上滑式车库门按照洞口上方的空间可分为单轨和双轨两种，但是它和上排挂车库门的运行方式都是一样的，它在启动的时候，门体在轨道运行且垂直直线上升。
According to the space above the opening, the sliding garage door can be divided into monorail and double track. However, the operation mode of the upper row garage door is the same. When it is started, the door body runs on the track and rises vertically.
它由平衡系统、固定导轨和多块门板连接而成，门侧边装有滚轮，开启时门沿导轨运动，向上转折提升，门内置扭簧，扭力和门重量相当，使门体处于“零重量”状态，且在轨道内靠滑轮运行。
It is composed of a balance system, a fixed guide rail and a number of door panels. A roller is installed on the side of the door. When the door is opened, the door moves along the guide rail, turning upward and lifting. The torsion spring inside the door is equivalent to the weight of the door, so that the door body is in the "zero weight" state and operates by the pulley in the track.
智能车库门不同于以前的车库门要自己手动开启，它是利用遥控或者感应开关车库门，还有很多智能性，比如说遇阻反弹、应急系统、自锁等功能。
The intelligent garage door is different from the previous garage door, which needs to be opened manually. It uses remote control or induction to open and close the garage door. There are many intelligent functions, such as rebound in case of resistance, emergency system, self-locking and other functions.
