Description

  The present invention relates to grill illumination in which indirect lighting is applied to a front grill of a vehicle.

  At the front end of the vehicle, a front grill having an opening for ventilation is disposed. Conventionally, it has been proposed to apply indirect lighting to the front grille. For example, Patent Document 1 describes that light is emitted from a lighting device disposed along the outer edge of the front grille toward the front (front) of the front grille. By irradiating the front surface of the front grille with light in this way, it is possible to make the pattern according to the shape of the frame part float up by the shadow created by the above-mentioned opening part and the frame part that borders it. Design can be improved.

  By the way, when a vehicle such as a truck is viewed from the front (in the front view of the vehicle), various parts such as piping, wiring and chassis related parts disposed in the engine room behind (rear side) through the opening of the front grille The members become visible. For this reason, when the front grille is formed with an opening portion more than necessary, the appearance of the vehicle in a front view may be degraded. In particular, when light is emitted toward the front of the front grille as described above, the light may strike the members disposed behind the front grille, which may cause a problem that these members are easily visible.

  With respect to this problem, temporarily taking measures to close the opening described above, although the members behind the front grille can not be seen, the air permeability of the front grille is impaired. In addition, if a measure is taken to omit the indirect lighting, although the member behind the front grille becomes difficult to see, the design can be deteriorated because the pattern can not be raised by shading.

  The grill illumination of the present invention is devised in view of the problems as described above, and has an object to improve the design while suppressing the decrease in the air permeability of the front grille.

  The grille illumination disclosed herein is disposed at the front end of the vehicle and has a plurality of openings for ventilation and a frame that borders the opening, and a decorative pattern is formed by the opening and the frame. And a front grille having a recess of the same shape as the opening and a protrusion projecting toward the front of the vehicle from the periphery of the recess, the front grill forming the decorative pattern with the recess and the protrusion. And a light source for emitting light toward the front surface of the frame and the convex portion of the front grille.

  Thereby, in the front grille, air permeability is secured in the area where the opening is formed, and in the area where the recess is formed, the rear member can not be seen visually, and the appearance is improved. Further, due to the light from the light source, in front view of the vehicle, the pattern appears to rise along the frame portion and the convex portion.

  According to the disclosed grille illumination, the design can be improved while suppressing the decrease in the air permeability of the front grille.

(A) is an AA arrow sectional view of FIG. 2, (B) is a BB arrow sectional view of FIG. 2. It is a figure for demonstrating the effect | action of grill illumination, (A), (B) is the same sectional drawing as FIG. 3 (A), (B), respectively.

  A grill illumination as an embodiment will be described with reference to the drawings. The embodiments shown below are merely illustrative, and there is no intention to exclude the application of various modifications and techniques that are not specified in the following embodiments. Each structure of this embodiment can be variously modified and implemented in the range which does not deviate from those meaning. Also, they can be selected as needed or can be combined as appropriate.

[1. Constitution]
The grille illumination 1 according to the present embodiment is applied to a vehicle 10 shown in FIG. Here, a truck is illustrated as the vehicle 10. The grille illumination 1 has a function of introducing outside air into an engine room formed at the rear thereof and a function of decorating the front (front) of the vehicle 10.

  As shown in FIG. 2, the grille illumination 1 includes a front grill 2 having a plurality of openings 4 for ventilation and a light source 3 for decorating the front grill 2 with light. The front grille 2 is a panel member disposed at the front end of the vehicle 10, and extends along the vehicle width direction and the vertical direction. The front grille 2 is made of, for example, a resin, and its rear surface (rear surface) is black. The front grille 2 is located in front of the engine room of the vehicle 10. Therefore, on the rear of the front grille 2, various members such as piping, wiring and chassis related parts disposed in the engine room are provided.

  The front grille 2 has the opening 4 described above and a frame 5 for bordering the opening 4, and the opening 4 and the frame 5 form a predetermined decorative pattern. The front grille 2 of the present embodiment has a honeycomb decorative pattern by the opening 4 and the frame 5. That is, the front grille 2 is provided with a large number of hexagonal openings 4 regularly arranged.

  Further, the front grille 2 has a concave portion 6 having the same shape as the opening 4 and a convex portion 7 protruding forward from the peripheral edge of the concave portion 6. It forms so that the same decorative pattern as the decorative pattern which the opening part 4 and the frame part 5 mentioned above make may be made. Specifically, the recesses 6 are hexagonal, and are regularly arranged in the front grille 2 so as to form a honeycomb-shaped decorative pattern with the protrusions 7.

  The opening 4 and the frame 5 are formed in a predetermined first region R1 including the center of the front grille 2 in the vehicle width direction (left and right direction). On the other hand, the concave portion 6 and the convex portion 7 are formed in the second region R2 provided on the left and right sides of the first region R1. In addition, in this embodiment, the case where front grille 2 is made into left-right symmetric shape is illustrated.

  As shown to FIG. 3 (A), in the vertical cross section of the front grill 2, it is the shape which protruded the frame part 5 forward as it goes below. That is, in the cross section shown in FIG. 3A, the second point 5b is located forward in the first point 5a of the frame 5 and the second point 5b located below the first point 5a. The shape of the frame 5 is set as follows. By setting the shape of the frame 5 as described above, it is possible to apply the light emitted from above to the frame 5 to the entire frame 5.

  The same shape setting as that of the frame 5 is applied to the convex 7 as well. Specifically, as shown in FIG. 3B, the vertical cross section of the front grille 2 has a shape in which the convex portion 7 protrudes forward as it goes downward. That is, in the cross section shown in FIG. 3B, the second point 7b is located forward in the first point 7a of the convex portion 7 and the second point 7b located below the first point 7a. The shape of the convex portion 7 is set as follows. Thereby, it becomes possible to irradiate the light irradiated from above with respect to the convex part 7 on the whole convex part 7.

  The amount of protrusion of the protrusion 7 with respect to the recess 6 is reduced as it goes to the outer side in the vehicle width direction. In other words, the front grille 2 has a shape in which the second region R2 is flattened toward the outside in the vehicle width direction.

  In the upper part of 1st area | region R1 of the front grille 2, and 2nd area | region R2, the bulging part 8 for arrange | positioning the light source 3 is formed. The bulging portion 8 is a portion having a shape bulging forward, and is extended in the vehicle width direction. Slit 8b for letting the light of light source 3 pass toward first region R1 and second region R2 in lower wall portion 8a facing first region R1 and second region R2 of bulging portion 8 Is formed. In the present embodiment, two slits 8b are provided side by side in the vehicle width direction, and each slit 8b is extended in the vehicle width direction. The two slits 8b are formed to have a length that covers substantially the entire region in the vehicle width direction of the first region R1 and the second region R2.

  The light source 3 is a rod-like illumination device in which the bracket 3a is integrated, and is formed of, for example, an LED (light emitting diode). In the present embodiment, two light sources 3 are provided along the two slits 8 b respectively. Each light source 3 is disposed in the bulging portion 8 of the front grille 2 (above the wall portion 8a), and from the plurality of fixtures 9 (see FIGS. 2 and 3A and 3B), the front grille 2 is It is fixed. The two light sources 3 are formed to have a length that covers substantially the entire area in the vehicle width direction of the first area R1 and the second area R2, as in the slit 8b.

  The light source 3 emits light from above toward the front surface (front surface) of the frame 5 and the convex portion 7 of the front grille 2. As shown by broken lines in FIGS. 4A and 4B, the light from the light source 3 is guided downward through the slits 8b of the front grille 2 and strikes the frame portion 5 and the convex portion 7 to be reflected forward. Thereby, in front view of the vehicle 10, a pattern along the frame 5 and the convex portion 7 (that is, a honeycomb pattern in the present embodiment) appears bright and floating.

[2. effect]
(1) The front grille 2 has the opening 4 and the frame 5 having a decorative pattern, and the concave 6 and the convex 7 having the same decorative pattern as the decorative pattern of the opening 4 and the frame 5. Provided. Therefore, in the front grille 2, air permeability can be secured in the first region R1 in which the opening 4 and the frame 5 are formed, and in the second region R2 in which the recess 6 and the protrusion 7 are formed The components in the engine compartment of the vehicle can be made invisible from the front of the vehicle 10.

  Further, since the same decorative pattern is provided in the first region R1 in which the opening 4 is provided and the second region R2 in which the recess 6 is provided, the appearance of the front grill 2 can be enhanced. Furthermore, since light is emitted toward the front of the frame 5 and the convex 7 by the light source 3, the pattern along the frame 5 and the convex 7 can be raised. That is, when the vehicle 10 is viewed from the front, the decorative pattern unified over the first area R1 and the second area R2 of the front grille 2 can be raised by the indirect illumination of the light source 3. Therefore, according to the grille illumination 1 described above, it is possible to enhance the design while suppressing the decrease in the air permeability of the front grille 2.

  (2) Since the second region R2 of the front grille 2 is flattened toward the outside in the vehicle width direction, it is possible to generate gradation in the decorative pattern along the vehicle width direction. Thus, the design of the front grille 2 can be further enhanced.

  (3) Since the rear face of the front grille 2 is black, reflection of light from the light source 3 can be suppressed on the rear face of the front grille 2. This makes it difficult for the light to hit the members in the engine room, so that when the front grill 2 is viewed from the front of the vehicle 10, the members in the engine room can be made less visible. Thus, the appearance of the vehicle 10 can be improved.

[3. Modified example]
The shape of the front grille 2 shown in the present embodiment is an example. The front grille 2 may not have a symmetrical shape, and the decorative pattern provided by the frame 5 and the convex portion 7 may not have a honeycomb shape.

  The color of the light emitted by the light source 3 is not particularly limited. The light source 3 may emit, for example, monochromatic light, or may emit light of a plurality of colors for each region in the vehicle width direction (or temporally).

  The position of the light source 3 may be a position at which light can be emitted to the front surface of the frame 5 and the convex portion 7 of the front grille 2. Moreover, the direction which irradiates light from the light source 3 is not limited to the direction mentioned above. For example, the light source 3 may be disposed below the first region R1 and the second region R2 of the front grille 2, and light may be emitted from the lower side toward the front surface of the frame 5 and the convex portion 7. In this case, in order to direct the light from the light source 3 to the whole of the frame 5 and the convex 7, in the vertical cross section of the front grille 2, the frame 5 and the convex 7 move forward as they move upward. The shapes of the frame portion 5 and the convex portion 7 may be set so as to protrude.
