其中，驱动机构包括用于提供动力的动力组件和用于带动摇篮本体90运动的连杆组件，连杆组件底部与动力组件相连，顶部与摇篮本体90相连；底座10上设置有支撑板20，动力组件通过支撑板20固定在底座10上。
如图3所示，连杆组件包括动力杆180和从动杆60，动力杆180一端与动力组件相连，另一端与从动杆60底端铰接；从动杆60顶端与摇篮本体90相连。进一步的，从动杆60数量为两个，分别设置在动力杆180的两侧。其中，动力杆180与从动杆60上均设置有轴承支架，动力杆180和从动杆60通过两个轴承支架相连。
继续参阅图3，连杆组件还包括支撑杆80和平衡杆100，支撑杆80与从动杆60平行设置，平衡杆100与动力杆180平行设置；动力杆180与平衡杆100间设置有连接块70；平衡杆100一端铰接在支撑板20上，另一端铰接在连接块70上；支撑杆80一端铰接在连接块70上，另一端铰接在摇篮本体90 上。平衡杆100与动力杆180以及从动杆60和支撑杆80能够通过连接块70形成两个平行四边形，不仅能够增加自由度，还能够起到支撑以及防止摇篮本体90侧翻的作用，保证运动过程中摇床主体始终保持水平。本实施例中，支撑杆80和平衡杆100与连接块70间均通过光杆连接。之所以采用光杆连接而不采用轴承，是为了有效节约成本。
具体的，连接块70呈三角形，连接块70靠近上侧的顶点铰接在动力杆180和从动杆60的连接点处，靠近下侧的顶点与平衡杆100相铰接，连接块70位于中间的顶点与支撑杆80相铰接。
其中，摇篮本体90底部安装有多个连接板280，从动杆60和支撑杆80分别铰接在连接板280上。连接板280呈L形，且与从动杆60相连的连接板280设置在摇篮本体90内侧，与支撑杆80相连的连接板280设置在摇篮本体90外侧。
如图2所示，本实施例的动力组件包括电机110、蜗轮140和蜗杆150，电机110与蜗杆150传动连接；蜗轮140与蜗杆150相啮合；蜗轮140的中心连接有传动轴，传动轴穿过支撑板20与动力杆180相连。电机110输出端与蜗杆150尾端均设置有同步带轮120，两个同步带轮120通过同步带130传动连接以使电机110驱动蜗杆150运动。实际上，动力组件还可为两个互相啮合的齿轮，通过齿轮进行动力传动，之所以本实施例采用蜗轮140蜗杆150进行传动，是因为本实施例的装置在运行中惠东动力组件产生较大载荷，蜗轮140蜗杆150具有自锁功能，安全性更高。另外，本实施例通过设置两级传动的方式，能够降低装置运行过程中对电机110的作用力，从而降低电机110的扭矩，减轻电机110的发热量，使整体装置性能达到最佳。
如图4所示，支撑板20的顶部设置有承载梁40，承载量两端均设置有减重组件，减重组件包括两个呈V形设置的承载杆50，两个承载杆50底部交点固定在支撑板20端部，顶部与摇篮本体90相抵触；两个承载杆50间设置有减重弹簧260。具体的，承载杆50顶端连接有滑轮270，承载杆50通过滑轮 270与摇篮本体90相抵触。装置运动时，通过利用减重弹簧260伸缩量能够大大降低整体机构的运行载荷，从而提高装置整体的结构强度和使用寿命，同时减少工作过程中的能耗。
为进一步提高减重效果，提高装置整体的载重力，如图4所示，动力杆180上设置有第一扭簧170，第一扭簧170一端固定在动力杆180上，另一端下方设置有第一档杆230，第一档杆230固定在支撑板20上；平衡杆100上设置有第二扭簧160，第二扭簧160一端固定在平衡杆100上，另一端下方设置有第二档杆240，第二档杆240固定在支撑板20上。通过设置第一扭簧170和第二扭簧160，能够与减重弹簧260进行配合，利用扭簧的扭矩及旋转力降低装置整体运行时的载荷，从而降低电机110的扭矩，减少能耗，降低电机110的发热量。
继续参阅图4，支撑板20上设置有第一限位柱210和第二限位柱220，第一限位柱210设置在动力杆180与传动轴连接点的上方以对动力杆180运动进行限位；第二限位柱220设置在平衡杆100与支撑板20连接点的下方以对平衡杆100运动进行限位。第一限位柱210和第二限位柱220分别设置在上下两个方位，通过分别对动力杆180和平衡杆100的运动路径进行限位，进而对连杆组件整体进行限位，从而提高装置整体的运行安全性。
其中，支撑板20上设置有光电开关200，动力杆180与传动轴相连的一端设置有与光电开关200相配合的感应块190。当需要开启或切换运动轨迹时，通过光电开关200能够得到一个复位信号，使运动装置复位。
如图1所示，本实施例中还包括壳体30，壳体30与支撑板20形成传动箱体，动力组件设置在传动箱体内，支撑板20和壳体30上均设置有凹槽，承载梁40一端设置在凹槽内，另一端底部设置有支撑柱250。
本实施例的运动装置运行原理如下：工作时，两个驱动机构中的电机110通过蜗轮140蜗杆150分别带动两组连杆组件运动，通过控制两个电机110的正反转及转动速度，即可使摇篮主体沿平面内任意轨迹进行运动。
总之，本发明的用于婴儿摇篮的运动装置整体结构简单，成本低，能够实现多种不同的运动轨迹，且整体载重高，能够满足使用需要。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
