However, in related technologies, antennas are typically attached to the temple shell with double-sided adhesive or soldered to the control module. These antenna configurations lead to poor antenna stability and unsatisfactory antenna communication performance.

[0004] Summary of the Invention

[0005] This application provides a smart glasses solution that addresses the problems of poor antenna stability and unsatisfactory antenna communication performance in related technologies.

[0006] In a first aspect, this application provides a smart glasses, which includes a display module, a frame module, a control module, and an antenna module;

The optomechanical assembly and the waveguide assembly are both mounted on the frame assembly. The temple assembly includes a temple, a flexible connector disposed within the temple, and a receiving cavity connected to the temple. The flexible connector is electrically connected to the temple. The housing of the receiving cavity includes a first housing portion connected to the temple and a second housing portion not connected to the temple.

[0009] The control module is disposed within the accommodating cavity, and the control module is electrically connected to the flexible connector;

[0011] This application provides smart glasses, which include a display module, a frame module, a control module, and an antenna module. The display module includes an optomechanical assembly and a waveguide assembly. The waveguide assembly receives display light emitted by the optomechanical assembly and forms outgoing light. 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. Both the optomechanical assembly and the waveguide assembly are mounted on the frame assembly.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0019] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the 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.

[0020] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Currently, when users perform different functions using smart glasses, antennas are often needed to enable interaction between the smart glasses and external electronic devices, or to facilitate interaction between the display modules on both sides of the smart glasses. However, in related technologies, antennas are typically attached to the temple shell with double-sided adhesive or soldered to the control module. These antenna configurations lead to poor antenna stability and unsatisfactory antenna communication performance.

[0023] Existing smart glasses typically use FPC antennas or ceramic antennas to interact with external electronic devices. For communication via FPC or ceramic antennas, the FPC antenna, attached to the temple shell with double-sided adhesive, is prone to loosening, potentially leading to unstable communication. Ceramic antennas, on the other hand, need to be soldered onto the control module, requiring a larger unused area within the module. Since control modules are generally small and structurally limited, this also results in less than ideal wireless communication performance for ceramic antennas.

[0024] To address the shortcomings of the existing technology, this application proposes a smart glasses. This smart glasses can achieve this by coupling a second antenna to the temples. The coupling and grounding portions can be equivalent to a matching circuit, allowing the temple assembly, control module, and antenna module to form a loop. This lengthens the antenna circuit, effectively increasing the antenna's radiation area and height, and also avoids interference from other components, thereby enhancing the antenna module's anti-interference capability and signal stability.

[0025] For example, the smart glasses can be AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, or any other electronic device that can be used for AR imaging, such as a smart helmet or other smart wearable device, without any specific limitations.

[0026] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the structure of a smart glasses provided in an embodiment of this application; Figure 2 is a schematic diagram of the structure of another smart glasses provided in an embodiment of this application.

[0027] As shown in Figures 1 and 2, the smart glasses 100 includes a display module 10, a frame module 20, a control module 30, and an antenna module 40. The display module 10 may include an optomechanical component 12 and a waveguide component 11. The waveguide component 11 is used to receive the display light emitted by the optomechanical component 12 and form the outgoing light. Specifically, the waveguide component 11 is provided with a waveguide substrate, a coupling grating region, and a coupling grating region. The optomechanical component 12 is connected to the frame component 21 and is provided corresponding to the coupling grating region. The coupling grating region and the coupling grating region can be located on the waveguide substrate. The coupling grating region is used to couple light into the waveguide substrate, and the coupling grating region is used to couple light propagating within the waveguide substrate out. The light emitted by the optomechanical component 12 enters the coupling grating region, and the light diffracted by the coupling grating region can undergo total internal reflection within the waveguide substrate, thus propagating laterally within the waveguide component 11 until it reaches the coupling grating region, where it is diffracted again before reaching the human eye for imaging.

[0028] For example, the coupling-in grating region and the coupling-out grating region can also be disposed on different surfaces of the waveguide substrate. For instance, the coupling-in grating region can be disposed on a first surface of the waveguide substrate, and the coupling-out grating region on a second surface of the waveguide substrate; or, the coupling-out grating region can be disposed on a first surface of the waveguide substrate, and the coupling-in grating region on a second surface of the waveguide substrate. This is as long as the coupling-in grating region can couple light into the waveguide substrate, and the coupling-out grating region can couple light propagating within the waveguide substrate out.

[0029] 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. The optomechanical assembly 12 and the waveguide assembly 11 are both mounted on the frame assembly 21. The temple assembly 22 includes a temple 220, a flexible connector 221 disposed in the temple 220, and a receiving cavity 23 connected to the temple 220. The flexible connector 221 is electrically connected to the temple 220. The housing of the receiving cavity 23 includes a first housing portion 231 connected to the temple 220 and a second housing portion 232 not connected to the temple 220.

[0030] The flexible connector 221 can 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 221 can be electrically connected to the temple 220, so that both the temple 220 and the flexible connector 221 can become conductive paths.

[0031] For example, the portion of the housing of the accommodating cavity 23 that is connected to the temple 220 is the first housing portion 231, and the portion of the housing of the accommodating cavity 23 that is not connected to the temple 220 is the second housing portion 232.

[0032] It should be noted that the receiving cavity 23 can be a cavity opened inside the temple 220 or an external cavity. The receiving cavity 23 can be integrally set with the temple 220 or detachably connected to the temple 220. No specific limitation is made here.

[0033] The control module 30 is disposed within the accommodating cavity 23 and is electrically connected to the flexible connector 221. The antenna module 40 includes a first antenna 41 and a second antenna 42. Both the first antenna 41 and the second antenna 42 are electrically connected to the control module 30. The first antenna 41 is disposed in the second housing portion 232, and the second antenna 42 is at least partially disposed in the first housing portion 231 and coupled to the temple 220, so that the temple assembly 22, the control module 30 and the antenna module 40 form a loop.

[0034] The control module 30 can be a PCBA board, which refers to a product on a PCB board where integrated circuits and other electronic components are soldered and mounted to achieve circuit functions. The first antenna 41 is used to transmit radio frequency signals, and the second antenna 42 is used as a ground wire. The coupling connection can include radial connection, electrical connection, etc. The flexible connector 221 and the control module 30 can be electrically connected through conductive cloth, conductive foam, SMT springs, solder wires, etc.; the first antenna 41, the second antenna 42 and the control module 30 can also be electrically connected through conductive cloth, conductive foam, SMT springs, solder wires, etc., without specific limitations.

[0035] Specifically, since the second antenna 42 is at least partially disposed in the first housing portion 231, the second antenna 42 located in the first housing portion 231 is correspondingly disposed with the temple 220, thereby realizing the coupling connection between the second antenna 42 and the temple 220. At this time, the coupling portion and the grounding portion can be equivalent to a matching circuit. Since the temple 220 is electrically connected to the flexible connector 221, and the flexible connector 221, the first antenna 41, and the second antenna 42 are all electrically connected to the control module 30, the second antenna 42, the temple 220, the flexible connector 221, and the control module 30 form a conductive path, and the temple assembly 22, the control module 30, and the antenna module 40 form a loop, thereby achieving the effect of extending the antenna ground wire and making the circuit corresponding to the antenna longer, effectively increasing the antenna radiation area and antenna height, and also avoiding interference from other components to the antenna signal, thereby enhancing the anti-interference capability and signal stability of the antenna module 40.

[0036] The coupling section and the grounding section can be equivalent to a matching circuit, which can also adjust various parameters of the antenna, thus giving the coupled loop antenna high flexibility. For example, the antenna parameters can be adjusted by changing the length, volume, and other parameters of the coupling section, thereby flexibly adjusting the coupled loop antenna.

[0037] In some embodiments, the second antenna 42 is spaced apart from the temple 220, and a signal is radiated to the temple 220 to achieve a coupling connection between the second antenna 42 and the temple assembly 22. This radiative connection enables the coupling connection between the second antenna 42 and the temple assembly 22, thereby forming a conductive path between the second antenna 42 and the temple 220.

[0038] Specifically, the temple assembly 22 also includes a flexible member 222, which is used to seal the flexible connector 221, and is located on the side of the temple assembly 22 facing the wearer. The accommodating cavity 23 is connected to the flexible member 222, which can be a pre-formed silicone strip or rubber strip made of a flexible, skin-friendly material. Since the second antenna 42 is at least partially located in the first housing portion 231, the second antenna 42 located in the first housing portion 231 is correspondingly positioned with the temple 220. In this case, the second antenna 42 can radiate signals to the temple 220 to achieve coupling connection between the second antenna 42 and the temple assembly 22, thus allowing the temple 220 to become part of the antenna module 40. This effectively increases the area and antenna height of the antenna module 40 and avoids interference from other components on the antenna signal.

[0039] The above-mentioned design of extending the temple 220 and antenna coupling also increases the distance between the antenna and the head, thus cleverly avoiding signal attenuation caused by the head and providing a good signal enhancement effect for wireless communication between the temples 220, minimizing the absorption of antenna signals by the head.

[0040] As shown in Figure 3, in some embodiments, the feed terminal of the first antenna 41 is electrically connected to the feed terminal of the control module 30, and the ground terminal of the first antenna 41 is electrically connected to the ground terminal of the control module 30. Thus, the first antenna 41 and the control module 30 can be electrically connected through the feed terminal and the ground terminal.

[0041] The first antenna 41 can be electrically connected to the control module 30 through FPC, conductive cloth, conductive foam, SMT spring, solder wire, etc., to achieve the connection between the feed point and the ground point. No specific limitation is made here.

[0042] For example, the feed point of the first antenna 41 and the feed terminal of the control module 30 can be connected by an SMT spring; the ground terminal of the first antenna 41 and the ground terminal on the circuit board can also be connected by an SMT spring.

[0043] In some embodiments, the feed terminal of the second antenna 42 is electrically connected to the ground terminal of the control module 30. This allows for the electrical connection between the second antenna 42 and the control module 30 via the feed terminal and the ground terminal.

[0044] For example, the power supply terminal of the second antenna 42 can be connected to another ground terminal of the control module 30 via an SMT spring connection.

[0045] In related technologies, the housing of the accommodating cavity 23 generally only includes the first antenna 41 and does not include the second antenna 42. In this case, the first antenna 41 forms a shorter loop, and the antenna radiation area and antenna height are smaller, resulting in weaker anti-interference capability and signal stability of the antenna module 40.

[0046] In this embodiment, since the feed terminal of the second antenna 42 is electrically connected to another ground terminal of the control module 30, that is, the feed terminal of the second antenna 42 is connected to the ground terminal of the first antenna 41, and the second antenna 42 is coupled to the temple 220, the temple 220 is connected to the flexible connector 221, and the flexible connector 221 is connected to the ground terminal of the control module 30, the temple 220 and the flexible connector 221 are made part of the ground wire, thereby effectively increasing the area and antenna height of the antenna module 40, and avoiding interference from other components to the antenna signal. Through the above-mentioned temple 220 and antenna coupling extension design, the distance between the antenna and the head can also be increased, thereby cleverly avoiding the attenuation of the signal by the head, which has a good signal strengthening effect on the wireless communication between the temples 220, and minimizes the absorption of the antenna signal by the head.

[0047] In some embodiments, the first antenna 41 is a PIFA antenna and the second antenna 42 is a parasitic antenna.

[0048] The PIFA antenna is a planar inverted F-shaped antenna, which uses planar radiating elements as radiators and a large ground plane as a reflector. It boasts advantages such as compact structure, stable performance, and ease of integration. Parasitic antennas are used to improve or extend the performance of existing antennas, particularly in terms of frequency coverage and bandwidth.

[0049] Specifically, the PIFA antenna can be placed at any position in the second housing 232. Generally, it is necessary to increase the antenna radiation area of ​​the PIFA antenna as much as possible, so as to improve the communication quality of the antenna.

[0050] In some embodiments, the first antenna 41 and the second antenna 42 are fabricated using laser forming, printing forming, or flexible printed circuit technology.

[0051] For example, the first antenna 41 and the second antenna 42 can be fabricated using a laser direct forming (LDS) process. Specifically, a computer can be used to control the movement of the laser according to the trajectory of the conductive pattern, and the laser can be projected onto the housing of the molded cavity 23 to activate the circuit pattern and then form a metal antenna.

[0052] For example, the first antenna 41 and the second antenna 42 can be fabricated using a printed direct molding (PDS) process. Specifically, the pattern can be printed on the housing of the accommodating cavity 23 by exposing, developing and etching a photosensitive adhesive and film on a steel plate, using a pad printing machine, and then the final antenna can be fabricated by thermosetting.

[0053] Antennas fabricated using the FPC process require double-sided adhesive for fixation, which carries a risk of detachment and results in poor stability. In contrast, antennas fabricated using the LDS process are laser-engraved and electroplated onto the housing, preventing detachment. Therefore, antennas fabricated using the LDS process are more reliable than those fabricated using the traditional FPC process. Since the LDS antenna is directly laser-engraved onto the housing and utilizes the temple 220 as the antenna itself, the structure does not require consideration of antenna position or fixation method, making it very convenient for design. Furthermore, no additional antenna assembly is needed during production, making it more suitable for mass production.

[0054] Of course, the first antenna 41 and the second antenna 42 can also be fabricated using flexible printed circuit (FPC) technology in the embodiments of this application. Specifically, a patterned printed circuit board made of flexible substrate can be used, which consists of an insulating substrate and a conductive layer and can be attached to the housing of the accommodating cavity 23.

[0055] In some embodiments, the housing of the accommodating cavity 23 is made of insulating plastic. This facilitates the formation of a metal antenna on the plastic housing.

[0056] For example, both LDS and PDS processes form metal antennas on plastic shells. The main difference between the two is the manufacturing process. LDS uses laser engraving and plating, while PDS uses silver paste printing.

[0057] In some embodiments, the material of the temple 220 may include a conductive metal. This allows the temple 220 itself to be conductive, thereby enabling the temple 220 to be coupled to the second antenna 42 and electrically connected to the flexible connector 221.

[0058] The conductive metal can include silver, copper, gold, etc., as long as it is a metallic material that can conduct electricity.

[0059] In some embodiments, the flexible connector 221 may include a flexible printed circuit board. This allows for an electrical connection between the temple 220 and the control module 30 via a highly reliable and highly flexible printed circuit board.

[0060] Flexible printed circuit boards (FPCBs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending properties.

[0061] Because flexible printed circuit boards have the characteristics of high wiring density, light weight, thinness and good bending, they can be used as an electrical connection medium between battery module 50 and control module 30. At the same time, the flexible printed circuit board is also placed inside the temple 220. As long as the temple 220 is also a conductive material, the electrical connection between battery module 50 and control module 30 can be achieved.

[0062] In some embodiments, the accommodating cavity 23 further includes a reflector 60 disposed on the housing. The reflector 60 is disposed on the side of the housing near the wearer's head and is electrically connected to the control module 30. The reflector 60 is used to reflect the radio frequency signal emitted by the first antenna 41.

[0063] The reflector 60 can be provided on the entire surface of the shell on the side closest to the wearer's head, or it can be provided on a portion of the surface of the shell on the side closest to the wearer's head.

[0064] Specifically, the reflector 60 can be electrically connected to the ground terminal of the control module 30. The reflector 60 is used to reflect the radio frequency signal emitted by the first antenna 41, thereby reflecting the radio frequency signal emitted by the first antenna 41 as much as possible, thus avoiding the radio frequency signal attenuation caused by the person's head, and thus improving the quality of the communication signal.

[0065] For example, the reflector 60 can be electrically connected to the control module 30 through FPC, conductive cloth, conductive foam, SMT spring, solder wire, etc., without specific limitations.

[0066] For example, the reflector 60 can be prepared by laser forming, printing forming or flexible printed circuit process.

[0067] For example, a reflector 60 can be provided on the inner wall of the housing or on the outer wall of the housing, as long as it is provided on the side of the housing close to the wearer's head.

[0068] It should be noted that the first antenna 41 and the reflector 60 are generally not placed on the side of the housing closest to the wearer's head at the same time, so as to avoid the reflector 60 being unable to reflect the radio frequency signal emitted by the first antenna 41.

[0069] As shown in Figure 4, in some embodiments, the reflector 60 is disposed in the housing on the side close to the wearer's head, and the reflector 60 is disposed on both the inner and outer walls of the housing. This can improve the signal reflection effect, thereby further avoiding signal attenuation caused by the wearer's head.

[0070] For example, a reflector 60 can be added to the inner surface of the plastic housing, or a reflector 60 can be added to the outer surface of the plastic housing. This can reflect the radio frequency signal emitted by the first antenna 41 as much as possible and improve the attenuation prevention effect.

[0071] It should be noted that the two reflectors 60 can be conductive or non-conductive, both achieving the effect of signal reflection. The design of dual reflectors 60 fully utilizes the characteristic of LDS (or PDS) technology that allows circuitry to be deployed on both the inner and outer layers of the housing, resulting in better signal reflection and further preventing signal attenuation caused by human heads.

[0072] In some embodiments, the end of the temple 220 away from the frame assembly 21 forms an ear loop 225, and a receiving cavity 23 is located in the ear loop 225. This allows the receiving cavity 23 to be hidden behind the ear and also balances the weight of the temple 220 in the front and back, thereby improving wearing stability and wearing comfort.

[0073] Specifically, the temple 220 may include an ear loop 225, a temple body 224, and a frame connecting part 223. The frame connecting part 223 is used to connect with the frame assembly 21, and the temple body 224 is used to connect the frame connecting part 223 and the ear loop 225. The receiving cavity 23 may be located in the temple body 224 or in the ear loop 225. Generally, the receiving cavity 23 is located in the ear loop 225 of the temple 220, and the receiving cavity 23 is located on the side of the ear loop 225 closer to the wearer. This arrangement can hide the receiving cavity 23 behind the ear and can also conform to the shape of the wearer's ear to fix the glasses in place, thereby increasing the wearing stability of the smart glasses 100.

[0074] In some embodiments, the accommodating cavity 23 further includes a battery module 50, which is electrically connected to the flexible connector 221 and the control module 30. This not only enables the battery module 50 to quickly power the main control module, but also further reduces the size and weight of the frame assembly 21, allowing the temples 220 to achieve balance at both ends, 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 bridge of the nose, and improving the user's wearing comfort.

[0075] Specifically, the battery module 50 is connected to the flexible connector 221, thereby electrically connecting to the optomechanical assembly 12 through the flexible connector 221, thus providing power to the optomechanical assembly 12 and other components. This allows the temples 220 to achieve balance at both ends, 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 bridge of the nose, and improving the user's wearing comfort.

[0076] This application provides a smart glasses 100, which includes a display module 10, a frame module 20, a control module 30, and an antenna module 40. The display module 10 includes 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 outgoing light. 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. The optomechanical assembly 12 and the waveguide assembly 11 are both mounted on the frame assembly 21. The temple assembly 22 includes a temple 220, a flexible connector 221 disposed in the temple 220, and a receiving cavity 23 connected to the temple 220. The connector 221 is electrically connected to the temple 220. The housing of the accommodating cavity 23 includes a first housing portion 231 connected to the temple 220 and a second housing portion 232 not connected to the temple 220. The control module 30 is disposed in the accommodating cavity 23 and is electrically connected to the flexible connector 221. The antenna module 40 includes a first antenna 41 and a second antenna 42. Both the first antenna 41 and the second antenna 42 are electrically connected to the control module 30. The first antenna 41 is disposed in the second housing portion 232, and the second antenna 42 is at least partially disposed in the first housing portion 231 and coupled to the temple 220, so that the temple assembly 22, the control module 30 and the antenna module 40 form a loop. Thus, by coupling the second antenna 42 to the temple 220, the coupling part and the grounding part can be equivalent to a matching circuit, so that the temple assembly 22, the control module 30 and the antenna module 40 form a loop, thereby making the circuit corresponding to the antenna longer, effectively increasing the antenna radiation area and antenna height, and avoiding interference from other components to the antenna signal, thereby enhancing the anti-interference capability and signal stability of the antenna module 40.

[0077] The above are merely specific embodiments of this application, but the scope of protection of this 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 these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
