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).

[0044] 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)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0075] Referring to FIGS. 3A and 3B, a wearable electronic device (301) according to one embodiment (e.g., the wearable electronic device (201) of FIG. 2A) may include a body (300) (e.g., the body (200) of FIG. 2A) including a housing (e.g., the housing (210) of FIG. 2A), a first strap (350a), a second strap (350b), a strap fastening structure (370) (e.g., the strap fastening structure (270) of FIG. 2A), and a fastening member (380) (e.g., the fastening member (280) of FIG. 2A).

[0076] In one embodiment, the body (300) may include various component elements for the operation of the wearable electronic device (301). The body (300) may include a housing forming an exterior. In one embodiment, a first lug (306a) to which a first strap (350a) is detachably connected may be formed in a first portion of the housing, and a second lug (306b) to which a second strap (350b) is detachably connected may be formed in a second portion. In one embodiment, at least a portion of the straps (350a, 350b) may be configured to be connected or fixed to the first lug (306a) and the second lug (306b).

[0077] In one embodiment, the straps (350a, 350b) may include a first strap (350a) and a second strap (350b). In one embodiment, the first strap (350a) and the second strap (350b) may be formed separately, but may also be formed as a single connected strap, unlike as shown in the drawing. For convenience of explanation, the wearable electronic device (301) will be described below with a focus on an embodiment in which the wearable electronic device (301) includes a first strap (350a) and a second strap (350b) that are separated from each other.

[0078] In one embodiment, the first strap (350a) and the second strap (350b) may be formed of a magnetic metal material. For example, the first strap (350a) and the second strap (350b) may include a metal material. In another embodiment, the first strap (350a) and the second strap (350b) may be formed of different materials. For example, the first strap (350a) may be formed of a first material having magnetism, and the second strap (350b) may be formed of a second material having non-magnetism.

[0079] In one embodiment, the second strap (350b) may include a plurality of fastening grooves (353) that are concavely formed on the surface of the second strap (350b). In one embodiment, the plurality of fastening grooves (353) may be spaced apart from each other along the length of the second strap (350b). In one embodiment, the spacing between the plurality of fastening grooves (353) may be constant.

[0080] In one embodiment, the strap fastening structure (370) can fasten the first strap (350a) and the second strap (350b) to each other. For example, the strap fastening structure (370) can be connected to an end of the first strap (350a) and can support at least a portion of the second strap (350b) to fix the relative connection position of the second strap (350b) with respect to the first strap (350a). In one embodiment, the fastening member (380) can be connected to an end of the second strap (350b). In one embodiment, the fastening member (380) can include a magnetic material. In one embodiment, when the first strap (350a) is formed of a magnetic metal material, the fastening member (380) can be attached to the first strap (350a) as shown in FIG. 3a to bring the end of the second strap (350b) into close contact with the first strap (350a).

[0081] In one embodiment, the strap fastening structure (370) may include a fixed body (371) and a rotating body (372) that is rotatably connected to the fixed body (372). In one embodiment, the rotating body (372) may rotate about a rotational axis (A) with respect to the fixed body (371). For example, the rotating body (372) may be rotatably connected to the fixed body (371) via a hinge structure (373) that is arranged parallel to the rotational axis (A).

[0082] In one embodiment, the strap fastening structure (370) can change its state between a first state (e.g., a closed state in FIG. 3A) and a second state (e.g., an open state in FIG. 3B) depending on the rotational body (372) relative to the fixed body (371). For example, with respect to the rotational axis (A), the rotational body (372) can form a minimum angle relative to the fixed body (371) in the first state of the strap fastening structure (370), and can form a maximum angle relative to the fixed body (372) in the second state of the strap fastening structure (370). In one embodiment, the strap fastening structure (370) can limit the relative movement of the second strap (350b) relative to the first strap (350a) in the first state. In one embodiment, the strap fastening structure (370) allows relative movement of the second strap (350b) with respect to the first strap (350a) in the second state, thereby allowing the size of the space formed by the first strap (350a) and the second strap (350b), e.g., the space in which the first strap (350a) and the second strap (350b) surround the user's body, to be adjusted.

[0083] In one embodiment, the fixed body (371) may include a seating space (371) in which at least a portion (e.g., a rotating portion (3723)) of the rotating body (372) is seated in the first state. In one embodiment, the fixed body (371) may include a protruding portion (3711) that protrudes from the seating space (371) in a first direction (e.g., a +W direction in FIG. 3B). An end of the protruding portion (3711) may be positioned at a higher position than an upper surface of the fixed body (371) (e.g., an upper surface of the fixed body (371) facing the +W direction in FIG. 3B).

[0084] In one embodiment, the rotating body (372) may include a rotating portion (3723) connected to the fixed body (371) through a hinge structure (373), and a loop portion (3721) that wraps the second strap (350b) in a loop shape on the upper portion of the rotating portion (3723) (e.g., in the +W direction of FIG. 3b). The loop portion (3721) may form a hollow portion (e.g., the hollow portion (3720) of FIG. 4a) through which the second strap (350b) can pass together with the upper surface of the rotating portion (3723). In one embodiment, the rotating portion (3723) may be formed with an opening (3722) that is formed to penetrate in the thickness direction so as to communicate with the hollow portion formed by the loop portion (3721).

[0085] In one embodiment, the rotating portion (3723) of the rotating body (372) can be selectively seated in the seating space (3710) formed by the fixed body (371) depending on the state of the strap fastening structure (370). For example, in a first state of the strap fastening structure (370) as in FIG. 3A, the rotating portion (3723) of the rotating body (372) can be seated in the seating space (3710), and in a second state of the strap fastening structure (370) as in FIG. 3B, the rotating portion (3723) of the rotating body (372) can be located outside the seating space (3710). In one embodiment, the thickness of the rotating portion (3723) can be substantially the same as the height of the seating space (3710).

[0086] In one embodiment, in the first state of the strap fastening structure (370), the protruding portion (3711) may be positioned within the opening (3722). In this case, an end of the protruding portion (3711) (e.g., an end of the protruding portion (3711) facing the +W direction of FIG. 3B) may protrude above the rotating portion (3723) and be positioned within the hollow space formed by the loop portion (3721). In the first state of the strap fastening structure (370), the protruding portion (3711) may contact the surface of the first strap (350a) within the hollow space. As illustrated in FIG. 4a, when the protruding portion (3711) is positioned to overlap one of the plurality of fastening grooves (353) formed in the first strap (350a), the protruding portion (3711) can be inserted into the fastening groove (353) to restrict the movement of the first strap (350a) with respect to the rotating body (372). Accordingly, in the first state of the strap fastening structure (370), the relative movement of the first strap (350a) with respect to the second strap (350b) can be prevented or reduced.

[0087] Hereinafter, a strap fastening structure (370) according to one embodiment will be described in detail with reference to FIGS. 4a, 4b, 4c, 4d, 4e, and 4f.

[0088] In one embodiment, the strap fastening structure (370) may include a fixed body (371), a rotating body (372) rotatably connected to the fixed body (371) about a rotation axis (A), a first magnet (375) disposed on the rotating body (372), and a second magnet (374) disposed on the fixed body (371).

[0089] In one embodiment, the fixed body (371) may include a fixed portion (3712) connected to the first strap (350a), a support portion (3713) connected to the fixed portion (3712) and forming a seating space (3710), a protruding portion (3711), and a hinge portion (3714) connected to the support portion (3713) and having a hinge structure (373) arranged therein.

[0090] In one embodiment, the fixed portion (3712) may be fixed to an end of the first strap (350a). In one embodiment, the upper surface of the fixed portion (3712) (e.g., the upper surface of the fixed portion (3712) facing the +W direction of FIG. 4b) may form a plane substantially identical to the upper surface of the rotating portion (3723) of the rotating body (372) based on the first state of the strap fastening structure (370).

[0091] In one embodiment, the support portion (3713) may be connected to the fixed portion (3712). The support portion (3713) may form an inwardly concave seating space (3710). An upper surface of the support portion (3713) forming the seating space (3710) may be positioned at a relatively lower position (e.g., a position based on the +W direction of FIG. 4d) compared to the fixed portion (3712). In one embodiment, the support portion (3713) may be provided with a protruding portion (3711) that protrudes from the seating space (3710) in a first direction (e.g., a direction parallel to +W of FIG. 4d). In one embodiment, the protruding portion (3711) may be positioned at the center of the width direction (e.g., the V-axis direction of FIG. 4d) of the support portion (3713). However, it should be noted that the position of the protruding portion (3711) is not necessarily limited to this and may change depending on the design of the strap fastening structure (370).

[0092] In one embodiment, the support portion (3713) may include one or more receiving spaces (37131, 37132) formed on the lower side of the settling space (3710). The one or more receiving spaces (37131, 37132) may be formed in a second direction (e.g., the -W direction of FIG. 4d) opposite to the first direction in which the protruding portion (3711) protrudes with respect to the settling space (3710). One or more second magnets (3741, 3742) may be arranged in the receiving spaces (37131, 37132).

[0093] In one embodiment, the hinge portion (3714) may be connected to the support portion (3713) so as to be opposite to the fixed portion (3712) with the settling space (3710) therebetween. A hinge structure (373) may be arranged on the hinge portion (3714) for rotatably connecting the fixed body (371) and the rotary body (372) about the rotation axis (A). In one embodiment, a stopper (3715) may be formed on the hinge portion (3714) to limit the rotation angle of the rotary body (372) with respect to the fixed body (371). For example, the stopper (3715) may be formed to protrude on the outer surface of the hinge portion (3714) and may come into contact with a portion (3725) of the rotary portion (3723) of the rotary body (372) in the second state of the strap fastening structure (370). The stopper (3715) can limit the rotation of the rotating body (372) to a set angle or more with respect to the fixed body (371). In one embodiment, the stopper (3715) may be formed on the rotating portion (3723) of the rotating body (372) and configured to contact the hinge portion in the second state of the strap fastening structure (370). However, it should be noted that the structure of the stopper (3715) described above is exemplary, and the stopper (3715) may be formed in various shapes to limit the rotation angle of the rotating body (372) with respect to the fixed body (371).

[0094] In one embodiment, the rotating body (372) may include a rotating portion (3723) rotatably connected to the fixed body (371) via a hinge structure (373), and a loop portion (3721) connected to an upper portion of the rotating portion (3723) and wrapping around a second strap (350b) positioned at an upper portion of the rotating portion (3723). In one embodiment, the loop portion (3721) may form a hollow (3720) through which the second strap (350b) passes together with an upper surface of the rotating portion (3722) (e.g., an upper surface of the rotating portion (3722) facing the +W direction of FIG. 4A).

[0095] In one embodiment, the rotating portion (3723) may be formed with an opening (3722) that penetrates in the thickness direction to communicate with the hollow (3720). In one embodiment, the opening (3722) may be formed at an end of the rotating portion (3722) opposite to the rotation axis (A), such that the protruding portion (3711) may be inserted according to the rotation of the rotating body (372) with respect to the fixed body (371). In one embodiment, the opening (3722) may be formed at a position of the rotating portion (3722) corresponding to the protruding portion (3711). For example, when the protruding portion (3711) is formed at the center in the width direction (e.g., the V-axis direction of FIG. 4d) of the fixed body (371), the opening (3722) may be formed at the center in the width direction (e.g., the V-axis direction of FIG. 4d) of the rotating portion (3723).

[0096] In one embodiment, the first magnet (375) may be placed in the rotating body (371). For example, the rotating body (371) may form an internal space, and the first magnet (375) may be placed in the internal space of the rotating body (371). In one embodiment, the first magnet (375) may be provided in multiple pieces. For example, the first magnet (375) may be provided as a first-first magnet (3751) and a first-second magnet (3752), and may be placed side by side with an opening (3722) therebetween. In this case, a pair of first covers (3772) may be placed on the rotating body (371) to cover the first-first magnet body (3751) and the first-second magnet body (3752), respectively, so that the first-first magnet body (3751) and the first-second magnet body (3751) are not exposed to the outside of the rotating body (371).

[0097] In one embodiment, when the second strap (350b) is formed of a metal material having magnetism, the first magnet (375) can apply a magnetic force to a portion of the second strap (350b) located within the hollow (3720). In one embodiment, the magnetic force applied by the first magnet (375) to the portion of the second strap (350b) located within the hollow (3720) can maintain a relative position of the second strap (350b) with respect to the rotating body (372). In this case, when the user does not apply a force greater than a certain level to move the second strap (350b) along the hollow (3720), the position of the portion of the second strap (350b) located within the hollow (3720) is maintained, so that the portion of the second strap (350b) with respect to the rotating body (372) can be maintained. In one embodiment, the magnetic force acting between the first magnet body (375) and the second strap (350b) portion located within the hollow (3720) may perform a guiding function to allow the user to adjust the straps (350a, 350b) to an appropriate length for fastening to the body. For example, when the user adjusts the second strap (350b) to an appropriate position with respect to the rotating body (372), the relative rotational state of the rotating body (372) with respect to the fixed body (371) may be changed by the magnetic force acting on the first magnet body (375), for example, the relative position of the second strap (350b) with respect to the rotating body (372) may be maintained constant during the process in which the strap fastening structure (370) changes from the second state to the first state.

[0098] In one embodiment, the second magnet (374) may be placed in the fixed body (371). For example, the second magnet (374) may be placed in the receiving spaces (37131, 37132) formed in the supporting portion (3713) of the fixed body (371). In one embodiment, the second magnet (374) may be provided in multiple pieces. For example, the second magnet (374) may be provided as a second-first magnet (3741) and a second-second magnet (3742), and may be placed in the first receiving space (37131) and the second receiving space (37132) formed in the supporting portion (3713), respectively. In one embodiment, when the second magnet body (374) is provided as a pair, the second-first magnet body (3741) and the second-second magnet body (3472) may be arranged side by side with the protruding portion (3711) therebetween. In this case, a pair of second covers (3771) may be arranged on the fixed body (371) to cover the second-first magnet body (3741) and the second-second magnet body (3742), respectively, so that the second-first magnet body (3741) and the second-second magnet body (3742) are not exposed to the outside of the support portion (3722).

[0099] In one embodiment, one or more second magnets (374) may be arranged to exert an attractive force on one or more first magnets (375) in the first state of the strap fastening structure (370). For example, the second-first magnet (3741) may be arranged on the fixed body (371) to exert an attractive force on the first-first magnet (3751), and the second-second magnet (3742) may be arranged on the fixed body (371) to exert an attractive force on the first-second magnet (3752). In one embodiment, the second magnet (374) arranged on the fixed body (371) may exert an attractive force on the first magnet (375) arranged on the rotating body (372), thereby performing a function of maintaining the first state of the strap fastening structure (370) (e.g., a closed state as in FIG. 4b). For example, due to the mutually acting attractive force between the first magnet body (375) and the second magnet body (374), in the first state of the strap fastening structure (370), the rotating part (3723) of the rotating body (372) can be brought into close contact with the support part (3713) of the fixed body (371), and the end of the protruding part (3711) located in the hollow (3720) can be brought into closer contact with the surface of the second strap (350b). In one embodiment, when the surface of the protruding part (3711) is engaged with the fastening groove (353) of the second strap (350b) located in the hollow (3720), the engagement of the protruding part (3711) with the fastening groove (353) of the second strap (350b) can be more firmly maintained due to the mutually acting attractive force between the first magnet body (375) and the second magnet body (374).

[0100] In one embodiment, the strap fastening structure (370) may further include a catch structure to more firmly maintain the first state (e.g., closed state) of the rotating body (372) with respect to the fixed body (371). For example, the fixed body (371) may include one or more catch members (3716) protruding from the fixed portion (3712) toward the seating space (3710), as illustrated in FIG. 4d, and the rotating body (372) may include one or more catch grooves (3726) formed on the outer surface of the rotating portion (3723) facing the fixed portion (3712) in the first state of the strap fastening structure (370), as illustrated in FIG. 4e. In one embodiment, based on the first state of the strap fastening member (3716), the engaging member (3716) can be engaged with the engaging groove (3726) to limit the rotation of the rotating body (372) relative to the fixed body (371).

[0101] In one embodiment, the strap fastening structure (370) may be configured to selectively release the engagement state of the catching member (3716) with respect to the catching groove (3726). For example, the fixed body (371) may be formed in the fixed portion (3712) and may include one or more insertion grooves (3717) into which one or more catching members (3716) are movably inserted, respectively. In one embodiment, an elastic member may be disposed within the insertion groove (3717) to exert an elastic force to urge the catching member (3716) in a direction toward the seating space (3710) (e.g., +U direction in FIG. 4F). In one embodiment, although not illustrated in the drawing, at least a portion of the insertion groove (3717) may be opened to the outside of the fixed body (371), and a trigger may be connected to the catching member (3716) that is exposed to the open insertion groove (3717) portion and is operable by a user.

[0102] Fig. 5a is a cross-sectional view taken along line Va-Va of Fig. 4b, illustrating a second state of a strap fastening structure according to an embodiment. Fig. 5b is a cross-sectional view taken along line Vb-Vb of Fig. 4b, illustrating a second state of a strap fastening structure according to an embodiment. Fig. 6a is a cross-sectional view taken along line Va-Va of Fig. 4b, illustrating a first state of a strap fastening structure according to an embodiment. Fig. 6b is a cross-sectional view taken along line Vb-Vb of Fig. 4b, illustrating a second state of a strap fastening structure according to an embodiment.

[0103] Hereinafter, with reference to FIGS. 5a to 5d, the fastening operation between the first strap (350a) and the second strap (350b) through the strap fastening structure (370) will be described.

[0104] In the second state (e.g., the second state of FIG. 2b) of the strap fastening structure (370) as shown in FIGS. 5a and 5b, the rotating portion (3723) of the rotating body (371) can be positioned outside the seating space (3710) of the fixed body (371). The first strap (350a) is inserted so as to pass through the hollow (3720) formed by the rotating portion (3723) and the loop portion (3721) of the rotating body (372), and its position can be adjusted relative to the rotating body (371) along the movement direction (C). In one embodiment, the first magnet (375) disposed on the rotating portion (3723) can apply a magnetic force to a portion of the second strap (350b) located in the hollow (3720), thereby reducing or preventing the phenomenon of the second strap (350b) slipping along the hollow (3720) without an external force applied by the user. For example, when the relative position of the second strap (350b) with respect to the rotating body (372) is adjusted by the user, the second magnet (350) can apply a magnetic force to a portion of the second strap (350b) located in the hollow (3720) to maintain the position of the second strap (350b) with respect to the rotating body (372).

[0105] In a first state of the strap fastening structure (370) such as FIGS. 5c and 5d (e.g., the first state of FIG. 2a), the rotating part (3723) of the rotating body (372) can be seated within the seating space (3710) of the fixed body (371). The first magnet (374) disposed on the fixed body (371) can exert a mutual attraction with the second magnet (375) disposed on the rotating body (372) to bring the rotating part (3723) into close contact with the seating space (3710). The protruding part (3711) of the fixed body (371) can be inserted into the opening (3722) formed on the rotating part (3723), and the end of the protruding part (3711) can be positioned to protrude into the hollow (3720). The end of the protruding portion (3711) can be inserted into and engaged with the fastening groove (353) formed in the portion of the second strap (350b) located in the hollow (3720). Through the interlocking connection of the protruding portion (3711) to the fastening groove (353) of the second strap (350b), the relative movement of the second strap (350b) with respect to the rotating body (372) can be restricted. Accordingly, the relative positions of the first strap (350a) connected to the fixed body (371) by the strap fastening structure (370) and the second strap (350b) connected to the rotating body (372) can be fixed.

[0106] In one embodiment, in the first state of the strap fastening structure (370), the catching member (3716) arranged on the fixed body (371) can be inserted into the fixing space (3710) to be engaged with a catching groove (3726) formed on the surface of the rotating body (372). Due to the engaging connection of the catching member (3716) to the catching groove (3726), the release of the first state of the strap fastening structure (370) can be reduced or prevented.
