THE CONNECTING STRUCTURE BETWEEN SIDESILL AND A FLOOR

摘要

The present invention relates to a side sill connection structure connected to both sides of the vehicle floor (floor), in order to improve the safety, the inner panel 21 and the outer panel 22 are coupled to the closed section When the side seal 20 is connected to the side end of the floor panel 10 forming the bottom portion of the vehicle, the lower end portion of the side seal is bent and the bent portion 23 is formed in which the upper portion is opened in the extension portion. The extension part is configured to be attached to the bottom surface of the floor panel to form a closed cross section, so that when the impact load is applied to the front or side of the vehicle, deformation of the floor panel 10 is effectively suppressed, so that the safety of the occupant is increased. The bottom structure of the floor panel 10 and the side chamber 20 is horizontally contacted to improve the sealing structure of the vehicle side chamber and the floor to facilitate the sealing operation of the contact portion.
