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.
