Problems solved by technology

[0002] In the existing traditional LED display technology, the light source needs to be supported by a carrier, and most of them are flat LED display screens, which cannot produce image suspension, overall perspective effects, and more three-dimensional visual effects
[0003] Existing rotary imaging devices that use LED array light sources are generally driven by direct drive motors, and the output torque is too small, resulting in technical defects such as small display area, low display image definition, low picture stability, and inaccurate image positioning. , unable to provide greater value for visual communication
Due to technical reasons, the size of the existing equipment is too small, and the diameter of the display area is within 600mm, so it is not possible to display large-scale equipment, such as displaying in airports, railway stations, pedestrian streets, large shopping malls, banks, etc.

Embodiment 1

[0032] Such as Figure 1~4 As shown, the large-scale POV-LED display device and the solution to the dynamic balance in the display process of the present invention include an odd number of more than 1 special-shaped rotating arms 1 connected to the rotating arm fixed plate 3, and the special-shaped rotating arm 1 is far away from the rotating arm. A counterweight end cover 2 is arranged on one end surface of the arm fixed plate 3, and a hollow motor unit 4 is installed on the rear end surface of the rotating arm fixed plate 3, and a slip ring 5 is installed on the rear end of the hollow motor unit 4. The rotating arm fixed disk 3 coincides with the center of circle of the hollow motor unit 4 and the slip ring 5 . The installation of the hollow motor unit 4 can output kinetic energy through the hollow motor 41, and the driving torque is larger, which reduces the defect of weak single-axis output stability of the direct drive motor, and provides better image stability for large-...

Embodiment 2

[0036] Such as Figure 5 As shown, the only difference between this embodiment and Embodiment 1 is that the hollow motor unit 4 includes a hollow motor 41, a motor bracket 42, and a bearing seat 43, and the hollow motor 41 is installed on the motor bracket 42, and the hollow motor 41 and the The rotating arm fixed disk 3 is connected, the bearing seat 43 is installed on the other side of the motor support 42 , and the slip ring 5 is sleeved on the bearing seat 43 . Driven by the hollow motor, the output stability under heavy load conditions is improved, and the driving torque is larger by using the hollow motor drive, which reduces the defect that the single-axis output stability of the direct drive motor is not strong, and provides better support for large-scale suspended transparent display devices. image stability. The motor bracket 42 fixes the hollow motor 41 and the bearing seat 43, and the lower end surface of the motor bracket 42 is provided with a support assembly 6,...

Embodiment 3

[0039] This embodiment is optimized on the basis of Embodiment 1, and the linear distance from the center point of the rotating arm fixed plate 3 to the counterweight end cover 2 provided on the special-shaped rotating arm 1 is greater than 300 mm. At present, the size of the equipment on the market is too small due to technical reasons, and the diameter of the display area is within 600mm, which cannot realize a large-scale display. The special-shaped rotating arm and the combination of the rotating arm fixed plate and the counterweight end cover adopted in the present invention can realize the display area. The diameter is greater than 600mm, meeting the display needs of large venues.

Abstract

The invention discloses large-scale POV-LED display equipment and a solution for dynamic balance in the display process. The large-scale POV-LED display equipment comprises one or more odd-numbered abnormal-typed rotary arm which is connected to a rotary arm fixed disk. The large-scale POV-LED display equipment is characterized by further comprising a counter weight end cover, wherein the counter weight end cover is arranged on the end surface of one end, away from the rotary arm fixed disk, of the abnormal-typed rotary arm. A hollow motor group is installed on the end surface of the rear end of the rotary arm fixed disk; the rear end of the hollow motor group is provided with a sliding ring; the rotary arm fixed disk is coincidence with the circle centers of the hollow motor group and the sliding ring. An end cover is designed at the outer end of the abnormal-typed rotary arm; fine tuning is conducted on the weight of the rotary arm individual by separate counterweight, and the overall dynamic balance of the large-sized rotary arm is improved to enhance the stability. The hollow motor group is installed to output kinetic energy, the drive torque is larger, the shortcoming that the stability of direct drive motor single shaft output is not strong is solved, and the better image stability is provided for large-scale suspension transparent display equipment.
