[0001] The utility model relates to the technical field of elevators, in particular to a car roof with a waterproof safety window. Background Art

[0002] In today's society, urbanization is developing rapidly, and many high-rise buildings are constantly being built. In high-rise buildings, elevators are an indispensable means of transportation, which facilitates people to go up and down the stairs and transport goods. Elevators are used frequently and some malfunctions are inevitable. If an elevator malfunctions while in use, it will trap the passengers. Therefore, it is very necessary to set up an escape window on the elevator.

[0003] However, the actual situation faced by elevator shafts is more complicated. When escaping from safety windows, since the electrical equipment on the elevator is not powered off or is suddenly powered on after a power outage, when escaping to the top of the car, the elevator suddenly starts running, which is more dangerous than being inside the elevator car, increasing the difficulty of rescue. The safety of escaping through the safety window cannot be guaranteed, so safety windows for elevator escape are not widely used. For this reason, a car top with waterproof safety windows is proposed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a car roof with a waterproof safety window. When the safety window is used, the power to the electrical equipment will be cut off, ensuring the safety during escape, which is conducive to improving the practicality of the device.
