Description

  The present invention relates to a vehicle exterior component attached to a vehicle.

  Conventionally, vehicle exterior parts such as a bumper garnish are attached to the bumper in order to improve the decorativeness of a bumper or the like constituting a part of the vehicle body. This vehicle exterior component includes an exterior component body having an adhesive surface (outer peripheral edge) provided on the back surface side, and a long lip member bonded along the adhesive surface.

  Specifically, as shown in FIGS. 7B and 7C, the lip member 100 is interposed between the bonding surface 210 of the exterior component body 200 and the bumper 300 and bonded to the bonding surface 210. Main body 110 and a close contact portion 120 that extends from the end of the main body portion 110 toward the vehicle side and is in close contact with the bumper 300 (see, for example, Patent Document 1).

  Such a lip member 100 is adhered between the adhesive surface 210 of the exterior component main body 200 and the bumper 300 by an adhesive tape or the like, and contact (interference) between the exterior component main body 200 and the bumper 300 is prevented.

JP 2008-44461 A

  By the way, in recent years, from the viewpoint of design and the like, the adhesive surface 210 of the exterior component main body 200 has a linear portion 211, an outwardly curved portion 212 that curves outward, and an inside, as shown in FIG. A curved inwardly curved portion 213 is provided.

  When attaching the above-described lip member 100 to such an adhesive surface 210, it is necessary to attach along the outward curved portion 212 and the inwardly curved portion 213 from the straight portion 211. At this time, the stress applied to the contact portion 120 of the lip member 100 located at the outward curved portion 212 is different from the stress applied to the contact portion 120 of the lip member 100 located at the inward curved portion 213.

  For this reason, as shown in FIG. 7B, the close contact portion 120 falls to the bumper 300 side in the outward curved portion 212, and the close contact portion 120 and the bumper 300 in the inward curved portion 213 as shown in FIG. Will fall to the other side. Therefore, the inwardly curved portion 213 has a problem that the adhesion between the close contact portion 120 and the bumper 300 is lower than that of the outwardly curved portion 212.

  Accordingly, an object of the present invention is to provide an exterior part for a vehicle that can suppress a decrease in adhesion between a part of a vehicle such as a bumper and an adhesion part of a lip member located at an inwardly curved part.

In order to solve the above-described problems, the present invention has the following features. First, the first feature of the present invention is that it is attached so as to face the vehicle (vehicle C), and a straight portion (first straight portion 31 and second straight portion 32) and a curved portion (inward curved portion) that curves inward. 34) an exterior component main body (exterior component main body 10) provided with an adhesive surface (adhesive surface 30) on the back surface side, a main body portion (main body portion 21) bonded along the adhesive surface, and the main body A vehicle exterior component (vehicle exterior) including a long lip member (lip member 20) that extends from an end of the portion and has a contact portion (contact portion 22) that is in close contact with the vehicle when mounted on the vehicle. In the component 1), the adhesive surface located at the curved portion is formed by an inclined surface (inclined surface 35) with the contact portion side protruding toward the vehicle side, and the inclined surface is curved from the straight portion to the curved portion. Transition area to migrate to a part A transition region 35A, the 35B), the transition region is summarized as Rukoto formed by gradually changing toward the curved portion from the straight portion.

According to this feature, the adhesive surface located at the curved portion is formed by an inclined surface. That is, the lip member attached to the adhesive surface is attached to an inclined surface as an adhesive surface located at the curved portion. Thereby, it can prevent that the contact part of the lip member located in a curved part falls down on the opposite side to a vehicle. For this reason, the fall of the adhesiveness of the contact part of a lip member and a part of vehicle can be suppressed. In particular, the transition region is formed by gradually changing from a straight part to a curved part. For example, the transition region is formed so as to gradually increase from the straight portion to the curved portion. Thereby, the lip member passes through the transition region gently inclined from the straight portion and is attached to the inclined surface. For this reason, the lip member can be attached to the exterior component body without the meandering of the lip member over the entire length of the adhesive surface, compared to the case where the lip member is attached to an inclined surface where the lip member rapidly increases, and the appearance visibility is improved. Will improve. Moreover, it can prevent that a clearance gap produces between a lip member and an adhesion surface, and can prevent that the adhesiveness of the contact part of the lip member located in an inward curve part and a part of vehicle becomes non-uniform | heterogenous.

  A second feature of the present invention is the vehicle exterior component according to the first feature of the present invention, wherein the inclined surface is formed higher on the vehicle side than the adhesive surface located at the linear portion. This is the gist.

  According to this feature, the inclined surface is formed higher on the vehicle side than the adhesive surface located in the straight line portion. Thereby, compared with the case where an inclined surface is formed lower than the adhesion surface located in a linear part, the contact part of the lip member located in an inward curved part becomes closer to the vehicle side. For this reason, the adhesiveness of the contact part of the lip member located in an inwardly curved part and a part of vehicle can be improved.

A third feature of the present invention is the vehicle exterior component according to the first or second feature of the present invention, wherein the body portion corresponds to at least the curved portion and is opposite to the contact portion. The gist is that a cut is formed at the location.

  According to this feature, a cut is formed at least at a location on the main body portion corresponding to the curved portion and on the side opposite to the contact portion. As a result, when attaching the lip member to the adhesive surface, it becomes easier to follow the shape of the curved portion, so that it is ensured that the adhesion between the close contact portion of the lip member located in the curved portion and a part of the vehicle is not uniform. Can be prevented. In addition, as the lip member easily follows the shape of the curved portion, the work of attaching the lip member to the bonding surface is facilitated.

  According to the features of the present invention, it is possible to provide a vehicle exterior component that can suppress a decrease in adhesion between a part of a vehicle such as a bumper and an adhesion part of a lip member located at an inwardly curved portion.

(4) Action / Effect In the present embodiment described above, the adhesive surface 30 located on the inwardly curved portion 34 is formed by the inclined surface 35. That is, the lip member 20 attached to the adhesive surface 30 is attached to the inclined surface 35 as the adhesive surface 30 located at the inwardly curved portion 34. Thereby, it can prevent that the contact | adherence part 22 of the lip member 20 located in the inward curved part 34 falls down on the opposite side to the rear bumper RB. For this reason, the fall of the adhesiveness of the contact part 22 of the lip member 20 and the rear bumper RB can be suppressed.

  In the present embodiment, the inclined surface 35 is formed higher on the rear bumper RB side than the adhesive surface 30 located on the second linear portion 32 adjacent to the inwardly curved portion 34 and the outwardly curved portion 33. Thereby, compared with the case where the inclined surface 35 is formed lower than the bonding surface 30 in the other region, the close contact portion 22 of the lip member 20 located at the inwardly curved portion 34 becomes easier to approach the rear bumper RB side. For this reason, the adhesiveness of the contact | adherence part 22 of the lip member 20 located in the inward curved part 34, and the rear bumper RB can be improved.

  In the present embodiment, the transition regions 35 </ b> A and 35 </ b> B are formed so as to gradually increase from the second straight portion 32 adjacent to the inwardly curved portion 34 and the outwardly curved portion 33 to the inwardly curved portion 34. Accordingly, the lip member 20 is attached to the inclined surface 35 through the transition regions 35A and 35B which are gently inclined from the outward curved portion 33. For this reason, the lip member 20 is attached to the exterior component main body 10 without the lip member 20 meandering over the entire length of the adhesive surface 30 as compared with the case where the lip member 20 is attached to the inclined surface 35 where the lip member 20 suddenly increases. And appearance visibility is improved. Further, it is possible to prevent a gap from being generated between the lip member 20 and the adhesive surface 30, and the adhesion between the contact portion 22 of the lip member 20 located at the inwardly curved portion 34 and the rear bumper RB becomes uneven. Can be prevented.

  In the present embodiment, a cut 21 </ b> A is formed at least on the main body 21 corresponding to the inwardly curved portion 34 and on the side opposite to the contact portion 22. Accordingly, when attaching the lip member 20 to the adhesive surface 30, it becomes easy to follow the shape of the inwardly curved portion 34, and therefore, the adhesion between the close contact portion 22 of the lip member 20 located on the inwardly curved portion 34 and the rear bumper RB is improved. Non-uniformity can be reliably prevented. In addition, as the lip member 20 easily follows the shape of the inwardly curved portion 34, the work of attaching the lip member 20 to the adhesive surface 30 is facilitated.
