 本发明的最佳实施方式
为使本领域技术人员更好地理解本实用新型的技术方案，下面结合附图和具体实施方式对本实用新型作进一步详细描述。
在实用新型的一些描述中，除非另有明确的规定和限定，术语“安装”、“连接”、“相连”或者“固定”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是通过中间媒体间接连接，可以是两个元件内部的连通或者两个元件的互相作用关系。以及，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、等指示的方位或位置关系为基于附图所示的方位或位置关系，仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
如图1至图6所示，本实用新型提供一种直驱系统100，包括：包括基座110以及与基座间隔设置的至少一个滑座120；其中，基座110上设置有导轨130与定子组件140，滑座120上固定有与定子组件140相对设置的动子组件150，动子组件150与定子组件140相互作用以驱动滑座120在导轨130上滑动；其中，导轨130在基座110上沿滑座120的滑动方向的正投影至少部分落在基座110外侧。
本实施例的基座及其上设置的导轨、定子组件相当于定子模块，滑座及动子组件相当于动子模块，多个定子模块相拼接以实现直驱系统长度可调节。另外，将导轨在基座上沿滑座的滑动方向的正投影至少部分落在基座外侧，以使得动子和定子模块拼接时，最先接触的是导轨，可以保证导轨的衔接流畅性，其它部分间距略大，不会出现导轨未完全接触，其它部分先接触上的情况。
需要说明的是，本实施例的定子组件包含直线、圆弧、扇形等多种形状，共同组成一个定子系统，对此不做具体限定。
进一步需要说明的是，在每个定子模块上可设置一个动子模块，当然，一个定子模块上也可配套有两个、三个或多个动子模块。
具体的，如图1至图4所示，基座110包括底板111，导轨130包括设置在底板111内表面的安装部131，以及自安装部131沿滑座120的滑动方向延伸的至底板111外的拼接部132。也就是说，该拼接部伸出基座一定尺寸，以确保模块之间最先接触的是导轨结构。
在一些优选实施例中，直驱系统可以包括多个滑座，多个滑座通过拼接部滑动安装在所述导轨上，也就是说，每个模块通过拼接部拼接在一起，滑座通过各拼接部滑动至拼接在一起的各定子模块的导轨上，与各基座发生相对滑动。
进一步的，如图1至图6所示，基座110还包括与底板111相对间隔设置的顶板112，定子组件140包括设置在顶板112靠近底板111一侧的第一导磁体141，以及固定于第一导磁体141上且间隔设置的多个线圈142；动子组件150包括设置在滑座120朝向顶板112一侧的第二导磁体151，以及固定于第二导磁体151上且间隔设置的多个磁钢152，磁钢152与线圈142相对设置。
应当理解的是，线圈还与外部电源连接，并通过与线圈连接的外部驱控系统控制线圈通电，当线圈通入电流时，线圈产生行波磁场，磁钢感应出磁场，磁钢、线圈之间产生气隙磁场，磁钢和线圈之间产生推力以驱动滑座沿着导轨进行运动。
在一些优选实施例中，如图5所示，第一导磁体141包括导磁基板141a以及设置于导磁基板141a上的多个齿部141b，线圈142套设于齿部141b上。
需要说明的是，本实施例的磁钢可以先安装在第二导磁体上，再将整体安装在滑座上。
在另一些优选实施例中，如图1至图4、图6所示，滑座120朝向底板111的一侧设置有可滑动的至少一个滑块121，滑座120通过滑块121在导轨130上滑动。
需要说明的是，本实施例对于滑块的结构及数量不做具体限定，可以根据导轨的结构进行具体设置，例如，当导轨两侧设置有滑动部时，可以在滑座的下方对称设置两个或四个滑块，使滑块在滑动部上滑动。此时滑块沿滑座的运动方向对称设置于导轨的相对两侧，使得滑座的运动更加的平稳。
进一步的，如图1至图4所示，基座110还包括连接于顶板112与底板111之间的侧板113，侧板113沿滑座120滑动方向设置有至少一个第一位置反馈件160，滑座120朝向侧板113的一侧设置有第二位置反馈件170，第二位置反馈件170与至少一个第一位置反馈件160相对间隔设置。
在一些优选实施例中，如图1至图4所示，第一位置反馈件160的数量为多个，多个第一位置反馈件160等间隔布置在侧板113上。
作为进一步的优选方案，侧板上间隔设置有多个安装槽，第一位置反馈件设置在对应的安装槽内。
作为更进一步的优选方案，第一位置反馈件可采用栅尺，第二位置反馈件可采用栅尺读头。
本实施例的第二位置反馈件同步在滑座上运动，当滑座经过第一位置反馈件时，第一位置反馈件会感应到第二位置反馈装置上的位置信息，将动子模块的位置信息传递给外部的驱控系统，以实现对动子组件进行驱动控制。
需要说明的是，本实施例对滑座的具体结构不做具体限定，可以由多个子结构组合而成，也可以是一个整体结构。
具体地，如图1至图4、图6所示，滑座120包括与顶板112相对间隔设置的第一板体122，第二导磁体151与多个磁钢152设置在第一板体122朝向顶板112的一侧，滑块121设置在第一板体122朝向底板111的一侧，第二位置反馈件170设置在第一板体122朝向侧板113的一侧。
进一步地，请继续参考图1至图4、图6，滑座120还包括自第一板体122向上延伸至顶板112上方的延伸板123，以及连接延伸板123且与第一板体122相对设置的第二板体124，即第二板体124设置在顶板112上方，定子组件与动子组件产生相对推力时，以驱动滑座与基座发生相对滑动。
本实用新型提供一种直驱系统，与现有技术相比具有以下有益效果：通过设置导轨在基座上沿滑座的滑动方向的正投影至少部分落在基座外侧，可以确保动子模块和定子模块拼接时，最先接触到的是导轨结构，以确保直驱系统系统的滑动流畅，降低系统的装配难度与维修难度。
可以理解的是，以上实施方式仅仅是为了说明本实用新型的原理而采用的示例性实施方式，然而本实用新型并不局限于此。对于本领域内的普通技术人员而言，在不脱离本实用新型的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本实用新型的保护范围。
