Description

电加热装置、供暖、通风和/或空调装置和机动车辆
本申请要求于2019年12月30日递交的第201922445724.8号中国专利申请的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本申请涉及一种用于机动车辆的供暖、通风和/或空调装置的电加热装置。本申请还涉及一种包括电加热装置的供暖、通风和/或空调装置。此外，本申请还涉及一种包括上述供暖、通风和/或空调装置的机动车辆。
背景技术
电加热装置配备在机动车辆的供暖、通风和/或空调装置中。在一些情况下，在车辆冷启动时，电加热装置在热交换器起作用之前暂时地承担加热乘客舱的功能。在一些情况下，例如在电动车中，电加热装置完全承担加热乘客舱的功能。
电加热装置通常设置在机动车辆的中央操作面板下方的空间内且大体平行于所述中央操作面板。电加热装置布置在鼓风机的下游，鼓风机送出的空气通过电加热装置且被加热，最后经由中央操作面板的格栅到达驾驶舱的乘客区域。
电加热装置还包括加热单元以及设置在加热单元一端的壳体，壳体中容纳有加热单元的控制模块。在传统的设计中，壳体在其垂直于厚度方向的较大表面处设置有接插件，以便通过线束允许外部电源向电加热装置的控制模块供电。然而，随着机动车辆的发展，中央操作面板下方的电加热装置的安装空间变得非常有限，特别是沿电加热装置的厚度方向。一旦在电加热装置垂直于厚度方向的较大表面处设置有接插件，电加热装置连同线束和插头将在厚度方向上占据较大的尺寸，使得电加热装置整体厚度较大，无法满足实际的安装要求。
申请内容
本申请旨在至少解决上述问题，并提出一种适配安装空间、连接可靠、安装便捷的电加热装置。
为此，本申请提出了一种用于机动车辆的供暖、通风和/或空调装置的电加热装置，所述电加热装置包括壳体和容纳在壳体中的控制模块，所述壳体呈块状且其沿第一方向的尺寸大于第二方向的尺寸，所述第一方向和第二方向相互垂直，所述控制模块包括汇流排，所述汇流排包括形成用于线束的接口的汇流排正端子和汇流排负端子，所述线束用于输入电流且包括线束正端子和线束负端子，所述线束沿所述第一方向延伸至所述接口，在所述接口处，所述线束正端子和线束负端子与相应的汇流排正端子和汇流排负端子电连接。
相对于现有设计而言，这样的设计使得电加热装置的壳体在第二方向上不具有额外的厚度，提供了电加热装置对于沿第二方向较为狭窄的安装环境的良好适应性。
在一些实施例中，所述汇流排正端子和汇流排负端子压接至相应的线束正端子和线束负端子。采用压接的方案，可以较低的成本为汇流排和线束的连接提供良好的抗拉拔性能，由此实现汇流排正端子、汇流排负端子和线束正端子和线束负端子的可靠连接。
在一些实施例中，所述汇流排正端子和汇流排负端子焊接至相应的线束正端子和线束负端子。
在一些实施例中，所述接口为位于壳体的垂直于第一方向的外表面处的接插件，所述汇流排正端子和汇流排负端子从所述壳体的外表面处露出。采用插接件的方案，可以简单快捷的方式实现汇流排和线束的可靠连接。
在一些实施例中，所述第一方向为重力方向。由于将线束的延伸方向布置在重力方向，水或灰尘由于重力的作用不容易进入到壳体内，从而起到防水防尘的效果。
在一些实施例中，所述壳体包括从壳体的内表面沿所述第二方向凸起的绝缘肋，所述绝缘肋沿所述第一方向延伸，所述汇流排正端子和汇流排负端子分别布置在所述绝缘肋的一侧。由此，可避免汇流排正端子和负端子之间的短路风险。
在一些实施例中，所述壳体在垂直于第一方向的壁处的包括出线孔，所述出线孔允许所述线束沿所述第一方向进入所述壳体内部并延伸至所述接口。
在一些实施例中，所述壳体包括第一壳体和第二壳体，所述第一壳体和第二壳体沿所述第二方向组装在一起且共同界定壳体的内部空间，所述出线孔包括第一半部和第二半部，所述第一半部形成在所述第一壳体中，所述第二半部形成在所述第二壳体中。以这样的方式，线束和汇流排的连接以及壳体的组装可以以简单的方式进行，即先完成线束和汇流排的连接，在将第一壳体和第二壳体组装在一起。
在一些实施例中，所述第一壳体和第二壳体通过卡扣结构组装在一起。由此，第一壳体和第二壳体的组装可以以简单快捷的方式操作。
在一些实施例中，所述控制模块包括印刷电路板，所述印刷电路板与所述汇流排电连接，所述壳体包括端子容纳部和印刷电路板容纳部，所述汇流排正端子和汇流排负端子被设置在所述端子容纳部中，所述印刷电路板设置在所述印刷电路板容纳部中，且其中，在垂直于所述第二方向的平面内观察，所述端子容纳部和印刷电路板容纳部位于所述壳体的相对侧。
在一些实施例中，所述电加热装置还包括加热单元，所述控制模块连接至所述加热单元。
本申请还提出了一种供暖、通风和/或空调装置，其包括如上所述的电加热装置。
本申请还提出了一种机动车辆，其包括如上所述的供暖、通风和/或空调装置。

具体实施方式
图1中示出了根据本申请的电加热装置1。该电加热装置1配备在机动车辆的供暖、通风和/或空调装置中。电加热装置1例如设置在机动车辆的中央操作面板(未示出)下方的空间内且大体平行于所述中央操作面板。电加热装置1布置在鼓风机的下游，鼓风机送出的空气通过电加热装置1且被加热，最后经由中央操作面板的格栅到达驾驶舱的乘客区域。
参照图1来定义下文中使用的xyz坐标系。如图1所示，电加热装置1大体为在一平面内纵向延伸的纵长板状体。定义该平面内电加热装置1纵向延伸的方向为x轴方向，在该平面内与x轴方向垂直的方向为z轴方向。y轴方向与x轴方向、z轴方向均垂直，y轴方向也称为厚度方向。如图1中观察到的，电加热装置1沿y轴方向的尺寸小于其沿x、z轴方向的尺寸。
如图1所示，电加热装置1包括加热单元H。在一些实施例中，电加热装置1可包括多个沿x轴方向延伸的加热单元H，该多个加热单元H相互平行地布置。电加热装置1还包括壳体2和容纳在壳体2中的控制模块。沿x轴方向，壳体2例如布置在加热单元H的一端，壳体2中的控制模块连接至所述加热单元H。
图2中示出了根据现有技术的壳体2。在传统的设计中，壳体2在平行于xz平面的表面上设置有接插件S。线束和插头(未示出)沿y轴方向插入到该接插件S中，从而允许外部电源向电加热装置1的控制模块供电，控制模块再进一步向加热单元H供电。这种设计存在一定的局限性：由于电加热装置1设置在机动车辆的中央操作面板下方，电加热装置1的安装空间沿y轴方向(或称厚度方向)非常有限。一旦在平行于xz平面的表面上设置接插件S，电加热装置1连同线束和插头将在y轴方向上具备较大的尺寸，无法满足电加热装置1在沿y轴方向的狭窄空间内的安装要求。
图3中示出了根据本申请的壳体2。所述壳体2呈块状且其沿z轴方向的尺寸大于其沿y轴方向的尺寸。线束4用于输入电流，其连接至控制模块， 以使得外部电源向控制模块供电。
图4中示出了壳体2内部的控制模块和连接至控制模块的线束4，为更好地示出控制模块和线束4，壳体2的一部分被隐去。如图4所示，控制模块包括汇流排3。如图5更清晰示出的，汇流排3包括形成用于线束4的接口的汇流排正端子3A和汇流排负端子3B。线束4包括线束正端子4A和线束负端子4B。如图4和图6所示，在所述接口处，所述线束正端子4A和线束负端子4B与相应的汇流排正端子3A和汇流排负端子3B电连接。
与现有技术不同的是，如图3所示，在根据本申请的电加热装置1中，线束4沿z轴方向延伸至由汇流排正端子3A和负端子形成的接口处。相对于现有设计而言，这样的设计使得电加热装置1的壳体2在y轴方向不具有额外的厚度，提供了电加热装置1对于沿y轴方向较为狭窄的安装环境的良好适应性。
在一些实施例中，线束4通过设置在壳体2壁中的出线孔5延伸到壳体2的内部，使得线束正端子4A和线束负端子4B在壳体2的内部与汇流排正端子3A和汇流排负端子3B相连接。例如，参考图6和图7，所述壳体2在大体垂直于z轴方向的壁处可包括出线孔5，所述出线孔5允许所述线束4沿z轴方向进入所述壳体2内部并延伸至所述接口。出线孔5的数量例如为两个，一个出线孔5用于线束正端子4A，另一个出线孔5用于线束负端子4B。两个出线孔5例如沿着x轴方向排布，从而更合理地利用y轴方向的有限空间。
可选地，如图4和图6所示，汇流排正端子3A和汇流排负端子3B压接至相应的线束正端子4A和线束负端子4B。采用压接的方案，可以较低的成本为汇流排3和线束4的连接提供良好的抗拉拔性能，由此实现汇流排正端子3A、汇流排负端子3B和线束正端子4A和线束负端子4B的可靠连接。
可选地，所述汇流排正端子3A和汇流排负端子3B焊接至相应的线束正端子4A和线束负端子4B。
控制模块可包括印刷电路板，所述印刷电路板与所述汇流排电连接。如图4所示，所述壳体2包括端子容纳部8和印刷电路板容纳部9。所述汇流排正端子3A和汇流排负端子3B被设置在所述端子容纳部8中，所述印刷电路板设置在所述印刷电路板容纳部9中。在xz平面内观察，所述端子容纳部 8和印刷电路板容纳部9分别位于所述壳体2的相对侧21、22。端子容纳部8和印刷电路板容纳部9在空间上相互分隔，由此，汇流排3与线束4的连接可以在相对独立的空间内进行，一方面不会对印刷电路板造成影响，一方面也便于布置相应的工装，以实现汇流排3与线束4的相应端子之间的连接。
参考图7，在一些实施例中，所述壳体2可包括第一壳体2A和第二壳体2B。所述第一壳体2A和第二壳体2B沿y轴方向组装在一起且共同界定壳体2的内部空间。出线孔5包括第一半部5A和第二半部5B，所述第一半部5A形成在所述第一壳体2A中，所述第二半部5B形成在所述第二壳体2B中。以这样的方式，线束4和汇流排3的连接以及壳体2的组装可以以简单的方式进行，即先完成线束4和汇流排3的连接，再将第一壳体2A和第二壳体2B组装在一起。
优选地，如图7所示，所述第一壳体2A和第二壳体2B通过卡扣结构7组装在一起。由此，第一壳体2A和第二壳体2B的组装可以以简单快捷的方式操作。
在另一些实施例(未示出)中，可在壳体2的大体垂直于z轴的壁的外表面设置有接插件，汇流排正端子3A和汇流排负端子3B从壳体2的外表面处露出。由此，所述插接件形成用于线束4的接口，以与沿z轴方向延伸的线束4形成电连接。采用插接件的方案，可以简单快捷的方式实现汇流排3和线束4的可靠连接。
优选地，在一些实施例中，z轴方向为重力方向，即线束4沿重力方向延伸至由汇流排正端子3A和负端子3B形成的接口处。线束4的接口处往往存在有缝隙，水或灰尘容易经由这些缝隙进入壳体2的内部。在本申请中，由于将线束4的延伸方向布置在重力方向，水或灰尘由于重力的作用不容易进入到壳体2内，从而起到防水防尘的效果。
图8是根据本申请的电加热装置的壳体的一部分。为了示出壳体的内部结构，壳体的上半部分以及壳体内的汇流排、印刷电路板被隐去。参照图8，壳体2可包括从壳体2的内表面沿y轴方向凸起的绝缘肋6。绝缘肋6沿z轴方向延伸，所述汇流排正端子3A和汇流排负端子3B分别布置在所述绝缘肋6的一侧(见图4和图6)。由此，可避免汇流排正端子3A和负端子之间的短路风险。
本申请的进一步特征可以在权利要求、附图和附图的说明中发现。以上在说明书中提到的特征和特征组合以及进一步在附图说明和/或单独在附图中所示的特征和特征组合不仅用于分别指出的组合，还用在其他组合或单独使用，而不违背本发明的范围。在图中没有明确显示且解释、但是通过单独的特征组合从被解释细节呈现且可被产生的本发明的细节由此成为被包括和被披露的。因此，不具有原始形成的独立权利要求的所有特征的细节和特征组合也应被视为被披露的。
