Abstract
The utility model provides a three-dimensional vibration-attenuating seat used for an engineering vehicle and relates to a vehicle seat. The utility model aims to solve a problem that a prior engineering vehicle seat mechanism hurts health of a driver comparatively severely since the prior engineering vehicle seat mechanism can realize vertical vibration attenuation only but cannot realize three-dimensional vibration attenuation. According to the utility model, a fixed support and a movable support are composed of 3 main support piece, 17 connection rods and 6 ball hinged supports respectively. Three groups of magneto-rheological damper driving branched chains are connected between the fixed support and the movable support in parallel, wherein each of the groups includes two branched chains attenuating vibration and impact from all directions of the automobile seat. The three-dimensional vibration-attenuating seat used for the engineering vehicle provided by the utility model has a three-dimensional vibration-attenuating effect. Since an orthogonal arrangement is adopted, decoupling of the seat can be realized freely and the riding comfort of the vehicle can be improved. Besides, the three groups of the magneto-rheological damper driving branched chains are disposed in a space defined by the movable support and the fixed support, so that the three-dimensional vibration-attenuating seat used for the engineering vehicle is compact in structure and low in space occupancy, and can meet strict requirements for vehicle seat space.
