The invention relates to the technical field of automobile rearview mirrors, and discloses a frame type rearview mirror upper support non-rigid connecting structure which comprises an upper end and an upper support, a screw of a bolt sequentially penetrates through the upper end and the upper support from top to bottom, a connecting cylinder allowing the screw to penetrate through is arranged below the upper end, the connecting cylinder is sleeved with a PU elastomer damping gasket, and the upper end of the upper support is connected with the upper end of the upper support. The upper surface of the upper support is downwards provided with a first connecting groove allowing the connecting cylinder to be inserted therein, the upper support is further internally provided with a second connecting groove communicated with the first connecting groove, the screw sequentially penetrates through the upper end and the connecting cylinder to enter the second connecting groove, the lower end of the screw is sleeved with an installation gasket, and the lower end of the screw is further provided with a nut abutting against the installation gasket. The outer diameter of the mounting gasket is larger than the inner diameter of the first connecting groove and smaller than the inner diameter of the second connecting groove. According to the non-rigid connecting structure of the upper support of the frame type rearview mirror, the rigidity of the connecting structure of the upper support and the mirror rod is reduced, so that the inherent frequency of a rearview mirror assembly is reduced, and the purpose of avoiding the resonance frequency band of a whole vehicle is achieved.

    本发明涉及汽车后视镜技术领域,公开了一种框架式后视镜上支座非刚性连接结构,包括上端头和上支座,螺栓的螺杆从上往下依次穿过上端头和上支座,上端头的下方设有供螺杆穿过的连接筒,连接筒上套置有PU弹性体减震垫片,上支座上表面向下开有供连接筒插入的第一连接槽,上支座内还开有与第一连接槽连通的第二连接槽,螺杆依次穿过上端头和连接筒进入第二连接槽,螺杆的下端套置有安装垫片,螺杆的下端还设有抵住安装垫片的螺母,安装垫片的外径大于第一连接槽的内径,小于第二连接槽的内径。本发明框架式后视镜上支座非刚性连接结构,降低了上支座与镜杆连接结构刚性,从而降低后视镜总成固有频率,以达到避开整车共振频段的目的。
