[0002] When vehicles are parked outdoors, weatherstripping is susceptible to pecking or chewing by birds or other animals, leading to a decline in its sealing performance. Common protective methods include: physical barriers, such as covering the weatherstripping with a metal mesh to prevent animal contact, but due to the narrow gap between the glass and sheet metal, the clips are difficult to secure during installation; optical repellency, which involves coating the weatherstripping with glass microbeads or metal powder that reflect specific wavelengths of light to repel animals, but animals can easily adapt, and the effect weakens over time; chemical repellency, which involves applying bittering agents or other chemical repellents to the surface of the weatherstripping, but this method has the problems of short shelf life and environmental pollution; and electromagnetic repellency, which involves emitting electromagnetic waves of specific frequencies to interfere with birds' navigation systems, but this method consumes a lot of power.

[0019] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Current optical deterrents repel animals by coating them with glass microbeads or metal powder that reflect specific wavelengths of light. However, animals easily adapt, and the effect diminishes over time. In this embodiment, a movable magnet 3 is used to change the direction of the magnetic field, thereby moving the magnetic edging 2 on the sealing strip 7. This alters the light reflected by the optical lens 1, making it harder for animals to adapt and protecting the sealing strip.

[0021] Please refer to Figures 1 to 3 As shown, the present invention provides an optical driving device, which includes an optical lens 1, a magnetic edging 2, and a magnet 3 for driving the magnetic edging 2. The optical lens 1 is embedded in the magnetic edging 2.

[0022] Working principle: Based on the Bragg-Snell equation:

[0023] Where is the reflection wavelength, d is the lattice period, and n is the lattice period. eff For effective refractive index, The angle of incidence is given. The formula shows that changing the angle of incidence alters the wavelength of the reflected light. Therefore, by moving the magnet 3 to change the direction of the magnetic field, the magnetic edging 2 carrying the optical lens 1 can be moved, thereby changing the angle of incidence of light entering the optical lens 1. This causes the optical lens 1 to reflect light of different wavelengths, making it difficult for animals to adapt and thus protecting the sealing strip 7.

[0024] It is worth noting that the optical lens 1 is used to reflect light with wavelengths from 480nm to 680nm; and the magnet 3 can be an electromagnet or a permanent magnet.

[0025] In some embodiments, the optical lens 1 includes a substrate and a plurality of photonic crystals embedded therein. The optical lens 1 utilizes photonic crystals to reflect light, and the substrate carries the plurality of photonic crystals. The photonic crystal is a nanostructured material with a periodic dielectric constant distribution, whose core feature is the modulation of light propagation through Bragg diffraction. When the lattice constant of the periodic structure matches the visible light wavelength (380 nm to 780 nm), light of a specific wavelength is selectively reflected or transmitted, forming structural color.

[0026] It is worth noting that multiple photonic crystals are embedded on the substrate at different angles to achieve multi-angle light reflection. The substrate is preferably made of acrylic sheet or plexiglass.

[0027] In some implementations, please refer to Figure 3 As shown, an optical driving device also includes a motor 4, which drives the magnet 3 to rotate. By driving the magnet 3 to rotate via the motor 4, the direction of the magnetic field is continuously changed, thereby continuously causing the magnetic edging 2 to move accordingly.

[0028] It is worth noting that motor 4 can be replaced with other driving devices, such as a rotary cylinder.

[0029] In some embodiments, the magnetic edging 2 comprises a polyurethane body and a plurality of iron oxide particles embedded in the polyurethane body. The magnetic edging 2 is activated by the interaction between the iron oxide particles and the magnetic field surrounding the magnet 3.

[0030] Please refer to Figures 1 to 3 As shown, the present invention provides a glass assembly, including a glass 5 and a sealing strip 7 arranged along the edge contour of the glass 5. A magnet 3 is provided below the glass 5. A magnetic edging 2 is oscillatingly arranged on the sealing strip 7. An optical lens 1 is embedded in the magnetic edging 2. The magnet 3 is used to drive the magnetic edging 2 to oscillate on the sealing strip 7.

[0031] Working principle: A magnetic edging 2 with an optical lens 1 is added to the sealing strip 7. By using a movable magnet 3 to change the direction of the magnetic field, the magnetic edging 2 can be moved on the sealing strip 7, causing the light reflected by the optical lens 1 to change, making it difficult for animals to adapt and thus protecting the sealing strip 7.

[0032] In some implementations, please refer to Figure 1 As shown, the glass 5 is embedded in the sheet metal part 6 so that the sealing strip 7 is located between the glass 5 and the sheet metal part 6.

[0033] It is worth noting that the magnet 3 can also be set at the sheet metal part 6 to drive the magnetic edge 2 to swing on the sealing strip 7.

[0034] In some implementations, please refer to Figure 1 and Figure 4 As shown, a motor 4 is installed on the glass 5. The magnet 3 includes an active magnet 31 and a driven magnet 32 ​​spaced apart along the length and / or width of the glass 5. The motor 4 drives the active magnet 31 to rotate. The magnetic edging 2 on the sealing strip 7 is driven by the active magnet 31 and the driven magnet 32. When the motor 4 drives the active magnet 31 to rotate, the changing magnetic field also drives the driven magnet 32 ​​to rotate, so that the active magnet 31 and the driven magnet 32 ​​can drive the magnetic edging 2 to move together.

[0035] Preferably, the magnetic edging 2 on the sealing strip 7 is activated by a combination of an active magnet 31 and multiple driven magnets 32.

[0036] In some embodiments, the motor 4 is equipped with an independent battery, which can charge the vehicle while it is in motion and provide power to the motor 4 when the vehicle is off. The motor 4 is attached to the glass 5 using adhesive, double-sided tape, or similar methods.

[0037] In some implementations, please refer to Figure 5 As shown, multiple magnetic edgings 2 are spaced apart along the contour of the sealing strip 7. Multiple independent magnetic edgings 2 are used on the sealing strip 7 to ensure that the swing stroke of the magnetic edgings 2 is not affected when the magnetic field changes, and to avoid the magnetic edgings 2 being too long and subject to superposition of magnetic fields from different directions.

[0038] In some implementations, please refer to Figure 1 As shown, the aforementioned glass assembly also includes a sheet metal part 6. The sheet metal part 6 has a support portion 61 extending below the glass 5. A magnetic blocking plate 62 is provided on one end face of the support portion 61 facing the glass 5, and the magnet 3 is located between the glass 5 and the magnetic blocking plate 62. The sheet metal part 6, through the support portion 61, provides the magnetic blocking plate 62 below the magnet 3, using the magnetic blocking plate 62 to block the magnetic field and prevent the magnet 3 from being affected by the sheet metal part 6. Preferably, the magnetic blocking plate 62 is made of austenitic aluminum alloy.

[0039] In some implementations, please refer to Figure 2 As shown, the bottom of the magnetic edging 2 is hemispherical, and the sealing strip 7 has a mounting groove 71 that is interference-fitted with the bottom of the magnetic edging 2. The interference fit between the bottom of the magnetic edging 2 and the mounting groove 71 ensures the stability of the magnetic edging 2 on the sealing strip 7, while limiting the bottom of the magnetic edging 2 to be hemispherical, so that the magnetic edging 2 can swing on the sealing strip 7 when subjected to force.

[0040] In some implementations, please refer to Figure 1As shown, the installation height of the optical lens 1 is lower than that of the glass 5, the edge strip 51 of the glass 5, and the sheet metal part 6. This not only avoids exposing the optical lens 1 to the outside and affecting the overall appearance of the vehicle, but also prevents the optical lens 1 and the magnetic edge strip 2 from being exposed to the outside and creating wind resistance.

[0041] In some implementations, please refer to Figure 1 As shown, the sealing strip 7 includes a rigid part 72 and a flexible part 73 connected to each other. The sealing strip 7 is engaged with the edge of the glass 5 through the rigid part 72, and the sealing strip 7 abuts against the sheet metal part 6 using the flexible part 73 to form a seal. The magnetic edge 2 is provided on the flexible part 73 to prevent birds or other animals from pecking or gnawing on it. The rigid part 72 is preferably made of EPDM (ethylene propylene diene monomer rubber) with a Shore hardness of 80 to ensure the strength of the sealing strip 7. The flexible part 73 is preferably made of EPDM (ethylene propylene diene monomer rubber) with a Shore hardness of 60 to ensure that the sealing strip 7 does not produce abnormal noise when it overlaps with the sheet metal part 6.

[0042] In some implementations, please refer to Figure 1 As shown, a support strip 721 is provided inside the rigid part 72. The support strip 721 supports the rigid part 72 and prevents shrinkage during the production of the rigid part 72. The support strip 721 is preferably made of copper wire.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
