The invention relates to the technical field of seat vibration reduction, in particular to a multi-directional seat vibration reduction device and an engineering machinery seat, and the multi-directional seat vibration reduction device comprises a base with an open mounting cavity; the bearing plate is movably mounted in the mounting cavity; the horizontal vibration reduction assembly is used for extending in the horizontal direction, the first end of the horizontal vibration reduction assembly is fixed to the bearing plate, and the second end of the horizontal vibration reduction assembly is in sliding fit with the side wall of the mounting cavity; the vertical vibration reduction assembly comprises a top plate, a bottom plate and a vibration reduction assembly body, and the top plate is connected with the cushion backrest system through an adjustable guide rail; the vibration reduction assembly main body is mounted between the top plate and the bottom plate; and the pitching vibration reduction assembly is used for elastically connecting the bottom plate with the bearing plate, and the bottom plate can move in the pitching direction relative to the bearing plate. According to the invention, the transverse and longitudinal degrees of freedom of the lower end of the seat suspension are released, so that the vibration reduction performances in all directions are not easy to influence each other, and the purpose of remarkably improving the vibration comfort of the engineering machinery is achieved.
本发明涉及座椅减振技术领域,具体涉及一种座椅多向减振装置及工程机械座椅,其包括:底座,上形成敞口的安装腔;承载板,可移动地安装于所述安装腔内;水平减振组件,用于沿水平方向延伸设置,第一端部固定于所述承载板上,第二端部与所述安装腔侧壁滑动配合;垂向减振组件,包括顶板、底板以及减振组件主体,所述顶板通过可调节导轨与坐垫靠背系统连接;所述减振组件主体,安装于所述顶板和底板之间;俯仰减振组件,用于将所述底板与所述承载板弹性连接,且所述底板能够相对所述承载板在俯仰方向上活动。本发明通过使座椅悬挂下端横向、纵向自由度得到释放,以使得各方向的减振性能不易互相影响,从而实现显著提升工程机械振动舒适性的目的。
