[0060] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0061] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0062] It should be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0063] It will also be understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0064] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0065] As shown in FIG1 , the temples of most smart glasses are made of plastic. Therefore, the temples of the smart glasses are all hard and cannot be bent, which results in the temples being unable to adapt to the wearer's head shape and unable to form a wrapping effect on the wearer's head shape, resulting in poor wearing stability and comfort.

[0066] To address the shortcomings of the above-mentioned prior art, the present application proposes a pair of smart glasses. The temples of the smart glasses are flexible, allowing them to bend into a curved surface and deform according to the wearer's head size and shape. This allows the smart glasses to adapt to different head shapes and wrap around the wearer's head, thereby improving wearing stability and comfort.

[0067] Exemplarily, the smart glasses may be AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, or any other electronic device that can be used for AR imaging, such as smart wearable devices such as smart helmets, without specific limitation herein.

[0068] Please refer to Figures 2 and 3. Figure 2 is a structural diagram of a pair of smart glasses provided in an embodiment of the present application; Figure 3 is a structural diagram of another pair of smart glasses provided in an embodiment of the present application.

[0069] As shown in Figures 2 and 3, the smart glasses 100 include a display module 10, a frame module 20, and a battery module 30. The display module 10 may include an optomechanical assembly 12 and a waveguide assembly 11. The waveguide assembly 11 is used to receive display light emitted by the optomechanical assembly 12 and form output light. Specifically, the waveguide assembly 11 is provided with a waveguide substrate, an incoupling grating region, and an outcoupling grating region. The optomechanical assembly 12 is connected to the frame assembly 21 and is arranged corresponding to the incoupling grating region. The incoupling grating region and the outcoupling grating region may be provided on the waveguide substrate. The incoupling grating region is used to couple light into the waveguide substrate, and the outcoupling grating region is used to couple light propagating within the waveguide substrate out. Light emitted by the optomechanical assembly 12 will be incident on the incoupling grating region. After being diffracted by the incoupling grating region, the light can be totally reflected within the waveguide substrate, thereby being transmitted laterally within the waveguide assembly 11 until it is diffracted again by the outcoupling grating region and reaches the human eye for imaging.

[0070] Exemplarily, the coupling-in grating region and the coupling-out grating region may also be arranged on different surfaces of the waveguide substrate, for example, the coupling-in grating region is arranged on the first surface of the waveguide substrate, and the coupling-out grating region is arranged on the second surface of the waveguide substrate, or the coupling-out grating region is arranged on the first surface of the waveguide substrate, and the coupling-in grating region is arranged on the second surface of the waveguide substrate. As long as the coupling-in grating region can be used to couple light into the waveguide substrate, and the coupling-out grating region can be used to couple out light propagating in the waveguide substrate, it will be sufficient.

[0071] The frame module 20 includes a frame assembly 21 and a temple assembly 22 connected to the frame assembly 21. The frame assembly 21 is connected to the waveguide assembly 11, and the optical-mechanical assembly 12 and the waveguide assembly 11 are both mounted on the frame assembly 21. The temple assembly 22 includes a temple and a flexible connector disposed within the temple. A battery module 30 is connected to the temple end away from the frame assembly 21 and is electrically connected to the optical-mechanical assembly 12 via the flexible connector.

[0072] The flexible connector may be a flexible circuit connector, such as a flexible printed circuit (FPC) or a bendable electrical component such as a flexible wire. The flexible connector is used to electrically connect the battery module 30 to the optomechanical assembly 12, so that the battery module 30 disposed at the end of the temple can power the optomechanical assembly 12 through the flexible connector inside the temple.

[0073] In the prior art, smart glasses typically require a cavity within the temple to house electronic components. To avoid damaging these components, they are typically non-bendable. Therefore, the temples of smart glasses in the prior art are typically rigid and non-bendable.

[0074] As shown in Figures 2 and 3, the embodiment of the present application can avoid placing electronic components inside the temples by setting components such as the optical-mechanical component 12 and the waveguide component 11 on the frame component 21, and setting the battery module 30 at the end of the temples, and by setting flexible connectors inside the temples, the temples are made flexible, the temples can be bent into a curved surface, and the temples can be deformed according to the size and shape of the wearer's head, so that the smart glasses 100 can adapt to the head shapes of different wearers, and can form a wrapping effect on the wearer's head shape, thereby improving wearing stability and wearing comfort.

[0075] In some embodiments, the flexible connector may include a flexible printed circuit board, thereby enabling electrical connection between the battery module 30 and the opto-mechanical assembly 12 via a highly reliable and excellent flexible printed circuit board.

[0076] Flexible printed circuit boards (FPCs) are highly reliable and flexible printed circuit boards made from polyimide or polyester film. They feature high wiring density, light weight, thin thickness, and good bendability.

[0077] Since the flexible printed circuit board has the characteristics of high wiring density, light weight, thin thickness, and good bendability, it can be used as an electrical connection medium between the battery module 30 and the optical machine component 12. At the same time, the flexible printed circuit board is also set in the temple. As long as the temple is also made of flexible material, the temple assembly 22 can be made flexible, so that the temple can be deformed according to the wearer's head size and shape.

[0078] As shown in FIG4 , in some embodiments, a receiving groove 221 is formed in the temple 222, and the flexible printed circuit board is received in the receiving groove 221 and closely fits the receiving groove 221. Thus, the receiving groove 221 can be formed in the temple 222 by injection molding, the flexible printed circuit board is received in the receiving groove 221, and the flexible printed circuit board and the temple 222 are embedded together with plastic, so that the injection-molded temple 222 has high reliability and is easy to mass-produce.

[0079] For example, the temples 222 and the flexible printed circuit board can be sealed and bonded with soft skin-friendly materials such as silicone and rubber by in-mold injection molding, so that the injection-molded temples 222 have the effects of being waterproof, dustproof, sweat-proof, and easy to bend.

[0080] For example, the flexible printed circuit board and the titanium alloy temple 222 can also be formed in the form of an FPC reinforcement plate, and the flexible printed circuit board, the temple 222 and the FPC reinforcement plate can be integrally formed by dispensing or hot pressing.

[0081] In some embodiments, the flexible printed circuit board mounted in the temple 222 can be sealed and molded by in-mold injection molding to form the temple assembly 22. Thus, the flexible printed circuit board and the temple 222 can be embedded together by in-mold injection molding, making the injection-molded temple 222 more reliable and easier to mass-produce.

[0082] Specifically, the temples 222 and the flexible printed circuit board are sealed together using in-mold injection molding with soft, skin-friendly materials such as silicone and rubber. This makes the molded temples 222 waterproof, dustproof, sweat-resistant, and easily bendable. Once the temples 222 and the flexible printed circuit board are integrally molded, the temples 222 can still be adjusted in width and curvature to suit the wearer's face, significantly enhancing wearing comfort. Furthermore, the silicone used in the in-mold injection molding process is not easily dislodged, ensuring a comfortable touch at the contact surface between the temples 222 and the face.

[0083] For example, the metal temples 222 and the flexible printed circuit board can be used as inserts to be installed in the mold, and the injection molding parameters, such as temperature, pressure, time, etc., can be set. Then, soft skin-friendly materials such as silicone and rubber are added to the injection molding material. The injection molding machine is started, and the molten soft skin-friendly material is injected into the mold for in-mold injection molding. After the injection molding is completed, the injected silicone is now integrated with the temples 222, and the flexible printed circuit board is sandwiched between the silicone and the temples 222. The mold and the injection molded part are cooled to room temperature, and the injection molded part is removed from the mold. The injection molded part removed from the mold is the temple assembly 22.

[0084] In some embodiments, the temple 222, the flexible printed circuit board, and the reinforcement plate can be pressed together by dispensing glue or hot pressing to form the temple assembly 22. In this way, the flexible printed circuit board and the temple 222 can be embedded together by means of the FPC reinforcement plate, thereby highlighting the metallic texture of the temple 222 and making the injection-molded temple 222 more reliable.

[0085] Specifically, the flexible printed circuit board and the titanium alloy temple 222 can also be formed in the form of an FPC reinforcement plate, and the temple 222, the flexible printed circuit board and the reinforcement plate are pressed together by dispensing or hot pressing to form the temple assembly 22. The one-piece temple assembly 22 will be presented in the form of the titanium alloy facing outward (i.e., the side away from the wearer's head) and the flexible printed circuit board facing inward (i.e., the side close to the wearer's head). In this way, the metallic texture of the titanium alloy temple 222 can be highlighted, and the flexible printed circuit board on the inside can be brushed with glue to make the temple 222 waterproof, sweat-proof, dust-proof, skin-friendly and other effects. This FPC reinforcement plate bonding method can further compress the space of the temple 222, while also ensuring that the temple 222 can be flexibly adjusted for bending and forming.

[0086] It should be noted that the surface glue can be made of soft, skin-friendly materials such as silicone and rubber. Alternatively, the temples 222, the flexible printed circuit board, and the soft, skin-friendly materials such as silicone and rubber can be sealed and bonded together using in-mold injection molding, so that the molded temples 222 are waterproof, dustproof, sweat-proof, and easy to bend. Alternatively, a silicone or rubber sleeve can be installed on the side of the temples 222 closest to the wearer's head for assembly, so that the temples 222 equipped with the silicone or rubber sleeves can also be waterproof, dustproof, sweat-proof, and easy to bend.

[0087] As shown in FIG5 , in some embodiments, the temple assembly 22 further includes a flexible member 223, the flexible member 223 including a first connecting portion 224, and the temple 222 including a second connecting portion 225. The flexible member 223 is engaged with the temple 222 via the first connecting portion 224 and the second connecting portion 225 to seal the flexible connector 220. This facilitates removal and replacement of the flexible member 223, and prevents yellowing of the flexible member 223 due to prolonged wear of the smart glasses 100.

[0088] The flexible member 223 may be a component made of a flexible, skin-friendly material such as a molded silicone strip or a rubber strip.

[0089] Specifically, the flexible member 223 includes a first connecting portion 224, and the temple 222 includes a second connecting portion 225. The first connecting portion 224 can cooperate with the second connecting portion 225 to achieve the snapping of the flexible member 223 onto the temple 222. Simultaneously, the flexible connector 220 can be attached to the side of the temple 222 that includes the second connecting portion 225. This allows the first connecting portion 224 and the second connecting portion 225 to cooperate, sandwiching the flexible connector 220 between the flexible member 223 and the temple 222, thereby sealing the flexible connector 220 to form the temple assembly 22.

[0090] Exemplarily, the flexible connector 220 can be pre-attached to one side of the temple 222 including the second connecting portion 225 by means of glue or dispensing, so that when the first connecting portion 224 and the second connecting portion 225 cooperate with each other, the flexible connector 220 can be clamped between the flexible portion 223 and the temple 222.

[0091] It should be noted that the flexible member 223 may include a plurality of first connecting portions 224, and the temple 222 may include a plurality of second connecting portions 225. Each first connecting portion 224 corresponds to a second connecting portion 225, so that each first connecting portion 224 cooperates with its corresponding second connecting portion 225, thereby improving the coordination stability, sandwiching the flexible connector 220 between the flexible member 223 and the temple 222, and improving the fit between the flexible member 223 and the temple 222.

[0092] In some embodiments, the first connection portion 224 includes a groove, and the second connection portion 225 includes a raised portion, which is formed on the surface of the temple 222 by in-mold injection molding. This facilitates the removal and replacement of the flexible member 223, avoids the problem of yellowing of the flexible member 223 due to long-term wear of the smart glasses 100, and provides users with the functionality of removing and customizing the flexible member 223.

[0093] The protrusions may be plastic protrusions, which may be formed by injection molding or the like.

[0094] As shown in FIG5 , specifically, the first connecting portion 224 may include a groove, and the second connecting portion 225 may include a protrusion. When the first connecting portion 224 and the second connecting portion 225 engage with each other, the protrusion is inserted into the corresponding groove, thereby achieving a snap fit between the protrusion and the corresponding groove. After the protrusion and the corresponding groove are snap-fitted, the flexible connector 220 can be sandwiched between the flexible member 223 and the temple 222, thereby sealing the flexible connector 220 to form the temple assembly 22.

[0095] For example, a raised portion can be formed on the surface of the temple 222 close to the wearer through in-mold injection molding; then a corresponding groove can be formed in the flexible member 223 to cooperate with the raised portion, thereby achieving a mechanical snap-fit ​​structure to connect the temple 222, the flexible connector 220, and the flexible member 223. This facilitates the removal and replacement of the flexible member 223, avoids the problem of yellowing of the flexible member 223 due to long-term wear of the smart glasses 100, and provides users with the functionality of removing and customizing the flexible member 223.

[0096] For example, since the flexible member 223 is made of a flexible material, when the user needs to replace the flexible member 223 , the user can remove the flexible member 223 by external force, thereby achieving replacement of the flexible member 223 and improving the user's wearing experience.

[0097] In some embodiments, the second connection portion 225 includes a groove, and the first connection portion 224 includes a raised portion, which is formed on the surface of the flexible member 223 by in-mold injection molding. This provides another snap-fit ​​structure, while facilitating the removal and replacement of the flexible member 223, preventing the yellowing of the flexible member 223 due to prolonged wear of the smart glasses 100, and providing users with the functionality to remove and customize the flexible member 223.

[0098] Specifically, the first connecting portion 224 may include a protrusion, and the second connecting portion 225 may include a groove. When the first connecting portion 224 and the second connecting portion 225 are engaged with each other, the protrusion is inserted into the corresponding groove, thereby achieving a snap fit between the protrusion and the corresponding groove. After the protrusion and the corresponding groove are snap-fitted, the flexible connector 220 can also be sandwiched between the flexible member 223 and the temple 222, thereby sealing the flexible connector 220 to form the temple assembly 22.

[0099] For example, a raised portion can be formed on the flexible member 223 through in-mold injection molding; then a corresponding groove can be formed on the surface of the temple 222 close to the wearer to cooperate with the raised portion, thereby achieving a mechanical snap-fit ​​structure to connect the temple 222, the flexible connector 220, and the flexible member 223. This facilitates the removal and replacement of the flexible member 223, avoids the problem of yellowing of the flexible member 223 due to long-term wear of the smart glasses 100, and provides users with the functionality of removing and customizing the flexible member 223.

[0100] It should be noted that if the flexible member 223 includes a plurality of first connecting portions 224 and the temple 222 includes a plurality of second connecting portions 225, each groove portion has a corresponding protrusion portion, so that each groove portion and its corresponding protrusion portion can achieve a snap fit, thereby improving the fit stability, being able to clamp the flexible connector 220 between the flexible member 223 and the temple 222, and improving the fit between the flexible member 223 and the temple 222.

[0101] In some embodiments, the material of the temple 222 includes flexible metal or flexible sheet material, thereby making the temple 222 itself flexible, thereby achieving curved bending.

[0102] Flexible metals may include memory metals, which can undergo plastic deformation within a certain temperature range and then return to their original macroscopic shape within another temperature range. Memory metals may include copper-based memory alloys, nickel-titanium alloys, iron-based alloys, cobalt-based alloys, and titanium-based alloys. Flexible sheet materials may include metal sheets or soft plastic sheets, as long as the sheet material can be flexibly bent.

[0103] In some embodiments, the installation position of the battery module 30 on the temple 222 is determined based on the weight of the battery module 30, the weight of the display module 10, and the weight of the frame assembly 21. This allows the temple 222 to be balanced at both ends, thereby balancing the center of gravity of the smart glasses 100 and reducing the discomfort caused by the downward pressure of the nose pads on the nose bridge.

[0104] The battery module 30 can be installed anywhere on the temple 222, and the battery module 30 does not need to be installed inside the temple 222. Instead, it is installed on the temple 222 by dispensing glue. Therefore, the installation of the battery module 30 does not affect the flexibility of the temple 222, and the temple 222 can still deform according to the wearer's head size and shape. At the same time, the battery module 30 is connected to the flexible connector 220, and is electrically connected to the optical-mechanical assembly 12 through the flexible connector 220, thereby providing power to the optical-mechanical assembly 12 and other components.

[0105] Specifically, the installation position of the battery module 30 on the temple 222 can be determined based on the weight of the battery module 30, the weight of the display module 10, and the weight of the frame assembly 21. Since the embodiment of the present application sets the battery module 30 at the tail end of the temple 222, and sets the display module 10 and the frame assembly 21 at the front end of the temple 222, and the positions of the display module 10 and the frame assembly 21 are generally fixed, the installation position of the battery module 30 on the temple 222 can be adjusted by the lever principle so that the front and rear ends of the temple 222 are balanced, thereby balancing the center of gravity of the smart glasses 100 and improving the wearing comfort of the user.

[0106] Since most components of the current smart glasses 100, such as the nose pads, chips, sensors, and batteries, are integrated into the frame or the top of the glasses, the frame portion of the smart glasses 100 is heavy, especially the battery, which leads to an imbalance in the weight of the front and back of the glasses, making them uncomfortable for the wearer. However, the embodiment of the present application arranges the battery module 30 at the end of the temple 222 and the display module 10 and frame assembly 21 at the front end of the temple 222. While ensuring that the temple 222 is flexible, it can also achieve a balance between the front and back ends of the temple 222, thereby balancing the center of gravity of the smart glasses 100, reducing the discomfort caused by the downward pressure of the nose pads on the nose bridge, and improving the wearing comfort of the user.

[0107] In some embodiments, the installation position of the battery module 30 on the temple 222 is determined based on the position of the wearer's ear. As a result, the battery module 30 can be placed behind the wearer's ear, thereby effectively hiding the battery module 30 behind the ear and visually increasing the lightness of the smart glasses 100 when worn.

[0108] For example, if the wearer's ears are positioned backward, the battery module 30 is positioned backward of the temple 222; if the wearer's ears are positioned forward, the battery module 30 is positioned forward of the temple 222. Thus, the battery module 30 can be positioned behind the ear to match the ear position. This allows the battery module 30 to be positioned behind the ear. When the smart glasses 100 are worn normally, the ear can be used to block vision, effectively hiding the battery module behind the ear and visually increasing the ease of wearing the glasses.

[0109] In this embodiment, the battery module 30 is installed on the temple 222 according to the wearer's ear position. By utilizing the visual principle of the battery module 30 being placed behind the ear, the ear can be used to block vision, making the smart glasses 100 more lightweight and simple to wear.

[0110] As shown in FIG6 , in some embodiments, the temples 222 are further configured to bend in a first direction at a predetermined curvature, so that the ends of the temples 222 away from the frame assembly 21 form ear hooks 226. The ear hooks 226 are configured to conform to the shape of the wearer's ears to secure the glasses. Thus, the ear hook design of the smart glasses 100 can increase overall wearing stability, conforming to the wearer's ear shape to secure the glasses, thereby increasing the wearing stability of the smart glasses 100.

[0111] The first direction is a direction perpendicular to the temple 222, that is, the direction in which the wearer stands. The preset curvature can be determined according to the shape of the wearer's ear and can be any curvature, which is not specifically limited here.

[0112] Specifically, since the wearer's ears are generally located at the end of the temple 222, the bending starting point of the ear hook 226 can be set at the end of the temple 222 according to the wearer's ear shape and ear position, and the temple 222 can be bent according to a preset arc.

[0113] In the embodiment of the present application, an ear hook portion 226 that conforms to the wearer's ear shape can be provided at the end of the temple 222. The glasses can be fixed in place according to the wearer's ear shape, thereby increasing the wearing stability of the smart glasses 100.

[0114] As shown in FIG6 , in some embodiments, the battery module 30 can be disposed on the ear hook portion 226. This design of the ear hook with the battery module 30 disposed behind the smart glasses 100 can further enhance the wearing stability of the smart glasses 100, and the glasses can be fixed in place by fitting the shape of the wearer's ears, thereby enhancing the wearing stability of the smart glasses 100.

[0115] The battery module 30 can be installed in the ear hook portion 226 of the temple 222. The battery module 30 does not need to be installed inside the temple 222, but is installed on the ear hook portion 226 by dispensing glue. Therefore, the installation of the battery module 30 does not affect the flexibility of the temple 222, and the temple 222 can still deform according to the wearer's head size and shape. At the same time, the battery module 30 is connected to the flexible connector 220, and is electrically connected to the optical-mechanical assembly 12 through the flexible connector 220, thereby providing power to the optical-mechanical assembly 12 and other components.

[0116] Specifically, by arranging the battery module 30 in the ear hook portion 226, the wearing discomfort caused by the downward pressure of the nose pad on the nose bridge is reduced. At the same time, the ear hook design with the battery pack placed behind can increase the friction between the silicone on the temple 222 and the ear contact surface. Moreover, due to the wrapping effect of the flexible temple on the head, the contact area and friction between the battery module 30 and the head can also be increased, thereby further increasing the wearing stability of the glasses.

[0117] In some embodiments, the angle corresponding to the preset arc is determined based on the wearer's ear shape and ear position. Thus, the angle corresponding to the preset arc can be determined based on the wearer's ear shape and ear position, thereby enabling the ear hook 226 to better fit the wearer's ear and head, improving wearing stability and comfort.

[0118] The included angle corresponding to the preset arc can be any angle, such as 150°, and is not specifically limited here.

[0119] As shown in FIG7 , the temple 222 is further configured to bend in a first direction at a predetermined curvature to form an ear hook portion 226 at one end of the temple 222 away from the frame assembly 21. The predetermined curvature may correspond to an angle of 150°, which may be determined based on the shape and position of the wearer's ears.

[0120] In some embodiments, the angle corresponding to the preset curvature is greater than or equal to 150° and less than or equal to 180°. Since the adjustable temples 222 are used to wrap around the sides of the head, the bending amplitude of the ear hooks 226 can be reduced, that is, the angle corresponding to the preset curvature is increased, thereby avoiding affecting the wearing of the smart glasses 100. At the same time, the smart glasses 100 can be adapted to the head shapes and ear positions of more wearers.

[0121] As shown in FIG8(a), to improve the wearing stability of the smart glasses 100, it is generally necessary to reduce the bending amplitude of the ear hook 226, that is, the angle corresponding to the preset curvature, so that the ear hook 226 can better fit the wearer's ear and achieve wearing stability. However, if the angle corresponding to the preset curvature is small, for example, the angle corresponding to the preset curvature is within the range of 90° to 140°, the bending amplitude of the ear hook 226 is large, and the ear hook 226 of the smart glasses 100 is raised to a large height, which affects the wearability of the smart glasses 100 and may even cause the wearer to experience dizziness.

[0122] As shown in FIG8( b ), the embodiment of the present application can utilize adjustable temples 222 to wrap around the side of the head. In this case, the bending amplitude of the ear hook 226 does not need to be too large to achieve stable wearing. This can reduce the bending amplitude of the ear hook 226, that is, increase the angle corresponding to the preset arc. For example, the angle corresponding to the preset arc can be within the range of 150° to 180°. In this case, the bending amplitude of the ear hook 226 is small, and the ear hook 226 of the smart glasses 100 is lifted to a small height, which basically does not affect the wearing of the smart glasses 100. At the same time, it can also enable the smart glasses 100 to adapt to the head shape and ear position of more wearers.

[0123] In some embodiments, the smart glasses 100 further include a counterweight module connected to the end of the temple 222 away from the frame assembly 21. The counterweight module is used to balance the ends of the temple 222. Thus, in situations where simply installing the battery module 30 on the temple 222 would not achieve balance at both ends of the temple 222, the counterweight module can achieve balance at both ends of the temple 222, thereby reducing the discomfort caused by the downward pressure of the nose pads on the nose bridge and improving wearing comfort.

[0124] If the weight of the display module 10 and the weight of the frame assembly 21 are much greater than the weight of the battery module 30, then if the battery module 30 is only set at the temple 222, it is still impossible to achieve balance at both ends of the temple 222. At this time, a counterweight module needs to be set on the temple 222 to achieve balance at both ends of the temple 222.

[0125] Specifically, by installing a counterweight module at the end of the temple 222 away from the frame assembly 21, the battery module 30 and the counterweight module can provide more downward pressure at the rear end of the glasses to balance the pressure at the front end of the glasses, thereby further solving the problem of high downward pressure on the nose pads. By forming a balancing lever with the ear fulcrum, the increased downward pressure at the rear end of the temple 222 helps reduce the downward pressure on the nose pads, allowing the wearer to wear the smart glasses 100 for a long time without forming an indentation on the nose bridge.

[0126] In some embodiments, if the weight of the counterweight module is fixed, the installation position of the counterweight module on the temple 222 is determined based on the weight of the battery module 30, the weight of the display module 10, and the weight of the frame assembly 21. Thus, when the weight of the counterweight module is fixed, the installation position of the counterweight module on the temple 222 can be adjusted to achieve balance between the front and rear ends of the temple 222, thereby balancing the center of gravity of the smart glasses 100 and improving the wearing comfort of the user.

[0127] The counterweight module can be installed anywhere on the temple 222, and it does not need to be installed inside the temple 222. Instead, it can be installed on the temple 222 by dispensing glue or magnetic attraction. Therefore, the installation of the counterweight module does not affect the flexibility of the temple 222, and the temple 222 can still deform according to the wearer's head size and shape. At the same time, the battery module 30 is connected to the flexible connector 220, and is thereby electrically connected to the optical-mechanical assembly 12 through the flexible connector 220, thereby providing power to the optical-mechanical assembly 12 and other components.

[0128] Specifically, if the weight of the counterweight module is fixed, by setting the battery module 30 and the counterweight module at the tail end of the temple 222, and setting the display module 10 and the frame assembly 21 at the front end of the temple 222, and on the premise that the temple 222 is flexible, the specific position of the counterweight module on the temple 222 is adjusted using the lever principle, so that the front and rear ends of the temple 222 can be balanced, thereby balancing the center of gravity of the smart glasses 100, reducing the wearing discomfort caused by reducing the downward pressure of the nose pad on the nose bridge, and improving the wearing comfort of the user.

[0129] In some embodiments, if the counterweight module is fixedly mounted on the temple 222, the weight of the counterweight module is determined based on the weight of the battery module 30, the weight of the display module 10, and the weight of the frame assembly 21. Thus, when the counterweight module is fixedly mounted on the temple 222, the weight of the counterweight module can be adjusted to achieve balance between the front and rear ends of the temple 222, thereby balancing the center of gravity of the smart glasses 100 and improving the wearing comfort of the user.

[0130] The weight module can be disposed on the ear hanging portion 226 of the temple 222 by means of magnetism or the like, and the weight module and the battery module 30 can be disposed together on the ear hanging portion 226 of the temple 222 .

[0131] Specifically, if the installation position of the counterweight module on the temple 222 is fixed, by setting the battery module 30 and the counterweight module at the tail end of the temple 222, and setting the display module 10 and the frame assembly 21 at the front end of the temple 222, and under the premise of making the temple 222 flexible, the weight of the counterweight module is adjusted using the lever principle, so that the front and rear ends of the temple 222 can be balanced, thereby balancing the center of gravity of the smart glasses 100, reducing the wearing discomfort caused by reducing the downward pressure of the nose pad on the nose bridge, and improving the wearing comfort of the user.

[0132] In some embodiments, the smart glasses 100 include a main control module, which is electrically connected to the battery module 30 and is used to control the light-generating light of the optical-mechanical assembly 12. Thus, the battery module 30 can be used to power the main control module, thereby controlling the light-generating light of the optical-mechanical assembly 12.

[0133] Among them, the main control module can be a PCBA board, which refers to a product that solders integrated circuits, surface mount components and other electronic components on a PCB board to realize circuit functions.

[0134] For example, the main control module can be set at the end of the temple 222 by dispensing glue or the like, or can be set in the frame assembly 21. The position of the main control module is not specifically limited here.

[0135] In some embodiments, the main control module is disposed at one end of the temple 222 away from the frame assembly 21, and the main control module is connected to the optical-mechanical assembly 12 via a flexible connector 220. Thus, the main control module can also be disposed at the end of the temple 222, thereby further reducing the volume and weight of the front end of the glasses, achieving a balance between the front and rear ends of the temple 222, and thus balancing the center of gravity of the smart glasses 100, reducing the discomfort caused by the downward pressure of the nose pads on the nose bridge, and improving the wearing comfort of the user.

[0136] Specifically, the main control module can also be installed at the end of the temple 222 away from the frame assembly 21 by dispensing glue, etc., and the main control module can be connected to the optical-mechanical assembly 12 via the flexible connector 220, thereby controlling the optical-mechanical assembly 12 to emit light. If the main control module and the battery module 30 are not integrally arranged, the main control module can also be electrically connected to the battery module 30 via the flexible connector 220, so that the battery module 30 provides power to the main control module.

[0137] In some embodiments, the battery module 30 and the main control module are relatively fixed or integrated, thereby further reducing the overall volume of the smart glasses 100.

[0138] If the main control module and the battery module 30 are not integrated, a shell for accommodating the main control module and a shell for accommodating the battery module 30 need to be respectively provided at the end of the temple 222 away from the frame assembly 21, which will cause the overall volume of the smart glasses 100 to be larger.

[0139] Specifically, the main control module can be disposed within the battery module 30 so that the battery module 30 and the main control module are relatively fixed or integrally disposed. In this case, the main control module does not need to be electrically connected to the battery module 30 via the flexible connector 220. The battery module 30 can be directly connected to the main control module and power the main control module.

[0140] In the embodiment of the present application, the battery module 30 and the main control module are relatively fixed or integrated, thereby further reducing the overall volume of the smart glasses 100 and achieving a lightweight design of the smart glasses 100.

[0141] In some embodiments, the smart glasses 100 include a sensor module, which is located at the end of the temple 222 away from the frame assembly 21. The sensor module is electrically connected to the battery module 30 via the flexible connector 220 and is also used to detect the wearer's physical condition. By arranging the sensor module at the end of the temple 222, the sensor module can better fit the user's head and skin, thereby more accurately detecting the wearer's physical condition in real time.

[0142] Among them, the sensor module can include blood oxygen sensors, heart rate sensors, brain wave sensors and other sensors for measuring different health indicators of users.

[0143] Exemplarily, the sensor module can be separately provided at one end of the temple 222 away from the frame assembly 21 and electrically connected to the main control module and the battery module 30 through the flexible connector 220, thereby realizing real-time detection of the wearer's physical condition.

[0144] For example, the sensor module can be placed together with the main control module and arranged at the end of the temple 222 away from the frame assembly 21. The sensor module can be electrically connected to the battery module 30 via the flexible connector 220, and the sensor module and the main control module are arranged together, so that the sensor module is closer to the main control module, the delay of the sensor module is reduced, and the response is faster.

[0145] For example, the sensor module and the main control module can be set in the battery module 30. This can achieve an integrated setting of the sensor module, the main control module and the battery module 30, which can reduce the volume of the smart glasses 100. The sensor module can better fit the user's head and skin, thereby being able to more accurately detect the wearer's physical condition in real time.

[0146] Since the frame assembly 21 generally does not fit the user's head and skin, if the sensor module is placed on the frame assembly 21, the sensor module cannot contact the user's head and skin, resulting in low sensor module detection accuracy. However, since the ends of the temples 222 generally fit the user's head and skin, in the example of this application, the sensor module is placed at the ends of the temples 222, which allows the sensor module to better fit the user's head and skin, thereby more accurately detecting the wearer's physical condition in real time.

[0147] As shown in FIG9 , in some embodiments, the frame assembly 21 includes a lens mount 210 and a temple connector 211 connected to the temple assembly 22 and the lens mount 210. The waveguide assembly 11 is connected to a side of the lens mount 210 away from the temple connector 211. Thus, the temple assembly 22 and the waveguide assembly 11 can be connected via the lens mount 210 and the temple connector 211, allowing the smart glasses 100 to be assembled without requiring a frame or mounting accessories, thereby enabling multiple components of the smart glasses 100 to be integrally formed.

[0148] The lens mounting member 210 may include a corresponding lens mounting frame, and the waveguide assembly 11 may be mounted in the lens mounting frame. The temple connector 211 may be used to connect the lens mounting member 210 and the temple assembly 22 .

[0149] Specifically, the lens mounting member 210 and the temple connector 211 in the frame assembly 21 can cooperate with each other, and the connection between the temple assembly 22 and the waveguide assembly 11 can be completed without setting mounting accessories for the frame and the pile head, thereby making multiple components in the smart glasses 100 integrally formed.

[0150] For example, the housings of components such as the lens mounting member 210, temple connector 211, and the optomechanical assembly 12 are formed from a single die-cast metal, thereby enabling the integration of multiple components within the smart glasses 100. Compared to traditional glasses that require mounting accessories such as frames and mounting posts for installation, this embodiment of the present application eliminates the need for these mounting accessories. Furthermore, the frame assembly 21 also accommodates components such as the optomechanical assembly 12 within the smart glasses 100. This enables the integrated frame assembly 21 to achieve screw-free assembly, high precision, ultra-light weight, low cost, and high mass manufacturability.

[0151] As shown in FIG9 , in some embodiments, the lens mounting member 210 is formed with an optical-mechanical accommodating cavity 212 on one side near the temple assembly 22, and the optical-mechanical assembly 12 is accommodated in the optical-mechanical accommodating cavity 212. This allows the optical-mechanical assembly 12 to be accommodated in the optical-mechanical accommodating cavity 212, preventing the optical-mechanical assembly 12 from being exposed and potentially damaged.

[0152] Specifically, the optical-mechanical housing cavity 212 can be positioned slightly outside the front end of the temple 222, so that the optical-mechanical assembly 12 housed in the optical-mechanical housing cavity 212 is also positioned slightly outside the front end of the temple 222. This design prevents components such as the optical-mechanical assembly 12 from being positioned in front of the wearer's field of view, thereby obstructing the normal field of view of the smart glasses 100, thereby improving the user's wearing comfort.

[0153] In some embodiments, the linear distance between the optical-mechanical assembly 12 and the wearer's head is greater than 20 mm, thereby preventing the optical-mechanical assembly 12 from being too close to the wearer's head, causing discomfort to the wearer.

[0154] The straight-line distance between the optical-mechanical assembly 12 and the wearer's head can be any distance. Generally, if the straight-line distance between the optical-mechanical assembly 12 and the wearer's head is greater than 20 mm, the wearer's discomfort can be effectively reduced.

[0155] Specifically, the optical machine housing cavity 212 can be set at a position with a straight-line distance from the wearer's head greater than 20 mm, and the optical machine component 12 can be placed in the optical machine housing cavity 212, so that the optical machine component 12 is away from the skin around the eyes and more than 20 mm away from the wearer's temple, and will not cause discomfort to the wearer.

[0156] In some embodiments, the main control module is housed in the optical-mechanical housing cavity 212, connected to the optical-mechanical assembly 12, and electrically connected to the battery module 30 via a flexible connector 220. Thus, both the main control module and the optical-mechanical assembly 12 can be housed in the optical-mechanical housing cavity 212, thereby reducing the volume and weight of the frame assembly 21.

[0157] Specifically, the main control module and the optical-mechanical assembly 12 can both be connected to the battery module 30 via the flexible connector 220, thereby enabling the battery module 30 to power the main control module and the optical-mechanical assembly 12, and for the main control module to control the optical-mechanical assembly 12 to emit light. Furthermore, since both the main control module and the optical-mechanical assembly 12 are housed in the optical-mechanical housing cavity 212, the main control module and the optical-mechanical assembly 12 do not need to be connected via the flexible connector 220. Instead, the connection between the main control module and the optical-mechanical assembly 12 can be achieved via wired or wireless means, effectively reducing the size and weight of the frame assembly 21.

[0158] In some embodiments, the main control module and the optical-mechanical assembly 12 are relatively fixed or integrally arranged, thereby effectively reducing the volume and weight of the frame assembly 21.

[0159] To reduce the size and weight of the optomechanical assembly 12 and its peripheral hardware circuitry, the optomechanical assembly 12 in the present embodiment can utilize MicroLED display technology. Compared to DLP, LCOS, and LBS technologies, MicroLED optomechanical displays utilize self-luminous display chips, eliminating the need for an illumination source (DLP, LCOS, LBS, and other technologies utilize reflective luminescence and require an illumination source). This significantly reduces the size and weight of the optomechanical assembly 12. Furthermore, the MicroLED solution incorporates an integrated driver circuit design, making the optomechanical assembly 12's driver circuitry more concise and lightweight.

[0160] This embodiment utilizes a front-to-back stacking design of the optical-mechanical assembly 12 and the main control module. This allows the front end of the overall frame assembly 21 to be slender, significantly reducing line of sight obstruction. The laminated structure, linked by flexible and rigid boards, allows for the most efficient arrangement of various electronic components while ensuring that components interacting with the outside world can be placed at the bottom of the main control module without being affected by the bulk of the optical-mechanical assembly 12.

[0161] Specifically, if the FPC connector and peripheral hardware circuit components are not included, the volume of the optical-mechanical assembly 12 can be less than 0.3 cm 3 This can achieve miniaturization of the optomechanical assembly 12, thereby reducing the volume and weight of the optomechanical assembly 12.

[0162] For example, if the FPC connector and peripheral hardware circuit components are not included, the volume of the optical-mechanical assembly 12 can be 0.1 cm 3 , no specific limitation is given here.

[0163] As shown in Figures 10(a) and 10(b), in some embodiments, the lens mounting member 210 includes a first lens mounting frame 213, a second lens mounting frame 214, and a nose pad 215. The first lens mounting frame 213 is connected to the temple connector 211 and is used to connect to the waveguide assembly 11; the second lens mounting frame 214 is connected to another temple connector 211 and is used to connect to the waveguide assembly 11; and the nose pad 215 is used to connect the first lens mounting frame 213 and the second lens mounting frame 214. Thus, the first lens mounting frame 213 and the second lens mounting frame 214 can be connected via the adjustable nose pad 215, thereby increasing the adjustability of the smart glasses 100, enabling better adaptation to different wearer's face shapes, and improving the wearer's long-term wearing comfort.

[0164] Specifically, the first lens mounting frame 213 is connected to the corresponding temple connector 211, and the waveguide component 11 can be installed in the first lens mounting frame 213, or the first lens mounting frame 213 can also not be installed with the waveguide component 11; the second lens mounting frame 214 is also connected to the corresponding temple connector 211, and the waveguide component 11 can be installed in the second lens mounting frame 214, or the second lens mounting frame 214 can also not be installed with the waveguide component 11, which can be specifically set by the user.

[0165] Specifically, the optical-mechanical images generated by the optical-mechanical component 12 corresponding to the first lens mounting frame 213 and the optical-mechanical component 12 corresponding to the second lens mounting frame 214 can be synchronized through a 2.4G wireless channel, thereby eliminating the physical line connection for signal transmission between the optical-mechanical components 12 and avoiding wiring between the frames, thereby greatly reducing the thickness and weight of the frames, and also avoiding the obstruction of the field of view caused by the optical-mechanical component 12.

[0166] In some embodiments, the nose pad 215 is made of a flexible material. Thus, the first lens mounting frame 213 and the second lens mounting frame 214 can be connected via the adjustable nose pad 215, thereby increasing the adjustability of the smart glasses 100, enabling better adaptation to different wearer's face shapes and enhancing long-term wear comfort.

[0167] The contact surface between the nose pad 215 and the nose bridge can be made of a material that is skin-friendly and has good rebound and cushioning properties, thereby improving the wearing experience of the wearer.

[0168] In some embodiments, the parameters of the nose pads 215 are determined according to the wearer's nose shape. This can increase the adjustment flexibility of the smart glasses 100, better adapt to different wearers' face and nose shapes, and increase the wearer's long-term wearing comfort.

[0169] The parameters of the nose pads 215 include one or more of height, spacing, angle, and shape, which are not specifically limited herein. The height of the nose pads 215 may be the height of the nose pads 215 relative to the nose bridge, the spacing of the nose pads 215 may be the distance between the first lens mounting frame 213 and the second lens mounting frame 214, the angle of the nose pads 215 may be the angle formed by the nose pads 215, and the shape of the nose pads 215 is used to represent the shape of the nose pads 215 after flexible adjustment.

[0170] Exemplarily, the parameters of the nose pad 215 can be determined based on the contact surface between the nose pad 215 and the nose bridge. For example, the size and shape of the nose pad 215 can be determined based on different nose shapes.

[0171] For example, if the user is fitting glasses offline, the facial data of the 3D facial scan can be added, so that the parameters of the nose pads 215 such as the angle and spacing can be pre-adjusted in the offline store. The nose pads 215 can be made of adjustable memory metal material.

[0172] For example, if the nose pad 215 is accidentally lost, the remaining first lens mounting frame 213 and second lens mounting frame 214 in the lens mounting part 210 are also ergonomically designed. After the nose pad 215 is lost or falls off, the smart glasses 100 still meet the wearing requirements and can meet the comfort of short-term wearing.

[0173] In some embodiments, the overall height of the smart glasses 100 can be adjusted by adjusting the nose pads 215 and the position and / or weight of the weight module. This allows the smart glasses 100 to be moved upward relative to the wearer, thereby moving the outcoupling grating region in the waveguide assembly 11 out of the center of the main field of view of the smart glasses 100. This effectively avoids diffraction rainbow fringes in the wearer's main field of view, while also ensuring that AR imaging is implemented in the effective area, allowing the wearer to clearly and accurately see the display information in the outcoupling grating region even when slightly raising their eyes.

[0174] For example, by adjusting the position and / or weight of the weight module, the weight module at the end of the temple 222 can act as a lever relative to the wearer's ear, thereby supporting the front end of the smart glasses 100. This allows the smart glasses 100 to move upward relative to the wearer, thereby moving the outcoupling grating area in the waveguide assembly 11 out of the center of the main field of view of the smart glasses 100, effectively avoiding diffraction rainbow fringes in the wearer's main field of view. At the same time, it can also ensure that the AR imaging function is realized in the effective area, so that the wearer can clearly and accurately see the display information of the outcoupling grating area even if the wearer slightly raises his eyes.

[0175] For example, if only the position and / or weight of the counterweight module is adjusted to move the smart glasses 100 upward as a whole relative to the wearer, the nose pad 215 at the front end of the glasses may be suspended in the air, which is not very convenient for the wearer to wear. Therefore, the parameters of the nose pad 215 can be adjusted accordingly to meet the wearer's wearing needs. On the premise of being able to effectively avoid the diffraction rainbow stripes that appear in the wearer's main field of view, the wearer's wearing experience can also be guaranteed.

[0176] As shown in Figures 11(a) and 11(b), in some embodiments, the smart glasses 100 further include a refractive module 40, which includes a first refractive lens 41 and / or a second refractive lens 42. The first refractive lens 41 is disposed on the first surface of the waveguide assembly 11, and the second refractive lens 42 is disposed on the second surface of the waveguide assembly 11. This can solve the refractive correction problem of the smart glasses 100.

[0177] As shown in FIG11( a ), the refractive module 40 may include only the first refractive lens 41 and not the second refractive lens 42. In this case, the first refractive lens 41 may be disposed on the first surface of the waveguide assembly 11, that is, on the surface of the waveguide assembly 11 closest to the wearer, thereby resolving the refractive correction problem of the smart glasses 100.

[0178] For example, the refractive module 40 may include only the second refractive lens 42, without the first refractive lens 41. In this case, the second refractive lens 42 may be disposed on the second surface of the waveguide assembly 11, that is, on the surface of the waveguide assembly 11 away from the wearer, thereby resolving the refractive correction problem of the smart glasses 100.

[0179] As shown in FIG11( b ), the refractive module 40 may include a first refractive lens 41 and a second refractive lens 42. The first refractive lens 41 may be disposed on the first surface of the waveguide assembly 11, i.e., the surface of the waveguide assembly 11 closer to the wearer, and the second refractive lens 42 may be disposed on the second surface of the waveguide assembly 11, i.e., the surface of the waveguide assembly 11 farther from the wearer, thereby resolving the refractive correction problem of the smart glasses 100.

[0180] In some embodiments, the refractive module 40 and the waveguide assembly 11 are relatively fixed or integrally arranged, thereby making the overall weight of the smart glasses 100 lighter and the overall thickness of the lenses thinner.

[0181] For example, by integrating the refractive module 40 and the waveguide assembly 11, the weight of the refractive module 40 and the waveguide assembly 11 can be made comparable to that of a conventional refractive lens, without adding an extra weight burden on wearing comfort.

[0182] Exemplarily, the waveguide component 11 can also be provided with a transparent lens design with high light transmittance, so that the smart glasses 100 can achieve a visual effect equivalent to that of normal refractive glasses, and the field of vision is not blocked by the additional waveguide component 11.

[0183] The present application provides a pair of smart glasses 100, which include a display module 10, a frame module 20 and a battery module 30; the display module 10 includes an optical-mechanical component 12 and a waveguide component 11, the waveguide component 11 is used to receive display light emitted by the optical-mechanical component 12 and form output light; the frame module 20 includes a frame component 21 and a temple component 22 connected to the frame component 21, the frame component 21 is connected to the waveguide component 11, and the optical-mechanical component 12 and the waveguide component 11 are both installed on the frame component 21; the temple component 22 includes a temple 222 and a flexible connector 220 arranged in the temple 222; the battery module 30 is connected to one end of the temple 222 away from the frame component 21, and the battery module 30 is electrically connected to the optical-mechanical component 12 through the flexible connector 220. Since the temples 222 are flexible, they can be bent into a curved surface and deformed according to the size and shape of the wearer's head, so that the smart glasses 100 can adapt to the head shapes of different wearers and can wrap the wearer's head shape, thereby improving wearing stability and comfort.

[0184] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and such modifications or substitutions should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
