Description

Technical Field

[0001] This utility model relates to the field of smart wearable device technology, and in particular to a smart glasses. Background Technology

[0002] In current smart glasses development, electronic circuits and sensors need to be integrated inside the frame, typically requiring the design of wiring channels within the frame for routing the circuitry. To ensure the reliability of the internal circuitry in complex operating environments, existing technologies generally use TR or PC materials to integrally mold the frame through injection molding. While this manufacturing method helps improve structural stability, its inherent limitations prevent the frame from achieving the same lightweight, slim structure and the use of diverse electroplating and surface treatment processes to enhance the product's texture and quality as traditional high-end glasses. This results in a tendency for smart glasses frames to have a uniform profile, hindering the creation of diverse, personalized, or ergonomically designed curved surfaces, thus limiting further improvements in the appearance and fit of smart glasses.

[0021] In existing technologies, smart glasses frames mostly adopt a one-piece molding structure to ensure the reliability of internal circuitry, but this process limits the diversity of frame design. Traditional structures struggle to balance complex curved shapes with ergonomic requirements, resulting in highly homogenized product appearances and insufficient wearing comfort. With the growing demand for personalized wearable devices, users expect frames to possess unique aesthetic features while also demanding a neat and protected internal circuit layout, posing a dual challenge to structural design.

[0022] Therefore, please refer to Figure 1 , Figure 2 and Figure 3This application proposes a smart glasses structure comprising an inner lens frame 10 and an outer lens frame 20. The inner lens frame 10 includes two inner lens frames 11 and a central beam 12. The two ends of the central beam 12 are connected to the inner lens frames 11, and a first wiring groove 12a with a through hole 12b is provided inside for arranging the electronic control line 1. The inner lens frame 11 and the center beam 12 are made of metal. The outer frame 20 includes two brow frames 21, each brow frame 21 being fitted onto the upper edge of an inner lens frame 11. One end of each brow frame 21 is detachably connected to the inner lens frame 11, and the other end of each brow frame 21 has a hinge position 21a for mounting the hinge component of the temple. Each brow frame 21 and an inner lens frame 11 enclose a second wiring groove 20a, which is connected to two through holes 12b. The two brow frames 21 are made of plastic. The electrical control line 1 runs sequentially from the hinge position 21a of one brow frame 21, the second wiring groove 20a, the through hole 12b at one end of the center beam 12, the first wiring groove 12a, the through hole 12b at the other end of the center beam 12, the second wiring groove 20a of the other brow frame 21, and the hinge position 21a.

[0023] In this embodiment, the inner frame 10 refers to the basic frame structure that carries optical components and circuitry, and can be injection molded from polycarbonate. The central beam 12 serves as a transverse component connecting the two inner frame lenses 11. Its first wiring groove 12a is formed through an in-mold insert injection molding process to regulate the routing of the electrical control line 1. Through holes 12b are located at both ends of the central beam 12, and chamfering guides the circuitry to smoothly transition to the second wiring groove 20a. The outer frame 20 adopts a detachable design. The brow lens frame 21 engages with the inner frame lenses 11 via a snap-fit ​​structure, forming a closed channel enclosing the circuitry. The cross-sectional shape of the second wiring groove 20a adapts to different wire diameter requirements, and the groove wall is provided with an anti-wear textured layer. Each brow lens frame 21 has a hinge position 21a at its other end, which is used to install the hinge component of the temple; the hinge component described here is a hinge. Specifically, the central beam 12 of the inner frame 10 serves as the wiring hub, with the main body of the electrical control line 1 fixed via a pre-formed first wiring groove 12a. The electrical control line 1 enters the second wiring groove 20a of the left brow frame 21 from the hinge position 21a located on the left side, then enters the first wiring groove 12a of the central beam 12 through the through hole 12b on the left side, exits through the through hole 12b on the right side of the central beam 12, then passes through the second wiring groove 20a of the right brow frame 21, and finally exits from the hinge position 21a of the right brow frame 21, thus forming a complete electrical control wiring method. When the brow frame 21 covers the upper edge of the inner lens frame 11, its inner sidewall and the outer sidewall of the inner lens frame 11 form an annular gap, which constitutes the second wiring groove 20a that encloses the exposed electrical control line 1. The through hole 12b of the center beam 12 is connected to the inner cavity of the brow frame 21, so that the electrical control line 1 is protected throughout the process. During installation, the electrical control line 1 is pre-arranged in the first wiring groove 12a of the center beam 12 of the inner frame 10, and then pasted to the outer wall of the inner lens frame 11 of the inner frame 10, further reducing the installation space of the electrical control line 1. Then the outer frame 20 is assembled to complete the circuit encapsulation.

[0024] Compared to existing technologies, traditional solutions, where the wiring channels and exterior structure are integrally molded, result in the outer frame's shape being limited by wiring requirements. This solution, through a nested structure of the inner frame 10 and the outer frame 20, allows the outer frame 20 to be independently designed with curved surfaces without affecting the wiring layout. The split structure also facilitates the quick replacement of the outer frame 20, meeting users' needs for different appearance styles without altering the internal wiring architecture.

[0025] This application utilizes a metal inner lens frame 11 and a central beam 12 to ensure reliable installation of the electronic control line 1, paired with a plastic outer lens frame 20. The plastic outer lens frame 20 can freely adopt various complex curved shapes, which not only provides smart glasses with a diverse range of styles comparable to traditional glasses, but also significantly enhances the overall texture and quality of the product, offering new possibilities for balancing functionality and aesthetics in smart glasses. The flexible combination of the metal inner lens frame 11, central beam 12, and plastic outer lens frame 20 compensates for the current shortcomings in materials and design of smart glasses.

[0026] Furthermore, the entire electrical control line 1 is contained within the enclosed channel formed by the inner lens frame 10 and the outer lens frame 20, effectively preventing direct impact of external stress on the line. This structure also supports modular assembly, allowing for individual line maintenance by disassembling the outer lens frame 20, significantly improving product maintainability.

[0027] Please see Figures 2 to 4This application further proposes that the central beam 12 of the smart glasses includes a rear central beam shell 121 and a front cover 122. The two ends of the rear central beam shell 121 are respectively connected to two inner lens frames 11. The rear central beam shell 121 is provided with an installation opening 121a and two through holes 12b. The front cover 122 is detachably connected to the installation opening 121a and surrounds the rear central beam shell 121 to form a first wiring groove 12a.

[0028] In this embodiment, the rear center beam shell 121 refers to the supporting component connecting the two inner lens frames 11. Specifically, it can be formed by injection molding and have through holes 12b for constructing the basic wiring channel for the electrical control line 1. The front cover 122 refers to the independent component covering the mounting opening 121a. Specifically, it can be connected by snaps or screws to facilitate inspection and maintenance of the wiring trough. The mounting opening 121a refers to the irregularly shaped through hole provided in the rear center beam shell 121. Specifically, it can be formed by die stamping to create an open operating space for the wiring trough.

[0029] Specifically, the rear center beam shell 121 is injection molded to form a stable connection with the inner lens frame 11, and the through holes 12b at both ends of its top form a continuous wiring path with the edge of the inner lens frame 11. The front cover 122 is fixed to the mounting opening 121a by clips or screws, forming a closed cable tray space together with the rear center beam shell 121. The electrical control line 1 is led out from the through hole 12b and extends along the edge of the inner lens frame 11, forming a protected wiring channel. The detachable structure design allows for easy replacement of wiring or maintenance of circuits by simply removing the front cover 122.

[0030] Through the above technical solution, this application solves the maintenance difficulty caused by the non-removable wiring channels of traditional smart glasses, enabling the maintenance of the electronic control line 1 to be completed without damaging the overall frame structure. The split design ensures the structural integrity of the wiring channel while allowing for independent design of the outer frame 20, avoiding the limitation on appearance freedom caused by wiring maintenance needs.

[0031] Please see Figure 2 and Figure 3 This application further proposes that the rear central beam shell 121 and the two inner lens frames 11 are integrally formed structures.

[0032] In this embodiment, the one-piece molding structure refers to the rear center beam shell 121 and the inner lens frame 11 being formed as a whole through injection molding or metal casting. This one-piece molding structure, by eliminating assembly gaps, can improve the connection strength between the center beam 12 and the lens frame, avoiding the loosening problem caused by vibration in a split structure.

[0033] Specifically, the integrated design of the rear center bridge shell 121 and the inner lens frame 11 creates a continuous, closed wiring channel within the inner lens frame 10. The through-hole 12b of the first wiring groove 12a is precisely aligned with the edge of the inner lens frame 11 during the molding stage, allowing the electrical control line 1 to extend directly along the edge of the inner lens frame 11 to the second wiring groove 20a after passing through the through-hole 12b. When the brow frame 21 covers the outside of the through-hole 12b, the second wiring groove 20a and the first wiring groove 12a form a continuous cable protection channel, while the outer lens frame 20 can still be independently disassembled and replaced.

[0034] Through the above technical solution, this application enables the outer frame 20 to adopt diverse curved shapes while ensuring the reliable fixation of the electronic control line 1. Since the wiring function of the inner frame 10 is realized through an integrated structure, the outer frame 20 does not need to undertake the wiring task, and its material and shape can be independently designed to meet different wearing needs.

[0035] Please see Figures 2 to 4 This application further proposes that the rear center beam shell 121 is provided with a limiting strip 121b at the installation opening 121a, the front cover 122 is limited and abutted against the limiting strip 121b, and is detachably connected to the rear center beam shell 121.

[0036] In this embodiment, the limiting strip 121b refers to a protruding structure extending along the edge of the mounting opening 121a. Specifically, it can be integrally processed with the rear middle beam shell 121 using injection molding process, and is used to limit the assembly position of the front cover 122 and prevent its lateral displacement.

[0037] Specifically, the mounting opening 121a of the rear center beam shell 121 has a limiting strip 121b perpendicular to the shell edge, and the edge of the front cover 122 has a groove matching the shape of the limiting strip 121b. During assembly, the front cover 122 is pushed longitudinally along the limiting strip 121b, and the groove and the limiting strip 121b form a surface contact constraint, keeping the front cover 122 and the rear center beam shell 121 in a parallel alignment state. After positioning is completed, the front cover 122 and the rear center beam shell 121 are fastened with screws to form a closed first wiring groove 12a. This structure can prevent the sealing failure of the front cover 122 due to assembly deviation, and at the same time ensure that the original assembly state can be quickly restored during disassembly and maintenance.

[0038] Compared to existing technologies, traditional one-piece frames cannot allow for independent disassembly of the front cover 122, necessitating the complete disassembly of the frame for maintenance of the wiring channel. This solution, through the combination of the limiting strip 121b and the detachable connection structure, ensures the positioning accuracy of the front cover 122 assembly while enabling modular maintenance, significantly reducing the risk of structural damage caused by maintenance operations.

[0039] Through the above technical solution, this application solves the problem of low efficiency caused by the need for complete disassembly and assembly of traditional smart glasses wiring channels for maintenance. By constraining the assembly trajectory of the front cover 122 with the limiting strip 121b and combining it with the detachable connection structure, the front cover 122 can be accurately positioned and quickly disassembled and assembled, thereby improving the efficiency of wiring channel maintenance and reducing maintenance costs.

[0040] Please see Figures 2 to 4 This application further proposes two through holes 12b located at both ends of the top of the rear middle beam shell 121.

[0041] In this embodiment, the through hole 12b refers to a through hole located at both ends of the top of the rear center beam shell 121 and penetrating the shell. It can be achieved through machining or injection molding, and is used to guide the electrical control line 1 from the first wiring groove 12a outwards to the second wiring groove 20a. The two ends of the top of the rear center beam shell 121 refer to the top ends of the area where the rear center beam shell 121 connects to the inner lens frame 11. This can be achieved by adjusting the mold structure or assembly positioning, and is used to concentrate the electrical control line 1 in the top edge area of ​​the lens frame.

[0042] Specifically, through holes 12b are respectively opened at both ends of the top of the rear center bridge shell 121. The electrical control line 1 passes through the through holes 12b from the first wiring groove 12a and extends along the top edge of the inner lens frame 11 to the second wiring groove 20a. Since the through holes 12b are located at both ends of the top, the wiring path of the electrical control line 1 at the top of the frame is restricted to a narrow area near the edge of the lens, thereby avoiding interference with the curved surface design of the outer frame 20. At the same time, after the brow frame 21 covers the through holes 12b, the second wiring groove 20a and the through holes 12b form a continuous and closed wiring channel, further preventing the electrical control line 1 from shifting or wearing at the frame connection.

[0043] This solution limits the vias 12b to both ends of the top, allowing the control line 1 to be routed close to the top edge of the frame. This not only frees up the structural design freedom of the main frame area but also shortens the exposed length of the control line 1. Through this technical solution, this application can ensure the stability of the control line 1 at the connection between the inner and outer frames 20, while avoiding the problem of restricted outer frame contours due to wiring path interference. This balances the reliability of the internal wiring of the smart glasses with the diverse requirements of external styling.

[0044] Please see Figure 2 and Figure 3 This application further proposes that a first mounting hole is provided on the side of the rear center beam shell 121 away from the through hole 12b, a second mounting hole is provided on the front cover 122, and a third mounting hole is provided on the brow frame 21. The third mounting hole, the second mounting hole and the first mounting hole are arranged coaxially, and screws are screwed into the third mounting hole, the second mounting hole and the first mounting hole in sequence, so that the rear center beam shell 121, the front cover 122 and the brow frame 21 can be detachably connected.

[0045] In this embodiment, the first mounting hole refers to a positioning hole structure located in the area of ​​the rear center beam shell 121 away from the through hole 12b. Specifically, it can be achieved by injection molding a threaded metal insert for threaded engagement with the screw. The second mounting hole refers to a through hole structure in the front cover 122 corresponding to the position of the first mounting hole. Specifically, it can be directly formed using an injection mold for transmitting the tightening force of the screw. The third mounting hole refers to a stepped hole structure at the corresponding position of the browline frame 21. Specifically, it can be formed using a drilling process for accommodating the screw head and providing positioning.

[0046] Specifically, when the brow frame 21 needs to be installed, its third mounting hole is precisely aligned with the second mounting hole of the front cover 122 and the first mounting hole of the rear center beam 121 through coaxial positioning. Screws pass through the third and second mounting holes sequentially and are then screwed into the threaded structure of the first mounting hole, achieving a single-point tightening that simultaneously connects and secures the brow frame 21 to the inner frame 10 assembly. This structure allows the outer frame 20 to be disassembled and installed without damaging the wiring channel, and the brow frame 21 can be removed independently for maintenance without affecting the internal wiring structure.

[0047] This solution integrates the outer frame 20, the front cover 122, and the rear center beam shell 121 into a single screw connection point through the nested design of coaxial mounting holes, which reduces assembly steps and maintains the positioning accuracy between the components.

[0048] Please see Figures 2 to 4 This application further proposes that one end of each eyebrow frame 21 is covered with a through hole 12b so that the through hole 12b is located within the second wiring groove 20a.

[0049] In this embodiment, the brow frame 21 covering the through hole 12b means that the edge of the brow frame 21 extends above the through hole 12b to form a shielding structure. Specifically, this can be achieved by using an injection molding process to extend the end of the brow frame 21 outward to form a covering portion. This covering portion can prevent external foreign objects from entering the first wiring groove 12a through the through hole 12b. The through hole 12b being located within the second wiring groove 20a means that the through hole 12b is enclosed by the second wiring groove 20a formed by the brow frame 21 and the inner lens frame 11. Specifically, this can be achieved by adjusting the coverage area of ​​the brow frame 21 to completely block the opening of the through hole 12b. This structure allows the electrical control wire 1 to pass through the through hole 12b and directly enter the second wiring groove 20a, preventing the wire from being exposed.

[0050] Specifically, when the brow frame 21 is fitted over the inner lens frame 11, its extended end completely covers the through hole 12b on the bridge 12, so that the through hole 12b is enclosed within the second wiring groove 20a between the brow frame 21 and the inner lens frame 11. The electrical control line 1 passes through the hole 12b from the first wiring groove 12a and extends along the second wiring groove 20a to other areas of the frame. The covering structure of the brow frame 21 not only hides the opening of the through hole 12b, but also forms a continuous protective wrap around the electrical control line 1 through the second wiring groove 20a, while not affecting the freedom of the appearance design of the outer frame 20.

[0051] This solution completely encloses the wiring channel within the cavity formed by the inner and outer frames 20 by covering the via 12b with the eyebrow frame 21. This not only improves the concealment of the wiring but also avoids reliability issues caused by exposed openings.

[0052] Please see Figure 2 and Figure 3 This application further proposes that the via 12b is inclined on the side away from the inner lens frame 11 and is parallel to the edge of the inner lens frame 11.

[0053] In this embodiment, the inclined arrangement of the side of the through hole 12b away from the inner lens frame 11 means that the outer edge of the through hole 12b forms a slope. This can be achieved by machining or by pre-reserving an inclined surface during injection molding. This inclined surface is used to guide the electrical control line 1 to smoothly transition from the first wiring groove 12a to the second wiring groove 20a. The parallel arrangement with the edge of the inner lens frame 11 means that the extension direction of the inclined surface of the through hole 12b maintains the same angle as the outer contour of the inner lens frame 11. This can be achieved by adjusting the forming angle of the mold or the assembly positioning structure. This parallel relationship ensures that the electrical control line 1 extends along a predetermined path along the edge of the inner lens frame 11 after passing through the through hole 12b.

[0054] Specifically, the parallel relationship between the inclined sidewall of the through-hole 12b and the edge of the inner lens frame 11 allows the control line 1 to extend smoothly along the natural contour of the inner lens frame 11 to the second wiring groove 20a without forming an acute angle bend when passing through the through-hole 12b. Guided by the inclined surface, the control line 1 closely follows the edge of the inner lens frame 11, avoiding friction or compression with the frame structure. At the same time, the parallel arrangement ensures that the distribution path of the control line 1 in the second wiring groove 20a matches the overall shape of the frame, reducing stress concentration caused by line bending.

[0055] This solution uses a tilted and parallel design to distribute the bending angle of the electrical control line 1 into a smooth transition, significantly reducing the risk of line wear.

[0056] Please see Figure 2 and Figure 4Furthermore, this application proposes that the width at both ends of the middle beam 12 is greater than the width at the middle position of the middle beam 12.

[0057] In this embodiment, the width at both ends of the central beam 12 refers to the lateral dimension of the area where the central beam 12 connects to the inner lens frame 11. This can be achieved by increasing the lateral extension of the connection portion, which enhances the connection strength between the central beam 12 and the inner lens frame 11. The width at the middle of the central beam 12 refers to the lateral dimension of the central area, which can be achieved by reducing the lateral dimension of the central area. This design provides a more optimized spatial layout for the first wiring groove 12a inside the central beam 12.

[0058] Specifically, the increased width at both ends of the center beam 12 disperses stress from both sides of the frame, preventing breakage due to prolonged wear or external pressure. Simultaneously, the reduced width in the middle allows for more space for the electrical control wires 1 within the first wiring channel 12a while maintaining overall rigidity, preventing friction between the electrical control wires 1 and the inner wall of the center beam 12. Through its wider ends and narrower middle, the center beam 12 meets structural strength requirements while also adapting to the curved shape of the outer frame 20, thus supporting diverse aesthetic designs for the outer frame 20.

[0059] In some specific embodiments, the width at both ends of the central beam 12 can be formed by locally thickening the material, for example, by providing trapezoidal or arc-shaped widening portions in the connection area. The width reduction at the middle position can be achieved by a symmetrically recessed arc-shaped profile to maintain the overall streamlined appearance of the central beam 12.

[0060] Compared to existing technologies, current smart glasses typically employ a uniform width design for the center beam to simplify manufacturing, but this results in material redundancy in the central area of ​​the center beam and limited wiring space. This solution differentiates the width distribution of the center beam 12, ensuring structural reliability while providing dual optimization space for the layout of the electronic control line 1 and the external frame design.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
