Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarizer technology, specifically to a low-reflectivity polarizer assembly. Background Technology
[0002] Low-reflectivity polarizer assemblies are optical components widely used in display technology, optical instruments, and photographic equipment. Their main function is to filter and adjust the propagation direction of light through the principle of polarization, thereby controlling the reflection, transmission, and other optical properties of light. Low-reflectivity polarizers involve how to reduce light reflection during the surface design and manufacturing process of the polarizer to improve the overall performance of the system. A major challenge in the transportation of low-reflectivity polarizer assemblies is how to effectively protect them from the effects of external environment (such as vibration, shock, and temperature and humidity changes) on their performance and structure. As high-precision optical components, any physical damage or surface contamination of the polarizer assembly will affect its optical performance, especially reflectivity and transmittance. Therefore, the technical background of protecting it during transportation is crucial.
[0003] Nowadays, most goods are simply packaged in cardboard boxes during transportation, often without considering the standardization of packaging or the characteristics of the goods. This casual transportation method can easily lead to collisions, squeezing, or other damage to goods during transportation, and may even affect the appearance and quality of the products. Therefore, adopting more professional packaging methods and taking into account the various risks that may be encountered during transportation has become a necessary measure to ensure the safe transportation of goods.

[0015] As attached Figure 1 To be continued Figure 5 As shown: This embodiment provides a low-reflectivity polarizer assembly, including a housing 1. First sliding grooves 2 are formed on both sides of the inner cavity of the housing 1. First sliding rods 3 are fixedly connected to the inner cavities of both first sliding grooves 2. A first spring 4 is sleeved on one end of each first sliding rod 3, and a first sliding frame 5 is slidably connected to the surface of the first sliding rod 3. One side of the first sliding frame 5 is fixedly connected to the first spring 4. A first rotating rod 6 is rotatably connected to the inner cavity of the first sliding frame 5, and a first fixed frame 7 is rotatably connected to the other end of the first rotating rod 6. A second sliding groove 8 is formed in the middle of the inner cavity of the housing 1. The inner cavity of the second sliding groove 8 is fixedly connected to... A second sliding rod 9 is connected, and a second sliding frame 10 is slidably connected to both ends of the second sliding rod 9. A second spring 11 is fixedly connected to the opposite side of the two second sliding frames 10. The second spring 11 is sleeved on the surface of the second sliding rod 9. A second rotating rod 12 is rotatably connected to the top of the two second sliding frames 10. A second fixed frame 13 is rotatably connected to the other end of the second rotating rod 12. A fixed box 14 is fixedly connected to the top of the first fixed frame 7 and the second fixed frame 13. A protective pad 15 is fixedly connected to the inner cavity of the fixed box 14. A polarizer body 16 is provided in the inner cavity of the protective pad 15.
[0016] Specifically, the polarizer body 16 includes a substrate layer 161 disposed in the inner cavity of the protective pad 15, a phase compensation layer 162 fixedly connected to the surface of the substrate layer 161, a polarizing layer 163 fixedly connected to the surface of the phase compensation layer 162, an anti-glare layer 164 fixedly connected to the surface of the polarizing layer 163, and a low-reflection layer 165 fixedly connected to the surface of the anti-glare layer 164.
[0017] In this embodiment: through the setting of the polarizer body 16, the material of the substrate layer 161 is, but not limited to, PET or TAC, serving as a basic support layer to provide mechanical strength and light transmittance, ensuring the overall structural stability of the polarizer. The material of the phase compensation layer 162 is, but not limited to, liquid crystal polymer, located between the substrate layer and the polarizing layer, converting linearly polarized light into circularly polarized light, improving the viewing angle symmetry of the OLED display, and reducing color shift. The material of the polarizing layer 163 is, but not limited to, PVA, serving as the core polarizing functional layer, allowing only polarized light in a specific direction to pass through, thus achieving light polarization. The material of the anti-glare layer 164 is, but not limited to, silica sol particles coated with liquid and cured, reducing ambient light reflection through surface scattering structure, achieving a haze of ≥95%, effectively suppressing glare, and improving visibility in strong light environments. The material of the low-reflection layer 165 is, but not limited to, acrylate prepolymer, which, through multi-layer refractive index matching, reduces reflectivity to ≤0.3%, significantly reducing light reflection loss.
[0018] Specifically, dampers 17 are fixedly connected to the four corners of the inner cavity of the outer shell 1, and the top of the dampers 17 is fixedly connected to the bottom of the fixed box 14.
[0019] In this embodiment, the damper 17 effectively reduces the generated vibration by absorbing and dissipating external vibration energy, thereby reducing the impact between the fixed box 14 and the outer shell 1 and effectively reducing the vibration amplitude.
[0020] Specifically, a number of connecting rods 18 are fixedly connected to the outer wall of the fixed box 14. One end of each connecting rod 18 extends through to the outside of the outer shell 1. A third spring 19 is sleeved on the surface of the connecting rod 18 and is located between the outer shell 1 and the connecting rod 18.
[0021] In this embodiment: through the cooperation of the connecting rod 18 and the third spring 19, when shaking or vibration occurs, the connecting rod 18 and the third spring 19 work together to form an elastic support, effectively dispersing and absorbing external impact and vibration energy, greatly reducing the propagation of vibration, thereby ensuring the stability and safety of the fixed box 14 under various working conditions.
[0022] Specifically, the bottom of the outer casing 1 is fixedly connected to two support seats 20, which are arranged symmetrically.
[0023] In this embodiment, the support base 20 effectively provides stable support, maintaining an appropriate gap between the outer shell 1 and the ground, avoiding direct contact, which not only reduces frictional wear but also effectively reduces wear caused by long-term use, extending the service life of the outer shell 1.
[0024] The working principle and usage process of this utility model: The user places several processed polarizer bodies 16 stacked inside the cavity of the fixing box 14. The polarizer bodies 16 are in close contact with the protective pad 15. The protective pad 15 is made of, but is not limited to, rubber material, which can not only effectively increase friction but also provide necessary protection. Thus, during the long-term transportation of the polarizer bodies 16, the protective pad 15 plays the role of the first protective barrier. During transportation, bumps and vibrations are inevitable. At this time, the fixing box 14, the protective pad 15, and the polarizer bodies 16 will respond together and shake to a certain extent. The vibration causes the surrounding area and the bottom to be squeezed. First, the fixing box 14 will drive the connecting rod 18 to slide. The surface of the connecting rod 18 is fitted with a third spring 19. Through its elasticity, the amplitude of the shaking to the surrounding area is reduced, effectively reducing the transmission of vibration. Then, the fixing box 14 applies pressure to the second fixing frame 13 and the first fixing frame 7. The pressure causes the second fixed frame 13 to drive the second rotating rod 12 to rotate. The second rotating rod 12 is rotatably connected to the second sliding frame 10, causing the second sliding frame 10 to slide along the surface of the second sliding rod 9. At this time, the second sliding rod 9 applies a compressive force to the second spring 11. With the help of the elastic recovery of the second spring 11, a counterforce is generated, which counteracts the compressive force, thereby further mitigating vibration. Similarly, the first fixed frame 7 drives the first rotating rod 6 to rotate. The first rotating rod 6 is rotatably connected to the first sliding frame 5, causing the first sliding frame 5 to slide on the surface of the first sliding rod 3. The first sliding frame 5 applies a compressive force to the first spring 4, and through the elastic recovery of the first spring 4, a reaction force is generated, further reducing vibration. Through the coordinated action of the above multiple vibration reduction mechanisms, the polarizer body 16 is effectively protected during transportation, avoiding damage caused by vibration and impact, reducing the impact of vibration during transportation, thereby reducing economic losses caused by damage, and improving transportation efficiency and safety.
