具体实施方式
[0015] 下面结合附图并通过实施例对本实用新型作进一步说明。
[0016] 本实施例在所述活动沙发电动机械伸展装置包括现有技术的机械伸展装置 （具 有相同的左侧部件、 右侧部件， 左侧部件与右侧部件通过固定部件固定连接） ， 所述机械伸展装置具有第三连杆 1、 第三脚杆 4、 底座 24， 其结构特点是其电 动装置由电机滑块连接管 2、 电机 5、 电机腿部固定管 6、 电机导轨 8、 电机滑块 2 2组成， 电机 5采用导轨电机， 电机 5头通过第二转轴 7与电机腿部固定管 6转动连 接， 电机腿部固定管 6固定在机械伸展装置上的第三脚杆 4上， 电机滑块 22通过 第一转轴 3与电机滑块连接管 2转动连接， 电机滑块连接管 2固定在机械伸展装置 上的第三连杆 1上， 电机滑块 22在电机 5的电机导轨 8上运动。
[0017] 本实施例所述电机腿部固定管 6固定在机械伸展装置上的第三脚杆 4上， 实现电 机 5的推力直接作用于机械伸展装置的腿部结构， 电机滑块 22沿着电机导轨 8运 动， 使得电机 5的驱动力最大限度地与本实施例展幵方向一致， 从而节约能源， 减少机械磨损， 增强整体结构。
工业实用性
[0018] 本实施例的运动原理是通过电机 5上的电机滑块 22在电机导轨 8上运动， 从而带 动通过第二转轴 7与固定在第三脚杆 4上的电机腿部固定管 6， 电机腿部固定管 6 固定在机械伸展装置上的第三脚杆 4上， 由于人的自身重力导致电机滑块 22运动 过程中， 活动沙发电动机械伸展装置首先腿部结构展幵， 待完全展幵到限位与 接触面接触吋， 阻止腿部结构机械展幵， 从而带动活动沙发电动机械伸展装置 的靠背结构完全倾倒， 这样活动沙发电动机械伸展装置就实现了从图 1到图 2再 到图 3状态的过程。 反之， 电机运动滑块 22方向运动吋， 活动沙发电动机械伸展 装置可实现从图 3到图 2再到图 1状态的过程。 当活动沙发电动机械伸展装置处于 图 1， 即腿部完全收拢状态吋， 从而实现了活动沙发机械伸展装置的电动驱动功 能。
[0019] 本实施例第一转轴 1与第二转轴 7的转动连接方式通过插销式连接， 实现了电机 的插销式连接。
[0020] 本实施例取消了转轴传动件 20、 转动连杆 21的转动连接， 解决了电动驱动方式 抖动的问题。
[0021] 本实施例底座 24通过两个底部连接管 23固定连接， 结构简洁， 成本低， 取消了 对比电机连杆 15、 对比电动连杆 9与底座 24的连接。
[0022] 本实施例增加了活动沙发的电动新驱动方式， 取消了原有电动驱动方式装置， 有利于提高活动沙发电动安装及运行效率， 提高了沙发的自动化程度和舒适性
[0023] 凡是本实用新型的简单变形或等效变换， 应认为落入本实用新型的保护范围。
