Description

Technical Field

[0001] This application relates to the field of augmented reality technology, and in particular to an AR glasses and its temples. Background Technology

[0002] In recent years, the smart glasses industry has developed rapidly. Among them, augmented reality (AR) glasses are regarded as a key entry point to the era of spatial computing. With the characteristics of "virtual and real integration, seamless interaction, and full-scene adaptation", they are rapidly penetrating various application scenarios.

[0003] AR glasses feature near-eye display capabilities, typically comprising a waveguide and an optical engine (or light engine). The waveguide is a special lens with an input and output region. The optical engine, acting as the image source for the waveguide, consists of a screen and a projection lens. The screen generates the image to be displayed, and the projection lens projects the image onto an infinity or specified distance. During use, light carrying image information, output from the optical engine, enters the waveguide through the input region, travels a predetermined distance via total internal reflection, and then exits through the output region to reach the eye, forming the image on the retina. Simultaneously, because the waveguide has excellent transmittance to ambient light, the eye can simultaneously see both real-world objects and the image output by the optical engine, achieving a seamless blending of reality and virtuality.

[0004] In the existing technology, in order to meet the coordination between the optomechanic and the optical waveguide, it is necessary to set up a complex installation structure for the optomechanic or between the optomechanic and the optical waveguide, or to appropriately reduce the installation complexity by sacrificing some complexity. Summary of the Invention

[0005] In view of this, the embodiments of this application aim to provide an AR glasses and its temples that can reduce the complexity of the optical engine mounting structure while meeting the requirements of precision optical engine assembly.

[0006] In a first aspect, the AR glasses temple provided in this application includes a temple body and further includes: a temple extension having an inner cavity, the first end of the temple extension being disposed at the head end of the temple body; an optical engine bracket disposed in the inner cavity of the temple extension, the optical engine bracket forming at least one limiting relationship with the head end of the temple body and the temple extension respectively; and an optical engine, an image source for the AR glasses, which is mounted on the optical engine bracket at a preset angle.

[0007] Secondly, the AR glasses provided in this application embodiment include a frame, a first temple, a second temple, a first lens, and a second lens. The frame includes a frame body, the first temple is disposed at a first end of the frame body, the second temple is disposed at a second end of the frame body, the first lens is disposed on a first lower side of the frame body and corresponds to the first temple, and the second lens is disposed on a second lower side of the frame body and corresponds to the second temple. The first temple is the aforementioned AR glasses temple, and the first lens is a waveguide. When the first temple is in an open state, the optomechanical mechanism in the first temple and the coupling area of ​​the first lens form a coupled incident engagement.

[0008] In summary, this application proposes a novel AR glasses temple design and AR product configuration. By adopting the solution of this application, the optical engine is mounted on the temple rather than adjacent to the waveguide, which relatively decouples the mounting structure of the optical engine and the waveguide, facilitating a lightweight mounting method and reducing the complexity of the mounting structure. Furthermore, the optical engine is mounted via an optical engine bracket, which forms multiple limiting positions on the temple body and temple extension, enabling precise assembly of the optical engine. Additionally, the optical engine and its bracket are integrated into the temple body via the temple extension, simplifying temple design and facilitating manufacturing, assembly, and maintenance.

[0009] In addition, in at least one specific embodiment of the present application, the power supply unit, the first line, the motherboard unit, the second line and the optical engine are centrally located on the temple, which can simplify the connection structure between the temple and the frame. At the same time, the wiring layout and optical engine attachment structure on the frame can be eliminated, which helps to simplify the structure of the frame to the greatest extent. This can significantly improve the design freedom of the front frame while significantly reducing the weight of the entire glasses, thereby effectively improving the user's wearing experience.

[0010] The power supply unit, the first line, the main board unit, and the second line are arranged in sections on the temple body, or the shape of the temple body is divided into sections, that is, it is larger at both ends and smaller in the middle. This can optimize the ergonomics of the temple and also help the temple to adopt more flexible methods (such as using folding temples). This can significantly improve the user's wearing experience while increasing the design freedom of the temple.

[0011] All electronic components, including the power supply unit, optical engine, motherboard unit, and circuitry, are placed on the temples. The temples and frame can be assembled in a simplified manner. During manufacturing or supply chain collaboration, the temples can be manufactured, assembled, and tested by specialized electronics manufacturers, while the main frame can be customized in different styles by established traditional eyewear manufacturers before final assembly. This not only facilitates the manufacturing, assembly, and maintenance of each component and the entire device but also effectively improves the level of division of labor and reduces costs. Furthermore, from the perspective of the entire device, the integrated design helps simplify and lighten the frame, as well as simplify the connection between the temples and the frame. Combined with the aforementioned technological advantages, this helps AR glasses achieve an extremely lightweight and stylish design, thereby accelerating the market penetration of AR glasses.

[0012] Furthermore, in at least one implementation of the embodiments of this application, the entire AR glasses device can be controlled to weigh less than 30 grams (30g). In at least one implementation, by improving the structure of the head piece and the frame, both structural simplicity and stable support can be achieved simultaneously. Further technical effects of other implementations are described in the specific embodiments. Attached Figure Description

Second lens 6 First Bolt 7 Second bolt Detailed Implementation To make the objectives, solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be fully described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0015] Advances have been made in technologies related to reducing the complexity of AR assembly, reducing the overall weight of AR glasses, simplifying the arrangement of the front frame, and simplifying the matching between the optical engine and the waveguide (lens). For example, in traditional AR binocular display solutions, each waveguide is equipped with a separate optical engine. However, in some solutions, a single optical engine is used to provide image sources for two waveguides simultaneously, thus saving the weight of at least one optical engine and partially simplifying the assembly process.

[0016] For example, in traditional designs where the optical engine is mounted on the frame, since the battery and motherboard (electronic components) are located on the temple, the cable between the optical engine and the motherboard—the FPC (Flexible Printed Circuit) serving as the signal and / or electrical connection—needs to be arranged on both the frame and the temple, passing through the hinge connecting the frame and temple. Because the hinge is repeatedly folded during use, the FPC is prone to loosening or breaking. Furthermore, to meet the cable handling requirements of the hinge, a significant volume is required near the hinge. Some designs partially address these issues by mounting the optical engine on the temple, a typical example being the design disclosed in patent document CN111736352A. However, this design is solely to prevent damage to the optical engine cable due to frequent movement. While it objectively helps reduce cable arrangement on the frame, overall, the structures of these designs—whether temple-mounted, temple-mounted, or frame-mounted—are complex and bulky, making them difficult to directly apply for reducing assembly complexity and overall weight. The solution disclosed in patent document CN216351549U also adopts the idea of ​​placing the optical engine on the temple, aiming to reduce the size and structural complexity of the hinge. However, other aspects, especially those related to reducing assembly complexity, are disclosed in a limited way. Ergonomics are not considered, and it is difficult to provide much reference in terms of reducing assembly complexity, lightweight design, and improving wearing experience. In addition, the optical engine used in this solution is a unique modified type, rather than the mainstream type in the industry. In addition, with the rapid development of the industry in recent years, the size, performance, precision, and assembly requirements of optical engines are no longer comparable to what they used to be. Therefore, the specific setting of the optical engine is difficult to adapt to current needs.

[0017] This application aims to propose a novel lightweight product configuration. By optimizing core components or links such as the temples, it seeks to minimize the manufacturing, assembly, and maintenance difficulties of AR glasses without affecting near-eye display functionality. This includes reducing the weight of the AR glasses, optimizing ergonomics, and effectively improving the user's wearing experience. The application also seeks breakthroughs in manufacturing, assembly, maintenance, supply chain collaboration, cost, and design freedom, thereby accelerating the market adoption of AR glasses. Furthermore, the applicant's research indicates that if the weight of AR glasses can be controlled within 30g, it will significantly improve the user's wearing experience and wearing time; therefore, extreme lightweighting is also a key consideration.

[0018] Therefore, the embodiments of this application include an AR glasses temple and AR glasses. For ease of understanding and description, the following also incorporates... Figures 1 to 26 The explanation will focus on the temples and frame 1 of the AR glasses, while other aspects will be supplemented and extended based on this.

[0019] See Figure 1 , Figure 2 and Figure 3 As shown, the AR glasses 100 provided in this embodiment may include a frame 1, a first temple 2, a second temple 3, a first lens 4, a second lens 5, a first bolt 6, and a second bolt 7. In this embodiment, the first temple 2 is the right temple (the division of left, right, up, down, front, and back is based on the user's viewing angle after wearing the glasses, the same below), the second temple 3 is the left temple, the first lens 4 is the right lens, and the second lens 5 is the left lens. The first temple 2 can be set at the first end (right end) of the frame 1 by the first bolt 6, and the second temple 3 can be set at the second end (left end) of the frame 2 by the second bolt 7. The first temple 2 and the second temple 3 are symmetrical to each other in shape. The first lens 4 is set at the first lower side (lower right side) of the frame 1, and the second lens 5 is set at the second lower side (lower left side) of the frame 1. The first temple 2 may be one implementation of the AR glasses temple in this embodiment.

[0020] Specifically, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the first temple 2 may include a first temple body 21, a first temple extension 22, a protective light-transmitting sheet 23, an optical engine bracket 24, an optical engine 25, a second circuit 26, a mainboard unit 27, a first circuit 28, and a power supply unit 29. The first temple body 21 has a receiving cavity, combined with... Figure 6 and Figure 7As shown, the first temple body 21 can be roughly divided into a head region 201, a middle region 202 and a tail region 203 in the extension direction (the end closer to the frame after assembly is the head end, and the area near it is the head region; the end farther from the frame is the tail end, and the area near it is the tail region, and so on).

[0021] The motherboard unit 27 can be disposed in the receiving cavity of the head region 201 of the first temple body 21. The motherboard unit 27 can integrate or configure a touch unit 271. Correspondingly, a touch area is formed on the outer wall of the first temple body 21 corresponding to the touch unit 271 for acquiring user touch input. The power supply unit 29 can be disposed in the receiving cavity of the tail region 203 of the first temple body 21. The first line 28 can extend in the receiving cavity of the middle region 202 of the first temple body 21, with its two ends connected to the motherboard unit 27 and the power supply unit 29, respectively. The optical engine 25 can be disposed at the head end of the first temple body 21, and the two ends of the second line 26 are connected to the motherboard unit 27 and the optical engine 25, respectively. The first line 28 can serve as a signal and electrical connection cable between the power supply unit 29 and the motherboard unit 27, and the second line 26 can serve as a signal and electrical connection cable between the motherboard unit 27 and the optical engine 25. In specific implementations, the first line 28 and the second line 26 can be FPCs. In addition, the external dimensions of the first temple body 21 can be generally larger at both ends and smaller in the middle in the extension direction, that is, the head region 201 and the tail region 203 are large and the middle region 202 is small. In one case, the external dimensions can refer to the observable height of each part of the temple, such as the vertical height of each part of the temple of the glasses as observed by a third person from the side when the user is wearing AR glasses 100 normally. In another case, the external dimensions can refer to the thickness of each part of the temple.

[0022] The first temple extension 22 can be a cylindrical structure containing a cavity and extending through the front and rear, used to accommodate the optical engine support 24 and the optical engine 25. The first temple extension 22 is connected to the head end of the first temple body 21, and can function as an extension of the first temple 21 both functionally and visually. In this embodiment, the first lens 4 is a waveguide sheet, on which a coupling-in region 41 and a coupling-out region 42 are provided. To facilitate installation and positioning, an external structure (not shown in the figure) is formed near the coupling-in region 41. The optical engine 25 is used as the image source of the AR glasses 100. That is, during use, when the first temple 21 is in the open state, the optical engine 25 can form a coupled incident engagement with the coupling-in region 41 of the first lens 4, and the light output by the optical engine 25 can enter the coupling-in region 41 of the first lens 4. Figure 14 , Figure 16 , Figure 17 , Figure 18 and Figure 19As shown, a connecting seat 2123 can be provided at the head end of the first temple body 21, and an optical engine bracket 24 can be used to house the optical engine 25. The optical engine bracket 24 can be set as a whole in the cavity of the first temple extension 22 at a preset angle. The first end (tail end / tail side) of the optical engine bracket 24 can be connected to the connecting seat 2123 on the first temple body 21 to form a rotation limit. The second end (head end / tail side) of the optical engine bracket 24 can be connected to the interior of the first temple extension 22 to form a positioning match and rotation limit. The rotation limit refers to the limitation achieved by the structural cooperation between them to prevent the optical engine bracket 24 from being positioned relative to the first temple body 21. The temple body 21 can rotate relative to the first temple extension 22. The positioning and matching means that they provide a specific and precise positioning connection position so that the optical engine 25 can meet the preset angle arrangement requirements after the two are assembled. The first end (tail end) of the first temple extension 22 can be set at the connecting seat 2123 at the head end of the first temple body 21. The protective light-transmitting sheet 23 can be set at the second end (head end) of the first temple extension 22. Due to its light transmission characteristics, the protective light-transmitting sheet 23 can not affect the light emission of the optical engine 25. At the same time, together with the first temple extension 22, it can prevent the optical engine 25 from being exposed and easily contaminated and damaged.

[0023] In specific implementation, combined with Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, the first temple body 21 may include a first housing 211 and a second housing 212. The first housing 211 and the second housing 212 can be assembled by a snap-fit ​​connection to form a first temple body 21 containing an inner cavity. For example, the first housing 211 may be an extended housing structure with a first recess 2110, on the inner wall of which a plurality of snap-fit ​​posts 2111 are provided. The second housing 212 may be an extended housing structure with a second recess 2120, on the inner wall of which a plurality of corresponding snap-fit ​​seats 2121 are provided. The first housing 211 and the second housing 212 can be snap-fit ​​connected by the snap-fit ​​posts 2111, the snap-fit ​​seats 2121, and the attached housing edge steps (not shown in the figure). The space between the first recess 2110 and the second recess 2120 forms the receiving cavity of the first temple body 21.

[0024] In specific implementation, combined with Figure 13 and Figure 14As shown, the connector 2123 can be disposed at the head end of the second housing 212. The connector 2123 may include a connector 2124, which is disposed at the head end of the second housing 212. The connector 2124 may adopt a cylindrical joint structure. The outer circumferential surface of the connector 2124 may be provided with a first limiting groove 2127, a second limiting groove 2129, and an optical engine bracket mounting port 2128 at intervals. In addition, a partition 2125 may be provided in the inner radial direction of the connector 2124, and a wire passage port 2126 may be provided on the partition 2125. This arrangement can not only meet the wire passage requirements of the second line 26, but also isolate the electronic components of the first temple extension 22 from the optical engine 25, reduce mutual interference, and meet the requirements of anti-interference, protection, and heat dissipation.

[0025] In specific implementation, such as Figure 16 and Figure 17 As shown, the first temple extension 22 may include a cylindrical body 220, which has a first opening 224 and a second opening 225. Its inner cavity extends through the two openings. The first opening 224 is a partially open structure. The end of the cylindrical body 220 where the second opening 225 is located is the tail end (i.e., the tail end of the first temple extension 22), and the end of the cylindrical body 220 where the first opening 224 is located is the head end (i.e., the head end of the first temple extension 22). A first temple hinge lug 221 may be provided on the outer side of the cylindrical body 220 for connecting the first temple 2 to the frame 1, i.e., the first temple 2 is connected to the frame 1 via the first temple hinge lug 221 and the first bolt 6. The inner wall of the cylindrical body 220 may have circumferentially... The cylindrical body 220 is provided with a first limiting protrusion 2203 and a second limiting protrusion 2202 that are generally aligned with the extending direction of the cylindrical body 220. The first limiting protrusion 2203 can match the first limiting groove 2127 on the connector 2124, and the second limiting protrusion 2202 can match the second limiting groove 2129 on the connector 2124. An outer mounting part 2201 can be provided on the outer side wall of the head end of the cylindrical body 220 around the first opening 224 for the installation of the protective light-transmitting sheet 23. An assembly area for the optical engine bracket 24 can be provided on the inner side wall of the head end of the cylindrical body 220 around the first opening 224. The arrangement of the optical engine bracket 24 can be described in the following description of the specific implementation of the optical engine bracket 24.

[0026] In specific implementation, combined with Figure 18 and Figure 19As shown, the optical engine bracket 24 may include a base support 241, a vertical support 242, and a housing support 243. The base support 241 may extend generally laterally, and its first end (the free end, which also serves as the first or tail end of the optical engine bracket 24) can be used as the mounting end. The vertical support 242 is located on the upper side of its second end and is generally vertically bracket-shaped. The housing support 243 is generally cylindrical and is located on the side of the vertical support 242 away from the base support 241. During use, the optical engine 25 is mounted on the optical engine bracket 24. The vertical support 242 can be used to house or partially house the screen of the optical engine 25, providing protection for the screen. The housing support 243 can be used to house the projection lens of the optical engine 25, providing support and protection for the projection lens. The base support 241 is the overall bottom support and can also provide some support for peripheral components of the optical engine, such as the second line 26. Combined with... Figure 18 and Figure 17 As shown, to improve the precision assembly and positioning effect of the optical engine 25, a first positioning limiting part 2431 and a second positioning limiting part 2432 can be provided at intervals on the outer periphery of the support 243 of the optical engine bracket 24. The first positioning limiting part 2431 focuses on top positioning and / or limiting, and the second positioning limiting part 2432 focuses on side positioning and / or limiting. Correspondingly, a support mounting area 2204 can be provided on the inner side wall of the head end of the cylindrical body 220 of the first temple extension 22 at the position surrounding the first opening 224. The support mounting area 2204 is provided with a first positioning limiting groove 2205 and a second positioning limiting groove 2206 at intervals in the circumferential direction. The positioning groove 2205 matches the first positioning limiting part 2431, and the second positioning limiting groove 2206 matches the second positioning limiting part 2432. In this way, after assembly, the second end of the optical engine bracket 24 (the free end of the support 243, i.e. the end of the support 243 away from the upright support 242) can be installed at the corresponding position on the inner side wall of the head end of the first temple extension 22. This structure allows the optical engine to adjust the positioning limiting relationship between the first positioning limiting part 2431 and the first positioning limiting groove 2205 and / or the positioning limiting relationship between the second positioning limiting part 2432 and the second positioning limiting groove 2206 during installation, so that the optical engine 25 can be arranged according to the design or preset angle.

[0027] To facilitate understanding, the overall assembly sequence of the first temple 2 is explained below. (Combined with...) Figures 9 to 13 As shown, in the assembly sequence of the relevant parts of the first temple body 21, the first line 28, the main board unit 27, the second line 26, and the power supply unit 29 can be sequentially installed at corresponding positions on the second housing 212 of the first temple body 21. One end of the first line 28 extends through the wire passage on the connector 2123. Then, the first housing 211 is fastened to the second housing 212, thereby completing the assembly of the first temple body 21. Furthermore, in conjunction with... Figure 9 , Figure 14 , Figure 17 , Figure 18 As shown, in the assembly sequence of the relevant parts of the first temple extension 22, the optical engine 25 can be first installed on the optical engine bracket 24. Then, the end corresponding to the second opening 225 of the first temple extension 22 is fitted onto the optical engine bracket 24 from front to back. During this process, the positioning and limiting relationship between the first positioning limiting part 2431 on the support 243 of the optical engine bracket 24 and the first positioning limiting groove 2205 in the first temple extension 22, and / or the positioning and limiting relationship between the second positioning limiting part 2432 and the second positioning limiting groove 2206, is adjusted for precise positioning. The optical engine angle is pre-adjusted. Then, the end of the second line 26 extending from the cable port is connected to the cable connector of the optical engine 25. Finally, the optical engine... The first end of the base support 241 of the frame 24 is installed on the optical engine bracket mounting port 2128 on the connecting seat 2123 of the first temple body 21. Finally, the first temple extension 22 is further fitted onto the connecting seat 2123 of the first temple body 21, so that the first limiting protrusion 2203 and the second limiting protrusion 2202 on the inner sidewall of the first temple extension 22 are respectively matched with the first limiting groove 2127 and the second limiting groove 2129 on the outer sidewall of the cylindrical body 220 of the connecting seat 2123, thereby realizing the installation of the first temple extension 22 at the head end of the first temple body 21. In addition, the protective light-transmitting sheet 23 can be installed on the outer part 2201 of the first temple extension 22. This completes the overall assembly of the first temple 2.

[0028] In the AR glasses 100 of this embodiment, the second lens 5 can be a non-waveguide sheet (but its shape is the same as that of the first lens 4 as the waveguide sheet), and the corresponding second temple 3 is a non-AR glasses temple. Specifically, the second temple 3 does not contain electronic components such as the optomechanical system 25. In order to balance the weight of the left and right sides of the AR glasses 100, especially between the second temple 3 and the first temple 2, when wearing the glasses, the second temple 3 can be provided with a counterweight or other functional modules can be integrated in the second temple 3. For example, it can be a sensor unit and / or a camera unit and / or a thermal imaging unit and / or a depth camera unit, as well as a power supply that provides power to the above units.

[0029] In specific implementation, combined with Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the second temple 3 can adopt the same configuration as the first temple 2; specifically, the second temple 2 can include a second temple body 31 and a second temple extension 32 disposed at the head end of the second temple body 31; a second temple hinge lug 321 can be provided on the second temple extension 32 for connecting the second temple 3 to the frame 1, that is, the second temple 3 can be connected to the frame 1 through the second temple hinge lug 321 and the second bolt 7; the second temple body 31 can also adopt the following configuration: Figure 12 and Figure 13 The two housings shown are assembled together. The second temple extension 32 can also adopt a structure similar to the first temple extension 22. Correspondingly, the head end of the second temple body 31 can also be provided with a structure similar to the connecting seat 2123. It can be understood that since the second temple 3 does not contain the optical engine 25, the second temple extension 32 does not need to include the optical engine bracket 24 and the optical engine 25. Therefore, the second temple extension 32 does not need to be provided with a structure for mounting the optical engine bracket 24, and the connecting seat at the head end of the second temple body 31 does not need to be provided with a structure for mounting the optical engine bracket 24.

[0030] Combination Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 24As shown, the eyeglass frame 1 in this embodiment may include an eyeglass frame body 11, a first post head 12, a second post head 13, a first lens holder 14, a second lens holder 15, a first nose pad assembly 16, and a second nose pad assembly 17. The eyeglass frame body 11 may include a first part 111a and a second part 111b of the eyeglass frame body that are connected and symmetrically arranged from left to right. The first post head 12 can be disposed at the first end (right end, i.e. the end of the first part 111a of the frame body) of the frame body 11. The first post head 12 can be used to connect with the first temple 2. For example, the first temple hinge ear 221 on the first temple extension 22 of the first temple 2 can be connected to the first post head 12 by the first bolt 6. The first post head 12 can be disposed at the first end (right end, i.e. the end of the first part 111a of the frame body) of the frame body 11. The second post head 13 can be used to connect with the second temple 3. For example, the first temple hinge ear 321 on the second temple extension 32 of the second temple 3 can be connected to the second post head 13 by the second bolt 7. The first lens holder 14 can be disposed on the first lower side (lower right side, i.e., the lower side of the first part 111a of the frame body) of the frame body 11 for mounting the first lens 4; the second lens holder 15 can be disposed on the second lower side (lower left side, i.e., the lower side of the second part 111b of the frame body) of the frame body 11 for mounting the second lens 5. The first nose pad assembly 16 and the second nose pad assembly 17 both include a nose pad holder and a nose pad disposed on the nose pad holder. The nose pad holder can be disposed near the lower rear of the middle part of the frame body 11 or on the lower rear of the middle part. Since the two parts of the frame body 11 are symmetrical, the first post 12 and the second post 13 are generally symmetrically arranged at both ends of the frame body 11. The arrangement of the first lens holder 14 and the second lens holder 15, as well as the arrangement of the first nose pad assembly 16 and the second nose pad assembly 17, are also symmetrical. The following description focuses on the right part of the frame 1 (the first part 111a of the frame body, the first post 12, the first lens holder 14, the first nose pad assembly 16, etc.). The implementation of the left part of the frame 1 can be found in the description of the right part of the frame 1.

[0031] In specific implementation, such as Figure 23 As shown, the first post head component 12 may include a first post head 1211, a first clamping and fixing plate 121, and a first supporting and fixing plate 122. The first clamping and fixing plate 121 is generally an irregularly wide plate, and the first supporting and fixing plate 122 is generally an extended and bent narrow plate. One end of the first supporting and fixing plate 122 is connected to one end of the first clamping and fixing plate 122. The first clamping and fixing plate 121 and the first supporting and fixing plate 122 may be on different horizontal planes. In this embodiment, the first post head 1211 is disposed on the first clamping and fixing plate 121, and the first post head 1211 is used for the hinged installation of the first temple 2. Figure 20 and Figure 21As shown, the end of the first part 111a of the frame body is provided with a first clamping and fixing area 113a, a first supporting and fixing area, and a first clamping and supporting area with a circumferential step limiting part. The first supporting and fixing area is generally located on the lower right side of the first clamping and fixing area 113a, and the first clamping and supporting area with the circumferential step limiting part is generally located on the upper right side of the first clamping and fixing area 113a. The first clamping and fixing plate 121 is installed behind the first clamping and fixing area 113a and forms a clamping opening with the first clamping and fixing area 113a. The two cooperate through the clamping opening to clamp the outer structure of the coupling area of ​​the first lens 4. The first supporting and fixing plate 122 is installed in the first supporting and fixing area and cooperates with the circumferential step limiting part to circumferentially support the outer structure of the coupling area of ​​the first lens 4. By adopting the above solution, the first post head 12 can simultaneously achieve the connection of the first temple 2, the clamping and fixing of the outer structure of the first lens 4 in the coupling area, and the circumferential support and fixing of the outer structure of the first lens 4 in the coupling area. This can greatly simplify the structural complexity of the frame 1 (frame body 11). Combined with Figures 21 to 24 As shown, in a more specific embodiment, in order to install the first pile head 12 on the right end of the frame body 11, a right first mounting hole 114a and a right second mounting hole 115a, which generally extend front to back, can be provided above the first clamping and fixing area 113a. The first clamping and fixing plate 121 is provided with a first pile head mounting post 1212 and a second pile head mounting post 1213, which also generally extend front to back. Thus, the first clamping and fixing plate 121 can be installed using the right first mounting hole 114a, the first pile head mounting post 1212, the right second mounting hole 115a, and the second pile head mounting post 1213. The first pile head 12 is installed at the right end of the frame body 11, thus achieving fixation and limiting. Additionally, a right third mounting hole 117a can be provided on the first support fixing area at the right end of the frame body 11, and a first pile head limiting post 1221 can be provided at a corresponding position on the first support fixing plate 122 of the first pile head 12. The first fixing support plate 122 can be installed through this right third mounting hole 117a and the first pile head limiting post 1221, thereby achieving the second position of the first pile head 12 at the right end of the frame body 11. In this way, the fixation, limiting, and support of the first pile head 12 are achieved overall.

[0032] In specific implementation, combined with Figure 22As shown, the first lens holder 14 is located on the lower right side (the lower right side, i.e., the lower side of the first part 111a of the frame body) of the frame body 11. The first end (right end) of the first lens holder 14 can be provided with a lens holder first fastening hole 141 that extends generally vertically. The first fixed support plate 122 of the first post member 12 is provided with a post head first fastening hole 1222 that extends generally vertically. Thus, the frame 1 can also include a first fastener (not shown in the figure). Through the first fastener (e.g., a bolt), the lens holder first fastening hole 141 and the post head first fastening hole 1222 (e.g., a threaded hole), the right end of the first lens holder 14 can be installed and fixed on the frame 1 (first post member 12 / frame body 11). With this solution, the first temple 2 can be connected, the first lens 4 can be clamped and fixed to the structure outside the coupling area, the first lens 4 can be circumferentially supported and fixed to the structure outside the coupling area, and the first lens bracket 14 can be installed and fixed simultaneously through the first post 12. This can achieve installation and fixation and multiple limiting while further simplifying the structural complexity of the frame 1 (frame body 11).

[0033] In addition, the second end (left end) of the first lens holder 14 can be provided with a generally vertically extending second lens holder fastening hole 142, and the first nose pad assembly 16 is provided with a generally vertically extending first nose pad fastening hole. Thus, the frame 1 can also include a second fastener (not shown in the figure), and a right fourth mounting hole 119a is provided in the first part 111a of the frame body near its middle position. Through the second fastener (e.g., bolt), the first nose pad fastening hole, the second lens holder fastening hole 142, and the right fourth mounting hole 119a (e.g., threaded hole), the left end of the first lens holder 14 and the first nose pad assembly 16 can be installed and fixed on the frame 1 (frame body 11) at the same time.

[0034] The second part 111b of the frame body and its second clamping and fixing area 113b, second fixing support area, second clamping and support area with circumferential step limiting part, left first mounting hole 114b, left second mounting hole 115b, left third mounting hole 117b, left fourth mounting hole 119b, second post head 13 and its specific structure, the installation method of the second lens bracket 15, and the specific implementation method of the installation method of the second nose pad assembly 17 can be found in the aforementioned description of the first part of the frame, and will not be repeated here.

[0035] To facilitate understanding, the overall assembly sequence of the frame 1 is explained below. First, place the first lens 4 and the second lens 5 in their respective mounting areas on the frame body 11. The outer structure of the coupling area of ​​the first lens 4 is located in the first clamping and fixing area 113a, and the outer structure of the coupling area of ​​the second lens 5 (the second lens is not a waveguide, but its shape also has an outer structure of coupling area similar to that of the first lens 4) is located in the second clamping and fixing area 113b. Then, install the first post head 12 and the second post head 13 at both ends of the frame body 1, so that the first post head 12 and the second post head 13 clamp and circumferentially support the outer structure of coupling area of ​​the first lens 4 and the outer structure of coupling area of ​​the second lens 5, respectively. The first lens holder 14 and the second lens holder 15 support the lower sides of the first lens 4 and the second lens 5 from bottom to top, respectively. Then, the first ends of the two lens holders are respectively installed on the first post head 12 and the second post head 13 by corresponding fasteners. In addition, the fastening holes of the nose pad bracket of the first nose pad assembly 16 and the nose pad bracket of the second nose pad assembly 17 are matched and aligned with the fastening holes on the second ends of the two lens holders and the mounting holes (119a / 119b) near the middle position on the frame body, respectively. Finally, the three are installed and fixed by corresponding fasteners, thereby realizing the overall assembly of the frame 1. In addition, the hinge ears (221 and 321) on the temple extensions of the two temples are hinged to the post heads on the two post heads by the first bolt 6 and the second bolt 7, respectively.

[0036] During use, the user wears the AR glasses 100 on their head with both temples open. At this time, the optical engine 25 in the first temple 2, under the control of the mainboard unit 27, outputs light carrying image information. This light passes through the protective light-transmitting plate 23 and enters the coupling zone 41 of the first lens 4. After diffraction in the coupling zone, it undergoes total internal reflection and propagates a predetermined distance. Upon reaching the coupling zone 42 of the first lens 4, it is diffracted again and exits the lens, entering the user's eye. The user can then see the image information carried by this light. Simultaneously, due to the lens's light-transmitting properties, the user can also see the real world in front of them. The user can use their right hand to touch the touch area 272 to adjust the image information or control the working state of the AR glasses 100.

[0037] In summary, the temple design, frame design, and eyeglasses design adopted in this application can simultaneously achieve multiple direct technical effects and bring about a variety of progressive effects, forming an industry-leading product configuration. Firstly, the optical engine 25 is mounted on the temple, rather than adjacent to the optical waveguide, which relatively decouples the mounting structure of the optical engine 25 and the optical waveguide, facilitating a simpler installation method and reducing the complexity of the mounting structure. Furthermore, the optical engine is mounted via the optical engine bracket 24, which can form multiple limiting positions, thereby enabling precise assembly of the optical engine. Finally, the optical engine 25 and the optical engine bracket 24 are integrally mounted at the head end of the temple body via a temple extension, which helps simplify temple design and facilitates manufacturing, assembly, and maintenance. In addition, the power supply unit 29, the first circuit 28, the main board unit 27, the second circuit 26, and the optical engine 25 can be centrally located on the temple. A simple hinge scheme can be used between the temple and the frame, effectively simplifying the hinge structure. This overcomes the problems of overly complex, bulky, and heavy hinge structures in existing technologies. Since all electronic components are concentrated on the temple, there is no need for FPC or other wiring on the frame, nor for auxiliary structures such as optical engine mounting bases. This solves the problems of overly complex, large, and heavy frame components in existing technologies, helping to optimize and simplify the spatial layout and configuration of the frame to the greatest extent and / or reduce rigid constraints on frame design, significantly increasing the front frame design space. This makes it easier to make the frame look like a traditional eyeglass frame, while also making disassembly and maintenance convenient. This reduces the complexity of manufacturing, assembly, and maintenance, significantly increases the freedom of front frame design, significantly reduces the weight of the entire eyeglasses, and effectively improves the user's wearing experience.

[0038] Secondly, based on this, the power supply unit 29, the first line 28, the main board unit 27, and the second line 26 can be arranged in sections on the temple body (i.e., the head area 201, the middle area 202, and the tail area 203). The middle area mainly contains the first line 28, which helps to achieve a slimmer temple shape and a more flexible temple shape. For example, the middle temple can be further foldable. The power supply unit 29 is placed at the rear of the tail area 203, and the main board unit 27, the optical engine 25, and its auxiliary components are placed at the front of the head area 201. This helps to separate the two heavier parts and place them at the front and back, thus optimizing ergonomics and significantly improving the wearing experience. In addition, the temple body shape changes in sections (its external dimensions in the extension direction are larger at both ends and smaller in the middle, i.e., the head area 201 and the tail area 203 are large, and the middle area 202 is small). This also optimizes ergonomics and helps to achieve a more streamlined, more natural, and more stylish temple shape, thus improving the overall wearing experience in terms of both functionality and visual effect. Therefore, the temple setting method of this application embodiment can optimize the ergonomics of the temple and also help the temple to adopt a more flexible approach, which can significantly improve the user's wearing experience while increasing the design freedom of the temple.

[0039] Thirdly, based on this, the optical engine 25 is installed in the temple extension via the optical engine bracket 24 and assembled to the head end of the temple via the temple extension. First, by reserving a certain design redundancy, the optical engine can be easily assembled and disassembled for maintenance without affecting the coupling and incident coordination between the optical engine and the waveguide lens in near-eye display. Second, considering that optical engines are becoming increasingly precise and smaller in size, the requirements for assembly precision and ease of assembly are becoming increasingly higher. Simultaneously, considering the relative isolation requirement between the optical engine and the mainboard unit, existing related solutions are difficult to meet the requirements. In this embodiment, the optical engine bracket 24 not only provides support or a placement position for the optical engine 25, but also specifically meets the requirements for fixed positioning with the temple body, convenient adjustable assembly of the optical engine 25, and positioning with the temple extension, improving the assemblability of the optical engine 25 and the optical engine bracket 24. This facilitates a single installation that ensures the optical engine 25 meets the design angle requirements, while also providing a stable support foundation for its stable operation. The optical engine assembly scheme of this embodiment can support optical engines with dimensions of less than 0.1 cc (cubic centimeters). Furthermore, the optical engine 25 and the mainboard unit 27 are relatively isolated via a connector 2123, which reduces mutual interference between the two parts and meets requirements for anti-interference, protection, and heat dissipation. Moreover, the optical engine is mounted at the head end of the temple via a temple extension. The temple extension and the protective light-transmitting sheet provide protection for the optical engine 25, preventing it from being affected by the external environment. The temple can also be easily hinged to the frame 1 via the hinge lugs on the temple extension. After hinged connection, if the temple needs maintenance, the temple extension can remain connected to the frame while the other parts of the temple can be removed from the temple extension for maintenance.

[0040] Fourthly, based on this, the frame can adopt a simpler design. As mentioned above, frame 1 does not require cables or optical mechanism attachments on the frame body 11, resulting in a simple design. That is, the frame body 11 can save materials as much as possible, mainly providing mounting areas for the headpiece, lens holder, nose pad holder, and lens. The mounting positions for the nose pad holder and lens holder can be reused, and the lens holder and headpiece can be integrated or reused. The headpiece can simultaneously connect the temples, clamp and fix the external structure of the lens coupling area, circumferentially support and fix the external structure of the lens coupling area, and install and fix the lens holder. This not only makes the design of each part simple, but also creates multiple limits between components, making assembly easy. Compared with existing related technologies, it also significantly increases the design freedom of the frame.

[0041] Fifthly, based on this, since the power supply unit, optical engine, motherboard unit, circuitry, and other electronic components are placed on the temples, the temples and frames can be easily assembled. The frame design can also be simplified and optimized. First, the same set of temples can be paired with different frame styles, or the same frame can be paired with different temple styles, thus quickly enriching the SKU (Stock Keeping Unit) of AR glasses products. Second, in the manufacturing or supply chain collaboration process, the temples can be manufactured, assembled, and tested by professional electronics manufacturers, while the main frame can be customized by established traditional eyewear manufacturers for different styles before final assembly. This effectively improves the level of division of labor and collaboration in the industry, and the convenience of manufacturing, assembly, and maintenance can also reduce costs. Third, from the perspective of the whole device, the overall solution helps to simplify and lighten the frame, and simplify the connection between the temples and the frame. Combined with the aforementioned technological effects, this helps AR glasses achieve an extremely lightweight and stylish product effect, thereby increasing the market penetration speed of AR glasses.

[0042] It should be noted that, in specific implementation, the temple (first temple 2) / frame 1 / AR glasses 100 of the above embodiment can be optimized or specified in at least one of the following ways: ① A bend is formed on the first temple body 21 (first temple 2), and the external dimensions of the first temple body 21 (second temple 2) from its head end to the bend generally transition smoothly from large to small in the extending direction, and / or, the external dimensions of the first temple body 21 from its tail end to the bend generally transition smoothly from large to small in the extending direction. This can further enhance the technical effect described in the second aspect above, and improve the wearing experience in terms of functional experience and visual effect. It should be noted that some technical solutions in related technologies are difficult to implement in this way due to the limitations of the overall structure, while the embodiments of this application, due to the use of a completely new shape, increase the design space of the temple, and therefore can be easily implemented.

[0043] ② To further achieve weight reduction, physical buttons and speakers can be removed from the temples; instead, a sound processing unit can be integrated into the temples to record and process the user's audio. To improve sound recording quality, such as... Figure 6 and Figure 13 As shown, a first sound hole 2122 and a second sound hole 204 can be opened at the top and bottom of the head area of ​​the temple; or an IMU (Inertial Measurement Unit) and a compass can be integrated into the temple for step counting, cervical spine angle detection, navigation direction determination, or basic head-motion interaction. In this way, the user's interaction with the AR glasses can still include at least touch interaction, voice interaction, and head-motion interaction.

[0044] ③ The outer side of the connection between the first temple extension 22 and the first temple body 21 can be designed as a smooth transition. This smooth transition can mean that, when viewed from the side by a third person after the user wears the glasses, the side of the first temple extension 22 is flush with the side of the first temple body 21. Alternatively, it can mean that the outer circumferential side of the cylindrical body 220 of the first temple extension 22 is flush with the outer circumferential side of the first temple body 21 adjacent to the connecting seat 2123. Adopting this solution further enhances the technical effect described in the second aspect and also helps to make it difficult to visually distinguish the temple from the first temple extension 22 and the first temple body 21.

[0045] ④ In order to improve the coupling incident fit between the optical engine 25 and the coupling area 41 of the first lens 4, and to meet the precise alignment requirements between the temple and the frame 1, such as Figure 4 , Figure 16 , Figure 20 and Figure 21As shown, a right first limiting hole 222 and a right second limiting hole 223 can be provided at the head end of the first temple 2, i.e., the head end of the first temple extension 22. Correspondingly, a right first limiting post 116a and a first post head limiting post 1221 are provided at the first end of the frame 1. Similarly, a left first limiting hole 322 and a left second limiting hole 323 can be provided at the head end of the second temple 3, i.e., the head end of the second temple extension 32. Correspondingly, a second limiting post 116b and a second post head limiting post (not shown in the figure) are provided at the second end of the frame 2. When both temples are fully open, the right first limiting post 116a and the first stake head limiting post 1221 at the right end of the frame 1 are respectively inserted into the right first limiting hole 222 and the right second limiting hole 223 on the first temple 21. The left first limiting post 116b and the second stake head limiting post at the left end of the frame 1 are respectively inserted into the left first limiting hole 322 and the left second limiting hole 323 on the second temple 31. This achieves precise alignment between the frame 1 and the two temples when the temples are open, ensuring the coupling and incident matching effect between the optical engine 25 on the first temple 1 and the first lens 4. Of course, the positioning method between the temples and the frame is not limited to this. In other embodiments, other types of component one can be provided on the temples, and other types of component two can be provided on the frame. These two components can achieve positioning matching when the temples are fully open. Furthermore, the aforementioned first pile head limiting post 1221 can also serve a reuse function. The first pile head limiting post 1221 can penetrate the first fixed support plate 122 of the first pile head component 12. One side of it is used to install in the right third mounting hole 117a to realize the installation of the first fixed support plate 122, and the other side can be used to match with the second limiting hole 223 of the first temple 2 to achieve precise alignment. Correspondingly, the aforementioned second pile head limiting post can also serve a reuse function. The second pile head limiting post can penetrate the first fixed support plate of the second pile head component 13. One side of it is used to install in the left third mounting hole 117b to realize the installation of the first fixed support plate, and the other side can be used to match with the second limiting hole 223 of the second temple 3 to achieve precise alignment.

[0046] ⑤ In order to improve the technical effect of the fourth aspect mentioned above and simplify the shape of the frame 1, a half-side first slot 112a can be provided on the lower side of the first part 111a of the frame body. The lower surface of the first slot 112a is flush with the surface of the first clamping and fixing area 113. The other half-side first slot 143 is provided on the first lens holder 14. A second slot 112b is provided on the lower side of the second part 111b of the frame body. The lower surface of the second slot 112b is flush with the surface of the second clamping and fixing area 113b. The other half-side second slot is provided on the second lens holder 15. This makes it easier to install and clamp the first lens 4 and the second lens 5.

[0047] ⑥ For example Figure 20 and Figure 24In order to simplify the shape of the frame 1 (frame body 11) while improving the fixing and limiting effect of the first post 12, a first limiting concave portion 118a can be provided on the right end of the frame body 1, for example on the first support fixing area. Correspondingly, a first limiting convex portion 1223 can be provided on the first post 12, for example on the first support fixing plate 122. In this way, when the first post 12 (first support fixing plate 122) is installed on the right end (first support fixing area) of the frame body 1, the first limiting concave portion 118a and the first limiting convex portion 1223 form a limiting match.

[0048] ⑦ In order to ensure a stable connection between the temples and the frame while further simplifying the frame structure and achieving an ultra-lightweight design, the applicant has explored, tested and verified that the external dimensions of the temple head can be further controlled. For example, the height of the first temple head (second temple head) can be controlled to be greater than or equal to 5mm and less than or equal to 10mm, and / or the height of the first temple head (second temple head) can be controlled to 18% to 22% of the height of the frame.

[0049] ⑧ After overall optimization and simplification of the design, and through the applicant's implementation and verification, the weight of the AR glasses in the above embodiments can be kept below 30g. In specific implementation, by strictly controlling the weight of each stage and making reasonable selections, the weight of the AR glasses can be further controlled to around 26g, i.e., 26±2g. Based on the foregoing and industry knowledge, this will further enhance the technical effects of the aforementioned aspects, significantly improve user acceptance of AR glasses, and improve the wearing experience and wearing time.

[0050] ⑨ In order to meet the requirements of lightweighting, further reduce the weight of the temples or the whole device, and improve the technical effects of the aforementioned aspects, the outer shells of the first temple 2 and the second temple 3 can be injection molded using low-density plastic particles (e.g., 0.83 low-density plastic particles); and / or, the frame body 1 can be injection molded using low-density plastic particles (e.g., 0.83 low-density plastic particles); and / or, the waveguide sheet can be made of resin waveguide sheet.

[0051] ⑩ The solution described in the above embodiments can also meet the performance or functional requirements such as battery life while being sufficiently lightweight. Specifically, the power supply unit 29 of the first temple 2 includes a battery with a capacity of 100mAh or greater. With proper selection, a battery with a capacity of 120mAh or more can also be used, such as a 120mAh steel-cased battery. In addition, while being sufficiently lightweight, the length of the first temple 2 and the second temple 3 can still be 135mm to 150mm, which can meet the wearing specifications of different people. Furthermore, the range of the outward angle of the AR glasses 100 can also cover various production needs. For example, the outward angle range is 93° to 100°, where the outward angle refers to the angle between the line connecting the two mounting points of the frame and the extension direction of the head area of ​​any temple.

[0052] It should be noted that in the above embodiments, the AR glasses are a single-optical-engine monocular display, and the other temple (second temple 3) is a non-AR glasses temple, meaning that the second temple 3 does not integrate optical engine components. Therefore, a certain amount of counterweight can be set on the second temple 3, or other functional modules can be integrated to optimize the weight distribution of the left and right temples. Integrating other functional modules can also bring new technical effects, giving the AR glasses 100 a new user experience. At the same time, it can also be concluded that in the above embodiments of this application, a single temple integrates most commonly used electronic components, while the other temple can be left free to flexibly combine different modules, which also improves the design freedom of the whole device from another perspective. Specifically, at least one of a sensor unit, a camera unit, a thermal imaging unit, and a depth camera unit can be further integrated on the second temple 3, and a power supply that provides power to the above units can also be integrated. For example, the sensor unit may include a Hall sensor to detect the opening angle of the temple relative to the frame, thus facilitating the control unit (e.g., motherboard unit 27) to determine whether the temple is fully open. The Hall sensor may also be integrated into the first temple 2. The sensing unit may include environmental sensors and combinations thereof, such as sensors for detecting air quality, humidity, and air pressure, making the AR glasses 100 suitable for outdoor adventures or industrial safety inspections. The sensing unit may include an ultrasonic ranging sensor array, making the AR glasses 100 suitable for assisted navigation for visually impaired or blind individuals. The camera unit may include a camera (e.g., wide-angle / telephoto), making the AR glasses suitable for on-site recording or real-time information overlay scenarios (e.g., maintenance guidance, remote teaching, violation recording, etc.). The thermal imaging unit may include a thermal imaging module, making the AR glasses suitable for nighttime search and rescue or electrical equipment temperature detection. The depth camera unit may include a depth camera, enabling the AR glasses to perform AR ranging, volume measurement, and 3D object scanning. In summary, by adopting the above solutions, the application scenarios of AR glasses are significantly expanded.

[0053] It should be noted that the foregoing embodiments of this application (referred to as the first embodiment for ease of description) provide a detachable connection method for the temple and the temple-frame, namely, the first temple 2 / second temple 3 and the frame 1 are connected by a simple hinge (i.e., through the hinge lug on the temple extension and the hinge lug on the post) to achieve a detachable connection between the temple and the frame. Combined with Figure 10 , Figure 11 , Figure 25 and Figure 26 As shown, another embodiment of this application (referred to as the second embodiment for ease of description) provides an alternative temple and a detachable connection method between the temple and the frame. The main differences between the second embodiment and the first embodiment are: a) the structure of the first temple extension 22 / second temple extension 32 has been adjusted; b) the first temple 2 / second temple 3 also includes a quick-release body 22' / quick-release body 32'. Considering the symmetrical arrangement of the two temples, the first temple is used for description here. As shown in the figure, in the second embodiment, the quick-release body 22' has an inner cavity and is through the front and back. The quick-release body 22' can be set at the head end of the first temple body 21. Optical mechanism 25, optical mechanism bracket 24 is located in the inner cavity of the quick-release body 22', and the first temple extension 22 is detachably fitted onto the outer side of the quick-release body 22'; in the second embodiment, the inner cavity sidewall of the first temple extension 22 can be a smooth sidewall, without the need for the first limiting protrusion 2203, the second limiting protrusion 2202, the assembly area of ​​the optical engine bracket 24, etc., as described in the first embodiment, but a limiting receiving part is provided on its sidewall, and the quick-release body 22' is provided with an elastic limiting part. During the process of the first temple extension 22 being fitted onto the quick-release body 22', the elastic limiting part is pressed and moves until it is located in the limiting receiving part, thereby realizing the detachable installation of the first temple extension 22 on the quick-release body 22'.

[0054] In specific implementation, as shown in the figure, the quick-release body 22' includes a cylindrical body 220', the inner cavity of the cylindrical body 220' is through, forming a first opening 224' and a second opening 225'. The first opening 224' is a partially open structure, the end of the cylindrical body 220' where the second opening 225' is located is the tail end, and the end of the cylindrical body 220' where the first opening 224' is located is the head end; the inner wall of the cylindrical body 220' can be provided with circumferentially spaced... The cylindrical body 220' has a first limiting protrusion 2203' and a second limiting protrusion 2202' extending in roughly the same direction. The first limiting protrusion 2203' can match the first limiting groove 2127 on the head end connector 2124 of the first temple 2, and the second limiting protrusion 2202' can match the second limiting groove 2129 on the connector 2124. The outer side wall of the head end of the cylindrical body 220' can be provided at the position surrounding the first opening 224'. The outer part 2201' is used for the installation of the protective light-transmitting sheet 23; the inner sidewall of the head end of the cylindrical body 220' can be provided with an assembly area for the optical engine bracket 24 around the first opening 224'; the inner sidewall of the head end of the cylindrical body 220' can be provided with a support mounting area 2204' around the first opening 224', and the support mounting area 2204' is provided with a first positioning limiting groove 2205' and a second positioning limiting groove 2206' at intervals in the circumferential direction. The first positioning limiting groove 2205' matches the first positioning limiting part 2431 of the support 243 on the optical engine bracket 24, and the second positioning limiting groove 2206' matches the second positioning limiting part 2432 of the support 243 on the optical engine bracket 24; the assembly relationship and sequence of the cylindrical body 220' with the connector 2124, the optical engine 25, and the optical engine bracket 24 can be referred to the relevant description of the first temple extension 22 in the first embodiment, and will not be repeated here. Therefore, it can be seen that the quick-release body 22' in the second embodiment adopts an internal structure and head end structure similar to the first temple extension 22 in the first embodiment. In addition, as... Figure 25As shown, the side wall of the cylindrical body 220' of the quick-release body 22' is provided with a U-shaped groove 221' and an elastic plate 222' formed therefrom. The elastic plate 222' is provided with a limiting bead 229' as the aforementioned elastic limiting part. Correspondingly, the limiting receiving part of the first temple extension 22 is a limiting bead hole 229 that matches the limiting bead 229'. In terms of assembly sequence, after the quick-release body 22' is assembled with the connecting seat 2123 at the head end of the first temple body 21, the first temple extension 22 can be slowly moved around the outer periphery of the quick-release body 22'. At this time, the limiting bead 229' of the quick-release body 22' is compressed and has a certain elasticity due to the elastic plate 222'. Therefore, it can move forward tightly against the inner side wall of the first temple extension 22 under pressure. When it moves to the position of the limiting bead hole 229, it springs into the limiting bead hole 229, thereby realizing the installation limiting of the quick-release body 22' and the first temple extension 22. After adopting the above solution, in addition to the primary detachable connection between the temple and frame, a secondary detachable connection is added between the quick-release body 22' and the first temple extension 22. This will make it more convenient to assemble, disassemble, and maintain the temple. For example, when the temple needs maintenance, it is not necessary to disassemble the hinge between the first temple extension 22 and the frame 1. Instead, the other parts of the temple can be detached from the first temple extension 22 for maintenance via the quick-release body 22'. In the above specific embodiment, a limiting bead hole is used as a limiting receiving part on the first temple extension 22, and a limiting bead provided on the elastic plate 222' is used as an elastic limiting part on the quick-release body 22'. However, in other specific embodiments, it is not limited to this, and other methods that can achieve detachable installation and limiting of the quick-release body 22' and the first temple extension 22 can also be used. In addition, the protective light-transmitting sheet 23 can also continue to be provided on the first temple extension 22.

[0055] It should be noted that in the temple solutions provided by the above-mentioned various embodiments and specific implementations of this application, the temple preferably adopts the partitioned arrangement of each electronic component and the partitioned change of the temple body shape to achieve the aforementioned technical effects. However, in other embodiments, it is not limited to this preferred solution. For example, it may only adopt the partitioned arrangement of each electronic component or only adopt the partitioned change of the temple body shape size, which can also achieve the corresponding technical effects.

[0056] It should be noted that in the temple solutions provided by the various embodiments and specific implementations of this application, the temple body can be formed by a first housing and a second housing that is fastened and connected to the first housing. However, in other embodiments, it is not limited to this and other temple body solutions with internal cavities and suitable for assembly can also be used.

[0057] It should be noted that the optical mechanism settings of the AR glasses temples proposed in the various embodiments and specific implementations of this application can be adopted. Figure 18The structure of the optical engine bracket 24 shown is used to install the optical engine 25. The optical engine bracket 24 and the first temple extension 22 (or quick-release body 22') and the first temple extension 22 (or quick-release body 22') and the connecting seat 2123 are assembled using the aforementioned corresponding structures. However, in other embodiments, it is not limited to this. For example, the optical engine bracket and its installation can take other forms. For example, the first end of the optical engine bracket 24 and the head end of the temple body can take other structures that can form a rotation limit. The second end of the optical engine bracket 24 and the inner wall of the first temple extension 22 can take other structures that can form a positioning match and rotation limit. For example, the protrusion and groove structure between the two parts can be replaced. In addition, the setting of the first temple extension 22 (quick-release body 22') at the head end of the temple body can also be adjusted, as long as the installation and positioning of the two can be achieved.

[0058] It should be noted that the AR glasses frames provided in the above-described embodiments and specific implementations of this application, including the frame body 11 and the stake head, adopt the following...

It is understood that different forms can be used to clamp, fix, and circumferentially support the structure outside the lens coupling area. For example, the concave and convex portions between the two components can be interchanged. Furthermore, the pile head can be positioned at different locations on the pile head component in different situations, such as on a support fixing plate. Additionally, the pile head component can also achieve only partial installation reuse.

[0059] It should be noted that in the various embodiments and specific implementations of this application, the frame and temple are positioned and matched by limiting posts and limiting post holes. However, in other embodiments, other positioning and matching methods can also be used, such as replacing the setting positions of the limiting posts and limiting post holes.

[0060] It should be noted that in the various embodiments and specific implementations described above in this application, the AR glasses 100 are monocular displays on the right side of a single-optical-engine. However, in other embodiments of this application, this is not a limitation. For example, it can also be a monocular display on the left side of a single-optical-engine, i.e., the left temple adopts the aforementioned first temple 1, while the right temple adopts the aforementioned second temple 2. Furthermore, in other embodiments, the AR glasses can also be binocular displays with a dual-optical-engine, i.e., both lenses are waveguides, and both temples adopt the first temple 2 (but the shape of the two temples is symmetrical).
