Gangseongbo steel structure of front runnig tunnels

摘要

The present invention relates to a rigid frame steel structure for a front roof duct which is configured to absorb and support an impact from the outside in the event of a frontal collision of an automobile on the inner surface of a front roof tundal, The front roof tundal is configured to protect the vehicle body and passengers from shocks that are bent in a U-shaped shape when the vehicle is hit in a frontal collision. The front roof tundal includes a vertical surface having a predetermined width, And a reinforcing member formed by protruding a rectangular protrusion at the center of the vertical surface is integrally welded to the rear surface of the vehicle so that the rongy tunnels supporting the engine and the engine in the event of a frontal collision during operation are pushed to the passenger room, The effect is minimized.
