Abstract

The invention provides an automatic door and its automatic door opening and closing device. The automatic door opening and closing device includes a housing and a door opening and closing assembly. The housing is provided with a storage cavity and an opening communicating with the storage cavity. The housing is used for connecting the door body; The assembly is arranged in the storage cavity. The door switch assembly includes a motor and a roller. The roller is connected to the motor and is used to rotate at a preset speed driven by the motor. The roller is exposed through the opening and is used to contact the ground. By setting the door opening and closing assembly in the automatic door opening and closing device, when the motor drives the roller to rotate, the friction force between the roller and the ground will push the door connected to the roller to move relative to the ground, thereby realizing automatic door opening and closing. The housing for accommodating the door switch assembly can protect the door switch assembly and prevent damage to the door switch assembly caused by external dust or impurities.
