Escape structure of elevator

The invention discloses an escape structure of an elevator. The escape structure of the elevator comprises an elevator car top, an elevator car safety window access formed in the elevator car top, and a ceiling. The ceiling comprises at least one slidable ceiling mobile plate assembly. The overlapping area of the area of the elevator car safety window access and the protection area, on the elevator car top, of a ceiling access formed in the ceiling after the ceiling mobile plate assemblies slide is vertically projected in the space between the elevator car top and the ceiling so as to form a channel space for connecting the internal space of an elevator car with the external space of the elevator car top in a communicated mode. The escape structure of the elevator has an effective safety escape channel space, and no obstructions exit in the space; the escape channel is opened and closed conveniently and rapidly; and the ceiling is convenient and rapid to install and can be installed in the elevator car due to the modular ceiling structure.
