본 발명은 자동차의 범퍼에 관한 것으로, 특히 범퍼페시아와 차체에 체결되는 충격흡수장치를 갖추고서 구조가 간단하면서 자동차의 충돌시에 충격을 적절히 흡수해서 탑승자 등을 보다 안전하게 보호할 수 있도록 된 자동차의 범퍼구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper of an automobile, and more particularly, to a bumper fascia and a shock absorbing device fastened to a vehicle body. It relates to a bumper structure.

일반적으로 차량에는 충돌시에 그 충격을 흡수하여 탑승자 등을 보호하기 위해 차체의 전방 및 후방에 범퍼가 장착되어 있는 바, 이와 같은 종래의 범퍼는 제2도에 도시된 것과 같이, 범퍼의 외관미를 향상시키기 위한 페시아(11)와, 이 페시아(11)의 이면에 부착되어 충격을 1차적으로 흡수하는 발포고무와 같은 충격흡수재(12)를 갖춘 구조로 되어 있다.Generally, bumpers are mounted on the front and rear of the vehicle body in order to absorb the shock during a collision and protect the occupants. Such a conventional bumper has the appearance beauty of the bumper as shown in FIG. And a shock absorbing material 12 such as foam rubber which is attached to the back surface of the fascia 11 and primarily absorbs the impact.

그리고 상기한 충격흡수재(12) 만으로는 차량 충돌시에 탑승자 등을 보다 효과적으로 보호하기가 미흡하기 때문에 대개는 스틸재질로 된 충격흡수빔(13)이 상기 충격흡수재(12)의 이면에 결합되고, 이 충격흡수빔(13)은 범퍼스테이(14)를 매개로 차체(15)에 보울트 체결되어 범퍼를 전체적으로 지지하도록 되어 있다.In addition, since the shock absorber 12 alone is insufficient to protect the occupants and the like more effectively during a vehicle crash, a shock absorber beam 13 made of steel is generally coupled to the rear surface of the shock absorber 12. The shock absorbing beam 13 is bolted to the vehicle body 15 via the bumper stay 14 to support the bumper as a whole.

상기한 종래의 범퍼는 자동차의 충돌이나 추돌시에 먼저 충격흡수재(12)가 충격을 1차적으로 흡수하고, 여분의 충격을 충격흡수빔(13)에 전달되어 충격흡수빔(13)이 충격을 적절히 흡수함과 동시에 차체(15)로 분산시켜 탑승자 쪽으로 가능한 한 충격이 적게 전달되도록 하여 탑승자 등을 보호하고 있다.In the conventional bumper, the shock absorber 12 first absorbs the shock at the time of collision or collision of the vehicle, and the extra shock is transmitted to the shock absorbing beam 13 so that the shock absorbing beam 13 receives the shock. It absorbs appropriately and at the same time is distributed to the vehicle body 15 so that the impact is transmitted to the occupant as little as possible to protect the occupant.

그런데 상기와 같은 종래의 범퍼는 충격흡수장치로서 발포고무와 같은 충격흡수재(12)와 스틸이나 알루미늄재질로 된 충격흡수빔이 사용되고, 또 상기 충격흡수빔을 차체에 체결시키기 위한 스테이를 사용하여 구조가 복잡할 뿐만 아니라 부품수가 많아지고 조립공정이 증가되어 자동차의 제조단가를 상승시킨다고 하는 결점이 있었다.However, the conventional bumper as described above uses a shock absorbing material 12 such as foam rubber and a shock absorbing beam made of steel or aluminum as a shock absorbing device, and uses a stay for fastening the shock absorbing beam to the vehicle body. In addition to the complexity, the number of parts is increased and the assembly process is increased, which increases the manufacturing cost of the automobile.

이에 본 발명은 상기한 결점을 해소하기 위해 안출된 것으로, 구조가 간단하면서도 자동차의 충돌이나 추돌시에 충격을 적절히 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, and the object of the present invention is to provide a bumper structure of a vehicle which is simple in structure and can absorb shocks appropriately in case of a collision or collision of a vehicle to protect the occupants more safely. There is this.

상기한 바의 목적을 달성하기 위한 본 발명은, 범퍼의 외관미를 향상시키기 위해 제일 외측에 부착되는 페시아와, 차체에 U자형상의 클립으로 체결되는 베이스 판스프링과, 이 베이스 판스프링위에 소정곡률로 만곡되어 겹쳐지는 제1판스프링, 이 제1판스프링에 소정곡률로 만곡되게 형성되면서 서로 인접해서 부착된 2개의 제2판스프링 및, 이 제2판스프링사이에 걸쳐지면서 소정곡률로 만곡되게 형성된 제3판스프링을 갖춘 구조로 되어 있다.The present invention for achieving the above object is a fascia attached to the outermost in order to improve the appearance of the bumper, a base plate spring fastened to the vehicle body with a U-shaped clip, and a predetermined curvature on the base plate spring A first plate spring that is curved and overlaps with each other, two second plate springs which are formed to be bent at a predetermined curvature on the first plate spring, and are attached adjacent to each other, and are bent at a predetermined curvature while being spanned between the second plate springs. It has a structure with the formed third leaf spring.

이에 따라 상기와 같이 베이스 판스프링과 만곡되게 형성된 다수개의 판스프링이 중첩되어 형성된 겹판스프링이 자동차의 충돌이나 혹은 추돌시에 충격흡수재와 충격흡수빔의 역할을 동시에 하여 탑승자 등을 보다 안전하게 보호할 수 있게 된다.Accordingly, the leaf spring formed by overlapping a plurality of leaf springs formed to be curved with the base leaf spring as described above can act as a shock absorber and a shock absorbing beam at the same time as a collision or collision of a vehicle, thereby protecting the occupants and the like more safely. Will be.

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 범퍼의 분리사시도인 바, 즉 범퍼의 외관미를 향상시키기 위해 제일 외측에 부착되는 페시아(1)와, 이 페시아(1)의 이면에 겹판스프링(2)이 배열되면서 이 겹판스프링(2)은 차체(3)의 전면에 부착된 장착브라켓(4)에 U자형상의 클립(5)로 체결되는 구조로 되어 있다.1 is an exploded perspective view of the bumper according to the present invention, that is, the facia (1) attached to the outermost to improve the appearance of the bumper, and the leaf spring (2) is arranged on the rear surface of the fascia (1) The leaf spring 2 is structured to be fastened by a U-shaped clip 5 to a mounting bracket 4 attached to the front surface of the vehicle body 3.

여기서 상기 겹판스프링(2)은 차체(3)에 U자형상의 클립(5)으로 체결되는 베이스 판스프링(2a)과, 이 베이스 판스프링(2a)위에 소정곡률로 만곡되어 겹쳐지는 제1판스프링(2b), 이 제1판스프링(2b)에 소정곡률로 만곡되게 형성되면서 서로 인접해서 부착된 2개의 제1판스프링(2b) 및, 이 제2판스프링(2c)사이에 걸쳐지면서 소정곡률로 만곡되게 형성된 제3판스프링(2d)을 갖춘 구조로 되어 있다.Here, the leaf spring (2) is a base plate spring (2a) is fastened to the vehicle body 3 by the U-shaped clip (5), and the first leaf spring is bent over a predetermined curvature on the base plate spring (2a) (2b) a predetermined curvature is formed between the two first leaf springs 2b and the second leaf springs 2c adjoined to each other while being curved to the first leaf spring 2b with a predetermined curvature. The third plate spring 2d is formed to be curved.

이에 따라 상기 겹판스프링(5)이 충격흡수재와 충격흡수빔의 역할을 동시에 수행해서 자동차의 충돌시에 충격을 적절히 흡수하여 완화시킬 뿐만 아니라 차체쪽으로 분산시켜 탑승자 등을 안전하게 보호할 수 있게 된다.Accordingly, the leaf spring 5 simultaneously plays the role of the shock absorber and the shock absorbing beam to absorb and mitigate the shock appropriately during the collision of the vehicle, as well as to distribute to the vehicle body to protect the passengers and the like.

그러므로 종래에 비해 구조가 상대적으로 간단하고 범퍼스테이와 같은 부품이 필요없게 되어, 부품수를 절감시킬 수 있게 된다.Therefore, compared with the conventional structure, the structure is relatively simple and there is no need for parts such as bumper stays, thereby reducing the number of parts.

이상 설명한 바와 같이 본 발명에 따른 자동차의 범퍼구조에 의하면, 구조가 간단하면서도 자동차의 충돌이나 추돌시에 충격을 적절히 흡수해서 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 structure is simple, but the impact can be appropriately absorbed in the event of a collision or collision of the vehicle, thereby protecting the occupants and the like more safely.
