Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switch device, and more particularly to a switch device used in various vehicle-mounted devices such as power window switches.

[0002]

[Prior Art]

 With the recent trend toward higher quality, various new functions have been added to the switch devices of various in-vehicle devices mounted in automobiles.

Among them, a switch device such as a power window is provided with a night illumination function for each switch such as an operation button and an operation knob in order to improve visibility and operability at night.

[0004]

[Problems to be solved by the device]

 However, in such a switch device, although one or two light guides for guiding light from one light source to each of the switches at two to four places are provided, the light guide becomes large and its shape is complicated. Therefore, there is a problem that the illuminance and brightness of each switch vary greatly, and the die cost and the product cost are high.

It is also conceivable to provide a light for each switch without using a light guide, but this is not done in practice because it is costly, and the switch for the window for the driver's seat is not used. Often added illumination function only.

Therefore, the present invention has been made to solve such a problem, and provides a switch device in which parts such as a light guide are shared, the product cost is reduced, and the illuminance in the illumination part of each switch is uniform. The purpose is to

[0007]

In order to achieve the above object, in the present invention, a light as a light source, a plurality of illuminating parts illuminated by the lights, and a light gull that guides the light of the light to each of the illuminating parts. In the switch device including an id, the light is arranged at a position where the distance from each of the illumination units is the same, and the light guide is formed in the same shape.

[0008]

[Action]

 In the above configuration, the light is placed at the same distance from each illuminating section, and the light guide has the same shape, so the cost is reduced by sharing the light guide and the illuminance at each illuminating section is uniform. become.

【Example】

 Hereinafter, a power window switch device provided on a driver side of a vehicle will be described as an embodiment of the switch device according to the present invention with reference to the drawings.

FIG. 1 is a perspective view showing the outer appearance of the switch device. Power window switches 1 to 4 for opening and closing windows of a driver's seat, a passenger seat, and a rear seat, and a passenger seat are shown on the upper surface of the device. A window lock switch 5 that locks the opening and closing of windows in the rear seats and a door lock switch 6 that centrally locks the doors in each seat are provided.

By rotating the power window switches 1 to 4, the window lock switch 5 and the door lock switch 6 are electrostatically operated or vertically moved to perform a switch operation.

Further, on the upper surface of each of the switches 1 to 6, in order to display the position of each of the switches 1 to 6 due to the requirement of night visibility, for example, a color such as red or orange, and a half Illumination units 1a to 6a, which are made of a transparent light-transmitting member and illuminate through light from a light described later, are provided.

FIG. 2 shows a bottom view of this switch device as seen from below. This device is provided with lights 7 and 8 at two locations, and the light of the light 7 is illuminated by the light guides 1b, 2b. The light of the light 8 is guided to the respective switches 3, 4 via the light guides 3b, 4b while being guided to the respective switches 1, 2, 5, 6 via 5b, 6b.

The light guides 1b to 6b are made of a light-transmitting resin such as heat-resistant acrylic or polycarbonate, and may be made of a material such as an optical fiber. In the figure, 1c to 4c are switch mechanisms that perform a switch operation by operating each of the power window switches 1 to 4.

FIG. 3 shows a cross section taken along line III-III of the present device in FIG. 2, from which the light guided by the light guides 5b, 1b, 3b is illuminated by the switches 5, 1, 3. It can be seen that the parts 5a, 1a and 3a illuminate as shown by the broken lines in the figure.

FIG. 4 shows the relationship between the mounting positions of the lights 7 and 8 and the distances with respect to the distances between the respective illumination parts 1a to 6a.

In the present embodiment, as shown in (a), (A / 2) <B, that is, 1/2 of the distance A between the illumination units 5a and 1a is smaller than the distance B between the illumination units 1a and 3a. In this case, the light 7 is provided at the intersection point on the diagonal line of the quadrangle formed by the illuminating parts 1a, 2a, 5a, 6a which are at the same distance from the illuminating parts 1a, 2a, 5a, 6a, while 8 is provided on the side of the illumination units 1a and 2a with respect to the illumination units 3a and 4a, at a position apart from the illumination units 3a and 4a by A / 2 in the x direction. As a result, the distances from the respective illumination units 1a to 6a to the lights 7 and 8 serving as the respective light sources become constant.

Then, as shown in (b), when linearly guiding light from the lights 7 and 8 to the respective illuminating sections 1a to 6a as indicated by L1 to L6 in the figure, one kind of linear light guide is used. However, in this embodiment, since the light guides 1b to 6b that guide in a rectangular shape are used as indicated by L1 'to L6' in the figure, the light guides are 1b, 3b, 6b and 2b, 4b, 5b. Use two types of line symmetry.

On the other hand, as shown in (c), when (A / 2) ≧ B, that is, when 1/2 of the distance A between the illumination units 5a and 1a is equal to or greater than the distance B between the illumination units 1a and 3a, As in the case of (a), the light 7 is provided at the intersection point on the diagonal line of the quadrangle formed by the illuminating sections 1a, 2a, 5a, 6a, while the light 8 is provided for the illuminating sections 3a, 4a. It is provided on the opposite side of 2a from the illumination units 3a and 4a in the x direction by A / 2 and at the same distance from the illumination units 3a and 4a.

FIG. 5 shows the shape of the light guides 2b, 4b, 5b. (A) is a plan view of the light guides 2b, 4b, 5b as seen from above, and (b) is the light guides 2b, 4b, 5b. Is a side view as seen from the side, and (c) is a bottom view as seen from below the light guides 2b, 4b, 5b. As shown in (c), the light collecting parts of the lights 7, 8 are It has a circular cross section. Light guides 2b, 4b and 5b having such a shape are provided as shown in FIG. 2, while light guides 1b, 3b and 6b having a shape symmetrical to this shape are provided as shown in FIG.

As described above, in the present embodiment, as shown in FIGS. 1 to 5, the distances from the lights 7 and 8 which are the light sources to the respective illuminating parts which are the illuminating parts are the same, and the light guiding paths are also the same. Since two kinds of line-symmetrical light guides are assembled to guide the light of the lights 7 and 8 to the respective illumination parts 1b to 6b, only two kinds of light guides are required, and the product cost is reduced. The illumination in each of the illumination units 1b to 6b becomes uniform.

Further, when selecting a place to be illuminated, such as illuminating only the illuminating part of the power window switch in the driver's seat, or illuminating only the illuminating part of the power window switch in all seats, remove the light guide. This makes it easy to select the illumination unit.

In the present embodiment, two types of axisymmetric light guides are used for description, but in the present invention, as described with reference to FIG. 6a may be one kind of linear light guide that linearly guides light as shown by L1 to L6 in the figure, in which case the product cost is further reduced.

[0024]

[Effect of the device]

 As described above, according to the present invention, the distance from the light source, which is the light source, to each illuminating section, which is the illuminating section, is the same, and the light guides that guide the illuminating section from the light source have the same shape. By sharing the guide, the number of types of parts will be reduced, and the illumination in each illumination unit will be uniform, eliminating unevenness.

Further, when it is desired to illuminate only a certain part of the illuminating part, it is sufficient to remove the light guide that guides the illuminating part, so that the illuminating part can be easily selected.
