[0001] The utility model relates to the field of liquid crystal display screens, in particular to a waterproof liquid crystal display screen for outdoor use. Background Art

[0002] Liquid crystal displays (LCDs) are a widely used display technology, widely used in various devices due to their thinness, low power consumption, and radiation-free nature. Outdoor waterproof LCDs are specialized displays designed for outdoor environments, capable of functioning in a variety of harsh weather conditions, including rain, snow, high and low temperatures. These displays are widely used in billboards, public transportation displays, live sports broadcasts, and outdoor digital signage.

[0003] Currently available waterproof LCD screens for outdoor use usually have a housing installed outside the LCD module and a sealing strip installed at the connection between the LCD module and the housing. The sealing strip seals the connection between the LCD module and the housing to prevent rainwater from entering the interior through the gap between the LCD module and the housing. However, the sealing strip is prone to aging after long-term outdoor use. Rainwater remaining between the lower part of the LCD module and the housing will pass through the aged sealing strip and enter the housing, affecting the normal use of the LCD module.

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0025] A waterproof LCD display for outdoor use, such as Figures 1-9 As shown, it includes a shell 1, a placement plate 101, a back plate 2, a liquid crystal display module 4, a cooling plate 401, a sealing strip 5, a water-absorbing cotton 6, a collection frame 7, a collection tube 8 and a liquid storage tank 9. The placement plates 101 are symmetrically connected to the front and back of the shell 1. The back side of the shell 1 is connected to the back plate 2. The liquid crystal display module 4 is placed between the placement plates 101. The liquid crystal display module 4 is located between the shell 1 and the back plate 2. The lower side of the liquid crystal display module 4 is connected to the cooling plate 401. The left and right sides and the upper side of the liquid crystal display module 4 are connected to the outer A sealing strip 5 is provided between the shells 1, a collecting frame 7 is connected to the front lower part of the shell 1, and absorbent cotton 6 is connected to the collecting frame 7. The absorbent cotton 6 is located between the lower part of the LCD screen and the shell 1. A liquid storage tank 9 is connected to the bottom of the shell 1, and a collection pipe 8 is connected between the liquid storage tank 9 and the collecting frame 7. When it rains, the absorbent cotton 6 between the lower part of the LCD module 4 and the shell 1 absorbs rainwater, and the rainwater in the absorbent cotton 6 falls into the collecting frame 7 by gravity and is transported to the liquid storage tank 9 through the collecting pipe 8 for storage;

[0026] The housing 1 further includes a breathable plate 3 connected to the rear side of the lower portion thereof for allowing air to circulate between the interior of the housing 1 and the outside air, thereby dissipating heat from the liquid crystal display module 4.

[0027] The overflow port 901 and the overflow cover 10 are also included. The overflow port 901 is provided on the upper part of the liquid storage tank 9. The overflow cover 10 is rotatably connected to the liquid storage tank 9. The overflow cover 10 is used to block the overflow port 901 to prevent external impurities from contaminating the water in the liquid storage tank 9. When the water level in the liquid storage tank 9 reaches the overflow port 901, the overflow cover 10 is driven to rotate and open under the action of water pressure. At this time, the water in the liquid storage tank 9 can be discharged through the overflow port 901, preventing the water in the collection pipe 8 and the collection frame 7 from flowing back due to the high water level. After the water level drops below the overflow port 901, the overflow cover 10 rotates and resets under the action of gravity to block the overflow port 901 again.

[0028] The cooling plate 401 further includes an air-cooling fin 11 and a fan 12. The cooling plate 401 is connected to the lower side of the cooling fin 11. The left and right sides of the lower portion of the housing 1 are connected to the fans 12. The fans 12 are located at both ends of the cooling fin 11. The heat generated by the liquid crystal display module 4 is transferred to the cooling fin 11 through the cooling plate 401. The fan 12 rotates to accelerate the air flow speed, cooling the cooling fin 11, thereby improving the heat dissipation speed of the liquid crystal display module 4.

[0029] The housing 1 further includes an electric push rod 13, a water-cooling box 14, and a water-cooling fin 1401. The electric push rod 13 is symmetrically connected to the bottom of the housing 1. The telescopic ends of the electric push rod 13 are connected to the water-cooling box 14, and the water-cooling fins 1401 are connected to the water-cooling box 14. When dissipating heat, the telescopic ends of the electric push rod 13 drive the water-cooling box 14 and the water-cooling fins 1401 to move upward, so that the water-cooling fins 1401 contact the air-cooling fins 11. Under the action of the water-cooling box 14 and the water-cooling fins 1401, the liquid crystal display module 4 is water-cooled and dissipated, thereby further improving the heat dissipation speed of the liquid crystal display module 4.

[0030] It also includes a circulation component 15. The water cooling box 14 is connected to the liquid storage tank 9 by a circulation component 15. The circulation component 15 can drive the water in the water cooling box 14 and the water in the liquid storage tank 9 to circulate, thereby ensuring the water cooling and heat dissipation effect.

[0031] When the present invention is in use, it needs to be installed in the operating area. When it rains, the absorbent cotton 6 between the lower part of the liquid crystal display module 4 and the shell 1 absorbs rainwater, and the rainwater in the absorbent cotton 6 falls into the collection frame 7 by gravity and is transported to the liquid storage tank 9 for storage through the collection pipe 8. The overflow cover 10 is used to block the overflow port 901 to prevent external impurities from contaminating the water in the liquid storage tank 9. When the water level in the liquid storage tank 9 reaches the overflow port 901 position, the overflow cover 10 is driven to rotate and open under the action of water pressure. At this time, the water in the liquid storage tank 9 can be discharged through the overflow port 901 to prevent the water in the collection pipe 8 and the collection frame 7 from flowing back due to the high water level. After the water level drops below the overflow port 901, the overflow cover 10 rotates and resets under the action of gravity to block the overflow port 901 again. When used outdoors, a large amount of heat is generated, so the liquid crystal display module 4 needs to be cooled. That is, the heat generated by the liquid crystal display module 4 is transferred to the air-cooling fins 11 through the cooling plate 401, and then the air flow speed is accelerated by the rotation of the fan 12 to cool the air-cooling fins 11, thereby improving the heat dissipation speed of the liquid crystal display module 4. At the same time, the telescopic end of the electric push rod 13 drives the water-cooling box 14 and the water-cooling fins 1401 to move upward, so that the water-cooling fins 1401 contact the air-cooling fins 11. Under the action of the water-cooling box 14 and the water-cooling fins 1401, the liquid crystal display module 4 is water-cooled, thereby further improving the heat dissipation speed of the liquid crystal display module 4. The circulation component 15 can drive the water in the water-cooling box 14 and the water in the liquid storage tank 9 to circulate, thereby ensuring the water-cooling heat dissipation effect.

Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
