Abstract
본 고안은 차량의 범퍼 스테이 완충구조에 관한 것으로서, 자동차의 범퍼 스테이에 고무링을 개재시켜 차량 충돌시 범퍼 스테이의 변형에너지와 고무링의 탄성에너지로서 충돌에너지를 흡수할 수 있도록 한 것이다.The present invention relates to a bumper stay shock absorbing structure of a vehicle, by interposing a rubber ring in a bumper stay of a vehicle so as to absorb the collision energy as the deformation energy of the bumper stay and the elastic energy of the rubber ring during a vehicle crash.
이와 같이 형성되는 본 고안은 상기 범퍼 스테이의 중간부에 형성한 벨로우즈의 형상에 의해, 차량 충돌시 상기 범퍼 스테이의 변형이 원활히 일어나고, 또한 상기 홈에 삽입한 고무링이 충격에너지를 탄성에너지로 저장하므로, 상기 에너지 압소버 및 범퍼빔과 더불어 차량의 충돌시 완충효과가 극대화할 수 있는 효과가 있다.According to the present invention, the bellows is formed in the middle portion of the bumper stay, so that the bumper stay is easily deformed during a vehicle crash, and the rubber ring inserted into the groove stores the impact energy as elastic energy. Therefore, in addition to the energy absorber and the bumper beam, there is an effect that can maximize the buffering effect during the collision of the vehicle.

본 고안은 차량의 범퍼 스테이 완충구조에 관한 것으로서, 자동차의 범퍼 스테이에 고무링을 개재시켜 차량 충돌시 범퍼 스테이의 변형 에너지와 고무링의 탄성에너지로서 충돌에너지를 흡수할 수 있도록 한 것이다.The present invention relates to a bumper stay shock absorbing structure of a vehicle, wherein a rubber ring is interposed between a bumper stay of a vehicle to absorb the collision energy as the deformation energy of the bumper stay and the elastic energy of the rubber ring during the vehicle collision.
범퍼는 자동차가 다른 자동차 또는 물체와 충돌하였을 때, 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 body damage when the vehicle collides with another vehicle or an object.
종래의 범퍼 구조는 제1(a)도에 도시한 바와 같이, 차량의 충격을 흡수 완화할 수 있는 에너지 압소버(1)와, 상기 에너지 압소버(1)를 고정하며 범퍼 스테이(2)에 의해 프레임(3)에 지지되는 범퍼빔(4)으로 구성된다.The conventional bumper structure has an energy absorber (1) capable of absorbing and mitigating a shock of a vehicle, and fixing the energy absorber (1) to the bumper stay (2), as shown in FIG. It consists of the bumper beam 4 supported by the frame 3 by this.
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 is a fascia wrapped with an energy absorber to improve the appearance of the vehicle.
이와 같은 종래의 범퍼 구조는 차량 충돌시, 충돌 에너지가 상기 에너지 압소버(1)를 거쳐 범퍼빔(4)와 범퍼 스테이(2)로 전달되는 바, 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 is longitudinally 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.
이에대하여 제2도와 같은 형태의 차량용 충격흡수프레임(10)이 알려져 있다. 이 프레임(10)은 측벽에 변형 가능한 노치(10A) 및 장방형의 융기부(10B)를 두어 충격에 대하여 프레임(10)의 변형을 꾀하고자 하였으나, 프레임(10)의 변형을 통한 충격흡수 능력이 떨어지고, 주로 대형차에 적용되어 승용차에 적용하기에는 어려운 문제점이 있다.On the other hand, a vehicle shock absorbing frame 10 of the type shown in FIG. 2 is known. The frame 10 has a deformable notch 10A and a rectangular ridge 10B on the side wall to deform the frame 10 against impact, but the shock absorbing ability of the frame 10 is deformed. There is a problem that is difficult to apply to a car, mainly falling large vehicles.
본 고안은 이를 감안하여 고안한 것으로서, 범퍼 스테이의 완충능력을 보다 향상시켜 차량 충돌시 탑승자의 안전을 보다 확고히 확보할 수 있는 범퍼 스테이 완충 구조를 제공함에 그 목적이 있다.The present invention has been devised in view of this, and its object is to provide a bumper stay buffer structure that can more securely secure the occupant's safety in a vehicle crash by further improving the buffer capacity of 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.
범퍼빔(11)을 지지하고 프레임(12)에 의해 고정되는 범퍼 스테이(13)의 중간부에 벨로우즈(14)를 형성하고, 상기 벨로우즈(14)의 형성으로 상기 범퍼 스테이(13)의 내측면에 형성된 다수의 홈(15)에 고무링(16)을 삽입한다.A bellows 14 is formed in the middle of the bumper stay 13 that supports the bumper beam 11 and is fixed by the frame 12, and the bellows 14 forms an inner surface of the bumper stay 13. The rubber ring 16 is inserted into the plurality of grooves 15 formed in the groove.
미설명 부호(17)는 에너지 압소버이고, (18)는 훼시아이다.Reference numeral 17 is an energy absorber, and 18 is a fascia.
이와같이 구성되는 본 고안은 상기 범퍼 스테이(13)의 중간부에 형성한 벨로우즈(14)의 형상에 의해, 차량 충돌시 상기 범퍼 스테이(13)의 변형이 원활히 일어나고, 또한 상기 홈(15)에 삽입한 고무링(16)이 충격에너지를 탄성에너지로 저장하므로, 상기 에너지 압소버(17) 및 범퍼빔(11)과 더불어 차량의 충돌시 완충효과가 극대화할 수 있는 효과가 있다.According to the present invention configured as described above, due to the shape of the bellows 14 formed at the middle portion of the bumper stay 13, deformation of the bumper stay 13 occurs smoothly when the vehicle collides and is inserted into the groove 15. Since the rubber ring 16 stores the impact energy as elastic energy, the energy absorber 17 and the bumper beam 11, together with the energy absorber, have the effect of maximizing the cushioning effect during the collision of the vehicle.
따라서 충돌에너지 흡수 능력이 향상될 필요가 있는 소형차에 적용이 유리하다.Therefore, it is advantageous to apply to the compact car which needs to improve the collision energy absorption capacity.
