2527 and 2577, the second link 267 slides along the corresponding second sliding guide slot 2578, the second link 267 slidably pushes the positioning piece 2586 to rotate, so that the positioning piece 2586 is separated from the first positioning surface 2579, the end of the second link 267 is gradually separated from the opposite side surface of the sliding plate 258 until the end of the second link is abutted to the opposite side surface of the positioning folding device 24, so that the folding device 24 is in a bending state, and the bendable region 31 of the flexible member 30 bends along with the folding device 24 until the back surfaces of the first frame 21 and the second frame 23 are abutted to each other. When the folding device 24 is unfolded again, the ends of the second link members 267 gradually move away from the sides of the sliding plate 258 to separate from each other, and the sides of the positioning pieces 2586 gradually move toward the first positioning surfaces 2579 from a state of being separated from the first positioning surfaces 2579 until the sides abut against each other. Since the side surface of the positioning piece 2586 abuts against the first positioning surface 2579 in the unfolded state and the end of the second link 267 abuts against the side surface of the sliding plate 258 in the bent state, the second frame 23 is limited in the unfolded state and the bent state, and the collapse caused by side impact (such as falling) is reduced or avoided. Of course, in other embodiments, the second frame 23 may be limited only in the bent state or the unfolded state, and the corresponding structure may also be simplified.

Optionally, during the bending process, the mounting frame 254 slides relative to the bendable hinge, and the second frame 23 slides relative to the bendable hinge. Alternatively, the mounting frame 254 slides in the direction of the first frame 21 or the direction of the bendable hinge relative to the bendable hinge, and the second frame 23 slides in the direction of the first frame 21 or the direction of the bendable hinge relative to the bendable hinge. Optionally, the sliding distance of the second frame 23 relative to the bendable hinge is greater than the sliding distance of the mounting frame 254 relative to the bendable hinge. Optionally, the second frame body slides relative to the bendable hinge near the hinge unit of the second frame body. The mounting frame slides relative to the bendable hinge close to the hinge joint unit of the mounting frame. Optionally, the second frame body slides relative to the connecting piece of the bendable hinge. The mounting frame slides relative to the connecting piece of the bendable hinge. Optionally, the sliding distance of the second frame body relative to the connecting piece of the bendable hinge is greater than the sliding distance of the mounting frame relative to the connecting piece of the bendable hinge. During the flattening process, the mounting frame 254 slides relative to the bendable hinge, and the second frame 23 slides relative to the bendable hinge. Alternatively, the mounting frame 254 slides in a direction away from the first frame 21 or a direction of the bendable hinge relative to the bendable hinge, and the second frame 23 slides in a direction away from the first frame 21 or a direction of the bendable hinge relative to the bendable hinge. Optionally, the sliding distance of the second frame 23 relative to the bendable hinge is greater than the sliding distance of the mounting frame 254 relative to the bendable hinge. Optionally, the second frame body slides relative to the bendable hinge near the hinge unit of the second frame body. The mounting frame slides relative to the bendable hinge close to the hinge joint unit of the mounting frame. Optionally, the second frame body slides relative to the connecting piece of the bendable hinge. The mounting frame slides relative to the connecting piece of the bendable hinge. Optionally, the sliding distance of the second frame body relative to the connecting piece of the bendable hinge is greater than the sliding distance of the mounting frame relative to the connecting piece of the bendable hinge.

Optionally, the second frame 23 and the mounting frame 254 are slidably connected in parallel to the bendable hinge. That is, the sliding of the second housing 23 with respect to the flexible hinge is not dependent on the mounting frame 254, and the sliding of the mounting frame 254 with respect to the flexible hinge is not dependent on the second housing 23. Alternatively, the second frame 23 and the mounting frame 254 are slidably coupled to the bendable hinge by respective elastic members 2563.

At this time, the folding device 24 is bent, and the flexible member 30 is bent along with the folding device 24, so that the upper surfaces of the connecting hinge 252, the supporting hinge 251, the middle hinge 250 and the compensating mechanism 253 are connected to each other to form an arc-shaped surface, so as to be convenient for attaching to the supporting member 50. In the process of bending the electronic device 100, the first elastic member 2560 is further compressed to push against the abutting piece 2542 of the mounting frame 254, and the second elastic member 2570 is further compressed to push against the second frame 23, so that the flexible member 30 is always in a tense state, and the flexible member 30 is prevented from being arched and damaged; in addition, the connection member 255 is slidable with respect to the second frame 23, and the attachment frame 254 is slidable with respect to the connection member 255.

When the electronic device 100 needs to be unfolded, the first frame 21 and the second frame 23 are pulled outward, and the connecting hinge 252 connected to the first frame 21 and the compensating mechanism 253 on the second frame 23 are rotated in a direction away from each other. Specifically, the first frame 21 and the second frame 23 of the electronic device 100 are pulled outward to rotate the connecting hinge 252 connected to the first frame 21 and the compensating mechanism 253 connected to the second frame 23 in a direction away from each other, wherein the two protrusions 2511 of one supporting hinge 251 are slidably disengaged from the two insertion holes 2523 of the connecting hinge 252, and the two extending blocks 2525 of the connecting hinge 252 are slidably disengaged from the clearance holes 25110 of one supporting hinge 251, the one supporting hinge 251 is rotated toward one side of the flexible member 30 relative to the middle hinge 250, and the sliding guide pieces 2516 of the supporting hinge 251 are slid outward in the corresponding guide slots 2687; the two protrusions 2511 of the other support hinge 251 are slidingly disengaged from the two insertion holes of the compensation mechanism 253, and the two extension blocks 2569 of the compensation mechanism 253 are slidingly disengaged from the clearance holes 25110 of the other support hinge 251, the other support hinge 251 is rotated toward one side of the flexible member 30 with respect to the middle hinge 250, and the guide sliding pieces 2516 of the support hinges 251 are slid outward corresponding to the guide grooves 2687. Meanwhile, the connecting hinge 252 and the compensating mechanism 253 drive the first link 266 and the second link 267 corresponding to the two rotating mechanisms 26 to rotate toward the flexible member 30, so that the first link 266 slides along the corresponding first guiding

chute

2527 and 2577, the second link 267 slides along the corresponding second guiding chute 2578, the second link 267 slidingly pulls the positioning piece 2586 to rotate so that the positioning piece 2586 rotates to the side surface 2589 to be positioned and attached to the first positioning surface 2579, so as to position the folding device 24 to be in a horizontal state, and the bendable region 31 of the flexible member 30 is unfolded along with the folding device 24. At this time, the anti-folding bar 2665 of each second link 267 abuts against the corresponding connecting bar 613 to prevent the second link 267 from further rotating in the unfolding direction, thereby preventing the flexible member 30 from being damaged by folding.

The first elastic member 2560 and the second elastic member 2570 are compressed when the bendable hinge is unfolded and bent, the compression degree of the first elastic member 2560 when the bendable hinge is unfolded is smaller than that of the first elastic member 2560 when the bendable hinge is unfolded, and the compression degree of the second elastic member 2570 when the bendable hinge is unfolded is smaller than that of the second elastic member 2570 when the bendable hinge is unfolded. When the bendable hinge is bent, the amount of compression of the second elastic member 2570 is greater than that of the first elastic member 2560. When the bendable hinge is bent, the flexible element 30 and the supporting element 50 are fixed relative to each other at the position corresponding to the first frame 21 and slide relative to each other at the position corresponding to the bendable hinge.

The foregoing is illustrative of embodiments of the present invention, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the embodiments of the present invention and are intended to be within the scope of the present invention.
