Abstract

The present invention relates to a mobile terminal structure comprising: a body; a display deformed along the outer surface of the body by means of an external force; and a frame part which supports the display and which is modified into a shape of encompassing the outer surface of the body, wherein the frame part comprises: a rear plate which is coupled to one surface of the display and which can be modified together with the display so as to correspond to the outer surface of the body; and link parts which are respectively provided to both sides of the rear plate and which include a plurality of link members arranged in parallel to each other, and the display can be wound or unwound together with the rear plate along the outer surface of the body by means of the rotation between the connected link members of the link parts.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a body;
a display configured to be deformed along an outer surface of the body by an external force; and
a frame part that supports the display and is deformed to a shape surrounding the outer surface of the body,
wherein the frame part comprises:
a rear plate that is coupled to one surface of the display and is deformable so as to correspond to the outer surface of the body together with the display; and
link parts provided on both sides of the rear plate, respectively, and provided with a plurality of link members arranged side by side, a first link part and a second link part spaced apart from the display by a predetermined distance along a direction in which the display is unrolled and respectively disposed at upper and lower portions of the display to face each other, and
wherein,
the link parts allow the display to be rolled or unrolled along the outer surface of the body together with the rear plate by rotation between the link members connected to one another, the display and the link part are provided on a same surface of the rear plate, the display is rolled around the body to allow a front surface portion thereof to face an outside, and the first link part and the second link part are rolled together in a same direction along the outer surface of the body along the rear plate.

2. The mobile terminal of claim 1 , wherein the link parts define an rolled state of the display while being in close contact with the outer surface of the body, and define an unrolled state of the display while being spaced apart from the outer surface of the body.

3. The mobile terminal of claim 1 , wherein the display and the link part are provided on different surfaces of the rear plate, and
wherein the rear plate is exposed to the outside when the display is rolled around the body.

4. The mobile terminal of claim 1 , wherein a board mounting part is coupled to an end portion of the rear plate, and
wherein a flexible printed circuit board (FPCB) on which electronic devices are mounted is provided in the board mounting part.

5. The mobile terminal of claim 4 , wherein a battery is provided in the board mounting part.

6. The mobile terminal of claim 4 , wherein a sub mobile terminal is coupled to the board mounting part to allow independent driving of the display.

7. The mobile terminal of claim 1 , wherein the frame part further comprises a support bar provided at an end portion of the rear plate to connect the link parts disposed to face each other, and
wherein the support bar is coupled to one side of the outer surface of the body.

8. The mobile terminal of claim 7 , wherein a support bar seating groove is formed on the outer surface of the body to have a predetermined shape in a length direction, and is recessed in a shape corresponding to an outer surface of the support bar to allow the support bar to be seated therein.

9. The mobile terminal of claim 8 , wherein at least one first magnet is provided at one side of the support bar seating groove,
wherein at least one second magnet is provided at a position corresponding to the first magnet, and
wherein the first magnet and the second magnet form an attractive force by interaction to allow the support bar to be seated in the support bar seating groove.

10. The mobile terminal of claim 9 , wherein the first magnet is provided on one side of the outer surface of the body,
wherein a third magnet is provided on one side of the rear plate spaced farthest apart from the body when the frame part is in an unrolled state, and
wherein the third magnet provides an external force to allow the body to be in close contact with each other when the frame part is wound around the body.

11. The mobile terminal of claim 7 , wherein the link member comprises:
a first link member positioned at one end portion thereof and fixed to both ends of the support bar through a connection pin;
a second link member connected to the first link member, the second link member provided in plurality of the same shape to be arranged side by side; and
a third link member positioned at another end portion thereof and connected to the second link member.

12. The mobile terminal of claim 11 , wherein a connection protrusion protrudes from a front end portion of the second link member, and a guide protrusion protrudes from a rear end portion of the second link member,
wherein a connection groove is recessed into the guide protrusion, and
wherein the connection protrusion is inserted into the connection groove of the adjacent second link member to be coupled through the connection pin, so as to rotate with respect to each other.

13. The mobile terminal of claim 12 , wherein a first fastening hole having an oval shape is formed in the connection protrusion,
wherein a second fastening hole having a circular shape is formed in the guide protrusion, and
wherein the connection pin is inserted to pass through the first fastening hole of one of the plurality of second link members, and the second fastening hole of another one of the plurality of second link members, which are disposed adjacent to each other.

14. The mobile terminal of claim 13 , wherein a rotation limiter protrudes from the second link member to limit rotation beyond a set rotation angle.

15. The mobile terminal of claim 1 , wherein a mounting groove defined by a fixed space along an extension direction of the body is formed on a central portion of the body.

16. The mobile terminal of claim 15 , wherein a battery is provided in the mounting groove to supply power to the mobile terminal.

17. The mobile terminal of claim 15 , wherein a mounting member for supporting the mobile terminal is mounted to the mounting groove, and is configured to be pulled out by a user.

18. The mobile terminal of claim 15 , wherein a stylus for inputting a signal to the display is inserted into or drawn out from the mounting groove.

19. The mobile terminal of claim 18 , wherein the stylus receives an elastic force from an elastic member that is provided inside the body, so as to allow at least a portion thereof to be drawn out from the mounting groove.

20. The mobile terminal of claim 1 , wherein the link members are configured to be mutually rotatable between members adjacent to one another so as to define a rolled state of the display as a separation distance between the link members adjacent to one another decreases, and define an unrolled state of the display as the separation distance between the link members adjacent to one another increases.
