[0055] According to one embodiment, as illustrated in FIG. 2A, the width (W2) of the second housing (220) in the transverse direction (e.g., in the x-axis and -x-axis directions) may be configured to be smaller than the width (W1) of the first housing (210) in the transverse direction (e.g., in the x-axis and -x-axis directions). The width (W1) of the first housing (210) in the transverse direction (e.g., in the x-axis and -x-axis directions) may be configured to be substantially the same as the width (W3) of the third housing (230) in the transverse direction (e.g., in the x-axis and -x-axis directions). According to various embodiments, the width (W3) of the third housing (230) in the transverse direction (e.g., in the x-axis and -x-axis directions) may be configured to be larger or smaller than the width (W1) of the first housing (210) in the transverse direction (e.g., in the x-axis and -x-axis directions).

[0056] According to one embodiment, the first housing (210) and the second housing (220) are disposed on opposite sides of the first folding axis (A1) on which the first hinge assembly (HA1) is disposed, and may have an asymmetrical shape with respect to the first folding axis (A1). According to various embodiments, the first housing (210) and the second housing (220) may also have a symmetrical shape with respect to the first folding axis (A1). The angle or distance between the first housing (210) and the second housing (220) may vary depending on whether the multi-foldable electronic device (200) is in an unfolded state, a folded state, or an intermediate state.

[0057] According to one embodiment, the first housing (210) and the third housing (230) are disposed on opposite sides of the second folding axis (A2) on which the second hinge assembly ((HA2)) is disposed, and may have a shape that is substantially symmetrical with respect to the second folding axis (A2). According to various embodiments, the first housing (210) and the third housing (230) may have an asymmetrical shape with respect to the second folding axis (A2). The angle or distance between the first housing (210) and the third housing (230) may vary depending on whether the multi-foldable electronic device (200) is in an unfolded state, a folded state, or an intermediate state.

[0058] According to various embodiments, as illustrated in FIG. 2A, the flexible display (240) may include a first region (240a) corresponding to at least a portion of the first housing (210), a second region (240b) extending from one side (e.g., the left side) of the first region (240a) and corresponding to at least a portion of the second housing (220), and a third region (240c) extending from the other side (e.g., the right side) of the first region (240a) and corresponding to at least a portion of the third housing (230). In one embodiment, the flexible display (240) may include a portion of a first region (240a) and a portion of a second region (240b), a fourth region (240d) that is flexible (e.g., a first folding region) corresponding to a first hinge assembly (HA1), and a fifth region (240e) that is flexible (e.g., a second folding region) corresponding to a second hinge assembly (HA2) and a portion of a first region (240a) and a portion of a third region (240c). In one embodiment, the region division of the flexible display (240) is merely an exemplary division by three housings (210, 220, 230) and two hinge assemblies (HA1, HA2), and the flexible display (240) may be displayed as a substantially seamless, single full screen. In one embodiment, the first region (240a) and the second region (240b) may have an overall symmetrical shape or a partially asymmetrical shape with respect to the fourth region (240d) and / or the first folding axis (A1). In one embodiment, the first region (240a) and the third region (240c) may have an overall symmetrical shape or a partially asymmetrical shape with respect to the fifth region (240e) and / or the second folding axis (A2). In one embodiment, the first folding width (BW1) of the fourth region (240d) may be smaller than the second folding width (BW2) of the fifth region (240e) in a direction perpendicular to the first folding axis (A1) (e.g., the x-axis direction). In some embodiments, the area of ​​the fourth region (240d) may be smaller than the area of ​​the fifth region (240e).This may be due to the fact that the first hinge assembly (HA1) connecting the first housing (210) and the second housing (220) and the second hinge assembly (HA2) connecting the first housing (210) and the third housing (230) are different from each other. For example, the size of at least one first hinge module (e.g., narrow hinge module) of the first hinge assembly (HA1) connecting the first housing (210) and the second housing (220) may be smaller than the size of at least one second hinge module (e.g., wide hinge module) of the second hinge assembly (HA2) connecting the first housing (210) and the third housing (230) and folding the flexible display (240) in a folded state. Through this configuration, the second hinge housing (267) can have a first width (L1) greater than the thickness of the first housing (210) (e.g., the first width (L1) of FIG. 4a), and the first hinge housing (266) can have a second width (L2) smaller than the first width (W1) (e.g., the second width (L2) of FIG. 4a).

[0059] According to one embodiment, the width of the second hinge assembly ((HA2)) may be configured to be wider than the width of the first hinge assembly (HA1). For example, the width (L2) of the second hinge assembly ((HA2)) may be configured to be wider than the width of the first hinge assembly (HA1), so that the second housing (220) may be folded first with respect to the first housing (210), and then the third housing (230) may be folded with respect to the first housing (210), such that the third housing (230) may be placed on top of the second housing (220). For example, the first hinge assembly (HA1) may be a first in-folding hinge, a slim hinge, or a small hinge having a narrower width than the second hinge assembly ((HA2)). For example, the second hinge assembly ((HA2)) may be a second in-folding hinge, wide hinge, or big hinge that is wider than the first hinge assembly (HA1). For example, the second hinge assembly ((HA2)) may have a larger radius of curvature than the first hinge assembly ((HA2)). The first hinge assembly (HA1) may have a smaller radius of curvature than the second hinge assembly ((HA2)). In one embodiment, the width of the second hinge assembly ((HA2)) is described as being wider than the width of the first hinge assembly (HA1), but the present invention is not limited thereto, and the width of the first hinge assembly (HA1) may be wider than the width of the second hinge assembly ((HA2)) depending on the type and / or operation of the multi-foldable electronic device (200).

[0060] According to one embodiment, as illustrated in FIG. 2A, when the multi-foldable electronic device (200) is in an unfolded state, the first housing (210) may include a first surface (211) that is connected to at least a portion of the first hinge assembly (HA1) and the second hinge assembly ((HA2)), and is arranged to face the front side (e.g., in the z-axis direction) of the multi-foldable electronic device (200), a second surface (212) that faces the opposite direction of the first surface (211), and / or a first side member (213) that surrounds at least a portion of a first space between the first surface (211) and the second surface (212). According to one embodiment, as illustrated in FIG. 2A, when the multi-foldable electronic device (200) is in an unfolded state, the second housing (220) may include a third surface (221) that is connected to at least a portion of the first hinge assembly (HA1) and is arranged to face the front (e.g., in the z-axis direction) of the multi-foldable electronic device (200), a fourth surface (222) that faces in an opposite direction to the third surface (221), and / or a second side member (223) that surrounds at least a portion of a second space between the third surface (221) and the fourth surface (222). According to one embodiment, as illustrated in FIG. 2A, when the multi-foldable electronic device (200) is in an unfolded state, the third housing (230) may include a fifth face (231) that is connected to at least a portion of the second hinge assembly ((HA2)) and arranged to face the front (e.g., in the z-axis direction) of the multi-foldable electronic device (200), a sixth face (232) that faces in an opposite direction to the fifth face (231), and / or a third side member (233) that surrounds at least a portion of a third space between the fifth face (231) and the sixth face (232).

[0061] According to various embodiments, as illustrated in FIGS. 2A and 2B , when the multi-foldable electronic device (200) is in an unfolded state, the first side (211), the third side (221), and the fifth side (231) may face substantially the same direction (e.g., the z-axis direction). When the multi-foldable electronic device (200) is in an unfolded state, the second side (212), the fourth side (222), and the sixth side (232) may face substantially the same direction (e.g., the -z-axis direction).

[0062] According to various embodiments, as illustrated in FIG. 3, when the first housing (210) and the second housing (220) of the multi-foldable electronic device (200) are in a folded state, the first side (211) and the third side (221) may be arranged to face each other.

[0064] According to various embodiments, when the multi-foldable electronic device (200) is in an unfolded state, the first housing (210), the second housing (220), and the third housing (230) form an angle of about 180°, and the first region (240a), the second region (240b), and the third region (240c) of the flexible display (240) form substantially the same plane and can be arranged to face substantially the same direction (e.g., the z-axis direction).

[0065] According to various embodiments, the first housing (210) and the second housing (220) can form an angle that can stop at a designated folding angle between a folded state and an unfolded state (e.g., a free stop function) using the first hinge assembly (HA1). In various embodiments, the second housing (220) can also be rotated to move toward the first side (211) (e.g., the front) of the first housing (210) while being pressed in the unfolding direction (e.g., the -z-axis direction) based on the designated inflection angle using the first hinge assembly (HA1).

In one embodiment, the multi-foldable electronic device (200) may include a second battery (B2) disposed in a second space (2201) of a second housing (220), and a second substrate (282) and a second sub-substrate (282a) connected through a second connection substrate (282b) with the second battery (B2) interposed therebetween. In one embodiment, the multi-foldable electronic device (200) may include a third battery (B3) disposed in a third space (2301) of a third housing (230), and a third substrate (283) and a third sub-substrate (283a) connected through a third connecting substrate (283b) with the third battery (B3) interposed therebetween.

[0093] According to various embodiments, at least one wiring member (284a, 284b) may include a first wiring member (284a) extending from a first space (2101) across a first hinge assembly (HA1) to a second space (2201) and a second wiring member (284b) extending from the first space (2101) across a second hinge assembly (HA2) to a third space (2301). In one embodiment, the first and second wiring members (284a, 284b) may include a flexible printed circuit board (FPCB) having a shape having an elastic restoring force capable of accommodating a folding motion of each of the housings (210, 220, 230). In one embodiment, the first substrate (281) and the second substrate (282) may be electrically connected via the first wiring member (284a). In one embodiment, the first substrate (281) and the third substrate (283) can be electrically connected through a second wiring member (284b).

[0094] According to various embodiments, the sizes of the first battery (B1), the second battery (B2), and the third battery (B3) may be determined by the number and / or arrangement structure of electronic components arranged in the first space (2101), the second space (2201), and the third space (2301). For example, the first battery (B1) may be set to the smallest size due to the arrangement structure of major components such as the first substrate (281), the first sub-substrate (281a), the second camera (273b), the antenna structure (AR1, AR2), or the connector port (276) including the processor (e.g., the processor (120) of FIG. 1) arranged in the first space (2101). In one embodiment, the second battery (B2) may be set to the largest size due to the arrangement structure of electronic components such as a speaker, a second substrate (282), or a second sub-substrate (282a). In one embodiment, the third battery (B3) may be set to a size larger than the first battery (B1) and smaller than the second battery (B2) due to the arrangement structure of electronic components such as a speaker, a third substrate (283), a third sub-substrate (283a), a key button (275), or a connector port (276). However, the present invention is not limited thereto, and the sizes of each of the first, second, and third batteries (B1, B2, B3) may be modified to various sizes by the arrangement design of the electronic components arranged in the first, second, and third spaces (2101, 2201, 2031).

[0095] According to various embodiments, the first housing (210), the second housing (220), and the third housing (230) of the electronic device (200) may include sensors (not shown) capable of detecting angles (e.g., folding angles and unfolding angles) between the housings (210, 220, 230). In one embodiment, a first sensor may be disposed in the first housing (210), a second sensor may be disposed in the second housing (220), and / or a third sensor may be disposed in the third housing (230). In one embodiment, the first sensor and / or the second sensor may detect the angle between the first housing (210) and the second housing (220). For example, when the first housing (210) and the second housing (220) are folded or unfolded through the first hinge assembly (HA1), the first sensor and / or the second sensor can detect the angle between the first housing (210) and the second housing (220). For example, the first sensor or the second sensor can include a 6-axis sensor, an acceleration sensor, a gyro sensor, and / or an angle sensor.

[0096] In one embodiment, the first sensor and / or the third sensor can detect an angle between the first housing (210) and the third housing (230). For example, when the first housing (210) and the third housing (230) are folded or unfolded through the second hinge assembly ((HA2)), the first sensor and / or the third sensor can detect the angle between the first housing (210) and the third housing (230). For example, the third sensor can include a 6-axis sensor, an acceleration sensor, a gyro sensor, and / or an angle sensor.

[0097] According to one embodiment, as illustrated in FIG. 5, the multi-foldable electronic device (200) may include at least one magnet (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14). In one embodiment, at least one magnet (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14) may include magnets (M1, M3, M4, M5, M6) arranged in a first space (2101) of a first housing (210), magnets (M2, M7, M8, M9, M10, M11) arranged in a second space (2201) of a second housing (220), and magnets (M12, M13, M14) arranged in a third space (2301) of a third housing (230).

[0098] In one embodiment, referring to FIG. 5, the magnets (M1, M3, M4, M5, M6) arranged in the first housing (210) may include a first magnet (M1) and at least one first additional magnet (M3, M4, M5, M6). The first magnet (M1) may be arranged to be aligned with a second magnet (M2) of a movable magnet module (400) arranged in the second housing (220) when the first housing (210) and the second housing (220) are in a folded state. In one embodiment, the first magnet (M1) may be arranged adjacent to an edge portion of a first side member (213) of the first housing (210) that is parallel to the first folding axis (A1), and the movable magnet module (400) may be arranged adjacent to an edge portion of a second side member (223) of the second housing (220) that is parallel to the first folding axis (A1). The first additional magnets (M3, M4, M5, M6) may include, but are not limited to, a third magnet (M3), a fourth magnet (M4), a fifth magnet (M5), and a sixth magnet (M6). In one embodiment, the first additional magnets (M3, M4, M5, M6) may have at least one magnet omitted or at least one magnet added.

[0099] In one embodiment, referring to FIG. 5, the magnets (M2, M7, M8, M9, M10, M11) arranged in the second housing (220) may include a second magnet (M2) and at least one second additional magnet (M7, M8, M9, M10, M11). In one embodiment, a moving magnet module (400) may be arranged in the second space (2201) of the second housing (220). In one embodiment, the moving magnet module (400) may include the second magnet (M2). In one embodiment, the processor (120) may move the second magnet (M2) of the moving magnet module (400) in a direction substantially parallel to the first folding axis (A1) by a specified distance (e.g., distance (L) in FIG. 9) so that a repulsive force is applied between the first magnet (M1) and the second magnet (M2) based on a signal detected from the first detection sensor or the second detection sensor, which will be described later, while the first housing (210) and the second housing (220) are folded with respect to the first folding axis (A1). In one embodiment, the second additional magnets (M7, M8, M9, M10, M11) may be positioned to align with the first additional magnets (M3, M4, M5, M6) positioned in the first housing (210) and / or the third additional magnets (M12, M13, M14) positioned in the third housing (230) when the first housing (210), the second housing (220), and the third housing (230) are fully folded relative to each other (e.g., a second state or fully folded state). The second additional magnets (M7, M8, M9, M10, M11) can exert an attractive force on the first additional magnets (M3, M4, M5, M6) and / or the third additional magnets (M12, M13, M14) when the first housing (210), the second housing (220), and the third housing (230) are completely folded relative to each other.In one embodiment, the second additional magnets (M7, M8, M9, M10, M11) may include, but are not limited to, a seventh magnet (M7), an eighth magnet (M8), a ninth magnet (M9), a tenth magnet (M10), and an eleventh magnet (M11). In one embodiment, the second additional magnets (M7, M8, M9, M10, M11) may have at least one magnet omitted or at least one magnet added. In one embodiment, referring to FIG. 5, the third additional magnets (M12, M13, M14) disposed in the third housing (230) may include, but are not limited to, a twelfth magnet (M12), a thirteenth magnet (M13), and a fourteenth magnet (M14). In one embodiment, the third additional magnets (M12, M13, M14) may have at least one magnet omitted or at least one magnet added.

[0100] In one embodiment, referring to FIG. 5, the fifth magnet (M5) and the sixth magnet (M6) of the first additional magnets (M3, M4, M5, M6) may be arranged in the first housing (210) to have the same magnetic direction as the thirteenth magnet (M13) and the fourteenth magnet (M13) of the third additional magnets (M12, M13, M14) when the multi-foldable electronic device (200) is in an unfolded state (e.g., a first state). In one embodiment, when the third housing (230) is folded relative to the first housing (210) relative to the second folding axis (A2) before the second housing (220) is folded relative to the first housing (210) relative to the first folding axis (A1), the fifth magnet (M5) and the sixth magnet (M6) of the first additional magnets (M3, M4, M5, M6) may face the thirteenth magnet (M13) and the fourteenth magnet (M13) of the third additional magnets (M12, M13, M14), respectively. In this case, a repulsive force may be applied between the fifth magnet (M5) and the thirteenth magnet (M13) and between the sixth magnet (M6) and the fourteenth magnet (M14). Therefore, reverse folding in which the third housing (230) is folded before the second housing (220) relative to the first housing (210) can be prevented.

[0101] In one embodiment, the first magnet (M1), the first additional magnets (M3, M4, M5, M6), the second additional magnets (M7, M8, M9, M10, M11), and the third additional magnets (M12, M13, M14) may be respectively disposed within recesses (not shown) formed in the first housing (210), the second housing (220), and the third housing (230). In one embodiment, the first magnet (M1), the first additional magnets (M3, M4, M5, M6), the second additional magnets (M7, M8, M9, M10, M11), and the third additional magnets (M12, M13, M14) may be disposed in the molding member (301) of FIG. 6a. In one embodiment, the first magnet (M1), the first additional magnet (M3, M4, M5, M6), the second additional magnet (M7, M8, M9, M10, M11) and the third additional magnet (M12, M13, M14) may be placed within recesses formed in the first housing (210), the second housing (220) and the third housing (230) while being accommodated in the molding member (301), respectively.

[0103] According to one embodiment, as illustrated in FIG. 6A, the multi-foldable electronic device (200) may include a molding member (301). The molding member (301) may include a non-conductive material (e.g., plastic). In one embodiment, at least one magnet (M1, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14) may be accommodated in the molding member (301) and disposed in the first housing (210), the second housing (220), or the third housing (230).

[0104] In one embodiment, any one of the first to fourteenth magnets (M1 to M14) may be replaced with an electromagnet that is set to have a polarity when powered. In one embodiment, the first to fourteenth magnets (M1 to M14) may be an array magnet and / or a Halbach Array Magnet (310). In one embodiment, the array magnet may be arranged so that multiple magnets have the same magnetic direction or may be arranged so that they have different magnetic directions (e.g., N pole, S pole). In one embodiment, the Halbach Array Magnet (310) may have at least one S pole and at least one N pole arranged alternately and / or staggered. For example, the Halbach Array Magnet (310) may have at least one S pole and at least one N pole arranged in various configurations and may provide various strengths of magnetic force. For example, the Halbach array magnet (310) can increase the strength of the magnetic force in one direction (e.g., direction ①) depending on the arrangement of at least one S pole and at least one N pole.

[0105] According to one embodiment, the multi-foldable electronic device (200) may include a shielding magnet (320). The shielding magnet (320) may be in the form of at least one magnet among the magnets (M1, M3 to M14) arranged in the multi-foldable electronic device (200) being wrapped with a shielding member (321). The shielding magnet (320) may amplify magnetic force in an area where magnetic force is required (e.g., direction ①) and shield magnetic force through the shielding member (321) in an area where magnetic force is unnecessary (e.g., direction ②). For example, the shielding member (321) may be arranged to correspond to an area where an electronic component sensitive to magnetic force (e.g., a printed circuit board) is arranged.

[0106] FIGS. 7A and 7B are drawings of an embodiment of the present disclosure in which a portion of a moving magnet module moves in a direction parallel to a folding axis.

[0107] According to one embodiment, a first magnet (M1) may be arranged in one of the first space (2101) of the first housing (210) and the second space (2201) of the second housing (220), and a moving magnet module (400) including a second magnet (M2) may be arranged in the other of the first space (2101) of the first housing (210) and the second space (2201) of the second housing (220).

[0108] According to one embodiment, as illustrated in FIG. 7A, when the first housing (210) and the second housing (220) are in a folded state (e.g., a second state or a third state), the first magnet (M1) and the second magnet (M2) of the moving magnet module (400) may be arranged in an attractive manner. Accordingly, the first housing (210) and the second housing (220) can maintain the folded state.

[0109] In one embodiment, referring to FIGS. 7A and 7B, the processor (120) may move the second magnet (M2) of the movable magnet module (400) in a direction substantially parallel to the first folding axis (A1) so that a repulsive force is applied between the first magnet (M1) and the second magnet (M2) based on a specific condition being satisfied when the first housing (210) and the second housing (220) are in a folded state (e.g., a third state) with respect to the first folding axis (A1). In one embodiment, the multi-foldable electronic device (200) may include a first detection sensor that detects a user's touch. In one embodiment, the first detection sensor may be a fingerprint recognition sensor, a pressure sensor (500) (e.g., a pressure sensor), and / or a touch sensor, as illustrated in FIGS. 10A and 10B, which will be described later. In one embodiment, the fingerprint recognition sensor may be arranged to detect a user's fingerprint through at least a portion of the key input device (275) or may be arranged in the foldable electronic device (200) separately from the key input device (275) to detect the user's fingerprint. In one embodiment, when the first detection sensor is a fingerprint recognition sensor, the processor (120) may generate a trigger signal based on whether the user's fingerprint information detected through the fingerprint recognition sensor matches the user's fingerprint information stored in the memory (130). For example, the memory (130) may include instructions that, when executed by the processor (120), generate a trigger signal based on whether the user's fingerprint information detected through the fingerprint recognition sensor matches the user's fingerprint information stored in the memory (130). In one embodiment, when the first detection sensor is a pressure-sensitive sensor (500), the processor (120) may generate a trigger signal based on whether the magnitude of the pressure detected through the pressure-sensitive sensor (500) is greater than or equal to a preset pressure. In one embodiment, when the first detection sensor is a touch sensor, the processor (120) can confirm a user's touch or swiping input input to the touch sensor and generate a trigger signal that generates current in the electrode (431).In one embodiment, the trigger signal may be an operation signal that controls the first substrate (430) to apply current to the wire (410) of the moving magnet module (400) via the electrode (431).

[0110] Hereinafter, specific configurations of the moving magnet module (400) for moving the second magnet (M2) of the moving magnet module (400) based on a trigger signal will be described. In addition, in the following description, for convenience of explanation, it is assumed that the first magnet (M1) is placed in the first housing (210) and the moving magnet module (400) is placed in the second housing (220), as illustrated in FIG. 5 described above. However, the following description can be equally applied to an embodiment in which the first magnet (M1) is placed in the second housing (220) and the moving magnet module (400) is placed in the first housing (210).

[0111] FIG. 8A is an assembly diagram of a fixed housing, a moving housing, and a magnet of a moving magnet module according to one embodiment of the present disclosure. FIG. 8B is a front perspective view of a moving magnet module according to one embodiment of the present disclosure. FIG. 8C is a rear perspective view of a moving magnet module according to one embodiment of the present disclosure. FIG. 9 is a diagram of an embodiment in which a moving housing of a moving magnet module moves relative to a fixed housing via a wire according to one embodiment of the present disclosure, wherein the moving housing is removed.

[0112] According to one embodiment, as illustrated in FIGS. 8A to 8C, the moving magnet module (400) may include a fixed housing (401) (e.g., a first housing, a first housing portion, a first housing structure, a first bracket, a first magnet housing), a moving housing (402) (e.g., a second housing, a second housing portion, a second housing structure, a second bracket, a second magnet housing), a wire (410), an elastic member (420), a first substrate (430), an electrode (431), and / or a second magnet (M2). At least one of the above-described components may be omitted or at least one component may be added.

[0113] In one embodiment, the fixed housing (401) may be fixed to the second housing (220). For example, the fixed housing (401) may be received in a recess (not shown) formed in the second housing (220) and fixed to the second housing (220), or may be disposed on one surface of the second housing (220) and fixed to the second housing (220) through a separate connecting member (e.g., a screw). In some embodiments, when the moving magnet module (400) is disposed in the first housing (210), the fixed housing (401) may be fixed to the first housing (210).

[0114] In one embodiment, the movable housing (402) can be slidably coupled to the fixed housing (401). In one embodiment, the second magnet (M2) can be disposed in the movable housing (402). In one embodiment, the second magnet (M2) can be inserted and accommodated within the interior of the movable housing (402). In one embodiment, the second magnet (M2) can be fixed to the movable housing (402) so that it can move together when the movable housing (402) slides relative to the fixed housing (401).

[0115] In one embodiment, the fixed housing (401) and the movable housing (402) may be formed of a material that includes carbon and is lightweight and durable, such as CFRP (Carbon Fiber Reinforced Plastic). In addition, the fixed housing (401) and the movable housing (402) may be formed of a metal material and / or a non-metal material. Here, the metal material may include an alloy such as aluminum, stainless steel (STS, SUS), iron, magnesium, or titanium, and the non-metal material may include a synthetic resin, ceramic, or engineering plastic.

[0116] According to one embodiment, as illustrated in FIG. 8B, the fixed part housing (401) may include a slit (4011) (e.g., a rail, a recess) in which a portion of the movable part housing (402) and a fixed member (F) are received. In one embodiment, the coupling portion (e.g., the first coupling portion (4022) and the second coupling portion (4023)) of the movable part housing (402) may be received in the slit (4011) of the fixed part housing (401). In one embodiment, the first coupling portion (4022) and the second coupling portion (4023) of the movable part housing (402) may be fastened to the fixed member (F) (e.g., a screw, a thread) while being received in the slit (4011) of the fixed part housing (401). In one embodiment, the movable housing (402) can be maintained in a coupled state with the fixed member (F) by the fixed member (F) being supported through one surface of the fixed member housing (401) while being fastened to the fixed member (F). In one embodiment, the fixed member (F) can move along the slit (4011) of the fixed member housing (401) in a direction parallel to the first folding axis (A1) with respect to the movable housing (402) with respect to the fixed member housing (401).

[0117] According to one embodiment, as illustrated in FIGS. 8A, 8B, 8C, and 9, the moving magnet module (400) may include a first substrate (430). In one embodiment, the first substrate (430) of the moving magnet module (430) may be electrically connected to a second substrate (282) disposed in the second housing (220). In one embodiment, the first substrate (430) of the moving magnet module (430) may be electrically connected to the second substrate (282) through a separate flexible printed circuit board (FPCB). In one embodiment, the first substrate (430) of the moving magnet module (430) may be directly connected to the second substrate (282) through a connector. In some embodiments, where the moving magnet module (400) is disposed in the first housing (210) and the first magnet (M1) is disposed in the second housing (220), the first substrate (430) of the moving magnet module (400) may be connected to the first substrate (281) disposed in the first housing (210) through a separate flexible substrate or may be directly connected.

[0118] According to one embodiment, as illustrated in FIGS. 8A, 8C, and 9, the movable housing (402) can be moved relative to the fixed housing (401) via a wire (410). In one embodiment, one end of the wire (410) can be connected to an electrode (431) disposed on a first substrate (430) disposed at an end of the fixed housing (401). The other end of the wire (410) can be fastened to a hooking structure (403) formed on the movable housing (402). For example, the wire (410) can be fastened to the hooking structure (403) by being hooked to or penetrating the hooking structure (403).

[0119] In one embodiment, the wire (410) may include a shape memory alloy (SMA). In one embodiment, the shape memory alloy may be an alloy that returns to its original shape at a specific temperature. For example, the shape memory alloy may include nickel-titanium, copper-based alloy materials (e.g., CuZnAl, CuAlNi). In one embodiment, the wire (410) may return to its original shape based on reaching a preset critical temperature or higher in a low temperature state. In one embodiment, the wire (410) may return to its original shape based on reaching a preset temperature or lower in a high temperature state.

[0120] According to one embodiment, the processor (120) can identify a user's touch detected by the first detection sensor when the first housing (210) and the second housing (220) are in a folded state (e.g., a third state, an intermediate state) based on the first folding axis (A1). The processor (120) can generate a trigger signal for controlling the first substrate (430) to generate a current in the electrode (431) of the first substrate (430) based on information or a signal acquired through the first detection sensor. The wire (410) can be shaped as the temperature increases based on the current generated from the electrode (431). For example, the wire (410) can be formed using a shape memory alloy material so as to be shaped back to its original shape when heated to a critical temperature. The wire (410) can be lengthened or shortened in a direction parallel to the first folding axis (A1) when heated to the critical temperature or higher. In this case, the wire (410) may increase or decrease in length compared to the reference state before the current is applied based on the current generated from the electrode (431). Therefore, as illustrated in FIG. 9, based on the change in length of the wire (410), the moving unit housing (402) may move in a first direction (e.g., direction ① (e.g., + Y direction) or direction ② (e.g., - Y direction) of FIG. 9) parallel to the first folding axis (A1) with respect to the fixed unit housing (401). The change in length of the wire (410) may be a preset change amount (L) so as to generate a repulsive force between the first magnet (M1) and the second magnet (M2). The second magnet (M2) may move in the first direction by a predetermined length (L) together with the moving unit housing (402) so that the same polarity as the first magnet (M1) may face each other. Accordingly, as a repulsive force is applied between the first magnet (M1) and the second magnet (M2), the second housing (220) can be unfolded with respect to the first housing (210) with respect to the first folding axis (A1).

[0121] Thereafter, as the current flowing to the electrode (431) is cut off through the control of the processor (120), the wire (410) may be cooled and deformed to the length of the reference state before the current is applied. In one embodiment, the processor (120) may control the first substrate (430) to cut off the current flowing to the electrode (431) after a certain period of time has elapsed from the time when the current is generated. In some embodiments, the processor (120) may cut off the current flowing to the electrode (431) based on the first housing (210) and the second housing (220) being spread out at a certain angle. The moving housing (402) may move in a second direction (e.g., direction ② or direction ① of FIG. 9) opposite to the first direction with respect to the fixed housing (401) based on the change in the length of the wire (410). Accordingly, as the first housing (210) and the second housing (220) transition from the unfolded state (e.g., the first state) of the multi-foldable electronic device (200) to the folded state (e.g., the third state), an attractive force may be applied between the first magnet (M1) and the second magnet (M2).

[0122] As described above, the wire (410) is described as being transformed into its original shape when heated to a critical temperature. In one embodiment, the wire (410) may be restored to its original shape based on reaching a preset temperature or lower while in a high temperature state. For example, the wire (410) may be in its original shape memorized in the shape memory alloy before being heated via the electrode (431).

[0123] According to one embodiment, the movable magnet module (400) may include an elastic member (420). In one embodiment, the elastic member (420) may be compressed or stretched based on movement of the movable housing (402) with respect to the fixed housing (401) in a first direction (e.g., direction ① or direction ② of FIG. 9). In one embodiment, the movable housing (402) may be moved in a second direction (e.g., direction ② (e.g., -Y direction) or direction ① (e.g., +Y direction) of FIG. 9) opposite to the first direction with respect to the fixed housing (401) through the elastic restoring force of the elastic member (420) based on restoration of the shape (or length) of the wire (410) as the current flowing to the electrode (431) is cut off.

[0124] In one embodiment, referring to FIG. 8A, the elastic member (400) may be placed in a mounting groove (4021) formed in the moving part housing (402). In one embodiment, the elastic member (4000) may be positioned at least partially in a slit (4011) formed in the fixed housing (401). When a trigger signal is generated in the processor (120) when the first housing (210) and the second housing (220) are in a folded state (e.g., a third state), the movable housing (402) may move in a first direction (e.g., direction ① (e.g., + Y direction) or direction ② (e.g., - Y direction) of FIG. 9) with respect to the fixed housing (401). The elastic member (400) may be compressed by contacting one side of the fixed housing (401) or one side of the movable housing (402) based on the first direction movement of the movable housing (402) with respect to the fixed housing (401). Thereafter, the shape (or length) of the wire (410) is restored as the current flowing to the electrode (431) is cut off, and the movable housing (402) may be elastically Through the elastic restoring force of the absence (420), the fixed housing (401) can move in a second direction opposite to the first direction (e.g., direction ② of FIG. 9 (e.g., - Y direction) or direction ① (e.g., + Y direction)).

[0125] FIG. 10A is a diagram illustrating an embodiment in which a first housing (210) and a second housing (220) are switched from a folded state to an unfolded state based on a user's fingerprint being input to a fingerprint recognition sensor according to an embodiment of the present disclosure. FIG. 10B is a diagram illustrating an embodiment in which a first housing (210) and a second housing (220) are switched from a folded state to an unfolded state based on pressure being applied to a pressure sensor according to an embodiment of the present disclosure.

[0126] According to one embodiment, the multi-foldable electronic device (200) may include a first detection sensor that detects a user's touch. In one embodiment, FIG. 10A may be an embodiment in which a fingerprint recognition sensor is the first detection sensor. In one embodiment, FIG. 10B may be an embodiment in which a pressure sensor (500) is the first detection sensor.

[0127] According to one embodiment, as illustrated in FIG. 10A, when the first detection sensor is a fingerprint recognition sensor, the processor (120) may generate a trigger signal that generates current in the electrode (431) when the user's fingerprint information detected through the fingerprint recognition sensor matches the user's fingerprint information stored in the memory (130). For example, the user's fingerprint may be input to the fingerprint recognition sensor when the first housing (210) and the second housing (220) are in a folded state (e.g., a third state) based on the first folding axis (A1). The processor (120) may generate a trigger signal, which is an operation signal that controls the first substrate (430) to apply current to the wire (410) through the electrode (431), based on the user's fingerprint information identified through the fingerprint recognition sensor matching the user's fingerprint information stored in the memory (130). The wire (410) can be heated as current is applied through the electrode (431) and its length can be changed in a direction parallel to the first folding axis (A1). Based on the change in the length of the wire (410), the movable housing (402) can move in a first direction (e.g., direction ① or ② of FIG. 9) parallel to the first folding axis (A1) with respect to the fixed housing (401). The second magnet (M2) can move in the first direction by a certain length (L) (e.g., length (L) of FIG. 9) together with the movable housing (402) so that the same polarity as that of the first magnet (M1) can face each other. Therefore, as a repulsive force is applied between the first magnet (M1) and the second magnet (M2), the second housing (220) can unfold with respect to the first housing (210) with respect to the first folding axis (A1).

[0128] According to one embodiment, as illustrated in FIG. 10b, when the first detection sensor is a pressure sensor (500), the processor (120) can generate a trigger signal based on the pressure applied to the pressure sensor (500).

[0129] In one embodiment, where the second housing (220) is first folded relative to the first housing (210) and then the third housing (230) is folded relative to the first housing (210), the pressure sensor (500) may be disposed in the first housing (210) such that a sensing pad (e.g., sensing pad (511) of FIG. 11A) for detecting a pressure change may face a sub-display (250) disposed on a second surface (212) of the first housing (210). Additionally, the pressure sensor (500) may be disposed in the second housing (220) such that the sensing pad (511) faces a second rear cover (280) disposed on a fourth surface (222) of the second housing (220).

[0130] In one embodiment, the sub-display (250) may be disposed on the fourth side (222) of the second housing (220) in which the third housing (230) is first folded relative to the first housing (210) and then the second housing (220) is folded relative to the first housing (210). In this case, the pressure sensor (500) may be disposed on the third housing (230) so as to face the third rear cover (290) disposed on the sixth side (232) of the third housing (230). Additionally, the pressure sensor (500) may be disposed on the first housing (210) so as to face the first rear cover (270) disposed on the second side (212) of the first housing (210).

[0131] In one embodiment, a user may press an area of ​​a sub-display (250) corresponding to a pressure sensor (500) or an area of ​​a rear cover (e.g., a first rear cover (270), a second rear cover (280), or a third rear cover (290)) corresponding to a pressure sensor (500). The resistance, capacitance, and / or voltage of the pressure sensor (500) may change based on the pressure applied by the user. The processor (120) may determine the magnitude of the applied pressure based on this. For example, the processor (120) may compare the magnitude of the pressure detected by the pressure sensor (500) with a preset threshold value. The preset threshold value may be stored in the memory (130). The processor (120) may generate a trigger signal that generates a current in the electrode (431) based on whether the magnitude of the pressure detected by the pressure sensor (500) is a threshold value or exceeds the threshold value. For example, the memory (130) may include an instruction that, when the processor (120) is executed, generates a trigger signal based on the magnitude of the pressure detected by the pressure sensor (500) being a threshold value or exceeding the threshold value. The wire (410) may be heated as current is applied, and its length may change in a direction parallel to the first folding axis (A1). Based on the change in the length of the wire (410), the moving unit housing (402) may move in a first direction (e.g., direction ① or ② of FIG. 9) parallel to the first folding axis (A1) with respect to the fixed unit housing (401). The second magnet (M2) may move in the first direction by a certain length (L) (e.g., length (L) of FIG. 9) together with the moving unit housing (402) so that the same polarity as the first magnet (M1) may face each other. Accordingly, as a repulsive force is applied between the first magnet (M1) and the second magnet (M2), the second housing (220) can be unfolded with respect to the first housing (210) with respect to the first folding axis (A1).

[0132] In one embodiment, the pressure sensor (500) may be disposed in at least one of the first housing (210) and the second housing (220) separately from the moving magnet module (400). In one embodiment, the pressure sensor (500) may be disposed in the moving housing (402) of the moving magnet module (400), as illustrated in FIGS. 11A to 11C described below.

[0133] In addition, the processor (120) can detect various actions and generate a trigger signal that generates a current in the electrode (431). For example, the first detection sensor may be a touch sensor formed integrally with the key input device (275) or a touch sensor separately disposed from the key input device (275) in the third side member (233) of the third housing (230) or the second side member (223) of the second housing (220). The processor (120) can detect a user's touch or swiping input inputted to the touch sensor and generate a trigger signal that generates a current in the electrode (431).

[0134] According to one embodiment, the multi-foldable electronic device may include a second detection sensor that detects an angle between the second housing (220) and the third housing (230). According to one embodiment, the second detection sensor may include a first sensor disposed in the first housing (210) and / or a second sensor disposed in the second housing (220), and may include a 6-axis sensor, an acceleration sensor, a gyro sensor, and / or an angle sensor.

[0135] In one embodiment, the processor (120) may be electrically connected to the second detection sensor to determine an angle between the second housing (220) and the third housing (230) detected by the second detection sensor. The processor (120) may compare the angle between the second housing (220) and the third housing (230) detected by the second detection sensor with a pre-stored threshold angle. In one embodiment, the threshold angle may be a value pre-stored in the memory (130). In one embodiment, the threshold angle may be an angle at which the third housing (230) and the second housing (220) do not come into contact when the second housing (220) is unfolded with respect to the first housing (210) while the third housing (230) is unfolded with respect to the second housing (220) at a predetermined angle.

[0136] In one embodiment, the processor (120) may generate a trigger signal, which is an operational signal that controls the first substrate (430) to apply current to the wire (410) through the electrode (431), based on an angle detected by the second detection sensor being equal to or exceeding a threshold angle. For example, the memory (130) may include instructions that, when executed by the processor (120), generate a trigger signal based on an angle detected by the second detection sensor being equal to or exceeding a threshold angle. The wire (410) may be heated as the current is applied, and its length may change in a direction parallel to the first folding axis (A1). Based on the change in the length of the wire (410), the moving unit housing (402) may move in a first direction (e.g., direction ① or ② of FIG. 11A) parallel to the first folding axis (A1) with respect to the fixed unit housing (401). The second magnet (M2) can move in the first direction by a certain length (L) (e.g., length (L) of FIG. 9) together with the moving part housing (402) so that the same polarity as that of the first magnet (M1) can be faced. Accordingly, as a repulsive force is applied between the first magnet (M1) and the second magnet (M2), the second housing (220) can unfold with respect to the first housing (210) with respect to the first folding axis (A1).

[0137] FIG. 11a is a drawing showing a pressure sensor arranged in a moving magnet module according to one embodiment of the present disclosure. FIG. 11b is a drawing showing the arrangement relationship of a pressure sensor, an electrode of a first substrate, and a wire according to one embodiment of the present disclosure. FIG. 11c is a drawing showing a pressure sensor arranged in a rail structure formed in a moving unit housing according to one embodiment of the present disclosure.

[0138] The following description may be an embodiment in which a pressure sensor (500) is placed in a moving magnet module (400). In the following description, the same numbers are used to describe configurations that are identical or similar to the configuration described above.

[0139] According to one embodiment, as illustrated in FIGS. 11A to 11C, the pressure sensor (500) may be disposed on the moving magnet module (400). In one embodiment, the pressure sensor (500) may be partially fixed to the fixed housing (401). In one embodiment, the moving housing (402) may include a rail structure (4024) in which at least a portion of the pressure sensor (500) is accommodated. In one embodiment, the rail structure (4024) may be formed to a size to accommodate the pressure sensor (500).

[0140] According to one embodiment, as illustrated in FIGS. 11A and 11C, the pressure sensor (500) can be fixed to the fixed housing (401). In one embodiment, the pressure sensor (500) can move relative to the movable housing (402) when the movable housing (402) moves in a direction parallel to the first folding axis (A1) relative to the fixed housing (401) by changing the length of the wire (410).

[0141] In one embodiment, the pressure sensor (500) may include a sensing pad (511), a second substrate (512) electrically connected to the sensing pad (511), and a flexible substrate (513) electrically connecting the first substrate (430) and the second substrate (512). In one embodiment, the sensing pad (511) of the pressure sensor (500) may change shape as pressure is applied through a user's touch input. The resistance, capacitance, and / or voltage of the pressure sensor (500) may change according to the shape deformation of the sensing pad (511). The second substrate (512) of the pressure sensor (5000) may convert a physical change applied to the sensing pad (510) into an electrical signal and transmit the electrical signal to the processor (120) through the flexible substrate (513) - the first substrate (430). The processor (120) can compare the magnitude of the pressure detected through the pressure sensor (500) with a preset threshold value. The processor (120) can generate a trigger signal to control the first substrate (430) to generate a current in the electrode (431) based on whether the magnitude of the pressure detected through the pressure sensor (500) is the threshold value or exceeds the threshold value.

[0142] The wire (410) can be heated as current is applied, and its length can change in a direction parallel to the first folding axis (A1). Based on the change in the length of the wire (410), the movable housing (402) can move in a first direction (e.g., direction ① or direction ② of FIG. 11A) parallel to the first folding axis (A1) with respect to the fixed housing (401). The second magnet (M2) can move in the first direction by a certain length (L) (e.g., length (L) of FIG. 11A) together with the movable housing (402) so that the same polarity as that of the first magnet (M1) can face each other. Therefore, as a repulsive force is applied between the first magnet (M1) and the second magnet (M2), the second housing (220) can unfold with respect to the first housing (210) with respect to the first folding axis (A1).

[0143] According to one embodiment, as illustrated in FIG. 11C, the pressure sensor (500) may be disposed on a sliding member (520) (e.g., a sliding substrate, a guide member). In one embodiment, the sliding member (520) may be inserted into a rail structure (4024) of the moving unit housing (402) to guide sliding (e.g., movement) of the pressure sensor (500) with respect to the moving unit housing (402). For example, when the moving unit housing (402) moves in a direction parallel to the first folding axis (A1) with respect to the fixed unit housing (401) based on a trigger signal generated from the processor (120), the sliding member (520) may guide sliding of the pressure sensor (500) with respect to the moving housing (402).

[0144] In one embodiment, the sliding member (520) may be formed of an engineering plastic material, such as polycarbonate, polyamide, or polyacetal, to reduce friction with the moving part housing (402). In one embodiment, the sliding member (520) may be formed of a metal material to ensure a certain level of rigidity.

[0145] According to one embodiment, as illustrated in FIG. 11c, the detection pad (511) of the pressure sensor (500) may be positioned to protrude from the moving unit housing (402) in order to detect a user's touch input. For example, when the pressure sensor (500) is inserted into the rail structure (4024) of the moving unit housing (402), the detection pad (511) of the pressure sensor (500) may protrude from the rail structure (4024) by a certain length (e.g., c in FIG. 11c).

[0146] In one embodiment, in which the second housing (220) is first folded relative to the first housing (210) and then the third housing (230) is folded relative to the first housing (210), the pressure sensor (500) may be disposed on the moving magnet module (400) disposed in the second housing (220). In this case, the detection pad (511) of the pressure sensor (500) may face the second rear cover (280) disposed on the fourth side (222) of the second housing (220) and may be adjacent to the second rear cover (280). The user may touch an area of ​​the second rear cover (280) corresponding to the detection pad (511) when the first housing (210) and the second housing (220) are folded (e.g., the third state). The processor (120) may generate a trigger signal to generate a current in the electrode (431) based on the fact that the pressure detected by the pressure sensor (500) is greater than or equal to a preset pressure when the user touches an area of ​​the second rear cover (280) corresponding to the detection pad (511). In some embodiments, the movable magnet module (400) may be disposed in the first housing (210). In this case, the pressure sensor (500) may be disposed in the movable magnet module (400) and positioned in the first housing (210). The detection pad (511) of the pressure sensor (500) may face the sub-display (250) disposed on the second side (212) of the first housing (210). The user may touch an area of ​​the sub-display (250) corresponding to the detection pad (511) when the first housing (210) and the second housing (220) are folded (e.g., a third state). The processor (120) can generate a trigger signal to generate current in the electrode (431) based on the pressure detected by the pressure sensor (500) being greater than or equal to a preset pressure.

[0147] In one embodiment, in which the third housing (230) is first folded relative to the first housing (210) and then the second housing (220) is folded relative to the first housing (210), the pressure sensor (500) may be disposed on the moving magnet module (400) disposed in the third housing (230). In this case, the detection pad (511) of the pressure sensor (500) may face the third rear cover (290) disposed on the sixth surface (232) of the third housing (220) and may be adjacent to the third rear cover (290). The user may touch an area of ​​the third rear cover (290) corresponding to the detection pad (511) while the first housing (210) and the third housing (230) are folded. The processor (120) may generate a trigger signal to generate a current in the electrode (431) based on the fact that the pressure detected by the pressure sensor (500) is greater than or equal to a preset pressure when the user touches an area of ​​the third rear cover (290) corresponding to the detection pad (511). In some embodiments, the movable magnet module (400) may be disposed in the first housing (210). In this case, the pressure sensor (500) may be disposed in the movable magnet module (400) and positioned in the first housing (210). The detection pad (511) of the pressure sensor (500) may face the first rear cover (270) disposed on the second surface (212) of the first housing (210) and may be adjacent to the first rear cover (270). A user can touch an area of ​​the first rear cover (270) corresponding to the detection pad (511) when the first housing (210) and the third housing (230) are folded. The processor (120) can generate a trigger signal to generate current in the electrode (431) based on the fact that the pressure detected by the pressure sensor (500) is greater than or equal to a preset pressure.

[0148] The wire (410) can be heated as current is applied through the electrode (431) and its length can be changed in a direction parallel to the first folding axis (A1). Based on the change in the length of the wire (410), the movable housing (402) can move in a first direction (e.g., direction ① or ② of FIG. 11A) parallel to the first folding axis (A1) with respect to the fixed housing (401). The second magnet (M2) can move in the first direction by a certain length (L) (e.g., length (L) of FIG. 9) together with the movable housing (402) so that the same polarity as that of the first magnet (M1) can face each other. Therefore, as a repulsive force is applied between the first magnet (M1) and the second magnet (M2), the second housing (220) can unfold with respect to the first housing (210) with respect to the first folding axis (A1).

[0149] In the above description, the movable magnet module (400) is described as being disposed in one of the first housing (210) and the second housing (220). However, the movable magnet module (400) may be disposed in one of the second housing (220) and the third housing (230). In this case, when the second housing (220) and the third housing (230) are folded with respect to the second folding axis (A2), the counter magnet facing the second magnet (M2) of the movable magnet module (400) may be disposed in the other one of the second housing (220) and the third housing (230). When the multi-foldable electronic device (200) is in a completely folded state (e.g., the second state), the second magnet (M2) of the movable magnet module (400) may move in a direction parallel to the second folding axis (A2) by a distance at which a repulsive force acts with the counter magnet based on a trigger signal generated from the processor (120). Therefore, the third housing (230) can be unfolded with respect to the second housing (220) through the repulsive force generated between the second magnet (M2) and the counter magnet.

[0150] There is increasing user demand for expanded displays of foldable electronic devices. Foldable electronic devices may be implemented in the form of a multi-foldable electronic device (200) including a first housing (210), a second housing (220), and a third housing (230).

[0151] The multi-foldable electronic device may include a flexible display (240) disposed at least partially across the first housing, the second housing, and the third housing.

[0152] The multi-foldable electronic device may be configured such that the first housing, the second housing, and the third housing can be operated in an in-folding and / or out-folding manner by using a first hinge assembly (HA1) (e.g., a first hinge module) and a second hinge assembly (HA2) (e.g., a second hinge module).

[0153] The first housing, the second housing, and the third housing of the multi-foldable electronic device can maintain a folded state using at least one magnet (e.g., the first magnet to the fourteenth magnet (M1 to M14)).

[0154] Meanwhile, the multi-foldable electronic device (200) may be configured such that the second housing is first folded relative to the first housing and then the third housing is folded relative to the first housing, or the third housing is first folded relative to the first housing and then the second housing is folded relative to the first housing.

[0155] In an embodiment in which the second housing is first folded relative to the first housing, a user may perform a motion to unfold the second housing relative to the first housing in order to transition the first and second housings from a folded state to an unfolded state. In this case, damage may occur to the flexible display (240) as the user's body (e.g., a fingernail) presses against the flexible display. Similarly, in an embodiment in which the third housing is first folded relative to the first housing, a user may perform a motion to unfold the third housing relative to the first housing in order to transition the first and third housings from a folded state to an unfolded state. In this case, damage may occur to the flexible display as the user's body presses against the flexible display.

[0156] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0157] According to one embodiment of the present disclosure, an electronic device (200) may include a foldable housing including a first housing (210), a second housing (220), and a third housing (230). The electronic device may include a first hinge assembly (HA1) disposed between the first housing and the second housing and rotatably connecting the first housing and the second housing. The electronic device may include a second hinge assembly (HA2) disposed between the first housing and the third housing and rotatably connecting the first housing and the third housing. The electronic device may include a flexible display (240) disposed in the first housing, the second housing, and the third housing. The electronic device may include a first magnet (M1) disposed in one of the first housing and the second housing. The electronic device may include a moving magnet module (400) disposed in the other of the first housing and the second housing, and including a second magnet (M2) facing the first magnet when the first housing and the second housing are folded with respect to the folding axis (A1). The electronic device may include a processor (120) electrically connected to the moving magnet module. A portion of the moving magnet module may move in a direction parallel to the folding axis based on a trigger signal generated from the processor when the first housing and the second housing are folded with respect to the folding axis. The second magnet may move together with a portion of the moving magnet module to exert a repulsive force on the first magnet.

[0158] According to one embodiment of the present disclosure, the movable magnet module may include a fixed housing (401) fixed to the first housing or the second housing. The movable magnet module may include a movable housing (402) that moves with respect to the fixed housing and in which the second magnet is disposed. The movable magnet module may include a shape memory alloy (SMA) material and a wire (410) coupled to the movable housing. The movable magnet module may include an electrode (431) connected to the wire and a substrate (430) disposed on the fixed housing. The substrate may generate a current in the electrode based on the trigger signal. The wire may change in length when the current generated from the electrode is applied.

[0159] According to one embodiment of the present disclosure, the electronic device may further include a first detection sensor that detects a user's touch input and is electrically connected to the processor. The processor may generate the trigger signal based on the touch input detected by the first detection sensor. The movable housing may move a specified distance (L) in a first direction parallel to the folding axis with respect to the fixed housing based on a change in the length of the wire. The second magnet may exert a repulsive force on the first magnet based on the movement of the movable housing in the first direction.

[0160] In one embodiment, the processor can control the substrate to cut off the current flowing to the electrode. The movable housing can move in a second direction opposite to the first direction with respect to the fixed housing by a specified distance (L) based on the restoration of the length of the wire as the current flowing to the electrode is cut off. The second magnet can be arranged so that an attractive force acts on the first magnet when the movable housing is moved in the second direction with respect to the fixed housing.

[0161] In one embodiment, the movable magnet module may include an elastic member (420) that is compressed or stretched based on the first direction movement of the movable housing relative to the fixed housing. The movable housing may move in a second direction opposite to the first direction relative to the fixed housing through the elastic restoring force of the elastic member based on the shape of the wire being restored when the current flowing to the electrode is cut off.

[0162] In one embodiment, the moving part housing may include a hook structure (403) protruding from one side. The wire may be fastened to the hook structure.

[0163] In one embodiment, the moving magnet module may be disposed in an edge region parallel to the folding axis in the first housing. The first magnet may be disposed in an edge region parallel to the folding axis in the second housing.

The processor may generate the trigger signal based on whether the user's fingerprint information detected through the fingerprint recognition sensor matches the fingerprint information stored in the memory.

[0166] In one embodiment, the first detection sensor may be a pressure sensor (500) that is fixed to one of the first housing, the second housing, and the fixed housing and electrically connected to the substrate. The processor may determine the magnitude of pressure applied to the pressure sensor and generate the trigger signal.

[0167] In one embodiment, the moving part housing may include a rail structure (4024) into which at least a portion of the pressure sensor is inserted. The pressure sensor may move along the rail structure based on a change in the length of the wire.

[0168] In one embodiment, the pressure sensor may include a sensing pad (511) that senses a pressure change caused by the user's touch. The sensing pad may protrude relative to the moving unit housing.

[0169] In one embodiment, the electronic device may further include a sliding member (520) on which the pressure sensor is disposed and inserted into the rail structure to guide movement of the pressure sensor relative to the rail structure.

[0170] In one embodiment, the electronic device may further include a first rear cover (270) disposed on a rear surface (212) of the first housing opposite the front surface (211) of the first housing facing the flexible display, and a second rear cover (280) disposed on a rear surface (222) of the second housing opposite the front surface (221) of the second housing facing the flexible display. The sensing pad may face either one of the first rear cover and the second rear cover.

[0171] In one embodiment, the electronic device may further include a sub-display (250) disposed on a back surface opposite the front surface of the first housing or on a back surface opposite the front surface of the second housing. The sensing pad may face the sub-display.

[0172] In one embodiment, the flexible display may include a first folding area (240d) that is folded through the first hinge assembly and a second folding area (240e) that is folded through the second hinge assembly. A first folding width (BW1) of the first folding area is smaller than a second folding width (BW2) of the second folding area, and after the first housing and the second housing are folded, the third housing may be additionally folded.

[0173] In one embodiment, the electronic device may include at least one first additional magnet (M3, M4, M5, M6) disposed in the first housing, at least one second additional magnet (M7, M8, M9, M10, M11) disposed in the second housing, and at least one third additional magnet (M12, M13, M14) disposed in the third housing. When the first housing and the second housing are folded, the first additional magnet and the second additional magnet may face each other and exert an attractive force. After the first housing and the second housing are folded, the third housing may be folded relative to the first housing and face the second housing, and based on this, the second additional magnet and the third additional magnet may face each other and exert an attractive force.

[0174] In one embodiment, the electronic device may be arranged such that at least one of the first additional magnets (M5, M6) disposed in the first housing and at least one of the third additional magnets (M13, M14) disposed in the third housing have the same magnetic direction in an unfolded state of the foldable housing, and a repulsive force is applied when the third housing is folded with respect to the first housing before the second housing.

[0175] In one embodiment, the electronic device may include a second detection sensor that detects an angle between the second housing and the third housing and is electrically connected to the processor. The processor may generate the trigger signal that controls the substrate to generate a current in the electrode based on the angle between the second housing and the third housing detected by the second detection sensor reaching a predetermined angle. The movable housing may move a designated distance (L) in a first direction parallel to the folding axis with respect to the fixed housing based on a change in the length of the wire due to the current generated from the electrode. A repulsive force may be applied between the first magnet and the second magnet based on the movement of the movable housing in the first direction.

[0176] In one embodiment, the processor can control the substrate to cut off the current flowing to the electrode. The movable housing can move in a second direction opposite to the first direction by a specified distance (L) relative to the fixed housing based on the restoration of the shape of the wire as the current flowing to the electrode is cut off.

[0177] According to various embodiments disclosed in this document, the processor (120) can transition two different housings (e.g., the first housing (210) and the second housing (220) of FIG. 2A) from a folded state to an unfolded state. For example, the two different housings can be maintained in a folded state by magnets facing each other in the folded state. When the two different housings are in a folded state, an attractive force may be applied between the magnets (M1, M2). One of the magnets can move in a direction parallel to the folding axis (A1) of the two different housings so as to generate a repulsive force with the other magnet based on a trigger signal generated from the processor. Accordingly, the two different housings can be transitioned from a folded state to an unfolded state as the repulsive force is generated between the different magnets. Accordingly, damage to the flexible display (240) that may occur when a user performs an action of arbitrarily unfolding the two housings can be prevented.
