Description

화물 차량의 후부 안전가드{Safety guard of Truck}Safety guard of trucks

본 발명은 화물 차량의 후미부에 장착되어 외부 차량이 후방부에 충돌하였을 때 충돌 차량의 침입을 방지하여 차체와 탑승자를 보호하기 위한 후방 안전가드에 관한 것으로서, 보다 상세하게는 후방 안전가드를 알루미늄 재질로 제작하여 차체 후미부에 볼트를 매개로 하여 장착시킴으로써 차체 중량을 경량화 시키고, 차체 조립 공정에서 작업성을 향상시킬 수 있는 화물 차량의 후부 안전가드에 관한 것이다.The present invention relates to a rear safety guard for protecting the vehicle body and the occupant by preventing the intrusion of the collision vehicle when mounted to the rear portion of the cargo vehicle when the external vehicle collides with the rear portion, more specifically, the rear safety guard is aluminum The present invention relates to a rear safety guard of a freight vehicle, which is made of a material and mounted on the rear of the vehicle body via a bolt to reduce the weight of the vehicle body and improve workability in the vehicle assembly process.

일반적으로, 화물 차량의 후미부에는 외부와의 충돌 사고로 인해 발생되는 충격으로부터 차체와 탑승자를 보호할 뿐만 아니라 후방 차량과 탑승자를 보호할 수 있도록 함과 더불어 외관미를 향상시킬 수 있도록 하기 위하여 안전가드(self guarder)가 부착되는 데, 상기 안전가드는 통상적으로 스틸 재질로 제작되어 볼트와 같은 체결 수단을 매개로 하여 차체 프레임에 고정 설치된다.In general, the rear part of a cargo vehicle is not only to protect the body and the occupant from the impact caused by an external collision, but also to protect the rear vehicle and the occupant, and to improve the appearance beauty. A guard (self guarder) is attached, the safety guard is usually made of steel material is fixed to the vehicle body frame via a fastening means such as bolts.

도 1은 기존 화물 차량의 후미부에 안전가드가 장착된 모습을 도시하는 사시도이고, 도 2는 안전가드의 모습을 도시하는 사시도이며, 도 3은 도 2의 A-A 부분의 단면 모습을 도시하는 단면도이다.1 is a perspective view showing a state in which the safety guard is mounted to the rear portion of the existing freight vehicle, Figure 2 is a perspective view showing the state of the safety guard, Figure 3 is a cross-sectional view showing a cross-sectional view of the AA portion of FIG. to be.

상기 도면에 도시하였듯이, 차체 프레임(1)의 하부면에는 양측방향으로 나란하게 볼트를 매개로 하여 연결부재(2)가 장착되고, 상기 연결부재(2)의 단부에는 폭방향을 따라 사각형 모양의 단면 형상을 가지는 강관으로 형성된 안전가드(3)가 용접 등과 같은 접착수단을 통해 고정된다.As shown in the figure, the lower surface of the vehicle body frame (1) is mounted side by side in both directions via a bolt through the connecting member 2, the end of the connecting member (2) has a rectangular shape along the width direction The safety guard 3 formed of a steel pipe having a cross-sectional shape is fixed through an adhesive means such as welding.

상기와 같이 안전가드(3)가 장착되어 있는 화물 차량의 후미부에서 충돌 사고가 발생된 경우에 상기 안전가드(3)에 의해 일차로 충격이 흡수되고 동시에 이차로 연결부재(2)가 상부 또는 하부 방향으로 변형되면서 차체와 탑승자를 보호하게 되는 것이다.In the case where a collision accident occurs at the rear part of the cargo vehicle equipped with the safety guard 3 as described above, the shock is first absorbed by the safety guard 3 and at the same time, the connecting member 2 is at the top or the second. Deformed downwards to protect the body and occupants.
