Description

차량의 루프패널 충격흡수구조(A structure for absorbing impact of a roof panel of an automobile)A structure for absorbing impact of a roof panel of an automobile

본 발명은 차량의 루프패널에 관한 것으로, 특히 충격 흡수 부재가 내장 설치된 차량의 루프패널 충격 흡수구조에 관한 것이다.The present invention relates to a roof panel of a vehicle, and more particularly to a roof panel shock absorbing structure of a vehicle provided with a built-in shock absorbing member.

일반적으로, 차량에는 사고시 탑승객의 부상을 방지하도록 여러가지 안전장치가 구비됨은 물론 특히, 얇은 여러 판넬들이 서로 접합되어 형성된 차체프레임은 그 내부로 충격에 따른 변형을 방지 하도록 내구성 강화용 보강부재가 구비 되지만, 타 부위에 비해 상대적으로 보강구조가 취약한 루프판넬은 충돌이나 추돌사고시에 그 충격을 제대로 흡수하지 못하여 승객의 머리에 손상이 가해지는 문제가 있었다.In general, the vehicle is equipped with a variety of safety devices to prevent injuries of passengers in the event of an accident, in particular, the body frame formed by joining a number of thin panels to each other is provided with a reinforcement member for durability to prevent deformation due to impact therein, However, the roof panel, which has a weaker reinforcement structure than other parts, has a problem that the head of the passenger is damaged due to a failure to properly absorb the impact during a collision or collision.

상기한 문제를 해결하기 위하여 종래에도 루프프레임 일측에 보강패널을 설치하여 충격 흡수와 강성을 보강하였었다.In order to solve the above problem, conventionally, a reinforcement panel was installed at one side of the loop frame to reinforce shock absorption and rigidity.

즉, 도 4에 도시된 바와 같이, 루프프레임(101)의 상단에 루프패널(102)이 용접부착되고, 내측에는 실내를 이루는 가니쉬(103)가 부착되며, 외측으로는 도어(104)가 위치하는 구조의 루프프레임에 있어서, 상기 가니쉬(103)와, 프레임(101) 사이에 충격흡수부재(105)가 설치되어 있는 구조로 되어 있다.That is, as shown in Figure 4, the roof panel 102 is welded to the upper end of the roof frame 101, the inside of the garnish 103 forming the room is attached, the door 104 is located outside In the loop frame having the structure described above, the shock absorbing member 105 is provided between the garnish 103 and the frame 101.

이에 따라 차량에 충돌 등의 사고가 발생한 경우 외부에서 가하는 충격이나 실내에서 승객의 머리 등이 상기 가니쉬에 부딛쳐 가해지는 충격 등에 의해 상기 충격흡수부재가 찌그러지면서 적절히 흡수하여 승객에게 손상이 가해지지 않게 되는 것이다.Accordingly, when an accident, such as a collision, occurs in the vehicle, the shock absorbing member is crushed and absorbed appropriately by an impact applied from the outside or an impact caused by the passenger's head or the like on the garnish in the room, thereby preventing damage to the passenger. Will be.

그런데 상기한 종래의 구조는 상기 충격흡수부재가 단일 강판으로 되어 상기 프레임의 양단에 용접되어 설치되는 바, 충격이 가해졌을 때 충분히 찌그러지지 않게 되어, 충격을 제대로 흡수할 수 없다는 문제점이 있었다.However, the conventional structure has a problem in that the impact absorbing member is made of a single steel plate and is welded to both ends of the frame so that the impact absorbing member is not sufficiently crushed when the impact is applied, so that the impact cannot be properly absorbed.

이에 본 발명은 상기한 바와 같은 종래의 문제점을 해소하기 위해 안출된 것으로, 루프프레임에 용접설치되는 충격흡수부재에 홀을 형성하여 충격이 가해졌을 때 용이하게 찌그러지면서 충격을 흡수할 수 있도록 된 차량의 루프패널 충격 흡수구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the conventional problems as described above, the vehicle is formed so that the shock absorbing member to be welded to the roof frame can be easily distorted when the shock is applied to absorb the shock The purpose of the present invention is to provide a roof panel shock absorbing structure.

상기한 바와 같은 목적을 달성하기 위한 본 발명은, 루프프레임의 상단에 루프패널이 용접부착되고, 내측에는 실내를 이루는 가니쉬가 부착되며, 상기 가니쉬와 프레임 사이에 충격흡수부재가 설치되어 있는 구조의 루프프레임에 있어서, 상기 충격흡수부재가 전면에 다수개의 홀이 형성되어 있는 것을 특징으로 한다.The present invention for achieving the object as described above, the roof panel is welded to the upper end of the roof frame, the interior of the garnish attached to the interior, and the structure of the shock absorbing member is installed between the garnish and the frame. In the loop frame, the shock absorbing member is characterized in that a plurality of holes are formed in the front.

상기한 구조로 되어, 탑승객의 머리 등이 상기 루프를 이루는 가니쉬에 부딛치게 되면, 가니쉬 내측의 충격흡수부재가 찌그러들면서 충격을 제대로 흡수하여 승객의 상해를 최소로 줄일 수 있게 되는 것이다.With the above structure, when the passenger's head or the like hits the garnish forming the loop, the shock absorbing member inside the garnish is crushed to properly absorb the shock to reduce the passenger's injury to a minimum.

도 1은 본 발명에 따른 차량 루프패널의 적용부위를 나타내기 위한 차량의 개략적인 사시도이고, 도 2는 본 발명에 따른 도 1의 A-A 선 단면도이며, 도 3은 본 발명에 따른 충격흡수부재를 도시한 개략적인 사시도이다.1 is a schematic perspective view of a vehicle for showing an application portion of a vehicle roof panel according to the present invention, Figure 2 is a cross-sectional view taken along line AA of Figure 1 according to the present invention, Figure 3 is a shock absorbing member according to the present invention It is a schematic perspective view.

상기한 도면에 의하면, 루프프레임(10)의 상단에 루프패널(20)이 용접부착되고, 내측에는 실내를 이루는 가니쉬(30)가 부착되며, 상기 가니쉬(30)와 프레임(10) 사이에 충격흡수부재(40)가 설치되어 있는 구조의 루프프레임에 있어서, 상기 충격흡수부재(40)가 전면에 다수개의 홀(41)이 형성되어 있는 것을 특징으로 한다.According to the above drawings, the roof panel 20 is welded to the upper end of the roof frame 10, and the inside of the garnish 30 forming the room is attached, and the impact between the garnish 30 and the frame 10 In the loop frame of the structure in which the absorbing member 40 is installed, the shock absorbing member 40 is characterized in that a plurality of holes 41 are formed on the front surface.

즉, 도 3에 도시된 바와 같이, 루프프레임(10)과 용접되어 소정의 공간을 이룰 수 있도록 플랜지(42)를 형성하면서 절곡되어 있는 충격흡수부재(40)의 전면에 소정 직경의 홀(41)이 다수개 형성되어 있는 구조로 되어 있다.That is, as shown in FIG. 3, the hole 41 having a predetermined diameter is formed on the front surface of the shock absorbing member 40 that is bent while forming the flange 42 to be welded with the loop frame 10 to form a predetermined space. It has a structure in which a plurality of) are formed.

상기한 구조로 되어 상기 충격흡수부재(40)의 전면에 충격이 가해졌을 때 상기 홀(41)에 의해 상기 부재(40)의 찌그러짐이 양호해지게 되는 것이다.When the impact is applied to the front surface of the shock absorbing member 40, the structure of the structure is to be satisfactory crushing of the member 40 by the hole 41.

따라서, 탑승객의 머리 등이 상기 루프를 이루는 가니쉬(30)에 부딛치게 되면, 가니쉬(30) 내측의 충격흡수부재(40)가 찌그러들면서 충격을 제대로 흡수하여 승객의 상해를 최소로 줄일 수 있게 되는 것이다.Therefore, when the passenger's head or the like hits the garnish 30 forming the loop, the shock absorbing member 40 inside the garnish 30 is crushed, so as to properly absorb the impact to reduce the passenger's injury to a minimum. will be.

여기서 상기 충격흡수부재(40)에 형성되는 홀(41)의 직경이나 갯수는 필요한 요구치에 맞게 형성시킴이 바람직하다.In this case, the diameter or number of holes 41 formed in the shock absorbing member 40 is preferably formed according to a required requirement.

이상에서 설명한 바와 같이 본 발명에 따른 차량의 루프패널 충격흡수구조에 의하면, 루프프레임에 용접설치되는 충격흡수부재의 충격흡수능력을 향상시켜 차량 충돌시 승객의 상해를 최소화할 수 있게 되는 것이다.As described above, according to the roof panel shock absorbing structure of the vehicle according to the present invention, the impact absorbing ability of the shock absorbing member welded to the roof frame may be improved, thereby minimizing passenger injury.
