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, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, 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, 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).

[0036] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)).

[0058] For example, the fastening member (250, 260) may extend from the frame (330). For example, the fastening member (250, 260) may surround a part of the user's body (e.g., a wrist) when the electronic device (101) is worn by the user. For example, the fastening member (250, 260) may be configured to fasten the electronic device (101) onto a part of the user's body. The fastening member (250, 260) may support the electronic device (101) using a part of the user's body. For example, the fastening member (250, 260) may be a part of the strap (320) that is spaced apart from the core (310) when the core (310) is fastened to the strap (320).

[0059] According to one embodiment, the core (310) may include a first surface (310a) (e.g., front surface (210A) of FIG. 2a), a second surface (310b) opposite the first surface (310a) (e.g., back surface (310B) of FIG. 2b), and a third surface (310c) between the first surface (310a) and the second surface (310b).

[0060] For example, the first side (310a) may be configured to display visual information to a user of the electronic device (101). For example, the first side (310a) may be formed by a display (e.g., the display (201) of FIG. 2A) for displaying visual information to the user. For example, the second side (310b) may be a side that comes into contact with a part of the body of the user when the electronic device (101) is worn by the user. For example, the third side (310c) may be a side that comes into contact with the strap (320) of the electronic device (101) when the core (310) is fastened to the strap (320). For example, the core (310) may include a structure for fastening to the strap (320) on the third side (310c) so as to be detachably coupled to the strap (320). With regard to the above structure for fastening with the above strap (320), it is described below in FIG. 4a.

[0061] In one embodiment, the core (310) may further include a first housing (311), and a second housing (312) coupled with the first housing (311) to rotate with respect to the first housing (311). For example, the first housing (311) may include a first face (310a) and a third face (310c) of the core (310). The third face (310c) may rotate with respect to the first face (310a) and the second face (310b). For example, the second housing (312) may rotate with respect to the first housing (311) while the core (310) is fastened to the strap (320). The second housing (312) may be configured to rotate so that the core (310) is detachable from the strap (320).

[0062] According to one embodiment, the core (310) may further include a sensor module (211) (e.g., the sensor module (176) of FIG. 1) configured to obtain biometric information of a user from a part of the body of the user wearing the electronic device (101). For example, at least a portion of the sensor module (211) may be exposed through the second surface (310b) of the core (310). For example, the sensor module (211) may detect an external environmental condition (e.g., a physical condition of the user) and generate an electrical signal or a data value corresponding to the detected condition. The electronic device (101) may be configured to display information related to the body of the user to the user based on the electrical signal or the data value detected by the sensor module (211). For example, the sensor module (211) may include, but is not limited to, a biometric sensor.

[0063] According to one embodiment, the frame (330) may include a fourth face (330a) facing at least a portion of the core (310) fastened to the strap (320), and a fifth face (330b) opposite the fourth face (330a). For example, the fourth face (330a) may be a face that comes into contact with the core (310) when the core (310) is fastened to the strap (320). For example, the fourth face (330a) may be a face that faces the third face (310c) of the core (310) while the core (310) is fastened to the strap (320). For example, the fourth face (330a) may include a structure for fastening to the core (310). For example, the fifth face (330b) may be a face that comes into contact with the fastening member (250, 260). For example, the fifth side (330b) may be a side spaced apart from the core (310) when the core (310) is fastened to the strap (320). With regard to the fourth side (330a) including a structure for fastening to the core (310), this will be described below in FIG. 4a.

[0064] According to one embodiment, the fastening member (250, 260) of the strap (320) may extend from the fifth side (330b) of the frame (330). The strap (320) may include a support member (340) disposed within the frame (330), and a protective member (350) surrounding the support member (340) and forming at least a portion of the fastening member (250, 260). For example, the fastening member (250, 260) may be connected to the fifth side (330b). For example, the fastening member (250, 260) may be formed integrally with the frame (330).

[0065] For example, the support member (340) can be disposed between the fourth side (330a) of the frame (330) and the fifth side (330b) opposite to the fourth side (330a). For example, the support member (340) can support the frame (330). For example, since the support member (340) has rigidity, it can support the core (310) that is fastened to the frame (330). For example, the support member (340) can include at least one of aluminum, plastic, and metal, but is not limited thereto. For example, the protection member (350) can surround the support member (340). For example, the protection member (350) can be deformable. For example, the protective member (350) may be configured to deform so that the fastening member (250, 260) is fastened to the user's body by forming at least a portion of the fastening member (250, 260). For example, the protective member (350) may include, but is not limited to, rubber.

[0066] According to one embodiment, the rigidity of the frame (330) may be higher than the rigidity of the fastening member (250, 260). The thickness (d) of the frame (330) may be positioned within a range of 0.1 mm or more and 0.3 mm or less. For example, since the frame (330) includes a support member (340) having rigidity, the rigidity of the frame (330) may be higher than the rigidity of the fastening member (250, 260). By positioning the thickness (d) of the frame (330) within a range of 0.1 mm or more and 0.3 mm or less, the electronic device (101) may reduce the weight of the frame (330) to be fastened to the core (310).

[0067] According to one embodiment, the core (310) can be removably coupled to the frame (330) of the strap (320). For example, the core (310) can be fastened to the frame (330) by moving in a first direction (301) while being spaced from the strap (320). For example, the core (310) can be fastened to the frame (330) by moving in a second direction (302) opposite to the first direction (301) while being fastened to the strap (320). The electronic device (101) can provide a structure for the core (310) to be removably coupled to the frame (330) to the user by utilizing the rotation of the second housing (312) with respect to the first housing (311) of the core (310) and the movement of the core (310) with respect to the frame (330). The electronic device (101) may be required to provide various user experiences to the user by providing the structure for detachably coupling the core (310) to the frame (330).

[0068] In another embodiment described above, the electronic device (101) may provide various user experiences to a user of the electronic device (101) by including a core (310) and a strap (320) detachably coupled to the core (310). The strap (320) may include a frame (330) for supporting the core (310) and a fastening member (250, 260) in contact with the frame (330), such that the strap (320) to which the core (310) is fastened may be configured to be fastened to a part of the user's body.

[0069] Figure 4a is an exploded perspective view of the core of an exemplary electronic device. Figure 4b illustrates an exemplary electronic device.

[0070] Referring to FIGS. 4A and 4B, the electronic device (101) may include a core (310) and a strap (320). The strap (320) may include a frame (330) detachably coupled to the core (310), and a fastening member (250, 260) that comes into contact with the frame (330) and wraps around a part of a user's body when the electronic device (101) is worn by the user.

[0071] According to one embodiment, the first housing (311) may include a front plate (201) and a cover plate (450). The second housing (312) may include a rear plate (207) and a wheel (460). For example, the front plate (201) may include a display module (e.g., the display module (160) of FIG. 1). For example, the cover plate (450) may surround electronic components within the electronic device (101). For example, the cover plate (450) may be coupled to the front plate (201). For example, the rear plate (207) may include a sensor module (e.g., the sensor module (176) of FIG. 1, the sensor module (211) of FIG. 2B). For example, the wheel (460) may be coupled to the rear plate (207). For example, the wheel (460) can be coupled to the cover plate (450) so as to be rotatable in a first rotational direction (401) with respect to the cover plate (450) and a second rotational direction (402) opposite to the first rotational direction (401). By coupling the wheel (460) so as to be rotatable with respect to the cover plate (450), the second housing (312) can be coupled to the first housing (311) so as to be rotatable in a first rotational direction (401) with respect to the first housing (311) and a second rotational direction (402) opposite to the first rotational direction.

[0072] According to one embodiment, the core (310) may include a first fastening portion (410) and a second fastening portion (420) movable with respect to the first fastening portion (410). For example, the first fastening portion (410) may be included in a first housing (311). The second fastening portion (420) may be included in a second housing (312) rotatable with respect to the first housing (311). For example, the core (310) may include a first housing (311) defining a first fastening portion (410), and a second housing (312) defining a second fastening portion (420) and coupled with the first housing (311) to rotate in a first rotational direction (401) and a second rotational direction (402) opposite the first rotational direction (401) with respect to the first housing (311). For example, the second fastening portion (420) may be movable relative to the first fastening portion (410) by moving along the second housing (312) rotating relative to the first housing (311). For example, the second fastening portion (420) may be configured to move toward the first fastening portion (410) with respect to the first fastening portion (410) or to move in a direction opposite to the direction toward the first fastening portion (410). For example, the first fastening portion (410) and the second fastening portion (420) may protrude from the third surface (310c) of the core (310). For example, the first fastening portion (410) and the second fastening portion (420) may face the fourth surface (e.g., the fourth surface (330a) of FIG. 3) of the strap (320) when the core (310) is fastened to the frame (330) of the strap (320).

[0073] According to one embodiment, the frame (330) of the strap (320) may include a first guide groove (430) for receiving a first fastening portion (410). The frame (330) may include a second guide groove (440) including a first portion (441) for passing a second fastening portion (420), and a second portion (442) extending from the first portion (441) and guiding movement of the second fastening portion (420) passing through the first portion (441) relative to the first fastening portion (410).

[0074] For example, the first guide groove (430) can be connected to the first fastening portion (410). For example, the first guide groove (430) can have a shape corresponding to the shape of the first fastening portion (410). For example, the first guide groove (430) can be configured to accommodate the first fastening portion (410), thereby allowing the first fastening portion (410) to slide within the first guide groove (430). For example, the first guide groove (430) may be configured to accommodate the first fastening portion (410) moving along the core (310) moving in a first direction (301) and a second direction (302) opposite to the first direction (301) with respect to the frame (330), so that the first fastening portion (410) can move in the first direction (301) and the second direction (302) within the first guide groove (430). For example, the first guide groove (430) may guide the movement of the first fastening portion (410) while the core (310) is fastened to the strap (320). For example, the first guide groove (430) may guide the position and / or direction in which the core (310) is fastened to the frame (330) by guiding the position at which the first fastening portion (410) is fastened.

[0075] For example, the second guide groove (440) can guide the movement of the second fastening portion (420) while the core (310) is fastened to the strap (320). For example, the second guide groove (430) can guide the position and / or direction in which the core (310) is fastened to the frame (330) by guiding the position in which the second fastening portion (420) is fastened. For example, the second guide groove (440) can be configured to fasten the core (310) to the strap (320) by fastening the second fastening portion (420) to the frame (330) while the core (310) is fastened to the strap (320).

[0076] For example, the first part (441) of the second guide groove (440) may have a shape corresponding to the second fastening part (420) in order to pass the second fastening part (420). For example, the width of the first part (441) may be greater than or substantially equal to the width of the second fastening part (420). For example, the first part (441) may guide the movement of the second fastening part (420) with respect to the first fastening part (410) while the core (310) is fastened to the frame (330). For example, the first part (441) may be configured to guide the movement of the second fastening part (420) with respect to the first fastening part (410), thereby allowing the second housing (312) including the second fastening part (420) to rotate with respect to the first housing (311) including the first fastening part (410).

[0077] For example, the second part (442) of the second guide groove (440) can be fastened to the second fastening portion (420). For example, the second part (442) of the second guide groove (440) can be configured to guide the movement of the second fastening portion (420) that has passed through the first part (441) with respect to the first fastening portion (410), thereby allowing the second fastening portion (420) to slide within the second part (442). For example, the second guide groove (440) may be configured to accommodate a second fastening portion (420) that moves along the second housing (312) in a first rotational direction (401) relative to the first housing (311) and a second rotational direction (402) opposite to the first rotational direction (401), so that the second fastening portion (420) can move relative to the first fastening portion (410) formed in the first housing (311) within the second portion (442).

[0078] According to one embodiment, the second fastening portion (420) may be configured to be slidable relative to the first fastening portion (410) in a first rotational direction (401) and a second rotational direction (402) opposite to the first rotational direction (401), thereby providing a disengaged state in which the core (310) is movable relative to the strap (320) within an assembled state of the electronic device (101) in which at least a portion of the first fastening portion (410) is positioned within the first guide groove (430), and a fastened state in which the core (310) is fastened to the strap (320).

[0079] The disassembled state of the electronic device (101) may be a state in which the core (310) and the strap (320) are separated. For example, the disassembled state may be a state in which the core (310) is detached from the frame (330) of the strap (320). For example, the disassembled state may be a state in which the first fastening portion (410) is positioned outside the first guide groove (430). For example, the disassembled state may be a state in which the second fastening portion (420) is positioned outside the second guide groove (440).

[0080] The assembled state of the electronic device (101) may be a state in which at least a portion of the first fastening portion (410) of the core (310) is positioned within the first guide groove (430) of the frame (330). The assembled state may include a plurality of states, including an unfastened state in which the core (310) is movable with respect to the strap (320) and a fastened state in which the core (310) is fastened to the strap (320). For example, the assembled state may be a state in which at least a portion of the core (310) is in contact with the frame (330). For example, the assembled state may be a state in which at least a portion of the third surface (310c) of the core (310) faces the fourth surface (e.g., the fourth surface (330a) of FIG. 3) of the frame (330). For example, the assembled state may be a state in which at least a portion of the second fastening portion (420) is positioned within the second guide groove (44).

[0081] The unfastened state of the electronic device (101) may be a state in which the core (310) is movable with respect to the frame (330) of the strap (320). For example, the unfastened state may be a state in which the core (310) is movable with respect to the frame (330) in a first direction (301) and a second direction (302) opposite to the first direction (301). For example, the unfastened state may be a state in which the first fastening portion (410) is movable within the first guide groove (430) in a first direction (301) and a second direction (302) opposite to the first direction (301). For example, the released state may include a state in which the second fastening portion (420) is movable from the first part (441) to the second part (442) and a state in which the second fastening portion (420) is movable from the second part (442) to the first part (441).

[0082] The fastened state of the electronic device (101) may be a state in which the core (310) cannot move with respect to the strap (320). For example, the fastened state may be a state in which the first fastening portion (410) cannot move within the first guide groove (430). For example, the fastened state may be a state in which the second fastening portion (420) is fastened with the second portion (442) of the second guide groove (440).

[0083] For example, a second housing (312) including a second fastening portion (420) may be rotatable in a first rotational direction (401) and a second rotational direction (402) opposite to the first rotational direction (401) with respect to a first housing (311) including a first fastening portion (410). The second fastening portion (420) may be slidable in the first rotational direction (401) and the second rotational direction (402) with respect to the first fastening portion (410) by rotating along the second housing (312) rotating with respect to the first housing (311).

[0084] For example, in the assembled state of the electronic device (101), the first fastening portion (410) may be positioned within the first guide groove (430). The second fastening portion (420) may be positioned within the second portion (442) of the second guide groove (440). The second fastening portion (420) may be configured to slide in a first rotational direction (401) and a second rotational direction (402) opposite to the first rotational direction (401) with respect to the first fastening portion (410) fixed by the first guide groove (430) within the second guide groove (440), thereby providing a fastened state and a disengaged state of the electronic device (101).

[0085] According to one embodiment, the first portion (441) can move the second fastening portion (420) in the first rotational direction (401) relative to the first fastening portion (410) by pressing the second fastening portion (420) while the electronic device (101) is changed from an unassembled state in which the core (310) is separated from the strap (320) to an assembled state in which at least a portion of the first fastening portion (410) is positioned within the first guide groove (430). The second portion (442) may include a first region (442a) configured to provide a disengaged state in which the core (310) is movable relative to the strap (320) by receiving a second fastening portion (420) connected to the first portion (441) and passing through the first portion (441), and a second region (442b) configured to provide a fastened state in which the core (310) is fastened to the strap (320) by receiving at least a portion of the second fastening portion (420) extending from the first region (442a) and moving in a second rotational direction (402) opposite to the first rotational direction (401) relative to the first fastening portion (410).

[0086] For example, while the electronic device (101) is changing from an unassembled state to an assembled state, the core (310) can move in a first direction (301) with respect to the frame (330). At least a portion of the first fastening portion (410) can be positioned within a first guide groove (430). Along the core (310) moving in the first direction (301), the second fastening portion (420) can move in the first direction (301) with respect to the frame (330). Since the at least a portion of the first fastening portion (410) is positioned within the first guide groove (430), the second fastening portion (420) can be pressed by the first portion (441) for passing the second fastening portion (420) as it moves in the first direction (301) with respect to the frame (330). By the pressure of the first part (441), the second fastening part (420) can be moved in the first rotational direction (401) as it moves in the first direction (301) with respect to the frame (330).

[0087] For example, the first region (442a) of the second portion (442) may be a region that comes into contact with the first portion (441). For example, the first region (442a) may be a region for the second fastening portion (420) to move from the second portion (442) to the first portion (441). For example, the width of the first region (441a) may be substantially the same as the width of the first portion (441). For example, the first region (441a) may be configured to provide a space for the second fastening portion (420), thereby allowing the second fastening portion (420) to move in the first direction (301) and in the second direction (302) opposite to the first direction (301).

[0088] For example, the second region (442b) of the second part (442) may be a region spaced apart from the first part (441). For example, the second region (442b) may be a region for fastening the second fastening part (420) to the frame (330). For example, the second region (442b) may be a region where the second fastening part (420), which was moved in the first rotational direction (401) with respect to the first fastening part (410) by the pressure of the first part (441) while the electronic device (101) is changing from a released state to a fastened state, moves in the second rotational direction (402) opposite to the first rotational direction (401) after passing through the first part (441). For example, the second fastening portion (420) may be positioned within the first region (442a) after passing through the first portion (441) as it moves in the first direction (301) with respect to the frame (330) within the unlocked state. The second fastening portion (420) positioned within the first region (442a) may be configured to cause the electronic device to change from the unlocked state to the locked state by moving from the first region (442a) to the second region (442b).

[0089] According to one embodiment, the first portion (441) may further include a guide structure (441a) for guiding movement of the second fastening portion (420) relative to the first fastening portion (410) by pressing the second fastening portion (420) relative to the frame (330) as the core (310) moves relative to the strap (320). For example, the guide structure (441a) may have an inclined surface for guiding movement of the second fastening portion (420). For example, the second fastening portion (420) may move along the guide structure (441a) relative to the first fastening portion (410) in a first rotational direction (401) and a second rotational direction (402) opposite to the first rotational direction (401) by moving along the core (310) moving relative to the frame (330).

[0090] According to one embodiment, the core (310) may further include a guide hole (451) that is penetrated by the second fastening portion (420) and guides movement of the second fastening portion (420) with respect to the first fastening portion (410). For example, the guide hole (451) may be formed in the first housing (311). The second fastening portion (420) may guide rotation of the second housing (312) with respect to the first housing (311) by passing through the guide hole (451). For example, the guide hole (451) may be in contact with the first fastening portion (410). The guide hole (451) may extend from the first fastening portion (410). The second fastening portion (420) can be guided to move in a first rotational direction (401) and a second rotational direction opposite to the first rotational direction (401) with respect to the first fastening portion (410) through the guide hole (451).

[0091] According to one embodiment, the core (310) may further include a first magnet (461) movable relative to the first fastening portion (410) along the second fastening portion (420), and a second magnet (462) configured to interact with the first magnet (461) to move the second fastening portion (420) relative to the first fastening portion (410) in a first rotational direction (401) and a second rotational direction (402) opposite to the first rotational direction (401).

[0092] For example, the first magnet (461) may be placed inside the second housing (312). The second magnet (462) may be placed inside the first housing (311). The first magnet (461) and the second magnet (462) may have different magnetic poles. The first magnet (461) and the second magnet (461) may be configured to move the second housing (312) in a second rotational direction (402) opposite to the first rotational direction (401) with respect to the first housing (311) by contacting each other through a magnetic force. The first magnet (461) and the second magnet (462) may be configured to be spaced apart from each other so as to move the second housing (312) in the first rotational direction (401) with respect to the first housing (311). The first magnet (461) and the second magnet (462) may be configured to move the second housing (312) with respect to the first housing (311), thereby moving the second fastening portion (420) with respect to the first fastening portion (410). However, the present invention is not limited thereto. The electronic device (101) may include a plurality of magnets configured to move the second fastening portion (420) with respect to the first fastening portion (410) by magnetic force.

[0093] According to one embodiment, the first guide groove (430) may be in contact with the second guide groove (440). The frame (330) may further include a step (435) between the first guide groove (430) and the second guide groove (440). For example, the second guide groove (440) may extend from the first guide groove (430). For example, the first guide groove (430) may be in contact with a first region (442a) among the first portion (441) and the second portion (442). For example, the depth of the first guide groove (430) may be greater than the depth of the second guide groove (440). Since the depth of the first guide groove (430) is greater than the depth of the second guide groove (440), a step (435) may be formed within the frame (330). For example, the step (435) can compartmentalize the first guide groove (430) and the second guide groove (440). By including the step (435), the frame (330) can reduce the second fastening portion (420) from being dislodged from the second guide groove (440) to the first guide groove (430) that is in contact with the second guide groove (440).

[0094] According to one embodiment, the frame (330) may include a fourth surface (330a) facing at least a portion of the core (310) fastened to the strap (320), and a fifth surface (330b) opposite the fourth surface (330a). The fourth surface (330a) may face at least a portion of the core (310) in an assembled state of the electronic device (101) in which at least a portion of the first fastening portion (410) is positioned within a first guide groove (430). The fourth surface (330a) may be formed with the first guide groove (430) and the second guide groove (440). The second fastening portion (420) may contact the first fastening portion (410) in a disengaged state within the assembled state in which the core (310) is movable with respect to the strap (320). The second fastening portion (420) can be separated from the first fastening portion (410) within the fastening state within the assembled state in which the core (310) is fastened to the strap (320).

[0095] For example, while the electronic device (101) is in the disassembled state, the second fastening portion (420) can be separated from the first fastening portion (410) by the first magnet (461) and the second magnet (462), which are in contact with each other by magnetic force. While the electronic device (101) changes from the disassembled state to the assembled state, the second fastening portion (420) can be moved toward the first fastening portion (410) by being pressed by the first part (441) (or guide structure (441a)) of the second guide groove (440). The second fastening portion (420) can come into contact with the first fastening portion (410) while passing through the first part (441). After the second fastening portion (420) passes through the first portion (441), the second fastening portion (420) can be separated from the first fastening portion (410) within the second portion (442) of the second guide groove (440) by the magnetic force between the first magnet (461) and the second magnet (462). The second guide groove (440) can change the electronic device (101) from a released state to a fastened state by being separated from the first fastening portion (410) within the second portion (442).

[0096] According to one embodiment, the length (l1) of the first fastening portion (410) protruding from the third face (310c) of the core (310) facing the fourth face (330a) in the assembled state of the electronic device (101) may be greater than the length (l2) of the second fastening portion (420) protruding from the third face (310c). For example, the first fastening portion (410) may extend from the third face (310c) of the core (310). The second fastening portion (420) may protrude from the third face (310c) through a guide hole (451) formed on the third face (310c). The length (l1) of the first fastening portion (410) protruding from the third surface (310c) may be greater than the length (l2) of the second fastening portion (420) protruding from the third surface (310c) through the guide hole (451). The depth of the first guide groove (430) in contact with the second guide groove (440) may be greater than the depth of the second guide groove (440) that accommodates the second fastening portion (420) in order to accommodate the first fastening portion (410). Since the length (l1) is greater than the length (l2), the first fastening portion (410) can guide the position at which the core (310) is fastened to the frame (330) together with the first guide groove (430).

[0097] According to the above-described embodiment, the electronic device (101) may be configured such that the core (310) is detachably coupled to the frame (330) of the strap (320) by including a first fastening portion (410) and a second fastening portion (420) movable with respect to the first fastening portion (410). The frame (330) may include a first guide groove (430) configured to receive the first fastening portion (410) and a second guide groove (440) guiding movement of the second fastening portion (420), thereby providing a variety of user experiences to a user of the electronic device (101).

At least a portion of the first fastening portion (410) can be positioned within the first guide groove (430). Since the at least a portion of the first fastening portion (410) is positioned within the first guide groove (430), the second fastening portion (420) can move in a first rotational direction (401) toward the first fastening portion (410) by being pressed by the first portion (441) of the second guide groove (440). By the first portion (441), the first magnet (461) and the second magnet (462) can be spaced apart from each other. At least a part of the second fastening portion (420) may be positioned within the first portion (441). By positioning at least a part of the first fastening portion (410) within the first guide groove (430) and at least a part of the second fastening portion (420) within the first portion (441), the electronic device (101) may change from the disassembled state to the disassembled state within the assembled state.

[0102] Referring to FIGS. 5b and 5c, while the electronic device (101) changes from an unfastened state to a fastened state, the core (310) can move in a first direction (301) with respect to the frame (330). The first fastening portion (410) can be located within the first guide groove (430). The second fastening portion (420) can pass through the first portion (441). After passing through the first portion (441), the second fastening portion (420) can move in a second rotational direction (402) from the first region (442a) of the second portion (442) toward the second region (442b) by the magnetic force of the first magnet (461) and the second magnet (462). By positioning at least a portion of the second fastening portion (420) within the second region (442b), the electronic device (101) can change from the released state to the fastened state.

[0103] Referring to FIGS. 5c and 5d, while the electronic device (101) changes from a fastened state to an unfastened state, the second fastening portion (420) can be rotated in a first rotational direction (401) toward the first fastening portion (410) within the second portion (442). For example, the second housing (312) of the core (310) coupled with the frame (330) can be rotated by the user in the first rotational direction (401) with respect to the first housing (311). The second fastening portion (420) of the second housing (312) can be rotated by the user in the first rotational direction (401) with respect to the first fastening portion (410) of the first housing (311). The second fastening portion (420) can be moved from the second region (442b) to the first region (442a). The second fastening portion (420) may be configured to be positioned within the first region (442a) so that the core (310) can move in a second direction (302) opposite to the first direction (301). The second fastening portion (420) may be positioned within the first region (441a) connected to the first portion (441), so that the electronic device (101) can change from the fastened state to the released state.

[0104] According to the above-described embodiment, the electronic device (101) may be configured such that the core (310) is detachably coupled to the frame (330) of the strap (320) by including a first fastening portion (410) and a second fastening portion (420) movable with respect to the first fastening portion (410). The frame (330) may include a first guide groove (430) configured to receive the first fastening portion (410) and a second guide groove (440) guiding movement of the second fastening portion (420), thereby providing a variety of user experiences to a user of the electronic device (101).

[0105] Figures 6a and 6b illustrate exemplary electronic devices.

[0106] Referring to FIGS. 6A and 6B, the electronic device (101) may include a core (310) including a first fastening portion (410) and a second fastening portion (420) movable with respect to the first fastening portion (410).

The frame (330) may include a first guide groove (430) for receiving the first fastening portion (410). The frame (330) may include a second guide groove (440) including a first portion (441) for passing through the second fastening portion (420), and a second portion (442) extending from the first portion (441) and guiding the movement of the second fastening portion (420) passing through the first portion (441) with respect to the first fastening portion (410).

[0107] According to one embodiment, the core (310) may further include a first housing (311) defining a first fastening portion (410), and a second housing (312) defining a second fastening portion (420) and coupled with the first housing (311) to rotate in a first rotational direction (401) and a second rotational direction (402) opposite to the first rotational direction (401) with respect to the first housing (311). The second housing (312) may include a first through hole (610) exposing at least a portion of the second fastening portion (420), and a second through hole (620) spaced from the first through hole (610) and moving along the second housing (312) to expose at least a portion of the first housing (311).

[0108] For example, the first through hole (610) and the second through hole (620) may be formed on the second surface (310b) of the core (310). For example, the first through hole (610) and the second through hole (620) may pass through a wheel (e.g., a wheel (460) of FIG. 4A) of the second housing (312). For example, the first through hole (610) and the second through hole (620) may be configured to guide the position of the second fastening portion (420) with respect to the first housing (311), thereby allowing a user of the electronic device (101) to identify a fastening state of the electronic device (101) and a disengagement state of the electronic device (101).

[0109] For example, referring to FIG. 6A, while the electronic device (101) is in the unlocked state, the first through hole (610) may be positioned at a point corresponding to the central axis (C) of the frame (330). For example, referring to FIG. 6B, while the electronic device (101) is in the locked state, the second through hole (620) may be positioned at a point corresponding to the central axis (C) of the frame (330). However, the present invention is not limited thereto. The second housing (212) including the second locking portion (420) may include a structure that guides the user to move the second locking portion (420) relative to the first locking portion (410) with respect to the first housing (311) including the first locking portion (410), thereby providing the user with various user experiences.

[0110] According to the above-described embodiment, the electronic device (101) may be configured to guide the user to the position of the second fastening portion (420) with respect to the first fastening portion (410) by including through holes (610, 620) and to allow the user to easily identify the fastening state and the unfastening state of the electronic device (101).

[0111] Figure 7 illustrates a portion of the core of an exemplary electronic device.

[0112] Referring to FIGS. 6A and 6B, a core (310) of an electronic device (e.g., the electronic device (101) of FIG. 1) may include a core (310) including a first fastening portion (410) and a second fastening portion (420) movable with respect to the first fastening portion (410).

[0113] According to one embodiment, the core (310) may further include an elastic structure (710) configured to guide movement of a second fastening portion (420) relative to the first fastening portion (410). The second fastening portion (420) may be configured to pressurize the elastic structure (710) by being moved in a first rotational direction (401) relative to the first fastening portion (410) by a first portion (e.g., a first portion (441) of FIG. 4b) of a second guide groove (e.g., a second guide groove (440) of FIG. 4b). The second fastening portion (420) may be configured to move in a second rotational direction (402) opposite to the first rotational direction (401) with respect to the first fastening portion (410) by the elastic structure (710) within the second portion (e.g., the second portion (442) of FIG. 4b) after passing through the first portion (441).

[0114] For example, in a disassembled state of the electronic device (101), the second fastening portion (420) can be separated from the first fastening portion (410) by the elastic force of the elastic structure (710).

[0115] For example, while the electronic device (101) changes from a disassembled state to an assembled state, since at least a part of the first fastening portion (410) is positioned within the first guide groove (e.g., the first guide groove (430) of FIG. 4B), the second fastening portion (420) can be pressed by the first part (441) of the second guide groove (440). As the elastic structure (710) is compressed by the first part (441), the second fastening portion (420) can be moved in the first rotational direction (401) toward the first fastening portion (410).

[0116] For example, while the electronic device (101) is changing from a disengaged state to a engaged state, the second engaging portion (420) may pass through the first portion (441) and be positioned within the second portion (442). Since the pressure by the first portion (441) is released, the second engaging portion (420) may move in a second rotational direction (402) opposite to the first rotational direction (401) from a first region (e.g., the first region (442a) of FIG. 4B) of the second portion (442) to a second region (e.g., the second region (442b) of FIG. 4B) by the restoration force of the elastic structure (710). For example, a first housing (311) may include a first fastening portion (410), and a second housing (312) rotatable with respect to the first housing (311) may include a second fastening portion (420). As a user rotates the first housing (311) in a fastened state of the electronic device (101), the elastic structure (710) may be compressed. As the elastic structure (710) is compressed, the second fastening portion (420) may move with respect to the first fastening portion (410). By the user's compression of the elastic structure (710), the second fastening portion (420) may move with respect to the first fastening portion (410), thereby changing the electronic device (101) from a fastened state to a disengaged state.

[0117] According to the above-described embodiment, the electronic device (101) can provide various user experiences to the user of the electronic device (101) by including an elastic structure (710) configured to move the second fastening portion (420) with respect to the first fastening portion (410).
