Abstract

PURPOSE:To prevent parts from interfering with a reinforce during car crash by coating the peripheral section of an aperture for mounting the parts formed on the reinforce with a part of the shock absorbing body of a resin bumper. CONSTITUTION:When a bumper outer layer 5 is deformed during car crash, a turn signal lamp 2 fixed on the bumper outer layer 5 is moved backward. At this time, the outer cylindrical body 8 of the turn signal lamp 2 is made to touch a soft shock absorbing body 4, for prefection and prevented from interfering with a reinforce 3. As a result, the bumper is not liable to be damaged.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resin bumper structure, and more particularly to an improvement in the resin bumper structure that allows parts to be attached to a portion of the resin bumper.

For example, as shown in FIGS. 1 to 3, a conventional resin bumper O structure of this type is used as a part to be attached to a resin bumper 1 on the 7-ont side, and is used as a turn signal lamp 2.21 as a direction indicator light. Taking as an example a case where the am bumper 1 is attached to both ends of the resin bumper 1 in the longitudinal direction, the am bumper 1
As shown in FIG. 2, a shock absorber 4 made of a molded product of foamed foam is placed on the front side of the reinforcement member, which is a pump member with a substantially rectangular closed cross-sectional structure made of a metal that reduces rigidity. A bumper skin 5 [, which has a substantially U-shaped cross section and is made of a polypropylene molded product or the like that can deform in accordance with the deformation of the impact absorber 4, is provided on the impact 1 so as to cover the impact member 4. 6, the entire tree skin bumper 1 is constructed, and the turn signal lamp 2 is further constructed.
As shown in FIG. 3, a recess s6 in which the turn signal lamp 2 is housed is formed in the bumper skin 5, and the bottom [1
A retaining hole 9 into which the outer cylindrical body 8 of the turn signal lamp 2 is fitted and fixed is bored in the outer cylinder 7, while an outer shell is provided in the skin shock absorber 4 and the reinforcement 6 at a rear position corresponding to the retaining hole 9. In order to prevent interference with the cylindrical body 8, the outer cylindrical body 8 is provided with large-diameter openings 10° and 11, respectively.
was wired from the openings 10 and 11 to the vehicle body side. Incidentally, peripheral edge 7 flanges 15a, 15b for reinforcement are formed at the edges of the openings 11a, 11b 114 of the front wall 16 of the reinforcement 6 and the vkl 114, respectively.

However, in such a conventional structure, as shown in FIG. , the outer cylindrical body 8 of the turn signal lamp 2 would interfere with the opening 11 and the peripheral edge of the l1tl wall 16 of the reinforcement 1, and there was a risk that the turn signal lamp 2 would be damaged.

Incidentally, such problems are not limited to the turn signal lamp 2, but also occur to all parts attached to the resin.

The present invention was developed based on the above-mentioned viewpoint, and the seventh object is to prevent parts from being damaged by preventing interference between parts attached to a resin bumper and reinforcement during a collision. It's about being relaxed. That is, as a means to achieve the above objectives, the present invention @ covers the 0 periphery of the parts mounting hole provided in the reinforcement with a shock absorber of a resin bumper, so that the Ks product does not interfere with the reinforcement in the event of a collision. The main purpose of this article is to avoid this.

Hereinafter, the present invention will be explained in detail based on an example shown in the attached circular.

The embodiment shown in FIG. 5 shows a case where a turn signal lamp 2 is attached as a part to a resin bumper 1, as in the conventional case.The basic structure of the resin bumper 1 in this embodiment is as follows. Similar to the conventional example shown in Figure 2, a reinforcement 6 made of foamed urethane, etc.
A Hayabusa absorber 4 is disposed, and a pamba skin 5 made of polypropylene or the like is fixed to the reinforcement 6 in a similar manner to the ms absorber 4161. In addition, in the mounting area of the turn signal lamp 2, the bumper skin 5 is similar to the conventional one.
is provided with a recess l16 for storing the turn signal lamp 2 and a retaining hole 9 for fixing the outer cylinder 8, and at the rear position of the # alignment hole 9 of the shock absorber 4 and the reinforcement 6, Apertures 10° and 11 are provided respectively to prevent interference with the outer cylinder 8, but unlike the conventional one, the peripheral flange 15m of the aperture 11m, which is generally #l11aK, of the reinforcement 6 is 1lErs absorber 4 The surface is covered by a covering portion 16 extending from the rear edge of the opening St reinforcement.

Therefore, as shown in FIG. 4, when the bumper skin 5 is deformed during a vehicle collision, the turn signal lamp 2 fixed to the bumper skin 5 moves away. 8 is protected by contacting the soft [r accident-affected body 4] and is prevented from interfering with the reinforcement 6 as in the conventional case, reducing the risk of damage.

Incidentally, the covering portion 16 of the shock absorber 4 is made of rain force 60.
The peripheral 7 flange 15aK may be fixed to the surface of the peripheral flange 15a, but it may be fixed to the peripheral 7 flange 15aK using an adhesive or the like, or the AT coating 16 may be attached to the peripheral flange 15m after the peripheral flange 15m.
The member 40 may be fixed so as to be wrapped around a part of the member 40. In addition, in the above ml example, Reinforce 5011
Covering portion 16 covers the edge of opening 11ajii of 1111t5i1.
We explained the case where the front hole 111311 and the rear 114a m hole 11 have +peripheral edge S.
In the above implementation example, the turn signal lamp 2 attached to the front bumper was explained as a part attached to the 411 skin bumper 1, but this It goes without saying that the present invention is not limited to this, and can be applied, for example, to the case where a rear bumper or other vehicular S product is attached to a resin bumper.

As explained above, according to the resin bumper structure according to the present invention, the periphery of the opening for attaching companion parts formed in the reinforcement is at the periphery of the tree skin bumper III! Because it is covered by a part of the IK absorber, the parts attached to the resin pumper during a collision are protected by the *S absorber and do not interfere with the reinforcement. It becomes difficult.
