상용차의 리어 데크의 사이드 게이트 휨 방지 구조{Device for preventing a bending of side gate of rear deck}Device for preventing a bending of side gate of rear deck}

본 발명은 상용차의 리어 데크의 사이드 게이트 휨 방지 구조에 관한 것이다.The present invention relates to a side gate bending prevention structure of the rear deck of a commercial vehicle.

기존의 상용차량인 트럭 적재함의 사이드 게이트는 고정 위치가 전후방의 2점 지지로 되어 있어 화물 적재시 사이드 게이트의 중앙부가 화물에 의해 변형되어 휨이 발생하는 경우가 있다.The side gate of the conventional truck loading box of the truck loading box is fixed to the front and rear two-point support, so that the center portion of the side gate is deformed by the cargo when the cargo is loaded, which may cause warpage.

본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여 사이드 게이트 중앙부에 보강철판을 설치하여 유압 실린더와 캐치부의 작동으로 바닥면 고정 프레임에 고정되어 사이드 게이트의 휨을 방지하는 휨 방지 구조를 제공하고자 하는 것이다.An object of the present invention is to provide a bending prevention structure that is fixed to the bottom fixed frame by the operation of the hydraulic cylinder and the catch portion by installing a reinforcing iron plate in the side gate center to solve the above problems. .

본 발명의 사이드 게이트의 휨 방지 구조는 사이드 게이트의 중앙부에는 보강 철판이 상하로 이동 가능하게 설치되고 보강 철판은 좌우측으로 돌출된 막대부를 가지며 하나의 막대부에는 유압 실린더가 연결되고 다른 막대부와 바닥면 사이에는 리턴 스프링이 설치되며 바닥면의 외측으로 고정 프레임이 설치되고 유압 실린더는 유압 호스에 의해 마스터 실린더에 연결되고 마스터 실린더는 적재함의 캐치부에 연동되어 작동되게 구성되어 사이드 게이트를 고정하기 위해서 캐치부가 눌러지면 마스터 실린더의 로드는 캐치부와 연동하여 마스터 실린더내의 유체를 밀어내고, 이때 발생된 유압은 유압 호스를 통해 유압 실린더를 작동시켜 보강 철판을 하방으로 이동시켜 보강 철판이 고정 프레임에 체결되게 구성된다.In the anti-bending structure of the side gate of the present invention, the reinforcing steel plate is installed at the center of the side gate so as to be movable up and down, and the reinforcing steel plate has a rod part protruding from the left and right sides, and one rod part is connected to a hydraulic cylinder, and the other rod part and the bottom part. A return spring is installed between the surfaces, and a fixed frame is installed outside the bottom surface, the hydraulic cylinder is connected to the master cylinder by a hydraulic hose, and the master cylinder is configured to operate in conjunction with the catch portion of the loading box to fix the side gate. When the catch is pressed, the rod of the master cylinder interlocks with the catch to push out the fluid in the master cylinder, and the generated hydraulic pressure actuates the hydraulic cylinder through the hydraulic hose to move the reinforcing steel plate downward so that the reinforcing steel plate is fastened to the fixed frame. It is configured to be.

본 발명을 첨부된 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도 1에는 본 발명의 사이드 게이트 휨 방지 구조가 도시되는데, 사이드 게이트(1)의 중앙부에는 보강 철판(2)이 상하로 이동 가능하게 설치된다.1 shows a side gate bending prevention structure of the present invention, wherein a reinforcing iron plate 2 is installed at a central portion of the side gate 1 so as to be movable up and down.

보강 철판(2)은 좌우측으로 돌출된 막대부(3)및(4)를 가지며 막대부(3)에는 유압 실린더(5)가 연결되고 막대부(4)와 바닥면(6)사이에는 리턴 스프링(7)이 설치된다.The reinforcing steel plate 2 has the rod parts 3 and 4 protruding to the left and right sides, the hydraulic part 5 is connected to the rod part 3, and the return spring is between the rod part 4 and the bottom surface 6. (7) is installed.

보강 철판(2)은 도시되지 않은 가이드에 의해서 사이드 게이트(1)의 외벽에 설치되며 보강 철판(2)의 하부에는 바닥면(6)의 외측으로 고정 프레임(8)이 설치된다.The reinforcing iron plate 2 is installed on the outer wall of the side gate 1 by a guide (not shown), and a fixing frame 8 is installed outside the bottom surface 6 at the lower part of the reinforcing iron plate 2.

따라서 도 2에 도시되듯이 보강 철판(2)이 하부로 내려오면 고정 프레임(8)에 삽입되어 사이드 게이트(1)를 지지한다.Therefore, as shown in FIG. 2, when the reinforcing iron plate 2 is lowered, the reinforcing iron plate 2 is inserted into the fixing frame 8 to support the side gate 1.

다시 도 1을 참조하면, 유압 실린더(5)는 유압 호스(9)에 의해 마스터 실린더(10)에 연결되고 마스터 실린더(10)는 적재함의 캐치부(11)에 연동되어 작동된다.Referring again to FIG. 1, the hydraulic cylinder 5 is connected to the master cylinder 10 by a hydraulic hose 9 and the master cylinder 10 is operated in conjunction with the catch portion 11 of the loading box.

캐치부(11)는 적재함의 측면에 부착되어 사이드 게이트(1)가 닫히면 사이드 게이트(1)를 고정시키는데 사용된다.The catch 11 is attached to the side of the loading box and is used to fix the side gate 1 when the side gate 1 is closed.

사이드 게이트(1)는 도 1에는 4개의 힌지(12)에 의해서 바닥면(6)에 고정되어 있다.The side gate 1 is fixed to the bottom surface 6 by four hinges 12 in FIG. 1.

본 발명의 사이드 게이트 휨 방지 구조의 작동을 설명한다.The operation of the side gate warpage prevention structure of the present invention will be described.

사이드 게이트(1)를 고정하기 위해서는 캐치부(11)를 누르게 되고 캐치부(11)가 눌러지면 마스터 실린더(10)의 로드(13)는 캐치부(11)와 연동하여 마스터 실린더(10)내의 유체를 밀어내고, 이때 발생된 유압은 유압 호스(9)를 통해 유압 실린더(5)를 작동시켜 보강 철판(2)을 하방으로 이동시켜 보강 철판(2)이 고정 프레임(8)에 체결된다.In order to fix the side gate 1, the catch portion 11 is pressed, and when the catch portion 11 is pressed, the rod 13 of the master cylinder 10 cooperates with the catch portion 11 in the master cylinder 10. The fluid is pushed out, and the generated hydraulic pressure actuates the hydraulic cylinder 5 through the hydraulic hose 9 to move the reinforcing steel plate 2 downward so that the reinforcing steel plate 2 is fastened to the fixed frame 8.

사이드 게이트(1)를 열 때는 상기와는 반대로 캐치부(11)를 당기게 되고 마스터 실린더(10)의 유압은 없어져서 보강 철판(2)은 리턴 스프링(7)에 의해서 상부로 이동하게 된다.When the side gate 1 is opened, the catch 11 is pulled opposite to the above and the hydraulic pressure of the master cylinder 10 is lost so that the reinforcing steel plate 2 is moved upward by the return spring 7.

따라서, 유체는 유압 실린더(5)로부터 마스터 실린더(10)로 되돌아간다.Thus, the fluid is returned from the hydraulic cylinder 5 to the master cylinder 10.

상기와 같이 구성된 본 발명의 사이드 게이트 휨 방지 구조는 캐치부를 누르면 유압이 형성되고 형성된 유압은 사이드 게이트에 있는 유압 실린더를 작동시켜 보강 철판을 하방으로 이동시켜 로킹되게 하고, 캐치부를 풀으면 유압이 형성되지 않아 보강 철판은 리턴 스프링에 의해 상부로 이동되어 언로크되어 화물 적재시 보강 철판은 고정 프레임에 끼워져 사이드 게이트의 중앙부의 변형을 방지할 수 있다.In the side gate bending prevention structure of the present invention configured as described above, the hydraulic pressure is formed by pressing the catch portion, the hydraulic pressure is formed by operating the hydraulic cylinder in the side gate to move the reinforcing steel plate downward to lock, the hydraulic pressure is formed when the catch portion is released Since the reinforcing steel plate is moved upward by the return spring and unlocked, the reinforcing steel plate is fitted to the fixed frame to prevent deformation of the central portion of the side gate when loading the cargo.
