An outer side of the front bezel 123a may have a shape, a thickness of which gradually decreases as it goes from an upper side to a lower side.

A second seating part 121b and a rear bezel 123b may be disposed on a lower side (e.g., the -z axis) of the housing body <NUM>. The second seating part 121b may be formed to be flat at a lower end of the housing body <NUM> in the -z axis direction. According to an embodiment, at least a portion of the second seating part 121b and at least a portion of the housing body <NUM> may be disposed to be perpendicular to each other. The second seating part 121b may have a band shape, and at least a portion of an outskirt of the rear cover <NUM> may be seated thereon. The bonding member may be disposed at at least a portion between the second seating part 121b and the rear cover <NUM>. The second seating part 121b may be formed to be symmetrical to the first seating part 121a in the z axis direction with respect to the xy plane at a center point of the housing body <NUM>. The rear bezel 123b may be disposed to surround at least a portion of an outskirt of the second seating part 121b. The rear bezel 123b may have a band shape along the band-shaped second seating part 121b similarly to the front bezel 123a. The rear bezel 123b may be formed to be symmetrical to the front bezel 123a in the z axis direction with respect to the xy plane at the center point of the housing body <NUM>.

At least one strap connecting structure 120a may be formed on one side of the outskirt of the housing body <NUM>. According to an embodiment, at least a portion of the strap connecting structure 120a may include a recess shape that is recessed inwards from the outskirt of the housing body <NUM> by a specific depth. According to various embodiments, the strap connecting structure 120a may include an opening <NUM> (e.g., a recess part or a hole) of a specific depth formed at the outskirt of the housing body <NUM>, and a first holding recess 127a and a second holding recess 127b that extend to the opening <NUM> with respect to the xy plane at the center point of the housing body <NUM>, and is formed in an inward direction of the housing body <NUM> while having an inclination angle that is larger or smaller than <NUM> degrees in the z axis direction and the - z axis direction.

According to various embodiments, the first holding recess 127a may be disposed in a first diagonal direction (or a direction of a specific angle between an inward direction and a vertical direction) between an inward direction of the housing body <NUM> from the opening <NUM> and a vertical direction (e.g., among the vertical directions, an upward vertical direction or the z axis direction) corresponding to the z axis direction from the center of the housing body <NUM>, with respect to a horizontal direction (or when the center of the ring shape housing body <NUM> is positioned on a flat surface to face an upper side, a direction that crosses the flat surface or a direction that is parallel to the flat surface). The second holding recess 127b may be disposed in a second diagonal direction between an inward direction of the housing body <NUM> from the opening <NUM> and a vertical direction (or, among the vertical directions, a downward vertical direction or the -z axis direction) with respect to the horizontal direction. The first diagonal direction and the second diagonal direction may be disposed to be symmetrical to each other upwards and downwards (or in a vertical direction) with respect to the horizontal direction.

The first holding recess 127a may include a first inclined surface 126a having an inclination angle (e.g., an angle between <NUM> degrees to <NUM> degrees) that is larger than a reference angle of <NUM> degrees in the z axis direction, in an inward direction, from the center point of the housing body <NUM>, and a first holding hangover portion 124a (or a first holding hangover structure, or a boss or protrusion having a hangover shape) that defines the opening <NUM> (e.g., a recess), is spaced apart from the first inclined surface 126a by a specific interval, and protrudes in an opposite direction to the front bezel 123a. A shortest spacing distance between the first inclined surface 126a and the first holding hangover portion 124a may correspond to a thickness of the holding part of the inserted strap. The first inclined surface 126a may be disposed to be closer to the center of the housing body <NUM> than the first holding hangover portion 124a. A length of the first holding hangover portion 124a may be shorter than a length of the first inclined surface 126a. Cross-sectional shapes of the first inclined surface 126a and the first holding hangover portion 124a may have a hook shape. The opening <NUM> may be classified into a recess or a hole (opening) according to an observation direction. For example, when viewed from a lateral side of the housing body <NUM>, the opening <NUM> may be classified into a recess, and may be classified into a hole from a lateral side of the holding hangover portions 124a and 124b.

The second holding recess 127b, for example, may include a second inclined surface 126b having an inclination angle (e.g., an angle between <NUM> degrees and <NUM> degrees) that is smaller than -<NUM> degrees with respect to the -z axis direction inwards from the center point of the housing body <NUM>, and a second holding hangover portion 124b (or a hangover structure or a boss or a protrusion having a hangover shape) that defines the opening <NUM>, is spaced apart from the second inclined surface 126b by a specific interval, and protrudes in an opposite direction to the rear bezel 123b. A shortest spacing distance between the second inclined surface 126b and the second holding hangover portion 124b may correspond to a thickness of the holding part of the inserted strap. The second holding recess 127b, for example, may be formed to be symmetrical to each other upwards with respect to the center point of the housing body <NUM>. The second inclined surface 126b may be formed to be symmetrical to each other upwards and downwards with respect to the center point of the housing body <NUM>. The second inclined surface 126b may be disposed to be closer to the center of the housing body <NUM> than the second holding hangover portion 124b. A length of the second holding hangover portion 124b may be shorter than a length of the second inclined surface 126b. According to various embodiments, a protruding length of the second holding hangover portion 124b may be the same as a protruding length of the first holding hangover portion 124a. The cross-sectional shapes of the second inclined surface 126b and the second holding hangover portion 124b may be the same as or similar to the cross-sectional shapes of the first inclined surface 126a and the first holding hangover portion 124a.

According to various embodiments, the first inclined surface 126a and the second inclined surface 126b may be formed in a partial area of the strap connecting structure 120a. For example, the strap connecting structure 120a may be formed on an outer surface of the housing body <NUM>, and a length of the recess in a direction of the xy plane may be larger than a height of the recess in the z axis direction or the -z axis direction. A lower end (e.g., a periphery in the -z axis direction or a portion of a peripheral end in the -z axis direction) of the first inclined surface 126a and an upper end (e.g., a periphery in the z axis direction or a portion of a peripheral end in the z axis direction) of the second inclined surface 126b may be connected to each other.

The opening <NUM>, the first inclined surface 126a, and the second inclined surface 126b, which have been described above, may be formed at a central portion of the strap connecting structure 120a, and recesses having a specific depth may be provided on opposite sides of the strap connecting structure 120a to be stepped. The stepped recesses may define strap contacting areas 120a_1 and 120a_2, which wing parts formed in the straps <NUM> and <NUM> contact.

Central portions (e.g., the first holding part and the second holding part, which will be described above) of the straps <NUM> and <NUM> may be coupled to a central portion (e.g., an area, in which the first inclined surface 126a and the second inclined surface 126b are formed, or an area, in which the first holding recess 127a and the second holding recess 127b are formed) of the strap connecting structure 120a, and wing parts of the straps <NUM> and <NUM> may be coupled to opposite sides of the strap connecting structure 120a to be coupled thereto. In the regard, a first wing seating part 120a_1 and a second wing seating part 120a_2 having a specific depth may be formed on opposite sides of portions of the strap connecting structure 120a, to which a first holding part <NUM> and a second holding part <NUM> of the first strap <NUM> are coupled. According to various embodiments, a protruding structure, such as a hook, or a recessed structure may be formed in the first holding recess 127a and the second holding recess 127b to increase a coupling force with the strap. The protruding structure, for example, may include a structure that protrudes from an inside (e.g., a periphery between the -x axis and the -z axis) of the first holding hangover portion 124a in an inward direction (e.g., a direction between the -x axis and the -z axis) of the housing <NUM>. The recessed structure, for example, may include a structure that is recessed from an inner surface (e.g., a periphery between the -x axis and the -z axis) of the first holding hangover portion 124a in an outward direction (e.g., a direction between the -x axis and the z axis) of the housing <NUM>. The protruding structure or the recessed structure also may be formed in the second holding hangover portion 124b in the same way. When the above-described protruding structure or recessed structure is formed in the first holding recess 127a and the second holding recess 127b, a shape (a shape of the holding parts <NUM> and <NUM> disposed in the strap coupling parts 139a and 139b) of the straps inserted into the housing <NUM> may have a shape corresponding to the protruding structure or the recessed structure. For example, the shapes (e.g., parts inserted into the holding recesses 127a and 127b) of specific portions of the holding parts <NUM> and <NUM> may have a hook shape that is coupled to one side of the protruding structure or a hook shape that is inserted into the recessed structure.

<FIG> is a view illustrating an example of a connection relationship of, among configurations of the wearable electronic device, the structure of the first strap and the housing according to various embodiments.

State <NUM> illustrates a direction of the first strap <NUM>, in which an inside of the first strap coupling part 139a is observed, and state <NUM> illustrates a state, in which the first holding part <NUM> of the first strap <NUM> is inserted into the first holding recess 127a. State <NUM> illustrates a state (or a maximum movement state), in which the second holding part <NUM> is pressed to be moved by a specific distance in the xz axis direction while the first holding part <NUM> of the first strap <NUM> is inserted into the first holding recess 127a, and state <NUM> illustrates a state, in which the first holding part <NUM> of the first strap <NUM> is inserted into the first holding recess 127a and the second holding part <NUM> is inserted into the second holding recess 127b.

Referring to <FIG>, as in state <NUM>, the first strap fixing part 131_2 may be disposed on one side (e.g., a periphery in the -x axis direction) of the first strap short body 131_1, and a holding body <NUM> may be fixed to the first strap fixing part 131_2. The first strap fixing part 131_2 may include a lower end part that defines a periphery of the first strap short body 131_1 in the -x axis direction, and an extension part that extends from an upper end of the first strap short body 131_1 in the -x axis direction and having a thickness that is smaller than that of the first strap short body 131_1. The holding body <NUM> may have a structure that is the same as or similar to that of the first strap fixing part 131_2. For example, the holding body <NUM> may include a lower end part that is fixed to a lower end part of the first strap fixing part 131_2 and supports the second holding part <NUM>, and an upper end part that is disposed below the extension part of the first strap fixing part 131_2 and extends in the -x axis direction such that at least a portion thereof defines the first holding part <NUM>. The first holding part <NUM> may include a basic base 310a that extends in the -x axis direction in the upper end part of the holding body <NUM>, and a holding area 310b that extends from a periphery of the basic base 310a in a diagonal direction between the z axis and the -x axis. A size of the first holding recess 127a may be formed to be larger (or thicker) than a thickness of an end (e.g., the holding area 310b) of the first holding part <NUM>. The first holding part <NUM> may be formed at at least a portion of an upper side (e.g., the -z axis direction) of the holding body <NUM>, and the second holding part <NUM> may be disposed at at least a portion of a lower side (e.g., the -z axis direction) or a side surface (e.g., -x axis direction) thereof.

As in state <NUM>, the display <NUM> may be seated on an upper side of the wearable electronic device <NUM>, and the rear cover <NUM> may be coupled to a lower side of the housing <NUM>. An empty space that passes through the housing <NUM> upwards and downwards may be formed at at least a portion of an inside of the housing <NUM>, and at least some of the above-mentioned electronic elements <NUM> may be disposed in the empty space of the inside of the housing <NUM>. The first holding part <NUM> may include the basic base 310a that extends from the holding body <NUM>, and the holding area 310b that extends from the basic base <NUM>10a and at least a portion of which is inserted into the first holding recess 127a. An entire shape of the first holding part <NUM> may have an "L" shape, of which left and right sides are reversed. The second holding part <NUM> may be formed as a separate structure to be coupled to one side of the holding body <NUM>. For example, the second holding part <NUM> may be moved in an upward/downward direction (e.g., the -z axis direction or the z axis direction) according to a pressure applied from an outside in the upward/downward direction after being coupling to a side surface of the holding body <NUM>. The first holding part <NUM> may be disposed in a diagonal direction between the z axis and the -x axis in a state, in which the first strap short body 131_1 is disposed horizontally. The second holding part <NUM> may include a holding rail (or a holding boss) that faces the -z axis direction in a state, in which the first strap short body 131_1 is disposed horizontally. In a process of coupling the first strap <NUM> to the strap connecting structure 120a, the first holding part <NUM> may be inserted into the first holding recess 127a while being introduced through the opening <NUM> of the strap connecting structure 120a after the first strap short body 131_1 is positioned horizontally on one side of the housing <NUM>.

According to various embodiments, a periphery of the first strap fixing part 131_2 in the -x axis direction may be disposed to cover at least a portion of an upper side (e.g., the z axis direction) of the first strap coupling part 139a. The first holding part <NUM> may protrude upwards (the z axis direction) further than peripheral structures (e.g., the first wing part <NUM> and the second wing part <NUM>) with respect to the z axis direction. The second holding part <NUM> may protrude downwards (the -z axis direction) further than peripheral structures (e.g., the first wing part <NUM> and the second wing part <NUM>) with respect to the -z axis direction.

As in <FIG>, the holding body <NUM> may provide a holding space 320a, in which the second holding part <NUM> may be seated. At least one fixing rib 320c and a holding step part 320b may be disposed in the holding space 320a such that the second holding part <NUM> is prevented from being separated from the holding space 320a after being seated.

The holding body <NUM> may include a holding part bottom 320d that supports the second holding part <NUM>. A part of the holding part bottom 320d, which extends in the -x axis direction, may define the first holding part <NUM>. A size of the holding part bottom 320d may correspond to a size of the second holding part <NUM>. According to various embodiments, a length of the first holding part <NUM> in the y axis (or the -y axis) may be larger than a length of the second holding part <NUM> in the y axis (or the -y axis).

As in <FIG> and <FIG>, the second holding part <NUM> may include a first holding base <NUM>, of which a thickness in the x axis is larger than a length thereof in the y axis and has a specific curvature between the y axis and the -y axis with respect to the z axis, a first holding boss <NUM> that is formed from a periphery (e.g., a periphery in the -x axis) of one side of the first holding base <NUM> in a first direction (e.g., -z axis direction), a first hook 231a and a second hook 231b formed in a second direction (e.g., the z axis direction) of the first holding base <NUM>, and a first elastic fixing structure <NUM> and a second elastic fixing structure <NUM> formed between the first hook 231a and the second hook 231b. In the above description, two elastic fixing structure are exemplified, but the disclosure is not limited thereto. For example, the second holding part <NUM> may have one elastic fixing structure or three or more elastic fixing structures.

The first holding base <NUM> may include a plate shape that has a thickness in the z axis direction, which is smaller than a thickness in the x axis direction, has a convex shape when viewed in the z axis direction, has a concave shape when viewed in the -z axis direction, and has a length in the y axis direction that is larger than a length in the x axis direction.

The first hook 231a may be formed to protrude from a periphery of the first holding base <NUM> in the y axis, in the z axis direction, and a protrusion direction of the hook may be an outward direction (e.g., the y axis direction) of one side with respect to a center point of the first holding base <NUM>. The first hook 231a, for example, may be coupled to the holding step part 320b formed in the holding body <NUM>. The second hook 231b may be formed to protrude from a periphery of the first holding base <NUM> in the - y axis, in the z axis direction, and a protrusion direction of the second hook 231b may be an outward direction (e.g., the -y axis direction) of an opposite side with respect to the center point of the first holding base <NUM>. The second hook 231b may be coupled to the holding step part formed in an opposite direction to the holding step part 320b of the holding body <NUM>, to which the first hook 231a is coupled.

The first elastic fixing structure <NUM> may include two fixing structures 232_1 and 232_2 that are formed to be close to the first hook 231a and are spaced apart from each other by a specific interval while facing each other, and a side wall that connects the two fixing structures 232_1 and 232_2 such that a mounted first elastic member 235a is not separated. The first elastic member 235a may be inserted and fixed between the two spaced fixing structures 232_1 and 232_2. The first elastic member 235a, for example, may have a "V" shape. Upper ends (e.g., bifurcated parts) of the first elastic member 235a may be seated in and fixed to the first fixing structure 232_1 and the second fixing structure 232_2, respectively, and a lower end (e.g., a tip part) of the first elastic member 235a may be disposed to protrude in the z axis direction through a space between the two fixing structures 232_1 and 232_2. In this relation, a length of the first elastic member 235a in the z axis direction may be formed to be larger than extension lengths of the first fixing structure 232_1 and the second fixing structure 232_2 in the z axis direction. An included angle of the "V" shape of the first elastic member 235a becomes larger while a pressure is applied to the second holding part <NUM> from an outside, and a height thereof, which protrudes in the z axis direction may be reduced. The second holding part <NUM> may be moved in the z axis direction until opposite peripheries of the "V" shape of the first elastic member 235a contacts the side wall of the first fixing structure 232_1 and the side wall of the second fixing structure 232_2. When the pressure applied to the second holding part <NUM> is released, the first elastic member 235a may be disposed to recover a prior protrusion height to an opening of the upper end of the first elastic fixing structure <NUM>, and correspondingly, the second holding part <NUM> may return in the z axis direction. A second elastic member 235b also may exert an elastic force while being operated in a way that is the same as or similar to that of the first elastic member 235a.

The second elastic fixing structure <NUM> may have a structure that is the same as or similar to that of the first elastic fixing structure <NUM>.

The second elastic fixing structure <NUM> may be disposed to be close to the second hook 231b. Alternatively, the second elastic fixing structure <NUM> may be disposed to be spaced apart from the first elastic fixing structure <NUM> by a specific interval. Accordingly, the second elastic fixing structure <NUM> may be disposed between the first elastic fixing structure <NUM> and the second hook 231b. In consideration of elasticity of the first holding base <NUM> of the second holding part <NUM>, a spacing distance between the first elastic fixing structure <NUM> and the second elastic fixing structure <NUM> may be larger than an interval between the first hook 231a and the first elastic fixing structure <NUM> or an interval between the second hook 231b and the second elastic fixing structure <NUM>. The second holding part <NUM> may be formed of a material that is the same as or similar to that of the first holding part <NUM> or the holding body <NUM>, except for the elastic member.
