JP5841863B2 - Alignment structure of vehicle headlamp and fender panel - Google Patents

Description

  The present invention relates to a structure for combining a headlamp and a fender panel of a vehicle, and more particularly to a structure for preventing a so-called whistling sound from being generated by a traveling wind.

  As a structure for preventing whistling sound generated from the vicinity of the gap between the headlamps, as disclosed in, for example, Patent Document 1, a step portion is formed on the outer peripheral edge portion of the lamp lens and a lens support portion of the housing is finely formed. It is common to suppress the resonance of air vibration by forming a rough surface and disturbing the wind.

Here, it is conceivable to prevent a whistling sound without providing a stepped portion or the like by providing a labyrinth structure at the joint portion between the lamp lens and the fender panel and reducing the suction flow velocity.

  When a rabilink structure is provided in the mating portion, the structure becomes complicated, the mold cost for molding becomes high, and there is a concern that the assembling property deteriorates.

  On the other hand, when the ends of the lamp lens and the fender panel are simply abutted with each other, it is necessary to provide a stepped portion in a wide range in order to avoid an increase in the suction flow velocity, and the appearance and productivity deteriorate. There's a problem.

  The present invention has been made in view of the above-described conventional situation, and employs a simple mating portion structure that does not employ a labyrinth structure, and can prevent whistling noise by providing a minimum necessary step portion. It is an object to provide a structure of a mating portion between a wing panel and a fender panel.

The present invention relates to a fender in which a combined portion of a lamp lens of a headlamp and a fender panel on a vehicle side portion has a lamp lens side wall portion in which the lamp lens is directed toward the vehicle inner side and a fender panel is directed toward the vehicle inner side. In the combined structure of the vehicle headlamp and the fender panel, which has a configuration in which the side wall portion faces substantially parallel,
The lamp lens has a bottom wall formed to bend and extend toward the rear side of the vehicle following the lamp lens side wall, and the lamp lens side wall extends the bottom wall toward the lamp lens side wall. A concave portion is formed, and a plurality of concave and convex portions are formed in the concave portion.

  According to the mating portion structure according to the present invention, the suction air sucked out from the gap between the lamp lens and the fender panel by the running wind swirls in the recess, and the flow is further disturbed by the uneven portion in the recess. Since the flow velocity is reduced, whistling noise can be prevented only by providing the necessary minimum unevenness even with a simple mating portion structure without a labyrinth structure.

  In addition, since it is only necessary to provide the concave portion and the concave and convex portion only in the concave portion, it is possible to avoid deterioration of appearance as in the case where the concave and convex portion is provided in a wide range.

It is a front perspective view of a vehicle front part provided with a headlamp to which a mating part structure according to an embodiment of the present invention is applied. FIG. 2 is a cross-sectional plan view around the headlamp in the vehicle (a cross-sectional view taken along line II-II in FIG. 1). It is an expanded sectional top view of the said fitting part structure. It is a perspective view which shows the said fitting part structure typically. It is an enlarged view for demonstrating the flow of the suction | inhalation wind of the said matching part structure.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  In the figure, reference numeral 1 denotes a front part of an automobile. The front part 1 is a left and right fender panel 2 constituting left and right side walls of an engine room, a bonnet 3 for opening and closing the engine room, and a front wall. And a front bumper 4 constituting the part. Headlamps 5 and 5 are arranged at the left and right corner portions of the vehicle front portion 1.

  The headlamp 5 includes a lamp lens 6, a lamp housing 7 that supports the lamp lens 6, a bulb 8 that is supported by the lamp housing 7 and protrudes toward the lamp lens 6, and a reflector that surrounds the bulb 8. 9.

  The abutting portion structure A of the lamp lens and the fender panel according to the embodiment of the present invention is applied to the abutting portion between the outer edge portion 6a of the lamp lens 6 and the front edge portion 2a of the fender panel 2.

  In the first-stage matching portion structure A, a lamp lens side wall portion 6b is integrally formed on the outer edge portion 6a of the lamp lens 6 so as to be directed toward the vehicle inner side, and the front edge portion 2a of the fender panel 2 is formed on the vehicle inner side side. The fender side wall portion 2b is integrally formed so as to be oriented, and the fender side wall portion 2b and the lamp lens side wall portion 6b face each other substantially in parallel and with a gap D therebetween.

  Further, a protrusion 6m is provided on the outer edge 6a of the lamp lens 6 so as to form an arc shape in a cross-sectional view. As shown by an arrow B in FIG. 4, the projection 6m is for allowing the traveling wind to flow away from the facing portion between the lamp lens side wall 6b and the fender side wall 2b.

  Furthermore, a bottom wall 6c is formed on the outer edge portion 6a of the lamp lens 6 so as to bend and extend toward the vehicle rear side following the lamp lens side wall portion 6b. A rear end 6d of the bottom wall 6c is supported by the lamp housing 7.

  A concave portion 6e is formed in a portion of the lamp lens side wall portion 6b on the bottom wall 6c side. The concave portion 6e includes an extension portion 6f obtained by extending the bottom wall 6c toward the lamp lens side wall portion 6b, and an inclined portion 6g extending inclined from the distal end of the extension portion 6f toward the lamp lens side wall portion 6b. In the cross-sectional view, it is formed in a triangular concave shape with the extension line 6b 'of the lamp lens side wall 6b.

  Further, the lamp lens 6 is formed with a concavo-convex portion 6h formed by arranging a large number of ridges extending in the front-rear direction in parallel in the vehicle width direction. The concavo-convex part 6h extends to the front part of the bottom wall 6c from the concave part 6e, the concave / convex part 6j formed in the concave part 6e, the side concavo-convex part 6i formed in the lamp lens side wall part 6b. It is comprised with the bottom uneven part 6k formed in this. In addition, since the said side uneven part 6i is formed to the inner side a little from the outer end surface of the lens side wall part 6b, it is hard to see from the outside.

  In the structure of the present embodiment, when the vehicle travels, a negative pressure is generated in the vicinity of the mating portion structure A by the traveling wind B flowing along the fender panel 2 from the headlamp 5, thereby causing the headlamp 5 and the fender panel 2 to move. Suction air C sucked out from the gap is generated.

  In this embodiment, the lamp lens side wall 6b is provided with a recess 6e, and the recess 6e is further provided with a concave / convex portion 6j. Therefore, the suction air C swirls in the recess 6e according to its shape and is recessed. Since the flow is further disturbed by the strip irregularities 6j and the flow velocity is lowered, the whistling sound can be effectively prevented. Further, the flow of the suction air C is also disturbed by the bottom uneven portion 6k and the side uneven portion 6i, and the flow velocity also decreases from this point.

  Furthermore, since the bottom uneven portion 6k of the bottom wall 6c extends from the recessed portion 6e to the rear of the vehicle and is constituted by a plurality of ridges extending linearly toward the recessed portion 6e, the suction air C is formed in the recessed portion 6e. From this point, the suction air C can easily be swirled, the flow can be disturbed, and the flow velocity can be reduced.

  Further, since the protrusion 6m is provided on the outer edge portion 6a of the lamp lens 6, the traveling wind flows away from the facing portion between the lamp lens side wall portion 6b and the fender side wall portion 2b, and the suction force can be reduced accordingly. .

Thus, in this embodiment, since the whistling sound can be prevented by a simple butting structure that does not require a labyrinth structure, the structure is not complicated.

  In the above embodiment, the concave and convex portions are also formed in the front portions of the lamp lens side wall portion 6b and the bottom wall 6c. However, in the present invention, the concave and convex portions may be provided at least in the concave portion 6e. In such a case, it is possible to suppress the generation of whistling noises only by providing the minimum necessary uneven portions, and it is possible to avoid the appearance deterioration as in the case where the uneven portions are provided in a wide range.

  Moreover, although the said Example demonstrated the case where an uneven | corrugated | grooved part was comprised with the several protruding item | line extended in a linear form, the uneven | corrugated | grooved part of this invention is not limited to this, For example, the dimple which provides a fine dent on the surface Anything that disturbs the wind is acceptable.
