Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a fog-proof and scratch-proof composite coated lens. Background Art

[0002] With people's yearning for outdoor activities and love for extreme sports, a large number of protective equipment have emerged. Among them, the protection of eyes is particularly important. Some protective glasses play an important role in protecting eyes during sports. However, in an environment with a large temperature difference, the surface of the original resin lens is likely to adsorb water in the air due to the temperature difference and condense into tiny droplets on the lens surface to form fog. These fogs will refract and scatter light, change the optical properties of the lens, make the lens gradually opaque and thus affect the line of sight, which is very dangerous during outdoor sports and driving or cycling. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fog-proof and scratch-proof composite coated lens to solve the problem that the fog on the lens surface affects the line of sight and makes it dangerous to observe the surroundings as mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a fog-proof and scratch-proof composite coated lens, including a middle frame. The middle frame is designed as an arc-shaped cuboid, and an annular protrusion is arranged inside the middle frame. A positioning groove is arranged on the outer surface of the middle frame, and the positioning groove is located at the four corners of the middle frame. An inner lens is fixedly installed inside the annular protrusion, and a bayonet groove is arranged on the outer surface of the inner lens. A heating mechanism is arranged between the inner lens and the inside of the middle frame. By heating the lens through the heating mechanism, the temperature of the lens is increased to evaporate the water vapor on the outer surface, reducing or even eliminating the fogging condition.

[0005] Preferably, the heating mechanism includes: a heating film. The heating film is fixedly attached to the side surface of the inner lens, and the side surface of the inner lens is attached to the inner surface of the middle frame. The inner surface of the middle frame is attached to the inner surface of the heating film, and the heating film is made of transparent hollow material. The outer surface of one end of the heating film away from the bayonet groove is attached to a front lens, and the side surface of the front lens is aligned with the side surface of the middle frame.

[0006] By adopting the above technical solution, the heating film can be electrified to generate heat and conduct the heat to the front lens and the rear lens, so that the front lens and the rear lens made of glass can better absorb heat, reduce the temperature difference between the external temperature and the front lens and the rear lens, make the moisture in the air not easily condense on the outer surfaces of the front lens and the rear lens, and reduce the danger caused by the inability to see clearly.

[0007] Preferably, a metal contact is inlaid and installed on one side surface of the middle frame, and the metal contact is connected to the input wire of the heating film.

[0008] With the above technical solution, after the lens is installed inside the frame, electricity can be connected to the metal contact through the circuit inside the frame to supply power to the heating film, and at the same time, it is convenient to install the lens.

[0009] Preferably, a rear lens is fixedly attached to one side surface of the middle frame, and the rear lens is arc-shaped. The rear lens is a sheet made of glass, and an anti-scratch and wear-resistant coating is plated on the outer surface of the rear lens away from the middle frame. There is a filling layer between the rear lens and the inner lens, and the filling layer is filled with transparent resin.

[0010] With the above technical solution, the rear lens made of glass improves its anti-scratch and wear resistance. At the same time, through the transparent resin filled into the filling layer, the rear lens can be adhered to the middle frame more firmly, improving the impact resistance and drop resistance of the lens.

[0011] Preferably, a support strip is arranged on the outer surface of the rear lens, and the side surface of the support strip is attached to the outer surface of the inner lens, and the side surface of the support strip is attached to the side surface of the annular protrusion.

[0012] With the above technical solution, the rear lens can be positioned by inserting the support strip into the inside of the annular protrusion, so that the rear lens can be completely attached to the middle frame, and at the same time, the side surfaces of the middle frame and the rear lens are flush.

[0013] Preferably, an anti-scratch and wear-resistant coating is applied to the outer surface of the front lens, and a protruding block is fixedly installed on the outer surface of the front lens. The protruding block protrudes from the outer surface of the front lens, and the front lens is a sheet made of glass material.

[0014] With the above technical solution, through the protruding block on the outer surface of the front lens, the front lens cannot directly contact places such as the tabletop, reducing the probability of the front lens being scratched and abraded. At the same time, the glass material of the front lens can improve the anti-wear and anti-scratch properties and extend the service life of the lens.

[0015] Preferably, one end of the protruding block is attached to the positioning groove, the front lens is adhered to the middle frame, and the annular protrusion of the middle frame is engaged with the bayonet slot.

[0016] With the above technical solution, the front lens and the middle frame can be positioned by the engagement of the protruding block and the positioning groove, so that they will not be misaligned during adhesion. At the same time, the overall lens is composed of composite materials, so it is lighter in weight.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: the anti-fog and anti-scratch composite coating lens:

[0018] 1. Install the lens into the frame, supply power to the heating film through the metal contacts on the side surface of the middle frame, heat the heating film, raise the temperature of the rear lens and the front lens through the heating of the heating film, evaporate the water vapor on the surfaces of the heated rear lens and front lens, prevent the water vapor in the air from condensing on the outer surfaces of the rear lens and front lens, reduce or even eliminate the fog on the outer surfaces of the rear lens and front lens, and improve the safety of outdoor activities such as driving and cycling.

[0019] 2. Through the support strip, the rear lens can be automatically positioned after being inserted into the middle frame, so that the middle frame and the rear lens can fit accurately without gaps. At the same time, the lens and the middle frame are more firmly adhered by filling transparent resin in the filling layer. At the same time, the front lens can be positioned by the insertion of the protruding block and the positioning groove, so that there are no gaps after the front lens and the middle frame are adhered, and at the same time, the adhesion area is increased, making the middle frame and the front lens more firmly adhered, and improving the anti-drop and anti-impact capabilities of the lens.

[0020] 3. Through the manufacturing materials of the front lens and the rear lens, the anti-scratch and anti-wear capabilities of the rear lens and the front lens can be improved. At the same time, the anti-scratch and anti-wear coatings applied on the outer surfaces of the front lens and the rear lens can further improve the anti-wear ability of the lens. Moreover, due to the design of the protruding block, when the frame is facing down, the front lens can be kept away from the tabletop or the ground, reducing the contact between the front lens and dust particles, lowering the probability of scratching and abrasion, making the service life of the lens longer, and at the same time, the optical properties of the lens will not be changed due to wear.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: a fog-proof and scratch-proof composite coated lens, including a middle frame 1, the middle frame 1 is designed as an arc-shaped cuboid, and an annular protrusion 2 is provided inside the middle frame 1. A positioning groove 10 is provided on the outer surface of the middle frame 1, and the positioning groove 10 is located at the four corners of the middle frame 1. An inner lens 7 is fixedly installed inside the annular protrusion 2, and a bayonet slot 11 is provided on the outer surface of the inner lens 7.

[0030] When manufacturing the lens, the inner lens 7 needs to be processed and manufactured by a machine first, and then the inner lens 7 is installed inside the middle frame 1. Through the engagement of the bayonet slot 11 and the annular protrusion 2, the inner lens 7 is fixed inside the middle frame 1 to position the inner lens 7.

[0031] A heating mechanism is provided inside the inner lens 7 and the middle frame 1. The lens is heated by the heating mechanism to increase the temperature of the lens and evaporate the water vapor on the outer surface, reducing or even eliminating the fogging condition. The heating mechanism includes: a heating film 8, the heating film 8 is fixedly attached to the side surface of the inner lens 7, and the side surface of the inner lens 7 is attached to the inner surface of the middle frame 1. The inner surface of the middle frame 1 is attached to the inner surface of the heating film 8, and the heating film 8 is made of a transparent hollow material. A front lens 3 is attached to the outer surface of one end of the heating film 8 away from the bayonet slot 11, and the side surface of the front lens 3 is aligned with the side surface of the middle frame 1.

[0032] Place the heating film 8 inside the middle frame 1 and fit it snugly against the side surface of the inner lens 7. Then install and fix the front lens 3 to fix the heating film 8. When the lens is installed in the frame, the circuit in the frame can be connected to the metal contact 12. Then, by connecting the battery outside the frame to the circuit, the temperature of the heating film 8 is raised. The front lens 3 and the rear lens 5 are heated by the heating film 8, so that the water vapor on the outer surfaces of the front lens 3 and the rear lens 5 is evaporated, and the water vapor in the air is not easily condensed on the outer surfaces of the front lens 3 and the rear lens 5, keeping the front lens 3 and the rear lens 5 clean and maintaining the permeability of the lens without affecting the user's observation.

[0033] A metal contact 12 is inlaid and installed on the side surface of one end of the middle frame 1, and the metal contact 12 is connected to the input wire of the heating film 8.

[0034] Through the design of the metal contact 12, after the lens is installed inside the frame, the metal contact 12 on the side surface of the middle frame 1 can be quickly connected to the circuit inside the glasses, facilitating the installation and power-on of the lens.

[0035] A rear lens 5 is fixedly attached to the side surface of one end of the middle frame 1. The rear lens 5 has an arc-shaped design and is a sheet made of glass. A scratch-resistant and wear-resistant coating is plated on the outer surface of the rear lens 5 away from the middle frame 1. There is a filling layer 9 between the rear lens 5 and the inner lens 7, and the filling layer 9 is filled with transparent resin. A support strip 6 is provided on the outer surface of the rear lens 5, and the side surface of the support strip 6 is attached to the outer surface of the inner lens 7, and the side surface of the support strip 6 is attached to the side surface of the annular protrusion 2.

[0036] The support strip 6 and the rear lens 5 are integrally designed. When the support strip 6 is inserted into the inside of the annular protrusion 2, the middle frame 1 and the rear lens 5 can be quickly positioned, so that the rear lens 5 and the middle frame 1 can be closely attached. Then, transparent resin is injected into the filling layer 9 to make the adhesion between the rear lens 5 and the middle frame 1 more stable, improving the anti-drop and anti-impact capabilities of the lens.

[0037] A scratch-resistant and wear-resistant coating is applied to the outer surface of the front lens 3, and a protrusion block 4 is fixedly installed on the outer surface of the front lens 3. The protrusion block 4 protrudes from the outer surface of the front lens 3, and the front lens 3 is a sheet made of glass material.

[0038] The front lens 3 and the rear lens 5 are made of glass material, which can improve the scratch and abrasion resistance of the lens, making it not easy for the front lens 3 and the rear lens 5 to be scratched. At the same time, combined with the scratch and abrasion resistant coating, it can play a better protective role for the lens. And when the frame lens is facing downwards, the protruding block 4 and the front lens 3 formed by pressing and integrally molding can separate the front lens 3 from the tabletop, reducing the friction between the highest point of the front lens 3 and the particulate matter on the tabletop and the surface of objects, reducing the probability of the front lens 3 being scratched and worn, and making the service life of the lens longer.

[0039] One end of the protruding block 4 fits with the positioning groove 10, and the front lens 3 is adhered to the middle frame 1, and the annular protrusion 2 of the middle frame 1 is engaged with the bayonet groove 11.

[0040] Through the engagement of the protruding block 4 and the positioning groove 10, the front lens 3 and the middle frame 1 can be positioned, so that the middle frame 1 and the front lens 3 can be closely fitted. At the same time, when injecting adhesive between the protruding block 4 and the middle frame 1, the bonding area can be increased to make the front lens 3 and the middle frame 1 bond more closely.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
