Description

Technical Field

[0001] This utility model relates to the field of flexible LCM display module technology, specifically a bendable flexible LCM display module support frame. Background Technology

[0002] With the rapid development of flexible display technology, bendable and foldable LCM display modules are increasingly widely used in consumer electronics, automotive electronics and other fields. The core requirement for these modules is to ensure stable display performance while achieving multiple bends (bending radius as small as 5mm). As a key structural component of the module, the performance of the support frame directly affects the bending reliability and service life of the module.

[0003] The support frame of existing flexible LCM display modules mostly uses a single metal sheet. Although it has high strength, it lacks flexibility and is prone to cracking or even breaking after long-term repeated bending.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a flexible LCM display module support frame. Utility Model Content

[0005] The purpose of this invention is to provide a flexible LCM display module support frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible LCM display module support frame, including a support component and an arc-shaped cutout. The support component includes a titanium-nickel shape memory alloy sheet, through holes, an elastic buffer layer one, an elastic buffer layer two, and grooves. The surface of the titanium-nickel shape memory alloy sheet has through holes. The upper surface of the titanium-nickel shape memory alloy sheet is laminated with the elastic buffer layer one through a molding process, and the lower surface of the titanium-nickel shape memory alloy sheet is laminated with the elastic buffer layer two through a molding process. Grooves are provided on the side of the elastic buffer layer one and the elastic buffer layer two away from the titanium-nickel shape memory alloy sheet. The arc-shaped cutout is located at the central axis of the support component, and a flexible connecting rib is bonded to the inner side of the arc-shaped cutout with high-temperature resistant adhesive. An adhesive layer one is provided on the upper surface of the elastic buffer layer one.

[0007] Furthermore, the thickness of the titanium-nickel shape memory alloy sheet is 0.2 mm, the diameter of the through hole is 0.5 mm, and the distance between two adjacent through holes is 3 mm.

[0008] Furthermore, the first elastic buffer layer and the second elastic buffer layer are made of epoxy resin, and the thickness of the first elastic buffer layer and the second elastic buffer layer is 0.1 mm.

[0009] Furthermore, the groove is mesh-like, and the depth of the groove is 0.035 mm.

[0010] Furthermore, a stainless steel strip is fixed to the edge of the titanium-nickel shape memory alloy sheet, and the edge of the stainless steel strip is rounded.

[0011] Furthermore, the arc-shaped cuts are equidistantly distributed along the bottom of the support assembly, and the distance between two adjacent arc-shaped cuts is 1 mm.

[0012] Furthermore, the titanium-nickel shape memory alloy sheet and the stainless steel strip are fixedly connected, and two stainless steel strips are provided.

[0013] This utility model provides a flexible LCM display module support frame, which has the following advantages:

[0014] 1. The arc-shaped cut of this utility model is located at the central axis of the support component. With the help of flexible connecting ribs, the support component can be bent precisely in a preset direction to avoid non-directional deformation. The titanium-nickel shape memory alloy sheet can withstand tens of thousands of repeated bends. The 0.2mm thickness balances the rigidity and flexibility of the support and has a service life far exceeding that of a single metal frame. Moreover, the stainless steel strip only covers the edge of the non-bending area of ​​the support component, which can achieve the edge protection function without adversely affecting the bending performance of the support component.

[0015] 2. When the titanium-nickel shape memory alloy sheet of this utility model is laminated with the first elastic buffer layer and the second elastic buffer layer through a molding process, some epoxy resin can be filled into the through holes to form a strong mechanical bond. At the same time, when the adhesive layer one on the upper surface of the first elastic buffer layer is bonded to the back of the flexible LCM display module, some adhesive material will enter the grid-like grooves, thereby increasing the contact area and friction, and enhancing the adhesive bonding force with the flexible LCM display module. The dual design effectively avoids peeling or sliding between the layers. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3 As shown, a flexible LCM display module support frame includes a support component 1 and an arc-shaped cutout 2. The arc-shaped cutout 2 is opened at the central axis of the support component 1, and a flexible connecting rib 4 is bonded to the inner side of the arc-shaped cutout 2 by high-temperature resistant adhesive 3. A stainless steel strip 5 is fixed to the edge of a titanium-nickel shape memory alloy sheet 101, and the edge of the stainless steel strip 5 is rounded. The arc-shaped cutouts 2 are evenly distributed along the bottom of the support component 1, and the distance between two adjacent arc-shaped cutouts 2 is 1mm. The titanium-nickel shape memory alloy sheet 101 and the stainless steel strip 5 are fixedly connected, and two stainless steel strips 5 are provided.

[0022] The specific operation is as follows: the arc-shaped cut 2 is located at the central axis of the support component 1. Together with the flexible connecting rib 4, it can enable the support component 1 to bend precisely in the preset direction, avoiding non-directional deformation. The titanium-nickel shape memory alloy sheet 101 can withstand tens of thousands of repeated bending. The 0.2mm thickness takes into account both the rigidity and flexibility of the support. Its service life is far longer than that of a single metal frame. Moreover, the stainless steel strip 5 only covers the edge of the non-bending area of ​​the support component 1. While achieving the edge protection function, it will not have an adverse effect on the bending performance of the support component 1.

[0023] like Figure 1 and Figure 3As shown, the support component 1 includes a titanium-nickel shape memory alloy sheet 101, a through hole 102, an elastic buffer layer one 103, an elastic buffer layer two 104, and a groove 105. The through hole 102 is formed on the surface of the titanium-nickel shape memory alloy sheet 101. The elastic buffer layer one 103 is laminated onto the upper surface of the titanium-nickel shape memory alloy sheet 101 by a molding process, and the elastic buffer layer two 104 is laminated onto the lower surface of the titanium-nickel shape memory alloy sheet 101 by a molding process. The elastic buffer layer one 103 and the elastic buffer layer two 104 are located away from the titanium-nickel shape memory alloy sheet 101. One side surface of 01 is provided with grooves 105. The thickness of the titanium-nickel shape memory alloy sheet 101 is 0.2mm. The diameter of the through hole 102 is 0.5mm. The distance between two adjacent through holes 102 is 3mm. The first elastic buffer layer 103 and the second elastic buffer layer 104 are made of epoxy resin. The thickness of the first elastic buffer layer 103 and the second elastic buffer layer 104 is 0.1mm. The grooves 105 are grid-shaped and the depth of the grooves 105 is 0.035mm. The upper surface of the first elastic buffer layer 103 is provided with an adhesive layer 6.

[0024] The specific operation is as follows: When the titanium-nickel shape memory alloy sheet 101 is laminated with the elastic buffer layer 103 and the elastic buffer layer 104 through a molding process, some epoxy resin can be filled into the through hole 102 to form a strong mechanical bond. At the same time, when the adhesive layer 6 on the upper surface of the elastic buffer layer 103 is bonded to the back of the flexible LCM display module, some adhesive material will enter the grid-like groove 105, thereby increasing the contact area and friction, and enhancing the adhesive bonding force with the flexible LCM display module. The dual design effectively avoids peeling or sliding between the layers.

[0025] In summary, when using the flexible LCM display module support frame, the back of the flexible LCM display module is first bonded to the surface of the elastic buffer layer 103 through the adhesive layer 6. Since the grid-like grooves 105 can accommodate some adhesive material, the bonding strength between the module and the support component 1 is significantly enhanced, effectively preventing relative displacement between the two. In addition, the through holes 102 evenly distributed on the surface of the titanium-nickel shape memory alloy sheet 101 can form a tight mechanical engagement with the elastic buffer layer 103 and the elastic buffer layer 2 104, further improving the stability of the interlayer connection.

[0026] When the flexible LCM display module is subjected to external force and needs to be bent, the support component 1 will undergo directional deformation along the arc-shaped cut 2 at the central axis. The arc-shaped cut 2 provides sufficient space for deformation. The 1mm spacing between adjacent arc-shaped cuts 2 can evenly distribute stress. The flexible connecting rib 4 on the inner side deforms synchronously with bending, ensuring that the titanium-nickel shape memory alloy sheet 101 separated by the arc-shaped cut 2 does not detach and always maintains structural continuity. At the same time, the titanium-nickel shape memory alloy sheet 101 achieves reversible bending due to its own superelastic properties. The elastic buffer layer 103 and the elastic buffer layer 104 absorb the stress generated by bending through their own elasticity, avoiding the stress from being directly transmitted to the interior of the LCM module and causing damage.

[0027] When the external force is removed, the titanium-nickel shape memory alloy sheet 101 automatically returns to its initial planar state due to the shape memory effect. The elastic buffer layer 103 and the elastic buffer layer 104 simultaneously and elastically reset. The flexible connecting rib 4, made of polyimide film with excellent flexibility and bending performance, guides the overall structure to smoothly recover, while the stainless steel strip 5 continuously maintains edge stability, ensuring that the flexible LCM display module is undamaged throughout the process.
