The invention discloses a vehicle doorsill beam structure coping with column collision. The vehicle doorsill beam structure comprises a side wall outer plate, a doorsill stiffening beam outer plate, a doorsill partition plate, a doorsill stiffening beam inner plate, a doorsill inner plate, a front floor, a side energy absorption box and a floor longitudinal beam. A doorsill inner plate is arranged on the inner side of the side wall outer plate, a doorsill partition plate is arranged between the side wall outer plate and the doorsill inner plate, a doorsill stiffening beam outer plate is arranged in an outer cavity formed by the doorsill partition plate and the side wall outer plate, and a first closed space is defined by the doorsill stiffening beam outer plate and the doorsill partition plate. The doorsill stiffening beam inner plate is arranged in an inner cavity formed by the doorsill partition plate and the doorsill inner plate, and a second closed space is defined by the doorsill stiffening beam inner plate and the doorsill partition plate. The front floor is connected to the inner side of the threshold inner plate, the floor longitudinal beam is arranged at the bottom of the front floor, and a side energy absorption box is arranged between the threshold inner plate and the floor longitudinal beam; according to the vehicle threshold beam structure coping with the column collision, energy absorption of side face column collision is facilitated, more energy can be absorbed, and local deformation is reduced.
本发明公开了一种应对柱碰的车辆门槛梁结构,包括侧围外板、门槛加强梁外板、门槛隔板、门槛加强梁内板、门槛内板、前地板、侧吸能盒和地板纵梁;侧围外板的内侧设置门槛内板,门槛隔板设置于侧围外板与门槛内板之间,门槛加强梁外板设置于门槛隔板与侧围外板构成的外腔体内,且门槛加强梁外板与门槛隔板围成封闭空间一,门槛加强梁内板设置于门槛隔板与门槛内板构成的内腔体内,且门槛加强梁内板与门槛隔板围成封闭空间二;前地板连接于门槛内板的内侧,地板纵梁设置于前地板的底部,门槛内板与地板纵梁之间设置有侧吸能盒;本发明中的应对柱碰的车辆门槛梁结构,有利于侧面柱碰的能量吸收,能够多吸收能量,减小局部的变形。
