본 발명은 자동차의 범퍼에 관한 것으로, 특히 자동차가 가로수나 가로등과 같이 폭이 좁은 물체에 정면으로 충돌하여 범퍼의 중앙부위에 집중적으로 충격이 가해질 때에 이를 적절히 흡수해서 탑승자 등을 보다 안전하게 보호할 수 있도록 자동차의 범퍼구조에 관한 것이다.The present invention relates to a bumper of an automobile, and in particular, when the automobile collides in front of a narrow object such as a roadside street or a streetlight and is intensively impacted at the center portion of the bumper, it can be properly absorbed to protect the occupants and the like. So that the bumper structure of the car.

일반적으로 자동차에는 충돌시에 그 충격을 흡수하여 탑승자 등을 보호하기 위해 차체의 전방 및 후방에 범퍼가 장착되어 있는 바, 이와 같은 종래의 범퍼는 제2도에 도시된 것과 같이 자동차의 충돌시에 충격에너지를 효과적으로 흡수할 수 있도록 발포고무와 같은 충격흡수재(1)의 전면쪽에 페시아(2)가 끼워져 결합되는 구조로 되어 있다.In general, bumpers are mounted on the front and rear of the vehicle body to absorb shocks and protect occupants, etc. in the event of a collision. Such conventional bumpers are used in the event of a collision of a vehicle as shown in FIG. In order to absorb shock energy effectively, the fascia 2 is fitted to the front side of the shock absorbing material 1 such as foam rubber.

그리고 상기한 충격흡수재(1)만으로는 자동차 충돌시에 탑승자 등을 보다 효과적으로 보호하기가 미흡하기 때문에 대개는 스틸재질로 된 충격흡수빔(3)이 충격흡수재(2)의 이면에 결합되어, 범퍼의 충돌강성을 보완하도록 되어 있다.In addition, since the shock absorber 1 alone is insufficient to protect the occupants and the like more effectively during an automobile crash, the shock absorber 3 made of steel is generally coupled to the rear surface of the shock absorber 2. It is designed to compensate for collision stiffness.

여기서 상기 충격흡수재(1)와 충격흡수빔(3)은 자동차의 폭방향으로 전체폭으로 걸쳐 균일하게 연장되도록 설치되어 있기 때문에 자동차의 폭방향으로는 거의 일정한 충격에너지 흡수능력을 갖게 되어, 자동차가 범퍼의 어떠한 방향으로 충돌되거나 추돌되더라도 거의 균일한 양으로 충격에너지를 흡수할 수 있게 된다.Here, since the shock absorber 1 and the shock absorbing beam 3 are installed to extend uniformly over the entire width in the width direction of the vehicle, the shock absorber 1 and the shock absorbing beam 3 have a substantially constant impact energy absorption capacity in the width direction of the vehicle. Any impact or collision in any direction of the bumper can absorb the impact energy in an almost uniform amount.

그런데 자동차는 주행중에 대부분은 정면으로 충돌할 가능성이 높고, 이에 따라 범퍼에 가해지는 충격량도 범퍼의 중앙부위에 집중적으로 가해지는 경우가 많은 데, 특히 예컨대 자동차가 가로수나 가로등과 같이 폭이 좁은 물체와 정면으로 충돌될 경우에는 범퍼의 중앙부위에 충격이 집중되어, 범퍼와 충격흡수빔이 과도하게 휘어질 뿐만 아니라 그 충격에너지를 효과적으로 흡수하기가 미흡하다고 하는 결점이 있었다.However, most of the cars are likely to collide with each other while driving, and thus the amount of impact applied to the bumper is often concentrated in the center of the bumper. In particular, the car is a narrow object such as a street tree or a street lamp. In the case of colliding with the front face, the impact is concentrated at the center of the bumper, so that the bumper and the shock absorbing beam not only bend excessively, but also insufficiently absorb the impact energy.

이에 본 발명은 상기한 종래 결점을 해소하기 위해 안출된 것으로, 자동차가 가로수나 가로등과 같은 폭이 좁은 물체에 충돌되거나 혹은 추돌될 경우에 특히 중앙부위에 집중되는 충격에너지를 효과적으로 흡수해서 탑승자 등을 보다 안전하게 보호할 수 있도록 된 자동차의 범퍼구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-described drawbacks, particularly when the car collides with or collides with a narrow object such as a roadside street or a street light, it absorbs the impact energy concentrated in the center part effectively and thus occupies a passenger. The object is to provide a bumper structure of a vehicle that can be more securely protected.

상기한 바의 목적을 달성하기 위한 본 발명은, 자동차의 충돌시에 충격을 1차적으로 흡수하는 충격흡수재에 페시아가 덮어씌워져 스크류를 매개로 체결되고, 상기 충격흡수재보다 상재적으로 강성이 높은 스틸재질로 된 충격흡수빔이 충격흡수재에 끼워져 결합되는 한편, 상기 충격흡수빔의 길이방향을 따른 중앙부위에 완충장치가 충격흡수재내부로 돌출되게 장착된 구조로 되어 있다.In order to achieve the above object, the present invention is to cover the shock absorber that absorbs the impact primarily at the time of impact of the vehicle is fastened through the screw through the screw, the steel is substantially higher rigidity than the shock absorber The shock absorbing beam made of a material is coupled to the shock absorbing material, while the shock absorbing device is mounted to protrude into the shock absorbing material at a central portion in the longitudinal direction of the shock absorbing beam.

여기서 상기 완충장치는 알루미늄관이 여러 겹으로 접혀진 판스프링으로 이루어진다.Here, the shock absorber is composed of a leaf spring in which the aluminum tube is folded in several layers.

이에 따라, 범퍼의 특히 중앙부위가 예컨대 가로수나 혹은 가로등에 충돌될 경우에 상기 충격흡수재가 충격을 1차적으로 흡수함은 물론이고 이와 동시에 상기 판스프링도 충격을 보다 효과적으로 흡수하게 되어, 자동차의 충돌이나 추돌시에 범퍼와 충격흡수빔이 굽혀지는 정도를 줄일 수 있을 뿐만 아니라 탑승자 등을 보다 안전하게 보호할 수 있게 된다.Accordingly, in the case where the central part of the bumper collides with, for example, a roadside street or a street light, the shock absorber primarily absorbs the shock, and at the same time, the leaf spring also absorbs the shock more effectively. In addition, the bumper and the impact absorbing beam can be reduced in the event of a collision, as well as to protect the occupants more safely.

이하 본 발명은 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 범퍼의 분리사시도인 바, 즉 충돌이나 추돌시에 충격을 1차적으로 흡수하는 충격흡수재(1)에 페시아(2)가 덮어씌워져 스크류를 매개로 체결되고, 상기 충격흡수재(1)보다 상대적으로 강성이 높은 스틸재질로 된 충격흡수빔(3)이 충격흡수재(1)에 기워져 결합되는 한편, 상기 충격흡수재(1)의 길이방향을 따른 중앙부위에 4각형상의 끼움홈(1a)이 형성되면서 이 끼움홈(1a)속에 완충장치가 수납된 구조로 되어 있다.1 is an exploded perspective view of the bumper according to the present invention, that is, the fascia (2) is covered with a shock absorber (1) that absorbs the shock primarily during a collision or collision, and is fastened through a screw. A shock absorbing beam (3) made of steel material having a relatively higher rigidity than (1) is coupled to the shock absorbing member (1) while being fitted in a quadrangular shape at the central portion along the longitudinal direction of the shock absorbing member (1). As the groove 1a is formed, the shock absorber is accommodated in the fitting groove 1a.

여기서 상기 완충장치는 알루미늄판이 여러 겹으로 접혀진 판스프링(4)의 하부가 충격흡수빔(3)에 리벳으로 체결된 구조로 되어 있다.Here, the shock absorber has a structure in which a lower portion of the leaf spring 4 in which the aluminum plate is folded in multiple layers is fastened to the shock absorbing beam 3 by rivets.

따라서 자동차가 예컨대 가로수나 가로등과 같이 폭이 좁은 물체와 정면으로 충돌되거나 추돌될 경우에 상기 충격흡수재(1)가 충격을 1차적으로 흡수함과 동시에 상기 판스프링(4)이 충격을 추가적으로 흡수해서 범퍼와 충격흡수빔이 휘어지는 정도를 줄일수 있고, 또 탑승자 등을 보다 안전하게 안전하게 보호할 수 있게 된다.Therefore, when the vehicle collides or collides with a narrow object such as a street or street light in front of the vehicle, the shock absorber 1 absorbs the shock and at the same time, the leaf spring 4 additionally absorbs the impact. It is possible to reduce the degree of warpage of the bumper and the shock absorbing beam, and to protect the occupants more safely and safely.

이상 설명한 바와 같이 본 발명에 따른 자동차의 범퍼구조에 의하면, 범퍼의 중앙부위에 장착된 완충장치에 의해 자동차의 정면충돌시나 추돌시에 충격에너지를 효과적으로 흡수함으로써 탑승자 등을 보다 안전하게 보호할 수 있는 효과가 있다.As described above, according to the bumper structure of the vehicle according to the present invention, the shock absorber mounted on the center portion of the bumper effectively absorbs the impact energy during the frontal collision or the collision of the vehicle, thereby effectively protecting the occupants and the like. There is.
