  According to the configuration of the present invention, in a longitudinal garnish that forms a decorative design surface on the outer surface of a vehicle body, such as a front grill, etc., the longitudinal illumination is used in the form of utilizing the space in the longitudinal direction. An illumination unit can be provided. This realizes illumination illumination in which light is leaked from the lens member having a longitudinal transmission reduction effect on the outer surface of the vehicle body at night, etc. Effective lighting can be performed. On the other hand, at the time of non-lighting, since the lens member has a transmission reduction effect, the inside is difficult to see from the outside, and the light source and the light guide member are difficult to see. For this reason, even when there is no light, it is possible to obtain a smart design appearance that does not make the lighting unit or the like conscious. The lens member can be configured by a transmission reducing member that reduces the amount of light transmitted to the inside or outside, or can be configured to include a transmission reduction layer that reduces the light transmittance using the light transmitting member as a base material. it can. In particular, when it is formed on the back surface corresponding to the housing, a unique design can be created by the texture of the lens base material and the texture of the transmission reducing layer.

  The vehicle exterior garnish according to the present invention constitutes a front grille of a vehicle, and a lens member is provided so as to be symmetrical with respect to the center of the front grille, and the light guide member is symmetrical with respect to the center of the front grille. The light sources can be arranged corresponding to one end or both ends of each light guide member. According to this configuration, the illumination can be provided symmetrically with respect to the center of the front grill provided at the front portion of the vehicle, so that the design of the vehicle can be improved.

  In this case, the light source may be arranged only at one end of the light guide member arranged symmetrically with respect to the center of the front grill. As a result, in the left-right direction of the grille, the light guide member emits light with higher luminance toward the end portion on the light source side and decreases in luminance toward the opposite side, thereby expressing a light gradation. It is possible to achieve higher design properties. For example, by arranging light sources only at the center end in the left-right direction of the grill, or by arranging light sources only at the outer end in the left-right direction of the grill, a gradation of light having symmetry on the left and right sides of the grill Can be expressed, and higher designability can be realized.

FIG. 2 is an exploded view of the vehicle exterior garnish of FIG. FIG. 3 is a cross-sectional view of the vehicle exterior garnish of FIG.

  A vehicle exterior garnish 1 in FIG. 1 is a decorative part for improving the appearance of a vehicle, and here has a longitudinal shape that forms a decorative design surface on the outer surface of the vehicle body. The garnish 1 of this embodiment is attached to the vehicle front grille (FIG. 5 (a)) with an outer surface 40 (see FIG. 3) attached to the vehicle front side so as to form an inclined surface that protrudes forward. )) (Hereinafter also referred to as front grill 1). Here, the central portion 1E protrudes forward of the vehicle, and both the longitudinal ends 1R, 1L of the grill extending from the central portion extend obliquely rearward of the vehicle.

  The vehicle exterior garnish 1 shown in FIG. 1 is formed with a longitudinal illumination illumination unit. The illumination illumination unit includes a lens (lens member) 4, a light source unit (light source unit) 7, and a housing 2 from the outside. Realize its function in the form. In the present embodiment, the lens 4 is formed so as to be symmetrical with respect to the center of the garnish 1. The light source unit 7 is located on the back side of the lens 4 and is arranged symmetrically with respect to the center of the garnish 1. That is, the light guide plates 5 are arranged symmetrically with respect to the center of the garnish 1, and the light sources 6 are arranged corresponding to one end or both ends of each light guide plate 5.

  The housing 2 is made of a synthetic resin and is a structure inside the longitudinal garnish 1 and integrally fixes the outer lens 4.

  As shown in FIG. 3, the lens 4 is arranged so as to face the outside of the housing 2, and the outer surface 40 forms an inclined surface that protrudes forward toward the lower side, and is fixed integrally with the housing 2. . The lens 4 has a translucent material (here, a transparent resin material such as acrylic or polycarbonate) as a base material 4M, and has a light transmittance lower than that of the base material 4M on the back surface corresponding to the housing 2. It has a longitudinal shape with a transmission reduction layer 4m. The transmission reduction layer 4m is formed by a vapor deposition process or a sputtering process of a predetermined vapor deposition material (metal (for example, aluminum) or oxide), and these processes make the entire surface light opaque with the material. In other words, it is formed in such a way that a part of light can be transmitted (half vapor deposition).

  In the vehicle exterior garnish 1 of the present embodiment, an emblem portion 1E that is a separately formed symbol mark portion is attached to the central portion of the lens 4 so as to be a light opaque portion in the garnish 1. (See FIG. 1). Further, the lens 4 in the present embodiment has upper and lower ends bent toward the housing 2, and a transmission reducing layer 4 m is also formed on the back surface of a region visible from the outside of the bent portion 4 </ b> C.

  As shown in FIG. 1, the light source unit 7 includes a light guide plate (light guide member) 5 disposed along the longitudinal direction of the lens 4 on the back surface side (housing side) of the lens 4 and light to the light guide plate 5. And a light source 6 for supplying the light source. The light guided to the light guide plate 5 leaks to the outside through the transmission reducing layer 4m (see FIG. 3), and is irradiated to the outside through the lens 4 in an illumination form. Each of the light source units 7 of the present embodiment is arranged in a shape symmetrical to the left and right with respect to the center of the vehicle exterior garnish 1 and is perpendicular to the width direction of the garnish 1 (the longitudinal direction and the thickness direction of the garnish 1). (In this case, two on the left and right sides).

  The light guide plate 5 can be made of a highly transparent material, for example, a transparent resin molded body such as acrylic or polycarbonate. The light guide plate 5 is formed and arranged in a rod shape along the longitudinal direction of the lens 4 on the back side of the lens 4. The light guide plate 5 is difficult to view directly from the outside because the lens 4 including the transmission reduction layer 4m is disposed on the outside thereof.

  The light source 6 is disposed corresponding to one end portion 5 </ b> A (or 5 </ b> B (see FIG. 6)) of the light guide plate 5, and makes light incident on the light guide plate 5. That is, the light from the light source 6 enters the light guide plate 5 from the side end face of the light guide plate 5, and the incident light propagates to the opposite side end face while repeating reflection in the light guide plate 5. The light is emitted from a predetermined light exit surface of the light guide plate 5 facing the surface. Here, in the light guide plate 5 having a rectangular parallelepiped shape and extending in the longitudinal direction of the lens 4, the end surface closest to or in contact with the lens 4 is a light exit surface 5 a, and the surface 5 a (see FIG. 4) leaks light. Therefore, a rough surface is formed by intentionally forming a plurality of holes, scratches, grooves, or slits continuously formed in the longitudinal direction.

  As shown in FIG. 4A, the outer surface of the remaining surface 5 b different from the light exit surface 5 a is surrounded by the reflecting member 8, and the light guide plate 5 is formed as the inner surface 8 b of the reflecting member 8. The light that leaks from the remaining surface 5b is reflected by the reflected surface, and the reflected light is finally emitted from the light exit surface 5a, thereby increasing the amount of light emitted from the light exit surface 5a. Moreover, in the light guide plate 5, as shown in FIG. 4B, a surface 5c (5b) corresponding to the back surface of the light exit surface 5a is a surface facing the side where the light source 6 is disposed (here, the side on the light source 6 side). The inclined surface 5d is formed as an uneven surface repeatedly formed, and the light propagating from the side from the light source 6 is reflected by the side 5d facing the side and emitted from the light exit surface 5a. You may make it do. Either one or both of the reflecting member 8 and the uneven surface 5c can be provided, but they may be omitted if the amount of light emitted from the light exit surface 5a is sufficient.

  In addition, although LED is used for the light source 6 here, it is good also as a fluorescent lamp, a cold cathode tube, etc.

  In this embodiment, the light guide plate 5 is disposed symmetrically with respect to the center of the garnish 1, and the light source 6 is disposed only at one end portion 5A (or 5B (see FIG. 6 and the like)). Thereby, in the left-right direction of the garnish 1, when the light source 6 is turned on, the light guide plate 5 emits light with higher luminance toward the end portion 5A on the light source 6 side, and the luminance decreases toward the end portion 5B on the opposite side. The light emission state is as described above, and light gradation is expressed in the entire light guide plate 5. Here, the light source 6 is arranged only at the center side end portion 5A of the garnish 1 with respect to both the left and right light guide plates 5 and 5, and light enters the light guide plate 5 from the center side of the garnish 1, so that the garnish 1 The gradation of light that is brighter toward the center side of is expressed.

  Here, the light source 6 is a board on which an LED is mounted, and is located on the back side of an emblem part 1E that forms a light-opaque part provided in the center part of the front grill 1, and is another printed board via a wire harness. It is connected to the. This printed circuit board is disposed on the back side of the emblem 1E, more specifically, on the back side of the housing 2 located on the back side of the emblem 1E. In this case, since the light source 6 is disposed near the center of the front grill 1, the length of the harness can be shortened. The lens 2 has an opening (not shown) in the center, and an emblem 1E and a mounting portion are formed in the center on the front side of the housing 2 located on the inner side of the opening. It attaches to this attaching part, and is arrange | positioned so that the center opening of the lens 2 may be covered.

  Hereinafter, the vehicle exterior garnish 1 of this embodiment will be described in more detail.

Is visually recognized from the outside as a substantial design surface. Here, a colorless or colored transparent (clear or color clear) coating is made on the back surface of the base material 4M as the base coating 41, and a transmission reducing layer 4m is formed. Various metallic expressions (mirror surface and matte) are possible by changing the paint and color of the base coating 41. In addition, if the lens 4 is cut on the back surface of the lens 4 to form a concavo-convex shape, the lens 4 can be visually recognized so as to include a member having a metal texture, a so-called reflector.

  In the cross section perpendicular to the longitudinal direction of the housing 2 (see FIG. 3), the groove portion (see FIG. 3) is recessed so that the outer surface 40 is away from the lens 4 from the main surface portion 2 </ b> A facing substantially parallel to the inclined lens 4. In this case, it can be said to be a concave bent portion). In the groove 3D, the light guide plate 5 whose outer peripheral surface excluding the light exit surface 5a is surrounded by the reflecting member 8 is fixedly installed, and the light exit surface 5a is arranged so that the light emitted from the light guide plate 5 is directed to the lens 4 side. It is provided as a surface facing at least the outside (front side) of the vehicle. Here, the light exit surface 5a is an obliquely upward surface on the outer side (front side) of the vehicle such that the light emitted therefrom is more horizontal than the tilt direction of the lens outer surface 40 in the cross section of FIG. It is provided as. When the light source 6 is lit, the light emitted from the light exit surface 5a of the light guide plate 5 is directly incident on the lens 4, and a predetermined region (light emitting surface) R (see FIG. 1B) of the outer surface 40 by the incident light. ) Emits light.

  In the present embodiment, the light from the light guide plate 5 passes through the space 2S formed between the lens 4 and the housing 2 in which the light guide plate 5 is fixedly installed, as shown in FIG. Then head to lens 4. The space 2S is waterproofed by being sealed with respect to the outside.

  With the above configuration, the front grill 1 constituting the vehicle exterior garnish according to the present embodiment looks like a normal lens-type grill when there is no light during the daytime, but can be used as an illumination grill (lighted grill) when the light is illuminated at night or the like. . In the present embodiment, as shown in FIG. 1 (b), at the time of lighting at night or the like, a strip-shaped light emitting surface R extending linearly in the left-right direction is visually recognized on both the left and right sides excluding the central portion of the front grill 1. . In addition, since a gap is interposed between the light exit surface 5a and the lens 4 (transmission reducing layer 4m), the outer surface 40 of the lens 4 emits light slightly in the form that the periphery of the light emitting surface R is weaker than that. Light emission state.
