[0040] The configuration of the electronic device (100) of FIGS. 1 and 2 may be referenced by the configuration of other drawings. The same terms and / or the same reference numerals are used for configurations that are identical or substantially identical to those of other drawings.

[0041] According to one embodiment, the electronic device (100) may include various components. For example, the electronic device (100) may include at least one of a housing (e.g., a foldable housing), a display (130), a hinge cover (140), or an input member (150). However, the configuration of the electronic device (100) is not limited to the above-described configuration. For example, the electronic device (100) may omit at least one of the above-described configurations, or may further include at least one configuration. For example, the electronic device (100) may include at least one of a hinge assembly, a printed circuit board, or a battery. According to one embodiment, the housing may include a first housing (110) and a second housing (120). However, the configuration is not limited thereto. For example, the housing may further include one or more housings.

[0042] According to one embodiment, the first housing (110) and the second housing (120) may form the exterior of the electronic device (100). For example, the first housing (110) and the second housing (120) may form at least one of at least a portion of the front side, at least a portion of the back side, or at least a portion of the side side of the electronic device (100). In one embodiment, at least one of the first housing (110) or the second housing (120) may include a conductive material (e.g., metal).

[0043] According to one embodiment, the display (130) may be disposed in at least one of the first housing (110) or the second housing (120). For example, the display (130) may be disposed in the first housing (110). For example, referring to FIG. 1, the display (130) may be disposed in the first side (or, first surface) (111) of the first housing (110). In one example, the display (130) may be seated in a recess formed by the first housing (110). However, the arrangement of the display (130) is not limited to that illustrated in FIG. 1. For example, the display (130) may be disposed in the first housing (110) and the second housing (120). For example, the display (130) may be disposed on a first side (111) of the first housing (110) and a first side (e.g., first surface) (121) of the second housing (120). For example, the display (130) may include a flexible display disposed across the first housing (110) and the second housing (120).

[0044] According to one embodiment, the input member (150) may be disposed in at least one of the first housing (110) or the second housing (120). For example, the input member (150) may be disposed in the second housing (120). For example, referring to FIG. 1, the input member (150) may be disposed on the first side (121) of the second housing (120). However, the arrangement of the input member (150) is not limited to that illustrated in FIG. 1. For example, the input member (150) may be disposed in the first housing (110) and the second housing (120). In one example, the input member (150) may include at least one of a keyboard or a touch pad.

[0045] According to one embodiment, at least one of the first housing (110) or the second housing (120) may be provided with a power connector for connecting an external power source or a slot for mounting a storage medium or external memory.

[0046] According to one embodiment, the first housing (110) and the second housing (120) may be rotatably connected to each other. For example, the first housing (110) and the second housing (120) may be rotatably coupled to each other. For example, the first housing (110) and the second housing (120) may be rotatably coupled to each other through at least one hinge assembly (e.g., the hinge assembly (200, 300) of FIG. 3). According to one embodiment, the hinge cover (140) may cover the hinge assembly. It may be disposed between the first housing (110) and the second housing (120).

[0047] According to one embodiment, the electronic device (100) may have an unfolded state, a folded state, and / or an intermediate state.

[0048] In one embodiment, the unfolded state may include a state in which at least a portion of the housing is unfolded. For example, the unfolded state may include a state in which the first housing (110) and the second housing (120) are arranged at a 180-degree angle. For example, the unfolded state may include a state in which the first side (111) of the first housing (110) is arranged in the same direction as the first side (121) of the second housing (120).

[0049] In one embodiment, the folded state may include a state in which the housing is folded. For example, the folded state may include a state in which the first housing (110) and the second housing (120) are arranged to face each other. For example, the folded state may include a state in which the first side (111) of the first housing (110) and the first side (121) of the second housing (120) are arranged to face each other. For example, the folded state may include a state in which the first side (111) of the first housing (110) and the first side (121) of the second housing (120) are arranged to face each other in opposite directions. For example, the folded state may include a state in which the first housing (110) and the second housing (120) form a narrow angle (e.g., between 0 and 10 degrees) with each other and face each other. However, the present invention is not limited thereto. For example, the folded state may include a state in which a second side (112) opposite the first side (111) of the first housing (110) and a second side (not shown) opposite the first side (121) of the second housing (120) are arranged to face each other.

[0050] In one embodiment, the intermediate state may include a state in which the first housing (110) and the second housing (120) are arranged at a certain angle with respect to each other. However, the specific angles formed by the first housing (110) and the second housing (120) in the unfolded state, the folded state, and the intermediate state are for convenience of explanation and are not limited thereto.

[0051] According to one embodiment, the display (130) may include a flexible display arranged across the first housing (110) and the second housing (120). The flexible display may be mounted on a recess formed by the first housing (110) and the second housing (120). In one embodiment, the flexible display may include a first region and a second region. The first region and the second region of the flexible display may be divided around an axis (e.g., a rotation axis) that serves as a reference for folding or unfolding the electronic device (100). For example, the flexible display may be divided into a folding region having a predetermined curvature when the electronic device (100) is folded around the axis, a first region adjacent to the first housing (110) based on the folding region, and a second region adjacent to the second housing (120) based on the folding region. In one example, the first region and the second region may have a shape that is symmetrical overall about the axis, but is not limited thereto.

[0052] According to one embodiment, the arrangement structure of the first region and the second region of the flexible display may vary depending on the state of the electronic device (100). In one example, when the electronic device (100) is in an unfolded state, the first region and the second region of the flexible display may form a 180 degree angle with respect to each other. In one example, when the electronic device (100) is in a folded state, the first region and the second region of the flexible display may form a narrow angle (e.g., between 0 and 10 degrees) with respect to each other and may face each other. However, the present invention is not limited thereto. For example, when the electronic device (100) is in a folded state, the first region and the second region of the flexible display may form a narrow angle (e.g., between 0 and 10 degrees) with respect to each other and may be arranged to face in opposite directions. In one example, when the electronic device (100) is in an intermediate state, the first region and the second region of the flexible display may form an angle that is greater than the folded state and less than the unfolded state. For example, the flexible display may be formed of a curved surface having at least a portion of a predetermined curvature, and the curvature at this time may be less than that when the flexible display is in a folded state. However, the specific angles formed by the first region and the second region in the unfolded state, folded state, and intermediate state described above are for convenience of explanation and are not limited thereto.

[0053] FIG. 3 is a drawing illustrating a hinge assembly arranged in an electronic device according to one embodiment.

[0054] The configuration of FIG. 3 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0055] Referring to FIG. 3, an electronic device (100) according to an embodiment may include at least one hinge assembly (200, 300) that rotatably connects a first housing (e.g., the first housing (110) of FIG. 1) and a second housing (e.g., the second housing (120) of FIG. 1) with respect to each other. In one example, the electronic device (100) may include a plurality of hinge assemblies (200, 300). However, the number of hinge assemblies is not limited to that illustrated in FIG. 3. According to one embodiment, the hinge assemblies (200, 300) may be disposed between the first housing and the second housing.

[0056] According to one embodiment, the hinge assembly (200, 300) may be positioned adjacent to a first side (101) of the electronic device (100) and a second side (102) opposite the first side (101). For example, the hinge assembly (200) may be positioned adjacent to the second side (102) of the electronic device (100). For example, the hinge assembly (300) may be positioned adjacent to the first side (101) of the electronic device (100).

[0057] According to one embodiment, the hinge assembly (200, 300) can rotate about a rotation axis (e.g., rotation axis RX of FIG. 5) that faces in a direction from the first side (101) to the second side (102) of the electronic device (100). For example, the hinge assembly (200, 300) can rotate about a rotation axis that faces the y-axis direction. When the hinge assembly (200, 300) rotates about the rotation axis, the state of the electronic device (100) can change. For example, when the hinge assembly (200, 300) rotates about the rotation axis, the state of the electronic device (100) can be one of a folded state, an unfolded state, and an intermediate state.

[0058] Figure 4 is a perspective view of a hinge assembly according to one embodiment.

[0059] The configuration of FIG. 4 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or reference numerals are used, and redundant descriptions are omitted.

[0060] Referring to FIG. 4, a hinge assembly (200) according to one embodiment may include a first shaft (210), a first bracket (220), a second shaft (230), and a second bracket (240). However, the configuration of the hinge assembly (200) is not limited thereto. For example, the hinge assembly (200) may omit at least one of the above-described configurations, or may further include at least one configuration. For example, the hinge assembly (200) may further include a first fixing member (for example, the first fixing member (270) of FIG. 5).

[0061] According to one embodiment, the hinge assembly (200) may include a plurality of hinge assemblies to generate frictional torques of various values. For example, the hinge assembly (200) may include a first hinge assembly (200a) that generates a frictional torque having a first value, and a second hinge assembly (200b) that generates a frictional torque having a second value. In one example, the first value may be different from the second value.

[0062] According to one embodiment, the hinge assembly (200) may further include at least one hinge assembly to generate a friction torque having an appropriate value, or may omit at least one hinge assembly. For example, the hinge assembly (200) may further include at least one hinge assembly to generate a larger friction torque, or may omit at least one hinge assembly to generate a smaller friction torque. For example, the hinge assembly (200) may further be coupled with at least one hinge assembly, or may be separated from at least one hinge assembly included in the hinge assembly (200).

[0063] According to one embodiment, when the hinge assembly (200) is further coupled with at least one hinge assembly, the value of the frictional torque generated by the hinge assembly (200) may increase. When the hinge assembly (200) is separated from at least one hinge assembly, the value of the frictional torque generated by the hinge assembly (200) may decrease. For example, the hinge assembly (200) may include a first hinge assembly (200a) that generates a frictional torque having a first value, and a second hinge assembly (200b) that generates a frictional torque having a second value, thereby generating a frictional torque having a third value. In one example, the third value may be a sum of the first value and the second value. However, the present invention is not limited thereto.

[0064] In the present disclosure, for convenience of explanation, the hinge assembly (200) is illustrated and described as including two hinge assemblies, but the number of hinge assemblies included in the hinge assembly (200) is not limited thereto. In the present disclosure, the content regarding one or more hinge assemblies (e.g., a third hinge assembly) further coupled to the hinge assembly (200) may be referenced by the content regarding the second hinge assembly (200a).

[0065] According to one embodiment, the first hinge assembly (200a) may include a first shaft (210) and a first bracket (220). The first shaft (210) and the first bracket (220) may rotate with respect to each other. For example, the first shaft (210) may rotate with respect to the first bracket (220). The first bracket (220) may rotate with respect to the first shaft (210). When the first shaft (210) and the first bracket (220) rotate with respect to each other, the first shaft (210) and the first bracket (220) may generate a frictional torque. For example, the first shaft (210) and the first bracket (220) may generate a frictional torque having a first value.

[0066] According to one embodiment, the second hinge assembly (200b) may include a second shaft (230) and a second bracket (240). The second shaft (230) and the second bracket (240) may rotate with respect to each other. For example, the second shaft (230) may rotate with respect to the second bracket (240). The second bracket (240) may rotate with respect to the second shaft (230). When the second shaft (230) and the second bracket (240) rotate with respect to each other, the second shaft (230) and the second bracket (240) may generate a frictional torque. For example, the second shaft (230) and the second bracket (240) may generate a frictional torque having a second value.

[0067] In one embodiment, when the second shaft (230) and the first shaft (210) are coupled, the second shaft (230) can rotate together with the first shaft (210). For example, the second shaft (230) can share the same rotational axis as the first shaft (210). In one embodiment, the second shaft (230) can rotate to the same degree as the first shaft (210) rotates. For example, the second shaft (230) can rotate about the rotational axis by an angle that the first shaft (210) rotates about the rotational axis.

[0068] In one embodiment, when the second shaft (230) and the first shaft (210) are coupled, the second bracket (240) can rotate together with the first bracket (220). For example, the second bracket (240) can share the same rotational axis as the first bracket (220). In one embodiment, the second bracket (240) can rotate by the same degree as the first bracket (220) rotates. For example, the second bracket (240) can rotate about the rotational axis by an angle that the first bracket (220) rotates about the rotational axis.

[0070] The configuration of FIG. 5 may be referenced by the configuration of other drawings. The same terminology and / or the same reference numerals are used for configurations that are identical or substantially identical to those of other drawings.

[0071] Referring to FIG. 5, a hinge assembly (200) according to one embodiment may include a first shaft (210), a first bracket (220), a second shaft (230), and a second bracket (240). However, the configuration of the hinge assembly (200) is not limited thereto. For example, the hinge assembly (200) may omit at least one of the above-described configurations, or may further include at least one configuration. For example, the hinge assembly (200) may further include at least one of the first fixing member (270), the second fixing member (250), or the third fixing member (260).

[0072] According to one embodiment, the first shaft (210) may include a first protrusion (212). The first protrusion (212) may protrude in a direction in which the rotational axis (RX) of the hinge assembly (200) faces. In one example, a longitudinal direction of the first protrusion (212) may be substantially parallel to a direction in which the rotational axis (RX) faces. In one example, a longitudinal direction of the first protrusion (212) may be substantially parallel to a longitudinal direction of the hinge assembly (200).

[0073] In one embodiment, the first shaft (210) can rotate about a rotational axis (RX). For example, the first protrusion (212) can rotate about the rotational axis (RX). In one example, the first shaft (210) can provide the rotational axis (RX) to the hinge assembly (200). For example, the first protrusion (212) can provide the rotational axis (RX) to the hinge assembly (200). For example, the first protrusion (212) can provide the rotational axis (RX) to the first shaft (210). In one example, the hinge assembly (200) can rotate about an axis passing through the center of the first protrusion (212). For example, the first shaft (210) can rotate about an axis passing through the center of the first protrusion (212). For example, the first protrusion (212) can rotate about an axis passing through the center of the first protrusion (212).

[0074] According to one embodiment, the first protrusion (212) may have a cylindrical shape. For example, the cross-section of the first protrusion (212) may have a circular shape. In the present disclosure, the length (R1) of the outer diameter of the first protrusion (212) may include the diameter of the cross-section of the first protrusion (212).

[0075] In one embodiment, the first bracket (220) can accommodate a portion of the first shaft (210) (e.g., the first protrusion (212)). For example, a portion of the first shaft (210) can be positioned within the first bracket (220). For example, a portion of the first bracket (220) can surround a portion of the first shaft (210). For example, a portion of the first shaft (210) can penetrate the first bracket (220).

[0076] According to one embodiment, the first bracket (220) can rotate about the first shaft (210). For example, the first bracket (220) can rotate about the rotational axis (RX) of the hinge assembly (200) about the first shaft (210). For example, the first bracket (220) can rotate about the rotational axis (RX) about the first protrusion (212).

[0077] In one embodiment, the first shaft (210) can rotate with respect to the first bracket (220). For example, the first shaft (210) can rotate about the rotational axis (RX) of the hinge assembly (200) with respect to the first bracket (220). For example, the first protrusion (212) can rotate about the rotational axis (RX) with respect to the first bracket (220).

[0078] According to one embodiment, when the first shaft (210) and the first bracket (220) rotate with respect to each other, the first protrusion (212) of the first shaft (210) and the first bracket (220) can generate frictional torque.

[0079] According to one embodiment, the second fixing member (250) may be coupled with the first shaft (210). By coupling the second fixing member (250) with the first shaft (210), the first bracket (220) may not be separated from the first shaft (210). For example, the second fixing member (250) may prevent the first bracket (220) from being separated from the first shaft (210) in the direction in which the rotation axis (RX) faces.

[0080] According to one embodiment, the second shaft (230) may include a second protrusion (232). The second protrusion (232) may protrude in a direction in which the rotational axis (RX) of the hinge assembly (200) faces. In one example, a longitudinal direction of the second protrusion (232) may be substantially parallel to the direction in which the rotational axis (RX) faces. In one example, a longitudinal direction of the second protrusion (232) may be substantially parallel to a longitudinal direction of the hinge assembly (200). In one example, a longitudinal direction of the second protrusion (232) may be substantially parallel to a longitudinal direction of the first protrusion (212).

[0081] In one embodiment, the second shaft (230) can rotate about an axis of rotation (RX). For example, the second protrusion (232) can provide the axis of rotation (RX) to the second shaft (230). For example, the second shaft (230) can rotate about an axis passing through the center of the second protrusion (232). In one example, the hinge assembly (200) can rotate about an axis passing through the center of the second protrusion (232). For example, the hinge assembly (200) can rotate about an axis passing through the center of the first protrusion (212) and the center of the second protrusion (232).

[0082] According to one embodiment, the second protrusion (232) may have a cylindrical shape. For example, the cross-section of the second protrusion (232) may have a circular shape. In the present disclosure, the length (R2) of the outer diameter of the second protrusion (232) may include the diameter of the cross-section of the second protrusion (232).

[0083] In one embodiment, the second shaft (230) may be coupled to the first shaft (210) so as to rotate together with the first shaft (210). For example, the first shaft (210) and the second shaft (230) may share a rotation axis (RX). For example, the first protrusion (212) and the second protrusion (232) may share a rotation axis (RX).

[0084] According to one embodiment, the second shaft (230) may be fixed to the first shaft (210) by the first fixing member (270). For example, the second shaft (230) may be fixed to the first shaft (210) by the first fixing member (270) so that when the first shaft (210) rotates, the second shaft (230) may rotate together with the first shaft (210). For example, when the first shaft (210) rotates, the second shaft (230) may rotate by the same amount that the first shaft (210) rotates. For example, when the first shaft (210) rotates, the second shaft (230) may rotate by the same amount that the first shaft (210) rotates around the rotational axis (RX).

[0085] In one embodiment, the second bracket (240) can accommodate a portion of the second shaft (230) (e.g., the second protrusion (232)). For example, a portion of the second shaft (230) can be positioned within the second bracket (240). For example, a portion of the second bracket (240) can surround a portion of the second shaft (230). For example, a portion of the second shaft (230) can penetrate the second bracket (240).

[0086] In one embodiment, the second bracket (240) can rotate about the second shaft (230). For example, the second bracket (240) can rotate about the rotational axis (RX) of the hinge assembly (200) about the second shaft (230). For example, the second bracket (240) can rotate about the rotational axis (RX) about the second protrusion (232).

[0087] In one embodiment, the second shaft (230) can rotate with respect to the second bracket (240). For example, the second shaft (230) can rotate with respect to the second bracket (240) about the rotational axis (RX) of the hinge assembly (200). For example, the second protrusion (232) can rotate with respect to the second bracket (240) about the rotational axis (RX).

[0088] According to one embodiment, when the second shaft (230) and the second bracket (240) rotate with respect to each other, the second protrusion (232) of the second shaft (230) and the second bracket (240) can generate frictional torque.

[0089] According to one embodiment, the third fixing member (260) may be coupled with the second shaft (230). By coupling the third fixing member (260) with the second shaft (230), the second bracket (240) may not be separated from the second shaft (230). For example, the second bracket (240) may not be separated from the second shaft (230) in the direction in which the rotation axis (RX) faces due to the third fixing member (260).

[0090] According to one embodiment, the value of the frictional torque generated between the first shaft (210) and the first bracket (220) may vary depending on the length (R1) of the outer diameter of the first protrusion (212). For example, as the length (R1) of the outer diameter of the first protrusion (212) increases, the value of the frictional torque generated between the first shaft (210) and the first bracket (220) may increase.

[0091] According to one embodiment, the value of the frictional torque generated between the second shaft (230) and the second bracket (240) may vary depending on the length (R2) of the outer diameter of the second protrusion (232). For example, as the length (R2) of the outer diameter of the second protrusion (232) increases, the value of the frictional torque generated between the second shaft (230) and the second bracket (240) may increase.

[0092] According to one embodiment, the value of the friction torque generated in the hinge assembly (200) may vary depending on the length (R1) of the outer diameter of the first protrusion (212) and the length (R2) of the outer diameter of the second protrusion (232).

[0093] According to one embodiment, the value of the friction torque generated in the hinge assembly (200) may vary depending on the number of shafts included in the hinge assembly (200). For example, the value of the friction torque generated in the hinge assembly (200) may vary depending on the number of protrusions of the shafts included in the hinge assembly (200). For example, as the number of protrusions of the shafts included in the hinge assembly (200) increases, the value of the friction torque generated in the hinge assembly (200) may increase.

[0094] According to one embodiment, the length (R1) of the outer diameter of the first protrusion (212) may be different from the length (R2) of the outer diameter of the second protrusion (232). For example, the length (R1) of the outer diameter of the first protrusion (212) may be smaller than the length (R2) of the outer diameter of the second protrusion (32). However, this is not limited thereto.

[0095] According to one embodiment, at least one of the first bracket (220) or the second bracket (240) may include metal. For example, at least one of the first bracket (220) or the second bracket (240) may include at least one of iron or stainless steel. However, the present invention is not limited thereto. For example, at least one of the first bracket (220) or the second bracket (240) may include an elastic material.

[0096] In one embodiment, at least one of the first shaft (210) or the second shaft (230) may comprise metal. For example, at least one of the first shaft (210) or the second shaft (230) may comprise a material having a higher strength than the first bracket (220) and the first bracket (240).

[0097] FIG. 6 is a drawing illustrating a first hinge assembly arranged in an electronic device according to one embodiment.

[0098] The configuration of FIG. 6 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0099] According to one embodiment, the electronic device (100) may include a first hinge assembly (200a). According to one embodiment, the first shaft (210) may be disposed in the first housing (110), and the first bracket (220) may be disposed in the second housing (120). When the first shaft (210) and the first bracket (220) rotate with respect to each other, the first housing (110) and the second housing (120) may rotate with respect to each other. For example, when the first shaft (210) rotates with respect to the first bracket (220) about a rotation axis (e.g., the rotation axis (RX) of FIG. 5), the first housing (110) may rotate with respect to the second housing (120) about the rotation axis. For example, when the first bracket (220) rotates about the rotation axis with respect to the first shaft (210), the second housing (120) can rotate about the rotation axis with respect to the first housing (110).

[0100] According to one embodiment, the first hinge assembly (200a) can generate a friction torque having a first value.

When the first shaft (210) and the first bracket (220) rotate with respect to each other, and the second shaft (230) and the second bracket (240) rotate with respect to each other, the first housing (110) and the second housing (120) may rotate with respect to each other. For example, when the first shaft (210) rotates about a rotation axis (e.g., rotation axis (RX) of FIG. 5) with respect to the first bracket (220), and the second shaft (230) rotates about a rotation axis with respect to the second bracket (240), the first housing (110) can rotate about the rotation axis with respect to the second housing (120). For example, when the first bracket (220) rotates about a rotation axis with respect to the first shaft (210), and the second bracket (240) rotates about a rotation axis with respect to the second shaft (230), the second housing (120) can rotate about the rotation axis with respect to the first housing (110).

[0104] According to one embodiment, the first hinge assembly (200a) can generate a friction torque having a first value, and the second hinge assembly (200b) can generate a friction torque having a second value. Compared to the electronic device (100) of FIG. 6, the electronic device (100) of FIG. 7 further includes the second hinge assembly (200b), thereby providing a greater friction torque than the electronic device (100) of FIG. 6.

[0105] Figure 8 is an exploded perspective view of a first hinge assembly according to one embodiment.

[0106] The configuration of FIG. 8 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0118] According to one embodiment, when the first shaft (210) and the first bracket (220) are coupled, the second portion (213) of the first shaft (210) can be visible from the outside. For example, the first body (221) of the first bracket (220) can be positioned between the first portion (211) of the first shaft (210) and the second portion (213) of the first shaft (210).

The first region of the recess (215) may be closer to the second bracket (220) than the second region of the recess (215).

[0148] In one embodiment, the first region of the recess (215) may have a first width in a direction substantially perpendicular to the direction in which the rotation axis faces. The second region of the recess (215) may have a second width in a direction substantially perpendicular to the direction in which the rotation axis faces. In one example, the length of the first width may be greater than the length of the second width. For example, the recess (215) may have an 'L' shape. However, the present invention is not limited thereto.

[0149] According to one embodiment, the second fixing member (250) may at least partially surround the second portion (213). For example, referring to FIG. 11, the second fixing member (250) may have a 'C' shape. However, the present invention is not limited thereto.

[0150] Fig. 12 is a drawing for explaining a catch according to one embodiment.

[0151] The configuration of Fig. 12 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0152] Referring to FIG. 12, the second shaft (230) according to one embodiment may include a catch (235). For example, the second shaft (230) may include a catch (235) formed in the first portion (231) of the second shaft (230). For example, the catch (235) may protrude from the inner side of the first groove (234). For example, the catch (235) may protrude from the inner side of the first groove (234) in a direction toward the inside of the first groove (234).

[0153] According to one embodiment, the catch (235) may include a first portion and a second portion that is closer to one end of the first portion (231) of the second shaft (230) than the first portion. The first portion of the catch (235) may be closer to the second protrusion than the second portion of the catch (235). According to one embodiment, the first portion of the catch (235) may have a third width in a direction substantially perpendicular to the direction in which the rotation axis faces. The second portion of the catch (235) may have a fourth width in a direction substantially perpendicular to the direction in which the rotation axis faces.

However, the present invention is not limited thereto.

[0154] FIG. 13 is a drawing for explaining a method of coupling a second hinge assembly to a first hinge assembly according to one embodiment.

[0155] The configuration of Fig. 13 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0156] Referring to FIG. 13, a first shaft (210) according to one embodiment may be coupled with a second shaft (230). For example, a catch (235) of the second shaft (230) may be inserted into a recess (215) of the first shaft (210).

[0157] According to one embodiment, when a portion of the first shaft (210) is accommodated in the second shaft (230) (e.g., accommodated in the first groove), the first shaft (210) can be coupled to the second shaft (230) by rotating the first shaft (210) about a rotation axis (e.g., rotation axis (RX) of FIG. 5) by a predetermined angle. For example, in a state where the engaging portion of the second shaft (230) is received in the recess (215) of the first shaft (210), the first shaft (210) can be coupled with the second shaft by rotating the first plate (223) of the first bracket (220) and the second plate (243) (or the third plate (244)) of the second bracket (240) about the rotation axis with respect to the second shaft (230) by an angle (e.g., a first angle). For example, when the first plate (223) and the second plate (243) (or the third plate (244)) form a first angle, a part of the first shaft (210) can be received in the second shaft (230). For example, when the first plate (223) and the second plate (243) (or the third plate (244)) form a first angle, the first The engaging portion of the second shaft (230) can be accommodated in the recess (215) of the shaft (210). In one example, the first angle may be about 30 degrees. However, the present invention is not limited thereto.

[0158] FIG. 14 is a drawing for explaining the movement of a catch within a recess according to one embodiment.

[0159] The configuration of Fig. 14 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0160] FIG. 14 is a schematic diagram illustrating a state in which a catch (235) of a second shaft (e.g., the second shaft (230) of FIG. 12) is positioned inside a recess (215) of a first shaft (210). FIG. 14 (a) is a diagram illustrating a state in which the catch (235) is inserted into the recess (215). FIG. 14 (b) is a diagram illustrating a state in which the catch (235) moves as the second shaft (230) rotates relative to the first shaft (210) while the catch (235) is inserted into the recess (215).

[0161] Referring to (a) of FIG. 14, a catch (235) according to one embodiment can be inserted into the inside of a recess (215). For example, the catch (235) can be inserted into the recess (215) in a direction (e.g., a first direction (D1)) in which a rotation axis (e.g., a rotation axis (RX) of FIG. 5) faces. For example, when a part of a first shaft (210) is accommodated in a second shaft (e.g., a second shaft (230) of FIG. 13), the catch (235) can be accommodated in the recess (215).

[0162] Referring to (b) of FIG. 14, the engaging portion (235) according to one embodiment can move along the recess (215). For example, when the second shaft rotates around the rotation axis with respect to the first shaft (210), the engaging portion (235) can move in the second direction (D2) along the recess (215). For example, the engaging portion (235) can rotate by a predetermined angle while being inserted into the recess (215). For example, the engaging portion (235) can rotate by an angle (for example, the first angle in FIG. 13) between the first plate (for example, the first plate (223) of FIG. 13) and the second plate (for example, the second plate (243) of FIG. 13) (or the third plate) while being inserted into the recess (215).

[0163] According to one embodiment, the recess (215) may be formed to limit movement of the second shaft (e.g., the second shaft (230) of FIG. 13) in the direction in which the rotation axis faces when the catch (235) moves. For example, the recess (215) may be formed to limit movement of the catch (235) in the direction in which the rotation axis faces when the catch (235) moves. For example, a portion of the catch (235) may be caught in the direction in which the rotation axis faces while being positioned inside the recess (215). For example, the portion of the catch (235) may overlap the first shaft (210) in the direction in which the rotation axis faces.

[0164] FIG. 15 is a drawing for explaining a first fixing member according to one embodiment.

[0165] The configuration of Fig. 15 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0166] Referring to (b) of FIG. 14, the second shaft (230) can rotate about the rotational axis with respect to the first shaft (210) so that the catch (235) moves along the recess (215). According to one embodiment, when the first hinge assembly (200a) and the second hinge assembly (200b) are coupled, the second shaft (230) and the second bracket (240) can rotate together with respect to the first shaft (210) and the first bracket (220). For example, when the second shaft (230) rotates with respect to the first shaft (210), the second bracket (240) can rotate with respect to the first bracket (220).

[0167] According to one embodiment, when the first hinge assembly (200a) and the second hinge assembly (200b) are coupled, the second plate (243) can rotate by a first angle (e.g., the first angle in FIG. 13) with respect to the first plate (223). For example, with a portion of the first shaft (210) accommodated within the second shaft (230), the second plate (243) can rotate by a first angle (e.g., the first angle in FIG. 13) with respect to the first plate (223).

[0168] According to one embodiment, the second plate (243) may be arranged substantially parallel to the first plate (223) as the second plate (243) rotates by a first angle (e.g., the first angle of FIG. 13) with respect to the first plate (223). For example, one side of the first plate (223) may form a substantially coplanar surface with one side of the second plate (243).

[0169] According to one embodiment, the third plate (244) may correspond at least partially to the first plate (223). For example, the third plate (244) may at least partially face the first plate (223). For example, the third plate (244) may at least partially contact the first plate (223). For example, the third plate (244) may at least partially overlap the first plate (223).

[0170] According to one embodiment, the first fixing member (270) can fix the second shaft (230) to the first shaft (210) when the first shaft (210) is coupled with the second shaft (230). For example, the first fixing member (270) can penetrate the second shaft (230) and be at least partially inserted into the first shaft (210) when the first plate (223) and the second plate (243) are arranged substantially parallel. For example, the first fixing member (270) can be inserted into a second groove formed in the first shaft (210) and the second shaft (230). Specific details regarding the first fixing member (270) will be described later with reference to FIG. 16.

[0171] FIG. 16 is a cross-sectional view of a hinge assembly according to one embodiment taken along line A-A' of FIG. 15.

[0172] The configuration of Fig. 16 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0173] According to one embodiment, the first fixing member (270) may be positioned in the second groove. For example, the first fixing member (270) may be positioned inside the second groove. For example, the first fixing member (270) may be inserted into the second groove. For example, the first fixing member (270) may be fitted into the second groove.

[0174] According to one embodiment, the second groove may be formed by the first shaft (210) and the second shaft (230). For example, the second groove may be formed by the second shaft (230) rotating about a rotational axis with respect to the first shaft (210) and being coupled with the first shaft (210). For example, the second groove may be formed by the engaging portion (235) moving along the recess (215). For example, referring to FIG. 16, the second groove may be formed by a third groove (216) formed in the first shaft (210) and a third hole (236) penetrating the second shaft (230). For example, the second groove may be formed by the third groove (216) and the third hole (236) being connected to each other. For example, the third groove (216) and the third hole (236) can be connected when the second shaft (230) rotates around the rotation axis with respect to the first shaft (210) and is coupled with the first shaft (210). The second groove can be formed by overlapping the third groove (216) and the third hole (236). For example, the third groove (216) and the third hole (236) can be overlapped when the second shaft (230) rotates around the rotation axis with respect to the first shaft (210) and is coupled with the first shaft (210).

[0175] According to one embodiment, the first fixing member (270) is disposed in the second groove, so that the first shaft (210) and the second shaft (230) can rotate together. The first fixing member (270) is disposed in the second groove, so that the second shaft (230) can be fixed to the first shaft (210). For example, the first fixing member (270) is disposed in the second groove, so that the second shaft (230) may not rotate with respect to the first shaft (210).

[0176] According to one embodiment, the first fixing member (270) may include a pin that is inserted into the second groove or separated from the second groove in a direction substantially perpendicular to the rotation axis (e.g., the rotation axis (RX) of FIG. 5). However, the present invention is not limited thereto. For example, the first fixing member (270) may include a sliding member that is inserted into the second groove and moves within the second groove in a direction substantially parallel to the rotation axis. For example, the first fixing member (270) may include a button. When the first fixing member (270) includes at least one of a button and a sliding member, a user can easily couple or separate the first shaft (210) and the second shaft (230).

[0177] According to one embodiment, the method of coupling the first shaft (210) and the second shaft (230) is not limited to the above-described content. For example, the first shaft (210) and the second shaft (230) may be coupled through welding or an adhesive member. For example, the first shaft (210) and the second shaft (230) may be coupled through a fitting structure. For example, one end of the first shaft (210) may have a male thread shape, and one end of the second shaft (230) may have a female thread shape that is coupled with the male thread shape of the first shaft (210). For example, one end of the first shaft (210) may have a female thread shape, and one end of the second shaft (230) may have a male thread shape that is coupled with the female thread shape of the first shaft (210).

[0209] The configuration of Fig. 22 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0210] Referring to FIG. 22, the length (R1) of the outer diameter of the first shaft (210) according to one embodiment may be different from the length (R2) of the outer diameter of the second shaft (230). For example, the length (R1) of the outer diameter of the first protrusion (e.g., the first protrusion (212) of FIG. 5) of the first shaft (210) may be different from the length (R2) of the outer diameter of the second protrusion (e.g., the second protrusion (232) of FIG. 5) of the second shaft (230). For example, the length (R1) of the outer diameter of the first protrusion of the first shaft (210) may be smaller than the length (R2) of the outer diameter of the second protrusion of the second shaft (230).

[0211] According to one embodiment, the first shaft (210) can have a first length (L1) in a direction (e.g., in the y-axis direction) in which the rotation axis (e.g., the rotation axis (RX) of FIG. 5) faces. For example, a first protrusion of the first shaft (210) can have a first length (L1) in a direction in which the rotation axis faces. The second shaft (230) can have a second length (L2) in a direction in which the rotation axis faces. For example, a second protrusion of the second shaft (230) can have a second length (L2) in a direction in which the rotation axis faces.

[0212] In one embodiment, the first length (L1) may be different from the second length (L2). For example, the first length (L1) may be less than the second length (L2). However, this is not limited thereto. For example, the first length (L1) may be less than or equal to the second length (L2). The first length (L1) may also be greater than the second length (L2).

[0213] According to one embodiment, the electronic device (100) may include a component (280) positioned adjacent to the hinge assembly. In one example, the component (280) may include at least one of a printed circuit board or a battery, but is not limited thereto. For example, the component (280) may include various components mounted within the electronic device (100).

[0214] According to one embodiment, the length (R1) of the outer diameter of the first shaft (210) and the length (R2) of the outer diameter of the second shaft (230) may vary depending on the size and / or shape of the space in which the hinge assembly is mounted. For example, the component (280) may include a first region (280a) having a third length (R3) and a second region (280b) having a fourth length (R4) in a direction substantially perpendicular to the direction in which the rotation axis faces (e.g., the y-axis direction) and a second region (280b) having a fourth length (R4). When the third length (R3) is greater than the fourth length (R4), the size of the region corresponding to the first region (280a) among the regions in which the hinge assembly is mounted may be smaller than the size of the region corresponding to the second region (280b) among the regions in which the hinge assembly is mounted. For example, the length in the x-axis direction of the region corresponding to the first region (280a) among the regions where the hinge assembly is mounted may be smaller than the length in the x-axis direction of the region corresponding to the second region (280b) among the regions where the hinge assembly is mounted. In this case, the length (R1) of the outer diameter of the first shaft (210) may be smaller than the length (R2) of the outer diameter of the second shaft (230). For example, the length (R1) of the outer diameter of the first protrusion of the first shaft (210) may be smaller than the length (R2) of the outer diameter of the second protrusion of the second shaft (230).

[0215] According to one embodiment, the longer the length of the projection of the shaft, the greater the value of the frictional torque generated on the shaft. According to one embodiment, the longer the length of the outer diameter of the projection of the shaft, the greater the value of the frictional torque generated on the shaft.

[0216] FIG. 23 is a drawing for explaining a first shaft and a second shaft according to one embodiment.

[0217] The configuration of Fig. 23 may be referenced by the configuration of other drawings. For configurations that are identical or substantially identical to those of other drawings, the same terms and / or the same reference numerals are used, and redundant descriptions are omitted.

[0218] Referring to FIG. 23, the length (R5) of the outer diameter of the first shaft (510) according to one embodiment may be different from the length (R6) of the outer diameter of the second shaft (530). For example, the length (R5) of the outer diameter of the first protrusion (e.g., the first protrusion (212) of FIG. 5) of the first shaft (510) may be different from the length (R6) of the outer diameter of the second protrusion (e.g., the second protrusion (232) of FIG. 5) of the second shaft (530). For example, the length (R5) of the outer diameter of the first protrusion of the first shaft (510) may be greater than the length (R6) of the outer diameter of the second protrusion of the second shaft (530).

[0219] According to one embodiment, the first shaft (510) can have a first length (L3) in a direction (e.g., in the y-axis direction) in which the rotation axis (e.g., the rotation axis (RX) of FIG. 5) faces. For example, a first protrusion of the first shaft (510) can have a first length (L3) in the direction in which the rotation axis faces. The second shaft (530) can have a second length (L4) in the direction in which the rotation axis faces. For example, a second protrusion of the second shaft (530) can have a second length (L4) in the direction in which the rotation axis faces.

[0220] In one embodiment, the first length (L3) may be different from the second length (L4). For example, the first length (L3) may be greater than the second length (L4). However, this is not limited thereto. For example, the first length (L3) may be greater than or equal to the second length (L4). The first length (L3) may also be less than the second length (L4).

[0221] According to one embodiment, the electronic device (500) may include a component (580) positioned adjacent to the hinge assembly. In one example, the component (580) may include at least one of a printed circuit board or a battery, but is not limited thereto. For example, the component (580) may include various components mounted within the electronic device (500).

[0222] According to one embodiment, the length (R5) of the outer diameter of the first shaft (510) and the length (R6) of the outer diameter of the second shaft (530) may vary depending on the size and / or shape of the space in which the hinge assembly is mounted. For example, the component (580) may include a first region (580a) having a fifth length (R7) and a second region (580b) having a sixth length (R8) in a direction substantially perpendicular to the direction in which the rotational axis faces (e.g., the y-axis direction) and a second region (580b) having a sixth length (R8). When the fifth length (R7) is smaller than the sixth length (R8), the size of the region corresponding to the first region (580a) among the regions in which the hinge assembly is mounted may be larger than the size of the region corresponding to the second region (580b) among the regions in which the hinge assembly is mounted. For example, the length in the x-axis direction of the region corresponding to the first region (580a) among the regions where the hinge assembly is mounted may be greater than the length in the x-axis direction of the region corresponding to the second region (580b) among the regions where the hinge assembly is mounted. In this case, the length (R5) of the outer diameter of the first shaft (510) may be greater than the length (R6) of the outer diameter of the second shaft (530). For example, the length (R5) of the outer diameter of the first protrusion of the first shaft (510) may be less than the length (R6) of the outer diameter of the second protrusion of the second shaft (530).
