Description

Technical Field

[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.

[0024] The following is combined with Figures 1-30 This application describes smart glasses according to embodiments thereof.

[0025] 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, an adjustment mechanism 3, and a control module 4; the lens module 2 includes a fixed bracket 21, a transparent elastic sheet 22, and at least one lens, the periphery of the at least one lens being sequentially mounted on the fixed bracket 21 along the thickness direction of the lens module 2 (refer to the X direction in the figure), and the elastic sheet 22 being spaced apart along the thickness direction on one side of one of the lenses; the adjustment mechanism 3 is movably mounted on the fixed bracket 21 and cooperates with the periphery of the elastic sheet 22; the control module 4 can drive the elastic sheet 22 to deform through the adjustment mechanism 3 to adjust the focal length of the lens module 2.

[0026] Specifically, in this embodiment, the lens module 2 consists of a fixed bracket 21, a transparent elastic sheet 22, and at least one lens. At least one lens is sequentially mounted on the fixed bracket 21 along the thickness direction of the lens module 2. Similarly, the transparent elastic sheets 22 are spaced apart along the thickness direction on one side of one of the lenses, forming a stacked lens assembly structure. The adjustment mechanism 3 is movably connected to the fixed bracket 21 and simultaneously engages with the periphery of the elastic sheet 22, forming an adjustable structure capable of driving deformation. The transparent elastic sheet 22 can be made of materials such as TPU, TPE, TPR, silicone, or POE. The at least one lens can be a convex lens, a concave lens, or a combination of both, designed according to actual needs. The shape of the elastic sheet 22 is the same as the shape of the lens, facilitating the formation of the lens module 2 together with the lenses.

[0027] The fixed bracket 21 provides a stable mounting base for the lens, elastic sheet 22 and adjustment mechanism 3, so that the components are arranged in an orderly manner and reliably positioned in the thickness direction. This ensures the compactness and stability of the overall structure of the lens module 2, and also reserves reasonable space for the controllable deformation of the elastic sheet 22, so as to achieve stable and precise structural cooperation between the components and provide reliable structural support for the subsequent focus adjustment function.

[0028] Furthermore, the control module 4 drives the adjustment mechanism 3, which is movably mounted on the fixed bracket 21, to apply a controllable force to the periphery of the elastic sheet 22, thereby causing the transparent elastic sheet 22 to undergo a preset deformation, allowing the elastic sheet 22 to expand or retract in the thickness direction of the lens module 2. Since the elastic sheets 22 are spaced apart on one side of the lens, their deformation (expansion or retraction, see reference)... Figure 27 and Figure 28 This directly alters the overall optical surface shape and light refraction path of lens module 2, thereby changing its refractive index and equivalent focal length. This process does not require lens replacement or manual eyeglass changing; instead, the control module 4 outputs a control signal, which is then converted into mechanical displacement and deformation by the adjustment mechanism 3. This achieves continuous and dynamic adjustment of the focal length of lens module 2, allowing the eyeglasses to adaptively adjust the imaging focal length according to the actual viewing distance, completing the process of clear imaging of objects at different distances from far to near. (Reference) Figure 30 After the refraction angle P changes, the lens module can focus the light from external objects onto the retina of the human eye 6, with an intraocular focal length of Y.

[0029] The adjustment mechanism 3 can be a circumferential multi-point pushing adjustment mechanism 3, including multiple driving push rods evenly arranged on the fixed bracket 21 along the circumference of the elastic sheet 22. Each push rod is electrically connected or mechanically linked to the control module 4. The control module 4 drives the push rods to extend and retract along the thickness direction of the lens module 2, applying multi-point synchronous pushing or pulling to the periphery of the elastic sheet 22, causing the elastic sheet 22 to produce uniform curved surface deformation, thereby continuously changing the curvature and focal length of the lens module 2. The adjustment mechanism 3 can also be a piezoelectric ceramic driven adjustment mechanism 3, with piezoelectric ceramic sheets / piezoelectric stacks arranged between the periphery of the elastic sheet 22 and the fixed bracket 21. The control module 4 applies a voltage signal to the piezoelectric ceramic, and the piezoelectric ceramic produces micro-displacement elongation or contraction under the action of the electric field, directly driving the deformation of the elastic sheet 22. The adjustment mechanism 3 can also be an electromagnetically driven adjustment mechanism 3. The adjustment mechanism 3 includes a coil, a permanent magnet and an elastic reset component. The coil is fixed on the fixed bracket 21, and the permanent magnet is located around the elastic sheet 22. The control module 4 supplies a variable current to the coil, which generates a magnetic field that interacts with the permanent magnet to form an attractive or repulsive force, causing the elastic sheet 22 to deform. After the power is cut off, the reset component restores the original state.

[0030] By employing a structural design that adjusts the focal length of the lens module 2 through the deformation of the elastic sheet 22, the limitations of traditional nearsighted and presbyopic glasses—fixed focal length and limited applicability—are effectively overcome, significantly enhancing the glasses' adaptive adjustment capabilities. When observing objects at different distances, users no longer need to change multiple pairs of glasses or periodically replace lenses based on prescription changes. The control module 4 automatically or manually adjusts the focal length, ensuring the image focuses precisely on the retina, achieving continuous clear imaging of objects at both near and far distances. Simultaneously, the structure, combining a fixed bracket 21 with a movable adjustment mechanism 3 and the elastic sheet 22, is compact and reliable, facilitating integration into the smart glasses body 1. This ensures optical adjustment accuracy while improving ease of use and comfort. This technical solution enables intelligent and dynamic adjustment of the glasses' focal length, broadening the range of clear visual distances, reducing the inconvenience of frequent glasses changes, and better meeting users' visual needs in different scenarios.

[0031] Optionally, such as Figures 4 to 13 As shown, the adjustment mechanism 3 includes a tension / compression assembly, a magnetic assembly, and a spring assembly. The tension / compression assembly has an initial state and a stretched state. The tension / compression assembly is movably mounted on the fixed bracket 21. The periphery of the elastic sheet 22 is fitted with the tension / compression assembly. The magnetic assembly and the spring assembly are respectively mounted on the tension / compression assembly. The control module 4 can control the magnetic assembly to change the tension / compression assembly from the initial state to the stretched state, so as to drive the elastic sheet 22 to deform. The spring assembly can restore the tension / compression assembly from the stretched state to the initial state.

[0032] Specifically, in this embodiment, an adjustment mechanism 3 employing a combination of a tension / compression component, a magnetic component, and a spring component enables stable driving and reliable reset of the elastic sheet 22's deformation, thereby precisely adjusting the focal length of the lens module 2. The tension / compression component is movably mounted on the fixed bracket 21, with the elastic sheet 22's periphery interlocking with it. This tight fit and direct transmission ensure uniform transmission of the deformation force, improving focusing accuracy and stability. The control module 4 controls the magnetic component to drive the tension / compression component from its initial state to a stretched state, thereby causing controllable deformation of the elastic sheet 22 and actively adjusting the focal length of the lens module 2 to meet the user's need for clear imaging of objects at different distances. Simultaneously, the spring component provides a reset driving force for the tension / compression component, smoothly restoring it from the stretched state to its initial state when the magnetic component stops working, allowing the elastic sheet 22 to return to its original shape and achieving reversible focal length adjustment.

[0033] The adjustment mechanism 3 provided in this application has a compact structure, rapid action response, and reliable operation. It not only realizes the electronic control adjustment of the focal length but also has an automatic reset function, which can restore the initial state without additional drive. It effectively simplifies the structure, reduces power consumption, improves the stability and convenience of using smart glasses, can adapt to the continuous focusing needs in different scenarios, extends the service life of the device, and optimizes the user's wearing experience.

[0034] Optionally, such as Figures 4 to 13 As shown, the fixed bracket 21 is configured as a ring structure; the tension and compression assembly includes a first tension and compression strip 31 and a second tension and compression strip 32, which are arranged opposite to each other and movably pass through the ring wall of the fixed bracket 21, with both ends extending out of the fixed bracket 21; the elastic sheet 22 is located between the first tension and compression strip 31 and the second tension and compression strip 32, and the periphery of the elastic sheet 22 is respectively fitted and assembled with the first tension and compression strip 31 and the second tension and compression strip 32; the magnetic assembly and the spring assembly are both assembled at the ends of the first tension and compression strip 31 and the second tension and compression strip 32.

[0035] Specifically, in this embodiment, the fixed bracket 21 is designed as a ring structure, which provides a stable and symmetrical mounting base for the lens, elastic sheet 22, and adjustment mechanism 3, ensuring that the overall structure of the lens module 2 is regular and the force is uniform. The tension-compression assembly uses a first tension strip 31 and a second tension strip 32 arranged opposite to each other. Both are movably inserted through two mounting holes 211 on the ring wall of the ring fixed bracket 21, and both ends extend out of the fixed bracket 21 from the two mounting holes 211. This facilitates the arrangement of the magnetic component and the spring component, and also enables stable guiding movement, avoiding skewing or jamming during movement. The first tension strip 31 and the second tension strip 32 can be made of materials such as polycarbonate, polyoxymethylene, glass fiber reinforced nylon, aluminum alloy, and stainless steel. In addition, the gap between the elastic sheet 22 and the lens is achieved by clamping a sealing ring 25, or the size of the elastic sheet 22 can be smaller than the width of the first tension strip 31 and the second tension strip 32 in the width direction of the lens module 2, such as... Figure 11 , Figure 22 and Figure 23 As shown, the specific design should be based on actual needs.

[0036] In this embodiment, the elastic sheet 22 is confined between the first tension strip 31 and the second tension strip 32, and its periphery is respectively fitted and assembled with the two tension strips. This allows the movement of the tension strips to be smoothly and synchronously transmitted to the elastic sheet 22, achieving symmetrical and uniform deformation of the elastic sheet 22. This effectively ensures the consistency of the optical surface change of the lens module 2, improving focusing accuracy and image quality. The magnetic component and spring component are assembled at the end of the tension strip, making full use of the end space and making the overall structure more compact, which is beneficial to the lightweight design of smart glasses. This structure, through the symmetrical double tension strips and the ring bracket, achieves reliable, stable, and symmetrical driving and resetting of the elastic sheet 22. It has the advantages of simple structure, smooth movement, and precise focusing, which can significantly improve the reliability of focus adjustment and user experience of smart glasses.

[0037] Optionally, such as Figures 12 to 13 As shown, the first end of the first tension strip 31 is opposite to the first end of the second tension strip 32, and the second end of the first tension strip 31 is opposite to the second end of the second tension strip 32; the magnetic assembly includes at least two pairs of magnets, each pair of magnets being respectively assembled at the first end of the first tension strip 31 and the first end of the second tension strip 32, or respectively assembled at the second end of the first tension strip 31 and the second end of the second tension strip 32, each pair of magnets including at least one electromagnet 34, at least one electromagnet 34 being electrically connected to the control module 4; and / or, the spring assembly includes at least two spring members, the two ends of each spring member being respectively connected to the ends of the first tension strip 31 and the second tension strip 32, so that the first tension strip 31 and the second tension strip 32 are connected in a ring shape.

[0038] Specifically, in this embodiment, by arranging the first tension bar 31 and the second tension bar 32 opposite to each other at both ends, and cooperating with at least two pairs of magnets and at least two spring components, a symmetrical and stable closed-loop driving and reset structure is formed. The magnetic component uses multiple pairs of magnets arranged at both ends of the tension bar, with at least one electromagnet 34 electrically connected to the control module 4. The magnetic field strength can be precisely controlled electronically to stably drive the tension bars to produce different degrees of opposite movement, or to restore the opposite movement to its initial state by removing power, thus achieving precise control of the deformation of the elastic sheet 22 and ensuring the response speed and adjustment accuracy of the lens module 2's focal length adjustment. The control module 4 may include a circuit board 41 and electrical connectors 42. Each electromagnet 34 can be electrically connected to the circuit board 41 through its respective electrical connector 42. Figure 15 , Figures 17 to 19 .

[0039] The spring component is connected to the ends of two tension bars at each end, forming a ring-shaped integral structure. (Refer to...) Figure 12 and Figure 13 This design provides a uniform and reliable reset force for the tension bar when the electromagnet 34 is de-energized, while also enhancing the overall structural rigidity and stability, preventing swaying or displacement during operation. The symmetrical end-drive and reset layout ensures balanced force distribution and direct transmission, effectively guaranteeing uniform deformation of the elastic sheet 22 and improving image quality. Furthermore, its compact structure and easy assembly facilitate miniaturization and lightweight design of smart glasses. It also boasts advantages such as reliable adjustment, stable reset, and long service life, significantly improving the practicality and user experience of smart glasses' focus adjustment.

[0040] Optionally, such as Figure 5 As shown, the two ends of the first tension strip 31 and the two ends of the second tension strip 32 are respectively connected to the assembly plates; each magnet is embedded in the corresponding assembly plate, and the two ends of each spring are respectively connected to the two corresponding assembly plates.

[0041] Specifically, in this embodiment, by providing mounting plates at both ends of the first tension strip 31 and the second tension strip 32, magnets are embedded in the corresponding mounting plates, and the two ends of the spring are connected to the opposite mounting plates, providing a stable and orderly mounting carrier for the magnetic assembly and the spring assembly. The mounting plates increase the assembly area of ​​the magnet and the spring, improving the installation firmness and positioning accuracy, preventing loosening or displacement of the magnet and the spring during frequent reciprocating motion, and ensuring stable and reliable driving and resetting actions. Figure 4 and Figure 5As shown, the upper end of the first tension strip 31 is equipped with a first mounting plate 311, and the upper end of the second tension strip 32 is equipped with a second mounting plate 321. The two mounting plates are arranged opposite to each other, so that after the electromagnet 34 and the permanent magnet 33 are respectively mounted on the first mounting plate 311 and the second mounting plate 321, the purpose of stretching the first tension strip 31 and the second tension strip 32 can be achieved by magnetic attraction.

[0042] The embedded and connected structure simplifies the overall assembly process, making it easier to process and assemble. It allows the tension strip, magnet, and spring to form an integrated ring-shaped drive structure, resulting in more uniform force distribution and smoother movement. This effectively improves the stability and consistency of the focal length adjustment of the lens module 2, extends its service life, and further optimizes the structural reliability and user experience of the smart glasses.

[0043] Optionally, such as Figures 16 to 19 As shown, the smart glasses also include a positioning component, which is disposed on the lens body 1 and is used to limit the position of the first tension strip 31 and the second tension strip 32.

[0044] Specifically, in this embodiment, the positioning component is used to limit the position of the first tension strip 31 and the second tension strip 32, which can effectively prevent problems such as shaking, offset, or misalignment of the tension strips during reciprocating motion, ensuring that they always move stably along the preset direction. The positioning component can provide reliable guidance and constraint for the tension strips, making the elastic sheet 22 more uniformly stressed and its deformation more controllable, thereby improving the accuracy and stability of the focal length adjustment of the lens module 2. At the same time, reasonable position restriction can reduce frictional loss between the tension strips and other components, reduce the risk of motion jamming, and improve the reliability and service life of the overall structure. This setting is simple in structure and easy to implement. Without significantly increasing the volume and weight of the glasses 1, it greatly improves the operational stability of the focusing mechanism, ensuring that the smart glasses can work stably in different usage scenarios and optimizing the user experience.

[0045] Optionally, such as Figures 16 to 19 As shown, the positioning component includes a first positioning groove 37 and a second positioning groove; the first end of the first tension strip 31 and the first end of the second tension strip 32 are respectively positioned opposite each other and confined within the first positioning groove 37, and the second end of the first tension strip 31 and the second end of the second tension strip 32 are respectively positioned opposite each other and confined within the second positioning groove; the first positioning groove 37 and the second positioning groove are used to restrict the degree of freedom of the first tension strip 31 and the second tension strip 32 along their stretching direction.

[0046] Specifically, in this embodiment, a positioning assembly consisting of a first positioning groove 37 and a second positioning groove is used to precisely constrain the movement trajectories of the first tension bar 31 and the second tension bar 32, thereby achieving stable and reliable linear movement of the adjustment mechanism 3. The two ends of the first tension bar 31 and the second tension bar 32 are respectively confined within the two positioning grooves, retaining only the degree of freedom of movement along the stretching direction. This effectively prevents radial swaying, lateral offset, or torsional misalignment of the tension bars during reciprocating motion, ensuring that the tension bars always move smoothly along the preset direction.

[0047] This positioning groove structure ensures that the elastic sheet 22 is subjected to uniform force and symmetrical deformation under the drive of the tension strip, significantly improving the accuracy and optical stability of the lens module 2's focal length adjustment and guaranteeing clear and reliable imaging. At the same time, the groove limiting structure is simple and compact, facilitating assembly without increasing the overall size and weight of the smart glasses, thus contributing to a thinner and lighter product design.

[0048] This embodiment reduces friction and wear between components by reasonably restricting the degrees of freedom of movement, reduces the risk of jamming, and improves the service life and operational stability of the focusing mechanism. It provides structural protection for smart glasses to achieve continuous, accurate, and reliable focus adjustment, and enhances the stability and comfort of users during use.

[0049] Optionally, such as Figures 16 to 19 As shown, the positioning assembly also includes multiple flat-head positioning posts 38, with the two ends of the first tension strip 31 and the two ends of the second tension strip 32 respectively bypassing one of the flat-head positioning posts 38 and being confined within the first positioning groove 37 or the second positioning groove.

[0050] Specifically, in this embodiment, the two ends of the first and second tension bars 31 and 32 are respectively bypassed by the corresponding flat-head positioning posts 38 and then confined within the first or second positioning groove. Through the dual cooperation of the flat-head positioning posts 38 and the positioning grooves, the guiding accuracy and stability of the tension bar movement are further improved. The flat-head positioning posts 38 have smooth surfaces, which can guide and transition during the reciprocating motion of the tension bars, reducing friction and jamming risks between the bars and components, and avoiding damage caused by edge stress concentration. Simultaneously, the positioning posts can pre-position and limit the tension bars, preventing them from swaying, shifting, or tangling during stretching and resetting, ensuring consistent movement direction.

[0051] The structure provided in this embodiment is simple and reliable, easy to assemble, effectively improves the operational stability and service life of the focusing mechanism, ensures accurate and smooth focal length adjustment of the lens module 2, and enhances the overall structural stability and reliability of the smart glasses.

[0052] Optionally, such as Figure 6 , Figure 7 , Figure 22 and Figure 23 As shown, the first tension strip 31 and the second tension strip 32 are respectively provided with one of the protrusions 312 and the groove 221 on the side facing the elastic sheet 22, and the other of the protrusions 312 and the groove 221 is provided on the periphery of the elastic sheet 22; the elastic sheet 22 is located between the first tension strip 31 and the second tension strip 32 through the fitting of the protrusions 312 and the groove 221.

[0053] Specifically, in this embodiment, an assembly structure in which a protrusion 312 and a groove 221 engage at the mating points of the first tension strip 31, the second tension strip 32, and the elastic sheet 22 ensures that the elastic sheet 22 is stably confined between the two tension strips. The interlocking of the protrusion 312 and the groove 221 significantly improves the connection strength and positioning accuracy between the tension strip and the elastic sheet 22, preventing relative sliding, misalignment, or loosening during stretching and resetting. This ensures that the driving force is efficiently and stably transmitted to the elastic sheet 22, guaranteeing the accuracy and consistency of deformation adjustment.

[0054] The fitting method provided in this embodiment is simple to assemble and reliable, achieving a reliable connection without the need for additional fasteners. This simplifies the structure, improves assembly efficiency, and ensures uniform stress distribution on the elastic sheet 22, avoiding localized stress concentration and extending the component's lifespan. The overall structure guarantees precise and smooth focusing action while enhancing the structural stability of the lens module 2, providing strong support for reliable and continuous focus adjustment in smart glasses.

[0055] In one embodiment, the lens module 2 includes an annular fixing bracket 21, an inner lens 23, a spring, an outer lens 24, and two sealing rings 25. The inner ring of the fixing bracket 21 is provided with an assembly groove. The inner lens 23, the spring, and the outer lens 24 are sequentially and spaced apart in the assembly groove of the fixing bracket 21. The two sealing rings 25 are respectively sandwiched between the inner lens 23 and the side wall of the assembly groove, and between the outer lens 24 and the other side wall of the assembly groove, to achieve sealed assembly of the lens module 2. The adjustment mechanism 3 includes a first tension bar 31 and a second tension bar 32 movably mounted on the annular bracket. The two ends of the first tension bar 31 and the second tension bar 32 are respectively connected to assembly plates. A permanent magnet 33 and an electromagnet 34 are respectively mounted on the two opposite assembly plates. The electromagnet 34 is connected to the control module 4. A first spring 35 and a second spring 36 are connected between the two opposite assembly plates.

[0056] In practical applications, when the adjusting mechanism 3 is in its initial state, the reference is... Figure 22 , Figure 24 , Figure 26 and Figure 27When the control module 4 controls the adjustment mechanism 3 to be in a stretched state, the control module 4 energizes the electromagnet, causing the two opposing assembly plates to attract each other under magnetic force, thereby tightening the first tension strip 31 and the second tension strip 32. This compresses the elastic sheet 22, causing it to deform in the thickness direction, i.e., expand and bulge, thus adjusting the focal length of the lens module 2. (Refer to...) Figure 21 , Figure 23 , Figure 25 , Figure 28 and Figure 29 The deformation of the elastic element can be controlled by controlling the magnitude of the electromagnetic force of the permanent magnet 33. When it is necessary to adjust the mechanism 3 back to the initial state, the electromagnet 34 can be de-energized. The whole control process is simple and controllable.

[0057] Optionally, such as Figures 2 to 3 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 working state of the adjustment mechanism 3 according to the position parameters.

[0058] Specifically, in this embodiment, by adding a detection module 5 electrically connected to the control module 4, the position parameters of external objects can be acquired in real time. This allows the control module 4 to precisely control the working state of the adjustment mechanism 3 according to the actual distance to the object, thereby achieving adaptive adjustment of the smart glasses' focal length. The detection module 5 can be a distance sensor, an infrared sensor, a visual camera, a laser ranging module, or an ultrasonic sensor.

[0059] The detection module 5 converts external environmental information into electrical signals and feeds them back to the control module 4. The system can quickly determine the viewing distance and drive the elastic sheet 22 to deform, so that the imaging focus automatically falls on the retina. The switching between near and far scenes can be completed without manual operation by the user, which improves the intelligence and real-time adjustment of the glasses, expands the range of clear vision, and solves the problems of traditional glasses that need to be manually replaced and have limited adaptability. It is more convenient to use, responds more quickly, and greatly improves the user's wearing experience.

[0060] Optionally, such as Figure 1 , Figure 2 , Figure 14 , Figure 16 and Figure 20 As shown, there are two sets of lens modules 2 and adjustment mechanisms 3 respectively; the two sets of lens modules 2 are respectively mounted on the lens body 1 through the fixed bracket 21, and the control module 4 can adjust the focal length of the two sets of lens modules 2 one by one through the two sets of adjustment mechanisms 3.

[0061] Specifically, in this embodiment, the lens module 2 and the adjustment mechanism 3 are configured as two sets, each independently mounted on the lens body 1 via a fixing bracket 21, allowing for focal length adjustment for each of the user's eyes. The control module 4 can independently control the corresponding lens module 2 through the two sets of adjustment mechanisms 3, achieving individual and precise adjustment of the focal length for the left and right eyes. This meets the personalized needs of different users with varying refractive states in both eyes, effectively improving image clarity and wearing comfort. The two sets of adjustment mechanisms 3 are independent and do not interfere with each other. They can adjust the focal length synchronously or separately based on the viewing distance obtained by the detection module 5, ensuring consistent visual effects for both eyes and avoiding visual fatigue caused by asynchronous adjustment.

[0062] The structure provided in this embodiment is flexible and highly adaptable, covering various vision conditions such as myopia and presbyopia, improving the versatility and practicality of smart glasses, and providing users with a more stable, comfortable, and intelligent visual experience.

[0063] Optionally, such as Figure 2 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 4 and part of the adjustment mechanism 3 are both assembled in the receiving cavity.

[0064] Specifically, in this embodiment, the mirror body 1 is configured with a front shell 11 and a rear shell 12 that fit together, forming a cavity between them. This provides a closed and stable installation space for the control module 4 and some adjustment mechanisms 3, enabling the integrated arrangement of internal components.

[0065] The control module 4 and part of the adjustment mechanism 3 are assembled inside the housing cavity, which can effectively prevent damage to electronic and moving parts caused by external dust, moisture, collisions, etc., and improve the overall reliability and service life of the smart glasses. At the same time, the built-in installation structure helps to optimize the shape of the lens body 1, making the appearance more concise and beautiful, realizing the product's thinner and smaller design, and improving wearing comfort and aesthetics.

[0066] The structure is easy to assemble and has a compact layout. The wiring and transmission connections between the components are shorter and more stable, reducing the probability of interference and failure, and providing reliable structural protection and spatial support for the intelligent focusing function of smart glasses.
