在本文中，“第一”、“第二”等并非表示其重要程度或顺序等，仅用于表示彼此的区别，以利文件的描述。
为使图面简洁，各图中只示意性地表示出了与本实用新型相关的部分，它们并不代表其作为产品的实际结构。
图1为医用床水平驱动机构的一种示意性实施方式的结构示意图。如图1所示，该医用床包括一个床架91、一个床板92和一个医用床水平驱动机构(图中实线所示的部分)。床板92沿方向A及其反方向可运动地设置于床架91。
如图1所示，医用床水平驱动机构包括一个支架10、一个滚筒20、一个张紧轮81、一个传动带82、一个水平移动部件83和两个固定组件84；此外，医用床水平驱动机构在滚筒20的筒腔内还设置有一个电动机30和一个位置传感器41。水平移动部件83也被称 为拖车。
如图1所示，支架10用于固定连接医用床的床架91。滚筒20可转动地连接支架10。滚筒20能够通过转动来驱动医用床的床板92相对于床架91运动。
具体地，在本示意性实施方式中，滚筒20通过如下结构来驱动床板92运动。张紧轮81可转动地设置于床架91，且转动轴线与滚筒20的转动轴线平行。传动带82绕设于张紧轮81和滚筒20。传动带82例如为同步带，平皮带，楔形带等，张紧轮81和滚筒20具有与之匹配的传动结构。水平移动部件83用于固定连接床板92。图2为图1所示的医用床水平驱动机构的局部结构示意图，如图2所示，各固定组件84包括一个第一齿板841和一个第二齿板842。第一齿板841固定连接水平移动部件83。第二齿板842通过螺栓可拆卸地连接第一齿板841并能够与第一齿板841啮合，以阻止第一齿板841和第二齿板842在床板92的运动方向上相对移动。啮合的第一齿板841和第二齿板842能够通过啮合的齿夹持固定传动带82的一端。两个固定组件84分别夹持固定传动带82的两端。借此，滚筒20能够通过转动驱动传动带82运动，以带动床板92沿方向A及其反方向运动。但不限于此，在其他示意性实施方式中，滚筒20还可通过其他方式驱动床板92运动，例如通过设置于滚筒20的齿轮结构和设置于床板92的齿条结构实现直接驱动。
在本示意性实施方式中，张紧轮81相对于床架91的位置可沿床板92的运动方向调节，以张紧传动带82，该调节例如通过螺栓，具体地，张紧轮81的轮轴通过螺栓固定于床架91，通过转动螺栓可调节张紧轮81与床架91的相对位置。但不限于此，在其他示意性实施方式中，张紧轮81相对于床架91的位置可设置为固定不变。
在本示意性实施方式中，传动带82能够通过水平移动部件83和固定组件84固定于床板92，但不限于此，在其他示意性实施方式中，传动带82也可设置为直接连接床板92。
在本示意性实施方式中，水平移动部件83能够沿方向A及其反方向可运动地连接床架91，连接方式例如为滑动连接或通过滚轮连接。水平移动部件83用于固定床板92，以带动床板92相对于床架91运动。但不限于此，在其他示意性实施方式中，也可以是床板92直接可运动地连接床架91。
图3为图1所示的医用床水平驱动机构的局部剖视图。如图3所示，支架10包括一对支撑组件11。各支撑组件11包括一个连接件12和一个支撑轴13。连接件12用于固定连接床架91。支撑轴13固定连接连接件12，且其轴线与滚筒20的转动轴线重叠。两个支撑轴13一一对应地连接滚筒20轴向上的两端，以支撑滚筒20转动。该支架10的结构简单，便于加工且稳定性较好，但不限于此。
电动机30设置于滚筒20的筒腔内。电动机30的壳体固定连接其中一个支撑轴13。电动机30的输出轴31通过一个筒体连接座63连接滚筒20，以驱动滚筒20相对于支架10转动。位置传感器41设置于滚筒20的筒腔内。位置传感器41能够检测滚筒20的转动位置并生成一个位置信号，位置信号用于控制电动机30，以提高医用床水平驱动机构的驱动精度。位置传感器41例如为编码器。
本示意性实施方式的医用床水平驱动机构，其中支架10、滚筒20、电动机30和位置传感器41为集成式结构，通过支架10与床架91的组装和拆离即可实现该集成式结构的安装与拆卸，借此便于安装和维护，此外通过集成式的结构利于节省空间。
在示意性实施方式中，支撑轴13为空心轴结构，其空心通孔用于电动机30和位置传感器41的引出线穿过，借此使结构更加紧凑。
在示意性实施方式中，滚筒20呈圆管型。医用床水平驱动机构还包括两个端盖22，其固定连接滚筒20的轴向上的两端，以封闭滚筒20两端的开口。一对支撑组件11所包括的支撑轴13分别穿设于两个端盖22，以支撑滚筒20转动。借此利于滚筒20内部结构的防水防尘。
图4为医用床水平驱动机构的另一种示意性实施方式的局部剖视图。本示意性实施方式的医用床水平驱动机构与图1所示的医用床水平驱动机构相同或相似之处在此不再赘述，与之不同之处如下所述。

减速机50和制动器70设置于支撑套筒61的筒腔内。减速机50例如为行星减速机或谐波减速机。电动机30的输出轴的穿出两个连接法兰62的两端分别连接减速机50的输入轴和制动器70。减速机50的输出轴52可转动地穿设于支撑套筒61未连接支撑轴13的一端，借此可提高使用过程中减速机50的输出轴52的稳定性。减速机50的输出轴52的穿出支撑套筒61的一端通过筒体连接座63固定连接滚筒20。电动机30通过减速机50连 接滚筒20，以驱动滚筒20转动，借此可增加转矩。
速度传感器42设置于支撑套筒61的筒腔内。速度传感器42能够检测电动机30的输出轴的转速并生成一个转速信号，转速信号用于控制电动机30，以提高医用床水平驱动机构的驱动精度。速度传感器42例如由编码器或旋转变压器与霍尔传感器组成。
