Description

  The present invention relates to a vehicular switch device that is fixed to a vehicle and can turn on and off a predetermined switch by a pressing operation.

  For example, a switch body which is disposed on a vehicle instrument panel or the like and is fixed at a predetermined position on a vehicle panel or the like as a vehicle switch device for turning on and off a predetermined electrical component such as a fog lamp which is provided on the vehicle by a pressing operation. And a roller member that is slidable within the switch body and turns on and off a predetermined switch, and a button portion that covers one end of the roller member and slides the roller member by an operator's pressing operation.

  That is, when the button member is pressed to bring the roller member into the immersive state with respect to the switch body, a predetermined switch is turned on, and when the pressing operation is performed again, the roller member is protruded and the switch is turned off. On the surface of the button part, a transmissive part (symbol) that can be lit and displayed regardless of whether the predetermined switch is on or off and the switch is on so that a symbol indicating the type of switch can be seen at night. In order to make it visible, it has been provided that a transmissive portion (telltail) that can be lit and displayed only when the roller member is in an immersive state is formed.

  In such a conventional switch device for a vehicle, in order to selectively light and display symbols and tell tales, two light sources are provided to turn on each of them, and the roller member is in a protruding state with respect to the switch body. When is off, only the light source that illuminates the symbol emits light, and when the roller member is immersed in the switch body and the switch is on, the two light sources illuminate the symbol and tell tale. It is configured to light both. Thus, the symbol is always lit and displayed at least at night, and when the predetermined switch is turned on, the telltale is also lit and displayed. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the above conventional vehicle switch device, since the symbol and the tell tale need to be selectively lit and displayed, two light sources are provided in the switch body, so that when the switch is off (ie, the symbol The light from the light source that illuminates the symbol diffuses and wraps around in the roller member, and the tell tale appears to be lit (hereinafter this phenomenon is called pseudo-lighting). there were.

  In order to solve such a problem, a wall that separates a light path from one light source to the symbol and a light path from the other light source to the tell tale is provided in the roller member, and the inside of the roller member including the wall is provided. Although it is conceivable to use black or the like having a high light absorption rate, even in that case, there are the following problems. That is, when the wall and the roller member are black or the like, which has a high light absorption rate, the light emitted from the light source is significantly attenuated, the amount of light reaching the button portion is reduced, and the symbol lighting display (particularly luminance) is achieved. There was a risk of becoming insufficient.

  However, in order to display the symbols sufficiently, it is necessary to increase the amount of light from the light source. For this purpose, it is necessary to make the light source itself large or consume a large amount of power. As a result, the switch device becomes larger, or it becomes necessary to supply larger electric power.

  The present invention has been made in view of such circumstances, and can perform sufficient lighting display without increasing the light emission amount of the light source, and can reliably suppress pseudo lighting. Is to provide.

  The invention according to claim 1 is a switch body that can be fixed at a predetermined position of a vehicle, a roller member that is slidable between an on position and an off position of the predetermined switch in the switch body, and the roller An operation unit that covers one end side of the member and slides the roller member by an operator's pressing operation, a first light source that lights both when the roller member is in the off position and the on position, and the roller member is on A second light source that is turned on only when in position, a first transmission unit that is formed at a position facing the first light source in the operation unit, and that transmits light emitted from the first light source; A second transmissive portion that is formed at a position facing the second light source and transmits light emitted from the second light source, and selectively illuminates and displays the first transmissive portion and the second transmissive portion. The vehicular switch device includes a cylindrical shielding member that extends from the second transmission portion toward the second light source and that allows the light emitted from the second light source to pass through while shielding surrounding diffused light. It is characterized by that.

It is characterized by that.

  According to a third aspect of the present invention, in the vehicle switch device according to the first or second aspect, a lens capable of transmitting light is disposed at least in the second transmission portion, and the light is shielded around the lens. A bush that can be formed is formed, and the shielding member is formed with a convex portion that can come into contact with the bush and can be engaged with the roller member.

  According to a fourth aspect of the present invention, in the vehicle switch device according to any one of the first to third aspects, the shielding member is formed integrally with the operation portion. .

  According to the first aspect of the present invention, the light emitted from the second light source is allowed to pass while the surrounding shielding light from the first light source is shielded by the cylindrical shielding member, so that the light emission amount of the light source is increased. And sufficient lighting display can be performed, and pseudo lighting can be reliably suppressed.

  According to the invention of claim 2, at least the inside of the roller member has a color with a high light diffusion rate (for example, white), and the shielding member has a color with a high light absorption rate (for example, black). While the first transmissive part can be lit and displayed by the light from the first light source and its diffusion, the surrounding light can be absorbed by the shielding part, so that the diffusion light can be prevented from reaching the second transmissive part. it can.

  According to the invention of claim 3, since the convex portion formed on the shielding member is in contact with the bush, the diffused light entering the lens of the second transmitting portion can be further suppressed, and the convex portion is a roller. Since it engages with the member, pseudo lighting can be avoided more reliably, and the assembly of the shielding member is made easier.

  According to the invention of claim 4, since the shielding member is formed integrally with the operation portion, the number of parts can be reduced.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The vehicle switch device according to the present embodiment is fixed to an instrument panel or the like of a vehicle and is used to turn on / off predetermined electrical components such as fog lamps. As shown in FIGS. The roller member 2, the button unit 3 as an operation unit, the first light source 4, the second light source 5, the first transmission unit 6, and the second transmission unit 7 are mainly configured.

  The switch body 1 has an accommodating space for accommodating each component such as the roller member 2 therein, and has rib-shaped locking means 1a on the upper surface and the lower surface thereof. It is configured to be fixed in position. Further, a coupler 1b formed with a connector is fitted on the base end side (right end in FIG. 2) of the switch body 1, and a fixed contact (not shown) formed on the switch body 1 or the first light source. 4 and the second light source 5 can be electrically connected to the vehicle side.

  The roller member 2 is slidable between an ON position (state shown in FIG. 3) and an OFF position (state shown in FIG. 2) of a predetermined switch in the switch body 1, and the movable contact 2a have. Further, the roller member 2 is maintained in the ON position (immersion state with respect to the switch body 1) by a heart cam formed on an action plate (not shown), and when the engagement with the heart cam is released, the return spring 8 It is configured to return to an off position (a protruding state with respect to the switch body 1).

  That is, when the roller member 2 is in the off position, the button member 3 is pressed to slide the roller member 2 against the urging force of the return spring 8, and when the roller member 2 is in the on position, the movable contact 2a is a fixed contact. A predetermined electric circuit is formed in contact with the switch, a predetermined switch is turned on, and the state is maintained by the heart cam. In this on state, when the button portion 3 is pressed again, the engagement by the heart cam is released and the roller member 2 and the button portion 3 slide to the off position by the urging force of the return spring 8, so that the movable contact 2a is fixed. The predetermined switch is turned off at a distance.

  The button portion 3 covers one end side (left end side in FIG. 2) of the roller member 2 and is used for sliding the roller member 2 by the pressing operation of the operator. 2 transmissive portions 7 are formed. The 1st transmission part 6 and the 2nd transmission part 7 are each formed in the position facing the 1st light source 4 and the 2nd light source 5, and are comprised so that the light irradiated from these may be permeate | transmitted, 1st transmission The part 6 is a symbol representing the type of switch, and the second transmission part 7 is a tell tale for visually confirming the ON state of the switch.

  The first light source 4 and the second light source are composed of lamps arranged on the switch body 1 side (specifically, the left end surface in FIG. 2 of the coupler 1b). The first light source 4 is used at night or the like. The second light source 5 is controlled so as to be constantly lit (for example, lit in conjunction with a vehicle headlight or a small lamp), and the second light source 5 is in a state where the roller member 2 is immersed in the switch body 1 (a predetermined switch is It is controlled to light only when it is on.

  Thereby, the lighting display (light transmission by the first light source 4) of the first transmission unit 6 is performed at night or the like to make the type of the switch visible, and the lighting display by the first transmission unit 6 when the switch is on. At the same time, the second transmissive portion 7 is turned on (light transmission by the second light source 5), the state of the switch can be visually recognized, and a selective lit display is made. In addition, in the operation part 3 in this embodiment, although the 1st permeation | transmission part 6 is formed by two-color molding, you may make it form by removing the coating material painted on the surface of the operation part 3. .

  Further, a hole penetrating the front and back is formed at a predetermined portion of the button part 3 (below the first transmission part 6), and a bush 10 extending from the periphery of the hole to the inside (right side in FIG. 2) is formed. Two transmissive portions 7 are formed. The bush 10 is formed of a black portion for shielding light, and a lens 9 is fitted therein, and the light from the second light source 5 is transmitted through the lens 9 so that the second transmission portion 7 is turned on. It is configured to let you. The lens 9 is lit and displayed in a color different from that of the first transmission unit 6 using a predetermined color (blue, green, etc.), and conforms to the regulations.

  On the other hand, the switch body 1 is made of a black resin material having a high light absorption rate, and the roller member 2 is made of a white resin material having a high light diffusion rate. Thereby, in particular, the light emitted from the first light source 4 is directly transmitted through the first transmission unit 6 and the diffused light is also transmitted through the first transmission unit 6, which is a small light source with low power consumption. The first light source 4 can be configured. Further, as shown in FIGS. 4 and 5, a wall portion 2 b that defines a light path by the first light source 4 and a light path by the second light source 5 is formed inside the roller member 2. . The wall 2b is formed integrally with the roller member 2, and is white with a high light diffusivity like the roller member 2.

  Here, in the present embodiment, as shown in FIGS. 4 to 6, the second light source extends from the second transmission unit 7 (lens 9) toward the second light source 5 and shields ambient diffused light. A cylindrical shielding member 11 that allows light emitted from 5 to pass therethrough is provided. That is, the shielding member 11 is formed with a through-hole 11a penetrating in the longitudinal direction thereof, and can pass light from the second light source 5 and has a black light absorption rate. The diffused light is absorbed and shielded so as not to reach the second transmission part 7.

  Thereby, when the predetermined switch is turned off (when the roller member 2 is in the protruding state), the pseudo-lighting due to the diffused light from the first light source 4 wrapping around the second transmission part 7 can be reliably suppressed. Accurate visual recognition of the state can be performed. Further, the provision of the shielding member 11 allows the roller member 2 (including the wall portion 2b) to be configured with a color having a high light diffusivity, and is sufficient without increasing the light emission amount of the first light source 4. Lit display can be performed.

  Further, as shown in FIG. 6, the shielding member 11 is formed with a convex portion 11 b that abuts the bush 10 in a state where the button portion 3 is assembled to the roller member 2 and can be engaged with the roller member 2. . Thus, when the convex part 11b of the shielding member 11 contacts the bush 10, the gap into which the diffused light enters the lens 9 can be eliminated, and the pseudo lighting can be avoided more reliably. At the same time, since the protrusion 11b engages with the roller member 2, the assembly of the shielding member 11 to the roller member 2 is further simplified.

  According to the above embodiment, since the shielding member is extended from the second transmission part 7 toward the second light source 5 and the pseudo lighting is suppressed, the inside of the roller member 2 is lighted to suppress the pseudo lighting. The roller member 2 can be configured with white having a high light diffusivity, so that the diffused light can be used, and the first light source 4 can be made large or Sufficient lighting display can be performed without increasing power consumption.

  Furthermore, the shielding member may be formed integrally with the operation unit 3. Specifically, as shown in FIG. 7, a cylindrical shielding member 11 ′ is integrally formed on the back surface of the operation unit 3 from the second transmission unit 7 toward the second light source 5, and the lens 9 is inserted therethrough. You may make it make it. According to such another embodiment, the number of parts can be reduced as compared with the case where the shielding member is assembled as a separate part.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, the shielding member extends from the second transmission part toward the second light source, and the second diffused light is shielded from surrounding diffused light. If it is a cylindrical thing which allows the light irradiated from the light source to pass through, it is good also as a thing of another color instead of black. Further, it is sufficient that the inside of the roller member constituting the light path by the first light source and the second light source is a color having a high light diffusion rate, and the outer peripheral surface may be another color. The shielding member may be colored by painting.

  Although there may be a plurality of light sources and their transmission parts, each of the transmissions includes a light source that lights when the roller member is in the off position and the on position, and a light source that lights only when the roller member is in the on position. The part needs to be selectively lit and displayed. Furthermore, a color with a high light diffusion rate or a color with a high absorption rate may be a dark color such as dark blue or gray instead of black, and a light color such as yellow or pink instead of white.

  These colors may be the color of the material itself or the color of the paint applied to the surface. Furthermore, although the dimension of the longitudinal direction of a shielding member can be set arbitrarily, it is preferable to extend to the vicinity of the 2nd light source. However, the vehicular switch device according to the present embodiment is a push-lock switch that is mechanically self-holding, but instead of this, for example, a push-return switch provided with a circuit that self-holds inside or outside the switch body. You may apply to switches of other forms, such as (momentary switch).

  If it is a vehicle switch device provided with a cylindrical shielding member that extends from the second transmission portion toward the second light source and allows the light emitted from the second light source to pass through while shielding the surrounding diffused light, The present invention can also be applied to ones having different shapes or to which other functions are added.
