Wherein, the two elastic members 123 are disposed such that the outer connector 122 and the inner connector 121 can be relatively moved while being maintained on a predetermined trajectory. For example, when the pivot module 11 is in the flattened position, each of the elastic members 123 can restrict the movement of the outer member 122 away from the plurality of pivots 111, thereby avoiding the soft display screen 5 (or the carrier board 4). Inside fold.

In more detail, the outer connector 121 is provided for a cover plate (not shown), thereby shielding the two supporting devices 1, the connecting member 2 and the connecting tube 3 through the covering plate to avoid the above two supports. The device 1, the connector 2, and the connecting tube 3 are injured to the user. The inner connecting member 121 has a plate body 1211, two flanges 1212 extending from the end edges of the plate body 1211 toward the carrying plate 4 (or the outer connecting member 122), and at least one fixing formed on the plate body 1211. A portion 1213 (eg, an opening), and at least one guide pin 1214 and two inner connecting portions 1215 disposed on the plate body 1211.

The outer connector 122 has a connecting plate 1221 , a plurality of guiding wheels 1222 attached to the two ends of the connecting plate 1221 , and two outer connecting portions 1223 disposed on the connecting plate 1221 . The outer connector 122 is fixed to the carrier plate 4 through the connecting plate 1221, and the connecting plate 1221 is formed with an elongated at least one track hole 1224, and the guiding pin 1214 of the inner connecting member 121 is inserted in the The track holes 1224 are relatively movable. The two flanges 1212 of the inner connector 121 are slidably mounted to the plurality of guide wheels 1222 of the outer connector 122, respectively.

However, in the embodiment, the two flanges 1212 are respectively mounted on the plurality of guide wheels 1222. However, in an embodiment not shown, the inner connector 121 is also Only one flange 1212 may be formed, and the outer member 122 forms at least one guide wheel 1222 corresponding to the flange 1212.

Thereby, when the flexible display device 100 is bent to synchronize the pivot modules 11 of the two supporting devices 1 from the flattened position to the outwardly folded position (as shown in FIGS. 8 and 9 ), The carrier board 4 (or the flexible display screen 5) is bent, so that the outer connector 122 in each buffer module 12 slides relative to the inner connector 121 toward the adjacent pivot 111 (as shown in FIG. 9 with respect to FIG. 4). And the elastic member 123 is compressed to store a restoring force.

Further, each of the elastic members 123 is a torsion spring in the embodiment, and one ends of the two elastic members 123 are respectively mounted on the two inner connecting portions 1215 of the inner connecting member 121, and the The other ends of the two elastic members 123 are respectively mounted to the two outer connecting portions 1223 of the outer member 122. Wherein, when the pivot module 11 is in the flattened position, the two elastic members 123 are in an original state without being pressed or stretched, so that the two elastic members 123 can maintain the inner connector 121 and The relative position of the outer member 122; when the pivot module 11 is in the outer folding position, the two elastic members 123 are pressed to store the restoring force, and the restoring force tends to make each elastic member 123 Reverting to the original state, thereby facilitating the pivot module 11 to move from the outer folded position toward the flattened position.

Furthermore, as shown in FIG. 4, when the guide pin 1214 is relatively moved to one of the two ends of the track hole 1224 (such as the inner end of the track hole 1224 in FIG. 4), the guide pin 1214 and the track hole 1224. The inner joint member 121 is prevented from moving further away from the pivot member 111 with respect to the outer member 122, so that the hinge module 11 is maintained in the flattened position. As shown in FIG. 9, when the guide pin 1214 is relatively moved to the other end of the track hole 1224, the other end (such as the outer end of the track hole 1224 in FIG. 9), the guide pin 1214 and the track hole 1224 are restrained. Therefore, the inner joint member 121 cannot be further moved toward the pivot shaft 111 with respect to the outer joint member 122, so the hinge module 11 is maintained at the inner folded position.

1 and 3, the connecting member 2 is an elongated piece, and each connecting member 2 is a two outer connecting member 122 that is fixedly adjacent but belongs to different supporting devices 1 (such as the upper left side in FIG. 1). The outer connector 122 and the lower left outer connector 122), one ends of the plurality of connecting tubes 3 (such as the top end in FIG. 1 ) are respectively sleeved on the plurality of pivots 111 of one of the supporting devices 1 , the plurality of connecting tubes The other end of 3 (the bottom end in Fig. 1) is respectively sleeved to a plurality of pivots 111 of the other supporting device 1. Thereby, by providing the above-described connecting member 2 and the connecting pipe 3, it is possible to assist the two supporting devices 1 to operate more smoothly.

As shown in FIGS. 1 and 3, the carrier plate 4 is connected to the outer connector 122 of the two supporting devices 1 (the connecting plate 1221). The carrier board 4 includes a metal layer 41 and a cushion layer 42. The metal layer 41 is fixed to the connecting board 122 of the two supporting devices 1 and is mounted with the soft display. The screen 5 is sandwiched between the metal layer 41 and the two support devices 1.

In addition, although the present embodiment is described as an example in which the flexible display panel 5 is attached to the carrier board 4, it is not limited thereto. For example, in another embodiment not shown, the flexible display screen 5 also has a connecting plate 1221 that can be directly fixed to the outer members of the two supporting devices 1.

According to the above, the flexible display device 100 disclosed in the present embodiment can be moved relative to the inner connector 121 by the external member 122 when the pivot module 11 is bent between the flattened position and the folded position. The hub module 11 is prevented from being stretched on the soft display screen 5 (or the carrier board 4). Therefore, the appearance of the flexible display screen 5 can be consistent with the hinge module 11 so that the flexible display screen 5 can be effectively supported by the two supporting devices 1 described above.

Furthermore, the flexible display device 100 is designed such that the hub module 11 of each support device 1 is difficult to face from the flattened position. The direction of the non-outer folding position is actuated to avoid damage caused by the fold of the flexible display screen 5 (or the carrier board 4).

[Embodiment 2]

Referring to FIG. 10 to FIG. 12 , the second embodiment of the present invention is similar to the above embodiment, and the same portions are not described again, and the main difference between the two embodiments is the supporting device 1 . In the buffer module 12 of the embodiment, the number of the elastic members 123 is one, and each of the buffer modules 12 further includes a connection between the inner connector 121 and the outer connector 122 and is linked to the adjacent pivot. A locking unit 124 of the shaft 111. Furthermore, the outermost two pivot shafts 111 of the pivot shaft 111 of the embodiment are respectively formed with a linking portion 1111 at substantially the center thereof, and each of the linking portions 1111 is a helical gear in the embodiment. But it is not limited to this.

Further, the locking unit 124 includes a connecting rod 1241 and a limiting member 1242. The connecting rod 1241 is pivotally disposed on the connecting member 121 and interlocked with the linking portion 1111 of the adjacent pivot 111. One end of the connecting rod 1241 is engaged with the linking portion 1111 of the adjacent pivot shaft 111, so that the connecting rod 1241 can be driven by the linking portion 1111 of the pivot shaft 111 to rotate relative to the inner connecting member 121. In addition, the limiting member 1242 is a tension spring in the embodiment, and the limiting member 1242 has a first end 1243 and a second end 1244 at opposite ends, and the first of the limiting members 1242 The end 1243 and the second end 1244 are respectively fixed to the connecting rod 1241 and the outer connecting member 122.

Therefore, when the pivot module 11 is moved from the flattened position (as shown in FIG. 10) toward the outer folded position (not shown), the second end 1244 of the limiting member 1242 is driven by the connecting member 122 toward the connecting rod 1241. When the direction is moved, the connecting rod 1241 rotates relative to the inner connecting member 121 to rotate the first end 1243, thereby causing the limiting member 1242 to bend, but the bending of the limiting member 1242 does not generate enough to affect the movement of the outer connecting member 122. power.

Furthermore, when the hub module 11 is from the flattened position and is intended to face the non-outside fold When the direction of the movement is set (corresponding to the inward bending of the flexible display screen 5), if the outer member 122 moves away from the pivot axis 111, the limiting member 1242 is stretched to generate an elastic force, so that the connecting rod 1241 cannot be opposite. The inner member 121 rotates, so that the interlocking portion 1111 of the pivot shaft 111 cannot rotate. However, the pivot 111 cannot be rotated, which in turn restricts the movement of the outer connector 122 away from the pivot 111. Therefore, when the pivot module 11 is to be moved from the flattened position toward the non-outwardly folded position, the locking unit 124 can cause the outer joint 122 and the pivot shaft 111 having the interlocking portion 1111 to be operationally restricted from each other, thereby being Locked and does not work. That is to say, when the hinge module 11 is in the flattened position, the locking unit 124 causes the adjacent pivots 111 to move only in the direction of the outer folded position.

Thereby, the outer connector 122 and the inner connector 121 can be relatively moved while being maintained on a predetermined trajectory by the cooperation of the locking unit 124 with other components. For example, when the pivot module 11 is in the flattened position, the locking unit 124 enables the adjacent pivots 111 to move only in the direction of the outer folded position, thereby avoiding the soft display screen 5 (or the carrying board 4). Internal folds cause damage.

The above description is only the preferred and feasible embodiment of the present invention, and is not intended to limit the scope of protection of the present invention. Any changes and modifications made by the scope of the present application should be protected by the present invention.
