|1. (WO2017031953) ELECTRIC FOLDING DEVICE FOR OUTSIDE REAR-VIEW MIRROR OF VEHICLE|
|Applicants:||NINGBO JINGCHENG CAR INDUSTRY CO., LTD
|Title:||ELECTRIC FOLDING DEVICE FOR OUTSIDE REAR-VIEW MIRROR OF VEHICLE|
An electric folding device for an outside ear-view mirror of a vehicle includes a shell (6), a foundation bed (3), a base (2), a pin shaft (7), an electric driving unit used for driving the shell (6) to rotate relative to the base (2) around the axis of the pin shaft (7), a spring (5) arranged on the pin shaft (7) in a sleeving mode, and a connecting piece (4) which makes the shell (6) manually rotate relative to the foundation bed (3). A cam assembly is provided among the connecting piece (4), the foundation bed (3) and the base (2). During the electric folding process, driven by the electric driving unit, the cam assembly enables the foundation bed (3) to lift up and rotate along the pin shaft (7) through the relative slide of the cam assembly and the electric driving unit and the elastic force of the spring (5). The device is compact in structure, the anti-shaking performance of the rear-view mirror is good, the electric folding process is smooth, and the phenomenon of folding failure is not likely to happen.
