Description

[Detailed Description of the Invention] This invention relates to an automobile bumper, and particularly to a bumper side mounting structure of a shock-absorbing bumper.

Conventionally, impact-absorbing bumpers used in automobiles are attached to the front and rear of the vehicle body via shock absorbers, etc., and both ends are generally covered with side protectors made of elastic material that extend all the way to the sides of the vehicle body. It is installed.

In this case, in order to prevent damage to the vehicle body due to interference between the side protector and the vehicle body due to vibration or the like, the end portion of the side protector is fixed to the vehicle body via a bracket with bolts and nuts.

However, in a shock absorbing bumper device,
Fixing the end of the side protector with bolts and nuts as described above has the disadvantage that the bumper side deforms when impact is absorbed.For this reason, the bracket interposed between the side protector and the vehicle body is In this case, the brackets tend to slide easily and become misaligned, making installation difficult, and the side protectors also tend to slide. It had drawbacks such as poor workability due to the narrow gap between it and the vehicle body.

This idea was devised in view of these drawbacks, and while a mounting part with a long hole is integrally molded on the inside of the bumper side, it is bent from the base part attached to the vehicle body side and engaged with the long hole. A bracket is provided with a retaining portion formed therein, and the engaging portion of this bracket is positioned by a partition wall provided in the middle of the elongated hole to fix the base portion to the vehicle body. This is cut or expanded and made to slide on the side of the bumper.It prevents vibrations on the side of the bumper, simplifies installation, and when absorbing impact, prevents deformation of the side of the bumper by sliding. This is what I did.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a partial perspective view of the bumper device, in which 1 is a bumper body, which is attached to a vehicle body frame 3 via a shock absorber 2. As shown in FIG.

At the end of the bumper body 1, a side protector 4 made of an elastic material such as rubber or synthetic resin is fixed with bolts 5 and buttoned. 6, 6 are integrally molded, and elongated holes 7, 7 are formed in the mounting portions 5, 5 in the longitudinal direction.

On the other hand, as shown in FIGS. 2 and 3, upper and lower engaging portions 9b, 9b formed by bending from the base 9a of a bracket 9 attached to the vehicle body 8 are engaged with the elongated holes 7, 7, respectively. The engaging portions 9b, 9b and the elongated hole 7
, 7 and on the front side of the engaging portion, and the base 9a of the bracket 9 is fixed to the vehicle body 8 with bolts 11.

Note that 12 is a NAND welded to the base.

To attach the bumper side configured as described above, first, the attachment parts 6, 6 integrally formed on the side protector 4 are attached.
The engaging parts 9b, 9b of the bracket 9 are fitted into the elongated holes 7, 7, and the bracket 9 is positioned at the partition wall 10°10, and the bolt 11 is inserted from inside the vehicle body 8.
The side protector 4 is fixed to the vehicle body 8 by screwing with a nut 12 welded to the bracket 9.

If an impact force P is applied to the bumper body 1 from the front of the vehicle on the bumper side mounted in this way, the engaging portions 9b, 9b of the bracket 9 mounted on the vehicle body 8
Then, the partition wall 10.10 located on the front side of the engaging part is cut, and the side protector 4 slides rearward together with the bumper body 1 to prevent deformation of the bumper side, and the shock absorber 2 absorbs the impact force. After that, the long holes 7, 7 of the side protector 4 are guided by the engaging portions 9b, 9b of the bracket 9, and return to the front together with the bumper body 1.

In the above embodiment, the engaging portion 9b of the bracket 9.

Although the mounting portions 9b are provided vertically on the outside, they may be formed on the inside vertically as shown in FIG. Just one is enough.

Various modifications can be made to the partition walls io and io,
If the grooves 13 are provided as shown in FIGS. 6a and 6b, the engaging parts 9b and 9b of the bracket 9 will push apart the partition walls 10 and 10, allowing the side protector 4 to slide rearward. Sliding becomes easier.

In addition, although the above embodiment described the front bumper side, the rear bumper side also has the partition wall 10.10.
If it is located on the rear side of the bracket 9, it can be implemented in the same manner as described above.

As described above, according to the present invention, a mounting portion with a long hole is integrally molded on the inside of the bumper side, and an engaging portion that is bent from the base portion attached to the vehicle body side and engages with the long hole. A bracket is provided, and the engaging portion of this bracket is positioned by a partition wall provided in the middle of the elongated hole, and the base portion is fixed to the vehicle body, and when absorbing shock, the partition wall is cut or expanded to form a bumper. Since the sides are designed to slide, the bracket is positioned on the bulkhead and can be easily installed from the inside of the vehicle with a single bolt without causing any misalignment. In addition, when absorbing a shock, the side protector easily cuts or pushes the partition wall apart and slides, thereby preventing deformation of the bumper side.
