Description

The structure of the helmet color changing lens

The present invention provides a structure of color-changing lenses for safety helmets, in particular to a structure of color-changing lenses for safety helmets that has good fitting effect and has the function of automatic thermal repair of damage.

Press, the helmet includes a cap for protecting the rider's head, and a lens installed on the front side of the cap to block wind and rain, and the general lens has a good light transmittance, so that the user can see clearly For the scenery outside the lens, in order to avoid the problem of glare caused by direct sunlight, ink-colored lenses can be selected. However, such dark-colored filter lenses may cause poor vision at night. Therefore, helmet lenses are combined with The technology that combines the color-changing lens of the glasses is introduced.

The color-changing technology of the color-changing lens is divided into electrochromic and photochromic. Both of them can change color after absorbing ultraviolet light and form a lens that can block sunlight. After not irradiated with sunlight, it returns to the original light transmittance again. Become clear. However, regardless of electrochromic or photochromic technology, the color-changing material covers the surface of the lens with a color-changing film. The method is usually by sputtering, spraying or immersion. However, once this method causes the lens to be damaged When scratched or worn, the discoloration film on the surface will begin to peel off, so that the worn part loses the effect of discoloration. Moreover, the manufacturing cost of the color changing lens is significantly higher than that of the ordinary lens, and once worn, it can only be replaced. If the color changing effect is to be ensured, the high replacement rate of consumables will cause a burden on the user.

In addition, the color-changing film is usually set on the outer surface of the lens, so it is prone to scratching and abrasion. However, if it is set on the inner surface of the lens, although the factors of wind and sand abrasion can be reduced, it will affect the speed of heat transfer due to the thickness of the lens. , Thereby delaying the speed of discoloration of the discolored thin surface, which will affect the convenience of use.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicants of this new model and related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of the present model has collected relevant information, evaluated and considered by multiple parties, and has accumulated years of experience in this industry, through continuous trials and revisions, to design such a good fit. And has a new patent for the structure of the helmet color-changing lens with automatic thermal repair function.

The main purpose of the present invention is to provide a safety helmet color-changing lens with a color-changing function, and use the design of a soft base material layer to achieve the purpose of smoothly attaching to the lens and using the heat-repairing layer to automatically heat-repair the damage.

To achieve the above purpose, the main structure of the present invention includes: a helmet lens, an adhesive layer, a soft substrate layer, a thermal repair layer, a polyurethane layer, a silicone layer, and a plurality of color-changing raw materials, wherein the The adhesive layer is arranged on the outer side of the helmet lens, the flexible substrate layer is correspondingly attached to the adhesive layer, and its material is selected from polyurethane (PU), thermoplastic polyurethane (TPU), polyvinyl chloride (Polyvinyl Chloride). , PVC), or polyethylene terephthalate (Polyethylene terephthalate, PET), the thermal repair layer is provided on the soft substrate layer, the polyurethane layer is provided in the thermal repair layer, the silicone The alkane layer is arranged on one side of the polyurethane layer, and the color-changing raw material part is correspondingly combined with the soft base material layer or the thermal repair layer.

In addition to the function of changing the color of the raw material, the helmet lens can absorb ultraviolet rays and automatically adjust the shading rate. Since the soft base layer is made of highly elastic material, it can be combined with the adhesive layer for multi-directional curved surface stretching and bonding. It can be used with hot air steam to heat the material to soften and shrink, which can eliminate the extrusion stress caused by the large curved surface. The thermal repair layer composed of polyurethane layer and silicone layer can use high temperature when scratched or worn. Automatically repair, and eliminate the problem of the failure of the discolored materials caused by the wear of the helmet lens, thereby reducing the helmet lens replacement rate and improving the durability of the helmet lens.

With the above-mentioned technology, it is possible to overcome the problems of poor adhesion of the color-changing film, high lens replacement rate, and inability to automatically repair damage existing in the conventional safety helmet color-changing lens, and achieve the practical progress of the above-mentioned advantages.
