The invention relates to the technical field of vehicle body rear wall beams, in particular to a structure for improving the torsional rigidity of a convex rear wall and a white vehicle body. The structure for improving the torsional rigidity of the convex rear wall comprises a rear wall outer plate, a rear wall lower cross beam, a rear wall longitudinal beam and a reinforcing piece. The rear wall lower cross beam is arranged on the rear wall outer plate in an attached mode. The rear wall longitudinal beam is connected with the rear wall outer plate and connected with the rear wall lower cross beam in the length direction perpendicular to the rear wall lower cross beam, and a beam cavity is formed between the rear wall longitudinal beam and the rear wall outer plate. The reinforcing piece is arranged at the bending point of the rear wall longitudinal beam and located in the beam cavity. According to the structure for improving the torsional rigidity of the convex rear wall and the body-in-white, the problem that the torsional rigidity of the convex rear wall is insufficient in the prior art is solved.
本申请涉及车身后围梁技术领域,特别涉及一种用于提升凸后围扭转刚度的结构和白车身。所述用于提升凸后围扭转刚度的结构包括后围外板、后围下横梁、后围纵梁和加强件。其中,所述后围下横梁贴合设置于所述后围外板上;所述后围纵梁与所述后围外板相连接,并沿垂直于所述后围下横梁的长度方向与后围下横梁连接,且所述后围纵梁与后围外板之间具有梁腔;所述加强件设置在后围纵梁的折弯点处,并位于所述梁腔中。本申请实施例通过提供一种用于提升凸后围扭转刚度的结构和白车身,以解决相关技术中凸后围扭转刚度不足的问题。
