Description

Technical Field

[0001] The invention relates to the field of display screen equipment, and in particular to a self-cleaning windproof naked-eye 3D display screen. Background Art

[0002] The naked eye 3D display uses the parallax characteristics of the human eyes to obtain a realistic three-dimensional image display system with space and depth without any auxiliary equipment (such as 3D glasses, helmets, etc.). 3D is the abbreviation of three-dimensional, which means three-dimensional graphics. Displaying 3D graphics in a computer means displaying three-dimensional graphics in a plane. Unlike the real three-dimensional space in the real world, there is a real distance space. The computer only looks like the real world, so the 3D graphics displayed on the computer are just like the real world to the human eye. One of the characteristics of the human eye is that things that are close are larger and things that are far away are smaller, which will form a three-dimensional sense. Naked eye stereoscopic images are deeply favored by consumers for their real and vivid expression, beautiful and elegant environmental appeal, and strong and shocking visual impact.

[0003] Nowadays, many buildings at the intersections of commercial streets in cities are equipped with naked-eye 3D outdoor display screens. They are installed at the intersections to attract more viewers.

[0013] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0014] Firstly, when the dust adhered to the surface of the naked-eye 3D display screen of the present invention affects the use of the product, it is necessary to clean the surface of the naked-eye 3D display screen. At this time, the driving motor drives the driving shaft on the output end of the driving motor to rotate, and the rotation of the driving shaft drives the driving wheel to rotate. The rotation of the driving wheel drives the driven wheel to rotate on the fixed seat through the transmission of the driving belt, and the first matching wheel is located on the inner side of the driving belt to play a role of matching rotation. The first matching wheel is provided to limit the movement trajectory of the driving belt so that the movement trajectory of the driving belt is adapted to the shape of the naked-eye 3D display screen, thereby facilitating the operation of the subsequent cleaning device to avoid cleaning the naked-eye 3D display screen, and the second matching wheel is located on the outer side of the driving belt to play a role of matching rotation. The second matching wheel is also provided to limit the movement trajectory of the driving belt so that the movement trajectory of the driving belt The trace area is reduced, which is convenient for the installation of subsequent products and other operations. The driving belt rotates to drive the cleaning block to move, and the lower end of the cleaning block will be located in the sliding groove on the fixed seat to play a supporting and cooperative sliding role. The movement of the cleaning block will drive the cleaning box and the cleaning piece to move, so that the surface of the cleaning piece will fit the surface of the naked-eye 3D display screen and move in the shape of a smooth naked-eye 3D display screen. During the movement of the cleaning piece, the control valve is in an open state at this time, so that the water source inside the cleaning box flows into the cleaning piece, so that the cleaning piece is in a wet state, and then the control valve is closed, so that during the movement of the cleaning piece, the dust on the surface of the naked-eye 3D display screen will be wiped to clean it, thereby realizing the cleaning operation of the surface of the naked-eye 3D display screen. If the surface is exposed to the outside for a long time, there will be too much dust, which affects the normal use and viewing of the product.

[0015] Secondly, in the present invention, when the cleaning member moves from one side of the naked-eye 3D display screen to the other side of the naked-eye 3D display screen, the cleaning member will contact the cleaning plate, so that the cleaning member will be squeezed during the movement. After the cleaning member is squeezed, the water stains on the cleaning member will be squeezed into the cleaning box and discharged to the required position through the sewage discharge pipe on the cleaning box, thereby realizing the sewage removal operation of the cleaning member. At this time, the cleaning member is driven to return to the original path by the driving motor. In the process of the cleaning member returning to the original path, the moisture on the surface of the naked-eye 3D display screen that has just been cleaned can be wiped and absorbed by the cleaning member, thereby realizing the rapid wiping of the moisture on the surface of the naked-eye 3D display screen, improving the cleaning quality and cleaning efficiency. If the surface of the naked-eye 3D display screen is not completely cleaned by the cleaning member, the cleaning member can be repeatedly cleaned according to the actual situation.

[0016] Thirdly, in the present invention, when the cleaning member moves to clean the surface of the naked-eye 3D display screen, the driving shaft will synchronously rotate the transmission wheel, the rotation of the transmission wheel drives the rotating wheel to rotate through the transmission of the transmission belt, the rotation of the rotating wheel drives the transmission shaft to rotate, the rotation of the transmission shaft drives the protection roller to rotate, thereby releasing the protection member on the protection roller, and the movement of the cleaning box drives the two protection blocks to move, the movement of the two protection blocks drives the protection member fixed on the protection rod to move, so that the protection member moves in the shape of the naked-eye 3D display screen, and when the cleaning member wet-wipes the surface of the naked-eye 3D display screen, due to the air Dust in the air will be scattered everywhere, so when the dust encounters the wet surface of the naked-eye 3D display screen, it will make it easier for the dust to adhere to its surface, thus affecting the subsequent cleaning operation and not being conducive to the drying operation when the cleaning member returns. The protective member can be located just behind the cleaning member and move synchronously to cover the surface of the naked-eye 3D display screen, thereby preventing dust in the air from adhering to the surface of the naked-eye 3D display screen during the cleaning process, thereby improving the cleaning efficiency and cleaning quality of the naked-eye 3D display screen, and also reducing the number of cleaning times for the naked-eye 3D display screen, thereby increasing the service life of the naked-eye 3D display screen.

[0017] Fourthly, when encountering windy and rainy weather, the present invention first drives the upper pressing parts and the lower pressing parts on the output ends of the two hydraulic cylinders to move outward through the operation of the two pressing hydraulic cylinders, so that the cleaning device and the protective device have enough space during the movement and will not cause equipment collision. Then, the two pressing hydraulic cylinders stop running, and then the side ends of the cleaning plates of the cleaning parts are driven to move by the operation of the driving motor. At this time, the protective parts will also completely cover the surface of the naked-eye 3D display screen. At this time, the upper pressing parts and The lower pressing part returns to the original path, so that in the process of the upper pressing part and the lower pressing part returning to the original path, the upper ends of the unfolded protective part will be pressed onto the side ends of the fixing seat by the upper pressing part and the lower pressing part, thereby limiting the protective part and preventing it from failing to play a protective role due to excessive wind force. The surface of the naked-eye 3D display screen is covered by the protective part, so that the surface of the naked-eye 3D display screen will not be affected by the impact of rain and wind, thereby ensuring the safety of the naked-eye 3D display screen, thereby achieving the effect of protecting the naked-eye 3D display screen from rain and wind.

[0018] Fifthly, when the cleaning part of the present invention is located at the side end of the cleaning plate, the water filling port on the cleaning box is located directly below the drain pipe. When it rains, part of the rainwater will flow into the flow groove on the upper pressing part. Due to the inclined state of the flow groove, the rainwater will flow into the water filling port through the drain pipe and into the cleaning box, thereby realizing the collection of rainwater and utilizing the rainwater to clean the template of the naked-eye 3D display screen, thus avoiding waste of resources.

The device can clean the surface of the naked-eye 3D display screen 1, and can also play a role in preventing rain and wind, thereby ensuring the viewing effect of the naked-eye 3D display screen 1 and improving the service life of the product.

[0034] Working principle: When the dust adhered to the surface of the naked-eye 3D display screen 1 affects the use of the product, it is necessary to clean the surface of the naked-eye 3D display screen 1. At this time, the driving motor 22 is driven to drive the driving shaft 23 on the output end of the driving motor 22 to rotate, and the rotation of the driving shaft 23 drives the driving wheel 24 to rotate. The rotation of the driving wheel 24 drives the driven wheel 27 to rotate on the fixed seat 12 through the transmission of the driving belt 28, and the first matching wheel 25 is located on the inner side of the driving belt 28 to play a role of matching rotation. The first matching wheel 25 is provided to limit the movement trajectory of the driving belt 28, so that the movement trajectory of the driving belt 28 is adapted to the shape of the naked-eye 3D display screen 1, so as to facilitate the subsequent operation of the cleaning device 3 to avoid cleaning the naked-eye 3D display screen 1, and the second matching wheel 26 is located on the outer side of the driving belt 28 to play a role of matching rotation. The second matching wheel 26 is also provided to limit the movement trajectory of the driving belt 28, so that the driving belt 28 The movement track area is reduced, which is convenient for the installation of subsequent products and other operations. The driving belt 28 rotates to drive the cleaning block 31 to move, and the lower end of the cleaning block 31 will be located in the sliding groove 13 on the fixed seat 12 to play a supporting and sliding role. The movement of the cleaning block 31 will drive the cleaning box 32 and the cleaning member 33 to move, so that the surface of the cleaning member 33 will fit the surface of the naked-eye 3D display screen 1 and move in the shape of a smooth naked-eye 3D display screen 1. During the movement of the cleaning member 33, the control valve 11 is in an open state at this time, so that the water source inside the cleaning box 32 flows into the cleaning member 33, so that the cleaning member 33 is in a wet state, and then the control valve 11 is closed, so that during the movement of the cleaning member 33, the dust on the surface of the naked-eye 3D display screen 1 will be wiped to play a cleaning role, thereby realizing the cleaning operation of the surface of the naked-eye 3D display screen 1. The surface is exposed to the outside for a long time and there is too much dust, which affects the normal use and viewing of the product;

[0035] When the cleaning member 33 moves from one side of the naked-eye 3D display screen 1 to the other side of the naked-eye 3D display screen 1, the cleaning member 33 will contact the cleaning plate 37, so that the cleaning member 33 will be squeezed during the movement. After the cleaning member 33 is squeezed, the water stains of the cleaning member 33 will be squeezed into the cleaning box 35, and discharged to the required position through the sewage discharge pipe 36 on the cleaning box 35, thereby realizing the sewage removal operation of the cleaning member 33. At this time, the driving motor 22 drives the cleaning member 33 to return to the original path. During the process of the cleaning member 33 returning to the original path, the cleaning member 33 can wipe and absorb the moisture on the surface of the naked-eye 3D display screen 1 that has just been cleaned, thereby realizing the rapid wiping of the moisture on the surface of the naked-eye 3D display screen 1, improving the cleaning quality and cleaning efficiency. If the surface of the naked-eye 3D display screen 1 is not completely cleaned by the cleaning member 33, the cleaning member 33 can be repeatedly cleaned according to the actual situation.

[0036] When the cleaning member 33 moves to clean the surface of the naked-eye 3D display screen 1, the driving shaft 23 will synchronously rotate the transmission wheel 42, and the rotation of the transmission wheel 42 drives the rotating wheel 44 to rotate through the transmission of the transmission belt 43, and the rotation of the rotating wheel 44 drives the transmission shaft 45 to rotate, and the rotation of the transmission shaft 45 drives the protection roller 51 to rotate, so that the protection member 52 on the protection roller 51 is released, and the movement of the cleaning box 32 drives the two protection blocks 54 to move, and the movement of the two protection blocks 54 drives the protection member 52 fixed on the protection rod 55 to move, so that the protection member 52 will move in the shape of the naked-eye 3D display screen 1, and when the cleaning member 33 cleans the naked-eye 3D display screen 1 When the surface of the naked-eye 3D display screen 1 is wet wiped, since dust in the air will be scattered everywhere, dust will be more easily adsorbed on the wet surface of the naked-eye 3D display screen 1 when it encounters the wet surface, thereby affecting the subsequent cleaning operation and not being conducive to the wiping operation when the cleaning member 33 returns. The protective member 52 can be located just behind the cleaning member 33 to perform synchronous movement to cover the surface of the naked-eye 3D display screen 1, thereby preventing dust in the air from adhering to the surface of the naked-eye 3D display screen 1 during the cleaning process, thereby improving the cleaning efficiency and cleaning quality of the naked-eye 3D display screen 1, and also reducing the number of cleaning times for the naked-eye 3D display screen 1, thereby increasing the service life of the naked-eye 3D display screen 1;
