DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure of a vehicle exterior component for mounting a vehicle exterior component (for example, an airflow control member such as an aero member) to a member to be mounted on a vehicle body.

[0002]

2. Description of the Related Art In order to attach a resin aero member (air spoiler body) to a lower portion of a resin bumper cover member of a vehicle, Japanese Utility Model Laid-Open Publication No. 2-136787 and Japanese Patent Publication No. 5-2 have been disclosed.
Bolts are used as described in 1779. In these conventional examples, the upper edge portion of the aero member is brought into contact with the lower portion of the bumper cover member, and both are fixed by bolts at a plurality of positions in the width direction of the vehicle body.

[0003]

An aero member such as an air spoiler is a long resin part extending in the width direction of a vehicle body. Therefore, the upper edge portion of the aero member is liable to cause so-called wavy deformation due to molding errors or expansion or contraction due to temperature changes. For this reason, a gap may be formed between the upper edge portion of the aero member and the bumper cover member, and the appearance may be deteriorated. Further, since the bolts for fixing the aero member and the bumper cover member are located at a position away from the upper edge of the aero member, and the rigidity of the upper edge of the aero member is low, the upper edge of the aero member is vibrated during traveling. There was a risk of flapping.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a structure for fixing a vehicle exterior component such that the vehicle exterior component such as an aero member can be attached to a mounting member on the vehicle body side such as a bumper cover member with good appearance. It is in.

[0005]

According to the present invention, there is provided a structure for fixing a vehicle body exterior component, wherein a screw member for fixing the vehicle body exterior component and a mounting partner member to each other is tightened. With the decrease in the distance between the opposing wall of the body exterior component and the mounting wall of the mounting partner member, the inclined surface of the projection provided on the opposing wall has a positioning hole formed in the mounting wall. While being in contact with the opening edge, the upper edge portion of the vehicle body exterior article is urged toward the mating surface of the attachment partner member. For this reason, by tightening the screw member, the exterior body of the vehicle body and the attachment partner are fixed, and the upper edge of the exterior body of the vehicle comes into contact with the mating surface of the attachment partner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a part of a front bumper cover member 10 made of synthetic resin and a part of an aero member 11, which are mounted on the vehicle body side of a vehicle (in this case, an automobile). The aero member 11 is an example of a vehicle exterior component according to the present invention, and the bumper cover member 10 is an example of an attachment partner. The dashed line C in FIG. 1 indicates the center in the width direction of the vehicle body. An air inlet 12 is formed at the center of the bumper cover member 10.

[0007] The aero member 11 is a bumper cover member 10.
Are fixed to the lower part of the bumper cover member 10 by the screw members 16 at the mounting portions 15 provided at a plurality of locations in the longitudinal direction. The screw member 16 referred to in this specification is constituted by a bolt 17 and a nut 18. The mounting portions 15 have substantially the same structure except for a mounting portion 15 ′ for fixing the end 11 a of the aero member 11. Therefore, the mounting portions 15 shown in FIGS. Will be described.

[0008] As shown in FIG.
A mating surface 21 extending inwardly of the vehicle body at a lower edge portion 20 thereof; a mounting wall 22 extending downward from an end of the mating surface 21 on the vehicle inner side; A flange portion 23 extending toward one side is integrally provided.
The mating surface 21, the mounting wall 22, and the flange portion 23 are integrally formed along the longitudinal direction of the bumper cover member 10 over substantially the entire length of the bumper cover member 10, respectively.

A positioning hole 25 is formed in the upper part of the mounting wall 22. Screw insertion hole 2 below positioning hole 25
6 are formed. Positioning hole 25 and screw insertion hole 26
Respectively penetrate the mounting wall 22 in the thickness direction (almost horizontal direction). In FIG. 1, the screw insertion hole 26 of the mounting portion 15 located on the center C of the vehicle body is
It is a circular hole because it serves as a reference for positioning the aero member 11 in the longitudinal direction with respect to. As shown in FIG. 3, the screw insertion hole 26 of the other mounting portion 15 is
It is a long hole along the longitudinal direction so as to absorb the positional displacement between the aero member 11 and the longitudinal direction.

On the other hand, the aero member 11 includes an extended portion 31 extending substantially horizontally from the upper edge portion 11b of the aero member main body 30 along the mating surface 21, and a vehicle inward side of the extended portion 31. Opposing wall 32 extending substantially downward along the mounting wall 22 from an end of the aero member main body 3
The aero member main body 30 has a leg portion 33 that connects the back surface thereof, a rib 34 formed on the back surface of the aero member main body 30, and the like. By integrally molding the aero member main body 30, the extending portion 31, the opposing wall 32, and the leg 33, a bag-shaped closed cross section 35 is formed on the upper edge 11 b of the aero member 11.

At the upper part of the opposing wall 32, a convex part 40 protruding toward the mounting wall 22 is formed. A mounting hole 41 for inserting the bolt 17 is formed below the protrusion 40.
The bolt 17 includes a shaft portion 45 having a thread and a shaft portion 4.
The shaft 45 is inserted into the mounting hole 41.

As shown in FIG. 4, a slit 50 communicating with the mounting hole 41 is opened on the side surface 51 of the opposing wall 32. Therefore, the shaft portion 45 of the bolt 17 can be inserted into the mounting hole 41 from the side surface 51 of the opposing wall 32 via the slit 50. The width W of the slit 50 is slightly smaller than the outer diameter of the shaft 45.

The head 46 of the bolt 17 is inserted into a bag-shaped closed section 35 surrounded by the extension 31, the opposing wall 32, and the leg 33. Flat portions 56 for preventing rotation are formed on both side surfaces of the head 46 of the bolt 17. Closed section 3
The end face 57 of the head 46 inserted into the end 5 opposes the tip of the rib 34, thereby restricting the position of the bolt 17 in the axial direction.

The convex portion 40 has an inclined surface 61 on the lower surface side so as to be tapered from the base to the tip 60. When the nut 18 is fastened to the bolt 17, the inclined surface 61 comes into contact with the opening edge 25 a of the positioning hole 25 as the distance S between the opposing wall 32 and the mounting wall 22 decreases as shown in FIG. 5. While the upper edge 11b of the aero member 11
Are inclined toward the mating surface 21. Note that a seal member 62 may be provided between the lower edge 20 of the bumper cover member 10 and the upper edge 11b of the aero member 11.

Next, a procedure for fixing the aero member 11 to the bumper cover member 10 will be described. First, the bolt 17 is attached to the facing wall 32 of the closed section 35 of the aero member 11. That is, as shown in FIG. 4, the shaft portion 45 of the bolt 17 is inserted into the mounting hole 41 from the side surface 51 of the facing wall 32 through the slit 50, and
6 is accommodated in the gap between the tip of the rib 34 and the opposing wall 32. Since the width W of the slit 50 is slightly smaller than the outer diameter of the shaft portion 45 of the bolt 17, the shaft portion 4 inserted into the mounting hole 41
5 can be prevented from falling out of the slit 50.

After the bolt 17 is attached to the aero member 11, the tip of the bolt 17 is inserted into the screw insertion hole 26 of the bumper cover member 10, and the nut 18 is provided with the washer 65 provided between the bolt 17 and the mounting wall 22. To the shaft 45. Then, the nut 18 is tightened to the bolt 17 by rotating the nut 18 with a tool. When the nut 18 is rotated, the distance S (shown in FIG. 5) between the facing wall 32 of the aero member 11 and the mounting wall 22 of the bumper cover member 10 gradually decreases.

When the screw member 16 is tightened, there is initially a gap G between the upper edge 11b of the aero member 11 and the lower edge 20 of the bumper cover member 10, as shown in FIG. Also, as the nut 18 is tightened, the inclined surface 61 of the convex portion 40 comes into contact with the lower opening edge 25a of the positioning hole 25 of the bumper cover member 10, and as the distance S gradually decreases, the aero member 11 The upper edge 11b is pushed up toward the mating surface 21 of the bumper cover member 10.

Therefore, when the tightening of the screw member 16 is completed, the aero member 11 is fixed to the bumper cover member 10 and at the same time, the upper edge portion 11b of the aero member 11 is connected to the lower edge portion 20 of the bumper cover member 10. It is in a state of close contact. Since the mounting portions 15 are provided at a plurality of positions in the longitudinal direction of the aero member 11 at a predetermined pitch, the aero member 11
The aero member 11 can be attached to the bumper cover member 10 with good appearance without causing a wavy deformation or a gap between the bumper cover member 10 and the aero member 11 over the entire length of the bumper cover member 10.

Further, since the closed section 35 is formed along the upper edge 11b of the aero member 11, the rigidity of the upper edge 11b is increased as compared with the case where the closed section 35 is not provided. be able to. The aero member 1 is fixed by the bolt 17 provided on the opposed wall 32 of the closed section 35 having high rigidity.
The upper edge portion 11 b is fixed to the bumper cover member 10.

For these reasons, the upper edge portion 11b of the aero member 11 can be fixed to the lower edge portion 20 of the bumper cover member 10 with sufficient strength without forming a gap. The problem that the upper edge 11b flutters can also be avoided.

The above-described fixing structure of the present invention can be applied to a case in which a vehicle exterior component other than the aero member is fixed to a mounting partner on the vehicle body side. Further, in carrying out the present invention, the components of the present invention, such as the mating surface of the mating member and the mounting wall, the extending portion of the body exterior component, the facing wall or the shape of the convex portion, are not departed from the gist of the present invention. It goes without saying that various changes can be made.

[0022]

According to the first aspect of the present invention, a vehicle exterior component such as an aero member can be fixed to a mounting counterpart member such as a bumper cover member in a good appearance, and the appearance is improved.
In addition, the rigidity near the upper edge of the body exterior component can be increased by the extended portion and the opposing wall formed on the body exterior component,
Since the exterior body of the vehicle body is fixed to the mating member by the screw member provided at this portion, it is possible to prevent the upper edge of the exterior vehicle body from fluttering due to vibration during traveling.
