Description

Technical Field

[0001] The utility model relates to the technical field of elevator cars, in particular to a light curtain structure for an elevator door machine of an elevator car type. Background Art

[0002] An elevator light curtain is a light-based elevator door safety device suitable for passenger and freight elevators to protect passengers. It consists of infrared emitters installed on both sides of the elevator car door. Each emitter contains an infrared emitting diode. Under the control of the MCU, the emitting and receiving diodes activate sequentially, continuously scanning the car door area from top to bottom, forming a dense infrared protective light curtain. If any beam of light is blocked, the control system immediately outputs a door-opening signal, causing the car door to stop closing and reverse open. The elevator door will not close normally until passengers or obstructions have left the warning area, thus achieving safety protection and preventing accidents involving people being trapped in the elevator.

[0003] Usually, when installing the light curtain for an elevator door machine, the light curtain needs to be installed in two different height areas inside the car, commonly at 2.2-2.5 meters and 10-15 centimeters from the ground, resulting in two groups of light curtains installed at the upper and lower ends of the car. However, depending on the elevator model and function, the installation positions of the upper and lower light curtains will change. During the process of adjusting the installation position of the light curtain, the installation positions of the light curtains on both sides will deviate. The deviation of the installation positions of the light curtains on both sides will affect the laser transmission effect, resulting in the failure to achieve the safety protection purpose, which will lead to the occurrence of elevator pinching accidents. For this reason, we propose a car-type elevator door machine light curtain structure. Utility Model Content
