  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide an exterior decorative part for an automobile that improves designability and reduces poor decoration on the design surface.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

[Application Example 1]
The exterior decoration part of the automobile of application example 1 is an exterior decoration member attached as an exterior to the surface of the automobile, and has a housing design portion having a smooth housing design surface toward the outside of the automobile. A transparent housing that is attached to the front of the housing so as to cover the housing, with a housing that is directly attached to the outer surface of the lens, and a projection that projects toward the housing on the rear surface of the lens design that faces the housing design surface Or a translucent lens member.

  According to the exterior decorative part of an automobile of Application Example 1, by projecting a protrusion toward the housing on the back of the lens design, light incident on the lens is refracted, and the shape of the protrusion is caused by light shading. Reflect. Designs that are more complex than those that are smooth can be expressed, and design properties can be improved. In addition, the shape of the protrusion can be reflected on the surface of the housing design, so that a more visually appealing appearance can be realized.

  In addition, since the housing design portion is substantially flat without providing a projection, there is no sinking or the like due to molding by the projection provided on the housing design portion when there is a housing mounting portion on the vehicle. The mounting part due to deformation is not affected. Further, since the deformation hardly occurs, even if the housing design surface is subjected to vapor deposition, sputtering, and plating, the occurrence of cracks and the like can be prevented particularly when the surface becomes glittering.

[Application Examples 2 and 3]
As application example 2, the design property can be improved by decorating the back surface of the lens design, such as plating or painting. Furthermore, as an application example 3, the housing design surface can be decorated such as plating or painting. Various designs can be expressed by decorating the back of the lens design, the surface of the housing design, or both. Moreover, since the decorated surface is not exposed to the outer surface by the lens member, it is possible to prevent peeling or decoration from being deteriorated or prevented due to the external environment or picking.

[Application Example 4]
By making the protrusion on the back of the lens design an asymmetrical shape with a substantially horizontal axis in the vertical section, the light refraction is different from the normal convex lens structure, and the reflection on the housing design surface is not uniform. Designs with varying shades can be realized.

FIG. 1 is a front view of an exterior decorative part of an automobile according to the present invention. FIG. 2 is a cross-sectional view taken along line AA of FIG.

  Hereinafter, an example of an exterior decorative part of an automobile will be described. FIG. 1 is a front view of an exterior decorative part of an automobile according to the present invention. The exterior decorative component 10 of this embodiment is a component that decorates the periphery of the radiator grille that is mounted on the entire surface of the automobile.

  The exterior decorative component 10 includes a housing 20 and a lens member 30 assembled in front of the housing 20. The housing 20 is attached so as to form an attachment portion (not shown) according to the shape on the vehicle side, and is arranged on the outer surface of the automobile using bolts if necessary. Furthermore, an ornament 40 is provided in the center.

  FIG. 2 is a cross-sectional view taken along the line A-A of FIG. The housing 20 is molded by injection molding using polypropylene (PP) and acrylonitrile / ethylene-propylene-diene / styrene (AES) which are rigid and have good moldability as a resin material. It has a housing design portion 21 that is flat and long in the horizontal direction. A smooth housing design surface 22 is formed in the housing design portion 21 toward the front. The housing design portion 21 may be molded using a colored resin material, and by appropriately selecting means such as vapor deposition, sputtering, plating, painting, or attaching a film to the housing design surface 22 to decorate it. It may be colored.

  The housing design portion 21 has a slightly convex shape on the entire front side of the vehicle, and has a U-shaped connection that opens toward the front of the vehicle and protrudes slightly upward at the rear of the vehicle at the upper and lower ends of the outer periphery. Recesses 23a and 23b are formed. The connection recesses 23a and 23b are portions to be joined to a lens member 30 described later. The direction and shape of the connection recesses 23a and 23b may be changed depending on the design and the mounting structure on the vehicle side.

  Next, the lens member 30 will be described. As shown in FIG. 2, the lens member 30 is formed by injection molding with highly transparent acrylic (PMMA) or polycarbonate (PC) as a resin material, and is disposed in front of the housing 20. In the present embodiment, the lens design portion 31 that forms the design of the lens member 30 has a shape that is slightly separated from and parallel to the shape of the housing design portion 21.

  The lens design portion 31 has a lens design surface 32 on the front side of the vehicle and a lens design back surface 33 facing the housing design surface 22 on the vehicle rear side. A projection 34 is formed on the lens design portion 31 and the lens design back surface 33 toward the housing design surface 22. In the present embodiment, two protrusions 34 are provided in cross section.

  Although not shown, the protrusion 34 is formed in the horizontal direction along the shape of the exterior decorative component 10 in a front view of the exterior decorative component 10. As a cross-sectional shape, the protrusion 34 includes a vertex 34a close to the housing design part 21, a first hem 34b corresponding to the hem of the protrusion 34 on the upper side, and a second hem corresponding to the hem of the protrusion 34a on the lower side. 34c. A first distance W1 from the axis passing through the apex 34a in a direction substantially perpendicular to the vertical direction (vertical direction) of the lens design portion 31 on which the protrusion 34 is formed, and a second skirt 34c. The relationship of the second distance W2 is W1 <W2, and the first skirt 34b and the second skirt 34c side are asymmetrical from the axis passing through the vertex.

  By providing the projection 34 on the lens design back surface 33, it is possible to realize a design that is refracted and reflected by the light incident on the housing design surface 22 and has depth and shade. Furthermore, since the projection 34 is asymmetrical, incident light is not uniformly refracted, so that shades of shading that differ from each other corresponding to the shape from the apex 34a to the first skirt 34b and the second skirt 34c. Can be reflected, and the design can be further improved. In addition, since the protrusions 34 are not provided on the housing 20, deformation during molding of the housing 20 to a mounting portion (not shown) on the vehicle body is reduced.

  As for the assembly of the lens member 30 to the housing 20, connection end portions 35 a and 35 b bent from the lens design portion 31 toward the housing 20 are inserted into the connection recesses 23 a and 23 b of the housing 20, respectively, and are heat-welded and integrated. It becomes. As a means for heat welding, a means having an appropriate shape such as hot plate welding, laser welding, ultrasonic welding or the like can be used. In order not to visually recognize the gap between the connection end portions 35a and 35b and the connection recess portions 23a and 23b, outer peripheral protrusions 36a and 36b are provided in front of the connection recess portions 23a and 23b on the outer periphery side of the connection end portions 35a and 35b. Yes. Further, the outer peripheral projections 36a and 36b can prevent dust and dirt from entering the connection recesses 23a and 23b.

  The decoration of the lens member 30 will be described. The lens member 30 may be in a transparent state, but can be decorated by appropriately selecting means such as vapor deposition, sputtering, plating, painting, or attaching a film to the lens design back surface 33. The translucent lens member 30 may be molded by molding a resin material obtained by coloring the resin material of the lens member 30.

  The configuration can be changed as appropriate without departing from the gist of the present invention described above. For example, in the above-described configuration, the housing design surface 22 and the lens design back surface 33 may each be made of a colored material, or may be decorated to improve the design in color. Both the housing design surface 22 and the lens design back surface 33 may be decorated.

  In the present embodiment, the radiator grille in front of the automobile has been described, but it can also be used as an ornament, regardless of the size of an exterior decorative part attached to the back panel.
