The invention relates to the technical field of automobiles, and discloses an automobile body structure reinforcing rubber block which comprises a framework, a foaming material, an automobile body reinforcing plate and an automobile body inner plate. The foaming material is arranged on the framework in an injection molding manner; foaming materials are arranged between the framework and the automobile body reinforcing plate and between the framework and the automobile body inner plate. And the framework, the automobile body reinforcing plate and the automobile body inner plate are foamed and bonded through a foaming material to form an integral structure. According to the invention, the mounting buckle and the skeleton are formed by integral injection molding, and the epoxy resin foaming material and the PA6 skeleton are formed by secondary injection molding; the reinforcing rubber block assembly is clamped between the automobile body inner plate and the automobile body reinforcing plate; foaming is performed during coating electrophoresis drying, so that the reinforced rubber block assembly, the vehicle body inner plate and the vehicle body reinforcing plate form an integral structure, the collision performance of a vehicle can be improved, meanwhile, the rigidity and modality of the vehicle body can be improved, the local stress of the vehicle body is reduced, and NVH noise is reduced.
本发明涉及汽车技术领域,公开了一种汽车车身结构增强胶块,包括骨架、发泡材料、车身加强板和车身内板;所述发泡材料通过注塑成型的方式设置在骨架上;所述骨架和车身加强板之间、骨架和车身内板均设置有发泡材料;所述骨架、车身加强板和车身内板通过发泡材料发泡粘接形成整体结构。本发明安装卡扣与骨架采用一体注塑成型,环氧树脂发泡材料与PA6骨架采用二次注塑方式成型;增强胶块组件夹装于车身内板和车身加强板之间;在涂装电泳烘干时发泡,从而是增强胶块组件、车身内板和车身加强板形成整体结构,不仅可以提高车辆的碰撞性能,同时也可以提高车身刚度和模态,减少车身局部应力,降低NVH噪声。
