Description
Technical Field
The utility model relates to a car body lateral part structure.
Background
In the related art, as a vehicle body side portion structure, a structure in which a lower end of a center pillar is joined to a side sill has been widely adopted. Fig. 3 is a perspective view showing a joint portion between the center pillar 1 and the side sill 2. Fig. 4 is a sectional view taken along line IV-IV in fig. 3. IN each figure, the direction of arrow IN indicates the inside IN the vehicle width direction; the direction of arrow FR indicates the front side in the vehicle body front-rear direction; the direction of arrow UP indicates the upper side.
The side sill 2 is joined by a side sill inner panel 21 and a side sill reinforcing panel 22 each having a hat-shaped cross section to constitute a closed cross-sectional structure. The vertical portion 23 of the rocker inner panel 21 is joined to one end (the outer end in the vehicle width direction) of the floor panel 3. A carpet 4 is laid along the floor 3 and the vertical portion 23 of the side sill inner panel 21. Further, a side sill outer panel 24 as a decorative panel is disposed on the vehicle width direction outer side of the side sill reinforcing panel 22. Symbol 7 in fig. 4 denotes a side door.
The center pillar 1 is joined to a center pillar outer panel 11 and a center pillar inner panel 12 each having a hat-shaped cross section to form a closed cross-sectional structure. The lower end of the center pillar outer panel 11 is joined to the vertical portion 25 of the side sill reinforcing panel 22. A center pillar lower gusset 13 is joined to a lower end portion of the center pillar inner panel 12. The center pillar lower gusset 13 overlaps the upper plate portion 26 and the vertical portion 23 of the rocker inner panel 21, respectively. The center pillar lower gusset 13 includes a horizontal portion 14 extending along the upper plate portion 26 of the rocker inner panel 21 and a vertical portion 15 extending along the vertical portion 23 of the rocker inner panel 21, and the horizontal portion 14 is overlapped and joined (spot welded) to the upper plate portion 26 of the rocker inner panel 21 and the vertical portion 15 are joined to the vertical portion 23 of the rocker inner panel 21, respectively.
The upper plate portion 26 of the rocker inner panel 21 and the horizontal portion 14 of the center pillar lower gusset 13 are formed with a wire clip mounting hole H, respectively. The clip mounting hole H is a hole provided for mounting the clip member 5, and the clip member 5 is used to fix the wire harness WH arranged along the side member 2 and extending in the vehicle body front-rear direction.
In the above-described vehicle body side portion structure, when the vehicle passes a road surface or the like where water accumulates, the water may enter the inside of the side member 2. For example, water may enter the rocker 2 through a hole provided in the rocker 2 for paint removal in an electric spray painting (electric spray painting in a vehicle body production line), a small gap existing in a portion where the rocker inner panel 21 overlaps the rocker reinforcement panel 22, or the like. In this case, if the water surface of the water entering the rocker 2 is wavy as the vehicle travels, the water may flow into the vehicle interior through the clip mounting hole H from a gap (a gap generated in a region other than the spot welding point) between the upper plate portion 26 of the rocker inner panel 21 and the horizontal portion 14 of the center pillar lower gusset 13 (as indicated by a broken-line arrow in fig. 4).
As a means for solving the above problem, it is conceivable to adopt the structure shown in fig. 5. That is, before the center pillar lower gusset 13 is overlapped with the rocker inner panel 21, the seal member 6 surrounding the clip attachment hole H is adhered to the upper surface of the upper plate portion 26 of the rocker inner panel 21. The sealing member 6 is made of resin or rubber. That is, the seal member 6 surrounding the clip mounting hole H is disposed between the side sill inner panel 21 and the center pillar lower gusset 13, and the waterproof function of the seal member 6 prevents water from flowing into the vehicle interior (as indicated by the broken line arrow in fig. 5) from the gap between the side sill inner panel 21 and the center pillar lower gusset 13. In the above configuration, an adhesive may be applied instead of the sealing member 6.
However, in the case of the above-described configuration, since the center pillar lower gusset 13 is overlapped on the upper plate portion 26 of the side sill inner panel 21 after the sealing member 6 is bonded, when the side sill inner panel 21 is moved in the horizontal direction with respect to the center pillar lower gusset 13 as shown in fig. 6 when the operation of overlapping the two is performed, the center pillar lower gusset 13 comes into contact with the sealing member 6, and an external force in a direction (see a dotted arrow in fig. 6) to peel off the sealing member 6 may be applied. If the sealing member 6 is peeled off, the waterproof function as described above cannot be exerted.
