具体地，所述靠背机构31通过所述第三座框支架329和所述第一连杆324与所述座板联动机构32转动连接。所述靠背机构31通过与所述座板联动机构32的联动实现其向前或向后倾倒的调节运动。
具体地，所述座板联动机构32上还设置有第一限位件7、第二限位件8和第三限位件9，所述第一限位件7固定在所述第二座框支架328上，所述第二限位件8固定在所述第三座框支架329上，所述第三限位件9固定在所述第一座框支架327上，当所述伸展支架3收缩至极限位置时，所述第一限位件7与所述第一连杆324相抵触，所述第二限位件8与所述第二支撑件322相抵触，所述第三限位件9与所述L形座框安装板323和第三连杆326相抵触。所述第一限位件7、第二限位件8第三限位件9用于在所 述伸展支架伸展或收缩过程中通过与其他连接件的位置相抵触来限定所述靠背机构31和腿部伸展机构33的调整范围。在一些实施例中，所述限位件可以是限位销或限位套。
具体地，所述L形座框安装板323上还设置有座框保护板34，所述座框保护板34固定在所述L形座框安装板323的弯折处。所述座框保护板34用于保护和加强所述L形座框安装板的强度，增强沙发承重能力。在实际应用中，所述座框保护板34根据需求可以为板状、杆状或角铁状。
具体地，所述腿部伸展机构33设置在所述座板联动机构32的前端，所述腿部伸展机构33与所述L形座框安装板323转动连接。所述腿部伸展机构33包括平行设置的第一伸展件331和第二伸展件332，所述第一伸展件331与所述第一连动杆22转动连接，所述第二伸展件332与所述L形座框安装板323转动连接。
具体地，所述沙发联动装置上还设置有至少一个平衡杆4，所述平衡杆4的两端分别固定在两个所述第二支撑件322上。在一些实施例中，所述平衡杆4可以根据需求设计成具有弧度的圆管，也可以是方管或其他形状的杆件或板件，所述平衡杆4具有增强沙发稳定性和保证沙发左右两侧伸展支架受力平衡的作用。
具体地，所述沙发联动装置上还设置有至少一个抗扭杆5，所述抗扭杆5的两端分别固定在两个所述第一支撑件321上。在一些实施例中，所述抗扭杆5也可以是具有弧度的圆管、方管或其他形状的杆件或板件，具有在防止两侧伸展支架3在伸展或收缩的过程中产生扭转和两侧受力不平衡的作用。
本实施例的运动原理是驱动电机61驱动丝杠62旋转，从而带动滑动件24沿着滑轨21往复运动，以带动与滑动件24相连的第二连动杆23和与滑轨21的一端相连的第一连动杆22产生旋转和平移运动，最终带动两侧的伸展支架3伸展和收缩。
本发明沙发联动装置三种姿态的变换。坐姿状态，此时伸展支架3收缩至极限状态，靠背机构31和腿部伸展机构33均收拢于中间座板联动机构32，此时所述第一连动杆22和第二连动杆23距离最近。如图3所示， 休闲姿态，此时靠背机构31保持坐姿时的角度基本不变，腿部伸展机构33向前展开到搁脚部与地面平行，在驱动电机的驱动下滑动件24带动第二连动杆23向前平移，第一连动杆22旋转一定角度并向前平移。如图4所示，躺姿状态，在休闲姿的基础上座板联动机构32带动腿部伸展机构33继续向前平移，同时靠背机构31向后倾倒，此时所述第一连动杆22和第二连动杆23之间距离最远。
本发明两伸展之架之间设置有滑动机构和驱动机构，其中驱动机构控制滑动件带动第一连动杆和第二连动杆运动，以使得两个伸展支架伸展或收缩，其中驱动电机与丝杠滑轨结合的驱动方式结构简单、精确度高、降低噪音、节约成本、便于精密控制。本发明驱动电机的一端通过第一转轴与第一连动杆转动连接，第一连动杆与腿部伸展机构连接，伸展支架运动中驱动电机是随第一连动杆向前平移运动的，整个驱动机构的重心在沙发座椅的前端，使得人坐在沙发上时腿部伸展机构的伸展和收缩更加自如和平稳，避免产生晃动的情况。本发明第一连动杆设置在两个座板联动机构之间，第二连动杆设置在两个腿部伸展机构之间，既可以通过第一连动杆和第二连动杆的运动分别驱动座板联动机构和腿部伸展机构的运动，还起到了支撑和平稳装置的作用。
应当理解的是，本发明的上述具体实施方式仅仅用于示例性说明或解释本发明的原理，而不构成对本发明的限制。因此，在不偏离本发明的精神和范围的情况下所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
