[0035] An embodiment of the present utility model provides a waterproof outdoor advertising machine. Refer to Figures 1 to 5 , including:

[0036] A display module 1 for displaying information;

[0037] A waterproof bin 2, the display module 1 is detachably installed on the front of the waterproof bin 2; a main control board 4 electrically connected to the display module 1 is installed in the waterproof bin 2; a water guide groove 21 is provided along the circumferential direction on the outside of the waterproof bin 2;

[0038] A waterproof rear cover 3 covers the back of the waterproof bin 2, and the waterproof rear cover 3 is provided with a drainage baffle 31 docked with the water guide groove 21.

[0039] In this embodiment, the waterproof structure of the existing outdoor advertising machine is improved. The main control board 4 that is easily damaged after water ingress is installed in the waterproof bin 2 for protection. Among them, a water guide groove 21 is provided on the outside of the waterproof bin 2. When it rains, the rainwater will flow along the water guide groove 21, which can prevent it from entering the inside of the waterproof bin 2 and improve the waterproof performance; further, a waterproof rear cover 3 is covered on the outside of the waterproof bin 2 for double waterproofing. At the same time, a drainage baffle 31 is provided on the waterproof rear cover 3. After the rainwater falls on the waterproof rear cover 3, it will flow into the water guide groove 21 along the drainage baffle 31 and then be discharged by the water guide groove 21, thereby further improving the waterproof effect.

[0040] Furthermore, refer to Figure 4 and Figure 5 , a partition 22 is provided in the waterproof bin 2, and the partition 22 is used to divide the waterproof bin 2 into a waterproof front bin 23 and a waterproof rear bin 24. The display module 1 is detachably connected to the waterproof front bin 23, the main control board 4 is installed in the waterproof rear bin 24, and the waterproof rear cover 3 covers the outside of the waterproof rear bin 24.

[0041] In this embodiment, the waterproof chamber 2 is divided into a front waterproof chamber 23 and a rear waterproof chamber 24 by arranging a partition plate 22. The front waterproof chamber 23 is used to install the display module 1, and the rear waterproof chamber 24 is used to install the main control board 4. In this way, the display module 1 and the main control board 4 are installed in separate areas, and the heat generated by them is dissipated separately, without affecting each other, thereby improving the overall heat dissipation efficiency of the advertising machine. At the same time, the display module 1 is of a modular structure and has strong waterproof performance itself. Therefore, there is no need to use a waterproof cover plate for secondary waterproofing, which can simplify the waterproof structure and reduce the manufacturing cost of the advertising machine.

[0042] Further, referring to Figure 6 , the rear waterproof chamber 24 is arranged in a rectangular body structure, and the water guide groove 21 extends along the docking portion of the waterproof rear cover 3 and the rear waterproof chamber 24. In this embodiment, the shape of the rear waterproof chamber 24 is set based on the shape of the actual advertising machine. In the prior art, the common advertising machine is of a rectangular structure. Therefore, in this embodiment, the rear heat prevention chamber is arranged in a rectangular body structure as a whole to maintain the consistency of the overall appearance. The water guide groove 21 extends along the docking portion of the waterproof rear cover 3 and the rear waterproof chamber 24. When rainwater flows in from the gap between the waterproof rear cover 3 and the rear waterproof chamber 24, it can enter the water guide groove 21 and be discharged, without worrying about water entering the rear waterproof chamber 24 and affecting the use of the internal main control board 4. At the same time, the water guide groove 21 forms a rectangular ring groove structure along the side edge of the rear waterproof chamber 24. The water flow enters from above the water guide groove 21 and flows along the water guide groove 21 to the bottom of the advertising machine for discharge, ensuring smooth drainage.

[0043] Further, referring to Figure 7 , the drainage baffle 31 is located at the top of the waterproof rear cover 3, and the drainage baffle 31 is arranged at an inclination angle with the rear waterproof chamber 24. In this embodiment, the drainage baffle 31 is inclined. Along the direction of the water flow, the included angle between it and the rear waterproof chamber 24 gradually decreases, forming a conical inlet with a large opening for rainwater to enter, which can quickly divert the rainwater into the water guide groove 21 for discharge, further improving the waterproof performance.

[0044] Further, two mounting ears 32 are symmetrically arranged on the edge of the waterproof rear cover 3, and a plurality of first screw through holes 33 are opened on the mounting ears 32. First screw holes 25 corresponding to the first screw through holes 33 are opened on the rear waterproof chamber 24. During installation, the mounting ears 32 of the waterproof rear cover 3 are fitted with the rear waterproof chamber 24. At this time, the first screw through holes 33 and the first screw holes 25 correspond one by one, and are locked with screws to complete the installation of the waterproof rear cover 3, ensuring stable structural installation and facilitating later disassembly.

[0045] Further, a plurality of first support columns 26 are provided in the waterproof rear compartment 24, and the main control board 4 is mounted on the first support columns 26. In this embodiment, the main control board 4 is mounted in the waterproof rear compartment 24 through the first support columns 26, which can increase its contact area with the air, accelerate the air flow around it, and improve the heat dissipation efficiency.

[0046] Further, a cooling fan 5 is installed in the waterproof rear compartment 24. A through hole 27 corresponding to the cooling fan 5 is formed in the partition plate 22, and a plurality of heat dissipation holes 28 are formed in the side wall of the waterproof rear compartment 24.

[0047] Further, referring to Figure 3 , the display module 1 includes a fixing frame 11 detachably connected to the waterproof front compartment 23. A display screen 12 is installed in the fixing frame 11. A glass cover plate 13 is provided on the light-emitting side of the display screen 12, and the glass cover plate 13 is fixedly connected to the fixing frame 11. In this embodiment, by adding the glass cover plate 13 on the light-emitting side of the display screen 12, the display screen 12 can be effectively protected, its service life can be extended, and it can be prevented from being damaged by external forces. The display screen 12 and the glass cover plate 13 are installed in the fixing frame 11 together to form a whole, which is convenient for the assembly of the advertising machine.

[0048] Further, a sealing ring 14 is also abutted between the fixing frame 11 and the waterproof front compartment 23. In this embodiment, by adding the sealing ring 14 between the fixing frame 11 and the waterproof front compartment 23, the sealing performance between the connection structures can be improved, and rainwater can be prevented from entering the waterproof front compartment 23, affecting the normal use of the advertising machine.

[0049] Further, a plurality of second support columns 29 are also provided in the waterproof front compartment 23, and the ends of the second support columns 29 are abutted against the backlight side of the display screen 12. In this embodiment, the display screen 12 is abutted against the ends of the second support columns 29 and does not fit against the inner side of the waterproof front compartment 23, which can increase the contact area of the display screen 12 with the air, accelerate the air flow around it, and improve the heat dissipation efficiency of the display screen 12.

[0050] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
