[0002] With the rapid development of technologies such as Augmented Reality (AR), Mixed Reality (MR), and Extended Reality (XR), smart glasses have become portable devices integrating information display, environmental interaction, and video calls. As a core component for interaction, the design and layout of the camera module directly impacts user experience and the device's aesthetics. Currently, most smart glasses fix the camera module to the frame, leaving it constantly exposed. This exposed camera detracts from the overall aesthetic design of the glasses, making them appear overly futuristic and unsuitable for everyday wear, especially in social situations where it can raise privacy concerns. Furthermore, the constantly exposed camera lens is prone to accumulating dust and fingerprints, affecting image quality and requiring frequent cleaning. Utility Model Content

[0021] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] The smart glasses provided in this application embodiment are, for example, augmented reality (AR) glasses, AI glasses, or functional glasses. In other embodiments, the smart glasses may also be virtual reality (VR) glasses or other head-mounted display devices with a glasses-like appearance.

[0023] Please see Figures 1 to 4 One embodiment of this application provides a smart glasses system, which includes a frame 10 and a camera module. The frame 10 has an accommodating space (not shown), and the camera module is movably disposed within the accommodating space.

[0024] The camera module includes a camera 21 and a drive mechanism 22. The drive mechanism 22 drives the camera 21 to move relative to the frame 10, enabling the camera 21 to move to a first position and a second position relative to the frame 10. That is, the camera 21 can move from the first position to the second position, or from the second position to the first position. When the camera 21 is in the first position, the camera 21 is housed within the receiving space; when the camera 21 is in the second position, the camera 21 extends out of the receiving space and is exposed outside the frame 10.

[0025] Based on the above solution, this embodiment of the application hides the camera module inside the frame 10 and exposes it in the frame 10 when in use, thus achieving a balance between the function and aesthetics of smart glasses. When not in use, the camera 21 of the camera module is blocked by the module shell and the frame 10, making it less prone to dust accumulation and reducing the impact on the imaging quality of the camera 21.

[0026] like Figure 3 As shown, in some embodiments, the frame 10 includes a first frame 101 and a second frame 102, with the first frame 101 and the second frame 102 fixedly assembled to form an accommodating space.

[0027] As an example, the first frame 101 is generally plate-shaped, and the second frame 102 is generally cover-shaped. The outer contour shape of the first frame 101 matches the opening shape of the second frame 102. The first frame 101 is fitted into the opening of the second frame 102 and is fixedly assembled with the second frame 102 to form the aforementioned accommodating space. Exemplarily, the first frame 101 is connected to the second frame 102 by means of screws, snap-fit ​​connections, or the like.

[0028] The camera module is assembled into the receiving space along a mounting direction perpendicular to the first frame 101 and the second frame 102. The top of the second frame 102 has an extension hole for the camera 21 to extend out of the receiving space.

[0029] It should be noted that the first frame 101 and the second frame 102 are installed in the front-back direction of the frame 10 when the smart glasses are being worn. Specifically, the first frame 101 is the front frame of the frame 10 module (i.e., the side away from the face), and the second frame 102 is the rear frame of the frame 10 module (i.e., the side closer to the face).

[0030] The first frame 101 and the second frame 102 are made of lightweight materials such as magnesium-aluminum alloy, titanium alloy, and aluminum alloy. They are not only lightweight, but also have high strength and toughness. They will not feel pressured even after wearing for a long time, and are not easy to break or be damaged.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the eyeglass frame 10 is divided into a first eyeglass frame portion 103, a second eyeglass frame portion 105, and a bridge portion 104. The bridge portion 104 is located between the first eyeglass frame portion 103 and the second eyeglass frame portion 105, and the first eyeglass frame portion 103 and the second eyeglass frame portion 105 are integrally formed on the bridge portion 104.

[0032] The camera module is assembled into the receiving space of the nose bridge portion 104 along a mounting direction perpendicular to the first frame 101 and the second frame 102. The top of the nose bridge portion 104 has the aforementioned extension hole, allowing the camera 21 to extend out of the receiving space.

[0033] Since the bridge of the nose 104 is usually located in the middle of the user's face when wearing the device, placing the camera module here can optimize the field of view, making the captured image more consistent with the user's line of sight, and providing a more natural augmented reality experience.

[0034] Continue as Figure 3As shown, in some embodiments, the smart glasses include an optical engine 30. The optical engine 30 is mounted within the receiving space of a first frame portion 103 or a second frame portion 105. The first frame portion 103 and the second frame portion 105 respectively form lens 13 mounting positions for mounting lenses 13, at least one of the two lenses 13 being a waveguide lens 13. The waveguide lens 13 is mounted in the lens 13 mounting position adjacent to the optical engine 30, and the optical engine 30 is used to emit a light beam to the corresponding waveguide lens 13.

[0035] In another embodiment, the number of optical engines 30 is equal to the number of waveguide lenses 13, with one optical engine 30 corresponding to one waveguide lens 13. Specifically, both lenses 13 can also be waveguide lenses 13, and the smart glasses include two optical engines 30. The two optical engines 30 are respectively mounted in the receiving spaces of the first frame portion 103 and the second frame portion 105, and each optical engine 30 is used to emit a beam of light to the corresponding waveguide lens 13.

[0036] like Figure 3 As shown, in some embodiments, the smart glasses include a support frame 40. The support frame 40 is detachably connected to the first frame 101, and the support frame 40 has a first mounting groove 401 on the side facing the second frame 102. The opening of the first mounting groove 401 communicates with an extension hole, and at least part of the camera module is movably disposed in the first mounting groove 401.

[0037] For example, the support frame 40 is assembled to the first frame 101 or the second frame 102 by means of screw connection, snap-fit ​​connection, etc., thereby fixing it in the receiving space of the bridge portion 104. The surface of the second frame 102 where the bridge portion 104 is located, facing the first frame 101, is provided with a first mounting groove 401. The first mounting groove 401 faces the camera module, and the camera module is movably disposed in the first mounting groove 401.

[0038] In some embodiments, the camera module includes, in addition to the camera 21 and the drive mechanism 22, a camera bracket and a camera FPC assembly. The camera bracket is connected to both the camera 21 and the camera FPC assembly, and the camera 21 is electrically connected to the camera FPC assembly.

[0039] For example, the camera 21 is fixedly mounted on the camera bracket, and the light-incident surface of the camera 21 forms an angle with the moving direction of the camera module.

[0040] The camera FPC assembly can be a flexible circuit board. The flexible circuit board is used to transmit the image signals captured by the camera 21 to the main control board 2 of the smart glasses.

[0041] The second frame 102 has a second mounting groove 1021 on its surface facing the first frame 101. One opening of the second mounting groove 1021 faces upward, and the other opening faces the first frame 101. At least a portion of the camera bracket is movably disposed within the second mounting groove 1021. The second mounting groove 1021 and the first mounting groove 401 together can limit the camera bracket, preventing it from becoming loose, thereby enhancing the installation stability of the camera module within the accommodating space.

[0042] Continue as Figure 3 As shown, in some embodiments, the camera module includes a lifting transmission assembly 23. The drive mechanism 22 drives the camera module to perform linear motion via the lifting transmission assembly 23.

[0043] For example, the drive mechanism 22 is a miniature drive motor, which is fixedly mounted at the bottom of the second mounting slot 1021. The lifting transmission assembly 23 includes a lead screw 231 and a sliding plate 232. The lead screw 231 is connected to the output shaft of the miniature drive motor, and the camera bracket is fixedly mounted on the sliding plate 232. The sliding plate 232 has a threaded hole in the vertical direction, and the sliding plate 232 is sleeved on the lead screw 231 and threadedly connected to the lead screw 231.

[0044] When the camera module's function needs to be activated, the main control board 2 sends a control signal to activate the micro drive motor, driving the lead screw 231 to rotate around its axis. Driven by the lead screw 231, the slide plate 232 moves smoothly vertically, causing the camera module fixed to the slide plate 232 to extend out of the slots and protrusion holes of the first mounting slot 401 and the second mounting slot 1021. Once it reaches the preset height, it is as follows... Figure 2 In the second position shown, the miniature drive motor stops rotating, the camera 21 is exposed outside the frame 10, and the camera 21 enters the working state.

[0045] After camera 21 finishes its working state, the micro drive motor reverses, causing the camera module on the slide plate 232 to be housed in the second mounting slot 1021. Figure 1 In the first position shown, the camera module is hidden inside the frame 10.

[0046] In some embodiments, the lifting transmission assembly 23 includes a guide rod (not shown). The guide rod is fixed within the receiving space and slides in engagement with the slide plate 232.

[0047] For example, the guide rod extends from the bottom of the second mounting groove 1021 toward the opening of the second mounting groove 1021, and the slide plate 232 has a guide hole corresponding to the position of the guide rod. The guide rod is inserted into the guide hole and slides in cooperation with the camera bracket.

[0048] When the drive mechanism 22 drives the slide plate 232 to move relative to the frame 10, the guide rod and guide hole cooperate to guide the slide plate 232 and the camera bracket. Since the fit clearance between the guide rod and the guide hole is precisely calculated, it ensures smooth movement and avoids positional deviation caused by large clearance, ensuring that the camera 21 remains stable during the lifting and lowering process and is not easy to shake or deflect.

[0049] In some embodiments, an angle is formed between the light-incident surface of the camera 21 and the direction of movement of the camera 21, and this angle is between 75° and 105°. For example, α is specifically within the range of 75°, 80°, 85°, 90°, 95°, 100°, 105°, or any two of these values. This expands the field of view of the camera 21 and improves the situation where the camera module is fixed to the slide plate 232 and has a limited field of view.

[0050] For example, the camera module is fixedly mounted on the slide plate 232 via a micro-damping hinge (not shown), so that the light-incident surface of the camera 21 is kept in a predetermined position within the aforementioned angle range, allowing users to manually fine-tune the shooting angle and increasing the fun of the smart glasses.

[0051] Of course, the drive mechanism 22 is not limited to the aforementioned micro drive motor. For example, in some other embodiments, the drive mechanism 22 is manually driven to reduce the energy consumption of the smart glasses.

[0052] Specifically, the lifting transmission assembly 23 adopts a simpler mechanical structure, including a spring, a limit block, and a ball plunger. The camera module is connected to the spring via a bracket. In the non-use state, the spring is compressed, and the camera module is locked within the accommodating space. When the camera module needs to be used, the user releases the lock using a button or other trigger release mechanism. The spring releases, pushing the camera module up to the second position. The ball plunger locks the camera module in the second position. After use, the user gently presses the camera module to overcome the resistance of the ball plunger, pushing it back to the first position and locking it.

[0053] Alternatively, the drive mechanism 22 includes a permanent magnet (not shown) and a drive coil (not shown). The permanent magnet is fixedly mounted on the camera module, and the drive coil is fixedly mounted within the accommodating space and corresponds to the permanent magnet.

[0054] For example, the permanent magnet is connected to the camera bracket by means of bonding, snap-fit ​​connection or other methods, and the drive coil is assembled and fixed to the surface of the second frame 102 facing the first frame 101 by the mounting components.

[0055] When the drive coil is energized, the direction and magnitude of the current in the drive coil are controlled to generate a precise electromagnetic force that acts on the permanent magnet, causing the permanent magnet to drive the camera module to move linearly relative to the frame 10 without contact. Since there are no mechanical parts in physical contact between the camera module and the frame 10, they are less prone to wear and tear, which helps to extend the service life of the smart glasses.

[0056] Please combine Figure 1 and Figure 2 See also Figure 3 In some embodiments, the smart glasses include temples 11 and a control circuit board 60. The temples 11 are connected to opposite ends of the frame 10. The control circuit board 60 is disposed within the temples 11 and electrically connected to a micro-drive motor. The control circuit board 60 has a control module 61 and a sensor assembly 62. The control module 61 is communicatively connected to the main control board 2 of the smart glasses. The sensor assembly 62 includes at least one of a gyroscope, an accelerometer, and a distance sensor, used to detect the user's status and usage scenario.

[0057] Specifically, when the main control board 2 of the smart glasses detects that the user has started a video call or AR application, the micro drive motor drives the camera module to rise automatically. When the camera module is raised for more than a preset time or the user manually closes the video call or AR application, the micro drive motor drives the camera 21 to fall, further enhancing the privacy protection and energy efficiency optimization of the smart glasses.

[0058] In some embodiments, the number of camera modules, the number of micro-drive motors, and the number of lifting transmission components 23 are all multiple. Multiple camera modules are spaced apart along the direction from one temple 11 to another. A micro-drive motor drives a camera module to move linearly via a lifting transmission component 23. Each micro-drive motor is electrically connected to a control circuit board 60. This configuration allows different combinations of cameras 21 to be raised according to different usage scenarios. For example, during video calls, the camera module located on the bridge of the nose 104 is raised; during AR scene interaction, the camera modules on the first frame 103 and / or the second frame 105 are raised. The multi-camera module solution provides richer functionality, and the ingenious layout design makes multiple camera modules invisible in a hidden state, raising only the appropriate camera module when needed.

[0059] To facilitate understanding, we will now use smart glasses as an example to explain their hardware specifications and workflow.

[0060] Hardware specifications: The frame is made of magnesium-aluminum alloy, which is lightweight and strong.

[0061] The nose bridge of the glasses frame has a recessed space measuring (6mm-9mm) × (6mm-9mm) × (4mm-6mm) to accommodate a hidden camera module.

[0062] The drive mechanism uses a miniature DC motor with a diameter of 3mm-5mm.

[0063] The lifting transmission assembly uses a precision lead screw (diameter (1.2mm-1.8mm), pitch (0.3mm-0.38mm)), and the slide plate is made of stainless steel with a thickness of 0.4mm-0.75mm, and has threaded holes that match the lead screw.

[0064] The camera module is a custom-designed 2-megapixel to 16-megapixel autofocus camera, measuring only (3mm-5mm) × (3mm-5mm) × (3mm-4mm). The camera module is fixedly mounted on the slide plate via a micro-damped hinge, allowing for ±15° angle adjustment, enabling users to optimize the shooting angle according to the usage scenario.

[0065] The control circuit board is integrated inside one of the temples. The control module uses a low-power processor to process sensor data and drive the mechanism. Power is supplied by a lithium polymer battery within the temple, achieving long battery life through sophisticated power management.

[0066] The workflow is as follows: 1. The user activates the AR function or video call application; 2. The sensor assembly detects the user's intention and sends a signal to the control module on the control circuit board; 3. The control module on the control circuit board activates the micro drive motor, which rotates forward to drive the threaded rod to rotate; 4. The slide plate rises smoothly under the drive of the screw and the constraint of the guide rod, raising the camera module from the first position to the second position in a short time; 5. Once the camera reaches the second position, the miniature drive motor automatically stops, and the camera begins to work; 6. After use, the control module of the control circuit board activates the micro drive motor, which reverses to rotate the threaded rod; the camera module descends from the second position to the second position. 7. The sealing ring around the protruding hole of the frame abuts against the camera module to prevent dust from entering.

[0067] In the above embodiments, the entire lifting and transmission assembly occupies very little space and has a negligible impact on the overall appearance and weight of the smart glasses.

[0068] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
