The technical field of the safety helmet worn in life and work, especially the structure of the safety helmet worn when riding a bicycle or locomotive (motorcycle).

Background technique

With the rise of oil prices around the world and the awareness of environmental protection and energy saving, bicycles and motorcycles are widely used by urban office workers as a means of transportation to replace cars, and bicycles and motorcycles are popular in China's traffic development due to their cheap price and convenient parking. History has always played a pivotal role, but unlike cars, bicycles or motorcycles have a variety of safety equipment such as hard car shells, airbags, bumpers, anti-deadlock braking systems, and anti-skid control systems. The degree of danger on the road and the death rate of traffic accidents are far greater than those of cars. Therefore, the government implemented a policy of mandating motorcycles to wear safety helmets in June 1997, hoping to make the drivers and passengers who ride motorcycles mandatory Wearing a helmet can reduce accident injuries caused by traffic accidents, thereby reducing the impact of accident injuries on individuals and families or the increased medical costs and social costs caused by accident injuries. Therefore, helmets are very important for cycling. Cyclists or motorcyclists on the road are very important, which can effectively protect the life safety of riders and reduce accidental death rates, and because bicycles rarely have lighting devices such as headlights, fog lights, direction lights, and kill lights, so riding a bicycle in When on the road at night, it is not easy to be detected by the surrounding vehicles, and it is easy to be hit by the surrounding vehicles, which will cause traffic accidents. Therefore, some users have installed reflective layers on the helmets, but the helmets used The structure of the reflective layer is shown in Figure 4 and Figure 5. The reflective material A on the safety helmet B has a base material A1, and the outer surface of the base material A1 is provided with a silver paste layer A2 combined with a plurality of glass beads A3. When the type of reflective material A is pasted on the outer surface of the helmet B through thermoplastic processing, the silver paste layer A2 combined with a plurality of glass beads A3 will encounter a position with a large bending angle, because the silver paste layer A2 cannot resemble the base Material A1 is also malleable, and can be tightly adhered to the outer surface of the helmet B, causing fine cracks in the silver paste layer A2 on the base material A1, and causing the multiple glass beads A3 combined with the silver paste layer A2 to fall off. , and seriously affect the reflective effect of the reflector A on the helmet B, so that the surrounding vehicles cannot clearly see the driver, and are easily hit by other vehicles.

How to solve the problems and deficiencies of the reflective layer structure of conventional helmets is the direction of research and improvement for relevant manufacturers engaged in this industry.

Detailed ways

In order to achieve the above-mentioned purpose and effect, the technical means and the structure adopted by the present invention are hereby drawn to illustrate in detail the features and functions of the preferred embodiments of the present invention as follows.

Please refer to Fig. 1, Fig. 2 and shown in Fig. 3, which are schematic structural views, three-dimensional appearance diagrams, and structural sectional views of preferred embodiments of the present invention. It can be clearly seen from the figure that the reflective layer structure of the safety helmet of the present invention It is composed of a reflective object 1 and a cap body 2, wherein:

The reflective object 1 is a substrate 11 made of materials such as polyethylene terephthalate (PET), polyvinyl chloride (PVC), plastic film, etc., and the outer surface of the substrate 11 is provided with a first fluorescent layer 12, and The first fluorescent layer 12 is made by mixing hot melt adhesive into silver paste, and the second fluorescent layer 13 is arranged on the first fluorescent layer 12, and the second fluorescent layer 13 is made of silver paste material, and the second fluorescent A plurality of glass beads 131 are bonded to the layer 13 .

The outer surface of the cap body 2 is formed with a reflective object 1 by processing.

When the above-mentioned reflective material 1 is processed and combined, a hot-melt adhesive is hot-press formed on the substrate 11 having a polyethylene terephthalate (PET) film material, and silver paste is mixed in the hot-melt adhesive molding process, and Forming the first fluorescent layer 12, so that the first fluorescent layer 12 has both the better ductility of the hot melt adhesive and the reflective properties of the silver paste, and the second fluorescent layer made of silver paste is hot-pressed on the first fluorescent layer 12 13, and a plurality of glass beads 131 are implanted on the silver paste material of the second fluorescent layer 13 by hot pressing, so that the second fluorescent layer 13 has a good reflective effect.

In addition, during the combination of the cap body 2 (such as bicycle helmets, motorcycle helmets, and construction site helmets) with the reflective object 1, the formed reflective object 1 is processed by a processing method (such as thermoplastic, adhesive or hot pressing). etc.) formed on the outer surface of the cap body 2, when the reflective object 1 encounters a larger bending angle on the outer surface of the cap body 2 or the position of the edge of the ventilation hole, due to the hot melt adhesive composition contained in the first fluorescent layer 12, The first fluorescent layer 12 has better ductility, and can extend along the second fluorescent layer 13 through the first fluorescent layer 12, so that the second fluorescent layer 13 can be closely adhered to the surface of the first fluorescent layer 12 In addition, it is not easy for the second fluorescent layer 13 to produce fine cracks, and it can prevent the plurality of glass beads 131 from falling off from the cracks in the second fluorescent layer 13, and then reach the reflective objects set on the outer surface of the cap body 2. 1 has a good reflective effect.
