At the same time, a compatible module mounting plate is provided on the module mounting plate, and the module mounting plate can be detachably installed on the module mounting plate, which can be suitable for the installation of power modules, control modules and signal receiving modules of different manufacturers' specifications, making installation and disassembly more convenient.

[0035] This embodiment includes an advertising screen body 3, an outer shell 1 arranged outside the advertising screen body 3 and a back cover 2 covering the outer shell 1, the outer shell 1 includes a tempered glass 11 and an outer frame 12 arranged on the outer periphery of the tempered glass 11, one end of the outer frame 12 is connected to the tempered glass 11 and forms an installation cavity 4 with the tempered glass 11 for installing and fixing the advertising screen body 3, and the other end is connected to the back cover 2, the outer frame 12 is provided with a first mosaic waterproof structure 13 for embedding and clamping the tempered glass 11 and waterproofing, and the end of the outer shell 1 opposite to the back cover 2 is provided with a waterproof drainage structure 14.

[0036] The smart advertising screen provided in this embodiment has a first waterproof structure 13 on the outer frame for the tempered glass 11 to be embedded and clamped and is waterproof, so that the tempered glass 11 and the outer frame 12 form a waterproof and dustproof installation cavity 4 for installing the advertising screen body, which effectively prevents water mist and dust from entering the smart advertising screen through the gap between the tempered glass 11 and the outer frame 12, thereby avoiding problems such as short circuit caused by water mist to the circuit inside the smart advertising screen; at the same time, a waterproof drainage structure 14 is provided at the end opposite to the outer shell 1 and the back cover 2, which can effectively prevent water mist from entering the smart advertising screen through the gap after the outer shell 1 and the back cover 2 are covered, thereby effectively protecting the circuit inside the smart advertising screen; moreover, the advertising screen body 3 is installed in the installation cavity 4 surrounded by the tempered glass 11 and the outer frame 12. During maintenance, it is only necessary to open the back cover 2 to inspect the circuit on the back of the advertising screen body 3, without the need to remove the advertising screen body 3 as a whole and then inspect the circuit on the back of the advertising screen body 3. It has a simple structure and is easy to operate.

[0037] Furthermore, the outer frame 12 and the back cover 2 described in this embodiment are both made of aluminum and provided with an oxidation protection layer on the surface. The outer frame 12 and the back cover 2 made of aluminum not only make the smart advertising screen lighter, but also achieve better heat dissipation effect. In addition, the surface is provided with an oxidation protection layer, which can prevent the smart advertising screen from being oxidized and rusted, and prolong the service life.

[0038] Furthermore, the first embedded waterproof structure 13 includes a first fixing plate 131 and a first supporting waterproof platform 132 provided at one end of the outer frame 12, and a first embedded groove 133 for embedding and fixing the tempered glass 11 is provided between the first fixing plate 131 and the first supporting waterproof platform 132. Figure 8 As shown, the first fixing plate 131 and the first supporting waterproof platform 132 are arranged in sequence from the outside of the outer frame 12 to the inside close to the back cover 2, the tempered glass 11 is installed in the first engaging groove 133, and the first fixing plate 131 and the first supporting waterproof platform 132 are respectively located on both sides of the tempered glass 11 to provide force support for the tempered glass 11, so that the tempered glass 11 and the outer frame 12 form a sealed and waterproof outer frame.

[0039] Furthermore, the length of the first supporting waterproof platform 132 extending along the opening direction of the first interlocking groove 133 is greater than the length of the first fixed plate 131 extending along the opening direction of the first interlocking groove 133. With this structure, when water mist enters the first interlocking groove 133 through the first fixed plate 131, since the length of the first supporting waterproof platform 132 extending along the opening of the first interlocking groove 133 is greater than the length of the first fixed plate 131 extending along the opening direction of the first interlocking groove 133, the water mist flowing into the first interlocking groove 133 will not enter the interior of the smart advertising screen through the first supporting waterproof platform 132, but will flow out from the first fixed plate 131 with a shorter extension length on one side of the first interlocking groove 133, thereby achieving effective waterproofing and dustproofing.

[0040] Furthermore, the first supporting waterproof platform 132 is a hollow structure, which makes the smart advertising screen lighter. At the same time, a first reinforcing plate 1321 is provided in the first supporting waterproof platform 132 to ensure that the first supporting waterproof platform 132 has sufficient strength and is not easily deformed when continuously providing support for the tempered glass 11.

[0041] Furthermore, the end of the first fixing plate 131 extends in a direction perpendicular to the tempered glass 11 and fits with the tempered glass 11, so that the first fixing plate 131 fits more closely with the tempered glass 11 and the sealing effect is better.

[0042] Furthermore, a waterproof sealing strip is provided between the first embedding groove 133 and the tempered glass 11, so that water mist and dust are not easy to enter the first embedding groove 133 through the gap between the first embedding groove 133 and the tempered glass 11, thereby achieving a better sealing effect.

[0043] Furthermore, the back cover 2 includes a sealing plate 21 and a sealing plate outer frame 22 for mounting and fixing the sealing plate 21. The sealing plate outer frame 22 is provided with a second embedded waterproof structure 23 for embedding and clamping the sealing plate 21 and waterproofing. The second embedded waterproof structure 23 includes a second fixed plate 231 and a second supporting waterproof platform 232 provided at one end of the sealing plate outer frame 22. A second embedded groove 233 for embedding and fixing the sealing plate 21 is provided between the second fixed plate 231 and the second supporting waterproof platform 232. Figure 8 As shown, the second fixing plate 231 and the second supporting waterproof platform 232 are arranged in sequence from the outer side of the back cover 2 to the inner side close to the outer shell 1, and the sealing plate 21 is installed in the second fitting groove 233. The second fixing plate 231 and the second supporting waterproof platform 232 are respectively located on both sides of the sealing plate 21 to provide force support for the sealing plate 21, so that the sealing plate 21 and the sealing plate outer frame 22 form a sealed and waterproof outer frame.

[0044] Furthermore, the length of the second supporting waterproof platform 232 extending along the opening direction of the second interlocking groove 233 is greater than the length of the second fixed plate 231 extending along the opening direction of the second interlocking groove 233. With this structure, when water mist enters the second interlocking groove 233 through the second fixed plate 231, since the length of the second supporting waterproof platform 232 extending along the opening of the second interlocking groove 233 is greater than the length of the second fixed plate 231 extending along the opening direction of the second interlocking groove 233, the water mist flowing into the second interlocking groove 233 will not enter the interior of the smart advertising screen through the second supporting waterproof platform 232, but will flow out from the second fixed plate 231 with a shorter extension length on one side of the second interlocking groove 233, thereby achieving effective waterproofing and dustproofing.

[0045] Furthermore, the second supporting waterproof platform 232 is a hollow structure, which makes the smart advertising screen lighter. At the same time, a second reinforcing plate 2321 is provided inside the second supporting waterproof platform 232 to ensure that the second supporting waterproof platform 232 has sufficient strength and is not easily deformed when continuously providing support for the sealing plate 21.

[0046] Furthermore, the end of the second fixing plate 231 extends in a direction perpendicular to the sealing plate 21 and fits with the sealing plate 21, and a waterproof sealing strip is provided between the second fitting groove 233 and the sealing plate 21, so that the second fixing plate 231 and the sealing plate 21 fit more closely, preventing water mist and dust from entering the second fitting groove 233 through the gap between the second fitting groove 233 and the sealing plate 21, thereby achieving a better sealing effect.

[0047] Furthermore, the waterproof drainage structure 14 includes a waterproof portion 141 disposed horizontally on the housing 1 and a drainage portion 142 disposed vertically on the housing 1. One end of the waterproof portion 141 is fixedly connected to the housing 1, and the other end extends toward the rear cover 2 so that the waterproof portion 141 is opposite to the gap after the housing 1 and the rear cover 2 are covered. The drainage portion 142 is disposed on both sides of the waterproof portion 141. Figure 2 As shown, the waterproof part 141 and the drainage part 142 are both opposite to the gap after the outer shell 1 and the back cover 2 are covered. The waterproof part 141 arranged in the horizontal direction of the outer shell 1 can effectively block rain and fog. The drainage part 142 is arranged on both sides of the waterproof part 141, and cooperates with the waterproof part 141 to guide the rain and fog to be discharged from the advertising screen in the vertical direction. It has a simple structure and good waterproof and dustproof effects.

[0048] Furthermore, the waterproof part 141 includes a water retaining strip 1411 fitted with the rear cover 2 and a water retaining groove 1412 provided between the housing 1 and the water retaining strip 1411, and the drainage part 142 includes a water guiding strip 1421 fitted with the rear cover 2 and a drainage groove 1422 provided between the housing 1 and the water guiding strip 1421. In this embodiment, the water retaining groove 1412 and the water retaining strip 1411 are integrally formed with the housing 1, the drainage groove 1422 and the water guiding strip 142 are integrally formed with the housing 1, and the water retaining strip 1411 and the water guiding strip 142 can fit with the rear cover 2, further enhancing the sealing of the box.

[0049] Furthermore, the outer frame 12 includes an upper frame 121, a left frame 122, a lower frame 123 and a right frame 124 which are connected end to end in sequence, the upper frame 121 and the lower frame 123 are both provided with a waterproof portion 141, the left frame 122 and the right frame 124 are both provided with a drainage portion 142, the water retaining groove 1412 on the upper frame 121 is open upward, the water retaining groove 1412 on the lower frame 123 is open downward, the drainage groove 1422 on the left frame 122 is open to the left, and the drainage groove 1422 on the right frame 124 is open to the right. Water mist enters the gap between the outer shell 1 and the back cover 2 after they are closed, that is, enters the waterproof part 141 of the upper frame 121, and accumulates on the water retaining groove 1412, and then flows along the drainage parts 142 of the left frame 122 and the right frame 124 to the waterproof part 141 of the lower frame 123, and flows out of the advertising screen along the gap between the outer shell 1 and the back cover 2 after they are closed relative to the waterproof part 141 of the lower frame 123, thereby effectively preventing water mist from entering the advertising screen through the gap between the outer shell 1 and the back cover 2 after they are closed, providing a safer use environment for the advertising screen and internal circuits.

[0050] Furthermore, the four ends of the rear cover 2 are all provided with water retaining guide strips 221, the water retaining guide strip 221 at the upper end of the rear cover 2 extends along the direction of the water retaining groove 1412 of the upper frame 121, the water retaining guide strip 221 at the lower end of the rear cover 2 extends along the direction of the water retaining groove 1412 of the lower frame 123, the water retaining guide strip 221 at the left end of the rear cover 2 extends along the direction of the drainage groove 1422 of the left frame 122, and the water retaining guide strip 221 at the right end of the rear cover 2 extends along the direction of the drainage groove 1422 of the right frame 124. It is beneficial to guide and discharge rain and fog, and further enhance the waterproof and dustproof effect of the advertising screen.

[0051] Furthermore, a sealing waterproof strip is provided between the housing 1 and the back cover 2. The gap between the housing 1 and the back cover 2 is further sealed to reduce water mist from entering the waterproof drainage structure 14 through the gap, thereby achieving a better waterproof effect.
