본 발명은 자동차용 펜더패널 마운팅부의 충격흡수구조에 관한 것으로서, 보다 상세하게는 펜더패널과 그 하부의 펜더에이프런멤버 사이에 충격흡수가 이루어지는 충격흡수브래킷을 설치하여 보행자 충돌시 보행자의 머리가 펜더패널과 부딪칠 때 펜더패널의 변형을 유도함으로써 충격흡수가 이루어지도록 한 자동차용 펜더패널 마운팅부의 충격흡수구조에 관한 것이다.The present invention relates to a shock absorbing structure of an automobile fender panel mounting portion, and more specifically, to install a shock absorbing bracket between the fender panel and the lower fender apron member, the head of the pedestrian during the pedestrian collision. The present invention relates to a shock absorbing structure of an automobile fender panel mounting portion in which a shock absorber is made by inducing deformation of a fender panel when colliding with the sheet.

일반적으로 자동차의 후드패널이나 펜더패널에는 보행자가 충돌하는 경우 상기 후드패널이나 펜더패널이 소성 변형되도록 함으로써 보행자에게 전해지는 충격을 최대한 흡수하여 보행자의 상해정도를 최소화시킬 것이 요구된다.In general, when the pedestrian collides with the hood panel or the fender panel of the vehicle, the hood panel or the fender panel is plastically deformed so as to absorb the impact transmitted to the pedestrian as much as possible to minimize the degree of injury of the pedestrian.

도1은 일반적인 차량의 사시도이고, 도2는 도1의 A-A부위를 나타낸 단면도이다. 종래의 펜더패널 고정구조는 도2에 도시된 바와 같이 자동차의 후드패널(1) 하부에 위치되는 펜더에이프런멤버(에이프런 인너패널과 에이프런 아웃터패널로 구분됨)(2)의 상면에 펜더패널(3) 끝단의 절곡부(3a) 하면이 얹혀지고 그 얹혀진 펜더패널(3)의 절곡부(3a)와 펜더에이프런멤버(2)는 상호 용접 또는 볼트체결 등의 방법으로 고정된다.FIG. 1 is a perspective view of a general vehicle, and FIG. 2 is a cross-sectional view showing a portion A-A of FIG. Conventional fender panel fixing structure has a fender panel (3) on the upper surface of the fender apron member (divided into an apron inner panel and an apron outer panel) (2) located under the hood panel (1) of the vehicle as shown in FIG. The lower surface of the bent portion 3a of the end is mounted, and the bent portion 3a and the fender apron member 2 of the mounted fender panel 3 are fixed by a method such as mutual welding or bolting.

상기 펜더에이프런멤버(2)는 펜더패널(3)의 내측에 위치되는 부재로서 서스펜션(미도시)이 지지되도록 소정의 강도 및 강성을 보유하고 있다. 또한, 상기 펜더패널(3)은 자동차의 휠 하우스 상부에 위치되는 패널로서 그 끝단은 상기 펜더에이프런멤버(2)에 마운팅된다.The fender apron member 2 is a member located inside the fender panel 3 and has a predetermined strength and rigidity so that a suspension (not shown) is supported. In addition, the fender panel 3 is a panel located above the wheel house of the vehicle, the end of which is mounted to the fender apron member 2.

그러나 종래와 같은 펜더패널 고정구조에서는 펜더에이프런멤버(2)의 상부에 펜더패널(3)의 끝단부가 수직하게 내려와서 마운팅되므로 그 부위의 강도가 국부적으로 높다. 따라서, 보행자의 머리가 펜더에이프런멤버(2)에 마운팅되는 펜더패널(3)과 충돌하게 되면 그 펜더패널(3)의 충격흡수가 제대로 이루어지지 않아 보행자 충돌에 따른 충돌에너지는 보행자에게 그대로 전달되어 보행자의 머리부위 상해치(HIC)가 높아지는 문제점이 있다.However, in the conventional fender panel fixing structure, the end portion of the fender panel 3 is vertically mounted on the top of the fender apron member 2 so that the strength of the portion is locally high. Therefore, when the head of the pedestrian collides with the fender panel 3 mounted on the fender apron member 2, the shock absorption of the fender panel 3 is not properly performed, and the collision energy due to the pedestrian collision is transmitted to the pedestrian as it is. There is a problem that the head injury (HIC) of the pedestrian is increased.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 보행자가 펜더패널과 충돌할 때 그 펜더패널이 충분히 변형되어 충격에너지가 흡수될 수 있도록 펜더패널과 그 하부의 펜더에이프런멤버 사이에 충격흡수가 가능한 충격흡수브래킷을 설치하여 펜더패널에 가해지는 충격이 흡수되도록 함으로써 보행자 충돌사고 발생시 보행자의 머리를 보호하는데 있다. The present invention has been proposed to solve the problems described above, and its object is to provide a sufficient deformation of the fender panel when the pedestrian collides with the fender panel so that the impact energy is absorbed, and the fender apron member below the fender panel. The shock absorbing bracket that can absorb the shock between the two to prevent the impact on the fender panel to protect the head of the pedestrian in the event of a pedestrian crash.

상기의 목적을 달성하기 위한 본 발명은, 자동차 후드패널과 펜더패널이 이루는 경계부 하부에 위치되는 펜더에이프런멤버에 상기 펜더패널의 상부 끝단이 마운팅되는 자동차용 펜더패널의 마운팅구조에 있어서, 상기 펜더패널의 상부 끝단과 상기 펜더에이프런멤버 사이에는 펜더패널로부터 하방으로 가해지는 충격을 흡수하도록 상부는 좁고 하부는 넓은 충격흡수브래킷이 설치된 자동차용 펜더패널 마운팅부의 충격흡수구조이다.In the present invention for achieving the above object, in the mounting structure of the automotive fender panel is mounted on the upper end of the fender panel to the fender apron member located under the boundary formed between the vehicle hood panel and the fender panel, the fender panel Between the upper end of the and the fender apron member is a shock absorbing structure of the car fender panel mounting portion is installed in the upper and narrow upper and lower shock absorbing bracket to absorb the impact applied downward from the fender panel.

이하, 본 발명의 구성을 첨부된 도면에 의거하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on attached drawing.

도3은 펜더에이프런멤버와 펜더패널 사이에 충격흡수브래킷이 설치된 상태를 나타낸 사시도이고, 도4a 및 도4b는 본 발명에 따른 펜더패널 마운팅부의 충격흡수구조를 나타낸 단면도 및 작용 상태도이다.3 is a perspective view showing a state in which a shock absorbing bracket is installed between a fender apron member and a fender panel, and FIGS. 4A and 4B are cross-sectional views and a functional state diagram illustrating a shock absorbing structure of a fender panel mounting unit according to the present invention.

이상의 도면에서 살펴보면, 자동차의 후드패널(1) 하부에는 차체의 길이방향으로 배치되는 펜더에이프런멤버(2)가 마련되고, 상기 펜더에이프런멤버(2)의 외측에는 펜더패널(3)이 위치되어 전방차체의 양측을 커버하게 된다.Referring to the drawings, the fender apron member 2 disposed in the longitudinal direction of the vehicle body is provided under the hood panel 1 of the vehicle, and the fender panel 3 is positioned outside the fender apron member 2 to the front. It covers both sides of the vehicle body.

여기서, 상기 펜더에이프런멤버(2)는 후드패널(1)과 펜더패널(3)이 이루는 경계부 하부에 위치되는 강도 및 강성이 큰 구조물로서 통상적으로 상기 펜더패널(3)의 상부 끝단이 이 펜더에이프런멤버(2)의 상부에 마운팅된다.Here, the fender apron member 2 is a structure having a high strength and rigidity located under the boundary formed by the hood panel 1 and the fender panel 3, and the upper end of the fender panel 3 is typically the fender apron. It is mounted on top of the member 2.

상기 펜더패널(3)은 자동차의 앞바퀴가 위치되는 휠 하우스의 상부를 커버하면서 후드패널(1) 쪽으로 연장되어 그 끝단이 상기 펜더에이프런멤버(2)에 마운팅되는데, 본 발명에서는 펜더패널(3)의 끝단부와 펜더에이프런멤버(2) 사이에 충격흡수브래킷(10)이 설치된다.The fender panel 3 extends toward the hood panel 1 while covering the upper portion of the wheel house in which the front wheel of the vehicle is located, and its end is mounted on the fender apron member 2. In the present invention, the fender panel 3 The shock absorbing bracket 10 is installed between the end portion of the fender apron member (2).

상기 충격흡수브래킷(10)은 펜더패널(3)에 수직한 방향으로 입력되는 외력, 즉 충돌시의 충격에너지에 대하여 변형될 수 있는 구조로 설치되어야 한다. 따라서, 상기 펜더패널(3)과 펜더에이프런멤버(2) 사이에는 소정의 공간이 형성되어야 하고, 그 공간에 차체 길이방향으로 일정간격을 갖는 다수개의 충격흡수브래킷(10)이 설치된다.The shock absorbing bracket 10 should be installed in a structure that can be deformed with respect to the external force input in the direction perpendicular to the fender panel 3, that is, the impact energy at the time of impact. Therefore, a predetermined space must be formed between the fender panel 3 and the fender apron member 2, and a plurality of shock absorbing brackets 10 having a predetermined interval in the longitudinal direction of the vehicle body are installed in the space.

상기 충격흡수브래킷(10)은 상부는 좁고 하부는 그보다 넓게 벌어져 있는 형상으로, 상기 충격흡수브래킷(10)의 상부는 상기 펜더패널(3)의 끝단부와 연결설치된다. The shock absorbing bracket 10 has a narrow upper portion and a wider lower portion than the lower portion, and the upper portion of the shock absorbing bracket 10 is connected to an end of the fender panel 3.

또한, 상기 충격흡수브래킷(10)의 하부는 상기 펜더에이프런멤버(2)와 접촉된 상태로 차체 길이방향으로 벌어져 있는데, 상기 펜더에이프런멤버(2)와 접촉되는 상기 충격흡수브래킷(10)의 하부 일측(10a)은 펜더에이프런멤버(2)에 볼트체결이나 용접을 통해 고정설치되고, 상기 충격흡수부재의 하부 타측(10b)은 상기 펜더에이프런멤버(2)와 접촉되면서 슬라이딩 가능하되 소정의 탄성력을 갖도록 코일스프링과 같은 탄성부재(11)를 매개로 펜더에이프런멤버(2)에 탄성 설치되어 있다.In addition, the lower portion of the shock absorbing bracket 10 is opened in the vehicle body longitudinal direction in contact with the fender apron member 2, the lower portion of the shock absorbing bracket 10 in contact with the fender apron member 2. One side (10a) is fixed to the fender apron member (2) by bolting or welding, the other side of the lower (10b) of the shock absorbing member is in contact with the fender apron member (2) to slide a predetermined elastic force It is elastically installed on the fender apron member 2 via an elastic member 11 such as a coil spring to have.

상기 탄성부재(11)의 일측단은 펜더에이프런멤버(2)에 연결되고 타측단은 충격흡수브래킷(10)에 연결되어 상기 펜더패널(3)에 수직방향의 힘이 작용하여 상기 충격흡수브래킷(10)이 벌어질 때 탄성부재(11)의 장력을 극복하면서 벌어지도록 하여 상기 펜더패널(3)이 상기 펜더에이프런멤버(2)에 갑자기 부딪히는 것을 방지한다.One end of the elastic member 11 is connected to the fender apron member (2) and the other end is connected to the shock absorbing bracket (10) so that a force in the vertical direction acts on the fender panel (3). The fender panel 3 is prevented from suddenly hitting the fender apron member 2 by overcoming the tension of the elastic member 11 when 10) is opened.

즉, 상기 펜더패널(3)에 수직방향의 힘이 작용하면 펜더패널(3)이 하부 방향으로 눌리면서 1차 변형이 됨과 동시에 펜더패널(3) 하부의 충격흡수브래킷(10) 하부 양측이 벌어지면서 2차 충격흡수가 이루어지고, 그 다음에 상기 충격흡수브래킷(10) 하부의 일측에 설치된 탄성부재(11)가 탄성변형되면서 3차 충격흡수가 이루어진다.That is, when a force in the vertical direction acts on the fender panel 3, the fender panel 3 is pressed downward and becomes a primary deformation, and at the same time, both sides of the lower part of the impact absorption bracket 10 under the fender panel 3 are opened. Secondary shock absorption is made, and then the elastic member 11 installed on one side of the lower portion of the impact absorption bracket 10 is elastically deformed, and the third shock absorption is performed.

여기서, 상기 충격흡수브래킷(10)은 펜더패널(3)과 펜더에이프런멤버(2) 사이의 공간에 삽입 설치되며 차체 길이방향을 따라 일정한 간격으로 배치되나, 통상의 펜더패널(3)의 길이를 고려하면 약 3개정도 설치되는 것이 바람직하다. 따라서, 펜더패널(3)이 차체의 양측에 위치되므로 6개정도 필요하게 된다.Here, the shock absorbing bracket 10 is inserted into the space between the fender panel 3 and the fender apron member (2) and is arranged at regular intervals along the vehicle body length direction, the length of the conventional fender panel (3) In consideration, it is preferable to install about three. Therefore, since six fender panels 3 are located on both sides of the vehicle body, about six are required.

이상의 구성을 갖는 본 발명의 작용은 다음과 같다.The operation of the present invention having the above configuration is as follows.

도4a 및 도4b에 도시된 바와 같이 차량이 보행자와 정면 충돌하게 되면 보행자의 무릎부분이 차량의 전방범퍼에 부딪히면서 보행자는 후드패널(1)과 펜더패널(3)이 이루는 경계부위에 머리를 부딪히게 된다.As shown in FIGS. 4A and 4B, when the vehicle collides with the pedestrian in front of the vehicle, the knee of the pedestrian hits the front bumper of the vehicle and the pedestrian hits the head at the boundary formed by the hood panel 1 and the fender panel 3. Will be hit.

이때, 펜더패널(3)은 보행자 머리와 충돌되면서 찌그러짐과 동시에 그 하부에 있는 충격흡수브래킷(10)으로 충격에너지를 전달해 상기 충격흡수브래킷(10)의 하부가 벌어지게 된다. At this time, the fender panel 3 is crushed while colliding with the pedestrian head, and at the same time, the impact energy is transferred to the shock absorbing bracket 10 under the lower part of the shock absorbing bracket 10.

상기 충격흡수브래킷(10)의 일측은 펜더에이프런멤버(2)에 고정되어 있고 타측은 펜더에이프런멤버(2)상에서 슬라이딩 가능하게 탄성부재(11)에 의하여 탄설되어 있으므로 큰 외력이 가해지면 충격흡수브래킷(10)의 타측이 벌어지면서 상기 탄성부재(11)가 탄성변형하게 되는 것이다.One side of the shock absorbing bracket 10 is fixed to the fender apron member 2 and the other side is slidable on the fender apron member 2 by the elastic member 11 so that a large external force is applied to the shock absorbing bracket. As the other side of the (10) is opened, the elastic member 11 is elastically deformed.

따라서, 종래에는 보행자가 주로 머리를 부딪히는 펜더패널(3)의 끝단 부위가 펜더에이프런멤버(2)에 수직하게 연결되어 있어서 그 부위의 국부적 강도가 매우 높아 보행자 보호에 취약한 문제점이 있었는데, 본 발명에서는 그 부위에서의 충격흡수가 효율적으로 이루어지므로 보행자의 머리부위 상해치(HIC)가 낮아지는 장점이 있다.Therefore, in the related art, the end portion of the fender panel 3 in which the pedestrian hits the head mainly is vertically connected to the fender apron member 2, so that the local strength of the portion is very high, and thus there is a problem in that it is vulnerable to pedestrian protection. Since the shock absorption in the area is made efficiently, there is an advantage that the head injury (HIC) of the pedestrian is lowered.

실제로, 모형인체(dummy)로 펜더패널(3) 상부 끝단의 충돌해석을 실시한 결과 종래 구조에서는 HIC가 2667로 상당히 높은 반면, 본 발명의 구조에서는 HIC가 1237로 상해치가 50%이상 감소되었다.In fact, the impact analysis of the upper end of the fender panel 3 with a dummy body shows that the HIC is 2667 in the conventional structure, while the HIC is 1237 in the structure of the present invention, and the injury value is reduced by 50% or more.

상술한 바와 같이 본 발명에 따른 자동차용 펜더패널 마운팅부의 충격흡수구조에 의하면, 펜더패널과 펜더에이프런멤버 사이에 충격흡수브래킷이 설치되어 펜더패널로부터 입력되는 충격에너지를 흡수하므로 보행자 머리부위의 상해치가 현저히 저하되는 특유의 효과가 있다.As described above, according to the shock absorbing structure of the automobile fender panel mounting unit according to the present invention, a shock absorbing bracket is installed between the fender panel and the fender apron member to absorb the impact energy input from the fender panel, so that the injury value of the pedestrian head portion is increased. There is a distinctive effect that is significantly reduced.
