 本发明的实施方式
下面结合附图和实施方式对本实用新型作进一步说明。
为使本实用新型的上述目的、特征和优点能够更加明显易懂，下面结合附图对本实用新型的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本实用新型。但是本实用新型能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本实用新型内涵的情况下做类似改进，因此本实用新型不受下面公开的具体实施例的限制。
如图1至图3所示，在一个实施例中，直线驱动电机包括：滑动本体100、磁生机构200与磁性组件300，磁生机构200与磁性组件300磁性配合并用于驱动滑动本体100自身进行动作，磁性组件300包括第一磁性件310、第二磁性件320与多个第三磁性件330，第一磁性件310、第二磁性件320与多个第三磁性件330均沿滑动本体100的动作方向在滑动本体100上间隔设置，第一磁性件310、第二磁性件320与多个第三磁性件330均与磁生机构200磁性配合，第一磁性件310靠近滑动本体100的沿所述动作方向Y其中一端，第二磁性件320靠近滑动本体100沿所述动作方向Y的另一端，多个第三磁性件330位于第一磁性件310与第二磁性件320之间，第一磁性件310的安装厚度与第二磁性件320的安装厚度均低于第三磁性件330的安装厚度；安装厚度指的是第一磁性件310，第二磁性件320或第三磁性件330在沿垂直于滑动本体100的动作方向Y的Z方向上的厚度。或第一磁性件310的端部表面宽度与第二磁性件320的端部表面宽度均小于第三磁性件330的端部表面宽度。端部表面宽度指的是第一磁性件310，第二磁性件320或第三磁性件330在沿平行于滑动本体100的动作方向Y的方向上的宽度或在垂直于滑动本体100的动作方向Y的X方向上的宽度。
上述直线驱动电机在使用时，通过磁生机构200与磁性组件300磁性配合，从而实现滑动本体100自身进行动作。即磁生机构200在通电情况下会产生磁场，此时磁性组件300会对磁场的磁感线进行切割，从而产生了用于驱动滑动本体100自身进行动作的推力。在实现磁生机构200与磁性组件300磁性配合时，可以将磁生机构200装设在滑动本体100的动作部（指滑动本体100进行动作的部位）上，将磁性组件300装设在滑动本体100的基面（指滑动本体100上与动作部位相对应的固定部分）上。或者将磁生机构200装设在滑动本体100的基面上，将磁性组件300装设在滑动本体100的动作部上。进一步地，磁性组件300通过第一磁性件310、第二磁性件320与多个第三磁性件330实现与磁生机构200的磁性配合，且第一磁性件310、第二磁性件320与多个第三磁性件330均沿滑动本体100的滑动方向Y在滑动本体100上间隔设置，从而使得滑动本体100自身进行动作的整个过程中能够得到持续的推力。上述直线驱动电机通过将第一磁性件310的安装厚度与第二磁性件320的安装厚度均低于第三磁性件330的安装厚度，或第一磁性件310的端部表面宽度与第二磁性件320端部表面宽度均小于第三磁性件330的端部表面宽度，从而能够有效降低滑动本体100两端的推力波动。
在一个实施例中，磁生机构200指在通电情况下可以产生磁场。例如：铁芯与一个以上的绕组卷设配合。第一磁性件310、第二磁性件320与第三磁性件330可以为磁钢或磁铁。
在一个实施例中，第一磁性件310与第二磁性件320在滑动本体100内部的安装厚度相一致，即第一磁性件310与第三磁性件330具有第一厚度差，第二磁性件320与第三磁性件330也具有第一厚度差。此时第一厚度差的具体数值可以通过仿真方法（指运用各种模型和技术对实际问题进行建模，并通过试验已解决相应的实际问题）进行确定。
在一个实施例中，第一磁性件310的端部表面宽度指第一磁性件310朝向磁生机构200的端部的宽度。第二磁性件320的端部表面宽度指第二磁性件320朝向磁生机构200的端部的宽度。第三磁性件330的端部表面宽度指第三磁性件330朝向磁生机构200的端部的宽度。例如：第一磁性件310、第二磁性件320与第三磁性件330可以为矩形端部，则第一磁性件310与第二磁性件320在滑动本体100内部的端部表面宽度相一致，即第一磁性件310与第三磁性件330具有第一宽度差，第二磁性件320与第三磁性件330也具有第一宽度差。此时第一宽度差的具体数值可以通过仿真方法（指运用各种模型和技术对实际问题进行建模，并通过试验已解决相应的实际问题）进行确定。
如图2至图4所示，在一个实施例中，滑动本体100包括基座110与滑动座120，滑动座120与基座110滑动配合，滑动座120与基座110配合形成安装腔130，磁生机构200与磁性组件300装设在安装腔130中，磁生机构200装设在滑动座120上，磁性组件300装设在基座110上，或磁生机构200装设在基座110上，磁性组件300装设在滑动座120上。具体地，在选择滑动座120与基座110时，需要根据磁生机构200在通电情况下所能产生的磁场范围，以确定滑动座120与基座110之间的间隔距离，从而保证磁性组件300在装设到滑动座120或基座110上后，磁性组件300能够有效切割磁生机构200的磁场（另外，这仅仅是其中一种实施方式，还可以根据磁生机构200在通电情况下所能产生的磁场范围，确定磁性组件300在滑动座120或基座110上的安装厚度。）进一步地，在对磁生机构200与磁性组件300进行装设时，可以根据实际需要灵活选择磁生机构200与磁性组件300在滑动本体100上的安装位置，例如：磁生机构200装设在滑动座120上，磁性组件300装设在基座110上，或磁生机构200装设在基座110上，磁性组件300装设在滑动座120上。
如图1所示，在一个实施例中，基座110包括安装基板111、第一拼接板112与第二拼接板113，第一拼接板112与安装基板111的其中一侧安装配合，第二拼接板113与安装基板111的另一侧安装配合，第一拼接板112与第二拼接板113相对且间隔设置。第一拼接板112与第二拼接板113均与滑动座120滑动配合。具体地，通过安装基板111、第一拼接板112、第二拼接板113与滑动座120围成上述安装腔130，通过控制第一拼接板112与第二拼接板113的安装高度，确定滑动座120与安装基板111之间的间隔距离。进一步地，第一拼接板112与第二拼接板113可以与安装基板111卡接固定或螺纹固定。即当需要改变滑动座120与基座110之间的间隔距离时，只需更换不同安装高度的第一拼接板112与第二拼接板113，无需将基座110进行整体更换。
如图1所示，在一个实施例中，第一拼接板112上设有第一滑槽1121，第二拼接板113上设有第二滑槽1131，第一拼接板112通过第一滑槽1121与滑动座120滑动配合，第二拼接板113通过第二滑槽1131与滑动座120滑动配合。具体地，第一拼接板112上的第一滑槽1121可以根据滑动座120的侧部进行对应开设，一方面保证了第一拼接板112与滑动座120的滑动配合效果，另一方面也使得第一拼接板112与滑动座120的对应安装更加方便。第二拼接板113上的第二滑槽1131可以根据滑动座120的侧部进行对应开设，一方面保证了第二拼接板113与滑动座120的滑动配合效果，另一方面也使得第二拼接板113与滑动座120的对应安装更加方便。这仅仅是其中一种实施方式，例如：直线驱动电机还包括第一滑轨140与第二滑轨150，第一滑轨140至少部分收容于第一滑槽1121内并与第一拼接板112安装配合，滑动座120靠近第一拼接板112的一侧与第一滑轨140滑动配合，第二滑轨150至少部分收容于第二滑槽1131内并与第二拼接板113安装配合，滑动座120靠近第二拼接板113的一侧与第二滑轨150滑动配合。上述这种实施方式可以有效降低第一拼接板112与滑动座120之间的滑动摩擦力，及可以有效降低第二拼接板113与滑动座120之间的滑动摩擦力。
如图1所示，在一个实施例中，滑动座120靠近第一拼接板112的一侧设有第三滑槽121，滑动座120靠近第二拼接板113的一侧设有第四滑槽122，滑动座120通过第三滑槽121与第一滑轨140滑动配合，滑动座120通过第四滑槽122与第二滑轨150滑动配合。具体地，滑动座120靠近第一拼接板112的一侧通过第三滑槽121与第一滑轨140滑动配合，滑动座120靠近第二拼接板113的一侧侧通过第四滑槽122与第二滑轨150滑动配合。即使得第一滑轨140能够伸入到滑动座120内部与滑动座120滑动配合，以及第二滑轨150能够伸入到滑动座120内部与滑动座120滑动配合。上述这种实施方式能够避免滑动座120与基座110在滑动连接时留有缝隙，提高了滑动座120与基座110的贴合度，同时也能够有效避免杂质进入到滑轨上（避免直线驱动电机出现异响）。
如图3至图5所示，在一个实施例中，磁生机构200包括铁芯座210与绕组件，绕组件绕设在铁芯座210上，铁芯座210装设在滑动座120上或基座110上。具体地，铁芯座210上间隔设有两个以上的安装柱211，即绕组线圈220可以一一对应的绕设在安装柱211上。即可以通过控制在铁芯座210上加装绕组线圈220的个数来控制磁生机构200的磁感应强度。
如图1所示，在一个实施例中，磁性组件300还包括磁轨340，磁轨340由导磁材料制成，可以将磁感应线完全封闭在安装腔130内，避免磁泄露。磁轨340沿滑动本体100的动作方向Y装设在滑动本体100内部，第一磁性件310、第二磁性件320与第三磁性件330均间隔装设在磁轨340上，第一磁性件310位于磁轨340沿滑动本体的动作方向Y的其中一端，第二磁性件320位于磁轨340沿滑动本体的动作方向Y的另一端，当铁芯座210装设在滑动座120上时，磁轨340装设在基座110上，且铁芯座210装有绕组的一面朝向磁轨340装有第一磁性件310、第二磁性件320与第三磁性件330的一面；当铁芯座210装设在基座110上时，磁轨340装设在滑动座120上，且铁芯座210装有绕组的一面朝向磁轨340装有第一磁性件310、第二磁性件320与第三磁性件330的一面。
具体地，根据安装需要，为了避免磁生机构200与磁性组件300之间所产生的推力出现波动，多个第三磁性件330需要满足在滑动本体100内部的安装高度相一致，因此，通过磁轨340可以为第三磁性件330提供一个平整的安装面。另外，可以在磁轨340装入滑动本体100之前完成第一磁性件310、第二磁性件320与多个第三磁性件330在磁轨340上的安装。相较于直接将第一磁性件310、第二磁性件320与多个第三磁性件330直接装设在滑动座120或基座110上的安装方式，本实施例的这种实施方式安装更加方便，且能够有效降低磁性组件300在安装时所出现的误差。
如图1和图5所示，在一个实施例中，直线驱动电机还包括栅尺400与栅尺读头500，栅尺400装设在基座110上，栅尺读头500装设在滑动座120上，且栅尺读头500的感应端对应朝向栅尺400；或栅尺400装设在滑动座120上，栅尺读头500装设在基座110上，且栅尺读头500的感应端对应朝向栅尺400。具体地，滑动座120与基座110在进行相对移动时，栅尺读头500与栅尺400之间也会产生相对位移，此时栅尺读头500可以通过栅尺400上的测量值进行读取，从而获得滑动座120与基座110的位移变化情况，即可以根据栅尺读头500所反馈的信息结果判断直线驱动电机的工作情况。这仅仅是其中一种实施方式，例如：还可以利用霍尔传感器来检测滑动座120与基座110的相对位移。

此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本实用新型的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本实用新型中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本实用新型中的具体含义。
在本实用新型中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
