The invention discloses an A-pillar upper reinforcer with a non-uniform honeycomb inner core, a side wall assembly and a vehicle, the A-pillar upper reinforcer comprises a long-strip-arc-shaped A-pillar upper reinforcer body, a closed cavity extending in the length direction is formed in the A-pillar upper reinforcer body, the closed cavity is internally connected with the honeycomb inner core, and the honeycomb inner core is arranged in the closed cavity. The inner core comprises a plurality of hollow honeycomb units which are evenly arranged in an attached mode, the axis of each honeycomb unit is parallel to the axis of the closed cavity, the adjacent honeycomb units are coaxially arranged in the length direction of the closed cavity, and the lengths of the adjacent honeycomb units are different in the radial direction of the closed cavity. The rigidity of a vehicle body and the collision performance of the whole vehicle can be improved, the absorption frequency range is effectively widened, and the sound absorption performance of the A-column upper reinforcer under different wave bands is improved.
本发明公开了一种具有非均一蜂窝内芯的A柱上加强件、侧围总成及车辆,包括呈长条弧形的A柱上加强件本体,所述A柱上加强件本体内设有沿长度方向延伸的封闭空腔,所述封闭空腔内连接有呈蜂窝状的内芯,所述内芯包括多个均匀贴合排列的空心蜂窝单元,所述蜂窝单元的轴心线与封闭空腔的轴心线平行,在封闭空腔长度方向上,相邻蜂窝单元同轴布置,在封闭空腔径向方向上,相邻蜂窝单元的长度各不相同。其能够提升车身刚度和整车碰撞性能,有效拓宽吸引频率范围,提升A柱上加强件在不同波段下的吸音性能。
