Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lever switch for an automobile in which two or more types of switch devices are operated by different operations of one operating lever.

Conventionally, when an operating lever in a car is tilted in the vertical direction, a direction indicator switch is operated, and when the operating lever is tilted forward or backward, a daylight changeover switch is operated, and the operating lever is further provided with a rotation knob. There is a lever switch in which a lighting switch can be operated by rotating a lever rotation knob around an axis.

Among these lever switches, those in which the lighting switch is provided within the rotary knob and the operating lever has a single shaft structure have the disadvantage that the rotary knob becomes large and wiring for the writing switch becomes difficult.

On the other hand, the writing switch is removed from inside the rotary knob by inserting the rotary shaft rotated by the rotary knob into the operating lever and making the operating lever have a double shaft structure, which has the above disadvantages. However, it has the disadvantage that the structure of the lever becomes complicated because it has a double shaft shape.

The present invention was made to eliminate the above drawbacks,
The purpose of this is to operate a first switch device by a tilting operation of one operating lever about its fulcrum axis, and by rotating the operating lever itself around its axis, the above-mentioned tilting operation can be performed. To provide a lever switch for an automobile, which can simplify the structure of the lever by allowing the second switch device to be operated independently of the second switch device, and also facilitate wiring processing for the second switch device.

The cylindrical portion 16 of the second actuating member 15 is inserted into the cylindrical portion 10 of the first actuating member 9 so as to be rotatably inserted into the other end of the operating lever 13. so that it can be rotated around the axis together with the operating lever 13.

Reference numeral 18 denotes a wiper control switch corresponding to a second switch device, which has a switch case 19 fixed to the support frame 1, and has a fixed contact block 20 and a movable contact block 21 (moving member) inside the switch case 19. The movable contact block 21 can be slid in the front and back direction with respect to the plane of the paper in FIG. A movable contact group 23 is provided.

An opening 24 is provided on the upper surface of the switch case 19 in FIG.
At the same time, a locking groove 25 is formed approximately in the middle of the upper surface of the movable contact block 21, as shown in FIG. The tips of the 15 second operating projections 17 are positioned through the openings 24 of the switch case 19 into the locking grooves 25 (the operating projections 17 serve as retaining means) of the movable contact block 21.

Reference numeral 26 denotes a Dimmer changeover switch corresponding to the first switch device, which includes a pair of leaf spring type movable contact pieces 28 and 29 whose base ends are supported by the support member 27, and a fixed contact piece that is selectively contacted by these movable contact pieces 28 and 29. 30, 31 and a switch cover 32 surrounding them, and the tip of the first actuating protrusion 11 of the first actuating member 9 is located between the pair of movable contact pieces 28, 29.

33 is a washer button provided on the end surface of the grip portion 14 of the operating lever 13; 34 is a washer switch provided in the grip portion 14; when the washer button 33 is pressed against the compression spring 35, the washer switch 3 is activated.

37 is a moderation mechanism, and a cam surface 38 formed on the rotating member 3
The operating lever 13 is selectively held at the low beam position HL and the high beam position mark, and the passing display position It has the function of returning from the low beam position to the HL direction.

Based on the same principle as described above, a moderation mechanism 37a is provided between both the first actuating member 9 and the second actuating member 15 to maintain the rotational position around the axis of the operating lever 13.

In the above configuration, the first operating protrusion 11 is located on the rotation center line A of the rotating member 3 when the operating lever 13 is set to the low beam position HL, and the second operating protrusion 1
7 is the rotation center line A of the rotating member 3 when the operating lever 13 is set to rotate around its axis to the wiper off position OFF (see Fig. 5) and the low beam position is set to the north.
It is preset to be located at the top.

In addition, the operating lever 13 is moved to the left turn instruction position TL and the neutral position TN.
It also has a moderation mechanism that holds it at the right turn instruction position TR,
This is omitted from illustration.

In addition, a wiper control switch 18, a daylight changeover switch 2
The circuits controlled by the washer switch 6 and the washer switch 34 may be well-known circuits, and are therefore not shown.

Next, the operation of the above configuration will be explained.

Move the operating lever 13 to the left turn instruction position TL and the neutral position TN.
When the tilting operation is performed between the right turn instruction position TR and the right turn instruction position TR, the first actuating member 9, the second actuating member 15, and the rotating member 3 rotate together with the operating lever 13 about the hollow shaft 4, but the direction Only the instruction switch is operated.

On the other hand, when the operating lever 13 is tilted between the bi-beam positions around the pin 12 at any of the left turn instruction position TL, neutral position TN, and right turn instruction position TR, the first operating member 9 The first operating protrusion 11 rotates to the position shown by the two-dot chain line on the right in FIG.
The movable contact 29 in 6 is pressed in the direction of arrow 40 and is separated from the fixed contact piece 31, and the movable contact piece 28 moves away from the fixed contact piece 31.
When the headlamp is brought into the bi-beam state by contact with Repeatedly moving the movable contact piece 28 to the position shown by arrow 4.
By being pressed in one direction and repeatedly touching the fixed contact piece 30, the headlamp is set to intermittent bi-beam mode to display a passing display, and the operating lever 13 is moved to the low beam position HL.
When the first actuating projection 11 is in the position shown by the solid line in FIG. 2, the movable contact piece 29 comes into contact with the fixed contact piece 31, so that the headlamp is set to a low beam.

Next, grip the operating lever 13 by its grip part 14,
In Figure 5, wiper off position OFF, intermittent wiping position IN
T, low speed wiping position.

When the second actuating member 15 is rotated about the axis between the high-speed wiping position H1 and the high-speed wiping position H1, the second actuating member 15 is rotated about the longitudinal axis of the operating lever 13 integrally with the operating lever 13. The operating protrusion 17 is engaged with the inner surface of the locking groove 25 of the movable contact block 21 in the wiper control switch 18, and the movable contact block 21 is moved to the operating lever 13.
to switch the contact relationship between the fixed contact group 2.2 and the movable contact group 23 by moving it in a direction according to the direction of rotation around the axis of the contact group 2.2,
It controls a wiper control electronic circuit (not shown).

That is, the wiper operation lever 13 is in the low speed wiping position.

When set to wiping operation at low speed, high speed wiping position H1
When set to INT, the wiping operation is performed at high speed, and when set to the intermittent wiping position INT, the wiping operation is performed after a certain pause time.

In the above, the rotation of the operating lever 13 around the axis is performed within the cylindrical portion 10 of the first actuating member 9, and the rotational displacement is not transmitted to the first actuating member 9, so that the dimmer changeover switch 26 is disabled. Careless manipulation is prevented.

Also, when the operating lever 13 is tilted between the bi-beam position H-U, the low beam position north and the passing display position set, the second actuating protrusion 17 of the second actuating member 15 locks the movable contact block 21. Since the wiper control switch 18 is only moved parallel to the inner surface of the groove 25 and no displacement is transmitted to the movable contact block 21, there is no possibility that the wiper control switch 18 will be operated due to the passing display and daylight switching operation by the operating lever 13.

In the above operation, when the operating lever 13 is operated to either the bi-beam position HLJ or the passing display position HP, the first operating protrusion 11 moves away from the center of the hollow shaft 4, that is, the rotation center line A of the rotation member 3. In Fig. 2, there is a shift in the left and right direction,
In this state, if the operating lever 13 is further tilted to positions TL, TN, and TR for left turn instruction, neutral, and right turn instruction, the tip of the operating protrusion 11 will move from the two-dot chain line position in FIG. Displace up and down.

However, since the actuating projection 11 is located near the center of the hollow shaft 4, these displacements are extremely small and do not reach the level that causes the dimmer changeover switch 26 to operate undesirably.

Similarly, the first operating protrusion 17 is located at the center of rotation of the rotating member 3 when the operating lever 13 is at a rotational position around the axis other than the wiper off position OFF, and when it is at a tilted position other than the low beam position HL. deviates from the line A, and therefore, when the operation lever 13 is operated in the direction indicating operation direction (vertical direction in FIG. 2), the movable contact block 21 may be displaced. Since it is positioned near the rotation center line of the member 3, the amount of deviation from the rotation center line is extremely small, and there is no risk of undesired operation of the wiper control switch 18.

Therefore, according to the above configuration, the direction indicating switch is operated by tilting the single operation lever 1.3 in the vertical direction, and the dimmer changeover switch 26 is operated by tilting the single operating lever 1.3 in the front and rear directions. However, in the present invention, the wiper control switch 18 can be operated by rotating around the axis of the single operating lever 13 itself, without providing a rotating knob for switch operation on the operating lever.
Therefore, the operating lever 13 has a single-shaft structure instead of a double-shaft structure, which simplifies the configuration.Moreover, it can be used as a switch compatible with a conventional rotary knob switch. Since the wiper control switch 18 can be installed near the steering shaft without being installed on the operation lever 13 side, wiring for the wiper control switch 18, which has a large number of switches, is facilitated, similar to the conventional dual-axis structure operation lever. It is something.

It goes without saying that the functions of the switches operated by the operating lever 13 in the present invention are not limited to those of the above embodiments.

As described above, the present invention can provide a lever switch for an automobile that has a simple structure and easy wiring and processing.
