What is an automatic door

　　Automatic doors are doors that are opened and closed by a motor, which can automatically open or close when sensing a signal or based on a preset time. The main types of automatic doors include:

　　1. Sensor automatic doors. They automatically open when sensing human movement or other objects approaching, used in commercial stores, office buildings, etc.

　　2. Revolving automatic doors. The door body has a rotating structure, automatically rotating to open and close, used in places that require quick entry and exit and larger passageways.

　　3. Delay automatic doors. They can automatically open and close based on a preset time, used for doors that need to close automatically after a certain time, such as garage doors.

　　4. Interlocking automatic doors. Two door bodies are interconnected; when one door opens, the other door closes, used in situations that require limiting airflow or temperature loss.

　　5. Safety airbag automatic doors. The door body is equipped with an airbag device, which activates upon collision with an object, stopping or reversing the door's movement, enhancing safety, used in crowded places.

　　The main advantages of automatic doors are:

　　1. Convenient and efficient. They open and close automatically, requiring no manual operation, resulting in high passage efficiency.

　　2. Small footprint. Automatic doors move idly, requiring no space for door opening, thus occupying a small area.

　　3. Good energy-saving effect. They open and close quickly, have good sealing, effectively avoiding hot and cold air loss, achieving good energy-saving results.

　　4. Safe and reliable. Automatic doors have multiple safety protection devices such as sensing and anti-pinch, ensuring high safety during use.

　　5. Aesthetically pleasing. Automatic doors have a stylish design, are high-end and elegant, enhancing the appearance of the building.

　　6. Increase mechanical beauty. The process of opening and closing automatic doors is orderly, reflecting a modern mechanical feel, enhancing the mechanical aesthetic of the building.

　　7. Convenient for people with disabilities. Automatic doors can open automatically at any time, making it easier for people with mobility difficulties and children to use.

　　In summary, automatic doors, with their many advantages such as speed and efficiency, energy-saving and environmental protection, safety and reliability, and aesthetic appeal, are suitable for various commercial, public, and office buildings, and have become one of the indispensable types of doors in modern architecture.
