Description
본 발명은 승용차의 후드를 보유지지하는 후드힌지구조에 관한 것으로, 더욱 상세하게는 보행자와 충돌시 이 보행자의 머리부분이 부딪히는 후드힌지부분의 충격에너지 흡수기능을 향상시키어 차량 안전기준을 만족시키는 승용차의 보행자 보호를 위한 충격 흡수용 후드힌지구조에 관한 것이다.The present invention relates to a hood hinge structure for holding a hood of a passenger car, and more particularly, a passenger car that satisfies the vehicle safety standards by improving the impact energy absorption function of the hood hinge portion where the head of the pedestrian collides when colliding with the pedestrian. It relates to a shock absorbing hood hinge structure for the protection of pedestrians.
일반적으로 승용차의 후드는 엔진룸을 덮고 있으면서 판넬펜더 에이프런(Panel-Fender Apron) 상부쪽에 설치되어 있는바, 따라서 이 후드는 이 판넬펜더 에이프론에 조립되는 힌지구조를 매개로 엔진룸의 개방을 위해 여닫을 수 있도록 되어 있다.In general, the hood of a passenger car covers the engine room and is installed on the upper side of the panel-fender apron. Therefore, the hood is used to open the engine room via a hinge structure assembled to the panel-fender apron. It is designed to open and close.
즉 종래 후드의 힌지구조는 이 후드의 지지력을 보강하기 위해 두께가 크고 고강성으로 구성되며, 도 3에 도시된 바와 같이 후드의 지지강성을 유지할 수 있는 큰 두께로 단절링크(111)구조를 갖추고 있다.That is, the hinge structure of the conventional hood has a large thickness and high rigidity to reinforce the supporting force of the hood, and as shown in FIG. 3, the break link 111 structure has a large thickness to maintain the support rigidity of the hood. have.
그러나 이와 같은 후드힌지구조는 보행자가 차량의 후드의 힌지부위에 부딪히게 되면, 고강도의 단절구조로 인하여 충돌시 변형공간이 없어 상당히 높은 보행자 머리부분의 상해치를 유발하게 되어 있다.However, such a hood hinge structure, when the pedestrian hits the hinge portion of the hood of the vehicle, due to the high-strength break structure there is no deformation space during the collision, causing a significantly higher injury value of the head of the pedestrian.
충돌시 이러한 보행자 두부 상해치가 큰 힌지구조는 차량의 안전기준을 강화시킨 최근 추세에 비추어 볼때 개선시킬 필요가 있었다.In the event of a collision, the hinge structure with high pedestrian head injury needs to be improved in light of recent trends that have strengthened vehicle safety standards.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 보행자 보호를 위해 후드를 보유지지하는 힌지구조에 충격흡수구조를 향상시키어 보행자와 충돌시 이 보행자의 두부 상해치를 저감시키어 안전성을 향상시킨 승용차의 보행자 보호를 위한 충격 흡수용 후드힌지구조를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above problems, improve the shock absorbing structure to the hinge structure holding the hood for pedestrian protection to reduce the head injury of the pedestrian when colliding with the pedestrian to improve safety It is an object of the present invention to provide a shock absorbing hood hinge structure for pedestrian protection of a passenger car.

상기와 같은 목적을 달성하기 위한 본 발명은 보행자의 두부가 후드의 힌지부위부분에 충돌하여 충격에너지가 일정하중의 이상치를 넘게 되면, 충격에너지를흡수하여 보행자의 두부 상해치를 저감시킬 수 있도록 카울 사이드 부재의 상부면에 장착되는 힌지조인축을 가진 후드 힌지구조에 있어서, 상기 힌지조인축은 행거를 매개로 힌지상부와 연결되고, 이 힌지조인축을 보유지지하는 힌지브라켓트들에는 힌지조인축이 슬라이딩 할수 있는 슬라이딩 안내구멍들이 상하방향으로 형성되어 있다.According to the present invention for achieving the above object, when the head of the pedestrian collides with the hinge portion of the hood and the impact energy exceeds the abnormal value of the constant load, the cowl side may absorb the impact energy to reduce the head injury of the pedestrian. In the hood hinge structure having a hinge joint shaft mounted on the upper surface of the member, the hinge joint shaft is connected to the hinge upper portion via a hanger, the hinge brackets holding the hinge joint shaft, the hinge joint shaft is slidable sliding Guide holes are formed in the vertical direction.
이하 본 발명은 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명이 카울사이드부재 위에 설치된 상태를 나타낸 설치상태도이고, 도 2는 도 1의 Ⅰ-Ⅰ선 단면도이다.1 is an installation state diagram showing a state in which the present invention is installed on the cowlside member, Figure 2 is a cross-sectional view taken along the line I-I of FIG.
본 발명은 카울사이드부재(1)의 상부면에 장착되어 후드를 보유지지하는 힌지조인축(2)을 가진 후드힌지구조에 있어서, 상기 힌지조인축(2)은 행거(3)을 매개로 힌지상부(4)와 연결되고, 이 힌지조인축(2)을 보유지지하는 힌지브라켓트(5)들에는 힌지조인축(2)이 슬라이딩 이동할 수 있도록 슬라이딩 안내구멍(6)들이 상하방향으로 형성되어 있다.The present invention is a hood hinge structure having a hinge joint shaft (2) mounted on the upper surface of the cowlside member (1) to hold a hood, wherein the hinge joint shaft (2) is hinged via a hanger (3) Sliding guide holes 6 are formed in the hinge brackets 5 which are connected to the upper part 4 and hold the hinge joint shaft 2 so that the hinge joint shaft 2 can slide. .
즉 본 발명은 후드힌지구조를 카울사이드부재(1)의 상부쪽에 힌지브라켓트(5)들이 보울트 또는 용접과 같은 체결수단으로 부착되고 이 힌지브라켓트(5)의 상부쪽 체결구멍(7)에 힌지조인축(2)이 끼워 장착된다.That is, according to the present invention, the hinge brackets 5 are attached to the upper side of the cowlside member 1 by fastening means such as bolts or welding, and hinged to the upper fastening holes 7 of the hinge brackets 5. The shaft 2 is fitted.
여기서 상기 힌지브라켓트(5)의 체결구멍(7)직경은 슬라이딩 안내구멍(6)의 폭(w)보다 더 크게 형성되어 있으면서 연속적으로 연통되어 있다.Here, the diameter of the fastening hole 7 of the hinge bracket 5 is continuously communicated while being formed larger than the width w of the sliding guide hole 6.
따라서 상기 힌지조인축(2)은 카울사이드부재(1) 상부에 설치된 힌지브라켓트(5)의 체결구멍(7)에 삽입되어 체결된 상태에서 외부의 충격, 예를 들어 보행자의 두부가 후두의 힌지 부위에 부딪혀 그 충격에너지가 일정치 이상이면 상기 힌지브라켓트(5)의 체결구멍(7)에서 이탈되어 슬라이딩 안내구멍(6)을 타고 이동 되어지면서 충격력을 완화시킨 구조로 되어 있다.Therefore, the hinge joint shaft (2) is inserted into the fastening hole (7) of the hinge bracket (5) installed on the cowlside member (1), and the external shock, for example, the head of the pedestrian is hinged on the larynx When the impact energy is more than a predetermined value by hitting the site, it is separated from the fastening hole 7 of the hinge bracket 5 and moved in the sliding guide hole 6, thereby reducing the impact force.
상기와 같이 본 발명에 따른 승용차의 보행자를 위한 충격흡수용 후드힌지구조는 후드를 보유지지하는 힌지구조가 일정치 이상의 충격에너지를 받게 되면 슬라이딩 이동되어 충격에너지를 완화시킴에 따라 보행자와 충돌 하였을때 이 보행자의 두부 상해치를 저감시키는 효과를 지닌다.As described above, the shock absorbing hood hinge structure for a pedestrian of a passenger car according to the present invention is slid when the hinge structure holding the hood receives a predetermined or higher impact energy, thereby colliding with the pedestrian as the shock energy is alleviated. This has the effect of reducing the head injury of pedestrians.
