[0002] Existing advertising machines usually include a housing and an LCM display module arranged in the housing. The housing usually includes a plastic back panel. When installing, the LCM display module is first installed in the back panel, and then the back panel is installed. When working, since the LCM display module generates a large amount of heat, a corresponding heat dissipation device (such as a heat dissipation fan) is also installed in the housing to dissipate heat. Some people also change the back panel to an aluminum back panel, and then directly install a heat conduction block between the LCM display module and the aluminum back panel to conduct heat, so as to quickly discharge the heat to the outside. Both of these heat dissipation methods are inconvenient to install and have the disadvantage of a large thickness of the advertising machine.

[0028] The following will provide a clear and complete description of the technical solutions in the present embodiment of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only preferred embodiments of the present invention.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] See attached Figures 1 to 7 In the embodiment of the utility model, an ultra-thin advertising machine with easy heat dissipation includes a frame 10, a protective glass 20, and a back plate 30. The protective glass 20 is installed and connected to the front side of the frame 10, and the back plate 30 is connected to the rear side of the frame 10. The frame 10, the protective glass 20, and the back plate 30 are surrounded to form an installation cavity for installing a display module;

[0032] The display module includes a display glass 41, a liquid crystal 42, and a backlight panel 43; the backlight panel 43 includes a circuit board 431 and a plurality of lamp beads 432 installed on the front side of the circuit board 431; the rear side of the backlight panel 43 is attached to the front side of the back panel 30, the back panel 30 is made of aluminum alloy, and the rear side of the back panel 30 is exposed to the outside.

[0033] In this way, the circuit board 431 of the backlight panel 43 is directly attached to the back panel 30, and the back panel 30 is used as the back panel 30 of the advertising machine to directly contact the outside world as a heat sink. Compared with the traditional technology, the plastic back panel 30 is omitted, so that the product can be made thinner; at the same time, aluminum alloy is used as the material of the back panel 30 of the advertising machine, and the backlight panel 43 is attached to the front side of the back panel 30, thereby effectively improving the heat dissipation efficiency of the advertising machine.

[0034] Preferably, the rear side of the back plate 30 is provided with heat dissipation fins 31; the heat dissipation fins 31 are arranged at intervals in the left-right direction, and the plurality of heat dissipation fins 31 form a plurality of heat dissipation air ducts extending in the up-down direction; the heat dissipation fins 31 and the back plate 30 are preferably integrally formed. Furthermore, a control box 50 is installed on the rear side of the back plate 30, and a heat dissipation fan 51 is installed on the control box 50; the heat dissipation fan 51 is obliquely arranged on the rear side of the back plate 30, and is arranged to blow air toward the heat dissipation air duct. In this way, by providing the heat dissipation fins 31, the heat dissipation area is increased; at the same time, by obliquely arranging the heat dissipation fan 51, the wind speed is increased. Compared with the straight-on setting, the oblique setting reduces the amount of wind that is blocked by the back plate in the positive direction of the return flow, that is, the heat dissipation efficiency is improved. The heat dissipation fan 51 is arranged in plurality in the left-right direction.

[0035] The control box 50 is in contact with the rear side of the heat sink fin 31, that is, the installation of the control box 50 will not block the heat dissipation duct, and the heat dissipation duct is located at the front side of the control box 50, which can also drive the heat dissipation of the control box 50; in actual application, the backlight panel 43 is a dynamic backlight panel, that is, compared with the traditional LCM module, it can control the opening and closing, brightness and darkness of different numbers of lamp beads 432 in real time, which is more energy-saving and has better display effect; the control box 50 is provided with a control module for controlling the lamp beads 432, and the control module and the backlight panel 43 are usually connected by wires. The circuit board 431 is usually made of an aluminum substrate, which has a better heat dissipation effect than a fiberglass board.

[0036] Furthermore, the front side of the display glass 41 is attached to the rear side of the protective glass 20; thus, by attaching the display glass 41 to the rear side of the protective glass 20, compared with the existing advertising machine that keeps a certain distance between the display glass 41 and the protective glass 20, the refraction distance of light is reduced, the display effect of the advertising machine is further improved, and the impact of poor visual effects caused by refracted polarized light is reduced.

[0037] Furthermore, the frame 10 has a front mounting recess 11 for mounting the protective glass 20 and a rear mounting recess 12 for mounting the back plate 30, thereby ensuring a better waterproof effect. Preferably, a sealing structure is provided between the frame 10 and the protective glass 20, and similarly, a sealing structure is provided between the back plate 30 and the frame 10, and the sealing structure may be a sealant (water), thereby ensuring the airtightness inside the advertising machine; it should be supplemented that the back plate 30 and the frame 10 are usually fixed by connecting screws. The frame 10 is usually made of aluminum profiles.

[0038] Preferably, thermally conductive silicone is coated between the backlight panel 43 and the back panel 30 to further improve the thermal conductivity effect.

[0039] The design focus of the utility model is that it mainly reduces the thickness of the advertising machine by directly attaching the backlight plate to the aluminum back plate, while also improving the heat dissipation efficiency of the advertising machine; secondly, through the specific design of the heat dissipation fins, the heat dissipation fan and the control box, the heat dissipation effect of the advertising machine is further improved;

[0040] Furthermore, by bonding the display glass to the protective glass, the display effect of the advertising machine is further improved.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
