It should be understood that the technical features involved in the various embodiments of the invention described below can be combined with each other, provided that no conflict is established.

[0023] Please refer to the following: Figures 1 to 4 , Figures 1 to 4 A schematic diagram of the structure of smart glasses provided in some embodiments of this utility model is shown.

[0024] Specifically, such as Figures 1 to 4 As shown, the smart glasses 100 includes temples 10, a frame 20, a light source 30, and lenses 40. The frame 20 is connected and fixed to the temples 10, wherein the first end of the temples 10 is connected and fixed to the frame 20.

[0025] For example, the frame 20 includes a main frame 21 and a fixed frame 22. The main frame 21 is provided with a first mounting opening 211, a mounting portion 212, and a frame portion 213. The mounting portion 212 extends from the inner wall of the first mounting opening 211 in a direction away from the frame portion 213. The fixed frame 22 is provided with a second mounting opening 221. The size of the lens 40, the size of the first mounting opening 211, and the size of the second mounting opening 221 are adapted to each other, that is, the size of the lens 40, the size of the first mounting opening 211, and the size of the second mounting opening 221 are the same or similar, so that the lens 40 can be embedded and fixed in the first mounting opening 211 and the second mounting opening 221.

[0026] Please refer to the following: Figure 2 , Figure 4 as well as Figure 5The light source 30 is disposed in the main frame 21. In this embodiment of the invention, the light source 30 is specifically disposed within the frame portion 213 of the main frame 21, and the light source 30 is used to emit light. It is easy to understand that the light source 30 can be any suitable type of light source, such as an LED light source, a laser light source, etc.

[0027] Specifically, the thickness of the lens 40 matches the width of the mounting portion 212, and the lens 40 is embedded and fixed in the mounting portion 212. Matching the thickness of the lens 40 with the width of the mounting portion 212 means that the thickness of the lens 40 is the same as or similar to the width of the mounting portion 212, so that the lens 40 can be embedded and fixed in the mounting portion 212.

[0028] For example, after the lens 40 is installed and fixed to the frame 20, the fixing frame 22 is connected and fixed to the main frame 21, and the second mounting port 221 is aligned with the first mounting port 211, so that the lens 40 is installed and fixed to the frame 20.

[0029] In this embodiment, the lens 40 includes a waveguide layer 41 and a holographic film 42 that are bonded together. The holographic film 42 is bonded to the side of the waveguide layer 41 away from the light source 30. The holographic film 42 has a preset display pattern, which can be a camera viewfinder (such as...). Figure 6a The holographic film 42, which includes the viewfinder, operation prompts, or brand logo shown, is a thin film material made based on the principle of holographic imaging. The pattern to be displayed is pre-exposed in the holographic film 42 through optical exposure. The light emitted from the light source 30 is directed to the waveguide layer 41. The light entering the waveguide layer 41 is reflected by the waveguide and transmitted to the exiting waveguide layer 41. The light is then output from the exiting waveguide layer 41. The holographic film 42 diffracts the light emitted from the waveguide layer 41 (i.e., the light output from the exiting waveguide layer 41) to display the preset display pattern on the preset area of ​​the lens 40. In other words, the holographic film 42 displays the built-in preset display pattern on the lens 40 by diffracting the light emitted from the waveguide layer 41.

[0030] The preset area of ​​the lens 40 can be any suitable area such as the edge area, middle area or corner area of ​​the lens 40. The preset display pattern set in the holographic film 42 includes one or more. The display area, display duration and display brightness of each preset display pattern may be the same or different. Engineers can set the display parameters (including display area, display duration and display brightness, etc.) of all preset display patterns according to actual needs.

[0031] It is understandable that this utility model utilizes low-adhesion holographic film technology (peel force). The holographic film 42 (20gf / 25mm) is custom-fitted onto the inner or outer curved surface of the waveguide layer 41 to adapt it to lenses with different curvatures (such as automotive windshields, refractive lenses, etc.). This allows the holographic film 42 to be applied to more optical product scenarios, such as automotive holographic displays and eyeglass optical decorations, expanding its application range. Furthermore, the holographic film 42 supports use in environments ranging from -30℃ to 80℃ and is resistant to environmental humidity. It can work stably in diverse and complex environments such as cold, heat, and humidity, ensuring the long-lasting holographic effect, improving product reliability and service life, and reducing problems such as failure and detachment caused by environmental changes.

[0032] Please refer to the following: Figure 1 , Figure 2 and Figure 5 In some embodiments, the frame portion 213 includes a mounting shell 2131 and a mounting hole 2132. The mounting portion 212 is provided with an external protrusion 2121 at a position corresponding to the mounting hole 2132. The waveguide layer 41 includes a first ear portion 41d, and the fixed frame 22 also includes a second ear portion 222.

[0033] For example, after the lens 40 is mounted and fixed to the frame 20, the dimensions of the first ear 41d, the second ear 222, and the outer protrusion 2121 are adapted to each other (i.e., the dimensions of the first ear 41d, the second ear 222, and the outer protrusion 2121 are the same or similar), so that the first ear 41d and the second ear 222 are embedded and fixed in the outer protrusion 2121. The light source 30 is mounted in the mounting housing 2131, and the light emitted by the light source 30 is emitted along the mounting hole 2132, that is, emitted along the mounting hole 2132 to the waveguide layer 41.

[0034] In this embodiment, by providing a mounting shell 2131 to protect the light source 30, damage to the light source 30 is reduced or avoided, dust or solid particles are reduced from entering the light source 30, the cleanliness of the light source 30 is ensured, and the service life of the light source 30 is extended.

[0035] Please see Figure 1 , Figure 3 or Figure 4 In some embodiments, the smart glasses 100 further includes a fastener 50, wherein the size of the fastener 50 is adapted to the size of the holographic film 42 and the size of the second mounting opening 221, that is, the size of the fastener 50 is the same as or similar to the size of the holographic film 42 and the size of the second mounting opening 221, so that the fastener 50 can be embedded around the periphery of the holographic film 42. For example, after the lens 40 is mounted and fixed to the frame 20, the fastener 50 is fixedly mounted to the second mounting opening 221, and the fastener 50 is embedded around the periphery of the holographic film 42.

[0036] In this embodiment, by setting the fixing member 50 around and embedding it around the periphery of the holographic film 42, the holographic film 42 is further stably fixed on the waveguide layer 41, thereby improving the stability of the pattern display and enhancing the user experience. At the same time, it avoids direct contact between the fixing frame 22 and the holographic film 42, thus protecting the holographic film 42 to a certain extent and ensuring that the performance of the holographic film 42 is not affected.

[0037] Please refer to the following: Figure 6b and Figure 6c In some embodiments, the holographic film 42 includes a holographic sheet 421 and a protective film 422. A preset display pattern is set on the holographic sheet 421, the protective film 422 is attached to a first side of the holographic sheet 421, and the waveguide layer 41 is attached to a second side of the holographic sheet 421. The protective film 422 is used to protect the holographic sheet 421 and reduce or avoid friction damage to the holographic sheet 421.

[0038] It should be understood that engineers can pre-expose the desired pattern onto the hologram 421 using optical exposure, and then attach a protective film 422 to the hologram 421 to obtain a hologram 42, thereby forming a preset display pattern on the hologram 42. In some embodiments, please refer to... Figure 6d The process of making hologram 421 is as follows: 1) The laser emits laser light, which has high coherence, good directionality, and strong monochromaticity, making it a key light source for holographic recording of interference fringes; 2) The beam splitter divides the laser emitted by the laser into two beams: a reference beam and an object beam; 3) The reference beam is projected through a reference optical path (including a beam expander and a lens) to uniformly illuminate the hologram. That is, the beam expander extends the reference beam, forming an extended beam, and the lens uniformly projects this extended beam onto the hologram; 4) The object beam is first reflected by a mirror to change direction, and then expanded by the beam expander to form an extended beam. 5) After the expanded beam of the object ray passes through the reticle, it is focused by the objective lens, projecting the pattern information in the reticle onto the hologram; 6) At the position of the hologram, the object ray and the reference ray projected onto the hologram meet and interfere, forming an interference pattern. The interference pattern is the intensity distribution formed by the superposition of the object ray (i.e., the ray containing the amplitude and phase information of the object) and the reference ray. The interference pattern is recorded on the photosensitive material (e.g., silver halide photosensitive film, photosensitive polymer film, etc.) to form the latent image of the hologram; 7) After exposure, the hologram is processed by developing, fixing, washing and other processes to fix the interference pattern structure, thereby obtaining a hologram with a preset display pattern.

[0039] The core of holographic fabrication lies in simultaneously recording the amplitude and phase information of light waves, achieving phase information preservation through interference and diffraction. The principle of interference recording is as follows: The electric field distribution of light rays from an object can be represented as:

[0040] The electric field distribution of the reference ray can be written as:

[0041] The total light intensity of the two beams on the hologram is:

[0042] The total light intensity includes cross terms. Cross terms It serves as a carrier of phase information. By utilizing the photosensitive material's response to light intensity, the spatial distribution of the interference pattern is recorded, resulting in a usable hologram. During the interference recording process, the light field information of the object (i.e., the pattern in the reticle of this embodiment) is converted into bright and dark fringes and phase information in the interference pattern, thereby recording the object's three-dimensional shape and illumination information. It is easily understood that during the interference exposure process, engineers can select appropriate exposure wavelengths, light energy densities, etc., according to actual needs.

[0043] After the hologram is fabricated, it diffracts the light beam to display the set pattern. The principle of diffraction reconstruction is as follows: the hologram (or holographic film) is illuminated with the same light wave as the original reference light. The light beam is decoded by the interference pattern recorded in the hologram / holographic film. Through the action of the interference pattern, the light field information of the original pattern is reproduced, forming a three-dimensional and realistic holographic image. The human eye or imaging system can see the same three-dimensional image (including depth of field and parallax) as the original pattern from different angles. The general process of the holographic film 42 diffracting light to display the preset pattern is as follows: the light source 30 is lit, and part of the light transmitted by the waveguide layer 41 leaks → the grating in the holographic film 42 selectively diffracts the light → a static preset pattern is projected and displayed in the preset area of ​​the lens 40 (e.g., the edge area of ​​the lens 40) → the preset pattern is presented to the human eye by the imaging system, so that the human eye can observe the preset pattern.

[0044] It should be understood that engineers can adjust the period of the grating in the holographic film 42 according to actual needs to match the wavelength of the light leaked when the waveguide layer 41 transmits light, thereby improving the light leakage utilization and the diffraction efficiency of the grating.

[0045] In some embodiments, the holographic sheet 421 includes a multilayer structure comprising a transparent substrate, a low-adhesion layer, an optical film layer, and a photopolymer layer. A preset display pattern is exposed on the photopolymer layer; that is, the preset display pattern is exposed on the photopolymer layer by laser interference to form a volume holographic grating. The precision of the preset display pattern reaches the micrometer level. It is easy to understand that the transparent substrate can be made of materials such as PET (polyethylene terephthalate) / COP (cycloolefin polymer), and the optical film layer can be made of materials such as TAC (triacetyl cellulose) / PMMA (polymethyl methacrylate). The thickness of the optical film layer is preferably 20-80 μm. The total thickness of the holographic film 42 is less than or equal to 50 mm. After the holographic film 42 is attached to the waveguide layer 41, the total thickness of the waveguide layer 41 and the holographic film 42 is less than 0.1 mm.

[0046] In some embodiments, liquid crystal materials can be used instead of photopolymers. The refractive index of the liquid crystal material is modulated to 0.3, thereby increasing the diffraction efficiency by 3 times and significantly improving light leakage utilization and the diffraction efficiency of the holographic grating. In some embodiments, flexible COP materials can be used instead of rigid glass. Flexible COPs have higher bending resistance... The 1000R value gives the holographic film 42 better flexibility. Furthermore, the waveguide layer 41 and the holographic film 42 can be cut or trimmed into any suitable shape and size according to actual needs.

[0047] In some embodiments, engineers can use different exposure wavelengths (i.e., use light of different colors) to expose the film and obtain a multi-color holographic film layer, such as an RGB three-color holographic film layer (i.e., a red holographic film layer, a green holographic film layer, and a blue holographic film layer). The multi-color holographic film layers are stacked together, and each holographic film responds to a specific leakage wavelength, thereby realizing a colorful, static, preset pattern diffraction display.

[0048] The holographic film 42 of this embodiment is compatible with diffraction waveguides such as SRG / VHG / PVG, utilizing the inherent light leakage of the waveguide in the waveguide layer 41 (where SRG forward light leakage is also present). PVG light leakage As an activation light source, the static mark pre-placed within the holographic film 42 is displayed in a preset area of ​​the lens. Here, SRG waveguide refers to a surface relief grating waveguide, VHG waveguide is a volume holography grating waveguide, and PVG waveguide is a polarization volume grating waveguide.

[0049] The reticle is an optical element with a reticle pattern (in this embodiment, the reticle pattern is the pattern to be displayed). It is placed at a specific position in the imaging system. When the object light rays after being split pass through the reticle, the pattern in the reticle is focused by the objective lens and imaged onto the hologram.

[0050] Please refer to the following: Figure 7a and Figure 7b In some embodiments, the waveguide layer 41 includes a waveguide sheet 411 and a first protective sheet 412, wherein the first protective sheet 412 is attached to a first side of the holographic film 42, and the waveguide sheet 411 is attached to a second side of the holographic film 42. The first protective sheet 412 is used to protect the waveguide sheet 411 and the holographic film 42 to reduce or avoid friction damage to the waveguide sheet 411 and the holographic film 42.

[0051] Please see Figure 7c More specifically, the first protective sheet 412 is attached to the first side of the protective film 422 (i.e., the first side of the holographic film 42), the second side of the protective film 422 is attached to the first side of the holographic sheet 421, and the waveguide sheet 411 is attached to the second side of the holographic sheet 421 (i.e., the second side of the holographic film 42).

[0052] Please refer to the following: Figure 8a and Figure 8b In some embodiments, the waveguide layer 41 includes a first waveguide sheet 41a, a second waveguide sheet 41b, and a second protective sheet 41c. The first waveguide sheet 41a is attached to a first side of the holographic film 42, the second waveguide sheet 41b is attached to a second side of the holographic film 42, and the second protective sheet 41c is attached to a first side of the first waveguide sheet 41a. The first side of the first waveguide sheet 41a is the side away from the holographic film 42.

[0053] Please see Figure 8c More specifically, the second protective sheet 41c is attached to the first side of the first waveguide sheet 41a, the second side of the first waveguide sheet 41a is attached to the first side of the protective film 422 (i.e., the first side of the holographic film 42), the second side of the protective film 422 is attached to the first side of the holographic sheet 421, and the second waveguide sheet 41b is attached to the second side of the holographic sheet 421 (i.e., the second side of the holographic film 42).

[0054] It is understood that the smart glasses provided by this utility model pre-set the static sign to be displayed in the holographic film, attach the holographic film to the waveguide layer, and utilize the light leakage characteristics of the waveguide layer to design the waveguide layer as an activation light source, so as to present the static sign pre-set in the holographic film in the preset area of ​​the lens. Thus, the light of the light source combined with the light leakage characteristics of the waveguide realizes the presentation of the static sign. There is no need to set up an additional display module / projection module, saving costs and energy consumption, increasing the battery life of the smart glasses, not occupying the space around the optical waveguide, and improving the freedom of optical design of the smart glasses.

[0055] Please refer to the following: Figure 9a , Figure 9b and Figure 9c In some embodiments, the smart glasses 100 further includes a nose pad assembly 60, which includes a nose pad bracket 61, a first nose pad 62, and a second nose pad 63. The nose pad bracket 61 is disposed on the main frame 21, specifically, the nose pad bracket 61 is disposed in the fixing groove 2142 of the main connecting part 214 in the main frame 21. The first end of the nose pad bracket 61 is connected and fixed to the first nose pad 62, and the second end of the nose pad bracket 61 is connected and fixed to the second nose pad 63.

[0056] In this embodiment, by setting the nose pad assembly 60 to cooperate with the temples 10, the user can wear the smart glasses 100 on their head, providing the user with a better user experience and meeting the user's needs.

[0057] Please see Figure 9a or Figure 9b In some embodiments, there are two temples 10, each temple 10 including a first housing 13 and a second housing 14, wherein the second housing 14 is nested and fixed to the first housing 13. In this embodiment, the smart glasses 100 also includes a battery 70, which is disposed within the space formed by the first housing 13 and the second housing 14 of one of the two temples 10 and fixed to the first housing 13. There are two light sources 30, and the battery 70 is electrically connected to the two light sources 30 respectively to provide power to the light sources 30. It can be understood that, in order to enable the battery 70 to provide power to the light sources 30, the smart glasses 100 also includes a power supply circuit, which is electrically connected between the battery 70 and the two light sources 30. It is readily understood that the power supply circuit can be any suitable type of circuit, component, or module, etc., and this embodiment of the present invention does not limit it in any way.

[0058] In this embodiment, by making full use of the space in the temple 10 and placing the battery 70 in the temple 10, it is possible to provide power to the light source 30, and significantly improve the compactness of the smart glasses 100, reducing its weight and volume.

[0059] Please see Figure 9a or Figure 9b In some embodiments, the temple 10 is provided with a charging interface 11 and a power switch 12, and the battery 70 is electrically connected to both the charging interface 11 and the power switch 12. When the charging interface 11 is electrically connected to an external power supply, the external power supply provides power to the battery 70 through the charging interface 11. The power switch 12 controls the battery 70 to turn on or off. When the power switch 12 is pressed, it receives a control signal and starts or stops the operation of the battery 70, so that the battery 70 provides power to the light source 30. Similarly, a power supply circuit is provided between the battery 70 and the charging interface 11 and the power switch 12. The power supply circuit enables the electrical connection between the battery 70 and the charging interface 11 and the power switch 12, thereby providing power to the battery and starting or stopping the battery 70.

[0060] In this embodiment, by providing a charging interface 11 and a power switch 12, the battery 70 can be conveniently charged, and the start-up or shutdown of the battery 70 can be quickly and conveniently controlled.

[0061] Please refer to the following: Figure 10 as well as Figure 11 In some embodiments, the smart glasses 100 further includes a camera component 80. The main frame 21 includes a main connecting portion 214 with a mounting groove 2141. The fixed frame 22 includes a connecting portion 223 with a light-transmitting opening 2231 at a position corresponding to the mounting groove 2141. The dimensions of the camera component 80, the mounting groove 2141, and the light-transmitting opening 2231 are matched, i.e., the dimensions of the camera component 80, the mounting groove 2141, and the light-transmitting opening 2231 are the same or similar. The camera component 80 is mounted in the mounting groove 2141, and the light-transmitting opening 2231 allows external light to pass through to the camera component 80, enabling it to receive light and capture video or images. For example, after the lens 40 is fixed to the frame 20, the light-transmitting opening 2231 is aligned with the mounting groove 2141, thereby fixing the camera component 80 to the main frame 21.

[0062] In summary, the smart glasses provided by this utility model pre-set the static sign to be displayed within a holographic film, attach the holographic film to the waveguide layer, and utilize the light leakage characteristics of the waveguide layer. The waveguide layer is designed as an activation light source, and the static sign pre-set within the holographic film is displayed in a preset area of ​​the lens. Thus, the light from the light source, combined with the light leakage characteristics of the waveguide, is used to display the static sign. There is no need to set up an additional display module / projection module, saving costs and energy consumption, increasing the battery life of the smart glasses, and not occupying the space around the optical waveguide, thereby improving the freedom of optical design of the smart glasses.
