[0023] Figures 1a, 1b, and 1c illustrate electronic devices for charging an exemplary wearable device.

[0024] Referring to FIGS. 1A, 1B, and 1C, an electronic device (100) for charging a wearable device (10) may include a housing (110) and an elastic structure (120). The electronic device (100) may be referred to as a charging device for charging the wearable device (10). The electronic device (100) may supply power to the wearable device (10).

[0025] According to one embodiment, the wearable device (10) can be worn by a user. The user may refer to a person who wears the wearable device (10). The wearable device (10) may be worn on a part of the user's body. For example, the wearable device (10) may be worn on a part of the user's body. For example, the wearable device (10) may be fastened to a part of the user's body. For example, the wearable device (10) may be detachable from a part of the user's body.

[0026] For example, the wearable device (10) may be worn by the user and thus come into contact with a part of the user's body. For example, the wearable device (10) may be configured to acquire information related to the user through a part of the user's body by being worn by the user. For example, the wearable device (10) may provide the user with information indicating the user's status based on the acquired information related to the user. For example, the wearable device (10) may be configured to display information indicating the user's status through a display (not shown) of the wearable device (10) and / or an external electronic device (not shown) connected to the wearable device (10), thereby providing the user with information indicating the user's status. However, the present invention is not limited thereto.

[0027] For example, a part of the user's body on which the wearable device (10) is worn may be the user's finger. For example, the wearable device (10) may have a ring shape so that the wearable device (10) can be worn on the user's finger. However, the present invention is not limited thereto. The wearable device (10), which may be referred to as a wearable device, may have a shape corresponding to a part of the user's body so that it can be worn on that part.

[0028] According to one embodiment, the electronic device (100) may be configured to charge the wearable device (10). For example, the electronic device (100) may supply power to the wearable device (100) through wireless charging by coming into contact with at least a portion of the wearable device (10). For example, although not shown, the electronic device (100) may include a coil (e.g., coil (410) of FIG. 5B) for charging the wearable device (10). The wearable device (10) may be configured to supply power to the coil (410). The coil (410) supplied with power may be configured to cause current to flow within another coil (61) adjacent to the coil (410) through electromagnetic induction with another coil (61 of FIG. 6) within the wearable device (10). By causing current to flow within the other coil (61), a battery (62 of FIG. 6) within the wearable device (10) may be charged. However, the present invention is not limited thereto.

[0029] According to one embodiment, the housing (110) may include a first surface (110a), a second surface (110b) opposite the first surface (110a), and a third surface (110c) surrounding a space between the first surface (110a) and the second surface (110b). For example, the first surface (110a) may be a surface on which the wearable device (10) is mounted. For example, the first surface (110a) may be a surface on which an elastic structure (120) for charging the wearable device (10) is disposed. For example, the first surface (110a) may be a surface of the housing (110) on which the elastic structure (120) is coupled. For example, the second surface (110b) may be a surface facing the first surface (110a) and spaced apart from the first surface (110a). For example, the second surface (110b) may be a surface that supports the housing (110). For example, the third surface (110c) may extend from the first surface (110a) to the second surface (110b). For example, the third surface (110c) may be disposed between the first surface (110a) and the second surface (110b). For example, the third surface (110c) may surround a space between the first surface (110a) and the second surface (110b). At least one electronic component (e.g., a motor (311) of FIG. 3A) of the electronic device (100) may be disposed within the space, but is not limited thereto.

[0030] According to one embodiment, the housing (110) may include a guide hole (111). For example, the guide hole (111) may penetrate at least a portion of the housing (110). For example, the guide hole (111) may be formed in a first surface (110a) on which the wearable device (10) is mounted. For example, the guide hole (111) may penetrate the first surface (110a). For example, the guide hole (111) may be connected from the first surface (110a) to a space surrounded by the first surface (110a), the second surface (110b), and the third surface (110c) of the housing (110). For example, the guide hole (111) may accommodate at least a portion of the elastic structure (120). For example, the guide hole (111) may be coupled with the elastic structure (120). For example, the guide hole (111) can guide the movement of at least a portion of the elastic structure (120). By including the guide hole (111), the housing (110) can reduce the elastic structure (120) for charging the wearable device (10) from being detached from the housing (110).

[0031] According to one embodiment, the elastic structure (120) may be coupled to the housing (110). The elastic structure (120) may be configured to supply power to the wearable device (10).

[0032] For example, the elastic structure (120) can be connected to the housing (110). For example, the elastic structure (120) can be coupled to the first surface (110a) of the housing (110). For example, the elastic structure (120) can be assembled onto the housing (110) by being at least partially disposed within the guide hole (111) of the housing (110). For example, a part of the elastic structure (120) can be disposed inside the housing (110) through the guide hole (111) of the housing (110). The remaining part of the elastic structure (120) can be exposed to the outside of the housing (110) and come into contact with the first surface (110a) of the housing (110).

[0033] For example, although not shown, the elastic structure (120) may include a coil (410) for charging the wearable device (10). The coil (410) may be disposed inside the elastic structure (120). For example, the elastic structure (120) may be configured to charge the wearable device (10) by coming into contact with at least a portion of the wearable device (10). For example, a portion of the elastic structure (120) where the coil (410) is disposed may come into contact with a power supply area of ​​the wearable device (10) (e.g., power supply area (10a) of FIG. 5A) where another coil (61) of the wearable device (10) is disposed. The above coil (410) may be configured to be arranged adjacent to the other coil (61) so that an induced current is generated in the other coil (61) through electromagnetic induction with the other coil (61). The wearable device (10) may be charged by the current flowing to the other coil (61) within the wearable device (10).

[0034] For example, the wearable device (10) may have a ring shape in order to be worn on a part of the user's body (e.g., a finger). Since the size of the part of the user's body on which the wearable device (10) is worn varies depending on the user wearing the wearable device (10), the size of the wearable device (10) having a ring shape and / or the size of the inner circumference of the wearable device (10) may vary. The elastic structure (120) of the electronic device (100) may be required to have a changeable structure in order to correspond to the size of the wearable device (10) that varies depending on the size of the part of the user's body. For example, at least a portion of the elastic structure (120) may be deformed in order to come into contact with the inner circumference surface of the wearable device (10) mounted on the first surface (110a) of the housing (110). The elastic structure (120) can increase the charging efficiency of the wearable device (10) by coming into contact with at least a portion of the wearable device (10). Regarding the change in the elastic structure (120), this will be described later in FIG. 2a and FIG. 2b.

[0035] According to one embodiment, the elastic structure (120) may include at least one of rubber and a spring. By including at least one of rubber and a spring, the elastic structure (120) may be at least partially elastically deformed. By being deformable, the elastic structure (120) may come into contact with a wearable device (10) mounted on the housing (110). By coming into contact with the wearable device (10), the elastic structure (120) may increase the charging efficiency of the wearable device (10).

[0036] According to one embodiment, the electronic device (100) may further include a guide structure (130) for guiding the position of the elastic structure (120). The guide structure (130) may be fastened to the housing (110). For example, the guide structure (130) may penetrate at least a portion of the elastic structure (120). For example, the guide structure (130) may, together with the guide hole (111), couple the elastic structure (120) to the housing (110). For example, at least a portion of the guide structure (130) may pass through the elastic structure (120), thereby reducing the elastic structure (120) from being detached from the housing (110).

[0037] According to the above-described embodiment, the electronic device (100) for charging the wearable device (10) can increase the charging efficiency of the wearable device (10) by including an elastic structure (120) that can be deformed according to the size of the wearable device (10). The electronic device (100) can reduce the detachment of the elastic structure (120) from the housing (110) by including a guide hole (111) and a guide structure (130).

[0038] Figure 2a is a top plan view of an electronic device in an exemplary first state. Figure 2b is a top plan view of an electronic device in an exemplary second state.

[0039] Referring to FIGS. 2A and 2B, an electronic device (100) for charging a wearable device (10) may include a housing (110) including a guide hole (111), and an elastic structure (120) coupled to the housing (110) and configured to supply power to the wearable device (10). According to one embodiment, the electronic device (100) may further include a guide structure (130) fastened to the housing (110).

[0040] According to one embodiment, the elastic structure (120) may include a first portion (121), a second portion (122), and a third portion (123). The first portion (121) may be at least partially disposed within a guide hole (111) of the housing (110). The second portion (122) may be rotatably coupled to the housing (110). The third portion (123) may connect the first portion (121) and the second portion (122). The third portion (123) may be deformable.

[0041] For example, the first part (121) may be a part that is coupled with the guide hole (111) of the housing (110). For example, the first part (121) may be a part that is at least partially disposed inside the housing (110) through the guide hole (111). For example, the first part (121) may be partially accommodated in the guide hole (111). For example, the first part (121) may be a part that comes into contact with the inner surface of the guide hole (111). For example, the first part (121) may be a part that includes one end of the elastic structure (120), but is not limited thereto. The first part (121) may be partially disposed in the guide hole (111), thereby reducing the elastic structure (120) from being detached from the housing (110) as the elastic structure (120) changes.

[0042] For example, the second portion (122) may be a portion that is rotatable with respect to the housing (110). For example, the second portion (122) may be a portion that is penetrated by a guide structure (130) that is fastened to the housing (110). For example, the second portion (122) may be rotatably coupled to the housing (110) by the guide structure (130). For example, the second portion (122) may be a portion that is spaced apart from the first portion (121) that is at least partially disposed within the guide hole (111). For example, the second portion (122) may surround at least a portion of the guide structure (130) that passes through the elastic structure (120).

[0043] For example, the third portion (123) may be a portion extending from the first portion (121) to the second portion (122). For example, the third portion (123) may be a portion configured to at least partially contact the wearable device (10). For example, the third portion (123) may be a portion that expands outward with respect to the second portion (122) configured to rotate with respect to the housing (110) by being deformed, or shrinks inward with respect to the second portion (122). For example, the third portion (123) may be a portion configured to supply power to the wearable device (10). The elastic structure (120) includes a third part (123) that is deformable according to the rotation of the second part (122), so that the third part (123) can be changed to come into contact with the wearable device (10) in response to various sizes of the wearable device (10). The elastic structure (120) can be changed so that the third part (123) comes into contact with the wearable device (10), so that the charging efficiency of the wearable device (10) having various sizes can be increased.

[0044] According to one embodiment, the guide structure (130) may be configured to provide an axis of rotation (a) of the second portion (122). For example, the guide structure (130) may penetrate at least a portion of the second portion (122). The guide structure (130) may be fastened to the housing (110) by passing through the second portion (122). The guide structure (130) may be fastened to the housing (110) to provide an axis of rotation (a) such that the second portion (122) can rotate with respect to the housing (110).

[0045] According to one embodiment, the third part (123) of the elastic structure (120) can be configured to change the distance (d) between the rotational axis (a) of the second part (122) and a position (p) of the third part (123) by being deformed by the rotation of the second part (122).

[0046] For example, as the second part (122) rotates around the rotation axis (a), the third part (123) connected to the second part (122) can be deformed. As the third part (123) is deformed, a position (p) of the third part (123) can move with respect to the rotation axis (a). As the position (p) moves with respect to the rotation axis (a), a distance (d) between the rotation axis (a) and the position (p) can change. For example, the position (p) of the third part (123) can be moved toward the rotation axis (a) of the second part (122) or toward the wearable device (10) mounted on the housing (110) according to the deformation of the third part (123) due to the rotation of the second part (122). The third part (123) can be configured to come into contact with the wearable device (10) having various sizes by being deformable so that the position (p) can move with respect to the rotation axis (a).

[0047] According to one embodiment, the second portion (122) of the elastic structure (120) can be configured to be rotatable in a first rotational direction (201) and a second rotational direction (202) opposite to the first rotational direction (201) with respect to the housing (110). The third portion (123) can be configured to provide a plurality of states including a first state in which a distance (d) between a rotational axis (a) of the second portion (122) and a position (p) of the third portion (123) is minimum by the rotation of the second portion (122), and a second state in which the distance (d) is maximum.

[0048] The first state of the electronic device (100) may be a state in which the distance (d) between the rotation axis (a) of the second part (122) and the position (p) of the third part (123) is the minimum distance. For example, the first state may be a state in which the position (p) is the farthest from the rotation axis (a). For example, the first state may be a state in which the third part (123) of the elastic structure (120) is contracted due to the restoring force of the elastic structure (120). For example, the first state may be a state in which the second part (122) can rotate in the second rotation direction (202) about the rotation axis (a).

[0049] The second state of the electronic device (100) may be a state in which the distance (d) between the rotation axis (a) of the second part (122) and the position (p) of the third part (123) is the maximum distance. For example, the second state may be a state in which the position (p) is closest to the rotation axis (a). For example, the second state may be a state in which the third part (123) connected to the second part (122) is expanded by the second part (122) rotating in the second rotation direction (202) with respect to the housing (110). For example, the second state may be a state in which the second part (122) is rotatable in the first rotation direction (201) with respect to the rotation axis (a).

[0050] Although the second part (122) is described as being rotatable in a first rotation direction (201) and a second rotation direction (202) opposite to the first rotation direction (201), thereby providing the first state and the second state, it is not limited thereto. The second part (122) is configured to deform the third part (123) connected to the second part (122) by being rotatable in the first rotation direction (201) and the second direction (202) opposite to the first rotation direction (201), thereby providing a plurality of states including the first state and the second state. For example, depending on the size of the wearable device (10), the second part (122) can provide intermediate states between the first state and the second state. The electronic device (100) is configured to change into a plurality of states according to the rotation of the second part (122), thereby being able to deform the third part (123) connected to the second part (122) to correspond to wearable devices (10) having various sizes.

[0051] For example, referring to FIG. 2A, the first wearable device (11) may include a first through-hole (11a) having a first size (S1) for passing a part of the user's body (e.g., a finger). The first wearable device (11) may be mounted on the housing (110) of the electronic device (100) such that the first through-hole (11a) surrounds the elastic structure (120). Since the first through-hole (11a) of the first wearable device (11) has a first size (S1) corresponding to a size of the elastic structure (120) in which the distance (d) between the rotation axis (a) and the position (p) is minimum, the third portion (123) may be brought into contact with the inner surface of the first through-hole (11a) in the first state. By the third part (123) being in contact with the inner surface of the first through hole (11a), the elastic structure (120) can increase the charging efficiency of the first wearable device (11).

[0052] For example, referring to FIG. 2B, the second wearable device (12) may include a second through hole (12a) having a second size (S2) larger than the first size (S1) for passing a part of the user's body (e.g., a finger). The second wearable device (12) may be mounted on the housing (110) of the electronic device (100) such that the second through hole (12a) surrounds the elastic structure (120). The second through hole (12a) of the second wearable device (12) may have a second size (S2) corresponding to a size of the elastic structure (120) at which the distance (d) between the rotation axis (a) and the position (p) is the largest. The second part (122) can be rotated in the second rotational direction (202) while changing from the first state to the second state in order to be deformed into the size of the elastic structure (120) corresponding to the second size (S2). The third part (123) can be deformed along the second part (122) that is rotated in the second rotational direction (202). By being deformed along the second part (122), the third part (123) can come into contact with the inner surface of the second through hole (12a) within the second state. By the third part (123) coming into contact with the inner surface of the second through hole (12a), the elastic structure (120) can increase the charging efficiency of the second wearable device (12).

[0053] Although the electronic device (100) is described as changing states for charging the first wearable device (11) and the second wearable device (12), it is not limited thereto. The electronic device (100) may be configured to change into intermediate states between the first state and the second state, thereby deforming the third portion (123) of the elastic structure (120) for charging each of a plurality of wearable devices including a through hole having a size between the first size (S1) and the second size (S2).

[0054] According to one embodiment, the first part (121) may be fastened to the housing (110) through the guide hole (111). For example, the first part (121), unlike as illustrated, may be coupled with the guide hole (111) so as to be immovable with respect to the housing (110). For example, the guide hole (111) may have a shape corresponding to the shape of the first part (121) penetrating the guide hole (111). For example, since the first part (121) is fastened to the housing (110) by the guide hole (111), the rotational axis (a) of the second part (122) may be moved by deformation of the third part (123) connecting the first part (121) and the second part (122). The electronic device (100) may require a structure in which the rotation axis (a) of the second part (122) is fixed to the housing (110) for various user experiences.

[0055] According to one embodiment, the first part (121) may be slidable along the guide hole (111) by the rotation of the second part (122). For example, the size of the first part (121) disposed within the guide hole (111) may be smaller than the size of the guide hole (111). For example, the first part (121) may be movable relative to the housing (110) along the guide hole (111). For example, the first part (121) may be movable along the guide hole (111) by the deformation of the third part (123) due to the rotation of the second part (122).

[0056] For example, the first part (121) can be configured to slide in a first direction (203) and a second direction (204) opposite to the first direction (203) by the rotation of the second part (122). For example, the third part (123) can be deformed by the second part (122) rotating in a second rotational direction (202) while changing from a first state to a second state. The third part (123) can be extended toward the wearable device (10) by the rotation of the second part (122) in the second rotational direction (202). By the deformation of the third part (123) due to the rotation of the second part (122) in the second rotational direction (202), the first part (121) can be moved in the first direction (203) along the guide hole (111). For example, the third part (123) can be deformed by the second part (122) rotating in a first rotational direction (201) opposite to the second rotational direction (202) while changing from the second state to the first state. The third part (123) can be contracted toward the rotational axis (a) of the second part (122) by the rotation of the second part (122) in the first rotational direction (201). By the deformation of the third part (123) due to the rotation of the second part (122) in the first rotational direction (201), the first part (121) can be moved in a second direction (204) opposite to the first direction (203) along the guide hole (111). However, the present invention is not limited thereto. The directions (203, 204) in which the first part (121) moves are exemplary, and the first part (121) may be configured to slide in a plurality of directions by the rotation of the second part (122). The first part (121) is configured to slide along the guide hole (111) by the rotation of the second part (122), thereby reducing damage to the elastic structure (120) by the rotation of the second part (122).

[0057] According to one embodiment, the first part (121) may be configured to fix the rotational axis (a) of the second part (122) with respect to the housing (110) by moving along the guide hole (111) by the rotation of the second part (122). For example, during the change from the first state to the second state, the first part (121) may be configured to move in the first direction (203) along the second part (122) rotating in the second rotational direction (202), thereby preventing the rotational axis (a) of the second part (122) from moving with respect to the housing (110). For example, during the change from the second state to the first state, the first part (121) can be configured to move in a second direction (204) opposite to the first direction (203) along the second part (122) that rotates in the first rotational direction (201), so that the rotational axis (a) of the second part (122) does not move with respect to the housing (110). The elastic structure (120) can be configured so that the rotational axis (a) of the second part (122) rotatable with respect to the housing (110) is fixed with respect to the housing (110), thereby reducing damage to the second part (122) due to deformation of the third part (123) and providing various user experiences to the user of the electronic device (100).

[0058] According to the above-described embodiment, the elastic structure (120) of the electronic device (100) includes a second part (122) that is rotatable with respect to the housing (110) in which the wearable device (10) is placed, and a third part (122) that is deformable by the rotation of the second part (122), thereby providing a plurality of states for charging wearable devices (10) of various sizes. The elastic structure (120) includes a first part (121) that is slidable along a guide hole (111) by the rotation of the second part (122), thereby reducing damage to the elastic structure (120) due to the rotation of the second part (122) and providing a variety of user experiences to the user.

[0059] Figure 3a is an exploded perspective view of an exemplary electronic device. Figure 3b illustrates the exemplary electronic device of Figure 3a.

[0060] Referring to FIGS. 3A and 3B, an electronic device (100) for charging a wearable device (10) may include a housing (110) including a guide hole (111), and an elastic structure (120) coupled to the housing (110) and configured to supply power to the wearable device (10). The elastic structure (120) may include a first part (121) at least partially disposed within the guide hole (111), a second part (122) rotatably coupled to the housing (110), and a third part (123) that connects the first part (121) and the second part (122) and is deformable. The third part (123) can be configured to change the distance (d) between the rotational axis (a) of the second part (122) and a position (p) of the third part (123) by being deformed by the rotation of the second part (122).

[0061] Hereinafter, redundant descriptions of configurations having the same reference numerals as those described above in FIGS. 2a and 2b are omitted.

[0062] According to one embodiment, the housing (110) may include a first frame (330), a second frame (340), and a third frame (350). For example, the first frame (330) may define a first surface (110a) on which an elastic structure (120) is disposed. For example, the first frame (330) may be a portion of the housing (110) on which a wearable device (10) is mounted. For example, the first frame (330) may be a portion in which a guide hole (111) for coupling the elastic structure (120) is formed. For example, the second frame (340) may define a third surface (110c). For example, at least one electronic component of the electronic device (100) may be disposed in the second frame (340). For example, the second frame (340) may be disposed between the first frame (330) and the third frame (350). For example, the second frame (340) may couple the first frame (330) and the third frame (350). For example, the third frame (350) may define a second surface (110b) for supporting the electronic device (100). For example, the third frame (350) may be spaced apart from the first frame (330) by the second frame (340) and may face the first frame (330). For example, the first frame (330) and the third frame (350) may cover at least a portion of the internal space of the second frame (340). However, the present invention is not limited thereto, and the housing (110) may include a plurality of frames including the frames (330, 340, 350).

[0063] According to one embodiment, the electronic device (100) may include a driving unit (310). The driving unit (310) may include a motor (311), a shaft (312), and a first gear (313) within a housing (110) for rotating a second portion (122) of an elastic structure (120). The first gear (313) may be configured to be rotated by the motor (311). The electronic device (100) may include a second gear (320) that is connected to the second portion (122) and is configured to rotate the second portion (122) by rotation of the first gear (313) by engaging with the first gear (313).

[0064] For example, the driving unit (310) may be disposed within the housing (110). For example, the driving unit (310) may be operated by receiving power from the electronic device (100). For example, the motor (311) may be configured to rotate a shaft (312) rotatably coupled to the motor (311). For example, the motor (311) may be configured to rotate a first gear (313) fastened to the shaft (312) by rotating the shaft (312). For example, the driving unit (310) may include a motor (311) that rotates the first gear (313), thereby rotating a second gear (320) meshed with the first gear (313). For example, the second gear (320) may be coupled to the second part (122). The second gear (320) can be rotated in a first rotation direction (201) and a second rotation direction (202) opposite to the first rotation direction (201) by the first gear (313) rotated by the motor (311). The second gear (320) can rotate the second part (122) of the elastic structure (120) connected to the second gear (320) by rotating in the first rotation direction (201) and the second rotation direction (202).

[0065] According to one embodiment, the housing (110) may include a hole (115) that allows at least a portion of the second portion (122) to pass therethrough. For example, the second portion (122) may include a first supporting portion (122a) that is exposed to the outside of the housing (110), and a second supporting portion (122b) that is disposed inside the housing (110). The first supporting portion (122a) may be connected to the third portion (123) of the elastic structure (120). The second supporting portion (122b) may protrude into the interior of the housing (110) through the hole (115). The second supporting portion (122b) may be fastened to a second gear (320) within the housing (110) by protruding into the interior of the housing (110) through the hole (115). The second support portion (122b) may be configured to be rotated in a first rotation direction (201) and a second rotation direction (202) opposite to the first rotation direction (201) by being engaged with the second gear (320) that is engaged with the first gear (313) that is rotated by the motor (311). Since the second support portion (122b) extends from the first support portion (122a) that is exposed to the outside of the housing (110), the first support portion (122a) may be rotated in the first rotation direction (201) and the second rotation direction (202) as the second support portion (122b) rotates. Since the first support portion (122a) is connected to the third portion (123) of the elastic structure (120), the first support portion (122a) can deform the third portion (123) as it rotates in the first rotation direction (201) and the second rotation direction (202). The elastic structure (120) can be configured to support the elastic structure (120) through the hole (115) by including the support portions (122a, 122b) and transmit the power of the motor (311) to the elastic structure (120).

[0066] According to one embodiment, the electronic device (100) may include a guide structure (130) fastened to the housing (110) to provide a rotational axis (a) of the second portion (122). The second portion (122) may include a through hole (122c) penetrated by the guide structure (130). For example, the through hole (122c) may penetrate the first support portion (122a) and the second support portion (122b). For example, the through hole (122c) may penetrate the hole (115) of the housing (110) by the second support portion (122b) penetrating the hole (115). For example, the guide structure (130) may include a support structure (131) for supporting the elastic structure (120), and a protruding structure (132) that protrudes from the support structure (131) and penetrates the through hole (122c) of the second part (122). The support structure (131) may cover at least a portion of the elastic structure (120). The protruding structure (132) may penetrate the hole (115) of the housing (110) by passing through the through hole (122c) of the second part (122). The protruding structure (132) may be coupled to at least a portion of the housing (110) (e.g., the second frame (340) and / or the third frame (350) of FIG. 3A) by passing through the hole (115) via the through hole (122c). The guide structure (130) can provide a rotational axis (a) to the second part (122) of the elastic structure (120) by being coupled to at least a portion of the housing (110) through the through hole (122c).

[0067] According to the above-described embodiment, the electronic device (100) includes a driving unit (310) including a motor (311) configured to rotate the second part (122) with respect to the housing (110), and a second gear (320), thereby providing a plurality of states for charging wearable devices (10) of various sizes. The electronic device (100) includes a guide structure (130) that provides a rotational axis (a) of the second part (122), thereby reducing the detachment of the elastic structure (120) from the housing (110) and providing a variety of user experiences to the user.

[0068] Fig. 4a is an exploded perspective view of an exemplary electronic device. Fig. 4b illustrates the exemplary electronic device of Fig. 4a.

[0069] Referring to FIGS. 4A and 4B, an electronic device (100) for charging a wearable device (10) may include a housing (110) including a guide hole (111), and an elastic structure (120) coupled to the housing (110) and configured to supply power to the wearable device (10). The elastic structure (120) may include a first part (121) at least partially disposed within the guide hole (111), a second part (122) rotatably coupled to the housing (110), and a third part (123) that connects the first part (121) and the second part (122) and is deformable. The third part (123) may be configured to change a distance (d) between a rotational axis (a) of the second part (122) and a position (p) of the third part (123) by being deformed by the rotation of the second part (122). According to one embodiment, the electronic device (100) may include a guide structure (130) fastened to the housing (110) to provide the rotational axis (a) of the second part (122). The second part (122) may include a through hole (122c) penetrated by the guide structure (130). According to one embodiment, the housing (110) may include frames (330, 340, 350). According to one embodiment, the second part (122) may include a first support part (122a), a second support part (122b), and a through hole (122c).

[0070] According to one embodiment, the elastic structure (120) may include a coil (410) for supplying power to the wearable device (10). For example, the coil (410) may be supplied with power through a power management module (e.g., a power management module (620) of FIG. 6) of the electronic device (100). For example, the coil (410) may be inserted into the third portion (123) of the elastic structure (120). For example, the coil (410) may be configured to interact with another coil (e.g., another coil (61) of FIG. 6) within the wearable device (10) so that current flows through the other coil (61). For example, the coil (410) may be placed within a portion of the third portion (123) that is relatively far away from the second portion (122) for supplying power to the wearable device (10). For example, the coil (410) may be configured to allow current to flow within the coil (410), thereby causing current to flow within another coil (61) within the wearable device (10) through electromagnetic induction with the other coil (61). The other coil (61) may be configured to charge a battery (e.g., a battery (62) of FIG. 6) within the wearable device (10) by causing current to flow through the coil (410).

[0071] According to one embodiment, the housing (110) may include a hole (115) through which at least a portion of the second portion (122) passes. The electronic device (100) may include a wheel (420) that is coupled to the second portion (122) passing through the hole (115) and rotatably coupled to the housing (110). For example, the wheel (420) may be at least partially disposed between the second frame (340) and the third frame (350) of the housing (110). For example, the wheel (420) may be coupled to the housing (110) so as to be rotatable in a first rotational direction (201) with respect to the housing (110) and a second rotational direction (202) opposite to the first rotational direction (201). For example, the second support portion (122b) of the second part (122) can be coupled to the wheel (420) by penetrating the hole (115) including the first hole (115a) penetrating the housing (110) and the second hole (115b) connected to the first hole (115a). As the wheel (420) rotates in the first rotation direction (201) and the second rotation direction (202) opposite to the first rotation direction (201), the second support portion (122b) of the second part (122) fastened to the wheel (420) can be rotated in the first rotation direction (201) and the second rotation direction (202). The second support portion (122b) extends from the first support portion (122a) which is exposed to the outside of the housing (110) and connected to the third portion (123), so that the first support portion (122a) can be rotated in the first rotation direction (201) and the second rotation direction (202) by the second support portion (122b). The elastic structure (120) can be configured to deform the third portion (123) connected to the second portion (122) by including the second portion (122) which is rotated by the rotation of the wheel (420).

[0072] According to one embodiment, the housing (110) may include a display area (430) including a plurality of display portions (431, 432, 433, 434) spaced at a specified interval and configured to provide information related to a distance (d) between a rotational axis (a) of the second portion (122) and a position (p) of the third portion (123) according to the rotation of the wheel (420). The wheel (420) may include a reference display portion (420a).

[0073] For example, the display area (430) may be formed in the third frame (350) of the housing (110). For example, the display area (430) may be exposed to the outside of the housing (110). For example, the wheel (420) may include a reference display portion (420a) configured to rotate with respect to the housing (110) along with the wheel (420) rotating with respect to the housing (110). For example, a plurality of display portions (431, 432, 433, 434) within the display area (430) may be spaced apart from each other by a specified interval, and may be respectively arranged at positions corresponding to the reference display portion (420a) rotating along the wheel (420) rotating with respect to the housing (110). The wheel (420) can deform the third part (123) of the elastic structure (120) coupled with the wheel (420) by rotating with respect to the housing (110). The electronic device (100) can provide information related to the distance (d) between the rotation axis (a) of the second part (122) and a position (p) of the third part (123) according to the rotation of the wheel (420) through the reference display part (420a) formed on the wheel (420) and the plurality of display parts (431, 432, 433, 434) formed on the housing (110). The information can include information related to the size of the wearable device (10) placed on the electronic device (100) for charging. The housing (110) includes a plurality of display units (431, 432, 433, 434), thereby providing the user with information for charging the wearable device (10) and providing the user with various user experiences.

[0074] According to the above-described embodiment, the electronic device (100) can provide multiple states for charging wearable devices (10) of various sizes by including a wheel (420) configured to rotate the second portion (122) with respect to the housing (110). The housing (110) of the electronic device (100) can provide a variety of user experiences to the user by including a display area (430) including a plurality of display portions (431, 432, 433, 434).

[0075] Figures 5a, 5b, and 5c are plan views of exemplary electronic devices.

[0076] Referring to FIGS. 5A and 5B, an electronic device (100) for charging a wearable device (10) may include a housing (110) including a guide hole (111), and an elastic structure (120) coupled to the housing (110) and configured to supply power to the wearable device (10). The elastic structure (120) may include a first part (121) at least partially disposed within the guide hole (111), a second part (122) rotatably coupled to the housing (110), and a third part (123) that connects the first part (121) and the second part (122) and is deformable. The third part (123) may be configured to change the distance (d) between the rotational axis (a) of the second part (122) and a position (e.g., a position (p) of FIG. 2a) of the third part (123) by being deformed by the rotation of the second part (122).

[0077] According to one embodiment, the third portion (123) may include a first region (123a) connected to the second portion (122) and having a radius of curvature (r1) within a first reference range (510) from the rotational axis (a) of the second portion (122), and a second region (123b) extending from the first region (123a) to the first portion (121) and having a radius of curvature (r2) within a second reference range (520) greater than the radius of curvature (r1) within the first reference range (510) from the rotational axis (a). According to one embodiment, the first region (123a) may surround at least a portion of the second portion (122). The second region (123b) may surround at least a portion of the first region (123a).

[0078] For example, the first region (123a) may be a region in which the distance (d) between the rotation axis (a) of the second part (122) and the position (p) of the third part (123) is located within the first reference range (510). For example, the first region (123a) may be a region that at least partially surrounds the second part (122) among the third part (123). For example, the first region (123a) may be a region of the third part (123) that is close to the second part (122) based on the second part (122). For example, the first region (123a) may be a region connected to the second part (122). For example, the second region (123b) may be a region located within a second reference range (520) in which the distance (d) between the rotation axis (a) of the second part (122) and a position (p) of the third part (123) is greater than the first reference range (510). For example, the second region (123b) may be a region that partially surrounds the first region (123a) of the third part (123). For example, the second region (123b) may be a region that is connected to the first part (121). For example, the first region (123a) that partially surrounds the second part (122) and the second region (123b) that partially surrounds the first region (123a) may have a spiral shape, but are not limited thereto.

[0079] According to one embodiment, the elastic structure (120) may include a coil (410) for supplying power to the wearable device (10). The coil (410) may be disposed within the second region (123b) of the third portion (123). For example, the coil (410) may be disposed within the second region (123b) of the third portion (123), thereby surrounding at least a portion of the first region (123a) of the third portion (123). For example, when the wearable device (10) is placed on the housing (110) for charging, the coil (410) may be disposed adjacent to the wearable device (10) among the second portion (122) and the wearable device (10). The coil (410) is arranged within the second region (123b), thereby increasing the charging efficiency of the wearable device (10). The coil (410) is not arranged within the first region (123a) among the first region (123a) and the second region (123b), thereby reducing the overlapping of the coil (410) according to the shape of the elastic structure (120) and reducing damage to the electronic device (100) caused by the coil (410).

[0080] For example, the wearable device (100) may include protrusions (51, 52, 53) for a sensor module within the wearable device (10), and a power supply area (10a) for charging. Within the power supply area (10a), another coil (e.g., another coil (61) of FIG. 6) for charging the wearable device (10) and a battery (e.g., a battery (62) of FIG. 6) may be arranged. Among the protrusions (51, 52, 53) of the wearable device (10), a first protrusion (51) may face the power supply area (10a). The coil (410) may be configured to be positioned within the second region (123b) of the third portion (123), so that when an angle between the central axis (X) connecting the first protrusion (51) and the power supply region (10a) and the rotational axis (a) of the second portion (122) and the fixed axis (C) connecting the coil (410) is within a range (b), the wearable device (10) may be charged through the coil (410) and the power supply region (10a). A user of the wearable device (10) may be guided to the location of the charging region (550) or the power supply region (10a) through the first protrusion (51). The above coil (410) is configured to charge the wearable device (10) even when the angle between the central axis (X) and the fixed axis (C) is within the range (b), thereby providing the user with convenience for charging the wearable device (10).

[0081] According to one embodiment, the housing (110) may include a charging region (550) in which an elastic structure (120) is disposed. For example, the charging region (550) may be a region that overlaps the elastic structure (120) when the housing (110) is viewed from above. For example, the charging region (550) may be a region of the housing (110) in which a wearable device (10) is placed. For example, the charging region (550) may be a portion that comes into contact with the wearable device (10) while the wearable device (10) is being charged through the electronic device (100). The electronic device (100) may control the elastic structure (120) so that at least a portion of the elastic structure (120) is deformed by using the charging region (550). Regarding the control of the deformation of the elastic structure (120) by the electronic device (100), this will be described later in FIG. 6.

[0082] According to the above-described embodiment, the elastic structure (120) of the electronic device (100) includes a coil (410) disposed in the second region (123b) among the first region (123a) and the second region (123b) of the third part (123), thereby reducing damage to the electronic device (100) caused by the coil (410) and increasing the charging efficiency of the wearable device (10).

[0083] Figure 6 is a block diagram of an exemplary electronic device.

[0084] Referring to FIG. 6, an electronic device (100) for charging a wearable device (10) may include a housing (e.g., the housing (110) of FIG. 1A) including a guide hole (e.g., the guide hole (111) of FIG. 1A), and an elastic structure (120) coupled to the housing (110) and configured to supply power to the wearable device (10). The elastic structure (120) may include a first part (121) at least partially disposed within the guide hole (111), a second part (122) rotatably coupled to the housing (110), and a third part (123) that connects the first part (121) and the second part (122) and is deformable. The third part (123) may be configured to change a distance (e.g., distance (d) in FIG. 2A) between a rotational axis (e.g., rotational axis (a) in FIG. 2A) of the second part (122) and a position (e.g., position (p) in FIG. 2A) of the third part (123) by being deformed by the rotation of the second part (122). According to one embodiment, the electronic device (100) may include a driving unit (310) including a motor (311) within a housing (110) for rotating the second part (122).

[0085] According to one embodiment, the electronic device (100) may further include a processor (610). The housing (110) may include a charging area (e.g., charging area (550) of FIG. 5A) in which an elastic structure (120) is disposed. The processor (610) may be configured to identify whether the elastic structure (120) is in contact with the wearable device (10) based on identifying the wearable device (10) on the charging area (550). For example, the processor (610) may be configured to identify the wearable device (10) in contact with the charging area (550).
