[0022] 下面结合附图并通过实施例对本发明作进一步说明。
[0023] 本发明实施例活动沙发电动机械伸展装置由机械伸展装置、 电动装置组成， 所 述机械伸展装置为现有技术， 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。 作为一种特例， 所述机械伸展装 置的左侧部件、 右侧部件均设置有腿部连接件 4、 上升连接件 10、 安装板 16、 脚 板 17、 脚一杆 18、 脚二杆 19、 小脚板 20、 滚动槽连接件 24、 靠背件 25、 滚轮 26 、 脚三杆 27、 前连接件 28、 座椅板 29、 腿部驱动连接件 30、 轮子控制连接件 32 、 轮子连接件 33、 后销子连接件 34， 脚板 17、 小脚板 20、 腿部连接件 4分别与脚 一杆 18、 脚二杆 19转动连接， 脚三杆 27与脚二杆 19、 腿部驱动连接件 30、 座椅 板 29转动连接， 座椅板 29与上升连接件 10、 靠背件 25转动连接， 靠背件 25与上 升连接件 10、 后销子连接件 34、 滚动槽连接件 24转动连接， 上升连接件 10与前 连接件 28转动连接， 后销子连接件 34与安装板 16、 轮子连接件 33转动连接， 轮 子控制连接件 32与轮子连接件 33、 安装板 16转动连接， 腿部驱动连接件 30、 后 销子连接件 34通过滚轮 26轴转动连接， 滚轮 26在滚动槽连接件 24的槽 37内运动 ， 安装板 16固定在活动沙发的底座 （本实施例为摇椅底座 31) 上， 脚二杆 19上 设置有第一限位 21， 座椅板 29上设置有第二限位 22、 第三限位 23， 第一限位 21 与腿部连接件 4接触起限位作用， 第二限位 22、 第三限位 23与上升连接件 10接触 起限位作用。 机械伸展装置可以有一些变形， 但其驱动原理和核心部分是相同 或者相似的， 特别是其与电动装置连接的腿部连接件 4、 上升连接件 10、 安装板 16是相同或者相似的。
[0024] 本发明实施例的设计要点是电动装置， 所述电动装置由电机 3、 电机前连接管 1 、 电机头安装件 2、 电机运动滑块 5、 电机后连接管 12、 滑块安装件 13、 转动连 接件 7、 转动弯件 15组成， 电机 3采用导轨电机， 电机 3头通过第四转轴 11与固定 在电机前连接管 1上的电机头安装件 2转动连接， 电机前连接管 1固定在机械伸展 装置的腿部连接件 4上， 电机运动滑块 5在电机 3的导轨 35上运动， 电机运动滑块 5通过第五转轴 14与固定在电机后连接管 12上的滑块安装件 13转动连接， 电机后 连接管 12固定在转动弯件 15上， 转动弯件 15通过第三转轴 9与机械伸展装置上的 上升连接件 10转动连接， 转动连接件 7通过第二转轴 8与转动弯件 15转动连接， 同吋， 转动连接件 7通过第一转轴 6与机械伸展装置上的安装板 16转动连接。 本 发明所述活动沙发电动机械伸展装置的电机 3头通过电机前连接管 1驱动机械伸 展装置的腿部连接件 4， 电机运动滑块 5通过电机后连接管 12驱动转动弯件 15， 转动弯件 15驱动机械伸展装置的上升连接件 10， 使得电机 3驱动力最大程度上得 到利用， 节约能源， 减少机械磨损， 增强整体结构。
[0025] 本实施例所述电机头安装件 2倾斜向电机 3下方， 电机头安装件 2上的第四转轴 1 1低于电机前连接管 1， 使得电机 3头部安装位置相对比较低； 电机 3的导轨 35安 装在电机后连接管 12上， 电机运动滑块 5位于电机后连接管 12上方， 使得电机运 动滑块 5与电机 3头的高度相差比较小， 当电机运动滑块 5沿着电机 3上的导轨 35 运动吋， 电机 3的驱动力最大限度地与本实施例展幵方向一致， 进一步节约能源 ， 减少机械磨损， 增强整体结构。
[0026] 图 2〜图 3显示了活动沙发电动机械伸展装置从腿部收拢到完全展幵的过程， 通 过使用者控制电机按钮从而驱动电机 3运动， 电机 3上的电机运动滑块 5在导轨 35 上运动， 从而带动通过第五转轴 14与电机运动滑块 5转动连接的电机后连接管 12 ， 电机 3头通过第四转轴 11与固定在电机前连接管 1上的电机头安装件 2转动连接 ， 电机前连接管 1固定在机械伸展装置上的腿部连接件 4上， 电机后连接管 12固 定在转动弯件 15上， 转动弯件 15通过第三转轴 9与机械伸展装置的上升连接件 10 转动连接。 由于人的自身重力， 导致电机运动滑块 5运动过程中， 座椅板 29上的 第二限位 22、 第三限位 23分别与上升连接件 10接触， 从而达到限位的作用， 使 座椅板 29、 上升连接件 10、 靠背件 25、 转动弯件 15、 电机后连接管 12、 滑动安 装件 13、 电机运动滑块 5成为一个整体， 从而导致电机 3的运动带动固定在电机 前连接管 1上的腿部连接件 4转动， 腿部连接件 4的转动带动脚一杆 18、 脚二杆 19 转动， 然后带动脚三杆 27相对于座椅板 29转动。 当固定在脚二杆 19上的限位钉 2 1与腿部连接件 4接触吋， 腿部伸展到位， 从而实现了脚板 17从收拢到完全展幵 的过程。
[0027] 图 3〜图 4显示了活动沙发电动机械伸展装置从腿部完全展幵到靠背完全倾倒的 过程， 当腿部完全展幵的吋候， 固定在脚二杆 19上的限位钉 21与腿部连接件 4接 触， 从而使脚板 17、 脚一杆 18、 脚二杆 19、 小脚板 20、 第一限位 21、 第二限位 2 2、 第三限位 23、 腿部连接件 4、 座椅板 29成为一个整体， 当电机 3继续运行吋， 电机运动滑块 5带动滑块安装件 13运动， 滑块安装件 13带动电机后连接管 12运动 ， 电机后连接管 12带动转动弯件 15运动， 由于转动弯件 15通过第三转轴 9与机械 伸展装置上的上升连接件 10转动连接， 转动连接件 7通过第二转轴 8与转动弯件 1 5转动连接， 同吋， 转动连接件 7通过第一转轴 6与机械伸展装置上的安装板 16转 动连接， 而安装板 16固定在摇椅底座 31上固定不动， 进而带动上升连接件 10的 上升运动， 上升连接件 10的上升运动带动靠背件 25的转动， 靠背件 25的转动带 动滚动槽连接件 24的运动， 腿部驱动连接件 30、 滚轮 26、 后销子连接件 34转动 连接， 滚轮 26在滚动槽连接件 24的槽 37内运动， 当电机 3上的电机运动滑块 5运 动到电机 3的最后限位点 （最大伸展幅度） 吋， 电机运动滑块 5停止向后运动， 从而实现靠背件 25的完全倾倒的过程。
工业实用性
[0028] 本实施例的运动原理是通过电机 3上的电机运动滑块 5在导轨 35上运动， 从而带 动通过第四转轴 14与电机运动滑块 5转动连接的电机后连接管 12， 电机 3头通过 第四转轴 11与固定在电机前连接管 1上的电机头安装件 2转动连接， 电机前连接 管 1固定在机械伸展装置的腿部连接件 4上， 电机后连接管 12固定在转动弯件 15 上， 转动弯件 15通过第三转轴 9与机械伸展装置的上升连接件 10转动连接， 由于 人的自身重力导致电机运动滑块 5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 2到图 3再到图 4的状态变化过程。 反之， 电机运动滑 块 6反向运动 （电机运动滑块 6向前运动， 在图 2〜图 4中为向左运动） 吋， 活动 沙发电动机械伸展装置可实现从图 4到图 3再到图 2的状态变化过程。 当活动沙发 电动机械伸展装置从图 2到图 3再到图 4的状态， 再从图 4到图 3再到图 2的状态， 就实现了活动沙发电动机械伸展装置的一次完整的电动驱动伸展和收拢的过程
[0029] 本实施例第四转轴 11与第五转轴 14的转动连接方式通过插销式连接， 实现了电 机 3的插销式连接。
[0030] 本实施例实现电机 3外形尺寸更小且电机 3头安装位置更低， 高度 H (如图 2所示 ) 比现有技术的活动沙发电动摇、 摆椅高度低 15mm， 从而解决了人坐沙发吋， 臀部与电机 3安装头触碰的危险。
[0031] 本实施例通过电机后连接管 12固定在转动弯件 15上， 转动弯件 15通过第三转轴 9与机械伸展装置的上升连接件 10转动连接， 从而使电机 3运动驱动力的方向最 大限度与转动弯件 15运行方向一致， 解决了电动 3驱动方式抖动及左右不平衡的 问题。
[0032] 本实施例将机械伸展装置及电动装置分别安装在摇椅底座 31 (如图 6所示） 及 摆椅底座 36 (如图 7所示） 上， 实现了电动摇椅与电动摆椅电动结构的统一， 从 而节约了活动沙发电动摇椅、 摆椅的控制成本。 机械伸展装置可以有一些变形 ， 但其驱动原理和核心部分是相同或者相似的， 特别是其与电动装置连接的腿 部连接件 4、 上升连接件 10、 安装板 16是相同或者相似的。
[0033] 本实施例改进了活动沙发的电动驱动方式， 有利于提高活动沙发电动安装及运 行效率， 提高了活动沙发的自动化程度和舒适性。
[0034] 凡是本发明的简单变形或等效变换， 应认为落入本发明的保护范围。
