And because the support component 2 divides the first space 11 into a plurality of cavities in the outer panel 1, the doorsill profile 100 can maintain certain structural strength while ensuring a lightweight structure, and the plurality of cavities divided by the support member 2 gradually increases in cross-sectional area of each cavity in the first direction 12, it can be appreciated that the larger cross-sectional area of the cavity makes the sidewalls surrounding the cavity more susceptible to collapse and damage when compressed, therefore, by providing a plurality of cavities with different cross-sectional areas, the structural strength of the rocker section 100 in the first direction 12 can be gradually reduced, and the cavity with a large cross-sectional area has a certain collapsing and energy-absorbing effect, therefore, when the doorsill section bar 100 is extruded by collision, the large cavity part collapses and absorbs energy, and the structural strength of the small cavity part is high so as to keep the structural form of the doorsill section bar 100, thereby improving the collision resistance of the doorsill section bar 100.
