[0023] Figure 1 illustrates an example of a head-worn electronic device worn by a user.

[0024] Referring to FIG. 1, the head-wearing electronic device (100), represented through state (101), may be described as a head-wearing electronic device that does not include a position adjustment assembly (120). In state (101), the length of the band (110) of the head-wearing electronic device (100) may be shorter than the circumference of the user's head. In state (101), the user may feel discomfort wearing the head-wearing electronic device (100). For example, a position adjustment assembly (120) may be required for the head-wearing electronic device (100) so that the length of the band (110) is appropriate for the user's head.

[0025] The head-worn electronic device (100), as indicated by state (102), can be described as a head-worn electronic device that does not include a structure for fixing the length of the band. In state (102), the band length of the head-worn electronic device (100) can be extended by an external force (e.g., an impact transmitted from the user's head).

[0026] In the above state (102), the second housing (140) of the head-worn electronic device (100) can move in a first direction (150). The second housing (140) moving in the first direction can move away from the first housing (130). The above state (102) can be changed or switched to a state (103) depending on the second housing (140) moving away from the first housing (130).

[0027] State (103) may indicate a state in which the length of the band (110) of the head-worn electronic device (100) is longer than the circumference of the user's head. In state (103), the head-worn electronic device (100) worn by the user may not be supported on the user's head. In state (103), since the head-worn electronic device (100) is not supported by the user's head, in state (103), the head-worn electronic device (100) may be moved in a second direction (160) (e.g., the direction of gravity). The movement of the head-worn electronic device (100) in the second direction (160) may not be intended by the user. Since the movement of the head-worn electronic device (100) in the second direction (160) is not intended by the user, a mechanism to maintain the length of the band (110) regardless of (or independently of) external force may be required within the head-worn electronic device (100).

[0054] According to one embodiment, the front panel (213) may cover at least a portion of the components within the first housing (130) so that the components within the first housing (130) are not visible from the outside. The front panel (213) may be disposed on the first housing (130). For example, the front panel (213) may be disposed on the first support portion (211a) of the first housing (130).

[0055] According to one embodiment, the visor (214) may be disposed on the first housing (130). The visor (214) may be disposed on the front panel (213). For example, at least a portion of the visor (214) may be formed of a substantially transparent or substantially translucent material so that the camera of the head-worn electronic device (100) (e.g., the camera module (180) of FIG. 1) can receive light from outside the head-worn electronic device (100), but is not limited thereto.

[0056] According to one embodiment, the second housing (140) may include a third case (221) and / or a fourth case (222). The third case (221) and the fourth case (222) may be combined with each other. The third case (221) and the fourth case (222) may form (or define) the second housing (140) by being combined with each other.

[0057] According to one embodiment, the third case (221) may face the second case (212). The third case (221) may support the second pad (260). The second pad (260) may be placed on the third case (221). A portion of the adjustment module (292) may protrude (or be exposed) to the outside of the third case (221).

[0058] According to one embodiment, the fourth case (222) may be coupled to the third case (221). Another part of the band (110) may extend within the third case (221) and the fourth case (222). The position adjustment assembly (120) may protrude outside the fourth case (222).

[0059] Figure 4 illustrates the change in the length of the band of a head-worn electronic device.

[0060] Referring to FIG. 4, the band (110) may include a first side band (420) and a second side band (430). The first side band (420) and the second side band (430) may be positioned to overlap. The length of the band (110) may be adjusted (or changed) through positional adjustment between the first side band (420) and the second side band (430).

[0061] The position adjustment assembly (120) may include a wheel part (440). The position adjustment assembly (120) may be located at the portion where the first side band (420) and the second side band (430) overlap. The wheel part (440) may be rotated in a defined rotational direction. For example, the wheel part (440) may be rotated in a first defined rotational direction (e.g., counterclockwise (450)). For example, the wheel part (440) may be rotated in a second defined rotational direction (e.g., clockwise (460)) opposite to the first defined rotational direction.

[0062] The first state (401) can be described as a state in which the wheel part (440) rotates according to an external force. In the first state (401), an external force (e.g., user input) can be applied to the wheel part (440). When the wheel part (440) rotates in the first defined rotational direction (e.g., counterclockwise (450)) according to the external force applied to the wheel part (440), the length of the band (110) may be increased. For example, when the wheel part (440) rotates in the first defined rotational direction, the first side band (420) may move away from the second side band (430) along the length of the band (110), as indicated by the arrow (455). In the first state (401), when the wheel part (440) rotates in the second defined rotational direction (e.g., clockwise (460)), the length of the band (110) may be decreased. For example, when the wheel part (440) is rotated in the second defined rotational direction, as indicated by the arrow (465), the first side band (420) may come closer to the second side band (430) in the longitudinal direction of the band (110).

[0063] A second state (402) can be described as a state in which the wheel part (440) is stopped by a band length fixing mechanism. In the second state (402), an external force (e.g., an impact transmitted from the user's head) may be applied to the band (110). In response to the external force applied to the band (110) (e.g., distinguished from the external force applied to the wheel part (440)) to cause the first side band (420) and the second side band (430) to move apart from each other in the longitudinal direction of the band (110) as indicated by the arrow (475), the band length fixing mechanism of the head-worn electronic device may cause a frictional force applied in the direction (476). Depending on the frictional force, the state of the wheel part (440) may be maintained in a stopped state (470) despite the external force.

[0064] FIG. 5 is an exploded perspective view of the band and position adjustment assembly of a head-worn electronic device.

[0065] Referring to FIG. 5, the band (110) may include a first side band (420) and a second side band (430). The first side band (420) may include a first rack gear (541). The second side band (430) may include a second rack gear (542).

[0066] The position adjustment assembly (120) may include the circular stop part (410), the gear part (510), the spring (520), the locking part (530), the connecting part (560), and the wheel part (440). The components of the position adjustment assembly (120) (e.g., the circular stop part (410), the gear part (510), the spring (520), the locking part (530), the connecting part (560), and the wheel part (440)) are merely exemplary. Some components (e.g., the spring (520) and the connecting part (560)) may be omitted from the position adjustment assembly (120).

[0067] The fourth case (222) included in the second housing can cover the band (110) and the position adjustment assembly (120). The fourth case (222) can protect the band (110) and the position adjustment assembly (120) from external impact. The fourth case (222) can be formed from a relatively hard material (e.g., metal).

[0068] The wheel part (440) can be connected to the connecting part (560). The wheel part (440) can be rotated based on (or in response to) user input. The connecting part (560) connected to the wheel part (440) can be rotated according to the rotation of the wheel part (440).

[0069] The connecting part (560) may include at least one projection (570). The at least one projection (570) may be cylindrical in shape. The at least one projection (570) may be symmetrical with respect to the axis of rotation (590). For example, the at least one projection (570) may include four first projections (571), second projections (572), third projections (573), and fourth projections (574). The connecting part (560) may be connected to the locking part (530). The locking part (530) may rotate according to the rotation of the connecting part (560). The connection between the connecting part (560) and the locking part (530) will be described with reference to FIG. 8.

[0070] The locking part (530) may include a first locking part (531) and a second locking part (532). The first locking part (531) and the second locking part (532) may have a fan shape. However, various embodiments are not limited thereto. The first locking part (531) and the second locking part (532) may have a triangular shape (or a rounded triangular shape). The locking part (530) may be connected to the gear part (510). In a state where an external force is applied to the wheel part (e.g., the first state (401)), the locking part (530) may transmit force to the gear part (510). The gear part (510) may rotate according to the force transmitted from the gear part (510). In a state where the wheel part (440) is stopped by the band length fixing mechanism (e.g., the second state (402)), the locking part (530) can receive power from the gear part (510).

[0071] The spring (520) may be positioned between the first locking part (531) and the second locking part (532). The spring (520) may push the first locking part (531) and the second locking part (532) away from the axis of rotation (590). The spring (520) will be described in detail with reference to FIG. 6.

[0072] The gear part (510) may include a drive gear (511). The drive gear (511) may be positioned to mesh with the first rack gear (541) and the second rack gear (542), respectively. The first rack gear (541) and the second rack gear (542) may be moved through the rotation of the drive gear (511).

[0073] The circular stop part (410) may include a groove portion (415) into which a drive gear (511) is inserted. The side surface (e.g., the z-axis side) of the groove portion (415) may be open. As a non-limiting example, the drive gear (511) may be exposed through the side surface of the groove portion (415). The drive gear (511) may include a portion exposed through the side surface of the groove portion (415). The first rack gear (541) and the second rack gear (542) may each engage with the portion of the drive gear (511) exposed through the side surface of the groove portion (415). The circular stop part (410) may surround the lateral side portion of the locking part (530). In a state where the wheel part (440) is stopped by the band length fixing mechanism (e.g., the second state (402)), the circular stop part (410) may come into contact with the side of the locking part (530). In the state (e.g., the second state (402)), friction may occur at the point where the circular stop part (410) and the locking part (530) come into contact.

[0074] Figure 6 is a cross-sectional view of a position adjustment assembly of a head-worn electronic device.

[0075] Referring to FIG. 6, the locking part (530) may be in the shape of a sector. The parts corresponding to the radius of the sector of the locking part (530) may be defined as second parts (650).

[0076] The gear part (510) may further include a first protruding part (610) and a second protruding part (620). The first protruding part (610) and the second protruding part (620) may protrude in the +y direction. The first protruding part (610) and the second protruding part (620) may have a trapezoidal shape (or a rounded trapezoidal shape). The second protruding part (620) may be symmetrical to the first protruding part (610) with respect to the center (690) of the circular stop part (410). At least a portion of the first protruding part (610) and the second protruding part (620) may be positioned to be in contact with the second parts (650).

[0077] The circular stop part (410), the locking part (530), the first protrusion (610), the second protrusion (620), at least one projection (570) of the connecting part (560), and the spring (520) may be arranged on the same plane. In a state where the wheel part (440) is rotated according to an external force (e.g., the first state), the connecting part (560) may be rotated. At least one projection (570) of the connecting part (560) may apply force to the locking part (530). In a state where the wheel part (440) is rotated according to an external force (e.g., the first state), the locking part (530) may be rotated according to the force caused by at least one projection (570) of the connecting part (560). A locking part (530), which rotates according to a force from at least one projection (570) of a connecting part (560), can push a first protrusion (610) and a second protrusion (620). The gear part (510) can be rotated by the locking part (530) pushing the first protrusion (610) and the second protrusion (620).

[0078] A spring (520) may be positioned between the first locking part (531) and the second locking part (532). The spring (520) may push the locking part (530) in a direction away from the center (690) of the circular stop part (410). When the locking part (530) presses the circular stop part (410), a normal force may be applied to the locking part (530). A frictional force generated between the locking part (530) and the circular stop part (410) may be generated according to the normal force. The spring (520) may reinforce the frictional force between the locking part (530) and the circular stop part (410).

[0079] FIG. 7 illustrates the shape of a wheel part and a connecting part included in a position adjustment assembly of a head-worn electronic device.

[0080] Referring to FIG. 7, the state (701) may correspond to a state in which the wheel part (440) is rotated according to an external force (e.g., the first state (401)). The state (701) may represent the state of a connecting part (560) that is rotated by the wheel part (440). The wheel part (440) may have a cylindrical shape. The cylindrical surface of the wheel part (440) arranged in the -y-axis direction may be open. The wheel part (440) may be rotated in a defined direction (750) in response to user input. The defined direction (750) may be clockwise or counterclockwise.

[0081] The above connecting part (560) may have a cylindrical shape. The connecting part (560) may be inserted into the interior of the wheel part (440) through an open portion of the wheel part (440). The connecting part (560) may be connected to the wheel part (440) by a screw structure (710). The connecting part (560), connected to the wheel part by a screw structure, may rotate integrally with the wheel part (440).

[0082] The connecting part (560) may include at least one projection (570) that contacts the locking part (530). The connecting part (560) may be formed from a different material distinct from the material of the wheel part (440). The connecting part (560) may be formed from a metal material. The connecting part (560) may include a material having relatively high durability in relation to contact with the locking part (530).

[0083] The above at least one projection (570) may protrude from the wheel part (440). When the above at least one projection (570) protrudes from the wheel part (440), the wheel part (440) may come into direct contact with the locking part (530). When the wheel part (440) comes into direct contact with the locking part (530), the locking part (530) may rotate according to the rotation of the wheel part (440).

[0084] FIG. 8 illustrates the relationship between the connecting part and the locking part included within the position adjustment assembly of a head-worn electronic device.

[0085] Referring to FIG. 8, the first locking part (531) and the second locking part (532) may include one or more groove portions (810). For example, the first locking part (531) may include a first groove portion (811) and a second groove portion (812), and the second locking part (532) may include a third groove portion (813) and a fourth groove portion (814). The first groove portion (811) and the second groove portion (812) may be defined by a side wall of the first locking part (531) protruding from the base of the first locking part (531). The third groove portion (813) and the fourth groove portion (814) may be defined by a side wall of the second locking part (532) protruding from the base of the second locking part (532). One or more groove portions (810) of the second locking part (532) may be symmetrical with respect to one or more groove portions (810) of the first locking part (531) with respect to the center (690) of the circular stop part (410).

[0086] At least one projection (570) of the connecting part (560) may be inserted into one or more groove portions (810) of the first locking part (531) or one or more groove portions (810) of the second locking part (532), respectively. For example, the first projection (571) may be inserted into the first groove portion (811) according to the connection between the connecting part (560) and the locking part (530). The second projection (572) may be inserted into the second groove portion (812) according to the connection between the connecting part (560) and the locking part (530). The third projection (573) may be inserted into the third groove portion (813) according to the connection between the connecting part (560) and the locking part (530). The fourth projection (574) can be inserted into the fourth groove portion (814) according to the connection of the connecting part (560) and the locking part (530).

[0087] State (801) represents a state in which at least one projection (570) of the connecting part (560) and one or more groove portions (810) of the locking part (530) are joined together. In a state in which the wheel part (440) is rotated according to an external force (e.g., the first state), the force acting between the connecting part (560) and the locking part (530) will be described in detail with reference to FIG. 9.

[0088] FIG. 9 illustrates the relationship between the connecting part, the locking part, and the circular stop part when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a rotated state.

[0089] Referring to FIG. 9, the state (901) can be described as a state in which the locking part (530) receives force from the connecting part (560) in a state in which the wheel part (440) rotates according to an external force (e.g., the first state (401)).

[0090] For example, when the connecting part (560) rotates in a defined rotational direction (e.g., counterclockwise (950)), the second groove portion (812) of the first locking part (531) may receive a force (910) from the second projection (572). The third groove portion (813) of the second locking part (532) may receive a force (920) from the third projection (573). By at least a portion of the force received from the second projection (572) and the third projection (573), the locking part (530) may be moved toward the center direction (930) of the circular stop part (410) along the contact surface with the first projection (610) and the second projection (620). The locking part (530) moved toward the center direction (930) of the circular stop part (410) may be separated from the circular stop part (410). Depending on the locking part (530) spaced apart from the circular stop part (410), friction may not occur between the locking part (530) and the circular stop part (410). The locking part (530) to which friction is not applied may be rotated in a defined rotational direction (e.g., counterclockwise (950)).

[0091] For example, when the connecting part (560) rotates in the opposite direction to the defined rotational direction (e.g., clockwise), the first groove portion (811) of the first locking part (531) may receive force from the first projection (571). The fourth groove portion (814) of the second locking part (532) may receive force from the fourth projection (574). By at least a portion of the force received from the first projection (571) and the fourth projection (574), the locking part (530) may move toward the center direction (930) of the circular stop part (410) along the contact surface with the first projection (610) and the second projection (620). The locking part (530) moved toward the center direction (930) of the circular stop part (410) may be separated from the circular stop part (410). Depending on the locking part (530) spaced apart from the circular stop part (410), frictional force may not occur between the locking part (530) and the circular stop part (410). The locking part (530) to which frictional force is not applied may be rotated in the opposite direction to the defined rotational direction (e.g., clockwise).

[0092] The spring (520) can resist movement toward the center (690) of the circular stop part (410) of the locking part (530). The elastic modulus of the spring (520) can determine the strength of user input required to rotate the wheel part (440).

[0093] FIG. 10 illustrates the relationship between the locking part and the gear part when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a rotated state.

[0094] Referring to FIG. 10, the state (1001) can be described as a state in which the gear part (510) receives force from the locking part (530) in a state in which the wheel part (440) rotates according to an external force (e.g., the first state (401)).

[0095] For example, when the locking part (530) rotates in a second defined rotational direction (e.g., counterclockwise (1060)), the first locking part (531) can transmit force (1050) to the second protrusion (620), and the second locking part (532) can transmit force (1050) to the first protrusion (610). By the force (1050) transmitted to the first protrusion (610) and the second protrusion (620), the gear part (510) can be rotated in a fourth defined rotational direction (e.g., counterclockwise (1070)).

[0096] For example, when the locking part (530) rotates in the opposite direction of the second defined rotational direction (e.g., clockwise), the first locking part (531) can transmit force to the first protrusion (610), and the second locking part (532) can transmit force to the second protrusion (620). Due to the force transmitted to the first protrusion (610) and the second protrusion (620), the gear part (510) can be rotated in the opposite direction of the fourth defined rotational direction (e.g., clockwise).

[0097] FIG. 11 illustrates the relationship between the gear part and the band when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a rotated state.

[0098] Referring to FIG. 11, the state (1101) may represent a state in which the first rack gear (541) is moved by the drive gear (511) in a state in which the wheel part (440) is rotated according to an external force (e.g., a first state). The drive gear (511) may protrude in the -y direction from the gear part (510). The drive gear (511) protruding from the gear part (510) may rotate integrally with the gear part (510).

[0099] The drive gear (511) can be inserted into the groove portion (415) of the circular stop part (410). The exposed portion of the drive gear (511) can be configured to mesh with the first rack gear (541). The first rack gear (541) can convert the rotational motion of the drive gear (511) into linear motion. For example, in state (1101), the first rack gear (541) can be moved in a defined direction (e.g., -x-axis direction (1160)) when the drive gear (511) rotates in a defined rotational direction (e.g., clockwise (1150)). For example, in state (1101), the first rack gear (541) can be moved in a direction opposite to the defined direction (e.g., x-axis direction) when the drive gear (511) rotates in a direction opposite to the defined rotational direction (e.g., counterclockwise).

[0100] Referring again to FIG. 4, in a state where the wheel part (440) is rotated according to an external force (e.g., the first state (401)), the connecting part (560), the locking part (530), and the gear part (510) can be rotated in a first defined rotational direction (e.g., counterclockwise (450)) according to the rotation of the wheel part (440) in a first defined rotational direction (e.g., counterclockwise (450)). According to the rotation of the gear part (510), the driving gear (511) can be rotated in a first defined rotational direction (e.g., counterclockwise (450)). According to the rotation of the driving gear (511), the first rack gear (541) can move in the +x axis direction, and the second rack gear (542) can move in the -x axis direction. As the first rack gear (541) and the second rack gear (542) move, the first side band (420) can move away from the second side band (430) in the longitudinal direction of the band (110), as indicated by the arrow (455).

[0101] In a state where the wheel part (440) is rotated according to an external force (e.g., the first state (401)), the connecting part (560), the locking part (530), and the gear part (510) can be rotated in a second defined rotational direction (e.g., clockwise (460)) according to the rotation of the wheel part (440) in a second defined rotational direction (e.g., clockwise (460)). According to the rotation of the gear part (510), the driving gear (511) can be rotated in a second defined rotational direction (e.g., clockwise (460)). According to the rotation of the driving gear (511), the first rack gear (541) can move in the -x axis direction, and the second rack gear (542) can move in the +x axis direction. As the first rack gear (541) and the second rack gear (542) move, the first side band (420) can move closer to the second side band (430) in the longitudinal direction of the band (110), as indicated by the arrow (465).

[0102] FIG. 12 illustrates the relationship between the gear part and the band when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a stopped state.

[0103] Referring to FIG. 12, state (1201) may represent a state in which force is transmitted from the first rack gear (541) to the drive gear (511) while the wheel part (440) is stopped by the band length fixing mechanism (e.g., the second state (402)). The drive gear (511) may be inserted into the groove portion (415) of the circular stop part (410). The exposed portion of the drive gear (511) may be configured to mesh with the first rack gear (541).

[0104] The drive gear (511) can convert the linear motion of the first rack gear (541) into rotational motion. For example, in the state (1201), when the first rack gear (541) moves in a defined direction (e.g., -x-axis direction (1260)), the drive gear (511) can be rotated in a defined rotational direction (e.g., clockwise (1270)). In the state (1201), the drive gear (511) can be maintained in a stationary state despite the force transmitted from the first rack gear (541).

[0105] Referring again to FIG. 4, when the wheel part (440) is in a stopped state (e.g., the second state (402)) by the band length fixing mechanism, the gear part (510), the locking part (530), and the connecting part (560) can be maintained in a stopped state (470) despite an external force applied to the band (110) (e.g., an impact transmitted from the user's head). The locking part (530) (not shown) may have a mechanism that causes the gear part (510) to be maintained in a stopped state by the external force applied to the band (110). The mechanism of the locking part (530) may be described with reference to FIG. 13 and FIG. 14.

[0106] FIG. 13 illustrates the relationship between the gear part and the locking part when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a stopped state.

[0107] Referring to FIG. 13, state (1301) represents a state in which the gear part (510) is fixed by the locking part (530) while the wheel part (440) is stopped by the band length fixing mechanism (e.g., the second state (402)). The locking part (530) can receive force (1350) from the first protrusion (610) and the second protrusion (620). For example, when the gear part (510) is rotated in a defined rotational direction (e.g., counterclockwise (1360)), the first locking part (531) can receive force (1350) from the first protrusion (610), and the second locking part (532) can receive force (1350) from the second protrusion (620). The locking part (530) receiving the force (1350) may press the circular stop part (410) in a direction away from the center (690) of the circular stop part (410). By pressing, a normal force applied to the locking part (530) may be generated. The magnitude of the frictional force generated between the locking part (530) and the circular stop part (410) may be proportional to the magnitude of the normal force. The magnitude of the frictional force between the locking part (530) and the circular stop part (410) may change depending on the change in the magnitude of the force (1350) applied to the locking part (530). The action of the force (1350) may be explained with reference to FIG. 14.

[0108] FIG. 14 illustrates the direction of the force applied to the locking part when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a stopped state.

[0109] Referring to FIG. 14, the state (1401) indicates a state in which a defined force (1431) generates friction between the first locking part (531) and the circular stop part (410). The defined force (1431) may be defined as the force applied by the first protruding part (610) to the first locking part (531). For example, when the gear part (510) rotates in a defined direction (e.g., counterclockwise (1410)), the first protruding part (610) of the gear part (510) may apply the defined force (1431) to the first locking part (531).

[0110] The first straight line (1421) can be defined as a line connecting the center (690) of the circular stop part (410) and the point of contact between the first protruding part (610) and the first locking part (531). The second straight line (1441) can be defined as a line extending in the direction of the defined force (1431) from the point of contact between the first protruding part (610) and the first locking part (531). The third straight line (1451) can be defined as a straight line parallel to one of the second parts (650) of the first locking part (531) and tangent to the arc part of the first locking part (531). The second straight line (1441) can be perpendicular to the first straight line (1421). The smaller of the angles between the second straight line (1441) and the third straight line (1451) can be defined as X (1461). The magnitude of the normal force applied to the first locking part (531) is It may be. The frictional force between the first locking part (531) and the circular stop part (410) may be generated based on the normal force.

[0111] State (1402) indicates a state in which a defined force (1432) generates a relatively larger frictional force compared to state (1401). The defined force (1432) may be defined as the force applied by the first protrusion (610) to the first locking part (531). For example, when the gear part (510) rotates in a defined direction (e.g., counterclockwise (1410)), the first protrusion (610) of the gear part (510) may apply the defined force (1432) to the first locking part (531).

[0112] The fourth straight line (1422) can be defined as a line connecting the center (690) of the circular stop part (410) and the point of contact between the first protruding part (610) and the first locking part (531). The fifth straight line (1442) can be defined as a line extending in the direction of the force (1432) from the point of contact between the first protruding part (610) and the first locking part (531). The sixth straight line (1452) can be defined as a straight line parallel to one of the second parts (650) of the first locking part (531) and tangent to the arc part of the first locking part (531). The fifth straight line (1442) can be perpendicular to the fourth straight line (1422). The fifth straight line (1442) can be perpendicular to the sixth straight line (1452). When the fifth straight line (1442) and the sixth straight line (1452) are perpendicular, the magnitude of the normal force acting on the first locking part (531) may be the magnitude of the defined force (1432).

[0113] The frictional force generated between the locking part (530) and the circular stop part (410) can be determined based on the angle between the second parts (650) of the locking part (530). For example, the angle between the second parts (650) in state (1401) may be greater than the angle between the second parts (650) in state (1402). The magnitude of the frictional force generated between the locking part (530) and the circular stop part (410) in state (1401) may be smaller than the magnitude of the frictional force in state (1402).

[0114] In state (1401), if the frictional force generated between the locking part (530) and the circular stop part (410) is greater than the force attempting to rotate the locking part (530) as part of the defined force (1431), the locking part (530) may have a band length fixing mechanism even without a spring (520) (not shown).

[0115] FIG. 15 illustrates the relationship between the locking part and the circular stop part when the wheel part included in the position adjustment assembly of the head-worn electronic device is in a stopped state.

[0116] Referring to FIG. 15, state (1501) may represent a state in which frictional force (1560) occurs between a locking part (530) and a circular stop part (410) when the wheel part (440) is stopped by a band length fixing mechanism (e.g., the second state (402)). In state (1501), the locking part (530) may be pressed in a defined direction (1550). The locking part (530) pressed in the defined direction (1550) may come into contact with the circular stop part (410). Frictional force (1560) may occur at the contact area (1510) between the locking part (530) and the circular stop part (410).

[0117] An enlarged view of the contact portion (1510) between the first locking part (531) and the circular stop part (410) is shown. The first locking part (531) may include a first portion (1511) corresponding to a fan arc portion. The circular stop part (410) may include a third portion (1512) that contacts the locking part (530). The friction coefficient of the first portion (1511) may be greater than the friction coefficient of other portions of the locking part (530). The first portion (1511) may be formed from TPU (thermoplastic polyurethane). The first portion (1511) may be formed from PC (polycarbonate). The first portion (1511) may be formed from silicone. The friction coefficient of the third portion (1512) may be greater than the friction coefficient of other portions of the circular stop part (410). The third part (1512) can be formed from TPU. The third part (1512) can be formed from PC. The third part (1512) can be formed from silicon.

[0118] As a non-limiting example, the friction coefficient between the first part (1511) of the locking part (530) and the third part (1512) of the circular stop part (410) is It may be greater than (not shown). The friction coefficient between the first part (1511) and the third part (1512) is In the case of a larger size, the locking part (530) may have a mechanism for fixing the band length even when there is no spring (520) (not shown).
