Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mounting structure for attaching a lever switch such as an auto drive switch (constant speed driving device) to a horn switch cover located in the center of a steering wheel of an automobile. .

Prior Art FIG. 3 shows a conventional example. In the figure, 1
4 is a boss that connects the steering wheel and the steering mechanism; 10 is a bowl-shaped horn switch cover located around the boss 14 and stores the horn switch and other parts therein; 11 is a lever switch; Switch 11 is switch case 11
a and an operating lever 11b.

Horn switch cover 10 and lever switch 1
1, a window 13 through which the lever switch 11 can pass is provided in the side wall 10a of the horn switch cover 10, as shown in the figure. The lever switch 11 has an operating lever 1 on the window 13.
1b, the switch case 11a is attached to the bottom wall 10b of the horn switch cover 10 using fixing means such as screws. Therefore, after installing the lever switch 11, the window 1
3 and the switch lever 11, and in order to close this space, a lid 12 having a lever insertion hole 14 in its center is fitted into the window 13.

Problem to be Solved by the Invention However, since the lid 12 is fitted into the window 13 after the lever switch is attached, the lid 12 is
The lever insertion hole 14 provided in the operating lever 11b
must be large enough to pass through. By the way, the lever neck 11d of the operating lever 11b is formed smaller than the lever neck 11c. Therefore, the lid 12 is replaced by the window 13.
Even after fitting into the lever insertion hole 14,
Lever neck 11d with a smaller cross section than the hole 14
A space will be formed between them. In other words, a visual problem arises in that the inside of the horn switch cover is visible to the driver, especially when the horn switch cover is installed, and the horn switch cover cannot be seen from the space above and below the switch lever (in the direction perpendicular to the drawing sheet in Figure 3). The problem is that you can see inside.

The present invention has been devised in view of the above-mentioned conventional technical problems and to effectively solve them.

The objective is therefore to solve the visual problem caused by the space created by the lever neck and the lid that fits into the window in the side wall of the horn switch cover, i.e. to provide the driver with a clear view of the horn switch cover. To provide a lever switch mounting structure in which the inside of the lever switch cannot be seen.

Means for Solving the Problems and Actions/Effects The steering wheel switch mounting structure according to the present invention is configured as follows in order to solve the conventional technical problems and achieve the purpose.

That is, the structure is for attaching a lever switch to a synthetic resin horn switch cover located in the center of the steering wheel, and the horn switch cover has a lever switch mounting window at a predetermined position. A lid having a lever insertion hole for the lever switch is fitted into the lever switch, and the lever switch includes a switch case fixed within the horn switch cover, and a switch case that protrudes swingably from the case and has a lever insertion hole in the lid. The horn switch cover has an operating lever that is guided outward through the horn switch cover, and further, the horn switch cover is formed integrally with the cover body and closes the lever insertion hole inside the window along the inner surface of the lid. It has a flexible thin plate-like shielding piece that extends as far as possible and has a notch through which the operating lever of the lever switch is inserted.

In the above configuration, the thin plate-like shielding piece formed inside the horn switch cover bends when the lever switch is installed so as not to interfere with the installation work of the switch case. Further, after being attached, the thin plate-like shielding piece returns to its natural state. Further, even when the lever is operated after being attached, the shielding piece bends following the lever, and there is no problem in operating the lever.

According to the above configuration, the space formed by the window provided in the horn switch cover and the operating lever,
Since the thin plate-shaped shielding piece closes the horn switch cover, it is possible to prevent a visual defect in which the inside of the horn switch cover is visible to the driver.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view showing a lever switch mounting structure according to an embodiment of the present invention. As in the prior art, a window 4 is formed in the side wall 1a of the horn switch cover 1 which is located around the boss 7 and houses the horn switch and other parts therein. The window 4
A lever switch 2 can be inserted therethrough, and the lever switch 2 is composed of a switch case 2a and an operating lever 2b. The operating lever 2b
is swingable only within the range and angle indicated by θ in the figure. After the switch case 2a is attached to the bottom wall 1b of the horn switch cover 1, the lid 3 is fitted onto the window 4.
is a hole 6 through which the operating lever 2b can be inserted as in the conventional case.
It has the following. Therefore, a space exists between the hole 6 and the lever neck 2d.

Here, a thin plate-shaped shielding piece 5 is integrally formed inside the horn switch cover so as to extend in substantially the same direction as the axial direction of the steering wheel center shaft 8 and along the inner surface of the lid 3. The thin plate-like shielding piece 5
The shape is a bifurcated shape as shown by the broken line in FIG. 2, and the inner width A of the bifurcated portions 5a and 5b is slightly larger than the width B of the lever neck 2d. Furthermore, the thin plate-like shielding piece 5
is formed using a flexible soft resin such as polyurethane elastic material.

In the above configuration, when installing the lever switch 2, the bifurcated portion 5 of the thin plate-like shielding piece 5 is
Since a and 5b are mutually flexible, they do not interfere with the installation work. Further, after the installation is completed, the shielding piece 5 returns to its natural state, that is, the state shown in FIG. 1. As mentioned above, the inner width A of the bifurcated part is the width B of the lever neck 2d.
Since the lever switch 2 is slightly larger than the lever switch 2, it does not interfere with the operation of the operating lever 2b even after the lever switch 2 is installed.

With the above configuration, the spaces 6a and 6b located on the left and right sides of the operating lever in FIG. 2 are among the spaces formed by the operating lever penetration hole 6 provided at approximately the center of the lid 3 and the lever neck 2d. The bifurcated portions 5a and 5b can respectively close the spaces located above and below the operating lever when assembled. Therefore, visual problems such as the inside of the horn switch being visible from above and below the lever switch can be solved.
