The automatic unfolding evacuation ramp comprises a folding ramp assembly, a supporting leg assembly on the bottom face of the ramp assembly and an extension pedal hinged to the front end of the ramp assembly, and when the ramp assembly is unfolded, the supporting leg assembly is unfolded and stretches out; a first torsional spring is arranged between the ramp assembly and the extending pedal, a lock hook assembly and a lock stop assembly which are rotationally connected are arranged on the two sides of the ramp assembly respectively, the lock hook assembly can hook the extending pedal in a folded state, and a second torsional spring is arranged between the lock stop assembly and the ramp assembly. The bottom of the stopper assembly extends to the side, extending out of the ramp assembly, of the supporting leg assembly, when the ramp assembly is folded, the supporting leg assembly is folded, the ramp assembly pushes the latch hook to be separated from the extension pedal, and the stopper assembly is released by the supporting leg assembly and replaces the latch hook assembly to hook the extension pedal. According to the scheme, rapid unfolding and barrier-free evacuation can be achieved at the same time.
本发明公开了一种自动展开疏散坡道,包括折叠式坡道组件、坡道组件底面的支腿组件,以及与坡道组件前端铰接的延伸踏板,坡道组件展开时,支腿组件展开伸出;所述坡道组件和延伸踏板之间设有第一扭簧,所述坡道组件两侧分别设有转动连接的锁钩组件、锁挡组件,锁钩组件能够钩住折叠状态的延伸踏板,所述锁挡组件与坡道组件之间设有第二扭簧,锁挡组件底部延伸至支腿组件伸出坡道组件的一侧,坡道组件折叠时,支腿组件折叠,坡道组件推动锁钩脱离延伸踏板,锁档组件被支腿组件释放,接替锁钩组件钩住延伸踏板。本方案可以同时实现快速展开和无障碍疏散。
