Fig. 3 is a schematic diagram of a layer structure of an example of an electronic device in an unfolded state according to the present application. The electronic device is in an unfolded state, and if the electronic device is cut along the section Y-Y, a cross-sectional view of the layer structure shown in fig. 3 is obtained, and the present application describes a three-layer structure as a schematic diagram, which is not limited in the present application.
First, a layer structure of an electronic device will be briefly described. As shown in FIG. 3, the flexible screen assembly 10 shown in FIG. 3 is a flexible display screen, such as an OLED display screen. The flexible screen comprises a multi-layer structure, such as a cathode layer, an organic light emitting layer and an anode layer which are the most basic structures, and can also comprise an electron transport layer, a polarizer layer and the like. The flexible screen assembly 10 is fixedly connected to the two housings (center frame 20 and center frame 30).
The flexible screen assembly further comprises a PI layer 90 made of a transparent substrate, and the PI layer 90 is fixedly connected with the flexible screen assembly 10. The PI layer 90 may be a PI layer 90 made of a material having a certain flexibility and rigidity, such as thin glass, resin, etc. The PI layers 90 are fixedly connected to the middle frames, for example, by using a connection method such as dispensing.
The bending zone 40 of the flexible screen comprises a simplified turning structure. The flexible screen assembly 10 and the rotating structure can be fixedly connected in a dispensing manner. The reinforcing plate 50 and the flexible screen assembly 10 shown by the shaded portion are fixedly connected, for example, the reinforcing plate and the flexible screen assembly may be fixedly connected by means of glue dispensing, and the connection manner of the reinforcing plate and the flexible screen assembly is not limited in this application.
It should be understood that the reinforcing plate is a structural member of the electronic device, and the flexible screen assembly for reinforcing the electronic device may belong to one structural member of the flexible screen assembly.
The peripheries of the middle frame 20 (i.e., the first casing 20) and the middle frame 30 (i.e., the second casing 30) are fixedly connected with the flexible screen assembly 10, for example, the peripheries can be fixedly connected in a dispensing manner. Another portion of the middle frame 30 is adjacent to and fixedly attached to the rotating structure and another portion of the middle frame 20 is adjacent to and fixedly attached to the rotating structure.
The back cover 70 is fixedly connected to the middle frame 20 to form a middle frame assembly with the middle frame 20, and the back cover 80 is fixedly connected to the middle frame 30, which are structural members of the electronic device.
The slider 60 and the reinforcing plate 50 are fixedly connected, a dashed frame 301 is a sliding region of the slider 60, and the slider 60 can slide in the sliding region indicated by the dashed frame 301. In other words, the slider 60 can slide left and right along the X-axis of the coordinate axes.
Fig. 4 is a schematic diagram of a layer structure of an example of an electronic device in a folded state according to the present application. The connection relationship between the structural members is described in relation to fig. 3, and will not be described herein.
As shown in fig. 4, when the electronic device is in a folded state, because the flexible screen assembly includes multiple structural layers, the flexible screen assembly 10 may have an arching phenomenon due to the stress of the bending region when different layers of the flexible screen assembly 10 are bent. Meanwhile, the upper limit and the lower limit of the sliding block mechanism are realized in the Z-axis direction through the structure of the sliding groove, so that the displacement of the flexible screen assembly in the fitting direction is limited, and the problem of arching of the flexible screen is solved.
It will be appreciated that the delaminating slippage of the flexible screen, a phenomenon that must occur during bending, releases tension in a portion of the flexible screen assembly and thus helps to reduce the tension in the arching of a portion of the flexible screen, thereby helping to solve the problem of arching of the flexible screen.
In order to solve the arching problem that flexible screen appears at the in-process of buckling, this application embodiment provides the spacing subassembly of different design forms, provides the slip region through this spacing subassembly, combines the slider to form slider mechanism. And the reinforcing plate is pulled to drive the flexible screen assembly to move by the sliding of the sliding block in the sliding area. In the process that the reinforcing plate flexible screen assembly is pulled by the slider mechanism to move, when the electronic equipment is in an unfolded state, as shown in fig. 3, the slider 60 is close to the bending region 40; when the electronic apparatus is in the folded state, as shown in fig. 4, the slider 60 approaches the edge regions of the middle frames 30 and 20 along the sliding region 301 shown by the dashed line frame. The slidable distance of the slider 60 in the sliding region is designated as L2, and it is understood that L2 is greater than or equal to L1.
It will also be appreciated that whether the slider is slidable determines whether the laminar misalignment of the flexible screen assembly is smooth. In other words, the reinforcing plate is pulled to slide through the sliding of the sliding block, and the tension in the bending process is reduced. On the contrary, if the dislocation between the layers of the flexible screen assembly is not smooth, the tension in the bending process becomes very large, and even the flexible screen assembly is difficult to bend.
Specifically, this application will pull the stiffening plate through design slider mechanism and drive the motion of flexible screen subassembly to make flexible screen subassembly 10 be in free state at folding in-process, simultaneously, through the structure of sliding tray, realize spacing to slider mechanism in Z axle and Y axle direction, thereby restrict flexible screen subassembly 10 in laminating ascending position of side, can solve the problem that the screen arch camber.
First, various forms of the stop assembly provided herein are described.

Specifically, FIG. 5 is a cross-sectional view of a section Y-Y, and FIG. 6 is a cross-sectional view of a section X-X. The extent of the sliding region is limited by the middle frame 30 and the clip cylinder in the Y-axis direction, and the boundary of the sliding region 301 on the side close to the flexible screen assembly is the stiffening plate 50 and the boundary on the side away from the flexible screen assembly is the head boss of the clip 12 in the Z-axis direction. In other words, the clip 12 is fixed to the reinforcing plate 50, and forms a slide groove indicated by a dashed line 301 with the middle frame 30.
The spacing assembly shown in fig. 5, in combination with the slider, forms a sliding connection. Fig. 6 is a schematic view of an example of a slide coupling mechanism according to an embodiment of the present application. As shown in fig. 6, the slider 60 is formed as a structural member cover, and the slider 60 is locked to the reinforcing plate 50 by the clip 12, so that a slide groove indicated by a dashed line 301 is formed with the middle frame 30. The cover plate 60 is vertically restricted in a slide groove indicated by a dotted line frame 301 as a slider, but is slidable in the X-axis direction. Therefore, the limiting assembly and the fixing mode can realize that the slider can draw the reinforcing plate to freely slide in the X-axis direction, and simultaneously limit the position of the flexible screen assembly in the attaching direction, so that the problem of screen arching is solved.
Second limit component
In a possible spacing subassembly design, adopt buckle, fixed block as the connecting piece, the stiffening plate is as the structure, crosses the direct mode with fixed block sliding connection, fixed block and stiffening plate fixed connection of buckle and carries on spacingly.

As shown in fig. 7, the flexible screen assembly 10 is fixedly connected to the reinforcing plate 50, the latch 12 is slidably connected to the fixing block 13, and the fixing block is fixedly connected to the reinforcing plate 50.
Specifically, FIG. 7 is a sectional view of a section Y-Y, and FIG. 8 is a sectional view of a section X-X. In the Y-axis direction, the range of the sliding region is limited by the middle frame 30 and the clip cylinder, and in the Z-axis direction, the boundary of the side of the sliding region 301 close to the flexible screen assembly is the boundary of the fixing block 13, and the boundary of the side away from the flexible screen assembly is the head boss of the clip 12. In other words, the clip 12 is fixed to the reinforcing plate 50 together with the fixing block 13, and forms a sliding groove indicated by a broken line frame 301 with the middle frame 30.
The stop assemblies shown in fig. 7 and 8, in combination with the slider, form a sliding connection. Fig. 9 is a schematic view of an example of a slide coupling mechanism according to an embodiment of the present application. As shown in fig. 9, the structural member cover plate is used as the slider 60, the clip 12, the fixed block 13, and the center frame 30, and the slider 60 is limited in the sliding groove shown by the dashed line frame 301, thereby achieving the X-axis sliding. The cover plate 60 is vertically restricted in a slide groove indicated by a dotted line frame 301 as a slider, but is slidable in the X-axis direction. Therefore, the limiting assembly and the fixing mode can realize that the slider can draw the reinforcing plate to freely slide in the X-axis direction, and simultaneously limit the position of the flexible screen assembly in the attaching direction, so that the problem of screen arching is solved.
In a possible implementation, the connection region 304 between the fixing block 13 and the reinforcing plate 50 may be fixed by glue. It should be understood that the present application does not limit the type of glue used to connect the anchor block 13 and the stiffener 50, and does not limit the gluing process.
In another possible implementation, the connection region 304 between the fixing block 13 and the reinforcing plate 50 may be fixed by welding. It should be understood that the present application is not limited to any process of welding.
Combine above-mentioned embodiment and relevant attached drawing, through designing multiple possible slider mechanism, pull the reinforcing plate and drive flexible screen subassembly motion to make the flexible screen subassembly be in free state at folding in-process, simultaneously, through the structure of sliding tray, realize spacing from top to bottom to slider mechanism in the Z axle direction, thereby the position of restriction flexible screen subassembly in laminating side has solved the problem that the screen arch appears.
In addition, the arching condition of the flexible screen assembly during bending can be improved through the arranged limiting assembly. It will be appreciated that when the flexible screen assembly is arched, a portion of the area adjacent to its bend will be arched. Therefore, when each group of limiting assemblies is arranged, different numbers can be adopted, such as one or more (two or more) limiting assemblies are adopted to improve the arching condition of the flexible screen assembly.
It should also be understood that "fixedly attached" as used herein may be understood to refer to the attachment of the components by various means such as dispensing, welding, etc., and "slidably attached" may be understood to refer to the absence of attachment of the components by various means such as dispensing, welding, etc., e.g., the attachment of the spacing assembly to the housing by sliding.
Fig. 10 is a diagram of a relative position relationship between a limiting assembly and a flexible screen assembly according to an embodiment of the present application. When a spacing assembly is used, the spacing assembly 18 or 19 may be positioned adjacent the central axis of the flexible screen assembly 1100, as shown in figure 10. When a plurality of limiting assemblies are adopted, an array mode or a single-row arrangement mode can be adopted, however, no matter which mode is adopted, the arrangement direction of at least one row of the plurality of limiting assemblies is parallel to the axial direction of the shell when the shell is rotatably connected, and therefore the arching problem of the flexible screen assembly is solved.
It will be understood that where an element is described in embodiments herein as being "secured to" another element, it can be directly or indirectly secured to the other element; similarly, an element described in an embodiment of the present application as "connected" to another element may be directly connected or indirectly connected.
It is also understood that one direction described in the embodiments of the present application as being "parallel" or "perpendicular" to another direction may be understood as being "approximately parallel" or "approximately perpendicular".
It should also be understood that the limits in this application include, but are not limited to, displacement limits in the Z-axis, for example, the limit assembly may also be used to indicate a relationship of relative positions of multiple components.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
