Description

Technical Field

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

[0002] Liquid Crystal Display (LCD) is a display that uses liquid crystal material as a display medium. It controls the transmission and blocking of light by changing the arrangement 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 hull is complex and often in a shaking state, which makes it difficult for ordinary display screen fixing methods to meet the requirements. The display screen is prone to loosening or even falling due to the inertial force generated by the shaking. Secondly, in the ship environment, the air humidity is high and there is a lot of dust. If the display screen does not have good protection measures, it is easy to be damp and dusty, thus affecting its performance and service life. In addition, the display screen will generate heat during long-term use. If the heat cannot be dissipated in a timely and effective manner, it will also have an adverse effect on the normal operation and life of the display screen. Summary of the invention

[0007] Preferably, a surface of the movable frame on one side away from the snap-fit ​​plate is fixedly connected to a surface of the inner end of the covering plate on one side away from the display screen.

[0008] Preferably, deformation capsules are fixedly connected to the upper and lower outer surfaces of the movable frame, and the deformation capsules are made of rubber material. The outer surface of the deformation capsule on the side away from the movable frame is fixedly connected to the upper and lower inner surfaces of the outer shell, and the deformation capsule is arranged in a strip shape. The display screen is first clamped on the inner side of the clamping plate to achieve fixed installation of the display screen, and then the LCD screen is fixedly connected to the designated position of the ship through the support rod. The display angle of the LCD screen can be adjusted by rotating the connection between the mounting plate and the rotating disk, so as to achieve a better display effect.

[0009] Preferably, the protection mechanism includes a stabilizing plate, which is fixedly connected to the inner surface of the deformation bag away from the movable frame. The inner surface of the stabilizing plate is provided with a sliding groove. Three sliding grooves are provided in the same deformation bag, and limiting rods are fixedly connected to both side surfaces of the sliding groove.

[0010] Preferably, the limit rods are arranged in pairs as a group, the outer surfaces of the limit rods are symmetrically slidably connected to the movable plate, the upper surface of the movable plate is elastically rotatably connected to the first support plate, the first support plate is arranged at an angle, a motion groove is opened in the middle of the first support plate, and a plug-in rod is fixedly connected to the middle of the first support plate.

[0011] Preferably, a second support plate is rotatably connected to the plug-in rod, the second support plate is arranged in the moving groove, the end of the second support plate is elastically rotatably connected to the upper surface of the movable plate, and the first support plate and the second support plate are combined into an X shape.

[0012] Preferably, a matching plate is provided on the side of the first support plate away from the movable plate, and the matching plate is fixedly connected to the inner surface of the deformation bag away from the stabilizing plate. The matching plate and the stabilizing plate are arranged parallel to each other. An air outlet is penetrated through the outer surface of the matching plate, and the air outlet is arranged through the movable frame. A one-way valve is arranged in the air outlet. Air inlet holes are penetrated through the upper and lower outer surfaces of the snapping plate, and the air inlet hole is connected with the internal cavity of the deformation bag. A one-way valve is arranged in the air inlet hole. A sponge plate is arranged on the outside of the air inlet hole, and the sponge plate is fixedly attached to the outer surface of the snapping plate.

[0013] Preferably, the interior of the clamping plate is configured to be hollow, and a booster plate is fixedly embedded through the side of the clamping plate close to the display screen, and the booster plate is configured as a rubber plate. Buffer capsules are fixedly connected to the inner surfaces of both sides of the stabilizing plate, and the outer surface of the buffer capsule on the side away from the stabilizing plate is fixedly connected to the inner surfaces of both sides of the matching plate. The internal cavity of the buffer capsule is connected to the internal cavity of the clamping plate. When the deformation capsule is squeezed with the movement of the moving frame, the matching plate on its inner surface will move toward the stabilizing plate, so that the matching plate gradually comes into contact with the first support plate and the second support plate, and generates an extrusion 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 extrusion force, they will rotate relative to each other, thereby reducing the angle between the first support plate and the second support plate, thereby prompting the moving plate fixedly connected at its end to move to both sides in the sliding groove along the limit rod, and reset when it is free from the extrusion force.

[0014] The present invention provides a rotatable liquid crystal screen with heat dissipation effect. It has the following beneficial effects: 1. When the rotatable LCD screen with heat dissipation effect is used to display content to the crew, the display screen will shake up and down due to the movement of the hull itself. When the display screen shakes up and down, it will drive the clamping plate and the covering plate to shake up and down, thereby prompting the moving frame at the inner end of the covering plate to slide up and down along the sliding rod through the sliding sleeve, thereby greatly reducing the squeezing force of the display screen on the clamping plate caused by the inertial force when the hull shakes, so that the display screen is always in a good fixed effect, avoiding the problem of the display screen falling due to the reduction of the clamping force between the display screen and the clamping plate caused by long-term shaking. A deformation capsule is arranged between the moving frame and the outer shell, so when the moving frame shakes up and down, it will drive the moving frame to generate squeezing force on the deformation capsule, and the reverse resistance provided by the deformation capsule provides an elastic buffer force for the movement of the display screen, avoiding the display screen and the clamping plate from moving quickly over a short distance to reduce the clamping effect on the display screen, and further reducing the risk of the display screen falling.

[0015] 2. The rotatable LCD screen with heat dissipation effect can make the deformation capsule deform as a whole surface when deformed under the extrusion effect by arranging the first support plate and the second support plate and cooperating with the matching plate, thereby protecting the upper and lower surfaces of the deformation capsule and preventing the deformation capsule from being damaged under the long-term irregular deformation. At the same time, the first support plate and the second support plate can also provide a reverse extrusion force to the deformation capsule, thereby helping the deformation capsule to reset better, which is not only convenient for the long-term use of the deformation capsule, but also can form a reverse elastic force for the extrusion of the moving frame, thereby This allows the display screen to infinitely tend to the same amplitude of up and down shaking when shaking, avoiding the problem of long-term unequal shaking force causing the clamping effect between the display screen and the clamping plate to decrease. When the deformation bag is forced to shrink following the squeezing of the moving frame, the internal air pressure is compressed and transported to the inside of the moving frame through the air outlet, thereby achieving a cooling effect on the display screen. When the deformation bag is reset, the air pressure is replenished to the inside through the air inlet, so that the deformation bags on the upper and lower sides cooperate with each other to keep the air on the back of the display screen in a flowing state, thereby greatly improving the cooling effect on the display screen.

[0016] 3. The rotatable LCD screen with heat dissipation effect can filter the air entering the deformation bag by arranging a sponge plate on the outside of the air inlet, which can not only prevent dust from entering the deformation bag, but also filter the moisture in the air to prevent humid air from entering the inside of the movable frame and causing the display screen to be damaged by moisture. When the matching plate approaches the stabilizing plate, the buffer bag will be squeezed, and the matching plate and the stabilizing plate will be connected to each other through the buffer bag, thereby limiting the lateral misalignment between the matching plate and the stabilizing plate, avoiding the problem of large lateral deformation of the deformation bag and reducing the service life. At the same time, when the buffer bag is squeezed, its internal air pressure will be transmitted to the inside of the clamping plate, so that the booster plate on the inner surface of the clamping plate will expand outward and fit tightly on 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 of the display screen.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a rotatable liquid crystal screen with heat dissipation effect, including a display screen 1, and also including: A fixing mechanism 2, which is arranged on the back of the display screen 1 and is used to fix the display screen 1; The protection mechanism 3 is fixedly arranged inside the fixing mechanism 2, and is used to protect the fixing mechanism 2; The fixing mechanism 2 includes an outer shell 21, which is arranged on the back of the display screen 1. A buckling 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 middle outer surface of the buckling plate 22. A rotating disk 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 disk 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. A surface of the covering plate 26 away from the outer shell 21 is attached to the back of the display screen 1. A clamping plate 27 is fixedly connected to the outer end of the covering plate 26.

[0021] A moving frame 28 is provided inside the outer shell 21 , and sliding sleeves 29 are fixedly connected to the outer surfaces of both sides of the moving frame 28 . A sliding rod 210 is slidably sleeved on the inner surface of the sliding sleeve 29 . Both ends of the sliding rod 210 are fixedly connected to the upper and lower inner surfaces of the outer shell 21 .

[0022] The surface of the movable frame 28 on one side away from the buckling plate 22 is fixedly connected to the surface of the inner end of the covering plate 26 on the side away from the display screen 1 .

[0023] The upper and lower outer surfaces of the movable frame 28 are fixedly connected with deformation capsules 211, which are made of rubber material. The outer surface of the deformation capsule 211 away from the movable frame 28 is fixedly connected to the upper and lower inner surfaces of the outer shell 21, and the deformation capsule 211 is arranged in a strip shape.

[0024] During operation, the display screen 1 is first clamped on the inner side of the clamping plate 27 to achieve fixed installation of the display screen 1, and then the LCD screen is fixedly connected to the designated position of the ship through the support rod 25. The display angle of the LCD screen can be adjusted by rotating the connection between the mounting plate 23 and the rotating disk 24, so as to achieve a better display effect. When the content is displayed to the crew through the LCD screen, the display screen 1 will shake up and down due to the movement of the hull itself, and the shaking of the display screen 1 will drive the clamping plate 27 and the covering plate 26 to shake up and down, thereby prompting 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, thereby greatly reducing the display screen 1 when the hull shakes. During movement, the inertial force creates an extrusion pressure on the clamping plate 27, so that the display screen 1 is always in a good fixing effect, thereby avoiding the problem of long-term shaking causing the clamping force between the display screen 1 and the clamping plate 27 to be reduced and causing the display screen 1 to fall. A deformation capsule 211 is arranged between the moving frame 28 and the outer shell 21, so when the moving frame 28 shakes up and down, the moving frame 28 will drive the deformation capsule 211 to generate an extrusion pressure. The reverse resistance provided by the deformation capsule 211 provides an elastic buffering force for the movement of the display screen 1, thereby avoiding the display screen 1 and the clamping plate 27 from moving quickly over a short distance, reducing the clamping effect on the display screen 1, and further reducing the risk of the display screen 1 falling.

[0025] Second embodiment: Figures 1 to 8 As shown, the protection mechanism 3 includes a stabilizing plate 31, which is fixedly connected to the inner surface of the deformation bag 211 away from the moving frame 28. A sliding groove 32 is provided on the inner surface of the stabilizing plate 31. Three sliding grooves 32 are provided in the same deformation bag 211, and limiting rods 33 are fixedly connected to the two side surfaces of the sliding groove 32.

[0026] The limiting rods 33 are arranged in pairs in a group, and the outer surface of the limiting rods 33 is symmetrically slidably connected to the moving plate 34, and the upper surface of the moving plate 34 is elastically rotatably connected to the first support plate 35, the first support plate 35 is arranged at an angle, and a moving groove 36 is opened in the middle of the first support plate 35, and a plug-in rod 37 is fixedly connected to the middle of the first support plate 35.

[0027] The plug rod 37 is rotatably connected to a second support plate 38 , which is disposed in the motion slot 36 , and an end of the second support plate 38 is elastically rotatably connected to the upper surface of the movable plate 34 , and the first support plate 35 and the second support plate 38 are combined into an X shape.

[0028] A matching plate 39 is provided on the side of the first supporting plate 35 away from the movable plate 34. The matching plate 39 is fixedly connected to the inner surface of the deformation bag 211 away from the stabilizing plate 31. The matching plate 39 and the stabilizing plate 31 are arranged parallel to each other. An air outlet hole 310 is penetrated through the outer surface of the matching plate 39. The air outlet hole 310 is arranged through the movable frame 28. A one-way valve is arranged in the air outlet hole 310. Air inlet holes 311 are penetrated through the outer surfaces of the upper and lower sides of the buckling plate 22. The air inlet holes 311 are connected to the internal cavity of the deformation bag 211. A one-way valve is arranged in the air inlet hole 311. A sponge plate 312 is arranged on the outer side of the air inlet hole 311. The sponge plate 312 is fixedly attached to the outer surface of the buckling plate 22.

[0029] The interior of the clamping plate 27 is configured to be hollow, and a booster plate 313 is fixedly embedded through one side of the clamping plate 27 close to the display screen 1. The booster plate 313 is configured as a rubber plate. Buffer capsules 314 are fixedly connected to the inner surfaces of both sides of the stabilizing plate 31. The outer surface of the buffer capsule 314 on the side away from the stabilizing plate 31 is fixedly connected to the inner surfaces of both sides of the matching plate 39, and the internal cavity of the buffer capsule 314 is connected to the internal cavity of the clamping plate 27.

[0030] During operation, when the deformation capsule 211 is squeezed along with the movement of the moving frame 28, the matching plate 39 on its inner surface will move toward the side of the stabilizing plate 31, so that the matching plate 39 gradually comes into contact with the first support plate 35 and the second support plate 38, and generates an extrusion 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 extrusion force, they will rotate relative to each other, thereby reducing the angle between the first support plate 35 and the second support plate 38, thereby prompting the moving plate 34 fixedly connected at its end to move to both sides in the sliding groove 32 along the limiting rod 33, and reset when it is free from the extrusion force. The cooperation can make the deformation capsule 211 deform as a whole surface when it is deformed under the extrusion, so as to protect the upper and lower surfaces of the deformation capsule 211, and prevent the deformation capsule 211 from being damaged under the irregular deformation for a long time. At the same time, the first support plate 35 and the second support plate 38 can also provide a reverse extrusion force to the deformation capsule 211, so as to help the deformation capsule 211 to be better reset, which is not only convenient for the long-term use of the deformation capsule 211, but also can form a reverse elastic force for the extrusion of the moving frame 28, so that the display screen 1 can infinitely tend to the same amplitude of up and down shaking when shaking, and avoid the problem that the clamping effect between the display screen 1 and the clamping plate 27 is reduced due to the long-term unequal shaking force. When the deformation capsule 211 is forced to shrink due to the squeezing of the moving frame 28, the internal air pressure is compressed and transported to the inner side of the moving frame 28 through the air outlet 310, thereby achieving a cooling effect on the display screen 1. When the deformation capsule 211 is reset, the air pressure is supplemented to the inside through the air inlet 311, so that the deformation capsules 211 on the upper and lower sides cooperate with each other to make the air on the back of the display screen 1 always in a flowing state, thereby greatly improving the cooling effect on the display screen 1. By arranging a sponge plate 312 on the outer side of the air inlet 311, the air entering the deformation capsule 211 can be filtered, which can not only prevent dust from entering the deformation capsule 211, but also filter the moisture in the air to prevent humid air from entering the inner side of the moving frame 28 and causing The display screen 1 is damaged by moisture, and when the matching plate 39 approaches the stabilizing plate 31, the buffer capsule 314 is squeezed, and the matching plate 39 and the stabilizing plate 31 are connected to each other through the buffer capsule 314, thereby limiting the lateral misalignment between the matching plate 39 and the stabilizing plate 31, and avoiding the problem that the deformation capsule 211 produces a large lateral deformation and reduces the service life. At the same time, when the buffer capsule 314 is squeezed, its internal air pressure is also transmitted to the inside of the clamping plate 27, so that the booster plate 313 on the inner surface of the clamping plate 27 expands outward and fits firmly on 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, thereby automatically improving the fixing effect of the display screen 1.
