Description

超声设备的旋转联动装置及超声设备 技术领域
本申请涉及一种医疗器械，具体涉及一种能够实现显示装置和控制面板同步联动的结构。
 背景技术
医护人员在使用带有操作面板的医疗仪器时（以超声诊断仪为例），往往基于操作、诊断、治疗的需要，尤其在做不同的体位检查时，要求操作面板能够灵活转动朝向医护人员或者病人，同时要求显示器也能同步朝向医护人员或者病人，方便进行操控设备或者展示诊断图像。
一般台式超声诊断设备均设置有控制面板与显示器及其支撑臂组件(以下简称显示装置)。通常超声诊断设备的常见结构形式主要有两种。第一种是控制面板与显示装置固定集成在一个平台上，常见为显示装置固定在控制面板上。当控制面板旋转时，显示装置因为固定在控制面板上，亦可同步进行旋转。第二种是控制面板与显示装置各自独立固定在机身上，使用者通过手动操作分别将显示装置和控制面板旋转到需要的位置。
以上第一种方案中，控制面板与显示装置固定集成在一个平台上，两者绕同一轴线转动，而控制面板与显示装置距离转动轴线的距离不同，尤其是显示装置通常是偏离转动轴线设置的，因此该结构占用体积庞大，而且由于最外沿距离转动轴线距离过长而导致设备在转动时所占据的空间过大。在医院使用场景中经常会出旋转过程中易碰撞到周围放置物品(如床、工作站、设备上的放置物品以及连接线缆)，或者由于床与机器过近导致无转动空间。而第二种方案中，医护人员转动控制面板后，仍需要再去转动显示器，增加了医护人员的操作动作，用户体验差。

实施例：
本实施例提供一种超声设备，具体来说为一种超声诊断仪。
请参考图1，该超声设备包括控制面板1、显示装置2、旋转联动装置3和主机9。该显示装置2可包括有显示器21及显示器支撑臂组件22。该显示器21可采用各种显示设备，用以显示各种图像或其他电子信息，例如用来显示处理过程的信息、处理完成的结果或者其它信息。显示器21可以是显示屏或带有触控功能的触控显示设备。该控制面板1上一般设置有按键、旋钮等，用户可以通过控制面板1对超声诊断仪进行操作。该超声设备还可配置如滚轮、手柄等部件，在此不再赘言。
在本实施例中，该控制面板1和显示装置2安装在旋转联动装置3上，而旋转联动装置3可安装在主机9上。
该旋转联动装置3用以实现两个以上部件的同步旋转。请参考图3-5，该旋转联动装置3包括第一旋转组件31、安装支架33、第二旋转组件35以及旋转运动传动件391。该第一旋转组件31和第二旋转组件35可以分别设置在安装支架33的两端331、335或其他位置。
该安装支架33作为第一旋转组件31和第二旋转组件35的安装结构。该第一旋转组件31用于安装控制面板1或其他部件。该第一旋转组件31装在安装支架33上且能够绕第一转动轴线在安装支架33上转动。该第二旋转组件35用于安装显示装置2或其他部件。该第二旋转组件35装在安装支架33上且能够绕第二转动轴线在安装支架33上转动。
该旋转运动传动件391是第一旋转组件31和第二旋转组件35之间的传动关键，其分别与第一旋转组件31和第二旋转组件35连接，将第一旋转组件31和第二旋转组件35中任一个的旋转运动传动至另一个，使第一旋转组件31和第二旋转组件35能够同步旋转。
请参考图1-4，在本实施例中，该控制面板1安装在旋转联动装置3的第一旋转组件31上。该显示装置2安装在第二旋转组件35上。该控制面板1和显示装置2通过旋转联动装置3使显示装置2和控制面板1实现同步旋转。
在本超声设备中，由于控制面板1与显示装置2各自的转动轴线旋转，因此转动时占用空间小，可解决现有控制面板以上整体转动占用体积大的问题。而且，相比通常所采用的旋转结构，该方案联动性较好，整体结构模块化设计，结构紧凑维护方便，占用空间小。
当然，本实施例所示是对显示装置2和控制面板1实现同步旋转。在其他实施例中，该可以将显示装置2和控制面板1替换为其他部件。或者，旋转联动装置3还可以包括第三旋转组件或更多旋转组件，从而使更多部件实现同步旋转运动。
进一步地，一种实施例中，该第一转动轴线与第二转动轴线平行。该第一旋转组件31和第二旋转组件35平行设置可便于旋转运动传动件391的设计，简化整体结构，无需复杂的传动结构就可实现同步旋转。
作为一种示例，请参考图4和5，一种实施例中，该第一旋转组件31具有第一传动件3121，当第一旋转组件31运动时，第一传动件3121以第一转动轴线为旋转中心线，能够绕第一转动轴线旋转。第二旋转组件35具有第二传动件3521，当第二旋转组件35运动时，第二传动件3521以第二转动轴线为旋转中心线，能够绕第二转动轴线旋转。该旋转运动传动件391分别与第一传动件3121和第二传动件3521连接，并形成同步旋转机构。该第一传动件3121的旋转运动传递至旋转运动传动件391，并带动旋转运动传动件391一起运动，这种运动可以是直线运动或旋转运动。该旋转运动传动件391在运动的同时，带动第二传动件3521产生旋转运动，从而实现第一传动件3121和第二传动件3521同步旋转。
对于第一旋转组件31和第二旋转组件35在安装支架33上的具体结构，请参考图4，一种实施例中，该第一旋转组件31具有第一转轴316。第二旋转组件35具有第二转轴356。第一转轴316和第二转轴356转动安装在安装支架33上。第一传动件3121与第一转轴316同轴心的一体转动。第二传动件3521与第二转轴356同轴心一体转动。具体地，该第一转轴316产生旋转运动时，将带动第一传动件3121产生同轴心的转动，而第二转轴356产生旋转运动时，将带动第二传动件3521产生同轴心的转动。
所说的一体转动可以通过将转轴（包括第一转轴和/或第二转轴）与对应的传动件（包括第一传动件和/或第二传动件）固定连接来实现。或者，可以采用摩擦传动、齿啮合传动和结构限位传动中的至少一种实现运动的传递，该方式可以通过使传动件和转轴分离的方式来解除联动。再或者，可以通过一些离合机构来完成一体转动，例如扭矩限制离合器，过载离合器或者超越离合器，该方式不仅可以保证转轴和传动件之间运动的传递，而且还可以通过设置额定的扭矩/转速来解除联动，一旦扭矩/转速超过置额定的扭矩/转速，传动件将不再随转轴转动。
该第一转轴316和第二转轴356可通过各类方式转动安装到在安装支架33上，例如轴承或其他结构。请继续参考图4，一种实施例中，该第一转轴316和第二转轴356的上端均具有沿径向向外凸起的卡台。第一转轴316和第二转轴356的下端分别固定连接有转动盘，转动盘位于第一转轴316和第二转轴356的下端。转动盘外径大于对应的第一转轴316或第二转轴356的外径，即安装在第一转轴316上的转动盘外径大于第一转轴316的外径，安装在第二转轴356上的转动盘外径大于第二转轴356的外径。该安装支架33具有安装孔，该第一转轴316和第二转轴356安装在对应安装孔内，并通过各自的卡台和转动盘定位在安装支架33上。该转动盘可以是与转轴316、356通过螺钉等方式锁紧固定。
进一步地，为了提高第一转轴316和第二转轴356旋转的平稳性。请参考图4，一种实施例中，该第一转轴316和第二转轴356各自的卡台与安装支架33之间分别设置有环形的固定盘317、357。固定盘317、357固定安装在安装支架33上，且固定盘317、357与对应第一转轴316和第二转轴356的外壁之间分别设置衬套318、358。这样，第一转轴316和第二转轴356可以更好的在安装支架33上旋转。同时，安装支架33的安装孔与对应的第一转轴316和第二转轴356之间也可以设置衬套319、359，使第一转轴316和第二转轴356在安装孔的孔壁内的旋转更平稳。
当然，以上所示结构仅是作为第一旋转组件31和第二旋转组件35可转动地安装到安装支架33的一种示例，其他实施例中也可采用其他结构，例如利用转轴与轴承的配合实现转动等。
进一步地，一种实施例中，该第一传动件3121和第二传动件3521可位于同一平面内，这样第一传动件3121和第二传动件3521的旋转运动也在同一平面，因此可以更容易地相互传递。当然，一些实施例中，该第一传动件3121和第二传动件3521也可以位于不同平面，这就需要旋转运动传动件391具备更复杂的传动结构。
一种实施例中，该第一传动件3121、第二传动件3521和旋转运动传动件391形成的同步旋转机构采用链轮链条传动结构来进行旋转运动的传动。
请参考图4和5，该第一传动件3121和第二传动件3521为链轮，该旋转运动传动件391采用链条。该链轮3121与链轮3521通过链条391联动，采用链轮395对链条的松紧程度进行装配调节。
如图5所示，当控制面板1转动时，比如顺时针旋转，会带动第一转轴316顺时针转动，同步带动链轮3121顺时针转动。通过链条391联动传动，链轮3521也会顺时针转动，同步带动第二转轴356顺时针转动，即带动显示装置2顺时针转动。实现了控制面板1与显示装置2的旋转联动运动效果。
另外，一种实施例中，该第一传动件、第二传动件和旋转运动传动件形成的同步旋转机构也可采用同步带传动结构实现，其实现方式同链轮链条实现原理相仿，这里不再详细描述。
此外，该第一传动件、第二传动件和旋转运动传动件形成的同步旋转机构可以采用滑轮绳索传动结构实现。如图6-8所示，一种实施例中，该第一传动件和第二传动件为滑轮3122、3522，该旋转运动传动件采用绳索392。该第一转轴316与滑轮3122相对于固定盘317可以旋转运动。第二转轴356与滑轮3522相对于固定盘357可以旋转运动。滑轮3122与滑轮3522通过绳索392缠绕联动，采用另一滑轮或者收线夹3962对绳索的松紧程度进行装配调节。
另外，一种实施例中，该第一传动件、第二传动件和旋转运动传动件形成的同步旋转机构也可采用无极皮带传动实现，其实现方式同绳索传动实现原理相仿，这里不再详细描述。
一种实施例中，该第一传动件、第二传动件和旋转运动传动件形成的同步旋转机构可以采用齿轮组传动结构实现。如图9所示，该第一传动件和第二传动件为齿轮3125、3525，该旋转运动传动件采用也是齿轮3985。第一转轴316与齿轮3125相对于固定盘317可以旋转运动。第二转轴356与齿轮3525相对于固定盘357可以旋转运动。齿轮3125与齿轮3525通过中间增加若干齿轮3985组成齿轮组啮合实现。
一种实施例中，该第一传动件、第二传动件和旋转运动传动件形成的同步旋转机构可以采用齿轮齿条传动结构实现。如图10所示，该第一传动件和第二传动件为齿轮3126、3526，该旋转运动传动件采用齿条3986。第一转轴316与齿轮3126相对于固定盘317可以旋转运动。第二转轴356与齿轮3526相对于固定盘357可以旋转运动。齿轮3126与齿轮3526通过与齿条3986啮合实现旋转运动联动。
当然，以上仅是几种同步旋转机构的示例，在其他实施例中，还有很多可以实现的方案：比如连杆组合、凸轮组合、凸轮与连杆组合、连杆与滑动组合、凸轮与滑动组合等等，无法穷尽列举，原理相近或基于上述展示的变形方案亦适用于本申请所示的同步旋转机构中。
另一方面，在通常的超声设备中，该显示装置2的位置会比控制面板1的位置更高，以满足使用者视觉要求和输入习惯。因此，一种实施例中，该第二旋转组件35用于安装显示装置2的安装位高于第一旋转组件31用于安装控制面板1的安装位。由此可使显示装置2的位置高于控制面板1的位置。
为了实现第二旋转组件35和第一旋转组件31之间的高度差，可以通过将第一转轴316和第二转轴356的长度设置为不同，或使两者向上伸出的高度具有设定的高度差，或者还可以通过其他结构使第二旋转组件35的安装位垫高。
请参考图11-13，一种实施例中，该第二旋转组件35还包括第三转轴366和传动轴368。该第三转轴366位于第二转轴356的上方。传动轴368同时与第二转轴356和第三转轴366同轴心连接，从而将第二转轴356的旋转运动传导至第三转轴366。第三转轴366用于安装显示装置2，且第三转轴366安装显示装置2的安装位高于第一旋转组件31用于安装控制面板1的安装位，同时可以使第一旋转组件31的旋转运动稳定的传动到第三转轴366上，或者使第三转轴366的旋转运动稳定的传动到第一旋转组件31上。
进一步地，请继续参考图11-13，一种实施例中，该安装支架33具有向上凸起的第二支架337，该第三转轴366转动安装在第二支架337上。这样第二转轴356和第三转轴366分别被稳定的支撑住，可使得该第二转轴356和第三转轴366的旋转运动更加稳定。
该第三转轴366在第二支架337上的安装结构可参考第一转轴316和第二转轴356，当然，也可以采用其他形式，例如通过轴承来实现。请参考图11和12，一种实施例中，该第三转轴366的上端具有沿径向向外凸起的第三卡台（第一转轴316和第二转轴356所具有的卡台可分别视为第一卡台和第二卡台）。第三转轴366下端固定连接有第三转动盘3621（第一转轴316和第二转轴356所连接的转动盘可分别视为第一转动盘和第二转动盘）。第三转动盘3621外径大于第三转轴366的外径。第二支架337具有安装孔，第三转轴366在对应安装孔内，并通过第三卡台和第三转动盘3621定位在第二支架337上。
同样地，该第三卡台与第二支架337之间也可设置有环形的第三固定盘367，该第三固定盘367固定安装在第二支架337上，且第三固定盘367与第三转轴366的外壁之间设置衬套，用以提高第三转轴366旋转的平稳性。
请参考图12，在采用了这种具有垫高结构的旋转联动装置3后，该显示装置2可位于较高的位置，满足使用者的视觉要求。而控制面板1则设置在较低的位置，以便使用者手动操作的需求，更符合人机工程学。
进一步地，一种实施例中，该第一旋转组件和第二旋转组件中至少其一还具有离合机构。离合机构用于使第一传动件和/或第二传动件与对应的第一转轴和/或第二转轴联动和解除联动。该离合机构可以只用来控制第一旋转组件或第二旋转组件中传动件和转轴之间运动的传递。或者，也可以同时在第一旋转组件或第二旋转组件分别设置离合机构，从而同时对第一旋转组件或第二旋转组件进行控制。
其中，离合机构可以是一种能够促使传动件和转轴分离和连接的机构，从而实现传动件和转轴的联动和解除联动。如上文所述，传动件和转轴可以采用摩擦传动、齿啮合传动和结构限位传动中的至少一种实现运动的传递，该方式可以便于离合机构使传动件和转轴连接和分离。或者，离合机构也可以是一类能够通过设置额定的扭矩/转速来解除联动的装置，例如扭矩限制离合器，过载离合器或者超越离合器。该方式不仅可以保证转轴和传动件之间运动的传递，而且一旦扭矩/转速超过额定的扭矩/转速，传动件将不再随转轴转动。
请参考图14和15，此处以第一旋转组件31为例进行说明，该第二旋转组件也可参照执行。该离合机构包括手动拨杆81和触发件85，手动拨杆81驱动触发件85运动。该手动拨杆81便于操作者进行控制，由使用者操控手动拨杆81的位置，从而驱动触发件85运动。该触发件85可以采用如图所示的传动轴或其他形式的结构。触发件85与第一传动件3121和/或第二传动件（图中未示出）配合，用于驱使第一传动件3121和/或第二传动件与对应的第一转轴316和/或第二转轴（图中未示出）联动和解除联动。例如，当手动拨杆81拨动到如图14所示位置时，该第一转轴316和第一传动件3121连接，从而一体转动。当手动拨杆81拨动到如图15所示位置时，该触发件85将推动第一传动件3121向远离第一转轴316的方向移动，该第一转轴316和第一传动件3121分离，从而解除一体转动。
进一步地，请继续参考图14和15，一种实施例中，该离合机构还包括复位弹性件（图中未示出）。手动拨杆81绕一个支点（转动轴83）转动形成杠杆结构。以手动拨杆81的支点为界，该手动拨杆81力臂较短的一端为驱动端。该触发件85在竖直方向上活动设置，且位于驱动端向下旋转的运动轨迹上，使驱动端在旋转过程中能够驱动触发件85向下运动，如图15所示。第一传动件3121和/或第二传动件位于对应触发件85的下方并且在触发件85驱动下脱离对应的第一转轴316和/或第二转轴，从而实现联动的接触。
该复位弹性件用于使触发件85以及对应的第一传动件3121和/或第二传动件向上复位。复位弹性件可采用弹簧，其可以是直接作用到第一传动件3121和/或第二传动件上，也可以作用到与第一传动件3121或第二传动件相连的部件上。当手动拨杆81拨动到如图14所示位置时，该复位弹性件将促使第一传动件3121和/或第二传动件复位，与对应的第一转轴316和/或第二转轴形成联动。
当然，在其他一些实施例中，该触发件85也可以与手动拨杆81形成直接或间接的连杆运动，从而驱使触发件85上下运动。
在其他一些实施例中，该触发件85和传动件（第一传动件3121和/或第二传动件）之间也可以设置为活动连接，从而由触发件85带动传动件脱离和靠近转轴，此时可以省略复位弹性件或者将复位弹性件设置到触发件85上。
除了手动控制的离合机构外，在一些实施例中，该离合机构还包括能够输出往复运动的驱动件，例如电机、气缸、液缸、电磁铁等。该驱动件的输出端与第一传动件3121和/或第二传动件配合，用于驱使第一传动件3121和/或第二传动件与对应的第一转轴316和/或第二转轴联动和解除联动。这种方式驱动件可根据使用者输入的指令控制离合机构，操作更为方便。
在一些实施例中可能采用扭矩限制离合器、过载离合器和超越离合器中的一种作为离合机构。此时，该第一转轴316和/或第二转轴通过对应的离合机构与第一传动件3121和/或第二传动件连接。一旦扭矩/转速超过置额定的扭矩/转速，传动件将不再随转轴转动。
 
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
