[0002] With the sustained rapid economic development, the urban population has been increasing year by year, and buildings in cities are getting taller and taller.

[0003] As the only facility for transferring people living or working in buildings, elevators are closely related to the life safety of people living in cities. However, in the event of fire or other natural disasters, there are frequent cases of people being trapped in elevators and dying because rescuers are not timely or the situation on the ground is too complicated to carry out rescue operations.

[0004] Currently, self-rescue can be achieved through rope ladders, climbing ladders, and escape doors. However, rope ladders and climbing ladders require a high level of physical strength from the trapped personnel and are not suitable for the elderly, children, or people with mobility impairments. If the trapped time is long, there will be a lack of oxygen in the car. Utility Model Content
