  Light emitting means may be used to decorate the interior of an automobile. For example, a light emitting unit having a light emitting diode is installed in a vehicle to decorate a room.

  An example of such a light emitting unit is described in Patent Document 1 below.

  Patent Document 1 includes “a carpet having a light transmission portion, a base member, and an LED light source installed between or within the carpet and the base member, and the base member includes There is disclosed a floor mat characterized in that the carpet is held at a position where the light from the LED light source is emitted to the outside through the light transmission portion.

JP 2003-210308 A

  The automotive equipment described in Patent Document 1 is a light-emitting diode attached to a floor mat, but it is preferable if the ceiling and side surfaces of the automobile interior can be decorated by light emission. At this time, it is more preferable that the light emitting device is not attached with a large and conspicuous, but can be emitted beautifully with a clean structure with little uncomfortable feeling.

  The present disclosure has been made in consideration of the above-described matters, and relates to an automotive interior decoration structure that uses a light-emitting diode to emit light clearly and beautifully on a ceiling, a side surface, and the like of the automotive interior.

In order to solve the above-mentioned problem, a light emitting diode provided in a back side space located on the back side of an interior trim of an automobile and light from the light emitting diode are emitted to an indoor space located on the front side of the interior trim. 10 or more light guide holes arranged in the interior trim, and the light guide hole includes a through hole formed in the interior trim and having a maximum dimension of an opening of the interior trim surface of 10 mm or less. A light-transmitting light guide member attached to the through hole, and the number of the light emitting diodes is smaller than the number of the light guide holes.
The interior trim includes pillar trims (front pillar trim, center pillar trim, back pillar trim) that cover the pillars of the automobile (the part that connects the body and ceiling of the body panel, also called the window pillar) from the interior side, Includes a roof trim that covers the ceiling from the indoor side.

  In this automobile interior decoration structure, a large number of small light guide holes composed of a through hole having a maximum opening size of 10 mm or less and a light-transmitting light guide member are radiated from a light emitting diode disposed in the back space. Since the emitted light is guided to the indoor space, the ceiling and side surfaces of the automobile interior can be clearly and beautifully emitted. It is easy to arrange a large number of light guide holes so as to describe an arbitrary figure such as a star pattern or a heart mark.

  A first reflecting member that is provided on the back of the interior trim to avoid the position of the light guide hole and reflects light from the light emitting diode, and the first reflecting member is provided on the opposite side of the light emitting diode to emit light A second reflecting member that reflects light from the diode, wherein at least one of the first reflecting member and the second reflecting member has a substantially dish shape with a peripheral edge protruding to the other side. It can also be a decorative structure. The first reflection member and the second reflection member are preferably irregular reflection members that diffusely reflect light from the light emitting diode.

  In this automobile interior decoration structure, the ceiling and side surfaces of the automobile interior can be made to emit light more brightly by the first reflecting member and the second reflecting member even when a relatively small number of light emitting diodes are used.

  The interior of the interior trim surface may have a substantially circular shape with an opening diameter of 10 mm or less, and the light guide member may have a substantially spherical or substantially spheroid shape.

  In this automobile interior decoration structure, since the through hole is substantially circular, it is easy to drill the through hole. Moreover, since the light guide member has a substantially spherical shape or a substantially spheroid shape, it is possible to emit light beautifully on the ceiling, side surfaces, and the like in the automobile interior.

The through-hole has a substantially truncated cone shape whose opening diameter on the interior trim surface is larger than the opening diameter on the back surface of the interior trim, the opening diameter on the interior trim surface is 10 mm or less, and the light guide member is partially from the interior trim surface side. Although it enters into the through-hole, it can also be set as an automobile interior decoration structure having a substantially spherical shape with a size that does not come out to the back side of the through-hole.
Further, the through hole has a substantially truncated cone shape in which the opening diameter of the interior trim surface is larger than the opening diameter of the back surface of the interior trim, the opening diameter of the interior trim surface is 10 mm or less, and the light guide member extends from the interior trim surface side. An automobile interior decoration structure having a substantially spheroid shape having a size that does not come out to the back surface side of the through-hole, although a part thereof enters the through-hole, can also be provided.

  This automobile interior decoration structure can perform an operation of putting a substantially spherical or substantially spheroid light guide member into the through hole from the indoor side. In addition, since the phenomenon that the light guide member falls into the back side of the interior trim due to excessive pressing of the light guide member into the through hole is less likely to occur, workability is high.

  The interior trim of the vehicle may be a pillar trim.

    With this automobile interior decoration structure, the pillar trim located near the position of the passenger's face and relatively easily visible can emit light more clearly and brightly.

  According to the present disclosure, it is possible to provide an automobile interior decoration structure for emitting light clearly and beautifully on a ceiling, a side surface, and the like in an automobile room.

It is sectional drawing which looked at the AA sectional view (surface perpendicular | vertical to a figure) of FIG. 2 from the arrow direction. It is an enlarged view which illustrates the state which removed the light guide member about the Q section of FIG. It is a front view which illustrates the state which removed the pillar trim in FIG. It is the front view equivalent to FIG. 2 which illustrated the vehicle interior decoration structure of the modification.

In FIG. 2 and FIG. 6, only the right light guide hole is denoted by the reference numeral, and the left light guide hole is omitted.

1. Light Emitting Diode A light emitting diode (LED) is a light source in an automobile interior decoration structure. In the automobile interior decoration structure, the light emitting diode is provided in a back space located on the back side of the interior trim of the automobile.

In the present embodiment, as illustrated in FIGS. 1 and 3, the two light-emitting diodes 2 are connected to the back side space S1 located on the back side of the center pillar trim 72, that is, the back side of the center pillar trim 72 and the vehicle body panel 6 (center It is provided in the back space S1 located between the pillar portions. In the present embodiment, the light emitting diode 2 is supplied with power from the automobile battery by a wiring (not shown).
In the automobile interior decoration structure 1, the number of light emitting diodes 2 is smaller than the number of light guide holes 3a and 3b described later. In this embodiment, two light emitting diodes 2 are used.

2. Light Guide Hole The light guide holes 3a and 3b are for radiating light from the light emitting diode 2 to the indoor space S2 (located on the surface side of the interior trim (72)) as illustrated in FIG. A total of 10 or more light guide holes 3a, 3b are arranged in the interior trim (72). A light guide hole was used using a letter of the hole in the sense that light penetrates.

  The number of light guide holes 3a and 3b is more preferably 15 or more, and most preferably 20 or more. In the present embodiment, as illustrated in FIG. 2, five light guide holes 3a having a φ5 mm through hole, 25 light guide holes 3b having a φ2 mm through hole, and a total of 30 light guide holes are centered. They are arranged on the pillar trim 72, and they form a star pattern as a whole. All the light guide holes 3a and 3b are preferably arranged in a range of 20 cm × 20 cm, and more preferably in a range of 10 cm × 10 cm.

  The number of light guide holes 3 a and 3 b is larger than the number of light emitting diodes 2. The automobile interior decoration structure 1 of the present disclosure can emit a large number of light guide holes 3a and 3b with a small number of diodes 2.

  And many light guide holes 3a and 3b are each comprised by the through-holes 30a and 30b and the light guide members 31a and 31b so that it may illustrate in FIG. Hereinafter, these components will be described by way of example.

2-1. Through-holes The through-holes 30a and 30b are formed in the interior trim (72). The opening dimension of the through holes 30a and 30b (the maximum dimension of the opening on the surface of the interior trim (72)) is 10 mm or less. In the automobile interior decoration structure 1, a plurality of relatively small light guide holes are provided to form a pattern or the like as a whole. The lower limit value of the opening size of the through holes 30a and 30b (the maximum size of the opening on the surface of the interior trim (72)) is not particularly limited, but it is 1 mm or more in consideration of the necessity of sufficient light transmission from the light emitting diode 2 Preferably there is.

  Further, as illustrated in FIG. 4, it is preferable that the through holes 30a and 30b have a substantially circular shape (substantially circular shape in the surface view) with an opening diameter φa on the surface of the interior trim (72) of 10 mm or less. Further, the through holes 30a and 30b are preferably formed in a substantially truncated cone shape in which the opening diameter φa on the surface of the interior trim (72) is larger than the opening diameter φb on the back surface of the interior trim.

2-2. Light Guide Member The light guide members 31a and 31b have translucency and are attached to the through holes 30a and 30b. The material of the light guide members 31a and 31b is not particularly limited as long as it has translucency, and those made of glass or various plastics can be used.

  The shape of the light guide member is preferably substantially spherical or substantially spheroidal when the through holes 30a and 30b are substantially circular with an opening diameter φa on the interior trim surface of 10 mm or less. The shape of the light guide member is such that when the through holes 30a and 30b have a substantially truncated cone shape in which the opening diameter φa on the interior trim surface is larger than the opening diameter φb on the back surface of the interior trim, the light guide members 31a and 31b Although the interior trim surface partly enters the through holes 30a and 30b, it is preferably a substantially spherical or substantially spheroid shape having a size that does not come out to the back side of the through holes 30a and 30b. In the case where the light guide member has a substantially spheroid shape (31) and is a rotator (oblong sphere) obtained by using a substantially ellipse as a rotation axis, the light guide member is inserted into the through hole 30b from the longitudinal direction. It is preferable to be in the inserted state.

  Specifically, as illustrated in FIG. 4, in the case of a substantially spherical light guide member 31a, the diameter D1 is smaller than the opening diameter φa on the surface of the interior trim (72) and the opening diameter φb on the back surface of the interior trim (72). Larger is preferred. In the case of a substantially spheroidal (long spherical) light guide member 31b as illustrated in FIG. 3, the maximum diameter D2 of the circular cross section perpendicular to the long axis is the surface of the interior trim (72). The opening diameter φa of the inner trim (72) is preferably smaller than the opening diameter φa.

3. First Reflective Member The first reflective member 4 is for making the light guide holes 3a and 3b emit light more evenly. As illustrated in FIG. 3, the first reflecting member 4 is provided on the back surface of the interior trim (72) so as to avoid the positions of the light guide holes 3a and 3b.
In the present embodiment, the first reflecting member 4 has opening holes at positions corresponding to the light guide holes 3a and 3b, and is attached to the back surface of the center pillar trim 72 so as to avoid the positions of the light guide holes 3a and 3b. Provided by means.

  The first reflecting member 4 is made of, for example, a material having a light reflecting action such as an aluminum film in addition to a mirror. The first reflection member 4 preferably has a diffuse reflection effect. For example, if the film-like aluminum is rolled and then extended, fine irregularities are formed to become a rough surface and have a diffuse reflection effect.

  In addition, although the 1st reflection member 4 can be made into the substantially dish shape which the peripheral part 41 protruded in the other party (2nd reflection member 5 side), as illustrated in FIG. The planar first reflecting member 4 from which the portion 41 does not protrude is used.

4). Second Reflective Member Similar to the first reflective member 4, the second reflective member 5 is for making the light guide holes 3a and 3b emit light more evenly. The second reflecting member 5 is provided on the opposite side of the light emitting diode 2 from the first reflecting member 4.
In the present embodiment, the second reflecting member 5 is provided on the surface of the vehicle body panel 6 (center pillar portion) by means such as sticking, and the light emitting diode 2 is provided on the surface of the second reflecting member 5, The light emitting diode 2 is positioned between the reflecting member 4 and the second reflecting member 5.

  For example, the second reflecting member 5 is made of a material having a light reflecting action such as an aluminum film in addition to a mirror. It is preferable that the 2nd reflection member 5 also has a diffuse reflection effect.

  In the present embodiment, as illustrated in FIG. 3, the second reflecting member 5 has a substantially dish shape in which a peripheral edge portion 51 protrudes on the other side (first reflecting member 4 side).

5. Another Example of Automotive Interior Decoration Structure FIG. 6 illustrates a modified example of the automotive interior decoration structure 1. In this example, in addition to the constituent elements of the automotive interior decoration structure 1 of the above embodiment, a large through body (not shown) having a size exceeding 10 mm (not corresponding to a through hole having a maximum opening of 10 mm or less), and this through It has a light-transmitting star-shaped light guide 91 attached to the body. Thus, for example, a large penetrating body and a star-shaped light guide 91 may be added as an accent to the automobile interior decoration structure.

  The present disclosure has been illustrated and described above with reference to specific embodiments. However, the present disclosure is not limited to the above embodiments, and patents attached to the application of the present application by those skilled in the art. Various changes and modifications can be made without departing from the scope of the claims.

  For example, in the above-described embodiment, only the second reflecting member 5 has a substantially dish shape in which the peripheral edge portion 51 protrudes on the counterpart side (the first reflecting member 4 side), but is not limited thereto. The first reflecting member 4 and the second reflecting member 5 do not have to be substantially dish-shaped. However, it is preferable that at least one of the first reflecting member 4 and the second reflecting member 5 has a substantially dish shape in which the peripheral edge portions 41 and 51 protrude on the other side.

  Moreover, in the said embodiment, although the light emitting diode 2 was directly attached to the surface of the 2nd reflective member 5, it is not limited to this. For example, the light emitting diode 2 may be disposed in the back space S1 located on the back side of the interior trim via a spring means. Specifically, the light emitting diode 2 may be attached to the surface of the second reflecting member 5 or the surface of the vehicle body panel 6 via a leaf spring or a coil spring. As a result, the relative position between the light emitting diode 2 and the light guide holes 3a and 3b changes due to vibration during traveling, and when the vehicle travels, light emitted from the light guide holes 3a and 3b can be visually recognized.

Moreover, in the said embodiment, although the vehicle interior decoration structure 1 was comprised in the center pillar trim 72, it is not restrict | limited to this. For example, the front-pillar trim 71, the back-pillar trim 73, the roof trim 74, and the like can be configured.
