[고안의 분야][Field of design]
본 고안은 자동차의 측면 충돌시 도어 변형 방지구조에 관한 것으로서, 보다 상세하게는 측면 충돌시 도어의 상측을 차체패널에 걸어주어 도어가 변형되는 것을 최소화하여 탑승자의 안전을 확보할 수 있도록 한 자동차의 측면 충돌시 도어 변형 방지구조에 관한 것이다.The present invention relates to a structure that prevents deformation of a door during a side collision of a vehicle, and more particularly, to secure the occupant's safety by minimizing the deformation of the door by hanging the upper side of the door to the body panel during a side collision. It relates to a door deformation prevention structure in the event of a side impact.
[종래기술][Private Technology]
일반적으로 자동차의 측면 충돌시 도어의 하측에 충격을 가하게 되는데, 이때 도어는 힌지부와 도어래치에 의해서만 차체와 고정이 이루어지게 되는바, 그의 고정력이 매우 미약하여 도어의 변형이 크게 발생된다.In general, the impact on the lower side of the door during the impact of the side of the car, the door is fixed to the vehicle body only by the hinge portion and the door latch bar, its fixing force is very weak, the deformation of the door is greatly generated.
즉, 자동차의 도어에 있어서, 그의 상측 정합부의 구성을 제5도를 보면서 살펴보면, 차체측(50)은 어퍼 및 로워 패널(51)(52)와 사이드 패널(53)의 접합으로 이루어지는 루프레일(54), 상기 루프레일(54)의 상측으로 접합되는 루프패널(55)로 형성되며, 도어 프레임(56)은 인너패널(57)과 아웃패널(58)의 접합에 의하여 형성되는 바, 도어의 상측에 대한 차체의 구속력이 전혀 없는 구조로 형성된다.That is, in the door of the automobile, looking at the configuration of the upper mating portion of the vehicle while looking at Fig. 5, the vehicle body side 50 is a roof rail consisting of the joining of the upper and lower panels 51, 52 and the side panel 53 ( 54, a roof panel 55 is joined to the upper side of the roof rail 54, the door frame 56 is formed by the joining of the inner panel 57 and the out panel 58, bar of the door It is formed in a structure without any restraint force on the upper body.
이에 따라 측면 충돌에 의하여 도어의 하측으로 충격이 가해지면 도어의 하측부분이 차실내측으로 밀려 변형되면서 그의 상측부가 외측으로 벌어지게 되어 도어의 변형을 가중시킴으로써, 탑승자의 안전을 위협하고, 이에 따른 인명피해가 뒤따르게 된다.Accordingly, when an impact is applied to the lower side of the door by a side collision, the lower part of the door is pushed into the interior of the vehicle and the upper part of the door is opened to the outside, thereby increasing the deformation of the door, thereby threatening the safety of the occupant. Damage follows.
[고안의 요지][Intention summary]
따라서 본 고안은 상기와 같은 종래 제반 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 측면 충돌시 도어의 상측을 차체패널에 걸어주어 도어가 변형되는 것을 최소화하여 탑승자의 안전을 확보할 수 있도록 한 자동차의 측면 충돌시 도어 변형 방지구조를 제공하려는 것이다.Therefore, the present invention is conceived to solve the above-mentioned conventional problems, the object of the present invention is to ensure the safety of the occupant by minimizing the deformation of the door by hanging the upper side of the door in the case of side collision It is to provide a door deformation prevention structure in the event of a side collision of a vehicle.
이를 실현하기 위하여 본 고안은 자동차의 도어 상측 정합부의 구조에 있어서, 상기 루프래널과 루프 사이드레일로 접합되는 드립레일의 자유단을 그의 접합면과 소정의 간격을 유지하도록 내측으로 절곡시켜 형성하고, 상기 도어 프레임의 인너패널의 내측면에 상단부에 외측으로 절곡되는 걸림편을 갖는 걸림부재를 배치하여 도어의 닫힘시 상기 걸림편이 드립레일의 자유단 하측에 근접되게 위치하도록 형성함을 특징으로 하는 자동차의 측면 충돌시 도어 변형 방지구조를 제공한다.In order to realize this, in the structure of the upper door matching portion of the vehicle, the free end of the drip rail joined by the roof rail and the roof side rail is formed by bending inward to maintain a predetermined distance from the joining surface, A vehicle having a locking member having a locking piece that is bent outwardly on an upper end portion of the inner panel of the door frame is disposed so that the locking piece is located near the lower side of the free end of the drip rail when the door is closed. It provides a door deformation prevention structure in case of side collision.
이하, 상기의 목적을 구체적으로 실현할 수 있는 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention capable of realizing the above object in detail as follows.
[실시예]EXAMPLE
제1도는 본 고안의 적용부위를 나타내기 위한 승용차의 사시도이고, 제2도는 제1도의 A-A선 단면도로서, 도어(1)의 상측 정합부 구성을 살펴보면 차체측(3)은 어퍼 및 로워 패널(5)(7)의 접합으로 이루어지는 루프 사이드레일(9)과, 상기 루프 사이드레일(9)의 상측으로 접합되는 루프패널(11)로 형성되며, 도어 프레임(13)은 인너패털(15)과 아웃패널(17)의 접합에 의하여 형성된다.FIG. 1 is a perspective view of a passenger car for showing an application part of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and when looking at the configuration of the upper mating portion of the door 1, the vehicle body side 3 is formed of an upper and a lower panel ( 5) and a roof side rail 9 formed by joining of 7 and a roof panel 11 joined to an upper side of the roof side rail 9, and the door frame 13 is formed of an inner pattern 15. It is formed by the joining of the outer panel 17.
상기와 같은 도어 상측 정합부의 구조에 있어서, 본 고안은 상기 루프패널(11)과 루프 사이드레일(9)로 접합되는 드립레일(19)의 자유단(21)을 그의 접합면(23)과 소정의 간격을 유지하도록 내측으로 절곡시켜 형성하였다.In the structure of the upper door matching portion as described above, the present invention is a free end 21 of the drip rail 19 to be bonded to the roof panel 11 and the roof side rail (9) by the joining surface 23 and the predetermined. It was formed by bending inward to maintain the interval of.
그리고 도어 프레임(13)의 인너패널(15)의 내측면에는 제3도에서와 같이 상단부에 외측으로 절곡되는 걸림편(25)을 갖는 걸림부재 (27)를 배치하여 도어의 닫힘시 상기 걸림편(25)이 드립레일(19)의 자유단(21) 하측에 근접되게 위치하도록 하였다.And on the inner surface of the inner panel 15 of the door frame 13 is disposed a locking member 27 having a locking piece 25 which is bent outward to the upper end as shown in Figure 3 when the locking piece when the door is closed (25) was positioned close to the lower end of the free end 21 of the drip rail (19).
이에 따라 측면 충돌로 인하여 도어(1)가 변형될 때에는 초기상태에서는 도어(1) 전체가 차내측으로 일단 밀렸다가 충돌부위는 게속 차내측으로 변형이 이루어지고 도어(1)의 상측은 외측으로 멀어지게 되는데, 이때 도어 프레임(13)의 인너패널(15) 내측에 상측으로 걸림편(25)이 형성된 걸림부재(27)를 배치하였는 바, 제4도에서와 같이 그의 상단 걸림편(25)이 드립레일(19)의 자유단(21)에 걸리게 된다.Accordingly, when the door 1 is deformed due to the side collision, the entire door 1 is pushed to the inside of the vehicle in the initial state, and then the collision part is deformed to the inside of the vehicle, and the upper side of the door 1 is moved away from the outside. At this time, the locking member 27 having the locking piece 25 formed therein is disposed inside the inner panel 15 of the door frame 13, and as shown in FIG. 4, the upper locking piece 25 is the drip rail. It is caught by the free end 21 of (19).
이와같이 걸림부재(27)의 걸림편(25)이 드립레일(19)의 자유단(21)에 걸리면 도어(1) 상측부가 외측으로 벌어지려는 것을 구속하게 되는 바, 도어 상측부의 변형을 최소화할 수 있는 것이다.As such, when the locking piece 25 of the locking member 27 is caught by the free end 21 of the drip rail 19, the upper part of the door 1 is restrained from spreading to the outside, thereby minimizing deformation of the upper part of the door. It can be.
즉, 도어 상측부의 변형력을 루프측으로 분산하여 루프측에서 수용토록함으로써, 변형을 줄일 수 있게 되는 것이다.In other words, the deformation force can be reduced by dispersing the deformation force of the upper part of the door to the roof side to accommodate the roof side.
상기와 같이 도어의 상측부 변형이 작아지면 도어의 충돌부의 이의 영향으로 적게 변형이 이루어지게 되어 이에 따른 탑승자의 안전을 확보할 수 있는 것이다.As described above, when the upper deformation of the door becomes smaller, less deformation is made due to the influence of the collision part of the door, thereby ensuring safety of the occupant.
