자동차용 범퍼 구조{Structure of bumper for automobile}Structure of bumper for automobile

본 발명은 자동차용 범퍼 구조에 관한 것으로서, 더욱 상세하게는 범퍼 커버의 이면에 충돌을 감지하는 충돌 감지 센서를 장착하고, 범퍼빔 내부에 상기 충돌 감지 센서와 연계되어 고압의 가스 폭발 압력을 발생하는 가스 인플레이터와, 상기 가스 인플레이터의 폭발 압력에 의해 가이드바를 따라 전방으로 전진하는 충격 완화 패널로 구성되어, 자동차의 추돌 사고시에 상기 충돌 완화 수단의 완충 작용으로 인해 충격을 흡수할 수 있는 자동차용 범퍼 구조에 관한 것이다.The present invention relates to a bumper structure for an automobile, and more particularly, includes a collision detection sensor detecting a collision on a rear surface of a bumper cover, and generating a high pressure gas explosion pressure in connection with the collision detection sensor inside a bumper beam. A bumper structure for automobiles, comprising a gas inflator and a shock absorbing panel moving forward along the guide bar due to the explosion pressure of the gas inflator, and capable of absorbing shock due to the buffering action of the collision mitigating means in the event of a collision of the car. It is about.

일반적으로, 자동차에는 충돌시에 그 충격을 흡수하여 탑승자 등을 보호하기 위해 차체의 전방 및 후방에 범퍼가 장착되어있는 바, 이와 같은 종래의 범퍼는 도 3에 도시된 바와 같이, 범퍼(10)의 외관미를 향상시키기 위한 범퍼 커버(11)와, 이 범퍼 커버(11)의 이면에 부착되어 충격을 1차적으로 흡수하는 발포고무와 같은 충격 흡수재(12)를 갖춘 구조로 되어 있다.In general, the bumper is mounted on the front and rear of the vehicle body to absorb the shock during a collision to protect the occupants and the like, such a conventional bumper is shown in Figure 3, the bumper 10 The bumper cover 11 for improving the appearance and the impact absorbing material 12, such as foam rubber attached to the rear surface of the bumper cover 11 to absorb the impact primarily.

그리고, 상기 충격 흡수재(12) 만으로는 차량 충돌시에 탑승자 등을 보다 효과적으로 보호하기가 미흡하기 때문에 대개는 스틸 재질로 된 범퍼빔(13)이 상기 충격 흡수재(12)의 이면에 결합되고, 이 범퍼빔(13)은 범퍼 스테이(14)를 매개로 프레임(15)에 볼트 체결되어 범퍼를 전체적으로 지지하도록 되어 있다.In addition, since the shock absorber 12 alone is insufficient to more effectively protect occupants and the like during a vehicle crash, a bumper beam 13 usually made of steel is coupled to the rear surface of the shock absorber 12. The beam 13 is bolted to the frame 15 via the bumper stay 14 so as to support the bumper as a whole.

한편, 종래의 범퍼는 도 3에 도시된 바와 같이, 자동차의 충돌이나 추돌시에 먼저 충격 흡수재(12)가 충격을 1차적으로 흡수하고, 여분의 충격은 범퍼빔(13)에 전달되어 범퍼빔(13)이 충격을 적절히 흡수함과 동시에 상기 범퍼 스테이(14)를 통하여 프레임(15)으로 분산시켜 탑승자 쪽으로 가능한 한 충격이 적게 전달되도록 하여 탑승자 등을 보호하고 있다.Meanwhile, in the conventional bumper, as shown in FIG. 3, the shock absorber 12 first absorbs the shock during collision or collision of the vehicle, and the extra shock is transmitted to the bumper beam 13 to the bumper beam. (13) absorbs the impact appropriately and at the same time is distributed to the frame (15) through the bumper stay (14) to protect the occupants and the like so that the impact is transmitted to the occupant as little as possible.

그런데, 종래의 범퍼의 구조는 자동차의 추돌 사고시와 같은 큰 외부 충격에범퍼 이외에는 충격을 흡수할 수 있는 구조가 없어 차량 손상이 커지므로 그로 인해 실내에 탑승한 운전자 및 탑승자가 상해를 입게 되는 문제점이 있다.However, the conventional bumper structure has a problem that the driver and the occupant in the room are injured because the damage to the vehicle is increased because there is no structure that can absorb the shock other than the bumper due to a large external shock such as a car crash. have.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 범퍼 커버의 이면에 충돌을 감지하는 충돌 감지 센서를 장착하고, 범퍼빔 내부에 상기 충돌 감지 센서와 연계되어 고압의 가스 폭발 압력을 발생하는 가스 인플레이터와, 상기 가스 인플레이터의 폭발 압력에 의해 가이드바를 따라 전방으로 전진하는 충격 완화 패널로 구성되어, 자동차의 추돌 사고시에 상기 충돌 완화 수단의 완충 작용으로 인해 충격을 흡수할 수 있는 자동차용 범퍼 구조를 제공하는데 그 안출의 목적이 있다.Accordingly, the present invention has been made in view of the above problems, and equipped with a collision detection sensor for detecting a collision on the rear surface of the bumper cover, and generates a high pressure gas explosion pressure in connection with the collision detection sensor inside the bumper beam. Bumper for automobile which is composed of a gas inflator and a shock alleviation panel that moves forward along the guide bar by the explosion pressure of the gas inflator, and can absorb the shock due to the buffering action of the collision mitigation means in the event of a collision of the car. Its purpose is to provide a structure.

여기서, 도면부호 10은 범퍼를 나타낸다.Here, reference numeral 10 denotes a bumper.

상기 범퍼(10)에는 스틸 재질로 되고, 충격 흡수재(12)의 이면에 결합되며, 범퍼 스테이(14)를 매개로 프레임(15)에 볼트 체결되어 범퍼(10)를 전체적으로 지지하는 범퍼빔(13)이 설치되어 있는 바, 상기 범퍼빔(13)의 내부에는 전방을 향하도록 가스 인플레이터(16)가 장착되어 있다.The bumper 10 is made of steel, is coupled to the rear surface of the shock absorber 12, and is bolted to the frame 15 via the bumper stay 14 to support the bumper 10 as a whole bumper beam 13 Is installed, the gas inflator 16 is mounted inside the bumper beam 13 to face forward.

또한, 상기 가스 인플레이터(16)는 충돌 감지 센서(17)의 센서 변형을 인식하는 전자 제어 장치(18)의 전기 신호에 의해 폭발하게 되는데, 작약, 점화제, 가스 발생제등으로 구성되어 있다.In addition, the gas inflator 16 is to be exploded by the electrical signal of the electronic control device 18 that recognizes the sensor deformation of the collision detection sensor 17, it is composed of a charge, an ignition agent, a gas generator.

상기 가스 인플레이터(16)의 전방에는 충격 완화 패널(19)이 구비되어 있는바, 상기 충격 완화 패널(19)은 상기 가스 인플레이터(16)의 폭발에 의해 전방으로 진행하게 되어 자동차의 추돌 사고시에 충격을 상쇄시키는 기능을 한다.A shock absorbing panel 19 is provided at the front of the gas inflator 16, and the shock absorbing panel 19 proceeds forward by the explosion of the gas inflator 16, thereby impacting the collision of the vehicle. Function to cancel.

또한, 상기 충격 완화 패널(19)은 가이드바(20)를 따라 슬라이드 이동될 수 있도록 장착되며, 자동차의 추돌 사고시에 가스 인플레이터(16)의 폭발에 의해 동시에 전방에 위치한 충격 흡수재(12)에 충격을 가하여 자동차의 추돌에 의한 충격이 상호 상쇄되게 됨으로써, 자동차에 탑승한 운전자 및 탑승자에게 오는 충격이 저감되므로 상기 운전자 및 탑승자의 상해치를 저감시킬 수 있다.In addition, the shock absorbing panel 19 is mounted to be slidably moved along the guide bar 20, and impacts the shock absorber 12 located at the same time at the same time by the explosion of the gas inflator 16 during the collision of the vehicle. By adding the impact to the impact of the collision of the car to be mutually offset, the impact on the driver and the occupant in the car is reduced, so that the injury value of the driver and the occupant can be reduced.

이상에서 상술한 바와 같이, 본 발명에 따른 자동차용 범퍼 구조는 범퍼 충돌 성능을 향상시킬 뿐만 아니라, 차체 및 엔진룸내의 부품 손상을 감소시킴으로써, 차량에 탑승한 운전자 및 탑승자의 상해를 저감시킬 수 있는 효과가 있다.As described above, the bumper structure for automobiles according to the present invention not only improves bumper collision performance, but also reduces damage to parts in the vehicle body and the engine compartment, thereby reducing injuries of drivers and occupants on the vehicle. It works.
