The invention relates to the field of new energy vehicles, and discloses a doorsill assembly for a vehicle and the vehicle with the doorsill assembly. The doorsill assembly comprises an outer doorsilland an inner doorsill which are connected, and is characterized in that an accommodating cavity is formed between the outer doorsill and the inner doorsill; a rolling steel component is arranged in the accommodating cavity and connected to the inner side of the outer doorsill, and the rolling steel component is formed through a rolling die of a front bumper of the vehicle; and reinforcing piecesare arranged in the accommodating cavity and connected between the inner doorsill and the rolling steel component, and the multiple reinforcing pieces are arranged in the extending direction of the accommodating cavity at intervals. The vehicle comprises the doorsill assembly and further comprises a floor provided with a power battery pack, wherein the doorsill assembly is connected with the floor. The strength, rigidity, bending resistance and torsion resistance of the doorsill assembly are improved through the combination of the rolling steel component and the reinforcing pieces, lateral collision energy can be effectively absorbed, the safety of the power battery pack and the whole vehicle is improved, the rolling steel component is formed through the rolling die of the front bumper ofthe vehicle, a forming die of the rolling steel component does not need to be additionally arranged, and the forming process cost is low.
本发明涉及新能源汽车领域,公开一种用于车辆的门槛总成及具有该门槛总成的车辆。门槛总成包括相连的外门槛和内门槛,两者之间形成容纳腔;辊压钢构件设于容纳腔内并连接于外门槛的内侧,辊压钢构件使用车辆的前保的辊压模具成型;加强件设于容纳腔内并连接于内门槛和辊压钢构件之间,多个加强件沿容纳腔的延伸方向间隔设置。车辆包括上述的门槛总成,还包括安装有动力电池包的地板,门槛总成与地板连接。本发明通过辊压钢构件和加强件的组合提高门槛总成的强度、刚度、抗弯及抗扭转强度,能有效吸收侧向碰撞能量,提高动力电池包及整车安全性,辊压钢构件使用车辆的前保的辊压模具成型,无需额外增加辊压钢构件的成型模具,成型工艺成本低。
