The invention relates to the technical field of elevator anti-collision, and discloses a passenger elevator lower end anti-collision system which comprises a bottom plate, a second cushioning mechanism is arranged at the top of the bottom plate and used for conducting second-time buffering and damping on the bottom of an elevator, the second cushioning mechanism comprises a fixing plate, and a damper is fixedly installed on the top wall of the fixing plate and used for conducting second-time damping on the bottom of the elevator. And a top plate and a third cushioning mechanism are fixedly mounted at the output end of the damper, the third cushioning mechanism is arranged on the top wall of the fixing plate and used for conducting third-time cushioning and damping on the bottom of the elevator, and the third cushioning mechanism comprises a first extrusion block. Through direct cooperation of a first cushioning mechanism, a second cushioning mechanism, a third cushioning mechanism and an inflatable airbag, the effect of multi-stage damping is achieved, the influence of impact generated by falling on equipment and personnel is reduced, then activated carbon particles stored in side plates are extruded out, toxic gas in an elevator shaft is adsorbed, and the safety of the elevator shaft is improved. And toxic gas entering the lift car through bottom gaps is reduced, and the influence on passengers is reduced.

    本申请涉及电梯防撞技术领域,公开了一种客运电梯下端防撞系统,包括底板,所述底板顶部设置有第二缓震机构,用于对电梯底部进行第二次缓冲减震,所述第二缓震机构包括固定板,所述固定板顶壁固定安装有阻尼器,所述阻尼器的输出端固定安装有顶板,第三缓震机构,其设置在固定板的顶壁,用于对电梯底部进行第三次缓冲减震,所述第三缓震机构包括挤压块一。通过第一缓震机构,第二缓震机构,第三缓震机构和充气气囊直接的配合,达到了分级多次减震的效果,减小了坠落产生的冲击对设备和人员的影响,再通过将侧板内部存放的活性炭颗粒挤出,对电梯井内部的有毒气体吸附,减少毒气通过底部缝隙进入轿厢内部,降低对乘客造成的影响。
