[0027] Among them, the top of flip mirror body 2 is pre-buried with metal sheet 6 and magnetic attraction assembly 5 magnetic attraction adsorption, to realize the stable fixation of protective cover 3.

[0028] Concave part 30 sticks to the forehead of wearer, prevents foreign matter or ultraviolet from entering eye area from the top of forehead, simultaneously guides forehead sweat to both sides, avoids flowing into eye and affects sight. Concave part 30 is in the whole recessed curved surface shape, to adapt the arc of human forehead, is located in the side of protective cover 3 close to the forehead of wearer, directly contacts forehead.

[0029] Connecting part 31 is used to connect concave part 30 and elastic clamping sleeve 4, plays the role of force transmission and fixed elastic clamping sleeve 4, simultaneously covers the top of flip mirror body 2, enhances the protection to the top of glasses. Connecting part 31 is usually long strip-shaped plate structure, one end is integrally formed with concave part 30, and the other end is connected with flip mirror body 2 through elastic clamping sleeve 4.

[0030] The elastic clamping sleeve 4 is detachably fixed at the top of the flip lens body 2, and is adapted to the flip lens body 2 of different thicknesses through elastic deformation, and is stably adsorbed to the flip lens body 2 by using the internal magnetic adsorption assembly 5. The elastic clamping sleeve 4 is a hollow sleeve structure, which can be in the shape of "C" or similar to the shape of a clip, and can embrace the top of the flip lens body 2. The elastic clamping sleeve 4 can be made of plastic or rubber material with elasticity to ensure good elastic deformation capability.

[0032] Embodiment 2:

[0033] The embodiment provides a protective device for glasses, which has the following technical features in addition to the technical solutions of the above embodiments.

[0034] The inner wall of the elastic clamping sleeve 4 is coated with a soft silica gel layer 7 for adapting to the main lens frame 1 of different thicknesses.

[0035] The soft silica gel layer 7 is used to adapt to the main lens frame 1 of different thicknesses, to enhance the friction and contact stability between the elastic clamping sleeve 4 and the main lens frame 1, and to protect the surface of the main lens frame 1 from being scratched. The soft silica gel layer 7 is a layer of silica gel material uniformly attached to the inner wall of the elastic clamping sleeve 4, which is completely matched with the shape of the inner wall of the elastic clamping sleeve 4 and directly contacts the main lens frame 1. The soft silica gel layer 7 is made of soft, anti-skid and elastic silica gel material, such as food-grade silica gel, which has good flexibility, wear resistance and chemical stability. The soft silica gel layer 7 can be tightly attached to the inner wall of the elastic clamping sleeve 4 by coating or bonding process, to ensure that it will not fall off during long-term use.

[0036] Embodiment 3:

[0037] The embodiment provides a protective device for glasses, which has the following technical features in addition to the technical solutions of the above embodiments.

[0038] The concave part 30 of the protective cover 3 is provided with air permeable holes 8 arranged in a honeycomb array, and the inner wall of the air permeable hole 8 is coated with a hydrophobic coating.

[0039] The air permeable holes 8 arranged in a honeycomb array are arranged on the concave part 30 of the protective cover 3, which effectively solves the problem of stuffiness commonly existing in traditional protective covers 3. The honeycomb distribution mode maximizes the ventilation area while ensuring the structural strength of the concave part 30, so that external air can smoothly flow into the interior of the protective cover 3, and timely take away the heat and moisture generated by the human body temperature and the wearing environment, thereby significantly improving the comfort of the wearer.

[0040] The inner wall of the air hole 8 is coated with a hydrophobic coating, which is to prevent the intrusion of liquid on the basis of achieving good air permeability. Whether it is the natural secretion of sweat on the forehead or the rainwater that may be encountered outdoors, when it comes into contact with the inner wall of the air hole 8 coated with a hydrophobic coating, it will condense into water droplets due to the special surface tension characteristics of the coating, and roll off under the action of gravity or air flow, thereby avoiding the liquid from penetrating into the protective cover 3 through the air hole 8, interfering with the wearer's vision or causing damage to the glasses, and comprehensively enhancing the practicality and reliability of the protective device.

[0041] Embodiment 4:

[0042] The protective device for glasses provided in this embodiment has the following technical features in addition to the technical solutions of the above embodiments.

[0043] The magnetic attraction assembly 5 includes at least two pairs of neodymium magnets 50 symmetrically distributed on the inner wall of the elastic clamping sleeve 4. The magnetic poles of each pair of neodymium magnets 50 are opposite to each other to enhance the adsorption stability.

[0044] The neodymium magnets 50 are used to provide strong magnetic force to overcome external forces that may cause the protective device to fall off, such as vibration during exercise, wind force, etc., to ensure that the protective cover 3 is always firmly installed on the glasses. The neodymium magnets 50 are commonly in the form of blocks or sheets, and are symmetrically distributed in pairs on the inner wall of the elastic clamping sleeve 4. Each neodymium magnet 50 corresponds to a metal sheet 6, and the magnetic poles of each pair of neodymium magnets 50 are opposite to each other. The neodymium magnets 50 can be connected to the inner wall of the elastic clamping sleeve 4 by means of gluing, inlaying or buckling, etc., to ensure firm fixation.

[0045] This embodiment adopts at least two pairs of neodymium magnets 50 symmetrically distributed on the inner wall of the elastic clamping sleeve 4, and the magnetic poles of each pair of neodymium magnets 50 are opposite to each other. This design has multiple purposes. From the perspective of enhancing adsorption stability, multiple pairs of neodymium magnets 50 work together to generate a stronger and more evenly distributed magnetic field. When interacting with the metal sheet 6 embedded at the top of the flip-up lens body 2, it can exert adsorption force on a larger area, avoiding the shaking of the protective device caused by uneven local stress. The layout of opposite magnetic poles makes the magnetic fields interweave with each other, forming a complementary and balanced state, further stabilizing the adsorption relationship with the metal sheet 6. Even in complex use environments, such as when the wearer is in a state of motion and is subjected to external forces such as vibration and jolt, this design can effectively maintain the firmness of the protective device, ensuring that it does not easily fall off, thereby providing continuous and reliable protection for the wearer, greatly improving the performance of the protective device in actual use.

[0046] Embodiment 5:

[0047] The protective device for glasses provided in this embodiment has the following technical features in addition to the technical solutions of the above embodiments.

[0048] The side wall of the elastic clamping sleeve 4 is provided with an air guide groove 9 for discharging air to avoid negative pressure interference during clamping.

[0049] The air guide groove 9 provides a discharge channel for air when the elastic clamping sleeve 4 clamps the flip lens body 2, avoiding negative pressure interference caused by air compression. The air guide groove 9 is an elongated slot structure machined on the side wall of the elastic clamping sleeve 4, extending through the side wall of the elastic clamping sleeve 4 for a certain length, generally in the form of a long strip. The cross-sectional shape of the slot can be rectangular, semicircular or trapezoidal, etc. to facilitate air flow and not affect the structural strength of the elastic clamping sleeve 4. The air guide groove 9 is arranged on the side wall of the elastic clamping sleeve 4 and is generally symmetrically distributed near the opening end of the elastic clamping sleeve 4, so as to quickly discharge air during clamping.

[0050] When the elastic clamping sleeve 4 clamps the top of the flip lens body 2, the internal space will change due to elastic deformation. If there is no air guide groove 9, as the clamping action proceeds, the internal air will be compressed, forming a local negative pressure environment. This negative pressure interference can cause many adverse effects. On the one hand, it will make the fit between the elastic clamping sleeve 4 and the flip lens body 2 unstable, making it difficult to achieve tight and stable clamping, and the protective device is easy to shift due to loosening during use. On the other hand, the additional resistance generated by negative pressure will increase the difficulty of the user to install and disassemble the protective device. The presence of the air guide groove 9 provides a discharge channel for air. During the clamping process of the elastic clamping sleeve 4, air can smoothly pass through the air guide groove 9 and be discharged, avoiding the formation of negative pressure, thereby ensuring that the elastic clamping sleeve 4 can smoothly and efficiently complete the clamping operation of the flip lens body 2, making the installation of the protective device more convenient, the connection more firm, and significantly improving the user experience and practicality of the protective device.

[0051] Embodiment 6:

[0052] The protective device for glasses provided in this embodiment has the following technical features in addition to the technical solutions of the above embodiments.

[0053] The concave part 30 of the protective cover 3 is covered with an antibacterial silicone layer 10 on the forehead contact surface.

[0054] The antibacterial silicone layer 10 is used to reduce bacterial reproduction caused by long-term wearing and forehead sweating, reduce the risk of skin infection, and improve wearing comfort. The antibacterial silicone layer 10 is a layer of silicone material uniformly covering the forehead contact surface of the concave part 30, containing an antibacterial agent component. The antibacterial silicone layer 10 has the same surface shape as the concave part 30 and the forehead, completely covering the contact area. The antibacterial silicone layer 10 can be fixed on the surface of the concave part 30 by bonding or compounding when the material of the concave part 30 is formed.

[0055] The contact surface between the concave part 30 of the protective cover 3 and the forehead is covered with an antibacterial silica gel layer 10, which has multiple key purposes. From the perspective of health and hygiene, the forehead is prone to sweating during daily wear, and the warm and humid environment creates a breeding ground for bacteria. The antibacterial ingredients in the antibacterial silica gel layer 10, such as silver ions, can effectively inhibit the growth and reproduction of bacteria, greatly reducing the risk of skin infection, allergy and other problems caused by bacteria, and protecting the skin health of the wearer. From the perspective of wearing experience, the silica gel material is soft and elastic, which can significantly reduce the feeling of oppression and friction caused by long-term wear when it is attached to the forehead, avoiding skin marks and swelling, and improving the comfort of wearing. In addition, this design can also prolong the service life of the protective device to some extent. Bacterial growth often accelerates the aging and damage of materials, and the antibacterial silica gel layer 10 reduces such erosion, ensuring that the protective device can stably play a protective role for a long time, and improving the practicality and user satisfaction of the product.

[0056] Embodiment 7:

[0057] The protective device of the glasses provided in this embodiment has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0058] The connection part 31 and the concave part 30 are provided with a bendable elastic transition area 11, which is used to keep the concave part 30 of the protective cover 3 in contact with the forehead when the flip cover lens body 2 is flipped.

[0059] The elastic transition area 11 ensures that the concave part 30 can stably fit the forehead during the use of the flip cover lens body 2, without affecting the protection effect and wearing comfort. The elastic transition area 11 is generally in the shape of a transition between the concave part 30 and the connection part 31, and is usually smooth to ensure smoothness when bending. The elastic transition area 11 is arranged at the junction of the connection part 31 and the concave part 30. The elastic transition area 11 is usually made of materials with good elasticity, such as rubber or elastic plastic, to realize the function of being bendable. The elastic transition area 11, the concave part 30 and the connection part 31 can be connected by one-piece molding or firm bonding to ensure the integrity of the structure during bending.

[0060] The above-mentioned embodiments are only preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made in accordance with the structure, shape and principle of the present application should be covered within the protection scope of the present application.
