Description

Technical Field

[0001] This application belongs to the field of smart glasses technology, and particularly relates to a temple and smart glasses. Background Technology

[0002] With the development of consumer electronics and the metaverse industry, smart glasses have become the next generation of core wearable terminals after smartphones and smartwatches. Their core development trends focus on three major directions: extreme lightweighting, modular detachability, and multi-scenario adaptation.

[0003] In one scenario, the glasses employ a split temple design, where each temple houses a functional module, with no electrical connection between them. The frame serves as the mechanical link. In this case, how to coordinate the management of the state of the functional modules within the left and right temples is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] In a first aspect, embodiments of this application provide a temple of a pair of glasses, comprising: a first housing forming a first receiving cavity; a first power supply unit disposed within the first receiving cavity for supplying power to a first wireless control unit and a first processor disposed within the first receiving cavity; the first wireless control unit disposed within the first receiving cavity and electrically connected to the first power supply unit for controlling the first power supply unit to supply power to or stop supplying power to the first processor when receiving a first control signal, and sending a second control signal to another temple, the second control signal being used to trigger the other temple to stop supplying power to or supply power to the second processor within the other temple.

[0005] In the solution provided in this application embodiment, a first wireless control unit and a first power supply unit are built into a first receiving cavity within the first housing of the temple. The first power supply unit is used to supply power to the first wireless control unit and a first processor disposed in the first receiving cavity. In scenarios where the first power supply unit does not supply power to the first processor, a complete hard power-off can be achieved. Furthermore, the temple has an independent power supply, eliminating the need for electrical connections between temples. Based on this, by utilizing the first wireless control unit of one temple to communicate with the other temple, the temple can synchronously control the first power supply unit to supply power to or stop supplying power to the first processor when it detects a first control signal, and send a second control signal to the other temple. That is, the first control signal detected by one temple synchronously controls the power supply units in both temples to supply power to or disconnect power to the processors in their respective temples. Therefore, this solution can achieve synchronous control of power supply on / off in scenarios where the two temples adopt a completely separate temple architecture, improving the human-machine interface experience.

[0006] Secondly, embodiments of this application provide a temple of a pair of glasses. The temple includes a second housing, the second housing forming a second receiving cavity. The temple further includes: a second wireless control unit disposed within the second receiving cavity; a second power supply unit disposed within the second receiving cavity; the second power supply unit being used to supply power to at least a second processor disposed within the second receiving cavity; the second wireless control unit being electrically connected to the second power supply unit; the second wireless control unit being configured to: receive a second control signal from the first temple, and, in response to the second control signal, control the second power supply unit to supply power to or de-supply power to the second processor.

[0007] In this solution, a second wireless control unit and a second power supply unit are arranged within the second receiving cavity of the second housing of the temple. The second power supply unit is used to power at least the second processor located within the second receiving cavity. Through this power architecture design, the temple has an independent power control circuit, enabling it to have autonomous power supply and power management capabilities, eliminating the need for electrical connections between temples. Furthermore, by utilizing the second wireless control unit of the temple to communicate with the first wireless control unit of the first temple and receive a second control signal, the temple can power on or power off the second processor based on the triggering of the second control signal. This allows for power supply or power off control of the second processor in a scenario where both temples are completely separate, enabling the first temple to control the power supply or power off of the second processor in the other temple, thus improving the human-machine interface experience.

[0015] Furthermore, in the description of this application, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0016] Currently, smart glasses can adopt a completely separate temple architecture, meaning there is no electrical connection between the left and right temples. Instead, each temple uses an independent power module to power the application system installed within its respective temple. However, in this completely separate temple architecture, the synchronous on / off control of the power supply to the application system in both temples is a technical problem that urgently needs to be solved.

[0017] Based on this, the temple provided in this application provides a first wireless control unit and a first power supply unit built into the first receiving cavity of the first housing of the temple. By using the first wireless control unit of the temple to communicate with the other temple, the temple can synchronously control the first power supply unit to supply power to or stop supplying power to the first processor when it detects a first control signal, and send a second control signal to the other temple. This enables synchronous control of the power supply in the two temples to be turned on or off in scenarios where the two temples adopt a completely separate temple architecture, thereby improving the human-computer interaction experience.

[0018] Since the power supply circuit between the first power supply unit and the first processor in this embodiment is turned on or off by the first wireless control unit, the physical power-off of the first processor can be achieved in the disconnection scenario.

[0019] Before introducing the temples provided in the embodiments of this application, we will first introduce the smart glasses involved in the embodiments of this application.

[0020] like Figure 1 As shown, the smart glasses may include a first temple 101, a second temple 102, and a frame 103. Optionally, the frame 103 may be detachably or fixedly connected to the first temple 101 and the second temple 102.

[0021] The frame 103 contains a lens 104. In one case, the lens 104 is equipped with a waveguide sheet, which can be used to display information such as text, pictures, information bars, and videos.

[0022] In this embodiment of the application, in order to achieve that there is no electrical connection between the first temple 101 and the second temple 102, the first temple 101 and the second temple are respectively equipped with independent power supply units to power the first processor in the first temple 101 and the second processor in the second temple 102.

[0023] In one case, the first temple 101 and the second temple 102 may further include one or more of the following devices: an audio component, a sensor, etc., and the power supply unit may also supply power to the audio component and the sensor.

[0024] For example, the first processor and the second processor can be a system on chip (SOC), or a processing chip such as a GPU (Central Processing Unit), NPU (Graphics Processing Unit), ISP (Image Signal Processor), or VPU (Neural Processing Unit). This application does not limit the specific processor to these processors.

[0025] The audio component is used to realize voice interaction and audio playback. The audio component includes at least a microphone, an audio codec circuit, and a sound-generating element.

[0026] Sensors are used to detect a user's wearing status, posture, or environmental information. For example, sensors may include inertial measurement units (IMUs) (such as accelerometers or gyroscopes), proximity sensors, ambient light sensors, Hall effect sensors, etc.

[0027] like Figure 2 The diagram shown is a structural schematic of a temple provided in an embodiment of this application. The temple may be a first temple 101, including: a first housing, a first power supply unit 202, and a first wireless control unit 201.

[0028] The first housing has a first receiving cavity, in which the first power supply unit 202, the first processor 204 and the first wireless control unit 201 are disposed.

[0029] The first power supply unit 202 is used to supply power to the first wireless control unit 201 and the first processor 204.

[0030] The first wireless control unit 201 is electrically connected to the first power supply unit 202 and is used to control the first power supply unit 202 to supply power to or stop supplying power to the first processor 204 when a first control signal is received, and to send a second control signal to another temple (e.g., the second temple 102). The second control signal is used to trigger the second temple 102 to supply power to the second processor 304 within the second temple 102 (i.e., perform a power-on operation) or stop supplying power (i.e., perform a power-off operation).

[0031] For example, the second control signal can be a power-down command, which instructs the second processor 304 to perform a power-down operation. The second control signal can also be a power-on command, which instructs the second processor 304 to perform a power-on operation.

[0032] In this embodiment, performing a power-down operation on the processor can be replaced by turning off the power supply circuit between the power supply unit and the processor, and performing a power-on operation on the processor can be replaced by turning on the power supply circuit between the power supply unit and the processor. Further details will not be provided below.

[0033] In this embodiment, the first control signal and the second control signal can be the same control signal, namely, a switch signal indicating power supply or power off detected by the first temple. Alternatively, the second control signal can be a control signal generated by the first temple 101 after detecting the first control signal; this embodiment does not limit the specific control signal.

[0034] In the solution provided in this application embodiment, a first wireless control unit and a first power supply unit are integrated into a first receiving cavity within the first housing of the temple. The first power supply unit supplies power to the first wireless control unit and a first processor disposed within the first receiving cavity. In scenarios where the first power supply unit does not supply power to the first processor, physical power-off of the first processor can be achieved. Furthermore, each temple has an independent power supply, eliminating the need for electrical connections between temples. Based on this, by utilizing the first wireless control unit of one temple to communicate with the other temple, the temple can synchronously control the first power supply unit to supply power to or stop supplying power to the first processor when a first control signal is detected, and can also send a second control signal to the other temple. This enables synchronous control of power supply on / off in both temples in scenarios where the two temples employ a completely separate temple architecture, improving the human-machine interface experience.

[0035] In one possible embodiment of this application, the first temple 101 may further include a first power management unit 203, disposed within the first receiving cavity. The first power management unit 203 is connected to the first power supply unit 202, and is also connected to the first wireless control unit 201 and the first processor 204. The first power supply unit 202 is used to provide power voltage. The first power management unit 203 is used to convert the power voltage into the operating voltage of the first wireless control unit 201 and the operating voltage of the first processor 204.

[0036] The first wireless control unit 201 is configured to, in response to a first control signal, control the first power management unit 203 to either stop supplying power to the first processor 204 or supply power to the first processor 204.

[0037] It is understandable that the first power management unit 203 can provide permanent power to the first wireless control unit 201, while providing power to the first processor 204 on demand.

[0038] In one possible embodiment of this application, the first temple 101 further includes a first switch 205 disposed on the first housing. The first switch 205 is used to generate a first control signal. The first switch 205 is electrically connected to the first wireless control unit 201.

[0039] Specifically, the first wireless control unit 201 is used to collect the first trigger signal of the first switch 205 and use the first trigger signal as the first control signal.

[0040] Optionally, one end of the first switch 205 protrudes from the outer surface of the first housing. The other end of the first switch 205 is located inside the first receiving cavity of the first housing and is electrically connected to the first wireless control unit 201, so that the user can trigger the first wireless control unit 201 to enter pairing mode or perform other control operations by operating the first switch 205.

[0041] In one specific implementation of this application, the first switch 205 may be a DIP switch. For example, the first switch may have multiple positions or toggle settings. By toggling the DIP switch to a preset position or setting, the user can input a specific combination of level signals as a first control signal to the first wireless control unit 201. For example, the first control signal may be a first level signal or a second level signal. One of the first and second level signals is a high-level signal, and the other is a low-level signal. One of the first and second level signals corresponds to a first toggle position or first setting of the first switch 205, and the other level signal corresponds to a second toggle position or second setting of the first switch 205. For example, the first level signal indicates that the first switch 205 is in the first position or first toggle position (e.g., the DIP switch is turned to the ON position), and the second level signal indicates that the first switch 205 is in the second position or second toggle position (e.g., the DIP switch is turned to the OFF position).

[0042] It is understood that the first switch 205 may also be a mechanical button, a touch button, a slide switch or a combination thereof, and this application embodiment does not limit this.

[0043] Taking the first switch 205 as a mechanical button as an example, when a user presses the mechanical button once, a first-level signal is triggered. Pressing the button again triggers a second-level signal, or vice versa. For instance, if pressing the button once reduces the distance between the button and the first wireless control unit 201 (i.e., the button moves closer to the control unit 201), the first-level signal is triggered, indicating the button is pressed. If pressing the button again increases the distance between the button and the control unit 201 (i.e., the button moves away from the control unit 201), the second-level signal is triggered.

[0044] Taking the first switch 205 as a slide switch as an example, when the user triggers the slide switch to initially be in position A, when the user triggers the slide switch to move to position B, a first level signal is triggered. When the user triggers the slide switch again to move from position B to position A, a second level signal is triggered.

[0045] Taking the first switch 205 as a trigger button as an example, in response to the touch operation of turning on, the trigger button outputs a first level signal, and in response to the touch operation of turning off, the trigger button outputs a second level signal.

[0046] For example, the first wireless control unit 201 may transmit the second control signal in a broadcast or unicast manner.

[0047] In one possible implementation of this application, the first power supply unit 202 may be a battery, which may be a rechargeable battery, such as a lithium polymer battery, lithium-ion battery, or button cell battery.

[0048] In one possible embodiment of this application, such as Figure 3 or Figure 4 As shown, a first power management unit 203 is also disposed in the first receiving cavity of the first housing. The first power management unit 203 is electrically connected to the first power supply unit 202, and is also electrically connected to the first wireless control unit 201 and the first processor 204.

[0049] The first power management unit 203 is used to convert the power supply voltage provided by the first power supply unit 202 into the operating voltage for powering the first wireless control unit 201 and the first processor 204, respectively.

[0050] In one possible embodiment of this application, the first power management unit 203 and the first power supply unit 202 can be implemented by two independent devices, or they can be implemented by a device that integrates power management and power supply. This application does not limit the implementation in this way.

[0051] In one possible embodiment of this application, such as Figure 3 As shown, the first power management unit 203 has a controllable output channel 2031 for connecting to the first processor 204. The first wireless control unit 201 is configured to, in response to a first control signal, control the controllable output channel 2031 to be in an enabled or disabled state. When the controllable output channel 2031 is in the enabled state, power is supplied to the first processor 204. When the controllable output channel 2031 outputs a disabled state, power is stopped from supplying power to the first processor 204.

[0052] When the controllable output channel 2031 is enabled, the first power supply circuit between the first power management unit 203 and the first processor 204 is turned on, so that the first power supply unit 202 supplies power to the first processor 204. When the controllable output channel 2031 is disabled, the first power supply circuit is turned off, so that the first power supply unit 202 stops supplying power to the first processor 204.

[0053] In one possible implementation of this application, the first control signal is a first-level signal, and the first wireless control unit 201 is configured to: in response to the first control signal, control the controllable output channel 2031 to be in an enabled state, that is, the corresponding first switch 205 is in an OFF state. Alternatively, if the first control signal is a second-level signal, the first wireless control unit 201 is configured to: in response to a first trigger signal, control the controllable output channel 2031 to be in an disabled state, that is, the corresponding first switch 205 is in an ON state.

[0054] In one possible implementation of this application, the first power management unit 203 further has an output channel 2032, which is connected to the first wireless control unit 201. The first power management unit 203 can provide operating voltage to the first wireless control unit 201 through the output channel 2032.

[0055] In one possible implementation of this application, the first power management unit 203 may include a direct current-to-direct current (DC-DC) converter and a low dropout regulator (LDO).

[0056] It is worth noting that the power management unit involved in the embodiments of this application can also be implemented using other circuits or structures. These will not be listed one by one here. However, any power management circuit or chip that can convert the power voltage provided by the first power supply unit 202 into the working voltage required by the first wireless control unit 201 and the first processor 204 can be used as the power management unit in the embodiments of this application.

[0057] In one possible embodiment of this application, such as Figure 4 As shown, the first temple 101 further includes a first switching circuit 206 located within the first receiving cavity. The first switching circuit 206 is controlled by a first wireless control unit 201. A second terminal of the first switching circuit 206 is connected to a first power supply unit 202. For example, the second terminal of the first switching circuit 206 can be connected to the first power supply unit 202 via a first power management unit 203. A third terminal of the first switching circuit 206 is connected to a first processor 204. The first wireless control unit 201 is configured to, in response to a first control signal, control the first switching circuit 206 to be turned on or off to supply power to or de-supply power to the first processor 204 (i.e., power off).

[0058] In one possible implementation of this application, the first switching circuit 206 in this embodiment can be a metal-oxide-semiconductor field-effect transistor (MOS) switching circuit. For example, the first switching circuit 206 uses a low on-resistance P-channel MOS transistor. The gate (i.e., the first terminal) of the MOS transistor is directly connected to the control input / output (I / O) interface of the first wireless control unit 201, the source (i.e., the second terminal) of the MOS transistor is connected to the main power input terminal of the first power management unit 203, and the drain (i.e., the third terminal) of the MOS transistor is connected to the first processor 204.

[0059] In one possible implementation of this application, the first wireless control unit 201 controls the first switching circuit 206 to turn on in response to the first control signal being a first level signal, so as to supply power to the first processor 204, or controls the first switching circuit 206 to turn off in response to the first control signal being a second level signal, so as to stop supplying power to the first processor 204.

[0060] For example, the first wireless control unit 201 can output a third-level signal or a fourth-level signal to the first switching circuit 206. One of the third-level signal and the fourth-level signal is a high-level signal, and the other is a low-level signal. One of the third-level signal and the fourth-level signal is used to trigger the first switching circuit 206 to turn on, and the other signal is used to trigger the first switching circuit 206 to turn off.

[0061] It is understandable that when the first switch 205 is in the OFF state, the first switch circuit 206 is in the open state. When the first switch 205 is in the ON state, the first switch circuit 206 is in the on state.

[0062] In one possible implementation of this application, when the first control signal is a first-level signal, the first wireless control unit 201 is specifically configured to: output a second trigger signal as the second control signal or the second control signal includes the second trigger signal, wherein the second trigger signal indicates power supply to the second processor 304. When the first control signal is a second-level signal, the first wireless control unit 201 is specifically configured to: use a third trigger signal as the second control signal or send a second control signal including the third trigger signal. The third trigger signal indicates power supply to the second processor 304 to be stopped.

[0063] For example, one of the third trigger signal and the second trigger signal can be a high-level signal and the other can be a low-level signal. Alternatively, the third trigger signal and the second trigger signal can be indicators composed of at least one bit. For example, the third trigger signal can be 1 and the second trigger signal can be 0, or the second trigger signal can be 10 and the third trigger signal can be 01, etc., and the embodiments of this application do not limit this.

[0064] For example, the first wireless control unit 201 may internally store a mapping relationship between a first level signal and a second trigger signal, and a mapping relationship between a second level signal and a third trigger signal. Thus, when the first wireless control unit 201 detects that a first level signal is acting on the first switch 205, it can use the second trigger signal as the second control signal. When the first wireless control unit 201 detects that a second level signal is acting on the first switch 205, it can use the third trigger signal as the second control signal.

[0065] In one possible implementation of this application, the second control signal further includes first verification information, which is used by the second temple 102 to verify the legitimacy of the first temple 101. If the second temple 102 verifies the legitimacy of the first temple 101 based on the first verification information, it can respond to the second control signal and execute a corresponding action. If the second temple 102 verifies the legitimacy of the first temple 101 based on the first verification information, it can refuse to respond to the second control signal. For example, the second temple 102 can verify whether the first verification information is consistent with the pairing information contained in the second temple 102, or whether there is a preset mapping relationship. If they are consistent or have a mapping relationship, it can be considered legitimate; if there is no mapping relationship and / or they are inconsistent, it is determined to be illegitimate.

[0066] For example, the first verification information may be the identification information of the first temple 101. There is a mapping relationship between the identification information of the first temple 101 and the identification information of the second temple 102. By storing the identification information with the mapping relationship, it can serve as pairing information to characterize the pairing relationship between the two, thereby enabling automatic identification and verification during subsequent assembly or communication connection. The identification information of the first temple 101 is used to identify the first temple 101. This application embodiment does not limit the identification information of the first temple 101; any information that can uniquely identify the first temple 101 can be used as the identification information. For example, the second temple 102 stores the identification information of the first temple 101 that has successfully paired with the second temple 102.

[0067] It is worth noting that the content of the first verification information can also be other implementations besides those listed above, and this application embodiment does not limit this. Any information that can be used to implement the second temple 102 to verify the legality of the first temple 101 can be regarded as the first verification information used in this application embodiment.

[0068] In one possible implementation of this application, in order to achieve the security of communication between the first temple 101 and the second temple 102, the first wireless control unit 201 is further configured to: encrypt the second control signal using an encryption key to obtain the encrypted second control signal, and to: send the encrypted second control signal.

[0069] In one possible implementation of this application, the first wireless control unit 201 stores an encryption key. For example, the first wireless control unit 201 has a storage module for storing the encryption key and / or pairing information. The pairing information is used to characterize a pairing relationship between the first temple 201 and the second temple 102. For example, the pairing information includes at least a mapping relationship between the identification information of the first temple 101 and the identification information of the second temple 102.

[0070] In this embodiment of the application, the first temple 101 and the second temple 102 are connected by wireless communication. For example, the first temple 101 establishes a wireless connection with the second temple 102 through the first wireless control unit 201.

[0071] For example, the first wireless control unit 201 has at least wireless communication functionality. For instance, the first wireless control unit 201 includes at least a radio frequency transceiver module, which can be a Near Field Communication (NFC) transceiver or a Bluetooth transceiver. In this embodiment, the first wireless control unit 201 may include a first wireless control chip, or be implemented using a first wireless control chip. The first wireless control chip may be a near field communication control chip.

[0072] For example, the near-field communication control chip may be a Bluetooth wireless control chip or a first NFC wireless control chip.

[0073] In scenarios where the first wireless control unit 201 includes an NFC transceiver, an NFC communication connection can be established between the first temple 101 and the second temple 102.

[0074] In scenarios where the first wireless control unit 201 includes a Bluetooth transceiver, a Bluetooth communication connection can be established between the first temple 101 and the second temple 102.

[0075] In one possible embodiment of this application, such as Figure 2 or Figure 3 As shown, the first wireless control unit 201 can be a chip that combines processing and wireless communication, meaning it integrates a processing module and a radio frequency transceiver module into a single chip. For example, it could be a first NFC wireless control chip or a Bluetooth wireless control chip. The first NFC wireless control chip refers to an integrated circuit that integrates a microcontroller unit (MCU) and an NFC radio frequency transceiver. The Bluetooth wireless control chip refers to a chip that integrates an MCU and a Bluetooth radio frequency transceiver. The Bluetooth wireless control chip is used to establish a Bluetooth communication connection between the first temple 101 and the second temple 102 in smart glasses, and is used to transmit control commands including first verification information, a first control signal, or a second control signal.

[0076] For example, the Bluetooth wireless control chip in the embodiments of this application may refer to a Bluetooth Low Energy (BLE) chip, such as a dedicated BLE chip for power control.

[0077] Alternatively, the first wireless control unit 201 can be a chip composed of a processing chip and a chip with wireless communication capabilities. For example, the first wireless control unit 201 can be composed of an MCU with processing capabilities and an NFC radio frequency transceiver with wireless communication capabilities. The two are physically separate, but functionally they together constitute a wireless control chip for generating and transmitting control commands including the first verification information. Alternatively, the first wireless control unit 201 can be composed of an MCU with processing capabilities and a Bluetooth radio frequency transceiver with wireless communication capabilities. The two are physically separate, but functionally they together constitute a wireless control chip for generating and transmitting control commands including the first verification information.

[0078] In one possible implementation of this application, such as Figure 2 or Figure 3As shown, the first wireless control unit 201 may include a processing module and a radio frequency transceiver module.

[0079] For example, the processing module can be an MCU, and the RF transceiver module can be a transceiver. As one example, the MCU and transceiver can be deployed on a single chip to form the first wireless control unit 201. As another example, the MCU and transceiver can be deployed independently and connected to form the first wireless control unit 201.

[0080] For example, in a scenario where the first wireless control unit 201 is a first NFC wireless control chip, the radio frequency transceiver module can be an NFC radio frequency transceiver. In a scenario where the first wireless control unit 201 is a Bluetooth wireless control chip, the radio frequency transceiver module can be a Bluetooth radio frequency transceiver.

[0081] The processing module is configured to: connect to the first switch 205, acquire a first trigger signal as a first control signal, generate a second control signal in response to the first control signal, and control the first power supply unit to supply power to or stop supplying power to the first processor 204. The radio frequency transceiver module is configured to: transmit the second control signal.

[0082] In one possible implementation of this application, the first wireless control unit 201 further includes an encryption module and / or a storage module. The storage module is used to store the encryption key, the identification information of the first temple 101, and the identification information of the second temple 102.

[0083] An encryption module is used to read the encryption key stored in the storage module to encrypt the second control signal to obtain an encrypted second control signal. The radio frequency transceiver module is configured to transmit the encrypted second control signal.

[0084] For example, the encryption module may be a hardware encryption engine. The storage module 2024 may include a one-time programmable secure storage area.

[0085] Optionally, in addition to the first processor 204, the first temple 101 may also house an audio component, a display module, and sensors. The first processor 204 is electrically connected to the audio component, display module, and sensors to control the operation or shutdown of the corresponding modules. Optionally, the audio component, display module, and sensors may also be electrically connected to the first power supply unit 202 or via a first power management unit 203. The first power management unit 203 may also convert the power supply voltage of the first power supply unit 202 into the operating voltage for the audio component, display module, and sensors.

[0086] The following will describe the specific implementation process when using the first NFC wireless control chip or the Bluetooth wireless control chip.

[0087] In one possible implementation of this application, the first wireless control unit 201 is a first NFC wireless control chip, which has a storage module. The storage module stores encryption keys and / or pairing information. The first wireless control unit 201 can read the encryption keys stored in the storage module to encrypt the second control signal, and can also read the pairing information stored in the storage module to carry the identification information of the first temple 101 in the second control signal.

[0088] In one possible implementation of this application, the first NFC wireless control chip supports card emulation mode. When the first NFC wireless control chip is configured in card emulation mode, in response to the write operation of the NFC tool, an encryption key and / or pairing information are written into the first NFC wireless control chip.

[0089] For example, the external NFC fixture can support writing encryption keys and / or pairing information over the air into the one-time programmable secure storage area of ​​the first NFC wireless control chip. This solution can realize the writing of information into the first wireless control unit 201 via NFC near-field communication.

[0090] For example, external NFC tooling can refer to a dedicated NFC reader / writer device used in a factory or for maintenance, or a device specifically designed to read and write the storage area of ​​the first temple 101.

[0091] For example, the external NFC fixture can be a single-channel NFC fixture or a dual-channel NFC fixture. When using a dual-channel NFC fixture, the dual-channel NFC fixture can simultaneously write the same set of unique true random encryption keys and / or pairing information to the OTP security areas of the wireless control chips in the first temple 101 and the second temple 102 in an over-the-air writing manner.

[0092] For example, in the scenario of replacing the first temple 101 of smart glasses, the encryption key and / or pairing information of the first temple 101 can be written to the wireless control chip of the new temple via an after-sales external NFC tool in an over-the-air writing manner, thereby completing the pairing of the new temple with the second temple 102. No shell removal or pre-reserved burning contacts are required, and the repair can be completed in a short time (e.g., 5 seconds).

[0093] In one possible embodiment of this application, the first NFC wireless control chip in the first temple 101 can enter card emulation mode upon detecting a first operation against the first switch 205.

[0094] For example, the first operation can be toggling the first switch 205 multiple times within a certain time period (e.g., 5 seconds). For instance, toggling the first switch 205 three times consecutively within 5 seconds. This solution can not only use the first switch 205 to trigger the synchronous power-on or power-off of the power supplies in the first temple 101 and the second temple 102, but also use the first switch 205 to enable the first NFC wireless control chip to enter card emulation mode.

[0095] Optionally, the first temple 101 also has a trigger switch. When a specific operation is detected on the trigger switch, the first wireless control unit 201 enters card emulation mode. For example, the specific operation could be a long press or a single click, which is not limited in this embodiment.

[0096] Optionally, in this embodiment, the NFC control chip can also be triggered to enter card emulation mode via an external NFC fixture or other device. For example, the first NFC wireless control chip constantly listens to the radio frequency (RF) field, and can enter card emulation mode once it detects an external field strength. As an example, the other device must at least have permission to operate the smart glasses. Other devices without permission to operate the smart glasses cannot trigger the first NFC wireless control chip to enter card emulation mode.

[0097] The following description will take the first wireless control unit 201 as an example of a Bluetooth wireless control chip: In one possible implementation of this application, the Bluetooth wireless control chip is further configured to interact with a host computer via a preset service to obtain at least one of the following information: encryption key, pairing information, and address information of the second temple 102 (e.g., Media Access Control (MAC) address). The address information of the second temple 102 is used to establish a Bluetooth connection between the first temple 101 and the second temple 102. In this embodiment, the address information of the temple can also serve as the identification information of the temple, and this embodiment is not limited thereto. Of course, the identification information of the temple can also be other information besides the address information of the temple.

[0098] Optionally, after the Bluetooth wireless control chip obtains one or more of the encryption key, pairing information, and the MAC address of the second temple, it can store them in the OTP security area of ​​the Bluetooth wireless control chip.

[0099] For example, a preset service could refer to a custom Generic Attribute Profile (GATT) service. By authorizing a host computer to connect to the Bluetooth wireless control chip's custom GATT service, pairing information can be written in batches without needing to burn contact points, making it suitable for rework and small-batch production scenarios.

[0100] In one possible implementation of this application, the first wireless control unit is a Bluetooth wireless control chip. A unique true random encryption key, the peer MAC address, and pairing information can be written into the OTP security area of ​​the Bluetooth wireless control chip on the first temple using a programming fixture. After writing, the OTP area is automatically locked, allowing only paired chips to establish communication. Optionally, the programming fixture can be a dual-channel or single-channel fixture. Using a dual-channel fixture allows for the simultaneous writing of the same unique true random encryption key, peer MAC address, and pairing information to both the first temple 101 and the second temple 102.

[0101] For example, an encryption key 'a', the MAC address of the second temple 102, and pairing information between the first temple 101 and the second temple 102 can be written to the OTP security area of ​​the BLE wireless control chip of the first temple 101. Similarly, an encryption key 'a', the MAC address of the first temple 101, and pairing information between the first temple 101 and the second temple 102 can be written to the OTP security area of ​​the BLE wireless control chip of the second temple 102.

[0102] In one possible implementation of this application, the first wireless control unit 201 is a Bluetooth wireless control chip, which is further configured to: when the Bluetooth wireless control chip enters pairing mode, broadcast the MAC address of the first temple 101 and obtain the MAC address of the second temple 102. Exemplarily, the Bluetooth wireless control chip is also configured to: enter pairing mode in response to a first operation on the first switch 205.

[0103] Optionally, the Bluetooth wireless control chip can also broadcast the smart glasses' device name and / or include a service UUID to indicate that it is part of the smart glasses.

[0104] The Bluetooth wireless control chip broadcasts the MAC address of the first temple 101 to facilitate the discovery of the MAC address of the first temple 101 by the second temple 102. This is the first step before establishing a Bluetooth communication connection between the two. After the second temple 102 resolves the MAC address of the first temple 101, it reads the MAC address of the peer stored in the second wireless control unit of the second temple 102. If they match, a Bluetooth wireless connection is initiated; otherwise, it is ignored. Similarly, the Bluetooth wireless control chip obtains the MAC address of the second temple 102 and reads the MAC address of the peer stored in the first wireless control unit 201 of the first temple 101. If they match, a Bluetooth wireless connection is initiated; otherwise, it is ignored.

[0105] The dual-sided chip pairing is triggered by a special operation of the DIP switch, eliminating the need for additional tooling and enabling rapid assembly of small batches of equipment. Furthermore, in scenarios involving the replacement of the first temple 101, a special operation is triggered by the DIP switch for the new temple, causing the new temple and the second temple to enter pairing mode, automatically completing information exchange and pairing. Users / after-sales personnel can operate this without specialized equipment.

[0106] like Figure 2 The diagram shows the structure of another temple (i.e., the second temple 102) provided in this embodiment of the application. The second temple 102 has a second housing, which has a second receiving cavity.

[0107] like Figure 2 As shown, the second temple 102 includes: a second wireless control unit 301 and a second power supply unit 302. The second wireless control unit 301, the second power supply unit 302, and the second processor 304 are all located within the second receiving cavity.

[0108] The second power supply unit 302 is used to supply power to at least the second processor 304.

[0109] Optionally, the second receiving cavity may further include: an audio component, a display module, sensors, etc., and the second processor 304 is electrically connected to the audio component, display module, sensors, etc., respectively to control the corresponding modules to work or stop working. Optionally, the audio component, display module, sensors, etc., are also used to electrically connect to the second power supply unit 302 or to the second power management unit 303. The first power management unit 303 is also used to convert the power supply voltage of the second power supply unit 302 into the operating voltage for powering the audio component, display module, sensors, etc.

[0110] The second wireless control unit 301, electrically connected to the second power supply unit 302, is configured to: receive a second control signal from the first temple 101, and in response to the second control signal, control the second power supply unit 302 to supply power to or de-energize the second processor 304.

[0111] For example, the second control signal indicates that a power-on operation or a power-off operation is performed on the second processor 304.

[0112] For example, if the second control signal indicates a power-on operation, which is considered a power-on command, then the second wireless control unit 301 is also configured to respond to the second control signal by controlling the second power supply unit 302 to supply power to the second processor 304. Conversely, if the second control signal indicates a power-off operation, which is considered a power-off command, then the second wireless control unit 301 is also configured to respond to the second control signal by controlling the second power supply unit 302 to de-energize the second processor 304.

[0113] The structures and implementations of the second power supply unit 302, the second processor 304, and the second power management unit 303 in the embodiments of this application can be referred to the specific implementations of the first power supply unit 202, the first processor 204, and the first power management unit 203 described above, and will not be repeated here.

[0114] In one possible embodiment of this application, the first temple 101 and the second temple 102 are paired. For example, the first temple 101 stores information indicating a pairing relationship with the second temple 102, and the second temple 102 stores information indicating a pairing relationship with the first temple 101. Based on the pairing relationship between them, the first temple 101 and the second temple 102 can establish a wireless communication connection and exchange information.

[0115] In one possible implementation of this application, such as Figure 3 As shown, the second temple 102 provided in this embodiment may further include a second power management unit 303 disposed within the second receiving cavity and electrically connected to the second power supply unit 302. The first power management unit 303 is also electrically connected to the second wireless control unit 301 and the second processor 304; the second power management unit 303 is used to convert the power supply voltage of the second power supply unit 302 into the operating voltage of the second wireless control unit 301 and the second processor 304; The second wireless control unit 301 is configured to, in response to a second control signal, control the second power management unit 303 to stop or supply power to the second processor 304.

[0116] In one possible implementation of this application, such as Figure 4As shown, the second temple 102 further includes a second switch circuit 305 connected in series with the second power supply circuit. The second switch circuit 305 is controlled by the second wireless control unit 301, that is, the first terminal of the second switch circuit 305 is connected to the input / output interface of the second wireless control unit 301. The third terminal of the second switch circuit 305 is connected to the second processor 304, and the second terminal of the second switch circuit 305 is connected to the second power management unit 303. The second wireless control unit 301 is configured to control the second switch circuit 305 to be turned on or off in response to a second control signal, so as to realize that the first power supply unit supplies power to or stops supplying power to the second processor 304.

[0117] In one possible implementation of this application, the second control signal may include or be a second trigger signal. The second wireless control unit 301 is configured to output a high-level signal to the second switching circuit 305 in response to the second trigger signal. The second switching circuit 305 is turned on based on the triggering of the high-level signal, and the second power supply unit 302 supplies power to the second processor 304. Alternatively, the second control signal may include or be a third trigger signal. The second wireless control unit 301 is configured to output a low-level signal to the second switching circuit 305 in response to the third trigger signal. The second switching circuit 305 is turned off based on the triggering of the low-level signal, thereby stopping the second power supply unit 302 from supplying power to the second processor 304.

[0118] For details on the implementation of the second switch circuit 305, please refer to the implementation of the first switch circuit 206 described above; it will not be repeated here.

[0119] In one possible embodiment of this application, such as Figure 3 As shown, the second power management unit 303 has a controllable output channel 3031 for connecting to the second processor 304. The second wireless control unit 301 is configured to control the controllable output channel 3031 to be in an enabled or disabled state in response to a second control signal. When the controllable output channel 3031 is in the enabled state, the second power supply unit 302 supplies power to the second processor 304. When the controllable output channel 3031 outputs a disabled state, the second power supply unit 302 stops supplying power to the second processor 304.

[0120] In one possible implementation of this application, the second control signal may include or be a second trigger signal, and the second wireless control unit 301 is configured to: in response to the second trigger signal, control the controllable output channel 3031 to be in an enabled state. Alternatively, the second control signal may include or be a third trigger signal, and the second wireless control unit 301 is configured to: in response to the third trigger signal, control the controllable output channel 3031 to be in a disabled state.

[0121] It is understandable that when the first switch 205 is in the OFF state, the controllable output channel 3031 is in the disabled state. When the first switch 205 is in the ON state, the controllable output channel 3031 is in the enabled state.

[0122] In one possible implementation of this application, the second power management unit 303 further has an output channel 3032, which is connected to the second wireless control unit 301. The second power management unit 303 can provide operating voltage to the second wireless control unit 201 through the output channel 3032.

[0123] The second power management unit 303 can convert the power supply voltage provided by the second power supply unit 302 into the operating voltage of the second processor 304. The power supply voltages of the second processor 304 and the second wireless control unit 301 can be the same or different, and this embodiment does not limit this.

[0124] In one possible embodiment of this application, the second wireless control unit 301 may be a passive wireless control chip or an active wireless control chip. When a passive wireless control chip is used, the second power supply unit 302 is not electrically connected to the second wireless control unit 301 and does not need to supply power to the second wireless control unit 301. Optionally, the second power management unit 303 also does not need to be electrically connected to the second wireless control unit 301.

[0125] When an active wireless control chip is used, the second power supply unit 302 is also electrically connected to the second wireless control unit 301 to provide operating voltage to the second wireless control unit 301.

[0126] In one possible embodiment of this application, such as Figure 3 or Figure 4 As shown, the second power supply unit 302 is electrically connected to the second wireless control unit 301 through the second power management unit 303.

[0127] The second power management unit 303 is also connected to the second wireless control unit 301 and is used to convert the power supply voltage into the operating voltage of the second wireless control unit 301.

[0128] In one possible embodiment of this application, the second control signal further includes first verification information, such as the identification information of the first temple 101. The second wireless control unit 301 is specifically configured to perform a validity check based on the identification information of the first temple 101. If the validity check passes, it responds to the second control signal. If the validity check fails, it does not respond to the second control signal.

[0129] For example, the OTP security zone of the second wireless control unit 301 stores pairing information. If the second wireless control unit 301 determines that the identification information included in the first verification information is consistent with the identification information of the stored first temple 101, it can determine that the legitimacy verification has passed; otherwise, it determines that the legitimacy verification has failed.

[0130] In one possible embodiment of this application, the second wireless control unit 301 is used to receive the encrypted second control signal and to decrypt the encrypted second control signal to obtain the second control signal.

[0131] Optionally, the OTP security zone of the second wireless control unit 301 stores a decryption key. The second wireless control unit 301 can use this decryption key to decrypt the encrypted control command to obtain the control command. Optionally, the first temple 101 and the second temple 102 can use symmetric encryption, that is, the encryption key and the decryption key can be the same. Alternatively, the first temple 101 and the second temple 102 can also use asymmetric encryption, for example, the encryption key is the public key of the second temple 102, and the decryption key is the private key of the second temple 102.

[0132] Optionally, in an encrypted scenario, the second wireless control unit 301 is further configured to: use the identification information of the first temple 101 to verify the legitimacy of the second control signal obtained from the decryption operation.

[0133] In one possible embodiment of this application, the second wireless control unit 301 is in a low-power detection state, that is, it is only responsible for real-time scanning of the encrypted second control signal or second control signal of the paired first temple 101, NFC tool triggering, etc., and is in a standby state without actively transmitting signals, ready to be woken up at any time.

[0134] For example, the second wireless control unit 301 is in a low-power detection state. After being woken up, it enters the working mode and controls the second processor 304 to be powered on or off.

[0135] In one possible embodiment of this application, the second wireless control unit 301 is configured to enter an operating mode in response to a second control signal and control the power supply or power cut-off of the second processor 304.

[0136] In one embodiment, the second wireless control unit 301 is further configured to automatically and immediately or after a preset time return to a low-power detection state after the second processor 304 is powered off.

[0137] In another embodiment, after the second wireless control unit 301 controls the second processor 304 to be powered off, it is triggered by the first wireless control unit 201 to return to the low-power detection state.

[0138] In one possible embodiment of this application, a second switch 306 is further provided on the second housing. One end of the second switch 306 is located outside the second housing, and the other end is located inside the second receiving cavity of the second housing for electrical connection with the second wireless control unit 301. The second wireless control unit 301 is also used to collect a fourth trigger signal generated by the second switch 306, and to control the second power supply unit 302 or the second power management unit 303 to supply or de-energize the second processor 304 in response to the fourth trigger signal.

[0139] The description of the second switch 306 can be found in the description of the first switch 205 above, and will not be repeated here.

[0140] For example, if the fourth trigger signal is a high-level signal, the second wireless control unit 201 controls the second power supply unit 302 or the second power management unit 303 to supply power to the second processor 304. For example, if the fourth trigger signal is a low-level signal, the second wireless control unit 201 controls the second power supply unit 302 or the second power management unit 303 to cut off power to the second processor 304.

[0141] The specific implementation of the second wireless control unit 201 controlling the second power supply unit 302 or the second power management unit 303 to cut off the power to the second processor 304 can be referred to the corresponding description in the above embodiments, and will not be repeated here.

[0142] This solution allows the second switch 306 to power on or off the second processor 304 in the second temple 102 on one side without affecting the control logic in the first temple 101.

[0143] In one possible embodiment of this application, the second wireless control unit 301 may be a short-range communication control chip.

[0144] For example, the near-field communication control chip can be a first NFC wireless control chip. When the first NFC wireless control chip is configured in card emulation mode, at least one of the following information is written into the first NFC wireless control chip via an external NFC tool: a decryption key and pairing information.

[0145] For a specific implementation, please refer to the process described above of writing the encryption key and pairing information to the first NFC wireless control chip in the first wireless control unit 201, which will not be repeated here.

[0146] In one possible embodiment of this application, the second wireless control unit 301 is a Bluetooth wireless control chip, which is further configured to interact with a host computer through a preset service to obtain at least one of the following information: encryption key, pairing information, and address information of the first temple 101. The MAC address of the first temple 101 is used to establish a Bluetooth connection between the first temple 101 and the second temple 102.

[0147] For a detailed explanation of the implementation, please refer to the process described above where the host computer writes the encryption key, the MAC address of the first temple 101, and pairing information to the Bluetooth wireless control chip in the first wireless control unit 201. This will not be elaborated upon here.

[0148] In one possible embodiment of this application, the second wireless control unit 301 is a Bluetooth wireless control chip, which is further configured to: control the Bluetooth wireless control chip to enter a pairing mode in response to a second operation of the second switch 306 set on the second temple 102; when the Bluetooth wireless control chip enters the pairing mode, the Bluetooth wireless control chip is used to broadcast the MAC address of the second temple 102 and obtain the MAC address of the first temple 101.

[0149] Optionally, the Bluetooth wireless control chip can also broadcast the smart glasses' device name and / or include a Universally Unique Identifier (UUID) to indicate that it is part of the smart glasses.

[0150] The function and purpose of the Bluetooth wireless control chip in the second temple 102 broadcasting the MAC address of the second temple 102 can be referred to the function and purpose of the Bluetooth wireless control chip in the first temple 101 broadcasting the MAC address of the first temple 101, as described above, and will not be repeated here.

[0151] In one possible implementation of this application, the first wireless control unit 201 in the first temple 101 and the second wireless control unit 301 in the second temple 102 are both first NFC wireless control chips or both are Bluetooth wireless control chips.

[0152] For example, the first wireless control unit 201 in the first temple 101 and the second wireless control unit 301 in the second temple 102 both use the first NFC wireless control chip. The two transmit or encrypt control signals through near-field communication technology with a frequency of 13.56MHz.

[0153] For example, the first wireless control unit 201 in the first temple 101 and the second wireless control unit 301 in the second temple 102 both use Bluetooth wireless control chips, and the two achieve encrypted transmission of control signals through low-power Bluetooth wireless communication.

[0154] It is worth noting that the radio frequency transmitting unit in the first wireless control unit 201 of this application embodiment is not only used to send control commands to the second wireless control unit 301, but also to upload locally collected voice, images, videos, etc., to the cloud or mobile devices, so that the cloud or mobile devices can perform real-time translation, object recognition, scene understanding, etc., and then return the results to the smart glasses for display. The radio frequency transmitting unit in the second wireless control unit 301 can also be used to upload locally collected voice, images, videos, etc., to the cloud or mobile devices, so that the cloud or mobile devices can perform real-time translation, object recognition, scene understanding, etc., and then return the results to the smart glasses for display. Of course, the first wireless control unit 201 and the second wireless control unit 301 can also be linked with other smart devices, such as VR / AR head-mounted display devices, smartwatches, smart headphones, and other terminals for data synchronization and scene linkage.

[0155] The following description uses the example of the first wireless control unit 201 as the first NFC wireless control chip, the second wireless control unit 301 as the second NFC wireless control chip, the first switching circuit 206 as the first MOSFET switching circuit, and the second switching circuit 305 as the second MOSFET switching circuit to illustrate the synchronous power-on / power-off process of the first temple 101 and the second temple 102 in smart glasses: 1. Synchronous Power-On Workflow: The user switches the first switch 205 of the first temple 101 to the "On" position. The first switch 205 outputs a high-level trigger signal to the first NFC wireless control chip 1 as the first control signal. After the MCU in the first NFC wireless control chip receives the high-level trigger signal, it retrieves the encryption key from the OTP security zone in response to the high-level trigger signal. The first NFC wireless control chip uses the encryption key to encrypt the power-on command (i.e., the second control signal), generating an encrypted power-on command, and sends a broadcast signal through the NFC radio frequency module. This broadcast signal includes the encrypted power-on command. The power-on command is used to instruct the second processor 304 to perform a power-on operation. The first NFC wireless control chip also responds to the high-level trigger signal by synchronously outputting a high-level signal to the first MOS transistor switching circuit. Therefore, the first MOS transistor switching circuit is turned on, and the first power supply unit 202 supplies power to the first processor 204, which then powers on and starts up. The second NFC wireless control chip, in a low-power detection state, receives an encrypted power-on command from the first temple 101. Responding to the encrypted power-on command, it reads the decryption key from the OTP security zone using its built-in hardware encryption engine to decrypt the encrypted power-on command, obtaining the power-on command. It then uses the identification information of the first temple 101 stored in the OTP security zone to verify the legitimacy of the power-on command. After successful verification, the second NFC wireless control chip responds to the power-on command by outputting a high-level signal to the second MOS transistor switching circuit. The second MOS transistor switching circuit is synchronously turned on, and the second processor 304 powers on and starts up, achieving synchronous power-on of both temples.

[0156] 2. Synchronous Power-Off Workflow: The user switches the physical DIP switch of the first temple 101 to the "Off" position. The DIP switch outputs a low-level trigger signal to the first NFC wireless control chip as the first control signal. After receiving the low-level trigger signal, the first NFC wireless control chip generates a power-off command, which instructs the second processor 304 to perform a power-off operation. The first NFC wireless control chip uses an encryption hardware engine to read the encryption key from the OTP security zone and encrypts the power-off command to obtain an encrypted power-off command. The first NFC wireless control chip broadcasts the encrypted power-off command externally through the NFC radio frequency module. The second NFC wireless control chip receives the encrypted power-off command, uses the encryption hardware engine to read the decryption key from the OTP security zone and decrypts the encrypted power-off command, and uses the identification information of the first temple 101 stored in the OTP security zone for validity verification. After the validity verification is successful, it outputs a power-off level to the second MOS transistor switching circuit, the second MOS transistor switching circuit is turned off, and the second power supply unit stops supplying power to the second processor 304. After broadcasting the shutdown command, the first NFC wireless control chip outputs a shutdown level to the first MOSFET switching circuit, which disconnects the first MOSFET switching circuit and physically de-energizes the first processor 204, thus achieving synchronous shutdown of both temples. After shutdown, both NFC wireless control chips remain independently powered, and the first NFC wireless control chip returns to a low-power listening state, waiting for the next power-on command. The processors in both temples are in a power-off state, resulting in low static power consumption.

[0157] In this design, the first temple 101 and the second temple 102 each use independent power supplies to power the processor, resulting in no electrical connection. The frame serves as the mechanical connection, eliminating the need for pre-installed electrical wiring and connectors. This allows for an ultra-thin, modular, and detachable design, adaptable to all types of frame shapes. The design enables simultaneous control of both sides via a single-sided DIP switch, facilitating one-handed operation and eliminating redundant steps. The control logic is implemented in hardware by the first NFC wireless control chip.

[0158] In this embodiment, the coil of the first NFC wireless control chip can be directly integrated into the flexible printed circuit (FPC) built into the temple housing, which is perfectly compatible with the slender temple with a width of only 5-12mm, without occupying the space of the battery and main functional module.

[0159] The following description uses the example of the first wireless control unit 201 as the first BLE wireless control chip, the second wireless control unit 301 as the second BLE wireless control chip, the first switching circuit 206 as the first MOSFET switching circuit, and the second switching circuit 305 as the second MOSFET switching circuit to illustrate the synchronous power-on / power-off process of the first temple 101 and the second temple 102 in smart glasses: 1. Synchronous power-on workflow: The difference between this scheme and the synchronous power-on workflow described above lies in the fact that, in this scheme, the first BLE wireless control chip detects the trigger signal of the first switch. After acquiring the high-level trigger signal, the first BLE wireless control chip generates a power-on command and encrypts it to obtain an encrypted power-on command. This power-on command is used to power on the second processor 304. Optionally, this power-on command also carries the MAC address of the second temple, which is broadcast externally by the BLE wireless control chip 3 via a BLE radio frequency transceiver.

[0160] The first BLE wireless control chip outputs a conduction level to the first MOSFET switching circuit, the first MOSFET switching circuit is turned on, and the first processor 204 is powered on and started.

[0161] The second BLE wireless control chip is in a low-power interval listening state. After receiving the encrypted power-on command, it completes the key validity verification and MAC address matching through the built-in hardware encryption engine. After the verification is successful, the second BLE wireless control chip outputs a conduction level to the second MOS transistor switching circuit. The second MOS transistor switching circuit is synchronously turned on, and the second processor 304 is powered on and started, realizing the synchronous power-on of the processors in both temples.

[0162] 2. Synchronous shutdown workflow: The difference from the synchronous power-on process described above is that in this scheme, the first BLE wireless control chip detects the low-level trigger signal on the first switch and generates a shutdown command. Optionally, the first BLE wireless control chip encrypts the shutdown command to generate an encrypted shutdown command. The shutdown command is used to trigger the power-off operation of the second processor 304 in the second temple 102. The shutdown command may also carry the MAC address of the second temple 102. Alternatively, the BLE wireless control chip 3 may broadcast the encrypted shutdown command (carrying the MAC address of the second temple 102) or broadcast a message through the BLE radio frequency transceiver. The broadcast message includes the encrypted shutdown command and the MAC address of the second temple 102.

[0163] The second BLE wireless control chip receives the encrypted shutdown command. Using its built-in hardware encryption engine, it reads the decryption key from the OTP security zone to decrypt the command, obtaining the shutdown instruction. It then uses the MAC address of the second lens mount 102 for validity verification. After successful validity verification, it outputs a shutdown level to the second MOSFET switching circuit, causing the circuit to open and the second power supply unit to power off the second processor 304.

[0164] After the first BLE wireless control chip broadcasts the shutdown command, it outputs a shutdown level to the first MOS transistor switching circuit. The first MOS transistor switching circuit is turned off, and the first power supply unit cuts off power to the first processor 204, thereby enabling the processors in both temples to be powered down synchronously.

[0165] After the processors in both temples are synchronously powered down, the two BLE wireless control chips remain independently powered. The first BLE wireless control chip returns to a low-power listening state, waiting for the next power-on command.

[0166] During after-sales repair: When replacing the temples, pairing can be completed in two ways without disassembling the casing or reserving programming contacts: Method 1: Write the original device's encryption / decryption key, peer MAC address, and / or pairing information into the BLE wireless control chip in the new temple via the authorized host computer after sales.

[0167] Method 2: By using a special DIP switch, the old and new temples are triggered to enter pairing mode, automatically completing information exchange and pairing. No professional equipment is required for operation.

[0168] It is worth noting that, in this embodiment, the circuit consisting of the first wireless control unit 201, the first power supply unit 202, the first power management unit 203 (optional), and the first switching circuit 206 (optional) in the first temple 101 can be referred to as the first power synchronization control circuit 200. The circuit consisting of the second wireless control unit 301, the second power supply unit 302, the second power management unit 303 (optional), and the second switching circuit 305 (optional) in the first temple 102 can be referred to as the second power synchronization control circuit 300.

[0169] Please see the appendix Figure 4 This application provides a power synchronization control method according to an embodiment. The method is described using the interaction of a first temple 101 and a second temple 102 as an example. The first temple 101 has, for example... Figure 2 or Figure 3 The first power supply synchronization control circuit 200 shown has the following in the second temple 102: Figure 2 or Figure 3The second power synchronization control circuit 300 shown can be executed by the first temple 101 and the second temple 102, or by devices applied in the temples, such as wireless control chips. This application embodiment does not limit this; the method includes: S401: In response to a first control signal generated by a first switch on the first temple 101, the first temple 101 sends a second control signal. Correspondingly, the second temple 102 receives the second control signal.

[0170] It is understandable that there is a communication connection between the first temple 101 and the second temple 102, which can be a Bluetooth communication connection or an NFC communication connection.

[0171] S402: In response to the first control signal, the first temple 101 controls the first power supply unit 202 in the first temple 101 to supply power to or de-energize the first processor 204.

[0172] In this embodiment, the actions of the first temple 101 controlling the first power supply unit 202 in the first temple 101 to supply or de-supply the first processor 204 and sending the second control signal can be executed synchronously. Alternatively, the actions of controlling the first power supply unit 202 in the first temple 101 to supply or de-supply the first processor 204 can be executed after sending the second control signal, so as to ensure that the actions of the first temple 101 controlling the first processor 204 to power off or on are synchronized with the actions of the second temple 102 controlling the second processor 304 to power off or on.

[0173] S403: The second temple 102 responds to the second control signal to power off or on the second processor 304 in the second temple 102.
