[0028] It can be understood that the seat slide, seat body and controller constitute the main structure of the seat adjustment system. The seat slide is located below the seat body, so that the seat body can move on the predetermined track of the seat slide, and the controller is electrically connected to the seat body, so that the controller can control the movement of the seat body. The first slide, the second slide, the first drive mechanism and the displacement sensor constitute the main structure of the seat slide. The first slide and the second slide can move relative to each other, so that the seat body can move. The first drive mechanism can drive the first slide and the second slide to move relative to each other, so that the seat body can perform corresponding actions. The displacement sensor can detect the position of the seat body. The seat cushion, the backrest, the second drive mechanism and the pressure sensor constitute the main structure of the seat body. The seat cushion and the backrest can provide a sitting position for the driver and passengers. , and the backrest can be rotated relative to the seat cushion, so that the driver and the passenger can select the direction of the seat body according to the actual situation. The second drive mechanism is electrically connected to the backrest, so that the second drive mechanism can drive the backrest to rotate. The pressure sensor can detect the pressure of the seat cushion and the backrest on the human body. The first drive mechanism, the second drive mechanism, the displacement sensor and the pressure sensor are all electrically connected to the controller, so that the signals detected by the displacement sensor and the pressure sensor can be transmitted to the controller. After calculation, the controller provides different preset seat modes for passengers of different heights, weights and ages, and then transmits the preset seat mode signal to the first drive structure and the second drive structure, so that the first slide rail can move relative to the second slide rail and the backrest can rotate, so that the seat can quickly reach a comfortable position for the human body and be adjusted intelligently.

The second drive mechanism can drive the backrest to rotate relative to the seat cushion, so as to meet the front and rear space requirements in the zero gravity posture.

[0029] Therefore, by arranging a first drive mechanism and a displacement sensor on the seat slide rail, and arranging a second drive mechanism and a pressure sensor on the seat body, such an arrangement can enable the displacement sensor to detect the position of the seat, and the pressure sensor to detect the pressure exerted on the seat, and both the first drive mechanism and the second drive mechanism are connected to the controller, so that the controller can control the first drive mechanism to drive the movement of the seat slide rail, and control the second drive mechanism to drive the rotation of the seat body, and thus the seat can be intelligently adjusted according to the preset seat mode.

[0030] There are multiple pressure sensors, which are respectively arranged on the surface of the backrest and the surface of the seat cushion. That is to say, multiple pressure sensors are respectively arranged in the backrest and the seat cushion. When the driver and passenger sit in the seat body, multiple pressure sensors detect the pressure on the back and buttocks of the driver and passenger, so that the signal detected by the pressure sensor can be transmitted to the controller. After calculation, the controller provides different preset seat modes for passengers of different heights, weights and ages, so that the seat can quickly reach a comfortable position for the human body and be adjusted intelligently.

[0031] In addition, the seat body also includes: a third drive mechanism, which is connected to the seat cushion in a transmission manner to drive the seat cushion and the backrest to tilt relative to the first slide rail, and the third drive mechanism is electrically connected to the controller.
