The lower part is tightened with a plurality of screws or bolts 104.

c. Problems to be Solved by the Invention However, in the above-described conventional automobile bumper, as shown in FIG. 6, when an impact force acts on the bumper, the bumper fascia 101 covering the surface is raised upward. There is concern that the grill, engine hood or headlight, turn signal, etc., located above it may be damaged, and that the bumper facer 101 itself may be cracked.

An object of the present invention is to solve the above-mentioned problems of the related art.

d. Means for Solving the Problems In order to solve the above-described problems, the present invention provides an engagement claw having a U-shaped cross section that opens forward, at the upper rear end of the bumper facer, At the lower end of
A flange is provided along the longitudinal direction, the bumper armature is formed in a closed cross section by welding an inner panel and an outer panel, and a flange is provided at an upper end portion of the bumper armature to engage with an engagement claw of the bumper facer. Is provided so as to project rearward, and the lower end of the bumper armature is fastened to the rear surface of the concave portion of the bumper facer.

e. Operation When an impact force acts on the bumper for an automobile according to the present invention, at least the upper portion of the bumper fascia moves rearward, and no significant deformation occurs in the bumper fascia.

d. Examples Hereinafter, examples of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a perspective view showing the entire vehicle using the bumper according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is an exploded view of the bumper according to the present invention. It is a perspective view.

In the figure, 1 is a vehicle body, 2 is a front bumper mounted in front of the vehicle body 1, 3 is a grill provided above the front bumper 2, 4 is a headlight, 5 is a direction indicator, and 6 is an engine. Food.

As shown in the sectional view of FIG. 2, the front bumper 2 is formed of a bumper facer 7 formed of a synthetic resin or the like covering the surface, and a urethane foam or a resin block inserted into the bumper facer 7. Energy absorbing member 8, and a bumper armature 9 for reinforcing the bumper fascia 7 and the energy absorbing member 8.

The bumper armature 9 is formed in a closed cross section by welding the inner panel 10 and the outer panel 11, and a flange 12 protruding largely rearward is formed above the bumper armature 9.

As shown in FIGS. 1 to 3, the bumper facer 7 has a recess 13 formed at a lower end of the energy absorbing member 8 along the longitudinal direction thereof. Are provided with a plurality of screws or bolts 14 as a lower fixing means for the bumper armature 9, and firmly fix the lower part of the bumper facer 7 and the lower part of the bumper armature 9.

On the other hand, on the upper rear end of the bumper facer 7, an engaging claw having a U-shaped cross section which opens forward and engages with a flange 12 formed to project rearward from the upper end of the bumper armature 9 is formed. 15 are formed. The engaging claw 15
As shown in FIG. 2, the bumper is first extended rearward so as to cover the flange 12, then wrapped around the flange 12 so as to be hooked, and extended again to the base of the flange 12. The upper part of the facer 7 is mounted on the upper part of the bumper armature 9 so as to be slidable in the front-rear direction.

In the drawing, reference numeral 16 denotes a cutout groove provided on the energy absorbing member 8 for improving deformability, and reference numeral 17 denotes a rib for reinforcing the bumper armature 9.

In the bumper for an automobile according to the present invention, the upper portion of the bumper facer 7 and the upper portion of the bumper armature 9 are attached so as to be slidable in the front-rear direction as described above.
As shown in FIG. 4, when an impact force acts on the bumper 2, the bumper facer 7 moves rearward without being deformed upward, and the grill 3, the engine hood 6, or the headlight located above the bumper facer 7 moves. 4. The turn indicator 5 and the like are not damaged, and the bumper facer itself does not crack.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention.

For example, in the above embodiment, the bumper fascia 7
Is formed by forming a flange 12 extending rearward on the bumper armature 9 and forming an engaging claw 15 for engaging with the flange 12 on the bumper facer 7, but is not limited to this. For example, a long hole extending in the front-rear direction may be formed in either the bumper armature 9 or the bumper facer 7, and both may be attached using the long hole.

e. Effects of the Invention According to the vehicle bumper according to the present invention, the following effects can be obtained.

There is no need to consider damage due to deformation of the bumper fascia such as the grill, engine hood or headlights, direction indicators, etc. located above the bumper, so that repair costs can be reduced and design flexibility can be improved. Can be improved.

In addition, when an impact force acts on the bumper from the front, the energy absorbing member is deformed. In addition, the lower part of the bumper fascia deforms to absorb the impact force. The bumper fascia moves rearward without being deformed upward, and does not damage the grill, engine hood, headlights, direction indicators, and the like located above it. Also, no cracking of the bumper fascia itself occurs.

Further, if the mounting structure is provided on the upper part of the bumper fascia as in the embodiment, the number of screwing or bolting steps can be reduced, and the productivity can be improved.
