(産業上の利用分野)
この発明は、衝突時の変形を規正する自動車のパン・ぐ
構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a panning structure for an automobile that regulates deformation during a collision.
(従来技術)
衝突時に作用する荷重を、ウレタン等の衝突エネルギ吸

5349号公報参照)。(Prior Art) Various configurations have been devised for automobile bumpers in which the load acting during a collision is absorbed by collision energy absorbing materials such as urethane (for example,
(See Publication No. 5349).

になる。However, such conventional bumpers have the following problems. That is, a collision energy absorbing material 2 such as urethane is brought into contact with the bumper and pan/J beam 1 of the conventional example shown in FIG. However, when a load E at the time of a collision is applied to this, the skin 3 along with the energy absorbing material 2 is deformed to protrude upward and downward as shown by the chain line. The upwardly protruding objects then come into contact with the vehicle body/channels or lamps 5 located at the top, damaging them and deteriorating their appearance.
(発明の目的)
この発明は、前記の問題点に対し、これを解消する自動
車のバンパ構造を提供するようにしたものである。(Object of the Invention) The present invention provides an automobile bumper structure that solves the above-mentioned problems.

造である。(Structure of the Invention) This invention provides a structure in which a collision energy absorbing material is brought into contact with the front surface of a pan/4' beam and is covered with a skin. While forming an inclined surface that displaces the material downward,
This is an automobile pan i9 structure in which a boss is provided on the inner surface of the skin to prevent displacement of the energy absorbing material in the vertical direction.
(実施例)
この発明の詳細を、第1図〜第3図に示す実施例につい
て説明すると、次の通りである。(Example) The details of the present invention will be explained with reference to the embodiment shown in FIGS. 1 to 3 as follows.
車体の前部または後部に取付げられるパンハ10は、閉
断面形状からなるパンツやビーム12の正面パネル13
に、ウレタン等の衝突エネルギ吸収材15を当接させ、
これらを弾性を有する表皮16で覆うとともに、表皮1
6をビーム12に固着して一体的に形成する。The panzer 10 attached to the front or rear of the vehicle body is a front panel 13 of the pant or beam 12 that has a closed cross-sectional shape.
A collision energy absorbing material 15 such as urethane is brought into contact with the
These are covered with an elastic epidermis 16, and the epidermis 1
6 is fixed to the beam 12 and formed integrally.
この構造において、衝突時に表皮16の正面に荷重Fが

13を、第2図に示すように、荷重Fの作用方向に対し
て傾斜させて形成する。そして衝突エネルギ吸収材15
も正面パネル13に当接するように傾斜させて形成する
。In this structure, a load F acts on the front of the skin 16 during a collision, deforming the skin 16 and the collision energy absorbing material 15. However, in this invention, the front panel 13 of the pants 4 beam 12 is , are formed to be inclined with respect to the direction of action of the load F. And collision energy absorbing material 15
It is also formed to be inclined so as to come into contact with the front panel 13.
また正面パネル13に当接する衝突エネルギ吸収材15
の下部を、第3図に示すように、たとえば波形18(高
さH)に形成して、変形しやすい形状にする。Also, the collision energy absorbing material 15 that comes into contact with the front panel 13
As shown in FIG. 3, the lower part is formed into a waveform 18 (height H), for example, to make it easily deformable.
さらに表皮16の内面に、第2図に示すように、はぼ水

移動が容易になる。Therefore, when a load F is applied to the skin 16 during a collision, the collision energy absorbing material 15 located inwardly comes into pressure contact with the front face/gunnel 13 of the slanted pants 4 beam 12, and at the same time, the slanted gunnel surface Move diagonally downward (direction D) along . Since the easily deformable corrugations 18 are formed in the lower part of the absorbent material 15, the absorbent material 15 can be easily moved downward.

することがない。In addition, since the boss nodule provided on the inner surface of the skin 16 is engaged with the absorbent material 15, the skin 16 moves together with the absorbent material 15,
Only the epidermis 16 will not be displaced in the vertical direction. In other words, since the absorbent material 15 moves diagonally downward when the collision load F acts on it, the skin 16 also displaces diagonally downward as shown by the chain line in FIG. There's nothing to do.

い。(Effects of the Invention) As described above, the present invention includes forming the front panel 13 of the bumper beam 12 at an angle, and attaching the collision energy absorbing material to the front panel 13 of the bumper beam 12.
5 are brought into contact with each other, and a detent is provided protruding from the outer skin 16 to engage with the absorbent material 15, so deformation in the event of a collision is restricted downward and deformation upward is prevented. Therefore, body panels or rungs located above the bumper
It will not come into contact with the product (and will not damage its appearance).

Therefore, as shown in FIG. 2, if the lower bottom part 24 of the bumper beam 12 is set below the stay 5 that attaches the bumper 10 to the vehicle body, a downward rotational moment M will act on the bumper 10 due to the above component force. Upward deformation of the epidermis 16 is reliably prevented.
