Description
본 발명은 자동차의 사이드실(side sill)에 관한 것으로, 더 상세하게는 차량의 측면충돌시 사이드실의 전방부에서 충분한 충격흡수를 수행할 수 있도록 사이드실의 측면강성을 증대시켜, 차량의 측면충돌시 실내밀림량 감소 및 차내의 승객에게 전달되는 충격량을 최대한 줄여 승객 상해치 저하와 자동차의 안전성을 향상시킬 수 있도록 한 자동차의 사이드실 측면강성 보강구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side sill of a vehicle, and more particularly, to increase side stiffness of the side sill so as to sufficiently absorb shock at the front of the side sill in the event of a side collision of the vehicle. The present invention relates to a side seal stiffness reinforcement structure of a vehicle to reduce the amount of indoor sliding during a collision and reduce the amount of impact transmitted to passengers in a vehicle, thereby reducing passenger injury and improving vehicle safety.
일반적으로 자동차의 충돌사고시 승객의 안전성을 확보하기 위한 테스트로는 전방충돌과 측면충돌이 있으며, 이는 자동차의 안전성을 확보하는 중요한 요소로서 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제 등의 큰 항목으로 이용하고 있다.In general, there are front and side collision tests to ensure the safety of passengers in the event of a car crash. This is an important factor to secure the safety of cars. We use with big item of.
그러나, 현재 생산되고 있는 자동차는 대부분이 전방충돌에 대한 안전치는 어느 정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다.However, most of the automobiles currently produced have some safety values for forward collisions, but the safety values for side collisions are insufficient.
그 원인으로는 차체의 사이드실 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시 사이드실의 전방부에서 충분한 충격흡수를 유도하지 못하여 사이드실이 실내로 밀리면서 센터필러,도어,루프상단까지 변형이 오고, 이로 인해 인체상해치가 커지기 때문이다.The reason is that the structure of the side seal of the car body is fragile. In fact, when the side collision with another vehicle does not induce sufficient shock absorption from the front part of the side seal, the side seal is pushed into the interior and the center pillar, the door and the top of the roof This is due to deformation, which increases the injury to the human body.
종래 자동차의 사이드실 구조는 도 2 에 도시되는 바와 같이, 센터플로어패널(1)의 외측으로 사이드실이너패널(2)과 사이드실아웃터패널(3)이 결합되어 사이드실박스(4)를 구성한다.As shown in FIG. 2, the side seal structure of the related art vehicle includes a side seal inner panel 2 and a side seal outer panel 3 coupled to the outside of the center floor panel 1 to form a side seal box 4. do.
따라서, 이와 같이 구성된 종래의 사이드실 구조는 그 지지기반이 매우 취약하기 때문에 외부로 부터 차량이 측면으로 충돌해 왔을 때 사이드실박스(4)에서 충분한 충격흡수가 되지 않고, 이로 인해 각각의 패널이 실내로 밀리게 되므로 센터필러와 도어 및 루프상단까지 변형이 초래되어 인체상해치가 커지게 되는 문제점이 있었다.Therefore, the conventional side seal structure configured as described above is very weak in its support base, and thus, when the vehicle has collided to the side from the outside, sufficient shock absorption is not absorbed in the side seal box 4, so that each panel is Since it is pushed into the room, the deformation of the center pillar, the door and the roof top is caused, resulting in a large injury to the human body.
즉, 상기와 같은 종래의 사이드실 구조는 차량의 측면충돌시 사이드실박스(4)의 실내밀림량이 과다하여 차내 승객이 받는 상해치가 커지는 문제점과, 이로 인하여 자동차의 안전성이 떨어지는 문제점이 있었다.That is, the conventional side seal structure as described above has a problem in that the amount of inward slip of the side seal box 4 is excessive when the side collision of the vehicle is excessive, resulting in a large injury value to passengers in the vehicle, and thus, the safety of the vehicle is lowered.
본 발명의 목적은 차량의 측면충돌시 사이드실의 전방부에서 충분한 충격흡수를 수행할 수 있도록 사이드실의 측면강성을 증대시켜, 차량의 측면충돌시 실내밀림량 감소 및 차내의 승객에게 전달되는 충격량을 최대한 줄여 승객 상해치 저하와 자동차의 안전성을 향상시킬 수 있도록 한 자동차의 사이드실 측면강성 보강구조를 제공하는 데 있다.An object of the present invention is to increase the side stiffness of the side seal to perform a sufficient shock absorption in the front of the side seal during the side impact of the vehicle, reducing the amount of room slip when the side impact of the vehicle and the amount of impact delivered to the passengers in the vehicle It is to provide a side stiffness reinforcement structure of a vehicle to reduce passenger injury and to improve safety of the vehicle.
상기 목적을 달성하기 위해 본 발명은 사이드실박스내에 절곡성형된 보강패널들을 결합하여 사이드실박스내의 상,하부 및 전방부에 각각 구획되는 공간부를 형성시키고, 상기 사이드실박스내에 형성된 각 공간부내에는 완충스프링, 완충부재, 사이드빔, 압축패드를 각각 장착하여, 차량의 측면충돌시 사이드실박스의 강성증대로 실내밀림량을 최대한 억제시키도록 한 것이다.In order to achieve the above object, the present invention combines the reinforcement panels bent in the side seal box to form a space portion respectively partitioned in the upper, lower and front portions in the side seal box, in each space formed in the side seal box The shock absorbing spring, the cushioning member, the side beam, and the compression pad are respectively installed so as to minimize the amount of indoor slippage by increasing the rigidity of the side seal box during the side collision of the vehicle.
