Description

차량의 전방추돌시 충격을 이중으로 감쇠하는 충격완화 장치{A shock absorber that doubly attenuates the impact of Vehicle forward collision}A shock absorber that doubly attenuates the impact of Vehicle forward collision}

본 발명은 차량의 전방 추돌 시 발생하는 충격을 이중으로 감쇠하는 충격완화 장치에 관한 것으로서, 좀 더 구체적으로는 전방 추돌로 발생하는 충격으로 엔진룸이 실내공간으로 밀려들어 오는 것을 억제하기 위하여 대시 패널의 전방에서 충격을 이중으로 감쇠하도록 구성된 충격완화 장치에 관한 것이다.The present invention relates to a shock mitigation device for doubly attenuating an impact generated during a frontal collision of a vehicle, and more particularly, to a dash panel for suppressing an impact generated in a frontal collision from pushing an engine room into an interior space. It relates to a shock mitigation device configured to attenuate an impact in front of a doubly.

주지된 바와 같이 차량은 엔진과 상대부품이 위치하는 엔진룸과 운전자와 탑승객이 승하차하는 실내공간, 짐을 싣는 트렁크로 구분되며, 엔진룸과 실내공간의 사이에는 서로의 공간을 구분하기 위한 대시 패널이 설치된다.As is well known, a vehicle is divided into an engine room where the engine and other parts are located, an interior space where drivers and passengers get on and off, and a trunk for loading luggage. installed

이러한 대시 패널은 엔진룸에서 발생하는 소음과 열기가 실내공간으로 유입되는 것을 차단하며 차량의 전방 추돌 및 충돌 시 엔진룸에 위치하는 엔진과 상대부품이 실내공간으로 밀려 들어오는 것을 방지하는 역할을 한다.Such a dash panel blocks noise and heat generated in the engine room from entering the interior space, and serves to prevent the engine and counterpart parts located in the engine room from being pushed into the interior space in the event of a frontal collision or collision of a vehicle.

종래의 대시 패널은 소음을 차폐하기 위하여 흡음재 등을 도포하며 강성의 향상을 위하여 소정의 굴곡지는 형상을 가지고, 대시 패널을 외부 패널에 용접하여 결합력을 강화하여 전방 추돌 및 충돌 시 엔진룸이 실내공간으로 밀고 들어오는 것을 차단하도록 구성되어 있다.A conventional dash panel is coated with a sound-absorbing material to shield noise, has a predetermined curved shape to improve rigidity, and welds the dash panel to an external panel to strengthen bonding strength so that the engine room can be installed in the interior space in the event of a frontal collision or collision. It is configured to block push-in.

그러나, 결합력을 강화하기 위해 외부 패널과 용접한 대시 패널은 차량의 전방 추돌 및 충돌 시 발생하는 강한 충격력(衝擊力)을 견디기 어려운 문제가 있다.However, the dash panel welded to the outer panel in order to strengthen the binding force has a problem in that it is difficult to withstand strong impact force generated during a frontal collision or collision of a vehicle.

또한, 차량의 전후방에 외부 충돌에 대응하기 위한 우레탄 등과 같이 완충부재로 구성되어 충격을 저감 또는 감쇠하기 위한 수단이 차량의 연비 상승을 이유로 부피나 무게 등을 줄이면서 제한적으로 설치되면서 차량의 충돌 시 충격으로 엔진룸이 실내공간으로 밀고 들어오는 것을 차단하지 못하여 운전자와 탑승자를 효과적으로 보호하기 어려운 문제가 있다.In addition, as means for reducing or attenuating shocks composed of buffer members such as urethane to respond to external collisions are installed on the front and rear of the vehicle in a limited way while reducing the volume or weight for reasons of increased fuel efficiency, There is a problem in that it is difficult to effectively protect the driver and occupants because the engine room cannot block the impact from pushing into the interior space.
