Description

Technical Field

[0001] This invention relates to the field of liquid crystal display technology, specifically to a liquid crystal display with a screen protection structure. Background Technology

[0002] As a core component for information display and human-computer interaction, LCD screens are widely used in various scenarios such as home electronics, industrial control, outdoor terminals, medical equipment, automotive displays, and public facilities. With advantages such as clear display, low power consumption, thin and light size, and good visibility, they have become an indispensable part of modern electronic devices. Their display effect and service life directly affect the user experience, operational stability, and operating costs of the equipment.

[0003] Existing LCD screens, when used outdoors, are often directly exposed to the elements, making them susceptible to impacts from external objects. Without appropriate protective structures, the screens are easily scratched, cracked, or damaged, thus affecting the device's normal display function and lifespan. Therefore, this paper proposes an LCD screen with a screen protection structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a liquid crystal display screen with a screen protection structure, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liquid crystal display screen with a screen protection structure, comprising: a liquid crystal screen, wherein a bracket is hinged to the rear side wall of the liquid crystal screen; A base, which is fixed to the bottom of the bracket; A large fixing plate is fixed to the side wall of the LCD screen; A short rod, which passes through a large fixed plate and is slidably connected at the point of penetration; A baffle, which is fixed to the end of the short rod away from the large fixed plate; A large spring, one end of which is fixed to the side of the baffle near the large fixed plate, and the other end of which is fixedly connected to the large fixed plate; A mounting bracket, which is fixed above the LCD screen; A rotating rod, which passes through a fixed base and is rotatably connected at the point of penetration; A protective plate is fixed to the outer wall of the rotating rod; A torsion spring, one end of which is fixed to the side wall of the mounting base, and the other end of which is fixedly connected to the protective plate; A limiting groove is formed on the outer wall of the end of the rotating rod; A limiting rod is fixed to the end of the short rod near the large fixed plate. The upper end of the limiting rod is slidably connected to the limiting groove. The limiting rod is used to limit the rotation rod. When the front side of the LCD screen is hit, the baffle moves towards the large fixed plate. With the compression of the large spring, the baffle drives the short rod and the limiting rod to move away from the rotation rod. When the limiting rod disengages from the limiting groove, the rotation rod loses its limit. Under the reset action of the torsion spring, the rotation rod and the protective plate flip towards the front side of the LCD screen.

[0006] According to the above technical solution, a gear is fixed to the end of the rotating rod, and a small fixing plate is fixed to the side wall of the LCD screen near the gear. The small fixing plate has a sliding rod passing through it and is slidably connected at the point of penetration.

[0007] According to the above technical solution, a rack is fixed to the end of the sliding rod, the rack meshes with a gear, and the gear is used to drive the rack to move upward.

[0008] According to the above technical solution, the side wall of the LCD screen is provided with an insect-repelling mechanism, which is used to repel mosquitoes when used at night; a heat dissipation mechanism is provided below the LCD screen, which is used to dissipate heat from the screen.

[0009] According to the above technical solution, the insect-proof mechanism includes: a motor, which is fixed to the side wall of the LCD screen near the limiting groove; A cam, which is fixed to the output end of the motor; A square plate is fixed to the side of the LCD screen near the limiting groove.

[0010] According to the above technical solution, the square plate has a thin rod running through it and is slidably connected at the point of penetration. A collision plate is fixed to one end of the thin rod near the cam. A small spring is fixed to one side of the square plate near the collision plate. The small spring is fixedly connected to the collision plate. The cam is used to collide with the collision plate.

[0011] According to the above technical solution, the heat dissipation mechanism includes: a long box, which is fixed below the LCD screen; An air outlet is located on the upper wall of the elongated box; The short board is fixed to the upper wall of the long box.

[0012] According to the above technical solution, the short plate is slidably connected through a sliding rod, and a cover plate is fixed to the end of the sliding rod away from the short plate. A tension spring is fixed to the side of the short plate near the cover plate, and the tension spring is fixedly connected to the cover plate. A metal spring is fixed to the side of the short plate near the cover plate, and the metal spring is fixedly connected to the cover plate. The tension spring is used to bend the metal spring.

[0013] This invention provides a liquid crystal display screen with a screen protection structure. It has the following beneficial effects: 1. This invention comprises an LCD screen, a base, a bracket, a large fixed plate, a large spring, a short rod, a baffle, a limiting rod, a rotating rod, a fixed seat, a torsion spring, a protective plate, and a limiting groove. When the front of the LCD screen is impacted, the baffle moves towards the large fixed plate. With the compression of the large spring, the baffle drives the short rod and the limiting rod to move away from the rotating rod. When the limiting rod disengages from the limiting groove, the rotating rod loses its limiting position. Under the reset action of the torsion spring, the rotating rod and the protective plate flip towards the front of the LCD screen, shielding it and preventing further impacts. Furthermore, by incorporating a small fixed plate, a gear, a sliding rod, and a rack, as the protective plate and the rotating rod flip downwards to a position parallel to the LCD screen, the rotating rod drives the gear to rotate. The gear further drives the rack and sliding rod upwards. The meshing transmission of the gear and rack creates resistance to the rotation of the rotating rod, slowing its rotation speed and preventing damage to the LCD screen from the torsion spring's reset force.

[0014] 2. This invention, by incorporating a motor, cam, collision plate, square plate, small spring, and thin rod, addresses the issue that when the display screen is used outdoors, the light emitted at night attracts a large number of mosquitoes. The constant collisions of these insects with the LCD screen can damage it. When the motor is activated, it drives the cam to rotate. The cam's convex end then collides with the collision plate, causing the collision plate to move the thin rod closer to the square plate. The compression of the small spring and the vibration generated by the cam contacting the collision plate are transmitted throughout the display screen, repelling the mosquitoes and preventing them from remaining on the LCD screen.

[0015] 3. This invention, by incorporating a long box, an air outlet, a cover plate, a metal spring, a short plate, a slide bar, and a tension spring, addresses the issue that when the display screen is used outdoors, the LCD screen experiences high temperatures due to direct sunlight, which can easily cause aging and damage. Because the long box is positioned below the LCD screen, the temperature of the LCD screen rises, as does the temperature of the air inside the long box. When the temperature is very high, the metal spring softens, and under the resetting action of the tension spring, it is pulled upwards and bends. The cover plate and slide bar are then pulled closer to the short plate, preventing the cover plate from blocking the air outlet. The high-temperature gas inside the long box, through natural convection, flows upwards through the air outlet, continuously blowing onto the LCD screen, carrying away its heat and providing a cooling effect, thus mitigating the aging problem caused by high temperatures. Normally, the cover plate blocks the air outlet to prevent it from being obstructed by foreign objects. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0019] Please see Figures 1-7One embodiment of the present invention is as follows: a liquid crystal display screen with a screen protection structure, comprising: a liquid crystal screen 1, a base 2, a large fixing plate 4, a short rod 6, a baffle 7, a large spring 5, a fixing seat 10, a rotating rod 9, a protective plate 12, a torsion spring 11, a limiting groove 13, and a limiting rod 8; a bracket 3 is hinged to the rear side wall of the liquid crystal screen 1; the base 2 is fixed below the bracket 3; the large fixing plate 4 is fixed to the side wall of the liquid crystal screen 1; the short rod 6 passes through the large fixing plate 4 and is slidably connected at the point of penetration; the baffle 7 is fixed to the end of the short rod 6 away from the large fixing plate 4; one end of the large spring 5 is fixed to the side of the baffle 7 close to the large fixing plate 4; the other end of the large spring 5 is fixedly connected to the large fixing plate 4; the fixing seat 10 is fixed above the liquid crystal screen 1; and the rotating rod 9 passes through the fixing plate 12. The fixed seat 10 is rotatably connected through the through-hole. The protective plate 12 is fixed to the outer wall of the rotating rod 9. One end of the torsion spring 11 is fixed to the side wall of the fixed seat 10, and the other end of the torsion spring 11 is fixedly connected to the protective plate 12. The limiting groove 13 is opened on the outer wall of the end of the rotating rod 9. The limiting rod 8 is fixed to the end of the short rod 6 near the large fixed plate 4. The upper end of the limiting rod 8 is slidably connected to the limiting groove 13. The limiting rod 8 is used to limit the rotating rod 9. The end of the rotating rod 9 is fixed with a gear 15. The side wall of the LCD screen 1 near the gear 15 is fixed with a small fixed plate 14. The small fixed plate 14 has a sliding rod 16 through it and is slidably connected through the through-hole. The end of the sliding rod 16 is fixed with a rack 17. The rack 17 meshes with the gear 15. The gear 15 is used to drive the rack 17 to move upward.

[0020] By setting up LCD screen 1, base 2, bracket 3, large fixing plate 4, large spring 5, short rod 6, baffle 7, limit rod 8, rotating rod 9, fixing seat 10, torsion spring 11, protection plate 12 and limit groove 13, the problem of LCD screen 1 being easily damaged by collision is effectively solved, especially the secondary damage after collision is avoided, and the service life of LCD screen 1 is extended.

[0021] A small fixing plate 14, a gear 15, a sliding rod 16, and a rack 17 are provided to decelerate and buffer the protective plate 12 during its flipping process. This prevents the protective plate 12 from flipping too quickly under the restoring force of the torsion spring 11 and impacting the surface of the LCD screen 1, thus preventing secondary damage to the LCD screen 1.

[0022] In this embodiment, when the front side of the LCD screen 1 is subjected to an external collision, the collision force acts directly on the baffle 7, forcing the baffle 7 to move closer to the large fixed plate 4. During this process, the large spring 5 connected to the baffle 7 is compressed and deformed, storing elastic potential energy. Utilizing the elastic buffering effect of the large spring 5, a portion of the collision impact force can be initially offset, reducing the direct impact of the collision on the LCD screen 1. As the baffle 7 moves towards the large fixed plate 4, it simultaneously drives the short rod 6 fixedly connected to it to move as well. The short rod 6 then drives the limiting rod 8 to move away from the rotating rod 9. The limiting rod 8 was originally inserted into the limiting groove 13 opened on the rotating rod 9, providing a stable limiting constraint on the rotating rod 9 and preventing the rotating rod 9 from rotating arbitrarily. As the limiting rod 8 continues to move away from the rotating rod 9, when the limiting rod 8 completely disengages from the limiting groove 13, the limiting constraint effect on the rotating rod 9 completely disappears. At this time, the torsion spring 11, which was originally under torsional stress, will immediately release its elastic potential energy. Under the elastic restoring force of the torsion spring 11, the rotating rod 9 will rotate around the fixed base 10. While the rotating rod 9 is rotating, it will simultaneously drive the protective plate 12, which is fixedly connected to it, to flip towards the front of the LCD screen 1 until the protective plate 12 completely covers the front surface of the LCD screen 1, forming a comprehensive shielding and protection for the LCD screen 1.

[0023] As the protective plate 12 and the rotating rod 9 flip towards the front of the LCD screen 1 under the action of the torsion spring 11 until they are parallel to the LCD screen 1, the rotating rod 9 synchronously drives the gear 15 to rotate. Since the gear 15 meshes with the rack 17, the rotational motion of the gear 15 is converted into the linear motion of the rack 17, which in turn drives the sliding rod 16 to move upward. Under the meshing transmission action of the gear 15 and the rack 17, a certain resistance is generated to the rotation of the rotating rod 9, effectively slowing down the rotation speed of the rotating rod 9, so that the protective plate 12 can slowly and smoothly flip onto the surface of the LCD screen 1.

[0024] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the side wall of the LCD screen 1 is provided with an insect-repelling mechanism, which is used to repel mosquitoes when used at night; the insect-repelling mechanism includes: a motor 181, a cam 182, a square plate 184, a thin rod 186, a collision plate 183, and a small spring 185; the motor 181 is fixed on the side wall of the LCD screen 1 near the limiting groove 13, the cam 182 is fixed on the output end of the motor 181, and the square plate 184 is fixed on the side of the LCD screen 1 near the limiting groove 13.

[0025] A thin rod 186 passes through a square plate 184 and is slidably connected at the point of penetration. A collision plate 183 is fixed to one end of the thin rod 186 near the cam 182. A small spring 185 is fixed to one side of the square plate 184 near the collision plate 183. The small spring 185 is fixedly connected to the collision plate 183. The cam 182 is used to collide with the collision plate 183.

[0026] When the LCD screen 1 is used outdoors, it continuously emits light at night, which attracts a large number of mosquitoes. These mosquitoes constantly bump into the surface of the LCD screen 1, which over time scratches the surface of the LCD screen 1, affects the display effect, and may even damage the display components of the LCD screen 1, shortening its service life. This invention effectively solves the problem of damage caused by the gathering and collision of mosquitoes when the LCD screen 1 is used outdoors by setting up a motor 181, a cam 182, a collision plate 183, a square plate 184, a small spring 185, and a thin rod 186, thus ensuring the normal use of the LCD screen 1 in outdoor environments.

[0027] A heat dissipation mechanism is provided below the LCD screen 1. The heat dissipation mechanism is used to dissipate heat from the screen. The heat dissipation mechanism includes: a long box 191, an air outlet 192, a short plate 195, a slider 196, a cover plate 193, a tension spring 197, and a metal spring 194. The long box 191 is fixed below the LCD screen 1. The air outlet 192 is opened on the upper wall of the long box 191. The short plate 195 is fixed on the upper wall of the long box 191. The slider 196 passes through the short plate 195 and is slidably connected at the point of penetration. The cover plate 193 is fixed at the end of the slider 196 away from the short plate 195. The tension spring 197 is fixed on the side of the short plate 195 near the cover plate 193 and is fixedly connected to the cover plate 193. The metal spring 194 is fixed on the side of the short plate 195 near the cover plate 193 and is fixedly connected to the cover plate 193. The tension spring 197 is used to bend the metal spring 194.

[0028] By incorporating a long box 191, an air vent 192, a cover plate 193, a metal spring 194, a short plate 195, a slide bar 196, and a tension spring 197, the problem of excessively high temperatures and easy aging and damage caused by direct sunlight when the LCD screen 1 is used outdoors is effectively solved, thus extending the service life of the LCD screen 1.

[0029] In this embodiment, during operation: The motor 181 is started, and after it starts running, it drives the output shaft to rotate synchronously, which in turn drives the cam 182 to perform circular motion. The outer surface of the cam 182 has an irregular arc-shaped structure, and its convex end periodically contacts and collides with the collision plate 183. When the convex end of the cam 182 collides with the collision plate 183, it generates a lateral thrust on the collision plate 183, forcing the collision plate 183 to move closer to the square plate 184. During this process, the thin rod 186 connected to the collision plate 183 moves synchronously, and the small spring 185 is compressed and deformed, storing elastic potential energy. The vibration force generated by the contact and collision between the cam 182 and the collision plate 183 is transmitted to the entire display screen device through the thin rod 186, the square plate 184, the bracket 3, and other components, causing the display screen to produce slight high-frequency vibrations. This high-frequency vibration can effectively drive away mosquitoes that gather around the LCD screen 1, preventing them from staying stably on the surface of the LCD screen 1 and avoiding damage caused by continuous collisions with the LCD screen 1, thus ensuring the normal display and use of the LCD screen 1 in outdoor environments.

[0030] When the LCD screen 1 is used outdoors and exposed to direct sunlight, its temperature rises rapidly. This heat is continuously transferred to the lower elongated box 191, causing the air temperature inside the box to rise simultaneously. As the temperature inside the box rises, the metal spring 194 softens due to the high temperature, losing its original rigid support. At this point, the tension spring 197, which was previously stretched, releases its elastic potential energy. Under its elastic restoring force, it pulls the metal spring 194 upwards, causing it to bend and deform. This bending of the metal spring 194 simultaneously moves the slide rod 196 towards the short plate 195, which in turn moves the cover plate 193. Once the cover plate 193 reaches its preset position, it no longer obstructs the air vent 192 on the elongated box 191, allowing the air vent 192 to be fully open. The high-temperature gas inside the box 191, under natural convection, continuously blows upwards through the air vent 192 onto the surface of the LCD screen 1, creating a continuous airflow. These airflows can quickly remove the high heat from the surface of the LCD screen 1, thereby cooling the LCD screen 1 and effectively alleviating the aging problem caused by the high temperature environment. This also prevents the LCD screen 1 from experiencing display abnormalities or component damage due to prolonged high temperatures.
