Description

Technical Field

[0001] This invention relates to the field of infant and child vehicle technology, and more specifically, to an adjustment method, system, and infant and child vehicle for an electric head canopy. Background Technology

[0002] Infant and toddler vehicles include child safety seats, infant carriers, strollers, and other devices for infants and toddlers to sit in. Headrests are primarily installed on these vehicles to block sunlight, providing a sunshade effect. Electric headrests consist of a front frame, a rear frame, a headrest fabric, and a drive mechanism. The headrest fabric is mounted on both ends of the front and rear frame frames. The rear frame frame can be connected to the seat back via a connector. One end of the front frame frame is pivotally connected to the rear frame frame. The drive mechanism controls the rotation of the headrest fabric relative to the rear frame frame and seat back, thus achieving automatic opening and automatic sunshade / retraction. Currently, most electric headrests are purely manual or have simple electric button controls, which are relatively limited and inconvenient for users traveling alone with a child. Furthermore, during driving (e.g., when the child safety seat moves with the vehicle or an adult pushes a stroller carrying an infant), the headrest cannot adaptively adjust to the direction of travel and lighting conditions, leaving children susceptible to varying degrees of sunlight exposure and affecting their comfort. Summary of the Invention

[0003] To address at least one of the aforementioned problems, the present invention first provides a method for adjusting an electric canopy, comprising the steps of:

[0004] Real-time detection of control signals, including manual mode signals and automatic mode signals;

[0005] Determine whether the detected control signal is an automatic mode signal. If so, detect the light signal in real time and generate a light intensity dataset based on the light signal. Drive the servo motor to automatically rotate the canopy lever according to the light intensity dataset to adjust the rotation angle of the canopy and block the strong light.

[0006] Determine whether the detected control signal is a manual mode signal. If so, control the operation of the headliner lever to adjust the rotation angle of the headliner. The manual mode signal includes one of the following: button control signal, external electronic device control signal, and manual intention recognition control signal.

[0007] Optionally, the step of determining whether the detected control signal is a manual mode signal includes:

[0008] When the manual mode signal is determined to be a manual intent recognition control signal;

[0009] Determine whether a manual adjustment control signal has been detected;

[0010] If a manual adjustment control signal is detected, determine whether an angle feedback signal is detected.

[0011] If the angle feedback signal is not detected, the servo is determined to be a normal servo. Then, it is determined whether the signal of the fully retracted position sensor is detected. If yes, the servo is controlled to rotate the hood to the fully extended state. If no, it is determined whether the signal of the fully extended position sensor is detected. If yes, the servo is controlled to rotate the hood to the fully retracted state.

[0012] If the angle feedback signal is detected, the servo motor is determined to be a servo motor with angle feedback function, and then the real-time angle of the servo motor arm is detected in real time, and it is determined whether the real-time angle of the servo motor arm has changed.

[0013] If the real-time angle of the servo arm changes, the servo is controlled to drive the head canopy lever to rotate in the same direction as the change in the servo arm angle.

[0014] Optionally, after the manual adjustment control signal is detected, the method further includes the following steps:

[0015] Determine whether the duration of the manual adjustment control signal exceeds a preset time threshold.

[0016] If the duration of the manual adjustment control signal exceeds a preset time threshold, the detection angle feedback signal is triggered.

[0017] Optionally, the step of determining whether the detected control signal is a manual mode signal further includes:

[0018] Preset angle step values;

[0019] When the manual mode signal is determined to be a manual intent recognition control signal, if the real-time angle of the servo arm changes, the servo is controlled to drive the head canopy lever to rotate in the same direction as the change in the servo arm angle by one angle step value.

[0020] Optionally, the step of real-time detection of light signals and generation of light intensity datasets based on the light signals includes:

[0021] The light signal is detected in real time by a photosensitive sensor module; the photosensitive sensor module includes multiple photosensitive sensors, and the light signal collected by each photosensitive sensor in the photosensitive sensor module is used to form a light intensity dataset according to a preset algorithm.

[0022] Optionally, the step of driving the servo motor to automatically rotate the canopy lever based on the light intensity dataset to adjust the rotation angle of the canopy and thus block the strong light includes:

[0023] Determine whether the light signal collected by each of the photosensitive sensors is greater than or equal to a preset light threshold; if so, it is determined to be a strong light signal.

[0024] The target angle of the headgear is determined based on the position of the photosensitive sensor that is identified as a strong light signal.

[0025] The servo motor is controlled to rotate the canopy to the target angle.

[0026] Optionally, the method for adjusting the electric canopy also includes the following steps:

[0027] Determine whether a scene linkage command signal in the resting state is detected. If so, control the servo motor to adjust the head canopy to an angle that matches the corresponding mode according to the scene linkage command signal.

[0028] The scene linkage command signal includes the scene mode and / or target parameters;

[0029] The scene modes include a children's rest mode;

[0030] The target parameters include rest duration and hood deployment angle.

[0031] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0032] 1. The manual and automatic modes provide users with clear operation options. The automatic mode frees up the hands, while the manual mode integrates button control, external electronic device control, and innovative intent recognition control, making the control methods flexible and diverse, adaptable to various scenarios such as taking care of children alone, driving, and strong light, greatly improving the convenience of operation.

[0033] 2. In the solution for ordinary servo motor control of the head canopy, position sensors at the extreme positions of full extension and full retraction are used to achieve the function of one-pull operation in the most common scenario (full extension or full retraction) when the power is on, which is achieved at a low cost. This effectively avoids damage to the drive components caused by manual pulling due to accidental operation when the power is on, and also improves the convenience of operation.

[0034] 3. In the solution for controlling the head canopy with Hall effect servo motor, real-time angle feedback enables precise and smooth rotation with manual pulling across the entire angle range. It also allows for preset rotation angle of the head canopy after each pull, effectively preventing damage to the drive components caused by accidental manual pulling while the device is powered on, and providing more precise control.

[0035] 4. Through multiple photosensitive sensors, the system can automatically determine the incident angle and range of strong light and automatically control the awning to rotate to the optimal blocking position, improving comfort and safety, and the driver does not need to be distracted by operating the awning during the entire driving process.

[0036] 5. It can be integrated with the vehicle's infotainment system to enable features such as one-click activation of "child rest mode" and setting the rest duration, as well as automatically completing a series of operations such as headliner adjustment, making it more intelligent and expanding the product's collaborative functions.

[0037] In addition, the present invention provides an adjustment system for an electric hood, for performing the electric hood adjustment method described above, comprising:

[0038] Servo drive module, used to drive the hood to rotate;

[0039] The interaction module is used to receive signals from user input.

[0040] The sensing module is used to collect light signals;

[0041] The control module is communicatively connected to the servo drive module, the interaction module, and the sensing module to control the operation of the canopy based on the received signals.

[0042] Optionally, the servo drive module includes a conventional servo and a limit switch corresponding to the servo arm in the fully extended or fully retracted state; or the servo drive module includes a Hall effect servo with real-time angle feedback function.

[0043] In addition, the present invention provides an infant vehicle, including a seat body, a head canopy disposed on the seat body, and an adjustment system for the electric head canopy as described above.

[0044] Compared to existing technologies, the infant carrier described in this invention and the adjustment method of the electric head canopy described above have the same advantages over existing technologies, which will not be repeated here. Attached Figure Description

[0046] Figure 2 The process of manual intent recognition control in this embodiment of the invention Figure 1 ;

[0047] Figure 3 The process of manual intent recognition control in this embodiment of the invention Figure 2 . Detailed Implementation

[0048] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figure 1-3 This application will be described in further detail.

[0049] In a first aspect, embodiments of the present invention provide a method for adjusting an electric head canopy. The electric head canopy is installed on an infant vehicle, which includes devices for infants to sit in, such as child safety seats, infant carriers, and strollers. This embodiment uses a child safety seat as an example. The elevator head canopy includes a head canopy rod, a head canopy fabric, and a servo motor. The head canopy fabric is connected to the head canopy rod, the head canopy rod is pivotally connected to the child safety seat, and the servo motor is connected to the child safety seat. The servo motor arm is connected to the head canopy rod, and the servo motor arm can rotate to drive the head canopy rod and the head canopy, thereby adjusting the head canopy's unfolding angle.

[0050] Reference Figure 1 and Figure 2 The adjustment method for the electric canopy includes the following steps:

[0051] Real-time detection of control signals, including manual mode signals and automatic mode signals, which can be switched via a mobile app or buttons on the vehicle's infotainment system.

[0052] The system determines whether the detected control signal is an automatic mode signal. If it is, the system will continuously detect the light signal through the photosensor module. The photosensor module includes multiple photosensors, and the light signals collected by each photosensor are used to form a light intensity dataset according to a preset algorithm. The system then determines whether the light signal collected by each photosensor is greater than or equal to a preset light threshold. If so, it is determined to be a strong light signal. The light threshold can be adjusted according to the actual scene.

[0053] The system calculates and determines the target angle of the canopy based on the position of the photosensitive sensor that is identified as a strong light signal; then it controls the servo arm to drive the canopy lever to automatically rotate to the target angle, thereby blocking the strong light.

[0054] In detail, the system incorporates an algorithm based on historical experience to map the data read by the photosensor into two levels: normal light signal and strong light signal. Four photosensor sensors, numbered one, two, three, and four, are deployed on each side of the seat. The installation height of each sensor roughly corresponds to an ideal shading angle (e.g., sensor one corresponds to 0° above the headlights, sensor two to 60°, sensor three to 120°, and sensor four to 160° for near-horizontal front shading). The strong light signal trigger adjustment logic is as follows:

[0055] If No. 1 detects a strong light signal while No. 2 does not, it is determined that the strong light is coming from the front and above at an angle. In order to effectively block the light at this angle without excessively affecting the forward vision, the system controls the canopy to automatically adjust to 60°.

[0056] If No. 1 and No. 2 detect a strong light signal, but No. 3 does not detect a strong light signal, it is determined that the incident angle of the strong light is lower, and the system controls the canopy to automatically adjust to 120°.

[0057] If strong light signals are detected by No. 1, No. 2, and No. 3, but not by No. 4: the system will automatically adjust the canopy to the maximum angle of 160°.

[0058] If the light signal of the sensor corresponding to the strong light signal is less than the preset light threshold (e.g., the vehicle enters the shadow or changes the driving direction) and the duration exceeds the preset duration threshold (e.g., 10 seconds, mainly to prevent the canopy from moving back and forth frequently due to short shadows, such as passing under a bridge), the control servo arm will drive the canopy lever to automatically rotate and perform reverse adjustment (canopy retraction).

[0059] The logic of reverse adjustment is as follows:

[0060] When the head canopy is at 160°, No. 4 and No. 3 do not detect strong light signals and the duration exceeds the preset duration threshold (e.g., 10 seconds), while No. 2 detects strong light signals. The system then controls the head canopy to automatically adjust to 120°.

[0061] When the head canopy is at 120°, No. 4, No. 3 and No. 2 do not detect strong light signals and the duration exceeds the preset duration threshold (e.g., 10 seconds), while No. 1 detects a strong light signal. The system controls the head canopy to automatically adjust to 60°.

[0062] When the head canopy is at 60°, if no strong light signal is detected on devices 4, 3, 2, and 1 and the duration exceeds the preset duration threshold (e.g., 10 seconds), the system will automatically adjust the head canopy to 0° without any manual intervention.

[0063] Reference Figure 1 and Figure 2 The system determines whether the detected control signal is a manual mode signal. Manual mode signals include button control signals, external electronic device control signals, and manual intent recognition control signals. If the detected manual mode signal is any one of the button control signal, external electronic device control signal, and manual intent recognition control signal, the system controls the servo motor to drive the canopy lever to adjust the rotation angle of the canopy.

[0064] The child seat has two buttons to control the deployment and folding of the headliner, respectively. Pressing the button sends a control signal. External electronic device signals include mobile terminals (phones, tablets) and the vehicle's infotainment system. The mobile terminal or vehicle's infotainment system establishes a communication connection with the headliner system via Bluetooth / Wi-Fi. Users can then input commands through the corresponding app on the mobile terminal or vehicle's infotainment system. These commands are converted into control signals for the external electronic devices. Users can create custom automatic adjustment rules on the mobile app (e.g., "If the second photosensor continuously detects strong light for more than 5 seconds, the headliner will automatically adjust to 100 degrees after a 15-second delay"). These automatic adjustment rules can be named and saved. The system stores and executes the corresponding automatic adjustment rules, achieving personalized intelligence beyond fixed logic. The manual intent recognition control signal is the tension applied to the headliner lever.

[0065] Reference Figure 1 and Figure 2 The steps to determine whether the detected control signal is a manual mode signal include:

[0066] When the manual mode signal is determined to be a manual intent recognition control signal, the system checks whether a manual adjustment control signal is detected. If a manual adjustment control signal is detected, the system checks whether the duration of the manual adjustment control signal exceeds a preset time threshold (e.g., the time threshold is set to 1 second, where the system reads the status every 100ms; if the status changes after 10 consecutive reads, it is determined to be manually applied). If the duration of the manual adjustment control signal exceeds the preset time threshold, the system checks whether an angle feedback signal is detected. If no angle feedback signal is detected, the servo is determined to be a normal servo. The system then determines whether a signal from the fully retracted position sensor is detected. If so, it controls the servo to rotate the hood to the fully extended state. If not, it determines whether a signal from the fully extended position sensor is detected. If so, it controls the servo to rotate the hood to the fully retracted state. If an angle feedback signal is detected, it determines that the servo is a servo with angle feedback function (Hall effect servo). It then detects the real-time angle of the servo arm and determines whether the real-time angle of the servo arm has changed. If the real-time angle of the servo arm changes, it controls the servo to rotate the hood lever in the same direction as the change in the servo arm angle.

[0067] In this system, when the servo is a standard servo, the position sensor acts as a limit switch. Limit switches are installed at the two extreme positions of the servo arm: fully extended and fully retracted. When powered on and the canopy is at its extreme position, the servo arm presses down on the corresponding limit switch. When the user pulls the canopy lever, the servo arm undergoes a slight displacement, changing the limit switch status. The system detects this signal and, after determining that the current servo has no angle feedback function (i.e., a standard servo), checks the limit switch status. If the limit switch for the "fully retracted" position is detected as triggered (i.e., the canopy is fully retracted), the user pulling the canopy outward will cause a slight displacement of the servo arm, disengaging the limit switch. After capturing this status change signal, the system determines that the user's intention is "extension," and thus drives the servo to rotate forward until the canopy is fully extended (triggering another limit switch). Conversely, if the canopy is fully extended, pushing it inward will trigger a change in the limit switch of the "fully extended" position. The system will then drive the servo motor to rotate in the opposite direction until it is fully retracted. By cleverly utilizing the mechanical structure at the limit position, the intuitive operation of "opening with a light pull and closing with a light push" is achieved at low cost, greatly improving convenience.

[0068] When the servo is a Hall effect servo, the angle sensor integrated inside the Hall effect servo can provide real-time feedback of the servo output shaft angle value to the system. After detecting the adjustment intention in manual mode, the system confirms the existence of the angle feedback signal and then enters the Hall effect servo processing logic. The system continuously reads the real-time angle value of the servo. When the user pulls the hood in a certain direction, it will force the servo shaft to produce a small angular displacement. By periodically sampling (e.g., once every 100ms), the angle change can be detected. At the same time, in order to prevent false triggering caused by vehicle bumps, regardless of whether the servo is a regular servo with a limit switch or a Hall effect servo, the system will determine whether this angle change continues for a preset time threshold (e.g., for more than 1 second, the sampled angles all cumulatively change in the same direction exceeding a minimum threshold). Once it is confirmed as a continuous user intention, the system immediately controls the servo to actively rotate the hood in the same direction as the direction of the change in the servo arm angle to either fully extended or fully retracted.

[0069] Reference Figure 3 Preferably, the step of determining whether the detected control signal is a manual mode signal further includes:

[0070] There is a preset angle step value; when the manual mode signal is determined to be a manual intention recognition control signal, if the real-time angle of the servo arm changes, the servo will be controlled to drive the head canopy rod to rotate in the same direction as the change in the servo arm angle by an angle step value.

[0071] Users can preset an angle step value (such as 30°) through the APP. When the manual intention recognition control signal is recognized, the servo does not rotate to the limit (fully extended or fully retracted state), but precisely rotates the preset step angle and then stops. This allows users to make fine and personalized angle adjustments by "pulling a little and moving a little" at any starting angle, resulting in a smooth and precise operating experience.

[0072] Optionally, the method for adjusting the electric canopy also includes the following steps:

[0073] The status information of the headliner is fed back to the user in real time through at least one of the following methods: indicator lights, mobile terminal, or vehicle application; the status information includes at least one of the following: current angle, servo motor working status, sensor status, and preset scene execution progress.

[0074] The seats can be equipped with multi-color LED indicator lights. For example, a solid blue light indicates manual mode, a solid green light indicates automatic mode, a breathing flashing light indicates automatic adjustment is in progress, and a flashing red light indicates a malfunction (such as steering gear jamming or sensor abnormality). Meanwhile, the connected mobile app or vehicle infotainment system will display more detailed information graphically, such as the real-time angle of the headliner (digital or analog gauges), the current light intensity level, the operating mode, and the progress of preset scenarios (e.g., "Delayed adjustment in progress, 5 seconds remaining").

[0075] Optionally, the method for adjusting the electric canopy also includes the following steps:

[0076] Determine whether a scene linkage command signal in the resting state is detected. If so, control the servo to adjust the headliner to an angle that matches the corresponding mode according to the scene linkage command signal. The scene linkage command signal includes the scene mode and / or target parameters. The scene mode includes the child rest mode. The target parameters include the rest duration, the headliner unfolding angle, and the in-vehicle air conditioning temperature.

[0077] Users can select "Child Rest Mode" on the vehicle's infotainment system and set the duration (e.g., 45 minutes). The infotainment app sends a linkage command to the seat system via Bluetooth or the vehicle network. Upon receiving the command, the system first checks if a preset headliner rotation angle is available. If so, the system controls the headliner to rotate to the preset angle; otherwise, it automatically adjusts the headliner to the optimal sunshade angle based on the current light intensity dataset. Simultaneously, the infotainment app sends a command to the vehicle's air conditioning system via the vehicle bus (e.g., CAN). The air conditioning system first checks if a self-set air conditioning temperature signal is detected. If so, it adjusts the air conditioning temperature to the value corresponding to the self-set signal; otherwise, it executes the preset air conditioning temperature value (e.g., 24℃) and adjusts the airflow mode accordingly. During rest mode, the infotainment screen displays a countdown, the current headliner angle, and the air conditioning settings for easy user control. After the mode ends, the system automatically restores the headliner and air conditioning to their previous states. This function enables cross-device, scenario-based one-click control, greatly enhancing the user experience.

[0078] It is worth noting that when the electric canopy is installed on the trolley, the steps for the electric canopy to interact with the scene include:

[0079] The system determines whether a scene-linked command signal for the resting state is detected. If so, it controls the servo motor to adjust the headliner to the angle appropriate for the corresponding mode. Scene-linked command signals can be sent via a mobile app. The app includes a child rest mode button and a button to adjust the rest duration, allowing for one-click adjustment. In rest mode, the app displays a countdown timer. When the countdown reaches 1 minute (user-defined), the phone vibrates or rings to remind the user and displays a pop-up window asking whether to continue the rest mode. The user can then observe the child's resting state to decide whether to continue and send a command to the system. If the rest mode is continued, a rest duration setting window appears for the user to set the duration. If the rest mode is not continued, the headliner automatically returns to its previous state once the system receives a countdown completion signal.

[0080] Additionally, if the infant carrier can be installed on a car seat to function as a child safety seat, then the steps for installing the electric headrest on the infant carrier and linking it to the scene are the same as the steps for linking the electric headrest on a child safety seat, and will not be repeated here.

[0081] If the infant carrier cannot be installed on a car seat to function as a child safety seat, then the steps for installing the electric headrest and setting up the scene are the same as those for setting up the electric headrest on a stroller, and will not be repeated here.

[0082] Secondly, another embodiment of the present invention provides an adjustment system for an electric awning, used to perform the adjustment method for the electric awning described in the first aspect, comprising:

[0083] Control module: As the core of the system, it is usually a microcontroller (MCU) responsible for signal processing, logic judgment and issuing control commands.

[0084] Servo drive module: includes servos and servo arms that communicate with the control module and are used to drive the head canopy to rotate.

[0085] Interaction module: Includes physical buttons that communicate with the control module and wireless communication units (such as Bluetooth / Wi-Fi chips) for connecting the mobile APP and the vehicle system to receive user input signals.

[0086] Sensing module: includes multiple photosensitive sensors arranged on the left and right sides of the seat for collecting light signals.

[0087] Power supply and feedback module: including power management circuit and indicator lights.

[0088] In one embodiment, the servo motor can be configured as a regular servo motor, and is equipped with limit switches corresponding to the servo arm in the fully extended or fully retracted state (this solution is suitable for users' common extreme position operation scenarios, making operation more convenient and cost controllable); in another embodiment, the servo motor can be configured as a Hall effect servo motor with real-time angle feedback function (precise operation, fast response and long life).

[0089] Thirdly, the present invention provides an infant carrier, including an infant carrier body, a head canopy disposed on the infant carrier body, and an adjustment system for the electric head canopy as described in the second aspect.

[0090] Infant and toddler vehicles include child safety seats, infant carriers, strollers, and other devices for infants and toddlers to ride in.

[0091] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
