It is.

먼저, 첨부도면 도 2는 본 발명의 바람직한 실시 예에 따른 구성을 나타낸 트럭 전방 측면 예시도이며, 첨부도면 도 3은 본 발명에 따른 안전범퍼(3)의 접힘 상태를 나타낸 측면 예시도로서 도면에서 도시한 바와 같이 트럭의 차체(1) 하부에는 지지부(2)를 형성하게 되는데 이 지지부(2)는 차체(1) 하부의 프레임과 일체가 되도록 볼트결합 또는 용접과 같은 방식으로 견고하게 형성하게 된다.First, the accompanying drawings, Figure 2 is a front view of the truck showing a configuration according to a preferred embodiment of the present invention, Figure 3 is a side view showing a folded state of the safety bumper 3 according to the present invention in the drawings As shown in the figure, a support part 2 is formed at the lower part of the vehicle body 1 of the truck, and the support part 2 is firmly formed in a bolted or welded manner so as to be integral with the frame under the vehicle body 1. .

한편, 트럭의 생산 과정에서 트럭에 설치되는 범퍼 하부에는 안전범퍼(3)를 설치하게 되는데 이 안전범퍼(3)는 트럭의 생산 과정에서 트럭에 설치되는 범퍼와 동일한 구조와 재질로 형성하는 것이 바람직할 것이다.Meanwhile, the safety bumper 3 is installed at the lower part of the bumper installed in the truck during the production of the truck. The safety bumper 3 is preferably formed of the same structure and material as the bumper installed in the truck during the production of the truck. something to do.

아울러, 안전범퍼(3)는 그 내측 형성된 회동부(301)를 상기 지지부(2)에 연결하여 회전 가능케 하며, 내측 하부에는 연결부(302)를 형성하게 된다.In addition, the safety bumper 3 is connected to the rotating part 301 formed on the inner side of the support part 2 to be rotatable, and to form a connection part 302 on the inner lower part.

그리하여 차체(1) 하부에 설치된 실린더(4)의 실린더로드(401)를 상기 연결부(302)에 연결하여 안전범퍼(3)를 회동시킬 수 있게 구성하게 된다.Thus, the cylinder rod 401 of the cylinder 4 installed under the vehicle body 1 is connected to the connecting portion 302 so that the safety bumper 3 can be rotated.

따라서 상기 실린더(4)는 안전범퍼(3)의 회동이 가능하도록 차체(1) 하부에 견고하게 설치하는 것이 바람직할 것이며, 실린더(4)의 견고한 설치 방법은 일반적인 실린더(4) 설치 방법과 같이 실린더(4)의 단부를 차체(1)에 볼트 결합하면 되기 때문에 실린더(4)의 설치에 관한 구체적인 설명은 생략한다.Therefore, the cylinder 4 should be installed firmly under the vehicle body 1 so that the safety bumper 3 can be rotated, and the rigid installation method of the cylinder 4 is the same as the general cylinder 4 installation method.
