The invention relates to a threshold structure of an electric automobile, and belongs to the technical field of automobile design and manufacturing. The threshold structure of the electric automobilecomprises a threshold outer plate, a threshold inner plate and an aluminum threshold reinforcing beam. The threshold inner plate comprises a first vertical plane section making contact with a seat cross beam and a second vertical plane section corresponding to a power battery, an avoiding section is arranged between the first vertical plane section and the second vertical plane section, an effective collision space above the avoiding section is defined as an upper collision space, and an effective collision space below the avoiding section is defined as a lower collision space. The aluminum threshold reinforcing beam is located in the upper collision space, and a gap is formed between the rear end of the aluminum threshold reinforcing beam and the first vertical plane section of the threshold inner plate. When the threshold structure of the electric automobile is subjected to side collision, external loads can be effectively dispersed to the beam frame structure, collision energy can be effectively absorbed, the effective collision performance of the threshold cavity is guaranteed, and the arrangement space of a power battery is increased.
本发明涉及一种电动汽车门槛结构,属于汽车设计与制造的技术领域。本发明的电动汽车门槛结构包括门槛外板、门槛内板和铝门槛加强梁;门槛内板包括与座椅横梁接触的第一竖直平面段和与动力电池对应的第二竖直平面段,第一和第二竖直平面段之间设置有避让段,在避让段以上的有效碰撞空间定义为上部碰撞空间,在避让段下方的有效碰撞空间定义为下部碰撞空间,铝门槛加强梁位于上部碰撞空间内,铝门槛加强梁的后端与门槛内板的第一竖直平面段之间设置有间隙。本发明涉的电动汽车门槛结构侧碰时不仅可以有效的将外载荷分散到梁架结构上和吸收碰撞能量,保证了门槛腔体有效碰撞性能,并且还增加了动力电池的布置空间。
