Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a switch device for a vehicle having a switch such as a fan switch that can be switched to a desired function by circular motion.

[Prior Art] Switches capable of switching to a desired function by circular movement have been conventionally provided on the interior components of an automobile, for example, on the instrument panel. A typical example is a fan switch device for controlling the temperature inside the passenger compartment of an automobile. Figures 8 and 9 show schematic configuration diagrams of a conventional vehicle fan switch device. Figure 8 is a plan view of a conventional vehicle fan switch device, and shows a configuration in which a manual fan switch 14-1 having a switching lever 12-1 capable of switching by circular movement protruding from a front panel 10 is fixedly supported on a switch board 16. The manual fan switch 14-1 is fixed to the switch board 16.
As means for fixing and supporting the manual fan switch 14-1 to the switch base plate 16, four lateral guides 18 which allow the manual fan switch 14-1 to move in the fore-and-aft direction, i.e., in the direction b in the figure, but which restrict movement in the lateral direction, i.e., in the direction a in the figure, and front and rear stoppers 20, 21 which restrict movement of the manual fan switch 14-1 in the direction b in the figure are integrally formed on the switch base plate 16.

The vehicle operator slides the switching lever 12-1 in an arc shape in the direction c in the figure, and moves the switching stage 24 displayed along the lever slit portion 22 shown in the front view of FIG.
(In the figure, for convenience, the temperature is set to three stages: Off, Lo, and Hi.) By setting the switch to a predetermined position, it is possible to manually set the temperature inside the vehicle to a desired temperature.

[Problems to be Solved by the Invention] However, vehicle users may desire a fan switch that has an auto mode that can automatically set the temperature inside the vehicle, instead of such a manual mode fan switch. In this case, it is necessary to replace the Off-Lo-Hi three-stage manual fan switch 14-1 with the Off-Auto-Lo-Hi four-stage automatic fan switch 14-1 shown in Figure 8. In the conventional vehicle fan switch device shown in the figure, the auto fan switch has to be fixed at the same position as the manual fan switch, and as a result, as shown in Figure 10, the difference in the number of switching steps between the two switches causes lever slit part 2
The swing width of the switching lever at 2 (in the figure, the switching position of the switching lever of the manual fan switch is indicated by a dashed line, and the switching position of the switching lever of the automatic fan switch is indicated by a solid line) is l-1 and l
-It is different from 2, and when operating it, it feels strange and it interferes with the operation feeling. If an attempt was made to avoid this, switch boards would be required for the manual fan switch and the auto fan switch, which would be economically disadvantageous.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to provide a vehicle switch device in which the amplitude of swing of the switching lever at the lever slit remains almost constant even when the fan switch is replaced with a fan switch having a different number of switching steps. It is about providing.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a front panel having a lever slit portion from which a switching lever of a vehicle switch protrudes, and a lever slit provided on the back side of the front panel for switching by circular arc movement. a switch board that fixedly supports the switch provided with the switch lever, and the switch board is integrated with a lateral guide that allows the fan switch to move in the front-rear direction and restricts the lateral movement. Further, the switch board is provided with a plurality of front and rear stoppers for positioning and regulating the fan switch at a plurality of positions in the front and rear direction, and fixedly supports switches having different switching stages at different positions in the front and rear direction. Particularly, the swing width of the switching lever at the lever slit portion of the front panel is made substantially constant.

[Function] Since the present invention has the above-mentioned configuration, when a switch with a small number of switching stages is fixedly supported, the horizontal guide and the front and rear stoppers located at the rear of the plurality of front and rear stoppers are fixedly supported. When fixing and supporting a switch with a large number of switches, the switch can be fixed and supported at different positions in the front and back direction depending on the number of switching stages by using the horizontal guide and the front and rear stoppers located at the front of the plurality of front and rear stoppers. As a result, the swing width of the switching lever at the lever slit portion can be made almost constant.

[Embodiment] A vehicle switch device according to the present invention will be described below with reference to the drawings, taking a vehicle fan switch device as an example.

FIG. 1 is a schematic diagram of a vehicle fan switch device according to the present invention. In the figure, the same members as in FIG. 8, which is a plan view of a conventional vehicle fan switch device, are designated by the same reference numerals. Further, a fan switch is not shown to clarify the configuration of the device.

In the figure, the switch board 17 provided on the back side of the front panel 10 has four lateral guides that allow the fan switch to move in the front and back direction but restrict its movement in the lateral direction, similar to conventional vehicle fan switch devices. 18 are integrally molded.

However, in this embodiment, first front and rear stoppers 30, 31 and second front and rear stoppers 40,
41 is newly integrally molded on the switch board 17. The stoppers 30 and 40 are both stoppers that restrict the movement of the fan switch in the forward direction, that is, in the downward direction in the figure.The stopper 30 has an L-shaped cross section as shown in FIG. - It is a convex stopper with a cross-sectional shape that protrudes from the switch board in a direction perpendicular to the plane of the paper as shown in FIG. In addition, stoppers 31 and 32
Both are stoppers that restrict the movement of the fan switch in the rearward direction, that is, upward in the drawing. is shown in FIG.

As shown in FIGS. 3 and 4, the first front and back stopper 30 and the second front and rear stopper 40 are formed with a protrusion 30a and a protrusion 40a, respectively, at the portions that the fan switch comes into contact with. A cut groove 30b is also formed in the front and rear stopper 30.

Next, the operation of this embodiment will be explained using FIG. 5, FIG. 6, and FIG. 7.

FIG. 5 shows the switch board 17 shown in FIG.
A manual fan switch 14-1 that can be switched in three stages (Off-Lo-Hi) is shown fixedly supported. At this time, the manual fan switch 14
-1 is fixed by four lateral guides 18 that restrict movement in the lateral direction and first front and rear stoppers 30 and 31 that restrict movement in the front and rear directions.

Next, the manual fan switch 14-1
The auto mode has a fan switch i.e. Off
- When replacing the auto fan switch 14-2 with a four-stage switchable mode of Auto-Lo-Hi, first bend the stopper 30 in a direction perpendicular to the plane of the paper and cut it out.
A hole 50 is formed. Thereafter, the automatic fan switch 14-2 is fixedly supported on the switch board 17 at a position in front of the manual fan switch 14-1 by the four horizontal guides 18 and second front and rear stoppers 40, 41.

When fixing the fan switch, if the fan switch comes into contact with the protrusion 30a of the first front/rear stopper 30 and the protrusion 40a of the second front/rear stopper 40, the first front/rear stopper 30 and the second front/rear stopper 40 will slightly close to the front panel. Deflect to the 10 side. Then, due to their elastic force, both stoppers press the fan switch rearward and press it against the convex portions of the first front/rear stopper 31 and the second front/rear stopper 41. This allows the fan switch to be fixedly supported without wobbling.

As described above, in this embodiment, the first front and rear stoppers 30,
31 and second front and rear stoppers 40, 41 are newly integrally molded on the switch board 17, and a manual fan switch 14-1 that can be switched in 3 stages and an automatic fan switch 14-2 that can be switched in 4 stages are installed in the front and rear direction of the switch board 17. As shown in FIG. 7, the switching lever 12-1 of the manual fan switch 14-1 can be fixedly supported at different positions.
(shown with a dashed line) and auto fan switch 14
