12 to 14 are top views of the flexible screen 1 device being switched from the flattened state to the double-folded state, respectively, thereby providing a reference position of a cross-section of a cross-sectional view surface in different subsequent states.

Therefore, when a user manipulates the flexible electronic device from the flattened state to the folded state, for example, by manipulating the first casing 221 (see FIG. 1), the first casing 221 and the second casing In a state where the outer shells 231 are flat and adjacent to each other, as shown in FIG. 15 and FIG. 16, when the first outer shell 221 is forced in the up-down direction D2, the first outer shell 221 will support the first inner support. The plate 223, the first outer support plate 224, and the first base 222 apply force to pivot the first bracket unit 33 connected to the first base 222 in the direction of the second bracket unit 35, and at the pivot During the rotation, as shown in FIG. 16 to FIG. 18, the first height difference H1 (see FIG. 9) of the first inner pivot joint end portion 334 and the first outer pivot joint end portion 338 makes the first The inner fixed end 335 causes the first fixed structure 343 to slide in a direction away from the first outer body 337, that is, the first moving structure 344 slides from the end near the base 21 to the first base 222. (See FIG. 15), while driving the first base 222 away from the first base 222 The inner support plate 223 slides in the direction and is separated by a distance d as shown in FIG. 19, that is, the first links 227 of the first inner support plate 223 are moved from the corresponding first through holes 225 from the first The flattened end 2251 slides to the first pair of folded ends 2252. In this case, the first inner support plate 223 moves to the bottom wall near the first casing 221 due to the guidance of the first through holes 225. The distance d can be adjusted correspondingly according to the size of the flexible screen 1, and is not limited to this embodiment.

Referring to FIG. 20, when the first substrate unit 22 is urged upward in the up-down direction D2, the first substrate unit 22 will interlock the first support unit 33 (see FIG. 16) and the first interlocking member 37, Causing the first linking member 37 to link the transmission unit 39 and then the second linking member 38 to link the second linking member 38 to the second bracket unit 35 (see FIG. 16) to drive the second substrate unit 23, Thereby, the second substrate unit 23 is synchronously rotated upward toward the vertical direction D2.

Continuing to refer to FIG. 15 and FIG. 16, when the second substrate unit 23 rotates in the up-down direction D2, the second housing 231 will align the second inner support plate 233, the second outer support plate 234, and the second base. The seat 232 exerts a force to pivot the second bracket unit 35 connected to the second base 232 toward the first bracket unit 33. During the pivoting process, as shown in FIGS. 16 to 18, due to the The second height difference H2 of the second inner pivot end 354 and the second outer pivot end 358 (see FIG. 9) causes the second inner fixed end 355 to interlock the second fixing structure 363 away from the second fixed structure 363. The second outer body 357 slides in the direction, that is, the second moving structure 364 slides from the end near the base 21 to near the second One end of the base 232 simultaneously drives the second base 232 to slide away from the second inner support plate 233 and is separated by the distance d as shown in FIG. 19, that is, the second inner support plate 233 The second link 237 slides from the corresponding second through hole 235 from the second flattened end 2351 to the second folded end 2352. In this case, the second inner support plate 233 due to the second communication The hole 235 is guided to move to the bottom wall near the second casing 231. Thereby, the first substrate unit 22 and the second substrate unit 23 are changed from the flattened state to the folded state, and an avoidance space 25 is formed between the first substrate unit 22 and the second substrate unit 23 as shown in FIG. 19 As shown.

In addition, referring to FIG. 11 and FIG. 21, in the flattened (unfolded) state, the first pressing protrusions 4331 of the first pressing member 424 are respectively inserted into the first pressures of the connecting piece 421. The concave portions 4312 and the second pressing convex portions 4341 of the second pressing member 425 are respectively inserted into the second pressure receiving concave portions 4322 of the connecting piece 421. The first elastic member 422 and the second elastic member 423 provide an elastic restoring force to the connecting piece 421. When external force is applied to overcome 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, refer to 11 and 22, the first outer pivoting bracket 332 (see FIG. 7) will rotate the first shaft 312, thereby rotating the first pressing member 424, and using one of the first pressing protrusions 4331. For example, the first pressure-receiving recess 4312 adjacent to the first pressure-receiving recess 4311 abuts against the first pressure-receiving projection 4311 of the first pressure-receiving convex part 4331. The flattened state of the right guide bevel 4315 under pressure, turn The state of rotation of the first pressure guide plane 4333 replaced by the first pressure protrusion 4331 abuts against the first pressure guide plane 4313 of the first pressure protrusion 4311 (ie, the protrusion is opposed to the recess) ), And then the first substrate unit 22 continues to rotate, and the first pressure guide plane 4333 from the first pressure convex portion 4331 abuts against the first pressure guide of the first pressure convex portion 4311. The rotation state of the guide plane 4313 (that is, convex portion to convex portion, concave portion to concave portion) is converted into the first pressurizing right guide slope 4335 of the first pressurizing convex portion 4331 against the first pressurized convex portion. The folded state of the first compressed left guide slope 4314 of 4311. The operation of the second pressing member 425 and the second pressure receiving structure 432 of the connecting piece 421 is the same as the operation of the first pressing member 424 and the first pressure receiving structure 431 of the connecting piece 421, so it is no longer One by one.

Referring to FIG. 11, it is particularly to be noted that the first pressure guide plane 4333 of the first pressure convex portion 4331 enters the first pressure left guide slope 4314 from the first pressure guide plane 4313 or When the first pressured right guide slope 4315 can be quickly guided by the first pressured left guide slope 4314 or the first pressured right guide slope 4315 and enter the corresponding first receiver. The depressed portion 4312, that is, the first substrate unit 22 can automatically rotate to the flattened (unfolded) state or the double-folded (collapsed) state once it passes a predetermined angle during the rotation process. This increases user convenience. The second substrate unit 23 also has the same effect as the first substrate unit 22 can automatically rotate to the flattened state or the double-folded state through a predetermined angle, so it will not be described again.

In summary, the new flexible electronic device uses the first height difference between the first inner pivot bracket 331 and the first outer pivot bracket 332 of the two pivot mechanisms 3 and the second inner pivot bracket. The second height difference between 351 and the second outer pivot bracket 352 causes the first base 222 and the second base 232 to face away from the first inner support plate 223 and the second inner support plate 233, respectively. Sliding so that the first inner supporting plate 223 and the second inner supporting plate 233 sink relatively and jointly provide an avoidance space 25 for the flexible screen 1 to bend and protrude to avoid the flexible screen 1 Excessively bend or squeeze, thereby reducing the volume of the flexible electronic device to improve the convenience of carrying. Therefore, it can indeed achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
