[0033] The following discussion of background art is not an admission that any of the art FIGS. 1A-15 The various embodiments described in this patent document are presented only as examples and not in limitation of the principles of the disclosure. One skilled in the art will understand that the principles of the disclosure can be implemented in any suitably arranged system or device.

[0034] In the following, various embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the present disclosure is not limited to the specific embodiments, but includes various modifications, equivalents, and / or alternatives of the embodiments of the present disclosure. In the description of the drawings, like reference numerals can be used to refer to like elements.

[0035] In the disclosure, the expressions "have," "may have," "include," and "comprise," or "may include" and "may comprise" indicate the presence of the corresponding features (for example, such as numerical values, functions, operations, or components) and do not exclude the presence of other features.

[0036] In the disclosure, the expressions "A or B," "at least one of A or / and B," or "one or more of A or / and B," and the like, can include all possible combinations of the items enumerated together. For example, "A or B," "at least one of A and B," or "at least one of A or B," can refer to all of the following cases: (1) including at least one A; (2) including at least one B; or (3) including both at least one A and at least one B.

[0037] As used in various embodiments, such as "first" and "second," or "1st" and "2nd," terms can be used to simply distinguish a corresponding component from another, and do not otherwise limit the component (for example, importance and / or order). For example, "a first user device" and "a second user device" indicate different user devices, regardless of order or priority. For example, without departing from the scope of the disclosure, a first element can be referred to as a second element, and similarly, a second element can be referred to as a first element.

[0038] It will be understood that when an element (for example, a first element) is referred to as being "(operatively or communicatively) coupled with / to" or "connected to" another element (for example, a second element), it can be directly coupled / directly coupled to or directly connected to the other element, or coupled / coupled to or connected to the other element via an intermediate element (for example, a third element). In contrast, when an element (for example, a first element) is referred to as being "directly coupled or directly coupled to" another element (for example, a second element) or "directly connected to" the other element (for example, a second element), it is understood that there is no intermediate element (for example, a third element) between the element and the other element.

[0039] According to circumstances, the term "configured to" used in the disclosure can be used interchangeably with the terms "adapted to", "capable of", "designed to", "suitable for", "to serve for", or "to be able to". The term "configured to" cannot be expressed as "designed to" in hardware only. Instead, the device "configured to" can mean that the device "is able to" operate with another device or other components. For example, "a processor configured to (set to) perform A, B, and C" can refer to, for example, but not limited to, a dedicated processor (e.g., an embedded processor) for performing the corresponding operations or a general-purpose processor (e.g., a central processing unit (CPU) or an application processor) for performing the corresponding operations by executing one or more software programs stored in a storage device.

[0040] The terms used in the disclosure are used to describe the specified embodiments, and are not intended to limit the scope of other embodiments. Unless otherwise stated, the singular form can include the plural form. Unless otherwise defined herein, all terms used herein, including technical terms or scientific terms, can have the same meaning as commonly understood by a person skilled in the art. It will be further understood that, unless explicitly defined in the various embodiments of the disclosure, terms defined in a dictionary and commonly used should also be interpreted as the convention in the relevant art, rather than in an idealized or overly formal manner.

[0044] Referring to FIG. 1A and FIG. 1B , an electronic device 100 (or foldable electronic device) according to an embodiment can include a housing 101 including a first housing 110 and a second housing 120, a display 160 (e.g., a flexible display), and a hinge housing 150 having a hinge structure 200 disposed inside thereof. FIG. 1A FIG. 1 illustrates a perspective view of an electronic device 100 in a first state (e.g., a flat state or an unfolded state), FIG. 1B is a perspective view of the electronic device 100 in a second state (e.g., a folded state). Additionally or alternatively, the electronic device 100 can further include a first cover 119 covering a rear side of the first housing 110 and a second cover 129 covering a rear side of the second housing 120.

[0045] According to various embodiments, the first housing 110 can be disposed to be continuous with the second housing 120 (e.g., when a central portion 163 of the display 160 is unfolded to be flat or when the housing 101 is in a flat state), or can be disposed side by side with the second housing 120, according to the arrangement. Or, when the central portion 163 of the display 160 is folded, a side of the first housing 110 can be disposed to face a side of the second housing 120.

[0046] For example, at least a portion of the first housing 110 can be made of a metallic material, or at least a portion of the first housing 110 can be made of a non-metallic material. For example, the first housing 110 can be made of a material having a predetermined rigidity to support at least a portion of the display 160. One area of the display 160 (e.g., a portion of the upper portion 161 and the central portion 163 of the display 160) can be disposed on at least a portion of the front side of the first housing 110. At least a portion of the first housing 110 can be combined with the upper portion 161 of the display 160. Alternatively, at least a portion of the periphery of the front side of the first housing 110 can be combined with the periphery of the upper portion 161 of the display 160. In another case, one side of the upper portion of the front side of the first housing 110 can be combined with one side of the upper portion 161 of the display 160. In this regard, the first adhesive layer 167a can be disposed in at least a partial area between the first housing 110 and the upper portion 161 of the display 160. The first housing 110 can have an empty space therein, or can also be connected with the first cover 119 to form an empty space inside thereof. Electronic components (e.g., a printed circuit board and components such as at least one processor, at least one memory, and a battery mounted on the printed circuit board) for driving the display 160 can be disposed in the empty space.

[0047] According to various embodiments, edges (e.g., the remaining three edges other than the edge facing the second housing 120) of the first housing 110 can protrude a certain height above the bottom surface of the central portion of the first housing 110 to surround at least one edge of the display 160. Alternatively, a side wall can be disposed at at least one edge of the first housing 110 to face at least one edge of the display 160. For example, a side wall can be formed on the remaining three edges of the first housing 110 other than the edge facing the second housing 120 to have a specified height. The edge portion of the first housing 110 facing the second housing 120 can include a recess, at least a portion of which has a predetermined curvature, such that at least a portion of the hinge housing 150 is disposed therein. For example, the first housing 110 can include a first step 111 in which a portion of the hinge housing 150 on which the first hinge structure 200a is mounted is accommodated, and a second step 112 in which a portion of the hinge housing 150 on which the second hinge structure 200b is mounted is accommodated, on the edge portion facing the second housing 120.

[0048] According to various embodiments, the second housing 120 can be disposed side by side with the first housing 110, or can be disposed such that at least one side thereof faces a side (e.g., a side on which the display 160 is disposed) of the first housing 110. The second housing 120 can be made of the same material as the first housing 110. The second housing 120 can be disposed to be horizontally or vertically symmetrical with the first housing 110, and a remaining area of the display 160 except for an area disposed on the first housing 110 (opposite sides of the lower portion 162 and the central portion 163 of the display 160) can be disposed on a front side of the second housing 120. At least a portion of the second housing 120 can be combined with the lower portion 162 of the display 160. Alternatively, a periphery of the front side of the second housing 120 can be combined with a periphery of the lower portion 162 of the display 160. In another case, one side of a portion of the front side of the second housing 120 can be combined with one side of the lower portion 162 of the display 160. In this regard, the second adhesive layer 167b can be disposed in at least a partial area between the second housing 120 and the lower portion 162 of the display 160. Similar to the first housing 110, the second housing 120 can have an empty space therein, or can be connected with the second cover 129 to form an empty space. Electronic components for driving the display 160 can be disposed in the empty space.

[0049] According to various embodiments, edges (e.g., remaining three edges except for an edge facing the first housing 110) of the second housing 120 can protrude above a bottom surface of a central portion of the second housing 120 by a specified height to surround opposite edges of the display 160. Alternatively, similar to the side wall formed on the first housing 110, a side wall can be disposed on at least one edge of the second housing 120 to face at least one edge of the display 160. For example, a side wall can be formed on remaining three edges of the second housing 120 except for an edge facing the first housing 110 to have a specified height.

[0050] An edge portion of the second housing 120 facing the first housing 110 can include a recess, at least a portion of which has a predetermined curvature such that at least a portion of the hinge housing 150 is disposed therein. For example, the second housing 120 can include a third step 121 in which a portion of the hinge housing 150 on which the first hinge structure 200a is mounted is accommodated, and a fourth step 122 in which a portion of the hinge housing 150 on which the second hinge structure 200b is mounted is accommodated, on the edge portion facing the first housing 110.

[0051] According to various embodiments, the electronic device 100 can include at least one sensor disposed on one side of the first housing 110 or the second housing 120 and related to the operation of a specific function of the electronic device 100.

[0052] According to various embodiments, the hinge housing 150 can be hidden by one side of the first housing 110 and one side of the second housing 120 (e.g., in the flat state of the housing 101) or can be exposed to the outside (e.g., in the folded state of the housing 101), depending on the folded or flat state of the electronic device 100. For example, as shown in FIG. 1A When the first housing 110 and the second housing 120 are disposed 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 a portion of the hinge housing 150 can be exposed to the outside from between one edge of the first housing 110 and one edge of the second housing 120 (e.g., edges of the first housing 110 and the second housing 120 facing each other in the flat state).

[0053] According to various embodiments, at least a portion of the display 160 can be flexible. According to an embodiment, the display 160 can include an upper portion 161 or a first area disposed on the first housing 110, a lower portion 162 or a second area disposed on the second housing 120, and a central portion 163 or a central area adjoining the first housing 110 and the second housing 120. According to various embodiments, the entire display 160 can have flexibility. Alternatively, at least a portion of the central portion 163 of the display 160 can be flexible. The central portion 163 of the display 160 can be disposed such that the first housing 110 and the second housing 120 are not combined therewith. For example, the central portion 163 of the display 160 can be disposed to be spaced apart from the front sides of the first housing 110 and the second housing 120 by a predetermined interval. The upper portion 161 of the display 160 can be combined with at least a portion of the first housing 110, and the lower portion 162 of the display 160 can be combined with at least a portion of the second housing 120. In this regard, a first adhesive layer 167a can be disposed in at least a partial area between the display 160 and the first housing 110, and a second adhesive layer 167b can be disposed in at least a partial area between the display 160 and the second housing 120. The first adhesive layer 167a and the second adhesive layer 167b can be disposed only on the periphery of the first housing 110 and the second housing 120.

When the first housing 110 rotates, the gear structure 230 can transmit a force to allow the second housing 120 to rotate together. In this regard, the gear structure 230 can include a plurality of pinions and idlers.

[0064] The brake support structure 240 can be fixed to the inside of the hinge housing 150 and can provide a designated pressure to the arm brake structure 220. In this regard, the brake support structure 240 can include at least one elastic body and can push the cam portion 241 toward the arm brake structure 220 based on the elastic force of the elastic body, and the cam portion 241 can support cam operation when engaged with the rotating cam structure of the arm brake structure 220.

[0065] As described above, the hinge structure 200a or 200b according to an embodiment can include a bracket structure 210 coupled with the hinge housing 150 and the housings 110 and 120 and supporting folding or unfolding of the display 160 placed thereon, an arm brake structure 220 connected to the bracket structure 210 and providing a dynamic feeling, a gear structure 230 supporting simultaneous operation of the first housing 110 and the second housing 120, and a brake support structure 240 supporting the arm brake structure 220 and having a shaft of the gear structure 230 fixed thereto. The hinge structure 200a or 200b can achieve folding or unfolding of the display 160 by rotating about a virtual shaft formed above the surface of the bracket structure 210. The hinge structure 200a or 200b can provide a dynamic feeling based on a cam structure and can support simultaneous hinge movement of the housings 110 and 120 based on the gear structure 230 to suppress twisting of the housings 110 and 120. Further, the hinge structure 200a or 200b can not only support a flat state or a folded state of the housings 110 and 120, but also support an installation state at a designated angle (e.g., 30 degrees or 60 degrees) (e.g., an angle between the front side of the first housing 110 and the front side of the second housing 120).

[0066] FIG. 4 An exploded perspective view of a hinge structure is illustrated. FIG. 3

[0067] In the following description, a first hinge structure of the hinge structures 200a and 200b will be described by way of example. Reference will be made below to FIG. 4 The first hinge structure 200a described below can have the same structure and configuration as the second hinge structure 200b described above.

At least a part of the aforementioned components of the first hinge structure 200a can be made of a metal material having a predetermined rigidity. Alternatively, the first hinge structure 200a can also be made of a material such as reinforced plastic, resin, or the like, as necessary.

[0069] At least a portion of the shape of the lower surface (e.g., a surface facing the -z-axis direction) of the fixed bracket 213 can include a curved surface. For example, the lower surface of the fixed bracket 213 can be formed to correspond to the shape of the inside of the hinge housing 150. The upper surface (e.g., a surface facing the z-axis direction) of the fixed bracket 213 can have a flat shape, and guide grooves 213a and 213b coupled with the rotation brackets 211 and 212 can be formed on the upper surface of the fixed bracket 213. According to an embodiment, the fixed bracket 213 can have a cross-section of which at least a portion forms a circular arc shape in a direction from the upper surface (e.g., a surface facing the z-axis direction) to the lower surface (e.g., a surface facing the -z-axis direction), the fixed bracket 213 can include a first guide groove 213a into which the first rail 211_3 of the first rotation bracket 211 is inserted in a second direction (e.g., a -y-axis direction), and the fixed bracket 213 can include a second guide groove 213b into which the second rail 212_3 of the second rotation bracket 212 is inserted in a first direction (e.g., a y-axis direction). The first guide groove 213a can be disposed to be offset in the y-axis direction compared to the second guide groove 213b. The second guide groove 213b can be disposed to be offset in the -y-axis direction compared to the first guide groove 213a. The first guide groove 213a can rotate about a first virtual axis 11, and the second guide groove 213b can rotate about a second virtual axis 12. The first virtual axis 11 and the second virtual axis 12 can be formed in a space above the upper surface (e.g., a surface facing the z-axis direction) of the fixed bracket 213. The first virtual axis 11 and the second virtual axis 12 can be formed to be spaced apart from each other at a specified interval. According to an embodiment, the fixed bracket 213 can include a first mounting recess 213_2a and a second mounting recess 213_2b formed on a side portion of the fixed bracket 213 disposed in a third direction (e.g., an x-axis direction). One end (e.g., at least a portion of the first mounting portion 231_3) of the first rotation member 231 can be mounted in the first mounting recess 213_2a, and one end (e.g., at least a portion of the second mounting portion 232_3) of the second rotation member 232 can be mounted in the second mounting recess 213_2b.

[0070] According to various embodiments, the fixing bracket 213 can include a first fixing hole 213_1a and a second fixing hole 213_1b for fixing the fixing bracket 213 to the hinge housing 150. In the electronic device 100, the fixing bracket 213 can be fixed to the hinge housing 150 by using a connecting member (e.g., a screw or the like). According to an embodiment, the first fixing hole 213_1a and the second fixing hole 213_1b can be symmetrically disposed on the upper surface (e.g., a surface facing the z-axis direction) of the fixing bracket 213 in a diagonal direction to more firmly and stably fix the fixing bracket 213 to the hinge housing 150.

[0071] The first rotation bracket 211 can include a first bracket body 211_1, a first sliding hole 211_2 formed at one end (e.g., an end facing the x-axis direction) of the first bracket body 211_1, a first rail 211_3 formed at the opposite end (e.g., an end facing the -y-axis direction) of the first bracket body 211_1, and a first housing connection hole 211_4 for connecting the first rotation bracket 211 with the first housing 110.

[0072] The first bracket body 211_1 can be formed in an overall "L" shape. The upper surface (e.g., a surface disposed to face the z-axis direction) of the first bracket body 211_1 can be formed to be flat. With respect to the illustrated drawings, the first sliding hole 211_2 can be disposed at the right end (e.g., an end facing the x-axis direction) of the first bracket body 211_1 in the downward direction (e.g., the -z-axis direction), and the first rail 211_3 can be disposed on the lower surface (e.g., a surface facing the -z-axis direction) of the opposite end (e.g., an end facing the -y-axis direction) of the first bracket body 211_1.

[0073] The first sliding hole 211_2 can be disposed at one end (e.g., an end facing the x-axis direction) of the first bracket body 211_1 and can be disposed at the bottom of the first bracket body 211_1. The first sliding hole 211_2 can be formed to be longer in the first direction (e.g., the y-axis direction) than in the third direction (e.g., the x-axis direction). Accordingly, the first fixing portion 251 inserted into the first sliding hole 211_2 can slide in the first sliding hole 211_2 in either of the first direction (e.g., the y-axis direction) and the second direction (e.g., the -y-axis). The first sliding hole 211_2 can be disposed to face the fourth direction-facing surface (e.g., a surface disposed to face the -x-axis direction) of the first arm 221. At least a portion of the area of the first sliding hole 211_2 can be aligned with the first connection portion 221_2 of the first arm 221. Accordingly, at least a portion of the first fixing portion 251 can be disposed in the first sliding hole 211_2 and the first connection portion 221_2.

[0074] The first rail 211_3 can be disposed at an opposite end of the first bracket body 211_1 facing the second direction (e.g., one end facing the -y axis direction), and can be disposed at the bottom of the first bracket body 211_1. The first rail 211_3 can be arc-shaped having a predetermined inner angle. The first rail 211_3 can be inserted into the first guide groove 213a formed on the fixed bracket 213, and can rotate within a designated angle range along the first guide groove 213a. According to an embodiment, the first rail 211_3 can rotate, for example, within a range of -10 degrees to 100 degrees (or 0 degrees to 90 degrees). The first rail 211_3 can perform a rotational motion between the y axis and the z axis about the first virtual axis 11 formed by the first guide groove 213a.

[0075] The first housing connection hole 211_4 can be formed adjacent to an edge of the first bracket body 211_1 (e.g., an edge facing the y axis direction), and can be formed through the upper surface (e.g., a surface facing the z axis direction) and the lower surface (e.g., a surface facing the -z axis direction) of the first bracket body 211_1. In the illustrated drawing, it has been exemplified that two first housing connection holes 211_4 are formed in the first bracket body 211_1. However, the disclosure is not limited thereto. The connection member can fix the first rotating bracket 211 to the first housing 110 by being connected with the boss on the first housing 110 when fastened to the first housing connection hole 211_4.

[0076] The second rotating bracket 212 can include a second bracket body 212_1, a second sliding hole 212_2 formed at one end of the second bracket body 212_1 (e.g., one end facing the x axis direction), a second rail 212_3 formed at an opposite end of the second bracket body 212_1 (e.g., one end facing the y axis direction), and a second housing connection hole 212_4 for coupling the second rotating bracket 212 with the second housing 120.

[0077] The second bracket body 212_1 can have substantially the same shape as the first bracket body 211_1. Accordingly, the upper surface (e.g., a surface disposed to face the z axis direction) of the second bracket body 212_1 can be formed flat.

[0078] The second sliding hole 212_2 can be disposed at the right end of the second bracket body 212_1 (e.g., one end facing the x axis direction), and can be disposed at the bottom of the second bracket body 212_1. The second sliding hole 212_2 can be disposed to be symmetrical to the first sliding hole 211_2 with respect to the fixed bracket 213. The second sliding hole 212_2 can have the same shape as the first sliding hole 211_2.

[0079] The second rail 212_3 can be disposed at an opposite end of the second bracket body 212_1 facing the first direction (e.g., an end facing the y-axis direction), and can be disposed at the bottom of the second bracket body 212_1. The second rail 212_3 can have substantially the same shape as the first rail 211_3, and can be inserted into the second rail recess 213b. The second rail 212_3 can rotate within a specified angle range about the second virtual axis 12, for example, within a range of 80 degrees to 190 degrees (or 90 degrees to 180 degrees). For example, the second rail 212_3 can perform a rotational motion within a range between the -y-axis and the z-axis.

[0080] The second housing connection hole 212_4 can be formed adjacent to an edge of the second bracket body 212_1 (e.g., an edge facing the -y-axis direction), and can be formed through the upper surface (e.g., a surface facing the z-axis direction) and the lower surface (e.g., a surface facing the -z-axis direction) of the second bracket body 212_1.

[0081] The first fixing part 251 can have a pin shape having a predetermined length in one direction. The first fixing part 251 can be formed to be longer than 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 fixing part 251 can be fixed after the first fixing part 251 is inserted into the first sliding hole 211_2 and the first connection part 221_2. The first fixing part 251 can have a smaller diameter than the first connection part 221_2. The first fixing part 251 can be located in the first sliding hole 211_2, and can slide in the y-axis direction or the -y-axis direction.

[0082] The second fixing part 252 can have substantially the same shape as the first fixing part 251. The second fixing part 252 can be disposed symmetrically with the first fixing part 251 with respect to the fixing bracket 213, and at least a portion of the second fixing part can be fixedly inserted into the second sliding hole 212_2 and the second connection part 222_2. One side of the second fixing part 252 can slide in the y-axis direction or the -y-axis direction in the second sliding hole 212_2.

[0083] The first arm 221 can be fastened to the first rotating bracket 211 by the first fixing part 251, and can rotate within a specified angle range together with the first rotating bracket 211 during a hinge motion. According to an embodiment, the first arm 221 can include a first base 221_1, a first connection part 221_2, a first insertion part 221_3, and a first rotating cam 221_4.

[0084] An upper surface (e.g., a surface disposed to face the z-axis direction) of the first base 221_1 can be formed flat. The first connecting portion 221_2 can be disposed on a lower surface (e.g., a surface facing the -z-axis direction) of an upper edge portion (e.g., an end portion facing the y-axis direction) of the first base 221_1. The first connecting portion 221_2 can include a hole opened in the fourth direction (e.g., the -x-axis direction). The first fixing portion 251 can be fixedly installed in the first connecting portion 221_2.

[0085] The first insertion portion 221_3 can be disposed on a lower surface (e.g., a surface facing the -z-axis direction) of a lower edge portion (e.g., an end portion facing the -y-axis direction) of the first base 221_1. The first insertion portion 221_3 can include a hole opened in the fourth direction (e.g., the -x-axis direction) and having a cross section at least partially angled. At least a portion of the first rotation member 231 can be installed in the first insertion portion 221_3. The first rotation cam 221_4 can be disposed on one side (e.g., one end facing the x-axis direction) of the first insertion portion 221_3.

[0086] The first rotation cam 221_4 can include at least one ridge and valley disposed in a direction in which the first rotation member 231 is inserted into and protrudes from the first insertion portion 221_3. According to an embodiment, the ridge and valley can include a flat area having a predetermined length at one end thereof. Accordingly, when the first rotation cam 221_4 rotates in a state in which the first rotation cam 221_4 is engaged with the first fixed cam 241_1a of the cam portion 241, a portion in which one end of the ridge of the first rotation cam 221_4 contacts one end of the ridge of the first fixed cam 241_1a can form a designated width. In the case in which the portion in which one end of the ridge of the first rotation cam 221_4 contacts one end of the ridge of the first fixed cam 241_1a forms a designated width, the installed state of the first housing 110 and the second housing 120 at a predetermined angle in the corresponding portion can be more firmly maintained, and an installed state in a variety of angle ranges can be provided.

[0087] The second arm 222 can have substantially the same configuration as the first arm 221. For example, the second arm 222 can include a second base 222_1, a second connecting portion 222_2, a second insertion portion 222_3, and a second rotation cam 222_4. The second base 222_1 can be disposed to be symmetrical to the first base 221_1, and the second connecting portion 222_2 can be fastened to one side of the second fixing portion 252. The second rotation member 232 can be inserted into the second insertion portion 222_3, and the second rotation cam 222_4 can be disposed to be engaged with the second fixed cam 241_1b of the cam portion 241.

[0088] The first rotating member 231 can have one end installed in a first installation recess 213_2a formed on the fixing bracket 213. The first rotating member 231 can be engaged with the first idler gear 233. The first rotating member 231 can be disposed to pass through the stopper 236, the first insertion portion 221_3, the first rotating cam 221_4, the first fixing cam 241_1a of the cam portion 241, and the first elastic body 242a. The first rotating member 231 can be fixed to the support bracket 243. The first rotating member 231 can include a first shaft body 231_1, a first shaft gear 231_2, and a first installation portion 231_3.

[0089] The first shaft body 231_1 can have a length sufficient to pass through the stopper 236, the first insertion portion 221_3, the first rotating cam 221_4, the first fixing cam 241_1a, the first elastic body 242a, and the first support bracket hole 243_2a of the support bracket 243. The first shaft body 231_1 can be connected with the first rotating cam 221_4 and can have an angled cross-section in the y-axis direction to rotate the first rotating cam 221_4 when rotated by external pressure. For example, the first shaft body 231_1 can include a plurality of surfaces flat in the length direction (e.g., the x-axis direction or the -x-axis direction). Accordingly, the inner wall of the first insertion portion 221_3 in which the first rotating cam 221_4 is disposed 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 so as to be biased in the fourth direction (e.g., the -x-axis direction). The first shaft gear 231_2 can be engaged with the first idler gear 233.

[0090] The first installation portion 231_3 can protrude from a surface of the first shaft gear 231_2 facing the fourth direction (e.g., a surface facing the -x-axis direction). At least a portion of the first installation portion 231_3 can pass through the guide hole formed in the support plate 235 and can be installed in the first installation recess 213_2a formed on the fixing bracket 213. The first fixing portion 251 can fix the first rotating bracket 211 and the first arm 221, and thus, the first installation portion 231_3 can be firmly fixed to the first installation recess 213_2a to prevent the first shaft body 231_1 from being separated or twisted.

[0091] One end of the second rotating member 232 can be installed in a second installation recess 213_2b formed on the fixed bracket 213. The second rotating member 232 can be engaged with the second idler 234. The second rotating member 232 can be provided to pass through the stopper 236, the second insertion part 222_3, the second rotation cam 222_4, the second fixed cam 241_1b of the cam part 241, and the second elastic body 242b. The second rotating member 232 can be fixed to the support bracket 243 at the opposite end thereof. The second rotating member 232 can include a second shaft body 232_1, a second shaft gear 232_2, and a second installation part 232_3.

[0092] The length of the second shaft body 232_1 can be sufficient to pass through the stopper 236, the second insertion part 222_3, the second rotation cam 222_4, the second fixed cam 241_1b, the second elastic body 242b, and the second support bracket hole 243_2b of the support bracket 243. The second shaft body 232_1 can have substantially the same shape and size as the first shaft body 231_1. The second shaft body 232_1 can be disposed at a position spaced apart from the first shaft body 231_1 by a predetermined length. The second shaft gear 232_2 can have the same shape and size as the first shaft gear 231_2, and can be disposed on the second shaft body 232_1. The position of the second shaft gear 232_2 can be symmetrical to the position of the first shaft gear 231_2. At least a portion of the second installation part 232_3 can have the same shape and size as the first installation part 231_3, and can be installed in the second installation recess 213_2b. In this process, at least a portion of the second installation part 232_3 can pass through the guide hole of the support plate 235, and can be installed in the second installation recess 213_2b. The second installation part 232_3 can be more firmly installed in the second installation recess 213_2b in the process of fixing the second rotation bracket 212 and the second arm 222 by the second fixing part 252.

[0093] The stopper 236 can support a corresponding pressure to prevent the first arm 221 and the second arm 222 from rotating by a specified angle or more when a pressure that makes the first arm 221 and the second arm 222 exceed the specified angle range is applied. The stopper 236 can include a stopper main body 236_1, a first shaft insertion hole 236a into which the first shaft body 231_1 of the first rotating member 231 is inserted, and a second shaft insertion hole 236b into which the second shaft body 232_1 of the second rotating member 232 is inserted.

[0094] According to various embodiments, the stopper body 236_1 can be formed to further protrude beyond the surfaces of the first shaft insertion hole 236a and the second shaft insertion hole 236b in the third direction (for example, the x-axis direction). The stopper body 236_1 can be disposed to limit the rotation range of one side (for example, the surface of the first insertion portion 221_3 facing the fourth direction (for example, the surface facing the -x-axis direction)) of the first arm 221 when the first arm 221 rotates, and can be disposed to limit the rotation range of one side (for example, the surface of the second insertion portion 222_3 facing the fourth direction (for example, the surface facing the -x-axis direction)) of the second arm 222 when the second arm 222 rotates.

[0095] One side (for example, the surface facing the x-axis direction) of the first shaft insertion hole 236a can be disposed to face the surface of the first insertion portion 221_3 of the first arm 221 facing the fourth direction (for example, the surface facing the -x-axis direction), and one side (for example, the surface facing the x-axis direction) of the second shaft insertion hole 236b can be disposed to face the surface of the second insertion portion 222_3 of the second arm 222 facing the fourth direction (for example, the surface facing the -x-axis direction). The surface of the stopper body 236_1 facing the third direction (for example, the surface facing the x-axis direction) can be disposed to face the surface of the cam body 241_1 of the cam portion 241 facing the fourth direction (for example, the surface facing the -x-axis direction).

[0096] The cam portion 241 can include a cam body 241_1, a first fixed cam 241_1a, a second fixed cam 241_1b, a first cam hole 241_2a, and a second cam hole 241_2b. The cam body 241_1 can have a predetermined length, and the first fixed cam 241_1a and the second fixed cam 241_1b can be disposed at opposite edges of the cam body 241_1. A surface of the cam body 241_1 facing the fourth direction (e.g., a surface facing the -x-axis direction) can be disposed to face a surface of the stopper body 236_1 facing a surface of the third direction (e.g., a surface facing the x-axis direction). The first fixed cam 241_1a can include ridges and valleys disposed in the fourth direction (e.g., the -x-axis direction), and the first cam hole 241_2a through which the first rotating member 231 passes can be formed in the first fixed cam 241_1a. The first fixed cam 241_1a can be engaged with the first rotating cam 221_4. One side of the first elastic body 242a can be in contact with a surface of the first fixed cam 241_1a facing the third direction (e.g., a surface facing the x-axis direction). The second fixed cam 241_1b can be disposed in the same direction as the first fixed cam 241_1a, and can be disposed to be spaced apart from the first fixed cam 241_1a by the length of the cam body 241_1 in the y-axis direction. The second fixed cam 241_1b can be engaged with the second rotating cam 222_4, and the second elastic body 242b can be in contact with a surface of the second fixed cam 241_1b facing the third direction (e.g., a surface facing the x-axis direction). The second cam hole 241_2b through which the second rotating member 232 passes can be formed in the center of the second fixed cam 241_1b.

[0097] According to various embodiments, when the first arm 221 and the second arm 222 rotate within a predetermined angle range, the cam portion 241 can move backward in the third direction (e.g., the x-axis direction) by the first rotating cam 221_4 and the second rotating cam 222_4. When the ridges and valleys of the cam are engaged with each other, the cam portion 241 can move in the fourth direction (e.g., the -x-axis direction) by the elastic force of the first elastic body 242a and the second elastic body 242b to return to the initial position.

[0098] The first elastic body 242a can have a spiral spring shape with an inner empty space. The first shaft body 231_1 of the first rotating member 231 passing through the first fixed cam 241_1a can be inserted into the first elastic body 242a. The first elastic body 242a and the second elastic body 242b can be disposed between the cam part 241 and the support bracket 243, and can function to push the cam part 241 in the fourth direction (for example, -x axis direction) with respect to the fixed support bracket 243. The second elastic body 242b can be disposed to be spaced apart from the first elastic body 242a at a designated interval, and can be disposed to be in contact with a surface (for example, a surface facing the x axis direction) of the second fixed cam 241_1b facing the third direction.

[0099] The support bracket 243 can include a support part 243_1, a first support bracket hole 243_2a, and a second support bracket hole 243_2b. The support part 243_1 can include a through hole 243_1a formed through the support part 243_1 in a vertical direction (for example, -z axis direction from one point on the z axis). The through hole 243_1a can be used to fix the support bracket 243 to the hinge housing 150. The first support bracket hole 243_2a can be disposed to protrude from one side of the support part 243_1, and can support one side of the first elastic body 242a. In addition, one end of the first rotating member 231 can be inserted into the first support bracket hole 243_2a. The second support bracket hole 243_2b can be disposed at a position spaced apart from the first support bracket hole 243_2a by a predetermined distance.

At least a portion of the outside of the first shaft body 231_1 can have an angular shape (for example, a polygonal cross-sectional shape or a shape having a plurality of faces) with respect to the rotation of the first arm 221. The first shaft body 231_1 can have a first fixing groove 231_1a on an end portion thereof (for example, an end portion on the opposite side of the first mounting portion 231_3), into which a fixing clip (for example, a 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 disposed on one side of the first mounting portion 231_3, and a fixing clip (for example, a third fixing clip 292_1) can be inserted into the second fixing groove 231_1a to prevent the first mounting portion 231_3, which is inserted and mounted in the first mounting recess 213_2a, from being separated from the support plate 235.

A fourth fixing groove 232_3a can be disposed on one side of the second mounting portion 232_3, and a fixing clip (for example, a fourth fixing clip 292_2) can be inserted into the fourth fixing groove 232_3a to prevent the second mounting portion 232_3, which is inserted and mounted in the second mounting recess 213_2b, from being separated from the support plate 235.

[0112] The stopper 236 can include a stopper body 236_1, a first shaft insertion hole 236a, and a second shaft insertion hole 236b. The first shaft insertion hole 236a can be disposed between the first shaft gear 231_2 and the first arm 221 mounted on the first shaft body 231_1.

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

[0113] FIG. 7 A view showing a first state of some components of an electronic device according to various embodiments is illustrated.

[0114] Referring to FIG. 1A and FIG. 7 Some components of an electronic device can include a first hinge structure 200a and a display 160, and the first hinge structure 200a and the display 160 can have a first state (e.g., a flat state).

[0115] As described above, the first hinge structure 200a can include a first rotation bracket 211, a second rotation bracket 212, a fixed bracket 213, a first arm 221, a second arm 222, a gear structure 230 including a first rotation member 231 and a second rotation member 232, a cam portion 241, a first elastic body 242a, a second elastic body 242b, the first rotation member 231, the second rotation member 232, and a support bracket 243. The first rotation bracket 211 can be connected with the first arm 221 through a first fixing portion 251. The second rotation bracket 212 can be connected with the second arm 222 through a second fixing portion 252.

[0116] The display 160 can be maintained in a flat state while the first and second rotary brackets 211 and 212 are maintained in a flat state. The first arm 221 can rotate about the first rotary member 231 within a designated angle range. The second arm 222 can rotate about the second rotary member 232 within a designated angle range. The first rotary bracket 211 can rotate about the first virtual axis 11 within an angle range similar to or the same as the angle range of the first arm 221. The second rotary bracket 212 can rotate about the second virtual axis 12 within an angle range similar to or the same as the angle range of the second arm 222. The first virtual axis 11 can be formed at a higher position than the first rotary member 231 in a direction toward the display 160. The second virtual axis 12 can be formed at a higher position than the second rotary member 232 in a direction toward the display 160. The interval between the first virtual axis 11 and the second virtual axis 12 can be shorter than the interval between the first rotary member 231 and the second rotary 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 an embodiment, the first virtual axis 11 and the second virtual axis 12 can be formed at the same height as the display 160, or can be formed above the display 160 (e.g., in the air above the display 160).

[0117] The first bracket body 211_1 of the first rotary bracket 211 and the second bracket body 212_1 of the second rotary bracket 212 can be disposed side by side while the first and second rotary brackets 211 and 212 are maintained in a flat state. According to an embodiment, the upper surface of the first bracket body 211_1 and the upper surface of the second bracket body 212_1 can be disposed to face upward, identically with respect to the shown drawing. According to an embodiment, the first arm 221 and the second arm 222 can also be disposed side by side while the first and second rotary brackets 211 and 212 are maintained in a flat state, and thus the first base body 221_1 of the first arm 221 and the second base body 222_1 of the second arm 222 can both face the same direction (e.g., upward with respect to the shown drawing). Thus, the first bracket body 211_1, the second bracket body 212_1, the first base body 221_1, and the second base body 222_1 can all be disposed side by side with respect to a horizontal axis, and can all be disposed to face the same upward direction with respect to the shown drawing. The first bracket body 211_1, the second bracket body 212_1, the first base body 221_1, and the second base body 222_1 can support the rear surface of the display 160 without a height difference therebetween.

[0118] According to various embodiments, a predetermined gap Gap_1 can be formed between the bendable central portion 163 of the display 160 and the hinge structures 200a and 200b. An adhesive layer can be disposed on a peripheral area (e.g., the upper portion 161 or the lower portion 162) of the display 160, outside the central portion 163.

[0119] FIG. 8 A view of a first designated angle state of a first hinge structure according to various embodiments is illustrated.

[0120] Referring to FIG. 1A and FIG. 8 , the first hinge structure 200a can include a first designated angle state. As described above, the first hinge structure 200a can include a first rotation bracket 211, a second rotation bracket 212, a fixed bracket 213, a first arm 221, a second arm 222, a gear structure 230, a cam portion 241, a first elastic body 242a, a second elastic body 242b, a first rotation member 231, a second rotation member 232, and a support bracket 243. The first rotation bracket 211 can be connected with the first arm 221 by a first fixing portion 251. The rotation bracket 212 can be connected with the second arm 222 by a second fixing portion 252.

[0121] The first housing (e.g., the first housing 110 of FIG. 1A ) to which the first rotation bracket 211 is fixed or the second housing (e.g., the second housing 120 of FIG. 1A ) to which the second rotation bracket 212 is fixed can be rotated by a predetermined angle in the direction of the vertical axis 803 from one point on the horizontal axis 801 of the illustrated drawing by external pressure. For example, the first rotation bracket 211 connected to the first housing 110 can be rotated in the direction of the vertical axis 803 from one point on the horizontal axis 801 (e.g., the -y axis or the y axis of FIG. 4 ) by a predetermined angle by external pressure. For example, the second rotation bracket 212 connected to the second housing 120 can be rotated in the direction of the vertical axis 803 from one point on the horizontal axis 801 (e.g., the -x axis or the x axis of FIG. 4direction of the vertical axis 803 from the right side of the illustrated drawing). When the first rotating bracket 211 rotates the first angle under the action of the external pressure, the corresponding pressure can be transmitted to the first arm 221 through the first fixing part 251. Accordingly, the first arm 221 can rotate the first angle on the horizontal axis 801 in the direction of the vertical axis 803 about the first rotating member 231. In this operation, the force depending on the rotational motion can be transmitted to the first rotating cam 221_4 and the first insertion part 221_3. The first rotating member 231, one side of which is inserted into the first insertion part 221_3, can rotate with the rotation of the first insertion part 221_3, and the first shaft gear 231_2 of the first rotating member 231 can rotate according to the rotation of the first rotating member 231. The first idler gear 233 and the second idler gear 234, which are engaged with each other, can rotate according to the rotation of the first shaft gear 231_2. Accordingly, the second shaft gear 232_2 can rotate, and the second rotating member 232 can rotate accordingly. The second insertion part 222_3 can rotate according to the rotation of the second rotating member 232, the second arm 222 can rotate according to the rotation of the second insertion part 222_3, and the second rotating bracket 212 connected to the second arm 222 through the second fixing part 252 can rotate according to the rotation of the second arm 222.

[0122] As described above, the first hinge structure 200a can have a structure in which the first rotating bracket 211 and the second rotating bracket 212 simultaneously rotate under the action of an external pressure (or force). Accordingly, even if an external pressure is applied to the second housing 120 to which the second rotating bracket 212 is connected, or an external pressure is simultaneously applied to the first housing 110 and the second housing 120, the first rotating bracket 211 and the second rotating bracket 212 can simultaneously rotate. When the first housing 110 and the second housing 120 of the electronic device 100 of the present disclosure simultaneously rotate, the twisting of the first housing 110 and the second housing 120 can be suppressed, and precise hinge motion can be performed.

[0123] According to various embodiments, when the first arm 221 and the second arm 222 rotate the first designated angle, the ridge of the first rotating cam 221_4 and the ridge of the second rotating cam 222_4 can maintain contact with the vicinity of the top of the ridge of the first fixed cam 241_1a and the vicinity of the top of the ridge of the second fixed cam 241_1a.

[0124] According to an embodiment, the first virtual shaft 11 of the first rotation support 211 and the second virtual shaft 12 of the second rotation support 212 can be disposed between the first rotation member 231 of the first arm 221 and the second rotation member 232 of the second arm 222, and thus, the amount of rotation of the first rotation support 211 can be different from the amount of rotation of the first arm 221. Accordingly, the upper surface of the first support body 211_1 of the first rotation support 211 can further protrude upward beyond the upper surface of the first base body 221_1 of the first arm 221 with respect to the horizontal axis 801. When the first rotation support 211 and the first arm 221 are connected by the first fixing part 251, the first fixing part 251 can slide along the first sliding hole 211_2 of the first rotation support 211 by a predetermined distance while the first rotation support 211 rotates. Similarly, the upper surface of the second support body 212_1 can rotate to further protrude beyond the upper surface of the second base body 222_1 with respect to the horizontal axis 801. Further, since the second rotation support 212 and the second arm 222 are connected by the second fixing part, the second fixing part 252 can slide along the second sliding hole 212_2 of the second rotation support 212 by a predetermined distance while the second rotation support 212 rotates.

[0125] FIG. 9 A view showing a second designated angle state of the first hinge structure according to various embodiments is illustrated.

[0126] Referring to FIG. 1A and FIG. 9 , the first hinge structure 200a can include a second designated angle state. The first hinge structure 200a can include, for example, a first rotation support 211, a second rotation support 212, a fixing support 213, a first arm 221, a second arm 222, a gear structure 230, a cam part 241, a first elastic body 242a, a second elastic body 242b, a first rotation member 231, a second rotation member 232, and a support support 243. The first rotation support 211 can be connected with the first arm 221 by a first fixing part 251, and the second rotation support 212 can be connected with the second arm 222 by a second fixing part 252.

[0127] The first housing (for example, FIG. 1A of the first housing 110) or the second housing (for example, FIG. 1AThe second housing 120) can be rotated by an external pressure (or force) by a second angle (e.g., 60 degrees) in the direction of the vertical axis 803 from a point on the horizontal axis 801 of the illustrated drawing. For example, when an external pressure or force is transmitted to the first housing 110 or the second housing 120, the first rotating bracket 211 or the second rotating bracket 212 can be rotated by a second angle (e.g., 60 degrees) in the direction of the vertical axis 803 from a point on the horizontal axis 801 (e.g., from the right side to the direction of the vertical axis 803 with respect to the illustrated drawing) around the first virtual axis 11 or the second virtual axis 12. In the process of performing the above operation, the applied force can be transmitted to each other through the first arm 221 or the second arm 222, and the first rotating member 231, the second rotating member 232, the gear structure 230, the first rotating bracket 211, the second rotating bracket 212, the first arm 221, and the second arm 222 can be simultaneously rotated.

[0128] When the first rotating bracket 211 and the second rotating bracket 212 are rotated by the second angle, the first fixing part 251 and the second fixing part 252 can slide in the first sliding hole 211_2 and the second sliding hole 212_2 closer to the fixing bracket 213 than when the first rotating bracket 211 and the second rotating bracket 212 are rotated by the first angle. In the process of the above operation, the first track 211_3 of the first rotating bracket 211 can be rotated outward from the center of the fixing bracket 213 to the right with respect to the illustrated drawing, and the second track 212_3 of the second rotating bracket 212 can be rotated outward from the center of the fixing bracket 213 to the left with respect to the illustrated drawing. Since the rotation axes of the first rotating bracket 211 and the first arm 221 are different from each other, and the rotation axes of the second rotating bracket 212 and the second arm 222 are different from each other, the distance between the upper surface of the first bracket body 211_1 and the upper surface of the second bracket body 212_1 can be formed to be shorter than the distance between the upper surface of the first base 221_1 and the upper surface of the second base 222_1 in the case of being close to the fixing bracket 213.

[0129] FIG. 10 A view showing a second state of some structures of an electronic device according to various embodiments is illustrated.

[0130] Referring to FIG. 1A and FIG. 10The electronic device 100 can include the first hinge structure 200a and the display 160. The second state of the first hinge structure 200a can include a folded state. The first hinge structure 200a can include, for example, a fixed bracket 213, a first rotating bracket 211, a second rotating bracket 212, a first arm 221, a second arm 222, a first fixing portion 251, a second fixing portion 252, a first rotating member 231, a second rotating member 232, a gear structure 230 including a first rotating member 231 and a second rotating member 232, a first elastic body 242a, a second elastic body 242b, and a support bracket 243.

[0131] In the above structure, the first rotating bracket 211 and the second rotating bracket 212 can be disposed to face each other. Since the edges of the first housing 110 and the second housing 120 abut each other with respect to the illustrated drawing, the first rotating bracket 211 can rotate about the first virtual axis 11 and can be inclined to the left at a specified angle with respect to the vertical axis 803 in the illustrated drawing. Also, the second rotating bracket 212 can rotate about the second virtual axis 12 and can be inclined to the right at a specified angle with respect to the vertical axis 803. The first virtual axis 11 can be a central axis of rotation of the first track 211_3, and the second virtual axis 12 can be a central axis of rotation of the second track 212_3. The first arm 221 can rotate about the first rotating member 231 and can be disposed side by side with the first rotating bracket 211, and the second arm 222 can rotate about the second rotating member 232 and can be disposed side by side with the second rotating member 232. Accordingly, the central portion of the display 160 can be bent in a "U" shape, and the remaining area can be maintained in a flat state.

[0132] When the first rotating bracket 211 and the first arm 221 are disposed vertically (or inclined to the left at a predetermined angle with respect to the vertical axis 803), the upper surface of the first bracket body 211_1 of the first rotating bracket 211 and the upper surface of the first base 221_1 of the first arm 221 can be disposed side by side without a height difference therebetween. Since the lengths of the first rotating bracket 211 and the first arm 221 are different, the first fixing portion 251 can be located at the lower edge of the first sliding hole 211_2 of the first rotating bracket 211. When the electronic device 100 is in the flat state, the first fixing portion 251 can be located at the upper edge of the first sliding hole 211_2 of the first rotating bracket 211. Similarly, when the electronic device 100 is in the folded state, the second fixing portion 252 can be located at the lower edge of the second sliding hole 212_2.

[0133] When the electronic device 100 changes from the first state to the second state (e.g., a folded state), the first rotating bracket 211 can rotate outward from the central portion of the fixed bracket 213 to the right with reference to the illustrated drawing, and when the electronic device 100 changes from the second state to the first state (e.g., flat), the first rotating bracket 211 can rotate in a direction from the right side of the fixed bracket 213 to the central portion thereof with reference to the illustrated drawing. According to an embodiment, the second rotating bracket 212 can rotate outward from the central portion of the fixed bracket 213 to the left with reference to the illustrated drawing at the same time as the electronic device 100 changes from the first state to the second state (e.g., a folded state), and when the electronic device 100 changes from the second state to the first state (e.g., a flat state), the second rotating bracket 212 can rotate in a direction from the left side of the fixed bracket 213 to the central portion thereof with reference to the illustrated drawing. When the electronic device 100 remains in the folded state, the ridges and valleys of the cam portion 241 can be engaged with the valleys and ridges of the rotating cam provided on the first and second arms 221 and 222. Accordingly, the first and second elastic bodies 242a and 242b can return from a state of being compressed in the first and second designated angle states to an initial state (e.g., a released state).

[0161] FIG. 12 A view showing one example of a folded state of an electronic device according to an embodiment is illustrated.

[0162] Referring to FIG. 12When the first and second housings 110 and 120 of the electronic device 100 are in the folded state, as illustrated, a gap Gap_2 can be formed in a region where the hinge housing 150 is coupled with the first or second housing 110 or 120. The gap Gap_2 can be caused by the height of the side wall of the hinge housing 150, and the gap Gap_2 of the hinge housing 150 can be observed from the outside when the hinge structure 200 is in the folded state. The gap Gap_2 can be formed to prevent the hinge housing 150 from obstructing the hinge movement of the hinge structure 200 when the hinge structure 200 is folded or unfolded. Thus, the gap Gap_2 can be observed between the hinge housing 150 and the hinge structure 200 when the electronic device 100 is in the folded state. The observation of the gap Gap_2 can be a factor that reduces the appearance integrity of the electronic device 100. For example, a portion of the hinge structure 200 disposed inside can be observed from the outside through the gap Gap_2.

[0163] FIG. 13 A view illustrating another example of a folded state of an electronic device according to an embodiment is shown.

[0164] Referring to FIG. 13 When the first and second housings 110 and 120 are in the folded state, the ends of the side portions 158a and 158b of the hinge housing 150 can be formed to be higher than the ends of the first and second housings 110 and 120 in the direction of the vertical axis 803 by a designated height. Thus, when the electronic device 100 is in the folded state, only the hinge housing 150 can be observed from the outside, and no separate gap can be observed at the boundary between the hinge housing 150 and the housings 110 and 120. Thus, since each end of the side portions 158a and 158b of the hinge housing 150 is formed at a position higher than each end of the first and second housings 110 and 120 in the direction of the vertical axis 803 by the designated height, the first and second accommodation grooves 221_9 and 222_9 can be disposed on predetermined regions of the first and second arms 221 and 222 to prevent collision with the first and second arms 221 and 222. The first and second accommodation grooves 221_9 and 222_9 can include, for example, the first accommodation groove 221_9 disposed at one end of the first arm 221 and the second accommodation groove 222_9 disposed at one end of the second arm 222. When the electronic device 100 is in the flat state, the first side portion 158a of the hinge housing 150 can be accommodated in the first accommodation groove 221_9, and the second side portion 158b of the hinge housing 150 can be accommodated in the second accommodation groove 222_9.

[0165] According to various embodiments, since the ends of the side portions 158a and 158b of the hinge housing 150 are formed at positions higher than the ends of the first housing 110 and the second housing 120 in the direction of the vertical axis 803 by a designated height, the third accommodation groove 211_9 and the fourth accommodation groove 212_9 can be disposed on the second rotation support 211 and the second rotation support 212. The third accommodation groove 211_9 can be formed on a central portion of the first rotation support 211 (e.g., between the first track 211_3 and the first housing connection hole 211_4 shown). FIG. 4 Similarly, the fourth accommodation groove 212_9 can be formed on a central portion of the second rotation support 212 (e.g., between the second track 212_3 and the second housing connection hole 212_4). When the electronic device 100 is in the flat state, the first side portion 158a can be accommodated in the third accommodation groove 211_9, and the second side portion 158b can be accommodated in the fourth accommodation groove 212_9. FIG. 4

[0166] According to the use of the above-described structure, the heights of the side portions 158a and 158b of the hinge housing 150 in the direction of the vertical axis 803 can be greater than the heights 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 can be located inside the first housing 110 and can be disposed at a position higher than a position of the lower end of the first housing 110, and at least a portion of the first side portion 158a can overlap with one end of the first housing 110 when viewed in the direction of the horizontal axis 801. Similarly, when the electronic device 100 is in the folded state, the second side portion 158b can be located inside the second housing 120 and can be disposed at a position higher than a position of the lower end of the second housing 120, and at least a portion of the second side portion 158b can overlap with one end of the second housing 120 when viewed in the direction of the horizontal axis 801.
