Description

Technical Field

[0001] This utility model relates to the field of foldable mobile phone screen technology, specifically to a foldable mobile phone display structure based on flexible OLED. Background Technology

[0002] Foldable screens are a branch of flexible screens, capable of bending and even twisting 360 degrees. A foldable screen needs to withstand 200,000 folds without damage, making it a highly demanding type of flexible screen, and its structure requires a custom design.

[0003] In the prior art, patent CN217445388U discloses a crease-free bending hinge for a flexible screen folding phone, including a base. The base has symmetrically distributed rotating units that allow synchronous rotation within a 0-180 degree range. Each rotating unit includes a main control moving block, a secondary control moving block, and a cam connecting plate symmetrically distributed on both sides of the base and linked to the base. The main and secondary control moving blocks are linked to control the length of the rotation trajectory. The main control moving block and the cam connecting plate form a dual-track linkage shape control mechanism. The cam connecting plate is linked to the main control moving block. The cam connecting plate has a strip hole and a sliding shaft. The main control moving block has a curved groove and a shaft hole. A sliding shaft is installed in the shaft hole and slides in the strip hole, allowing the sliding shaft to slide within the curved groove to achieve dual-track rotation.

[0004] The above technical solution uses the concave-convex structure of the concave wheel connecting plate and the cam connecting plate to achieve the bending and locking of the display screen. This causes a jerky feeling when using the phone, which means that the phone needs to be bent at a specified angle during the folding process to ensure the stability of the phone screen. It cannot independently select the bending angle as needed, resulting in insufficient smoothness and affecting the user experience of the phone. Utility Model Content

[0005] The purpose of this invention is to provide a foldable mobile phone display structure based on flexible OLED.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-5 The illustrated foldable mobile phone display structure based on flexible OLED includes:

[0028] Main structure;

[0029] The main structure includes a folding screen 1, with backlight panel assemblies 2 on both sides of the bottom of the folding screen 1, and a hinge structure 3 between the backlight panel assemblies 2. The two sides of the hinge structure 3 are respectively connected to the backlight panel assemblies 2.

[0030] The hinge structure 3 includes a fixed base 31 and a movable top cover 32 that are interlocked. The interior of the fixed base 31 is rotatably connected to two sets of folding rotating shafts 33 via bearings. The two ends of the rotating shafts 33 extend to the outside of the fixed base 31 and are fixed with mounting seats 34 that are connected to the backlight panel assembly 2. A support seat 35 is fixed inside the fixed base 31. Storage slots 4 are provided at both ends of the support seat 35. A movable damping element 36 is movably arranged in the inner cavity of the storage slot 4. A fixed damping element 37 is fixed on the outside of the rotating shaft 33. The movable damping elements 36 fit together. A compression spring 38 is fixed inside the storage slot 4. One end of the compression spring 38 is fixed to one side of the movable damping element 36.

[0031] By installing a fixed damping component 37 and a movable damping component 36 on the rotating shaft 33 and the support base 35 respectively, and by utilizing the movable damping component 36 being supported and attached to the fixed damping component 37 by the compression spring 38, the two sets of rotating shafts 33 and fixed base 31 are limited and supported by friction, so as to ensure that the backlight panel assembly 2 remains stable after the folding screen 1 is folded. At the same time, the compression spring 38 can push the movable damping component 36 outward to avoid wear between the fixed damping component 37 and the movable damping component 36, which would reduce stability.

[0032] Among them, such as Figure 2-3 As shown:

[0033] An adjusting gear 5 is fixed on the outside of the rotating shaft 33. The opposing sides of the adjusting gear 5 mesh with each other. Through the cooperation of the adjusting gear 5, the two sets of rotating shafts 33 can rotate synchronously relative to the fixed base 31, ensuring that the two sets of backlight panel assemblies 2 are folded at the same angle relative to the hinge structure 3.

[0034] Furthermore, such as Figure 3-4 As shown:

[0035] The top of the support base 35 is provided with a sliding groove 6, and a slider 7 is slidably connected to the inner cavity of the sliding groove 6. The slider 7 is fixed to the outside of the movable damping member 36. The movable damping member 36 is connected to the slider 7, which restricts the rotation of the movable damping member 36 in the receiving groove 4 and affects the relative stability between the movable damping member 36 and the fixed damping member 37.

[0036] Preferred, such as Figure 4 As shown:

[0037] The top of the slider 7 has a countersunk hole, and a first mounting screw 8 is movably installed in the countersunk hole. The first mounting screw 8 passes through the slider 7 and is threadedly connected to the movable damping component 36. With the cooperation of the first mounting screw 8, the slider 7 and the movable damping component 36 can be detachably connected, making it convenient to replace the movable damping component 36.

[0038] It is worth noting that, such as Figure 2-4 As shown:

[0039] The fixed base 31 has a fixed limiting seat 9 inside. A limiting groove 10 is opened on the opposite side of the limiting seat 9. A limiting post 11 is fixed on the side of the fixed damping member 37 away from the movable damping member 36. The end of the limiting post 11 away from the fixed damping member 37 extends into the limiting groove 10. The limiting post 11 slides in the limiting groove 10 to limit the deflection angle of the rotating shaft 33 and prevent the folding screen 1 from bending in the opposite direction.

[0040] In a further preferred embodiment, such as Figure 2 As shown:

[0041] The fixed base 31 has two fixed slots 12 on its top sides, and the movable top cover 32 has slots 13 corresponding to the slots 12. The fixed base 31 and the movable top cover 32 can be easily locked together by the cooperation of the slots 12 and the slots 13.

[0042] In addition, such as Figure 1 As shown:

[0043] The bottom of the mounting base 34 is provided with a second mounting screw 14. The second mounting screw 14 passes through the mounting base 34 and is threadedly connected to the bottom of the backlight panel assembly 2. The second mounting screw 14 facilitates the connection between the hinge structure 3 and the backlight panel assembly 2 through the mounting base 34.

[0044] In this embodiment, as Figure 1 As shown:

[0045] The foldable area is located in the middle of the foldable screen 1 and is located on the outside of the hinge structure 3. By setting the foldable area, the foldable screen 1 can be folded at the hinge structure 3. Other areas can be connected to the backlight panel assembly 2 to maintain the stability of the structure.

[0046] In practical use, the mounting base 34 is connected to the hinge structure 3 and the backlight panel assembly 2 via the second mounting screw 14. When the foldable screen 1 is folded for use, the two sets of backlight panel assemblies 2 drive the mounting base 34 to rotate the rotating shaft 33. Under the restriction of the adjusting gear 5, the two sets of rotating shafts 33 rotate at the same angle relative to the fixed base 31. The fixed damping member 37 on the outside of the rotating shaft 33 rotates under the friction of the movable damping member 36. At the same time, the compression spring 38 provides the squeezing force between the movable damping member 36 and the fixed damping member 37. The bendable area of ​​the foldable screen 1 bends on the outside of the hinge structure 3.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
