Fig. 2 is a schematic view of the folding module shown in fig. 1 after being folded. Fig. 3 is a schematic partial cross-sectional view taken along a-a in fig. 1. The application provides a folding module 1, folding module 1 includes a plurality of hinge structures 10 that set up at intervals, every hinge structure 10 includes a plurality of articulated link assembly 20 in order, every link assembly 20 includes pivot 21, pivot 21 has an axis (the dotted line that letter O represented in the figure), the axis is parallel to the direction of arrangement (the direction that D1 represented in the figure) of a plurality of hinge structures 10.

The application provides a folding module 1 is used for buckling and folding, when flexible screen 3 or other structures were installed on folding module 1, alright make flexible screen 3 or other structures buckle through folding module 1. Moreover, the folding module 1 provided by the present application can be applied not only to the field of electronic products, but also to other fields such as watches. The present embodiment is schematically described only in the field of electronic products.

The folding module 1 provided by the present application comprises a plurality of spaced hinge structures 10. Wherein bending of the flexible screen 3 mounted thereon at a plurality of locations to form a curved screen is achieved by means of the hinge structure 10. The difficulty of realizing the bent screen can be further reduced by the hinge structures 10, and the stress concentration problem of the flexible screen 3 during the curling process can be reduced by arranging the hinge structures 10 at intervals, so that the flexible screen 3 is uniformly bent and curled. The present embodiment is illustrated with the number of hinge structures 10 being 2.

The present application provides a hinge structure 10 comprising a plurality of link assemblies 20 that are articulated in sequence. Where the link assembly 20 is the basic unit in the hinge structure 10, it is also understood that the hinge structure 10 is made up of a plurality of link assemblies 20. And the plurality of link assemblies 20 are sequentially articulated together, i.e., each link assembly 20 is movable, e.g., detachable, movable, rotatable, etc., relative to an adjacent link assembly 20 to effect bending of the hinge structure 10. Specifically, each link assembly 20 includes a rotating shaft 21, i.e., each link assembly 20 is movable relative to the rotating shaft 21 of an adjacent link assembly 20, and each rotating shaft 21 has an axis, which can be understood as a rotation center of the rotating shaft 21. Since each hinge structure 10 includes a plurality of link assemblies 20, each hinge structure 10 includes a plurality of rotation shafts 21, and the plurality of rotation shafts 21 can provide a plurality of rotation centers for the folding module 1, so that the folding module 1 can be bent at a plurality of places.

In the related art, although the folding module 1 is also included in the folding screen electronic device 4, the folding module 1 also includes a plurality of hinge structures 10, and each hinge structure 10 also includes a plurality of rotating shafts 21, in the folding screen electronic device 4, only a partial region of the flexible screen 3 needs to be bent to form the flexible screen 3, so that the partial region of the flexible screen 3 can be bent by making the direction of the axis of the rotating shaft 21 perpendicular to the arrangement direction of the plurality of hinge structures 10.

It can also be understood that the arrangement direction of the plurality of rotation shafts 21 is perpendicular to the arrangement direction of the plurality of hinge structures 10. Like this when flexible screen 3 installs on folding module 1 and the size covers one side of flexible screen 3, thereby just can make flexible screen 3 many places all can buckle through a plurality of pivots 21 and form crooked screen. In summary, since the present application is different from the related art in terms of technical problems, the present application is for forming a rolled screen later, and the related art is for forming a folded screen, the present application also adopts a technical solution different from the related art.

As can be seen from the above, each link assembly 20 is movable relative to the rotational axis 21 in the adjacent link assembly 20. The present application thus provides a number of implementations. In the present embodiment, a bushing 22 may be provided in the link assembly 20 to be fitted with the rotation shaft 21. Thus for two adjacent link assemblies 20: the nth link assembly 20 and the (N + 1) th link assembly 20, where N is a positive integer. For example, N is 10, i.e., it means that the hinge structure 10 includes 10 link assemblies 20, and two adjacent link assemblies 20, e.g., a first link assembly 20 and a second link assembly 20; a fifth link assembly 20 and a sixth link assembly 20; a ninth link assembly 20 and a tenth link assembly 20. The sleeve 22 of the nth link assembly 20 is sleeved on the rotating shaft 21 of the (N + 1) th link assembly 20, and the nth link assembly 20 can rotate around the rotating shaft 21 of the (N + 1) th link assembly 20. It is also understood that, in the present embodiment, instead of the bushing 22 of each link assembly 20 being sleeved on the rotary shaft 21 for rotation, the bushing 22 of the previous link assembly 20 is sleeved on the rotary shaft 21 of the next link assembly 20 for rotation of the previous link assembly 20 about the next link assembly 20.

Please refer to fig. 5, fig. 5 is a schematic structural diagram of a link assembly according to another embodiment of the present application. In this embodiment, the link assembly 20 includes a first link 30 and a second link 40 connected to each other, the first link 30 includes a base plate 31 and a protruding portion 32 protruding from two opposite sides of the base plate 31, a first through hole 33 is opened on the protruding portion 32, and a part of the rotating shaft 21 is disposed in the first through hole 33. The second link 40 includes a sleeve 22, a second through hole 23 is formed in the sleeve 22, and the rotating shaft 21 is further disposed in the second through hole 23.

This embodiment also allows each link assembly 20 to include a first link 30 and a second link 40, with the first link 30 being used to mount the shaft 21 and the second link 40 being used to include the bushing 22. Specifically, the first link 30 includes a base plate 31 and a protrusion 32, wherein the base plate 31 is used for fixing the protrusion 32, and a mounting carrier for other subsequent structures can be provided. In addition, a first through hole 33 may be opened on the protrusion 32, and a part of the rotating shaft 21 may be disposed in the first through hole 33, so that the protrusion 32 may be used to mount and fix the rotating shaft 21. It will also be understood that the function of the first link 30 is in this embodiment to mount the shaft 21. While for second link 40, second link 40 includes bushing 22, it is also understood that bushing 22 may comprise second link 40, or bushing 22 may comprise a portion of second link 40. In this embodiment, the sleeve 22 may be provided with a second through hole 23, and the rotating shaft 21 is further provided in the second through hole 23, or it may be understood that the sleeve 22 is sleeved on the rotating shaft 21 through the second through hole 23, so that the sleeve 22 can rotate along the rotation center of the rotating shaft 21 (i.e. the axis of the rotating shaft 21), and the sleeve 22 in the previous link assembly 20 rotates relative to the next link assembly 20.

Optionally, the diameter of the second through hole 23 is larger than the diameter of the rotating shaft 21. Therefore, the difficulty of sleeving the rotating shaft 21 by the sleeve 22 can be reduced, and the sleeve 22 can rotate relative to the rotating shaft 21 more easily.

Optionally, in order to prevent the link assemblies 20 from rotating randomly, the present embodiment may further include a damping structure provided in at least one of the rotating shaft 21 or the second through hole 23, wherein the damping structure is used to control the nth link assembly 20 to rotate around the rotating shaft 21 in the (N + 1) th link assembly 20 to a preset angle and stop rotating. Further alternatively, the damping structure may be a mechanical structure or a damping layer may be coated in the rotating shaft 21 or the second through hole 23 to increase the friction between the rotating shaft 21 and the sleeve 22.

Please refer to fig. 6, fig. 6 is a schematic structural diagram of a link assembly according to another embodiment of the present application. In this embodiment, the first link 30 further includes a stopper 34 connected to the base plate 31, and the stopper 34 is disposed near the rotation shaft 21. The sleeve 22 is further provided with a stop groove 41, and the blocking portion 34 is arranged in the stop groove 41.

While the above description describes that the damping structure may be provided in at least one of the rotating shaft 21 or the second through hole 23, the present application may also provide the damping structure in other portions. For example, the first link 30 in the present embodiment may further include a stopper 34 connected to the base plate 31, and the stopper 34 is disposed near the rotation shaft 21. The sleeve 22 may be provided with a stopper groove 41, and the stopper 34 may be disposed in the stopper groove 41. Thus, when the hinge structure 10 rotates, i.e. the sleeve 22 in the previous link assembly 20 rotates around the rotating shaft 21 in the next link assembly 20, after rotating to a predetermined angle, the blocking portion 34 abuts against the inner wall of the stop groove 41 to stop the rotation, thereby achieving the damping effect. Alternatively, the corresponding preset angle may be achieved by providing a specific structure of the blocking portion 34 and the stop groove 41.

Please refer to fig. 7, fig. 7 is a schematic structural diagram of a link assembly according to another embodiment of the present application. In this embodiment, the first link 30 further includes a first positioning portion 35, the first positioning portion 35 is disposed on the base plate 31, the second link 40 further includes a fixing portion 42 connected to the sleeve 22, a second positioning portion 43 is disposed on the fixing portion 42, and the first positioning portion 35 and the second positioning portion 43 cooperate with each other to movably connect the first link 30 to the second link 40.

In the present embodiment, the first positioning portion 35 may be provided on the base plate 31, the second positioning portion 43 may be provided on the fixing portion 42, and the first positioning portion 35 and the second positioning portion 43 may be engaged with each other to link the first link 30 and the second link 40 together. Alternatively, the first positioning portion 35 includes a slide groove or a slide bar 431, and the second positioning portion 43 includes a slide bar 431 or a slide groove. It is also understood that when the first positioning portion 35 is a slide groove, the second positioning portion 43 is a slide groove. When the first positioning portion 35 is the slide bar 431, the second positioning portion 43 is a slide groove. In the present embodiment, the first positioning portion 35 is a slide groove, and the second positioning portion 43 is a slide bar 431. Alternatively, the first positioning portion 35 and the second positioning portion 43 may cooperate with each other to movably connect the first link 30 with the second link 40, so that the distance between the first link 30 and the second link may be adjusted.

Referring to fig. 7 again, in the present embodiment, the first positioning portion 35 includes a sliding groove, and the second positioning portion 43 includes a sliding rod 431 and a nut 432; alternatively, the first positioning portion 35 includes a sliding rod 431 and a nut 432, and the second positioning portion 43 includes a sliding groove; the sliding rod 431 is disposed in the sliding groove, and the nut 432 is connected to the sliding rod 431, so that the sliding rod 431 can slide in the sliding groove along a direction (D2 direction in the figure) perpendicular to the arrangement direction of the plurality of link assemblies 20.

As can be seen from the above, when the flexible screen 3 is installed on the folding module 1, the folding module 1 drives the flexible screen 3 to bend together when bending, so as to achieve bending of the screen. However, when the flexible screen 3 is installed on the folding module 1, the rotation center of the flexible screen 3 usually cannot coincide with the rotation center of the folding module 1, that is, the rotation center of the flexible screen 3 cannot coincide with the axis of the rotating shaft 21, so that the flexible screen 3 and the folding module 1 do not rotate coaxially but do crank block motion when rotating. If the flexible screen 3 is of constant size, this will result in a change in the size of the hinge structure 10 to accommodate the slider-crank movement. In the present embodiment, the sliding between the first link 30 and the second link 40 is controlled to adjust the size of the link assembly 20 and the hinge structure 10. In order to realize that the first link 30 can be movably connected to the second link 40, in this embodiment, a nut 432 may be additionally provided, when the sliding rod 431 is engaged with the sliding slot, the nut 432 is used to connect the free end of the sliding rod 431, but a certain distance is reserved between the nut 432 and the sliding slot, so that the sliding rod 431 can slide in the sliding slot along a direction perpendicular to the arrangement direction of the plurality of link assemblies 20.

In this embodiment, the link assembly 20 further includes an elastic member 36, one end of the elastic member 36 is connected to the base plate 31, and the other end of the elastic member 36 is connected to the sleeve 22.

From the above, when the folding module 1 is provided with the flexible screen 3 and is bent, a slider-crank movement is usually performed. In this case, the first link 30 and the second link 40 not only slide in the direction perpendicular to the arrangement direction of the plurality of link assemblies 20, but also the distance between the first link 30 and the second link 40 in the direction parallel to the arrangement direction of the plurality of link assemblies 20 may be changed to accommodate the crank slider movement. In this embodiment, the elastic member 36 may be additionally provided, one end of the elastic member 36 is connected to the base plate 31, and the other end of the elastic member 36 is connected to the sleeve 22, so that when the folding module 1 is bent, the elastic member 36 is compressed to reduce the distance between the first link 30 and the second link 40. When the folding module 1 is unfolded, the elastic member 36 in the compressed state can give a rebound force to the first chain link 30 and the second chain link 40, so that the distance between the first chain link 30 and the second chain link 40 is increased to restore the folding module 1 to the unfolded state, and when the folding module 1 is restored to the unfolded state, the folding module 1 can be prevented from being folded backwards.

Please refer to fig. 9, fig. 9 is a schematic structural diagram of a folding module according to another embodiment of the present application.

The present embodiment may connect two adjacent hinge structures 10 by forming a fixing groove on the protruding portion 32 of the first link 30 in the link assembly 20 and installing the supporting shaft 50 in the fixing groove, so that the supporting shaft 50 is connected to the two adjacent hinge structures 10.

Referring to fig. 10 again, in the present embodiment, the vertical distance between the supporting shaft 50 and the base plate 31 is equal to the vertical distance between the rotating shaft 21 and the base plate 31. Alternatively, the present embodiment may also make the vertical distance between the support shaft 50 and the base plate 31 equal to the vertical distance between the rotating shaft 21 and the base plate 31. It can also be understood that the supporting shaft 50 and the rotating shaft 21 are at the same height, so that the supporting shaft 50 and the rotating shaft 21 can be prevented from being deviated when the folding module 1 is bent, thereby reducing the connection performance and stability of the folding module 1.
