In the event of an accident or failure of the elevator, the car emergency exit is used for rescuing and evacuating passengers.

[0003] Application No. 2021229985420 discloses a detachable and openable escape starlight ceiling, comprising a supporting device, a rotating device is symmetrically installed inside the supporting device, and a wind deflector is fixedly installed at the top of the supporting device. The supporting device comprises a limiting nut, a supporting screw rod, an isolation cover plate, a plastic fillet, a supporting panel, a positioning hole, a supporting longitudinal beam, a side plate and a supporting cross beam. The supporting longitudinal beam is fixedly installed between the supporting cross beams, the side plate is fixedly installed on both sides of the supporting cross beam, the positioning hole is symmetrically formed in the bottom of the side end of the side plate close to the supporting cross beam, the isolation cover plate is fixedly connected on both sides of the supporting panel, and the supporting panel is fixedly connected to the bottom end of the supporting cross beam.

[0004] The problems of the prior art are as follows: the other end of the hinge is fixedly connected to the bottom end of the supporting panel, the cover plate can be flipped downward at an angle, which facilitates personnel to escape from the inside of the supporting device to the outside in an emergency, but personnel cannot climb from the car to the roof of the car. In addition, during rescue, even if the rescue personnel come from the bottom of the elevator shaft to the top of the car, they cannot provide much help to the personnel in the car, and can only use an external lifting rope to lift the passengers out of the car. Since the safety window is arranged on the top of the car, it can only be pulled by the rescue personnel, which brings great obstacles to the rescue work. SUMMARY

[0005] In view of the above problems existing in the prior art, the present application provides an emergency escape device and an elevator thereof, which comprises a flip box and a cover body hinged together, and a hydraulic rod connected between the cover body and the flip box.
