Description

Technical Field

[0001] This invention belongs to the automotive field, specifically relating to an intelligent linkage storage system for automotive headrests and its control method, equipment, and medium. Background Technology

[0002] With the rapid development of intelligent and electric new energy vehicles, the function of car seats has extended from traditional seating comfort to multi-functional and scenario-based features. Current mainstream seat systems, through embedded motors and electronic control units (ECUs), have achieved basic intelligent configurations such as electric adjustment, memory function, heating, and ventilation. Some high-end models further integrate "rest mode," "camping mode," and "bed mode," using multi-dimensional electric adjustment mechanisms to achieve combined actions such as adjusting the seat back angle, extending the leg rest, and providing lumbar support, creating an immersive scenario experience. However, in the process of upgrading seats to be more intelligent, headrest technology still uses traditional mechanical structures, which has the following technical shortcomings:

[0003] First, the headrest is completely disassembled manually, requiring pressing the unlocking buckle and pulling it out at the same time. The process is cumbersome and extremely unfriendly to the elderly and children with less strength. Secondly, the removed headrests can only be temporarily placed in the second row of seats or the trunk, lacking dedicated storage space. Their fixed shape cannot be compressed, resulting in them occupying a lot of interior space in camping or cargo-carrying scenarios, seriously affecting the space utilization efficiency in scenarios such as loading camping equipment and moving. Furthermore, existing headrest systems cannot achieve intelligent linkage with other functional modules of the seat. When switching seat modes, the headrest needs to be handled separately, which seriously affects the user experience. Especially in special scenarios such as the double bed mode, traditional headrests not only prevent the seat from fully reclining, but their awkward shape also affects overall comfort.

[0004] To address the aforementioned issues, a smart, interconnected car headrest storage system that can overcome at least one of the above defects is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide an intelligent linkage storage system for automotive headrests, as well as its control method, equipment and medium, which effectively solves the problems of manual intervention required for disassembly and storage, the headrest still occupying cabin space, and the lack of dynamic linkage between the headrest and the seat posture.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. It should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of the present invention.

[0019] In existing technologies, car seat headrests are typically fixed to the top of the seat back using mechanical clips, requiring users to manually press the unlocking device and pull it out to remove it. Because of their fixed size and lack of dedicated storage space, the removed headrests are often placed in the seat area or trunk, compressing the usable interior space for scenarios such as camping or carrying cargo. Especially in new energy vehicles with integrated double-bed configurations, traditional headrests cannot automatically retract with changes in seat shape, requiring repeated user intervention and impacting the efficiency of scene switching. Therefore, this invention proposes an intelligent linkage storage system for car headrests, along with its control method, device, and medium. The invention will be further described in detail below with reference to the accompanying drawings.

[0020] First, refer to Figure 1 This invention describes an intelligent linked storage system 100 for car headrests according to some embodiments of the present invention.

[0021] like Figure 1 As shown, the intelligent linkage storage system 100 for car headrests in this invention includes: a storage compartment (not shown in the figure), a headrest assembly 110, a drive module 120, and a control module 130; A storage compartment, located inside the back of the car seat, is used to store the headrest assembly 110; The headrest assembly 110 includes a headrest body and a connecting structure that connects the headrest body to the seat back. The drive module 120 is connected to the connection structure. The drive module 120 is used to drive the headrest assembly to be stored in the storage compartment or to extend out of the storage compartment. The control module 130 is used to respond to preset linkage commands or external trigger signals, detect the real-time height of the headrest body, and control the headrest assembly 110 to enter the storage compartment to complete the storage action or extend out of the storage compartment to complete the reset action.

[0022] The storage compartment refers to the hollow structure embedded in the seat back frame, which can be made of metal or high-strength plastic. Its internal space dimensions are at least adapted to the volume of the headrest body, allowing it to fully accommodate the headrest body when not in use. The connection structure of the headrest assembly enables linear displacement of the headrest body in the vertical direction. The drive module refers to the power output device and transmission mechanism, which can specifically use a stepper motor with a rack and pinion transmission assembly to convert rotational motion into the lifting and lowering action of the headrest assembly. The control module is the signal processing and execution unit, used to receive commands and provide feedback on the headrest position information to adjust the working state of the drive module.

[0023] Specifically, when the system receives the command to activate the double bed mode, the control module first obtains the current height data of the headrest through the position sensor. If the headrest is in the reset state, the control module sends a descent command to the drive module. The motor, through gear transmission, drives the connecting structure to move downward, causing the headrest to retract completely into the storage compartment inside the seat back. During this process, the position sensor continuously monitors the headrest displacement, automatically cutting off the motor power when the preset storage position is detected. In reverse operation, the control module drives the headrest to rise to its original usage height according to the reset command, and ensures positioning accuracy through sensor verification. The entire process requires no user intervention, and the headrest state switches synchronously with the seat scene mode.

[0024] Compared with existing technologies, this invention enables the headrest to be automatically stored inside the seat through a built-in storage compartment, eliminating the physical disassembly step and avoiding the inconvenience caused by manual operation; through the linkage of the drive module and the control module, the headrest can automatically extend and retract according to the needs of the scene, achieving intelligent linkage while ensuring the neatness of the interior space layout; and by utilizing the internal space of the seat back for storage, it improves the user experience and space utilization.

[0025] In some embodiments of the present invention, the drive module includes a motor and a transmission assembly connected to the headrest assembly; The motor is electrically connected to the control module, and the motor is used to drive the headrest assembly through the transmission components. The transmission assembly is connected to the output shaft of the motor and the connection structure of the headrest assembly, respectively. The transmission assembly is used to convert the rotational motion of the motor into the upward or downward motion of the headrest assembly. The motor can be a DC geared motor, whose output shaft is connected to the transmission assembly to transmit rotational power, serving as the power source for driving the headrest assembly. The transmission assembly refers to the mechanical structure that converts the motion into linear motion; it can be a rack and pinion mechanism or a ball screw mechanism. One end of the transmission assembly is connected to the motor output shaft to receive rotational power, and the other end is connected to the headrest assembly's connection structure. Through mechanical transmission, the rotational motion is converted into linear lifting motion, thereby achieving automated displacement control of the headrest assembly.

[0026] Through the above technical solution, this invention achieves automated lifting and lowering control of the headrest assembly within the storage compartment, eliminating the physical force required for traditional manual disassembly and solving the technical drawback of relying on manual operation in the headrest storage process. The cooperation between the transmission component and the motor enables the headrest to automatically complete storage or repositioning according to instructions, avoiding the problem of the headrest occupying interior space after disassembly, and providing an effective space optimization solution for various vehicle usage needs.

[0027] In some embodiments of the present invention, the control module includes a position sensor, a central processing unit, and a motor controller; A position sensor is used to detect the height of the headrest body in real time and output a height signal; The central processing unit is used to generate control instructions based on preset linkage instructions or external trigger signals; A motor controller is used to respond to control commands and control the direction and speed of the motor based on the altitude signal using proportional-integral-derivative (PID) control.

[0028] The position sensor is a detection device used to detect the vertical displacement of the headrest body, and can be implemented using a magnetostrictive linear sensor. This magnetostrictive linear sensor can be implemented using a component comprising a magnetostrictive waveguide wire, a magnetic ring, and a signal processing unit. The magnetic ring is fixed to the moving part of the headrest body, and the waveguide wire is arranged along the movement path of the headrest. The displacement is calculated by detecting the time difference of the pulse signal corresponding to the position of the magnetic ring. This sensor eliminates mechanical friction through a non-contact measurement method, avoiding wear errors caused by physical contact, thereby improving detection accuracy. An electrical signal is generated based on the correspondence between magnetic field changes and mechanical displacement, providing real-time position feedback for closed-loop control.

[0029] A central processing unit (CPU) is an integrated circuit capable of logic operations. It can be implemented using a microcontroller or embedded processor. It parses external instructions and generates motor drive strategies, enabling the generation and transmission of control commands. A motor controller is the power electronic device that drives the motor. It can be implemented using a combination of a high-side H-bridge circuit and a pulse-width modulation (PWM) module. It controls the motor's direction and speed by adjusting the current direction and duty cycle.

[0030] Specifically, upon receiving a preset command, a preset linkage command, or an external trigger signal, the position sensor continuously collects the height data of the headrest body and converts it into an electrical signal. The central processing unit determines, based on preset logic, whether to perform a retraction or reset action and generates a control command containing the target height parameter. After receiving the control command, the motor controller compares the target height with the actual height fed back by the position sensor in real time, calculates the current error value using a PID algorithm, and dynamically adjusts the motor's direction and speed. For example, during the retraction process, if the actual descent speed is lower than expected, the PID algorithm will automatically increase the output current to increase the motor torque and overcome the frictional resistance of the transmission mechanism; when approaching the target height, the algorithm automatically reduces the output current to avoid overshoot. This forms a closed-loop control circuit, ensuring that the headrest assembly can accurately reach the target position even under complex load conditions.

[0031] Through the above technical solution, this invention achieves automated control and dynamic adjustment of the headrest storage process. The entire process requires no manual contact with the headrest, simplifying the operation, significantly improving the convenience of seat mode switching, and eliminating the inefficiency caused by manual operation. The real-time feedback of headrest height from the position sensor, combined with dynamic compensation from the PID algorithm, ensures the motion accuracy of the headrest assembly under complex working conditions, avoiding the jamming or positioning inaccuracies caused by mechanical errors in traditional open-loop control.

[0032] In some embodiments of the present invention, the control module further includes an angle sensor, which is disposed at the connection between the seat back and the seat cushion. An angle sensor is used to detect the tilt angle of the seat back and output an angle signal; The central processing unit is also used to acquire angle signals and generate control commands when the seat back tilts to a preset angle or when the tilt angle remains unchanged. An angle sensor is a sensing device used to detect changes in the angle of mechanical parts. Specifically, it can be implemented using a rotary potentiometer or a Hall sensor. When placed at the connection between the seat back and the seat cushion, it can directly sense the rotational displacement of the hinge mechanism.

[0033] Compared to existing technologies, traditional seating systems require separate operation of the headrest storage device when adjusting the backrest angle, posing a risk of spatial interference due to asynchronous actions. This solution, through the coordinated control of an angle sensor and a central processor, enables an automatic linkage mechanism between the headrest storage action and changes in seat posture, eliminating the coordination problems caused by manual step-by-step operation.

[0034] The second aspect of this invention provides a control method for an intelligent linked storage system for automotive headrests, applicable to any of the intelligent linked storage systems for automotive headrests described in the first aspect above, such as... Figure 2As shown, the control method includes the following steps S210 and S220.

[0035] Step S210: Obtain a preset linkage command or external trigger signal.

[0036] Among them, preset linkage commands refer to mode switching commands generated by the vehicle control system. Specifically, this can be achieved through scene mode switching commands triggered by the in-vehicle central control screen, such as the command to activate the double bed mode. This feature is used to proactively identify user scenario needs and achieve automated response. External trigger signals refer to operation commands independent of the vehicle control system. Specifically, this can be achieved through physical buttons or wireless control signals from a mobile terminal APP. Trigger signals can be simply trigger signals for headrest storage, which expands the diversity of user operation methods.

[0037] Step S220: In response to a preset linkage command or an external trigger signal, detect the real-time height of the headrest body and control the headrest assembly to enter the storage compartment to complete the storage action or extend out of the storage compartment to complete the reset action.

[0038] Real-time height detection refers to the continuous acquisition of height data of the headrest body relative to the storage compartment through sensors. This feature provides position feedback for closed-loop control to avoid mechanical interference. The storage and reset actions refer to the vertical displacement process of the headrest assembly. The completion of the storage action means that the headrest body has been fully inserted into the storage compartment, and the completion of the reset action means that the headrest body is in the headrest body position in the driving state.

[0039] Specifically, the sensor can be a magnetostrictive linear sensor, which achieves real-time detection of the headrest height by periodically emitting current pulses and measuring the time difference of the stress wave return. The headrest height is calculated based on the following formula:

[0040] in, This indicates the headrest height, which is the distance between the magnetic ring at the bottom of the headrest and the fixed end of the sensor; This indicates the propagation speed of stress waves in the waveguide; It represents the time difference between the emission of the current pulse and the return of the stress wave.

[0041] Specifically, when a command to flatten the seat is detected, the central processing unit first obtains the headrest height data collected by the position sensor.

[0042] When the sensor uses a magnetostrictive linear sensor, such as Figure 3 As shown, the method for detecting the real-time height of the headrest body includes: Obtain the time difference using a preset sampling period ; Judging the time difference Is it constant? If so, it means the headrest is stationary and will continuously output fixed height data. If not, meaning the time difference changes in real time with height, it indicates that the headrest has moved. In this case, the headrest height is calculated using the above formula and the headrest height data is output.

[0043] Subsequently, the motor speed and steering parameters are calculated using a PID algorithm, driving the transmission mechanism to lower the headrest uniformly into the storage compartment. During this process, if the headrest is detected to be stuck or misaligned, the control module immediately pauses the operation and triggers an alarm. When a seat reset command is received, the system reverses the above process, extending the headrest from the storage compartment to a preset safe height. For external trigger signals, such as when the user manually triggers the storage operation via a vehicle button, the control module also executes the height detection and motion control process to ensure consistency in the action execution logic under different triggering methods.

[0044] The method of this invention enables the headrest to automatically extend and retract according to the needs of the scene, eliminating the physical disassembly steps and avoiding the inconvenience caused by manual operation; while realizing intelligent linkage, it ensures the neatness of the interior space layout; and it utilizes the internal space of the seat back for storage, improving user experience and space utilization.

[0045] In some embodiments of the present invention, the preset linkage commands include a seat flattening command and a seat reset command; When the preset linkage command is the seat flattening command, the headrest assembly is controlled to enter the storage compartment to complete the storage action; When the preset linkage command is the seat reset command, the headrest assembly extends from the storage compartment to complete the reset action.

[0046] The "seat recline command" refers to a mode switching request signal received through the vehicle control unit, such as entering a double bed mode. This signal can be generated via touch operation on the central control screen or voice command to trigger the seat to recline. The "seat reset command" refers to a mode exit signal generated through the same interaction method to restore the seat to the standard driving position.

[0047] It should be noted that the "flat seat" command means that the angle between the seat back and the seat cushion is greater than a preset angle threshold, such as 165 degrees, and does not mean that the seat back must be placed horizontally.

[0048] Through the above technical solution, the present invention realizes the intelligent linkage between the headrest storage action and the seat mode switching. When entering the double bed mode, it can automatically eliminate the influence of the headrest on the flatness of the seat surface and ensure the timely restoration of the headrest support function when exiting.

[0049] In some embodiments of the present invention, when the preset linkage command is a seat flattening command, the specific method for controlling the headrest assembly to enter the storage compartment to complete the storage action includes: Confirm that the seat back is stationary; When the seat back is stationary, the headrest assembly is controlled to retract into the storage compartment to avoid interference with the movement of the seat back. When the seat back is not stationary, a pause command is sent to the control module of the seat back, and the seat back is kept at the current angle until the headrest assembly enters the storage compartment to complete the storage action.

[0050] For example, the seat reclining command is generated by the system when the user triggers the "double bed mode" / "camping mode". At this time, the system can prioritize triggering the headrest command and put the headrest away. When the seat back is not stationary, the backrest motor pauses its operation and maintains the current angle until the headrest is in place signal feedback before it starts.

[0051] Next, combined Figure 4 The following is a detailed description of the headrest storage method of an intelligent linkage storage system for automotive headrests according to an embodiment of the present invention. In this embodiment, the control module is implemented through a microcontroller unit (MCU), and the motor is controlled through a high-side H-bridge drive circuit.

[0052] Upon receiving the headrest command, the MCU first calls the system's preset target height (i.e., the position when the headrest is fully retracted) and compares it with the current height fed back by the sensor in real time to calculate the height deviation. Based on this deviation, the PWM duty cycle is dynamically calculated using a PID algorithm, and then the control signal is transmitted to the high-side H-bridge drive circuit. The motor speed is changed by adjusting the output power. At the same time, the sensor continuously monitors the headrest position and feeds back to the MCU, forming a closed-loop control until the headrest reaches the target height and triggers the limit switch to stop, thus completing the retraction action. If the headrest does not reach the target height, i.e., the headrest is not fully retracted, the calculation is repeated.

[0053] In one embodiment of the present invention, when the preset linkage command is a seat reset command, the headrest assembly is controlled to extend from the storage compartment to complete the reset action, including: Confirm that the seat back has returned to the preset driving angle; When the seat backrest returns to the preset driving angle, the headrest assembly extends from the storage compartment to complete the reset action. When the seat back is not reset to the preset driving angle, the headrest assembly is kept in its current state.

[0054] Next, combined Figure 5 The headrest reset method of an intelligent linkage storage system for car headrests according to an embodiment of the present invention will be described in detail.

[0055] Figure 5This is a data flow diagram of the headrest reset function in an embodiment of the intelligent linkage storage system for car headrests according to the present invention; as shown below. Figure 5 As shown, when the user triggers "Exit Double Bed Mode," the central control system sends a reset command to the seat, and the seat prioritizes resetting the backrest. During the backrest reset process, the backrest angle is monitored in real time. The backrest module reads the angle data from the angle sensor in real time, provides angle feedback, and uses an adaptive PID algorithm to control the backrest motor to reset the seat back to the driver's default angle (e.g., 10°). Only after the backrest angle sensor confirms that it is in place is the headrest control module enabled and activated.

[0056] During the headrest reset process, the headrest control module acquires the headrest position information in real time through a magnetostrictive linear sensor. After calculating the deviation from the preset reset height, it uses an adaptive PID algorithm to dynamically adjust the PWM duty cycle and output it to the H-bridge drive circuit to achieve precise speed control of the motor. The system ensures smooth movement through a three-stage speed planning strategy (acceleration start-uniform speed operation-deceleration stop), while integrating position closed-loop feedback and limit switch dual confirmation to finally complete the automatic reset of the headrest. The entire process maintains strict timing synchronization with the backrest movement to avoid mechanical interference.

[0057] The above embodiments utilize magnetostrictive linear sensors to detect the headrest position, and combine adaptive PID control algorithms and H-bridge drive circuits to construct a closed-loop control system. A "backrest-headrest" timing decoupling strategy is adopted to ensure motion coordination, enabling one-click automatic storage and reset of the headrest. This completely solves the technical pain points of traditional headrests that rely on manual operation and occupy space, simplifying the operation steps from 5 steps to 1 button, improving space utilization by 100%, and providing an innovative space solution for smart cockpits.

[0058] This application also provides an electronic device, which includes a memory and a processor. The memory stores a computer program that is executed by the processor. When the computer program is executed by the processor, it causes the device equipped with the processor to perform the control method of the intelligent linkage storage system for car headrests as described in any of the above embodiments.

[0059] Next, refer to Figure 6 An example electronic device 100 is used to describe a control method for implementing an intelligent linkage storage system for car headrests according to embodiments of the present invention.

[0060] like Figure 6 As shown, the electronic device 100 includes a processor 110, a memory 120, and a communication interface 130. The processor 110, the memory 120, and the communication interface 130 can be interconnected and communicate via a communication bus 140 and / or other forms of connection mechanisms (not shown).

[0061] It should be noted that Figure 6 The components and structure of the electronic device 100 shown are merely exemplary and not limiting; the electronic device may also have other components and structures as needed.

[0062] Optionally, the communication interface 130 may also include a transmitter and / or a receiver.

[0063] The processor 110 may be a microcontroller unit (MCU), a central processing unit (CPU), a digital signal processor (DSP), a microcontroller and embedded device, or other processing units with data processing capabilities and / or instruction execution capabilities.

[0064] The memory 120 can be various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. The volatile memory may include, for example, random access memory (RAM), cache memory, synchronous dynamic random access memory (SDRAM), etc. The non-volatile memory may include, for example, read-only memory (ROM), hard disk, flash memory, etc. One or more computer program instructions may also be stored on the computer-readable storage medium, and the memory 120 can execute the program instructions to implement the control method of the intelligent linkage storage system for car headrests in the embodiments of the present invention described above.

[0065] This application also provides a storage medium storing a computer program that runs on a computer. When the computer program runs, it causes the computer to execute the control method of the intelligent linkage storage system for car headrests as described in any of the above embodiments.

[0066] Finally, it should be noted that the above technical solution is only one embodiment of the present invention.
