Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and in particular to a charging case and electronic device. Background Technology

[0002] With the development of technology, smart wearable devices have gradually appeared in people's lives, favored for their portability. However, due to their relatively small battery capacity, these devices cannot support prolonged continuous use, requiring users to charge them to avoid affecting usage. Currently, smart wearable devices on the market mainly rely on two charging methods: wired charging and wireless charging. While wired charging is stable and reliable, it is inconvenient. For example, users need to find a suitable charging cable, and due to the size limitations of smart wearable devices, wired charging often requires specific interface designs, increasing design complexity and potentially affecting the device's overall aesthetics and waterproof performance. In contrast, charging cases, as a new solution, offer users a more convenient wireless charging experience. Summary of the Invention

[0022] The main control circuit is configured to, when determining that the smart wearable device meets the charging conditions, control the first switch corresponding to the smart wearable device to be turned on and control the second switch corresponding to the smart wearable device to be turned off, so as to supply power to the smart wearable device; it is also configured to, when determining that the smart wearable device meets the external communication conditions or the internal communication conditions, control the first switch corresponding to the smart wearable device to be turned off and control the second switch corresponding to the smart wearable device to be turned on, so as to enable the smart wearable device to establish a communication connection with an external terminal or to establish a communication connection between two smart wearable devices.

[0023] In one embodiment, the main control circuit is configured to, upon receiving a communication connection trigger signal triggered by a user when the smart wearable device is detected being placed into the storage compartment, output a first communication signal to the smart wearable device via the power output terminal to trigger the establishment of a communication connection between the smart wearable devices; and / or, trigger the establishment of a communication connection between the wearable device and an external terminal.

[0024] In one embodiment, when a communication connection is established between the smart wearable devices, one type of smart wearable device reads the Bluetooth address of another type of smart wearable device and detects whether the smart wearable device corresponding to the Bluetooth address is a paired object.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0054] It should be noted that step designations such as S100 and S200 are used in this document for the purpose of more clearly and concisely describing the corresponding content, and do not constitute a substantial limitation on the order. In specific implementation, those skilled in the art may execute S200 first and then S100, etc., but these should all be within the protection scope of this application.

[0055] It should be noted that the gray areas in the accompanying drawings of this specification are for ease of identification only and do not constitute technical features in this field.

[0056] With the development of technology, smart wearable devices have gradually appeared in people's lives, favored for their portability. However, due to their relatively small battery capacity, these devices cannot support prolonged continuous use, requiring users to charge them to avoid affecting usage. Currently, smart wearable devices on the market mainly rely on two charging methods: wired charging and wireless charging. While wired charging is stable and reliable, it is inconvenient. For example, users need to find a suitable charging cable, and due to the size limitations of smart wearable devices, wired charging often requires specific interface designs, increasing design complexity and potentially affecting the device's overall aesthetics and waterproof performance. In contrast, charging cases, as a new solution, offer users a more convenient wireless charging experience.

[0057] Therefore, the present invention proposes a charging case, with reference to Figure 1 The charging box includes:

[0058] The charging case 10 has at least two sets of storage compartments, one set of storage compartments for placing one type of smart wearable device and the other set of storage compartments for placing another type of smart wearable device.

[0059] The charging component 20 has at least two power output terminals 21, each of which is electrically connected to a smart wearable device placed in one of the storage compartments to charge the smart wearable device.

[0060] In this embodiment, the charging case 10 has at least two independent storage compartments inside. The shape and size of each storage compartment can be designed according to the actual needs of the product to adapt to the shape characteristics of different types of smart wearable devices. For example, one set of storage compartments, serving as the charging case 10 for a smartwatch, can be provided with circular or square grooves to ensure the watch body is placed stably; the other set of storage compartments may be designed for smart bracelets or other small devices, with a more elongated shape suitable for placing such devices. The charging component 20 includes at least two power output terminals 21, each power output terminal 21 corresponding to a smart wearable device in one storage compartment. These power output terminals 21 are used to realize the electrical connection between the energy storage device 22 of the charging case and the smart wearable device, ensuring good electrical connection with different types of smart wearable devices. For example, one or more pairs of adjustable contact charging pins can be installed inside the storage compartment. The position of these pins can be adjusted to adapt to the charging contacts of different brands and models of smart wearable devices. When a smart wearable device is correctly placed in the charging compartment, the pogo pins accurately contact the metal contacts on the bottom or side of the device, establishing a stable electrical connection and initiating the charging process. Furthermore, the pogo pins typically have a certain spring pressure, ensuring good electrical contact even with slight movement of the wearable device within the compartment.

[0061] Specifically, different charging cases can charge different or similar types of wearable devices. Taking headphones and smart glasses as examples, the headphone case can be a small cylindrical or elliptical space, allowing for the storage of a single earphone or a pair. A magnetic module is installed inside the case; when the earphone is placed in the corresponding case, the magnet automatically attracts it into place, ensuring it is secure and aligned with the charging pogo pins for charging. The smart glasses case can be a longer space, large enough to hold a complete pair of smart glasses. The smart glasses case also has a magnetic module, ensuring the smart glasses are stably placed in the designated charging position. Furthermore, the smart glasses case can have adjustable pogo pins, adjusted according to the charging contacts on the smart glasses to ensure a good electrical connection. Using a magnetic pogo pin design, when headphones, smart glasses, or other smart wearable devices are placed in the case, the magnetism automatically aligns the device with the pogo pins, achieving a fast and reliable charging connection and initiating charging. Even if the device moves slightly during charging, good electrical contact is maintained, improving charging stability.

[0062] It should be noted that the charging case can also have a built-in intelligent control module, which mainly has the following functions: Charging management: It can identify the charging protocols of different devices and automatically adjust the output voltage and current to ensure that each device can obtain the best charging effect. Temperature monitoring: The temperature sensor built into the charging case can monitor the temperature changes during the charging process in real time. Once overheating is detected, it will immediately cut off the power to prevent device damage. Status indication: The charging case or smart glasses can use LED lights or other prompt components to inform the user of the charging status, such as charging start, charging complete, charging failure, etc. In this embodiment, the charging case can be equipped with RGB LED lights to display the battery level or charging status of itself or the smart wearable device. For example, by adjusting the brightness of red, green, and blue lights, the battery level or charging indication of the smart glasses, left earphone, and right earphone can be displayed.

[0063] In practical applications, the charging box, by setting up multiple storage compartments and corresponding power output terminals 21, can support the simultaneous charging of various types of smart wearable devices, improving device compatibility and user charging convenience.

[0064] In one embodiment, reference Figure 2 The charging box also includes:

[0065] The device detection component 30 has its detection end disposed in the receiving compartment, and is used to detect whether a smart wearable device is placed in the receiving compartment.

[0066] In this embodiment, the detection end of the device detection component 30 includes, but is not limited to, one or a combination of proximity sensors, contact detection switches, and weight sensors. When the smart wearable device approaches the storage compartment, the proximity sensor can detect the presence of the device and send a signal to the smart control module inside the charging compartment 10 to confirm that the device is ready to charge. When the smart wearable device is placed in position and contacts the pogo pins, the contact detection switch is triggered, thereby sending a signal to the smart control module indicating that the device is ready to charge. The weight sensor can be located at the bottom of the storage compartment to sense changes in the weight of the device; when an increase in weight is detected, it means that the device has been placed inside the storage compartment.

[0067] It should be noted that the charging case may also include a detection component electrically connected to the main control circuit 24, used to detect the state of the charging case to enable a lid-open detection function. The detection component includes, but is not limited to, mechanical switches, magnets, magnetic sensitive elements, and optical sensors. For example, a small magnet can be installed on the charging case lid, and a Hall sensor or reed switch can be installed inside the case. When the lid is closed, the magnet approaches the magnetic sensitive element, triggering a signal; when the lid is opened, the magnet moves away from the magnetic sensitive element, and the signal disappears. Thus, the main control circuit 24 can determine whether the charging case lid is open based on the second detection signal output by the detection component. When the lid is open, the charging case then controls the device detection component 30 to detect whether smart glasses or earphones have been placed inside.

[0068] In practical applications, when the user opens the charging case lid, the main control circuit 24 of the charging case automatically wakes up the corresponding functional modules (such as the device detection component 30) and enters the working state. When the user closes the lid, the charging case automatically enters a sleep state to save power. In this way, power consumption of the charging case is reduced, and the battery power of the charging case is saved.

[0069] Optionally, refer to Figure 3 The charging box also includes:

[0070] Main controller 40, which is electrically connected to the device detection component 30;

[0071] The device detection component 30 is used to detect whether the smart wearable device is placed into the receiving compartment and output a corresponding detection signal to the main controller 40;

[0072] The main controller 40 is used to detect whether the two types of smart wearable devices meet the charging conditions, the external communication conditions, and the internal communication conditions when the detection signal determines that both types of smart wearable devices are placed in the receiving compartment.

[0073] In this embodiment, the main controller 40 can be implemented using MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), PLC, SOC (System On Chip), etc.

[0074] Optionally, the battery management system (BMS) built into the smart wearable device can detect the remaining battery power and communicate with the charging case via corresponding communication protocols (such as Bluetooth, NFC, etc.). When the smart wearable device is placed in the corresponding compartment of the charging case 10 and a connection is established via pogo pins, the main controller 40 will query the device's battery status via the communication protocol. If the device's remaining power is lower than a preset power threshold (e.g., 20%), the device is considered to need charging; otherwise, the device is considered not to need charging for the time being. Specifically, when the user places the smart wearable device into the charging case 10, the device detection component 30 detects that the device is in place and outputs a detection signal to the main controller 40 to query the device's battery status via the communication protocol. It then performs a power level check to determine whether the charging conditions are met. If the charging conditions are met, the main controller 40 issues a command to start the charging process.

[0075] Taking headphones and smart glasses as examples, when the device detection component 30 detects that the headphones and smart glasses are placed in the charging case 10 at the same time, the built-in battery management systems of the two smart wearable devices can send their real-time power status through a communication protocol, or the smart control module inside the charging case can actively send a communication signal to detect the remaining power of the two smart wearable devices. Thus, the main controller 40 can obtain the power levels of the headphones and smart glasses and execute the corresponding charging strategy. Optionally, the charging case can prioritize charging the smart wearable device with the lower power level, and then charge both smart wearable devices simultaneously when their power levels are equal. Optionally, the charging case can allocate power based on the power level of its own energy storage device 22. For example, if the power level of the energy storage device 22 exceeds a first preset threshold and is sufficient to charge both smart wearable devices, it can charge both headphones and smart glasses simultaneously; if the power level of the energy storage device 22 is less than or equal to the first preset threshold, it will prioritize charging the device with the lower power level based on the current remaining power levels of the headphones and smart glasses. Optionally, the charging case may also have corresponding control buttons for different compartments, or the charging case may contain a communication module to establish a communication connection with an external terminal. In this way, users can set charging priorities via the control buttons on the charging case or via an external terminal (such as a smartphone). When the earphones and smart glasses are placed in the charging case 10 simultaneously, the main controller 40 will charge both types of smart devices first according to the set priority. For example, if the user only needs to use the smart glasses and does not need to use the audio playback function, the smart glasses can be charged first. After the smart glasses are fully charged or reach a preset battery level, the main controller 40 allocates equal power output to both power output terminals 21, causing the earphones and smart glasses to start charging simultaneously.

[0076] It should be noted that the charging case needs to know whether the smart wearable devices are in a working state. If communication activities are taking place between smart wearable devices or between smart wearable devices and external terminals (such as answering calls, playing music, synchronizing data, etc.), the charging case should avoid interfering with these activities as much as possible. Furthermore, in some cases, if the devices are communicating, it may not be suitable to start charging immediately to avoid affecting communication quality or data transmission. Therefore, in this embodiment, when the main controller 40 determines that a smart wearable device has been placed in the storage compartment based on the detection signal output by the device detection component 30, it can detect whether the smart glasses and headphones have established a communication connection with an external terminal. For example, after the smart wearable device is placed in the storage compartment, a communication connection will be established between the smart wearable device and the charging case. In this case, the main controller 40 can output a corresponding control signal to the smart wearable device so that the communication module inside the smart wearable device can detect the current communication connection status. For example, the connection status can be detected via Bluetooth or Wi-Fi modules. For instance, the main controller 40 in the charging case can send a query command to the smart glasses or headphones to inquire whether a communication connection has been established with an external terminal or another type of wearable device. After receiving a query command, the smart glasses or earphones will report their current communication status (connected or not). The charging case can then determine whether the smart glasses or earphones require external or internal communication based on the feedback signal and take appropriate measures accordingly.

[0077] To further enhance the system's functionality, users can also set the priority of external and internal needs through a mobile application or a button on the charging case. The charging case can also dynamically adjust the charging strategy based on the actual usage of the device. For example, it can start charging immediately when it detects that the device is about to run out of power, even if there are external or internal communication needs, so as not to affect normal use.

[0078] The above settings ensure charging management without affecting device communication functions, thereby improving user experience and device efficiency. The charging case itself does not need to maintain a constant communication connection with smart glasses or earphones; it only needs to establish a brief connection when needed to obtain communication status information.

[0079] In another embodiment of the invention, reference Figure 4 The charging component 20 includes:

[0080] Energy storage device 22 is used to store electrical energy;

[0081] Charging circuit 23, the input terminal of which is connected to energy storage device 22;

[0082] Main control circuit 24, which is electrically connected to the controlled end of charging circuit 23;

[0083] At least two sets of switching devices 25, the controlled terminal of the switching device 25 is electrically connected to the main control circuit 24, and each of the switching devices 25 is connected in series between the output terminal of the charging circuit 23 and a power output terminal 21;

[0084] The main control circuit 24 is used to control the switching device 25 to turn on / off, so as to control the electrical connection between the charging circuit 23 and the corresponding power output terminal 21 to be on / off.

[0085] In this embodiment, the energy storage device 22 can be implemented using lithium-ion batteries, solar cells, supercapacitors, etc. The charging circuit 23 can be implemented using voltage conversion circuit 2 (such as any one or more of boost, buck, and buck-boost circuits). The main control circuit 24 can be implemented using MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), PLC, SOC (System-on-Chip), etc. The switching device 25 can be implemented using contactors, relays, or other switching devices, or MOSFETs, IGBTs, transistors, etc.

[0086] Among them, reference Figure 5 Each group of the switching devices 25 includes:

[0087] The first switch has a first end electrically connected to the output end of the charging circuit 23, a second end electrically connected to the power output end 21, and a controlled end electrically connected to the main control circuit 24.

[0088] The second switch has its first end electrically connected to the main control circuit 24 and its second end electrically connected to the power output terminal 21.

[0089] The main control circuit 24 is used to control the first switch corresponding to the smart wearable device to be turned on and the second switch corresponding to the smart wearable device to be turned off when it is determined that the smart wearable device meets the charging conditions, so as to supply power to the smart wearable device; it is also used to control the first switch corresponding to the smart wearable device to be turned off and the second switch corresponding to the smart wearable device to be turned on when it is determined that the smart wearable device meets the external communication conditions or the internal communication conditions, so as to enable the smart wearable device to establish a communication connection with an external terminal or to establish a communication connection between two smart wearable devices.

[0090] The main control circuit 24 is used to control the second switch corresponding to the smart wearable device to be turned on when the smart wearable device is placed into the storage compartment, so as to send a first communication signal to the smart wearable device through the second switch and the power output terminal 21.

[0091] In this embodiment, the charging box includes two sets of switching devices 25, with the first and second switches using MOSFETs as an example. Assume the first set of switching devices 25 is used to connect / disconnect the output of the charging circuit 23 to the first power output, and the second set of switching devices 25 is used to connect / disconnect the output of the charging circuit 23 to the second power output. The first power output is used to connect to the power supply of the smart glasses, and the second power output is used to connect to the power supply of the earphones. Based on the above embodiment, when the main control circuit 24 determines that the earphones and / or smart glasses meet the charging conditions, it controls the first switch corresponding to the smart wearable device to turn on and the second switch corresponding to the smart wearable device to turn off, thus charging the smart wearable device. When it determines that the earphones and / or smart glasses meet the external or internal communication conditions, it controls the first switch corresponding to the smart wearable device to turn off and the second switch corresponding to the smart wearable device to turn on, enabling the wearable device to perform external or internal communication connections. If the earphones and / or smart glasses need charging, it controls the corresponding first switch to turn on and the second switch to turn off, allowing charging. If the earphones and / or smart glasses are communicating, the corresponding first switch is turned off and the second switch is turned on, allowing communication until it is complete. Then, the second switch is turned off and the first switch is turned on to switch to charging mode. In practical applications, when the smart wearable device is placed in the charging case 10, the first switch is off and the second switch is on, enabling the main control circuit 24 of the charging case to establish communication with the earphones or smart glasses and send communication signals. Furthermore, if the smart wearable device does not need charging or communication, both the first and second switches are turned off.

[0092] Specifically, when both the earphones and smart glasses are placed in the charging case, the main control circuit 24 of the charging case determines the presence of the smart wearable device based on the detection signal output by the device detection component 30. At this time, in order to establish a communication connection with the smart wearable device and confirm its status, the main control circuit 24 controls all first switches to open and the second switches to close. If the battery level of the earphones and smart glasses is detected to be below a preset threshold (e.g., 20%), the main control circuit 24 controls the corresponding first switch to close, causing the device to enter a charging state. If the earphones and smart glasses are communicating (e.g., the earphones are playing music and the smart glasses are displaying a notification), the main control circuit 24 controls the corresponding first switch to open and keeps the second switch closed. If, after the user places the earphones and smart glasses in the charging case, the main control circuit 24 determines that the earphones and smart glasses have no internal or external communication needs, it will execute the corresponding charging strategy based on the battery levels of the earphones and smart glasses. For example, if the earphone battery level is detected to be 15% and the smart glasses battery level to be 10%. The system controls the first switch of the first set of switching devices 25 to be on and the second switch to be off, and also controls the first switch of the second set of switching devices 25 to be off and the second switch to be off. When the headphones and smart glasses have equal battery levels, the system simultaneously controls the first switches of each set of switching devices 25 to be on, so that the headphones and smart glasses can be charged simultaneously. It should be noted that the charging strategy can be set by the R&D personnel or the user through the charging case or an external terminal to meet the user's actual needs.

[0093] Taking TWS (True Wireless Stereo) earbuds as an example, the case includes two independent earbuds: a left earbud (left earbud) and a right earbud (right earbud). The charging case includes at least three power output terminals 21, each including at least one set of switching devices 25. Assume the first power output terminal is used to connect to the smart glasses, including a first switch Q11 and a second switch Q12; the second power output terminal is used to connect to the left earbud, including a first switch Q21 and a second switch Q22; and the third power output terminal is used to connect to the right earbud, including a first switch Q31 and a second switch Q32. Each power output terminal 21 may include at least two contacts, such as a positive Pogopin and a positive Pogopin. When the smart glasses are inserted into the charging case, the contacts corresponding to the first power output terminal contact and connect electrically with the contacts on the smart glasses to transmit charging or communication signals. When the left earbud is inserted into the charging case, the contacts corresponding to the second power output terminal contact and connect electrically with the contacts on the left earbud to transmit power or communication signals. When the right earbud is inserted into the charging case, the contact corresponding to the third power output terminal makes contact with and electrically connects to the contact on the right earbud to transmit power or communication signals. Under the initial condition of the smart wearable device being placed in the charging case, the main control circuit 24 controls all first switches to open and the second switches to close. If the earbuds and smart glasses are communicating (e.g., the earbuds are playing music and the smart glasses are displaying a notification), or the smart glasses are communicating with an external terminal, the main control circuit 24 controls the corresponding first switch Q21 to open and keeps the second switch Q22 on. Assuming that after the user places the left earbud, right earbud, and smart glasses into the charging case, the main control circuit 24 determines that the earbuds and smart glasses have no internal or external communication needs, it will execute the corresponding charging strategy based on the battery levels of the earbuds and smart glasses. For example, assuming the battery levels of the left earbud and smart glasses are detected to be below a preset threshold (e.g., 20%), and the right earbud is above the preset threshold, for example, when the battery levels of the left earbud are detected to be 15%, the right earbud 35%, and the smart glasses 10%. If the user does not input specific usage requirements, the main control circuit 24 can charge the device with the lower battery level first. Specifically, the main control circuit 24 will control the corresponding first switch Q21 to turn on, allowing the smart glasses to enter charging mode first. When the smart glasses' battery level reaches 15%, it controls the first switch Q21 to turn on and the second switch Q22 to turn off. At this time, the first switch Q11 remains on, and the second switch Q12 remains off, meaning the charging case simultaneously charges both the smart glasses and the left earphone.If the left earbud reaches the preset threshold of 20% first, the first switch Q21 and the second switch Q22 will be turned off, temporarily stopping charging the left earbud. Once the smart glasses' battery reaches 20%, the first switch Q31 will be turned on, the second switch Q32 will be turned off, and the first switch Q21 will be turned on again, while the first switch Q11 will remain on, allowing the charging case to charge the left earbud, right earbud, and smart glasses simultaneously. During charging, the main control circuit 24 of the charging case can adjust the output parameters of the voltage conversion circuit 2 to output different voltage levels to the left earbud, right earbud, and smart glasses, ensuring that the battery percentages of the left earbud, right earbud, and smart glasses increase synchronously. This achieves balanced battery levels for the left earbud, right earbud, and smart glasses. By ensuring that each smart wearable device has the same battery level, damage caused by overcharging when multiple smart wearable devices are placed in the charging case simultaneously can be avoided, protecting the smart wearable devices. Furthermore, it ensures that users are not affected by differences in battery levels when switching between different smart wearable devices, improving the user experience.

[0094] Understandably, the number of Pogo Pins for direct connection between the charging case and smart glasses or TWS earphones can be set according to actual needs. A flexible choice can be made between a 2-pin or multi-pin connection scheme. When using a 2-pin connection scheme, communication and power functions can be multiplexed through carrier communication. That is, the configuration of the first and second switches in each group of switching devices 25 allows the power output terminal 21 to transmit both charging and communication signals. This reduces the number of Pogo Pins, saves space, and simplifies the design. To a certain extent, this reduces hardware costs and simplifies the manufacturing process.

[0095] With the above settings, the charging case can determine when to start charging based on the actual power needs of the smart glasses and earphones, thereby avoiding unnecessary power waste and dynamically adjusting the charging strategy. For example, when the device's battery level is detected to be below a preset threshold, charging will start immediately to ensure the device is always available. When the smart glasses or earphones are engaged in important communication activities (such as making calls or playing audio), the charging case will prioritize ensuring the continuity of communication and temporarily stop charging. Users can also set different charging strategies and priorities through the charging case or external terminals (such as smartphone apps) to adapt to different usage scenarios.

[0096] In one embodiment, the main control circuit 24 is configured to output a first communication signal to the power output terminal 21 when the smart wearable device is placed into the storage compartment; and to receive a first feedback signal from the smart wearable device after receiving the first communication signal, so as to determine whether the smart wearable device has communication requirements.

[0097] Specifically, when the smart glasses and earphones are placed in the charging case's compartment, the device detection component 30 (such as a contact detection switch) detects the presence of the devices and sends a detection signal to the main control circuit 24. Based on the detection signal, the main control circuit 24 determines that the smart wearable device is in the compartment. The main control circuit 24 then controls the corresponding first switch to open and the second switch to close, allowing the power output terminal 21 to send a first communication signal to the smart wearable device. Upon receiving the first communication signal, the smart glasses and earphones send a first feedback signal back to the charging case, indicating the current communication status, so that the main control circuit 24 can determine whether the corresponding smart wearable device has communication requirements based on the received first feedback signal. Based on the first feedback signal, the main control circuit 24 controls the switching state of the corresponding switching device 25 to meet the device's requirements.

[0098] In this embodiment, when the main control circuit 24 determines that the smart wearable device has communication needs based on the first feedback signal, it controls the corresponding second switch to be turned on and the corresponding first switch to be turned off until the smart wearable device completes communication; it is also used to control the corresponding first switch to be turned on and the corresponding second switch to be turned off when the smart wearable device does not have communication needs based on the first feedback signal, so as to charge the smart wearable device.

[0099] For example, when only the smart glasses are placed in the storage compartment, the second switch of the first set of switching devices 25 is in the on state, so as to send a first communication signal to the smart wearable device through the second switch and the power output terminal 21. That is, the main control circuit 24 outputs the first communication signal to the power output terminal 21 electrically connected to the smart glasses, and detects the signal change on the power output terminal 21 and receives the first feedback signal. If no first feedback signal is received or the first feedback signal indicates that the smart glasses have communication needs, the second switch is kept on and the first switch is off. If the first feedback signal is received or the first feedback signal indicates that the smart glasses do not have communication needs, the main control circuit 24 can execute a charging strategy according to the power status of the smart glasses. If the smart glasses need to be charged, the first switch of the first set of switching devices 25 is closed and the second switch is opened to charge the smart glasses. If the smart glasses do not need to be charged or communicate, both the first switch and the second switch are opened.

[0100] It is understood that the main control circuit 24 is used to output a first communication signal to the power output terminal 21 at preset time intervals when the smart wearable device is placed in the receiving compartment. That is, when the main control circuit 24 determines that the smart wearable device is in the corresponding receiving compartment, it will control the second switch in the corresponding switching device 25 to close at preset time intervals (e.g., every 5 seconds), allowing the power output terminal 21 to send the first communication signal to the smart wearable device. The preset time interval is set in advance by the developers. Sending communication signals at preset time intervals can reduce unnecessary communication, thereby reducing power consumption and saving electricity. Because smart wearable devices typically rely on limited battery capacity, frequent communication may consume a lot of power. By sending communication signals at regular intervals, it can be ensured that the device does not communicate when unnecessary, thereby saving energy and extending the battery life of the charging case and the wearable device. Furthermore, by sending communication signals at regular intervals, it can effectively reduce signal conflicts or interference that may occur when multiple devices communicate simultaneously, improving the reliability and stability of communication.

[0101] In one embodiment of the present invention, the main control circuit 24 is configured to, upon receiving a communication connection trigger signal triggered by a user when the smart wearable device is detected to be placed in the storage compartment, output a first communication signal to the smart wearable device via the power output terminal 21 to trigger the establishment of a communication connection between the smart wearable devices; and / or, trigger the establishment of a communication connection between the wearable device and an external terminal.

[0102] In this embodiment, the charging case may be equipped with a trigger button. When the user presses the trigger button, the main control circuit 24 receives the communication connection trigger signal output by the user pressing the trigger button and outputs a first communication signal to the smart wearable device. For example, when both the smart glasses and the earphones are placed in the charging case, the main control circuit 24 outputs the first communication signal to the smart glasses and the earphones respectively to trigger the establishment of a communication connection between the smart glasses and the earphones, and / or, the establishment of a communication connection between the smart glasses and an external terminal, and the establishment of a communication connection between the earphones and an external terminal. In practical applications, different trigger buttons can be set on the charging case, corresponding to communication between smart wearable devices or between smart wearable devices and external terminals, so that the user can achieve communication connection between different devices by pressing the corresponding trigger button.

[0103] Optionally, when triggering the establishment of a communication connection between the smart wearable devices, one type of smart wearable device reads the Bluetooth address of another type of smart wearable device and detects whether the smart wearable device corresponding to the Bluetooth address is a paired object. If the smart wearable device corresponding to the Bluetooth address is a paired object, pairing is performed; if the smart wearable device corresponding to the Bluetooth address is not a paired object, the Bluetooth address is written into the pairing list for pairing. Specifically, taking the pairing connection between smart glasses and headphones as an example, when the user presses the trigger button on the charging case (corresponding to the button for establishing a communication connection between smart wearable devices), the smart glasses act as the master controller. Since the smart glasses and headphones are electrically connected to the charging case respectively, they can communicate with each other via communication lines such as UART. That is, the smart glasses read the Bluetooth address of the headphones and determine whether the Bluetooth address of the headphones has been written into the pairing connection based on the read Bluetooth address, i.e., detect whether the headphones and smart glasses have been paired. If pairing has been completed, the user can directly select the Bluetooth address corresponding to the headphones in the pairing list of the smart glasses to pair and connect. If pairing is not completed, the main control circuit 24 of the smart glasses needs to write the Bluetooth address of the earphone into the pairing list and establish a pairing connection. This enables Bluetooth communication between the earphone and the smart glasses.

[0104] Optionally, when the smart wearable device is triggered to establish a communication connection with an external terminal, the smart wearable device enters a pairing mode to pair and connect with the external terminal. After the smart wearable device and the external terminal are paired and connected, the smart wearable device receives network information input by the user to establish a communication connection between the smart wearable device and the external terminal. Specifically, assuming the smart glasses are communicating with an external terminal (mobile phone), the user can trigger the trigger button on the smart glasses to put the smart glasses into Bluetooth pairing mode and connect with the mobile phone via Bluetooth. After the user connects the smart glasses via Bluetooth through the mobile phone, they can perform network pairing and connection through the mobile phone APP, outputting the corresponding network information to the smart glasses. That is, after receiving the network information input by the user, such as the Wi-Fi name and password entered by the user, the smart glasses connect to Wi-Fi, thus realizing the network pairing and connection between the smart glasses and the external terminal.

[0105] Optionally, the main control circuit 24, upon receiving a communication connection trigger signal triggered by the user when the smart wearable device is placed in the storage compartment, reads the Bluetooth address of one type of smart wearable device, outputs it to the other type of smart wearable device, and stores it to establish a communication connection between the smart wearable devices. Specifically, taking headphones and smart glasses as examples, when the main control circuit 24 of the charging case receives a communication connection trigger signal from the user triggering the corresponding trigger button, it reads the Bluetooth address of the headphones and transmits it to the smart glasses. This allows the main control circuit 24 of the smart glasses to detect whether the Bluetooth address of the headphones has been written into the pairing connection list, i.e., whether the headphones and smart glasses have been paired. If pairing is complete, the user can directly select the Bluetooth address of the headphones from the pairing list on the smart glasses to pair and connect. If pairing is not complete, the main control circuit 24 of the smart glasses needs to write the Bluetooth address of the headphones into the pairing list and perform the pairing connection. In this way, a Bluetooth communication connection between the headphones and smart glasses can be established.

[0106] Optionally, the main control circuit 24 is used to send a communication connection trigger signal to the smart wearable device when it detects that the smart wearable device has been placed into the storage compartment, causing the smart wearable device to enter pairing mode for pairing and connection with an external terminal. After the smart wearable device is paired and connected with the external terminal, it receives network information input by the user to establish a communication connection between the smart wearable device and the external terminal. Specifically, assuming the smart glasses are communicating with an external terminal (mobile phone), the user can trigger the corresponding trigger button on the charging case, causing the main control circuit 24 of the charging case to output a control connection signal to the smart glasses, causing the smart glasses to enter Bluetooth pairing mode and connect to the mobile phone via Bluetooth. When the user connects the Bluetooth module of the smart glasses through the mobile phone, they can perform network pairing and connection through the mobile phone APP, outputting the corresponding network information to the smart glasses. That is, after receiving the network information input by the user, such as the Wi-Fi name and password entered by the user, the smart glasses perform Wi-Fi connection, thus realizing the network pairing and connection between the smart glasses and the external terminal.

[0107] In practical applications, users only need simple operations (such as pressing the corresponding trigger button) to trigger automatic pairing and connection between smart wearable devices, or to establish network communication connections (such as Wi-Fi connections) between smart wearable devices and external terminals, improving pairing efficiency and enhancing user experience. Furthermore, the charging case enables rapid pairing and network connections between smart wearable devices and between smart wearable devices and external terminals, promoting collaborative work among multiple devices.

[0108] In one embodiment, reference Figure 6The charging circuit 23 further includes one or more combinations of the following circuits:

[0109] The charging management circuit 1 is used to detect the voltage and / or current of the energy storage device 22, and output the corresponding voltage detection signal and / or current detection signal to the main control circuit 24.

[0110] Voltage conversion circuit 2 is used to convert the voltage of the energy storage device 22 and output it to the power output terminal 21;

[0111] The main control circuit 24 is used to control the operating state of the voltage conversion circuit 2 according to the received voltage detection signal and / or current detection signal;

[0112] Charging port 3 is used to connect to the power supply voltage;

[0113] The overvoltage protection circuit 4 is used to detect the power supply voltage of the charging interface 3 and output the corresponding first voltage signal to the charging management circuit 1.

[0114] Overcurrent protection circuit 5, the overcurrent protection circuit 5 is used to detect the current of the charging interface 3 and output a corresponding first current signal to the charging management circuit 1;

[0115] The charging management circuit 1 is used to output a corresponding stop charging signal to the main control circuit 24 when it is determined from the first voltage signal that the voltage of the charging interface 3 exceeds a preset voltage threshold, and / or when it is determined from the first current signal that the current of the charging interface 3 exceeds a preset current threshold.

[0116] In this embodiment, the charging management circuit 1 can be implemented using a dedicated charging management chip. Alternatively, it can be implemented using a microcontroller with an ADC (analog-to-digital converter) and a combination of peripheral circuits to detect voltage and current. The peripheral circuits may include switching transistors such as MOSFETs (field-effect transistors) and triodes to control the on / off state of the charging path, as well as necessary resistors and capacitors for signal conditioning. The voltage conversion circuit 2 can be implemented using one or more of the boost circuit, buck circuit, and buck-boost circuit described in the above embodiments, to convert the voltage of the energy storage device 22 and output it to the power output terminal 21 to meet the different power needs of the smart wearable device. The charging interface 3 can be implemented using interfaces such as USB-C, Lightning, and Type-C. The charging interface 3 can connect to various power sources, such as AC power, which can be converted to DC power through an adapter, or vehicle power, portable power (such as a power bank), solar charging panel, etc., to charge the battery (energy storage device 22) inside the charging box. The charging overvoltage protection circuit 4 can be implemented using a comparator circuit, Zener diode, etc. The overcurrent protection circuit 5 can be implemented using a Hall sensor, shunt resistor, thermistor, etc.

[0117] Specifically, the charging management chip monitors the status of the energy storage device 22, including voltage and current, and sends the corresponding voltage detection signal and / or current detection signal to the main control circuit 24. It also receives the first voltage signal from the overvoltage protection circuit 4 and the first current signal from the overcurrent protection circuit 5, and takes appropriate actions based on these signals. The voltage conversion circuit 2 converts the voltage provided by the energy storage device 22 into an appropriate voltage level to provide suitable power output for the smart wearable device, ensuring safe charging. The overvoltage protection circuit 4 prevents excessive voltage at the charging interface 3, which could damage the energy storage device 22. When the charging management chip determines that the charging voltage exceeds a preset voltage threshold based on the first voltage signal output by the overvoltage protection circuit 4, it outputs a stop charging signal to the main control circuit 24, causing the main control circuit 24 to cut off the power to the charging case. At least one power switch is connected in series between the charging interface 3 and the energy storage device 22. When the charging voltage exceeds the preset voltage threshold, the main control circuit 24 controls the power switch to open, stopping the external power supply from charging the energy storage device 22 of the charging case. Similarly, the overcurrent protection circuit 5 is used to prevent excessive charging current from the energy storage device 22. During charging, the overcurrent protection circuit 5 continuously monitors the charging current of the charging interface 3. When the charging management chip determines that the charging current exceeds the preset current threshold based on the first current signal output by the overcurrent protection circuit 5, it outputs a stop charging signal to the main control circuit 24 to cut off the power output of the charging box. This is similar to controlling the power switch to turn off. In other words, when overvoltage or overcurrent occurs, the charging management circuit 1 will send a stop charging signal to the main control circuit 24, thereby interrupting the charging process and preventing damage to the energy storage device 22.

[0118] With the above settings, the charging management circuit 1 can monitor the charging voltage and charging current of the energy storage device 22 in real time, the overvoltage protection circuit 4 can detect the power supply voltage of the charging interface 3, and the overcurrent protection circuit 5 can detect the charging current of the charging interface 3, so as to prevent the energy storage device 22 from overheating or being damaged due to excessive current or voltage, and ensure the safety of the charging process.
