New description: [New technical field] This creation is related to safety helmet goggles, especially the safety helmet with double-layer lens structure, shading, UV blocking, noise and temperature protection.目^八 [Prior Art] The main function of the helmet is to protect the head of the hoist, to prevent the head from being injured when it is struck by external force. Some of the safety napkins in the past are covered by the body cap. In addition to the _ eyepiece 'safety-based requirements' goggles material - generally made of polycarbonate (Polycarbonate, PC), polycarbonate is a material that is more impact resistant than polymer resin, and then on the surface Wear-resistant treatment, very suitable for making helmet goggles. The traditional safety helmet goggles are colorless transparent lenses, which do not have the function of shading or blocking ultraviolet rays. In order to achieve the purpose of shading or blocking ultraviolet rays, there are dark or dark helmet goggles and anti-reverse correction. Safety helmet goggles were developed to ask the market. Depending on the technology used, it can be divided into three types. The first one is "color lens", which mainly infiltrates φ - some chemicals into the material, so that the lens has color and can absorb light of a specific wavelength; It is a "coated mirror; i"' is mainly coated with a special material on the surface of the lens. The film is used to reflect the external light from the film. The part of the light depends on the H type, which is a "color changing lens". In the lens material, special substances such as gasified silver or silver halide are uniformly distributed in the lens of the lens. In general, the visible light without the line can penetrate these molecules. Transparent and colorless, but when exposed to the ultraviolet light of sunlight, 'these molecules will undergo chemical changes, so that their crystallographical new structure will absorb some ultraviolet rays, which will make the color lens darker or deeper. Color, and achieve the purpose of 3 M435847 sunshade and ultraviolet light, and the degree of darkening or darkening of the color changing lens depends on the intensity of the ultraviolet light. Under artificial light containing no ultraviolet light, photochromic lenses will gradually change with time elapsed back transparent and colorless state. Based on the safety considerations of driving, when used in an outdoor sunlight environment, the safety helmet goggles have a scale and a barrier material, but after a human night or when it encounters a cloudy or awkward situation, The helmet goggles, which will reduce the light intensity, should be used as well; therefore, if the helmet goggles made using the aforementioned "color lens" and the second "ship lens" are used, it is obviously the same problem. Using the third type of "color changing lens" directly to make the safety helmet goggles, although it has the function of automatically adjusting the brightness and darkness, it can be applied to indoor/outdoor and day/night, but the "color changing lens" is more expensive and the structural strength is higher. The transparent and colorless safety towel f is weakened, so it is not suitable to use the "color changing mirror>" to make the safety helmet goggles. [New content] Based on the problem of traditional safety helmet goggles and the need to block or block UV rays, this creation proposes a safety helmet goggles that have the effect of shading, blocking UV's isolation noise and temperature. In order to achieve the above-mentioned effects, an embodiment of the creation of the safety helmet goggles comprises: an outer lens which is a transparent colorless lens, an outer lens having at least one mounting means for attaching the outer lens to the safety helmet; and an inner lens. In the case of a color-changing lens, the inner lens is fixed on the side of the outer lens near the inside of the helmet, and there is a gap between the inner lens and the outer lens, and the inner lens can be darkened after being exposed to ultraviolet rays. M435847 According to another embodiment of the present invention, there is a bond between the outer lens and the inner lens, and the adhesive is distributed along the edge contour of the inner lens of the inner layer, and the adhesive has deformable and soft characteristics for the outer lens and The inner lens is bonded to form a double-layer lens structure, and the stress between the outer lens and the inner lens can be buffered during the thermal expansion and contraction of the outer lens and the inner lens to avoid cracking. From the above description, we can understand that the creation of the safety helmet goggles uses the double-layer lens structure of the inner layer lens and the outer layer lens, and the color-changing lens with weak structural strength is used as the inner layer lens, 9 has the effect of blocking ultraviolet rays and shading. It also has the effect of isolating noise and temperature. The embodiments of the present invention, as well as its advantages and effects, will be described below in conjunction with the drawings. [Embodiment] First, please refer to "FIG. 1", which discloses an embodiment of the creation of the safety helmet goggles, comprising: an outer lens 20, which is a transparent colorless lens, and the outer lens 20 has at least one The mounting means can mount the outer lens 20 to the helmet 40 (see "Fig. 5"); and the φ inner lens 30' is a color changing lens, and the inner lens 30 is fixed to the side of the outer lens near the inside of the helmet (see " Figure 2)), the fixed way can be glued or snapped, there is a gap between the inner lens and the outer lens, and the inner lens can be darkened after being exposed to ultraviolet light. The inner layer lens 30 is a color-changing lens made of a light-transmitting material which is infiltrated with a special substance such as silver sulfate or silver halide. The infiltrated substance molecules are evenly distributed in the lens. Under normal circumstances, the visible light containing no ultraviolet light can be Through these molecules, the color-changing lens remains transparent and colorless, but when exposed to the ultraviolet light of sunlight, these molecules undergo chemical changes that cause the crystal shape of the 5 M435847 to change, and the new molecular structure absorbs some of the ultraviolet rays. In turn, the color-changing lens is darkened or turned into a dark color to achieve the purpose of shading and blocking ultraviolet rays, and the degree of darkening or darkening of the color-changing lens depends on the intensity of the ultraviolet light, and once returned to the room, it does not contain Under the artificial light source of ultraviolet light, the color changing mirror will gradually change back to a transparent and colorless state with the passage of time. The outer layer lens 20 is in principle a transparent lens, the shape of which depends on the type and shape of the mounted safety helmet 4,. One implementation of the mounting means is to mount the outer layer lens 2 to the safety helmet 40 by means of bolts 5 (see "Fig. 5", one of the embodiments is constructed such that the end portions of the outer lens 2 are provided with perforations 22, and at the corresponding positions of the main body of the hard hat 40, screw holes 41' are utilized. The bolt 50 is passed through the through hole 22 of the outer lens 20 and then screwed to the screw hole 41 of the main body cap, so that the safety helmet goggle 1 can be attached to the main body cap of the safety helmet 4〇. An embodiment of the outer layer lens 20 is constructed as shown in FIG. 4, and the outer layer lens 2 has a viewing area a protruding toward the front of the helmet* at a position where the inner layer lens 30 is intended to be mounted. The rear side (that is, one side of the outer lens 20 near the inside of the helmet 4) forms a boot that is recessed toward the front of the helmet (9), and (10) the contour of the lens 3G can be placed just behind the viewing area A. (See "Fig. 2"), and there is a gap between the inner lens 3 〇 and the outer lens 20, so the double lens structure has the effect of isolating noise and temperature. According to another embodiment of the present invention, there is a glue 60 between the outer lens 2 and the inner lens 3 (as shown in "Fig. 3"), and the adhesive 6G is distributed along the edge of the inner lens of the inner lens. (As shown in Figure 4), the adhesive 60 has the characteristics of being deformable and soft, and the adhesive 6 〇 can be made of foam double-sided tape, _ or a sponge pad with glue on both sides or One of the analogs is used to bond the outer layer lens 20 and the inner layer lens 3 into a double-layer lens structure, and can also be used in the external 20 and 峨>; 3Q in the thermal expansion and contraction of the excess, buffering the outer lens 6 M435847 20 and the inner lens 3 应力 stress between each other to avoid cracking.
