Abstract

The utility model relates to a vehicle light on-off indicator which is mainly composed of a sounding alarm device and one to a plurality of detecting control display device. The utility model is suitable for alarming and indicating fault circuits when the light circuit and the lamp of automobiles and other motor-driven vehicles take place faults and work abnormally, the utility model has the advantages of simple structure, and high work adaptability and stability, and the utility model adopts synchronous alarm indication of sound and light and is easy to discover faults in time.

Description

Vehicle light on-off indicator

The utility model relates to that power actuated vehicle light circuit such as a kind of automobile is disconnected, under the open fault, bad failure condition of lamp, the prompting displaying alarm.

At present, light or line faults such as power actuated vehicle exterior illumination, indication such as automobile, fail by driver's operation will luminous (personnel that sail of department are difficult for again finding in operator's compartment), be a big factor that causes traffic accident, though there are some detection type to occur now like the device of fault, owing to complex structure, cost height, repacking difficulty, particularly the relay contact formula is not suitable for the strong running environment of evil that vehicle jolts, poor stability, so that can not really achieve the goal, use.

The purpose of this utility model designs exactly and provides that a kind of operation conditions is stable, cost is low, simple in structure, and installs or reequip disconnected, the open fault prompting device of vehicle light easily.

The utility model is to realize like this, it comprises that an acoustic warning device and 1～a plurality of detection control read out instruments that insert each bar lamp wiring respectively connect and form, detect the control read out instrument and seal in lamp wiring, according to its running current, carry out voltage sampling relatively, during normal operation, this prompting device is failure to actuate, (it is very little to consume energy) after light and circuit closure.Otherwise it is bright to detect control read out instrument display lamp, marks faulty line, drives acoustic warning device work simultaneously, sends the sound acoustic alarm, finds with the prompting navigating mate.

Accompanying drawing 1, the utility model structural representation (detecting the control read out instrument with is example).

Among the figure, K is the lamp wiring switch, ZD ₁, ZD ₂Expression car lighting or indicator lamp, e, c, d represent three utmost points of aerotron GB, 1～three-terminal voltage-stabilizing source, the 2-integrated package, the 3-rattler, 4-acoustic warning device, 5-detect the control read out instrument.

Describe concrete structure of the present utility model and working process in detail below in conjunction with accompanying drawing.

The utility model is connected and is formed by an acoustic warning device and 1～a plurality of detection control read out instruments that insert each bar lamp wiring respectively, wherein acoustic warning device is made up of three-terminal voltage-stabilizing source 1, integrated package 2, rattler 3, rattler 3 is connected to the mouth of integrated package 2, the working power end of integrated package 2 and be connected to the mouth in the three-terminal voltage-stabilizing source between lamp wiring power supply and the ground; Detect the control read out instrument by resistance R ₁, R _X, aerotron GB, luminotron (indicator lamp) LED, photoelectrical coupler GD form, and are connected between the e utmost point and the c utmost point of GB GB and the C utmost point R that connects again behind the input end of LED series connection GD ₁Ground connection, R _XBe sample resistance, be connected between the e utmost point and the b utmost point of GB, be serially connected with together in the K switch lamp wiring afterwards, and the mouth of GD is connected to the trigger end of integrated package 2.

When using the utility model, a plurality of GD mouths of read out instruments are controlled in 1～a plurality of detections, and meet out the trigger end of the integrated package 2 of acoustic warning device, a plurality of R _XBe serially connected with in the circuit after the K switch of a plurality of lamp wirings respectively, and the difference of electric current is got different resistance values during according to each circuit normal operation, the conducting-state voltage of GB is a bit larger tham or equals in its pressure drop when guaranteeing its circuit normal operation.

Closed K is when the lamp wiring normal operation, according to R _XValue, its pressure drop is more than or equal to the conducting-state voltage of GB, the GB conducting is because V _ECBe about 0 volt, approximate short circuit, so the GD no-output of being failure to actuate, LED is not luminous, integrated package 2 triggerless, squealer 3 sounding of being failure to actuate; When circuit or lamp or any lamp damage when not working, flow through R _XElectric current reduce until being zero, this moment R _XOn pressure drop end then LED, GD, R less than the conducting-state voltage GB of GB ₁, the branch road conducting, the luminous indication of LED, GD work simultaneously has output to trigger, integrated package 2 has output, rattler 3 sounding alarms.

When multichannel light was worked simultaneously, when 1 or 1 above circuit or lighting fault, rattler 3 was reported to the police, and represents that simultaneously the indicator lamp of each faulty line is luminous, can accurately indicate faulty line.Be convenient to navigating mate and in time find, so that maintenance guarantees the light normal operation.
