Description

  The present invention relates to an illuminating device that illuminates a vehicle interior in a vehicle such as an automobile, and more particularly to an illuminating device in a vehicle interior in which an illumination member having a light guide property is arranged on an instrument panel at the front of the vehicle interior.

  2. Description of the Related Art In recent years, in vehicles such as automobiles, a lighting device that illuminates the interior of a vehicle at night or the like has been generally used for the purpose of improving the interior of the vehicle interior and creating a more calm atmosphere when illuminated. It is considered that indirect lighting is adopted instead of so-called direct lighting. In this indirect illumination, the direct illumination from the illumination member that emits illumination light is not performed as in direct illumination, but the illumination light from the illumination member is reflected by a nearby wall surface and the like, and the reflected light is used. Since the illumination is performed, it is possible to suppress the entire vehicle interior, the illumination target, and the vicinity thereof from becoming excessively bright as in the case of direct illumination, and a more calm and calm atmosphere can be created.

Further, conventionally, as a lighting device in a vehicle interior of a vehicle such as an automobile, a lighting member having a light guide property is arranged in a vehicle interior member, and the lighting member is irradiated with light from a light source provided inside or outside the lighting member Is known, and the interior of the vehicle is illuminated with the light.
For example, in Patent Document 1, a light guide plate is provided inside a light-transmitting panel, a light source (for example, a light emitting diode) is disposed on the side of the light guide plate, and light from the light source is introduced into the inside from the side surface of the light guide plate. An article that enters and exits from the surface of the light guide plate is disclosed.

Patent Document 1 discloses a vehicle illumination device in which the above-described illumination member is disposed on a center console box, a ceiling above a rearview mirror, an instrument panel, a door panel, or the like. .

By the way, in the instrument panel disposed in the front part of the passenger compartment of the automobile, various equipment and switches are disposed, and in order to ensure convenience when using or operating them at night or the like. Lighting is needed.
However, conventionally, when an illumination member is provided on the instrument panel, the illumination light from the illumination member may easily enter the field of view of the occupant seated on the front seat in the passenger compartment, which may be annoying. In particular, when the illumination light directly enters the driver's field of view, driving during illumination such as at night becomes difficult and an impediment is felt.
In addition, even when the illumination provided on the instrument panel is indirect illumination, depending on the position where the illumination member is provided and the direction of the illumination light, etc., if the part illuminated by the illumination light is illuminated very brightly, the front seat May be annoying for seated passengers.

  The instrument panel usually has a front edge located in the vicinity of the lower edge of the front (window) glass. Further, depending on the type of vehicle, there is also a case where the front side edge is positioned near the lower edge of the front side (window) glass. Therefore, when the operation section of the instrument panel itself or the equipment arranged there is illuminated very brightly by the indirect lighting as described above, the illuminated operation section etc. There is also a problem that so-called reflection, which is reflected on the window glass and enters the field of view of the occupant, is likely to occur, and this reflection is also obstructive for the seated occupant of the front seat.

On the other hand, the left side portion of the center console portion 16 of the instrument panel 10 is positioned in front of a passenger seat (not shown) and includes a glove box 17 as an accessory case. An air-conditioning air outlet 43 </ b> A is located above the left end portion of the glove box 17. A cup holder 36 is provided so as to be able to be pulled out immediately below the air conditioning outlet 43A at the left end of the passenger compartment and the air conditioning outlet 43D at the right end of the passenger compartment.
Further, door mirrors 23 and 24 as side mirrors for mainly viewing the rear side of the vehicle are provided at the front end portions of the left and right front doors 21 and 22, respectively.

  The air conditioning setting dial 41 (41A, 41B, 41C), the audio operation button 42 (42A, 42B, 42C, 42D) and the air conditioning outlet 43 (43A, 43B, 43C, 43D) are specific to them. Except for the case where it is necessary to distinguish and describe, the alphabetical code is appropriately removed and the air conditioning setting dial 41, the audio operation button 42, and the air conditioning outlet 43 are displayed in a simplified manner.

In the present embodiment, the instrument panel 10 is preferably composed of an upper part 11 constituting the upper part and a lower part 12 constituting the lower part. The center console portion 16 is configured by assembling another member to the instrument panel 10. In the assembled state, the inclined portion of the center console portion 16 corresponds to the lower portion 12 of the instrument panel 10. Is. The center console portion 16 can be integrally formed with the lower portion 12 of the instrument panel 10.
A stepped portion S that extends in the vehicle width direction and divides the instrument panel 10 into upper and lower portions is formed at a boundary portion between the upper portion 11 and the lower portion 12, and the stepped portion S has a light guide property. Member 2 is arranged. More preferably, the stepped portion S and the illumination member 2 are extended over substantially the entire width of the instrument panel 10.

Hereinafter, the stepped portion S and the illumination member 2 will be described.
2 is a perspective view showing the basic structure of the stepped portion S of the instrument panel 10, and FIGS. 3 and 4 show the stepped portion S on the upper side of the center console portion 16 and the stepped portion S on the upper side of the glove box. It is a perspective view which shows each structure.
As shown in FIG. 2, the stepped portion S has an upper surface 11f (stepped upper surface) located on the upper side folded back obliquely forward and downward, and a front end portion of the folded portion 11b (also a lower end portion of the stepped upper surface portion). And the lower end surface 12f (step lower surface) located on the lower side is engaged with the front end portion (which is also the upper end portion of the step lower portion surface), and the rear end portion 11p of the step upper surface 11f is formed. It is set to project to the vehicle rear side from the front end 12p of the step lower surface 12f.

  And the illumination member 2 is arrange | positioned so that it may extend in the vehicle width direction in the deepest part in this level | step-difference part S, ie, the vicinity of the front-end part 12p of the level | step difference lower surface 12f. As schematically shown in FIG. 6, the lighting member 2 is formed in, for example, a long rod shape or a column shape using a light-guiding material such as an acrylic resin or a polycarbonate resin. A light source 4 (for example, a light emitting diode, a halogen lamp, an incandescent lamp, etc.) is disposed on the side of one end face in the direction.

The light from the light source 4 enters the inside from the end face of the illumination member 2 and exits from the surface of the illumination member 2 to perform illumination, which is conventionally known.
Instead of separately providing the light source 4 as described above, it is also possible to perform illumination by arranging a linear or dot light source inside the illumination member. Moreover, since the above-mentioned material has flexibility, even a curved portion that bends with a certain degree of curvature can be laid without hindrance.

  As shown in FIG. 5, a groove portion 11g having a substantially U-shaped cross section that opens downward is formed in the vicinity of the front end portion of the folded portion 11b of the upper portion 11 so as to extend in the vehicle width direction. The lighting member 2 is accommodated in the groove 11g. The groove 11g that accommodates the illumination member 2 is open so as to face the step lower surface 12f, and the opening is closed by a cover body 13 (clear clear cover body) as a substantially transparent member that can be seen through. Thus, the clear cover body 13 protects the illumination member 2 housed inside.

The clear cover body 13 is made of, for example, an acrylic resin that can be substantially seen through. For example, as shown in FIGS. The direction of the illumination light from the member 2 can be adjusted and set.
Since the illumination light from the illumination member 2 is irradiated to the inside of the clear cover body 13 downward from the upper edge portion of the substantially transparent see-through cover body 13, the clear cover body 13 indirectly The area to be illuminated can be adjusted in advance. For example, even when traveling in a tunnel or at night, a portion that is indirectly illuminated is suppressed from being reflected on the windshield 20 or the side glass, and such reflection is annoying for the passengers. Can be suppressed. In addition, the illumination area can be laid out with a relatively simple configuration by the clear cover body 13.

Thus, since the groove 11g that accommodates the illumination member 2 is opened so as to face the step lower surface 12f, the light emitted from the surface of the illumination member 2 is indicated by a one-dot chain arrow in FIG. The light passes through the clear cover body 13 and first enters the step lower surface 12f. Then, illumination is performed with the reflected light. That is, the interior of the vehicle is illuminated by so-called indirect illumination.
Therefore, for example, when the interior of the vehicle interior needs to be illuminated, such as when traveling in a tunnel or at night, the entire interior of the vehicle interior is not brightened by illuminating the instrument panel 10 with illumination light from the illumination member 2. In addition, the occupant can easily recognize the position of the instrument panel 10.

  In the vicinity of the stepped portion S of the stepped upper surface 11f of the instrument panel 10, the rear end portion 11p of the stepped upper surface portion 11f (see FIG. 5) is provided in order to increase the degree of visibility of the stepped upper surface 11f. A line-shaped decorative board 30 is affixed in a relatively conspicuous color.

In this case, the illumination light from the illumination member 2 is irradiated to the inside of the clear cover body 13 from the upper edge of the clear cover body 13 that can be substantially seen through, and the clear cover body 13 The irradiation direction and the indirect illumination area are adjusted in advance so that the illumination light is diffused in a wide area of the instrument panel 10 and the operation unit below the illumination member 2.
Then, when a passenger seated in a front seat (not shown) (driver's seat or passenger seat) visually recognizes this illuminated area in its seated posture, the line of sight is indicated by a two-dot chain line arrow e in FIG. The illumination member 2 itself never enters the field of view by being blocked by the step upper surface 11f. In addition, the size and positional relationship of each part are set so that the illumination light directly emitted from the illumination member 2 is not blocked directly by the stepped upper surface 11f and thus does not directly enter the passenger's field of view. ing.

  As described above, since indirect illumination can be performed, it is possible to prevent the illumination portion and its vicinity from becoming excessively bright as in the case of direct illumination, and the interior of the vehicle can be made more calm and relaxed. . Moreover, the illumination light from the illumination member 2 is set so as not to directly enter the field of view of the occupant seated in the front seat of the passenger compartment, so that illumination is obstructive for the occupant seated in the front seat. This can be suppressed more reliably. In particular, it is possible to more reliably prevent the driver from getting into the eyes and making it difficult to drive, reducing the feeling of hindrance when driving in situations that require lighting in the passenger compartment, such as when driving in a tunnel or at night. be able to.

Furthermore, since the illumination member 2 that performs the indirect illumination as described above is extended over substantially the entire width of the instrument panel 10, a portion above the illumination area of the instrument panel 10 is illuminated at night or the like. By giving the impression that almost the entire carp has been raised, the interior of the passenger compartment can be enhanced and a sense of luxury can be created.
In the present embodiment, the stepped portion S and the lighting member 2 extend over substantially the entire width of the instrument panel 10, but the stepped portion S and the lighting member 2 are limited to a specific range in the vehicle width direction as necessary. The illumination member 2 may be provided.

  Next, a second embodiment of the present invention will be described. In the following description, components having the same configuration as those in the first embodiment and having the same operational effects are denoted by the same reference numerals, and further description thereof is omitted.

The shift lever 53 of the transmission is attached so as to protrude through the vehicle interior. Further, the clear panel 60 is provided with notches such as “P”, “R”, “N”, “D”, “+”, “−” and the like indicating the shift position of the shift lever 53 (for example, concave engraved characters). Is displayed. Further, a cup holder 54 is provided in a relatively upper portion of the rear end surface of the console portion 51 and slightly below the clear panel 60 so as to be able to appear and retract in the vehicle front-rear direction.

  In the above configuration, when the illumination light of the illumination member 50 is irradiated from the upper edge portion 60a of the clear panel 60 to the inside of the clear panel 60, a part of the illumination light irradiated in the clear panel 60 is penetrated through the above-described configuration. By radiating from each upper vertical wall of the groove portion 61, the illumination light illuminates a wide area of the surface covered with the clear panel 60 in the console portion 51 while being diffused, and an extremely bright portion is formed. Therefore, the driver's driving is not hindered. The light traveling in the clear panel 60 is emitted toward the lower side of the through groove 61 from the surface of the through groove 61, in particular, the vehicle width direction facing the upper edge 60 a of the clear panel 60. Illuminate the inside of the groove 61. As a result, the entire line formed by the through-groove 61 appears to be raised by light, and the vicinity of the through-groove 61 of the shift lever 53 is also illuminated, so that the visibility is improved and the interior is improved. In addition, the visibility of the signs “P”, “R”, “N”, “D”, “+”, “−” and the like indicating the shift positions displayed in the unevenness is similarly increased. Furthermore, interior property can be improved also about the whole part covered with the said clear panel 60 of the console part 51. FIG.

  In this case, the illumination light of the illumination member that performs indirect illumination using the clear panel 60 is used for position recognition and display of the shift lever 53, and further, symbols “P”, “N”, It can be used for recognition of “1”, “2” and the like.

  Further, part of the illumination light emitted from the upper edge portion 60 a of the clear panel 60 is radiated from the lower edge portion 60 b of the clear panel 60. Therefore, when the cup holder 54 located below the lower edge portion 60b of the clear panel 60 is in the stored state, the handle portion 54b can be illuminated. Further, as shown in FIG. 8, when the cup holder 54 is in the pulled-out state, the inside of the drawn cup holder 54 can be illuminated, so that the visibility of the cup holder 54 is increased and convenience is increased.
