Please refer to FIG. 46 , which provides a second embodiment. The limiting member 34 is provided with a limiting groove 345 extending toward the first end 341 at the second end 342 , and the limiting groove 345 is slidably connected to the connection. The connecting piece 32 is used to limit the connecting piece 32 to approach or move away from the flexible board 31 within a predetermined distance.

The connecting module 30 includes two limiting members 34, and the two limiting members 34 are respectively fixed at both ends of the first rotating shaft 329 in the longitudinal direction. The limiting member 34 is a package, and the limiting member 34 can also cover and encapsulate both ends of the connecting member 32 . In one embodiment, the limiting member 34 is a flexible bending member. The first end 341 is fixedly connected to the connecting side 313 of the flexible board 31 by means of bonding or snapping, and is bent or unfolded together with the connecting side 313 . The first end 341 has a plurality of protrusions 346 extending toward the second end 342, the plurality of protrusions 346 are arranged along the length direction of the connecting side 313, and the plurality of protrusions 346 are aligned with the connecting member 32. Both ends of the connection module 30 are covered to improve the appearance and structural performance of the connecting module 30. Each of the protrusions 346 has two inclined sidewalls 347 that are inclined to form an included angle. The inclined sidewalls 347 of two adjacent protrusions 346 are arranged at an included angle. When the restricting member 34 is deployed with the flexible board 31 , there is a gap between the inclined side walls 347 of two adjacent protrusions 346 . When the restricting member 34 bends with the flexible plate 31, the inclined side walls 347 of two adjacent protrusions 346 move closer to each other, and finally a plurality of the protrusions 346 shrink together to form a joint on the The ends of the connection piece 32 are covered.

Both ends of the first rotating shaft 329 are slidably connected to the limiting slot 345 along the length direction of the limiting slot 345 . The limiting groove 345 limits the offset of the first rotating shaft 329 relative to the center of the flexible plate 31 , so as to limit the offset of the connecting member 32 relative to the flexible plate 31 . Since the distance between the first rotating shaft 329 and the flexible board 31 increases when the first housing 10 is against the second housing 20 by more than 180°, the end of the first rotating shaft 329 One end of the limiting slot 345 slides toward the other end.

When the first rotating shaft 329 slides from one end of the limiting slot 345 to the other end, the first rotating shaft 329 cannot continue to slide, and the flexible board 31 cannot continue to move away from the first rotating shaft 329 . The first casing 10 cannot continue to increase the turning angle relative to the second casing 20, that is, it is ensured that the first casing 10 and the second casing 20 turn over each other within a safe angle range, which ensures The flexible display screen 40 is bent within a safe angle range, which prevents the flexible display screen 40 (see FIG. 1 ) from being bent.
