The invention provides a damping device for an elevator car. The damping device comprises a movable part and a plurality of fixed parts, and the movable part is movably arranged on the elevator car; the multiple fixing pieces are arranged at multiple flat layers of an elevator shaft correspondingly, each fixing piece is an elastic damping piece, each damping piece is provided with a damping space with at least one side open, the damping space comprises a first space and a second space communicated with the first space, and when an elevator car stops at a preset stopping position of a certain flat layer, the second space is communicated with the first space. The moving part moves to the opening of the damping part and extends into the first space, and when the distance of upward or downward movement of the elevator car stopping at a certain flat layer relative to a preset stopping position reaches a preset distance, the moving part enters the second space and is in friction fit with the inner wall of the second space; therefore, vertical shaking of the elevator car when passengers enter and exit is reduced. The damping device has the advantages of being large in friction force and long in service life.

    本发明提供了一种用于电梯轿厢的阻尼装置,包括移动件和多个固定件,移动件可移动地设于电梯轿厢;多个固定件分别设于电梯井道的多个平层处,每个固定件为具有弹性的阻尼件,每个阻尼件具有至少一侧开口的阻尼空间,阻尼空间包括第一空间和与第一空间连通的第二空间,当电梯轿厢停靠在某一平层的预定停靠位置时,移动件移动至阻尼件的开口并伸入第一空间,并且当停靠在某一平层的电梯轿厢相对于预定停靠位置向上或向下移动的距离达到预定距离时,移动件进入第二空间且与第二空间的内壁摩擦配合,以减小电梯轿厢在乘客进出时的上下晃动。所述阻尼装置具有摩擦力大、寿命长的优点。
