With the continuous advancement of technology and the continuous reduction of costs, flexible OLED display modules will have a broader market prospect and become one of the mainstream directions of future display technology development.

[0004] At present, flexible OLED display modules display images and content by controlling the light emission of organic light-emitting diodes. At the same time, due to the flexible design, more flexible and diverse display forms can be achieved. At present, flexible OLED display modules are mostly installed on the mounting base using magnets and spliced together with other display modules. However, the four corners may still be warped, and magnets alone cannot limit the restoration of the display module. Some display modules may be taped on the edges during installation, but this is difficult to clean. Secondly, the power interface will accumulate dust and cause poor contact if it is exposed to the outside for a long time. Therefore, a flexible OLED display module is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a flexible OLED display screen module, including a display screen main body 1, a shell 2 fixedly connected to the back of the display screen main body 1, the display screen main body 1 is a flexible OLED display screen module that can realize multiple forms such as curved, foldable, and bent, and the shell 2 is provided with multiple sets of grooves, which can be bent in conjunction with the display screen main body 1, and a mounting base 3 is detachably connected to the back of the shell 2. A magnet is embedded in the shell 2, which can be adsorbed on the iron block embedded in the mounting base 3. The inner wall of the mounting base 3 is rotatably connected to a rotating shaft 4, and the inner end of the rotating shaft 4 is fixedly connected to an elliptical block 9. An elliptical groove 10 is provided on the inner wall of the shell 2, and the outer wall of the elliptical block 9 is plugged into the inner wall of the elliptical groove 10. In the process of installing the shell 2 together with the display screen main body 1 on the mounting base 3, the elliptical block 9 passes through the elliptical groove 10, and at this time, it rotates to the rotating shaft 4 to drive the elliptical The circular block 9 rotates to buckle the inner wall of the shell 2, and the inner wall of the rotating shaft 4 is elastically connected to the pull rod 6 through the return spring a5. One end of the return spring a5 is fixedly connected to the inner wall of the rotating shaft 4, and the other end of the return spring a5 is fixedly connected to the inner end of the pull rod 6. Pulling the pull rod 6 outward can stretch the return spring a5 to move outward. At the same time, the tension generated by the deformation of the return spring a5 gives the pull rod 6 an inward pulling force, prompting it to reset. A buckle assembly is fixedly connected to the inner side of the pull rod 6, and the buckle assembly includes a clamping block 7. The back side of the clamping block 7 is fixedly connected to the inner side of the pull rod 6. Several groups of slots 8 are provided on the back side of the mounting base 3. The outer wall of the clamping block 7 is clamped with the inner wall of the clamping slot 8. Pulling the pull rod 6 outward can make the clamping block 7 be pulled out of the clamping slot 8. At this time, the pull rod 6 can be rotated to drive the rotating shaft 4 to rotate. The outer wall of the pull rod 6 is provided with a rectangular protrusion structure which is buckled into the inner wall groove of the rotating shaft 4, which can drive the rotating shaft 4 to rotate together.

[0032] Reference Figure 1 、 Figure 2 and Figure 4A power interface 12 is provided on the back of the display screen body 1, and a power board is provided on the inner wall of the mounting base 3 so that the wires can be inserted into the power interface 12. A protective shell 11 is fixedly connected to the back of the display screen body 1, and a protective plate 13 is slidably connected to the inner wall of the protective shell 11. A handle 14 is fixedly connected to the side wall of the protective plate 13. The protective plate 13 can be lifted by dragging the handle 14, so that the wires can be inserted into the power interface 12. The outer wall of the handle 14 is slidably connected to the inner wall of the protective shell 11, and the inner wall of the handle 14 is elastically connected to the limit block 16 through a reset spring b15. One end of the reset spring b15 is connected to the limit block 16. The inner wall of the handle 14 is fixedly connected, and the other end of the return spring b15 is fixedly connected to the bottom end of the limit block 16. Pressing the limit block 16 inward can squeeze the return spring b15 to retract it. At the same time, the elastic force generated by the deformation of the return spring b15 gives the limit block 16 a thrust in the opposite direction, prompting it to reset. Two sets of limit grooves 17 are provided on the side walls of the protective shell 11. The outer wall of the limit block 16 is engaged with the inner wall of the limit groove 17. After pressing the limit block 16 inward to fully retract it into the handle 14, and then releasing the engagement with the limit groove 17, the handle 14 can be dragged to drive the protective plate 13 to lift up.

[0033] Working principle: When it is necessary to insert the wire into the power interface 12, press the limit block 16 inward to disengage it from the limit groove 17, then drag the handle 14 to lift the protective plate 13, thereby exposing the power interface 12 and insert the wire. When the power interface 12 is fully exposed, the protective plate 13 slides to the top. At this time, release the limit block 16, and the return spring b15 pushes the limit block 16 into the limit groove 17 to fix the position of the protective plate 13 and prevent it from falling. Then use the magnet to adsorb the outer shell 2 and the display screen body 1 on the mounting base 3. At the same time, the elliptical block 9 will pass through the elliptical groove 10. At this time, pull the pull rod 6 outward to disengage the block 7 from the slot 8, and then rotate the pull rod 6 90°, so that the rotating shaft 4 drives the elliptical block 9 to rotate and buckle the inner wall of the outer shell 2 to prevent the edge of the display screen body 1 from warping. Then release the pull rod 6, and the return spring a5 pulls the pull rod 6 back to its original position, so that the block 7 is stuck in the slot 8 and fixed.
