Abstract

PURPOSE: A tail gate is provided to conveniently open and close the tail gate in a vehicle by controlling the motion of the tail gate employing a hydraulic cylinder and to minimize an area for opening and closing by foldably installing the tail gate. CONSTITUTION: A tail gate(30) is foldable via a joint and a hinge(40). Rollers(90) are combined to both sides of the tail gate to slide and rotate the tail gate by the operation of a hydraulic cylinder(110) and to open and close the tail gate. An opening button(10) and a closing button(20) installed at an area of a drivers seat apply power to an ECU(Electronic Control Unit)(80). An infrared sensor(70) detecting an obstacle inputs a sensing signal to the ECU to allow the ECU to output a control signal. A valve drive unit(65) directly controls a valve(60) of a hydraulic line to transmit hydraulic pressure generated from a hydraulic pump(50) to the hydraulic cylinder. According to transmission of the hydraulic pressure, the tail gate is opened and closed.

본 고안은 유압을 이용한 접힘식 테일 게이트에 관한 것으로서, 상세하게는 승합차의 리어 도어로 주로 사용되는 테일 게이트를 종래 여닫이 식에서 접힘식으로 설치함으로써 게이트의 개폐시 공간의 제한을 적게 하고 사용이 편리하게 한 유압을 이용한 접힘식 테일 게이트에 관한 것이다.The present invention relates to a folded tail gate using hydraulic pressure, and in detail, a tail gate, which is mainly used as a rear door of a van, can be folded in a conventional swing type to reduce the space limitation when opening and closing the gate, and to be convenient to use. A folding tail gate using a hydraulic pressure.

일반적으로 승합차와 같이 차체가 어느 정도 큰 차량은 리어도어를 갖게 되어 있으며 상기 리어도어는 일명 테일 게이트라 불리며 설치 및 사용되고, 또한 테일 게이트는 아래쪽에서 위쪽으로 손잡이에 의해 개폐될 수 있도록 설치/조작됨에 따라 게이트(도어) 개방시는 차량의 후측으로 게이트 개방에 필요한 일정 공간이 확보되어야 개폐가 가능할 수 있게 되어 있다.In general, a vehicle having a large body, such as a van, has a rear door, and the rear door is called a tail gate, which is installed and used, and the tail gate is installed / manipulated to be opened and closed by a handle from the bottom to the top. Accordingly, when opening the gate (door), opening and closing is possible only when a certain space necessary for opening the gate is secured to the rear side of the vehicle.

따라서, 차량의 높이가 큰 차량일수록 테일 게이트(도어)의 크기도 커짐에 따라 개폐에 필요한 공간도 많이 확보되어야 하며, 공간이 충분히 확보되지 않은 상태에서 자칫 테일 게이트(도어)를 개방할 경우에는 테일 게이트(도어)의 손상과 함께 접촉물체에 피해를 주는 경우를 겪게 된다.Therefore, the larger the vehicle height, the larger the size of the tail gate (door), the more space needed for opening and closing, and if the tail gate (door) is open when the space is not sufficiently secured In addition to damage to the gate (door), there is a case of damaging the contact object.

즉, 종래 테일 게이트는 개폐시 일정 공간이 확보되어야 개폐가 가능함에 따라 공간의 제한을 받게 되며 자칫 물체와의 접촉에 의해 테일 게이트의 손상과 접촉 물체에 피해를 주는 문제점이 있었다.That is, the conventional tail gate is limited in space as opening and closing is possible only when a predetermined space is secured during opening and closing, and there is a problem of damaging the tail gate and damaging the contact object by contact with an object.

이에, 본 고안은 상기한 바와 같은 문제점을 해소하기 위하여 안출한 것으로서, 종래 여닫이식 테일 게이트를 접힘식으로 설치하여 개폐에 필요한 제한 공간을 적게 하고 유압 실린더에 의해 제어되게 함으로써 차량의 실내에서도 스위치에 의해 개폐가 간편하게 조작될 수 있는 테일 게이트를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised to solve the problems as described above, by installing a conventional sliding tail gate in a folding manner to reduce the limited space required for opening and closing and to be controlled by a hydraulic cylinder to the switch even in the interior of the vehicle It is an object of the present invention to provide a tail gate which can be easily operated by opening and closing.
