The invention discloses a bicolor mold wheel brow structure for automobile surface decoration, which comprises a part A, a transition body and a part B. The section of the part A and the section of the part B are of an L-shaped structure, the end part of the part A is bent in an L shape, and the outer side wall of the bent part is connected with the inner side wall of the part B. The transition body is in a long strip shape and is installed at the end part of the surface of the part B. The transition body is installed at the end part of the surface of the part B. The transition body extends in the extending direction of the part B, the top face of the transition body is connected with the middle of the bottom face of the part A in an attached mode, the transition body comprises a base and an elastic deformation layer, the elastic deformation layer is installed on the top face of the base, and the top face of the elastic deformation layer is an arc face. According to the structure, the elastic transition body is adopted to absorb the dimensional deviation accumulation of all chain rings of the dimensional chain, so that on the premise of meeting the target tolerance, the requirement on the tolerance of a single part is reduced, and the production cost is greatly reduced.
本发明公开了一种用于汽车表面装饰的双色模轮眉结构,包括:零件A、过渡体和零件B,所述零件A和零件B的截面为L形结构,零件A的端部呈L形弯折且弯折部位的外侧壁与零件B的内侧壁连接,所述过渡体呈长条状且安装在零件B的表面端部,所述过渡体沿着零件B的延伸方向进行延伸,且过渡体的顶面与零件A的底面中部贴合连接,所述过渡体包括底座和弹性形变层,所述弹性形变层安装在底座的顶面且弹性形变层的顶面呈弧面。本发明采用弹性过渡体吸收尺寸链所有链环的尺寸偏差累积,在满足目标公差的前提条件下,降低了对于零件单件公差要求,大幅降低了生产成本。
