The invention relates to the technical field of elevator car protection, in particular to a protective air cushion for the interior of a car during elevator falling, which comprises a car body, an elastic support, a supporting plate, a bottom plate, a protective air bag, a top plate, a traction frame, a fixing plate, a transmission case, an unfolding mechanism, an exhaust mechanism and a clamping mechanism. The unfolding of the protective air bag is realized through the unfolding mechanism, upward pressure is prevented from being applied to legs of a passenger in the unfolding process of part of the air bag, so that feet of part of the passenger are prevented from being easily injured, air in part of the air bag can be slowly exhausted through parts such as exhaust holes through the exhaust mechanism, and the safety of the passenger is improved. According to the device, the expanded air cushion is prevented from occupying the activity space of passengers, clamping and fixing of the protection air bag are achieved through the clamping mechanism, part of the device can assemble, disassemble and fix the protection air cushion, the protection air cushion can be conveniently maintained, and the protection performance, safety and convenience of the device are improved.
本发明涉及电梯轿厢防护技术领域,具体为一种电梯坠落时轿厢内部用防护气垫,包括厢体、弹性支座、托板、底板、防护气囊、顶板、牵引框、固定板、传动箱、展开机构、排气机构、夹持机构。本发明通过展开机构实现了防护气囊的展开,避免部分气囊在展开的过程中会对乘员腿部施加向上压力,从而避免了部分乘员的脚部容易受伤,通过排气机构使得部分气囊内部的气体可以通过排气孔等部件缓慢排出,避免了膨胀后的气垫挤占乘员的活动空间,通过夹持机构实现了防护气囊的夹持固定,使得部分装置可以对防护气垫进行装卸固定,便于对防护气垫进行维护,提升了装置的防护性、安全性和便捷性。
