Sleeving the sleeving assembly 268 on the same end of the first connecting shaft 261 and the second connecting shaft 265, specifically, the two first connecting shafts 261 are respectively inserted into the two positioning through holes 2683 of the first sleeving piece 2681, the inner cavities of the first connecting cylinders 2686 of the two second sleeving pieces 2685 and one of the through holes of the positioning plate 2668, the two first connecting shafts 261 are fixed in the two positioning through holes 2683, and the two second sleeving pieces 2685 are respectively rotatably connected to the two first connecting shafts 261; meanwhile, the two second connecting shafts 265 are respectively inserted into another through hole of the positioning plate 2688 of the two second sleeving pieces 2685, the connecting hole 2675 of the second connecting rod piece 267 and the inner cavity of the second connecting cylinder 2687, so that the two second connecting rod pieces 267 are respectively and fixedly sleeved on the two second connecting shafts 265, and the two second sleeving pieces 2685 are respectively and rotatably connected to the two second connecting shafts 26.
When the linkage mechanism 26 is bent, the first link member 266 and the second link member 267 on one of the second connecting shafts 265 rotate toward the other first link member 266, because the first link member 266 and the second link member 267 are fixedly connected to the corresponding second connecting shaft 265, the fixing member 2621 is fixedly connected to the first connecting shaft 261, and each of the first connecting shaft 261 and each of the second connecting shaft 265 are rotatably connected to the corresponding transmission member 2641, the second gear 2665 of the first link member 266 on one of the second connecting shafts 265 rotates along the corresponding first gear 2623, and the first link member 266 drives the third gear 2645 of the corresponding transmission member 2641 to rotate along the third gear 2645 of the corresponding other transmission member 2641 through one of the second connecting shafts 265. Optionally, the first connecting shaft 261 and the second connecting shaft 265 rotate in the shaft hole 2643 of the corresponding transmission piece 2641. The rotation of the transmission member 2641 drives another transmission member 2641 engaged therewith to rotate, the another transmission member 2641 drives another second connecting shaft 265 to rotate, and the another second connecting shaft 265 drives the second gear 2665 of the another first connecting rod 266 to rotate along the first gear 2623 corresponding to the fixing block 2621 and drives the another first connecting rod 266 and the second connecting rod 267 to rotate, so that the two first connecting rods 266 and the two second connecting rod 267 approach each other and are bent at the same time. The first link 266 and the second link 267 on the left and right sides can rotate synchronously under the driving of the linkage 26. In this linkage process, each of the first connecting shaft 261 and the second connecting shaft 265 is interference-fitted with the corresponding damping hole 2693 of the damping member 269, so that the damping member 269 can rotationally position the two first link members 266 at any angle.
In other usage manners, the two first connecting rods 266 and the two second connecting rods 267 can rotate together in opposite directions, because the first connecting rods 266 and the second connecting rods 267 are fixedly connected with the second connecting shafts 265, the fixing member 2621 is fixedly connected with the first connecting shafts 261, and each first connecting shaft 261 and each second connecting shaft 265 are rotatably connected with the corresponding transmission member 2641; therefore, the second gears 2665 of the two first link members 266 rotate along the corresponding first gears 2623; the two first link members 266 and the two second link members 267 drive the third gears 2645 of the two transmission members 2641 of the same second gear assembly 264 to rotate together through the corresponding second connecting shafts 265, so that the two transmission members 2641 approach each other, and the two first link members 266 and the two second link members 267 of each first gear assembly 262 approach each other at the same time to be bent.
When the linkage mechanism 26 is unfolded from the bent state, one of the first connecting rod 266 and the second connecting rod 267 at the same side is rotated toward the first connecting rod 261 far away from the other side, because the first connecting rod 266 and the second connecting rod 267 are fixedly connected with the corresponding second connecting shaft 265, the fixing member 2621 is fixedly connected with the first connecting shaft 261, and each of the first connecting shaft 261 and each of the second connecting shaft 265 are rotatably connected with the corresponding transmission member 2641; therefore, the second gear 2665 of one of the first link members 266 rotates along the corresponding first gear 2623, and the one of the first link members 266 drives the third gear 2645 of the corresponding transmission member 2641 to rotate along the third gear 2645 of the corresponding other transmission member 2641 through the corresponding second connecting shaft 265. Optionally, the first connecting shaft 261 and the second connecting shaft 265 rotate in the shaft hole 2643 of the corresponding transmission piece 2641. The rotation of the transmission member 2641 drives another transmission member 2641 engaged therewith to rotate, the another transmission member 2641 drives another second connecting shaft 265 to rotate, and the another second connecting shaft 265 drives the second gear 2665 of the another first connecting rod 266 to rotate along the first gear 2623 corresponding to the fixing block 2621 and drives the another first connecting rod 266 and the another second connecting rod 267 to rotate until the second stopping surface 2667 of each first connecting rod 266 abuts against the first stopping surface 2624, so that the two first connecting rods 266 and the two second connecting rod 267 are simultaneously away from each other and are bent. In this linkage process, each of the first connecting shaft 261 and the second connecting shaft 265 is interference-fitted with the corresponding damping hole 2693 of the damping member 269, so that the damping member 269 can rotationally position the two first link members 266 at any angle.
In other usage manners, the two first connecting rods 266 and the two second connecting rods 267 can rotate together in opposite directions, because the first connecting rods 266 and the second connecting rods 267 are fixedly connected with the corresponding second connecting shafts 265, the fixing member 2621 is fixedly connected with the first connecting shafts 261, and each first connecting shaft 261 and each second connecting shaft 265 are rotatably connected with the corresponding transmission member 2641; therefore, the second connecting shafts 265 fixed to the two first link members 266 drive the second gears 2665 of the first link members 266 to rotate in opposite directions along the corresponding first gears 2623; meanwhile, the two second link members 267 also drive the second gear 2665 of the corresponding first link member 266 to rotate in the opposite direction along the corresponding first gear 2623 through the corresponding second connecting shaft 265, and the second connecting shaft 265 drives the third gear 2645 of the corresponding transmission member 2641 to rotate in the opposite direction along the third gear 2645 of the corresponding other transmission member 2641, so that the two first link members 266 and the two second link members 267 are simultaneously away from each other and are flattened.
Alternatively, in some embodiments, the second link 267 can be omitted and only the first link 266 can be retained without affecting the linkage process of the linkage mechanism. Further, the first link 266 may only have one first rod 2661 and one connecting post 2663, and the other first rod 2661 and one connecting post 2663 may be omitted, so that the linkage of the linkage mechanism may still be linked normally.
Referring to fig. 7 to 10, when the first connecting hinge 254 is assembled, the connecting rod 2514 of the positioning element 2511 is inserted into the elastic element 2515 and then installed in the installation groove 2560 of the installation frame 256, so that the fixture block 2512 of each positioning element 2511 is inserted into the notch 25601 and extends into the corresponding first sliding guide groove 2567; the two slide plates 252 are respectively inserted into the two slide grooves 2566 of the mounting frame 256; the connecting frame 257 is covered on the mounting frame 256, so that the two connecting posts 2576 of the connecting frame 257 can be slidably inserted into the two strip-shaped holes 2564 of the mounting frame 256, the two abutting pieces 2575 of the connecting frame 257 abut against the first elastic pieces 2563 on the mounting frame 256, the two connecting pieces 2573 of the connecting frame 257 are covered on the two sliding plates 252, and the plurality of locking pieces are inserted into the connecting holes 2574 of the connecting pieces 2573 and locked to the corresponding sliding plates 252. The locking member is slidable within the connection hole 2576 such that the sliding plate 252 is slidable relative to the connection frame 257. The two locking members are inserted into the strip-shaped holes 2564 of the mounting frame 256 and connected to the corresponding connecting holes 2577. At this time, the first elastic member 2563 is elastically clamped between the corresponding abutting piece 2575 and the mounting frame 256, and each connecting column 2576 can slide along the corresponding strip-shaped hole 2564, that is, the connecting frame 257 can slide along the strip-shaped hole 2564 relative to the mounting frame 256; the two slide plates 252 can slide in the two slide slots 2566, i.e., the two slide plates 252 can slide relative to the mounting frame 256.
Referring to fig. 3 to fig. 26, when assembling the folding device 24, the middle hinge assembly 250 is assembled, specifically, two second middle hinges 2505 are respectively placed on two opposite sides of the first middle hinge 2501, and two protrusions 2506 on the same side of each second middle hinge 2505 are respectively inserted into two notches 2502 on the same side of the first middle hinge 2501, so that the shaft holes 2507 of the protrusions 2506 on the same side correspond to the corresponding clipping holes 2503. The two support hinges 253 are respectively arranged at two opposite sides of the middle hinge assembly 250, so that the convex block 2531 at the middle part of each support hinge 253 is respectively inserted into the gap of the corresponding second middle hinge 2505; placing the two link mechanisms 26 at two opposite ends of the middle hinge assembly 250, respectively, so that each first connecting shaft 261 of one end of each link mechanism 26 away from the socket assembly 268 is inserted into the corresponding clamping hole 2503 and shaft hole 2507 of the first middle hinge 2501, so that the two second connecting shafts 265 are inserted into the through holes 2532 of the two support hinges 253 and the corresponding shaft holes 2508 of the two second middle hinges 2505, respectively, and the protrusions 2531 at two opposite ends of the two support hinges 253 are inserted into the connecting grooves between the two second connecting cylinders 2687 of the two second socket pieces 2685 at the same side of the two socket assemblies 268 and are sleeved on the corresponding second connecting shafts 265; the first link 266 and the second link 267 at both sides of each linkage 26 are respectively inserted into the first slide guide groove 2534 and the second slide guide groove 2535 of the corresponding support hinge 253; the first connecting hinge 254 and the second connecting hinge 258 are respectively arranged at two sides of the two supporting hinges 253 far away from the middle hinge assembly 250, so that the first connecting rod 266 and the second connecting rod 267 at one side of each linkage mechanism 26 are inserted into the first guide chute 2567 and the second guide chute 2568 of the first connecting hinge 254, and the clamping block 2512 of each positioning piece 2511 on the first connecting hinge 254 is clamped into the first bayonet 2668 of the corresponding first connecting rod 266; the switching shaft 2674 of the second link member 267 inserted into each second guiding chute 2568 is connected to the corresponding sliding plate 252 through a positioning piece 60, specifically, the positioning piece 60 is a rectangular piece, two opposite end faces of the positioning piece 60 are arc-shaped, one end of the positioning piece 60 is provided with a rotating hole, the other end of the positioning piece 60 is provided with a strip-shaped hole, the switching shaft 2674 of the second link member 267 rotates and slidably connects to the strip-shaped hole of the positioning piece 60, and the rotating hole of the positioning piece 60 is rotatably connected to the connecting hole 2524 of the sliding plate 252 through a locking piece. Thus, the positioning plate 60 can slide and rotate relative to the second link 267 and can rotate relative to the sliding plate 252. Alternatively, the adapting shaft 2674 of the second link 267 can also be rotatably connected to the rotating hole of the positioning piece 60, and the strip-shaped hole of the positioning piece 60 is slidably and rotatably connected to the connecting hole 2524 of the sliding plate 252 through the locking piece. Thus, the positioning plate 60 can rotate relative to the second link 267 and can rotate and slide relative to the sliding plate 252. The support hinge 253 adjacent to the first connecting hinge 254 forms an inclined stopper surface 2539 at a position corresponding to the positioning piece 60 in the second guide groove 2568. The positioning plate 60 can be abutted against the position-limiting surface 2539 or separated from the position-limiting surface 2539. Alternatively, the second link member 267 can slide relative to the first connecting hinge 254, the second connecting hinge 258 and the support hinge 253 when the folding device 24 is folded. Optionally, when the folding device 24 is bent, the side surface of the positioning piece 60 is separated from the limiting surface 2539, and the end of the second link member 267 abuts against the sliding plate 252, so as to limit the sliding plate 252 in the length direction of the sliding chute. When the folding device 24 is unfolded, the side surface of the positioning piece 60 abuts against the limiting surface 2539, the end of the second link member 267 is separated from the sliding plate 252, and the sliding plate 252 is also limited in the length direction of the sliding groove. In this way, the sliding plate 252 can be prevented from collapsing in the sliding groove when falling, so that the flexible screen fixedly connected with the sliding plate 252 cannot be arched and damaged. The first link 266 and the second link 267 on the other side of each linkage 26 are inserted into the first guide slot 2580 and the second guide slot 2582 of the second connecting hinge 258, and the locking block 2512 of each positioning element 2511 on the second connecting hinge 258 is locked into the corresponding first locking opening 2668 of the first link 266. At this time, the folding device 24 is in the unfolded state. Alternatively, the folding device 24 includes a first slider connected to the shutter units, and the first slider is slidable with respect to the hinge assembly 25 when the shutter units are relatively rotated; in the present embodiment, the first sliding member is the mounting frame 256, that is, when the middle stopper 270, the connecting stopper assembly 271 and the fixed stopper 275 rotate relatively, the mounting frame 256 slides relative to the hinge assembly 25. Alternatively, when each shielding unit rotates relatively, the first sliding member is driven by the corresponding shielding unit to slide toward the hinge assembly 25 relative to the hinge assembly 25, i.e., when the middle shielding plate 270, the connecting shielding plate assembly 271 and the fixed shielding plate 275 rotate relatively, the mounting frame 256 is driven by the corresponding shielding unit to slide toward the hinge assembly 25 relative to the hinge assembly 25. Optionally, each hinge comprises a support hinge 253 on the outside, through which a link member is inserted in the first slider; in this embodiment, each hinge includes a support hinge 253 at the outer side, and a first link 266 and a second link 267 are inserted into the mounting frame 256 through the support hinge 253.
Two shielding mechanisms 27 are respectively disposed at two opposite ends of the hinge assembly 25, such that the connecting portion 2701 of the middle blocking piece 270 of each shielding mechanism 27 is fixedly connected to the end of the first sleeve 2681, the two connecting portions 2751 of the two fixing blocking pieces 275 are respectively fixedly connected to the ends of the first connecting hinge 254 and the second connecting hinge 258, the connecting blocking piece assembly 271 of the shielding mechanism is separated from the sleeve assembly 268 and the supporting hinge 253, and the fixing blocking pieces 275 are separated from the supporting hinge 253. The shutter mechanism 27 is bent as the hinge assembly 250 is bent. At this time, the first and second connecting hinges 254 and 258 are connected to the sides of the two support hinges 253 away from the intermediate hinge assembly 250 by the first and second link members 266 and 267; the two support hinges 253 are rotatably connected to two second middle hinges 2505 of the middle hinge assembly 250 by two second connecting shafts 265, respectively; the two second middle hinges 2505 are rotatably connected to opposite sides of the first middle hinge 2501 by two first connecting shafts 265, respectively. When the assembled folding device 24 is unfolded and flat, the front face of the first central hinge 2501, the front face of the second central hinge 2505, the front face of the support hinge 253, the front face of the first connecting hinge 254 and the front face of the second connecting hinge 258 are in the same plane to facilitate installation of the flexible member 30. Alternatively, the first shielding unit is fixedly connected with the hinge assembly 25, and the second shielding unit is fixedly connected with the first sliding member; in this embodiment, the middle stop 270 is fixedly attached to the hinge assembly 25, and the fixed stop 275 is fixedly attached to the mounting frame 256. Alternatively, each shielding unit covers the side of the hinge assembly 25 between the outer side of the bend and the inner side of the bend.
When the folding device 24 is unfolded, the hinge positions of the hinges together define a first plane, the hinge positions of the shielding units together define a second plane, and the first plane and the second plane are parallel and are different.
Alternatively, each hinge is hinged through a first rotating shaft, each shielding unit is hinged through a second rotating shaft, the axial lines of the first connecting shaft 261 and the second connecting shaft 265 are in a first plane, and the axial lines of the rotating shafts of the shielding mechanism 27 are in a second plane; in this embodiment, the first rotating shaft refers to a first connecting shaft 261 and a second connecting shaft 265, and each hinge is hinged through the first connecting shaft 261 and the second connecting shaft 265; the second rotation axis refers to a rotation axis 2736, and each shielding unit is hinged through the rotation axis 2736. Optionally, the first plane and the second plane are parallel and different. Optionally, the first plane is further away from the flexible screen than the second plane. Alternatively, the hinged position of the middle blocking piece 270 and the first blocking piece 272, the hinged position of the first blocking piece 272 and the second blocking piece 273, and the hinged position of the second blocking piece 273 and the fixed blocking piece 275 of the shielding mechanism 27 are closer to the flexible member than the hinged position of the first nesting member 2681 and the second nesting member 2685 and the hinged position of the second nesting member 2681 and the support hinge 253. Because the distances between the first plane and the second plane are different, when the folding device 24 is bent, the radius of the arc formed by the first connecting shaft 261 and the second connecting shaft 265 originally in the first plane is smaller than the radius of the arc formed by the rotating shaft originally in the first plane, and in order to adapt to the difference in radius, the first connecting hinge 254 and the second connecting hinge 258 fixed to the two fixed blocking pieces 275 can slide relative to the supporting hinge 253, that is, when the folding device 24 is bent, the first connecting hinge 254 and the second connecting hinge 258 can slide relative to the supporting hinge 253. Optionally, the first connecting hinge 254 and the second connecting hinge 258 slide relative to the respective adjacent support hinge 253 toward the respective adjacent support hinge 253 as the folding device 24 is folded. Alternatively, the first and second connecting hinges 254, 258 slide relative to each other and do not rotate relative to the adjacent support hinge 253 when the folding device 24 is folded. Alternatively, as the folding device 24 is folded, the support hinge 253 rotates relative to the adjacent second nesting member 2685, and the second nesting member 2685 rotates relative to the first nesting member 2681.
Because the straight gear is adopted for linkage in a meshing mode, compared with the mode of adopting the bevel gear for linkage in a meshing mode, the method does not need high manufacturing precision, can effectively reduce the production cost and improve the production efficiency.

The connecting frame 257 and the mounting frame of the first connecting hinge 254 can slide relatively in a direction perpendicular to the bending axis of the intermediate hinge assembly 250; the first elastic member 2563 generates an elastic force that pushes the contact piece 2575 of the connection frame 257 to a side away from the intermediate hinge unit 250, and the second elastic member 2569 generates an elastic force that pushes the first frame body 21 away from the first connection hinge.

Optionally, when the folding device 24 is bent, the supporting sheet 50 may drive the connecting sheet 2571 to slide relative to the second frame 23, and the flexible screen may drive the first frame 21 to slide relative to the second frame 23.

The bendable region 31 of the flexible member 30 can bend along with the bending of the folding device 24, and the first elastic member 2563 pushes the abutting sheet 2575 outwards to drive the connecting plate 2571 to push the supporting sheet to a side away from the middle hinge assembly 250, so that the supporting sheet is in a tight state. The second elastic piece outwards supports and pushes the first frame body, so that the flexible screen is tightened, and the flexible screen is prevented from being arched and damaged. When the flexible element 30 is in the flattened state, the detent 2512 of each detent 2511 snaps into the corresponding first bayonet 2668 to position the hinge assembly 25 to maintain the flattened state. Optionally, the hinge assembly 25 further includes a link member connected to the first rotating shaft, the link member being inserted into the first sliding member and being slidable relative to the first sliding member; in this embodiment, the link member is a first rod 2661 and/or a connecting rod 2671, the first sliding member is the mounting frame 256, and during the bending or flattening process of the folding device 24, the first rod 2661 and the connecting rod 2671 are respectively inserted into the corresponding first sliding guide slot 2567 and the corresponding second sliding guide slot 2568 and can slide relative to the mounting frame 256.
