B STIFFNESS REINFORCED STRUCTURE FOR B-PILLARLESS VEHICLE WITH OPPOSED SLIDING DOORS

摘要

The present invention, the column impact beam mounted vertically on one side of the door to support the door in the vertical direction of the vehicle; A center rail mounted horizontally in the center of the door to support the door in the front-rear direction of the vehicle and sliding the door; And a lower impact beam that is horizontally mounted on the lower portion of the door to support the door in the front-rear direction and forms an intersection point with a column impact beam at one end. do. According to the present invention having the configuration as described above, the column impact beam in the vertical direction is created on the door, thereby enhancing the collision stiffness and enhancing the ceiling strength when colliding with the side of the B-pillar facing sliding door. In addition, the present invention, there is an advantage that the center rail mounted on the door is not exposed to the outside when the door is opened and the productability is increased.
