[0036] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element, or one or more intermediate elements may exist between them.

[0037] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0038] Please see Figure 1 and Figure 2 This application provides a smart glasses 100, including a glasses frame 1, a camera 2, an electrochromic module 3, and a controller 4. The camera 2 is disposed on the glasses frame 1. The electrochromic module 3 is disposed in front of the camera 2. The controller 4 is electrically connected to the electrochromic module 3 and is used to control the electrochromic module 3 to switch between a transparent color and a preset color. By setting the electrochromic module 3, the camera 2 can be exposed when the electrochromic module 3 is in a transparent state, and the camera 2 can be obscured when the electrochromic module 3 is in a preset color, thereby improving the privacy protection capability of the smart glasses 100. In addition, the electrochromic module 3 provided in this application switches between a transparent color and a preset color through the controller 4, thereby exposing or obscuring the camera 2; it does not require the mechanical structure relying on a drive mechanism to achieve the exposure or obscuring of the camera 2 in the prior art, overcoming the problems of the large size and space occupation of the mechanical structure in the prior art.

[0039] Among them, the smart glasses 100 in the embodiments of this application include AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, or MR (Mixed Reality) glasses, etc.

[0040] It is understandable that the eyeglasses frame 1 may include a power module 5 for supplying power to the camera 2, the electrochromic module 3, and the controller 4.

[0041] In this context, "front of camera 2" refers to the direction that camera 2 faces when in normal use, that is, the side of camera 2 facing the external environment when the smart glasses 100 are worn on the user's head.

[0042] The controller 4 can be installed on the eyeglass frame 1, or the controller 4 can be installed separately from the eyeglass frame 1, as long as it can control the electrochromic module 3.

[0043] In some embodiments, the eyeglass frame 1 has two temples 101 arranged opposite each other, and when the user wears the smart glasses 100, the temples 101 support the user's ears. The controller 4 is disposed in one of the temples 101, and the power module 5 is disposed in the other temple 101.

[0044] It is worth noting that the program steps involved in the controller 4 in the embodiments of this application are existing program steps, and the controller 4 also uses existing processors, such as Intel's i3 processor, AMD Ryzen processor, etc.

[0045] In this embodiment of the application, "transparent color" refers to a color with a light transmittance greater than or equal to 80%, and "transparent" refers to a light transmittance greater than or equal to 80%.

[0046] The preset color is opaque, meaning it can be any color with a light transmittance of less than 80%.

[0047] In some embodiments, the preset color is black.

[0048] In some embodiments, the preset color is at least the same color as the eyeglasses frame 1 where the camera 2 is located, such as gray, metallic, blue, white, etc.

[0049] In some embodiments, the eyeglass frame 1 has a front frame 102, which refers to the frame of the eyeglass frame 1 facing away from the user's face when the user wears the smart glasses 100. The camera 2 is disposed on the front frame 102, and the preset color is consistent with the color of the front frame 102. For example, if the front frame 102 is blue, then the preset color is blue. Or, for example, if the front frame 102 is metallic, then the preset color is metallic. Through this setting, when the electrochromic module 3 switches to the preset color, it is consistent with the overall appearance of the front frame 102 of the eyeglass frame 1, improving the concealment effect of the camera 2.

[0050] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 3 and combined Figure 2 The electrochromic module 3 includes a stacked conductive layer 301 and a color-changing layer 302. The conductive layer 301 is transparent and electrically connected to the controller 4. The controller 4 controls the application of an electrical signal to the conductive layer 301, causing the color-changing layer 302 to switch between a transparent color and a preset color under the influence of the electrical signal. When the conductive layer 301 gains electrons through the controller 4, these electrons are transferred to the color-changing layer 302, causing a reduction reaction and displaying the preset color. Conversely, when the color-changing layer 302 loses electrons through the conductive layer 301 and the controller 4, it undergoes an oxidation reaction and switches to a transparent color.

[0051] The electrical signal includes voltage, which is used to switch the color of the color-changing layer 302. This voltage is used to switch the color of the color-changing layer 302, and the specific value of the voltage can be reasonably set according to actual needs; this application does not impose specific limitations.

[0052] In some embodiments, the voltage is between 0V and 5V. For example, the controller 4 controls the application of a 3V or 3.5V voltage to the conductive layer 301, which can cause the color-changing layer 302 to switch from transparent to black within 1 second. When the voltage is removed or the controller 4 controls the application of a reverse voltage to the conductive layer 301, the color-changing layer 302 switches back to transparent.

[0053] In the specific implementation process, the response time of the electrochromic module 3 can be optimized and adjusted according to actual needs. However, in general, color switching can be achieved within 1 second. In actual use, the smart glasses 100 provided in this application embodiment has a fast response speed for revealing or hiding the camera 2.

[0054] In addition, it is worth noting that when the controller 4 controls the color-changing layer 302 of the electrochromic module 3 to switch between transparent color and preset color, the energy consumption of a single switch is less than 2mAh. The smart glasses 100 provided in this application embodiment has low energy consumption when the camera 2 is exposed or hidden.

[0055] It is worth noting that in some embodiments, the color-changing layer 302 is made of an organic small-molecule electrochromic material, such as phthalooxide. Phthalooxide has excellent electrochromic properties and can switch between transparent and black. It is also worth noting that the color-changing layer 302 can switch to any of the preset colors, such as black, gray, blue, metallic, or white. The preset color of the color-changing layer 302 is related to its material. For example, if the material of the color-changing layer 302 is phthalooxide, then the color-changing layer 302 switches between transparent and black; if the material of the color-changing layer 302 is Prussian blue, then the color-changing layer 302 switches between transparent and blue.

[0056] It is worth noting that in some embodiments, the color-changing layer 302 is doped with glass spheres with a diameter of less than 0.05 mm to improve the mechanical strength of the color-changing layer 302. When a certain mechanical strength is required, the thickness of the color-changing layer 302 can be reduced by adding glass spheres.

[0057] It is worth noting that in some embodiments, the color-changing layer 302 is disposed facing the camera 2, while the conductive layer 301 is disposed facing away from the camera 2. The conductive layer 301 not only serves as a transmission medium for electrical signals but also protects the color-changing layer 302, preventing damage to the color-changing layer 302 from the external environment, thereby extending the service life of the electrochromic module 3.

[0058] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 4 The conductive layer 301 includes a substrate layer 3011 and a conductive coating 3012 disposed on the substrate layer 3011. The substrate layer 3011 is transparent, and the conductive coating 3012 is transparent. The conductive coating 3012 is located between the substrate layer 3011 and the color-changing layer 302, and is electrically connected to the controller 4. The substrate layer 3011 provides support and can be made of glass or plastic, such as PC (Polycarbonate) or PMMA (Polymethyl Methacrylate). The conductive coating 3012 is made of ITO (Indium Tin Oxide), which has good conductivity and transparency, effectively transmitting electrical signals without affecting the overall light transmittance of the conductive layer 301.

[0059] In some embodiments, the thickness of the substrate layer 3011 is 0.35 mm, the thickness of the color-changing layer 302 is 0.1 mm, and the overall thickness of the electrochromic module 3 is less than 0.5 mm, which makes the entire electrochromic module 3 have a thinner structural design, which is beneficial to the overall thinness and lightness of the smart glasses 100.

[0060] In some embodiments, please refer to Figure 4 The electrochromic module 3 further includes an antireflective film 303, which is disposed on the side of the color-changing layer 302 facing away from the conductive layer 301, and / or, the antireflective film 303 is disposed on the side of the conductive layer 301 facing away from the color-changing layer 302. By providing this antireflective film 303, the reflection of light in the electrochromic module 3 can be effectively reduced, thereby improving the light transmittance of the electrochromic module 3.

[0061] In some embodiments, please refer to Figure 4 The electrochromic module 3 further includes an antireflective film 303 and an anti-fingerprint coating 304 disposed on the antireflective film 303. The antireflective film 303 is disposed on the side of the color-changing layer 302 facing away from the conductive layer 301, and / or, the antireflective film 303 is disposed on the side of the conductive layer 301 facing away from the color-changing layer 302. The antireflective film 303 effectively reduces light reflection in the electrochromic module 3, thereby improving the light transmittance of the electrochromic module 3. The anti-fingerprint coating 304 effectively prevents fingerprints from adhering to the electrochromic module 3, improving the user experience.

[0062] It is worth noting that, in this embodiment, the electrochromic module 3 is positioned in front of the camera 2 to reveal or hide the camera 2, wherein the camera 2 is mounted on the eyeglass frame 1. However, this embodiment does not limit the positional relationship between the electrochromic module 3 and the eyeglass frame 1, thus achieving the purpose of revealing or hiding the camera 2. For example, the camera 2 may be located on the eyeglass frame 1, and the electrochromic module 3 may be positioned in front of the camera 2, but the electrochromic module 3 may not be mounted on the eyeglass frame 1. Alternatively, the electrochromic module 3 may also be mounted on the eyeglass frame 1. For example, in some embodiments, please refer to... Figure 2 and combined Figure 1 The eyeglass frame 1 has a receiving cavity 1a and an opening 1b communicating with the receiving cavity 1a. The camera 2 is disposed in the receiving cavity 1a, and the electrochromic module 3 is exposed in the opening 1b. The camera 2 and the electrochromic module 3 are both housed in the receiving cavity 1a. The eyeglass frame 1 protects the camera 2, and through the opening 1b, when the electrochromic module 3 is transparent, the camera 2 can capture images of the external environment.

[0063] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 5 The eyeglass frame 1 has a nose pad 103, and the opening 1b is located at the front of the eyeglass frame 1 and above the nose pad 103. When the user wears the smart glasses 100, the nose pad 103 rests against the user's nose bridge. Here, "front of the eyeglass frame 1" refers to the side of the eyeglass frame 1 facing away from the user's face when the user wears the smart glasses 100; "the opening 1b is located above the nose pad 103" means that when the user wears the smart glasses 100 upright, in the opposite direction of gravity, the opening 1b is located above the nose pad 103.

[0064] In some embodiments, the nose pad 103 is centered relative to the two temples 101 of the eyeglass frame 1. When the opening 1b is positioned above the nose pad 103, the camera 2 can capture objects within the user's field of vision.

[0065] In some embodiments, please refer to Figure 6 and combined Figure 2 and Figure 3 The smart glasses 100 also includes a support 6, which is disposed in the receiving cavity 1a. The support 6 has a first mounting portion 601 with a groove 6011. The electrochromic module 3 is disposed in the groove 6011. Through the groove 6011, the electrochromic module 3 is sandwiched between the groove 6011 and the glasses frame 1, thereby achieving a stable installation of the electrochromic module 3. The structural design of the groove 6011 effectively restricts the displacement of the electrochromic module 3, improving the stability and reliability of the electrochromic module 3 in the smart glasses 100.

[0066] In some embodiments, the bracket 6 may be omitted, and the electrochromic module 3 may be fixed to the eyeglass frame 1 by means of fasteners (not shown).

[0067] In some embodiments, please refer to Figure 7 and combined Figure 2 , Figure 3 and Figure 6 The bracket 6 also has a second mounting portion 602 disposed opposite to the first mounting portion 601, and the camera 2 is mounted on the second mounting portion 602. The bracket 6 has a through hole 61 connecting the groove 6011 and the second mounting portion 602, and the camera 2 is exposed in the through hole 61 so that the electrochromic module 3 disposed in the groove 6011 is positioned in front of the camera 2. The bracket 6 not only provides support for the electrochromic module 3, but also enables the camera 2 to be mounted via the second mounting portion 602.

[0068] In some embodiments, the second mounting part 602 is provided with a mounting groove 6021, and the camera 2 is disposed in the mounting groove 6021. The through hole 61 penetrates the bottom of the groove 6011 and the bottom of the mounting groove 6021. Through the mounting groove 6021, the camera 2 is mounted in the mounting groove 6021, thereby achieving a stable installation of the camera 2. At the same time, the mounting groove 6021 can effectively limit the displacement of the camera 2, improving the assembly stability and reliability of the camera 2 in the smart glasses 100.

[0069] It is understandable that the bracket 6 mentioned above may not be used, and the camera 2 may be fixed to the eyeglass frame 1 by means of fasteners (not shown).

[0070] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 3 and combined Figure 2 and Figure 7 The smart glasses 100 also includes a buffer 7, which is disposed between the second mounting part 602 and the camera 2. The camera 2 is mounted on the second mounting part 602 via the buffer 7. The buffer 7 can be an elastic material such as foam or rubber. By setting the buffer 7, an elastic support can be formed between the camera 2 and the bracket 6, thereby reducing the impact of external impacts on the camera 2 and improving the service life and stability of the camera 2.

[0071] It is understandable that the shape of the buffer 7 is adapted to the contact surface between the second mounting part 602 and the camera 2. For example, the second mounting part 602 is provided with a cylindrical mounting groove 6021, and the buffer 7 is annular. The buffer 7 is located between the outer periphery of the camera 2 and the second mounting part 602.

[0072] In some embodiments, please refer to Figure 3 and combined Figure 2 The smart glasses 100 also includes a conductive component 8, which electrically connects the controller 4 and the electrochromic module 3. The conductive component 8 enables the electrical connection between the electrochromic module 3 and the controller 4. The conductive component 8 can be any one of a flexible flat cable, a conductive wire, or a conductive sheet.

[0073] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 8 The smart glasses 100 also includes a distance sensor 9 disposed on the eyeglass frame 1. The distance sensor 9 is electrically connected to the controller 4. When the distance sensor 9 detects preset information, the controller 4 controls the electrochromic module 3 to switch between the transparent color and the preset color. The preset information detected by the distance sensor 9 may be the distance information from the user's hand to the distance sensor 9 when the user raises their hand. Raising the hand can trigger the camera 2 to be revealed or hidden. Through this setting of the distance sensor 9, when the user raises their hand, the distance sensor 9 detects the distance information of the user's hand, and the controller 4 controls the electrochromic module 3 to switch to the transparent color or the preset color, thereby revealing or hiding the camera 2 and improving the user's interactive experience with the smart glasses 100.

[0074] It's worth noting that the way camera 2 is triggered to appear or disappear is not limited to the user raising their hand. It can also be triggered by the user's voice commands (using the microphone on the smart glasses 100), button commands (using the touchpad or buttons on the smart glasses 100), or by the gyroscope on the smart glasses 100 detecting specific user actions, such as looking up, nodding, or shaking their head. For example, when the user triggers functions related to camera 2, such as live streaming or shooting, via voice command, controller 4 controls the electrochromic module 3 to switch to transparent, revealing camera 2. When the user triggers the shutdown of functions related to camera 2 via voice command, controller 4 controls the electrochromic module 3 to switch to a preset color, hiding camera 2.

[0075] In addition, to conserve power, if the gyroscope detects that the user has not moved for an extended period (e.g., 10 minutes), the controller 4 will put the electrochromic module 3 into a standby state. The standby state of the electrochromic module 3 means that it maintains its current color state and no longer responds to external signals or commands until the camera 2 is triggered to reveal or hide. When the electrochromic module 3 is in standby state, its power consumption is close to zero, thereby extending the battery life of the smart glasses 100 and improving the user experience.

[0076] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 8 and combination Figure 2 The smart glasses 100 also includes an indicator light 11 and a light guide 12 disposed on the front frame 102 of the eyeglasses frame 1. The indicator light 11 is disposed on the eyeglasses frame 1, and the light guide 12 is exposed on the front frame 102. The light guide 12 is located on the light propagation path of the indicator light 11, and conducts the light signal of the indicator light 11 to the outside of the front frame 102 through the light guide 12. The indicator light 11 is electrically connected to the controller 4, which is used to control the working state of the indicator light 11. For example, when the camera 2 is exposed, the indicator light 11 displays a color (e.g., red) to indicate to the user that the camera 2 is in working state. When the camera 2 is hidden, the indicator light 11 is turned off or switches to another color.

[0077] In some embodiments, the indicator light 11 is located on one side of the front frame 102, and the distance sensor 9 is positioned close to the indicator light 11.

[0078] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 8 and combination Figure 2 The smart glasses 100 also includes an optical sensor 10 disposed on the eyeglass frame 1. The optical sensor 10 is electrically connected to the controller 4. The optical sensor 10 is used to detect the brightness data of ambient light. The controller 4 is used to control the light transmittance of the electrochromic module 3 according to the brightness data, so that the electrochromic module 3 can match the brightness of the current environment even when it is in a preset color, thereby effectively hiding the camera 2 under different lighting conditions. For example, when the brightness data is 10000 lux, the light transmittance of the electrochromic module 3 is controlled to be 60%; when the brightness data is 1000 lux (medium light during cloudy daytime), the light transmittance of the electrochromic module 3 is controlled to be 20%. The controller 4 controls and adjusts the light transmittance of the electrochromic module 3 by adjusting the voltage applied to the electrochromic material.

[0079] In some embodiments, the indicator light 11 is located on one side of the front frame 102, and the optical sensor 10 is disposed close to the indicator light 11.

[0080] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 8 The smart glasses 100 also includes a communication interface 13 disposed on the eyeglass frame 1. The communication interface 13 is electrically connected to the controller 4 and is used to interact with external devices. Through this communication interface 13, remote control of the controller 4 can be achieved, for example, by connecting the controller 4 to smartphones, smartwatches, etc., via Bluetooth or Wi-Fi modules. The firmware of the controller 4 can also be upgraded through this communication interface 13.

[0081] It is worth noting that in some embodiments, the eyeglass frame 1 integrates an electrochromic lens (not shown), which is electrically connected to the controller 4. The electrochromic lens has the same structure and control principle as the electrochromic module 3, and the appearance of the eyeglass frame 1 is adjusted by controlling the color change of the electrochromic lens. In some embodiments, the controller 4 controls the color switching of the electrochromic module 3 and the electrochromic lens separately, that is, the electrochromic module 3 and the electrochromic lens are controlled independently. When the electrochromic module 3 needs to switch between transparent and preset colors, it does not affect the color switching of the electrochromic lens; when the electrochromic lens needs to switch colors, it does not affect the color switching of the electrochromic module 3. When the color of the electrochromic module 3 is switched, the color of the electrochromic lens is not switched, or when the color of the electrochromic lens is switched, the color of the electrochromic module 3 is not switched, thereby achieving independent functional control and saving energy.

[0082] It is worth noting that in some embodiments, please refer to [link / reference]. Figure 5 The eyeglass frame 1 also includes a lens 104, which integrates an electrochromic lens (not shown). The electrochromic lens is electrically connected to a controller 4. The electrochromic lens has the same structure and control principle as the electrochromic module 3, and the appearance of the lens 104 is adjusted by controlling the color change of the electrochromic lens. In some embodiments, the lens 104 not only has a waveguide display function, but also a diopter adjustment function, as well as the color-changing function provided by the aforementioned electrochromic lens, thereby realizing a multi-functional intelligent experience.

[0083] To facilitate readers' understanding of the design concept of the smart glasses 100 equipped with the electrochromic module 3 of this application, one method of using the smart glasses 100 is described below: When a user wears smart glasses 100 and the smart glasses 100 is powered on, the gyroscope (not shown) detects the user's head movements. When the detected head movements meet preset trigger conditions (e.g., the gyroscope detects a head tilt), the controller 4 applies a 3.5V voltage to the electrochromic module 3. The electrochromic module 3 switches to transparent within 1 second. The camera 2 captures an environmental image, which is superimposed on the image displayed by the optical engine (not shown) in the smart glasses 100 and projected onto the lens 104. When functions related to the camera 2 (e.g., live streaming or shooting) are turned off, the controller 4 controls the removal of the voltage applied to the electrochromic module 3, or the controller 4 controls the application of a reverse voltage to the electrochromic module 3, causing the electrochromic module 3 to switch to a preset color.

[0084] It is understood that the application scenarios of the smart glasses 100 equipped with the electrochromic module 3 provided in this application embodiment can be video conferencing, gaming, secure payment, and other scenarios.

[0085] When a video conference begins, camera 2 is displayed to prevent participants from mistakenly believing they are being continuously monitored.

[0086] During gameplay, controller 4 can receive commands via network to switch the color of electrochromic module 3. Controller 4 controls the voltage applied to electrochromic module 3 to control the switching of the color (or light transmittance) of electrochromic module 3, thereby enhancing the gaming experience.

[0087] In secure payment scenarios, when camera 2 needs to scan a payment QR code, the electrochromic module 3 only switches to transparent when the user actively triggers the payment instruction. When the user does not actively trigger the payment instruction, the electrochromic module 3 maintains the preset color to prevent malicious software from accessing camera 2 for an extended period and to improve payment security.
