[0055] According to one embodiment, the housing (100) may include a first housing (110), a second housing (120), and a third housing (130). The first housing (110), the second housing (120), and the third housing (130) may form at least a portion of the back surface and at least a portion of the side surface of the electronic device (10). In one embodiment, at least one of the first housing (110), the second housing (120), or the third housing (130) may include a conductive material (e.g., a metal).

[0056] According to one embodiment, the electronic device (10) may have an unfolded state, a folded state, and / or an intermediate state.

[0057] In one embodiment, the unfolded state may include a state in which at least a portion of the housing (100) is unfolded. The unfolded state may include a first unfolded state in which the first housing (110) and the second housing (120) are arranged at a 180-degree angle, and the second housing (120) and the third housing (130) are arranged at a 180-degree angle.

[0058] In one embodiment, the unfolded state may include a second unfolded state in which the first housing (110) and the second housing (120) are arranged at a 180 degree angle to each other, and the second housing (120) and the third housing (130) are arranged at a predetermined angle to each other.

[0059] In one embodiment, the unfolded state may include a third unfolded state in which the first housing (110) and the second housing (120) are arranged at a predetermined angle to each other, and the second housing (120) and the third housing (130) are arranged at a 180 degree angle to each other.

[0060] In one embodiment, the unfolded state may include a fourth unfolded state in which the first housing (110) and the second housing (120) are arranged at a 180 degree angle to each other, and the second housing (120) and the third housing (130) are arranged facing each other.

[0061] In one embodiment, the unfolded state may include a fifth unfolded state in which the first housing (110) and the second housing (120) are positioned facing each other, and the second housing (120) and the third housing (130) are positioned at a 180 degree angle to each other.

[0062] In one embodiment, the folded state may include a state in which the housing (100) is folded. In one embodiment, the folded state may include a first folded state in which the second housing (120) and the first housing (110) are arranged to face each other, and the second housing (120) and the third housing (130) are arranged to form a predetermined angle with each other.

[0063] In one embodiment, the folded state may include a second folded state in which the second housing (120) and the first housing (110) are arranged facing each other, and the second housing (120) and the third housing (130) are arranged facing each other. In the second folded state, the third housing (130) and the first housing (110) may be arranged facing each other.

[0064] In one embodiment, the folded state may include a third folded state in which the third housing (130) and the second housing (120) are positioned facing each other, and the second housing (120) and the first housing (110) are positioned at a predetermined angle to each other.

[0065] 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, and the second housing (120) and the third housing (130) are arranged at a certain angle. However, the specific angle formed by the first housing (110) and the second housing (120) when in the folded state and the unfolded state, and / or the specific angle formed by the second housing (120) and the third housing (130) are for convenience of explanation, and may have an angle less than 180 degrees (°) or greater than 0 degrees (°), but are not limited thereto.

[0066] According to one embodiment, at least a portion of the housing (100) may be formed of at least one of a metallic material (e.g., titanium and / or aluminum) or a non-metallic material having a rigidity of a selected size to support the flexible display (200).

[0067] According to one embodiment, the flexible display (200) may be placed in the housing (100). For example, the flexible display (200) may be mounted on a recess formed by the housing (100) and may form most of the front surface of the electronic device (10). In one embodiment, the flexible display (200) may include a first region (210), a second region (220), and a third region (230). The first region (210) and the second region (220) of the flexible display (200) may be divided around a first axis, which is a reference for folding or unfolding the electronic device (10). The second region (220) and the third region (230) of the flexible display (200) may be divided around a second axis, which is a reference for folding or unfolding the electronic device (10). The first axis and the second axis may be parallel to each other.

[0068] According to one embodiment, the region division of the flexible display (200) illustrated in FIG. 1 is exemplary, and in one embodiment, the flexible display (200) may be divided into four or more regions depending on the structure or function. For example, the flexible display (200) may be divided into a first folding region having a predetermined curvature when the electronic device (10) is folded around a first folding axis (e.g., the first axis), a first region (210) adjacent to the first housing (110) based on the folding region, a second region (220) adjacent to the second housing (120), a second folding region having a predetermined curvature when the electronic device (10) is folded around a second folding axis (e.g., the second axis), and a third region (230) adjacent to the third housing (130). In one example, the first region (210) and the second region (220) may have shapes that are overall symmetrical about the first folding axis (e.g., the first axis). In one example, the second region (220) and the third region (230) may have shapes that are overall symmetrical about the second folding axis (e.g., the second axis).

[0069] According to one embodiment, the arrangement structure of the first region (210), the second region (220), and the third region (230) of the flexible display (200) may vary depending on the state of the electronic device (10). For example, when the electronic device (10) is in an unfolded state, the first region (210) and the second region (220) of the flexible display (200) may form a 180-degree angle with respect to each other. For example, when the electronic device (10) is in an unfolded state, the second region (220) and the third region (230) of the flexible display (200) may form a 180-degree angle with respect to each other.

[0070] According to one embodiment, when the electronic device (10) is in an unfolded state, the first region (210) and the second region (220) of the flexible display (200) may face in the same direction (e.g., the +z direction). For example, when the electronic device (10) is in an unfolded state, the second region (220) and the third region (230) of the flexible display (200) may face in the same direction (e.g., the +z direction). For example, when the electronic device (10) is in an unfolded state, the first region (210), the second region (220), and the third region (230) of the flexible display (200) may face in the same direction (e.g., the +z direction).

[0071] According to one embodiment, when the electronic device (10) is in a folded state, the first region (210) and the second region (220) of the flexible display (200) may form a narrow angle (e.g., between 0 and 10 degrees) with respect to each other and may face each other. In one embodiment, when the electronic device (10) is in a folded state, the second region (220) and the third region (230) of the flexible display (200) may form a narrow angle (e.g., between 0 and 10 degrees) with respect to each other and may face each other. For example, when the electronic device (10) is in a folded state, the first region (210) and the third region (230) of the flexible display (200) may face the same direction (e.g., the -z direction).

[0072] According to one embodiment, when the electronic device (10) is in an intermediate state, the first region (210) and the second region (220) of the flexible display (200) may form an angle that is greater than the folded state and less than the unfolded state, and the second region (220) and the third region (230) of the flexible display (200) may form an angle that is greater than the folded state and less than the unfolded state. For example, the flexible display (200) may be formed of a curved surface having at least a predetermined curvature, and the curvature at this time may be less than when the flexible display (200) is folded.

[0073] However, the specific angles formed by the first region (210), the second region (220), and the third region (230) in the folded and unfolded states described above are for convenience of explanation and are not limited thereto.

[0140] According to one embodiment, at least one of the plurality of protrusions (410) may be formed parallel to the rotational axis (e.g., y-axis direction) of the second hinge assembly (the second hinge assembly (170) of FIG. 3). According to one embodiment, at least one of the plurality of protrusions (410) may protrude in a direction perpendicular to one surface of the second hinge housing (the second hinge housing (190) of FIG. 10).

[0141] FIG. 12 is a perspective view of a second housing and a third housing including a protrusion according to one embodiment. FIG. 13 is a drawing of the second hinge housing of one embodiment of FIG. 12 at least partially disposed between the second housing and the third housing.

[0142] The configurations of FIGS. 12 and 13 may be referenced by the configurations 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, and any duplicate descriptions are omitted.

[0143] Fig. 12 is a drawing of the second housing (120) and the third housing (130) cut along line A-A' of Fig. 11.

[0144] Referring to FIG. 12, the plurality of protrusions (410) according to one embodiment may include a first protrusion (411), a second protrusion (412), and a third protrusion (413). However, the present invention is not limited thereto. For example, the plurality of protrusions (410) may omit one of the above-described protrusions, or may further include at least one protrusion. For example, the plurality of protrusions (410) may further include a fourth protrusion (414).

[0145] According to one embodiment, the first protrusion (411), the second protrusion (412), and the third protrusion (413) may be sequentially arranged in a direction from the first end (131) of the third housing (130) toward the second end (e.g., the second end (132) of FIG. 8) of the third housing. For example, the first protrusion (411) may be arranged adjacent to the first end (131) of the third housing (130). The second protrusion (412) may be arranged between the first protrusion (411) and the third protrusion (413). The third protrusion (413) may be arranged closer to the second end of the third housing (130) than the first protrusion (411) and the second protrusion (412). However, the present invention is not limited thereto. For example, the first protrusion (411), the second protrusion (412), the third protrusion (413), and the fourth protrusion (414) can be sequentially arranged in a direction from the first end (131) of the third housing (130) toward the second end of the third housing.

[0146] According to one embodiment, the first protrusion (411) may have a first height in a direction (e.g., +z direction) from the inner side (130a) of the third housing (130) toward the second hinge housing (e.g., the second hinge housing (190) of FIG. 10). The second protrusion (412) may have a second height in a direction from the inner side (130a) of the third housing (130) toward the second hinge housing. The third protrusion (413) may have a third height in a direction from the inner side (130a) of the third housing (130) toward the second hinge housing. In one example, the first height may be greater than or equal to the second height and the third height.

[0147] In one example, the heights of the plurality of protrusions (410) may gradually increase or decrease in the direction from the first end (131) of the third housing (130) toward the second end (e.g., the second end (132) of FIG. 8) of the third housing. For example, the first height of the first protrusion (411) may be greater than or equal to the second height of the second protrusion (412). For example, the second height of the second protrusion (412) may be greater than or equal to the third height of the third protrusion (413).

[0148] According to one embodiment, the fourth protrusion (414) may have a fourth height in a direction (e.g., +z direction) from the inner side (130a) of the third housing (130) toward the second hinge housing (e.g., the second hinge housing (190) of FIG. 10). In one example, the fourth height of the fourth protrusion (414) may be greater than at least one of the second height of the second protrusion (412) or the third height of the third protrusion (413). However, the present invention is not limited thereto. For example, the fourth height of the fourth protrusion (414) may be less than the first height, the second height, and the third height.

[0149] According to one embodiment, the spacing between the plurality of protrusions (410) may be the same. In one example, when the spacing between the plurality of protrusions (410) is the same, the heights of the plurality of protrusions (410) in the direction (e.g., +z direction) from the inner side (130a) of the third housing (130) toward the second hinge housing (e.g., the second hinge housing (190) of FIG. 10) may be the same. However, the present invention is not limited thereto. For example, the spacing between the plurality of protrusions (410) may gradually decrease in the direction from the first end (131) of the third housing (130) toward the second end (e.g., the second end (132) of FIG. 8) of the third housing. For example, the first gap (g1) between the first protrusion (411) and the second protrusion (412) may be greater than or equal to the second gap (g2) between the second protrusion (412) and the third protrusion (413). For example, the second gap (g2) between the second protrusion (412) and the third protrusion (413) may be greater than or equal to the third gap (g3) between the third protrusion (413) and the fourth protrusion (414). When the gap between the plurality of protrusions (410) gradually decreases in the direction from the first end (131) of the third housing (130) toward the second end (e.g., the second end (132) of FIG. 8) of the third housing (130), foreign substances introduced between the plurality of protrusions (410) may be prevented or reduced from moving into the interior of the electronic device.

[0150] According to one embodiment, the content regarding the plurality of protrusions (410) arranged in the second housing (120) may be referenced by the content regarding the plurality of protrusions (410) arranged in the third housing (130) described above. For example, the height of the plurality of protrusions (410) arranged in the second housing (120) may gradually increase in the direction from the second end (122) of the second housing (120) toward the first end (e.g., the first end (121) of FIG. 8) of the second housing. For example, the interval between the plurality of protrusions (410) arranged in the second housing (120) may gradually decrease in the direction from the second end (122) of the second housing (120) toward the first end (e.g., the first end (121) of FIG. 8) of the second housing (120). In one example, the plurality of protrusions (410) arranged in the second housing (120) may have a shape and / or position that is symmetrical with respect to the plurality of protrusions (410) arranged in the third housing (130) with respect to the space (S) between the second housing (120) and the third housing (130) (or with respect to the rotational axis (e.g., y-axis direction) of the second hinge assembly). However, the present invention is not limited thereto.

[0151] Referring to FIGS. 9 and 13, when an electronic device according to an embodiment includes a plurality of protrusions (410), the width of the housing (e.g., the third housing (130)) may be smaller than the width (w5) of the housing (e.g., the third housing (130)) when the electronic device includes a sweeper (e.g., the sweeper (310) of FIG. 9). For example, referring to FIG. 9, when an electronic device according to an embodiment includes a sweeper, the thickness of the bezel of the housing may be thick to secure a space for placing the sweeper. Accordingly, when an electronic device includes a plurality of protrusions (410), the electronic device may provide a wider display (e.g., the sub-display (240) of FIG. 2), and the aesthetics of the electronic device may be improved.

[0152] According to one embodiment, at least two of the plurality of protrusions (410) may have different materials. For example, at least two of the first protrusion (411), the second protrusion (412), the third protrusion (413), and the fourth protrusion (414) may have different materials.

[0164] FIG. 15 is a cross-sectional view illustrating a portion of an electronic device including a second hinge housing and a sealing member according to one embodiment. FIG. 16 is a perspective view illustrating a portion of an electronic device including a second hinge housing and a sealing member.

[0165] The configurations of FIGS. 15 and 16 may be referenced by the configurations 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] According to one embodiment, at least one of the plurality of second anti-vibration members may include at least one of a protrusion, a sweeper, a brush, or a sealing member (910). For example, at least one of the plurality of protrusions (e.g., the plurality of protrusions (410) of FIG. 10) may include at least one of a sweeper, a brush, or a sealing member (910). Hereinafter, in FIGS. 15 and 16 , the content that at least one of the plurality of protrusions includes a sealing member (910) will be described, and in FIGS. 17 and 18 , the content that at least one of the plurality of protrusions includes a brush (1010) will be described.

[0167] Referring to FIG. 15, at least one of the plurality of protrusions according to one embodiment may include a sealing member (910). That is, the electronic device may include a plurality of protrusions, and at least one of the protrusions may be formed as a sealing member (910). The sealing member (910) may be disposed in at least one of the second housing (320) or the third housing (330). However, the present invention is not limited thereto. For example, the sealing member (910) may also be disposed in the second hinge housing (390).

[0168] According to one embodiment, the sealing member (910) can be coupled with at least one of the second housing (320) or the third housing (330). For example, the sealing member (910) can be adhered to at least one of the second housing (320) or the third housing (330). For example, the sealing member (910) can be adhered to at least one of the second housing (320) or the third housing (330) using an adhesive member. In one example, the adhesive member can include at least one of an adhesive tape, a bond, or silicone.

The remaining portion of the sealing member (910) may be disposed outside at least one of the first recess (321) or the second recess (331). For example, the sealing member (910) may protrude from at least one of the first recess (321) or the second recess (331). The first recess (321) or the second recess (331) may be a recess (for example, a recess having a width (g1, g2, or g3) as shown in FIG. 12) formed between two of the plurality of protrusions of the second housing (320) or the third housing (330). However, the present invention is not limited thereto, and for example, the first recess (321) and the second recess (331) may be recesses formed between two of the plurality of protrusions of the second housing (320) or the third housing (330).

[0174] According to one embodiment, the sealing member (910) may include a first portion (911) facing at least one of the second housing (320) or the third housing (330) and a second portion (912) disposed closer to the second hinge housing (390) than the first portion (911). In one example, the first portion (911) of the sealing member (910) may be disposed within at least one of the first recess (321) or the second recess (331). In one example, the second portion (912) of the sealing member (910) may be in contact with the second hinge housing (390). For example, the second portion (912) of the sealing member (910) may be in contact with the outside of the second hinge housing (390). According to one embodiment, the width of the first portion (911) may be greater than or equal to the width of the second portion (912), but is not limited thereto.

[0175] FIG. 17 is a cross-sectional view illustrating a portion of an electronic device including a second hinge housing and a brush. FIG. 18 is a perspective view illustrating a portion of an electronic device including a second hinge housing and a brush.

[0176] The configurations of FIGS. 17 and 18 may be referenced by the configurations 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, and any duplicate descriptions are omitted.

[0177] Referring to FIGS. 17 and 18, at least one of the plurality of protrusions according to one embodiment may include a brush (1010). The brush (1010) may be disposed in at least one of the second housing (420) or the third housing (430), but is not limited thereto. For example, the brush (1010) may also be disposed in the second hinge housing (490). Additionally, the brush (1010) may be disposed in a recess formed between two of the plurality of protrusions of the second housing (420) or the third housing (430) (for example, a recess having a width (g1, g2, or g3) as illustrated in FIG. 12). However, this should not be considered limiting. For example, the brush (1010) may be positioned within a recess formed between two of a plurality of protrusions (e.g., protrusions having a width (g1, g2, or g3) as illustrated in FIG. 12) of the second housing (420) and the third housing (430).

[0178] In one embodiment, the brush (1010) can be coupled with at least one of the second housing (420) or the third housing (430). In one example, the brush (1010) can be coupled with at least one of the second housing (420) or the third housing (430) to rotate with respect to at least one of the second housing (420) or the third housing (430). In one example, the brush (1010) can comprise an interdental brush or an eyelash.

[0179] According to one embodiment, the brush (1010) may be arranged to rotate between at least one of the second hinge housing (490) and the second housing (420), or between the second hinge housing (490) and the third housing (430).

[0180] In one embodiment, the brush (1010) may protrude in a direction toward the second hinge housing (490). For example, the brush (1010) may protrude in a direction toward the outside of the second hinge housing (490) from at least one of the inside of the second housing (420) or the inside of the third housing (430). In one example, the brush (1010) may protrude in a direction toward the second hinge assembly (470).

[0181] According to one embodiment, the brush (1010) may face the second hinge housing (490). In one example, the brush (1010) may be in contact with the second hinge housing (490). For example, the brush (1010) may be arranged to rotate relative to the second hinge housing (490) while in contact with the second hinge housing (490). By rotating the brush (1010) while in contact with the second hinge housing (490), the brush (1010) may prevent or reduce foreign substances from entering the electronic device from the outside of the electronic device.

[0182] According to one embodiment, the brush (1010) is made of a soft material and can move smoothly with respect to the second hinge housing (490) when the state of the electronic device changes. Accordingly, the brush (1010) can prevent or reduce driving failure due to overlap between the brush (1010) and the second hinge housing (490).

[0183] FIG. 19 is a drawing for explaining the relationship between a plurality of protrusions and a second hinge housing in an unfolded state of an electronic device according to one embodiment.

[0184] The configuration of Fig. 19 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.

[0185] Referring to FIG. 19, the plurality of protrusions may include a first protrusion (1111), a second protrusion (1112), and a third protrusion (1113). However, the present invention is not limited thereto. For example, the plurality of protrusions may omit at least one of the above-described protrusions, or may further include at least one other protrusion. For example, the plurality of protrusions may further include a fourth protrusion (1114).

[0186] According to one embodiment, the electronic device may include a plurality of grooves (e.g., first grooves (1211)) formed between a plurality of protrusions. The plurality of grooves may be formed by the plurality of protrusions. The plurality of grooves may be formed in at least one of the second housing or the third housing (530). Although only the third housing (530) is illustrated in FIG. 19, the description of the second housing may be referenced by the description of the third housing (530).

[0187] According to one embodiment, the electronic device may include, but is not limited to, a first groove (1211) formed between the first protrusion (1111) and the second protrusion (1112), and a second groove (1212) formed between the second protrusion (1112) and the third protrusion (1113). For example, the electronic device may omit at least one of the grooves described above, or may further include at least one groove. For example, the electronic device may further include a third groove (1213) formed between the third protrusion (1113) and the fourth protrusion (1114).

[0188] According to one embodiment, the first groove (1211) may have a first depth (d1) in a direction opposite to the direction in which the plurality of protrusions protrude (e.g., the +z direction) (e.g., the -z direction). The second groove (1212) may have a second depth (d2) in a direction opposite to the direction in which the plurality of protrusions protrude. In one example, the first depth (d1) may be greater than or equal to the second depth (d2), but is not limited thereto.

[0189] According to one embodiment, the depth of the plurality of grooves may gradually decrease in a direction from the first end (531) of the third housing (530) toward the second end (e.g., the second end (132) of FIG. 8) of the third housing (530). For example, the first depth (d1) of the first groove (1211) may be greater than or equal to the second depth (d2) of the second groove (1212). For example, the second depth (d2) of the second groove (1212) may be greater than or equal to the third depth (d3) of the third groove (1213). However, the present invention is not limited thereto. In one example, the third depth (d3) of the third groove (1213) may be greater than the first depth (d1) of the first groove (1211) and the second depth (d2) of the second groove (1212).

[0190] According to one embodiment, the depth of the plurality of grooves (e.g., the first groove (1211)) may vary depending on the thickness of the housing (e.g., the third housing (530)) in which the plurality of grooves are formed. For example, the depth of the groove may increase as the thickness of the housing in the portion where the grooves are formed increases. For example, the depth of the groove formed in the first portion of the third housing (530) may be greater than the depth of the groove formed in the second portion of the third housing (530) which is thinner than the first portion.

[0191] According to one embodiment, the first protrusion (1111) may be disposed at the first end (531) of the third housing (530). For example, the edge (531) of the third housing (530) may include the first protrusion (1111). For example, the edge (531) of the third housing (530) may include a side of the first protrusion (1111).

[0192] According to one embodiment, depending on the state of the electronic device (10), the protrusion among the plurality of protrusions having the smallest distance from the second hinge housing (590) may vary. For example, in an unfolded state (e.g., the unfolded state of FIG. 1) of the electronic device (e.g., the electronic device (10) of FIG. 1), the first protrusion (1111) among the plurality of protrusions may have the smallest distance from the second hinge housing (590). For example, the first protrusion (1111) among the plurality of protrusions may have the smallest distance from the second hinge housing (590) and the third housing (530) in the direction toward the second hinge housing (590) (e.g., the +z direction).

[0193] In the following drawings 20, 21, 22 and 23, as the state of the electronic device changes, the change in the protrusion having the smallest distance from the second hinge housing (590) among the plurality of protrusions will be described.

[0194] FIGS. 20, 21, 22, and 23 are drawings for explaining the relationship between a plurality of protrusions and a second hinge housing according to a state of an electronic device according to one embodiment.

[0195] According to one embodiment, depending on the first angle at which the third housing (530) is inclined with respect to the second hinge housing (590), the protrusion among the plurality of protrusions having the smallest distance from the second hinge housing (590) may vary. For example, depending on the first angle of the hinge structure of the second hinge assembly (e.g., the second hinge assembly (170) of FIG. 3), the protrusion among the plurality of protrusions having the smallest distance from the second hinge housing (590) may vary. For example, depending on the first angle at which the third housing (530) is inclined with respect to the unfolded state of the electronic device, the protrusion among the plurality of protrusions having the smallest distance from the second hinge housing (590) may vary. For example, depending on the first angle at which the third housing (530) is inclined with respect to the outer side (591) of the second hinge housing (590), the protrusion among the plurality of protrusions having the smallest distance from the second hinge housing (590) may vary. According to one embodiment, the positions of the plurality of protrusions may be determined in consideration of the first angle.

[0196] According to one embodiment, when the first angle is greater than or equal to about 0 degrees and less than about 6 degrees, the fourth protrusion (1114) among the plurality of protrusions may have a minimum distance from the second hinge housing (590). In one example, the fourth protrusion (1114) may be positioned at a position where the distance from the second hinge housing (590) is minimized when the first angle is greater than or equal to about 0 degrees and less than about 6 degrees.

[0197] Referring to FIG. 20, according to one embodiment, when the first angle is about 6 degrees, the third protrusion (1113) and the fourth protrusion (1114) among the plurality of protrusions may have a minimum distance from the second hinge housing (590). In one example, the third protrusion (1113) and the fourth protrusion (1114) may be positioned at a position where the distance from the second hinge housing (590) is minimized when the first angle is about 6 degrees.

[0198] According to one embodiment, when the first angle is greater than about 6 degrees and less than about 40 degrees, the third protrusion (1113) among the plurality of protrusions may have a minimum distance from the second hinge housing (590). In one example, the third protrusion (1113) may be positioned at a position where the distance from the second hinge housing (590) is minimized when the first angle is greater than about 6 degrees and less than about 40 degrees.

[0199] Referring to FIG. 21, according to one embodiment, when the first angle is about 40 degrees, the second protrusion (1112) and the third protrusion (1113) among the plurality of protrusions may have a minimum distance from the second hinge housing (590). In one example, the second protrusion (1112) and the third protrusion (1113) may be positioned at a position where the distance from the second hinge housing (590) is minimized when the first angle is about 40 degrees.

[0200] Referring to FIG. 22, according to one embodiment, when the first angle is greater than about 40 degrees and less than about 79 degrees, the second protrusion (1112) among the plurality of protrusions may have a minimum distance from the second hinge housing (590). In one example, the second protrusion (1112) may be positioned at a position where the distance from the second hinge housing (590) is minimized when the first angle is greater than about 40 degrees and less than about 79 degrees.

[0201] Referring to FIG. 23, according to one embodiment, when the first angle is greater than about 79 degrees and less than about 90 degrees, the first protrusion (1111) among the plurality of protrusions may have a minimum distance from the second hinge housing (590). In one example, the first protrusion (1111) may be positioned at a position where the distance from the second hinge housing (590) is minimized when the first angle is greater than about 79 degrees and less than about 90 degrees.

[0202] FIG. 24 is a drawing for explaining the positions of a plurality of protrusions according to a state of an electronic device according to one embodiment.

[0203] The configuration of Fig. 24 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.

[0204] According to one embodiment, the plurality of protrusions may be disposed in at least one of the third housing (530) or the second housing (e.g., the second housing (120) of FIG. 1). Referring to FIGS. 19 and 24, the first protrusion (1111) according to one embodiment may be disposed in the first position (a1). In one example, the first position (a1) may include the first end (531) of the third housing (530). In one example, the first position (a1) may be adjacent to the first end (531) of the third housing (530). In an unfolded state of the electronic device (10) (for example, when the angle between the third housing (530) or the second housing is 0 degrees), the first protrusion (1111) of the first position (a1) may be a first protrusion for blocking dust or foreign substances entering from the outside. In addition, in a folded state of the electronic device (10) (for example, when the angle between the third housing (530) or the second housing is 79 degrees to 90 degrees), the first protrusion (1111) of the first position (a1) may be at a position having the smallest gap toward the hinge housing (590).

[0205] According to one embodiment, the third protrusion (1113) may be disposed at a third position (a3). In one example, the third position (a3) ​​may be adjacent to a position where a rear cover (e.g., the rear cover (150) of FIG. 2) disposed in the third housing (530) is disposed. In one example, the third position (a3) ​​may be adjacent to a position where a sub-display (e.g., the sub-display (240) of FIG. 2) disposed in the second housing is disposed. For example, the third position (a3) ​​may be located between the rear cover disposed in the third housing (530) and the first position (a1). For example, the third position (a3) ​​may be located between the sub-display disposed in the second housing and the first position (a1). In one example, the thickness (e.g., thickness in the z-axis direction) of the housing (530) at the third position (a3) ​​may be thicker than the thickness of the housing (530) at the fourth position (a4). However, since the third position (a3) ​​is the position where the front cutout for attaching the rear cover begins, the third protrusion (1113) may provide additional thickness to the front cutout.

[0206] According to one embodiment, at least one protrusion may be disposed between a first position (a1) and a third position (a3). For example, at least one protrusion may be disposed at a second position (a2). For example, the second protrusion (1112) may be disposed at the second position (a2). However, the present invention is not limited thereto. In one example, when the distance between the first position (a1) and the third position (a3) ​​is less than a specified first distance, no protrusion may be disposed between the first position (a1) and the third position (a3). In one example, when the distance between the first position (a1) and the third position (a3) ​​is greater than a specified second distance, a plurality of protrusions may be disposed between the first position (a1) and the third position (a3).

[0207] In one embodiment, at least one protrusion may be positioned at a fourth position (a4). For example, the fourth protrusion (1114) may be positioned at the fourth position (a4). In one example, the fourth position (a4) may include a position between the second end opposite the first end (531) of the third housing (530) and the third position (a3). The at least one protrusion positioned at the fourth position (a4) may prevent or hinder foreign substances from entering the interior of the electronic device. For example, the at least one protrusion positioned at the fourth position (a4) may increase the time required for foreign substances to reach the interior of the electronic device. However, the present invention is not limited thereto. For example, the protrusion may not be positioned at the fourth position (a4).

[0208] According to one embodiment, the first line (L1) and the second line (L2) may be virtual lines formed based on angles with high usage when the state of the electronic device changes. In one example, the first angle (for example, the first angle of FIG. 20) when the first end (531) of the third housing (530) is arranged on the first line (L1) may be about 32.5 degrees. In one example, the first angle (for example, the first angle of FIG. 20) when the first end (531) of the third housing (530) is arranged on the first line (L1) may be about 52.5 degrees. However, the present invention is not limited thereto.

[0209] According to one embodiment, the third position (a3) ​​may include a position where the gap between the second hinge housing (590) and the first end (531) of the third housing (530) is minimized when the state of the electronic device changes from an unfolded state to a state where the first end (531) of the third housing (530) moves to the first line (L1).

[0210] According to one embodiment, the second position (a2) may include a position at which the gap with respect to the second hinge housing (590) is minimized when the state of the electronic device changes from a state in which the first end (531) of the third housing (530) has moved to the first line (L1) to a state in which the first end (531) of the third housing (530) has moved to the second line (L2). That is, if the electronic device is often in an intermediate state at a specific angle between an unfolded state and a folded state, the second position (a2) may be selected as a position at which the gap with respect to the hinge housing is the smallest based on the electronic device being in the intermediate state at a specific angle, for example, at a specific angle that is most frequently used.

[0211] According to one embodiment, the first position (a1) may include a position where the gap between the second hinge housing (590) and the state of the electronic device is minimized when the state of the first end (531) of the third housing (530) changes to a folded state by moving to the second line (L2).

[0212] FIG. 25 is a drawing illustrating a protrusion including a curved surface according to one embodiment.

[0213] The configuration of Figure 25 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.

[0214] Referring to FIG. 25, edges of a plurality of protrusions (1120) according to one embodiment may include a curved surface having a curvature. For example, at least one edge of the first protrusion (1121), the second protrusion (1122), or the third protrusion (1123) may include a curved surface having a curvature. For example, a first edge of the first protrusion (1121) facing the second protrusion (1122) may include a first curved surface (1121a) having a first curvature. A second edge of the first protrusion (1121), opposite to the first edge, may include a second curved surface (1121b) having a second curvature. In one example, the second curvature may be greater than the first curvature.

[0215] According to one embodiment, since the edges of the plurality of protrusions (1120) include curved surfaces having a curvature, foreign substances placed on the plurality of protrusions (1120) can easily move between the plurality of protrusions (1120). Since the edges of the plurality of protrusions (1120) include curved surfaces having a curvature, scratches on the second hinge housing (e.g., the second hinge housing (590) of FIG. 24) or damage to the second hinge housing by foreign substances placed on the plurality of protrusions (1120) can be prevented or reduced. For example, since the edges of the first protrusions (1121) include curved surfaces, foreign substances placed on the first protrusions (1121) can easily move to the outside of the third housing (630) and / or to the space (e.g., groove) between the first protrusions (1121) and the second protrusions (1122). Although only the third housing (630) is illustrated in FIG. 25, the information regarding the second housing can be referenced by the information regarding the third housing (630).

[0216] FIG. 26 is a drawing for explaining a plurality of protrusions including a curved surface having a curvature according to one embodiment.

[0217] The configuration of Figure 26 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.

[0218] Referring to FIG. 26, according to one embodiment, a first edge of a first protrusion (1121) facing a second protrusion (1122) may include a first curved surface (1121a) having a first curvature (R1). A second edge opposite the first edge of the first protrusion (1121) may include a second curved surface (1121b) having a second curvature (R2). In one example, the second curvature (R2) may be smaller than the first curvature (R1).

[0219] In one embodiment, the curvature of the edge facing the first protrusion (1121) of the protrusion may be greater than the curvature of the edge facing the opposite direction of the first protrusion (1121). In one example, the third edge of the second protrusion (1122) facing the first protrusion (1121) may include a third curved surface (1122a) having a third curvature (R3). The fourth edge of the second protrusion (1122), opposite the third edge, may include a fourth curved surface (1122b) having a fourth curvature (R4). In one example, the fourth curvature (R4) may be less than the third curvature (R3). In one example, the fifth edge of the third protrusion (1123) facing the second protrusion may include a fifth curved surface (1123a) having a fifth curvature (R5). A sixth edge opposite the fifth edge of the third protrusion (1123) may include a sixth surface (1123b) having a sixth curvature (R6). In one example, the sixth curvature (R6) may be smaller than the fifth curvature (R5).

[0220] In one embodiment, the curvature of the edge of the plurality of protrusions facing in the opposite direction of the first protrusion (1121) may gradually decrease as it faces in the opposite direction. In one example, the third curvature (R3) may be greater than the fifth curvature (R5).

[0221] Fig. 27 is a drawing for explaining the shape of a protrusion according to one embodiment.

[0222] The configuration of Figure 27 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.

[0223] Referring to FIG. 27, the plurality of protrusions (1130) according to one embodiment may include concave portions. For example, the plurality of protrusions (1130) may include concave portions formed in a direction facing the inside of the plurality of protrusions (1130).

[0224] According to one embodiment, the plurality of protrusions (1130) may include a first portion (1131) and a second portion (1132) disposed closer to a second hinge housing (e.g., the second hinge housing (590) of FIG. 24) than the first portion (1131). The first portion (1131) may be disposed closer to the third housing (730) than the second portion (1132). In one example, the first portion (1131) may be a portion formed by a concave portion. In one example, the width of the first portion (1131) may be less than or equal to the width of the second portion (1132).

[0225] In this disclosure, the content of the third housing may be referenced by the second housing, and the content of the second housing may be referenced by the content of the third housing. For example, although only the third housing (730) is illustrated in FIG. 27, the content of the third housing (730) may be referenced by the second housing.

[0226] Fig. 28 is a drawing for explaining the shape of a protrusion according to one embodiment.

[0227] The configuration of Figure 28 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.

[0228] Referring to FIG. 28, a plurality of protrusions (1140) according to one embodiment may include a first portion (1141) and a second portion (1142) disposed closer to a second hinge housing (e.g., the second hinge housing (590) of FIG. 24) than the first portion (1141). The first portion (1141) may be disposed closer to the third housing (830) than the second portion (1142). In one example, the width of the first portion (1141) may be less than or equal to the width of the second portion (1142).

[0229] For example, the plurality of protrusions (1140) may have a trapezoidal shape. For example, the width of the plurality of protrusions (1140) may gradually decrease as they face in the direction (e.g., the -z direction) from the second hinge housing (e.g., the second hinge housing (590) of FIG. 24) toward the third housing (830). However, the present invention is not limited thereto. For example, the plurality of protrusions (1140) may have at least one shape among an N-gonal shape (i.e., a polygonal shape with N edges), a circular shape, an irregular shape, or a rhombus shape. Although only the third housing (830) is illustrated in FIG. 28, the description of the third housing (830) may refer to the second housing.

[0230] FIG. 29 is a drawing illustrating a protrusion including a slope according to one embodiment.

[0231] The configuration of Figure 29 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 overlapping content is omitted.

[0232] Referring to FIG. 29, according to one embodiment, the second slope (1152) may be gentler than the first slope (1151). For example, the plurality of protrusions (1150) may include a first slope (1151) facing a space (S) between the second housing (e.g., the second housing (120) of FIG. 1) and the third housing (930) in an unfolded state (e.g., the unfolded state of FIG. 1) of the electronic device (e.g., the electronic device (10) of FIG. 1), and a second slope (1152) opposite to the first slope (1151). The first slope (1151) may form a first angle with the outer side (691) of the second hinge housing (690). The second inclined surface (1152) may form a second angle with the outer side (691) of the second hinge housing (690). In one example, the first angle may be greater than or equal to the second angle.

[0233] For example, the angle between the first inclined surface (1151) and the inner side of the third housing (930) may have a third angle. The angle between the second inclined surface (1152) and the inner side of the third housing (930) may have a fourth angle. In one example, the fourth angle may be greater than or equal to the third angle.

[0234] According to one embodiment, since the second slope (1152) is gentler than the first slope (1151), the first slope (1151) can prevent foreign substances (D) that have entered between the plurality of protrusions (1150) from entering the interior of the electronic device (e.g., in the -x direction). Since the second slope (1152) is gentler than the first slope (1151), the second slope (1152) can induce foreign substances (D) that have entered between the plurality of protrusions (1150) to move to the exterior of the electronic device (e.g., in the +x direction).

[0235] Figure 30 is a perspective view illustrating a bulkhead according to one embodiment.

[0236] The configuration of Fig. 30 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.

[0237] According to one embodiment, an electronic device (e.g., the electronic device (10) of FIG. 1) may include a plurality of partition walls (1170) arranged between a plurality of protrusions (1160). The plurality of partition walls (1170) may be arranged to at least partially block an area between the plurality of protrusions (1160). For example, the plurality of partition walls (1170) may be arranged along a direction substantially perpendicular to a longitudinal direction (e.g., a y-axis direction) of the plurality of protrusions (1160). However, the present invention is not limited thereto. For example, the plurality of partition walls (1170) may be arranged to form a predetermined angle with the longitudinal direction of the plurality of protrusions (1160).

[0238] According to one embodiment, the plurality of partition walls (1170) may be disposed in at least one of the second housing (1020) or the third housing (1030). For example, the plurality of partition walls (1170) may be formed in at least one of the second housing (1020) or the third housing (1030). In one example, the plurality of partition walls (1170) may be formed integrally with at least one of the second housing (1020) or the third housing (1030). In one example, the plurality of partition walls (1170) may be formed integrally with the plurality of protrusions (1160). In one example, the plurality of partition walls (1170) and the plurality of protrusions (1160) may be formed integrally with at least one of the second housing (1020) or the third housing (1030).

[0239] According to one embodiment, the plurality of partition walls (1170) may protrude from at least one of the second housing (1020) or the third housing (1030). For example, the plurality of partition walls (1170) may protrude from at least one of the inner side of the second housing (1020) or the inner side of the third housing (1030) in a direction toward the second hinge housing (e.g., the second hinge housing (690) of FIG. 29). In one example, the plurality of partition walls (1170) may face the outer side of the second hinge housing (e.g., the outer side (691) of FIG. 29). In one example, the plurality of partition walls (1170) may be arranged to be spaced apart from the outer side of the second hinge housing by a predetermined distance.

[0240] According to one embodiment, the height of the plurality of bulkheads (1170) may be substantially the same as the height of the plurality of protrusions (1160), but is not limited thereto.

[0241] According to one embodiment, the electronic device may include a plurality of bulkheads (1170) such that foreign matter introduced between the plurality of protrusions (1160) may be prevented or minimized from moving in the longitudinal direction (e.g., in the y-axis direction) of the protrusions (1160).

[0242] FIG. 31 is a perspective view illustrating side-by-side bulkheads according to one embodiment.

[0243] The configuration of Fig. 31 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.

[0244] Referring to FIG. 31, a plurality of partition walls (1170) according to one embodiment may include a first partition wall (1171) disposed between a first protrusion (1161) and a second protrusion (1162), and a second partition wall (1172) disposed between the second protrusion (1162) and the third protrusion (1163). In one example, the first partition wall (1171) may be disposed parallel to the second partition wall (1172). For example, when the electronic device (e.g., the electronic device (10) of FIG. 1) is viewed from the side (e.g., when viewed in the +x direction), the first partition wall (1171) and the second partition wall (1172) may overlap. For example, the first partition wall (1171) and the second partition wall (1172) may be disposed continuously. For example, the first bulkhead (1171) and the second bulkhead (1172) can be aligned in the same direction (e.g., in the x-axis direction).

[0245] According to one embodiment, the width of the first bulkhead (1171) may be substantially the same as the width of the second bulkhead (1172). For example, the width of the plurality of protrusions (1160) of the first bulkhead (1171) in the longitudinal direction (e.g., in the y-axis direction) may be substantially the same as the width of the plurality of protrusions (1160) of the second bulkhead (1172) in the longitudinal direction.

[0246] Figure 32 is a drawing for explaining the relationship between a bulkhead and a flexible circuit board according to one embodiment.

[0247] The configuration of Figure 32 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.

[0248] Referring to FIG. 32, an electronic device according to an embodiment (e.g., the electronic device (10) of FIG. 1) may include a flexible circuit board (1200) disposed above a plurality of protrusions (1160). When the electronic device is viewed from above, the flexible circuit board (1200) may at least partially correspond to the plurality of protrusions (1160). For example, the flexible circuit board (1200) may at least partially overlap the plurality of protrusions (1160).

[0249] According to one embodiment, the plurality of partition walls (1170) may be arranged to prevent or reduce foreign substances from outside the electronic device from entering a component (e.g., the flexible printed circuit board (1200) and / or the second hinge assembly) arranged inside the electronic device. For example, the plurality of partition walls (1170) may be arranged at a position to block foreign substances from outside the electronic device from entering a component (e.g., the flexible printed circuit board (1200) and / or the second hinge assembly) arranged inside the electronic device. For example, the plurality of partition walls (1170) may be arranged to form a predetermined angle with respect to the longitudinal direction of the plurality of protrusions (1160). For example, the plurality of partition walls (1170) may be arranged in a direction substantially perpendicular to the longitudinal direction of the plurality of protrusions (1160) (e.g., the x-axis direction). For example, when the electronic device is viewed from above, the plurality of partition walls (1170) may be arranged to sandwich the component. For example, referring to FIG. 32, when looking down at the electronic device from above, a flexible circuit board (1200) can be placed between a plurality of bulkheads (1170).

[0250] According to one embodiment, the plurality of partition walls (1170) may be arranged at positions spaced apart from the component by a predetermined distance. For example, the plurality of partition walls (1170) may be arranged at positions spaced apart from the component by a predetermined distance in the longitudinal direction (e.g., in the y-axis direction) of the plurality of protrusions (1160). In one example, the predetermined distance may be about 0.5 mm to 10 mm. However, the present invention is not limited thereto.

[0251] According to one embodiment, the plurality of protrusions (1160) may be substantially parallel to one another. For example, the plurality of protrusions (1160) may be arranged to face the same direction. For example, the plurality of protrusions (1160) may be aligned to face the same direction. However, this is not limited thereto.

[0252] According to one embodiment, the plurality of bulkheads (1170) may be substantially parallel to one another.

[0254] The configuration of Figure 33 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.

[0255] Referring to FIG. 33, a third partition wall (1271) according to an embodiment may be disposed between the first protrusion (1261) and the second protrusion (1262). A fourth partition wall (1272) may be disposed between the second protrusion (1262) and the third protrusion (1263). In one example, the third partition wall (1271) may have a sixth width (w6) in the longitudinal direction (e.g., the y-axis direction) of the plurality of protrusions (1260). The fourth partition wall (1272) may have a seventh width (w7) in the longitudinal direction. In one example, the sixth width (w6) and the seventh width (w7) may be different from each other. For example, the seventh width (w7) may be greater than the sixth width (w6). However, the present invention is not limited thereto.

[0256] According to one embodiment, the third bulkhead (1271) and the fourth bulkhead (1272) may at least partially correspond to each other. For example, the third bulkhead (1271) and the fourth bulkhead (1272) may at least partially overlap each other in a direction substantially perpendicular to the longitudinal direction (e.g., in the x-axis direction).

[0257] FIG. 34 is a drawing for explaining a protrusion arranged on a bulkhead according to one embodiment.

[0259] According to one embodiment, an electronic device (e.g., the electronic device (10) of FIG. 1) may include a plurality of protrusions (1180) arranged on a plurality of partition walls (1170). For example, the plurality of protrusions (1180) may be arranged on the plurality of partition walls (1170). For example, the plurality of protrusions (1180) may be arranged on the plurality of partition walls (1170). For example, referring to FIG. 34, a first protrusion (1181) may be arranged on a first partition wall (1171) arranged between a first protrusion (1161) and a second protrusion (1162). A second protrusion (1182) may be arranged on a second partition wall (1172) arranged between a second protrusion (1162) and a third protrusion (1163). The number of the plurality of protrusions is not limited to that illustrated in FIG. 34. For example, the electronic device may omit at least one protrusion or may include at least one additional protrusion.

[0260] According to one embodiment, a plurality of protrusions (1180) may protrude from a plurality of partition walls. For example, a first protrusion (1181) may protrude from a first partition wall (1171). For example, the first protrusion (1181) may protrude from the first partition wall (1171) in a direction in which the first partition wall (1171) protrudes (e.g., in the +z direction). A second protrusion (1182) may protrude from the second partition wall (1172). For example, the second protrusion (1182) may protrude from the second partition wall (1172) in a direction in which the second partition wall (1172) protrudes (e.g., in the +z direction).

[0261] According to one embodiment, the height of the first protrusion (1181) may be substantially the same as the height of the second protrusion (1182), but is not limited thereto.

[0262] According to one embodiment, the plurality of protrusions (1180) can maintain a distance between the second hinge housing (e.g., the second hinge housing (690) of FIG. 29) and the plurality of bulkheads (1170).

[0263] According to one embodiment, the plurality of protrusions (1180) may include a polymer material such as rubber or silicone. For example, the plurality of protrusions (1180) may include polyurethane (PU). However, the present invention is not limited thereto. For example, the plurality of protrusions (1180) may include elastic bodies of various materials that are bendable. In one embodiment, the plurality of protrusions (1180) may include a polymer material such as polyethylene terephthalate (PET), polyurethane (PU), or thermoplastic polyurethane (TPU).

[0264] According to one embodiment, the plurality of protrusions (1180) are made of a soft material and can smoothly move relative to the second hinge housing when the state of the electronic device changes. Accordingly, the plurality of protrusions (1180) can prevent or reduce driving failure due to overlap between the plurality of protrusions (1180) and the second hinge housing.

[0265] Figure 35 is a drawing for explaining a bulkhead and a flexible circuit board according to one embodiment.

[0266] The configuration of Figure 35 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 overlapping content is omitted.

[0267] Referring to FIG. 35, an electronic device (e.g., the electronic device (10) of FIG. 1) may include a first partition wall (1371) and a second partition wall (1372) positioned between a first protrusion (1361) and a second protrusion (1362). However, the present invention is not limited thereto. For example, the electronic device may further include at least one partition wall. For example, the electronic device may further include a third partition wall (1373) and a fourth partition wall (1374) positioned between the second protrusion (1362) and the third protrusion (1363).

[0268] In one embodiment, the first bulkhead (1371) may protrude from the side of the first protrusion (1361). The second bulkhead (1372) may protrude from the side of the second protrusion (1362). In one embodiment, the first bulkhead (1371) may face the second bulkhead (1372). For example, the first bulkhead (1371) may protrude in a direction toward the second protrusion (1362), and the second bulkhead (1372) may protrude in a direction toward the first protrusion (1361).

[0269] In one embodiment, the first bulkhead (1371) and the second bulkhead (1372) may be spaced apart from each other. In one example, foreign matter may move between the first bulkhead (1371) and the second bulkhead (1372).

[0270] According to one embodiment, a plurality of partition walls (1370) may be arranged to prevent or reduce foreign substances from the outside of the electronic device from entering a component (e.g., the flexible printed circuit board (1300) and / or the second hinge assembly) disposed inside the electronic device and to discharge foreign substances in an opposite direction of the component. For example, the first partition wall (1371) and the second partition wall (1372) may be arranged to face an opposite direction (e.g., the -y direction) of the component (e.g., the flexible printed circuit board (1300)). For example, the first partition wall (1371) may be arranged to form a predetermined angle with the first protrusion (1361). The second partition wall (1372) may be arranged to form a predetermined angle with the second protrusion (1362). In one example, the first protrusion (1361) and the second protrusion (1362) may be arranged to form a predetermined angle. The foreign matter between the plurality of protrusions (1360) may be restricted from moving in a direction toward a component (e.g., a flexible circuit board (1300)) by the plurality of partition walls (1370). The foreign matter between the plurality of protrusions (1360) may be induced to move in an opposite direction of the component by the plurality of partition walls (1370). For example, the foreign matter between the plurality of protrusions (1360) may be easily moved in an opposite direction of the component by the plurality of partition walls (1370). For example, the foreign matter between the plurality of protrusions (1360) may be easily moved in the -y direction while being prevented or hindered from moving in the +y direction by the plurality of partition walls (1370).

[0306] According to one embodiment, the first anti-vibration member may be different from the second anti-vibration member.

[0307] According to one embodiment, at least one of the plurality of second anti-vibration members may include at least one of a protrusion, a sweeper, a brush, or a sealing member.

[0308] According to one embodiment, the plurality of second anti-vibration members may be arranged in the longitudinal direction of the second hinge housing and may be spaced apart from the outer side of the second hinge housing by a predetermined distance.

[0309] According to one embodiment, in the unfolded state of the electronic device, the first housing and the second housing may be arranged to cover the first hinge housing, and the second housing and the third housing may be arranged to cover a portion of the second hinge housing.

[0310] In addition to the foregoing description, the following enumerated aspects 1 to 15 are relevant to the present disclosure:

[0311] Mode 1: An electronic device may include a foldable housing including a first housing, a second housing, and a third housing; a first hinge structure rotatably connecting the first housing and the second housing; a second hinge structure rotatably connecting the second housing and the third housing; a first hinge housing covering at least a portion of the first hinge structure; a second hinge housing covering at least a portion of the second hinge structure and having a wider width than the first hinge housing; and a plurality of protrusions disposed on at least one of an inner surface of the second housing (e.g., an inner surface (120a) of FIG. 10) or an inner surface of the third housing (e.g., an inner surface (130a) of FIG. 10)) and protruding in a direction toward the second hinge housing in an unfolded state of the electronic device.

[0312] This has the advantage of effectively preventing foreign matter from entering the device and causing damage. In particular, it has the advantage of preventing foreign matter from entering the wide hinge structure that enables multiple folding (folding the device more than twice) when, for example, the gap between the second hinge housing and the second and / or third housings changes during the device's folding operation.

[0313] Aspect 2: In the electronic device of aspect 1, the plurality of protrusions are formed to be substantially parallel to the longitudinal direction of the second hinge housing.

[0314] Advantageously, the protrusion's ability to prevent foreign matter from entering is optimized.

[0315] Aspect 3: In the electronic device of aspect 1 or 2, the plurality of protrusions include a first protrusion, a second protrusion, and a third protrusion, and are sequentially arranged in a direction from a second end of the third housing overlapping the second hinge housing toward the second end of the third housing.

[0316] Aspect 4: In any one of the electronic devices of aspects 1 to 3, the first protrusion has a first height from the inner surface of the third housing in the direction of the second hinge housing, the second protrusion has a second height from the inner surface of the third housing in the direction of the second hinge housing, the third protrusion has a third height from the inner surface of the third housing in the direction of the second hinge housing, and the first height is higher than or equal to the second height and the third height.

[0317] Accordingly, the first protrusion effectively prevents foreign matter from entering, especially when the device is closed (folded), and the first protrusion is the main or only protrusion preventing the intrusion, and further, during the folding operation of the device, a gap / distance between the first protrusion and the second hinge housing changes or increases (e.g., the gap increases compared to when the device is fully closed (and / or fully opened)). In addition, additional protrusions having different heights are advantageous in that foreign matter entering the device moves in a desired direction, for example, out of the device or out of an area in contact with a display surface of the device, thereby preventing scratches.

[0318] Aspect 5: In any one of the electronic devices of aspects 1 to 4, a first gap between the first protrusion and the second protrusion is greater than or equal to a second gap between the second protrusion and the third protrusion.

[0319] This has the advantage of preventing intruding debris from abrading the hinge housing. Specifically, when potential foreign matter sequentially enters and potentially passes through protrusions and gaps / grooves, larger foreign matter can be effectively trapped without abrading in the first groove / gap, compared to smaller foreign matter trapped in successive gaps / grooves. In other words, the movement of foreign matter entering the device can be facilitated in the desired direction.

[0320] Aspect 6: The electronic device of any one of aspects 1 to 5 further includes a first groove formed between the first protrusion and the second protrusion, and a second groove formed between the second protrusion and the third protrusion, wherein the first groove has a first depth in a direction opposite to a direction in which the plurality of protrusions protrude, and the second groove has a second depth in a direction opposite to a direction in which the plurality of protrusions protrude, and wherein the first depth is greater than or equal to the second depth.

[0321] This has the advantage of allowing the infiltrating foreign matter to better settle into the first groove space, minimizing further infiltration of foreign matter and minimizing friction. In other words, it facilitates the movement of foreign matter infiltrating the device in the desired direction.

[0322] The benefits of mode 5 can be understood to also apply to mode 6, and vice versa.

[0323] Embodiment 7: In any one of the electronic devices of Embodiments 1 to 6, the periphery of the third housing includes a first protrusion.

[0324] Advantageously, ingress protection is further improved. In particular, the placement of protrusions around the perimeter effectively prevents the ingress of foreign substances in various (folded) configurations of the electronic device.

[0325] Aspect 8: In the electronic device of aspects 1 to 7, the edges of the plurality of protrusions include a curved surface having a curvature, wherein a first edge of a first protrusion facing a second protrusion includes a first curved surface having a first curvature, and wherein a second edge of the first protrusion opposite the first edge includes a second curved surface having a second curvature, and wherein the second curvature is less than the first curvature.

[0334] This has the advantage of controlling the direction of movement of foreign matter, for example encouraging foreign matter to move outwards rather than inwards.

[0335] Mode 13: The electronic device of any one of Modes 1 to 12 comprises a plurality of baffles disposed between the plurality of protrusions to at least partially block the area between the plurality of protrusions.

[0336] This has the advantage of improving the reliability of foreign body intrusion prevention and preventing foreign body intrusion in a direction essentially perpendicular to the longitudinal direction of the protrusion (and ultimately the hinge assembly or hinge housing).

[0337] Aspect 14: The electronic device of any one of aspects 1 to 13 includes a convex portion disposed between the second housing and the third housing in an unfolded state of the electronic device, wherein the convex portion protrudes from the outside of the second hinge housing so as to block at least one of a gap between the second housing and the second hinge housing or a gap between the third housing and the second hinge housing.

[0338] This is an improvement to the hinge housing, which allows the use of an additional convex portion in addition to the multiple protrusions, which has the advantage of further preventing foreign substances from entering the device and causing damage.

[0339] Aspect 15: In any one of the electronic devices of aspects 1 to 14, the width of the second hinge structure is greater than the width of the first hinge structure.

[0340] Advantageously, it is multi-foldable, and has the advantage of providing a device in a larger unfolded form or a smaller folded form through a folding action.
