Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The inventor of the application finds in the long-term research process that the flexible screen is generally formed by multilayer film lamination, when the flexible screen is driven by the driving part to be wound, the flexible screen is subjected to tensile stress, displacement can be generated between the multilayer film layers of the flexible screen, for example, at the winding tail end position, the film layer on the inner side in the flexible screen protrudes out of the film layer on the outer side, and the flexible screen has the risks of delamination and damage.
Based on this, the embodiment that this application provided can effectively solve the layering of flexible screen, damage problem, see in detail below.
Referring to fig. 1-2, fig. 1 is a schematic structural diagram of an embodiment of a winding mechanism of the present application, and fig. 2 is an exploded schematic diagram of an embodiment of the winding mechanism in fig. 1, where the winding mechanism 1 is used to drive a flexible screen to wind, the flexible screen may be an OLED flexible screen, a Micro-OLED flexible screen, or the like, and may include a display surface and a non-display surface that are oppositely disposed, and is generally formed by multiple laminated layers of films; for example, the flexible screen includes a flexible substrate, an array layer, a light emitting layer, an encapsulation layer, and the like, which are stacked, wherein one side of the encapsulation layer, which is away from the flexible substrate, may be defined as a display surface, a user may see display information from one side of the display surface of the flexible screen, one side of the flexible substrate, which is away from the encapsulation layer, may be defined as a non-display surface, and the user may not see the display information from one side of the non-display surface of the flexible screen. In this embodiment, the winding mechanism 1 for winding the flexible screen includes a flexible support 10, a pull bar 12, and a drive assembly 14 (shown in FIG. 2).
In particular, the flexible support 10 comprises a first surface 100 and a second surface 102 which are oppositely arranged, and the flexible screen may be arranged on the first surface 100, for example, a non-display surface of the flexible screen may be fixedly connected with at least part of the first surface 100 of the flexible support 10. During the winding process, the flexible support 10 may be wound together with the flexible screen, and the material of the flexible support 10 may be rubber or the like having elasticity. The flexible support 10 includes a winding start end 104 and a winding end 106 which are oppositely disposed, and in the present embodiment, the winding start end 104 and the winding end 106 may be two oppositely disposed side surfaces connected to the first surface 100.
The pulling string 12 extends in a direction from a winding start 104 to a winding end 106 of the flexible support 10 (as indicated by the dotted arrow in fig. 1 and 2) and is connected to the flexible support 10. The braces 12 may be flexible and meet certain fatigue and tensile strength, and may be sheet metal, plastic, etc. The driving assembly 14 includes a first driving member 140 and a second driving member 142 (as shown in fig. 2), the first driving member 140 is used for driving the flexible support 10 and the flexible screen to wind, the second driving member 142 is used for driving the pulling strip 12 to wind, so as to pull the flexible support 10 toward the winding start end 104 (i.e. the direction opposite to the dotted arrow in fig. 2) during the winding process of the flexible support 10, and further, the winding stroke of the flexible support 10 is greater than the winding stroke of the flexible screen. In this embodiment, the first driving member 140 may be a first motor, and the second driving member 142 may be a second motor.
In the winding process, the winding stroke of the flexible support 10 is greater than that of the flexible screen, and the existence of the stroke difference can enable the flexible support 10 to provide a pulling force to one side surface (i.e. the non-display surface) of the flexible screen in contact with the first surface 100 of the flexible screen, and the pulling force can offset or reduce the acting force between the films of the flexible screen in the winding process, so that the one side surface (i.e. the non-display surface) of the flexible screen contracts, and the displacement degree (i.e. the relative offset distance) between the one side surface (i.e. the non-display surface) and the other side surface (i.e. the display surface) is reduced, thereby reducing the probability of the delamination between the multiple films of the flexible screen in the winding process, reducing the damage probability of the flexible screen, and prolonging the service. In one application scenario, the pulling force may be controlled by controlling the rotation speed of the second motor (i.e., the second driving member 142) so that the pulling force is within the allowable stress range of the flexible screen.
Fig. 3a to 3b are taken as an example for explanation, wherein fig. 3a is a schematic structural diagram of an embodiment of a portion of a flexible screen at the winding end in the prior art, and fig. 3b is a schematic structural diagram of an embodiment of a portion of a flexible screen at the winding end after winding by using the winding mechanism in fig. 1. As can be seen from the figure, in the prior art, there is a relatively serious relative displacement between the display surface 200 and the non-display surface 202 of the flexible screen 20, that is, the non-display surface 202 in the inner layer protrudes from the display surface 200 along the winding direction; when the design provided by the present application is adopted, the displacement degree between the display surface 200a and the non-display surface 202a of the flexible screen 20a is significantly reduced.
In one embodiment, referring to fig. 1 and 2 again, a channel 108 (as shown in fig. 2) extending along a direction from the winding start 104 to the winding end 106 of the flexible support 10 is disposed inside the flexible support 10, the pull strip 12 is disposed in the channel 108, and a first position-limiting portion 120 is disposed at a position of the pull strip 12 close to the winding end 106, so that the pull strip 12 is not separated from the channel 108. In one application scenario, first stop 120 may be located at the end of brace 12, and the width of first stop 120 may be greater than the width of channel 108 and protrude outside of channel 108, so that brace 12 does not disengage from channel 108. The brace 12 is simple in design and structure and easy to realize in process. Of course, in other embodiments, the pull-string 12 may be fixedly disposed on the second surface 102 of the flexible support 10.
In yet another embodiment, as shown in FIG. 4, FIG. 4 is a schematic cross-sectional view of an embodiment of a portion of FIG. 1 shown in phantom. The second surface 102 of the flexible support 10 includes a plurality of grooves 101 arranged at intervals along a direction from a winding start 104 to a winding end 106 of the flexible support 10, and a protrusion 103 is provided between two adjacent grooves 101. The extending direction of the groove 101 may be perpendicular to the direction from the winding start 104 to the winding end 106 of the flexible support 10, and the groove 101 may extend from one side to the other side of the flexible support 10 (as shown in fig. 2). In the embodiment shown in fig. 4, groove 101 is in communication with channel 108 (not shown in fig. 4), although groove 101 may not be in communication with channel 108 in other embodiments. The grooves 101 divide the second surface 102 of the flexible support 10 into a plurality of protuberances 103; wherein, some bulges 103 are provided with accommodating holes (not labeled), the accommodating holes are communicated with the channel 108, the position of the brace 12 corresponding to the accommodating holes is provided with a limiting column 122, and the limiting column 122 can be inserted into the accommodating holes. In the present embodiment, the shape of the receiving hole matches the shape of the limiting post 122, for example, each of the receiving hole and the limiting post may be a cylinder, a prism, or the like. There is no gap between the position-limiting column 122 and the accommodating hole, or there is a gap between the position-limiting column 122 and the accommodating hole, and the gap is only located at the side close to the winding start end 104. During the winding process of the flexible support 10, the brace 12 can make the width d1 of the groove 101 itself narrow and the distance between adjacent grooves 101 shorten, so that the stroke difference between the flexible support 10 and the flexible screen is larger, and the displacement degree between the multiple film layers of the flexible screen is reduced; in addition, the design mode of the limiting columns 122 on the pulling strips 12 and the accommodating holes on the flexible support 10 can make the pulling force of the pulling strips 12 on the flexible support 10 be larger, so that the pulling force of the flexible support 10 on the flexible screen is improved.
In one application scenario, the height of the limiting column 122 is smaller than or equal to the depth of the accommodating hole. This design can make winding mechanism 1 relatively pleasing to the eye, and can make flexible support piece 10 drive when flexible screen convolutes can not unsmooth between adjacent layer, reduces the damage to the flexible screen.
In still another application scenario, as shown in fig. 2 and 4, the accommodating holes are disposed on one portion of the protrusions 103, the accommodating holes are not disposed on the other portion of the protrusions 103, and the protrusions 103 without accommodating holes and the protrusions 103 with accommodating holes are alternately arranged. This design can make flexible support element 10 atress comparatively even when contracting to make flexible support element 10 comparatively all to the power of dragging of flexible screen.
In a further application scenario, bar 12 comprises a first portion 124 corresponding to boss 103 not provided with a receiving hole, there being a gap (not identified) between first portion 124 and the inner wall of channel 108, i.e. there is no contact between first portion 124 and its corresponding inner wall of channel 108, the dimensions of first portion 124 being smaller than the dimensions of its corresponding channel 108. The design mode of the gap can reduce the friction between the brace 12 and the channel 108 during the winding motion, is beneficial to the protrusion 103 with the containing hole to approach to the protrusion 103 without the containing hole, finally enables the winding stroke of the flexible supporting piece 10 to be larger than that of the flexible screen, and further can reduce the displacement difference between the multilayer films of the flexible screen. For other portions of the braces 12, there may or may not be a gap between the side of the first surface 100 adjacent to the flexible support 10 and the inner wall of the channel 108, which is not limited in this application.
In a further application scenario, the winding mechanism further includes an adhesive member 13 covering a portion of the first surface 100 corresponding to the protrusion 103 provided with the receiving hole, a portion of the first surface 104 corresponding to the groove 101 may not be provided with the adhesive member 13, and/or a portion of the first surface 104 corresponding to the protrusion 103 not provided with the receiving hole may not be provided with the adhesive member 13. This design allows the flexible support 10 to be easily retracted by the brace 12 while still securing the flexible support 10 to the flexible screen.
In yet another embodiment, referring again to fig. 2, the number of channels 108, braces 12 and second driving members 142 mentioned in the above embodiment is the same, and corresponds to one another; wherein, the number of the channels 108 is one, and the channels are located on the central axis (shown as a dashed straight line in fig. 2) of the flexible support 10; alternatively, the number of the channels 108 is multiple and is symmetrically arranged along the central axis of the flexible support 10; for example, when the number of channels 108 is even, the channels 108 may be symmetrically disposed on both sides of the central axis of the flexible support 10; when the number of the passages 108 is odd, one of the passages 108 may be located on the central axis of the flexible support 10, and the other passages 108 may be symmetrically disposed on both sides of the central axis of the flexible support 10. The above design can make the force of the stay 12 on the flexible support 10 more uniform.
In another embodiment, referring to fig. 2, the first driving member 140 and the second driving member 142 of the driving assembly 14 can be fixedly connected, for example, the second driving member 142 can be fixed to the first driving member 140 by a fixing member, so that when the first driving member 140 rotates, the second driving member 142 is driven to rotate synchronously, and the pulling bar 12 is driven to wind together with the second driving member 142. The first driving member 140 and the second driving member 142 are simple in design and structure, and the power consumption is relatively reduced. In addition, in the present embodiment, the volume of the first driver 140 may be larger than that of the second driver 142 in view of reducing the volume of the winding mechanism 1. In this embodiment, while the second driving member 142 rotates with the first driving member 140, the second driving member 142 itself has a rotation speed, and when the diameter of the first driving member 140 is larger than that of the second driving member 142, the rotation speed of the first driving member 140 may be smaller than that of the second driving member 142; conversely, the rotational speed of the first driving member 140 may be greater than the rotational speed of the second driving member 142.
Of course, in other embodiments, the first driving member 140 and the second driving member 142 may be independent from each other and not fixedly connected, in which case, the diameters of the first driving member 140 and the second driving member 142 may be the same, and the rotation speed of the second driving member 142 may be higher than that of the first driving member 140 in order to make the stroke difference between the flexible screen and the flexible supporting member 10.

The fixing piece can be an adhesive or other fixing structures and the like, and the application does not limit the fixing piece. The above design can reasonably utilize the space, so that the volume occupied by the winding mechanism 1 is small.
In yet another embodiment, with continued reference to fig. 1 and 2, the winding mechanism 1 provided herein further includes a housing 11 having a second cavity 110, and the winding drum 16 and the flexible support member 10 are located in the second cavity 110.
