At least a portion of the first housing 110 is adhered to the upper portion 161 of the display 160. Alternatively, at least a portion of an edge of the front surface of the first housing 110 is adhered to an edge of the upper portion 161 of the display 160. Alternatively, one side of the upper portion of the front surface of the first housing 110 is adhered to one side of the upper portion 161 of the display 160. In this regard, a first adhesive layer 167a is disposed at least partially between the first housing 110 and the upper portion 161 of the display 160. At least a portion of the inside of the first housing 110 is hollow, or is connected to the first cover 119 and is hollow, and electronic elements necessary for driving the display 160 (e.g., elements such as a printed circuit board, at least one processor mounted on the printed circuit board, at least one memory, a battery, etc.) are arranged therein.
[0029] According to various embodiments, the edge ends of the first housing 110 (e.g., the edges of the remaining three edges excluding the edge facing the second housing 120) protrude a specified height from the bottom surface of the center of the housing to surround at least one edge of the display 160. Alternatively, at least a portion of the edge ends of the first housing 110 has a sidewall at least a portion of which faces the edge of the display 160. The sidewall formed on at least a portion of the edge of the first housing 110 is formed to have a specified height from the remaining three edges excluding the edge facing the second housing 120. The edge portion of the first housing 110 facing the second housing 120 includes a recessed portion, at least a portion of which has a certain curvature, so that at least a portion of the hinge housing 150 can be disposed therein. For example, the first housing 110 includes a first step portion 111 on which a portion of the hinge housing 150 having the first hinge structure 200a attached thereto is placed at the edge portion facing the second housing 120, and a second step portion 112 on which a portion of the hinge housing 150 having the second hinge structure 200b attached thereto is placed.
[0030] According to various embodiments, the second housing 120 is disposed next to the first housing 110 or has at least one surface facing one surface of the first housing 110 (e.g., the surface on which the display 160 is disposed). The second housing 120 is made of the same material as the first housing 110. The second housing 120 is disposed symmetrically to the first housing 110 in the left-right or top-bottom direction, and is disposed on its front surface to support at least a portion of a region of the display 160 other than the region disposed on the first housing 110 (e.g., the other side of the lower portion 162 and center portion 163 of the display 160). At least a portion of the second housing 120 is bonded to the lower portion 162 of the display 160. Alternatively, an edge of the front surface of the second housing 120 is bonded to an edge of the lower portion 162 of the display 160.

For example, as shown in FIG. 1a, when the first housing 110 and the second housing 120 are arranged side by side, the hinge housing 150 is covered 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 are arranged to face each other, the hinge housing 150 is arranged so that at least a portion of the hinge housing 150 is exposed to the outside at an edge of one side of the first housing 110 and the second housing 120 (e.g., an edge where the first housing 110 and the second housing 120 face each other in the unfolded state).
[0035] According to various embodiments, the display 160 is provided with at least a portion thereof being flexible. According to one embodiment, the display 160 includes an upper portion 161 or a first region disposed on the first housing 110, a lower portion 162 or a second region disposed on the second housing 120, and a central portion 163 or a center region where the first housing 110 and the second housing 120 are adjacent to each other. According to various embodiments, the entire display 160 is flexible. Alternatively, at least a portion of the central portion 163 of the display 160 is provided with flexibility. The central portion 163 of the display 160 is disposed so that the first housing 110 and the second housing 120 are not adhered to each other. For example, the central portion 163 of the display 160 is disposed so as to be spaced a certain distance from the front surfaces of the first housing 110 and the second housing 120. The upper portion 161 of the display 160 is adhered to at least a portion of the first housing 110, and the lower portion 162 of the display 160 is adhered to at least a portion of the second housing 120. In this regard, a first adhesive layer 167a is disposed in at least a portion of the area between the display 160 and the first housing 110, and a second adhesive layer 167b is disposed in at least a portion of the area between the display 160 and the second housing 120. The first adhesive layer 167a and the second adhesive layer 167b are disposed only on the edges of the first housing 110 and the second housing 120.
[0036] FIG. 2 is a diagram illustrating an example of a hinge structure and a hinge housing of an electronic device according to various embodiments.

In the illustrated drawing, a first hinge structure 200a and a second hinge structure 200b are arranged on a hinge housing 150. However, the present invention is not limited thereto, and three or more hinge structures may be arranged on the hinge housing 150 as needed.
[0038] The first hinge structure 200a is disposed on one side (e.g., the left side in the illustrated drawing) of the hinge housing 150. The first hinge structure 200a is coupled to the left side of the first housing 110 and the left side of the second housing 120, and rotates within a specified range based on the horizontal axis of the hinge housing 150. The first hinge structure 200a is disposed symmetrically to the second hinge structure 200b based on the center of the hinge housing 150.
[0039] The second hinge structure 200b is disposed on the other side of the hinge housing 150 (for example, on the right side in the illustrated drawing). The second hinge structure 200b is coupled to the right side of the first housing 110 and the right side of the second housing 120, and rotates within a specified range based on the horizontal axis of the hinge housing 150. The second hinge structure 200b is disposed symmetrically to the first hinge structure 200a based on the center of the hinge housing 150. The second hinge structure 200b has the same structure and configuration as the first hinge structure 200a, but is disposed in a different position.
[0040] The hinge housing 150 may have a semi-cylindrical shape with an open interior or a boat-like shape formed by cutting a pipe with both ends closed in the lengthwise direction. According to various embodiments, the hinge housing 150 includes a flat bottom 151_3 and a first rib 151_1 and a second rib 151_2 formed with a constant curvature on both sides of the bottom 151_3. The first rib 151_1 and the second rib 151_2 are symmetrically disposed on both sides of the bottom 151_3. The width of the hinge housing 150 gradually decreases from the center toward the left and right ends based on the illustrated drawing. At least one partition 158 is formed inside the hinge housing 150 to separate the interior spaces of the hinge housing 150. At least a portion of the first hinge structure 200a and the second hinge structure 200b are placed in the separated spaces, respectively. Shielding walls 151a and 151b are formed on the left and right sides of the hinge housing 150, protruding from the periphery to prevent the inside of the hinge housing 150 from being observed from the outside. The hinge housing 150 is made of the same material as the first hinge structure 200a or the second hinge structure 200b.
[0041] FIG. 3 is a view showing one side of a hinge structure applied to an electronic device according to various embodiments.
[0042] 3, the hinge structure (200a, 200b) is either the first hinge structure 200a or the second hinge structure 200b described above. The hinge structure (200a, 200b) includes a bracket structure 210, an arm detent structure 220, a gear structure 230, and a detent support structure 240.
[0043] The bracket structure 210 has a center portion fixed to the hinge housing 150, and both wings (for example, rotating brackets) are coupled to the first housing 110 and the second housing 120, and are also coupled to the arm detent structure 220.
[0044] The arm detent structure 220 is connected at one side to the bracket structure 210 by fixing portions (251, 252), and the installation angle is changed by sliding along the side of the bracket structure 210 through hinge operation. The arm detent structure 220 includes a cam structure that engages with a cam portion 241 disposed on the detent support structure 240 to provide a detent feeling when the first housing 110 and the second housing 120 hinge.
[0045] The gear structure 230 is disposed between the bracket structure 210 and the arm detent structure 220. The gear structure 230 transmits force so that when the first housing 110 rotates, the second housing 120 rotates together. In this regard, the gear structure 230 includes a plurality of shaft gears and idle gears.
[0046] The detent support structure 240 is fixed to the inside of the hinge housing 150 and applies a specified pressure to the arm detent structure 220. In this regard, the detent support structure 240 includes at least one elastic body, and the elastic force of the elastic body is used to push the cam portion 241 toward the arm detent structure 220, whereby the cam portion 241 engages with the rotating cam structure of the arm detent structure 220, thereby assisting the cam action.
[0047] As described above, the hinge structure (200a, 200b) according to one embodiment includes a bracket structure 210 that is coupled to the hinge housing 150 and the housings (110, 120) and assists in folding or unfolding the display 160 placed on top, an arm detent structure 220 that is connected to the bracket structure 210 and provides a detent feeling, a gear structure 230 that assists in simultaneous movement of the first housing 110 and the second housing 120, and a detent support structure 240 that supports the arm detent structure 220 and to which the axis of the gear structure 230 is fixed. Based on this, the hinge structures (200a, 200b) rotate about a virtual axis formed above the surface of the bracket structure 210 to fold or unfold the display 160, provide a detent feeling based on the cam structure, and support simultaneous hinge movement of the housings (110, 120) based on the gear structure 230 to suppress distortion of the housings (110, 120). In addition, the hinge structures (200a, 200b) support not only the unfolded or folded state of the housings (110, 120) but also a fixed state at a specified angle, for example, 30 degrees or 60 degrees (for example, the intersection angle between the front face of the first housing 110 and the front face of the second housing 120).
[0048] FIG. 4 is an exploded perspective view of the hinge structure of FIG.
[0049] In the following description, the first hinge structure of the hinge structures (200a, 200b) will be taken as an example. The structure and configuration of the first hinge structure 200a described in FIG. 4 are the same as those of the second hinge structure 200b described above.
[0050] Referring to FIG. 4, the first hinge structure 200a includes a fixed bracket 213, a first rotating bracket 211, a second rotating bracket 212, a first fixed portion 251, a second fixed portion 252, a first arm portion 221, a second arm portion 222, a first rotating member 231 that rotates around a first rotation axis different from the first imaginary axis 11, a second rotating member 232 that rotates around a second rotation axis different from the second imaginary axis 12, a stopper 236, a cam portion 241, a first elastic body 242a, a second elastic body 242b, a support bracket 243, a first idle gear 233, a second idle gear 234, a support plate 235, and a plurality of fixing clips (291_1, 291_2, 292_1, 292_2, 249_1, 249_2). The first hinge structure 200a is at least partially made of a metal material to provide a certain level of rigidity, or may be made of reinforced plastic, resin, or other suitable material, as required.
[0051] At least a portion of the shape of the lower surface (e.g., the surface in the -z-axis direction) of the fixed bracket 213 includes a curved surface. For example, the lower surface of the fixed bracket 213 is formed to correspond to the inner shape of the hinge housing 150. The upper surface (e.g., the surface in the z-axis direction) of the fixed bracket 213 is formed to have a flat shape, and rail grooves (213a, 213b) are formed therein to couple the rotating brackets (211, 212). According to one embodiment, the fixed bracket 213 includes a first rail groove 213a in which at least a portion of the cross section is arc-shaped from the upper surface (e.g., the surface in the z-axis direction) to the lower surface (e.g., the surface in the -z-axis direction), and into which the first rail 211_3 of the first rotating bracket 211 is inserted from the first direction (e.g., the y-axis direction) to the second direction (e.g., the -y-axis direction). According to one embodiment, the fixed bracket 213 has at least a portion of its cross section arc-shaped from its upper surface (e.g., the surface in the z-axis direction) to its lower surface (e.g., the surface in the -z-axis direction), and includes a second rail groove 213b into which the second rail 212_3 of the second rotating bracket 212 is inserted from the second direction (e.g., the -y-axis direction) to the first direction (e.g., the y-axis direction). The first rail groove 213a is offset in the y-axis direction compared to the second rail groove 213b, and the second rail groove 213b is offset in the -y-axis direction compared to the first rail groove 213a. The first rail groove 213a rotates about a first virtual axis 11, and the second rail groove 213b rotates about a second virtual axis 12. The first imaginary axis 11 and the second imaginary axis 12 are formed above (air) an upper surface (e.g., a surface in the z-axis direction) of the fixing bracket 213, and the first imaginary axis 11 and the second imaginary axis 12 are formed to be spaced apart by a specified interval. According to one embodiment, the fixing bracket 213 is formed on a side portion disposed in a third direction (e.g., the x-axis direction) and includes a first mounting groove 213_2a in which one end of the first rotating member 231 (e.g., at least a part of the first mounting portion 231_3) is mounted, and a second mounting groove 213_2b in which one end of the second rotating member 232 (e.g., at least a part of the second mounting portion 232_3) is mounted.
[0052] According to various embodiments, the fixing bracket 213 includes a first fixing hole 213_1a and a second fixing hole 213_1b used to fix the fixing bracket 213 to the hinge housing 150. The electronic device 100 fixes the fixing bracket 213 to the hinge housing 150 using a connecting member (e.g., a screw, etc.). According to one embodiment, the first fixing hole 213_1a and the second fixing hole 213_1b are arranged diagonally symmetrically on an upper surface (e.g., a surface in the z-axis direction) of the fixing bracket 213 to fix the fixing bracket 213 to the hinge housing 150 more firmly and stably.
[0053] The first rotating bracket 211 includes a first bracket body 211_1, a first sliding hole 211_2 formed at one side end (e.g., the end in the x-axis direction) of the first bracket body 211_1, a first rail 211_3 formed at the other side end (e.g., the end in the -y-axis direction) of the first bracket body 211_1, and a first housing connecting hole 211_4 used for connecting to the first housing 110.
[0054] The first bracket body 211_1 is generally L-shaped. An upper surface (e.g., a surface disposed in the z-axis direction) of the first bracket body 211_1 is flat. With reference to the illustrated drawing, a first sliding hole 211_2 is disposed in a lower direction (e.g., a -z-axis direction) at a right end (e.g., an end in the x-axis direction) of the first bracket body 211_1, and a first rail 211_3 is disposed in a lower surface (e.g., a surface disposed in the -z-axis direction) at one end (e.g., an end in the -y-axis direction) of the first bracket body 211_1.
[0055] The first sliding hole 211_2 is disposed at the other end (e.g., end in the x-axis direction) of the first bracket body 211_1 and at a lower part of the first bracket body 211_1. The first sliding hole 211_2 is formed so that its length in a first direction (e.g., y-axis direction) is longer than its length in a third direction (e.g., x-axis direction). This allows the first fixing portion 251 inserted into the first sliding hole 211_2 to slide in either the first direction (e.g., y-axis direction) or the second direction (e.g., −y-axis direction) within the first sliding hole 211_2. The first sliding hole 211_2 is disposed so as to face a surface of the first arm portion 221 in the fourth direction (e.g., a surface disposed in the −x-axis direction). At least a partial region of the first sliding hole 211_2 is aligned with the first connecting portion 221_2 of the first arm portion 221. As a result, at least a portion of the first fixed portion 251 is disposed inside the first slide hole 211_2 and the first connecting portion 221_2.
[0056] The first rail 211_3 is disposed at an end of the first bracket body 211_1 in the second direction (for example, an end in the -y-axis direction) and at a lower portion of the first bracket body 211_1. The first rail 211_3 is formed in an arc shape with a certain angle. The first rail 211_3 is inserted into a first rail groove 213a disposed in the fixed bracket 213 and rotates along the first rail groove 213a within a specified angle range. According to one embodiment, the rotation range of the first rail 211_3 is, for example, a range of -10 degrees to 100 degrees (or a range of 0 degrees to 90 degrees). The first rail 211_3 rotates between the y-axis and the z-axis with respect to a first virtual axis 11 formed by the first rail groove 213a.
[0057] The first housing coupling hole 211_4 is formed on one side (e.g., one side end facing the y-axis direction) of the first bracket body 211_1 and penetrates a first direction surface (e.g., a surface facing the y-axis direction) and a second direction surface (e.g., a surface facing the -y-axis direction). In the illustrated drawings, two first housing coupling holes 211_4 are formed on the first bracket body 211_1, but the present invention is not limited to this number. A coupling member is at least partially fastened to the first housing coupling holes 211_4 and coupled to a boss or the like provided on the first housing 110 to fix the first rotating bracket 211 to the first housing 110.
[0058] The second rotating bracket 212 includes a second bracket body 212_1, a second sliding hole 212_2 formed at one side end (e.g., the end in the x-axis direction) of the second bracket body 212_1, a second rail 212_3 formed at the other side end (e.g., the end in the y-axis direction) of the second bracket body 212_1, and a second housing connecting hole 212_4 used for connecting to the second housing 120.
[0059] The second bracket body 212_1 is provided to have substantially the same shape as the first bracket body 211_1, so that the upper surface (for example, the surface disposed in the z-axis direction) of the second bracket body 212_1 is formed flat.
[0060] The second sliding hole 212_2 is disposed at the right end (for example, the end in the x-axis direction) of the second bracket body 212_1 and at the bottom of the second bracket body 212_1. The second sliding hole 212_2 is disposed symmetrically with the first sliding hole 211_2 with respect to the fixed bracket 213. The second sliding hole 212_2 has the same shape as the first sliding hole 211_2.
[0061] The second rail 212_3 is disposed at an end of the second bracket body 212_1 in the first direction (for example, an end in the y-axis direction) and at a lower portion of the second bracket body 212_1. The second rail 212_3 is provided in substantially the same shape as the first rail 211_3 and is inserted into the second rail groove 213b. The second rail 212_3 rotates within a specified angle range, for example, 80 degrees to 190 degrees (or 90 degrees to 180 degrees), with the second virtual axis 12 as the reference. For example, the second rail 212_3 rotates within a range between the -y-axis and the z-axis.
[0062] The second housing connecting hole 212_4 is formed on one side (e.g., one side end facing the -y-axis direction) of the second bracket body 212_1 and is formed to penetrate the first direction surface (e.g., the y-axis direction surface) and the second direction surface (e.g., the -y-axis direction surface).
[0063] The first fixing portion 251 is pin-shaped and has a certain length in one direction. The first fixing portion 251 is formed to be at least longer than the sum of the hole length of the first sliding hole 211_2 and the hole length of the first connecting portion 221_2 of the first arm portion 221. After the first fixing portion 251 is inserted into the first sliding hole 211_2 and the first connecting portion 221_2, each of the two ends of the fixing portion 251 is fixed. The diameter of the first fixing portion 251 is formed to be smaller than the diameter of the first connecting portion 221_2. The first fixing portion 251 is positioned within the first sliding hole 211_2 and slides in the y-axis or -y-axis direction.
[0064] The second fixing portion 252 has substantially the same shape as the first fixing portion 251. The second fixing portion 252 is disposed symmetrically to the first fixing portion 251 with respect to the fixing bracket 213, and at least a portion of the second fixing portion 252 is inserted and fixed into the second sliding hole 212_2 and the second connecting portion 222_2. One side of the second fixing portion 252 slides in the y-axis or -y-axis direction within the second sliding hole 212_2.
[0065] The first arm portion 221 is fastened to the first rotating bracket 211 by a first fixing portion 251, and rotates within a specified angle range in cooperation with the first rotating bracket 211 when a hinge operation is performed. According to an embodiment, the first arm portion 221 includes a first basic body 221_1, a first connecting portion 221_2, a first inserting portion 221_3, and a first rotating cam 221_4.
[0066] The first basic body 221_1 has a flat upper surface (e.g., a surface facing the z-axis). A first connecting part 221_2 is disposed on a lower surface (e.g., a surface facing the -z-axis direction) of an upper end (e.g., an end of the y-axis) of the first basic body 221_1. The first connecting part 221_2 includes a hole that opens in a fourth direction (e.g., the -x-axis direction). A first fixing part 251 is placed and fixed on the first connecting part 221_2.
[0067] A first insertion part 221_3 is disposed on a lower surface (e.g., a surface in the -z-axis direction) of a lower end (e.g., an end in the -y-axis direction) of the first basic body 221_1. The first insertion part 221_3 includes a hole that opens in the fourth direction (e.g., the -x-axis direction) and has at least a portion of an angular cross section. At least a portion of the first rotating member 231 is placed on the first insertion part 221_3. A first rotating cam 221_4 is disposed on one side (e.g., an end in the x-axis direction) of the first insertion part 221_3.
[0068] The first rotating cam 221_4 includes at least one peak and a valley disposed on a side of the first inserting portion 221_3 where the first rotating member 231 is inserted and protrudes. According to an embodiment, the ends of the peak and the valley include flat regions having a predetermined length. As a result, while the first rotating cam 221_4 rotates in engagement with the first fixed cam 241_1a of the cam portion 241, a section of a predetermined width where the peak end of the first rotating cam 221_4 contacts the peak end of the first fixed cam 241_1a is formed. When the section of a predetermined width where the peak end of the first rotating cam 221_4 contacts the peak end of the first fixed cam 241_1a is formed, the first housing 110 and the second housing 120 are more firmly maintained at a predetermined angle within the corresponding section, and a variety of angular ranges of the mounting state can be provided.
[0069] The second arm portion 222 has substantially the same configuration as the first arm portion 221. For example, the second arm portion 222 includes a second basic body 222_1, a second connecting portion 222_2, a second insertion portion 222_3, and a second rotating cam 222_4. The second basic body 222_1 is disposed symmetrically with the first basic body 221_1, and the second connecting portion 222_2 is fastened to one side of the second fixed portion 252. The second rotating member 232 is inserted into the second insertion portion 222_3, and the second rotating cam 222_4 is disposed to engage with the second fixed cam 241_1b of the cam portion 241.
[0070] The first rotating member 231 has one end placed in a first mounting groove 213_2a formed in the fixing bracket 213 and is gear-coupled to the first idle gear 233, and is disposed to penetrate the stopper 236, the first insertion portion 221_3, the first rotating cam 221_4, the first fixed cam 241_1a of the cam portion 241, and the first elastic body 242a, and is fixed to the support bracket 243. The first rotating member 231 includes a first shaft body 231_1, a first shaft gear 231_2, and a first mounting portion 231_3.
[0071] The first shaft body 231_1 has a length that passes through the stopper 236, the first insertion portion 221_3, the first rotating cam 221_4, the first fixed 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 is coupled to the first rotating cam 221_4 and has an angular cross section along the y-axis to rotate the first rotating cam 221_4 when rotated by external pressure. For example, the first shaft body 231_1 includes a plurality of flat surfaces along the length (e.g., the x-axis direction or the -x-axis direction). Correspondingly, the inner wall of the first insertion portion 221_3, in which the first rotating cam 221_4 is disposed, has a shape that corresponds to the cross section of the first shaft body 231_1. The first shaft gear 231_2 is disposed so as to be biased toward the fourth direction (for example, the −x-axis direction) of the first shaft body 231_1. The first shaft gear 231_2 is disposed so as to be gear-coupled to the first idle gear 233.
[0072] The first mounting portion 231_3 is formed to further protrude from a surface of the first shaft gear 231_2 in the fourth direction (for example, a surface in the −x-axis direction). At least a portion of the first mounting portion 231_3 passes through a guide hole formed in the support plate 235 and is mounted in a first mounting groove 213_2a formed in the fixed bracket 213. The first fixing portion 251 fixes the first rotating bracket 211 and the first arm portion 221, so that the first mounting portion 231_3 is firmly fixed to the first mounting groove 213_2a, thereby preventing separation or distortion of the first shaft body 231_1.
[0073] The second rotating member 232 has one end placed in a second mounting groove 213_2b formed in the fixed bracket 213 and is gear-coupled to the second idle gear 234, and is disposed to penetrate the stopper 236, the second insertion portion 222_3, the second rotating cam 222_4, the second fixed cam 241_1b of the cam portion 241, and the second elastic body 242b, so that the other end of the second rotating member 232 is fixed to the support bracket 243. The second rotating member 232 includes a second shaft body 232_1, a second shaft gear 232_2, and a second mounting portion 232_3.
[0074] The second shaft body 232_1 has a length that passes through the stopper 236, the second insertion portion 222_3, the second rotating 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 has substantially the same shape and size as the first shaft body 231_1. The second shaft body 232_1 is disposed at a position spaced a predetermined distance from the first shaft body 231_1. The second shaft gear 232_2 has the same shape and size as the first shaft gear 231_2 and is disposed on the second shaft body 232_1. The position of the second shaft gear 232_2 is symmetrical to the position of the first shaft gear 231_2. At least a portion of the second mounting portion 232_3 has the same shape and size as the first mounting portion 231_3 and is mounted in the second mounting groove 213_2b. During this process, at least a portion of the second mounting portion 232_3 passes through the guide hole of the support plate 235 and is mounted in the second mounting groove 213_2b. During the process in which the second fixing portion 252 fixes the second rotating bracket 212 and the second arm portion 222, the second mounting portion 232_3 is firmly mounted in the second mounting groove 213_2b.
[0075] The stopper 236 supports pressure to prevent the first arm portion 221 and the second arm portion 222 from rotating beyond a specified angle or to prevent pressure from being applied that would cause the first arm portion 221 and the second arm portion 222 to rotate outside a specified angle range. The stopper 236 includes a stopper 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.
[0076] According to various embodiments, the stopper body 236_1 is formed to protrude in a third direction (e.g., the x-axis direction) beyond the surfaces of the first shaft insertion hole 236a and the second shaft insertion hole 236b. The stopper body 236_1 is disposed to limit the rotation range of one side of the first arm portion 221 (e.g., the fourth direction surface of the first insertion portion (e.g., the -x-axis direction surface)) while the first arm portion 221 rotates, and to limit the rotation range of one side of the second arm portion 222 (e.g., the fourth direction surface of the second insertion portion (e.g., the -x-axis direction surface)) while the second arm portion 222 rotates.
[0077] One side (e.g., the surface in the x-axis direction) of the first shaft insertion hole 236a and the second shaft insertion hole 236b is arranged to face the fourth direction surface (e.g., the surface in the −x-axis direction) of the first insertion portion 221_3 and the fourth direction surface (e.g., the surface in the −x-axis direction) of the second insertion portion 222_3 of the first arm portion 221. The third direction surface (e.g., the surface in the x-axis direction) of the stopper body 236_1 is arranged to face the fourth direction surface (e.g., the surface in the −x-axis direction) of the cam body 241_1 of the cam portion 241.
[0078] The cam portion 241 includes 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 has a certain length, and the first fixed cam 241_1a and the second fixed cam 241_1b are arranged on both side ends. The fourth direction surface (e.g., the surface in the −x-axis direction) of the cam body 241_1 is arranged to face the third direction surface (e.g., the surface in the x-axis direction) of the stopper body 236_1. The first fixed cam 241_1a has peaks and valleys arranged in the fourth direction (e.g., the −x-axis direction), and a first cam hole 241_2a is formed in the center so that the first rotating member 231 passes through. The first fixed cam 241_1a is arranged to mesh with the first rotating cam 221_4. One side of the first elastic body 242a contacts the surface of the first fixed cam 241_1a in the third direction (for example, the surface in the x-axis direction). The second fixed cam 241_1b is arranged in the same direction as the first fixed cam 241_1a and is arranged to be spaced apart from the first fixed cam 241_1a by the length of the y-axis of the cam body 241_1. The second fixed cam 241_1b is arranged to mesh with the second rotating cam 222_4, and the second elastic body 242b contacts the surface of the second fixed cam 241_1b in the third direction (for example, the surface in the x-axis direction). A second cam hole 241_2b is formed in the center of the second fixed cam 241_1b so that the second rotating member 232 passes through.
[0079] According to various embodiments, while the first arm portion 221 and the second arm portion 222 rotate within a certain angle range, the cam portion 241 retreats in a third direction (e.g., the x-axis direction) due to the first rotating cam 221_4 and the second rotating cam 222_4, and then moves in a fourth direction (e.g., the -x-axis direction) due to the elasticity of the first elastic body 242a and the second elastic body 242b when the cam peaks and valleys engage with each other, and returns to its original position.
[0080] The first elastic body 242a has a spring shape with an open center. The first shaft body 231_1 of the first rotating member 231, which penetrates the first fixed cam 241_1a, is placed in the center of the first elastic body 242a. The first elastic body 242a and the second elastic body 242b are disposed between the cam portion 241 and the support bracket 243, and act to press the cam portion 241 in the fourth direction (e.g., the -x-axis direction) when the support bracket 243 is fixed. The second elastic body 242b is disposed a specified distance away from the first elastic body 242a and disposed so as to contact the surface of the second fixed cam 241_1b in the third direction (e.g., the surface in the x-axis direction).
[0081] The support bracket 243 includes a support portion 243_1, a first support bracket hole 243_2a, and a second support bracket hole 243_2b. The support portion 243_1 includes a through-hole 243_1a that penetrates vertically (for example, in the -z-axis direction at a point on the z-axis). The through-hole 243_1a is used to fix the support bracket 243 to the hinge housing 150. The first support bracket hole 243_2a protrudes from one side of the support portion 243_1 to support one side of the first elastic body 242a. One end of the first rotating member 231 is inserted into the first support bracket hole 243_2a. The second support bracket hole 243_2b is located at a predetermined distance from the first support bracket hole 243_2a and protrudes from one side of the support portion 243_1 to support one side of the second elastic body 242b. Also, one end of the second rotating member 232 is inserted into the second support bracket hole 243_2b.
[0082] The first idle gear 233 is disposed between the first shaft gear 231_2 and the second shaft gear 232_2, and has one side gear-coupled to the first shaft gear 231_2 and the other side gear-coupled to the second idle gear 234. The first idle gear 233 includes a protrusion inserted into a guide hole formed in the support plate 235 and a protrusion fixed to a surface of the stopper 236 in the fourth direction (for example, a surface in the −x-axis direction).
[0083] The second idle gear 234 is disposed between the first shaft gear 231_2 and the second shaft gear 232_2, and one side of the second idle gear 234 is gear-coupled to the first idle gear 233, and the other side of the second idle gear 234 is gear-coupled to the second shaft gear 232_2. The second idle gear 234 is formed to have substantially the same shape and size as the first idle gear 233. Accordingly, the second idle gear 234 includes a protrusion inserted into a guide hole formed in the support plate 235, and a protrusion fixed to a fourth direction surface (e.g., a surface in the −x-axis direction) of the stopper 236. In this regard, a groove or a hole is formed in the fourth direction surface (e.g., a surface in the −x-axis direction) of the stopper 236 to receive the protrusion of the first idle gear 233 and the protrusion of the second idle gear 234.
[0084] The support plate 235 is disposed between the fixed bracket 213 and the rotating members (231, 232) to prevent the rotating members (231, 232) and the idle gears (233, 234) from coming off.

[0090] FIG. 6 is a diagram illustrating a stopper connection structure of a hinge structure according to various embodiments.
[0091] Referring to FIG. 6, the stopper connection structure of the hinge structure according to an embodiment includes a first arm portion 221, a second arm portion 222, a first rotating member 231, a second rotating member 232, and a stopper 236.
[0092] As described above with reference to FIG. 4, the first rotating member 231 includes a first shaft body 231_1, a first shaft gear 231_2, and a first mounting portion 231_3, which are arranged in series. The first shaft body 231_1 has a specified length so that the stopper 236, the first insertion portion 221_3, the first rotating cam 221_4, the cam portion 241, the first elastic body 242a, etc. can be inserted therein, and at least a portion of the exterior thereof has an angular shape (e.g., a polygonal cross section or a shape including multiple faces) in relation to the rotation of the first arm portion 221. A first fixing groove 231_1a is arranged at an end of the first shaft body 231_1 (e.g., the end opposite the first mounting portion 231_3) into which a fixing clip (e.g., 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 is arranged on one side of the first mounting portion 231_3, into which a fixing clip (e.g., the third fixing clip 292_1) is inserted to be inserted and placed in the first mounting groove 213_2a and to prevent it from coming off the support plate 235.
[0093] The second rotating member 232, like the first rotating member 231, has a second shaft body 232_1, a second shaft gear 232_2, and a second mounting portion 232_3 arranged so that they are continuous. The second shaft body 232_1 is provided similarly to or identical to the first shaft body 231_1. An end portion (e.g., an end portion opposite the second mounting portion 232_3) of the second shaft body 232_1 is provided with a third fixing groove 232_1a into which a fixing clip (e.g., the sixth fixing clip 249_2) is inserted to fix the second shaft body 232_1 to the support bracket 243. An end portion (e.g., an end portion opposite the second mounting portion 232_3) of the second shaft body 232_1 is provided with a fourth fixing groove 232_3a into which a fixing clip (e.g., the fourth fixing clip 292_2) is inserted to insert into the second mounting groove 213_2b and to prevent the second mounting portion 232_3 from coming off the support plate 235.
[0094] The stopper 236 includes a stopper body 236_1, a first shaft insertion hole 236a, and a second shaft insertion hole 236b. The first shaft insertion hole 236a is disposed between the first arm portion 221 inserted into the first shaft body 231_1 and the first shaft gear 231_2. The second shaft insertion hole 236b is disposed between the second arm portion 222 inserted into the second shaft body 232_1 and the second shaft gear 232_2.

According to one embodiment, the stopper body 236_1 includes a third locking jaw 236_2c arranged to support the other side 221_1b of the first arm portion 221 when the electronic device 100 is in the folded state, and a fourth locking jaw 236_2d arranged to support the other side 222_1b of the second arm portion 222. Based on the structure of the stopper 236 described above, the first arm portion 221 and the second arm portion 222 are supported to prevent further rotation in the rotational direction when in the unfolded or folded state.
[0095] FIG. 7 is a diagram illustrating a first state of a configuration of an electronic device according to various embodiments.
[0096] 1a and 7, a portion of an electronic device includes a first hinge structure 200a and a display 160, where the first hinge structure 200a and the display 160 are in a first state (eg, an unfolded state).
[0097] As described above, the first hinge structure 200a includes the first rotating bracket 211, the second rotating bracket 212, the fixed bracket 213, the first arm portion 221, the second arm portion 222, the gear structure 230 including the shaft gears and idle gears of the first rotating member 231 and the second rotating member 232, the cam portion 241, the first elastic body 242a, the second elastic body 242b, the first rotating member 231, the second rotating member 232, and the support bracket 243. The first rotating bracket 211 is connected to the first arm portion 221 by a first fixed portion 251. The second rotating bracket 212 is connected to the second arm portion 222 by a second fixed portion 252.
[0098] While the first rotating bracket 211 and the second rotating bracket 212 maintain their unfolded states, the display 160 maintains its unfolded state. The first arm unit 221 rotates within a specified angle range based on the first rotating member 231. The second arm unit 222 rotates within a specified angle range based on the second rotating member 232. The first rotating bracket 211 rotates within a similar or identical angle range to the first arm unit 221 based on the first imaginary axis 11. The second rotating bracket 212 rotates within a similar or identical angle range to the second arm unit 222 based on the second imaginary axis 12. The first imaginary axis 11 is formed higher in the direction of the display 160 than the first rotating member 231. The second imaginary axis 12 is formed higher in the direction of the display 160 than the second rotating member 232. The distance between the first virtual axis 11 and the second virtual axis 12 is shorter than the distance between the first rotating member 231 and the second rotating member 232. According to various embodiments, the first virtual axis 11 and the second virtual axis 12 are formed side by side on a horizontal axis. According to one embodiment, the first virtual axis 11 and the second virtual axis 12 are formed on the same layer as the display 160 or above the display 160 (for example, in the air above the display 160).
[0099] While the first rotating bracket 211 and the second rotating bracket 212 maintain their unfolded states, the first bracket body 211_1 of the first rotating bracket 211 and the second bracket body 212_1 of the second rotating bracket 212 are arranged side by side. According to one embodiment, the top surfaces of the first bracket body 211_1 and the second bracket body 212_1 are arranged to face the same upward direction based on the illustrated drawing. According to one embodiment, while the first rotating bracket 211 and the second rotating bracket 212 maintain their unfolded states, the first arm portion 221 and the second arm portion 222 are also arranged side by side, and therefore the first basic body 221_1 of the first arm portion 221 and the second basic body 222_1 of the second arm portion 222 are arranged to face the same direction (e.g., upward based on the illustrated drawing). As a result, the first bracket body 211_1, the second bracket body 212_1, the first basic body 221_1, and the second basic body 222_1 are all arranged side by side with the horizontal axis as the reference and are all arranged facing the same upward direction with respect to the illustrated drawing. The first bracket body 211_1, the second bracket body 212_1, the first basic body 221_1, and the second basic body 222_1 support the rear surface of the display 160 without any difference in height.
[0100] According to various embodiments, a certain gap Gap_1 is formed between the hinge structures (200a, 200b) and the center of the display 160 where the display 160 bends. An adhesive layer is disposed on the peripheral area (e.g., the upper portion 161 or the lower portion 162) of the display 160 other than the center portion 163.
[0101] FIG. 8 is a diagram illustrating a first designated angle state of a first hinge structure according to various embodiments.
[0102] 1a and 8, the first hinge structure 200a includes a first specified angle state. As described above, the first hinge structure 200a includes a first rotating bracket 211, a second rotating bracket 212, a fixed bracket 213, a first arm portion 221, a second arm portion 222, a gear structure 230, a cam portion 241, a first elastic body 242a, a second elastic body 242b, a first rotating member 231, a second rotating member 232, and a support bracket 243. The first rotating bracket 211 is connected to the first arm portion 221 by a first fixed portion 251. The second rotating bracket 212 is connected to the second arm portion 222 by a second fixed portion 252.
[0103] When external pressure is applied, the first housing (e.g., first housing 110 in FIG. 1A) to which the first rotating bracket 211 is fixed or the second housing (e.g., second housing 120 in FIG. 1A) to which the second rotating bracket 212 is fixed rotates by a certain angle from a point on horizontal axis 801 to a vertical axis 803, based on the illustrated drawing. For example, the first rotating bracket 211 connected to the first housing 110 rotates by a first angle (e.g., 30 degrees) from a point on horizontal axis 801 (e.g., the -y-axis or y-axis in FIG. 4) to a direction of vertical axis 803 (e.g., the z-axis in FIG. 4) based on the first virtual axis 11 (e.g., from the right side to the direction of vertical axis 803, based on the illustrated drawing). When the first rotating bracket 211 rotates by the first angle due to external pressure, the corresponding pressure is transmitted to the first arm portion 221 via the first fixing portion 251. As a result, the first arm portion 221 rotates by a first angle from above the horizontal axis 801 in the direction of the vertical axis 803 with respect to the first rotating member 231. This operation transmits force due to the rotation to the first rotating cam 221_4 and the first insertion portion 221_3. The first rotating member 231, one side of which is inserted into the first insertion portion 221_3, rotates due to the rotation of the first insertion portion 221_3, and as a result, the first shaft gear 231_2 of the first rotating member 231 rotates as the first shaft gear 231_2 rotates. The rotation of the first shaft gear 231_2 rotates the first idle gear 233 and the second idle gear 234, which are gear-coupled with each other, and as a result, the rotation of the second shaft gear 232_2 rotates the second rotating member 232. Rotation of the second rotating member 232 causes the second insertion portion 222_3 to rotate, rotation of the second insertion portion 222_3 causes the second arm portion 222 to rotate, and rotation of the second arm portion 222 causes the second rotating bracket 212 connected by the second fixing portion 252 to rotate.
[0104] As described above, the first hinge structure 200a has a structure in which the first rotating bracket 211 and the second rotating bracket 212 rotate simultaneously in response to pressure (or force) applied from the outside. As a result, even if external pressure occurs in the second housing 120 to which the second rotating bracket 212 is connected, or if external pressure occurs simultaneously in the first housing 110 and the second housing 120, the first rotating bracket 211 and the second rotating bracket 212 rotate simultaneously. In the electronic device 100 of the present invention, the simultaneous rotation reduces distortion of the first housing 110 and the second housing 120, allowing for accurate hinge operation.
[0105] According to various embodiments, as the first arm portion 221 and the second arm portion 222 rotate by a specified first angle, the peaks of the first rotating cam 221_4 and the second rotating cam 222_4 maintain contact near the peaks of the peaks of the first fixed cam 241_1a and the second fixed cam 241_1b, respectively.
[0106] According to one embodiment, the imaginary axes (11, 12) of the first rotating bracket 211 and the second rotating bracket 212 are disposed between the first rotating member 231 and the second rotating member 232 of the first arm portion 221 and the second arm portion 222, so that the rotation amount of the first rotating bracket 211 differs from the rotation amount of the first arm portion 221. As a result, the upper surface of the first bracket body 211_1 of the first rotating bracket 211 protrudes further from the upper surface of the first basic body 221_1 of the first arm portion 221 relative to the horizontal axis 801. The first rotating bracket and the first arm portion 221 are connected by the first fixing portion 251, so that the first fixing portion 251 slides a certain distance along the first sliding hole 211_2 of the first rotating bracket 211 while the first rotating bracket 211 rotates. Similarly, the upper surface of the second bracket body 212_1 rotates so as to protrude further than the second basic body 222_1 based on the horizontal axis 801. In addition, since the second rotating bracket and the second arm portion 222 are connected by the second fixing portion 252, the second fixing portion 252 slides a certain distance along the second sliding hole 212_2 of the second rotating bracket 212 while the second rotating bracket 212 rotates.
[0107] FIG. 9 is a diagram illustrating a second designated angle state of a first hinge structure according to various embodiments.
[0108] 1a and 9, the first hinge structure 200a includes a second specified angle state. The first hinge structure 200a includes, for example, a first rotating bracket 211, a second rotating bracket 212, a fixed bracket 213, a first arm portion 221, a second arm portion 222, a gear structure 230, a cam portion 241, a first elastic body 242a, a second elastic body 242b, a first rotating member 231, a second rotating member 232, and a support bracket 243. The first rotating bracket 211 is connected to the first arm portion 221 by a first fixed portion 251, and the second rotating bracket 212 is connected to the second arm portion 222 by a second fixed portion 252.
[0109] When an external pressure (or force) is applied, the first housing (e.g., first housing 110 in FIG. 1a) or the second housing (e.g., second housing 120 in FIG. 1a) rotates by a second angle (e.g., 60 degrees) from a point on horizontal axis 801 in the direction of vertical axis 803 with reference to 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 rotates by a second angle (e.g., 60 degrees) from a point on horizontal axis 801 in the direction of vertical axis 803 (e.g., from the right side with reference to the illustrated drawing in the direction of vertical axis 803) with reference to the first imaginary axis 11 or the second imaginary axis 12. The force applied during the above-mentioned operation is transmitted between the first arm portion 221 or the second arm portion 222, the first rotating member 231 and the second rotating member 232, and the gear structure 230, causing the first rotating bracket 211, the second rotating bracket 212, the first arm portion 221, and the second arm portion 222 to rotate simultaneously.
[0110] As the first rotating bracket 211 and the second rotating bracket 212 rotate at the second angle, the first fixed part 251 and the second fixed part 252 slide within the first sliding hole 211_2 and the second sliding hole 212_2, sliding closer to the fixed bracket 213 than in the state rotated at the first angle. During the above-mentioned operation process, the first rail 211_3 of the first rotating bracket 211 rotates outward to the right from the center of the fixed bracket 213, and the second rail 212_3 of the second rotating bracket 212 rotates outward to the left from the center of the fixed bracket 213, based on the illustrated drawing. Since the rotation axis of the first rotating bracket 211 and the rotation axis of the first arm portion 221 are different from each other, and the rotation axis of the second rotating bracket 212 and the rotation axis of the second arm portion 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 is formed to be shorter in the direction toward the fixed bracket 213 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.
[0111] FIG. 10 is a diagram illustrating a second state of a partial structure of an electronic device according to various embodiments.
[0112] 1a and 10, electronic device 100 includes first hinge structure 200a and display 160. The second state of first hinge structure 200a is the folded state. First hinge structure 200a includes, for example, fixed bracket 213, first rotating bracket 211, second rotating bracket 212, first arm portion 221, second arm portion 222, first fixed portion 251, second fixed portion 252, first rotating member 231, second rotating member 232, gear structure 230 including shaft gears of first rotating member 231 and second rotating member 232, first elastic body 242a, second elastic body 242b, and support bracket 243.
[0113] In the above-described structure, the first rotating bracket 211 and the second rotating bracket 212 are disposed to face each other. With reference to the illustrated drawings, the edge portions of the first housing 110 and the second housing 120 are disposed adjacent to each other, so that the first rotating bracket 211 rotates about the first imaginary axis 11 and is tilted to the left by a specified angle about the vertical axis 803. Alternatively, the second rotating bracket 212 rotates about the second imaginary axis 12 and is tilted to the right by a specified angle about the vertical axis 803. For example, the first imaginary axis 11 serves as a rotation center axis of the first rail 211_3, and the second imaginary axis 12 serves as a rotation center axis of the second rail 212_3. The first arm unit 221 rotates based on the first rotating member 231 and is placed next to the first rotating bracket 211, and the second arm unit 222 rotates based on the second rotating member 232 and is placed next to the second rotating bracket 212. As a result, the center of the display 160 is bent in a "U" shape, while the remaining area remains flat.
[0114] When the first swivel bracket 211 and the first arm unit 221 are installed vertically (or tilted leftward by a specified angle based on the vertical axis 803), the upper surface of the first bracket body 211_1 of the first swivel bracket 211 and the upper surface of the first basic body 221_1 of the first arm unit 221 are arranged side by side without any difference in height. Due to the difference in length between the first swivel bracket 211 and the first arm unit 221, the first fixing portion 251 is located at the lower end of the first sliding hole 211_2 of the first swivel bracket 211. When the electronic device 100 is in the unfolded state, the first fixing portion 251 is located at the upper end of the first sliding hole 211_2 of the first swivel bracket 211. Similarly, when the electronic device 100 is in the folded state, the second fixing portion 252 is located at the lower end of the second sliding hole 212_2.
[0115] The first rotating bracket 211 rotates from the center of the fixing bracket 213 to the outward right side with reference to the drawing while the electronic device 100 is changing from a first state to a second state (e.g., a folded state), and rotates from the outward right side of the fixing bracket 213 toward the center with reference to the drawing while the electronic device 100 is changing from the second state to the first state (e.g., an unfolded state). According to one embodiment, the second rotating bracket 212 rotates from the center of the fixing bracket 213 to the outward left side with reference to the drawing while the electronic device 100 is changing from the first state to the second state (e.g., a folded state), and rotates from the outward left side of the fixing bracket 213 toward the center with reference to the drawing while the electronic device 100 is changing from the second state to the first state (e.g., an unfolded state). While the electronic device 100 maintains the folded state, the peaks and valleys of the cam portion 241 are disposed to engage with the peaks and valleys of the rotating cams disposed on the first arm portion 221 and the second arm portion 222. As a result, the first elastic body 242a and the second elastic body 242b are restored to their initial states (e.g., released states) from the compressed states in the first specified angle state and the second specified angle state.
[0116] FIG. 11 illustrates additional structures of the first hinge structure according to various embodiments.
[0117] Referring to FIG. 11, the first hinge structure 200a (or the second hinge structure) includes a fixed bracket 213, a first rotating bracket 211, a second rotating bracket 212, a first arm portion 221, a second arm portion 222, a first fixed portion 251, a second fixed portion 252, a first rotating member 231, a second rotating member 232, a gear structure 230 including shaft gears and idle gears of the first rotating member 231 and the second rotating member 232, a cam portion 241, a first elastic body 242a, a second elastic body 242b, and a support bracket 243, and additionally or alternatively, at least one washer ring and ring plate 237 are further added.
[0118] The at least one washer ring includes, for example, a first washer ring 238_1a and a second washer ring 238_1b inserted onto the first rotating member 231.

[0143] FIG. 12 is a diagram illustrating an example of a folded state of an electronic device according to an embodiment.
[0144] 12 , when the first housing 110 and the second housing 120 of the electronic device 100 are in a folded state, a gap Gap_2 is formed in a region where the hinge housing 150 is coupled to the first housing 110 or the second housing 120, as shown in the figure. The gap Gap_2 is caused by the height of the sidewall of the hinge housing 150, and when the hinge structure 200 is in a folded state, the gap Gap_2 of the hinge housing 150 is visible from the outside. This gap Gap_2 is formed because the hinge housing 150 must not interfere with the hinge operation of the hinge structure 200 while the hinge structure 200 is being folded or unfolded. Therefore, when the electronic device 100 is in a folded state, the gap Gap_2 is visible between the hinge housing 150 and the hinge structure 200. The presence of this gap Gap_2 can detract from the appearance of the electronic device. For example, a part of the hinge structure 200 disposed inside via the gap Gap_2 is observed from the outside.
[0145] FIG. 13 illustrates another example of a folded state of an electronic device according to an embodiment.
[0146] 13, when the first housing 110 and the second housing 120 are folded, the ends of the side portions (158a, 158b) of the hinge housing 150 are formed higher by a specified height in the direction of the vertical axis 803 than the ends of the first housing 110 and the second housing 120. As a result, when the electronic device 100 is viewed from the outside in the folded state, no gap is observed at the boundary region between the hinge housing 150 and the housings (110, 120), and only the hinge housing 150 is visible. In this regard, first and second receiving grooves (221_9, 222_9) are disposed in certain regions of the first and second rotating brackets 211, 212 to prevent collision between the first and second rotating brackets 211, 212 due to the side portions (158a, 158b) of the hinge housing 150 being formed higher by a specified height in the direction of the vertical axis. The first and second receiving grooves (221_9, 222_9) include, for example, a first receiving groove 221_9 disposed at an end of the first rotating bracket 211 and a second receiving groove 222_9 disposed at an end of the second rotating bracket 212. When the electronic device 100 is in an unfolded state, the first side portion 158a of the hinge housing 150 is received in the first receiving groove 221_9, and the second side portion 158b of the hinge housing 150 is received in the second receiving groove 222_9.
[0147] According to various embodiments, third and fourth receiving grooves 211_9 and 212_9 are also disposed in the first arm portion 221 and the second arm portion 222 in response to the height of the first side portion 158a and the second side portion 158b of the hinge housing 150 being increased by a predetermined height in the direction of the vertical axis 803. The third receiving groove 211_9 is formed in the center of the first arm portion 221 (e.g., between the first rail 211_3 and the first housing coupling hole 211_4 shown in FIG. 4). Similarly, the fourth receiving groove 212_9 is formed in the center of the second arm portion 222 (e.g., between the second rail 212_3 and the second housing coupling hole 212_4 shown in FIG. 4). When the electronic device 100 is in an unfolded state, the first side portion 158a is received in the third receiving groove 211_9, and the second side portion 158b is received in the fourth receiving groove 212_9.
[0148] By employing the above-described structure, the height of the sides (158a, 158b) of the hinge housing 150 in the direction of the vertical axis 803 is greater than the depth of the first housing 110 and the second housing 120 in the direction below the vertical axis (-803). For example, when the electronic device 100 is folded, the first side 158a is located inside the first housing 110 and is positioned higher than the lower end of the vertical axis of the first housing 110, and at least a portion of the first side 158a overlaps the end of the first housing 110 when viewed from the direction of the horizontal axis 801. Similarly, when the electronic device 100 is folded, the second side 158b is located inside the second housing 120 and is positioned higher than the lower end of the vertical axis of the second housing 120, and at least a portion of the second side 158b overlaps the end of the second housing 120 when viewed from the direction of the horizontal axis (e.g., 801).
[0149] FIG. 14 is a view showing another example of a hinge housing and a hinge structure according to various embodiments, and FIG. 15 is an exploded perspective view of the hinge structure shown in FIG.
[0150] 14 and 15, a third hinge structure 200c and a fourth hinge structure 200d are disposed in a hinge housing 150 according to an embodiment.

The third hinge structure 200c (or the fourth hinge structure 200d) is at least partially made of a metal material and is provided to have a certain degree of rigidity. Alternatively, the third hinge structure 200c (or the fourth hinge structure 200d) may be made of a material such as reinforced plastic or resin, as required.
[0155] The fixed bracket 1513 has at least a portion of a curved shape on its lower surface (e.g., the surface in the -z-axis direction). For example, the lower surface of the fixed bracket 1513 is formed to correspond to the inner shape of the hinge housing 150. The upper surface of the fixed bracket 1513 (e.g., the surface in the z-axis direction) is flat, and rail grooves 1513a and 1513b are formed thereon to allow the rotating brackets 1511 and 1512 to be coupled thereto. The positions and arrangement of the rail grooves 1513a and 1513b are the same as those of the rail grooves 213a and 213b described above in FIG. 4. As a result, the first rotating bracket 1511 and the second rotating bracket 1512 inserted into the rail grooves 1513a and 1513b rotate in the same manner as the first rotating bracket 211 and the second rotating bracket 212 described above in FIG. 4.
