Abstract

The utility model relates to a voltage monitor for motor vehicles. The voltage monitor is a transistor switch circuit and is composed of the electronic components of transistors, resistors, etc. The voltage monitor implements monitoring to the output voltage of an accumulator and a generator, and is capable of reflecting the fault of the accumulator, the generator, a regulator and a circuit. A plurality of voltage values of the monitored results are respectively indicated by three light emitting diodes with different color in a combined luminous mode. The utility model has the advantages of stable operation, small volume, convenient installation, low cost, etc.

Description

Voltage moniter for motor vehicle
The utility model relates to a kind of motor vehicle voltage monitor, the accumulator on especially can the directly monitoring motor vehicle and the output voltage of generator.The instrument that also can implement to monitor for the working condition of the performance of accumulator, charging regulator.
Whether the operating voltage on the motor vehicle meets the requirement of rated voltage, is the basic assurance that can motor vehicle normally move.And whether depend primarily on be operated in the normal operating voltage serviceable life of accumulator.When voltage was on the low side, then output current also diminished, owing to there is not specified electric current input, supply voltage will produce bigger voltage drop with electric line.Continue to use, must damage accumulator.Can the generator on the motor vehicle export specified voltage, directly relates to the running and the accumulators electric energy supplement of engine.If generator output voltage is during less than ratings, engine can not run well, and the accumulators electric energy supplement is also still lost, and also can cause damaging the electricity consumption facility.At present, the output voltage of indication or reflection accumulator and generator on the motor vehicle, the performance of accumulator, the instrument of charging regulator working condition, instrument are found as yet.
The purpose of this utility model; A kind of output voltage at accumulator, generator on the motor vehicle is provided, and the performance of accumulator and the working condition of charging regulator etc. realize the display type instrument of directly monitoring.Utilize it can effectively avoid a series of faults that produce owing to under-voltage.
The purpose of this utility model is to realize like this; By 40 millimeters * 22 millimeters * 17 millimeters shell, display panel and place the voltage monitor that circuit board constituted in the shell.It places on the interior circuit board of shell, by three switching mode triodes, two silicon voltage regulator diodes, the light emitting diode of three different colours, eight resistance, electrode line is connected with the switch of motor vehicle, negative line ground connection bonding, and a voltage switch circuit that constitutes shows monitoring result with the illuminated in combination form respectively with the light emitting diode of three different colours.The utility model utilize transistorized switch performance, voltage stabilizing diode characteristic, realize dividing potential drop by resistor, methods such as control bias current realize that its monitoring result is errorless and achieve the goal.
Because adopt such scheme, monitoring project is more, show accurately, and only use 16 common electronic components in the circuit, have simple in structure, function admirable.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Among Fig. 1: 1. display panel.
2. screw fixed orifice.
3. shell.
4. show label.
5. printed-wiring board (PWB).
6. electronic component.
7. connection lead.
Among the figure: A1, A2, A3 are light emitting diode.
One. Fig. 2 explanation and battery tension monitoring:
Connect the switch of motor vehicle, can measure the magnitude of voltage of accumulator.When voltage smaller or equal to 10 volts, the BG1 conducting, A1 is luminous.During 11 volts of voltages, BG1.BG2 is conducting, and A1.A2 is simultaneously luminous.In the time of 12 volts, BG2 is in the dark saturated BG1 of making to be ended, and A2 is luminous.When voltage during more than or equal to 13 volts, BG3 is by also conducting of stable voltage of D2 input, and A2.A3 is simultaneously luminous again.Otherwise job order during voltage falling.Resistance R c is that a dividing potential drop sampling adjustable resistance is adjusted control by it, to guarantee the accurate of displayed value.
Two. the generator output voltage monitoring:
Pilot engine, by generator output voltage, with the above-mentioned course of work.A2, A3 is simultaneously luminous, and promptly provable generator output voltage is normal.If A3 is blink states, be generator discontinuous operation or loose contact.If A3 is not luminous, being generator does not have normal voltage output or does not generate electricity fully.
Three. the performance monitoring of accumulator:
Flame-out to the process of resetting that shuts down from generator, the magnitude of voltage when flame-out is compared with the magnitude of voltage behind the some hrs, can measure whether accumulator deposits electricity or car load has or not faults such as electric leakage.
Four. the monitoring of charging regulator working condition:
The voltage of accumulator is compared with the voltage of the accumulator of running behind the some hrs during starting.When voltage did not rise or descends, A3 was also luminous in operation process, can be determined as the charging regulator fault.
What the utility model also can be used for detecting motor circuit opens circuit, burns faults such as insurance.
