Description

차량 도어의 충격흡수 보강멤버Shock-absorbing reinforcement member of vehicle door

본 발명은 차량 도어의 충격흡수 보강맴버에 관한 것으로서, 보다 상세하게는 맴버의 중앙부에 진공벽을 형성하고 상기 진공벽의 양측으로 실린더를 연결한 장치에 의해 도어 충돌시 상기 실린더의 작용에 의해 진공벽에 진공형성이 이루어져 충격흡수가 되도록 한 차량 도어의 충격흡수 보강맴버에 관한 것이다.The present invention relates to a shock absorbing reinforcing member of a vehicle door, and more particularly, by forming a vacuum wall in the center of the member and connecting the cylinders to both sides of the vacuum wall, by the action of the cylinder during door collision. The present invention relates to a shock absorbing reinforcing member of a vehicle door in which a vacuum is formed on a wall to absorb shock.

승용차의 도어는 일반적으로 외측의 아웃패널과 내측의 인너패널을 합쳐서 창유리를 둘러싼 틀(도어프레임)을 부착한 구조로 되어 있다.The door of a passenger car generally has a structure in which a frame (door frame) surrounding a window glass is attached by combining an outer panel of the outside and an inner panel of the inside.

이러한 도어는 상하 2개의 힌지에 의해 지지되며, 내외측으로 설치된 도어핸들에 의해 개폐되도록 되어 있다.These doors are supported by two hinges up and down, and are opened and closed by door handles installed inward and outward.

또한 도어는 프론트도어와 리어도어를 포함한다.The door also includes a front door and a rear door.

도어 외측의 핸들을 도어아웃사이드핸들이라고 하며, 도어 내측의 핸들을 도어인사이드핸들이라고 하며, 움직이는 방법에 따라 핸들 전체를 끌어 올리는 풀업식과 한쪽이 힌지로 되어 있는 풀라이즈식으로 분류된다.The handle on the outside of the door is called a door-outside handle, and the handle on the inside of the door is called a door-inside handle. The handle is classified into a pull-up type that pulls up the whole handle and a pulled type that has a hinge on one side.

또한 도어에는 주행중 도어개폐의 필요는 전혀 없으므로 도어를 폐쇄상태로 유지하기 위한 도어로크가 구성되는 데, 통상은 실내의 노브를 누르고 잠근상태로 함으로써 로크되지만, 리어도어와 같이 노브를 누른 채로 문을 닫았을 때 로크되는 것을 셀프로크, 프런트도어와 같이 실내노브를 누루고 문을 감그어도 셀프로크되지 않는 것을 셀프캔슬이라고 부르고 있다.In addition, there is no need to open or close the door during driving, and the door lock is configured to keep the door closed. Normally, the door is locked by pressing and locking the knob inside the room. Self-locking is called self-cancellation when the door is closed and the door is closed.

이러한 도어는 도어로크에 내장된 래치와 보디에 설치되어 있는 도어로크 스트라이커와의 작용에 의해 개폐작동이 이루어진다.These doors are opened and closed by the action of the door lock striker installed in the body and the latch embedded in the door lock.

도어의 개도는 약 60∼70도가 일반적이며, 이를 위해 도어를 반쯤 열린상태로 유지하며 더욱 열었을 때 스톱퍼의 역할을 하는 링크인 도어체크링크의 작용이 이루어진다.The opening degree of the door is generally about 60 to 70 degrees, and for this purpose, the door check link, which is a link that serves as a stopper when the door is held half open, is opened.

또한 도어에는 강성을 유지하며, 차량의 측면충돌시 그 충격흡수하여 승객을 보호하도록 된 보강맴버가 외측의 아웃터패널과 내측의 인너패널 사이에 설치된다.In addition, the door maintains rigidity, and a reinforcing member is provided between the outer outer panel and the inner inner panel to protect the passengers by absorbing the impact when the side impact of the vehicle.
