Abstract

PURPOSE: A door of a vehicle having high rigidity structure is provided to minimize deformation in a broadside collision for safety of a passenger. CONSTITUTION: A door of a vehicle consists of an inner panel(12), an outer panel(11), a pair of horizontal impact bars(13,14), and vertical reinforce member(15). The inner panel and the outer panel are connected together with a closed part. The pair of the horizontal impact bars are installed according to the outer panel in the upper part and the lower part of the outer panel, and are fixed in the outer panel by brockets supporting both ends. The vertical reinforce member is installed to connect the upper impact bar and the lower impact bar. The upper part of the vertical reinforce member is fixed in the one side of the middle of the upper impact bar by welding, and the lower part of the reinforce member is fixed in the outer panel with the lower impact bar through a coupling bracket. The pair of the horizontal impact bars absorb outer force applied to the upper part and the lower part of the door and reduces when occurring the broadside collision. The outer force applied to the middle part of the horizontal impact bar is transferred to the pair of the horizontal impact bars through the vertical reinforce member and is dispersed.

Description

고강성 구조를 가지는 자동차의 도어{Door having a high stiffness in a motor vehicle}Door having a high rigidity structure {Door having a high stiffness in a motor vehicle}

본 발명은 승객의 안전을 위하여 측면 충돌시 변형이 최소화되도록 고강성 구조를 가지는 자동차의 도어에 관한 것이다.The present invention relates to a door of a vehicle having a high rigidity structure so that deformation is minimized during side impact for the safety of passengers.

자동차의 도어는, 도 1에 도시된 바와 같이, 자동차의 실내를 외부로부터 격리함과 동시에 운전자나 탑승객이 승하차할 수 있도록 실내를 개폐하기 위하여 자동차의 측부에 설치되어 있다.As shown in FIG. 1, the door of the vehicle is provided on the side of the vehicle to isolate the interior of the vehicle from the outside and to open and close the interior so that a driver or a passenger can get on and off.

이러한 자동차의 도어에 있어서, 운전자 또는 탑승객이 자동차 실내의 도어 바로 옆에 앉기 때문에, 측면 충돌시 도어가 변형되어 실내로 침입하면서 승객이 큰 상해를 입을 우려가 있다. 따라서, 자동차의 도어는 매우 높은 강성을 가질 것이 요구된다.In the door of such a vehicle, a driver or a passenger sits right next to the door of the vehicle interior, so that when the side collision occurs, the door may be deformed and the passenger may be injured seriously while breaking into the interior. Therefore, the door of the automobile is required to have a very high rigidity.

이를 위하여, 자동차의 도어는, 도 2에 도시된 바와 같이, 내, 외부 패널(1, 2)이 접합되어 형성되는 폐단면 내에 강성 보강을 위한 한 쌍의 임팩트 바(3, 4)가 설치되어 있다. 이 임팩트 바들(3, 4)은 브라켓(미도시)에 의해 도어 외부 패널(1)의 상부 및 하부에 각각 도어의 길이 방향을 따라 고정되어 있다. 도면에서, 미설명 부호 5는 도어 글래스다.To this end, the door of the vehicle, as shown in Figure 2, a pair of impact bars (3, 4) for stiffening reinforcement is installed in the closed end surface formed by the inner, outer panel (1, 2) is bonded have. These impact bars 3 and 4 are fixed to the upper and lower portions of the door outer panel 1 by brackets (not shown) along the longitudinal direction of the door, respectively. In the figure, reference numeral 5 denotes a door glass.

그러나, 상기와 같은 종래의 자동차 도어는 다음과 같은 단점이 있었다.However, such a conventional car door has the following disadvantages.

즉, 상기와 같은 종래의 자동차 도어는 외부 패널의 내면에 한 쌍의 임팩트 바가 고정됨으로써 측면 충돌에 대한 강성이 매우 향상되기는 했지만, 여전히 도어의 중앙부 즉, 임팩트 바들 사이로 가해지는 외력에 대한 강성이 취약하다는 단점이 있다. 이에 따라, 측면 충돌시 외력이 임팩트 바들의 중간 부분으로 집중될 경우 임팩트 바들의 중간에 대응되는 부분의 도어 패널이 과다하게 변형되어 자동차의 실내로 침입함으로써 탑승객의 신체에 상해를 입힐 수 있다.That is, in the conventional car door as described above, the rigidity against side collision is greatly improved by fixing a pair of impact bars on the inner surface of the outer panel, but the rigidity against the external force exerted between the center part of the door, that is, between the impact bars is still weak. The disadvantage is that. Accordingly, when the external force is concentrated in the middle of the impact bars during side impact, the door panel of the portion corresponding to the middle of the impact bars is excessively deformed and invades the interior of the vehicle, thereby injuring the passenger's body.

본 발명은, 상기와 같은 점을 감안하여 안출된 것으로, 도어 패널의 중앙부가 과다하게 변형되는 것을 방지하여 승객의 안전을 도모할 수 있도록 고강성 구조를 가지는 자동차의 도어를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object thereof is to provide a door of an automobile having a high rigidity structure to prevent the center portion of the door panel from being excessively deformed and to promote passenger safety. .

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 3 및 도 4는 본 발명의 일 실시예에 따른 자동차의 도어를 도시한다.3 and 4 illustrate a door of a vehicle according to an embodiment of the present invention.

도시된 바와 같이, 본 발명의 일 실시예에 따른 자동차의 도어는 내부 패널(12), 외부 패널(11), 한 쌍의 가로 임팩트 (13, 14), 및 세로 보강 부재(15)를 포함하고 있다.As shown, the door of an automobile according to an embodiment of the present invention includes an inner panel 12, an outer panel 11, a pair of transverse impacts 13, 14, and a longitudinal reinforcement member 15. have.

내부 패널(12)과 외부 패널(11)은 소정의 폐단면을 형성하도록 서로 접합되어 있다.The inner panel 12 and the outer panel 11 are joined to each other to form a predetermined closed cross section.

한 쌍의 가로 임팩트 바(13, 14)는 외부 패널(11)의 상부 및 하부에 각각 외부 패널(11)의 길이 방향을 따라 설치되어 있다. 이 임팩트 바들(13, 14)은 그 양단들을 지지하는 브라켓들에 의해 외부 패널(11)에 고정된다.A pair of horizontal impact bars 13 and 14 are provided in the upper part and the lower part of the outer panel 11 along the longitudinal direction of the outer panel 11, respectively. These impact bars 13, 14 are fixed to the outer panel 11 by brackets supporting both ends thereof.

세로 보강 부재(15)는 상부 임팩트 바(14)와 하부 임팩트 바(13)를 연결하도록 설치되어 있다. 이 세로 보강 부재(15)는 그 상단은 용접에 의해 상부 임팩트 바(14)의 중간 일측에 고정되고, 그 하단은 체결 브라켓(15a)을 통해 하부 임팩트 바(13)와 함께 외부 패널(11)에 고정되어 있다.The vertical reinforcing member 15 is provided to connect the upper impact bar 14 and the lower impact bar 13. The vertical reinforcing member 15 is fixed at the upper end to the middle one side of the upper impact bar 14 by welding, and the lower end thereof is connected to the outer panel 11 together with the lower impact bar 13 through the fastening bracket 15a. It is fixed at.

측면 충돌이 발생되면 한 쌍의 가로 임팩트 바(13, 14)가 도어의 상부 및 하부로 가해지는 외력을 흡수하여 저감시키며, 한 쌍의 가로 임팩트 바(13, 14)의 중간 부분으로 가해지는 외력은 세로 보강 부재(15)를 통해 한 쌍의 가로 임팩트 바(13, 14)로 전달되어 분산된다.When a side collision occurs, the pair of transverse impact bars 13 and 14 absorb and reduce the external force applied to the upper and lower portions of the door, and the external force applied to the middle portion of the pair of transverse impact bars 13 and 14. Is distributed through the longitudinal reinforcement member 15 to the pair of transverse impact bars 13, 14.

상기된 바와 같은 본 발명에 따른 자동차의 도어는, 한 쌍의 임팩트 바를 연결하는 세로 보강 부재가 설치되어 있기 때문에 한 쌍의 임팩트 바들의 중간 부분으로 가해지는 외력도 충분히 흡수 및 분산시켜 저감할 수 있다. 따라서, 도어의 강성이 매우 향상되어 운전자 또는 탑승객의 안전을 도모할 수 있는 장점이 있다.As described above, since the longitudinal reinforcing member connecting the pair of impact bars is installed in the door of the vehicle according to the present invention, the external force applied to the middle portion of the pair of impact bars can also be sufficiently absorbed and dispersed to reduce it. . Therefore, the rigidity of the door is greatly improved, and there is an advantage that can promote the safety of the driver or passengers.
