Description

Electrochromic automatic light control skiing goggles with unlimited endurance time

Technical Field

The invention provides a technical scheme, belongs to the field of goggles, and particularly relates to electrochromic automatic light control ski goggles with infinite endurance time.

Background

The first background art. Traditional skiing goggles is equipped with three lens usually, and wherein the colorless transparency piece that shading rate is low only has the mechanics safeguard function of preventing wind sand, crashproof, uses when snowing mostly, in order to prevent strong sunshine when skiing in fine day, then need change the black lens that shading ability is strong, when standard skiing field ski night field, then need change the yellow lens of shading ability. The traditional skiing goggles have the defects that the operation of replacing the lenses is inconvenient, so that the lenses are often replaced untimely, and the optical protection effect is not in place. The embarrassing situation frequently encountered by skiers is that the tops of mountains are provided with ink lenses with strong shading capability for responding to strong sunlight with illumination of tens of thousands of Lux, the ink lenses slide to the bottoms of valleys after two minutes, enter a low-light environment with illumination of thousands of Lux, the illumination is weakened to 10% of the tops of the mountains, eyes are not suitable immediately, and even a snow road cannot be seen clearly. If the all-weather snow-sliding goggles are suitable for the environments with strong sunshine at the tops of mountains, the environments with weak light at the bottoms of valleys and the bright light environments when the standard snowfield is used for sliding at night, the dazzling pain caused by sudden changes of the luminous environment and the danger of unclear snow channels can be relieved, and the defect that the lenses are inconvenient to replace can be overcome.

The second background art. The electronic control light-changing skiing goggles which change the light transmittance of the lenses by using the 'dye liquid crystal lenses' automatically and quickly change the color without changing the lenses are used, the skiing goggles are the black lenses with strong shading capability under strong sunlight, the yellow lenses with medium shading capability under the low-light environment of the valley bottom, and the skiing goggles can also be suitable for the strong light environment of a skiing night field in a standard skiing place. This product, while originally good, has two serious drawbacks: firstly, the lens jumps between two states of 'middle shading capability' and 'strong shading capability', namely, the lens is in an ink lens state with strong shading capability when starting from a mountain top strong sunlight environment, the ambient illuminance is continuously weakened when sliding to the mountain, and when the ambient illuminance is weakened to a set value, the lens jumps from the ink lens with strong shading capability to a yellow lens with middle shading capability instantly under the control of a circuit. The sudden change not only causes the eyes to feel stabbing pain, but also has potential safety hazard; secondly, the product takes the lithium ion battery as a power supply, when the ambient temperature is lower than the lower limit of the working temperature of the lithium ion battery, the power supply capability is reduced, the lens can not be ensured to normally change color along with the intensity of illumination, and a wearer can feel happy.

The third background art. The Chinese patent 'goggles for embedded mounting of mechanical optical double protection spectacle lenses of electronic components' published shortly before application number is: CN201920192603.4 (patent for utility model), CN201910106900.7 (patent for invention). The patent forms a new space existing in a transparent lens body at the transparent window by manufacturing the transparent window at a central position inside the upper edge of the transparent lens, such as a goggle lens, so as to become a carrier (hereinafter referred to as 'carrier'); TN type liquid crystal glasses (hereinafter referred to as 'liquid crystal glasses') with polarizers on two outer surfaces are used as an executive component for changing the light transmittance, and transparent adhesive is attached to the light emergent surface of the carrier; a strip-shaped decorative sheet with a certain thickness and a rectangular through hole is arranged on the incident light surface of the carrier, and a space formed by superposing a three-dimensional space formed by the rectangular through hole and a three-dimensional space of a through window of the carrier accommodates the miniaturized electronic components. The cylindrical convergent lens, the solar cell module and the control circuit module jointly form a miniaturized full-function electronic component (hereinafter referred to as 'electronic component'), and the electronic component is embedded into a space formed by the decorative sheet through hole and the transparent window of the carrier; electrically connecting the output end of the electronic component with a specially-made fold-back copper foil electrode on the liquid crystal glasses; the gap between the periphery of the electronic component on the incident light surface and the transparent window is shielded by the decorative frame; after embedding the liquid crystal spectacle lens electrode and the electronic component into a space formed by a through window of a carrier and a decoration frame, filling an irregular cavity left by using an insulating silicone grease paste; the light exit surface of the transmission window and the electrodes of the liquid crystal spectacle lens are shielded by the decorative sheet, which constitutes the basic form of the present invention, namely, the 'embedded type mechanical optical double-protection spectacle lens for mounting electronic parts'.

If the technique can be used directly to make ski goggles, the different disadvantages of the first and second background techniques, respectively, can be overcome. The skiing goggles and the third related art have similar appearances and similar requirements on functions, which is a matter of simple and rational affairs, however, analysis proves that the skiing goggles are not feasible, what reason? This is to be said from the specification of ski goggles.

Although the skiing goggles have no national standard (foreign) in China, the skiing goggles are used as mature commodities of sports equipment in the market, and the public has a lot of consensus on technical indexes of the skiing goggles, including the fact that the skiing goggles are light and have a large visual field. Both requirements are clearly justified and are also met by design considerations. The lens area must be enlarged in order to enlarge the field of vision, and after enlargement of the lens area, the inevitable consequence is increased weight, which contradicts the light-weight demand.

To balance the tradeoff between extended vision and portability, the only exit is to reduce the thickness dimension of the lens. The mechanical protection performance of the lucky skiing goggles can be slightly wider than that of a goggle lens which is used for dealing with shrapnel and flyrock on a battlefield, and the problem seems to be solved. The matter is not so simple:

in the third background art, as described above, "a transparent window is formed from a transparent lens, such as a goggle lens, at a central position inside the upper edge thereof, and a new space is formed in the transparent lens, and the window is used as a three-dimensional space for accommodating electronic components, and the three-dimensional space is reduced due to the reduction in thickness of the lens in the goggle, so that there is no place to accommodate a pulse oscillator module corresponding to the control circuit module in the third background art.

In summary, it can be determined that the background art can not be applied to eliminate the dazzling pain of the skiers and can not satisfy the requirements of portability and large visual field. The electrochromic automatic light-control skiing goggles with unlimited endurance time also become the practical requirement of the skiing public.

Disclosure of Invention

The invention aims to provide a pair of skiing goggles which has better optical protection function than the first background technology and the second background technology, has a visual field larger than the third background technology, is lighter than the third background technology, and completely overcomes the defect that the endurance time of the second background technology is not guaranteed.

The invention aims to realize electrochromic automatic control smooth snow goggles with infinite endurance time, which are formed by connecting parts such as a TAC (TAC) sheet, a TN (twisted nematic) type liquid crystal lens, an ornament frame, a solar cell module, a pulse oscillator module, an input end connecting wire, an output end connecting wire, a mirror frame with a groove, a double-sided foam rubber part, a multi-interface adapter and the like according to a specified relation. The specific structure and its improvement are described below.

The TAC sheet is a specially-shaped contour line cylindrical sheet-shaped piece made of an optical-grade cellulose triacetate plate (TAC) with the thickness of 0.8mm to 2.0mm, and comparison shows that the rainbow interference phenomenon of transmitted light can be effectively inhibited by matching the optical-grade TAC plate with the TN type liquid crystal lens.

Besides mechanical protection, the TAC sheet also needs to support TN liquid crystal lenses, decorative frames and solar cell modules.

A rectangular through window with large transverse size and small vertical size is formed in the inner middle position of the TAC sheet, and has two functions, namely one function is used as a wire passing hole for connecting input ends, and the other function is used as a space for accommodating a rectangular frame of the escutcheon.

The TN type liquid crystal lens is similar to a TAC sheet in shape and smaller than the TAC sheet in size, and is attached to the B surface of the TAC sheet through a transparent film (namely, in the goggle product industry, an incident light surface is generally called as the A surface, an emergent light surface is called as the B surface, and the same is applied below). The contour line of the TAC lens is approximately parallel to the contour line of the TAC lens to form the composite lens. The TN type liquid crystal lens used for the skiing goggles is required to prevent strong sunlight on the sky and strong snow on the ground, so that the vertical visual angle is required to be enlarged in design compared with the traditional electrically-controlled color-changing liquid crystal goggles.

The manufactured composite lens not only serves as an installation means of the TN type liquid crystal lens, but also has various functions: the superposition of the two can enhance the mechanical protection capability to the eyes of the wearer; after the TN type liquid crystal lens is attached to the B surface of the TAC sheet, the mechanical protection of the TAC sheet can be obtained; and because the TAC sheet has the functions of heat insulation and heat preservation, the TN type liquid crystal lens is separated from the open air and cold air, and simultaneously obtains the radiant heat of the face of a wearer, so that the temperature of the liquid crystal layer is ensured to be maintained above minus 30 ℃, the liquid crystal layer is always kept within the range of normal working temperature from minus 30 ℃ to plus 40 ℃, and the defect of failure at low temperature is avoided.

The irregular annular surface between two approximate parallel lines which are formed by the contour line of the TN type liquid crystal lens and the contour line of the TAC sheet is used for being attached to the surface of the double-sided foam rubber piece A, the distance b between the two approximate parallel lines is 4mm to 7mm, the bonding force of the attaching is lost when the distance is too small, and the visual field of the lens is lost when the distance is too large.

Two electrode plates led out of the TN type liquid crystal lens by fpc (English abbreviation of flexible printed circuit board, the same below) are extended from the central position of the upper side of the TN type liquid crystal lens in parallel along the plain line direction of the cylindrical surface of the liquid crystal lens.

The decorative frame is an injection molding piece with a special-shaped contour line and a rectangular window, and the left end and the right end of the rectangular window are respectively provided with a step receding from the surface A to the surface B and used for limiting the position in the depth direction when the solar cell module is mounted. Four sides of the rectangular window of the decorative frame extend to the surface B to form a rectangular frame, and the function of the rectangular frame is to prevent the waterproof filler in the rectangular window from overflowing to cause the damage of the appearance of the lens. The decoration frame is arranged on the surface A of the TAC sheet, and the rectangular frame is placed in the rectangular through window of the TAC sheet during installation.

The solar cell module is a power supply and photoelectric sensor of the project, a plurality of solar cell chips are attached to a PCB (printed circuit board, lower part of the PCB) and are connected in series by inner leads, and when the solar cell chips are monocrystalline silicon solar cell chips or polycrystalline silicon solar cell chips, the area of each chip is 8mm²To 12mm²The number of the small pieces connected in series is 5 to 7; or when a gallium arsenide + germanium material multilayer heterogeneous PN junction solar cell is adopted, the area of a single chip is 12mm²To 24mm²The number of small pieces required is 1 to 2.

The adoption of a solar cell module as a power supply is a key measure for achieving infinite endurance time. The unlimited endurance time is an important technical index of the project, namely the commitment: the skiing goggles made according to the technical scheme can be used at any time in any skiing field from the perspective of a power supply, and as long as the front sunlight intensity or the snow light intensity reaches the starting illumination specified by the sensitivity index of the skiing goggles, the color of the lens begins to deepen, the eyes of a wearer cannot be stimulated by strong sunlight or strong snow light, the power supply deficiency caused by low temperature cannot be caused, and the defect that the light control function of the liquid crystal lens is weakened is induced.

The starting illumination value specified by the sensitivity index is E less than or equal to 5000Lux, which is 4.2% of the maximum value 120000Lux of the ground sunlight illumination. Considering that the initial light transmittance of the composite lens is 34%, when the sunlight intensity is 5000Lux, the illumination intensity of the lens is only 1700Lux, and the composite lens is not strong in the open air. The wearer's eyes are initially protected optically before the liquid crystal lenses discolor.

The electrochromic automatic light control skiing goggles with unlimited endurance time manufactured according to the technical scheme have the transmittance of incident sunlight below and obliquely above strong sunlight of less than or equal to 5 percent, and the value is lower than that of common sunglasses, thereby meeting the standards of special-purpose sunglasses (skiing, mountain climbing, beach and the like) in QB2457-1999 sunglasses.

The solar cell module is used as a photoelectric sensor, is a medium for butting the intensity of ambient light with the incident light intensity of binocular pupils of a wearer, is a controller for amplitude modulation of pulse waveforms of the oscillator, is a key component for determining the intensity of signals at the output end of the pulse oscillator and the color changing depth of the TN type liquid crystal lens, is continuous and soft in light control, and can avoid the bad phenomenon of jumping between light and shade.

The pulse oscillator module is an integrated component formed by encapsulating functional components including chip components such as ICs (integrated circuits) and the like which generate pulse signals in a metal box by using epoxy glue and exposing 2 input end connecting terminals and 2 output end connecting terminals.

The metal box can be made of stainless steel, copper alloy, titanium alloy, aluminum alloy and the like.

The input end connecting wire is two wires which electrically connect the electrode of the solar cell with the input end of the pulse oscillator module.

The output end connecting wire is two wires which electrically connect the TN type liquid crystal lens electrode with the output end of the pulse oscillator module.

The mirror frame with the groove is characterized in that a rectangular groove is formed in the middle of the upper section of the A surface of the frame body of the traditional ski goggles, and a three-dimensional space formed by the rectangular groove and the middle of the upper section of the B surface of the multi-interface adapter is used for accommodating a pulse oscillator module; a plurality of mortise holes are provided on the a-side thereof for connection with a multi-port adapter described later.

The double-sided foam rubber piece is formed by cutting a commercially common double-sided foam rubber sheet, and the overlapped section of the middle section of the double-sided foam rubber piece and the rectangular through window of the TAC sheet is removed, so that a passage is reserved for an input end connecting line and an output end connecting line.

The B-side of the double-sided foam piece is attached to the a-side of the multi-port adapter.

The multi-interface adapter is an injection molding special-shaped ring piece, and the multi-interface adapter takes the following 9 tasks:

the surface A is connected with the annular surface of the surface B of the TAC sheet through a double-sided foam rubber piece.

And 2, in order to protect the outer ring edge of the double-sided foam rubber piece, a convex ring extending to the surface A is arranged along the outer edge of the double-sided foam rubber piece.

And 3, arranging a narrow brim extending to the A surface direction at the central position of the convex ring to shield a gap left by removing the middle section on the double-sided foam rubber piece.

And 4, in order to prevent the thickness of the TN type liquid crystal lens from exceeding the thickness of the double-sided foam rubber piece and preventing the multi-interface fitting piece from being tightly attached to the annular surface of the TAC sheet, a step which is concave towards the surface B is formed on the surface A along the inner opening, so that the thickness dimension of the TN type liquid crystal lens is set aside.

And 5, a rectangular groove is arranged in the middle of the upper section of the B surface of the mirror frame, the position of the rectangular groove corresponds to the rectangular groove on the A surface of the mirror frame with the groove, and a three-dimensional space formed by the two butted rectangular grooves is used for accommodating the pulse oscillator module.

And 6, the bottom of the B-surface rectangular groove is provided with three wire passing holes, the three wire passing holes are distributed at the left end and the right end and are respectively used for two input end connecting wires to pass through, the middle one is used for two output end connecting wires to pass through, the three wire passing holes are all rectangular, and the hole height is equal to the height of the rectangular groove.

And 7, two bridge-shaped structures are formed among the three rectangular wire passing holes, the bridge-shaped structures are also useful and are adjacent to fpc electrodes of the TN type liquid crystal lens, the upper half sections of the A surfaces of the two bridge-shaped structures are respectively provided with a step protruding towards the A surface, and the bridge-shaped structures are just used as supporting platforms when connecting wires of output ends of flexible printed circuit boards fpc of the TN type liquid crystal lens are soldered, so that the force is facilitated, the phenomenon that conductive adhesive between fpc and an ITO film of a liquid crystal box is separated due to deformation stress when fpc on the TN type liquid crystal lens is bent in an overlarge bending range during soldering is prevented.

And 8, the surface B of the bridge-shaped structure does not need to be provided with a raised step, and the pulse oscillator module has a positioning function when being installed.

And 9, arranging a plurality of tenons on the surface B of the multi-interface adapter, and inserting the tenons into corresponding mortise holes arranged on the surface A of the frame with the groove.

Compared with the background technology, the optical protection function of the invention is superior to the first background technology and the second background technology, thus ensuring that the eyes of a wearer cannot be stimulated by strong sunlight and strong snow light; the visual field is larger than that of the third background technology, and is lighter than that of simply borrowing the third background technology; thoroughly overcoming the defects of the second background technology that the endurance time is not ensured and the light shielding capability of the lens is jumped; the contradiction in various aspects such as functional indexes, structural design, process method and the like is coordinated, and comprehensive improvement is obtained.
