[0035] In an embodiment, when the electronic device 100 is in a flat state, the first housing 111 and the second housing 112 can be disposed side by side. In another embodiment, when the electronic device 100 is in a folded state, the first housing 111 and the second housing 112 can be disposed such that one surface of the first housing 111 and one surface of the second housing 112 face each other by rotation of the first housing 111 and the second housing 112 about a folding axis F.

[0036] In an embodiment, the hinge structure 150 may be connected to at least a portion of the first housing 111 and at least a portion of the second housing 112 to allow the first housing 111 and the second housing 112 to be folded or unfolded along a folding axis F therebetween.

[0037] According to an embodiment, the flexible display 120 may form one surface of the first housing 111 and one surface of the second housing 112. To support the flexible display 120, the first housing 111 and the second housing 112 may be formed of a metal material and / or a non-metal material having a certain rigidity.

[0038] In an embodiment, the flexible display 120 may include a first area 121 corresponding to at least one area of ​​the first housing 111 , a second area 122 corresponding to at least one area of ​​the second housing 112 , and a folding area 123 located between the first area 121 and the second area 122 .

[0039] In an embodiment, when the electronic device 100 is in a flat state, the first region 121, the folding region 123, and the second region 122 may be arranged side by side while facing the same direction. When the electronic device 100 is in a folded state, the first region 121 and the second region 122 may face each other, and the folding region 123 may be bent.

[0040] According to an embodiment, at least one region (eg, the first region 121 and the second region 122 ) of the flexible display 120 may be fixed to one surface of the first housing 111 and one surface of the second housing 112 .

[0041] In an embodiment, the covers 131 and 132 may be located at lower ends of the first housing 111 and the second housing 112 and may form a rear surface of the electronic device 100. For example, the covers 131 and 132 may include a first cover 131 connected to the first housing 111, and a second cover 132 connected to the second housing 112. In another example, the first cover 131 and the first housing 111 may be integrally formed with each other, and the second cover 132 and the second housing 112 may be integrally formed with each other.

[0042] In an embodiment, a first edge P1 parallel to the folding axis F may be defined among the edges of the first housing 111. A second edge P2 parallel to the folding axis F may be defined among the edges of the second housing 112. In various embodiments, the folded state of the electronic device 100 may include a fully folded state (e.g., Figure 1b ), the first edge P1 and the second edge P2 intersect with each other in the fully folded state.

[0043] refer to Figure 1c The first housing 111 may include a first support plate 141. A portion of the flexible display 120 may be disposed on the first support plate 141.

[0044] In an embodiment, the second housing 112 may include a second support plate 142. A portion of the flexible display 120 may be disposed on the second support plate 142. For example, the second region 122 may be attached to the second support plate 142. For example, the second metal plate 126 may be attached to the second support plate 142.

[0045] refer to Figure 1c , the electronic device 100 may include a hinge structure 150 connected to the first housing 111 and the second housing 112. In an embodiment, the hinge structure 150 may connect the first housing 111 and the second housing 112 to allow the first housing 111 and the second housing 112 to fold along a folding axis F therebetween. In an embodiment, at least a portion of the hinge structure 150 may be disposed in the hinge housing 119.

[0046] In an embodiment, the hinge structure 150 may include a first rotation axis R1 , a second rotation axis R2 , a first rotation component 151 , and a second rotation component 152 .

[0047] In an embodiment, the first rotating component 151 may be configured to rotate about a first rotation axis R1. The first rotating component 151 may be connected to the first support plate 141 of the first housing 111. For example, the first rotating component 151 may be fastened to the first support plate 141 via rivets. In an embodiment, the second rotating component 152 may be configured to rotate about a second rotation axis R2. The second rotating component 152 may be connected to the second support plate 142 of the second housing 112. For example, the second rotating component 152 may be fastened to the second support plate 142 via rivets. In an embodiment, the first rotation axis R1 and the second rotation axis R2 may be positioned substantially symmetrically with respect to the folding axis F.

[0048] Therefore, when the electronic device 100 is folded or unfolded, the first housing 111 and the first rotating member 151 can rotate together about the first rotation axis R1 by a predetermined angle, and the second housing 112 and the second rotating member 152 can rotate together about the second rotation axis R2 by a predetermined angle. As the first housing 111 and the second housing 112 rotate about the first rotation axis R1 and the second rotation axis R2, respectively, the first housing 111 and the second housing 112 can be folded along the folding axis F therebetween.

[0049] In an embodiment, the hinge structure 150 may further include a first supporting portion 153 and a second supporting portion 154 that support the rear surface of the flexible display 120. For example, the first supporting portion 153 may support at least a portion of the rear surface of the first region 121 of the flexible display 120. For example, the second supporting portion 154 may support at least a portion of the rear surface of the second region 122 of the flexible display 120.

[0050] In an embodiment, the flexible display 120 may further include metal plates 125 and 126 disposed on the rear surface thereof. In an embodiment, the metal plates 125 and 126 may include a first metal plate 125 disposed on a portion of the rear surface of the first region 121 and the rear surface of the folding region 123, and a second metal plate 126 disposed on a portion of the rear surface of the second region 122 and the rear surface of the folding region 123.

[0051] In an embodiment, the first metal plate 125 and the second metal plate 126 may include a metal material having a predetermined rigidity.

[0052] In an embodiment, the first metal plate 125 may be attached to at least a portion of the first region 121 and may extend toward the folding region 123. The second metal plate 126 may be attached to at least a portion of the second region 122 and may extend toward the folding region 123. For example, the first metal plate 125 and the second metal plate 126 may not be attached to the folding region 123. Thus, in a flat state, the first metal plate 125 and the second metal plate 126 may support the folding region 123 to allow the folding region 123 to remain flat. In a folded state, the first metal plate 125 and the second metal plate 126 may be separated from the folding region 123 and may remain substantially flat. For example, in the folded state, the first metal plate 125 and the second metal plate 126 may extend in a direction tangential to the curved folding region 123.

[0055] In an embodiment, each of the protective structures 200 may include a fixed part 210 fixed to the hinge housing 119, and a movable part 230 attached to the fixed part 210 so as to be movable. In the illustrated embodiment, the movable part 230 may include a first movable part 230a adjacent to the first decoration member 113, and a second movable part 230b adjacent to the second decoration member 114.

[0056] In an embodiment, opposite edges of the folding region 123 in the direction of the folding axis F may be defined as a third edge P3 and a fourth edge P4. The third edge P3 and the fourth edge P4 may extend in a direction perpendicular to the folding axis F and may be parallel to each other.

[0057] In an embodiment, each of the third edge P3 and the fourth edge P4 of the folding region 123 may be covered by at least a portion of the moving part 230 of the protective structure 200. For example, when the flexible display 120 is viewed from above, each of the third edge P3 and the fourth edge P4 may overlap with the moving part 230 of the protective structure 200. Therefore, the protective structure 200 may prevent external impact force from being directly applied to the folding region 123.

[0058] In embodiments, the first housing 111 may include a first decorative member 113 that covers at least a portion of the perimeter of the first region 121 of the flexible display 120, and a first screen wall 115 that faces the first movable part 230a of the protective structure 200.

In various embodiments, the first decorative member 113 may be integrally formed with the first housing 111, or may be detachably coupled to the first housing 111. For example, the first decorative member 113 may extend from the first housing 111 to cover a portion of the surface of the first region 121. In embodiments, the first screen wall 115 may be formed to conceal at least a portion of the first movable part 230a when the electronic device 100 is viewed from a side.

[0059] In embodiments, the second housing 112 may include a second decorative member 114 that covers at least a portion of the perimeter of the second area 122 of the flexible display 120, and a second screen wall 116 that faces the second movable part 230b of the protective structure 200. For example, when the flexible display 120 is viewed from above, the second decorative member 114 may overlap at least a portion of the perimeter of the second area 122. In various embodiments, the second decorative member 114 may be integrally formed with the second housing 112, or may be detachably coupled to the second housing 112. For example, the second decorative member 114 may extend from the second housing 112 to cover a portion of the surface of the second area 122. In embodiments, the second screen wall 116 may be formed to conceal at least a portion of the second movable part 230b when the electronic device 100 is viewed from a side.

[0060] refer to Figure 2a and Figure 2b As the electronic device 100 moves from the flat state to the folded state, the area of ​​the fixed part 210 exposed between the first movable part 230 a and the second movable part 230 b of the protection structure 200 may increase.

[0061] In various embodiments, when the electronic device 100 moves from a flat state to a folded state, the moving member 230 may move in a direction away from the folding axis F and toward the surface of the folding region 123 of the flexible display 120. When the electronic device 100 is folded or unfolded, the moving member 230 may move along a predetermined path so as not to overlap with a trajectory along which the folding region 123 of the flexible display 120 is deformed.

[0062] In various embodiments, when the electronic device 100 moves from a flat state to a folded state, the first movable part 230a can move so that it at least partially overlaps the first decorative member 113. For example, in the folded state, at least a portion of the first movable part 230a can be accommodated in the first accommodation space 117a between the first decorative member 113 and the surface of the flexible display 120. For example, as the electronic device 100 is folded to a greater extent (e.g., as the folding area 123 deforms with a greater curvature), the first movable part 230a can be further accommodated in the space.

[0063] In various embodiments, when the electronic device 100 moves from a flat state to a folded state, the second movable part 230b can move so that it at least partially overlaps the second decorative member 114. For example, in the folded state, at least a portion of the second movable part 230b can be accommodated in the second accommodation space 117b between the second decorative member 114 and the surface of the flexible display 120. For example, as the electronic device 100 is folded to a greater extent (e.g., as the folding area 123 deforms with a greater curvature), the second movable part 230b can be further accommodated in the space.

Therefore, the moving member 230 can move relative to the elastic member 258 and the guide member 250, and the elastic member 258 can be compressed or stretched while being fixed to the guide member 250. In addition to the above structure, the guide member 250 may include various structures for fixing the elastic member 258.

[0111] In an embodiment, the moving part 230 may be movable relative to the fixed part 210. For example, the moving part 230 may be rotated and linearly moved while maintaining contact with the fixed part 210.

[0112] In an embodiment, the rotation of the moving member 230 may include the moving member 230 rotating about the central axis of the arcuate surface of the guide rail 211 (eg, Figure 7c The central axes C1 and C2) rotate.

[0113] In an embodiment, the linear movement of the moving member 230 may include the moving member 230 moving in a direction away from the central protruding portion 223 or in a direction toward the central protruding portion 223 .

[0114] In an embodiment, the rotation and linear movement of the moving member 230 may be performed simultaneously.

[0115] In an embodiment, in the rotation of the moving member 230 , the rotation angle may be defined as a rotation angle of the extension surface S extending from the first surface 241 of the cover portion 231 .

[0116] In an embodiment, the moving member 230 may perform a first operation including a first rotation and a first linear movement (eg, Figure 8 ), and a second operation including a second rotation and a second linear movement (eg, Figure 9 ).

[0117] refer to Figure 8 , the first operation of the moving member 230 can be performed by the second supporting portion 232-2 along the surface of the second rail 211-2 (eg, Figure 7a 、 Figure 7b and Figure 7c The first operation may include a first rotation of the moving member 230 at a first angle q1 and a first linear movement of the moving member 230 at a first displacement L2-L1.

[0118] refer to Figure 8 , the moving part 230 can be moved from the first state A1 to the second state A2 by a first operation. The moving part 230 can be rotated by a first angle q1 from the first state A1 and can be linearly moved by a first displacement L2-L1 in a direction away from the central protruding portion 223. The rotation and linear movement of the moving part 230 can be performed simultaneously. In various embodiments, the first state A1 of the moving part 230 may include a case where the electronic device 100 is in a flat state (for example, Figure 10a ).

[0119] refer to Figure 9, the second operation of the moving member 230 can be performed by the first supporting portion 232-1 along the surface of the first rail 211-1 (eg, Figure 7a 、 Figure 7b and Figure 7c The second operation may include a second rotation of the moving member 230 at a second angle q2 and a second linear movement of the moving member 230 at a second displacement L4-L3.

[0120] refer to Figure 9 , the moving part 230 can be moved from the third state A3 to the fourth state A4 by the second operation. The moving part 230 can be rotated by a second angle q2 from the third state A3 and can be linearly moved by a second displacement L4-L3 in a direction away from the central protruding portion 223. The rotation and linear movement of the moving part 230 can be performed simultaneously. In various embodiments, the fourth state A4 of the moving part 230 can be when the electronic device is in a fully folded state (e.g., Figure 10c ) is the state of the moving part 230.

[0121] In various embodiments, the second state A2 may be substantially the same as the third state A3. In various embodiments, in the second state A2, the third state A3, or any state between the second state A2 and the third state A3, the first support portion 232-1 of the moving member 230 may be in contact with the first track 211-1, and the second support portion 232-2 of the moving member 230 may be in contact with the second track 211-2. In other words, the sum of the first angle q1 and the second angle q2 may be equal to or greater than 90 degrees. In order to continuously perform the first operation (e.g., Figure 8 ) and a second operation (e.g., Figure 9 ), the moving member 230 may be formed to include a state of being in contact with the first rail 211 - 1 and the second rail 211 - 2 at the same time.

[0122] refer to Figure 8 and Figure 9 , in the first operation, the moving member 230 may have a larger linear displacement than in the second operation.

[0123] For example, reference Figure 8 In the first state A1, the moving member 230 may be spaced apart from the central protruding portion 223 by a first length L1, and in the second state A2, the moving member 230 may be spaced apart from the central protruding portion 223 by a second length L2. The difference between the first length L1 and the second length L2 may refer to a first linear displacement L2-L1 of the moving member 230 in the first operation.

[0124] For example, reference Figure 9In the third state A3, the moving member 230 may be spaced apart from the central protruding portion 223 by a third length L3, and in the fourth state A4, the moving member 230 may be spaced apart from the central protruding portion 223 by a fourth length L4.

The first linear displacement L2-L1 may be greater than the second linear displacement L4-L3.

[0125] refer to Figure 8 and Figure 9 In the first operation, the moving member 230 may have a smaller rotation angle than in the second operation. For example, the first angle q1 in the first rotation may range from 0 degrees to 37 degrees, and the second angle q2 in the second rotation may range from 33 degrees to 90 degrees.

[0126] Figure 10a 、 Figure 10b and Figure 10c 2 is a view illustrating the operation of the protection structure of the electronic device according to the embodiment. Figure 10a is a view showing the protective structure of the electronic device in a flat state. Figure 10b is a view showing a protective structure of an electronic device in a folded state. Figure 10c is a view showing the protective structure of the electronic device in a completely folded state.

[0127] In an embodiment, the flat state may include a state in which the first region 121 and the second region 122 of the flexible display 120 form substantially the same plane. For example, the flat state may include a state in which the folding region 123 is flat. For example, the flat state may include a state in which the normal vector n1 of the first region 121 and the normal vector n2 of the second region 122 are substantially parallel to each other.

[0128] In an embodiment, the folded state may include a state in which the folded region 123 of the flexible display 120 is formed into a first curved surface. A normal vector n1 of the first region 121 may form a first angle q1 with a normal vector n2 of the second region 122.

[0129] In embodiments, the fully folded state may include a state in which the folded region 123 of the flexible display 120 is formed into a second curved surface. The second curved surface may have a greater curvature than the first curved surface. For example, the normal vector n1 of the first region 121 may form a second angle q2 with the normal vector n2 of the second region 122 that is greater than the first angle q1. For example, the second angle q2 may be substantially 180 degrees, or may be 180 degrees or greater.

[0130] In an embodiment, at least a portion of the cover portion 231 of the first movable member 230a can be accommodated in the first accommodation space 117a. At least a portion of the cover portion 231 of the second movable member 230b can be accommodated in the second accommodation space 117b. For example, in a flat state, when the flexible display 120 is viewed from above, at least a portion of the cover portion 231 can overlap with the first and second decorative members 113 and 114.

[0131] In an embodiment, the moving member 230 may be configured such that: when the electronic device 100 moves from the flat state to the folded state, the cover 231 is further accommodated in the accommodation spaces 117a and 117b. By moving the cover 231, the folding region 123 can be prevented from colliding with the cover 231 when the electronic device 100 is unfolded or folded.

[0132] refer to Figure 10a In a flat state, the cover portion 231 may form substantially the same plane as the first and second decoration members 113 and 114 . The cover portion 231 may form a first gap G1 with the surface of the folding region 123 .

[0133] refer to Figure 10b In the folded state, the cover portion 231 may form a second gap G2 with the surface of the folding region 123. The second gap G2 may be smaller than the first gap G1.

[0134] refer to Figure 10c In the fully folded state, the cover portion 231 may form a third gap G3 with the surface of the folding region 123. The third gap G3 may be smaller than the first gap G1.

[0135] In an embodiment, the movable member 230 can move so that the gap formed between the cover portion 231 and the folding area 123 changes depending on the state of the electronic device 100. In addition, as the electronic device 100 is folded to a greater extent, the movable member 230 can be further accommodated in the accommodation spaces 117a and 117b. As described above, when the electronic device 100 is unfolded or folded, the movable member 230 can move along a predetermined path so that the folding area 123 and the movable member 230 do not collide with each other.

[0136] In an embodiment, the predetermined path (the predetermined path along which the moving member 230 moves) may vary depending on the shape of the guide groove 253 formed in the guide member 250 .

[0137] refer to Figure 10a 、 Figure 10b and Figure 10cAs the electronic device 100 moves from the flat state to the fully folded state, the elastic member 258 can be compressed. For example, when the electronic device 100 is in the flat state, the elastic member 258 can be in a balanced state. In various embodiments, the elastic member 258 can include a torsion spring.

[0138] In an embodiment, when the electronic device 100 moves from the flat state to the fully folded state, the distance from the center protrusion 223 to the first housing 111 and the second housing 112 can change. For example, referring to Figure 10a 、 Figure 10b and Figure 10c , as the electronic device 100 moves from the flat state to the folded state, the distance from the center protrusion 223 of the fixed part 210 to the decorative members 113 and 114 can decrease. For example, in the flat state of Figure 10a , the decorative members 113 and 114 can be spaced apart from the center protrusion 223 at a first distance d1. For example, in the folded state of Figure 10b , the decorative members 113 and 114 can be spaced apart from the center protrusion 223 at a second distance d2. For example, in the fully folded state of Figure 10c , the decorative members 113 and 114 can be spaced apart from the center protrusion 223 at a third distance d3.

[0139] In an embodiment, the first distance d1 can be greater than the second distance d2 and the third distance d3. The second distance d2 can be greater than the third distance d3. In various embodiments, when the electronic device 100 is folded, the first housing 111 (e.g., the first decorative member 113) and the second housing 112 (e.g., the second decorative member 114) can move toward the center protrusion 223 (or the folding axis F).

[0140] In the folding operation, the support part 232 of the moving part 230 can press the fixed part 210 by the operation of the housings 111 and 112 (e.g., the first decorative member 113 and the second decorative member 114). At this time, a reaction force generated by the fixed part 210 fixed to the hinge housing 119 can be applied to the moving part 230. The reaction force can move the moving part 230 in a direction away from the center protrusion 223. For example, the support part 232 of the moving part 230 can press the guide rail 211 of the fixed part 210, and the support part 232 of the moving part 230 can be pressed in a direction away from the center protrusion 223 by the reaction force against the pressing.

[0141] In an embodiment, when the electronic device 100 moves from the fully folded state to the flat state, the distance between the central protrusion 223 and the housings 111 and 112 (e.g., the first and second decorative members 113 and 114) may increase (d3->d2->d1), and the pressure applied from the fixed part 210 to the movable part 230 may be released. At this time, the elastic member 258 may apply an elastic force to the movable part 230, causing the movable part 230 to move in a direction toward the central protrusion 223 (or the folding axis F).

[0142] The protective structure 200 disclosed in the present disclosure may include a moving part 230 that moves using mechanical movement that occurs during the folding and unfolding operations of the foldable electronic device 100. Therefore, the protective structure 200 can protect the folding area 123 by covering the edge of the folding area 123 in a flat state and does not collide with the folding area 123 during the folding operation.

[0143] Figure 11a 、 Figure 11b and Figure 11c is a view illustrating a guide groove of a protection structure of an electronic device according to an embodiment.

[0144] In an embodiment, each of the guide grooves 253 of the guide member 250 may include a first end 253-1 relatively close to the folding axis F and a second end 253-2 relatively far from the folding axis F. In an embodiment, the guide protrusion 234 may be movable between the first end 253-1 and the second end 253-2.

[0145] For example, when the electronic device 100 moves from the flat state to the folded state, the guide protrusion 234 of the moving member 230 may move from the first end 253-1 toward the second end 253-2. When the electronic device 100 moves from the folded state to the flat state, the guide protrusion 234 may move from the second end 253-2 toward the first end 253-1.

[0146] In the illustrated embodiment, in the flat state, the guide protrusion 234 may be located in the first end 253-1. In the folded state, the guide protrusion 234 may be located at a position spaced apart from the first end 253-1 compared to when the electronic device 100 is in the flat state. In the fully folded state, the guide protrusion 234 may be closer to the second end 253-2 than in the folded state and the flat state.

[0147] In an embodiment, in the fully folded state, the guide protrusion 234 may be located in a position spaced apart from the second end portion 253 - 2 by a predetermined interval d.

[0148] For example, when the electronic device 100 is in a fully folded state, the main impact force P may be applied to the fixed component 210. The unfixed movable component 230 may be moved by the impact force P in the direction of the impact force (e.g., relative to the direction of the impact force). Figure 11c Since the guide protrusion 234 moves in the upper direction of the guide groove 253, the guide protrusion 234 may collide with the second end 253-2 of the guide groove 253. This collision may damage the guide groove 253 and the guide protrusion 234. Therefore, the protective structure 200 according to the embodiment disclosed in the present disclosure can be formed so that when fully folded, the guide protrusion 234 of the movable member 230 and the end (e.g., the second end 253-2) of the guide groove 253 of the guide member 250 are spaced apart by a predetermined distance. Therefore, the guide protrusion 234 can be prevented from colliding with the guide member 250.
