The invention discloses a side wall D column reinforcing structure which comprises a reinforcing beam body, one end of the reinforcing beam body extends towards a wheel cover on the front side of an automobile to form a wheel cover connecting end, and the other end of the reinforcing beam body extends towards one side of a D column on the opposite side to form a D column connecting end. The wheel cover connecting end of the stiffening beam body is connected with a wheel cover of an automobile; the D column connecting end of the stiffening beam body is connected with a D column of the automobile; a transition part is arranged in the middle of the stiffening beam body, the bottom of the transition part is connected with a rear floor body of the automobile, and the side face of the transition part is connected with a side wall outer plate extending plate. According to the structure, the stiffening beam body is additionally arranged to effectively reinforce the rigidity and strength of the area, and under the torsion working condition, local deformation caused by the fact that a wheel cover and a D column are not effectively connected is reduced, so that the torsion rigidity and modality of a framework are effectively improved, and the overall performance is improved.
本发明公开了一种侧围D柱的加强结构,包括加强梁本体、加强梁本体一端朝向汽车前侧的轮罩延伸以形成为轮罩连接端,加强梁本体的另一端朝向相对一侧的D柱一侧延伸以形成为D柱连接端;加强梁本体的轮罩连接端与汽车的轮罩连接;加强梁本体的D柱连接端与汽车的D柱连接;加强梁本体的中间位置为过渡部分,过渡部分的底部与汽车的后地板本体连接,过渡部分的侧面与侧围外板延伸板连接。本发明的结构通过增加加强梁本体以实现与有效的加强此区域的刚强度,在扭转工况下,减少了该处因轮罩与D柱无有效连接引起的局部变形,从而有效地提升骨架的扭转刚度和模态,从而提升整体性能。
