Description

形成用于车辆的撞击板的方法
技术领域
本发明涉及具有分裂线的撞击板和形成撞击板的方法，如果发生车辆碰撞，安全气囊门沿该分裂线裂开，更具体地，本发明涉及一种形成用于车辆的撞击板的方法，其中安全气囊门和撞击板是使用一体化的型芯注塑成型的，通过鼓风步骤调整撞击板的分裂线厚度，这样除降低制造成本之外，还防止分裂线脱色，并防止出现缩痕。
背景技术
通常，撞击板安装在车辆前部方向盘和仪表所在处。
通常通过向模具注入合成树脂来制造撞击板。目前在车辆中，在靠近乘客座椅处增设了安全气囊。安全气囊门设置在撞击板容纳用于乘客座椅的安装气囊的那部分上，并被用激光形成的分离线限制，以允许安全气囊膨胀。最近，通过同时注入两种树脂的双液成型方法制造撞击板。通过双液成型方法，用具有高柔软度的材料制造其中安装了用于乘客座椅的安全气囊的部分和分裂线，从而使安全气囊门更易于打开。
图1a图解说明了传统的通过双液成型方法制造的撞击板10。
安全气囊门20和具有用于将安全气囊门20与周围部分分离的分裂线12的撞击板10由不同的树脂制成，以易于打开安全气囊门20。为此目的，使用双液成型方法。
通常，撞击板10主要由具有高的刚性的PPF(聚丙烯纤维)制成，而安全气囊门20主要由具有高柔软度的TPO(热塑性烯烃)树脂或TPE(热塑性弹性体)树脂制成。
但是传统的双液成型方法存在使用不同种类的树脂的问题，使得分裂线脱色，因而产生了不美观的外观，并出现缩痕。
为了克服该问题，使用激光光刻方法，如图1b所示。该方法防止分裂线12脱色。但是，由于通过激光处理形成撞击板10的分裂线12，需要另外的过程，从而增加了制造成本。
同时，也可以使用原位成型方法作为形成撞击板10的方法，如图1c所示。根据该方法，型芯40中设有带凹口的突起，从而在注塑产品中形成分裂线12。但是，该方法存在模具结构复杂和因分裂线12厚度的突然变化可能出现缩痕的问题。
本背景技术部分公开的信息仅用于加强对本发明全面背景的理解，不应被认为是对该信息构成本领域技术人员已知的现有技术的认可和任何形式的暗示。
发明内容
因此，提出了本发明的各方面以克服上述问题。本发明的各方面提供了一种形成用于车辆的撞击板的新方法和通过该方法制造的撞击板，其除防止因复杂的模具结构而增加制造成本之外，还防止分裂线脱色，并防止出现缩痕。
本发明的一个方面的目的是提供形成用于车辆的撞击板的方法。该方法可以包括将熔融树脂注入并充满具有型芯和型腔的模具，以便通过注塑成型形成与安全气囊门一体化的撞击板，
除防止充满的树脂回流之外，注塑过程中还保持树脂上的常压不变，调整空气喷嘴以形成分裂线的横截面，撞击板在该横截面处与安全气囊门分离，通过插入由型芯限定的风道的空气喷嘴鼓风，从而控制分裂线的厚度，和/或冷却熔融树脂。
该方法可以进一步包括在鼓风之前测量熔融树脂的温度。
鼓风步骤可以进一步包括感测注入的空气的压强。
本发明的方法和装置具有其他特征和优点，通过并入本文的附图和下文的具体实施方式，其共同用于更详细解释本发明的特定原理，这些特征和优点将显而易见或被更详细地阐明。

图1b是显示另一传统的通过激光光刻方法制造的用于车辆的撞击板的示意图。

图4a是显示根据本发明的形成方法的示意性温度感测步骤和压强感测步骤的示意图。
图4b是显示根据本发明的用于车辆的撞击板的示意性分裂线的厚度的示意图。
具体实施方式
现在将详细地参照本发明的各实施例和在附图中图解的及在下文描述的示例。虽然将结合示意性实施例描述本发明，但是应理解本说明书不是用于将本发明局限于那些示意性实施例。相反，本发明用于不仅涵盖示意性实施例，还涵盖由所附权利要求所限定的本发明的实质和范围内所包括的各种替换、修改、等价形式和其他实施例。
如图2所示，安全气囊3以能容纳在罩体1中的方式安装在车辆上。罩体1被安全气囊门20覆盖。分裂线12设置在撞击板10的安全气囊门20上的预设位置。减小分裂线12的截面厚度，从而在车辆碰撞过程中安全气囊门20比撞击板10更易于裂开。因此，当发生车辆碰撞时，分裂线12裂开，从而打开安全气囊门20，安装在罩体1中的安全气囊3膨胀，从而保护乘客。
为了生产撞击板10和安全气囊门20，可以使用注塑成型方法。
如图3a所示，在与车辆的安全气囊门20一体化的撞击板10的型芯40中形成风道42，从而将空气注入风道42.
为了制造撞击板10，熔融树脂50进入包括型芯40和型腔30的模具。在这种状态下，压强作用在模具中的树脂50上。
如图3b所示，为了防止装满的树脂回流并获得具有所需形状的注塑成型产品，执行压强保持步骤。在该步骤中，向模具中的树脂50施加压强，保持足以形成撞击板10的形状的压强不变。
在已完成压强保持步骤之后，执行使用空气喷嘴的截面调整步骤。在该步骤中，将空气喷嘴34插入在型芯40中形成的风道42，空气喷嘴34具有所需的大小的横截面以形成分裂线，因此确定了分裂线12的截面的形状。
在截面调整步骤中，确定当碰撞超过预设水平时裂开的分裂线12的截面形状。
在完成了截面调整步骤之后，执行鼓风步骤。在该步骤中，将空气喷嘴34插入风道42以将空气送进风道42。通过鼓风步骤，可以调整在撞击板10上形成的分裂线12的厚度t。
如图4a所示，优选地，形成用于车辆的撞击板的方法进一步包括温度感测步骤和压强感测步骤。温度感测步骤在鼓风步骤之前测量熔融树脂50的温度。压强感测步骤测量在鼓风步骤中风道42中流动的空气的压强。
为了调整撞击板10的分裂线12的截面厚度，必须在其中的树脂冷却之前注入空气。因此，为了易于形成分裂线，使用温度传感器60测量树脂50的温度。之后，在适合空气注入的温度执行鼓风步骤。
此外，根据鼓风步骤中注入风道42的空气的压强，确定分裂线12的厚度。因此，为了注入具有适当压强的空气，优选使用压力传感器70测量和控制空气的压强。
如图4b所示，在执行了上述形成撞击板的步骤之后，通过从在注塑成型过程中插入风道42的空气喷嘴34供应的空气，撞击板10具有具有预定厚度t的分裂线12。因此，安全气囊门20沿分裂线12设置在撞击板10上。
如上所述，本发明提供了形成用于车辆的撞击板的方法，该方法防止分裂线脱色，并防止出现缩痕，另外还具有降低的制造成本。
为了便于解释和所附权利要求的定义，术语“上部”等用于参考图中显示的特征的位置描述例示性实施方案的这些特征。
前面对本发明的具体例示性实施方案的描述是为了说明和描述的目的。前面的描述并不想要成为毫无遗漏的，也不是想要把本发明限制为所公开的精确形式，显然，根据上述教导很多修改形式和变化形式都是可能的。选择例示性实施方案并进行描述以解释本发明的特定原理及其实际应用，从而使得本领域的其它技术人员能够实现并利用本发明的不同例示性实施方案及其不同选择形式和修改形式。本发明的范围意在由所附权利要求书及其等价形式所限定。
