Abstract

PURPOSE:To simplify the structure of a car with cornering lamps by connecting cornering lamps in parallel between the electric source and a turn-signal switch of a turn-signal lamp circuit with each element connected in series. CONSTITUTION:When a light switch 20 is on and a turn-signal switch 43 is turned to an R-side to light a right-turn signal lamp 52, a right-cornering lamp 32 as well as the lamp 52 and a unit 50 are connected, and right lamps 52 and 32 are respectively lit. When the turn-signal switch 43 is set to L, left lamps are lit. This construction permits to simplify the structure, since the turn-signal lamp and the cornering lamp can be simultaneously switched over only by the operation of a turn signal switch 43.

Description

[Detailed description of the invention] The present invention relates to a phantom fire device for a vehicle.

Among the automatic φ types, there is one that has a Copling lamp. This cornering lamp is Radius Xr-
A 'lamp that is fixedly installed on the outside of each moe light placed near Tagril, and when the turn signal lamp is flashing, it is installed on the same side as the turn signal lamp. There is a lamp that lights up.

When the automatic vehicle turns left or right, the cornering lamp on the side where the turn signal lamp is flashing lights up the field of view in the direction of the turn, ensuring visibility in the direction of travel and making it easier to drive at night. are doing.

In controlling the lighting of the cornering lamps, the lamps on the same side as the turn signal lamps are operated, and the operation thereof is different from that of the turn signal lamps.

On the other hand, a turn signal switch is generally used to switch the Ishikawa and left turn signal lamps. A new switch has been added to this turn signal switch, which is operated in the same way by the turn signal switch lever, and this makes it possible to switch and control the Ishikawa and left cornering lamps. In this case, since two switches must be provided, there is a problem that the structure of the switch becomes complicated.

Therefore, in order to simplify the turn signal switch of the circuit for lighting the turn signal lamp and cornering lamp, the present invention provides a power supply, a turn signal unit, a turn signal lamp, and a turn signal switch.
Connect in series between the power supply and the turn signal switch,
The circuit has a circuit configuration in which cornering lamps are connected in parallel, and one I/J switching contact of the turn signal switch is used to operate the cornering lamp.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings. Note that the same members are given the same reference numerals. FIG. 1 is a circuit diagram showing an embodiment of the present invention. A battery 10 and a light switch 20 are connected in series, and a left circular cornering lamp 31 is connected between the light switch 20 and the h terminal 41 of the turn signal switch/IO.

An Ishikawa cornering lamp 32 is connected between the light switch 20 and the Ishikawa terminal 42 of the turn signal switch 40. Further, a turn signal unit 50 is connected after the unit 10, a left circular turn signal lamp 51 is connected between the turn signal unit 50 and the right terminal 41, and a left circular turn signal lamp 51 is connected between the turn signal unit 50 and the right terminal 42. An Ishikawa turn signal lamp 52 is connected between them.

That is, the turn signal lamps 51, 52 and the turn signal lamps 31, 32 are connected in parallel with each other, and these lamps 51, 52, 31, 32 are connected in series with the turn signal switch 40.

The turn signal unit 50 is a known unit that conducts intermittently at a predetermined period. turn signal switch 40
is a type of changeover switch, and its equivalent circuit is shown in FIG. 2 together with other circuits. 43 is a turn signal switch.

That is, when the turn signal switch 40 is in the state shown by the solid line in FIG. 1, the movable contact of the turn signal switch 43 is connected to the contact R as shown in FIG. 2, and the turn signal switch 40 is in the state shown in FIG. In the state shown by the broken line, the movable contact of the turn signal switch 43 is connected to the contact.

Next, the operation of the above embodiment will be explained. First, let's say that the light switch 20 is turned on. Here, by using a turn jig pull lever (not shown), the turn signal switch 40 is moved so that the left circular turn signal lamp 51 blinks.
Set. That is, the setting is made as shown by the broken line in FIG. 1 (with the turn signal lamp 1-43 shown in FIG. 2 switched to the contact state). As a result, the external turn jig pull lamp 51 and the U turn signal unit 50 become conductive, so the left circle turn signal lamp 51 blinks, and the h cornering lamp 31 becomes conductive, so the Furukawa]-f ring lamp 31 becomes conductive. White lights.

Next, the turn signal switch 40 is set using the turn signal lever so that the Ishikawa turn signal lamp 52 is turned off. The t-line is also set as indicated by the solid line in FIG. 1 (turn signal switch 4.3 in the state shown in FIG. 2). As a result, the useful turn jig pull lamp 52 and the U turn signal unit 50 become conductive, so
The Ishikawa cornering lamp 32 is redone because the Ishikawa cornering lamp 52 blinks and the Ishikawa cornering lamp 32 becomes conductive.

In this way, by operating the turn signal switch 40 once, the turn signal lamp 51 or 52
The turn signal switch 40 and the cornering lamp 31 or 32 can be switched at the same time, and the conventional turn signal switch 40 can be used as is.

FIG. 3 is a circuit diagram showing another embodiment of the present invention. This embodiment uses normally open relays 61.62 to connect turn signal lamps 51.52 and cornering lamps 31.3.
2 are linked to each other. A normally open relay 61 is connected between the left circular cornering lamp 31 and the left circular terminal 41.
The coil is connected, and the other contact is connected between the left circular turn signal lamp 51 and the turn signal unit 50. Also, Ishikawa cornering lamp 32 and Ishikawa terminal 42
A coil of a normally open relay 62 is connected between the two, and its contacts are connected between the Ishikawa turn signal lamp 52 and the turn signal unit 50.

Next, the operation of the embodiment F will be explained. When the turn signal switch 40 is set as shown by the solid line in FIG. 3, the 1-]-nulling lamp 31 lights up, and the relay 61 is turned on, so the h turn jig full lamp 51 flashes. . Conversely, when the turn signal switch 40 is set as indicated by the broken line 7 in FIG. Flashing.

-1- As stated above, the present invention provides a turn signal lamp and =
1-The knarling lamp is connected in parallel, and the turn signal lamp and the turn signal switch are connected in series, so the turn signal lamp and the cornering lamp can be switched simultaneously using the conventional turn signal switch. It has the effect of being controllable.
