The invention discloses an emergency evacuation door which comprises a door leaf, a connecting rod connecting the door leaf and the bottom of a vehicle body and a turnover pedal rotationally connected with the middle of the inner side of the door leaf, the connecting rod rotates relative to the door leaf to drive the door leaf to be away from the vehicle body and be lowered, and a first gear is arranged at the end, connected with the bottom of the door leaf, of the connecting rod. The inner side wall of the door leaf is connected with the transmission shaft, the second gear, the first gear and the second gear are meshed with the two ends of the transmission shaft respectively, the second gear is connected with the turnover pedal through the differential part, and the first gear drives the turnover pedal to cross the interface through the transmission shaft, the second gear and the differential part with the vertical transition state of the turnover pedal and the door leaf as the interface. And a damper is arranged between the door leaf and the turnover pedal. According to the invention, the gears are all mounted on the door leaf, transmission can be realized between the gears through the transmission shaft, the transmission structure is simplified, meshing impact is reduced, debugging and maintenance are convenient, and when the turnover pedal is driven by self weight to move, the damper can reduce the impact at the end of flattening or folding.

    本发明公开了一种紧急疏散门,包括门页、连接门页和车体底部的连杆、以及与门页里侧中部转动连接的翻转踏板,连杆相对门页转动,以驱动门页远离车体并下放,所述连杆和门页底部连接的一端设有第一齿轮,门页内部侧壁连接传动轴、第二齿轮,第一齿轮、第二齿轮分别和传动轴两端啮合,第二齿轮通过差动件和翻转踏板连接,以翻转踏板和门页垂直的过渡态为界面,第一齿轮通过传动轴、第二齿轮、差动件驱动翻转踏板越过界面,所述门页和翻转踏板之间设有与阻尼器。本发明中,齿轮均安装在门页上,齿轮间通过传动轴即可实现传动,简化了传动结构,减小了啮合冲击,方便调试维护,翻转踏板由自重驱动的运动时,阻尼器能减小展平或者折叠末期瞬间的冲击。
