Therefore, conventionally, generally, the boundary portion is connected to the line by, for example, matching a step or a groove forming a so-called design line extending in the front-rear direction of the vehicle from the door portion on the side surface of the vehicle to the rear side outer panel in the front-rear direction of the vehicle. The vehicle design is integrated with the feeling. However, even if the combination lamp is provided with such design considerations, the tailgate garnish provided so as to be externally connected to the combination lamp only gives a flat impression as described above. In this case, the image of the vehicle connected to the design line is interrupted, and the decorative effect of the tailgate garnish cannot be sufficiently exhibited.

The present invention has been made in view of such circumstances, and has as its object to produce a design image having a sense of depth with a simple structure, for example, a tailgate. An object of the present invention is to provide an automobile decorative panel device suitable for use as a garnish.

[0007]

In order to achieve the above-mentioned object, a decorative panel device for an automobile according to the present invention comprises a decorative cover made of a light-transmitting synthetic resin material, and a decorative cover for supporting the decorative cover. And a base for attaching the base to the vehicle body, and in particular, a surface of the base opposed to the back surface of the decorative cover has at least a shallow wide recess.

As shown in FIG. 3 (a), a panel body 7a having an appearance shape forming an integral connecting surface with the outer surface of the tailgate panel 2 and having a substantially uniform thickness (for example, about 3 mm) as a whole. Is formed. The panel body 7a has a glossy smooth surface over its entire surface, and has a minute lens surface 7b formed continuously on its back surface as shown in FIG. 3 ( b ). It forms a panel surface that emits light.

The lens surface 7b is, for example, 3 mm × 5
The micro lens is formed continuously by using a rectangular area of about mm as a unit and forming an arc surface with a radius of about 7 mm on the surface. Further, a flange 7c protruding from the rear surface side of the panel body 7a is formed as a mounting portion for attaching the decorative cover 7 to the base 8. The decorative cover 7 is colored, for example, red according to the color tone of the rear combination lamp 5.

On the other hand, a base 8 made of a synthetic resin material is disposed opposite to the back surface of the cover 7 and has a panel surface 8a forming a main portion thereof, and is formed in an annular shape along the periphery of the panel surface 8a. A thick portion 8b and a slit-like groove 8c formed in the thick portion 8b are provided. This groove 8c
As shown in a partially enlarged view of FIG. 3C, a flange 7c of the decorative cover 7 is fitted, and an adhesive 9 is filled in a gap between the flange 7c and the decorative cover 7 and the base 7 8 is air-tightly joined and integrated.

Conventionally, the panel surface 8a of the base 8 is generally formed as a parallel surface separated by a predetermined distance along the back surface of the panel surface 7a of the decorative cover 7 so as to conform to the shape of the panel 7a. Formed. However, in the embodiment of the present invention, as shown in FIG.
The panel surface 8a of the opposing base 8 itself is formed from a plurality of curved surfaces . Particularly in this embodiment , the base 8
The plurality of curved surfaces of the panel surface 8a extend in the longitudinal direction (vehicle width direction).
So as to form a groove or crest portion extending, thus, it is formed on the uneven surface, such as undulating in the vertical direction. others
The panel surface 8a of the base 8 and the panel surface 7 of the decorative cover 7
facing angle between a is you changes along the vertical direction.

Specifically, the curved surface forming the panel surface 8a is viewed in a longitudinal section, and upper and lower portions are respectively set as substantially flat surfaces 8v and 8w extending in parallel along the panel surface 7a, and the upper portion of the central portion is the panel surface. The concave surface 8x which is gentle and shallow with respect to 7a, the concave surface 8x which is shallow and deep with respect to 7a, and the concave surface 8y which is deep and narrow with respect to 7a.

The light guided to the back surface of the decorative cover 7 is condensed via the lens surface 7b and spreads inside the panel body 7a to give the decorative cover 7 a shine.

In other words, the light guided to the panel surface 8a of the base 8 is partially reflected in different directions depending on the curved surface, and illuminates the panel body 7a unevenly from the back surface side. As a result, the panel body 7a is illuminated with reflected light whose reflection direction has changed according to the shape of the curved surface of the panel surface 8a, and which has partially caused unevenness due to the difference in the reflection direction. In other words, the light shines in a state where the shadow is generated in a portion where the light amount is insufficient. In particular, according to the panel surface 8a having the curved surface structure as shown in FIG. 3A, since the groove (recess) formed by the curved surface extends in the vehicle width direction, the panel body 7a has the groove portion. Will result in a band-like shading along.

As a result, even with the decorative cover 7 (panel body 7a) having a uniform and smooth surface, the base surface 8a of the base 8 which is located at the inner part and is covered by the decorative cover 7 When the reflected light shines, a shadow is positively formed by the curved surface formed by the panel surface 8a, so that the decorative cover 7 can have a sense of depth (three-dimensional feeling) as a visual image. . That is, the decorative cover 7
Means that the entire area shines while forming the shadow area, and since the shadow area itself is positively formed in a predetermined portion, the depth that can visually recall the internal (back side) structure A feeling (thickness) can be given. If the structure of the tailgate garnish 6 provided with the decorative cover 7 that forms such a shadow, particularly a strip-shaped shadow in the vehicle width direction, is also applied to the structure of the combination lamp 5, the combination lamp 5 It is possible to construct a vehicle design that is continuous and integrated with the vehicle, that is, a visual image with a sense of connection. In particular, if the shadow line of the tailgate garnish 6 is a line having a connection including the design line 1a formed on the side surface of the side outer panel 1, the line extends continuously from the side surface of the vehicle to the rear portion. It is possible to construct vehicle designs with accent lines.

The mounting of the base 8 supporting the decorative cover 7 to the tailgate panel 2 is performed, for example, by attaching the base 8 to the back surface of the panel surface 8a of the base 8 as shown in FIGS. A clip 12 made of resin is inserted into the hook-shaped pedestal 11 provided, and the enlarged head of the clip 12 is inserted into a hole provided on the panel surface of the tailgate panel 2 while bending the enlarged head. Dish-shaped washer 1 attached to the base
3, the tailgate panel 2 may be sandwiched.

The tailgate / garnish employing the decorative panel structure characteristic of the present invention has been described above. However, it is of course possible to adopt the present invention as a front panel. Further, in the embodiment, the shading portion extending in the vehicle width direction is added. However, by changing the curved shape of the panel surface 8a of the base 8, a strip-shaped shading extending in a vertical direction or an oblique direction is formed, or an island shape is formed. Can be formed. The contrast of the shaded portion may be variably adjusted by setting the curvature of the curved surface, the color density of the paint forming the reflective surface, and the like according to the specifications. In addition, the present invention can be variously modified and implemented without departing from the gist thereof.
