Abstract

A structure of sensing an opened/closed state of a hood is provided to preclude a large space in an engine room from being excessively used by transmitting a transmission signal to an ECU(Electronic Control Unit) when a fixing part and a hinge pin are communicated. A hinge pin(30) of a hood hinge is installed between an inner panel of a hood and a vehicle body. Conductor regions and non-conductor regions are arranged to fixing parts(10a) of a hinge arm(10) respectively. The conductor regions and the non-conductor regions are contacted when the hood is closed respectively. The conductor regions are contacted when the hood is opened to transfer the transmission signal to the ECU(Electronic Control Unit). The fixing part is made of a conductive metal material, and each non-conductor region is coated with a non-conductive material.

3: 차체 4: 후드스위치3: Body 4: Hood switch

본 발명은 차량 후드의 개폐상태를 감지할 수 있도록 구성된 후드 개폐상태 감지구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hood opening / closing state detection structure configured to detect an open / closed state of a vehicle hood.

통상적으로 차량의 후드에 장착되는 도난경보장치는, 도1에 도시된 바와 같이, 후드(1)가 닫힐 때 후드(1)의 인너패널에 장착된 패드(2)가 차체(3)의 펜더에이프런부에 장착된 후드스위치(4)를 누르는 것에 후드의 개폐상태를 감지하고, 그 신호를 중앙제어부(ECU)에 송출하여 경고음을 발생시키도록 구성된다.1, a pad 2 mounted on an inner panel of a hood 1 is attached to a fender apron of a vehicle body 3 when the hood 1 is closed, Detects the open / close state of the hood by pressing the hood switch (4) mounted on the hood, and sends the signal to the central control unit (ECU) to generate a warning sound.

그러나, 이러한 종래의 후드 개폐상태 감지구조는 다음과 같은 문제점이 있다.However, the conventional hood opening / closing state detection structure has the following problems.

즉, 후드와 차체에 별도로 패드(2), 스위치(4) 등의 부품을 설치하여야 하므로 엔진룸 내에 배치되는 다른 부품의 레이아웃 구성에 제약을 주는 문제가 있다.In other words, since the components such as the pad 2 and the switch 4 must be separately provided in the hood and the vehicle body, there is a problem that the layout configuration of other components disposed in the engine room is restricted.

또한, 차량이 노후되는 경우, 패드(2)가 이탈하여 스위치 작동이 제대로 이루어지지 않는 문제점이 있다.Further, when the vehicle is aged, the pad 2 is disengaged and the switch operation is not properly performed.

한편, 위와 같은 문제점의 해결을 위해, 후드랫치에 전자식 스위치를 설치하는 경우도 있으나, 먼지의 유입에 의해 작동에 문제가 발생될 수 있으며, 특히 원가부담이 크다는 문제점이 있다.In order to solve the above problems, there is a case where an electronic switch is provided on the hood latch. However, there is a problem that the operation may be caused by inflow of dust, and the cost burden is particularly large.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것으로, 별도로 엔진룸 내 공간을 소비하지 않으며, 간단한 구조를 갖는 비용경제적인 후드 개폐상태 감지구조를 제공함을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a cost-effective hood open / closed state sensing structure that does not require a space in an engine room and has a simple structure.

상기의 목적을 달성하기 위한 본 발명에 따른 후드 개폐상태 감지구조는, 후드의 인너패널과 차체 사이에 설치된 후드힌지의 힌지핀과 이 힌지핀에 결합되어 회동하는 힌지아암의 고정부에 각각 도체 영역 및 부도체 영역이 마련되며, 후드가 닫힌 상태에서는 각각의 도체 영역과 부도체 영역이 서로 접촉되며, 후드가 열린 상태에서는 각각의 도체 영역과 도체 영역이 서로 접촉되어 그 통전신호가 중앙제어부로 전달되도록 한 것을 특징으로 한다.According to an aspect of the present invention, there is provided a hood opening / closing state detecting structure, including a hinge pin of a hood hinge disposed between an inner panel of a hood and a hinge pin of a hood, And the conductor region and the non-conductor region are in contact with each other when the hood is closed, and when the hood is opened, the conductor regions and the conductor region are brought into contact with each other and the energization signal is transmitted to the central control unit .

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 후드 개폐상태 감지구조에 대하여 살펴본다.Hereinafter, a hood opening / closing state detection structure according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

도2 및 도4은 후드의 개폐작동에 따른 후드힌지 상태를 도시한 도면으로, 후드가 닫힌 상태(도2 참조)일 때, 힌지핀(30)에 고정부(10a)가 회동가능하게 결합된 힌지아암(10)은 하방향 내려와 접혀져 있는 상태가 되며, 후드가 열린 상태(도4 참조)일 때, 힌지아암(10)은 상방향 회동된다. 이때, 힌지핀(30)은 힌지브라켓(20)에 견고히 고정되어 있으며, 힌지아암의 고정부(10a)는 후드의 개폐각에 따라 회동되면서 힌지핀(30)과의 위상차를 발생시킨다.2 and 4 are views showing the hood hinge state according to the opening and closing operation of the hood. In the hood 30 (see Fig. 2), when the hinge pin 30 is pivotally connected to the hinge pin 10 The hinge arm 10 is lowered and folded, and when the hood is opened (see Fig. 4), the hinge arm 10 is rotated upward. At this time, the hinge pin 30 is firmly fixed to the hinge bracket 20, and the fixed portion 10a of the hinge arm is rotated according to the opening / closing angle of the hood to generate a phase difference with the hinge pin 30.

본 발명은 이러한 후드힌지의 작동구조를 이용한 것으로, 도3 및 도5에 도시된 바와 같이, 후드 개폐상태 감지구조는 힌지핀(30)과 힌지아암(10)의 고정부(10a)에 각각 도체 영역(31,12) 및 부도체 영역(32,11)이 마련되어, 필요에 따라 힌지핀(30)과 힌지아암(10)이 서로 통전될 수 있도록 구성된다.3 and 5, the hood opening / closing state detection structure includes a hinge pin 30 and a fixed portion 10a of the hinge arm 10, Regions 31 and 12 and nonconductive regions 32 and 11 are provided so that the hinge pin 30 and the hinge arm 10 can be energized with each other as required.

후드힌지는 통상적으로 전도성의 금속재질로 제작되는 바, 힌지아암(10)의 고정부(10a) 일부에 부전도성 물질을 코팅(부도체 영역)(11)하고, 이 고정부(10a)와 접촉되는 부위의 힌지핀(30)에는 거의 전체 걸쳐 부전도성 물질을 코팅(부도체 영역)(32)하고 일부에만 도체 영역(31)을 남겨둔다. 물론, 이와 반대로 설계하는 것도 가능하다.The hood hinge is typically made of a conductive metal material and is formed by coating a portion of the fixed portion 10a of the hinge arm 10 with a nonconductive material 11 and contacting the fixed portion 10a (Non-conductive region) 32 and almost all of the conductive region 31 is left in the hinge pin 30 of the region. Of course, it is also possible to design the other way around.

위와 같은 후드 개폐상태 감지구조의 작동을 살펴보면, 후드(1)가 닫힌 상태에서는 고정부(10a)의 부도체 영역(11)이 힌지핀(30)의 도체 영역(31)에 접촉(도3 참조)되며, 후드(1)가 열린 상태에서는 힌지아암(10)이 회동되어 고정부(10a)의 도체 영역(12)이 힌지핀(30)의 도체 영역(31)에 접촉되며, 이에 따라 통전된다.When the hood 1 is closed, the non-conductive region 11 of the fixing portion 10a contacts the conductor region 31 of the hinge pin 30 (see FIG. 3) The hinge arm 10 is rotated so that the conductor region 12 of the fixed portion 10a contacts the conductor region 31 of the hinge pin 30 and is energized accordingly.

한편, 고정부(10a)와 힌지핀(30)에는 서로가 통전되었을 때 그 통전신호가 중앙제어부(ECU)로 전달되도록, 기존의 전기회로에 연결될 필요가 있다. 그 연결은 통상의 공지기술에 따른다.On the other hand, the fixing portion 10a and the hinge pin 30 need to be connected to a conventional electric circuit so that the energizing signal is transmitted to the central control unit (ECU) when they are energized with each other. The connection is in accordance with conventional techniques.

상술한 바와 같은 구조로 이루어진 후드 개폐상태 감지구조는, 별도로 엔진룸 내 공간을 소비하지 않으며, 비용경제적이며 간단하다.The hood opening / closing state detection structure having the above-described structure does not require any space in the engine room, and is economical and simple.
