자동차의 범퍼조립체Bumper Assembly of Car

본 고안은 자동차의 범퍼조립체에 관한 것으로서, 더욱 상세하게는 자동차의 전면 또는 후면에 제공되어 차체를 보호하는 자동차의 범퍼조립체의 에너지업소버의 개선에 관한 것이다.The present invention relates to a bumper assembly of an automobile, and more particularly, to an improvement in an energy absorber of a bumper assembly of a vehicle provided on a front or rear side of an automobile to protect a vehicle body.

주지된 바와 같이, 자동차의 전면 및 후면에는 차체를 보호하기 위한 범퍼가 설치되어 있다. 이러한 범퍼는 규격화된 강도를 보유하여야 하며, 이런 강도를 가지는 범퍼는 차량의 저속충돌시에는 파손되지 않고 완충력에 의해 차체를 보호하게 되며, 고속충돌시에는 완충과 동시에 파손되어 엔진실로 충격이 전달되지 않도록 구성되어야 한다.As is well known, bumpers are provided on the front and rear of the vehicle to protect the vehicle body. These bumpers must have standardized strength, and bumpers with these strengths are not damaged during low speed collisions of the vehicle and are protected by the cushioning force. It should be configured to

따라서, 범퍼는 커버의 내측에 완충력을 지닌 에너지업소버가 제공되고 동시에 강도를 보유하는 임팩트빔이 제공되어 있다. 범퍼는 차체의 양측에 길이방향으로 배열되어 있는 이른바 롱지튜디널이라 불리는 종방향프레임상에 체결된다.Accordingly, the bumper is provided with an energy absorber having a buffering force inside the cover and at the same time an impact beam having strength. The bumper is fastened on a longitudinal frame called the long ground, which is arranged longitudinally on both sides of the vehicle body.

지금부터는 도 1을 참고하여 종래에 따른 자동차의 범퍼조립체의 구성 및 결합관계를 설명한다.A configuration and a coupling relationship of a bumper assembly of a vehicle according to the related art will now be described with reference to FIG. 1.

도 1에 따르면, 커버(20)의 내측에는 발포수지로 이루어진 에너지업소버(26)가 제공되고, 이 에너지업버(26)의 내측에는 임팩트빔(22)이 밀착되며, 이 임팩트빔(22)은 체결편(24)에 의해서 커버(20)와 나사결합되어 있다. 에너지업소버(26)는 임팩트빔(22)과 커버(20)가 체결되면서 에너지업소버(26)의 전면과 후면을 가압하기 때문에 커버(20)의 내측에 지지된다. 임팩트빔(22)의 후단에는 범퍼스테이(28)가 고정되어 있으며, 범퍼스테이(28)는 후방으로 연장되어 차체(10)의 양측에 길이방향으로 배열되는 종방향프레임(30)에 볼트(40)에 의해서 고정되어 있다.According to FIG. 1, an energy absorber 26 made of foamed resin is provided inside the cover 20, and an impact beam 22 is in close contact with the inside of the energy absorber 26. It is screwed with the cover 20 by the fastening piece 24. As shown in FIG. The energy absorber 26 is supported inside the cover 20 because the impact beam 22 and the cover 20 are fastened to press the front and rear surfaces of the energy absorber 26. A bumper stay 28 is fixed to the rear end of the impact beam 22, and the bumper stay 28 extends rearward and is bolted to a longitudinal frame 30 arranged longitudinally on both sides of the vehicle body 10. It is fixed by).

이와 같은 구성으로 이루어진 자동차의 범퍼조립체는 이미 설명한 바와 같이 저속으로 충돌하였을 때에는 에너지업소버(26)의 완충작용과 임팩트빔(22)의 강성에 의해서 충격이 흡수완충되고, 고속으로 충돌하였을 때에는 에너지업소버(26)가 파손됨과 동시에 임팩트빔(22)이 꺽여지면서 전달되는 충격을 흡수하여 엔진룸을 보호하게 되는 것이다.As described above, the bumper assembly of an automobile having such a configuration absorbs and absorbs the shock due to the buffering action of the energy absorber 26 and the rigidity of the impact beam 22 when colliding at a low speed, and the energy absorber when colliding at a high speed. At the same time as the 26 is damaged, the impact beam 22 is bent to absorb the shock transmitted to protect the engine room.

그러나, 이와 같은 기존의 자동차의 범퍼조립체에 의하면 자동차가 충돌하였을 때에 충격을 최초로 흡수하게 되는 에너지업소버(26)는 전체가 압축된 하나의 재질로 형성되어 있기 때문에 충격이 가해졌을 때 재질고유의 완충력에 의해서만 충격을 흡수하게 된다. 그러므로, 종래의 자동차의 범퍼조립체는 충격흡수력이 적어 충격대응에 미흡하다는 문제점이 있었다.However, according to the conventional bumper assembly of the automobile, the energy absorber 26, which absorbs the impact for the first time when the vehicle collides, is formed of a single compressed material, and thus has a unique buffering force when the impact is applied. The shock is absorbed only by. Therefore, the bumper assembly of the related art vehicle has a problem in that the shock absorbing power is low and the shock response is insufficient.

이에 본 고안은 상기와 같은 점을 감안하여 안출된 것으로서, 그 목적은 충격흡수력이 우수한 에너지업소버를 구비한 자동차의 범퍼조립체를 제공함에 있다.The present invention has been made in view of the above, the object is to provide a bumper assembly of a vehicle having an energy absorber excellent in shock absorption.

이와 같은 목적을 달성하기 위해서 본 고안에 따른 자동차의 범퍼조립체는 커버와 임팩트빔의 사이에 에너지업소버가 개재되어 있는 자동차의 범퍼조립체에 있어서, 에너지업소버의 내부에는 에너지업소버의 길이방향을 따라 적당한 간격을 두고 수직방향으로 길게 형성된 복수의 밀폐공간이 형성되고, 에너지업소버의 전면과 후면에는 내부에 밀폐공간이 형성된 복수개의 완충돌기가 에너지업소버와 일체로 형성된 것을 특징으로 한다.In order to achieve the above object, the bumper assembly of an automobile according to the present invention is a bumper assembly of an automobile in which an energy absorber is interposed between a cover and an impact beam. An interior of the energy absorber has a proper distance along the longitudinal direction of the energy absorber. A plurality of enclosed spaces formed in the vertical direction are formed, and a plurality of shock absorbing protrusions formed in the enclosed spaces are formed integrally with the energy absorber on the front and the rear of the energy absorber.

이하, 본 고안에 따른 자동차의 범퍼조립체의 바람직한 실시예를 첨부도면에 의거하여 상세하게 설명한다(종래와 같은 구성요소에 대해서는 동일한 부호를 사용하여 설명한다).Hereinafter, a preferred embodiment of a bumper assembly of a vehicle according to the present invention will be described in detail with reference to the accompanying drawings (the same components will be described with the same reference numerals).

도 2에는 본 고안에 따른 자동차의 범퍼조립체의 구성을 보인 측단면도가 도시되어 있다. 이에 따르면, 본 고안에 따른 자동차의 범퍼조립체는 커버(20)와 임팩트빔(22)이 체결편(24)에 의해서 나사 결합되어 있다.Figure 2 is a side cross-sectional view showing the configuration of the bumper assembly of the vehicle according to the present invention. According to this, in the bumper assembly of the vehicle according to the present invention, the cover 20 and the impact beam 22 are screwed by the fastening piece 24.

커버(20)와 임팩트빔(22) 사이에는 발포수지로 이루어진 에너지업소버(26)가 위치하며, 이 에너지업소버(26)는 임팩트빔(22)과 커버(20)가 체결되면서 에너지업소버(26)의 전면과 후면을 가압하기 때문에 커버(20)의 내측에 지지된다. 또한, 완충역활을 할 수 있도록 에너지업소버(26)의 내부는 공기가 충전되는 밀폐공간(26a)이 형성되어 있다. 이 밀폐공간(26a)의 형상은 수직방향으로 길게 형성되어 있으며, 밀폐공간(26a)은 에너지업소버(26)를 정면에서 보았을 때에 길이방향을 따라 적당한 간격을 두고 다수개가 형성되어 있다. 또한, 에너지업소버(26)의 전면과 후면에는 공기가 충전되는 밀폐공간(27a)이 형성된 완충돌기(27)들이 에너지업소버(26)와 일체로 형성되어 있다.Between the cover 20 and the impact beam 22 is an energy absorber 26 made of a foamed resin, the energy absorber 26 is the energy absorber 26 as the impact beam 22 and the cover 20 are fastened It is supported on the inside of the cover 20 because it presses the front and back. In addition, a sealed space 26a is formed inside the energy absorber 26 to fill the air so as to act as a buffer. The shape of the sealed space 26a is formed long in the vertical direction, and a plurality of the sealed spaces 26a are formed at appropriate intervals along the longitudinal direction when the energy absorber 26 is viewed from the front. In addition, the front and rear of the energy absorber 26, the buffer protrusions 27 are formed integrally with the energy absorber 26 is formed a sealed space (27a) is filled with air.

한편, 임팩트빔(22)의 후단에는 범퍼스테이(28)가 고정되어 있으며, 범퍼스테이(28)는 후방으로 연장되어 차체(10)의 양측에 길이방향으로 배열되는 종방향프레임(30)에 볼트(40)에 의해서 고정되어 있다.On the other hand, the bumper stay 28 is fixed to the rear end of the impact beam 22, the bumper stay 28 is extended to the rear bolts to the longitudinal frame 30 which is arranged in the longitudinal direction on both sides of the vehicle body (10) It is fixed by 40.

지금부터는, 이와 같은 구성으로 이루어진 본 고안에 따른 자동차의 범퍼조립체의 작용을 설명한다.Now, the operation of the bumper assembly of the vehicle according to the present invention having such a configuration will be described.

먼저, 자동차가 저속으로 충돌하였을 때에는 에너지업소버(26)의 완충작용과 임팩트빔(22)의 강도에 의해서 충격이 흡수완충된다. 이 때, 에너지업소버(26)의 밀폐공간(26a,27a)이 압축되면서 발생하는 완충력에 의해 일차적인 완충이 이루어지고, 에너지업소버(26)의 재질이 가지고 있는 재질고유의 완충력에 의해서 이차적인 완충이 이루어지므로 전체적인 충격흡수력은 증대되는 것이다.First, when the vehicle collides at a low speed, the shock is absorbed and buffered by the buffering action of the energy absorber 26 and the strength of the impact beam 22. At this time, the primary buffer is made by the buffer force generated while the sealed spaces 26a and 27a of the energy absorber 26 are compressed, and the secondary buffer is made by the material-specific buffer force of the material of the energy absorber 26. As a result, the overall shock absorbing power is increased.

한편, 자동차가 고속으로 충돌하였을 때에는 에너지업소버(26)가 파손됨과 동시에 임팩트빔(22)이 꺽여지면서 전달되는 충격을 흡수하여 엔진룸을 보호하게 된다. 이때 에너지업소버(26) 자체가 파손되면서 충격을 흡수하기도 하지만 이에 더해서 밀폐공간(26a,27a)이 터지면서 밀폐공간(27)내에 있는 공기들의 반발력에 의해서 충격흡수력은 증대되는 것이다.On the other hand, when the car collides at a high speed, the energy absorber 26 is damaged and the impact beam 22 is bent to absorb the shock transmitted to protect the engine room. At this time, the energy absorber 26 itself may be damaged while absorbing the shock, but in addition, the shock absorbing force is increased by the repulsive force of the air in the sealed space 27 as the sealed spaces 26a and 27a burst.

이상에서 설명한 바와 같이 본 고안에 따른 자동차의 범퍼조립체는 에너지업소버를 성형할 때에 에너지업소버의 내부와 외측에 밀폐공간을 형성하여 충돌시 에너지업소버의 재질고유의 완충력과 아울러 밀폐공간이 압축되면서 발생되는 완충력에 의해서 우수한 충격흡수력을 얻을 수 있는 효과를 갖게 되는 것이다.As described above, the bumper assembly of a vehicle according to the present invention forms a sealed space inside and outside of the energy absorber when the energy absorber is molded, and is generated by compressing the sealed space as well as the buffering capacity of the energy absorber. It is to have the effect of obtaining excellent shock absorption by the buffering force.
