Description

  The present invention relates to a side sill garnish mounting structure.

A side sill garnish is attached to the outside of the side sill in the vehicle width direction mainly for the purpose of improving aerodynamic characteristics and design in a vehicle. Such a conventional mounting structure of a side sill garnish is such that the side sill garnish is directly fixed to a side sill outer that constitutes the outer side in the vehicle width direction of the side sill that is a vehicle body frame (see, for example, Patent Document 1).
JP 2003-95150 A

  In order to fix the side sill garnish directly to the side sill outer as described above, a plurality of clip mounting holes must be formed in the side sill outer. By the way, forming a hole in the side sill outer is not preferable for rust prevention. That is, it is preferable to reduce the number of holes formed in the side sill outer as much as possible.

  Therefore, an object of the present invention is to provide a side sill garnish mounting structure that can reduce the number of holes formed in the side sill outer.

  In order to achieve the above object, according to the first aspect of the present invention, a separate bracket (for example, the bracket 70 in the embodiment) is welded to the outside in the vehicle width direction of the side sill outer (for example, the side sill outer 60 in the embodiment). A side sill garnish (for example, side sill garnish 80 in the embodiment) is attached to the bracket.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the bracket extends to a pillar component of the side sill outer (for example, the pillar components 86, 87 in the embodiment).

  The invention according to claim 3 is characterized in that, in the invention according to claim 2, the bracket extends to the pillar constituent portions on both sides in the longitudinal direction of the vehicle body.

  According to the first aspect of the present invention, a separate bracket is welded to the outer side of the side sill outer in the vehicle width direction, and the side sill garnish is attached to the bracket. There is no need to do it. Therefore, the number of mounting holes formed in the side sill outer can be reduced, which is more preferable for rust prevention.

  According to the second aspect of the present invention, since the bracket extends to the pillar component portion of the side sill outer, it is possible to effectively reduce the strength weak portion at the base of the pillar component portion without increasing the plate thickness of the side sill outer. Can be reinforced. Therefore, the side sill outer can be reinforced while suppressing an increase in weight.

  According to the invention of claim 3, since the bracket extends to the pillar component portions on both sides in the vehicle longitudinal direction of the side sill outer, the strength of the base of both pillar component portions is not increased without increasing the plate thickness of the side sill outer. The weak part can be effectively reinforced. Therefore, the side sill outer can be reliably reinforced while suppressing an increase in weight.

  Here, as shown in FIG. 4, the side sill outer 60 extends in the longitudinal direction of the vehicle body to constitute the side sill 25, and the side sill constituting portion 85 extends upward from the side sill constituting portion 85 to constitute the center pillar 20. The structure includes a component 86 and a pillar component 87 that configures the rear quarter pillar 22 by extending upward from the rear side in the vehicle longitudinal direction with respect to the pillar component 86 of the side sill component 85. And the bracket 70 of 1st Embodiment is attached to the range between the pillar structure part 86 and the pillar structure part 87 of the side sill structure part 85. As shown in FIG. A mounting hole 89 for fitting a resin clip 82 attached to the side sill garnish 80 is formed at a position where the bracket 70 of the side sill outer 60 is not provided. Further, a mounting hole 90 for fitting a resin clip 82 attached to the side sill garnish 80 is also formed in the plate portion 42 of the side sill inner lower 40 shown in FIG. That is, the front side of the side sill garnish 80 is attached to the attachment hole 89 of the side sill outer 60 with the clip 82, the rear part is attached to the attachment hole 81 of the bracket 70 with the clip 82, and the lower part is the plate of the side sill inner lower 40. It is attached to the attachment hole 90 of the part 42.

  According to the first embodiment described above, the separate bracket 70 is welded to the outside of the side sill outer 60 in the vehicle width direction, and the side sill garnish 80 is attached to the bracket 70. There is no need to form a mounting hole for the side sill garnish 80 in the side sill outer 60. Therefore, the number of mounting holes 89 formed in the side sill outer 60 can be reduced, which is more preferable for rust prevention.

  Next, a side sill garnish mounting structure according to a second embodiment of the present invention will be described below mainly with reference to FIG. 5 with a focus on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the part similar to 1st Embodiment, and the description is abbreviate | omitted.

  In 1st Embodiment, although the bracket 70 was attached to the range between the pillar structure part 86 and the pillar structure part 87 of the side sill structure part 85, in 2nd Embodiment, the bracket 70 has side sill structure. It extends from the portion 85 to both pillar constituting portions 86 and 87.

  That is, in the bracket 70, the flange portion 71 fixed to the flange portion 61 of the side sill outer 60 extends to the pillar constituting portion 86 on the other side of the vehicle body and extends upward to the edge portion on the opening 19 side of the pillar constituting portion 86. On the other hand, the flange portion 71 extends to the pillar component 87 on the rear side of the vehicle body and extends upward to be welded to the edge of the pillar component 87 on the opening 19 side.

  In addition, the bracket 70 has plate portions 72 to 74 and a flange portion 75 on the other hand extending to the lower side of the pillar constituting portion 86 on the front side of the vehicle body, and the flange portion 75 below the pillar constituting portion 86 of the side sill constituting portion 85. On the other hand, the plate portions 72 to 74 and the flange portion 75 extend to the lower side of the pillar constituting portion 87 rearward of the vehicle body, and the flange portion 75 is positioned below the pillar constituting portion 87 of the side sill constituting portion 85. Will be welded. Of course, flange portions may be formed at both ends of the plate portions 72 to 74 in the longitudinal direction of the vehicle body and welded to the side sill component 85.

  According to the second embodiment, the same effect as that of the first embodiment can be obtained, and the bracket 70 extends to the pillar components 86 and 87 on both sides of the side sill outer 60 in the longitudinal direction of the vehicle body. Therefore, it is possible to effectively reinforce the base portions of both pillar components 86 and 87 that are weak in strength without increasing the thickness of the side sill outer 60. Therefore, the side sill outer 60 can be reliably reinforced while suppressing an increase in weight.

  In the second embodiment, it is possible to adopt a structure in which the bracket 70 extends only to one of the pillar components 86 and 87.
