Abstract
The utility model relates to a monitor alarm for vehicle steering and braking light state, and the utility model is a device for monitoring the fault position of a vehicle light state. The circuit of the utility model is a composite monitoring alarm composed of a light testing circuit, a sound alarm prompting circuit and an accessory electronic flash circuit. The utility model is characterized in that the utility model can be used by changing a connecting and inserting thrum circuit under the condition of the prime vehicle circuit with no change. When a driver drives a vehicle, fault positions of steering light and braking light can be accurately reflected, and the safety of driving a vehicle can be effectively enhanced by six discoloring indication lamps and alarming sound. The utility model has the advantages of small size, good stability, convenient and simple installation, etc.
Description
The utility model relates to the integration unit of a kind of auto electronic circuit and components and parts technology.Particularly a kind of annunciator of monitoring vehicle lamp condition position of fault.
The quality of Vehicular turn, braking pilot light system, with traffic safety direct contact is arranged, in the vehicle ', if when turning to, braking light and breaking down, chaufeur can't be found and the traffic accident that causes happens occasionally, for fear of the generation of this class accident, chaufeur thirst for having a kind of can be at the annunciator of operator's compartment monitor lamp condition.
At present, the most vehicles in home and abroad lack turn to, the brake lamp condition monitor and alarm unit, be single and have similar steering indicating light condition annunciator, brake lamp condition annunciator, electronic flasher etc. now, exist many single functional devices and all be installed on operator's compartment, circuit connects messy, expense strengthens, and uses defectives such as inconvenience.
The purpose of this utility model is to overcome above-mentioned existing deficiency, provide a kind of by turning to, the brake lamp condition testing circuit, the variable color display circuit, the audible alarm cue circuit, set up the small-sized annunciator of multifunctional composite that the electronic flasher circuit is formed, it is characterized in that described light testing circuit and variable color display circuit are the resistance unit R11 that is monitored lighting circuit by being parallel to, R12, R13, R21, R22, R23, R51, R52, R53, by silicon diode VD21, VD22, VD31, VD32, VD41, VD42, VD51, VD52, VD61, VD62, form IC1 by two digital integrated circuits, IC2 constitutes; Form the variable color display circuit by LED1, LED2, LED3, LED4, LED5, LED6; The audible alarm cue circuit is made up of transistor V71, V72, V73 and resistor R 71, R72, R73 capacitor C 71 and loud speaker YD; Electronic flasher is made up of by pliotron V81 a slice 555 time-base integrated circuit IC3 and resistor R 81, R82, R83 and electrolytic condenser C81.Its energy direct mount appropriate location in facia board is not changing original turn signal swich, and under the situation of stop lamp switch, only conversion patches the end of a thread circuit and gets final product place in operation.Chaufeur comes by six variable color indicator lamps of plate face under steam, shows each position, the lamp condition just often presents green the demonstration, if when wherein arbitrary monitor lamp breaks down, the variable color indicator lamp will become red display in the corresponding instrument carrier panel, and send chimes of doom, inform that this position breaks down.
The utility model has been set up a kind of electronic flasher circuit, purpose is to set up for old-fashioned vehicle the usefulness of bad car danger warning, it is characterized in that mechanical type (being double-metal sheet type) Der Blink und Abblendschalter or semiconductor discrete component electronic type Der Blink und Abblendschalter than existing vehicle, it is strong to have load-carrying capacity, stable performance, long service life, the characteristics that fault is few, and have light, sound, the dual alerting signal of frequency conversion, be used for the bad car danger warning of fault function.
The drawing explanation of accompanying drawing
The light testing circuit is by resistance unit, is parallel to the buffer circuit that is monitored lighting circuit and silicon diode composition, forms by two digital integrated circuits; The audible alarm cue circuit that variable color display circuit and transistor discrete component are formed; The electronic flash circuit of setting up is made up of by pliotron a slice 555 time base circuits.
Accompanying drawing 1 Vehicular turn, brake lamp condition monitoring alarmer electrical schematic diagram are described in further detail the utility model below with reference to accompanying drawing:
The utility model principle of work: turn to usually, stop lamp switch KA2, KA3 be in off-state, resistance R 11, lamp HL1, ignition lock KA1 and storage battery form power circuit because the R11 resistance is very big, electric current by HL1 is very faint, so the HL1 lamp does not work.Because lamp HL1 filament resistance limit is little, make not circuit IC1 (13) pin be low level, (12) pin is high level, and (10) pin is low level, and variable color LED 1 sends green.The V71 aerotron b utmost point is also located high potential and is ended, and the audible alarm circuit of being made up of V72, R72, R73, C71 and YD is not worked and be noiseless.When lamp HL1 disconnected, positive voltage was added to IC1 (13) pin by R11, made (12) pin low level, and (10) pin is high level, and LED1 becomes red light by green light, V71b utmost point place's active potential and conducting, and the audible alarm circuit gets electric work, sends continuous alarm sound.
The same HL1 of lamp HL2--HL6 principle.
Glancing impact, gang switch KA3 connects LED5 and LED6 also becomes red light by green light, sends continuous alarm sound simultaneously, and its principle is the same.
When turning to, pole changer KA2 connects, form electronic flasher by V81 of time base circuit IC3 etc. and get electric work, make steering indicating light HL1, HL2 (or HL3, HL4) flash of light work, variable color LED 1, LED2 (or LED3, LED4) green light and red light are alternately glittering, sounding alarm sends the interruption chimes of doom synchronously, and principle is the same.
Diode VD11-VD61, VD12 one VD62 are isolation diode, make four steering indicating lights, and two brake lamies are independent separately, be independent of each other, as long as wherein arbitrary lamp has fault, all can send light, acoustic alarm, could remove the work of warning recovery normal monitoring after only remaining to have been got rid of fault.
It is little to the utlity model has volume, easy to use, is convenient to implement, and expense is cheap, can improve safety in the driving effectively, avoids because of Vehicular turn, the train operation accident of braking lighting fault by causing.
