CN2568476Y - Automotive rear fog light controller - Google Patents

Abstract

The utility model relates to an automotive rear fog light controller which is characterized in that a position light switch K1 and a far-distance and short-distance light switch K2 are utilized to control the automotive rear fog light controller; the position light switch K1 and the far-distance and short-distance light switch K2 are matched with a normally close switch A2, a normally open switch A1, diodes D2, D1, a relay J and a relay contact JK to control the turning on and the turning off of a rear fog light 2. The utility model has the advantages of simple structure, convenient operation and high reliability and completely meets the GB475-1998 <The installation specification of external lighting and signal device of automobiles and trailers>, namely that only when a far-distance light, a short-distance light or a front fog light is turned on, the rear fog light can be turned on (4.3.14.7.1). The rear fog light can be independently turned off without influencing other lights (4.3.14.7.2); if only one of the following two requirements is met (4.3.14.7.3), the rear fog light can continuously work until a position light is turned off (4.3.14.7.3.1); after the position light is turned off, the rear fog light is in the turning-off state until the rear fog light is turned on again.

Technical field: the utility model relates to the Auto Rear Fog Lamp controller, also is applicable to trailer fog tail lamp controller.

The circuit of technical background: standard GB 4785-1998 " installation provision of automobile and trailer exterior illumination and signalling apparatus " 4.3.14.7 fog tail lamp is connected must meet following requirement:

4.3.14.7.1: have only when country beam, passing light or adverse-weather lamp are opened, fog tail lamp just can be opened.

4.3.14.7.2: fog tail lamp can be independent of any other lamp and close.

4.3.14.7.3: should satisfy following two and one of require:

4.3.14.7.3.1: fog tail lamp can continuous working, when the position lamp is closed till, be in closed condition afterwards, until opening once more always.

There is not the Auto Rear Fog Lamp controller that satisfies above-mentioned standard at present.

Summary of the invention:

The purpose of this utility model is to solve prior art can't satisfy the problem of GB4785-1998 about the fog tail lamp circuit requirement, provides a kind of simple in structure, easy to operate, the Auto Rear Fog Lamp controller that reliability is high.

Technical characterstic: the Auto Rear Fog Lamp controller comprises:

The lampet power supply is position lamp power supply 1 connection location light switch K1, position light switch K1 connects relay coil J, normally closed switch A2, normal open switch A1, and normal open switch A1 is a trigger switch, normal open switch A1 series diode D2, diode D2 connects country beam, passing light K switch 2, K2 ground connection 6;

The anodal normal open switch A1 that connects of diode D1, diode D1 negative pole connects fog tail lamp 2 and relay contact JK, the other end ground connection 6 of relay contact JK;

Fog tail lamp 2 connects power supply 5; Country beam, passing light 7 connect power supply 5, and country beam, passing light 7 connect country beam, passing light K switch 2;

The mouth 4 of the code light 8 one end connection location light switch K1 of indication fog tail lamp, the other end of code light 8 connects fog tail lamp 2 and relay contact JK;

Alphabetical lamp A1D, the A2D of indication normal open switch A1, normally closed switch A2 and instrument panel lamp and position lamp 3 are connected in parallel between the mouth 4 and ground 6 of position light switch K1.

Principle of work:

(1) the position light switch is arranged on 1 grade of the lamp handle of combined switch of external circuit,

(2) far away, low beam switch is arranged on 2 grades of the lamp handles of combined switch of external circuit.

A: the working process of opening fog tail lamp:

1 rotates the handle of combined switch, gets final product open position light switch K1, and the electricity of lampet power supply 1 is connected, and indicate alphabetical lamp A1D, the A2D of normal open switch A1, normally closed switch A2 bright this moment, and instrument panel lamp 3 is lighted.

2 open country beam, passing light K switch 2.Country beam, passing light 7 is lighted.

3 press normal open switch A1 button, connect the A1 switch, normal open switch A1 is a trigger switch, and current direction is: lampet power supply 1 → position light switch K1 → relay coil J → normally closed switch A2 → normal open switch A1 → diode D2 → country beam, passing light K switch 2 → ground 6 form the loop.

4, relay coil J get electric, contact JK adhesive, diode D1 connects, current direction is: lampet power supply → position light switch K1 → relay coil J → diode D1 → relay contact JK → ground 6 forms the loop.

Afterwards, normal open switch A1 disconnects at once, prepare to work next time, (A1 is a trigger switch), relay coil J, diode D1, relay contact JK switch on always.

5, fog tail lamp 2 is connected and is lighted, and after this, fog tail lamp continuous working is always lighted, and whether is opening or is closing regardless of country beam, passing light K switch 2, and fog tail lamp is all worked always and lighted.Current direction is: fog tail lamp power supply 5 → fog tail lamp 2 → relay contact JK → ground 6.

B: when wanting fog tail lamp independently to close, only need press normally closed switch A2, relay coil J dead electricity, relay contact JK disconnects, and fog tail lamp 2 extinguishes.

C: when position lamp K1 closes, relay coil J dead electricity, relay contact JK disconnects, and fog tail lamp 2 is just closed and is extinguished.

Advantage of the present utility model:

Do not need peripheral auxiliary element, simple in structure, easy to operate, the reliability height.

The circuit connection request that meets standard GB 4785-1998 " installation provision of automobile and trailer exterior illumination and signalling apparatus " 4.3.14.7 fog tail lamp:

4.3.14.7.1: have only when country beam, passing light or adverse-weather lamp are opened, fog tail lamp 2 just can be opened, and opens afterwards always.
