The doorsill reinforcing part comprises a front section and a rear section, the front section is located between a column A and a column B, the rear section is arranged at the rear end of the column B, the wall thickness of at least part of the front section is larger than that of the rear section, and the outer contour and the structure of the front section are the same as those of the rear section. The section of the doorsill reinforcing piece is gradually increased from the outer side to the inner side. The invention further discloses the threshold. The doorsill reinforcer is divided into the front section and the rear section, the wall thickness of the front section is larger than that of the rear section, so that the front section is high in strength and can correspond to small offset collision and column collision, the thickness of the rear section is reduced, overall light weight can be achieved, and meanwhile side collision and light weight can be considered.

    本发明公开了一种门槛加强件,包括前段和后段,所述前段位于A柱与B柱之间,所述后段设置在所述B柱的后端,所述前段的至少部分壁厚大于所述后段的厚度,所述前段的外部轮廓和结构与所述后段的外部轮廓和结构相同,所述门槛加强件的断面从外侧向内侧逐渐增大。本发明还公开了一种门槛。本发明将门槛加强件分成了前段和后段,前段的壁厚大于后段的壁厚,使得前段的强度高,可对应小偏置碰撞和柱碰,后段的厚度减薄有利于实现整体的轻量化,同时能够兼顾侧碰和轻量化。
