Abstract
The utility model is chiefly used for indication and alarm of the automotive insurance circuit fault. The utility model can automatically indicate the fault position by lamp light, and shows the fault happening by a sound. For overhauling the automotive insurance circuit fault, the utility model has the advantages of convenience, accuracy and quick speed, and moreover, has simple structure.
Description
The utility model relates to the electrical installation in the automobile, especially reports to the police relevant with the indicating fault of motor insurance circuit.
The China open CN2034926U of utility model patent discloses a kind of automobile circuit fault display system, and wherein the fault of insurance circuit shows it is by two light-emitting diodes, and current-limiting resistance and switch are finished.Its weak point is: when the insurance circuit et out of order is blowout or bad contact, it can not in time automatically send warning and indicate position of fault, and must could determine behind the cooresponding fault display switch of the insurance circuit of pressing et out of order whether it fault has taken place, this is very inconvenient to the automobilist, made switch in this fault display circuit in addition, it has not only increased the complexity on the apparatus structure, and increased the volume of instrument, be unfavorable for installation and the layout of instrument in car.
The purpose of this utility model provides a kind of fault to the motor insurance circuit can send warning fast automaticly, and can indicate its position and indicating alarm device simple in structure.
The purpose of this utility model is to realize like this, each insurance circuit in this device all is furnished with a failure indicating circuit and a fault recognition switch circuit accordingly, also be equipped with in this device in addition can with the alarm sound circuit of a plurality of fault recognition switch circuit adapteds, and be connected to the two ends of insurance circuit; The fault recognition switch circuit is made up of two triodes and two current-limiting resistances, one of them aerotron is the NPN aerotron, its base stage is connected on the hot end of insurance circuit by a current-limiting resistance, current collection is the mouth of circuit very, link with the alarm sound circuit input end, the emitter of another PNP aerotron of emitter and this circuit links, and the base stage of this PNP aerotron links to each other by the cold end of current-limiting resistance and insurance circuit, and current collection is ground terminal very.The utility model working process is as follows: when ensureing appears in insurance circuit, its both end voltage is inevitable to raise immediately, make the light-emitting diode of failure indicating circuit make luminous indication, make two aerotrons and the conducting of fault recognition switch circuit, mouth is active potential, control chimes of doom Chinese percussion instrument warning sounding.If insurance circuit is normal, then its both end voltage is very little, and light-emitting diode does not work, and the mouth of fault recognition switch circuit is high-impedance state, and the alarm sound circuit is sounding alarm not.
Compared with prior art the utlity model has and find that fault is timely fast, determine the advantage of fail address intuitive and convenient, in addition because the mechanicalness parts such as the switch that make in the circuit of the present utility model are few, its advantage simple in structure in addition, that be convenient to mounting arrangements.
Shown in the Figure of description is the circuit diagram of the utility model embodiment.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure: the alarm sound circuit (3) that each insurance circuit RD in the utility model or rd are furnished with a failure indicating circuit (1) and a fault recognition switch circuit (2) and can match with a plurality of switch circuits (2), indicating circuit (1) is made of R1 and D1 series connection, and and RD or rd parallel connection.Switch circuit (2) constitutes by PNP aerotron BG1 and NPN aerotron BG2 and with current-limiting resistance R4 and R5 that base stage links, the grounded collector of BG1, the current collection of BG2 is the mouth C of switch circuit (2) very, and they all are connected on the input end I of alarm sound circuit (3).The cold end a of insurance circuit RD or rd also is connected to a grounding resistance R6 in the present embodiment, and it breaks down RD or rd and current consumer when also opening circuit, and the utility model also can be finished the indication warning function.
Alarm sound can take place as long as have under the effect of active potential control signal in alarm sound in the utility model (3), in the embodiment shown in the figures, sound circuit (3) is by current-limiting resistance R2, biasing resistor R3, PNP aerotron BG3 squealer M, cond constitutes.
Automobile total power switch K in the accompanying drawing and each current consumer switch R can install in the utility model as required.
Claims (2)
1, a kind of boxlike motor insurance fault indicating alarm device that includes insurance circuit RD or rd is characterized in that: each insurance circuit RD or rd in this device are furnished with a failure indicating circuit (1) and a fault recognition switch circuit (2) accordingly; Also be equipped with alarm sound circuit (3) in addition in this device with a plurality of fault recognition switch circuits (2) adapted; Wherein failure indicating circuit (1) is in series also and insurance circuit by current-limiting resistance R1 and light-emitting diode D1, RD or rd parallel connection, fault recognition switch circuit (2) is made up of two aerotrons and two current-limiting resistances, one of them is NPN aerotron BG2, its base stage is joined by current-limiting resistance R5 and cooresponding insurance circuit hot end b, its current collection is the mouth C of this circuit (2) very, the emitter of another PNP aerotron BG1 of emitter and this circuit (2) links, the base stage of BG1 is joined grounded collector by the cold end a of current-limiting resistance R4 and cooresponding insurance circuit; The input end 1 of alarm sound circuit (3) links with the mouth C of each fault recognition switch circuit (2).
2, device according to claim 1 is characterized in that the cold end a of each insurance circuit RD or rd is connected to a grounding resistance R6.
