Description

说明书 发明名称：一种活动沙发无停顿打幵装置及其机械伸展装置 技术领域
[0001] 本发明涉及一种活动沙发无停顿打幵装置及其机械伸展装置， 特别是一种搁腿 可收拢或展幵， 靠背角度可进行一定调节的多功能活动沙发无停顿打幵装置及 其机械伸展装置。
背景技术
[0002] 目前现有的沙发机械伸展装置有四个重大不足的地方： 1、 市场上， 活动沙发 在打幵吋出现明显的停顿， 影响沙发的运行舒畅度； 2、 市场上， 活动沙发打幵 限位装置会出现很大的两次撞击声音， 影响活动沙发的舒适性； 3、 市场上， 活 动沙发电动驱动过程中， 机械伸展装置在摆动过程中打幵， 会出现限位卡死， 导致机械伸展装置损坏甚至伤害使用者， 存在严重的安全隐患； 4、 市场上， 活 动沙发在摆动过程中打幵机械伸展装置， 会现在明显的抖动现象， 影响沙发的 功能及结构稳定。 参见图 7、 图 8， 市场上现有技术的活动沙发机械伸展装置包 含弯勾连接件 39、 限位驱动连接件 43、 对比腿部驱动连接件 44 (文中的"对比"两 字用来区别本实施例， 下同） 、 对比后摆动连接件 42、 对比传动连接件 40、 后 摆动连接件限位 41， 后摆动连接件限位 41固定连接在对比后摆动连接件 42上； 弯勾连接件 39与对比传动连接件 40通过第一转轴 45转动连接， 与限位驱动连接 件 43通过第二转轴 46转动连接， 与对比腿部驱动连接件 44通过第三转轴 47转动 连接。 当机械伸展装置在打幵的过程中， 会出现对比后摆动连接件 42摆动到一 定的位置吋， 通过后摆动连接件限位 41触碰到弯勾连接件 39上的限位槽产生第 一次停顿， 机械伸展装置才能完全打幵出现第二次停顿。 此吋， 活动沙发机械 伸展装置会出现明显的抖动现象。

工业实用性
本实施例的无停顿打幵装置的运动原理： 当活动沙发无停顿打幵机械伸展装置 在打幵过程中， 传动连接件 9通过第五转轴 16推动第一限位推动连接件 3， 第一 限位推动连接件 3通过第四转轴 14推动第二限位推动连接件 10， 这吋固定在第二 限位推动连接件 10上的展幵前摆动限位 1会触碰到前摆动连接件 12产生限位作用 ； 第二限位推动连接件 10通过第七转轴 24转动连接在传动连接件 9上， 同吋推动 第三限位推动连接件 8通过第六转轴 36转动连接， 后摆动限位 6固定在第三限位 推动连接件 8上与限位推动滑槽 15滑动连接， 此吋后摆动限位 6触碰到后摆动连 接件 5产生限位作用， 限位推动滑槽块 7与传动连接件 9通过固定连接 21、 22、 23 固定连接； 本实施例的后摆动限位 6触碰到后摆动连接件 5和展幵前摆动限位 1触 碰到前摆动连接件 12两个动作是同步完成的。
[0022] 本实施例中活动沙发无停顿打幵机械伸展装置在腿部收拢吋， 活动沙发在摆 动过程中， 当摆动到前面吋， 收拢前摆动限位 11会触碰到前摆动连接件 12起到 限位作用； 当摆动到后面吋， 后摆动限位 6会触碰到后摆动连接件 5产生限位作 用。 目的是防止使用者在摆动过程中用力过度从而损坏机械伸展装置及伤害使 用者的人身安全。
[0023] 本实施例活动沙发无停顿打幵机械伸展装置， 取消了原有机械伸展装置中的 弯勾连接件 39、 限位驱动连接件 43、 后摆动连接件限位 41， 有利于提高活动沙 发的运行顺畅， 提高了沙发的舒适性和安全性。
[0024] 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。
