Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a bumper mounted on a front portion of a vehicle body of an automobile.

[0002]

2. Description of the Related Art Conventionally, as this kind of vehicle bumper, for example, as disclosed in Japanese Patent Application Laid-Open No. 10-35377, a bumper disposed at the front of the vehicle is located on the rear side of the vehicle body. 2. Description of the Related Art There is known a structure including a first bumper and a second bumper formed so as to cover the entire front side of the first bumper and having a lower rigidity than the first bumper. The second bumper includes a skin portion forming a design surface of a front end portion of the vehicle, and the skin portion and the first skin portion.
It is composed of a plurality of energy absorbing springs which are disposed apart from each other in the vehicle width direction between the bumpers.

[0003] In this system, when a collision is relatively small, such as when the collision partner is assumed to be a pedestrian, the impact to the collision partner is reduced only by the energy absorbing spring of the second bumper. In the event of a large collision, after the energy is absorbed by the second bumper, the intrusion of an obstacle into the vehicle body can be suppressed while absorbing the energy by the first bumper.

[0004]

By the way, generally,
As described above, when the collision partner is a pedestrian, the bumper at the height corresponding to the pedestrian's leg directly collides with the leg. In other words, a part of the bumper in the vehicle width direction absorbs the collision energy. However, in the conventional bumper, since the energy absorbing springs are arranged apart from each other in the vehicle width direction, the collision location is adjacent. When it was located between the matching springs, the impact could not be absorbed by the spring as intended.

The present invention has been made in view of the above circumstances, and an object of the present invention is to devise a structure of an energy absorbing portion provided on a rear side of a skin portion of a front bumper of a vehicle body. Therefore, even if an obstacle collides with any position of the bumper in the vehicle width direction, the collision energy is absorbed as intended and the impact on the obstacle can be sufficiently reduced.

[0006]

In order to achieve the above object, according to the present invention, a plurality of resin ribs are provided on an energy absorbing portion of a bumper so as to be spaced apart from each other in a vehicle width direction, and from a vertical direction. At a glance, at least some of the adjacent ribs overlapped.

Specifically, according to the first aspect of the present invention, an energy absorbing portion provided at a front portion of the vehicle body so as to extend in the vehicle width direction and absorbing collision energy with an obstacle, and a skin portion covering the front thereof are provided. It is assumed that the vehicle is equipped with a bumper.
In the energy absorbing portion, a plurality of resin ribs extending at least in the vehicle longitudinal direction are provided apart from each other in the vehicle width direction, and the plurality of ribs are at least on the left side or the right side when viewed from the vehicle vertical direction. The configuration is such that a part thereof is inclined so as to overlap with an adjacent rib.

According to this configuration, in the energy absorbing portion of the vehicle bumper, the ribs juxtaposed in the vehicle width direction are provided.
When viewed from the vehicle vertical direction, at least a part of the left side or right side is inclined so as to overlap each other, so when an obstacle collides with the front part of the car, this obstacle collides with any part in the vehicle width direction. Even so, the impact is directly input to one of the ribs and absorbed, whereby the impact on the obstacle can be mitigated as intended.

According to a second aspect of the present invention, in the first aspect of the invention, a bumper reinforcement is provided at a rear side of the energy absorbing portion. Thus, when an obstacle collides with the front of the vehicle, the entire energy absorbing portion is prevented from moving rearward by the bumper reinforcement, and the ribs of the energy absorbing portion are surely crushed. Thus, the collision energy can be more reliably absorbed.

According to a third aspect of the present invention, in the second aspect of the present invention, each of the ribs of the energy absorbing portion is inclined so that at least a portion on the left side or the right side thereof when viewed from the vehicle longitudinal direction overlaps with the adjacent rib. It is assumed that

Since the ribs of the energy absorbing portion are inclined so as to overlap each other when viewed from the front and rear direction of the vehicle, when an obstacle collides with the front portion of the vehicle, the rib is directly impacted. The rib and the rib adjacent to the rib are deformed so as to overlap each other, and the collision energy is dispersed and absorbed by relatively many ribs. As a result, the energy absorbing portion can be prevented from remaining uncrushed, and the collision energy can be substantially uniformly and sufficiently absorbed by the plurality of ribs regardless of the collision position in the vehicle width direction.

According to a fourth aspect of the present invention, in the third aspect of the invention, the energy absorbing portion includes a plurality of ribs that surround and hold the plurality of ribs both vertically and rearwardly, and further include a holding member opened to the front of the vehicle body. I do. With this, while the rib is securely held by the holding member, when the obstacle collides with the front part of the vehicle, the holding member opened to the front of the vehicle body is easily deformed, so that absorption of the collision energy by the rib is prevented. Nothing.

That is, the rib is inclined so that the lower side of the rib 34 is located on the left side of the vehicle body, and the rear side of the rib 34 is located on the left side of the vehicle body. In addition, as shown in FIG. 10, the degree of the inclination is such that, when each rib 34 is viewed from above and below, a part located on the right side of the rib 34 overlaps a part located on the left side of the rib 34 on the right side of the vehicle body. As shown in FIG. 9, the portion located on the right side of the rib 34 when viewed from the front-rear direction of the vehicle body is set to overlap with the portion located on the left side of the rib 34 on the right side of the vehicle body. .

Next, the energy absorbing action by the deformation of the rib when an obstacle collides with the bumper 1 will be described with reference to FIG. Note that FIG. 11 shows B in FIG.
FIG. 4 is a cross-sectional view taken along a line B, in which the state of each rib 34 after the collision is indicated by a two-dot chain line.

As shown by an arrow in FIG. 1, first, when an obstacle collides with the bumper face 4, an impact acts on the energy absorbing portion 7 disposed behind the obstacle. Here, since the energy absorbing portion 7 is held by the cross member 23 of the bumper reinforcement 6 from the rear of the vehicle body, the energy absorbing portion 7 is reliably prevented from retreating, and the ribs 34, 34,. Since the ribs are held by the portions 33, the positioning of the ribs 34 with respect to the channel portion 33 is ensured, so that the collision energy can be applied to the ribs 34 as intended.

Since the rib 34 subjected to the impact is held by the channel portion 33 whose front side is open, the upper edge portion and the lower edge portion surely break from the front end. At this time, since the ribs 34, 34,... Are inclined such that the front end side is located on the right side of the vehicle body with respect to the direction in which the collision energy is received, the ribs 34 are displaced largely toward the right side of the vehicle body. The ribs 34 are bent from the rear end, and the collision energy is absorbed by the breaking and bending deformation of each rib 34. Due to the breakage of the ribs 34, 34,..., The connection of the upper wall 35 and the lower wall 36 of the channel portion 33 by the ribs 34, 34,. Since the channel portion 33 is bent upward and downward with a low load, the channel portion 33 does not hinder the absorption of collision energy, and the deformation of the channel portion 33 prevents the entire energy absorbing portion 7 from remaining uncrushed. A sufficient deformation stroke is ensured.

For example, when it is assumed that the obstacle is a pedestrian, the bumper 1 collides with the leg of the pedestrian. , 34 partially overlap each other, at least one of the ribs 34 is directly subjected to a collision load. As a result, the collision energy is reduced to the rib 3
4 absorbs as intended, and the impact on the obstacle is sufficiently reduced.

Since the ribs 34, 34,... Overlap as described above when viewed from the front-rear direction of the vehicle body, the ribs 3 which are directly impacted are deformed in the process of being deformed.
4 transmits and disperses the collision energy also to the rib 34 on the right side, so that even if the obstacle collides with any position in the vehicle width direction, the plurality of ribs 34, 34,
... absorbs the collision energy. The plurality of ribs 34, 34,.
Are bent in the same direction so as to overlap with each other, so that the energy absorbing portion 7 is reliably prevented from remaining uncrushed and the deformation stroke is sufficiently secured.
In this manner, the ribs 34, 34,... Having a predetermined degree of inclination and thickness are bent so as to absorb energy, so that the ribs 34 are designed in comparison with the energy absorption characteristics due to, for example, crushing deformation of urethane foam. It is possible to stably obtain the following characteristics.

Therefore, in the first embodiment, the energy absorbing portion 7 is provided so as to extend over both ends of the cross member 23 of the bumper reinforcement 6 in the vehicle width direction, and the ribs 34, 34, Are formed so as to overlap each other when viewed from the vertical direction and the front-rear direction of the vehicle body. Therefore, even if the obstacle collides with the bumper 1 at any position in the vehicle width direction, the energy of the collision is aimed at. The energy absorption portion 7 can be suppressed from remaining crushed while absorbing the energy uniformly and substantially uniformly, and a sufficient deformation stroke can be ensured. As a result, the impact on the obstacle can be reliably reduced.

The lower bumper reinforcement 51 includes a channel portion formed so as to extend substantially at both ends in the vehicle width direction of the lower bumper reinforcement 51, and a plurality of ribs arranged in parallel in an inclined state inside the channel portion. The lower energy absorbing portion 54 configured as described above, when attached to the lower bumper reinforcement 51, is positioned so as to overlap the upper energy absorbing portion 7 when viewed from above and below.

When an obstacle collides with the bumper 1, first, an impact acts on the energy absorbing portions 7, 54 located on the upper side and the lower side, respectively. As described in the first embodiment, the plurality of ribs 34, 34,.
Energy is absorbed by breaking from 3 and bending. That is, for example, assuming that the collision partner is the pedestrian's leg, the upper and lower energy absorbing portions 7 and 54 collide with the vicinity of the knee of the pedestrian's leg and the lower part thereof, and the energy is absorbed. Will be absorbed by this,
The impact can be dispersed and sufficiently mitigated.

Further, since the lower energy absorbing portion 54 collides with the lower portion of the pedestrian's leg to rub it, the pedestrian is scooped up and the impact force acting on the leg is reduced. The effect is also obtained.

Therefore, in the second embodiment, as in the first embodiment, even if the obstacle collides with any position of the bumper 1 in the vehicle width direction, the collision energy is absorbed as intended and substantially uniformly. However, the deformation stroke can be sufficiently secured, and the impact on the obstacle can be reliably reduced. In addition, when the obstacle is assumed to be a pedestrian, the impact can be dispersed to each of the upper and lower portions of the pedestrian's leg, and the impact force acting on the leg can be increased by scooping up the pedestrian. Can be reduced.
