[0045] According to one embodiment of the present disclosure, a foldable electronic device (100) may include a first housing (110), a second housing (120), a third housing (130), a first hinge structure (140), a second hinge structure (150), and a flexible display (160). The first hinge structure (140) may be disposed between the first housing (110) and the second housing (120). The first hinge structure (140) may rotatably connect the first housing (110) and the second housing (120).

[0046] According to one embodiment, a second hinge structure (150) may be disposed between a second housing (120) and a third housing (130). The second hinge structure (150) may rotatably connect the second housing (120) and the third housing (130). A flexible display (160) may be disposed in at least the first housing (110), the second housing (120), and the third housing (130).

[0047] According to one embodiment, the flexible display (160) may be positioned to cross at least a portion of the first hinge structure (140) and the second hinge structure (150).

For example, in the first state in which the foldable electronic device (100) is unfolded by the first hinge structure (140) and the second hinge structure (150), the first housing (110), the second housing (120), and the third housing (130) may be arranged substantially parallel to each other. For example, in the first state in which the foldable electronic device (100) is unfolded, the first region, the second region, and the third region of the flexible display (160) may be arranged substantially parallel to each other. For example, in a first state where the foldable electronic device (100) is unfolded, the first, second, and third regions of the flexible display (160) may be positioned to face a first direction (e.g., +z axis direction).

[0050] According to one embodiment of the present disclosure, the foldable electronic device (100) can be sequentially unfolded by the second hinge structure (150) and the first hinge structure (140). For example, the second housing (120) and the third housing (130) can be rotated by the second hinge structure (150). For example, the first housing (110) and the second housing (120) can be rotated by the first hinge structure (140).

[0051] According to one embodiment of the present disclosure, as the second housing (120) and the third housing (130) are rotated by the second hinge structure (150), the second region and the third region of the flexible display (160) may be arranged substantially parallel. For example, the second region and the third region may be arranged to face a first direction. For example, as the second housing (120) and the third housing (130) are rotated by the second hinge structure (150), the second region of the flexible display (160) may be moved away from the third region.

For example, the first region and the second region may be arranged to face a first direction. For example, as the first housing (110) and the second housing (120) are rotated by the second hinge structure (150), the first region of the flexible display (160) may be moved away from the second region.

[0053] According to one embodiment of the present disclosure, with reference to FIGS. 1 and 2, in a first state of a foldable electronic device (100), a first region, a second region, and a third region of a flexible display (160) may all be arranged to face a first direction.

[0054] FIG. 3 is a side view illustrating an example of a second state of a foldable electronic device including a plurality of hinge structures according to one embodiment. FIG. 4 is a perspective view illustrating an example of a second state of a foldable electronic device including a plurality of hinge structures according to one embodiment.

[0055] According to one embodiment of the present disclosure, with reference to FIGS. 3 and 4, a second state of the foldable electronic device (100) may include a state in which the foldable electronic device (100) is folded by a first hinge structure (140) and unfolded by a second hinge structure (150). The first housing (110) and the second housing (120) may be rotated by the first hinge structure (140). For example, when the foldable electronic device (100) is folded by the first hinge structure (140), the first housing (110) may overlap with the second housing (120). For example, as the foldable electronic device (100) is folded by the first hinge structure (140), a first region of the flexible display (160) may come closer to a second region. For example, when the foldable electronic device (100) is folded by the first hinge structure (140), the first region and the second region of the flexible display (160) may overlap. For example, the state in which the first region and the second region overlap may include a state in which the first region and the second region are positioned to face each other. For example, the state in which the first region and the second region overlap may include a state in which the first region is positioned to face the second direction (-z-axis direction) and the second region is positioned to face the first direction.

[0056] FIG. 5 is a side view illustrating an example of a third state of a foldable electronic device including a plurality of hinge structures according to one embodiment.

[0057] According to one embodiment of the present disclosure, with reference to FIGS. 5 and 6, a third state of a foldable electronic device (100) may include a state in which, in the second state, the foldable electronic device (100) is folded by a first hinge structure (140) and folded by a second hinge structure (150). For example, in the third state, a third housing (130) may be arranged to overlap with a first housing (110) and a second housing (120). For example, in the third state, the first housing (110), the second housing (120), and the third housing (130) may be arranged to overlap each other. For example, in the third state, a first region and a third region of a flexible display (160) may be arranged to face a first direction, and a second region may be arranged to face a second direction.

[0058] According to one embodiment of the present disclosure, in a third state, a second housing (120) may be positioned between the first housing (110) and the third housing (130). In a third state, as the foldable electronic device (100) is folded by the second hinge structure (150), the first housing (110) may be positioned or accommodated within the space formed between the second housing (120) and the third housing (130). To form a space in which the first housing (110) may be positioned or accommodated, the width of the second hinge structure (150) may be wider than the width of the first hinge structure. For example, by having a width of the second hinge structure (150) that is wider than the width of the first hinge structure (140), the radius of rotation of the second housing (120) or the third housing (130) by the second hinge structure (150) may be larger than the radius of rotation of the first housing (110) or the second housing (120) by the first hinge structure (140).

[0059] According to one embodiment of the present disclosure, the first housing (110) may include a sub-display (170). For example, the sub-display (170) may be placed on the side opposite to the side where the flexible display (160) of the first housing (110) is placed. In a third state of the foldable electronic device (100), the sub-display (170) placed in the first housing (110) may be placed to face a first direction.

A first insertion hole (321c) may be formed in a lower portion (e.g., the -y direction in FIG. 9) of the first arm (321), and a first shaft (331), which will be described later, may be inserted into the first insertion hole (321c) so that the first arm (321) and the first shaft (331) may be connected. As the first arm (321) and the first shaft (331) are connected, the first arm (321) may rotate about the rotation axis of the first shaft (331). The first cam portion (321a) is formed in an area adjacent to the first insertion hole (321c) and may be formed to protrude in the direction of the detent plate (341) (e.g., the +z direction in FIG. 9). The first cam portion (321a) may be formed in an uneven shape with a plurality of repeating peaks and valleys, and the first cam portion (321a) may be positioned to engage with the detent portion (341a) formed on the detent plate (341) to provide a detent sensation to the first arm portion (321). Additionally, the first cam portion (321a) is positioned to engage with the detent portion (341a) formed on the detent plate (341), thereby allowing the first arm portion (321) to be fixed at a specified rotation angle and / or a specified rotation angle range, and as a result, the movement of the foldable electronic device (100) can be fixed at a specified rotation angle and / or a specified rotation angle range (e.g., a range from 30° to 150°). The first support rib (321b) may be formed protruding from one area of ​​the first arm portion (321), and when the foldable electronic device (100) rotates from a folded state to an unfolded state, the support portion (350) can be moved upward (e.g., in the +y direction of FIG. 9). The first through hole (321d) may be formed in an area opposite to the area where the first insertion hole (321c) of the first arm (321) is formed (e.g., the +x direction area of ​​FIG. 9).The first fixing part (323) passing through the first slide hole (311b) can connect the first bracket (311) and the first arm (321) by passing through the first through hole (321d). According to one embodiment, a first washer (325) is fastened to one end of the first fixing part (323) passing through the first through hole (321d), so that the first fixing part (323) can be fixed to the first arm (321). Although not shown in the drawing, according to one embodiment, the first washer (325) may be fastened to the other end of the first fixing part (323), so that the first fixing part (323) can be fixed to the first bracket (311). Additionally, according to one embodiment, a protrusion is formed in one area of ​​the first bracket (311) (or the first arm (321)), and a coupling groove corresponding to the protrusion is formed in one area of ​​the first arm (321) (or the first bracket (311)), so that the first bracket (311) and the first arm (321) may be connected through the protrusion and the coupling groove described above. The first arm (321) connected to the first bracket (311) can rotate with respect to the first bracket (311) while sliding with respect to the first bracket (311) during the process of the foldable electronic device (100) rotating from a folded state to an unfolded state or from an unfolded state to a folded state.

[0076] In one example, the second arm (322) may include a second cam (322a), a second support rib (322b), a second insertion hole (322c), and a second through hole (322d). A second insertion hole (322c) may be formed in a lower portion (e.g., the -y direction in FIG. 9) of the second arm (322), and a second shaft (332) may be inserted into the second insertion hole (322c) so that the second arm (322) and the second shaft (332) may be connected. As the second arm (322) and the second shaft (332) are connected, the second arm (322) may rotate about the rotation axis of the second shaft (332). The second cam portion (322a) is formed in an area adjacent to the second insertion hole (322c) and may be formed to protrude in the direction of the detent plate (341) (e.g., the +z direction in FIG. 9). The second cam portion (322a) may be formed in an uneven shape with a plurality of repeating peaks and valleys similar to the first cam portion (321a), and the second cam portion (322a) may be positioned to engage with the detent portion (341b) formed on the detent plate (341) to provide a detent sensation to the second arm portion (322). Additionally, the second cam portion (322a) is positioned to engage with the detent portion (341b) formed on the detent plate (341), thereby allowing the second arm portion (322) to be fixed at a specified rotation angle and / or a specified rotation angle range (e.g., a rotation angle range of 30° to 150°), and as a result, the movement (or posture) of the foldable electronic device (100) can be fixed at the specified rotation angle and / or a specified rotation angle range. The second support rib (322b) may be formed protruding from one area of ​​the second arm portion (322), and when the foldable electronic device (100) rotates from a folded state to an unfolded state, the support portion (350) may be moved upward (e.g., in the +y direction of FIG. 9). The second through hole (322d) may be formed in the area opposite to the second insertion hole (322c).The second fixing part (324) passing through the second slide hole (312b) can connect the second bracket (312) and the second arm (322) by passing through the second through hole (322d). A second washer (326) is fastened to one end of the second fixing part (324) passing through the second through hole (322d), so that the second fixing part (324) can be fixed to the second arm (322). Although not shown in the drawing, according to one embodiment, the second washer (326) may be fastened to the other end of the second fixing part (324), so that the second fixing part (324) can be fixed to the second bracket (312). Additionally, according to one embodiment, a protrusion is formed in one area of ​​the second bracket (312) (or the second arm (322)), and a coupling groove corresponding to the protrusion is formed in one area of ​​the second arm (322) (or the second bracket (312)), so that the second bracket (312) and the second arm (322) may be connected through the protrusion and the coupling groove described above. The second arm (322) connected to the second bracket (312) can rotate with respect to a rotation axis different from that of the second bracket (312) during the process in which the foldable electronic device (100) rotates from a folded state to an unfolded state or from an unfolded state to a folded state.

[0077] According to one embodiment, the rotating structure (330) may include a first shaft (331) coupled with a first gear (331a), a second shaft (332) coupled with a second gear (332a), a first idler gear (333), a second idler gear (334), a shaft bracket (335), and a gear cover (336).

[0078] In one example, one end of the first shaft (331) is fastened to the shaft hole (313e) of the fixed bracket (313), and the other end of the first shaft (331) can pass through the first shaft insertion hole (335a) of the shaft bracket (335). A first arm (321) can be connected to one area of ​​the first shaft (331), and the first arm (321) can rotate with the first shaft (331) as a pivot axis.

[0079] In one example, the second shaft (332) may be positioned adjacent to the first shaft (331), and one end of the second shaft (332) may be fastened to the shaft hole (313e) of the fixed bracket (313), and the other end of the second shaft (332) may pass through the second shaft insertion hole (335b) of the shaft bracket (335). A second arm (322) may be connected to a portion of the second shaft (332), and the second arm (322) may rotate with the second shaft (332) as a pivot axis.

[0080] In one example, a first idler gear (333) and a second idler gear (334) may be positioned between a first gear (331a) coupled to a first shaft (331) and a second gear (332a) coupled to a second shaft (332). The first idler gear (333) and the second idler gear (334) may each be fastened to a plurality of gear holes (313d) of a fixed bracket (313), and the first idler gear (333) and the second idler gear (334) may rotate by meshing with each other, thereby allowing the first arm (321) and the second arm (322) to rotate at the same rotation angle. According to one embodiment, the first idler gear (333) can rotate in mesh with the first gear (331a) and the second idler gear (334), and the second idler gear (334) can rotate in mesh with the first idler gear (333) and the second gear (332a). As the first gear (331a), the second gear (332a), the first idler gear (333), and the second idler gear (334) described above rotate in mesh with each other at the same angle, the first shaft (331) and the second shaft (332) can rotate in opposite directions by the same angle of rotation. In one example, when the first shaft (331) rotates 30˚ in a counterclockwise direction (e.g., from the +x axis to the +y direction in FIG. 9), the second shaft (332) can rotate 30˚ in a clockwise direction (e.g., from the -x axis to the +y direction in FIG. 9). As the first shaft (331) and the second shaft (332) rotate at the same rotational angle, the first arm (321) and the second arm (322) connected to the first shaft (331) and the second shaft (332) can rotate at the same rotational angle.

[0081] In one example, the shaft bracket (335) may include a first shaft insertion hole (335a) into which a first shaft (331) is inserted and a second shaft insertion hole (335b) into which a second shaft (332) is inserted. The shaft bracket (335) may be placed within a hinge housing to support the first shaft (331) and the second shaft (332) inserted into the shaft bracket (335) through the first shaft insertion hole (335a) and the second shaft insertion hole (335b).

[0082] In one example, the gear cover (336) is inserted into the first shaft (331) and the second shaft (332) to protect the first gear (331a), the second gear (332a), the first idler gear (333), and the second idler gear (334). The gear cover (336) can prevent or reduce damage to the first gear (331a), the second gear (332a), the first idler gear (333), and the second idler gear (334) caused by external forces, and can prevent or reduce the ingress of foreign matter into the first gear (331a), the second gear (332a), the first idler gear (333), and the second idler gear (334).

[0083] According to one embodiment, the detent structure (340) may include a detent plate (341), a first spring (342), and a second spring (343).

[0084] In one example, a third shaft insertion hole (341c) into which a first shaft (331) is inserted may be formed in one area of ​​the detent plate (341), and a fourth shaft insertion hole (341d) into which a second shaft (332) is inserted may be formed in another area of ​​the detent plate (341). The detent plate (341) may be connected to the first shaft (331) and the second shaft (332) through the third shaft insertion hole (341c) and the fourth shaft insertion hole (341d). The detent plate (341) may include a first detent portion (341a) formed by protruding in the direction of the first cam portion (321a) of the first arm portion (321), and a second detent portion (341b) formed by protruding in the direction of the second cam portion (322a) of the second arm portion (322). The first detent portion (341a) and the second detent portion (341b) may be formed as an uneven structure in which at least one peak and a valley appear repeatedly. The first detent portion (341a) is positioned to engage with the first cam portion (321a) so that when the foldable electronic device (100) is in a folded or unfolded state, it can provide a detent sensation to the first arm portion (321) and fix the movement of the first arm portion (321) at a specified rotation angle. Similarly, the second detent portion (341b) is positioned to engage with the second cam portion (322a) so that when the foldable electronic device (100) is in a folded or unfolded state, it can provide a detent sensation to the second arm portion (322) and fix the movement of the second arm portion (322) at a specified rotation angle.

[0085] According to one embodiment, the pitch between peaks or valleys of the first detent portion (341a) is formed to be larger than the pitch between peaks or valleys of the first cam portion (321a), so that the first arm portion (321) can rotate within a specified rotational range even when the first detent portion (341a) and the first cam portion (321a) are engaged. However, the shape of the first detent part (341a) is not limited to the above-described embodiment, and according to one embodiment, the pitch between peaks or valleys of the first detent part (341a) may be formed to be the same as the pitch between peaks or valleys of the first cam part (321a), or the pitch between peaks or valleys of the first cam part (321a) may be formed to be larger than the pitch between peaks or valleys of the first detent part (341a).

[0086] Similarly, the pitch between peaks or valleys of the second detent part (341b) is formed to be larger than the pitch between peaks or valleys of the second cam part (322a), so that the second arm part (322) can rotate within a designated rotation range even when the second detent part (341b) and the second cam part (322a) are engaged. However, the shape of the second detent part (341b) is not limited to the above-described embodiment, and according to one embodiment, the pitch between peaks or valleys of the second detent part (341b) may be formed to be the same as the pitch between peaks or valleys of the second cam part (322a), or the pitch between peaks or valleys of the second cam part (322a) may be formed to be larger than the pitch between peaks or valleys of the second detent part (341b).

[0087] According to one embodiment, the first spring (342) may be positioned to wrap around a portion of the first shaft (331), and the second spring (343) may be positioned to wrap around a portion of the second shaft (332). The first spring (342) and the second spring (343) are positioned in a compressed state between the detent plate (341) and the shaft bracket (335) so as to bring the detent plate (341) into close contact with the first arm (321) and the second arm (322). As the detent plate (341) is brought into close contact with the first arm (321) and the second arm (322), the interlocking state between the first detent portion (341a) and the first cam portion (321a), and the interlocking state between the second detent portion (341b) and the second cam portion (322a) can be maintained.

[0088] According to one embodiment, when the peak of the first detent portion (341a) and the peak of the first cam portion (321a) or the peak of the second detent portion (341b) and the peak of the second cam portion (322a) come into contact due to the rotation of the first arm portion (321) and the second arm portion (322), the detent plate (341) moves in one direction (e.g., the +z direction in FIG. 9) of the first shaft (331) and the second shaft (332) so that the first cam portion (321a) and the first detent portion (341a) and / or the second cam portion (322a) and the second detent portion (341b) may be temporarily separated. As the detent plate (341) moves in one direction, the first spring (342) and the second spring (343) may be compressed. When the first arm (321) and the second arm (322) are rotated further by a predetermined angle, the detent plate (341) can be moved again in the direction of the first cam (321a) and / or the second cam (322a) by the elastic restoring force of the first spring (342) and the second spring (343). As a result, the first cam (321a) and the first detent part (341a), and the second cam (322a) and the second detent part (341b) are positioned in a re-engaged state, so that the engaged state between the first cam (321a) and the first detent part (341a), and between the second cam (322a) and the second detent part (341b) can be maintained.

[0089] According to one embodiment, a flat straight area may be formed in at least one region (e.g., a normal region) of the peak of the first cam portion (321a), the peak of the second cam portion (322a), the peak of the first detent portion (341a), and / or the peak of the second detent portion (341b). Similarly, a flat straight area may be formed in at least one region of the valley of the first cam portion (321a), the valley of the second cam portion (322a), the valley of the first detent portion (341a), and / or the valley of the second detent portion (341b). The straight area formed in the region of the peak and the straight area formed in the region of the valley described above may be formed substantially identically or similarly. As straight areas are formed in the peaks and valleys of the first cam portion (321a), the second cam portion (322a), the first detent portion (341a), and the second detent portion (341b), the movement of the first arm portion (321) and / or the second arm portion (322) can be fixed at a specified rotation angle (e.g., 30˚ or 60˚) and / or a specified rotation angle range (e.g., a rotation angle range of 30˚ to 150˚). As the movement of the first arm portion (321) and / or the second arm portion (322) is fixed at a specified rotation angle, the movement of the first housing (110) and the second housing (120) of the electronic device can be fixed at a specified rotation angle.

[0090] According to one embodiment, the support member (350) may be placed in the empty space between the first arm (321) and the second arm (322), and between the first shaft (331) and the second shaft (332). The support member (350) may support a portion of the flexible display (160) that is not supported by the first arm (321) and / or the second arm (322) when the foldable electronic device (100) is in an unfolded state. The above-described support member (350) may be moved upward (e.g., in the +y direction of FIG. 9) by a first support rib (321b) formed in a portion of the first arm (321) and a second support rib (322b) formed in a portion of the second arm (322). As an example, as the foldable electronic device (100) rotates from a folded state to an unfolded state, the first support rib (321b) and the second support rib (322b) may come into contact with a region of the support member (350), and as the first arm (321) and the second arm (322) rotate, the support member (350) may move upward (e.g., from the -y direction to the +y direction in FIG. 9) by the first support rib (321b) and the second support rib (322b).

[0091] According to one embodiment, the stopper (360) may be located at the bottom of the support member (350) (e.g., in the -y direction of FIG. 9). A fifth shaft insertion hole (360a) may be formed in one area of ​​the stopper (360), and a sixth shaft insertion hole (360b) may be formed in one area opposite the fifth shaft insertion hole (360a). The first shaft (331) and the second shaft (332) may be inserted through the fifth shaft insertion hole (360a) and the sixth shaft insertion hole (360b), and the first shaft (331), the second shaft (332), and the stopper (360) may be connected through the structure described above. A through hole (360c) may be formed in an upper area of ​​the stopper (360) (e.g., +y direction in FIG. 9), and a protruding area (351) of the support (350) may be inserted into the lower direction of the stopper (360) by passing through the through hole (360c).

[0092] According to one embodiment, a screw (362) may be coupled with a protruding area (351) inserted into the bottom of a stopper (360), and an elastic member (361) may be disposed between the screw (362) and the stopper (360). The elastic member (361) may be a spring as an example, but is not limited thereto. The elastic member (361) may come into contact with a portion of the stopper (360), and the elastic member (361) may be compressed as the support member (350) moves upward during the process of the foldable electronic device (100) rotating from a folded state to an unfolded state. Conversely, as the foldable electronic device (100) rotates from an unfolded state to a folded state, the support member (350) may move downward (e.g., in the -y direction of FIG. 9) by the elastic restoring force of the elastic member (361).

[0093] A hinge structure (300a or 300b) according to one embodiment may further include a first auxiliary member (363) and a second auxiliary member (364). The first auxiliary member (363) may be fastened to one end of a first shaft (331) adjacent to a shaft bracket (335), and the second auxiliary member (364) may be fastened to one end of a second shaft (332) adjacent to a shaft bracket (335). According to one embodiment, a third washer (331b) may be fastened to one end of the first shaft (331) so that the first shaft (331) can be fixed to the first auxiliary member (363). Similarly, a fourth washer (332b) may be fastened to one end of the second shaft (332) so that the second shaft (332) can be fixed to the second auxiliary member (364). According to one embodiment, a screw nut may be fastened to one end of the first shaft (331) so that the first shaft (331) is fixed to the first auxiliary member (363), or a screw nut may be fastened to one end of the second shaft (332) so that the second shaft (332) is fixed to the second auxiliary member (364).

[0094] The first auxiliary member (363) may include a third support rib (363a), and the third support rib (363a) may be formed protruding from one area of ​​the first auxiliary member (363). Similarly, the second auxiliary member (364) may include a fourth support rib (364a), and the fourth support rib (364a) may be formed protruding from one area of ​​the second auxiliary member (364). The first auxiliary member (363) may rotate at the same rotational angle as the first arm (321) through the first shaft (331), and the second auxiliary member (364) may rotate at the same rotational angle as the second arm (322) through the second shaft (332). The third support rib (363a) and the fourth support rib (364a) can move the support member (350) upward together with the first support rib (321b) of the first arm (321) and the second support rib (322b) of the second arm (322) when the electronic device rotates from a folded state to an unfolded state.
