Description

Augmented reality glasses Technical Field

[0001] The present invention relates to the field of optical display technology, and in particular to augmented reality glasses. Background Art

[0002] Augmented reality (AR) is a technology that merges virtual information with the real world. It uses computer technology to simulate physical information, which is difficult to experience in the real world, and effectively applies it to the real world. This process is perceived by human senses, creating a sensory experience beyond reality. The real environment and virtual objects overlap, allowing them to exist simultaneously in the same screen and space.

[0003] Augmented reality technology not only effectively displays real-world content, but also enables the display of virtual information, with these detailed contents complementing and superimposing each other. In visual augmented reality, users need to use a head-mounted display to overlap the real world with computer graphics, allowing them to fully see the real world around them.

[0004] The application and rapid development of AR technology have expanded from its original fields to many new fields, such as urban planning and virtual simulation teaching, which has changed the way consumers, businesses and the digital world interact to a certain extent.

[0005] Currently, there are a variety of augmented reality headsets on the market, generally falling into two categories: AR helmets and AR glasses. AR glasses offer advantages due to their lightweight and portable design. However, AR glasses are typically monolithic, with the frames forming a fixed, integral unit through both exterior and structural design, making them inconvenient to carry.

[0006] On the other hand, most augmented reality head-mounted products also include multiple functional modules, control modules, etc. Most components are distributed near the lenses, and the overall center of gravity is at the front. In order to balance the center of gravity, counterweights are usually set at the rear end of the head-mounted product, which increases the overall weight of the product and results in a poor user experience when wearing it for a long time.

[0007] Summary of the Invention

[0008] In response to the above problems, the present invention provides an augmented reality glasses, which reduces the overall length of the augmented reality glasses when not in use by separating some components of the projection assembly into different components of the frame, arranging the light source module on the temples of the frame, and arranging the projection lens on the mounting frame of the frame.

[0009] One object of the present invention is to provide augmented reality glasses, wherein a portion of a projection assembly arranged on a mounting frame portion of the temple is a first projection portion, and another portion arranged on the frame is a second projection portion. By making the temple foldable or detachable relative to the mounting frame portion, the first projection portion can be movably connected relative to the second projection portion, thereby reducing the lengthwise size of the augmented reality glasses when in a stored state.

[0010] One object of the present invention is to provide augmented reality glasses, wherein a mounting frame extends from a frame border away from a crossbeam in a direction perpendicular to a display assembly to form an extension portion, the extension portion being hollow inside and used for mounting a second projection portion, that is, the frame and the extension portion are integrally formed, and the display assembly and the second projection portion are mounted using the integrally formed frame and extension portion as a mounting reference surface, thereby enhancing the overall rigidity of the mounting frame while increasing the assembly accuracy of the projection display system and simplifying the assembly process.

[0018] One object of the present invention is to provide augmented reality glasses, in which the connecting component is arranged near the inner side of the head to reserve external space for the mounting portion and the extension portion, thereby meeting the space requirements for the installation of the projection component.

[0019] One object of the present invention is to provide augmented reality glasses, in which a connecting assembly includes a limiter, which is embedded and fixed with a first connecting portion through the limiter, and is rotatable with a second connecting portion through the connecting member, to ensure that when the temples and the mounting frame are in an unfolded state, the first projection portion and the second projection portion form a complete optical path, and the coupling deviation or jitter of the first projection portion and the second projection portion will not be caused by the user's head movement.

[0020] One object of the present invention is to provide augmented reality glasses. When in a stored state, the temples are folded, the first projection portion and the second projection portion are staggered, and the circuit of the first projection portion is disconnected. When in an unfolded state, the first projection portion and the second projection portion are in a straight line, and the circuit of the first projection portion is turned on. Through this design, the opening and closing of the first projection portion can be controlled.

[0021] One object of the present invention is to provide an augmented reality glasses, in which the temples are detachable from the mounting frame, and the temples change between a coupled state and a disengaged state, so that the first projection portion can be detached or assembled relative to the second projection portion, thereby reducing the overall volume occupied when stored and facilitating portability. In addition, different temples 12 can be selected to meet the wearing size requirements of different users.

[0022] One object of the present invention is to provide an augmented reality pair of glasses, wherein the temples are provided with buckles and the extension portions are provided with slots, which are connected by snapping, making them easy to install and disassemble.

[0023] One object of the present invention is to provide augmented reality glasses, in which slots or buckles are arranged at four corners or edges to achieve a reasonable spatial layout.

[0024] One object of the present invention is to provide augmented reality glasses.

[0026] One object of the present invention is to provide augmented reality glasses. When the light source module is a three-color light source, two monochromatic light sources are arranged on the outside away from the user's head. On the one hand, this satisfies the heat dissipation of the light source module, and on the other hand, it prevents the light source module from overheating and scalding the user's head when working.

[0027] One object of the present invention is to provide an augmented reality glasses, in which two monochromatic light sources are arranged on the same side, reducing the size of the light source module in the width direction, thereby reducing the size of the first projection part in the width direction and reducing the width of the temples.

[0029] One object of the present invention is to provide augmented reality glasses, wherein a display assembly includes a main area and an extension area extending from the main area away from the crossbeam. By extending only the extension area to a size close to that of the coupling area, the overall size and weight of the display assembly can be reduced, thereby avoiding the display assembly being too large, which would result in the augmented reality glasses being larger in size.

[0030] Other advantages and features of the present invention will become more apparent from the following detailed description and will be realized by means of the instrumentalities and combinations particularly pointed out in the appended claims.

[0056] Before describing in detail any embodiment of the present invention, it should be understood that the present invention is not limited in its application to the construction and arrangement details of the components set forth in the following description or illustrated in the following figures. The present invention is capable of other embodiments and can be practiced or carried out in various ways. In addition, it should be understood that the words and terms used herein are for descriptive purposes and should not be considered restrictive.

Unless otherwise specified or limited, the terms "mount," "connect," "support," and "couple" and variations thereof are used broadly and cover both direct and indirect mounting, connection, support, and coupling. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings.

[0057] Furthermore, on the first hand, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore the above terms cannot be understood as limitations on the present invention; on the second hand, the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" cannot be understood as a limitation on the quantity.

[0058] AR technology can use either a waveguide solution (i.e., a light source, projection lens, and waveguide) or a traditional birdbath solution. The traditional birdbath solution is unpopular with consumers due to its large size, difficulty in further improving the field of view, and relatively poor user experience. In contrast, the waveguide solution primarily places a waveguide in front of the user's eyes, resulting in a smaller AR display and a better user experience. Consequently, AR displays using waveguides are gaining increasing acceptance.

[0059] Compared to AR headsets, AR glasses are smaller in size. Traditional AR glasses consist of an optomechanical assembly and a waveguide lens. The optomechanical assembly is used to generate images. The waveguide lens has an incoupling zone and an outcoupling zone. The image generated by the optomechanical assembly enters the waveguide lens through the incoupling zone, is then transmitted to the outcoupling zone after total internal reflection from the waveguide lens, and is emitted from the outcoupling zone to the user's eye.

[0060] However, for this type of AR glasses architecture, light emitted by the optomechanical assembly enters the waveguide lens's coupling-in area and enters the user's eyes through the waveguide lens's coupling-out area. Typically, the optomechanical assembly is located on the side of the frame, with a total volume of 2 to 3cc or more, for example, 16 x 15 x 10mm. This causes the AR glasses architecture to occupy a large space on both sides of the user's eyes, further increasing the overall size of the AR glasses architecture and affecting the AR device experience. Furthermore, due to the large size of this AR glasses architecture, it does not conform to the user's conventional perception of head space, making it prone to bumps and collisions during use, resulting in a poor user experience.

[0061] In order to solve the above problems, the present application provides an augmented reality glasses, which reduces the overall length size of the augmented reality glasses in the non-working state by separating some components of the projection assembly into different components of the frame, setting the light source module on the temples of the frame, and setting the projection lens on the mounting frame of the glasses. By designing some components of the frame to be foldable or detachable, the glasses can be reduced in length when not in use.

[0062] As shown in Figure 1, the present application provides an augmented reality glasses 1, comprising a frame 10 and at least one projection display system 20, at least one data processing module 30 and at least one power module 40 arranged on the frame 10. The projection display system 20 is connected to the data processing module 30 and the power module 40, and is used to receive the signal of the data processing module 30 to realize projection imaging. The power module 40 provides power to the projection display system 20 and the data processing module 30. The power module 40 can be an independent battery module built into the augmented reality glasses 1, or it can be a power connection module for external connection to an external power supply. In some optional embodiments, the augmented reality glasses 1 further include at least one signal transmission module 50, which is used to realize information transmission with at least one external device.

[0063] The projection display system 20 further includes at least one projection assembly 21 and at least one display assembly 22. The projection assembly 21 is equipped with an optical imaging element, which forms a distant virtual image through the optical imaging element and projects it into the user's eyes through the display assembly 22. When implementing the perspective function, the augmented reality glasses 1 allow the user to see both the real external world and virtual information. Through layering, the virtual information and the real scene are integrated and complement each other.

[0064] Furthermore, the frame 10 includes a mounting frame 11 and two temples 12 connected to both sides of the mounting frame 11. The mounting frame 11 can be mounted on the nose wings of the user, and the temples 12 are used to be mounted on the ears of the user to enable the augmented reality glasses 1 to be worn. The two temples 12 can be movably connected to the mounting frame 11 and can be foldable or detachable.

[0065] For the convenience of explanation, the side of the augmented reality glasses 1 facing the human face when worn is defined as the back side, the side away from the human face is defined as the front side, and the front-to-back direction is the length direction of the augmented reality glasses 1. Correspondingly, the two temples are respectively arranged on the left and right sides of the mounting frame 11, the left-right direction is the width direction of the augmented reality glasses 1, and the up-down direction is the height direction of the augmented reality glasses 1.

[0066] At least a portion of the projection display system 20 is disposed on the mounting frame 11, and another portion of the projection display system 20 is disposed on the temple 12. Furthermore, the display assembly 22 is disposed on the mounting frame 11 of the frame 10, a portion of the projection assembly 21 is disposed on the mounting frame 11, and another portion is disposed on the temple 12. The portion of the projection assembly 21 disposed on the temple 12 is defined as a first projection portion, and the portion of the projection assembly 21 disposed on the mounting frame 11 is defined as a second projection portion. The two temples 12 are foldable or detachable relative to the mounting frame 11, that is, the first projection portion is movably connected relative to the second projection portion.

[0067] The mounting frame 11 includes a frame 111 and an extension portion 112 arranged on both sides of the frame 111. The frame 111 is composed of two frame bodies 1111 with two through holes 1112. The through holes 1112 are provided in each of the frame bodies 1111 and the two frame bodies 1111 are connected by a crossbeam 1113. The display assembly 22 is installed in the through hole 1112. The extension portion 112 is formed by extending from the frame 111 away from the crossbeam 1113 in a direction perpendicular to the display assembly 22, that is, the extension portion 112 protrudes from the frame 111 and extends in the rear direction. The extension portion 112 is hollow inside and has an optical machine installation area 1121. The second projection portion is arranged in the optical machine installation area 1121. The frame 111 and the extension portion 112 are integrally formed to simplify the molding process of the mounting frame 11 and increase the overall strength and rigidity of the mounting frame 11. The material of the mounting frame 11 includes, but is not limited to, metal, plastic, resin, etc. The display assembly 22 and the second projection unit are mounted using the integrally formed frame 111 and extension 112 as the mounting reference surface. This enhances the overall rigidity of the mounting frame 11, increases the assembly accuracy between the internal components of the projection display system 2, and simplifies the assembly process.

[0068] The temple 12 extends entirely along the extension direction of the extension portion 112, that is, along its length. It includes a mounting portion 121, a wearing portion 122 extending rearward from the mounting portion 121, and a cover plate 123. The mounting portion 121 is located proximal to the extension portion 112 of the mounting frame 11, while the wearing portion 122 is distal thereto. The mounting portion 121 and the wearing portion 122 are provided with a receiving cavity, wherein the first projection portion and other functional components are disposed. The first projection portion is disposed within the mounting portion 121, proximal to the extension portion 112 of the mounting frame 11. The wearing portion 122 can be mounted on the user's ear, enabling the augmented reality glasses 1 to be worn. The cover plate 123 seals the mounting portion 121 and the wearing portion 122. This design allows the mounting portion 121 to be sealed after each component is installed within the receiving cavity of the mounting portion 121, making the assembly process simple and efficient. The mounting portion 121 and the wearing portion 122 may be integrally formed to form the temple 12 together with the cover plate 123 .

[0069] When the augmented reality glasses 1 are worn, the inner side is closer to the user's head, and the outer side is farther away from the user's head. The mounting portion 121 of the temple 12 is designed to protrude outward. This allows the mounting portion 121 to accommodate the larger first projection portion and, at the same time, to fit the width of the mounting portion 121 with the extension portion 112 of the mounting frame 11. Furthermore, the mounting portion 121 does not occupy the gap between the temple 12 and the user's head, leaving ample room for heat dissipation.

[0070] The second projection portion is disposed on the extension portion 112 of the mounting frame portion 11 , and the first projection portion is disposed on the mounting portion 121 of the temple 12 . The first projection portion and the second projection portion constitute a complete projection assembly 21 for realizing projection imaging.

[0071] Specifically, the projection assembly 21 includes a light source module 211, at least one light deflection element 212, a display module 213, and a projection lens 214. The light source module 211 provides outgoing light, the light deflection element 212 changes the light's optical path, the display module 213 forms a corresponding image, and the projection lens 214 directs the light into the display assembly 22. The various components of the projection assembly 211 form a complete projection optical path. Light emitted from the light source module 211 passes through the at least one light deflection element 212, is imaged by the display module 213, and then projects a corresponding virtual image through the projection lens 214. The projection lens 214 is positioned closest to the display assembly 22, with its optical axis perpendicular to the display assembly 22. In some embodiments, the light source module 211 is positioned parallel to the optical axis of the projection lens 214, so that the optical axis of the light emitted from the light source module 211 is parallel to and centered on the optical axis of the projection lens 214.

[0072] In some optional embodiments, as shown in FIG10 , the light source module 211 of the projection assembly 21 is a first projection portion, disposed within the mounting portion 121 of the temple 12. The light deflection element 212, display module 213, and projection lens 214 of the projection assembly 21 are a second projection portion, disposed within the cavity of the extension portion 112. When the optical axis of the outgoing light from the first projection portion is aligned with the center of the incoming light from the second projection portion, the first and second projection portions form a complete projection optical path, achieving projection imaging.

[0073] In other optional embodiments, as shown in Figure 10, the light source module 211, the light-transmitting element 212, and the display module 213 of the projection assembly 21 constitute a first projection unit, which is disposed within the mounting portion 121 of the temple 12. The projection lens 214 of the projection assembly 21 constitutes a second projection unit, which is disposed within the extension portion 112. When the optical axis of the light emitted by the first projection unit is aligned with the center of light incident on the second projection unit, the first and second projection units form a complete projection optical path for achieving projection imaging. Simultaneously, by shifting some components rearward, the center of gravity of the augmented reality glasses 1 as a whole is shifted rearward, thereby improving wearing comfort for the user.

[0074] The first projection portion of the projection assembly 211 is arranged in the mounting portion 121 of the temple 12, and the second projection portion is arranged in the extension portion 112 of the mounting frame portion 11. As the temple 12 is foldable or detachable relative to the extension portion 112 of the mounting frame portion 11, the second projection portion is foldable or detachable relative to the first projection portion.

[0075] As shown in Figures 1-5, the temple 12 can be movably connected relative to the mounting frame 11. The temple 12 is connected to the mounting frame 11 of the frame 10 by means of a hinge or a rotating shaft, so that the temple 12 can rotate relative to the mounting frame 11. The temple 12 is rotatably connected to the mounting frame 11 through a connecting assembly 13, so that the temple 12 can be folded relative to the mounting frame 11 between an unfolded position and a folded position, and the first projection portion can rotate relative to the second projection portion.

[0076] In this way, when the augmented reality glasses 1 are not in use, the two temples 12 can be folded up and moved closer to the mounting frame 11, thereby reducing the overall volume of the frame 10 and making it easier to carry. At the same time, the temples 12 can be movably connected to the mounting frame 11, making the product form more similar to ordinary glasses. The temples 12 fit the head more lightly and comfortably, providing a better wearing experience. The weight, volume, and clamping force are close to those of ordinary glasses, making them suitable for a wider range of usage scenarios, such as sports and fitness.

[0077] The mounting frame 11 and the temple 12 are movably connected via the connecting assembly 13. As shown in Figure 3, the connecting assembly 13 includes a first connecting portion 131, a second connecting portion 132, and a connecting member 133. The first connecting portion 131, the second connecting portion 132, and the connecting member 133 are movably connected. The first connecting portion 131, the second connecting portion 132, and the connecting member 133 are rigid structures, i.e., highly resistant to deformation, and can be made of high-strength metal. The connecting member 133 can be hinged or a rotating shaft. The angle between the first connecting portion 131 and the second connecting portion 132 can be adjusted. The first connecting portion 131 is located on the mounting portion 121 of the temple 12, and the second connecting portion 132 is located on the extending portion 112 of the mounting frame 11. The connecting member 133 allows the temple 12 to be positioned relative to the extending portion 112 of the mounting frame 11. In some embodiments, the first connecting portion 131 can be integrally formed with the temple 12. The temple 12 can be rotated relative to the second connecting portion 132 via the connecting member 133, allowing the angle between the temple 12 and the extension portion 112 to change, and the first projection portion to rotate relative to the second projection portion. In some embodiments, because the projection assembly 21 occupies a considerable amount of space, the width of the extension portion 112 and the mounting portion 121 are also relatively large. The connecting assembly 13 is positioned on the inner side near the user's head, with the first connecting portion 131 positioned on the inner side of the temple 12 and the second connecting portion 132 positioned on the inner side of the extension portion 112 to reserve external space for the mounting portion 121 and the extension portion 112, thereby meeting the space requirements for installing the projection assembly 21. When folded, the temple 12 bends inwardly toward the frame 111, with the optical axis of the light emitted from the first projection portion offset from the center of light incident on the second projection portion. In the unfolded state, the temples 12 are opposite to the frame 111 , and the optical axis of the light emitted from the first projection portion and the light incident center of the second projection portion are in a straight line.

[0078] A first optical path hole 1212 is formed on the first end surface 1211 of the temple 12, near the extension portion 112. A second optical path hole 1123 is formed on the second end surface 1122 of the extension portion 112 of the mounting frame 11, near the temple 12. The first optical path hole 1212 of the temple 12 is located outside the first connecting portion 131, away from the user's head. The second optical path hole 1123 of the extension portion 112 is located outside the second connecting portion 132, away from the user's head. When folded, the first optical path hole 1212 and the second optical path hole 1123 are offset, and the components of the projection assembly 21 are not in operation. When in the expanded state, the first optical path through hole 1212 and the second optical path through hole 1123 are coaxially arranged, and the optical axis of the light emitted from the first projection part and the light incident center of the second projection part are in a straight line, so that all the light emitted by the light source module 211 can pass through the first optical path through hole 1212 and the second optical path through hole 1123 to reach the second projection part, enter the projection lens 214 of the projection component 21, and enter the coupling area of ​​the display component 22 through the projection lens 214.

[0079] In some embodiments, as shown in Figures 1 to 5, the first connecting portion 131 can be connected to the second connecting portion 132 in a mutually rotatable manner via the connecting member 133. The first connecting portion 131 and the second connecting portion 132 have coaxially arranged through holes, and the connecting member 133 includes at least one cylindrical structure. The first connecting member 133 is inserted into the through holes of the first connecting portion 131 and the second connecting portion 132. The connecting member 133 provides an axis of rotation for the first connecting portion 131 and the second connecting portion 132, and the first connecting portion 131 or the second connecting portion 132 rotates relative to the other connecting portion around the axis. The first connecting portion 131 includes at least one first connecting post 1311 and a first through hole 13111 coaxial with the first connecting post 1311. The second connecting portion includes at least one second connecting post 1321 and a second through hole 13211 coaxial with the second connecting post 1321. The second connecting post 1321 includes two second connecting posts 1321 spaced apart from each other. The first connecting post 1311 of the first connecting portion 131 is disposed in the gap between the two second connecting posts 1321 of the second connecting portion 132, such that the first through hole 13111 and the second through hole 13211 are coaxial. The first connecting member 133 is inserted into each through hole of the first connecting portion 131 and the second connecting portion 132, such that the connecting member 133 is fixed to the second connecting portion 132, and the first connecting portion 132 is rotatable relative to the connecting member 133. The first connecting portion 131 is integrally formed with the mounting portion 121 of the temple 12, and the second connecting portion 132 is fixedly arranged on the extending portion 112 of the mounting frame portion 11. The first connecting portion 131 rotates relative to the second connecting portion 132 around the axis of the connecting member 133, and the temple 12 can rotate relative to the extending portion 112 of the mounting frame portion 11.

[0080] In some embodiments, as shown in Figures 4A and 4B, the second connecting portion 132 may further include a base 1322 and a fixing frame 1323. The base 1322 is fixedly connected to the extension portion 112 of the mounting frame 11, and is fixedly connected to the extension portion 112 to form an annular structure with a receiving cavity. The fixing frame 1323 secures the second projected portion to the base 1322 along the length direction, thereby securing the second projected portion to the mounting frame 11. The base 1322 also includes a fixed end 13221 and an extended end 13222. The fixed end 13221 extends along the length direction, and the extended end 13222 extends along the width direction. The fixing frame 1322 secures the second projected portion to the fixed end 13221 of the base 1321. One side of the extended end 13222 is in contact with and fixed to the second end surface 1122 of the extension portion 112. When in the unfolded state, the other side is disposed opposite the first end surface 1211 of the mounting portion 121 of the temple 12. The extension end portion 13212 includes a light path hole 13223, which is coaxially arranged with the second light path hole 1123, so that the light projected by the first projection portion can pass through the light path hole 13223, enter the second light path hole 1123 of the extension portion 112, and enter the second projection portion.

[0081] Furthermore, the connecting assembly 13 may also include a stopper 134. The stopper 134 includes a connecting body 1341 and a stopper post 1342 protruding toward the extension portion 112. The stopper 134 is embedded and fixed to the first connecting portion 131, and the first connecting portion 131 is fixed to the mounting portion 121 of the temple 12, thereby fixing the stopper 134 to the mounting portion 121 of the temple 12. The first connecting portion 131 is provided with a groove adapted to the stopper 134. When the stopper 134 is installed in the first connecting portion 131, the connecting body 1341 is embedded in the gap between the two first connecting posts 1311. The third through hole 13421 of the stopper post 1342 is coaxially arranged with the first through hole 1311. The stopper 134 is rotatably connected to the second connecting portion 132 via the connecting member 133. The limiter 134 is a stable rotating shaft structure, which ensures that when the temple 12 and the mounting frame 11 are in the unfolded state, the first projection part and the second projection part form a complete optical path, and the coupling deviation or jitter of the first projection part and the second projection part will not be caused by the user's head movement.

[0082] Specifically, when the augmented reality glasses 1 are worn and used normally, the augmented reality glasses 1 are in an unfolded state, and the two temples 12 are opposite to each other relative to the mounting frame 11. The optical axis of the outgoing light of the first projection portion in the temple 12 and the incident light center of the second projection portion installed on the extension portion 112 are on a straight line, and the temple 12 is parallel to the extension direction of the extension portion 112. The second end face 1122 of the extension portion 112 is parallel to the first end face 1211 of the mounting portion 121, and the angle α1 between the two end faces is 0°. The first optical path through hole 1212 of the temple 12 is coaxially arranged with the second optical path through hole 1123 of the extension portion 112. The first projection portion located at the mounting portion 121 of the temple 12 and the second projection portion located at the extension portion 112 are connected by the circuit, and the light source module 211 can be powered on to illuminate the outgoing light, and the display module 211 is in a working state. The optical axis of the light emitted from the first projection portion is aligned with the light incident center of the second projection portion, i.e., the light path is straightened. The light emitted from the first projection portion passes through the first light path through hole 1212 and the second light path through hole 1123 to reach the second projection portion, and the light emitted after passing through the projection lens 214 is coupled into the display assembly 22.

[0083] When the augmented reality glasses 1 are in the storage state, the augmented reality glasses 1 are in the folded state, the temples 12 are bent inward and arranged close to the frame 111, and the first projection portion and the second projection portion are staggered. The second end face 1122 of the extension portion 112 and the first end face 121 of the mounting portion 121 form an angle α2, and α2 can be between 60° and 120°. At this time, the first optical path through hole 1212 of the temple 12 and the second optical path through hole 1123 of the extension portion 112 are staggered. The first projection portion circuit located at the mounting portion 121 of the temple 12 is disconnected, and the light source module 211 is not powered, that is, it is in a non-working state.

[0084] When the augmented reality glasses 1 are transformed from a folded state to an unfolded state, i.e., when they are intended for normal wear and use, the angle between the second end surface 1122 of the extension portion 112 and the first end surface 1211 of the mounting portion 121 changes from α2 to α1, causing the position of the temple 12 relative to the extension portion 112 of the mounting frame 11 to change, and the position of the first projection portion relative to the second projection portion to change. When the angle between the first end surface 1121 and the second end surface 1122 reaches α1, i.e., when the two end surfaces are parallel, the circuit of the first projection portion is turned on, and the light source module 211 can be turned from an unpowered state to an energized state, i.e., the light source module 211 is illuminated and emits light.

[0085] To detect the positional relationship between the first and second projections, the circuit states of the first and second projections change accordingly when the relative position of the first projection relative to the second projection changes. Specifically, when the first and second projections are aligned, the circuit between the first and second projections is connected; when the first and second projections are offset, the circuit is disconnected. The frame 10 is provided with a sensing device for detecting the position of the first and second projections relative to each other. The sensing device can be a pressure sensor, a laser sensor, or the like, and can be located within the connection assembly 13. The sensing device is connected to a control unit and outputs different signals in different states. When the first and second projections are offset, i.e., in the folded state, the sensing device outputs a corresponding signal, causing the control unit to close the circuit and disable the first and second projections. When the first and second projections are aligned, i.e., in the unfolded state, the sensing device outputs a corresponding signal. Based on the signal output by the sensing device, the control unit controls the circuit, connecting the first and second projections and activating them. In some embodiments, in addition, a switch device can be provided. By opening the switch device, the switch device is connected to the circuit of the light source module 211 or the display module 213. When the user needs it, the light source module 211 is turned on to illuminate the projection or the imaging of the display module 213, so as to manually control the working time of the projection component 21, thereby saving energy consumption.

[0086] Furthermore, the temple 12 includes a first temple 12-L and a second temple 12-R, wherein the first temple 12-L is located on the left side of the mounting frame 11, and the second temple 12-R is located on the right side of the mounting frame 11, and the first temple 12-L and the second temple 12-R are foldable relative to the mounting frame 11.

[0087] Correspondingly, the mounting frame 11 includes a frame 111 and an extension 112. The two through holes 1112 of the frame 111 of the mounting frame 11 include a first through hole 1112-L and a second through hole 1112-R, wherein the first through hole 1112-L is located on the left side of the frame 1111, and the second through hole 1112-R is located on the right side of the frame 1111. The extension 112 includes a first extension 112-L and a second extension 112-R, wherein the first extension 112-L is formed perpendicularly to the frame 1111 from the left side, and the second extension 112-R is formed perpendicularly to the frame 1111 from the right side. The display assembly 22 includes a first display assembly 22-L and a second display assembly 22-R. The first display assembly 22-L is installed in the first through hole 1112-L, and the second display assembly 22-R is installed in the second through hole 1112-R. When the augmented reality glasses 1 are in use, the first through hole 1112-L corresponds to the user's left eye field of view, and the second through hole 1112-R corresponds to the user's right eye field of view, so that the light coupled out of the display assembly 22 can enter the user's eyes. The connecting assembly 13 includes a first connecting assembly 13-L and a second connecting assembly 13-R. The first temple 12-L is rotatably connected to the first extension portion 112-L through the first connecting assembly 13-L, and the second temple 12-R is rotatably connected to the second extension portion 112-R through the second connecting member 13-R.

[0088] In some embodiments, the first temple 12-L and the second temple 12-R are respectively rotated relative to the mounting frame 11 by a predetermined angle via the first connecting member 13-L and the second connecting member 13-R, and the first temple 12-L and the second temple 12-R are placed adjacent to each other, and the AR glasses device is in a folded state. In another embodiment, the first temple 12-L is rotated relative to the first extension 112-L by a first angle, and the second temple 12-R is rotated relative to the second extension 112-R by a second angle, the first angle being less than the second angle, and the first temple 12-L and the second temple 12-R can be adjacent to each other, with the second temple 12-R being located near the mounting frame 11. In another embodiment, the first temple 12-L is rotated by a first angle relative to the first extension portion 112-L, and the second temple 12-R is rotated by a second angle relative to the second extension portion 112-R, the first angle being greater than the second angle, the first temple 12-L and the second temple 12-R may be adjacent to each other, and the first temple 12-L is located near the mounting frame portion 11. The location of the first temple 12-L or the second temple 12-R near the mounting frame portion 11 does not affect the determination of whether the AR glasses are folded.

[0089] The projection assembly 21 can be two, namely a first projection assembly 21-L and a second projection assembly 21-R, which are separately disposed within the frame 10. The sensing device for detecting the position of the first projection portion relative to the second projection portion can be one, disposed only on one side, to detect the position of the first projection portion relative to the second projection portion on that side. That is, the first projection assembly 21-L and the second projection assembly 21-R only need to be powered on when the temple 12 on that side is in an unfolded state relative to the extension portion 112. The sensing device can also be two, each measuring the positional relationship between the left and right sides, the first temple 12-L relative to the first extension portion 112-L, and the second temple 12-R relative to the second extension portion 112-R, and only when both temples 12 are in an unfolded state.

[0090] As shown in FIG. 5-7 , in another embodiment, the mounting frame portion 11 of the frame 10 is detachably connected to the temple 12 , that is, the temple 12 can be separated from the mounting frame portion 11 .

[0091] The two temples 12 are detachably connected to the mounting frame 11. The temples 12 are connected to the mounting frame 11 of the frame 10 by snapping, plugging, magnetic connection, etc., so that the temples 12 can be connected to or disconnected from the mounting frame 11. The temples 12 are detachably connected to the mounting frame 11, so that the temples 12 can be changed between the connected state and the disconnected state, and the first projection portion is detachable relative to the second projection portion.

[0092] Thus, when the augmented reality glasses 1 are not in use, the temples 12 can be detached from the mounting frame 11, thereby reducing the overall volume of the frame 10 when stored and making it easier to carry. Furthermore, the temples 12 can be detachably connected to the mounting frame 11, allowing different temples 12 to be selected to meet the wearing size requirements of different users.

[0093] The two temples 12 can be detachably connected relative to the mounting frame 11. The mounting frame 11 includes a frame 111 and an extension portion 112 arranged on both sides of the frame 111. The frame 111 is two frame bodies 1111 with two through holes 1112. The through holes 1112 are respectively arranged in each frame body 1111, and the two frame bodies 1111 are connected by a crossbeam 1113. The display component 22 is installed in the through hole 1112. The extension portion 112 is extended from the frame 111 away from the crossbeam 1113 in a direction perpendicular to the display component 22, that is, the extension portion 112 protrudes from the frame 111. The extension portion 112 is hollow inside, and an optical machine installation area 1121 is formed. The second projection portion is arranged in the optical machine installation area 1121. The frame 111 and the extension 112 are integrally formed to simplify the molding process of the mounting frame 11 and increase the overall strength and rigidity of the mounting frame. The materials of the mounting frame 11 include, but are not limited to, metal, plastic, resin, etc.

[0094] The temple 12 extends as a whole along its length and includes a mounting portion 121, a wearing portion 122 extending rearward from the mounting portion 121, and a cover plate 123. The mounting portion 121 is adjacent to the extension portion 112 of the mounting frame 11, while the wearing portion 122 is distal to the extension portion 112. The mounting portion 121 and the wearing portion 122 are provided with a receiving cavity, and a first projection portion and other functions are disposed within the mounting portion 121 and the wearing portion 122. The first projection portion is disposed within the mounting portion 121 and adjacent to the extension portion 112 of the mounting frame 11. The wearing portion 122 can be mounted on the user's ear to enable the augmented reality glasses 1 to be worn. The cover plate 123 seals the mounting portion 121 and the wearing portion 122. This design allows the mounting portion 121 and the wearing portion 122 to be sealed after each component is installed within the receiving cavity of the mounting portion 121, making the assembly process simple and efficient. The mounting portion 121 and the wearing portion 122 may be integrally formed to form the temple 12 together with the cover plate 123 .

[0095] When the augmented reality glasses 1 are worn, the inner side is closer to the user's head, and the outer side is farther away from the user's head. The mounting portion 121 of the temple 12 is designed to protrude outward. This allows the mounting portion 121 to accommodate the larger first projection portion and, at the same time, to fit the width of the mounting portion 121 with the extension portion 112 of the mounting frame 11. Furthermore, the mounting portion 121 does not occupy the gap between the temple 12 and the user's head, leaving ample room for heat dissipation.

[0096] The second projection portion is disposed on the extension portion 112 of the mounting frame portion 11 , and the first projection portion is disposed on the mounting portion 121 of the temple 12 . The first projection portion and the second projection portion constitute a complete projection assembly 21 for realizing projection imaging.

[0097] Specifically, the projection assembly 21 includes a light source module 211, at least one light deflection element 212, a display module 213, and a projection lens 214. The light source module 211 provides outgoing light, the light deflection element 212 changes the light's optical path, the display module 213 forms a corresponding image, and the projection lens 214 directs the light into the display assembly 22. The various components of the projection assembly 211 form a complete projection optical path. Light emitted from the light source module 211 passes through the at least one light deflection element 212, forms an image in the display module 213, and then projects a corresponding virtual image through the projection lens 214. The projection lens 214 is positioned closest to the display assembly 22, with its optical axis perpendicular to the display assembly 22. In some embodiments, the light source module 211 is positioned parallel to the optical axis of the projection lens 214, so that the optical axis of the light emitted from the light source module 211 is parallel to and centered on the optical axis of the projection lens 214. In some optional embodiments, as shown in FIG10 , the light source module 211 of the projection assembly 21 is a first projection portion, disposed within the mounting portion 121 of the temple 12. The light deflection element 212, display module 213, and projection lens 214 of the projection assembly 21 are a second projection portion, disposed within the cavity of the extension portion 112. When the optical axis of the light emitted by the first projection portion is aligned with the center of light incident on the second projection portion, the first and second projection portions form a complete projection optical path, achieving projection imaging.

[0098] In other optional embodiments, as shown in FIG10 , the light source module 211, the light transfer element 212, and the display module 213 of the projection assembly 21 constitute a first projection portion, which is disposed in the mounting portion 121 of the temple 12. The projection lens 214 of the projection assembly 21 constitutes a second projection portion, which is disposed within the extension portion 112. When the optical axis of the light emitted by the first projection portion is aligned with the center of light incident on the second projection portion, the first projection portion and the second projection portion constitute a complete projection optical path, thereby achieving projection imaging.

[0099] A first optical path hole 1212 is formed on a first end surface 1211 of the temple 12 facing the extension portion 112, and a second optical path hole 1123 is formed on a second end surface 1122 of the extension portion 112 of the mounting frame 11 facing the temple 12. When in a disengaged state, the first optical path hole 1212 and the second optical path hole 1123 are staggered, and the components of the projection assembly 21 are inoperative. When in an engaged state, the first optical path hole 1212 and the second optical path hole 1123 are coaxially arranged, and the optical axis of the light emitted by the first projection portion and the light incident center of the second projection portion are aligned. This allows all light emitted by the light source module 211 to pass through the first optical path hole 1212 and the second optical path hole 1123 before reaching the projection lens 214 of the projection assembly 21 and entering the coupling region of the display assembly 22 through the projection lens 214.

[0100] In some optional embodiments, a slot is provided on the second end surface 1211 of the extension portion 112 of the mounting frame 11 facing the temple 12, and a buckle 1213 is provided on the first end surface 1211 of the mounting portion 121 of the temple 12 facing the extension portion 112, wherein the slot and buckle 1213 are adapted to each other. The mounting frame 11 and the temple 12 are connected by a snap connection, so that the temple 12 and the mounting frame 11 can be easily and conveniently installed and removed, making them easier for users to carry. The installation between the temple 12 and the mounting frame 11 enables the first projection portion and the second projection portion to form a complete projection optical path, achieving projection imaging.

[0101] The buckles 1213 of the temple 12 protrude outward from the first end surface 1211 and may be multiple. They protrude from the first end surface 1211 toward one side of the extension portion 112 and are positioned outside the first optical path through hole 11123. The extension portion 112 of the mounting frame 11 also has multiple slots recessed inward from the second end surface 1212. These slots are positioned outside the second optical path through hole 1123 and correspond in number and position to the buckles 1213. When the buckles 1213 of the temple 12 engage with the slots of the extension portion 112 of the mounting frame 11, the temple 12 and the mounting frame 11 are connected, and the first projection portion communicates with the second projection portion.

[0102] In some optional embodiments, the extension portion 112 of the mounting frame 11 can be detachably connected to the mounting portion 121 of the temple 12 via a connecting assembly 13. The connecting assembly 13 includes a second connecting portion 132, which is fixed to the extension portion 112. The temple 12 is connected and fixed to the extension portion 112 via the second connecting portion 132.

[0103] In some embodiments, the second connecting portion 132 further includes a base 1322 and a fixing frame 1323. The base 1322 is fixedly connected to the extension portion 112 of the mounting frame 11, and together with the extension portion 112, forms an annular structure with a receiving cavity. The fixing frame 1323 secures the second projected portion to the base 1322 along its length, thereby securing the second projected portion to the mounting frame 11. The base 1322 further includes a fixed end 13221 and an extended end 13222. The fixed end 13221 extends along its length, while the extended end 13222 extends along its width. The fixing frame 1322 secures the second projected portion to the fixed end 13221 of the base 1321. One side of the extended end 13222 contacts and secures the second end surface 1122 of the extension portion 112. When in a coupled state, the other side is disposed opposite the first end surface 1211 of the mounting portion 121 of the temple 12. The extending end portion 13222 includes a light path hole 13223 coaxially arranged with the second light path hole 1123 , so that the light projected by the first projection portion passes through the light path hole 13223 , enters the second light path hole 1123 , and reaches the second projection portion.

[0104] The side of the extended end portion 13222 that is opposite the first end surface 1211 of the mounting portion 121 of the temple 12 is provided with a latching slot 13224, which corresponds in number and position to the latches 1213 of the temple 12. When the latches 1213 of the temple 12 engage with the latching slot 13224 of the second connecting portion 132, the temple 12 is connected to the mounting frame 11, and the first projection portion is connected to the second projection portion.

[0105] In some embodiments, a screw-on groove is provided on the side of the extension end portion 13212 that is opposite to the second end face 1122 of the extension portion 112. The buckle 1213 enters the screw-on groove through the slot 13224 of the second connecting portion 132 and is fastened to the screw-on groove, thereby tightly fixing the temple 12 to the extension portion 112.

[0106] In some embodiments, a slot can be set on the temple 12, and a buckle is set on the extension portion 112 of the mounting frame 11. The number and position of the slots and buckles correspond one to one. When the buckle of the extension portion 112 of the mounting frame 11 is engaged in the slot of the temple 12, the connection between the temple 12 and the mounting frame 11 is realized.

[0107] In some embodiments, since the projection assembly 21 occupies a considerable space, the dimensions of the extension portion 112 and the mounting portion 121 in the direction perpendicular to the optical axis are also relatively large. When the end face space is limited, the card slot of the extension portion 112 of the mounting frame 11 or the card slot 13224 on the second connecting portion 132 and the buckle 1213 of the temple 12 are arranged at the four corners or edges to achieve a reasonable spatial layout.

[0108] When the augmented reality glasses 1 are normally worn, the temple 12 engages with the extension 112 of the mounting frame 11, forming a mounted and coupled state. The two temples 12 face each other relative to the mounting frame 11. The first projection of the temple 12 and the second projection mounted on the extension 112 are aligned, and the temple 12 and the extension 112 extend in parallel. The second end surface 1122 of the extension 112 is parallel to the first end surface 1211 of the mounting portion 121, and the angle α1 between the two end surfaces is 0°. The first optical path opening 1212 of the temple 12 is coaxial with the second optical path opening 1123 of the extension 112. When the first projection located on the mounting portion 121 of the temple 12 and the second projection located on the extension 112 are electrically conductive, the light source module 211 can be powered on to illuminate and emit light, and the display module 211 is in operation. When the optical axis of the light emitted from the first projection portion is aligned with the center of light incident on the second projection portion, a complete optical path is formed. The light emitted from the first projection portion passes through the first optical path through hole 1212 and the second optical path through hole 1123 to reach the second projection portion, and then passes through the projection lens 214 and is coupled into the display assembly 22.

[0109] When the temple 12 of the augmented reality glasses 1 is separated from the extension 112 of the mounting frame 11, the optical axis of the light emitted by the first projection portion is offset from the center of light incident on the second projection portion. At this point, the circuits between the first projection portion of the temple 12 and the second projection portion of the extension 112 are disconnected, and the light source module 211 is de-energized.

[0110] When the augmented reality glasses 1 are switched from a separated state to a combined state to meet the needs of normal wear and use, the temple 12 is engaged with the extension portion 112 of the mounting frame 11, the second end surface 1122 of the extension portion 112 is in parallel contact with the first end surface 1211 of the mounting portion 121, the first optical path hole 1212 of the temple 12 is coaxially arranged with the second optical path hole 1123 of the extension portion 112, and the optical axis of the incident light of the first projection portion of the temple 12 and the incident light center of the second projection portion mounted on the extension portion 112 are aligned. When the circuits of the first projection portion and the second projection portion are connected, the light source module 211 can be switched from an unpowered state to an energized state, that is, the light source module 211 illuminates the outgoing light.

[0111] To detect the positional relationship between the buckle 1213 and the slot, the light source module 211 switches between different states. In some embodiments, the frame 10 is provided with a sensing device for detecting the position between the buckle 1213 and the slot. The sensing device is connected to a control unit and outputs different signals in different states. The sensing device can be a pressure sensor, a Hall effect sensor, or the like.

[0112] In some embodiments, the end of the buckle 1213 is provided with a circuit contact piece, and the interior of the card slot is provided with a circuit contact adapted to the circuit contact piece. When the buckle 1213 and the card slot are fully installed by snapping together and snapping into a predetermined position, the two come into contact through the contact points, thereby achieving a circuit connection between the light source module 211 or other components on the temple 12 and other components in the extension portion 112, so that the light source module 211 can be illuminated and emit light. In some embodiments, a switch device can also be provided. When the switch device is turned on, the switch device is connected to the circuit of the light source module 211, turning on the light source module 211 to illuminate and project light.

[0113] In some embodiments, the second projection portion extends outwardly with an FPC soft row, and the first projection portion has an interface board. When the buckle of the extension portion 112 of the mounting frame portion 11 is engaged in the slot of the temple 12, the FPC soft row is connected to the interface board of the first projection portion, thereby achieving circuit conduction of the first projection portion.

[0114] The two temples 12 include a first temple 12-L and a second temple 12-R, wherein the first temple 12-L is located on the left side of the mounting frame 11, and the second temple 12-R is located on the right side of the mounting frame 11, and the first temple 12-L and the second temple 12-R can be detachably installed relative to the mounting frame 11.

[0115] Correspondingly, the mounting frame 11 includes a frame 111 and an extension 112. The two through holes 1112 of the frame 111 of the mounting frame 11 include a first through hole 1112-L and a second through hole 1112-R, wherein the first through hole 1112-L is located on the left side of the frame 1111, and the second through hole 1112-R is located on the right side of the frame 1111. The extension 112 includes a first extension 112-L and a second extension 112-R, wherein the first extension 112-L is formed perpendicularly to the frame 1111 from the left side, and the second extension 112-R is formed perpendicularly to the frame 1111 from the right side. The display assembly 22 includes a first display assembly 22-L and a second display assembly 22-R. The first display assembly 22-L is mounted in the first through hole 1112-L, and the second display assembly 22-R is mounted in the second through hole 1112-R. When the augmented reality glasses 1 are in use, the first through hole 1112-L corresponds to the user's left eye viewing angle, and the second through hole 1112-R corresponds to the user's right eye viewing angle, so that the light coupled out of the display assembly 22 can enter the user's eyes.

[0116] The first extension portion 112-L of the mounting frame 11 is provided with a first slot near the end face 1121 of the temple 12, and the second extension portion 112-R is provided with a second slot. The first temple 12-L is provided with a first buckle 1213-L near the end face 1211 of the extension portion 112, and the second temple 12-R is provided with a second buckle 1213-R near the end face 1211 of the extension portion 112. The first slot and the first buckle 1213-L are adapted to each other, and the second slot and the second buckle 1213-R are adapted to each other. The mounting frame 11 and the temple 12 are connected by a snap connection, so that the first temple 12-L and the second temple 12-R can be easily installed and removed from the mounting frame 11.

[0117] The frame 10 further includes a lens ring 14, which secures the projection display system 20 to the frame 10. The lens ring 14 comprises a lens ring 141 and a lens ring 142, and may be integrally formed. The lens ring 141 secures the display assembly 22 to the frame 111 of the mounting frame 11, specifically securing the optical lenses in the through-holes 1112 of the frame 111. The lens ring 142 secures the projection lens 214 to the extension 112 of the mounting frame 11.

[0118] The lens ring 14 provides a mounting calibration surface for the projection lens 214 of the projection assembly 21, so that when the second projection portion of the projection assembly 21 is mounted on the extension portion 112, it is optically compatible with the display assembly 22, that is, the light projected by the projection assembly 21 can enter the coupling area of ​​the display assembly 22, realizing virtual imaging.

[0119] The light source module 211 of the projection assembly 21 can be an LED light source with high luminous efficiency and low cost, or an LED lamp bead or light bar. The light source module 211 can also be provided with two or three components (e.g., a red light source, a blue light source, and a green light source). The three corresponding light source components can be provided in a single structural member and then combined through a color combining optical element to form an RGB light source.

[0120] In some embodiments, as shown in Figures 9 and 10, the light source module 211 is a three-color light source, with two monochromatic light sources disposed on the side. Light from the two light sources is deflected by a light-deflecting element and combined with another monochromatic light source to form an RGB light source, which then emits light toward the display module 213. Since the light source generates a large amount of heat during operation, the two monochromatic light sources are disposed on the outside, away from the user's head. This not only satisfies the heat dissipation requirements of the light source module 211 but also prevents the light source module 211 from overheating and scalding the user's head during operation. The two monochromatic light sources are disposed on the same side, reducing the width of the light source module 211, thereby reducing the width of the first projection portion and the width of the temple 12.

[0121] The light source module 211 may also include a light-homogenizing element (such as a collimating mirror, not shown) provided with the corresponding light source, and the light emitted by the light source enters the light-deflecting element after passing through the light-homogenizing element. The uniform element can adjust the light emitted by the light source. Since the light emitted by the light source is generally natural light, the light is diffused light and has a certain emission angle. Therefore, in order to ensure the light output efficiency, the uniform element is provided between the light source and the light deflecting element to adjust the light emitted by the light source and reduce the divergence angle, thereby ensuring that the light of the light source enters the rear optical element uniformly, thereby improving the efficiency of the light source. In some embodiments, the side of the uniform element facing the light source is a plane, and the side facing away from the light source is a convex surface, and the area of ​​the plane is larger than the luminous area of ​​the light source.

[0122] The display module 213 of the projection module 21 includes at least one display chip 2131 and a substrate 2132, with the display chip 2131 attached to the substrate 2132. The substrate 2132 can be made of ceramic or metal to provide greater strength and heat dissipation. The display chip 2131 can modulate the light emitted by the light source module 211 to form an image, and may include at least one of a DLP (Digital Light Processing) chip, an LCOS (Liquid Crystal on Silicon) chip, an LBS (Laser Bean Scanning) chip, an OLED (Organic Light-Emitting Diode) chip, a Mini LED chip, and a Micro LED chip.

[0123] In some embodiments, the display chip 2131 is a liquid crystal on silicon (LCOS) display chip. LCOS display chips are a new type of reflective micro-LCD projection technology. They use a CMOS integrated circuit chip coated with liquid crystal silicon as the substrate for the reflective LCD. After being polished and plated with aluminum to serve as a reflector, this forms the CMOS substrate. The CMOS substrate is then bonded to a glass substrate containing transparent electrodes, and liquid crystal is injected into the substrate to form the package. When receiving light, the reflective state of each pixel of the LCOS display chip can be controlled, thereby achieving light reflection at different locations, thereby forming the desired image.

[0124] As shown in Figure 9, the light deflecting element 212 of the projection assembly 21 can at least partially deflect the light emitted by the light source to the display chip 2131 (the S light emitted by the light source module 211 is deflected and reflected to the LCOS chip), or can at least partially deflect the light returned by the display chip 2131 to the projection lens 214 (see Figure 6, the S light used to form the projection image is deflected and reflected to the projection lens 214). Therefore, the light deflecting element 212 can have the function of splitting and combining lights, and can specifically be but not limited to a PBS (Polarization Beam Splitter) prism, and can also be a TIR (Total Internal Reflection) prism.

[0125] Referring to FIG9 , the LCOS chip represents the display chip 2131, which can modulate the light emitted by the light source module 211 to form an image. The PBS prism represents the light deflection element 212. In some embodiments, the LCOS chip, the PBS prism, and the projection lens 214 form a straight optical path. By fixing their positions during assembly so that they are arranged along a substantially straight line, a straight optical path can be formed. During the projection imaging process, light emitted by the light source module 211 enters the PBS prism via a collimator. The S light of the light is substantially completely deflected by the PBS prism and reflected onto a wave plate (not shown) and a total reflection mirror. The wave plate converts the S light into P light, which is then reflected by the total reflection mirror onto the PBS prism. The P light passes through the PBS prism and is projected onto the LCOS chip. The LCOS chip proportionally and controllably converts the P light received by different pixels into S light for forming the projected image. The S light for forming the projected image is deflected by the PBS prism and reflected onto the projection lens 214.

[0126] Furthermore, the display module 213 , the light-transfer element 212 , and the projection lens 214 are arranged along the length direction to form a straight light path, thereby reducing the width.

[0127] In some embodiments, as shown in Figures 9 and 10, the display chip 2131 is arranged on the outer side away from the user's head, and the total reflection prism is arranged on the inner side, so that the display chip 2131 that generates a large amount of heat can have sufficient heat dissipation space and protect the user from being burned by overheating.

[0128] The display assembly 22 is an optical lens that can be in the form of a sheet or plate and can conduct light. In some optional embodiments, the optical lens can include an optical waveguide. The optical waveguide solution can be at least one of an arrayed waveguide, a diffraction waveguide, and a volume holographic waveguide solution, utilizing optical phenomena such as reflection or diffraction to expand the exit pupil and achieve virtual and real fusion.

[0129] The display assembly 22 is an optical lens comprising a substrate 221 made of an optical waveguide material. The substrate 221 has a first optical plane and a second optical plane opposite the first optical plane. The optical waveguide material comprising the substrate 221 can be optical glass or optical resin. The optical lens serves as a path for light to pass through. The optical lens includes an incoupling region and an outcoupling region disposed on the substrate 221. The image generated by the projection assembly 21 enters the interior of the waveguide lens through the incoupling region, is transmitted to the outcoupling region after total internal reflection from the waveguide lens, and is emitted from the outcoupling region to the user's eyes. Furthermore, as shown in FIG2 , the display assembly 22 includes a main body region 222 and an extension region 223 extending from the main body region 222 away from the crossbar 1113. The main body region 222 covers the through-hole 1112 of the mounting frame 11, and the extension region 223 is disposed in the frame of the mounting frame 11 away from the crossbar 1113. The incoupling region is disposed in the extension region 223, and the outcoupling region is disposed in the main body region 222. The incoupling zone and outcoupling zone are located on the surface of the optical lens closest to the user. The outcoupling zone is opposite the user's eyes; that is, the center of the outcoupling zone is located on the visual axis of the user's eyes. The incoupling zone is located on the side away from the user's eyes. The projection assembly 21 is used to output the image generated by the display chip 2131 to the incoupling zone of the optical lens.

[0130] Furthermore, the projection lens 214 of the projection assembly 21 is positioned in a coupling region adjacent to the display assembly 22. The dimensions of the coupling region correspond to the dimensions of the output beam from the projection lens 214, allowing all light emitted from the projection lens 214 to pass through the coupling region and enter the display assembly 22. By extending only an extension region 223 that is approximately the same size as the coupling region, the overall size and weight of the display assembly 22 can be reduced, preventing the display assembly 22 from being too large, which would result in a larger size for the augmented reality glasses 1. The coupling region of the display assembly 22 is positioned adjacent to the extension portion 112 of the mounting frame 11, while the decoupling region is positioned away from the extension portion 112, enabling compact installation with the projection assembly 21, thereby improving the overall structural compactness of the AR glasses.

[0131] The optical waveguide can be a grating waveguide solution, and the optical waveguide lens can have a nano-pattern formed on the internal or external surface, such as a curved grating structure. The optical waveguide lens can adjust the path of light and output a virtual image. It can include an in-coupling grating and an out-coupling grating, a region where visible light is incident, and a region where visible light is totally reflected. The in-coupling grating is located in the in-coupling region, and the surface of the in-coupling grating is provided with a microstructure for changing the incident angle of light, thereby coupling the light into the substrate 221. The in-coupling grating can change the incident angle of the incident light entering the interior of the substrate 221, so that the incident angle is greater than or equal to the critical angle, thereby allowing the light to be totally reflected within the substrate 221, completing the light transmission.

[0132] In some embodiments, the optical waveguide can be provided with a first diffraction grating region and a second diffraction grating region, respectively, on a substrate 221 formed of an optical waveguide material, wherein the first diffraction grating region is provided on a first optical plane of the substrate 221, and the second diffraction grating region is provided on a second optical plane of the substrate 221, opposite the first optical plane. With this arrangement, the first diffraction grating region provided on the first optical plane of the substrate and the second diffraction grating region provided on the second optical plane of the substrate, opposite the first optical plane, are opposite to each other on opposite sides of the substrate and preferably at least partially overlap. As a result, within the relatively overlapping grating regions, light is diffracted and propagates between the two relatively overlapping grating interfaces in the waveguide.

[0133] Therefore, after the image light emitted by the projection component 21 is coupled into the display component 22 through the coupling-in area, it undergoes multiple total reflections and diffractions in the substrate 221 of the display component 22 to achieve diffusion, transmission and coupling-out, and finally the image can be seen in the coupling-out area.

[0134] The main body area 222 of the display assembly 22 may also include a transparent area. The optical lens portion of the transparent area may be formed of glass, plastic, or polymer, and may be transparent or translucent. The transparent areas may be respectively arranged to face the user's eyes.

[0135] The projection assembly 21 corresponds to the coupling-in area of ​​the display assembly 22. That is, the light emitted by the projection assembly 21 is aligned with the coupling-in position of the display assembly 22, and the angle at which it enters the coupling-in grating is consistent with a predetermined angle, thereby providing a clear virtual image to the user. An optical element may also be included between the projection assembly 21 and the display assembly 22 to achieve optical path angle conversion. In some embodiments, the optical element may be positioned at the light exit point of the projection lens 214 of the projection assembly 21, or at the coupling-in area of ​​the display assembly, to adjust the position and angle of the light emitted by the projection assembly 21.

[0136] The frame 10 also includes a nose pad, which is movably connected to the mounting frame 11. The mounting frame 11 is movably connected to the side of the mounting frame 11 that faces the eye. The nose pad rests against the user's nose bridge when the user wears the frame 10, providing effective front support for the glasses. The nose pad can be connected to the frame 111 of the mounting frame 11 via a hinge or other means to allow the nose pad to rotate relative to the frame 111. Alternatively, the nose pad can be directly connected to the frame 111 via a removable means such as a snap connection.

[0137] The frame 111 may also include a frame adjustment member that can adjust the distance between the left and right mounting frame portions to accommodate users with different pupil distances, thereby improving wearing comfort and the versatility of the glasses.

[0138] The augmented reality glasses 1 also include a host control module 60 and other functional units, including but not limited to a sound output module, an audio module, a sensor, a camera, etc.

[0139] The host control module 60 can control the projection assembly 21 to project images, and also control at least one other functional unit, such as data processing or calculation of the data processing module 30 and signal input and output of the signal transmission module 50.

[0140] The sound output module can output the sound signal to the outside, and the audio module can include a speaker or a receiver. The audio module can convert the sound into an electrical signal, and vice versa. According to one embodiment, the audio module can obtain sound through the input module, or output sound through the sound output module or can be coupled to an external electronic device (such as an electronic device such as headphones) through the signal transmission module 50 and the external electronic device to convert the sound into an electrical signal for output.

[0141] The sensor can detect the operating state of the electronic device (e.g., power or temperature) or the environmental state outside the electronic device (e.g., the state of the user), and then generate an electrical signal or data value corresponding to the detected state. According to one embodiment, the sensor module can include, for example, a gesture sensor, a gyroscope sensor, an air pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

[0142] The camera can capture images and may include at least one lens, an image sensor, etc. The image output by the camera overlaps with the virtual image information output by the processor to achieve an AR experience.

[0143] Among them, the host control module 60 and other functional units are arranged on the temple 12. On the one hand, the structure of the main body of the glasses arranged in front of the user's eyes is made compact and miniaturized. On the other hand, the overall center of gravity of the augmented reality glasses 1 is adjusted to the rear side to improve wearing comfort.

[0144] There are two main types of augmented reality displays: video see-through and optical see-through. Augmented reality glasses use translucent lenses, allowing the human eye to see the external real-world scene directly through the lenses. When using video see-through display, the glasses can superimpose the environmental image captured by the camera with virtual image information and display it on a virtual screen in the form of a video or image stream. The image displayed on the virtual screen does not overlap with the real-world scene directly seen by the human eye, that is, the virtual and the real do not overlap.

[0145] When the optical perspective method is adopted, the augmented reality glasses use optical principles and equipment to directly superimpose the enhanced information on the corresponding position in the real picture seen by the human eye through the lens through the data processing module 30, and only the enhanced information is displayed on the screen.

[0146] The video perspective display method uses a camera set on the augmented reality glasses to capture real-time images, that is, to display environmental images. The data processing module 30 can process the real projection environment and generate an environmental image to be played, and output it to the host control module 60. The host control module 60 controls the projection component 21 to image the display image. The virtual image information output by the processor and the real image information output by the camera are overlapped and projected at a preset position, making the user experience more realistic and allowing users to obtain a better AR experience.
