Description

Technical Field

[0001] This application belongs to the field of smart glasses technology, and more specifically, relates to a miniaturized, multifunctional, and comfortable-to-wear temple and smart glasses. Background Technology

[0002] As a core category of wearable smart devices, smart glasses have become an important development direction in the consumer electronics and smart wearable fields in recent years.

[0003] As market demands for the full functionality of smart glasses increase, the number of integrated hardware components will inevitably rise, with these components concentrated in the temples. The temples, constrained by both wearing comfort and product design, must maintain a compact structure. This creates a conflict between the multi-functional expansion of smart glasses and their small size, making it difficult to accommodate multiple types of hardware components within a limited space.

[0004] In existing technical solutions, the temples of smart glasses are generally too large and too long, which not only affects the ease of wearing them, but also reduces the user's wearing comfort.

[0005] Therefore, there is an urgent need for a type of temple that can efficiently integrate various functional components within a limited space, taking into account product functionality, performance, and user experience. Summary of the Invention

[0006] The purpose of this application is to provide a temple and smart glasses to solve the technical problems of existing smart glasses temples, such as large size, limited functions, low integration, and uncomfortable wearing.

[0007] To achieve the above objectives, the technical solution adopted in this application is: to provide a temple, including a temple body, a circuit board, and a battery. The temple body has an internal cavity, and one end of the temple body is a frame connecting part that is adapted to and connected to the frame. A circuit board is installed in the receiving cavity. The circuit board includes a rigid circuit board (PCB), a front flexible circuit board (FPC), and a rear flexible circuit board (FPC). The rigid circuit board (PCB) is located in the middle section of the receiving cavity. One end of the rigid circuit board (PCB) is electrically and structurally connected to the front flexible circuit board (FPC), and the other end of the rigid circuit board (PCB) is electrically and structurally connected to the rear flexible circuit board (FPC). The front flexible circuit board (FPC) is positioned at the end of the receiving cavity near the frame connection, and the rear flexible circuit board (FPC) is positioned at the end of the receiving cavity away from the frame connection. The back of the circuit board faces and is positioned close to the side of the temple body that fits against the human body during use. A core chipset is provided on the rigid circuit board (PCB) for wireless interaction, data storage, and spatial awareness. A functional module is provided on the front flexible circuit board (FPC) for audio interaction functionality of the smart glasses. A battery is fixedly installed inside the temple body at the end away from the frame connection and is electrically connected to the rear flexible circuit board (FPC).

[0008] Optionally, the end of the temple body away from the frame connection is a charging part, and a charging cable is provided in the charging part. The charging cable is electrically connected to the battery and the circuit board respectively. A diode is integrated on the circuit board, and the charging cable is electrically connected to the diode. The diode is used to realize the forward and reverse connection protection of the charging circuit.

[0009] Optionally, the rigid circuit board (PCB) has antenna springs and wearing sensor springs respectively on its front and back sides. A wearing sensor FPC is provided on the inner surface of the side of the temple body that is in contact with the human body during use. The area of ​​the outer surface of the temple body that is in contact with the human body during use and near the ear is the wearing sensor area. The wearing sensor springs and the wearing sensor FPC are positioned correspondingly and elastically engage. An antenna FPC is provided on the inner surface of the side of the temple body that is away from the human body during use. The antenna springs and the antenna FPC are positioned correspondingly and elastically engage. Both the wearing sensor FPC and the antenna FPC are electrically connected to the rigid circuit board (PCB).

[0010] Optionally, the functional module includes a front microphone, a rear microphone, and a speaker. The front microphone and the rear microphone are respectively disposed on both ends of the front flexible circuit board (FPC), and the speaker is disposed between the front microphone and the rear microphone.

[0011] Optionally, the front flexible circuit board (FPC) has a touch pin fixed on the side facing away from the human body during use, and the temple body has a temple touch switch on the outer surface away from the human body during use. The temple touch switch and the touch pin are positioned correspondingly. The temple touch switch is located near the area in front of the speaker so that the preset function can be realized by the vibration generated by the user's touch action.

[0012] Optionally, the core chipset includes a Bluetooth main control chip, a storage chip, and a gyroscope chip.

[0013] Optionally, the core chipset is disposed on the rigid circuit board PCB, and the core chipset includes a Bluetooth main control chip, a storage chip, and a gyroscope chip.

[0014] Optionally, the rigid circuit board (PCB) is provided with a power management unit and indicator lights.

[0015] Optionally, the temple body includes a shell and a cover. The shell has a concave cross-section and an internal cavity. The cover is detachably assembled to one side of the shell. The shell and the cover together form the receiving cavity and constitute the temple body.

[0017] This utility model embodiment also provides a smart glasses, including the aforementioned temples.

[0018] The beneficial effects of the temple and smart glasses provided in this application are as follows: compared with the traditional smart glasses temple design that only uses a rigid circuit board (PCB), this application adopts a rigid-flex board structure, which achieves a balance between mechanical strength and spatial adaptability.

[0019] Specifically, existing technologies using rigid PCBs require sufficient clearance inside the temples to accommodate their structure, due to the fixed shape and inflexibility of the PCB. This is especially true where bending is required on one side of the temple, where the rigidity of the PCB increases space occupancy and ultimately enlarges the temple size. In contrast, the rigid-flex PCB design of this application, in addition to providing a stable mounting base for the components, utilizes flexible PCBs specifically designed for bending areas of the temples. This fully leverages the flexible PCB's adaptability and flexibility, eliminating the need for additional rigid clearance space. The flexible PCB's deformation directly adapts to the bending requirements of the temples, significantly reducing the internal space occupancy of the temples.

[0020] In summary, the technical solution of this application effectively solves the pain points of existing smart glasses temples, such as excessive size and excessive length. Without reducing the functionality, it achieves a miniaturized upgrade of the temple structure, reducing the overall size by half compared to similar products. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] The present application will now describe a temple and smart glasses provided in the embodiments of this application.

[0029] See Figures 1 to 3The present application provides a temple for eyeglasses, including a temple body 3, a circuit board 5, and a battery 4. The temple body 3 has an internal cavity 32 that provides mounting space for various electronic components. One end of the temple body 3 is a frame connector 31 that is adapted to and connected to the eyeglass frame.

[0030] Circuit board 5 is installed in the receiving cavity 32, and circuit board 5 includes a rigid circuit board PCB 51, a front flexible circuit board FPC 52, and a rear flexible circuit board FPC 53. That is, the rigid circuit board PCB 51 is combined with the front flexible circuit board FPC 52 and the rear flexible circuit board FPC 53 to form a rigid-flex board structure. Specifically, the rigid circuit board PCB 51 is arranged in the middle section of the receiving cavity 32. The rigid circuit board PCB 51 serves as the core carrier substrate, providing a stable mounting platform and electrical connection foundation for electronic components, ensuring that it is not easily displaced under force or vibration.

[0031] One end of the rigid circuit board PCB 51 is electrically and structurally connected to the front flexible circuit board FPC 52, and the other end of the rigid circuit board PCB 51 is electrically and structurally connected to the rear flexible circuit board FPC 53. The front flexible circuit board FPC 52 is located at the end of the receiving cavity 32 near the frame connection part 31, while the rear flexible circuit board FPC 53 is located at the end of the receiving cavity 32 away from the frame connection part 31. With their good flexibility, the front flexible circuit board FPC 52 and the rear flexible circuit board FPC 53 can flexibly route the wiring according to the internal space of the temple, bypassing structural interference in a limited space, which is conducive to the compactness of the overall structure.

[0032] To achieve high integration and control the thickness of the circuit board 5 within a limited space, components can be mounted on both sides of the circuit board 5. The back of the circuit board 5 faces and is positioned closer to the side of the temple body 3 that fits against the body during use. Some components related to core operating functions are located on the front of the circuit board 5, while some sensing components are located on the back. A core chipset 513 is mounted on the rigid circuit board PCB 51, which enables wireless interaction, data storage, and spatial awareness. Wireless interaction refers to the smart glasses' ability to connect to mobile phones, tablets, and other terminal devices to transmit audio streams, receive control commands, and transmit device status. Data storage refers to the ability to store device data, supporting fast read / write and long-term storage. Spatial awareness allows for real-time acquisition of the wearer's head posture data, providing data support for AR interaction, head gesture control, and other functions. A functional module 6 is also mounted on the front flexible circuit board FPC 52, which enables the smart glasses' audio interaction function.

[0033] The battery 4 is fixedly installed inside the temple body 3 at one end away from the frame connector 31 and electrically connected to the rear flexible circuit board FPC 53. Since the frame connector 31 needs to be assembled with the frame, sufficient connection space needs to be reserved in the area near the frame connector 31. Placing the battery 4 away from the frame connector 31 and electrically connecting it to the rear flexible circuit board FPC 53 not only facilitates the charging and discharging of the battery 4, but also makes the center of gravity distribution of the temple more even, reducing the feeling of the temple sagging due to the shift in the center of gravity when wearing it, thereby improving wearing stability.

[0034] This application addresses the common pain points of existing smart glasses temples, such as excessive size and length. By rationally allocating the installation space of the circuit board 5 and battery 4, it achieves a compact arrangement of components, effectively controls the overall size of the temples, and reserves a stable working space for each functional component, ensuring the normal functioning of the device.

[0035] The cavity 32 inside the main body 3 of the temple provides protection for the aforementioned electronic components. As a dedicated installation space, it not only provides a basis for the compact arrangement of various components, but also provides reliable protection for core components such as internal circuits and battery 4, isolating them from interference and damage from the external environment, and further enhancing the stability of the temple structure.

[0036] The circuit board 5 is designed as a rigid-flex board consisting of a rigid PCB 51, a front flexible PCB 52, and a rear flexible PCB 53. This rigid-flex board structure achieves a balance between mechanical strength and spatial adaptability. The rigid PCB 51, as the core support, provides reliable installation stability and connection reliability for components such as the core chipset 513 mounted on it, preventing circuit performance from being affected by vibrations or structural deformation. The front and rear flexible PCBs, FPC 52 and FPC 53, can flexibly adapt to irregular spaces within the temples, achieving efficient space utilization. They also extend to the front of the temples, facilitating the connection of various interactive components and expanding the flexibility of the functional layout. Furthermore, during wear or when the temples are subjected to external impact, the front and rear flexible PCBs, FPC 52 and FPC 53, can absorb stress through their own deformation, effectively buffering mechanical damage to the circuitry and reducing the risk of brittle fracture that is common with traditional single rigid PCBs. By placing battery 4 at the rear, the center of gravity of the entire temple can be optimized while ensuring the normal function of battery 4, thereby improving wearing stability.

[0037] In summary, this application has developed a solution for smart glasses temples that balances miniaturization, high functionality, and high reliability through the protective design of the receiving cavity 32, the structural innovation of the rigid-flexible bonding plate, and the layout of the battery 4 components.

[0038] See Figure 2 The end of the temple body 3 away from the frame connection part 31 is the charging part 33. The charging part 33 has an integrated independent charging cable 331. Specifically, the charging cable 331 is a charging contact pin. The charging contact pin is a component that realizes the charging function of the battery 4. The charging contact pin is stably electrically connected to the electrodes of the battery 4 and the circuit board 5 respectively. The battery 4 and the circuit board 5 are stably electrically connected to form a charging path for the battery 4. The external charging current can be input to the circuit board 5 through the charging contact pin, and the battery 4 is charged by constant voltage and constant current through the corresponding module of the circuit board 5.

[0039] Furthermore, a diode is integrated on circuit board 5. The anode of the diode is electrically connected to the positive terminal of the charging contact pin, and the cathode of the diode is electrically connected to the positive power input terminal of circuit board 5. When the external charging base is connected in the correct direction, the diode conducts in the forward direction, and the charging current can flow normally into the charging circuit. When the external charging base is connected in the reverse direction, the diode is reverse cut off, which can directly cut off the charging circuit, thereby realizing reverse connection protection of the charging circuit and avoiding faults such as over-discharge of battery 4 and burnout of chip on circuit board 5 due to reverse charging polarity.

[0040] See Figure 3 and Figure 4 Smart glasses require wireless communication signal transmission and automatic wearing status recognition. If this is achieved through additional wiring or external modules, it will occupy the limited space inside the temples. At the same time, the connection method of traditional external modules is susceptible to vibration, which can lead to poor contact and affect functional stability.

[0041] To this end, antenna spring pins 512 and wear-sensing spring pins 511 are respectively provided on the front and back of the rigid circuit board PCB 51. Specifically, a wear-sensing FPC 321 is provided on the inner surface of the side of the temple body 3 that is in contact with the human body during use, and the area of ​​the outer surface of the temple body that is in contact with the human body during use and near the ear is the wear-sensing area 34. The wear-sensing spring pins 511 and wear-sensing FPC 321 are positioned correspondingly and elastically abut against each other; an antenna FPC 322 is provided on the inner surface of the side of the temple body 3 that is away from the human body during use, and the antenna spring pins 512 and antenna FPC 322 are positioned correspondingly and elastically abut against each other. Without increasing space occupation, wireless communication and wear-sensing functions are realized simultaneously, improving the functional integration and ease of use of the temple.

[0042] Both the wear-sensing FPC321 and the antenna FPC322 are electrically connected to the rigid circuit board PCB51 and fixed with insulating adhesive, ensuring stable mechanical installation and avoiding electrical interference with the temple body 3. The antenna spring 512 and the wear-sensing spring 511 are integrally formed from a highly conductive elastic metal material, including a base and an elastic contact portion with an arc-shaped protrusion. After installation, the elastic contact portion deforms under pressure, generating a continuous preload on the conductive sheet, ensuring reliable contact even under vibration. The base portions of both the antenna spring 512 and the wear-sensing spring 511 are connected to the corresponding circuits on the rigid circuit board PCB51 via soldering, respectively connecting to the sensing signal processing unit and the wireless communication module.

[0043] In terms of functionality, the antenna spring 512 and the antenna FPC322 together constitute the antenna system. The antenna FPC322, as the antenna radiator, is responsible for transmitting and receiving wireless signals, improving communication distance and transmission stability. Simultaneously, the wear-sensing spring 511 works in conjunction with the wear-sensing FPC321 to achieve intelligent status detection and power management. When the user wears the glasses, the human body contacts the sensor on the outside of the conductive sheet, forming a complete grounding loop. The generated sensing signal triggers the system to immediately enter working mode. Furthermore, because the wear-sensing area 34 is located near the base of the ear, this allows for more accurate wear sensing. When the glasses are removed, the loop signal disappears, and the system automatically switches to sleep mode. Through the structure of the wear-sensing FPC321 and wear-sensing spring 511, not only is automatic power on / off functionality achieved, but the necessity of setting up independent physical buttons is also eliminated, thereby further optimizing the internal space layout and making the overall structure more compact and rational.

[0044] See Figure 6 Functional module 6, as the core component for smart glasses to realize voice interaction, audio output and status feedback, includes a front microphone 61, a rear microphone 62 and a speaker 63.

[0045] The front microphone 61 and the rear microphone 62 are respectively fixedly mounted on both ends of the front flexible circuit board FPC 52 of the temple. Specifically, the front microphone 61 is located on the side of the front flexible circuit board FPC 52 near the frame connection part 31. This position is closer to the mouth when the user wears the temple, which can effectively shorten the propagation path of the voice signal and improve the clarity of voice acquisition. The rear microphone 62 is located on the side of the front flexible circuit board FPC 52 near the rigid circuit board PCB 51, forming a reasonable distance from the front microphone 61.

[0046] The speaker 63, serving as an audio output component, is installed in the area between the front microphone 61 and the rear microphone 62. This area corresponds to the position where the temples of the glasses are close to the back of the user's ears when worn, allowing the audio signal to be transmitted more directly to the ear canal and improving the listening experience.

[0047] By integrating the front microphone 61, rear microphone 62, and speaker 63 into a reasonable area of ​​the front flexible circuit board FPC52, the reliability of voice interaction, audio output and other functions is ensured, and a compact layout of each functional component is achieved.

[0048] See Figure 3 and Figure 5 In terms of operation, the front flexible circuit board FPC52 is fixed with a touch spring 521 on the side of the body facing away from the human body when in use, and the temple body 3 is provided with a temple touch switch 21 on the outer surface of the side away from the human body when in use. The temple touch switch 21 and the touch spring 521 are in corresponding positions. More specifically, the temple touch switch 21 is located in the area in front of the speaker 63. The temple touch switch 21 realizes a variety of preset functions through the vibration generated by the user's touch action.

[0049] Specifically, the touch pin 521 includes a fixed end connected to the front-end flexible circuit board FPC 52 and a vibration-sensing end. The fixed end is connected to the front-end flexible circuit board FPC 52 by soldering. The temple touch switch 21 is a specific area on the outer side of the temple body 3 away from the human body when in use, corresponding to the touch pin 521. The speaker 63 has a raised structure, and the speaker 63 forms a protrusion at the corresponding installation position of the temple body 3. Because the protrusion is obvious, in actual use, when the user does not need to perform touch operation visually, the finger sliding on the surface of the temple body 3 will be blocked by the protrusion, and the position where the finger is close to the blocking position of the speaker 63 corresponds to the touch area of ​​the temple touch switch 21, thus making it convenient for the user to quickly complete various operation commands by sliding or tapping.

[0050] When the user touches the temple touch switch 21 during operation, the pressure of the finger causes the temple touch switch 21 to undergo mechanical deformation, which in turn causes the touch spring 521 to undergo mechanical deformation. The touch spring 521 converts the mechanical vibration into an electrical signal through the piezoresistive effect. The electrical signal is transmitted through the flexible circuit board to the rigid circuit board PCB 51 for processing, and then triggers the corresponding preset function.

[0051] See Figure 7 The core chipset 513 serves as the core for data processing, signal transmission, and motion sensing in smart glasses. Specifically, it includes a Bluetooth main control chip 5131, a storage chip 5132, and a gyroscope chip 5133, all of which are fixedly mounted on a rigid circuit board PCB 51.

[0052] Specifically, the Bluetooth master control chip 5131 is soldered and fixed to the central area of ​​the rigid circuit board PCB 51 to facilitate short-path connections between the Bluetooth master control chip 5131 and other chips and peripheral circuits, reducing signal transmission loss. The core functions of the Bluetooth master control chip 5131 include: establishing a stable wireless connection with external terminal devices (such as mobile phones and tablets) through the radio frequency module to achieve bidirectional transmission of voice data, audio signals and control commands; acting as the main controller to uniformly control the functional modules 6 such as microphone, speaker 63, and indicator lights on the front-end flexible circuit board FPC 52; and integrating a power management unit to regulate the voltage of the battery 4, provide a stable operating voltage for other chips, and monitor the power supply status in real time.

[0053] The storage chip 5132 is primarily used to store data for the smart glasses. During operation, the storage chip 5132 works in conjunction with the Bluetooth master control chip 5131: when the device powers on, the Bluetooth master control chip 5131 reads data from the storage chip 5132 and loads it; while the device is running, the storage chip 5132 stores user preference settings and other data in real time; when the device undergoes firmware upgrades, the Bluetooth master control chip 5131 first temporarily stores the upgrade package in the storage chip 5132, and then completes the local upgrade operation. If an abnormal interruption occurs during the upgrade process, the original firmware can be restored from the backup partition of the storage chip 5132, improving the reliability of the system upgrade.

[0054] The gyroscope chip 5133 establishes a communication connection with the Bluetooth master control chip 5131, which can capture the subtle movements of the user's head.

[0055] The data collected by the gyroscope chip 5133 is processed by the Bluetooth main control chip 5131 to realize a number of intelligent functions: First, head posture control, users can make and receive calls and switch songs by nodding or shaking their heads, without manual touch control; Second, wearing detection, when the chip detects that the temple of the glasses has changed from being worn to being removed, it automatically triggers the screen sleep and Bluetooth disconnection functions to reduce power consumption.

[0056] In addition to the core chipset 513 mentioned above, the rigid circuit board PCB 51 also has a power management unit and indicator lights. The power management unit is the core of power regulation for the temple, and its main functions include: voltage regulation, converting the voltage output by the battery 4 into the working voltage adapted to each component, avoiding chip burnout and functional module 6 failure due to voltage fluctuations; charging management, working with the charging cable 331 and diodes to achieve constant voltage and constant current charging of the battery 4, and automatically cutting off the charging circuit after the battery 4 is fully charged to prevent overcharging damage; and power consumption control, monitoring the operating power consumption of each component in real time, and automatically reducing the power supply of non-essential components when the system enters sleep mode, effectively extending the battery life of the battery 4.

[0057] The indicator light is a status feedback component on the temple of the glasses. It is electrically connected to components such as the power management unit and the Bluetooth main control chip 5131. It conveys device operating information to the user through different light signals, such as power-on status, connection status, battery level, and charging status.

[0058] The temple body 3, as the foundation of the entire temple, can have two specific structural implementations. The first implementation is as follows: the temple body 3 includes a shell 1 and a cover 2. The shell 1 has a concave cross-section and an internal cavity. The side of the shell 1 with the cavity provides a mounting base for various functional components. The cover 2 is detachably assembled to one side of the shell 1. The shell 1 and the cover 2 together form a receiving cavity 32 and constitute the temple body 3. This split structure facilitates later inspection and maintenance of the internal electronic components. When it is necessary to replace or repair components such as the circuit board 5 and the battery 4, only the cover 2 needs to be removed, greatly improving maintenance convenience.

[0059] The second embodiment of the temple body 3 is as follows: The temple body 3 includes a front temple component and a rear temple component. Specifically, the front temple component is a hollow, flat structure with openings at both ends. The rear temple component is a shell structure with one end open and extending inward to form a cavity. The opening of the rear temple component is detachably connected to one end of the front temple component. The front temple component and the rear temple component together form a receiving cavity 32 and constitute the temple body 3. This embodiment, through this segmented design, allows for flexible adjustment of the component layout according to the needs of different functional areas. For example, the circuit board 5 can be arranged in the front temple component area, and the power supply components such as the battery 4 can be arranged in the rear temple component area, further optimizing the utilization rate of the internal space of the temple.

[0060] This application also discloses a smart glasses, which includes the temples mentioned in the foregoing embodiments. The specific structure of the temples has been described in the foregoing embodiments and will not be repeated here.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
