Principle of electric telescopic door

Electric retractable door is a modern category, its main feature is that it can automatically expand and contract, which is convenient for people to enter and exit. Its principle is to use the motor to drive the expansion and contraction of the door body, thus realizing the automatic opening and closing of the door body. The electric retractable door consists of a door body, a motor, a control system and other parts, and its working principle is mainly divided into the following steps:

1. Sensor detection: When someone or a vehicle approaches the door, the sensor at the door will automatically detect it and send a signal to the control system.

2. Control system processing: After receiving the signal from the sensor, the control system will process it according to the preset program to control the motor to start.

3. Motor drive: After the motor is started, it will drive the door to expand and contract, and the door will automatically open or close.

4. Safety protection: If there are obstacles or abnormal conditions during the door movement, the control system will immediately stop the motor movement to protect the safety of the door body and users.

applied technology

Electric retractable doors are widely used, which can be used in the entrances and exits of shopping malls, airports, hospitals, hotels, factories and other places to facilitate people's access. At the same time, the electric retractable door also has the following advantages:

1. High degree of automation: the electric telescopic door is driven by a motor, which can realize the automatic opening and closing of the door body and save the trouble of manual operation.

2. Save space: the door body of the electric retractable door can automatically expand and contract, which will not occupy too much space and is convenient for people at the door.

3. High safety: the electric retractable door is equipped with sensors and control system, which can realize obstacle detection and safety protection and ensure the safety of users.

4. Beautiful and generous: the design of the electric retractable door is simple and generous, which can complement the appearance of the building.

operation sequence/order

The operation steps of the electric telescopic door are as follows:

1. When approaching the door, the sensor at the door will automatically detect and start the electric retractable door.

2. The door body automatically retracts and opens or closes the door.

3. In the process of door movement, if there are obstacles or abnormal conditions, the control system will immediately stop the movement of the motor to protect the safety of the door body and users.

4. After the user passes through the door, the electric telescopic door will automatically close to ensure the safety and traffic efficiency of the door.
