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 horizontal and vertical swinging of an operating lever and the rotation of an operating knob.

Conventionally, this type of vehicle combination switch has a first switch that operates a direction indicator light switch by swinging the control lever left and right, and a second switch that operates a main daylight passing switch by swinging the control lever up and down. The most common configuration is to have a second switch and a third switch that turns on and off the headlights, taillights, etc. by rotating the operating knob at the tip of the lever.

Among these three-way operation switches, the one that is particularly problematic is the one that operates by rotating the operation knob at the tip of the operation lever, and the third switch part that forms the electric circuit is housed inside the operation knob. There are two types: one in which the control lever is connected to the main body support member, and the other in which the second switch is attached to the lower part of the support member on the main body side to which the operating lever is connected, but both of them have their own problems.

That is, in the former case, since the wiring cord must be passed through the operating lever, there are restrictions on the diameter of the cord, and it is not possible to turn a large load capacity on and off, so this must be done via a relay, etc. It was impossible. Further, near the cord outlet near the fulcrum that holds the operating lever, bending motion is applied to the cord during left/right or up/down operations, and unless special consideration is taken, breakage will occur at this portion. Also,
The workability of these assemblies is also extremely poor.

On the other hand, in the latter case, where the switch part that forms the electric circuit is installed at the bottom of the support member that forms the main body, the operation knob and the switch part are separated, and the left and right rocking operation and up and down rocking operation are difficult. For example, a special spherical cam must be used, or a cam disk that is driven by the rotation operation and a cam disk that is driven by the vertical swing operation must be used. and independently, that is, 2
It had one operating rod and two cam discs, and the switch was operated by a separate cam disc in each direction of operation.

For this reason, it has the drawbacks that it is difficult to manufacture such as maintaining the accuracy of parts, or that the number of component parts increases and the structure becomes complicated.

The present invention solves the above problems, and uses one operating rod and one cam disk to operate each switch by receiving the drive of vertical swing operation and rotation operation, and further operates by left and right swing operation. The turn signal light switch is also integrated into one case to create a unit configuration.

This is an automatic return spring for automatically returning the movable member 7 to the original neutral position N when the engagement is released.

Next, the effect will be explained.

In FIG. 1, when the operating lever 14 is operated to the left position L, the movable contact plate 43 of the direction indicator light switch 3 moves to the left due to the swinging of the movable member 7, and comes into contact with the fixed contacts 26 and 27. Then, when the operating lever 14 is operated to the right to the R position, the movable contact plate 43 similarly moves to the right and comes into contact with the fixed contacts 26 and 28, forming the respective desired electric circuits and turning on the direction indicator light. flashing. In addition, in order to operate the direction indicator light switch 3, the operating lever 1 is
4 is operated to position L or position R as described above, it is fixed to the operating lever shaft 13 and the cam disc 23
The position of the spherical portion 18b at the tip that engages with the control lever 14 is set so that it corresponds to approximately right below the center of the swing center position of the control lever 14 in each vertical position of the control lever 14 and in each rotational position of the control knob 15. Because of this consideration, the cam disk 23 hardly changes, and thus the cam disk 23 is not driven by the operation of the direction indicator light switch 3, and maintains its initial position.

Next, in a configuration in which the operating lever 14 is operated in the vertical direction, as shown in FIG.
When the operating lever 14 is in the illustrated position D, the downward direction of the headlight is lit, and in the position M, the upward direction of the headlight is lit. In addition, in position P, 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 position P to position D by adjusting the moderation ridge 7e, which forms the moderation device of the movable member 7, and the lever guide 12. By being configured with the inserted elastic contact member 17, it is easy to repeatedly operate from position D to position P, and at night, the headlight can flash downward and upward alternately, and during the day, It is possible to make the headlight blink upwards. In other words, it serves as a main timer switching and passing switch.

Next, in the configuration in which the operation knob 15 is rotated, the fifth
As shown in the figure and Fig. 6, there are three positions: OFF,
It constitutes a light switch that turns ON and OFF, and in the OFF position, the switch does not operate in any of the vertical operation positions of the main dimer changeover switch except for position P, D, and M.
That is, neither the downward nor the upward headlights are turned on, and in this position, the taillight etc. are turned on, and the headlight switch is not activated in this position as well.

Also, the headlights are turned on at certain positions.

As described above, the electrical connection circuit of the lighting switch 4, which is operated by the engagement between the operating direction and position of the operating lever 14 in the up and down direction and the rotational operation of the operating knob 15, is constructed as shown in FIG. .

Next, as shown in FIG. 7, the operation of the lighting switch 4, which engages with each operating position to perform a switch operation, will be explained.

A spherical portion 18b at the tip of the operating rod 18 fixed to the operating lever shaft 13 engages with the cam disc 23.
That is, when the operation lever 14 or the operation knob 15 is swung in the vertical direction, the operation rod 18 that is swung together as shown in FIGS.
The cam disc 23 engaged with the cam disc 8 is guided by a guide plate 24 in the front and back direction by a predetermined distance and is caused to slide horizontally together. At this time, cam board 23
Push rods 30a, 3 in contact with the lower surface of
The tips of 1a and 32a move up and down in response to the mountain-like projections 23d and valley-like depressions 23e, movable the movable contact pieces 30, 31, and 32, and come into contact with the corresponding fixed contact plates 33 and 34, Alternatively, it can be opened to perform the switching of the main dimer and the ON/OFF action of the passing switch.

Next, when the operating knob 15 is rotated, the operating rod 18 is rotated as shown in FIGS. 5 and 6.
The cam disk 23 is horizontally slid in the left-right direction by a predetermined distance. At this time, cam board 23
Push rods 30a, 3 in contact with the lower surface of
1a and 32a are mountain-shaped protrusions of the cam disk 23, 23d
Alternatively, in response to the valley-shaped depression 23e, the movable contact pieces 30, 31, 32 are moved up and down in the same manner as described above to make contact with or separate from the fixed contact plates 33, 34, thereby turning the light switch ON/OFF. It is something that works.

Then, turn on the contacts of movable contact pieces 30 to 32,
Since the cam disk 23 that turns off the cam disk 23 has a mountain-like protrusion 23d and a valley-like depression 23e formed on the flat base 25, the desired shape for the cam function can be freely set, and dimensional accuracy can also be maintained. It's easy to do.

Furthermore, the operation of the changeover switch of the main daimer is performed as described above by engaging the rotational operation position of the light switch, but only the operation to position P, which forms the passing switch, is performed by the light switch. The position of the rotation operation knob 15
The upward headlight is always lit regardless of whether it is OFF or not.

Furthermore, it goes without saying that the operating relationship between the main daymer passing switch and the light switch is the same at the left and right rocking position L or R where the direction indicator light is blinked.

The electrical connection circuit thus constructed according to each operating position of the lighting switch 4 operates as shown in FIG.

In FIG. 7, the terminal 38 is connected to the fixed contact plate 33.
The terminal 39 is connected to the movable contact piece 32, the terminal 40 is connected to the fixed contact plate 34, the terminal 41 is connected to the movable contact piece 31, and the terminal 42 is connected to the movable contact piece 30, respectively.
46 is a headlight, and 47 is a taillight.

Note that the configuration of the electrical connection circuit is one example, and it can be easily changed to other desired electrical connection circuits by changing the configuration of the protrusion 23d and depression 23e on the lower surface of the cam disk 23. .

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

(a) The lighting switch, which functions as both a main daymer passing switch and a light switch, is a mechanism in which one operating rod drives one cam disk, so the number of component parts is extremely small and the part shape is simple. Since it is composed of , manufacturing costs are low.

(b) Since three switches operated by one operating lever are installed on the same base in one case, it is compact and can be easily attached to and detached from the support member that makes up the main body, making it easy to assemble. Furthermore, it can be used universally regardless of the type of vehicle, and standardization and integration are easy.
