The invention relates to an elevator car, an elevator car door and an elevator system. The elevator car comprises an elevator car door and a door frame, a gap communicated with the outside of the elevator car exists when the elevator car door is in a closed state, and the elevator car further comprises a fireproof sealing part which is arranged on the elevator car door and/or the door frame. And when the temperature of the environment where the fireproof sealing piece is located exceeds a preset value, the fireproof sealing piece expands so as to at least partially fill the gap. The device is simple in structure, easy to implement, low in cost, good in fireproof and heat insulation effects and the like, and capable of providing a safer, more reliable and more comfortable elevator taking environment for elevator passengers, thereby having very high practicability.
