Description
Technical field
The utility model relates to a kind of emergent pole changer, belongs to car bulb control field.
Background technology
When automobile is often opened emergency light at foggy weather or in the middle of travelling rainy day, i.e. automobile four corner lamps.Also need to open emergency light in fleet's driving process in addition.Entirely ineffective when turning to about in the unlatching emergency light travels, running into.Turn to about wanting and to turn off the emergency circuit switch, open left and right sides pole changer again and could show left and right sides steering indicating light.The driver brings a lot of inconvenience in driver behavior like this.Be exactly in addition turn to about emergency light is beaten when overtaking other vehicles under steam more loaded down with trivial details.Existing emergent pole changer generally is to be connected in series normally closed switch in the automobile emergency lamp switch connects control circuit, and this normally closed switch is connected the starting switch formation linked switch of a left side in the control circuit or right turn lamp with a left side or right turn lamp switch.Thisly can effectively avoids neglecting the traffic accident that causes and take place, but owing to adopt the mechanical type linked switch, the life-span is not long because of light indication, operate insensitive, poor stability.
The utility model content
The purpose of this utility model is to provide a kind of emergent pole changer, and manual dexterity is easy to use, long service life.
Emergent pole changer described in the utility model, comprise emergency button, left and right sides pole changer, left and right sides steering indicating light and flasher circuit, its left side, the right turn switch is respectively with first, second relay is connected in series between the power supply, first, the normally-closed contact of second relay is connected with the 3rd relay, then and emergency button be connected in series between the power supply, the output of flasher circuit is respectively by first, the normally opened contact of second relay connects a left side, right turn lamp, the output of flasher circuit also connect a left side respectively by the normally opened contact of the 3rd relay, the right turn lamp.
Wherein flasher circuit is generally impulse circuit, is common prior art.
Wherein: the circuit of emergency light pole changer comprises emergency button S1, left and right sides pole changer S2, relay K M1, KM2, KM3 and contact thereof, left steering lamp L1, right turn lamp L2, battery B1, the R end of left and right sides pole changer S2 and L end are respectively by relay K M1, KM2 is connected the two ends of battery B1, emergency button S1 successively with the normally closed switch J1-2 of relay K M1, the normally closed switch J2-2 of relay K M2, relay K M3 is connected in series in the both sides of battery B1, the normally opened contact J1-1 of relay K M1 is earlier in parallel with the normally opened contact J3-1 of relay K M3, be connected the output of flasher circuit then with left steering lamp L1, the normally opened contact J2-1 of relay K M2 is earlier in parallel with the normally opened contact J3-2 of relay K M3, is connected the output of flasher circuit then with right turn lamp L2.
The utility model pole changer of meeting an urgent need, by the relay that is mutually related is set in the original steering indicating light circuit of automobile, emergency light circuit and flasher circuit, make in bad weather, turn to about perhaps needing in other emergency light open modes or when overtaking other vehicles, can directly open left and right sides steering indicating light, solve loaded down with trivial details, easy to use in the driver behavior.Since adopt the relay association, manual dexterity, and reaction is fast, long service life.
Description of drawings
The circuit theory diagrams of Fig. 1, the utility model one embodiment.
Among the figure: normally-closed contact J3-1, the J3-2 of normally opened contact J2-2, the relay K M2 of normally-closed contact J2-1, the relay K M2 of normally opened contact J1-2, the relay K M1 of S1, emergency button S2, left and right sides pole changer B1, battery L1, left steering lamp L2, right turn lamp KM1-KM3 relay J 1-1, relay K M1, the normally opened contact of relay K M3.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in Figure 1, the R of left and right sides pole changer S2 end and L end are connected the two ends of battery B1 respectively by relay K M1, KM2.Emergency button S1 is connected in series in the both sides of battery B1 successively with normally closed switch J2-2, the relay K M3 of normally closed switch J1-2, the relay K M2 of relay K M1.The normally opened contact J1-1 of relay K M1 is earlier in parallel with the normally opened contact J3-1 of relay K M3, is connected the output of flasher circuit then with left steering lamp L1.The normally opened contact J2-1 of relay K M2 is earlier in parallel with the normally opened contact J3-2 of relay K M3, is connected the output of flasher circuit then with right turn lamp L2.
Operation principle:
Under the normal condition when not needing to open emergency light, during left steering, left and right sides pole changer S2 is got on the L side, relay K M1 gets electric, normally opened contact J1-1 closure, and normally-closed contact J1-2 disconnects, flasher circuit is connected left steering lamp L1 from A, and have only left steering lamp L1 shinny this moment.Right turn in like manner.
When need opening emergency light, normally closed, the KM2's of closed emergency button S1, KM1 is normally closed, and relay K M3 gets electric, closed normally opened contact J3-1, J3-2, and left and right sides steering indicating light L1, L2 are simultaneously bright.
Opening under the emergency light state, when needing left steering, pole changer S2 gets on the L side with the left and right sides, and relay K M1 gets electric, normally opened contact J1-1 closure, normally-closed contact J1-2 disconnects, flasher circuit is connected left steering lamp L1 from A, while relay K M3 dead electricity, and normally opened contact J3-1, J3-2 disconnect, disconnect right turn lamp L2, have only left steering lamp L1 shinny this moment.Opening under the emergency light state, when needing right turn in like manner.
