Description

  The present invention relates to a fender side protector. Specifically, the present invention relates to a fender side protector that is provided, for example, in a front pillar outer portion that constitutes a side outer panel of a vehicle body, and is used for the purpose of improving a sound insulation effect between a vehicle interior and the outside.

Generally, a side body structure of a vehicle such as an automobile has a configuration in which a side outer panel is formed in a shape that fits around an opening / closing door for getting on and off. Specifically, the side outer panel is integrally formed as a frame shape in which, for example, a front pillar outer portion, a roof rail outer portion, a rocker (also referred to as a side sill) outer portion, and a center pillar outer portion are joined together. Here, in Patent Document 1 described later, an example of the structure of the side outer panel is shown.
By the way, in recent vehicle body structures, a structure is adopted in order to improve the sound insulation effect with respect to the outside of the vehicle interior. Specifically, for example, among the side outer panels, a front pillar outer portion arranged as a position between the engine side portion which is a noise generation source is provided with a curved plate-shaped protector. This protector (hereinafter referred to as a fender side protector) is formed as a resin molded product such as polypropylene or nylon, and is attached to the front side wall surface (the wall surface on the side visually recognized by the occupant) of the front pillar outer portion.
Specifically, the fender side protector is provided with a clip at a predetermined position for attachment to the front pillar outer portion. The front pillar outer portion is formed with a mounting hole for inserting the clip. Therefore, the fender side protector can be attached to the front pillar outer portion by inserting the clip into the attachment hole.
Further, the fender side protector is attached with a seal member for imparting a sealing property to the attachment state with respect to the front pillar outer portion. This sealing member is formed of a foam molded product such as an eptosealer, and is bonded along the peripheral edge of the protector body formed in a predetermined curved plate shape. It is arranged as a standing shape. Therefore, when the fender side protector is attached to the front pillar outer portion, the seal member is compressed and deformed so as to compensate for the gap between the two. Thereby, a fixed sealing property can be given to the attachment state of a fender side protector. In addition, the soundproofing performance by the fender side protector can be improved.

As shown in FIGS. 2 and 3, the former protector body 20 </ b> A is formed in a shape that matches the front side wall surface shape (complex shape) of the front pillar outer portion F. Further, clips 23 for inserting into the mounting holes h (see FIG. 3) formed in the front pillar outer portion F described above are located at two positions on the back side of the protector main body 20A (the right side in the drawing shown in FIG. 3). Is provided. The clip 23 has a shape in which a side surface portion of the clip main body projects outward in the radial direction and is partially hollowed out, and is formed so as to be elastically deformable inward. Therefore, the fender side protector 10 is held in a state of being attached to the front pillar outer portion F by inserting and engaging the respective clips 23 into the attachment holes h, as well shown in FIG.
As shown in FIG. 2, the latter seal member 30A is formed integrally with the protector body 20A as a shape along the peripheral portion 21a of the protector body 20A. Specifically, as well shown in FIGS. 3 and 4, the seal member 30 </ b> A is formed by two-color molding (multi-color molding) of an elastomer resin having thermoplastic foaming properties on the protector body 20 </ b> A. Yes. Therefore, the seal member 30A is bonded to the protector body 20A with a strong adhesive strength. The seal member 30A may be integrally formed endlessly along the periphery of the protector body 20A, or a plurality of end-shaped members may be formed. Thus, the seal member 30A is disposed as a shape rising from the curved plate surface along the peripheral portion 21a of the protector body 20A (see FIGS. 3 and 4). In FIG. 3, a portion indicated by a two-dot chain line for the seal member 30A indicates a state (free state) before the seal member 30A is compressed and deformed.

Then, the usage method of the fender side protector 10 of a present Example is demonstrated.
First, the protector body 20A of the fender side protector 10 is aligned with the position of the front side wall surface of the front pillar outer portion F, and each clip 23 is inserted into the mounting hole h. Thereby, the fender side protector 10 is hold | maintained as the state attached to the front pillar outer part F. FIG. At this time, the seal member 30A disposed as a standing shape at the peripheral portion 21a of the protector body 20A is configured to compensate for the gap between the attached fender side protector 10 and the front pillar outer portion F. To compressive deformation. Specifically, since the sealing member 30A is formed of a foamable elastomer resin, it is in a state where it is easily deformed (easily bent) and has a good shape following property conforming to the shape of the front pillar outer portion F. Show. Thereby, a fixed sealing property can be given to the attachment state of the fender side protector 10. In addition, the soundproofing performance of the fender side protector 10 can be improved.

Thus, according to the fender side protector 10 of the present embodiment, the sealing member 30A is formed integrally with the protector main body 20A, so that a separate bonding operation is not required. In particular, when the protector main body 20A is formed in a complicated shape, the troublesome work of sequentially bonding the seal member 30A along the peripheral edge of the complicated shape becomes unnecessary. Therefore, it is possible to reduce the work man-hours required for attaching the seal member 30A as compared with the conventional technique. Further, by forming the seal member 30A by two-color molding as in the present embodiment, it can be disposed in a state where the adhesive strength with the protector main body 20A is increased.
Furthermore, since the seal member 30A is a molded product made of an elastomer resin, it can exhibit a good sealing function during use. Further, since this elastomer resin has foaming properties, the seal member 30A is easily bent and exhibits good shape followability in accordance with the shape of the front pillar outer portion F. Therefore, the sealing performance by the seal member 30A can be improved.

Then, the fender side protector 11 of Example 2 of this invention is demonstrated using FIG. FIG. 5 is a view schematically showing the cross-sectional shapes of the seal member 30B and the protector main body 20B of the fender side protector 11. As shown in FIG.

At this time, the sealing member 30B formed of an elastomer resin and having the hollow portion 31b is in a state of being easily deformed (easily bent), and exhibits a good shape following property conforming to the shape of the front pillar outer portion F. . Thereby, a fixed sealing property can be given to the attachment state of the fender side protector 11. In addition, the soundproofing performance by the fender side protector 11 can be improved.

  Thus, according to the fender side protector 11 of the present embodiment, the seal member 30B is formed as a hollow cross-section having the elastomer resin having the hollow portion 31b. Good shape followability according to the shape of F is shown. Therefore, the sealing performance by the sealing member 30B can be improved.

Then, the fender side protector 12 of Example 3 of this invention is demonstrated using FIG. FIG. 6 is a view schematically showing the cross-sectional shapes of the seal member 30C and the protector main body 20C of the fender side protector 12. As shown in FIG.
In the present embodiment, the description of the same configuration and operation as those of the fender side protectors 10 and 11 of the first embodiment or the second embodiment will be omitted, and different configurations will be described in detail.

The fender side protector 12 of the present embodiment is formed in a long shape as a shape along a protector body 20C formed as a curved plate shape and a peripheral portion 21c of the protector body 20C, as well shown in FIG. The sealing member 30 </ b> C (formed of an elastomer resin having foamability) is formed as a separate body. Hereinafter, the configuration of each unit will be described in detail.
In the former protector main body 20C, as well shown in FIG. 6, concave portions 22c that can be engaged with the convex portions 33c of the seal member 30C are formed on the front and back surfaces of the peripheral portion 21c. Here, the convex portion 33c and the concave portion 22c correspond to the engaging means of the present invention.
As shown in FIG. 6, the latter seal member 30C is formed in advance as a shape along the peripheral portion 21c of the protector body 20C as a separate body from the protector body 20C. In addition, a fitting slit 32c that can be fitted to the thick portion of the peripheral portion 21c of the protector body 20C is formed in the inner peripheral portion of the seal member 30C. Further, a convex portion 33c that can be engaged with the concave portion 22c formed in the peripheral portion 21c of the protector body 20C is formed in the fitting slit 32c. Therefore, by fitting the fitting slit 32c formed in the inner peripheral portion of the seal member 30C into the peripheral portion 21c of the protector body 20C, the seal member 30C is fitted into the thick portion of the peripheral portion 21c (FIG. 6). (Refer to the two-dot chain line portion indicated by). At this time, the concave portion 22c formed in the peripheral portion 21c of the protector body 20C and the convex portion 33c formed in the fitting slit 32c of the seal member 30C are engaged with each other.
In addition, when a part of the seal member 30C is fitted into the protector body 20C as described above, the other parts can be fitted relatively easily. That is, when a part of the seal member 30C is fitted, a portion adjacent to this portion (a portion adjacent to the front or back direction of the paper surface shown in FIG. 6) is a mechanical property (shape followability) of the elastomer resin. ) Is elastically positioned at the fitting position following the fitted portion. Further, since the seal member 30C is formed in advance as a predetermined peripheral shape along the periphery of the protector main body 20C, when the fitting is performed, the sealing member 30C is positioned at the fitting position. Therefore, even when the protector main body 20C is formed in various shapes such as a complex shape, the portion into which the seal member 30C is fitted can be fitted only by applying a force from the side toward the protector main body 20C. . Thereby, the fitting slit 32c of the seal member 30C is fitted to the thick portion of the peripheral portion 21c of the protector body 20C. Specifically, the protrusion 33c formed in the fitting slit 32c and the concave portion 22c formed in the peripheral portion 21c are engaged with each other.

  Next, the usage method of the fender side protector 12 is demonstrated. That is, the seal member 30C disposed as a standing shape at the peripheral portion 21c of the protector body 20C is compressed between the attached fender side protector 12 and the front pillar outer portion F so as to compensate for the gap therebetween. Deform. At this time, the sealing member 30C formed of an elastomer resin having foamability is in a state of being easily deformed by compression (easy to bend), and exhibits a good shape following property conforming to the shape of the front pillar outer portion F. . Thereby, a fixed sealing property can be given to the attachment state of the fender side protector 12. In addition, the soundproofing performance by the fender side protector 12 can be improved.

Thus, according to the fender side protector 12 of the present embodiment, the seal member 30C can be easily attached even when the protector body 20C is formed in various shapes such as a complex shape. Therefore, unlike the conventional case, the troublesome work of sequentially bonding the seal member 30C along the periphery of the protector body 20C formed in a complicated shape is unnecessary. That is, the number of work steps required for attaching the seal member 30C can be reduced as compared with the conventional technique.
Furthermore, the peripheral part 21c of the protector main body 20C and the fitting slit 32c of the seal member 30C can be fitted in a state in which they are engaged with each other by the engaging means having an uneven shape. Therefore, the fitted state of the seal member 30C can be made suitable.

Although the embodiment of the present invention has been described with reference to three examples, the present invention can be implemented in various forms in addition to the above-described example.
That is, in Example 1 to Example 3, in order to facilitate bending of the seal member and improve shape followability, the seal member is made of foamed elastomer resin (Examples 1 and 3), Although the cross-section is formed in a hollow shape (Example 2), other than that, the seal member can be easily bent by means of reducing rigidity, for example, by providing a partial punch through the cross-section. Also good.
Moreover, although the fender side protector was shown to be attached to the front pillar outer portion, it may be attached to a portion constituting another side outer panel in accordance with the purpose of use.
Moreover, although the sealing member has been shown to be disposed on the protector body formed as a curved plate, it goes without saying that the seal member may be disposed on a flat plate-shaped protector body.
