The second housing 120 may be formed of the same material as the first housing 110. The second housing 120 may be arranged to be horizontally or vertically symmetrical to the first housing 110, and the remaining area of the screen 160 (e.g., a bottom portion 162 of the screen 160 and an opposite side of the central part 163 thereof) except the area disposed on the first housing 110 can be disposed on a front side of the second housing 120. At least part of the second housing 120 can be joined to the lower part 162 of the screen 160 Alternatively, a periphery of the front side of the second housing 120 can be joined to a periphery of the bottom part 162 of the screen 160. In another case, one side of a bottom part of the front side of the second housing 120 can be joined to one side of the bottom portion 162 of fabric 160. In this regard, a second layer of adhesive 167b may be disposed in at least a partial area between the second housing 120 and the bottom portion 162 of fabric 160. Similar to the first housing 110, the second housing 120 may have a void therein, or may be coupled to the second cover 129 to form a void. Electronic components used to drive the screen 160 can be disposed in the void.

For example, as illustrated in Figure 1A, when the first housing 110 and the second housing 120 are arranged side by side, the hinge housing 150 can be hidden by the first housing 110 and the second housing 120. As shown in Fig. 1B , when one side of the first housing 110 and one side of the second housing 120 face each other, at least part of the hinge housing 150 may be exposed to the outside between an edge of the first housing 110 and an edge of the second housing 120 (e.g. example, the edges of the first housing 110 and the second housing 120 facing each other in a flat state).

[035] According to various embodiments, at least part of the screen 160 may be flexible. According to one embodiment, the screen 160 can include the upper part 161 or the first area that is disposed over the first housing 110, the lower part 162 or the second area that is disposed over the second housing 120, and the central part 163 or the central area to which the first housing 110 and second housing 120 are adjacent. In various embodiments, the entire screen 160 may have flexibility. Alternatively, at least part of the central portion 163 of the screen 160 may be flexible. The central part 163 of the screen 160 can be arranged in such a way that the first housing 110 and the second housing 120 are not joined thereto. For example, center portion 163 of screen 160 can be arranged to be spaced from the front sides of first housing 110 and second housing 120 at a predetermined interval. The upper part 161 of the fabric 160 can be bonded to at least part of the first housing 110, and the lower part 162 of the fabric 160 can be bonded to at least part of the second housing 120. In this regard, the first layer of adhesive 167a can be disposed in at least a partial area between the screen 160 and the first housing 110, and the second adhesive layer 167b can be disposed in at least a partial area between the screen 160 and the second housing 120. The first adhesive layer 167a and the second layer of adhesive 167b can be disposed only on the periphery of the first housing 110 and the second housing 120.

For example, the bottom surface of the fixed support 213 can be shaped to match the shape of the interior of the pivot housing 150. An upper surface (e.g., a surface facing the z-axis direction) of the fixed support 213 can have a flat shape, and rail slots 213a and 213b to which the rotatable supports 211 and 212 are attached may be formed in the upper surface of the fixed support 213. According to one embodiment, the fixed support 213 may have a cross-section, of which at least part is constructed with an arc shape from the top surface (for example, the surface facing the z-axis direction) to the bottom surface (for example, the surface facing the z-axis direction), and the fixed support 213 may include the first rail slot 213a into which a first rail 211_3 of the first rotatable support 211 is inserted in a second direction (e.g. the y-axis direction) from a first direction (e.g. , the y-axis direction). According to one embodiment, the fixed support 213 can have a cross-section, at least part of which is constructed with an arc shape towards the upper surface (e.g. the surface facing the z-axis direction) towards the bottom surface (e.g., the surface facing the z-axis direction), and the fixed support 213 may include the second rail slot 213b into which a second rail 212_3 of the second rotatable support 212 is inserted in the first direction (e.g., , the y-axis direction) from the second direction (for example, the y-axis direction). The first rail slot 213a may be located to be biased in the y-axis direction compared to the second rail slot 213b. The second rail slot 213b may be arranged to be biased in the y-axis direction compared to the first rail slot 213a. The first rail slot 213a can rotate about the first virtual axis 11, and the second rail slot 213b can rotate about the second virtual axis 12. The first virtual axis 11 and the second virtual axis 12 can be formed in the air above the upper surface (e.g., the surface facing the z-axis direction) of the fixed support 213. The first virtual axis 11 and the second virtual axis 12 may be formed spaced apart from each other at an interval specified. According to one embodiment, the fixed support 213 can include a first mounting recess 213_2a and a second mounting recess 213_2b that are formed in a side portion of the fixed support 213 that is disposed in a third direction (for example, the direction of x axis). One end of the first rotatable member 231 (e.g., at least part of a first mounting part 231_3) is mountable in the first mounting recess 213_2a, and one end of the second rotary member 232 (e.g., at least part of a second mounting part 232_3) can be mounted in the second mounting recess 213_2b.

[052] According to various embodiments, the fixed support 213 may include a first fixing hole 213_1a and a second fixing hole 213_1b that are used to fix the fixed support 213 to the hinge housing 150. In the electronic device 100, the support fixture 213 can be secured to pivot housing 150 using mating components (e.g. screws or the like). According to one embodiment, the first fixing hole 213_1a and the second fixing hole 213_1b can be arranged symmetrically on the upper surface (for example, the surface facing the z-axis direction) of the fixed support 213 in a diagonal direction to more firmly and stably attach the fixed bracket 213 to the pivot housing 150.

[053] The first rotatable support 211 may include a first support body 211_1, a first sliding hole 211_2 formed at one end (for example, an end facing the x axis direction) of the first support body 211_1, the first rail 211_3 formed at an opposite end (e.g., an end facing the y-axis direction) of the first support body 211_1, and first housing coupling holes 211_4 used to couple the first rotatable support 211 to the first housing 110.

[054] The first support body 211_1 can be constructed in a complete “L” shape. An upper surface (e.g., a surface disposed facing the z-axis direction) of the first support body 211_1 may be formed to be flat. Referring to the illustrated drawing, the first sliding hole 211_2 can be disposed at a right end (e.g., an end facing the x-axis direction) of the first support body 211_1 in a downward direction (e.g., the z-axis direction), and the first rail 211_3 may be disposed on a lower surface (e.g., a surface facing the z-axis direction) at the opposite end (e.g., the end facing the z-axis direction) y) of the first support body 211_1.

[055] The first sliding hole 211_2 can be arranged at one end (for example, the end facing the x axis direction) of the first support body 211_1 and can be arranged at the bottom of the first support body 211_1. The first slide hole 211_2 may be formed to be larger in the first direction (eg, the y-axis direction) than in the third direction (eg, the x-axis direction). Therefore, the first fastening part 251 inserted in the first slide hole 211_2 can slide in the first slide hole 211_2 in either the first direction (e.g., the y-axis direction) and the second direction (e.g., the y-axis direction). y-axis direction).

The first rail 211_3 may have an arc shape with a predetermined internal angle. The first rail 211_3 can be inserted into the first rail slot 213a formed in the fixed support 213 and can rotate through a specified range of angles along the first rail slot 213a. According to one embodiment, the first rail 211_3 can rotate, for example, in the range of -10 degrees to 100 degrees (or 0 degrees to 90 degrees). The first rail 211_3 is rotatable between the y axis and the z axis around the first virtual axis 11 formed by the first rail slot 213a.

In the illustrated drawing, it is exemplified that two first housing coupling holes 211_4 are formed in the first support body 211_1. However, revelation is not limited to this. Coupling members can secure the first rotatable support 211 to the first housing 110 by being coupled with bosses on the first housing 110 while being secured to the first housing coupling holes 211_4.

[059] The second support body 212_1 can have substantially the same shape as the first support body 211_1. Therefore, an upper surface (e.g., a surface disposed facing the z-axis direction) of the second support body 212_1 can be formed to be flat.

[060] The second sliding hole 212_2 can be arranged at a right end (for example, an end facing the x axis direction) of the second support body 212_1 and can be arranged at the bottom of the second support body 212_1 . The second slide hole 212_2 can be arranged to be symmetrical to the first slide hole 211_2 with respect to the fixed support 213. The second slide hole 212_2 can have the same shape as the first slide hole 211_2.

[061] The second rail 212_3 can be arranged at the opposite end of the second support body 212_1 facing the first direction (for example, the end facing the y axis direction) and can be arranged at the bottom of the second body of support 212_1. The second rail 212_3 can be substantially the same shape as the first rail 211_3 and can be inserted into the second rail slot 213b. The second rail 212_3 can rotate about the second virtual axis 12 in a specified range of angles, for example in the range 80 degrees to 190 degrees (or 90 degrees to 180 degrees). For example, the second rail 212_3 can perform rotary movement in the range between the y-axis and the z-axis.

[062] The second housing coupling holes 212_4 can be formed adjacent to an edge of the second support body 212_1 (for example, an edge facing the y axis direction) and can be formed through the upper surface (for example , the surface facing the z-axis direction) and the bottom surface (e.g., the surface facing the z-axis direction) of the second support body 212_1.

The first fastening part 251 can be formed to be greater than at least the sum of the length of the first sliding hole 211_2 and the length of the first connection part 221_2 of the first arm 221. Opposite sides of the first fastening part 251 can be fastened after the first fastening part 251 is inserted into the first sliding hole 211_2 and the first connecting part 221_2. The first fastening part 251 may have a smaller diameter than the first connecting part 221_2.

The first connecting part 221_2 can be disposed on a lower surface (e.g. a surface facing the z axis direction) of an upper edge part (e.g. an end part facing the y axis direction ) of the first basic body 221_1. The first connection part 221_2 may include a hole that is drilled in the fourth direction (eg the x-axis direction). The first fastening part 251 can be fixedly mounted on the first connecting part 221_2.

[067] The first insert part 221_3 can be disposed on a bottom surface (for example, a surface facing the z axis direction) of a lower edge part (for example, an end part facing the z direction) y-axis of the first basic body 221_1. The first insertion part 221_3 may include a hole that is drilled in the fourth direction (e.g., the x axis direction) and that has an at least partially angled cross section. At least part of the first rotatable member 231 can be mounted on the first insert part 221_3. The first rotating cam 221_4 can be disposed on one side (e.g., one end facing the x axis direction) of the first insertion part 221_3.

[068] The first rotary cam 221_4 may include at least one ridge and valley disposed in the direction in which the first rotary member 231 is inserted and protrudes from the first insertion part 221_3. According to one embodiment, the ridge and valley may include, at one end thereof, a flat area of a predetermined length. Therefore, while the first rotating cam 221_4 rotates in a state of being engaged with a fixed first cam 241_1a of the cam portion 241, a section in which a ridge end of the first rotating cam 221_4 is brought into contact with an end of a ridge of the first fixed cam 241_1a can be formed to a specified width. In the case where the section in which the ridge end of the first rotating cam 221_4 is brought into contact with the ridge end of the first fixed cam 241_1a is formed by the specified width, an assembly state of the first housing 110 and the second housing 120 in a predetermined angle in the corresponding section can be held more firmly, and assembly states in various angle ranges can be provided.

The first shaft body 231_1 may be coupled to the first rotary cam 221_4 and may have a cross section angled in the y-axis direction for rotating the first rotary cam 221_4 while being rotated by external pressure. For example, the first axis body 231_1 may include a plurality of surfaces that are planar in the length direction (e.g., in the x-axis direction or in the x-axis direction). Correspondingly, the inner wall of the first insertion part 221_3, on which the first rotating cam 221_4 is arranged, can have a shape corresponding to the cross-section of the first shaft body 231_1. The first shaft gear 231_2 can be disposed on the first shaft body 231_1 in order to be biased in the fourth direction (e.g. in the x-axis direction). The first shaft gear 231_2 can be fitted with the first idler gear 233.

At least part of the first mounting part 231_3 can pass through a guide hole formed in the support plate 235 and can be mounted in the first mounting recess 213_2a formed in the fixed support 213. The first fixing part 251 can fix the first rotatable support 211 and the first arm 221, and for this reason the first mounting part 231_3 can be securely attached to the first mounting recess 213_2a to prevent separation or twisting of the first axle body 231_1.

[073] The second rotating member 232 can have one end mounted in the second mounting recess 213_2b formed in the fixed support 213.

With respect to rotation of the first arm 221, at least part of the exterior of the first axle body 231_1 may have an angled shape (e.g., a polygonal cross-sectional shape or a shape including a plurality of faces). The first axle body 231_1 may have, in an end part thereof (e.g. an end part on the side opposite the first mounting part 231_3), a first fastening groove 231_1a in which a fastening clip (e.g. the fifth fixing clip 249_1) is inserted to fix the first shaft body 231_1 to the support bracket 243. A second fixing groove 231_1a can be arranged on one side of the first mounting part 231_3, and a fixing clip (for example , the third fastening clip 292_1) can be inserted into the second fastening groove 231_1a to prevent the first mounting part 231_3 inserted and mounted in the first mounting recess 213_2a from being separated from the support plate 235.

[093] Similar to the first rotating member 231, the second rotating member 232 may include the second shaft body 232_1, the second shaft gear 232_2 and the second mounting part 232_3 which are arranged continuously. The second shaft body 232_1 can be provided similar or identical to the first shaft body 231_1. The second axle body 232_1 may have, in an end part thereof (e.g. an end part on the opposite side to the second mounting part 232_3), a third fastening groove 232_1a in which a fastening clip (e.g. the sixth fixing clip 249_2) is inserted to fix the second shaft body 232_1 to the support bracket 243. A fourth fixing groove 232_3a can be arranged on one side of the second mounting part 232_3, and a fixing clip (for example , the fourth mounting clip 292_2) can be inserted into the fourth mounting slot 232_3a to prevent the second mounting part 232_3 inserted and mounted in the second mounting recess 213_2b from being separated from the support plate 235.

[094] The stop 236 may include the stop body 236_1, the first shaft insertion hole 236a and the second shaft insertion hole 236b. The first shaft insertion hole 236a can be disposed between the first arm 221 mounted on the first shaft body 231_1 and the first shaft gear 231_2. The second shaft insertion hole 236b can be disposed between the second arm 222 mounted on the second shaft body 232_1 and the second shaft gear 232_2. The stop body 236_1 may include a first stop 236_2a arranged to support one side 221_1a of the first arm 221 when the electronic device 100 is in a flat state and a second stop 236_2b arranged to support a side 222_1a of the second arm 222 when the electronic device 100 is in the flat state.

Based on the structure of the stop 236 described above, the first arm 221 and the second arm 222 can be supported in order not to rotate further in the directions of rotation in the flat state or in the folded state.

[095] Figure 7 illustrates a view of a first state of some components of the electronic device according to various embodiments.

[096] Referring to figures 1A and 7, some components of the electronic device may include the first hinge structure 200a and the screen 160, and the first hinge structure 200a and the screen 160 may have the first state (for example, a flat state).

[097] As described above, the first pivot structure 200a may include the first rotatable support 211, the second rotatable support 212, the fixed support 213, the first arm 221, the second arm 222, the gear structure 230 including the shaft gears and intermediate gears of the first rotary member 231 and the second rotatable member 232, the cam portion 241, the first elastic body 242a, the second elastic body 242b, the first rotatable member 231, the second rotary member 232 and the support bracket 243. The first swivel bracket 211 can be connected to the first arm 221 by the first fastening part 251. The second swivel bracket 212 can be connected to the second arm 222 by the second fastening part 252.

[098] The screen 160 can remain in a flat state while the first rotatable support 211 and the second rotatable support 212 are maintained in a flat state. The first arm 221 can rotate about the first rotatable member 231 within a specified range of angles. The second arm 222 can rotate about the second rotatable member 232 within the specified range of angles. The first rotatable support 211 can rotate about the first virtual axis 11 within a range of angles that is similar or equal to that of the first arm 221. The second rotatable support 212 can rotate about the second virtual axis 12 within a range of angles that is similar or equal to that of the second arm 222. The first virtual axis 11 may be formed at a higher position than the first rotatable component 231 in the direction towards the screen 160. The second virtual axis 12 may be formed at a higher position than that of the second rotary component 232 in the direction towards the screen 160. The gap between the first virtual axis 11 and the second virtual axis 12 may be less than the gap between the first rotatable component 231 and the second rotatable member 232. According to various embodiments, the first virtual axis 11 and the second virtual axis 12 can be formed side by side on a horizontal axis. According to one embodiment, the first virtual axis 11 and the second virtual axis 12 can be formed at the same height as the screen 160, or can be formed above the screen 160 (e.g., in the air above the screen 160).

[099] The first support body 211_1 of the first rotatable support 211 and the second support body 212_1 of the second rotary support 212 can be arranged side by side while the first rotatable support 211 and the second rotary support 212 are maintained in a flat state . According to one embodiment, the upper surface of the first support body 211_1 and the upper surface of the second support body 212_1 can be arranged identically facing upwards with respect to the illustrated drawing. According to one embodiment, the first arm 221 and the second arm 222 can also be arranged side by side while the first rotatable support 211 and the second rotatable support 212 are maintained in the flat state, and thus both of the first basic body 221_1 of the first arm 221 and the second basic body 222_1 of the second arm 222 can face in the same direction (for example, the upward direction with respect to the illustrated drawing). Therefore, the first support body 211_1, the second support body 212_1, the first basic body 221_1 and the second basic body 222_1 can all be arranged side by side with respect to the horizontal axis and can all be arranged to face the same upward direction as shown in the drawing. The first support body 211_1, the second support body 212_1, the first basic body 221_1 and the second basic body 222_1 can support the rear surface of the screen 160 without a height difference between them.

[0100] According to various embodiments, a predetermined gap Gap_1 can be formed between the central part 163 of the screen 160, which is foldable, and the hinge structures 200a and 200b. A layer of adhesive may be disposed on peripheral areas (e.g., top 161 or bottom 162) except the center portion 163 of screen 160.

[0101] Figure 8 illustrates a view of a first specified angle state of the first hinge structure according to various embodiments.

[0102] Referring to Figures 1A and 8, the first hinge structure 200a may include the first specified angle state. As described above, the first pivot structure 200a may include the first rotatable support 211, the second rotatable support 212, the fixed support 213, the first arm 221, the second arm 222, the gear structure 230, the cam portion 241, the first elastic body 242a, the second elastic body 242b, the first rotatable member 231, the second rotatable member 232 and the support support 243. The first rotatable support 211 can be connected to the first arm 221 by the first fastening part 251 The second rotatable support 212 can be connected to the second arm 222 by the second fastening part 252.

[0103] A first housing (for example, the first housing 110 of Figure 1A) to which the first rotatable support 211 is attached or a second housing (for example, the second housing 120 of Figure 1A) to which the second rotary support 212 is fixed can be rotated through a predetermined angle in the direction of a vertical axis 803 from a point on a horizontal axis 801 relative to the illustrated design by means of external pressure. For example, the first rotatable support 211 connected to the first housing 110 can rotate about the first virtual axis 11 by a first angle (e.g. 30 degrees) in the direction of the vertical axis 803 (e.g. the z axis of the figure 4) from a point on the horizontal axis 801 (for example, the y axis or the y axis of figure 4) (for example, in the direction of the vertical axis 803 from the right with respect to the illustrated drawing ). When the first rotatable support 211 is rotated through the first angle by means of external pressure, the corresponding pressure can be transmitted to the first arm 221 by means of the first clamping part 251. Therefore, the first arm 221 can rotate around the first component rotatable 231 in the first angle in the direction of the vertical axis 803 in the horizontal axis 801. In this operation, the force depending on the rotary movement can be transmitted to the first rotary cam 221_4 and to the first insertion part 221_3. The first rotatable member 231, one side of which is inserted into the first insert part 221_3, can rotate as the first insert part 221_3 rotates, and the first shaft gear 231_2 of the first rotatable member 231 can rotate depending on the rotation of the first rotating member 231. The first idler gear 233 and the second idler gear 234 engaged with each other can rotate depending on the rotation of the first shaft gear 231_2. Consequently, the second shaft gear 232_2 can rotate, and the second rotating member 232 can rotate correspondingly. The second insertion part 222_3 can rotate depending on the rotation of the second rotatable member 232, the second arm 222 can rotate depending on the rotation of the second insertion part 222_3, and the second rotatable support 212 connected to the second arm 222 by the second fixing part 252 can rotate depending on the rotation of the second arm 222.

[0104] As described above, the first pivot structure 200a may have the structure in which the first rotatable support 211 and the second pivotal support 212 are rotated simultaneously by means of external pressure (or force). Therefore, the first rotatable support 211 and the second rotary support 212 can be rotated simultaneously even if external pressure is applied to the second housing 120 to which the second rotary support 212 is connected, or if external pressure is simultaneously applied to the first housing 110 and the second housing 120. As the first housing 110 and the second housing 120 of the electronic disclosure device 100 are rotated simultaneously, twisting of the first housing 110 and the second housing 120 can be suppressed, and precise pivotal movement can be realized.

[0105] According to various embodiments, the ridge of the first rotating cam 221_4 and the ridge of the second rotating cam 222_4 can remain in contact with the adjacency of the top of the ridge of the first fixed cam 241_1a and the adjacency of the top of the ridge of the second fixed cam 241_1b as the first arm 221 and second arm 222 rotate through the first specified angle.

[0106] According to one embodiment, the first virtual geometry axis 11 of the first rotatable support 211 and the second virtual geometry axis 12 of the second rotary support 212 can be arranged between the first rotatable component 231 of the first arm 221 and the second rotary component 232 of the second arm 222, and for this reason the amount of rotation of the first rotary support 211 can differ from the amount of rotation of the first arm 221. Therefore, the upper surface of the first support body 211_1 of the first rotary support 211 can additionally protrude upwards beyond the upper surface of the first basic body 221_1 of the first arm 221 with respect to the horizontal axis 801. As the first rotatable support 211 and the first arm 221 are connected by the first fastening part 251, the first fastening part 251 can slide a predetermined distance along the first slide hole 211_2 of the first rotatable support 211 while the first rotary support 211 rotates. Similarly, the upper surface of the second support body 212_1 can be rotated to further project beyond the second basic body 222_1 with respect to the horizontal axis 801. Also, how the second rotatable support 212 and the second arm 222 are connected by the second fastening part 252, the second fastening part 252 can slide a predetermined distance along the second sliding hole 212_2 of the second rotatable support 212 while the second rotary support 212 rotates.

[0107] Figure 9 illustrates a view of a second state of specified angle of the first hinge structure according to various embodiments.

[0108] Referring to Figures 1A and 9, the first hinge structure 200a may include the second specified angle state. The first pivot structure 200a may include, for example, the first rotatable support 211, the second rotatable support 212, the fixed support 213, the first arm 221, the second arm 222, the gear structure 230, the cam portion 241 , the first elastic body 242a, the second elastic body 242b, the first rotatable member 231, the second rotatable member 232 and the support support 243. The first rotatable support 211 can be connected to the first arm 221 by the first fastening part 251, and the second rotatable support 212 can be connected to the second arm 222 by the second fastening part 252.

[0109] A first housing (for example, the first housing 110 of figure 1A) or a second housing (for example, the second housing 120 of figure 1A) can be rotated by a second angle (for example, 60 degrees) in the direction of the vertical axis 803 from a point on the horizontal axis 801 relative to the illustrated drawing by means of external pressure (or force). For example, when external pressure or force is transmitted to the first housing 110 or the second housing 120, the first rotatable support 211 or the second rotary support 212 can rotate about the first virtual axis 11 or the second virtual axis 12 at the second angle (e.g., 60 degrees) in the vertical axis direction 803 from a point on the horizontal axis 801 (e.g., in the vertical axis direction 803 from the right with respect to the illustrated drawing). In the process of carrying out the operation described above, the applied force can be mutually transmitted by means of the first arm 221 or the second arm 222, the first rotating member 231, the second rotating member 232 and gear structures 230, and the first support rotatable 211, the second rotatable support 212, the first arm 221 and the second arm 222 can rotate simultaneously.

[0110] When the first rotatable support 211 and the second rotatable support 212 rotate at the second angle, the first fixing part 251 and the second fixing part 252 can slide closer to the fixed support 213 in the first sliding hole 211_2 and in the second sliding hole 212_2 than when the first rotatable support 211 and the second rotary support 212 rotate through the first angle. In the operation process indicated above, the first rail 211_3 of the first rotatable support 211 can rotate away from the center of the fixed support 213 to the right with respect to the illustrated drawing, and the second rail 212_3 of the second rotatable support 212 can rotate away from the center of the fixed support 213 to the left with respect to the illustrated drawing. As the rotational axes of the first rotatable support 211 and the first arm 221 differ from each other and the rotational axes of the second rotary support 212 and the second arm 222 differ from each other, the distance between the upper surface of the first body support 211_1 and the upper surface of the second support body 212_1 can be shaped to be less than the distance between the upper surface of the first basic body 221_1 and the upper surface of the second basic body 222_1 with an approach to the fixed support 213.

[0111] Figure 10 illustrates a view of a second state of some structures of the electronic device according to various embodiments.

[0112] Referring to Figures 1A and 10, the electronic device 100 may include the first hinge structure 200a and the screen 160. The second state of the first hinge structure 200a may include a folded state. The first pivot structure 200a may include, for example, the fixed support 213, the first rotatable support 211, the second pivotal support 212, the first arm 221, the second arm 222, the first fastening part 251, the second attachment 252, the first rotatable member 231, the second rotatable member 232, the gear structure 230 including the shaft gears of the first rotatable member 231 and the second rotatable member 232, the first elastic body 242a, the second elastic body 242b and the support bracket 243.

[0113] In the structure described above, the first rotatable support 211 and the second rotatable support 212 can be arranged to face each other. As the edges of the first housing 110 and the second housing 120 are located adjacent to each other with respect to the illustrated drawing, the first rotatable support 211 can rotate around the first virtual axis 11 and can be tilted to the left at a specified angle with respect to the vertical axis 803 in the illustrated drawing. Furthermore, the second rotatable support 212 can rotate about the second virtual axis 12 and can be tilted to the right at the specified angle with respect to the vertical axis 803. The first virtual axis 11 can be the central axis of rotation of the first rail 211_3, and the second virtual axis 12 may be the central axis of rotation of the second rail 212_3. The first arm 221 can pivot around the first rotatable member 231 and can be located side by side with the first rotatable support 211, and the second arm 222 can pivot around the second rotatable member 232 and can be located side by side with the second rotatable support 212. Therefore, the central part of the screen 160 can be bent into a "U" shape, and the remaining area can be kept in a flat state.

[0114] As the first rotary support 211 and the first arm 221 are located vertically (or inclined to the left at the specified angle with respect to the vertical axis 803), the upper surface of the first support body 211_1 of the first rotary support 211 and the upper surface of the first basic body 221_1 of the first arm 221 can be arranged side by side without a difference in height therebetween. Because of the difference in length between the first swivel bracket 211 and the first arm 221, the first attachment portion 251 can be located at the lower edge of the first slide hole 211_2 of the first swivel bracket 211. When the electronic device 100 is in a flat state, the first fastening part 251 can be located at the upper edge of the first sliding hole 211_2 of the first rotatable support 211. Similarly, when the electronic device 100 is in a folded state, the second fastening part 252 can be located on the lower edge of the second slide hole 212_2.

[0115] The first rotatable support 211 can rotate out of the central part of the fixed support 213 to the right with respect to the illustrated drawing while the electronic device 100 is changed from a first state to a second state (for example, a folded state), and the first rotatable support 211 can rotate towards the right side of the fixed support 213 towards the central part thereof with respect to the illustrated drawing while the electronic device 100 is changed from the second state to the first state (e.g. a flat state) . According to one embodiment, the second rotatable support 212 can pivot away from the central part of the fixed support 213 to the left with respect to the illustrated drawing while the electronic device 100 is changed from the first state to the second state (e.g. a folded state ), and the second rotatable support 212 can rotate towards the left side of the fixed support 213 towards the central part thereof with respect to the illustrated drawing while the electronic device 100 is changed from the second state to the first state (for example, a state flat).

When the electronic device 100 is in a flat state, the first side portion 158a of the housing housing 150 can be received in the first receiving slot 221_9, and the second side portion 158b of the hinge housing 150 can be received in the second receiving slot 222_9.

[0147] According to various embodiments, as the ends of the side parts 158a and 158b of the hinge housing 150 are formed in higher positions than the ends of the first housing 110 and the second housing 120 by the height specified in the axis direction vertical 803, the third and fourth receiving grooves 211_9 and 212_9 can be arranged on the first rotatable support 211 and on the second rotary support 212. The third receiving groove 211_9 can be formed in a central part of the first rotary support 211 (e.g., between the first rail 211_3 and the first housing coupling holes 211_4 illustrated in figure 4). Similarly, the fourth receiving groove 212_9 can be formed in a central part of the second rotatable support 212 (for example, between the second rail 212_3 and the second housing coupling holes 212_4 illustrated in Fig. 4). When the electronic device 100 is in the flat state, the first side part 158a can be received in the third receiving slot 211_9, and the second side part 158b can be received in the fourth receiving slot 212_9.

[0148] According to the use of the structure described above, the heights of the side parts 158a and 158b of the articulation housing 150 in the direction of the vertical axis 803 may be greater than the depths of the first housing 110 and the second housing 120 in the direction opposite to the direction of the vertical axis 803. For example, when the electronic device 100 is in the folded state, the first side portion 158a may be located within the first housing 110 and may be disposed at a higher position than the lower end of the first housing 110, and when viewed in the direction of the horizontal axis 801 at least part of the first side portion 158a may overlap the end of the first housing 110. Similarly, when the electronic device 100 is in the folded state, the second side portion 158b can be located within the second housing 120 and can be disposed in a higher position than the lower end of the second housing 120, and when viewed in the direction of the horizontal axis 801 at least part of the second side portion 158b can overlap the end of the second housing 120.
