Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example 1: Figure 1-Figure 6As shown, a liquid crystal display module with a protective structure includes a backlight module 18 with a screen panel 1 installed on one side. The screen panel 1 and the backlight module 18 are accompanied by a main control board, a circuit board and other components, which can be used for image display and color adjustment. A heat conducting plate 19 and a fan bracket 20 are fixedly connected to one side of the backlight module 18. Both sides of the fan bracket 20 are fixedly connected to semiconductor refrigeration plates 13. The principle of the semiconductor refrigeration plate 13 is based on the Peltier effect. When current passes through an N / P type semiconductor, one end absorbs heat at a cold end and the other end releases heat at a hot end. The cooling side of the semiconductor refrigeration plate 13 is fixedly connected to the heat conducting plate 19. One side of the fan bracket 20 is fixedly connected to a plurality of fans 21.

[0030] When in use, the semiconductor refrigeration plate 13 can cool the backlight module 18 through multiple horizontally installed heat conducting plates 19. At the same time, the middle part of the fan bracket 20 is inclined, and multiple fans 21 installed on the top can blow air to one side of the semiconductor refrigeration plate 13. Such flowing air can make the cooling more uniform, and at the same time, the low-temperature air can flow to other parts of the entire display module to cool the entire display module.

[0031] The rear side of the fan bracket 20 is fixedly connected with a guide baffle 17, and one side of the guide baffle 17 and the fan bracket 20 is provided with an air inlet slot 12, and a filter cotton 16 is fixedly connected inside the air inlet slot 12.

[0033] In this embodiment, the screen panel 1 and the backlight module 18 are fixedly connected to the outer side with an inner bracket 11, the outer side of the inner bracket 11 is slidably connected to the outer bracket 2, and the air inlet slots 12 are opened on both sides of the outer bracket 2. The inner bracket 11 can protect components such as the screen panel 1 and the backlight module 18. At the same time, there is an electrostatic shielding layer inside the inner bracket 11, which can be used for electromagnetic interference protection.

[0034] In this embodiment, a plurality of buffer platforms 14 and springs 15 are fixedly connected to the inner wall of the rear side of the outer bracket 2, and the other end of the spring 15 is fixedly connected to the rear side of the inner bracket 11;

[0035] When the screen panel 1 is impacted, it can slide inward to reduce the damage to the screen panel 1 caused by the impact. The buffer platform 14 is preferably made of sponge material, which can have a buffering effect, and the spring 2 15 can allow the screen panel 1 to reset against the outer inner wall of the outer bracket 2. At the same time, the outer inner wall of the outer bracket 2 is affixed with a sponge strip to prevent impact damage to the screen panel 1.

[0036] In this embodiment: when in use, the semiconductor refrigeration plate 13 can cool the backlight module 18 through multiple horizontally installed heat conducting plates 19, and the middle part of the fan bracket 20 is inclined, and multiple fans 21 installed on the top can blow air to one side of the semiconductor refrigeration plate 13, so that the flowing air can make the cooling more uniform, and at the same time, the low-temperature air can flow to other parts of the entire display module to cool the whole;

[0037] The guide baffle 17 can ensure the flatness of the rear side of the device, making it easy to install and fix;

[0038] The filter cotton 16 can filter dust in the intake air, and the inner bracket 11 can protect the screen panel 1 and the backlight module 18 and other components. At the same time, there is an electrostatic shielding layer inside the inner bracket 11, which can be used for electromagnetic interference protection;

[0039] When the screen panel 1 is impacted, it can slide inward to reduce the damage to the screen panel 1 caused by the impact. The buffer platform 14 is preferably made of sponge material, which can have a buffering effect, and the spring 2 15 can allow the screen panel 1 to reset against the outer inner wall of the outer bracket 2. At the same time, the outer inner wall of the outer bracket 2 is affixed with a sponge strip to prevent impact damage to the screen panel 1.

[0040] Embodiment 2: A liquid crystal display module with a protective structure. This embodiment makes the following improvements on the basis of Embodiment 1: Figure 1-Figure 6 As shown,

[0041] In this embodiment, the outer bracket 2 is fixedly connected with a plurality of thermally conductive silicone rubbers 6, and the outer bracket 2 is rotatably connected with a plurality of buffer racks 7; the thermally conductive silicone rubber 6 can better transfer heat between the buffer racks 7 and the outer bracket 2, thereby reducing heat accumulation.

[0042] In this embodiment, a plurality of buffer guard plates 1 3 and buffer guard plates 2 4 are slidably connected to the side of the outer bracket 2, and the buffer guard plates 1 3 and buffer guard plates 2 4 are symmetrically installed on both sides of the outer bracket 2. The inner walls of the buffer guard plates 1 3 and buffer guard plates 2 4 are respectively rotatably connected to one end of the buffer frame 7 on the corresponding side; when the buffer guard plates 1 3 and buffer guard plates 2 4 are subjected to lateral external impact, they will shrink inward under the action of the buffer frame 7 and then rebound, so as to prevent the external impact from directly acting on the outer bracket 2 and then causing damage to the screen panel 1;

[0043] The buffer frame 7 includes an aluminum plate 8, a rotating shaft 9 and a spring 10. The two aluminum plates 8 are rotatably connected to each other. The lower aluminum plate 8 is rotatably connected to the outer bracket 2, and the upper aluminum plate 8 is rotatably connected to the buffer guard plate 1 3 or the buffer guard plate 2 4. The rotating shaft 9 is fixedly connected to the upper aluminum plate 8, and the spring 10 is fixedly connected to the rotating shaft 9 and the lower aluminum plate 8.

[0044] The angle between the two aluminum plates 8 is limited by a spring 10. When the outer buffer guard plate 1 3 or the buffer guard plate 2 4 is impacted, the angle between the two aluminum plates 8 becomes smaller, and the spring 10 is compressed to provide buffering. At the same time, the aluminum plates 8 cooperate with the thermal conductive silicone 6 to facilitate heat transfer and heat dissipation.

[0045] In this embodiment, the outer bracket 2, the buffer guard plate 2 4 and the thermal conductive silicone 6 are respectively provided with an air outlet slot 5 on one side. The air outlet slot 5 is perpendicular to the air inlet slot 12 and can spray air from the other two sides to form an air duct. At the same time, the gas can cool the edge of the screen panel 1 during the flow process.

[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
