Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for a bumper fascia in which a gap is provided between the upper edge of the bumper fascia and the outer edge of a vehicle body.

(Conventional technology) Conventionally, the mounting structure of bumper surfaces is as follows:
For example, the one described in Japanese Utility Model Application Publication No. 59-156841 is known.

In this conventional structure, a fascia side flange is formed by extending vertically from the vehicle body side end of a bumper fascia that covers the front bumper, and this flange is attached to a mounting flange of the vehicle body with a fixing device. In this case, a shielding piece was integrally molded and protruded toward the engine compartment to prevent the inside of the bumper fascia and the built-in contents of the hood from being directly visible.

(Problems to be Solved by the Present Invention) In the conventional bumper faceia mounting structure as described above, the flange extends directly from the upper edge of the bumper facer in the vertical direction.
If the tightening force of the fixture is too strong, the thickness of the flange on the fascia side is not constant, or the bending angle of the flange on the fascia side varies, etc., when the bumper fascia is fixed, the outer surface side of the bumper fascia may There is a problem in that a difference in tensile force occurs between the inner surface and the outer surface of the upper edge of the bumper face.

Furthermore, because the wall thickness of the upper edge of the bumper face is different between the part where the flange is arranged below and the part without, there is also the problem that sink marks occur on the outer surface of the upper end edge of the bumper face during molding. It was hot.

An object of the present invention is to provide a bumper fascia mounting structure that does not cause distortion or sink marks on the outer surface of the upper edge of the fascia.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, the bumper face is disposed on the vehicle body with its upper end edge being spaced from the outer plate edge of the vehicle body, and In a bumper face mounting structure in which a flange extends downward from the upper end edge and is attached to the vehicle body, there is a space between the upper end edge of the bumper face and the flange, and the outer plate of the vehicle body extends from the upper end edge of the bumper faceia to the flange. A bent portion is provided with an inclined upper surface formed to protrude diagonally downward at a shallow inclined angle toward the vehicle body, and a folded portion that is folded back toward the outside of the vehicle body. A notch is formed in a dogleg shape symmetrically with the folded portion, and the bent portion is arranged such that the inclined upper surface is located below the edge of the outer plate, and the folded portion is formed in the notched portion. The means is placed facing the

(Function) In the mounting structure of the bumper face of the present invention, the flange is not suddenly bent at a steep angle from the upper end edge of the bumper face and extended downward, but the inclined upper surface is inclined at a shallow angle from the upper end edge. A flange is provided via a bent portion having a folded portion. Therefore, the thickness change is small in the portion from the upper end edge of the bumper face to the inclined upper surface.

Therefore, sink marks during molding occur mainly at the folded portion of the folded portion, and no sink marks occur at the upper edge of the bumper face.

In addition, when a folded part is provided at the lower part of the inclined upper surface of the bent part, the wall thickness of this part changes greatly and a sink mark occurs in this part, but this inclined upper surface is Since it is inclined downward toward the outer panel of the vehicle body at a position lower than the edge of the bumper face and the upper edge of the bumper face, sink marks occurring in this area are difficult to notice.

Further, when the bumper face is attached, if the tightening force applied to the flange is uneven between the front side and the back side, the resulting strain is absorbed by the bent portion. That is, the distortion is absorbed by a change in the bending angle at the bending part or by distortion occurring on the inclined surface of the bending part, such as the inclined upper surface.

Therefore, no distortion occurs at the upper edge of the bumper face.

In addition, since the bent portion protrudes toward the outer side of the vehicle body, when the bumper face is installed,
The inner part can be hidden from direct view from outside the vehicle through the gap between the upper end of the fascia and the outer panel of the vehicle body. In both cases, the folded portion of the dogleg-shaped bent portion and the cutout portion are opposed to each other to close the gap, so variations in the gap become less noticeable and gap adjustment work can be omitted.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

2 is a perspective view showing the front part of a vehicle body to which the bumper facia mounting structure of this embodiment is applied, and in the drawing, the bumper facia is designated by 1. This bumper facia 1 is provided to cover a front bumper (not shown), and is made of an elastically deformable resin such as urethane or polypropylene.

Further, on the vehicle body 2 behind the bumper face 1, there are head lamp covers 3, 4 on both left and right sides.
A finisher 5 (corresponding to a vehicle body outer plate in the claims) is provided in the center to cover an inspection hole (not shown), and an engine hood 21 is provided behind the finisher 5.

Incidentally, as shown in FIG. 1, a bracket 22 is provided below the finisher 5.

FIG. 1 is a sectional view (second
AA cross section), a bent part 6 and a flange 7 are provided continuously on the upper edge 11 of the bumper face 1, and the bumper face 1
is the upper edge 11 and the front edge 5 of the finisher 5.
1 with a gap d between them.

The bent portion 6 is formed in a shape that is bent obliquely downward from an upper end bending point 61 of the upper end edge of the bumper face 1 toward the center of the vehicle body, and forms an inclined upper surface 62.
is formed, and is further folded back toward the front of the vehicle body from a folded portion 63 provided at the lower end of the inclined upper surface 62 to form a substantially dogleg shape.

Further, the inclined upper surface 62 is arranged at a lower position than the front end edge 51 of the finisher 5. A notch 52 is formed in the front edge 51 of the finisher 5 in a substantially dogleg shape symmetrically with the bent part 6, and there is a certain gap between the bent part 6 and the bent part 6. A gap is formed.

Furthermore, the bumper face 1 is bent in the vertical direction at a lower end bending point 64 formed below the upper end edge 11, and the flange 7 extends from this lower end bending point 64. This flange 7 is for attachment to the vehicle body 2,
A mounting hole 71 is drilled.

The bent portion 6 and the flange 7 are formed to have substantially the same thickness as the other portions of the bumper face 1.

As shown in FIG. 1, the flange 7 is attached to the support 8 using bolts 72, nuts 73, and a retainer 74 so that the flange 7 is held between the support 8 and the retainer 74. The support 8 is attached to a bracket (not shown) to which the headlamp covers 3 and 4 of the vehicle body 2 are attached.

Next, the operation of the embodiment will be explained.

In the mounting structure of the bumper face according to the embodiment of the present invention, the bending angle at the upper end bending point 61 is a shallow angle, and the wall thickness changes in the portion from the upper end edge 11 of the bumper face 1 to the inclined upper surface 62. is getting smaller. Therefore, during molding, no sink marks occur on the upper edge, improving the appearance.

On the other hand, the bent portion 6 is bent at a steep angle at the folded portion 63, and the thickness change is large at this portion. Therefore, sink marks occur on the inclined upper surface 62 of the bent portion 6 during molding. However, the sloping upper surface 62 is formed on the front edge 51 of the finisher 5 and the upper edge 1 of the bumper face 1.
Since it is located at a lower position than 1 and is slanted toward the center of the vehicle body, sink marks that occur in this area are less noticeable to the public and do not make it look unsightly.

Further, when the bumper face 1 is attached, if the tightening force to the flange 7 is uneven between the front side and the back side, the resulting strain is absorbed by the bent portion 6. That is, the distortion is absorbed by changing the bending angle at the folded part 63 of the folded part 6 or by causing distortion in the inclined upper surface 62.

Therefore, the upper end edge 11 of the bumper face 1 is not distorted, and the appearance is improved.

Furthermore, since the bent portion 6 protrudes toward the finisher 5 side, when the bumper facer 1 is installed, the inner part cannot be seen from the outside of the vehicle through the gap between the upper edge 11 of the bumper facer 1 and the finisher 5. It can be hidden like this.

Although the embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment. Although an example is shown in which the bent portion is formed into a dogleg shape, the bent portion is not limited to this shape, and the bent portion may have a shape with a bent point at a shallower angle between the inclined upper surface and the folded portion. .

Further, in the embodiment, the bumper face of a front bumper is shown as an example, but the present invention can also be applied to a rear bumper.

(Effects of the Invention) As described above, the mounting structure of the bumper face of the present invention has the effect that sink marks and distortions do not occur at the upper end edge of the bumper face. In addition, the bent portion to prevent sink marks or distortion from occurring at the upper end edge of the bumper face can also be used as a shielding plate to prevent the inside from being seen through the gap with the outer panel of the vehicle body. The effect is that the structure can be simplified.
