[0038] In one embodiment, Figure 1 A structural schematic diagram of an automotive seat system is provided, such as... Figure 1 As shown, the automotive seat system includes: a seat 1, which includes a headrest 11, a backrest 12, and a seat cushion 13; the automotive seat system also includes a sensor module 2, an airbag system 3, and a control module (not shown in the figure), which are connected in sequence; wherein, the sensor module 2 includes an acceleration sensor and a pressure sensor, and at least two acceleration sensors and at least two pressure sensors are distributed inside the seat 1 (for example, located at least two positions in the headrest 11, backrest 12, and seat cushion 13); the airbag system 3 includes an airbag 31 and a pneumatic actuator (not shown in the figure), at least two airbags 31 are distributed inside the seat 1, and the airbags 31 are connected to the pneumatic actuator, which is used to inflate or deflate the airbags 31; the sensor module 2 and the control module are respectively connected to an on-board electronic terminal, the sensor module 2 is used to send the collected sensing data to the on-board electronic terminal, and the control module is used to receive the control signal generated by the on-board electronic terminal and output the control signal to the pneumatic actuator.

[0039] In this embodiment, a pressure sensor is used to collect pressure data on the seat, and an acceleration sensor is used to collect acceleration change data when the seat vibrates. The pressure sensor and acceleration sensor send the collected sensor data to the vehicle electronic terminal, which processes the sensor data and generates a control signal. The control module obtains the control signal from the vehicle electronic terminal and sends the control signal to the pneumatic actuator to inflate or deflate the airbag 31, thereby adjusting the seat 1.

[0040] When a user sits on seat 1, pressure is applied to seat 1. When the car suddenly changes speed, the acceleration of seat 1 changes. Therefore, pressure data and acceleration change data can reflect the user's body shape and driving condition to a certain extent. Sensor module 2 collects sensing data to perceive the pressure distribution of the seat and the current driving condition. The built-in algorithm of the vehicle electronic terminal can process the sensing data, analyze the user's body shape information and current driving condition based on the pressure distribution of seat 1, and then generate corresponding control signals. The control module receives the control signal and sends it to the corresponding pneumatic actuator to control the corresponding airbag 31 to inflate or deflate. Specifically, sensor module 2 sends the collected pressure and acceleration data to the vehicle electronic terminal for analysis. Through algorithms (such as fuzzy PID control), it judges changes in occupant posture or environmental abnormalities (such as sudden braking). The vehicle electronic terminal outputs control signals to the control module, and the control module forwards the control signals to the corresponding airbag system 3. For example, when sudden braking (acceleration > 0.5g) is detected, the airbag in area 11 of the headrest is inflated to provide neck support; when the pressure sensor senses a shift in the occupant's sitting posture, the airbag in area 12 of the backrest is inflated to correct the posture.

[0041] Through this embodiment, the shape and support of the seat 1 can be adaptively adjusted to achieve intelligent adjustment of seat comfort, which helps to reduce fatigue during long-distance driving or riding.

[0042] In one embodiment, Figure 2 A schematic diagram of the structure of an airbag system 3 is provided, as follows: Figure 2 As shown, in this airbag system 3, the pneumatic actuator includes: an air pump 32, multiple valves 33, and multiple air pipes 34; wherein each airbag 31 is connected to the air pump 32 through an independent valve 33 and air pipe 34, the valve 33 is installed on the air pipe 34 and is close to the air inlet of the airbag 31, and the air pump 32 and valves 33 are respectively connected to the control module. The figure is for illustrative purposes only; in some embodiments, there may be more... Figure 2 Show more or fewer components.

[0043] In this embodiment, valve 33 can be a solenoid valve, and air pump 32 can be an electric pump. Multiple independently adjustable airbags 31 are used, and the inflation and deflation of the airbags 31 are controlled by the air pump and valve, enabling the seat's support shape to change within seconds. Specifically, refer to... Figure 1 The seat 1 includes a headrest 11, a backrest 12, and a seat cushion 13. An acceleration sensor and a pressure sensor are respectively distributed in at least one part of the headrest 11, backrest 12, and seat cushion 13; airbags are distributed in at least one part of the headrest 11, backrest 12, and seat cushion 13. Therefore, when it is necessary to change the shape of a certain position of the seat 1, only the airbag 31 at that corresponding position needs to be adjusted, thus flexibly and precisely changing the shape of that position of the seat 1.

[0044] In one embodiment, the air pump 32 is located below the seat 1 or on the side of the seat, so that the air pump 32 is close to the airbag 31, shortening the length of the air tube 34 and improving the inflation and deflation efficiency.

[0045] In one embodiment, the headrest 11 can be adjusted in height, the backrest 12 can be adjusted in tilt angle, and combined with the adjustment of the airbag 31 in the seat 1, the flexibility of seat comfort adjustment is further increased.

Figure 3 As shown, control module 4 includes at least two of the following control units: head control unit 41, shoulder control unit 42, waist control unit 43, hip control unit 44, and leg control unit 45.

Figure 4 As shown, the head control unit 41 is disposed inside the headrest 11, and the head control unit 41 is connected to the pneumatic actuator corresponding to the part of the headrest 11. Specifically, the head control unit 41 is connected to the valve of the headrest 11, and the head control unit 41 can adjust the airbag of the headrest 11 by outputting a control signal to the valve, thereby adjusting the shape of the headrest 11.

[0048] A shoulder control unit 42 is disposed in the upper half of the backrest 12, and is connected to a pneumatic actuator corresponding to the upper half of the backrest 12. Specifically, the shoulder control unit 42 is connected to a valve in the upper half of the backrest 12, and can adjust the airbag in the upper half of the backrest 12 by outputting a control signal to the valve, thereby adjusting the shape of the upper half of the backrest 12.

[0049] A lumbar control unit 43 is located in the lower half of the backrest 12 and is connected to a pneumatic actuator corresponding to the lower half of the backrest 12. Specifically, the lumbar control unit 43 is connected to a valve in the lower half of the backrest 12, and can output a control signal to the valve to adjust the airbag in the lower half of the backrest 12, thereby adjusting the shape of the lower half of the backrest 12.

[0050] A hip control unit 44 is located in the front half of the seat cushion 13, and is connected to a pneumatic actuator corresponding to the front half of the seat cushion 13. Specifically, the hip control unit 44 is connected to a valve in the front half of the seat cushion 13, and can adjust the shape of the front half of the seat cushion 13 by outputting a control signal to the valve.

[0051] A leg control unit 45 is located in the rear half of the seat cushion 13, and is connected to a pneumatic actuator corresponding to the rear half of the seat cushion 13. Specifically, the leg control unit 45 is connected to a valve in the rear half of the seat cushion 13, and can adjust the airbag in the rear half of the seat cushion 13 by outputting a control signal to the valve, thereby adjusting the shape of the rear half of the seat cushion 13.

[0052] In this embodiment, by setting different control units at multiple positions of the seat, when it is necessary to change the shape of a certain position of the seat 1, the airbag at the corresponding position can be adjusted by the control unit at that position, so that the shape of that position in the seat 1 can be changed flexibly and accurately.
