[0046] With the development and popularization of AR smart glasses, there are more and more smart glasses on the market. Currently, mainstream AR glasses all adopt diffractive waveguide solutions. Although there are many manufacturers of AR glasses and series products that produce waveguides, the display waveguides used are all from a few major manufacturers. This means that the waveguide solutions of AR glasses from different manufacturers and brands are similar or the same. As the number of products increases, the number of AR glasses waveguides on the market is also increasing. For AR glasses as a whole, the cost of the waveguide accounts for a large proportion of the cost of the glasses. The re-customization of the waveguide for each new product increases the cost for both manufacturers and users. For users' later repairs, they must find the original manufacturer to customize waveguide lenses of special sizes, which is time-consuming and costly, affecting the user experience.

[0047] This application provides an optical waveguide mounting structure and smart glasses to solve the problem of poor battery life in existing smart glasses, which affects user experience. The following will be described in conjunction with the attached... Figure 1-6 Please provide an explanation.

[0048] The optical waveguide mounting structure provided in this application embodiment is referenced. Figure 1 and Figure 2 As shown, it includes a mounting bracket 100 and a limiting member 300. The mounting bracket 100 has a mounting groove 110 for mounting the optical waveguide 200. The limiting member 300 is movably disposed on the mounting bracket 100 and is adapted to move to different positions. The limiting member 300 is used to abut against the optical waveguide 200.

[0049] It is understood that in this embodiment, the shape of the mounting bracket 100 can be designed as a frame structure that can adapt to the shape of the optical waveguide 200. A mounting groove 110 is formed on the inner side of the mounting bracket 100. The size of the mounting groove 110 can be designed to be slightly larger than the size of the optical waveguide 200 to be installed, so as to ensure that the optical waveguide 200 can be smoothly placed into the mounting groove 110.

[0050] The mounting bracket 100 is provided with a limiting component 300, which can effectively fix the optical waveguide 200, prevent the optical waveguide 200 from shifting due to vibration or collision during use, and protect the optical waveguide 200 from damage.

[0051] Furthermore, the limiting member 300 is designed to be movable, for example, it can be sliding, rotating or elastically compressed, so that the user can adjust the position of the limiting member 300 according to the specific specifications of the optical waveguide 200 to be installed.

[0052] With the movable limiting component 300, users can adjust the position or angle of the limiting component 300 according to the actual size and shape of the optical waveguide 200, thereby ensuring that optical waveguides 200 of different specifications can be stably installed on the mounting bracket 100. Users can replace different specifications or types of optical waveguides 200 for installation according to their own wearing needs, achieving personalized adaptation and improving the user experience.

[0053] In an optional embodiment, one end of the limiting member 300 is rotatably disposed on the mounting bracket 100, and the other end abuts against the optical waveguide 200.

[0054] Specifically, one end of the limiting member 300 can be rotatably mounted on the mounting bracket 100 via a bearing or rotating shaft, and the other end of the limiting member 300 can be designed with a contact surface that matches the optical waveguide 200. This contact surface can be flat, convex, or concave to accommodate optical waveguides 200 of different shapes. When the limiting member 300 is rotated into position, it applies appropriate pressure to the optical waveguide 200, ensuring that the optical waveguide 200 assembly is securely located within the mounting groove 110. Users can easily fix the optical waveguide 200 by simply rotating the limiting member 300; the operation is intuitive and convenient.

[0055] In another alternative embodiment, the mounting bracket 100 has a sliding groove that connects to the mounting groove 110, and the limiting member 300 is slidably disposed in the sliding groove.

[0056] For example, the limiting member 300 is designed with a sliding end that can be inserted into a groove and move along the length of the groove. The other end of the limiting member 300 contacts the optical waveguide 200 assembly for fixing and positioning the optical waveguide 200. The user can easily complete the installation of the optical waveguide 200 simply by sliding the limiting member 300 in the groove, without complicated operating steps.

[0057] In one alternative implementation, refer to Figure 4 As shown, there are multiple limiting members 300, which are spaced apart along the circumference of the mounting bracket 100.

[0058] For example, the number of limiting members 300 can be three, four or more to ensure the stable fixation of the optical waveguide 200. The stable fixation of the optical waveguide 200 can ensure the clarity and stability of the image display, thereby improving the overall user experience.

[0059] Multiple limiting components 300 can provide multi-point fixation, effectively preventing the optical waveguide 200 from shifting during the use of smart glasses. Furthermore, the circumferentially spaced limiting components 300 can evenly distribute the pressure between the optical waveguide 200 and the mounting bracket 100, reducing local stress concentration and extending the service life of the optical waveguide 200.

[0060] The multiple limiting members 300 can be evenly or unevenly distributed along the circumference of the mounting bracket 100, and this embodiment does not make a specific limitation on this.

[0061] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, the optical waveguide mounting structure also includes a locking component 400, which is connected to the limiting component 300 and is used to lock the position of the limiting component 300.

[0062] For example, the connection between the locking member 400 and the limiting member 300 can be a threaded connection, a snap-fit ​​connection, or other connection methods. Its main function is to lock the position of the limiting member 300, ensuring that the optical waveguide 200 remains fixed in place after being installed on the mounting bracket 100. This ensures that the limiting member 300 will not loosen during long-term use, enhancing the stability of the entire smart glasses structure. When the user needs to replace the optical waveguide 200, they only need to loosen the locking member 400 to easily rotate the limiting member 300.

[0063] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, the limiting member 300 is provided with a plurality of first locking teeth 310, and a groove 320 is formed between two adjacent first locking teeth 310; the locking member 400 includes a rotating member 410 and an elastic member 420. One end of the rotating member 410 is rotatably disposed on the mounting bracket 100, and the other end is provided with a second locking tooth 411, which engages with the groove 320; one end of the elastic member 420 is connected to the mounting bracket 100, and the other end is connected to the rotating member 410.

[0064] Understandably, in this embodiment, the first locking tooth 310 on the limiting member 300 is similar to the ratchet tooth of a ratchet, and the second locking tooth 411 of the locking member 400 is similar to a pawl. The locking structure of the ratchet and pawl restricts the rotation of the limiting member 300, ensuring the stability of the optical waveguide 200. The elastic member 420 can be an elastic structure such as a spring.

[0065] Specifically, when it is necessary to fix the optical waveguide 200, the user rotates the limiting member 300. The first locking tooth 310 moves with the rotation of the limiting member 300, and finally the second locking tooth 411 engages in the slot 320 between the first locking teeth 310 of the limiting member 300. The elastic member 420 is located on the side of the rotating member 410 away from the limiting member 300. The elastic member 420 is used to apply elastic force to the rotating member 410 to ensure that the second locking tooth 411 remains in the slot 320, thereby fixing the position of the limiting member 300.

[0066] It should be noted that the connection between the elastic element 420 and the mounting bracket 100 and the rotating element 410 can be a fixed connection or an abutment connection, and this embodiment does not specifically limit this.

[0067] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, the rotating component 410 is provided with a positioning post 412, and the elastic component 420 is sleeved on the outside of the positioning post 412. The main function of the positioning post 412 is to ensure that the elastic component 420 is accurately positioned on the rotating component 410, thereby ensuring the normal operation of the locking mechanism of the locking component 400. By providing the positioning post 412, the elastic component 420 is fixed in a specific position, preventing it from shifting or falling off during use.

[0068] In one alternative implementation, refer to Figure 1 and Figure 3 As shown, a soft rubber sleeve 330 is fitted at the end of the limiting member 300, and the limiting member 300 abuts against the optical waveguide 200 through the soft rubber sleeve 330.

[0069] For example, the soft sleeve 330 can be a silicone sleeve. The silicone sleeve has a certain elasticity and cushioning properties, which can reduce the direct collision between the limiting member 300 and the optical waveguide 200, and avoid damage to the optical waveguide 200 caused by impact. In addition, the soft texture of the silicone sleeve can effectively prevent the limiting member 300 from scratching the surface of the optical waveguide 200, and protect the optical performance of the optical waveguide 200.

[0070] In one alternative implementation, refer to Figure 3 As shown, the limiting member 300 has a groove 340, which is used to cooperate with a screwdriver to rotate the limiting member 300.

[0071] For example, the groove 340 can be a slotted groove, a cross groove, or other types. Slotted grooves, cross grooves, and other shapes are common screwdriver interface shapes. Users can rotate the limiting member 300 with just an ordinary screwdriver, which facilitates the installation or removal of the optical waveguide 200 and makes it easy to maintain.

[0072] The optical waveguide mounting structure provided in this application includes a mounting bracket 100 and a limiting member 300. The mounting bracket 100 has a mounting groove 110 for mounting an optical waveguide 200. The limiting member 300 is movably disposed on the mounting bracket 100 and abuts against the optical waveguide 200. By providing a movable limiting member 300 on the mounting bracket 100, the user can adjust the position or angle of the limiting member 300 to limit and fix optical waveguides 200 of different specifications, shapes, and sizes, thereby improving compatibility with optical waveguides 200 of different specifications and enhancing the user experience.

[0073] Secondly, embodiments of this application also provide smart glasses, see reference. Figure 5 and Figure 6 As shown, the smart glasses include a frame 500, an optical waveguide 200, and an optical waveguide mounting structure as described in the above embodiment. The optical waveguide 200 is installed in the mounting groove 110 of the optical waveguide mounting structure to form an integral structure, and the integral structure is then installed on the frame 500.

[0074] The term "smart glasses" as used in this application refers to electronic devices that can be worn on the human eye, including but not limited to commonly available AI glasses, camera glasses, XR glasses, audio glasses, and Bluetooth glasses. Smart glasses can be AR glasses, VR glasses, or MR glasses within the XR category.

[0075] The smart glasses in this embodiment are compatible with waveguides 200 of different profiles on the market. Users do not need to customize special-sized waveguide 200 lenses for later maintenance. They only need to use the existing waveguide 200 for installation, which greatly reduces time and cost.

[0076] In one alternative implementation, refer to Figure 5 and Figure 6 As shown, the frame 500 is provided with a decorative part 510, which is detachably connected to the frame 500, and a receiving groove is defined between the frame 500 and the decorative part 510, and the optical waveguide mounting structure is installed in the receiving groove.

[0077] For example, the detachable connection between the decorative element 510 and the frame 500 can be a snap-on, screw-fixed, magnetic, or other mechanical connection method, and the decorative element 510 is located at the front of the smart glasses (i.e. the side of the frame 500 away from the human eye) and serves a decorative function.

[0078] A receiving groove is formed between the frame 500 and the decorative part 510 for installing and fixing the optical waveguide mounting structure. The position and size of the receiving groove can be designed to match the size and installation requirements of the optical waveguide mounting structure. The optical waveguide mounting structure is installed in the receiving groove and can be installed on the frame 500 by adhesive application, clips, or threaded connection, ensuring that it will not shift during use. When it is necessary to replace the optical waveguide 200, simply remove the decorative part 510, and the user can use a screwdriver to loosen the limiting part 300 to facilitate the disassembly and replacement of the optical waveguide 200. After replacement, the decorative part 510 can be reinstalled.

[0079] In one alternative implementation, refer to Figure 5 and Figure 6 As shown, the smart glasses also include an optical engine 600, which is mounted on the frame 500, and the optical engine 600 is configured to correspond to the coupling area of ​​the optical waveguide 200.

[0080] It is understandable that the optical engine 600 is the imaging component of the smart glasses, which may include a microdisplay, optical elements (such as lenses, prisms, etc.) and a light source, used to generate images and transmit them to the optical waveguide 200. The position of the optical engine 600 needs to be accurately aligned with the coupling area of ​​the optical waveguide 200 to ensure that the image can be effectively transmitted and displayed.

[0081] The frame 500 may include a front frame 520 and a rear shell 530. The optical engine 600 and the rear shell 530 can be installed on the rear side of the front frame 520. An installation space is formed between the front frame 520 and the rear shell 530 for installing the optical engine 600. The structure is compact and reduces the overall space occupation.

[0082] It is understood that since the optical waveguide mounting structure has the beneficial effects of the above embodiments, the smart glasses also have the above beneficial effects. The specific implementation method can be referred to the above embodiments, and this embodiment will not be repeated.

[0083] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should all be covered within the protection scope of this application.
