Abstract

PURPOSE:To prevent an energy absorber from deformation caused by a downward load acting on the upper portion of a fascia embracing the energy absorber, by supporting the upper and lower rear portions of said energy absorber on the horizontal racks formed at the upper and lower ends of an armature. CONSTITUTION:An armature 10 connected to a bumper stay is formed by a member 11 having an approximately L-shaped section and a step-wise folded member 12 to provide a closed sectional structure. Then, an energy absorber 2 is arranged at the front side of the member 12. In this case, the energy absorber 2 is formed with the rear surface having identical shape with the member 12. The upper rear side 2a and the lower rear side 2b are mounted respectively on the upper horizontal rack 12a and the lower horizontal rack 12b of the member 12. And the whole periphery except for the rear side of the energy absorber 2 mounted on said respective racks 12a, 12b is embraced with a fascia 4 the upper and lower ends 4a, 4b of which are secured fixedly to an armature 10 through bolts-nuts 3.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a bumper #I WC and relates to a bumper structure that can maintain the quality of the bumper over time.

As a conventional bumper Wa, structures as shown in FIG. JiI41 and FIG. 2 are known.

The Bamba Il structure with a hole in Figure @1 has one tree or an energy absorber 2t formed in a honeycomb shape arranged in the armature of the armature 1, which is often fitted with a closed-face fusuma structure. The stiffness energy absorber 2t, the upper F end of which is fixed with bolts and nuts 3 in the vertical direction of the armature 1, is a mm-thick wire (
It is made by holding it in Sha 4.

The bumper construction company, engine room (1) shown in Figure 2.
Improve the efficiency of introducing outside air into the armature (armature 1'
A horizontal hole 55t is formed on the upper side of the rear side of the energy absorber 2.
2a, and attach the clip 3 to the armature 1.
#The above energy absorber 2t with stopper 7e 1 sear 4
-It is something that I have embraced.

However, in such conventional bumper structures, the upper interior 2b of the energy absorber 2 is
Since the energy absorber 2 is only supported by the upper part of the fascia 4, the energy absorber 2 is moved downward across the smooth #Il facing wall 1a of the armature 1. The problem was that the appearance quality of the bumper as a whole was impaired, and the energy absorption characteristics in the event of a collision were reduced.

This invention was devised in view of these four conditions, and its purpose is to allow the energy absorber to easily absorb downward loads without deteriorating its energy absorption performance against 41# sudden loads. It is an object of the present invention to provide a bumper structure that can maintain an appearance quality of 1 over time without deformation.

In order to achieve this objective, in the present invention, an energy absorber is disposed on the forward side of the armature, and this energy absorber is placed on the upper and lower surfaces of the armature.
The upper and lower ends of the above-mentioned armature of the bumper, which is held by 7 wheels to which the i1 part is fixed, are bent to form a horizontal shelf part, and energy absorbers t- are attached to the upper and lower horizontal shelf parts.

Next, the present invention will be explained in detail based on the embodiments shown in FIG. 3 and below.

FIG. 3 shows a bumper structure according to a first embodiment of the invention.

In the Jin no Ii an, the I-macha 10 connected to the bread bursti (not shown) has a 111 ml L-shaped first
S material 11 and floor! ! The second member 1 is bent into an L shape.
2 to form a closed cross-sectional structure.

In the armature 10I, D-shaped member 12, configured in this manner, an energy absorbing body 2 formed in the form of a tree shield foam or honeycomb is disposed, and this energy absorption body 2 is disposed in the armature 10I; The rear part of the body 2 is connected to the armature 10
The outer shape of the second member 12 is the same as that of the second member 12, and the outer shape of the second member 12 is the same as the outer shape of the second member 12. 2ak is placed on the soil part horizontally 1mm12& of the second member 12, and its 'F surface s2b is placed on the lower horizontal shelf part 1 of the second member 12o.
It is placed on 2b. In addition, the lower horizontal 4 of the second member 12
The tip of the 11th part 12b is formed to have a short size so that the energy absorption performance of the bumper against electric power does not deteriorate.

In this way, the valley horizontal shelf portion 12a of the second member 12.

The entire energy absorber 2 except the rear side of the 12bK mechanically placed energy absorber 2 is held by the aJ-made fascia 4, and the upper and lower ends s41.4b of this 7a It is fixed to the armature 10.

Therefore, in the Bamba L# structure according to this example, even if the F-turn V wheel load G acts on the upper part of the fascia 4, the energy frame-1 & storage frame-2 will absorb all of the load G. Also, the F plane m2b of the energy absorber 2 is the same as the armature 1.
The lower horizontal 4m12b of the second member 12 of 0 and the fascia 4
Since it is supported by the absorber 2, it does not move in the F direction and move to -r, so the absorber 2 returns to the Ijit position.

The 4th figure and the 5th figure show the remains of the Bamba structure according to the second example of this older example.
, the armature 10k is formed with only fA2 mori 1z in order to improve the efficiency of outside air flow into the engine room, and the 2s.
Four parts 13 are placed at each space on the upper horizontal shelf 121) of the material 12.

Since this invention includes more than 100% force, even if 4 loads of 1F are applied to the old city of Bamba, it will not be deformed and will not be deformed outside the bumper! ! ! Quality can be maintained over time.
