车辆标志主要便于销售者、使用者、维修人员、交通管理部门等等识别车辆的身份。特别地，在车辆标志能发光的情况下，能进一步提升可见性、美观性以及安全性。
发明内容
本发明的目的在于提出一种车辆标志组件，其能够成本有利地制成。
本发明的目的还在于提出一种用于形成车辆标志组件的方法。
根据本发明提出了一种车辆标志组件，其具有壳体和外罩，由壳体和外罩围成内部空间，在该内部空间中容纳有发光组件、光扩散组件，其中，在外罩的面向发光组件的内侧设置有覆层，从而呈现出车辆标志，并且外罩设有透光部位。光能通过透光部位离开外罩。
通过该方案，由于外罩本身具有一定的厚度，在覆层设置于外罩内侧的情况下，能有利地保护形成车辆标志的覆层，从而具有极好的抗刮性。
覆层例如由第一子覆层以及第二子覆层构成。当然，覆层还可具有更多子覆层，例如覆盖第一子覆层以及第二子覆层的透光的保护层。在此，相应的子覆层可理解成在不同的工步中施加的覆层。示例性地，第一子覆层为丝网印刷覆层，而第二覆层为电镀层。子覆层本身或彼此可具有不同的颜色。
根据本发明的实施方式，第二子覆层覆盖第一子覆层。这能够进一步有利于防止第一子覆层的脱落。在此，要理解的是，第二子覆层可完全或部分地覆盖第一子覆层。优选地，第二子覆层完全覆盖第 一子覆层。当然，第二子覆层还能附加地至少部分地占据外罩内侧的未被第一子覆层的区域。
根据本发明的实施方式，第二子覆层为透光层，以形成透光部位。
根据本发明的实施方式，第一子覆层和第二子覆层都为不透光层，其中，在第一子覆层与第二子覆层的交界处设置有预定宽度的镂空部，以形成透光部位。
根据本发明的实施方式，光扩散组件包括第一光扩散件和第二光扩散件，第一光扩散件布置在发光组件上，第二光扩散件布置在第一光扩散件和外罩之间。扩散件可以透明或半透明。必要时，扩散件的表面可具有覆层、粗糙化层或具有微刻面，以有助于光扩散。
根据本发明的实施方式，第一光扩散件的横截面具有半圆形的内轮廓和由至少一个弧形区段构成的外轮廓，例如半“8”字形的外轮廓，以扩散发光组件的光源的出光角度。
根据本发明的实施方式，第一光扩散件为环状，发光组件的光源环形地布置。
根据本发明的实施方式，第二光扩散件为板状，其具有穿孔。
根据本发明的实施方式，在第一光扩散件的外周设置有定位结构和锁定结构，壳体中设置有配合定位结构和配合锁定结构，它们相互作用，以将发光组件固定在第一光扩散件和壳体之间；在第二光扩散件的外周同样设置有定位结构和锁定结构，壳体中设置有配合定位结构和配合锁定结构，它们相互作用，以实现第二光扩散件的固定。
根据本发明的实施方式，发光组件为印刷电路板组件。
根据本发明的实施方式，发光组件配有散热组件，该散热组件处在发光组件与壳体之间，其中，在散热组件与发光组件和壳体接触的两侧中的至少一侧设置有散热层。
对于提出的用于形成车辆标志组件的方法，包括：
-提供膜，在预处理后在膜上印刷覆层，待覆层固化后进行成型，将成型好的膜放置在模具中并施加注塑料，以形成外罩的外层；
-连接外罩与装配有发光组件与光扩散组件的壳体；
其中，在与覆层所在的一侧相反的一侧施加注塑料。
通过该方法，特别通过印刷方法、例如丝网印刷形成第一子覆层，这能够实现简单地制造。此外，还能实现具有多种颜色的第一子覆层。由于覆层处在内侧，还能实现极好的抗刮性。
根据本发明的实施方式，覆层可包括第一子覆层以及第二子覆层，其中，在施加第一子覆层之后施加第二子覆层。
第二子覆层可覆盖第一子覆层，第二子覆层为透光层。
根据本发明的实施方式，方法还包括在外罩的内侧进行蚀刻，使得在第一子覆层和第二子覆层之间形成镂空部，以用于透光。
根据本发明的实施方式，膜与注塑料由相同的材料构成。这能够实现膜与注塑料的好的结合，由此形成均质的外罩本体。
附图说明
下面借助附图进一步说明本发明。其中，

图2示出了图1的车辆标志组件的部分装配好的图示；
图3示出了图1的车辆标志组件的外罩的分解图示；
图4示出了图1的车辆标志组件的外罩的前视图；
图5示出了根据另一实施例的车辆标志组件的外罩的前视图；
图6示出了图4的外罩的沿线A-A的截面图；
图7示出了图5的外罩的沿线B-B的截面图。
具体实施方式
在下文中示例性地说明了本发明的实施方式。如本领域的技术人员应该意识到的那样，在不背离本发明的构思的情况下，所说明的实施方式可以各种不同的方式进行修改。因此，附图和说明书本质上为示例性而非限制性的。在下文中，相同的附图标记通常表示功能相同或相似的元件。
车辆标志组件具有壳体和外罩。通过壳体将车辆标志组件安装在 车辆的预定的位置，例如车辆的前部的栅格、尾部的行李舱盖、侧部或其他合适的地方。外罩上具有车辆标志，其呈现车辆品牌、厂商或其他信息，并且能够很容易地被看见。
根据图1示出了车辆标志组件1的一实施例。该车辆标志组件1除了壳体10和外罩70之外，还具有发光组件40和光扩散组件2，必要时还具有散热组件20和散热层30，它们容纳在由壳体10和外罩70限定的内部空间中。
如从图1和图4中可见的那样，外罩70上设有车辆标识。在该示例中，车辆标识是由四个扇形区域形成的组合图形，其居中地位于外罩的端面处，外罩端面的未被车辆标识占据的其他区域可看作背景区域。当然，车辆标识可具有期望的任意形状。附加地，还可设置包围车辆标识的未示出的一圈边界环。外罩70本身由诸如聚合物材料的任意适宜的透光材料制成为刚性结构。在外罩的面向壳体的内侧设有第一子覆层703，其部分地占据该内侧并且形成车辆标志。在内侧还设有第二子覆层704，其至少部分地占据内侧的未被第一子覆层占据的其他部分。
在一方案中，在第一子覆层与第二子覆层恰好互补地占据外罩70的内侧的情况下，第一子覆层与第二子覆层可具有不同的颜色。在这种情况下，两种覆层中的至少一种可以透射光，由此透光层形成透光部位，以使光穿过外罩向外出射。
在另一方案中，第二子覆层还可至少部分地覆盖第一子覆层，甚至完全覆盖第一子覆层。在这种情况下，第一子覆层为不透光层，第二子覆层为透光层，由此第二子覆层的覆盖内侧的未被第一子覆层占据的部分形成透光部位，使得光穿过外罩向外出射。在图3中以分解图示为了阐述的目的示出了第二子覆层704完全覆盖第一子覆层703。换句话说，在该示例中，第一子覆层处在外罩本体与第二子覆层704之间。
在又一方案中，第二子覆层处在内侧的未被第一子覆层占据的区域中。然而，在第一子覆层与第二子覆层之间形成有镂空部705，如 可从图5中看出的那样。在这种情况下，第一子覆层与第二子覆层都可为不透光层，光可从镂空部705出射。因此，镂空部形成透光部位。
因此，透光部位可为车辆标志本身、车辆标志的内周边、车辆标志的外周边、车辆标志的内外周边或其他合适的部位。
相应地，发光组件40布置在外罩70后面。发光组件具有任意形式的光源，例如发光二极管、有机发光二极管、聚合物发光二极管或其他形式的发光器件。光源可由车载电源供电。附加设置的控制器、例如车身控制器可用于控制光源的发光。还可设置用于车辆标志组件的单独的控制器。为了控制发光组件的发光强度，可通过控制器例如控制通过光源的电流大小。
在示出的示例中，光源呈发光二级管401的形式，其环形地布置在PCB板402上。光源在PCB板上的还可根据需要具有其他的排布形式。此外，在PCB板上还安装有其他电子构件。
在使用发光二级管的情况下，光源可看作点光源。为了使光均匀地离开外罩，在发光组件40的上方布置有光扩散组件2。在示出的示例中，光扩散组件2包括第一光扩散件50和第二光扩散件60，其中，第一光扩散件50布置在发光组件40上并且主要用于扩大光源发出的光的发散角，第二光扩散件60布置在第一光扩散件50和外罩70之间并且主要用于使光均匀化。在此，相应的光扩散件可进行相关的处理，例如设置覆层、表面粗糙化层或其他微型结构。
第一光扩散件50的基本形状匹配于光源形成的几何形状。在此，第一光扩散件50具有同样为环形的基体，其盖住光源。第一光扩散件50的基体的横截面具有半圆形的内轮廓508和半“8”字形的外轮廓509，由此将光朝环的内外两侧的方向扩散。这还适用于其他形状的第一光扩散件50。
第二光扩散件60基本上为板状，其由具有光扩散能力的材料构成。第二光扩散件60可设有穿孔610，以利于在它两侧的空间的空气流通，从而避免特别在外罩处出现冷凝现象。
光扩散组件40固定在壳体上。为此，壳体10上一体地设有用于 第一光扩散件50和第二光扩散件60的固定结构。
在第一光扩散件50的外周设置有第一定位结构和第一锁定结构506，壳体10中设置有第一配合定位结构和第一配合锁定结构106，它们相互作用，以将发光组件40固定在第一光扩散件50和所述壳体10之间。第一定位结构可为在外周的弹性突舌505、具有槽口的接片507或它们的组合的形式。第一配合定位结构可为成型在壳体处的卡口105、引导壁107或它们的组合的形式。在接合时，在接片507的槽口经由引导壁107的引导的情况下，突舌505伸入卡口105中。此时，呈盖帽的形式的、具有开口的第一锁定结构506相对于呈具有螺纹孔的凸起的形式的第一配合锁定结构106占据正确的位置。在拧入螺钉之后，实现第一光扩散件50的固定，并且由此将发光组件40锁定在第一光扩散件50和壳体之间。
在第二光扩散件60的外周设置有第二定位结构和第二锁定结构608，壳体10设置有第二配合定位结构和第二配合锁定结构108。第二定位结构可为在第二光扩散件60的外周的凸片609、凹口611或它们的组合的形式。第二配合定位结构可为在壳体处的成对的引导壁109、隆起111或它们的组合的形式。在接合时，凸片609通过引导壁109来引导，嵌入凹口611中的隆起111保证第二光扩散件相对于壳体占据正确的位置。在此同时，呈锁块的形式的第二配合锁定结构108接合到第二锁定结构608的扣眼中，由此实现第二光扩散件60相对于壳体的固定。
上文提到的壳体的配合定位结构和配合锁定结构可设置在壳体的底部、外周处。
特别在发光组件40的PCB板的尺寸超过第一光扩散件时，PCB板402的外围设有槽口406、407，其匹配于第一光扩散件的定位结构和锁定结构。这还可附加地实现PCB板的定位。
为了有利于散热，为发光组件40配有散热组件20，其处在发光组件40与壳体40之间。散热组件20例如为由金属材料(诸如铝、铜、铜铝合金等等)制成的具有预定厚度的板。附加地，在散热组件 20与发光组件40和壳体分别接触的两侧中的至少一侧设置有散热层30。散热层可为由柔性材料制成的散热片，或者为散热膏。这进一步有利于散热。在示出的实例中示出了为散热片的散热层30，其处在发光组件可散热组件之间。在散热层30为片状时，它和散热组件20可具有和PCB板402相同的外周边轮廓。为此，散热层30和散热组件20可分别具有和PCB板的槽口406、407位置相对应的缺口306、307、206、207。当然，散热组件20可具有更大的尺寸，此时凹口中的一部分可为圆形穿口。
散热组件20还可具有用于PCB板402的定位栓209。为此，在PCB板和必要时散热层30中设有对于的定位孔409、309。
在发光组件40通过未示出的电气接头例如与车载电源建立电气连接时，必要时可在散热层30、散热组件20和壳体10中设有用于穿引电气接头的孔口304、204、104。
优选地，壳体10的用于光扩散组件和发光组件的配合定位结构和配合锁定结构一体地成型在壳体上，例如注塑成型在壳体的底部102、周边103处。这能够简化装配。
下面阐述用于制造上述车辆标志组件1的方法。
首先制造车辆标志组件1的外罩70。在此，尤其使用模内贴膜注塑方法。为此首先提供膜层702，其厚度例如为0.1mm、0.125mm、0.175mm。必要时，将膜层702裁切成预定的大小，并且进行诸如烘培、除尘等预处理。膜层702可由PET、PC、PMMA等构成。然后在膜层702上印刷第一子覆层703，其可呈现为车辆标识，例如为图像、文字或它们的组合。印刷例如为丝网印刷。第一子覆层中还可具有不同的颜色，这特别适用于具有多种颜色的车辆标识。在膜层702上印好第一子覆层703之后，将膜层放入烤箱内进行固化，示例性地，固化温度设置在80-100℃，固化时间为1-2小时。
接着对膜层进行热压和冲切，优选地进行3D热压，使得膜层匹配于随后要成型的外罩的内轮廓的造型。优选地，在热压和冲切之前可对膜层施加单层或双层保护膜，必要时进行冲孔，以用于定位。当 然，保护膜可在后续工序中移除。
将处理好的膜层放入模具中，进行注塑，以形成外罩70的外层701，其中，外层701处在膜层702的与施加有第一子覆层703的一侧相对而置的一侧。因此，外层与膜层的没有覆层的一侧直接结合。优选地，形成外层701的注塑料与形成膜层的材料相同，例如PET、PC、PMMA等，这能够实现外层与膜层的尽可能好的结合。在外层701的厚度较厚时，可采用多次注塑。优选地，外层701是透明的并且具有耐磨性。
为了施加第二子覆层704，可以利用各种真空涂覆工艺，包括但不限于物理气相沉积、化学气相沉积。可选地，还可使用电镀、化学镀、化学处理、电化学处理或本领域已知的其他涂覆方法。
示例性地，第一子覆层703为漆层，例如黑色漆层，第二子覆层704为金属覆层，例如镀铝层、镀铬层、镀银层等等。第二子覆层704完全覆盖第一子覆层703，并且还占据未被第一子覆层占据的其他区域。更确切地说，第二子覆层占据外罩70的整个内侧，如从图6的截面图示中看到的那样。当然，第二子覆层还可使用其他合适的材料，以获得需要的外观，例如银、铜等等。为了使外罩透光，可控制第二子覆层的厚度。厚度可根据需要的透光率来设置。例如，第二子覆层的厚度小于20nm，特别小于15nm，优选地在5至15nm之间。在激活光源时，光源可从穿过第二子覆层出射。
在另一示例中，第一子覆层与第二子覆层都为不透光层。在如上文所述的方式施加两种覆层之后，可通过蚀刻、例如激光蚀刻在第一子覆层与第二子覆层的交界处形成镂空部705，如从图7的截面图示中看到的那样。镂空部例如形成车辆标志的周边。在激活光源时，光源发出的光可从该镂空部出射。
第一子覆层与第二子覆层的颜色可根据需要来选择。每种覆层本身可具有不同的颜色。在光穿过覆层离开透镜时，可控制相应的覆层的厚度使得光可穿透。
当然，第二子覆层还可仅仅部分地占据外罩内侧的未被第一子覆 层占据的部分。因此，第二子覆层没有叠置地处在第一子覆层上。
附加地，还可在第二子覆层上施加透光的保护层。
在发光组件、光扩散组件以及必要时散热组件安装在壳体上之后，连接外罩与预装配好的壳体。为了防止车辆标志组件的内部电子件收到外部环境的湿气的影响，外罩与壳体气密地连接在一起，例如焊接、粘接。
因此，本公开提供了一种有利的车辆标志组件。由于形成标志的覆层设置在外罩内侧，可有效防止标志被刮伤。特别是通过模内贴膜注塑方法，由于膜层的优良的伸展性，可实现复杂的外形。同时，形成的车辆标志组件外层具有很好的表面耐磨性和耐化学特性。
本发明不限于上述结构，也可以采用其他的各种变体。虽然已经通过有限数量的实施方式描述了本发明，但是受益于本公开，本领域技术人员可以设计出不脱离在此公开的本发明的保护范围的其他实施方式。因此，本发明的保护范围应仅由所附权利要求限定。
