Abstract

An electronic device according to an embodiment of the present disclosure may comprise: a housing including a first housing and a second housing; a hinge structure comprising a hinge rotatably connecting the first housing and the second housing; a flexible display arranged on the housing; at least one heat-dissipation sheet arranged between the first housing and the flexible display; and a cushion member comprising a deformable material configured to absorb an impact arranged between the second housing and the flexible display.

First claim

What is claimed is:

1 . An electronic device comprising:
a housing comprising a first housing and a second housing; a hinge structure, comprising a hinge, rotatably connecting the first housing and the second housing; a flexible display disposed on the housing; at least one heat-dissipation sheet disposed between the first housing and the flexible display; and a cushion member, comprising a deformable material configured to absorb an impact, disposed between the second housing and the flexible display, wherein the cushion member comprises:
a first cushion member at least a portion of which is disposed between at least a portion of the hinge structure and the flexible display and is spaced apart from the flexible display by a first distance; and
a second cushion member disposed adjacent to the first cushion member and spaced apart from the flexible display by a second distance less than the first distance.

2 . The electronic device of claim 1 , wherein the first cushion member is disposed between the at least one heat-dissipation sheet and the second cushion member based on the electronic device being in an unfolded state.

3 . The electronic device of one of claim 1 , wherein a thickness of the first cushion member is less than a thickness of the second cushion member.

4 . The electronic device of claim 1 , further comprising:
a gap adjustment member comprising a tape bonded to at least a portion of the first cushion member and facing at least a portion of the flexible display.

5 . The electronic device of claim 1 , wherein the first cushion member and the second cushion member are integrally formed.

6 . The electronic device of claim 1 , wherein the at least one heat-dissipation sheet comprises:
a first heat-dissipation sheet; and a second heat-dissipation sheet spaced apart from the first heat-dissipation sheet and having a thickness substantially equal to a thickness of the first heat-dissipation sheet.

7 . The electronic device of claim 1 , further comprising:
a first adhesive member comprising an adhesive disposed between the first heat-dissipation sheet and the second heat-dissipation sheet and configured to bond the first heat-dissipation sheet and the second heat-dissipation sheet.

8 . The electronic device of claim 7 , wherein the first adhesive member comprises a pressure-sensitive adhesive PSA.

9 . The electronic device of claim 7 , wherein the first adhesive member comprises:
a first adhesive layer disposed on a surface of the first heat-dissipation sheet facing the second heat-dissipation sheet; and a second adhesive layer disposed on a surface of the second heat-dissipation sheet facing the first heat-dissipation sheet, and wherein the electronic device further comprises a film layer disposed between the first adhesive layer and the second adhesive layer.

10 . The electronic device of claim 9 , wherein the film layer comprises a polyimide film.

11 . The electronic device of claim 1 , further comprising:
a second adhesive member comprising an adhesive disposed between the first cushion member and the flexible display and configured to bond the first cushion member and at least a portion of the flexible display.

12 . The electronic device of claim 11 , wherein the second adhesive material comprises a pressure-sensitive adhesive (PSA).

14 . The electronic device of claim 11 , wherein a thickness of the second adhesive member is substantially equal to the first distance.

14 . The electronic device of claim 1 , further comprising:
at least one cover disposed on at least a portion of the at least one heat-dissipation sheet.

15 . The electronic device of claim 14 , further comprising:
a third adhesive member comprising an adhesive disposed between the at least one cover and the flexible display and configured to bond the at least one cover and at least a portion of the flexible display.
