Active posture compensation seat and anti-impact assembly thereof

An anti-impact assembly, the anti-impact assembly being configured to connect to a seat body of a vehicle, the anti-impact assembly comprising:

• a bottom plate;
• a pitch base plate, arranged opposite to the bottom plate;
• a motor, respectively connected to the bottom plate and the pitch base plate, and the motor being configured to drive the pitch base plate to move;
• a radar system, configured to detect a first data of the vehicle and an obstacle ahead, the first data comprising one or any combination of a relative velocity, a distance and an angle change;
• a vision system, comprising a camera and a processor, the camera being configured to acquire a multi-dimensional space depth information of the vehicle, and the processor being configured to estimate a second data related to a collision with the obstacle ahead, the second data comprising a collision time and/or a collision angle;
• and
• a safety system, electrically connected to the motor, the safety system comprising a sensor and a controller;
• and the controller being configured to adjust a posture of the seat body according to the first data, the second data and a data of the sensor;
• wherein:
• the controller is configured to drive the pitch base plate to move through the motor, thereby adjusting the seat body to a first posture when the vehicle runs normally, and in the first posture, a first pitch angle is formed between a bottom of the seat body and the bottom plate;
• the controller is configured to drive the pitch base plate to move through the motor, thereby adjusting the seat body from the first posture to a second posture when the vehicle is detected to be under emergency braking and/or there is a collision risk, and in the second posture, a second pitch angle is formed between the bottom of the seat body and the bottom plate, the first pitch angle is greater than the second pitch angle.
