Description

[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.

[0023] The following is combined with Figures 1-23 This application describes smart glasses according to embodiments thereof.

[0024] like Figures 1 to 23 As shown, according to some embodiments of this application, a smart glasses is provided, including: a lens body 1, a lens assembly 2, an adjustment assembly 3, and a control module 4; the lens assembly 2 includes a fixed bracket 21 and a lens module 22, the fixed bracket 21 is mounted on the lens body 1, and the lens module 22 is movably mounted on the fixed bracket 21 along a first direction, the first direction being the thickness direction of the lens module 22; the lens module 22 includes at least two lenses, the at least two lenses being sequentially spaced and movably mounted on the fixed bracket 21 respectively; the adjustment assembly 3 is mounted on the lens assembly 2; the control module 4 is connected to the adjustment assembly 3 and can control the position of the lens module 22 and / or at least one lens relative to the fixed bracket 21 in the first direction through the adjustment assembly 3, so as to adjust the focal length of the lens module 22.

[0025] Specifically, in this embodiment, the smart glasses are mainly composed of a lens body 1, a lens assembly 2, an adjustment assembly 3, and a control module 4, forming an optical system with dynamically adjustable focal length. The lens assembly 2, as the core structure, includes a fixed bracket 21 and a lens module 22. The fixed bracket 21 is mounted on the lens body 1, providing a mounting base and motion reference for the optical components. The lens module 22, with its thickness defined as a first direction, is movably mounted on the fixed bracket 21. The lens module 22 consists of at least two lenses, arranged sequentially at intervals, and each lens is movably mounted on the fixed bracket 21, providing a structural basis for focal length adjustment.

[0026] In the above structure, the adjustment component 3 is mounted on the lens component 2 and works in conjunction with the lens module 22. The control module 4 is electrically or driven to the adjustment component 3. The overall structure is compact and rationally laid out. It retains the wearing form of traditional glasses and integrates a movable optical adjustment mechanism, providing stable and reliable structural support for achieving dynamic zoom.

[0027] The control module 4 and adjustment component 3 provided in this application can cooperate with the lens assembly 2 in various ways, such as motor-driven adjustment, electromagnetic-driven adjustment, and piezoelectric-driven adjustment. In motor-driven adjustment, the control module 4 outputs commands to drive a micro-motor, which, through a transmission structure such as gears, lead screws, or belts, converts the rotational motion into linear displacement, pushing the entire lens module 22 or a single lens within it to move along a first direction, changing the lens spacing and relative position. In electromagnetic-driven adjustment, electromagnetic elements are respectively set on the lens and the fixed bracket 21. The control module 4 generates controllable electromagnetic force by changing the magnitude and direction of the current, directly driving the lens to translate along the thickness direction, resulting in fast response and a simple structure. Furthermore, in piezoelectric-driven adjustment, the micro-displacement characteristics of piezoelectric materials after being energized are utilized. The control module 4 applies corresponding electrical signals to cause the piezoelectric elements to precisely move the lens, resulting in high positioning accuracy and smooth movement. All of the above methods are uniformly controlled by the control module 4, which drives the lens module 22 to move through the adjustment component 3, thereby achieving the purpose of changing the focal length of the lens module 22.

[0028] The smart glasses provided in this application, through a dynamically adjustable focal length structure design, significantly improve the user experience and visual adaptation capabilities, overcoming the inherent defects of traditional fixed-prescription glasses. Compared to ordinary nearsighted glasses and reading glasses with non-adjustable lenses, this application can adjust the lens focal length in real time through the control module 4 and the adjustment component 3, so that external light is accurately focused on the user's retina after passing through the lens, thereby clearly seeing objects at different distances and greatly expanding the range of clear vision. (Reference) Figure 23 Users no longer need to change multiple pairs of glasses for different viewing distances, nor do they need to frequently re-fit glasses due to changes in prescription, effectively reducing usage costs and replacement hassles. The overall technical solution has a simple structure and reliable adjustment, and can adapt to people with different vision conditions such as myopia and presbyopia, improving the versatility, comfort, and practicality of smart glasses.

[0029] In the above embodiments, the lens module 22 adopts a multi-layered movable structure, which, together with precise adjustment and control, can ensure clear imaging and small optical distortion. While realizing the zoom function, it maintains a good visual effect. Each lens can be selected as a convex lens, concave lens, or flat lens according to actual needs, and there are no restrictions here.

[0030] Optionally, such as Figures 2 to 16 As shown, the adjustment component 3 includes a first magnetic component 31 and a second magnetic component 32; the first magnetic component 31 and the second magnetic component 32 are respectively disposed on the fixed bracket 21 and the lens module 22, and the first magnetic component 31 and / or the second magnetic component 32 are electromagnet components; the control module 4 is electrically connected to the electromagnet components and can adjust the focal length of the lens component 2 by controlling the magnetism of the first magnetic component 31 and / or the second magnetic component 32.

[0031] Specifically, in this embodiment, the adjustment component 3 adjusts the focal length of the lens module 22 primarily through electromagnetic drive. The adjustment component 3 mainly consists of a first magnetic component 31 and a second magnetic component 32, which are correspondingly mounted on the fixed bracket 21 and the lens module 22 to form a magnetic attraction relationship. Furthermore, either the first magnetic component 31 or the second magnetic component 32 is an electromagnet, or both are electromagnets; that is, at least one set is an electrically controllable electromagnetic structure. This allows the control module 4 to be electrically connected to the electromagnet components, thereby enabling the overall position adjustment of the lens module 22 or the position adjustment of at least one lens through magnetic attraction. This provides a stable and reliable structural foundation for the electronically controlled adjustment of the focal length of the lens module 22, meeting the design requirements of lightweight and miniaturized smart glasses.

[0032] In the above structure, the adjustment component 3 adopts a magnetic drive method. The control module 4 controls the on / off state, current magnitude, and magnetic field direction of the electromagnet component through electrical signals, thereby changing the magnitude and direction of the attraction or repulsion force between the first magnetic component 31 and the second magnetic component 32. Under the drive of electromagnetic force, the lens module 22 can be displaced relative to the fixed bracket 21 along the first direction, thereby adjusting the lens spacing or the distance between the lens module 22 and the human eye 6, realizing the adjustment of the overall optical focal length of the lens module 22, so that the light is accurately focused on the retina, achieving clear imaging of objects at different distances. The number of magnets contained in the first magnetic component 31 and the second magnetic component 32 can be set according to actual needs.

[0033] Compared to traditional mechanical transmission structures, this electromagnetic adjustment method offers advantages such as fast response, smooth movement, no mechanical wear, and low noise. It can improve focus adjustment accuracy and operational stability, and extend the lifespan of smart glasses. Specifically, the first magnetic component 31 can be assembled by setting a first positioning groove 214 on the fixed bracket 21, while the second magnetic component 32 can be assembled by setting a second positioning groove 223 on the lens. The specific quantities can be matched according to the number of magnetic elements contained in each magnetic component.

[0034] Optionally, such as Figures 2 to 13As shown, the fixing bracket 21 is configured as an annular structure, and the inner ring of the annular structure is provided with an annular groove 213. The annular groove 213 has a first sidewall 211 and a second sidewall 212. The lens module 22 includes at least an inner lens 221 assembled near the first sidewall 211 and an outer lens 222 assembled near the second sidewall 212. The first magnetic component 31 includes a plurality of first magnetic elements 311, which are spaced apart around the annular groove 213 on the first sidewall 211. The second magnetic component 32 includes a plurality of second magnetic elements 321, which are spaced apart on the periphery of the inner lens 221 and are respectively arranged in correspondence with the plurality of first magnetic elements 311.

[0035] Specifically, in this embodiment, the technical solution uses an annular fixing bracket 21 and an annular groove 213 structure to provide stable assembly and motion guidance for the inner lens 221 and the outer lens 222, so that the two lenses are arranged close to the first sidewall 211 and the second sidewall 212 respectively, forming a layered assembly structure, which helps to ensure the coaxiality of the lenses and the alignment of the optical center. Multiple first magnetic elements 311 are arranged circumferentially on the first sidewall 211 along the annular groove 213, corresponding one-to-one with the second magnetic elements 321 on the periphery of the inner lens 221, which can achieve uniform circumferential force driving.

[0036] Under the action of electromagnetic force, the inner lens 221 can move smoothly along the thickness direction, avoiding tilting, offset, or jamming caused by unilateral force, thus improving the lens movement accuracy and focusing stability. This structure eliminates the need for complex transmission components, is compact and reliable, and enables fast, precise, and low-noise focus adjustment. It effectively improves the imaging clarity of smart glasses when switching between near and far distances, while reducing mechanical wear, extending product lifespan, and meeting the needs for lightweight and miniaturized wear.

[0037] Optionally, such as Figures 2 to 13 As shown, the fixed bracket 21 is configured as an annular structure, and the inner ring of the annular structure is provided with an annular groove 213. The annular groove 213 has a first sidewall 211 and a second sidewall 212. The lens module 22 includes at least an inner lens 221 assembled near the first sidewall 211 and an outer lens 222 assembled near the second sidewall 212. The first magnetic component 31 includes a plurality of third magnetic elements 312, which are spaced apart around the annular groove 213 on the second sidewall 212. The second magnetic component 32 includes a plurality of fourth magnetic elements 322, which are spaced apart on the periphery of the outer lens 222 and are respectively corresponding to the plurality of third magnetic elements 312.

[0038] Specifically, in this embodiment, based on the structure of the annular fixed bracket 21 and the annular groove 213, the inner lens 221 and the outer lens 222 are limited and positioned using the first sidewall 211 and the second sidewall 212, ensuring the overall structural stability and optical path reliability of the lens module 22. Multiple third magnetic components 312 are evenly arranged circumferentially along the second sidewall 212, corresponding one-to-one with the fourth magnetic components 322 on the periphery of the outer lens 222, forming a symmetrical and balanced electromagnetic drive structure. By controlling the magnitude and direction of the electromagnetic force, the outer lens 222 can be driven to move precisely along the first direction, and the position of the outer lens 222 can be independently adjusted to change the overall focal length of the lens group, achieving automatic focusing for near and far objects. The circumferential multi-point magnetic attraction ensures that the outer lens 222 is subjected to uniform force and moves smoothly, effectively reducing shaking, eccentricity, and frictional resistance, and improving the adjustment response speed and control accuracy.

[0039] The structure provided in this application is simple and easy to assemble, and can achieve reliable zoom without increasing the overall size, thereby improving image quality and user comfort and adapting to the dynamic visual needs of people with different vision.

[0040] In some embodiments, combining the two schemes of independently driving the inner lens 221 and the outer lens 222 allows for bidirectional, independent, and precise adjustment of the inner and outer lenses 222, significantly expanding the focal length adjustment range and accuracy. Driven by their respective circumferentially evenly distributed magnetic components, both the inner lens 221 and the outer lens 222 maintain balanced force and smooth movement, effectively avoiding eccentricity, tilting, and jamming, further enhancing the stability of the optical system. By independently controlling the relative positions of the two lenses, more precise and flexible focal length adjustment can be achieved, adapting to a wider range of myopia, presbyopia, and mixed vision problems. The overall structure is compact and highly efficient, enabling continuous, smooth, and rapid automatic zoom, significantly improving the adaptability, image quality, and user experience of smart glasses.

[0041] Optionally, such as Figures 2 to 13 As shown, the lens assembly 2 also includes a first sealing ring 23, a second sealing ring 24 and at least one third sealing ring 25; the first sealing ring 23 is sandwiched between the first sidewall 211 and the inner lens 221, the second sealing ring 24 is sandwiched between the second sidewall 212 and the outer lens 222, and at least one third sealing ring 25 is sandwiched between the inner lens 221 and the outer lens 222.

[0042] Specifically, in this embodiment, by setting a first sealing ring 23, a second sealing ring 24, and at least one third sealing ring 25 in the lens assembly 2, the structural stability, optical reliability, and service life of the smart glasses are improved, and the smoothness of movement and environmental adaptability during zooming are effectively improved. The first sealing ring 23 is sandwiched between the first sidewall 211 and the inner lens 221, and the second sealing ring 24 is sandwiched between the second sidewall 212 and the outer lens 222. This forms a flexible buffer and sealed isolation between the lens and the fixed bracket 21, avoiding friction, noise, and wear caused by direct contact between metal or hard structures. It also reduces the entry of external dust, moisture, and other impurities into the annular groove 213, ensuring a clean and stable environment for lens movement.

[0043] Furthermore, the third sealing ring 25 is sandwiched between the inner lens 221 and the outer lens 222. It guides and dampens the relative movement of the two lenses, suppressing wobbling, tilting, and eccentricity during movement and maintaining optical center alignment. It also forms a sealed area between the two lenses, preventing foreign objects from entering and affecting focus adjustment accuracy. The combined use of multiple sealing rings achieves reliable sealing, dust and water resistance, while improving the smoothness and coaxiality of lens movement, reducing adjustment noise, and enhancing the durability and imaging stability of the optical system. This allows the smart glasses to maintain precise and smooth zoom function even in complex usage environments, extending the overall product lifespan.

[0044] In one embodiment, when the lens module 22 includes an inner lens, an outer lens, and a third or fourth lens, multiple third sealing rings 25 are correspondingly provided, respectively spaced between the inner lens 221 and the third lens, the fourth lens, and the outer lens 222. The inner lens 221 is the lens closest to the human eye 6 after the smart glasses are worn, while the outer lens 222 is the lens farthest from the human eye 6 after the smart glasses are worn.

[0045] Optionally, such as Figures 12 to 13 As shown, the first sealing ring 23 is provided with a plurality of first through holes 231 at intervals to connect the first magnetic element 311 and the corresponding second magnetic element 321; and / or, the second sealing ring 24 is provided with a plurality of second through holes 241 at intervals to connect the third magnetic element 312 and the corresponding fourth magnetic element 322.

[0046] Specifically, in this embodiment, by setting through-hole structures corresponding to the magnetic components on the sealing ring, the problem of the sealing structure blocking and attenuating the electromagnetic driving force is effectively solved while ensuring the functions of sealing, buffering, and dust prevention, thus achieving synergistic optimization of sealing performance and driving performance. Specifically, multiple first through-holes 231 are arranged at intervals on the first sealing ring 23, allowing a direct and stable magnetic circuit channel to be formed between the first magnetic component 311 on the first sidewall 211 and the second magnetic component 321 around the inner lens 221. This avoids the sealing ring material from shielding or weakening the magnetic field, ensuring stable and efficient transmission of electromagnetic force and improving the response speed and control accuracy of the lens drive. Similarly, multiple second through-holes 241 are provided on the second sealing ring 24, connecting the third magnetic component 312 on the second sidewall 212 and the fourth magnetic component 322 around the outer lens 222, maintaining a stable magnetic circuit and ensuring reliable adjustment of the outer lens 222.

[0047] The one-to-one correspondence and staggered arrangement of each through-hole and magnetic component preserves the overall sealing, dustproofing, buffering, and vibration damping functions of the sealing ring while maximizing the efficiency of the electromagnetic drive. This ensures uniform force and precise displacement of the lens during movement, avoiding insufficient driving force, adjustment lag, or inaccurate positioning caused by magnetic field loss. The overall structure is simple and easy to implement, improving environmental adaptability and structural reliability while ensuring the sensitivity, stability, and image quality of the smart glasses' zoom adjustment, achieving a balance between sealing protection and optical drive technology.

[0048] Optionally, such as Figure 2 ,as well as Figure 12 and Figure 13 As shown, a plurality of first magnetic elements 311 are uniformly disposed on the first sidewall 211, and a plurality of second magnetic elements 321 are uniformly disposed on the second sidewall 212; in the first direction, each third magnetic element 312 is disposed in a one-to-one correspondence with each first magnetic element 311, and each fourth magnetic element 322 is disposed in a one-to-one correspondence with each second magnetic element 321.

[0049] Specifically, in this embodiment, by uniformly arranging the first magnetic element 311 and the second magnetic element 321 on the first sidewall 211 and the second sidewall 212 respectively, and by arranging the third magnetic element 312 in a one-to-one correspondence with the first magnetic element 311 and the fourth magnetic element 322 in a one-to-one correspondence with the second magnetic element 321 in the first direction, a stable magnetic field structure with uniform circumferential distribution and axial symmetry can be formed. The uniformly arranged magnetic elements ensure that the lens is subjected to balanced forces during movement, avoiding tilting, shaking, eccentricity, or jamming due to uneven forces, and improving the smoothness and coaxiality of the lens movement.

[0050] In the above structure, the magnetic components arranged opposite each other along the first direction can form efficient and direct magnetic circuit coupling, enhancing magnetic field utilization and driving stability, reducing magnetic loss, and improving focusing response speed and adjustment accuracy. This arrangement is simple in structure and reasonable in layout, effectively improving the stability and imaging quality of the optical system while achieving reliable driving, and extending the service life of smart glasses.

[0051] Optionally, such as Figures 14 to 16 As shown, each of the first magnetic components 311 and each of the third magnetic components 312 are electromagnets and are electrically connected to the control module 4 respectively, and each of the second magnetic components 321 and each of the fourth magnetic components 322 are permanent magnets.

[0052] Specifically, in this embodiment, the first magnetic component 311 and the third magnetic component 312 are configured as electromagnets and electrically connected to the control module 4, while the second magnetic component 321 and the fourth magnetic component 322 are permanent magnets, enabling efficient, precise, and controllable electromagnetic drive of the lens module 22. The electromagnets are independently powered and regulated by the control module 4, allowing for flexible changes in magnetic field strength and direction. Together with the permanent magnets, they form a stable and controllable attractive or repulsive force, achieving precise adjustment of the lens displacement.

[0053] The aforementioned control method features clear logic and fast response, allowing for real-time adjustment of electromagnet parameters based on viewing distance to achieve dynamic focal length changes. Furthermore, the permanent magnet requires no power supply, resulting in a simple structure and high reliability. Its combination with the electromagnet reduces power consumption and simplifies circuit layout. The overall solution balances control flexibility and drive stability, ensuring smooth lens movement and precise positioning, thus improving the accuracy, response speed, and reliability of zoom adjustment in smart glasses.

[0054] Optionally, such as Figures 17 to 22 As shown, the control module 4 moves the lens module 22 along the first direction and / or moves at least one lens along the first direction by controlling the polarity and magnetic strength of the first magnetic element 311; and / or, the control module 4 moves the lens module 22 along the first direction and / or moves at least one lens along the first direction by controlling the polarity and magnetic strength of the third magnetic element 312.

[0055] Specifically, in this embodiment, the control module 4 independently or collaboratively controls the polarity and magnetic field strength of the first magnetic element 311 and the third magnetic element 312, which can flexibly drive the lens module 22 as a whole or individual lenses to move along the first direction, achieving fine and diversified adjustment of the focal length. By changing the polarity of the electromagnet, the control module 4 can switch the magnetic field to attraction or repulsion, thereby controlling the direction of lens movement; by adjusting the current to change the magnetic field strength, it can precisely control the lens movement speed and displacement, achieving continuous and smooth focal length changes.

[0056] like Figures 18 to 22As shown, the first magnetic component 311 and the third magnetic component 312 are both electromagnets and connected to the control module 4, while the second magnetic component 321 and the fourth magnetic component 322 are both permanent magnets. Figure 19 This displays the initial position of the lens module 22. When it's necessary to reduce the distance between the two lenses, repulsive forces can be simultaneously generated between the first magnetic components 311 and the second magnetic components 321, and between the third magnetic components 312 and the fourth magnetic components 322. Alternatively, one side can be de-energized (e.g., the first magnetic components 311 are not energized), while repulsive forces are generated on the other side (between the third magnetic components 312 and the fourth magnetic components 322). Figure 20 As shown; when it is necessary to increase the distance between the two lenses, attractive forces can be generated simultaneously between each of the first magnetic elements 311 and each of the second magnetic elements 321, and between each of the third magnetic elements 312 and each of the fourth magnetic elements 322, or one side can be de-energized (for example, each of the first magnetic elements 311 is not energized), while attractive forces are generated on the other side (between each of the third magnetic elements 312 and each of the fourth magnetic elements 322), such as... Figure 21 As shown, working on both sides simultaneously is more efficient; when it is necessary to move the entire lens module 22 away from the human eye 6, the electromagnet (first magnetic component 311) on the side closer to the human eye 6 can generate a repulsive force with the corresponding permanent magnet (second magnetic component 321), while the electromagnet (third magnetic component 312) on the side further away from the human eye 6 can generate an attractive force with the corresponding permanent magnet (fourth magnetic component 322). Alternatively, only one side can work. When it is necessary to move the lens module 22 closer to the human eye 6, the method can be reversed.

[0057] The aforementioned control method can drive the movement of a single lens individually or simultaneously drive multiple lenses for coordinated adjustment, significantly improving the zoom range and adaptability. The overall adjustment response is fast, the positioning accuracy is high, and the control is flexible, meeting the real-time focusing needs of different vision scenarios such as myopia and presbyopia, and significantly improving the user comfort and imaging stability of smart glasses.

[0058] Optionally, such as Figure 1 ,as well as Figures 14 to 16 As shown, the smart glasses also include a detection module 5, which is electrically connected to the control module 4. The detection module 5 is used to acquire the position parameters of external objects, and the control module 4 can control the magnetism of the first magnetic component 31 and / or the second magnetic component 32 according to the position parameters.

[0059] Specifically, in this embodiment, by adding a detection module 5 electrically connected to the control module 4, the focus of the smart glasses can be automatically, in real time, and adaptively adjusted, significantly improving ease of use and intelligence. The detection module 5 can acquire parameters such as the distance and position of external objects in real time and transmit the signals to the control module 4. The control module 4 automatically adjusts the magnetic field strength and polarity of the first magnetic component 31 and / or the second magnetic component 32 according to the distance of the object, driving the lens to move precisely so that the image focus is stably on the retina. Compared to manual adjustment, this method has a faster response and more accurate focus. Users can see objects at different distances without manual operation, effectively reducing visual fatigue and improving the wearing experience.

[0060] In the above embodiments, the detection module 5 can be implemented in various ways, such as an infrared ranging module, a laser ranging module, a visual image sensor, an ultrasonic ranging module, etc., all of which can achieve high-precision detection of object distance and position. The control module 4 may also include a circuit board and an FPC for electrical connection to the electromagnet assembly.

[0061] Optionally, such as Figures 1 to 2 As shown, the lens assembly 2 is provided with two sets, and the two sets of lens assemblies 2 are respectively assembled on the lens body 1 through the fixed bracket 21. The adjustment component 3 can adjust the focal length of the two sets of lens modules 22 respectively.

[0062] Specifically, in this embodiment, the lens assembly 2 is configured as two sets, respectively mounted on corresponding positions on the left and right sides of the lens body 1 via fixing brackets 21. This allows for independent adjustment of the focal length of each eye, significantly improving the adaptability and wearing comfort of the smart glasses. The two lens modules 22 can be controlled separately by the adjustment component 3, enabling individual adjustment of their focal lengths according to the different refractive states, myopia, or presbyopia of the user's left and right eyes. This ensures that both eyes achieve clear and balanced imaging, avoiding dizziness, double vision, and visual fatigue caused by inconsistent accommodation in one eye. Independent focal length adjustment for both eyes also accommodates individuals with anisometropia, meeting the needs of a wider range of visual conditions.

[0063] The symmetrical and flexible structure ensures that the appearance is similar to ordinary glasses while greatly improving the personalized adaptability and optical user experience of smart glasses.

[0064] Optionally, such as Figures 1 to 2 As shown, the mirror body 1 includes a front shell 11 and a rear shell 12, and a receiving cavity 13 is formed between the front shell 11 and the rear shell 12. The control module 4 is assembled in the receiving cavity 13.

[0065] Specifically, in this embodiment, the lens body 1 is designed with a front shell 11 and a rear shell 12 that fit together, forming a receiving cavity 13 between them. The control module 4 can be stably assembled in the internal receiving cavity 13. This structure provides good protection, dustproofing, and waterproofing for the control module 4, avoiding external collisions and environmental interference. At the same time, it makes the lens body 1 simple and beautiful in appearance, with a compact and regular overall structure, which is conducive to improving the reliability and service life of the smart glasses.
