Hinge structure with rotary actuator

Abstract

The present invention discloses a hinge structure used in a folding mobile phone, the initial opening action is accomplished by converting the pressing stroke of the action member into the rotational movement of the hinge by means of a cam / cam follower mechanism. Therefore, an undesired reaction caused by an internal force between the two parts to be opened is avoided, and a smooth opening action without shock can be achieved. In particular, the hinge may be arranged such that the hinge is normally pushed in the opening direction while keeping the joints engaged so that the hinge is in a fully folded state, and the hinge is elastically recoverable in the opening direction by pressing the action member thereby disengaging the adapter.

Description

technical field [0001] The present invention relates to a hinge for connecting two parts so that the two parts can move angularly relative to each other, and more particularly to a hinge structure combined with a rotary actuator and an elastic drive mechanism so that one of the parts can be moved Folds and unfolds relative to another widget. Background technique [0002] Most existing portable phones are provided with a microphone unit and a speaker unit connected by a hinge so as to be opened during use and folded away when not in use. In order to improve the convenience of such a foldable telephone device, a hinge opening / closing device is disclosed in Japanese Patent Application Publication No. 8-125725, which stabilizes the two parts of the telephone device in a closed or folded state It is securely held and easily opened or opened by using only one hand. In this hinge opening / closing device, a torsion coil spring is used to provide rotational driving force to the hing...

Problems solved by technology

However, both methods are difficult to obtain suitable initial operating speed, sufficiently small operating force, and smooth operation throughout the entire stroke of operation.
