DETAILED DESCRIPTION

[0041] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent identical or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0042] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0043] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0044] The present disclosure provides a scrolling display device. As shown in Figures 1 to 12 , the scrolling display device comprises a fixed housing 1, a sliding housing 2, an elastic assembly 3, and a snap-fit ​​assembly 4. The sliding housing 2 is slidably connected to a side of the fixed housing 1 extending in a first direction. The elastic assembly 3 includes a first elastic member 33, one end of which abuts the fixed housing 1 and the other end abuts the sliding housing 2. The snap-fit ​​assembly 4 is used to connect the sliding housing 2 to the fixed housing 1.

[0045] When the snap assembly 4 connects the sliding housing 2 to the fixed housing 1, the first elastic member 33 of the elastic assembly 3 is in a compressed state. When the snap assembly 4 separates the sliding housing 2 from the fixed housing 1, the first elastic member 33 pushes the sliding housing 2 to slide relative to the fixed housing 1, causing the sliding housing 2 to move away from the fixed housing 1 in a first direction, driving the flexible display panel 6 to unfold and increase the display area of ​​the flexible display panel 6. As the modulus of the flexible display panel changes, the driving force provided by the first elastic member 33 also changes accordingly. During the unfolding process of the sliding display device, the driving force that adapts to the modulus of the flexible display panel is always provided, thus minimizing the impact on the service life of the flexible display panel.

[0046] The scrolling display device according to the embodiment of the present disclosure will be described in detail below with reference to specific examples.

[0047] As shown in Figures 1 to 5, the scrolling display device includes a fixed housing 1, which is a rectangular structure. The fixed housing 1 includes a support plate 11 and two guide plates 12. The support plate 11 includes two mutually parallel first sides and two mutually parallel second sides. The first side extends along a first direction, and the second side extends along a second direction. The length of the first side is greater than the length of the second side. The two guide plates 12 are respectively provided on the two first sides of the support plate 11, and the plane on which the guide plates 12 are located is perpendicular to the plane on which the support plate 11 is located. It should be noted that the second direction is perpendicular to the first direction, and the third direction is perpendicular to the first and second directions. The first direction is the x-direction in Figure 1, and the second direction is the y-direction in Figure 1.

[0048] The scrolling display device also includes two sliding housings 2, which are disposed on either side of the fixed housing 1 along a first direction, that is, the two sliding housings 2 are disposed adjacent to the two second sides of the fixed housing 1. The sliding housings 2 include sliding plates 21, connecting arms 22, and connecting plates 23. The connecting arms 22 extend along the second direction, while the sliding plates 21 extend along the first direction. The sliding plates 21 are disposed at both ends of the connecting arms 22 and extend toward the side closest to the fixed housing 1. The connecting plate 23 is located between the two connecting arms 22 and extends toward the side closest to the fixed housing 1 along the first direction. Tracks are provided on both guide plates 12 of the fixed housing 1, and the two sliding plates 21 are slidably connected within the tracks.

[0049] The scrolling display device further includes multiple pairs of elastic components 3 arranged sequentially along the second direction. Each pair of elastic components 3 includes two elastic components 3, and the two elastic components 3 are symmetrically arranged about a centerline extending along the second direction of the fixed housing 1. To prevent interference between the two elastic components 3, the size of the installation area of ​​the elastic components 3 in the first direction is reduced, and the two elastic components 3 in a pair of elastic components 3 are arranged along the first direction.

[0050] As shown in Figure 6, the fixed housing 1 is provided with a mounting cavity 13, and the elastic assembly 3 is disposed within the mounting cavity 13. The elastic assembly 3 includes a mounting seat 31, a first elastic member 33, and a guide post 32. The mounting seat 31 is disposed within the mounting cavity 13, and the guide post 32 is fixed to the mounting seat 31 and extends along a first direction. The two mounting seats 31 in a pair of elastic assemblies 3 are disposed opposite to each other, so that the extension directions of the two guide posts 32 in a pair of elastic assemblies 3 are opposite in the first direction. The first elastic member 33 can be a spring, which is sleeved on the guide post 32. The mounting seat 31 is provided with a through hole, the center of which is located on the center line of the guide post 32. The first elastic member 33 passes through the through hole and abuts against the sliding housing 2. It should be noted that abutment refers to the first elastic member 33 being in close contact with the sliding housing 2. When the first elastic member 33 abuts against the sliding housing 2, the first elastic member 33 has a certain amount of deformation.

[0051] To prevent the first elastic member 33 from dislodging from the guide post 32, the sliding display device further includes a spring seat 34. The spring seat 34 extends through the through hole and into the mounting seat 31. A stopper 341 is provided on the end of the spring seat 34 facing away from the sliding housing 2. The stopper 341 is larger than the through hole. One end of the first elastic member 33 maintains constant contact with the bottom of the mounting seat 31, while the other end maintains constant contact with the bottom of the spring seat 34.

[0052] As shown in Figures 7 to 9, the sliding display device also includes a snap assembly 4, which includes a push rod 43, a first snap member 41, and a second snap member 42. The push rod 43 passes through the side wall of the fixed housing 1 and extends into the side of the fixed housing 1 near the elastic assembly 3. The middle portion of the second snap member 42 is rotatably connected to the fixed housing 1. The transition positions of the two second snap members 42 are located on both sides of the push rod 43 along the first direction. The portion of the second snap member 42 located between the two transition positions is slidably connected to the push rod 43, that is, the end of the second snap member 42 away from the first snap member 41 is slidably connected to the push rod 43, and the two second snap members 42 are slidably connected to the same position on the push rod 43. The first snap member 41 is fixed to the connecting plate 23 of the sliding housing 2. When the two sliding housings 2 move toward the fixed housing 1, the first snap member 41 approaches the second snap member 42.

[0053] The clamping assembly 4 also includes a pin 47. The second clamping member 42 is provided with a waist-shaped hole extending in the first direction, and the push rod 43 is provided with a first connecting hole 431. The pin 47 passes through the waist-shaped hole and the first connecting hole 431, connecting the second clamping member 42 and the push rod 43 together. When the second clamping member 42 rotates relative to the fixed housing, the pin 47 slides and rotates within the waist-shaped hole 425, thereby defining the rotational trajectory and travel of the second clamping member 42. It should be noted that the waist-shaped hole 425 includes two parallel straight wall segments and an arcuate wall connecting the two straight wall segments.

[0054] To ensure that the push rod 43 can effectively rebound after pushing the second clamping member 42, the clamping assembly 4 also includes a second elastic member 44, a first stopper 45, and a second stopper 46. The second elastic member 44 abuts between the first stopper 45 and the second stopper 46. The first stopper 45 is fixedly connected to the fixed housing 1, and the second stopper 46 is fixedly connected to the push rod 43. The second stopper 46 has a protrusion 461 that extends from the side wall of the fixed housing 1. The first stopper 45 includes a connecting structure 451. The first stopper 45 is connected to the fixed housing 1 via two connecting structures 451. The second stopper 46 is located between the two connecting structures 451. The size of the first stopper 45 is less than or equal to the distance between the two connecting structures 451.

[0055] The first clamping member 41 is a first hook, and the second clamping member 42 is a second hook. The first clamping member 41 includes a first fixing portion 411, a first connecting portion 412 and a first clamping portion 413. The first fixing portion and the first connecting portion 412 both extend along the first direction, and the first clamping portion 413 extends along the second direction. The size of the first connecting portion 412 along the second direction is smaller than the size of the first fixing portion along the second direction. The first fixing portion and the first clamping portion 413 form a first slot 414.

[0056] The second clamping member 42 includes a second fixing portion 421, a second connecting portion 422, and a second clamping portion 423. The second fixing portion 421 and the second connecting portion 422 both extend in the first direction, and the second clamping portion 423 extends in the second direction. The second connecting portion 422 has a smaller dimension in the second direction than the second fixing portion 421. The second fixing portion 421 and the second clamping portion 423 form a second clamping slot 424. When the second clamping member 42 is connected to the first clamping member 41, the first clamping portion 413 is located in the second clamping slot 424, and the second clamping portion 423 is located in the second clamping slot 424.

[0057] The first engaging portion 413 has a first inclined surface 415 on a side away from the first fixing portion 411, and the second engaging portion 423 has a second inclined surface 426 on a side away from the second fixing portion 421 that matches the first inclined surface 415. It should be noted that the second engaging member 42 is connected to the push rod 43 and the fixed housing 1 via the second fixing portion 421.

[0058] In other feasible embodiments, a first clip 41 may be provided on one of the sliding housings 2 and fixedly connected to the sliding housing 2, a second clip 42 may be provided on the other sliding housing 2, a push rod 43 may be passed through the side wall of the sliding housing 2, the second clip 42 may be connected to the side of the push rod 43 close to the first clip 41 along the first direction, the middle portion of the second clip 42 may be rotationally connected to the sliding housing 2, and the end of the second clip 42 away from the first clip 41 may be slidably connected to the push rod 43. The structure and arrangement direction of the first clip 41 and the second clip 42 are the same as those mentioned above and will not be further described here.

[0059] As shown in Figure 10, the scrolling display device further includes a support mechanism comprising a plurality of folding link assemblies 5. The folding link assemblies 5 include a plurality of hinged links 51. The links 51 at each end of each folding link assembly 5 respectively connect the fixed housing 1 and the sliding housing 2. As the sliding housing 2 moves away from the fixed housing 1 in a first direction, the angle between two adjacent links 51 gradually increases, and the folding link assemblies 5 gradually unfold.

[0060] The folding link assembly 5 further includes rivets 53. Connecting portions 511 are provided at both ends of the link 51. The connecting portions 511 are provided with second connecting holes. The rivets 53 pass through the second connecting holes to connect two adjacent links 51. The two links 51 can rotate relative to the rivets 53 to change the angle between them. It is understood that multiple links 51 can be hinged together using multiple rivets 53.

[0061] The folding link assembly 5 also includes a torsion spring 52, which is sleeved onto a rivet 53. When the clamping assembly 4 separates the sliding housing 2 from the fixed housing 1, the sliding housing 2 slides away from the fixed housing 1, the angle between the two adjacent links 51 gradually increases, and the torsion spring 52 gradually relaxes, squeezing the two adjacent links 51, causing the support mechanism to gradually transition from a tightened state to a supported state. When the sliding housing 2 is manually pushed to slide toward the fixed housing 1, the two adjacent links 51 squeeze the torsion spring 52, causing it to gradually tighten, gradually reducing the angle between the two adjacent links 51, and gradually transitioning the support mechanism from a supported state to a tightened state.

[0062] Referring again to Figures 1 to 5 , the scrolling display device further includes a flexible display panel 6. The flexible display panel 6 is partially affixed to a side of the fixed housing 1 facing away from the elastic component 3 and is wound along the support mechanism to a side of the fixed housing 1 facing the elastic component 3. The flexible display panel 6 is capable of sliding relative to the sliding housing 2. The scrolling display device further includes a flexible support plate 7 affixed to the flexible display panel. The flexible support plate 7 is partially positioned between the support mechanism and the flexible display panel, and partially positioned between the sliding housing 2 and the flexible display panel. Because the flexible display panel 6 slides synchronously with the sliding housing 2, the first clip 41 can also be directly connected to the flexible display panel 6.

[0063] The flexible support plate 7 matches the shape and size of the flexible display panel 6. The flexible support plate 7 and the flexible display panel 6 can be fixed together. When the sliding shell 2 slides in the direction away from the fixed shell 1, the flexible support plate 7 slides relative to the connecting arm 22, so that the two free ends of the flexible support plate 7 move away from each other, thereby driving part of the flexible display panel 6 to slide from the non-display surface to the display surface, thereby increasing the display area of ​​the sliding display device.

[0064] When the sliding shell 2 is manually pushed to slide toward the fixed shell 1, when the sliding shell 2 slides toward the fixed shell 1, the flexible support plate 7 slides relative to the connecting arm 22, so that the two free ends of the flexible support plate 7 approach each other, thereby driving part of the flexible display panel 6 to slide from the display surface to the non-display surface, so that the display area of ​​the sliding display device is reduced.

[0065] It should be noted that, in addition to the display panel, the flexible display device also includes other necessary components and elements, such as a circuit board and power cord. Those skilled in the art will be able to supplement these components based on the specific usage requirements of the display device, and these will not be detailed here. The scrolling display device can be a traditional electronic device, such as a mobile phone, computer, television, or camcorder, or it can be an emerging wearable device, such as a virtual reality device or augmented reality device, which are not listed here.

[0066] In order to ensure that the folding link assembly 5 is unfolded along the first direction, the sliding display device also includes a guide rail 14 arranged along the first direction. The guide rail 14 is arranged along the first direction. The guide rail 14 can be fixedly connected to the fixed shell 1. The sliding shell 2 is provided with a slider corresponding to the guide rail 14. The slider is fixedly connected to the sliding shell 2. The slider is slidably connected to the guide rail 14, thereby limiting the sliding direction of the connecting plate 23 relative to the fixed shell 1, and then determining the sliding trajectory of the middle part of the flexible display panel, so that the flexible display panel is always in a flat state during the unfolding process.

[0067] As shown in FIG11 and FIG12 , the working process of the scrolling display device is described in detail herein in conjunction with the specific structure of the scrolling display device shown in FIG1 to FIG10 .

[0068] The sliding housing 2 is manually pushed to move along the first direction toward the fixed housing 1, and the angle between the two adjacent links 51 in the folding link assembly 5 gradually decreases, and the torsion spring 52 gradually tightens. At the same time, the distance between the sliding housing 2 and the fixed housing 1 becomes smaller and smaller. When the connecting plate 23 contacts the spring seat 34, the first elastic member 33 is compressed, and the spring seat 34 slides along the inner wall of the fixed housing 1. The first inclined surface 415 of the first clip 41 slides along the second inclined surface 426 of the second clip 42. When the spring seat 34 moves to contact the bottom of the mounting seat 31, the first clip 41 slides into the second slot 424 of the second clip 42. The display area of ​​the flexible display panel gradually shrinks, and the sliding display device changes from an unfolded state to a tightened state.

[0069] When the protrusion 461 on the second stop block 46 is pressed, the push rod 43 pushes the first clip 41 to rotate along the pin shaft 47, so that the first clip 41 disengages from the second clip groove 424 of the second clip 42, and the connecting plate 23 is separated from the spring seat 34. At this time, the first elastic member 33 begins to relax. When the first elastic member 33 pushes the spring seat 34 to move along the first direction away from the fixed housing 1, the angle between the two adjacent connecting rods 51 gradually increases, so that the torsion spring 52 gradually relaxes. When the stop portion 341 of the spring seat 34 abuts against the mounting seat 31, the torsion spring 52 continues to relax, so that the angle between the two adjacent connecting rods 51 continues to increase, pushing the sliding housing 2 to continue to move in the direction away from the fixed housing 1, and the sliding display device changes from a tightened state to an unfolded state.

[0070] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
