Description

자동차의 도어 침입 방지구조Door intrusion prevention structure of car

본 고안은 자동차의 도어 침입 방지구조에 관한 것으로서, 보다 상세하게는 측면충돌시 도어에 전달되는 충격을 순차적으로 흡수하여 도어가 손상되는 것을 최소할 수 있으며 동시에 도어가 승객룸으로 침입되는 최소화함으로써, 승객을 안전하게 보호할 수 있는 자동차의 도어 침입 방지구조에 관한 것이다.The present invention relates to a door intrusion prevention structure of a vehicle, and more particularly, by sequentially absorbing the shock transmitted to the door during side collision to minimize the damage to the door and at the same time by minimizing the intrusion into the passenger room, The present invention relates to a door intrusion prevention structure of a vehicle capable of safely protecting a passenger.

일반적으로 자동차 도어에 도어를 차체에 고정시키는 록킹장치가 구비되어 있고, 도어의 바깥측에는 록킹장치를 선택적으로 해제하여 도어를 열 수 있도록 하는 개방 손잡이가 설치됨과 동시에 도어의 내측에도 록킹장치를 선택적으로 해제하여 도어를 열 수 있도록 하는 도어 개방핸들이 구비된다. 또한 도어의 내측에는 도어를 여닫을 수 있는 개폐손잡이가 구비된다.In general, the door is provided with a locking device for fixing the door to the vehicle body, and on the outside of the door is provided with an opening handle to selectively open the door by selectively releasing the locking device, and at the same time the locking device on the inside of the door A door opening handle is provided to release the door by opening the door. In addition, the inside of the door is provided with an opening and closing handle that can open and close the door.

도어의 내측에는 측면충돌시 충격을 흡수하여 완화시키는 도어 임팩트 빔이 설치되어 있다. 도어 임팩트 빔은 측면충돌시 도어가 변형되며 승객룸측으로 밀려들어오는 것을 방지하여 승객의 안전을 도모하는 것으로서, 최근 자동차의 안전성을 향상시키고자 하는 노력이 기울여 지고 있는 현 실정을 감안할 때 안정성 향상에 매우 중요한 역할을 수행하고 있는 것이다.Inside the door is a door impact beam that absorbs and mitigates the impact during side impacts. The door impact beam is designed to improve the safety of passengers by preventing the door from being deformed and pushed into the passenger room in the event of a side collision. The current impact of improving the safety of automobiles is very significant in view of the current situation. It is playing an important role.

도 1은 종래기술에 따른 도어가 로커부에 밀착된 상태를 보인 측단면도이다. 도 1을 설명하면, 도어(10)는 외측패널(12)과 내측패널(14)로 구성되고, 외측패널(12)과 내측패널(14)의 사이에는 센터지지패널(16)이 고정된다. 내측패널(14)과 센터지지패널(16)의 사이에는 도어 글래스(미도시)가 수직방향으로 이동가능하게 설치된다. 센터지지패널(16)의 일측에 환봉으로 이루어진 도어 임팩트 빔(미도시)이 설치되고, 도어 임팩트 빔은 양단을 압착하거나 별도의 브라켓을 이용하여 센터지지패널(16)에 결합된다. 도어(10)의 내측패널(14) 하단은 사이드 바디인 로커부(22)에 밀착된다.1 is a side cross-sectional view showing a state in which the door according to the prior art is in close contact with the rocker unit. Referring to FIG. 1, the door 10 includes an outer panel 12 and an inner panel 14, and a center support panel 16 is fixed between the outer panel 12 and the inner panel 14. A door glass (not shown) is installed between the inner panel 14 and the center support panel 16 so as to be movable in the vertical direction. A door impact beam (not shown) made of a round bar is installed at one side of the center support panel 16, and the door impact beam is coupled to the center support panel 16 by pressing both ends or using a separate bracket. The lower end of the inner panel 14 of the door 10 is in close contact with the rocker portion 22 which is a side body.

상기와 같이 구성된 도어에 측면으로부터 충격이 전달되면 센터지지패널의 일측에 설치된 도어 임팩트 빔이 도어로 전달되는 충격을 흡수하지만, 도어 임팩트 빔이 설치되어 있지 않은 도어의 하단이 외부로부터의 충격시 침입(Intrusion)량이 크게 되어 도어가 손상됨은 물론 측면으로부터의 침입량이 많아지게 됨에 따라 승객을 안전하게 보호할 수 없는 문제가 있었다.When the shock is transmitted from the side to the door configured as described above, the door impact beam installed on one side of the center support panel absorbs the shock transmitted to the door, but the lower end of the door without the door impact beam is intruded upon impact from the outside. As the amount of intrusion increases, the door is not only damaged, but also the amount of intrusion from the side is increased, thereby preventing the passenger from being safely protected.

이에 본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로서, 그 목적은 측면충돌시 도어에 전달되는 충격을 순차적으로 흡수하여 도어가 손상되는 것을 최소할 수 있으며 동시에 도어가 승객룸으로 침입되는 최소화함으로써, 승객을 안전하게 보호할 수 있는 자동차의 도어 침입 방지구조를 제공함에 있다.The present invention is conceived in view of the above problems, the purpose of which is to minimize the damage to the door by sequentially absorbing the shock transmitted to the door in the event of a side collision and at the same time minimize the intrusion into the passenger room In addition, the present invention provides a vehicle door intrusion prevention structure that can safely protect passengers.

Referring to FIG. 2, the door 40 includes an outer panel 42 and an inner panel 44, and a center support panel 46 is fixed between the outer panel 42 and the inner panel 44. A door glass (not shown) is installed between the inner panel 44 and the center support panel 46 to be movable in the vertical direction. A door impact beam (not shown) made of a round bar is installed at one side of the center support panel 46, and the door impact beam is coupled to the center support panel 46 by pressing both ends or using a separate bracket. An incision groove 52 is formed at the bottom of the inner panel 44 of the door 40, and a reinforcement member 56 is fixed to the top of the rocker part 54 to restrict the door 40 from entering the passenger compartment. . This reinforcing member 56 is fixed to the upper end of the rocker portion 54 by spot welding. One side of the reinforcing member 56 is in close contact with one side wall of the incision groove 52, the impact beam 58 made of a round bar is inserted and fixed inside the reinforcing member 56.

상기와 같은 구성을 갖는 본 고안은 도어(40)에 측면으로부터 충격이 전달되면 센터지지패널(46)의 일측에 설치된 도어 임팩트 빔이 1차적으로 충격을 흡수하고, 로커부(54)의 상단에 스폿용접된 보강부재(56) 및 임팩트 빔(58)이 2차적으로 충격을 흡수함으로 도어(40)가 승객룸으로 침입되는 것을 최소화 할 수 있는 것이다. 즉, 도어(40)에 측면으로부터 충격이 전달되면 센터지지패널(46)의 일측에 설치된 도어 임팩트 빔이 1차적으로 충격을 흡수하고, 도어 임팩트 빔에서 흡수하고 남은 잔류충격에 의하여 도어(40)가 내측으로 침입된다. 이때 도어(40)의 하단에 형성된 절개홈(52)에 밀착된 보강부재(56) 및 임팩트 빔(58)이 잔류충격을 흡수함으로 도어(40)가 승객룸으로 침입되는 것을 최소화 할 수 있는 것이다. 이에 따라 충격에 의하여 도어(40)가 손상되는 것을 최소화 할 수 있으며 동시에 승객룸에 탑승한 승객을 안전하게 보호할 수 있는 것이다.According to the present invention having the configuration as described above, when the impact is transmitted from the side to the door 40, the door impact beam installed at one side of the center support panel 46 absorbs the impact primarily, and is located at the top of the rocker portion 54. The spot-welded reinforcing member 56 and the impact beam 58 is to minimize the entry of the door 40 to the passenger room by absorbing the secondary shock. That is, when an impact is transmitted from the side surface to the door 40, the door impact beam installed on one side of the center support panel 46 absorbs the shock primarily, and the door 40 is absorbed by the remaining impact after absorbing from the door impact beam. Intrudes inward. At this time, the reinforcing member 56 and the impact beam 58 in close contact with the incision groove 52 formed at the lower end of the door 40 absorb residual shock, thereby minimizing the intrusion of the door 40 into the passenger room. . Accordingly, damage to the door 40 may be minimized due to the impact, and at the same time, the passenger in the passenger room may be safely protected.

상술한 바와 같이 본 고안에 따른 자동차의 도어 침입 방지구조는 일측이 도어의 하단에 형성된 절개홈에 밀착되고, 내측에 임팩트 빔이 삽입고정된 보강부재가 로커부의 상단에 고정되어 있음으로 측면충돌시 도어가 손상되는 것을 최소화 할 수 있으며 동시에 승객룸에 탑승한 승객을 안전하게 보호할 수 있는 효과를 갖는 것이다.As described above, the door intrusion prevention structure of the vehicle according to the present invention is one side is in close contact with the incision groove formed in the lower end of the door, the reinforcing member inserted into the impact beam is fixed to the top of the rocker part when the side collision The damage to the door can be minimized, and at the same time, the passengers in the passenger compartment can be safely protected.
