Abstract
The present invention is a mobile terminal capable of switching between a first and second state, expanded in a first direction. The mobile terminal comprising: a body with a first and second frame, which can slide in the first or second direction, a flexible display unit covering one side of the body, with a front and rear surface connected by a side surface, a driving unit for sliding the first frame relative to the second frame using a motor mounted on the second frame. The driving unit includes a motor, a pinion gear, a rack gear and a gear cover covering at least a portion of the rack gear.
Claims11
A mobile terminal switchable to a first state and to a second state extended in a first direction in the first state, the mobile terminal comprising:
- a body including a first frame and including a second frame coupled to a rear face of the first frame to slidably move in the first direction or in a second direction;
- a flexible display unit including a front face portion positioned on a front face of the body, a rear face portion positioned on a rear face of the body, and a side face portion connecting the front face portion and the rear face portion and surrounding one side of the body;
- and
- a driving unit configured to slidably move the first frame in the first direction or the second direction with respect to the second frame,
- wherein the driving unit includes:
- a motor installed in the second frame;
- a pinion gear configured to rotate by receiving driving force of the motor;
- a rack gear positioned on the rear face of the first frame and configured to be extended in the first direction to perform linear motion by receiving the driving force of the motor through the pinion gear;
- and
- a gear cover configured to cover at a part of the rack gear and provide an open part allowing engagement between the rack gear and the pinion gear, and
- wherein the gear cover includes a bending-deformable material and covers the rack gear exposed to an outer side during movement of the first frame in the second direction from the second frame.
