Description

Technical Field

[0001] This invention relates to the field of display product manufacturing technology, and in particular to a sliding roll support structure and a sliding roll device. Background Technology

[0002] Currently, flexible screens are being used in more and more scenarios. Based on user needs and technological development, flexible screens are also taking on more and more bending forms, gradually developing into forms such as folding, sliding, or rolling.

[0003] To accommodate the transition between the unfolded and bent states of a flexible screen, forces are typically applied to the screen through the interaction of supporting structures. However, in the unfolded state, there are gaps in the supporting structures, resulting in insufficient support. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a sliding roll support structure and a sliding roll device, solving the problem of insufficient support for flexible display modules in the unfolded state.

[0005] To achieve the above objectives, the technical solution adopted in this embodiment of the invention is: a sliding roll device support structure for supporting a flexible display module, comprising:

[0006] The first support component includes a first comb structure extending along the unfolding direction of the flexible display module. The first comb structure includes a plurality of first comb teeth and a plurality of first gaps arranged in an alternating manner.

[0007] In the unfolding direction of the flexible display module, the first support component and the second support component move in opposite directions or towards each other to allow the support structure to switch between a tightened state and an unfolded state. The second support component includes a second comb tooth structure extending along the unfolding direction of the flexible display module. The first comb tooth structure and the second comb tooth structure mesh with each other. The second comb tooth structure includes a plurality of second comb teeth and a plurality of second gaps arranged in an alternating manner.

[0008] Multiple rotating wheels are disposed within at least a portion of the second gap;

[0009] Multiple flexible support strips are arranged one-to-one with multiple rotating wheels. The first end of each flexible support strip is fixedly connected to the corresponding first comb tooth, and the second end of each flexible support strip is fixed to the corresponding rotating wheel. In the tightened state, the flexible support strip is wound around the corresponding rotating wheel. When the state changes from tightened to unfolded, the flexible support strip, the first comb tooth, and the second comb tooth jointly support the flexible display module.

[0010] Optionally, a plurality of the rotating wheels are disposed within a portion of the second gap, and the plurality of rotating wheels are equally spaced in a direction perpendicular to the extending direction of the second gap.

[0011] Optionally, the number of the plurality of said rollers is the same as the number of the plurality of second gaps.

[0012] Optionally, the end face of the first end of the flexible support strip is fixedly connected to the end face of the third end opposite to the first comb tooth and the second comb tooth.

[0013] Optionally, the flexible support strip has a first support surface, the first comb tooth has a second support surface, and at the first end, the first support surface and the second support surface are flush.

[0014] Optionally, a baffle is provided in the second gap, which divides the second gap into a first region and a second region in the extending direction of the second gap. The first region is located away from the first comb teeth, and the rotating wheel is located in the first region.

[0015] Optionally, a first connecting shaft is provided on each side of the rotating wheel in the axial direction, and the first connecting shaft is rotatably connected to the connecting hole of the corresponding second comb tooth.

[0016] Optionally, it also includes a sliding wheel, which is connected to the rotating wheel and slides in contact with the flexible display module.

[0017] Optionally, the diameter of the rotating wheel is smaller than the diameter of the sliding wheel.

[0018] This invention also provides a roll-up device, a flexible display module, and the aforementioned roll-up device support structure for supporting the flexible display module.

[0019] The beneficial effect of the present invention is that by setting the rotating wheel and the flexible support strip, the support performance of the support structure can be enhanced in the unfolded state, and wrinkles can be avoided in the flexible display module.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] refer to Figures 1-6 This embodiment provides a sliding device support structure for supporting a flexible display module 10, including:

[0029] The first support component 1 includes components along the unfolding direction of the flexible display module 10 (see reference). Figure 5 A first comb structure 11 extending in the X direction is provided, the first comb structure 11 including a plurality of first comb teeth 101 and a plurality of first gaps 102 arranged in an alternating manner;

[0030] In the unfolding direction of the flexible display module 10, the first support component 1 and the second support component 2 move in opposite directions or towards each other so that the support structure can switch between a tightened state and an unfolded state. The second support component 2 includes a second comb structure 21 extending along the unfolding direction of the flexible display module 10. The first comb structure 11 and the second comb structure 21 mesh with each other. The second comb structure 21 includes a plurality of second comb teeth 201 and a plurality of second gaps 202 arranged in an alternating manner.

[0031] Multiple rotating wheels 22 are disposed within at least a portion of the second gap 202;

[0032] Multiple flexible support bars 23 are arranged one-to-one with multiple rotating wheels 22. The first end of each flexible support bar 23 is fixedly connected to the corresponding first comb tooth 101, and the second end of each flexible support bar 23 is fixed to the corresponding rotating wheel 22. In the tightened state, the flexible support bar 23 is wound around the corresponding rotating wheel 22. When the state changes from tightened to unfolded, the flexible support bar 23, the first comb tooth 101, and the second comb tooth 201 jointly support the flexible display module 10.

[0033] Both the first comb tooth 101 and the second comb tooth 201 have a support surface. The support surface of the first comb tooth 101 is flush with the support surface of the second comb tooth 201, meaning that the support surfaces of the first comb tooth 101 and the second comb tooth 201 are on the same horizontal plane. This arrangement ensures that, as the first support component 1 and the second support component 2 move closer or further apart, the plane formed by the support surfaces of the first comb tooth 101 and the second comb tooth 201 consistently provides support to the flexible display module 10.

[0034] The support structure is in the tightened state, meaning the first comb teeth 101 and the second comb teeth 201 intersect each other and are in close contact with each other. Multiple first gaps 102 are filled by multiple second comb teeth 201, and multiple second gaps 202 are filled by multiple first comb teeth 101. At this time, the flexible display module 10 is in the tightened state, and the first comb tooth structure 11 and the second comb tooth structure 21 mesh with each other, making the upper surface of the support device (i.e., the support surface for contacting the back support of the flexible display module 10) a complete plane. In this way, support force can be provided to the entire back of the display portion of the flexible display module 10.

[0035] When the support structure transitions from a tightened state to an unfolded state, the first comb tooth structure 11 and the second comb tooth structure 21 move away from each other, and the first comb tooth 101 and the second comb tooth 201 move away from each other, thereby increasing the area of ​​the support surface of the support device. This allows for the provision of support force to the entire back of the increasingly larger display portion of the flexible display module 10 in the unfolded state. However, precisely because of this, the intersection between the first comb tooth 101 and the second comb tooth 201 decreases, and the first comb tooth 101 and the second comb tooth 201 become increasingly separated from each other. As the space filled by the second comb teeth 201 in the first gap 102 decreases, so does the space filled by the first comb teeth 101 in the second gap 202. When the support structure is fully converted to the unfolded state, the space filled by the first comb teeth 101 in the second gap 202 is minimal. Therefore, at the positions corresponding to the first gap 102 or the second gap 202, the area supported by the flexible display module 10 decreases, thereby reducing the support performance of the support structure. This makes it easy for wrinkles to appear in the positions corresponding to the first gap 102 or the second gap 202. In other words, by simply using the first comb tooth structure 11 and the second comb tooth structure 21 to support the display panel, in the unfolded state, the presence of the first gap 102 and the second gap 202 makes it impossible to achieve full-surface support. If full-surface support were achieved, the first comb tooth structure 11 and the second comb tooth structure 21 would interfere with each other, and it might even be impossible to switch between the tightened and unfolded states by sliding.

[0036] In this embodiment, the rotating wheel 22 and the flexible support strip 23 allow the second gap 202 to be filled by the flexible support strip 23 when the support structure transitions from the tightened state to the unfolded state, thereby enhancing the support performance of the support structure and preventing wrinkles from appearing in the flexible display module 10. The addition of the rotating wheel 22 and the flexible support strip 23, and the cooperation between the flexible support strip 23 and the first and second comb teeth, achieves full-area support for the display panel in the unfolded state without affecting the transition of the support structure between the tightened and unfolded states via a sliding motion.

[0037] It should be noted that the display surface of the flexible display module 10 is the front, and the side opposite the front is the back. In this embodiment, the first support component 1 and the second support component 2 are configured to move closer to or further away from each other, allowing the support structure to be tightened or expanded. The movement of the first support component 1 and the second support component 2 closer to or further away from each other can be manually driven by the user. For example, the user can apply force to the support structure by pulling or pushing to bring the first support component 1 and the second support component 2 closer together or to move them further apart. Alternatively, a driving component can be provided to automatically separate the first support component 1 and the second support component 2 or automatically pull them closer together.

[0038] It should be noted that the driving component can be any of the following structures: piston, gear rack, cam slider, or other driving structure, as long as it can apply force to the first support component 1 and the second support component 2 so that the first support component 1 and the second support component 2 are relatively close or relatively far apart.

[0039] In some embodiments, the flexible display module 10 includes a fixed display portion and a rollable portion (in the tightened state, the rollable portion rolls into the interior of a rolling device; in the unfolded state, the rollable portion unfolds for display). The first support member 1 is fixed, and the second support member 2 is movable relative to the first support member 1. The first support member 1 includes a first comb structure 11 and a rigid portion located on one side of the first comb structure 11 in the unfolding direction of the flexible display module 10. The rigid portion is located on the side of the first comb structure 11 away from the second comb structure 21. The flexible section is used to support the fixed display portion of the flexible display module 10. The rollable portion can be divided into a first portion supported by the first comb structure 11 and a second portion supported by the second comb structure 21. Since the second portion is farther away from the fixed display portion, the problem of insufficient support performance of the support structure mainly occurs in the second comb structure 21. In some embodiments, in order to address the problem of insufficient support performance of the second comb structure 21, the rotating wheel 22 and the flexible support strip 23 are provided in the second gap portion 202, which can improve the problem of insufficient support performance of the support structure in the unfolded state.

[0040] For example, in order to effectively improve the support performance of the support structure, at least a portion of the first gap 102 is provided with a plurality of the same rotating wheels 22 and a flexible support strip 23 corresponding to each of the plurality of rotating wheels 22. One end of the flexible support strip 23 is fixed to the second comb tooth 201, and the other end of the flexible support strip 23 is wound around the rotating wheel 22. That is, both the first gap 102 and the second gap 202 are provided with a plurality of the rotating wheels 22 and the flexible support strip 23. When the support structure is converted from a tightened state to an unfolded state, the rotating wheels 22 and the flexible support strip 23 located in the first gap 102 fill the first gap 102, and the rotating wheels 22 and the flexible support strip 23 located in the second gap 202 fill the second gap 202.

[0041] In a direction perpendicular to the extending direction of the first comb tooth 101 (refer to...) Figure 5 In the Y direction, the widths of the first comb tooth 101 and the second comb tooth 201 are the same, but the presence of the first gap 102 also reduces the support performance of the support structure. In this case, in order to enhance the support performance of the first support member 1, the width of the first comb tooth 101 is increased and the width of the second comb tooth 201 is decreased. That is, the sum of the widths of the first comb tooth 101 and the second comb tooth 201 remains unchanged, and the ratio of the width of the first comb tooth 101 to the width of the second comb tooth 201 is changed (for example, the ratio of the width of the first comb tooth 101 to the width of the second comb tooth 201 is changed to 10:4). This reduces the width of the first gap 102 and improves the support performance of the first support member 1. As for the second support member 2, the width of the second gap 202 is increased. The support performance of the second support member 2 can be improved by setting the rotating wheel 22 and the flexible support strip 23, thereby improving the overall support performance of the support structure.

[0042] The specific structure of the rotating wheel 22 and the flexible support bar 23 located in the second gap 202 will be described in detail below.

[0043] The flexible support strip 23 is made of metal sheet, such as steel sheet. In the unfolded state, the flexible support strip 23 needs to maintain a flat state. In the tightened state, the flexible support strip 23 is wound around the rotating wheel 22, similar to a measuring tape. This ensures its support performance and makes it easy to store and wind up, and facilitates the transition between the tightened and unfolded states.

[0044] For example, the thickness of the flexible support strip 23 can be 0.1-0.15 mm, but is not limited to this. Choosing a thinner thickness for the flexible support strip 23 can reduce the thickness of the flexible support strip 23 in the radial direction of the rotating wheel 22 after it is wound around the rotating wheel 22 in the tightened state, thereby reducing the step difference.

[0045] For example, a plurality of the rotating wheels 22 are disposed within a portion of the second gap 202, and the plurality of rotating wheels 22 are equally spaced in a direction perpendicular to the extending direction of the second gap 202. A plurality of flexible support bars 23 are disposed in a one-to-one correspondence with the plurality of rotating wheels 22. When the number of rotating wheels 22 is less than the number of second gaps 202, the plurality of rotating wheels 22 are equally spaced, that is, the plurality of flexible support bars 23 are equally spaced, which facilitates the uniformity of support in the support structure.

[0046] For example, the number of the plurality of rollers 22 is the same as the number of the plurality of second gaps 202. That is, each second gap 202 is provided with one roller 22, which more effectively improves the support performance of the support structure.

[0047] For example, the end face of the first end of the flexible support strip 23 is fixedly connected to the end face of the third end opposite to the first comb tooth 101 and the second comb tooth 201. The connection between the flexible support strip 23 and the comb tooth can be welding, snap-fitting, etc.

[0048] For example, the flexible support strip 23 has a first support surface, and the first comb tooth 101 has a second support surface. At the first end, the first support surface and the second support surface are flush. This avoids step differences that could affect the flatness of the flexible display module 10.

[0049] For example, a baffle 25 is provided within the second gap 202, dividing the second gap 202 into a first region and a second region along its extension direction. The first region is located away from the first comb teeth 101, and the rotating wheel 22 is disposed within the first region. The baffle 25 prevents interference between the first support member 1 and the rotating wheel 22, thus protecting the flexible support strip 23.

[0050] For example, connecting shafts 221 are respectively provided on both sides of the rotating wheel 22 in the axial direction. The connecting shafts 221 are rotatably connected to the connecting holes 222 of the corresponding second comb teeth 201. (Refer to...) Figure 2 .

[0051] Multiple rotating wheels 22 can be independently arranged in the corresponding second gap 202, or multiple rotating wheels 22 can share a connecting shaft 221. For ease of installation, in this embodiment, it is preferred that multiple rotating wheels 22 can be independently arranged in the corresponding second gap 202.

[0052] The rotating wheel 22 and the connecting shaft 221 can rotate synchronously, that is, the connecting shaft 221 can rotate within the corresponding connecting hole 222. The rotating wheel 22 can also rotate relative to the connecting shaft 221, that is, the connecting shaft 221 is fixedly connected to the corresponding connecting hole 222, the rotating wheel 22 is sleeved on the connecting shaft 221, and can rotate around the connecting shaft 221.

[0053] For example, two adjacent rotating wheels 22 are a first rotating wheel and a second rotating wheel. The second comb tooth 201 between the two adjacent rotating wheels 22 has a connecting hole 222 that connects to the first rotating wheel and the second rotating wheel. The connecting hole 222 includes a first connecting hole that connects to the first rotating wheel and a second connecting hole that connects to the second rotating wheel. The first connecting hole and the second connecting hole can be connected.

[0054] For example, the support structure further includes a sliding wheel 24, which is kinetically connected to the rotating wheel 22 and slides in contact with the flexible display module 10. The sliding wheel 24 slides under the drive of the rotating wheel 22 and experiences sliding friction with the flexible display module 10, reducing friction and assisting in the rolling process of the flexible display module 10. Figure 3 This is a schematic diagram of the assembly state of the sliding wheel 24 and the flexible display module 10.

[0055] In the unfolded state, the flexible support strip 23, together with the first comb tooth 101 and the second comb tooth 201, supports the flexible display module 10 and has a certain length. Therefore, in the tightened state, the flexible support strip 23 is wound around the rotating wheel 22 and has a certain thickness (thickness in the radial direction of the rotating wheel 22). To avoid a height difference between the rotating wheel 22 and the first comb tooth 101 or the second comb tooth 201 in the tightened state, causing a bulge at the corresponding position of the flexible display module 10, in some embodiments of this example, the diameter of the rotating wheel 22 is smaller than the diameter of the sliding wheel 24. (Refer to...) Figure 3 .

[0056] For example, in the tightened state, the flexible support strip 23 wound around the rotating wheel 22 just comes into contact with the flexible display module 10, but is not limited thereto.

[0057] This invention also provides a roll-up device, a flexible display module 10, and the aforementioned roll-up device support structure for supporting the flexible display module 10.

[0058] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
