The invention provides a damping device for an elevator car and an elevator system. The damping device comprises a linkage piece and a plurality of fixing pieces, and the linkage piece is fixedly installed on a door body; 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. In response to opening of the door body, the door body pushes the linkage piece to move to the opening of the damping piece and extend into the first space; in response to closing of the door body, the door body pulls the linkage piece to be separated from the damping space; and when the upward or downward moving distance of the elevator car stopping at a certain flat layer relative to the preset stopping position reaches a preset distance, the linkage piece enters the second space and is in friction fit with the inner wall of the second space. The damping device has the advantages of being large in friction force, long in service life and capable of saving energy.

    本发明提供了一种用于电梯轿厢的阻尼装置和电梯系统,阻尼装置包括联动件和多个固定件,联动件固定安装于门体;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,其中,当电梯轿厢停靠在某一平层的预定停靠位置时,响应于门体打开,门体推动联动件移动至阻尼件的开口并伸入第一空间;响应于门体关闭,门体拉动联动件脱离阻尼空间;以及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,联动件进入第二空间且与第二空间的内壁摩擦配合。所述阻尼装置具有摩擦力大、寿命长和节约能源的优点。
