Description

Mirror bonding type functional diaphragm structure

This creation is about a mirror-fitted functional diaphragm structure, especially a functional diaphragm structure design that can be directly and fully attached to the helmet mirror or sports and industrial goggles.

Press, as shown in the first figure, take the lens used in a safety helmet as an example. The front edge of the helmet body is mainly provided with a flip-out lens 10, which is made of transparent or translucent material. 10 contains a front side 11 and an opposite back side 12, which can be used to cover the face or the front of the eyes with the movable assembly of the sides and the cap body as the axis of action, or when not in use Open it up to the top of the helmet body.

Basically, if the lens of this type of helmet is not processed with a special protective layer, the protection against long-term strong sunlight is quite weak. Due to the harm to the human body caused by over-exposure of ultraviolet rays, various research institutions have proven that most riders wearing helmets must be exposed to the sun for a long time, and the protection of the eyes cannot be ignored.

In the existing known techniques, this type of lens can be formed into various protective structures due to different mirror processing technologies and methods, including coating a photochromic layer on the mirror processing, through The photochromic layer can adjust the light transmittance of sunlight to achieve protection. Another way is to process and coat the polarizing layer material to prevent glare. Of course, other methods include processing an anti-reflective layer that eliminates light reflection, and an anti-fog layer that adheres to water and gas.

However, no matter what kind of protective structure is adopted for this kind of lens, the lens itself must be processed in the factory before leaving the factory. Taking the photochromic coating on the mirror surface as an example, more expensive equipment must be used for processing, and of course the cost and price of this type of lens will be greatly increased. The most important thing is that unless the existing helmet lenses that have been installed on the cap body are discarded, and then replaced with new lenses with a processed protective layer or protective layer at a higher cost, it will be difficult to achieve the required protective function. .

The main purpose of this creation is to provide a mirror-fitted functional diaphragm structure, which can directly bond the functional diaphragm to the mirror surface while retaining the existing lenses to achieve the required various protections or structural enhancements. Class functional requirements.

A further purpose of this creation is to provide a mirror-laminated functional membrane structure that can meet the needs of users to provide single-layer or multi-layer laminated functional membranes for protection or structural strengthening.

Another purpose of this creation is to provide a mirror-fitted functional membrane structure, which can be optionally attached to the front or opposite back of the lens.

To achieve the above-mentioned purpose, the mirror-laminated functional film structure of this creation includes a functional film that can be attached to the surface of a lens. The functional film includes a functional film layer, and the functional film layer is an adjustment Light transmittance photochromic film layer, a glare prevention At least one of a polarizing film layer, a brightening film layer, an anti-fog film layer, or a strengthening film layer is formed; one side of the functional film layer is provided with an adhesive layer, and the adhesive layer is provided with a layer before use The release layer makes the release layer cover the surface of the glue layer.

The aforementioned mirror-laminated functional film structure, wherein the functional film layer is a photochromic film layer for adjusting light transmittance, a polarizing film layer for preventing glare, a brightening film layer, and an anti-fogging film A layer or a reinforced film layer is formed by stacking two of the film layers.

The aforementioned mirror-laminated functional film structure, wherein the functional film layer is a photochromic film layer for adjusting light transmittance, a polarizing film layer for preventing glare, a brightening film layer, and an anti-fogging film A layer or a reinforced film layer is formed by stacking more than three (including) film layers.

In the aforementioned mirror-bonded functional film structure, the surface of the lens includes a front surface and an opposite back surface, and the functional film is bonded to the front surface of the lens with an adhesive layer.

In the aforementioned mirror-bonded functional film structure, the surface of the lens includes a front surface and an opposite back surface, and the functional film is bonded to the back surface of the lens with an adhesive layer.

In the above-mentioned mirror-bonded functional film structure, the other side of the functional film layer away from the glue layer is further provided with a water-repellent layer.

In the aforementioned mirror-bonded functional film structure, a bacteriostatic layer is further provided on the other side of the functional film layer away from the glue layer.
