A fascinating exterior appearance is one of the most important values for customers so the realization of the innovative styling has been a major topic for car makers for several years. Also, since the base of autonomous driving and electric vehicle is being expanded recently, it is essential to not only create high-tech image on a vehicle but also realize the engineering design in reality. From that point of view, the auto flush handle can be unique sales point to enhance the degree of the completion of the exterior styling. The purpose of this study is to establish the kinematic system of auto flush door handle to overcome the exterior handicaps such as not only the excessive exposure of the internal area on the deployed position but also to determine the proper operating speed. In order to resolve these issues, the Scott-Russell mechanism is applied to the auto flush handle system. The mechanism is applied to realize the straight motion so exterior quality can be improved to minimize inner gap and prevent link exposure. In…
