Description

Technical Field

[0001] This application relates to the technical field of flexible connection structures, and more particularly to a flexible connection structure for a foldable display. Background Technology

[0002] A display is a device that converts electronic data into images for display, and with the increasing functionality of displays, and the development of flexible screens, there is a growing variety of foldable displays.

[0003] In the prior art, there is a foldable flexible display consisting of a central part and left and right side parts. The left and right side parts can be flipped down or up along the central part from the plane. In the normal state, the left and right side parts are flipped down, and the device as a whole is in a triangular shape.

[0004] However, during the long-term repeated folding process, permanent creases are easily formed on the screen surface of the monitor. At the same time, the flexible connection structure is prone to fatigue fracture due to long-term bending. In addition, the traditional hinge structure is complex and increases the thickness of the device. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, one objective of this application is to provide a flexible connection structure for a foldable display. By dynamically dispersing stress, the screen bending area is subjected to uniform force, and a substrate layer and an elastic support layer are bonded below the screen folding area. When folded, the silicone of the wave-shaped structure of the elastic support layer is compressed, absorbing more than 80% of the stress. The metal mesh of the limiting layer prevents the bending radius from being less than 3mm, avoiding screen damage and preventing excessive bending. When the display is unfolded, the elastic support layer rebounds to restore the screen to a flat state. At the same time, the overall structural thickness is ≤0.5mm, making it suitable for thin and light devices.

[0007] To achieve the above objectives, the first aspect of this application provides a flexible connection structure for a foldable display, including a rigid member, within which a flexible connection device for connecting the foldable display is disposed; the flexible connection device includes a connecting component disposed within the rigid member for rotation, and a flexible support component for protection is disposed at the top end of the connecting component.

[0008] In addition, the flexible connection structure of the foldable display proposed in this application may also have the following additional technical features:

[0009] In one embodiment of this application, a fixing block for assisting the connecting assembly in folding is fixedly installed on the rigid member, and there are four fixing blocks.

[0010] In one embodiment of this application, a connecting block for movably connecting with a connecting component is fixedly installed on the top of the rigid member, and there are two connecting blocks, which are symmetrically distributed on the top of the rigid member.

[0011] In one embodiment of this application, the connecting component includes a pair of hinge blocks movably connected to the connecting block, and the top ends of the pair of hinge blocks are jointly fixedly mounted with a mounting block for connection to a flexible support component.

[0012] In one embodiment of this application, a rotating shaft for driving the hinge block to rotate is provided on the front side of the connecting block, a gear one is provided on the shaft body of the rotating shaft, and a transmission shaft for rotating is provided at the front end of the connecting block, a gear two for meshing with the gear one is provided on the shaft body of the transmission shaft.

[0013] In one embodiment of this application, the flexible support assembly includes a substrate layer fixedly mounted on the top of the mounting block, and a limiting layer for limiting the position of the display screen is fixedly mounted on the top of the substrate layer.

[0014] In one embodiment of this application, the top of the limiting layer is provided with an elastic support layer for buffering the pressure of the display screen. The elastic support layer is inlaid with a plurality of silicone for buffering. A protective layer for protection is fixedly installed on the top of the elastic support layer.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] By incorporating connecting components and flexible support components, stress is dynamically dispersed, ensuring uniform force distribution in the screen's bending area. A substrate layer and an elastic support layer are bonded beneath the folding area. During folding, the wavy silicone structure of the elastic support layer is compressed, absorbing over 80% of the stress. The metal mesh of the limiting layer prevents the bending radius from exceeding 3mm, avoiding screen damage and preventing excessive bending. When the display unfolds, the elastic support layer rebounds, restoring the screen to its flat state. Simultaneously, the overall structural thickness is ≤0.5mm, making it suitable for thin and light devices.

[0025] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0026] The following description, in conjunction with the accompanying drawings, describes a flexible connection structure for a foldable display according to an embodiment of this application.

[0027] like Figures 1-5 As shown, a flexible connection structure for a foldable display according to an embodiment of this application may include a rigid member 100, and a flexible connection device 200 for connecting the foldable display is disposed within the rigid member 100; the flexible connection device 200 includes a connecting component 210 for rotation disposed within the rigid member 100, and a flexible support component 220 for protection is disposed at the top end of the connecting component 210.

[0028] In one embodiment of this application, such as Figure 2As shown, a fixing block 101 for assisting the connecting assembly 210 in folding is fixedly installed on the rigid member 100, and there are four fixing blocks 101, which are fixed at the upper and lower ends of the rigid member 100; a connecting block 102 for movably connecting with the connecting assembly 210 is fixedly installed on the top end of the rigid member 100, and there are two connecting blocks 102, which are symmetrically distributed at the top end of the rigid member 100.

[0029] In one embodiment of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, there are two connecting components 210. The two connecting components 210 are symmetrically connected to the connecting block 102, thus assisting the display in folding and rotating. The connecting component 210 includes a pair of hinge blocks 211 that are movably connected to the connecting block 102. The top ends of the pair of hinge blocks 211 are fixedly mounted with a mounting block 212 for connecting to the flexible support component 220.

[0030] Furthermore, the front side of the connecting block 102 is provided with a rotating shaft 213 for driving the hinge block 211 to rotate, and the rotating shaft 213 passes through the connecting block 102 and is fixedly connected to the hinge block 211. Therefore, when the display is folded and rotated, the rotating shaft 213 can be driven to rotate around the connecting block 102, and at the same time, the hinge block 211 can control the flexible support component 220 on the mounting block 212 to fold.

[0031] Furthermore, a gear 214 is provided on the shaft of the rotating shaft 213, and the gear 214 is located on the front side of the connecting block 102; a drive shaft 215 for rotation is provided at the front end of the connecting block 102, wherein the front end of the drive shaft 215 is movably connected to the fixed block 101, and the rear end of the drive shaft 215 is movably connected to the connecting block 102; a gear 216 for meshing with the gear 214 is provided on the shaft of the drive shaft 215; thus, when it is necessary to drive the display to fold, the two hinge blocks 211 hinge and rotate around the connecting block 102, and under the meshing connection between the gear 214 and the gear 216, the display on the flexible support assembly 220 can be controlled to fold.

[0032] In one embodiment of this application, such as Figure 2 , Figure 3 and Figure 5As shown, the overall thickness of the flexible support component 220 is ≤0.5mm. The flexible support component 220 includes a substrate layer 225 fixedly installed on the top of the mounting block 212. The substrate layer 225 is made of a highly elastic polymer material such as polyimide as the supporting substrate of the screen. A limiting layer 224 for limiting the display screen is fixedly installed on the top of the substrate layer 225. The limiting layer 224 is embedded in a flexible metal mesh in the substrate layer 225 to limit excessive bending. At the same time, the limiting layer 224 is made of shape memory alloy and automatically returns to a flat state when heated.

[0033] Furthermore, the top of the limiting layer 224 is provided with an elastic support layer 222 for buffering the pressure on the display screen. The elastic support layer 222 is inlaid with a number of silicone 223 for buffering. A protective layer 221 for protection is fixedly installed on the top of the elastic support layer 222. The protective layer 221 is used to cover the outermost wear-resistant coating to reduce surface friction damage. When the display needs to be compressed or unfolded, the substrate layer 225 and the elastic support layer 222 are attached below the screen folding area. When folding, the wavy silicone 223 of the elastic support layer 222 is compressed, absorbing more than 80% of the stress. The metal mesh of the limiting layer 224 prevents the bending radius from being less than 3mm, avoiding screen damage. After the display is unfolded, the elastic support layer 222 rebounds to restore the screen to flatness.

[0034] In summary, the flexible connection structure of the foldable display according to the embodiments of this application allows the pivot 213 to rotate around the connecting block 102 when the display is folded and rotated, while the hinge block 211 controls the flexible support component 220 on the mounting block 212 to fold; the substrate layer 225 and the elastic support layer 222 are bonded below the folding area of ​​the screen; when folding, the wavy silicone 223 of the elastic support layer 222 is compressed, absorbing more than 80% of the stress; the metal mesh of the limiting layer 224 prevents the bending radius from being less than 3mm, avoiding screen damage; and after the display is unfolded, the elastic support layer 222 rebounds to restore the screen to flatness.
