BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior component such as a side stone guard, a spoiler, and a bumper that is attached to a vehicle body by using a clip.

[0002]

2. Description of the Related Art In vehicles such as automobiles,
Exterior parts such as a side stone guard, a spoiler, and a bumper are attached to a vehicle body by using clips (Japanese Patent Laid-Open No. 8-175288). This exterior component generally has a base plate and a substantially box-shaped box portion projecting from the inner surface of the base plate, and is integrally injection-molded with a resin material. When the vehicle is assembled, the outer surface of the base plate is exposed to the outside of the vehicle and functions as a decorative portion. The box part has three wall parts standing upright from the base plate, that is, a pair of side wall parts and a connecting wall part that connects one ends of the both side wall parts, and a clip is inserted between the other ends of the both side wall parts. An opening is formed.

[0003]

As a problem of such exterior parts, firstly, it is required to improve the appearance quality in a vehicle assembled state. However, if all three wall portions of the box portion are integrally connected to the base plate, sink marks, wrinkles, and the like may occur on the outer surface of the base plate located on the back side of these wall portions, which may impair aesthetics.
In particular, when the side wall portion is set parallel to the character line provided on the outer surface of the base plate, the sink mark formed on the back surface side of the connecting wall portion greatly impairs the aesthetic sense.

In the above-mentioned Japanese Patent Laid-Open No. 8-175288, a portion (hollow portion 2) in which a box portion (fitting portion 36) is formed in the base plate (decorative portion 20).
2) is formed in a hollow shape. In this case, since the sink marks and wrinkles formed on the back side of the box portion do not appear outside the vehicle, the appearance quality is excellent. However, the base plate must be molded into a hollow shape by the hollow injection molding method, which is difficult to manufacture, the manufacturing cost is high, and the shape is inevitably complicated and large.

Secondly, the box portion is required to have such a rigidity that the clip can be held well. That is, if the rigidity of the box portion is low, when the clip is pushed into the vehicle body by pressing the outer surface of the base plate, the box portion bends and the clip falls down, and this clip can be inserted well into the body. It may run out.

The present invention has been made in view of these problems, and an object of the present invention is to provide a new vehicle exterior component which can improve both the appearance quality and the rigidity of the box portion. There is.

SUMMARY OF THE INVENTION The present invention is an exterior component that is attached to a vehicle body using a clip,
It has a base plate and a substantially box-shaped box portion protrudingly formed from the side surface of the base plate. The exterior component is a side stone guard, a decorative molding, or the like, and is generally made of a resin material and integrally molded by injection molding. Further, typically, in a state where the exterior component is assembled to the vehicle, the outer surface of the base plate is exposed to the outside of the vehicle and functions as a decorative portion. A box portion is formed so as to project on the inner surface of the base plate.

The box portion has a pair of side wall portions that stand upright from the base plate and face each other, and a connecting wall portion that connects one ends of both side wall portions to each other, and the other end portion of the pair of side wall portions. An opening for inserting the clip is formed therebetween. Further, typically, the box portion is provided with a ceiling piece portion that is integrally connected to the edge portions of the side wall portion and the connecting wall portion and faces the base plate, and the clip is slidably held on the ceiling piece portion. It

According to the present invention, a hole is formed between the connecting wall portion and the base plate, and a peripheral portion of the hole in the connecting wall portion is formed in a direction opposite to the opening portion substantially parallel to the base plate. It is characterized in that a main rib protruding inward is formed.

Due to the hole, the connecting wall and the base plate are substantially in non-contact with each other. Therefore, it is possible to effectively suppress sink marks, wrinkles, and the like that occur on the side surface of the base plate located on the back side of the box portion (the outer surface that is exposed to the outside of the vehicle when the vehicle is assembled), and improve the appearance quality. In particular, if both side wall parts are set parallel to the character line provided on the outer surface of the base plate, even if the outer surface of the base plate located on the back side of the side wall part has a sink mark, this sink mark follows the character line, It does not spoil the beauty.

Although there is a concern that the rigidity (strength) of the connecting wall portion will decrease due to the above-mentioned hole, since the main rib is provided at the peripheral portion of the hole in the present invention, the rigidity of the box portion including the connecting wall portion is reduced. Secured enough. Therefore, the clip can be satisfactorily pushed into the vehicle body without concern about the clip falling over. Further, since the main rib is formed to project in the direction opposite to the opening, there is no fear that the clip will interfere with the main rib when the clip is inserted from the opening of the box portion.

Preferably, the hole has a sufficiently small height from the base plate and the height is set to be substantially constant so as not to excessively reduce the rigidity of the box. . Further, in order to suppress sink marks, wrinkles, etc., the hole portion is formed to be sufficiently extended so as to extend over both side wall portions. That is, the connecting wall portion is almost completely brought into non-contact with the base plate.

In order to further improve the rigidity of the box portion including the connecting wall portion, it is preferable that one surface is connected to the side surface of the main rib and the other surface is connected to the side surface of the connecting wall portion. Are integrally formed.

More preferably, in the both side wall portions,
The base portion connected to the base plate is partially thinned. In this case, the area where the side wall portion is connected to the base plate is reduced, and sink marks, wrinkles, and the like that occur on the back surface side of this connection portion are suppressed, so that the appearance quality can be further improved.

[0015]

As described above, according to the present invention, it is possible to improve the appearance quality and secure the rigidity of the box portion at a high level in the exterior parts of the vehicle.

1 to 7 show a first embodiment of a vehicle exterior component 10 according to the present invention. Note that FIG.
2 is a sectional view taken along the line BB of FIG. 2, FIG. 4 is a sectional view taken along the line CC of FIG. 2, and FIG. 7 is a sectional view taken along the line AA of FIG.

As shown in FIG. 7, the exterior component 10 is attached to the body 1 on the side of the vehicle by using a clip 11, and is also called a side stone guard or a decorative molding. The exterior component 10 includes a thin plate-shaped base plate 12 that is appropriately curved, a substantially box-shaped box portion 14 integrally formed on the inner side surface 12 b of the base plate 12, and a clip holding portion 15. The resin material is injection-molded integrally with each part. The exterior component 10 is mounted on a vehicle, and the outer surface 1 of the base plate 12 is
2a is exposed to the outside of the vehicle, functions as a vehicle decoration, and has a function of protecting the body 1 from stones and the like. The base plate 12 is formed with a concave portion 13 which is recessed in an arc shape so as to bypass the tire of the vehicle.
A plurality of box portions 14 and clip holding portions 15 are intermittently provided, and the clips 11 are respectively received and temporarily held by the box portions 14 and clip holding portions 15.

Referring to FIGS. 1 to 4, the clip 11 is integrally formed by a small diameter neck portion 17 and an insertion portion 16 having a substantially S-shaped cross section which is inserted into the vehicle body 1 and fitted therein. The first and second flange portions 18 and 19 which are connected to each other and are opposed to each other at an interval corresponding to the length of the neck portion 17,
For example, each part is integrally formed of a resin material.

The box portion 14 has a pair of side wall portions 20 standing upright from the base plate 12 and facing each other, and a connecting wall portion 21 connecting one ends of the both side wall portions 20 to each other.
A ceiling piece 22 that is integrally connected to the upper edges of the two walls 20 and 21 and that faces the base plate 12 substantially in parallel;
have. An opening 23 into which the clip 11 is inserted is formed between the other ends of the side wall portions 20. Therefore, the box portion 14 has a substantially box shape with one side opened as a whole.

A slide groove 24 extending in parallel with the side wall portion 20 is formed in the ceiling piece portion 22, and one end of the slide groove 24 is open to the opening portion 23 side. By fitting the neck portion 17 of the clip 11 into the slide groove 24 and sliding the clip 11, as shown in FIGS. 2 and 3, the ceiling piece portion 22 is provided between the flange portions 18 and 19 of the clip 11. The clip 11 is tentatively held by the box portion 14 in the sandwiched state. In this temporary holding state, the positioning protrusion 25 formed on the ceiling piece 22 is engaged with the tapered surface of the clip 11, and the clip 11 is positioned in the sliding direction with respect to the box portion 14.

Between the connecting wall portion 21 and the base plate 12, a hole portion 26 having a groove shape whose height ΔH from the base plate 12 is substantially constant is formed. In other words, in the connecting wall portion 21, the base portion connected to the base plate 12 is cut out in a strip shape, and this cut portion corresponds to the hole portion 26. The hole portion 26 is formed to extend over substantially the entire length of the connecting wall portion 21 so as to straddle both side wall portions 20. However, a part of the side wall portions 20a is slightly left at both ends of the hole portion 26.

A main rib 27 is integrally formed on the peripheral edge of the hole 26 in the connecting wall portion 21 so as to project substantially parallel to the base plate 12 in the direction opposite to the opening 23 (to the right in FIG. 3). The main ribs 27 appropriately strengthen the rigidity of the connecting wall portion 21, and thus the box portion 14. The main rib 27 has a substantially rectangular cross section, and one end of the main rib 27 faces the hole 26 and the end face 2 of the connecting wall 21.
1a (Fig. 3) is smoothly continuous. In other words,
The main rib 27 is bent and formed at a substantially right angle from the end portion of the connecting wall portion 21 on the hole 26 side.

As shown in FIGS. 1 and 2, the main rib 2
The holes 26 are provided at both ends of the hole 7 mainly for the purpose of improving rigidity.
A bent portion 28 that bends toward the base plate 12 side is slightly formed along the peripheral edge portion of the. However, in order to suppress the occurrence of sink marks and wrinkles, the bent portion 28 does not extend to the base plate 12, and a slight gap 29 is formed between the bent portion 28 and the inner surface 12b of the base plate 12. Has been secured.

Referring to FIG. 4, in order to suppress the occurrence of sink marks and wrinkles, the base portion 31 integrally connected to the base plate 12 in the side wall portion 20 is partially thinned. ing. That is, the thickness D2 of the base portion is set shorter than the thickness D3 of the other general side wall portions 20.

As described above, in this embodiment, the connecting wall portion 21
A hole 26 is extended between the base plate 12 and the base plate 12, and substantially all of the connecting wall portion 21 is formed by the base plate 1.
Since it is not in contact with 2, the sink marks, wrinkles and the like that occur on the outer surface 12a of the base plate 12 located on the back surface side of the side wall portion 20 are suppressed, and the appearance quality is improved.

Further, as shown in FIG. 6, the outer surface 12a of the base plate 12 is generally provided with a decorative character line L extending in the vehicle front-rear direction.
The side wall portion 20 is arranged parallel to the character line L. Therefore, even if a sink mark along the side wall portion 20 occurs on the outer surface 12a of the base plate 12, it is not very noticeable, and there is not much problem in appearance quality. Conversely, if a sink mark occurs in the direction orthogonal to the character line L, it is very noticeable and the appearance quality is significantly impaired. However, in the present embodiment, the connection extending in the direction orthogonal to the character line L is conspicuous. Since the wall portion 21 is in a non-contact state with the base plate 12, there is no possibility of causing such sink marks.

Since the holes 26 are formed in this way,
Although there is concern that the rigidity of the box portion 14 including the connecting wall portion 21 may be reduced, in the present embodiment, since the main rib 27 is formed to project at the peripheral edge portion of the hole portion 26, the box including the connecting wall portion 21 is formed. The rigidity of the portion 14 is effectively strengthened.
Therefore, when the clip 11 temporarily held in the box portion 14 is pushed into the vehicle body 1 side, the connecting wall portion 21 and the ceiling piece portion 22 do not excessively bend and the clip 11 does not fall down. It can be pushed into the body 1 side satisfactorily.

Since the main rib 27 has a simple rectangular cross section and is bent from the end of the connecting wall 21, it does not complicate the injection molding of the exterior component 10 itself. . That is, the exterior component 10 of the present embodiment is easier to manufacture and advantageous in cost as compared with the one requiring hollow injection molding as in the above-mentioned Japanese Patent Laid-Open No. 8-175288. Furthermore, since the main rib 27 projects in the direction opposite to the opening 23,
There is no risk of interfering with the clip 11 attached to the box portion 14.

8 and 9 show a second embodiment of the present invention. Here, the same components as those in the first embodiment are designated by the same reference numerals, and the overlapping description will be omitted. Only the portions different from the first embodiment will be described.

In the second embodiment, the box portion 14 is integrally formed with the sub-lip 32. One surface of the sub-lip 32 is integrally connected to a side surface of the main rib 27 on the side opposite to the base plate 12, and the other surface of the sub-lip 32 is integrally connected to a side surface on the side opposite to the opening 23 of the connecting wall portion 21. . That is, the sub lip 32 is
It has a substantially triangular cross-section that spans the side surface of the main rib 27 and the side surface of the connecting wall portion 21. A plurality (here, two) of such sub-lips 32 are intermittently provided. By providing such a sub-lip 32, the rigidity of the box portion 14 including the connecting wall portion 21 can be more effectively improved with a simple structure.
