The invention discloses an elevator car vibration reduction structure capable of automatically adjusting damping, and belongs to the technical field of elevator equipment. The device is composed of a piston rod, a hydraulic cylinder fastening nut, a hydraulic cylinder fastening bolt, a piston, an upper cylinder cover, a lower cylinder cover, a hydraulic cylinder body, a piston hole baffle driving gear I, a gear bearing seat connecting plate, a gear bearing seat, a piston hole baffle driving gear II, a piston hole baffle corner adjusting gear and a piston hole baffle corner adjusting rack. A shock absorber pushes a piston to do reciprocating motion through a piston rod, the piston drives a gear bearing seat connecting plate and a piston hole baffle corner adjusting gear to move up and down, and the piston hole baffle corner adjusting gear is meshed with a piston hole baffle corner adjusting rack to drive a piston hole baffle driving gear II to rotate. The gear shaft and the piston hole baffle are further driven to rotate, the piston hole baffle blocks an oil hole in the piston when rotating, automatic adjustment of damping is achieved through reciprocating motion of the piston rod, the problem of vibration generated when the lift car is subjected to external loads is solved, and riding comfort is enhanced.

    一种自动调节阻尼的电梯轿厢减振结构,属电梯设备技术领域,由活塞杆、液压缸紧定螺母、液压缸紧定螺栓、活塞、上缸盖、下缸盖、液压缸体、活塞孔挡板驱动齿轮Ⅰ、齿轮轴承座连接板、齿轮轴承座、活塞孔挡板驱动齿轮Ⅱ、活塞孔挡板转角调节齿轮、活塞孔挡板转角调节齿条组成;减振器通过活塞杆推动活塞做往复运动,活塞带动齿轮轴承座连接板及活塞孔挡板转角调节齿轮上下移动,活塞孔挡板转角调节齿轮与活塞孔挡板转角调节齿条啮合,带动活塞孔挡板驱动齿轮Ⅱ转动,进一步驱动齿轮轴与活塞塞孔挡板旋转,活塞孔挡板在旋转时挡住活塞上的油孔,通过活塞杆的往复移动实现阻尼的自动调整,解决轿厢受外部载荷所产生的振动问题,增强乘坐舒适性。
