Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combination switch for a vehicle, which is equipped with various switch mechanisms operated by the left-right swinging, up-down, swinging, and rotating operations of an operating lever.

Conventionally, this kind of combination switch for vehicles operates by swinging the control lever left and right to blink the turn signal lights, by swinging the control lever up and down to switch between main and dimer and passing, and by rotating the control knob at the tip of the lever. So, headlights, taillights, etc.
The most common type of device is one that operates on and off.

Among these three-way operating switches, the ones that are particularly problematic are those that operate by rotating a knob at the tip of the operating lever. There are two types that are installed at the bottom of the connected main body side support member, but both have their own problems.

In the former case, a wiring cord must be passed through the operating lever. For this reason, bending motion is applied to the cord during horizontal, vertical, and rotational operations near the fulcrum that holds the operating lever, and unless special consideration is taken, breakage will occur at this portion. Also, the workability of these assemblies is extremely poor.

On the other hand, if the switch part that forms the latter electric circuit is installed on the support member that forms the main body,
Because the operating knob and the switch part are separated from each other, and because they are moved in relation to each other during operations for other purposes in the horizontal and vertical directions, for example, a special spherical cam must be used. There were various problems such as difficulty in production technology such as maintaining the precision of parts and great difficulty in quality control.

In view of the above-mentioned problems, the present invention solves the conventional drawbacks, and provides a combination vehicle for a vehicle that is equipped with a lighting switch section that has an extremely simple structure and a small number of parts, which are not moved in relation to each other in operations for other purposes. The purpose is to provide a quick and easy switch.

Next, the operation of the vehicle combination switch according to the present invention having the above structure will be explained in detail with reference to the accompanying drawings.

In Figure 1, when the control lever 14 is moved to the left to the L position, the direction indicator switch 3 turns on the left direction indicator so that it flashes, and when the control lever 14 is operated to the right to the R position, the right direction indicator is turned on. It turns on like a blinking light. Further, at the neutral position N, it is in the OFF state.

Next, in the configuration in which the operation knob 15 is operated in the vertical direction, there are three positions, D, M, and P positions, as shown in FIG. Then the headlight pointing upwards will be lit. In addition, in the P position, the upward direction of the headlight can be turned on regardless of day or night, that is, the control lever 14 is automatically returned from the P position to the D position. Since it is configured with the inserted elastic contact member 11, it is easy to manipulate it back from the D position to the P position,
In addition, the headlight can alternately flash downward and upward at night, and can flash upward during the day. That is, main,
This serves as a dimmer switch and a passing switch.

Next, in the configuration in which the operating knob 15 is rotated, there are three positions, OFF, and OFF, as shown in FIGS. of
It constitutes a light switch that turns ON and OFF, and in the OFF position shown in the figure, the switch does not operate in any of the vertical operation positions of the main/damer changeover switch except for the P position, D, and M positions, i.e. The headlights are not turned on either downwards or upwards, and in this position the taillights, etc. are turned on and the headlights do not switch even in this position. In addition, the headlight is turned on at the position.

As described above, the electrical connection circuit of the lighting switch section 24, which engages with each operation direction and position to perform a switch action, is constructed as shown in FIG.

Next, the operation of the lighting switch section 24, which engages with each operating position to perform a switch operation as shown in FIG. 7, will be explained.

The other end of the operating rod 19 fixed to the operating lever shaft 13 engages with a guide plate 26 of the writing switch section 24 and a cam disc 27 in respective directions.

That is, when the operating knob 15 is swung in the vertical direction, both front and rear surfaces of the operating rod 19, which are swung together, fit between the protruding columns 26b of the guide plate 26, as shown in FIGS. 2 and 4. Since they are in contact with each other, the operating rod 19 presses the guide plate 26 in the front and back direction according to the swing positions P, D, and M, and the guide plate 26 is further engaged with the guide plate 26. Cam board 2
7 is horizontally slid forward and backward by a predetermined distance.

At this time, the other end of the push rod 29 that is in contact with the lower surface 27b of the cam disk 27 moves the movable contact pieces 31, 32, and 33 up and down in response to the mountain-like protrusions and valley-like depressions on the lower surface 27b of the cam disk 27. The contacts 31a, 32a and 33a of the movable contact pieces 31, 32 and 33 are moved to the fixed contacts 39a, 39b and 4 of the corresponding fixed contact plates 39 and 40.
It contacts or separates from 0a to turn on and off the main and dimer switching and passing switches.

Next, when the operating knob 15 is rotated, the operating rod 19 is rotated together as shown in FIGS. 5 and 6.
Both sides of the rotation direction are the two walls 27 of the cam disk 27.
Since it is fitted and abutted between a, the rotation position is
OFF, and depending on the position, the operating rod 19 presses the wall 27a of the cam disk 27. The pressed cam disk 27 is moved horizontally in the left-right direction with the wall 27a of the cam disk 27 being guided by the peripheral wall of the square hole 26a of the guide disk 26. At this time, the other end of the push rod 29 that is in contact with the lower surface 27b of the cam disk 27 immediately responds to the mountain-like protrusion or valley-like depression on the lower surface 27b of the cam disk 27, and the movable contact piece 3
1, 32 and 33 up and down, the contact point 31 of the movable contact pieces 31, 32 and 33
a, 32a and 33a are the corresponding fixed contact plates 3
9 and 40 fixed contacts 39a, 39b and 40a
of the light switch.
It has an ON and OFF action.

Furthermore, the operation of the main/damer changeover switch is performed by engaging the rotational operation position of the light switch, that is, when the rotational operation knob 15 of the light switch is in the OFF position, the main/damer changeover switch is activated. D which is the dammer switching operation position
The headlight is not turned on in any of the positions of and M. Also, when the light switch rotation knob 15 is in the OFF position, the headlights are not turned on in either the D or M positions, and only the taillights are turned on, similar to the OFF position. When the rotary operation knob 15 of the light switch is in the position, the headlight is turned on, and either one of the headlights is turned on depending on the upper or lower main or dimer switching operation position D or M.

In addition, only the passing operation position P is such that the upward direction of the headlight is always turned on regardless of whether the rotation operation knob 15 of the light switch is in the OFF position or not.

Furthermore, it goes without saying that the operating relationship between the main/damer changeover switch and the light switch is the same in the left and right rocking positions L and R, which cause the direction indicator light to blink.

The electrical connection circuit thus constructed according to each operating position of the lighting switch section 24 operates as shown in FIG.

In Fig. 7, 45 is a headlight.
46 is a tail light.

The combination switch for a vehicle according to the present invention having the above-mentioned structure and operation has the following effects.

(a) The cam disk that turns the movable contact point ON and OFF has mountain-like protrusions and valley-like depressions formed on a flat base, so the desired shape for the cam function can be freely formed. Easy to set and maintain dimensional accuracy.

(b) Since the main, dimer switching, passing switch, and light switch functions are configured with an extremely small number of parts and simple parts shapes, manufacturing costs are low.

(c) Since the lighting switch part constitutes an independent switch as a unit component, there is no possibility that the type of vehicle or other design changes of the combination switch on the main body, such as the length of the operating lever or the mounting angle, may be affected. It can be used universally, and standardization and integration are easy.
