Description

Technical Field

[0001] This utility model belongs to the field of flexible LED screen technology, specifically relating to a flexible and bendable LED strip screen module. Background Technology

[0002] LED display modules are the basic units that make up LED displays. They consist of LED chips, PCB boards, driver ICs, resistors, capacitors, and plastic components. The LED chips are arranged according to certain rules and then encapsulated and waterproofed to form standardized display modules. With the continuous advancement of technology, flexible and bendable LED display modules have gradually emerged. However, when bending, the bending range generally needs to be adjusted by adjusting the support structure to adapt to the installation requirements. However, some existing adjustment support structures often have certain shortcomings in use.

[0003] Chinese patent CN216119376U discloses a flexible and bendable LED display module. The flexible and bendable LED display module includes a flexible curved plate, an adjustment and mounting mechanism, and a fixing mechanism. The lower surface of the flexible curved plate has several mounting slots at equal intervals, and circuit boards are fixedly mounted in each of these slots. The upper surface of the flexible curved plate has several LED beads fixedly mounted at equal intervals, and the LED beads are electrically connected to the circuit boards. Several adjustment and mounting mechanisms are fixedly mounted at equal intervals on the lower surface of the flexible curved plate, and these mechanisms are symmetrically arranged. The flexible and bendable LED display module provided by this invention has a simple structure and is easy to operate. It can be adjusted in real time through the adjustment and mounting mechanisms provided on the device, increasing its adaptability during use and making it more convenient for users. This device has high practicality.

[0004] However, although the above technical solution can achieve the purpose of adjusting the flexible display screen, it requires the staff to rotate the fastening sleeve one by one, which is cumbersome. At the same time, the adjusted height can easily cause the bending of one side of the bottom of the flexible LED display screen to be irregular, thus affecting subsequent use. Therefore, it has certain limitations in use. Utility Model Content

[0013] (1) When using the flexible curved plate, the two sides of its bottom can be raised to a certain extent as needed to maintain a certain curvature, which increases the convenience of the overall device when using it. After adjustment, it can be supported in time to ensure the stable use of the flexible curved plate. At the same time, when adjusting the curvature of the flexible curved plate, you only need to turn the crank to raise its height.

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.

[0020] Example 1:

[0021] Please see Figures 1 to 3 As shown, the flexible and bendable LED strip screen module includes a mounting plate 1. An adjustment cavity 2 is fixedly connected to the middle of the top of the mounting plate 1. A connecting cavity 3 is fixedly connected to the surface of the adjustment cavity 2. Two cranks 4 are rotatably arranged inside the connecting cavity 3. A worm gear 5 is fixedly connected to one end of the cranks 4. A worm wheel 6 is engaged with the surface of the worm gear 5. A connecting plate 7 is engaged with the surface of the worm wheel 6. A lifting rod 8 is fixedly connected to one side of the connecting plate 7. The back of the lifting rod 8 is slidably connected to the inside of the adjustment cavity 2. A first top block 9 is provided above the lifting rod 8. A connecting rod 10 is fixedly connected to the top of the surface and back of the lifting rod 8. A second top block 11 is provided above the connecting rod 10. By setting the adjustment cavity 2, the connecting cavity 3 can be connected and fixed to it. The connecting cavity 3 and the adjustment cavity 2 are interconnected. By setting the handle 4, the worm 5 can be rotated, thereby causing the worm wheel 6 to rotate. The rotation of the worm wheel 6 drives the connecting plate 7 to rise. The connecting plate 7 is provided with teeth that match the surface of the worm wheel 6, which facilitates its rise and fall. Finally, it drives the lifting rod 8 to rise and fall. The structure at the top of the connecting rod 10 is the same as the structure on the lifting rod 8, both of which are provided with structures such as the universal ball 13. The worm wheel 6 is set inside the adjustment cavity 2 by rotating through the shaft.

[0022] A flexible curved plate 17 is provided above the mounting plate 1. Several LED beads 18 are provided on the top of the flexible curved plate 17, and a circuit board 19 is provided on the bottom of the flexible curved plate 17. The first top block 9 is provided to lift one side of the bottom of the flexible curved plate 17, so that the LED beads 18 can make the flexible curved plate 17 light up, the circuit board 19 can receive external signals, and the connecting rod 10 and the second top block 11 can better support the bottom of the flexible curved plate 17.

[0023] Mounting plate 1 has mounting grooves on both sides of its top, and two fastening bolts 20 are threaded into the inside of the mounting grooves. The mounting grooves allow the fastening bolts 20 to be screwed in, and the mounting plate 1 is then fixed in place by the fastening bolts 20.

[0024] Example 2:

[0025] Please see Figure 2 and Figure 3 As shown, a connecting block 12 is fixedly connected to the top of the lifting rod 8. A universal ball 13 is rotatably mounted inside the connecting block 12. Two connecting short rods 14 are fixedly connected to the surface of the universal ball 13, and the top of the connecting short rods 14 is fixedly connected to the bottom of the first top block 9. Through the setting of the connecting block 12, the universal ball 13 can be rotatably mounted inside it. The rotation of the universal ball 13 causes the connecting short rods 14 to drive the first top block 9 to rotate at a certain angle. The top of the first top block 9 is fixedly connected to the bottom of the flexible curved plate 17, and the top of the second top block 11 is fixedly connected to the bottom of the flexible curved plate 17.

[0026] A sliding groove 15 is provided on one side of the inner wall of the adjusting cavity 2. A sliding block is slidably connected inside the sliding groove 15. A limiting rod 16 is fixedly connected to one side of the sliding block, and one end of the limiting rod 16 is fixedly connected to the bottom end of one side of the lifting rod 8. The sliding groove 15 allows the sliding block to slide inside it. When the lifting rod 8 moves up and down, it drives the limiting rod 16 to move up and down, so that it plays a certain guiding and limiting role during movement.

[0027] The working principle of this utility model is as follows: When the operator needs to adjust the curvature of the flexible curved plate 17, the operator will turn the crank handle 4, which will then drive the worm gear 5 to rotate. The rotation of the worm gear 5 will drive the worm wheel 6 to rotate, and then the surface of the worm wheel 6 will mesh with the surface of the connecting plate 7, causing the connecting plate 7 to rise. Subsequently, the connecting plate 7 will drive the lifting rod 8 to rise, thereby causing the first top block 9 and the second top block 11 to rise, and thus causing one side of the bottom of the flexible curved plate 17 to be lifted, changing its curvature. During the rising process, the first top block 9 and the second top block 11 are adjusted to a certain angle with the flexible curved plate 17 through the universal ball 13, avoiding a large area of ​​straightening at the connection between the bottom of the flexible curved plate 17 and the first top block 9 and the second top block 11, so that it bends a certain curvature more naturally.

[0028] 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.
