Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a power window operating device used to operate an automobile power window.

[Conventional technology]

The electrical circuit of a conventional power window operating device of this kind is as shown in Fig. 6, where 1 is a main switch unit installed near the driver's seat, and 2 is a main switch unit installed near the passenger seat or rear seat. The sub-switch unit 1 is equipped with an operation lock switch 3 and a first switch 5 for operating a window opening/closing motor 4 inside the main switch unit 1. A second switch 6 for operating the motor 4 is provided inside the window, and by operating the first switch 5, the window can be opened or closed regardless of whether the lock switch 3 is turned on or off. The switch 6 prevents the window from opening or closing when the lock switch 3 is open, thereby increasing safety during driving.

[The problem that the idea attempts to solve]

However, since the on/off state of the lock switch 3 is not known to those in the vicinity of the sub-switch unit, opening of the lock switch causes the second
If the window does not open or close even if the second switch 6 is operated, there is a problem in that it cannot be determined whether the second switch is malfunctioning or is inoperable.

[Means to solve the problem]

The present invention was devised in order to eliminate such problems, and in particular, the sub-switch unit is equipped with an indicator lamp that lights up when the lock switch included in the main switch unit is closed. It is an object of the present invention to provide a power window operating device that can clearly indicate the open or closed state of a lock switch in a sub-switch unit.

[Example] The present invention will be explained in detail below based on the example shown in FIGS. 1 to 5. The same parts of the structure in this example and the structure shown in the conventional example are The reference numerals cited in the example will be used, and the explanation of the same parts will be omitted.

That is, as shown in FIG. 1, the power window operating circuit of this embodiment has an indicator lamp 7 installed in the sub-switch unit 2 that is turned on when the lock switch 3 provided in the main switch unit 1 is closed. The configuration of the sub-switch unit 2 incorporating this indicator lamp 7 is as follows. The embodiment shown in FIGS. 2 and 3 is
A mounting recess 9 for attaching the indicator light 7 is formed in a part of the switch case 8, and the indicator light 7 is placed inside the recess 9.
Attach. Also, on the top of the switch case 8,
Guide lights 12 formed with a window 11 that avoids an operation knob 10 are superimposed, and a finisher 14 formed with a display 13 for transmitted illumination is superimposed on the upper surface of the guide lights 12.

Therefore, according to this embodiment, the lock switch 3
An indicator light 7 that lights up when the switch is closed is provided in the switch case 8, and the lighting state of the indicator light 7 can be visually seen through the finisher 14. It is easy to know whether the lock switch is closed or opened.

In the embodiment shown in FIGS. 4 and 5, a see-through window 18 is formed in the switch base 15 through which a light emitting element 17 connected to a printed circuit board 16 and which emits light when the lock switch 3 is closed, can be seen through.
An operation knob support shaft 19 is provided, and the operation knob 20 supported by this support shaft 19 is made of a transparent or translucent material. Further, the see-through window 18 is formed to be located inside the operation knob 20.

Therefore, according to this embodiment, the lock switch 3
Light is emitted by the closed circuit. A light emitting element 17 is provided, and the light emitted from the light emitting element 17 passes through the transparent window 18 and illuminates the back side of the operating knob 20. Therefore, when the operating knob 20 is illuminated, the lock switch 3 is illuminated. It is obvious at a glance that is a closed circuit.

[Effect of idea]

As described above, according to the power window operating device according to the present invention, since the sub-switch unit is equipped with an indicator light that lights up or emits light when the lock switch provided in the main switch unit is closed, it can be operated in the passenger seat or rear seat. This has the effect that a person can very easily confirm whether the lock switch is closed or open by looking at the display mode of the indicator light.
