Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and more particularly to display screen assemblies and electronic equipment. Background Technology

[0002] A typical application of flexible screens is in the fabrication of foldable display assemblies, which are used in foldable electronic devices such as foldable phones and tablets. Typically, such foldable display assemblies include: a first shell, a second shell, a hinge connecting the first and second shells to allow them to unfold and fold, and a flexible screen simultaneously laid on both the first and second shells. When the first and second shells are folded, the flexible screen bends in the area corresponding to the hinge, achieving synchronous folding. When the first and second shells are unfolded, the flexible screen also unfolds synchronously.

[0003] In existing technologies, flexible screens are fixedly laid on two shells simultaneously, for example, by adhesive bonding. A typical drawback of this installation method is that, on the one hand, during the folding of the two shells, the deformation of the hinges pulls on the flexible screen, i.e., it exerts tension. Since other areas of the flexible screen are fixed to the shells, the area corresponding to the hinge is stretched. Under frequent folding conditions, the elastic deformation of the flexible screen in that area will fail, resulting in permanent elongation of that area and noticeable wrinkles when flattened. On the other hand, during the unfolding of the two shells, the deformation of the hinges exerts a pushing force on the flexible screen. Since other areas of the flexible screen are fixed to the shells, this further exacerbates the wrinkling problem in that area.

[0004] To address the aforementioned issues, existing technology provides a method for installing flexible screens. This method involves configuring a movable plate within one of the shell panels. This movable plate can slide along the length of the flexible screen, which is then attached and fixed to it. During the folding of the two shell panels, the movable plate slides towards the hinge to effectively prevent excessive tension on the flexible screen from the hinge. Conversely, during the unfolding of the two shell panels, the movable plate slides away from the hinge to effectively prevent excessive pushing force from the hinge on the flexible screen. This gives the flexible screen a degree of flexibility, thereby effectively improving the flatness of the area corresponding to the hinge and the flexible screen in the unfolded state.

[0005] However, the above-mentioned flexible screen installation method still has the following problems:

[0006] 1. The movable plate is assembled onto the shell in contact with it. The sliding of the movable plate requires overcoming the friction between the movable plate and the shell. This friction is difficult to determine during the design phase, and assembly errors can affect its magnitude. Furthermore, the friction can change significantly over long-term use. If the friction increases after use, it greatly affects the compliance of the flexible plate, especially its compliance with the movement of the flexible screen towards the far end of the shell (away from the hinge) during deployment. Although existing technologies attempt to improve the compliance of the flexible screen towards the far end of the shell by adding a spring between the movable plate and the shell, if the friction is high, while the spring improves the compliance towards the shell end, it reduces the compliance of the flexible screen towards the hinge.

[0007] 2. The springs provided in the prior art for improving compliance when moving towards the far end of the plate are typically cylindrical springs and torsion springs. Springs with this structure tend to cause uneven movement of the moving plate, that is, they may generate forces in the width direction on the moving plate. Furthermore, these springs are only used to improve compliance and do not have any other function. Summary of the Invention

[0047] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0048] The present invention discloses a display assembly that is assembled and applied to a foldable electronic device, such that the electronic device has a panel that serves entirely as a display screen when in the open state.

[0049] like Figures 1 to 5 As shown, the display assembly includes: a shell body having a first shell 21 and a second shell 22, a hinge 14, a flexible screen 10, a movable plate 30, a fixed plate 60, and a conforming component 40.

[0050] The first shell 21 and the second shell 22 each have adjacent proximal ends and distant distal ends. A hinge 14 is disposed between the proximal ends of the first shell 21 and the second shell 22. This hinge 14 is configured as a flexible connection structure, so that the first shell 21 and the second shell 22 can be unfolded and folded by means of the deformation of the hinge 14. During the folding process, the hinge 14 deforms as follows: Figure 4 The shape shown is an arc-shaped curve, and after being flattened, it resembles... Figure 1 As shown, hinge 14 returns to its plate-like state.

[0051] The first shell 21 can serve as a motherboard shell, and its interior can be used to install functional components such as printed circuit boards of electronic devices (not shown). The first shell 21 can be electrically connected to the components in the second shell 22 through wires passing through the hinge 14.

[0052] The flexible screen 10 simultaneously covers the first shell 21 and the second shell 22, specifically, as shown in the figure. Figure 1As shown, the flexible screen 10 has a first component adapted to the first shell 21, a second component adapted to the second shell 22, and an intermediate portion 13 located between the first component and the second component relative to the hinge 14. After the first shell 21 and the second shell 22 are unfolded, the three parts of the flexible screen 10 unfold synchronously. After the first shell 21 and the second shell 22 are folded, the intermediate component bends synchronously with the hinge 14, thereby switching the first part 11 and the second part 12 of the flexible screen 10 to a folded state. During the folding process of the first shell 21 and the second shell 22, the deformation of the hinge 14 pulls on the two parts, that is, it applies a pulling force to the flexible screen 10. During the opening process of the first shell 21 and the second shell 22, the restoring deformation of the hinge 14 applies a pushing force to the two parts of the flexible screen 10. If both parts of the flexible screen 10 are attached and fixed to the two shells, the intermediate portion 13 of the flexible screen 10 will develop relatively severe wrinkles after long-term use.

[0053] A groove is formed on the front surface of the second shell 22. The fixed plate 60 is attached to the bottom of the groove. The movable plate 30 is located above the fixed plate 60. By reasonably setting the structure of the second shell 22, the movable plate 30 has a certain amount of mobility in the length direction of the flexible screen 10 (i.e., in the direction between the near end and the far end of the second shell 22). The back side of the second part 12 of the flexible screen 10 is attached to the movable plate 30.

[0054] The compliant member 40 is disposed between the movable plate 30 and the fixed plate 60 and connected to both respectively. The compliant member 40 is made of a flexible material, such as some polymers, or even silicone, so that the compliant member 40 can deform in the length direction of the flexible screen 10. In this way, the movable plate 30 can move relative to the fixed plate 60 toward the proximal or distal end of the second shell 22 through the compliant member 40. At this time, the movable plate 30 does not contact the fixed plate 60 and is allowed to move only through the deformation of the compliant member 40. Thus, during the folding process of the first shell 21 and the second shell 22, the compliant component 40 deforms towards the proximal end of the second shell 22, allowing the movable plate 30 to move towards the proximal end of the second shell 22, thereby effectively preventing excessive traction on the flexible screen 10 due to the bending deformation of the hinge 14; and during the opening process of the first shell 21 and the second shell 22, the compliant component 40 deforms towards the distal end of the second shell 22, allowing the movable plate 30 to move towards the distal end of the second shell 22, thereby effectively preventing excessive thrust on the flexible screen 10 due to the reset deformation of the hinge 14.

[0055] The present invention uses a compliant member 40 to separate the movable plate 30 from the second shell 22, and uses the deformation of the compliant member 40 to allow the movable plate 30 to move. This effectively avoids the uncertain frictional force generated by the movable plate 30 due to contact with the second shell 22, which is easily affected by assembly errors and usage time. The compliant member 40 provides damping that allows the movable plate 30 to move. This damping is at least easily determined, for example, at least through testing, and is less affected by assembly and usage time.

[0056] A preferred embodiment of the present invention provides a compliant component 40 of a structure, such as Figure 1 and Figure 2 As shown, the conforming component 40 includes flat tubular components 41 spaced apart along the length of the flexible screen 10. These flat tubular components 41 extend in the width direction of the flexible screen 10, with both ends of the flat tubular components 41 close to the sides of the movable plate 30. The flat tubular components 41 are made of silicone material, and their cross-sectional structure consists of an integrally formed upper wall 411, a lower wall 412, and an arc-shaped sidewall 413 between the upper wall 411 and the lower wall 412. The upper wall 411 is attached and fixed to the movable plate 30; however, the upper wall 411 is not entirely attached and fixed to the movable plate 30, but only the middle region is attached and fixed to the movable plate 30, and the lower part is attached and fixed to the fixed plate 60. Similarly, the lower wall 412 is not entirely attached and fixed to the fixed plate 60, but only the middle region is attached and fixed to the fixed plate 60. Thus, the upper wall 411... 11. The two sides of the lower wall 412, that is, the area where it intersects with the arc-shaped side wall 413, are not fixed. Thus, during the folding process, when the flexible plate is pulled by the bending deformation of the hinge 14, the upper wall 411 and the lower wall 412 are transformed into the arc-shaped side wall 413, and the arc-shaped side wall 413 is transformed into the upper wall 411 and the lower wall 412, similar to the ring-shaped component rolling a certain amount, thereby conforming to the pull. Correspondingly, during the unfolding process, when the flexible plate is pushed by the reset deformation of the hinge 14, the flat tubular component 41 should also conform to the thrust in the same way.

[0057] The compliant component 40 of the above structure has at least the following advantages:

[0058] 1. The flat tubular conforming component 40 allows the movable plate 30 to have a large displacement by means of a rolling deformation.

[0059] 2. The flat tubular conforming component 40 allows the movable plate 30 to move along the length of the flexible screen 10 while also supporting the movable plate 30 in the thickness direction.

[0060] 3. The flat tubular conforming component 40, through a rolling-like deformation method, ensures that after the movable plate 30 moves, the vertical support force of the conforming component 40 on the movable plate 30 does not change much compared to the support force before the movement.

[0061] 4. The flat, tubular conforming component 40 is easier to manufacture.

[0062] In some preferred embodiments of the present invention, such as Figure 3 , 5 As shown in Figures 6 and 7, an elastic component 50 is also provided between the movable plate 30 and the fixed plate 60. There are two elastic components 50, which are located on both sides of the movable plate 30 and the fixed plate 60 along the length direction of the flexible screen 10. Specifically, the elastic member 50 includes a shaft-shaped member 51 and two elastic strips 52; the shaft-shaped member 51 is arranged in the same direction as the aforementioned flat tubular member 41; the elastic strips 52 are structurally configured such that their cross-section has an arc-shaped curved section 521 and a straight connecting section 522; the curved section 521 covers the outer peripheral surface of the shaft-shaped member 51, and the free end of the curved section 521 is attached and fixed to the shaft-shaped member 51, and the curved sections 521 of the two elastic strips 52 cover the shaft-shaped member 51 from two radial directions, such that the connecting sections 522 of the two elastic strips 52 face opposite directions, that is, the free end of one connecting section 522 faces the proximal end of the second shell 22 and is located above, and the free end of the other connecting section 522 faces the distal end of the second shell 22 and is located below, and the upper connecting section 522 is attached and fixed to the movable plate 30, and the lower connecting section 522 is attached and fixed to the fixed plate 60. Thus, as Figure 3 and Figure 5 As shown, the elastic strip 52 applies an elastic force to the movable plate 30 in the length direction of the flexible screen 10 through the unfolding deformation and curling reset of the bending section 521, while simultaneously allowing the movable plate 30 to move.

[0063] During the folding process, such as Figure 5 As shown, the elastic strip 52, through the unfolding of its bent section 521, allows the movable plate 30 to move towards the proximal end of the second shell 22, thereby conforming to the pull of the flexible screen 10; and during the folding process, as Figure 5 As shown, the elastic strip 52 pulls the movable plate 30 toward the far end of the second shell 22 by curling and resetting its bent section 521, thereby avoiding the resetting action of the hinge 14 from generating a thrust on the flexible screen 10.

[0064] Other advantages of the elastic component 50 include:

[0065] 1. During the unfolding process of the two shells, the pulling effect on the movable plate 30 generated by the curling and resetting of the bending section 521 of the elastic strip 52 can effectively overcome the damping of the movable plate 30 by the conforming component 40, thereby preventing the central area of ​​the flexible screen 10 from wrinkling due to the thrust by pulling the movable plate 30.

[0066] 2. The elastic component 50 is arranged in the width direction of the flexible screen 10 and mainly applies force in the length direction of the flexible screen 10. This is beneficial for the movable plate 30 to be mainly subjected to force in the length direction, thereby improving the force distribution of the movable plate 30 and making it more balanced and stable.

[0067] In some preferred configurations, annular grooves 513 are engraved on the outer peripheral surface of the shaft-shaped member 51; multiple annular grooves 513 are arranged at intervals along the axial direction of the shaft-shaped member 51; multiple elastic legs 5211 are engraved on the curved section 521 of the elastic member 50, and the multiple elastic legs 5211 are arranged at intervals along the axial direction of the shaft-shaped member 51 and correspond one-to-one with the multiple annular grooves 513; the elastic legs 5211 are enclosed in the annular grooves 513, and the ends of the elastic legs 5211 are attached and fixed to the bottom of the annular grooves 513. In this way, on the one hand, the curved section 521 of the elastic member 50 will not contact the movable plate 30 and the fixed plate 60 when deployed, and will not generate forces in complex directions; on the other hand, the shaft-shaped member 51 also provides support for the movable plate 30. In a more preferred configuration, the shaft-shaped component 51 includes a conductive core 511 and an elastic insulating layer 512 covering the conductive core 511; the annular groove 513 is etched to such depth that the bottom of the groove extends through to the conductive core 511, thereby electrically connecting the elastic leg 5211 to the conductive core 511; an upper terminal plate 71 is provided at the bottom of the movable plate 30, and a lower terminal plate 72 is provided on both the fixed plate 60; the connecting section 522 of the elastic strip 52 is welded to the upper terminal plate 71 and the lower terminal plate 72. The elastic component 50 is configured as a conductor, thereby enabling essential electrical connections between the flexible screen 10 and other functional components (e.g., printed circuit boards) through the elastic component 50.
