摘要： The present disclosure discloses an electric folding device for outer rearview mirror of a vehicle, which includes a shell, a foundation bed, a base, a pin shaft, an electric driving unit used for driving the shell to rotate relatively to the base around the axis of the pin shaft a spring arranged on the pin shaft in a sleeving mode, and a connecting piece which makes the shell manually rotate relatively to the foundation bed. A cam assembly is provided among the connecting piece, the foundation bed and the base. During the electric folding process, driven by the electric driving unit, the cam assembly enables the, foundation bed to lift up and rotate along the pin shaft through the relative slide of the cam assembly and the elastic force of the spring. The device is compact in structure, with better anti-jitter performance, smooth electric folding process, and less folding failure.
