电动伸缩门别名"电动门""或"电动折叠门"。电动伸缩门主要由门体、驱动器、控制系统构成。伸缩门的门体采用优质铝合金及普通方管管材制作，采用平行四边形原理铰接，伸缩灵活行程大。
The electric expansion door is also known as "electric door" or "electric folding door". The electric expansion door is mainly composed of door body, driver and control system. The door body of the expansion door is made of high-quality aluminum alloy and common square pipe material. It is hinged on the principle of parallelogram, with large flexible expansion stroke.
自动伸缩门，按"电动"分为普通型(需配功率控制箱，功率部分在控制箱里)机电一体化型(功率部分，及逻辑电路在电装本体上。此类电装性价比高，可靠性好),智能一体化型(只是在机电一体化上加了液晶显示，电子行程，电子力矩，遥控调试等功能),智能一体化只是对电装本体的更新，智能一体化的发展是总线型的智能一体化，及功率部件的更新，变频器的使用，及变频型。 电动伸缩门广泛适用于各类工矿厂房、车间、仓库、机房、车库等场合作为活动围墙，大大扩大了电动伸缩门的应用范围。
The automatic expansion door is divided into ordinary type (power control box is required, and the power part is in the control box) and electromechanical integrated type (power part and logic circuit are on the electrical installation body) according to "electric". This kind of electrical installation has high cost performance and reliability), intelligent integration (only the LCD display, electronic travel, electronic torque, remote control debugging and other functions are added to the mechanical and electrical integration), intelligent integration is only the renewal of the electrical installation body, the development of intelligent integration is the bus type intelligent integration, the renewal of power components, the use of frequency converter, and frequency conversion type The electric expansion door is widely used in all kinds of industrial and mining plants, workshops, warehouses, machine rooms, garages and other fields to form a movable enclosure, greatly expanding the application scope of the electric expansion door.
