The invention discloses an automobile rearview mirror folding device which comprises a shell arranged on an output shaft in a sleeving mode, an output gear, a base and a connecting base, the shell is fixedly connected with the base, the base and the connecting base are embedded through a first limiting protruding block assembly, the output gear and the connecting base are embedded through a second limiting protruding block assembly, and the shell is fixedly connected with the output gear. An angle gap is reserved between the output gear and the connecting base, a first cam assembly is arranged between the output gear and the base, a second cam assembly is arranged between the output gear and the shell, and under the action of the electric driving unit, the output gear rotates relative to the connecting base so as to eliminate the reserved angle gap, and meanwhile the shell and the base are integrally lifted upwards. And therefore, the base is separated from the connecting seat. The folding device is simple in overall structure, the lifting operation process is smoother, shaking and abrasion during folding are reduced, and meanwhile impact force borne by the output gear is small.

    本发明公开了一种汽车后视镜折叠装置,包括套装于输出轴上的壳体、输出齿轮、基座及连接座,所述壳体与基座固定连接,所述基座与连接座之间通过第一限位凸块组件相嵌合,所述输出齿轮与连接座之间通过第二限位凸块组件相嵌合,且输出齿轮与连接座之间预留角度间隙,所述输出齿轮与基座之间设有第一凸轮组件,所述输出齿轮与壳体之间设有第二凸轮组件,在电驱动单元作用下,输出齿轮相对连接座转动以消除预留角度间隙,同时将壳体与基座整体向上抬升,从而使基座与连接座相分离。该折叠装置整体结构简单,抬升运行过程也更为顺畅,并且减少了折叠时的抖动及磨损,同时输出齿轮所受到的冲击力也较小。
