Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0051] The object of the present invention is to provide a seat suspension with active and semi-active mixed control. By setting a scissor bracket between the fixed base plate and the seat mounting plate, the actuator is connected with the scissor bracket, and the active suspension is adopted by the control device. Controlled or semi-active control modes control the movement of the actuators to dampen vehicle vibrations while reducing active control energy consum...

Abstract

The invention discloses a vehicle and a seat suspension based on active and semi-active mixed control. The seat suspension comprises a fixing baseplate, a seat mounting plate, a scissor-type support frame, an actuator and a controller. The fixing baseplate is arranged on a vehicle chassis. A vehicle seat is mounted on the seat mounting plate. The scissor-type support frame is arranged between thefixing baseplate and the seat mounting plate. After the fixing baseplate is vibrated and / or the vehicle seat is loaded with mass, the scissor-type support frame can extend and retract to change the vertical distance between the fixing baseplate and the seat mounting plate. The actuator is used for driving the scissor-type support frame to move. The controller is used for controlling the actuator to move through active control or semi-active control so as to damp the vehicle. The seat suspension has the advantages that the scissor-type support frame is arranged between the fixing baseplate andthe seat mounting plate, the actuator is connected with the scissor-type support frame, the controller controls the actuator to move through active control or semi-active control to damp the vehicle,and power consumption of the active control can be reduced.

Description

technical field [0001] The invention relates to the technical field of motor vehicles, in particular to an active and semi-active hybrid control seat suspension and a vehicle. Background technique [0002] Drivers of heavy vehicles are exposed to high-intensity vibration for a long time, which will seriously affect their health and cause shoulder discomfort, back pain, etc., especially heavy engineering vehicles, agricultural vehicles, mining vehicles and military vehicles. The uneven road surface on which the vehicle is driven causes severe vibration, which seriously affects the ride comfort, safety and handling convenience of the occupants. The performance of the seat suspension will directly affect the comfort of the driver. [0003] Currently, there are mainly three types of seat suspensions in use: passive seat suspensions, semi-active seat suspensions and active seat suspensions. Active seat suspension can achieve the best vibration reduction effect, but the high ene...
