The invention relates to the technical field of automobile front hatch covers, and discloses an automobile front hatch cover inner plate structure and an automobile, the automobile front hatch cover inner plate structure comprises a front hatch cover middle structure at the middle position of an inner plate, and the front hatch cover middle structure forms a latticed structure through a plurality of cross beams and a plurality of vertical beams; cross concave arcs are arranged at the intersection points of the two ends of the first cross beam located in the middle and the vertical beams, cross ribs are arranged at the cross intersection points of the first cross beam and the vertical beams, and the cross ribs are located between the two cross concave arcs. Weight reduction weakening holes are formed in the positions, close to the two ends, of each vertical beam and the cross beams on the front side and the rear side of the first cross beam; the edge of the hollow part on the latticed structure forms a turnup; the steps of the middle structure of the front hatch cover are optimized, the cross ribs and the cross concave arc structures are arranged at the corresponding positions of the cross beams and the vertical beams to improve the concave resistance, the weight reduction weakening holes are formed on the basis, and finally balance between the pedestrian protection requirement and the concave resistance of the front hatch cover is achieved.
本发明涉及汽车前舱盖技术领域,公开了一种汽车前舱盖内板结构及汽车,包括内板中间位置的前舱盖中部结构,前舱盖中部结构通过若干横梁和若干竖梁形成网格状结构;位于中间位置的第一横梁两端与竖梁的交点处设置十字凹弧,第一横梁与竖梁的十字交叉点处设有十字筋,十字筋位于两十字凹弧之间;每一根竖梁靠近两端处以及第一横梁前后两侧的横梁上设有减重弱化孔;网格状结构上镂空部分的边缘形成翻边;本发明通过对前舱盖中部结构步骤进行优化,在横梁和竖梁的对应位置设置十字筋和十字凹弧结构提高抗凹性能,在此基础进行减重弱化孔的设置,最终实现了行人保护需求与前舱盖抗凹性能之间的平衡。
