The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1-4 ,in Figure 1 This is a structural diagram of the bulletin board. Figure 2 This is a front view of the bulletin board structure. Figure 3 This is a structural side view of the bulletin board. Figure 4 yes Figure 3 Enlarged view of the local structure at point A.

[0021] This utility model provides a bulletin board structure, including a support frame 101, an electronic display screen body 102, a protective glass 103, and a cleaning module. The electronic display screen body 102 is fixedly connected to the support frame 101, and the protective glass 103 is provided on the outer side of the electronic display screen body 102.

[0022] The cleaning module includes a drive unit, a mounting frame 106, a connecting unit, a mounting plate 110, and a wiping cotton 111. The drive unit is fixedly connected to the support frame 101. The mounting frame 106 is connected to the drive unit. The connecting unit is fixedly connected to the mounting frame 106 and is located between the mounting frame 106 and the electronic display screen body 102. The mounting plate 110 is fixedly connected to the connecting unit. The wiping cotton 111 is provided on the mounting plate 110 and is attached to the outer wall of the protective glass 103.

[0023] In this embodiment, photovoltaic power generation can be used to power the electronic display screen body 102. The support frame 101 supports the electronic display screen body 102. Viewers can view the promotional content displayed on the electronic display screen through the protective glass 103. Before or after viewing, the dust adhering to the protective glass 103 can be cleaned. The cleaning process is as follows: the drive unit is controlled to operate, and the drive unit drives the mounting frame 106 to move laterally. The connecting unit connects the mounting frame 106 and the mounting plate 110. As the mounting frame 106 moves, the wiping cotton 111 moves. The wiping cotton 111 adheres to the protective glass 103, and the wiping cotton 111 is used to wipe the protective glass 103, thereby facilitating the cleaning of the protective glass 103 and improving the viewing experience of the electronic display screen body 102.

[0024] Furthermore, the cleaning module also includes an air pump 112, a delivery pipe 113, and multiple nozzles 114. The air pump 112 is fixedly connected to the mounting bracket 106 and is located on the outer side wall of the mounting bracket 106. One end of the delivery pipe 113 is connected to the output end of the air pump 112, and each nozzle 114 is connected to the delivery pipe 113.

[0025] In this embodiment, before the wiping cotton 111 cleans the protective glass 103, the air pump 112 is controlled to operate, and the delivery pipe 113 delivers airflow to each of the nozzles 114. The airflow blows away large particles or some dust on the protective glass 103, preventing large particles from scratching the protective glass 103 during the subsequent movement of the wiping cotton 111, while also blowing away some dust, thus improving the cleaning effect on the protective glass 103.

[0026] Furthermore, the cleaning module also includes a female adhesive sheet 115 and a female adhesive sheet 116. The female adhesive sheet 115 is fixedly connected to the mounting plate 110 and is located on the outer side wall of the mounting plate 110. The female adhesive sheet 116 is fixedly connected to the wiping cotton 111 and is located on the outer side wall of the wiping cotton 111. The female adhesive sheet 115 and the female adhesive sheet 116 can be detachably connected.

[0027] In this embodiment, the mother adhesive sheet 115 and the daughter adhesive sheet 116 are detachable, and the wiping cotton 111 can be removed from the mounting plate 110 for processing after use.

[0028] Furthermore, the connecting unit includes a retaining spring 107, a fixing cylinder 108, and a connecting rod 109. The two ends of the retaining spring 107 are respectively connected to the mounting bracket 106 and the mounting plate 110.

One end of the connecting rod 109 is slidably connected to the fixing cylinder 108, and the other end of the connecting rod 109 is fixedly connected to the mounting plate 110. The retaining spring 107 surrounds the outer side walls of the fixing cylinder 108 and the connecting rod 109.

[0029] In this embodiment, under the action of the holding spring 107, the wiping cotton 111 is always in contact with the outer wall of the wiping cotton 111. The holding spring 107 surrounds the outer walls of the fixed cylinder 108 and the connecting rod 109 respectively. The connecting rod 109 slides inside the fixed cylinder 108. The connecting rod 109 cooperates with the fixed cylinder 108 to improve the stability of the holding spring 107.

[0030] Furthermore, the drive unit includes an electric lead screw 104 and a sleeve 105. The electric lead screw 104 is fixedly connected to the mounting bracket 106 and is located on the outer side wall of the mounting bracket 106. The sleeve 105 is rotatably connected to the output end of the electric lead screw 104. The mounting bracket 106 is fixedly connected to the sleeve 105 and is located on the outer side wall of the sleeve 105.

[0031] In this embodiment, the operation of the electric lead screw 104 is controlled, and the operation of the sleeve 105 and the electric lead screw 104 drives the mounting frame 106 to move laterally. The connecting unit connects the mounting frame 106 and the mounting plate 110, thereby driving the wiping cotton 111 to move during the movement of the mounting frame 106. The wiping cotton 111 adheres to the protective glass 103, and the protective glass 103 is wiped using the wiping cotton 111.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
