The invention discloses a front seat rear cross beam assembly structure. The front seat rear cross beam assembly structure comprises two front seat rear cross beams which are symmetrically and separately arranged; a middle channel rear cross beam which is welded to the ends, close to each other, of the two front seat rear cross beams; and a front seat rear mounting plate welded at the other end of the front seat rear cross beam; wherein one end of the front seat rear mounting plate is welded and fixed with the front seat rear cross beams, and the other end of the front seat rear mounting plate forms a door frame inner plate connecting end; and a space between the middle channel rear cross beam and the front seat rear cross beam is configured as a middle channel cover plate mounting space. According to the front seat rear cross beam assembly structure, the closed section is formed by the front seat rear cross beam assembly structure and the doorsill inner plate in the Y direction, the front seat rear cross beam is used as a whole, structural stress is uniform, the stability is high, the welding is easy, the matching precision is high, and the structure has a great effect on improvement of local structural strength and vehicle body side collision.
本发明公开了一种前座椅后横梁总成结构,包括对称且彼此分离布置的两个前座椅后横梁;焊接于两个所述前座椅后横梁彼此靠近一端的中通道后横梁;以及焊接于所述前座椅后横梁另一端的前座椅后安装板;所述前座椅后安装板一端与所述前座椅后横梁焊接固定,所述前座椅后安装板另一端形成为门框内板连接端;所述中通道后横梁和所述前座椅后横梁之间的空间被配置为中通道盖板安装空间。本发明的前座椅后横梁总成结构在Y方向与门槛内板形成封闭截面,且前座椅后横梁作为整体,结构受力均匀,稳定性强,焊接简单,配合精度高,对局部结构强度以及车身侧碰提升具有很大的作用。
