[0002] The intelligent brightness adjustment controller for illuminated signs is a device used to control the brightness of various illuminated signs, such as billboards and signage. It is widely used in commercial advertising, urban lighting, and other fields. In practical applications, illuminated signs need to automatically adjust their brightness according to changes in ambient light to ensure clear visibility while saving energy.

[0003] The existing intelligent brightness adjustment controller for illuminated signs has the following shortcomings:

[0004] Firstly, traditional controllers' brightness detectors lack automatic dust removal functions. When exposed to outdoor environments for extended periods, dust and dirt easily accumulate on the detection surface, leading to inaccurate detection data and consequently causing deviations in the brightness adjustment of illuminated signs. Secondly, existing controllers are mostly installed using direct screw fixing or complex snap-fit ​​structures. Installation requires repeated alignment and tightening of screws, which is cumbersome and time-consuming. Disassembly also requires tools, resulting in low efficiency. Furthermore, repeated disassembly and assembly can easily damage the installation parts, causing great inconvenience for equipment maintenance and replacement. Utility Model Content

Through an innovatively designed automatic dust removal structure and a convenient quick-disassembly structure, it effectively solves the problems of dust accumulation affecting the detection accuracy of brightness detectors and the inconvenience of installing and disassembling the controller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent brightness adjustment controller for illuminated characters, comprising a controller body, a support frame fixedly connected to the bottom of the controller body, a brightness detector fixedly connected to the front side of the support frame, and a fixing component fixedly connected to the rear side of the controller body.

[0007] An electric motor is fixedly connected to the bottom rear side of the support frame. An annular connecting groove is opened on the front side of the support frame. The output shaft of the electric motor passes through the lower part of the annular connecting groove and is fixedly connected to a drive wheel. A driven gear ring is meshed with the outer surface of the drive wheel. The driven gear ring is rotatably connected to the inner surface of the annular connecting groove. An arc-shaped rotating plate is rotatably connected to the inner surface of the driven gear ring. A dust cleaning cotton brush is fixedly connected to the inner surface of the arc-shaped rotating plate.

[0008] Preferably, the upper and lower ends of the arc-shaped rotating plate are fixedly connected to connecting columns, and the upper and lower sides of the inner circumference of the driven toothed ring are provided with movable grooves. The end of the connecting column away from the arc-shaped rotating plate passes through the interior of the movable groove and a spiral spring is fixedly connected to its outer surface. The end of the spiral spring away from the connecting column is fixedly connected to the inner wall of the movable groove.

[0009] Preferably, a rotating push plate is fixedly connected to the bottom rear side of the arc-shaped rotating plate, an annular sliding groove is provided on the inner rear side of the annular connecting groove, and a protruding plate is fixedly connected to the bottom of the inner surface of the annular sliding groove.

[0010] Preferably, the fixing component includes a connecting plate, which is fixedly connected to the rear side of the controller body, and the connecting plate has a through-hole connecting slot in the middle.

[0011] Preferably, a plug post is slidably inserted into the inner surface of the connecting slot, and a pre-fixing plate is fixedly connected to the rear end of the plug post. Fastening bolts are provided at all four corners of the pre-fixing plate.

[0012] Preferably, positioning slots are provided on both the left and right sides of the plug-in post, and positioning components are provided on both the left and right sides of the connecting plate.

[0013] Preferably, the positioning component includes a pull plate, and two pull plates are respectively disposed on the left and right sides of the connecting plate, and a sliding insert plate is fixedly connected to the opposite surfaces of the two pull plates.

[0014] Preferably, the connecting plate has connecting grooves on both the left and right sides, the connecting grooves extending to the inner surface of the connecting slot, and the sliding plate is slidably connected inside the connecting groove, with the end away from the pull plate extending into the interior of the positioning slot.

[0015] Preferably, the upper and lower sides of the sliding plate are fixedly connected to connecting slide plates, and the middle of the connecting slide plates is slidably connected to a guide slide column that runs through the left and right sides.

[0016] Preferably, the two guide slides are fixedly connected to the upper and lower sides of the inner wall of the connecting slide groove, respectively.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. In this utility model, an electric motor drives the drive wheel to rotate, which in turn drives the driven gear ring to rotate within the annular connecting groove. This, in turn, drives the arc-shaped rotating plate to rotate vertically. During the rotation, the rotating push plate rotates away from the front of the convex plate. After losing its restraint, under the action of the spiral spring, the connecting column drives the arc-shaped rotating plate to rotate horizontally, causing the cleaning brush to adhere to the outer surface of the brightness detector. Subsequently, the continuous vertical rotation of the arc-shaped rotating plate drives the cleaning brush to thoroughly clean the surface of the detector. When the cleaning is completed and the plate returns to its original position, the rotating push plate is squeezed out of the annular groove by the convex plate, and the arc-shaped rotating plate automatically retracts into the annular connecting groove. This structure realizes automated and periodic cleaning of the brightness detector without manual intervention, effectively avoiding dust accumulation from affecting the detection accuracy and ensuring the accuracy and stability of the brightness adjustment of illuminated characters.

[0019] 2. In this utility model, when installing the controller body, the pre-fixed plate is first fixed to the wall with fastening bolts, and then the connecting slot of the connecting plate is put into the plug-in post. The top spring pushes the sliding plug-in plate to automatically insert into the positioning slot, and the fixing is completed quickly. When disassembling, simply pull the pull plate to overcome the spring force and pull the sliding plug-in plate out of the positioning slot to easily remove the controller. This quick-release structure does not require the use of screwdrivers or other tools, and the operation is simple and convenient, which greatly shortens the installation and disassembly time, improves work efficiency, and reduces the damage to parts caused by frequent disassembly and assembly, and facilitates the maintenance and replacement of equipment.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes a controller body 1, a support frame 2 fixedly connected to the bottom of the controller body 1, a brightness detector 3 fixedly connected to the front side of the support frame 2, a fixing assembly 4 fixedly connected to the rear side of the controller body 1, an electric motor 21 fixedly connected to the bottom rear side of the support frame 2, an annular connecting groove 22 opened on the front side of the support frame 2, the output shaft of the electric motor 21 passes through the lower part of the annular connecting groove 22 and is fixedly connected to a drive wheel 23, a driven gear ring 24 meshing with the outer surface of the drive wheel 23, the driven gear ring 24 rotatably connected to the inner surface of the annular connecting groove 22, and a driven gear ring 24 rotatably connected to the inner surface of the driven gear ring 24. An arc-shaped rotating plate 25 has a cleaning cotton brush 26 fixedly connected to its inner surface. Connecting posts 27 are fixedly connected to both the upper and lower ends of the arc-shaped rotating plate 25. Movable grooves are opened on both the upper and lower sides of the inner circumference of the driven toothed ring 24. The end of the connecting post 27 away from the arc-shaped rotating plate 25 passes through the interior of the movable groove and a spiral spring 28 is fixedly connected to its outer surface. The end of the spiral spring 28 away from the connecting post 27 is fixedly connected to the inner wall of the movable groove. A rotating push plate 29 is fixedly connected to the rear bottom of the arc-shaped rotating plate 25. An annular sliding groove 210 is opened on the rear inner surface of the annular connecting groove 22. A protruding plate 211 is fixedly connected to the bottom of the inner surface of the annular sliding groove 210.

[0029] The overall effect achieved by Embodiment 1 is as follows: When the brightness detector 3 needs to be cleaned, the electric motor 21 is started. The output shaft of the electric motor 21 drives the drive wheel 23 to rotate. Since the drive wheel 23 meshes with the driven gear ring 24, the driven gear ring 24 begins to move in a circular motion within the annular connecting groove 22. As the driven gear ring 24 rotates, the arc-shaped rotating plate 25 inside it also begins to rotate vertically. During the rotation, the rotating push plate 29 gradually rotates away from the front side of the convex plate 211. At this time, the arc-shaped rotating plate 25, which was originally restricted by the convex plate 211, is no longer restricted. Under the elastic force of the spiral spring 28, the connecting column 27 drives the arc-shaped rotating plate 25 to rotate horizontally, thus cleaning the dust. The cotton brush 26 adheres to the outer surface of the brightness detector 3. Subsequently, the driven toothed ring 24 continues to rotate, driving the arc-shaped rotating plate 25 to continue rotating vertically. The cleaning cotton brush 26 continuously wipes the surface of the brightness detector 3, achieving a comprehensive cleaning of dust and dirt on the detector surface. When cleaning is complete, as the arc-shaped rotating plate 25 returns to its original position, the rotating push plate 29 is once again squeezed by the convex plate 211 and rotates out of the annular slide groove 210. Under the obstruction of the convex plate 211 and the action of the spiral spring 28, the arc-shaped rotating plate 25 automatically retracts into the annular connecting groove 22, waiting for the next cleaning instruction. This achieves automated and periodic cleaning of the brightness detector 3, ensuring the accuracy of the detection data.

[0030] Example 2: As Figure 4 and Figure 5 As shown, this utility model provides a technical solution: the fixing component 4 includes a connecting plate 41, which is fixedly connected to the rear side of the controller body 1. A connecting slot 42 that runs through the front and rear is opened in the middle of the connecting plate 41. A plug-in post 43 is slidably inserted into the inner surface of the connecting slot 42. A pre-fixing plate 44 is fixedly connected to the rear end of the plug-in post 43. Fastening bolts 45 are provided at the four corners of the pre-fixing plate 44. Positioning slots 46 are opened on both the left and right sides of the plug-in post 43. Positioning components 47 are provided on both the left and right sides of the connecting plate 41. The positioning components 47 include pull plates 471. Two pull plates 471 are respectively arranged on the left and right sides of the connecting plate 41. The opposite surfaces of the two pull plates 471 are... A sliding insert plate 472 is fixedly connected. Connecting grooves are provided on both the left and right sides of the connecting plate 41. The connecting grooves extend to the inner surface of the connecting slot 42. The sliding insert plate 472 is slidably connected inside the connecting groove, and one end away from the pull plate 471 extends into the interior of the positioning slot 46. Connecting slide plates 473 are fixedly connected to both the upper and lower sides of the sliding insert plate 472. A guide slide post 474 extending from left to right is slidably connected to the middle of the connecting slide post 473. The two guide slide posts 474 are fixedly connected to the upper and lower sides of the inner wall of the connecting groove, respectively. A clamping spring 475 is provided on the outer surface of the guide slide post 474. The clamping spring 475 is located on the side of the connecting slide post 473 away from the insert post 43.

[0031] The effect achieved by the entire embodiment 2 is as follows: When installing the controller body 1, firstly, the pre-fixed plate 44 is fixed to the wall or other installation position using fastening bolts 45. Then, the connecting slot 42 of the connecting plate 41 on the rear side of the controller body 1 is aligned with the plug-in post 43 and put on. When the connecting slot 42 is completely put on the plug-in post 43, so that the positioning slot 46 corresponds to the sliding plug 472, the tightening spring 475 can push the connecting slide plate 473 to drive the sliding plug 472 to automatically insert into the positioning slot 46, thereby quickly and firmly completing the fixing of the controller body 1. When it is necessary to disassemble the controller body 1, simply pull the pull plates 471 on both sides at the same time. The pull plates 471 drive the sliding plug 472 to move to both sides against the elastic force of the tightening spring 475, so that the sliding plug 472 is pulled out from the positioning slot 46. At this time, the controller body 1 can be easily removed. The entire installation and disassembly process does not require additional tools and is simple and efficient to operate.

[0032] The working principle of the entire device is as follows: Before the device is started, the controller body 1 is installed in the designated position by the fixing component 4. First, the pre-fixed plate 44 is fixed to the wall, billboard bracket and other load-bearing surfaces by the fastening bolts 45. Then, the connecting slot 42 of the connecting plate 41 on the back of the controller body 1 is aligned with the plug post 43 and inserted. When the connecting slot 42 is fully inserted into the plug post 43 and the positioning slot 46 is precisely aligned with the sliding plug plate 472, the tightening spring 475 can push the connecting slide plate 473 to drive the sliding plug plate 472 to quickly insert into the positioning slot 46, thereby achieving the rapid fixing of the controller body 1.

[0033] After the equipment is started, the brightness detector 3 begins to monitor the ambient light intensity in real time. The brightness detector 3 has a built-in photoelectric sensing element. During the operation of the equipment, the electric motor 21 is started, and its output shaft drives the drive wheel 23 to rotate. Through gear transmission, the driven gear ring 24 rotates in the annular connecting groove 22. In the initial stage of rotation, the arc-shaped rotating plate 25 rotates vertically with the driven gear ring 24. The rotating push plate 29 gradually gets away from the obstruction of the convex plate 211. The arc-shaped rotating plate 25 rotates horizontally under the elastic force of the spiral spring 28, so that the cleaning cotton brush 26 is in contact with the surface of the brightness detector 3. Subsequently, the driven gear ring 24 continues to rotate, driving the arc-shaped rotating plate 25 to perform compound motion. The cleaning cotton brush 26 wipes and cleans the surface of the brightness detector 3 in all directions. After cleaning, the arc-shaped rotating plate 25 rotates back to the initial position, the rotating push plate 29 is blocked by the convex plate 211 again, and the arc-shaped rotating plate 25 is retracted into the annular connecting groove 22 under the action of the spiral spring 28.

[0034] When the equipment malfunctions or requires maintenance or upgrades, the operator only needs to pull the pull plates 471 on both sides at the same time. The pull plates 471 drive the sliding insert plate 472 to move to both sides against the elastic force of the top spring 475, so that the sliding insert plate 472 disengages from the positioning slot 46, and the controller body 1 can be easily removed from the fixed position. The removed controller body 1 can be taken back to the maintenance workshop for detailed testing and maintenance. After the maintenance is completed, it can be quickly installed back into the original position through the above quick-release structure, which greatly shortens the equipment downtime and improves maintenance efficiency.

[0035] The entire device effectively solves the problems of low detection accuracy and inconvenient installation and disassembly of traditional controllers through the coordinated operation of the automatic dust removal structure, the convenient and quick-disassembly structure and the brightness adjustment control system. It improves the practicality, reliability and maintenance convenience of the intelligent brightness adjustment controller for illuminated signs, and can better meet the application needs of commercial advertising, urban lighting and other fields.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
