[0040] Figure 1 This is a flowchart illustrating a Bluetooth keyboard connection method provided in an embodiment of the present invention;

[0041] Figure 2 This is a schematic diagram of the connection device for the Bluetooth keyboard provided in an embodiment of the present invention. Detailed Implementation

[0042] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] It's worth noting that with the widespread use of electronic devices, the number of external interfaces based on wireless technology is also increasing. Bluetooth has become a common interface widely adopted by electronic devices in recent years, and the release of Bluetooth 5.0 has brought Bluetooth technology closer to maturity. The main difference between Bluetooth and Wi-Fi is that Wi-Fi can accommodate 128 user devices simultaneously per square kilometer. While peripheral input and operation devices based on Bluetooth technology, such as Bluetooth mice, keyboards, headsets, and TV remotes, are becoming increasingly widespread, Bluetooth keyboards are not as common due to cost and power consumption considerations. Traditional Bluetooth keyboard connections use a one-button start operation to enter "exploration mode" or "discoverable mode," constantly identifying the environment, checking for nearby pre-set devices, and scanning for user interaction. This hinders automatic connection and convenient operation while increasing power consumption. These Bluetooth connection methods complicate the connection process between Bluetooth keyboards and devices and increase power consumption.

[0044] In response to the above problems, refer to Figure 1 The first embodiment of the present invention provides a method for connecting a Bluetooth keyboard, including the following steps:

[0045] S11, during the Bluetooth connection process of the Bluetooth keyboard, obtain the working status and remaining battery power of the Bluetooth keyboard;

[0046] S12, based on the working state, perform a connection detection operation to obtain the connection status;

[0047] S13, Based on the link information, perform a search operation to obtain the link results;

[0048] S14, Based on the link result and the remaining power, perform a power consumption rate calculation operation to obtain the power consumption rate;

[0049] S15, a keyboard shutdown command is obtained by performing a threshold comparison and judgment operation based on the power consumption rate, and the keyboard shutdown command is sent to the Bluetooth keyboard so that the Bluetooth keyboard shuts down its Bluetooth module after receiving the keyboard shutdown command.

[0050] In step S11, during the Bluetooth connection process of the Bluetooth keyboard, the working status and remaining battery power of the Bluetooth keyboard are obtained.

[0051] In the above embodiments, during the Bluetooth keyboard connection process, it is first necessary to ensure that the Bluetooth keyboard is correctly turned on and in working condition. At this time, the keyboard's working status and remaining battery power can be retrieved in detail through a specific Bluetooth protocol. The keyboard transmits its operating status (e.g., whether it is normally turned on or turned off due to a malfunction) and remaining battery power information to the paired device via the Bluetooth protocol. This allows the user to obtain the keyboard's status information in real time and continuously monitor its battery power. The system will effectively manage based on this information, ensuring that the Bluetooth keyboard is always in working condition and has sufficient power during the Bluetooth connection process, thereby optimizing the user experience. It also calculates the remaining battery power to prevent operation interruption due to insufficient power or other problems, and on this basis, provides hardware protection for subsequent Bluetooth connections and provides an effective data foundation for subsequent calculation of power consumption rate.

[0052] It's important to note that there are two main methods for activating a Bluetooth keyboard: button activation and manual activation. For button activation, a timer is preferred. This timer is set to automatically activate the Bluetooth module after a certain time interval from when the keyboard is turned on, enabling precise control and automated operation. The timer can be set to a specific time interval to ensure the Bluetooth module activates within the predetermined time, thus optimizing the startup process. On the other hand, manual activation is preferred before or during keyboard power-on. The user manually activates the Bluetooth module during the power-on phase, directly establishing a connection with the electronic device. This method allows users to handle connection needs immediately during device startup, enabling more direct and flexible operation. Combining these two activation methods improves the Bluetooth keyboard's startup efficiency and connection stability, ensuring efficient and reliable operation in various usage scenarios.

[0053] It should also be noted that when the Bluetooth keyboard enters working mode and is turned on, it will automatically search for Bluetooth devices to identify connectable electronic devices. This search process prioritizes establishing a connection with mobile phones, followed by tablets or laptops. The electronic device should be a Bluetooth-enabled unit capable of establishing a connection via the Bluetooth protocol for data communication. This automatic search mechanism ensures that the Bluetooth keyboard can quickly and efficiently connect to the preferred device, thereby optimizing the user experience and device compatibility.

[0054] It's worth noting that to improve the convenience and operational efficiency of the Bluetooth keyboard, a dedicated power button can be designed and installed to enable one-click quick activation of the Bluetooth module. This power button can connect directly to the Bluetooth module, simplifying the Bluetooth activation process. The installation options for this button are flexible; it can be integrated into the computer's driver or related application (APP), or into mobile applications. By operating the relevant APP or driver on these platforms, users can monitor the keyboard's status in real time and promptly address Bluetooth module connection issues. This design does not require the power button to be physically installed on the Bluetooth module; instead, it operates through a software interface, providing users with a more convenient management method. This approach effectively reduces the complexity of hardware modification while enhancing the intelligence of device operation and user experience, making Bluetooth module management and troubleshooting more efficient.

[0055] It's also worth noting that the Bluetooth keyboard features user key selection and a keyboard reset mode to optimize connectivity with various electronic devices. The keyboard reset function primarily involves activating the Bluetooth module and automatically searching for nearby connectable electronic devices. During this process, users can manually select the target device, such as a mobile phone, tablet, or laptop, and establish a connection by entering the device's address code according to the Bluetooth protocol. This not only ensures effective pairing of the keyboard with the selected device but also allows users to adjust its settings via the Bluetooth keyboard. The reset process includes enabling Bluetooth, performing a search and selecting the target device, and then performing the necessary pairing and connection. Once the connection is established, users can modify the settings via the Bluetooth keyboard or manage the keyboard's input methods and configurations using a connected mobile phone, tablet, or laptop. This flexible management function allows users to customize the keyboard's operation according to specific needs, thereby improving input efficiency and ease of use. The combination of reset and manual selection functions aims to provide users with a more precise and efficient connection process, ensuring that the Bluetooth keyboard can smoothly interact with various Bluetooth-enabled devices and meet input needs in different scenarios. Through this automated and manual selection mechanism, Bluetooth keyboards not only simplify the device pairing process but also enhance the user experience and device compatibility.

[0056] In step S12, a link detection operation is performed based on the working state to obtain the link status.

[0057] In the above embodiment, the process first requires ensuring that the Bluetooth keyboard is turned on and that the keyboard and the device to be connected are within the normal working distance. Subsequently, the system will perform a series of operations to complete the connection, including scanning for nearby Bluetooth devices, initiating a connection request to the target device, receiving and parsing the target device's response, and confirming the connection status. The system will continuously monitor the status changes during the connection process, evaluating the stability and effectiveness of the connection in real time. If the connection is successful, the system will display a successful connection status and enable data exchange; if the connection fails, the system will generate a detailed error message, providing feedback on the connection failure and potentially offering further troubleshooting suggestions. The system will also record detailed logs of connection attempts for subsequent troubleshooting and performance optimization.

[0058] It should be specifically noted that the connection between the Bluetooth keyboard and electronic devices is automatic, such as between a Bluetooth watch and its related electronic devices (smartphones, tablets, laptops, smart TVs / set-top boxes, smart wearables, Bluetooth headsets). The preferred Bluetooth connection mode is Bluetooth 4.0 or higher, which includes BLE (Bluetooth Low Energy). The Bluetooth keyboard has user-selectable key settings and a keyboard reset function, automatically connecting to connectable electronic devices. The keyboard reset function of this invention refers to enabling Bluetooth, searching and selecting, manually selecting the address code of a mobile phone, tablet, or laptop, and manually establishing a connection according to the Bluetooth protocol. This allows the user to change keyboard settings via the Bluetooth keyboard or manage keyboard input using a mobile phone, tablet, or laptop.

[0059] It's also worth noting that Bluetooth primarily uses the 2.4GHz frequency band; Bluetooth 4.0 improves upon Bluetooth 3.0's radio frequency technology through software, offering faster connection speeds, a larger number of connections, and greater range. Its main feature is a connection speed increase to up to 1Mbps. Besides significantly improving performance, Bluetooth 4.0 also further reduces the size of Bluetooth devices. Previously, Bluetooth devices required approximately 16mm x 29mm; now, they only need 6mm x 4mm. Therefore, Bluetooth 4.0 products offer greater design flexibility, allowing for even smaller device shapes. Furthermore, Bluetooth 4.0 and later versions have brought significant advancements in wireless communication technology, primarily in the following aspects: First, Bluetooth 4.0 introduced Bluetooth Low Energy (BLE) technology, a communication method specifically designed for low-power devices, significantly reducing power consumption and enabling low-power devices such as wearables and smart home sensors to operate for extended periods without frequent battery replacements. Second, Bluetooth 4.0 improved data transmission, increasing packet size and transmission speed, while enhancing privacy and security, supporting stronger data encryption and privacy protection features.

[0060] Furthermore, Bluetooth 5.0 and later versions offer even greater performance improvements. Bluetooth 5.0 not only increases data transfer rates (up to 2 Mbps) but also extends communication range, allowing devices to maintain stable connections over longer distances. It also enhances broadcast capabilities, enabling devices to broadcast more information. Bluetooth versions 5.1 and 5.2 introduced positioning features such as direction finding and distance measurement, providing greater accuracy for Internet of Things (IoT) and smart home applications. These advancements have made Bluetooth technology more widely and efficiently used across multiple fields.

[0061] In step S13, a search operation is performed based on the link information to obtain the link results.

[0062] In one embodiment, after performing a search operation based on the link status and obtaining the link results, the method further includes: performing a timed detection operation based on the unlinked results to obtain a stop detection instruction, wherein the stop detection instruction includes a link success instruction and an instruction that the number of detections has exceeded a set threshold.

[0063] In one embodiment, the method further includes: when the number of detection points reaches a preset maximum number of detections, stopping the detection and starting a timer, and after a preset waiting time, restarting the detection mode.

[0064] In the above embodiments, the Bluetooth keyboard determines whether a search operation is needed based on different connection statuses. When the connection status is "connected," it directly outputs the "connected" result. When the connection status is "not connected," it performs a search operation. If an electronic device is found, a connection operation is performed, and a "connected" result is obtained. If no electronic device is found, a timed detection operation is entered. Under this operation, the timed detection operation stops when an electronic device is detected or the maximum number of detections is reached. Under the search operation, on the basis of automatic connection, further searching for electronic devices within the Bluetooth connection working range can be performed, reducing the cumbersomeness of manual Bluetooth connection operation and simplifying the Bluetooth connection process.

[0065] It should be noted that when the Bluetooth keyboard connects to electronic devices, if the number of connected devices is greater than one, it will connect to the closest electronic device or the electronic device actively selected by the user. In addition, when the number of connected devices is greater than one, it will detect the strength of the distance between each device and the Bluetooth keyboard and automatically select the closest device to connect to. If multiple devices are connected at the same time, it will prioritize the last connected device, the device for which the user has enabled shortcut keys, and the device whose distance was last detected.

[0066] It's also worth noting that after the Bluetooth keyboard starts up and completes initial testing, if a connection failure occurs, the system will automatically initiate a search mode to identify nearby connectable Bluetooth devices. This process involves scanning all Bluetooth-enabled electronic devices, including but not limited to mobile phones, tablets, and laptops. Among these connectable devices, the system prioritizes pairing with mobile phones to ensure priority connection with the most frequently used device. Mobile phones are prioritized due to their ubiquity and high usage frequency; they are typically the most frequently connected device in most users' daily operations. Furthermore, as Bluetooth-enabled units, these electronic devices can achieve efficient data communication after establishing a connection via the Bluetooth protocol. In this way, the Bluetooth keyboard ensures a smooth and stable Bluetooth connection with the user's primary device during startup and testing, providing a seamless input experience and improving user efficiency. The system's automatic connection function and priority selection mechanism aim to simplify the pairing process, reduce the complexity of manual operation, and optimize the user experience.

[0067] It should be noted that the search time can be set according to the device's broadcast frequency, and the maximum number of detections can also be adjusted according to the actual situation.

[0068] It should also be noted that when the Bluetooth keyboard enters search mode, it scans for connected electronic devices: if an electronic device is searching for the Bluetooth keyboard, the keyboard will immediately connect to it; if an unconnected electronic device is detected, a connection will be automatically established; if no connected or connectable electronic device is detected, it will periodically check until an electronic device is detected; if the maximum number of checks is reached, the detection state will end. Specifically, the detection scans for electronic devices that are already connected to the Bluetooth keyboard. When the maximum number of periodic checks is reached, the detection stops, and after a period of time, the detection mode will restart, waiting for a connection.

[0069] In step S14, based on the link result and the remaining power, a power consumption rate calculation operation is performed to obtain the power consumption rate.

[0070] In the above embodiment, after the Bluetooth keyboard successfully connects to the electronic device, the system monitors the keyboard's battery level in real time and calculates the power consumption rate by analyzing the remaining battery data. This calculation is based on real-time battery data to ensure accurate assessment of battery usage. The system provides detailed battery status feedback to the user based on the calculated power consumption rate, helping the user understand the remaining battery level. Furthermore, the system continuously monitors the user's operating patterns and usage, and automatically sends a shutdown command to interrupt the Bluetooth connection upon detecting inactivity or prolonged inactivity. This measure aims to reduce the Bluetooth keyboard's power consumption during connection, thereby optimizing energy efficiency and extending battery life. Through this intelligent management solution, the Bluetooth keyboard can significantly reduce power consumption while providing high performance, improving the overall user experience.

[0071] It should be noted that the formula for calculating the power consumption rate is as follows:

[0072] ,

[0073] in, This refers to the rate of power consumption. For the first The remaining power at each detection point For the first The remaining power at each detection point As the largest detection point, This is the first point.

[0074] For example, if the battery level of the Bluetooth keyboard is lower than a certain value (this value needs to be set manually; setting the threshold battery level according to different needs can enable personalized use of the Bluetooth keyboard), and the signal strength of the Bluetooth module on the Bluetooth keyboard drops by 20%-50%, the Bluetooth keyboard will consider the relevant reasons and decide to turn off the Bluetooth module.

[0075] In step S15, a keyboard shutdown command is obtained by performing a threshold comparison and judgment operation based on the power consumption rate, and the keyboard shutdown command is sent to the Bluetooth keyboard so that the Bluetooth keyboard shuts down its Bluetooth module after receiving the keyboard shutdown command.

[0076] In the above embodiments, the Bluetooth keyboard accurately assesses its battery status by monitoring the power consumption rate in real time and comparing it with a preset threshold power consumption rate. This process involves precise measurement of the power consumption rate and real-time analysis using algorithms to determine whether the current battery consumption exceeds a set safe range. When the power consumption rate reaches or falls below the set threshold, the system further considers the signal strength of the Bluetooth module. Measuring signal strength is crucial for determining the actual operating status and power consumption of the Bluetooth module. When the signal strength indicates low Bluetooth module efficiency, the system issues a shutdown command, requiring the Bluetooth module to stop working. At this time, the keyboard shuts down its Bluetooth module according to the received command to reduce battery consumption. After the Bluetooth module is shut down, the Bluetooth keyboard immediately enters sleep mode. Enabling this mode effectively reduces power consumption and avoids wasting battery power due to unnecessary Bluetooth activity. In sleep mode, the keyboard's Bluetooth module will no longer transmit or receive signals, greatly reducing power consumption and effectively extending battery life. Through this series of refined power management measures, the Bluetooth keyboard has achieved significant results in optimizing battery use and reducing power loss. Bluetooth keyboards not only improve battery efficiency but also effectively reduce the risk of Bluetooth functionality interruptions due to low battery. This optimization not only solves the power management problems of traditional Bluetooth keyboards but also enhances the user experience, enabling devices to maintain stable performance and a longer lifespan during extended use.

[0077] For example, when the Bluetooth module's signal strength decreases to between 20% and 50%, and the power consumption rate drops to or below a set threshold, the Bluetooth keyboard will automatically receive and execute a command to shut down the Bluetooth module. This mechanism aims to protect battery life and optimize the overall performance of the device. Furthermore, after the Bluetooth connection is disconnected and remains disconnected for ten minutes, the Bluetooth keyboard will automatically enter sleep mode. In this mode, the device will significantly reduce power consumption to maximize battery life and ensure that the device maintains a certain level of power even when not in use for extended periods. This design not only enhances the user experience but also improves the device's energy efficiency management.

[0078] It should be noted that the Bluetooth keyboard has a sleep mode (preferably, the keyboard enters sleep mode when turned off; and preferably wakes up from sleep mode when turned on) and automatic connection to connectable electronic devices. Bluetooth phones, tablets, or laptops also have sleep and wake-up states. Entering sleep mode involves inactivity for a period of time after being turned off. Ideally, a timer should be set when entering sleep mode to automatically wake the device when the timer expires. Simultaneously, the electronic device (Bluetooth phone, tablet, or laptop) remains in sleep mode and does not actively broadcast. Ideally, a wake-up broadcast should be set at regular intervals for active pairing.

[0079] It's important to note that connection failure may occur when the Bluetooth keyboard and electronic device are more than 300 meters apart. In this case, the system will issue a distance warning and suggest the user move the device to a more stable connection range. Bluetooth technology typically has an effective range of 10 to 100 meters; however, exceeding this range in actual use may cause signal attenuation, affecting the stability of the connection between devices. If the device is moved back to a stable connection range, the keyboard will automatically attempt to reconnect, or the user can manually wake the keyboard by pressing a key to re-establish the connection. When electronic devices are not used for extended periods, they may enter standby or sleep mode, at which point the Bluetooth keyboard may not detect the device. Similarly, when the distance between the keyboard and device exceeds the normal range, or when the keyboard is in an abnormal state, the keyboard may fail to detect the target device. The connection stability of Bluetooth devices depends on the effective distance between devices and their normal operating status; any non-standard conditions will affect the transmission and connection of the Bluetooth signal. Furthermore, if no connectable devices are available in the Bluetooth device list, the system will prompt the user that no devices can be connected. In this case, the user needs to wake the Bluetooth keyboard by pressing a key so that it can re-attempt to establish a connection with the electronic device. In this situation, the Bluetooth keyboard will actively scan for nearby devices and initiate a connection request when a matching device is detected. If the device list is empty, it means there are no connectable Bluetooth devices in the current environment, or the device is turned off or inactive. To resolve these issues, users need to ensure that the Bluetooth device is turned on and in pairing mode, and that the electronic device is within Bluetooth range and the keyboard is functioning properly. Regularly checking and maintaining the keyboard's battery status, Bluetooth module, and ensuring the device's Bluetooth function is working correctly will help improve the connection success rate. Through these measures, users can effectively improve the connection stability and user experience of their Bluetooth devices.

[0080] It's also worth noting that when the distance between the Bluetooth keyboard and the paired device exceeds the preset effective communication range, the Bluetooth keyboard will automatically execute a shutdown command and enter sleep mode. The core purpose of this process is to optimize battery management, reduce energy consumption, and ensure the device's longevity. In practical applications, the Bluetooth keyboard's operating state and power consumption management are highly dependent on the effective communication distance between the device and its paired device. When the distance exceeds the predetermined range, the quality and strength of the Bluetooth signal will significantly decrease, leading to communication interruption or unstable connection. To address this, the Bluetooth keyboard automatically triggers sleep mode, and when the Bluetooth keyboard initiates sleep mode upon detecting that the distance to the paired device has exceeded the communication range, it does not consider the remaining battery power. This design aims to avoid unnecessary power consumption, ensuring that the device's battery resources are effectively utilized when needed, further reducing the Bluetooth keyboard's power waste.

[0081] In summary, the Bluetooth keyboard connection method provided in this embodiment of the invention, executed by the Bluetooth keyboard, includes: during the Bluetooth keyboard's Bluetooth connection process, acquiring the keyboard's operating status and remaining battery power; performing a connection detection operation based on the operating status to obtain a connection status; performing a search operation based on the connection status to obtain a connection result; performing a power consumption rate calculation operation based on the connection result and the remaining battery power to obtain a power consumption rate; performing a threshold comparison judgment operation based on the power consumption rate to obtain a keyboard shutdown command; and sending the keyboard shutdown command to the Bluetooth keyboard so that the Bluetooth keyboard shuts down its Bluetooth module upon receiving the keyboard shutdown command.
