The interlocking structure 407 may include, for example, a driving pulley 471a, a driven pulley 471b, and/or a driving belt 471c. In one embodiment, the driving pulley 471a may be disposed at one or both ends of the guide roller 261 to rotate together with the guide roller 261 . The driven pulley 471b may be provided at one or both ends of the rotating brush 263 to rotate together with the rotating brush 263 . In some embodiments, the drive belt 471c may be arranged such that the drive pulley 471a and the driven pulley 471b rotate in the same direction. For example, when the driving pulley 471a rotates, the driven pulley 471b may rotate in the same direction as the driving pulley 471a by the driving belt 471c. Accordingly, when the flexible display 203 is accommodated in the second housing 402 (eg, the second housing 202 of FIGS. 2 to 6 ) or is withdrawn to the outside, the guide roller 261 is the flexible display 203 . may be guided in the moving direction, and the rotating brush 263 may rub against the moving direction of the flexible display 203 in a reverse direction.

According to various embodiments, when the flexible display 203 moves in the receiving direction, the rotating brush 263 may rub against the flexible display 203 in a reverse direction (eg, an extension direction) while rotating. For example, when the flexible display 203 moves in the receiving direction, foreign substances attached to the flexible display 203 from the outside may be removed by the rotating brush 263 . In one embodiment, a tooth structure or a concave-convex structure is formed on the outer peripheral surface of the driving pulley 471a and the driven pulley 471b and/or the inner surface of the driving belt 471c, so that the driving pulley 471a and the driven pulley 471b) A rotation ratio of may be kept constant.

According to various embodiments, the electronic device 400 and/or the interlocking structure 407 may further include a lever member 477 , a stopper gear 473 and/or a ratchet structure 475 . , may be provided at both ends of the guide roller 261 and / or the rotary brush 263, respectively. The lever member 477 , the stopper gear 473 , and/or the ratchet structure 475 may optionally be configured according to a moving direction of the flexible display 203 or a rotating direction of the guide roller 261 , and optionally a rotating brush 263 . may be configured to separate from the flexible display 203 . For example, the rotating brush 263 is in contact with the flexible display 203 when the flexible display 203 moves in the receiving direction, and from the surface of the flexible display 203 when the flexible display 203 moves in the extending direction. can be separated. According to one embodiment, when the flexible display 203 moves in the receiving direction, the rotating brush 263 comes into contact with the flexible display 203 and rotates to prevent foreign substances from entering the inside of the second housing 402, When the flexible display 203 moves in the expansion direction, it is separated from the surface of the flexible display 203 to make the flexible display 203 move more smoothly. In some embodiments, if a foreign material already existing inside the second housing 402 is attached to the flexible display 203 , it does not interfere with the rotating brush 263 when moving in the expansion direction and is outside the second housing 402 . can be emitted as

According to various embodiments, the lever member 477 may be rotatably mounted on the second housing 402 to rotate about the rotation axis P. In one embodiment, the rotation axis (P) may be disposed substantially parallel to the rotation axis (R) at a position spaced apart from the rotation axis (R) of the guide roller (261). 9 is one of views for explaining the movement of the flexible display 203 in the receiving direction. Referring further to FIG. 9 , the lever member 477 is a rotating part 477a disposed on the rotation axis P. ), may include an interference portion 477b and a support portion 477c respectively extending or protruding from the rotating portion 477a. The rotating part 477a may be rotatably coupled to the second housing 402 to substantially provide a rotation center of the lever member 477 . In one embodiment, the interference portion 477b and the support portion 477c may extend or protrude from the rotating portion 477a in different directions. The interference portion 477b is, for example, at least partially disposed adjacent to one end of the guide roller 261 , and the rotating brush 263 may be rotatably coupled to the end of the support portion 477c.

According to various embodiments, as the lever member 477 rotates, the rotating brush 263 may contact the flexible display 203 or may be separated from the surface of the flexible display 203 . The interlocking structure 407 , for example, the lever member 477 is provided adjacent to both ends of the guide roller 261 , respectively, and may rotatably support both ends of the rotary brush 263 . In one embodiment, the lever member 477 is provided at both ends of the guide roller 261 , respectively, so that the rotating brush 263 is substantially parallel to the guide roller 261 in the operation of contacting or separating the flexible display 203 . can remain in one state.

According to various embodiments, the stopper gear 473 is disposed in the second housing 402 on at least one side of the guide roller 261 and may rotate with respect to the guide roller 261 . For example, when the guide roller 261 rotates, the stopper gear 473 may maintain a fixed state on the second housing 402 . In some embodiments, when the guide roller 261 rotates, the stopper gear 473 may rotate the lever member 477 while rotating in a specified angular range. For example, when the stopper gear 473 rotates the lever member 477 according to the rotation direction of the guide roller 261 , the rotation brush 263 may contact or be separated from the flexible display 203 .

According to various embodiments, the stopper gear 473 is a disk-shaped spur gear, and may interfere with the lever member 477, for example, the interference part 477b through the gear teeth formed on the outer surface. For example, when the stopper gear 473 rotates in a specified angular range, the gear teeth of the outer surface may interfere with the interference portion 477b to rotate the lever member 477 . In another embodiment, the ratchet structure 475 may be coupled to the guide roller 261 and at least partially received in the stopper gear 473 . In one embodiment, the ratchet structure 475 may include a ratchet pulley 475a rotatably coupled to the guide roller 261 and a ratchet lever 475b rotatably coupled to the ratchet pulley 475a. . A portion of the ratchet structure 475 , for example, at least the ratchet lever 475b may be substantially accommodated in the space formed by the stopper gear 473 . Although not given a reference number, ratchet protrusions arranged in a circumferential direction may be formed on the inner wall of the stopper gear 473 , and the ratchet lever 475b is in sliding contact with the ratchet protrusions according to the rotation direction of the guide roller 261 . or can be interlocked.

According to various embodiments, when the flexible display 203 moves in the receiving direction, the ratchet pulley 475a is rotated together with the guide roller 261 , and the ratchet lever 475b is a guide roller inside the stopper gear 473 . It can pivot around the axis of rotation (R) of 261. For example, the ratchet lever 475b may move inside the stopper gear 473 while in sliding contact with the ratchet protrusions. Taking the structure shown in FIG. 7 as an example, when the flexible display 203 moves in the receiving direction, the ratchet lever 475b may rotate around the rotation axis R in a clockwise direction. In some embodiments, when the flexible display 203 moves in the receiving direction, the stopper gear 473 tends to rotate in the same direction as the guide roller 261 due to sliding contact between the ratchet lever 475b and the ratchet protrusion. can For example, when the flexible display 203 moves in the receiving direction, the stopper gear 473 rotates the lever member 477 to bring the rotating brush 263 into contact with the flexible display 203 as shown in FIG. 7 . may have a tendency. In another embodiment, the driving belt 471c may have a certain amount of elasticity, and the rotating brush 263 may maintain a state in contact with the flexible display 203 by the elastic force of the driving belt 471c.

According to various embodiments, when the flexible display 203 moves in the expansion direction, the ratchet structure 475 may be substantially constrained by the stopper gear 473 . In one embodiment, the ratchet protrusions of the stopper gear 473 have a gear tooth shape with directionality, and when the flexible display 203 moves in the expansion direction, it engages the ratchet lever 475b to cause the ratchet lever 475b to rotate. It can be restrained from turning around. In some embodiments, since the ratchet structure 475 includes an elastic member, when the flexible display 203 moves in the expansion direction, the ratchet lever 475b may be maintained in engagement with any one of the ratchet protrusions. Accordingly, when engaged with the stopper gear 473, the ratchet pulley 475a and/or the ratchet lever 475b can rotate with respect to the stopper gear 473 together with the guide roller 261 in the operation in the receiving direction. However, it may be constrained by the stopper gear 473 in the operation in the expansion direction. When the flexible display 203 moves in the expansion direction while the ratchet pulley 475a and/or the ratchet lever 475b is constrained to the stopper gear 473, the guide roller 261 and the ratchet structure 475 (eg, : A friction force may occur between the ratchet pulleys (475a)). The friction force generated between the guide roller 261 and the ratchet structure 475 (eg, the ratchet pulley 475a) is a lever member through the ratchet structure 475 (eg, the ratchet lever 475b) and the stopper gear 473 . (477). 7 or 8, the frictional force generated between the guide roller 261 and the ratchet structure 475 may rotate the stopper gear 473 counterclockwise, and the lever member 477 ) may be rotated about the rotation shaft P according to the rotation of the stopper gear 473 to separate the rotation brush 263 from the flexible display 203 as shown in FIG. 8 .

Hereinafter, with further reference to FIGS. 9 to 12 , the movement of the flexible display 203 in the receiving direction or the expansion direction will be described in more detail. In the flexible display 203 , the second housing 402 (eg, the second housing 202 of FIGS. 2 to 6 ) includes the first housing (eg, the first housings 201 and 401 of FIGS. 2 to 8 ). ) may move on the second housing 402 in the receiving direction as it slides in the receiving direction. In another embodiment, when the second housing 402 slides from the first housing 401 to the withdrawal position, the flexible display 203 may move on the second housing 402 in an expansion direction.

9 to 11 show a flexible display 203 in an electronic device 400 (eg, the electronic devices 101, 102, 104, and 200 of FIGS. 1 to 6 ) according to various embodiments disclosed herein. 2 is a view sequentially illustrating a state accommodated inside the housing 402 (eg, the second housing 202 of FIGS. 2 to 6 ).

9 to 11 , when the flexible display 203 moves in the receiving direction, the flexible display 203 inside the second housing 402 (eg, the second area A2 of FIGS. 4 to 6 ) ) may move in the first direction M1, for example, the -X direction, and may move in the second direction while being deformed into a curved shape around the guide roller 261 . The movement of the flexible display 203 in the receiving direction may mean that the second area A2 of FIGS. 4 to 6 moves in the +X direction outside the second housing 402 . When the flexible display 203 moves in the receiving direction, the guide roller 261 rotates clockwise, for example, in the second direction M2, while the flexible display 203 and/or the articulated hinge structure 253 are rotated. can be guided in the direction of movement or transformed into a curved shape. In some embodiments, when the guide roller 261 rotates clockwise, for example, the flexible display 203 moves in the receiving direction (eg, in the first direction M1 inside the second housing 402 ). When moving, the ratchet structure (eg, the ratchet lever 475b) may rotate with respect to the stopper gear 473 while turning clockwise around the rotation axis R of the guide roller 261 .

According to various embodiments, when the guide roller 261 and/or the ratchet lever 475b rotates clockwise, an external force may not substantially act on the stopper gear 473 , and the rotating brush 263 is driven The belt 471c may rotate in the same direction as the guide roller 261 while maintaining the contact state with the flexible display 203 due to the elastic force of the belt 471c. For example, when the flexible display 203 moves in the receiving direction, the rotating brush 263 may rotate to generate a frictional force that moves the flexible display 203 in the expansion direction. Since it is made of a low-density elastic material or fiber, the rotating brush 263 removes foreign substances from the surface of the flexible display 203 , but may not substantially affect the movement of the flexible display 203 . In another embodiment, when the guide roller 261 and/or the ratchet lever 475b rotates clockwise, the ratchet lever 475b may be in sliding contact with the ratchet protrusions of the stopper gear 473 . Even if the ratchet lever 475b is in sliding contact with the ratchet protrusion, a frictional force sufficient to rotate the stopper gear 473 may not occur. In some embodiments, as the ratchet lever 475b rubs against the ratchet protrusion, the stopper gear 473 may have a tendency to rotate in a clockwise direction, for example, the second direction M2. When the stopper gear 473 has a tendency to rotate in the second direction M2 , a force for adhering the rotating brush 263 to the flexible display 203 may be generated. In some embodiments, if the rotating brush 263 is already in contact with the flexible display 203 with a specified amount of force, the interfering part 477b interferes with the stopper gear 473 to prevent the stopper gear 473 from rotating. can be limited For example, even if a rotational force is applied to the stopper gear due to rotation of the guide roller 261 in the second direction M2, the rotary brush 263 is already in contact or friction with the flexible display 203 to the extent that it can remove foreign substances. If there is, the lever member 477 may limit the rotation of the stopper gear 473 rather than bringing the rotating brush 263 into close contact with the flexible display 203 .

12 is a view showing the flexible display 203 in the second housing (eg, the electronic devices 101, 102, 104, and 200 of FIGS. 1 to 6) according to various embodiments disclosed herein. 402) (eg, the second housing 202 of FIGS. 2 to 6 ) is a diagram for explaining an operation of gradually exposing to the outside.

Referring to FIG. 12 , when the flexible display 203 moves in the expansion direction, the second area (eg, the second area A2 of FIGS. 2 to 4 ) moves in the third direction inside the second housing 402 . (M3), for example, may move in the +X direction, and may move in the fourth direction M4, for example, counterclockwise while being deformed to a curved shape around the guide roller 261 . The movement of the flexible display 203 in the receiving direction may mean that the second area A2 of FIGS. 4 to 6 moves in the -X direction from the outside of the second housing 402 . When the flexible display 203 moves in the expansion direction, the guide roller 261 rotates in a counterclockwise direction, for example, along the fourth direction M4 while rotating the flexible display 203 and/or the multi-tubular hinge structure 253 . It can be guided in the direction of movement or transformed into a curved shape. When the guide roller 261 rotates counterclockwise, for example, when the flexible display 203 moves in the expansion direction (eg, the third direction M3 inside the second housing 202), the ratchet The lever 475b is constrained by the stopper gear 473 to rotate with respect to the guide roller 261 . “The ratchet lever 475b rotates” may mean to rotate around the rotation axis R of the guide roller 261 . For example, when the guide roller 261 rotates counterclockwise, the ratchet lever 475b interferes with the ratchet protrusion, so that the ratchet structure (eg, the ratchet structure 475 in FIG. 7 ) is substantially the stopper gear 473 ). is constrained to, and the guide roller 261 may rotate with respect to the ratchet structure 475 .

According to various embodiments, when the guide roller 261 rotates counterclockwise, the ratchet structure 475 (eg, the ratchet pulley 475a in FIG. 7 ) is moved by the ratchet lever 475b to the stopper gear 473 . When constrained to, frictional force may be generated between the guide roller 261 and the ratchet pulley (475a). The frictional force generated between the guide roller 261 and the ratchet pulley 475a may rotate the stopper gear 473 through the ratchet lever 475b in the fourth direction M4, for example, by a designated angle in the counterclockwise direction. . The angle range at which the stopper gear 473 rotates is, for example, approximately 1 degree to 5 degrees, and it may be interpreted that the stopper gear 473 is substantially fixed on the second housing 402 . As the stopper gear 473 rotates in the fourth direction M4, the lever member 477 may rotate clockwise about the rotation axis P, and the rotation brush by rotation of the lever member 477 263 may be separated from the surface of the flexible display 203 . For example, the frictional force between the guide roller 261 and the ratchet pulley 475a may be greater than the elastic force of the driving belt 471c. Even if separated from the surface of the flexible display 203 , the rotating brush 263 rotates in the same direction as the guide roller 261 by an interlocking structure (eg, pulleys 471a and 471b and/or driving belt 471c). can do. In some embodiments, when the movement of the flexible display 203 and the rotation of the guide roller 261 are stopped, the elastic force of the driving belt 471c may bring the rotating brush 263 into contact with the surface of the flexible display 203 again. there is.

Referring to FIG. 13 , when the flexible display 203 moves in the receiving direction (eg, the first direction M1 inside the second housing 402 of FIG. 9 ), the guide roller 261 moves the flexible display 203 . While rotating in a clockwise direction inside the , deformation or movement of the flexible display 203 may be guided. The rotating brush 263 is disposed substantially outside the flexible display 203 and rotates in the same direction as the guide roller 261 by an interlocking structure, for example, pulleys 471a and 471b and a driving belt 471c. , may rub against the outer surface of the flexible display 203 . For example, when the flexible display 203 moves in the receiving direction, if there is a foreign material D on the surface of the flexible display 203 , it may be removed by the rotating brush 263 . The interlocking structure is, for example, to rotate the driving pulley 471a provided on the guide roller 261 , the driven pulley 471b provided on the rotating brush 263 , and/or the pulleys 471a and 471b in the same direction. It may include a connecting drive belt 471c, and the pulleys 471a and 471b and/or the drive belt 471c include a toothed structure or a concave-convex structure, so that the driving pulley 471a and the driven pulley 471b are formed. The rotation ratio can be kept constant.

Referring to FIG. 15 , the scraper 565 may be disposed inside the second housing 502 . For example, foreign substances attached to the rotary brush 263 may enter the inside of the second housing 502 to a certain extent. The scraper 565 interferes with the rotating brush 263 inside the second housing 502, and foreign substances that have entered the inside of the second housing 502 are removed from the rotating brush 263 by the scraper 565. can For example, when the scraper 565 is disposed, the foreign material attached to the rotary brush 263 may no longer be introduced into the second housing 502 . In some embodiments, the space in which a portion of the flexible display 203 (eg, the second area A2 of FIGS. 3-6 ) in the second housing 502 is accommodated is at least partially defined by the scraper 565 . The scraper 565 may block a passage through which foreign substances may be introduced between the rotating brush 263 and the inner wall of the second housing 502 .
