Background of invention

The present invention relates to the application of electronics in safety goggles, more particularly, relate to a kind of new construction that conducts electricity the safety goggles framework.

Now multiple different electronic application is arranged in safety goggles, their existing amusement effects also have utility function.For example at No.4, it is neighbouring to create a kind of recreational visual effect that the light emitting diode that glistens in 254,451 United States Patent (USP)s (LED) is placed on the safety goggles front baffle.What is more important, electronics practicality are used example and are comprised the electro-optical device that is used for safety goggles, such as in order to control by safety goggles eyeglass penetrability the electrochromism demonstration and the liquid nematic crystal (respectively as No.5,455,637 and 5,276,539 United States Patent (USP)s), prevent that heat generating resistor that eyeglass hazes is (as No.5, and can change lens optical character and influence device 459,533 United States Patent (USP)s), (as No.5 by the eyeglass video, 229,885 United States Patent (USP)s).Other electronics practical application in the safety goggles framework comprises that also hearing device is (as by No.3, the visible osophone of 853,393 United States Patent (USP)s), and with image projection can see (as No.5 so that wear the people of safety goggles at the dorsal part of eyeglass, 463,428 United States Patent (USP)s).

Only manage the work of this technology and carried out decades, but still need a kind of safety goggles conductive frame that can be successfully shape and function be combined.Because size is limited, and the safety goggles wearer requires light and handy, compact system, thereby the position of power supply, logic and switch control and pass the electrical connection of safety goggles framework and the circuit of selected these and other parts has proposed great challenge to design.And Electronic Design must be suitable for the variation (being very big variation sometimes) of popular safety goggles style in every year.

Summary of the invention

The present invention has successfully solved above-mentioned design challenge by proposing a kind of Goggles frame shelf structure, and this structure has been set up the circuit by the safety goggles framework, and it is easy to adapt to electronic application and the potential infinite variation of safety goggles style.More particularly, the present invention includes a plurality of conducting channels mutually insulated, coaxial placement, it provides the basic framework of conduction for building final safety goggles finished product.Like this, set up a conducting channel that can be used for whole safety goggles framework, this circuit has a very little total diameter at the arbitrary set point along the safety goggles framework.

Before this, the conducting channel in the safety goggles requires that heavy framework is arranged, because electrical lead and safety goggles framework are to regard independently parts as, must manage they are combined.This causes the diameter and the width of the front baffle of electronics eyewear apparatus in the prior art and safety goggles support all very big usually.And the present invention is provided with independently circuit with coaxial manner; its SMIS or central circuit preferably include the base metal or the core of common safety goggles framework; thereby provide a kind of safety goggles conductive frame; its overall dimension is minimum, so just selects to have stayed enough spaces for various finished product goggle designs on this basic framework.

In a preferred embodiment, the base metal core for example is made of NiAg, and is positioned at the safety goggles cantilever tip or other requires locational power supply that positive charge is provided by being connected to.If desired, can apply additional conductive layer to base metal, for example, but NiAg base metal core re-plating skim gold.One deck insulating coating can be applied on the base metal core such as the non-conductive layer of applying electrophoretic coating (" E-coating "), silicon, quartz or aluminium nitride, subsequently coating one deck outer conducting layer (as ZrNi, Al or TiNi) on insulation course again.Insulation course can for example be used dipping, baking or a kind of charged particle technology and be applied.Outer conducting layer provides negative charge by being connected to power supply.

Can select different deposition processs for mending metallic coating, such as EVAD (evaporation), PVD (physical vapor deposition), CVD (chemical vapor deposition) and sputter cladding process.The terminal of electron device connects and can or be obtained by on selected position framework covering between depositional stage, perhaps obtains by removal material (as by wiping) after deposition.Best, if required, framework can be encapsulated in the outer protection sheath layer.
