Description

Technical Field

[0001] The utility model relates to the technical field of naked-eye 3D, in particular to a naked-eye 3D display sky screen. Background Art

[0002] The naked eye 3D display uses the parallax characteristics of 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.). The naked eye three-dimensional image is characterized by its real and vivid expression, beautiful and high-pressure environmental appeal, and strong and shocking visual impact.

[0003] At present, the common types of naked-eye 3D technology are shutter type and polarized type.

[0004] The shutter type means that the image is divided into two frames, forming two sets of pictures corresponding to the left eye and the right eye, which are displayed continuously and alternately. At the same time, the infrared signal transmitter will synchronously control the switches of the left and right lenses of the shutter-type 3D glasses, so that the left and right eyes can see the corresponding pictures at a certain moment.

[0005] The polarized type uses the principle that light has a "vibration direction" to decompose the original image. The image is first divided into two groups of pictures: vertically polarized light and horizontally polarized light. Then the left and right sides of the 3D glasses use polarized lenses with different polarization directions respectively. In this way, the left and right eyes of a person can receive two groups of pictures, which are then synthesized into a three-dimensional image through the brain.

[0006] After searching, the patent with application number CN202122933426.0 discloses a new 3D display screen, including: a substrate, a display layer and an antistatic layer, the substrate is provided with a display layer, and an explosion-proof protective layer is provided between the display layer and the antistatic layer. The utility model can improve the heat dissipation effect of the display screen by setting a heat-absorbing layer, a heat-conducting column, a heat dissipation layer and a heat dissipation hole; can improve the protection effect of the display screen by setting an explosion-proof protective layer; can reduce the electrostatic adsorption of the display screen by an antistatic layer, a sealing layer and an anti-blue light layer, avoid water ingress into the body when cleaning the display screen and reduce damage to human eyes.

[0007] Some current large-scale naked-eye 3D display skylights are installed in crowded city squares, and the 3D skylights are in an exposed environment for a long time. Pollutants such as external dust will be adsorbed on the surface of the skylight. If they are not cleaned in time, the dust will enter the interior of the skylight from the gaps, affecting the stable operation of the skylight. If manual regular cleaning is used, workers need to be lifted to a high place and cleaned manually, which is not only time-consuming and labor-intensive, but also increases maintenance costs and poses safety hazards. Therefore, we need to propose a naked-eye 3D display skylight. Utility Model Content

DETAILED DESCRIPTION

[0025] 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.

[0026] Please refer to Figure 1-6 , the present invention provides a technical solution: a naked-eye 3D display sky screen, including a sky screen main body 1. A first groove 2 and a second groove 3 that are communicated are respectively opened on the sky screen main body 1. Specifically, there are four first grooves 2 and two second grooves 3. Two of the first grooves 2 are communicated with one of the second grooves 3, and the other two first grooves 2 are communicated with the other second groove 3. A cleaning mechanism 6 is installed in the first groove 2 in a retractable manner. A sliding seat 5 is slidably installed in the second groove 3, and the cleaning mechanism 6 is installed on the sliding seat 5, so that the cleaning mechanism 6 can be driven to move by the sliding seat 5;

[0027] The cleaning mechanism 6 includes a U-shaped plate 61. Two sets of cleaning rollers 67 with opposite rotation directions are rotatably installed inside the U-shaped plate 61. A dust extraction assembly located between the two sets of cleaning rollers 67 is also installed on the inner side wall of the U-shaped plate 61. The dust extraction assembly includes a box body 64 with an air pump inside. One side of the box body 64 is connected with a plurality of air extraction nozzles 65 arranged at equal intervals. An exhaust passage 611 is opened at the bottom side of the U-shaped plate 61. A guide pipe 66 is communicated between the box body 64 and the exhaust passage 611.

[0028] When the air pump operates, the floating dust swept up is sucked into the inside of the box body 64 through the air extraction nozzles 65, enters the exhaust passage 611 through the guide pipe 66, and then is discharged from below the cleaning mechanism 6.

[0029] A screw rod 4 is rotatably installed inside the second groove 3. The sliding seat 5 is threadedly connected to the screw rod 4. A forward and reverse motor for driving the screw rod 4 to rotate is installed on the side of the sky screen main body 1. The forward and reverse motor drives the screw rod 4 to rotate, and then drives the sliding seat 5 to move.

[0030] Installation plates 62 are installed on both the inner top and inner bottom of the U-shaped plate 61. The cleaning rollers 67 are rotatably installed between the two sets of installation plates 62. A sliding groove 51 is opened on one side of the sliding seat 5. The ends of the U-shaped plate 61 and the installation plates 62 are slidably installed inside the sliding groove 51, which plays a role in limiting the lifting of the cleaning mechanism 6.

[0031] A cylinder 63 is installed inside the first groove 2. One end of the piston rod of the cylinder 63 is connected with a limit block 631. A limit groove 621 is opened on one side of the installation plate 62. The limit block 631 and the limit groove 621 are correspondingly arranged.

[0032] The limiting block 631 is initially installed in the limiting groove 621. The U-shaped plate 61 can be pushed to move by the air cylinder 63. During cleaning, the cleaning mechanism 6 moves, the limiting block 631 disengages from the limiting groove 621. After cleaning is completed, the cleaning mechanism 6 resets, and the limiting block 631 enters the limiting groove 621 again. The piston rod of the air cylinder 63 contracts, pulling the cleaning mechanism 6 back into the first groove 2.

[0033] A driving component for driving the cleaning roller 67 to rotate is installed on the U-shaped plate 61. The driving component includes a motor 68 installed through a frame. A rotating shaft is rotatably installed at the inner top of the U-shaped plate 61. The outer walls of the output shaft of the motor 68 and the rotating shaft are both sleeved with a first gear 69.

[0034] Second gears 610 are sleeved on the outer walls of one ends of the two groups of cleaning rollers 67. The two groups of first gears 69 are respectively meshed with the two groups of second gears 610.

[0035] The motor 68 drives the two groups of cleaning rollers 67 to rotate through the first gear 69 and the second gear 610, and the rotation directions of the two groups of cleaning rollers 67 are opposite (so as to clean the floating dust towards the direction close to the U-shaped plate 61).

[0036] After the main body 1 of the awning of this device is used for a period of time, its surface will adsorb more floating dust due to static electricity. To prevent the floating dust from entering the interior of the awning through the awning connection gap, it is necessary to clean the floating dust on the surface of the awning through the cleaning mechanism 6. First, drive the air cylinder 63 (under the cooperation of the limiting groove 621 and the limiting block 631) to push the cleaning mechanism 6 out of the first groove 2, and make the U-shaped plate 61 be limited inside the sliding groove 51 through a spring plunger (not shown in the figure, and other limiting structures can also be used. The specific structure composition is prior art and is a technical means that those skilled in the relevant field can easily think of, so it will not be elaborated here);

[0037] Then drive the screw rod 4 to rotate through the forward and reverse rotation of the motor, drive the sliding seat 5 to move inside the second groove 3, and then drive the cleaning mechanism 6 to move (in this process, the limiting block 631 disengages from the limiting groove 621). At the same time, run the motor 68. The motor 68 drives the two groups of cleaning rollers 67 to rotate through the first gear 69 and the second gear 610, and the rotation directions of the two groups of cleaning rollers 67 are opposite (so as to clean the floating dust towards the direction close to the U-shaped plate 61). The air pump in the box body 64 runs, sucks the swept floating dust into the interior of the box body 64 through the air extraction nozzle 65, and enters the exhaust passage 611 through the air guide pipe 66, and then discharges from below the cleaning mechanism 6;

[0038] After cleaning is completed, drive the cleaning mechanism 6 back to the position of the first groove 2 through the forward and reverse rotation of the motor and the screw rod 4, and the limiting block 631 is inserted into the limiting groove 621. The piston rod of the air cylinder 63 retracts, driving the cleaning mechanism 6 to be received into the interior of the first groove 2.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
