Abstract

A portable electronic device includes a first frame, a second frame, a flexible display fixed to the first frame and fixed to the second frame, a hinge connected between the first frame and the second frame, the hinge being configured to control an angle between the first frame and the second frame; and an angle limiter for limiting the angle between the first frame and the second frame. The angle limiter includes a first stopper bracket coupled to the first frame, and a second stopper bracket coupled to the second frame. The first stopper bracket is spaced apart from the second stopper bracket in a closed state of the portable electronic device, and comes into contact with the second stopper bracket in an open state of the portable electronic device.

Claims (60)

1 . A portable electronic device comprising:

a first frame;

a second frame spaced from the first frame in a first direction when the portable electronic device is in an open state;

a hinge disposed between the first frame and the second frame, the hinge being configured to control an angle between the first frame and the second frame; and

an angle limiter configured to limit the angle between the first frame and the second frame, the angle limiter including a first stopper bracket coupled to the first frame and a second stopper bracket coupled to the second frame,

wherein each of the first stopper bracket and the second stopper bracket includes:

a first stopper; and

a second stopper,

wherein in the open state, the first stopper of the first stopper bracket comes into contact with the first stopper of the second stopper bracket in a thickness direction, and

wherein in the open state, the second stopper of the first stopper bracket comes into contact with the second stopper of the second stopper bracket in the first direction.

2 . The portable electronic device of claim 1 , wherein each first stopper includes:

a stopper hook; and

a stopper bump,

wherein the stopper hook of the first stopper bracket comes into contact with the stopper bump of the second stopper bracket, and

wherein the stopper hook of the second stopper bracket comes into contact with the stopper bump of the first stopper bracket.

3 . The portable electronic device of claim 2 , wherein the first stopper of the first stopper bracket is spaced from the first stopper of the second stopper bracket in a second direction perpendicular to the first direction.

4 . The portable electronic device of claim 3 , wherein the stopper hook of the first stopper bracket protrudes further towards the second stopper bracket than the stopper bump of the first stopper bracket.

5 . The portable electronic device of claim 4 , wherein a line connecting an end of the stopper hook of the first stopper bracket and an end of the stopper bump of the first stopper bracket is parallel to a first surface of the first frame and the second frame, in the open state.

6 . The portable electronic device of claim 3 , wherein each second stopper is located between the first stopper of the first stopper bracket and the first stopper of the second stopper bracket.

7 . The portable electronic device of claim 3 , wherein the first stopper bracket is oriented 180 degrees from the second stopper bracket, and

wherein the first stopper bracket has a same shape as the second stopper bracket.

8 . The portable electronic device of claim 2 , wherein each second stopper includes a supporting surface,

wherein the supporting surface of the second stopper of the first stopper bracket comes into contact with the supporting surface of the second stopper of the second stopper bracket in the open state, and

wherein the stopper hook of the first stopper bracket protrudes further towards the second stopper bracket than the supporting surface of the second stopper of the first stopper bracket.

9 . The portable electronic device of claim 8 , wherein each supporting surface protrudes further towards a surface of the first frame and the second frame than each stopper hook.

10 . The portable electronic device of claim 1 , wherein each of the first stopper bracket and the second stopper bracket further includes:

screw holes for attaching to a respective one of the first frame and the second frame; and

alignment protrusions inserted into guide holes formed in the respective one of the first frame and the second frame.

11 . The portable electronic device of claim 1 , further comprising a flexible display fixed to a first surface of the first frame and fixed to a first surface of the second frame,

wherein the flexible display covers a first surface of the hinge and a first surface of the angle limiter, and

wherein the flexible display including a foldable portion configured to have a varying curvature.

12 . A portable electronic device comprising:

a first frame;

a second frame;

a flexible display fixed to the first frame and fixed to the second frame;

a hinge connected between the first frame and the second frame, the hinge being configured to control an angle between the first frame and the second frame; and

an angle limiter configured to limit the angle between the first frame and the second frame, the angle limiter including:

a first stopper bracket coupled to the first frame; and

a second stopper bracket coupled to the second frame,

wherein each of the first stopper bracket and the second stopper bracket includes a first stopper,

wherein the first stopper bracket is configured to be spaced apart from the second stopper bracket in a closed state of the portable electronic device, and

wherein the first stopper of the first stopper bracket is configured to come into contact in a thickness direction with the first stopper of the second stopper bracket in an open state of the portable electronic device.

13 . The portable electronic device of claim 12 , wherein each of the first stopper bracket and the second stopper bracket includes a second stopper.

14 . The portable electronic device of claim 13 , wherein the second stopper of the first stopper bracket comes into contact with the second stopper of the second stopper bracket in a first direction in the open state, and

wherein the first frame is spaced from the second frame in the first direction.

15 . The portable electronic device of claim 13 , wherein each first stopper includes:

a stopper hook; and

a stopper bump,

wherein the stopper hook of the first stopper bracket comes into contact with the stopper bump of the second stopper bracket, and

wherein the stopper hook of the second stopper bracket comes into contact with the stopper bump of the first stopper bracket.

16 . The portable electronic device of claim 15 , wherein for each of the first stopper bracket and the second stopper bracket, the second stopper is positioned between the stopper hook and the stopper bump.

17 . The portable electronic device of claim 16 , wherein the second stopper of the first stopper bracket comes into contact the second stopper of the second stopper bracket in the open state.

18 . The portable electronic device of claim 12 , wherein the first stopper bracket is oriented 180 degrees from the second stopper bracket, and

wherein the first stopper bracket has a same shape as the second stopper bracket.

19 . The portable electronic device of claim 13 , wherein each second stopper includes a supporting surface,

wherein the supporting surface of the second stopper of the first stopper bracket comes into contact with the supporting surface of the second stopper of the second stopper bracket in the open state, and

wherein a stopper hook of the first stopper bracket protrudes further towards the second stopper bracket than the supporting surface of the second stopper of the first stopper bracket.

20 . The portable electronic device of claim 12 , wherein each of the first stopper bracket and the second stopper bracket further includes:

screw holes for attaching to a respective one of the first frame and the second frame; and

alignment protrusions inserted into guide holes formed in the respective one of first frame and the second frame.
