Description

Technical Field

[0001] This utility model relates to the field of eyeglasses equipment technology, and in particular to an impact-resistant colored polarized lens. Background Technology

[0002] Polarizing filters, as a type of functional optical lens, can effectively eliminate glare and reflected light. They are widely used in driving, outdoor sports, photography, and certain industrial environments, providing users with a clearer and more comfortable visual experience.

[0003] With the diversification of market demand, modern polarizing lenses are no longer satisfied with a single polarizing function. They often integrate multiple optical properties such as UV protection, blue light protection, and photochromic properties through lens stacking or coating technology, thus developing into colored or multifunctional polarizing lenses.

[0004] However, polarized lenses, especially composite lenses with integrated multi-layer functional coatings, are typically quite delicate and brittle. In outdoor sports or industrial settings, eyeglasses are frequently exposed to the risk of accidental drops or impacts. Existing polarized lens products often prioritize optical performance and wearing comfort in their structural design, with lenses typically mounted directly within the frame. This structure lacks specialized impact-resistant design; when subjected to external force, the impact bypasses the frame and acts directly on the lens edge or surface, making the lens highly susceptible to breakage and shattering. This not only shortens the product's lifespan but also poses a safety hazard, as broken lenses can potentially injure the user's eyes.

[0005] Therefore, this invention proposes an impact-resistant colored polarizing mirror to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an impact-resistant colored polarizing lens, which aims to improve the existing technology, which lacks impact-resistant buffer design, is prone to lens damage and breakage, and has limited optical functions and cannot adapt to various complex lighting environments.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an impact-resistant colored polarizing mirror, comprising a polarizing mirror, a protective mechanism, and an optical adjustment mechanism; The protective mechanism covers the outer periphery of the polarizer, and the optical adjustment mechanism is stacked on the front or rear side of the polarizer. The protective mechanism includes a first protective shell, a second protective shell, a rubber pad, a mounting groove, and a mounting post. Furthermore, the second protective shell and the first protective shell are combined by snap-fit ​​or screw-fit to form a lens cavity for accommodating the polarizing mirror. The rubber pad is fixedly connected to the inner wall of the lens cavity and abuts against the edge of the polarizing mirror. The mounting groove is formed in the first protective shell, and the mounting post is fixedly connected to the second protective shell. The mounting post is inserted into the mounting groove to achieve a limiting connection between the first protective shell and the second protective shell. Preferably, the rubber pad has a ring structure and conforms to the edge contour of the polarizing mirror; Preferably, there are at least two sets of mounting slots and mounting posts, and they are spaced apart along the circumference of the protection mechanism; Preferably, the mounting post and the mounting groove are interference-fitted; Preferably, the optical adjustment mechanism is detachably mounted on the protective mechanism; Preferably, the optical adjustment mechanism includes an anti-ultraviolet lens; Preferably, the optical adjustment mechanism further includes a blue light blocking lens, which is stacked on one side of the ultraviolet-protecting lens; Preferably, the optical adjustment mechanism further includes a photochromic lens, which is stacked on one side of the blue light blocking lens.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem that the polarizing mirror in the prior art is simple in structure and lacks buffer, making the mirror easy to break when subjected to external impact. It achieves the combination of hard shell protection and soft pad energy absorption, and significantly improves the overall impact resistance of the device.

[0009] 2. This utility model, by setting up an optical adjustment mechanism, which includes at least one or more combinations of anti-ultraviolet lenses, anti-blue light lenses, and photochromic lenses, and stacking the optical adjustment mechanism with a polarizing lens, solves the problem that the existing polarizing lens has a single optical function and cannot adapt to various complex usage scenarios such as anti-ultraviolet, anti-blue light, or changes in light intensity. It enriches the optical functions of glasses and improves the visual comfort and protection of users in different lighting environments.

[0010] 3. This utility model achieves structural stability and reliability by detachably installing the optical adjustment mechanism onto the protective mechanism, while the first protective shell and the second protective shell of the protective mechanism are connected and limited by the mounting post and the mounting groove. This makes it convenient for users to flexibly assemble or replace functional lenses according to actual needs, and improves the ease of use and scene adaptability. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-4 An embodiment of this utility model is provided: an impact-resistant colored polarizing mirror, including a polarizing mirror 1, a protective mechanism 2 and an optical adjustment mechanism 3. The polarizing mirror 1 serves as the base lens, the protective mechanism 2 covers the outer periphery of the polarizing mirror 1 to provide impact protection for the polarizing mirror 1, and the optical adjustment mechanism 3 is stacked on the front or rear side of the polarizing mirror 1 to enrich the optical performance. Specifically, the protective mechanism 2 includes a first protective shell 204, a second protective shell 205, a rubber pad 201, a mounting groove 202, and a mounting post 203. The first protective shell 204 and the second protective shell 205 are snapped or screwed together to form a lens cavity for accommodating the polarizer 1. The rubber pad 201 is fixedly connected to the inner wall of the lens cavity and abuts against the edge of the polarizer 1 to provide cushioning. The mounting groove 202 is opened in the first protective shell 204. The mounting post 203 is fixedly connected to the second protective shell 205 and is inserted into the mounting groove 202 to achieve a limiting connection between the first protective shell 204 and the second protective shell 205. The rubber pad 201 has a ring-shaped structure, and its shape conforms to the edge contour of the polarizer 1. This design allows the rubber pad 201 to evenly distribute pressure when subjected to impact, avoiding stress concentration. To enhance the stability of the connection between the first protective shell 204 and the second protective shell 205, at least two sets of mounting grooves 202 and mounting posts 203 are provided, spaced apart along the circumference of the protective mechanism 2. In one specific assembly method, the mounting posts 203 and the mounting grooves 202 are interference-fitted. This tight fit increases the connection strength and impact resistance of the first protective shell 204 and the second protective shell 205, based on snap-fit ​​or screw-fit. The optical adjustment mechanism 3 is described in detail below. 3 is detachably installed on the protective mechanism 2, for example, by means of a snap or magnetic attraction to fix it to the outside of the first protective shell 204 or the second protective shell 205. The optical adjustment mechanism 3 itself is a multi-layer lens combination structure. In this embodiment, the optical adjustment mechanism 3 includes an anti-ultraviolet lens 301 and an anti-blue light lens 302, which is stacked on one side of the anti-ultraviolet lens 301. The optical adjustment mechanism 3 also includes a photochromic lens 303, which is stacked on one side of the anti-blue light lens 302. Through this combination of multi-layer lenses, the present invention not only has the basic polarization function of the polarizer 1, but also provides a composite function of anti-ultraviolet, anti-blue light and automatic color change according to light. The first protective shell 204 and the second protective shell 205 are both injection molded from polycarbonate material. The rubber pad 201 is made of thermoplastic elastomer material. The optical adjustment mechanism 3 and the protective mechanism 2 are detachably installed using a magnetic structure. A magnet is fixedly connected to the edge frame of the optical adjustment mechanism 3. A ferromagnetic material sheet is correspondingly provided on the outer edge of the protective mechanism 2. The anti-ultraviolet lens 301, anti-blue light lens 302 and photochromic lens 303 in the optical adjustment mechanism 3 are integrally encapsulated into a composite lens module by means of optical adhesive bonding to ensure stable optical performance and reduce internal reflection.

[0015] Working principle: When the device is subjected to external impact, the impact force first acts on the first protective shell 204 and the second protective shell 205. Thanks to the limiting connection between the mounting groove 202 and the mounting post 203, the first protective shell 204 and the second protective shell 205 are firmly connected and together form a stable lens cavity to resist external force. The impact force is transmitted through the protective shell to the rubber pad 201 fixedly connected to the inner wall of the lens cavity. The rubber pad 201, as a ring structure, abuts against and fits the edge of the polarizer 1. The rubber pad 201 undergoes elastic deformation to absorb and buffer the impact energy, preventing the polarizer 1 from being directly damaged by force. In terms of optical adjustment, the polarizer 1 realizes the basic polarization function. The optical adjustment mechanism 3 is stacked on the front or back of the polarizer 1. The user can install the optical adjustment mechanism 3 by a detachable installation method (e.g., magnetic attachment). When the optical adjustment mechanism 3 includes an anti-ultraviolet lens 301, the device can filter ultraviolet rays. When the optical adjustment mechanism 3 further includes a stacked anti-blue light lens 302, the device can block blue light. When the photochromic lens 303 is used, the device can automatically adjust the light transmittance according to the intensity of the external light.
