Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile bumper molding mounting structure for mounting the bumper molding on the upper surfaces of both the reinforcement and the bumper body held on the front surface thereof. .

[Prior Art] FIG. 4a shows a conventional bumper molding 1 of this type, in which a bumper cover 2a, which is the upper surface of a bumper body 2 held on an upper surface 3a of a reinforcement 3 and a front step 3b of the reinforcement 3, is shown. The reinforcement is attached by inserting the lower bulge 5a of the clip 5 set on the back surface into the perforations 3c arranged on the upper surface 3a of the reinforcement.

As shown in Figure b, this clip 5 consists of a molding inner 1a whose seat portion 5b extends not only to the reinforcement top surface 3a but also to the bumper cover 2a and is folded back, and a molding inner 1b which is folded back from the rear end of the molding. It occupies the entire area of the cavity formed by.

[Problem that the invention attempts to solve]

Therefore, when the bumper body 2 is compressed and displaced to the position shown by the upper double-dashed line during a collision, the seat portions 5b of the bumper molding 1 and the clip 5 are also displaced, and in particular, the neck portions 5c thereof are deformed or damaged. There was a possibility.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a mounting structure for an automobile bumper molding in which the clip is unlikely to be damaged in the event of a bumper collision.

[Means to solve the problem]

In order to achieve this objective, the present invention has a circular shape in the lower cross section of the clip, which is held on the upper surface of the reinforcement and its front step, and has a bumper mold set on the back surface of the upper surface of the bumper body that is compressed in the event of a collision. In the mounting structure of an automobile bumper molding, which is installed by inserting the bulge into the perforations arranged on the upper surface of the reinforcement, a resilient bumper molding is integrally formed from a molding outer and a molding inner, and the molding inner is , the seat part of the clip is formed so as to be held between the molding outer, and a slit is formed in a portion located on the upper surface of the reinforcement into which a neck part between the seat part and the bulge part is inserted; It is characterized by being formed into a square shape that occupies only the upper surface of the reinforcement.

[Effect]

When the bumper main body is compressed and displaced during a collision, the bumper mold follows the clip without being restrained by the clip due to its elasticity because the clip seat part does not extend over the bumper main body, and the impact applied to the clip is reduced.

Since the clip seat is square and the bulge has a circular cross section, there is no directionality when setting it on the bumper molding.

[Example of idea]

1 to 3 show a mounting structure for a bumper molding 10 according to an embodiment of the present invention. This bumper molding 10 has elasticity, for example.
Mall outer 11 and mall inner 1 from SUS
This molding inner is formed in two layers by a molding inner 12a folded back from the front end side and a molding inner 12b folded back from the rear end side, and the part located in the center of the reinforcement upper surface 3a. A slit 12c is formed in the vertical direction. Moreover, the bumper molding 10 has its tip 1
2d is formed with a curved portion that comes into contact with the bumper cover 2a, and the molding outer 11 and the molding inner 12a
Edges 11a and 12e are formed in a portion located above the rear end surface 2b of the bumper cover 2a.

Reference numeral 15 denotes a clip, the seat portion 15a of which has a neck portion 15c that is connected to the slit 12c of the bumper molding 10.
By being inserted into the mold, the mold outer 11 and the mold inners 12a and 12b are sandwiched between them.
Further, the seat portion 15a is sized to be located only on the upper surface 3a of the reinforcement, and has a square shape as shown in FIG. 2.

The bumper molding 10 is constructed by inserting the clip neck portion 15c into the slit 12c from the end in the vehicle width direction and sliding it in order into the position of the perforation 3c, as shown in FIG. The bulge 15b is inserted into the perforation 3c of the upper surface 3a of the reinforcement to be assembled. The seat part 15a is square, and the bulge part 1
Since 5b has a circular cross section, it has no directionality and there is no problem of setting errors.

When the bumper main body 2 is compressed and displaced during a bumper impact, the portion of the bumper molding 10 placed on the bumper cover 2a elastically follows the bumper cover 2a while being released from the restraint by the seat portion 15a, and the molding inner 12a
The shearing force on the neck portion 15c is reduced. In particular, the bumper cover 2 at the molding tip 12d
a, and edges 11d and 12e are formed, the tip 12d rotates around the edges 11d and 12e, and the impact displacement is reliably absorbed by the front portions of these edges.

[Effect of idea]

As described above, according to the present invention, since the clip seat portion is located only in the reinforcement portion, the impact is absorbed by the elastic molding portion above the bumper body, and damage to the clip, especially the neck portion, is prevented from occurring.
In other words, the molding mounting portion on the bumper body can be enlarged, and the degree of freedom in molding design increases. Furthermore, by downsizing the clip seat and closing part of the molding space, the same clip can be used in common even if the molding width changes. Since the seat part is square and the bulge part has a circular cross section, there is no directionality and no missetting occurs.
