제2도는 제1도의 A-A선에 따른 단면도.2 is a cross-sectional view taken along the line A-A of FIG.

제3도는 본 발명에 관련하는 차량용 도어 인너 패널의 사시도.3 is a perspective view of a door inner panel for a vehicle according to the present invention.

제4도는 제1도의 A-A선에서 본 종래의 도어 패널의 구조를 도시한 단면도이다.4 is a cross-sectional view showing the structure of a conventional door panel seen from the line A-A of FIG.

[산업상의 이용분야][Industrial use]

본 발명은 차량용 도어 패널에 관한 것으로서, 보다 상세하게는 차량에 가해지는 측방충격을 흡수·완화시켜 승차자의 안전성을 향상시키는 차량용 도어 패널의 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door panel, and more particularly, to a structure of a vehicle door panel that absorbs and mitigates a side impact applied to a vehicle, thereby improving safety of a rider.

[종래 기술][Prior art]

일반적으로 차량용 도어 패널은 제4도에 도시된 바와 같이 차실의 내측으로 돌출된 형상으로 절곡된 인너패널(51)과 외측으로 돌출된 형상으로 절곡된 아웃패널(53)을 포함하여 구성된다.In general, the door panel for a vehicle includes an inner panel 51 bent in a shape projecting into the interior of the vehicle compartment and an out panel 53 bent in a shape projecting outward as shown in FIG. 4.

그리고 인너패널(51)과 아웃패널(53)의 양단이 중공부(55)를 형성하면서 상호 접합되며, 측방 충격력에 대항하여 충격력을 흡수·완화시켜 차실의 승객을 측방충격으로부터 보호하게 된다.And both ends of the inner panel 51 and the outer panel 53 are joined to each other while forming the hollow portion 55, and absorbs and alleviates the impact force against the side impact force to protect the passengers of the cabin from the side impact.

[본 발명이 해결하려는 문제점][Problem to solve by the present invention]

그러나 이러한 차량용 도어 패널의 구조는 충격이 가해지는 아웃패널과 승객과 근접하게 설치되는 인너패널과의 이격거리가 상당히 멀기 때문에, 측방충격을 충분히 흡수·완화시키지 못하고 도어 패널이 차실로 침입되어 승차자를 측방 충격으로부터 안전하게 보호하지 못한다.However, the structure of the door panel for the vehicle is far from the impacted out panel and the inner panel installed in close proximity to the passengers, so that the side panels do not sufficiently absorb and alleviate the side impacts, and the door panel is intruded into the cabin. No protection against side impacts.

따라서 본 발명은 상기와 같은 문제점을 해소하기 위하여 발명된 것으로서, 본 발명의 목적은 도어 패널에 가해지는 측방 충격력을 흡수·완화시켜 승차자의 안전성을 향상시키는 차량용 도어 패널의 구조를 제공하는 것이다.Therefore, the present invention has been invented to solve the above problems, and an object of the present invention is to provide a structure of a vehicle door panel that improves the safety of the occupant by absorbing and mitigating the side impact force applied to the door panel.

[문제점을 해소하기 위한 수단][Means to solve the problem]

이를 실현하기 위하여 본 발명에 따른 차량용 도어 패널의 구조는, 보디의 외측으로 돌출 절곡되어 제공되는 아웃패널과, 이 아웃패널의 내측에 중공부를 형성하면서 인너패널이 접합되는 구조로서, 상기 인너 패널은 아웃패널의 양단과 접합되며, 그 중앙부에 관통구를 형성한 제1인너패널과; 이 제1인너패널에 형성된 관통구를 차단하면서 제1인너패널의 외측에 접합되는 제2인너패널과; 상기 제1인너패널과 제2인너패널이 접합된 부분에 제공되어 그 일측은 제1패널의 외측에 접합되고 다른 일측은 제2 인너패널의 일측에 접합되는 보강패널;을 포함한다.In order to realize this, the structure of the door panel for a vehicle according to the present invention is an outer panel provided by protruding and bending to the outside of the body, and a structure in which the inner panel is joined while forming a hollow portion inside the outer panel. A first inner panel bonded to both ends of the out panel and having a through hole formed at a center thereof; A second inner panel joined to an outer side of the first inner panel while blocking the through hole formed in the first inner panel; And a reinforcement panel provided at a portion where the first inner panel and the second inner panel are joined to each other, one side of which is joined to the outside of the first panel, and the other side of which is joined to one side of the second inner panel.

상기 제2인너패널은 제1인너패널에 형성된 관통구를 완전히 차단할 수 있도록 관통구보다 크게 형성됨을 특징으로 한다.The second inner panel may be formed larger than the through hole so as to completely block the through hole formed in the first inner panel.

상기 보강패널은 제1인너패널과 제2인너패널이 접합된 양측에 각각 접합되는 방향으로 접합·제공됨을 특징으로 한다.The reinforcement panel is joined and provided in a direction in which the first inner panel and the second inner panel are joined to both sides to be joined, respectively.

상기 보강패널은 제1인너패널과 제2인너패널이 접합된 부분에 충격을 흡수할 수 있는 중공부를 형성하여 접합된다.The reinforcement panel is joined by forming a hollow portion capable of absorbing a shock in a portion where the first inner panel and the second inner panel are joined.

[작용][Action]

상술한 바와 같이 구성된 차량용 도어 패널의 구조는 제1인너패널에 제2인너패널을 접합시키고, 이와 같이 접합된 부분에 중공부를 갖는 보강패널을 접합시킴으로서, 측방에서 가해지는 충격력을 각각의 접합부분에서 흡수·완화케 함으로, 승차자에게 가해지는 충격력을 흡수·완화시킨다.The structure of the door panel for a vehicle configured as described above bonds the second inner panel to the first inner panel, and joins the reinforcement panel having the hollow portion to the joined portion, thereby applying the impact force applied from the side to each joining portion. By absorbing and relaxing, it absorbs and relaxes the impact force applied to the rider.

이하 본 발명의 바람직한 실시예를 첨부한 도면에 의하여 보다 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[실시예]EXAMPLE

제1도는 본 발명에 관련하는 부분을 설명하기 위한 차량 보디의 사시도로서, 도면 부호 1은 차실을 외부와 격리시켜 승차자를 보호하는 도어(1)이다.FIG. 1 is a perspective view of a vehicle body for explaining a part related to the present invention, wherein reference numeral 1 denotes a door 1 which isolates a vehicle compartment from the outside and protects a passenger.

이 도어(1)를 형성하는 도어 패널은 제2도에 도시된 바와 같이, 아웃패널(3)이 차량의 외측으로 돌출·절곡되고, 이 아웃팬널(3)의 내측으로 인너패널(5)이 제공되어 아웃패널(3)과 중공부(7)를 형성하면서 접합된다.As shown in Fig. 2, the door panel forming the door 1 has an outer panel 3 protruding and bending out of the vehicle, and the inner panel 5 is formed inside the outer panel 3. It is provided and joined while forming the outer panel 3 and the hollow part 7.

상기 인너패널(5)은 아웃패널(3)의 내측 양단과 접합되는 제1인너패널(9)과, 이 제1인너패널(9)에 접합되는 제2인너패널(11)을 포함한다.The inner panel 5 includes a first inner panel 9 bonded to both inner ends of the outer panel 3, and a second inner panel 11 bonded to the first inner panel 9.

그리고 제1인너패널(9)은 중앙부에 관통되어 충격을 흡수할 수 있는 관통구(13)를 형성하며, 제2인너패널(11)은 이 관통구(13)를 완전히 차단할 수 있는 크기로 제공되어 충격을 흡수하도록 제1인너패널(9)의 내측에 접합된다.In addition, the first inner panel 9 penetrates the center portion to form a through hole 13 to absorb shocks, and the second inner panel 11 is provided in a size capable of completely blocking the through hole 13. It is bonded to the inside of the first inner panel 9 to absorb the shock.

이와 같이 제1인너패널(9)과 제2인너패널(11)이 접합된 부분의 양측에 보강패널(15)이 내측으로 돌출되게 절곡되어 중공부(17)를 형성하면서 각각 접합되며, 보강패널(15)의 일측은 제1인너패널(9)의 일측에 접합되고, 다른 일측은 제2인너패널(11)의 일측에 접합된다.In this way, the reinforcement panel 15 is bent to protrude inwards on both sides of the portion where the first inner panel 9 and the second inner panel 11 are joined to each other, and are joined while forming the hollow portion 17. One side of 15 is joined to one side of the first inner panel 9, and the other side is joined to one side of the second inner panel 11.

그리고 이 보강패널(15)은 제2인너패널(11)이 제1인너패널(9)에 접합되는 방향과 같은 방향으로 제공된다. 본 실시예에서는 종방향으로 접합된 것을 예시한다.The reinforcement panel 15 is provided in the same direction as the direction in which the second inner panel 11 is joined to the first inner panel 9. In this embodiment, the bonding in the longitudinal direction is illustrated.

상술한 바와 같이 구성된 차량용 도어 패널의 구조에 측방 충격력이 가해지면, 아웃패널(3)의 양단에 접합된 제1인너패널(9)로 그 충격력이 전달된다.When the side impact force is applied to the structure of the vehicle door panel configured as described above, the impact force is transmitted to the first inner panel 9 bonded to both ends of the out panel 3.

이 충격력은 제1인너패널(9)과 제2인너패널(11)이 접합된 부분에서 1차적으로 감소되고, 제2인너패널(11)과 보강패널(15)이 접합된 부분에서 2차적으로 감소되며, 보강패널(15)과 제1인너패널(9)이 접합된 부분에서 3차적으로 감소된다.This impact force is primarily reduced at the portion where the first inner panel 9 and the second inner panel 11 are joined, and secondarily at the portion where the second inner panel 11 and the reinforcement panel 15 are joined. It is reduced, and is reduced in the third place at the portion where the reinforcement panel 15 and the first inner panel 9 are joined.

또한 상기 측방 충격력은 제1인너패널(9)에 형성된 관통구(13)와 보강패널(15)에 의하여 형성되는 중공부(17)에 의하여 상당부분 흡수·감소된다.In addition, the lateral impact force is substantially absorbed and reduced by the through hole 13 formed in the first inner panel 9 and the hollow portion 17 formed by the reinforcing panel 15.

[발명의 효과][Effects of the Invention]

상술한 바와 같이 본 발명에 따른 차량용 도어 패널의 구조는 제1인너패널의 관통구에 제2인너패널을 접합시키고, 이들 접합부에 중공부를 형성하는 보강패널을 접합시킴으로서, 측방 충격력을 1차, 2차, 3차에 걸쳐 흡수·완화시킴으로서, 최종적으로 승차자에게 작용하는 충격력을 감소시켜 승차자를 측방 충격으로부터 안전하게 보호할 수 있다.As described above, the vehicle door panel structure according to the present invention bonds the second inner panel to the through hole of the first inner panel, and joins the reinforcement panel forming the hollow part to the joining portion, thereby improving the lateral impact force. By absorbing and mitigating over the third and third stages, the impact force acting on the occupant is finally reduced, and the occupant can be protected from side impact.
