Of course, the tooth ratios of the first linking member 37, the first gear 394, the second gear 396 and the second linking member 38 can be adjusted correspondingly according to actual design requirements. In addition, because the straight-tooth gear has a simple structure, the accuracy of the rotation angles of the first substrate unit 22 and the second substrate unit 23 can be easily calculated, so that the size is reduced in proportion, and the occupied space is reduced.

In addition, since the surrounding plate 412 partially covers the first linking member 37, the transmission unit 39 and the second linking member 38, it is possible to prevent debris or dust generated by friction from entering and affecting the rotation.

Referring to fig. 12 to 14, top views of the flexible screen 1 device converted from the flat state to the folded state are respectively shown, so as to provide a reference position of a cross-section line of a cross-sectional plane in different subsequent states.

Therefore, when a user manipulates the flexible electronic device from the flat state to the folded state, for example, by manipulating the first housing 221 (see fig. 1), when the first housing 221 and the second housing 231 are in the flat state and are adjacently disposed, as shown in fig. 15 and 16, when the first housing 221 is forced in the up-down direction D2, the first housing 221 will exert a force on the first inner support plate 223, the first outer support plate 224 and the first base 222, so that the first bracket unit 33 connected to the first base 222 pivots towards the second bracket unit 35, and during the pivoting process, as shown in fig. 16 to 18, due to the first height difference H1 (see fig. 9) between the first inner pivot end 334 and the first outer pivot end 338, the first inner fixing end 335 links the first fixing structure 343 to slide away from the first outer body 337, that is, the first moving structure 344 slides from the end close to the base 21 to the end close to the first base 222 (see fig. 15), and at the same time, the first base 222 is driven to slide away from the first inner support plate 223 by a distance d, as shown in fig. 19, that is, the first connecting rod 227 of the first inner support plate 223 slides from the corresponding first through hole 225 from the first flattened end 2251 to the first folded end 2252, in this case, the first inner support plate 223 moves to be close to the bottom wall of the first housing 221 guided by the first through hole 225. The distance d may be adjusted according to the size of the flexible screen 1, and is not limited in this embodiment.

Referring to fig. 20, when the first substrate unit 22 is forced upward in the up-down direction D2, the first substrate unit 22 will link the first support unit 33 (see fig. 16) to link the first link member 37, so that the first link member 37 links the transmission unit 39, and further links the second link member 38, so that the second link member 38 links the second support unit 35 (see fig. 16) to drive the second substrate unit 23, and thereby the second substrate unit 23 synchronously rotates upward in the up-down direction D2.

referring to fig. 15 and 16, when the second substrate unit 23 rotates in the up-down direction D2, the second housing 231 applies a force to the second inner support plate 233, the second outer support plate 234 and the second base 232 to pivot the second support unit 35 connected to the second base 232 toward the first support unit 33, and during the pivoting process, as shown in fig. 16 to 18, due to the second height difference H2 (see fig. 9) between the second inner pivot end 354 and the second outer pivot end 358, the second inner fixing end 355 drives the second fixing structure 363 to slide in a direction away from the second outer body 357, that is, the second moving structure 364 slides from the end close to the base 21 to the end close to the second base 232, and simultaneously drives the second base 232 to slide in a direction away from the second inner support plate 233 and is separated by the distance D, as shown in fig. 19, that is, the second link 237 of the second inner support plate 233 is slid from the second flattened end 2351 to the second folded end 2352 from the corresponding second through hole 235, in this case, the second inner support plate 233 moves close to the bottom wall of the second housing 231 guided by the second through hole 235. Thereby, the first substrate unit 22 and the second substrate unit 23 are changed from the flat state to the folded state, and a space 25 is formed between the first substrate unit 22 and the second substrate unit 23 as shown in fig. 19.

In addition, referring to fig. 11 and 21, in the flattened (unfolded) state, the first pressing protrusions 4331 of the first pressing member 424 are respectively inserted into the first pressed recesses 4312 of the connecting piece 421, and the second pressing protrusions 4341 of the second pressing member 425 are respectively inserted into the second pressed recesses 4322 of the connecting piece 421. And the first elastic member 422 and the second elastic member 423 provide an elastic restoring force to the connection piece 421. When the external force overcomes the elastic restoring force, the first bracket unit 33 (see fig. 16) can be driven to pivot toward the second bracket unit 35 (see fig. 16), and during the pivoting process, referring to fig. 11 and fig. 22, the first outer pivoting bracket 332 (see fig. 7) will link the first shaft rod 312 to rotate, so as to rotate the first pressing member 424, and by way of example, a first pressing protrusion 4331 and an adjacent first pressed recess 4312, a flattened state in which the first pressing left guide inclined surface 4334 of the first pressing protrusion 4331 abuts against the first pressed right guide inclined surface 4315 of the first pressed protrusion 4311 is converted into a rotated state (i.e., a pair of protrusions) in which the first pressing guide plane 4333 of the first pressing protrusion 4331 abuts against the first pressed guide plane 4313 of the first pressed protrusion 4311, then, the first substrate unit 22 continues to rotate, and the rotation state (i.e., convex-to-convex, concave-to-concave) where the first pressing guide plane 4333 of the first pressing protrusion 4331 abuts against the first pressing guide plane 4313 of the first pressing protrusion 4311 is converted into the folded state where the first pressing right guide inclined plane 4335 of the first pressing protrusion 4331 abuts against the first pressing left guide inclined plane 4314 of the first pressing protrusion 4311. The operation of the second pressing member 425 and the second pressing structure 432 of the connecting plate 421 is the same as the operation of the first pressing member 424 and the first pressing structure 431 of the connecting plate 421, and therefore, the description thereof is omitted.

Referring to fig. 11, it should be particularly noted that when the first pressing guide plane 4333 of the first pressing protrusion 4331 enters the first pressed left guide inclined plane 4314 or the first pressed right guide inclined plane 4315 from the first pressed guide plane 4313, both the first pressed left guide inclined plane 4314 or the first pressed right guide inclined plane 4315 can enter the corresponding first pressed concave part 4312 by being rapidly guided by the first pressed left guide inclined plane 4314 or the first pressed right guide inclined plane 4315, that is, the first substrate unit 22 can automatically rotate to the flat (unfolded) state or the folded (folded) state once passing through a predetermined angle in the rotation process. Thereby increasing the convenience of use for the user. The second substrate unit 23 also has the same function as the first substrate unit 22 that can automatically rotate to the flat state or the folded state through a predetermined angle, and thus the description thereof is omitted.
