The present invention provides a dash cross member of a steel insert plastic, which is formed by injection-molding a steel insert including a main beam, a center support frame and the like with a plastic material and is formed in a form in which the steel insert and a plastic injection-molded part are combined, thereby enabling the reduction in weight of an electric vehicle, the improvement in electrical efficiency, and the increase in dynamic stiffness. The phenomena of damage and deformation caused by collision energy can be prevented, and the performance of isolating road surface vibration can be improved.

    本发明提供一种钢嵌件塑料的前围板横梁,其用塑料材料对包括主梁和中心支承架等的钢嵌件进行注塑成形,制作成钢嵌件与塑料注塑部结合的形态,从而能够实现电动车辆的轻量化且提高电效率,通过动刚度增大,能够防止因碰撞能量而损坏和变形的现象,并且能够提高对路面振动的隔绝性能。
