The invention provides a C-ring wheel cover structure reinforcer, belonging to the field of automobiles. The C-ring wheel cover structure reinforcer comprises a nylon glass fiber framework. In the invention, a framework part is made of nylon and glass fibers, has characteristics of low density, light structure and large specific strength, and is mainly used for resisting deformation and improvingthe rigidity of a wheel cover and a C-ring metal plate bracket; an epoxy resin structural adhesive is arranged on the surface of a skeleton and distributed in a honeycomb staggered manner, and the epoxy resin structural adhesive and three surface adhesives of a wheel cover, a floor and a C-ring metal plate connect three metal plates together to form an integral body; and the adhesive is pre-installed on the C-ring metal plate in a welding workshop through buckles, a structural expansion adhesive material is usually in an unexpanded state when the reinforcer is manufactured, but the structuralexpansion adhesive material expands after receiving a heating activation effect and the like when the reinforcer plays a role, and therefore, the structural expansion adhesive material is combined tothe surface of a structural part.
本发明提供一种C环轮罩结构加强件,涉及汽车领域,包括尼龙玻纤骨架。本发明中,骨架部分为尼龙+玻纤,密度低,具有结构轻,比强度大特点,主要作用为抵抗变形,增加轮罩与C环钣金支架的刚度,环氧树脂结构粘胶:在骨架表面,蜂窝状错开分布着粘胶,与轮罩、地板、C环钣金三个表面粘胶,将三个钣金连接在一起,形成整体,通过卡扣在焊装车间预安装在C环钣金上,在制造加强件时结构膨胀粘胶材料通常处于未膨胀状态,但在发挥作用时受到诸如加热激活作用后便引发膨胀,从而结合到结构件表面。
