Description

Technical Field

[0001] This utility model relates to the field of intelligent baby carrier technology, specifically an intelligent control box device for controlling the above-mentioned functional modules and providing multiple human-computer interaction methods. Background Technology

[0002] Traditional baby carriers or hip seats rely primarily on mechanical structures and fabric support for their functionality. They generally do not include electronic controls, and users lack an interface for interacting with the carrier.

[0003] With the development of intelligent technology, smart baby carriers integrating active functional modules (such as pressure sensing, airbag adjustment, and vibration massage) have emerged. These products face a new challenge: the need for a unified control center to coordinate and manage multiple electronic modules and meet users' interactive needs in different usage scenarios. For example, when holding an infant or with limited hands, users need to be able to perform immediate control via simple, blind-operation physical buttons; while for fine-tuning settings or remote monitoring, they desire more comprehensive operation and status viewing through mobile applications.

[0004] Currently available commercially available products rarely offer control solutions that simultaneously support local physical operation and remote wireless control, while also integrating features such as safety locks and clear status feedback for childcare scenarios. Therefore, there is an urgent need to develop a highly integrated, versatile, and reliable control system to adapt to the development of smart baby carrier products. Based on the aforementioned issues, we propose a smart baby carrier and its interactive control system. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0013] The air pump and solenoid valve are electrically connected to the microcontroller via a drive board, and are used to drive the airbag inflation / deflation device;

[0014] The control unit is electrically connected to the microcontroller and is used to control the vibration massage device;

[0015] The surface of the control box is provided with operation buttons and status indicator components that are electrically connected to the microcontroller.

[0016] Furthermore, the control box is waterproof and dustproof, and its outer shell has a hook or slide rail for detachable installation on the chest of the shoulder strap; the control box is a small box-shaped module with a rounded corner anti-collision design on its outer shell.

[0017] Furthermore, the main control circuit board integrates a pressure sensor interface for connecting pressure sensors at the shoulder and waist of the shoulder strap; and transmits the received sensor data to the microcontroller.

[0021] Furthermore, the operation buttons support a child lock mode. When the child lock mode is enabled, the status indicator component displays a lock icon or a specific flashing pattern to remind the user.

[0022] The child lock mode is deactivated by pressing and holding the power button or pressing a specific combination of buttons;

[0023] The operation buttons are made of silicone and have backlighting or tactile bumps.

[0024] The operation buttons are used to manually input control commands for the airbag inflation / deflation device and the vibration massage device.

[0025] Furthermore, the status indication component includes an LED indicator group and a display screen;

[0053] The control box has a housing with hooks or slide rails, and can be detachably installed on the chest of the shoulder strap for easy operation, charging and maintenance.

[0054] The control box is a small box-shaped module with a rounded corner anti-collision design and is made of a sturdy, drop-resistant, and waterproof material.

[0055] The main control circuit board integrates a pressure sensor interface for connecting pressure sensors at the shoulder and waist of the shoulder strap; and transmits the received sensor data to the microcontroller (MCU);

[0056] The microcontroller (MCU) contains control logic that is used to acquire data from each sensor, determine thresholds, and execute corresponding actions.

[0057] The Bluetooth module (BLE) is used to establish a wireless data connection with the mobile terminal, enabling the mobile terminal to remotely monitor the status of the strap and send control commands.

[0058] The mobile terminal is a smartphone with a control application installed or a mobile device running a mini-program.

[0059] The Bluetooth module (BLE) supports encrypted pairing and automatic reconnection after disconnection;

[0060] Through the mobile terminal, users can view the shoulder strap sensor data (shoulder pressure, airbag inflation level, massage intensity) in real time and adjust parameters (allowing users to adjust the shoulder pressure threshold, select massage mode and timer duration, and view historical usage statistics), forming two control interaction methods: operation buttons and mobile terminal application.

[0061] The buzzer is used to provide auditory feedback when the user presses a button or the remote operation of a mobile terminal is successfully executed.

[0062] The vibration alert is used to provide tactile feedback when the user presses a button or performs a remote operation on a mobile terminal.

[0063] The operation buttons support child lock mode. When child lock mode is enabled, the status indicator component displays a lock icon or a specific flashing pattern to remind the user.

[0064] The child lock mode is deactivated by pressing and holding the power button or pressing a specific combination of buttons;

[0074] The mobile app interface provides a dashboard display, such as current shoulder pressure reading (kg or pressure unit), shoulder airbag inflation percentage, lumbar airbag status, massage mode / intensity, and battery level.

[0075] Users can perform the same operations as the control box buttons through the mobile app: set the shoulder airbag trigger threshold, adjust the lumbar airbag inflation level, select massage intensity and timer length, switch between shoulder strap / lumbar stool mode, and even upgrade the firmware.

[0076] The mobile app also records historical data, such as the number of times the stress-relief function is used in a day and the cumulative carrying time, helping users understand their usage habits. For users who are not good at installing apps, a WeChat mini-program has been developed as an alternative, which can be used without installation. The introduction of the main functions to mobile terminals allows this smart shoulder strap to truly integrate into the IoT ecosystem, realizing the linkage between people, devices, and mobile phones.

[0077] The system supports a function to cancel accidental operation: when a user performs an inflation or massage start operation, the previous instruction can be canceled if the same operation button is pressed again within the set time window.

[0078] The status indicator component and buzzer are used to issue audible and visual alarm signals when the power management module detects that the power is below a preset threshold or the driver board detects an abnormal air pressure.

[0079] The control box's display interface and mobile terminal application support multilingual switching.

[0080] Working principle: The user presses and holds the power / mode control button on the control box to start the system; the power management module supplies power to the microcontroller (MCU), sensors and all peripheral circuits;

[0081] The microcontroller (MCU) performs a self-test, the LED indicator group in the status indicator component will flash in a sequential manner, the display screen will light up and show the startup logo, current battery level and default mode (such as strap mode).

[0082] After the self-test passes, the system enters standby mode; the Bluetooth module (BLE) begins broadcasting, waiting to pair and connect with the mobile terminal (mobile app or WeChat mini program); the inertial measurement unit (IMU) and pressure sensor interface begin to collect data continuously or intermittently;

[0083] Users can control the system in two ways:

[0084] A. Local button operation process:

[0085] Inflation Adjustment: When the user briefly presses the inflation / deflation control button, the microcontroller (MCU) receives the signal and immediately activates the air pump and corresponding solenoid valve through the driver board to inflate the target airbag. At the same time, the buzzer emits a short "beep" sound, the vibration indicator vibrates slightly once, the LED indicator enters the breathing flashing mode, and the display screen updates the pressure value in real time. When the preset pressure is reached or the user presses the stop button again, the air pump stops, the buzzer and vibration indicator provide feedback again, and the LED remains lit.

[0086] Massage control: When the user presses the massage control button briefly, the microcontroller (MCU) will then activate the vibration massage device through the control unit; the user can switch between different massage intensity modes by pressing and holding the button for a long time; each operation is accompanied by auditory (buzzer) and tactile (vibration indicator) feedback;

[0087] Mode switching: Users can switch between the preset modes of "shoulder strap mode" and "waist stool mode" by pressing the power / mode control button briefly. The display screen and LED indicator group will update the current mode status simultaneously.

[0088] B. Remote control process using mobile terminals:

[0089] After the user opens the control app or mini-program on the mobile terminal and establishes a Bluetooth connection with the control box, the interface dashboard displays data such as shoulder pressure, airbag inflation level, and battery level transmitted from the control box in real time.

[0090] When a user sets parameters (such as adjusting the shoulder pressure threshold to 5kg) or sends a command (such as starting a 10-minute waist massage) on the App, the command is sent to the microcontroller (MCU) via the Bluetooth module (BLE).

[0091] After the MCU parses the instructions, it executes the corresponding actions. For example, when the pressure sensor data exceeds the set 5kg threshold, it automatically triggers the shoulder airbag to inflate until the pressure drops below the threshold. The status changes throughout the process are fed back to the mobile terminal interface in real time.

[0092] During system operation, the inertial measurement unit (IMU) continuously collects the user's motion acceleration and angular velocity data and sends them to the microcontroller (MCU).

[0093] The software algorithm built into the microcontroller (MCU) analyzes this data to determine in real time whether the user is stationary, walking, or running.

[0094] When the algorithm detects that the user is walking or running, the microcontroller (MCU) will automatically delay or disable the start of the vibration massage function; if the massage is in progress, it will gently stop the current massage and notify the user through a vibration alert; this is to avoid the massage from interfering with the user's balance and to ensure safety.

[0095] If a user accidentally activates inflation or massage, and then triggers the same button again within a set time window (e.g., 3 seconds), the microcontroller (MCU) will interpret it as a cancellation instruction and immediately stop the operation.

[0096] Users can activate the child lock mode by pressing and holding a specific key combination. The microcontroller (MCU) will lock all key inputs; the status indicator component will display a lock icon; in this mode, any key operation is invalid, effectively preventing infants and young children from accidentally touching the key.

[0097] The overpressure protection module on the drive board monitors the airbag pressure in real time. Once the pressure exceeds the safety threshold, the module will send an emergency signal directly to the microcontroller (MCU). The microcontroller (MCU) will immediately stop the air pump and drive the buzzer to emit a continuous alarm sound. At the same time, the status indicator component will flash a red warning.

[0098] The power management module continuously monitors the lithium battery level. When the level drops below a preset value, the microcontroller (MCU) displays a low battery icon on the screen and drives a buzzer to sound intermittently to remind the user to charge the battery in time. The module also provides overcharge and over-discharge protection, automatically cutting off the circuit to protect the battery.

[0099] Status indicator components (LED lights, display screen) and feedback modules (buzzer, vibration alert) continuously provide users with system status information, enabling clear human-computer interaction;

[0100] The Bluetooth module (BLE) will automatically attempt to reconnect when the connection is lost, ensuring the stability of the control and data channel between the mobile terminal and the control box until the system is powered off.
