[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 3 As shown, an embodiment of the present invention provides a kind of smart glasses, including a temple assembly 2, a frame assembly 3 and a shaft structure 1 for connecting the temple assembly 2 and the frame assembly 3, the shaft structure 1 including: a first connecting member 11, for being arranged inside the temple shell 21 of the temple assembly 2, the first connecting member 11 including a first connecting portion 111, and a threaded hole is provided inside the temple shell 21 to connect the first connecting portion 111 and the temple shell 21 by a first screw 112 passing through the first connecting member 11 and the threaded hole; a second connecting member 12, for being arranged inside the frame assembly 3, the second connecting member 12 including a mounting post 121 and a second connecting portion 122, the second connecting portion 122 being rotatably connected to the first connecting portion 111, so that the temple assembly 2 is rotatably opened and closed relative to the frame assembly 3; a fastener 13, the fastener 13 is located on the side of the second connecting portion 122 away from the first connecting portion 111, and the fastener 13 extends into the mounting post 121 after passing through the frame assembly 3 to be connected to the mounting post 121.

[0032] In the smart glasses provided by the embodiment of the present invention, the first screw 112 of the first connecting member 11 is hidden in the temple shell 21, and the fastener 13 of the second connecting member 12 is hidden in the frame assembly 3. This hidden installation strategy makes the connecting components invisible from the outside of the smart glasses, thereby improving the product's aesthetics and user visual experience.

[0033] In an embodiment of the present invention, the first connecting member 11 is designed to be tightly integrated with the temple assembly 2, and it is placed inside the temple housing 21. The key part of the first connecting member 11 is the first connecting portion 111, which is provided with a screw hole, which is aligned with the threaded hole inside the temple housing 21. The two are connected by a first screw 112, ensuring a stable mechanical connection between the temple assembly 2 and the first connecting member 11, while keeping the appearance of the temple neat because the screw used for fixing is not exposed. The second connecting member 12 is installed inside the frame assembly 3 and consists of a mounting post 121 and a second connecting portion 122. The second connecting portion 122 is rotatably connected to the first connecting portion 111 of the first connecting member 11 through a circular shaft, forming a hinge effect, so that the temple can be smoothly opened and closed. One end of the mounting post 121 is connected to the second connecting portion 122, and the other end is reserved with a threaded hole for subsequent connection with the fastener 13. In this embodiment, the fastener 13 is a second screw that penetrates from the outside of the frame assembly 3 and is threadedly engaged with the mounting post 121 of the second connecting member 12, thereby securing the second connecting member 12 in place within the frame assembly 3. This design ensures that the appearance of the frame assembly 3 is not affected, as the head of the fastener 13 is concealed by the frame cover 32, preserving the overall aesthetics.

[0034] like Figure 3 、 Figure 4 As shown, specifically, the frame assembly 3 includes a frame housing 31, which is covered with a frame cover plate 32 that matches the shape of the frame housing 31. The fastener 13 passes through the frame housing 31 and extends into the mounting post 121. The stopper head of the fastener 13 is located on the side of the frame housing 31 away from the mounting post 121, and the frame cover plate 32 is located outside the stopper head. The frame assembly 3 is composed of the frame housing 31 and the frame cover plate 32, wherein the frame cover plate 32 is designed to completely match the shape of the frame housing 31, thereby ensuring a neat and consistent appearance of the frame assembly 3. The fastener 13 is designed to penetrate from the outside of the frame housing 31, pass through the frame housing 31, and then extend into the mounting post 121 of the second connecting member 12, thereby securing the second connecting member 12 inside the frame housing 31. The frame cover 32 is designed to be able to cover the outside of the limit head of the fastener 13. In this way, not only the limit head is covered, making the appearance of the frame assembly 3 more complete and without exposed fasteners 13 affecting the appearance, but also further strengthens the fixation to prevent it from loosening due to external force during use, thereby improving the durability of the smart glasses.

[0035] like Figure 4As shown, specifically, both ends of the frame housing 31 are provided with connecting portions 311, which are connected to the two temple assemblies 2 through the two connecting portions 311. The connecting portion 311 has a mounting cavity 311a, a mounting base 311b, and a mounting opening 311c. The mounting opening 311c and the mounting base 311b are respectively located at the two ends of the mounting cavity 311a. The mounting post 121 is inserted into the mounting cavity 311a through the mounting opening 311c. The fastener 13 passes through the mounting base 311b and is connected to the mounting post 121. The frame housing 31 is provided with a connecting portion 311 at each end. This design purpose is to connect with the temple assemblies 2 on both sides to ensure the overall structural stability and symmetry of the glasses. Each connecting portion 311 includes an installation cavity 311a therein, which has sufficient space to accommodate the installation column 121 of the second connecting member 12. At the same time, the structure of the connecting portion 311 also includes a mounting base plate 311b and a mounting opening 311c, wherein the mounting opening 311c is located at one end of the frame shell 31, and the mounting base plate 311b is at the other end, forming a closed chamber from the opening to the base plate.

[0036] During installation, the mounting post 121 of the second connector 12 is inserted into the mounting cavity 311a through the mounting opening 311c. The fastener 13 then passes through the mounting base plate 311b of the frame housing 31 from the outside and extends into the mounting post 121. The mounting post 121 is secured within the mounting cavity 311a, thereby achieving a secure connection between the second connector 12 and the frame assembly 3. The mounting base plate 311b is provided with a through hole that matches the fastener 13, ensuring that the fastener 13 can smoothly pass through and enter the mounting post 121. Furthermore, the size and position of the through hole are precisely calculated to ensure that the fastener 13 is fully aligned with the mounting post 121 during installation, thus preventing deviation during installation.

[0037] Through the above design, the mounting post 121 of the second connecting member 12 is firmly fixed in the mounting cavity 311a of the frame shell 31. This fixing method greatly enhances the structural strength of the connecting part 311. Even when the temples are frequently opened and closed or subjected to external impact, the stability of the connection between the second connecting member 12 and the frame assembly 3 can be maintained, reducing the risk of loosening or damage of the hinge structure 1.

[0038] like Figure 1As shown, specifically, the second connecting portion 122 includes a partition plate 122a and a connecting protrusion 122b. The connecting protrusion 122b is configured for rotational connection with the first connecting portion 111. The mounting post 121 is mounted on the side of the partition plate 122a away from the connecting protrusion 122b. The partition plate 122a is adapted to fit within the mounting opening 311c to block the mounting opening 311c. When designing the hinge structure 1 of the smart glasses, the second connecting portion 122 of the second connecting member 12 is conceived as a combination of the partition plate 122a and the connecting protrusion 122b. The partition plate 122a primarily functions as a physical barrier between the mounting post 121 and the connecting protrusion 122b. Furthermore, it is adapted to the size and shape of the mounting opening 311c. Once the mounting post 121 is inserted into the mounting cavity 311a and secured by the fastener 13, it blocks the mounting opening 311c, forming a closed mounting cavity 311a, thereby enhancing the structural stability and safety. Separator plate 122a blocks mounting opening 311c. Combined with frame cover 32, this eliminates visible screws or connectors on the exterior of frame assembly 3, maintaining a clean and aesthetically pleasing appearance for the smart glasses and enhancing their visual appeal. Separator plate 122a tightly fits within mounting opening 311c, forming a closed space that effectively prevents dust and moisture from entering the interior of hinge structure 1, protecting internal components from environmental damage and extending the lifespan of the smart glasses.

[0039] The mounting post 121 is mounted on the side of the partition plate 122a away from the connecting protrusion 122b. It mates with the fastener 13, which passes through the mounting base plate 311b and then threads onto the mounting post 121, securing the second connecting member 12 within the frame housing 31. The connection between the mounting post 121 and the partition plate 122a is designed to be secure, preventing loosening or displacement during long-term use, thereby ensuring the stability and reliability of the hinge structure 1. The connection between the mounting post 121 and the partition plate 122a is designed to be secure, preventing loosening or displacement during long-term use, thereby ensuring the stability and reliability of the hinge structure 1. The connecting protrusion 122b is designed to match the shape of the first connecting portion 111 and protrude from the other side of the partition plate 122a. When the first connecting portion 111 and the second connecting portion 122 are rotatably connected via the circular shaft, the connecting protrusion 122b forms a hinge with the first connecting portion 111, allowing for smooth opening and closing of the temple assembly 2. The surface of the connecting protrusion 122b is specially treated to improve its wear resistance and smoothness during rotation, ensuring the long-term durability of the shaft connection and the user's comfortable experience during use.

[0040] like Figure 5As shown, specifically, the smart glasses also include a sealant sandwiched between the partition plate 122a and the mounting opening 311c to prevent external liquids and dust from entering the mounting cavity 311a through the mounting opening 311c. In the design of the hinge structure 1 of the smart glasses, a sealing ring is specifically incorporated between the partition plate 122a and the mounting opening 311c to further enhance the dust and water resistance of the frame assembly 3. When the mounting post 121 of the second connector 12 is installed into the mounting cavity 311a of the frame assembly 3 through the mounting opening 311c and is connected to the mounting post 121 from the outside through the mounting base plate 311b by the fastener 13, the sealing ring is compressed between the partition plate 122a and the mounting opening 311c, forming an effective sealing barrier. The sealing ring is typically made of highly elastic waterproof materials, such as silicone or nitrile rubber. These materials have excellent elasticity and durability, and can adapt to the slight displacement of the hinge during multiple opening and closing processes to maintain a sealing effect. The inner side of the sealing ring fits tightly against the partition plate 122a, while its outer side forms close contact with the edge of the mounting opening 311c. This effectively prevents external liquids and dust from entering the mounting cavity 311a through the mounting opening 311c, protecting the internal electronic components and mechanical structure from environmental damage. The addition of the sealing ring significantly enhances the sealing performance of the hinge structure 1, effectively preventing dust and liquids from entering the mounting cavity 311a. This is crucial for extending the life of the smart glasses and ensuring the proper functioning of their internal components.

[0041] Specifically, the hinge structure 1 also includes a first elastic member 14, which is disposed between the second connecting portion 122 and the frame assembly 3 to provide elastic force compensation when the temple assembly 2 rotates relative to the frame assembly 3. One end of the first elastic member 14 is mounted on the second connecting portion 122, and the other end of the first elastic member 14 is configured to abut the frame assembly 3. In the design of the hinge structure 1 of the smart glasses, the first elastic member 14, typically a spring or similar elastic element, is specifically introduced to optimize the rotational performance between the temple assembly 2 and the frame assembly 3. The first elastic member 14 is disposed between the second connecting portion 122 and the frame assembly 3, playing a key role in providing elastic force compensation.

[0042] Specifically, one end of the first elastic member 14 is mounted on the partition plate 122a of the second connecting portion 122, and the other end is designed to abut against the inner wall of the frame assembly 3 or a specially arranged abutment member (such as a spring seat). When the temple assembly 2 is opened or closed relative to the frame assembly 3, the first elastic member 14 is compressed or stretched during the movement of the temple assembly 2, thereby generating a feedback force. The effect of this force is that when the temple is opened, the compression of the first elastic member 14 generates a reverse elastic force, which can enable the temple assembly 2 to match the head circumference of different users during use, and is not easy to loosen or slip, providing a better wearing experience.

[0043] Specifically, the first elastic member 14 includes a spring component 141 and a pressure block component 142, the frame assembly 3 includes a frame shell 31, one end of the spring component 141 is connected to the pressure block component 142, and the other end of the spring component 141 is used to abut against the frame shell 31; wherein, the pressure block component 142 includes a limit block 142a and a plug-in block 142b, the plug-in block 142b is inserted on the second connecting part 122, and the limit block 142a is limited on the side of the second connecting part 122 away from the first connecting part 111; the outer peripheral surface of the plug-in block 142b is surrounded by two oppositely arranged plug-in planes 142b1 and two oppositely arranged plug-in arc surfaces 142b2, and the two plug-in arc surfaces 142b2 are located at both ends of the two plug-in planes 142b1.

[0044] In the design of the hinge structure 1 of the smart glasses, the first elastic member 14 is mainly realized through the cooperation of the spring component 141 and the pressure block component 142. One end of the spring component 141 is connected to the limit block 142a of the pressure block component 142, and the other end is in contact with the inner wall of the frame shell 31 to form an elastic connection. This design ensures that when the temple assembly 2 rotates relative to the frame assembly 3, the spring component 141 can provide appropriate elastic force compensation, so that the temple can move smoothly according to user needs when opening or closing, and remain stable in the predetermined position. The design of the pressure block component 142 is particularly ingenious. It consists of two parts: the limit block 142a and the plug-in block 142b. The plug-in block 142b is connected to a specific structure (such as a reserved slot) on the second connecting part 122 in a plug-in manner. This plug-in structure design not only simplifies the assembly process, but also ensures a stable connection between the first elastic member 14 and the second connecting part 122. The limiting block 142a is provided on a side of the second connecting portion 122 away from the first connecting portion 111, and serves to limit and stabilize the pressing block component 142, preventing the pressing block component 142 from falling off the second connecting portion 122 during the opening and closing of the temple. The outer peripheral surface of the plug-in block 142b is designed to be surrounded by two opposing plug-in planes 142b1 and two opposing plug-in arcuate surfaces 142b2. This structural design allows the plug-in block 142b to be more accurately plugged into the second connecting portion 122. At the same time, the presence of the two plug-in arcuate surfaces 142b2 can reduce the contact area between the plug-in block 142b and the second connecting portion 122, thereby reducing frictional resistance during rotation, making the opening and closing of the temple assembly 2 smoother and improving the wearing comfort of the user.

[0045] like Figure 6As shown, specifically, the plug-in block 142b is strip-shaped, and the second connecting portion 122 is provided with a strip-shaped hole that matches the shape of the plug-in block 142b; the limiting block 142a includes a limiting flange 142a1, at least a portion of the outer circumference of the limiting flange 142a1 protruding from the outer circumference of the strip-shaped hole; along the extension and contraction direction of the spring component 141, the length of the plug-in block 142b is greater than the length of the limiting flange 142a1. In the design of the hinge structure 1 of the smart glasses, in order to achieve efficient connection and stable operation between the first elastic member 14 and the second connecting portion 122, the plug-in block 142b is designed as a strip-shaped structure. This shape matches the strip-shaped hole in the second connecting portion 122, ensuring that the plug-in block 142b can be accurately inserted into the strip-shaped hole, thereby firmly connecting to the second connecting portion 122. The design of the strip-shaped hole makes the installation process of the plug-in block 142b simple and stable, reduces the loosening or damage of components due to improper assembly, and also facilitates subsequent maintenance and replacement. The limit block 142a, as part of the pressure block component 142, is designed to include a limit flange 142a1. The outer peripheral surface of the limit flange 142a1 partially protrudes from the outer peripheral surface of the strip-shaped hole. The purpose of this design is that when the pressure block component 142 is installed on the second connecting portion 122, the limit flange 142a1 can effectively limit the movement range of the pressure block component 142, preventing the pressure block component 142 from unnecessary displacement or rotation during the opening and closing process of the temple assembly 2, thereby ensuring the stability and durability of the operation of the first elastic member 14.

[0046] Furthermore, the length of the plug block 142b in the direction of extension and contraction of the spring member 141 is designed to be greater than the length of the limiting flange 142a1. This length difference ensures that the limiting flange 142a1 provides sufficient stable support when the spring member 141 is compressed or stretched, preventing the entire plug block 142b from moving due to the spring force, which would affect the operating efficiency and service life of the first elastic member 14. Furthermore, the design of the limiting flange 142a1 also ensures more accurate positioning of the pressure block member 142 within the frame housing 31, providing a more stable operating environment for the spring member 141.

[0047] Specifically, the fastener 13 is a second screw, and the mounting post 121 is provided with an internal threaded hole, and the second screw is threadedly connected to the internal threaded hole to fix the second connecting member 12 to the frame assembly 3; wherein, the length of the mounting post 121 is greater than the length of the fastener 13. In the design of the rotating shaft structure 1 of the smart glasses, the second connecting member 12 is fixed to the frame assembly 3 using a second screw as the fastener 13. The mounting post 121 is designed to have an internal threaded hole so that the second screw can be threadedly connected thereto. This connection method not only ensures the stable fixation of the second connecting member 12 on the frame assembly 3, but also provides good disassembly and maintainability. In order to ensure the correct positioning and firm connection of the second screw during the installation process, the length of the mounting post 121 is designed to be greater than the length of the fastener 13 (second screw).

[0048] This means that when the second screw is fully screwed into the internal threaded hole of the mounting post 121, its head will not be flush with the top of the mounting post 121. Instead, a portion of the second screw's length will be hidden inside the mounting post 121. This not only enhances the reliability of the connection, but also prevents the second screw's head from being directly exposed to the outside of the rotating shaft structure 1, affecting the appearance design and user experience of the smart glasses. During the actual assembly process, the second screw is inserted from the outside of the frame housing 31, and its threads mate with the internal threaded hole of the mounting post 121, ultimately securing the second connector 12 to the inside of the frame housing 31. This design ensures a tight connection between the second connector 12 and the frame housing 31, maintaining stability even with frequent opening and closing of the temples, and reducing the risk of loosening or falling off.

[0049] Specifically, the fastener 13 includes a limiting end and a free end. The free end passes through the frame assembly 3 and then engages with the mounting post 121. The limiting end is limited on the frame assembly 3. In the design of the rotating shaft structure 1 of the smart glasses, the fastener 13 is designed to have a special structure with a limiting end and a free end. The free end is designed to be able to pass through a specific opening of the frame assembly 3, such as a preset screw hole, while the limiting end has a larger diameter or a special shape to prevent the fastener 13 from completely passing through the opening, thereby forming an effective limit on one side of the frame assembly 3. During the assembly process, the free end first passes through the opening of the frame assembly 3 and then engages with the mounting post 121 of the second connecting member 12. The mounting post 121 is provided with a slot that matches the shape of the free end. When the free end is inserted into the slot and rotated, a locking state that prevents loosening is formed, thereby fixing the second connecting member 12 to the frame assembly 3. At the same time, the limiting end forms a limit on the other side of the frame assembly 3 to prevent the fastener 13 from withdrawing when subjected to a reverse force, thereby ensuring the stability of the connection.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] The first connecting member 11 and the second connecting member 12 are fixed by the first screw 112 and the second screw, thereby achieving a stable connection between the temple assembly 2 and the frame assembly 3. At the same time, the limiting design of the fastener 13 ensures the stability of the components during use, reduces the risk of loosening due to mechanical vibration or external force impact, and enhances the reliability and service life of the overall structure. The integrated design of the mounting column 121 and the second connecting member 12, as well as the clamping method of the fastener 13, not only simplifies the assembly process, but also optimizes the internal space layout of the smart glasses, making the shaft structure 1 more compact, leaving more space for other functional modules (such as batteries, sensors, etc.) inside the frame assembly 3, and helping to achieve a lightweight and miniaturized design of the smart glasses. The sealing design between the partition plate 122a and the mounting opening 311c effectively prevents external liquids and dust from entering the mounting cavity 311a through the mounting opening 311c, thereby ensuring the safety of the electronic components inside the smart glasses, improving the waterproof and dustproof level of the product, and enhancing the adaptability and reliability of outdoor use.

[0052] The introduction of the first elastic member 14, especially the coordinated use of the spring member 141 and the pressure block member 142, enables the temple assembly 2 to obtain smooth elastic force compensation when rotating relative to the frame assembly 3, thereby avoiding the rapid sagging or swinging of the temple due to its own weight or external force, and improving the user's comfort and control accuracy when wearing. By hiding the fastener 13, the first elastic member 14 and other components inside, and setting the frame cover 32 on the outside, not only the simplicity and beauty of the appearance of the smart glasses are maintained, but also the discomfort or damage risk that the exposed components may bring to the user is avoided, thereby improving the overall user experience. The adaptive design of the bar hole and the plug-in block 142b, as well as the threaded connection between the second screw and the internal threaded hole of the mounting column 121, simplifies the assembly process, reduces the difficulty of assembly, and also facilitates subsequent maintenance and component replacement, providing users with a more convenient service experience and reducing the maintenance cost of the product. By controlling the length of the limit block 142a and the compression stroke of the spring component 141, the elastic force provided by the first elastic member 14 can be precisely adjusted to ensure that the temple assembly 2 can obtain an appropriate damping feeling when opening and closing. It is neither too tight to cause a sense of oppression to the user, nor too loose to cause the temple to be unable to remain stable, thereby improving the wearing comfort and the overall user experience.

[0053] The use of standard parts (such as the first screw 112 and the second screw) as fasteners 13, as well as universal snap-on and threaded connection methods, is not only conducive to mass production and reduces customization costs, but also improves assembly efficiency, providing strong technical support for the large-scale production of smart glasses. In summary, the design of the smart glasses shaft structure 1 provided by the utility model, by optimizing the structure of the connector and the fastener 13, and introducing the first elastic member 14 and the seal, not only improves the mechanical performance and reliability of the smart glasses, but also optimizes the user experience, achieves lightweight, waterproof and dustproof, aesthetic and cost-effective product design, demonstrates the innovation and practicality of the product design, and provides a solid technical foundation for the high-quality manufacturing and market competitiveness of smart glasses.
