Abstract

The invention provides an anti-pinch automatic door. The door comprises a guide rail, a first door body and a second door body which are connected with the guide rail in a sliding mode, a motor used for pushing the first door body and the second door body, a plurality of infrared detectors, hall sensors and a controller; the first door body is provided with a first anti-pinch edge; the second doorbody is provided with a second anti-pinch edge; a magnetic ring is arranged on an output shaft of the motor; the hall sensors are arranged on the peripheral side of the output shaft of the motor; theplurality of the infrared detectors are arranged on a second elastic buffer part at intervals in the length direction of the second elastic buffer part; the infrared detectors and the hall sensors are in signal connection with the controller; and the controller is in control connection with the motor. According to the door, the multiple protection is achieved through the plurality of infrared detectors, the first anti-pinch edge, the second anti-pinch edge and the hall sensors so that the first door body and the second door body which are being closed can be effectively prevented from pinching people.

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 will automatically open or close according to the received signal. At present, infrared detectors are generally used to identify whether there are foreign objects to protect the human body, but there is a protection blind spot and accidents are still prone to occur. Summary of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes an anti-pinch automatic door. [0004] An anti-pinch automatic door provided 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; [0005] The first door body and the second door body are slidably con...
