차량용 프론트 도어의 잠금노브레버 절환장치{Looking Knob Lever Change Prevention Apparatus of Front Door for Vehicles}Linging Knob Lever Change Prevention Apparatus of Front Door for Vehicles}

본 발명은 차량 프론트도어에 설치되어 이 프론트도어를 잠금 및 비잠금상태로 유지시키는 잠금노브레버에 관한 것으로, 상기 잠금노브레버가 외부충격에 의하여 잠금상태로 절환되는 것을 방지한 차량용 프론트도어의 잠금노브레버 절환방지장치에 관한 것이다.The present invention relates to a lock knob which is installed in a vehicle front door and keeps the front door in a locked and non-locked state, and locks the front door for a vehicle that prevents the lock knob from being switched to a locked state by an external impact. Knob lever switching prevention device.

최근 차량에는 운전자와 탑승객의 안전을 위하여 각종 안전장치가 설치되어 있으며, 이러한 안전장치중 충돌안전법규의 시험에 따르면 차량 충돌시 일정한 외부충격이 발생하여 충돌이 이루어진 다음 차량도어가 열리지 않는 상태를 유지하도록 되어 있으며 이 도어의 외부핸들 작동시에는 도어가 열리도록 규정되어 있다.Recently, various safety devices are installed in the vehicle for the safety of drivers and passengers. According to the test of the crash safety law, among the safety devices, a certain external shock occurs when the vehicle crashes and the vehicle door is not opened after the collision. The door is opened when the external handle of the door is operated.

한편 통상적인 차량의 도어래치의 경우 차량 정면충돌이 발생하게 되면, 일정치 이상의 충격하중이 가해져서 도어래치와 일련의 로드로 연결된 노브레버가 비잠금상태에서 잠금상태로 절환되는 일이 빈번하게 발생하는 바, 즉 이는 일정치 이상의 충격하중에 의하여 로드에 연결되는 벨크랭크가 전진하여 충돌후 차량의 외부에서 도어를 열지 못하게 되어 부상자 구조 등에 많은 애로사항으로 제기되어 왔다.On the other hand, in the case of a normal door latch of a vehicle, when a frontal collision occurs, a shock load of a certain value is applied, and a knob lever connected to a door latch and a series of rods frequently switches from a non-locked state to a locked state. That is, this has been raised as a lot of trouble for the structure of the injured, because the bell crank connected to the rod by the impact load of a certain value is advanced to prevent opening the door from the outside of the vehicle after the collision.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 차량 정면충돌시 잠금노브레버를 작동시키는 래치레버에 관성하중 상쇄력을 가하여 이 잠금노브레버가 비잠금상태에서 잠금상태로 절환되는 것을 방지함에 따라 충돌후 외부에서 도어를 열 수 있도록 이루어진 차량용 프론트도어의 잠금노브레버 절환방지장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, by applying an inertial load offset force to the latch lever for operating the lock lever lever in front of the vehicle, the lock knob is switched from the non-locked state to the locked state It is an object of the present invention to provide a lock knob switching prevention device of a front door for a vehicle configured to open a door from outside after a collision.

상기와 같은 목적을 달성하기 위한 본 발명은 도어의 바깥핸들과 로드를 통하여 연결된 래치의 베이스에 잠금노브레버를 작동시키기 위해 벨크랭크를 매개로일련의 연결로드들과 연결되는 래치레버가 설치되어 이루어진 잠금노브레버의 작동장치에 있어서, 상기 연결로드가 설치된 래치레버와 래치의 베이스 사이에는 이에 각각 형성된 연결구멍에 끼워져 장착되는 코일스프링이 탄지되어 있다.The present invention for achieving the above object is made of a latch lever is connected to a series of connecting rods via a bell crank to operate the lock knob in the base of the latch connected through the rod and the outer handle of the door In the operating device of the lock knob, a coil spring is inserted between the latch lever provided with the connecting rod and the base of the latch and fitted into the connection holes respectively formed therein.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명이 적용된 도어의 잠금노브레버를 작동시키는 전체 구성도이고, 도 2는 도 1의 A부 확대 구성도이다.1 is an overall configuration diagram for operating the lock knob of the door to which the present invention is applied, Figure 2 is an enlarged configuration view of a portion A of FIG.

본 발명은 도면에 도시된 바와 같이 도어(1)의 바깥핸들(2)과 로드(3)를 통하여 연결된 래치(4)의 베이스(5)에 잠금노브레버(6)를 작동시키기 위해 벨크랭크(7)를 매개로 일련의 상하부 연결로드(8a,8b)들과 연결되는 래치레버(9)가 설치되어 이루어진 도어의 잠금노브레버의 작동장치에 있어서, 상기 하부 연결로드(8b)가 설치된 래치레버(9)와 래치(4)의 베이스(5) 사이에는 이에 각각 형성된 연결구멍(10)들에 끼워져 장착되는 코일스프링(11)이 탄지되어 있다.According to the present invention, a bell crank (6) is operated to operate the lock knob (6) to the base (5) of the latch (4) connected through the rod (3) and the outer handle (2) of the door (1). 7) In the operating device of the lock lever lever of the door is provided with a latch lever 9 is connected to a series of upper and lower connecting rods (8a, 8b) via a latch lever provided with the lower connecting rod (8b) Between the 9 and the base 5 of the latch 4, the coil spring 11 fitted into the connection holes 10 formed therein is held.

즉 상기 래치(4)의 베이스(5)와 하부 연결로드(8b)가 연결된 래치레버(9) 사이에 코일스프링(11)이 탄지되어 있어서 충돌시 관성하중에 의하여 벨크랭크(7)가 화살표 방향으로 전진되는 것을 상쇄시키게 된다.In other words, the coil spring 11 is held between the base 5 of the latch 4 and the latch lever 9 to which the lower connection rod 8b is connected. To offset the advancement.

여기서 상기 탄지된 코일스프링(11)이 화살표 방향으로 작용하는 관성하중을 상쇄시키도록 되어 있다.Here, the fingered coil spring 11 is configured to cancel the inertial load acting in the direction of the arrow.

따라서, 차량의 정면충돌시 이 코일스프링(11)은 상기 벨크랭크(7)가 화살표 방향으로 전진되어 잠금노브레버(6)를 비잠금상태에서 잠금상태로 작동절환시키는 것을 방지하도록 되어 있다.Therefore, in the event of a frontal collision of the vehicle, the coil spring 11 is configured to prevent the bell crank 7 from moving forward in the direction of the arrow so that the lock knob 6 can be operated from the non-locked state to the locked state.

상기와 같이 본 발명에 따른 차량용 프론트도어의 잠금노브레버 절환장치는 차량의 정면충돌시 일정치 이상의 충격하중이 가해지더라도 이 충격관성하중을 상쇄시키는 코일스프링에 의해 이 잠금노브레버가 비잠금상태에서 잠금상태로 절환되지 않음에 따라 도어를 외부에서 개방시킬 수 있다.As described above, the lock knob lever switching device of the vehicle front door according to the present invention is unlocked by the coil spring which cancels the impact inertia load even if a shock load of a predetermined value or more is applied during the frontal collision of the vehicle. The door can be opened from the outside as it is not switched to the locked state.
