The invention discloses a collapse energy absorption box which comprises an upper bent plate, a lower bent plate and a reinforcing plate. One end of the reinforcing plate is connected with the upper bent plate, and the other end is connected with the lower bent plate. The invention further discloses a front wall support of an instrument board beam. The front wall support of the instrument board beam comprises the collapse energy absorption box, and the collapse energy absorption box and a front wall fixing support are made of different materials. The strength of the front wall fixing support is higher than that of the collapse energy absorption box. It can be guaranteed that when a vehicle collides in the forward direction, the collapse energy absorption box has the collapse energy absorption effect due to the low strength, the front wall fixing support cannot deform due to the high strength, and therefore the collapse energy absorption effect of the front wall support is improved, andmeanwhile the supporting rigidity of a direction pipe column is improved.

    本发明公开了一种溃缩吸能盒,其包括包括上弯折板、下弯折板和加强板;加强板的一端与上弯折板连接,另一端与下弯折板连接。本发明还公开了一种仪表板横梁的前围支架,所述仪表板横梁的前围支架包括上述溃缩吸能盒,溃缩吸能盒、前围固定支架采用不同材质制成;且前围固定支架的强度高于溃缩吸能盒。本发明能保证在车辆正向碰撞时,溃缩吸能盒由于强度较低,发生溃缩吸能作用,而前围固定支架由于强度高则不会产生变形,进而在提高了前围支架的溃缩吸能效果的同时,还提高了对方向管柱的支撑刚度。
