Description
본 발명은 차량의 백 도어 보강구조에 관한 것으로서, 상세하게는 백 도어의 내측패널의 형상을 변경하고, 외측패널과 내측패널 사이에 보강부재를 취부하여 차량의 후방충돌에 대하여 보다 향상된 내충격성을 갖게한 차량의 백 도어 보강구조에 관한 것이다.The present invention relates to a back door reinforcement structure of a vehicle, and more particularly, to change the shape of the inner panel of the back door, and install a reinforcing member between the outer panel and the inner panel to further improve impact resistance against rear collision of the vehicle. It relates to a back door reinforcement structure of a vehicle.
일반적으로 차량의 백 도어(Back Door)는 도 1에 도시한 바와 같이 주로 왜건(Wagon)차량 등 차량의 후미를 이루는 도어를 지칭한다.In general, the back door of the vehicle refers to a door that forms the rear of the vehicle, such as a wagon vehicle, as shown in FIG. 1.
이러한 백 도어가 장착된 차량은 추가적인 공간확보로 화물이나 사람을 더 싣기에 유리하다는 장점이 있으나, 후미에 트렁크가 구비된 통상의 승용차에 비하여 후방충돌력을 완충시키는 데에는 취약하다는 단점이 있다.Such a vehicle equipped with a back door has an advantage of loading more cargo or people by securing additional space, but has a disadvantage in that it is more vulnerable to buffering rear collision force than a conventional passenger car equipped with a trunk at the rear.
도 4는 종래 백 도어의 단면구조를 나타낸 것으로서, 외측패널(30 ; Outer Panel)과 내측패널(20 ; Inner Panel)의 단부가 상호 용접 결합된 구조로 되어있다. 도면에서 미설명부호 '40'은 글래스(Glass)이다.4 is a cross-sectional structure of a conventional back door, and an end of an outer panel 30 and an inner panel 20 are welded to each other. In the drawing, the reference numeral '40' is glass.
그러나 상기와 같은 종래 백 도어의 구조는 별다른 보강수단이 구비되지 않아 후방충돌 등의 충격이 가해질 때 매우 취약하여 차실내의 승객 안전성과 차체변형이 용이하다는 문제점이 있었다.However, the structure of the conventional back door as described above is not provided with a special reinforcing means is very weak when an impact such as a rear collision, there is a problem that the passenger safety in the cabin and the deformation of the vehicle body is easy.
본 발명은 상기한 종래 백 도어의 문제점을 감안하여 안출한 것으로서, 본 발명은 유사시 후방에서의 충돌 등에도 견딜 수 있도록 강성을 보강한 차량의 백 도어 보강구조를 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the conventional back door, and an object of the present invention is to provide a back door reinforcement structure of a vehicle reinforced with rigidity to withstand collisions in the rear in case of emergency.

상기한 목적을 이루기 위하여 본 발명은 차량의 후미에 설치되며 외측패널(30)과 내측패널(20)로 구성된 차량의 백 도어에 있어서,In order to achieve the above object, the present invention is installed in the rear of the vehicle and in the back door of the vehicle consisting of the outer panel 30 and the inner panel 20,
중앙부위를 수평방향 절곡하여 절곡부(21)를 형성한 내측패널(20);An inner panel 20 having the center portion horizontally bent to form a bent portion 21;
상기 내측패널(20)의 중앙 절곡부(21)에 밀착하여 지지하도록 내측으로 돌출된 중앙지지부(13)와, 상기 외측패널(30)의 내면에 밀착 지지되도록 외측으로 절곡시켜 접합면(11)(12)을 상하 각각 형성한 소정의 너비를 갖는 보강부재(10)를 취부시켜 구성되는 것을 특징으로 하는 차량의 백 도어 보강구조를 제공한다.A center surface 13 protruding inward to support the central bent portion 21 of the inner panel 20, and bent outward so as to be closely adhered to the inner surface of the outer panel 30. It provides a back door reinforcement structure of a vehicle, characterized in that the reinforcing member 10 having a predetermined width (12) is formed respectively.
이하 첨부된 예시도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 구조를 나타낸 분해사시도, 도 3은 본 발명의 단면구성도이다. 도시한 바와 같이 본 발명은 내측패널(20)의 중앙부를 외측으로 절곡하여 절곡부(21)를 돌출시킴으로써 보다 내충격성을 갖는 구조로 형성한다. 또한 상기 내측패널(20)과 외측패널(30) 사이의 공간부에는 도시한 바와 같은 보강부재(10)를 취부한다. 이러한 보강부재(10)는 상기 내측패널(20)의 중앙 절곡부(21)에 밀착하여 지지하도록 내측으로 돌출된 중앙지지부(13)와, 외측패널(30)의 내면에 밀착 지지되도록 외측으로 절곡시켜 접합면(11)(12)을 상하 각각 형성한 형태를 이룬다.2 is an exploded perspective view showing the structure of the present invention, Figure 3 is a cross-sectional configuration of the present invention. As shown, the present invention forms a structure having more impact resistance by bending the central portion of the inner panel 20 to the outside to protrude the bent portion 21. In addition, the reinforcing member 10 as shown in the space portion between the inner panel 20 and the outer panel 30 is mounted. The reinforcing member 10 is bent outward so as to be in close contact with the inner surface of the central support portion 13 and the outer panel 30 protruding inward to support the central bending portion 21 of the inner panel 20 in close contact. The upper and lower joining surfaces 11 and 12 are formed, respectively.
이러한 보강부재(10)는 도 2에 도시한 바와 같이 하나 이상의 개수를 취부하는 것이 바람직하며, 도면에서는 양쪽에 취부하여 2개를 설치한 것을 예시하였다.As shown in FIG. 2, the reinforcing member 10 is preferably mounted with one or more numbers. In the drawing, two reinforcement members are installed.
또한 별도로 도시하지 않았으나 차량의 후방충돌시 보다 충격흡수가 잘되도록 상기 보강부재(10)의 접합면(11)(12)과 외측패널(30)의 내면사이 접합부에는 구조용 충진제를 취부시키는 것이 바람직하다.In addition, although not shown separately, it is preferable to attach structural fillers to the joints between the joint surfaces 11 and 12 of the reinforcing member 10 and the inner surface of the outer panel 30 so as to absorb shocks better at the time of rear collision of the vehicle. .
이상과 같이 형성된 본 발명의 구조는 차량의 후방충돌시 외측패널(30) 쪽에서 충격이 가해질 때, 외측패널(30)의 내면을 지지하는 보강부재(10)의 상하 접합면(11)으로 충격이 전달되고 또한 보강부재(10)의 중앙지지부(13)를 통하여 내측패널(20)의 절곡부(21)로 전달되는 과정을 통해 충격이 상당량 흡수되게 된다.The structure of the present invention formed as described above, when the impact is applied from the outer panel 30 side during the rear collision of the vehicle, the impact to the upper and lower joint surface 11 of the reinforcing member 10 supporting the inner surface of the outer panel 30 The shock is also absorbed through the transfer process to the bent portion 21 of the inner panel 20 through the central support portion 13 of the reinforcing member 10.
이상과 같이 본 발명은 차량의 백 도어 보강구조에 관한 것으로서, 백 도어의 내측패널의 형상을 변경하고, 외측패널과 내측패널 사이에 보강부재를 취부하여 차량의 후방충돌에 대하여 보다 향상된 내충격성을 갖게 하므로 차실내의 승객의 안전성이 향상되고 차체변형을 억제하게 되는 효과가 있다.As described above, the present invention relates to a back door reinforcement structure of a vehicle, wherein the shape of the inner panel of the back door is changed, and a reinforcing member is mounted between the outer panel and the inner panel to further improve impact resistance against a rear collision of the vehicle. Since the safety of the passengers in the cabin is improved and the body deformation is suppressed.
