Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and more specifically, to a rotatable liquid crystal display screen with a heat dissipation effect. Background Art

[0002] A liquid crystal display (LCD) is a display device that uses liquid crystal materials as the display medium. It controls the transmission and blocking of light through the arrangement change of liquid crystal molecules, thereby realizing the display of images.

[0003] In special environments such as ships, the use of display screens faces many challenges. First, the movement of the ship's hull is relatively complex and often in a shaking state, which makes the ordinary display screen fixing method difficult to meet the requirements, and the display screen is prone to loosen or even fall due to the inertial force generated by the shaking. Second, in the ship environment, the air humidity is relatively high and there is more dust. If the display screen does not have good protection measures, it is easy to get damp and accumulate dust, thus affecting its performance and service life. In addition, the display screen generates heat during long-term use. If the heat cannot be dissipated in a timely and effective manner, it will also have an adverse impact on the normal operation and life of the display screen. Summary of the Invention

[0004] The present invention provides a rotatable liquid crystal display screen with a heat dissipation effect, which solves the problems mentioned in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A rotatable liquid crystal display screen with a heat dissipation effect, including a display screen, further including:

[0006] A fixing mechanism, the fixing mechanism is arranged on the back of the display screen, and the fixing mechanism is used to fix the display screen;

[0007] A protection mechanism, the protection mechanism is fixedly arranged inside the fixing mechanism, and the protection mechanism is used to protect the fixing mechanism;

[0008] Wherein the fixing mechanism includes an outer housing, the outer housing is arranged on the back of the display screen, a fastening plate is fixedly connected to the surface of the outer housing away from the display screen, a mounting plate is fixedly connected to the outer surface of the middle part of the fastening plate, a rotating disk is rotatably connected to the outer surface of the mounting plate, a support rod is fixedly connected to the surface of the rotating disk away from the mounting plate, a covering plate is arranged on the side of the outer housing close to the display screen, the surface of the covering plate away from the outer housing is attached to the back of the display screen, and a clamping plate is fixedly connected to the outer end of the covering plate.

[0009] Preferably, a moving frame is arranged inside the outer shell body. Sliding sleeves are fixedly connected to the outer surfaces on both sides of the moving frame. A sliding rod is slidably sleeved inside the sliding sleeve, and both ends of the sliding rod are fixedly connected to the inner surfaces on the upper and lower sides of the outer shell body.

[0010] Preferably, the surface of the moving frame away from the fastening plate is fixedly connected to the surface of the inner end of the covering plate away from the display screen.

[0011] Preferably, deformation capsules are fixedly connected to the outer surfaces on the upper and lower sides of the moving frame. The deformation capsules are made of rubber material. The outer surface of the deformation capsule away from the moving frame is fixedly connected to the inner surfaces on the upper and lower sides of the outer shell body. The deformation capsules are arranged in a strip shape. First, the display screen is clamped inside the clamping plate to achieve the fixed installation of the display screen. Then, this liquid crystal screen is fixedly connected to the designated position of the ship through a support rod. By rotatably connecting the mounting plate and the rotating disc, the display angle of this liquid crystal screen can be adjusted, facilitating a better display effect.

[0012] Preferably, the protection mechanism includes a stabilizing plate. The stabilizing plate is fixedly connected to the inner surface of the deformation capsule away from the moving frame. A sliding groove is formed on the inner surface of the stabilizing plate. Three sliding grooves are formed in the same deformation capsule. Limiting rods are fixedly connected to both side surfaces of the sliding groove.

[0013] Preferably, the limiting rods are arranged in pairs. Moving plates are symmetrically slidably connected to the outer surfaces of the limiting rods. A first support plate is elastically rotatably connected to the upper surface of the moving plate. The first support plate is inclined. A movement groove is formed in the middle of the first support plate. A plugging rod is fixedly connected to the middle of the first support plate.

[0014] Preferably, a second support plate is rotatably connected to the plugging rod. The second support plate is arranged in the movement groove. The end of the second support plate is elastically rotatably connected to the upper surface of the moving plate. The first support plate and the second support plate are combined into an X shape.

[0015] Preferably, a matching plate is arranged on the side of the first support plate away from the moving plate. The matching plate is fixedly connected to the inner surface of the deformation capsule away from the stabilizing plate. The matching plate and the stabilizing plate are arranged in parallel. An air outlet hole is formed through the outer surface of the matching plate. The air outlet hole runs through the moving frame. A one-way valve is arranged in the air outlet hole. Air inlet holes are formed through the outer surfaces on the upper and lower sides of the fastening plate. The air inlet holes communicate with the internal cavity of the deformation capsule. A one-way valve is arranged in the air inlet hole. A sponge plate is arranged outside the air inlet hole. The sponge plate is fixedly attached to the outer surface of the fastening plate.

[0016] Preferably, the inside of the clamping plate is hollow. A pressurizing plate is fixedly embedded through one side of the clamping plate close to the display screen. The pressurizing plate is made of a rubber plate. Buffer bags are fixedly connected to the inner surfaces on both sides of the stabilizing plate. The outer surfaces of the buffer bags away from the stabilizing plate are fixedly connected to the inner surfaces on both sides of the mating plate. The inner cavities of the buffer bags communicate with the inner cavity of the clamping plate. When the deformation bag is squeezed as the moving frame moves, the mating plate on its inner surface will move towards the stabilizing plate, so that the mating plate gradually comes into contact with the first support plate and the second support plate and generates a squeezing force on the first support plate and the second support plate. When the first support plate and the second support plate are subjected to the squeezing force, they will rotate relative to each other, so that the included angle between the first support plate and the second support plate decreases, and then the moving plate fixedly connected to its end moves along the limiting rod to both sides in the sliding groove and resets when the squeezing force is removed.

[0017] The present invention provides a rotatable liquid crystal display screen with a heat dissipation effect, which has the following beneficial effects:

[0018] 1. When the rotatable liquid crystal display screen with a heat dissipation effect is used to display content to the crew, affected by the movement of the hull itself, the display screen will shake up and down. When the display screen shakes up and down, it will drive the clamping plate and the covering plate to shake up and down, so that the moving frame at the inner end of the covering plate slides up and down along the sliding rod through the sliding sleeve, thus greatly reducing the squeezing force on the clamping plate caused by the inertial force when the display screen shakes on the hull. As a result, the display screen is always in a good fixed state, avoiding the problem that the clamping force between the display screen and the clamping plate decreases due to long-term shaking, resulting in the display screen falling. Since a deformation bag is provided between the moving frame and the outer housing, when the moving frame shakes up and down, it will drive the moving frame to generate a squeezing force on the deformation bag. The reverse resistance provided by the deformation bag provides an elastic buffer force for the movement of the display screen, avoiding the short-distance and rapid movement of the display screen together with the clamping plate, reducing the clamping effect on the display screen, and further reducing the risk of the display screen falling.

[0019] 2. The rotatable liquid crystal display with heat dissipation effect can make the deformation bladder deform as a whole under the extrusion effect by setting the first support plate and the second support plate and cooperating with the matching plate, so as to protect the upper and lower surfaces of the deformation bladder, avoid damage to the deformation bladder caused by long-term irregular deformation, and at the same time, the first support plate and the second support plate can also provide a reverse extrusion force to the deformation bladder, thereby helping the deformation bladder to reset better. This not only facilitates the long-term use of the deformation bladder, but also forms a reverse elastic force to the extrusion of the moving frame, so that the display screen can infinitely tend to shake up and down with the same amplitude when shaking, avoiding the problem that the clamping effect between the display screen and the clamping plate is reduced due to long-term unequal shaking force. When the deformation bladder is forced to contract following the extrusion of the moving frame, the air pressure inside it is compressed and conveyed to the inside of the moving frame through the air outlet holes, thereby realizing the cooling effect on the display screen. When the deformation bladder resets, air pressure is replenished into it through the air inlet holes, so that the air on the back of the display screen is always in a flowing state due to the cooperation of the deformation bladders on the upper and lower sides, thereby greatly improving the cooling effect on the display screen.

[0020] 3. The rotatable liquid crystal display with heat dissipation effect can filter the air entering the inside of the deformation bladder by setting a sponge plate outside the air inlet hole, which can not only block dust from entering the deformation bladder, but also filter the moisture in the air, avoiding the problem that the display screen is damaged by moisture when humid air enters the inside of the moving frame. When the matching plate approaches the stabilizing plate, it will also squeeze the buffer bladder. The buffer bladder connects the matching plate and the stabilizing plate, thereby restricting the lateral misalignment amplitude between the matching plate and the stabilizing plate, avoiding the problem that the deformation bladder generates large lateral deformation and reduces the service life. At the same time, when the buffer bladder is squeezed, it will convey the air pressure inside it to the inside of the clamping plate, so that the pressure-increasing plate on the inner surface of the clamping plate expands outward and firmly adheres to the upper and lower sides of the display screen, that is, when the display screen shakes, the friction between the clamping plate and the display screen is increased, thereby automatically improving the fixing effect on the display screen.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The first embodiment: As Figures 1 to 8 shown, the present invention provides a technical solution: a rotatable liquid crystal display screen with a heat dissipation effect, including a display screen 1, and further including:

[0032] A fixing mechanism 2, the fixing mechanism 2 is arranged on the back of the display screen 1, and the fixing mechanism 2 is used to fix the display screen 1;

[0033] A protection mechanism 3, the protection mechanism 3 is fixedly arranged inside the fixing mechanism 2, and the protection mechanism 3 is used to protect the fixing mechanism 2;

[0034] Among them, the fixing mechanism 2 includes an outer shell 21, the outer shell 21 is arranged on the back of the display screen 1, a fastening plate 22 is fixedly connected to the surface of the outer shell 21 away from the display screen 1, a mounting plate 23 is fixedly connected to the outer surface of the middle part of the fastening plate 22, a rotating disc 24 is rotatably connected to the outer surface of the mounting plate 23, a support rod 25 is fixedly connected to the surface of the rotating disc 24 away from the mounting plate 23, a covering plate 26 is arranged on the side of the outer shell 21 close to the display screen 1, the surface of the covering plate 26 away from the outer shell 21 is attached to the back of the display screen 1, and a clamping plate 27 is fixedly connected to the outer end of the covering plate 26.

[0035] Inside the outer housing 21, a moving frame 28 is provided. On the outer surfaces of both sides of the moving frame 28, sliding sleeves 29 are fixedly connected. Inside the sliding sleeves 29, sliding rods 210 are slidably sleeved. The two ends of the sliding rods 210 are respectively fixedly connected to the inner surfaces of the upper and lower sides of the outer housing 21.

[0036] On the surface of the side of the moving frame 28 away from the fastening plate 22, it is fixedly connected to the surface of the inner end of the covering plate 26 away from the display screen 1.

[0037] On the outer surfaces of the upper and lower sides of the moving frame 28, deformation sacs 211 are fixedly connected. The deformation sacs 211 are made of rubber material. On the outer surface of the side of the deformation sacs 211 away from the moving frame 28, they are fixedly connected to the inner surfaces of the upper and lower sides of the outer housing 21. The deformation sacs 211 are arranged in a strip shape.

[0038] During operation, first, the display screen 1 is snap - connected inside the clamping plate 27 to achieve the fixed installation of the display screen 1. Then, this liquid crystal screen is fixedly connected to the designated position of the ship through the support rod 25. By rotatably connecting the mounting plate 23 and the rotating disk 24, the display angle of this liquid crystal screen can be adjusted to facilitate a better display effect. When showing content to the crew through this liquid crystal screen, affected by the movement of the hull itself, the display screen 1 will shake up and down. When the display screen 1 shakes up and down, it will drive the clamping plate 27 and the covering plate 26 to shake up and down, thereby causing the moving frame 28 at the inner end of the covering plate 26 to slide up and down along the sliding rod 210 through the sliding sleeve 29, thus greatly reducing the extrusion force caused by the inertial force on the clamping plate 27 when the display screen 1 shakes due to the hull's shaking, so that the display screen 1 is always in a good fixed state, avoiding the problem that the clamping force between the display screen 1 and the clamping plate 27 decreases due to long - term shaking, resulting in the dropping of the display screen 1. And a deformation sac 211 is provided between the moving frame 28 and the outer housing 21. Therefore, when the moving frame 28 shakes up and down, it will drive the moving frame 28 to exert an extrusion force on the deformation sac 211. The reverse resistance provided by the deformation sac 211 provides an elastic buffer force for the movement of the display screen 1, avoiding the short - distance and rapid movement of the display screen 1 together with the clamping plate 27, reducing the clamping effect on the display screen 1, and further reducing the risk of the display screen 1 dropping.

[0039] The second embodiment: As Figures 1 to 8 shown, the protection mechanism 3 includes a stabilizing plate 31. The stabilizing plate 31 is fixedly connected to the inner surface of the side of the deformation sac 211 away from the moving frame 28. On the inner surface of the stabilizing plate 31, sliding grooves 32 are opened. Three sliding grooves 32 are opened in the same deformation sac 211. On the two side surfaces of the sliding grooves 32, limiting rods 33 are fixedly connected.

[0040] The limiting rods 33 are arranged in pairs, and moving plates 34 are symmetrically and slidably connected to the outer surfaces of the limiting rods 33. The upper surfaces of the moving plates 34 are elastically and rotatably connected to first support plates 35. The first support plates 35 are inclined. Movement grooves 36 are formed in the middles of the first support plates 35, and inserting rods 37 are fixedly connected to the middles of the first support plates 35.

[0041] Inserting rods 37 are rotatably connected to second support plates 38. The second support plates 38 are arranged in the movement grooves 36. The ends of the second support plates 38 are elastically and rotatably connected to the upper surfaces of the moving plates 34. The first support plates 35 and the second support plates 38 are combined into an X shape.

[0042] A matching plate 39 is arranged on the side of the first support plate 35 away from the moving plate 34. The matching plate 39 is fixedly connected to the inner surface of the deformation bladder 211 away from the stabilizing plate 31. The matching plate 39 and the stabilizing plate 31 are arranged parallel to each other. Air outlet holes 310 are formed through the outer surface of the matching plate 39. The air outlet holes 310 penetrate through the moving frame 28. One-way valves are arranged in the air outlet holes 310. Air inlet holes 311 are formed through the upper and lower outer surfaces of the buckling plate 22. The air inlet holes 311 communicate with the internal cavity of the deformation bladder 211. One-way valves are arranged in the air inlet holes 311. A sponge plate 312 is arranged outside the air inlet holes 311. The sponge plate 312 is fixedly attached to the outer surface of the buckling plate 22.

[0043] The interior of the clamping plate 27 is hollow. A pressurizing plate 313 is fixedly embedded through the side of the clamping plate 27 close to the display screen 1. The pressurizing plate 313 is made of a rubber plate. Buffer bladders 314 are fixedly connected to the inner surfaces of both sides of the stabilizing plate 31. The outer surfaces of the buffer bladders 314 away from the stabilizing plate 31 are fixedly connected to the inner surfaces of both sides of the matching plate 39. The internal cavities of the buffer bladders 314 communicate with the internal cavity of the clamping plate 27.

[0044] During operation, when the deformation bladder 211 is squeezed as the moving frame 28 moves, the mating plate 39 on its inner surface will move towards the stabilizing plate 31, causing the mating plate 39 to gradually come into contact with the first support plate 35 and the second support plate 38, and exerting a squeezing force on the first support plate 35 and the second support plate 38. When the first support plate 35 and the second support plate 38 are subjected to the squeezing force, they will rotate relative to each other, reducing the angle between the first support plate 35 and the second support plate 38. This, in turn, causes the moving plate 34 fixedly connected to their ends to move along the limiting rod 33 in the sliding groove 32 towards both sides and reset when the squeezing force is removed. By providing the first support plate 35 and the second support plate 38 and their cooperation with the mating plate 39, the deformation bladder 211 can deform as a whole when deformed under extrusion, protecting the upper and lower surfaces of the deformation bladder 211 and preventing damage caused by long-term irregular deformation. At the same time, the first support plate 35 and the second support plate 38 can also provide a reverse squeezing force to the deformation bladder 211, helping the deformation bladder 211 to reset better. This not only facilitates the long-term use of the deformation bladder 211 but also forms a reverse elastic force against the extrusion of the moving frame 28, enabling the display screen 1 to tend to shake up and down with the same amplitude when shaken, avoiding the problem of reduced clamping effect between the display screen 1 and the clamping plate 27 due to long-term unequal shaking forces. When the deformation bladder 211 is forced to contract following the extrusion of the moving frame 28, the air pressure inside it is compressed and conveyed through the air outlet hole 310 to the inside of the moving frame 28, achieving a cooling effect on the display screen 1. When the deformation bladder 211 resets, air pressure is replenished through the air inlet hole 311, enabling the deformation bladders 211 on the upper and lower sides to cooperate to keep the air on the back of the display screen 1 in a flowing state, significantly enhancing the cooling effect on the display screen 1. By providing a sponge plate 312 outside the air inlet hole 311, the air entering the interior of the deformation bladder 211 can be filtered, blocking dust from entering the deformation bladder 211 and filtering moisture in the air to prevent damage to the display screen 1 caused by damp air entering the inside of the moving frame 28. When the mating plate 39 approaches the stabilizing plate 31, it will also squeeze the buffer bladder 314. The buffer bladder 314 connects the mating plate 39 and the stabilizing plate 31, restricting the lateral displacement amplitude between the mating plate 39 and the stabilizing plate 31 and preventing the problem of reduced service life due to large lateral deformation of the deformation bladder 211. At the same time, when the buffer bladder 314 is squeezed, the air pressure inside it is conveyed to the interior of the clamping plate 27, causing the pressure-increasing plate 313 on the inner surface of the clamping plate 27 to expand outward and firmly adhere to the upper and lower sides of the display screen 1. That is, when the display screen 1 shakes, the friction between the clamping plate 27 and the display screen 1 is increased, automatically enhancing the fixing effect on the display screen 1.
