Elevator car with safety protection function

Abstract

The invention discloses an elevator car with a safety protection function and relates to the technical field of elevators. The elevator car comprises an elevator car body. A protection plate is slidingly arranged at the bottom of the elevator car base plate. Two symmetric oblique sliding slots are formed in the protection plate. Two drive blocks are respectively arranged in the sliding slots and fixedly connected with an elevator car door respectively. Under an opening and closing action of the elevator car door, the protection plate is driven by the drive blocks to extend out of or retract from the bottom of the elevator car bottom. Two infrared detection bars are respectively arranged on one position with height of 0.2-0.5m and the other position with height of 1.0-1.2m on an inner wall of the elevator car body. Signal output ends of the infrared detection bars are respectively connected to an opening and closing control system of the elevator car door. A controller is arranged in the opening and closing control system and stops the elevator car door closing when receiving output signals sent from the infrared detection bar at the position of 0.2-0.5m. By the elevator car, gap between the elevator car door and an elevator well door is timely covered, and dangers to children when they take the elevator alone are reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator car with a safety protection function. Background technique [0002] With the improvement of living standards, a large number of high-rise buildings have sprung up, and elevators have become something that everyone has to face every day. People are paying more and more attention to the safety of elevators. The development of science and technology has improved the safety of elevators day by day, but because the elevator car runs at high speed in the elevator shaft, there is generally a wider gap between the car and the elevator shaft. Especially the gap between the elevator car door and the elevator shaft door. Although the gap is not big, it is enough for children's feet and the heels of high-heeled shoes to get stuck in it, and it often causes keys, bank cards, fruit cores, etc. to fall out. The existence of this gap will cause personal injury and foreign objects...
