Double-screen liquid crystal display module

Abstract

This invention discloses a dual-screen liquid crystal display module, relating to the field of liquid crystal display technology. The actuating component includes a support block fixed inside a bracket. An electric push rod is installed at the bottom of the support block, and a connecting block is fixed to the extension end of the electric push rod. A rotating plate is fixedly connected to the bottom of the connecting block, and two symmetrical actuating components are fixed on the rotating plate. When the electric push rod is activated, its extension end precisely pushes the connecting block, causing the rotating plate to descend. When the rotating plate descends, the actuating plate at the top also descends, coming into contact with the relatively stationary air inside the bracket, generating a downward force on the air, causing some air to flow downward, breaking up air stratification, and promoting uniform temperature distribution. When the electric push rod retracts, it causes the connecting block and the rotating plate to rise. The two upward-moving actuating plates forcefully actuate the air, causing it to move upward. Repeated actuation allows heat inside the bracket to flow out quickly from the heat dissipation vents, effectively improving heat dissipation efficiency.

Description

Technical Field

[0001] This invention relates to the field of liquid crystal display technology, and in particular to a dual-screen liquid crystal display module. Background Technology

[0002] A liquid crystal display (LCD) screen is a flat-panel display device that works by using liquid crystal materials to change the propagation characteristics of light under the influence of an electric field to display images. It mainly consists of a backlight, a liquid crystal panel, and a driving circuit: the backlight provides light to the liquid crystal panel, while the driving circuit controls the voltage to adjust the alignment of the liquid crystal molecules, thereby controlling the propagation of light and ultimately achieving image display.

[0003] To meet display requirements from different angles, those skilled in the art have arranged two liquid crystal displays (LCDs) facing away from each other, thus forming a double-sided LCD display. Currently, double-sided LCDs are gradually gaining popularity in advertising, public transportation, and information display fields. With continuous technological advancements and gradual cost reductions, market demand continues to expand, and they are expected to be applied to more scenarios in the future, driving display technology towards greater efficiency and intelligence.

[0004] However, existing heat dissipation structures for double-sided LCD displays have certain problems. Their main heat dissipation method involves embedding a heat sink between the two metal backplates, using the heat sink to diffuse heat laterally, and then concentrating heat dissipation through the top cover of the bezel. This method relies primarily on airflow to dissipate heat from the top cover of the bezel into the air. However, when the temperature difference between the air and the heat dissipation components such as the bezel is small, the heat dissipation effect deteriorates, causing the heat from the double-sided LCD display to be unable to be effectively dissipated, thus affecting its overall heat dissipation performance. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of heat dissipation in existing double-sided LCD displays, which mainly involves embedding a heat sink between the metal backplates of the two screens. The heat sink diffuses heat laterally, and then the heat is concentrated through the top cover of the bezel. This heat dissipation method mainly dissipates the heat in the top cover of the bezel into the air through airflow. When the temperature difference between the air and the heat dissipation components such as the bezel is small, the heat dissipation effect is poor, resulting in the inability to effectively dissipate heat from the double-sided LCD display, thus affecting the heat dissipation effect of the double-sided LCD display. Therefore, this invention proposes a double-screen LCD display module.

[0006] To achieve the above objectives, the present invention employs the following technology: a dual-screen liquid crystal display module including a bracket and a display module and a power module connected within the bracket, and further including: a toggle component and an adjustment component disposed within the bracket; The actuating assembly includes a support block fixed in the bracket, an electric push rod installed at the bottom of the support block, a connecting block fixed at the extended end of the electric push rod, a rotating plate fixedly connected to the bottom of the connecting block, and two symmetrical actuating components fixed on the rotating plate. The electric push rod starts and extends downward, pushing the connecting block and rotating plate down. The actuating element on the rotating plate moves downward, agitating the air inside the bracket. When the electric push rod retracts upward, it pulls the connecting block and rotating plate. As the actuating element rises, it agitates the heat inside the bracket, causing it to move upward rapidly.

[0007] As a further description of the dual-screen LCD display module of the above technology: The actuating component includes a fixed frame fixed to the rotating plate, and an actuating plate is fixedly installed between the inner walls of the fixed frame.

[0008] As a further description of the dual-screen LCD display module of the above technology: The adjustment assembly includes two fixed rods fixed inside the bracket, and a closing plate is slidably connected to the outer periphery of the two fixed rods.

[0009] As a further description of the dual-screen LCD display module of the above technology: Each of the fixed rods is fitted with a telescopic spring on its outer periphery, and a connecting rope connects the bottom of the closed plate to the top of the connecting block.

[0010] As a further description of the dual-screen LCD display module of the above technology: The support block is fixed with connecting blocks on both sides, and the connecting blocks have slots and openings inside, and vents are opened through the connecting blocks.

[0011] As a further description of the dual-screen LCD display module of the above technology: The inner wall of the slot is slidably connected with a sliding block, and the sliding block and the connecting block are connected by a welding plate. The inner wall of the opening is threadedly connected with a threaded sealing plug.

[0012] As a further description of the dual-screen LCD display module of the above technology: The connecting block has two grooves inside, and a central column is fixed to the inner wall of each groove. A sealing plate that seals the vent is rotatably connected to the outer periphery of the central column. A connecting pipe for the tilt display module is connected to one side of the groove.

[0013] As a further description of the dual-screen LCD display module of the above technology: An air inlet is provided on one side of the bracket, and two symmetrical heat dissipation vents are provided on the top of the bracket.

[0014] In summary, due to the adoption of the above-mentioned technology in a dual-screen LCD display module, the beneficial effects of this invention are: By using the set toggle and adjustment components, the electric push rod is activated, and its extension end precisely pushes the connecting block, causing the rotating plate to descend. When the rotating plate descends, the top toggle plate also descends, coming into contact with the relatively still air inside the bracket, generating a downward force on the air, causing some of the air to flow downward, breaking up the air stratification, and promoting uniform temperature distribution. When the electric push rod retracts, it causes the connecting block and rotating plate to rise, and the two upward-moving toggle plates forcefully toggle the air, causing the air to move upward. Repeated toggle allows the heat inside the bracket to flow out quickly from the heat dissipation vents, effectively improving the heat dissipation efficiency. When the electric push rod extends and descends, it moves the connecting block downwards. Through the connecting rope, it applies a downward pulling force to the sealing plate that slides around the two fixed rods. The sealing plate slides along the fixed rods and stretches the telescopic spring until it precisely covers and seals the heat dissipation vent. In daily environments, there is a lot of dust. If the heat dissipation vent is open, dust can easily enter the bracket when the plate is moved and the air is stirred up. It will adhere to the surface of the equipment and affect heat dissipation. If it enters the inside of the components, it may cause short circuits and shorten the lifespan. The sealing plate can block dust and provide a clean working environment by sealing the heat dissipation vent. When the electric push rod retracts, it moves the connecting block upwards, reducing the tension of the connecting rope on the sealing plate. The previously stretched telescopic spring then rebounds, pulling the sealing plate upwards along the fixed rod, releasing the seal on the heat dissipation vents. At this time, the horizontal agitator moves upwards, dispersing air, causing heat to accumulate and the vents to open, allowing heat to escape smoothly. This design achieves a balance between dust prevention and heat dissipation, ensuring stable equipment operation. Start the electric push rod to extend and descend. The descent of the electric push rod will simultaneously drive the connecting block and welding plate to descend. During the descent of the welding plate, the sliding block will slide in the slot. Since the slot is closed at this time, as the sliding block descends, the closed plate on the right side will be pulled by the sliding block and rotate around the central column, thereby opening the vent. At this time, the heat in the upper part of the bracket will enter the slot through the open vent, while the sealing plate on the left will close the vent on the left as the sliding block descends. When a certain amount of heat accumulates in the slot, the electric push rod will rise, driving the sliding block to rise along with the welding plate. During the rising process, the sliding block will push the heat in the slot. At this time, the heat will push the right-side sealing plate to rotate around the central column, thereby sealing the vent. The left-side sealing plate will open under the push of the heat, allowing the heat to enter the connecting pipe through the open vent on the left. Subsequently, the heat will flow along the connecting pipe to blow and heat the display module, thereby effectively preventing water vapor from appearing on the display module.

[0017] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a dual-screen liquid crystal display module according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-9As shown, the present invention provides a dual-screen liquid crystal display module: including a bracket 11 and a display module 12 and a power module 13 connected in the bracket 11. An air inlet 14 is provided on one side of the bracket 11, and two symmetrical heat dissipation vents 15 are provided on the top of the bracket 11. It also includes a toggle component 20 and an adjustment component 30 disposed in the bracket 11. When heat dissipation is required for the display module 12 and the power module 13, outside air flows into the bracket 11 through the air inlet 14 and enters the area between the two display modules 12. Subsequently, the heat generated inside the bracket 11 will accumulate at its top and finally be discharged through the heat dissipation vent 15. Through this process, effective heat dissipation of the display module 12 and the power module 13 can be achieved, preventing the internal temperature of the bracket 11 from becoming too high.

[0019] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the actuating assembly 20 includes a support block 21 fixed in the bracket 11. An electric push rod 22 is installed at the bottom of the support block 21, and a connecting block 23 is fixed at the extended end of the electric push rod 22. A rotating plate 24 is fixedly connected to the bottom of the connecting block 23, and two symmetrical actuating elements are fixed on the rotating plate 24. The actuating elements include a fixing frame 25 fixed on the rotating plate 24, and an actuating plate 251 is fixedly installed between the inner walls of the fixing frame 25. However, in practical applications, when the temperature difference between the outside air and the internal heat of the bracket 11 is small, a tricky problem arises: the heat inside the bracket 11 cannot be discharged from the heat dissipation vent 15 in a timely and effective manner. This is because the small temperature difference results in insufficient power for natural air convection, and the heat accumulates inside the bracket 11 and is difficult to dissipate. To solve this problem, the electric push rod 22 can be activated. As the electric push rod 22 extends, its extended end will precisely push the connecting block 23. After being pushed, the connecting block 23 will drive the rotating plate 24 connected to it and located below to descend together. As the rotating plate 24 descends, the actuating plate 251 fixed to the top of the rotating plate 24 also descends. During the descent, the actuating plate 251 inevitably comes into contact with the relatively still air inside the bracket 11. Since air has a certain resistance, when the two actuating plates 251 move downward with the descent of the rotating plate 24, they will exert a downward force on the air inside the bracket 11, causing some air to flow downward. This downward flow of air helps to break the original air stratification phenomenon inside the bracket 11 and promotes the uniform temperature distribution of the air inside the bracket 11. When the electric push rod 22 retracts after completing its extension, it drives the connecting block 23 to move upward. As the connecting block 23 moves upward, it drives the rotating plate 24 at the bottom to rise as well. As the rotating plate 24 rises, the actuating plate 251 is again subjected to air resistance, which forcefully actuates the air inside the bracket 11. When the air comes into contact with the surface of the actuating plate 251, it is pushed upward by the actuating plate 251. By repeatedly performing this actuating action by the actuating plate 251, the heat inside the bracket 11 can flow out from the heat dissipation vent 15 more quickly, effectively improving the heat dissipation efficiency.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 As shown, the adjustment assembly 30 includes two fixed rods 31 fixed inside the bracket 11, and a closing plate 32 is slidably connected to the outer periphery of the two fixed rods 31. A telescopic spring 33 is sleeved on the outer periphery of each fixed rod 31, and a connecting rope 34 is connected between the bottom of the closing plate 32 and the top of the connecting block 23. Connecting blocks 35 are fixed on both sides of the support block 21, and the interior of the connecting block 35 has a slot 351 and an opening 354. A vent 359 is opened through the interior of the connecting block 35. A sliding block 352 is slidably connected to the inner wall of the slot 351. The sliding block 352 and the slot 351 are connected... A sealing ring is connected, and the sliding block 352 and the connecting block 23 are connected by a welding plate 353. The inner wall of the opening 354 is threaded with a threaded sealing plug 355. The threaded sealing plug 355 can be removed or closed through the heat dissipation port 15. When heat dissipation is required, the threaded sealing plug 355 is moved out of the opening 354. Two grooves 356 are opened inside the connecting block 35, and a central column 357 is fixed on the inner wall of each groove 356. The outer periphery of the central column 357 is rotatably connected to a sealing plate 358 that closes the vent 359. A connecting pipe 36 for the tilt display module 12 is connected to one side of the groove 356. At the same time, when the electric push rod 22 begins to extend and gradually descends, its extended end is tightly connected to the connecting block 23, which will drive the connecting block 23 to move downward synchronously. During the descent, the connecting block 23 applies a downward pulling force to the sealing plate 32 through the pre-connected connecting rope 34. The sealing plate 32 slides around the outer periphery of the two fixed rods 31. Under the action of the pulling force, the sealing plate 32 will slide smoothly along the outer periphery of the fixed rods 31 and stretch the telescopic spring 33. As the connecting rope 34 continues to move downward, the sealing plate 32 will accurately cover the heat dissipation vent 15 and completely seal the heat dissipation vent 15. This sealing operation is of great significance. In daily use, a large number of dust particles often float in the air. When the toggle plate 251 descends to perform internal air agitation and other operations, if the heat dissipation vent 15 is in an open state, these dust particles can easily enter the bracket 11 through the heat dissipation vent 15. Once the dust enters the bracket 11, it may adhere to the surface of the display module 12 and the power module 13, affecting their heat dissipation performance. It may also enter the electronic components, causing short circuits and other malfunctions, and shortening the service life of the equipment. The sealing plate 32 effectively blocks the entry of dust by sealing the heat dissipation vent 15, providing a relatively clean working environment for the equipment inside the bracket 11. When the electric push rod 22 retracts after completing its extension and descent, the situation changes. The electric push rod 22 drives the connecting block 23 to move upward. At this time, the tension of the connecting rope 34 on the sealing plate 32 gradually decreases, while the telescopic spring 33, which was originally in a stretched state, generates a rebound force due to its elasticity. Under the action of this rebound force, the telescopic spring 33 pulls the sealing plate 32 to slide upward along the fixed rod 31. As the sealing plate 32 moves, it gradually releases the seal on the heat dissipation port 15, and the heat dissipation port 15 returns to an open state. At this time, the horizontal agitator 251 effectively agitates the air inside the bracket 11 during its upward movement, causing heat to accumulate in the air. Since the heat dissipation port 15 has been opened, this agitated heat can flow smoothly out of the bracket 11 through the heat dissipation port 15. Through this design, while ensuring dust prevention inside the bracket 11, heat can be discharged in time when heat dissipation is needed, achieving a good balance between dust prevention and heat dissipation functions, and ensuring the stable operation of the entire equipment. When using dual LCD monitors in winter, special attention should be paid to their operating temperature range, which is usually from 0°C to 50°C. When the indoor temperature is too low, especially close to or below 0°C, water vapor will form on the monitor surface due to the temperature difference between the inside and outside. This water vapor will not only seriously affect the display effect, but may also cause potential damage to the internal circuitry of the monitor. To effectively address this problem, the following measures can be taken: Connect the threaded sealing plug 355 to the opening 354, then activate the electric push rod 22 to extend and descend. The descent of the electric push rod 22 will simultaneously drive the connecting block 23 and the welding plate 353 to descend. During the descent of the welding plate 353, it will cause the sliding block 352 to slide within the slot 351. Since the slot 351 is in a closed state at this time, as the sliding block 352 descends, as... Figure 9 As shown, the closed disc 358 on the right side will be pulled by the sliding block 352 and rotate around the central column 357, thereby opening the vent 359. At this time, the heat in the upper part of the bracket 11 will enter the slot 351 through the open vent 359, while the left sealing plate 358 will close the left vent 359 as the sliding block 352 descends. When a certain amount of heat accumulates in the slot 351, the electric push rod 22 will rise, driving the sliding block 352 to rise along with the welding plate 353. During the rising process, the sliding block 352 will push the heat in the slot 351. At this time, heat will push Figure 9 The right-side sealing plate 358 rotates around the central column 357, thereby sealing the vent 359. The left-side sealing plate 358 opens under the push of heat, allowing heat to enter the connecting pipe 36 through the open vent 359 on the left. Subsequently, the heat flows along the connecting pipe 36 to blow and heat the display module 12, thereby effectively preventing water vapor from appearing on the display module 12.

[0021] Working principle: However, in practical applications, when the temperature difference between the outside air and the heat inside the bracket 11 is small, a tricky situation will occur. Because the temperature difference is small, the natural convection force of the air is insufficient, and the heat inside the bracket 11 cannot be discharged from the heat dissipation vent 15 in a timely and effective manner, and it accumulates and is difficult to dissipate. To solve this problem, the electric push rod 22 can be activated. When the electric push rod 22 extends, its extended end precisely pushes the connecting block 23. The connecting block 23 drives the lower rotating plate 24 to descend together. As the rotating plate 24 descends, the top fixed actuating plate 251 also descends and comes into contact with the relatively still air inside the bracket 11, generating a downward force on the air inside the bracket 11, causing some air to flow downward, breaking the air stratification, and promoting uniform temperature distribution. When the electric push rod 22 completes its extension and retraction, it drives the connecting block 23 to move upward, which in turn drives the rotating plate 24 to rise. During the rise, the two upward-moving actuating plates 251 forcefully actuate the air inside the bracket 11, causing the air to be pushed upward. Repeated actuation can allow the heat inside the bracket 11 to flow out quickly from the heat dissipation port 15, thereby improving the heat dissipation efficiency. At the same time, when the electric push rod 22 extends and descends, its extended end drives the connecting block 23 to move down synchronously. The connecting block 23 applies a downward pulling force to the closing plate 32 that slides around the two fixed rods 31 through the connecting rope 34. The closing plate 32 slides along the fixed rods 31 and stretches the telescopic spring 33 until it precisely covers and seals the heat dissipation port 15. In daily environments, there is a lot of dust. If the heat dissipation port 15 is open, when the agitator plate 251 stirs the air, dust can easily enter the bracket 11, adhere to the surface of the equipment and affect heat dissipation. If it enters the inside of the components, it may also cause short circuits and shorten the lifespan. The closing plate 32 can block dust and provide a clean working environment by sealing the heat dissipation port 15. When the electric push rod 22 completes its extension and retraction, it drives the connecting block 23 to move upward. The tension of the connecting rope 34 on the sealing plate 32 decreases, and the originally stretched telescopic spring 33 generates a rebound force, pulling the sealing plate 32 to slide upward along the fixed rod 31, releasing the closure of the heat dissipation vent 15 and allowing it to reopen. At this time, the horizontal agitator plate 251 moves upward and agitates the air, causing heat to accumulate. The heat dissipation vent 15 opens, and the heat can flow out smoothly. This design achieves a balance between dust prevention and heat dissipation functions, ensuring stable operation of the equipment. When using dual LCD monitors in winter, special attention should be paid to their operating temperature range, which is usually from 0°C to 50°C. When the indoor temperature is too low, especially close to or below 0°C, water vapor will form on the monitor surface due to the temperature difference between the inside and outside. This water vapor will not only seriously affect the display effect, but may also cause potential damage to the internal circuitry of the monitor. To effectively address this problem, the following measures can be taken: Connect the threaded sealing plug 355 to the opening 354, then activate the electric push rod 22 to extend and descend. The descent of the electric push rod 22 will simultaneously drive the connecting block 23 and the welding plate 353 to descend. During the descent of the welding plate 353, the sliding block 352 will slide within the slot 351. Since the slot 351 is in a closed state at this time, as the sliding block 352 descends, the sealing disc 358 on the right side will be pulled by the sliding block 352 and rotate around the central column 357, thereby opening the vent 359. At this time, the heat in the upper part of the bracket 11 will enter the slot 351 through the open vent 359, while the left sealing plate 358 will close the left vent 359 as the sliding block 352 descends. When a certain amount of heat accumulates in the slot 351, the electric push rod 22 will rise, driving the sliding block 352 to rise along with the welding plate 353. During the rising process, the sliding block 352 will push the heat in the slot 351. At this time, the heat will push the right-side sealing plate 358 to rotate around the central column 357, thereby sealing the vent 359. Meanwhile, the left-side sealing plate 358 will open under the push of the heat, allowing the heat to enter the connecting pipe 36 through the open vent 359 on the left. Subsequently, the heat will flow along the connecting pipe 36 to blow and heat the display module 12, thereby effectively preventing water vapor from appearing on the display module 12.

[0022] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's technology and inventive concept, should be covered within the scope of protection of the present invention.
