As shown in FIGS. 1 to 3, the power window switch 1 is a four-door type power window switch mounted on the right front door, and includes a printed wiring board 10 as a wiring board and the printed wiring board 10. It is composed of a cover body 20 and a housing 30 to be housed, and a switch mechanism 40 provided on the cover body 20.

As shown in FIG. 4, the printed wiring board 10 has a pair of fixed manual contacts 11 for manually raising and lowering the windows of the respective doors, and a pair of vertically moving driver side front windows for automatic operation. The automatic fixed contact 12 and a predetermined printed wiring (not shown) are provided respectively, and as shown in FIG. 5, they are mounted on the housing 30 in a mounted state.

The cover body 20, as shown in FIG.
The printed wiring board 10 is mounted on the housing 30 so as to cover the printed wiring board 10.
As shown in FIG. 2, the switch mechanism 40 for raising and lowering the window of each door is provided at a position corresponding to each fixed contact 11, 12 of the printed wiring board 10.

As shown in FIGS. 1, 5 and 6, the switch mechanism 40 includes a set of driver switch mechanisms 40a for vertically operating the window glass of the right front door on the driver side, and three other switch mechanisms. The driver switch mechanism 40a and the passenger's seat switch mechanism 40b are each composed of three sets of passenger's seat switch mechanisms 40b for raising and lowering the window glass of the door. The driver switch mechanism 40a and the passenger's seat switch mechanism 40b respectively include an operating knob 41 and a mounting portion for mounting the operating knob 41. And 51.

The operation knob 41 is integrally attached to a knob main body 42, a plurality of operation rods 43 and one guide body 44 integrally formed with the knob main body 42, and a tip end portion of each of the operation rods 43. The printed wiring board 1
It is composed of a movable contact portion 45 that turns on the switch by contacting each of the fixed contacts 11 and 12 of 0.

The number of the operating rods 43 is different between the driver switch mechanism 40a and the passenger's seat switch mechanism 40b, and the operating knob 41 of the passenger's seat switch mechanism 40b has two operating rods for manual operation. In addition, the operation knob 41 of the driver switch mechanism 40a is provided with two operation rods 43 for automatic operation in addition to the two operation rods 43 for manual operation.

On the other hand, the mounting portion 51 has the cover 2
A support body 52, which is integrally formed with the knob body 0, supports the knob body 42 in a tiltable manner, and a tubular portion 53 and a slider 62 that receive a coil spring 61, which is a component of a moderation mechanism 60 described later, slides in the vertical direction. A pair of slide guides 54 that are freely supported, and holes 55 through which the operating rods 43 are inserted.
It is composed of

As shown in FIGS. 1 and 5, the support body 52 has a shaft portion 52a protruding outward, and in the state where the operating rod 43 is inserted into the hole 55, the knob body is formed. The operation knob 41 is tiltably supported by the support body 52 by fitting the shaft portion 52a into the fitting hole 42a formed in the shaft 42.

Further, as shown in FIG. 6, a slider 62, which is slidably supported in the vertical direction by the slide guide 54, is mounted on the upper end of the coil spring 61 inserted in the cylindrical portion 53. Due to the elastic biasing force of the coil spring 61, the tip end of the slider 62 is pressed against the sliding groove 44a formed in the guide body 44.

Therefore, when the operation knob 41 is tilted upward from the neutral state shown in FIG. 6, the slider 62 is relatively slid along the sliding groove 44a as shown in FIG. Moves downward against the elastic force of the coil spring 61. At this time, one operating rod 43 is pushed downward while tilting, and the movable contact portion 45 attached to the tip of the operating rod 43 has the movable contact portion 45 attached thereto.
The switch is turned on by contacting the corresponding fixed contact 11 of.

When the tilting operation of the operation knob 41 is released, the slider 62 is pushed up by the urging force of the coil spring 61, and the slider 62 and the guide member 4
The operation knob 41 is returned to the original position by the relative sliding movement with the sliding groove 44a of No. 4 in FIG. At this time, since the operating rod 43 integrally formed with the knob body 42 is lifted, the movable contact portion 45 attached to the tip of the operating rod 43 is separated from the fixed contact 11 which was in contact with the operating rod 43, and the switch is turned off. It

The slider 62, the coil spring 61, and the sliding groove 44a formed in the guide body 44 constitute the moderation mechanism 60 described above.
The expansion and contraction of the control knob 41 gives a feeling of operation to the operation knob 41.

The movable contact portion 45 is integrally attached to the lower end portion of the operating rod 43, and is made of an elastic member 45a made of a flexible elastic material having an insulating property, and a contact which is a lower surface of the elastic member 45a. The contact member 45b is made of a conductive material and fixed to the surface.

As the elastic member 45a, two types, a block body and a bellows body, are used. In the passenger seat switch mechanism 40b, the block body is used.
Both the block body and the bellows body are used in the driver switch mechanism 40a. That is, in the driver switch mechanism 40a, the elastic member 45a used by the operating rod 43 for manual operation and the operating rod 43 for automatic operation.
As shown in FIG. 5, the elastic member 45a of the operating rod 43 for manual operation is constituted by a bellows body, and the elastic member 45a of the operating rod 43 for automatic operation is constituted by a block body. Further, the elastic member 45a, which is a block body, has a contact surface that comes into contact with the fixed contact 11 inclining as the operating rod 43 tilts. It is tilted so as to have a predetermined inclination angle with respect to the axis of the operating rod 43 so as to come into contact with each other.

The material for forming the bellows body, which is the elastic member 45a, is a material such that the bellows portion is flexible and has a spring property, for example, a thermoplastic elastomer (vinyl chloride elastomer, olefin elastomer). ,
Styrene type elastomer, urethane type elastomer, polyamide type elastomer, polyester type elastomer, etc.) and silicone rubber are suitable.

In addition, in this embodiment, as described above, the movable contact portion 45 has the insulating elastic member 45.
However, the present invention is not limited to this. For example, if the elastic member itself is made of a conductive material, it is not necessary to provide a separate contact member. Absent. Further, in this embodiment, the elastic member 45a is divided into two types, that is, the block body and the bellows body, but all the elastic members 45a can be configured by the bellows body.

Further, the driver switch mechanism 40a
Adopts a double action system so that the window can be opened and closed both manually and automatically by tilting the operation knob. That is, the sliding groove 44 of the guide body 44 in the driver switch mechanism 40a.
8a, a step portion is formed in the middle thereof, and when the operation knob 41 is tilted to some extent as a first action (tilt operation in the first step), as shown in FIG. Only the movable contact portion 45 having the elastic member 45a of the bellows body is positioned on the step portion and first contacts the fixed contact for manual 11 to connect the fixed contact for manual 11, and the driver operates the operation knob 41. The window is raised and lowered only while the window is maintained.

From this state, when the operation knob 41 is further tilted as a second action (tilting operation in the second stage), as shown in FIG. 7B, the movable member having the elastic member 45a of the block body is moved. Even if the driver releases the tilting operation of the operation knob 41 at this point, the window is automatically closed until the contact portion 45 comes into contact with the automatic fixed contact 12 and the automatic fixed contact 12 is connected. Lifting operation is performed.

On the other hand, regarding the moderation mechanism 60 in the other passenger seat switch mechanism 40b, the sliding groove 44 of the guide body 44 is used.
Although the stepped portion is not formed in a, and the one-action system in which the fixed contact for manual 11 is connected by one action is configured, the tilting operation range of the operation knob 41 in the driver switch mechanism 40a and the other seat switch mechanism. Four
The tilting operation range of the operation knob 41 at 0b has the same configuration.

In the power window switch constructed as described above, the operating rod 43 is integrally molded with the operating knob 41,
Since the movable contact portion 45 is integrally attached to the tip of the operating rod 43 and the rubber contact switch which does not contribute much to the operation feeling of the operation knob 41 is omitted, the number of parts and the number of assembling steps are small. Becomes
Product cost can be reduced.

Further, since the contact surface of the elastic member 45a of the movable contact portion 45 which is a block body is inclined so as to have a predetermined inclination angle with respect to the axial center of the operating rod 43, it is fixed to the contact surface. The contact member 45b that is in contact with the fixed contact for manual 11 and the fixed contact for auto 12 surely come into contact with each other, and the reliability of the switch itself is improved.

Further, as described above, in the driver switch mechanism 40a adopting the double action system, the operating rod 43 for the manual operation is not provided with the elastic member 45a of the block body but the bellows excellent in the expansion and contraction performance. Since the elastic member 45a of the body is attached, there is no great difference in the operation feeling of the operation knob 41 between the first action and the second action, and the double action operation can be comfortably performed.

Further, since the switch mechanism 40 itself is provided with a moderation mechanism, a sufficient operation feeling can be obtained for the operation knob 41 without providing a rubber contact switch, and the entire power window switch is provided. It also has the advantage of being miniaturized.

[0037]

As described above, in the power window switch structure of the present invention, the operating rod is integrally molded with the operating knob, the movable contact portion is integrally attached to the tip of the operating rod, and the rubber contact switch is omitted. Since the configuration is adopted, the number of parts and the number of assembling steps are reduced, and the product cost can be reduced.

Further, providing a moderation mechanism for giving an operation feeling to the operation knob to the switch mechanism has an advantage that a sufficient operation feeling can be obtained without providing a rubber contact switch.
