Problems solved by technology

The traditional passive seat suspension mainly includes the backrest type and the lower scissor type. The structure is relatively simple, but the natural frequency is high and the natural frequency is fixed, so the comfort is not good; the active seat has good comfort due to the adjustable stiffness and damping , but the structure is more complicated, the cost is higher, and the energy consumption is more; the performance of the semi-active seat is between the traditional passive seat and the active seat, but the structure is more complicated than the traditional passive seat, and the performance is not as good as the active seat

Abstract

The invention provides an adjustable high-vibration-isolation-performance automobile seat suspension structure and belongs to the field of vehicle seats. The structure comprises a lower installation board, an upper installation board, a height adjusting component, a lower movable board, a working point adjusting component, an upper movable board, a quasi-zero rigidity component and an installationsupport. The height adjusting component can make a seat adapting to a driver and a passenger in different heights and is arranged on the lower installation board so as to make the lower movable boardvertically ascend and descend. The working point adjusting component can make the seat adapting to the driver and the passenger in different weights and is arranged on the lower movable board so as to make the upper movable board vertically ascend and descend. The installation support is fixed to the upper installation board. The quasi-zero rigidity component is composed of a positive-rigidity spring and a negative-rigidity mechanism, the two ends of the positive-rigidity spring act on the upper movable board and the installation support, and the two ends of the negative-rigidity mechanism are connected to the lower movable board and the installation support. The quasi-zero rigidity characteristic is achieved near a set working point, low-frequency, medium-frequency and high-frequency vibration can be well isolated, and the structure can adapt to the driver and the passenger in different weights and heights.

Description

technical field [0001] The invention belongs to the technical field of vehicle seats, and is suitable for vibration isolation of seats for drivers and occupants such as passenger cars and commercial vehicles, and in particular relates to an adjustable high-vibration isolation performance car seat suspension structure. Background technique [0002] Car seats mainly include passive seats, active seats, and semi-active seats. The traditional passive seat suspension mainly includes the backrest type and the lower scissor type. The structure is relatively simple, but the natural frequency is high and the natural frequency is fixed, so the comfort is not good; the active seat has good comfort due to the adjustable stiffness and damping , but the structure is more complicated, the cost is higher, and the energy consumption is more; the performance of the semi-active seat is between the traditional passive seat and the active seat, but the structure is more complicated than the trad...
