Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a light-emitting front grill for an automobile, in which part or all of the front grill that decorates the radiator is made of a light-transmitting resin that emits light. It is.

[Problems that conventional technology and ideas try to solve]

Conventional grills of this type have been difficult to construct at low cost because they are based on the premise that an auxiliary light source is provided that illuminates the inside of the translucent resin panel from behind.

In view of this point, it is an object of the present invention to provide a light-emitting front grille for an automobile that enables light-emitting decoration without the need for a dedicated light source.

[Means for solving problems]

In order to achieve this object, the present invention forms a side part 12 that is inclined inward toward the outside of the vehicle interior at the end of the translucent resin panel 11 toward the outside of the vehicle interior, and also forms an edge of this side part. 12a is brought into close contact with the outer surface of the end of the front lens 1a of the headlamp 1 in the direction toward the vehicle interior, and the light enters the inner surface of the resin panel 11 from the edge 12a to form the side inclined surface 12b or the outer surface 1 of the resin panel 11.
A light reflecting surface 13 was formed to reflect forward the incident light that was refracted inside at 1b.

[Effect]

When the headlamp 1 is turned on at night, the edge light enters from the edge 12a of the resin panel 11 and is emitted from the front, and the side slope 1
2b or the resin panel outer surface 11b and the optical axis refracted inward and directed toward the inner surface is directly or multiple reflected by the light reflecting surface 13, thereby causing the resin panel 11 to emit light.

[Example of idea]

1 and 2 show the structure of a light-emitting front grille 10 according to an embodiment of the present invention.

This front grill is composed of a rectangular resin panel 11 having a striped pattern 11a formed on its surface, and has an inward side portion 12 formed around the periphery (second
figure). The side portion 12 on the side of the headlamp 1 is sloped outward in consideration of the deflection characteristics for incident light (FIG. 1). Also, this oblique side 12
The edge 12a of the front lens 1 of the headlamp 1
It is in close contact with the outer surface of the end of a toward the outside of the vehicle interior. A cut portion 13 is formed on the inner surface of the resin panel 11 to reflect light incident from the side forward.

Such a front grill 10 is also provided on the opposite side of the radiator 2.

When the headlamp 1 is turned on, the edge light A enters the edge 12a of the resin panel 11, and depending on the angle of incidence, some of it passes through the resin panel 11 and is emitted directly forward without being reflected. Further, a part is refracted inward by the side inclined surface 12b or the outer surface 11b. At this time, the presence of the cut portion 13 on the inner surface of the resin panel 11 allows the edge light A to be
is reflected once or multiple times and becomes forward emitted light, which together with the above-mentioned direct emitted light, hits the resin panel 1.
1 to emit light.

Note that the inner surface of the resin panel 11 may be treated with a satin finish. Various patterns can be formed on the surface of the resin panel and created using light. Furthermore, although the light-emitting front grille 10 of the above-mentioned embodiment is arranged on both sides of the radiator 2, it is also possible to arrange a resin panel molded in a lattice shape also in front of the radiator to make the entire radiator grille a light-emitting type. You can also do it.

[Effect of idea]

As described above, according to the present invention, the illuminating decoration of the radiator grille can be realized with a simple structure and in a cost-effective manner by utilizing the headlight light of a normal headlamp, without providing a dedicated lamp.
