Description
技术领域
本发明涉及机动车辆的集成照明的车身元件和具有这种元件的车辆。
更具体地,本发明涉及集成到车身中并允许根据不同照明模式的光信号或照明信号的扩散装置。
背景技术
已经有许多照明装置和/或信号装置安装在机动车辆上。
这些装置是强制性的,通常包括容纳在车身的内部隔室中的光源(白炽灯、LED灯、氙灯等),其通过透明或半透明材料的壁与外部隔离。这种照明装置尤其用作前灯或投射灯(远光灯、十字灯、位置灯、尾灯、转向灯、制动警示灯等)。
当今,机动车辆设计旨在将照明装置完全集成到车身的型材中,并且从这个角度来看,机动车辆的投射灯或车灯通过组装经由注塑成型单独制造的多个部件而制成。这些部件的形状对于每个车辆型号或每个制造商是特定的,并且其中一些具有金属化的表面层,如文献FR 3 013 739和FR 3 036 633中所描述。
文献EP2746106提出,来自光源的光仅通过选择性地位于照明装置的盖子的壁上的透明区域投射,而其它区域是不透明的和/或具有遮挡特性。
EP952388公开了一种机动车辆的后灯,其盖子设置有多层红色涂层,其涂层的光的扩散特性适合于照明装置的每个功能。
在US 4 855 877中,尾灯的照明装置包括多个并置的隔室,每个隔室包围至少一个光源。该装置由盖子封闭,该盖子由内部部件和外部部件的组装形成,该外部部件包括透明区域和具有不同颜色的透明和不透明条纹交替的区域。
然而,该风格的最新发展在于,出于美观或功能目的,在车身的一些部件上集成用于光信号的显示装置,其在颜色和几何形状的方面上都是可变的。
然而,已知照明装置的结构不适用于此目的,因为这些装置被设计并专用于在车辆的路径上投射光或发信号通知其方向或其状况。
另外,出于规章原因,已知的照明装置旨在安装在车身的特定位置,这与当前和未来的项目不对应。
发明内容
本发明的目的在于,通过提供一种改进的车身元件来解决现有技术所带来的技术问题,该车身元件设有扩散信号性照明或显示性照明的装置,该装置可以在颜色和几何形状上变化。
本发明的改进兼顾了在视觉方面和车辆集成美学方面的风格期望以及信息呈现的功能要求。
根据本发明,该目的通过一种机动车辆的车身元件实现,该车体元件包括壁,所述壁在其第一表面上具有扩散区域,所述扩散区域扩散由与所述第一表面相对设置的至少一个光源发出的光;所述壁在其第二表面上还包括光的遮挡区域,其特征在于,所述遮挡区域由形成光的扩散区域的间隔空间隔开。
根据第一变型,所述遮挡区域形成不透明块。
优选地,形成遮挡区域的所述块通过桥接件连接。
根据第二变型,光的扩散区域由形成所述壁的内表面的半透明片制成。
根据这最后两个变型的有利特征,所述壁由半透明片组装在不透明块上构成。
优选地,所述不透明块通过“钉(bouterollage)”在半透明片上来支承确保其锚定的销。
根据另一特征,形成光的的扩散区域的所述间隔空间由密封槽构成。
根据本发明的车身元件的特定变型,形成扩散区域的所述间隔空间各自设有面对的光源。
优选地,所述光源是称为红绿蓝(RGB)的LED,每个RGB LED由微处理器独立控制,以产生光信号。
根据本发明的又一变型,遮挡区域设有金属化涂层。
本发明的另一个目的是一种机动车辆,其提供或构造有至少一个具有上述特征的车身元件。
显示在本发明的车身元件上的光信号可以是可变的以适应需要(方向指示灯、日间行车灯、信号灯)并且以受控和可选择的方式在设置在扩散光的遮挡区域之间的间隔空间中移动。
由于这些扩散空间的精细度,本发明的车身元件允许呈现独特且原始的光信号,其尺寸小于标准照明装置所允许的尺寸,因此与现行法规兼容。
通过在强度、颜色和频率上独立地控制光源,本发明还提供了根据行驶阶段、车辆的类型和型号以及在其整个寿命期间改变光图案的可能性。
最后,本发明的实施例包括在半透明片上附接遮挡块的组装,从而允许容易地管理该车身元件的特别是通过塑料的注塑成型的工业制造过程。
特别地,对于表观遮挡区域表面的美学目的的处理可以从原材料的原始染色开始,通过水传递(hytrotransfert)、热传递或涂料操作进行硬铬电镀而不遮蔽车身的其它部分。
此外,由于其简单的结构和可变化的外观,本发明的元件可以紧凑且美观地集成在所有类型的机动车辆的车身中,而不会产生线条的断裂。
因此,根据本发明的改进的车身元件可以形成机动车辆的全部或部分车身,例如前挡板或后挡板、车门侧板、发动机罩等,或者稍后通过切割、插入和固定到车身而集成在车辆中。
通过调整光源的特性和光的扩散区域的特性,本发明的车身元件也可以用作照明装置或信号调节装置。
附图说明
通过阅读下文的描述并参照以下详细示出的附图,使得本发明的其它特征和优点得以显现。
图1示出了根据本发明的车身元件的实施例的正视图。
图2A和图2B分别示出了图1的车身元件的实施例的前部和后部的局部剖视图。
图3A至图3F示出了处于不同照明模式的图1的车身元件的正视图。
为了清楚起见,在所有附图中,相同或相似的元件用相同的附图标记表示。
具体实施方式
当然,上文呈现和下文描述的附图所示的实施例是通过非限制性的示例给出的。图1、图2A和图2B示出了本发明的车身元件的实施例,其包括集成的照明或照亮装置。这些照明装置包括壁1和隔室2(图2A和2B);壁1遮挡隔间2。
壁1包括所谓的外表面和内表面。外表面是指从车辆外部可见的表面,内表面是指面向隔室2不可见的表面。隔室2包围灯箱,灯箱包括至少部分地面向壁1的内表面的至少一个光源(未示出)。
在壁1上界定出是由光源发射的光的扩散区域11和光的遮挡区域12。根据本发明的各种变型,扩散区域11和遮挡区域12可以具有不同的形式和几何形状。
遮光区域12由间隔空间10隔开,间隔空间形成从隔室2到外部的光的扩散区域11。因此,外部观察者仅通过扩散区域11看到光源发出的光。
在附图所示的实施例中,遮挡区域12由在壁1的外表面上附接的不透明块12a实现,并由尺寸非常小的桥接件12b连接。这些桥接件12b在块12a之间提供机械连接,以形成单件式的块,该块例如可以通过塑料或热塑性材料(聚丙烯等)的注塑成型来实现。
光的扩散区域11由形成壁1的内表面的半透明片11a制成,并且在块12a之间被界定。优选地,该壁由不透明块12a组装在半透明片11a上构成。然后,在这里形成光的扩散区域11的块12a之间的空间10由狭窄且密封的槽形成。
将不透明块12a固定在半透明片11a上是通过电镀和插入然后将由不透明块12a的内表面承载的销12c锚定在穿过半透明片11a形成的孔中而制成的。这种所谓的“钉”的操作类似于铆接,并且包括可能通过在加热和加压的情况下来挤压在片11a的内表面上突出的销12c的端部或头部,从而以密封的方式联接块12a。
根据未示出的另一实施例,不透明块和半透明片可以通过在块之间提供自由的间隔空间而通过单次包覆成型操作制成。
根据又一实施例,通过穿过外部不透明块来蚀刻壁1直到到达片11a来产生光的扩散区域。在适当的情况下,光的遮挡区域12可以设置有金属化涂层,其染色与车身的染色相同。
根据本发明的优选变型,在遮挡块12a之间形成的光的扩散槽的间隔空间10各自设置有面对的光源(未示出)。这些光源有利地由二极管或RGB LED构成,每个二极管或RGBLED由微处理器独立地控制,并且其运行是自动的或由驾驶员控制。
因此,根据图3B至图3F所示的各个示意图,可以根据预定程序执行槽10的照明,从没有照明的休止状态开始(图3A),该程序具有本发明的车身元件上的强度、颜色、运动和位置的变化,以产生固定的、间歇的、遮蔽的或者更一般地活动的并且在槽10的网格上移动的光信号。
在不透明的遮挡块12a由正方形或矩形块组成的情况下,狭窄的槽10因此在基本竖直和水平的方向上延伸,这允许“棒”型印刷(typographique)字体的发光显示与数字屏幕的方式一致。
然而,并且在不脱离本发明的范围的情况下,可以设置为:光的遮挡区域可以由块组成,块各自的几何形状在各个块之间不相同,并且在它们之间界定的光的扩散的间隔空间的尺寸在整个车身元件上不均一。
本发明还涉及一种提供或构造有至少一个具有上述特征的车身元件的机动车辆。
