Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a daylight passing switch device that simultaneously lights up the rear photo lights when the low beam lights are turned on.

2. Description of the Related Art In some regions, it is mandatory for automobiles to turn on rear fog lights when low beam lights are turned on. On the other hand, in automobiles, when switching from low beam lights for passing at night to high beam lights for passing, in order to avoid a dark zone where both the low beam lights and high beam lights turn off, the switch is switched to low beam lights. Both the low beam switch means for energizing and the passing switch means for energizing the high beam lights are turned on. However, when passing is performed during the daytime, the short-circuit switch means for shorting the writing switch is turned on in synchronization with the passing switch means to supply power instead of the writing switch, so that the passing time is reduced. When switching, the low beam lights and rear photo lights turn on, causing complaints from users.

The present invention has been made in view of the above circumstances, and its purpose is to provide a daylight passing switch device that can prevent low beam lights and rear fog lights from turning on when a passing operation is performed in the daytime.

To summarize, the present invention is characterized in that the shorting switch means for shorting the lighting switch when switching from the low beam position to the passing position is turned on after the low beam switch means is turned off.

A locking piece 4b is provided at the tip of the movable contact piece 4 for the low beam so as to project downward. In this case, the high beam movable contact piece 2 is set to be displaced downward due to its own springiness, and the low beam movable contact piece 4 is set to be displaced upward due to its own springiness. 5 is a stopper member;
A latching protrusion 5a is protruded from above to face the latching piece 4b of the movable contact piece 4 for the low beam in the middle thereof, and the tip of the movable earthing contact piece 3 is provided on the upper end surface of the latching protrusion 5a. part is placed and locked. Reference numeral 6 denotes a fixed grounding contact piece made of a leaf spring disposed above the contact portion 2a of the movable contact piece 2 for high beam, and 7 is disposed above the contact portion 3c of the movable grounding contact piece 3. This is a fixed contact piece for pasting. The high beam movable contact piece 2 and the grounding movable contact piece 3 constitute high beam switching means 8, the high beam movable contact piece 2 and the grounding fixed contact piece 6 constitute passing switch means 9, and the low beam The moving movable contact piece 4 and the movable grounding contact piece 3 constitute a low beam switching means 10, and the fixed passing contact piece 7 and the movable earthing contact piece 3 constitute a shorting switch means 11. Reference numeral 12 denotes a push rod that is moved up and down by the operation of an operating lever (not shown), which passes through the movable contact piece 4 for the low beam, and has a pushing protrusion 12a protruding from its tip that passes through the movable contact piece 3 for grounding. At the same time, a flange portion 12b is formed between the grounding movable contact piece 3 and the low beam movable contact piece 4.

Now, the configuration of the electric circuit will be described according to FIG. 13 is a battery, its negative terminal is grounded, and its positive terminal is branched into two via a fuse 14 and a lighting switch 15, the first branch end of which is connected to a high beam light 16 and a high beam switch means 8 or a passing switch means. 9, and the second branch end is connected to the low beam light 17 and the low beam switch means 10.
The high beam light 17 is connected to the ground via a rear fog light 18 in parallel. 19 is a relay, the excitation coil 20 of which is connected between the positive terminal of the battery 13 and the ground via the short circuit switch means 11 in series;
A normally open relay switch 21 is connected in parallel to the lighting switch 15.

Next, the operation of this embodiment will be explained.

In the high beam position when the operating lever is moved to the lower position, as shown in FIG. 2 is displaced downward by its own spring property, and its contact portion 2b comes into contact with the ground movable contact piece 3a, and the high beam switch means 8 is turned on. Therefore, if the lighting switch 15 is turned on at night, the high beam light 16 is energized via the lighting switch 15 and the high beam switch means 8 and turns on.

Furthermore, when the operating lever is operated upward from the high beam position to the middle low beam position, the pressing force on the low beam movable contact piece 4 by the flange 12b of the push rod 12 is released, as shown in FIG. The low beam movable contact piece 4 is displaced upward by its own spring property, and the contact portion 4a comes into contact with the contact portion 3b of the grounding movable contact piece 3, and the low beam switch means 10 is also turned on. As a result, the low beam light 17 and the rear photo light 18 are energized and turned on via the lighting switch 15 and the low beam switch means 10, and accordingly, the high beam light 16 and the low beam light 17 are both turned on. Thereafter, when the operating lever is further operated upward to the low beam position, the high beam movable contact piece 2 is pressed by the pressing protrusion 12a of the push rod 12 and displaced upward, as shown in FIG. 2b is separated from the contact portion 3a of the movable ground contact piece 3, and the high beam switch means 8 is turned off. As a result, the high beam light 16 is cut off and turned off, and the low beam light 1
7 and the rear photo light 18 will continue to be lit.

Now, when the operating lever is operated further upward from the low beam position to the upper pushing position, the pushing rod 1 will move as shown in Figure 4.
The pressing protrusion 12a of 2 presses and displaces the high beam movable contact piece 2 further upward, and the contact part 2a contacts the grounding fixed contact piece 6, and thus,
The switching means 9 for passing is turned on. As a result, the high beam light 1 is turned on via the lighting switch 15 and the passing switch means 9.
6 is energized and lights up, and high beam light 1 is turned on again.
6 and low beam light 17 are both turned on.
Thereafter, when the operating lever is further operated upward to the pushing position, the high beam movable contact piece 2 is further pressed upward by the pressing protrusion 12a of the push rod 12, as shown in FIG. , the grounding fixed contact piece 6 made of a leaf spring is displaced upward from the original position shown by the two-dot chain line in a state in which it is in contact with the contact portion 2a. At the same time, the flange 12b of the push rod 12 presses the grounding movable contact piece 3 and displaces it upward, thereby causing the contact part 3b to move to the low beam movable contact piece 3.
The low beam switch means 10 is turned off, and then the contact part 3c is moved away from the contact part 4a.
contacts the fixed contact piece 7 for passing, and the short circuit switch means 11 is turned on. As a result, the low beam light 17 and the rear photo light 18 are cut off and turned off, and the relay 1
The excitation coil 20 of No. 9 is energized via the short-circuiting switch means 11, and the relay 19 operates to turn on the relay switch 21. The relay switch 21 turns on the lighting switch 15.
is shorted. Therefore, lighting switch 1
The high beam light 16 continues to be energized via the relay switch 5 or the relay switch 21 and the switching means 9 for switching on. Thereafter, when the upward operating force on the operating lever is released, the operating lever automatically descends and returns to the middle low beam position. Therefore, each switch means passes through the state shown in FIG. The low beam state shown in the figure is restored, and the low beam light 17 and rear fog light 18 are turned on. And the third
Passing is performed by repeating the states shown in FIGS.

By the way, since the lighting switch 15 is turned off in the daytime, even if the lighting switch means 9 for flashing and the switch means for low beam 10 are turned on in the states shown in FIGS. 3 to 4 to perform flashing, the high beam light 16 ,
Low beam light 18 and rear photo light 1
8 is not energized, and then when the state shown in FIG. 4 is changed to the state shown in FIG. The switch 21 short-circuits the lighting switch 15, and the high beam light 16 is energized via the relay switch 21 and the passing switch means 9, and is turned on.

According to this embodiment, the low beam switch means 10 is configured to prevent a dark zone from occurring in which both the high beam lights 16 and 17 are not turned on when switching the operating lever from the low beam position to the passing position at night.
Even if both the and passing switch means 9 are turned on, at the time of switching, the shorting switch means 11 is turned on after the low beam switch means 10 is turned off, and the relay switch 21 of the relay 19 short-circuits the lighting switch 15. As a result, the low beam lights 17 and rear photo lights 18 will not turn on even temporarily when passing during the day.
Therefore, the problem of complaints from users can be solved.

In the above embodiment, the relay switch 21 was connected in parallel to the lighting switch 15, but instead, the relay switch 21 was connected in parallel to the lighting switch 15.
may be connected in parallel to the short-circuiting switch means 11.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the invention.

As explained above, in the present invention, when performing a passing operation, the shorting switch means is turned on after the low beam switch means is turned off, thereby shorting the lighting switch. Also, it is possible to provide a daylight switching device that has the practical effect of not turning on the rear lighting.
