Smart glasses

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 29, 2024, with application number 202420397145.9 and invention name “Smart Glasses”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of smart glasses, and in particular to smart glasses. Background Art

[0003] Currently, to conceal some electronic components, smart glasses typically require cavities within the temples to house these components. To protect these components, the cavities are typically constructed of hard materials. This increased thickness and width of the temples complicates both the volume and weight of the temples, impacting the aesthetics and wearing experience of the smart glasses. Furthermore, most smart glasses have rigid, non-bendable plastic temples, making them difficult to adapt to the wearer's head shape, resulting in poor wearing stability and comfort.

[0004] Summary of the Invention

[0005] The present application provides a pair of smart glasses that can solve the problem of poor wearing stability and comfort of smart glasses due to the fact that the temples of the smart glasses are too large and cannot be bent.

[0006] In a first aspect, the present application provides a pair of smart glasses, comprising a display module, a frame module, and a battery module;

[0007] The display module includes an optical-mechanical component and a waveguide component, wherein the waveguide component is used to receive the display light emitted by the optical-mechanical component and form an output light;

[0008] The frame module includes a frame assembly and a temple assembly connected to the frame assembly, the frame assembly is connected to the waveguide assembly, and the optical mechanical assembly and the waveguide assembly are both mounted on the frame assembly; the temple assembly includes temples and flexible connectors disposed within the temples, the temples include a frame connecting portion, a temple body, and an ear hanging portion, the frame connecting portion is used to connect to the frame assembly, and the temple body is used to connect the frame connecting portion and the ear hanging portion;

[0009] The battery module is arranged on the ear hanging portion, and the battery module is electrically connected to the optical-mechanical assembly via the flexible connector;

[0010] The temple body is flexible, and the thickness of the temple body is less than or equal to 5 mm, and the width of the temple body is less than or equal to 10 mm, so that the temple can be deformed according to the head size and shape of the wearer.

[0011] The present application provides smart glasses, which include a display module, a frame module, and a battery module. The display module includes an optomechanical assembly and a waveguide assembly, the waveguide assembly being configured to receive display light emitted by the optomechanical assembly and form output light. The frame module includes a frame assembly and a temple assembly connected to the frame assembly, the frame assembly being connected to the waveguide assembly, and both the optomechanical assembly and the waveguide assembly being mounted on the frame assembly. The temple assembly includes a temple and a flexible connector disposed within the temple. The temple includes a frame connecting portion, a temple body, and an ear hook portion. The frame connecting portion is configured to connect to the frame assembly. The temple body is configured to connect the frame connecting portion to the ear hook portion. The battery module is disposed in the ear hook portion and is electrically connected to the optomechanical assembly via the flexible connector. The temple body is flexible, has a thickness of less than or equal to 5 mm, and a width of less than or equal to 10 mm, so that the temple can deform according to the size and shape of the wearer's head. Because the temple body is flexible, the temple can be bent into a curved surface and can be deformed according to the wearer's head size and shape, so that the smart glasses can adapt to the head shapes of different wearers and can form a wrapping effect on the wearer's head shape. At the same time, the thickness and width of the temple body are reduced, thereby reducing the volume and weight of the smart glasses, making the smart glasses lighter and more beautiful, and improving wearing stability and comfort.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] To address the above-mentioned deficiencies in the 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 them. The thickness and width of the temples are also reduced, thereby reducing the volume and weight of the smart glasses, thereby improving wearing stability and comfort.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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 222 and a flexible connector 220 disposed within the temple 222. The temple 222 includes an ear hook 226, a temple body 227, and a frame connection 228. The frame connection 228 is used to connect to the frame assembly 21, and the temple body 227 is used to connect the frame connection 228 to the ear hook 226. The battery module 30 is disposed in the ear hook 226 and is electrically connected to the optical-mechanical assembly 12 via the flexible connector.

[0036] 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.

[0037] Specifically, the battery module 30 can be set in the ear-hanging portion 226 of the temple 222, and the battery module 30 does not need to be set inside the temple 222, but is installed on the ear-hanging 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 be deformed according to the wearer's head size and head 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 to provide power to the optical-mechanical assembly 12 and other components. In this way, the ear-hanging design with the battery module 30 placed behind the smart glasses 100 can further increase the wearing stability of the smart glasses 100, and the glasses can be fixed in place by matching the wearer's ear shape, thereby increasing the wearing stability of the smart glasses 100.

[0038] 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 wearing stability of the smart glasses 100. At the same time, the downward pressure applied behind the ear can increase the friction between the silicone on the temple 222 and the contact surface of the ear. 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.

[0039] 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.

[0040] As shown in FIG4 , specifically, the temple body 227 is flexible, and the thickness d of the temple body 227 is less than or equal to 5 mm, and the width w of the temple body 227 is less than or equal to 10 mm, so that the temple can be deformed according to the size and shape of the wearer's head. Since the smart glasses provided by the present application do not need to install electronic components such as electronic components inside the temple body 227, it is only necessary to set a flexible connector 220 inside the temple body 227 to achieve electrical connection between the battery module 30 and the optical-mechanical assembly 12. The flexible connector 220 is generally a flexible printed circuit board with high wiring density, light weight, thin thickness, and good bendability. Therefore, it can effectively reduce the thickness d and width w of the temple body 227, thereby reducing the volume and weight of the smart glasses, thereby improving wearing stability and comfort.

[0041] 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.

[0042] In some embodiments, the thickness d of the temple body 227 is less than or equal to 2 mm, and the width w of the temple body 227 is less than or equal to 5 mm. Therefore, the thickness d and width w of the temple body 227 can be further reduced according to actual conditions, thereby reducing the volume and weight of the smart glasses 100, thereby improving wearing stability and comfort.

[0043] Specifically, the thickness d of the temple body can be 2 mm, and the width w of the temple body can be less than or equal to 5 mm. This makes the thickness d and width w of the temple body 227 smaller, thereby achieving a smaller size, thereby reducing the volume and weight of the smart glasses 100, making the smart glasses 100 more lightweight and beautiful, and further improving wearing stability and comfort.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] As shown in FIG5 , 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] Specifically, the temples 222 and 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 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 between the temples 222 and the face.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] As shown in FIG6 , 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 avoids the problem of yellowing of the flexible member 223 due to prolonged wear of the smart glasses 100.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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 yellowing of the flexible member 223 due to prolonged wear of the smart glasses 100, and allows users to remove and customize the flexible member 223.

[0062] The protrusions may be plastic protrusions, which may be formed by injection molding or the like.

[0063] As shown in FIG6 , 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] As shown in FIG7 , 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] The included angle corresponding to the preset arc can be any angle, such as 150°, and is not specifically limited here.

[0078] As shown in FIG8 , 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.

[0079] 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.

[0080] As shown in FIG9(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 to 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.

[0081] As shown in FIG9( 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 more wearers' head shapes and ear positions.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Specifically, the main control module can also be installed at the end of the temple 222 away from the frame assembly 21 by means of dispensing glue, 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] As shown in FIG10 , 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.

[0092] 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 .

[0093] 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.

[0094] 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.

[0095] As shown in FIG10 , in some embodiments, the lens mount 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] To reduce the size and weight of the optomechanical assembly 12 and its peripheral hardware circuits, the optomechanical assembly 12 of the present embodiment can utilize MicroLED optomechanical display technology. Compared to DLP, LCOS, and LBS technologies, MicroLED optomechanical displays utilize self-luminous light source chips, eliminating the need for an illumination source (DLP, LCOS, LBS, and other technologies are reflective and require an illumination source). This significantly reduces the size and weight of the optomechanical assembly 12. Furthermore, the drive circuitry of the MicroLED solution is also integrated, making the optomechanical assembly 12's drive circuitry more concise and lightweight.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.
