Description
본 고안은 자동차 프런트도어의 강성보강구조에 관한 것으로서, 더 상세하게는 자동차 프런트도어의 외측패널에 용착고정되는 보강벨트를 연장형성한후, 프런트패널과 프런트도어 내측패널에 용착된 코너브라켓의 소정부위에 연장된 부위를 용착시켜 내·외측패널을 상호 지지하고 프런트도어의 내구성 및 강성을 보강하도록 한 자동차 프런트도어의 강성보강구조에 관한 것이다.The present invention relates to a rigid reinforcing structure of an automobile front door, and more particularly, after extending a reinforcing belt welded to an outer panel of an automobile front door, a predetermined portion of a corner bracket welded to the inner panel of the front panel and the front door. The present invention relates to a rigid reinforcement structure of an automobile front door in which an extended portion is welded to each other to support the inner and outer panels and to reinforce the durability and rigidity of the front door.
일반적으로 자동차의 도어(Door)는 전방쪽에 설치되는 프런트도어와 후방쪽에 설치되는 리어도어로 구분되며 자동차의 좌·우 양측에 각각 설치되어 개폐되게 된다.In general, a door of a vehicle is divided into a front door installed at a front side and a rear door installed at a rear side, and installed at both left and right sides of the vehicle to be opened and closed.
본 고안은 특히 프런트도어에 관한 것이다.The present invention particularly relates to a front door.
이러한 자동차 프런트도어의 구조는 도 3에 도시된 바와같이 양단을 절곡하여 절곡부(3)를 형성한 외측패널(2)과, 상기 외측패널(2)의 절곡부(3)에 용착고정되는 용접부(6)가 일단에 형성되고, 상기 용접부(6)의 타단은 프런트도어(1)의 내측으로 절곡시킨 프런트패널(5)과, 상기 프런트패널(5)의 일측 소정부위에 일측이 용착고정되고 타단은 내측패널(4)과 글라스가이드(7)의 결합부 사이에 개재되어 용착고정되는 코너브라켓(8)과, 상기 외측패널(2)의 상부 내측면에 전후길이방향으로 용착고정되며 소정의 길이를 갖는 보강벨트(10)로 구성된다.The structure of the front door of the vehicle is as shown in FIG. 3, the outer panel 2 is bent at both ends to form the bent portion 3, and the welded portion welded to the bent portion 3 of the outer panel 2 (6) is formed at one end, and the other end of the welding portion (6) is welded and fixed to the front panel (5) bent inward of the front door (1), and one side of a predetermined portion of the front panel (5) The other end is interposed between the coupling portion of the inner panel 4 and the glass guide 7 and the corner bracket 8 is welded and fixed to the upper inner surface of the outer panel 2 and fixed in the front and rear length direction It is composed of a reinforcing belt 10 having a length.
이와같이 구성된 종래 자동차 프런트도어의 구조는 프런트도어(1)의 외측패널(2) 일단에 형성된 절곡부(3)에 프런트패널(5)의 용접부(6)를 용착고정시키되, 상기 프런트패널(5)의 타단은 코너브라켓(8)의 소정부위에 용착고정시킨다.The structure of the conventional front door of the vehicle configured as described above welds the welded portion 6 of the front panel 5 to the bent portion 3 formed at one end of the outer panel 2 of the front door 1, but the front panel 5 is fixed. The other end of is welded to a predetermined portion of the corner bracket (8).
이때 프런트패널(5)의 단부와 코너브라켓(8) 사이에는 프런트도어(1)의 내측패널(4) 일단부가 개재되어 용착되며, 상기 코너브라켓(8)의 일측단부에는 내측패널(4)의 소정부위가 용착고정된다. 상기 내측패널(4)과 코너브라켓(8)의 용접부위 내측면에는 글래스가이드(7)가 동시에 용착고정되며, 상기 외측패널(2)의 내측면에는 소정의 길이를 갖는 보강벨트(10)가 용착고정되어 프런트도어(1)의 내구성 및 강성을 보강하게 된다.In this case, one end of the inner panel 4 of the front door 1 is welded between the end of the front panel 5 and the corner bracket 8, and one side end of the corner bracket 8 is welded to the inner panel 4. A predetermined portion is welded and fixed. The glass guide 7 is welded and fixed to the inner surface of the welded portion of the inner panel 4 and the corner bracket 8 at the same time, and the reinforcing belt 10 having a predetermined length is formed on the inner surface of the outer panel 2. Welding is fixed to reinforce the durability and rigidity of the front door (1).
전술한 바와같은 자동차 프런트도어의 구조는 자동차 프런트도어 외측패널의 상부 내측면에 용착고정된 보강벨트가 외측패널 상부면에만 용착되어 있을뿐 프런트패널이나 내측패널 등에 연결되어 지지되는 부분이 없어 내구성 및 강성이 저하되게 된다.As described above, the structure of the front door of the automobile is a reinforcing belt welded to the upper inner surface of the outer panel of the automobile front door is welded only to the upper surface of the outer panel. Stiffness will fall.
그러므로 차량의 측면충돌시 도어에 충격이 가해지면 프런트도어를 보강하는 보강벨트가 이를 효과적으로 지탱하지 못해 도어가 쉽게 변형 및 파손되어 차체의 손상이 심각하게 발생할뿐아니라, 차실내의 승차자가 위험한 상황에 처하게 되는 등 안전성에 문제점이 있다.Therefore, when the impact is applied to the door during side impact of the vehicle, the reinforcing belt that reinforces the front door cannot effectively support it, and the door is easily deformed and damaged, causing serious damage to the vehicle body. There is a problem in safety, such as being placed.
따라서 본 고안의 목적은 자동차 프런트도어의 외측패널에 용착고정되는 보강벨트의 일측단을 연장형성한후, 연장된 부위를 프런트패널과 코너브라켓 및 내측패널의 용접부위에 용착지지되도록 하여 프런트도어의 내구성 및 강성을 보강하도록 한 자동차 프런트도어의 강성보강구조를 제공하는데 있다.Therefore, the object of the present invention is to extend the end of one side of the reinforcing belt welded to the outer panel of the front door of the car, and to weld the extended portion to the welded portion of the front panel, corner bracket and inner panel durability of the front door And to provide a rigid reinforcement structure of the vehicle front door to reinforce the rigidity.

Corner brackets 8 which are interposed between the coupling portions of the glass guide 7 and welded to each other, and reinforcement belts 10 which are welded and fixed in the front-rear length direction on the upper inner surface of the outer panel 2 and have a predetermined length. In the present invention, the front side of the reinforcing belt 10 welded to the upper inner surface of the outer panel (2) is bent to form an extended portion (11) welded to the inner predetermined portion of the corner bracket (8). It is to provide a rigid reinforcement structure of a car front door.
이하, 본 고안의 실시예를 첨부된 예시도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
도 2에 도시된 바와같이 외측패널(2)의 상부 내측면에 용착고정되는 보강벨트(10)는 전방쪽, 즉 프런트패널(5)쪽으로 연장형성하되, 연장부(11)는 프런트패널(5)과 내측패널(4)에 용착고정된 코너브라켓(8)과 밀착되도록 코너브라켓(8)에 대응되게 절곡시킨다.As shown in FIG. 2, the reinforcing belt 10 welded to the upper inner surface of the outer panel 2 extends toward the front side, that is, the front panel 5, but the extension part 11 is the front panel 5. ) And the corner bracket 8 is bent to correspond to the corner bracket 8 welded and fixed to the inner panel 4.
상기 보강벨트(10)의 연장부(11)와 외측패널(2)의 내측면에 용착된 부위는 대각선으로 절곡시킨다.The welded portion of the extension 11 of the reinforcing belt 10 and the inner surface of the outer panel 2 is bent diagonally.
상기와 같은 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above are as follows.
프런트도어(1)의 외측패널(2)에 형성된 절곡부(3)에 프런트패널(5)의 용접부(6)를 용착고정시키되, 상기 프런트패널(5)은 코너브라켓(8)과 내측패널(4)에 용착고정시킨다.The welded portion 6 of the front panel 5 is welded to the bent portion 3 formed on the outer panel 2 of the front door 1, wherein the front panel 5 includes a corner bracket 8 and an inner panel ( Weld and fix in 4).
이때 외측패널(2)에 용착고정된 보강벨트(10)의 일단을 연장하여 형성된 연장부(11)는 상기 코너브라켓(8)의 소정부위에 용착시켜 외측패널(2)이 프런트패널(5)과 코너브라켓(8) 그리고 내측패널(4)의 결합부위에 견고하게 지지되도록 한다.At this time, the extension part 11 formed by extending one end of the reinforcing belt 10 welded to the outer panel 2 is welded to a predetermined portion of the corner bracket 8 so that the outer panel 2 is the front panel 5. And it is to be firmly supported on the coupling portion of the corner bracket 8 and the inner panel (4).
상기와 같은 본 고안의 자동차 프런트도어의 강성보강구조는 외측패널에 용착고정된 보강벨트의 연장부가 프런트패널과 코너브라켓 그리고 내측패널에 견고하게 지지됨에 따라 프런트도어의 내구성 및 강성아 강화되어 차량의 충돌시 프런트도어에 가해진 외부충격을 보강벨트가 효과적으로 지지 및 지탱하여 외측패널이 내측패널쪽으로 밀리며 변형 및 파손되는 것을 최소로 줄일 수 있게 됨과 동시에 차실내의 승차자를 안전하게 보호하고 용접개소를 줄일 수 있어 작업성을 향상하고 작업공정의 단순화를 기대할 수 있는 효과가 있다.The rigid reinforcement structure of the vehicle front door of the present invention as described above, the extension of the reinforcing belt welded to the outer panel is firmly supported on the front panel, the corner bracket and the inner panel, so that the durability and rigidity of the front door is strengthened and the collision of the vehicle As the reinforcement belt effectively supports and supports the external shocks applied to the front door, the outer panel can be pushed toward the inner panel to minimize the deformation and damage, while also protecting the occupants in the cabin and reducing the welding spots. There is an effect that can be expected to improve the performance and simplify the work process.
