[0011]
According to the fourth aspect of the present invention, the portion of the rib that is exposed from the outermost edge of the lamp lens to the outside of the vehicle is only the front end substantially perpendicular to the vehicle body panel. It is possible to prevent the appearance of the gap from being deteriorated by the ribs exposed from the side.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an end view (an end view taken along line 1-1 in FIG. 3) showing an embodiment of a vehicle lamp structure of the present invention.
The lamp according to the present embodiment exemplifies a lamp 20 attached to a trunk lid 12 of a rear combination lamp 10.
[0013]
In a portion where the lamp 20 is disposed, a trunk lid outer 14 (body outer panel) forming the outer shape of the trunk lid 12 and a lamp mounting panel 16 joined to a flange 14a folded inside the trunk lid outer 14 are provided. The vehicle body panel 18 is formed, and a recess 18a is formed by the flange 14a and the lamp mounting panel 16.
[0014]
The lamp 20 is fitted into the recess 18a and mounted on the lamp mounting panel 16, a lamp lens 24 for covering an opening 22a on the vehicle exterior side of the housing 22, and a bulb surrounded by the housing 22 and the lamp lens 24. 26.
A groove 22b having a substantially U-shaped cross section which is open to the outside of the vehicle is formed in a peripheral portion of the housing 22. A peripheral edge 24a of the lamp lens 24 is inserted into the groove 22b, and the bottom of the groove 22b is filled. A peripheral edge 24 a of the lamp lens 24 is joined to the housing 22 via a sealant 28.
[0015]
Further, a rib 30 is formed on at least a predetermined portion of the peripheral portion of the housing 22 so as to be elastically contactable with the vehicle body panel 18 surrounding the peripheral portion of the housing 22. For example, as shown in FIG. 3, a rib 30 is provided at each of the portions 34, 34 of the lamp body 20 where the vehicle body panel 18 substantially opposes each other at the mounting reference point 32 set at a substantially middle position in the vertical direction of the lamp 20. Provided.
[0016]
The rib 30 has a base 30a extending linearly toward the vehicle body panel 18 continuously from the bottom wall 22c of the groove 22b having a substantially U-shaped cross section, and is bent from the base 30a to be substantially parallel to the vehicle body panel 18. And a tip portion 30c that is bent from the extension portion 30b and extends toward the vehicle body panel 18 and substantially perpendicular to the vehicle body panel 18 in a crank shape. I have. The extension 30b extends to the vicinity of the flange 14a of the outer trunk lid 14, and the distal end 30c is elastically contactable with the flange 14a.
[0017]
When the lamp 20 configured as described above is mounted on the vehicle body panel, the housing 22 is mounted on the vehicle body panel 18 at a mounting point 36 provided at a predetermined position with reference to the mounting reference point 32. At this time, if the gap between the vehicle body panel 18 and the lamp 20 shifts in a direction to become narrower, the rib 30 elastically contacts the vehicle body panel 18 to prevent the lamp 20 from approaching the vehicle body panel 18. Thus, by adjusting the lamp 20 to a position where the upper and lower ribs 30 do not abut the vehicle body panel 18, the lamp 20 can be mounted at a correct position.
[0018]
As shown in FIG. 2, when the rib 30 elastically contacts the vehicle body panel 18, the force applied to the rib 30 is determined by the crank-like shape of the rib 30 including the tip 30 c, the extension 30 b, and the base 30 a. By elastically deforming, the rib 30 itself can absorb it. Further, since the base 30a of the rib 30 extends linearly continuously from the bottom wall 22c of the groove 22b toward the vehicle body panel 18, the force from the rib 30 is applied along the wall surface of the bottom wall 22c of the groove 22b. The groove 22b is hardly deformed because it is transmitted to the housing 22 and not to the side wall of the groove 22b. Accordingly, the sealant 28 does not peel off, and does not affect the sealing performance.
[0019]
Further, the rib 30 has a front end portion 30c which is opposed to the flange 14a of the trunk lid outer 14 of the vehicle body panel 18 even though the base portion 30a faces the lamp mounting panel 30a of the vehicle body panel 18. By being resilient, positioning with respect to the trunk lid outer 14 which forms the outer shape of the trunk lid 12 can be performed, so that the position of the lamp 20 which is good in appearance can be determined.
[0020]
Further, the tip 30c of the rib 30 exposed from the gap between the outermost edge of the lamp lens 24 and the trunk lid outer 14 has a shape extending substantially perpendicularly to the flange 14a, so that the rib 30 exposed from this gap looks good. Can be prevented from becoming worse.
FIG. 4 shows another embodiment according to the present invention, in which the distal end portion 30c of the rib 30 is always resilient to the trunk lid outer 14 at the substantially opposed portions 34, 34 of the vehicle body panel 18 even after the mounting. It differs from the embodiment of FIG. 1 in the point of contact, and the other configuration is the same.
[0021]
As described above, since the ribs 30 always hold the housing 22 with respect to the vehicle body panel 18, the gap between the housing 22 and the vehicle body panel 18 is made as uniform as possible in the substantially opposite portions 34, 34 of the vehicle body panel 18. Can be.
Further, since the distal end portion 30c of the rib 30 makes elastic contact with the flange 14a of the trunk lid outer 14 of the vehicle body panel 18, the positioning can be performed with respect to the trunk lid outer 14, which forms the outer shape of the trunk lid 12, so that the appearance is improved. A good position of the lamp 20 will be determined.
[0022]
In the above embodiment, the ribs 30 in the substantially opposed portions 34, 34 of the vehicle body panel 18 have been described. However, the ribs 30 may be provided over substantially the entire peripheral surface of the housing 22. The effect is obtained.
