Description

[Detailed Description of the Invention] The present invention relates to an illuminated switch mechanism for a vehicle.

Conventionally, in an illuminated switch mechanism for a vehicle, for example, as shown in FIG. A configuration in which the illumination lens 2a' is illuminated at the operating position is known, but the size of the illumination lens 2a' is often limited to one side of the upper surface of the operation knob 2'.
As a result, the area of the illumination section is relatively small, and the illumination intensity is often insufficient. In this structure, in which the operating rod 2b' is integrally formed with the lower surface of the central part of the operating knob 2', protruding downward,
Even if the area of the illumination lens 2a' was enlarged, it was difficult to uniformly illuminate the entire surface due to the shadow caused by the operating rod 2b'.

Furthermore, since the area of the illumination lens 2a' is relatively small, the illumination intensity will be insufficient unless the capacity of the internal illumination lamp 3' is increased, and depending on the surrounding environment, visibility may become unclear. It was triggered. Furthermore, increasing the capacity of the illumination lamp 3' has disadvantages such as increased power consumption, increased installation space, and increased temperature due to heat generation, resulting in an increase in the size of the entire switch structure.

The present invention was devised in order to eliminate the above-mentioned drawbacks, namely, there is no protrusion such as an operating rod on the lower surface of the central part of the operating knob, so that the light from the illumination lamp can illuminate almost the entire surface. This makes it possible to increase the light-emitting area of the lighting lens, making the brightness of the lighting more effective, and making it possible to provide lighting with a predetermined brightness even with a relatively small capacity lighting lamp. It is an object of the present invention to provide an illuminated switch mechanism for a vehicle that consumes less power and is easily miniaturized.

Preferred embodiments of the illuminated switch mechanism for vehicles according to the present invention are shown below in Figs. 2, 3, 4, and 5.
This will be explained in detail based on the figures.

On the illumination lens 2, characters or pictograms or the like can be displayed according to the operating function, if desired.

Also, side walls 2c on both sides of the central part of the operation knob 2
and 2e, support shafts 2b are formed integrally protruding at symmetrical positions with respect to each other. Furthermore, the side wall 2c having one of the support shafts 2b is extended further downward to a predetermined position, and a moderation crest 2d is formed on the lower end surface thereof. The moderation crest 2d corresponds to the elastic member 7 inserted into the hole 1f bored in the partition surface 1c on one side of the case 1, and forms a moderation device.

Furthermore, near the inner side of the side wall 2e having the other support shaft 2b, an operating rod 2f inserted into the case 1 along the inner wall surface of the wall 1d forming the opening 1e of the case 1 is provided downward. It is integrally formed and protrudes from the top. The tip of the operating rod 2f forms a small disc portion 2g forming an arc in the swinging direction of the operating knob 2, and the tip forms a groove 3c of the movable member 3 inserted in the case 1 so as to be swingable in a predetermined direction. is engaged with. 3 is a movable member. The movable member 3 has a protrusion 3b formed on one side of the upper surface 3a, that is, corresponding to the operating rod 2f of the operating knob 2, and a groove 3c is formed at a predetermined position of the protrusion 3b. A small disk portion 2g at the tip of the operating rod 2f of the operating knob 2 is placed in the groove 3c.
It is loosely fitted and locked. That is, the small disc 2g of the operating rod 2f swings integrally with the swinging operation of the operating knob 2.
The movable member 3 is slidably moved by a predetermined distance. A movable contact piece 4 is fixed to the lower surface of the movable member 3 in correspondence with a fixed contact 6 of the base plate 5 to form a predetermined electric circuit. 4 is a movable contact piece. The movable contact piece 4 is formed of a plurality of comb-shaped contact pieces 4a made of an elastic thin plate spring material, for example, in accordance with a desired electric circuit, and a contact point 4b attached to the free end on the tip side is connected to the base plate 5 side. The movable member 3 is fixed to the lower surface of the movable member 3, and is urged to be brought into contact with or separated from the fixed contact 6 by a predetermined pressure.
5 is the foundation. The base plate 5 has a plurality of fixed contacts 6 embedded therein for forming a predetermined electric circuit in correspondence with the movable contact pieces 4, and is attached to the opening 1b of the lower end surface of the case 1. 6 is a fixed contact.
One end of the fixed contact 6 is arranged on the upper surface of the inner surface of the base 5 in correspondence with the movable contact piece 4 to form a predetermined electric circuit, and the other end is provided with a connecting terminal on the lower surface of the base 5 on the outside. 6a is integrally formed and buried. 7 is an elastic contact member. For example, a steel ball or the like may be used as the elastic contact member 7, which is inserted into the hole 1f of the case 1 together with the spring 8, and engaged with the moderation ridge 2d formed on the lower end surface of the side wall 2c of the operation knob 2. They work together to form a moderation device. 9 is an illumination lamp.

The illumination lamp 9 is disposed on the inner surface of the central part of the side wall of the case 1 in the direction in which the operating knob 2 is swung, as shown in FIGS. 3 and 4, for example. It is attached so that the entire surface of the illumination lens 2a provided on the upper surface can be illuminated.
