The invention discloses a doorsill beam assembly which comprises a side wall outer plate, a side wall doorsill beam, a front floor doorsill beam, a doorsill lower longitudinal beam outer plate and a doorsill lower longitudinal beam inner plate. The side wall outer plate and the side wall threshold beam are fixed so that a first buffer cavity can be defined between the side wall outer plate and theside wall threshold beam. The front floor threshold beam and the side wall threshold beam are fixed to define a second buffer cavity between the front floor threshold beam and the side wall thresholdbeam, and the second buffer cavity is formed in the inner side of the first buffer cavity; the doorsill lower longitudinal beam outer plate and the doorsill lower longitudinal beam inner plate are fixed to define a third buffer cavity between the doorsill lower longitudinal beam outer plate and the doorsill lower longitudinal beam inner plate, and the third buffer cavity is formed in the inner side of the first buffer cavity and located on the rear side of the second buffer cavity. According to the doorsill beam assembly, by arranging the multi-stage energy absorption structure, the energy absorption capacity of the whole doorsill beam can be effectively increased, and then the collision safety of a vehicle is improved, so that the riding safety of passengers is guaranteed.
本发明公开了一种门槛梁组件,包括:侧围外板、侧围门槛梁、前地板门槛梁、门槛下纵梁外板和门槛下纵梁内板。侧围外板与侧围门槛梁固定以在侧围外板与侧围门槛梁之间限定出第一缓冲腔;前地板门槛梁与侧围门槛梁固定以在前地板门槛梁与侧围门槛梁之间限定出第二缓冲腔,第二缓冲腔设置在第一缓冲腔的内侧;门槛下纵梁外板与门槛下纵梁内板固定以在门槛下纵梁外板与门槛下纵梁内板之间限定出第三缓冲腔,第三缓冲腔设置在第一缓冲腔的内侧且位于第二缓冲腔的后侧。该门槛梁组件通过设置多级吸能结构,可有效增加整个门槛梁的吸能量,进而提升了车辆的碰撞安全性,以保证乘客的乘坐安全。
