[0030] With the continuous development and progress of projection technology, projection can be applied to more scenarios, such as setting up projection in cars, setting up projection in open places, etc., thus enriching entertainment life. A screen is a structure that can achieve projection.
[0031] The curtain structure in the related art has a technical problem that it is easy to curl up, thus affecting normal use.
[0032] Please refer to Figure 1This embodiment provides a projection device, which includes a projector (not shown) and a screen structure 100. The projector and the screen structure 100 are arranged at an interval, and the lens of the projector is arranged toward the screen structure 100. After the projector is started, its lens can project an image or video onto the screen structure 100, thereby realizing the projection work. The projection device can effectively improve the above-mentioned technical problems, can avoid the curling phenomenon of the screen when in use, ensure the normal use of the screen, and thus ensure the normal use of the projection.
[0033] Please refer to Figure 1 This embodiment provides a curtain structure 100 including a base fabric layer 10 and an organic silicon layer 20 . The number of the organic silicon layers 20 is two. The two organic silicon layers 20 are respectively arranged on both sides of the base fabric layer 10 and are stacked with the base fabric layer 10 .
[0034] In this embodiment, the screen structure 100 is applied to the interior of a car for projection while the car is driving. In other embodiments, the screen structure 100 can also be applied to a home scene or a work scene, which is not specifically limited here.
[0035] Specifically, the vehicle-mounted curtain in the prior art generally adopts a composite structure of a base fabric and single-sided silicone. Generally speaking, the material coated on the surface of the base fabric is liquid silicone, which needs to be cured by platinum reaction. The curing process of the liquid silicone needs to be placed in an oven for baking; after the silicone is coated on the base fabric, it is placed in an oven for baking. During the baking process, the volume of the silicone will shrink, while the volume of the base fabric remains almost unchanged. Therefore, after the silicone is cured, due to the large shrinkage of the silicone, the silicone layer and the base fabric layer will produce internal stress, and the curtain will curl in the direction of the silicone, thereby producing a curling phenomenon. In order to solve the above technical problems, when the curtain structure 100 provided in this embodiment is used, both sides of the base fabric layer 10 are provided with silicone layers 20, and the silicone layer 20 and the base fabric layer 10 are stacked. Since liquid silicone needs to be heated to solidify, the volume of silicone will shrink after being heated, while the volume of the base fabric layer 10 remains almost unchanged. The silicone layer 20 after shrinking will generate internal stress with the base fabric layer 10, causing the screen to curl in the direction of the silicone. The silicone layer 20 is arranged on both sides of the base fabric layer 10, so that the silicone layer 20 on both sides of the base fabric layer 10 can generate internal stress with the base fabric layer 10, and the generated internal stress is opposite to the thickness direction of the base fabric layer 10, so that the internal stress on both sides offsets each other, thereby preventing the screen from curling. The screen structure 100 can prevent the screen from curling when in use, ensure the normal use of the screen, and thus ensure the normal use of the projection.
[0036] In this embodiment, the thickness of the two organic silicon layers 20 is consistent. The thickness of the organic silicon layers 20 on both sides of the base fabric layer 10 is consistent, so that during the baking process, the shrinkage deformation of the two organic silicon layers 20 is consistent, and the internal stress generated by the two organic silicon layers 20 and the base fabric layer 10 is consistent, ensuring that the internal stresses on both sides of the base fabric layer 10 can offset each other, thereby avoiding the curling phenomenon of the curtain structure 100.
[0037] Specifically, the thickness of the organic silicon layer 20 ranges from 0.1 mm to 0.3 mm. In this embodiment, the thickness of the organic silicon layer 20 is 0.2 mm. In other embodiments, the thickness of the organic silicon layer 20 can also be 0.1 mm, 0.15 mm, 0.3 mm, etc., which is not specifically limited here.
[0038] In this embodiment, the thickness of the organic silicon layer 20 is greater than the thickness of the base fabric layer 10. Specifically, the thickness of the base fabric layer 10 ranges from 0.1 mm to 0.3 mm. In this embodiment, the thickness of the base fabric layer 10 is 0.1 mm. In other embodiments, the thickness of the base fabric layer 10 may also be 0.18 mm, 0.2 mm or 0.3 mm, which is not specifically limited here.
[0039] Furthermore, in order to ensure the clarity of the screen structure 100 during projection, the screen structure 100 provided in this embodiment includes an isolation layer 30, which is disposed on the side of the organic silicon layer 20 away from the base fabric layer 10. Specifically, the isolation layer 30 is a skin-feeling oil layer.
[0040] In this embodiment, skin-feeling oil is sprayed on the side of the organic silicone layer 20 away from the base fabric layer 10, thereby improving the smoothness of the surface of the organic silicone layer 20. At the same time, the skin-feeling oil can form a thin film on the surface of the organic silicone layer 20, thereby isolating the silicone from contact with dust in the air and preventing dust from adhering to the surface of the organic silicone layer 20, thereby affecting the clarity of the projected image.
[0041] It should also be noted that the screen structure 100 further includes a surface microstructure, which is disposed on a side of at least one organic silicon layer 20 away from the base fabric layer 10. The surface microstructure is disposed on the surface of the organic silicon layer 20 close to the projector, and the surface microstructure can converge the incident light, thereby improving the gain of the screen and ensuring a clear projection image.
[0042] Specifically, the surface microstructure is a concave structure arranged toward the base fabric layer 10, and the shape of the concave structure is a quadrangular pyramid structure and / or a triangular pyramid structure. The bottom surface of the quadrangular pyramid structure and / or the triangular pyramid structure is located on the surface of the side of the organic silicon layer 20 away from the base fabric layer 10, and the vertex of the concave structure is located in the organic silicon layer 20.
[0043] In this embodiment, the surface microstructure adopts a quadrangular pyramid structure, and the surface microstructure includes multiple reflective surfaces. When light is emitted to the surface of the organic silicon layer, the incident light is reflected multiple times on the multiple reflective surfaces and then emitted, so that more emitted light converges to the center of the screen, so that the viewer can see more light, thereby improving the visual effect. In other embodiments, the surface microstructure can also adopt other multi-faceted structures, which are not specifically limited here.
[0044] In this embodiment, the base fabric layer 10 includes glass fiber cloth. More preferably, the base fabric layer 10 can also be made of conventional heat-resistant fabrics such as polycarbonate and polyester. Since the curtain needs to be placed in an oven for baking during the coating process, and the baking temperature is generally below 110°C, it is necessary to use a heat-resistant fabric above 150°C to avoid failure of the curtain structure 100 under high and low temperature conditions, thereby affecting the normal operation of the curtain structure 100. Compared with ordinary household curtains in the prior art, the curtain structure 100 provided in this embodiment has more stable performance and is more convenient to use.
[0045] Furthermore, when the curtain is subjected to a pulling force, the base fabric layer 10 can withstand the pulling force, thereby ensuring that the surface of the organic silicon layer 20 will not be deformed under the action of the pulling force.
[0046] The screen structure 100 and the projection device provided in this embodiment have at least the following advantages:
[0047] The vehicle-mounted screen in the prior art generally adopts a composite structure of a base fabric and single-sided silicone. Generally speaking, the material coated on the surface of the base fabric is liquid silicone, which needs to be cured by platinum reaction. The curing process of the liquid silicone needs to be placed in an oven for baking. After the silicone is coated on the base fabric, it is placed in an oven for baking. During the baking process, the volume of the silicone will shrink, while the volume of the base fabric remains almost unchanged. Therefore, after the silicone is cured, due to the large shrinkage of the silicone, the silicone layer and the base fabric layer will produce internal stress, and the curtain will curl in the direction of the silicone, thereby producing a curling phenomenon. In order to solve the above technical problems, when the curtain structure 100 provided in this embodiment is used, both sides of the base fabric layer 10 are provided with silicone layers 20, and the silicone layer 20 and the base fabric layer 10 are stacked. Since liquid silicone needs to be heated to solidify, the volume of silicone will shrink after being heated, while the volume of the base fabric layer 10 remains almost unchanged. The silicone layer 20 after shrinking will generate internal stress with the base fabric layer 10, causing the screen to curl in the direction of the silicone. The silicone layer 20 is arranged on both sides of the base fabric layer 10, so that the silicone layer 20 on both sides of the base fabric layer 10 can generate internal stress with the base fabric layer 10, and the generated internal stress is opposite to the thickness direction of the base fabric layer 10, so that the internal stress on both sides offsets each other, thereby preventing the screen from curling. The screen structure 100 can prevent the screen from curling when in use, ensure the normal use of the screen, and thus ensure the normal use of the projection.
[0048] The screen structure 100 in this embodiment further includes an isolation layer 30, which is disposed on the side of the organic silicon layer 20 away from the base fabric layer 10. The isolation layer 30 can improve the smoothness of the surface of the organic silicon layer 20. Moreover, the isolation layer 30 can form a protection on the surface of the organic silicon layer 20, thereby isolating the silica gel from contacting with dust in the air, and preventing dust from adhering to the surface of the organic silicon layer 20, thereby affecting the clarity of the projected image.
[0049] Furthermore, in order to ensure the clarity of the image during the projection process of the screen structure 100, the screen structure 100 also includes a surface microstructure, which is arranged on the surface of the silicone layer 20 close to the projector. The surface microstructure includes multiple reflective surfaces. When light is emitted to the surface of the silicone layer 20, the incident light is reflected multiple times on the multiple reflective surfaces and then emitted, so that more outgoing light converges to the center of the screen, allowing the viewer to see more light, thereby improving the visual effect.
[0050] In summary, the embodiment of the utility model provides a curtain structure 100, which includes a base fabric layer 10 and an organic silicon layer 20. The number of the organic silicon layers 20 is two layers, and the two layers of organic silicon layers 20 are respectively arranged on both sides of the base fabric layer 10 and stacked with the base fabric layer 10. When the curtain structure 100 is in use, the organic silicon layers 20 are arranged on both sides of the base fabric layer 10, and the organic silicon layers 20 and the base fabric layer 10 are stacked. Since liquid silicone needs to be heated to solidify, the volume of silicone will shrink after being heated, while the volume of the base fabric layer 10 remains almost unchanged. The silicone layer 20 after shrinking will generate internal stress with the base fabric layer 10, causing the screen to curl in the direction of the silicone. The silicone layer 20 is arranged on both sides of the base fabric layer 10, so that the silicone layer 20 on both sides of the base fabric layer 10 can generate internal stress with the base fabric layer 10, and the generated internal stress is opposite to the thickness direction of the base fabric layer 10, so that the internal stress on both sides offsets each other, thereby preventing the screen from curling. The screen structure 100 can prevent the screen from curling when in use, ensure the normal use of the screen, and thus ensure the normal use of the projection.
[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
