According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0043] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

The third pinion (435) can rotate in the opposite direction to the first pinion (431). Accordingly, as the first pinion (431) coupled to the first rack (411) and the second pinion (433) coupled to the second rack (413) rotate in opposite directions, the first rack (411) and the second rack (413) can slide in opposite directions.

[0202] According to one embodiment, when the motor (437) and the first shaft (409a) rotate in one direction, the first pinion (431) can rotate in the one direction, and the third pinion (435) can rotate in the other direction opposite to the one direction. Accordingly, the first rack (411) powerfully connected to the first pinion (431) can slide in the first slide movement direction, and the second rack (413) powerfully connected to the third pinion (435) can slide in the second slide movement direction opposite to the first slide movement direction.

[0203] According to one embodiment, the first rack (411) and the second rack (413) can slide in opposite directions according to the rotation of the motor (437). For example, when the first rack (411) slides in a direction closer to the second lens bracket (343) (e.g., the +X direction of FIGS. 5 to 12), the second rack (413) can slide in a direction closer to the first lens bracket (341) (e.g., the -X direction of FIGS. 5 to 12). For example, when the first rack (411) slides in a direction away from the second lens bracket (343) (e.g., the -X direction of FIGS. 5 to 12), the second rack (413) can slide in a direction away from the first lens bracket (341) (e.g., the +X direction of FIGS. 5 to 12).

[0204] According to one embodiment, as the first rack (411) and the second rack (413) slide in opposite directions, the first lens bracket (341) and the second lens bracket (343) can slide in opposite directions.

[0205] According to one embodiment, the first barrel (331) and the first lens coupled thereto (e.g., the first lens (221) of FIG. 3) can slide in opposite directions to the second barrel (333) and the second lens coupled thereto (e.g., the second lens (222) of FIG. 3).

[0206] In one embodiment, the first lens and the second lens can be slidably moved closer together or further apart from each other. Accordingly, the distance between the optical center of the first lens and the optical center of the second lens can be adjusted to correspond to the user's interpupillary distance (IPD).

[0207] Referring to FIG. 7, a first state in which the first lens bracket (341) and the second lens bracket (343) are relatively close is illustrated. The first lens bracket (341) and the second lens bracket (343) are illustrated in a state in which they are spaced apart by a first distance (D1).

[0208] Referring to FIG. 8, a second state is illustrated in which the first lens bracket (341) and the second lens bracket (343) are relatively far apart. The first lens bracket (341) and the second lens bracket (343) are illustrated in a state in which they are spaced apart by a second distance (D2). The second distance (D2) may be greater than the first distance (D1).

[0209] Referring to FIGS. 7 and 8, the first lens bracket (341) and the second lens bracket (343) can be slidably moved toward each other or away from each other. For example, the first lens assembly (311) and the second lens assembly (313) can be slidably moved toward each other or away from each other.

[0210] When the first lens bracket (341) and the second lens bracket (343) slide toward each other, the first barrel (331) and the second barrel (333) can slide toward each other. Accordingly, the distance between the optical center of the first lens and the optical center of the second lens can be reduced. For example, the sliding movement of the first lens bracket (341) and the second lens bracket (343) toward each other can be defined as the sliding movement in the direction in which the distance between the optical center of the first lens and the optical center of the second lens is reduced.

[0211] When the first lens bracket (341) and the second lens bracket (343) slide away from each other, the first barrel (331) and the second barrel (333) can slide away from each other. Accordingly, the distance between the optical center of the first lens and the optical center of the second lens can be expanded. For example, the sliding movement of the first lens bracket (341) and the second lens bracket (343) away from each other can be defined as the sliding movement in the direction in which the distance between the optical center of the first lens and the optical center of the second lens is expanded.

[0212] According to one embodiment, the motor (437) can receive power and signals through a connecting board (450). For example, the connecting board (450) (e.g., FPCB) can be electrically connected to a battery (e.g., battery (189) of FIG. 1) or a processor (e.g., processor (120) of FIG. 1) mounted on a circuit board (e.g., circuit board (360) of FIG. 4).

[0213] In one embodiment, the second pinion (433) may be configured to mesh with the third pinion (435) and may be spaced apart from the second rack (413). For example, the second pinion (433) may be indirectly kinetically connected to the second rack (413) via the third pinion (435).

[0214] According to one embodiment, the first shaft (409a) may be positioned at a first distance (L1) away from the third face (4131) of the second rack (413). For example, the first shaft (409a) may be positioned at a first distance (L1) away from the third face (4131) in a direction perpendicular to the third face (4131) of the second rack (413), or in a vertical direction (e.g., the Y-axis direction of FIG. 12). For example, the first shaft (409a) may be positioned at the first distance (L1) with respect to the third face (4131) (or the first face (4111)).

[0215] According to one embodiment, the second shaft (409b) may be positioned at a second distance (L2) from the third face (4131) of the second rack (413). For example, the second shaft (409b) may be positioned at a second distance (L2) from the third face (4131) in a direction perpendicular to the third face (4131) of the second rack (413), or in a vertical direction (e.g., the Y-axis direction of FIG. 12). For example, the second shaft (409b) may be positioned at a second distance (L1) with respect to the third face (4131) (or the first face (4111)). The second distance (L2) may be smaller than the first distance (L1). For example, in order to prevent interference between the second pinion (433) and the second rack (413), the first shaft (409a) may be positioned at a position spaced apart from the third face (4131) of the second rack (413) by a first distance (L1), and the second shaft (409b) may be positioned at a position spaced apart from the third face (4131) of the second rack (413) by a second distance (L2). Accordingly, a structure may be provided in which the second pinion (433) coupled to the first shaft (409a) is spaced apart from the second rack (413), and the third pinion (435) coupled to the second shaft (409b) engages with the second rack (413). In one embodiment, the third pinion (435) may have a larger diameter than the second pinion (433), and the number of gear teeth of the third pinion (435) may be greater than the number of gear teeth of the second pinion (433). In this case, even if the first shaft (409a) and the second shaft (409b) are positioned at the same distance from the third surface (4131) of the second rack (413), the second pinion (433) may be spaced apart from the second rack (413), and the third pinion (435) coupled to the second shaft (409b) may be provided with a structure that meshes with the second rack (413).

[0216] According to one embodiment, the first side (4111) of the first rack (411) may be disposed on substantially the same plane as the third side (4131) of the second rack (413). For example, the first side (4111) of the first rack (411) may form a substantially flat plane with the third side (4131) of the second rack (413).

[0217] According to one embodiment, the first pinion (431) may be configured to mesh with the first rack (411), and the second pinion (433) may be configured to be spaced apart from the second rack (413).

[0218] In one embodiment, the first pinion (431) and the second pinion (433) are arranged on the first shaft (409a), so that the first rack (411) can have a greater thickness than the second rack (413) to mesh with the first pinion (431).

[0219] In one embodiment, the first rack (411) may have a first thickness (t1) from the first side (4111) to the second side (4112), and the second rack (413) may have a second thickness (t2) from the third side (4131) to the fourth side (4132). In one embodiment, the first thickness (t1) may be greater than the second thickness (t2). In one embodiment, the first pinion (431) may have a larger diameter than the second pinion (433). In such a case, even if the first thickness (t1) is substantially the same as the second thickness (t2), or the first thickness (t1) is smaller than the second thickness (t2), the first pinion (431) may be configured to mesh with the first rack (411), and the second pinion (433) may be provided with a structure spaced apart from the second rack (413).

[0220] According to one embodiment, the third pinion (435) may be arranged on one side of the second pinion (431). For example, the third pinion (435) may be arranged on the side in which the optical center of the first lens and the optical center of the second lens are reduced (e.g., the -X direction in FIG. 9) among the sliding movement directions of the second rack (413) with respect to the second pinion (433). For example, the second pinion (435) may be arranged closer to the 2-2 hole (413b) than to the 2-1 hole (413a).

[0221] In one embodiment, the second rack (413), the second pinion (433), and the third pinion (435) may be positioned relatively farther away from the motor (437) than the first rack (411) and the first pinion (431).

[0222] According to one embodiment, the first face (4111) (or the second face (4112)) of the first rack (411) and / or the third face (4131) (or the fourth face (4132)) of the second rack (413) may face a direction toward which the wearable electronic device (201) is directed (e.g., the +Y direction of FIGS. 2 to 12) and / or a direction toward a user (e.g., the -Y direction of FIGS. 2 to 12). Accordingly, the first shaft (409a) connected to the motor (437) may extend in a direction substantially perpendicular to the direction toward which the wearable electronic device (201) is directed and the direction toward the user (e.g., the Z-axis direction of FIGS. 2 to 12). For example, the axial direction of the first shaft (409a) (e.g., the Z-axis direction of FIGS. 9 to 12) may be substantially perpendicular to the direction in which the wearable electronic device (201) is directed and the direction toward the user. For example, the axial direction of the first shaft (409a) may be substantially perpendicular to the thickness direction (e.g., the Y-axis direction of FIGS. 2 to 12) of the first housing (e.g., the first housing (202) of FIGS. 2 to 3 or the first housing (310) of FIG. 4). The axial direction of the first shaft may be substantially the same direction as the height direction (or, up-down direction) of the first housing (e.g., the Z-axis direction of FIGS. 2 to 12). Accordingly, as the first shaft (409a) extends in the height direction of the first housing, the first shaft (409a) and the motor (437) can occupy a relatively small area in the thickness direction of the first housing (e.g., the Y-axis direction of FIGS. 2 to 12) inside the first housing, compared to a case where the axial direction of the first shaft extends or is positioned in the thickness direction of the first housing (e.g., the Y-axis direction of FIGS. 2 to 12).Accordingly, the thickness in the thickness direction of the first housing for accommodating the first shaft (409a) and the motor (437) (e.g., the thickness in the Z-axis direction of FIGS. 2 to 12) can be relatively smaller compared to the case where the axial direction of the first shaft extends or is positioned in the thickness direction of the first housing (e.g., the Y-axis direction of FIGS. 2 to 12). In addition, since the driving structure (400) including the first shaft (409a) and the motor (437) is arranged in the mounting portion (3029) formed in the connecting member (3027) for connecting the first frame member (3022) and the second frame member (3024), the space utilization of the first housing is improved, so that the overall size of the wearable electronic device (201) can be miniaturized.

[0224] FIG. 14 is a side view showing a driving structure according to one embodiment of the present disclosure.

The second side (4112) may face a direction that faces the user (e.g., the -Y direction of FIGS. 2 to 3 , or the -Y direction of FIGS. 13 to 16 ). According to one embodiment, the first side (4111) may face a direction that faces the user (e.g., the -Y direction of FIGS. 2 to 3 , or the -Y direction of FIGS. 13 to 16 ), and the second side (4112) may face a direction that a user looks at, or a direction that the wearable electronic device (201) is directed toward (e.g., the +Y direction of FIGS. 2 to 3 , or the +Y direction of FIGS. 13 to 16 ).

[0256] According to one embodiment, the first shaft (409a) may be connected to a motor (437) and may rotate based on the rotation of the motor (437). The first shaft (409a) may also be defined as a part of the motor (437).

[0257] In one embodiment, the second shaft (409b) may be spaced apart from the first shaft (409a) and rotatably coupled to the bracket (420). For example, the bracket (420) may rotatably support the second shaft (409b).

[0258] Referring to FIG. 13, a virtual first line (401) drawn along the extension direction (or axial direction) of the first shaft (409a) and a virtual second line (402) drawn along the extension direction (or axial direction) of the second shaft (409b) are illustrated. The first line (401) may be spaced apart from the second line (402). The distance by which the second line (402) is spaced apart from the first line (401) may be defined as the distance by which the center of the axis of the second shaft (409b) is spaced apart from the center of the axis of the first shaft (409a). The distance by which the second line (402) is spaced apart from the first line (401) may be determined by the first pinion (431) and the third pinion (436). For example, the sum of the radii of the first pinion (431) and the radii of the third pinion (436) may be defined as the distance by which the center of the axis of the second shaft (409b) is spaced relative to the center of the axis of the first shaft (409a). For example, if the diameters of the first pinion (431) and the diameters of the third pinion (436) are substantially in a 1:1 relationship, the diameter of the first pinion (431) (or the third pinion (436)) may be substantially equal to the distance by which the second line (402) is spaced relative to the first line (401). The distance by which the second line (402) is spaced relative to the first line (401) may be defined as the amount of movement (or the distance of movement) relative to the center line of the motor (437).

[0259] In one embodiment, the first pinion (431) and / or the second pinion (433) may be coupled to the first shaft (409a). For example, the first pinion (431) and / or the second pinion (433) may be disposed on the first line (401). The first pinion (431) may be spaced apart from the second pinion (433) on the first line (401).

[0260] In one embodiment, the first pinion (431) may be configured to mesh with a third pinion (436). The third pinion (436) may be configured to mesh with second gear teeth (414) of the second rack (413).

[0261] In one embodiment, the third pinion (436) may be coupled to the second shaft (409b). For example, the third pinion (436) may be disposed on the second line (402).

[0262] In one embodiment, at least a portion of the third pinion (436) may be configured to mesh with second gear teeth (414) of the second rack (413). Another portion of the third pinion (436) may be configured to mesh with the first pinion (431).

[0263] According to one embodiment, the first pinion (431) and / or the second pinion (433) may be rotated together with the first shaft (409a) according to the rotation of the first shaft (409a).

[0264] According to one embodiment, the second rack (413) can slide on the bracket (420) based on the rotation of the third pinion (436).

[0265] In one embodiment, the third pinion (436) can be rotated in the opposite direction to the first pinion (431) based on the rotation of the first pinion (431).

[0266] According to one embodiment, the second rack (413) can slide on the bracket (420) based on the rotation of the third pinion (436).

[0267] In one embodiment, the first pinion (431) can rotate in the same direction as the second pinion (433), and the third pinion (436) can rotate in the opposite direction to the first pinion (431). The third pinion (436) can rotate in the opposite direction to the second pinion (433). Accordingly, as the second pinion (433) coupled to the first rack (411) and the third pinion (436) coupled to the second rack (413) rotate in opposite directions, the first rack (411) and the second rack (413) can slide in opposite directions.

[0268] According to one embodiment, when the motor (437) and the first shaft (409a) are rotated in one direction, the second pinion (433) can be rotated in the one direction, and the third pinion (436) can be rotated in the other direction opposite to the one direction. Accordingly, the first rack (411) powerfully connected to the second pinion (433) can be slidably moved in the first slide movement direction, and the second rack (413) powerfully connected to the third pinion (436) can be slidably moved in the second slide movement direction opposite to the first slide movement direction.

[0269] According to one embodiment, the first rack (411) and the second rack (413) can slide in opposite directions according to the rotation of the motor (437). For example, when the first rack (411) slides in a direction (e.g., the +X direction of FIGS. 13 to 16) toward the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8), the second rack (413) can slide in a direction (e.g., the -X direction of FIGS. 13 to 16) toward the first lens bracket (e.g., the first lens bracket (341) of FIGS. 5 to 8). For example, when the first rack (411) slides away from the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8) in a direction (e.g., the -X direction of FIGS. 13 to 16), the second rack (413) can slide away from the first lens bracket (e.g., the first lens bracket (341) of FIGS. 13 to 16) in a direction (e.g., the +X direction of FIGS. 5 to 13).

[0270] According to one embodiment, as the first rack (411) and the second rack (413) slide in opposite directions, the first lens bracket (e.g., the first lens bracket (341) of FIGS. 5 to 8) and the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8) can slide in opposite directions.

[0271] According to one embodiment, a first barrel (e.g., a first barrel (331) of FIG. 5) and a first lens coupled thereto (e.g., a first lens (221) of FIG. 3) can slide in opposite directions to a second barrel (e.g., a second barrel (333) of FIG. 5) and a second lens coupled thereto (e.g., a second lens (222) of FIG. 3).

[0272] In one embodiment, the first lens and the second lens can be slidably moved closer together or further apart from each other. Accordingly, the distance between the optical center of the first lens and the optical center of the second lens can be adjusted to correspond to the user's interpupillary distance (IPD).

[0273] When the first lens bracket (e.g., the first lens bracket (341) of FIGS. 5 to 8) and the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8) slide toward each other, the first optical tube (e.g., the first optical tube (331) of FIG. 5) and the second optical tube (e.g., the second optical tube (333) of FIG. 5) can slide toward each other. Accordingly, the distance between the optical center of the first lens and the optical center of the second lens can be reduced. For example, the sliding movement of the first lens bracket (e.g., the first lens bracket (341) of FIGS. 5 to 8) and the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8) toward each other can be defined as the sliding movement in the direction in which the distance between the optical center of the first lens and the optical center of the second lens is reduced.

[0274] When the first lens bracket (e.g., the first lens bracket (341) of FIGS. 5 to 8) and the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8) slide away from each other, the first optical tube (e.g., the first optical tube (331) of FIG. 5) and the second optical tube (e.g., the second optical tube (333) of FIG. 5) can slide away from each other. Accordingly, the distance between the optical center of the first lens and the optical center of the second lens can be expanded. For example, the sliding movement of the first lens bracket (e.g., the first lens bracket (341) of FIGS. 5 to 8) and the second lens bracket (e.g., the second lens bracket (343) of FIGS. 5 to 8) away from each other can be defined as the sliding movement in the direction in which the distance between the optical center of the first lens and the optical center of the second lens is expanded.

[0275] According to one embodiment, the motor (437) can receive power and signals through a connecting board (450). For example, the connecting board (450) (e.g., FPCB) can be electrically connected to a battery (e.g., battery (189) of FIG. 1) or a processor (e.g., processor (120) of FIG. 1) mounted on a circuit board (e.g., circuit board (360) of FIG. 4).

[0276] In one embodiment, the first pinion (431) may be configured to mesh with the third pinion (436) and may be spaced apart from the second rack (413). For example, the first pinion (431) may be indirectly kinetically connected to the second rack (413) via the third pinion (436).

[0277] According to one embodiment, the first shaft (409a) may be positioned at a first distance (L1) away from the third face (4131) of the second rack (413). For example, the first shaft (409a) may be positioned at a first distance (L1) away from the third face (4131) in a direction perpendicular to the third face (4131) of the second rack (413), or in a vertical direction (e.g., the Y-axis direction of FIG. 12). For example, the first shaft (409a) may be positioned at the first distance (L1) with respect to the third face (4131) (or the first face (4111)).

[0278] According to one embodiment, the second shaft (409b) may be positioned at a second distance (L2) from the third face (4131) of the second rack (413). For example, the second shaft (409b) may be positioned at a second distance (L2) from the third face (4131) in a direction perpendicular to the third face (4131) of the second rack (413), or in a vertical direction (e.g., the Y-axis direction of FIG. 16). For example, the second shaft (409b) may be positioned at a second distance (L1) with respect to the third face (4131) (or the first face (4111)). The second distance (L2) may be smaller than the first distance (L1). For example, in order to prevent interference between the first pinion (431) and the second rack (413), the first shaft (409a) may be positioned at a position spaced apart from the third face (4131) of the second rack (413) by a first distance (L1), and the second shaft (409b) may be positioned at a position spaced apart from the third face (4131) of the second rack (413) by a second distance (L2). Accordingly, a structure may be provided in which the first pinion (431) coupled to the first shaft (409a) is spaced apart from the second rack (413), and the third pinion (436) coupled to the second shaft (409b) engages with the second rack (413). In one embodiment, the third pinion (436) may have a larger diameter than the first pinion (431), and the number of gear teeth of the third pinion (436) may be greater than the number of gear teeth of the first pinion (431). In this case, even if the first shaft (409a) and the second shaft (409b) are positioned at the same distance from the third surface (4131) of the second rack (413), the first pinion (431) may be spaced apart from the second rack (413), and the third pinion (436) coupled to the second shaft (409b) may be provided with a structure that meshes with the second rack (413).

[0279] According to one embodiment, the first side (4111) of the first rack (411) may be disposed on substantially the same plane as the third side (4131) of the second rack (413). For example, the first side (4111) of the first rack (411) may form a substantially flat plane with the third side (4131) of the second rack (413).

[0280] In one embodiment, the second pinion (433) may be configured to mesh with the first rack (411), and the first pinion (431) may be configured to be spaced apart from the second rack (413).

[0281] In one embodiment, the second pinion (433) and the first pinion (431) are arranged on the first shaft (409a), so that the first rack (411) can have a greater thickness than the second rack (413) to mesh with the second pinion (433).

[0282] In one embodiment, the first rack (411) may have a first thickness (t1) from the first side (4111) to the second side (4112), and the second rack (413) may have a second thickness (t2) from the third side (4131) to the fourth side (4132). In one embodiment, the first thickness (t1) may be greater than the second thickness (t2). In one embodiment, the second pinion (433) may have a larger diameter than the first pinion (431). In such a case, even if the first thickness (t1) is substantially the same as the second thickness (t2), or the first thickness (t1) is smaller than the second thickness (t2), the second pinion (433) may be configured to mesh with the first rack (411), and the first pinion (431) may be provided with a structure spaced apart from the second rack (413).

[0283] According to one embodiment, the third pinion (436) may be arranged on one side of the first pinion (431). For example, the third pinion (436) may be arranged on the side in which the optical center of the first lens and the optical center of the second lens expand (e.g., the +X direction in FIG. 13) among the sliding movement directions of the second rack (413) with respect to the first pinion (431). For example, the third pinion (436) may be arranged closer to the 2-1 hole (413a) than to the 2-2 hole (413b).

[0284] In one embodiment, the first rack (411) and the second pinion (433) may be positioned relatively farther apart from the motor (437) than the second rack (413), the first pinion (431), and the third pinion (436).

[0285] According to one embodiment, the first face (4111) (or the second face (4112)) of the first rack (411) and / or the third face (4131) (or the fourth face (4132)) of the second rack (413) may face a direction in which a wearable electronic device (e.g., the wearable electronic device (201) of FIGS. 2 to 5) is directed (e.g., the +Y direction of FIGS. 2 to 8 or FIGS. 13 to 16) and / or a direction toward a user (e.g., the -Y direction of FIGS. 2 to 8 or FIGS. 13 to 16). Accordingly, the first shaft (409a) connected to the motor (437) may extend in a direction substantially perpendicular to the direction in which the wearable electronic device is directed and the direction toward the user (e.g., the Z-axis direction of FIGS. 2 to 8 or FIGS. 13 to 16). For example, the axial direction of the first shaft (409a) (e.g., the Z-axis direction of FIGS. 13 to 16) may be substantially perpendicular to the direction in which the wearable electronic device is directed and the direction toward the user. For example, the axial direction of the first shaft (409a) may be substantially perpendicular to the thickness direction (e.g., the Y-axis direction of FIGS. 2 to 8 or FIGS. 13 to 16) of the first housing (e.g., the first housing (202) of FIGS. 2 to 3 or the first housing (310) of FIG. 4). The axial direction of the first shaft may be substantially the same direction as the height direction (or the up-down direction) of the first housing (e.g., the Z-axis direction of FIGS. 2 to 8 or FIGS. 13 to 16).Accordingly, as the first shaft (409a) extends in the height direction of the first housing, the first shaft (409a) and the motor (437) can occupy a relatively small area in the thickness direction of the first housing (e.g., the Y-axis direction of FIGS. 2 to 8 or FIGS. 13 to 16) inside the first housing, compared to a case where the axial direction of the first shaft extends or is positioned in the thickness direction of the first housing (e.g., the Y-axis direction of FIGS. 2 to 8 or FIGS. 13 to 16). Accordingly, the thickness in the thickness direction of the first housing for accommodating the first shaft (409a) and the motor (437) (e.g., the thickness in the Z-axis direction of FIGS. 2 to 12) can be relatively smaller compared to the case where the axial direction of the first shaft is extended or positioned in the thickness direction of the first housing (e.g., the Y-axis direction of FIGS. 2 to 8 or FIGS. 13 to 16). In addition, since the driving structure (400) including the first shaft (409a) and the motor (437) is arranged on the mounting portion (e.g., mounting portion (3029) of FIG. 5) formed on the connecting member (e.g., connecting member (3027) of FIG. 5) for connecting the first frame member (e.g., the first frame member (3022) of FIG. 5) and the second frame member (e.g., the first frame member (3024) of FIG. 5), the space utilization of the first housing is improved, and the overall size of the wearable electronic device (e.g., the wearable electronic device (201) of FIGS. 2 to 5) can be miniaturized.

[0286] A wearable electronic device may include a display module that provides visual images to a user. The display module may provide visual images to the user through a pair of lenses corresponding to the user's left and right eyes.

[0287] In order to improve the quality of visual images of a VR environment or AR environment provided to a user, the distance between the optical centers of each pair of lenses is required to correspond to, or be substantially equal to, the inter-pupillary distance (IPD) of the user.

[0288] Depending on individual characteristics or the user's body type, the distance between the pupils of each user may vary, and accordingly, a wearable electronic device in which the distance between the optical centers of a pair of lenses can be adjusted is required.

[0289] According to one embodiment of the present disclosure, a drive structure capable of adjusting the distance between the optical center of a first lens and the optical center of a second lens and a wearable electronic device including the same can be provided.

[0290] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

[0291] According to one embodiment of the present disclosure, a driving structure and an electronic device including the same can be provided that can move in a direction in which the distance between the optical center of a first lens and the optical center of a second lens is expanded or reduced through one motor.
