Description

  The present invention relates to a structure of a garnish mounting portion of a vehicle such as an automobile.

As an example of the structure of the garnish attachment portion of a vehicle, there is one described in Patent Document 1.
In the structure described in this document, a garnish that constitutes a rear spoiler is attached to an outer panel that constitutes a roof portion or the like of a vehicle. A gap is formed between the edge of the garnish and the outer panel, and a rubber lip member is attached to the garnish to close the end opening of the gap. The lip member includes a first portion that closes the end opening of the gap, and a second portion that extends from the first portion toward the back side of the gap.
According to such a configuration, the first portion of the lip member can prevent a so-called intermediate state in which the end opening of the gap looks unnatural from the outside of the vehicle. Further, the second portion of the lip member can prevent the garnish from being deformed and colliding directly with the outer panel when a force is applied to the garnish, so that a loud collision sound is not generated. is there.

  However, the prior art still has room for improvement as described below.

In other words, the thickness of the second portion of the lip member is considerably smaller than the width of the gap between the outer panel and the garnish. For this reason, when the edge part of a garnish receives a pressing force and deform | transforms into the outer panel side, the 2nd part does not exhibit the effect | action which suppresses such a deformation | transformation appropriately in the initial stage of this deformation | transformation start. As a result, the vicinity of the edge portion of the garnish is considerably depressed, resulting in a state where there is no rigidity or a lack of rigidity.
In designing and manufacturing the lip member, as with other parts of the car body, it is easy to manufacture and reduces the manufacturing cost and reduces the overall weight. It is desired to be able to plan. Therefore, it is necessary to consider such a case when solving the above-described problems.

Japanese Patent Laid-Open No. 2006-137764

  The present invention has been conceived under the circumstances as described above, and is a vehicle garnish capable of appropriately increasing the rigidity of the garnish while appropriately reducing the weight and reducing the manufacturing cost. The problem is to provide the structure of the mounting portion.

  In order to solve the above problems, the present invention takes the following technical means.

The structure of the garnish attachment portion of the vehicle provided by the present invention is disposed in a gap between the garnish and the garnish that are attached to the panel so as to cover the panel as a vehicle body constituting member. A lip member, and the lip member includes a first portion for closing an end opening inside an end edge of the garnish, and the gap from the first portion. And a second part connected to the first part so as to extend to the back side of the vehicle, wherein the lip member is a part of the second part. A third portion connected to the rear portion and having a thickness in the width direction of the gap larger than that of the second portion is further included.

According to such a configuration, the following effects can be obtained.
That is, since the lip member has the third portion as a thick portion located in the gap between the garnish and the panel, the edge portion of the garnish is appropriately adjusted by the third portion of the lip member. The third portion can appropriately prevent the end edge portion from being greatly deformed when the end edge portion of the garnish is pressed. Therefore, it is possible to sufficiently and effectively increase the rigidity of the garnish. In the present invention, when the garnish and the panel are clipped, for example, the distance from the position of the clip stop to the edge of the garnish is long, and the edge of the garnish is inherently easily deformed. In some cases, it will be more suitable.
Furthermore, in addition to the third portion of the lip member, the second portion can be used as a portion for attaching the lip member to the garnish or the panel. For example, it is possible to attach the lip member to the garnish or the panel firmly and stably by making one side of each of the second and third parts a joint surface having a relatively large area with respect to the garnish or the panel. Is possible.
On the other hand, since the second portion of the second and third portions is a portion having a small thickness, the entire volume of the lip member can be prevented from becoming too large. This is preferable for reducing the manufacturing raw material of the lip member, reducing the manufacturing cost, and reducing the weight.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

It is a side view showing an example of a vehicle to which the structure of the garnish attachment part of the vehicle concerning the present invention is applied. (a) is the IIa-IIa sectional view of FIG. 1, (b) is the IIb-IIb sectional view of FIG. (A) is a side view of the garnish used for the structure of the garnish attachment part of the vehicle shown in FIG. 2, (b) is an exploded side view of (a). (A) is a partially broken perspective view of the lip member used for the structure of the garnish attaching part shown in FIG. 2, (b) is a partially broken perspective view from the opposite direction to (a). is there. It is a partially broken perspective view which shows the other example of this invention.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

1 and 2, the structure A of the garnish attachment portion of the vehicle in the present embodiment is applied to the position of the C pillar 1 of the vehicle V shown in FIG.
As shown in FIG. 2, the structure A of the garnish attaching portion includes a metal side outer panel 10 constituting the C pillar 1, a resin garnish 2 attached so as to cover the outer surface of the side outer panel 10, and a lip member 3 is provided.

Although the side outer panel 10 is omitted in the drawing, a pair of left and right sides are provided in the vehicle width direction, and a region between the pair of side outer panels 10 is a rear opening 4 of the vehicle V, and this rear opening The part 4 is opened and closed by a back door 5 (reference numerals 5a and 5b respectively indicate a back door outer and an inner).

  The garnish 2 covers the outer surface of the side outer panel 10 so that it cannot be seen from the outside of the vehicle, and enhances the design of the C pillar 1. The garnish 2 is basically substantially flat and is clipped to the side outer panel 10. In the same manner as the conventionally known means, this clip fastening is performed by inserting the clip 6 into the holes 21 of the plurality of clip attaching portions 20 protruding from the inner surface of the garnish 2 and the holes 11 formed in the side outer panel 10. Are inserted in series, and the clip 6 is locked to the side outer panel 10 in a retaining state.

  The lip member 3 is an elastic body such as TPO (olefin-based elastomer), and is disposed in the gap 7 between the garnish 2 and the side outer panel 10. The lip member 3 is disposed in the gap 7 by, for example, using a double-sided adhesive tape 8 and bonding one surface of the lip member 3 to the inner surface of the garnish 2. However, as a matter of course, the means for attaching the lip member 3 is not limited to means using the double-sided adhesive tape 8.

  The lip member 3 has a configuration in which first to third portions 31 to 33 described below are integrally formed.

  The first portion 31 is a portion for closing the end opening 7a that is open inside the end edge 2a of the garnish 2 in the gap 7, and is slightly smaller than the width of the end opening 7a. Narrow width (thickness). This eliminates the problem that the attachment of the lip member 3 becomes difficult or unnaturally bent when an assembly error of the garnish 2 occurs and the width of the end opening 7a becomes smaller than a predetermined dimension. To help. Since the end opening 7a of the gap 7 extends in a series in the vertical height direction of the vehicle V, the first portion 31 also extends in the vertical height direction corresponding to this.

  The second portion 32 has a form that intersects and is connected to the first portion 31 and extends from the first portion 31 to the back side of the gap 7. The thickness t2 of the second portion 32 is smaller than the width W1 of the first portion 31.

  The third portion 33 is a portion that is connected to the rear portion of the second portion 32 and has a thickness t3 that is larger than the thickness t2 of the second portion 32. The thickness t3 is equal to or less than the width Wb of the gap 7 (strictly speaking, the width Wb is the width of the gap 7 where the third portion 33 is located). Preferably, the thickness t3 is slightly smaller than the width Wb, and when the width Wb of the gap 7 is smaller than a predetermined dimension due to an assembly error of the garnish 2, the third portion 33 strongly abuts against the side outer panel 10, and a part of the garnish 2 is strongly pressed outward by the third portion 33 by the reaction force so as not to swell.

As shown in FIG. 3 and FIG. 4, the third portion 33 is provided at a plurality of locations at an appropriate interval in the longitudinal direction (vertical height direction) of the lip member 3. A region between the third portions 33 adjacent to each other in the vertical height direction of the lip member 3 is a part of the second portion 32. In FIG. 4B, the second portion 32 is formed between the region of the width La located between the first and third portions 31 and 33 and the third portion 33 in the vertical height direction. And two regions including a region having a width Lb larger than the width La. One or more recesses 34 are formed on one side of the third portion 33. By forming the concave portion 34 as described above, the third portion 33 can be more easily elastically deformed and can be a lightweight portion. In the drawing, a plurality of relatively small recesses 34 are formed in the third portion 33. However, according to such a configuration, a plurality of relatively small recesses 34 are provided as compared with the case where only one relatively large recess 34 is provided. There is an advantage that the total area of the lip member 3 with respect to the garnish 2 can be increased while the total volume of the recesses 34 is increased (the portion that separates the recesses 34 becomes the joint).

  As shown in FIGS. 2 and 3, in the present embodiment, a seal member 9 is bonded to the inside of the other edge 2 b of the garnish 2. Unlike the lip member 3 described above, the seal member 9 has a thin strip shape with a substantially constant overall thickness. This is because the other panel 15 is interposed inside the edge 2b, the width of the gap opening inside the edge 2b is narrow, and the clip 6 is located at a position close to the other edge 2b. Therefore, even if the seal member 9 is not formed in the form of the garnish 2 described above, the rigidity feeling in the vicinity of the end edge portion 2b is large.

  Next, the operation of the above-described structure A of the garnish attachment portion of the vehicle will be described.

  First, the end opening 7a of the gap 7 between the garnish 2 and the side outer panel 10 is closed by the first portion 31 of the lip member 3, and the inside of the end opening 7a is unsightly from the outside. It is possible to make it invisible in the state. On the other hand, since the thickness t3 of the third portion 33 of the lip member 3 is larger than the thickness t2 of the second portion 32 and close to the width Wb of the gap 7, as described above, the end of the garnish 2 Even if the portion near the edge 2a is pressed from the outside, the third portion 33 immediately generates a reaction force against the pressing force, so that the portion near the edge 2a is not greatly depressed, and the garnish 2 can be effectively enhanced.

  On the other hand, the lip member 3 has a configuration in which the second portion 32 exists between the first portion 31 and the third portion 33. When the lip member 3 is bonded to the garnish 2, The second portion 32 and the third portion 33 can be used as an adhesive surface for the garnish 2. Therefore, it is possible to increase the bonding area of the lip member 3 and prevent the lip member 3 from being unintentionally displaced. Since the thickness t2 of the second portion 32 is reduced, the volume of the lip member 3 can be reduced. Therefore, the raw material for molding the lip member 3 can be reduced, the manufacturing cost can be reduced, and the weight can be reduced. Further, in the present embodiment, since the third portion 33 having a large thickness t3 is partially provided on the lip member 3, it is possible to further promote reduction of raw materials and weight reduction of the lip member 3. Is possible.

  FIG. 5 shows another embodiment of the present invention. In the figure, the same or similar elements as those of the above embodiment are denoted by the same reference numerals as those of the above embodiment, and redundant description is omitted.

The lip member 3 </ b> A shown in FIG. 5 is formed in a state where the third portion 33 is continuously connected and extended over substantially the entire length of the lip member 3 in the longitudinal direction. The recesses 34 formed in the third portion 33 also extend in series in the same direction.
In the present invention, the third portion 33 can be configured as in the present embodiment. According to such a configuration, the gap 7 between the side outer panel 10 and the garnish 2 can be partitioned by the third portion 33, the region closer to the end opening 7 a than the third portion 33 and its There is an advantage that air circulation that causes noise or the like can be prevented from occurring between the two regions with the opposite region.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the structure of the garnish mounting portion of the vehicle according to the present invention can be variously modified within the scope intended by the present invention.

In the above-described embodiment, the recess 34 is formed in the third portion 33 of the lip member 3, but the recess 34 may not be formed. The lip member 3 is preferably an elastic body, but its specific material is not limited.
In the above-described embodiment, the garnish 2 provided in the C pillar is taken as a specific example, but the present invention is not limited to this. The panel as used in the present invention may be a panel as a vehicle body constituent member, and is not limited to a panel as a vehicle body exterior material, but may be a panel as an interior material. The garnish should just be provided so that the outer surface of such a panel may be covered, and the specific attachment method etc. are not limited. The lip member may be configured to be bonded to the panel instead of being bonded to the garnish.
