Abstract
The utility model belongs to the field of the automobile lighting product, particularly an alarm for the circuit breakage failure of an automobile signal lamp. The alarm for the circuit breakage failure of an automobile signal lamp is characterized in that the normally closed contact of a reed switch tube J1, a diode D1 and a buzzer SX are associated with the serially connected coil L1 and automobile signal lamp R1 after serially connected. The normally closed contact of a reed switch tube J1 and the common wire connection terminal of the coil L1 are connected with the control switch K1 of the lighting circuit. A tap a is led between the buzzer SX and the automobile signal lamp to be connected with an automobile battery. The alarm for the circuit breakage failure of an automobile signal lamp has the advantages of simple circuit construction, stable performance, the advantage that the alarm for the circuit breakage failure of an automobile signal lamp can alarm on time when the automobile signal lamp gets the fault, etc. The alarm for the circuit breakage failure of an automobile signal lamp is suitable for being installed in various automobiles without changing the power supply circuits of the automobile signal lamp.
Description
The utility model belongs to the automotive lighting product scope, specifically a kind of automobile signal light open circuit fault annunciator.
As everyone knows, China makes side-marker lamp, taillight, steering indicating light, the brake lamp that is applied to automobile at present, when automobile signal light breaks down, all can not auto alarm, cause the correctly motoring condition of display automobile, the other side's vehicles or pedestrians are caused misjudgment, and traffic accident takes place.
The purpose of this utility model just is to avoid above-mentioned shortcoming, provides a kind of and can in time remind, driver's automobile signal light open circuit fault annunciator.
The utility model can reach by following measure: in parallel with the coil L1 that is cascaded, automobile signal light H1 after reed switch pipe normally closed contact J1, diode D1, the buzzer phone SX series connection, the common terminal of reed switch pipe normally closed contact J1 and coil L1 is connected on the master cock K1 of automotive lighting circuit, draws tap a between buzzer phone SX and the automobile signal light and is connected with automobile storage battery.
Coil L2 one end is connected with master cock K2, the other end is connected on two automobile signal light H1, the H2 that is in parallel, reed switch pipe normally closed contact J2 links to each other with the anode of diode D2, the other end of reed switch pipe normally closed contact J2 is connected on the master cock K2, and the negative electrode of diode D2 then is connected with buzzer phone SX.
Coil L1, L2 are wound on respectively on the body of reed switch pipe normally closed contact J1, J2, when automobile signal light H1, H2, H3 just often, closed master cock K1, K2 energized, generate an electromagnetic field when electric current flowing through coil L1, L2, because the effect of electromagnetic field makes reed switch pipe normally closed contact J1, J2 become off-state by closure state, thereby no current flows to buzzer phone SX, does not produce warning.If vehicle signal indicator lamp H1 opens circuit or bad contact and when causing resistance to increase, coil L1 does not produce or produces small electric magnetic field, thereby reed switch pipe normally closed contact J1 can not keep off-state, rely on the elastic closure of himself, this moment, electric current flowed to buzzer phone SX by master cock K1, reed switch pipe normally closed contact J1, diode D1, buzzer phone SX is produced report to the police, when automobile signal light H2, H3 produced fault, buzzer phone SX also sent alerting signal as a same reason.The effect of diode D1 is to prevent in master cock K2 closure and K1 when disconnecting that electric current flows to automobile signal light H1 through reed switch pipe normally closed contact J1, shows chaoticly and automobile signal light occurs, and diode D2 is identical with the action principle of D1.
Description of drawings: accompanying drawing is the utility model schematic circuit diagram, also is the schematic circuit diagram of a kind of embodiment.
Mark among the figure: master cock K1, K2, coil L1, L2, reed switch pipe normally closed contact J1, J2, automobile signal light H1, H2, H3, diode D1, D2, buzzer phone SX.
Embodiment: the may command of circuit shown in accompanying drawing two-way automobile signal light, the break-make of master cock K1 control left steering lamp, the break-make of K2 control taillight.Taillight H2, H3 are 12 volts/8 watts, and steering indicating light is 12 volts/20 watts, and reed switch pipe normally closed contact J1, J2 are the JAG-32 type, and diode D1, D2 are the 2CZ type, and buzzer phone SX is 12 volts, and corresponding coil L1, L2 should turn to 32 circles and 76 circles respectively.Be loaded in the shell after by circuit shown in the accompanying drawing the welding of each element, automobile signal light H1 wherein, H2, H3 is in housing exterior, be loaded on respectively on the relevant position of automobile, then in the enclosure with the resin glue cast, each element in the shell flowed or blow over and cover completely be fixed as one, prevent owing to jolting of automobile damaged element, after the master cock K1 closure of left steering lamp, if automobile signal light H1 energy normal operation, because filament cold resistance value is less, it is big to start rush current, make coil L1 connect bigger electromagnetic field of moment generation at master cock K1, thereby reed switch pipe normally closed contact J1 disconnects, start the permanent magnetic field that reed switch pipe normally closed contact J1 can rely on coil L1 to produce after finishing and remain off-state, buzzer phone SX is reactionless, if this moment, automobile signal light H1 produced fault, then, weakening of coil L1 electromagnetic field rely on the elastic reset closure of self owing to making reed switch pipe normally closed contact J1, electric current flows to buzzer phone SX through diode D1, give the alarm, unless in time get rid of the fault of automobile signal light H1, otherwise buzzer phone SX just reports to the police ceaselessly.The circuit working principle of monitoring automobile signal light H2, H3 fault repeats no more here with noted earlier identical.
Alarm for circuit breakage failure of automobile signal lamp provided by the utility model, prove through service testing, have that circuit structure is simple, stable performance, can in time implement the characteristics such as fault alarm, be suitable for various automobiles to install, and the supply line that need not change automobile signal light.
Claims (3)
1, a kind of automobile signal light open circuit fault annunciator, form by housing, reed switch pipe, coil, buzzer phone, automobile signal light, master cock etc., it is characterized in that: be in parallel after reed switch pipe normally closed contact J1, diode D1, the buzzer phone SX series connection with the coil L1 that is cascaded, automobile signal light H1.
