Abstract
Description
Technical Field
[0001] This application relates to the field of AR technology, specifically to an AR glasses. Background Technology
[0002] AR glasses are smart wearable devices that synthesize digital information into the real world, providing users with an experience different from reality. They typically use a display module in conjunction with regular glasses. The regular glasses are worn normally, while the display module projects the AR image onto the front of the glasses so the wearer can see it. Currently, most manufacturers' AR glasses are heavy, causing discomfort during prolonged wear, and are inconvenient to disassemble, replace, or repair, negatively impacting the user experience. Utility Model Content

[0022] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0023] Please refer to Figure 1 , Figure 2 As shown, this application embodiment provides an AR glasses, including: a glasses body 10, a waveguide display module 11 is disposed on one side of the lens 102 of the glasses body 10, and the waveguide display module 11 is hinged to the glasses body 10.
[0024] The main body of the glasses 10 is used to realize the functions of ordinary glasses, and the waveguide display module 11 is used to realize the AR function when applied to AR glasses.
[0025] The waveguide display module 11 is hinged to the glasses body 10, which enables the waveguide display module 11 to be quickly removed or replaced from the glasses body 10, facilitating maintenance. It also allows the waveguide display module 11 to be flipped off the glasses body 10, enabling switching between AR glasses functions and ordinary glasses functions to suit different application scenarios. This reduces the weight of the AR glasses, improves wearing comfort, and reduces energy consumption.
[0026] Among them, reference Figure 3 As shown, the waveguide display module 11 includes a waveguide bracket 110, on which a waveguide sheet 111 and an optical engine 112 are disposed. The optical engine 112 is located between the waveguide sheet 111 and the lens 102. The waveguide bracket 110 and the frame 101 of the glasses body 10 are hinged together by a hinge 12.
[0027] The waveguide bracket 110 serves as the supporting structure for the waveguide display module 11. Its shape is consistent with the frame 101 of the glasses body 10. Two waveguide sheets 111 are provided on the waveguide bracket 110. The waveguide sheets 111 are made of transparent glass. The two waveguide sheets 111 are correspondingly arranged with the two lenses 102 of the glasses body 10. The optical engine 112 is located between the two waveguide sheets 111. The optical engine 112 is also provided with an optical engine cover 113, which faces the glasses body 10.
[0028] Waveguide 111 can achieve total internal reflection of light. After the optical engine 112 completes the imaging, it couples light into the substrate of waveguide 111. Through the principle of total internal reflection, the light is transmitted to the front of the glasses and then released. The light emitted by the optical engine 112 enters the entrance pupil area of waveguide 111. After propagation through waveguide 111, the image is transmitted to the front of lens 102. The eye of the person wearing the glasses can see the image emitted by waveguide 111, thus realizing the AR function. Since all the light enters the entrance pupil area of waveguide 111, the imaging effect of AR glasses will be better.
[0029] Waveguide 111 is typically made of glass because glass generally has low optical loss, allowing optical signals to travel a longer distance within the glass waveguide 111 and reducing the need for signal amplifiers. Furthermore, glass has a high refractive index, which helps improve the light-trapping capability of the waveguide 111, enabling more light to propagate within it and increasing transmission efficiency. Simultaneously, glass can withstand significant temperature variations without affecting its performance, ensuring the stable operation of the optical communication system.
[0030] For example, the waveguide sheet 111 and the waveguide bracket 110 can be assembled and fixed with glue. This fixing method is simple, easy to implement, and firmly fixed without the need for additional fixing devices or increasing the overall weight of the AR glasses.
[0031] The waveguide sheet 111 and the waveguide bracket 110 can be fixed with glue, allowing the optomechanical system 112 to be adjusted and fitted onto the waveguide bracket 110. The hinge 12 is also mounted on the waveguide bracket 110. Figure 3 The central hinge 12 is located directly above the waveguide bracket 110. The optical engine 112 can be connected to the hinge 12 via a flexible circuit board (FPC). The optical engine cover 113 is then assembled onto the optical engine 112. The optical engine cover 113 is positioned towards the lens 102 of the eyeglass body 10, thereby forming the waveguide display module 11.
[0032] The optical engine cover 113 houses the optical engine 112, preventing contamination of the optical engine 112. The optical engine 112 can emit light through the optical engine cover 113 toward the waveguide sheet 111 of the waveguide display module 11 for forming AR images.
[0033] The flexible circuit board can control the movement of the optomechanism 112 and the hinge 12. By starting and stopping the optomechanism 112, the hinge 12 is activated, thereby enabling the waveguide display module 11 to flip according to the opening of the optomechanism 112.
[0034] Flexible circuit boards can be rolled and folded, allowing for more compact assembly in AR glasses, thus reducing the weight and size of the AR glasses.
[0035] The main body of the glasses 10 includes a frame 101 and temples 103. The frame 101 is provided with two lenses 102, and a nose pad is provided between the two lenses 102. The lenses 102 can be ordinary lenses to realize the functions of ordinary lenses, or they can be AI smart lenses to realize AI functions.
[0036] In some embodiments, the temple 103 is provided with a circuit board, a battery, a speaker, etc., and the circuit board, battery, and speaker are connected to the frame 101 of the eyeglass body 10 through a flexible circuit board to realize the corresponding functions.
[0037] For example, the circuit board is connected to the optomechanical 112 via a flexible circuit board. The AR display function of the waveguide 111 can be realized through the control of the circuit board. The battery can be connected to the optomechanical 112. By controlling the start and stop of the battery, the power supply to the optomechanical 112 can be cut off.
[0038] During assembly, the waveguide display module 11 is inserted into the frame 101 via the latch of the hinge 12, and at the same time, the FPC or pogo pin (a type of hardware terminal used for connection) inside the latch is functionally connected to the frame 101.
[0039] In summary, the AR glasses provided in this application embodiment have a waveguide display module 11 hinged to the glasses body 10. This hinge allows the waveguide display module 11 to be quickly inserted into the glasses body 10 to achieve AR display functionality. It also facilitates disassembly, repair, and replacement of the waveguide display module 11. When the display function of the waveguide display module 11 is not in use, it can be detached from the glasses body 10 to reduce the user's wearing weight and improve wearing comfort. Furthermore, the hinged design allows the waveguide display module 11 to be flipped when the display function is not in use, enabling the use of the glasses body 10's lenses 102 for normal wear or AI Bluetooth functions, thus saving battery power. This allows the AR glasses of this application to flexibly switch between AR glasses functions and normal glasses functions, making them suitable for different application scenarios and improving the customer experience.
[0040] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
