<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram schematically showing a back surface of a door trim 10 to which a vehicle lighting device 30 according to an embodiment of the present invention is attached.

  The door trim 10 (vehicle interior material) is attached to the vehicle interior side of the door inner panel 11 via, for example, a clip (not shown). The door trim 10 includes a trim board 12 and an ornament 14 (shown in FIG. 2) attached to the trim board 12. The trim board 12 and the ornament 14 are partially (or entirely) covered with skin material 12A, 14A made of animal skin (genuine leather) such as cowhide. In addition, as the skin materials 12A and 14A, a synthetic resin sheet, a woven fabric, a non-woven fabric, or the like can be used.

  The trim board 12 is formed of a synthetic resin material or a material obtained by mixing natural fibers (such as kenaf) with a synthetic resin material. A part (or the entire surface) of the trim board 12 is covered with a skin material 12A formed of animal skin (genuine leather) such as cow leather. In addition, as the skin material 12A, a synthetic resin sheet, a woven fabric, a non-woven fabric, or the like can be used.

  As shown in FIGS. 1 and 2, the trim board 12 is provided with a speaker 16, a door pocket 18, an armrest 20, an inside handle 22, and the like. The armrest 20 is arranged so as to project to the vehicle interior side of the trim board 12. A part of the upper surface of the armrest 20 is opened upward, and a pull handle 21 is attached to the opening.

  The inside handle 22 is used to open and close the vehicle door, and is housed in a handle housing portion 23 arranged in the trim board 12 so as to open to the vehicle interior side. In addition, in FIG. 1, the back wall of the handle accommodating part 23 is abbreviate | omitted.

  On the trim board 12, the vehicle lighting device 30 of this embodiment is attached to a total of three locations. Each vehicle lighting device 30 is for illuminating the inside handle 22, the pull handle 21, and the door pocket 18, respectively. Since each vehicle lighting device 30 has the same configuration, in the following description, the vehicle lighting device 30 provided on the inside handle 22 will be described.

  As shown in FIGS. 1, 3, and 6, the vehicular illumination device 30 covers an LED 31 (light source), a light guide bar 33, and a part of the light guide bar 33 (the other end 34 described later). The cap member 35 attached to the trim board 12, the first holding part 50 for holding the light guide rod 33 formed on the trim board 12, and the fitting claw 55 for attaching the cap member 35 are mainly used. It is configured.

  The LED 31 is a light source for introducing light into the light guide rod 33 and is housed inside the case 32 as shown in FIG. The LED 31 is connected to a power source such as a battery mounted on the vehicle via a control device (not shown).

  The light guide bar 33 is made of a long (tube-shaped) light guide material having a substantially circular cross section. Here, the “light guide material” is a material that transmits light, such as an acrylic resin. As such a light guide material, for example, a known light guide material disclosed in Japanese Patent Laid-Open Nos. 2005-306233 and 6-75120, which are public patents, can be used.

  As shown in FIG. 6, one end portion 39 in the longitudinal direction of the light guide bar 33 is attached to the case 32, and the end surface 33 </ b> A on the one end portion 39 side is arranged to face the light emitting surface 31 </ b> A of the LED 31. Thus, the end surface 33A on the one end side is a light incident surface (light incident portion) on which the light emitted from the LED 31 is incident. In the following description, the end surface 33A on the one end side may be referred to as a light incident surface 33A.

  The outer peripheral surface 33D and the other end surface 33B of the light guide bar 33 are subjected to a process such as coating with a fluorine-based resin, and emit light introduced into the light guide bar 33 to the outside. It is supposed to be configured. That is, the outer peripheral surface 33D and the other end surface 33B of the light guide bar 33 serve as a light emission surface (light emission part) that emits the light that has entered the light guide bar 33 from the light incident surface 33A to the outside. . In the following description, the end surface 33B on the other end side may be referred to as a light emitting surface 33B.

  Next, the configuration of the cap member 35 will be described. The cap member 35 is disposed on the other end portion 34 of the light guide bar 33, covers the other end portion 34, and has a function of holding the light guide bar 33 against the trim board 12. The cap member 35 also has a function of emitting light emitted from the light emitting surface 33 </ b> B of the light guide bar 33 toward the irradiation target (in this case, inside the handle housing portion 23).

  The cap member 35 is made of a material that transmits light, such as acrylic synthetic resin. As shown in FIGS. 6 and 7, the extending direction of the light guide bar 33 (the left-right direction in FIGS. 6 and 7). And a distal end portion 37 extending from the end portion of the main body portion 36 so as to be bent at a substantially right angle. The main body portion 36 is disposed so as to cover the other end portion of the outer peripheral surface 33D of the light guide rod 33, and the tip portion 37 covers the light emission surface 33B of the light guide rod 33 (opposing the light emission surface 33B). ). Further, in the trim board 12, a light emission hole 23 </ b> B is formed through the portion facing the tip portion 37.

  As shown in FIG. 6, on the outer peripheral surface of the distal end portion 37 of the cap member 35, the surface far from the light emitting surface 33B of the light guide bar 33 among the surfaces facing the light emitting surface 33B of the light guide bar 33 is The light reflecting surface 37A (light reflecting portion) is used. The light reflecting surface 37A is an inclined surface that is directed toward the light emitting hole 23B as it is farther from the light emitting surface 33B of the light guide bar 33. The light reflecting surface 37A transmits light emitted from the light emitting surface 33B of the light guide bar 33 inside the handle accommodating portion 23 ( It is for reflecting toward the irradiation target). Such a light reflecting surface 37 </ b> A is formed, for example, by applying a paint having a color excellent in light reflectivity (such as white) to the outer peripheral portion of the cap member 35. Further, the means for forming the light reflecting surface 37A is not limited to this. For example, the light reflecting surface 37A is attached to the outer peripheral portion of the cap member 35 such that the light reflecting surface of the light reflecting sheet having light reflectivity faces the light emitting surface 33B. You may form by attaching.

  With the above configuration, light emitted from the light emitting surface 31 </ b> A of the LED 31 enters the light guide rod 33 from the light incident surface 33 </ b> A of the light guide rod 33, and is guided by repeating total reflection inside the light guide rod 33. Is done. Further, a part of the light guided inside the light guide bar 33 is emitted from the outer peripheral surface 33D of the light guide bar 33 to the outside without being totally reflected (light ray L2 shown in FIG. 6). . Thereby, the whole light guide bar 33 becomes a linear light source, and it is possible to illuminate the periphery.

  On the other hand, out of the light guided inside the light guide rod 33, the light emitted from the light emitting surface 33 </ b> B enters the front end portion 37 of the cap member 35. Then, the light reaching the light reflecting surface 37A is reflected toward the light emitting hole 23B side (as a result, inside the handle accommodating portion 23 to be irradiated), and the surface 37B (opposite to the light emitting hole 23B in the tip portion 37). The light is emitted from the cap side light emitting surface 37B). The light emitted from the cap-side light emission surface 37B passes through the light emission hole 23B and is emitted to the handle housing portion 23 (light beam L1 shown in FIGS. 4 and 6). Thereby, the inside of the handle accommodating part 23 can be illuminated with the light from the LED 31.

  Further, in the tip portion 37, the cap side light emitting surface 37B facing the light emitting hole 23B is a substantially hemispherical lens portion that is recessed toward the light reflecting surface 37A. Thereby, the light emitted from the cap-side light exit surface 37B can be condensed, which is suitable for passing through the light exit hole 23B. Further, for example, if the cap-side light exit surface 37B is formed in a convex shape toward the light exit side (the light exit hole 23B side), it is possible to diffuse the light emitted from the tip portion 37, and a wider range. Suitable for illuminating

  In this embodiment, the cap member 35 can be attached to the trim board 12 by fitting the fitting claw 55 formed on the trim board 12 side into the fitting hole 38A formed in the cap member 35. It has become. More specifically, as shown in FIGS. 3 and 7, plate-like attachment portions 38 are respectively formed at both ends in the short side direction of the main body portion 36. Each attachment portion 38 is formed with a fitting hole 38A. As shown in FIGS. 3 and 7, both attachment portions 38 are arranged at different positions (in a shifted form) in the long side direction of the main body portion 36 (the left-right direction in FIG. 7). .

  Further, as shown in FIGS. 3 and 4, in the trim board 12 (more precisely, the upper wall portion 23A constituting the handle housing portion 23), the mounting location (more specifically, the fitting hole) of the cap member 35 is provided. 38. A fitting claw 55 that can be fitted into each fitting hole 38A is formed at a position facing 38A.

  As shown in FIGS. 3 and 7, the fitting claw 55 is formed integrally with the trim board 12 so as to protrude toward the cap member 35, and elastically deforms in the left-right direction in FIG. 5 with its base end as a fulcrum. It is possible. The distal end portion of the fitting claw 55 serves as a locking portion 56 that can be locked to the mounting portion 38 after being inserted into the fitting hole 38A.

  As shown in FIG. 5, in the locking portion 56, the surface far from the cap member 35 is a guide surface 56 </ b> A that is inclined toward the side closer to the cap member 35 toward the distal end side of the fitting claw 55. The guide surface 56A slides with respect to the edge of the fitting hole 38A in the mounting portion 38 when the fitting claw 55 is fitted into the fitting hole 38A. 55 to guide the fitting with 55.

  Next, a configuration for holding the other end portion 34 of the light guide bar 33 by the cap member 35 will be described. The other end portion of the light guide rod 33 is configured to be sandwiched between a first sandwiching portion 50 formed on the trim board 12 and a second sandwiching portion 40 formed on the main body portion 36 of the cap member 35. ing.

  The first clamping unit 50 is formed in a shape protruding from the trim board 12 toward the cap member 35, and has a flat plate shape that is long in the extending direction of the light guide bar 33. The second sandwiching portion 40 extends from the end portion of the main body portion 36 (the left end portion in FIG. 5) so as to be bent at a substantially right angle toward the trim board 12 side. It has a long plate shape in the installation direction.

  In the state where the cap member 35 is attached to the trim board 12 (the state shown in FIG. 5), the first sandwiching portion 50 and the second sandwiching portion 40 are arranged to face each other, and the first sandwiching portion 50 and the second sandwiching portion 40 are arranged. Is configured to be slightly smaller than the outer diameter of the light guide bar 33. Thereby, the light guide rod 33 can be clamped between the first clamping unit 50 and the second clamping unit 40.

  As shown in FIG. 3 and FIG. 5, at both ends in the long side direction of the first sandwiching portion 50, ribs having an inclined surface 51 </ b> A on the surface opposite to the light guide rod 33 side and having a substantially triangular shape. 51 are formed. The inclined surface 51 </ b> A (guidance surface 51 </ b> A) of the rib 51 is inclined away from the light guide bar 33 toward the trim board 12.

  On the other hand, from the end of the main body 36 in the cap member 35 (the end on the right side in FIG. 5, the end opposite to the side on which the second clamping portion 40 is formed) is substantially toward the trim board 12 side. An extending portion 41 is extended in a shape that bends at a right angle. The inner peripheral surface (guided surface 41A) of the extended portion 41 is inclined along the guide surface 51A (that is, at substantially the same angle as the tilt angle of the guide surface 51A).

  When the cap member 35 is attached to the trim board 12, if the guided surface 41A slides on the guide surface 51A, the cap member 35 moves to the first clamping unit 50 side (right side in FIG. 5). . As a result, the interval between the first clamping unit 50 and the second clamping unit 40 is narrowed, and the other end of the light guide rod 33 is clamped between the first clamping unit 50 and the second clamping unit 40. It has become.

  Next, the operation and effect of the vehicular lighting device 30 of the present embodiment will be described. First, a procedure for attaching the cap member 35 to the trim board 12 will be described. The other end portion of the light guide rod 33 (the side where the LED 31 is not disposed) is placed close to the first holding portion 50, and the fitting holes 38A of the cap member 35 are fitted into the fitting claws 55, respectively. (Shown with a dashed line in FIG. 5).

  At this time, when the cap member 35 is pressed toward the trim board 12, the edge of each fitting hole 38A pushes the guide surface 56A of each corresponding locking portion 56, and each fitting claw 55 has its base end as a fulcrum. Then, it is elastically deformed to the inside (light guide rod 33 side). When the cap member 35 is further pressed, the locking portions 56 are inserted into the fitting holes 38A. Eventually, when the locking portion 56 passes through the fitting hole 38A, the fitting claw 55 is elastically restored, and the locking portion 56 is locked to the mounting portion 38 (state of FIG. 5). That is, after the edge of the fitting hole 38A in the mounting portion 38 is brought into contact with the guide surface 56A, the edge of the fitting hole 38A is slid on the guide surface 56A, thereby engaging with the fitting hole 38A. The fitting with the stopper 56 is guided.

  Simultaneously with the fitting of the fitting holes 38A and the fitting claws 55, the guided surface 41A of the cap member 35 is slid on the first clamping unit 50 guiding surface 51A, so that the first clamping unit 50 is engaged. And the distance between the second clamping unit 40 and the second clamping unit 40 are reduced. In the state where the locking portion 56 is locked to the mounting portion 38, the other end portion 34 of the light guide rod 33 is held between the first holding portion 50 and the second holding portion 40. .

  As described above, in the vehicle lighting device 30 of the present embodiment, the other end portion 34 of the light guide bar 33 can be sandwiched with a simple configuration such as attaching the cap member 35 to the trim board 12. The light guide bar 33 can be held against the trim board 12. Also, if the other end portion 34 of the light guide bar 33 is clamped, for example, the light guide bar 33 can be attached more securely than a configuration in which the light guide bar 33 is hooked and held by a hook-like engaging claw or the like. This can also prevent the light guide bar 33 from being damaged during installation.

  Further, in the present embodiment, a fitting claw 55 and a fitting hole 38A that can be fitted to the fitting claw 55 are provided, and the engaging portion 56 of the fitting claw 55 has an end of the fitting hole 38A. A guide surface 56A for guiding the fitting between the fitting claw 55 and the fitting hole 38A by sliding with respect to the portion is formed.

  With such a configuration, the cap member 35 can be attached to the trim board 12 by fitting the fitting claw 55 into the fitting hole 38A. Further, since the guide surface 56A for guiding the fitting between the fitting claw 55 and the fitting hole 38A is formed, the two members can be easily fitted.

  In addition, a light exit surface 33B is disposed on the other end portion 34 of the light guide bar 33, and a light reflecting surface 37A capable of reflecting the emitted light from the light exit surface 33B toward the irradiation target is formed on the cap member 35. ing.

  With such a configuration, the emission direction of the emission light can be changed by reflecting the emission light from the light emission surface 33B of the light guide bar 33 by the light reflection surface 37A. Thereby, light can be emitted toward the irradiation target regardless of the direction of the light emitting surface 33 </ b> B of the light guide rod 33. In addition, if the light reflecting surface 37A is formed on the cap member 35 that is a member that holds the other end portion 34 of the light guide bar 33, it is not necessary to provide another member for reflecting the light.

  The cap member 35 is formed with a lens portion (cap-side light emission surface 37B) that can collect (or diffuse) the light emitted from the light emission surface 33B. By condensing (or diffusing) the emitted light from the light emitting unit by the lens unit, the irradiation range can be changed.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, the cap member 135 is the same as the above embodiment in that the main body portion 136 and the distal end portion 137 are configured. The point which is formed in the shape which opposes the light-projection surface 33B of the stick | rod 33 differs from the said embodiment.

  Thereby, the light emitted from the light emitting surface 33B can be reflected by the light reflecting surface 137A and can be incident again into the light guide rod 33 from the light emitting surface 33B (indicated by the light beam L3). In general, in the light guide rod 33, the other end portion 34, which is the portion farthest from the LED 31 (not shown in FIG. 8), tends to have a smaller amount of light than other portions. In this regard, in the present embodiment, the amount of light emitted from the other end portion 34 of the outer peripheral surface 33D in the light guide bar 33 can be increased by allowing light to enter the light guide bar 33 from the light output surface 33B. The situation where the other end portion 34 becomes darker than other portions can be suppressed.

  The light reflecting surface 137A has a convex shape protruding toward the light emitting surface 33B, and has a configuration in which light reflected by the light reflecting surface 137A is diffused. Thereby, in the other end part 34 of the light guide bar 33, the situation where the light reflected by the light reflection surface 137A is locally emitted from the outer peripheral surface 33D can be suppressed. In other words, light can be emitted more uniformly from the outer peripheral surface 33D, and uneven brightness can be suppressed.
