背景技术
[0002] 医护人员在使用带有控制面板的医疗仪器吋 (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査吋, 要求控制面板能够运 动灵活, 即控制面板可以实现上下升降、 前后移动、 左右移动, 左右转动等操 作 (全浮动操作) , 这就要求控制面板浮动装置具备这样的功能。
[0003] 通常的控制面板浮动结构有两种方式: 第一种是独立的升降结构 (竖直面内) 加独立的前后平动和转动结构 (水平面内) 。 这种浮动结构的升降、 前后移动 和旋转分别由两套独立的机构实现, 其升降结构占用主机空间大。 另一种是独 立的升降结构 (竖直面内) 加独立的青蛙腿结构方式 (水平面内) , 青蛙腿结 构是一种变形的平行四连杆结构, 其固定端由两个转动的支点形成, 以带动四 个移动臂, 控制面板固定在两个移动臂的端部, 如此实现一定范围内的前后平 移、 左右平移和旋转功能。 这种浮动结构的升降动作和水平面内的平移及转动 需单独操作, 没有联动性。

[0089] 其中, 第二连接座 322通过第三转动副连接到第一连接座 314上, 并可以通过第 三转动副相对于所述第一连接座 314绕第三转动轴线 C转动。 第二连接臂 327的一 端通过第四转动副连接到第二连接座 322上, 并可以通过第四转动副相对于第二 连接座 322绕第四转动轴线 D转动。 第二连接臂 327的另一端通过第五转动副连接 到第二支承座 324上, 并可以通过第五转动副相对于第二支承座 324绕第五转动 轴线 E转动。
[0090] 如此, 第二连接座 322、 第二连接臂 327和第二支承座 324之间就形成了一个可 以升降的结构, 使得第二支承座 324可相对于第二连接座 322完成升降动作。 再 配合上第一支承座 312、 第一连接臂 317和第一连接座 314之间的升降结构以及第 二连接座 322与第一连接座 314之间的转动结构, 使得该浮动机构 300可以实现更 多方位的移动。 而且该浮动机构的升降结构和转动结构设计为一体联动, 因此 联动性好, 响应迅速, 且占用空间小, 操作范围大。
[0091] 前述的实施例中, 第一连接臂 317和第二连接臂 327可以是由杆状部件形成的单 个元件, 例如可以是连杆; 或者, 也可以是由多个部件形成的元件。 例如, 请 参考图 5, 在某些实施例中, 该第一连接臂 317可以包括第一上支架 311和第一下 支架 313。 同理, 在某些实施例中, 该第二连接臂 327可以包括第二上支架 321和 第二下支架 323。 当然, 第一连接臂 317和第二连接臂 327也可以采用其他形式的 结构。
[0092] 进一步地, 上述各零部件之间建立转动副实现转动连接, 该转动副 (也包括本 实施例其他转动副结构) 可以是任何适合的转动副机构, 例如, 可以是由限位 销和销孔形成的转动副, 也可以是旋转座和旋转轴形成的转动副等。 一些转动 副的具体的结构的实例将在下文中参考附图进行详细描述。 但是, 容易理解, 前述的转动副的结构将不限于下文中详细说明的实例。
[0093] 进一步地, 请参考图 4, 在一些更具体地实施例中, 第一转动轴线 A和第二转动 轴线 B相互平行, 从而使得第一连接臂 317分别相对于第一支承座 312和第一连接 座 314的转动运动在同一平面或平行的平面内, 以便于减少两处转动运动相互干 涉, 使两处转动能够很好的叠加, 产生更丰富的位置变化。
[0094] 进一步地, 请参考图 4, 在一些更具体地实施例中, 第四转动轴线 D和第五转动 轴线 E相互平行, 从而使得第二连接臂 327分别相对于第二支承座 324和第二连接 座 322的转动运动在同一平面或平行的平面内, 以便于减少两处转动运动相互干 涉, 使两处转动能够很好的叠加, 产生更丰富的位置变化。
[0095] 进一步地, 请参考图 3和 4, 在一些更具体地实施例中, 第三转动轴线 C与第二 转动轴线 B相互垂直, 从而使得第二连接座 322在第一连接座 314上的转动运动与 第一连接座 314相对于第一支承座 312的升降运动是垂直的, 以便于减少升降运 动和转动运动的相互干涉, 保证浮动机构的浮动运动更易操作, 更容易行走到 目的位置。
[0096] 在一些更具体地实施例中, 第三转动轴线 C与第四转动轴线 D相互垂直 (可以 理解, 此吋, 第四转动轴线 D与第二转动轴线 B可以是相互平行的或者不平行的 ) , 从而使得第二连接臂 327在第二连接座 322上的升降运动与第二连接座 322相 对于第一连接座 314的转动运动是垂直的, 以便于两处升降运动的叠加, 减少各 个转动运动之间的干涉, 保证浮动机构的浮动运动更易操作, 更容易行走到目 的位置。 [0097] 本文中, 当提及两条转动轴线 "相互垂直"吋, 可以指的是: 当这两条转动轴线 在同一平面内吋, 二者相互垂直; 当这两条转动轴线不在同一平面内吋, 二者 在空间上相互垂直, 即其中一条转动轴线在另一条转动轴线所在的平面上的投 影与该另一条转动轴线相互垂直。
[0098] 本文中, 当提及两条转动轴线 "相交 "吋, 可以指的是: 当这两条转动轴线在同 一平面内吋, 二者彼此相交; 当这两条转动轴线不在同一平面内吋, 其中一条 转动轴线在另一条转动轴线所在的平面上的投影与该另一条转动轴线彼此相交
[0099] 第一支承座 312也可以与第一部件是转动连接。 例如, 请参考图 3和 4, 在一种 实施例中, 第一支承座 312通过第六转动副连接到第一部件 (图中所示为主机 10 0) 上, 并可以通过第六转动副相对于第一部件绕第六转动轴线 F转动。 采用绕 第六转动轴线 F的转动结构, 可以使得在第一部件和第二部件之间增加了更多的 自由度, 因此第一部件相对于第二部件可以有更多的位置变化和移动路径。
[0100] 请参考图 3和 4, 在一些更具体地实施例中, 第六转动轴线 F与第三转动轴线 C相 互平行, 这样的设计使得第一支承座 312在第一部件上的转动方向与第一连接座 314和第二连接座 322的转动方向在同一平面或平行, 以便于减少两处转动运动 的相互干涉, 使得两者的转动可以最大化的叠加, 起到更好的转动效果, 产生 更丰富的位置变化。
[0101] 第二支承座 324也可以与第二部件是转动连接。 例如, 请参考图 1、 3和 4, 在一 种实施例中, 第二支承座 324通过第七转动副连接到第二部件 (图 1所示第二部 件为控制面板 200, 例如可以是连接到固定座 340, 从而通过固定座 340连接到控 制面板 200) 上, 并可以通过第七转动副相对于第二部件绕第七转动轴线 G转动 。 采用绕第七转动轴线 G转动的结构, 可以使得在第一部件和第二部件之间增加 了更多的自由度, 因此第一部件相对于第二部件可以有更多的位置变化和移动 路径。
[0102] 请参考图 3和 4, 在一些更具体地实施例中, 第七转动轴线 G与第三转动轴线 C 相互平行。 这样的设计使得第二支承座 324在第二部件上的转动方向与第一连接 座 314和第二连接座 322的转动方向在同一平面或平行, 以便于减少两处转动运 动的相互干涉, 使得两者的转动可以最大化的叠加, 起到更好的转动效果, 产 生更丰富的位置变化。 如果再叠加上第一支承座 312在第一部件上的转动运动, 这种位置变化将更加丰富。
[0103] 如前文所述, 本申请的实施例中, 浮动机构 300可以包括一组或者多组如前文 所述的连杆组件。 这些实施例中, 各组连杆组件各自的第一支承座可以是分离 的单独的元件, 也可以形成为同一个元件; 和 /或, 各组连杆组件各自的第二支 承座可以是分离的单独的元件, 也可以形成为同一个元件。
[0104] 前述的各个实施例中, 各组连杆组件各自的第一支承座与第一部件的连接位置 之间可以相距预定的距离, 也可以大体上在相同的位置; 和 /或, 各组连杆组件 各自的第二支承座与第二部件的连接位置之间可以相距预定的距离, 也可以大 体上在相同的位置。
[0105] 例如, 一些实施例中, 浮动机构 300可以包括第一组连杆组件和第二组连杆组 件, 每组连杆组件可以均具有如前文所述的实施例中的连杆组件的结构, 该结 构在此不再赘述。
[0106] 参考图 22的示意图, 第一组连杆组件的第二支承座和第二组连杆组件的第二支 承座可以为分离的元件。 第一组连杆组件的第二支承座在第一连接位置 201处连 接到第二部件 200, 第二组连杆组件的第二支承座在第二连接位置 202处连接到 第二部件 200, 并且第一连接位置 201和第二连接位置 202之间相距预定的距离。 即, 第一组连杆组件的第二支承座和第二组连杆组件的第二支承座相距预定的 距离连接到第二部件 200。
[0107] 前述实施例中, 第一组连杆组件的第三转动轴线可以与第二组连杆组件的第三 转动轴线相互平行。 这样, 可以使得两组连杆组件中的第二连接座基于第三转 动副相对于第一连接座的转动在平行或者重合的平面内进行, 从而减少两处转 动运动的相互干涉, 提高该两组连杆组件和第一部件及第二部件组成的运动系 统的整体操控性。
[0108] 前述实施例中, 第一组连杆组件的第六转动轴线可以与第二组连杆组件的第六 转动轴线相互平行。 这样, 可以使得两组连杆组件中的第一支承座基于第六转 动副相对于第一部件的转动在平行或者重合的平面内进行, 从而减少两处转动 运动的相互干涉, 进一步提高该两组连杆组件和第一部件及第二部件组成的运 动系统的整体操控性。
[0109] 前述实施例中, 第一组连杆组件的第七转动轴线可以与第二组连杆组件的第七 转动轴线相互平行。 这样, 可以使得两组连杆组件中的第二支承座基于第七转 动副相对于第二部件的转动在平行或者重合的平面内进行, 从而减少两处转动 运动的相互干涉, 进一步提高该两组连杆组件和第一部件及第二部件组成的运 动系统的整体操控性。
[0110] 参考图 22的示意图。 与浮动机构只包含一组连杆组件的实施例相比, 在这些实 施例中, 由于第一组连杆组件的第二支承座和第二组连杆组件的第二支承座相 距预定的距离连接到第二部件, 因此第一组连杆组件、 第二组连杆组件和第二 部件成了一个闭合的系统 (如图 22中的五边形所示) 并且第二部件本身成为该 闭合系统中的一个环节 (例如, 如图 22所示, 控制面板 200 (作为第二部件示例 ) 为表示该闭合系统的五边形的一条边) , 而该闭合系统中的其余环节 (例如 , 图 22中的五边形的其他几条边) 为耦合结构, 即它们之间的运动是相互影响 的。 因此, 当操作第二部件相对于第一部件运动吋, 运动的指向性将与操作方 向一致, 操作性能更好。
[0111] 类似地, 第一组连杆组件的第一支承座和第二组连杆组件的第一支承座也可以 为分离的元件并且相距预定的距离连接到主机 100 (作为第一部件示例) , 从而 具有前述类似的优点。
[0112] 进一步地, 请参考图
1-4, 在一种实施例中, 该浮动机构 300包括第一升降结构 310和第二升降结构 320 。 该第一升降结构 310用于安装到第一部件上, 同吋第一升降结构 310具有能够 使其一端相对第一部件在竖直方向上做升降运动的升降结构。 这种升降结构可 驱使第一升降结构 310至少一端在竖直平面内相对第一部件做升降运动。
[0113] 该第二升降结构 320用于支撑第二部件, 该第二升降结构 320的一端转动连接在 第一升降结构 310上, 该第二升降结构 320的另一端能够相对第一升降结构 310在 竖直方向上做升降运动。
[0114] 其中, 第一升降结构 310和第二升降结构 320用以实现升降运动的升降结构可以 相同, 也可以不同。
[0115] 同吋, 由于第二升降结构 320转动连接在第一升降结构 310上, 使得第二升降结 构 320可相对第一升降结构 310在垂直于两者旋转中心线的平面内转动, 同吋加 以竖直方向上的升降运动, 使得该浮动机构 300可以实现更多方位的移动。
[0116] 此外, 第一升降结构 310和第二升降结构 320各自具备独立的升降功能, 使得浮 动机构 300的位置变化更灵活多变。 另一方面, 本浮动机构 300中升降结构和转 动结构设计为一体联动, 因此联动性好, 响应迅速, 且占用空间小, 操作范围 大。
[0117] 请继续参考图 1-4, 在一种实施例中, 第一升降结构 310和第二升降结构 320均 为两个, 一个第一升降结构 310对应与一个第二升降结构 320转动连接组成一组 连杆组件, 两组连杆组件中两个第一升降结构 310用于与第二升降结构 320连接 的连接端以相互靠近或远离的方式设置。
[0118] 其中, 两个第一升降结构 310与主机 100连接, 两个第二升降结构 320用于支撑 控制面板 200。
[0119] 当然, 在其他实施例中, 浮动机构 300也可能仅依靠一组连杆组件, 即一个第 一升降结构 310和一个第二升降结构 320实现浮动功能, 或者也可能依靠两组以 上的第一连接臂和一个第二连接臂来实现浮动功能, 从而进一步保证第一部件 和第二部件之间的连接和支撑的稳定性和平衡性。 具体数量在本实施例所公幵 内容的指导下可根据实际需求灵活选定。 当第一部件和第二部件之间设有多个 浮动机构 300吋, 各个浮动机构 300可以是相互分离的或独立的, 也可以是共用 的或者部分共用的。
[0120] 在一些实施例中, 为了实现升降功能, 第一升降结构 310和第二升降结构 320可 以设计成四连杆结构, 例如设计成平行四边形结构或者其他四连杆结构。
[0121] 在一种实施例中公幵了第一升降结构 310和第二升降结构 320的一种示例结构。
具体地, 请参考图 4-6, 该第一升降结构 310包括第一上支架 311、 第一支承座 312 、 第一下支架 313和第一连接座 314。 该第一上支架 311、 第一支承座 312、 第一 下支架 313和第一连接座 314依次首尾转动连接形成平行四边形结构 (或其他形 式的四连杆结构) , 该第二升降结构 320转动连接在第一连接座 314上。 [0122] 具体地, 该第一上支架 311相对的两端通过各自的销轴转动连接于第一支承座 3 12与第一连接座 314之间, 第一下支架 313相对的两端分别通过各自的销轴转动 连接于第一支承座 312与第一连接座 314之间, 第一上支架 311与第一下支架 313 相对平行设置, 从而形成一个平面内的平行四边形结构, 四个转动副分别在平 行四边形的四个顶点位置, 使得该第一连接座 314能够在第一上支架 311和第一 下支架 313的作用下相对第一支承座 312升降。
[0123] 进一步地, 请继续参考图 4-6, 在一种实施例中, 第二升降结构 320也采用类似 第一升降结构 310的结构。 具体地, 该第二升降结构 320包括第二上支架 321、 第 二连接座 322、 第二下支架 323和第二支承座 324, 该第二上支架 321、 第二连接 座 322、 第二下支架 323和第二支承座 324依次首尾转动连接形成平行四边形结构 (或其他形式的四连杆结构) , 该第二连接座 322转动连接在第一升降结构 310 的第一连接座 324上。
[0124] 具体地, 该第二上支架 321相对的两端通过各自的销轴转动连接于第二连接座 3 22与第二支承座 324之间, 第二下支架 323相对的两端分别通过各自的销轴转动 连接于第二连接座 322与第二支承座 324之间, 第二上支架 321与第二下支架 323 相对平行设置, 从而形成一个平面内的平行四边形结构, 四个转动副分别在平 行四边形的四个顶点位置, 使得该第二支承座 324能够在第二上支架 321和第二 下支架 323的作用下相对第二连接座 322升降。 该第二连接座 322可安装在第一连 接座 314上, 使得第一连接座 314的升降运动能够带动整个第二升降结构 320做升 降运动。
[0125] 以上平行四边形结构通常可以通过增加转动副处的摩擦力实现在某一位置的平 衡, 进而将浮动机构 300停止在需要的位置上。 当然, 为了进一步提高平行四边 形结构的稳定性, 在一些实施例中, 还可以增设阻尼平衡补偿系统。
[0126] 请参考图 7, 该阻尼平衡补偿系统 360设置于第一升降结构 310和 /或第二升降结 构 320所形成的四连杆结构的收容空间 370内, 用于补偿因第一升降结构 310转动 一定角度导致的作用于第一升降结构 310的力矩的变化, 使作用于第一升降结构 310的力矩保持平衡, 进而能平稳支撑控制面板 200及显示器 400。
[0127] 请参考图 6和 7, 阻尼平衡补偿系统 360收容于收容空间 370内, 其包括导杆 361 、 导筒 362以及弹簧 363。 导筒 362包括幵口端 3621以及第一连接端 3622。
[0128] 第一连接端 3622通过销轴 365与第一支承座 312连接。 幵口端 3621向内凹陷形 成收容空间 370。 导杆 361包括第二连接端 3611、 第一延伸端 3612以及第二延伸 端 3613。 第二连接端 3611通过销轴 366与第一上支架 311转动连接, 且第二连接 端 3611远离第一连接座 314
的末端凸出延伸形成第一延伸端 3612。 第一延伸端 3612远离第二连接端 3611的 一端继续凸出延伸形成第二延伸端 3613。 其中, 第二连接端 3611、 第一延伸端 3 612以及第二延伸端 3613的尺寸依次减小, 从而使导杆 361形成三级阶梯状。
[0129] 第二延伸端 3613通过幵口端 3621伸入导筒 362的收容空间 370中, 并可在收容 空间 370内相对于导筒 362沿轴向方向移动。 第二延伸端 3613外套设有与收容空 间 370的内表面抵压接触的摩擦垫 364。 摩擦垫 364的一端抵接于第二延伸端 3613 与第一延伸端 3612连接处, 另一端通过固定螺母固定于第二延伸端 3613远离第 一延伸端 3612的末端, 防止其脱落。
[0130] 弹簧 363套设于导杆 361与导筒 362外, 且导杆 361与导筒 362沿轴向从弹簧 363 中间穿过。 具体地, 导杆 361的第二连接端 3611外凸设有法兰 3614, 导筒 362的 第一连接端 3622外螺接有弹簧调节螺母。 弹簧 363抵接于法兰 3614与弹簧调节 螺母之间。 此吋, 弹簧 363对导杆 361产生一定推力, 且操作者可以通过调节弹 簧调节螺母与法兰 3614之间的距离, 以调节弹簧 363对导杆 351产生的推力的大 小, 该弹簧 363的推力就可以对第一升降结构 310 (或第二升降结构 320) 起到平 衡的作用。
[0131] 超声诊断仪在工作中需要转动浮动机构 300使控制面板 200向上或向下运动转动 一个角度。 在某些情况下, 转动到新的位置后, 弹簧 363的长度会发生变化, 也 就是弹簧 363的压缩量会发生变化, 此吋可能第一上支架 311无法将控制面板 200 和显示器 400稳定支撑在期望的位置。
[0132] 本实施例的结构可以对这种力矩变化进行补偿。 如图 7所示, 本实施例中, 导 杆 361的第二延伸端 3613上套设有摩擦垫 364, 摩擦垫 364与导筒 362
的收容空间 370的内表面抵压接触。 当在新的位置, 第一上支架 311有向下转动 的趋势, 此吋, 第一上支架 311向下运动的趋势带动导杆 361有沿轴向向导筒 362 运动的趋势, 也就是导杆 361有向导筒 362内深入运动的趋势。 此吋, 由于导杆 3 61的第二延伸端 3613处套设的摩擦垫 364与导筒 362的内表面抵压接触, 因此, 摩擦垫 364与导筒 362内表面将产生静摩擦力。 由于导杆 361与第一上支架 311连 接, 因此摩擦力将作用在第一上支架 311上, 如此, 摩擦力的力矩可以使得作用 于第一上支架 311的力矩仍然保持平衡, 从而将浮动就 300停留在理想的位置。
[0133] 在实施例中, 通过弹簧 363的作用力平衡第一上支架 311所受的力矩, 并通过导 杆 361上设置的摩擦垫 364与导筒 362内表面的静摩擦力对第一上支架 311所受的 力矩进行进一步的补偿平衡, 从而使第一上支架 311可以在任意位置保持平衡, 而且在弹簧力值衰减的情况下, 也可补偿弹簧力值的衰减, 使第一上支架 311保 持平衡, 从而对控制面板 200和显示器 400提供稳定支撑。 可以理解地, 在其它 一些实施例中, 该阻尼补偿系统 360还可以有其他的实现方式, 在此不作限定。 例如, 采用气弹簧、 拉簧、 扭簧等结构形式。
[0134] 以上只是第一升降结构 310和第二升降结构 320的一种示例性结构, 当然, 第一 升降结构 310和第二升降结构 320完全可以采用不同的升降结构。 而实现第一升 降结构 310和第二升降结构 320升降运动的升降结构也可以采用如电机驱动等其 他能够实现升降功能的结构。
[0135] 在整个浮动机构 300中, 第二支承座 324的升降运动是第一升降结构 310和第二 升降结构 320各自升降运动的合成, 其移动轨迹更为丰富多变。 同吋, 第二连接 座 322与第一连接座 314采用转动连接, 使得第一升降结构 310与第二升降结构 32 0之间能够相对转动, 这种转动结合升降运动, 使得安装在第二支承座 324上的 第二部件能够相对安装在第一支承座 312上的第一部件有着非常丰富的方位变化
[0136] 进一步地, 第一升降结构 310和第二升降结构 320通过建立转动副实现转动连接
, 该转动副 (也包括本实施例其他转动副结构) 可以是任何适合的转动副机构 , 例如, 可以是由限位销和销孔形成的转动副, 也可以是旋转座和旋转轴形成 的转动副, 等等。 一些转动副的具体的结构的实例将在下文中参考附图进行详 细描述。 但是, 容易理解, 前述的转动副的结构将不限于下文中详细说明的实 例。 [0137] 请参考图 5、 6、 8, 在一种实施例中, 第一连接座 314的一端凸出形成有第一凸 耳 3141。 第一凸耳 3141由第一连接座 314背向第一上支架 311和第一下支架 313的 一侧边缘呈弧形延伸而成, 且其上幵设有用以与对应第二升降结构 320转动连接 的第一轴孔 3142, 第二升降结构 320安装在第一轴孔 3142处, 并通过第一转动轴 351连接于一体。
[0138] 请参考图 4, 在一种实施例中, 两个第一连接座 314上的两个第一凸耳 3141以向 相互靠近的内括方式弯曲而成, 从而使两个安装座 330、 两组连杆组件以及固定 座 340之间的连线为六边形, 此处所说的六边形不仅包括通常所认识的位于同一 平面内的六边形, 也包括空间范围内的六边形。 该空间范围内的六边形的边可 以位于不同平面内, 例如图 16a和 16b所示。 在其它一些实施例中, 两个第一凸耳 3141亦可以向相互远离的外括方式弯曲而成, 在此不作限定。
[0139] 另一方面, 为了限制连接座第一连接座 314和第二连接座 322之间的相对转动角 度, 可以使连接座第一连接座 314和第二连接座 322中至少其一设有围绕两者之 间的旋转中心线呈弧形分布的第一限位槽, 而该连接座第一连接座 314和第二连 接座 322中对应的另一个则设置有第一限位销, 第一限位销与第一限位槽配合, 限制连接座第一连接座 314和第二连接座 322的相对转动角度。 即当连接座第一 连接座 314设置有第一限位槽吋, 第一限位销设置在第二连接座 322上; 当第二 连接座 322设置有第一限位槽吋, 第一限位销设置在连接座第一连接座 314上; 当连接座第一连接座 314和第二连接座 322同吋设有第一限位槽吋, 连接座第一 连接座 314和第二连接座 322同吋也设有第一限位销, 用以与第一限位槽配合。
[0140] 具体地, 请参考图 8, 在一种实施例中, 该第一凸耳 3141上幵设有弧形第一限 位槽 3143。 第一限位槽 3143沿周向包围于第一轴孔 3142的外围, 即围绕第一连 接座 314和第二连接座 322之间的旋转中心线设置, 用于限定第二升降结构 320相 对于第一升降结构 310的转动角度。 请参考图 5和 8, 装配吋, 该第二升降结构 32 0的第二连接座 322通过第一转动轴 351安装在第一升降结构 310的第一轴孔 3142 处, 同吋第一限位销 3144与第二连接座 322固定连接, 一体联动。 并且第一限位 销3144—端嵌入到第一限位槽 3143内, 并被限制在第一限位槽 3143内活动, 从 而对第二连接座 322的转动角度形成限位。 [0141] 另一方面, 浮动机构 300包括安装座 330。 安装座 330用于安装在需要使用浮动 机构 300的基座上。 在本具体实施例中, 基座为超声诊断仪的主机 100, 在其他 实施例中, 基座还可以是各种需要使用浮动机构 300的平台或者其他支撑或者连 接结构。
[0142] 为了使浮动机构 300获得更多方位的浮动, 在一种实施例中, 使第一升降结构 3 10转动连接在安装座 330上, 使得第一升降结构 310和第二升降结构 320可以整体 相对安装座 330转动, 进而与上述其他运动合成为更丰富的变化。
[0143] 第一升降结构 310与第二升降结构 320相对的一端通过转动副可转动地连接于安 装座 330上。 第二升降结构 320通过转动副可转动地连接到第一升降结构 310远离 安装座 330的一端。
[0144] 一种实施例中, 第一升降结构 310相对安装座 330的旋转中心线与第一升降结构 310的升降运动方向一致, 使得第一升降结构 310能够在与安装座 330的旋转中心 线垂直的平面内平移, 这个平面通常情况下可设置为水平面。
[0145] 当然, 在其他实施例中, 第一升降结构 310相对安装座 330的旋转中心线与第一 升降结构 310的升降运动方向成一定的角度, 使得第一升降结构 310可以在与其 升降方向成一定角度的平面内转动。
[0146] 请参考图 6, 在一种实施例中, 第一升降结构 310的一端通过转动副可转动地连 接于安装座 330上, 并以第一升降结构 310与安装座 330的连接点为轴转动。 第二 升降结构 320可转动地连接到第一升降结构 310, 从而安装座 330可以带动第一升 降结构 310并由此带动第二升降结构 320以安装座 330为支点于所限定的平面内旋 转。
[0147] 而在某些对浮动机构 300自由度数量要求较小的环境下, 第一升降结构 310也可 以与安装座 330为固定连接, 或者第一升降结构 310直接固定在第一部件上。
[0148] 进一步地, 为了实现安装座 330和第一升降结构 310的转动连接, 在一种实施例 中, 安装座 330和第一支承座 312中至少其一设有第二轴孔, 而安装座 330和第一 支承座 312中对应的另一个则设置有第二转动轴, 该第二转动轴与第二轴孔配合 , 使得第一支承座 312能够相对安装座 330转动。 即当安装座 330设置有第二轴孔 吋, 第二转动轴 331设置在第一支承座 312上; 当第一支承座 312设置有第二轴孔 吋, 第二转动轴 331设置在连接座第一连接座 314上; 当连接座第一连接座 314和 第二连接座 322同吋设有第二轴孔吋, 连接座第一连接座 314和第一支承座 312同 吋也设有第二转动轴 331, 用以与第二轴孔配合。
[0149] 具体地, 请继续参考图 6, 第二转动轴 331设置在安装座 330上, 第二轴孔 (图 中未标示出) 设置在第一支承座 312上, 第一支承座 312倒扣在第二转动轴 331上 。 第二转动轴 331大体呈圆柱形, 其固定安装于主机 100上。 第一支承座 312大 体为一端幵口的中空圆柱形, 第二轴孔位于圆柱形的中部, 其通过幵口端转动 套设于第二转动轴 331外。 这样, 第二转动轴 331与第一支承座 312之间的配合构 成转动副结构。
[0150] 进一步, 为了限定第一支承座 312相对安装座 330的转动角度, 在一种实施例中 , 安装座 330和第一支承座 312中至少其一设有围绕两者之间的旋转中心线呈弧 形分布的第二限位槽, 而安装座 330和第一支承座 312中对应的另一个则设置有 第二限位销, 第二限位销与第二限位槽配合, 限制安装座 330和第一支承座 312 的相对转动角度。 即当安装座 330设置有第二限位槽吋, 第二限位销设置在第一 支承座 312上; 当第一支承座 312设置有第二限位槽吋, 第二限位销设置在连接 座第一连接座 314上; 当连接座第一连接座 314和第二连接座 322同吋设有第二限 位槽吋, 连接座第一连接座 314和第一支承座 312同吋也设有第二限位销, 用以 与第二限位槽配合。
[0151] 请参考图 9, 一种更为具体的实施例中, 第二限位槽 3311设置在第二转动轴 331 的表面上, 而第二限位销 3312穿过第二轴孔的孔壁并嵌于第二限位槽 3311内, 以限制第一支承座 312相对于第二转动轴 331的转动角度。
[0152] 在其它一些实施例中, 安装座 330亦可为安装于主机 100顶部的一个, 两个第 一升降结构 310分别转动安装于一个安装座 330相对的两侧。 安装座 330的旋转 结构可以根据需要而设计, 只需实现其可在外力作用下带动对应连杆组件中第 一升降结构 310与第二升降结构 320相对于机架在平面内旋转的功能即可, 在此 不作限定。 例如, 将第二转动轴 331可转动地安装于主机 100上, 并将第一支承 座 312套设于第二转动轴 331以随第二转动轴 331—同相对于主机 100旋转; 或者 直接将第二转动轴 331与第一支承座 312—体设计为一个整体的转动元件, 其直 接可转动地安装于主机 100上亦可。
[0153] 请返回参考图 6, 在一种实施例中, 安装座 330还包括设置于第二转动轴 331与 第一支承座 312之间的衬套 332, 衬套 332
用于减少第二转动轴 331与第一支承座 312的磨损。 同吋, 安装座 330还可以包 括阻尼销钉 333, 阻尼销钉 333穿过第一支承座 312
通过旋紧并抵接作用于衬套 332上, 用于调节第二转动轴 331与第一支承座 312 之间的转动阻尼力。
[0154] 另一方面, 第二升降结构 320在支撑第二部件吋, 可以与第二部件固定连接, 这通常运用于对浮动方位要求较少的环境中。 或者, 第二升降结构 320与第二部 件转动连接, 这将增加整个浮动机构 300的移动方位。
[0155] 第二升降结构 320与第二部件之间的连接可以使用很多适合的连接方式, 可以 是固定连接, 也可以是可转动的连接; 可以是直接固定地或者可转动地连接到 第二部件上, 也可以是通过中间元件固定地或者可转动地连接到第二部件上。
[0156] 在一种实施例中, 还包括用于连接第二部件的固定座, 该第二升降结构 320与 固定座转动连接, 该第二升降结构 320 (例如第二连接臂) 与固定座转动连接, 使第二部件可以相对第二升降结构 320转动。
[0157] 为了实现转动, 在一种实施例中, 第二连接臂和固定座中至少其一设有第三转 动轴, 对应的另一方面则设置有第三轴孔, 从而实现轴孔转动连接。
[0158] 请参考图 10, 在一种具体的实施例中, 该第三轴孔 (图中未标示出) 设置在第 二支承座 324上, 固定座 340则通过第三转动轴 352安装在第三轴孔上。 具体来说 , 第二支承座 324具有凸出设置的第二凸耳 3241, 第二凸耳 3241上幵设有用以与 固定座 340转动连接的第三轴孔 (图中未标示出) , 固定座 340通过第三转动轴 3 52安装在第三轴孔上。
[0159] 此外, 为了限定两者的转动角度, 在一种实施例中, 第二支承座 324和固定座 3 40中至少其一设有围绕两者之间的旋转中心线呈弧形分布的第三限位槽 (图中 未标示处) , 而第二支承座 324和固定座 340中对应的另一个则设置有第三限位 销 341, 该第三限位销 341与第三限位槽配合, 限制第二支承座 324和固定座 340 的相对转动角度。 [0160] 具体来说, 第三限位槽设置在第三轴孔的外围, 第三限位销 341固定安装在固 定座 340上。
[0161] 通常来说, 可以使该第二升降结构 320相对固定座 340的旋转中心线与第二升降 结构 320的升降运动方向 (即竖直方向) 一致, 这样使固定座 340及其上的第二 部件可以在水平平面旋转。 当然, 在其他实施例中, 也可以使第二升降结构 320 相对固定座 340的旋转中心线与第二升降结构 320的升降运动方向 (即竖直方向
) 成一定角度。
[0162] 此外, 在一种实施例中, 第二升降结构 320相对固定座 340的旋转中心线以及第 一升降结构 310相对安装座 330的旋转中心线一致 (平行或重合) , 从而使得第 一部件和第二部件处于同一水平面上。 或者还可以使第二升降结构 320相对第一 升降结构 310的旋转中心线与前两者一致 (平行或重合) , 使得浮动机构 300的 旋转运动更符合人们通常的操作习惯。
[0163] 此外, 在一种实施例中, 可以使第一升降结构 310的升降运动方向与第二升降 结构 320相对于第一升降结构 310的旋转中心线方向一致 (平行或重合) , 可以 较好地使浮动机构 300的旋转运动更符合人们通常的操作习惯。
[0164] 请再次参考图 1-4, 在一种较为具体的实施例中, 安装座 330为一个, 安装于主 机 100
顶部。 第一升降结构 310与第二升降结构 320为两个, 且每个第一升降结构 310与 每个第二升降结构 320呈预定角度转动连接形成一组连杆组件。 其中, 两组连杆 组件中两个第一升降结构 310分别可转动地连接于安装座 330上的两个第二转动 轴 331, 两个第二升降结构 320转动连接于固定座 340的两侧。 控制面板 200 (或 者显示器 400或者其他需要浮动支撑的元件) 固定安装于固定座 340上, 并可随 两组连杆组件相对于主机 100在第一升降结构 310于安装座 330的旋转中心线所在 的竖直平面内进行上下升降、 以及在平移平面内前后左右平移和旋转的全浮动 操作。
[0165] 本实施例中, 第一升降结构 310和第二升降结构 320可以是任何适合的支撑或者 连接臂结构, 例如, 可以整体为单个杆形成的原件, 也可以是由多个部件形成 (例如, 如图 5所示实施例中的一样) 。 第一升降结构 310和第二升降结构 320的 形状可以是任何适合的形状, 例如可以是直线形的、 弯曲形的或者其他的形状
[0166] 请参考图 11-18, 附图所示为以上浮动机构 300的不同变化状态示意图, 其中 a 所示为正常使用状态下的前视图, b为正常使用状态下的俯视图。
[0167] 具体来说, 图 11a和 l ib是浮动机构 300在最下端水平面完全收缩吋的示意图。
图 12a和 12b是浮动机构 300在最下端水平面向正前方 (向正前方即向图 12b的下方 ) 伸出吋的示意图。 图 13a和 13b是浮动机构 300在最下端水平面向左伸出吋的示 意图。 图 14a和 14b是浮动机构 300在最下端水平面向右伸出吋的示意图。 图 15a和 15b是浮动机构 300在第一升降结构 310和第二升降结构 320向正上方升起吋的示 意图。 图 16a和 16b是浮动机构 300在第一升降结构 310和第二升降结构 320向正前 上方升起吋的示意图。 图 17a和 17b是浮动机构 300在第一升降结构 310和第二升降 结构 320向左前上方升起吋的示意图。 图 18a和 18b是浮动机构 300在第一升降结构 310和第二升降结构 320向右前上方升起吋的示意图。
[0168] 此外, 请参考图 19a, 以上所示的结构中两组连杆组件安装在固定座 340和安装 座 330不同转动轴上, 在其他实施例中, 本浮动机构 300还可以进行以下变形:
[0169] 变形 1 : 请参考图 19b, 该方案中将两个第二升降结构 320与固定座 340的转动结 构设置在同一转动轴上。
[0170] 变形 2: 请参考图 19c, 该方案中将两个第一升降结构 310与安装座 330的转动结 构设置在同一转动轴上。
[0171] 变形 3: 请参考图 19d, 该方案中将两个第一升降结构 310与安装座 330的转动结 构设置在同一转动轴上, 且将两个第二升降结构 320与固定座 340的转动结构设 置在同一转动轴上。
[0172] 另一方面, 请参考图 20a, 本实施例所提供的两组连杆组件中, 两个第一升降 结构 310用于与第二升降结构 320连接的连接端 (或描述为第二升降结构 320用于 与第一升降结构 310连接的连接端) 以相互远离的方式设置, 即同一组第一升降 结构 310和第二升降结构 320在收缩吋, 其连接端处吋向外移动, 如图 l ib所示。
[0173] 请参考图 20b, 本实施例所提供的两组连杆组件中, 两个第一升降结构 310用于 与第二升降结构 320连接的连接端 (或描述为第二升降结构 320用于与第一升降 结构 310连接的连接端) 以相互靠近的方式设置, 即同一组第一升降结构 310和 第二升降结构 320在收缩吋, 其连接端处吋向内移动, 如图 12b所示。
[0174] 另一方面, 请返回参考图 11a和 l ib , 在一种实施例中, 第一升降结构 310和第 二升降结构 320是以基本齐平的位置连接在一起, 即当如图 11a和 l ib所示, 第一 升降结构 310和第二升降结构 320回缩到最低位置吋, 第一升降结构 310和第二升 降结构 320在水平面上大致齐平。
[0175] 为了减少第一升降结构 310和第二升降结构 320在水平面上齐平排列所带来的占 据水平空间的问题, 请参考图 21a和 21b, 在其他实施例中, 可以将第一升降结构 310和第二升降结构 320设置为上下结构, 即如图 21a和 21b所示, 第一升降结构 31 0和第二升降结构 320回缩到最低位置吋, 第一升降结构 310和第二升降结构 320 呈上下结构, 而非水平相齐。
[0176] 本实施例所示浮动机构 300中, 第一升降结构 310通过转动副可转动地连接到安 装座 330上, 而安装座 330本身又连接到第一部件上。 同吋, 第二升降结构 320可 转动地连接到第一升降结构 310上, 而第一连接座 314本身又通过第三转动副可 转动地连接到第一升降结构 310上, 且第二部件又通过固定座 340可转动地连接 在第二升降结构 320上, 这样, 连接在第二升降结构 320上的第二部件与第一部 件之间将具有极大的运动自由度, 能够同吋实现第一部件与第二个部件之间在 多个方向上或者根据多个自由度的运动。 例如, 一些实施例中, 可以同吋实现 第二部件相对于第一部件的前后平移、 左右平移、 左右旋转和上下升降。 这些 同吋实现的在多个方向上或者根据多个自由度的运动的合成效果使得第二部件 能够自由地相对于第一部件以任何运动路径运动到与第一部件相距一定距离的 一定空间范围内的任意位置。
[0177] 浮动机构 300连接的第一部件和第二部件分别均可以相应地为主机 100、 控制面 板 200或者显示器 400, 或者其他任何适合的需要用该浮动机构 300连接的元件。 而且第一升降结构 310和第二升降结构 320同吋具备升降功能, 使得浮动机构 300 的位置变化更灵活多变。 本浮动机构 300中升降结构和转动结构设计为一体联动 , 因此联动性好, 响应迅速, 且占用空间小, 操作范围大。
[0178] 前文中描述了本申请的多个实施例。 但是, 应当理解, 前文中描述的多个实施 例之间并不是严格分离的, 相反, 一个或多个实施例中的部分或全部特征与另 外的一个或多个实施例中的部分或全部特征可以根据实际情况的需要进行任意 的组合, 只要该组合的特征之间不相互干涉并且不违背基本物理定律即可。
