Description

[0001] This application belongs to the field of smart wearable device technology, specifically relating to a smart pair of glasses. Background Technology

[0002] A normal person's eyes can see objects clearly from far to near, mainly by relying on the ciliary muscle to adjust the curvature of the lens surface. When the curvature of the lens surface changes, the light entering the eye from the outside will also change accordingly. When the focal point of the image falls exactly on the retinal area at the bottom of the eye, the object can be seen clearly; otherwise, it will not be seen clearly, which manifests as myopia or presbyopia.

[0003] In existing technology, in order to see objects at normal distances, people usually wear nearsighted glasses and reading glasses. However, because ordinary glasses cannot zoom, their range of application is limited, which means that users can only see objects within a specific distance range and need to replace their glasses regularly according to changes in their prescription.

[0023] The following is combined with Figures 1-26 This application describes smart glasses according to embodiments thereof.

[0024] like Figures 1 to 2 As shown, according to a first aspect of this application, a smart glasses is provided, including a lens body 1, a lens module 2, and a control module 3; the lens module 2 includes an elastic component 24, a fixing bracket 21, and a lens, the fixing bracket 21 is mounted on the lens body 1, and the periphery of the lens is mounted on the fixing bracket 21; the elastic component 24 includes a transparent elastic sheet 241 and a transparent piezoelectric sheet 242 integrally bonded together, the elastic component 24 is stacked on one side of the lens, and its periphery is mounted on the fixing bracket 21; the control module 3 controls the electric field applied to the piezoelectric sheet 242, so that the elastic component 24 can deform in the thickness direction of the lens module 2 to adjust the focal length of the lens module 2.

[0025] Specifically, in this embodiment, the smart glasses mainly consist of a lens body 1, a lens module 2, and a control module 3. The periphery of the elastic component 24 and the lens is mounted on a fixed bracket 21. The fixed bracket 21 is mounted on the lens body 1 to provide a mounting base for the whole and to ensure the stability of the optical body. The lens can be set with one, two, or more convex or concave lenses according to actual needs. The elastic component 24 can also be set with one, two, or more as needed. At the same time, the piezoelectric sheet 242 can be set with one piece attached to one side of the elastic component, or two pieces attached to both sides of the elastic sheet 241. There is no limitation on this.

[0026] The elastic component 24 is an integral structure formed by bonding a transparent elastic sheet 241 and a transparent piezoelectric sheet 242 together, and is stacked on one side of the lens to achieve coaxial cooperation with the lens. The elastic component 24 can be stacked on one side of the lens without any connection, or it can be attached to the lens surface using adhesive or similar methods. (See reference...) Figures 14 to 16 .like Figure 17The image shows the initial state of the lens module 2, consisting of a single-layer lens and a single elastic component 24. When the periphery of the piezoelectric sheet 242 is fixed, leaving only the central portion as a free region, applying different electric fields to its front and back surfaces via the control module 3 will cause the piezoelectric sheet 242 to bulge to a desired height. The height of the bulge is controlled by the magnitude of the electric field, and different curvatures of the elastic body correspond to different final focal lengths of the eyeglasses. Figure 18 and Figure 19 As shown.

[0027] The smart glasses provided in this application have a compact overall structure. Each component is positioned and assembled using a fixed bracket 21, integrating piezoelectric drive, elastic deformation, and optical lenses into the same module, providing stable structural support and a mounting foundation for focus adjustment. The elastic element can be made of materials such as TPU, TPE, TPR, silicone, or POE, while the piezoelectric sheet 242 is made of transparent piezoelectric ceramic material.

[0028] In practical applications, control module 3 changes the electric field applied to the transparent piezoelectric sheet 242, causing the piezoelectric sheet 242 to deform accordingly. Since the transparent elastic sheet 241 and the piezoelectric sheet 242 are bonded together, the deformation of the piezoelectric sheet 242 will cause the elastic component 24 to undergo controllable deformation in the thickness direction of the lens module 2. The deformation of the elastic component 24 directly changes the overall optical thickness and refractive index distribution of the lens module 2, thereby changing the refraction path and converging ability of light after passing through the lens module 2, ultimately achieving continuous adjustment of the imaging focal length. (Refer to...) Figure 26 L represents the refraction angle, and Y represents the intraocular focal length adjusted by lens module 2. It can be seen that adjusting the focal length of lens module 2 allows the image focus of an object to fall on the retina of the human eye 5, enabling the user to see the object clearly. The entire process uses electrical signals as control input, piezoelectric actuation as the execution method, and elastic deformation to change optical parameters, thus achieving active focal length adjustment.

[0029] Compared to traditional fixed-prescription glasses, these smart glasses offer active focus adjustment, overcoming the limitations of ordinary glasses that cannot zoom and have a limited range of applicable distances. Users can adapt to different viewing distances without changing their glasses, effectively improving the user experience for people with refractive errors such as myopia and presbyopia. The control module 3 can adjust the electric field in real time to change the focus, adapting to the user's needs in different scenarios and at different viewing distances, eliminating the hassle of regularly changing glasses. Furthermore, by combining transparent piezoelectric elements with elastic components 24, miniaturization and electronic adjustment are achieved while ensuring a clear optical path, enhancing the glasses' intelligence and ease of use, resulting in a wider range of applications and greater flexibility.

[0030] Optionally, such as Figures 4 to 6As shown, the elastic component 24 includes two piezoelectric sheets 242, which are respectively attached to the two surfaces of the elastic sheet 241 and electrically connected to the control module 3.

[0031] Specifically, in this embodiment, by configuring the elastic component 24 as two piezoelectric sheets 242 respectively attached to the two surfaces of the elastic sheet 241, the technical effect of focal length adjustment of the smart glasses lens module 2 can be significantly improved. The two piezoelectric sheets 242 are electrically connected to the control module 3 respectively, and can be driven synchronously or collaboratively under the action of an electric field to form bidirectional driving and stable clamping of the elastic sheet 241, greatly improving the controllability and response accuracy of deformation.

[0032] Compared to single-sided piezoelectric element 242 driving, the dual-sided arrangement can produce a larger amplitude and more uniform deformation under the same voltage, enhancing the adjustment range of the refractive index and focal length of the lens module 2. It also improves driving stability and structural symmetry, reduces optical distortion, and ensures clear imaging. This structure strengthens driving capability and optimizes adjustment effect, making smart glasses more sensitive and reliable when switching between near and far vision, and applicable to a wider range of scenarios.

[0033] Optionally, such as Figures 7 to 9 As shown, the lens module 2 includes multiple lenses, which include at least an inner lens 22 and an outer lens 23. The multiple lenses are spaced apart from each other along the thickness direction and are sequentially assembled on the fixed bracket 21. The inner lens 22 is located on the side closer to the human eye 5, and the outer lens 23 is located on the side farther away from the human eye 5. The elastic component 24 is located between any two adjacent lenses.

[0034] Specifically, in this embodiment, the lens module 2 adopts a multi-lens combination structure, including at least an inner lens 22 closer to the human eye 5 and an outer lens 23 farther from the human eye 5. The multiple lenses are spaced apart from each other along the thickness direction and are sequentially mounted on the fixed bracket 21. The elastic component 24 is disposed between any two adjacent lenses. This multi-layer optical structure can significantly improve the optical performance and zoom capability of smart glasses. Through the synergistic effect of multiple lenses, the light refraction path is optimized, the image quality is improved, optical defects such as aberrations and distortions are reduced, and clear and stable vision is ensured for both near and far objects.

[0035] Placing the elastic component 24 between the two lenses allows the deformation drive to act more directly and efficiently on the optical system, making focus adjustment more sensitive and precise. It also improves the overall structural symmetry and stability, reducing drive losses. The multi-layered, spaced layout provides reasonable space for the deformation of the elastic component 24 and expands the focus adjustment range through multi-lens combinations, enhancing its adaptability to different refractive states and viewing distances. This results in significant improvements in zoom range, adjustment accuracy, and imaging effect for smart glasses, better meeting the diverse visual needs of people with myopia, presbyopia, and other conditions, eliminating the need for frequent glasses changes, and improving user comfort and the breadth of applicable scenarios.

[0036] In one embodiment, such as Figures 20 to 22 As shown, the lens module 2 includes an inner lens 22, an outer lens 23, and an elastic component 24 spaced between the inner lens 22 and the outer lens 23. The elastic component 24 includes an elastic sheet 241 and piezoelectric sheets 242 attached to the two surfaces of the elastic sheet 241, allowing both sides of the elastic sheet 241 to deform simultaneously. The outer lens 23, located on the outer side of the elastic component 24, is made of a non-deformable hard material and serves to protect the elastomer located inside it. The inner lens 22, located on the inner side of the elastic component 24, is also made of a non-deformable hard material and serves the same function as the outer lens 23. Except for the periphery, the middle part of the elastic component 24 is in a free state, and the movement of the piezoelectric sheets 242 on both sides can move the surface of the elastic sheet 241 together. The deformation arc and direction of the transparent piezoelectric sheets 242 on both sides of the elastic sheet 241 can be controlled separately as needed, resulting in different arc sizes and directions of the entire elastomer. Different arcs of the elastic sheet 241 correspond to different final eyeglass focal lengths. Figure 23 This is the initial state of lens module 2, and Figure 24 This is a schematic diagram showing both piezoelectric plates 242 deforming away from the elastic plate 241. Figure 25 This is a schematic diagram showing that both piezoelectric pieces 242 deform towards the side closer to the inner lens 22. It can be seen that the user can adjust the direction and size of the deformation of the elastic component 24 according to actual needs, thereby achieving the purpose of adapting to different focal length requirements.

[0037] Optionally, refer to Figures 7 to 9 As shown, multiple elastic components 24 are provided, and the multiple elastic components 24 are arranged sequentially and spaced apart between the inner lens 22 and the outer lens 23 along the thickness direction.

[0038] Specifically, in this embodiment, by sequentially arranging multiple elastic components 24 at intervals along the thickness direction between the inner lens 22 and the outer lens 23, the zoom performance and adjustment accuracy of the smart glasses lens module 2 can be significantly improved. The multiple elastic components 24 work synchronously or collaboratively, enabling a wider focal length adjustment range under the same driving voltage, enhancing adaptability to different viewing distances and refractive powers, and further expanding the clear viewing range.

[0039] The multiple sets of elastic components 24 are arranged at intervals, which makes the overall deformation of the lens module 2 uniform and controllable. This effectively reduces problems such as uneven deformation and optical distortion that may occur when a single elastic component 24 is driven, thus improving image clarity and stability. At the same time, the superimposed driving of multiple components can improve the adjustment response speed and control precision, enabling fine and continuous adjustment of the focal length. This better meets the needs of vision in multiple scenarios, including far, medium and near vision. Without significantly increasing structural complexity, it greatly enhances zoom capability and optical performance, improving the intelligence and practicality of the glasses.

[0040] Optionally, such as Figures 7 to 9 As shown, the fixed bracket 21 is a ring structure, and the inner ring of the ring structure is provided with an assembly groove 211. The lens and the elastic component 24 are respectively fixedly assembled in the assembly groove 211.

[0041] Specifically, in this embodiment, the fixing bracket 21 is a ring structure with an assembly groove 211 in the inner ring. The lens and the elastic component 24 are fixedly assembled within the assembly groove 211, effectively improving the structural stability and assembly accuracy of the lens module 2. The ring bracket provides uniform and symmetrical circumferential constraints on the lens and the elastic component 24, avoiding deformation shifts and optical center misalignment caused by unstable edge fixing, thus ensuring optical path stability during zooming. The assembly groove 211 provides uniform and precise installation positioning for each optical component, simplifying the assembly process, improving assembly efficiency and consistency, and reducing production errors. Simultaneously, the peripheral embedded fixing reduces interference with the central optical area, ensuring the integrity of the light-transmitting area and clear imaging, improving the reliability and repeatability of focus adjustment, and enabling the smart glasses to maintain stable zoom performance and image quality during long-term use.

[0042] Optionally, such as Figures 10 to 12 As shown, the periphery of the lens and the elastic component 24 are respectively fixed in the assembly groove 211 by the sealing ring 25.

[0043] Specifically, in this embodiment, the peripheries of the lens and the elastic component 24 are respectively fixed in the assembly groove 211 of the fixing bracket 21 by sealing rings 25, which can significantly improve the sealing performance, structural stability, and optical reliability of the lens module 2. The sealing rings 25 can form a flexible and uniform circumferential compression fixation for the lens and the elastic component 24, avoiding component stress, deformation, or damage caused by rigid assembly, and ensuring that the position of each optical element is stable and the optical path center does not shift during the zooming process. At the same time, the sealing rings 25 can effectively prevent external impurities such as dust and moisture from entering between the lens and the elastic component 24, maintaining the cleanliness of the optical interface, reducing problems such as image blurring and decreased light transmittance, and extending the service life of the smart glasses.

[0044] In addition, the sealing ring 25 also serves as a buffer and vibration damper, improving the overall structural durability and ensuring that the lens module 2 maintains stable adjustment accuracy and image quality during long-term zoom use, thereby enhancing the product's environmental adaptability and reliability. In some embodiments, the spacing between the lenses and elastic components 24 is achieved through the sealing ring 25 to simplify assembly.

[0045] Optionally, such as Figures 10 to 12As shown, the control module 3 includes a circuit board 31 and an electrical connector 32; a wiring hole 212 is provided on the bottom wall of the assembly groove 211 corresponding to the position of the piezoelectric sheet 242, and the electrical connector 32 passes through the wiring hole 212 to connect the piezoelectric sheet 242 and the circuit board 31.

[0046] Specifically, in this embodiment, the control module 3 includes a circuit board 31 and an electrical connector 32. A wiring hole 212 is formed on the bottom wall of the assembly slot 211 corresponding to the position of the piezoelectric piece 242. The electrical connector 32 passes through the wiring hole 212 to achieve electrical connection between the piezoelectric piece 242 and the circuit board 31. This structure integrates the control module 3 and the lens module 2, enabling concealed wiring and avoiding risks such as tangling, wear, and short circuits caused by exposed wires, thus improving the safety and structural reliability of the smart glasses. The precise positioning of the wiring hole 212 ensures stable connection between the electrical connector 32 and the piezoelectric piece 242, improving the accuracy and response speed of electrical signal transmission and ensuring timely and reliable electric field control. The internal wiring simplifies the overall structure, making the appearance more concise and neat, while not occupying the central optical area of ​​the lens, thus not affecting light transmission and imaging effects, ensuring stable and efficient focus adjustment, and improving product integration and practicality.

[0047] Optionally, such as Figure 3 and Figure 10 As shown, the smart glasses also include a detection module 4, which is used to detect the position parameters of external objects. The control module 3 can control the magnitude and direction of the electric field of the piezoelectric sheet 242 according to the position parameters.

[0048] Specifically, in this embodiment, the detection module 4 is used to detect the position parameters of external objects in real time, and the control module 3 can automatically adjust the magnitude and direction of the electric field applied to the piezoelectric sheet 242 based on these parameters. Through the linkage between the detection module 4 and the control module 3, the focus adjustment is automated and intelligent, and the optimal focus can be quickly matched according to the viewing distance without manual operation by the user.

[0049] This feature significantly improves zoom response speed and adjustment accuracy, ensuring the image focus falls quickly and precisely on the retina, guaranteeing clear imaging of objects at varying distances and effectively enhancing user convenience and comfort. Simultaneously, closed-loop automatic control avoids errors and delays caused by manual adjustments, broadening the applicable scenarios for the glasses and better adapting to the needs of users with different refractive conditions such as myopia and presbyopia, significantly enhancing the intelligence level and actual user experience of smart glasses.

[0050] In the above structure, the detection module 4 can be an infrared ranging module, a laser ranging module, a visual camera module, or an ultrasonic ranging module, depending on the actual needs.

[0051] Optionally, such as Figure 1 , Figure 2 , Figure 10 , Figure 13 , Figure 14 and Figure 20 As shown, there are two sets of lens modules 2, which are respectively mounted on the lens body 1. The control module 3 can adjust the focal length of the two sets of lens modules 2 respectively.

[0052] Specifically, in this embodiment, the lens module 2 is configured as two sets, corresponding to the left and right eyes respectively and independently mounted on the lens body 1. The control module 3 can independently adjust the focal length of the two lens modules 2. This structure can meet the personalized needs of users with different refractive powers in their left and right eyes, achieving precise adaptation for each eye and avoiding visual discomfort, dizziness, or visual fatigue caused by differences in power. Independent adjustment allows the focal point of both eyes to simultaneously and accurately fall on the retina, improving binocular visual coordination and stereoscopic vision. At the same time, the focal length of one side can be adjusted separately according to different usage scenarios, making it more flexible and significantly improving the adaptability and wearing comfort of the smart glasses, enhancing practicality and versatility.

[0053] Optionally, such as Figure 2 and Figure 13 As shown, the mirror body 1 includes a front shell 11 and a rear shell 12, and a receiving cavity is formed between the front shell 11 and the rear shell 12. The control module 3 is assembled in the receiving cavity.

[0054] Specifically, in this embodiment, the lens body 1 adopts a combined structure of a front shell 11 and a rear shell 12, forming a receiving cavity between them, and the control module 3 is assembled inside this receiving cavity. This built-in installation effectively protects the control module 3 from damage caused by dust, moisture, and external impacts, improving structural reliability and service life. The receiving cavity achieves integrated design of the control module 3 with the external structure, making the lens body 1 more aesthetically pleasing and not affecting wearing comfort. Simultaneously, the built-in layout optimizes overall weight distribution, reduces exposed components, improves the safety and structural stability of the glasses, and provides a stable and enclosed working environment for the circuitry and drive module, ensuring reliable operation of focus control.
