Description

Technical Field

[0001] This application relates to the technical field of wearable smart devices, and more particularly to a waterproof hinge for smart glasses and smart glasses. Background Technology

[0002] With the rapid development of smart wearable technology, smart glasses such as AI glasses and VR glasses are becoming increasingly popular. Their functional integration is constantly improving, and they typically need to simultaneously possess core functions such as image acquisition (taking photos / videos), data storage and processing, and audio output (sound output). To achieve these functions, smart glasses need to integrate various electronic components such as camera modules, processors, memory, speakers, and batteries within the frame, temples, and other structures. The signal transmission and circuit connection between the frame and temples are generally achieved using flexible printed circuit boards (FPCs) connected through the glasses' hinges.

[0003] Specifically, to allow the FPC to pass through the hinge structure and complete the circuit connection between the frame and temples, holes or gaps adapted for FPC wiring need to be made in the hinge body and corresponding assembly positions. However, in actual use scenarios, smart glasses need to be worn on the user's head for extended periods, inevitably coming into contact with liquids or moisture such as sweat, rain, and ambient humidity. Since the holes / gaps at the hinge are designed to accommodate FPC installation, their sealing performance is limited by the structure and cannot be completely closed. This allows sweat to easily seep from the user's scalp to the hinge surface, and rainwater or other liquids in the environment may also directly splash onto the hinge area. These liquids can easily seep into the frame and temples through the assembly gaps between the holes and the FPC. The electronic components inside the frame and temples are sensitive to moisture. Once liquid seeps in, it can not only cause short circuits and corrosion, but also lead to abnormal signal transmission and functional failure. In severe cases, it can directly cause permanent damage to electronic components, significantly reducing the lifespan and reliability of the smart glasses. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a waterproof hinge for smart glasses and smart glasses, which can solve the problem of easy water ingress at the hinge connection of smart glasses in related technologies.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a waterproof hinge for smart glasses is provided, including a first hinge support, a second hinge support, a first sealing plug, and a second sealing plug. The first hinge support includes a first connecting seat and a first hinge portion connected together. The first connecting seat is used to connect the temple and has a first through hole for communicating between the inner and outer regions of the temple. The second hinge support includes a second connecting seat and a second hinge portion connected together. The second connecting seat is used to connect the frame and has a second through hole for communicating between the inner and outer regions of the frame. The second hinge portion is hinged to the first hinge portion. The first sealing plug is configured to cooperate with the first through hole and has a first wire hole that allows a flexible conductor to pass through. The first sealing plug is installed in the first through hole. The second sealing plug is configured to cooperate with the second through hole and has a second wire hole that allows a flexible conductor to pass through. The second sealing plug is installed in the second through hole.

[0006] The waterproof hinge of this application embodiment achieves an organic unity of structural sealing and functional practicality through the synergistic design of double hinge supports and double sealing plugs. Its core beneficial effects are significant: Firstly, the precise and tight fit of the two sealing plugs with the corresponding perforation inner wall and the surface of the flexible connector conductor forms a double sealing barrier, effectively preventing sweat, rainwater, and ambient moisture from seeping into the frame or temple through the perforation gap at the hinge. This avoids problems such as short circuits, corrosion, malfunction, or permanent damage to internal electronic components due to water exposure, significantly improving the waterproof performance, reliability, and lifespan of smart glasses. On the one hand, the overall structure is simple and compact, without complex additional parts, making it easy to process and assemble and highly adaptable. The wire passage hole of the sealing plug can be flexibly adjusted according to the size of the flexible connector conductor. The hinge support structure can adapt to different specifications of frames and temples, and can be widely used in various smart glasses products such as AI glasses and VR glasses. At the same time, the sealing structure and the hinge rotation function do not interfere with each other, which not only ensures the stability of the circuit connection, but also does not affect the smooth operation of unfolding, wearing and folding the smart glasses. It can also avoid wear on the flexible connector conductor during assembly, reduce user maintenance costs, and significantly enhance the product's market competitiveness.

[0007] In one embodiment, the first through hole extends from the inside to the outside along the penetrating direction. The diameter of the first through hole is constricted. As the first sealing plug is inserted deeper into the first through hole, the diameter of the first through hole is squeezed and constricted to a smaller size. And / or, extending from the inside to the outside along the through direction of the second perforation, the diameter of the second perforation is constricted, and the deeper the second sealing plug is inserted into the second perforation, the smaller the diameter of the second wire hole is squeezed and constricted.

[0008] In this embodiment, a constricting first and / or second perforation is used. The resulting conical inner cavity provides a wedge-shaped positioning space for the sealing plug. After the elastic first and / or second sealing plugs are inserted, the constricting slope of the perforation exerts a radial compressive force on the sealing plug, causing the outer wall of the sealing plug to fit tightly against the inner wall of the perforation. Simultaneously, the inner wall of the wire hole of the sealing plug also exerts a radial compressive force on the flexible conductor, further reducing the gap between the sealing plug and the conductor, achieving a passive compression sealing effect. Compared to a perforation of equal diameter, this structure can significantly improve the tightness of the sealing interface. In addition, the constricting structure with a wider inner diameter and a narrower outer diameter forms a limiting step in the aperture direction. After the sealing plug is inserted from the inner cavity side, its maximum outer diameter portion is blocked by the constricting slope of the perforation, preventing it from falling out to the external environment. At the same time, when the glasses rotate, vibrate, or are pulled by external forces, this limiting structure can effectively restrict the axial displacement of the sealing plug, avoiding sealing failure caused by displacement.

[0009] In one embodiment, the first sealing plug includes a first insert portion that is inserted into the first perforation and extends from the inside to the outside along the through direction of the first perforation. The outer diameter of the first insert portion is tapered. As the first insert portion is inserted deeper into the first perforation, the diameter of the first wire hole is squeezed and contracted to a smaller size. And / or, the second sealing plug includes a second insert portion that is inserted into the second perforation and extends from the inside to the outside along the through direction of the second perforation. The outer diameter of the second insert portion is tapered, and the diameter of the second wire hole is squeezed and contracted to a smaller size as the second insert portion is inserted deeper into the first perforation.

[0010] In this embodiment, a constricting, cone-shaped first and / or second insert portion is used to form a wedge-shaped inlay structure with the first and / or second perforations. After the first and / or second sealing plugs are inserted, the constricting slope of the perforation generates a radial compressive force across the entire area of ​​the insert portion along the extension direction of the perforation. This causes the inner wall of the through-hole of the insert portion to exert a radial compressive force on the flexible connector conductor, further reducing the gap between the sealing plug and the conductor, extending the sealing path, and enhancing the sealing effect. Furthermore, the cone-shaped insert portion also has the advantage of convenient and quick insertion and installation.

[0011] In one embodiment, the first sealing plug includes a first insertion portion and a first limiting portion connected together. The first insertion portion is inserted into the first through hole, and the first limiting portion abuts against the inner end face of the first connecting seat to form an annular sealing structure. And / or, the second sealing plug includes a connected second insertion portion and a second limiting portion, the second insertion portion being inserted into the second perforation, and the second limiting portion abutting against the inner end face of the second connecting seat to form an annular sealing structure.

[0012] In this embodiment, the connection between the limiting part and the insertion part forms a natural stepped surface. During assembly, the inner end face of the connector is used as the positioning reference. The abutting action of the limiting part ensures that the insertion part is embedded in the perforation at a consistent depth, avoiding problems such as insufficient sealing due to shallow insertion or compression of the flexible conductor due to excessive insertion. At the same time, the tight fit between the stepped surface and the end face of the connector can further block the path of liquid penetration from the end face gap. Combined with the three-dimensional sealing system formed by the end face sealing, the waterproof protection level is greatly improved, further reducing the risk of damage to electronic components caused by liquid infiltration.

[0013] In one embodiment, the through-hole extends along an arc, and the perpendicular bisectors of the two ends of the first through-hole form an angle with each other.

[0014] In this embodiment, the conductor's smooth turning is achieved through the arc trajectory of the first through hole, solving the stress concentration and breakage risk caused by the forced bending of the conductor in a straight through hole, extending the service life of the flexible conductor, and precisely guiding the flexible conductor's direction to avoid misalignment or breakage within the hinge, thus ensuring the stability of circuit signal transmission. On the other hand, the arc design is highly compatible with the mounting position on the side of the hinge support, making full use of narrow spaces to arrange wiring channels, avoiding an increase in hinge volume, meeting the lightweight requirements of smart glasses, and the matching design of the arc-shaped sealing plug and the arc through hole ensures that the turning structure does not affect the sealing performance.

[0015] In one embodiment, the first hinge portion and the second hinge portion are configured such that one includes two spaced-apart first hinge bosses and the other includes a second hinge boss. The two first hinge bosses are respectively hinged to two opposite sides of the second hinge boss. The first hinge boss and the second hinge boss are interference-fitted to form a damping structure.

[0016] In this embodiment, the structure of a single boss encased by two bosses significantly improves the deformation resistance and rotational stability of the hinge, avoiding damage caused by concentrated stress in traditional hinge structures, extending the hinge's lifespan, and ensuring smooth and precise operation when the smart glasses are unfolded and folded, thus enhancing the user experience. On the other hand, the nesting gap provides dedicated routing space for the flexible conductor, reducing the risk of wear and ensuring the stability of circuit signal transmission. Furthermore, this structural design eliminates the need for additional protective components; the optimization of the boss layout alone achieves a dual improvement in stability and protection, simplifying the overall hinge structure and reducing manufacturing costs. In addition, the interference fit between the first and second hinge bosses forms a damping structure, preventing relative free rotation between the first and second hinge parts and maintaining the stability of the smart glasses' temples in unfolded or folded states.

[0017] In one embodiment, a third through hole is formed between the two first hinge bosses, and a fourth through hole is provided on the second hinge boss. The first through hole, the third through hole, the fourth through hole and the second through hole are connected to form a connected wire channel. The two first hinge parts and the two second hinge parts are respectively connected by independent screws. The two screws are spaced apart in the fourth through hole to form a vertical space.

[0018] In this embodiment, the wiring channel completely encloses the flexible conductor from the inner cavity of the temple to the inner cavity of the frame within the hinge's internal structure, preventing the conductor from being exposed to the hinge gap or the external environment. Specifically, the flexible conductor is guided and turned by the arc-shaped structure in the first through hole, and is positioned by the second hinge boss when entering the third through hole and passing through the fourth through hole. Finally, it enters the inner cavity of the frame through the second through hole, following a fixed channel throughout. Even when the hinge rotates, the flexible conductor only moves slightly within the channel, without any offset, entanglement, or friction with external components. Since the third and fourth through holes rotate synchronously with the hinge (the first hinge boss rotates, driving the third through hole, and the second hinge boss rotates, driving the fourth through hole), and both remain coaxial, the wiring channel will not misalign or deform during rotation. The conductor only makes adaptive bending and fine adjustments with the rotation of the channel, avoiding the conductor being pulled or squeezed due to channel offset, thus ensuring the continuity and stability of circuit signal transmission. The two second hinge parts on both sides are hinged to the two sides of the first hinge part by independent screws, keeping the fourth through hole in the middle clear and avoiding contact interference with the flexible conductor inside the fourth through hole. At the same time, the structure with hinges on both sides has the advantages of good stability and high durability.

[0019] In one embodiment, the diameter of the third and fourth through holes is larger than the outer diameter of the flexible conductor, so that the flexible conductor can bend or stretch adaptively in the third and fourth through holes during the relative rotation of the first and second hinge supports. The opening angle of the fourth through hole near the third through hole relative to the hinge axis is 0 to 90 degrees.

[0020] The purpose of the third and fourth through holes is to provide a path for the flexible connector conductor to pass through. After passing through, the flexible connector conductor can be hidden within the first and second hinge bosses, which both protects the flexible connector conductor and optimizes its appearance. During hinge rotation, the relative distance between the first and second connecting seats changes. Since the flexible connector conductor is basically fixed relative to the first and second sealing plugs, the portion of the flexible connector conductor located within the third and fourth through holes will bend or stretch during rotation. This design sets the diameter of the third and fourth through holes to be larger than the outer diameter of the flexible connector conductor, providing sufficient space for deformation of the flexible connector conductor during rotation, ensuring smooth hinge rotation, and avoiding damage to the flexible connector conductor.

[0021] In one embodiment, a first shielding plate is connected between the two first hinge bosses, avoiding the second hinge boss. Within the rotation range set by the first hinge support and the second hinge support, the first shielding plate always blocks the opening at the end of the fourth through hole.

[0022] In this embodiment, the dynamic following shielding function of the first shielding plate enables continuous protection of the fourth perforation opening within its full rotation range. This effectively blocks dust and foreign objects from entering the wiring channel, preventing conductor damage due to foreign object scratches or channel blockage that could affect signal transmission. Simultaneously, it significantly reduces the total amount of liquid entering the channel, lowers the waterproofing pressure on the sealing plug, and extends the service life of the sealing plug. On the other hand, the first shielding plate has a simple structure, requiring only the addition of a sheet-like component between the two first hinge bosses. It does not require changes to the existing perforation layout, hinge structure, or sealing design, resulting in low processing and assembly costs. Furthermore, its lightweight design meets the volume control requirements of smart glasses.

[0023] On the other hand, embodiments of this application also provide smart glasses, including: Temples; Picture frames; As described above, in a waterproof hinge, the first hinge support is connected to the temple, and the second hinge support is connected to the frame. The flexible conductor has one end connected to the first component inside the temple, and the other end extends out of the temple through the first wire hole of the first sealing plug, and extends into the frame through the second wire hole of the second sealing plug to connect to the second component inside the frame. The flexible conductor is tightly fitted to the first sealing plug and the second sealing plug to form a waterproof structure.

[0024] In this embodiment of the smart glasses solution, the waterproof hinge's wiring channel and sealing structure ensure stable circuit connectivity of the flexible conductors, preventing short circuits and poor contact caused by liquids or foreign objects. This allows core smart functions such as photography, data processing, and audio output to operate normally in various usage scenarios (such as sports wear and outdoor use), improving product reliability. High waterproof performance effectively protects internal electronic components and flexible conductors, reducing damage caused by water corrosion and foreign object abrasion, lowering the product failure rate, extending the overall lifespan of the smart glasses, and reducing user maintenance costs and replacement frequency.

[0025] In one embodiment, the temple is provided with a first mounting opening corresponding to the shape of the first connecting seat, and the first connecting seat is at least partially embedded in the first mounting opening; And / or, the frame is provided with a second mounting port corresponding to the shape of the second connector, and the second connector is at least partially embedded in the second mounting port.

[0026] In this embodiment, the embedded installation of the first and / or second connecting seats transforms the surface contact between the waterproof hinge and the temple / frame into a deep fit, significantly increasing the contact area. When the smart glasses are unfolded for wearing or folded for storage, the external forces (such as bending or squeezing) at the connection between the temple / frame and the waterproof hinge can be evenly distributed to the internal structure of the temple through the fitting surface. This avoids the loosening, deformation, or even cracking of the connecting seat caused by concentrated force in traditional surface connections, thus improving the overall structural strength. The tight fit between the first / second connecting seat and the first / second mounting port provides a stable foundation for additional sealing treatment. Waterproof adhesive strips or sealant can be applied to the gap between the connecting seat and the mounting port to form a double protection of tight fit + adhesive strip sealing. This, together with the sealing plug of the waterproof hinge itself and the first baffle, forms a protective closed loop, further blocking the path of liquid seeping from the connection point into the temple or frame cavity.

[0027] In one embodiment, the temple includes a temple base and a temple cover, the first component is installed in the temple base; the first connector is embedded in the temple base and locked to the temple base by a first screw, and the temple cover is placed on the temple base and covers the first screw.

[0028] In this embodiment, the first connecting seat employs a dual fixing method of embedded mounting and screw locking, effectively limiting multi-directional displacement of the first connecting seat. Even under harsh conditions such as frequent folding and external impacts, it can maintain a stable connection between the connecting seat and the temple, preventing misalignment of the threading channel and sealing failure due to loose connection, thus ensuring the stable performance of the waterproof hinge. The temple cover plate conceals the first screw and internal structure, making the temple appearance flat and without protrusions, enhancing the product's design aesthetics. At the same time, the sealing fit between the cover plate and the bottom shell reduces the infiltration path of external foreign objects and liquids, further strengthening the protective performance of the temple, and working together with the waterproof hinge to build a more comprehensive protection system.

[0029] In one embodiment, the first connecting seat includes a snap-fit ​​portion and a threaded locking portion disposed opposite to each other at both ends of the first connecting seat. The snap-fit ​​portion snaps onto the end of the temple base near the frame. The threaded locking portion is configured to cooperate with the first screw. The temple cover plate covers the threaded locking portion.

[0030] In this embodiment, the quick positioning of the snap-fit ​​part reduces the alignment and adjustment time required for traditional pure screw fixing. Operators can complete the initial fixing without supporting the connector with both hands, and subsequent assembly can be completed with just a single first screw. Compared to multi-screw fixing or pure snap-fit ​​fixing, the assembly steps are fewer, making it suitable for mass production on assembly lines. At the same time, the dual fixing of snap-fit ​​and screw is complementary. The snap-fit ​​part can buffer instantaneous impact forces (such as vibrations from accidental drops), preventing the screw from stripping due to excessive instantaneous force; the screw locking compensates for the loosening problem caused by elastic fatigue of the snap-fit ​​after long-term use. The combination of the two ensures that the connector remains stable under scenarios such as frequent folding and external impact, effectively preventing misalignment of the threading channel and failure of the sealing plug due to loose connection.

[0031] In one embodiment, the frame includes a first frame shell and a second frame shell that are adapted to each other. The second connecting seat is embedded in the first frame shell and locked to the first frame shell by a second screw. The second frame shell covers the first frame shell and covers the second screw.

[0032] In this embodiment, during assembly, the first frame shell serves as the basic assembly carrier, independently enabling the installation of the second component and the embedded fixing of the second connector. Operators are not affected by the obstruction of the second frame shell and can accurately position components and tighten the second screw in an open space, significantly reducing assembly difficulty. If subsequent repairs are needed (such as replacing the camera module or inspecting the conductor), only the second frame shell needs to be removed to expose the internal structure, eliminating the need to disassemble the waterproof hinge or the entire frame. This avoids the destructive disassembly required for traditional one-piece frames, shortening repair time and reducing repair costs. After the second frame shell is closed, it completely covers the second screw and the internal structure, eliminating any cosmetic defects caused by exposed screw heads, keeping the outer surface of the frame smooth and flat, and optimizing the product design.

[0036] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] With the rapid development of smart wearable technology, smart glasses such as AI glasses and VR glasses are becoming increasingly popular. Their functional integration is constantly improving, and they typically need to simultaneously possess core functions such as image acquisition (taking photos / videos), data storage and processing, and audio output (sound output). To achieve these functions, smart glasses need to integrate various electronic components such as camera modules, processors, memory, speakers, and batteries within the frame, temples, and other structures. The signal transmission and circuit connection between the frame and temples are generally achieved using flexible printed circuit boards (FPCs) connected through the glasses' hinges.

[0040] Specifically, to allow the FPC to pass through the hinge structure and complete the circuit connection between the frame and temples, holes or gaps adapted for FPC wiring need to be made in the hinge body and corresponding assembly positions. However, in actual use scenarios, smart glasses need to be worn on the user's head for extended periods, inevitably coming into contact with liquids or moisture such as sweat, rain, and ambient humidity. Since the holes / gaps at the hinge are designed to accommodate FPC installation, their sealing performance is limited by the structure and cannot be completely closed. This allows sweat to easily seep from the user's scalp to the hinge surface, and rainwater or other liquids in the environment may also directly splash onto the hinge area. These liquids can easily seep into the frame and temples through the assembly gaps between the holes and the FPC. The electronic components inside the frame and temples are sensitive to moisture. Once liquid seeps in, it can not only cause short circuits and corrosion, but also lead to abnormal signal transmission and functional failure. In severe cases, it can directly cause permanent damage to electronic components, significantly reducing the lifespan and reliability of the smart glasses.

[0041] To overcome the above technical problems, this application provides a waterproof hinge for smart glasses. In application, the frame 7 and temple 6 of the smart glasses are rotatably connected by the hinge, so as to realize the functions of unfolding and wearing the smart glasses and folding and storing them.

[0042] Reference Figures 1-5 The waterproof hinge provided in this embodiment includes a first hinge support 1, a second hinge support 2, a first sealing plug 3, and a second sealing plug 4. The first hinge support 1 includes a first connecting seat 11 and a first hinge portion 12 connected together. The first connecting seat 11 is used to connect the temple 6 and has a first through hole 111 for connecting the inner and outer areas of the temple 6. The second hinge support 2 includes a second connecting seat 21 and a second hinge portion 22 connected together. The second connecting seat 21 is used to connect the frame 7 and has a second through hole 211 for connecting the inner and outer areas of the frame 7. The second hinge portion 22 is hinged to the first hinge portion 12. The first sealing plug 3 is configured to cooperate with the first through hole 111 and has a first wire hole 31 that allows the flexible conductor 5 to pass through. The first sealing plug 3 is installed in the first through hole 111. The second sealing plug 4 is configured to cooperate with the second through hole 211 and has a second wire hole 41 that allows the flexible conductor 5 to pass through. The second sealing plug 4 is installed in the second through hole 211.

[0043] In the specific structure, during application, the temple 6 includes a temple housing. The temple housing has a first cavity to provide mounting support and protection for the first component 63 inside. In this embodiment, regarding the temple 6, the space inside the first cavity is called the interior, and the space outside the temple 6 is called the exterior. Therefore, the first through hole 111 connecting the interior and exterior of the temple 6 is a through hole structure connecting the first cavity and the external environment. The end of the temple 6 near the frame 7 is connected to the first hinge support 1. In order to allow the flexible conductor 5 to pass out from the inside of the first cavity, a first mounting port corresponding to the mounting of the first hinge support 1 is usually provided on the outer shell of the temple 6. This allows the first hinge support 1 to be installed in the first mounting port, which can be completely sealed with the first sealing plug 3. At the same time, the flexible conductor 5 can extend to the outside of the temple 6 through the first mounting port and the first wire hole 31 of the first sealing plug 3.

[0044] The eyeglass frame 7 includes an eyeglass frame housing. The eyeglass frame housing has a second cavity to provide mounting support and protection for the second component 73 inside. In this embodiment, regarding the eyeglass frame 7, the space inside the second cavity is called the interior, and the space outside the eyeglass frame 7 is called the exterior. Therefore, the second through hole 211 connecting the interior and exterior of the eyeglass frame 7 is a through hole structure connecting the second cavity and the external environment. The end of the eyeglass frame 7 near the temple 6 is connected to the second hinge support 2. In order to allow the flexible conductor 5 to pass out from the interior of the second cavity, a second mounting port corresponding to the mounting of the second hinge support 2 is usually provided on the outer shell of the eyeglass frame 7. This allows the second hinge support 2 to be installed in the second mounting port, which can be completely sealed with the second sealing plug 4. At the same time, the flexible conductor 5 can extend to the exterior of the eyeglass frame 7 through the second mounting port and the second wire hole 41 of the second sealing plug 4.

[0045] The flexible conductor 5 is used to connect the temple 6 and the first component 63 and the second component 73 inside the frame 7, enabling the transmission of current and electrical signals between the first component 63 and the second component 73. The flexible conductor 5 can be a flexible circuit board, wire, etc., which can bend and stretch with the rotation of the temple 6.

[0046] The first hinge part 12 and the second hinge part 22 are hinged together, which can be achieved by connecting structures such as pins and pivots. During the rotation of the temple 6, the first hinge part 12 and the second hinge part 22 rotate relative to the pins and pivots.

[0047] The first sealing plug 3 is a customized fit structure, with its shape precisely matching the inner wall contour of the first through hole 111, ensuring no obvious gap between it and the inner wall of the first through hole 111 after installation. The size of its first wire-passing hole 31 is adapted to the outer diameter of the flexible connector conductor 5, allowing the flexible connector conductor 5 to pass through smoothly while minimizing the fit gap between the flexible connector conductor 5 and the first wire-passing hole 31. After installation, the flexible connector conductor 5 and the wall of the first wire-passing hole 31 are in close contact, forming a gapless seal. The second sealing plug 4 has a shape precisely matching the inner wall contour of the second through hole 211, ensuring no obvious gap between it and the inner wall of the second through hole 211 after installation. The size of its second wire-passing hole 41 is adapted to the outer diameter of the flexible connector conductor 5, allowing the conductor to pass through smoothly while minimizing the fit gap between the flexible connector conductor 5 and the second wire-passing hole 41. After installation, the flexible connector conductor 5 and the wall of the second wire-passing hole 41 are in close contact, forming a gapless seal.

[0048] The first sealing plug 3 and the second sealing plug 4 are made of elastic materials, such as silicone or rubber.

[0049] The waterproof hinge in this embodiment achieves a harmonious balance between structural sealing and functional practicality through a synergistic design of double hinge supports and double sealing plugs. Its core advantages are significant: Firstly, the precise and tight fit of the two sealing plugs with the corresponding perforation inner walls and the surface of the flexible conductor 5 forms a double sealing barrier, effectively preventing sweat, rainwater, and ambient moisture from seeping into the frame 7 or temple 6 through the perforation gaps at the hinge. This avoids short circuits, corrosion, malfunctions, or permanent damage to internal electronic components due to water exposure, significantly improving the waterproof performance, reliability, and lifespan of the smart glasses. On the one hand, the overall structure is simple and compact, without complex additional parts, which makes it easy to process and assemble and highly adaptable. The wire hole of the sealing plug can be flexibly adjusted according to the size of the flexible connector conductor 5. The hinge support structure can be adapted to different specifications of frame 7 and temple 6, and can be widely used in various smart glasses products such as AI glasses and VR glasses. At the same time, the sealing structure and the hinge rotation function do not interfere with each other, which not only ensures the stability of the circuit connection, but also does not affect the smooth operation of unfolding, wearing and folding the smart glasses. It can also avoid wear on the flexible connector conductor 5 during assembly, reduce user maintenance costs, and significantly enhance the market competitiveness of the product.

[0050] In one embodiment, the diameter of the first through hole 111 is constricted as it extends from the inside to the outside along the through direction of the first through hole 111. The deeper the first sealing plug 3 is inserted into the first through hole 111, the smaller the diameter of the first wire hole 31 is squeezed and constricted. And / or, extending from the inside to the outside along the through direction of the second perforation 211, the diameter of the second perforation 211 is constricted, and the deeper the second sealing plug 4 is inserted into the second perforation 211, the smaller the diameter of the second wire hole 41 is squeezed and constricted.

[0051] The first perforation 111 is a perforation connecting the first inner cavity of the temple 6 to the external environment, and the extension from the inside to the outside refers to the direction of extension from the first inner cavity to the external environment. Similarly, the second perforation 211 is a perforation connecting the second inner cavity of the frame 7 to the external environment, and the extension from the inside to the outside refers to the direction of extension from the second inner cavity to the external environment.

[0052] The first perforation 111 serves as a communication channel between the first inner cavity of the temple 6 and the external environment. Along the penetrating direction from the first inner cavity to the external environment, its diameter exhibits a continuous or stepped contraction state. That is, the diameter of the first perforation 111 is largest at the starting end on the inner cavity side of the temple 6, and gradually decreases as it extends outward from the hinge, forming a conical (or stepped conical) through-hole structure that is wider inside and narrower outside. The shape of the first sealing plug 3 is designed synchronously with the contraction shape of the first perforation 111, and the whole is a conical (or stepped conical) shape that complements the first perforation 111. During installation, it is inserted from the large diameter end (inner cavity side) of the first perforation 111 to the small diameter end (outer side). The self-positioning and locking of the sealing plug are achieved by using the contraction slope of the first perforation 111, so as to avoid axial displacement of the first sealing plug 3 during use.

[0053] Similarly, the second perforation 211 serves as a communication channel between the second inner cavity of the frame 7 and the external environment. Along the penetrating direction from the second inner cavity to the external environment, it also adopts a shrinking aperture design with a wider inner diameter and a narrower outer diameter. The shape of the second sealing plug 4 is designed synchronously with the shrinking shape of the second perforation 211, and the whole is a cone (or stepped cone) that complements the second perforation 211. During installation, it is inserted from the large diameter end (inner cavity side) of the second perforation 211 to the small diameter end (outer side). The shrinking slope of the second perforation 211 is used to achieve the self-positioning and clamping of the sealing plug, so as to avoid axial displacement of the second sealing plug 4 during use.

[0054] In this embodiment, the conical inner cavity formed by the shrinking first perforation 111 and / or the second perforation 211 provides a wedge-shaped positioning space for the sealing plug. After the elastic first sealing plug 3 and / or the second sealing plug 4 are inserted, as the insertion depth of the first sealing plug 3 and the second sealing plug 4 increases, the shrinking slope of the perforation will generate radial extrusion force on the sealing plug, causing the outer wall of the sealing plug to fit tightly against the inner wall of the perforation. At the same time, the inner wall of the wire hole of the sealing plug will also generate radial extrusion force against the flexible conductor 5, further reducing the gap between the sealing plug and the conductor, achieving a passive extrusion sealing effect. Compared with a perforation of equal diameter, this structure can significantly improve the tightness of the sealing interface. In addition, the shrinking structure with a wider inner diameter and a narrower outer diameter forms a limiting step in the aperture direction. After the sealing plug is inserted from the inner cavity side, its maximum outer diameter part will be blocked by the shrinking slope of the perforation, preventing it from falling out to the external environment. At the same time, when the glasses rotate, vibrate, or are pulled by external forces, this limiting structure can effectively restrict the axial displacement of the sealing plug, avoiding sealing failure caused by displacement.

[0055] In one embodiment, the first sealing plug 3 includes a first insert portion 33 that is inserted into the first perforation 111 and extends from the inside to the outside along the through direction of the first perforation 111. The outer diameter of the first insert portion 33 is constricted. The deeper the first insert portion 33 is inserted into the first perforation 111, the smaller the diameter of the first wire hole 31 is squeezed and constricted. And / or, the second sealing plug 4 includes a second insertion portion 43 that is inserted into the second perforation 211 and extends from the inside to the outside along the through direction of the second perforation 211. The outer diameter of the second insertion portion 43 is constricted. As the second insertion portion 43 is inserted deeper into the first perforation 211, the diameter of the second wire hole 41 is squeezed and constricted to a smaller size.

[0056] In this embodiment, a tapered, cone-shaped first insert 33 and / or second insert 43 are used to form a wedge-shaped inlay structure with the first through hole 111 and / or the second through hole 211. After the first insert 33 and / or the second sealing plug 4 are inserted, the tapering slope of the through hole generates a radial compressive force across the entire area of ​​the insert along the extension direction of the through hole. This causes the inner wall of the through hole of the insert to exert a radial compressive force on the flexible connector conductor 5, further reducing the gap between the sealing plug and the conductor, extending the sealing path, and enhancing the sealing effect. In addition, the cone-shaped insert also has the advantage of convenient and quick insertion and installation.

[0057] In one embodiment, reference is made to Figure 4 The first sealing plug 3 includes a first insertion part 33 and a first limiting part 32 connected together. The first insertion part 33 is inserted into the first through hole 111, and the first limiting part 32 abuts against the inner end face of the first connecting seat 11 to form an annular sealing structure. And / or, the second sealing plug 4 includes a connected second insertion portion 43 and a second limiting portion 42, the second insertion portion 43 being inserted into the second through hole 211, and the second limiting portion 42 abutting against the inner end face of the second connecting seat 21 to form an annular sealing structure.

[0058] The first sealing plug 3 consists of an integrally formed first insertion part 33 and a first limiting part 32. The shape of the first insertion part 33 is perfectly matched with the inner wall contour of the first perforation 111, ensuring a tight fit with the hole wall after insertion. The first limiting part 32 is an annular or sheet-like structure with an outer diameter larger than the diameter of the first perforation 111. When the first insertion part 33 is fully inserted into the first perforation 111, the first limiting part 32 will tightly abut against the inner end face of the first connecting seat 11 (i.e., the end face facing the first inner cavity of the temple 6), forming an axial limit. Similarly, the second insertion part 43 of the second sealing plug 4 is correspondingly inserted into the second perforation 211 of the second connecting seat 21. The outer diameter of the second limiting part 42 is larger than the diameter of the second perforation 211. After assembly, it abuts against the inner end face of the second connecting seat 21 (the end face facing the second inner cavity of the frame 7), achieving the same axial positioning effect as the first sealing plug 3.

[0059] In this embodiment, the connection between the limiting part and the insertion part forms a natural stepped surface. During assembly, the inner end face of the connector is used as the positioning reference. The abutting action of the limiting part ensures that the insertion part is embedded in the perforation at a consistent depth, avoiding problems such as insufficient sealing due to shallow insertion or compression of the flexible conductor 5 due to excessive insertion. At the same time, the tight fit between the stepped surface and the end face of the connector can further block the path of liquid penetration from the end face gap. Combined with the three-dimensional sealing system formed by the end face sealing, the waterproof protection level is greatly improved, further reducing the risk of damage to electronic components caused by liquid infiltration.

[0060] In one embodiment, reference is made to Figure 2 and Figure 6 The penetrating direction of the first wire hole 31 extends along an arc, and the perpendicular bisectors of the two ends of the first wire hole 31 form an angle with each other.

[0061] In application, the first hinge support 1 is usually connected to the inner corner of the temple 6 and the frame 7. That is, the first hinge support 1 is located on the side of the temple 6 rather than the end face. The first wire hole 31 is set to pass through along an arc, and the perpendicular lines of the two ports form an angle with each other. That is, the first wire hole 31 passes through the first sealing plug 3 along an arc. Its overall trajectory is a smooth arc (not a straight line). The perpendicular lines of the two ports (inner port and outer port) of the first wire hole 31 have a clear angle. The inner port is the port that connects to the first inner cavity of the temple 6, where the perpendicular line extends along the length direction of the temple 6. The outer port is the port facing the internal space of the hinge, where the perpendicular line tends to extend perpendicular to the length direction of the temple 6. This makes the arc trajectory accurately connect the wiring requirements of the length direction of the temple 6 and the perpendicular length direction of the temple 6. The arc design is perfectly matched with the side assembly position of the first hinge support 1. Since the first hinge support 1 is connected to the side of the temple 6, after the flexible conductor 5 is led out from the inside of the temple 6 (arranged along the length direction), it needs to turn to the inside of the hinge (towards the perpendicular length direction of the temple 6) to connect to the side circuit of the frame 7. The trajectory of the arc-shaped wire hole matches this turning path, avoiding excessive bending and damage to the flexible conductor 5.

[0062] In this embodiment, the conductor's smooth turning is achieved through the arc trajectory of the first wire-passing hole 31, which solves the stress concentration and breakage risk caused by the forced bending of the conductor in a straight wire-passing hole, extends the service life of the flexible connector conductor 5, and precisely guides the direction of the flexible connector conductor 5 to avoid misalignment or breakage of the flexible connector conductor 5 inside the hinge, ensuring the stability of circuit signal transmission. On the other hand, the arc design is highly compatible with the mounting position on the side of the hinge support, which can make full use of the narrow space to arrange the wiring channel, avoid increasing the hinge volume, meet the lightweight requirements of smart glasses, and the matching design of the arc-shaped sealing plug and the arc-shaped wire-passing hole ensures that the turning structure does not affect the sealing performance.

[0063] In one embodiment, reference is made to Figure 1 and Figure 4 The first hinge portion 12 and the second hinge portion 22 are configured such that one includes two spaced-apart first hinge bosses 121 and the other includes a second hinge boss 221. The two first hinge bosses 121 are respectively hinged to two opposite sides of the second hinge boss 221. The first hinge bosses 121 and the second hinge boss 221 are interference-fitted to form a damping structure.

[0064] If the first hinge part 12 adopts a double-protrusion design, it includes two parallel and spaced-apart first hinge protrusions 121, with a gap between the two protrusions to accommodate the insertion of a single protrusion. Correspondingly, the second hinge part 22 is provided with a second hinge protrusion 221, the thickness of which matches the spacing width between the two first hinge protrusions 121. During assembly, the second hinge protrusion 221 is inserted into the gap between the two first hinge protrusions 121, and the hinge shaft (such as a pin) passes through the first hinge protrusion 121 and the second hinge protrusion 221 in sequence to achieve a rotational connection between the two. Conversely, if the second hinge part 22 is a double-protrusion structure and the first hinge part 12 is a single-protrusion structure, their layout logic is the same, only the protrusion positions are interchanged, ultimately forming a symmetrical nested structure of double protrusions enclosing a single protrusion.

[0065] To achieve the hinge, each hinge boss has a coaxial hinge hole to ensure that there is no radial offset after the hinge shaft passes through; the end faces of the first hinge boss 121 and the second hinge boss 221 are both smoothed to avoid jamming or wear during rotation; at the same time, the height and width of the boss are designed to match the overall size of the hinge, which not only ensures sufficient structural strength to withstand the external force when folding, but also avoids the hinge from being too bulky due to the size of the boss, thus meeting the lightweight requirements of smart glasses.

[0066] In this embodiment, the structure of a single boss encased by two bosses significantly improves the deformation resistance and rotational stability of the hinge, avoiding damage caused by concentrated stress in traditional hinge structures, extending the hinge's lifespan, and ensuring smooth and precise operation when the smart glasses are unfolded and folded, thus enhancing the user experience. On the other hand, the nesting gap provides dedicated routing space for the flexible conductor 5, reducing the risk of wear and ensuring the stability of circuit signal transmission. Furthermore, this structural design eliminates the need for additional protective components; the optimization of the boss layout alone achieves a dual improvement in stability and protection, simplifying the overall hinge structure and reducing manufacturing costs. In addition, the interference fit between the first hinge boss 121 and the second hinge boss 221 forms a damping structure, preventing relative free rotation between the first hinge part 12 and the second hinge part 22, maintaining the stability of the smart glasses' temples in unfolded or folded states.

[0067] In one embodiment, a third through hole 1211 is formed between the two first hinge bosses 121, and a fourth through hole 2211 is provided on the second hinge boss 221. The first through hole 111, the third through hole 1211, the fourth through hole 2211 and the second through hole 211 pass through to form a connected wire channel. The two first hinge parts 12 and the two second hinge parts 22 are respectively hinged by independent screws. The two screws are spaced apart in the fourth through hole 2211 to form a vertical space.

[0068] The wiring channel is formed by the sequential connection of the first through hole 111, the third through hole 1211, the fourth through hole 2211, and the second through hole 211. The third through hole 1211 is located between the two first hinge bosses 121, and its axis is aligned with the axis of the outer port of the first through hole 111, ensuring that the conductor can smoothly enter after passing through the first through hole 111. The fourth through hole 2211 is located at the center of the second hinge boss 221, and its axis is coaxial with the axis of the third through hole 1211, so that the conductor can smoothly transition from the fourth through hole 2211 to the second through hole 211, ultimately forming a continuous wiring path of "inner cavity of temple 6 → first through hole 111 → third through hole 1211 → fourth through hole 2211 → second through hole 211 → inner cavity of frame 7".

[0069] The two second hinge parts 22 on both sides are respectively hinged to the two sides of the first hinge part 12 by independent screws, keeping the fourth through hole 2211 in the middle clear and avoiding contact interference with the flexible connecting conductor 5 inside the fourth through hole 2211. At the same time, the structure with hinges on both sides has the advantages of good stability and high durability.

[0070] In this embodiment, the wiring channel completely encloses the flexible conductor 5 from the inner cavity of the temple 6 to the inner cavity of the frame 7 within the internal structure of the hinge, preventing the conductor from being exposed to the hinge gap or the external environment. Specifically, the flexible conductor 5 is guided and turned by the arc structure in the first wire hole 31, and is positioned by the second hinge boss 221 when it enters the third through hole 1211 and passes through the fourth through hole 2211. Finally, it enters the inner cavity of the frame 7 through the second wire hole 41, and runs along the fixed channel throughout. Even when the hinge rotates, the flexible conductor 5 only moves slightly within the channel and will not deviate, become entangled, or rub against external components. Because the third through hole 1211 and the fourth through hole 2211 rotate synchronously with the hinge (the first hinge boss 121 rotates, driving the third through hole 1211, and the second hinge boss 221 rotates, driving the fourth through hole 2211), and the two always remain coaxial, the wire channel will not be misaligned or deformed during rotation. The conductor only makes adaptive bending and fine adjustment with the rotation of the channel, avoiding the conductor being pulled or squeezed due to channel offset, thus ensuring the continuity and stability of circuit signal transmission.

[0071] In one embodiment, the aperture size of the third through hole 1211 and the fourth through hole 2211 is larger than the outer diameter of the flexible conductor 5, so that the flexible conductor 5 can be adaptively bent or stretched in the third through hole 1211 and the fourth through hole 2211 during the relative rotation of the first hinge support 1 and the second hinge support 2. The opening angle of the fourth through hole 2211 near the third through hole 1211 relative to the hinge axis is 10 to 90 degrees.

[0072] The purpose of the third through hole 1211 and the fourth through hole 2211 is to provide a path for the flexible connector conductor 5 to pass through. After passing through, the flexible connector conductor 5 can be hidden inside the first hinge boss 121 and the second hinge boss 221, which not only protects the flexible connector conductor 5 but also optimizes its appearance. During the hinge rotation, the relative distance between the first connecting seat 11 and the second connecting seat 21 will change. Since the flexible connector conductor 5 is basically fixed relative to the first sealing plug 3 and the second sealing plug 4, the part of the flexible connector conductor 5 located in the third through hole 1211 and the fourth through hole 2211 will bend or stretch during the rotation. In this solution, the diameter of the third through hole 1211 and the fourth through hole 2211 is set to be larger than the outer diameter of the flexible connector conductor 5, providing sufficient space for the deformation of the flexible connector conductor 5 during rotation, ensuring the smoothness of the hinge rotation process, and avoiding damage to the flexible connector conductor 5.

[0073] Furthermore, the opening of the fourth through hole 2211 near the third through hole 1211 is the outer port of the fourth through hole 2211. Taking the rotation axis of the waterproof hinge as a reference, the two sides of the outer port of the fourth through hole 2211 parallel to the axis are respectively the first side and the second side. The line connecting the first side and the rotation axis is the first side line, and the line connecting the second side and the rotation axis is the second side line. The angle between the first side line and the second side line is the opening angle of the outer port of the fourth through hole 2211. This opening angle is set to 10~90 degrees, which can meet the movement requirements of the flexible conductor 5 and avoid the internal flexible conductor 5 being exposed due to an excessively large opening.

[0074] Preferably, along the thickness direction of the flexible conductor 5, the aperture size of the third through hole 1211 and the fourth through hole 2211 is not less than three times the thickness size of the flexible conductor 5, so as to provide sufficient spare space for the movement of the flexible conductor 5.

[0075] In one embodiment, reference is made to Figure 2 and Figure 4 A first shielding plate 122 and a second shielding plate 114 are connected between the two first hinge protrusions 121, which are arranged to avoid the second hinge protrusion 221. During the rotation of the first hinge support 1 and the second hinge support 2, the first shielding plate 122 and the second shielding plate 114 respectively shield the opening at the end of the fourth through hole 2211.

[0076] The first baffle plate 122 is connected between the two first hinge bosses 121 and has a sheet-like structure. Similarly, the second baffle plate 114 is connected between the two first hinge bosses 121 and has a sheet-like structure. It is specifically formed in the first connecting seat 11 and is set at an angle to the first baffle plate 122. The installation positions of the first shielding plate 122 and the second shielding plate 114 avoid the rotation trajectory of the second hinge boss 221, so as not to interfere with the second hinge boss 221, and to cover the end opening of the fourth through hole 2211 (i.e. the side port of the fourth through hole 2211 facing the external environment). The size and shape of the first shielding plate 122 and the second shielding plate 114 are customized according to the position of the fourth through hole 2211 and the rotation range of the first and second hinge supports 2, so as to ensure that the first shielding plate 122 and the second shielding plate 114 always maintain a corresponding shielding relationship with the end opening of the fourth through hole 2211 within the full rotation range of the smart glasses unfolded (wearing state) and folded (storage state), without any exposed gaps. The edges of the first baffle plate 122 and the second baffle plate 114 are rounded to prevent them from scratching the surface of the second hinge boss 221 when rotating. At the same time, a small buffer space is reserved between the first baffle plate 122 and the second baffle plate 114 and the second hinge boss 221 to ensure smooth rotation and reduce the path of dust and liquid entering the fourth perforation 2211 by close-range shielding.

[0077] In this embodiment, the dynamic following shielding function of the first shielding plate 122 and the second shielding plate 114 achieves continuous protection of the fourth perforation 2211 opening within the full rotation range, effectively blocking dust and foreign objects from entering the wiring channel, preventing conductor damage due to foreign object scratches or channel blockage from affecting signal transmission, while significantly reducing the total amount of liquid entering the channel, reducing the waterproof pressure on the sealing plug, and extending the service life of the sealing plug; on the other hand, the first shielding plate 122 and the second shielding plate 114 have a simple structure, requiring only the addition of a sheet-like component between the two first hinge bosses 121, without changing the existing perforation layout, hinge structure, or sealing design, resulting in low processing and assembly costs, and the lightweight design meets the volume control requirements of smart glasses.

[0078] On the other hand, refer to Figures 6-8 This application also provides a smart glasses embodiment, including: Temple length 6; Frame 7; As described above, in a waterproof hinge, the first hinge support 1 is connected to the temple 6, and the second hinge support 2 is connected to the frame 7. The flexible conductor 5 has one end connected to the first component 63 inside the temple 6, and the other end extends out of the temple 6 through the first wire hole 31 of the first sealing plug 3, and extends into the frame 7 through the second wire hole 41 of the second sealing plug 4 to connect to the second component 73 inside the frame 7. The flexible conductor 5 is tightly fitted with the first sealing plug 3 and the second sealing plug 4 to form a waterproof structure.

[0079] The temple 6 and frame 7 serve as the main support structure of the smart glasses. They are rotatably connected by the aforementioned waterproof hinge. The first hinge support 1 of the waterproof hinge is fixedly connected to the side of the temple 6 (e.g., by screw fastening, snap-fit, or integral molding) to ensure the connection strength to withstand external forces during wearing and folding. The second hinge support 2 is fixedly connected to the corresponding side of the frame 7. After assembly, the rotation axis of the hinge coincides with the folding axis of the smart glasses, ensuring the accuracy of unfolding for wearing and folding for storage. The flexible conductor 5 (such as FPC or flexible cable) serves as the core of the circuit connection. One end of it is welded to the first component 63 (such as processor, battery, or speaker) inside the temple 6 or fixed through a connector to ensure stable signal and power transmission. The other end extends along the inner cavity of the temple 6 to the first through hole 111 of the first connecting seat 11, passes through the first wire hole 31 of the first sealing plug 3, and enters the through wire channel of the waterproof hinge (passing through the third through hole 1211 and the fourth through hole 2211 in sequence). Then it passes through the second wire hole 41 of the second sealing plug 4 and enters the inner cavity of the frame 7. Finally, it connects with the second component 73 (such as camera module, display drive circuit, or sensor) inside the frame 7 to form a complete circuit path.

[0080] In this embodiment of the smart glasses solution, the wiring channel and sealing structure of the waterproof hinge ensure stable circuit connectivity of the flexible conductor 5, preventing short circuits and poor contact caused by liquids or foreign objects. This allows core smart functions such as photography, data processing, and audio output to operate normally in various usage scenarios (such as sports wear and outdoor use), improving product reliability. High waterproof performance effectively protects internal electronic components and the flexible conductor 5, reducing component damage caused by water corrosion and foreign object wear, lowering the product failure rate, extending the overall lifespan of the smart glasses, and reducing user maintenance costs and replacement frequency.

[0081] In one embodiment, the temple 6 is provided with a first mounting port corresponding to the shape of the first connecting seat 11, and the first connecting seat 11 is at least partially embedded in the first mounting port; And / or, the frame 7 is provided with a second mounting port corresponding to the shape of the second connecting seat 21, and the second connecting seat 21 is at least partially embedded in the second mounting port.

[0082] The first mounting opening of the temple 6 is precisely machined according to the shape of the first connecting seat 11 (such as rectangular, trapezoidal, or custom irregular structure). Its inner cavity size and depth are perfectly matched with the outer contour of the first connecting seat 11, ensuring that at least part (usually 1 / 2-2 / 3 of the volume) of the first connecting seat 11 is embedded in the first mounting opening. After embedding, the outer wall of the first connecting seat 11 and the inner wall of the first mounting opening fit tightly without obvious assembly gaps. Similarly, the second mounting opening of the frame 7 is adapted to the shape of the second connecting seat 21, and the second connecting seat 21 is at least partially embedded in the second mounting opening, forming a tight connection structure. After embedded installation, the connection strength can be further strengthened by auxiliary fixing structures. For example, buckles and slots can be set on the mating surfaces of the first connecting seat 11 and the first mounting opening to achieve mechanical locking during embedding; or structural adhesive can be filled into the fitting gap to enhance sealing and connection stability; or screws can be used to penetrate the pre-drilled screw holes in the side wall of the temple 6 and the first connecting seat 11 to achieve detachable fixing. At the same time, the screw head is embedded in the inner wall of the temple 6 and does not protrude from the surface to affect wearing comfort. The second connecting seat 21 can be fixed in the same way.

[0083] In this embodiment, the embedded installation of the first connecting seat 11 and / or the second connecting seat 21 changes the connection surface between the waterproof hinge and the temple 6 / frame 7 from surface contact to deep engagement, significantly increasing the contact area. When the smart glasses are unfolded for wearing or folded for storage, the external force (such as bending or squeezing) borne by the connection between the temple 6 / frame 7 and the waterproof hinge can be evenly distributed to the internal structure of the temple 6 through the engagement surface. This avoids the loosening, deformation, or even cracking of the temple 6 caused by the concentrated force of traditional surface connections, thus improving the overall structural strength. The tight engagement of the first connecting seat 11 / second connecting seat 21 with the first mounting port / second mounting port provides a stable foundation for additional sealing treatment. Waterproof adhesive strips or sealant can be applied to the engagement gap between the connecting seat and the mounting port to form a double protection of tight engagement + adhesive strip sealing. This, together with the sealing plug of the waterproof hinge itself, the first shielding plate 122, and the second shielding plate 114, forms a protective closed loop, further blocking the path of liquid seeping from the connection part into the inner cavity of the temple 6 or frame 7.

[0084] In one embodiment, reference is made to Figure 9 and Figure 10 The temple 6 includes a temple base 61 and a temple cover 62. The first component 63 is installed inside the temple base 61. The first connecting seat 11 is embedded in the temple base 61 and locked to the temple base 61 by the first screw 64. The temple cover 62 covers the temple base 61 and covers the first screw 64.

[0085] During assembly, the first connecting seat 11 is first embedded in the first mounting opening of the temple base 61, and its outer wall is tightly fitted with the inner wall of the first mounting opening to achieve initial positioning; then, the first screw 64 passes through the corresponding hole reserved in the first connecting seat 11 and the temple base 61 to lock the first connecting seat 11 and the temple base 61 into one piece. The locking depth of the first screw 64 is controlled so that the screw head is completely embedded in the countersunk hole of the temple base 61 or the first connecting seat 11, and does not protrude from the surface of the temple base 61; finally, the temple cover plate 62 is covered on the temple base 61. The temple cover plate 62 can be fixed by snap-fit ​​or glue, so that the cover plate completely covers the first screw 64 and the internal structure of the temple base 61, only exposing the flat outer surface of the temple 6.

[0086] In this embodiment, the first connecting seat 11 adopts a dual fixing method of embedded + screw locking, which effectively restricts the multi-directional displacement of the first connecting seat 11. Even under harsh scenarios such as frequent folding and external impact, it can still maintain a stable connection between the connecting seat and the temple 6, avoiding misalignment of the threading channel and failure of the seal due to loose connection, and ensuring the stable performance of the waterproof hinge. The temple cover plate 62 covers the first screw 64 and the internal structure, making the temple 6 flat and without protrusions, improving the product design; at the same time, the sealing fit between the cover plate and the bottom shell reduces the infiltration path of external foreign objects and liquids, further strengthening the protective performance of the temple 6, and working together with the waterproof hinge to build a more comprehensive protection system.

[0087] In one embodiment, reference is made to Figure 10 The first connecting seat 11 includes a snap-fit ​​portion 112 and a threaded locking portion 113 disposed opposite to each other at both ends of the first connecting seat 11. The snap-fit ​​portion 112 snaps into the end of the temple base 61 near the frame 7. The threaded locking portion 113 is configured to cooperate with the first screw 64. The temple cover plate 62 covers the threaded locking portion 113.

[0088] The snap-fit ​​part 112 is located at the end of the first connecting seat 11 near the frame 7. It is a raised snap-fit ​​structure, and its shape is precisely matched with the corresponding slot of the temple base 61. The threaded locking part 113 is located at the other end of the first connecting seat 11 away from the frame 7. It has a light hole inside that matches the first screw 64. After the first screw 64 passes through the threaded locking part 113, it is threaded and locked onto the threaded hole of the temple base 61. The snap-fit ​​part 112 and the threaded locking part 113 are symmetrically distributed along the length of the first connecting seat 11 to ensure that the connecting seat is subjected to balanced force after fixing, without the risk of skewing. During assembly, the snap-fit ​​part 112 of the first connecting seat 11 is aligned with the snap-fit ​​groove of the temple base 61, and one end of the connecting seat can be fixed without the need for additional tooling. Then, the other end of the connecting seat can be fixed by simply passing the first screw 64 through the threaded locking part 113 and locking it onto the temple base 61. This forms an assembly process of pre-fixing one end and strong locking the other end, which greatly simplifies the operation steps and improves the assembly efficiency.

[0089] In this embodiment, the quick positioning of the snap-fit ​​part 112 reduces the alignment and adjustment time required for traditional pure screw fixing. Operators can complete the initial fixing without supporting the connector with both hands. Subsequent assembly can be completed with just a single first screw 64. Compared to multi-screw fixing or pure snap-fit ​​fixing, the assembly steps are fewer, making it suitable for mass production on assembly lines. At the same time, the dual fixing of snap-fit ​​and screw is complementary. The snap-fit ​​part 112 can buffer instantaneous impact forces (such as vibrations from accidental drops), preventing the screw from stripping due to excessive instantaneous force. The screw locking compensates for the loosening problem caused by elastic fatigue of the snap after long-term use. The combination of the two allows the connector to remain stable under scenarios such as frequent folding and external impact, effectively preventing misalignment of the threading channel and failure of the sealing plug due to loose connection.

[0090] In one embodiment, combined with Figure 11 and Figure 12 The frame 7 includes a first frame shell 71 and a second frame shell 72 that are adapted to each other. The second connecting seat 21 is embedded in the first frame shell 71 and locked to the first frame shell 71 by the second screw 74. The second frame shell 72 covers the first frame shell 71 and covers the second screw 74.

[0091] The first frame housing 71 serves as the basic support structure for the frame 7, with a pre-reserved slot for mounting the lens. It also has a second mounting opening at the corresponding position of the second connector 21, matching the shape of the second connector 21. The first frame housing 71 also contains a cavity for mounting second components 73 (such as a camera module, display driving circuit, or sensor). The second frame housing 72 is a cover structure that conforms to the shape of the first frame housing 71. When closed, it completely covers the cavity of the first frame housing 71 and the second screw 74, forming a complete outer surface of the frame 7. Optionally, a sealing strip groove is provided at the joint edge of the first frame housing 71 and the second frame housing 72 to accommodate a waterproof strip and improve sealing.

[0092] In this embodiment, during assembly, the first frame housing 71 serves as the basic assembly carrier, independently enabling the installation of the second component 73 and the embedded fixing of the second connector 21. Operators are not affected by the obstruction of the second frame housing 72 and can accurately position components and tighten the second screw 74 in an open space, significantly reducing assembly difficulty. If subsequent repairs are needed (such as replacing the camera module or inspecting the conductor), only the second frame housing 72 needs to be disassembled to expose the internal structure, without disassembling the waterproof hinge or the entire frame 7. This avoids the destructive disassembly required for traditional integrated frame 7, shortening repair time and reducing repair costs. After the second frame housing 72 is closed, it completely covers the second screw 74 and the internal structure, eliminating any cosmetic defects caused by exposed screw heads, keeping the outer surface of the frame 7 smooth and flat, and optimizing the product design.
