Description
본 고안은 자동차의 후방범퍼에 관한 것으로, 특히 자동차의 후방범퍼에 집중적으로 충격이 가해질 때에 이를 적절히 흡수해서 탑승자 등을 보다 안전하게 보호할 수 있도록 된 자동차의 후방범퍼 구조에 관한 것이다.The present invention relates to a rear bumper of a vehicle, and more particularly, to a rear bumper structure of a vehicle that is capable of appropriately absorbing it when the impact is intensively applied to the rear bumper of the vehicle to protect the occupants and the like.
일반적으로, 자동차에는 충돌시에 그 충격을 흡수하여 탑승자 등을 보호하기 위해 차체의 전방 및 후방에 범퍼가 장착되어 있는 바, 이와 같은 종래의 범퍼는 도 2에 도시된 것과 같이, 자동차의 충돌시에 충격에너지를 효과적으로 흡수할 수 있도록 발포고무와 같은 충격흡수재(110)의 전면쪽에 페시아(120)가 끼워져 결합되는 구조로 되어 있다.In general, bumpers are mounted on the front and rear of the vehicle body in order to absorb the shock during a collision to protect the occupants and the like. Such a conventional bumper is shown in FIG. In order to effectively absorb the impact energy to the structure of the Pescia 120 is fitted to the front side of the shock absorber 110, such as foam rubber.
그리고, 상기한 충격흡수재(110)만으로는 자동차 충돌시에 탑승자 등을 보다 효과적으로 보호하기가 미흡하기 때문에 대개는 스틸 재질로 된 충격흡수빔(100)이 충격흡수재(110)의 이면에 결합되어, 범퍼의 충돌강성을 보완하도록 되어 있다.In addition, since the shock absorber 110 alone is insufficient to protect the occupant and the like more effectively during an automobile crash, the shock absorber beam 100 made of steel is usually coupled to the rear surface of the shock absorber 110, thereby providing a bumper. The collision stiffness of the
여기서, 상기 충격흡수재(110)와 충격흡수빔(100)은 자동차의 폭 방향으로 전체 폭에 걸쳐 균일하게 연장되도록 설치되어 있기 때문에 자동차의 폭 방향으로는 거의 일정한 충격에너지 흡수 능력을 갖게 되어, 자동차가 범퍼의 어떠한 방향으로 충돌되거나 추돌되더라도 거의 균일한 양으로 충격에너지를 흡수할 수 있게 된다.Here, since the shock absorber 110 and the shock absorbing beam 100 are installed to extend uniformly over the entire width in the width direction of the vehicle, the shock absorber 110 and the impact absorbing beam 100 have a substantially constant impact energy absorption capability in the width direction of the vehicle. When the bumps collide or collide in any direction of the bumper, the impact energy can be absorbed in an almost uniform amount.
그런데 자동차는 주행 중에 대부분은 정면으로 충돌할 가능성이 높고, 이에 따라 범퍼에 가해지는 충격량도 범퍼의 중앙 부위에 집중적으로 가해지는 경우가 많은데, 특히 예컨대 각 부품들의 진동 및 타이어의 반복 하중에 의한 피로 현상이 발생되는 경우 상기 후방범퍼의 중앙 부위에 충격이 집중되어, 범퍼와 충격흡수빔이 과도하게 휘어질 뿐만 아니라 그 충격에너지를 효과적으로 흡수하기가 미흡하다고 하는 문제점이 있었다.However, most of the cars are likely to collide in the front while driving, and thus the amount of impact applied to the bumper is often concentrated in the center of the bumper. When the phenomenon occurs, the impact is concentrated in the center portion of the rear bumper, there is a problem that the bumper and the shock absorbing beam not only bend excessively, but also insufficient absorption of the impact energy effectively.
이에 본 고안은 상기한 종래 결점을 해소하기 위해 안출된 것으로, 자동차의 후방범퍼에 집중적으로 충격이 가해질 때에 이를 적절히 흡수해서 탑승자 등을 보다 안전하게 보호할 수 있도록 자동차의 후방범퍼 구조를 제공하는 데에 그 목적이 있다.Therefore, the present invention has been devised to solve the above-mentioned drawbacks, and when the concentrated impact is applied to the rear bumper of the car, it is appropriately absorbed to provide a rear bumper structure of the car so as to protect the occupants more safely. The purpose is.
상기한 바의 목적을 달성하기 위한 본 고안은, 자동차의 충돌시에 충격을 1차적으로 흡수하는 충격흡수재에 페시아가 덮어 씌워져 스크류를 매개로 체결되고, 상기 충격흡수재보다 상대적으로 강성이 높은 스틸 재질로 된 충격흡수빔이 충격흡수재에 끼워져 결합되는 한편, 상기 충격흡수빔의 길이 방향을 따른 중앙 부위에 완충장치가 충격흡수재 내부로 돌출되게 장착된 구조로 되어 있다.The present invention for achieving the object of the above is, the Pescia is covered with a shock absorber that absorbs the shock primarily in the collision of the vehicle is fastened via a screw, the steel material is relatively rigid than the shock absorber The shock absorbing beam is fitted to the shock absorbing material and coupled to the shock absorbing material, while the shock absorbing device is configured to protrude into the shock absorbing material at a central portion along the longitudinal direction of the shock absorbing beam.
이에 따라 범퍼의 특히 중앙 부위가 예컨대 가로수나 혹은 가로등에 충돌될 경우에 상기 충격흡수재가 충격을 1차적으로 흡수함은 물론이고, 상기 완충장치가 충격을 보다 효과적으로 흡수하게 되어, 자동차의 충돌이나 추돌시에 범퍼와 충격흡수빔이 굽혀지는 정도를 줄일 수 있고 탑승자 등을 보다 안전하게 보보할 수 있게 되는 것이다.Accordingly, the shock absorber primarily absorbs shock when the central part of the bumper collides with, for example, a roadside street or a street light, and the shock absorber absorbs the shock more effectively. When the bumper and shock absorbing beams are bent, the degree of bending can be reduced, and the occupants can be more securely secured.

이하, 본 고안을 첨부된 예시도면을 참조로 하여 일 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment will be described in detail with reference to the accompanying drawings of the present invention.
도 2는 본 고안에 따른 자동차의 후방범퍼에 완충장치가 삽입된 상태의 사시도 및 부분 단면도로서, 충돌이나 추돌시에 충격을 일차적으로 흡수하는 충격흡수재(10)에 페시아(20)가 덮어 씌워져 스크류를 매개로 체결되고, 상기 충격흡수재(10)보다 상대적으로 강성이 높은 스틸 재질로 된 충격흡수빔(30)이 충격흡수재(10)에 끼워져 결합되는 한편, 상기 충격흡수빔(30)의 길이 방향을 따라 충격을 이차로 흡수하여 주는 완충장치(40)가 부착 설치된 구조로 되어 있다.2 is a perspective view and a partial cross-sectional view of a state in which a shock absorber is inserted into a rear bumper of a vehicle according to the present invention, in which a fascia 20 is covered with a shock absorber 10 that primarily absorbs a shock during a collision or collision. And a shock absorbing beam 30 made of a steel material having a relatively higher rigidity than that of the shock absorbing material 10 is fitted to the shock absorbing material 10, and coupled to the shock absorbing material 10. Along with this, the shock absorber 40 that absorbs the secondary shock is attached to the structure.
여기서, 상기 완충장치(40)는 금속재질로 형성되면서 내부의 공간에 보강대가 일체로 사출된 보강 브래킷으로 이루어져 있고, 이 보강 브래킷의 하단에 형성된 플랜지부가 충격흡수빔(30)에 용접 등으로 고정 설치된 구조로 되어 있다.Here, the shock absorber 40 is made of a metal material made of a reinforcing bracket integrally injected into the interior space, the flange portion formed at the bottom of the reinforcing bracket is fixed to the shock absorbing beam 30 by welding or the like. It is installed structure.
따라서, 자동차가 예컨대 가로수나 가로등과 같이 폭이 좁은 물체와 정면으로 충돌되거나 추돌될 경우에 상기 충격흡수재(10)가 충격을 일차적으로 흡수함과 동시에 상기 완충장치(40)가 충격을 추가적으로 흡수해서 범퍼와 충격흡수빔이 휘어지는 정도를 줄일 수 있게 되고, 또 탑승자 등을 보다 안전하게 보호할 수 있게 된다.Therefore, when the vehicle collides or collides with a narrow object such as a street or a street lamp in front, the shock absorber 10 primarily absorbs the shock and at the same time the shock absorber 40 additionally absorbs the shock. It is possible to reduce the degree of warpage of the bumper and the shock absorbing beam, and to further protect the occupants.
이상 설명한 바와 같이 본 고안에 따른 자동차의 후방범퍼 구조에 의하면, 후방범퍼의 중앙 부위에 장착된 완충장치에 의해 자동차의 후면 충돌시나 추돌시에 충격에너지를 효과적으로 흡수함으로써 탑승자 등을 보다 안전하게 보호할 수 있는 효과가 있다.As described above, according to the rear bumper structure of the vehicle according to the present invention, the shock absorber mounted on the center portion of the rear bumper effectively protects the occupants and the like by absorbing the impact energy during the rear collision or the collision of the vehicle. It has an effect.
