The invention relates to an automobile front stand column upper reinforcer structure which comprises a side-frame outer panel, an A column reinforcer, an A-pillar upper inner plate and an A-pillar upper reinforcer, and further comprises a rear connecting piece cooperatively connected with the rear section of the A-pillar upper reinforcer, wherein the A-pillar upper reinforcer is in a long-strip arc shape and arranged in the upper edge of an automobile side frame. The arc radius R of the front section and the middle section of the A-pillar upper reinforcer is greater than or equal to 600 mm; the cross section of the A-pillar upper reinforcer is in a closed cavity shape; one part of the front section of the A-pillar upper reinforcer is coated between the A-pillar reinforcer and the A-pillarupper inner plate, and the other part of the front section of the A-pillar upper reinforcer is coated between the side-frame outer panel and the A-pillar upper inner plate; the side-frame outer paneland the A-pillar upper inner plate are connected and fixed through a first welding spot and a second welding spot; and the A-pillar upper reinforcer and the A-pillar upper inner plate are connected and fixed through a third welding spot. On the premise that the cross-section size is not increased, the collision safety performance of the automobile offset collision can be improved, it is guaranteedthat the front-row member cabin does not deform, and the requirement for light weight is met.

    本发明涉及一种汽车前立柱上加强件结构,包括侧围外板、A柱加强件、A柱上内板和A柱上加强件,所述A柱上加强件呈长条弧形,设在汽车侧围的上边缘内,还包括与所述A柱上加强件后段配合连接的后连接件;所述A柱上加强件的前段与中段部位的圆弧半径R≧600mm;所述A柱上加强件的截面呈封闭空腔形;所述A柱上加强件前段的一部分被包覆在A柱加强件和A柱上内板之间、一部分被包覆在侧围外板和A柱上内板之间;所述侧围外板与A柱上内板通过第一焊点和第二焊点连接固定,所述A柱上加强件与A柱上内板通过第三焊点连接固定。本发明能够在不增加断面尺寸的前提下提升汽车偏置碰的碰撞安全性能,保证前排成员舱不变形,并满足轻量化的要求。
