Description

Technical Field

[0001] This application relates to the field of electrochromic technology, and more particularly to an electrochromic glasses. Background Technology

[0002] Electrochromic glasses are smart glasses that can adjust the color of the lenses according to the intensity of external light. They work by using electrochromic materials that undergo reversible color changes under the influence of an electric field. When the external light changes, the control system in the glasses adjusts the voltage applied to the electrochromic layer of the lens based on instructions or sensor data, thereby altering the lens's light transmittance.

[0003] In actual use, especially in scenarios with large changes in ambient temperature, such as moving from a cold outdoor environment to a warm indoor environment, or from an air-conditioned environment to a hot outdoor environment, the surface of electrochromic glasses is prone to water vapor condensation due to temperature differences, forming a fog layer that seriously affects the user's vision.

The lens frame has a hollow cavity with a first opening and a second opening communicating with the outside. The lens is connected to the lens frame and sealed within the first opening of the hollow cavity. The anti-fog film is connected to the lens frame and sealed within the second opening of the hollow cavity. The hollow cavity separates the lens and the anti-fog film, resulting in a greater distance between them. This reduces the heat conduction rate between the lens and the anti-fog film, thus minimizing the temperature difference between the inner and outer sides of the anti-fog film and enhancing its anti-fogging effect.

[0034] Electrochromic glasses are smart glasses that can adjust the color of the lenses according to the intensity of external light. They work by using electrochromic materials that undergo reversible color changes under the influence of an electric field. When the external light changes, the control system in the glasses adjusts the voltage applied to the electrochromic layer of the lens based on instructions or sensor data, thereby altering the lens's light transmittance.

[0035] like Figure 1 As shown, the electrochromic glasses 100 includes a lens frame 110, a lens 120, an anti-fog film 130, and an electrochromic element 160. The lens frame 110 has a hollow cavity 115, which has a first opening 113 and a second opening 114 communicating with the outside.

[0036] The lens 120 can be made of glass, resin, or high-refractive-index resin. The lens 120 can be a planar lens or a curved lens. In one embodiment, the lens 120 can also be a lens with a prescription; for example, the prescription of the lens 120 can be processed using a CNC (Computer Numerical Control) machine tool. An electrochromic element 160 is disposed on the side of the lens 120 near the anti-fog film 130 to form electrochromic glasses 100 with electrochromic function.

[0037] The anti-fog sheet 130 is used to reduce fog formation. Exemplarily, the anti-fog sheet 130 prevents light scattering caused by the formation of tiny water droplets by inhibiting or eliminating water vapor condensation on its surface. In one embodiment, the anti-fog sheet 130 can be made by coating a hydrophilic material (such as a polymer, nanomaterial, etc.) onto the surface of an ordinary lens. This hydrophilic material allows water vapor to spread evenly into a transparent water film instead of forming tiny water droplets when it condenses, thereby preventing blurring caused by light scattering. In another embodiment, the anti-fog sheet 130 can be made by forming a hydrophobic coating on the surface of an ordinary lens. Its water-repellent properties prevent water vapor from adhering, causing it to condense into larger water droplets that slide off, or evaporate directly on the surface, preventing the residue of tiny water droplets. In one embodiment, the surface of the anti-fog sheet 130 has a micro / nano structure (such as micron-level grooves or nanopillar arrays). This micro / nano structure alters the adhesion pattern of water, causing water vapor to be "guided" into a water film by the structure or to evaporate directly without forming water droplets.

[0038] In one embodiment, when the electrochromic glasses 100 are worn, the anti-fog lens 130 is located on the side closer to the human body, and the lens 120 is located on the side farther away from the human body.

[0039] It is understandable that when hot air encounters a cold object, water vapor in the air will liquefy on the object's surface, condensing into small water droplets and forming fog. Based on this, when using electrochromic glasses 100 in low-temperature environments such as snow, the temperature of the electrochromic glasses 100 is low, while the human body temperature is high. Placing an anti-fog film 130 on the side closest to the human body can reduce fog formation and keep the anti-fog film 130 clear.

[0040] In this embodiment, the lens 120 is connected to the lens frame 110 and sealed at the first opening 113 of the hollow cavity 115. The anti-fog film 130 is connected to the lens frame 110 and sealed at the second opening 114 of the hollow cavity 115. When wearing the electrochromic glasses 100, the anti-fog film 130 faces the human body, while the lens 120 faces the outside. The anti-fog film 130 serves as the hot side of the electrochromic glasses 100, and the lens 120 serves as the cold side. The lens 120 and the anti-fog film 130 are not in direct contact but are separated by the hollow cavity 115.

[0041] It is understandable that the heat transfer coefficient of air (still air: 0.02 W / (m·K)) is lower than that of solid materials (e.g., polyethylene: 0.45 W / (m·K), glass: 0.8 W / (m·K)). When cold outside air comes into contact with the lens 120, the lens 120 cools down rapidly. Because the lens 120 and the anti-fog film 130 are separated by the hollow cavity 115, the distance between the lens 120 and the anti-fog film 130 is relatively large, which reduces the heat conduction speed between the lens 120 and the anti-fog film 130. This results in a smaller temperature difference between the side of the anti-fog film 130 closer to the human body and the side farther away from the human body, reducing the occurrence of fogging on the anti-fog film 130 and enhancing its anti-fog effect.

[0042] The electrochromic element 160 is connected to the lens frame 110 and is located between the lens 120 and the anti-fog film 130. The lens 120 seals the first opening 113 and the anti-fog film 130 seals the second opening 114, thus delaying the oxidation effect of the electrochromic film on the outside air and stabilizing the effect of the electrochromic element 160.

[0043] The electrochromic element 160 is located within the hollow cavity 115, and a gap is formed between the lens 120 and / or the anti-fog film 130 and the electrochromic element 160. Specifically, the electrochromic element 160 may be attached to the lens 120, forming a gap between the electrochromic element 160 and the anti-fog film 130; or the electrochromic element 160 may be attached to the anti-fog film 130, forming a gap between the electrochromic element 160 and the anti-fog film 130; or the lens 120, the electrochromic film, and the anti-fog film 130 may be separated from each other, forming a gap between the electrochromic element 160 and the anti-fog film 130, and another gap is formed between the electrochromic element 160 and the anti-fog film 130.

[0044] It should be noted that because the lens 120 and the anti-fog film 130 are sealed to the lens frame 110, the airflow velocity in the gap is very low, reducing heat transfer efficiency. Furthermore, the gap can be filled with any one of air, inert gas, nitrogen, or carbon dioxide.

[0045] In this embodiment, the presence of gaps further reduces the heat conduction speed between the lens 120 and the anti-fog film 130, thereby making the temperature difference between the side of the anti-fog film 130 closer to the human body and the side farther away from the human body smaller, further enhancing the anti-fog effect of the anti-fog film 130.

[0046] In some embodiments, the first opening 113 and the second opening 114 are connected along the first direction D1.

[0047] It should be noted that the first direction D1 is perpendicular to the lens 120, which is also the direction in which light enters the lens 120 perpendicularly.

[0048] like Figure 1As shown, the hollow cavity 115 is connected along the first direction D1. The first opening 113 and the second opening 114 are located on opposite sides of the hollow cavity 115 along the first direction D1, and the axes of the first opening 113 and the second opening 114 coincide.

[0049] In one embodiment, the diameter of the first opening 113 is smaller than the diameter of the second opening 114.

[0050] like Figure 1 As shown, the lens frame 110 includes a first frame 111 and a second frame 112 connected along a first direction D1. Both the first frame 111 and the second frame 112 are annular, and the outer surfaces of the first frame 111 and the second frame 112 are flush, making the outer peripheral surface of the lens frame smooth and facilitating its encapsulation with the eyeglass frame.

[0051] The first opening 113 is located on the side of the first frame 111 away from the second frame 112, the second opening 114 is located on the side of the second frame 112 away from the first frame 111, the lens 120 is connected to the first frame 111, and the anti-fog lens 120 is connected to the second frame 112.

[0052] like Figure 1 As shown, the inner peripheral surface of the first frame 111 forms a first opening 113, and the inner peripheral surface of the second frame 112 forms a second opening 114. The inner diameter of the first frame 111 is smaller than the inner diameter of the second frame 112, so that the inner surface of the first frame 111 protrudes towards the outer surface of the second frame 112 relative to the inner surface of the second frame 112.

[0053] In some embodiments, the lens 120 is located outside the hollow cavity 115 and is fixed to the end face of the lens frame 110 opposite to the second opening 114. For example... Figure 1 As shown, the surface of the first frame 111 facing away from the second frame 112 has a larger surface area, which enables the lens 120 and the first frame 111 to form a more stable connection.

[0054] In some embodiments, such as Figure 1 As shown, the anti-fog sheet 130 is located inside the hollow cavity 115 and is fixed to the inner surface of the lens frame 110, which reduces the volume of the anti-fog sheet 130, reduces the weight, and also reduces the overall thickness of the lens 120 and the lens frame 110.

[0055] In some embodiments, such as Figure 1 As shown, the electrochromic element 160 is connected to the inner surface of the second frame 112 and to the end face of the first frame 111 facing the second frame 112. The anti-fog sheet 130 is connected to the inner surface of the second frame 112. The lens 120 is connected to the end face of the first frame 111 away from the second frame 112. A gap is formed between the electrochromic element 160 and the lens 120.

[0056] like Figure 1 As shown, the first frame 111 and the second frame 112 are connected along the first direction D1, and a stepped structure is formed at the connection between the first frame 111 and the second frame 112. The electrochromic element 160 is disposed inside the second frame 112 and pressed against the end face of the first frame 111, i.e., at the "stepped structure". The anti-fog sheet 130 is disposed inside the second frame 112 and is pressed against the end face of the first frame 111 by the electrochromic element 160, so that the first frame 111 can limit the electrochromic element 160 and the anti-fog sheet 130, reducing the risk of displacement of the electrochromic element 160 and the anti-fog sheet 130 within the second frame 112.

[0057] In addition, the gap between the electrochromic element 160 and the lens 120 can delay the transfer of heat from the anti-fog film 130 to the lens 120 side, keeping the anti-fog film 130 in a "constant temperature state" with a small temperature difference, reducing the occurrence of fogging on the anti-fog film 130 and enhancing the anti-fog effect.

[0058] In some embodiments, the electrochromic glasses 100 further includes a first adhesive layer 141 for bonding and fixing the anti-fog film 130 and the electrochromic element 160.

[0059] like Figure 1 As shown, the anti-fog sheet 130, the first adhesive layer 141 and the electrochromic element 160 are stacked in sequence, and the first adhesive layer 141 is used to fix the surfaces of the anti-fog sheet 130 and the electrochromic element 160 that are close to each other.

[0060] The first adhesive layer 141 completely fills the gap formed by the anti-fog sheet 130, the electrochromic element 160, and the second frame 112. Along the first direction D1, the orthographic projection of the first adhesive layer 141 overlaps with the orthographic projections of the anti-fog sheet 130 and the electrochromic element 160, making the bond between the anti-fog sheet 130 and the electrochromic element 160 more secure. Furthermore, the electrochromic element 160 is fixed to the anti-fog sheet 130 via the first adhesive layer 141. The anti-fog sheet 130 has high hardness and is not easily bent or deformed, thus providing support and stabilizing the shape of the electrochromic element 160.

[0061] The first adhesive layer 141 can be made of epoxy resin-based transparent adhesive, UV-cured transparent adhesive, silicone-based transparent adhesive, polyurethane-based transparent adhesive, or acrylic transparent adhesive.

[0062] like Figure 1 As shown, light passes through the anti-fog sheet 130 and enters the hollow cavity 115. After passing through the electrochromic element 160, the light exits from the lens 120. The visible range of the lens frame 110 is distributed in the area enclosed by the inner side of the first frame 111. The area of ​​the lens frame 110 is used to encapsulate the lens 120 and the anti-fog sheet 130 and is a non-visible area.

[0063] In some embodiments, the first adhesive layer 141 may also be configured as a ring.

[0064] When the first adhesive layer 141 is set in a ring shape, the first adhesive layer 141 can be made of a non-transparent adhesive material or a material with a similar color to the lens frame 110, and the inner surface of the first adhesive layer 141 can not exceed the inner surface of the first frame 111, so as to avoid reducing the visible range of the lens frame 110.

[0065] In addition, the annular first adhesive layer 141 leaves a gap between the anti-fog sheet 130 and the electrochromic element 160. This gap increases the total amount of gas in the hollow cavity 115, which helps to reduce the heat transfer efficiency between the electrochromic element 160 and the anti-fog element. This keeps the anti-fog sheet 130 in a "constant temperature state" with a small temperature difference for a long time, reduces the occurrence of fogging of the anti-fog sheet 130, and enhances the anti-fog effect.

[0066] In some embodiments, the electrochromic glasses 100 further include a first annular cushioning pad 142. For example... Figure 2 As shown, the first annular buffer pad 142 is disposed between the anti-fog sheet 130 and the electrochromic element 160. The outer peripheral surface of the first annular buffer pad 142 is connected to the inner surface of the second frame 112. The inner peripheral surface of the first annular buffer pad 142 forms another gap with the anti-fog sheet 130 and the electrochromic element 160. This gap also helps to reduce the influence of the outside environment on the temperature of the lens 120 and enhance the anti-fog effect.

[0067] The first annular buffer pad 142 is made of buffer foam adhesive, EVA (ethylene-vinyl acetate copolymer) foam, and PE (polyethylene) foam. In this way, when the anti-fog sheet 130 is fastened into the second frame 112, the first annular buffer pad 142 can provide good cushioning and reduce the risk of damage to the edges of the anti-fog sheet 130 during installation.

[0068] In one embodiment, the inner surface of the annular buffer pad is made not to exceed the inner surface of the first frame 111 to avoid reducing the visible range of the lens frame 110.

[0069] In some embodiments, the distance between the electrochromic element 160 and the lens 120 is greater than the distance between the electrochromic element 160 and the anti-fog film 130. like Figure 1 and Figure 2As shown, in the first direction D1, the lens 120, the electrochromic element 160, and the anti-fog film 130 are spaced apart. The distance between the electrochromic element 160 and the lens 120 is also set to be greater than the distance between the electrochromic element 160 and the anti-fog film 130, thereby reducing the distance between the anti-fog film 130 and the electrochromic element 160, reducing the occurrence of bright spots or uneven color distribution, and making the color-adjusting effect of the electrochromic glasses 100 better.

[0070] In addition, the enlargement between the electrochromic element 160 and the lens 120 can reduce the heat transfer efficiency between the lens 120 and the electrochromic element 160, thereby enhancing the anti-fog effect of the anti-fog film 130.

[0071] In some embodiments, the electrochromic glasses 100 further includes a second annular cushion 143 for protecting the electrochromic element 160.

[0072] like Figure 1 and Figure 2 As shown, the second annular buffer pad 143 is disposed between the first frame 111 and the electrochromic element 160, and the outer peripheral surface of the second annular buffer pad 143 is connected to the inner surface of the second frame 112. The two end faces of the second annular buffer pad 143 along the first direction D1 are respectively connected to the surface of the electrochromic element 160 near the lens 120 and the end face of the first frame 111 facing the second frame 112.

[0073] The second annular buffer pad 143 is located at the connection between the first frame 111 and the second frame 112. When the electrochromic element 160 is installed into the second frame 112, the second annular buffer pad 143 can provide good cushioning and reduce the edge of the electrochromic element 160 from being bumped or damaged during installation.

[0074] In another embodiment, the inner edge of the second annular buffer pad 143 does not exceed the inner edge of the first frame 111 to avoid reducing the visible range.

[0075] The second annular cushioning pad 143 is made of cushioning foam adhesive, EVA (ethylene-vinyl acetate copolymer) foam, and PE (polyethylene) foam.

[0076] In some embodiments, the electrochromic glasses 100 further include a third annular cushion 144 for protecting the lens 120.

[0077] like Figure 1 , Figure 2 As shown, the third annular buffer pad 144 is disposed between the lens 120 and the first frame 111, and the outer peripheral surface of the third annular buffer pad 144 is flush with the outer surface of the first frame 111.

[0078] The third annular buffer pad 144 is disposed on the end face of the first frame 111 opposite to the second frame 112, and the third annular buffer pad 144 is used to connect the lens 120 and the first frame 111.

[0079] The outer peripheral surface of the third annular buffer pad 144 is flush with the outer surface of the first frame 111, making the outer edge of the lens 120 and the lens frame 110 as a whole smooth, which is convenient for fitting into the frame and is compatible with more frame models; the inner peripheral surface of the third annular buffer pad 144 does not exceed the inner surface of the first frame 111, so as to avoid obstructing the field of vision and reducing the visible range.

[0080] In some embodiments, such as Figure 3 As shown, the anti-fog sheet 130 is connected to the inner surface of the second frame 112 and to the end face of the first frame 111 facing the second frame 112. The electrochromic element 160 is connected to the end face of the first frame 111 away from the second frame 112. The lens 120 is connected to the surface of the electrochromic element 160 away from the first frame 111. A gap is formed between the electrochromic element 160 and the anti-fog sheet 130.

[0081] This gap helps to reduce the heat transfer efficiency between the electrochromic element 160 and the anti-fog sheet 130, delays the heat transfer between the lens 120, the electrochromic element 160 and the anti-fog element, keeps the anti-fog sheet 130 in a "constant temperature state" with a small temperature difference, reduces the occurrence of fogging on the anti-fog sheet 130, and enhances the anti-fog effect.

[0082] In one embodiment, such as Figure 3 As shown, the outer peripheral surfaces of the electrochromic element 160 and the lens 120 are flush with the outer surface of the first frame 111, making the outer edges of the overall structure of the lens 120, electrochromic element 160 and lens frame 110 flat, which facilitates installation into the frame and compatibility with more frame models.

[0083] In some embodiments, such as Figure 3 As shown, the electrochromic glasses 100 further includes at least one of a first annular cushioning pad 142, a second annular cushioning pad 143, and a second adhesive layer 146, wherein: The first annular buffer pad 142 is disposed between the anti-fog sheet 130 and the first frame 111; The second annular buffer pad 143 is disposed between the first frame 111 and the electrochromic element 160; The second adhesive layer 146 is disposed between the lens 120 and the electrochromic element 160, and the second adhesive layer 146 is used to fix the surfaces of the lens 120 and the electrochromic element 160 that are close to each other.

[0084] Among them, such as Figure 3As shown, the outer peripheral surface of the first annular buffer pad 142 is connected to the inner surface of the second frame 112, and the end face of the first annular buffer pad 142 near the electrochromic element 160 is connected to the end face of the first frame 111 near the second frame 112.

[0085] like Figure 3 As shown, the second annular buffer pad 143 is disposed between the first frame 111 and the electrochromic element 160. In this embodiment, the second annular buffer pad 143 is disposed on the side of the first frame 111 away from the second frame 112. The electrochromic element 160 and the lens 120 are both disposed outside the hollow cavity 115 of the lens frame 110.

[0086] like Figure 3 As shown, along the first direction D1, the projection of the second adhesive layer 146 overlaps with the projection of the lens 120 and the projection of the electrochromic element 160. The electrochromic element 160 is fixed to the lens 120 by the second adhesive layer 146. The lens 120 has high hardness and is not easily bent or deformed. The lens 120 can support and stabilize the shape of the electrochromic element 160.

[0087] In one embodiment, such as Figure 3 As shown, the electrochromic glasses 100 include a second annular cushioning pad 143.

[0088] In one embodiment, such as Figure 3 As shown, the electrochromic glasses 100 include a first annular cushion 142 and a second annular cushion 143.

[0089] In one embodiment, such as Figure 3 As shown, the electrochromic glasses 100 include a first annular cushioning pad 142 and a second adhesive layer 146.

[0090] Please see Figure 4 In some embodiments, Figure 3 In this embodiment, the second adhesive layer 146 is replaced by a fourth annular buffer pad 145. The fourth annular buffer pad 145 is disposed between the lens 120 and the electrochromic element 160, and serves to buffer and reduce shock.

[0091] like Figure 4 As shown, the inner circumferential surface of the fourth annular buffer pad 145 forms another gap between the lens 120 and the electrochromic element 160. This gap helps to reduce the heat transfer efficiency between the electrochromic element 160 and the lens 120, thereby enhancing the anti-fog effect of the anti-fog film 130.

[0092] The fourth annular cushioning pad 145 can be made of cushioning foam, EVA (ethylene-vinyl acetate copolymer) foam, or PE (polyethylene) foam. At the same time, the inner surface of the fourth annular cushioning pad 145 must not exceed the inner surface of the first frame 111 to avoid reducing the visible range of the lens frame 110.

[0093] In some embodiments, such as Figure 5 As shown, the anti-fog sheet 130 is connected to the inner surface of the second frame 112 and to the end face of the first frame 111 facing the second frame 112. The lens 120 is connected to the end face of the first frame 111 away from the second frame 112. The electrochromic element 160 is connected to the surface of the lens 120 near the anti-fog sheet 130. This structure helps to reduce the overall volume of the lens 120 and the lens frame 110. When the electrochromic element 160 occupies too much volume in the hollow cavity 115, it reduces the volume of the remaining air in the hollow cavity 115. The total volume of the hollow cavity 115 can be increased by increasing the thickness of the third annular buffer pad 144, thereby increasing the amount of remaining air in the hollow cavity 115 and increasing the anti-fog effect.

[0094] like Figure 5 As shown, a gap is formed between the electrochromic element 160 and the anti-fog sheet 130. This gap helps to reduce the heat transfer efficiency between the electrochromic element 160 and the anti-fog sheet 130, reduce the occurrence of fogging on the anti-fog sheet 130, and enhance the anti-fog effect of the anti-fog sheet 130.

[0095] like Figure 5 As shown, in some embodiments, the outer peripheral edge of the electrochromic element 160 is spaced apart from the inner surface of the first frame 111. The electrochromic element 160 and the lens frame 110 are spaced apart, forming another gap between the electrochromic element 160 and the lens frame 110. This gap also helps to increase the amount of residual air in the hollow cavity 115 and enhance the anti-fog effect.

[0096] like Figure 5 As shown, in some embodiments, the electrochromic glasses 100 further includes a first annular buffer pad 142, which is disposed between the anti-fog film 130 and the first frame 111.

[0097] Continue reading Figure 5 The first annular buffer pad 142 is connected to the surface of the anti-fog sheet 130 near the electrochromic element 160, the end face of the first frame 111 facing the second frame 112, and the inner surface of the second frame 112.

[0098] Continue reading Figure 5 The inner surface of the first annular buffer pad 142 does not exceed the inner surface of the first frame 111, so as to avoid reducing the visible range of the lens frame 110.

[0099] Continue reading Figure 5 In some embodiments, the electrochromic glasses 100 further includes a second adhesive layer 146, which is disposed between the lens 120 and the electrochromic element 160, and is used to fix the surfaces of the lens 120 and the electrochromic element 160 that are close to each other.

[0100] like Figure 5 As shown, the second adhesive layer 146 completely fills the gap formed by the electrochromic element 160 and the lens 120, making the bond between the lens 120 and the electrochromic element 160 more secure.

[0101] The second adhesive layer 146 is made of epoxy resin-based transparent adhesive, UV-cured transparent adhesive, silicone-based transparent adhesive, polyurethane-based transparent adhesive, or acrylic transparent adhesive.

[0102] In some embodiments, the second adhesive layer 146 may also be configured as an annular shape.

[0103] In some embodiments, such as Figure 6 and Figure 7 As shown, the electrochromic element 160 includes an electrochromic film and a heat-bending layer 150.

[0104] like Figure 7 The electrochromic film includes a first protective layer 161, a first conductive layer 162, an electrochromic layer 163, a second conductive layer 164, and a second protective layer 165 stacked sequentially. For example... Figure 6 The hot-bending layer 150 is disposed on the side of the first protective layer 161 near the lens 120, or the hot-bending layer 150 is disposed on the side of the second protective layer 165 near the anti-fog sheet 130. The hot-bending layer 150 is bent and shaped after being softened by high temperature, which facilitates the overall shaping of the electrochromic component 160.

[0105] In such Figures 2-5 In the embodiments described, the heat-bending layer 150 may be located on the side of the electrochromic element 160 near the lens 120 or on the side near the anti-fog film 130.

[0106] In one implementation, such as Figures 1-5 In the described embodiment, the electrochromic element 160 includes two heat-bending layers 150. One heat-bending layer 150 may be located on the side of the first protective layer 161 near the lens 120, and the other heat-bending layer is located on the side of the second protective layer 165 near the anti-fog film 130.

[0107] In some embodiments, the electrochromic glasses 100 also include a lead-out circuit board 170 and a docking element 180.

[0108] like Figure 1As shown, the lead-out circuit board 170 is electrically connected to the electrochromic element 160. A first receiving groove 116 is formed on the end face of the second frame 112 away from the first frame 111. The lead-out circuit board 170 is disposed within the first receiving groove 116, making efficient use of space and making the structure of the electrochromic glasses 100 more compact. Specifically, there are two lead-out circuit boards 170, which are respectively connected to the first conductive layer 162 and the second conductive layer 164. Figure 7 Only one lead-out circuit board 170 connected to the second conductive layer 164 is shown in the diagram.

[0109] Electrical connection with the outside is achieved by setting the docking element 180. For example... Figure 1 One end of the docking element 180 is connected to the lead-out circuit board 170 in the first receiving groove 116, and the other end of the docking element 180 is located outside the first receiving groove 116 and protrudes from the end face of the second frame 112 away from the first frame 111.

[0110] In one embodiment, the electrochromic glasses 100 further includes a frame for securing the glasses 100 to the user's head. The end face of the second frame 112, away from the first frame 111, is used to secure it to the frame. The frame includes an electrically connected power supply and controller, and a docking element 180 is used for electrical connection to the controller. When the docking element 180 is electrically connected to the controller, the controller is electrically connected and / or communicatively connected to the electrochromic element 160 via the docking element 180.

[0111] For example, when the controller is electrically connected to the electrochromic element 160, the controller receives power from the power source and transmits current to the electrochromic element 160 to regulate the transmittance of the electrochromic element 160. When the controller is communicatively connected to the electrochromic element 160, the controller reads the identification information of the electrochromic element 160 and determines the control logic for controlling the electrochromic element 160 based on the identification information.

[0112] In some embodiments, such as Figure 1 As shown, the electrochromic glasses 100 also includes a magnetic clasp 190. A second receiving groove 117 is formed on the surface of the second frame 112 away from the first frame 111, and the magnetic clasp 190 is fixed in the second receiving groove 117. The magnetic clasp 190 is used to fix the surface of the second frame 112 away from the first frame 111 to the frame, so as to realize the detachable connection between the frame and the lens frame 110. In one embodiment, at least some of the magnetic clasp 190 are arranged around the docking element 180. When the docking element 180 forms an electrical connection with the external connector, the magnetic clasp 190 can attract external metal objects or magnetic objects, making the connection of the docking element 180 more stable and less likely to fall off.
