The invention relates to the field of automobile manufacturing, and discloses a new energy automobile anti-collision threshold beam which comprises a front collision plate, the front collision plate is in a U shape, a supporting connecting plate is arranged on the inner side face of the front collision plate, and a longitudinal beam connecting plate is fixedly connected to one end of the side face of the front collision plate. A buffer layer connecting plate is welded to the side, away from the front collision plate, of the supporting connecting plate, a stress dispersion connecting plate is fixedly connected to the side, away from the supporting connecting plate, of the buffer layer connecting plate, and a battery protection soft plate is integrally and fixedly connected to the side, away from the buffer layer connecting plate, of the stress dispersion connecting plate. According to the anti-collision threshold beam of the new energy automobile, the impact resistance of the middle portion is enhanced, middle folding is avoided, and the battery module and passengers are protected; an efficient collision energy transfer path is constructed, and local stress is reduced; due to the design of a multi-layer anti-collision structure, the maintenance cost and the secondary accident risk are reduced.

    本发明涉及汽车制造领域,公开了一种新能源汽车防撞型门槛梁,包括正面碰撞板,正面碰撞板呈匚字形,正面碰撞板的内侧面设置有支撑连接板,正面碰撞板的侧面一端固定连接有纵梁连接板,支撑连接板远离正面碰撞板的一侧焊接连接有缓冲层连板,缓冲层连板远离支撑连接板的一侧固定连接有应力分散连板,应力分散连板远离缓冲层连板的一侧一体化固定连接有电池保护软板,应力分散连板的底部固定连接有底部吸能板,还包括缓冲层和应力分散承受装置,该新能源汽车防撞型门槛梁通过增强中部抗冲击能力,避免中折,保护电池模组和乘员;构建高效碰撞能量传递路径,减少局部受力;多层防撞结构设计,降低维修成本和二次事故风险。
