[0002] Elevator hall doors are typically equipped with anti-pinch protection devices to prevent passengers from being trapped during door closing. These devices can be mechanical safety touch panels or light curtain sensors. A mechanical safety touch panel is installed on the edge of the elevator door; if the touch panel encounters an obstacle when the door closes, it triggers the door to reopen. A light curtain sensor detects objects within the door area using infrared beams; if an object blocks the beam, the door reopens. This utility model's elevator hall door safety protection structure is mainly composed of components such as a first servo motor, a second servo motor, an upper landing sill, a lower landing sill, a first elevator hall door, a second elevator hall door, a sliding track, a slider, a partition, an insert, a slot, a socket, a mounting groove, a through hole, a locking block, a locking groove, a connecting hole, a transmitter, a receiver, and a placement groove. Existing elevator hall door safety protection structures mostly use a single transmitting device. If the transmitting device malfunctions, it will affect the normal operation of the elevator hall door, potentially causing injury to users. Therefore, a comprehensive elevator hall door safety protection structure is essential. Utility Model Content

[0020] Compared with the prior art, this utility model provides a safety protection structure for elevator hall doors, which has the following beneficial effects:

[0021] This utility model improves an elevator hall door safety protection structure. When using the elevator hall door safety protection structure, the first and second servo motors are first connected to an external power supply. The first and second servo motors drive the slider to move left and right within the slide groove via threaded columns, thereby enabling the first and second elevator hall doors to move left and right inside the slide groove. When the first and second elevator hall doors are open, the light emitted by the transmitter at the right end of the first elevator hall door is received by the receiver at the left end of the second elevator hall door. When the user blocks the light, the receiver will not receive a signal. The system transmits data to the main control chip, which then controls the first and second servo motors to move the first and second elevator hall doors outwards, thus preventing users from being trapped by them. Since the transmitter and receiver use a dual-transmission mode, the failure of one will not affect the normal operation of the elevator hall doors. Furthermore, because the protective frame is made of rubber, it reduces the injury caused to users when they are trapped by the elevator hall doors. Through the combined use of dual transmitters, dual receivers, and the protective frame, the protective performance of the first and second elevator hall doors is enhanced.
