[0080] Fig. 4 is an exploded perspective view of an electronic device for explaining a fastening structure of a housing and a strap of an electronic device according to one embodiment. Fig. 5 is an exploded perspective view of an electronic device for explaining a fastening structure of a housing and a strap of an electronic device according to one embodiment.

[0081] The electronic device (400) of FIGS. 4 and 5 may correspond to the electronic device (100) of FIGS. 1 and 2 and the electronic device (300) of FIG. 3.

[0082] Referring to FIGS. 4 and 5, the electronic device (400) may include a housing (410), a fastening member (420), a bracket (430), at least one body magnet (440), a strap (450), and a rear plate (460). At least one of the components of the electronic device (400) may be identical to or similar to at least one of the components of the electronic device (100) of FIGS. 1 and 2 and the electronic device (300) of FIG. 3, and any overlapping descriptions will be omitted below.

[0083] According to one embodiment, the housing (410) may include a cavity portion (412) formed to be open toward the side direction of the electronic device (400). The cavity portion (412) may include a side wall (412-1) and a plurality of recesses (412-2, 412-3) formed in the side wall (412-1).

[0084] For example, referring to FIG. 4, a side wall (412-1) of a housing (410) may be defined to extend primarily along the y and z directions, and an outer surface exposed to the outside of the housing (410) may be formed by a cavity (e.g., a cavity portion 412). The first side and the second side of the housing (410) may be arranged in directions intersecting each other (e.g., an x-direction and a y-direction, i.e., an xy-plane), and each of the x and y directions intersects the z-direction. The z-direction may be considered a thickness direction of the electronic device (400) and its components.

[0085] In one embodiment, the housing (410) may include a side surface (e.g., sidewall 412-1), a first side surface that protrudes further than the side surface (e.g., is disposed in the -z direction as a portion of the upper plate shape in the xy plane), and a second side surface that protrudes further than the side surface (e.g., is disposed in the +z direction as a portion of the lower plate shape in the xy plane and is at least partially spaced apart from the first side surface along the z direction), wherein the protruding portions of the first and second side surfaces may be formed to define or enclose a space (e.g., a cavity portion 412) together with the side surface. For example, referring to FIG. 4, the cavity portion (412-1) may be open to the exterior of the housing (410) in the +x direction, the -y direction, and the +y direction.

[0086] According to one embodiment, the fastening member (420) may include a button member (420-1) and a hook member (420-2). The hook member (420-2) may be disposed within the cavity portion (412) and engaged with a strap (450) introduced into the cavity portion (412). The button member (420-1) is coupled with the hook member (420-2) and may apply force to the hook member (420-2) toward the front direction (e.g., +z direction) of the electronic device (400), thereby causing the hook member (420-2) to move toward the front of the electronic device (400).

[0087] According to one embodiment, a first spring (471) may be disposed between the hook member (420-2) and the button member (420-1). The first spring (471) disposed between the hook member (420-2) and the button member (420-1) may apply an elastic force to the hook member (420-2) and the button member (420-1) that are coupled to each other. According to one embodiment, the first spring (471) may be omitted. According to one embodiment, a second spring (472) may be disposed between the hook member (420-2) and the cavity portion (412). The second spring (472) may apply an elastic force to the hook member (420-2) disposed in the cavity portion (412). The first spring (471) and / or the second spring (472) may include, for example, a coil spring and / or a plate spring, but are not limited thereto.

[0088] By positioning the structure for fastening between the strap (450) and the housing (410), which will be described later, such as the hook member (420-2) and the button member (420-1), in the edge space of the main body of the electronic device (400), the size of the space required for fastening between the housing (410) and the strap (450) can be reduced. The main body can be defined together by the housing and the fastening member, and can have overall dimensions in each of the thickness direction and the plane direction. If the button member or the like is disposed on the strap, the thickness of the strap increases and the flexibility of the strap decreases, so that the usability of the electronic device (400) may be reduced when the electronic device (400) is worn by the user. In contrast, when a mechanical structure, such as the button member (420-1) according to one embodiment, is disposed within the electronic device (400) having a predetermined thickness, the usability and aesthetic appeal of the electronic device (400) can be secured.

[0089] In addition, since the hooking structure of the hook member (420-2) according to one embodiment can be formed so as to secure a predetermined length along the edge of the main body of the electronic device (400) within the common portion (412), when the hook member (420-2) is fastened to the strap (450), the area of ​​the portion where the force for fastening the hook member (420-2) and the strap (450) acts can increase. In addition, the force for fastening the hook member (420-2) and the strap (450) can act on a wider area toward the front (e.g., +z direction) or the rear (e.g., -z direction) opposite to the front of the electronic device (400), and accordingly, the housing (410) and the strap (450) can be fastened more stably.

[0090] In one embodiment, the bracket (430) can secure the button member (420-1) to the housing (410) so that the fastening member (420) does not come off from the housing (410). The bracket (430) can be secured to the housing (410) by a screw (432). In one embodiment, the electronic device (400) may not include the bracket (430). For example, as shown in FIGS. 7C to 7F , the electronic device (400) can be assembled to the housing (410) without the bracket (430).

[0091] According to one embodiment, at least one body magnet (440) may be disposed in the housing (410), and may be disposed at a position corresponding to at least one strap magnet (454) to be described later when the strap (450) is fastened to the housing (410). Accordingly, for example, when the strap (450) is fastened to the housing (410), an attractive force may be applied between the at least one body magnet (440) and the at least one strap magnet (454). When an attractive force is applied between the at least one body magnet (440) and the at least one strap magnet (454), the user may conveniently fasten the strap (450) to the housing (410). Alternatively, for example, when the strap (450) is fastened to the housing (410), a repulsive force may be applied between the at least one body magnet (440) and the at least one strap magnet (454). When a repulsive force is applied between at least one body magnet (440) and at least one strap magnet (454), the user can conveniently separate the strap (450) from the housing (410).

[0092] According to one embodiment, magnets (440) having multiple polarities may be arranged in the housing (410) and may be arranged at positions corresponding to the plurality of strap magnets (454) described later when the strap (450) is fastened to the housing (410). In this case, the magnets (440) and the strap magnets (454) may be arranged so that magnets having different polarities are arranged at positions corresponding to each other. For example, the magnets (440) may be arranged in the order of N pole, S pole, and N pole, and the strap magnets (454) corresponding to the magnets (440) may be arranged in the order of S pole, N pole, and S pole. Accordingly, when the strap (450) is inserted into the housing (410) in the correct direction, an attractive force may be applied between the magnets (440) and the strap magnets (454), and when the strap (450) is inserted into the housing (410) in a different direction, a repulsive force may be applied between the magnets (440) and the strap magnets (454). In the above, it has been described that a plurality of magnets (440) having a plurality of polarities and a plurality of strap magnets (454) having a plurality of polarities are arranged, but the present invention is not limited thereto. For example, one magnet (440) having a plurality of polarities and one strap magnet (454) having a plurality of polarities may be arranged.

[0093] According to one embodiment, the strap (450) may include a strap body (455), a strap adapter (451) as a strap connector, and at least one strap magnet (454). The strap (450) may correspond to the fastening members (150, 160) of FIGS. 1 and 2 and the fastening members (395, 397) of FIG. 3.

[0094] According to one embodiment, the strap body (455) is connected to a strap adapter (451) and can be fastened to the housing (410) by the strap adapter (451).

[0095] According to one embodiment, a strap adapter (451) is disposed on one side of the strap body (455) and can be fastened to a hook member (420-2) of the housing (410). The strap adapter (451) can include a fastening portion (452) and a plurality of protruding guides (453).

[0096] In one embodiment, the strap adapter (451) may have a shape corresponding to the hollow portion (412) of the housing (410), and when the strap (450) is fastened to the housing (410), at least a portion of the strap adapter (451) may be surrounded by the hollow portion (412) of the housing (410). For example, when the strap (450) is fastened to the housing (410), an edge portion of the strap adapter (451) may be surrounded by the hollow portion (412) of the housing (410).

[0097] According to one embodiment, a strap (450) including a strap body (455) and a strap adapter (451) can be manufactured by injection molding using a strap adapter (451). For example, the strap adapter (451) can be formed of a metal material, and the strap adapter (451) can be injection molded using a rubber material, thereby forming the strap (450). However, the material of the strap body (455) is not limited to a rubber material. For example, the strap (450) can be manufactured by forming the strap adapter (451) on a strap body (455) made of a fabric material through bonding and pressing. For example, a strap (450) in which the strap body (455) and the strap adapter (451) are integrally formed can also be manufactured.

[0098] According to one embodiment, the fastening portion (452) (e.g., the joining portion) of the strap adapter (451) through which the strap (450) is fastened to the housing (410) is formed with a hook structure, so that when a portion of the strap (450) is introduced into the hollow portion (412) of the housing (410), it can be fastened to the hook member (420-2) of the housing (410).

[0099] According to one embodiment, a plurality of protruding guides (453) of the strap adapter (451) are inserted into a plurality of recesses (412-2, 412-3) formed in the hollow portion (412) of the housing (410), thereby preventing the strap (450) from moving in the hollow portion (412) of the housing (410) after the strap (450) is fastened to the housing (410).

[0100] According to one embodiment, at least one strap magnet (454) may be disposed on the strap adapter (451) and may be disposed at a position corresponding to at least one body magnet (440) when the strap (450) is fastened to the housing (410). Accordingly, when the strap (450) is fastened to the housing (410), an attractive force may be applied between the at least one body magnet (440) and the at least one strap magnet (454).

[0101] Meanwhile, in FIG. 4, the electronic device (400) is described as including at least one body magnet (440) and at least one strap magnet (454), but is not limited thereto. For example, the electronic device (400) may not include at least one body magnet (440) and at least one strap magnet (454).

[0102] A rear plate (460) according to one embodiment may be arranged to cover one side of the electronic device (400) facing the rear (e.g., -z direction). For example, the rear plate (460) may be formed to include a hole (e.g., an enclosed opening or an enclosed through-hole) surrounding the button member (420-1) such that a portion of the button member (420-1) is exposed to the outside of the electronic device (400). The enclosed opening may be open at the top and bottom surfaces of the rear plate (460). The enclosed opening may correspond to an enclosed opening at the first side portion of the housing (410), and the two enclosed openings may be aligned with each other such that a hook and a button structure may be connected at the aligned opening.

[0103] The housing (410) of the electronic device (400) according to one embodiment may not include a separate lug for fastening the strap (450), and the strap (450) may be easily fastened and detached from the housing (410).

[0104] The fastening structure of the housing (410) and the strap (450) of the electronic device (400) according to one embodiment can improve the efficiency of the space in which components can be placed within the electronic device (400).

[0105] The fastening structure of the housing (410) and the strap (450) of the electronic device (400) according to one embodiment can be implemented in various designs, and user convenience can be enhanced when replacing the strap (450).

[0106] The fastening structure of the housing (410) and the strap (450) of the electronic device (400) according to one embodiment can be implemented using various materials and designs. For example, by fastening the strap (450) to the housing (410) that does not include a lug, the shape of the housing (410) of the electronic device (400) can be formed in various shapes other than a circle (e.g., cushion shape, polygonal shape, rectangular shape, etc.).

[0107] The fastening structure of the housing (410) and the strap (450) of the electronic device (400) according to one embodiment can be manufactured with a high yield, and the manufacturing cost can be reduced. For example, since the strap (450) has a simple structure with a complex driving part eliminated, the manufacturing yield is improved when molding the strap (450), and by reducing the number of backup molds for mass production in a short period of time, there is an effect of reducing the mold cost for manufacturing the housing (410) and the strap (450).

[0108] FIG. 6 is a drawing showing an example in which a button member and a hook member are arranged in a common portion of a housing according to one embodiment.

[0109] Referring to FIG. 6, a fastening member (420) according to one embodiment may be at least partially disposed in a hollow portion (412) of a housing (410) by coupling a button member (420-1) and a hook member (420-2). The fastening member (420) coupled to the housing (410) may be exposed to the outside of the housing (410) in the hollow portion (412) that is open to the outside of the housing (410) in the x-direction.

[0110] In one embodiment, a button member (420-1) may be inserted into a cavity portion (412) of the housing (410) through an opening (414) formed in or by a portion of the housing (410) (e.g., open toward the rear) of the electronic device (400) in the rear direction (e.g., -z direction). In one embodiment, a hook member (420-2) may be disposed below the opening (414) in the cavity portion (412). In one embodiment, a second spring (not shown) may be disposed between the hook member (420-2) and the cavity portion (412).

[0111] According to one embodiment, a button member (420-1) introduced into a cavity portion (412) through an opening (414) can be coupled with a hook member (420-2) disposed in the cavity portion (412). For example, the button member (420-1) can be assembled with the hook member (420-2) by inserting a protruding portion (420-3) of the button member (420-1) into a recessed portion (420-4) of the hook member (420-2). For example, a first spring (471) may be disposed between the button member (420-1) and the hook member (420-2), but is not limited thereto.

[0112] According to one embodiment, the fastening member (420) may be composed of a button member (420-1) and a hook member (420-2). The button member (420-1) may be introduced into the cavity (412) through the opening (414), and the hook member (420-2) may be disposed in the cavity (412) from the side of the electronic device (400). Accordingly, even if the space (or volume) of the cavity (412) is formed small, the fastening member (420) may be effectively disposed in the housing (410). The button member (420-1) may extend from the rear surface of the housing (410) to the outside of the housing (410), and may extend from the cavity to the inside of the housing (410) through the opening (414). That is, the opening (414) may be open at the rear surface and the front surface of the protruding (plate) portion of the housing (410).

[0113] FIG. 7a is a cross-sectional view illustrating the AA' section of FIG. 6 according to one embodiment.

[0114] Referring to FIG. 7A, the button member (420-1) and the hook member (420-2) may be coupled to each other within the common portion of the housing (410). In this case, for example, a first spring (471-1) may be disposed between the button member (420-1) and the hook member (420-2). The first spring (471-1) may be disposed within a groove (420-5) (e.g., a spring groove) formed in the button member (420-1) and open toward the front. The first spring (471-1) provides an opposite force between the button member (420-1) and the hook member (420-2) along the thickness direction, so that the button member (420-1) and the hook member (420-2) may be biased away from each other.

[0115] Additionally, for example, second springs (472-1, 472-2) may be disposed between the hook member (420-2) and the housing (410). The second springs (472-1, 472-2) may be disposed within grooves (420-7, 420-8) formed in the button member (420-1). These grooves may be open in the forward direction. The second springs (472-1, 472-2) provide opposing forces between the housing (410) and the hook member (420-2) along the thickness direction, so that the housing (410) and the hook member (420-2) may be biased away from each other.

[0116] Accordingly, for example, when the button member (420-1) is pressed by an external force from the user, a repulsive force due to the elastic forces of the first spring (471-1) and the second springs (472-1, 472-2) can be applied to the user.

[0117] According to one embodiment, when the first spring (471-1) and the second springs (472-1, 472-2) are arranged in two stages, the phenomenon of the strap (450) being detached from the housing (410) due to the button member (420-1) being unintentionally pressed can be prevented. In addition, even when the button member (420-1) is pressed to a certain extent, the phenomenon of the hook member (420-2) moving immediately can be prevented because the first spring (471-1) absorbs a certain section of force.

[0118] FIG. 7b is a cross-sectional view illustrating the AA' section of FIG. 6 according to one embodiment.

[0119] Referring to Fig. 7b, for example, the first spring (471-1) may be omitted. For example, the button member (420-1) and the hook member (420-2) may be coupled to each other without the first spring (471-1). In addition, when a user presses the button member (420-1), a repulsive force due to the elastic forces of the second springs (472-1, 472-2) may be applied to the user.

[0120] Accordingly, when the strap (450) is mounted on the housing (410), the phenomenon of the strap (450) tilting with respect to the housing (410) can be prevented by at least one of the first spring (471-1) or the second springs (472-1, 472-2).

[0121] Figures 7c to 7f are drawings showing examples of a fastening member being assembled to a housing according to one embodiment. Figure 7f is an enlarged view of area A in Figure 7e.

[0122] Referring to FIGS. 7C to 7F, the fastening member (420) can be fixed to the housing (410) without a separate bracket (430). According to one embodiment, the fastening member (420) inserted into the opening (414) can be fixed to the housing (410) by a plurality of fastening holes (433-1, 433-2) inserted into the thickness portion of the housing so as to cover a portion of the periphery of the main body of the opening (414) and a portion of the edge of the fastening member (420). For example, in the button portion of the fastening member (420) (e.g., the button portion (420-1)), the ends (420-9, 420-8) of the outer edge adjacent to the opening can be formed to have a lower height along the thickness direction than other portions of the edge of the button portion of the fastening member (420). These end portions can have a step shape.

[0123] Additionally, recessed portions (410-7, 410-8) may be formed in a groove shape around the opening (414) of the housing (410) at positions adjacent to the ends (420-9, 420-8) of the fastening member (420). Additionally, a plurality of fastening holes (433-1, 433-2) may be press-fitted into the housing (410) so as to cover the ends (420-9, 420-8) of the fastening member (420) and the recessed portions (410-7, 410-8) of the housing (410). Accordingly, the fastening member (420) may be stably fixed to the housing (410) without using the bracket (430). Since the edges of the fasteners (433-1, 433-2) overlap with the step-shaped portion at the end of the button member (420-1), the fasteners (433-1, 433-2) can restrict or limit the movement in the rearward direction in the thickness direction of the button member (420-1).

[0124] FIG. 8a is a drawing for explaining a plate spring disposed between a fastening member and a common portion according to one embodiment.

[0125] FIG. 8b is a drawing for explaining a plate spring disposed between a fastening member and a common portion according to one embodiment.

[0126] Referring to FIGS. 8A and 8B, the plate spring (473) may extend from the hook member (420-2) in the hollow portion of the housing (410) and be positioned below the hook member (420-2). Accordingly, when a user presses the button member (420-1), the spring (473) may be pressed against the housing (410), and a repulsive force due to the elasticity of the plate spring (473) may be applied to the user.

[0127] FIG. 9 is a cross-sectional view illustrating a BB' section of FIG. 6 according to one embodiment.

[0128] Referring to FIG. 9, the hook member (420-2) can be disposed within the hollow portion (412) of the housing (410). The hook member (420-2) can be disposed within the mounting portion (412-9) within the hollow portion (412) of the housing (410). The hook member (420-2) includes a groove (420-7) formed (e.g., open) toward the front (e.g., +z direction) of the electronic device (400), and a second spring (472-1) can be disposed within the groove (420-7). The second spring (472-1) is arranged between the anchoring portion (412-9) and the hook member (420-2) within the common portion (412), so that it can exert an elastic force from the housing (410) toward the hook member (420-2), i.e., away from the surface of the housing (410) that provides the bottom of the anchoring portion (412-9).

[0129] According to one embodiment, the width (L1) as the total width (or maximum width) of the hook member (420-2) in the width direction (e.g., in the direction perpendicular to the -z direction, such as the direction along the x direction) may be greater than the width (D1) as the total width of the first opening (410-1) formed toward the rear (e.g., in the -z direction) of the electronic device (400). According to one embodiment, the length (L2) as the total length of the hook member (420-2) in the length direction (e.g., in the direction along the thickness direction, such as the -z direction) may be smaller than the width (D2) as the total width of the second opening (410-2) formed toward the side (e.g., in the direction perpendicular to the -z direction) of the electronic device (400).

[0130] In one embodiment, the fixing portion (412-9) and the first opening (410-1) may overlap each other along the z-direction to provide a space in which the button member (420-1) and / or the hook member (420-2) of the fastening member (420) can move, and the fastening member (420) can reciprocate along the path. The second opening (410-2) may provide a space in which the fastening portion (10) of the fastening member (420) that moves together with the button member (420-1) and / or the hook member (420-2) can move.

[0131] According to one embodiment, the hook member (420-2) includes a fastening portion (10), and an ending portion of the fastening portion (10) can protrude toward the front (e.g., +z direction) or rear (e.g., -z direction) of the electronic device.

[0132] Here, the end (e.g., the tip) of the binding portion (10) may be positioned inside the outermost surface of the housing (410) in which the second opening (410-2) is formed. The binding portion (10) may include a protruding portion extending in the -z direction at a common thickness (e.g., a position where line L1 is defined), thereby forming a step or a hook at the end of the binding portion.

[0133] FIGS. 10A and 10B are drawings showing a protruding attachment portion from a strap adapter of a strap according to one embodiment.

[0134] Referring to FIGS. 10A and 10B , a strap adapter (451) included in a strap (450) according to one embodiment may include a fastening portion (452). For example, the fastening portion (452) may be formed to protrude from one side of the strap adapter (451) at a central portion of the strap adapter (451). For example, referring again to FIG. 4 , the fastening portion (452) may further protrude from the strap adapter (451) in the -x direction. The fastening portion (452) of the strap adapter (451) may be formed with a hooking structure so as to be fastened to a hook member (420-2) disposed in a hollow portion (e.g., 412) of a housing (e.g., 410).

[0135] FIG. 10c is a drawing showing a fastening portion that does not protrude from a strap adapter of a strap according to one embodiment.

[0136] Referring to FIG. 10c, a strap adapter (451) included in a strap (450) according to one embodiment may include a fastening portion (452). For example, the fastening portion (452) may be formed so as not to protrude from one side of the strap adapter (451) at a central portion of the strap adapter (451). For example, referring again to FIG. 4, the fastening portion (452) may not protrude further from the strap adapter (451) along the -x direction (i.e., in the plane direction of the xy plane). The fastening portion (452) of the strap adapter (451) may be formed with a hooking structure so as to be fastened with a hook member (420-2) disposed in a hollow portion (e.g., 412) of a housing (e.g., 410).

[0137] The protrusion distance of the hook member (420-2) in the +x direction may vary depending on the protrusion distance of the fastening portion (452) in the -x direction and toward the common portion of the electronic device (400). In one embodiment, the extent to which the hook member (420-2) protrudes toward the side of the electronic device (400) when the fastening portion (452) does not protrude from the strap adapter (451) (e.g., based on the outermost surface of the housing (410)) may be greater than the extent to which the hook member (420-2) protrudes toward the side of the electronic device (400) when the fastening portion (452) protrudes from the strap adapter (451). Accordingly, when the fastening portion (452) does not protrude from the strap adapter (451) (or when the fastening portion (452) protrudes only slightly), the strap (450) can be effectively fastened to the housing (410) without deteriorating the quality of the exterior appearance of the strap (450) of the electronic device (400) and while increasing the design perfection of the exterior appearance.

[0138] FIG. 10d is a drawing for explaining an example of a fastening portion and a protruding guide formed on a strap according to one embodiment.

[0139] Referring to FIG. 10D, a strap (450) according to one embodiment may include a fastening portion (452) and protruding guides (453-1, 453-2). For example, one end of the strap body (455) along the direction closest to the electronic device (400) may be formed in a shape corresponding to the shape or cross-section of a hollow portion (e.g., 412) of a housing (410), and the fastening portion (452) may be arranged at a central portion (e.g., with respect to the center along the y direction) of one end of the strap body (455). For example, the protruding guides (453-1, 453-2) may be formed in a shape corresponding to recesses (e.g., 412-1, 412-2) formed in a hollow portion (e.g., 412) of a housing (e.g., 410), and may be arranged at both ends of one end of the strap body (455), respectively. For example, the fastening portion (452) and the protruding guides (453-1, 453-2) can perform the function of a strap adapter (e.g., 451).

[0140] FIGS. 11A and 11B are drawings showing examples of a hook member being fastened to a fastening portion of a strap according to one embodiment.

[0141] Referring to FIGS. 11A and 11B, for example, the fastening portion (10) of the hook member (420-2) coupled to the button member (420-1) and movable together may include a hooking structure formed to face one direction when the strap (450) is fastened to the housing (410). The fastening portion (452) formed on the strap (450) may include a hooking structure formed to face a direction opposite to the one direction in which the hooking structure of the fastening member (420) extends. Accordingly, the hooking structure of the fastening portion (10) of the hook member (420-2) coupled to the button member (420-1) may be fastened to the strap (450) at the hooking structure of the fastening portion (452) formed on the strap (450).

[0142] Referring to FIG. 11B, the fastening member (420) (indicated by the fastening portion (10)) may face the strap (450) along the x-direction, which is the coupling direction of the electronic device (400) (e.g., an arrow in FIG. 11B). In a detachable coupling of the electronic device (400) and the strap (450), the fastening portion (10) may face the fastening portion (452) and engage with each other to prevent the housing (410) and the strap (450) from being separated from each other. The housing (410) and the strap (450) may be coupled in a detachable manner by coupling the fastening portion (10) with the fastening portion (452), but is not limited thereto.

[0143] FIG. 12A is a drawing showing the arrangement of button members when looking at the electronic device from the rear of the electronic device according to one embodiment.

[0144] FIG. 12b is a cross-sectional view illustrating the CC' section of FIG. 12a according to one embodiment.

[0145] Referring to FIGS. 12A and 12B, a strap (450) according to one embodiment may be attached to a housing (410). According to one embodiment, a button member (420-1) may be coupled with a hook member (420-2) and disposed in a hollow portion (412) of the housing (410) so as to be exposed to the outside of the housing (410) by the hollow portion (412). The hook member (420-2) may be disposed in a seating portion (412-9) within the hollow portion (412). Additionally, a second spring (472-1) may be disposed between the hook member (420-2) and the seating portion (412-9) within the hollow portion (412).

[0146] According to one embodiment, the opening (414) of the housing (410) may be formed to have a stepped cross-section. For example, the opening (414) may include a first support portion (414-1) as a first support surface and a second support portion (414-2) as a second support surface. Accordingly, when the button member (420-1) is introduced into the opening (414) and moves toward the hollow portion (412) in the +z direction, the protruding portion (40) surrounding the button member (420-1) may be supported by the second support portion (414-2). The second support surface may restrict further movement of the button member (420-1) toward the seating portion (412-9).

[0147] According to one embodiment, the bracket (430) may be secured on the first support portion (414-1) of the opening (414) while surrounding the button member (420-1). Accordingly, when the button member (420-1) moves in the -z direction toward the outside of the electronic device (400) through the opening (414), the bracket (430) secured to the opening (414) may prevent the button member (420-1) from being detached from the housing (410) and extending to the outside of the electronic device (400) through the opening (414) by blocking the movement of the protruding portion (40) surrounding the button member (420-1).

[0148] According to one embodiment, the fastening portion (10) of the hook member (420-2) may include a hooking structure that protrudes toward the rear (e.g., -z direction) of the electronic device (400). The hooking structure of the fastening portion (10) of the hook member (420-2) may be formed by the protruding portion (10-1) of the fastening portion (10). In addition, the hook member (420-2) may include a recessed portion (10-2) formed by the protrusion of the protruding portion (10-1).

[0149] Additionally, the fastening portion (452) of the strap (450) may include a hooking structure that faces the front (e.g., +z direction) of the electronic device (400) when the strap (450) is fastened to the housing (410). The hooking structure of the fastening portion (452) of the strap (450) may be formed by a protruding portion (452-1) of the fastening portion (452) of the strap (450). Additionally, the fastening portion (452) of the strap (450) may include a recessed portion (452-2) formed by the protrusion of the protruding portion (452-1).

[0150] According to one embodiment, the strap (450) can be fastened to the housing (410) by interlocking the hook structure of the fastening portion (10) of the hook member (420-2) of the housing (410) with the fastening structure of the fastening portion (452) of the strap (450). When the strap (450) is fastened to the housing (410), the fastening portion (452) of the strap (450) can be formed to receive at least a portion of the fastening portion (10) of the hook member (420-2) of the housing (410). For example, the protruding portion (10-1) of the hook member (420-2) can be received in the recessed portion (452-2) of the fastening portion (452) of the strap (450). Additionally, for example, the protruding portion (452-1) of the fastening portion (452) of the strap (450) can be accommodated in the recessed portion (10-2) of the hook member (420-2). The strap (450) detachably attached to the housing (410) includes protruding portions (10-1 and 452-1) that overlap each other along the coupling direction (e.g., x-direction).

[0151] Referring to FIG. 12b, since the spring (472-1) biases the fastening member (420) in a rearward direction (e.g., in the -z direction), the strap (450) can be detachably attached to the housing (410) by the force of one or more springs between the fastening member (420) and the housing (410).

[0153] FIG. 13b is a cross-sectional view showing the D-D' section of FIG. 13a according to one embodiment.

[0154] Referring to FIGS. 13A and 13B , a strap (450) according to one embodiment may be attached to a housing (410). For example, a first protruding guide (453-1) included in a strap adapter (451) may be inserted into a second recess (412-2) of a hollow portion (412) of the housing (410), and a second protruding guide (453-2) included in the strap adapter (451) may be inserted into a second recess (412-2) of a hollow portion (412) of the housing (410). Accordingly, the first recess (412-1) and the second recess (412-2) may prevent the first protruding guide (453-1) and the second protruding guide (453-2) of the strap adapter (451) from moving in a lateral direction of the electronic device (400), such as along the y-direction. For example, the first recess (412-1) and the second recess (412-2) can prevent the strap adapter (451) from moving in a direction perpendicular to the direction in which the strap adapter (451) moves into the hollow portion (412) of the housing (410) to be fixed to the housing (410).

[0155] FIG. 14a is a drawing for explaining a recess formed in a strap according to one embodiment.

[0156] FIG. 14b is a drawing for explaining a hollow portion in which a protruding guide is formed according to one embodiment.

[0157] FIG. 14c is a cross-sectional view showing the E-E' section of FIG. 14b according to one embodiment.

[0158] Referring to FIGS. 14a to 14c, protruding guides (412-5, 412-6) formed in the hollow portion (412) of the housing (410) can be inserted into recesses (456-1, 456-2) of the strap adapter (451).

[0159] Referring to FIG. 14A, a strap adapter (451) according to one embodiment may include a third recess (456-1) and a fourth recess (456-2). In addition, a fastening portion (452) may be formed in a central portion of the strap adapter (451). For example, in the strap adapter (451), the fastening portion (452) may be formed between the third recess (456-1) and the fourth recess (456-2).

[0160] Referring to FIG. 14B, the hollow portion (412) of the housing (410) according to one embodiment may include a third protruding guide (412-5) and a fourth protruding guide (412-6). In addition, a hook member (420-2) may be disposed in the central portion of the hollow portion (412) of the housing (410). For example, the hook member (420-2) may be disposed between the third protruding guide (412-5) and the fourth protruding guide (412-6) in the hollow portion (412) of the housing (410).

[0161] Referring to FIG. 14c, the fastening portion (452) of the strap adapter (451) according to one embodiment can be fastened to the hook member (420-2) arranged in the hollow portion (412) of the housing (410). For example, the third protruding guide (412-5) and the fourth protruding guide (412-6) formed in the hollow portion (412) of the housing (410) can be inserted into the third recess (456-1) and the fourth recess (456-2) formed in the strap adapter (451).

[0162] Accordingly, the third recess (456-1) and the fourth recess (456-2) can prevent the third protruding guide (412-5) and the fourth protruding guide (412-6) from moving in the lateral direction of the electronic device (400). For example, the third recess (456-1) and the fourth recess (456-2) can prevent the strap adapter (451) from moving in a direction perpendicular to the direction in which the strap adapter (451) moves toward the hollow portion (412) of the housing (410) to be fastened to the housing (410).

[0163] FIG. 15a is a drawing showing a protrusion formed on a strap according to one embodiment.

[0164] FIG. 15b is a cross-sectional view showing a portion of the F-F' section of FIG. 15a, with the strap attached to the housing according to one embodiment.

[0165] Referring to FIGS. 15A and 15B, protrusions (e.g., 51, 52, 53, 54, 55, 56) formed on a strap (450) according to one embodiment can compensate for a tolerance between the strap (450) and the housing (410) when the strap (450) is fastened to the housing (410) and prevent the strap (450) from flowing or moving unintentionally within the housing (410).

[0166] Referring to FIG. 15A, protrusions (51, 52) may be formed on a surface facing the housing (410) at one end of the strap (450) according to one embodiment. For example, among the surfaces facing the housing (410) at one end of the strap (450), a first protrusion (51) may be formed between a second protrusion guide (453-2) and a fastening portion (452), and a second protrusion (52) may be formed between a first protrusion guide (453-1) and a fastening portion (452).

[0167] According to one embodiment, protrusions (53, 54, 55, 56) may be formed at the edge portion of one end of the strap (450). For example, a third protrusion (53) and a fourth protrusion (54) may be formed at the edge portion that is bent on the side facing the housing (410) of one end of the strap (450) with the fastening portion (452) therebetween. For example, a fifth protrusion (55) and a sixth protrusion (56) may be formed at the edge portion that is bent on the side facing the housing (410) of one end of the strap (450) with the fastening portion (452) therebetween.

[0168] According to one embodiment, the first protrusion (51), the third protrusion (53), and the fifth protrusion (55) may be arranged to at least partially overlap each other. According to one embodiment, the second protrusion (52), the fourth protrusion (54), and the sixth protrusion (56) may be arranged to at least partially overlap each other.

[0169] Referring to FIG. 15B, according to one embodiment, when the strap (450) is fastened to the housing (410), the second protrusion (52) can be pressed against the side wall (412-1) of the hollow portion (412) of the housing (410). According to one embodiment, the second protrusion (52) can be formed of a material having elasticity. According to one embodiment, when the strap (450) is fastened to the housing (410), the second protrusion (52) can exert an elastic force toward the side wall (412-1) of the hollow portion (412), thereby compensating for the tolerance (61) or gap between the side wall (412-1) of the hollow portion (412) and the strap (450). In addition, the strap (450) can be prevented from flowing within the housing (410).

[0170] In one embodiment, when the strap (450) is attached to the housing (410), the fourth protrusion (54) may be formed to partially overlap with a wall (63) extending from a portion of the side wall (412-1) of the hollow portion (412) of the housing (410) closer to the rear of the electronic device (400). In addition, in one embodiment, when the strap (450) is attached to the housing (410), the sixth protrusion (56) may be formed to partially overlap with a wall (65) extending from a portion of the side wall (412-1) of the hollow portion (412) of the housing (410) closer to the front of the electronic device (400). Here, the walls (412-1, 63, and 65) may contribute to defining the hollow portion of the housing (410). In one embodiment, the fourth protrusion (54) and the sixth protrusion (56) may be formed of a material having elasticity. Accordingly, the fourth protrusion (54) and the sixth protrusion (56) can compensate for a tolerance or gap between an edge portion of one end of the strap (450) and the walls (63, 65) of the hollow portion (412) of the housing (410) when the strap (450) is fastened to the housing (410). In addition, the strap (450) can be prevented from flowing within the housing (410). Here, the tolerance or gap can be defined between facing surfaces of the housing (410) and the strap (450), which can include an inner surface of the housing (410) defining the hollow portion and an outer surface of the strap (450) facing the inner surface of the housing (410).

[0171] In one embodiment, the degree to which the fourth protrusion (54) partially overlaps with the wall (63) of the cavity portion (412) may be greater than the degree to which the sixth protrusion (56) overlaps with the wall (65) of the cavity portion (412). Accordingly, when the strap (450) is fastened to the housing (410), the hook member (420-2) can be more stably fastened to the fastening portion (452).

[0209] Referring to FIG. 27a, in a state where a fastening member (520) is placed within a housing (410) according to one embodiment, a fastening portion (452) of a strap (450) can be introduced into the interior of the housing (410) by moving toward the fastening member (520).

[0210] Referring to FIG. 27b, the inclined surface (92) of the hook structure of the fastening member (520) disposed within the housing (410) according to one embodiment and the inclined surface (90) of the fastening portion (452) of the strap (450) can contact each other. The inclined surface (90) of the fastening portion (452) of the strap (450) can apply force to the inclined surface (92) of the hook structure of the hook portion (524) of the fastening member (520) disposed within the housing (410), and the fastening member (520) can move toward the front (e.g., in the +z direction) of the electronic device (400) by the force applied to the inclined surface (92). For example, the inclined surface (90) can cause the fastening member (520) to move toward the front (e.g., +z direction) of the electronic device (400) and compress the spring (62) by applying a force greater than the elastic force of the spring (62) to the inclined surface (92).

[0211] Referring to FIG. 27c, as the fastening portion (452) of the strap (450) according to one embodiment is pulled further into the housing (410), the fastening portion (452) of the strap (450) may be fastened to the hook portion (524) of the fastening member (520) disposed within the housing (410). Here, when the inclined surface (90) formed on the fastening portion (452) of the strap (450) moves deeper into the hollow portion than the inclined surface (92) formed on the fastening structure of the hook portion (524) of the fastening member (520) disposed within the housing (410), since the inclined surface (90) exerts a force smaller than the elastic force of the spring (62), the fastening member (520) may move in the rearward direction (e.g., -z direction) of the electronic device (400) by the biasing force applied from the spring (62). When the fastening member (520) moves in the rearward direction (e.g., -z direction) of the electronic device (400), the spring (62) becomes uncompressed, and the two hooks forming each of the inclined surfaces (90) and the inclined surfaces (92) can overlap each other in the x direction.

[0212] FIGS. 28a and 28b are drawings illustrating air pockets formed in a strap according to one embodiment.

[0213] Referring to FIG. 28a, according to one embodiment, an air pocket (459) may be formed at a location adjacent to a strap adapter (451) in a strap body (455) of a strap (450). The air pocket (459) may be formed along the strap adapter (451) at a location adjacent to the strap adapter (451) in the strap body (455).

[0214] Figure 28b is a cross-sectional view showing the H-H' section of Figure 28a.

[0215] Referring to FIG. 28b, according to one embodiment, the air pocket (459) may be formed in a sunken structure. The thickness of the portion of the strap body (455) where the air pocket (459) is formed may be smaller than the thickness of other portions. The air pocket (459) may be an empty space or an empty gap.

[0216] For example, an air pocket (459) can be formed in a portion of the strap body (455) where the bending is greater than a preset value to increase the flexibility of the strap (450), and when a user wears an electronic device on a body such as the body, the strap (450) can be made to adhere closely to the body.

[0217] FIGS. 29A to 29C are drawings for explaining the protrusion of the rear plate and the biometric sensor module disposed on the rear of the electronic device.

[0218] FIGS. 29A, 29B, and 29C are drawings illustrating a rear plate and a biometric sensor module disposed on the rear surface of an electronic device according to one embodiment. FIG. 29D is a drawing illustrating a curvature of a first portion of the rear plate of the electronic device according to one embodiment. FIGS. 29E and 29F are drawings for explaining a rear plate protruding at a predetermined curvature from the rear surface of the electronic device according to one embodiment.

[0219] Referring to FIGS. 29A, 29B, and 29C, a rear plate (460) and a biosensor module (411) may be disposed on the rear surface of an electronic device (400) according to one embodiment. According to one embodiment, the biosensor module (411) may include light emitting diodes (LEDs) and photodiodes (PDs) for obtaining biometric information of a user. For example, the biosensor module (411) may include LEDs and / or PDs for at least one of heart rate (HR) measurement, irregular heart rhythm notification (IHRN) measurement, electrocardiogram (ECG) measurement, blood pressure (BP) measurement, bioelectrical impedance analysis (BIA) measurement, or percutaneous oxygen saturation (SpO2) measurement. In addition, for example, the biosensor module (411) may include LEDs and / or PDs for measuring at least one of antioxidant levels or advanced glycation end products.

[0220] For example, the LEDs may include 13 LEDs. For example, the LEDs may include 3 Green LEDs, 3 IR LEDs, 2 Red LEDs, 2 UV LEDs, 2 Yellow LEDs, 1 Blue1 LED, and 1 Blue2 LED. However, the types and numbers of LEDs included in the LEDs are not limited thereto.

[0221] For example, PDs may include four PDs. For example, PDs may include two normal PDs and two green PDs. However, the types and number of PDs included in PDs are not limited thereto.

[0222] According to one embodiment, the biosensor module (411) may be placed on a PCB. In this case, for example, the PCB may be formed with a six-layer structure and may have a thickness of approximately 0.38T. In addition, for example, the PCB may include an electrically erasable programmable read-only memory (EEPROM) and may support calibration for light intensity.

[0223] According to one embodiment, the back plate (460) may include a first portion (460-1) and a second portion (460-2). According to one embodiment, the first portion (460-1) of the back plate (460) may be positioned at a position corresponding to the biometric sensor module (411), and at least some of the plurality of LEDs and the plurality of PDs included in the biometric sensor module (411) may be visible from the outside of the electronic device (400) through the first portion (460-1) of the back plate (460). For example, the first portion (460-1) of the back plate (460) may be implemented as glass, but is not limited thereto.

[0224] According to one embodiment, the second portion (460-2) of the back plate (460) may be positioned to surround the edge of the first portion (460-1) of the back plate (460). In FIGS. 29A to 29F , the back plate (460) is described as having the first portion (460-1) and the second portion (460-2) as separate components, but is not limited thereto. The back plate (460) may also be formed integrally with the first portion (460-1) and the second portion (460-2) as one component.

[0225] Referring to FIGS. 29d and 29f, the rear plate (460) of the electronic device (400) according to one embodiment may be formed such that the first portion (460-1) has a predetermined curvature. The rear plate (460) of the electronic device (400) may be formed such that the first portion (460-1) protrudes more toward the rear of the electronic device (400) than the second portion (460-2) of the rear plate (460). For example, the rear plate (460) may be formed to have a curvature range of approximately 45R to 65R, and preferably may have a curvature of approximately 50R. In addition, for example, the rear plate (460) may protrude toward the rear of the electronic device (400) by an amount of approximately 1.5 mm to 3.5 mm, and preferably by an amount of approximately 2.5 mm.

[0226] FIG. 29g is a drawing showing an example of securing the adhesion force applied to the body by the electronic device and the stability of the electronic device by the back plate of the electronic device having a curvature according to one embodiment.

[0227] Referring to FIG. 29g, when the curvature of the rear plate (460) of the electronic device (400) according to one embodiment is 50R, the electronic device (400) can be pressed against the user's body with a force of, for example, approximately 1.5 to 2.0 N, and accordingly, the electronic device (400) can be stably worn on the user's body without causing discomfort (e.g., pain, pressure) due to skin pressure to the user.

[0228] In the case where the curvature of the rear plate (460) of the electronic device (400) according to one embodiment is 50R, for example, it can have a relative displacement change of approximately 0.6 to 0.7 mm in the Y direction, and accordingly, the electronic device (400) can be more stably worn on the user's body, and the electronic device (400) can stably perform a sensing operation to obtain biometric information.

[0229] FIG. 29h is a diagram illustrating the deviation of biosignals measured multiple times by an electronic device including a back plate having a curvature according to one embodiment.

[0230] Referring to FIG. 29h, when the curvature of the rear plate (460) of the electronic device (400) is approximately 50R, a biosignal (e.g., heart rate change) captured multiple times may have a relatively small deviation. For example, when the curvature of the rear plate (460) of the electronic device (400) is approximately 50R, the mean average error (MAE) may be approximately 1.84bpm, which is a lower value than when the curvature is approximately 114R. In addition, for example, when the curvature of the rear plate (460) of the electronic device (400) is 50R, the standard deviation may be approximately 1.10bpm, which is a lower value than when the curvature is approximately 114R. In addition, for example, when the curvature of the rear plate (460) of the electronic device (400) is approximately 50R, the pass rate can be approximately 97.6%, which is a higher value than when the curvature is approximately 114R. Accordingly, when a biosignal is measured by an electronic device including a rear plate having a curvature, the biosignal can be measured more stably.

[0231] According to one embodiment, the rear plate (460) reduces the radius of curvature (R) of the first portion (460-1), so that when the electronic device (400) is worn on the user's body, sufficient adhesion can be provided between the electronic device (400) and the user's body. For example, when a strap of the electronic device is fastened to the electronic device without a lug, the electronic device may not provide sufficient adhesion to the user's body compared to when the strap is fastened by a lug of the housing. However, according to one embodiment, the electronic device (400) includes a rear plate (460) having a predetermined curvature, so that even when the strap (450) is positioned further outward than the housing (410), the electronic device (400) can provide sufficient adhesion to the user's body without causing discomfort to the user.

[0232] Additionally, for example, due to the protrusion of the first part (460-1) of the rear plate (460), the first part (460-1) of the rear plate (460) can be further penetrated into and adhered to the user's skin. Accordingly, the empty space between the LEDs and PDs of the biosensor module (411) and the user's body can be eliminated, and the accuracy of biosignal measurement by the electronic device (400) can be increased.

Each of the external electronic devices (2902 or 404) may be the same or a different type of device as the electronic device (2901). According to one embodiment, all or part of the operations executed in the electronic device (2901) may be executed in one or more of the external electronic devices (2902, 404, or 408). For example, when the electronic device (2901) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (2901) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or additional functions or services related to the request, and transmit the results of the execution to the electronic device (2901). The electronic device (2901) may process the results as is or additionally and provide them as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technologies may be utilized, for example. The electronic device (2901) may provide ultra-low latency services using, for example, distributed computing or mobile edge computing. In one embodiment, the external electronic device (2904) may include an Internet of Things (IoT) device. The server (2908) may be an intelligent server utilizing machine learning and / or a neural network.According to one embodiment, an external electronic device (2904) or server (2908) may be included within the second network (2999).
