[0018] Please see Figure 1-4 This utility model provides a technical solution: a smart signboard PWM dimming module, comprising: A fixed base 1 is fixedly connected to a support 3 on its top, and a sign light box 2 is fixedly connected to the top of the support 3. A stabilizing adjustment structure is located on the fixed base 1; The stabilizing adjustment structure includes a rotating shaft 9, two mounting seats 16, two moving wheels 8, a connecting slide plate 12, and two limiting rods 14. A rotating groove 7 is provided on one side of the fixed base 1, and the rotating shaft 9 is rotatably connected inside the rotating groove 7. Multiple insertion holes 15 are provided on the outer surface of the rotating shaft 9. Both mounting seats 16 are fixedly sleeved on the outer surface of the rotating shaft 9. Both moving wheels 8 are fixedly installed on the side of the corresponding mounting seat 16 away from the rotating shaft 9. A storage groove 6 is provided on the top of the fixed base 1, and the connecting slide plate 12 is slidably connected inside the storage groove 6. Both limiting rods 14 are fixedly connected on the side of the connecting slide plate 12 close to the rotating shaft 9. The ends of the two limiting rods 14 away from the connecting slide plate 12 slide out of the storage groove 6 and are inserted into the corresponding insertion holes 15. Two springs 13 are fixedly connected on the side of the connecting slide plate 12 away from the rotating shaft 9. The ends of the two springs 13 away from the connecting slide plate 12 are fixedly connected to the inside of the storage groove 6.

[0019] Both the connecting slide plate 12 and the storage slide 6 are convex structures, and there are two stabilizing adjustment structures, which are symmetrically arranged on both sides of the fixed base 1.

[0020] Multiple light tubes 11 are fixedly installed inside the sign light box 2. A PWM control module 10 is fixedly installed on the inner bottom wall of the fixed base 1. A cover plate 5 is bolted to one side of the sign light box 2. An anti-slip pad 4 is fixedly connected to the bottom of the fixed base 1. The anti-slip pad 4 is made of rubber.

[0021] Furthermore, when using this device, if it is necessary to move the sign, first pull the connecting slide plate 12 so that it overcomes the elastic force of the spring 13 and slides in the storage groove 6, causing the limiting rod 14 to disengage from the insertion hole 15 of the rotating shaft 9. At this time, rotate the rotating shaft 9. Since the two mounting seats 16 are fixedly sleeved on the rotating shaft 9, the two moving wheels 8 rotate accordingly. Rotate the moving wheels 8 to the position of contact with the ground, release the connecting slide plate 12, and under the elastic force of the spring 13, the connecting slide plate 12 resets. The limiting rod 14 is reinserted into the corresponding insertion hole 15 of the rotating shaft 9 to limit the rotation shaft 9. At this time, the sign can be pushed to the designated position by the moving wheels 8.

[0022] When the sign is moved to the target position and needs to be placed stably, pull the connecting slide plate 12 again to disengage the limiting rod 14 from the insertion hole 15, rotate the rotating shaft 9 in the opposite direction to rotate the moving wheel 8 to the side of the fixed base 1 away from the ground, and then release the connecting slide plate 12. The limiting rod 14 is then inserted into the insertion hole 15 again to fix the rotating shaft 9. At this time, the anti-slip pad 4 at the bottom of the fixed base 1 is in full contact with the ground, which increases the contact area between the sign and the ground and improves stability.

[0023] In terms of lighting, the PWM control module 10 sends control signals to multiple lamps 11 inside the signage light box 2 according to actual needs. It adjusts the brightness of the lamps 11 through pulse width modulation technology to achieve intelligent dimming function. By opening or closing the cover 5 on one side of the signage light box 2, the lamps 11 and other components inside the light box can be maintained and replaced.

[0024] With the set stable adjustment structure, the sign can be moved easily to meet the needs of different scenarios. When moving, the moving wheel 8 can quickly switch to working state to facilitate pushing the sign. After reaching the designated position, the moving wheel 8 can be retracted, and the anti-slip pad 4 can be used to increase the contact area with the ground, improve stability, and prevent the sign from shaking or tipping over due to external force or uneven ground, thus further improving the stability of the sign placement.
