[0035] As a new type of wearable device, augmented reality (AR) glasses have increasingly wide application scenarios, including but not limited to fields such as gaming and entertainment, education and training, industrial maintenance, medical assistance, etc. In these application scenarios, AR glasses need to be continuously and stably powered to ensure the normal operation of the device and the user experience.

[0036] In the current design of AR glasses, the power management system usually uses a flexible printed circuit board 300 (Flexible Printed Circuit, FPC) as the main power transmission medium. FPC is widely used in wearable devices due to its thin, light and bendable characteristics. However, there is a problem of excessive power loss in the application of FPC as a power transmission line in AR glasses. Although FPC has good flexibility and is thin and light, its resistance is relatively large. Especially when the power transmission distance is long or the current is large, the power loss caused by the resistance will increase significantly, resulting in a reduction in power transmission efficiency, and thus affecting the battery 400 endurance time and device performance.

[0037] The main external manifestations of excessive power loss mainly include the shortening of the battery 400 endurance time, the increase in device heat generation, and possible performance instability. When users use AR glasses, they may encounter problems such as frequent charging, device overheating, and function limitations due to insufficient power.

[0038] In summary, while the existing power management systems for AR glasses meet the requirements of being lightweight and bendable, they also face the challenge of excessive power loss. This issue directly affects the battery life of the AR glasses 400 and the overall performance. Therefore, it is necessary to improve the power management system to enhance the power transmission efficiency of the smart glasses and thus improve the user experience.

[0039] Embodiments of the present application provide a smart glasses to solve the problem that the existing smart glasses have large power loss, which affects the battery life of the battery 400. The following will be described in conjunction with the attached Figures 1-5 for illustration.

[0040] The smart glasses provided by the embodiments of the present application are electronic devices that can be worn on the human eyes, including but not limited to common AI glasses, camera glasses, XR glasses, audio glasses, Bluetooth glasses, etc. on the market. The smart glasses can be AR glasses, VR glasses or MR glasses in XR glasses. In an alternative embodiment, referring to Figure 1 and Figure 5 as shown, the smart glasses include a frame 100, two temple arms 200 and a flexible printed circuit board 300. The two temple arms 200 are respectively connected to both ends of the frame 100, and the flexible printed circuit board 300 is installed on the temple arms 200. Among them, at least one of the frame 100 and the temple arms 200 includes a conductive part 220, and the conductive part 220 is electrically connected to the flexible printed circuit board 300.

[0041] It can be understood that in this embodiment, by setting at least one of the frame 100 and the temple arms 200 to include a conductive part 220 for conducting electricity, the conductive frame 100 or temple arms 200 can participate in the power transmission as part of the circuit, effectively reducing the large resistance when the FPC is used as a single wire in traditional smart glasses, reducing less heat loss during the circuit transmission process, reducing unnecessary power loss, improving the energy utilization efficiency, thus extending the battery life of the smart glasses, and also reducing the heat generation of the smart glasses during operation, so as to provide a better user experience for users.

[0042] According to an embodiment of the present application, in combination with Figure 1 , Figure 2 and Figure 3 as shown, the temple arm 200 includes a temple arm body 210, the conductive part 220 is arranged inside the temple arm body 210, the temple arm body 210 is an insulating part, and the conductive part 220 is electrically connected to the flexible printed circuit board 300; and / or, the frame 100 includes a frame body 110, the conductive part 220 is arranged inside the frame body 110, the frame body 110 is an insulating part, and the conductive part 220 is electrically connected to the flexible printed circuit board 300.

[0043] In an alternative embodiment, the temple body 210, being the main part of the temple 200, is made of an insulating material, ensuring the safety of the user during wearing and preventing direct current passing through the temple 200 from causing harm to the human body. The conductive part 220 is disposed within the temple body 210 for electrical connection with the FPC, which not only does not affect the aesthetics of the appearance but also ensures stable transmission of electrical signals.

[0044] In another alternative embodiment, the frame body 110 is made of an insulating material to ensure the safety and comfort of wearing. And within the frame body 110, there is a conductive part 220 which is electrically connected to the FPC to achieve the conductive function, and the conductive part 220 can be distributed at different positions of the frame 100 to meet specific functional requirements.

[0045] Exemplarily, the conductive part 220 is made of a highly conductive metal material such as aluminum alloy or titanium alloy. These materials not only have excellent electrical conductivity but also ensure the mechanical strength and corrosion resistance of the frame 100. By strictly testing the conductivity of the conductive part 220, the loss during the transmission of electrical energy can be minimized.

[0046] In an alternative embodiment, referring to Figure 2 and Figure 3 as shown, the temple body 210 and / or the frame body 110 are provided with an installation groove 230, and the conductive part 220 is installed in the installation groove 230.

[0047] In this embodiment, the installation groove 230 provides a fixed position for the conductive part 220, enabling the conductive part 220 to be firmly installed inside the temple 200 or the frame 100, not easily loosening or falling off, ensuring the stability of the connection between the conductive part 220 and the flexible printed circuit board 300, and reducing the risk of signal interruption or function failure caused by poor contact or loosening. Moreover, the installation groove 230 can also provide a certain degree of protection for the conductive part 220, preventing it from being directly impacted or damaged by the external environment and improving the use safety.

[0048] In an alternative embodiment, the conductive part 220 can be integrally formed with the temple body 210 or the frame body 110. The integrally formed design enhances the connection strength between the conductive part 220 and the temple body 210 or the frame body 110, reduces the risk of loosening or breaking caused by long-term use or external environmental factors (such as temperature change, vibration, etc.), improves the structural stability, and is beneficial to maintaining the overall performance and durability of the smart glasses. Exemplarily, the integrally formed processing methods can include injection molding, 3D printing, or precision machining, etc.

[0049] In an alternative embodiment, referring to Figure 1As shown, the conductive part 220 is provided with bumps 221, and the bumps 221 are electrically connected to the exposed copper part of the flexible printed circuit board 300.

[0050] In this embodiment, by setting the bumps 221 at the key positions of the conductive part 220 through precision machining, the bumps 221 have high geometric accuracy and surface finish to ensure good electrical contact with the exposed copper part of the FPC.

[0051] The design of the bumps 221 increases the contact area between the conductive part 220 and the FPC, thereby improving the stability and reliability of the electrical connection, reducing the risk of poor contact or signal attenuation, and ensuring the stable operation of the smart glasses.

[0052] Optionally, by optimizing the shape and size of the bumps 221, the contact resistance can be reduced and the power transmission efficiency can be further improved. For example, the shape of the bumps 221 can be designed as spherical or hemispherical.

[0053] In an alternative embodiment, since air is a poor conductor of electricity, the presence of an air gap will increase the resistance during power transmission, resulting in energy loss. Therefore, the FPC (flexible printed circuit board 300) is flatly and tightly attached to the inner side of the frame 100 or the temple 200 by using high-precision bonding technology, ensuring the close contact between the FPC and the inner side of the frame 100, eliminating or greatly reducing the air gap between the two, which helps to maintain the continuity and stability of power transmission and improve the transmission efficiency.

[0054] In an alternative embodiment, a metal coating is provided at the connection part of at least one of the bumps 221 and the exposed copper part with the other.

[0055] In this embodiment, the metal coating can be formed by gold plating or silver plating. The metal coating has excellent electrical conductivity, can significantly reduce the contact resistance between the bumps 221 and the exposed copper part, helps to reduce the energy loss during power transmission, and improves the power transmission efficiency. On the other hand, the gold plating or silver plating layer has good chemical stability and antioxidant properties, can maintain stable electrical conductivity under harsh environmental conditions, and the metal coating can improve the surface quality of the connection part, making it smoother, corrosion-resistant and wear-resistant, and improving the reliability and durability of the connection.

[0056] In an alternative embodiment, referring to Figure 2 and Figure 3 As shown, the ratio of the cross-sectional area of the conductive part 220 to the cross-sectional area of the temple 200 is greater than or equal to 60%; and / or, the ratio of the cross-sectional area of the conductive part 220 to the cross-sectional area of the frame 100 is greater than or equal to 60%.

[0057] According to the resistance law, when the resistivity and length are constant, the resistance of a conductor is inversely proportional to its cross-sectional area. Therefore, by increasing the cross-sectional area, the resistance can be reduced. The ratio of the cross-sectional area of the exemplary conductive part 220 to the cross-sectional area of the temple 200 or the frame 100 can be 60%, 65%, 70%, 80%, etc., which helps to reduce the resistance and improve the power transmission efficiency.

[0058] In an alternative embodiment, referring to Figure 1 as shown, a battery 400 is installed on the temple 200. The battery 400 is electrically connected to the flexible printed circuit board 300. The battery 400 is connected to other functional modules (such as a display screen, a camera, a sensor, a processor, etc.) through the flexible printed circuit board 300 and the conductive part 220 to supply power to the other functional modules, realizing various functions of the smart glasses.

[0059] Exemplarily, the battery 400 can be a solid-state battery 400 or a fuel cell 400 to improve the energy density of the battery 400 and the battery life of the smart glasses.

[0060] In an alternative embodiment, in combination with Figure 1 and Figure 2 as shown, an installation cavity 240 is provided at one end of the temple 200 away from the frame 100, and the battery 400 is installed in the installation cavity 240.

[0061] In this embodiment, by installing the battery 400 at one end of the temple 200 away from the frame 100, that is, at the end or near the end of the temple 200, the load balance of the front and rear weights of the glasses is achieved, reducing the shaking and discomfort caused by uneven weight distribution, helping to balance the overall weight distribution of the glasses, improving the wearing comfort of the user, and enhancing the user experience.

[0062] The battery 400 is compactly and safely integrated inside the temple 200 of the smart glasses. By optimizing the space design, it is ensured that while the battery 400 provides a stable power supply, it does not increase the overall weight and volume of the smart glasses.

[0063] In an alternative embodiment, referring to Figure 4 as shown, the number of batteries 400 is two, and they are respectively installed on the temples 200 on both sides, further improving the balance performance and wearing comfort of the smart glasses.

[0064] In an alternative embodiment, the smart glasses further include a power management module (not shown in the figure). The power management module is installed on the temple 200 and is arranged close to the battery 400.

[0065] In this embodiment, placing the power management module in a position adjacent to the battery 400 can significantly reduce the transmission distance of power from the battery 400 to the management module, thereby reducing the loss of electrical energy during transmission. The power management module also incorporates an intelligent control algorithm that can dynamically adjust the power distribution according to the actual usage of the device (such as the brightness of the display screen, the working state of the camera, etc.) to optimize the energy utilization efficiency.

[0066] The power management module is connected to the conductive part 220 and the FPC through an optimized circuit design, and is carefully laid out and wired to ensure the efficient transmission of electrical energy; at the same time, it also has good anti-interference performance, which can reduce the impact of electromagnetic interference on the device performance and ensure the efficient and stable transmission of electrical energy.

[0067] In an alternative embodiment, the power management module includes at least one of an overcharge protection circuit, an over-discharge protection circuit, and an over-current protection circuit.

[0068] When the battery 400 is charged to near its maximum capacity, the overcharge protection circuit will automatically cut off the charging current to prevent the battery 400 voltage from being too high; when the battery 400 power level drops to a certain level, the over-discharge protection circuit will be triggered to prevent the device from continuing to draw electrical energy from the battery 400 to prevent the internal structure of the battery 400 from being damaged or the capacity from permanently decreasing due to the battery 400 voltage being too low; the over-current protection circuit can quickly cut off the power supply or adjust the output current when detecting an abnormal increase in current to protect the device from damage.

[0069] Exemplarily, the performance comparison between the smart glasses of the embodiments of the present application and traditional smart glasses is as follows:

[0070] Item Traditional Design This Application Degree of Improvement Power Loss High Low Significantly Reduced Battery Life Shorter Longer Significantly Improved Operating Temperature Higher Lower Effectively Controlled Power Management Efficiency Average High Efficiency Significantly Improved

[0071] By integrating at least one of an overcharge protection circuit, an over-discharge protection circuit, and an over-current protection circuit, the power management module of the smart glasses not only improves the energy utilization efficiency but also brings a safer and more convenient user experience to the user.

[0072] The power management system of traditional smart glasses usually relies on FPC and complex wire connections. The smart glasses provided by the embodiments of the present application include a frame 100, two temple arms 200, and a flexible printed circuit board 300. The two temple arms 200 are respectively connected to both ends of the frame 100, and the flexible printed circuit board 300 is installed on the temple arms 200. Among them, at least one of the frame 100 and the temple arms 200 includes a conductive part and is electrically connected to the flexible printed circuit board 300. By designing the frame 100 or the temple arms 200 to include a conductive part, the frame 100 or the temple arms 200 not only play a supporting and protecting role, but also become part of the circuit system, playing the function of conducting the circuit, simplifying the circuit structure, effectively reducing the resistance of the flexible printed circuit board 300 as a single wire, thereby reducing the loss during the power transmission process and improving the battery life performance of the smart glasses.
