Description

鼓风机、通风装置、车座椅或电池系统、制造方法及设备 技术领域
本发明涉及一种用于车辆座椅或车辆动力电池系统的鼓风机、一种相应的用于车辆座椅或车辆动力电池系统的通风装置、一种相应的车辆座椅或车辆动力电池系统、一种相应的制造鼓风机的方法以及一种相应的实施该方法的加工设备。
背景技术
随着技术发展和人们对舒适性要求的提高，越来越多的车辆座椅配备有通风装置，以便改善身体与椅面接触部分的空气流通环境，从而即使长时间乘坐，身体与座椅的接触面也会干爽舒适。另外，随着油电混动及纯电动技术的普及与发展，对车辆动力电池的散热要求也越来越高。
作为通风装置的一个重要部件，鼓风机的性能和成本至关重要。用于控制鼓风机操作的控制装置、例如印刷电路板通常设置在壳体内，该控制装置需要通过连接装置与外部装置电连接，以便与外部装置进行通信和从外部装置接收电力。
目前，连接装置主要有两种方式：1)安装在印刷电路板上或以其它方式固定连接到印刷电路板上的单独的连接器，由于连接器与印刷电路板固定连接在一起，因此，连接器移动会带动印刷电路板也移动，从而在插拔连接器时可能会对印刷电路板造成损坏；2)从壳体中引出的线束，该线束一端电连接到印刷电路板，另一端设有插接头，这种方式复杂，可靠性不高，线束的布置也存在一定问题。
而且，无论哪种方式，成本都相对较高，制造也较为复杂。
为此，需要对现有的连接装置进行改进。

具体实施方式
为了使本发明所要解决的技术问题、技术方案以及有益的技术效果更加清楚明白，以下将结合附图以及多个示例性实施例对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用于解释本发明，而不是用于限制本发明的保护范围。
图1示出了根据本发明的一个示例性实施例的用于车辆座椅或车辆动力电池系统的鼓风机的一部分的分解立体图。图2示出了图1的鼓风机的所述一部分的从另一个角度观察的组装后的立体图。所述鼓风机在车辆座椅的通风装置中用于产生加压气体而充当气源或在车辆动力电池系统中充当散热装置。为了清楚起见，图1和图2中仅示出了与本发明的密切相关的部分。
如图1和图2所示，鼓风机1包括：电机11(在此仅示出了电机的一 部分)；控制装置12，其与电机11电连接，以控制电机11的操作；壳体13(在此也仅示出了一部分)，控制装置12设置在壳体13内；以及电连接器14，其具有多个引脚141，所述引脚141具有位于壳体13内的内端部1411和暴露于壳体13外的外端部1412，所述内端部1411与控制装置12电连接；其中，电连接器14的至少一部分在壳体13的壳体部分131的成型过程中一体地形成在壳体部分131上。电连接器14用于将鼓风机1的控制装置12与外部的相应装置电连接。
鼓风机1的壳体13可由多个部分组合而成，如上所述，图1和图2中仅示出了壳体13的一部分。鼓风机1可以被构造成离心式风扇。
优选地，鼓风机1的壳体13通常主要包括可彼此组装(例如但不限于通过卡扣连接)在一起的两个壳体半体。如图1和图2所示，壳体部分131可以被构造为一个壳体半体(下壳体半体)。
壳体13通常由塑料注塑成型，这不仅方便加工成型，而且具有较低的制造成本。
根据本发明的一个示例性实施例，电连接器14可被构造为插接式连接器。插接式连接器可方便、可靠地进行电连接。
如图1和图2所示，插接式连接器的引脚141可被构造成插针，所述插针被电连接器14的罩壳环绕着包围。这种电连接器比较常见，在此不再赘述。电连接器14的罩盖也优选由塑料制成。
如上所述，电连接器14的至少一部分、特别是整个电连接器14在壳体13的壳体部分131的成型过程中一体地形成在壳体部分131上，从而不需要单独配置和组装电连接器。在这种情况下，电连接器14由于固定在壳体部分131上，因此，其在插拔过程中也不会带动控制装置12，这是非常有利的。
虽然整个电连接器14在壳体部分131的成型过程中一体地形成在壳体部分131上是优选的，但理论上讲，使电连接器14的一部分在壳体部分131的成型过程中一体地形成在壳体部分131上也是有一定益处的，例如可以降低电连接器安装的工作量。理论上，电连接器14的一部分形成在一个壳体部分上，电连接器14的另一部分形成在另一壳体部分上，只要这两个壳 体部分在组装状态下能够配合形成电连接器14即可。
特别地，引脚141可以嵌埋在壳体13的壳体部分131中，这尤其通过注塑成型可以很容易地实现。
根据本发明的一个示例性实施例，控制装置12可被构造为印刷电路板(PCBA)。
如图2所示，电机11的定子111可固定安装在控制装置12上。尤其是在控制装置12为印刷电路板的情况下，电机11的定子111可以通过插针插入印刷电路板的连接孔(优选为通孔)中而固定到印刷电路板上。优选地，这种插接同时还可以提供电机11的定子111与印刷电路板之间的电连接。
为了确保连接的可靠性，还可以在插入部位施加焊料进行焊接或使用碰焊等工艺。
根据本发明的一个示例性实施例，内端部1411直接电连接到控制装置12。这意味着内端部1411直接延伸到控制装置12而通过内端部1411本身与控制装置12建立电连接，此时内端部1411与控制装置12之间不需要另外的电连接元件、例如导线。从而，可方便连接，简化设计。
类似地，如图2所示，内端部1411插接于控制装置12的电连接孔121中。附加性地或替代性地，内端部1411也可以通过焊接电连接到控制装置12。优选地，插接后再进行焊接，这样可靠性可以大大提高。
根据本发明的一个示例性实施例，引脚141的位于内端部1411与外端部1412之间的居间部分1413的至少一部分能够从壳体13外侧暴露，以提供用于对鼓风机1进行测试的测试电触点。在图1和图2中，由于暴露部分位于壳体部分131的下侧(外侧)，因此图中不可见。
如图2所示，根据本发明的一个示例性实施例，居间部分1413的至少一部分在壳体13内侧暴露。这种暴露便于分离开相邻引脚141，从而确保引脚141之间不会发生电短路，特别是在多个引脚141开始作为一个整体形成于壳体部分131中时。这将在下面结合对鼓风机1的制造过程的描述后更容易地理解。
如图1和图2所示，控制装置12设置在壳体部分131的内侧，例如可 通过设置在壳体部分131内侧的引导结构1311实现定位然后再例如通过其它结构实现固定或连接。该引导结构1311也可以在壳体部分131的成型过程中一体地形成。
根据本发明的一个示例性实施例，所述多个引脚141并排布置。
根据本发明的一个示例性实施例，所述多个引脚141的内端部1411侧向向外弯曲展开，以扩大内端部1411彼此之间的间距，这方便将引脚可靠地连接到控制装置12。这可从下面描述鼓风机1的制造过程时所给出的图中清楚地看出。
如图1和图2所示，根据本发明的一个示例性实施例，电连接器14形成于壳体13的外周处。优选地，电连接器14的至少一部分、特别是位于壳体13外的部分径向向外延伸。
根据本发明的一个示例性实施例，内端部1411的至少一部分可轴向延伸(可通过弯折实现)，从而可以方便地插入控制装置12的电连接孔121中进行连接。轴向是相对于电机11的旋转轴线而言的。
下面，将对图1和图2的鼓风机1的相关的制造过程(包括组装过程)进行描述。
图3示出了根据本发明的一个示例性实施例的用于制造鼓风机1的方法的流程图。
如图3所示，所述方法至少包括步骤S1和S2。在步骤S1中，将多个引脚141中的至少一个布置在用于成型壳体部分131的模具中。在步骤S2中，通过模具成型壳体部分131，以使电连接器14的至少一部分一体地形成在所述壳体部分131上。
图4、图5和图6示出了根据本发明的一个示例性实施例的用于制造鼓风机1的方法的示意性说明图。
图4示出了多个引脚141。在该示例性实施例中，所述多个引脚141组合成一个整体，这样可以方便地将多个引脚141一起布置在模具中，而且这种组合可以使多个引脚141相对位置固定地保持，从而不会在成型壳体部分131的过程中使引脚141错位。
为了将多个引脚141保持在一起，可将所述多个引脚141通过结合结 构组合成整体部件。
根据本发明的一个示例性实施例，所述整体部件通过冲压和/或模塑制造，所述结合结构包括连接在相邻引脚141之间的连接结构。在这种情况下，可以通过冲压导电板材、例如铜板形成图4所示的整体部件。这种方法简单可靠，但需要后续的分离操作。也可通过模塑将冲压分离的引脚形成为一个整体。
本领域的技术人员也可以想到，结合结构也可以采用其它方式，例如使用粘接剂粘接。在这种情况下，粘接剂可以选择为绝缘物，但要确保在成型壳体部分131的过程中不会破坏并能与成型材料很好地结合。
作为另一种可能的实施方式，也可通过模具中的保持结构将所述多个引脚141保持在模具中，以在成型壳体部分131的过程中位置稳定地保持所述多个引脚141。该保持结构可以开设在模具上。
图5以从壳体部分131内侧观察的俯视图示出了在成型壳体部分131后电连接器14一体形成在壳体部分131中的情况。
如图5所示，电连接器14一体地形成在壳体部分131上，优选地多个引脚141的居间部分1413的一部分在壳体部分131的内侧暴露。优选地，可将结合结构也展露出来。
图6示出了对多个引脚141进行分离而所述多个引脚141彼此电隔离后的情况。此时，多个引脚141之间的电连接、例如结合结构被破坏。
根据本发明的一个示例性实施例，该分离操作可以通过切割进行。
本领域的技术人员可以理解，所述方法还可包括：使引脚141直接电连接到控制装置12。
根据本发明的一个示例性实施例，所述方法还可包括：通过居间部分1413的至少一部分在壳体13外侧裸露形成的测试电触点对鼓风机1进行测试。这样，测试时不需要插拔电连接器14，从而可减少电连接器14的插拔次数，延长其使用寿命。
根据本发明的一个示例性实施例，在测试完成之后，可以使用绝缘材料、例如绝缘密封胶带封闭所述测试电触点。通过胶带封闭，可以在需要测试时再撕开胶带进行测试。
其它一些组装步骤参看以上描述可以很容易理解，在此不再赘述。
图7示出了一种用于实施用于制造鼓风机1的方法的加工设备的示意图。如图7所示，该加工设备100包括：传送台101，模具102放置在传送台101上；放置工位103，其用于执行步骤S1；以及成型工位104，其用于执行步骤S2。如图7所示，所述传送台101可优选地被构造为旋转式传送台，例如在图7中可沿顺时针方向转动。
如图7所示，根据本发明的一个示例性实施例，加工设备100还包括分离工位105，以分离多个引脚141而使多个引脚141彼此电隔离。
尽管这里详细描述了本发明的特定实施方式，但它们仅仅是为了解释的目的而给出的，而不应认为它们对本发明的范围构成限制。在不脱离本发明精神和范围的前提下，各种替换、变更和改造可被构想出来。
