Description

Automotive headlight switch

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headlight switch for an automobile. More particularly, the present invention relates to an automobile headlight switch capable of preventing misoperation and increasing driving convenience by employing a slide type headlight switch.

The lighting device of a vehicle may be classified into a light lamp, a traffic light, and an indicator light. Here, the lamp includes a headlight for illuminating the front area of the vehicle, and a reversing lamp for illuminating the rear area when reversing, and there are other fog lamps used when raining or passing through the fog area, and indoor lights for lighting in the cabin. .

In addition, the head light is classified into an upstream beam and a downbeam according to the irradiation distance and the direction, and the upstream beam is irradiated far away because the irradiation distance is longer than that of the downward beam. In this way, the upward beam widens the driver's field of view by illuminating a wider distance, but is used only in special cases because it interferes with the driver of the oncoming vehicle.

1 is a perspective view showing the configuration of a conventional headlight switch, in which a rotary cover 2 is mounted on a switch lever 1 fixed to a steering column, and then the rotary cover 2 is rotated as necessary to control the headlamp. It is a way to light. When the driver rotates the rotary cover 2, which is in the off state, by one level at night driving, the driver illuminates the instrument panel and the audio and lights it in the first stage of the tail light and the headlight. In this state, if the rotary 2 is rotated one step further, the headlight is in a two-stage state, and the front region is irradiated by turning on the above-mentioned downward beam.

The conventional automotive headlight switch having such a configuration adopts a rotary method, and therefore, if the driver is unfamiliar with the characteristics of the vehicle or a novice driver, the headlight switch may be incorrectly operated. Since it is always kept constant, people often get off with their headlights on.

Normally, the up and down beams are configured to automatically turn off when the key is turned off and the starter is turned off. However, since the battery power is still supplied even when the engine is stopped, the first stage of the headlight is maintained as it is. There is a problem that the battery is discharged by continuously lighting the instrument panel lamp.

In order to solve the above problems, the present invention lights up the headlight while pushing the slide cover sliding along the switch lever, so that the operation is smooth and the length of the cover changes according to the lighting state, so that the driver can easily turn on the current headlight. It is an object of the present invention to provide a headlight switch for an automobile that can prevent the discharge of the battery by determining the state.

The slide cover 20 is adopted to increase the convenience of operation.

When driving at night, the driver advances the slide cover 20 which is in an off state by one step along the switch lever 10 toward the steering column, and lights up the tail light and the headlight 1 stage while illuminating the instrument panel or audio. . In this state, when the slide cover 20 is advanced one step further, the headlight is in a two-stage state, and the front beam is irradiated by lighting the downward beam, and the detailed structure thereof is shown in FIGS. 3 and 4 below. This is explained in

First, as shown in FIG. 3a, a guide groove 24 having a plurality of insertion grooves 24a to 24d along the longitudinal direction is formed on an inner surface of one front half of the slide cover 20 of the present invention. A moving contact 26 is provided on the inner surface of the other half portion which is disposed opposite to the guide groove 24. In addition, a locking end 20a is formed at the end of the switch lever 10 near the steering column, and the end of the switch lever 10 is blocked by the shielding film 20b to protect the internal components. .

Next, as shown in FIG. 3, the first to fourth insertions are slid along the guide grooves 24 of the slide cover 20 described above to one side outer surface of the switch lever 10 provided in the steering column. The elastic ball 12 which is selectively inserted into the grooves 24a to 24d is mounted. In addition, the other side disposed opposite to the elastic ball 12 is selectively made in contact with the movable contact 26 of the above-described slide cover 20 to maintain the energized state, the agent for lighting the headlight in one or two stages The 1st fixed contact 14 and the 2nd fixed contact 16 are provided.

Here, the elastic ball 12 is elastically supported by the spring 28, as shown in detail in Figure 4a, so that the insertion groove (24a ~ 24d) of the guide groove 24 at all times that no external pressure It was to remain inserted in one of the states. In addition, since the first fixed contact point 14 is formed longer than the second fixed contact point 16, when the movable contact point 26 and the first fixed contact point 14 are connected, the headlight 1 stage is turned on. When the moving contact 26 and the first fixed contact 14 and the second fixed contact 16 are connected at the same time, the headlights are turned on in two stages to light up the down beam.

In addition, as shown in FIG. 4B, the second insertion groove 24b and the third insertion groove 24c formed in the guide groove 24 of the slide cover 20 are vertically disposed, and the second insertion groove ( The elastic ball 12 inserted into the 24b) is formed in a curved shape so that the elastic ball 12 can be lowered into the third insertion groove 24c by its own weight.

Next, referring to FIGS. 3A to 4B, the operation process of the slide type headlight switch of the present invention will be described. The slide cover 20 of FIG. 3A and the switch lever 10 of FIG. 3B are understood. In order to assist, the moving process of the elastic ball 12 and the moving contact 26 is shown in phantom lines.

First, as shown in FIG. 3A, when the elastic ball 12 is positioned at the first position P1, the movable contact 26 of the slide cover 20 is moved to the first position (as shown in FIG. 3B). P1 '), since the moving contact 26 and the fixed contact 14, 16 are not connected, the headlamp remains off.

Next, as shown in FIG. 3A, when the elastic ball 12 moves to the second position P2 by pushing the switch lever 10, the movable contact 26 of the slide cover 20 is shown in FIG. 3B. As shown in the drawing, the second position P2 'is positioned. At this time, the movable contact 26 and the first fixed contact 14 are connected to the first stage of the headlight, thereby lighting the tail light, the instrument panel, and the audio. .

At this time, the elastic ball 12 is slid from the second insertion groove 24b to the third insertion groove 24c by its own weight, that is, move to the third position P3 shown in FIG. At the same time, the movable contact 26 or 3b moves to the third position P3 ', as shown in FIG. 3, where the end of the movable contact 26 is still in contact with the first contact 14. The 1 st lighting state of the headlight is continuously maintained. If the headlights are to be turned off in this state, the slide cover 20 may be pulled out of the steering column. Accordingly, the elastic ball 12 is moved from the third insertion groove (24c) to the first insertion groove (24a) while sliding along the curved portion 22 of the guide groove (24), the moving contact 26 is The connection state between the first fixed contacts 14 is released by moving to one position P1 '.

Conversely, as shown in FIG. 3A, when the slide cover 20 is pushed again toward the switch cover 10, the elastic balls 12 move from the third position P3 to the fourth position P4. Accordingly, the movable contact 26 is moved to the fourth position P4 ', as shown in FIG. 3b, so that the movable contact 26, the first fixed contact 14, and the second fixed contact 16 are simultaneously. By being connected and being in the headlight two-stage state, not only the tail lamp and the instrument panel but also the down beam are lit, the front area can be irradiated.

In this state, to turn off the headlight, the slide cover 20 may be pulled out of the steering column. Accordingly, the elastic ball 12 is slid along the curved portion 22 of the guide groove 24 via the third insertion groove 24c from the fourth insertion groove 24d to the first insertion groove 24a. By moving, the connection between the movable contact 26, the 1st fixed contact 14, and the 2nd fixed contact 16 is canceled, and a headlamp is turned off.
