본 고안은 차량의 범퍼 스테이에 관한 것으로서, 범퍼 스테이의 적소에 노치를 형성하여 충돌시 범퍼 스테이의 변형을 촉진하여 충돌에너지를 효과적으로 흡수할 수 있도록 한 것이다.The present invention relates to a bumper stay of a vehicle, and to form a notch in place of the bumper stay to promote the deformation of the bumper stay during collision to effectively absorb the collision energy.
범퍼는 자동차가 다른 자동차 또는 물체와 충돌하였을때, 탑승자의 안전과 차체손상 방지를 위해 차량의 전후단측에 설치하는 충격흡수장치이다.The bumper is a shock absorber installed at the front and rear ends of the vehicle to protect the occupant's safety and damage to the vehicle when the vehicle collides with another vehicle or an object.
종래의 범퍼 구조는 제1도에 도시한 바와 같이, 차량의 충격을 흡수 완화할 수 있는 에너지 압소버와(1), 상기 에너지 압소버(1)를 고정하며 범퍼 스테이(2)에 의해 프레임(3)에 지지되는 범퍼빔(4)으로 구성된다.In the conventional bumper structure, as shown in FIG. 1, an energy absorber (1) capable of absorbing and mitigating a shock of a vehicle, and the energy absorber (1) are fixed to each other by a bumper stay (2). It consists of the bumper beam 4 supported by 3).
상기 범퍼빔(4)은 상기 에너지 압소버(1)와 결합하는 외측 범퍼빔(4a)과 범퍼 스테이(2)와 결합하는 내측 범퍼빔(4b)을 용접하여 구성된다.The bumper beam 4 is constructed by welding an outer bumper beam 4a that is coupled to the energy absorber 1 and an inner bumper beam 4b that is coupled with the bumper stay 2.
미설명 부호 (5)는 차량의 외관을 향상시키기 위해 에너지 압소버를 감싼 훼시아이다.Reference numeral 5 denotes a fascia wrapped with an energy absorber to improve the appearance of the vehicle.
또한 제2도에 도시한 바와 같이, 범퍼 스테이(2)의 선단은 상기 내측 범퍼빔(4b)에 용접되고, 범퍼 스테이(2)의 후단부는 볼트구멍(6)을 형성하여 상기 프레임(3)에 볼팅된다.As shown in FIG. 2, the tip of the bumper stay 2 is welded to the inner bumper beam 4b, and the rear end of the bumper stay 2 forms a bolt hole 6 to form the frame 3. Is bolted on.
이와 같은 종래의 범퍼 구조는 차량 충돌시, 충돌 에너지가 상기 에너지 압소버(1)를 거쳐 범퍼빔(4)과 범퍼 스테이(2)로 전달되는바, 이중에서 상기 범퍼 스테이(2)는 길이 방향으로 충돌에너지를 전달받아 변형되는 변형에너지로서 충돌에너지를 흡수하므로, 가로 방향으로 충돌에너지를 전달받는 범퍼빔(4)이나, 완충재질의 에너지 압소버(1)에 비해 충격 흡수 능력이 가장 떨어지는 단점이 있었다.In the conventional bumper structure, collision energy is transmitted to the bumper beam 4 and the bumper stay 2 through the energy absorber 1 during the vehicle collision, in which the bumper stay 2 has a longitudinal direction. Since the collision energy is absorbed as the deformation energy that is deformed by receiving the collision energy, the shock absorbing ability is the lowest compared to the bumper beam 4 receiving the collision energy in the horizontal direction or the energy absorber 1 of the buffer material. there was.
본 고안은 이를 감안하여 고안한 것으로서, 범퍼 스테이의 완충능력을 보다 향상시켜 차량 충돌시 탑승자의 안전을 보다 확고히 확보할 수 있는 범퍼 스테이를 제공함에 그 목적이 있다.The present invention has been devised in view of this, and its purpose is to provide a bumper stay that can more securely secure the occupant's safety during a vehicle crash by improving the cushioning capacity of the bumper stay.
본 고안의 목적을 달성하기 위한 수단으로서는, 범퍼 스테이에 응력집중을 유도할 수 있는 노치를 플랜지에 형성하여 줌으로서 상기의 목적을 달성할 수가 있다.As a means for achieving the object of the present invention, the above object can be achieved by forming a notch on the flange that can induce stress concentration in the bumper stay.
이하 본 고안의 실시예를 제3도를 참조하여 설명하면 하기와 같다.Hereinafter, an embodiment of the present invention will be described with reference to FIG. 3.
범퍼 스테이(11)의 플랜지(12)에 응력집중을 유도할 수 있도록 다수의 마름모꼴형 노치(13'),(13)를 형성하여 준다.A plurality of rhombic notches 13 ', 13 are formed in the flange 12 of the bumper stay 11 to induce stress concentration.
미설명 부호 (14)는 프레임에 고정하기 위해 범퍼 스테이의 후단부에 형성한 볼트구멍이다.Reference numeral 14 is a bolt hole formed in the rear end of the bumper stay for fixing to the frame.
따라서, 본 고안의 노치를 형성한 범퍼 스테이를 범퍼 어셈블리에 적용하게 되면 충돌시 범퍼 스테이에 형성한 다수의 노치부에 충돌에너지의 응력집중이 일어나 범퍼 스테이의 변형이 촉진되고 범퍼 스테이의 완충능력이 보다 향상되므로 승객의 안전이 도모된다.Therefore, when the bumper stay having the notch of the present invention is applied to the bumper assembly, the stress concentration of the collision energy occurs due to the number of notches formed in the bumper stay during the collision, so that the deformation of the bumper stay is promoted and the buffering capacity of the bumper stay is increased. This further improves passenger safety.
