Description

[Detailed Description of the Invention] The present invention relates to a switch mounting structure for mounting switches whose pressing operation directions are orthogonal to each other.

In the case where a vertical push type switch that is pushed in a direction perpendicular to the board surface and a horizontal push switch that is pushed in a direction along the board surface are attached to the board by screws, vertical push switches are used. The pressing operation force applied to the type switch and the horizontal push type switch is ultimately received by the screw. In this case, in a vertical push type switch, the operating force acts in the axial direction of the screw, so it is fine, but in a horizontal push type switch, the pushing force acts on the screw as a shearing force, and also Since a moment acts on it, it is disadvantageous in terms of strength. Therefore, regarding the horizontal push type switch,
It may be possible to increase the number of fixing screws, but
This increases the number of parts and requires more effort to assemble, leading to increased costs.

This idea was made in view of the above circumstances.
The purpose is to provide a switch mounting structure that can sufficiently receive the pressing force applied to the horizontal push type switch without increasing the number of fixing screws for the horizontal push type switch and the vertical push type switch. .

An embodiment in which the present invention is applied to an automobile switch device will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a horizontally elongated plastic board, which is fixed to a column tube, with a cylindrical part 2 formed in the center for passing the steering shaft. A light guide 3 made of translucent plastic and a cover 4 made of plastic covering the light guide 3 are arranged and fixed on the front surface. Reference numeral 5 denotes a holder which is inserted through a long hole 6 formed in the substrate 1 and supported rotatably in the direction of arrow A and the direction opposite to arrow A around a shaft portion 5a; The lever 7 is rotatably connected in the direction of arrow B and the direction opposite to arrow B through the lever 7, and the front end side of this lever 7 passes through a long hole 9 formed in the cover 4 and projects to the front side, and the rear end side of the lever 7 The side is the long hole 6
is inserted through it and protrudes from the back side of the board 1. Reference numeral 10 denotes a bracket whose shaft portion 10a is rotatably supported in a circular hole 11 formed in the substrate 1, and a lever 7 is provided at the rear end of the bracket 10 that protrudes from the back side of the substrate 1.
A pair of projecting pieces 10b are provided so as to sandwich the rear end portion, so that when the lever 7 is rotated in the direction of arrow B and the direction opposite to arrow B, the bracket 10
is rotated in the direction of arrow C and the direction opposite to arrow C. 1
Reference numeral 2 denotes a turn signal switch, which is fixed to the board 1 in a bridge-like manner so as to intersect with this at the rear side of the bracket 10, and although not shown inside, it moves in conjunction with the rotation of the bracket 10. The vehicle is provided with an operator for controlling the vehicle and a switch element that is operated by the operator to blink the right or left turn signal lamp. In Figure 3,
13 is a hazard switch that is a vertical push type switch,
This hazard switch 13 has mounting legs 13a and 13b on both sides, as shown in FIG.
One mounting leg 13a is inserted and held in a holding hole 14 formed in the side wall 1a on the back side of the board 1, and the other mounting leg 13b is protruded from the cover 4.
It is attached to the back side of the substrate 1 by tightening and fixing it with self-tapping screws 15 to a. 1
Reference numerals 6 and 17 denote a defogger switch and a parking switch, which are vertically pressed switches.As shown in FIG. Gas switch 16 side and parking switch 1
It has mounting legs 16a and 17a on the 7 side, respectively. Similar to the hazard switch 13, the defogger switch 16 and the parking switch 17 are
By inserting and holding one mounting leg 16a into a holding hole 19 formed in the side wall 1a of the board 1, and fixing the other mounting leg 17a to a protrusion 1b protruding from the board 1 using self-tapping screws 20, It is attached to the back side of the board 1. The hazard switch 13, the defogger switch 16, and the parking switch 17 installed in the above manner are provided with operating portions 13c, 16b, and 17b that protrude forward, and these operating portions 13c, 16b, and 17b are located on the cover 4 side. They are turned on and off by being pressed by push buttons 21 to 23 that are movable in a direction perpendicular to the plate surface of the substrate 1, that is, in a front-back direction. By the way, the hazard switch 13 and the defogger switch 16 are vertically opposed to each other with a predetermined interval in the installed state, and the defogger switch 16
The parking switch 17 and the parking switch 17 face each other with a predetermined distance from each other on the left and right sides due to their integrated structure. The area surrounded by these three switches 13, 16, and 17 is where a daymap switching switch 24, which is a horizontal push type switch, is arranged. The daymap passing switch 24 has a cylindrical portion 24a that protrudes laterally on the left side surface.
4a inserts and supports an operator 24b which is biased by a return spring (not shown), and mounting legs 24 are provided on both upper and lower sides (shown upside down in FIG. 3).
c and 24d. The daymap switching switch 24 is fitted between the hazard switch 13, the defogger switch 16, and the parking switch 17, and one mounting leg 24c is connected to the mounting leg 13b of the hazard switch 13 by the self-tapping screw 15. The other mounting leg 24d is attached to a protrusion 4b protruding from the cover 4.
It is attached by tightening together with the connecting portion 18 between the defogger and parking switches 16 and 17 using self-tapping screws 25. In this installed state, the daymap switching switch 24 connects the upper half of the right side to the defogger switch 1.
6, the lower part is brought into contact with a rib 13d protruding from the lower surface of the hazard switch 13, and the upper half of the left side is brought into contact with the parking switch 1.
7, attach the right half of the upper side to the hazard switch 13
In addition, the cylindrical portions 24a are brought into contact with the parking switch 17, respectively. An operating portion 24b protruding from the cylindrical portion 24a is in contact with the rear end portion of the holder 5. Although not shown in the dimmer switching switch 24, there is a passing switch element that closes when the operator 24b is pushed in, and a high beam switch element that closes when the operator 24b is pushed in.
A dimming switch element is provided that alternately energizes the low beam.

In the above configuration, when the lever 7 is rotated in the direction of arrow A, the holder 5 rotates together with the lever 7 in the same direction, and the operator 24b of the daymap switching switch 24 is rotated by the spring force of the return spring. and push it in the direction along the board surface of the substrate 1, that is, to the right. For this reason, the dimmer switching switch 24 is subjected to a strong pressing force to the right, but since some of this pressing force is received by the hazard switch 13 and the defogger switch 16, the dimmer switching switch 24 is actually
The pressing force that you bear will not be so large. Therefore, daymap passing switch 2
4 is ultimately applied not only to the self-tapping screws that attach the daymap switching switch 24 but also to the self-tapping screws that attach the hazard switch 13 and the defogger switch 16. As a result, even though force in the shearing direction (pressing force of the dimmer pushing switch 24) and moment act on each self-tapping screw, each self-tapping screw is The shearing force and moment to be borne are not so large, and there is no need to increase the number of self-tapping screws.

By the way, since a part of the pressing force applied to the daymap switching switch 24 also acts on the hazard switch 13 and the defogger switch 16, the self-tapping screws that attach these hazard switch 13 and the defogger switch 16 are The question may arise as to whether there is a need to increase the number of . However, the thickness and number of self-tapping screws that attach the hazard switch 13 and the defogger switch 16 are set with a so-called safety factor in mind.
Hazard switch 13 and defogger switch 1
It can sufficiently withstand even if a force somewhat larger than the pressing operation force applied to 6 is applied. Therefore, even if part of the pressing force applied to the dimmer switching switch 24 acts on the hazard switch 13 and the defogger switch 16, there is no need to increase the thickness or number of self-tapping screws. .

As is clear from the above description, the present invention has a structure in which a horizontally pressing type switch is fitted between a plurality of vertically pressing type switches and is installed so that the side surface is in contact with the vertically pressing type switch. The applied pressing force can be distributed and received by the vertical push type switch, so there is no need to increase the number of screws for fixing the horizontal push type switch and the vertical push type switch, reducing the number of parts and the number of assembly steps. By preventing the increase in
This has an excellent effect of reducing costs.
