Referring to fig. 8 and 9A in combination, fig. 8 is a schematic structural view of the hinge 50 shown in fig. 6, and fig. 9A is a schematic structural view of the hinge 50 shown in fig. 8 taken along A-A. The section taken along A-A passes through the first rotating member 35, the movable member 32, the seat 31 and the second rotating member 36.

Wherein, the first rotating member 35 and the second rotating member 36 are connected between the first base 311 and the movable member 32, and the third rotating member 37 and the fourth rotating member 38 are connected between the second base 312 and the movable member 32.

The plurality of first engaging teeth 3512 can engage with the plurality of second engaging teeth 3612, such that the rotation angle of the first rotating end 351 of the first rotating member 35 is the same as the rotation angle of the second rotating end 361 of the second rotating member 36, and the rotation direction of the first rotating end 351 of the first rotating member 35 is opposite to the rotation direction of the second rotating end 361 of the second rotating member 36, such that the rotation actions of the first rotating member 35 and the second rotating member 36 relative to the base 31 are kept synchronous, i.e., synchronously approaching each other or moving away from each other.

The third engaging teeth 3712 are capable of engaging with the fourth engaging teeth 3812, so that the rotation angle of the third rotating end 371 of the third rotating member 37 is the same as the rotation angle of the fourth rotating end 381 of the fourth rotating member 38, and the rotation actions of the third rotating member 37 and the fourth rotating member 38 relative to the base 31 are kept synchronous, i.e. are synchronously approaching or separating from each other.

Wherein, the first bump 3511 of the first rotating member 35 is slidably connected to the first sliding slot 321 of the movable member 32, and the second bump 3611 of the second rotating member 36 is slidably connected to the second sliding slot 322 of the movable member 32.

Referring to fig. 9A and 9B in combination, fig. 9B is a schematic view of the structure shown in fig. 9A when the foldable electronic device 100 is in a folded state.

When the foldable electronic device 100 is folded or unfolded, the first rotating end 351 rotates relative to the base 31, the second rotating end 361 rotates relative to the base 31, the sliding distance of the first protrusion 3511 relative to the first sliding slot 321 is not zero in the projection of the first plane 200, and the sliding distance of the second protrusion 3611 relative to the second sliding slot 322 is not zero in the projection of the first plane 200.

Illustratively, during movement of the foldable electronic device 100 from the flattened state to the folded state, the first rotating end 351 may rotate in a clockwise direction and the second rotating end 361 may rotate in a counterclockwise direction, i.e., the direction of rotation of the first rotating end 351 of the first rotating member 35 is opposite to the direction of rotation of the second rotating end 361 of the second rotating member 36.

When the foldable electronic device 100 is in the flattened state, that is, when the folding assembly 30 is in the flattened state, the first rotating member 35 and the second rotating member 36 are relatively unfolded and are respectively located at two sides of the base 31. When the foldable electronic device 100 is in the folded state, that is, when the folding assembly 30 is in the folded state, the first rotating member 35 and the second rotating member 36 are relatively folded and located on the same side of the base 31.

During movement of the foldable electronic device 100 from the flattened state to the folded state, that is, during movement of the folding assembly 30 from the flattened state to the folded state, the movable member 32 moves relative to the base 31 in a direction away from the first plane 200. The first plane 200 is the plane in which the flexible display screen 2 lies when the foldable electronic device 100 is in the flattened state. Conversely, during movement of the foldable electronic device 100 from the folded state to the flattened state, that is, during movement of the folding assembly 30 from the folded state to the flattened state, the movable member 32 moves relative to the base 31 in a direction approaching the first plane 200.

Wherein, the base 31 and the movable member 32 are slidably connected with the stopper 3113 through the third chute 303. The third sliding groove 303 may cooperate with the limiting structure to limit the sliding direction of the movable member 32, so as to smooth the movement of the movable member 32. For example, as shown in fig. 9A, the stopper 3113 may be located on the first base 311, the third chute 303 may be located on the movable member 32, and the stopper 3113 of the first base 311 is slidably mounted on the third chute 303 of the movable member 32. In other embodiments, the limiting block 3113 may also be located on the movable member 32, and the third chute 303 may also be located on the first base 311.

During the movement of the foldable electronic device 100 from the flattened state to the folded state, the movable member 32 moves away from the first plane 200 relative to the first base 311, and the third chute 303 of the movable member 32 moves away from the first plane 200 relative to the stopper 3113 of the first base 311. In the process of moving the foldable electronic device 100 from the folded state to the flattened state, the movable member 32 moves relative to the first base 311 in a direction approaching the first plane 200, and the third chute 303 of the movable member 32 moves relative to the stopper 3113 of the first base 311 in a direction approaching the first plane 200.

In the embodiment of the application, in the process of moving the movable member 32 relative to the first base 311, the stopper 3113 of the first base 311 slides along the third chute 303 of the movable member 32 to limit the moving path of the movable member 32 relative to the first base 311, so that the movable member 32 moves stably.

Referring to fig. 10, fig. 10 is a schematic diagram of the structure shown in fig. 9A in other embodiments.

For example, the slot wall of the third chute 303 may be provided with a damping structure, where the damping structure is configured to match the stopper 3113, and provide resistance to sliding of the stopper 3113 relative to the third chute 303, so as to provide resistance to movement of the movable member 32 relative to the base 31, and further provide damping feel to the unfolding and folding processes of the foldable electronic device 100.

For example, the damping structure may include a protrusion 3114, the protrusion 3114 and the stopper 3113 forming a cam structure. The protrusion 3114 can provide resistance to sliding of the limit block 3113 relative to the third chute 303.

In the embodiment of the present application, the movable member 32 is slidably connected to the first seat 311. When the foldable electronic device 100 is folded or unfolded, the first rotating member 35 and the second rotating member 36 can rotate relative to the first base 311, and the movable member 32 slides relative to the base 31. The above-described movement process will be described with reference to the accompanying drawings.

Referring to fig. 11 and 12 in combination, fig. 11 is a schematic perspective view of the structure shown in fig. 9A, and fig. 12 is a schematic view of the structure shown in fig. 11 when the foldable electronic device 100 is in a folded state. Fig. 11 and 12 illustrate the structures of the first and second rotating members 35 and 36 shielded by the movable member 32 by dotted lines so as to clearly show the positions of the first projection 3511 of the first rotating member 35 and the second projection 3611 of the second rotating member 36.

Wherein the first rotating end 351 rotates around the first rotating center 3510 relative to the first base 311, and the first protrusion 3511 of the first rotating member 35 is disposed offset from the first rotating center 3510 of the first rotating end 351. The second rotating end 361 rotates around the second rotating center 3610 relative to the first base 311, and the second bump 3611 is disposed offset from the second rotating center 3610 of the second rotating end 361. The projection of the first bump 3511 on the first plane 200 and the projection of the second bump 3611 on the first plane 200 are both located between the projection of the first center of rotation 3510 on the first plane 200 and the projection of the second center of rotation 3610 on the first plane 200. In the embodiment of the present application, "between the first rotation center 3510 and the second rotation center 3610" should be construed broadly, and "between the first rotation center 3510 and the second rotation center 3610" refers to not only the range in which the line between the first rotation center 3510 and the second rotation center 3610 is located, but also the range in which the line between the first rotation center 3510 and the second rotation center 3610 covers upward and downward, and may be regarded as "between the first rotation center 3510 and the second rotation center 3610".

During the movement of the foldable electronic device 100 from the flattened state to the folded state, that is, during the movement of the folding assembly 30 from the flattened state to the folded state, the first bump 3511 and the second bump 3611 drive the movable member 32 to move away from the first plane 200 relative to the first base 311. Specifically, the first rotating end 351 of the first rotating member 35 rotates in the clockwise direction, and the first bump 3511 rotates in the clockwise direction around the first rotating center 3510 with the rotation of the first rotating end 351. The first bump 3511 moves along the first sliding groove 321, and pushes the movable member 32 to move away from the first plane 200 relative to the first base 311. The second rotating end 361 of the second rotating member 36 rotates in the counterclockwise direction, and the second bump 3611 rotates in the counterclockwise direction around the second rotation center 3610 with the rotation of the second rotating end 361. The second bump 3611 moves along the second chute 322 and pushes the movable member 32 to move away from the first plane 200 relative to the first seat 311.

During the movement of the foldable electronic device 100 from the folded state to the flattened state, that is, during the movement of the folding assembly 30 from the folded state to the flattened state, the first bump 3511 and the second bump 3611 drive the movable member 32 to move toward the direction approaching the first plane 200 relative to the first base 311. Specifically, the first rotating end 351 of the first rotating member 35 rotates in the counterclockwise direction, and the first bump 3511 rotates in the counterclockwise direction around the first rotating center 3510 with the rotation of the first rotating end 351. The first bump 3511 moves along the first sliding groove 321, and pushes the movable member 32 to move towards the direction approaching the first plane 200 relative to the first base 311. The second rotating end 361 of the second rotating member 36 rotates in the clockwise direction, and the second bump 3611 rotates in the clockwise direction around the second rotation center 3610 with the rotation of the second rotating end 361. The second bump 3611 moves along the second chute 322 and pushes the movable member 32 to move towards the direction approaching the first plane 200 relative to the first seat 311.

For example, when the foldable electronic device 100 is in the flattened state, the centroid of the cross-section of the first bump 3511 may be located on the line between the first center of rotation 3510 and the second center of rotation 3610, or the first bump 3511 may be slightly offset from the line between the first center of rotation 3510 and the second center of rotation 3610. The centroid of the cross section of the second bump 3611 may be located on the line between the first rotation center 3510 and the second rotation center 3610, or the second bump 3611 may be slightly offset from the line between the first rotation center 3510 and the second rotation center 3610. In an embodiment of the present application, the cross section of the structure is the area where the planes of the structure intersect in a direction perpendicular to the length extension of the movable member 32.

In the embodiment of the present application, when the foldable electronic device 100 is in the flattened state, the centers of the cross-sections of the first bump 3511 and the second bump 3611 are disposed on the connection line between the first rotation center 3510 and the second rotation center 3610, and during the movement of the foldable electronic device 100 from the flattened state to the folded state, the first rotation end 351 of the first rotating member 35 rotates by substantially 90 °, so that the first bump 3511 moves unidirectionally along the first sliding slot 321; the second rotating end 361 of the second rotating member 36 rotates by substantially 90 °, and the second cam 3611 moves unidirectionally along the second chute 322.

In addition, the first bump 3511 moves unidirectionally along the first sliding groove 321, the second bump 3611 moves unidirectionally along the second sliding groove 322, and the moving distance of the first bump 3511 can be limited by limiting the size of the first sliding groove 321, thereby limiting the rotating angle of the first rotating end 351; and the movement distance of the second bump 3611 is limited by limiting the size of the second chute 322, so as to limit the rotation angle of the second rotating end 361, and further limit the angle at which the first casing 10 and the second casing 20 can be opened relatively, that is, limit the opening angle of the casing device 1, thereby improving the reliability of the casing device 1.

For example, during the folding or unfolding process of the foldable electronic device 100, the projection of the first bump 3511 along the sliding path of the first chute 321 on the first plane 200 is parallel to the first direction X1, and the projection of the second bump 3611 along the sliding path of the second chute 322 on the first plane 200 is parallel to the first direction X1.

In other embodiments, the movable member 32 may be provided with a first slide slot 321 extending along the first direction X1. The first bump 3511 and the second bump 3611 are both slidably mounted on the first chute 321 of the movable member 32.

The arrangement position of the third bump of the third rotating member 37 may refer to the arrangement position of the first bump 3511 of the first rotating member 35, and the arrangement position of the fourth bump of the fourth rotating member 38 may refer to the arrangement position of the second bump 3611 of the second rotating member 36. The third protrusion of the third rotating member 37 and the fourth protrusion of the fourth rotating member 38 may be slidably mounted on the movable member 32, and the mounting structures of the third protrusion of the third rotating member 37 and the fourth protrusion of the fourth rotating member 38 and the movable member 32 may refer to the mounting structures of the first protrusion 3511 of the first rotating member 35 and the second protrusion 3611 of the second rotating member 36 and the movable member 32, respectively, which are not described herein.

Referring to fig. 13 in combination, fig. 13 is a schematic view of the structure shown in fig. 11 in some other embodiments.

For example, the included angle between the first direction X1 and the third direction Y may be smaller than 90 °, that is, the sliding direction of the first direction X1 and the movable member 32 relative to the first seat 311 may not be perpendicular. The included angle between the second direction X2 and the third direction Y may be smaller than 90 °, that is, the sliding direction of the second direction X2 and the movable member 32 relative to the first base 311 may not be perpendicular.

In the present embodiment, during the folding or unfolding process of the foldable electronic device 100, the projection of the first bump 3511 along the sliding path of the first chute 321 on the first plane 200 is parallel to the first direction X1, and the projection of the second bump 3611 along the sliding path of the second chute 322 on the first plane 200 is parallel to the second direction X2.

For example, the first sliding groove 321 and the second sliding groove 322 may be symmetrically distributed. That is, the shapes of the projection areas of the first slide groove 321 and the second slide groove 322 on the plane perpendicular to the extending direction of the movable member 32 are in a symmetrical relationship. The first sliding groove 321 and the second sliding groove 322 are symmetrically distributed, so that the first sliding groove 321 and the second sliding groove 322 are symmetrically acted by the pushing of the first bump 3511 and the second bump 3611, and the stress of the movable piece 32 is balanced, and the movement of the movable piece 32 is stable and smooth.

Wherein the support surface 301 is a plane for providing a flat support environment for the flexible display screen 2. The appearance surface 302 may be an arc surface, so that the appearance of the foldable electronic device 100 is softer when folded, which meets the requirement of ergonomic design, and improves the holding comfort.

For example, the movable member 32 may be provided with a first mating surface 323, a second mating surface 324, a fifth mating surface 325, and a sixth mating surface 326 on both sides thereof, respectively. The first mating surface 323 and the second mating surface 324 may be located at the top end of the movable member 32.

The first mating surface 323 and the second mating surface 324 are respectively disposed on the first supporting bump 327 and the second supporting bump 328. The third and fourth support protrusions 329 and 330 are respectively located at both sides of the body 320 and protrude with respect to both sides of the body 320. The fifth mating surface 325 and the sixth mating surface 326 are provided on the third support bump 329 and the fourth support bump 330, respectively.

The section taken at B-B passes through the first rotating member 35, the first connecting member 39, the first supporting member 33, the movable member 32, the second supporting member 34, the second connecting member 40, and the second rotating member 36.

Wherein the first support member 33 is rotatably connected to the first rotating member 35 via a first connecting member 39, and the second support member 34 is rotatably connected to the second rotating member 36 via a second connecting member 40. Specifically, the first connection member 39 passes through the fifth mounting hole 3311 of the fifth connection end 331 of the first support member 33 (refer to fig. 15 in combination) and the first mounting hole 3521 of the first connection end 352 of the first rotation member 35 to coaxially rotate the fifth connection end 331 of the first support member 33 with the first connection end 352 of the first rotation member 35. The second connection member 40 passes through the sixth mounting hole 3411 (see fig. 15) of the sixth connection end 341 of the second support member 34 and the second mounting hole 3621 of the second connection end 362 of the second rotation member 36 to coaxially rotate the sixth connection end 341 of the second support member 34 with the second connection end 362 of the second rotation member 36.

Wherein, the seventh mounting hole 3312 (refer to fig. 15 in combination) of the fifth connection end 331 of the first support 33 is rotatably connected to the third mounting hole 3721 of the third connection end 372 of the third rotation member 37 through the third connection member 41.

The eighth mounting hole 3412 (see fig. 15 in combination) of the sixth connection end 341 of the second support 34 is rotatably connected to the fourth mounting hole 3821 of the fourth connection end 382 of the fourth rotation member 38 through the fourth connection member 42.

When the foldable electronic device 100 is in the flattened state, the first rotating member 35 and the second rotating member 36 are located on both sides of the movable member 32. The first support 33 and the second support 34 are located at both sides of the movable member 32. The upper surface of the first support member 33 and the upper surface of the second support member 34 are relatively unfolded, and the upper surface of the first support member 33 and the upper surface of the second support member 34 are approximately parallel to the support surface 301 of the movable member 32. The first movable end 332 of the first supporting member 33 and the second movable end 342 of the second supporting member 34 overlap on two sides of the movable member 32, respectively, and the first supporting member 33 and the second supporting member 34 are used together to support the flexible display screen 2. Specifically, the first supporting protrusion 327 of the movable member 32 is embedded in the first groove 335 (see fig. 17 and 18) of the first supporting member 33, and the first mating surface 323 of the movable member 32 contacts or abuts the third mating surface 333 of the first supporting member 33. The second supporting protrusion 328 of the movable member 32 is embedded in the third groove 345 (see fig. 17 and 18) of the second supporting member 34, and the second mating surface 324 of the movable member 32 contacts or abuts the fourth mating surface 343 of the first supporting member 33.

When the foldable electronic device 100 is in the folded state, the first rotating member 35 and the second rotating member 36 are located on the same side of the movable member 32, and the first supporting member 33 and the second supporting member 34 are located on the same side of the movable member 32. There is a distance between the first movable end 332 of the first support member 33 and the second movable end 342 of the second support member 34 and the movable member 32, i.e., a distance between the first mating surface 323 of the movable member 32 and the third mating surface 333 of the first support member 33, and a distance between the second mating surface 324 of the movable member 32 and the fourth mating surface 343 of the first support member 33.

During the movement of the foldable electronic device 100 from the flattened state to the folded state, the first rotating member 35 and the second rotating member 36 are relatively folded, the first supporting member 33 and the second supporting member 34 are relatively folded, and the movable member 32 moves away from the first plane 200 relative to the first base 311. The first support member 33 rotates clockwise about the first link member 39 relative to the first rotating member 35, and the first movable end 332 of the first support member 33 moves away from the movable member 32. The second support 34 rotates about the second link 40 in a counterclockwise direction relative to the second rotating member 36, and the second movable end 342 of the second support 34 moves away from the movable member 32.

During the movement of the foldable electronic device 100 from the folded state to the flattened state, the first rotating member 35 and the second rotating member 36 are relatively unfolded, the first supporting member 33 and the second supporting member 34 are relatively unfolded, and the movable member 32 moves toward the direction approaching the first plane 200 relative to the first seat 311. As the movable member 32 moves relative to the first base 311 in a direction approaching the first plane 200, the third mating surface 333 of the first supporting member 33 overlaps the first mating surface 323 of the movable member 32 and slides along the first mating surface 323, the first supporting member 33 rotates relative to the first rotating member 35 around the first connecting member 39 in a counterclockwise direction, and the fourth mating surface 343 of the second supporting member 34 overlaps the second mating surface 324 of the movable member 32 and slides along the second mating surface 324, and the second supporting member 34 rotates relative to the second rotating member 36 around the second connecting member 40 in a clockwise direction. In addition, the first mating surface 323 and the third mating surface 333 are both inclined surfaces.

When the foldable electronic device 100 is in the flattened state, the first support 33 and the second support 34 are unfolded with respect to the movable member 32, providing support for the flexible display screen 2.

Further, in moving the foldable electronic device 100 from the folded state to the flattened state, the movable member 32 pushes the first supporting member 33 to rotate by the engagement of the first engaging surface 323 and the third engaging surface 333, and pushes the second supporting member 34 to rotate by the engagement of the second engaging surface 324 and the fourth engaging surface 343. Since the first mating surface 323 is an inclined surface, the sliding process of the third mating surface 333 relative to the first mating surface 323 is smooth; and the second mating surface 324 is an inclined surface, and the sliding process of the fourth mating surface 343 relative to the second mating surface 324 is smooth, so that the rotation process of the first supporting member 33 and the second supporting member 34 is smooth and steady, and the movement process of the folding assembly 30 is smooth and steady, and the user experience is good.

Moreover, the first matching surface 323 and the third matching surface 333 are in slant matching, and the second matching surface 324 and the fourth matching surface 343 are in slant matching, so that the connection stability between the movable piece 32 and the first supporting piece 33 and the connection stability between the movable piece 32 and the second supporting piece 34 are high, and the movable piece 32 can provide more stable supporting force for the first supporting piece 33 and the second supporting piece 34, so that the first supporting piece 33 and the second supporting piece 34 are prevented from shaking relative to the movable piece 32, and the first supporting piece 33 and the second supporting piece 34 provide stable supporting for the flexible display screen 2.

Wherein, when the foldable electronic device 100 is in the flattened state, the third supporting protrusion 329 of the movable member 32 is embedded in the second groove 336 of the first supporting member 33, and the fifth mating surface 325 of the movable member 32 contacts or fits with the seventh mating surface 334 of the first supporting member 33. The fourth support tab 330 of the movable member 32 is inserted into the fourth recess 346 of the second support member 34 and the sixth mating surface 326 of the movable member 32 contacts or engages the eighth mating surface 344 of the second support member 34.

When the foldable electronic device 100 is in the folded state, a distance exists between the fifth mating surface 325 of the movable member 32 and the seventh mating surface 334 of the first supporting member 33, and a distance exists between the sixth mating surface 326 of the movable member 32 and the eighth mating surface 344 of the second supporting member 34.

The engagement between the second groove 336 of the first support 33 and the third support protrusion 329 of the movable member 32 may refer to the engagement between the first groove 335 of the first support 33 and the first support protrusion 327 of the movable member 32, the engagement between the seventh engagement surface 334 of the first support 33 and the fifth engagement surface 325 of the movable member 32 may refer to the engagement between the third engagement surface 333 of the first support 33 and the first engagement surface 323 of the movable member 32, the engagement between the fourth groove 346 of the second support 34 and the fourth support protrusion 330 of the movable member 32 may refer to the engagement between the third groove 345 of the second support 34 and the second support protrusion 328 of the movable member 32, and the engagement between the eighth engagement surface 344 of the second support 34 and the sixth engagement surface 326 of the movable member 32 may refer to the engagement between the fourth engagement surface 343 of the second support 34 and the second engagement surface 324 of the movable member 32, which will not be repeated here.

Referring to fig. 17, 18 and 19 in combination, fig. 19 is a schematic structural view of the structure shown in fig. 17 when the foldable electronic device 100 is in an intermediate state between a flattened state and a folded state. Fig. 19 illustrates a schematic view when the third mating surface 333 of the first support member 33 and the first mating surface 323 of the movable member 32 overlap, and the second mating surface 324 of the movable member 32 and the fourth mating surface 343 of the second support member 34 overlap.

When the foldable electronic device 100 is in the flattened state, the first rotating member 35 and the second rotating member 36 are located on both sides of the movable member 32. The first support 33 and the second support 34 are located at both sides of the movable member 32. The upper surface of the first rotating member 35 is approximately parallel to the upper surface of the first supporting member 33, and the upper surface of the second rotating member 36 is approximately parallel to the upper surface of the second supporting member 34. A non-zero included angle exists between the lower surface of the first support member 33 and the first limiting surface 353 of the first rotating member 35, and a non-zero included angle exists between the lower surface of the second support member 34 and the second limiting surface 363 of the second rotating member 36. The upper surface of the first support member 33 is the surface of the first support member 33 facing the flexible display screen 2, and the lower surface of the first support member 33 is the surface of the first support member 33 facing away from the flexible display screen 2. The upper surface of the second support 34 is the surface of the second support 34 facing the flexible display screen 2, and the lower surface of the second support 34 is the surface of the second support 34 facing away from the flexible display screen 2.

When the foldable electronic device 100 is in the folded state, the first rotating member 35 and the second rotating member 36 are located on the same side of the movable member 32, and the first supporting member 33 and the second supporting member 34 are located on the same side of the movable member 32. The upper surface of the first support 33 is inclined with respect to the upper surface of the first rotation member 35, and the upper surface of the second support 34 is inclined with respect to the upper surface of the second rotation member 36. The first limiting surface 353 of the first rotating member 35 contacts the lower side of the first supporting member 33, and the second limiting surface 363 of the second rotating member 36 contacts the lower side of the second supporting member 34. The lower side of the first support member 33 is the side of the first support member 33 facing away from the flexible display screen 2, and the lower side of the second support member 34 is the side of the second support member 34 facing away from the flexible display screen 2.

During the movement of the foldable electronic device 100 from the flattened state to the folded state, the first rotating member 35 and the second rotating member 36 are relatively folded, the first supporting member 33 and the second supporting member 34 are relatively folded, and the movable member 32 moves away from the first plane 200 relative to the first base 311. The first supporting member 33 rotates relative to the first rotating member 35, and the angle between the lower surface of the first supporting member 33 and the first limiting surface 353 of the first rotating member 35 decreases until the two contact. The second supporting member 34 rotates relative to the second rotating member 36, and the included angle between the lower surface of the second supporting member 34 and the second limiting surface 363 of the second rotating member 36 decreases until the two contact.

During the movement of the foldable electronic device 100 from the folded state to the flattened state, the first rotating member 35 and the second rotating member 36 are relatively unfolded, the first supporting member 33 and the second supporting member 34 are relatively unfolded, and the movable member 32 moves toward the direction approaching the first plane 200 relative to the first seat 311. The third mating surface 333 of the first supporting member 33 is overlapped to the first mating surface 323 of the movable member 32, and as the movable member 32 moves in a direction approaching the first plane 200, the third mating surface 333 slides along the first mating surface 323, the first supporting member 33 relatively rotates under the pushing of the movable member 32, the lower surface of the first supporting member 33 leaves the first limiting surface 353 of the first rotating member 35, and the included angle between the lower surface of the first supporting member 33 and the first limiting surface 353 of the first rotating member 35 increases. The fourth mating surface 343 of the second supporting member 34 is overlapped with the second mating surface 324 of the movable member 32, and as the movable member 32 moves in a direction approaching the first plane 200, the fourth mating surface 343 slides along the second mating surface 324, the second supporting member 34 relatively rotates under the pushing of the movable member 32, the lower surface of the second supporting member 34 leaves the second limiting surface 363 of the second rotating member 36, and the included angle between the lower surface of the second supporting member 34 and the second limiting surface 363 of the second rotating member 36 increases.

In the embodiment of the present application, during the process of moving the foldable electronic device 100 from the folded state to the flattened state, due to the limitation of the first limiting surface 353 of the first rotating member 35, the first movable end 332 of the first supporting member 33 maintains a certain inclination angle with respect to the fifth connecting end 331, and the first movable end 332 of the first supporting member 33 does not arbitrarily rotate around the fifth connecting end 331 and is far away from the movable member 32, so that the distance between the first movable end 332 of the first supporting member 33 and the movable member 32 is relatively short, and the third mating surface 333 of the first movable end 332 can be overlapped with the first mating surface 323 of the movable member 32. Due to the limitation of the second limiting surface 363 of the second rotating member 36, the second movable end of the second supporting member maintains a certain inclination angle with respect to the sixth connecting end 341, and the second movable end 342 of the second supporting member 34 does not rotate about the sixth connecting end 341 arbitrarily but is far away from the movable member 32, so that the distance between the second movable end 342 of the second supporting member 34 and the movable member 32 is relatively short, and the fourth mating surface 343 of the second movable end 342 can overlap with the second mating surface 324 of the movable member 32.
