[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0051] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0052] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0053] As disclosed in the background section, child safety seats with a sliding backrest still have the following problems in actual use: after the parent carries the child out of the seat with both hands, they still need to manually push the backrest back into place with one hand or other part of their body. This is not only inconvenient to operate, but also poses a safety hazard. Embodiments of this application provide a control method for a child safety seat, at least to solve this technical problem.

[0054] Please refer to Figures 1-3. An embodiment of this application provides a control method for a child safety seat, which is applied to a child safety seat. The child safety seat includes a seat base 100, a seat back 200 movably disposed on the seat base 100, and a drive mechanism for driving the seat back 200 to move. The seat base 100 or the seat back 200 is provided with a detection device for detecting when a child leaves the seat.

[0055] A rotating disk 110 is rotatably mounted on the seat base 100. The rotation of the rotating disk 110 is driven by a motor or other driving components. The seat back 200 is slidably mounted on the rotating disk 110 so that the seat back 200 slides out and retracts in the horizontal direction. A driving mechanism is used to drive the seat back 200 to slide out and retract. A detection device is used to detect whether the child has left the seat.

[0056] The child safety seat also includes a controller, which is electrically connected to both the drive mechanism and the detection device, enabling the control method described above. The controller can be an integrated circuit chip with signal processing capabilities. This controller can be a general-purpose processor, including a central processing unit (CPU), or it can be a microcontroller, microcontroller unit, complex programmable logic device (CPL), field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), embedded ARM, or other similar chips.

[0057] Please refer to Figure 4. This control method includes:

[0058] Step S1: Obtain the signal sent by the detection device.

[0059] Step S2: Determine whether the seat back 200 is in the slid-out position.

[0060] Step S3: If it is determined that the seat back 200 is in the slid-out position, control the drive mechanism to drive the seat back 200 back to the initial position.

[0061] In the above steps, the controller acquires the signal sent by the detection device in real time. When the parent takes the child off the seat back 200 with both hands, the controller acquires the signal sent by the detection device. At this time, the controller determines whether the seat back 200 is in the slid-out position. If it is determined that the seat back 200 is in the slid-out position, the controller controls the drive mechanism to drive the seat back 200 back to the initial position. Thus, the seat back 200 can be automatically controlled to return to its original position without additional operation, reducing the difficulty of operation and avoiding the safety hazard of the parent having to manually push the seat back 200 back while holding the child.

[0062] In some embodiments, the detection device is a snap-fit ​​detection device, and step S1 includes: acquiring a signal sent by the snap-fit ​​detection device that indicates that the snap-fit ​​is open.

[0063] The seat back 200 is equipped with buckles for restraining children. A buckle detection device is used to detect whether the buckle is open. The buckle detection device is electrically connected to the controller. Once the buckle detection device detects that the buckle is open, the controller can obtain the signal sent by the buckle detection device indicating that the buckle is open. If it is determined that the seat back 200 is already in the slid-out position, the controller will control the drive mechanism to drive the seat back 200 back to the initial position.

[0064] In some embodiments, the detection device is a human infrared sensor, and step S1 includes: acquiring a signal sent by the human infrared sensor indicating the absence of a human body.

[0065] The human infrared sensor is used to detect whether there is a human body on the seat back 200. The human infrared sensor is electrically connected to the controller. Once the human infrared sensor detects that there is no human body on the seat back 200, the controller can obtain the signal sent by the human infrared sensor indicating that there is no human body. If it is determined that the seat back 200 is already in the slide-out position, the controller will control the drive mechanism to drive the seat back 200 back to the initial position.

[0066] In some embodiments, the detection device is an ambient light sensor, and step S1 includes: acquiring a signal sent by the ambient light sensor that indicates an increase in light intensity.

[0067] An ambient light sensor is used to detect the light intensity around the seat back 200. When a child sits on the seat back 200, the light intensity around the seat back 200 remains relatively stable due to the child's body blocking the light. When the child gets off the seat, the light intensity detected by the ambient light sensor will suddenly increase and change significantly. The amount of change in light intensity can be determined according to the actual product usage.

[0068] The ambient light sensor is electrically connected to the controller. Once the ambient light sensor detects a sudden increase in light intensity and a large change, the controller can obtain the signal sent by the ambient light sensor indicating an increase in light intensity. If it is determined that the seat back 200 is already in the slide-out position, the controller will control the drive mechanism to drive the seat back 200 back to the initial position.

[0069] In some embodiments, the detection device is a Bluetooth module, and step S1 includes: acquiring a signal sent by the Bluetooth module indicating that the Bluetooth connection has been disconnected.

[0070] The Bluetooth module is used to establish a Bluetooth connection with the parent's mobile phone or the child's smart bracelet or other Bluetooth devices. When the parent picks up the child and moves away from the seat to a certain distance, the Bluetooth module will disconnect from the parent's mobile phone or the child's smart bracelet or other Bluetooth devices.

[0071] The Bluetooth module is electrically connected to the controller. Once the Bluetooth module disconnects from the Bluetooth device such as the parent's mobile phone or the child's smart bracelet, the controller can obtain the signal sent by the Bluetooth module indicating that the Bluetooth connection has been disconnected. If it is determined that the seat back 200 is already in the slid-out position, the controller will control the drive mechanism to drive the seat back 200 back to the initial position.

[0072] In some embodiments, a micro switch is provided on the seat base 100 or the seat back 200. The micro switch is used to be triggered during the movement of the seat back 200. Step S2 includes: determining whether the seat back 200 is in the slide-out position based on the triggering state of the micro switch.

[0073] A trigger plate can be installed on the seat back 200, and a micro switch is installed on the seat base 100. During the movement of the seat back 200, the trigger plate abuts against the micro switch to trigger the micro switch. When the micro switch is triggered, the seat back 200 is in the slid-out position.

[0074] The micro switch is electrically connected to the controller. Once the micro switch is triggered, the controller determines that the seat back 200 is in the slid-out position.

[0075] In other embodiments, the micro switch may be replaced by a photoelectric switch, a Hall sensor, a reed switch, etc.

[0076] In some embodiments, the drive mechanism includes a motor, and step S2 includes: obtaining the number of rotations of the motor, and determining whether the seat back 200 is in the slide-out position based on the number of rotations of the motor.

[0077] The motor is electrically connected to the controller. During rotation, the motor sends the number of rotations to the controller. The controller can determine whether the seat back 200 is in the slide-out position based on the difference between the number of rotations of the motor when the seat back 200 is in the initial position and the current number of rotations.

[0078] Once the difference between the number of rotations of the motor and the current number of rotations when the seat back 200 is in the initial position reaches a preset value, the controller determines that the seat back 200 is in the slide-out position.

[0079] In an optional embodiment, when the seat back 200 is in the initial position, the controller resets the number of rotations of the motor to zero, so that the current number of rotations of the motor is consistent each time the seat back 200 reaches the slide-out position. As long as the motor reaches the current number of rotations, the controller can determine that the seat back 200 is in the slide-out position.

[0080] In some embodiments, a displacement sensor for detecting the sliding distance of the seat back 200 is provided on the seat base 100 or the seat back 200. Step S2 includes: determining whether the seat back 200 is in the sliding position based on the signal sent by the displacement sensor.

[0081] The displacement sensor detects the sliding distance of the seat back 200 as it slides from the initial position to the sliding position, and sends the sliding distance signal of the seat back 200 to the controller. When the sliding distance of the seat back 200 from the initial position reaches the preset distance, the controller determines that the seat back 200 is in the sliding position.

[0082] Please refer to Figure 5. This control method also includes:

[0083] Step S4: Determine whether the seat back 200 has returned to its initial position based on the signal sent by the displacement sensor.

[0084] Step S5: If it is determined that the seat back 200 has returned to the initial position, a positioning information is sent.

[0085] It should be noted that the displacement sensor detects the sliding distance of the seat back 200 as it slides from the extended position back to the initial position, and sends this distance signal to the controller. When the seat back 200 has slid a preset distance from the extended position, the controller determines that the seat back 200 is in the initial position. When the controller determines that the seat back 200 has returned to the initial position, it issues a positioning notification to the user; this notification can be an audible or visual signal.

[0086] In some embodiments, a sound sensor is provided on the seat base 100 or the seat back 200 for detecting the sound generated during the movement of the seat back 200. Step S2 includes: determining whether the seat back 200 is in the slide-out position based on the signal sent by the sound sensor.

[0087] It should be noted that during the process of the seat back 200 sliding out and retracting, the seat back 200 will generate different frequencies of sound when it moves to different positions. When the seat back 200 slides out to the sliding position, it will generate a sound of a preset frequency. The sound sensor is used to detect the sound of the seat back 200 during its movement in real time and send the sound signal to the controller. The controller can use a sound recognition algorithm to analyze the frequency of the sound. If the controller analyzes that the frequency of the sound is the preset frequency, it will determine that the seat back 200 is in the sliding position.

[0088] Please refer to Figure 6. In some embodiments, the child safety seat includes a timer, and step S3 includes:

[0089] Sub-step S31: If it is determined that the seat back 200 is in the slid-out position, control the timer to start timing until the timer finishes timing.

[0090] Sub-step S32: Control the drive mechanism to drive the seat back 200 back to the initial position.

[0091] The timer is electrically connected to the controller, and the timer can perform forward or countdown counting.

[0092] When the timer is counting down, if it is determined that the seat back 200 is in the slid-out position, the timer starts counting down. After the countdown ends, the controller controls the drive mechanism to drive the seat back 200 back to the initial position.

[0093] When the timer is counting down, if it is determined that the seat back 200 is in the slid-out position, the timer starts counting down. After the countdown is complete, the controller controls the drive mechanism to drive the seat back 200 back to the initial position.

[0094] Using a timer to control the seat back to retract 200 degrees after the timer ends allows parents enough time to tidy up items or perform other tasks after taking the child away.

[0095] The timing duration can be set according to actual needs. For example, users can set the timing duration through the operation buttons on the seat or a mobile APP. The timing duration can be selected from 5 to 60 seconds.

[0096] When the detection device is a human infrared sensor, if it is determined that the seat back 200 is in the slid-out position, the timer is controlled to start timing. If no new human body is detected approaching during the timing process, the controller controls the drive mechanism to drive the seat back 200 back to the initial position after the timing is completed.

[0097] When the detection device is a Bluetooth module, if it is determined that the seat back 200 is in the slid-out position, the timer is controlled to start timing. If no new Bluetooth connection request is detected during the timing process, the controller controls the drive mechanism to drive the seat back 200 back to the initial position after the timing is completed.

[0098] When the detection device is an ambient light sensor, if it is determined that the seat back 200 is in the slid-out position, the timer is controlled to start timing. If the light intensity detected by the ambient light sensor does not change significantly during the timing process, the controller controls the drive mechanism to drive the seat back 200 back to the initial position after the timing is completed.

[0099] Further, sub-step S31 includes: if it is determined that the seat back 200 is in the slid-out position, controlling the timer to alternate between timing and stopping timing until the total running time of the timer reaches the preset duration.

[0100] If the controller determines that the seat back 200 is in the slid-out position, the controller first controls the timer to start timing. After the timing (e.g., 0.5 seconds) is completed, the controller controls the timer to stop timing. After the timing stops for a period of time (e.g., 2 seconds), the controller controls the timer to start timing again. This cycle continues until the total running time of the timer reaches the preset time (e.g., 5 seconds). The total running time of the timer includes the timing time and the time when the timing stops.

[0101] Using an intermittent timing method allows the timer to switch between working and non-working states, which helps reduce the power consumption of the timer.

[0102] In some embodiments, the child safety seat includes a battery, which is electrically connected to a detection device to supply power to the detection device; step S3 includes: if it is determined that the seat back 200 is in the slid-out position, controlling the drive mechanism to drive the seat back 200 back to the initial position according to the change in battery charge.

[0103] The battery, built into the child safety seat, powers the detection device; therefore, its charge gradually decreases during operation. The battery can be charged via an external power source when its charge is low.

[0104] The battery is electrically connected to the controller, which can obtain the battery's power information. If it is determined that the seat back 200 is in the slid-out position, the controller starts to monitor the changes in the battery's power. When the battery's power drops to a certain level (e.g., the battery's power drops by 5%), the controller controls the drive mechanism to drive the seat back 200 back to the initial position.

[0105] The method of dynamically delaying based on the actual battery charge eliminates the need to set additional time parameters and ensures that the seat backrest 200° retraction function operates normally when the battery charge is low.

[0106] In some embodiments, the control method further includes: acquiring a signal sent by the drive mechanism indicating that the seat back 200 has encountered resistance during the process of the seat back 200 retracting to the initial position; and issuing an alarm message when the signal indicating that the seat back 200 has encountered resistance is acquired.

[0107] The signal sent by the drive mechanism indicating that the seat back 200 is obstructed can be a current feedback signal sent by a sensor (such as a grating or encoder disk) on the motor shaft when the motor is obstructed. When the controller obtains the signal that the seat back 200 is obstructed, the controller issues an alarm message to alert the user. The alarm message can be an audible message or a visual message.

[0108] In summary, this application provides a control method for a child safety seat. When a parent takes the child off the seat back 200 with both hands, the controller receives a signal from the detection device. At this time, it determines whether the seat back 200 is in the slid-out position. If it is determined that the seat back 200 is in the slid-out position, the controller drives the drive mechanism to push the seat back 200 back to the initial position. This allows the seat back 200 to be automatically controlled to return to its original position without additional operation, reducing the difficulty of operation and avoiding the safety hazard of having to manually push the seat back 200 back while holding the child.

[0109] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
