为了更美观和保护升降浮动组件，本实施例中，升降浮动组件5还 包括升降外壳54，升降外壳54与平面浮动组件4的移动端连接，具体与第二连杆42和第三连杆43之间的连杆转轴45固定连接，升降支架51、弹簧52和升降滑动块53均安装在升降外壳54内，升降外壳54面向连接件7的面上还设有开口，升降滑动块53穿过升降外壳54的开口与连接件7连接。
如图6所示，本实施例中，显示器3的下端安装有水平状的显示器转轴71，连接件7通过显示器转轴71与显示器3可旋转的连接，使得显示器3可相对连接件7上下摆动，医护人员可将显示器3上下摆动至合适的角度进行操作和查看。
在一种实施例中，底座转轴61、连杆转轴45和显示器转轴71中的一个或多个为阻尼转轴，阻尼转轴在转轴上设有阻尼辅助件，阻尼辅助件为起阻尼作用的拉簧、弹簧、扭簧或内部摩擦结构。阻尼转轴的设置，使得显示器3在平面浮动及翻转操作过程中能够任意停住，在无一定外力驱动的情况下显示器3将处于稳定的状态，以方便医生的使用。
在一种实施例中，为了对显示器3的平面浮动范围进行限定，以防止显示器3在误操作过程中移动至后方的设备或装置碰撞，限定在需要的一定范围内移动，使用更为便捷有效。
限位结构设置在底座转轴61、连杆转轴45和显示器转轴31上的一处或多处，如图7所示，以底座转轴61处的设置为例，在底座转轴61的上端设有弧形槽611，并设有与弧形槽611对应的限位销612，限位销612的一端固定在第一连杆41的第二安装部的通孔内和固定在第四连杆44的第一安装部的通孔内，限位销612的另一端可滑动的卡接在弧形槽611内，从而弧形槽611的弧度大小决定了第一连杆41和第四连杆44的转动角度范围，限位销612和弧形槽611配合限定了第一连杆41和第四连杆44相对底座6的旋转。
在其他实施例中，也可将弧形槽611设置在第一连杆41的第二安装部的通孔内和固定在第四连杆44的第一安装部的通孔内，限位销612固定在底座转轴61上，同样可实现限位效果。
在其他实施例中，如图7所示，弧形槽611设置在第一连杆41的第二安装部面向底座6的面上，限位销612安装在底座6上，同样可实现限位效果。同样，弧形槽611也可设置在底座6面向第一连杆41的第二安装部上，限位销612安装在第一连杆41的第二安装部上。
本实施例中，显示器3可通过平面浮动组件4实现相对控制面板2的前后水平移动。如图9所示，以显示器3向前移动为例进行说明，在初始状态下，平面浮动组件4的移动端贴合靠近固定端。显示器3向前移动过程中，第二连杆42的第一安装部和第三连杆43的第二安装部相对连杆转轴45旋转，在第二连杆42和第三连杆43的带动下，第一连杆41的第一安装部相对第二连杆42的第二安装部旋转，第四连杆44的第 二安装部相对第三连杆43的第一安装部旋转，同时第一连杆41的第二安装部和第四连杆44的第一安装部相对底座转轴61旋转，从而在四个连杆的旋转摆动下，平面浮动组件4的移动端逐渐远离固定端，显示器3的前后方向最大行程为平面浮动组件4的移动端和固定端之间的间距。
显示器3可通过平面浮动组件4实现相对控制面板2的左右水平移动。如图10所示，以显示器3从左向右移动为例进行说明，在初始状态下，第二连杆42、第四连杆44和显示器3均与平行设备的左右方向，平面浮动组件4的移动端位于固定端的左侧。显示器3向右移动的过程中，四个连杆的两端分别转动，相互间的转动关系和上述左右移动一致，不同之处在于各连杆两端的旋转角度不同，通过四个连杆的相互转动，使得保持平面浮动组件4的移动端与固定端之间的间距不变的情况下实现，显示器3从左端移动至右端，显示器3实现左右方向的平移。
显示器3可通过平面浮动组件4实现相对控制面板2的左右水平摆动。如图11所示，以显示器3从左侧偏转摆动至右侧偏转为例进行说明，在初始状态下，第二连杆42和第四连杆44平行设备的左右方向，显示器3朝左侧偏转。在水平摆动移动过程中，显示器3先摆动成朝前的方向，再摆动至朝右侧的方向，摆动期间，四个连杆的两端分别转动，相互间的转动关系和上述左右移动一致，不同之处在于各连杆两端的旋转角度不同。
除了上述几种移动方式以外，本实施例的显示器3可通过平面浮动组件4实现相对控制面板2的任意方向位置的移动，并移动停稳至移动范围内的任意位置，具体的移动方式和路线在此就不再赘述。
本实施例的显示器3还可以通过升降浮动组件5实现升降移动，并停稳在任意高度位置。
显示器3的升降原理动作为：以上升为例进行说明，外力驱动显示器3向上移动，显示器3将带动连接件5上移，连接件5将和升降滑动块53一通沿着升降支架51上的滑轨上移，升降滑动块53上移过程中带动弹簧52上移，而弹簧52的一端与升降支架51的底部固定连接，弹簧52被拉伸，弹簧52起到储能阻尼的作用，从而在弹簧52的作用下显示器3将停稳在上移后的位置；显示器3的下移动作与之相反，显示器3可停稳在升降范围内的任意高度位置。
一种实施例中，提供了一种超声诊断仪，本实施的超声诊断仪与上述实施例的区别在于升降浮动组件的结构不同。
如图12所示，本实施例的升降浮动组件8安装在底座6和平面浮动组件4之间。在其他实施例中，升降浮动组件8也可安装在平面浮动组件4和连接件7之间。
本实施例中，升降浮动组件8包括外立柱81、内立柱82和升降阻尼件，外立柱81为套筒结构，外立柱81安装在底座6或者直接安装在 控制面板2上，内立柱82可旋转和可升降的插装在外立柱81内，升降阻尼件安装在外立柱81和内立柱82之间，内立柱82的上端与平面浮动组件4的第一连杆41连接。外立柱81和内立柱82之间安装有升降阻尼件，升降阻尼件可为拉簧、弹簧、扭簧或内部摩擦结构，使得升降浮动组件8具有升降、旋转和任意停的功能。
升降浮动组件8通过内立柱82相对外立柱81上下移动实现显示器3的升降，并通过外立柱81和内立柱82之间升降阻尼件实现停留在升降过程的任意位置。
在其他实施例中，除了内外立柱的方案外，升降运动功能实现形式有很多种，如导轨滑动形式、滑轮滑轨形式、滑轮槽轨形式、直线导套形式、丝杠丝杆形式、链轮链条传动形式、同步带轮传动形式、滑轮绳索传动形式、齿轮齿条传动形式、连杆传动实现。为实现显示器3在升降任意位置停稳，其中具有升降功能的连杆可设计为带阻尼力平衡的升降连杆，形式也有很多种，如气弹簧形式、拉簧形式(含压簧形式)、恒力弹簧形式(如卷簧形式等)、扭簧形式、内部摩擦阻尼结构等。
一种实施例中，提供了一种超声诊断仪，本实施的超声诊断仪与上述实施例的区别在于升降浮动组件具有两个。
如图13所示，本实施例的升降浮动组件与上述升降浮动组件8的结构大体一致，本实施例的升降浮动组件也包括外立柱81、内立柱82和升降阻尼件。平面浮动组件4的两个中间端分别通过一个升降浮动组件连接，一个升降浮动组件安装在第一连杆和第二连杆之间，另一升降浮动组件安装在第三连杆和第三连杆之间。
具体的，一个外立柱81安装在第一连杆41的第一安装部的上端，一个内立柱82安装在第二连杆42的第二安装部的下端，与第二连杆42连接的内立柱82插装与第一连杆41连接的外立柱81上，并且外立柱81还设有升降阻尼件，从而第二连杆42可通过升降浮动组件相对第一连杆41升降移动。同样的，一个外立柱81安装在第四连杆44的第二安装部的上端，一个内立柱82安装在第三连杆43的第一安装部的下端，与第四连杆44连接的内立柱82插装与第三连杆43连接的外立柱81上，并且外立柱81还设有升降阻尼件，从而第三连杆43可通过升降浮动组件相对第四连杆44升降移动。
本实施例中，外立柱81和内立柱82可与连接的连杆为一体式结构，一体式结构的设计，提高了升降和平移的稳定性。
本实施例的显示器3在升降过程中，两个升降浮动组件将同时进行升降，以显示器3升降为例说明，显示器3向上移动后，显示器3将通过连接件7带动第二连杆42和第三连杆43上移，第二连杆42上移将带动与内立柱82相对外立柱81上移，同时第三连杆43将带动外立柱81相对内立柱82上移，第一连杆41和第四连杆44的高度位置不动，从而 在两个升降浮动组件的作用下，显示器3可实现升降移动，并且两个升降浮动组件的设计，优化了受力，从而提高了升降的稳定性。
一种实施例中，提供了一种超声诊断仪，本实施的超声诊断仪与上述实施例的区别在于升降浮动组件的结构不同。
如图14所示，本实施例中升降浮动组件9安装在平面浮动组件4和连接件7之间。
升降浮动组件9包括升降连杆91、固定块92和移动块93，升降连杆91的两端分别通过阻尼转轴与固定块92和移动块93可上下摆动的连接，固定块92与平面浮动组件4的移动端连接，移动块93与连接件7连接。本升降浮动组件9通过升降连杆91相对固定块92和移动块93的上下摆动实现升降功能，并且通过阻尼转轴实现任意停的功能。固定块92和移动块93可分别与平面浮动组件4的移动端和连接件7旋转连接，实现转动功能。
在其他实施例中，为实现显示器3在升降任意位置停稳，倾斜升降模块91还可设计为带阻尼力平衡的升降连杆，形式也有很多种，如气弹簧形式、拉簧形式(含压簧形式)、恒力弹簧形式(如卷簧形式等)、扭簧形式、内部摩擦阻尼结构等。
在其他实施例中，升降浮动组件9安装在平面浮动组件4的固定端和底座6之间，固定块92安装在底座6上，移动块93与平面浮动组件4的固定端连接，升降连杆91的两端分别与固定块92和移动块93铰接，相当于升降连杆91的两端与平面浮动组件4的固定端和底座6铰接，从而与平面浮动组件4连接的显示器3可通过升降连杆91实现相对底座6摆动式的升降。斜升降连杆91通过上述带阻尼力平衡的设计，使得显示器3在升降过程中可挺稳在任意位置。
在其他实施例中，不同结构的平面浮动组件和不同结构的升降浮动组件可任意组合，形成空间浮动装置。
一种实施例中，如图15a至图15c所示，升降浮动组件9包括升降连杆91、固定块92、移动块93、传动轮94和传动带95，升降连杆91为一根直杆，固定块92和移动块93的一端设有用于旋转连接的连接孔，另一端设有两块间隔开的安装板，两个安装板之间安装有转轴，斜升降连杆91的两端分别与在固定块92和移动块93上的转轴固定连接。
本实施例中，传动轮94为齿轮，传动带95为链条，在其他实施例中，传动轮94也可为同步轮、皮带轮等，传动带95也可为与传动轮94对应匹配的同步带、皮带等。
本实施例中，传动轮94具有两个，分别安装在固定块92和移动块93上的转轴上。传动带95连接在两个传动轮94之间，斜升降连杆91的两端相对固定块92和移动块93转动时，传动带95将被传动轮94带着转动，传动轮94和传动带95将起到稳定升降的作用。
本升降浮动组件9上增加了传动轮94和传动带95，传动轮94或传动带95可与驱动装置连接，驱动装置驱动通过驱动传动轮94和传动带95带动升降连杆91相对固定块92和移动块93旋转，从而实现升降移动，并且可保证移动块93在升降过程中处于水平状态。
一种实施例中，如图16a至图16c所示，升降浮动组件9包括升降连杆91、固定块92、移动块93和绳索96，其中固定块92和移动块93与上述实施例的结构相同，固定块92和移动块93的一端具有用于旋转连接的连接孔，另一端设有两块间隔开的安装板，两个安装板之间安装有转轴。升降连杆91为一个直杆，并且中部具有凸起部91a，凸起部91a的顶端设有滑槽91b，绳索96的两端分别固定在固定块92和移动块93上，并且可与升降连杆91的交接点错开设置，绳索96的中部可滑动的勒紧在升降连杆91的滑槽91b内，升降连杆91的凸起部91a将绳索96顶起形成预紧的效果，并且绳索96可相对升降连杆91的凸起部91a滑动，从而在升降连杆91的两端相对固定块92和移动块93转动时，绳索96将相对升降连杆91滑动，起到稳定升降的作用。
本升降浮动组件9上增加了绳索96，绳索96可与驱动装置连接，驱动装置驱动通过绳索96带动升降连杆91相对固定块92和移动块93旋转，从而实现升降移动，并且可保证移动块93在升降过程中处于水平状态。
一种实施例中，如图14和图17所示，升降浮动组件9包括升降连杆91、固定块92、移动块93、角度检测装置和驱动锁定装置，其中升降连杆91、固定块92和移动块93和上述结构一致，升降连杆91的两端分别通过转轴与固定块92和移动块93铰接，升降连杆91与固定块92和移动块93的铰接点为O1和O2。角度检测装置具有两个检测端，角度检测装置的两个检测端分别安装在升降连杆两端的铰接处，分别用于检测升降连杆91两端铰接点O1和O2处的角度值θ1和θ2，并且角度检测装置将检测到的角度信号传输给驱动锁定装置，驱动锁定装置具有两个输出端，两个输出端分别与升降连杆91两端的转轴连接，驱动锁定装置的两个输出轴可分别异步输出，并且在不工作时具有锁定的作用。在升级过程中，驱动锁定装置将驱动升降连杆91两端的转轴各种旋转特定的角度，并实时通过角度检测装置检测升降连杆91两端的摆动角度，角度检测装置的检测信号反馈给驱动锁定装置，驱动锁定装置再调整驱动摆动角度大小，驱动锁定装置可根据程序设置，保证在任意升级过程中，移动块93始终与固定块92平行，保证了升降过程中显示器3的平稳。
在其他实施例中，驱动锁定装置仅包括驱动作用，在升降连杆91两端的转轴处分别安装有锁定装置，锁定装置用于锁紧升降连杆91的两端的旋转，从而锁紧了升降活动，将显示器3停稳在所需的水平高度位 置。
一种实施例中，如图18a和图18b所示，升降浮动组件100包括固定块101、移动块102、第一升降连杆103、第二升降连杆104、第三升降连杆105和滑套106。升降浮动组件100安装在平面浮动组件4和连接件7之间，也可安装在底座6和平面浮动组件4之间；具体的，固定块101与平面浮动组件4的移动端连接，移动块102与连接件7连接，或者，固定块101与底座6连接，移动块102与平面浮动组件4的固定端连接。
第一升降连杆103和第二升降连杆104的两端分别铰接在固定块101和移动块102上，并且第一升降连杆103和第二升降连杆104平行设置。滑套106包括滑块106a和摩擦套106b，滑块106a由四个板围合围成，中间为镂空结构，滑块106a的四个面上均设有通孔，摩擦套106b由橡胶等具有一定摩擦力的材质制成，摩擦套106b通过套环固定在滑块106a的两个相对的通孔之间，滑块106a和摩擦套106b一同可移动的套设在第二升降连杆104上，并靠近固定块101设置，摩擦套106b与第二升降连杆104之间将产生一定摩擦力，该摩擦力起到阻尼的作用。第三升降连杆105具有两个，两个第三升降连杆105的两端分别与固定块101和滑块106a铰接，两个第三升降连杆105位于滑块106a的两侧，第三升降连杆105可与第一升降连杆103通过相同的转轴铰接在固定块101上。
本实施例的升降阻尼原理为，当移动块102上移时，带动第一升降连杆103和第二升降连杆104的两端旋转分别相对固定块101和移动块102转动，第一升降连杆103和第二升降连杆104与移动块102连接的移动向上摆动，第二升降连杆104向上摆动后，由于滑套106被第三升降连杆105拉住，故滑套106相对第二升降连杆104将滑动并产生摩擦力；移动块102停留在一定高度后失去牵引力，移动块102以及与之连接的部件将产生一个向下的重力，重力将驱使第一升降连杆103和第二升降连杆104向下摆动，此时，滑套106相对第二升降连杆104将产生一个向上的摩擦力，该摩擦力大于移动块102以及与之连接的部件产生的重力时，将起到阻尼限位的作用。选用能够起到足够摩擦力的摩擦套106b可实现任意停的功能，本实施例的摩擦套106b长度和材料根据实验优化设计，使得升降浮动组件100能够挺稳在任意高度位置。
本实施例中，还在第二升降连杆104上设置有弹簧107，为了限位弹簧107，第二升降连杆104上在靠近移动块102的一端设有挡片108，弹簧107被夹在挡片108和滑块106a之间，弹簧107起到缓冲储能的作用，在移动显示器3升降的过程中，可通过弹簧107存储的能量克服滑套106与第二升降连杆104之间的摩擦力，从而通过较小的外力可驱动升降，方便了使用者的操作。挡片108也设置成螺母，第二升降连杆104 设有对应的外螺纹，挡片108可沿着第二升降连杆104移动，可移动的挡片108可调节弹簧107的挤压量，从而可根据实现需要调节弹簧107的松紧度，以实现最佳的升降移动。
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。
