The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, and / or a global navigation satellite system (GNSS) communication module) and / or a wired communication module (194) (e.g., a local area network (LAN) communication module, and / or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, and / or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

For example, FIG. 2B includes a front view, a first side view, a second side view, a bottom view, and a top view of the electronic device in the second state.

[0063] Referring to FIGS. 2A and 2B , an electronic device (101) may include a housing (200), a flexible display (240), a first hinge assembly (250), and a second hinge assembly (260). The housing (200) may include a first housing part (210), a second housing part (220), and a third housing part (230). The housing (200) may include multiple housing parts (e.g., the first housing part (210), the second housing part (220), and the third housing part (230)) and may be referred to as a foldable housing in that it may be folded multiple times. The electronic device (101) may be referred to as a multi-foldable electronic device when considering the flexible display (240) provided with the housing (200) and / or configured to be folded multiple times. However, the examples are not limited thereto.

[0064] The first housing part (210) can be rotatably coupled to the second housing part (220) by the first hinge assembly (250). The second housing part (220) and the first housing part (210) can be rotated with respect to the first hinge assembly (250). While the first housing part (210) is rotated with respect to the first hinge assembly (250), the second housing part (220) can be rotated with respect to the first hinge assembly (250). For example, when the second housing part (220) and the first housing part (210) are rotated with respect to the first hinge assembly (250), the angular displacement of the second housing part (220) can be substantially equal to the angular displacement (or angular change) of the first housing part (210).

[0065] The third housing part (230) can be rotatably coupled to the second housing part (220) by the second hinge assembly (260). The second housing part (220) and the third housing part (230) can be rotated with respect to the second hinge assembly (260). While the second housing part (220) is rotated with respect to the second hinge assembly (260), the third housing part (230) can be rotated with respect to the second hinge assembly (260). For example, when the second housing part (220) and the third housing part (230) are rotated with respect to the second hinge assembly (260), the angular displacement (or angular change) of the second housing part (220) can be substantially equal to the angular displacement of the third housing part (230).

[0066] The first hinge assembly (250) and the second hinge assembly (260) can change the state of the electronic device. The first hinge assembly (250) and the second hinge assembly (260) can provide (or enable) a first state (101a) of the electronic device (101) (or a first state (101a) of the housing (200)). The first state (101a) of the electronic device (101) (or the first state (101a) of the housing (200)) can be described as an unfolded state of the electronic device (101) (or the housing (200)). Within the first state (101a), the front surface of the first housing part (210), the front surface of the second housing part (220), and the front surface of the third housing part (230) can define the front surface of the electronic device (101). Within the first state (101a), the front of the first housing part (210), the front of the second housing part (220), and the front of the third housing part (230) may face the same direction. Within the first state (101a), the electronic device (101) may provide a large display area of ​​the flexible display (240) to the user.

Within the second state (101b), the front surface of the first housing part (210) and the front surface of the third housing part (230) may face the same direction. For example, within the second state (101b), the front surface of the second housing part (220) may face the front surface of the first housing part (210), and the front surface of the third housing part (230) may face the rear surface of the first housing part (210). Within the second state (101b), the electronic device (101) may be folded to enhance portability.

[0068] The first hinge assembly (250) and the second hinge assembly (260) can provide a third state of the electronic device (101). The third state of the electronic device (101) can be described as a state in which the electronic device (101) is partially folded and partially unfolded (or a single folded state or a half folded state). For example, within the third state, the front surface of the second housing part (220) and the front surface of the third housing part (230) may face the same direction, and the front surface of the first housing part (210) and the front surface of the second housing part (220) may face opposite directions. For example, within the third state, the first housing part (210) and the second housing part (220) may be folded, and the second housing part (220) and the third housing part (230) may be unfolded.

[0069] A flexible display (240) can at least partially define the appearance of an electronic device (101). The flexible display (240) can be partially disposed within a housing (200).

The flexible display (240) can include a first display portion (241), a second display portion (242), a third display portion (243), a fourth display portion (244), and a fifth display portion (245). The first display portion (241) of the flexible display (240) can be disposed on a front surface of the first housing part (210). The second display portion (242) of the flexible display (240) can be disposed on a front surface of the second housing part (220). The third display portion (243) of the flexible display (240) may be disposed on the front of the third housing part (230). The fourth display portion (244) of the flexible display (240) may be disposed between the first display portion (241) and the second display portion (242) of the flexible display (240). For example, the fourth display portion (244) of the flexible display (240) may be disposed on the first hinge assembly (250) connecting the first housing part (210) and the second housing part (220). The fifth display portion (245) of the flexible display (240) may be disposed between the second display portion (242) and the third display portion (243) of the flexible display (240). For example, the fifth display part (245) of the flexible display (240) may be placed on the second hinge assembly (260) connecting the second housing part (220) and the third housing part (230).

[0070] In the first state (101a), the entire display area of ​​the flexible display (240) can be seen from the front of the housing (200). For example, the first display portion (241), the second display portion (242), the third display portion (243), the fourth display portion (244), and the fifth display portion (245) of the flexible display (240) can be visually exposed. The electronic device (101) can provide a large display area to the user that includes the first display portion (241), the second display portion (242), the third display portion (243), the fourth display portion (244), and the fifth display portion (245). In the second state (101b), the display area of ​​the flexible display (240) can be invisible. For example, the first display portion (241), the second display portion (242), the third display portion (243), the fourth display portion (244), and the fifth display portion (245) of the flexible display (240) may not be visually exposed. In the third state, the display area of ​​the flexible display (240) may be partially visible from the front of the third housing part (230). For example, the third display portion (243) may be visually exposed, and the first display portion (241) and the second display portion (242) may not be visually exposed.

[0071] As a non-limiting example, when the flexible display (240) is used to display a screen within a first state (101a) of the electronic device (101), all parts of the flexible display (240) (e.g., the first display portion (241), the second display portion (242), the third display portion (243), the fourth display portion (244), and the fifth display portion (245)) may be activated. As a non-limiting example, within a second state (101b), all parts of the flexible display (240) (e.g., the first display portion (241), the second display portion (242), the third display portion (243), the fourth display portion (244), and the fifth display portion (245)) may be deactivated. As a non-limiting example, within the third state of the electronic device (101), when the flexible display (240) is used to display a screen, the third display portion (243) may be activated, and other portions of the flexible display (240) (e.g., the first display portion (241), the second display portion (242), the fourth display portion (244), and the fifth display portion (245)) may be deactivated.

[0072] The first hinge assembly (250) and the second hinge assembly (260) may face substantially the same direction as the direction in which the first display portion (241) of the flexible display (240), the second display portion (242) of the flexible display (240), and the third display portion (243) of the flexible display (240) face. In the first state (101a), the fourth display portion (244) and the fifth display portion (245) may be arranged in substantially the same horizontal plane as the first display portion (241), the second display portion (242), and the third display portion (243).

[0073] The first hinge assembly (250) and the second hinge assembly (260) can provide a second state (101b) of the electronic device (101). Within the second state (101b), the second display portion (242) of the flexible display (240) can face the first display portion (241) of the flexible display (240), and the third display portion (243) of the flexible display (240) can face the back of the first housing part (210). Within the second state (101b), the fourth display portion (244) of the flexible display (240) can be folded such that the first display portion (241) of the flexible display (240) and the second display portion (242) of the flexible display (240) face different directions. Within the second state (101b), the fifth display portion (245) of the flexible display (240) can be folded so that the second display portion (242) of the flexible display (240) and the third display portion (243) of the flexible display (240) face different directions.

[0074] Within the second state (101b), the first housing part (210) may be disposed between the second housing part (220) and the third housing part (230). Within the second state (101b), the fifth display portion (245) of the flexible display (240) disposed on the second hinge assembly (260) may partially face the side of the first housing part (210). For example, in order to provide visual information to the user within the second state (101b), a sub-display may be additionally disposed on the rear of the second housing part (220). However, the present disclosure is not limited thereto.

[0075] FIG. 3A is a top plan view of an exemplary electronic device in a first state with the flexible display removed. FIG. 3B is a rear view of the exemplary electronic device in a first state with the back cover and display removed.

[0076] Referring to FIGS. 3A and 3B, the electronic device (101) may include a first hinge assembly (250) and a second hinge assembly (260). A first width (w1) of the first hinge assembly (250) may be narrower than a second width (w2) of the second hinge assembly (260). A difference between the first width (w1) of the first hinge assembly (250) and the second width (w2) of the second hinge assembly (260) may be equal to or greater than a thickness of the first housing part (210). For example, the second hinge assembly (260) may have a second width (w2) that is wider than the first width (w1) such that the first housing part (210) is positioned between the second housing part (220) and the third housing part (230) in the second state (101b). The first hinge assembly (250) may be referred to as a narrow hinge structure in terms of having a narrower width than the second hinge assembly (260). The second hinge assembly (260) may be referred to as a wide hinge structure in terms of having a wider width than the first hinge assembly (250).

[0077] A first hinge assembly (250) may include a first set of gears (251), a first hinge plate (252), and a second hinge plate (253). The first hinge plate (252) may be coupled to a first support portion (211) of a first housing part (210). The second hinge plate (253) may be coupled to a second support portion (221) of a second housing part (220). The gears included in the first set of gears (251) may be configured to rotate the first hinge plate (252) and the second hinge plate (253). For example, the gears included in the first set of gears (251) can rotate the second hinge plate (253) (or the second housing part (220)) in conjunction with the rotation of the first hinge plate (252) (or the first housing part (210)). After the first hinge plate (252) (or the first housing part (210)) is rotated, the gears included in the first set of gears (251) can rotate in accordance with the rotation of the first hinge plate (252) (or the first housing part (210)). The second hinge plate (253) (or the second housing part (220)) can rotate in conjunction with the rotation of the first hinge plate (252) in accordance with the rotation of the gears included in the first set of gears (251).

[0078] The second hinge assembly (260) may include a second set of gears (261), a third hinge plate (262), a fourth hinge plate (263), and a support plate (264). The third hinge plate (262) may be coupled to a second support portion (221) of the second housing part (220). The fourth hinge plate (263) may be coupled to a third support portion (231) of the third housing part (230). The gears included in the second set of gears (261) may be configured to rotate the third hinge plate (262) and the fourth hinge plate (263). For example, the gears included in the second set of gears (261) can rotate the fourth hinge plate (263) (or the third housing part (230)) in conjunction with the rotation of the third hinge plate (262) (or the second housing part (220)). After the third hinge plate (262) (or the second housing part (220)) is rotated, the gears included in the second set of gears (261) can rotate in accordance with the rotation of the third hinge plate (262) (or the second housing part (220)). The fourth hinge plate (263) (or the third housing part (230)) can rotate in conjunction with the rotation of the third hinge plate (262) in accordance with the rotation of the gears included in the second set of gears (261).

[0079] The electronic device (101) may include a first printed circuit board (271), a second printed circuit board (272), and a third printed circuit board (273). Each of the printed circuit boards (e.g., the first printed circuit board (271), the second printed circuit board (272), and the third printed circuit board (273)) may be equipped with various hardware components.

[0080] A first printed circuit board (271) may be placed on a first support portion (211) of a first housing part (210). Hardware components within the first housing part (210) may be placed on the first printed circuit board (271). A second printed circuit board (272) may be placed on a second support portion (221) of a second housing part (220). Hardware components within the second housing part (220) may be placed on the second printed circuit board (272). A third printed circuit board (273) may be placed on a third support portion (231) of a third housing part (230). Hardware components within the third housing part (230) (e.g., a rear camera (275)) may be placed on the third printed circuit board (273).

[0081] The hardware components placed on the first printed circuit board (271) can support or operate independently of the hardware components placed on the second printed circuit board (272) and / or the hardware components placed on the third printed circuit board (273).

[0082] The hardware components arranged on the second printed circuit board (272) may support or operate independently of the hardware components arranged on the first printed circuit board (271) or the third printed circuit board (273). The hardware components arranged on the second printed circuit board (272) may include a speaker, a front camera, and / or a display driving circuit.

[0083] Hardware components arranged on the third printed circuit board (273) may include at least one processor including a processing circuit, a memory including one or more storage media, a communication circuit, and a rear camera (275). The rear camera (275) may be exposed through a structure (e.g., an opening) on ​​the rear of the third housing part (230).

[0084] The electronic device (101) may further include batteries. Each of the batteries may be attached to support portions (e.g., a first support portion (211), a second support portion (221), and a third support portion (231)) included in housing portions (e.g., a first housing portion (210), a second housing portion (220), and a third housing portion (230)). The support portions (211, 221, 231) may support rechargeable batteries.

[0085] The housing (200) may include protective covers (e.g., a first protective cover (215), a second protective cover (225), and a third protective cover (235)). For example, the protective covers (e.g., the first protective cover (215), the second protective cover (225), and the third protective cover (235)) may form edges of the electronic device (101) within the first state (101a). For example, the first housing part (210) may include a first protective cover (215) that at least partially surrounds the first support portion (211). The second housing part (220) may include a second protective cover (225) that at least partially surrounds the second support portion (221). The third housing part (230) may include a third protective cover (235) that at least partially surrounds the third support portion (231). The second protective cover (225) may be positioned between the first protective cover (215) and the third protective cover (235) within the first state (101a) of the electronic device (101). The protective covers (e.g., the first protective cover (215), the second protective cover (225), and the third protective cover (235)) may be referred to as a peripheral portion and / or deco of the housing (200) in that they are positioned along the edge of the electronic device (101) to protect the edge of the flexible display (240), but embodiments of the present disclosure are not limited thereto.

[0086] Although the first housing part (210) and the third housing part (230) have been described as rotating in opposite directions with respect to the second housing part (220), this is not limited thereto. For example, during the change from the first state (101a) to the second state (101b), the first housing part (210) may rotate counterclockwise with respect to the second housing part (220), and the third housing part (230) may rotate counterclockwise with respect to the second housing part (220). As the first housing part (210) and the third housing part (230) rotate in the same direction, a portion of the display area of ​​the flexible display (240) within the second state may be visually exposed. However, the embodiments of the present disclosure are not limited thereto, and for example, while changing from the first state (101a) to the second state (101b), the first housing part (210) may rotate clockwise with respect to the second housing part (220), and the third housing part (230) may rotate counterclockwise with respect to the second housing part (220).

[0087] Figure 4a illustrates an exemplary electronic device in a first state. Figure 4b illustrates an exemplary electronic device.

[0088] Referring to FIGS. 4A and 4B, the electronic device (101) may include a housing (200) including a first housing part (210), a second housing part (220), and a third housing part (230). The electronic device (101) may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3A) that rotatably couples the first housing part (210) and the second housing part (220), and a second hinge assembly (e.g., the second hinge assembly (260) of FIG. 3A) that rotatably couples the second housing part (220) and the third housing part (230). The electronic device (101) may include a flexible display (240) including display portions (e.g., a first display portion (241), a second display portion (242), a third display portion (243), a fourth display portion (244), and a fifth display portion (245)).

[0089] The flexible display (240) can be coupled to the housing (200). The flexible display (240) can be partially bent by the first hinge assembly (250) and the second hinge assembly (260). For example, the flexible display (240) can be accommodated in the first housing part (210), the second housing part (220), and the third housing part (230). For example, the first display part (241) can be coupled to the first housing part (210). The second display part (242) can be coupled to the second housing part (220). The third display part (243) can be coupled to the third housing part (230). For example, the fourth display part (244) can be configured to be deformed by the first hinge assembly (250). For example, the fifth display portion (245) may be configured to be deformed by the second hinge assembly (260). For example, referring to FIGS. 3A and 3B together, in order to provide the second state (101b) (or multi-folded state) of the electronic device (101), the width (or area) of the fifth display portion (245) may be greater than the width (or area) of the fourth display portion (244). However, embodiments of the present disclosure are not limited thereto.

[0090] The electronic device (101) may include a first hinge cover (410) that surrounds a portion of a first hinge assembly (250), and a second hinge cover (420) that surrounds a portion of a second hinge assembly (260). For example, the first hinge cover (410) may be positioned below a fourth display portion (244). The first hinge assembly (250) may be positioned at least partially between the first hinge cover (410) and the fourth display portion (244). For example, the second hinge cover (420) may be positioned below a fifth display portion (245). The second hinge assembly (260) may be positioned at least partially between the second hinge cover (420) and the fifth display portion (245). For example, referring to FIGS. 3a and 3b together, the first hinge cover (410) and the second hinge cover (420) may be more exposed to the outside of the electronic device (101) in the second state (101b) of the electronic device (101) than in the first state (101a) of the electronic device (101). For example, while the electronic device (101) changes from the first state (101a) to the second state (101b), the outer surface of the first hinge cover (410) may be at least partially covered by the first housing part (210) and the second housing part (220). For example, while the electronic device (101) changes from the first state (101a) to the second state (101b), the outer surface of the second hinge cover (420) may be at least partially covered by the second housing part (220) and the third housing part (230). However, the embodiment of the present disclosure is not limited thereto. The electronic device (101) can reduce damage to the hinge assemblies (250, 260) due to external impact within the multiple states of the electronic device (101) by including the hinge covers (410, 420).

[0091] Referring to FIGS. 2A and 3B together, within a first state (101a) of the electronic device (101), the first housing part (210) and the second housing part (220) may be in contact with each other. The second housing part (220) and the third housing part (230) may be spaced apart from each other within the first state (101a) so as to accommodate the first housing part (210) between the second housing part (220) and the third housing part (230) within the second state (101b) of the electronic device (101). For example, the width of the first hinge cover (410) surrounding the first hinge assembly (250) referred to as a narrow hinge may be smaller than the width of the second hinge cover (420) surrounding the second hinge assembly (260) referred to as a wide hinge. Since the width of the second hinge cover (420) may be relatively larger than the width of the first hinge cover (410), the second housing part (220) and the third housing part (230) partially surrounding the second hinge cover (420) within the first state (101a) of the electronic device (101) may be spaced apart from each other.

[0092] For example, as illustrated in FIGS. 4A and 4B , in a first state (101a) of the electronic device (101), the first housing part (210) and the second housing part (220) may be in contact with each other. For example, the first housing part (210) and the second housing part (220) may be configured to be in contact with each other before the first hinge cover (410) is in contact with the first housing part (210) and the second housing part (220). The first housing part (210) and the second housing part (220) may first support each other before being in contact with the first hinge cover (410), thereby protecting the first hinge cover (410) (or the first hinge assembly (250)) that is at least partially surrounded by the first housing part (210) and the second housing part (220).

[0093] For example, in the first state (101a) of the electronic device (101), the second housing part (220) and the third housing part (230) may be spaced apart from each other. In a comparative example, since the second housing part (220) and the third housing part (230) are spaced apart from each other, as illustrated in FIG. 4b, when the electronic device (101) performs a folding operation or an external impact is applied, the second hinge cover (420) (or the second hinge assembly (260)) may be damaged by the housing parts (220, 230). For example, in the comparative example, as illustrated in FIG. 4b, the fifth display portion (245) may be damaged by over-rotation of the third housing part (230) relative to the second housing part (220) while the electronic device (101) performs a folding operation, or the second hinge cover (420) and / or the second hinge assembly (260) may be damaged by contact between the housing parts (220, 230) and the second hinge cover (420). To avoid the problem of the comparative example, the electronic device (101) may be provided with a structure for supporting the second housing part (220) and the third housing part (230) that are spaced apart from each other so as to protect the second hinge cover (420) having a relatively wide width and / or the second hinge assembly (260) covered by the second hinge cover (420). The above structure is explained through exemplary cities below in Fig. 5a.

[0094] FIG. 5A illustrates a portion of an exemplary electronic device in a first state. FIG. 5B illustrates a portion of an exemplary electronic device in a second state. FIG. 5C illustrates a portion of a second hinge cover of the exemplary electronic device. FIGS. 5D, 5E, 5F, and 5G illustrate structures for moving a stopper of the exemplary electronic device.

[0095] Referring to FIGS. 5A, 5B, 5C, 5D, 5E, 5F, and 5G, the electronic device (101) may include a housing (200) including a first housing part (210), a second housing part (220), and a third housing part (230). The electronic device (101) may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3A) that rotatably couples the first housing part (210) and the second housing part (220). The electronic device (101) may include a second hinge assembly (260) that rotatably couples the second housing part (220) and the third housing part (230). The second housing part (220) and the third housing part (230) may be spaced apart from each other within the first state (101a) of the electronic device (101). However, the embodiments of the present disclosure are not limited thereto, and for example, the electronic device (101) illustrated and described in FIGS. 5A to 5G may include structures and / or configurations illustrated and described in FIGS. 2A to 4B. In addition, hereinafter, redundant descriptions of structures and / or configurations having the same reference numerals as the structures and / or configurations illustrated and described in FIGS. 2A to 4B may be omitted.

[0096] The electronic device (101) may include a stopper (510) positioned between the second housing part (220) and the third housing part (230) to support the second housing part (220) and the third housing part (230) within a first state (101a) of the electronic device (101). For example, the stopper (510) may be positioned between a side surface (220a) of the second housing part (220) and a side surface (230a) of the third housing part (230) within the first state (101a) of the electronic device (101). For example, the stopper (510) may be in contact with the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101). The stopper (510) may be pressed by the second housing part (220) and the third housing part (230) within the first state (101a). The stopper (510) may support the second housing part (220) through a repulsive force due to pressure from the second housing part (220). The stopper (510) may support the third housing part (230) through a repulsive force due to pressure from the third housing part (230). For example, the stopper (510) may be at least partially exposed to the outside of the electronic device (101) within the first state (101a) of the electronic device (101). The stopper (510) may be disposed between a gap between the second housing part (220) and the third housing part (230), or may be exposed to the outside through the gap. For example, the stopper (510) can be interposed between the second housing part (220) and the third housing part (230) in the first state (101a) of the electronic device (101), thereby preventing the third housing part (230) from being excessively rotated relative to the second housing part (220) in the first state (101a).The above stopper (510) can prevent over-rotation of the third housing part (230) with respect to the second housing part (220), thereby reducing damage to the second hinge cover (420) (or the second hinge assembly (260)) due to over-rotation.

[0097] The second housing part (220) and the third housing part (230) may be configured to contact the stopper (510) before the second hinge cover (420) contacts the second housing part (220) and the third housing part (230). For example, referring to FIG. 4A together, in a first state (101a) of the electronic device (101), the first housing part (210) and the second housing part (220) may contact each other before the first hinge cover (410) contacts the first housing part (210) and the second housing part (220), thereby protecting the first hinge cover (410) (or the first hinge assembly (250)). For example, unlike FIGS. 4A and 4B, in the first state (101a) of the electronic device (101), the second housing part (220) and the third housing part (230) come into contact with the stopper (510) before the second hinge cover (420) comes into contact with the second housing part (220) and the third housing part (230), thereby reducing damage to the second hinge cover (420) (or the second hinge assembly (260)) due to contact between the housing parts (220, 230) and the second hinge cover (420).

[0098] The second hinge cover (420) may include a through hole (520) for receiving a stopper (510). The stopper (510) may be configured to protrude from the outer surface (425) of the second hinge cover (420) through the through hole (520) so as to come into contact with the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101). The stopper (510) may be configured to be disposed within the through hole (520) so as to form a continuous surface together with the outer surface (425) of the second hinge cover (420) within the second state (101b) of the electronic device (101).

[0099] For example, the stopper (510) may be movable relative to the second hinge cover (420). For example, the stopper (510) may be interlocked with the second hinge assembly (260) to be slidable relative to the second hinge cover (420) while the state of the electronic device (101) changes. For example, the stopper (510) may be movable in a direction (501) and a direction (502) opposite to the direction (501) relative to the second hinge cover (420) (or the through hole (520)) according to the rotation of the third housing part (230) relative to the second housing part (220), as illustrated.

[0100] For example, the through hole (520) of the second hinge cover (420) may partially expose the stopper (510) to the outside of the electronic device (101). For example, the through hole (520) may be formed in a part of the second hinge cover (420) that is exposed to the outside of the electronic device (101) in the first state (101a) of the electronic device (101). For example, the stopper (510) may be coupled to the through hole (520) so as to be slidable within the through hole (520). For example, the through hole (520) may have a length in a direction corresponding to directions (501, 502) in which the stopper (510) moves in order to guide the movement direction of the stopper (510).

[0101] For example, in the first state (101a) of the electronic device (101), the stopper (510) may protrude from the outer surface (425) of the second hinge cover (420) through the through hole (520). For example, while the electronic device (101) changes from the second state (101b) to the first state (101a), the stopper (510) may move in the direction (501) from the outer surface (425) of the second hinge cover (420). The stopper (510) may protrude from the outer surface (425) in the first state (101a) to at least partially face the second housing part (220) (or side surface (220a)) and the third housing part (230) (or side surface (230a)). The above stopper (510) may be configured to support the housing parts (220, 230) by protruding from the outer surface (425) of the second hinge cover (420) at least partially through the through hole (520) within the first state (101a). However, the embodiment of the present disclosure is not limited thereto.

[0102] For example, in the second state (101b) of the electronic device (101), the stopper (510) may be positioned inside the through hole (520) to form a continuous surface with the outer surface (425) of the second hinge cover (420). For example, the outer surface (510a) of the stopper (510) may cover the inlet of the through hole (520) in the second state (101b) of the electronic device (101). The outer surface (510a) of the stopper (510) may have a shape corresponding to the inlet of the through hole (520), to form a continuous surface with the outer surface (425) of the second hinge cover (420). For example, while the electronic device (101) changes from the first state (101a) to the second state (101b), the stopper (510) may form a continuous surface with the outer surface (425) of the second hinge cover (420) by moving in the direction (502). The stopper (510) may provide the user of the electronic device (101) with an aesthetic sense of the electronic device (101) in the second state (101b) by forming a continuous surface with the second hinge cover (420) in the second state (101b). However, the embodiments of the present disclosure are not limited thereto.

[0103] The outer surface (425) of the second hinge cover (420) may include a vertical surface (425a), a horizontal surface (425b) perpendicular to the vertical surface (425a), and a curved surface (425c) extending from the vertical surface (425a) to the horizontal surface (425b). A through hole (520) may be formed in a portion of the vertical surface (425a), a portion of the horizontal surface (425b), and a portion of the curved surface (425c), thereby exposing the stopper (510) to the outside of the electronic device (101).

[0104] For example, the vertical surface (425a) and the horizontal surface (425b) can be formed to be perpendicular to each other. The curved surface (425c) can be at least partially curved to connect the vertical surface (425a) and the horizontal surface (425b). For example, a part of the vertical surface (425a), a part of the horizontal surface (425b), and a part of the curved surface (425c) can be exposed to the outside of the electronic device (101) by the second housing part (220) and the third housing part (230), which are spaced apart from each other within the first state (101a) of the electronic device (101). The through hole (520) of the second hinge cover (420) may be formed in a portion of the vertical surface (425a), a portion of the horizontal surface (425b), and a portion of the curved surface (425c), thereby allowing the stopper (510) to protrude outwardly within the first state (101a). For example, the outer surface (510a) of the stopper (510) may have an at least partially curved shape to form a continuous surface with the curved surface (425c) within the second state (101b) of the electronic device (101), but the present disclosure is not limited thereto.

[0105] For example, the stopper (510) may be brought into contact with the side surface (220a) of the second housing part (220) and the side surface (230a) of the third housing part (230) facing the side surface (220a) of the second housing part (220) in the first state (101a) of the electronic device (101). For example, the stopper (510) may be brought into contact with corner regions of the side surface (220a) of the second housing part (220) and the side surface (230a) of the third housing part (230) by tilting the directions (501, 502) (movement directions) in which the stopper (510) moves with respect to the directions (503, 504) parallel to the direction in which the vertical surface (425a) of the second hinge cover (420) faces. By coming into contact with the above corner areas, the stopper (510) can improve support to the housing parts (220, 230) within the first state (101a) of the electronic device (101).

[0106] The second hinge cover (420) may include a guide rail (521) protruding from the inner surface (520a) of the through hole (520) to guide the position of the stopper (510). The stopper (510) may include a guide groove (511) slidably coupled to the guide rail (521) so that the stopper (510) moves in a direction (501) and a direction (502) opposite to the direction (501) with respect to the second hinge cover (420). For example, a pair of guide rails (521) may protrude from the inner surface (520a) of the through hole (520) of the second hinge cover (420) to face each other, as illustrated in FIG. 5c. For example, the guide rail (521) may have a length according to the directions (501, 502) in order to guide the movement of the stopper (510) in the directions (501, 502). For example, the guide groove (511) may have a shape corresponding to the guide rail (521) of the second hinge cover (420). The guide groove (511) may be formed on the side of the stopper (510) to be paired with the guide rail (521), for example. For example, the guide groove (511) may have a length according to the directions (501, 502) in which the stopper (510) moves. For example, the guide groove (511) can be slidably coupled to the guide rail (521), thereby movably coupling the stopper (510) to the second hinge cover (420) (or through hole (520)). However, the embodiment of the present disclosure is not limited thereto.

[0107] The electronic device (101) may include a sliding member (530) for moving the stopper (510). The sliding member (530) may include a first part (531) coupled with the stopper (510), a second part (e.g., the second part (532) of FIG. 6C) configured to slide by rotation of the third housing part (230) relative to the second housing part (220), and a third part (533) extending from the first part (531) to the second part (532) and providing a driving force for moving the stopper (510) to the first part (531) through the second part (532).

[0108] For example, the sliding member (530) may be provided as a part of the second hinge assembly (260) or may be movably coupled to the second hinge assembly (260). For example, the sliding member (530) may be positioned at least partially within the housing (200) between the second housing part (220) and the third housing part (230). For example, the sliding member (530) may move the stopper (510) in the directions (501, 502) by axially moving in the directions (503, 504) through the rotation of the third housing part (230) relative to the second housing part (220). For example, the first part (531) of the sliding member (530) may be coupled with the stopper (510) and disposed within the through hole (520) together with the stopper (510). For example, the third part (533) of the sliding member (530) can move the first part (531) by extending from the first part (531) that is coupled to the stopper (510). The third part (533) can provide axial movement to the first part (531) by having a length in directions (503, 504) that are, for example, the movement direction of the sliding member (530). The axial movement of the sliding member (530) through the second part (532) of the sliding member (530) by the rotation of the third housing part (230) with respect to the second housing part (220) will be described below. The electronic device (101) can be configured to provide a variety of user experiences to the user by including a sliding member (530) that moves the stopper (510) while the state of the electronic device (101) changes, and to support the housing parts (220, 230) through the stopper (510) within the first state (101a).

[0109] The stopper (510) may include a guide hole (512). The first part (531) of the sliding member (530) may include a coupling hole (531a). The electronic device (101) may further include a coupling pin (540) penetrating the guide hole (512) and the coupling hole (531a) so that the first part (531) is slidably coupled to the stopper (510). For example, referring to FIGS. 5d and 5e, the first part (531) of the sliding member (530) may be positioned between the guide hole (512) of the stopper (510). The coupling pin (540) can slidably couple the first part (531) and the stopper (510) by penetrating through the guide hole (512) and the coupling hole (531a) of the first part (531). For example, the electronic device (101) may include a fixing pin (550) to prevent the coupling pin (540) from being detached from the first part (531) and the stopper (510). The fixing pin (550) may be fastened to one end of the coupling pin (540).

[0110] For example, referring to FIGS. 5A and 5B, the first part (531) of the sliding member (530) can be slidably coupled in the directions (505, 506) to the guide hole (512) of the stopper (510) via the coupling pin (540).

[0111] For example, while the electronic device (101) is changed from the second state (101b) to the first state (101a), the sliding member (530) can be slid in the direction (503) with respect to the second hinge cover (420). By the first part (531) of the sliding member (530) sliding in the direction (503), the coupling pin (540) can be moved in the direction (505) along the guide hole (512). By the stopper (510) being pushed by the coupling pin (540) moving in the direction (505), the stopper (510) can be moved in the direction (501) along the guide rail (521). The above stopper (510) can be protruded from the outer surface (425) of the second hinge cover (420) by moving in the above direction (501).

[0112] For example, while the electronic device (101) is changed from the first state (101a) to the second state (101b), the sliding member (530) can be slid in the direction (504) with respect to the second hinge cover (420). By the first part (531) of the sliding member (530) sliding in the direction (504), the coupling pin (540) can be moved in the direction (506) along the guide hole (512). By the stopper (510) being pulled by the coupling pin (540) moving in the direction (506), the stopper (510) can be moved in the direction (502) along the guide rail (521). The above stopper (510) may be positioned within the through hole (520) so as to form a continuous surface with the outer surface (425) of the second hinge cover (420) by moving in the direction (502). However, the present disclosure is not limited thereto.

[0113] The configurations of the electronic device (101) for moving the stopper (510) through the rotation of the third housing part (230) with respect to the second housing part (220) are described below.

[0114] Figures 6a and 6b illustrate a second hinge assembly and a second hinge cover of an exemplary electronic device. Figure 6c illustrates a portion of an exemplary electronic device in a first state. Figure 6d illustrates a portion of an exemplary electronic device in a second state. Figure 6e illustrates a portion of an exemplary electronic device in a first state. Figure 6f illustrates a portion of an exemplary electronic device in a second state.

[0115] Referring to FIGS. 6A, 6B, 6C, 6D, 6E, and 6F, the electronic device (101) may include a housing (200) including a first housing part (210), a second housing part (220), and a third housing part (230). The electronic device (101) may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3A) that rotatably couples the first housing part (210) and the second housing part (220). The electronic device (101) may include a second hinge assembly (260) that rotatably couples the second housing part (220) and the third housing part (230). The second housing part (220) and the third housing part (230) may be spaced apart from each other within the first state (101a) of the electronic device (101). The electronic device (101) may include a stopper (510) positioned between the second housing part (220) and the third housing part (230) to support the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101). However, the embodiments of the present disclosure are not limited thereto, and for example, the electronic device (101) illustrated and described in FIGS. 6A to 6F may include structures and / or configurations illustrated and described in FIGS. 2A to 5G. Additionally, in the following, redundant descriptions of structures and / or configurations having the same reference numerals as the structures and / or configurations illustrated and described in FIGS. 2a to 5g may be omitted.

[0116] Referring to FIGS. 6A and 6B, hinge portions (260a, 260b, 260c) of the second hinge assembly (260) are exemplarily illustrated. The hinge portions (260a, 260b, 260c) may be referred to as any one of a hinge, a hinge module, and a hinge structure that rotatably couple the second housing part (220) and the third housing part (230), respectively. For example, the first hinge portion (260a) and the second hinge portion (260b) may be disposed at longitudinal end portions of the second hinge cover (420) (or the second hinge assembly (260)). For example, the third hinge portion (260c) may be positioned between the first hinge portion (260a) and the second hinge portion (260b). The third hinge portion (260c) may be positioned adjacent to the second hinge portion (260b) and linked to the second hinge portion (260b), for example. The third hinge portion (260c) may be spaced apart from the first hinge portion (260a). For example, an electronic component (e.g., a flexible printed circuit board) of the electronic device (101) may pass across or be positioned through the spaced gap between the third hinge portion (260c) and the first hinge portion (260a). However, the embodiment of the present disclosure is not limited thereto, and it should be noted that the second hinge assembly (260) may include a plurality of hinge parts including hinge parts (260a, 260b, 260c), and the arrangement relationship therebetween is not intended to be limited. In addition, the detailed structures of the second hinge assembly (260), which will be described below, may be included in any one of the hinge parts (260a, 260b, 260c), or may be included in all of the hinge parts (260a, 260b, 260c). For example, as illustrated, the stopper (510) may be arranged at the longitudinal ends of the second hinge cover (420) and may be interlocked with the first hinge part (260a) and the second hinge part (260b), respectively.However, the embodiments of the present disclosure are not limited thereto. Hereinafter, the structure of the second hinge assembly (260) for moving the stopper (510) is illustrated and described.

[0117] Referring to FIGS. 6c, 6d, 6e, and 6f, the sliding member (530) may include a first part (e.g., the first part (531) of FIG. 5d) coupled with the stopper (510), a second part (532) configured to slide by rotation of the third housing part (230) relative to the second housing part (220), and a third part (533) extending from the first part (531) to the second part (532) and providing a driving force to the first part (531) to move the stopper (510) through the second part (532).

[0118] The second hinge assembly (260) may include at least one hinge plate (610) rotatably connecting the second housing part (220) and the third housing part (230). The at least one hinge plate (610) may include a first hinge plate (611) coupled to the second housing part (220) and a second hinge plate (612) coupled to the third housing part (230). The second housing part (220) may include a first plate (621) coupled to the first hinge plate (611) so as to rotate together with the first hinge plate (611). The third housing part (230) may include a second plate (622) coupled to the second hinge plate (612) so as to rotate together with the second hinge plate (612).

[0119] For example, the first hinge plate (611) can rotatably couple the second hinge assembly (260) and the second housing part (220). The second hinge plate (612) can rotatably couple the second hinge assembly (260) and the third housing part (230). Through the hinge plates (611, 612), the third housing part (230) can rotate with respect to the second housing part (220) with respect to the second hinge assembly (260) (or the second hinge cover (420)). For example, the first plate (621) can be a portion of the second housing part (220) that is coupled with the second hinge assembly (260) (or the first hinge plate (611)). The second plate (622) may be a portion that is coupled with the second hinge assembly (260) (or the second hinge plate (612)) of the third housing part (230). For example, according to some embodiments, the first hinge plate (611) may be rotatably coupled to the first plate (621) via a shaft. The second hinge plate (612) may be rotatably coupled to the second plate (622) via a shaft. Since the first hinge plate (611) is rotatably coupled to the first plate (621), the rotational axis of the first hinge plate (611) may be offset with respect to the rotational axis of the first plate (621). Since the second hinge plate (612) is rotatably coupled to the second plate (622), the rotational axis of the second hinge plate (612) can be offset with respect to the rotational axis of the second plate (622). However, the embodiments of the present disclosure are not limited thereto.

[0120] The first plate (621) may include a first spiral portion (621a). The second plate (622) may include a second spiral portion (622a). The second portion (532) of the sliding member (530) may include a first slide portion (532a) that is slidably coupled to the first spiral portion (621a) and has a spiral shape corresponding to the first spiral portion (621a) to provide axial movement of the third portion (533) of the sliding member (530) through rotation of the first plate (621), and a second slide portion (532b) that is slidably coupled to the second spiral portion (622a) and has a spiral shape corresponding to the second spiral portion (622a) to provide axial movement of the third portion (533) through rotation of the second plate (622).

[0121] For example, the spiral parts (621a, 622a) may be parts for axially moving the sliding member (530) in the directions (503, 504) by rotating the housing parts (220, 230) by rotating the hinge plate (610) among the housing (200). For example, the spiral parts (621a, 622a) may be arranged to face each other. For example, the second part (532) of the sliding member (530) may be a part of the sliding member (530) that is coupled to the housing parts (220, 230). For example, the first slide portion (532a) of the second portion (532) may be rotatably coupled to the first spiral portion (621a) so as to be slidable along a spiral path formed by the first spiral portion (621a) of the first plate (621). The second slide portion (532b) of the second portion (532) may be rotatably coupled to the second spiral portion (622a) so as to be slidable along a spiral path formed by the second spiral portion (622a) of the second plate (622).

[0122] For example, while the electronic device (101) changes from a first state (101a) to a second state (101b), the first hinge plate (611) and the first plate (621) coupled with the first hinge plate (611) can be rotated in the rotational direction (601). The second hinge plate (612) and the second plate (622) coupled with the second hinge plate (612) can be rotated in the rotational direction (602) opposite to the rotational direction (601). The first spiral portion (621a) can be rotated in the rotational direction (601) along the first plate (621). The first slide portion (532a) of the sliding member (530) that is slidably engaged with the first spiral portion (621a) can be pressed by rotation of the first spiral portion (621a) in the rotational direction (601), thereby moving the sliding member (530) in the direction (504). The second spiral portion (622a) can be rotated in the rotational direction (602) along the second plate (622). The second slide portion (532b) of the sliding member (530) that is slidably engaged with the second spiral portion (622a) can be pressed by rotation of the second spiral portion (622a) in the rotational direction (602), thereby moving the sliding member (530) in the direction (504). As the sliding member (530) moves in the direction (504), a gap (g) between the second part (532) of the sliding member (530) and the hinge bracket (630) can be formed. However, the embodiment of the present disclosure is not limited thereto.

[0123] For example, while the electronic device (101) changes from the second state (101b) to the first state (101a), the first hinge plate (611) and the first plate (621) coupled with the first hinge plate (611) can be rotated in the rotational direction (602). The second hinge plate (612) and the second plate (622) coupled with the second hinge plate (612) can be rotated in the rotational direction (601) opposite to the rotational direction (602). The first spiral portion (621a) can be rotated in the rotational direction (602) along the first plate (621). The first slide portion (532a) of the sliding member (530) that is slidably engaged with the first spiral portion (621a) can be pushed by the rotation of the first spiral portion (621a) in the rotational direction (601), thereby moving the sliding member (530) in the direction (503). The second spiral portion (622a) can be rotated in the rotational direction (601) along the second plate (622). The second slide portion (532b) of the sliding member (530) that is slidably engaged with the second spiral portion (622a) can be pushed by the rotation of the second spiral portion (622a) in the rotational direction (601), thereby moving the sliding member (530) in the direction (503). However, the embodiments of the present disclosure are not limited thereto. The electronic device (101) may be configured to move a stopper (510) coupled with the sliding member (530) while the state of the electronic device (101) is changed by including a sliding member (530) configured to move along an axis through rotation of the housing parts (220, 230).

[0124] The electronic device (101) may include a plurality of engagement protrusions (640) for guiding states (101a, 101b) of the electronic device (101), and a plurality of elastic members (660) configured to press the plurality of engagement protrusions (640). For example, the first plate (621) of the second housing part (220) may include first engagement protrusions (641). The second plate (622) of the third housing part (230) may include second engagement protrusions (642). The electronic device (101) may include a guide member (650) including a first engagement portion (651) including third engagement protrusions (643) that engage with the first engagement protrusions (641) of the first plate (621), a second engagement portion (652) including fourth engagement protrusions (644) that engage with the second engagement protrusions (642) of the second plate (622), and a connecting portion (653) that extends from the first engagement portion (651) to the second engagement portion (652). For example, the plurality of elastic members (660) may include a first elastic member (661) that provides elastic support to a first engagement portion (651) of the guide member (650) such that the third engagement protrusions (643) engage with the first engagement protrusions (641), and a second elastic member (662) that provides elastic support to a second engagement portion (652) of the guide member (650) such that the fourth engagement protrusions (644) engage with the second engagement protrusions (642).

[0125] For example, the guide member (650) can be engaged with the first plate (621) and the second plate (622) on the second hinge cover (420), respectively. The engaging portions (651, 652) of the guide member (650) can form both ends of the guide member (650). For example, the first engaging protrusions (641) and the third engaging protrusions (643) can be engaged or contacted with each other within the states (101a, 101b) of the electronic device (101), thereby providing a locking force to the housing (200) to maintain the states (101a, 101b) of the electronic device (101). The second interlocking protrusions (642) and the fourth interlocking protrusions (644) can provide a locking force to the housing (200) to maintain the states (101a, 101b) of the electronic device (101) by interlocking or contacting each other within the states (101a, 101b) of the electronic device (101).

[0126] For example, the first elastic member (661) can provide a locking force between the third protrusions (643) (e.g., the third interlocking protrusions) and the first protrusions (641) (e.g., the first interlocking protrusions) by providing a repulsive force in the direction (503) to the first engaging portion (651) of the guide member (650). The second elastic member (662) can provide a locking force between the fourth protrusions (644) (e.g., the fourth interlocking protrusions) and the second protrusions (642) (e.g., the second interlocking protrusions) by providing a repulsive force in the direction (503) to the second engaging portion (652) of the guide member (650). For example, the elastic members (661, 662) may be configured to be movable or deformable in directions (503, 504), respectively, thereby guiding a change in the state of the electronic device (101). However, the embodiments of the present disclosure are not limited thereto.

[0127] The second hinge assembly (260) may include a hinge bracket (630) that accommodates a third portion (533) of a sliding member (530) and includes a guide recess (635) that guides movement of the third portion (533) in a direction (503) corresponding to the longitudinal directions of the third portion (533) and a direction (504) opposite to the direction (503). For example, the hinge bracket (630) may be coupled to the second hinge cover (420). For example, the hinge bracket (630) may be rotatably coupled to the first hinge plate (611) and the second hinge plate (612). For example, the hinge bracket (630) may provide mounting portions for components disposed on the second hinge cover (420). For example, the guide recess (635) may have a length in the directions (503, 504) to guide the sliding of the third part (533) of the sliding member (530) in the directions (503, 504). For example, the guide recess (635) may have a shape corresponding to the shape of the third part (533) to guide the movement of the third part (533) of the sliding member (530). Exemplary structures of the guide recess (635) and / or the hinge bracket (630) to prevent the third part (533) from coming off are described below.

[0128] FIG. 7A illustrates a structure for moving a stopper of an exemplary electronic device. FIG. 7B illustrates a portion of an exemplary electronic device in a first state. FIG. 7C illustrates a portion of an exemplary electronic device in a second state. FIG. 7D illustrates a portion of an exemplary electronic device in a first state. FIG. 7E illustrates a portion of an exemplary electronic device in a second state. FIGS. 7F, 7G, and 7H illustrate a portion of an exemplary electronic device in an exemplary first state.

[0129] Referring to FIGS. 7A, 7B, 7C, 7D, 7E, 7F, 7G, and 7H, the electronic device (101) may include a housing (200) including a first housing part (210), a second housing part (220), and a third housing part (230). The electronic device (101) may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3A) that rotatably couples the first housing part (210) and the second housing part (220). The electronic device (101) may include a second hinge assembly (260) that rotatably couples the second housing part (220) and the third housing part (230). The second housing part (220) and the third housing part (230) may be spaced apart from each other within the first state (101a) of the electronic device (101). The electronic device (101) may include a stopper (510) positioned between the second housing part (220) and the third housing part (230) to support the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101). However, the embodiments of the present disclosure are not limited thereto, and for example, the electronic device (101) illustrated and described in FIGS. 7A to 7H may include structures and / or configurations illustrated and described in FIGS. 2A to 6F. Additionally, in the following, redundant descriptions of structures and / or configurations having the same reference numerals as the structures and / or configurations illustrated and described in FIGS. 2a to 6f may be omitted.

[0130] Referring to Fig. 7a, a stopper (510) that is slidably coupled to a through hole (520) of a second hinge cover (420) is exemplarily illustrated. The direction in which the stopper (510) protrudes from the outer surface (425) of the second hinge cover (420) can be determined or designed by values ​​exemplarily illustrated in Fig. 7a.

[0131] For example, the horizontal distance (s2) that the coupling pin (540) can move along the guide hole (512) can be determined through the following mathematical expression 1 for the movable distance (d) of the sliding member (530) (or the third part (533) of the sliding member (530)) and the movable horizontal distance (p1) of the stopper (510).

[0132]

[0133] For example, the vertical distance (s1) that the coupling pin (540) can move along the guide hole (512) may correspond to the vertical distance (p2) that the stopper (510) can move. In addition, the angle (a) between the moving direction of the stopper (510) and the vertical surface (425a) of the second hinge cover (420) may be determined through the following mathematical expression 2.

[0134]

[0135] Using the above mathematical expressions 1 and 2, the protrusion amount and / or protrusion direction of the stopper (510) in the first state (101a) of the electronic device (101) can be determined or designed. Hereinafter, examples of stoppers (510) that can protrude in various directions are described.

[0136] Referring to FIGS. 7b and 7c, unlike FIG. 7a, the stopper (510) may be movable in a direction corresponding to the vertical surface (425a) of the second hinge cover (420). For example, the stopper (510) may be movably coupled in directions (503, 504) corresponding to the movement direction of the sliding member (530) with respect to the second hinge cover (420). For example, a through hole (520) for protruding the stopper (510) may be formed in a portion of the vertical surface (425a) and a portion of the curved surface (425c) of the outer surface (425) of the second hinge cover (420). In this case, since the direction of movement of the stopper (510) corresponds to the direction of movement of the sliding member (530) (e.g., is the same), the guide hole (512) of the stopper (510) can be omitted.

[0137] Referring to FIGS. 7E and 7F, unlike FIG. 7A, the stopper (510) may be movable in a direction corresponding to the horizontal surface (425b) of the second hinge cover (420). For example, the stopper (510) may be coupled to be movable in directions (701, 702) that are parallel to the direction in which the horizontal surface (425b) faces with respect to the second hinge cover (420). For example, a through hole (520) for protruding the stopper (510) may be formed in a portion of the horizontal surface (425b) and a portion of the curved surface (425c) of the outer surface (425) of the second hinge cover (420). For example, while the electronic device (101) changes from the first state (101a) to the second state (101b), the coupling pin (540) can be moved in the direction (704) along the sliding member (530) moving in the direction (504). By being pulled by the coupling pin (540) moving in the direction (704), the stopper (510) can be moved in the direction (702). For example, while the electronic device (101) changes from the second state (101b) to the first state (101a), the coupling pin (540) can be moved in the direction (703) along the sliding member (530) moving in the direction (503). By being pushed by the coupling pin (540) moving in the direction (703), the stopper (510) can be moved in the direction (701). However, the embodiments of the present disclosure are not limited thereto, and through the mathematical equations exemplarily described in FIG. 7a, the stopper (510) can be protruded in various directions from the second hinge cover (420) to be positioned between the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101), as exemplarily illustrated in FIGS. 7f, 7g, and 7h.

[0138] FIG. 8A illustrates a hinge bracket and a sliding member of an exemplary electronic device. FIGS. 8B, 8C, and 8D are cross-sectional views of the exemplary hinge bracket and the sliding member taken along line A-A' of FIG. 8A. FIG. 8E illustrates the hinge bracket and the sliding member of an exemplary electronic device. FIG. 8F is a cross-sectional view of the exemplary hinge bracket and the sliding member taken along line B-B' of FIG. 8E. FIGS. 8G and 8H illustrate the hinge bracket, the sliding member, and the fastening cover of an exemplary electronic device. FIG. 8I is a cross-sectional view of the exemplary hinge bracket, the sliding member, and the fastening cover taken along line C-C' of FIG.

[0139] Referring to FIGS. 8A, 8B, 8C, 8D, 8E, 8F, 8G, 8H, and 8I, a sliding member (530) and a hinge bracket (630) disposed within the electronic device (101) illustrated and described in FIGS. 6A to 6F are exemplarily illustrated. The sliding member (530) may include a first part (531) coupled with a stopper (510), a second part (532) configured to slide by rotation of a third housing part (e.g., the third housing part (230) of FIG. 2A) relative to a second housing part (e.g., the second housing part (220) of FIG. 2A), and a third part (533) extending from the first part (531) to the second part (532) and providing a driving force to the first part (531) for moving the stopper (510) through the second part (532). The hinge bracket (630) may include a guide recess (635) that accommodates the third part (533) of the sliding member (530) and guides movement of the third part (533) in the longitudinal direction of the third part (533). The second part (532) may include slide parts (532a, 532b) having a spiral shape for converting the rotation of the second housing part (220) and the third housing part (230) with respect to the second hinge cover (e.g., the second hinge cover (420) of FIG. 4a) into the axial movement of the third part (533) by being linked with the second housing part (220) and the third housing part (230), respectively.

[0140] Referring to FIGS. 8A and 8B, the guide recess (635) of the hinge bracket (630) may have a shape corresponding to the third portion (533) of the sliding member (530) so that the third portion (533) can slide within the guide recess (635). For example, in a comparative example, while the third portion (533) slides within the guide recess (635), the third portion (533) may at least partially detach from the guide recess (635). The electronic device (101) may be provided with a structure for preventing the third portion (533) from detaching from the guide recess (635) while the state of the electronic device (101) is changed, as described below.

[0141] Referring to FIGS. 8C and 8D, compared to FIG. 8B, the guide recess (635) and the third portion (533) accommodated in the guide recess (635) may include a structure for expanding the area of ​​contact with each other. For example, referring to FIG. 8C, the guide recess (635) may include protruding portions protruding from the inner surface of the guide recess (635). The third portion (533) may include recess structures that accommodate the protruding portions and have a shape corresponding to the protruding portions. For example, referring to FIG. 8D, the guide recess (635) may have a stepped structure. The third portion (533) accommodated in the guide recess (635) may include stepped portions corresponding to the shape of the guide recess (635) (e.g., a stepped guide recess). However, the embodiment of the present disclosure is not limited thereto, and the guide recess (635) and the third part (533) accommodated in the guide recess (635) may include various structures to increase the contact area with each other, thereby reducing the detachment of the third part (533) from the guide recess (635).

[0142] Referring to FIGS. 8E and 8F, the third portion (533) of the sliding member (530) may include a first shaft portion (533a) and a second shaft portion (533b) spaced apart from the first shaft portion (533a). The guide recess (635) of the hinge bracket (630) may include a first recess (635a) for accommodating the first shaft portion (533a) and a second recess (635b) for accommodating the second shaft portion (533b). The hinge bracket (630) may include a protrusion (810) that separates the first recess (635a) and the second recess (635b) and is disposed between the first shaft portion (533a) and the second shaft portion (533b). For example, the protrusion (810) can separate the first shaft portion (533a) and the second shaft portion (533b). The protrusion (810) can increase the contact area between the third portion (533) and the hinge bracket (630) by coming into contact with the shaft portions (533a, 533b). However, the embodiment of the present disclosure is not limited thereto, and the third portion (533) can include a plurality of shaft portions that are spaced apart from each other. The hinge bracket (630) can include a plurality of recesses corresponding to each of the plurality of shaft portions, and a plurality of protrusions arranged between the plurality of recesses.

[0143] Referring to FIGS. 8g, 8h, and 8i, the second hinge assembly (260) may include a fastening cover (820) coupled to the hinge bracket (630) to prevent the third portion (533) of the sliding member (530) from being separated from the guide recess (635) of the hinge bracket (630). For example, the fastening cover (820) may be disposed on the hinge bracket (630) to at least partially cover the third portion (533). For example, the fastening cover (820) may be fastened to the hinge bracket (630) to restrict movement of the third portion (533) out of the guide recess (635). However, embodiments of the present disclosure are not limited thereto.

[0144] FIG. 9 illustrates a portion of an exemplary electronic device within a first state.

[0145] Referring to FIG. 9, the electronic device (101) may include a housing (e.g., the housing (200) of FIG. 2A) that includes a first housing part (e.g., the first housing part (210) of FIG. 2A), a second housing part (e.g., the second housing part (220) of FIG. 2A), and a third housing part (e.g., the third housing part (230) of FIG. 2A). The electronic device (101) may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3A) that rotatably couples the first housing part (210) and the second housing part (220). The electronic device (101) may include a second hinge assembly (260) that rotatably couples the second housing part (220) and the third housing part (230). The second housing part (220) and the third housing part (230) may be spaced apart from each other within the first state (101a) of the electronic device (101). The electronic device (101) may include a stopper (510) positioned between the second housing part (220) and the third housing part (230) to support the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101). However, the embodiments of the present disclosure are not limited thereto, and for example, the electronic device (101) illustrated and described in FIG. 9 may include structures and / or configurations illustrated and described in FIGS. 2A to 8I. In addition, hereinafter, redundant descriptions of structures and / or configurations having the same reference numerals as the structures and / or configurations illustrated and described in FIGS. 2A to 8I may be omitted.

[0146] Referring to FIG. 9, compared to FIG. 6c, the second part (532) of the sliding member (530) may be positioned closer to the stopper (510) (or one end of the second hinge cover (420)). For example, unlike FIG. 7c, the plates (621, 622) slidably coupled to the second part (532) of the sliding member (530) may be positioned closer to the stopper (510) than the hinge plates (611, 612). By positioning the second part (532) closer to the stopper (510), the length of the third part (533) for connecting the first part (531) coupled to the stopper (510) and the second part (532) may be relatively shorter compared to FIG. 6c. For example, as the length of the third part (533) is shortened, the length of the guide recess (635) of the hinge bracket (630) for accommodating the third part (533) can also be shortened. As the length of the third part (533) is shortened, the electronic device (101) can reduce the third part (533) from being detached from the guide recess (635) while the state of the electronic device (101) is changed.

[0147] FIG. 10A illustrates a portion of an exemplary electronic device in a first state. FIG. 10B illustrates a portion of an exemplary electronic device in a second state. FIG. 10C illustrates a portion of an exemplary electronic device in a first state. FIG. 10D illustrates a portion of an exemplary electronic device in a second state.

[0148] Referring to FIGS. 10A, 10B, 10C, and 10D, the electronic device (101) may include a housing (200) including a first housing part (210), a second housing part (220), and a third housing part (230). The electronic device (101) may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3A) that rotatably couples the first housing part (210) and the second housing part (220). The electronic device (101) may include a second hinge assembly (e.g., the second hinge assembly (260) of FIG. 3A) that rotatably couples the second housing part (220) and the third housing part (230). The second housing part (220) and the third housing part (230) may be spaced apart from each other within the first state (101a) of the electronic device (101). The electronic device (101) may include a stopper (510) positioned between the second housing part (220) and the third housing part (230) to support the second housing part (220) and the third housing part (230) within the first state (101a) of the electronic device (101).

[0149] Unlike the stopper (510) illustrated and described in FIGS. 5A to 9, referring to FIGS. 10A to 10D, the stopper (510) may be provided as a part of the second hinge cover (420) or may have a fixed position relative to the second hinge cover (420). For example, the stopper (510) may be a structure protruding from the outer surface (425) of the second hinge cover (420). The position of the stopper (510) may be fixed regardless of a change in the state of the electronic device (101). For example, referring to FIGS. 5A and 5B, the stopper (510) may be a structure having a shape protruding from one end of the second hinge cover (420). For example, referring to FIGS. 5c and 5d, the stopper (510) may be a structure formed across a horizontal surface (e.g., horizontal surface (425b) of FIG. 5a) of the second hinge cover (420) to increase the contact area with the housing parts (220, 230). However, the embodiments of the present disclosure are not limited thereto.

[0150] For example, the electronic device (101) may include a protective member (1010) disposed on a longitudinal end of the second hinge cover (420) to protect the fifth display portion (245) of the flexible display (240). The stopper (510) may be formed integrally with the protective member (1010) or disposed adjacent to the protective member (1010). However, the embodiments of the present disclosure are not limited thereto.

[0151] The technical problems to be achieved in the embodiments of the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary knowledge in the technical field to which the present disclosure pertains.

[0152] As described above, a multi-foldable electronic device (e.g., electronic device (101) of FIG. 1) may include a housing (e.g., housing (200) of FIG. 2A) including a first housing part (e.g., first housing part (210)), a second housing part (e.g., second housing part (220)), and a third housing part (e.g., third housing part (230) of FIG. 2A). The multi-foldable electronic device may include a first hinge assembly (e.g., the first hinge assembly (250) of FIG. 3a) that rotatably couples the first housing part and the second housing part, and a second hinge assembly (e.g., the second hinge assembly (260) of FIG. 3a) that rotatably couples the second housing part and the third housing part, and includes a first sink arm (e.g., the first slide portion (532a) of FIG. 6c) and a second sink arm (e.g., the second slide portion (532b) of FIG. 6c) and a sliding member (e.g., the sliding member (530) of FIG. 5a) that slides according to the linkage between the spiral surfaces of the first sink arm and the second sink arm and the rotation of the third housing part with respect to the second housing part. The multi-foldable electronic device may include a stopper (e.g., a stopper (510) of FIG. 5A) coupled to the sliding member so as to be movable according to the rotation of the third housing part with respect to the second housing part. The stopper may be configured so that the second housing part and the third housing part may be spaced apart from each other in an unfolded state of the multi-foldable electronic device (e.g., a first state (101a) of FIG. 2A). The stopper may be configured to be positioned between the second housing part and the third housing part so as to support the second housing part and the third housing part in an unfolded state of the multi-foldable electronic device (e.g., a first state (101a) of FIG. 2A).

[0153] For example, the multi-foldable electronic device may further include a first hinge cover (e.g., the first hinge cover (410) of FIG. 4A) covering a portion of the first hinge assembly, and a second hinge cover (e.g., the second hinge cover (420) of FIG. 4A) wider than the first hinge cover and covering a portion of the second hinge assembly. The first housing part and the second housing part may be configured such that the first hinge cover comes into contact with each other before the first hinge cover comes into contact with the first housing part and the second housing part. The second housing part and the third housing part may be configured such that the second hinge cover comes into contact with the stopper before the second housing part and the third housing part come into contact with the second housing part and the third housing part.

[0154] For example, the second hinge cover may include a through hole (e.g., the through hole (520) of FIG. 5A) for accommodating the stopper. The stopper may be configured to protrude from an outer surface of the second hinge cover (e.g., the outer surface (425) of FIG. 5A) through the through hole so as to come into contact with the second housing part and the third housing part within the unfolded state of the multi-foldable electronic device. The stopper may be configured to be disposed within the through hole so as to form a continuous surface together with the outer surface of the second hinge cover within the multi-folded state of the multi-foldable electronic device (e.g., the second state (101b) of FIG. 2B).

[0155] For example, the second hinge cover may further include a guide rail (e.g., a guide rail (521) of FIG. 5A) protruding from the inner surface of the through hole to guide the position of the stopper. The stopper may include a guide groove (e.g., a guide groove (511) of FIG. 5A) slidably coupled to the guide rail so that the stopper moves in a first direction relative to the second hinge cover and a second direction (e.g., a direction (502) of FIG. 5A) opposite to the first direction (e.g., a direction (501) of FIG. 5A).

[0156] For example, the sliding member may include a first portion (e.g., the first portion (531) of FIG. 5d) coupled with the stopper, a second portion (e.g., the second portion (532) of FIG. 6c) defining the first sink arm and the second sink arm to be raised or lowered by rotation of the third housing part relative to the second housing part, and a third portion (e.g., the third portion (533) of FIG. 5d) extending from the first portion to the second portion and providing a driving force to the first portion for moving the stopper through the second portion.

[0157] For example, the stopper may include a guide hole (e.g., guide hole (512) of FIG. 5d). The first part may include a coupling hole (e.g., coupling hole (531a) of FIG. 5d). The multi-foldable electronic device may further include a coupling pin (e.g., coupling pin (540) of FIG. 5a) penetrating the guide hole and the coupling hole so that the first part is slidably coupled to the stopper.

[0158] For example, the second hinge assembly may include a hinge bracket that accommodates the third portion of the sliding member and includes a guide recess that guides movement of the third portion in a third direction corresponding to the longitudinal directions of the third portion (e.g., direction (503) of FIG. 5A) and a fourth direction opposite to the third direction (e.g., direction (504) of FIG. 5A).

[0159] For example, the second hinge assembly may further include a fastening cover (e.g., fastening cover (820) of FIG. 8g) coupled to the hinge bracket to prevent the third portion from being separated from the guide recess.

[0160] For example, the third portion may include a first shaft portion (e.g., the first shaft portion (533a) of FIG. 8e) and a second shaft portion (e.g., the second shaft portion (533b) of FIG. 8e) spaced apart from the first shaft portion. The guide recess may include a first recess (e.g., the first recess (635a) of FIG. 8f) for accommodating the first shaft portion, and a second recess (e.g., the second recess (635b) of FIG. 8f) for accommodating the second shaft portion. The hinge bracket may further include a protrusion (e.g., the protrusion (810) of FIG. 8e) that separates the first recess and the second recess and is disposed between the first shaft portion and the second shaft portion.

[0161] For example, the second hinge assembly may include a first hinge plate (e.g., the first hinge plate (611) of FIG. 6C) coupled to the second housing part, and a second hinge plate (e.g., the second hinge plate (612) of FIG. 6C) coupled to the third housing part. The second housing part may include a first plate (e.g., the first plate (621) of FIG. 6C) coupled to the first hinge plate so as to rotate together with the first hinge plate, and including a first spiral portion (e.g., the first spiral portion (621a) of FIG. 6C). The third housing part may include a second plate (e.g., the second plate (622) of FIG. 6c) that is coupled to the second hinge plate so as to rotate together with the second hinge plate and includes a second spiral portion (e.g., the second spiral portion (622a) of FIG. 6c). The first sink arm may be slidably coupled to the first spiral portion and may have a spiral shape corresponding to the first spiral portion to provide axial movement of the third part through rotation of the first plate. The second sink arm may be slidably coupled to the second spiral portion and may have a spiral shape corresponding to the second spiral portion to provide axial movement of the third part through rotation of the second plate.

[0162] For example, the multi-foldable electronic device may further include a first hinge cover covering a portion of the first hinge assembly and being covered by the first housing part and the second housing part that contact each other in the unfolded state of the multi-foldable electronic device, and a second hinge cover wider than the first hinge cover and covering a portion of the second hinge assembly, the second hinge cover defining a vertical plane (e.g., a vertical plane 425a in FIG. 5A), a horizontal plane perpendicular to the vertical plane (e.g., a horizontal plane 425b in FIG. 5A), and a curved plane extending from the vertical plane to the horizontal plane (e.g., a curved plane 425c in FIG. 5A). The second hinge cover may expose a portion of the stopper to the outside of the multi-foldable electronic device, and may include a through hole formed in a portion of the vertical plane, a portion of the horizontal plane, and a portion of the curved plane.

[0163] For example, the stopper may be in contact with a side surface of the second housing part (e.g., side surface (220a) of FIG. 5A) and a side surface of the third housing part facing the side surface of the second housing part (e.g., side surface (230a) of FIG. 5A) in the unfolded state of the multi-foldable electronic device.

[0164] For example, the second hinge assembly may include a first hinge plate coupled to the second housing part, and a second hinge plate coupled to the third housing part. The second housing part may include a first plate coupled to the first hinge plate to rotate together with the first hinge plate and including first engaging protrusions (e.g., first engaging protrusions (641) of FIG. 6C). The third housing part may include a second plate coupled to the second hinge plate to rotate together with the second hinge plate and including second engaging protrusions (e.g., second engaging protrusions (642) of FIG. 6C). The multi-foldable electronic device may further include a guide member (e.g., a guide member (650) of FIG. 6C). The guide member may include a first engagement portion (e.g., a first engagement portion (651) of FIG. 6c) including third engagement protrusions (e.g., third engagement protrusions (643) of FIG. 6c) that engage with the first engagement protrusions of the first plate, a second engagement portion (e.g., a second engagement portion (652) of FIG. 6c) that includes fourth engagement protrusions (e.g., fourth engagement protrusions (644) of FIG. 6c) that engage with the second engagement protrusions of the second plate, and a connecting portion (e.g., a connecting portion (653) of FIG. 6c) that extends from the first engagement portion to the second engagement portion.

[0165] For example, the multi-foldable electronic device may further include a first elastic member (e.g., the first elastic member (661) of FIG. 6c) that provides elastic support to the first interlocking portion so that the third interlocking protrusions are engaged with the first interlocking protrusions, and a second elastic member (e.g., the second elastic member (662) of FIG. 6c) that provides elastic support to the second interlocking portion so that the fourth interlocking protrusions are engaged with the second interlocking protrusions.

[0166] For example, the multi-foldable electronic device may further include a flexible display (e.g., the flexible display (240) of FIG. 2A) coupled to the housing. The flexible display may include a first foldable portion (e.g., the fourth display portion (244) of FIG. 2A) configured to be bent by the first hinge assembly within the multi-folded state of the multi-foldable electronic device, and a second foldable portion (e.g., the fifth display portion (245) of FIG. 2A) wider than the first foldable portion and configured to be bent by the second hinge assembly within the multi-folded state of the multi-foldable electronic device.

[0167] According to the above, the foldable electronic device may include a housing including a first housing part (e.g., the second housing part (220) of FIG. 2A) and a second housing part (e.g., the third housing part (230) of FIG. 2A), and a hinge assembly (e.g., the second hinge assembly (260) of FIG. 3A) that rotatably couples the first housing part and the second housing part. The first housing part and the second housing part may be spaced apart from each other in an unfolded state of the foldable electronic device.
