Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and more particularly to a smart glasses and a smart glasses component. Background Technology

[0002] Due to the requirements of lightweight, miniaturization, and wearing comfort, smart glasses have limited internal battery capacity, resulting in short battery life. Among various charging technologies, wireless charging has become the standard charging method for smart glasses due to its advantages such as no need for plugging and unplugging, improved waterproof and dustproof performance, and reduced interface wear. Compared to contact charging methods such as Type-C and Pogo Pin, wireless charging reduces oxidation, corrosion, and poor contact problems caused by user sweat in high-temperature and high-humidity environments like summer. To improve wireless charging performance, receiving coils are often placed on both the left and right frames of the glasses to expand the overall sensing area and enhance magnetic flux capture capabilities. Compared to structures with receiving coils on only one side (left or right), the dual-sided distribution design significantly improves the magnetic field coupling efficiency with external transmitting devices, especially when the user's wearing posture changes or the charging position shifts, maintaining a relatively stable energy reception capability and thus improving charging efficiency. However, this method requires two sets of rectification, matching, or switching circuits, occupying circuit board space and hindering miniaturization. In addition, the wiring and integration of the coils require high-precision manufacturing processes, resulting in low production efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide smart glasses and smart glasses components, which aim to improve charging efficiency, simplify circuit design, and increase the integration of smart glasses.

[0004] To achieve the above objectives, the present invention proposes a smart glasses, the smart glasses comprising:

[0005] Left half-frame component and right half-frame component;

[0006] An intermediate connection structure is provided, through which the left half-frame component and the right half-frame component are connected;

[0007] A receiving coil, consisting of a metal conductor, is located in the left half-frame assembly, and another part of the receiving coil is located in the right half-frame assembly;

[0008] The receiving coil is used to receive electrical energy wirelessly.

[0009] In one embodiment, the receiving coil includes a DD coil, comprising a first D-shaped region and a second D-shaped region, wherein the first D-shaped region and the second D-shaped region are connected via an intermediate connecting structure;

[0010] The winding direction of the metal conductor corresponding to the first D-shaped region is opposite to that of the metal conductor corresponding to the second D-shaped region.

[0011] In one embodiment, the metal conductor is led out from its starting end, wound around the periphery of the left half-frame assembly, and extended to the right half-frame assembly through the intermediate connecting structure, and then wound around the periphery of the right half-frame assembly and returned to the starting end through the intermediate connecting structure to form a closed coil.

[0012] In one embodiment, the left half-frame assembly includes a first lens and a left frame, the left frame being disposed around the first lens;

[0013] The right half-frame assembly includes a second lens and a right side frame, the right side frame being disposed around the second lens, and the left side frame and the right side frame being connected by the intermediate connecting structure;

[0014] The receiving coil is located within the left frame and the right frame.

[0015] In one embodiment, the left half-frame assembly includes a first lens, a left frame, and a left temple, the left frame being disposed around the first lens and connected to the left temple;

[0016] The right half-frame assembly includes a second lens, a right side frame, and a right temple. The right side frame is arranged around the second lens and connected to the right temple. The left side frame and the right side frame are connected by the intermediate connecting structure.

[0017] The receiving coil is located inside the left temple and the right temple.

[0018] The present invention also proposes a smart glasses assembly, including the smart glasses described in any one of the above claims, and a charging case, the charging case having a receiving cavity for accommodating the smart glasses, the charging case including a transmitting coil disposed within the receiving cavity;

[0019] The charging box outputs electrical energy through the transmitting coil to charge the smart glasses.

[0020] In one embodiment, when the smart glasses are placed in the accommodating cavity, the transmitting coil and the receiving coil of the smart glasses are in a magnetically resonant coupled state, so that the charging case can charge the smart glasses.

[0021] In one embodiment, the area of ​​the transmitting coil is greater than or equal to the area of ​​the receiving coil.

[0022] In one embodiment, the charging case includes a cover and a cavity, the cover covering the cavity to form the receiving cavity;

[0023] When the receiving coil is located within the left side frame of the left half-frame assembly and the right side frame of the right half-frame assembly, the transmitting coil is located within the cover body.

[0024] When the receiving coil is located inside the left temple of the left half-frame assembly and the right temple of the right half-frame assembly, the transmitting coil is located inside the cavity.

[0025] In one embodiment, when the smart glasses are placed in the accommodating cavity, the receiving coil and the transmitting coil are located on the same horizontal plane.

[0026] In practical applications, when a user places the smart glasses on the accompanying wireless charging stand or charging case, the transmitting coil on the stand or case outputs electrical energy to charge the glasses. Compared to solutions that place the receiving coil only on one side of the left or right half of the frame, the single-coil structure distributed on both sides effectively increases the coupling area and maintains a relatively stable energy reception capability even when the charging position shifts, thereby improving charging efficiency. Furthermore, since only a single coil is used, there is no need for multiple coil matching circuits or switching switches, simplifying circuit design, increasing the integration of the smart glasses, and reducing the risk of electromagnetic interference between multiple coils.

[0038] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the present invention and are not intended to limit the present invention.

[0040] To better understand the technical solution of the present invention, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0041] Due to the requirements of lightweight, miniaturized, and comfortable wearing, smart glasses products, such as AI (Artificial Intelligence Glasses) / AR (Augmented Reality Glasses), have limited internal battery capacity, typically only around 200mAh, resulting in short battery life. Among various charging technologies, wireless charging has become the standard charging method for smart glasses due to its advantages such as no need for plugging and unplugging, improved waterproof and dustproof performance, and reduced interface wear. Compared to contact charging methods such as Type-C and Pogo Pin, wireless charging reduces the oxidation, corrosion, and poor contact problems caused by user sweat in high-temperature and high-humidity environments like summer. To improve wireless charging performance, receiving coils are often placed on both the left and right frames of the glasses to expand the overall sensing area and enhance magnetic flux capture capabilities. Compared to structures with receiving coils on only one side (left or right), the dual-sided distribution design significantly improves the magnetic field coupling efficiency with external transmitters, especially when the user's wearing posture changes or the charging position shifts, maintaining a relatively stable energy reception capability, thereby improving charging efficiency. However, this method of independently setting two receiving coils on the left and right sides requires two sets of rectification, matching, or switching circuits, which takes up board space, hinders miniaturization, and may also lead to energy loss due to electromagnetic interference or phase mismatch between the two coils. In addition, the wiring and integration of the coils have high requirements for manufacturing processes and low production efficiency.

[0042] Furthermore, if only a single receiving coil is placed on the left or right side of the smart glasses, although the structure is simple, the effective receiving area is limited, making it difficult to meet the charging needs of high-power devices such as AR glasses. At the same time, magnetic field coupling has strong directionality and position dependence, and even a slight positional deviation may lead to charging failure. In addition, to compensate for efficiency loss, it is often necessary to increase the driving power or extend the charging time, which affects user experience and charging safety.

[0043] Therefore, refer to Figure 1 The present invention proposes a smart glasses 100, the smart glasses 100 comprising:

[0044] Left half-frame component 10 and right half-frame component 20;

[0045] The left half-frame component 10 and the right half-frame component 20 are connected by the intermediate connection structure 30.

[0046] The receiving coil 40 is composed of a metal conductor. A portion of the receiving coil 40 is located in the left half-frame assembly 10, and the other portion of the receiving coil 40 is located in the right half-frame assembly 20.

[0047] The receiving coil 40 is used to receive electrical energy wirelessly.

[0048] In this embodiment, the smart glasses 100 include, but are not limited to, AR glasses, AI glasses, etc.

[0049] In this embodiment, the left half-frame assembly 10 can be the left frame and left temple 13, and the right half-frame assembly 20 can be the right frame and right temple 23. The intermediate connecting structure 30 is a flexible or hinged nose bridge that connects the left half-frame assembly 10 and the right half-frame assembly 20, allowing for a certain angle adjustment to fit different user facial contours. The receiving coil 40 is used to wirelessly receive electrical energy from the external transmitting coil 01 to achieve wireless charging.

[0050] In this embodiment, the receiving coil 40 can be a magnetic induction receiving coil, and correspondingly, the external transmitting coil 01 is a magnetic induction transmitting coil. When alternating current passes through the transmitting coil 01, an alternating magnetic field is generated. This magnetic field passes through the adjacent receiving coil 40, inducing an electromotive force in the receiving coil 40, thereby realizing energy transfer. Optionally, the receiving coil 40 can also be a magnetic resonance receiving coil, and correspondingly, the external transmitting coil 01 is a magnetic resonance transmitting coil. The LC circuits of the transmitting and receiving ends are tuned to the same resonant frequency, achieving efficient energy transfer through the transmitting coil 01 and the receiving coil 40 in a resonant state. It is understood that... NFC and Qi standard wireless charging methods require coil designs that strictly adhere to international standards and rely on high alignment and strong magnetic coupling between the transmitting and receiving coils 40. When applying traditional Qi or NFC architectures to smart glasses 100, the narrow and curved frame makes it difficult to arrange the receiving coil 40 into a regular plane, leading to alignment difficulties with the transmitting coil 01. Consequently, the mutual inductance and coupling coefficient (k) between the transmitting coil 01 and the receiving coil 40 are much lower than those in planar devices such as mobile phones, resulting in low charging efficiency. Using magnetic induction and magnetic resonance wireless charging methods can achieve higher magnetic flux capture capabilities, improve mutual inductance and overall system efficiency, and significantly enhance charging efficiency at the same input power.

[0051] In this embodiment, the metal conductor can be made of copper, copper alloy, aluminum, silver, etc. In this embodiment, a portion of the metal conductor is wound with N1 turns along the inner edge or internal channel of the left half-frame assembly 10 to form the left sensing area; the metal conductor extends to the right side via a wire channel passing through the interior of the intermediate connecting structure 30; and N2 turns are wound at the corresponding position on the right half-frame assembly 20 to form the right sensing area. N1 and N2 are equal and are set by the researchers.

[0052] It should be noted that the smart glasses 100 also includes a circuit board, which contains a rectifier circuit, a voltage regulator circuit (such as a DC-DC converter), and a charging management chip (such as a charger IC). The entire receiving coil 40 forms a single-turn circuit, with its two ends connected to the rectifier circuit. This rectifier circuit converts the AC power received by the receiving coil 40 into DC power, which is then output to the voltage regulator circuit (such as a DC-DC converter) to stabilize the voltage to a suitable charging level. Finally, a stable DC power is output to the charger IC. In this way, the charger IC can control the charging current and charging voltage, and provide overvoltage, overcurrent, and overheat protection to ensure the safety of charging the smart glasses 100.

[0053] In this embodiment, the left half-frame assembly 10 and the right half-frame assembly 20 can be made of non-metallic materials to reduce the shielding effect on the magnetic field. The surface of the receiving coil 40 can also be coated with a waterproof and sweat-proof resin layer to improve corrosion resistance and reliability in high temperature, high humidity, and sweating environments.

[0054] In practical applications, when a user places the smart glasses 100 on the matching wireless charging stand or inside the charging case 200, the transmitting coil 01 of the wireless charging stand or charging case 200 outputs electrical energy to charge the smart glasses 100. Compared to a solution that only sets the receiving coil 40 on one side of the left half-frame assembly 10 or the right half-frame assembly 20, the single-coil structure distributed on both sides can effectively increase the coupling area and maintain a relatively stable energy receiving capability even when the charging position is offset, thereby improving the charging success rate and average power. In addition, since only a single coil is used, there is no need to configure multiple sets of coil matching circuits or switching switches, which simplifies the circuit design, improves the integration of the smart glasses 100, and reduces the risk of electromagnetic interference between multiple coils.

[0055] Optionally, in one embodiment, the receiving coil 40 includes a DD coil, including a first D-shaped region and a second D-shaped region, wherein the first D-shaped region and the second D-shaped region are connected via an intermediate connection structure 30;

[0056] The winding direction of the metal conductor corresponding to the first D-shaped region is opposite to that of the metal conductor corresponding to the second D-shaped region.

[0057] refer to Figure 2The first D-shaped region is located within the left half-frame assembly 10, and N1 turns can be wound along the arc-shaped edge of the left side of the frame. The second D-shaped region is located within the right half-frame assembly 20, and N2 turns can be wound along the arc-shaped edge of the right side of the frame. The first and second D-shaped regions are physically connected through a wire channel within the intermediate connecting structure 30, i.e., the metal conductor passes through the bridge portion of the nose to form a loop. The receiving coil 40 is a continuous DD-type single coil structure, forming a closed loop with a starting point and an ending point, conforming to the characteristics of a single coil. The metal conductor, starting from the first D-shaped region of the left half-frame assembly 10, passes through the intermediate connecting structure 30 of the bridge portion of the nose and extends to the second D-shaped region of the right half-frame assembly 20, ultimately forming a complete loop. The winding direction of the metal conductor corresponding to the first D-shaped region is opposite to the winding direction of the metal conductor corresponding to the second D-shaped region. For example, the first D-shaped region is wound in a clockwise direction, while the second D-shaped region is wound in a counterclockwise direction. In this way, the current flow directions of the two regions are spatially "differential," which causes the magnetic fields they generate to partially cancel each other out in the central intersection area. This provides directional selectivity to external alternating magnetic fields, effectively suppressing common-mode interference (such as environmental electromagnetic noise and geomineralization effects) and improving the signal-to-noise ratio. When aligned with the external transmitting coil 01, both D-shaped regions simultaneously capture magnetic field energy, enhancing mutual inductance. Even with slight misalignment, efficient coupling can still be maintained on at least one side.

[0058] In this embodiment, the overall effective area of ​​the DD-type coil is approximately twice that of a single D-shaped coil; the magnetic flux coverage is wider, and it can simultaneously couple with the magnetic fields on the left and right sides of the transmitting coil 01; therefore, compared with the single-sided single D-coil scheme, the DD coil has a higher coupling coefficient and significantly improved energy transmission efficiency.

[0059] This embodiment integrates a differentially wound DD-type coil into the frame of the smart glasses (around 100mm), achieving high-efficiency and strong anti-interference wireless charging, suitable for high-power, small-size wearable devices such as AI / AR glasses.

[0060] Optionally, in one embodiment, after the metal conductor is led out from its own starting end, it is wound along the periphery of the left half-frame assembly 10 and extended to the right half-frame assembly 20 through the intermediate connecting structure 30, and after being wound along the periphery of the right half-frame assembly 20, it returns to the starting end through the intermediate connecting structure 30 to form a closed coil.

[0061] refer to Figure 3The metal conductor spirally winds along the inner periphery of the left half-frame assembly 10 from its starting end, forming the left-side sensing area. Then, the metal conductor extends laterally to the right half-frame assembly 20 through a pre-set first wire channel inside the intermediate connecting structure 30; it continues winding along the corresponding periphery of the right half-frame assembly 20, forming the right-side sensing area. Finally, the metal conductor extends laterally back through the second wire channel of the intermediate connecting structure 30 and connects to the starting end, thus forming a complete closed loop. The first and second wire channels do not overlap.

[0062] By employing a single coil and distributing its winding across the left and right frames, the effective receiving area is nearly doubled compared to a single-sided coil, significantly enhancing the magnetic coupling coefficient with the external transmitting coil 01. Due to its strong magnetic flux capture capability, the overall energy conversion efficiency is higher than that of traditional single-sided small coil solutions, effectively reducing ineffective power consumption and temperature rise. Furthermore, compared to having a separate receiving coil 40 for each of the left half-frame assembly 10 and the right half-frame assembly 20, the matching circuit is reduced, thus decreasing the size and weight of the smart glasses 100.

[0063] In one embodiment, the left half-frame assembly 10 includes a first lens 11 and a left frame 12, the left frame 12 being disposed around the first lens 11;

[0064] The right half-frame assembly 20 includes a second lens 21 and a right side frame 22. The right side frame 22 is arranged around the second lens 21. The left side frame 12 and the right side frame 22 are connected by the intermediate connecting structure 30.

[0065] The receiving coil 40 is located within the left frame 12 and the right frame 22.

[0066] In this embodiment, the left frame 12 surrounds the outer periphery of the first lens 11, forming the overall structure of the left frame; the right frame 22 surrounds the outer periphery of the second lens 21, forming the structure of the right frame. The middle connecting structure 30 is the bridge of the nose, connecting the left frame 12 and the right frame 22.

[0067] In this embodiment, the left half-frame assembly 10 may further include a left temple 13, and the right half-frame assembly 20 may further include a right temple 23, for securing the wearer. In this embodiment, the receiving coil 40 is disposed within the left frame 12 and the right frame 22. The left frame 12 and the right frame 22 are typically wider and have a longer curvature than the temples, and have a large lateral span (close to the total width of the glasses), providing more wiring space for coil winding. Arranging the receiving coil 40 within the left and right frames 22 allows for a longer continuous winding path, significantly increasing the number of coil turns and the effective sensing area. A larger area means that more magnetic flux can be captured, resulting in higher mutual inductance and coupling coefficient (k) with the external transmitting coil 01, thereby improving wireless charging efficiency.

[0068] In this embodiment, the smart glasses 100 can also be a templeless structure, such as a headband structure, using a headband or Y-shaped headband fixation device that wraps around the head, resulting in a more even weight distribution and suitability for prolonged wear. Alternatively, it can adopt a clip-on design, not worn independently, but clipped onto the user's existing glasses. It can also be in the form of a full-coverage helmet or goggles. Thus, the receiving coil 40 is placed within the left frame 12 and the right frame 22, not limited by the specific structure of the smart glasses 100. Regardless of whether temples are provided, as long as there is a left and right frame structure, the coil can be deployed, ensuring high-performance wireless charging while improving flexibility and practicality.

[0069] It should be noted that the reference Figure 7 When the smart glasses 100 needs to be charged, it can be folded and placed in the corresponding charging dock or charging case 200. The charging dock or charging case 200 is equipped with a transmitting coil 01. When the smart glasses 100 is placed on the charging dock or in the charging case 200, the transmitting coil 01 should be as close as possible to the receiving coil 40. For example, if the frame of the smart glasses 100 is closer to the bottom of the charging dock or the bottom of the charging case 200 relative to the temples, the transmitting coil 01 can be placed at the bottom of the charging dock or the bottom of the charging case 200. If the transmitting coil 01 is placed at the bottom, the distance to the receiving coil 40 will be too far, and the coupling efficiency will decrease significantly. Therefore, the transmitting coil 01 can be placed at the top of the charging dock or the top of the charging case 200 to achieve the minimum distance and maximum alignment between the transmitting coil 01 and the receiving coil 40, thereby improving charging efficiency.

[0070] Because the left and right frame frames 22 have a wider structural space, a longer arc circumference, and a larger lateral span (approaching the overall width of the glasses) compared to the temples, ample wiring area is provided for the receiving coil 40. Arranging continuously wound metal conductors within this area significantly increases the number of coil turns and the effective induction area, thereby capturing more magnetic flux and improving charging efficiency. Furthermore, placing the receiving coil 40 in the front frame reduces the risks of space congestion, weight imbalance, and bending / breakage associated with integrating complex coils inside the slender temples. The temples can then focus on functions such as fit, audio output, or touch interaction, resulting in a simpler structure and improved user comfort.

[0071] In one embodiment, the left half-frame assembly 10 includes a first lens 11, a left frame 12, and a left temple 13, wherein the left frame 12 is disposed around the first lens 11 and the left frame 12 is connected to the left temple 13;

[0072] The right half-frame assembly 20 includes a second lens 21, a right side frame 22, and a right temple 23. The right side frame 22 is arranged around the second lens 21 and is connected to the right temple 23. The left side frame 12 and the right side frame 22 are connected by the intermediate connecting structure 30.

[0073] The receiving coil 40 is located inside the left temple 13 and the right temple 23.

[0074] refer to Figure 4 The left frame 12 surrounds the outer periphery of the first lens 11; the right frame 22 surrounds the outer periphery of the second lens 21. The left frame 12 is connected to the left temple 13, and the right frame 22 is connected to the right temple 23, forming a complete frame that can be worn with the ear attached via the bridge of the nose.

[0075] In this embodiment, the receiving coil 40 is disposed inside the temple. For example, after the metal conductor is led out from the starting end, it is first spirally wound along the inner channel or interlayer of the left temple 13 to form the left induction segment; it then extends laterally to the right side through an inner channel of the left frame 12 and a pre-set wire channel inside the intermediate connecting structure 30; it continues to be wound along the corresponding path of the right temple 23 to form the right induction segment; finally, it returns to the opposite end of the starting end through an inner channel of the right frame 22 and the intermediate connecting structure 30, forming a closed loop coil circuit.

[0076] In AR glasses, the front frame area typically integrates optical modules such as cameras and sensors. Positioning the receiving coil 40 within the left and right temples 23 reduces electromagnetic interference and structural conflicts, improving the integration and reliability of the optical system. In most charging cases 200 or charging stands, the temples are closer to the charging contact surface (such as the sidewall or top) during charging. Placing the receiving coil 40 in the temples facilitates alignment with the transmitting coil 01 located on the top or side of the charging case 200, improving magnetic coupling efficiency and thus charging efficiency.

[0077] In accordance with the above embodiments, when a user folds or unfolds the temples of the smart glasses 100 and places them into the charging case 200 or a charging stand such as a charging dock, if the temples of the smart glasses 100 are closer to the bottom of the charging dock or the bottom of the charging case 200 relative to the frame, the transmitting coil 01 can be placed at the bottom of the charging dock or the bottom of the charging case 200. However, if the transmitting coil 01 is placed at the bottom when the frame of the smart glasses 100 is closer to the bottom of the charging dock or the bottom of the charging case 200 relative to the temples, the distance between it and the receiving coil 40 inside the temples will be too great, resulting in reduced coupling efficiency. Therefore, the transmitting coil 01 can be placed at the top of the charging dock or the top of the charging case 200 to achieve the minimum distance and maximum alignment between the transmitting coil 01 and the receiving coil 40, thereby improving charging efficiency.

[0078] The solution of placing the receiving coil 40 inside the left temple 13 and the right temple 23 and forming a continuous closed loop through the intermediate connecting structure 30 is suitable for smart glasses 100 products with limited front frame space and relatively sufficient temple structure space. It improves integration and user experience while ensuring high charging efficiency.

[0079] The present invention also proposes a smart glasses component, with reference to Figure 6 The smart glasses 100 described in any one of the above descriptions, and the charging case 200, wherein the charging case 200 has a receiving cavity for accommodating the smart glasses 100, and the charging case 200 includes a transmitting coil 01 disposed in the receiving cavity;

[0080] The charging box 200 outputs electrical energy through the transmitting coil 01 to charge the smart glasses 100.

[0081] In this embodiment, the charging case 200 is provided with a receiving cavity for accommodating the smart glasses 100. The shape of the receiving cavity matches the shape of the smart glasses 100 in the folded state, so as to stably store the smart glasses 100.

[0082] Optionally, the transmitting coil 01 can be disposed on any one or a combination of the inner wall, bottom, and top surface of the accommodating cavity. The transmitting coil 01 is connected to an external power source (such as a USB-C interface) or a built-in power management module to form a wireless charging transmitter. When the smart glasses 100 are placed in the accommodating cavity, the transmitting coil 01 and the receiving coil 40 on the smart glasses 100 form an electromagnetic coupling in space, and can wirelessly transmit electrical energy to the battery inside the glasses through magnetic induction or magnetic resonance.

[0083] Optionally, the area of ​​the transmitting coil 01 is greater than or equal to the area of ​​the receiving coil 40. For example, the transmitting coil 01 can be designed as an elliptical planar spiral structure, covering the main area at the bottom of the entire accommodating cavity, and its equivalent area is greater than that of the receiving coil 40. When the user places the smart glasses 100 into the charging case 200, the transmitting coil 01 can cover the receiving coil 40, forming an electromagnetic coupling with the receiving coil 40 in space, and realizing power transmission through magnetic induction or magnetic resonance. In this way, when the area of ​​the transmitting coil 01 as a magnetic field source is not less than that of the receiving coil 40, it can ensure that the generated alternating magnetic field completely covers the sensing area of ​​the receiving coil 40; avoiding the phenomenon that some receiving coils 40 "cannot capture the magnetic field" due to the transmitting area being too small, and reducing the ineffective sensing area. In addition, even if the smart glasses 100 is laterally offset, rotated, or slightly tilted within the accommodating cavity, the receiving coil 40 can still be in the strong magnetic field area; realizing effective charging even when the position is offset such as "upright, reversed, left-biased, right-biased", etc., significantly improving the user experience.

[0084] Based on the above embodiments, the receiving coil 40 of the smart glasses 100 can be located inside the frame / temple. Taking the receiving coil 40 of the smart glasses 100 located inside the frame as an example, if the frame area of ​​the smart glasses 100 is closer to the bottom of the receiving cavity when folded, the transmitting coil 01 can be located at the bottom of the charging case 200 to align with the receiving coil 40 located within the left frame 12 and right frame 22. Figure 5 As shown, the transmitting coil 01 can be designed according to the space and shape of the bottom of the glasses case, covering the receiving coil 40. Thus, even with a single-coil design, a certain coupling coefficient can be guaranteed regardless of whether the glasses are placed upright or rotated 180 degrees. It is understandable that if the temple area of ​​the smart glasses 100 is closer to the bottom of the housing cavity when folded, the transmitting coil 01 can be placed on the top of the charging case 200 to be closer to the receiving coil 40 located within the left frame 12 and right frame 22. Similarly, if the temple of the smart glasses 100 is closer to the top or side wall of the housing cavity, and the receiving coil 40 is located within the temple, the transmitting coil 01 can be placed on the top or inner side wall of the charging case 200 to ensure minimum coupling distance.

[0085] Alternatively, a dual-sided transmitting coil 01 structure can be adopted, with transmitting coils 01 set at both the bottom and top of the charging box 200. The detection circuit automatically selects the side that is closer to the receiving coil 40 and has stronger coupling for energy output, thereby improving charging compatibility and efficiency.

[0086] In one embodiment, when the smart glasses 100 is placed in the accommodating cavity, the transmitting coil 01 and the receiving coil 40 of the smart glasses 100 are in a magnetically resonant coupled state, so that the charging box 200 can charge the smart glasses 100.

[0087] In this embodiment, the receiving coil 40 and the transmitting coil 01 can achieve wireless charging using magnetic resonance. The transmitting end of the smart glasses 100 may also include a first resonant capacitor. The receiving coil 40 and the first resonant capacitor form an LC resonant circuit, tuned to a preset operating frequency. The output of the receiving coil 40 is connected to a rectifier circuit, a voltage regulator circuit, a filter circuit, and a charging management IC (Charger IC), etc., to convert the received AC power into DC power and then into a safe and suitable voltage level to charge the built-in battery of the smart glasses 100. Correspondingly, the charging box 200 may also include a second resonant capacitor, which, together with the transmitting coil 01, forms a transmitting end LC resonant circuit and is connected to a driving circuit. When an external power supply voltage is applied, the driving circuit excites the transmitting coil 01 to generate an alternating magnetic field.

[0088] In this embodiment, when the smart glasses 100 are placed in the accommodating cavity, the transmitting coil 01 and the receiving coil 40 are in a magnetically resonant coupled state, that is, their LC resonant circuits are tuned to the same resonant frequency, forming a "resonant energy channel" in space to achieve efficient wireless transmission of electrical energy. The transmitting end driving circuit excites the transmitting coil 01 at a preset operating frequency, causing it to generate a high-intensity alternating magnetic field; the LC circuit composed of the receiving coil 40 and the first resonant capacitor matches the transmitting end frequency and enters a resonant state, significantly enhancing the absorption capacity of magnetic field energy. At the same time, even if there is a certain distance or positional offset between the transmitting coil 01 and the receiving coil 40, a high energy transmission efficiency can still be maintained; the energy is transferred to the receiving coil 40 at the receiving end through the coupled magnetic field, and after rectification and voltage regulation, it charges the battery.

[0089] In practical applications, even if the glasses are tilted or not fully aligned with the transmitting coil 01, as long as the receiving coil 40 is within the near-field range of the transmitting coil 01, resonant coupling can be automatically established, initiating the charging process. Since changes in distance or relative position can alter the coupling coefficient and thus affect charging efficiency, the transmitter control system can adaptively adjust the frequency based on the set target voltage and current (i.e., charging voltage and charging current) to output greater power to compensate for the reduced output power caused by positional offset. This allows the smart glasses 100 to achieve efficient wireless charging without precise alignment after being placed in the charging case 200, improving charging convenience and reliability.

[0090] In one embodiment, the charging case 200 includes a cover and a cavity, the cover being disposed on the cavity to form the receiving cavity;

[0091] When the receiving coil 40 is located within the left frame 12 of the left half-frame assembly 10 and the right frame 22 of the right half-frame assembly 20, the transmitting coil 01 is located within the cover body.

[0092] When the receiving coil 40 is located in the left temple 13 of the left half-frame assembly 10 and the right temple 23 of the right half-frame assembly 20, the transmitting coil 01 is located in the cavity.

[0093] In conjunction with the above embodiments, to minimize the distance between the receiving coil 40 and the transmitting coil 01, thereby maximizing the magnetic coupling coefficient and energy transmission efficiency, the position of the transmitting coil 01 can be adaptively adjusted according to the actual distribution position of the receiving coil 40 on the smart glasses 100. When the receiving coil 40 is located within the left frame 12 of the left half-frame assembly 10 and the right frame 22 of the right half-frame assembly 20 (i.e., the front frame area surrounding the first lens 11 and the second lens 21), if the smart glasses 100 is folded and placed into the cavity, its frame area faces upward, close to the cover, and the temples face downward, close to the bottom of the cavity. At this time, since the front structure where the left frame 12 and the right frame 22 are located is relatively close to the cover, the transmitting coil 01 is placed on the inner surface of the cover, directly facing the frame area of ​​the smart glasses 100. When the cover is closed, the transmitting coil 01 and the receiving coil 40 are parallel and aligned, with a small gap and strong magnetic field coupling. Similarly, when the smart glasses 100 are folded and placed into the cavity, with the temple area facing upwards and close to the cover, and the frame facing downwards and close to the bottom of the cavity, the transmitting coil 01 can be placed at the bottom of the cavity.

[0094] When the receiving coil 40 is located inside the left temple 13 and the right temple 23, after the smart glasses 100 are folded and stored, if the temple portion is pressed against the bottom or side wall of the cavity, the transmitting coil 01 is placed inside the bottom or side wall of the cavity so that when the glasses are placed into the storage cavity, the temple area is in close contact with the transmitting coil 01, and the transmitting coil 01 is parallel and aligned with the receiving coil 40 with a small gap, resulting in strong magnetic field coupling. Similarly, if the frame portion is pressed against the bottom or side wall of the cavity after the smart glasses 100 are folded and stored, the transmitting coil 01 is placed on the cover so that when the glasses are placed into the storage cavity, the frame area is in close contact with the transmitting coil 01.

[0095] The transmitting coil 01 is flexibly positioned within the cover or cavity according to the position of the receiving coil 40, taking into full account the three-dimensional spatial relationship of the smart glasses 100 during charging. Through structural coordination and functional adaptation, high coupling efficiency is ensured, thereby improving the charging effect and enhancing the user experience.

[0096] In another embodiment, when the smart glasses 100 are placed in the accommodating cavity, the receiving coil 40 and the transmitting coil 01 are located on the same horizontal plane.

[0097] In this embodiment, a groove can be provided in the cavity of the charging case 200, and the transmitting coil 01 can be placed in the non-grooved area of ​​the cavity. This ensures that when the smart glasses 100 is placed inside, the plane where the receiving coil 40 is located is at the same horizontal height as the plane where the transmitting coil 01 is located inside the charging case 200. The planes of the transmitting coil 01 and the receiving coil 40 are parallel to each other, and they partially overlap or are adjacent in spatial projection, forming an approximately coplanar coupling structure. For example, the transmitting coil 01 can be embedded in the non-grooved area of ​​the cavity, and the embedding depth is less than the groove depth. Thus, assuming that when the smart glasses 100 is placed in the groove, the outer surface of the frame is against the bottom of the groove, and the temples face the cover, the receiving coil 40 needs to be on the same horizontal plane as the transmitting coil 01. That is, the distance of the transmitting coil 01 from the horizontal plane where the bottom of the groove is located is equal to the distance of the receiving coil 40 from the horizontal plane where the outer surface of the frame is located.

[0098] Compared to the traditional "face-to-face" coupling structure where coils are stacked vertically, this solution features a coplanar transmitting coil 01 and receiving coil, reducing the problem of excessive coupling distance caused by thick lenses and housings. The receiving coil 40 is parallel and aligned with the transmitting coil 01, allowing magnetic lines of force to efficiently pass through the opening area of ​​the receiving coil 40, enhancing mutual inductance. Left-right offsets have minimal impact on the laterally extended coil layout, enabling wireless charging without precise alignment and further improving charging reliability.

Compared with the prior art, the beneficial effects of the smart glasses component provided by this invention are the same as those of the smart glasses 100 provided in the above embodiments, and other technical features in the smart glasses component are the same as those disclosed in the methods of the above embodiments, and will not be repeated here.
