  • Patent number: 10310566
    Abstract: The present disclosure provides a foldable mechanism of a mobile terminal and the mobile terminal. The foldable mechanism includes a soft support structure and a hard support structure embedded in the soft support structure. The foldable mechanism formed by the soft support structure and the hard support structure embedded in the soft support structure is used as a component for connecting a first housing and a second housing. When the mobile terminal is unfolded, the foldable mechanism formed by the soft support structure and the hard support structure is unfolded and turns into a flat structure connected to the first housing and the second housing. When the mobile terminal is folded, one side of the soft support structure away from the hard support structure shrinks inward. Therefore, the mobile terminal is prevented from having an abrupt exterior structure, and an exterior effect of the mobile terminal is improved.
