본 발명은 자동차의 알루미늄 충격흡수빔에 관한 것으로, 특히 알루미늄 충격흡수빔의 전면에 주름판이 보강되어 구조적인 강성을 증대시켜 자동차의 충돌시에 탑승자 당을 보다 안전하게 보호할 수 있도록 된 자동차의 알루미늄 충격흡수빔의 보강구조에 관한 것이다.The present invention relates to an aluminum shock absorbing beam of an automobile, and in particular, an aluminum shock of an automobile which is capable of protecting the per-rider more safely in the event of a collision by increasing the structural rigidity by reinforcing a corrugated plate on the front surface of the aluminum shock absorbing beam. It relates to a reinforcing structure of an absorption beam.

일반적으로 자동차에는 주행중에 충돌시에 탑승자를 보다 안전하게 보호하기 위해 범퍼가 차체의 전후방에 장착되어 있는 바, 이 범퍼는 제일 바깥쪽에 장착되어 외관미를 향상시키는 페시아와, 이 페시아의 이면에 결합되어 자동차가 충돌되거나 추돌될 경우에 충격에너지를 1차적으로 흡수하는 발포고무와 같은 재질로 된 충격흡수재및, 이 충격흡수재의 이면에 결합되어 범퍼의 구조적인 강성을 증대시킴과 더불어 충격을 2차적으로 흡수하기 위해 범퍼스테이를 개재하여 차체와 체결되는 충격흡수빔을 갖춘 구조로 되어 있다.In general, in order to protect the occupants more safely in the event of a crash while driving, bumpers are mounted at the front and rear of the body, and the bumper is mounted on the outermost side to improve appearance and is coupled to the back of the fascia. Shock absorbers made of a material such as foam rubber that absorbs shock energy primarily in the event of a collision or collision with the vehicle, coupled with the back of the shock absorber to increase the structural rigidity of the bumper, It has a structure with a shock absorbing beam that is fastened to the vehicle body via a bumper stay for absorption.

여기서 상기 충격흡구빔은 대개가 스틸재질로 만들어져 범퍼의 전체적인 강성을 증대시키고 충격에너지를 일부 흡수하면서 차체로 분산시키는 역할을 하는 것인 바, 이 충격흡수빔은 스틸재질로 만들어지기 때문에 차체의 중량을 증대시키게 되므로, 중량이 가벼우면서도 충격을 적절히 흡수할 수 있는 알루미늄재질로 된 충격흡수빔이 개발되어 오고 있다.Here, the shock absorbing beam is mainly made of steel material to increase the overall stiffness of the bumper and serves to disperse the impact energy to the vehicle body while absorbing some of the impact energy. In order to increase the weight, an impact absorption beam made of aluminum, which is light in weight and capable of absorbing shock, has been developed.

즉 제2도에 도시된 것과 같이 종래의 알루미늄 충격흡수빔(11)은 직사각 육면체 형상을 이루고서 자동차의 폭방향을 따라 길게 연장되면서 내부에는 비어 있는 다수개의 채널이 형성됨과 더불어 양쪽 모서리 부위는 차체의 전방 및 후방으로 만곡되게 형성된 구조로 되어 있다.That is, as shown in FIG. 2, the conventional aluminum shock absorbing beam 11 forms a rectangular hexahedron shape and extends along the width direction of the vehicle, and a plurality of empty channels are formed therein, and both corner portions are formed in the vehicle body. It has a structure formed to be curved forward and backward.

그런데 상기와 같이 종래의 알루미늄 충격흡수빔(11)은 스틸재질의 충격흡수빔보다 중량이 가벼운 잇점이 있기는 하지만, 강도면에서는 스틸재질의 충격흡수빔보다 약하기 때문에 자동차의 충돌시에 충격을 견디어내기에는 미흡하다고 하는 결점이 있었다.As described above, although the conventional aluminum shock absorbing beam 11 has advantages in lighter weight than the steel shock absorbing beam, it is weaker than the steel shock absorbing beam in terms of strength, so it can withstand the impact during the collision of the vehicle. There was a flaw in the bet.

이에 본 발명은 상기한 결점을 해소하기 위해 안출된 것으로, 알루미늄재질로 만들어지는 충격흡수빔의 구조적인 강성을 증대시켜 중량이 가벼우면서도 자동차의 충돌시에 적절히 견디어낼 수 있도록 된 자동차의 알루미늄 충격흡수빔 보강구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and by increasing the structural rigidity of the shock absorbing beam made of aluminum material, the weight of the aluminum shock absorber of the car can be appropriately endured in the event of a car collision. The purpose is to provide a beam reinforcement structure.

상기한 바의 목적을 달성하기 위한 본 발명은, 직사각 육면체 형상을 하고서 자동차의 폭방향을 따라 길게 연장되면서 내부에는 비어 있는 다수개의 채널이 형성됨과 더불어 양쪽 모서리 부위는 차체의 전방 및 후방으로 만곡되게 형성된 자동차의 알루미늄 충격흡수빔에 있어서, 페시아의 이면과 결합되는 충격흡수빔의 전면에 다수의 요철로 이루어지는 알루미늄재질의 주름판이 일체로 부착되어 보강된 구조로 되어 있다.In order to achieve the above object, the present invention has a rectangular hexahedron shape and extends along the width direction of the vehicle, and a plurality of empty channels are formed therein, and both corner portions are curved toward the front and rear of the vehicle body. In the formed aluminum shock absorbing beam of the automobile, the aluminum corrugated plate made of a plurality of irregularities is integrally attached to the front of the shock absorbing beam coupled to the back surface of the fascia to be reinforced.

이에 따라 상기 주름판에 의해 충격흡수빔의 강성이 보강됨과 더불어 자동차의 충돌시에 페시아를 통해 전달되어 오는 충격을 상기 주름판의 요철부가 펴지면서 적절히 흡수하게 된다.Accordingly, the rigidity of the shock absorbing beam is reinforced by the corrugated plate, and the shocks transmitted through the fascia during the collision of the vehicle are appropriately absorbed while the uneven portion of the corrugated plate is unfolded.

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

제1도는 본 발명에 따른 자동차의 알루미늄 충격흡수빔의 개략적인 사시도인 바, 즉 알루미늄 충격흡수빔(1)이 직사각 육면체 형상을 이루고서 자동차의 폭방향을 따라 길게 연장되면서 내부에는 비어 있는 다수개의 채널(1a)이 형성됨과 더불어 양쪽 모서리 부위는 차체의 전방 및 후방으로 만곡되게 절곡부(1b)가 형성된 구조로 되어 있다.FIG. 1 is a schematic perspective view of an aluminum shock absorbing beam of a vehicle according to the present invention, that is, the aluminum shock absorbing beam 1 forms a rectangular hexahedron shape and extends along the width direction of the car, and thus is empty. In addition to the formation of the channel 1a, both corner portions have a structure in which the bent portion 1b is formed to be bent toward the front and the rear of the vehicle body.

그리고 페시아(도시되지 않음)의 이면과 결합되는 충격흡수빔(1)의 전면에 다수의 요철로 이루어지는 알루미늄재질의 주름판(2)이 일체로 부착되어 보강된 구조로 되어 있다.In addition, an aluminum corrugated plate 2 made of a plurality of irregularities is integrally attached to the front surface of the shock absorbing beam 1 coupled to the back surface of the fascia (not shown) and is reinforced.

이에 따라 상기 주름판(2)에 의해 알루미늄 충격흡수빔(1)의 구조적인 강성이 보강되게 되고, 또 자동차의 충돌시에 페시아를 통해 충격흡수빔쪽으로 전달되어 오는 충격은 먼저 상기 주름판(2)에 의해 일부가 흡수되어 상대적으로 적은 충격이 충격흡수빔에 전달되게 되는 데, 즉 상기 주름판(2)의 요철부가 충격에 의해 펴지면서 적절히 흡수함과 동시에 충격에너지를 충격흡수빔의 길이방향을 따라 좌우 양측으로 분산시키게 되므로, 알루미늄재질의 충격흡수빔이 가지는 강성의 취약성을 보완해주게 된다.Accordingly, the structural rigidity of the aluminum shock absorbing beam 1 is reinforced by the corrugated plate 2, and the impact transmitted to the shock absorbing beam through the fascia at the time of the collision of the vehicle is the first corrugated plate 2. By absorbing a portion of the shock absorber is relatively small impact is transmitted to the shock absorbing beam, that is, the uneven portion of the corrugated plate (2) is unfolded by the impact, while absorbing the appropriate energy at the same time in the longitudinal direction of the shock absorbing beam It is distributed along the left and right sides, thereby supplementing the weakness of the rigidity of the shock absorbing beam made of aluminum.

이상 설명한 바와 같이 본 발명에 따른 자동차의 알루미늄 충격흡수빔 보강구조에 의하면, 다수의 요철로 이루어진 보강판이 알루미늄 충격흡수빔에 부착되어, 자동차의 충돌시에 페시아를 통해 전달되어 오는 충격의 일부를 흡수하면서 충격흡수빔의 길이방향을 따라 분산시켜 충격집중을 방지하게 되어, 알루미늄재질의 충격흡수빔에서 미흡한 강성을 적절히 보완해서 중량이 가벼우면서도 자동차의 충돌시에 탑승자 등을 적절히 보호할 수 있는 효과가 있다.As described above, according to the aluminum shock absorbing beam reinforcing structure of the vehicle according to the present invention, a reinforcing plate made of a plurality of unevenness is attached to the aluminum shock absorbing beam to absorb a part of the shock transmitted through the fascia at the time of the collision of the car. In addition, the impact absorption beam is dispersed along the longitudinal direction of the shock absorbing beam to prevent impact concentration. The insufficient rigidity of the shock absorbing beam made of aluminum material is appropriately compensated for light weight and adequately protects the occupants in the event of a collision. have.
