The invention relates to a new energy automobile doorsill stiffening beam which comprises a doorsill beam body which comprises a doorsill outer plate and a doorsill inner plate, and the doorsill outer plate and the doorsill inner plate are welded in a butt joint mode to define the doorsill beam body with a cavity inside. The doorsill stiffening beam is fixedly located in the cavity of the doorsill beam body and arranged close to the upper portion, and the Z-direction height of the doorsill stiffening beam in the cavity is flush with the seat cross beam and the rear floor front cross beam; the reinforcing beam support comprises a front supporting beam and a rear supporting frame which are located at the bottom of the doorsill reinforcing beam, and the front supporting beam is located on the front portion of the rear supporting frame and fixedly connected with the doorsill reinforcing beam and the doorsill beam body. The doorsill stiffening beam is supported in the Z direction through the front supporting beam and the rear supporting frame, the transverse sectional area of the doorsill stiffening beam is reduced while the side column collision performance and the front offset collision performance are met, the self weight of the doorsill stiffening beam is reduced, the lightweight design of a vehicle body is facilitated, and meanwhile the production cost is reduced.
本申请涉及一种新能源汽车门槛加强梁,包括:门槛梁本体,其包括门槛外板和门槛内板,门槛外板与门槛内板对合焊接围形成内部具有空腔的所述门槛梁本体;门槛加强梁,其固定位于门槛梁本体的空腔内并靠上设置,门槛加强梁在空腔内的Z向高度与座椅横梁和后地板前横梁齐平;加强梁支架,其包括位于所述门槛加强梁底部的前支撑梁和后支撑架,前支撑梁位于后支撑架的前部且均与门槛加强梁和门槛梁本体固定连接。本申请的门槛加强梁由前支撑梁和后支撑架进行Z向支撑,在满足侧面柱碰性能和正面偏置碰撞性能的同时缩少了门槛加强梁的横向截面积,减轻了门槛加强梁的自身重量,有利于车身轻量化设计,同时降低了生产成本。
