诸如“在…下面”、“在…之下”、“较下”、“在…下方”、“在…之上”、“较上”等等之类的空间相对术语在本文中可以为了便于描述而用来描述如图中所图示的一个元件或特征与另一个(些)元件或特征的关系。将理解的是，这些空间相对术语意图涵盖除了图中描绘的取向之外在使用或操作中的器件的不同取向。例如，如果翻转图中的器件，那么被描述为“在其他元件或特征之下”或“在其他元件或特征下面”或“在其他元件或特征下方”的元件将取向为“在其他元件或特征之上”。因此，示例术语“在…之下”和“在…下方”可以涵盖在…之上和在…之下的取向两者。诸如“在…之前”或“在…前”和“在…之后”或“接着是”之类的术语可以类似地例如用来指示光穿过元件所依的次序。器件可以取向为其他方式(旋转90度或以其他取向)并且相应地解释本文中使用的空间相对描述符。
本文中使用的术语仅出于描述特定实施例的目的并且不意图限制本公开。如本文中 使用的，单数形式“一个”、“一”和“该”意图也包括复数形式，除非上下文清楚地另有指示。将进一步理解的是，术语“包括”和/或“包含”当在本说明书中使用时指定所述及特征、整体、步骤、操作、元件和/或部件的存在，但不排除一个或多个其他特征、整体、步骤、操作、元件、部件和/或其群组的存在或添加一个或多个其他特征、整体、步骤、操作、元件、部件和/或其群组。如本文中使用的，术语“和/或”包括相关联的列出项目中的一个或多个的任意和全部组合，并且短语“A和B中的至少一个”是指仅A、仅B、或A和B两者。
将理解的是，当元件或层被称为“在另一个元件或层上”、“连接到另一个元件或层”、“耦合到另一个元件或层”或“邻近另一个元件或层”时，其可以直接在另一个元件或层上、直接连接到另一个元件或层、直接耦合到另一个元件或层或者直接邻近另一个元件或层，或者可以存在中间元件或层。相反，当元件被称为“直接在另一个元件或层上”、“直接连接到另一个元件或层”、“直接耦合到另一个元件或层”、“直接邻近另一个元件或层”时，没有中间元件或层存在。然而，在任何情况下“在…上”或“直接在…上”都不应当被解释为要求一个层完全覆盖下面的层。

相关技术中的三维打印方法，如熔融沉积成型(Fused Deposition Modeling，FDM)，其是一种基于数字模型，利用粉末状金属或塑料等材料，通过逐层打印的方式构造三维物体的方法，其中使用到的三维打印机是以细丝的形式向打印头供给成型材料，成型材料在打印头内以电加热的方式被加热至熔融状态。打印头按照三维打印机的控制器产生的打印头相对基底移动的路径以一层一层的方式打印出三维物体。
在一些相关技术中，3D打印机的挤出部分由外壳进行保护，但是当挤出部分出现异常需要维修时，往往需要使用工具先拆除外壳才能进行内部结构维修，从而导致维修时间和维修难度的增加。
下面将参照图1至图4对本公开实施例的壳体组件1进行详细描述。图1示出了根据本公开的一些示例性实施例的用于3D打印机的挤出机构的壳体组件1的结构示意图； 图2示出了图1所示的壳体组件1的拆分结构示意图，其中盖体200从壳体100上拆卸；图3示出了根据本公开的一些示例性实施例的壳体100的结构示意图。
如图1至图3所示，壳体组件1包括：壳体100和盖体200。壳体100内部形成用于容纳挤出机构的空间，壳体100的一侧设置有开口。在一些实施例中，壳体100为近似长方体的结构，上述开口为长方形开口。当然，在另外一些实施例中，开口还可以是圆形、多边形等其它形状的开口。壳体100包括邻接设置在开口周缘的多个第一磁性元件110。盖体200可拆卸地设置在壳体100具有开口的一侧，用于开闭壳体100，盖体200在关闭时朝向壳体100的一侧设置有多个第二磁性元件210。
在本公开实施例中，壳体组件1用于3D打印机的挤出机构，是指挤出机构位于壳体组件1的内部，壳体组件1与挤出机构配合组装形成3D打印机的部分构造。
如图2所示，多个第一磁性元件110在壳体100上的设置位置分别与多个第二磁性元件210在盖体200上的设置位置相对应，以在盖体200关闭壳体100时，多个第一磁性元件110分别与多个第二磁性元件210吸附。
在一些实施例中，第一磁性元件110和第二磁性元件210可以为圆柱形磁铁，并且，第一磁性元件110和第二磁性元件210的圆柱形轴线可以和壳体100的宽度方向(即，图1所示的Y方向)平行，从而使得在盖体200封闭壳体100时，第一磁性元件110的圆柱形端面和对应的第二磁性元件210的圆柱形端面接触。虽然在图2的示例中，第一磁性元件110和第二磁性元件210的形状为圆柱形，但是可以理解，在另外一些实施例中，第一磁性元件110和第二磁性元件210还可以为立方体、长方体或球形等其他形状。第一磁性元件110和第二磁性元件210的数量可以相同，例如在图1至图3所示的实施例中，第一磁性元件110和第二磁性元件210的数量均为4个。4个第一磁性元件110分别设置在矩形开口的拐角内侧。4个第二磁性元件210分别设置在盖体200的对应位置上，即盖体200的四个拐角的位置。在将盖体200安装到壳体100上时，4个第一磁性元件110分别和4个第二磁性元件210对齐，以实现盖体200对壳体100的开口的完全封闭。
本公开实施例的壳体组件可以用于容纳3D打印机的挤出机构，在挤出机构正常工作期间，盖体200通过第一磁性元件110和第二磁性元件210保持在闭合位置，盖体200组件用于保护挤出机构。在挤出机构出现故障需要检修时，将盖体200拆卸下来，以便于对挤出机构进行检修。因此，该壳体组件的盖体200拆卸相对简单，无需使用其他工 具对盖体200进行拆卸，从而简化了维修过程。
壳体100还包括邻接设置在开口周缘的多个第一安装部120，多个第一安装部120中的每个第一安装部120均形成有槽口朝向盖体200的第一安装槽121，多个第一磁性元件110分别安装到多个第一安装部120的第一安装槽121中。如图3所示，壳体100的开口为矩形开口，上述第一安装部120的数量为4个，分别设置在矩形开口的四个拐角的内侧，上述第一安装部120可以和壳体100一体成型。第一安装部120设置在开口的4个拐角内侧，可以使得盖体200在壳体100上的固定更加牢固，防止盖体200脱落。第一安装部120可以近似为圆柱体结构，以便于和第一磁性元件110的形状相适配。第一安装槽121也可以为圆柱形，以与第一磁性元件110的形状相匹配，该圆柱形的第一安装槽121的轴线可以和壳体100的宽度方向(即，图1所示的Y方向)平行，以使得第一磁性元件110的朝向同样和壳体100的宽度方向平行。第一磁性元件110可以通过卡接或粘合的方式固定安装到第一安装槽121内。
盖体200在关闭时朝向壳体100的一侧还包括多个第二安装部220，多个第二安装部220中的每个第二安装部220均形成有槽口朝向壳体100的第二安装槽221，多个第二磁性元件210分别安装到多个第二安装部220的第二安装槽221中。第二安装槽221也可以为圆柱形，以和第二磁性元件210的形状相匹配，该圆柱形的第二安装槽221的轴线可以和壳体100的宽度方向(即，图1所示的Y方向)平行，以使得第二磁性元件210的朝向同样和壳体100的宽度方向平行。第二磁性元件120可以通过卡接或粘合的方式固定安装到第二安装槽221内。
图4示出了图1所示的壳体组件的壳体100与盖体200的结合部分的截面放大图，其中，该截面是图1中所示的壳体组件在Y-Z平面上的截面。如图4所示，多个第一安装部120中的每个第一安装部120均形成朝向盖体200敞开的凹部122，并且，多个第二安装部220中的每个第二安装部220均形成朝向壳体100突出的凸起222，以使得在盖体200关闭时，凸起222伸入到对应的凹部122内。在关闭盖体200的过程中，在第一磁性元件110和第二磁性元件210相互接触之前，上述凸起222先伸入对应的凹部122中，从而实现了壳体100和盖体200的预定位，防止壳体100和盖体200错位对接。另外，在盖体200关闭壳体100时，上述凹部122和对应凸起222的结合可以防止盖体200和壳体100的相对滑动，特别是在图1所示的X-Z平面上的相对滑动。
在一些实施例中，第一安装槽121形成在对应的第一安装部120的凹部122中，并 且，第二安装槽221形成在对应的第二安装部220的凸起222中。如图4所示，上述凹部122也可以是圆柱形形状，并且同一个第一安装部120的凹部122和第一安装槽121的轴线相同，以使得第一安装部120本身、凹部122和第一安装槽121同轴设置，其中，第一安装槽121的直径小于对应凹部122的直径，也就是说，第一安装槽121形成在对应凹部122的底面上。如图4所示，第一磁性元件110朝向盖体200一侧的表面可以和第一安装槽121的上边缘(即对应凹部122的底面)平齐。上述凸起222也可以是圆柱形形状，并且同一个第二安装部220的凸起222和第二安装槽221的轴线相同，以使得第二安装部220本身、凸起222和第二安装槽221同轴设置，其中，第二安装槽221的直径小于对应凸起222的直径，也就是说，第二安装槽221形成在对应凸起222的顶面上。如图4所示，第二磁性元件210朝向壳体100一侧的表面可以和第二安装槽221的上边缘(即对应凸起222的顶面)平齐。如此设置，在盖体200封闭壳体100时，可以实现第一磁性元件110和对应的第二磁性元件210之间的相对表面的充分接触。另外，凸起222的直径可以等于或略小于对应凹部122的直径，以便于凸起222伸入到对应的凹部122中。
在本公开的一些实施例中，壳体组件还包括磁场传感器300。磁场传感器300设置在壳体100或盖体200上，配置成通过检测磁场强度来感测盖体200的开闭状态。如图3和图4所示，磁场传感器300可以设置在壳体100上，并且位于多个第一磁性元件110中的任一个第一磁性元件110的背离盖体200的一侧。磁场传感器300可以安装在壳体100内部，并且邻近多个第一安装部120中的其中一个第一安装部120设置，其可以感测来自于第一磁性元件110和第二磁性元件210的磁场大小。
上述磁场传感器300的工作原理是，当盖体200处于拆卸状态时(即壳体100处于打开状态)，磁场传感器300附近仅存在第一磁性元件110，因此其感测到的磁场强度较弱，从而判断壳体100处于打开状态。当盖体200处于安装状态时(即壳体100处于封闭状态)，磁场传感器300附近存在第一磁性元件110和第二磁性元件210两者，因此其感测到的磁场强度较强，从而判断壳体100处于封闭状态。具体地，可以预先设置一个磁场强度阈值，当磁场传感器300检测到高于该阈值的磁场强度时，确定壳体100处于封闭状态；当磁场传感器300检测到低于该阈值的磁场强度时，确定壳体100处于打开状态。上述磁场强度阈值可以根据第一磁性元件110和第二磁性元件210产生的磁场强度进行设置。在本公开的一些实施例中，上述磁场传感器300可以是霍尔传感器。另外， 上述磁场传感器300还可以和额外设置的提示器装置(例如：报警器或提示器等)电连接，用于将检测信号发送到该提示器装置中，以便于该提示器装置基于该检测信号提示壳体100的打开或封闭状态。
在一些实施例中，盖体200还包括把手部240。如图2所示，把手部240设置于盖体200的底部，以供用户抓握来开启壳体100。另外，如图3所示，壳体100上设置有多个气孔130，并且如图2所示，盖体200上同样设置多个气孔230，这些气孔有利于壳体100内部的挤出机构的散热。
根据本公开的另一个方面，还提供了一种3D打印机，包括：挤出机构和上述壳体组件1。挤出机构用于挤出打印材料，壳体组件1用于容纳挤出机构。在挤出机构正常工作期间，盖体200保持在封闭状态，壳体组件1用于保护挤出机构。在挤出机构出现故障需要检修时，将盖体200拆卸，以便于对挤出机构进行检修。
虽然在附图和前面的描述中已经详细地说明和描述了本公开，但是这样的说明和描述应当被认为是说明性的和示意性的，而非限制性的；本公开不限于所公开的实施例。通过研究附图、公开内容和所附的权利要求书，本领域技术人员在实践所要求保护的主题时，能够理解和实现对于所公开的实施例的变型。在权利要求书中，词语“包括”不排除未列出的其他元件或步骤，不定冠词“一”或“一个”不排除多个，并且术语“多个”是指两个或两个以上。在相互不同的从属权利要求中记载了某些措施的仅有事实并不表明这些措施的组合不能用来获益。
