Description

Technical Field

[0001] This invention relates to the field of mobile charging equipment technology, and in particular to a portable power supply device with wireless interactive control function. Background Technology

[0002] A mobile charging device is a portable electronic device with a built-in rechargeable battery module that can provide power to mobile phones, tablets and other terminal devices when traveling. Its core function is to output power to terminal devices through wired or wireless means. It is widely used in daily commuting, outdoor work and emergency power supply scenarios.

[0003] With the development of IoT technology, some mobile charging devices have begun to integrate wireless interactive control functions. By using built-in Bluetooth modules or infrared transmitters, they can establish communication connections with smart home devices, power tools, and other external mechanical products. This allows users to send control commands to external mechanical products through physical buttons or touch interfaces on the mobile charging device while charging their own devices, thus integrating charging and remote control functions.

[0004] However, the following problems still exist in the existing technology: I. In existing mobile charging devices with integrated wireless control functions, the charging channel and the control channel share the same battery resources, but there is a lack of dynamic coordination mechanism for the power consumption of the two. When the terminal device is in a high-power charging state, the control channel frequently disconnects due to insufficient energy, resulting in lost commands or delayed responses when the user operates external mechanical products.

[0005] Second, existing mobile charging devices adjust charging power solely based on the remaining battery power of the terminal device when generating charging control strategies, without taking into account the operating status of external mechanical products. This results in the terminal device charging at full power even under high load, exacerbating the overheating problem of the terminal device.

[0006] Third, existing mobile charging devices only support a single communication protocol when wirelessly controlling external mechanical products. When the Bluetooth signal deteriorates due to increased distance or physical obstruction, it cannot automatically switch to other communication methods, resulting in the interruption of the control link. Furthermore, there is a lack of device type-based adaptation and mapping mechanism between the control input and control commands, so users cannot directly control different types of external mechanical products through the physical controls on the power bank itself.

[0007] Therefore, to solve the above problems, a portable power supply device with wireless interactive control function is proposed. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides the following technical solution: A system for a portable power supply device with wireless interactive control functionality includes: The battery module, located within the power bank, stores electrical energy and provides a shared energy source for external charging and wireless interactive control.

[0009] The charge / discharge management module, which is electrically connected to the battery module, is configured to adjust the charging power to the terminal device according to the charging control signal.

[0010] The multi-protocol communication module, integrated inside the power bank, includes a Bluetooth Low Energy communication unit and an infrared transmitter unit. It is configured to establish a wireless connection with external mechanical products, send control commands, and receive status feedback data returned by them.

[0011] The device interaction engine is electrically connected to the multi-protocol communication module, the charge / discharge management module, and the physical interaction interface of the device. It is configured to: fuse status feedback data with the usage status data of the terminal device to generate scene tags, output the scene tags as charging control signals to the charge / discharge management module, and translate the control events generated by the physical interaction interface of the device into control commands and output them to the multi-protocol communication module.

[0012] The physical interface of the device is set on the outer surface of the power bank and is electrically connected to the device interaction engine. It is configured to receive user control input and generate control events.

[0013] The energy budget arbitrator is electrically connected to the battery module, the charge / discharge management module, and the device interaction engine, respectively. It is configured to calculate the available control budget of the control channel based on the remaining energy of the battery module and the real-time power demand of the charge / discharge management module. When the available control budget is lower than a preset threshold, it sends a frequency reduction command to the device interaction engine.

[0014] As an improvement to the above technical solution: The device interaction engine is configured to perform multi-protocol adaptive switching operations: when the connection signal strength between the Bluetooth Low Energy communication unit and the external mechanical product is lower than a preset threshold, it automatically switches to the infrared transmitting unit to send control commands; when it is detected that the external mechanical product supports the near-field communication protocol and the distance is less than a preset safe distance, it prioritizes establishing an encrypted connection through the near-field communication unit.

[0015] As an improvement to the above technical solution: Identify the equipment type and current working mode of the external mechanical product, and generate an equipment status identifier.

[0016] Obtain the remaining battery power and the type of application currently running on the terminal device, and generate a terminal status identifier.

[0017] The device status identifier and the terminal status identifier are combined and encoded to generate the scene label.

[0018] As an improvement to the above technical solution: When the scene label indicates that the terminal device is in a high-load application operation state and the external mechanical product is in a working state, the charging power will be reduced to a first power threshold.

[0019] When the scene label indicates that the terminal device is in standby mode and the external mechanical product is in standby mode, the charging power is reduced to a second power threshold, which is less than the first power threshold.

[0020] As an improvement to the above technical solution: When the available control budget is higher than the first budget threshold, the device interaction engine is controlled to run in full-speed mode, and the multi-protocol communication module maintains full-frequency communication.

[0021] When the available control budget is lower than the first budget threshold but higher than the second budget threshold, the device interaction engine is controlled to operate in a reduced frequency mode, the communication frequency of the multi-protocol communication module is reduced to the first reduced frequency threshold, and the status polling of non-critical external mechanical products is suspended.

[0022] When the available control budget is lower than the second budget threshold, the control channel of the device interaction engine is turned off, and only the charging function of the charge and discharge management module is retained.

[0023] As an improvement to the above technical solution: Based on the equipment type identifier of the currently connected external mechanical product, match the corresponding mapping relationship from the pre-stored protocol adapter library.

[0024] The control inputs of the physical interaction interface of the main body are translated into control commands for the corresponding external mechanical products according to the mapping relationship.

[0025] The physical interface of the device includes a knob control and a group of function buttons. The rotation operation of the knob control is mapped to the continuous adjustment of the parameters of the external mechanical product, and the pressing operation of the function button group is mapped to the mode switching or on / off control of the external mechanical product.

[0026] As an improvement to the above technical solution: The security control module is configured to perform the following security verification operations before the device interaction engine outputs the control command to the multi-protocol communication module: determine whether the control command belongs to a pre-stored allowed operation whitelist, determine whether the state of the external mechanical product after executing the control command exceeds the preset security boundary conditions, and only forward the control command to the multi-protocol communication module when the control command passes the above two verifications.

[0027] As an improvement to the above technical solution: A portable power supply device with wireless interactive control function, using the system as described in any one of claims 1-7, the device comprising: The power bank serves as the outer casing for the system.

[0028] A display screen is located on one side of the upper surface of the power bank and is used to display power information and status parameters for wireless interactive control.

[0029] A button, located next to the display screen, is used to trigger system function switching or confirmation commands.

[0030] A magnetic charging pad is disposed on the other side of the upper surface of the power bank, and is used to make electrical connections and fix the position with external terminal devices by magnetic attraction.

[0031] The data cable is connected to one side of the power bank through a storage structure, and its end is equipped with a charging connector for plugging into an external terminal device for power supply or data transmission.

[0032] A charging interface is located on the end face of the power bank and is used to replenish the battery module with electrical energy.

[0033] The display screen, buttons, magnetic charging board, data cable, and charging interface are all electrically connected to the main control module and battery module of the system, together forming a complete portable interactive control terminal.

[0034] The beneficial effects of this invention are: 1. In this invention, by integrating a multi-protocol communication module and a device interaction engine inside the power bank, the power bank can wirelessly interact with and control external mechanical products while charging them. This achieves hardware integration of the charging device and the remote control device, solving the problem that existing mobile charging devices have limited functions and users need to carry separate remote control devices to operate external mechanical products.

[0035] 2. In this invention, the remaining energy of the battery module is monitored in real time by an energy budget arbitrator, and the available control budget of the control channel is dynamically calculated according to the real-time power demand of the charge and discharge management module. This realizes the adaptive allocation of external charging power and wireless control power consumption on the shared energy source, and solves the problem of charging interruption or control failure caused by power consumption competition when the power supply channel and the control channel share battery resources.

[0036] 3. In this invention, the status feedback data and the terminal device usage status data are fused together by the device interaction engine to generate scene tags and output them to the charging and discharging management module to execute differentiated charging strategies. This realizes the linkage adjustment of charging power according to the load status of the terminal device and the working status of external mechanical products, and solves the problem of overheating and frequency reduction of the terminal device under high load scenarios caused by the traditional power bank continuously charging at a fixed power.

[0039] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0040] See appendix Figure 1 To be continued Figure 2 A system for a portable power supply device with wireless interactive control functionality, comprising: The battery module, located within the power bank, stores electrical energy and provides a shared energy source for external charging and wireless interactive control.

[0041] The charge / discharge management module, which is electrically connected to the battery module, is configured to adjust the charging power to the terminal device according to the charging control signal.

[0042] The multi-protocol communication module, integrated inside the power bank, includes a Bluetooth Low Energy communication unit and an infrared transmitter unit. It is configured to establish a wireless connection with external mechanical products, send control commands, and receive status feedback data returned by them.

[0043] The device interaction engine is electrically connected to the multi-protocol communication module, the charge / discharge management module, and the physical interaction interface of the device. It is configured to: fuse status feedback data with the usage status data of the terminal device to generate scene tags, output the scene tags as charging control signals to the charge / discharge management module, and translate the control events generated by the physical interaction interface of the device into control commands and output them to the multi-protocol communication module.

[0044] The physical interface of the device is set on the outer surface of the power bank and is electrically connected to the device interaction engine. It is configured to receive user control input and generate control events.

[0045] The energy budget arbitrator is electrically connected to the battery module, the charge / discharge management module, and the device interaction engine, respectively. It is configured to calculate the available control budget of the control channel based on the remaining energy of the battery module and the real-time power demand of the charge / discharge management module. When the available control budget is lower than a preset threshold, it sends a frequency reduction command to the device interaction engine.

[0046] In one embodiment, the battery module in this solution contains two independent power control channels, each containing two different batteries, named Battery One and Battery Two.

[0047] Battery 1's primary function is to establish a charging channel between the phone and this device, used for charging the phone. Battery 2's primary function is to establish a channel between external devices and the Bluetooth function of this device. Battery 1 and Battery 2 separate Bluetooth power consumption and charging power consumption, avoiding instability in current or interaction signals caused by the device simultaneously establishing a Bluetooth connection and charging the phone.

[0048] The battery module uses 10000mAh lithium-ion polymer cells with a nominal voltage of 3.7V and a total energy of 37Wh. This battery module provides a shared power source for both the 5V / 3A charging output of the USB-C output port and the Bluetooth Low Energy communication unit and infrared transmitter unit of the multi-protocol communication module. Both share the same battery resources and cannot be physically separated for power supply. The charge / discharge management module uses an integrated power management chip to dynamically adjust the charging power of the USB-C output port within the range of 5W to 15W based on the charging control signal corresponding to the scene tag output by the device interaction engine.

[0049] The multi-protocol communication module is integrated onto the PCB board inside the power bank. The Bluetooth Low Energy communication unit operates in the 2.4GHz ISM band, and the infrared transmitting unit uses a 38kHz carrier frequency. Both share the same main control antenna switch. The device interaction engine runs on a low-power microcontroller inside the power bank, using interrupt-driven processing to handle status feedback data from the multi-protocol communication module and control events from the physical interface. The two data paths share the same RAM cache within the microcontroller.

[0050] The physical interface of the device includes a touch-sensitive area and physical buttons on the surface of the power bank. User touch or press operation events are sampled by the ADC and transmitted to the device interaction engine in the form of interrupt signals. The energy budget arbitrator samples the voltage and current of the battery module at a period of 100ms. It calculates the charging channel energy budget based on the real-time power demand of the current USB-C output terminal. The remaining amount after subtracting the charging channel energy budget from the current output power of the battery module is used as the available control budget of the control channel. When the available control budget is lower than the preset threshold of 50mW, a frequency reduction command is sent to the device interaction engine to extend the broadcast interval of the Bluetooth Low Energy communication unit from 20ms to 200ms.

[0051] See appendix Figure 1 To be continued Figure 2 The device interaction engine is configured to perform multi-protocol adaptive switching operations: when the connection signal strength between the Bluetooth Low Energy communication unit and the external mechanical product is lower than a preset threshold, it automatically switches to the infrared transmitting unit to send control commands. When it detects that the external mechanical product supports the near-field communication protocol and the distance is less than the preset safe distance, it prioritizes establishing an encrypted connection through the near-field communication unit.

[0052] In one embodiment, the device interaction engine continuously monitors the RSSI value between the Bluetooth Low Energy communication unit and the currently paired external mechanical product at a period of 500ms. When it detects that the RSSI value is lower than the preset threshold of -70dBm for three consecutive samples, it determines that the Bluetooth link quality is insufficient to reliably transmit control commands. It then automatically switches the control command transmission channel to the infrared transmitting unit. The infrared transmitting unit uses a 38kHz carrier to pulse code modulate the control command and transmits it to the infrared receiving window of the external mechanical product in a line-of-sight manner. Since infrared communication does not depend on the radio frequency signal strength, the continuity of the control link can still be maintained even when the Bluetooth signal is degraded due to metal obstruction or multipath fading.

[0053] When the NFC reader built into the power bank detects an NFC tag attached to the surface of an external mechanical product and the communication distance is less than the preset safe distance of 4cm, it first establishes an encrypted handshake connection through the NFC unit at a carrier frequency of 13.56MHz. The control key is exchanged during the NFC session. Subsequent control commands are still sent through the Bluetooth Low Energy communication unit or the infrared transmitter unit, but they carry the encrypted token negotiated during the NFC session. This establishes a secure channel during the short-range initialization phase and solves the security risk that the key exchange during Bluetooth pairing can be intercepted by a man-in-the-middle.

[0054] See appendix Figure 1 To be continued Figure 2 : Identify the equipment type and current working mode of external mechanical products, and generate equipment status identifiers.

[0055] Obtain the remaining battery power and the type of application currently running on the terminal device, and generate a terminal status identifier.

[0056] The device status identifier and the terminal status identifier are combined and encoded to generate a scene label.

[0057] In one embodiment, the device interaction engine sends a status query command to the connected external mechanical product through a multi-protocol communication module. The data frame returned by the external mechanical product contains a device type field and a current working mode field. The device interaction engine extracts the device type identifier from it. The device type identifier includes three types of coded values: environmental control equipment, lighting equipment, and power tools. At the same time, it extracts the current working mode identifier, which includes three status codes: running, standby, and off.

[0058] The device interaction engine simultaneously obtains the remaining battery percentage and current charging negotiation power of the terminal device through the PD protocol handshake via the USB-C interface, and obtains the type identifier of the foreground application running on the terminal device through Bluetooth connection. The application type identifier includes four types of encoded values: video playback, large-scale games, document editing, and standby. The device interaction engine concatenates the high 4 bits of the device status identifier with the low 4 bits of the terminal status identifier to form an 8-bit scene tag. For example, when the external mechanical product is an environmental control device and is in operation, and the terminal device is running a large-scale game and has 30% remaining battery power, the generated scene tag code is 0x6B. This encoded value is directly output as a charging control signal to the charging and discharging management module. The charging and discharging management module adjusts the charging power to the corresponding target value according to the pre-stored code-power mapping table.

[0059] See appendix Figure 1 To be continued Figure 2 When the scene label indicates that the terminal device is in a high-load application operation state and the external mechanical product is in a working state, the charging power will be reduced to the first power threshold.

[0060] When the scene label indicates that the terminal device is in standby mode and the external mechanical product is in standby mode, the charging power will be reduced to the second power threshold, which is less than the first power threshold.

[0061] In one embodiment, when the scene tag's encoded value indicates that the terminal device is running a high-load application such as a large game or video rendering, and the external mechanical product is a power tool and is in operation, the charge / discharge management module reduces the charging power of the USB-C output to a first power threshold of 5W. Since the terminal device's processor and display screen already generate a lot of heat when running high-load applications, continuing to charge at a high power of 15W will cause the terminal device's surface temperature to exceed the safety threshold of 45°C. After reducing the charging power, the terminal device's temperature rise rate decreases from 1.2°C per minute to 0.4°C per minute. At the same time, the device interaction engine sends a speed reduction command to the external mechanical product through the multi-protocol communication module to reduce its motor speed, thereby reducing heat generation on both the power supply and control sides, solving the problem of terminal device overheating caused by the superposition of charging heat and device operation heat.

[0062] When the scene tag's encoded value indicates that the terminal device is in standby mode and the external mechanical product is in standby mode, the charge and discharge management module further reduces the charging power to the second power threshold of 2W. Since the terminal device has no high-power applications running and the external mechanical product has no energy consumption requirements at this time, low-power trickle charging can meet the terminal device's power maintenance requirements. The saved power margin is redistributed to the control channel by the energy budget arbitrator, enabling the multi-protocol communication module to maintain full-frequency polling to maintain real-time monitoring of the external mechanical product's status.

[0063] See appendix Figure 1 To be continued Figure 2 When the available control budget is higher than the first budget threshold, the control device interaction engine runs in full-speed mode, and the multi-protocol communication module maintains full-frequency communication.

[0064] When the available control budget is lower than the first budget threshold but higher than the second budget threshold, the control device interaction engine operates in a reduced frequency mode, the communication frequency of the multi-protocol communication module is reduced to the first reduced frequency threshold, and the status polling of non-critical external mechanical products is suspended.

[0065] When the available control budget is lower than the second budget threshold, the control channel of the device interaction engine is turned off, and only the charging function of the charge and discharge management module is retained.

[0066] In one embodiment, the energy budget arbitrator sets a first budget threshold of 100mW and a second budget threshold of 30mW for the available control budget. When the available control budget is higher than 100mW, the device interaction engine operates in full-speed mode, the microcontroller's main frequency remains at 64MHz, the Bluetooth Low Energy communication unit of the multi-protocol communication module continuously broadcasts and polls all paired external mechanical products at 20ms intervals, and the infrared transmitting unit is in a ready state to send commands at any time, ensuring that the response latency of user operation is less than 50ms.

[0067] When the available control budget is below 100mW but above 30mW, the device interaction engine switches to a frequency reduction mode, the microcontroller's main frequency drops to 16MHz, the broadcast interval of the Bluetooth Low Energy communication unit is extended from 20ms to 500ms, and status polling of non-critical external mechanical products (such as lighting equipment) is suspended, retaining only the communication link with the target mechanical product currently being operated by the user. This reduces the average power consumption of the control channel from 80mW to 25mW, prioritizing the availability of critical control links when battery energy is limited. When the available control budget is below 30mW, the energy budget arbitrator sends a shutdown command to the device interaction engine, completely cutting off the power supply to the multi-protocol communication module. The device interaction engine enters a sleep state, retaining only the low-power charging function of the charge / discharge management module for the terminal device. This concentrates all the output power of the battery module for charging, ensuring that the terminal device can still receive stable power replenishment even in extreme conditions where the battery is about to run out.

[0068] See appendix Figure 1 To be continued Figure 2 Based on the equipment type identifier of the currently connected external mechanical product, match the corresponding mapping relationship from the pre-stored protocol adapter library.

[0069] The physical interface inputs are translated into control commands for the corresponding external mechanical products according to the mapping relationship.

[0070] The physical interface of the device includes a knob control and a function button group. The rotation operation of the knob control is mapped to the continuous adjustment of the parameters of the external mechanical product, and the pressing operation of the function button group is mapped to the mode switching or on / off control of the external mechanical product.

[0071] In one embodiment, when a user triggers the device pairing mode through the function key group on the physical interaction interface of the device, the device interaction engine obtains the device type identifier of the currently connected external mechanical product from the multi-protocol communication module, and uses this as an index key to look up the corresponding mapping table in the protocol adapter library stored in the internal Flash memory of the power bank. The protocol adapter library pre-stores the control mapping relationships corresponding to three types of devices: environmental control equipment, lighting equipment, and power tools.

[0072] Taking an environmental control device as an example: Clockwise rotation of the knob is mapped to an increment of the temperature setpoint in 0.5°C steps, while counter-clockwise rotation is mapped to a decrement of the temperature setpoint in 0.5°C steps. The knob's rotation angle is sampled by an ADC and quantized into a value range of 0 to 255, corresponding to a continuous temperature setpoint adjustment range of 16°C to 32°C. The first button in the function button group is mapped to a cooling / heating mode switching command, the second button to a fan speed level switching command, and the third button to a device power on / off command. Each time the user rotates the knob or presses a button, the resulting control event is translated by the device's interaction engine into a control command frame conforming to the target device's communication protocol format according to the above mapping relationship. This frame is then sent to the corresponding external mechanical product via a multi-protocol communication module, allowing the user to directly control the external mechanical product from the power bank itself without needing a mobile app.

[0073] See appendix Figure 1 To be continued Figure 2 The safety control module is configured to perform the following safety verification operations before the device interaction engine outputs control commands to the multi-protocol communication module: determine whether the control command belongs to the pre-stored allowed operation whitelist, and determine whether the state of the external mechanical product after executing the control command exceeds the preset safety boundary conditions. Only when the control command passes the above two verifications will the control command be forwarded to the multi-protocol communication module.

[0074] In one embodiment, the security control module is embedded in the data path between the device interaction engine and the multi-protocol communication module in the form of a software interception layer. When the control command frame generated by the device interaction engine arrives at the security control module, the security control module first extracts the opcode field in the command frame and compares it item by item in the allowed operation whitelist stored in Flash. The whitelist contains all the opcodes allowed by the currently connected device type.

[0075] For example, for power tools, the whitelist includes four types of operation codes: start, stop, speed adjustment, and forward / reverse switching. If the operation code is not in the whitelist, the instruction frame is discarded and the user is prompted with "unsupported operation" through the display screen of the physical interface.

[0076] After passing the whitelist verification, the security control module further simulates the device state after execution based on the parameter fields in the instruction frame, and determines whether the state exceeds the preset safety boundary conditions. For example, for the speed adjustment instruction of the power tool, the safety boundary condition is that the speed does not exceed 110% of the rated maximum speed of the device. If the simulated speed exceeds this boundary, the forwarding will be rejected and the user will be prompted that "parameter exceeds the limit". In this way, double security interception is completed before the control instruction reaches the external mechanical product, preventing the external mechanical product from entering a dangerous working condition due to incorrect mapping of the protocol adaptation library or user misoperation.
