The invention provides a threshold stiffening beam and a vehicle. The doorsill stiffening beam comprises a main beam body and a buffer body wrapping the outer portion of the main beam body. The buffering body is of a multi-cavity structure, and all cavities on the buffering body are densely arranged in the length direction and the height direction of the doorsill stiffening beam. According to the doorsill stiffening beam, by arranging the main beam body, a good basic framework can be formed, and the structural strength of the doorsill beam is improved; according to the doorsill stiffening beam, the buffering body of the multi-cavity structure is arranged outside the main beam body, the structural performance and the buffering performance of the doorsill stiffening beam can be effectively improved, the cavities are densely arranged in the length direction and the width direction of the doorsill stiffening beam, and when the doorsill stiffening beam is arranged in the inner cavity of the doorsill beam, the buffering performance of the doorsill stiffening beam can be effectively improved. Collision impact from the side portion of a vehicle can be effectively relieved due to collapsing deformation of the upper cavity of the buffering body, and therefore the structural performance and the buffering effect of the doorsill beam can be improved.
本发明提供了一种门槛加强梁及车辆。本发明的门槛加强梁包括主梁体,以及包覆于主梁体外部的缓冲体;缓冲体采用多腔结构,缓冲体上的各腔室在门槛加强梁的长度和高度方向上密集排布。本发明的门槛加强梁,通过设置主梁体,可形成良好的基础骨架,改善门槛梁的结构强度;在主梁体外部设置多腔结构的缓冲体,可有效提升门槛加强梁的结构性能和缓冲性能,在门槛加强梁的长度方向和宽度方向上密集排布地设置腔室,当将门槛加强梁布置到门槛梁的内腔中时,来自车辆侧部的碰撞冲击会因缓冲体上腔室的溃缩变形而有效缓解,从而利于改善门槛梁的结构性能和缓冲效果。
