The present invention relates to an automobile bumper, and in detail, an air gap, which is a fine air bag, is formed in a predetermined shape and a predetermined structure in a bumper to reduce a collision impact of a vehicle. It's about the bumper.

Typically, bumpers mounted on the front and rear of the chassis frame are made of metal or urethane to alleviate the impact of front and rear collisions of automobiles. The latter is mainly used in recent years because it is easy to deform even in the light and light collision, because the inner plate with good elastic force has good shock absorption and deformation does not occur easily.

At this time, the urethane bumper is usually used to uniformly filled urethane rubber bar, if a predetermined shock absorbing means is added to the inside can increase the deformation displacement can increase the effect of the buffer.

Accordingly, an object of the present invention is to provide a bumper for a vehicle having a shock-absorbing structure that increases the effect of cushioning and restoring force after a collision by arranging the inside of a shock absorbing portion in a vehicle bumper in a predetermined shape and in a predetermined structure.

In order to achieve this object, the present invention provides a bumper mounted on the vehicle body at the foremost and rearmost parts of a vehicle to mitigate an impact caused by a vehicle collision; A bumper frame 10 made of metal formed at a predetermined curved surface R at both ends 10a of the vehicle body; And it is bonded to the bumper frame 10, and has a structure in which an air gap 11a, which is a minute air pocket is formed throughout the inside to increase the shock absorbing force therein, characterized in that the elastic material Provided is a vehicle bumper with a shock-absorbing structure.

At this time, in the bumper for mitigating the impact caused by the collision of the vehicle mounted on the vehicle body in the foremost and rear parts of the vehicle; Provided to the vehicle body is a metal bumper frame formed at a predetermined curved surface at both ends.

In this case, instead of bonding one shock absorber to the bumper frame, a front shock absorber and a rear shock absorber having an internal structure which increases shock absorbing force in front and rear of the bumper frame may be joined.

On the other hand, it is bonded to the bumper frame and has a structure in which an air gap, which is a small air bag is formed throughout the inside to increase the shock absorbing force therein, and a bumper for a vehicle of a shock-absorbing structure, characterized in that the elastic material In another embodiment, the buffer includes a blind plate in which no groove is formed; A vertical groove plate having a plurality of minute vertical air gaps formed to penetrate in the vertical direction; A horizontal groove plate in which a plurality of minute horizontal air gaps are formed to penetrate in the horizontal direction; No groove is formed and includes a front plate which extends up and down to form a cover portion; At least one of the blind plate, the vertical groove plate, and the horizontal groove plate may be laminated and bonded to each other to be integrally formed by being covered by a cover part of the front plate; The shock absorber provides a bumper for a vehicle having a shock-absorbing structure, characterized in that it can be configured as a front buffer and a rear shock absorber respectively bonded to the front and rear of the bumper frame.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a perspective view of a vehicle bumper equipped with one shock absorber.

The bumper frame 10 is detachably fixed to the vehicle body and is an iron plate made of a metallic material having elastic force, and both ends 10a of the bumper frame 10 are formed to have a predetermined curved surface. The shock absorber 11, which is bonded to the front of the bumper frame 10 and serves as a shock absorber, has an air gap 11a, which is a small air bag throughout its interior. The air gap 11a is arranged at regular intervals in the entire space of the shock absorber 11, so that even if a collision occurs in any part of the shock absorber 11, the amount of displacement that the shock absorber 11 may deform may be increased. .

2 shows a perspective view of a vehicle bumper equipped with two shock absorbers.

The bumper frame 1 has the same iron plate structure as that of FIG. 1, and the front shock absorber 12 and the rear shock absorber 22 are integrally formed at the front and the rear thereof, respectively. FIG. 2 is suitable for medium and large vehicles because the shock absorbing force is higher than that of FIG. 1 and the external dimensions and weight are also large.

If the air gap 11a as shown in FIG. 1 is formed inside the front shock absorber 12 and the rear shock absorber 22, the shock absorbing force can be further increased.

In this case, the bumper of FIG. 2 is formed in a separate structure as shown in FIG. 3 in consideration of the fact that the bumper of FIG.

FIG. 3 shows the detailed structure of FIG. 3, (a) is a perspective view of the internal laminate structure of the shock absorber, and (b) is an X-X sectional view of FIG.

In FIG. 3 (a), the cover is formed by vertically stacking plate 24 and horizontal groove plate 25 alternately stacked and joined in multiple layers between the blind plate 23 to extend the top and bottom of the front plate 26. It is formed integrally inside the portion 26a.

The vertical groove plate 24 is formed with a plurality of minute vertical air gaps 24a which are long penetrated in the vertical direction, and the horizontal groove plate 25 is formed with a plurality of minute horizontal air gaps 25a which are long penetrated in the horizontal direction. No air gap is formed in the blind plate 23 and the front plate 26.

In FIG. 3 (b), the blind plate 23, the vertical groove plate 24, and the horizontal groove plate 25 of FIG. 3 (a) are laminated and bonded to the front plate 26, and the lid portion 26a is used. You can see that it is wrapped. The vertical air gap 24a and the horizontal air gap 25a are staggered and joined to each other in a regular arrangement, respectively.

At this time, instead of forming the vertical air gap 24a and the horizontal air gap 25a on a separate plate as described above, it is also possible to form regularly on the same plate repeatedly.

In addition, the vertical air gap 24a and the horizontal air gap 25a may be attached to each other without a blind plate 23 with a slight opening so as to throttle, and the vertical air gap 24a and It is also possible that the horizontal air gap 25a is sealed between the blind plate 23 and the front plate 26 so as to have a strong buffering effect.

As described above, the present invention installs an air gap having a predetermined shape in the structure of the shock absorber attached to the bumper frame and the shock absorber absorbing the shock from the vehicle bumper and arranges it in a predetermined structure, thereby enhancing the effect of the shock absorbing and after the collision. Increasing resilience has the effect of maintaining the original state as possible.

Although the present invention has been illustrated and described with reference to certain preferred embodiments, the present invention may be variously modified and changed without departing from the spirit or the field of the present invention provided by the following utility model registration claims. It will be readily apparent to one of ordinary skill in the art that it can be used.
