The invention discloses a front subframe rear mounting point structure and a vehicle, the front subframe rear mounting point structure comprises a reinforcing structure, the reinforcing structure comprises an upper reinforcing plate and a lower reinforcing plate which are connected to a vehicle body, and a cavity is formed between the upper reinforcing plate and the lower reinforcing plate; the bolt sleeve is arranged in the cavity, and the two ends of the bolt sleeve are fixedly connected with the upper reinforcing plate and the lower reinforcing plate correspondingly; the connecting bolt is sleeved with the bolt sleeve and used for being connected with the front auxiliary frame; the lower reinforcing plate is provided with a first weakening area, and the first weakening area is correspondingly located on the tail side of the lower end of the bolt sleeve in the X direction; a second weakening area is arranged on the upper reinforcing plate and arranged in the circumferential direction of the upper portion of the bolt sleeve. Gradient tearing deformation can be formed in the vertical direction by comprehensively arranging the first weakening area and the second weakening area on the upper reinforcing plate and the lower reinforcing plate; the probability that the front auxiliary frame automatically falls off in the collision process is greatly increased, and the safety of the vehicle is improved; in addition, the strength design of the mounting points is considered, and enough strength can be achieved.

    本发明公开了一种前副车架后安装点结构及车辆,包括:加强结构,包括连接于车身的上加强板和下加强板,上加强板和下加强板之间形成有空腔;螺栓套,设置于空腔内且两端分别对应的与上加强板和下加强板固定连接;连接螺栓,内套于螺栓套内用于前副车架的连接;下加强板上设有第一弱化区,第一弱化区对应的位于螺栓套下端沿X向的车尾侧;上加强板上设有第二弱化区,第二弱化区沿螺栓套上部的周向布置;本发明通过综合在上加强板和下加强板上设置的第一弱化区和第二弱化区可以在竖向上形成梯度的撕裂变形;极大的提升了碰撞过程中前副车架自动脱落的机率,提升车辆安全性;另外,兼顾了安装点强度设计,可以具有足够的强度。
