The invention relates to a reinforcer structure of an automobile rear longitudinal beam assembly. Comprising two rear longitudinal beams and a cross beam, the two ends of the cross beam are fixedly installed on the two rear longitudinal beams respectively, a plurality of reinforcing plates are fixedly installed on the rear longitudinal beams and located between the ends of the rear longitudinal beams and the cross beam, and first through holes are symmetrically formed in the plate faces of the reinforcing plates and located on the two sides of the rear longitudinal beams; reinforcing rods are slidably connected to the first through holes in the same side in a matched and penetrating mode, and collision bearing beams are fixedly installed at the ends, away from the cross beams, of the reinforcing rods. A baffle is fixedly installed on the reinforcing rod and located on the side, away from the cross beam, of each reinforcing plate. Buffering springs are fixedly installed between the baffles and the opposite reinforcing plates, the reinforcing rods are sleeved with the buffering springs, and connecting plates are fixedly installed at the ends, close to the cross beams, of the reinforcing rods. According to the rear longitudinal beam, the impact force generated by collision is dispersed on the beam body of the rear longitudinal beam, and meanwhile, the cross beam uniformly bears a part of the impact force, so that the situation that the whole rear longitudinal beam is bent due to the fact that the impact force is concentrated on the end part of the rear longitudinal beam is avoided, and the safety of an automobile is improved.
本发明涉及一种汽车后纵梁总成加强件结构;包括两后纵梁和横梁,所述横梁的两端分别固定安装在两后纵梁上,所述后纵梁上且位于其端部与横梁之间固定安装有若干个加强板,所述加强板的板面且位于后纵梁的两侧对称设有第一贯通孔,同侧的若干个所述第一贯通孔相配合贯穿滑动连接有加强杆,所述加强杆远离横梁的一端固定安装有承撞梁。所述加强杆上且位于每个加强板远离横梁的一侧均固定安装有挡板。所述挡板与相对的加强板之间固定安装有缓冲弹簧,所述缓冲弹簧套设在加强杆上,所述加强杆靠近横梁的一端固定安装有连接板;本发明将冲撞产生的冲击力分散在后纵梁的梁身上,同时也使横梁均匀的承受一部分冲击力,从而避免了因冲击力都集中在后纵梁的端部,而使整个后纵梁发生弯曲,提高了汽车的安全性。
