Description

Technical Field

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

[0002] With the rapid development of technologies such as artificial intelligence and virtual reality, smart glasses products such as AI glasses and VR glasses have been widely used in various fields such as consumer electronics, industrial production, and healthcare, becoming important terminal devices for human-computer interaction. To meet users' needs for convenient operation of the devices, existing smart glasses products usually have physical switch buttons (such as power buttons, function switch buttons, etc.) in easily accessible locations such as the frame and temples, for core operations such as powering on / off, switching modes, and activating / deactivating functions.

[0003] To enable the installation and activation of the power button, the smart glasses' casing needs to have corresponding mounting holes to accommodate the button, with the button partially exposed through these holes for easy user operation. However, in real-world use, smart glasses are worn on the user's head for extended periods in complex and variable environments. Firstly, sweat generated during wear continuously contacts the button mounting area, and the salt and oil in the sweat can easily seep into the device through the gaps between the button and the hole. Secondly, users may encounter rain outdoors or use the glasses in high-humidity environments (such as the rainy season or coastal areas), where moisture condenses on the device's surface and gradually seeps into the gaps. Since smart glasses integrate numerous precision electronic components (such as processors, sensors, circuit boards, and batteries), these components are extremely sensitive to liquids. When sweat, rain, and ambient moisture seep into the device through the gaps between the button and the hole, it can easily cause short circuits, corrosion, performance degradation, and even device malfunction, severely impacting the product's reliability and lifespan. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a smart glasses that can solve the problem of water ingress at the button mounting area of ​​related smart glasses.

[0005] To achieve the above objectives, this application adopts the following technical solution: A smart pair of glasses, comprising: The housing has an internal mounting cavity and at least one side wall has a button hole; An electronic switch is installed inside the mounting cavity and aligned with the button hole; The button includes a connected button plate and a connecting post. The button plate is located outside the housing, and the connecting post extends through the button hole into the mounting cavity and is aligned with the electronic switch. A sealing ring is fitted over the connecting post, and the sealing ring seals and fills the gap between the connecting post and the button hole. An ejector elastic member is installed between the button plate and the housing, and the ejector elastic member provides an ejection force to the button plate; An anti-detachment component is located within the mounting cavity and connected to the connecting post to prevent the connecting post from detaching from the key hole.

[0006] In the smart glasses solution provided in this embodiment, the full-circumferential dynamic sealing design of the sealing ring can continuously adhere to the outer wall of the connecting post and the inner wall of the button hole throughout the entire process of button pressing and resetting. This fundamentally blocks the path of sweat, rainwater, and moisture seeping into the mounting cavity, effectively preventing short circuits and corrosion of internal electronic components, significantly improving product reliability and service life, and making it suitable for complex usage scenarios such as outdoor and high humidity environments. At the same time, this structure relies on only a few simple components to achieve waterproof, reset, and anti-detachment functions, without the need for complex waterproof cavities or multi-layer sealing designs. It occupies little installation space, which not only conforms to the design trend of lightweight and miniaturized smart glasses, but also simplifies the assembly process and reduces manufacturing costs. Furthermore, the ejector spring ensures that the button returns to its original position quickly and smoothly after being pressed, providing a comfortable operating feel. The anti-detachment component prevents the button from falling off due to ejection force or accidental pulling, ensuring structural stability during long-term use. Moreover, the overall design is not dependent on a specific housing shape or electronic switch type. The button hole can be flexibly set in the frame, temple, or other positions. The material and size of the sealing ring can also be adjusted according to the usage scenario, resulting in extremely strong compatibility and adaptability. In addition, the selection of aging-resistant and wear-resistant component materials not only extends the product's service life but also significantly reduces maintenance costs due to the high versatility of the components, requiring only the replacement of the sealing ring or spring.

[0007] In one embodiment, a circuit board is disposed inside the housing, and an electronic switch is disposed on the side wall of the circuit board, wherein the pressing direction of the electronic switch is perpendicular to the thickness direction of the circuit board.

[0008] In this embodiment, the electronic switch is located on the side wall of the circuit board and the pressing direction is perpendicular to the thickness direction of the circuit board. On the one hand, this can significantly optimize the internal space utilization of the smart glasses housing, greatly reduce space occupation, and effectively compress the width of the frame or the thickness of the temples, which is more in line with the lightweight and miniaturized design requirements of smart glasses. At the same time, this design fully adapts to the thin plate structure characteristics of the circuit board. The pressing pressure is applied to the side wall direction of the circuit board, which has stronger bending and compressive strength. This can effectively avoid the risk of circuit board bending damage that is easily caused by pressing in traditional designs. The protection effect on thin circuit boards is particularly obvious, and the probability of related failures is significantly reduced.

[0009] In one embodiment, the sidewall of the circuit board is provided with a mounting recess, and the electronic switch is embedded in the mounting recess.

[0010] In this embodiment, the circuit board sidewall features a mounting recess for the embedded electronic switch. This design optimizes the internal space of the smart glasses. In traditional designs, the electronic switch protrudes from the circuit board sidewall, requiring additional space. This solution embeds the switch partially or completely into the circuit board via the recess, significantly reducing vertical space occupation and allowing for further reduction in frame or temple thickness, thus improving fit. Furthermore, it significantly enhances structural stability. The mounting recess provides lateral mechanical restraint for the electronic switch, and combined with adhesive bonding, it greatly reduces the risk of loosening or shifting of the switch under vibration or frequent pressing.

[0011] In one embodiment, the housing has a recessed portion that sinks into the mounting cavity corresponding to the mounting position of the button, and a groove is formed on the outer side of the recessed portion, which can provide movement space for the button plate that is pressed; the side wall of the circuit board has a relief recess corresponding to the recessed portion, and the mounting recess is located at the bottom of the relief recess.

[0012] In this embodiment, both space utilization and wearing experience are optimized. The recessed part of the shell embeds the button panel into the recessed groove, avoiding the problem of skin irritation caused by the buttons protruding from the shell surface and improving the fit and comfort. At the same time, the nested design of the recessed part and the avoidance recess allows the shell and the circuit board to be installed in a compact space without interference. All components can be accommodated without increasing the size of the shell, and more layout space is reserved for other components in the installation cavity, which is convenient for functional expansion.

[0013] In one embodiment, the button panel is connected to two ejector elastic members, which are symmetrically arranged on both sides of the connecting post.

[0014] In this embodiment, a dual-symmetrical ejector elastic element scheme is adopted, which significantly improves the stability of pressing and resetting. The two ejector elastic elements are symmetrically arranged on both sides of the connecting post. When pressing, the button plate is subjected to uniform force, avoiding the displacement of the connecting post or wear of the sealing ring caused by unilateral tilting. When resetting, the symmetrical ejector force is released simultaneously to ensure that the button plate returns to its position smoothly, eliminating the problem of jamming or displacement. At the same time, the linear movement of the connecting post makes the electronic switch triggering more accurate, reducing the risk of operation failure, and improving the smoothness of the operation feel.

[0015] In one embodiment, the outer wall of the housing is provided with a mounting groove, one end of the ejector elastic member is fixed in the mounting groove, and the other end abuts against the button plate.

[0016] In this embodiment, the mounting groove provides a dedicated fixing space for the elastic element, preventing the elastic element from tilting or slipping laterally during pressing and resetting. Combined with the symmetrical layout, the button plate is subjected to more even force, and the connecting column always moves in a straight line along the axis, which reduces wear on one side of the sealing ring, extends the waterproof life, and ensures accurate triggering of the electronic switch, reducing the risk of operational failure.

[0017] In one embodiment, a first annular groove is provided on the periphery of the connecting post, and the sealing ring is fitted into the first annular groove to restrict the axial movement of the sealing ring relative to the connecting post.

[0018] In this embodiment, the sealing ring is fitted into the first annular groove. The axial limiting effect of the first annular groove keeps the sealing ring in a preset position. No matter how the connecting post moves, the relative position between the sealing ring and the connecting post remains unchanged, always filling the gap between the connecting post and the side wall of the key hole, forming a stable dynamic seal. At the same time, the radial deformation of the sealing ring caused by the groove limiting is more uniform, and the fit is higher, which can effectively block the infiltration path of liquids such as sweat and rainwater.

[0019] In one embodiment, the end of the connecting post away from the keypad is further provided with a second annular groove, and the anti-disengagement component is a retaining spring that fits into the second annular groove.

[0020] In this embodiment, the elastic fit design of the retaining spring and the second annular groove provides a more stable installation compared to traditional anti-loosening components. It is less prone to loosening due to vibration or frequent pressing, and can stably prevent the connecting post from detaching from the button hole for a long time, avoiding button detachment failure. In addition, the retaining spring installation does not require complicated tools; it can be quickly snapped into the groove using only special retaining spring pliers, simplifying the assembly process. Furthermore, the standardized retaining spring and second annular groove design reduces the probability of assembly errors.

[0021] In one embodiment, the housing includes a temple housing and a frame housing, which are connected by a waterproof hinge. The waterproof hinge includes 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 connected to the temple housing and has a first through hole for communicating between the inner and outer areas of the temple housing. The second hinge support includes a second connecting seat and a second hinge portion connected together. The second connecting seat is connected to the frame housing and has a second through hole for communicating between the inner and outer areas of the frame housing. The second hinge portion is hinged to the first hinge portion. The first sealing plug is fitted into and installed in the first through hole and has a first wire through hole. The second sealing plug is fitted into and installed in the second through hole and has a second wire through hole. One end of a flexible conductor is connected to a first component inside the temple housing, and the other end extends out of the temple housing through the first sealing plug and extends into the frame housing through the second sealing plug to connect to a second component inside the frame housing.

[0022] The waterproof hinge in this embodiment achieves a harmonious balance between structural sealing and functional practicality through the synergistic design of a double-hinge support and double-sealing plugs. The core benefits 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 conductor forms a double sealing barrier, effectively preventing sweat, rainwater, and environmental moisture from seeping into the frame or temple through the perforation gap at the hinge. This avoids the problem of short circuits, corrosion, functional failure, or permanent damage to internal electronic components due to water exposure, thus greatly improving the waterproof performance, reliability, and lifespan of smart glasses.

[0023] 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, with the two first hinge bosses respectively hinged to two opposite sides of the second hinge boss. 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 passage.

[0024] In this embodiment, the wiring channel completely encloses the flexible conductor from the inner cavity of the temple housing to the inner cavity of the frame housing 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 housing 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 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.

Detailed Implementation

[0028] 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.

[0029] 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.

[0030] 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.

[0031] With the rapid development of technologies such as artificial intelligence and virtual reality, smart glasses products such as AI glasses and VR glasses have been widely used in various fields such as consumer electronics, industrial production, and healthcare, becoming important terminal devices for human-computer interaction. To meet users' needs for convenient operation of the devices, existing smart glasses products usually have physical switch buttons (such as power buttons, function switch buttons, etc.) in easily accessible locations such as the frame and temples, for core operations such as powering on / off, switching modes, and activating / deactivating functions.

[0032] To enable the installation and activation of the power button, the smart glasses' casing needs to have corresponding mounting holes to accommodate the button, with the button partially exposed through these holes for easy user operation. However, in real-world use, smart glasses are worn on the user's head for extended periods in complex and variable environments. Firstly, sweat generated during wear continuously contacts the button mounting area, and the salt and oil in the sweat can easily seep into the device through the gaps between the button and the hole. Secondly, users may encounter rain outdoors or use the glasses in high-humidity environments (such as the rainy season or coastal areas), where moisture condenses on the device's surface and gradually seeps into the gaps. Since smart glasses integrate numerous precision electronic components (such as processors, sensors, circuit boards, and batteries), these components are extremely sensitive to liquids. When sweat, rain, and ambient moisture seep into the device through the gaps between the button and the hole, it can easily cause short circuits, corrosion, performance degradation, and even device malfunction, severely impacting the product's reliability and lifespan.

[0033] To overcome the above technical problems, refer to Figures 1-5 This application provides a smart glasses embodiment, including: The housing has an internal mounting cavity and at least one side wall has a button hole 111. An electronic switch 71 is installed in the mounting cavity and aligned with the button hole 111; Button 3 includes a connected button plate 31 and a connecting post 32. The button plate 31 is located outside the housing, and the connecting post 32 extends through the button hole 111 into the mounting cavity and is aligned with the electronic switch 71. A sealing ring 4 is fitted over the connecting post 32, and the sealing ring 4 seals and fills the gap between the connecting post 32 and the key hole 111. An ejector elastic member 5 is installed between the button plate 31 and the housing, and the ejector elastic member 5 provides an ejection force to the button plate 31; The anti-detachment component 6 is located inside the mounting cavity and connected to the connecting post 32 to prevent the connecting post 32 from detaching from the key hole 111.

[0034] The housing, serving as the external encapsulation and internal component mounting carrier for the smart glasses, has an independent mounting cavity to provide physical protection for the internal components. The smart glasses structure includes a frame and temples. The housing comprises a frame housing 2 and a temple housing 1. When an electronic switch 71 is installed within the frame housing 2, the waterproof button 3 structure of this solution can be used; similarly, when the electronic switch 71 is installed within the temple housing 1, the waterproof button 3 structure of this solution can also be used. The button hole 111 on the side wall of the housing provides a through channel for the button 3 connecting post 32. The hole diameter matches the outer diameter of the connecting post 32, ensuring smooth reciprocating movement of the connecting post 32 while also providing a reasonable gap for the sealing ring 4.

[0035] The electronic switch 71 is fixed in the mounting cavity and precisely aligned with the button hole 111. It is the core of the user operation function trigger (such as power on / off, mode switching). Its installation position corresponds to the end of the connecting post 32, ensuring that the force can be effectively transmitted when the button 3 is pressed, so as to realize the reliable triggering of the switch.

[0036] Button 3 includes an integrated button plate 31 and a connecting post 32. The button plate 31 is located on the outside of the housing, providing a pressing surface for the user. Its size is larger than the button hole 111, which can prevent fingers from contacting the gap when pressing, and at the same time provide a mounting support surface for the ejector elastic element 5. The connecting post 32 serves as the core of force transmission. One end is fixedly connected to the button plate 31, and the other end extends into the mounting cavity through the button hole 111 and is aligned with the electronic switch 71. Its length design ensures that the electronic switch 71 can be accurately triggered when the button 3 is pressed to the end of its stroke, without interfering with other components in the mounting cavity.

[0037] The sealing ring 4 is fitted onto the outside of the connecting post 32 and seals the gap between the connecting post 32 and the button hole 111. The material is preferably silicone or fluororubber that is sweat-resistant, aging-resistant and elastic (suitable for long-term wear scenarios of smart glasses). During installation, the sealing ring 4 must fit tightly against the outer wall of the connecting post 32 and the inner wall of the button hole 111 to form a circumferential full-coverage seal, blocking the path of sweat, rainwater and moisture to seep in from the gap.

[0038] The ejector elastic element 5 is installed between the keypad 31 and the outer wall of the housing. It is preferably a small compression spring or elastic rubber ring. Its initial state is naturally extended or slightly compressed, and it continuously provides an ejector force away from the housing to the keypad 31. The installation position of the elastic element should avoid the key hole 111 area to avoid affecting the sealing effect. At the same time, it should ensure that the ejector force is evenly applied to the keypad 31 to ensure that the key 3 can be quickly and smoothly reset after being pressed.

[0039] The anti-detachment component 6 is located inside the mounting cavity and is fixedly connected to one end of the connecting post 32 that extends into the mounting cavity (such as by threaded connection, snap-fit ​​connection or integral molding). Its lateral dimension is larger than the diameter of the button hole 111. The anti-detachment component 6 can limit the connecting post 32 from detaching from the housing, and prevent the button 3 from falling off as a whole due to the ejection force of the ejector elastic component 5 or accidental pulling, thus ensuring structural stability.

[0040] When the user applies pressure to the button plate 31 pointing inwards towards the housing, the button plate 31 drives the connecting post 32 to move along the button hole 111 into the mounting cavity, compressing the elastic element 5 (storing elastic potential energy). When the end of the connecting post 32 contacts the electronic switch 71 and applies sufficient pressure, the electronic switch 71 is triggered, realizing the corresponding function operation (such as powering on or switching modes). Throughout the entire movement stroke of the button 3 (pressed state and reset state), the sealing ring 4 is always in close contact with the outer wall of the connecting post 32 and the inner wall of the button hole 111, forming a dynamic seal, effectively isolating sweat, rainwater, water vapor, etc., preventing them from entering the mounting cavity through the gap between the connecting post 32 and the button hole 111, protecting the internal electronic switch 71 and other components.

[0041] In the smart glasses solution provided in this embodiment, the full-circumferential dynamic sealing design of the sealing ring 4 can continuously adhere to the outer wall of the connecting post 32 and the inner wall of the button hole 111 throughout the entire process of pressing and resetting the button 3. This fundamentally blocks the path of sweat, rainwater, and moisture seeping into the installation cavity, effectively preventing short circuits and corrosion of internal electronic components, significantly improving product reliability and service life, and adapting to complex usage scenarios such as outdoor and high humidity. At the same time, this structure relies on only a few simple components to achieve waterproof, reset, and anti-detachment functions, without the need for complex waterproof cavities or multi-layer sealing designs, occupying little installation space. This not only conforms to the design trend of lightweight and miniaturized smart glasses, but also simplifies the assembly process and reduces manufacturing costs. In addition, the ejector elastic element 5 ensures that the button 3 can quickly and smoothly reset after being pressed, providing a comfortable operating feel. The anti-detachment element 6 prevents the button 3 from falling off due to ejection force or accidental pulling, ensuring structural stability during long-term use. Moreover, the overall design does not depend on a specific housing shape or electronic switch 71 type. The button hole 111 can be flexibly set in the frame, temple, or other positions. The material and size of the sealing ring 4 can also be adjusted according to the usage scenario, making it highly compatible and adaptable. In addition, the selection of aging-resistant and wear-resistant component materials not only extends the product's service life, but also, due to the high versatility of the components, subsequent maintenance only requires replacing the sealing ring 4 or the elastic element, significantly reducing maintenance costs.

[0042] In one embodiment, reference is made to Figure 4 and Figure 5 The housing contains a circuit board 7, and the electronic switch 71 is disposed on the side wall of the circuit board 7. The pressing direction of the electronic switch 71 is perpendicular to the thickness direction of the circuit board 7.

[0043] The circuit board 7 is typically thin and has two relatively large mounting surfaces (front and back), with its thickness direction being the distance between the two mounting surfaces (usually 1-2 mm). In this design, the circuit board 7 is fixed in the mounting cavity within the housing, with its thickness-direction sidewall (i.e., the narrow sidewall with an area much smaller than the mounting surface) facing the button hole 111, ensuring that the electronic switch 71 can be precisely aligned with the connecting post 32 after installation. Compared to the traditional design where the electronic switch 71 is located on the mounting surfaces (front / back) of the circuit board 7, this layout significantly reduces the space occupied by the circuit board 7 in the thickness direction within the mounting cavity.

[0044] Furthermore, the electronic switch 71 can be fixed to the side wall of the circuit board 7 by surface mounting or plug-in. Its trigger end (the part that needs to be pressed) extends in a direction perpendicular to the thickness of the circuit board 7 and is collinear with the axis of the connecting post 32 of the button 3. For example, if the thickness direction of the circuit board 7 is left-right (i.e., the two mounting planes face left and right respectively), then the pressing direction of the electronic switch 71 is up-down, which matches the up-down extension direction of the connecting post 32 from the outside to the inside of the housing, thus avoiding offset during force transmission. At the same time, this mounting method allows the pressing force to act directly on the side wall of the circuit board 7, rather than the traditional mounting plane, making full use of the mechanical performance differences of the circuit board 7 in different directions. When the user presses the button 31, the pressing force is directly transmitted to the trigger end of the electronic switch 71 through the connecting post 32 in a direction perpendicular to the thickness of the circuit board 7. The force transmission path is completely straight, without any bending or offset. In traditional designs, the electronic switch 71 is located on the mounting plane of the circuit board 7. When pressed, the pressing force acts on the mounting plane along the thickness direction of the circuit board 7, which can easily cause the thin-plate-shaped circuit board 7 to bend and deform along the thickness direction. However, in this solution, the pressing force acts on the side wall of the circuit board 7, which is consistent with the length or width direction of the thin-plate-shaped structure of the circuit board 7. The bending and compressive resistance of the circuit board 7 in this direction is significantly enhanced, which can effectively avoid the risk of bending and damage to the circuit board 7 caused by pressing.

[0045] In this embodiment, the electronic switch 71 is located on the side wall of the circuit board 7 and the pressing direction is perpendicular to the thickness direction of the circuit board 7. On the one hand, it can significantly optimize the internal space utilization of the smart glasses housing, greatly reduce space occupation, and effectively compress the frame width or temple thickness, which is more in line with the lightweight and miniaturized design requirements of smart glasses. At the same time, this design fully adapts to the thin plate structure characteristics of the circuit board 7. The pressing pressure is applied to the side wall direction of the circuit board 7, which has stronger bending and compressive resistance. It can effectively avoid the risk of bending damage to the circuit board 7 that is easy to cause when pressing in traditional designs. The protection effect on the thin circuit board 7 is particularly obvious, and the probability of related failures is significantly reduced.

[0046] In one embodiment, reference is made to Figure 5 and Figure 9 The sidewall of the circuit board 7 is provided with a mounting recess 73, and the electronic switch 71 is embedded in the mounting recess 73.

[0047] Mounting recess 73 is provided on the side wall of circuit board 7, and its shape matches the shape of electronic switch 71.

[0048] In this embodiment, the sidewall of the circuit board 7 has a mounting recess 73, and the electronic switch 71 is embedded in it. On the one hand, this can optimize the internal space of the smart glasses to the extreme. In traditional designs, the electronic switch 71 protrudes from the sidewall of the circuit board 7, requiring additional space. However, this solution embeds part or all of the switch into the circuit board 7 through the recess, greatly reducing the vertical space occupied. This can further reduce the thickness of the frame or temples and improve the fit. On the other hand, it can significantly enhance the structural stability. The mounting recess 73 can provide lateral mechanical restraint for the electronic switch 71. Combined with adhesive fixation, it can greatly reduce the risk of the switch loosening or shifting under vibration or frequent pressing.

[0049] In one embodiment, combined with Figures 5-8 The housing has a recessed portion 11 that sinks into the mounting cavity corresponding to the mounting position of the button 3. A groove 112 is formed on the outer side of the recessed portion 11. The groove 112 can provide movement space for the button plate 31 that is pressed. The side wall of the circuit board 7 has a relief recess 72 corresponding to the recessed portion 11. The mounting recess 73 is located at the bottom of the relief recess 72.

[0050] The recessed portion 11 is an area formed by the side wall of the housing recessed into the mounting cavity. Its depth is adapted to the thickness of the keypad 31, and the outline of the groove 112 formed on the outer side matches the shape of the keypad 31 (such as circular or square). The clearance recess 72 is formed on the side wall of the circuit board 7, and its recess direction is consistent with the recess direction of the recessed portion 11 of the housing. Its depth and width need to cover the projection range of the recessed portion 11 in the mounting cavity to avoid interference between the circuit board 7 and the recessed portion 11. The mounting recess 73 is set at the bottom of the clearance recess 72, continuing the embedded mounting design of the electronic switch 71. The position of the mounting recess 73 needs to be precisely aligned with the center of the recessed portion 11 (i.e., the position of the key hole 111) to ensure that the connecting post 32 can directly contact the trigger end of the electronic switch 71 through the key hole 111 and the inner space of the recessed portion 11.

[0051] In this embodiment, both space utilization and wearing experience are optimized. The recessed part 11 of the shell allows the button plate 31 to be embedded in the recessed groove 112, avoiding the problem of skin irritation caused by the button 3 protruding from the shell surface and improving the fit and comfort. At the same time, the nested design of the recessed part 11 and the avoidance recess 72 allows the shell and the circuit board 7 to be installed in a compact space without interference. All components can be accommodated without increasing the size of the shell, and more layout space is reserved for other components in the installation cavity, which is convenient for functional expansion.

[0052] In one embodiment, the button plate 31 is connected to two ejector elastic members 5, which are symmetrically arranged on both sides of the connecting post 32.

[0053] Two ejector elastic elements 5 (preferably small compression springs) are respectively connected to the side of the button plate 31 facing the housing, and are symmetrically distributed with the axis of the connecting post 32 as the axis of symmetry. One end of the elastic element can be fixed to the button plate 31 by buckle, adhesive or groove, and the other end abuts against the bottom of the recess 112 to ensure that there is no looseness after installation. The length of the elastic element needs to be adapted to the depth of the recess 112, so that it can support the button plate 31 to remain in the initial position in the recess 112 under natural state, and can be compressed synchronously when pressed. When the user presses the button plate 31, the two symmetrical elastic elements are compressed synchronously. Due to the symmetrical arrangement, the compressive force on the button plate 31 is evenly distributed on both sides of the connecting post 32, avoiding the tilting of the button plate 31 caused by the force on one side. After the button 3 is released, the two elastic elements release elastic potential energy synchronously, apply symmetrical ejector force to the button plate 31, push the button plate 31 to return to its original position smoothly, prevent the return offset or jamming caused by the uneven elastic force of the elastic element on one side, and ensure that the button plate 31 always remains in close alignment with the recess 112.

[0054] In this embodiment, a dual-symmetric ejector elastic element 5 is adopted, which significantly improves the stability of pressing and resetting. The two ejector elastic elements 5 are symmetrically arranged on both sides of the connecting post 32. When pressing, the button plate 31 is subjected to uniform force, avoiding the offset of the connecting post 32 or the wear of the sealing ring 4 caused by unilateral tilting. When resetting, the symmetrical ejector force is released simultaneously to ensure that the button plate 31 returns to its position smoothly, eliminating the problem of jamming or offset. At the same time, the linear movement of the connecting post 32 makes the electronic switch 71 trigger more accurately, reducing the risk of operation failure, and improving the smoothness of the operation feel.

[0055] In one embodiment, reference is made to Figure 7 The outer wall of the housing is provided with a mounting groove 113, one end of the ejector elastic member 5 is fixed in the mounting groove 113, and the other end abuts against the button plate 31.

[0056] The inner wall of the mounting groove 113 may be provided with small protrusions to enhance the friction with the elastic element and prevent the elastic element from shifting. If the elastic element is a spring, a positioning post may also be provided in the groove for the spring to be sleeved and fixed, further improving stability. One end of the ejector elastic element 5 is fixed in the mounting groove 113, and the other end abuts against the button plate 31. When the button plate 31 is pressed, the elastic element is compressed axially along the mounting groove 113. The limiting effect of the mounting groove 113 ensures that the elastic element only undergoes axial deformation, avoiding lateral tilting. During the compression process, the elastic force of the elastic element is evenly transmitted to the button plate 31 axially. With the symmetrical layout, this further ensures that the button plate 31 is under balanced force and has no tilting or offset.

[0057] In this embodiment, the mounting groove 113 provides a dedicated fixing space for the elastic element, preventing the elastic element from tilting or slipping laterally during pressing and resetting. Combined with the symmetrical layout, the button plate 31 is subjected to more even force, and the connecting column 32 always moves in a straight line along the axis, which not only reduces the wear of the sealing ring 4 on one side and extends the waterproof life, but also ensures the precise triggering of the electronic switch 71 and reduces the risk of operational failure.

[0058] In one embodiment, reference is made to Figure 10 and Figure 11 The connecting post 32 is provided with a first annular groove 321 on its periphery, and the sealing ring 4 is fitted into the first annular groove 321 to restrict the axial movement of the sealing ring 4 relative to the connecting post 32.

[0059] During installation, the sealing ring 4 is radially compressed and inserted into the first annular groove 321. After insertion, the sealing ring 4 is circumferentially fixed in the groove and cannot move axially along the connecting column 32. At the same time, the outer diameter of the sealing ring 4 needs to be slightly larger than the inner diameter of the key hole 111 to ensure that the sealing ring 4 can fit tightly against the inner wall of the key hole 111 after being inserted into the key hole 111, forming an initial sealing pressure. The position of the first annular groove 321 must ensure that the sealing ring 4 is always within the range of the key hole 111 (regardless of whether the key 3 is pressed or reset) to avoid sealing failure due to axial displacement.

[0060] In this embodiment, the sealing ring 4 is fitted into the first annular groove 321. The axial limiting effect of the first annular groove 321 keeps the sealing ring 4 in a preset position. No matter how the connecting post 32 moves, the relative position between the sealing ring 4 and the connecting post 32 remains unchanged, always filling the gap between the connecting post 32 and the side wall of the button hole 111, forming a stable dynamic seal. At the same time, the radial deformation of the sealing ring 4 caused by the groove limiting is more uniform, and the fit is higher, which can effectively block the infiltration path of liquids such as sweat and rainwater.

[0061] In one embodiment, the end of the connecting post 32 away from the button plate 31 is further provided with a second annular groove 322, and the anti-disengagement member 6 is a retaining spring that fits into the second annular groove 322.

[0062] The anti-detachment component 6 is an elastic retaining ring (such as a C-type retaining ring). The inner diameter of the retaining ring is slightly smaller than the outer diameter of the ungrooved part of the connecting post 32. During installation, it is inserted into the second annular groove 322 by radial expansion. After being inserted, the retaining ring forms a circumferential fixation in the groove. Its outer protruding part can abut against the inner wall of the housing mounting cavity, restricting the connecting post 32 from moving out of the housing.

[0063] In this embodiment, the elastic fit design of the retaining spring and the second annular groove 322 provides a more stable installation compared to the traditional anti-loosening component 6. It is less prone to loosening due to vibration or frequent pressing, and can stably prevent the connecting post 32 from disengaging from the button hole 111 for a long time, thus avoiding the failure of the button 3 to fall off. In addition, the retaining spring can be installed without complicated tools, and can be quickly snapped into the groove with special retaining spring pliers, simplifying the assembly process. Furthermore, the standardized design of the retaining spring and the second annular groove 322 reduces the probability of assembly errors.

[0064] On the other hand, current smart glasses require the integration of various electronic components such as camera modules, processors, memory, speakers, and batteries within the frame and temples. Signal transmission and circuit connectivity between the frame and temples typically utilize flexible printed circuit boards (FPCs) connected via the hinges. 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 must be created in the hinge body and corresponding mounting locations. However, in practical use cases, smart glasses are worn on the user's head for extended periods, inevitably coming into contact with sweat, rain, and ambient humidity. Since the holes / gaps at the hinges are designed to accommodate FPC installation, their sealing performance is structurally limited and cannot be completely closed. This allows sweat to easily penetrate from the user's scalp to the hinge surface, and rain or other environmental liquids may 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 frames and temples are sensitive to moisture. Once liquid seeps in, it can cause short circuits and corrosion, as well as abnormal signal transmission and malfunction. In severe cases, it can cause permanent damage to the electronic components, significantly reducing the lifespan and reliability of smart glasses.

[0065] To overcome the above technical problems, in one embodiment, reference is made to... Figures 12-18The housing includes a temple housing 1 and a frame housing 2. The temple housing 1 and the frame housing 2 are connected by a waterproof hinge 8. The waterproof hinge 8 includes a first hinge support 81, a second hinge support 82, a first sealing plug 83, and a second sealing plug 84. The first hinge support 81 includes a first connecting seat 811 and a first hinge portion 812 connected together. The first connecting seat 811 is connected to the temple housing 1 and has a first through hole 8111 for communicating between the inner and outer areas of the temple housing 1. The second hinge support 82 includes a second connecting seat 821 and a second hinge portion 822 connected together. The second connecting seat 821 is connected to the frame housing 2 and has a through hole 821 for communicating between the frame housing 2 and the frame housing 2. The second through hole 211 in the inner and outer regions, the second hinge part 822 is hinged to the first hinge part 812; the first sealing plug 83 is fitted and installed in the first through hole 8111, and the first sealing plug 83 is provided with a first wire passage hole 831; the second sealing plug 84 is fitted and installed in the second through hole 211, and the second sealing plug 84 is provided with a second wire passage hole 841; one end of the flexible connecting conductor 9 is connected to the first component inside the temple housing 1, and the other end extends out of the temple housing 1 through the first sealing plug 83, and extends into the frame housing 2 through the second sealing plug 84 to connect to the second component inside the frame housing 2.

[0066] In the specific structure, during application, the temple includes a temple housing 1. The temple housing 1 has a first cavity to provide mounting support and protection for the first component inside. In this embodiment, regarding the temple, the space inside the first cavity is called the interior, and the space outside the temple is called the exterior. Therefore, the first through hole 8111 connecting the interior and exterior of the temple is a through hole structure connecting the first cavity and the external environment. The end of the temple near the frame is connected to the first hinge support 81. To allow the flexible conductor 9 to pass out from the interior of the first cavity, a first mounting port corresponding to the mounting of the first hinge support 81 is usually provided on the temple housing. This allows the first hinge support 81 to be installed in the first mounting port, which can be completely sealed with the first sealing plug 83. At the same time, the flexible conductor 9 can extend to the outside of the temple through the first mounting port and the first wire hole 831 of the first sealing plug 83.

[0067] The eyeglass frame includes an eyeglass frame housing 2. The eyeglass frame housing 2 is provided with a second cavity to provide mounting support and protection for the second components inside. In this embodiment, regarding the eyeglass frame, the space inside the second cavity is called the interior, and the space outside the eyeglass frame is called the exterior. Therefore, the second through hole 211 connecting the interior and exterior of the eyeglass frame is a through hole structure connecting the second cavity and the external environment. The end of the eyeglass frame near the temple is connected to the second hinge support 82. In order to allow the flexible conductor 9 to pass out from the interior of the second cavity, a second mounting port corresponding to the mounting of the second hinge support 82 is usually provided on the eyeglass frame housing. This allows the second hinge support 82 to be installed in the second mounting port, so that the second mounting port can be completely sealed with the second sealing plug 84. At the same time, the flexible conductor 9 can extend to the exterior of the eyeglass frame through the second mounting port and the second wire hole 841 of the second sealing plug 84.

[0068] The flexible conductor 9 is used to connect the temple and the first and second components inside the frame, enabling the transmission of current and electrical signals between the first and second components. The flexible conductor 9 can be a flexible circuit board 7, a wire, etc., which can bend and stretch with the rotation of the temple.

[0069] The first hinge portion 812 and the second hinge portion 822 are hinged together, which can be achieved by connecting structures such as pins and pivots. During the rotation of the temple, the first hinge portion 812 and the second hinge portion 822 rotate relative to the pins and pivots.

[0070] The first sealing plug 83 is a customized fit structure, with its shape precisely matching the inner wall contour of the first through hole 8111, ensuring no obvious gap between it and the inner wall of the first through hole 8111 after installation. The size of its first wire-passing hole 831 is adapted to the outer diameter of the flexible connector conductor 9, allowing the flexible connector conductor 9 to pass through smoothly while minimizing the fit gap between the flexible connector conductor 9 and the first wire-passing hole 831. After installation, the flexible connector conductor 9 and the wall of the first wire-passing hole 831 are in close contact, forming a gapless seal. The second sealing plug 84 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 841 is adapted to the outer diameter of the flexible connector conductor 9, allowing the conductor to pass through smoothly while minimizing the fit gap between the flexible connector conductor 9 and the second wire-passing hole 841. After installation, the flexible connector conductor 9 and the wall of the second wire-passing hole 841 are in close contact, forming a gapless seal.

[0071] The first sealing plug 83 and the second sealing plug 84 are made of elastic materials, such as silicone or rubber.

[0072] The waterproof hinge 8 in this embodiment achieves a harmonious balance between structural sealing and functional practicality through the synergistic design of a double-hinge support and double-sealing plugs. Its core benefits 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 conductor 9 forms a double sealing barrier, effectively preventing sweat, rainwater, and ambient moisture from seeping into the frame or temples 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 9. The hinge support structure can be adapted 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 9 during assembly, reduce user maintenance costs, and significantly enhance the market competitiveness of the product.

[0073] In one embodiment, the first perforation 8111 extends from the inside to the outside along the penetrating direction, and the diameter of the first perforation 8111 is tapered. 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.

[0074] The first perforation 8111 is a perforation connecting the first inner cavity of the temple housing 1 with 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 housing 2 with 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.

[0075] The first perforation 8111 serves as a communication channel between the first inner cavity of the temple housing 1 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 8111 is largest at the starting end on the inner cavity side of the temple housing 1, 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 83 is designed synchronously with the contraction shape of the first perforation 8111, and the whole is a conical (or stepped conical) shape that complements the first perforation 8111. During installation, it is inserted from the large diameter end (inner cavity side) of the first perforation 8111 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 8111, thus preventing the first sealing plug 83 from undergoing axial displacement during use.

[0076] Similarly, the second perforation 211 serves as a communication channel between the second inner cavity of the frame housing 2 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 84 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 84 during use.

[0077] In this embodiment, the conical inner cavity formed by the shrinking first perforation 8111 and / or the second perforation 211 provides a wedge-shaped positioning space for the sealing plug. After the elastic first sealing plug 83 and / or the second sealing plug 84 are inserted, 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 9, 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.

[0078] In one embodiment, reference is made to Figure 17 The first sealing plug 83 includes a first insertion part 833 and a first limiting part 832 connected together. The first insertion part 833 is inserted into the first through hole 8111, and the first limiting part 832 abuts against the inner end face of the first connecting seat 811. And / or, the second sealing plug 84 includes a connected second insertion portion 843 and a second limiting portion 842, the second insertion portion 843 being inserted into the second through hole 211, and the second limiting portion 842 abutting against the inner end face of the second connecting seat 821.

[0079] The first sealing plug 83 consists of an integrally formed first insertion part 833 and a first limiting part 832. The shape of the first insertion part 833 is perfectly matched with the inner wall contour of the first through hole 8111, ensuring a tight fit with the hole wall after insertion. The first limiting part 832 is an annular or sheet-like structure with an outer diameter larger than the diameter of the first through hole 8111. When the first insertion part 833 is fully inserted into the first through hole 8111, the first limiting part 832 will tightly abut against the inner end face of the first connecting seat 811 (i.e., the end face facing the first inner cavity of the temple housing 1), forming an axial limit. Similarly, the second insertion part 843 of the second sealing plug 84 is correspondingly inserted into the second through hole 211 of the second connecting seat 821. The outer diameter of the second limiting part 842 is larger than the diameter of the second through hole 211. After assembly, it abuts against the inner end face of the second connecting seat 821 (the end face facing the second inner cavity of the frame housing 2), achieving the same axial positioning effect as the first sealing plug 83.

[0080] 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 9 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.

[0081] In one embodiment, reference is made to Figure 15 The penetrating direction of the first wire hole 831 extends along an arc, and the perpendicular bisectors of the two ends of the first wire hole 831 form an angle with each other.

[0082] In application, the first hinge support 81 is usually connected to the inner corner of the temple housing 1 and the frame housing 2. That is, the first hinge support 81 is located on the side of the temple housing 1 rather than the end face. The first wire hole 831 is set to pass through along an arc, and the perpendicular bisectors of the two ports form an angle with each other. That is, the first wire hole 831 passes through the first sealing plug 83 along an arc, and its overall trajectory is a smooth arc (not a straight line). The perpendicular bisectors of the two ports (inner port and outer port) of the first wire hole 831 have a clear angle. The inner port is the port that connects to the first inner cavity of the temple housing 1, where the perpendicular bisector extends along the length direction of the temple housing 1. The outer port is the port facing the internal space of the hinge, where the perpendicular bisector tends to extend perpendicular to the length direction of the temple housing 1, so that the arc trajectory accurately connects the wiring requirements of the length direction of the temple housing 1 and the perpendicular length direction of the temple housing 1. The arc design is perfectly matched with the side assembly position of the first hinge support 81. Since the first hinge support 81 is connected to the side of the temple housing 1, after the flexible conductor 9 is led out from the inside of the temple housing 1 (arranged along the length direction), it needs to turn to the inside of the hinge (towards the length direction perpendicular to the temple housing 1) to connect to the circuit on the side of the frame housing 2. The trajectory of the arc-shaped wire hole matches this turning path, avoiding excessive bending and damage to the flexible conductor 9.

[0083] In this embodiment, the conductor's smooth turning is achieved through the arc trajectory of the first wire-passing hole 831, 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 9, and precisely guides the direction of the flexible connector conductor 9 to avoid misalignment or breakage inside the hinge, ensuring the stability of circuit signal transmission. On the other hand, the arc design is highly compatible with the side assembly position 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.

[0084] In one embodiment, reference is made to Figure 14 and Figure 17 The first hinge portion 812 and the second hinge portion 822 are configured such that one includes two spaced-apart first hinge bosses 8121 and the other includes one second hinge boss 8221, with the two first hinge bosses 8121 respectively hinged to the two opposite sides of the second hinge boss 8221.

[0085] If the first hinge portion 812 adopts a double-protrusion design, it includes two parallel and spaced-apart first hinge protrusions 8121, with a gap between the two protrusions to accommodate the insertion of a single protrusion. Correspondingly, the second hinge portion 822 is provided with a second hinge protrusion 8221, the thickness of which matches the spacing width between the two first hinge protrusions 8121. During assembly, the second hinge protrusion 8221 is inserted into the gap between the two first hinge protrusions 8121, and the hinge shaft (such as a pin) passes through the first hinge protrusion 8121 and the second hinge protrusion 8221 in sequence to achieve a rotational connection between the two. Conversely, if the second hinge portion 822 is a double-protrusion structure and the first hinge portion 812 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.

[0086] 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 8121 and the second hinge boss 8221 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.

[0087] 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 service life, and ensuring smooth and precise operation when the smart glasses unfold and fold, thus enhancing the user experience. On the other hand, the nesting gap provides dedicated routing space for the flexible conductor 9, reducing the risk of wear on the flexible conductor 9 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 processing costs.

[0088] In one embodiment, a third through hole 81211 is formed between the two first hinge bosses 8121, and a fourth through hole 8221 is provided on the second hinge boss 8221. The first through hole 8111, the third through hole 81211, the fourth through hole 82211 and the second through hole 211 pass through each other to form a connected wire channel.

[0089] The wiring channel is formed by the sequential connection of the first through hole 8111, the third through hole 81211, the fourth through hole 82211, and the second through hole 211. The third through hole 81211 is located between the two first hinge bosses 8121, and its axis is aligned with the axis of the outer port of the first through hole 8111, ensuring that the conductor can smoothly enter after passing through the first through hole 8111. The fourth through hole 82211 is located at the center of the second hinge boss 8221, and its axis is coaxial with the axis of the third through hole 81211, so that the conductor can smoothly transition from the fourth through hole 82211 to the second through hole 211, ultimately forming a continuous wiring path of "inner cavity of temple housing 1 → first through hole 8111 → third through hole 81211 → fourth through hole 82211 → second through hole 211 → inner cavity of frame housing 2".

[0090] In this embodiment, the wiring channel completely encloses the flexible conductor 9 within the hinge's internal structure throughout its entire routing process from the inner cavity of the temple housing 1 to the inner cavity of the frame housing 2. This prevents the conductor from being exposed to the hinge gap or the external environment. Specifically, the flexible conductor 9 is guided and turned by the arc structure within the first wire hole 831. When it enters the third through hole 81211 and passes through the fourth through hole 82211, it is positioned by the second hinge boss 8221. Finally, it enters the inner cavity of the frame housing 2 through the second wire hole 841. The entire routing follows a fixed channel. Even when the hinge rotates, the flexible conductor 9 only moves slightly within the channel and will not deviate, become entangled, or rub against external components. Because the third through hole 81211 and the fourth through hole 82211 rotate synchronously with the hinge (the first hinge boss 8121 rotates while driving the third through hole 81211, and the second hinge boss 8221 rotates while driving the fourth through hole 82211), 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.

[0091] In one embodiment, reference is made to Figure 17 A shielding plate 8122 is connected between the two first hinge bosses 8121, avoiding the second hinge boss 8221. Within the rotation range set by the first hinge support 81 and the second hinge support 82, the shielding plate 8122 always blocks the opening at the end of the fourth through hole 82211.

[0092] The shield 8122 is connected between the two first hinge bosses 8121 and has a sheet-like structure. Its installation position avoids the rotation trajectory of the second hinge boss 8221, so that it does not interfere with the second hinge boss 8221 and can cover the end opening of the fourth through hole 82211 (i.e. the side port of the fourth through hole 82211 facing the external environment). The size and shape of the shield 8122 are customized according to the position of the fourth through hole 82211 and the rotation range of the first and second hinge supports 82, ensuring that the shield 8122 always maintains a corresponding shielding relationship with the end opening of the fourth through hole 82211 within the full rotation range of the smart glasses when they are unfolded (wearing state) and folded (storage state), with no exposed gaps. The edges of the baffle plate 8122 are rounded to prevent scratching the surface of the second hinge boss 8221 when rotating. At the same time, a small buffer space is reserved between the baffle plate 8122 and the second hinge boss 8221 to ensure smooth rotation and reduce the path of dust and liquid entering the fourth perforation 82211 by close-range shielding.

[0093] In this embodiment, the dynamic following blocking function of the shield 8122 enables continuous protection of the fourth perforation 82211 opening within its full rotation range, effectively blocking dust and foreign objects from entering the wiring channel. This prevents conductor damage due to foreign object scratches or channel blockage from affecting signal transmission. At the same time, it significantly reduces the total amount of liquid entering the channel, lowers the waterproof pressure on the sealing plug, and extends the service life of the sealing plug. On the other hand, the shield 8122 has a simple structure, requiring only the addition of a sheet-like component between the two first hinge bosses 8121. 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.
