Abstract

The present invention provides an anti-pinch automatic door, including: a guide rail, a first door body and a second door body slidingly connected with the guide rail, a motor for pushing the first door body and the second door body, and multiple infrared detectors , Hall sensor and controller, the first door body is provided with the first anti-clamping edge, the second door body is provided with the second anti-clamping edge, the output shaft of the motor is provided with a magnetic ring, and the Hall sensor is arranged at the output of the motor On the side of the shaft, a plurality of infrared detectors are arranged on the second elastic buffer at intervals along the length direction of the second elastic buffer, and the infrared detectors and Hall sensors are respectively connected to the controller for signals, and the controller controls the connected motor. The present invention realizes multiple protection through a plurality of infrared detectors, first and second anti-pinch sides and Hall sensors, and effectively prevents people from being pinched by the first and second doors being closed.

Description

technical field [0001] The invention relates to the technical field of automatic doors, in particular to an anti-pinch automatic door. Background technique [0002] At present, in order to facilitate entry and exit, automatic doors are often used in office places, and the automatic doors can realize the function of automatically opening or closing according to the received signal. At present, infrared detectors are generally used to identify whether there are foreign objects to realize the protection of the human body, but there are easy protection blind spots, and accidents are still prone to occur. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an anti-pinch automatic door. [0004] An anti-pinch automatic door proposed by the present invention includes: a guide rail, a first door body, a second door body, a motor, a plurality of infrared detectors, a Hall sensor and a controller; ...
