Description

Technical Field

[0001] This application relates to the field of smart glasses technology, and in particular to a frame assembly, a lens module, a lens assembly, and smart glasses. Background Technology

[0002] With the rapid development of technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), smart glasses can also achieve near-eye display of images in front of the user's line of sight, and can also display images of real environment and virtual objects in real time by overlay.

[0003] In related technologies, smart glasses may include a frame and a display component. The frame includes two lenses, each with a waveguide. When the frame is worn on the user's head, the two waveguides are positioned in front of the left and right eyes, respectively. However, the frames in these technologies are full-rim structures, resulting in a full-rim design for the smart glasses and reducing the user experience. Utility Model Content

[0004] This application provides a frame component, a lens module, a lens assembly, and smart glasses, enabling smart glasses with a semi-rimless design, which can improve the user experience.

[0005] In a first aspect, embodiments of this application provide a frame assembly for integration into smart glasses. The smart glasses include a frame and a waveguide fixedly connected to the frame. The frame assembly includes a frame and a first flexible member. The frame is configured to be detachably connected to the frame, and is further configured to form a first through-hole with the frame that exposes a portion of the waveguide. The frame includes a first groove, with a portion of the waveguide located inside the first groove, and the waveguide and frame are spaced apart. At least a portion of the first flexible member is disposed inside the first groove and contacts the inner wall of the first groove. The first flexible member is configured to contact the waveguide and is further configured to seal the gap between the frame and the waveguide.

[0006] In this embodiment, the bezel can be set around the edge of the lower half of the waveguide. The bezel is equivalent to the bottom of the existing eyeglass frame. However, the bezel is a one-piece structure, not composed of two structural components. This allows for a small-sized design in both the front-to-back thickness and the vertical width, simultaneously achieving a narrow bezel design and a thin bezel design. As a result, the eyeglass frame can be a semi-frame design. After the bezel is connected to the eyeglass frame, the size of the smart glasses can be reduced, improving the aesthetic appeal and enhancing the user experience.

[0007] Furthermore, by incorporating a first flexible element within the gap between the frame and the waveguide, direct contact between the waveguide and the frame is prevented, thus avoiding hard contact. This first flexible element also acts as a stress buffer, preventing damage to the waveguide. Additionally, the first flexible element is flexible and deformable, effectively sealing the gap between the waveguide and the frame, meeting the waveguide's reliability requirements.

[0008] In some possible implementations, the outer surface of the frame is made of metal, which allows for a high-gloss design and further enhances the aesthetic appeal of the smart glasses.

[0009] In some possible implementations, the frame is made of metal. This not only achieves a high-gloss design but also reduces the manufacturing difficulty of the frame. For example, the frame can be manufactured using a one-piece molding process such as stamping.

[0010] In some possible implementations, the frame includes a first connecting portion, a first arc-shaped portion, and a second connecting portion. The two ends of the first arc-shaped portion are respectively fixedly connected to the first connecting portion and the second connecting portion. The first arc-shaped portion includes a first groove. Both the first connecting portion and the second connecting portion include a second through hole, configured to allow a fastener for fixing the frame and the eyeglass frame to pass through. In this way, the frame can be detachably connected to the eyeglass frame via the fastener, ensuring the reliability of the connection between the frame and the eyeglass frame while simplifying the frame structure.

[0011] In some possible implementations, the first flexible element includes a second groove, with a portion of the waveguide located inside the second groove. The sidewalls and bottom of the second groove are in contact with the waveguide. This allows the gap between the waveguide and the inner wall of the first groove to be fully filled, preventing accidental contact between the waveguide and the frame.

[0012] In some possible implementations, the first flexible element includes silicone or foam. This serves as a stress buffer and can seal the gap between the waveguide and the frame.

[0013] In some possible implementations, the bezel further includes a third through-hole extending through the bezel along the thickness direction of the waveguide, configured to expose a portion of the corrective lens located inside the bezel. The bezel assembly also includes a second flexible element, which is annular in structure and located outside the first groove, configured to seal the gap between the inner side of the bezel and the corrective lens.

[0014] In this embodiment, the first flexible component seals the gap between the waveguide and the frame, and the second flexible component seals the gap between the inner side of the frame and the corrective lens. This prevents the gap between the waveguide and the corrective lens from being connected to the external environment, thus preventing dust and other foreign objects from entering the gap. After a period of time, there is no need to remove the myopia lens or clean the waveguide and the myopia lens, improving the user experience. Furthermore, since the myopia lens is fixed to the frame, it does not affect the waveguide, preventing damage. Additionally, the presence of the first and second flexible components seals the gap between the waveguide and the myopia lens, achieving waterproofing and dustproofing, avoiding frequent cleaning of the waveguide and the myopia lens.

[0015] In some possible implementations, the minimum width of the second flexible element is greater than or equal to 0.8 mm along the direction perpendicular to the thickness of the waveguide. This ensures that the second flexible element can seal the gap between the corrective lens and the inner side of the frame, resulting in good reliability.

[0016] In some possible implementations, the second flexible component includes an adhesive layer along the thickness direction of the waveguide, with one side of the adhesive layer bonded to the frame and the other side bonded to the corrective lens. In this way, the second flexible component not only seals the gap between the corrective lens and the frame but also secures the corrective lens to the frame, reducing the number of parts in the smart glasses and simplifying their structure.

[0017] In some possible implementations, the first flexible member includes an annular portion and a non-annular portion. A portion of the annular portion is located inside the first groove, and another portion is located inside the first groove. The annular portion is configured to seal the annular gap between the frame and the waveguide in the thickness direction of the waveguide. The non-annular portion is fixedly connected to the annular portion and is located inside the first groove. In this way, the first flexible member can effectively seal the gap between the frame and the waveguide, further improving the sealing effect.

[0018] In some possible implementations, the minimum width of the annular portion along the direction perpendicular to the waveguide's thickness is greater than or equal to 0.8 mm. This ensures that the first flexible element can seal the gap between the waveguide and the frame, resulting in good reliability.

[0019] In some possible implementations, the frame assembly also includes a corrective lens, located inside the frame and fixedly connected to it, covering the third through-hole. In this way, the corrective lens is part of the frame assembly, allowing the frame assembly to be pre-assembled and then connected to the frame, simplifying the process of replacing the frame assembly and improving replacement efficiency.

[0020] Secondly, embodiments of this application provide a lens module, including a corrective lens and a frame assembly as described in the first aspect. The corrective lens is located inside the frame of the frame assembly, and is fixedly connected to the frame, covering a third through-hole in the frame assembly. In this way, the corrective lens and the frame assembly are two independent parts, facilitating user customization of corrective lenses with different prescriptions.

[0021] Thirdly, embodiments of this application provide a lens assembly for integration into smart glasses. The smart glasses include a frame, and the lens assembly is configured to be disposed inside the frame. The lens assembly includes a corrective lens, an elastic member, and an annular frame member. The annular frame member is sleeved on and fixedly connected to the corrective lens. The annular frame member is configured to be detachably connected to the frame. One of the annular frame member and the frame includes a slot, and the other includes a buckle capable of engaging inside the slot. The elastic member is fixedly connected to the annular frame member and is configured to abut against the frame.

[0022] In this way, the lens assembly is detachably connected to the frame via a snap-fit ​​mechanism, allowing for quick replacement of the lens assembly. Furthermore, when the lens assembly is connected to the frame, an elastic element abuts against the frame, ensuring the lens assembly is firmly fixed to the frame. This prevents accidental separation of the lens assembly from the frame when the smart glasses move, thus improving the stability of the connection between the lens assembly and the frame.

[0023] In some possible implementations, the annular frame includes multiple latches, including a first latch and a second latch. Along the length of the frame, the first and second latches are located on opposite sides of the corrective lens, with the elastic element and the first latch located on the same side of the corrective lens. This provides a connection structure between the annular frame and the frame on both sides in the left-right direction, improving the reliability of the connection between the lens assembly and the frame.

[0024] In some possible implementations, the first and second latches have different structures. The outer sidewall of the first latch, perpendicular to the thickness direction of the corrective lens, is curved. This reduces the difficulty of the first latch engaging or disengaging from the first slot, and also reduces the difficulty of separating or assembling the lens assembly from the frame.

[0025] In some possible implementations, the elastic element includes a metal spring, which can reduce the manufacturing difficulty of the elastic element.

[0026] In some possible implementations, the elastic element is configured to insert into the third groove of the frame. This reduces the influence of the elastic element on the size of the gap between the frame and the annular frame, helping to minimize the gap between them.

[0027] In some possible implementations, the ring-shaped frame includes a metal frame and a pull cord. The metal frame includes either a buckle or a slot. The metal frame is fixedly connected to an elastic element, and both ends of the metal frame are fixedly connected to the two ends of the pull cord. The metal frame and the pull cord form a ring structure surrounding the corrective lens. In this way, the ring-shaped frame can be used with corrective lenses of different shapes, meeting the user's needs for changing corrective lenses.

[0028] Fourthly, embodiments of this application provide smart glasses, including a waveguide, a frame, and a bezel assembly as described in any of the first aspects. The waveguide is fixedly connected to the frame. The bezel assembly's bezel is detachably connected to the frame, and the bezel and frame enclose a first through hole, exposing a portion of the waveguide. In this way, the frame can be a semi-frame structure, enabling the creation of smart glasses with a semi-frame design, which helps improve the aesthetic appeal of the smart glasses and enhances the user experience.

[0029] In some possible implementations, the frame includes a fourth groove, with a portion of the waveguide located inside the fourth groove, and the waveguide spaced apart from the frame. The smart glasses also include a third flexible member, at least a portion of which is disposed within the fourth groove and contacts the inner wall of the groove. The third flexible member is configured to contact the waveguide and further configured to seal the gap between the frame and the waveguide. This avoids hard contact between the frame and the waveguide, and the third flexible member acts as a stress buffer, preventing damage to the waveguide. Furthermore, the deformation of the third flexible member can seal the edges of the waveguide, meeting the waveguide's reliability requirements.

[0030] Fifthly, embodiments of this application provide smart glasses, including a waveguide, a frame, and a bezel assembly as described in the first aspect. The waveguide is fixedly connected to the frame. The bezel assembly's bezel is detachably connected to the frame, and the bezel and frame enclose a first through hole, the first through hole exposing a portion of the waveguide. The frame is also configured to be detachably connected to a lens assembly as described in the third aspect, one of the annular frame members of the frame and the lens assembly including a slot and the other including a buckle, and the elastic members of the frame and the lens assembly abut against each other. In this way, the frame can be quickly connected to the lens assembly, which can meet the needs of store demonstration scenarios and allow users with different prescriptions to try them on.

[0031] In some possible implementations, the frame includes multiple slots, including a first slot and a second slot. The first slot is configured for a first latch of the annular frame member to be inserted, and the second slot is configured for a second latch of the annular frame member to be inserted. This provides a connection structure between the annular frame member and the frame on both sides in the left-right direction, improving the reliability of the connection between the lens assembly and the frame.

[0032] In some possible implementations, the frame also includes a third groove configured for partial insertion of the elastic element. This reduces the influence of the elastic element on the gap size between the frame and the annular frame member, helping to minimize the gap between them.

[0033] In some possible implementations, one of the sidewalls of the third groove is an inclined sidewall, configured to guide the elastic element away from the interior of the third groove. This prevents the elastic element from contacting the inner wall of the third groove during the separation of the lens assembly from the frame, ensuring the elastic element can leave the third groove.

[0034] In some possible implementations, smart glasses may also include lens assemblies as described in any of the third aspects. Attached Figure Description

[0060] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0061] This application provides a smart glasses 100, which may include, but is not limited to, virtual reality (VR) glasses, augmented reality (AR) glasses, or mixed reality (MR) glasses. This application example uses AR glasses as an example for illustration.

[0062] Figure 1 This is a schematic diagram of a smart glasses 100 provided in an embodiment of this application. It is understood that... Figure 1 The smart glasses 100 is shown only schematically; the actual shape, size, position, and construction of these components are not subject to change. Figure 1 The limitations of smart glasses 100 can also include, compared to Figure 1 More or fewer parts.

[0063] For example, in Figure 1 In this context, the Y direction can be forward or backward, the X direction can be left or right, and the Z direction can be up or down.

[0064] In the embodiments of this application, the description of the orientation of each part of the smart glasses 100 is based on the usage state when the smart glasses 100 is worn on the user's head. Front, back, left, right, up, and down are all directions when the smart glasses 100 is worn on the user's head.

[0065] When the smart glasses 100 are worn on the user's head, "front" refers to the direction from the back of the user's head towards the user's face, "back" is the opposite direction, "left" refers to the direction from the user's right ear towards the user's left ear, "right" is the opposite direction, "up" refers to the direction from the user's neck towards the top of the user's head, and "down" is the opposite direction.

[0066] In other words, when the Smart Glasses 100 is worn on an upright user's head, "front" refers to the direction from the user's back to the user's front, "back" refers to the direction from the user's front to the user's back, "left" refers to the direction from the user's right to the user's left, "right" refers to the direction from the user's left to the user's right, "top" refers to the direction from the user's bottom to the user's top, and "bottom" refers to the direction from the user's top to the user's bottom.

[0067] In some embodiments, see Figure 1The smart glasses 100 may include a frame and two waveguides 140, which are fixedly mounted on the frame and configured to correspond to the user's left and right eyes. The frame is configured to be worn on the user's head. When the smart glasses 100 are worn on the user's projection, the two waveguides 140 are located in front of the user's two glasses.

[0068] It should be noted that, in addition to the waveguide 140 and the frame, the smart glasses 100 may also include other components that enable the smart glasses 100 to function, such as, but not limited to, an optical engine, a motherboard, and a power supply. The optical engine can be positioned close to the waveguide 140 and is configured to project an image beam onto the waveguide 140, so that the waveguide 140 displays an image based on the image beam projected by the optical engine.

[0069] In some embodiments, the waveguide 140 may also be called an optical waveguide lens, waveguide sheet, optical waveguide plate, waveguide mirror, etc.

[0070] For example, waveguide 140 may include an inner cover plate, a waveguide layer and an outer cover plate stacked in the front-back direction, the inner cover plate and the outer cover plate protecting the waveguide layer and preventing damage to the waveguide layer.

[0071] In some embodiments, see also [link to previous document]. Figure 1 The frame may include a front frame 110 and two temples 130 respectively disposed at the left and right ends of the front frame 110. The lenses are disposed on the front frame 110. The front frame 110 is used to rest on the user's nose and is supported by the user's nose. The two temples 130 are used to rest on the user's two ears respectively and are supported by the user's two ears. When the smart glasses 100 is in use and is worn on the user's head, the front frame 110 is located in front of the user's eyes.

[0072] In some examples, the temple 130 can be fixedly connected to the front frame 110. For example, the temple 130 can be an integral structure with the front frame 110.

[0073] In other examples, the temple 130 can be hinged to the front frame 110 via a hinge assembly, allowing the temple 130 and the front frame 110 to be folded together for easy storage of the smart glasses 100.

[0074] In some embodiments, see also [link to previous document]. Figure 1The front frame 110 may include a nose bridge 112, two nose pads 180, and two eyeglass frames 111. The two eyeglass frames 111 are arranged side-by-side in the left-right direction. The nose bridge 112 is located between the two eyeglass frames 111 and is fixedly connected to each of the two eyeglass frames 111. The ends of the two eyeglass frames 111 furthest from the nose bridge 112 are each connected to a temple 130. Two waveguides 140 are respectively disposed on the two eyeglass frames 111. The two nose pads 180 are arranged side-by-side in the left-right direction and are fixedly connected to each of the two eyeglass frames 111. The two nose pads 180 are located on the inner side of the eyeglass frames 111 in the front-back direction. The inner side of the eyeglass frames 111 can be understood as the side of the eyeglass frames 111 closest to the user's face. The nose pads 180 are used to rest on the user's nose to support the front frame 110.

[0075] In some embodiments, the front frame 110 may also remove the nose pad 180 and use the nose bridge 112 to attach to the user's nose, so that the front frame 110 is attached to the user's nose.

[0076] In some examples, the nose pad 180 and the frame 111 can be a single integrated structure.

[0077] In other examples, the nose pad 180 can also be fixedly connected to the frame 111 by means of threaded connection, for example, by using screws to fix the nose pad 180 to the frame 111.

[0078] In some embodiments, the frame 111 can be a full-frame structure (e.g., Figure 1 As shown, the frame 111 is a ring structure. The frame 111 is fitted onto the waveguide 140. The frame 111 can seal the periphery of the waveguide 140 to meet the reliability requirements of the waveguide 140.

[0079] Figure 2 For the frame edge in related technologies Figure 1 A cross-sectional view along the AA direction.

[0080] In related technologies, see Figure 2 The full-frame structure of the mirror frame may include a front cover plate 310 and a bracket 320. The front cover plate 310 is located in front of the bracket 320 in the front-back direction. The front cover plate 310 and the bracket 320 are fixedly connected. The front cover plate 310 and the bracket 320 can form an annular structure that is fitted onto the waveguide 330.

[0081] However, due to the design requirements of smart glasses, the front cover 310 and the bracket 320 are relatively thick in the front-to-back direction at the bottom of the frame. This makes the overall size of the smart glasses appear larger and reduces the user experience.

[0082] Additionally, see also Figure 2Both the front cover plate 310 and the bracket 320 have stepped structures in the bottom area of ​​the frame. The stepped structures of the front cover plate 310 and the bracket 320 overlap each other, which can protect the side wall of the waveguide 330. However, this also results in a larger width of the bottom of the frame in the vertical direction, making the overall size of the smart glasses appear larger and reducing the user experience.

[0083] Figure 3 This is a frontal view of another structure of the smart glasses 100 provided in an embodiment of this application.

[0084] In the embodiments of this application, see Figure 3 The smart glasses 100 may include a waveguide 140 and a front frame 110. The front frame 110 may include a lens frame 111, a bridge 112, and a bezel assembly 120. The waveguide 140 is fixedly connected to the lens frame 111, and the lens frame 111 is detachably connected to the bezel assembly 120. The lens frame 111 and the bezel assembly 120 form a first through hole 151, through which a portion of the waveguide 140 is exposed. Therefore, the lens frame 111 has a semi-rimless structure. The lens frame 111 and the bezel assembly 120 cooperate to achieve a semi-rimless design for the smart glasses 100, which reduces the size of the smart glasses 100 and improves the user experience.

[0085] See also Figure 3 The system includes two frames 111 and two frame assemblies 120. The two frames 111 are connected via a bridge 112. Each frame 111 can be U-shaped and surrounds the edge of the upper half of the waveguide 140. Each frame assembly 120 corresponds to one frame 111 and is detachably connected to its corresponding frame 111. Additionally, each frame assembly 120 can be U-shaped and surrounds the edge of the lower half of the waveguide 140.

[0086] In some embodiments, the outer surface of the frame 111 can be made of metal, which allows for a high-gloss metallic design and helps to enhance the aesthetic appeal of the smart glasses 100.

[0087] For example, the frame 111 can be made of metal, which can reduce the manufacturing difficulty of the frame 111.

[0088] In other embodiments, the outer surface of the frame 111 may also be made of a non-metallic material, such as plastic.

[0089] Figure 4 for Figure 3 A cross-sectional view along the BB direction.

[0090] In some embodiments, see Figure 4The frame 111 may include a fourth groove 157, with a portion of the waveguide 140 located inside the fourth groove 157, and the waveguide 140 spaced apart from the frame 111. The smart glasses 100 may also include a third flexible member 160, at least a portion of which is located inside the fourth groove 157. For example, the entire third flexible member 160 may be located inside the fourth groove 157, or only a portion may be located inside the fourth groove 157. The third flexible member 160 contacts the inner wall of the fourth groove 157 and also contacts the waveguide 140. The third flexible member 160 is located within the gap between the frame 111 and the waveguide 140, and is configured to seal the gap between the frame 111 and the waveguide 140. This avoids hard contact between the frame 111 and the waveguide 140, and the third flexible member 160 acts as a stress buffer, preventing damage to the waveguide 140. In addition, the deformation of the third flexible element 160 can seal the edge of the waveguide 140, thus meeting the reliability requirements of the waveguide 140.

[0091] In some embodiments, see Figure 4 The frame 111 may include a panel 1111 and a frame 1112, which are stacked together. The panel 1111 is located in front of the frame 1112 in the front-back direction, and the panel 1111 and the frame 1112 may form a fourth groove 157.

[0092] It should be noted that the specific structure of the frame 111 is not limited to... Figure 4 The structure shown. Figure 4 The structure of the frame 111 is only used to illustrate its connection with the waveguide 140 and does not constitute a specific structural limitation on the frame 111. In addition, the front of the frame 1112 is the side of the frame 1112 that is furthest from the user's eyes in the front-back direction.

[0093] In some embodiments, the frame 1112 can be detachably connected to the frame 121. For example, the frame 1112 can be snapped into the frame 121 to achieve a detachable connection between the frame 111 and the frame 121.

[0094] In some embodiments, the third flexible element 160 may include, but is not limited to, foam, silicone, adhesive formed after the glue has cured, and backing adhesive.

[0095] In some embodiments, see also [link to previous document]. Figure 4 The third flexible member 160 may include a fifth groove 158, with a portion of the waveguide 140 located inside the fifth groove 158. Thus, the third flexible member 160 is similar to a U-shaped structure, which allows for sufficient filling of the gap between the waveguide 140 and the inner wall of the fourth groove 157, preventing accidental contact between the waveguide 140 and the frame 111.

[0096] It should be noted that the third flexible component 160 is, in addition to being Figure 4 Besides the structure shown, other structures are also possible, such as an L-shaped structure.

[0097] For example, see Figure 4 The frame assembly 120 may include a frame 121 and a first flexible member 122. The frame 121 is detachably connected to the lens frame 111, and the frame 121 and the lens frame 111 form a first through-hole 151 that exposes a portion of the waveguide 140. The frame 121 includes a first groove 154, and a portion of the waveguide 140 is located inside the first groove 154. The waveguide 140 and the frame 121 are spaced apart. At least a portion of the first flexible member 122 is disposed inside the first groove 154; for example, the entire first flexible member 122 may be located inside the first groove 154, or a portion of the first flexible member 122 may be disposed inside the first groove 154. The first flexible member 122 contacts the inner wall of the first groove 154 and contacts the waveguide 140. The first flexible member 122 is disposed within the gap between the frame 121 and the waveguide 140, and is configured to seal the gap between the frame 121 and the waveguide 140.

[0098] In this embodiment, by providing a first flexible member 122 in the gap between the frame 121 and the waveguide 140, direct contact between the waveguide 140 and the frame 121 is avoided, preventing hard contact between the two. The first flexible member 122 can act as a stress buffer, preventing damage to the waveguide 140. In addition, the first flexible member 122 is flexible and can deform, which can seal the gap between the waveguide 140 and the frame 121, meeting the reliability requirements of the waveguide 140.

[0099] See Figure 4 The frame 121 can be set around the lower half of the waveguide 140. The frame 121 is equivalent to the bottom of the existing eyeglass frame. However, the frame 121 is a one-piece structure, not composed of two structural parts. This allows the frame 121 to have a small thickness in the front-to-back direction and a small width in the vertical direction, achieving both narrow and thin frame designs. In this way, the eyeglass frame 111 can be a semi-frame design. After the frame 121 is connected to the eyeglass frame 111, the size of the smart glasses 100 can be reduced, the appearance can be improved, and the user experience can be enhanced.

[0100] For example, the first flexible member 122 can be fixedly connected to the frame 121, for instance, the first flexible member 122 can be bonded to the frame 121.

[0101] In some embodiments, the first flexible element 122 may include, but is not limited to, silicone, adhesive backing, foam, colloids formed by curing adhesive.

[0102] In some embodiments, when the first flexible element 122 is made of silicone, the first flexible element 122 and the frame 121 can be an integral structure. For example, the first flexible element 122 can be formed on the inner wall of the first groove 154 of the frame 121 using double-shot silicone technology.

[0103] In some embodiments, see also [link to previous document]. Figure 4 The first flexible member 122 may include a second groove 155, with a portion of the waveguide 140 located inside the second groove 155. The sidewalls and bottom of the second groove 155 are in contact with the waveguide 140. Therefore, the first flexible member 122 is similar to a U-shaped structure, which can fully fill the gap between the waveguide 140 and the inner wall of the first groove 154, preventing accidental contact between the waveguide 140 and the frame 121.

[0104] It should be noted that the first flexible component 122 is, in addition to being, Figure 4 Besides the structure shown, other structures are also possible, such as an L-shaped structure.

[0105] In some embodiments, the outer surface of the frame 121 can be made of metal, which allows the outer surface of the frame 121 to have a high-gloss design, helping to further improve the appearance and sophistication of the smart glasses 100.

[0106] For example, the frame 121 can be a metal frame. While achieving a high-gloss design, the frame 121 can also reduce the manufacturing difficulty of the frame 121. For example, the frame 121 can be manufactured by one-piece molding, such as stamping.

[0107] Of course, in addition to being made entirely of metal, in some examples, the frame 121 may include a non-metallic layer and a metal layer, with the metal layer and the non-metallic layer stacked together, and the outer surface of the metal layer being the outer surface of the frame 121.

[0108] Figure 5 This is a three-dimensional structural diagram of the border 121 provided in an embodiment of this application.

[0109] In some embodiments, see Figure 5 The frame 121 may include two second through holes 152, which are spaced apart in the left-right direction and are respectively located at the left and right ends of the frame 121. The second through holes 152 are configured to allow fasteners to pass through, such as screws. After passing through the second through holes 152, the fasteners are threadedly connected to the frame 111, thereby realizing a detachable connection between the frame 121 and the frame 111.

[0110] It should be noted that, in addition to being threaded to the frame 111, the fastener can also be detachably connected to the frame 111 in other ways, such as snapping it into the frame 111.

[0111] It should also be noted that, in addition to being detachably connected to the frame 111 indirectly through fasteners, in some examples, the frame 121 can also be directly connected to the frame 111, for example, the frame 121 can be snapped into the frame 111.

[0112] In some embodiments, see also [link to embodiment]. Figure 5 The frame 121 may include a first connecting portion 1211, a first arc-shaped portion 1212, and a second connecting portion 1213. The two ends of the first arc-shaped portion 1212 are fixedly connected to the first connecting portion 1211 and the second connecting portion 1213, respectively. The first arc-shaped portion 1212 includes a first groove 154. The first connecting portion 1211 and the second connecting portion 1213 are arranged at intervals in the left-right direction, and both the first connecting portion 1211 and the second connecting portion 1213 include a second through hole 152. In this way, the frame 121 can be detachably connected to the frame 111 via a fastener, ensuring the reliability of the connection between the frame 121 and the frame 111 while simplifying the structure of the frame 121.

[0113] It should be noted that the specific shape of border 121 is as follows: Figure 5 Besides the shape shown, other shapes are also possible. In addition, the specific shape of the border 121 can match the shape of the waveguide 140.

[0114] For example, the first connecting part 1211, the first arc-shaped part 1212 and the second connecting part 1213 are integrated into one structure, which can reduce the manufacturing difficulty of the frame 121 and improve the strength of the fixed connection between the first arc-shaped part 1212 and the first connecting part 1211 and the second connecting part 1213.

[0115] In one related technology, to meet the needs of nearsighted users wearing smart glasses, the nearsighted lens can be placed on the inside of the waveguide along the front-to-back direction and fixed to the inner cover plate of the waveguide by adhesive bonding. However, the solution of bonding the nearsighted lens to the waveguide is costly and can easily damage the waveguide during the replacement of the nearsighted lens.

[0116] In addition, for scenarios such as store demonstrations, after fixing the myopia lenses onto the waveguide, it can only meet the wearing needs of a small number of users with different myopia degrees, and cannot meet the trial wearing needs of users with other myopia degrees.

[0117] In related technology two, the myopia lens is fixed to a detachable clip bracket, which can engage with the bridge of the smart glasses, enabling a detachable connection between the myopia lens and the smart glasses. Alternatively, the myopia lens is fixed to a magnetic bracket, which can magnetically connect with magnets on the frame, thus securing the myopia lens. However, when the myopia lens is fixed to the frame using either a magnetic bracket or a clip bracket, the gap between the myopia lens and the waveguide is open to the external environment, and there is no sealed dustproof structure between the lens and the waveguide. After prolonged wear of the smart glasses, a significant amount of dust can easily accumulate on the surfaces of the waveguide and the myopia lens that are in close proximity. Therefore, the myopia lens needs to be removed for cleaning of both the lens and the waveguide to ensure the user's field of vision and viewing experience.

[0118] Therefore, using magnetic or snap-on brackets to fix prescription lenses to the frame presents a problem of sealing the waveguide and the lens to prevent dust, which will reduce the user experience. Furthermore, using magnetic or snap-on brackets to connect to the frame requires a snap-on structure on the bridge of the nose, which affects the appearance of the smart glasses. In addition, using magnetic or snap-on brackets to connect to the frame also results in cumbersome replacement, making it difficult to meet the needs of in-store demonstration scenarios.

[0119] Figure 6 The smart glasses 100 provided in this application embodiment Figure 3 A cross-sectional view along the BB direction. Figure 7 for Figure 6 A schematic diagram of a three-dimensional structure of the border component 120 after removing the first flexible component 122.

[0120] In some embodiments, see Figure 6 The smart glasses 100 may also include a corrective lens 170, which is disposed on the inner side of the frame 121 along the front-to-back direction and fixedly connected to the frame 121. The corrective lens 170 may be located between the waveguide 140 and the user's eye. The corrective lens 170 is configured to correct the user's vision; for example, the corrective lens 170 may be a myopia lens. Figure 6 and Figure 7 It is understood that the frame 121 may also include a third through-hole 153, which extends through the frame 121 along the thickness direction of the waveguide 140. The third through-hole 153 exposes a portion of the corrective lens 170 located inside the frame 121, allowing light to pass through. The corrective lens 170 covers the third through-hole 153. The frame assembly 120 also includes a second flexible member 123, which has an annular structure. The second flexible member 123 is located outside the first groove 154 and is disposed inside the gap between the corrective lens 170 and the frame 121. The second flexible member 123 is configured to seal the gap between the inner side of the frame 121 and the corrective lens 170.

[0121] For example, the thickness direction of waveguide 140 is parallel to the front-back direction of smart glasses 100. It should be noted that when two directions are parallel, the two directions can be absolutely parallel, or the angle between the two directions is less than 2°, which can also be considered as the two directions being parallel.

[0122] For example, the inner side of the border 121 can be understood as the side of the border 121 that is closer to the user's eyes in the front-back direction, and the outer side of the border 121 can be understood as the side of the border 121 that is farther away from the user's eyes in the front-back direction.

[0123] In some examples, the corrective lens 170 may be part of the frame assembly 120, meaning that the frame assembly 120 may include the corrective lens 170. Of course, in addition to being part of the frame assembly 120, in other examples, the corrective lens 170 and the frame assembly 120 may also be two relatively independent parts, in which case the corrective lens 170 and the frame assembly 120 may constitute a lens module.

[0124] See Figure 6 The first flexible component 122 can seal the gap between the waveguide 140 and the frame 121, and the second flexible component 123 can seal the gap between the inner side of the frame 121 and the corrective lens 170. This can prevent the gap between the waveguide 140 and the corrective lens 170 from being connected to the external environment, and prevent foreign objects such as dust in the external environment from entering the gap between the waveguide 140 and the corrective lens 170. After a period of time, there is no need to remove the myopia lens, and there is no need to clean the waveguide 140 and the myopia lens, which helps to improve the user experience.

[0125] In practical implementation, the frame 121 has a third through hole 153 and a third flexible member 160 (e.g. Figure 7 (As shown) can be available as a spare part; the smart glasses 100 can be shipped with, for example... Figure 5 The frame 121 is shown. If the user is nearsighted, the user can fix the nearsighted lens onto the frame 121 with the third through hole 153, then remove the frame 121 that comes with the smart glasses 100, and then fix the frame 121 with the nearsighted lens to the frame 111, so as to achieve the purpose of replacing the frame 121 by himself, so as to integrate the nearsighted lens into the smart glasses and meet the user's needs.

[0126] Since the myopia lens is fixed to the frame 121, it will not affect the waveguide 140, thus avoiding damage to the waveguide 140. In addition, due to the presence of the first flexible member 122 and the second flexible member 123, the gap between the waveguide 140 and the myopia lens can be sealed, achieving the purpose of waterproofing and dustproofing, and avoiding frequent cleaning of the waveguide 140 and the myopia lens.

[0127] In some embodiments, along a direction perpendicular to the thickness direction of waveguide 140 (e.g.) Figure 6 (in the Z direction), the minimum width of the second flexible member 123 (e.g.) Figure 6 (As shown in D) is greater than or equal to 0.8 mm. This ensures that the second flexible member 123 can seal the gap between the corrective lens 170 and the inner side of the frame 121, providing good reliability.

[0128] For example, the minimum width of the second flexible member 123 may include, but is not limited to, 0.85mm, 0.9mm, 1.0mm, etc.

[0129] In some embodiments, the second flexible element 123 may include an adhesive layer along the thickness direction of the waveguide 140 (e.g., Figure 6 (In the Y direction), one side of the adhesive layer is bonded to the frame 121, and the other side is bonded to the corrective lens 170. In this way, the second flexible member 123 not only seals the gap between the corrective lens 170 and the frame 121, but also fixes the corrective lens 170 to the frame 121, which can reduce the number of parts in the smart glasses 100 and simplify the structure of the smart glasses 100.

[0130] In some embodiments, see Figure 6 The first flexible member 122 may include an annular portion 1221 and a non-annular portion 1222. A portion of the annular portion 1221 is located inside the first groove 154, and another portion is located inside the first groove 154. The annular portion 1221 is configured to seal the frame 121 and the waveguide 140 in the thickness direction of the waveguide 140 (e.g.,...). Figure 6 An annular gap in the Y direction. The non-annular portion 1222 is fixedly connected to the annular portion 1221, and the non-annular portion 1222 is located inside the first groove 154. In this way, the first flexible member 122 can fully seal the gap between the frame 121 and the waveguide 140, which can further improve the sealing effect.

[0131] It should be noted that when the frame 121 is provided with a third through hole 153, in addition to being formed by the annular portion 1221 and the non-annular portion 1222, in some examples, the first flexible member 122 can also be without the non-annular portion 1222.

[0132] For example, see Figure 6 The non-annular portion 1222 and the annular portion 1221 can form a second groove 155, thereby fully sealing the gap between the waveguide 140 and the inner wall of the first groove 154.

[0133] For example, see Figure 6The non-annular portion 1222 can be an L-shaped structure. Of course, the non-annular portion 1222 can also have other structures; for example, the non-annular portion 1222 can be removed. Figure 6 The vertical portion on the left side of the middle section, the non-circular portion 1222 is formed by the horizontal portion.

[0134] In some embodiments, see Figure 6 The annular portion 1221 and the non-annular portion 1222 can be an integral structure. Of course, they can also be separate structures.

[0135] In some embodiments, along a direction perpendicular to the thickness direction of waveguide 140 (e.g.) Figure 6 (in the Z direction), the minimum width of the annular portion 1221 (e.g.) Figure 6 The diameter (H shown in the middle) is greater than or equal to 0.8 mm. This ensures that the first flexible element 122 can seal the gap between the waveguide 140 and the frame 121, resulting in good reliability.

[0136] For example, the minimum width of the annular portion 1221 may include, but is not limited to, 0.85mm, 0.9mm, 1.0mm, etc.

[0137] In some embodiments, see Figure 7 The frame 121 may include a first connecting portion 1211, a second connecting portion 1213, a first arc-shaped portion 1212, and a second arc-shaped portion 1214. The first connecting portion 1211 and the second connecting portion 1213 are arranged at intervals in the left-right direction, and are respectively connected to the two ends of the first arc-shaped portion 1212. The two ends of the first arc-shaped portion 1212 are respectively fixedly connected to the two ends of the second arc-shaped portion 1214, and the first arc-shaped portion 1212 forms a first groove 154. The second arc-shaped portion 1214 and the first arc-shaped portion 1212 form a third through hole 153.

[0138] For example, the second arc-shaped portion 1214 can be an arc-shaped flat plate structure. Of course, the second arc-shaped portion 1214 can also be other structures, such as an arc-shaped L-shaped flat plate structure.

[0139] Figure 8 An exploded view of another structure of the smart glasses 100 provided in this application embodiment.

[0140] In some embodiments, see Figure 8 The smart glasses 100 may also include two lens assemblies 200, each corresponding to a frame 111. The lens assembly 200 and the corresponding frame 111 are detachably connected. The lens assembly 200 is located inside the frame 111, which is the side of the frame 111 that is closer to the user's eyes in the front-back direction.

[0141] Figure 9 for Figure 8 A frontal view of the lens assembly 200. Figure 10 for Figure 8 The diagram shows a frontal view of the smart glasses 100.

[0142] See also Figure 9 The lens assembly 200 may include a corrective lens 170, an elastic element 220, and an annular frame member 210. The elastic element 220 is fixedly connected to the annular frame member 210, and the elastic element 220 is configured to abut against the frame 111 (e.g., Figure 10 (As shown). The annular frame member 210 is fitted onto and fixedly connected to the corrective lens 170, and is configured to be detachably connected to the frame 111. See also... Figure 10 One of the ring frame 210 and the mirror frame 111 includes a slot 240, and the other includes a buckle 230 that can be snapped into the slot 240.

[0143] It should be noted that when the smart glasses 100 has a lens assembly 200, the frame 121 is not fixedly connected to the corrective lens 170, the frame 121 does not have a third through hole 153, and the smart glasses 100 does not include a second flexible member 123. In other words, when the corrective lens 170 is connected to the frame 121, the smart glasses 100 does not include the lens assembly 200.

[0144] In the embodiments of this application, see Figure 10 The clip 230 can be snapped into the slot 240, allowing the lens assembly 200 to be detachably connected to the frame 111 via a snap-fit ​​mechanism. This enables quick replacement of the lens assembly 200, meeting the needs of rapid lens replacement in store demonstration scenarios and accommodating the trial wearing needs of users with different prescriptions. Furthermore, when the lens assembly 200 is connected to the frame 111, the elastic element 220 abuts against the frame 111, ensuring the lens assembly 200 is firmly fixed to the frame 111. This prevents accidental separation of the lens assembly 200 from the frame 111 when the smart glasses 100 shakes, thus improving the stability of the connection between the lens assembly 200 and the frame 111.

[0145] In some embodiments, see also [link to previous document]. Figure 9 The annular frame 210 may include a metal frame 211 and a pull cord 212. The metal frame 211 includes one of a buckle 230 and a slot 240. The metal frame 211 is fixedly connected to the elastic member 220, and both ends of the metal frame 211 are fixedly connected to both ends of the pull cord 212. The metal frame 211 and the pull cord 212 form an annular structure surrounding the corrective lens 170. In this way, the annular frame 210 can be matched with corrective lenses 170 of different shapes, which can meet the user's needs for changing corrective lenses 170.

[0146] For example, both ends of the metal frame 211 may be provided with snap-fit ​​holes, and both ends of the pull wire 212 are respectively snapped into the two snap-fit ​​holes, and both ends of the pull wire 212 are respectively snapped into the metal frame 211, so as to realize the detachable connection between the metal frame 211 and the pull wire 212.

[0147] For example, the pull line 212 may include fishing line, which helps to reduce the cost of the pull line 212.

[0148] In some embodiments, see Figure 10 The ring frame 210 includes a buckle 230, and the frame 111 includes a slot 240. In this way, there is no need to add parts to the frame 111, which can reduce the weight of the frame 111 and reduce the impact on the appearance of the frame 111.

[0149] In some embodiments, see Figure 10 The annular frame 210 may include multiple buckles 230, including a first buckle 231 and a second buckle 232, along the length direction of the frame 111 (e.g. Figure 10 In the X-direction, the first latch 231 and the second latch 232 are located on both sides of the corrective lens 170, and the elastic member 220 and the first latch 231 are located on the same side of the corrective lens 170. The frame 111 includes multiple slots 240, including a first slot 241 and a second slot 242. The first slot 241 is configured for the insertion of the first latch 231 of the annular frame member 210, and the second slot 242 is configured for the insertion of the second latch 232 of the annular frame member 210. In this way, there are connection structures between the annular frame member 210 and the frame 111 on both sides in the left-right direction, which can improve the connection reliability between the lens assembly 200 and the frame 111.

[0150] For example, the length direction of the frame 111 is parallel to the left-right direction.

[0151] Figure 11 for Figure 10 A diagram at point K. Figure 12 for Figure 10 A schematic diagram at point P in the middle.

[0152] In some embodiments, combined with Figure 11 and Figure 12 It is known that the first latch 231 and the second latch 232 have different structures. The outer side wall of the first latch 231 in the direction perpendicular to the thickness direction of the corrective lens 170 is an arc-shaped side wall. In this way, the difficulty of the first latch 231 being engaged or disengaged from the first latch slot 241 can be reduced, and the difficulty of separating or assembling the lens assembly 200 from the frame 111 can be reduced.

[0153] In some embodiments, the structure of the first slot 241 is adapted to the shape of the first buckle 231 (e.g., Figure 11 As shown), the structure of the second slot 242 is adapted to the shape of the second buckle 232 (as shown). Figure 12 (As shown). This helps to improve the firmness of the connection between the lens assembly 200 and the frame 111.

[0154] For example, see Figure 11 The first buckle 231 is a semi-circular flat plate structure, and the corresponding first slot 241 is a semi-circular groove.

[0155] For example, see Figure 12 The second buckle 232 has a triangular flat plate structure, and the corresponding second slot 242 is a triangular groove.

[0156] In some embodiments, see Figure 11 The elastic element 220 may include a metal spring sheet, which can reduce the manufacturing difficulty of the elastic element 220.

[0157] Of course, the elastic element 220 can be made of other structures besides metal springs, such as elastic structures made of metallic and non-metallic materials.

[0158] The connection method between the elastic element 220 and the annular frame 210 may include, but is not limited to, welding, bonding, snap-fitting, etc.

[0159] In some embodiments, see Figure 11 The frame 111 may also include a third groove 156, which is configured to allow partial insertion of the elastic member 220. This reduces the influence of the elastic member 220 on the size of the gap between the frame 111 and the annular frame member 210, helping to keep the gap between the annular frame member 210 and the frame 111 small.

[0160] In some embodiments, one of the groove sidewalls of the third groove 156 is an inclined sidewall (e.g., Figure 11 As shown in the middle (T), the inclined sidewall is configured to guide the elastic member 220 away from the interior of the third groove 156. In this way, during the separation of the lens assembly 200 from the frame 111, the elastic member 220 can be prevented from abutting against the inner wall of the third groove 156, ensuring that the elastic member 220 can leave the third groove 156.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal connection of two components or the interaction between two components.
