above-mentioned technical proposal, more specific technical solution can also be：The timing integrated chip further includes having reset
End and discharge end；The reset terminal is connected with the external power supply end；The discharge end is connected to the charging resistor and institute
It states between charge/discharge resistance.
Further：The alarm unit includes multiple alarm branches of parallel connection, one in these described alarm branches
By neutral switch, parking gear switch and its detection switch, it alarm lamp it is in series；Remaining the every alarm
Branch is in series by the respective detection switch and the respective alarm lamp.
Further：The timing integrated chip is 555 timing integrated chips.
Further：The detection switch is microswitch or tongue tube.
Further：It is connected with buzzer between the alarm lamp and the power cathode.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1, since this alarm includes timing integrated chip and alarm unit, the external power supply end of timing integrated chip passes through decompression
Resistance is connected with positive pole, and the ground terminal of timing integrated chip is connected with power cathode, dropping resistor and power cathode
Between be sequentially connected in series charging resistor, charge/discharge resistance and charge/discharge capacitance, the input terminal of timing integrated chip be connected to fill/
Between discharge resistance and charge/discharge capacitance, alarm unit has multiple detection switch of monitoring motor vehicle safety signal, timing collection
It is connected with power cathode by alarm unit at the output end of chip, in this way, detection switch is respectively correspondingly arranged in motor vehicle
Parking brake at, the junction of trailer and front truck, trailer back door, at side door and at the elevating ram of trailer, motor vehicle is travelling
Or in operation process, these detection switch can timely and reliably transmit fault-signal control alarm unit alarm respectively, not only simple
List is reliable, quick and easy for installation, power consumption is low and of low cost；
2, since timing integrated chip further includes having reset terminal and discharge end, reset terminal is connected with external power supply end, discharge end
It is connected between charging resistor and charge/discharge resistance, in this way, after powering on, dropping resistor is by the operating current of whole device
It is limited in extremely low level, and by charging resistor and charge/discharge resistance to capacitor charging, charging voltage is less than predetermined voltage at this time
Value, the high electricity of timing integrated chip output, when charging voltage reaches scheduled voltage, timing integrated chip exports low level, this
When, capacitance is discharged over the ground by charge and discharge resistance, and when discharge voltage drops to scheduled voltage, the output of timing integrated chip is high
Level, and charging resistor is begun through with charge/discharge resistance to capacitor charging, so in cycles, to be obtained in output end
The oscillating impulse waveform of consecutive variations, audio driven is provided for alarm buzzer；
3, since alarm unit includes multiple alarm branches in parallel, one in these alarm branches is by neutral switch, parking
Gear switch and it detection switch, it alarm lamp it is in series, remaining every alarm branch is by respective detection switch
It is in series with respective alarm lamp, not only to gear and it can be also easy to produce the position of failure respectively and alarm respectively, and conducive to knowing
The other source of trouble；
4, since timing integrated chip is 555 timing integrated chips, under the premise of meeting alert if, power consumption is low and at low cost
It is honest and clean；
5, since detection switch is microswitch or tongue tube, meet alarm detection condition under the premise of, power consumption is low and cost
It is cheap；
6, due to being connected with buzzer between alarm lamp and power cathode, warning function can be reinforced.
