Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal screen heat dissipation, and in particular to a high-efficiency heat dissipation liquid crystal screen. Background Art

[0002] Liquid crystal displays (LCDs), a common display device, display images through the arrangement of liquid crystal molecules. They are widely used in televisions, computer monitors, outdoor advertising screens, and many other fields. During operation, the electronic components within the LCD continuously generate heat. This heat accumulation, especially during prolonged high-load operation or in high ambient temperatures, can affect the display quality and lifespan. Therefore, heat dissipation performance is a key indicator of LCD screen quality.

[0003] Currently, LCD screens on the market usually use cooling fans to assist in heat dissipation, but the existing technology has some shortcomings: Most cooling fans are installed at a fixed angle and can only dissipate heat in specific areas of the LCD screen. The heat dissipation range is limited and it is difficult to cover the entire screen, resulting in uneven temperatures in different areas of the LCD screen. Some high-temperature areas still have the risk of performance damage.

[0004] At the same time, to ensure air circulation during heat dissipation, the LCD screen's mounting structure is generally equipped with air intakes and exhaust ports, but the diameter of these openings cannot be adjusted. When heat dissipation is not required, dust and impurities from the outside can easily enter the device through the air intake and exhaust ports, attaching to electronic components and affecting heat dissipation efficiency and device life. When heat dissipation is required, the air flow cannot be controlled by adjusting the size of the openings, making it difficult to optimize the heat dissipation effect according to actual heat dissipation needs. In addition, the fan and air intake and exhaust systems in the existing heat dissipation structure lack linkage, making it impossible to synergistically improve heat dissipation efficiency. The overall heat dissipation performance needs to be further improved. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides a high-efficiency heat dissipation LCD screen, which overcomes the shortcomings of the existing technology and effectively solves the problems of limited heat dissipation range of the cooling fan, inability to adjust the air inlet and exhaust port, and difficulty in balancing heat dissipation and dust prevention.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A high-efficiency heat-dissipating liquid crystal display comprises a mounting bracket mounted on the inner wall of a wall, a servo motor being fixedly connected to the top outer wall of the mounting bracket via screws, and a vertical reciprocating screw being fixedly connected to the output shaft of the servo motor via a coupling, a first threaded sleeve being screwed onto the outer wall of the vertical reciprocating screw, and a gear being rotatably connected to the outer wall of one side of the first threaded sleeve, a rack being meshed on the outer wall of the gear, a transverse reciprocating screw being fixedly connected to the outer wall of one side of the gear, and a second threaded sleeve being screwed onto the outer wall of the transverse reciprocating screw, and a heat dissipating fan being fixedly connected to the top outer wall of the second threaded sleeve via screws; A traction block is welded to the outer wall of the bottom of the vertical reciprocating screw, and a lifting sleeve is slidably connected to the outer wall of the traction block, a lifting plate is welded to the outer wall of the top of the lifting sleeve, and a spring is fixedly connected between the lifting plate and the mounting frame, a connecting rod is welded to the bottom of the outer wall of one side of the lifting sleeve, and connecting columns are welded to the outer walls of both ends of the connecting rod, and a dust hopper with air holes is welded to the outer wall of the bottom of the connecting column.

[0008] Preferably, a sleeve is welded to the outer wall of the bottom of the mounting frame, and limiting grooves are provided around the outer wall of the sleeve. Limiting blocks are provided around the outer wall of the lifting plate, and the limiting blocks are slidably connected to the inner wall of the limiting groove.

[0009] Preferably, a guide rod is welded to one end of the outer wall of the top of the connecting rod away from the sleeve, and a fixing plate for mounting on the inner wall of the wall is slidably connected to the outer wall of the guide rod.

[0010] Preferably, a transverse plate is fixedly connected to the outer wall of one side of the first threaded sleeve, and a transverse groove is provided on the inner wall of the transverse plate; a guide block is provided on the outer wall of one side of the second threaded sleeve, and the guide block is slidably connected to the inner wall of the transverse groove.

[0011] Preferably, a vertical slot is provided on an outer wall of one side of the mounting frame, and a transverse reciprocating screw rod is provided through the inner wall of the vertical slot.

[0012] Preferably, the bottom outer wall of the vertical reciprocating screw is rotatably connected to the bottom inner wall of the mounting frame through a bearing, and the end of the horizontal reciprocating screw away from the first threaded sleeve is rotatably connected to the inner wall of one end of the horizontal plate through a bearing.

[0013] Preferably, an air inlet and an exhaust port are respectively provided on both sides of the outer wall of the bottom of the wall, and a dust hopper is located on the inner walls of the air inlet and the exhaust port, and the dust hopper is tightly attached to the outer wall of the bottom of the wall.

[0014] Preferably, a liquid crystal display screen is embedded in the inner wall of one side of the wall, and a cooling fan is located on one side of the liquid crystal display screen.

[0015] The beneficial effects of the present invention are: 1.

The gear and rack mesh and rotate, which in turn drives the horizontal reciprocating screw to rotate, allowing the second threaded sleeve to drive the cooling fan to move horizontally back and forth. This combined horizontal and vertical movement enables the cooling fan to fully cover the LCD screen, solving the problem of limited cooling range of traditional fans and improving the uniformity of heat dissipation. 2. The present invention's efficient heat dissipation LCD screen uses a vertical reciprocating screw to rotate the traction block, whose wedge-shaped structure propels the lifting sleeve up and down, and drives the dust hopper to move via a connecting rod and a connecting column. When heat dissipation is not required, a spring causes the dust hopper to close the air inlet and exhaust ports to block dust. When heat dissipation is required, the dust hopper moves downward, increasing the air circulation channel and accelerating heat dissipation. This solves the problem of the air inlet and exhaust port diameters being unable to be adjusted, and achieves synergy between heat dissipation and dust prevention. 3. The high-efficiency heat-dissipating LCD screen of the present invention uses a servo motor as a power source to simultaneously drive the compound motion of the cooling fan and the reciprocating lifting and lowering of the dust hopper, so that the two work together. When the cooling fan expands the heat dissipation range, the dust hopper synchronously adjusts the flow rate of the air inlet and exhaust port to accelerate air circulation. This linkage structure solves the problem of lack of coordination between the cooling fan and the air intake and exhaust systems, and significantly improves the overall heat dissipation performance.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figures 1-10 , Example 1, a high-efficiency heat dissipation type LCD screen, including a mounting frame 1 installed on the inner wall of a wall 29, the top outer wall of the mounting frame 1 is fixedly connected to a servo motor 2 by screws, and the output shaft of the servo motor 2 is fixedly connected to a vertical reciprocating screw 3 by a coupling, a first threaded sleeve 4 is screwed on the outer wall of the vertical reciprocating screw 3, and a gear 5 is rotatably connected to the outer wall of one side of the first threaded sleeve 4, a rack 6 is meshed on the outer wall of the gear 5, a horizontal reciprocating screw 7 is fixedly connected to the outer wall of the gear 5, and a second threaded sleeve 8 is screwed on the outer wall of the horizontal reciprocating screw 7, the top outer wall of the second threaded sleeve 8 is fixedly connected to a cooling fan 9 by screws, and the rack 6 is fixedly connected to the bottom inner wall of the mounting frame 1 by screws.

[0020] Through the above scheme, the servo motor 2 provides power for the movement of the entire cooling fan 9. When the servo motor 2 drives the vertical reciprocating screw 3 to rotate, the first threaded sleeve 4 will perform vertical reciprocating motion along the vertical reciprocating screw 3. Since the gear 5 is engaged with the rack 6, the first threaded sleeve 4 will drive the gear 5 to rotate when it moves, and then the horizontal reciprocating screw 7 is rotated, allowing the second threaded sleeve 8 to drive the cooling fan 9 to perform horizontal reciprocating motion. This combination of horizontal and vertical movement allows the cooling fan 9 to cover a larger area of ​​the LCD screen 27, solving the problem of limited heat dissipation range of traditional fans. The rack 6 is fixed on the mounting frame 1, providing a stable engagement basis for the rotation of the gear 5, thereby ensuring the stability of the movement.

[0021] In this embodiment, the servo motor 2 drives the vertical reciprocating screw 3 to rotate, so that the first threaded sleeve 4 drives the gear 5 to move back and forth vertically, and the gear 5 engages with the rack 6 to produce rotation, thereby driving the horizontal reciprocating screw 7 to rotate, and allowing the second threaded sleeve 8 to drive the cooling fan 9 to move back and forth horizontally. This combined horizontal and vertical movement enables the cooling fan 9 to fully cover the LCD screen 27, solving the problem of limited cooling range of traditional fans and improving the uniformity of cooling.

[0022] In the second embodiment, a traction block 10 is welded to the outer wall of the bottom of the vertical reciprocating screw 3, and a lifting sleeve 11 is slidably connected to the outer wall of the traction block 10, a lifting plate 12 is welded to the outer wall of the top of the lifting sleeve 11, and a spring 13 is fixedly connected between the lifting plate 12 and the mounting frame 1, a connecting rod 14 is welded to the bottom of the outer wall of one side of the lifting sleeve 11, and connecting columns 15 are welded to the outer walls of both ends of the connecting rod 14, and a dust hopper 16 with air holes is welded to the outer wall of the bottom of the connecting column 15.

[0023] Through the above scheme, when the vertical reciprocating screw 3 rotates, it will drive the traction block 10 to rotate synchronously. The wedge-shaped structure of the traction block 10 will periodically squeeze the lifting sleeve 11, causing the lifting sleeve 11 to move downward and stretch the spring 13 at the same time. When the raised part of the traction block 10 is turned away, the spring 13 resets and drives the lifting sleeve 11 to move upward. The reciprocating motion of the lifting sleeve 11 is transmitted to the dust hopper 16 through the connecting rod 14 and the connecting column 15, realizing the up and down movement of the dust hopper 16. In this way, when heat dissipation is required, the dust hopper 16 moves downward periodically away from the air inlet 25 and the exhaust port 26 to increase the air circulation. When heat dissipation is not required, after the servo motor 2 completes the rotation operation, the traction block 10 is embedded in the lifting sleeve 11, and the dust hopper 16 is reset under the action of the spring 13, close to the air inlet 25 and the exhaust port 26 to play a dust-proof role.

[0024] In this embodiment, the vertical reciprocating screw 3 drives the traction block 10 to rotate, and its wedge-shaped structure pushes the lifting sleeve 11 to lift and reciprocate, and drives the dust hopper 16 to move through the connecting rod 14 and the connecting column 15. When heat dissipation is not required, the spring 13 causes the dust hopper 16 to close the air inlet 25 and the exhaust port 26 to block dust. When heat dissipation is required, the dust hopper 16 moves downward to increase the air circulation channel and accelerate heat dissipation, thereby solving the problem that the diameter of the air inlet 25 and the exhaust port 26 cannot be adjusted, and realizing the coordination of heat dissipation and dust prevention.

[0025] A sleeve 17 is welded to the outer wall of the bottom of the mounting frame 1, and a limiting groove 18 is provided around the outer wall of the sleeve 17. A limiting block 28 is provided around the outer wall of the lifting plate 12, and the limiting block 28 is slidably connected to the inner wall of the limiting groove 18.

[0026] Through the above scheme, the sleeve 17 supports and guides the lifting plate 12, and the limit block 28 slides in the limit groove 18, which can limit the movement direction of the lifting plate 12 and prevent the lifting plate 12 from rotating or shifting during the lifting process, thereby ensuring the stability of the movement of the lifting sleeve 11 and the dust bucket 16 and avoiding the impact of shaking on the dustproof and heat dissipation effects.

[0027] A guide rod 19 is welded to one end of the top outer wall of the connecting rod 14 away from the sleeve 17 , and a fixing plate 20 for mounting on the inner wall of the wall 29 is slidably connected to the outer wall of the guide rod 19 .

[0028] Through the above-mentioned solution, the cooperation between the guide rod 19 and the fixed plate 20 provides additional support for the connecting rod 14. When the connecting rod 14 moves up and down with the lifting sleeve 11, the guide rod 19 slides in the fixed plate 20, which can prevent the connecting rod 14 from bending or deflecting due to uneven force, ensuring that the connecting rod 14 can stably drive the dust bucket 16 to move, further improving the stability of the structure.

[0029] A transverse plate 22 is fixedly connected to the outer wall of one side of the first threaded sleeve 4, and a transverse groove 21 is opened on the inner wall of the transverse plate 22. A guide block 23 is provided on the outer wall of one side of the second threaded sleeve 8, and the guide block 23 is slidably connected to the inner wall of the transverse groove 21.

[0030] Through the above scheme, the horizontal plate 22 provides support for the horizontal reciprocating screw 7, and the guide block 23 slides in the horizontal groove 21, which can limit the movement of the second threaded sleeve 8 and prevent the second threaded sleeve 8 from rotating with the horizontal reciprocating screw 7, ensuring that the second threaded sleeve 8 can only perform horizontal reciprocating motion along the horizontal reciprocating screw 7, ensuring the stability of the horizontal movement of the cooling fan 9, and making the heat dissipation more uniform.

[0031] A vertical slot 24 is formed on the outer wall of one side of the mounting frame 1 , and a transverse reciprocating screw rod 7 is provided through the inner wall of the vertical slot 24 .

[0032] Through the above-mentioned scheme, the vertical groove 24 provides space for the horizontal reciprocating screw rod 7 to move vertically. When the first threaded sleeve 4 drives the horizontal reciprocating screw rod 7 to move vertically, the vertical groove 24 can prevent the mounting frame 1 from obstructing the movement of the horizontal reciprocating screw rod 7, ensuring that the horizontal reciprocating screw rod 7 can move smoothly with the first threaded sleeve 4, thereby ensuring the continuity of the horizontal and vertical movement of the cooling fan 9.

[0033] The bottom outer wall of the vertical reciprocating screw rod 3 is rotatably connected to the bottom inner wall of the mounting frame 1 through a bearing, and the end of the horizontal reciprocating screw rod 7 away from the first threaded sleeve 4 is rotatably connected to the inner wall of one end of the horizontal plate 22 through a bearing.

[0034] Through the above-mentioned scheme, the bearing connection can reduce the friction of the vertical reciprocating screw 3 and the horizontal reciprocating screw 7 during rotation, making their rotation smoother, reducing mechanical wear, and extending the service life of the equipment. At the same time, the bearing provides stable support for the vertical reciprocating screw 3 and the horizontal reciprocating screw 7, ensuring that the vertical reciprocating screw 3 and the horizontal reciprocating screw 7 will not deviate during rotation, thereby ensuring the stability of the entire transmission structure.

[0035] An air inlet 25 and an air outlet 26 are respectively provided on both sides of the bottom outer wall of the wall 29 , and a dust hopper 16 is located on the inner walls of the air inlet 25 and the air outlet 26 , and the dust hopper 16 is closely attached to the bottom outer wall of the wall 29 .

[0036] Through the above-described solution, the air inlet 25 and the exhaust 26 serve as air circulation channels, providing an air source and outlet for heat dissipation. The dust hopper 16 is located within the air inlet 25 and the exhaust 26, close to the wall 29 when heat dissipation is not required. This prevents dust from entering through the air inlet 25 and the exhaust 26. When heat dissipation is required, the dust hopper 16 moves downward, increasing the flow area of ​​the air inlet 25 and the exhaust 26, accelerating air exchange and improving heat dissipation efficiency.

[0037] An LCD screen 27 is embedded in the inner wall of one side of the wall 29, and a cooling fan 9 is located on one side of the LCD screen 27. A heat dissipation strip is set on the outer wall of one side of the LCD screen 27, and a temperature sensor and a control module are installed inside the LCD screen 27. The control module is connected to the temperature sensor, the servo motor 2 and the cooling fan 9 through signal lines.

[0038] Through the above solution, the heat dissipation strips of LCD screen 27 can increase the heat dissipation area, and in conjunction with cooling fan 9, improve the heat dissipation effect. A temperature sensor monitors the temperature of LCD screen 27 in real time and transmits the data to the control module. The control module controls the start and stop of servo motor 2 and cooling fan 9 based on the temperature, achieving intelligent heat dissipation. When the temperature is too high, the device starts to dissipate heat, and when the temperature is normal, the device shuts down, saving energy.

[0039] Working Principle: When LCD screen 27 is operating, an internal temperature sensor monitors its temperature in real time and transmits the data to the control module. This control module uses the STM32F103C8T6 (ARM Cortex-M3 core), supports multiple PWM outputs, and can precisely control the start and stop of servo motor 2 and cooling fan 9. When the temperature exceeds a set threshold, the control module starts servo motor 2 and cooling fan 9. Servo motor 2 rotates the vertical reciprocating screw 3, causing the first threaded sleeve 4 to reciprocate vertically along the vertical reciprocating screw 3. Gear 5 rotates due to engagement with rack 6, driving the horizontal reciprocating screw 7 to rotate, allowing the second threaded sleeve 8 to drive the cooling fan 9 to reciprocate horizontally, dissipating heat over a large area of ​​LCD screen 27.

[0040] At the same time, the vertical reciprocating screw 3 drives the traction block 10 to rotate, and the wedge-shaped structure of the traction block 10 periodically squeezes the lifting sleeve 11, so that the lifting sleeve 11 drives the lifting plate 12 to stretch the spring 13 and move downward, and drives the dust hopper 16 to move downward through the connecting rod 14 and the connecting column 15, away from the air inlet 25 and the exhaust port 26, thereby increasing the air circulation. When the raised part of the traction block 10 rotates away, the spring 13 resets and drives the lifting sleeve 11 and the dust hopper 16 to move upward.

[0041] When the temperature sensor detects that the temperature of the LCD screen 27 drops to a safe range, the control module turns off the servo motor 2 and the cooling fan 9, and the dust hopper 16 is reset under the action of the spring 13, close to the air inlet 25 and the exhaust port 26, playing a dust-proof role.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
