Self-adaptive adjusting active vibration-reducing auto seat

Abstract

The invention relates to automobile parts, in particular to a self-adaptive adjusting active vibration-reducing auto seat. The seat is installed in a carriage of an automobile, and comprises a seat body, four air-pressure actuators, a magnetic actuator, a main gyroscope sensor, a main vibration accelerated speed sensor, an auxiliary gyroscope sensor, an auxiliary vibration accelerated speed sensor, four air supplying and pressure regulating devices and an electronic control unit. According to the seat, the riding comfort of the automobile and the accuracy of posture control of the seat are improved; a self-adaptive posture adjusting function of the seat is achieved by the gyroscope sensors, the electronic control unit, the air supplying and pressure regulating devices and the air-pressure actuators, an active vibration-reducing function of the seat is achieved by the vibration accelerated speed sensor, the electronic control unit and the magnetic actuator, and the two functions can work simultaneously and separately to form a whole in structure without affecting each other on functions, so that the reliability of a system is improved; the structure is compact, the stability is good, the cost is low, and motion interference is avoided.

Description

1. Technical field [0001] The invention relates to automobile parts, in particular to an adaptively adjusted automobile active damping seat. 2. Background technology [0002] The car seat is an important part of the interior of the vehicle. Its main function is to support the mass of the occupant, ease and attenuate the shock and vibration transmitted from the body, provide the driver with good working conditions, and create comfortable and safe riding conditions for the passengers. . During the operation of the car, when the body rolls due to factors such as road inclination or car steering, the direction of the human body on the seat will also change, and the frequency is relatively low; When vibrating, the position of the human body on the seat will also change, and its frequency is relatively high. The low-frequency direction changes and high-frequency position changes of the seat and human body greatly reduce the comfort of the car, and even cause a series of motion s...

AI Technical Summary

Problems solved by technology

However, there is only one acceleration sensor installed on the floor of the carriage to monitor the acceleration signal in the system, and the direction angle signal of the vehicle body and the seat and the acceleration signal of the seat are not monitored. On the one hand, the direction angle of the vehicle body and the seat cannot be accurately measured. On the one hand, feedback control cannot be realized, so the control accuracy is limited; the telescopic mechanism is connected to the seat through a spherical pair and a slider, the structure is not compact, and the cost is high; When the telescopic mechanism fails, the two functions cannot be realized, and the reliability is low; the support stability of the seat with three telescopic mechanisms is not as good as that of the four-point support method
