卷帘驱动装置 技术领域
本申请实施例涉及窗帘技术领域，特别是涉及一种卷帘驱动装置。
 背景技术
现有的弹簧卷帘的卷绕筒的两端还分别安装于相应的支架上，且卷绕筒内设置有驱动器、螺旋弹簧、阻尼器和限位器。当需要放下帘时，只需向下拉帘布，帘布会带动卷绕筒旋转而进而相对于螺旋弹簧发生转动，而使得螺旋弹簧发生扭转变形积累弹力，同时借助于阻尼器而能使帘布停留在帘布有效行程范围内的任何高度位置。而需要收起帘布时，只需向上推帘布，可使螺旋弹簧的作用力克服阻尼器的阻尼作用而带动卷绕筒反正旋转，从而将帘布重新卷绕至卷绕筒上。然而现有的弹簧卷帘内一般仅设置一个驱动器，输出的动力有限，即使设置有至少两个驱动器，至少两个驱动器的输出轴需要共轴并依次相对固定连接来形成一个整体对外输出动力，由于驱动器需要共轴设置，导致结构相对固化且组装精度要求高，也不利于整体结构的优化设计。
