Description

Technical Field

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

[0002] In the field of smart glasses technology, existing smart glasses frames are typically assembled by gluing the front and back frames together. Currently, the assembly method for smart glasses frames on the market involves dividing the frame into two main body parts at the 1 / 3 mark (front frame, frame, and nose pad), then installing wiring (circuit boards) and electronics (LED lights, cameras) inside the frame, and finally bonding them together with adhesive.

[0003] However, this type of adhesive structure has certain drawbacks, mainly manifested in the large adhesive area, which makes it prone to cracking and deformation after long-term wear and bending stress, affecting the overall quality and lifespan of smart glasses, and making it difficult to meet users' needs for the reliability and durability of smart glasses frames. Utility Model Content

[0004] The main purpose of this invention is to propose a smart glasses that aims to reduce the open area while improving the overall robustness of the smart glasses frame, enhancing the convenience and reliability of the internal wiring (circuit) and electronic installation, and preventing deformation and cracking of the frame in the later stages.

[0005] To achieve the above objectives, the present invention proposes smart glasses, which include:

[0006] A picture frame, the picture frame having an inner cavity, and a mounting groove communicating with the inner cavity being formed at the top of the picture frame; and

[0007] The top cover is adhered to the groove opening of the mounting slot.

[0008] In one embodiment, the frame is further provided with a recessed groove, which is located at the edge of the groove opening of the mounting groove and surrounds the groove opening of the mounting groove; the top cover abuts against the recessed groove.

[0009] In one embodiment, the mounting groove includes a main groove and two limiting grooves, the two limiting grooves being located at both ends of the main groove, and the recessed groove being provided along the groove edges of the main groove and the limiting grooves;

[0010] The top cover includes a main cover and two limiting blocks. The two limiting blocks are connected to both ends of the main cover. The main cover is closed at the main groove. Each limiting block is detachably connected to one of the limiting grooves.

[0011] In one embodiment, the limiting block includes an upper limiting piece and a lower locking portion, the lower locking portion protruding from the bottom of the upper limiting piece;

[0012] The upper limit plate is detachably connected to the recess, and the lower locking part is inserted into the limiting groove.

[0013] In one embodiment, the edge of the lower latching portion is rounded.

[0014] In one embodiment, an LED light is installed in the inner cavity corresponding to the position of one of the limiting grooves.

[0015] In one embodiment, a camera is installed in the inner cavity at a position corresponding to the other limiting groove.

[0016] In one embodiment, the smart glasses further include two temples, one end of each temple is hinged to one end of the frame, and each temple is provided with a sound cavity communicating with the inner cavity. One of the sound cavities is equipped with a PCB board, a battery, a sensor and a teardrop-shaped speaker. The battery, the sensor and the speaker are electrically connected to the PCB board.

[0017] In one embodiment, each temple is further provided with a front sound hole and a rear sound hole, the front sound hole being located on the top outer wall of the temple and the rear sound hole being located on the bottom outer wall of the temple.

[0018] The smart glasses of this invention include a frame and a top cover. The frame has an inner cavity, and a mounting groove communicating with the inner cavity is formed at the top of the frame. The top cover is adhered to the opening of the mounting groove.

[0031] This utility model proposes a smart glasses.

[0032] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment of the present invention, the smart glasses include a frame 10 and a top cover 20. The frame 10 has an inner cavity 10a, and a mounting groove 10b communicating with the inner cavity 10a is formed on the top of the frame 10. The top cover 20 is adhered to the groove opening of the mounting groove 10b.

[0033] The inner cavity 10a refers to the sealed space formed inside the frame 10, which can be formed by injection molding. The mounting groove 10b refers to the opening structure that penetrates the top surface of the frame 10, which can be formed by injection molding or CNC machining, and its size design must ensure that it can accommodate the predetermined functional modules. The top cover 20 is bonded to the groove opening of the mounting groove 10b, which can be achieved by adhesive bonding or ultrasonic hot melt bonding, and the connection stability is maintained by physical limiting.

[0034] Specifically, the frame 10 integrates electronic components through the internal cavity 10a structure, and the opening design of the mounting slot 10b facilitates the assembly of functional modules. The mating surface between the top cover 20 and the mounting slot 10b is equipped with a positioning structure, forming a continuous and complete outer surface of the frame 10 when closed. This split structure decomposes the traditional integral frame 10 into two independent parts, reducing the assembly contact area during assembly to the necessary area.

[0035] Therefore, this invention creates a mounting groove 10b at the top of the frame 10, allowing the top cover 20 to directly fit over the mounting groove 10b. Even if the top cover 20 detaches from the mounting groove 10b during use, the frame 10 will not deform or crack. This design minimizes the open area for the components inside the frame 10, while also improving the overall robustness of the smart glasses frame. It also enhances the convenience and reliability of the internal wiring (circuit) and electronic installation, preventing deformation and cracking of the frame later on. This design achieves non-destructive re-assembly and disassembly, ensuring the integrity and robustness of the frame 10's appearance.

[0036] Please see Figure 1 , Figure 2 and Figure 5 This application further proposes that the frame 10 is provided with a recessed groove 10c, the recessed groove 10c is located at the edge of the groove of the mounting groove 10b, and the recessed groove 10c is arranged around the groove of the mounting groove 10b, and the upper cover 20 abuts against the recessed groove 10c.

[0037] In this embodiment, the recess 10c refers to an annular groove formed by a downward indentation at the edge of the opening of the mounting groove 10b. The surrounding arrangement means that the recess 10c forms a continuous, closed annular structure along the edge of the opening of the mounting groove 10b. Specifically, it can be integrally molded using a mold, ensuring that the extension path of the recess 10c completely coincides with the contour of the opening of the mounting groove 10b. The abutment between the upper cover 20 and the recess 10c means that the edge of the upper cover 20 is embedded in the recess 10c and forms surface contact with the groove wall. Specifically, the shape of the edge of the upper cover 20 can be matched with the cross-section of the recess 10c through machining.

[0038] Specifically, when the top cover 20 is installed onto the frame 10, the annular groove structure of the recess 10c provides a positioning reference for the top cover 20, with the edge of the top cover 20 completely embedded inside the recess 10c. The continuous closing feature of the recess 10c increases the contact area between the top cover 20 and the frame 10 to an annular surface contact state, which is about 3-5 times larger than the traditional point contact method. The matching design of the depth and width of the recess 10c forms a mechanical limiting structure, restricting the displacement of the top cover 20 in the vertical direction, and the annular distribution feature ensures that the force is evenly transmitted along the circumference, avoiding local stress exceeding the material yield strength.

[0039] This application effectively solves the problem of structural fracture caused by unstable connection between the frame 10 and the top cover 20. The annular structure of the recess 10c ensures uniform distribution of contact stress, avoiding localized stress concentration that could lead to plastic deformation. Compared to adhesive bonding, the mechanical engagement method improves connection reliability, preventing structural separation due to adhesive failure during long-term use. The precise fit between the top cover 20 and the recess 10c ensures consistent assembly accuracy and reduces the need for manual adjustments during production.

[0040] This application further proposes that the mounting groove 10b includes a main groove 101b and two limiting grooves 102b, the two limiting grooves 102b are located at both ends of the main groove 101b, and the sink 10c is provided along the groove edges of the main groove 101b and the limiting grooves 102b; the upper cover 20 includes a main cover 21 and two limiting blocks 22, the two limiting blocks 22 are connected to both ends of the main cover 21, the main cover 21 covers the main groove 101b, and each limiting block 22 is detachably connected to a limiting groove 102b.

[0041] The main groove 101b is a linear groove structure used to accommodate the core electronic components of the smart glasses. It can be manufactured using injection molding, and its width matches the dimensions of the main cover 21 for stable coverage. The limiting groove 102b is a rectangular groove structure located at both ends of the main groove 101b. It can be formed by milling, and its depth matches the thickness of the limiting block 22 for precise positioning. The limiting block 22 is a protruding structure with a shape complementary to the limiting groove 102b. It can be injection molded from elastic plastic material, and its sidewall contacts the inner wall of the limiting groove 102b to restrict lateral displacement. The recessed groove 10c is a stepped recess surrounding the edge of the mounting groove 10b. It can be processed using stamping, and its depth matches the edge thickness of the upper cover 20 for seamless connection.

[0042] Specifically, the main groove 101b and the main cover 21 cooperate to cover the core component area, and the limiting groove 102b and the limiting block 22 form a physical locking structure. When the main cover 21 is fastened to the main groove 101b, the two limiting blocks 22 are respectively embedded in the corresponding limiting grooves 102b, and the side wall of the limiting block 22 forms a surface contact constraint with the inner wall of the limiting groove 102b. The recessed groove 10c extends continuously along the edge of the main groove 101b and the limiting groove 102b, so that the entire edge of the upper cover 20 is embedded in the recessed groove 10c. The distribution pattern of the main groove 101b and the limiting groove 102b forms a three-point positioning structure. Through the covering effect of the middle of the main groove 101b and the locking effect of the limiting grooves 102b on both sides, the distributed fixed connection between the upper cover 20 and the frame 10 is realized.

[0043] Compared to existing technologies, traditional smart glasses use a full-surface adhesive bonding method to fix the top cover 20, which carries the risk of structural loosening due to adhesive aging. This solution, however, uses a multi-point mechanical interlocking structure formed by the main groove 101b and the limiting groove 102b, distributing the stress from a single adhesive surface to three independent connection points, effectively avoiding stress concentration. The design of the limiting block 22 embedded in the limiting groove 102b replaces the traditional full-adhesion method, retaining the convenience of disassembly and maintenance while improving connection reliability through physical constraints.

[0044] Please see Figure 1 , Figure 2 and Figure 5This application further proposes that the limiting block 22 includes an upper limiting piece 221 and a lower locking part 222, the lower locking part 222 protruding from the bottom of the upper limiting piece 221; the upper limiting piece 221 is detachably connected to the recess 10c, and the lower locking part 222 is inserted into the limiting groove 102b.

[0045] In this embodiment, the upper limit plate 221 refers to a planar structure that forms a detachable connection with the recess 10c, used to achieve horizontal limiting constraint. The lower locking part 222 refers to a protruding structure extending vertically from the bottom of the upper limit plate 221, which can be implemented using a plug-in component with an undercut or wedge-shaped cross section, used to insert into the limiting groove 102b to form vertical positioning. The recess 10c refers to a recessed structure set around the opening of the mounting groove 10b, which can be implemented using an annular groove or a segmented groove, used to support the upper limit plate 221 and provide a lateral support surface. The limiting groove 102b refers to an independent groove located at both ends of the main groove 101b, which can be implemented using a rectangular or trapezoidal cross section groove, used to accommodate the lower locking part 222 and limit its displacement.

[0046] Specifically, the detachable connection between the upper limit plate 221 and the recess 10c forms a lateral positioning through the mechanical engagement of the contact surfaces, preventing horizontal movement. After the lower locking part 222 is inserted into the limiting groove 102b, its sidewall contacts the groove wall to form a longitudinal constraint, preventing vertical displacement. When subjected to external force, the horizontal force is dispersed through the contact surface between the recess 10c and the upper limit plate 221, while the vertical load is transmitted to the frame 10 body through the insertion structure of the lower locking part 222 and the limiting groove 102b. During disassembly and assembly, the limiting block 22 can be removed entirely by disconnecting the upper limit plate 221 from the recess 10c, without damaging the structural integrity of the insertion part.

[0047] This design provides large-area support through the planar contact between the recessed groove 10c and the upper limit plate 221, while the insertion and engagement of the lower snap-fit ​​part 222 with the limiting groove 102b forms a three-dimensional constraint. This dual limiting mechanism significantly improves connection reliability. In existing technologies, split structures often employ a single plug-in or snap-fit ​​method. This design's layered limiting mechanism maintains ease of assembly and disassembly while enhancing torsional resistance through the synergistic effect of the upper and lower structures.

[0048] Please see Figure 1 , Figure 2 and Figure 5 This application further proposes that the edge of the lower latching portion 222 is rounded.

[0049] In this embodiment, the arc setting refers to processing the edge of the lower latching portion 222 that contacts the limiting groove 102b into an arc-shaped surface. Specifically, it can be formed by stamping or injection molding to create a continuous and smooth transition at the edge. This design reduces the rigid contact area with the inner wall of the limiting groove 102b by eliminating sharp corners, thereby reducing frictional resistance during insertion.

[0050] Specifically, when the lower locking part 222 is inserted into the limiting groove 102b, a sliding contact surface is formed between the arc edge and the groove wall, preventing sharp edges from scratching the internal structure of the frame 10. The guiding effect of the arc surface allows the locking part to automatically adjust the alignment angle during assembly, completing the insertion without precise alignment. In addition, the arc shape disperses contact stress, preventing local stress concentration that could lead to component deformation or wear.

[0051] Compared to existing technologies, traditional snap-fit ​​structures often use right-angled or sharp-angled edges, which can lead to assembly difficulties due to high frictional resistance during repeated disassembly and reassembly. Furthermore, sharp edges may scratch the frame 10 or the snap-fit ​​itself. This solution utilizes the physical properties of rounded edges to transform sliding friction into rolling friction, significantly reducing insertion and extraction forces while avoiding damage to the component surface.

[0052] Through the above technical solution, this application achieves smooth insertion and removal between the snap-fit ​​part and the limiting groove 102b, solving the problems of high assembly resistance and component damage caused by sharp edges. The guiding effect of the rounded edge simplifies the precision requirements of manual operation, improves assembly efficiency, and extends the durability of the snap-fit ​​structure.

[0053] Please see Figure 2 and Figure 3 An LED light 40 is installed in the inner cavity 10a at the position corresponding to one of the limiting grooves 102b.

[0054] In this embodiment, an LED light 40 is installed in the inner cavity 10a of the frame 10, corresponding to the left-side limiting groove 102b; the LED light 40 serves as a signal indicator. Specifically, the LED light 40 can use different flashing frequencies or colors to indicate the working status of the smart glasses, such as low battery, Bluetooth connection status, and incoming call reminders. This design not only makes full use of the space in the limiting groove 102b, avoiding additional occupation of the limited open area inside the frame 10, but also improves the functionality and user experience of the smart glasses.

[0055] Please see Figure 2 and Figure 3 A camera 50 is installed in the inner cavity 10a at the position corresponding to another limiting groove 102b.

[0056] In this embodiment, the camera 50 is one of the core functional components of the smart glasses, used to capture images or videos. It typically consists of a lens, an image sensor (such as CMOS or CCD), and related circuitry, capable of converting optical signals into digital signals to enable functions such as taking photos, recording videos, or making video calls. The limiting groove 102b is a structure on the frame 10 used to fix the temple 30. Its internal space is optimized to not only accommodate the limiting block 22 of the top cover 20 for a stable connection, but also reserve sufficient space for installing other functional components, such as the LED light 40 and the camera 50.

[0057] The camera 50 is installed in the inner cavity 10a of the frame 10, corresponding to the right-side limiting groove 102b. This makes full use of the space in the connection area between the frame 10 and the temple 30, avoiding additional openings or occupying other space on the front or side of the frame 10. This design makes the overall appearance of the smart glasses simpler and more aesthetically pleasing, while reducing the open area.

[0058] Please see Figure 1 , Figure 3 and Figure 4 This application further proposes that the smart glasses also include two temples 30, one end of each temple 30 is hinged to one end of the frame 10, and each temple 30 is provided with a sound cavity communicating with the inner cavity 10a. One of the sound cavities is equipped with a PCB board, a battery, a sensor and a teardrop-shaped speaker. The battery, sensor and speaker are electrically connected to the PCB board respectively.

[0059] In this embodiment, the temple 30 refers to the support component connected to the frame 10. It can be made of lightweight metal or polymer material, and its hollow internal structure accommodates electronic components, including a PCB board, battery, sensor, and teardrop-shaped speaker. The battery, sensor, and speaker are electrically connected to the PCB board. The PCB board controls the speaker to play sound. The sensor detects whether the temple is close to the frame 10 to determine if the glasses are being worn, automatically waking up / putting into sleep mode to save power. The battery powers the PCB board, while the sensor and speaker receive power through the PCB board and perform corresponding tasks. The temple 30 is connected to the inner cavity 10a via a sound cavity, allowing the PCB board's wires to be electrically connected to the electronic components within the inner cavity 10a, enabling the PCB board to control these components. The hinged design allows the temple 30 to open and close, preventing structural breakage due to external impact. Among them, the hinge refers to the movable connection between the temple 30 and the frame 10. Specifically, it can be achieved by using a miniature rotating shaft or an elastic hinge. By controlling the range of rotation angle, the opening and closing stability of the temple 30 is ensured, while reducing stress concentration at the connection.

[0060] The teardrop-shaped horn refers to the geometric outline of the acoustic component. Specifically, it can adopt a curved shape with a sharp front end and a rounded rear end. The sharp end is used to guide the directional propagation of high-frequency sound waves, while the rounded end is used to expand the diffusion range of low-frequency sound waves, thereby achieving a balance between sound field coverage and directivity.

[0061] Specifically, the temples 30 are connected to the frame 10 via a hinge structure, giving them controllable rotational freedom. This allows them to buffer impact energy when subjected to external forces, preventing rigid breakage caused by a fixed connection. When a teardrop-shaped speaker is installed inside the temples 30, its sharp front end faces the ear area, enhancing the penetration of high-frequency sound waves by compressing the sound wave conduction path. The rounded rear end guides the diffusion of low-frequency sound waves through curved surface reflection, thereby optimizing sound transmission efficiency within a limited space.

[0062] Compared with existing technologies, traditional smart glasses temples use a fixed connection method, which is prone to breakage due to external impact. The hinged structure disperses stress through movable connection, which significantly improves structural reliability. Existing speakers mostly use cylindrical or square designs, which can easily cause interference or attenuation of sound waves in narrow spaces. The teardrop-shaped speaker solves the problems of insufficient high-frequency response and narrow sound field coverage by using differentiated sound wave transmission paths.

[0063] Through the above technical solution, this application achieves reliable assembly of the temple 30 and the frame 10, avoiding the risk of breakage caused by external impact. At the same time, the teardrop-shaped speaker optimizes the sound wave conduction characteristics, enhances the directivity of high-frequency sound waves and expands the coverage of low-frequency sound fields, thereby improving the audio transmission quality.

[0064] Please see Figure 1 , Figure 3 and Figure 4 This application further proposes that each temple 30 is also provided with a front sound hole 30b and a rear sound hole 30c, the front sound hole 30b being located on the top outer wall of the temple 30 and the rear sound hole 30c being located on the bottom outer wall of the temple 30.

[0065] In this embodiment, the front sound hole 30b is located on the top outer wall of the temple 30 and is part of the smart glasses' audio system. It is primarily used for sound output, especially when the user is wearing the glasses, as sound can be directly transmitted into the user's ear canal through the front sound hole, providing a clear audio experience. The positional design of the front sound hole 30b effectively avoids sound scattering and interference during propagation, ensuring efficient audio signal transmission. The rear sound hole 30c is located on the bottom outer wall of the temple 30 and works in conjunction with the front sound hole 30b. The rear sound hole 30c mainly provides sound reflection and diffusion, enhancing the stereo and directional quality of the sound through its synergy with the front sound hole 30b. Furthermore, the rear sound hole 30c can also be used to collect ambient sound, enabling the smart glasses to have noise reduction or ambient sound enhancement functions.

[0066] The combined design of the front sound port 30b and the rear sound port 30c provides a more realistic stereo effect. The front sound port 30b directly transmits sound into the user's ear canal, while the rear sound port 30c, through reflection and diffusion, creates a surround sound effect around the user's ears. This design significantly enhances the user's audio experience, especially when watching videos or making voice calls.

[0067] The front sound hole 30b and rear sound hole 30c are integrated into the outer wall of the temple 30, making full use of the space in the temple 30 and avoiding the need for additional openings or installation of audio components in the frame 10 or lens area. This integrated design not only reduces the overall open area of ​​the smart glasses but also maintains a simple and aesthetically pleasing appearance.

[0068] 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. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
