Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically a rotatable LED display driving structure. Background Technology

[0002] In today's information age, LED displays are widely used in advertising, information presentation, stage performances, and many other fields. With the increasing diversification of application scenarios, people are placing higher demands on the flexibility of LED displays.

[0003] Traditional LED displays are typically fixed in place, making it difficult to adjust their display angle and orientation, limiting content display to a single direction. In complex environments, such as shopping mall atriums and exhibition halls, fixed-direction displays cannot meet the viewing needs of audiences in different positions, thus limiting the information dissemination range. Furthermore, the size and shape of the display planes vary across different venues, and traditional display bases struggle to adapt to these variations, leading to instability. In addition, in stage performances and other scenarios, LED displays require flexible angle and orientation adjustments to create better visual effects and complement program content and stage design. However, existing display driving structures cannot meet these diverse and dynamic display needs. Therefore, those skilled in the art have provided a rotatable LED display driving structure to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a rotatable LED display driving structure to solve the problems mentioned in the background art.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a rotatable LED display driving structure includes a display body 1, a housing 3, an annular base 6, and a support frame 4. The annular base 6 is located below the housing 3, and several guide rails 7 are fixedly connected to the annular base 6. The upper side of each guide rail 7 is fixedly connected to the housing 3. Each guide rail 7 has a groove at its lower end, and a slide bar 8 is slidably connected within each groove. A base 10 is rotatably connected to the upper end of the housing 3, and a support frame 4 is fixedly connected to the upper end of the base 10. A rotating seat is fixedly connected to the upper end of the support frame 4, and a rotating block 101 is rotatably connected within the rotating seat. The front end of the rotating block 101 is fixedly connected to the display body 1. A second servo motor 13 is fixedly installed inside the housing 3. The power output end of the second servo motor 13 is fixedly connected to the worm gear 14. The lower end of the chassis 10 is fixedly connected to the movable shaft 11, which is rotatably connected to the housing 3. The outer ring of the movable shaft 11 is fixedly connected to the worm wheel 12, which meshes with the worm gear 14. One end of each slide bar 8 is fixedly connected to an arc plate 9. Each guide rail 7 is threadedly connected to a tensioning disc 701, which can fix the slide bar 8 in the guide rail 7. The controller 2 is fixedly installed on the left side of the housing 3. The first servo motor 5 is fixedly installed on one side of the rotating seat. The power output end of the first servo motor 5 is fixedly connected to the rotating shaft, which is rotatably connected to the rotating seat. The rotating block 101 is fixedly connected to the rotating shaft.

[0022] The working principle of this utility model is as follows: During placement, a guide rail 7 is provided on the annular base 6, and a slider 8 can slide in the groove at the lower end of the guide rail 7. By moving the slider 8 within the guide rail 7, the extension length of the slider 8 can be adjusted. When the display screen needs to be placed on a plane of different sizes, the position of the slider 8 can be adjusted to make the base better contact the placement surface, thereby enhancing the stability of the annular base 6 and adapting to different placement environments. After adjusting the position of the slider 8, tightening the threaded fastener 701 on the guide rail 7 will fix the slider 8 within the guide rail 7 and prevent it from sliding freely. In addition, when it is necessary to adjust the angle of the display screen, a rotating block 101 is rotatably connected inside the rotating seat. The front end of the rotating block 101 is fixedly connected to the display screen body 1. A first servo motor 5 is installed on one side of the rotating seat, and its power output end is connected to the rotating shaft. The rotating shaft is rotatably connected to the rotating seat, and the rotating block 101 is fixed on the rotating shaft. After starting the first servo motor 5, the motor drives... The rotating shaft rotates, which in turn drives the rotating block 101 to rotate. The rotating block 101 then drives the main body of the display screen 1 to rotate, thus enabling the adjustment of the display screen angle to meet the user's needs for viewing the display screen content from different angles. When the display screen orientation needs to be adjusted, a second servo motor 13 is installed inside the housing 3, and its power output end is connected to the worm gear 14. The movable shaft 11, which is fixedly connected to the lower end of the chassis 10, is rotatably connected to the housing 3. The worm wheel 12, which is fixedly connected to the outer ring of the movable shaft 11, meshes with the worm gear 14. When the second servo motor 13 is started, the worm gear 14 rotates. Since the worm wheel 12 meshes with the worm gear 14, the worm gear 14 drives the worm wheel 12 to rotate. The worm wheel 12 drives the movable shaft 11 to rotate, which in turn drives the chassis 10 to rotate. The chassis 10 drives the fixedly connected support frame 4 to rotate, thereby causing the display screen fixed on the support frame 4 to rotate. This enables the adjustment of the display screen orientation, allowing the display screen to face different directions to display content.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
