[0041] 当感应组件感应到显示屏箱体 1从拼屏状态进入拆屏状态吋， 此吋感应组件首 先控制第二驱动电机 231转动， 并通过第二传动组件 232带动保护机构 21竖直向 上运动， 运动到位后， 感应组件控制第一驱动电机 221转动， 通过第一传动组件 222带动安装座 223水平向左运动， 从而带动第二驱动机构 23和保护机构 21水平 向左运动， 运动到位后， 保护板 211相对于显示屏箱体 1的侧面突出设置， 可对 显示屏箱体 1进行保护。
[0042] 综上所述， 本发明提供的一种带保护装置的 LED显示屏， 在显示屏箱体上设置 有保护装置， 当显示屏箱体处于拼屏状态吋， 保护装置自动收回， 不影响显示 屏箱体之间的拼接； 当显示屏箱体处于拆屏状态吋， 保护装置自动外伸， 对显 示屏箱体进行保护， 有利于延长显示屏箱体的使用寿命。
