Abstract

Provided is an electronic device including: a first and second housings; a display; and a hinge module connecting the first and second housings, the hinge module comprising: a rotation structure including first and second rotation members, and a rotation bracket for accommodating the first and second rotation members; and an interlocking structure including first and second spiral rotation members, a first guide member which surrounds at least a portion of the first spiral rotation member, a second guide member which surrounds at least a portion of the second spiral rotation member, and a slide member including a first through hole for accommodating the first spiral rotation member, and a second through hole for accommodating the second spiral rotation member, the slide member being configured to slide based on the movement of the first spiral rotation member or the second spiral rotation member.

Claims (63)

1 . An electronic device comprising:

a first housing;

a second housing;

a hinge module connected with the first housing and the second housing;

a hinge cover at least partially disposed between the first housing and the second housing; and

a flexible display disposed in the first housing and the second housing across the hinge module, wherein the hinge module includes:

a rotating structure including:

a first rotating member connected with the first housing;

a second rotating member connected with the second housing; and

a rotating bracket at least partially accommodated in a first portion of an accommodating recess of the hinge cover, and accommodating at least one portion of the first rotating member and at least one portion of the second rotating member; and

an interlocking structure including:

a first spiral rotating member connected with the first housing;

a second spiral rotating member connected with the second housing; and

a slide member at least partially spaced apart from the rotating structure and at least partially accommodated in a second portion of the accommodating recess of the hinge cover, and including a first area connected to at least one portion of the first spiral rotating member; and

a second area connected to at least one portion of the second spiral rotating member; and

wherein the slide member is configured to move based on a motion of at least one of the first spiral rotating member or a motion of the second spiral rotating member.

2 . The electronic device of claim 1 , wherein the first area of the slide member comprises a first through hole configured to accommodate at least one portion of the first spiral rotating member, and

wherein the second area of the slide member comprises a second through hole configured to accommodate the at least one portion of the second spiral rotating member.

3 . The electronic device of claim 1 , wherein the rotating bracket comprises:

a first rotating space configured to accommodate the at least one portion of the first rotating member and providing a first rotational axis; and a second rotating space configured to accommodate the at least one portion of the second rotating member and providing a second rotational axis substantially parallel to the first rotational axis.

4 . The electronic device of claim 3 , wherein

the first area includes a first outer surface spaced apart from the first rotational axis by a first distance and a first inner surface spaced apart from the first rotational axis by a second distance shorter than the first distance, and

wherein the second area includes a second outer surface spaced apart from the second rotational axis by the first distance and a second inner surface spaced apart from the second rotational axis by the second distance.

5 . The electronic device of claim 1 , wherein the hinge module further comprises

a fixing structure comprising:

a first detent member connected to the first housing and facing at least one portion of the slide member; and

a second detent member connected to the second housing and facing at least one portion of the slide member.

6 . The electronic device of claim 1 , wherein

the first spiral rotating member comprises:

a first spiral rotating rail and at least one first protruding area extending from the first spiral rotating rail,

wherein the at least one first protruding area protrudes in a length direction of the interlocking structure and faces or contacts at least one jammed side of the slide member,

wherein the second spiral rotating member comprises

a second spiral rotating rail and

at least one second protruding area extending from the second spiral rotating rail, and

wherein the at least one second protruding area protrudes in the length direction of the interlocking structure and faces or contacts at least one jammed side of the slide member.

7 . The electronic device of claim 6 , wherein the slide member comprises a first structure configured to spirally rotate the first spiral rotating member around a first rotational axis, and a second structure for spirally rotating the second spiral rotating member around a second rotational axis.

8 . The electronic device of claim 1 , wherein

the first spiral rotating member comprises: a first bracket connected with the first housing; and

a first spiral rotating bracket extended from the first bracket and configured to rotate with respect to the first area of the slide member, and

wherein the second spiral rotating member comprises a second bracket connected with the second housing; and a second spiral rotating bracket extended from the second bracket and configured to rotate with respect to the second area of the slide member.

9 . The electronic device of claim 8 , wherein the hinge module further comprises:

a first guide member connected with the first housing and surrounding the at least one portion of the first spiral rotating member; and

a second guide member connected with the second housing and surrounding the at least one portion of the second spiral rotating member, wherein the first spiral rotating bracket comprises: a first spiral rotating rail facing the first guide member; and

a first protruding area extended from the first spiral rotating rail, and wherein the second spiral rotating bracket comprises: a second spiral rotating rail facing the second guide member; and

a second protruding area extending from the second spiral rotating rail.

10 . The electronic device of claim 1 , wherein the hinge cover is configured to guide a movement of the slide member.

11 . The electronic device of claim 1 , wherein a distance between the slide member and the rotating structure is configured to vary based on an angle between the first housing and the second housing.

12 . The electronic device of claim 1 , wherein the rotating bracket comprises:

a first rotating recessed portion configured to accommodate the at least one portion of the first rotating member; and

a second rotating recessed portion configured to accommodate the at least one portion of the second rotating member.

13 . The electronic device of claim 12 ,

wherein the first rotating member is configured to rotate about a first rotational axis provided by the first rotating recessed portion, and

wherein the second rotating member is configured to rotate about a second rotational axis provided by the second rotating recessed portion.

14 . The electronic device of claim 1 , wherein the first area of the slide member includes at least one first surface, and the second area of the slide member includes at least one second surface, and

wherein the first spiral rotating member rotates at least partially in contact with the at least one first surface and the second spiral rotating member rotates at least partially in contact with the at least one second surface.

15 . The electronic device of claim 14 , wherein the

at least one first surface of the first area of the slide member is in a spiral shape, and the at least one second surface of the second area of the slide member is in a spiral shape.

16 . The electronic device of claim 1 , wherein the slide member is formed in a single piece.

17 . The electronic device of claim 1 , wherein the hinge module further comprises a first hinge module and a second hinge module spaced apart from the first hinge module, and

wherein the interlocking structure is disposed between the first the hinge module and the second hinge module.
